Description

The present invention is a flexible packaging bag in which a film-like check nozzle (liquid pouring nozzle) with a self-sealing check function is provided in a protruding manner, together with a liquid material such as water, and a stock material such as fish and fish formed by housing a filter bag enclosing the non-self-supporting a soup material containing seasoning liquid for double pack package of free-standing outside packaging container is received and held becomes put out material containing seasoning liquid for double pack packaging structure It is about.

  Traditionally, stock materials such as fish buns, dried fish, dried seaweeds, and dried mushrooms have been used as a soup stock dashi pack as follows. First, after cutting or pulverizing the above-mentioned soup stock material, immersing it in water or seasoning liquid, extracting the stock ingredients as it is or by heating, and then filtering, centrifuging or distributing, etc. To remove the insoluble solid content of the soup stock after extraction, or to remove the soluble protein with a large molecular weight that causes elution into the liquid and cause turbidity and cages, etc., as a residue to obtain an extract filtrate . Then, the extracted filtrate is used as a liquid soup stock or as a liquid seasoning liquid with soup stock, or as a basic seasoning liquid, various food materials such as other seasonings and spices are added, or the concentration is adjusted. , Various seasonings with soup stock.

  Then, these liquid soup stock and soup stock seasoning as it is or after heat sterilization, filled into a container and sealed, then frozen and refrigerated, or after heat sterilization, aseptically at a certain temperature The container is filled and sealed as it is, or the container is filled and sealed as it is, and then the whole container is heated and sterilized to obtain a soup stock dashi pack or a soup stock liquid seasoning pack.

  However, such conventional liquid soup packs and liquid seasoning packs with soup stock require various processes such as the extraction process and the separation / purification process as described above. Disposal of soot and residue after extraction is also essential, and the cost is high.

  In addition, stock materials such as fish buns and dried fish are easily affected by the temperature and dissolved oxygen, etc., even if they are frozen and stored refrigerated, the flavor will evaporate over time. There was a problem that it changed and deteriorated due to oxidation, browning, and the like. In particular, conventional liquid soup packs and liquid seasoning packs with soup stock require a high-temperature (100 ° C or higher) heat sterilization step in order to impart storage stability at room temperature. In addition to the deterioration of the flavor of the material, it had a nasty smell.

  With respect to the above problems, in Patent Documents 1 to 3, the dashi material is housed and sealed in a liquid-permeable interior container (filter bag), and this is sealed and housed in an exterior container together with liquids such as water and liquid stock. Later, a heated or / and refrigerated but filled liquid pack is disclosed. According to this technology, the filter bag containing the dashi material is immersed in the liquid in the outer container, but it is basically kept in an anaerobic atmosphere except for dissolved oxygen in the liquid until it is opened. Therefore, there is a feature that the flavor does not deteriorate, and the filter effect by the filter back prevents the stock material from being dispersed in the liquid, and it is expected to save the trouble of processing the stock and residue. it can.

  However, these stock packs containing the stock material of Patent Documents 1 to 3 can be stored and held for a long time in the state after opening the outer container in use. Oxidation occurs over time, and there is a problem that the flavor of the dashi stock is deteriorated, oxidation abnormalities, and quality decrease.

  On the other hand, conventionally, there has been a proposal for a flexible packaging bag for liquid filling that can suppress oxidation of the contents in the packaging bag even after opening. For example, Patent Documents 4 and 5 disclose a flexible packaging bag having a liquid dispensing nozzle made of a plastic film with a self-seal check function, that is, a film-like check nozzle. Since the flexible packaging bags disclosed in these documents are non-self-supporting packaging bags formed of a soft laminated film, it is inconvenient to use them alone as they are. Conventionally, it has been configured to be housed and fixed in a container as described in Patent Document 6.

Japanese Patent Publication No. 6-14842 Japanese Examined Patent Publication No. 7-95928 Japanese Patent No. 2595120 JP 2005-15029 A JP-A-2005-59958 JP 2004-196364 A

  In the flexible packaging bags disclosed in Patent Documents 4 and 5, liquid substances such as soy sauce and other liquid seasonings and salad oil are filled with liquid seal (also referred to as “liquid filling”: Japan Society of Mechanical Engineers 2005). 6.10 Lecture No. 05-47) (gasless filling), the bag is used as a liquid packaging body in which only the liquid or viscous packaging material is enclosed. Is. And the characteristic of the package of the full form formed by filling the flexible packaging bag with the liquid material (hereinafter referred to as “liquid material-packed package”) is the operation of pouring the liquid package from the bag body. No matter how many times it is repeated, there is no inflow (reverse flow) of the atmosphere, and at least in the bag body, the package is kept in a state where it is never exposed to the atmosphere. Therefore, since the liquid package to be packaged hermetically sealed in such a flexible packaging bag does not cause any chemical change such as oxidation, there is an advantage that it can be kept fresh as it is for a long time. .

However, for the flexible packaging bag, the film-like non-return nozzle is self-sealed by diffusion of intervening liquid due to capillary action between two front and back soft laminated plastic films (surface film and back film). In this case, the side of the packaging bag body is also in close contact with the film corresponding to the volume to be dispensed by the capillary action of the liquid package packed in the liquid seal. , Contracted or crushed and deformed. As a result, the liquid package in the packaging bag body may be obstructed by the strong adhesion between the front and back films as described above, and sometimes the smooth outflow may be obstructed. There is also a conflicting problem of inhibiting the check function described above.

  As described above, in the packaging bags disclosed in Patent Documents 4 and 5, when the packaged object is poured out by opening (opening) the nozzle, it is possible to prevent air from flowing in (inverse flow) instead. However, compared to the conventional liquid packaging containers, there is less deterioration in the quality of the packaged items, but if the usage is still bad, the nozzle check function described above may sometimes be weakened and air intrusion may not be suppressed. This may occur or, on the contrary, the non-return function is too strong, and smooth discharge of the liquid package may be hindered. Therefore, further improvements are required for this type of packaging bag (including nozzles).

  In addition, the conventional packaging structure shown in Patent Document 6 is a non-self-supporting flexible packaging bag filled and packaged with an article to be packaged, which is stored in a paper box. In this case, the packaging bag is stored in the box. There is a problem that the manufacturing process is complicated and expensive because the box structure is complicated, the burden of the boxing operation is large, and it cannot be automated.

Therefore, the present invention aims to solve the above-mentioned problems of the prior art, and in particular, a liquid material such as water or liquid soup and a filter bag enclosing an extraction material such as soup stock. In a double pack package that has been filled, it can maintain the fresh state of the initial filling stage for a long time without deteriorating the flavor of the seasoning liquid extracted from the dashi material. To propose a structure .

In addition, the present invention is suitable for co-filling of a liquid material such as water and a soup stock material, as well as a non-return function property and a pour-out property of a stock extract solution that is a packaged product (smoothly the seasoning liquid in the bag until the end) It is to propose a double pack packaging structure for seasoning liquid containing soup stock material, which is equipped with a film-like non-return nozzle which is excellent in that it can be poured out and at the same time not excessively discharged) .

Another object of the present invention maintains a soup material containing seasoning liquid for double pack packaging consisting mainly of amorphous having no flexible packaging bag in a non-self-supporting, so as to use form in a tabletop or the like as is It is to propose a double pack packaging structure for seasoning liquid containing dashi stock.

There is believed will provide a more favorable solution.

