A sanitary container has a hollow cavity for storing a product in cleanliness. A wall portion of the container has a laminated structure of an inner layer and an outer layer. The outer layer is made of a cyclic olefin polymer containing at least one pigment selected from the group consisting of C.I. Pigment Yellow 147, C.I. Pigment Yellow 180 and C.I. Pigment Yellow 181 and added therein. The inner layer is made of a cyclic olefin polymer free of the at least one pigment. The sanitary container is superb in pigment dispersion (ultraviolet ray blocking property), is free of troublesome contamination of its content with pigment particles, and is also excellent in impact resistance strength, gas barrier properties and interface bonding. |
