Abstract
There is described a container (1) for the accommodation of a contact lens during treatment process such as extraction and/or rinsing and/or coating processes, which comprises an elongated tubular body (2) having a sidewall (3) and at one longitudinal end thereof a bottom (4) which protrudes convexly towards the outside of the tubular body (2). At the opposite longitudinal end the tubular body (2) has an access opening (5). The bottom (4) is provided with a number of apertures (41, 42) which enable a free flow of a liquid into and out of the tubular body (2). A retaining element (6) is located inside the tubular body (2), which allows access of a transfer means into the tubular body (2) towards the bottom (4) thereof for insertion and removal of a contact lens, and enables a free rising of the liquid inside the tubular body (2), but prohibits the contact lens from being washed out of the tubular body (2).
