Description

  The present invention relates to a bag-in-box inner bag storage container, a bag-in box, and a method for handling the bag-in-box inner bag.

  Conventionally, a bag in box (Bag In Box) is generally composed of a flexible inner bag and an outer container made of corrugated cardboard. It is used for transporting fluid contents such as granular materials or powders. This type of bag-in-box generally has a capacity of about 1 to 20 liters and is excellent in handleability and disposal after use. However, at the manufacturing site of food, pharmaceuticals, and various industrial products that need to be manufactured in a clean environment, paper dust generated from corrugated cardboard can cause foreign matter. May be used.

However, the outside of the can may become dirty during transportation or storage, and cleaning may be required before being brought into a clean environment. In addition, since the contents are directly stored, disposal and cleaning (when reused) are required after use, which is disadvantageous in terms of cost. In some cases, the inner bag is taken out from the bag-in-box and only the inner bag is carried into a clean environment. Whether it is taken out, carried around at the time of carry-in, stored or taken out, it is troublesome. For this reason, a bag-in-box in which the outer container is a rigid container made of a synthetic resin has been proposed (see, for example, Patent Documents 1 to 3).
Japanese Patent Laid-Open No. 10-278935 JP 2000-272661 A JP 2004-99073 A

However, if there is no portion for fixing the spout as in the container described in Patent Document 1, the position of the spout is difficult to determine, which is inconvenient to use as it is.
When an opening from which the spout can be taken out is provided in a part of the lid like the container described in Patent Document 2, in order to take out the contents from the spout, it is necessary to lay the container on its side so that the spout is sideways. There is. For this reason, the connection between the main body container and the lid is made strong, and when the inner bag is stored in the main body container and the lid is closed, it is necessary to work hard so that the lid will not be opened carelessly. And takes time. Moreover, when a flexible inner bag is used, the position of the spout may change before the opening provided in the lid is opened, and the spout may not be drawn out from the opening.

  When a main body container having a hole in the side surface is used like the container described in Patent Document 3, the spout can be protruded laterally from this hole. However, when storing the inner bag after filling the contents with an undefined shape and weight in the main body container, the inner bag is easily deformed by its own weight, and the rigid main body container is like a cardboard box, Since it is impossible to correct the position of the spout by inserting a hand into the stored inner bag, it is difficult to reach the spout near the hole. Furthermore, even if the spout can reach the vicinity of the hole, it takes time to put a finger into the hole and pull out the spout. Moreover, if the main body container is opaque, it will take a lot of trouble because it will look for the spout from the hole.

  The present invention has been made in view of the above circumstances, and it is easy to store an inner bag having a spout, and is excellent in handleability, and a bag-in box using the same It is an object to provide a method for handling an inner bag for a bag-in-box.

In order to solve the above-mentioned problems, the present invention is provided on the side surface of a bottomed main body container having an open top, a notch extending downward from the upper opening of the main body container, and a lower end of the notch. And a notch-shaped spout receiving part for receiving the spout of the bag-in-box inner bag, the cut-out part maintaining the posture in which the tip end of the spout protrudes outside the main body container. The spout has a width that allows the spout to be freely moved up and down within the notch, and a spout stop projection is provided at the boundary between the cutout and the spout receiving part. The spout stopping protrusion engages with the upper part of the spout when reaching the outlet receiving portion, thereby preventing the spout received in the spout receiving portion from being lifted to the notch portion side. An inner bag storage container for bag-in-box is provided.
The inner bag storage container for bag-in-box can include a lid that covers the upper opening of the main body container.

The present invention also provides a bag-in-box for a side wall of a bottomed main body container having an open top, a notch extending downward from the upper opening of the main body container, and a lower end of the notch. A notch-shaped spout receiving part for receiving the spout of the inner bag, and the notch is formed so that the tip of the spout protrudes to the outside of the main body container while maintaining the posture. A spout stop piece extending downward is provided at the edge of the lid that covers the upper opening of the main body container. A bag-in-box characterized in that the spout received in the spout receiving part can be prevented from being lifted to the notch part by sometimes contacting the upper end of the spout with the lower end of the spout restricting piece. An inner bag storage container is provided.
The spout stop piece can be inserted into the inside of the main body container when the lid is closed, and both side edges of the spout stop piece can contact the inner surface of the main body container at both side edges of the notch. It is preferable.

