A waterproof emulsion pump with an external spring includes a pump body extending into a bottle body, a pump chamber is arranged in the pump body, a locking bottle cover is connected to the pump body, a pumping component is arranged in the pump chamber, and a locking cover is connected to the pump body; a one-way valve is arranged at a lower end of the pump chamber, an upper end of the pumping component is connected with a pressing head capable of driving the pumping component to operate, the pumping component includes an upper pump rod, a spring is arranged between the upper pump rod and the locking cover, a lower end of the upper pump rod is connected with a lower pump rod, a liquid inlet groove opening is formed in the lower pump rod.

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 body cylinder and providing an external collar through which the plunger stem operates. The body insert has a lock-down thread to lock down the plunger for shipping. The insert also has an undulating annular vent-control bead extending right round its cylindrical outer surface, engaging the cylinder wall with interference for either blocking or unblocking the vent opening, according to whether the vent-control bead lies above or below the interior vent opening, by rotation between the body cylinder and body insert. The rotation can be driven by rotation of the plunger head, which makes a catch engagement with the top of the body insert. Blocking the vent during shipping reduces leakage.

Provided is a cosmetic container having a retractable button including: a container body filled with contents; a pump part arranged on the upper portion of the container body in order to discharge the contents externally through a pumping action; and a button part arranged on the upper portion of the pump part to make the pumping action carried out by the user's pressing and releasing action, the button part having a discharge part to discharge the contents externally, wherein the button part has an inhalation space formed inside the button part, and the inhalation space is communicated with the discharge part, is increased or decreased in volume according to pressurization and release of the button part in order to inhale the contents remaining in the discharge part.

Disclosed are a pressure regulator for reciprocating pumps comprising an audible low pressure blow off and pumps comprising the pressure regulator. Also described is a pump comprising a larger diameter barrel with a higher volume for inflating an inflatable object at a lower pressure and a smaller diameter barrel with a lower volume for inflating an inflatable object at a higher pressure, wherein the pump is switchable to operate using either the larger diameter barrel or the smaller diameter barrel using a single lever attached to an end cap of the smaller diameter barrel.

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.

A fluid dispenser includes a ring nut to be screwed on a bottle neck and including a shoulder and a collar extending in elevation from the shoulder. It also includes a dispensing head including a central portion, a spout designed to dispense the fluid contained in the bottle and a protective skirt extending to contain the collar of the ring nut. The protective skirt extends close to a peripheral portion of the shoulder and, in a closed configuration of the dispenser, has a safety distance from the shoulder. The dispensing head includes a cylindrical crown shaped to form a toothed profile and located between the protective skirt and the central portion. The ring nut collar includes gripping elements with a longitudinal extension and the toothed profile engages the gripping elements when closed. The toothed profile and the gripping elements are shaped to allow reciprocal rotation of the dispensing head.

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 method is provided for the re-filling with product of a travel dispenser (10) which has two assemblies (12, 14) which are connected together mechanically for dispensing the product. A first assembly (12) includes a bottle (10) of the product, a venting passage which is able to be opened to connect the interior and the exterior of the bottle and a pump (22) mounted on the bottle which is able to assume an upper rest position in which the passage is closed and a lower position in which the passage is open. A second assembly (14) includes a product dispensing device (16). The method includes blocking of the pump (22) in the lower position, and disengagement of the two assemblies (12, 14) from one another in order to allow the bottle (10) to be re-filled with product through the open venting passage of the first assembly (12) in re-fill mode.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

A lotion pump includes a pump body with a pump chamber, the pump body is connected with a bottle-locking cap used for fixing the bottle body, and the pump chamber is internally provided with a pumping assembly capable of moving up and down in the pump chamber to pump lotion in the bottle body upwards; the lower end of the pump chamber with a one-way valve only for discharging the lotion in the bottle body upwards during the pumping assembly, the upper end of the pumping assembly is connected with a bent mouth for discharging the lotion, the bent mouth with a connecting ring, the upper end of the pump body with a locking part capable of being rotationally connected with the connecting ring, and an anti-slipping structure between the locking part and the connecting ring for preventing the bent mouth from being unscrewed and opened mistakenly.
