The present invention relates to a dispensing pump which mainly comprises a cap, a cylindrical pump body having a first elastic member therein, a ball valve fixed at a bottom of the cylindrical pump body, a needle valve fixed at a top end of the cylindrical pump body, and a pressing tube connected to an upper side of the needle valve and having a pressing head connected to an upper end thereof.

An e-liquid bottle includes a main body for receiving e-liquid therein, and an e-liquid injecting member mounted on a bottleneck of the main body. The e-liquid injecting member includes a sleeve, a chamber formed inside the sleeve for storing e-liquid therein, a single valve connected between the bottleneck and an e-liquid suction portion of the chamber for controlling the e-liquid flow to the chamber, a piston installed in an e-liquid feeding portion of the chamber, an e-liquid guiding pipe formed on the piston and extending into the sleeve, a base mounted on the sleeve to engage with the e-liquid pipe and driven by the piston move back and forth along the chamber to control the pressure in the chamber, an e-liquid feeding tube connected to an e-liquid outlet of the e-liquid guiding pipe. An interval is formed between the piston and the base so that the piston can move along the interval towards the chamber to separate the e-liquid guiding pipe from the base and connect an e-liquid inlet of the e-liquid guiding pipe with the chamber.

An assembly comprising, an attachment; and a container, the container including a main body and a tube section, the main body forming a storage space, the tube section having an opening that communicates with the storage space, the tube section having an outer circumference surface provided with a first engagement section, the first engagement section having a first surface facing a first direction that is a direction toward the storage space, the attachment including a ring-shaped section that is fittable with the tube section, the ring-shaped section having an inner circumference surface provided with a second engagement section, the second engagement section having a first surface facing a second direction that is a direction away from the storage space, the first engagement section and the second engagement section being engageable with each other when the first surface of the first engagement section abuts on the first surface of the second engagement section, drag force in the second direction being larger than drag force in the first direction, the drag force being force for the first engagement section or the second engagement section to go over each other.

In exemplary embodiments of the present invention, various novel dispensing devices can be provided. Such devices can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Novel sprayer/foamer heads can include buffers of various types. By using a buffer, a user need not continually be pumping the device in order for the device to be spraying or foaming. In exemplary embodiments of the present invention, such a buffer can be spring loaded, spring loaded combination, elastomeric or gas. In exemplary embodiments of the present invention, the buffer can be in line or adjacent to a piston chamber. If adjacent, it can be connected to the piston chamber with a one way valve, to provide for spray after a downstroke of the piston has been completed, or without, to allow spraying to cease once a user releases the trigger or other actuator. In exemplary embodiments of the present invention, such novel sprayers and foamers can be mounted upside down, in various Flairomop devices, used to clean floors or the like. When using a buffer, a piston chamber can be designed to deliver greater amount of liquid per unit time than can be possibly dispensed through the nozzle or nozzles. The fraction of liquid that cannot be sent through the nozzle(s), due to their inherent restriction, can thus be sent to the buffer for dispensing after the piston downstroke has been completed. A volume of the piston chamber, a volume of the buffer, a pressure response of the buffer, the throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.

A nozzle arrangement adapted for a pump dispenser, e.g. a manually-operated pump dispenser, that is activated by an actuation stroke of an actuator or a trigger handle to dispense a fluid from a container as a spray, e.g. an atomised spray, a foam, a gel, a paste or a liquid, wherein the nozzle arrangement is positioned downstream of, and in fluid communication with, a pump chamber of the dispenser and the nozzle arrangement comprises: an expansion chamber having an inlet and an outlet; and a movable plunger disposed within the expansion chamber, the movable plunger being arranged such that it can move, in use, in an upstream and downstream direction to vary the volume of the expansion chamber, wherein the plunger is biased by a resiliently deformable component such as a spring, the resiliently deformable component providing a biasing force in the downstream direction; wherein, in use, the actuation stroke causes the fluid to enter the expansion chamber at a faster rate than the fluid can be discharged from the expansion chamber via the outlet, whereby a pressure build-up within the expansion chamber pushes the plunger in the upstream direction against the biasing force provided by the resiliently deformable component such that fluid entering the expansion chamber is discharged via the outlet during the actuation stroke and after the actuation stroke, due to the biasing force provided by the resiliently deformable component causing the plunger to move in the downstream direction, thereby causing fluid to be discharged via the outlet.

A foam dispenser has a pump body and a sprung plunger (2). A one-piece moulded cylinder component (31) comprises a larger diameter portion (32) for an air cylinder and a smaller diameter portion (33) for a liquid cylinder. The plunger (2) carries respective pistons (22,21) movable in the air cylinder and liquid cylinder to pump air and liquid through valved outlets to a mixing chamber (8) in the plunger for foam production. The liquid cylinder has a discrete inlet piece (9) including an inlet valve. The liquid outlet valve is operated by a valve pin (25) connected to a valve pin retainer (39) which is formed integrally as a one-piece moulding with the cylinder component (31).

A push pump dispenser injects liquid within a cylinder portion from a nozzle portion by pushing down the finger putting portion located above a grip portion in a state where the grip portion has been grasped by a user. A finger abutting portion of the grip portion is located behind a power point of the finger putting portion.

A dispensing closure (10) for dispensing a flowable product (12) from a squeeze-type product container (14) includes a closure body (16) having an upper deck (32), an exit orifice (34), a flow conduit (36) providing a flow path to the exit orifice, and a skirt (40) configured to attach to the product container. A measuring reservoir (26) is received in engagement with a lower surface of the upper deck. The measuring reservoir is filled with a measured dose of flowable product through flow ports (54) when the container is inverted. A piston valve (28) is slidably movable within the measuring reservoir between an open position and a closed position. The piston valve is movable from the open position to the closed position to dispense the measured dose of product responsive to pressure within the container induced by squeezing.

To implement a complex math function, i.e. a math function with multiple input variables, a configurable computing array comprises at least an array of configurable computing elements. Each configurable computing element comprises at least a memory which stores a look-up table (LUT) for a math function with a single input variable.