In the above-described inner bag storage container for bag-in-box, the storage container can be made of synthetic resin.
Further, the present invention is a bag-in-box in which an inner bag for bag-in-box is stored in the above-described inner bag storage container for bag-in-box, wherein a tip end portion of the spout is passed through the spout receiving portion. Provided is a bag-in-box that is exposed to the outside of a container.
In this bag-in-box, the bag body of the inner bag for bag-in-box is preferably a film-type flexible packaging bag formed by heat-sealing a film.
The inner bag for bag-in-box preferably has a handle.

The present invention also relates to a method for handling an inner bag for a bag-in-box that is used in an environment where paper dust is disliked, and the inner bag for a bag-in-box that has been transported in a transport container made mainly of paperboard. Is taken out from the transport container before the environment that dislikes paper dust, stored in the above-mentioned inner bag storage container for bag-in-box, and then used in the state where it is carried in the environment dislikes paper dust and stored in the storage container. Provided is a method for handling an inner bag for a bag-in-box.
In this bag-in-box inner bag handling method, it is preferable that the transport container has an easy tearing means including a perforation and / or a cut tape on a side surface.

According to the bag-in-box inner bag storage container of the present invention, when the bag-in-box inner bag is stored in the main body container, the tip of the spout is protruded to the outside of the main body container with the spout facing sideways. While maintaining the posture, the spout can easily reach the spout receiving part through the notch extending downward from the upper opening.
Furthermore, when the spout restricting projection is provided at the lower end of the notch, the spout restricting projection engages with the upper portion of the spout when the spout reaches the spout receiving portion. The upward movement is restrained. When the spout stop piece extends downward on the edge of the lid body, the bottom end of the spout stop piece abuts on the top of the spout when the lid is closed, and the spout moves upward. Is stopped. In either case, the spout is easily set in the spout receiving part without hiding the spout inside the main body container or attaching a separate spout fixing member. be able to. Then, the upward movement of the spout can be stopped and the spout can be securely fixed to the spout receiving part. For this reason, it is easy to store the inner bag, and since the spout is exposed to the outside of the container with the inner bag stored in the storage container, it is convenient for taking out the contents of the inner bag.

If there is a spout stop piece that can be inserted inside the main body container when the lid is closed, and both side edges of the spout stop piece can contact the inner surface of the main body container at both side edges of the notch, Since the box inner bag can be pressed from the outside, it is possible to reliably prevent the inner bag from being deformed and protruding from the notch to the outside.
By providing the lid that covers the upper opening, foreign matter can be prevented from entering the main body container. Moreover, when stacking a plurality of storage containers vertically, another storage container can be easily placed on the lid.
When the storage container is made of a synthetic resin, it can be molded at a low cost, and there is no concern about the occurrence of paper dust or rust, which is reasonable.

According to the bag-in-box in which the bag-in-box inner bag is stored in the bag-in-box inner bag storage container of the present invention, and the tip end of the spout is exposed to the outside of the main body container through the spout receiving part. Therefore, the contents can be taken out from the inner bag with the lid placed on the opening of the main body container. For this reason, after carrying in a bag-in-box to a work site, the change of the positional relationship of the top | upper surface and side surface of a bag-in-box becomes unnecessary, and it can install quickly in the destination. In addition, since it is not necessary to firmly connect the storage container and the lid body, the storage container itself can have a simple structure, and complicated work is required when the inner bag is stored in the storage container and the lid body is closed. Will not occur and the time and effort can be reduced.
When the bag-in-box inner bag is a film-type flexible packaging bag formed by heat-sealing a film, the bag-in-box inner bag storage container of the present invention can be effectively applied. As a result, the volume can be easily reduced by taking out all the contents from the inner bag and then folding or rounding, and the workability and disposal of the collection are excellent.

According to the method for handling an inner bag for a bag-in-box of the present invention, the following excellent effects can be obtained.
(1) Cost can be reduced by using a normal transport container made mainly of paperboard.
(2) The bag-in-box inner bag is generated from the transport container by taking it out of the transport container before carrying it in an environment that dislikes paper dust and storing it in the bag-in-box inner bag storage container of the present invention. It is possible to prevent contamination of the work environment due to paper dust and dust adhering to the transport container.
(3) The storage container is taken out of a clean work site that dislikes paper dust only when the inner bag is transferred from the transport container, but since it is installed in a clean environment for most of the time, it is contaminated by external foreign matter. The possibility of is extremely small. For this reason, even when the inner bag is transferred to the storage container and carried into the work site, no time-consuming washing such as washing with water is necessary, and if necessary, it can be completed in a short time, such as blowing clean air. By simply performing such a process, it is possible to obtain a clean state that can be carried into the work site.
(4) Since the inner bag for the bag-in-box can be handled as it is stored in the storage container, it is easy to handle at the time of carry-in, and the posture of the spout is kept constant regardless of the remaining amount of contents. Therefore, it is easy to take out the contents. In addition, it is easy to replace the inner bag when taking out the empty inner bag from the storage container and replacing it with the inner bag containing the new content after use of the content is completed, and store it when the inner bag is replaced Cleaning the container can be omitted.

