Description

Bag package and manufacturing method of bag package

Technical field

TECHNICAL FIELD [0001] The present invention relates to a bag packaging body having a self-supporting property for a fluid such as a liquid, a viscous body, a powder or a granule, and a method for producing the bag packaging. The present invention relates to a bag packaging body of a fluid such as a liquid, a viscous body, a powder, or a granule having a self-supporting property, and a manufacturing method of the bag packaging body.

Background art

[0002] Stand-bouches are widely adopted as self-supporting bag packages. In particular, a stand bouch that wraps a fluid has a stenosis outlet. When the stenosis outlet cap is configured, the stenosis outlet does not close, so there is no inconvenience when the fluid flows out. However, if the stenosis outlet is made up of spouts, the cost is considerably increased.

Therefore, it is necessary to provide a stenosis outlet without using a sputt in order to keep costs low.

When a stenosis outlet is provided without using a spout on a stand bouch, in most cases, a stenosis outlet is provided at the corner of the upper part of the bag in order to make it easy to discharge all the fluid. The device is designed not to close it. Furthermore, as the fluid flows out, the front part and the rear part of the bag approach each other, and when the entire amount of fluid comes out, the front part and the rear part of the bag come into close contact and lose their independence. (See Patent Document 1, Patent Document 2, and Patent Document 3).

When a stenosis outlet is provided in the center of the top of the bag without using a sputt on the stand bouch, a male hook and a female hook are placed at both corners of the bag to make it easy to discharge all the fluid. A stop is provided and connected so that the entire amount of the fluid is directed toward the stenosis outlet, but a device has been devised to prevent the stenosis outlet from closing (Patent Document 4, Patent (Ref. 5). In addition, in a refill bag using a stand pouch, as a contrivance for the entire amount of fluid to be directed to the stenosis outlet, it is devised to fold along a 45-degree line from the opening at one corner of the top of the bag toward the other side.

Problems to be solved by the invention

[0003] All of the bag packagings of the above-mentioned patent documents are self-supporting when they are unopened. When the animal flows out, the front part and the rear part of the bag approach each other and gradually become self-supporting. There is a problem that the stenosis exit is closed.

[0004] The purpose of the present invention is not only to be self-supporting when not opened, but also when the stenosis outlet is opened at the center of the upper part of the front portion of the bag and the bag is inclined to allow the fluid to flow out. Even after the entire amount of fluid that does not close and the front part and the rear part approach each other is discharged, the front part and the rear part of the bag remain separated and remain self-supporting. It is providing the manufacturing method of a bag packaging body and a bag packaging body which have these.

Means for solving the problem

[0005] The bag packaging body of the present invention opens the upper end opening of the stand bouch and fills with a fluid, flattenes the upper end portion of the bag including the upper end opening in a cross shape, and forms the flat portions on both sides on the rear surface of the bag. Folded to the flat part on the side, the flat part on the front side of the bag and the three flat parts are made flat on the side of the bag side, and a top heat seal is applied to the upper ends of all the flat parts, and the top heat seal The superposition of the three flat portions described above is maintained, and the outlet is configured to cut out a part of the upper end corner of the flat portion on the front side of the bag to flow out the fluid.

Furthermore, the above configuration is such that the upper end opening is equal to the bag width, the upper end opening of the stand bouch is flattened in a cross shape, the upper end portion of the bag is formed into a cross-shaped flat portion, and the flat portions on both sides are folded on the flat portion on the back side of the bag Thus, it can be configured as described above.

In the above configuration, the size of the top opening when the bag is flat is about half of the bag width, and the center of the top opening matches the center of the bag width, and the top opening of the stand bouch is elongated in the front-rear direction. The upper end of the bag is formed into a cruciform flat portion, and the flat portions on both sides are folded over to the flat portion on the back side of the bag. It is preferable that heat sealing is performed along an oblique line connecting the half folded end of the bottom gusset of the end and one end of the same upper end opening.

