Document Type and Number:
Japanese Patent JP4071195
Kind Code:
B2
Abstract:
A contact lens container ( 1 ) includes a container ( 2 ) for receiving a cleaning and/or disinfecting liquid, as well as a cap ( 3 ), which can be screwed onto the container ( 2 ) by a thread ( 20,30 ). In the cap ( 3 ) a sealing washer ( 4 ) made of a water-tight and gas-tight material is provided, which is arranged on the inside of the cap ( 3 ) on the bottom ( 33 ) of the cap and extends to the side wall ( 32 ) of the cap ( 3 ), so that when the cap ( 3 ) is screwed on to the container ( 2 ), the sealing washer ( 4 ) is enclosed between the container edge ( 23 ) and the bottom ( 33 ) of the cap and the inside of the container has a water-tight seal. The cap ( 3 ) in the area in which the sealing washer ( 4 ) is enclosed between the container edge ( 23 ) and the bottom ( 33 ) of the cap is designed such that a cavity ( 34 ) is formed between the sealing washer ( 4 ) and the bottom ( 33 ) of the cap, so that, when there is excess pressure in the container ( 2 ), the sealing washer ( 4 ) is deformed into this cavity ( 34 ) and gas can escape from the inside of the container through the thread ( 20,30 ) out of the container ( 2 ). The sealing washer ( 4 ) is equipped with a sealing lip ( 42 ) at its border with the side wall ( 32 ) of the cap ( 3 ), the lip being designed such that, when the sealing washer ( 4 ) is deformed into the cavity ( 34 ), a water-tight seal is ensured with the side wall ( 32 ) of the cap ( 3 ).