According to the double pack packaging structure for seasoning liquid containing broth material according to the present invention, a film having a self-sealing check function as a filter bag enclosing the broth material and a packaging bag for storing the liquid for extracting the broth material By using a flexible packaging bag with a non-return nozzle, it is possible to prevent the dashi material and the extract (the liquid material from which the dashi material component has been extracted) from being oxidized, and the quality and flavor, ie, taste, aroma, and taste After the package is opened and the extract is repeatedly poured out from the package, air does not enter the package. The flavor can be maintained.

Further, in the present invention, the pouring path inner surface of the film-shaped non-return nozzle, in particular excluding the portion serving as the base end side of the nozzle, by a wet process is performed in the portion of the opening scheduled position closer, a film-shaped non-return nozzle Even after opening and opening the packaging bag (opening the packaging bag) at the predetermined position, both the nozzle and the packaging bag body cause a backflow of air into the bag (air that flows in instead of pouring the packaged item). In addition, this reverse inflow is surely prevented, and the package contents (stock material and extract) in the bag can be kept in the original fresh state for a long time, and the extract can be always poured out smoothly. Become.

  Further, in the present invention, the discharge passage is formed by limiting the formation range of the wetting treatment to a range of 2/3 on the planned opening position side between the planned opening position and the nozzle base end side.

It is a front view of an embodiment which cuts out a part of the double pack package for seasoning liquid containing stock material concerning this invention, and clarifies the storing state of a filter bag. It is a partially cutaway perspective view of the double pack package for seasoning liquid containing the stock material of FIG. It is a front view which shows the formation range of the wetting process layer of a film-like non-return nozzle. It is an expanded sectional view of the opening planned position of a film-like check nozzle. It is a front view showing a reference example of a self-standing type of soup material containing liquid seasoning for double-pack packaging. It is a front view of the packaging structure formed by accommodating and holding the double pack package for the seasoning liquid containing the stock material in the outer packaging container.

The double pack packaged body for seasoning liquid containing the stock material according to the present invention is an outer large bag (hereinafter referred to as a flexible packaging bag), and a stock material stored in the flexible packaging bag together with water, soup stock, seasoning liquid, etc. It is composed of a double pack structure consisting of a combination with a water-permeable sachet (hereinafter referred to as a filter bag) enclosing (fish buns, dried fish, dried seaweeds, dried mushrooms, etc.).

  As the stock material used in the present invention, skipjack, soda bonito, tuna, mackerel, horse mackerel, sardine, saury and other fish fish, mackerel, horse mackerel, sardine, saury, flying fish, other fish boiled fish, clams, clams, red scallops , Oysters, scallops, other ingredients, dried shrimp, cherry shrimp, shrimp, red shrimp, krill, other shrimp, snow crab, king crab, crayfish and other shrimp , Other dry seaweeds, shiitake mushrooms, shimeji mushrooms, oyster mushrooms, matsutake mushrooms, sea cucumbers, mushrooms, mushrooms and other dry mushrooms.

  These dashi stock materials can be cut into pieces by cutting, cutting, crushing, crushing, or a combination of these as they are, roasting or drying as necessary, and then using only one kind or a combination of two or more kinds to filter Enclose in the bag. The stock material may be any material that contains at least a stock component, and may be one that has been once used for extraction, as well as unextracted material.

  In addition, this filter bag is a fine mesh bag that is excellent in drainage, pouring property, and does not leak easily, so that the ingredients of the soup stock are well extracted and diffused into the liquid such as water to be co-filled. Is used. For example, it is a laminate of paper nonwoven fabric and polyester mesh (Tea Road: registered trademark manufactured by Yamanaka Sangyo), etc., and there are no restrictions on the shape such as various bag shapes and box shapes. For example, in addition to a normal bag shape, a box shape or a tetrahedron shape may be used.

The material of the filter bag is preferably one that has a filter function that can retain insoluble solid content of the stock material that is stored, soluble proteins with a high molecular weight, tasteless substances, etc. in the filter bag. A woven fabric or a non-woven fabric made of pulp, cotton, hemp, silk, synthetic resin or the like alone or in combination can be used. In addition, depending on the type and quality of the stock material, a woven fabric made of metal such as aluminum or stainless steel, a film made of synthetic resin or metal, and a laminated film formed by laminating these, You may use the thin plate which directly thermoformed synthetic resin etc. so that it might have a micropore. In addition, this filter bag is used in which a dashi material is enclosed and the periphery is sealed by heat sealing, ultrasonic sealing, impulse sealing or simple stitching, and the thickness is 120 to 160 μm and the air permeability is 36. Those of about 0.0 to 50 cc / cm ² · sec are preferably used.

  Moreover, in this invention, water, a liquid stock, or another seasoning liquid is used as a liquid material co-filled in a flexible packaging bag with a stock material. Other seasonings are distinguished from liquid soup obtained only from water and soup stock, and consist of water and other food ingredients (excluding liquid soup) or water and liquid soup and other food ingredients. An aqueous solution or an aqueous emulsion. Therefore, salt, saccharides, extracts, protein hydrolysates, vinegar, soy sauce, miso, liquor, miso, thickener and dispersion emulsifier, pH adjuster, spices, fats and oils, other food materials alone or at least An aqueous solution or an aqueous emulsion containing them in combination can be used as a seasoning liquid.

On the other hand, the full Rekishiburu packaging bag, to the packaging bag body made of a laminated film of soft two-layer or three-layer, on top of one of the side edges thereof, and more preferably, softer than the bag body Two thin soft laminated plastic films with high flatness (front and back pair) face each other and face each other, and the liquid material is interposed in the pouring passage formed between these flat films, Film-like check nozzles (liquid dispensing nozzles as disclosed in JP-A-2005-59958), which are designed to exert a check function by capillary action, protrude to the respective side portions, diagonally upward directions, or top portions. It consists of what was heat-sealed and attached in the state made, or what was formed integrally with this packaging bag main body.

  The film-like non-return nozzle, which is a characteristic configuration of the flexible packaging bag, is, for example, a soft thin film (compared to the bag body) on the inner surface (sealant layer) of the upper side portion of the packaging bag body. With the sealant layer that is the outermost layer of the laminated plastic film facing each other, the sealant layer at the nozzle base end portion is fused and joined, and the dispensing passage provided in the nozzle and the inside of the packaging bag body are It is designed to communicate. For example, this nozzle is preferably made of two laminated plastic films formed by laminating a thermoplastic, uniaxial or biaxially stretched base film layer, and a sealant layer on both sides (inside and outside) sandwiching it. The base end portion of the sealant layers of the three-layer structure in which the sealant layers are opposed to each other as a pair of front and back, or the three-layer laminated plastic film in which a single laminated film is folded back in half width to form a pair of front and back surfaces A peripheral portion other than the outer peripheral portion is fused to each other to form a substantially wedge shape as a whole, and a pour-out passage in which the central portion is not fused is formed. However, it may have a two-layer structure in which the base films are impulse-sealed.

  Although this film-like check nozzle depends on the size of the flexible packaging bag, in general, when the packaging bag body is 100 to 150 mm wide and 150 to 200 mm long, the protrusion length X from the packaging bag body is X. The typical form is such that the nozzle width Y is about 30 to 80 mm and the nozzle width Y at the tip is about 20 to 40 mm.

