Description

  The present invention relates to a packaging container containing a desiccant.

  When pharmaceuticals, cosmetics, foods such as confectionery and seasonings, electronic parts, etc. that require moisture resistance are stored in the packaging container, the desiccant is also placed in the packaging container. When the desiccant is granular, the desiccant is put into a small flat bag made of a material having air permeability. When the desiccant is solid, the desiccant is enclosed in a packaging container as it is.

  The desiccant in such a form not only occupies a large capacity of the contents of the packaging container but also has the trouble of avoiding the desiccant every time the contents are removed from the packaging container. In addition, depending on the type of desiccant, the moisture-proof effect is too strong, and when this comes into contact with the contents, partial discoloration or alteration may occur in the contents. Furthermore, when the desiccant is in a solid form, it may be difficult to distinguish it from the desiccant, depending on the food that is the content, and there is a risk of accidental eating.

By the way, in order to prevent the desiccant and the contents from coming into contact with each other, it is made of a thermoplastic synthetic resin containing a desiccant inside the mouth portion of the packaging bag body made of the thermoplastic synthetic resin containing the contents before sealing. The mouth of the sachet is open and the mouth side is inserted, and the mouth of the wrapping bag body is fused, so that the sachet and the wrapping bag body are in communication and the sachet and the packaging bag body are integrated. This is disclosed in Patent Document 1 below. However, this is complicated to manufacture and the mouth of the sachet remains open, so that the desiccant may jump out of the sachet and enter the packaging bag body and come into contact with the contents of the packaging bag body.
