The present invention is directed toward molded plastic re-sealable closures ( 1, 31 ) for use with a fluent dispensing container ( 2 ). The closures ( 1, 31 ) each have a rupturing member ( 12 ) and a cover ( 19 ) on whose initial opening causes the rupturing member to tear a tearable sealing to form a generally rectangular fluent exit aperture ( 4 ), and secures the torn away material remote from the fluent exit aperture to prevent it from blocking same during subsequent re-openings and re-sealings. The present invention is also directed to screw cap assemblies ( 41, 61 ) similar to the closures ( 1,31 ) but each having an axially displaceable puncturing member and a cap on whose initial unscrewing causes the puncturing member to puncture a tearable sealing to form a generally circular fluent exit aperture. The present invention is further directed to toggle cap assemblies ( 71, 81 ) for use with a hand squeezable plastic bottle, the toggle cap assemblies each including a latchable arrangement disposable from a sealing position for preventing the dispensing of a bottle's contents to a flow communication position for enabling the dispensing of a bottle's contents on squeezing the bottle, and vice versa on applying a force against an exposed surface of the latchable arrangement in the direction of the bottle's interior. The present invention is still further directed to a collapsible plastic bottle ( 91 ), and a dual container dispenser ( 101 ). |
