Abstract:
A collapsible container for dispensing viscous materials has a bottle section with exterior screw threads and a cap element with nozzle aperture and internal, mating yet greater in density screw threads so that relative turning of the bottle section with respect to the cap section causes dispensing of material and collapsing of the bottle section into the cap element. The exterior screw threads are provided with uniformly spaced surface discontinuities. The cap element is provided with a resilient, inwardly directed tab which glides over the exterior edge of the screw threads of the bottle section as the bottle section is rotated with respect to the cap element until the tab aligns with a discontinuity thereof which causes an audible or tactile click to be sensed for ensuring uniformity and ease of exact dosing.
Abstract:
A dispenser (10) for viscous liquids in which a hollow cylindrical body (12) is provided with stationary walls (44, 46). A rotatable member (22) with vanes (24, 26) is situated within the body (12) so that rotation of the vanes (24, 26) will cause the liquids contained within the body (12) to be squeezed out through a nozzle (14) in one end of the main body (12). The other end of the main body is provided with a rotatable cap (32) to turn the vanes (24, 26) within the body (12).

Abstract:
A fluid dispensing system, fluid reservoir, refill container for refilling the fluid reservoir, and method of refilling the fluid reservoir are provided. The fluid dispensing system includes a refill connection port or nozzle to which a refill container is connected when refilling the fluid reservoir. The fluid reservoir includes a piston head and an actuator for moving the piston head in a first direction and in a second direction. When the piston head is moved in the first direction, the fluid within the fluid reservoir is pressurized, causing the fluid to be dispensed through an outlet of the fluid reservoir. When the piston head is moved in the second direction, a vacuum is created within the fluid reservoir that draws fluid, from the refill container, into the fluid reservoir. The fluid dispensing system includes a valve to enable multiple refill containers to be coupled to the nozzle and/or the refill connection port.
Abstract:
A delivering device (1) is described, in particular for pasty or creamy products preferably for domestic use, comprising at least one delivery duct (3) which puts in fluid communication at least one internal volume (5) of at least one container (7), the internal volume (5) containing therein at least one product, and at least one delivery nozzle (9) for exiting the product by interposing pumping means (11) actuated by at least one actuating motor (13) to transfer amounts of the product from the internal volume (5) to the delivery nozzle (5) through the delivery duct (3), and control means (14) actuated by a user and operatively cooperating with the actuating motor (13) to allow or inhibit at will an operation of the actuating motor (13) and perform or stop a delivery of the product through the delivery nozzle (9).
