Description

  The present invention relates to a refilling standing pouch filled with a plurality of contents.

  Standing pouches are used as refill containers that contain liquid substances such as liquid detergents. Of these standing pouches, when the contents are used up at once, the spout is usually opened by cutting the film forming the standing pouch, but the contents are used in several times. In order to be able to store the standing pouch with the contents remaining, a resin spout member generally called a spout and a cap screwed to the spout member are attached (Patent Document 1).

JP 2005-206163 A

  However, in order to form the spout in the standing pouch, providing a spout and a cap that are separate from the film that forms the standing pouch increases the manufacturing cost of the standing pouch, and the amount of resin for the separate pouch increases. Because it is required, the environmental load is also increased.

  On the other hand, the present invention is a refilling standing pouch filled with the contents of a plurality of times. The standing pouch itself can be opened without using the film forming the standing pouch and a separate member. The purpose of the present invention is to enable the storage of a standing pouch that is closed by the shape of the container and whose contents remain.

  The present inventor, for a standing pouch having a spout opened at the upper part, when the film is folded so as to wind the opened spout, a mechanism such as a hook that holds the folded state is used as a film constituting the standing pouch. It has been found that the above-mentioned object can be achieved by forming according to the shape of the material.

That is, the present invention is a standing pouch in which a pair of opposing films are bonded with side seals to form a body portion, and has an opening serving as a spout at the top,
Provided is a standing pouch having a folded state holding mechanism that holds a body portion folded from an upper end twice or more so as to involve a spout.

According to the standing pouch of the present invention, since the spout once opened can be closed by folding the trunk portion of the standing pouch, the standing pouch can be stored with the contents remaining.
Furthermore, according to the present invention, since the spout once opened is held in a closed state, a spout or a cap is unnecessary, and the spout can be closed in the shape of the film material itself. Therefore, the amount of resin required for manufacturing the standing pouch can be reduced and the environmental load can be suppressed. In addition, the manufacturing method is simplified, and the manufacturing cost of the standing pouch can be reduced.

Hereinafter, the present invention will be specifically described with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.
FIG. 1 is a plan view of an unopened state of a standing pouch 1A according to an embodiment of the present invention. This standing pouch 1A accommodates multiple times of refilling liquids such as dishwashing detergents, hair washing agents, whole body washing agents, etc., and multiple times of refilling powders of clothes detergents, detergents for automatic dishwashers, bleaching agents, etc. It is used as a refill container, and a pair of opposing films 2 are bonded by side seals 3 and upper seals 4 at both left and right end portions to form a body portion 5. In addition, a film forming a gusset is bonded to the bottom portion 6 so as to be able to stand on its own. A notch 7 is formed at the upper end of the standing pouch 1A, and the spout 8 is opened by tearing the film as shown by a broken line. In the plan view, a portion filled with dots is a seal region where the opposing film is bonded.

  This standing pouch 1A is different from a gusset bag in that there is no gusset on the side surface. In a gusset bag with gussets on the side, since there are two side seals at the left and right end portions, it is difficult to hold the folded state of the body portion by engaging or fitting the side seals.

  In the trunk portion of the standing pouch 1A, two broken lines 10a and 10b are formed so as to cross the standing pouch 1A. Here, the polygonal lines 10a and 10b are formed by forming a thin film or a strip having a convex surface on the surface and a concave surface on the back side. As will be described later, the broken lines 10a and 10b enable the trunk portion 5 to be folded twice so as to entrain the spout 8.

  In addition, with respect to the formation position of the bottom side folding line 10b, when the height from the bottom side folding line 10b and the bottom side of the standing pouch 1A is set to H1 and H0, respectively, it can be folded even when the amount of residual liquid is large, In view of maintaining the folded state, it is preferable to set H1 / H0 to about 1/2.

