[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desiccant-filling packaging material, and more particularly to a desiccant-filling packaging material used for refilling a desiccant.

[0002]

2. Description of the Related Art For the purpose of dehumidifying a place where moisture is likely to be generated, such as a closet, for example, a desiccant and a dehumidifier are filled in a packaging material to remove moisture. And in recent years,
From the viewpoint of resource saving and environmental protection, a type of moisture removal that can replace a used desiccant with a new desiccant instead of disposable has been developed. Such a replaceable type of dehumidifier is used for an outer container to be used continuously, and a desiccant-filling packaging material that is used by being placed in the outer container and replaced with a new one after use. It is composed of FIG. 4 is a perspective view for explaining an example of a conventional desiccant-filling packaging material used for removing moisture. As shown in FIG. 4, the desiccant-filling packaging material 11 has a mesh 12a at a lower portion. Tray 12 for holding desiccant
And a microporous film 14 provided to seal the opening of the tray 12 and the opening of the tray 1
2 and a plastic film bag 16 joined to the upper outer wall.

[0003]

[Problems to be Solved by the Invention] However, the conventional desiccant-filling packaging material requires tray molding,
The melt bonding process of a relatively hard tray and a flexible plastic film bag is required separately from the tray forming process and the bag forming process, and the manufacturing cost increases because this process is complicated. There was a problem of doing. There is also a problem that the fine desiccant falls through the mesh provided on the tray to the plastic film bag.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a desiccant filling packaging material which is easy to manufacture and can surely fill and hold a desiccant. .

[0005]

In order to achieve such an object, the present invention provides a method of fusing the edges of a rectangular film.
Another film is inserted into the opening at one end of the cylindrical object
And a bottomed bag body having a bottom formed by fusing, and the other end of the bag body
A microporous film provided in the opening on the side ,
The bag had a perforated separator provided in the bag so as to divide the bag into the microporous film side and the bottom side.

[0006]

The holding space for the desiccant is constituted by the upper part of the bag, the microporous film provided at the opening of the bag, and the perforated separator. The desiccant filled and held in the holding space is: Water vapor in the outside air that has passed through the microporous film is absorbed and liquefied, and the liquefied desiccant passes through the perforated separator and accumulates in the lower part of the bag.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of the desiccant filling packaging material of the present invention, and FIG. 2 is a front view. 1 and 2
, The desiccant-filling packaging material 1 has an opening 3 and a bottom 4
, A microporous film 6 provided to seal the opening 3 of the bag 2, and a bag 2
And a perforated separating membrane 8 provided inside the bag body 2 so as to divide the upper and lower parts of the bag body.

The bag 2 is a square film 2 having no moisture permeability such as a nylon film or a polyethylene film.
a, 2a are opposed to each other, the opposite end sides thereof are fused together, and the end side of the two-folded rectangular film 4a, also having no moisture permeability, is fused to one opening to form a bottom portion 4. Things . The thickness of the film 2a is usually 40 to 100
It is preferably about μm.

The microporous film 6 is a film having fine pores formed of a resin such as polyethylene or polypropylene to which a filler is added, and has a property of transmitting water vapor and air but not passing water. As such a microporous film 6, a known microporous film can be used. In the illustrated example, the square microporous film 6 folded in half has a bent portion 6a at an end thereof, and the bag body 2 is bent.
It is fused to the opening 3 facing inward so as to face inward. The bent portion 6a of the microporous film 6
May be fused to the inside of the bag body 2 so as to face the outside of the bag body 2.

As the perforated separation membrane 8, a material having water-permeable holes such as a nonwoven fabric can be used.
In the illustrated example, the square perforated isolation film 8 which is folded in two is fused to the inside of the bag body 2 so that the bent portion 8 a of the isolation film 8 faces the microporous film 6. As a result, the bag body 2 is divided into the microporous film 6 side and the bottom 4 side via the perforated separator 8.
The upper space of the bag 2, the microporous film 6 provided in the opening 3 of the bag, and the perforated separator 8 constitute a holding space A for the desiccant 9. Further, the bag body 2 below the perforated isolation membrane 8 becomes a space B for storing a liquefied desiccant. The perforated insulating film 8 may be fused into the bag body 2 so that the bent portion 8a of the perforated insulating film 8 faces the bottom portion 4. Since the perforated isolation film 8 does not allow the fine powder of the desiccant to pass through, the desiccant 9 is reliably held in the holding space A.

As the desiccant 9, besides a desiccant such as calcium chloride, a fungicide, a deodorant and the like can be used. FIG. 3 is a view showing an example in which the desiccant 9 is filled in the desiccant filling packaging material 1, and only one end side (left side in the illustrated example) of the opposed films 2a, 2a is left without being fused.
The drying agent 9 is filled in the direction of the arrow, and then the above-mentioned one end is fused.

As described above, in the desiccant filling packaging material of the present invention, the bag, the desiccant holding space A, and the liquefied desiccant storage space are formed by using the bag film, the microporous film and the perforated separator. Since B is formed, a conventional tray is not required. In addition, the joining step of the relatively hard tray and the bag body is inevitably omitted, and the step is simplified.

In FIGS. 1 to 3 described above, the hatched portions indicate the fused regions. Next, the present invention will be described in more detail with reference to experimental examples. (Experimental example) Nylon (15
μ) / polyethylene (40μ) dry laminated film, NF sheet (manufactured by Tokuyama Soda Co., Ltd.) as a microporous film, and Heatron Paper (nonwoven fabric manufactured by Nippon Paper Industries) as a perforated separator. As shown in FIG. 3, only one end was formed without being fused.
After that, granules of calcium chloride as a desiccant were placed in the space between the microporous film and the perforated separator, and the opening was fused to form a desiccant-filling packaging material as shown in FIG. . This desiccant-filling packaging material takes in and absorbs water vapor in the outside air through a microporous film, and the liquefied desiccant passes through the perforated separator and enters a bag below the perforated separator. Accumulated.

[0014]

As described in detail above, according to the present invention, the bag, the holding space for the desiccant and the storage space for the liquefied desiccant are formed by using the bag film, the microporous film and the perforated separator. Since they are formed at the same time, the conventional tray is not required, and the joining step of the relatively hard tray and the bag is inevitably omitted, thereby simplifying the steps.
