DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container formed of a flexible sheet, and more particularly to a bag-like container which is filled with a liquid or a viscous substance and is formed to be free standing.

[0002]

2. Description of the Related Art In recent years, as shown in FIG. 8 (a), a bag formed by heat-sealing an edge of a flexible sheet such as a synthetic resin film and a laminate sheet such as aluminum foil. A container 17 in which a separate mouth 12 molded from synthetic resin is attached to the upper end edge of the container body 11 by heat sealing is often used as a container in which a liquid or a viscous body such as a beverage is filled. Have been.

[0003]

This container 17 is shown in FIG.
By heat sealing the edges of the four sheet pieces as shown in (b), a container body 11 having front and rear face pieces 11a and 11b and side gussets 15a and 15b is formed.
11 is provided with gussets 15a, 15b and a bottom portion 14 and is formed to be self-supporting, but the gussets 15a, 15
The folding width of 15b was so small that it did not hinder the sealing of the container body 11 and the mouth 2.

For this reason, when the gussets 15a and 15b are expanded to form the container body 11 three-dimensionally, the thickness of the container body 11 is reduced, and the container body 11 tends to fall back and forth during self-support. In particular, when the beverage is filled, careless container body
When the 11 fell, the beverage inside spilled, so it needed to be stable on its own.

[0005] A sealing portion 13 in which each sheet piece is heat-sealed protrudes outward at a corner of the container body 11. Since each of the sheet pieces is formed of a synthetic resin film and a laminated sheet of aluminum foil or the like as described above, the sheet body has a certain degree of rigidity, and the cutting edge obtained by laminating and cutting the sheet bodies Becomes the seal portion 13 in a sharp and hard state.

Accordingly, if the tip of the seal portion 13 contacts the palm of the hand when the container body 11 is gripped, not only is it difficult to grip, but if the user slides his hand carelessly at the cut edge, the hand may be hurt. . In particular, the mouth portion 12 as described above is attached, and a beverage or the like is poured out from the mouth portion 12, or the mouth portion 12 is directly
In the case of a container that sucks a beverage from the
There is a problem as described above because the user often uses the device while directly holding the device.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and provides a container which is less likely to damage a hand due to a cut edge of a sheet when gripped and has good self-sustainability. As an issue.

[0008]

Means for solving the problems according to the present invention include a container body 1 made of a flexible sheet and a mouth attached to the container body 1. A gusset 5a, 5b which is folded inward on both sides of the container body 1 is formed in the container composed of the portion 2 and the two gussets 5a, 5b together with the sheet piece 1a on one side of the container body 1 and the mouth portion 2. The two gussets 5a and 5b are attached to one face side X in a sealed manner,
mm.

According to the present invention, both gussets 5a and 5b are
Attached to the mouth 2 together with the sheet piece 1a on one side of
In addition, since the distal ends of both gussets 5a and 5b have an interval of 2 to 10 mm, a predetermined width between the distal ends of both gussets 5a and 5b is provided between the mouth 2 and the mounting portion of the container body 1. Since the sheet piece 1a on one side of the container body 1 and the mouth portion 2 can be sealed, a non-sealable portion that cannot be sealed at the attachment portion between the mouth portion 2 and the container body 1 hardly occurs, and the mouth portion 2 and the container body 1 Can be surely adhered and sealed.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, the configuration of the container of the present invention will be described. 1 shown in FIG. 1 to FIG. 4 is formed by forming a single sheet into a cylindrical shape and further folding the four sides into corners so that an object to be stored such as a beverage can be sealed inside. Container body.

As shown in FIG. 4, the container body 1 has front and rear side pieces 1a, 1b and gussets 5a, 5b on both sides, each having a corner 4a.
Is provided via Of the four corners 4, the three corners 4 are formed by bending the sheet body, and the inner surface side of the sheet body is heat-sealed with a width of about 3 to 8 mm to protrude as a support piece 6 to the outer surface side. ing.

At the other corner 4, the overlapping portion 9 of the sheet is heat-sealed on its inner surfaces as shown in FIG. 5A, and the leading end is bent as shown in FIG. It is formed as a support piece 6 like the other three corners 4.

In order to form such a container body 1 from a sheet, for example, as shown in FIG. 6A, the inner surfaces of both ends of the sheet are combined to form a superposed section 9, and the superposed section 9 of the sheet is formed.
After bending the end portions of the gussets 5b and the gussets 5a and 5b to form the corner portions 4, as shown in FIG.
Is heat-sealed at the tip. Then, the four corners 4 can be formed as the support pieces 6 as described above.

FIG. 6 shows one sheet of the overlapping portion 9.
As shown in (a), a plurality of pairs of sealing holes 7 are formed in the vertical direction, and the heat sealing surface of the other sheet body is exposed. By sealing, the heat seal hole 7 is fixed so as to maintain the bent state.

As shown in FIG. 6A, a notch 8 is formed on one gusset 5a at the upper end near the corner 4 of the gusset 5a, so that the front and rear face pieces 1a, 1a, 1b are exposed to each other, and when the upper edge of the container body 1 is heat-sealed, the container body 1 is closed at the upper edge.
The front and rear side pieces 1a and 1b can be fixed at the position of the notch 8. Similarly, on the other gusset 5b side, the front and rear side pieces 1a and 1b of the container body 1 are fixed at the position of the notch 8, but in the overlapping portion 9, the notch 8 is provided on the rear side piece 1b side of the container body 1.
Is formed, the notch 8 can face the sheet body of the front piece 1a of the gusset 5b and be heat-sealed when the tip of the overlapping portion 9 is bent toward the gusset 5b as described above.

