<p>A compressible container (200) has a cap (100) configured to engage therewith. The cap (100) includes a first valve (150), preferably in the form of first and second disks (112,120), one above another, each disk having at least one hole (113,122) therethrough. The disks are rotatable with respect to one another The holes (113,122) of the first and second disks (112,120) align in a first position to create channel therethrough and misalign in the second position to close the channel. The cap (100) may also include a second valve (130) connected to the channel. The second valve (130) may comprise a ball (134) inside a conic section tube (132). The ball (134) is designed to float on the liquid (300) so that any liquid (300) attempting to exit the container cap (100) will be prevented from doing so as the second valve (130) will be closed when the liquid forces the ball (134) into engagement with the conic section tube (132).</p> |