When a bag having a handle is used as an inner bag for a bag-in-box, it becomes easier to hold when transferring from a transport container to a storage container, and the working time can be shortened.
When a container with easy tearing means consisting of perforations and / or cut tape on the side is used as the transport container, the transport container can be opened widely, and the inner bag for the bag-in-box can be easily taken out You can save time.

First, an inner bag storage container for a bag-in-box according to the present invention will be described.
1 and 2 are views showing a first embodiment of an inner bag storage container for a bag-in-box according to the present invention, and FIG. 1 (a) is an exploded perspective view showing a part of a lid cut out. 1 (b) is a perspective view, FIG. 1 (c) is a cross-sectional view taken along line AA of FIG. 1 (b), and FIG. 2 is a front view.
An inner bag storage container for bag-in-box (sometimes simply referred to as “storage container”) 10A shown in these drawings includes a main body container 11 and a lid body 12, and has a bag main body 3 and a spout 4 inside. By storing a bag-in-box inner bag (hereinafter, simply referred to as “inner bag”) 2, the bag-in-box 1 </ b> A can be configured. In FIG. 2, the position in which the inner bag is stored is indicated by a two-dot chain line. Usually, a cap, a cap combined cock or a dedicated cock is attached to the tip of the spout. In FIG. 1 and FIG. 2, they are omitted.

  As shown in FIG. 1, the main body container 11 is a bottomed container having an upper opening portion 11a, and has a substantially rectangular bottom portion 11b and four side surface portions 11c, 11d, 11e, and 11f provided therearound. Have On one side surface portion 11c of the main body container 11, a notch portion 13 extending downward from the upper opening portion 11a and a notch-shaped spout receiving portion 14 connected to the lower end of the notch portion 13 are formed. Yes. The lid body 12 has a plate-like main body portion 12 a and a rib-like peripheral wall portion 12 b erected around the main body portion 12 a, and the lid body 12 is formed on the periphery of the upper opening portion 11 a of the main body container 11. When the peripheral wall portion 12b is fitted, the main body container 11 and the lid body 12 are integrated to close the upper opening portion 11a. The main body container 11 and / or the lid 12 may be provided with engaging means such as hinges and locking claws, and opening prevention means such as a pin and a buckle, and a predetermined operation may be required when opening and closing. In order to facilitate the opening and closing of the body 12, it is preferable that the lid 12 can be opened and closed simply by lifting or placing it on the upper opening 11a.

Note that the storage container of this embodiment can also be used in the form of the main body container 11 without the lid 12. When the storage container is used in a clean environment, there is no possibility that foreign matter may enter the main body container 11 even if the lid 12 is omitted and the upper opening 11a is left open. When used in an environment with low cleanliness, it is desirable to cover the upper opening 11a with the lid 12.
When a plurality of storage containers are stacked up and down during transportation or use, a portion that fits or engages with the bottom 11b of the main body container 11 is provided on the upper surface of the lid 12 or the periphery of the upper opening 11a of the main body container 11. And it becomes difficult for the upper storage container to slip off, which is preferable.

  The notch 13 is for guiding the spout 4 to the spout receiving part 14. Therefore, it has a width that allows the spout 4 to be freely moved up and down within the notch 13 while maintaining the posture in which the tip end of the spout 4 of the inner bag 2 protrudes outside the main body container 11. In particular, when the inner bag 2 made of a flexible film is used, the width of the cutout portion 13 should be as narrow as possible in order to prevent a part of the inner bag 2 containing the contents from bulging out from the cutout portion 13. Is preferred. In order for the spout 4 to allow the cutout portion 13 to move up and down easily, the width of the cutout portion 13 should be wider than the outer diameter of the cylindrical portion of the spout 4 in order to ensure a gap with the spout 4. Is preferred. By inserting the spout 4, the gap between the side edges 13 a, 13 a of the notch 13 can be increased within the range of elastic deformation of the main body container 11, so that the width of the notch 13 is slightly smaller than the outer diameter of the spout 4 (for example, It can also be made narrow.

