Abstract

A laminated sheet or a container includes: an absorbing layer absorbing at least one of liquid and gas; a reinforcing layer laminated on the absorbing layer with an adhesive layer interposed therebetween; an aluminum layer laminated on the reinforcing layer with an adhesive layer interposed therebetween; and a barrier layer laminated on the aluminum layer with an adhesive layer interposed therebetween and suppressing entry of at least one of liquid and gas.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a laminated sheet having a plurality of layers laminated therein, a container having a recessed holding space formed therein, and a package holding a solid preparation therein.[0003]2. Description of the Related Art[0004]A laminated sheet of this type is used for a container (a pocket product, a cover, and the like) of a medicine, for example.[0005]Medicines are taken or applied for treating a disease or an injury or for maintaining and promoting the health.[0006]Here, a powder medicine is enclosed in a thin paper bag, a thin film bag, or the like. On the other hand, a granular or capsule-shape medicine is sometimes put into production as a blister package called a PTP (Press Through Package).[0007]The blister package has a granular or capsule-shaped medicine held therein. The medicine inside can be visually confirmed from the outside through a transparent container. Then, the medicine, ...
