Abstract

A container for a sanitary article capable of stably preserving, while making sure of sanitary property for a long time, materials legally provided by the Japanese Pharmacopoeia, the Food Sanitation Act, etc., for example, pharmaceuticals such as vaccine, antiobiotics, vitamines, sugars, amino acids, electrolytes, etc., materials needing sanitary property, such as nutriments, transfusion liquids, cosmetics, seasonings and other foods is provided. This container comprises a material containing a resin formed of a cyclic olefin compound or a bridged polycyclic hydrocarbon compound, as a polymeric component.

Claims

1. A container for a sanitary article wherein at least the inner surface thereof is made of a resin material consisting essentially of a resin formed from at least 30%, by weight, based upon the weight of the resin, of a cyclic olefin compound having at least five carbons or a bridged polycyclic hydrocarbon compound, as a polymeric component, said resin having a softening point of at least 130°

C. and a bromine number of at most 1.

2. The container for a sanitary article as claimed in claim 1, wherein the cyclic olefin compound is at least one member selected from the group consisting of monocyclic olefin compounds, alkyl derivatives of monocyclic olefin compounds, and acrylate derivatives of monocyclic olefin compounds.

3. The container for a sanitary article as claimed in claim 1, wherein the bridged polycyclic hydrocarbon compound has at least one unsaturated bond in the ring or in a substituent on the ring.

4. The container for a sanitary article as claimed in claim 1 wherein the resin formed of a cyclic olefin compound or a bridged polycyclic hydrocarbon compound, as a polymeric component, contains at least one member selected from the group consisting of lower olefins, aromatic compounds, vinyl monomers of lower olefins and vinyl monomers of aromatic compounds, as a copolymeric component.

5. The container for a sanitary article as claimed in claim 1, wherein the container has at least one laminated layer on the surface thereof, the laminated layer consisting of a material containing the resin formed of a cyclic olefin compound or a bridged polycyclic hydrocarbon compound, as a polymeric component.

6. The container for a sanitary article as claimed in claim 5 wherein the material containing the resin formed of a cyclic olefin compound or a bridged polycyclic hydrocarbon compound, as a polymeric component, is laminated on the inner surface of a glass container, metallic container or plastic container.

7. The container for a sanitary article as in claim 5, wherein the resin is a copolymer of a cyclic olefin compound or a bridged polycyclic hydrocarbon compound and at least one member selected from the group consisting of lower olefins, aromatic compounds, vinyl monomers of lower olefins and vinyl monomers of aromatic compounds.

8. The container according to claim 7, wherein the resin is a mixture of said copolymer and at least one member selected from the group consisting of olefinic resins and synthetic rubbers.

9. The container according to claim 1 which is made entirely of a copolymer of a cyclic olefin compound or a bridged polycyclic hydrocarbon compound and at least one member selected from the group consisting of lower olefins, aromatic compounds, vinyl monomers of lower olefins and vinyl monomers of aromatic compounds.

10. The container for a sanitary article as claimed in claim 1, wherein the cyclic olefin compound from which the resin is formed is a monocyclic olefin compound.
