A pump assembly for a pump assembly for a dispenser container comprises a cap having a housing and a spout and a collar having a stop member. A sleeve is at least partially positioned within the collar and comprises a sleeve chamber. A plurality of resilient members are housed within the sleeve chamber. Compression of the cap causes compression of the plurality of resilient members and engagement of the cap with the stop member of the collar. The cap, the collar, the sleeve, the at least one valve, and the plurality of resilient members are comprised of a same type of recyclable material.

The present invention concerns a dispensing device (100) for dispensing a liquid or fluid held in a container (C). The device (100) comprises: an engagement portion (101) for mutually engaging the device (100) and the container; drawing and dispensing means (102) suited to draw the fluid or liquid from the container (C) and then dispense it; a hollow operating cap (103) for operating the drawing and dispensing means (102); a dispensing nozzle or spout (104) provided with a dispensing duct (105) fixed to the operating cap (103). The dispensing nozzle or spout (104) can be switched through a rotary movement between a first dispensing position and a second non-dispensing position. The operating cap (103) and the dispensing nozzle or spout (104) are shaped in such a way as to respectively define a first stop surface (107) and a second stop surface (108); in the dispensing position the first and the second stop surfaces (107, 108) are arranged against each other.

An actuator for a spray can. The actuator includes a housing for attachment to an aerosol can covering a stem valve. A finger operating button structure is engaged with the housing for engaging the stem valve. A rotary two-way diverter valve is supported within the housing and rotatably engaged with the finger operating button structure. In a spray position/straw down, the two-way diverter valve directs spray through a first direct spray nozzle. In a second straw position/straw up, to make use of an adjustable straw, the diverter valve is rotated to engage a straw spray passage of the diverter valve in fluid communication with an adjustable rotary spray tip and engaged straw. By rotating the adjustable rotary spray tip to an aligned position, the tip substantially blocks the straw spray passage to provide a drip mode, where drops of fluid exit the straw. A flexible tip may optionally be provided on the straw to enable bending and retention of the flexible tip to a desired position.

A hand pump design that utilizes an actuator with a folding nozzle suitable for use in e-commerce is presented. The folding nozzle equipped pump actuator forms part of a hand pump assembly which incorporates a pump body assembly comprising upper and lower pump bodies and a sliding collar which controls the inlet of fluid to be dispensed into fluid passages in the pump assembly and subsequently into the pump actuator. The hand pump further includes upper and lower check balls to prevent back flowing of the fluid to be dispensed into the dispenser bottle.

Dispensing systems (100) having wands (110) for distributing a spray away from a user include moveable wands (110), wands for locking actuation of the dispensing system (210), wands and dispensers providing gravity fed dispensing solutions (410) for battery-operated devices (500) and improved dispensers.

A pump dispenser having a bottle with a neck and a pump assembly. The pump assembly includes an actuator, a closure connected to the actuator and coupled to the neck of the bottle, a dip tube, and a dual chamber pump. The dual chamber pump includes a piston assembly, a sealing cap, and a housing, which includes a pump chamber, a storage chamber having a cavity, and a core. The sealing cap is rigidly connected to the core and closes the storage chamber at a lower portion such that the substance to be released remains stored in the storage chamber cavity. When the actuator is pushed down for a first time by a user, a piston assembly moves to push down a connecting stem, which pushes down the sealing cap to open the storage chamber for releasing the substance contained in the storage chamber from the bottle.

A dispensing device dispenses a liquid held in a container. The device includes an engagement portion for the mutual engagement of the device and the container. Drawing and dispensing means draws the liquid from the container to dispense it. A main operating body operates the drawing and dispensing means through pressure exerted along a pressing direction. The main operating body moves with respect to the engagement portion, when subjected to pressure, between a rest position and an activating position. A dispensing nozzle is fixed to the main operating body and provided with a dispensing duct suited to dispense the liquid. The dispensing nozzle is switched from the main operating body, through a rotary movement, between a dispensing position and a non-dispensing position. Constraining means prevents the movement of the main operating body along the pressing direction when the dispensing nozzle is in the non-dispensing position.

The invention relates to a system having a dosing dispenser for dispensing pasty or viscous material with a housing, a cartridge displaceably accommodated therein and a walking piston accommodated in the cartridge that forms a unit ready for assembly with a shutter button to be arranged at a cartridge end.