  The width of the notch 13 may be constant along the longitudinal direction of the notch 13 or may vary. For example, like the storage container 10A and the bag-in-box 1A in FIG. 2, a tapered portion 31a having a steep angle is provided on the upper opening 11a side so that the spout 4 can be easily received from above, and the spout is disposed below the tapered portion 31a. The parallel part 31b which has a width | variety comparable as the outer diameter of 4 can also be provided, and it can also be set as the structure which guides the spout 4 from both sides. Further, as in the storage container 10B and the bag-in-box 1B in FIG. 3, most of the cutout portion 13 is formed as a gently tapered portion 32a whose width gradually decreases downward from the upper opening portion 11a, and the spout restricting projection It is also possible to adopt a configuration in which a steep taper portion 32b is formed immediately above 15 and 15.

  The spout receiving part 14 is connected to the lower end of the notch part 13, and around the cross section of the cylindrical part of the spout 4 to receive the cylindrical part of the spout 4 of the inner bag 2 for bag-in-box. It has a circumferential edge 14a. For example, when the tube portion of the spout 4 is cylindrical, the spout receiving portion 14 can be formed by an arc-shaped cutout. In addition, when the remaining amount of the inner bag 2 decreases below the spout 4, the bag inbox can be tilted so that the spout 4 is directed downward or obliquely downward, and the discharge of the contents can be promoted. In order to take out more contents as much as possible, it is desirable to make the distance between the spout receiving part 14 and the bottom part 11b as short as possible.

  Further, in the case of the storage containers 10 </ b> A and 10 </ b> B shown in FIGS. 1 to 3, the main body container 11 protrudes in a facing direction at the boundary between each side edge 13 a of the notch 13 and the peripheral edge 14 a of the spout receiving part 14. It has a pair of spout stopping projections 15, 15 provided. The spout stopping projections 15, 15 engage with the top of the spout 4 when the spout 4 reaches the spout receiving portion 14, and the spout 4 received in the spout receiving portion 14 is notched. It is for stopping lifting to the part 13 side. For this purpose, it is desirable that the distance between the tips of the spout restricting projections 15, 15 be slightly smaller (for example, about several mm) than the outer diameter of the spout 4. When inserting the spout 4 into the spout receiving part 14 side, the spout stop projections 15 and 15 are elastically deformed by pushing the spout 4 downward and can be inserted easily. In order to stop the spout 4, the spout stop-protruding projection 15 may be provided only by projecting from one of the side edges 13 a of the notch 13. It is preferable to provide the spout stopping stop projections 15 as a pair on the side edges 13a on both sides because the spout 4 can be stopped more reliably.

  As a material for the main body container 11 and the lid body 12 constituting the storage containers 10A and 10B, a known molding material such as synthetic resin or metal can be used without particular limitation. Of these, synthetic resins are preferred because of their excellent moldability. Synthetic resins include polyolefin resins such as polyethylene (PE) and polypropylene (PP), polyester resins such as ethylene-vinyl acetate copolymer (EVA) and polyethylene terephthalate (PET), polyamide resins (PA) such as nylon, and polycarbonate. A thermoplastic resin such as a resin (PC) is suitable, but is not limited thereto. Examples of the method for forming the container include an injection molding method, a blow molding method, a vacuum molding method, and a pressure molding method, and are not particularly limited. The dimensions of the main body container 11 and the lid 12 are not particularly limited. For example, if the container is a small or medium container transported by one worker, one side of the storage container is 10 to 40 cm, the bottom 11b and the side parts 11c to 11f. The thickness can be about 1 to 10 mm.

  The formation of the cutout portion 13, the spout receiving portion 14, and the spout restricting projections 15 and 15 can be performed simultaneously with the molding of the main body container 11, or can be performed by post-processing by cutting or the like. Further, after molding the side surface portion 11c having the cutout portion 13 and the like, the remaining side surface portions 11d, 11e, 11f and the bottom portion 11b are formed by insert molding around the molded side surface portion 11c to form the main body container 11. You can also.

As described above, the storage container of this embodiment can be used as a bag-in-box by storing the inner bag 2. Here, the bag body 3 of the inner bag 2 may be a film-type flexible packaging bag formed by heat-sealing a film, or a flexible or semi-rigid container molded with a synthetic resin, but the storage container of the present invention is effective. A flexible packaging bag is preferable because it can be applied, easily reduced in volume and collected after use, and excellent in discardability. As a form of the flexible packaging bag, there are a gusset bag, a flat bag, a standing pouch and the like, and any form can be used without limitation.
The dimensions of the inner bag 2 are not particularly limited, but the inner volume is preferably 1 to 40 liters, particularly preferably about 2 to 20 liters.

