The present invention concerns a device (1) for dispensing a fluid (L), suited to be coupled with a container (C) holding said fluid (L). The device (1) comprises a collapsible chamber (6) suited to draw, contain and dispense an amount of said fluid (L) and at least partially delimited by a deformable membrane (10) suited to be squeezed to dispense at least one portion of said amount from the collapsible chamber (6). The device (1) comprises locking means (50, 52, 56) suited to maintain the deformable membrane (10) in a fixed squeezed position and release means (80, 84a, 84b, 86a, 86b) suited to release the deformable membrane (10) from the fixed squeezed position.

Disclosed is a heterogeneous contents mixing container with improved productivity and sealing ability. The heterogeneous contents mixing container includes a container body for containing a second content; a first content receiving member formed in the container body to contain a first content and including an upper separation cap and a lower fixing cap; a shoulder rotatably coupled to the container body; a lift guide member fixed to the container body and formed with a spiral groove; a lift member moving up by a rotation of the shoulder and formed with a lift protrusion; a pump housing moving up with the lift member; a discharge pump moving up with the pump housing to pump the first and second contents mixed with each other; and a push button coupled to the discharge pump to be movable up or down and formed with a discharge outlet.

A pump dispenser has a pump body and a reciprocable plunger with a lock-down mechanism, comprising internal or external lock formations of the plunger and body, such as thread formations, by which the plunger can be locked down for shipping and released subsequently by a rotational release movement. To supplement security for demanding shipping conditions the dispenser also has a supplementary catch mechanism in which respective catch formations of the plunger and body engage selectively in the locked-down position to inhibit the rotational release movement. The catch formations may have circumferentially-directed surfaces which engage between the underside of a plunger head having a shroud and a nozzle and the top of the body beneath the plunger head. They can be released by resilient deformation of one or more of the catch formations.

A device for distributing a liquid. The device includes a bottle including a reservoir designed to store liquid, and a distribution element, and a concealment assembly. The distribution element allows the liquid to be distributed from the inside to the outside of the reservoir. The concealment assembly includes a base and a concealment ring that is movable along a main displacement axis from a first, operating position, to a second, locking position. The displacement of the concealment ring occurs through a helical movement of the concealment ring relative to the base in relation to the main displacement axis. As well, the displacement of the concealment ring from the operating position to the locking position allows at least part of the distribution element to be concealed. Finally, the concealment element further includes a ballast rigidly connected to the concealment ring.

An apparatus for pumping a selected sterilizing fluid by a user comprising: a fluid container, a pump assembly having a fluid delivery tube, the fluid delivery tube being manually drivable by the user in a downstream direction starting from a stationary start position and adapted to pump fluid upstream through an upstream end of the fluid delivery tube that is configured to receive and engage a complementary surface of an external device, the fluid delivery tube being drivable downstream from the start position by manually engaging the complementary surface of the external device against the upstream facing surface of the enlarged head and manually driving the external device in the downstream direction.

A fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

A trigger-type liquid ejector includes: an ejector main body; and nozzle member provided with an ejection hole. The ejector main body includes: a vertical supply pipe for sucking-up liquid; an ejection barrel communicating with the inside of the vertical supply pipe; and a trigger mechanism including a trigger, the trigger being arranged to be movable rearward in state of receiving forward force, and the trigger mechanism being lead liquid from the vertical supply pipe into the ejection barrel in accordance with rearward movement of the trigger and to eject the liquid from the ejection barrel. The nozzle member is provided with: a cylinder communicating with the inside of the ejection barrel through a supply hole; a plunger accommodated in the cylinder to be movable rearward in a state of receiving forward force; and a communication hole allowing the inside of the cylinder and ejection hole to communicate with each other.

A discharge pump (2) includes a stationary suction part (A) which includes a cylinder (A1) having a first check valve (V1) at a lower part thereof, and a mounting member (A3) to be mounted on a neck part of a container body, and an actuating member (B) which includes a discharge head (B4), a stem (B2), a piston guide (B1), and an annular piston (B3), a second check valve (V2) being formed between a lower end part of the annular piston and a lower part of the piston guide, and in a fitting part between the stem and the piston guide, an engaging unit (E) which is configured to restrict the stem and the piston guide from idling each other when screwing of the actuating member to the stationary suction part is released and the actuating member is raised from the stationary suction part is provided.

The invention discloses a waterproof emulsion pump with an external spring, which 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 piston is sleeved on an outer side of the lower pump rod, a pushing part is arranged on the upper pump rod, and a protruding part capable of contacting with a lower end of the piston to push the piston to move upwardly is arranged on the lower pump rod; and a waterproof structure is arranged between the upper pump rod and the locking cover.
