Description

[Detailed Description of the Invention] The present invention relates to a novel sheet material packing having hygroscopic properties, which can dehumidify the inside of a container without applying a hygroscopic material to the inside of the container or the mouth of the container.

Conventionally, to dehumidify the inside of a container, a packaged Sho moisture material is inserted into the container, an inner stopper filled with a moisture absorbent material is inserted into the mouth of the container, or a moisture absorbent material is inserted into a moisture absorbent storage area formed on the inner surface of the cap. However, even in the first case, a gasket is required, and as a result of various actual and experimental research, the inventor applied a moisture-absorbing material to the gasket, making it unnecessary to use a separate moisture-absorbing material. We came up with this idea that does not.

To explain the present invention with reference to the drawings below, two pieces of nonwoven fabric 1
are laminated, the abutting surfaces of the two nonwoven fabrics 1 are partially thermally bonded with a large number of heat-adhesive synthetic resin powders 2, and a powdered moisture absorbent material 3 is held between the abutting surfaces of the two nonwoven fabrics 1. That's what happens.

The present invention is for sheet or long sheets with a thickness of 0.1 to 5.0 mm.
A mixture of heat-adhesive synthetic resin powder 2 such as polyethylene with a particle size of 10 to 500 μm and powdered moisture absorbent material 3 with a particle size of 10 to 300 μm in an appropriate ratio is sprinkled onto the upper surface of the nonwoven fabric to an appropriate thickness. , the above-mentioned nonwoven fabric is superimposed on the mixture, and then heated and pressed from the front and back to melt the thermoadhesive synthetic resin powder 2, and the nonwoven fabrics on both sides are partially bonded in many dots, and the powdered moisture absorbent The material 3 is held between the front and back nonwoven fabrics, and the resulting packing material is punched out to an appropriate size to form the packing 4.

In the figure, 5 is a container, 6 is a cap, and if necessary, the nonwoven fabric 1 can be made of three or more layers and the moisture absorbing material layer can be made of two or more layers.

In the present invention, a plurality of nonwoven fabrics 1 are laminated, the contact surfaces of the nonwoven fabrics 1 are partially thermally bonded with a large number of heat-adhesive synthetic resin powders 2, and a powdery moisture-absorbing material 3 is held between the contact surfaces of the nonwoven fabrics 1. When applied to the inner surface of a cap 6 attached to a container 5, the inside of the container 5 is kept dry by the powdered hygroscopic material 3 contained in the hygroscopic material 4, and the powdered hygroscopic material 3 It does not fall into the container 5, does not cause contamination by the powdered moisture absorbing material 3 of the filled material, and also has the effect of being a packing.
