  The present invention relates to a cooking pouch used for cooking contents stored in a storage unit.

  The cooking pouch stores contents in its storage section and is used for cooking the stored contents. 2. Description of the Related Art A cooking pouch is known in which a zipper tape is provided near an upper opening of a pouch main body (for example, see Patent Document 1). According to such a cooking pouch, for example, it can be used for cooking as follows.

  A powder containing mainly flour is stored in the storage section, and the pouch for cooking is sold in a state where the powder is mainly sealed with a zipper tape and the upper part outside the zipper tape is heat-sealed. The cook opens the outer portion of the zipper tape, further opens the zipper tape, and then introduces additional materials, such as liquids, eggs, and ingredients, into the container through the upper opening and the zipper tape. Thereafter, the cook closes the zipper tape and mixes the powder and the additional material in the container. Thereafter, the cook opens the zipper tape again, and discharges the mixed material to the outside of the cooking pouch through the upper opening and the zipper tape. In this way, the cook can mix the ingredients using the cooking pouch (one mode of cooking).

The left direction is indicated by D21, the right direction is indicated by D22, and both directions are collectively referred to as "lateral direction D2". When the configuration of the cooking pouch 1 is described, unless otherwise specified, the description will be made based on the state (posture) when the bottom of the pouch main body is turned down. When the bottom of the pouch main body is set to the lower side, the direction from the bottom of the pouch main body to the top and the direction from the top of the pouch main body to the bottom correspond to the upward direction D11 and the downward direction D12, respectively. Similarly, when the bottom of the pouch main body is on the lower side, the direction from one side to the other side of the pouch main body coincides with the lateral direction D2.

〔Contents〕
The pouch main body 2 includes a storage section 26 that stores various materials as contents. The contents accommodated in the accommodation section 26 are not particularly limited. Examples of the contents include powders (including granules), liquids, food materials having fluidity, and chopped food materials. The contents are roughly divided into a first material and a second material. The first material is stored in the storage section 26 in advance by the manufacturer at the time of sale of the product, or when the cooker who has obtained the cooking pouch 1 with the storage section 26 empty is stored in the storage section of the cooking pouch 1. 26. The second material is a material that is further introduced by the cooker via the opened chuck tape 7 into the storage portion 26 in which the first material is stored.

  In the present invention, “cooking” is widely interpreted, and is not limited to cooking to the state of being served (also referred to as “complete cooking”), but also cooking to just before the state of being served (additional cooking is required). When necessary, also referred to as "semi-finished cooking"). Cooking involves simple mixing. Mixing includes rubbing, shaking, crushing, and other actions that result in mixing.

"Mixing" (mixing) is a process in which water, eggs, meat, vegetables, and other ingredients are added to a container containing powder and liquid seasonings in advance, and the contents are mixed after the container is sealed. That means.
"Kneading" refers to mixing and kneading or pushing the contents together with the container after sealing the container. “Shake” refers to mixing the contents by shaking the container up, down, left, right, etc., after sealing the container.

  As the first material in the semi-finished cooking, for example, a so-called “premix” (abbreviation of Prepared Mix, pre-mix), flour (light flour), strong flour, and tempura flour are exemplified. Premix is an adjusted powder that can be easily cooked for cakes and breads, etc. Suitable for flour and other flours (including starch), sugars, fats, milk powder, egg powder, leavening agents, salt, flavors, etc. as necessary. It is blended in. Premixes include hot cake mix, okonomiyaki mix, bread mix, cookie mix, and monjayaki mix. Examples of ingredients for omelets include ham, fresh cream, cut vegetables, semi-cooked vegetables, and frozen vegetables.

  The first ingredient in semi-finished cooking or finished cooking includes health foods such as prepared foods, protein (powder), amino acids (powder), green juice (powder), diet foods, dried fruits, cereals, fruits, nuts, Examples include confectionery, desserts, other processed foods, and various powders for meal replacement. In addition, powdered coffee, sports drinks, and other powdered drinks can be used.

