A pump for spraying liquid according to one aspect of the invention can include a housing having an interior space for holding a content; a guide that moves up and down within the interior space and has an inlet hole connecting with the interior space; a piston that moves with the guide while maintaining contact with the housing and the guide and is capable of closing the inlet hole; a valve coupled to and connecting with the guide and protruding to the exterior of the housing; a shoulder coupled to an upper portion of the housing; and an elastic member having one end contacting the shoulder and the other end contacting the valve to provide an elastic force pushing the valve upward, where the elastic member can include a center portion and deformation portions formed as an integrated body such that the elastic member is capable of elastic deformation.

In one embodiment, a self-cleaning nozzle comprises a nozzle body, a sleeve surrounding a proximal end of the nozzle body, a pillar disposed within the nozzle body and a spring. The nozzle body may have a hollow cylindrical interior. The nozzle body may include an orifice formed in a distal end of the nozzle body, a shoulder formed on a proximal end of the nozzle body, and a first bearing surface on an outer lateral face of the shoulder. The sleeve may include a second bearing surface on an inner face of the sleeve and a retaining lip formed at a distal end of the sleeve. The retaining lip may define a distal end of an annular space between the sleeve and the nozzle body. The shoulder may define a proximal end of the annular space. The pillar may have a distal tip configured to interface with the orifice, thereby forming a liquid seal. The spring may be captured within the annular space, thereby biasing the distal tip of the pillar into contact with the orifice.

Provided is an airless compact container. The airless compact container blocks air from flowing into a refill container through a pumping member and thus prevents contents from being corrupted by inserting the refill container provided with the pumping member into one side of a middle case and then allowing contents to be discharged to the upper surface of a content outlet part through the pumping operation of the pumping member when a user pressurizes the lower end portion of the refill container.

A non-metal pump type cosmetic container according to an embodiment of the present invention may efficiently process recycling after use. Also, Due to an operation of the elastic pump that is more flexible than a rigid metal spring, pumping may be achieved and thus a cosmetic material may be sensitively discharged even by a small force, leading to increases in tactile sensitivity and operational sensitivity. In addition, the structure of the elastic pump formed of resin having a relatively good deformation property is improved such that the elastic pump delicately may descend without being distorted during deformation, contributing to an improvement in product reliability according to a precise operation of each component.

The present invention relates to a foundation container comprising a pump having convenient pressurization and, more specifically, to a foundation container comprising a pump having convenient pressurization, wherein the outer wall of a pump main body is formed in the shape of an inwardly concave janggu (a Korean traditional hourglass drum), thereby not delimiting a pumping method to vertically pressurizing the center of a pump upper body, but facilitating the discharge of the contents even though any region of the pump upper body is pressurized. In addition, the present invention relates to a foundation container comprising a pump having convenient pressurization, wherein productivity is improved due to easy mass production by integrating a pump upper body and a pump main body in one body and forming a discharge valve and a suction valve in the same shape so as to simplify the structure of a pump.

A pump for a receptacle (10), in particular a bottle intended to contain a cosmetic product. The pump (1) has a pumping chamber (8) with a variable volume defined at least partly by a deformable membrane (3). The pump (1) functioning by varying the volume of the chamber (8) by elastic deformation of the membrane (3) between an initial state in which the chamber (8) has a maximum volume and a deformed state in which the volume of the chamber (8) is minimum. The chamber (8) being provided with an inlet orifice (22) and an outlet orifice for the product. The pump (1) has a means for deforming the membrane configured to exert a pressure on the membrane (3) and a guide rod (20) passing through the membrane (3). The membrane (3) slides along the rod (20) when it undergoes said deformation.

An oral care implement including a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom; a reservoir, in the body, for storing an oral care fluid; and a pump for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises a first check valve downstream of the reservoir, and a second check valve downstream of the first check valve and upstream of the fluid outlet. One of the first and second check valves comprises a valve seat defining an opening through which the oral care fluid is flowable, a valve member separate from the valve seat and comprising a stopper movable linearly relative to the valve seat, and a resilient element separate from the valve member and biasing the stopper towards the valve seat.

A metering dispenser for simultaneously or selectively discharging two media, including an outlet opening, a first reservoir for a first medium, a first metering-conveyor device for conveying the first medium from the first reservoir, a second reservoir for a second medium, a second metering-conveyor device for conveying the second medium from the second reservoir, a mixing chamber arranged upstream of the outlet opening and in which the first medium, conveyed by the first metering-conveyor device, and/or second medium, conveyed by the second metering-conveyor device, is stored temporarily, and an output-conveyor device for conveying the medium or media from the mixing chamber to the outlet opening. The first metering-conveyor device has the form of a metering-pump device with a variable-volume metering chamber, an inlet fluidically connected to the first reservoir and having an inlet valve, and an outlet fluidically connected to the mixing chamber and having an outlet valve.

A fluid dispenser device including an outlet, a pocket having an interior volume for containing a fluid, the interior volume being delimited at least in part by a movable wall, a reservoir arranged to contain the fluid, a pocket cap, a cavity, a reservoir orifice joining the reservoir and the cavity; wherein the pocket cap is arranged to be mounted by insertion in the cavity of the device so as to be mounted by extending: —by passing through the pocket at least partially while passing through the movable wall or—by going along the pocket at least partially, the device comprising an inlet orifice arranged to insert the pocket cap into the device from the outside of the device and opening into the cavity.

Provided is a compact container. The compact container includes: an outer container 10; an outer container lid 20 hinged to one side of the outer container 10 so as to be opened and closed; an inner container 30 mounted inside the outer container 10; a discharge device 40 for discharging a cosmetic material; a discharge plate 50 formed adjacent to the discharge device 40 and having a discharge port 52; and a fixing member 60 including a lower fixing member 62 and an upper fixing member 64 to fix the discharge plate 50, wherein the discharge plate 50 is insert-molded between the lower fixing member 62 and the upper fixing member 64, and a top surface of the lower fixing member 62 and a bottom surface of the upper fixing member 64 are integrally molded with each other at an outside of the discharge plate 50 through insert molding.