  Although the raw material of the film which comprises the said flexible packaging bag is not specifically limited, Generally it is comprised with a synthetic resin film. As the synthetic resin film, when the inner bag is a flat bag, a single layer film or a plurality of laminated films are used. In the case of a single layer film, a film made of a thermoplastic resin such as polyethylene (PE) or polypropylene (PP), and in the case of a laminated film, these resins and nylon (Ny) or ethylene-vinyl alcohol copolymer (EVOH) A coextruded film of a gas barrier resin such as vinylidene chloride (PVDC) is used. When the inner bag is a gusset bag or a standing pouch, a laminated film is used, and a thermoplastic resin such as polyethylene (PE) or polypropylene (PP) is used as a heat sealant sealant layer, and polyethylene terephthalate (PET) or the like is used. A polyester resin, a polyamide resin such as nylon (Ny), or a laminate of a base material layer such as polypropylene (PP) is used. The base material layer is preferably a stretched film stretched in a uniaxial direction or a biaxial direction. For the base film, as a gas barrier layer for blocking gases such as oxygen and water vapor, for example, a resin layer such as ethylene-vinyl alcohol copolymer (EVOH) or vinylidene chloride (PVDC), a metal vapor deposition layer such as aluminum An inorganic compound vapor deposition layer such as silicon oxide or aluminum oxide can be laminated. Examples of the method for laminating the sealant layer and the base material layer include a dry laminating method, an extrusion laminating method, a co-extrusion method, and the like. An agent or the like is provided.

  Examples of resins used for semi-rigid molded type containers include polyolefin resins such as polyethylene (PE) and polypropylene (PP), ethylene-vinyl acetate copolymer (EVA), ethylene-vinyl alcohol copolymer (EVOH), and polyethylene. Polyester resins such as terephthalate (PET) are suitable, but are not limited thereto. Examples of the container forming method include blow molding, vacuum forming, and pressure forming, and are not particularly limited.

  As the spout 4, known ones can be used without any particular limitation. However, since the spout 4 can be fixed to the bag body 3 by heat sealing, a molded product made of a thermoplastic resin, or at least the bag body 3 is used. It is preferable to use a material in which a thermoplastic resin is used for the part to be heat-sealed. Examples of the thermoplastic resin include polyolefin resins such as polyethylene and polypropylene. In addition, when the bag body 3 is a semi-rigid molded type container, the spout 4 can be fixed by caulking. In this case, the material of the spout 4 may not be heat-sealed to the bag body 3. As shown in FIG. 1 (c), an annular groove 4 a that fits into the spout receiving part 14 is preferably provided around the spout 4. The groove 4a may be used to fix the spout 4 when the inner bag 2 is filled with the contents or when the contents are poured out while the inner bag 2 is stored in a transport container such as cardboard. it can.

  The tip of the spout 4 can be sealed by a closing means such as a cap 5 in general. The closing means is opened before the contents are used, and can be repeatedly opened and closed, or once opened, it cannot be resealed. In addition, a closing means having a falsification preventing function (pill fur proof property) can be used by leaving traces once opened. In order to facilitate the removal of the contents, when opening the closing means of the inner bag 2, a means for freely opening and closing the inner bag 2 such as a cock for a cap and a dedicated cock with a handle is attached to the tip of the spout 4. Is desirable.

  In addition, it is preferable to provide the handle 6 on the bag body 3 because the operation of storing the inner bag 2 in the storage container becomes easy. In order to provide the handle 6 on the bag body 3, for example, a method in which a heat-sealed portion of the film constituting the bag body 3 is protruded in an ear shape and a hole is formed to allow the hand to pass through the protrusion is used as the handle 6. Or a method of fixing a separately formed molded article to the bag body 3. When the bag body 3 is a semi-rigid molding type container, the handle 6 can be molded simultaneously with the bag body 3.

  In order to store the inner bag 2 in the storage containers 10A and 10B having the spout restricting projections 15 and 15 to form the bag-in-box 1A and 1B, the bag body 3 is stored in the main body container 11 and then the lid 12 It may be covered. In order to fix the spout 4 to the spout receiving part 14, the cutout 13 is formed from the upper opening 11a while maintaining the posture in which the spout 4 is turned sideways and the tip of the spout 4 is projected outside the main body container 11. Further, a downward pushing force is applied at the spout restricting protrusions 15 and 15 to engage the spout restricting protrusions 15 and 15 with the upper part of the cylindrical portion of the spout 4. When the groove 4 a is provided in the cylindrical portion of the spout 4, it is preferable to fit the spout receiving portion 14 and the spout restricting projections 15, 15 into the groove 4 a.