  The flexible packaging bag body varies depending on the weight of the liquid to be filled, the soup stock, the seasoning liquid, and the weight of the filter bag to be stored (hereinafter also referred to as “packaged goods”). In the case of the self-standing type, in general, a thick two-layer laminated film having a waist of NY15 / PE60 is used, whereas the film-like non-return nozzle is not subjected to a load of an object to be packaged. It is preferable to use a thin three-layer laminated plastic film made of a combination of NY15 / PE20. The thinner the film, the better the check function, and the use of a weak film is better. In addition, a pair of front and back laminated plastic films having a higher flatness (flatness) can obtain a higher check effect, and the gap between the two front and back laminated plastic films during polymerization is about 10 to 300 μm. It is preferable to do so. However, this flatness is distinguished from the uneven structure showing the surface roughness described later, and is a form without large undulations and wrinkles over the entire film. The so-called uneven structure is the flat film. It is formed in small units.

  Such a film-like check nozzle is a sealant material used for the inner and outer surfaces (front material / backing material) of a pair of laminated plastic films between two overlapping (facing the front and back surfaces). For example, a thermoplastic resin film having a thickness of 5 to 80 μm, such as polyethylene, polypropylene, ionomer, EVA, or EVOH, and a heat seal material on the inner surface of the packaging bag body, for example, a sealant layer represented by polyethylene or polypropylene and a heat seal A film that can be used is used. Then, these sealant materials (films) are left in the inner edge portion so as to have a required shape (wedge shape), and the peripheral portion thereof is, for example, by heat sealing, high frequency sealing or impulse sealing, It can be manufactured by fusing.

  In addition, as a base film (support base material) sandwiched between the sealant materials of this film-like check nozzle, biaxially stretched films and uniaxially stretched films generally used for liquid packaging films such as nylon, polyester, polypropylene, EVOH, etc. Is used. Preferably, a uniaxially stretched film having excellent straight cut properties is used. In addition, these films include high barrier films (water vapor permeability) that have been vapor-deposited or coated with glass, alumina, silica, etc., in order to improve gas barrier properties in order to ensure long-term checkability. The use of a low one) is desirable because the adhesion effect due to the increase in the liquid concentration due to the evaporation of water vapor is improved and blocking of the nozzle can be prevented. The thickness is preferably, for example, 5 μm or more and 30 μm or less in order to maintain the flexibility of the film nozzle.

  A laminated plastic film having a structure of three layers (sealant layer [surface material] -base film layer-sealant layer [backing material]) manufactured as described above (however, two layers of a base film and a sealant layer) The film-like non-return nozzle comprising a structure) may be formed from a soft laminated film (mainly two layers) without causing the sealant layer, which is the outer surface of the base end portion thereof, to be fused between the inner surface side sealant layers. It is attached to the sealant layer (sealant layer made of the same kind of film) on the inner surface of the opening provided on one side of the packaging bag body by heat sealing and protruding from the packaging bag body. . Thereby, a flexible packaging bag provided with the film-like non-return nozzle which protruded outward from the upper part of the side part, the top part, etc. with respect to the packaging bag main body is obtained.

  By the way, in fusion-bonding the outer surface of the base end portion of the film-like check nozzle to the inner surface of the side opening portion of the packaging bag body, In order to prevent mutual fusion of the sealant layers, a release sheet having a higher melting point or not thermally fused is inserted inside the base end of the nozzle connected to the dispensing passage, or the inner and outer surfaces of the nozzle are respectively inserted. For example, the melting temperature of the sealant layer film on the outer surface of the nozzle is changed by the method of making the fusion temperature of the sealant layer different from each other, for example, by changing the material or by changing the extrusion lamination conditions, or the melting point of the sealant layer film on the inner surface of the nozzle. It is realized by making it higher.

  For example, the inner side [backing] sealant film is a thermoplastic resin such as polypropylene or polyethylene, and preferably has a melting point about 20 ° C. higher than the melting point of the outer side [surface], [ For the surface material, it is desirable to use a film that can be heat sealed at a temperature higher than the heat seal temperature of the sealant layer of the packaging bag body. These are necessary for preventing the sealant films on the inner surface of the film-like check nozzle from being heat-sealed when the film-like check nozzle and the bag body are fusion-bonded by heat sealing. The thickness is preferably 5 μm or more and 80 μm or less, for example, in order to maintain the flexibility of the film-like check nozzle.

The relationship between the film check nozzle and the packaging bag body is as described above. Is the thickness of the film check nozzle substantially the same as the thickness of the laminated film used for the packaging bag body? Rather, it is desirable to use a thin laminated film. However, it is possible to apply even in the opposite case.
For example,
(A) Film check nozzle: PE10 / PET9 / PE10 = 20 μm thickness, packaging bag body: PET12 / PE40 = 52 μm thickness (b) Film check nozzle: PE15 / PET12 / PE15 = 42 μm thickness, packaging bag Main body: PET12 / PE30 = 42 μm thickness (c) Film-like non-return nozzle: PE50 / PET25 / PE50 = 125 μm thickness, packaging bag main body: NY15 / PE30 = 45 μm thickness etc.
In the case where the laminated film has either a two-layer structure or a three-layer structure, each sealant layer is formed by subjecting the base film layer to a melt extrusion lamination method or a dry lamination method, an extrusion lamination method, a co-extrusion lamination method. It can be laminated by the method.

Here, in order to fill the packaging bag body with liquid materials such as water and liquid and seasoning liquid among the articles to be packaged , the film-like check nozzle is joined to the packaging bag body (heat seal). It is preferable to carry out it simultaneously with the process or after the joining process. For filling and packaging of such a liquid material, for example, filling is performed by a submerged sealing method (heat sealing of the film from above the filling liquid so that air, nitrogen gas, etc. are not mixed), or The gas is completely eliminated from the inside of the packaging bag body by, for example, evacuating the bag after filling the package. The reason is that, in order to cause the non-return action of the film-like non-return nozzle, it is necessary to perform sealing under the condition that the packaged material in the bag is sealed in the air and seal it. This is also necessary to prevent oxidation of the in-bag package.

  By the way, the filter bag is preferably heat-sealed at the time of vertical sealing of the packaging bag body and fixed in advance at a predetermined position (preferably the bottom of the packaging bag body) (can be stored in a free state) Next, it is preferable to perform the above-described seal filling in liquid such as water.

  The film structure of the packaging bag body of the flexible packaging bag according to the present invention is such that the base film layer located on the outer surface thereof and the sealant layer located on the inner and outer surfaces are respectively connected to that of the film check nozzle. The same kind of base film layer and sealant layer can be used. However, when the film-like check nozzle and the packaging bag main body are formed separately, an intermediate layer may be interposed between them, unlike the nozzle film. Preferably, the sealant layer forming the inner surface of the packaging bag body made of a soft laminated film is made of the same kind of resin material as the outermost sealant layer of the nozzle. According to this, the fusion-bonding strength of the packaging bag body of the nozzle can be sufficiently increased.

Then, as the capsule Sobukuro body, preferably constituted by laminated films of two-layer or three-layer structure, a uniaxial or biaxially oriented base film layer of the laminated film, polyethyleneterephthalate having a thickness of 8~30μm phthalate film A layer (PET layer), a nylon resin film layer (NY layer), ethylene vinyl alcohol (EVOH), or the like is preferable. Further, the sealant layer of the laminated film used for the packaging bag body may be constituted by an unstretched PE layer or PP layer having a thickness of 10 to 60 μm, an EVA layer, an ionomer layer, an EVOH layer, or the like.

