Description

  TECHNICAL FIELD The present invention relates to an assembly container for a liquid packaging body, and in particular, a packaging body made of a liquid material in a liquid packaging bag in which a liquid pouring nozzle having a check function is provided in a bag body formed using a soft laminated film. It is characterized by an assembly-type container for storing and suspending and holding a liquid packaging body filled with an object, particularly a sheet-like structure used for assembling the container.

Liquid and jelly-like food and drink, dressings and seasonings that may contain granular materials, alcoholic beverages, oils and other packaging containers that can be poured out multiple times, Patent Document 1 and Patent Document 2, A packaging bag comprising a bag body made of a soft laminated film and a liquid dispensing nozzle formed so as to protrude from the side or top of the bag is disclosed. According to this packaging bag, the to-be-packaged product is poured out by the deformation of the soft packaging bag according to the amount of dispensing, and the outside air from the dispensing nozzle accompanying the dispensing is discharged into the packaging bag. Since there is no uptake (backflow), it is possible to effectively eliminate the possibility of oxidation, flavor reduction, and fouling of the packaged items in the bag. Moreover, such a dispensing nozzle with a non-return function tilts the packaging bag and dispenses the article to be packaged, and then returns to the original standing posture, so that the dispensing is quickly stopped and the nozzle tip is poured. Since the outlet is sealed and the outside air can be reliably prevented from entering the bag through the nozzle, the packaged item can be used up to the end.

  Since the packaging bags described in Patent Document 1 and Patent Document 2 are made of a soft film and are not self-supporting or formable by themselves, they transport a liquid packaging body filled and packaged with an article to be packaged. In the case of storage, display, use, etc., it is necessary to store it in a paper or resin box or the like with fixing or fixing at a plurality of locations. Moreover, when this liquid packaging is stored in a box or the like, the non-return function of the pouring nozzle is exhibited, and in order to prevent dripping, the pouring nozzle is accurately stored in the target position, It is necessary to firmly fix the inside of the box or the like by hot melt or the like. However, this storing operation requires many steps, and in order to mechanize it, there are problems in accuracy and cost, and the actual situation is that it has not been put into practical use.

  Therefore, the inventors have realized the reduction in cost and the practical application of the liquid packaging body by having the customer himself / herself perform the operation of storing the liquid packaging body in a box or the like. We examined as much as possible. As a result, the present inventors can suspend and hold the liquid package and can effectively exert the check function of the pouring nozzle, and the customer can use it quickly without using an adhesive or the like. We have developed a container that is easy to assemble and that can be used for recycling, and that allows easy mounting and dismounting of liquid packaging from the assembly container.

That is, the present invention is an assembly type container for a liquid packaging body for storing and holding a liquid packaging body having a liquid pouring nozzle having a check function, and a locking pin for hanging the liquid packaging body on the upper side And a generally circular body sheet made of a substantially rectangular flexible thermoplastic resin that surrounds the body of the liquid packaging body, and a substantially circular shape that supports the bottom of the liquid packaging body. The body sheet is formed of a bottom sheet insertion slit formed along the bottom edge , a notch for a back window hole provided in a center portion in the width direction, and both end portions in the width direction. of, comprising a engaging Tomeana near the lower portion of the primary, as well as organic and locking piece to the other near the lower portion, a pin hole for hanging by sandwiching the upper portion of the liquid material packaging body from the upper edge folding the flap is being projected, the bottom sheet, the outer circumferential edge in contact with the barrel seat It was projected pieces Insert number, and with the body portion exhibits a bottomed cylindrical in the assembled state, the Rukoto such a superposition upper portion adjoin each other is folded from-out top notch for the back window opening An assembly container for a liquid packaging product.

In the liquid material wrapping material assembled container of the present invention, before kidou unit sheet to have a cutout for the front window opening at both end portions in the width direction, and the width direction of the body portion sheet music It is made into a substantially cylindrical shape, and the bottom sheet insertion slit is inserted into the bottom sheet insertion piece to form the bottom, and the locking hole is engaged with the locking piece, A cylindrical body is formed, and the upper part of the body is folded from the notch for the back window hole to form an overlapping upper part, and the liquid packaging body is formed in the pin hole in the overlapping upper part. It is preferable that the upper edge of the liquid packaging body is suspended through a locking pin and fitted into the pin hole of the folded flap so that the folded flap is folded to sandwich the upper edge of the liquid packaging body. It becomes a solution.