  The side seal 3 is provided with a side seal fixing mechanism for engaging the side seals 3 that overlap each other by folding, as a folded state holding mechanism that holds the body 5 folded along the folding lines 10a and 10b. It has been. More specifically, cuts 11a, 11b, and 11c are formed in the side seal 3. The formation positions of the cuts 11 a, 11 b, and 11 c in the side seal 3 are portions where the side seals 3 are overlapped by folding the trunk portion 5. Further, as the shapes of the cuts 11a, 11b, and 11c, when the body part 5 is folded at the folding lines 10a and 10b and the cuts 11a, 11b, and 11c are engaged with each other, the folded state of the body part 5 can be maintained. In this embodiment, notches 11a and 11b extending horizontally from the edge of the side seal 3 are formed in the side seal above the upper bent line 10a and the side seal between the two bent lines 10a and 10b. A cut 11c is formed in the side seal on the bottom side of the lower broken line 10b. The cut 11c is obliquely cut from the edge of the side seal 3 to the trunk side.

This standing pouch 1A is used as follows.
First, the spout 8 is opened by cutting the film 2 from the notch 7 (FIG. 1B), and a part of the contents is discharged into the refill container. Thereafter, the trunk portion of the standing pouch 1A is folded along the upper fold line 10a (FIG. 1C), and further, the trunk portion is folded along the lower fold line 10b so as to wind the spout 8. By this folding, the spout 8 is closed and the spout 8 is surrounded by the film 2 of the body portion 5 and is blocked from the outside. Further, the side seals 3 overlap in a triple manner, and the aforementioned notches 11a, 11b, and 11c also overlap. Therefore, the cuts 11a, 11b, and 11c are formed so that the cut pieces 11cc that can be caused by the oblique cuts 11c located on the outer surface of the back side pass through the other cuts 11a and 11b to the outer surface of the front side. Engage (FIG. 1D). By engaging the triple notches, it is possible to reliably hold the folded state of the body portion 5 that closes the spout 8 and shields the spout 8 from the outside, so that the standing pouch 1A can be stably stored with the contents remaining. It becomes possible.

  As described above, since the standing pouch 1A is stored in a state in which the body portion 5 is folded, product information such as a product name is preferably provided in the lower region 5b of the body portion that does not overlap the folded portion. .

  In the present invention, the side seal fixing mechanism for engaging the side seal can take various forms. For example, in the standing pouch 1B of FIG. 2A, the width of the upper portion of the trunk portion that is first folded at the fold line 10a in the standing pouch 1A of FIG. Even when the body 5 is overlapped in a threefold manner, the side seal 3 is formed with a portion that overlaps only twice, and the same cuts as the above-mentioned cuts 11b and 11c of the standing pouch 1A are formed in that portion. Are provided, and the upper notch is omitted from the upper broken line 10a.

  Also in the usage method of the standing pouch 1B, first, the spout 8 is formed by cutting the film from the notch 7 (FIG. 2B), and a part of the contents is discharged into the refill container, and then the standing pouch 1B The trunk is folded along the upper fold line 10a (FIG. 2C), and the trunk is folded along the lower fold line 10b so that the spout 8 is wound. By this folding, the spout 8 is closed and surrounded by the folded film of the body 5. In addition, in the region where the side seals 3 are overlapped by folding, a portion that overlaps only twice is formed between the front film and the back film forming the outer surface, and cuts 11b and 11c are formed in this portion. Therefore, the cuts 11b and 11c are engaged so that the cut piece 11cc that can be caused by the cut 11c on the back side passes through the cut 11b on the front side and comes out to the outer surface on the front side (FIG. 2D). Since this engagement is to apply double overlapping cuts, the hooking operation is simpler than that in which triple overlapping cuts are applied, but also this closes the spout 8 and closes the spout. It is possible to maintain the folded state of the body 5 that shields 8 from the outside. Therefore, it is possible to store the standing pouch 1B with the contents remaining.