  As described above, according to the storage containers 10 </ b> A and 10 </ b> B of the embodiments of the present invention, the inner bag 2 can be stored in the main body container 11 while the tip end portion of the spout 4 is exposed to the outside of the main body container 11. Since it is possible, the spout 4 can be easily set in the spout receiving part 14 without losing sight of the position of the spout 4. Further, after the spout 4 is set in the spout receiving part 14, the upward movement of the spout 4 is restrained by the spout restraining projections 15 and 15, so that the spout 4 can be fixed securely. . In the obtained bag-in-boxes 1A and 1B, the tip end of the spout 4 is exposed to the outside of the main body container 11 through the spout receiving part 14, so that the lid 12 remains on the opening 11a of the main body container 11. The content item can be taken out from the inner bag 2, and the work of taking out the content item from the inner bag 2 is easy. Furthermore, since the level of the liquid level of the content item stored in the inner bag 2 through the notch 13 can be visually checked, the remaining amount of the content item can be easily confirmed.

4 and 5 are views showing a third embodiment of the inner bag storage container for a bag-in-box according to the present invention, and FIG. 4 (a) is an exploded perspective view in which a part of the lid is cut away. 4 (b) is a perspective view, FIG. 4 (c) is a sectional view taken along the line CC of FIG. 4 (b), and FIG. 5 is a front view.
A storage container 10 </ b> C shown in these drawings includes a main body container 11 and a lid 12, and a bag-in-box 1 </ b> C can be configured by storing an inner bag 2 having a bag main body 3 and a spout 4 inside. . In FIG. 5, the position in which the inner bag is stored is indicated by a two-dot chain line, and the tip end portion of the spout is omitted.

In the case of the storage container 10 </ b> C shown in FIGS. 4 and 5, as a means for fixing the spout 4 to the spout receiving part 14, instead of providing the spout stop restraining projection 15 on the main body container 11, A spout stop piece 16 is provided. When the lid is closed, the lower end portion 16a of the spout stop piece 16 abuts on the upper portion of the spout 4 so that the spout 4 received by the spout receiving portion 14 is moved to the notch 13 side. It is intended to stop lifting. For this purpose, the spout restricting piece 16 has a sufficient length and extends downward from the main body 12 a of the lid 12. Further, the lower end portion 16 a of the spout stopping piece 16 has a shape (for example, an arc shape) along the periphery of the cross section of the spout 4.
Further, the upper end portion 16b of the spout restricting piece 16 is connected to the lower surface of the main body portion 12a that is inside the peripheral wall portion 12b of the lid body 12, and the spout restricting piece 16 is connected to the inside of the main body container 11 when the lid is closed.

Further, the width of the spout stop piece 16 is larger than the width of the cutout portion 13, and both side edges 16 c and 16 c of the spout stop piece 16 are outside the side edges 13 a and 13 a of the cutout portion 13 when the lid is closed. The left and right sides of the portion 13 are in contact with the inner surface of the side surface portion 11c of the main body container 11.

  In the storage container 10C of this embodiment, the material and manufacturing method of the main body container 11 and the lid body 12 constituting the storage container 10C can be the same as those of the above-described storage container 10C. The spout stop piece 16 can be formed at the same time as the lid 12 is formed, or after the spout stop piece 16 is formed in advance, the main body is formed by insert molding around the formed spout stop piece 16. It is also possible to form the lid body 12 by molding the portion 12a and the peripheral wall portion 12b. The dimensions of the main body container 11 and the lid 12 are not particularly limited. For example, if the container is a small or medium container that is carried by one worker, one side of the storage container can be 10 to 40 cm. The thickness of the spout stop piece 16 only needs to have sufficient mechanical strength to stop the spout 4 when the lid is closed, and is, for example, about 1 to 10 mm.

  In order to store the inner bag 2 in the storage container 10 </ b> C having the spout stop piece 16 to form the bag-in-box 1 </ b> C, the bag body 3 may be stored in the main body container 11 and then covered with the lid 12. In order to fix the spout 4 to the spout receiving part 14, the cutout 13 is formed from the upper opening 11a while maintaining the posture in which the spout 4 is turned sideways and the tip of the spout 4 is projected outside the main body container 11. The lid body 12 is closed and the lower end portion 16a of the spout stopping piece 16 is brought into contact with the upper portion of the spout 4 so that the spout receiving portion 14 and the spout receiving portion 14 are brought into contact with each other. The cylindrical portion of the spout 4 is sandwiched between the outlet stop piece 16. As shown in FIG.4 (c), when the groove | channel 4a is provided in the cylinder part of the spout 4, it is preferable to make the spout receiving part 14 fit in this groove | channel 4a.