  By the way, when the thickness of the base film layer is less than 8 μm, water vapor impermeability, gas barrier properties and the like may be insufficient. On the other hand, when the thickness exceeds 30 μm, the bending strength of the laminated film is large. Therefore, the adhesiveness of the inner surface of the nozzle after the stoppage of the packaged article may be impaired. Moreover, about the sealant layer, when the thickness is less than 10 μm, there is a possibility that sufficient sealing strength cannot be secured, and when it exceeds 60 μm, the bending strength of the laminated film may be excessively increased. As long as this thickness is compensated in total, each sealant layer can be composed of two or more films.

As the laminated film used in the packaging bag body, since It was one Determination of liquid material and the need for accommodating a material containing filter bags, having a strong stiffness is required. In the present invention, the bending strength per unit width (15 mm) of the laminated film, in other words, the waist is measured with a waist measuring device (mini bear (as shown in FIG. 10 of JP-A-2005-59958). It is preferable that the value measured using a load cell (UL-100GR) is 40 to 300 mN. Koshido In less than 40 mN, the hitting the pouring of the packed material from the flexible packaging bag, in addition to the stability of the output direction, such as poor it Note, not denied waist weak feeling of the packaging bag body, the flexible packaging bag There is a risk that the strength deficiency of itself will become apparent. On the other hand, if it exceeds 300 mN, the entire check function including the film check nozzle may be lowered regardless of the laminated structure of the laminated film.

  Extracted liquid obtained by extracting the raw material into the liquid to be packaged (liquid + filter bag) filled (liquid) and stored (filter bag) in the flexible packaging bag of the present invention having the above-described configuration. (Hereinafter simply referred to as “extracted liquid”) is poured out by cutting off a predetermined opening portion specified by the addition of a tear guide rod or notch formed near the tip of the film check nozzle and opening the nozzle. By doing. Then, after opening the nozzle, the double pack package for the seasoning liquid containing the dashi material is tilted so that the nozzle opening (pouring spout) is oriented downward, and the packaged product, particularly the extraction liquid, is extruded. Easily achieved by pressure. In this case, the film-like non-return nozzle made of a soft laminated plastic film is a laminated plastic on the front and back sides by the action of the water head pressure of the article to be packaged (extracted liquid) or pressurizing the body of the package with fingers. The films swell and separate from each other, and at the same time, the pouring passage is formed for the first time, and at the same time, the nozzle opening is also opened, and the packaged material (extracted liquid) is poured out.

  When extracting the extract, which is one of the items to be packaged, through the nozzle opening (pour spout) of the film-like check nozzle, the packaging bag body made of a soft laminated film is used for dispensing the extract. Nevertheless, because of the non-return function of the film-like non-return nozzle, there is no suction (back flow) of outside air, so the packaging bag body is shrunk or reduced sequentially by an amount corresponding to the volume of the pour. It will be crushed and deformed.

  In the double pack package for the seasoning liquid containing the stock material in the state of co-filling the liquid material and the stock material in the flexible packaging bag constituted by the packaging bag body formed by protruding the film-like check nozzle, the above-mentioned As described above, by tilting this, only the required amount of the extraction liquid can be poured out from the inside of the packaging bag. However, when the packaging body is returned to the original standing posture, the extraction from the nozzle opening is performed. Liquid outflow stops. Due to the stoppage of the outflow, the liquid extraction liquid always remains (stays) in the pouring passage of the film check nozzle due to the capillary action and becomes wet. Therefore, at the same time as the stop, the inner surfaces of the laminated films are strongly adhered to each other by capillary action, and the nozzle openings are also kept in close contact, thereby reliably preventing the outside air from entering the packaging bag body. become. Therefore, in a flexible packaging bag having such a film-like check nozzle, the packaged material filled in the bag is in contact with the outside air not only before but also during and after the dispensing. It will be in the state of an anaerobic atmosphere which is completely cut off from and protected, and oxidation, contamination, etc. of the beverage in the bag will be effectively prevented.

In the present invention, in order to ensure the close contact between the inner surfaces of the laminated plastic film by the capillary action, the surface wettability is improved with respect to the laminated plastic film, thereby improving the above-described check function. It is preferable to make it . That is, the self-sealing check that is exhibited when the liquid package remains in the passage by the capillary action on the inner surface of the dispensing passage provided in the film-like check nozzle, that is, the inner surface of the sealant layer. In order to make the function more reliable, a wetting treatment layer obtained by performing the following wetting treatment is provided on the inner surface of the pouring passage of such a film check nozzle.

As the wetting treatment, the surface of the film surface of the laminated film made of a film having a particularly low polarity and low activity such as PE or PP is applied to the surface of the film by a physical method, a chemical method, or a mechanical method. to increase the activity, for example in a physical way, corona discharge treatment, UV ozone treatment, resin coating treatment, metal deposition treatment, electroless plating treatment, metal cold spraying process, a plasma etching process, wet consisting flame treatment By applying the treatment, a method is adopted in which the surface tension is improved by physical surface modification of the film surface and surface modification by generation of polar functional groups, thereby improving the wettability of the film. In addition, this treatment may be a method of treating the film surface with an acid or alkali as defined in JIS K6843-3: 1999, or a mechanical method such as mat processing.

  For example, among the physical wetting processes described above, the corona discharge process refers to the surface of the sample passing between the dielectric and the electrode by generating a corona by applying a high frequency and high voltage between the dielectric and the insulated electrode. Is a method of processing. The mechanism for modifying the surface is considered as follows. That is, the oxygen present in the air is activated by the generated corona, and this oxygen cuts and enters the film molecular chain to generate polar groups (C═O, COOH, C—OH, etc.) and strong. Unevenness is generated on the sample surface by collision of electron energy. As a result, the surface strength and adhesiveness of the film are improved.

Therefore, the inventors experimented on a typical corona discharge for the action effect of the wetting treatment layer. Table 1 shows the results. That is, for a film-like check nozzle having a three-layer structure of LLDPE15 / PET12 / LLDPE20, corona discharge treatment (discharge condition: discharge amount = 81.7 W · min / m) on the inner surface (LLDPE) of the sealant film. ² ) was performed. When the wetting tension of the film was measured with a wetting reagent, the film was 32 N / m before treatment and 56 N / m after treatment, and the contact angle with water is as shown in Table 1. The cohesive force of the liquid, that is, the surface tension (S) was weakened, and in all cases, the contact angle (θ) was clearly reduced to improve the wettability of the film, and the effectiveness of this treatment was confirmed.

  However, while the wetting treatment ensures the adhesion between the laminated plastic films, if the effect is too strong, the filled liquid package is tilted to form a film. If you try to pour out again through the check nozzle and there is a sufficient amount of liquid (liquid height) in the bag body (when the head pressure is high), smooth pour out is possible. However, when the amount of liquid in the bag decreases, the water head pressure decreases, and the pouring pressure loses the adhesive force due to the capillary action between the laminated plastic films, preventing smooth pouring and liquid return. Become so.

