Provided is an elastic member according to an embodiment. The elastic member includes an upper support, a lower support provided under the upper support, and at least one elastic part configured to connect the upper support to the lower support, wherein the elastic part includes an upper support portion formed downward from the upper support, a lower support portion configured to extend upwardly from the lower support, and a connecting portion configured to connect the upper support portion to the lower support portion with a predetermined inclination and to be bent and deformed when the elastic member is pressed.

The present invention relates to a cosmetic container using an eco pump, and the eco pump effectively controls pressure acting on a space between a container body and a container lid, thereby preventing liquid leakage from the space between the container body and the container lid to the container lid. The cosmetic container using the eco pump includes a container body, a cover, a connection tube and a check valve which effectively block and release liquid contents discharged from the container body, an eco pump made of an elastomer material, and first to fourth cylinder members and a container lid discharging the liquid contents to the outside via a discharge path of a lid or blocking the liquid contents from the outside.

The disclosure relates to a dispenser pump (10) for manual dispensing of product (2) in fluid form out of a container (3) and for leakproof assembly to an opening (3A) of the container by means of a closure (4). The dispenser pump comprises a housing (20) adapted for being held fixed in relation to the container after assembly. The housing defining a pump chamber (21) with an inlet (22) configured for fluid communication with the inside of the container. The dispenser pump comprising at least one spring (30) and an actuator (40) configured for fluid communication with the inside of the pump chamber and a piston rod (42) fixedly connected to the actuator and arranged for reciprocating motion inside the pump chamber. The disclosure further relates to a spring (30) for a dispenser pump (10).

A double container includes: an inner container adapted to store a given content therein and having a neck formed on top thereof; an outer container adapted to accommodate at least a portion of the inner container therein; a neck cap coupled to the neck of the inner container and having at least a portion accommodated in the inner container; pump assemblies coupled to top of the outer container, detachably coupled to the outer peripheral surface of the neck cap, having at least portions accommodated in the neck cap and inserted inside the inner container, and adapted to discharge the content therefrom; and a nozzle adapted to be pressurized by a user to discharge the content transferred from the pump assemblies through a discharge hole.

Disclosed is the invention of a pump dispenser wherein a deformation prevention locking part induces a chaplet to move in the axial direction in a housing at the time of rotation of a head part, thereby allowing or restricting an operation of pressing a head part while preventing the deforming of an elastic member. The disclosed pump dispenser comprises: a cap part fastened to a container; a housing which is provided at the cap part and in which a content stored in the container remains in a dischargeable state; a shaft received in the housing so as to be movable in the axial direction, the shaft including a head part for discharging the content remaining in the housing to the outside through a pressing operation by an external force; a chaplet provided in the housing such that the shaft is inserted so as to be able to extend therethrough, the chaplet allowing or blocking the movement of the shaft on the basis of the angle of rotation of the head part; an elastic member provided on the circumference surface of the shaft and elastically supporting the chaplet and the head part; and a deformation prevention locking part for inducing the chaplet to move in the axial direction in the housing at the time of rotation of the head part, thereby allowing or restricting an operation of pressing the head part while preventing the deformation of the elastic member.

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 trigger sprayer includes an engine with a piston chamber and an outlet fluid passage, and a piston that slides within the piston chamber and defines an interior bellows chamber. The bellows component is movable in the interior bellows chamber between an uncompressed position in which a fluid volume in the interior bellows chamber is minimized and a compressed position in which the fluid volume is maximized. The trigger sprayer further includes a trigger lever that pivots between a neutral position and an actuated position using a pair of S-shaped trigger springs. Pivotal movement of the trigger lever pushes the piston vertically in the piston chamber to drive fluid from the piston chamber into the interior bellows chamber and move the bellows component from the uncompressed position to the compressed position. Relaxation of the bellows component drives fluid from the interior bellows chamber to the outlet fluid passage.

A double container includes: a nozzle for discharging a content through a discharge hole under pressurization of a user; a pump assembly for discharging the content under the pressurization of the nozzle; an inner container having a first accommodation portion adapted to accommodate the content therein and a first edge portion formed on top of the first accommodation portion to accommodatedly seat at least a portion of the pump assembly thereonto; an outer container having a second accommodation portion adapted to accommodate the inner container therein and a second edge portion formed on top of the second accommodation portion; and a shoulder detachably coupled to the second edge portion of the outer container and adapted to pressurize the inner container through the coupling to the outer container to allow the inner container to come into close contact with the outer container, wherein the outer container may be made of glass.