  As the second material, for example, liquid materials such as milk, soy milk, juice, coffee, tea, water, etc., liquid food materials such as eggs, cheese, chocolate, etc., chopped or melted food materials having liquidity Powders such as baking powder, salt, sugars and spices, various liquid seasonings, yeasts such as yeast, and ice.

  In the completed cooking, frozen confectionery such as ice confectionery (such as sherbet-like ice) and ice cream as the first material, and beverage liquid such as milk and syrup as the second material are mixed to produce a frozen confection. Beverage can be easily prepared.

  The cooking pouch of the present invention is suitable for a case where a mixed material such as a cake or an omelet contains a large amount of air and is softly baked. It is also suitable for mixing beverages such as coffee by whipping.

  In addition, in the case of being poured into a ply pan or a bowl or the like in semi-finished cooking and then additional cooking is performed, a spout portion having a structure formed of a film integrated with the pouch body 2 as in the first embodiment (details) Is described later).

(Pouch body)
The structure of the pouch main body 2 will be described in more detail. As shown in FIGS. 1 and 2, the pouch body 2 is formed of a heat-flexible film. The film forming the pouch body 2 includes a front film 21 forming a front surface, a back film 22 forming a back surface, and a bottom film 23 forming a gusset of the bottom portion 32. That is, the pouch body 2 has a bottom gusset pouch shape having a gusset on the bottom 32. In other words, the pouch body 2 has a front surface formed by the front film 21, a back surface formed by the back film 22, and a bottom surface formed by the gusset of the bottom 32. The cooking pouch 1 functions as a standing pouch having autonomy.

  In the first embodiment, the front film 21 and the back film 22 are formed of substantially rectangular films except for the region of the spout 6. The substantially rectangular shape is not limited to a geometrical rectangular shape, but includes a shape that is recognized as a rectangular shape in the whole. For example, any one or more of the side edge, bottom edge, or top edge may include a curved portion. Further, the corners of the film may be rounded in the shape of a convex arc.

  The gusset part is provided on the bottom part 32 of the pouch main body 2. When the contents are stored in the storage part 26, the gusset part is sufficiently widened, so that the cooking pouch 1 can stand alone. Further, since the gusset portion is widened, the capacity of the accommodation portion 26 can be increased as compared with the case of a flat pouch having no gusset portion at the bottom. On the other hand, when the contents are not stored in the storage portion 26, the bottom film 23 forming the gusset portion can be folded back so that the folded portion 35 is formed on the upper portion. Thereby, the entire thickness of the pouch main body 2 is reduced.

  The front film 21, the rear film 22, and the bottom film 23 may be separate films from each other before the pouch body 2 is formed, or may be integrated films. In the case of an integral film, any two or more of the front film 21, the rear film 22, and the bottom film 23 may be integral. The integral film is folded to form any two or more of the front film 21, the back film 22, and the bottom film 23.

  In the upper part 31 of the pouch body 2, the upper part of the front film 21 and the upper part of the back film 22 are joined. Examples of the joining means include heat welding (heat sealing) and ultrasonic welding (the same applies hereinafter). By this joining, as shown in FIG. 2, an upper seal portion 41 is formed on the upper portion 31 of the pouch body 2 as a seal portion for joining the upper portion of the front film 21 and the upper portion of the back film 22.

  In addition, when the cooking pouch is sold in a state where the contents are not accommodated, the upper seal portion 41 may not be provided. The upper seal portion 41 is formed after the content is stored in the storage portion 26. However, in FIG. 2, the formation of the upper seal portion 41 is performed in a state where the content is not stored in the storage portion 26. The planned area is indicated by two-dot chain line hatching. The present invention includes both cooking pouches in which the contents are not stored and cooking pouches in which the contents are stored.