[0006] The above bag packaging manufacturing method includes a pair of bag sandwiching means that sandwich the left and right front and back surfaces of the upper portion of the stand bouch, which is required from the upper end, with the upper end opening equal to the bag width, and the like. The upper end of the bag is opened by reducing the distance of the holding means and sucking the front and rear surfaces of the upper part of the bag with a pair of vacuum pads to separate the pair of vacuum pads, and the fluid is discharged from the upper end of the bag. Then, the suction of the pair of vacuum pads is released and the force is flattened so that the distance between the pair of bag holding means is further reduced to form a cross-shaped constriction opening when the upper end opening of the stand bouch is viewed from above. The three flat portions except the front side of the force bag are aligned on the rear side of the bag, and the upper end opening is clamped from the left and right directions with a pair of heat sealers and heat sealed.

[0007] In addition, another bag package of the present invention is a stand-bouch in which the size of the upper end opening when the bag is flat is about half the bag width, and the center of the upper end opening matches the center of the bag width. Open the top opening, fill it with fluid, flatten the top opening in the front-rear direction, make the top end of the bag a cruciform flat part, flatten the top opening on both sides, and close the top opening Folded on both sides of the flat portion on the back side of the bag, the flat portion on the front side of the bag and the three flat portions are flat on the side of the bag, and the top ends of all flat portions are top heat sealed, and The top heat seal is used to maintain the overlapping of the three flat portions, and the outlet is configured to cut out the upper end corner portion on the front side of the bag, thereby allowing the fluid to flow out.

In this bag package, it is preferable that the stand bouch is heat-sealed along a line connecting the lower end of the bag inner end on the same side and one end of the upper end opening when the bag is flat.

[0008] The manufacturing method of the above bag package body is from the upper end of the stand bouch in which the size of the upper end opening when the bag is flat is about half of the bag width, and the center of the upper end opening matches the center of the bag width. The left and right front and rear surfaces of the upper part of the bag that are separated from each other are clamped by a pair of bag clamping means, the distance between the pair of bag clamping means is reduced, and the front and rear surfaces of the upper part of the bag are sucked by a pair of vacuum pads. The pair of vacuum pads are separated from each other to open the upper end of the bag, fill the fluid from the opening at the upper end of the bag, and then release the suction of the pair of vacuum pads to force the pair of bag sandwiching means. The upper end opening of the stand bouch is flattened so that it is long in the front and back direction and closed and sealed, and the three flats except for the front side of the bag are aligned on the back side of the bag and the upper end is closed. The opening is sandwiched between a pair of heat sealers from the left and right directions and heat sealed.

The invention's effect

It is self-supporting and can be used as a container for fluids even after opening. For example, it can be used as it is for pouring soy sauce.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described with reference to the drawings.

[Form of Stand Bouch Used for Bag Packaging of the Present Invention]

Fig. 1 (a) to (g) shows various types of stand bouches used in the bag package of the present invention. As shown in Fig. 1 (a), a stand bouch is made of a double-sided heat-sealing packaging material. The bottom part of the boat shape when it is unfolded in three dimensions with the bottom part 3 sandwiched between the front part 1 and the rear part 2 that make up the bag with the inner side heat-sealing packaging material half-folded The bottom heat seal 4 is applied and the side seals 5 and 5 are applied.

The standbouch Pla shown in (a) is a normal bag, and the width of the bag space is the same from the lower end to the upper end opening.

The stand pouches P2a to P7a, except for the above stand pouches, P2a to P7a are designed so that the size W2 of the top opening when the bag is flat is about half the bag width W1, and the center of the top opening matches the center of the bag width. V is common in that it has a configuration.

The stand bouch P2a shown in (b) is a best mode bag used in the bag package of the present invention, and the intersection point i between the inner end of the bag and the half-folded end of the bottom gusset, and one end of the same upper end opening on one side. Heat seals 5b and 5b are applied to the side edges along the diagonal line k connecting j.