  The standing pouch 1C in FIG. 3A is a side seal fixing mechanism for engaging the side seals 3 that overlap with each other by folding the body 5 and maintaining the folded state. Cuts 11b and 11c are formed in the seal 3a between the two broken lines 10a and 10b and below the lower bent line 10b, respectively. In the side seal 3b on the opposite side to the spout 8, these cuts are formed. In addition to 11b and 11c, a cut 11a is also formed above the upper broken line 10a.

  As for the shape of the cut, the cut 11b between the broken lines 10a and 10b is a butterfly shape, and a pair of upper and lower cut pieces 11bb corresponding to the wings can be caused. Further, the notch 11a above the upper bent line 10a and the notch 11c at the bottom side of the lower bent line 10b are a pair of parallel straight notches that engage with the butterfly-shaped notch 11b, and are side seals. It extends from the edge of 3 in the horizontal direction.

  Even in the standing pouch 1C, after the spout 8 is opened, the body 5 is folded twice along the fold line 10a and the fold line 10b, and the folded state is maintained by engaging the cuts 11a, 11b, and 11c formed in the side seal 3. However, in this case, as shown in FIG. 3B, in the side seal 3a on the spout 8 side, the double notches 11b and 11c are engaged, and in the side seal 3b on the side opposite to the spout 8 is tripled. The overlapping cuts 11a, 11b, and 11c are engaged.

  Further, in this engagement, the pair of upper and lower butterfly-shaped cut pieces 11bb of the cut 11b are pressed by the other cuts 11c (or 11a and 11c), so that a more stable hooked state can be obtained.

  The standing pouch 1D shown in FIG. 4A has a butterfly-shaped notch 11b as a side seal fixing mechanism and a notch 11c formed of a pair of parallel lines in the side seal 3a on the spout 8 side, and is provided on the side opposite to the spout 8. It is provided only on the side seal 3b. When the film forming the standing pouch is easy to fold, only one of the side seals 3a and 3b on the left and right sides may be provided with a cut serving as a side seal fixing mechanism.

  Further, in this standing pouch 1D, after the body part 5 is folded twice by the broken line 10a and the broken line 10b, a part of the spout 8 protrudes from the film of the body part 5 folded, and the spout 8 is a film of the body part 5. In this case as well, the spout 8 is closed by folding the body 5, so that the standing pouch 1D can be stored with the contents remaining.

  Similarly to the above-described standing pouch 1D, the standing pouch 1E shown in FIG. 5A is provided with notches 11a, 11b, and 11c serving as side seal fixing mechanisms only on the side seal 3b opposite to the spout 8.

  Further, in this standing pouch 1E, the cut 11b between the broken lines 10a and 10b has an arrow shape, and the cut 11a above the upper bent line 10a and the cut 11c on the bottom side of the lower bent line 10b are A horizontal cut line that engages with the arrow-shaped cut 11 b is formed within the width of the side seal 3.

  In this standing pouch 1E, after opening the spout 8, the body 5 is folded twice by a broken line 10a and a broken line 10b, and as shown in FIG. 5B, the tip of the arrow-shaped cut piece 11bb is formed by a horizontal cut line 11a, By inserting into 11c, the notches 11a, 11b, and 11c are engaged. Thus, by forming the notch 11b in an arrow shape, it becomes easy for a general user to understand how to fix the body portion 5 of the standing pouch 1E in the folded state.

  The standing pouch 1F of FIG. 6A is provided with a mountain-shaped cut 11c on each of the side seals 3 on the left and right sides as a side seal fixing mechanism. As shown in FIG. 6B, the ridge-shaped cut 11c is formed at a position where the lower end portion 12 of the fold mountain when the barrel 5 is folded twice by the fold line 10a and the fold line 10b after the spout 8 is opened can be just pressed. Has been.

  When the film forming the standing pouch is easy to fold and the body 5 is firmly folded by the folding lines 10a and 10b, the folded state of the body 5 can be maintained by such simple engagement. .