  At the side 33 of the pouch body 2, the side of the front film 21 and the side of the back film 22 are joined. By this joining, the left and right side portions 33 (the left side portion 331 and the right side portion 332) of the pouch main body 2 serve as side seals for joining the side portions of the front film 21 and the back film 22 to each other. The part 43 (left seal part 431, right seal part 432) is formed. In addition, the gusset part is not provided in the side part 33 of the pouch main body 2.

  If the cooking pouch 1 is symmetrical on the front and back, the distinction between left and right is relative and convenient. In addition, when it is not necessary to distinguish between the left side portion 331 and the right side portion 332, and a common explanation is given, it is simply expressed as "side portion 33".

  At the bottom 32 of the pouch main body 2, the lower peripheral edge of the front film 21 and the peripheral edge of the front half of the bottom film 23 are joined, and the lower peripheral edge of the rear film 22 and the rear half of the bottom film 23 are joined. Are joined. Thus, the bottom seal portion 42 is formed on the bottom 32 of the pouch main body 2. Since the width of the bottom seal portion 42 is relatively wide, air bubbles are relatively easily generated in the bottom seal portion 42 during the sealing process. Therefore, when the bottom seal portion 42 is formed, it is preferable to suppress bubbles by using a hot plate provided with air holes.

  A cutout portion 231 is provided on a side portion of the bottom film 23. The side of the front film 21 and the side of the back film 22 are basically not joined because the bottom film 23 other than the cutout 231 is interposed therebetween. However, at the notch 231, the side of the front film 21 and the side of the back film 22 directly contact each other. Therefore, the front film 21 and the back film 22 are joined by the side seal 43 at the notch 231. Thereby, the independence of the standing pouch is improved. In the vertical direction D1, only one notch 231 may be provided (in FIG. 1, the number of the notch 231 is one), but the number of the notches 231 is two or more (for example, two) in the vertical direction. It may be provided.

(Outlet)
The spout 6 is a part for pouring out the contents stored in the pouch main body 2. The cooking pouch 1 according to the first embodiment includes a pouch main body 2 having an accommodating portion 26, and a spout 6 integrally connected to the pouch main body 2. The spout 6 is formed integrally (with the same material) with the front film 21 and the back film 22 of the pouch body 2. The entire spout 6 </ b> A is composed of a front film 21 and a back film 22 that are common to the pouch body 2. Specifically, between the film 21 and the back film 22, a flow passage 60 through which the content F0 flows when the content F0 (see FIGS. 4 and 5) stored in the storage portion 26 is poured out. (See FIG. 2) is formed.

  From another point of view, the pouch body 2 and the spout 6 are integrally formed at least at a portion where they are connected. Specifically, at the portion where the pouch body 2 and the spout 6 are connected, both the pouch body 2 and the spout 6 are constituted by the front film 21 and the back film 22.

The pouring direction D6 of the spout 6 is substantially parallel to the direction D7 in which the chuck tape 7 extends. More specifically, the spout 6 faces in the lateral direction D2 when the bottom 32 of the pouch main body 2 faces downward in a front view. In the first embodiment, the pouring direction D6 of the spout 6 is a sideways direction (lateral direction D2). The direction D7 in which the chuck tape 7 extends is also the lateral direction D2. The term "substantially parallel" means not only the case of being strictly parallel, but also, for example, the extending directions may differ by about ± 5%.
The pouring direction D6 of the spout 6 is not limited to the lateral direction D2, but in consideration of operability, the lateral direction D2 is preferable in a front view.

  As shown in FIG. 3, the spout 6 includes a flow passage 60, a spout seal 67 surrounding the flow passage 60, a knob 64, an opening line 66, and a scheduled opening portion 68.

  The flow passage 60 is formed between the front film 21 and the back film 22 and protrudes from the pouch main body 2 in the left direction D21. When the contents F0 housed in the housing part 26 is poured out. This is a passage through which the content F0 flows. The flow passage 60 is gradually tapered toward the left direction D21 in a front view.