The stand bouch P3a shown in (c) has a trapezoidal space that gradually decreases in width as the middle part in the vertical direction in the bag goes upward, and this trapezoidal space has a bag-inside width dimension of the bag. Heat seals 5c and 5c are applied so as to communicate with a small-diameter space having an upper end opening that is approximately half the width W1.

The stand pouch P4a shown in (d) has a trapezoidal space that gradually decreases in width as the upper part in the bag goes upward, and the upper end of this trapezoidal space is about the width of the bag W1. Heat seals 5d and 5d are applied so that the upper end opening is half.

The stand bouch P5a shown in (e) and the stand bouch P6a shown in (f) are obtained by slightly changing the shape of the heat seals 5d and 5d of the stand bouch P4a shown in (d).

The stand pouch P7a shown in (g) is obtained by applying two point seals 5g and 5g to the upper end opening of a normal stand bouch so that the distance between the point seals is about half of the bag width W1.

[0011] The stand bouches P2a to P2g in Figs. L (b) to (g) are all self-supporting when the bottom part 3 expands into a boat shape if a fluid is filled and a top seal is applied to the top opening. Have When these stand-up pouches P2a to P2b are filled with fluid from the top opening, the top opening naturally expands in the front-rear direction due to the pressure of the fluid. In addition, when the fluid flows out by opening the top corner, the bag flattens until the front part 1 and the rear part 2 come into close contact with each other, and loses its independence.

[Embodiment 1 of bag packaging body]

FIG. 2 (d) shows the bag package Plb according to the first embodiment. This bag package Plb is a bag package that has a three-dimensional shape fixed by using a stand-bouch Pla shown in FIG.

[0013] As shown in Fig. 2 (a), this bag package Plb opens the upper end opening of the stand bouch Pla and fills with fluid, and as shown in Fig. 2 (b), the upper end of the stand bouch Pla Opening in a cross shape Flatten the upper end of the bag into a cruciform flat, and fold the flats 7 and 8 on both sides to the flat 9 on the back side of the bag as shown in Fig. 2 (c). Thus, the top heat seal 11 is applied to the upper ends of all the flat portions 7, 8, 9, 10 with the flat portion 10 on the front side of the bag and the three flat portions 7, 8, 9 as a plane on the bag side surface, In addition, the top heat seal 11 maintains the superposition of the three flat portions 7, 8, 9 and flows the fluid out by opening a part of the upper corner of the flat portion 10 on the front side of the bag. It is characterized by an exit.

[0014] Then, it is not essential to provide the top heat seal 11 with a notch 12 for opening an opening along the opposite side of the corner of the flat part 10 so as to be opposite to the triangle!

[0015] The bag package of the present invention has a form in which the two flat portions 7, 8 on the side of the bag are overlapped with the flat portion 9 on the bag rear surface side, so that the front surface portion 1 and the rear surface portion 2 In the range from the lower half to the middle, it spreads in a substantially cylindrical shape by the pressure of the fluid, and in the upper part of the front part 1 and the rear part 2, the horizontal cross-sectional shape of each central part is a loop-shaped fold.

This loop shape has a smaller radius of curvature until the top heat seal 11, so when the flat portion 10 on the front side of the bag is cut open into a triangle, the opening remains largely open in a loop shape, The flow of fluid and the flow of external air from the opening smoothly and simultaneously do not cause negative pressure in the bag, so the front and rear surfaces approach each other and avoid deflation. Permanent solid shape is guaranteed, and the solid shape is maintained and self-supporting even after the entire amount of fluid is discharged.

[0016] Accordingly, the bag package Plb has a shape in which the stenosis outlet is looped, particularly when the stenosis outlet is not closed when the fluid is flown out by opening it at the corner of the flat part 10. When the fluid flows out, the air enters the bag well, so it is possible to avoid the front part 1 and the rear part 2 from approaching and deflating, and the three-dimensional shape is maintained even after the entire amount of fluid is drained. Has independence.

