A pump and a dispensing device with a pump for dispensing a preferably liquid product are proposed, wherein the pump comprises a spring sleeve for a spring, which separates the spring from the product, and/or wherein the pump comprises a sealed spring chamber for a spring.

The present invention relates to a powder dispensing container. When a button is pressed, a piston formed in close contact with the inner wall of an external housing is lowered so that air in the external housing is moved to an inner housing and discharges powder flowing into the internal housing, thus it is possible to always dispense the powder consistently regardless of the amount of the powder stored in a container body.

A receptacle for mixing different kinds of materials includes an outer receptacle for holding cosmetic contents; a shoulder member of a cylindrical member with the upper and lower portions opened, which is screw-coupled to an upper opening portion of the outer receptacle; a pump coupling member of a disk-shaped member coupled to the inner circumference of the shoulder member, which couples a first pump set and a second pump set side by side; an inner receptacle of a cylindrical member, an upper flange of which is placed between a lower surface of the pump coupling member and an upper surface of the upper opening portion of the outer receptacle, which is partitioned into a first and a second space portions, into which a first and a second pump sets are inserted from the upper part, respectively.

A pump assembly comprises a pump main body having a first cavity and a press rod. The press rod has a rod body and a piston portion in which the rod body is slidably provided in the first cavity in a penetrating manner and one end thereof extends out of the first cavity. The piston portion is connected to the rod body and is located in the first cavity to divide it into a first gas cavity and a second gas cavity, one or more of which are sealed cavities. Since the piston portion can rebound under the resultant force of a gas pressure in the gas cavities, the pump main body does not need a spring for rebounding the rod body. Accordingly, the pump assembly can be entirely made of a plastic material, and no metal material is mixed, so the pump assembly is easily recycled.

Dispenser systems, dispensers, and repositories can add a fragrance to an unscented liquid beauty preparation. The dispenser system includes a dispenser having a cavity for retaining at least a first liquid, and a repository configured for removably attaching to the dispenser, the repository having a reservoir for retaining at least a second liquid. The dispenser is coupled with a pump assembly including at least one pump for drawing the at least a first liquid and the at least a second liquid into a mixing chamber. The mixing chamber is coupled with an actuator in such a manner that when the actuator is pressed down by an external force, the mixing chamber communicates with the pump to suction the first and second liquids into the mixing chamber to form a liquid mixture for dispensing through a nozzle.

A dispenser includes a housing, an inverted container disposed in the housing, a outlet nozzle, a pump, a first check valve, and a second check valve. The pump is disposed between the container and the outlet nozzle. The pump includes a pump inlet a pump outlet, and a pump chamber. The pump chamber is movable between an expanded position and a compressed position. The first check valve is disposed between the pump and the outlet nozzle, and the first check valve has a first cracking pressure. The second check valve is disposed between the first check valve and the outlet nozzle, and the second check valve has a second cracking pressure. The second cracking pressure of the second check valve is greater than the first cracking pressure of the first check valve.

Provided is a fluid container including: a container main body, of which one side is open, configured to store a fluid; a housing having an outlet provided at one side and in which the container main body slides in a longitudinal direction; and a pump module coupled to the open one side of the container main body and configured to discharge the fluid to the outlet by sliding the container main body.

A multilayered container (100) includes an inner container configured to contain content, and an outer container (7) configured to accommodate the inner container, wherein the inner container has a side surface formed with a plurality of folded pleats contractable and expandable in a vertical direction, so that the inner container is shrinkable inside the outer container (7), wherein the inner container includes a metal layer or an inorganic layer, and wherein a discharge mechanism (50), configured to discharge the content, and including a mechanism configured to prevent air from entering the inner container when discharging the content, is attached to an upper surface of the inner container.

An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and upper and lower loading cones received at opposing upper and lower ends of the slotted tubular spring element. The upper loading cone may be axially compressible towards the lower loading cone within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions. In some dispenser configurations, the lower loading cone may be stationary or fixed within the dispensing head and the upper loading cone may be downwardly compressible toward the lower loading cone by movement of a nozzle head.

Provided is a powder discharging container. The powder discharging container includes a container main body in which powder is stored, a button part which is disposed at an upper side of the container main body to be pressed by a user and which has a discharge hole formed at one side, a stem which is configured to ascend or descend according to whether the button part is pressed and which has a movement hole formed inside an upper portion to communicate with the discharge hole, a path forming part which is disposed inside the stem, communicates with the inside of the container main body, and has a powder movement path in which the powder moves and an air movement path in which air moves formed therein, and a compression chamber part which is coupled to lower portions of the stem and the path forming part, has a chamber formed therein to store air, and is configured to, as the button part is pressed, inject the air inside the chamber into the movement hole through the air movement path, wherein, as the air is injected from the chamber into the movement hole due to the button part being pressed, the powder inside the container main body moves through the powder movement path and the movement hole and is discharged to the outside through the discharge hole.
