An upper end of the primary column (2) is provided with a locking flanging (21) which is turned outwards and then turned downwards to stretch in order to be sleeved on the outer side of the locking opening (92). An inner side of the locking flanging (21) is provided with an inner thread (22) in threaded fit with the outer thread (93), such that a pump core composed of the primary column (2), the secondary column (3), the piston (4), the pump chamber (5), the spring (6), a glass bead (7) and the lock cover (9) can be stored and transported independently, thereby matching different pressing heads (1) and bottle locking covers (8) according to requirements, such that the use thereof is flexible.

The invention relates to a cosmetic container. According to one aspect of the invention, there is provided a cosmetic container, including: a storing unit providing a first storing space which can store fluid; a discharging unit which discharges the fluid stored in the storing unit to the outside; and a fluid supporting unit which can support from a lower direction fluid which has been discharged to the outside.

The invention is directed to a dispensing device comprising a rigid container, a flexible bladder, and a rigid stopper. The container is adapted to contain a product to be dispensed. The flexible bladder is disposed below and in fluid communication with the container. The bladder comprises a top end, a sidewall extending downwardly from the top end and terminates in a spout. The bladder is in a liquid tight engagement with the container and the product contained in the container is adapted to flow into the bladder. The rigid stopper is disposed within the flexible bladder and comprises a top end, and at least one sidewall extending downwardly from the top end, and terminates in an open bottom end. The stopper comprises a plurality of through holes.

A dispenser, which has a pump chamber formed by a body including a depression, and a lid body covering an opening of the body, where a liquid in the pump chamber is discharged front a nozzle portion by performing a discharge operation that presses the lid body toward an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber when the discharge operation is released. A coil spring that urges the lid body to an outside of the pump chamber is included in the pump chamber, a diameter of the coil spring is larger than a radius of the lid body, and a deformation amount of the lid body is equal to or more than ⅓ of a diameter of the lid body.

A dispenser pump is constituted by a closure body (2), a diaphragm body (3) which forms a pump chamber with the closure body and optionally a top actuator (4) for pressing the diaphragm body (4). The diaphragm body has a deformable wall (35) formed integrally in the same polymer as its annular mounting portion (31). An inlet valve (5) through the floor (21) of the closure body has a flap (52) which is formed and hinged integrally with that floor (21). An outlet valve may also be formed in the same polymer, either integrally with the diaphragm body or as a separate component. The deformable wall of the diaphragm body is shaped to generate a restoring force itself without a separate spring, so that the entire pump may be made from the same polymer e.g. polypropylene and without metal components.

Exemplary embodiments of pumps having positive pressure venting and refill units are disclosed herein. An exemplary pump includes a liquid pump chamber, a liquid piston, a first air pump chamber, and a first air piston and a mixing area in fluid communication with the liquid pump chamber and the first air pump chamber. The exemplary pump further includes a second air pump chamber and a second air pump piston. The second air pump chamber is configured for pumping air into a container and the first air piston and the second air piston move in unison.

A trigger-type liquid ejector including an ejector main body and a nozzle member. The ejector main body includes: a longitudinal supply tube portion; a trigger mechanism including a trigger portion; a reservoir cylinder; a reservoir plunger; and a reservoir valve. The longitudinal supply tube portion includes an outer tube and an inner tube. A recovery passage is provided between the outer tube and the inner tube. The reservoir valve is provided in the inner tube and configured to allow supply of a liquid from the longitudinal supply tube portion into the reservoir cylinder by being elastically deformed in the vertical direction.

The present invention relates to a dispensing head (1) for a dispensing device, and to a dispensing device (100) for the metered dispensing of liquid preparations, which dispensing device is provided with the dispensing head. The dispensing head comprises a special valve (6), which comprises at least one sealing lip (7a, 7b), by means of which a passage channel (3) for dispensing the liquid preparation, which passage channel is formed in the dispensing head, can be closed. The present invention is characterized by the simplicity of the dispensing head (1) and the economic advantages in the manufacturing which are linked to this simplicity.

A pump container includes: a container body in which contents are accommodated; a pump unit which is coupled to the top part of the container body and ejects the contents accommodated in the container body; a head part which is coupled to the top side of the pump unit and has a contents-moving hole that causes the contents delivered from the pump unit to move upward; a button part which is coupled to the top side of the head part, operates the pump unit according to a user's press, and has a nozzle formed on one side thereof for ejecting the contents, delivered via the contents-moving hole, to the outside; and a pressure-reducing check valve which is disposed between the pump unit and the contents-moving hole and opens or closes the contents-moving hole according to a press on the button part.