  The spout seal portion 67 is a seal portion surrounding the flow passage 60 except for the first connection portion 51 to which the pouch body 2 and the spout portion 6 are connected. More specifically, in the spout 6, a side edge portion arranged with the bisector L1 interposed therebetween and a tip portion where the bisector L1 intersects are thermally welded. The spout seal portion 67 is a heat-welded portion at the side edge portion and the front end portion of the spout portion 6. The bisector L1 of the spout 6 is a line connecting the center of the base of the spout 6 and the center of the tip of the spout 6 in a front view.

  The knob portion 64 is a portion that can be pinched with a finger when opening the spout 6. The opening line 66 forms a boundary between the spout seal portion 67 and the knob portion 64. The opening scheduled portion 68 is a scheduled opening to be a spout (opening) through which the contents are poured out by opening.

  When the opening line 66 is broken and the spout 6 is broken along the breaking direction, the opening scheduled portion 68 is also broken toward the spout seal 67 on the opposite side across the bisector L1. Thereby, the opening of the spout 6 is formed. FIG. 5B shows the spout 6 opened by the opening line 66.

  The opening line 66 is formed in the front film 21 and the back film 22 in order to facilitate the operation of forming the opening of the spout 6 by breaking the spout 6. Specifically, the opening wire 66 is processed so that the cooking pouch 1 is more easily broken than other portions. A perforation is illustrated as an example of the processing.

  The opening section 68 may be provided with an easy-opening means for making it easier to open the cooking pouch. For example, the opening scheduled portion 68 may include an easy opening line such as a half-cut line formed by laser processing, a cutter, or the like. In this case, a plurality of easy-open lines extending substantially parallel to each other may be provided. A stretched film may be included in the laminated films constituting the front film 21 and the back film 22, and the stretching direction of the stretched film may be made to coincide with the direction in which the opening portion 68 extends. Further, the opening-scheduled portion 68 may not be provided with a particularly easy-opening means. The opening portion 68 may be torn by hand or cut with scissors. An indication to indicate to the user that it is an opening place may be provided in the opening scheduled portion 68 by printing or the like.

[Relative position of spout port to pouch body]
The position of the spout 6 relative to the pouch body 2 will be described. When the bottom 32 of the pouch main body 2 faces downward, the first connection portion 51 (see FIG. 3) where the pouch main body 2 and the spout 6 are connected to each other has a vertical direction D1 of the pouch main body 2 when viewed from the front. 25 to 75% of the position. FIG. 2 shows that the lower end of the pouch main body 2 is 0% and the upper end of the pouch main body 2 is 100% in the vertical direction of the pouch main body 2.
The length K51 (see FIG. 3) of the first connection portion 51 in the vertical direction D1 is, for example, not less than 30 mm and not more than 80 mm.

[Length ratio of housing portion 26 and flow passage 60]
The ratio of the length of the housing portion 26 to the length of the flow passage 60 will be described. When the bottom portion 32 of the pouch main body 2 is set to the lower side, the housing portion 26 and the flow path 60 are connected to the length K26 (see FIG. 1) of the housing portion 26 in the vertical direction D1 when viewed from the front. The ratio (K52 / K26) of the length K52 of the connection portion 52 (see FIG. 3) is 15 to 35%.
The length K52 (in the vertical direction D1) of the second connection portion 52 is, for example, not less than 20 mm and not more than 70 mm. The upper end of the length K26 of the housing portion 26 in the vertical direction D1 is the chuck tape 7.

[Chuck tape]
Next, the chuck tape 7 will be described in detail. As shown in FIGS. 1 and 2, the chuck tape 7 is a member provided to reclose the pouch body 2 after being broken and opened along the easy opening means such as the notch 73. The chuck tape 7 extends from at least one end of the housing portion 26 to the other end. In the first embodiment, the direction in which the chuck tape 7 extends is the lateral direction D2.