The assembly container for a liquid packaging body of the present invention is mainly formed by injection molding and punching a resin sheet to form a trunk sheet and a bottom sheet, and by combining them together, without using an adhesive, It can be easily assembled. For this reason, it is possible for a customer who uses the liquid packaging body to assemble it into a cylindrical container, and to store (suspending) the liquid packaging body in this container. This eliminates the need for work and can reduce the cost of the product.
In the assembly container of the present invention, since the liquid packaging body can be suspended and held in the assembly container by the locking pins, the liquid packaging body can be easily replaced.
Moreover, since the assembly container of this invention is comprised from a resin-made sheet-like member, it can be repeatedly used by replacing the liquid packaging body to accommodate. Therefore, what is discarded after pouring out the packaged item is only the empty bag of the liquid package, which can contribute to volume reduction of garbage.

Embodiments of the present invention will be described below with reference to the drawings.
First, a liquid packaging body is demonstrated. FIG. 1 is a perspective view showing an example of a liquid packaging body 10, a bag body 2 formed by heat-sealing a soft plastic laminated film, and a pour-out projecting at one upper end of the bag body 2. A packaging bag made of the nozzle 1 is filled with an article to be packaged made of, for example, a liquid or a viscous material. That is, the bag body 2 and the pouring nozzle 1 are made of a laminated film having at least a base film layer and a sealant layer, and can be formed integrally or, for example, can be an unstretched polyethylene layer or a polypropylene layer. The layer can be manufactured by fusing by heat sealing, high frequency sealing, impulse sealing or the like at a required side portion of the laminated film. Below, the case where the bag main body 2 and the extraction nozzle 1 are fusion-bonded is demonstrated. In addition, the melt | fusion part of the bag main body 2 and the extraction | pouring nozzle 1 is shown with the oblique line in the figure.

  At the same time as filling the packaging body into the bag body 2 or prior to filling the packaging body, the dispensing nozzle 1 is, for example, a fusion part between the sealant layers on the side of the bag body 2, A sealant layer on the outer surface of the base end portion of the nozzle 1 is bonded to the inner surface of the bag body 2, preferably by heat sealing, so that it becomes a part of the packaging bag. To protrude.

A packaging bag becomes the liquid packaging body 10 which becomes a full form by filling and packaging a to-be-packaged object there, Preferably under aeration. And in pouring out the package packed and packaged in the liquid packaging 10, the pouring nozzle 1, as shown in FIG. 1, from the V-shaped bent portion 3 of the upper fused portion 5, The tip portion of the nozzle 1 is removed by tearing, for example, with fingers, and then the liquid packaging 10 is tilted, preferably with a box or the like for storing and holding it. Thereby, the front-end | tip spout of the nozzle 1 of the liquid packaging body 10 will fully open | release to the front and back side by the water head pressure of the package thing in a bag, and the extraction | pouring as needed will be performed. .
When the article to be packaged is dispensed in this way, the soft bag body 2 contracts or collapses by an amount corresponding to the dispensed volume without sucking outside air as the article to be packaged is dispensed. Will be transformed.

After the required amount of the package is poured out by tilting the liquid package 10, the liquid package 10 is returned to its original standing position to stop the pouring, and based on the stoppage of the pouring, The inner surface of the nozzle wetted with the package is adhered to each other under the thin film of the package, and simultaneously with the stop, the width of the film on the front and back of the dispensing nozzle 1, in other words, the entire vertical direction. In this way, the tip spout of the nozzle 1 is sealed, and the entry of outside air into the liquid packaging 10 is reliably prevented.
Therefore, in the liquid packaging body 10 including the dispensing nozzle 1, the packaged material in the bag is sufficiently protected from contact with the outside air during and after the dispensing as well as before the packaging material is dispensed. As a result, oxidation, fouling and the like of the packaged items in the bag are effectively prevented.

