Title:
CONTAINER FOR SANITARY ARTICLE
Document Type and Number:
Japanese Patent JP3198065
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To cut off ultraviolet rays without deteriorating transparency of a plastics container by molding a plastics material added with a pigment based on specific formulas.
SOLUTION: A particularly preferable plastic material to be used is a cycloolefinic polymer and its hydrogenated material. A pigment which is added to the plastic material to control the transmission of ultraviolet rays is shown in the following formulas I-III: 1,1'-[(6-phenyl-1,3,5-triazine-2,4-diyl)diimino]bis-9,10 anthracenedione; 2,2'-[1,2-ethanediyl bis-(oxy-2,1-phenylenazo)]-bis[N-(2,3- dihydro-2-oxo-1H-benzimodazol-5-yl)-3-oxo-butanamide; and N-[4-(amino carbonyl) phenyl]-4-[[1-[(2,3-dihydro-2-oxo-1H-benzimodazol-5-yl)amino]carbonyl-2-oxo- propyl]azo]benzaimide, or a mixture of these pigments. An amount of each pigment to be used is not particularly limited. However, if an amount is too small, lightproofness (resistance to transmission of ultraviolet rays) becomes insufficient and, if it is too large, coloring becomes deep and, accordingly, visual recognizability of contents in a container becomes difficult.