  The chuck tape 7 includes a male member 71 provided on the inner surface of one of the front film 21 and the rear film 22, and the other of the front film 21 and the rear film 22 facing the male member 71. (See FIG. 4 (B)). The male member 71 and the female member 72 are configured to be fittable with each other. By releasing the engagement between the male member 71 and the female member 72, the chuck tape 7 can be opened, and the material can be introduced into the container 26 via the chuck tape 7. Further, by fitting the male member 71 and the female member 72, the accommodating portion 26 of the pouch main body 2 after the chuck tape 7 is opened can be closed again. The phrase "via the chuck tape 7" means "through an opening formed between the male member 71 and the female member 72, which have been disengaged and separated."

The chuck tape 7 has a configuration that can be opened and closed at least once, and in actual use, it is preferable that the opening and closing can be performed a plurality of times. It is preferable that the zipper tape 7 can secure watertightness at the time of closing in practical use.
The configuration of the known technique can be used for the chuck tape 7. For example, the configuration of the chuck tape described in JP-A-2005-231693 can be used.
The chuck tape 7 is provided at least from one end to the other end of the storage section 26. Functionally, it is sufficient that the chuck tape 7 is provided in this range, but in terms of production efficiency, in the first embodiment, the chuck tape 7 is provided from one end to the other end of the pouch main body 2 (accommodating portion). 26, from the one end to the other end, and further to the side edge of the pouch body 2.)

  The chuck tape 7 may have a shape retaining property. Specifically, when the zipper tape 7 is opened, each of the male member 71 and the female member 72 of the zipper tape 7 swells convexly in the front-rear direction, and has a shape retaining property in which the swelled shape is held. ing. As the chuck tape 7 having shape retention, for example, a technique described in JP-A-2011-246188 can be used. Since the chuck tape 7 has a shape retaining property, it is possible to facilitate the operation when the first material or the second material is charged.

  The front film 21 and the back film 22 between the upper seal part 41 and the chuck tape 7 are provided with easy-open means (described later). In the first embodiment, the easy-opening means comprises notches 73 provided on the left and right side portions 33 (side seal portions 43) of the pouch body 2 respectively.

  The introduction direction D5 of the material into the storage portion 26 in a state where the chuck tape 7 is opened is not limited, but in consideration of operability, when the bottom of the pouch main body is set to the lower side, when the bottom of the pouch main body is set to the lower side, the pouch main body is directly downward to horizontal. The orientation between them is preferred. In the first embodiment, the introduction direction D5 is a downward direction D12 when viewed from the front.

  The cross-sectional area of the opening of the spout 6 is much smaller than the cross-sectional area of the opening of the chuck tape 7, for example, 1/10 or less, preferably 1/20 or less.

(Transparency of accommodation section)
The accommodation section 26 may have transparency at least in part. The transparent portion (not shown) is used, for example, to confirm the amount of the content stored in the storage unit 26. The accommodation section 26 may have transparency as a whole. Further, only a partial area of the pouch body 2 may have transparency. Marks (not shown) and scales (not shown) may be provided on the portion having transparency. This makes it easy to visually recognize the amount and the degree of mixing of the contents.

  Further, for example, only the central region in the lateral direction D2 of the housing portion 26 has transparency, and the outer portion of the transparent portion in the lateral direction D2 is opaque by printing or the like, and various displays are applied to the opaque portion. It may be. This is because, when a mark or a scale is used, if the contents around the mark or the scale can be visually recognized, the function is often sufficient. In the case of a form in which a plurality of cooking pouches are packed and sold, the display may be omitted, and the whole or almost the whole may be a transparent cooking pouch.

〔the film〕
The film as a packaging material includes at least a base material layer and a sealant layer. The film as a packaging material may further include another layer. Examples of the other layers include a printing layer, a gas barrier layer for preventing permeation of oxygen gas and water vapor, a light-shielding layer for imparting light-shielding properties, and a support for imparting mechanical strength.
As a material constituting the base layer, plastics such as polyethylene terephthalate, nylon, and polypropylene, paper, and the like can be used. Further, as a material constituting the sealant layer, polyethylene, polypropylene, or the like can be used. The laminated film may include a plurality of base layers, or the sealant layer may include a plurality of layers.