By the way, such close contact of the films on the front and back of the pouring nozzle 1 is caused by the upright return of the liquid packaging body 10. In addition to the discharge nozzle 1 being released from the action of the water head pressure and returning to the original shape at the time of manufacture, the packaged item in the dispenser nozzle 1 is wetted by the packaged item when it returns to the interior 2 The inner surfaces of the front and back films are in close contact with each other, and this is exposed to a reduced-pressure atmosphere so that the inner surfaces of the films are adsorbed to each other, thereby producing a check function that prevents the intrusion of outside air. The close contact between the films of the pouring nozzle 1 is based on the elastic restoring force inherent to the bag body 2 that is shrunk or crushed and deformed with the pouring of the package from the liquid packaging 10. This is more certain when the inside is made to have a reduced pressure tendency.
Thus, in this case, the tip outlet of the liquid packaging body 10 can be automatically and tightly sealed together with the rising and returning of the liquid packaging body 10 without any special operation for the dispensing nozzle 1. An excellent check function can be exhibited.

  In the liquid packaging body 10 having such a check nozzle 1 with a non-return function, the bag body 2 is made of a soft plastic film, and is not self-supporting or fixed in itself. It is preferable to store the liquid packaging 10 in a holding container. Therefore, in the present invention, a container that can accommodate (suspend and hold) such a liquid packaging 10 is made possible and can be assembled, and a reusable assembly container has been studied.

  FIG. 2 is a schematic view showing an example of the body sheet 21 and the bottom sheet 22 constituting the assembly container 20 of the present invention. Each of the body sheet 21 and the bottom sheet 22 is formed by injection molding or stamping a hard thermosetting resin or the like, and is formed of two different sheets as shown in FIG. In the unfolded state, the torso sheet 21 is substantially the same on the left and right sides with respect to the center in the width direction. 23, and the locking pins 43 and 44 are provided corresponding to the pin holes 30c and 30d of the left trunk sheet 21L.

  Next, a method for assembling the assembly container 20 used to store and suspend the liquid packaging 10 using the upper body sheet 21 and the bottom sheet 22 will be described. As shown in FIG. 3, the back window hole notch 40 portion provided at the center of the body sheet 21 (the middle between the left and right body sheets 21L and 21R) is bent, and the side edge of the bottom sheet 22 is formed on this body part. Inserted into the lower part of the sheet 21 and bent along the side edges thereof, the insertion pieces 24 and 25 provided on both sides of the bottom sheet 22 are inserted into the insertion slits 26 provided in the lower part of the trunk sheet 21, 27 respectively.

  Next, the middle part of the body sheet 21 is rounded in the width direction, and a locking hole 28 and a turn-back locking piece 29 provided in the vicinity of the lower part of both ends in the width direction, that is, the left body sheet 21L. A folding container 29 provided on the right trunk section sheet 21R is hooked and locked in the locking hole 28 provided in the container, thereby forming a cylindrical container.

  Next, as shown in FIG. 4, the upper part of the container body bent into a bottomed cylindrical shape is folded from substantially the center in the width direction of the trunk sheet 21, and the left and right trunk sheets 21 </ b> L, 21 </ b> R are folded. And the pin hole 30c and the pin hole 30d are fitted to the locking pins 43 and 44 disposed so as to face each other, and the left body sheet is formed. The folding flap 23 projecting from the upper end of 21L is bent to the overlapping upper portion 42 side, and the pin holes 30a, 30b provided in the folding flap 23 and the locking pins 43, 44 are fitted to overlap each other. The assembly container 20 is formed by firmly fixing the upper portion 42 and the locking pins 43 and 44. Actually, the liquid packaging body 10 is fitted into the assembly container 20 by using the locking pins 43 and 44 through the suspension holes 7 and 8 provided in the upper lateral seal portion thereof. Will be suspended and held.

  As described above, in the present invention, as shown in FIG. 3, the notch 40 for the back window hole is provided in the center portion in the width direction of the trunk sheet 21, and the width direction both ends of the trunk sheet 21 are provided. It is preferable to provide front window hole notches 41a and 41b. This is effective in bending the body sheet 21 in the width direction and making it easy to fold when assembling the container 20 as described above by the notches 40, 41a, 41b. This is because the liquid packaging body 10 can be easily accommodated in the container 20 because it can be opened. Moreover, the remaining amount of the packaged object in the liquid packaging body 10 can be visually confirmed from the window holes by the notches 40, 41a, 41b, and further, by pressurizing the trunk portion of the container 20 These notches 40, 41a, 41b are effective in guiding the pressurization of the liquid packaging 10 inside and aiming for the discharge (discharge) of the contents, so that the smooth discharge is possible. To secure.

