The present invention relates to fluid dispensing devices for use in dispensing different liquids (e.g., bleach and bleach activator) from a bottle having first and second compartments. To minimize the presence of mixed composition residually present within the fluid dispensing device, it may be helpful to delay mixing. Separate dip tubes may be provided to pull liquid from the separate compartments, each with its own separate pump. Each pump may deliver the separate compositions to a spray nozzle of the device through separate delivery tubes (e.g., from the pumps to the nozzle). In other embodiments, a single delivery tube, and/or a single pump may be provided, e.g., where the volume of mixed composition that may be present in such pump and/or delivery tube may be sufficiently small so as to still provide overall desired efficacy characteristics. Dual delivery tube configurations may eliminate any need to prime the device by spraying out old, residual mixed composition.

A head (10) of a trigger dispensing device (1) for liquids includes a pre-compression valve (104) disposed in the upper region of the head. The valve (104) has an obturator wall (106) that cooperates with a mouth wall (102) to prevent the passage of liquid. The mouth wall (102) includes a sealing section (102a) with which the obturator wall (106) is sealingly engaged to slide during a pre-compression step of the liquid.

The present invention discloses a configurable computing array comprising three-dimensional writable memory (3D-W). It is a monolithic integrated circuit comprising an array of configurable computing elements, an array of configurable logic elements and an array of configurable interconnects. Each configurable computing element comprises at least a 3D-W array, which stores at least a portion of a look-up table (LUT) for a math function.

A manually operated pump (1) for dispensing a fluid substance in which the movable element (16) of the delivery valve has an at least partially conical surface adapted to be coupled with a corresponding surface of a seat of the delivery valve, in a manner so as to be fit therein due to the action of the spring (10) that loads the movable element (16).

A system for dispensing a personal care fluid, such as a hand soap or the like. The system includes a dispenser and a refill cartridge. The dispenser includes a dispenser body having a refill cavity and a dispenser lid configured to be coupled to the dispenser body. There may be a pump sub-system mounted to the dispenser lid, or alternatively the personal care fluid may be dispensed by squeezing the dispenser and refill cartridge. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The personal care fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

An outlet valve for a dispensing nozzle comprising a first valve component constructed and arranged to be received by the dispensing nozzle and a second valve component constructed and arranged to cooperate with the first valve component. The first valve component and the second valve component define a normally-closed flow interface.

Flairosol dispensing devices are presented. They utilize a combination of Flair technology, precompression valves and aerosol like pressurization of the dispensed liquid. An exemplary device has a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring, a piston and a piston chamber which draws liquid from a container, and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve, which serve to prevent backflow. A dome valve can be provided near the outlet channel at the top of the dispensing head, such that once its pressure is exceeded by the liquid, it opens and allows for a spray. Alternatively, in an activated embodiment, the dome valve is locked unless opened by a user.

A squeeze bottle, useful for atomizing liquids such as perfumes, medications, insecticides, or the like, by manually squeezing the bottle while orienting the bottle to direct the resulting atomized spray for a desired application. The squeeze bottle utilizes ambient air and contains an inner, compliant pouch for storing a liquid. The pouch is configured so that it deforms by the hydrostatic air pressure generated within the bottle during a squeezing action. This deformation assists in transferring liquid from the pouch into the bottle's spray nozzle where the liquid is atomized in a swirl airflow and dispersed by the expelled ambient air.

A suck-back valve selectively actuatable for dispensing liquid in its open condition from an associated liquid storage container, and for avoiding continued presence of excess dispensed liquid about the exit orifice in the closed condition of the valve, is formed at least in part of a spring member and a pin. The spring member includes a distal web that defines a valve seat and a dispensed liquid exit orifice, a proximal web, and a plurality of flexibly elastic bands helically connecting the distal and proximal webs. The pin includes an elongated shaft having a proximal end secured to the proximal web and carrying a substantially hollow frustoconical cone at its distal end. The cone has an outer valving surface for releasable abutment with the valve seat and the shaft has a bore of predetermined cross-sectional extent defined longitudinally along and within the shaft to create a continuous fluid passageway through and along the pin. Dispensed liquid remaining proximate the exit orifice is sucked back into the liquid container through the shaft bore as the valve returns from its open to its closed condition under the return urgency of the elastic bands.
