Description

[Detailed Description of the Invention] The present invention relates to a package for a desiccant that absorbs moisture in the air, which maintains an airtight state before use and is capable of absorbing moisture during use.

As a package for a drug that absorbs moisture or oxygen in the atmosphere, such as an oxygen scavenger or a desiccant, the drug 1 is first packaged in an inner bag 2 made of a breathable material, as shown in FIG. It was common to have a double bag structure in which the bag was further sealed with an outer bag 3 made of a non-breathable material.

Therefore, when it is used, the outer bag must be opened and the inner bag taken out, which not only requires the use of more packaging material than necessary, but also makes handling of the bag complicated.

In order to improve this drawback, one side of the bag for packaging the medicine 1 is made of a non-breathable material 4, and the other side is made of a breathable material 5 such as a non-woven fabric and a non-breathable material 6.
The material was made of a laminated material with a seal portion 7 formed around the periphery, and the adhesive strength between the breathable material 5 and the non-breathable material 6 was adjusted to facilitate peeling.

However, if these structures were used as they were for a desiccant, there was a risk that the moisture absorbed by the desiccant would turn into water and seep out of the bag as the desiccant was used, making it unusable.

Therefore, the desiccant was used by being stored in a plastic molded container 8 having a ventilation hole 9 in the upper part, as shown in FIG.

This molded container 8 was sealed with a non-breathable material before use, and was opened before use.

In view of these conventional techniques, the present invention aims to provide a bag-shaped desiccant package that is easy to use.

The present invention will be explained below.

The present invention, as shown in FIGS. 4 and 5,
A side wall 10 made of a material that is non-ventilated, non-water permeable and has heat-sealing properties on the inside, and a cut 12 formed approximately in the center of the same material as the bottom member 11 folded in half;
It consists of a side wall 15 with an accommodating part 13 at the bottom and a peeling part 14 at the top, and a breathable material 16 made of a non-water permeable, air permeable film that reaches below the cut 12 of the side wall 15 is provided inside the peeling part 14. A desiccant packaging body in which the desiccant 17 is housed and sealed in a bag provided with sealing parts around the side walls 10 and 15 and the bottom member 11, and around the area where the breathable material 16 and the side wall 15 come into contact. It is.

Here, the seal between the air permeable material 16 and the side wall 15 in the seal portion is such that the seal strength between the air permeable material 16 and the peeling portion 14 is weak and can be peeled off, and the gas permeable material 16 and the housing portion 13 are sealed. Increases strength and makes peeling difficult.

The breathable material 16 is non-water permeable and breathable, such as a porous plastic film having numerous small pores with a diameter of 0.02 to 0.4 .mu.m.
Plastic film has small holes with a diameter of 0.02.
With holes of ~0.4μ, the porosity is 20% or more,
It is preferably made of materials such as polypropylene, high-density polyethylene, polyester, etc. with a content of 30% or more.

The breathable material 16 is not only a single film that is non-water permeable and breathable, but also a laminated material in which a resin layer having heat sealability is provided on the entire surface or part of the film within a range that does not impede air permeability. good.

Since the desiccant package of the present invention has the above-mentioned structure, it can reliably maintain airtightness before use, and can easily be removed by peeling off the peeled part of the side wall from the breathable material during use. Provides breathability.

In addition, although the bag is a bag, it can stand on its own, and even if it falls over, there is no risk of absorbed water leaking out, making it safe to use. The fact that it can be folded flat is also easy to use.

Furthermore, if the structure is such that the size of the peeling part can be changed, the moisture absorption time of the desiccant can be changed as appropriate.
