Abstract

An apparatus for storing and cleaning an element is disclosed. The apparatus includes a fluid containing receptacle having an open top and a cap having at least one opening therethrough for removably closing off the open top of the receptacle. The apparatus further includes an element retaining housing removably disposed internally of said receptacle. The housing has at least one opening therethrough fluidly communicating the interior of the housing with the exterior thereof. The apparatus also includes a resilient gasket mounted in the receptacle adjacent the opening in the cap. The gasket has normally closed valving means therein adapted to open upon a predetermined incrase in pressure within said receptacle to release the pressure through said valving means and out of said opening in said cap.

Claims11

Dependent claims

A vented contact lens storage and cleaning container comprising:

a container having a side wall, a bottom wall and an open top;
a cap removably attached to said container and closing off said opening in said container, said cap having an upper surface and a lower surface, said cap having a recess in said lower surface and a vent hole located within said recess and extending through said cap;
a gas and liquid impermeable gasket adjacent said vent hole in said cap including at least one "H"-shaped perforation extending therethrough which acts as a one way valve, said "H"-shaped perforation forming a pair of adjacent flaps which are normally closed and in abutting relationship forming a fluid-tight seal, said flaps being deflectable at sufficiently high pressure levels to move away from their normal closed position to permit gas to vent through said perforation and out of said vent hole and said caps thereby providing two hinged venting flaps allowing fast evacuation of gasses generated within said container;
and
basket means removably mounted in the interior of said container for removably containing contact lenses and allowing liquid to freely flow over the contact lenses.

Apparatus for storing and disinfecting contact lenses comprising:

a fluid containing vial having a sidewall, a bottom wall and an open top;
a cap capable of engaging said vial including a top side and a bottom side, said bottom side having a recessed groove and at least one vent hole within said recessed groove;
a basket attached to said bottom side of said cap for retaining at least one contact lens therein, said basket having at least one opening therethrough fluidly communicating the interior of said basket with the exterior thereof;
and
a vapor and liquid impermeable resilient gasket mounted adjacent said recessed groove, said gasket having at least one slit therethrough, said slot being "H"-shaped and forming a pair of adjacent flaps which are normally closed and in abutting relationship forming a fluid-tight seal, said flaps being deflectable at sufficiently high pressure levels to move away from their normal closed position to permit gas to vent through said slot and out of said vent hole and said cap thereby providing two hinged venting flaps allowing fast evacuation of gases generated within said vial.