  As described above, according to the storage container 10 </ b> C of this embodiment, the inner bag 2 can be stored in the main body container 11 while the tip end portion of the spout 4 is exposed to the outside of the main body container 11. The spout 4 can be easily set in the spout receiving part 14 without losing sight of the position 4. Moreover, since the upward movement of the spout 4 is stopped by the spout stop piece 16 after setting the spout 4 in the spout receiving part 14, the spout 4 can be fixed reliably. In the obtained bag-in-box 1 </ b> C, the tip end portion of the spout 4 is exposed to the outside of the main body container 11 through the spout receiving portion 14, so that the inner bag remains on the opening 11 a of the main body container 11. The contents can be taken out of the inner bag 2, and the work of taking out the contents from the inner bag 2 is easy. In addition, when the spout restricting piece 16 is made transparent, the level of the liquid level of the content item stored in the inner bag 2 can be visually observed through the transparent spout restricting piece 16, so that the remaining content item remains. The amount can be easily confirmed.

  Furthermore, the spout stop piece 16 can be inserted into the inside of the main body container 11 when the lid is closed, and both side edges 16c, 16c of the spout stop piece 16 are connected to the main body container at both side edges 13a, 13a of the notch portion 13. 11, the inner bag 2 for bag-in-box 2 can be pressed from the outside. Therefore, when the inner bag 2 is a film-type inner bag, the inner bag 2 is deformed and one of the inner bags 2 is deformed. It is possible to reliably prevent the portion from protruding outward from the notch portion 13.

In the present invention, it is possible to provide both the above-described spout blocking stop projections 15 and 15 and the spout blocking stop piece 16 in a single storage container, and use both together. In this case, the spout 4 can be more securely fixed to the spout receiving part 14.
In the storage container of the present invention, the main body container 11 and / or the lid body 12 may be provided with a transparent part in whole or in part for the purpose of seeing inside. Further, a mesh-like or honeycomb-like hole or window may be opened.
In order to facilitate carrying of the storage container, the storage container may be provided with a protrusion, a through hole, a recess, or the like serving as a handle.

Next, the handling method of the inner bag for bag in boxes using the inner bag storage container for bag in box of this invention is demonstrated.
As described above, paper dust generated from corrugated cardboard causes foreign matter at work sites where it is necessary to manufacture in an environment that dislikes paper dust (sometimes referred to simply as “clean environment” in this specification). There were restrictions on the use of bag-in-boxes. In contrast, the bag-in-boxes 1A, 1B, and 1C of the present invention can be used without problems in the clean environment because the storage containers 10A, 10B, and 10C are made of a material that does not generate paper dust. . By the way, if the storage container is exposed to an environment that does not like paper dust for a long time, the storage container may become dirty, and cleaning may be required before being carried into the clean environment again.

In order to solve the above-described problems, the following steps (a) to (d) are performed in the method for handling an inner bag for a bag-in-box according to the present invention.
(A) An inner bag is stored in a transport container made mainly of paperboard and transported.
(A) Remove the inner bag from the transport container and transfer it to the storage container before the clean environment. Thereby, the bag in box formed by storing the inner bag in the storage container is configured.
(C) Carry the bag-in-box into a clean environment.
(D) In a clean environment, use the bag-in-box with the inner bag stored in the storage container.

  Here, the space in which the bag-in-box inner bag stored in the transport container is transported generally includes a space (non-clean environment) having a low cleanliness such as outdoors. In addition, the space where the inner bag is transferred from the transport container to the storage container is a carry-in space that is generally attached to the clean environment in order to take appropriate measures before carrying various deliveries into the clean environment. It has a cleanness intermediate between clean and non-clean environments. In this carrying-in space, a cleaning device, an air shower, a suction device that sucks dust, dust, or the like can be provided as necessary.

  In this way, by removing the inner bag from the transport container and storing it in the storage container of the present invention before carrying it in a clean environment, the work environment caused by paper dust generated from the transport container or dust adhering to the transport container is reduced. Contamination can be prevented. In the case of the storage container of the present invention, since the spout is in a posture protruding sideways from the side surface of the storage container, the contents can be taken out from the inner bag while the lid is placed on the opening of the main body container. For this reason, after carrying the bag-in-box into a clean environment, it is not necessary to change the positional relationship between the top surface and the side surface of the bag-in-box and can be quickly installed at the destination. In addition, since it is not necessary to firmly connect the storage container and the lid body, the storage container itself can have a simple structure, and complicated work is required when the inner bag is stored in the storage container and the lid body is closed. Will not occur and the time and effort can be reduced.

