A system for releasing a contained volume of gas. The system has a base with a pressure-release vent positioned within a flex region and a seal to disengagably seal the pressure-release vent. The seal has a gas vent path that extends from the pressure-release vent. The contained volume of gas passes through the gas vent path to apply force against the flex region and disengage the seal from the pressure-release vent, allowing the gas to exit through the pressure-release vent.

A method of removing a liquid from a container (1) for accommodating an ophthalmic contact lens, in particular a soft contact lens, during transporting the container (1) from a liquid bath (13) to a subsequent processing station (14), the method including the steps of: transporting the container (1) from the liquid bath to the subsequent processing station, generating suction (20), and applying the suction (20) to a bottom (11) of the container (1) during the step of transporting the container (1) from the liquid bath to the subsequent processing station, thereby removing the liquid from the container (1).

A disinfection system of a contact lens comprising immersing the contact lens in a disinfecting solution containing hydrogen peroxide in a concentration of 1 to 10% and neutralizing the hydrogen peroxide in the disinfecting solution through contact with a metal catalyst, where the disinfecting solution contains an organic carboxylic acid or a salt of the organic carboxylic acid, the organic carboxylic acid having a structure in which a hydroxyl group and a carboxyl group are bonded to one carbon atom; the disinfecting solution is adjusted to have a pH of 6 to 8; and the disinfecting solution after the neutralization is adjusted to have an osmotic pressure of 250 to 350 mOsm.

An ocular device case with a new structure that can solve unexpected problems in the related art, for example, adverse effects on user's eyes by splashes of treatment liquid upon pouring the treatment liquid into the device case from a separate refill container. In a device case including: a case body accommodating treatment liquid with ocular devices such as a contact lens; and a lid, a container receiving portion is provided such that a spout of a refill container is brought into contact with the refill receiving portion so as to allow the treatment liquid to flow into the device case.

The present invention relates to a lens care solution having 0.001 to about 5 weight percent of a low molecular weight amine of the general formula:

##STR00001##

where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are H or low molecular weight radicals, and R.sub.5 is a low molecular weight radical, or salt thereof; an effective amount of a tonicity agent; and the balance water.

A method of removing a liquid from a container (1) for accommodating an ophthalmic contact lens, in particular a soft contact lens, during transporting the container (1) from a liquid bath (13) to a subsequent processing station (14), the method including the steps of: transporting the container (1) from the liquid bath to the subsequent processing station, generating suction (20), and applying the suction (20) to a bottom (11) of the container (1) during the step of transporting the container (1) from the liquid bath to the subsequent processing station, thereby removing the liquid from the container (1).

A lens aid, lens aid system, powered light source, and cleaning and storage compartment for the lens aid system that uses a lens cup of soft pliable material providing an improved visual method including a hands-free or one hand method for the insertion of a contact lens and more preferably a scleral lens into the eye.

A one way plug and stem check-valve is disclosed. The one way plug and stem check-valve includes a plug that has a plug base of a smaller size than a plug top wherein the plug base and the plug top are about parallel, the plug having a sidewall connecting the plug top and the plug base together with a central axis connecting the plug base and the plug top at their respective centers, a leg wherein two or more of said legs are flexibly coupled to the plug base at an angle of about 1 degree to 45 degrees diverging away from the central axis, wherein the two or more legs are distributed about the radius of the plug base, a housing that encapsulates the plug with openings at the plug top and the plug base with similar geometry to that of the sidewall of the plug wherein the sidewall of the plug creates a fluid seal with an inside wall of the housing while in a static position, the housing allows displacement of the plug and legs along the central axis in the direction of the top of the plug wherein the said legs absorb energy as they are displaced inward toward the central axis of the plug by the housing, this absorbed energy is expelled by the legs as the legs and the plug return to their static position.

A disinfection system of a contact lens comprising immersing the contact lens in a disinfecting solution containing hydrogen peroxide in a concentration of 1 to 10% and neutralizing the hydrogen peroxide in the disinfecting solution through contact with a metal catalyst, where the disinfecting solution contains an organic carboxylic acid or a salt of the organic carboxylic acid, the organic carboxylic acid having a structure in which a hydroxyl group and a carboxyl group are bonded to one carbon atom; the disinfecting solution is adjusted to have a pH of 6 to 8; and the disinfecting solution after the neutralization is adjusted to have an osmotic pressure of 250 to 350 mOsm.

A method of sterilizing a preform includes steps of: sterilizing bacteria adhering to a preform (1) made of resin by gasifying a sterilizer, discharging a sterilized gas (G) from a nozzle (6) toward a preform (1), now traveling, so as to adhere to the preform (1); activating the sterilizer adhering to the preform (1) by blasting hot air (P) to the preform; and sterilizing bacteria adhering to the preform, and removing the sterilizer adhering to the preform (1), wherein the above steps are performed sequentially in order. According to the above-mentioned steps, the sterilizer does not enter a blow-molding machine.
