A pump dispenser is described for dispensing a product through a pumping mechanism that draws product from a storage container upwards through a dip tube, across a check valve, into a collecting chamber from which it is dispensed through a one-way monitoring valve and exits a nozzle. Flow is initiated by compression of a domed elastomeric wall covering the collecting chamber. A vent system of conduits including a conical ring valve brings air into the container to equalize pressure upon release of compression against the elastomeric wall. The one-way monitoring valve, downstream from the collecting chamber, may be formed as a duckbill valve of elastomeric rubber having an exit slit at the dispensing end. This slit, normally closed, will open upon pressure from a product flow. Excellent control of dispensing amounts is achieved through the pumping mechanism.

Pump dispenser

A dispensing package is provided with a container and a cap. The cap includes a mechanism to fittingly engage across an open end of the container, a top portion defined by a deck, a skirt wall surrounding the deck, at least one dispensing orifice formed in the deck, a locking aperture with a wide and a narrow area preferably in a T-shape, a lid hingedly attached to the deck, a flexible post projecting downwardly from the lid, and a release mechanism along the skirt. The flexible post has an enlarged section at an end thereof which can lockingly engage underneath landings that define wide and narrow areas of the locking aperture. A flexible area along the skirt can be pushed inward against the enlarged section of the post to dislodge same from underneath the landings thereby opening the lid.

Child-resistant closure

A wide roll on product dispenser is provided with a valve mechanism which is operated by movement of the roller using toward and away from the fluid reservoir. In a preferred arrangement the housing mechanism is moved by applying and removing a roller overcover.