  The storage container is taken out of the clean environment only when the inner bag is transferred from the transport container. However, since the storage container is installed in the clean environment for most of the time, the possibility of contamination by external foreign matters can be extremely reduced. For this reason, even when the inner bag is transferred to the storage container and carried into the work site, no time-consuming washing such as washing with water is necessary, and if necessary, it can be completed in a short time, such as blowing clean air. By simply performing such a process, it is possible to obtain a clean state that can be carried into the work site.

  Since the inner bag can be handled as it is stored in a storage container in a clean environment, it is easy to handle when carrying it in, and the content of the spout is maintained regardless of the remaining amount of content. Also easy to take out. In addition, it is easy to replace the inner bag when taking out the empty inner bag from the storage container and replacing it with the inner bag containing the new content after use of the content is completed, and store it when the inner bag is replaced Cleaning the container can be omitted.

  As the inner bag 2, the same one as the inner bag 2 in the above-mentioned bag-in-box can be used, and in particular, a film-type flexible packaging bag formed by heat-sealing a film is preferable. In order to facilitate transfer from the transport container to the storage container, it is preferable to provide a handle 6 on the inner bag 2. In order to provide the handle 6 on the inner bag 2, for example, a method in which the heat-sealed portion of the film constituting the bag body 3 of the inner bag 2 protrudes in an ear shape to form the handle 6 or a separately formed molded product is used. The method etc. which fix to the bag main body 3 are mentioned.

  The transport container 20A is used to prevent external impact (particularly impact during transportation or storage) and to maintain a certain shape. In the handling method of the present invention, since the transport container is not carried in a clean environment, the material of the transport container 20A is not particularly limited, and any paperboard used for the outer bag-in-box exterior container is used. Is possible. Specific examples include paper boards such as white paperboard, yellow balls, chip balls, and colored balls, and paperboards such as various cardboards. Of these, corrugated cardboard is preferred because it is inexpensive and excellent in impact resistance.

Moreover, it is preferable that a transport container has the easy tearing means which consists of the perforation 21 and / or the cut tape 22 in the side surface 23, as shown in FIG.6, FIG.7, FIG.8.
Here, the transport container 20 </ b> A shown in FIG. 6 is provided with perforations 21, 21 in the vertical direction along two sides on the left and right sides of one side surface 23, and easily tears the paperboard along the perforations 21, 21. It is something that can be done. In this case, the inner bag 2 can be taken out very smoothly by tilting the side surface 23 and opening the opening of the transport container 20A.
Here, each of the perforations 21 and 21 preferably has an upper end reaching the upper opening of the transport container 20A and a lower end extending to the bottom of the transport container 20A.

The transport container 20B shown in FIG. 7 is provided with cut tapes 22 and 22 in the vertical direction along two left and right sides of one side 23, and is cut by pulling the cut tapes 22 and 22 attached to the back surface of the paperboard. The paperboard can be easily cleaved together with the tapes 22 and 22. In this case, the inner bag 2 can be taken out very smoothly by tilting the side face 23 and opening the opening of the transport container 20B.
The transport container 20C shown in FIG. 8 is provided with a cut tape 22 in a circumferential shape that circulates a side surface in the lateral direction, and an end of the cut tape 22 affixed to the back surface of the paperboard is exposed from a cut 24 provided on the side surface of the transport container 20C. When the inner bag 2 is taken out from the transport container 20C, the upper 25a and the lower part 25b of the transport container 20C can be separated by pulling the cut tape 22 and tearing the paperboard. In this case, the inner bag 2 can be taken out very smoothly by removing the upper portion 25a of the transport container 20C.

  The cut tape 22 preferably has a high tensile strength. For example, a pressure-sensitive adhesive tape in which a stretched film such as stretched polypropylene or stretched polyethylene is used as a support and an adhesive layer is provided on one side of the support is suitable. The cut 24 for exposing the end of the cut tape 22 to the outer surface side of the transport container may be formed in a horizontal H shape so that it can be pulled from the both ends of the cut tape 22 in the left-right direction as shown in FIG. Although it is preferable, it is not particularly limited to this. For example, the cut tape 22 can be formed in a U shape so that it can be pulled in one direction.

  In order to confirm the effect of the present invention, a bag-in-box was produced according to the following procedure, and a subdivision test was performed.
