FIG. 1 is a longitudinal sectional view showing a first embodiment of a container according to the present invention. The container 1 is provided with an annular projecting portion 21 provided on the inner surface on the bottom side which is formed into a perfect circular cross section. A desiccant α such as silica gel is stored in a cylindrical bottomed container body 2 made of a resin and a molded container body 31 having a flange portion, and then a moisture-permeable packaging lid 32 is attached to the molded container body 3.
A molding container 3 in which an opening of the molding container main body 31 is sealed by heat bonding at a flange portion 1; and a lid 4 made of synthetic resin, wherein the flange portion of the molding container 3 has the cylindrical shape with the bottom. The molding container 3 is inserted into the bottomed cylindrical container main body 2 from the opening so as to come to the opening side of the container main body 2, and the flange portion of the molding container 3 is formed of the bottomed cylindrical container main body 2. In a state in which the annular projecting portion 21 provided on the inner surface is passed, the flange portion of the molding container 3 is locked by the annular projecting portion 21 of the bottomed cylindrical container body 2 so that the molding container 3 is closed. It is positioned and placed on the bottom of the cylindrical container main body 2, and the opening of the bottomed cylindrical container main body 2 is closed by the lid 4,
The space on the opening side in the bottomed cylindrical container body 2 forms a content storage chamber A. Of course, before closing the opening of the bottomed cylindrical container body 2 with the lid 4, contents that dislike moisture are stored in the contents storage chamber A.

The bottomed cylindrical container body 2 and the lid 4 are molded by an injection molding method, and the material to be provided for this can be molded by an injection molding method and is a synthetic material having excellent water vapor barrier properties. The resin is not particularly limited as long as it is a resin. For example, high-density polyethylene, polypropylene, or the like is suitable in consideration of cost, productivity, and the like. The molding container body 31 constituting the molding container 3 is not particularly limited as long as it is a synthetic resin sheet that can be formed into a sheet by a vacuum / pressure molding method, but is preferably a rigid synthetic resin sheet. Examples of the sheet include a polystyrene (high impact polystyrene) sheet, a rigid polyvinyl chloride sheet, and a polypropylene sheet. The packaging lid 32 constituting the molded container 3 is not particularly limited as long as it has a moisture-permeable property and can seal the opening of the molded container body 31. In consideration of productivity, it is preferable that the sealing can be performed by heat bonding at the flange portion of the molded container main body 31. Depending on the material used for the molded container main body 31, for example, the molded container main body 31 is made of a polypropylene sheet. When the packaging lid 32 is used, the packaging lid 32 may be a microporous polypropylene sheet (trade name: NF sheet manufactured by Tokuyama Corporation). A configuration in which a heat sealant is applied in a part shape so as to correspond to the flange portion of the molded container body 31 may be employed. With this configuration, the heat sealing agent is appropriately selected depending on the material used for the molded container body 31, and the lid for packaging can be sealed by heat bonding with the molded container body 31 at the flange portion. The body 32 can be used. In the case where a paperboard or an open-cell foam sheet (a resin to be used, for example, a closed-cell foam sheet may be used in the case of polystyrene) may be used as the packaging lid 32, the packaging lid 32 may be used. Can be sealed with a hot melt adhesive or the like.

Next, a mechanism for closing the opening of the bottomed cylindrical container body 2 will be described. In this mechanism, the desiccant α contained in the moisture-permeable molding container 3 absorbs the moisture in the air sealed in the contents storage chamber A and the moisture in the air intruding from the outside, and the inside is absorbed.
