Abstract
A sanitary container is composed of a base container made of a cyclic olefin polymer or its hydrogenation product and an inorganic coating formed on a surface of said base container. The sanitary container can be produced by forming the inorganic coating on the surface of the base container by plasma CVD.
Claims6
A sanitary container comprising:
- a base container made of a ring-opened homopolymer of a cyclic olefin monomer or a hydrogenation product thereof;
- and
- an inorganic coating formed on a surface of said base container, wherein said inorganic coating is a diamond-like carbon coating, a modified carbon coating, a titanium oxide coating, a silicon oxide coating, a silicon carbide coating, or a silicon nitride coating and has a thickness in a range of 0.1 to 1 .mu.m.
A process for the production of a sanitary container, which comprises forming by plasma CVD an inorganic coating on a surface of a base container made of a ring-opened homopolymer of a cyclic olefin monomer or a hydrogenation product thereof, wherein said inorganic coating is a diamond-like carbon coating, a modified carbon coating, a titanium oxide coating, a silicon oxide coating, a silicon carbide coating, or a silicon nitride coating and has a thickness in a range of 0.1 to 1 .mu.m.
