PURPOSE:To provide highly unsealable moldability by using a composite sheet capable of being torn up easily on a hinge part that connects a container main body and a cover body together. CONSTITUTION:A part 3 for easy tear-up in a stripe-like shape mainly composed of incompatible thermoplastic resin is formed between sheet main bodies 2a and 2b composed of a composite including heat-sealable thermoplastic resin, and thereby a composite sheet 1 is formed. Then, a container 5, composed of a container body 6 having a housing part 7 and a cover body 8 for closing an opening of the container body, is formed so that the part 3 for easy tear-up of the composite sheet 1 comes to the position of a hinge part 9 connecting the body 6 and the cover body 8. As the hinge part 9 is made up of the part 3 for easy tear up, tearing up can be made easily by hand along the hinge part 9 in taking-out of articles housed in the container, and the cover body can be detached easily from the container body. |
