A dispenser pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the outer body and providing an external collar through which the plunger stem operates. The body insert has lock-down threads to lock down the plunger for shipping. The insert also has formations for blocking or unblocking the vent opening by rotation between the outer body and body insert, driven by rotation of the plunger head which makes a catch engagement with the top of the body insert. This plunger head rotation is the locking or unlocking action for the plunger lock-down. Blocking the vent during shipping reduces leakage.

A spray device includes a bottle portion, a sleeve, and an engine. The engine includes a spring that when compressed pressurizes a chamber containing a dispensable amount of fluid from the bottle portion. The sleeve and the engine are configured to be torquable onto the bottle without compressing the spring. Rotation of the sleeve relative to the bottle by a user pressurizes a chamber containing fluid from the bottle. Auditory and/or tactile feedback is provided to the user during rotation of the sleeve thereby allowing the user to select an amount of the fluid to be dispensed. The engine includes a main spring that when compressed pressurizes a chamber containing a dispensable amount of fluid from the bottle. The spring is enclosed between a cup and a cap, which have been fused together.

A manually operated pump including: an inlet one-way valve; a pump chamber downstream of and in fluid communication with the inlet one-way valve; a piston interior to the pump chamber and slideably engaged with the pump chamber; an actuator engaged with the piston or the pump chamber; a block thermoplastic elastomeric spring engaged with the actuator to move the actuator as the block thermoplastic elastomeric spring relaxes; and an optional outlet one-way valve downstream of and in fluid communication with the pump chamber.

Disclosed herein are embodiments of a manually operated liquid dispenser. In any embodiments disclosed herein, the dispenser can include a housing with a volume of space therein, the volume of space having a first end and a second end, a pump sleeve extending into the space of the housing and nearly to a bottom, inside surface of the space, a pump head, a push rod coupled with the pump head and configured to be axially movable within an axial opening extending through the pump sleeve, a passageway extending through at least the pump head and the push rod, the passageway being in fluid communication with the axial opening extending through the pump sleeve and with the volume of space within the housing, and a first valve configured to control a passage of a liquid substance within the volume of space in the housing through a passageway.

A pump assembly for a pump dispenser, the pump assembly comprises a cap having a housing and a spout, a collar, a sleeve, and a dip tube. The sleeve is at least partially positioned within the collar and comprises a coupling member. The coupling member comprises a shoulder, a coupling joint, and a coupling member channel extending from the shoulder to the coupling joint. The dip tube has a first end and an opposing second end, and defines a dip tube channel extending from the first end to the second end. The first end of the dip tube is configured to pivotally couple to the coupling joint and fluidly connect the dip tube channel and the coupling member channel. The dip tube channel comprises a first diameter at the first end and second diameter at the second end that is different than the first diameter.

Disclosed is a refillable cosmetic container including a container body provided with a main body of which an one side is opened; a refillable container part detachably coupled to the main body and in which a cosmetic liquid is stored; a support part coupled to the other side of the main body; and a pumping driving part coupled to the support part to discharge the cosmetic liquid stored in the refillable container part to the outside of the refillable container part, wherein the refillable container part includes a refillable container body detachably coupled to the main body and a shifter part detachably coupled to the refillable container body and penetrated with a tube member of the pumping driving part, and a film is provided between the refillable container body and the main body to be easily separated when the refillable container body is separated from the main body.

A handheld shower includes a shower body and a liquid storage tank. The shower body has an inlet channel and an outlet portion, and the inlet channel communicates with the outlet portion. The liquid storage tank has a receiving space and a liquid outlet, and the receiving space is adapted to receive a cleaning solution. The liquid outlet communicates with the receiving space and is adapted to output the liquid solution inside the receiving space. The liquid storage tank is detachably engaged with the shower body, and the handheld shower is light and easy to carry. Thereby, users no need to carry many bottles of cleaning solution when traveling or on business trips, and have their own handheld shower when they are going out, enhancing the convenience of the journey and the comfort of bathing outside.

A hand pump fabricated entirely from plastic components for dispensing liquids, is provided. The hand pump includes an actuator, a closure, a housing having a lower check valve, and a piston having an integrated upper check valve in the form of an inverted cone suspended within a cylinder. An elastic, dome shaped, plastic return spring is utilized to return the actuator to its rest position after actuation. Used pumps do not require disassembly to be recycled.

The present disclosure provides a toilet spray apparatus which operates automatically, removing the need for a user to take any actions to reduce or eliminate toilet odours, and which requires no batteries to operate, instead taking advantage of the pressure resulting from a user sitting on a toilet seat. In response to a user sitting, the apparatus will emit a vaporised spray of fluid into a toilet bowl forming a protective layer that prevents unpleasant odours from rising. The apparatus comprises a reservoir body, a spring-operated pump mechanism, an extended outlet for hooking over a toilet bowl rim, and a housing.

A lotion pump includes a movable portion and a stationary portion. A shifting mechanism is formed on the movable portion and the stationary portion, which shifts the elastic restoring mechanism of the lotion pump between a standby state and a non-standby state as the movable portion rotates or moves up and down. The structure of the lotion pump can prevent the spring from yielding due to compressed for a long time, while can also realize a form of locking at lower position.
