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).
