DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing and deodorizing bag having both a deodorizing effect and a deodorizing effect, and more particularly to a deodorizing and deodorizing bag in which a deodorizing sheet and a deodorizing sheet are enclosed in an outer package.

[0002]

2. Description of the Related Art In recent years, various types of deodorizing and deodorizing devices have been provided in a garbage container or a refrigerator. For example, a deodorizing sheet and a deodorizing body are stored in a box-shaped container or a deodorizing device. There are various types such as a type in which an odor sheet is attached to the back of a trash can lid. Generally, a deodorant sheet is for adsorbing odor components such as ammonia and hydrogen sulfide, and is obtained by integrating a deodorant with a breathable sheet such as a nonwoven fabric and forming the sheet into a sheet. The deodorizing body is for dispersing or adsorbing odorous component gases such as ethylene gas, and is generally configured by storing a powder or granule deodorizing agent such as activated carbon in a gas-permeable exterior body. It is a target.

[0003]

However, since the properties of the deodorizing agent mainly composed of activated carbon are powdery or granular and it is difficult to form a sheet, it has conventionally been used for a breathable exterior body. It was stored and used. For this reason, when the deodorizing body is used in combination with the deodorizing sheet to form a deodorizing deodorizer, the deodorizing deodorizer itself has to be formed in a box shape, or becomes bulky. Even when the container is a bag, when it is used in an upright state, the deodorant is unevenly distributed downward, which is disadvantageous in that the efficiency is poor. In view of the above, the objects of the present invention are:
An object of the present invention is to provide a compact deodorizing and deodorizing bag in which a deodorizing body is formed into a sheet and the deodorizing sheet and the deodorizing sheet are integrally enclosed with an exterior body.

[0004]

Means for Solving the Problems As a result of intensive studies, the inventors of the present invention have found that the above objects of the present invention are as follows: (1) The deodorizing sheet and the deodorizing sheet are enclosed in an exterior body having air permeability on at least one side And (2) the deodorizing sheet is formed by stacking a heat-fusible nonwoven fabric on a non-heat-fusible nonwoven fabric, Is disposed, the non-heat-fusible nonwoven fabric is directly overlaid on the deodorant, or the non-heat-fusible nonwoven fabric is superimposed on the heat-fusible nonwoven fabric, and thermocompression-bonded to remove the deodorant. The deodorizing / deodorizing bag according to the above (1) or (3) the deodorizing sheet is fixed to the heat-fusible nonwoven fabric and / or the non-heat-fusible nonwoven fabric. Disperse and disperse powdery or granular deodorant and hot-melt adhesive on nonwoven fabric,
It has been found that this is achieved by the deodorizing / deodorizing bag according to the above (1), which is obtained by laminating a non-heat-fusible nonwoven fabric thereon and then performing thermocompression bonding.

According to the present invention, the deodorizing and deodorizing bag itself can be made compact, and handling becomes extremely easy. In addition, the powdery or granular deodorant can be reliably formed into a sheet, and can be easily combined with a deodorant sheet. Further, the deodorizing and deodorizing bag of the present invention is extremely suitable, for example, when it is installed in the back of a garbage container, in a refrigerator, or inside furniture such as a clog box or in any other place where deodorization and deodorization is intended.