  Therefore, in the present invention, the adhesion force between the laminated plastic films based on the capillary action of the film check nozzle is slightly relaxed, and the discharge passage is always secured, that is, the check function of the film check nozzle is maintained. In order to reduce the adhesion between the films, the wetting layer 11 is not the entire inner surface of the film check nozzle 1 but the nozzle base edge 1c as shown by the oblique lines in FIG. It is preferable to provide it only in the part near the nozzle opening planned position 1a, and more preferably between the part from the nozzle opening planned position 1a to the base end side 1c (L). It is provided on the inner surface of only the 2/3 (2 / 3L) portion on the planned opening position side.

  Thereby, with the improvement of the adhesive force between the laminated plastic films of the film check nozzle, the adhesive force is moderated moderately. In other words, as a range where the wetting process is performed, by excluding the part serving as the nozzle base end side and the vicinity thereof, it is possible to always pour the packaged article smoothly, and the wetting process layer is close to the planned opening position. Since it is provided, the article to be packaged interposed at the tip of the nozzle opening after the end of discharge returns so as to be sucked into the wet treatment layer on the inside thereof, so that dripping can be effectively prevented.

  Further, the wetting layer is preferably a portion of 2/3 or less, more preferably 1/2 or less of the planned opening position side of the film-like check nozzle from the planned opening position 1a to the base end side 1c. Provided. This is because when the wetting treatment layer exceeds the above range (over 2/3), the adhesive force between the laminated plastic films becomes too strong, and the packaged object is opened at the nozzle tip when the discharge pressure becomes small. It is because there is a possibility that it cannot be poured out smoothly.

  In addition, the non-return function (adhesion force between films) of the film-like non-return nozzle is greatly influenced not only by the wettability of the laminated plastic film constituting the nozzle but also by the wettability of the package (extracted liquid). . Therefore, it is preferable to determine the formation range of the wetting treatment layer depending on the type of the object to be packaged. For example, in the case of an object to be packaged that has a high salt content and high wettability, the base end side is the nozzle opening planned position. In the case of an article to be packaged having a low salinity and low wettability, 2/3 from the nozzle opening planned position to the base end side or the planned opening position It is preferable to set the range of the vicinity position excluding the portion serving as the nozzle base end side.

  Further, as a method of slightly relaxing the adhesion between the laminated plastic films based on the capillary action of the film-like check nozzle and always ensuring smooth pouring, it is shown on the inner surface of at least one of the packaging bag body as shown in FIG. A vertical stripe processing, embossing, and blast processing as shown in Fig. 5 are applied to a plane shape, island shape, and stripe shape to give a straight or curved concavo-convex structure 14, and the capillary action particularly in the packaging bag body 2 portion. May be weakened. In addition, the uneven structure 14 is given to the portions excluding the respective seals (horizontal seal, vertical seal, joint seal between the nozzle and the main body, and the peripheral seal of the nozzle) on the front and back laminated plastic films. The reason for excluding the seal portion is that if there are irregularities in the seal portion, a seal failure will occur.

  The concavo-convex structure 14 added to the laminated film has a gap between the laminated films on the front and back of the packaging bag main body 2 (excluding vertical seal, horizontal seal, and a bonded seal portion between the nozzle and the main body), that is, the thickness of the liquid layer. In general, the adhesive force based on the capillary action described above is generated at about 2 to 5 μm, but one or both of the laminated films are embossed, for example, and the gap between the films is 20 μm or more, preferably 30 μm or more. More preferably, concavities and convexities are provided so as to be 50 μm or more. In this case, the capillary action is reduced, resulting in a decrease in the adhesion between the laminated films. As a result, at least for the portion where the uneven structure 14 is given as a partial pattern or a full-surface pattern, the flow path is always secured, even when the amount of liquid in the bag is extremely reduced. As a result, it is ensured that the liquid package is always smoothly poured out.

  The above uneven processing is preferably processing that gives an irregular pattern in addition to a regular pattern using an embossing roll (Japanese Patent Laid-Open No. 2008-12669) having an uneven pattern such as a cylinder or a prism. Further, in place of such embossing, random wrinkling, blasting, knurling, vertical and horizontal striped processing may be performed. These are preferably combined in such a way that the uneven positions are shifted and a constant gap of about 20 to 50 μm is formed. For example, in a bag making machine, a hot roll (70 to 80 ° C.) is formed before bag making (before vertical sealing) or after bag making.

The inventors filled the packaging bag body 2 having a laminated film structure of tech barrier NY15 vapor deposition surface / vapor deposition surface tech barrier PET12 / XA-HD40 with an underwater seal, An experiment was conducted to measure the remaining amount when the liquid stopped flowing. As a result, as shown in Table 2, it was found that the effect was remarkable when a laminated plastic film subjected to unevenness processing was used. In addition, in this experiment, as shown in FIG. 1, the case which put the vertical stripe pattern 14 by embossing in the film-like non-return nozzle 1 vicinity of this packaging bag main body 2 and the packaging bag main body which has not performed uneven | corrugated processing, Compared. As a result, it was found that in the example suitable for the present invention, the remaining amount is small, it can be used up to the end, and the pouring can be performed smoothly.

Et al is, the adoption of the convex-concave structure, while smooth pouring of the filled liquid packed material can be secured, this may lead to unintended excess runoff. Therefore, in the present invention, the film-like non-return nozzle has a liquid reservoir portion 1b for dispensing amount control as shown in FIG. 1 and FIG. It becomes a more preferable embodiment to provide.

  By adopting such a liquid reservoir 1b, the extraction liquid (of the raw material component) guided from the packaging bag body 2 to the extraction passage of the film-like check nozzle 1 is temporarily retained in the liquid reservoir, Since the discharge flow rate is generally lowered and the discharge flow is directed to the slit opening, the excessive outflow can be avoided. For this purpose, it can be said that it is also effective to provide a protrusion (formed by a seal) as a damming portion at the top and / or bottom of the inlet of the extraction passage 13 at the base end of the check nozzle.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a double pack package 8 for a seasoning liquid containing broth material according to the present invention , and FIG. 2 is a perspective view thereof. This double pack package 8 is an example in which a film-like non-return nozzle 1 for pouring out a liquid article to be packaged is provided on, for example, the upper left edge of a packaging bag body 2 made of a soft laminated film. The sealant layer on the inner surface side of the joint portion of the packaging bag body 2 is made of the same outer layer sealant layer as the base end portion of the film check nozzle 1, preferably the same kind of resin material as the sealant layer of the packaging bag body 2. The resulting sealant layers are superposed and heat sealed and fusion bonded. In some cases, the sealant film on the inner surface of the spout passage 13 of these fusion bonded portions is made of a high melting point, and this portion is melted at a low temperature so that the bonding strength is weak (by pressing the body portion of the bag body). It is possible to form a temporary sealing portion 12 that is easily peeled off by applying an internal pressure and passes between the nozzle and the main body.

  Here, as the film-like check nozzle 1, a thermoplastic base film layer, for example, a biaxially stretched PET layer or NY layer having a thickness of 5 to 40 μm, preferably 10 to 30 μm, and both sides of the base film layer are used. Each of the sealant layers laminated on each other, for example, a layer composed of three layers of an unstretched PE layer or a PP layer having a thickness of 5 to 80 μm, preferably 10 to 50 μm, can be exemplified. For example, a laminated plastic film disposed on each side of the front and back, that is, a laminated plastic film of two front and back sides having the same contour shape or the like, or a single laminated plastic film folded back on the front and back at the center Are formed in a bag shape by fusing each other as shown by hatching in FIG. 1 at each side portion excluding the base end side, preferably by heat sealing, with the inner surface side sealant layers facing each other. To do.