For this reason, in the process where the entire amount of fluid is not used up, the opening can be closed with a holding tool such as a clothespin and used as it is as a storage container, or it can be used as it is as a soy sauce pouring if it is made into a small bag.

[0017] The bag package shown in Fig. 2 has a cross-shaped narrow opening 6 with a cruciform shape in which the bag left-right dimension is approximately twice as large as the bag front-rear direction dimension. Fold stenosis opening 6 FIG. 2 shows a package formed by applying a top heat seal 11 formed by wrapping, and the top heat seal 11 is a force applied along the upper ends of the flat portions 7, 8, 10. The body may be applied so that the corner forces of the flat portions 7 and 8 also connect points 10 mm to 20 mm below the corner of the flat portion 10. In this case, the top heat seal 11 Since the overhanging portion on the upper side becomes larger than the above, it is preferable to cut and arrange the form.

[0018] Further, the bag package of the present invention folds the cross-shaped constriction opening 6 by taking the cross-sectional constriction opening 6 from the bag upper side and taking the same size in the left-right direction of the bag as the front-rear direction of the bag. The top heat seal 11 may be formed, and the top heat seal 11 may be a package body provided along the upper ends of the flat portions 7, 8, 10. Since the bag package of this form can take a large width dimension of the flat portion 10, the take-out amount is large, and it is preferable to apply it to the packaging of fluids. In this case, since the overhanging portion is smaller than the top heat seal 11, the overhanging portion may or may not be excised.

[0019] The bag package of the above configuration is a proof that the top heat seal 11 is applied to the overlap of the flat portions 7, 8, and 9 so that the flat portions 7, 8, and 9 are welded. The front part 1 and the rear part 2 constituting a bag made of a packaging material having double-sided heat sealability are used.

[0020] However, the present invention is not limited to this. Even with the front part 1 and the rear part 2 constituting the bag made of the packaging material having the inner surface heat sealability, the top heat seal 11 is applied to the overlap of the flat parts 7, 8, 9 to obtain the flat parts 7, 7. 8 and 9 can be closed.

[0021] Specifically, it is necessary to use a stand pouch with punch holes provided at both corners where no force is exerted on the side seal at the upper end of the bag rear surface. Then, when the cross-shaped narrowed opening 6 is taken from the upper side of the bag, for example, the size in the lateral direction of the bag is twice as large as the size in the longitudinal direction of the bag, the two flat portions 7 on the side of the bag 7, 8 is overlapped with the flat portion 9 on the back side of the bag, and both corners of the flat portions 7 and 8 are projected rearward from the flat portion 9 on the back side of the bag so that the corners of the flat portions 7 and 8 are directly connected to each other. When the top heat seal 11 is applied over the punch holes and welded through the inner surface of the front surface portion of the bag, the inner surface of the rear surface portion of the bag, and the punch holes, the flat portions 7, 8, and 9 can be closed. .

[0022] The two flat portions 7, 8 on the side of the bag are overlapped with the flat portion 9 on the back side of the bag, so that the side seals on both sides of the portion reaching the lower end of the bag 5, any horizontal Since the cross section is closer to the rear side, the heat sealer is pressed against the side seals 5 on both sides from the front outer side and overlapped on the rear side, or the side seals 5 on both sides On the other hand, when the front outer force is pressed against the rear surface by pressing the pressure bar and high-temperature heated air is blown onto the overlapping surface to apply heat sealing, the center force of the bag is exerted on both sides of the part reaching the lower end of the bag The side seal 5 is in the form of a bag with no overhang.

It is only necessary to overlap the rear surface of the side seal 5 at least at the lower end. When this bag shape is adopted, the side seal 5 does not get in the way when stored in a cardboard box, so that it can be aligned more in the same space.

