ABSTRACT:
A squeeze bottle dispenser includes a squeezable container, a cap with a tubular nipple defining a central passage, and an extensible dispensing tube extending from the interior of the container through the passage, the tube having an outer end terminating in a dispensing orifice. The tube is movable between retracted and extended positions, and it is spring-biased toward its extended position when it is in its retracted position. A removable closure is sealingly engageable with both the outer end of the tube and the nipple, so as to seal both the passage and the dispensing orifice when the tube is in its retracted position, and the dispensing orifice separately when the tube is in its extended position. When the tube is in its retracted position, its inner end is pushed against an internal surface of the container, thereby causing it to bow. It is retained in this bowed configuration by the simultaneous engagement of the closure with both the outer end of the tube and the nipple. The bowing of the resilient tube causes it to store potential energy much as a spring, so that, when the closure is disengaged from the nipple, the tube straightens out, causing its outer end to be pushed further out of the passage. The closure, still engaged with the outer end of the tube, is used to pull the tube to its extended position.