  Such a film-like non-return nozzle 1 is shown in FIG. 4 in an enlarged cross-sectional view taken along line II-II in the nozzle width direction of FIG. 4 is a three-layer structure of a base film layer 5, 5 ′ and respective sealant layers 6, 6 ′, 7, 7 ′ laminated on both sides of the base film layer 5, 5 ′. The inner surface side sealant layers 6 and 6 'are preferably disposed over a predetermined width, for example, a width of 0.5 to 3 mm, preferably 1.0 to 2.0 mm, in a peripheral portion excluding the base end side. Can be easily and quickly manufactured by heat sealing and fusing to a desired shape (wedge shape).

  In order to provide a check function, it is preferable that the film-like check nozzle 1 is flattened by stacking as flat sheets as possible. At the nozzle base end, the outer surface side sealant layers 7 and 7 'are fused to the inner surface (sealant layer) of the packaging bag body 2 preferably by heat sealing, so that the packaging bag body 2 In addition, it can be joined properly, reliably and easily.

  As shown in FIGS. 2 and 5, the outer surface of the film check nozzle 1, that is, the outer surface from the planned opening position 1 a to the base end side 1 c of the outer surface side sealant layers 7, 7 ′ It is preferable to provide a water-repellent or oil-repellent coating layer (water-repellent or oil-repellent coating layer) 10 for preventing and improving liquid breakage along at least the opening end and the lower edge.

  As the water repellent material, a water repellent coating agent made of silicone oil, fluorine resin, acrylic resin or amide resin is used. As the oil repellent material, silicon resin or Teflon resin (Teflon: US DuPont registered trademark), Using oil-repellent coating agents such as silicone-modified acrylic resins, urethane, acrylic, ester, nitrified cotton, amide, vinyl chloride, rubber, styrene, olefin, vinyl chloride, cellulose, A phenolic resin or the like is added as a binder.

  Further, as shown in FIG. 2, the film check nozzle 1 is provided with a spire-shaped protrusion 18 for preventing dripping at a position slightly closer to the base side 1c side than the opening position 1a of the lower edge portion thereof. Preferably, the protrusion 18 is provided in order to prevent dripping generated from the opening end of the film check nozzle 1 from being transferred from the lower edge of the film check nozzle 1 to the packaging bag body 2. It has been. And it is preferable to provide the water-repellent or oil-repellent coating layer 10 on the protrusion 18 for preventing dripping.

Moreover, as a specific structure of the film-like check nozzle 1 according to the present invention , as shown in the cross-sectional view of FIG. 4, the surfaces of the inner surface side sealant layers 6 and 6 ′ of the film-like check nozzle 1, particularly, It is preferable that the inner surface of the portion where the extraction passage 13 is formed be a corona discharge treatment or the like to provide a wettability-enhanced surface 11 and a wet treatment layer 11, thereby effectively exerting an outer check function. be able to.

  In particular, in the present invention, the wetting layer 11 is provided on the inner surface of the extraction passage 13 at a portion near the planned opening position 1a except for the base end side 1c and the vicinity thereof. In particular, the wetting layer 11 is formed. As shown by hatching in FIG. 3, the range is provided in a range (2 / 3L) between the planned opening position 1a and the base end side 1c (L) and 2/3 on the planned opening position 1a side (2 / 3L). It is preferable, thereby, the self-sealing check function can be effectively exhibited, and the close adhesion between the plastic films of the film check nozzle 1 can be relaxed and the packaged articles can be discharged smoothly all the time. In addition, about the formation range of this wetting process layer 11, it is preferable to consider the kind of to-be-packaged object, ie, the wettability of a to-be-packaged object, within the said range.

The non-return nozzle 1 configured as described above is provided at the same time as filling the liquid packaging material in the liquid packaging material 2 into the packaging bag body made of a laminated film or prior to filling the liquid packaging material in the liquid seal. For example, the sealant layers 7 and 7 ′ on the outer surface of the base end of the nozzle 1 are preferably formed on the inner surface of the packaging bag body 2 at the fusion part between the sealant layers on the side of the packaging bag body 2. It becomes a part of the flexible packaging bag by fusion-bonding by heat sealing.

  Such a flexible packaging bag, as illustrated in FIGS. 1 and 2, contains a large amount of liquid material W such as water, which is one of the objects to be packaged therein, and a filter bag containing material M. Together with F, it becomes a double pack package 8 for the seasoning liquid containing the soup stock, which takes a full form by filling with a seal in the liquid, preferably under evacuation. However, the double-pack package 8 for the seasoning liquid containing the stock material shown in the figure is a non-self-supporting type, and therefore is shown in FIG. 6 for the transportation, storage, display, use, etc. It is housed and used in an outer packaging container 9 having a self-supporting dispensing function as described in detail. That is, the outer packaging container 9 is preferably a so-called standing pouch P made of a soft laminated film, for example, in addition to a plastic hard container including paper. By this standing pouch P, the double-pack package 8 for the seasoning liquid containing the stock material is provided with self-supporting property and regularity, and can be used as it is on a desktop or the like.

Furthermore, it to materials containing liquid seasoning for double pack package, as shown as a reference example in FIG. 5, the lower end portion of the packaging Sobukuro body 2 of soup material containing seasoning liquid for double pack package 8 ', ship bottom shaped The bottom 16 may be fused and joined by heat sealing or the like to give the flexible packaging bag itself a self-supporting property. In this case, it is not necessary to store the double-pack package 8 ′ for the seasoning liquid containing broth material in the outer packaging container 9 as shown in FIG. 6, and it can be used as it is. In the case of such a double-pack package 8 ′ for a seasoning liquid containing a stand-alone soup stock material, the laminated plastic film constituting the packaging bag body 2 has a thickness or waist that is self-supporting and formable. It is necessary to use a highly laminated film, the thickness of the base film layer is 50 to 250 μm, preferably 80 to 180 μm, the thickness of the sealant layer is 10 to 60 μm, preferably 10 to 30 μm, and the stiffness is about 40 to 300 mN. It is preferable to do.

Further, in the case of the self-supporting seasoning liquid-containing double pack package 8 ′ shown in FIG. 5, both corners of the bottom portion are chamfered so that the bottom portion has a gently curved shape with a downward convexity. It is preferable that both corners of the bottom do not come into contact with the floor surface, and the entire lower end of the double pack package 8 ′ is attached to the floor surface, so that the double pack package 8 ′ is self-supporting. A stable standing can be secured.

In addition, it is preferable to chamfer both corners of the bottom of the ship bottom shape of the double pack packaging body 8 ' for broth material containing seasoning so that the radius of curvature R is 8 mm or more, and more preferably in the range of 8 to 20 mm. . In particular, the radius of curvature R is preferably formed so as to gradually decrease toward the bottom. The reason why the radius of curvature R is 8 mm or more is that if it is less than 8 mm, both corners of the bottom of the ship bottom shape come into contact with the floor surface, and the center part of the double-pack packaging body 8 ′ for seasoning liquid containing broth material will float. Because.