The printing layer includes a printed display for indicating product information or giving aesthetic appearance to the bag. Examples of the print display include letters, numbers, symbols, figures, and patterns.
Examples of the support include a stretched polyester film such as a stretched polyethylene terephthalate film, a stretched polyamide film such as a stretched nylon film, and a stretched polyolefin film such as a stretched polypropylene film.
Examples of the gas barrier layer include a metal foil such as an aluminum foil and a vapor deposition layer. The vapor deposition layer may be provided on the base material layer, the sealant layer, or the support.
The deposited layer may be a metal deposited layer made of a deposited layer of a metal such as aluminum, or may be a transparent deposited layer made of a deposited layer of an inorganic oxide such as aluminum oxide or silicon oxide.

  A gas barrier coating film may be provided on the deposition layer. The gas barrier coating film is a coating film that functions as a layer that suppresses transmission of oxygen gas, water vapor, and the like. The gas barrier coating film has a general formula R1nM (OR2) m (where R1 and R2 represent an organic group having 1 to 8 carbon atoms, M represents a metal atom, and n represents an integer of 0 or more. And m represents an integer of 1 or more, and n + m represents the valence of M.) and at least one alkoxide represented by the following formula: and a polyvinyl alcohol-based resin and / or ethylene-vinyl alcohol. It is obtained by a gas barrier composition containing a polymer and being polycondensed by a sol-gel method in the presence of a sol-gel method catalyst, an acid, water, and an organic solvent.

[Appropriate physical properties of the pouch body for cooking methods]
For cooking “kneading”, the pouch body 2 made of a film having low stiffness (rigidity) is preferable. This is because, when rubbing the pouch body 2 with bare hands, if the seal portion is hard or the bent portion of the film is sharp, the hand is likely to be injured. Also, it is easy for the cook to directly obtain the feeling of mixing the contents. Further, the pouch body 2 having a relatively high piercing strength is preferable. This is because it is difficult to break when rubbing.
For cooking “shake”, the pouch body 2 made of a high-strength film is preferable. This is because the content moves inside the housing portion 26, and the film is less likely to be bent every time the content moves. Further, the pouch body 2 having high piercing strength is preferable. This is because it is difficult to break when shaking.

Specifically, preferred ranges of the stiffness (rigidity) and the piercing strength of the pouch main body are as follows.

〔Example of use〕
Next, an example of a usage example of the cooking pouch 1 according to the first embodiment will be described with reference to FIGS. FIGS. 4 and 5 are diagrams sequentially illustrating the use procedure of the first embodiment.

[Step of Exposing Chuck Tape for Cooking Pouch Containing First Material]
The accommodating portion 26 of the cooking pouch 1 accommodates, for example, the powder F1 as the first material. Further, the opening of the pouch body 2 is not closed by the easy opening means 73, and the upper part of the pouch main body 2 is closed by the upper seal part 41 and the chuck tape 7.
From this state, as shown in FIG. 4A, the portion between the upper seal portion 41 and the chuck tape 7 is broken in the lateral direction D2 by using the easy-opening means 73, and the upper part of the pouch main body 2 is opened. Is released to expose the chuck tape 7.

[Step of opening zipper tape]
Next, as shown in FIG. 4 (B), with respect to the chuck tape 7, the fitted male member 71 and female member 72 are released, and the male member 71 and the female member 72 Is separated. As a result, the male member 71 and the female member 72 each have a shape bulging convexly in the front-rear direction. An opening through which the additional material can pass is formed between the male member 71 and the female member 72. Note that if the chuck tape 7 has a shape retaining property, the opening shape is maintained without holding the chuck tape 7 by hand or the like.

[Step of introducing the second material via the chuck tape]
Next, as shown in FIG. 4C, for example, eggs F2 and liquid F3 as the second material are introduced into the storage section 26 via the chuck tape 7.