[0023] The bag packaging body of the present invention may use the front surface portion 1 and the rear surface portion 2 constituting the bag, either of the packaging material having double-sided heat sealing properties or the packaging material having internal heat sealing properties. As shown in Table 1 below, a wide range of packaging materials can be used.

[0024] [Table 1]

The bag package of the present invention is made of soy sauce, sauce, oil, drinking water, detergent, shampoo, most other liquids, kneaded wasabi, kneaded pepper, mustard, caulking, most other viscous agents, and seasonings. It is suitable for the packaging of wheat flour 'detergent' fine granular foods and beverages and most other powders or granules. [Embodiment of manufacturing method of bag package]

Next, as shown in FIGS. 2 (a) to (d), a manufacturing method for manufacturing the bag package Plb using the standbouch Pla will be described.

First, as shown in FIG. 3 (a), the left and right front and rear surfaces of the upper part of the bag, which is also separated from the upper end force of the stand bouch Pla, are clamped by a pair of bag clamping means 21, and the separation distance between the pair of bag clamping means 21 is increased. The upper end of the bag is opened by sucking the front and rear surfaces of the upper portion of the bag with a pair of vacuum pads 22 and separating the pair of vacuum pads 22, and a filling chute or auger 23 is inserted into the opening at the upper end of the bag. Fill with a fixed amount of fluid.

The stand voucher Pla has a front part 1 and a rear part 2 made of a double-sided heat-sealing packaging material.

Next, as shown in FIG. 3 (b), after releasing the suction of the pair of vacuum pads 22, the distance between the pair of bag sandwiching means 21 is further reduced, whereby the upper end of the stand bouch P1. The opening is flattened so that it becomes a cross-shaped constriction opening 6 as seen from the upward force. That is, four flat parts 7, 8, 9, and 10 are formed. At this time, it is preferable to perform point heat sealing so that the flat portions 7, 8, 9, and 10 are not opened and are kept flat. In particular, when the pair of bag sandwiching means 21 is viewed from above, the crossing angle of the extension line of the pair of bag sandwiching means 21 is set to, for example, 160 degrees to 120 so that the distal end of the bag sandwiching means 21 protrudes to the front side of the bag from the base end. As a result, the two flat portions 7 and 8 on the side of the bag are bent according to the crossing angle of the pair of bag holding means 21 while also seeing the upper force. This is because the next process is smoothly performed by simple means. Note that the flat portions 9 and 10 can be flattened by increasing the thickness of the bag clamping means 21.

Next, as shown in FIG. 3 (c), the closing means 24 opened in a V shape from the front side of the bag is advanced to the upper side of the pair of bag sandwiching means 21 to force-close the bag. The two flat portions 7, 8 on the side surface are overlapped with the flat portion 9 on the back side of the bag, and the flat portion 10 on the front side of the bag and the three flat portions 7, 8, 9 are flat on the bag side surface side. .

Next, as shown in FIG. 3 (d), when the top heat seal 11 is applied by pressing the upper ends of all the flat portions 7, 8, 9, 10 with the heat seal 25, the stand bouch Since P1 has a front surface portion 1 and a rear surface portion 2 made of a packaging material having double-sided heat sealability, the top heat seal 11 can maintain the overlapping of the three flat portions 7, 8, and 9. This completes the manufacture of the bag package Plb that can hold the three-dimensional shape.

[Embodiment 2 of bag packaging body]

FIG. 4 (d) shows a bag package P2b according to the second embodiment.

The stand bouch P2a shown in Fig. 4 (a) is the same as the stand bouch having the configuration shown in Fig. 1 (b). This bag package P2b is a bag package that has a three-dimensional shape fixed by using a stand bouch P2a to enhance its self-supporting property.