  Next, a method of suspending and holding the liquid packaging 10 in the container 20 assembled as described above will be exemplified. First, the folding flap 23 is removed from the locking pins 43 and 44, and then the upper portion of the container 20 is opened by removing the right body sheet 21R from which the folding flap 23 is not provided from the overlapping upper portion 42 from the locking pins 43 and 44. To do. Subsequently, the liquid packaging body 10 is accommodated in the container 20 from the upper part of the opened container 20, and the suspension pins 43 and 44 are previously formed on the upper lateral seal portion of the liquid packaging body 10. After hooking the suspension holes 7 and 8, the pin holes 30 c and 30 d are further fitted to form the overlapping upper part 42. Further, the liquid flap 10 is fixed and suspended in the container 20 by bending the folded flap 23 toward the overlapping upper portion 42 and fitting the locking pins 43 and 44 into the pin holes 30a and 30b. It will be.

  Then, while the liquid packaging body 10 is suspended and held in the assembly container 20 as described above, the assembly container 20 is tilted, or the body portion of the container 20 is pressed by hand. An article to be packaged can be poured out from the nozzle 1. This is because the head pressure of the article to be packaged is applied to the nozzle 1 of the liquid packaging 10 by the tilting or pressing of the container 20, and the nozzle 1 is sufficiently opened on the front and back sides.

The body sheet 21 and the bottom sheet 22 are excellent in strength, are self-supporting when the assembled container 20 is formed, are flexible, and are a material such as a thermosetting resin that can be flexibly deformed. the Ru used. For example, it is preferable to use a resin sheet of any one of polypropylene, polyethylene, polyethylene terephthalate, nylon, and polystyrene. This is because, by using a soft and flexible material, the bag body 2 of the liquid packaging body 10 accommodated in the container 20 is pressed from the outside of the container 20 while being adjusted by hand, and the tip of the dispensing nozzle 1 This is because it is effective in dispensing the packaged items.

  Moreover, it is preferable that the thickness of these sheets 21 and 22 is 0.3-3.0 mm. This is because when the thickness is less than 0.3 mm, sufficient strength for suspending and holding the liquid packaging 10 cannot be obtained, and when it exceeds 3.0 mm, the sheet cannot be flexibly deformed. This is because the upper portion of the container 20 cannot be greatly widened and opened, making it difficult to store the liquid packaging 10.

  Further, the sheets 21 and 22 may be transparent, translucent, or opaque, and in the case of being transparent or translucent, the remaining amount of the package can be grasped from the outside of the container 20.

Moreover, in this invention, you may affix a hollow and a non-slip | skid sheet | seat in the substantially center position of each width direction of the left-right trunk | drum sheet | seats 21L and 21R, ie, the position grasped with a hand when the container 20 is lifted. When this dent is provided, it becomes a clue when holding the container 20 by hand, the liquid packaging body 10 can be directly pushed by hand, and the package can be discharged from the dispensing nozzle 1, and further the package There is an effect that the remaining amount can be visually confirmed.
Further, the non-slip sheet is made of a rubber system such as a silicon sheet, a urethane rubber sheet, or a butyl rubber sheet, and prevents the container 20 from sliding off from the hand and serves as a mark for a position held by the hand.

  The pin holes 30a, 30b, 30c, 30d formed in the upper part of the folded flap 23 and the right trunk sheet 21R are circular with a diameter of about 4 to 6 mm. It is preferable to form a cross-shaped cut to facilitate fitting to 43 and 44.

  The present invention suspends and holds a soft packaging bag having a pouring nozzle having a check function suitable for a packaged item requiring dispensing multiple times, such as food and drink, as well as food and drink. In addition to being useful as a container, it can be suitably used as a container for suspending and holding a soft packaging bag in which a dispensing nozzle and a discharge port are provided so as to protrude from the bag body.
