Description

[Detailed description of the invention] This invention relates to a standing pouch used for packaging articles.

As shown in FIGS. 1 and 2, the standing pouch has a cylindrical shape including a front body piece 2, a back body piece 3, and a bottom piece 4, and the bottom piece 4 has an edge 9.
It is attached to the front body material piece 2 and the back body material piece 3.
Such a standing pouch 1 can contain contents such as fluids and powders, and can be stored, displayed, and exhibited in a three-dimensional shape, and has a three-dimensional shape with flexibility and a standing mechanism. Its use as a packaging material with a display effect is increasing.

When removing the contents from the standing pouch 1, the pouch is torn open using the notch 5. On the other hand, standing pouch 1
When not in use, the front body material piece 2 and the back body material piece 3 are stacked in close contact with each other, as shown in FIG.
In addition, the bottom material piece 4 is folded with the center portion as an apex 8 and is located between the front body material piece 2 and the back body material piece 3. When filling this standing pouch 1 with contents, air is blown from the direction of arrow B between the front body material piece 2 and the back body material piece 3 to fill the standing pouch 1. is inflated as shown in Figure 4 and then filled with contents. However, when the standing pouch 1 is inflated by this air blowing, the bottom material pieces 4 may not open evenly, resulting in so-called bottom opening failure. This failure to open the bottom occurs due to a combination of three factors: the bag shape of the standing pouch, the packaging material composition, and the filling mechanism, and the bottom material piece 4 is in close contact with the front body material piece 2 and the back body material piece 3. If sufficient gaps 6 and 7 are not formed on both sides of the bottom material piece 4 for air to be blown in, or if the gaps 6 and 7 are not evenly formed and air is blown into one side. It happens often.

This idea was made in view of the above circumstances, and it prevents the bottom material pieces and the body material pieces or the bottom material pieces from coming into close contact with each other, and also distributes blown air evenly around the folded bottom material pieces. It is an object of the present invention to provide a standing pouch that can be easily inserted into the pouch and eliminate the problem of bottom opening.

For this purpose, the standing pouch of the present invention includes at least two pieces of body material, and is folded between the two pieces of body material and is attached to the body piece at the edge. It is characterized by comprising a piece of bottom material attached to the bottom material, and an emboss is formed on at least a portion of the piece of bottom material.

The details of this invention will be explained below with reference to the drawings showing one embodiment.

In FIG. 5, reference numeral 10 denotes a standing pouch. the vertex 18
It consists of a substantially circular bottom material piece 14 that is folded in and arranged as a front body material piece 2 and a back body material piece 3.
The lower end of the bottom member 14 is adhesively sealed to the circumferential end surface 19 of the bottom piece 14 to form a container body. The bottom material piece 14 is embossed with 1 as shown in FIGS. 5 and 6.
5 is formed. Commercially available materials can be used for the front body material piece 2, the back body material piece 3, and the bottom material piece 14.

In the standing pouch 10 configured in this way, when the standing pouch 1 is not in use, the bottom material piece 14 is folded between the front body material piece 2 and the back body material piece 3, and the Even when the bottom material piece 14 is in contact with the front body material piece 2 and the back body material piece 3, since the uneven embossing 15 is formed on the surface of the bottom material piece 14,
The bottom material piece 14 does not come into close contact with the front body material piece 2 and the back body material piece 3, and there are many gaps formed by the embossing 15 between them, and the body material pieces also do not come into close contact with each other. . Therefore, when air is blown into the standing pouch 1 as shown by arrow B prior to filling the contents, the air flows into the gap formed by the embossing 15 and the bottom material piece 14 is The front body material piece 2 and the back body material piece 3 can be peeled off easily, and the bottom material pieces 14 can be easily peeled off from each other, and even gaps 1 can be formed on both sides of the bottom material piece 14.
6 and 17 to promote good bottom opening as shown in FIG.

As is clear from the above explanation, according to this invention, the gap at the bottom of the standing pouch is increased to prevent the bottom material pieces and the body material pieces or the bottom material pieces from coming into close contact with each other, and to fold in the blown air. It is possible to obtain a standing pouch that can easily fit around the bottom material piece and can eliminate the problem of opening the bottom.