[0031] As shown in Fig. 4 (a), this bag package P2b opens the upper end opening of the stand bouch P2a and fills it with fluid, and as shown in Fig. 4 (b), the upper end of the stand bouch P2a. The opening is flattened in the front-rear direction and the upper end of the bag is formed into a cruciform flat, and the flats 37, 38 on both sides are folded into flats 39 on the back side of the bag as shown in Fig. 4 (c). As shown in FIG. 4 (d), the flat portion 40 on the front surface side of the bag and the three flat portions 37, 38, 39 are flat on the side surface side of the bag, and all flat ridges 37, 38, 39, 40 A top heat liner 41 is applied to the upper end, and the top heat seal 41 maintains the superposition of the three flat portions 37, 38, 39, and the upper corner portion of the flat portion 40 on the front side of the bag is formed. It is characterized by an outlet that allows fluid to flow out by opening it. A notch 42 is provided in the top heat seal 41 but is not required.

[0032] When the stand pouch P2a is used, the three-dimensional shape of the bag package of the present invention is most easily formed. In other words, when the stand bouch P2a was filled with water and observed for deformation, it was flattened naturally by the water pressure so that the upper end opening became longer in the front-rear direction.Therefore, the two flat portions 37, 38 on the side of the bag were The folding process of overlapping the flat part 39 on the back side of the bag is good and stable, and the flat part 40 on the front side of the bag and the three flat parts 37, 38, 39 are all flat on the side of the bag. A top heat seal 41 is applied to the upper end of each flat portion, and the top heat seal 41 can easily perform a sealing process for maintaining the overlapping of the three flat portions 37, 38, 39.

In addition, when this stand bouch P2a is used, the flat portions 37, 38 on both sides are heat-sealed and no internal space is formed, so the fluid does not turn in the direction of the flat portions 37, 38. Immediately finished in a tight three-dimensional shape.

[0033] In the stand pouch P2a shown in Fig. 4 (a), the bottom 33 expands into a boat shape when filled with fluid. When the fluid flows out, the bag returns to a flat state and the front part 31 and the rear part 32 come into close contact with each other and loses its independence. In the case of the bag package P2b shown, the three-dimensional shape is maintained and the independence is maintained without returning to the flat state even if the fluid flows out.

[0034] Other components that are the same as or equivalent to those in the first embodiment have substantially the same functions and effects as those in the first embodiment, and thus redundant description is omitted.

[0035] The manufacturing process from the stand bouch P2a shown in FIG. 4 (a) to the stand bouch P2b shown in FIG. 4 (d) is shown in FIG. 2 (&) → (1 ₎ ) → ( ₍ :: → (( The description is omitted because it is almost the same as the manufacturing process shown in 1).

[0036] [Another embodiment of the bag package]

The first embodiment is a bag package Plb using the stand-bouch Pla shown in FIG. 1 (a), and the second embodiment is a bag-packaging using the stand-bouch P2a shown in FIG. 1 (b). Although the bag package P2b has been described, the present invention is not limited to these two embodiments. Even if the stand bouches P3a to P7a shown in any one of FIGS. L (c) to (g) are used, FIG. A bag package manufactured in substantially the same manner as the folding shown in (a) to (d) is also included in the present invention (the invention of claim 3).

[0037] Fig. 1 (c) to (g)! The stand top pouches manufactured using stand pouches P3a to P7a as shown in Fig. 1 (c) are also filled with water. Since it flattens naturally so as to be long, the folding process for overlapping the two flat portions 37, 38 on the side of the bag with the flat portion 39 on the back side of the bag is good and stable. This is the same as the bag package P2b manufactured using the standbouch P2a shown in FIG.

As described above, the embodiments of the bag package of the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to the above-described embodiments, and various designs without departing from the gist of the present invention are not limited. It includes changes. For example, this includes the case where the flat portions 10 and 40 on the front side of the bag are provided with spouts. Further, the spout may be either a type that is exposed when the corners of the flat portions 10 and 40 are cut out, or a type that extends from the beginning to the outside of the bag internal force.