However, hitting the use of engaging Rudas material containing seasoning liquid for double pack package 8 to the present invention, prior SL film-like non-return nozzle 1 is removed or excised tear the tip side of the aperture scheduled position 1a nozzle Tilt the standing pouch P, which is the outer packaging container 9, with the liquid packaging material (extracted water) in the double pack packaging body 8 for the seasoning liquid containing the stock material in a state where the opening, i.e., the spout is secured. In such a posture, the film-like check nozzle 1 is poured out without intruding or inhaling outside air from the spout provided in the nozzle. On the other hand, when the pouring is stopped based on the standing and returning of the standing pouch P, the inner surface of the film-like non-return nozzle is intervened with a liquid film to be packaged that wets the inner surface, that is, a liquid film composed of the pouring region. Below, this is made to adhere | attach over the whole and the penetration | invasion of the outside air into this packaging bag main body 2 is prevented reliably.

  According to this, the packaging bag body 2 is filled with a liquid material such as water in a liquid seal, and the filter bag F in which the stock material M is sealed is co-filled, and the double pack for the seasoning liquid containing the stock material In the package 8, the extract of the raw material component can be poured out without any intake of outside air into the packaging bag body 2 under contraction or crushing deformation corresponding to the amount to be poured out. Then, after stopping the pouring, the non-intrusion of the outside air into the packaging bag body 2 is prevented by a close sealing by the non-return function of the inner surface of the pouring passage 13 of the film-like non-return nozzle 1, thereby Oxidation of the stock material and the extract remaining in the bag body 2 by the outside air is surely prevented.

  After the required amount of the extraction liquid has been poured out, the standing pouch P, which is the outer packaging container 9, is returned to the upright position to stop the pouring, and at the same time, the leading end of the film-like check nozzle 1 is stopped. It provides automatic close and close of the spout provided.

  Here, the close contact due to this check function of the film check nozzle 1 is the same as described above, when the film check nozzle 1 is released from the hydraulic head pressure, 4 is restored to the original shape at the time of manufacture of the film check nozzle 1, and the plastic films 3 and 4 on the front and back are decompressed when the extract in the film check nozzle 1 is returned to the packaging bag body 2. By placing in the atmosphere, the inner surface of each of the soft films (sealant layers 6 and 6 ') is subjected to the entire width of the nozzle 1 with the intervention of the capillary action of the liquid material that is the extract that adheres to this surface. This is performed by, for example, being negatively adsorbed to each other. Further, the close contact between the films based on such a self-seal check function is more reliable when the packaging bag body 2 that has been crushed and deformed tends to depressurize the inside of the packaging bag body 2 based on the inherent elastic restoring force. Will be maintained.

In the present invention, as described above, as the inner surface of the packaging bag main body 2 exhibits a concave-convex structure 14, hot pressing and facilities Succoth preferably after bag-making or during bag-making laminated film 3, this to ensure smooth flow as a whole of the liquid packed material I by the relaxation of the capillary action under liquid inclusions between the laminated films each other caused by, so that can be easily poured out to the last.

  On the other hand, this may lead to excessive pouring of the liquid package from the nozzle 1, and in order to prevent this, in the present invention, as shown in FIG. 1 and FIG. 1 is provided adjacent to the base end side 1c side (packaging bag main body 2 side), and a dispensing amount control liquid reservoir 1b that swells downward is provided so that the discharge flow is temporarily retained in this zone. It is a preferred embodiment to prevent excessive pouring and to provide stable metered dispensing.

  Furthermore, in the present invention, in conjunction with the formation of the liquid reservoir 1b, more preferably, as shown in FIG. 2, the sealing portion (temporary sealing portion) of the base end portion of the dispensing passage 13 of the film check nozzle 1 is used. 12), a damming portion 17 for the purpose of rectifying the pouring flow may be provided so that a constant amount of discharge can be realized at all times.

Incidentally, the film-like non-return nozzle 1 used in the present invention, its base end portion, the side of the packaging Sobukuro body 2, many, in projecting position from the side upper end portion, the outer surface low By using a high-melting film as the melting point sealant layer, and fusion-bonding with the high-melting point sealant layer on the inner surface of the packaging bag body 2, the sealant layer at the base end portion of the film check nozzle 1 is used, for example, It is good also as the temporary sealing part 12 made into the state fuse | melted by the relatively low temperature with the adhesive strength of half or less of original heat seal intensity | strength.

  By adopting the temporary sealing portion 12, for example, even when the filled article to be packed is heated to 50 to 100 ° C. and a required extraction component is extracted, the film-like check nozzle 1 In addition, it is possible to sufficiently protect most of the extraction passage of the extract from permanent deformation in the direction in which the extraction passage is inflated, and at the same time, until the check nozzle 1 is opened (cutting off the tip). The package bag main body 2 exhibits an effect of temporarily preventing the article to be packaged from inadvertently entering the dispensing passage 13 of the check nozzle 1.

Therefore, the film-shaped non-return nozzle 1, the portion of the tip side of the temporarily sealed portion 12 (the so-called nozzle pouring path 13), it is possible to sufficiently exhibit the functions of the film-shaped non-return nozzle 1, out It is possible to completely prevent the outside air from entering the packaging bag body 2 when the extract is poured out from the double-pack package 8 for the seasoning liquid containing raw material . Moreover, the self-seal check function at the time of stopping the pouring of the article to be packaged can be sufficiently exhibited.

By the way, when the packaged item in the packaging bag body 2 is cooled to near normal temperature , the double-pack packaged body 8 for the condiment material-containing seasoning liquid is poured out from the packaging bag body 2 of the packaged product. In addition, for example, a load (pressure) is applied in the thickness direction to open the temporary sealing portion 12, and the tip portion of the film-like check nozzle is broken or cut off to form a dispensing opening, In this state, the double pack packaging body 8 for broth containing seasoning liquid is tilted so that the pouring posture is such that the pouring opening faces downward.

The heat sealing strength of the temporary sealing portion 12 is 0.3 to 3 (N / 15 mm), particularly 0.7 to 1 (N / 15 mm). While preventing the unsealing, it is preferable to open the temporary sealing portion intentionally without affecting the other fusion bonded portions.
That is, if it is less than 0.3 (N / 15 mm), there is a possibility that unintentional opening may occur in the temporary sealing portion 12 under the relationship with the volume of the bag in the heated liquid package, On the other hand, if it exceeds 3 (N / 15 mm), the load required to open the temporary sealing part 12 may have an unexpected influence (bag breaking or opening) on other fusion bonded parts or the like. .

  The load for opening the temporary sealing portion 12 should be in the range of 50 to 350 (N), particularly 100 to 200 (N), leading to breakage of bags at other locations including the sealing portion. However, it is necessary to prevent accidental opening during transportation and work. If the opening load is less than 50 (N), there is a possibility that the temporary sealing portion may be opened in the lower packaging body due to the stacking of the packaging bodies filled and packaged with the article to be packaged. On the contrary, 350 (N) This is because, when the temperature exceeds 60 degrees or the heat seal strength is too high, other fusion-bonded portions may be affected by the load required to open the temporary sealing portion.

According to the study of the present inventors, for example, on the side upper portion of the package bag body 2 (NY15 / PET12 / LLDPE40) soft, the base end portion of the film-shaped non-return nozzle 1 as shown in FIG. 1, a low temperature The laminated structure of such a film-like non-return nozzle film is a linear low density polyethylene layer (low melting point sealant layer) / biaxially stretched polyethylene terephthalate layer / A temporary low-density polyethylene layer (high melting point sealant layer) is formed, and this laminated film is heated and pressed at a cylinder pressure of 300 kPa for 3 seconds by a heat sealer with a cylinder using a heat sheet temperature as a parameter, and a temporary sealing portion 12 The heat seal strength (N / 15 mm) was measured with a tensile tester (TENSILON RTG-1300) at a tensile speed of 200 mm / min. Measurement was performed under the condition of a rumm width of 15 mm. The results are shown in Table 3.

