ISOLATION OF PRODUCT AND PROPELLANT IN AVARIOUS DISPENSING DEVICES AND PLATFORMS (FLAIRFRESH).

摘要

In exemplary embodiments of the present invention platforms from which various dispensing devices, both manually operated as well as "touch-less" (motion sensor based) are presented. Such exemplary devices incorporate two main components: (i) the "bag within a bag" Flair® technology, and (ii) a OnePak type dispensing head (with a normally closed outlet valve). Such platforms can be, for example, overpressure based or underpressure based, can have various application based features, and can interface with various exemplary Flair type bottles. Exemplary embodiments described herein relate to dispensing systems where (i) the fluid or other dispensate to be dispensed, and (ii) the propellant used to dispense it, whether said propellant is a fluid, a gas, air at atmospheric pressure, or other, are completely separated in separate circuits, controlled separately, and only optionally mixed at the final dispensing time, if desired, at a point downstream of the normally closed outlet valve. Additionally, in such devices the propellant can be used for other ancillary functions, such as, for example, cleaning a spout or output channel, making foam or spray, controlling valves, pistons, pumps, making noise, and the like. Certain of such exemplary systems utilize a unique bottle in the dispensing appliance which (i) cannot be replaced by a competitor's, or other third party's bottle which also (ii) cannot be refilled by a consumer.
