PURPOSE: To obtain excellent opening property of a cap and storage property of a film by constituting the housing container of a resin material and specifying its bending modulus of elasticity.

CONSTITUTION: The container main body 1 consists of a resin material having ≤7000kg/cm2 bending modulus of elasticity, and the cap 5 consists of a resin material having ≤1200kg/cm2 bending modulus of elasticity. As for the resin material having ≤7000kg/cm2 bending modulus of elasticity, low-density polyethylene or a blended polymer of low density polyethylene and high-density polyethylene can be used. As for the resin material having ≤1200kg/cm2 bending modulus of elasticity, low-density polyethylene can be used. The container main body 1 and the cap 5 are formed by injection molding, etc., using dies. Thereby, the cap can be easily opened with small force and the container has excellent moisture preventing characteristics.
