ABSTRACT:
A container cap having, for example, a cylindrical base that is threadedly securable to a container, for example, a plastic bottle, is disclosed. The base has a tubular portion that terminates in an open end to which is affixed a plug member by means of a number of laterally extending ribs. Such ribs support the plug member axially beyond the open end of the tubular portion and leave at least partially open the open end of the tubular portion. A sleeve is secured in surrounding relation to the tubular portion, the sleeve being displaceable axially along the tubular portion between two extreme positions. The sleeve terminates in an open end corresponding cross-sectionally in size and configuration to the plug member, the sleeve having an axial extent such that when it is in one of the extreme positions the open end thereof surrounds the plug member in substantially fluid-sealing relation. A sleeve-displacement device is provided for shifting the sleeve relative to the tubular member to the other of the extreme positions at which the open end of the sleeve is remote from the plug member and entirely open. The sleeve-displacement device is particularly actuable in a direction opposite the direction that the sleeve is displaced to its entirely open position remote from the plug.