  The standing pouch 1G shown in FIG. 7A is provided with uneven processing 13b and 13c that are fitted to each other as a side seal fixing mechanism, instead of the above-described notches 11b and 11c. The irregularities 13b and 13c are formed integrally with the standing pouch by forming a film that forms the standing pouch. For example, as shown in FIG.

  The formation positions of the irregularities 13b and 13c are the part located on the outer surface on the front side and the part located on the outer surface on the back side of the side seal 3 that overlaps when the body part 5 is folded. In addition, in the upper end portion of the side seal 3 and the portion that will be sandwiched between the concave and convex portions 13b and 13c by folding the trunk portion 5, the fitting of the concave and convex portions 13b and 13c is not hindered. Stupid holes 14 are provided.

  In this standing pouch 1G, after opening the spout 8, as shown in FIG. 7B, the body 5 is folded twice by the broken line 10a and the broken line 10b, and the uneven processing 13b, 13c formed on the side seals 3a, 3b is fitted. By combining, the folded state of the body portion is maintained. Also with this standing pouch 1G, since the spout 8 that has once been opened is held in a closed state, a spout or cap is unnecessary, and environmental load can be suppressed and manufacturing costs can be reduced.

  The standing pouch 1H of FIG. 8A is provided with a rib 15 extending in the standing direction of the standing pouch at the lower portion of the body portion 5 of the standing pouch 1A of FIG. 1A. Such a rib 15 can stabilize the standing state as shown in FIG. 8B when the trunk portion 5 of the standing pouch 1H where the contents remain is folded and stored along the fold lines 10a and 10b.

The standing pouch 1I shown in FIG. 9A has a rib 15 similar to that described above provided in the lower portion of the body 5 of the standing pouch 1D shown in FIG. 4A.
In addition to the folding lines 10a and 10b for folding the body 5, the folding line 10c is further formed on the standing pouch 1I on the bottom side. As shown in FIG. 9B, when the body 5 is folded at the fold lines 10a and 10b and the cuts 11b and 11c are engaged with each other, the center of gravity is biased toward the body 5 side where the film is folded, and as shown by the broken line in FIG. However, as shown in FIG. 9C, the standing pouch 1I with the body portion 5 folded can be bent into a square shape and the standing state can be stabilized by the bent line 10c on the bottom side. Here, the fold line 10c on the bottom side is a fold line that is weaker than the fold lines 10a and 10b for folding the trunk, and the film of the trunk 5 is not easily folded in half, but bent into a square shape. It is preferable to make it a broken line.
Stabilization of the standing state of the standing pouch 1I with the trunk portion 5 folded in this way is particularly effective when the standing state is difficult to stabilize because the standing pouch is tall.

  In the present invention, as the folded holding state mechanism for holding the folded state of the body part, a releasable adhesive region may be provided in the body part in addition to the side seal fixing mechanism for engaging or fitting the side seals.

  The broken line of the body part 5 may be simply printed. Also, the broken line can be omitted depending on the film material forming the standing pouch. Usually, it is assumed that the number of folding corresponds to two or more. If the number of folds is one, the opened spout 8 cannot be surrounded by the film of the trunk portion 5, and there is a risk of dripping. From the viewpoint of simplifying the folding operation, twice is preferable to three times.

  The standing pouch of the present invention can be manufactured by a conventional method except that a folding holding state mechanism is provided. As a film for forming the standing pouch, in addition to a resin film such as polyethylene, polypropylene, PET, nylon, etc., the resin is made of aluminum. -A film in which alumina or silica is vapor-deposited or a film in which thin-film aluminum is laminated can be used.

  Further, in the present invention, the above-described configuration of the standing pouch can be combined as appropriate, and various forms can be taken with respect to the cut shape and the like.

  INDUSTRIAL APPLICABILITY The present invention is useful as a refill container for a plurality of refills of powders such as dishwashing detergents, laundry detergents, softeners, whole body detergents and the like, and detergents for clothes, automatic dishwashers, bleaching agents, etc. is there.