  As a method of fixing the filter bag F in the packaging bag main body 2 described above or storing it without fixing, the filter bag F is simply loaded in the packaging bag main body 2 and then liquid such as water is sealed in the liquid. A method of filling, a method of filling the packaging bag body 2 with the filter bag F, degassing and filling with a liquid material and then heat sealing, attaching the filter bag F to a predetermined position of the film by impulse sealing, etc. Fill the liquid with vertical / horizontal sealing, and then fill the liquid with a seal, or attach the filter bag F in advance to the specified position on the film, degas by vertical / horizontal sealing, and fill with liquid Depending on the method of heat sealing.

In the present invention, the packaging bag body 2 made of a soft laminated film, for example, in a non-self-supporting flexible packaging bag in which the film-like check nozzle 1 protrudes at the position of the upper side portion thereof, In order to help the self-supporting of the double-pack package 8 for the non-independent dashi material-containing seasoning liquid containing the liquid bag and the dashi material-containing filter bag F, the following self-supporting cylindrical dispensing function is provided. An outer packaging container 9 of a mold, for example, a bag-like container such as a standing pouch P, is provided, and an extraction liquid / dashi stock filling packaging structure that accommodates and holds this is proposed.

And as this outer packaging container 9, it is substantially the same shape as the said film-like non-return nozzle 1 in the one edge part used as the position corresponding to the said film-like non-return nozzle 1, for example, the upper part of a side edge part like the example of illustration. A standing pouch P or the like protruding from the overhanging sachet 15 surrounding the nozzle is preferably used. The outer packaging container 9 is a packaging material having a flexible material, for example, a plastic, paper, or metal dispenser function (a function of pressurizing the packaging bag body portion to pour out an article to be packaged). May be.

The outer packaging container 9 with the dispenser function, preferably, the top portion, as shown in FIG. 6, the packaging bag body upper portion of the non-self-supporting for soup material containing seasoning liquid for double pack package 8 accommodating Heat sealed together, or the top of which can be opened and closed with a chuck or the like, or the top is embossed and sealed to the main body, and the double pack package 8 is stored in a replaceable manner, etc. It is preferable that the outer packaging container 9 can be replaced.

The present invention is thus to the combination of both free-standing outer packaging container 9, the preferred embodiment the non-self-contained soup material containing seasoning liquid for double pack package 8 and standing port Uchi P described above, however the material containing seasoning liquid for A double pack packaging structure is obtained.

It is heat-sealed and fused together over a part (spot) or the entire width of the upper side, and stored in a suspended state. In such a case, the double pack package 8 filled with the liquid can be held firmly in the standing pouch P and has an effect of assisting the smooth outflow of the liquid package. . In addition, in this case, it becomes possible to sufficiently protect against various impacts during handling or distribution of the double pack package 8 for the soup stock containing seasoning liquid, and for the seasoning liquid containing the soup stock material . It is possible to prevent the double pack package 8 from being displaced, and to prevent the occurrence of pinholes and the like, the deformation and breakage of the film check nozzle, and the erroneous opening.

  In addition, after storing the soup stock containing seasoning double pack package 8 in the standing pouch P, one or more locations in the vicinity of the film-like check nozzle 1, particularly near or above the bottom, or at the top of the packaging bag body 2 or Fixing two or more locations, and further the bottom, is effective for effective operation when all the extract is smoothly poured out to the end.

The role of the outer packaging container 9 described above is to hold the double-pack packaging body 8 for the seasoning liquid containing the stock material contained therein, and to extract the material filled in the flexible packaging bag with a submerged seal. In order to extrude the liquid material (extracted liquid), the flexible packaging bag is pressed, and the extracted liquid is transferred from the packaging bag body 2 to the film check nozzle 1 part with the help of the uneven structure 14 described above. That is, it has a so-called dispenser function for smoothly feeding and discharging. In the present invention Therefore, by elastic deformation has the above-described flexible, outer packaging container 9 having a dispenser server functions are effectively used.

About the double pack packaging body for seasoning liquid containing seasoning liquid (invention example) that constitutes the double pack packaging structure for seasoning liquid containing broth material according to the present invention , it is allowed to stand at room temperature for 8 weeks with the film-shaped check nozzle opened. In the meantime, the following sensory test was carried out on the taste, aroma and color of the extract. In addition, as a comparative example, the same sensory test was implemented and compared for the package formed by filling the soy sauce prepared by extracting the raw material into a normal flexible packaging bag (without a film-like check nozzle).

The production conditions of the packaging bodies of the present invention and comparative examples were as follows.
<Conformity example of the present invention>
After 3g of coarse bonito crushed material and 1g of kelp crushed material are enclosed in a filter bag made of polyester spunbonded nonwoven fabric (manufactured by Daiki Shoji Co., Ltd.) and stored in a flexible packaging bag. Then, 300 ml of 3 times thick soup prepared without using a dashi in the packaging bag was hot-filled at a temperature of 85 ° C. to prepare a double pack package conforming to the present invention.
<Comparative example>
In 300 ml of soy sauce, 3 g of thick soy sauce extracted with 3 g of bonito coarsely crushed product and 1 g of kelp crushed product and added to the inside, in a normal flexible packaging bag (without film check nozzle) The package was heat-filled at 85 ° C. and a package as a comparative example was produced.
In addition, both the packaging bodies of the conformity example of the present invention and the comparative example were made of a laminated plastic film made of transparent vapor deposited NY15 / transparent vapor deposited PET / LLDPE40. In addition, as the thick soy sauce, 90 ml of soy sauce, 45 g of sugar, 30 ml of mirin, and salt were added to adjust the salt content to 10.5% per 300 ml of soy sauce.

  The packaging bodies according to the present invention and the comparative example produced as described above were opened and left in that state for 8 weeks at room temperature (temperature 11 to 24 ° C., humidity 44 to 80%). Table 4 shows the results of a sensory test on the taste, aroma and color of the packaged product (extract) during that time. In addition, this sensory test was carried out by five panelists using a product to be packaged diluted three times with ion-exchanged water.

  As a result, in the example of conformity with the present invention, since the dashi material is directly enclosed in the packaging bag through the filter bag, the dashi fragrance is strong and spreads. In addition, over time, the scent of the dashi is slightly weakened, but the sweetness is maintained, and the check function of the film check nozzle prevents the oxygen from entering the bag. Oxidation could be prevented. On the other hand, in the comparative example, the scent of dashi is weak from the beginning, and after 6 weeks, the color becomes slightly darker and the sweetness does not appear. After 8 weeks, the packaged material is oxidized due to the penetration of oxygen into the bag. As a result, the color changed to darker and a weak oxidizing odor was generated.

  The technology of the present invention is not limited to a double pack package for a seasoning liquid containing a stock material provided with a film-like check nozzle, but also a general liquid-filled package, in particular, a general formed integrally with a packaging bag body. The present invention can also be applied to a packaging structure containing a refillable soft packaging bag having a liquid spout.