The bottom portion 3 of the container body 1 is sealed so that the front and rear pieces 1a, 1b and the lower portions of the gussets 5a, 5b are tapered toward the lower center as shown in FIG. It is formed. When the gussets 5a and 5b are expanded, the bottom surface 3 becomes a substantially square bottom surface, and the container body 1 becomes self-supporting.

As a material of the sheet body of the container body 1, a gas barrier film such as a polyester film such as polyethylene terephthalate, a polyamide film or the like and an aluminum foil, an ethylene vinyl alcohol copolymer film, or a film on which an inorganic substance is vapor-deposited. Any material can be used, such as a laminated film in which a layer of heat-sealable resin such as polyethylene or polypropylene is formed on the inner surface of the laminated film, or any other material such as a synthetic resin film. What is necessary is just to be able to store drinks and other objects to be stored.

Reference numeral 2 denotes a mouth portion 2 which is simultaneously clamped when the upper end edge portion of the container body 1 is heat-sealed in a flat shape and sealed at the same time. 2b
And a lid 2c which is detachably mounted, for example, by being screwed into the spout 2b. The mounting part 2a and the spout part 2b of the mouth part 2 are integrally molded from a synthetic resin having thermal adhesion to the inner surface of the container body 1 such as polypropylene or polyethylene.

The mouth 2 and the container body 1 are sandwiched and sealed between the front piece 1a and the rear piece 1b of the container body 1 at the upper edge thereof. As shown in FIG. 2, the upper ends of the gussets 5a and 5b are heat-sealed and attached to one surface X of the mounting portion 2a of the mouth 2 together with the front piece 1a on one side. 2 is attached to the upper end of the container body 1. In this case, the gussets 5a and 5b are formed with a folding length so as to have a predetermined width d (about 2 to 10 mm) between the end portions.

When the mouth 2 and the container body 1 are attached by heat sealing, the mouth 2 is
By preheating at about ° C and then heat-sealing with the container body 1, heat-sealing can be performed more reliably.

When the container 10 having such a structure is used, for example, as a beverage container, first, the lid 2 is opened from the mouth 2.
2c is removed and the beverage inside the container body 1 is sucked out from the spout 2b of the mouth 2 or poured into a cup or the like for drinking.
At this time, the container body 1 is used while grasping the outer surface thereof by hand.

Therefore, when the container body 1 is directly gripped by the hand or the like, the support piece 6 projecting from the outer surface of the container body 1 comes into contact with the hand. The support piece 6 is formed by bending the sheet body. Because the cut edge of the sheet body does not touch the hand, the hand hurts when grasped,
There is no risk of injury. Also, even if there is a portion of the overlapping portion 9 where the seal is insufficient, since the portion is bent, the internal solution does not leak therefrom.

Further, when the container body 1 is self-standing, the gussets 5a and 5b can be self-standing with a large bottom area and stability because the width of the gussets 5a and 5b is wide. Also, since the support pieces 6 projecting from the corners 4 are heat-sealed,
It has a predetermined strength, supports the container body 1 to be self-supporting, and can more stably self-support. In particular, in the case of a container for storing a liquid such as a beverage, the inside of the beverage or the like may be spilled when the container falls down, and therefore, the container 10 that can stably stand alone is suitable.

Further, the mounting portion 2a of the mouth portion 2 and the rear piece 1b of the container body 1 are heat-sealed on the entire surface, so that the sealing performance by heat sealing is improved, and the front piece 1a of the container body 1 also has both gussets 5a, 5a. 5b between the front ends of the
Since 1a and the mouth portion 2 are directly heat-sealed, there is almost no possibility that a non-sealed portion such as a pinhole is generated. Therefore, it is possible to reliably maintain the sealing between the mouth 2 and the container body 1 to prevent leakage, and at the same time, to connect the gussets 5a and 5b to the mouth 2
And the thickness of the container body 1 can be increased.

In the above embodiment, the mouth 2 having the cylindrical spout 2b at the center of the attachment 2a is used as the mouth 2 to be attached to the container body 1. However, the shape, material, etc. of the mouth are used. The present invention is not limited to this. For example, a configuration in which a mouth with a straw attached thereto is attached below, the lid is removed, and the inside beverage or the like is sucked from the mouth through the straw can be adopted. .

Further, in the above embodiment, the container body 1
Is formed from one sheet so that the overlapping portion of the sheet body is located at one corner 4, and the overlapping end is bent at the corner 4 to form the support piece 6. The portion may not be located at the corner portion 4, but may be located at, for example, the front and rear side pieces 1 a and 1 b of the container body 1 and the central portion of both gussets 5 a and 5 b.

It is not a condition that all of the corners 4 are formed by bending the sheet body. For example, as shown in FIG. 7, the overlapping portion of the sheet body protrudes outward on one corner 4a. The other three corners 4 may be the container body 1 formed by bending the sheet body.

[0028]

As described above, according to the present invention, since the mounting portion of the mouth and the sheet piece on the other side of the container body are heat-sealed on the entire surface, the sealing performance by heat sealing is improved, and the tips of both gussets are improved. Since the sheet piece and the mouth portion on one side of the container body are directly heat-sealed over a predetermined width between the portions, there is almost no possibility that a non-sealed portion such as a pinhole is generated. Therefore, it is possible to reliably prevent leakage by reliably maintaining the sealing between the mouth and the container body, and to increase the thickness of the container body by folding the gusset to the position of the mouth.
