JPH0741010A - Stand pouch - Google Patents

Abstract

PURPOSE:To provide a stand pouch having an attached extracting port not interfering and suitable for housing refill liquid. CONSTITUTION:A stand pouch is composed of a pouch main body 1 composed of two body wall sheets 3, 4 faced to each other and a two-folded bottom wall sheet 5 to be pinched on the lower end of the body wall sheets 3, 4, and formed by heat sealing their peripheral edges, and an extracting port 2 attached to the bottom wall sheet 5. Since the extracting port 2 is housed in the part to be surrounded by the lower parts of the body wall sheets 3, 4 serving as leg parts, it does not interfere in displaying or handling. When liquid is refilled into a plastic bottle, the leg parts function as a guide member to the opening of the bottle, thereby the refilling operation can be easily realized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stand pouch that is self-supporting and is particularly suitable for containing a liquid.

[0002]

2. Description of the Related Art Conventionally, a self-supporting pouch (packaging bag) is made up of two opposed body wall sheets and a bottom wall sheet folded in two which is attached to the lower end portions of the body wall sheets. A so-called stand pouch formed by heat-sealing a necessary peripheral edge is widely used. That is, this stand pouch has a shape that allows the self-standing by opening the bottom of the trunk wall sheet while spreading laterally under the weight of the contents when the contents are put therein.

[0003]

Since the above-mentioned conventional stand pouch is self-supporting, it is suitable for display at the store or storage after purchase, but like the four-sided seal bag and the three-sided seal bag, Since the upper part is cut out parallel to the upper side or the upper corner part is cut out, if the contents are liquid, once the contents are opened, will the liquid inside be poured out all at once? Alternatively, when the liquid remains, the opening end has to be closed with a rod-shaped clip or the like, and there is a problem that handling after opening is troublesome. Further, when the content is a refilling liquid such as a detergent, there is a problem that it is not possible to transfer the cut spout into a plastic bottle or the like. Therefore, it is conceivable to attach a spout to the body wall sheet, but since the spout projects laterally, there arises a problem that it becomes an obstacle during filling and handling. Also, the operation of transferring to a plastic bottle or the like is not so easy.

The present invention has been made in view of the above problems, and it is an object of the present invention to prevent the attached spout from interfering and to store a refilling liquid. Another object is to provide a suitable stand pouch.

[0005]

In order to achieve the above object, the stand pouch of the present invention comprises two opposing body wall sheets and a folded bottom wall sheet sandwiched between the lower ends of the body wall sheets. It is characterized in that it consists of a self-supporting pouch body formed by heat-sealing the necessary peripheral edges thereof, and a spout attached to the bottom wall sheet.

[0006]

In the stand pouch having the above-mentioned structure, the spout is set in a portion surrounded by the lower portion of the laterally widened body wall sheet, and the spout is not exposed to the outside in appearance. Then, at the time of transfer to a plastic bottle or the like, the lower portion of the body wall sheet serves as a guide member for the mouth of the bottle.

EXAMPLES Examples will be described with reference to the drawings.

FIG. 1 is a perspective view showing a stand pouch according to an embodiment of the present invention as viewed obliquely from below. As shown in FIG. 1, the stand pouch is a self-supporting pouch body 1. It comprises a spout 2 attached to the bottom of the pouch body 1.

As shown in FIG. 2 in which the sheets are separated from each other, the pouch body 1 has a pair of body wall sheets 3 and 4 whose inner surfaces are made of a material having thermal adhesiveness, and similar to the body wall sheets 3 and 4. And a bottom wall sheet 5 which is made of the above-mentioned material and is folded in two with the surface having thermal adhesiveness facing outward, and is formed by heat-sealing necessary peripheral edges of the body wall sheets 3 and 4 and the bottom wall sheet 5. Has been done. That is, the opposing body wall sheets 3, 4
The bottom wall sheet 5 is inserted between the bottom wall sheet 3 and the bottom wall sheet 5, and the open edges of the bottom wall sheet 5 are closed and heat-sealed in a curved shape so as to be adhered. Bags are heat-sealed to bond the sides. In this case, the inner surface areas of the body wall sheets 3 and 4 facing each other through the cutout portion 5a of the bottom wall sheet 5 are heat-sealed.

Each sheet constituting the pouch body 1 has a heat-adhesive material on one side, such as polyester, cellophane, stretched polypropylene, stretched nylon, stretched vinylon, etc., and has polyethylene, polypropylene or the like on one side. An adhesive layer such as a heat-adhesive resin, an acrylic adhesive, or a rubber adhesive may be used where necessary or over the entire surface.

After the bottom wall sheet 5 is attached to the lower ends of the body wall sheets 3 and 4 to form a bag, the pouch body 1 is raised as shown in FIG. Attach 2. In this embodiment, a plastic screw-type spout 2 is inserted from the upper opening of the pouch body 1, and its flange portion 2a is heat-sealed and bonded inside the hole of the bottom wall sheet 5. In this way, the stand pouch shown in FIG. 1 is formed by mounting the spout 2 and then filling and sealing the content liquid from the upper portion of the pouch body 1.

In the above-mentioned stand pouch, the lower portions of the laterally spread body wall sheets 3 and 4 serve as legs to be self-supporting. Then, the spout 2 is set in a portion surrounded by the legs. Further, the liquid inside can be poured out by opening the spout 2 at the bottom without cutting off the upper part of the pouch body. When transferring to a plastic bottle, etc., the spout 2 can be used as a guide member and the spout 2 can be used as a bottle. Can be applied to the mouth of.

As the spout used in the present invention, an openable / closable type such as a cap type or a breakable type with a pull ring is appropriately used depending on the application of the stand pouch.

[0014]

As described above, the stand pouch of the present invention is composed of two opposing body wall sheets and a folded bottom wall sheet sandwiched between the lower ends of the body wall sheets. The pouch body consists of a self-supporting pouch body that is heat-sealed around the periphery and a spout attached to the bottom wall sheet, so that the spout is placed in the area surrounded by the lower part of the body wall sheet that serves as the legs during display. It does not hinder the handling and handling, and the content liquid can be taken out stably from the spout. In addition, when transferring to a plastic bottle or the like, the leg portion serves as a guide member for the mouth portion of the bottle, which simplifies the transfer operation, which is convenient for storing the refilling liquid.
