Description

Zipper pouch with top entrance and side exit structure

[0001] The present invention relates to a zipper pouch having a top inlet and a side outlet structure, and more particularly, to a zipper pouch having a top inlet and a side outlet structure in which a filling inlet and a product opening inlet are different.

[0002] Pocket Zipper Pouches are one of the most popular and modern packaging materials used in the retail industry, also known as tab removal zippers or front opening zippers.

[0003] Pocket zipper pouches effectively increase opening, improving packaging efficiency, making it easy to fill contents, and ensuring a perfect top seal after filling.

[0004] Typically, a zipper pouch is structured such that after filling the contents, the top is sealed, an easy cut is formed at the bottom of the top, and a zipper is placed at the bottom of the easy cut.

[0005] The zipper pouch has a single entrance / exit for filling the contents (manufacturer) and putting the contents in / out (consumer).

[0006] In such cases, there is a problem that when the manufacturer fills the contents, the zippers are formed in male and female pairs, which often results in the zippers being filled, making it difficult to fill the contents and causing product defects.

[0007] Recently, considering the problems of such zipper pouches, pocket zipper pouches are widely used. As described above, the pocket zipper pouch is structured so that the entrance for filling the contents and the entrance for using the contents by the consumer are formed through different paths.

[0008] However, due to the somewhat complex pouch structure, the production cost increases and there are problems in use.
