A leakproof gas-liquid mixing pump has a lower shell body, a pressing member and an upper shell body, the lower shell body has a liquid channel part and an outer shell part, the pressing member has a pressing part, a liquid guiding part and a first spring, the upper shell body surrounds the pressing member and is connected to the outer shell part and the liquid container. The leakproof gas-liquid mixing pump solves the problem that the gas-liquid mixing pump of the state of the art will leak when used upside down.

The present disclosure relates to a cosmetic container wherein a holder side portion has holder engaging protrusions formed on the inner surface thereof so as to face each other, left deformation assistance long holes are formed in straight shapes in left areas of the holder engaging protrusions, respectively, so as to extend from the lower end to positions higher than the holder engaging protrusions, and right deformation assistance long holes are formed in straight shapes in right areas of the holder engaging protrusions in parallel to the left deformation assistance long holes, respectively, so as to extend from the lower end to positions higher than the holder engaging protrusions. Accordingly, the inner container can be replaced easily.

A cosmetic container according to an embodiment of the present invention may reduce a thickness of the container by improving a structure of the disc value.

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 from a nozzle portion by performing a discharge operation that presses the lid body to an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber by releasing the discharge operation. The dispenser includes a pressing support portion disposed to face the lid body, and a discharge operation is performed by pinching a top portion of the lid body and the pressing support portion with fingers from lateral sides of the body.

A dispenser for dispensing a liquid product, the dispenser comprising a housing, a pump assembly, a dispensing head, and an inner container. The inner container accommodates the liquid product and is configured to be inserted into a cavity of the housing. The inner container is replaceable and detachably connected to the housing such that the housing, the pump assembly, and the dispensing head can be retained for reuse while the inner container can be replaced with a new inner container. A protrusion is provided on an underside of the inner container that a user can grip to rotate the inner container in a clockwise or anticlockwise direction to disengage the inner container from the housing.

A pressing mechanism for miscellaneous packs dispensing fluidic products comprising a capsular body in which a hollow actuator stem is slidably mounted to perform downward and upward movements with the outflow and backflow provided by a bellows with an elastic memory. An upper end of the bellows is coupled to a corresponding part of the actuator stem by a locking ring, and is also coupled to a button/nozzle, while the lower end of the bellows is supported on the capsular body. The actuator stem is slidably guided by an annular cap, below which the lower end of the actuator stem is coupled to a piston and a first check valve, which, together with a second check valve, allows the actuation of the actuator stem.

A pump for a fluid product having a pump body held in place by a valve holder fastened in the pump body; a piston sliding around a rod, provided with an inner axial channel axially closed on the lower side of the rod and communicating with the outside of the rod via a radial orifice, the piston having an outer sealing lip and an inner sealing lip; a gland having upwards an oblique or frustoconical surface of inclination appropriate to that of the inner sealing lip of the piston; an actuating spring between the rod and piston; and a return spring between the valve holder and the rod, urging the piston towards its rest position. The valve holder has an axial sleeve having an axial rib forming a mechanical stop in the actuating position between the lower axial end of the rod and the rib.

A trigger sprayer assembly is provided. The assembly includes an engine having a piston chamber and a fluid passage that extends from an inlet portion to an outlet portion, a piston having a plunger that is disposed within the piston chamber, and a trigger lever that is configured to pivot between a neutral position and an actuated position. The assembly further includes an input valve and an output valve configured to control unidirectional fluid flow through the inlet and outlet portions of the fluid passage. The input valve includes a cylindrical body terminating in a flap portion. Pivotal movement of the trigger lever from the actuated position to the neutral position pulls the plunger out of the piston chamber such that the flap portion of the input valve pivots from a closed position to an opened position and fluid flows through the input valve and into the piston chamber.

The present disclosure relates to a spring for a pumping-type container having a first helical part and a second helical part, and a pumping-type container including the same, and has been made to solve a problem caused by independent elastic deformation of the first helical part and the second helical part.

The cosmetic container includes: a housing provided to be brought into close contact with an opened upper end of a container body and having a hole formed in a central portion thereof to communicate with an interior of the container body; a pumping member provided inside the housing to be connected to the hole, having a content accommodation space defined therein, and configured to be elastically compressed or expanded along an axial direction to transfer the contents in one direction along an axial direction; and a nozzle member coupled to the pumping member and having an internal conduit to allow the contents to move, and configured to connect the pumping member and the outlet, compress the pumping member with an operation of the discharge head, and selectively open or close between the inner conduit and an internal space of the pumping member.
