Abstract
A valve is described having a ridge extending along a flat surface having holes therein and a base of elastic material compressed against the ridge and flat surface so as to define a channel of small cross-section communicating between the openings. A tab is connected to the side of the base of elastic material that is remote from the ridge and the flat surface so that a pull on the tab pulls the base away from the flat surface and enlarges the cross-section of the channel.
