Abstract
A disinfection apparatus including a container; a cap having an article-retainer, a and a catalytic element-retainer means affixed thereto; and a catalytic element. The disinfection apparatus has particular utility in the disinfection of contact lenses with hydrogen peroxide solutions. Also disclosed are venting and sealing components, catalytic elements, molded article-retaining assemblies, and catalytic element formation methods.
Claims14
A disinfection device, comprising:
- (a) a container adapted to receive a disinfecting solution, said container having at least one end which includes a substantially circular periphery defining an opening which is adapted to receive a lens retaining means;
- (b) a cap adapted to be releasably affixed to said container at said open end;
- (c) an elongated member affixed to said cap, wherein said elongated member extends into said container when said cap is affixed to said container;
- (d) means for retaining articles to be disinfected, said article-retaining means being affixed to said elongated member, whereby said article-retaining means extends into said container when said cap is affixed to said container;
- (e) means for releasably sealing said container along the interior periphery of the substantially circular container, thereby providing a normally liquid-impermeable seal, wherein said sealing means is affixed to said elongated member interposed between said article-retaining means and said cap,
- whereby said sealing means is at least partially deformable, such that internal gas generated within said container will vent to a point outside said container, when the internal pressure reaches a predetermined pressure in excess of the external pressure, by at least partially deforming a portion of said sealing means, thereby forming a passageway between a point inside said container to a point outside said container;
- and
- (f) a catalytic element affixed to said elongated member, wherein said catalytic element is positioned inside said sealed container when said cap is affixed to said container.
5 more elements
An assembly for retaining ophthalmic lenses, sealing a container, and retaining a catalytic element, said assembly comprising:
- (a) a cap including a means for affixing said cap to a container to be used with said assembly;
- (b) an elongated support member affixed to said cap;
- (c) means for sealing a container, said sealing means being affixed to said elongated support member, said means being capable of forming a substantially liquid impermeable, gas permeable chamber with a container along an interior periphery of the container;
- (d) means for retaining contact lenses affixed to said elongated support member;
- (e) a means for retaining a catalytic element, said catalytic element-retaining means being affixed to said elongated support member;
- and
- (f) a catalytic element retained within said catalytic element-retaining means.
