Description

Pouch with split packaging space {POUCH HAVING SEPARATED PACKAGING SPACE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouch having a divided packaging space, and more particularly, to a pouch having a divided packaging space having a plurality of divided packaging spaces and having a divided packaging space in which packaging contents can be communicated when necessary.

Pouches made of film-type wrapping paper are widely used for hermetic packaging of cosmetics, medicines, and the like, and have recently been used as packaging means for mask packs.

The pouch 100 according to the related art has a structure in which a seam 130 is formed at an edge portion of the pouch 100 to have a single packaging space 140 as a pouch in which the pack 150 is packaged. That is, the pouch 100 is composed of a lower film 110 and an upper film 120 made of a sealing packaging film, the edge portion of the lower film 110 and the upper film 120 is compressed by a thermocompression method A suture line 130 is formed. The cutout 132 is formed at one side of the suture line 130 so that the pouch 100 can be easily opened. Of course, the pack 150 is built in the packaging space 140 inside the suture line 130.

Meanwhile, the pack 150 packaged in the pouch 100 has a structure in which a cosmetic having a predetermined viscosity is applied to a nonwoven fabric. Recently, various functional materials such as vitamin C and retinol may be added to enhance the functionality of the pack 150. However, some of the functional materials are substances that change their properties or are less functional when exposed to moisture-containing ingredients in cosmetics for a long time.

However, since the conventional pouch is manufactured to have only a single packaging space, the pack in the state of the finished product is packaged as it is, and there is a limit to maximize the effect of the functional material. In addition, since the functionality of the functional material decreases over time, the shelf life of the pack is also short.

Of course, with a pouch in which the functional material has been removed and a pouch in which only the functional material is separately packed, when the pack is used, the pouch in which the pack is packaged is first opened, and then the pouch in which the functional material is packaged, and the functional material is added to the pack. It is also possible to apply and use, but in this case, there is an inconvenience of having two types of pouches separately.

And after opening each pouch containing the pack and the functional material, there is an inconvenience that the user has to apply the functional material directly to the pack.

In order to solve the problem, a pouch having multiple packaging spaces has been proposed. Pouches having a conventional multi-package space are completely sealed by sealing the edges with respect to the upper film and the lower film whose adhesive surface is composed of polyethylene (PE) or polypropylene (PP) film, and in the case of a seam that divides the packaging space When the pressure is applied to the suture surface is characterized in that it is formed in a semi-thermal compression method.

The upper film 220 may be configured in a shape and size corresponding to the lower film 210, and may be manufactured as a sealing packaging film in the same manner as the lower film 210. As described below, in the state in which the upper film 220 is disposed on the upper side of the lower film 210, at least one corresponding region of the upper film 220 and the lower film 210 is sealed to each other to form the pouch 200. It will form a packaging space in the.

An easy peel layer 216 and 226 may be included on at least one surface of the lower film 210 and the upper film 220. The easy-fill layers 216 and 226 are configured to have a sealing property that does not have a large variation in peel strength due to a change in thermocompression temperature when performing a single thermocompression, and has a sealing property that can be easily opened by an external force. It can be implemented using an easy peel film known in the art. Alternatively, in some embodiments, the easy peel layers 216 and 226 may be formed by applying a predetermined coating agent having an easy peel function on at least one surface of the lower film 210 and the upper film 220. Such coatings are a type of adhesive composition, and may include, for example, resin solids, maleic acid anhydride, chlorinated polyolefins, nitrocellulose resins, and the like.

In one embodiment, as shown in FIG. 3, the lower film 210 and the upper film 220 may include easy peel layers 216 and 226 on one surface disposed to face each other to form a packaging space. .
