A spray pump is disclosed. A spray pump according to one aspect of the present invention comprises: a housing having an inlet space and coupled to a container inlet; a housing cover coupled to an upper end of the housing; a disk for opening or closing the housing according to a pressure of the inlet space; a valve movably inserted inside the housing cover and having a valve head, a valve passage formed in the valve head, and a valve body; a guide having a portion inserted into the valve body and another portion located outside the valve body, and including a guide passage corresponding to a flow passage through which content is discharged; a pump spring for providing an elastic force for urging the valve upward; a piston movably inserted into an outer circumferential surface of the guide, and opening or closing the guide passage by means of an upward and downward movement of the valve; a nozzle having a coupling protrusion coupled to the valve head and in communication with the valve passage; a valve ball positioned inside the nozzle and capable of closing the upper end of the valve passage; and a pump spring for urging the valve ball downward.

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.

In a pump assembly, the outer wall of the first inner-housing sidewall, the inner wall of the second inner-housing sidewall and the inner-housing top wall define a first chamber with a first opening, and the gas chamber of the first chamber is a sealed chamber collectively defined by the piston portion, the inner-housing top wall, the outer wall of the first inner-housing sidewall and the inner wall of the second inner-housing sidewall, so that the formation of the sealed chamber does not require an additional sealing ring. This thereby reduces the risk of gas leakage due to aging of the sealing ring. A container with contents discharge function provided by this disclosure can include the above pump assembly.

A fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

The present invention relates to a cosmetic container provided with a pump including a part made of a polyketone material, wherein the pump functions to pump a cosmetic to the outside and has some part made of the eco-friendly material polyketone, whereby the problems of odor generation and harmfulness of formaldehyde, which is a raw material for the conventional substance polyacetal (polyoxymethylene (POM)), can be eliminated to give the user neither an unpleasant feeling nor irritation, thus allowing the user to use the cosmetic safely.

A a fixed quantity discharge device for a liquid container is provided. The device includes a container main body in which contents are accommodated, a pipette part including a pipette tube to suction and discharge the contents accommodated in the container main body, and a support disposed in an upper portion of the container main body and including a coupling part formed in an upper end portion thereof to be coupled to the pipette part, a tube accommodation part extending from the coupling part to an interior of the container main body such that the pipette tube is inserted into or withdrawn from the tube accommodation part, and a contents inflow hole formed in a lower end portion thereof to communicate with the interior of the container main body, wherein, when the pipette part is separated from the support, the contents accommodated in the container main body may be suctioned into the pipette tube.

Liquid dispenser having a liquid store and a discharge device fitted thereto and having a discharge opening. The discharge device has a pump device with a pump chamber variable in terms of volume and connected at an input side in a communicating manner to the liquid store and at an output side in a communicating manner to the discharge opening. The pump device conveys liquid from the liquid store to the discharge opening. The discharge device has a ventilation channel, by which an incoming air flow is enabled for pressure compensation between the liquid store and a surrounding atmosphere. The ventilation channel has a ventilation valve openable by manual actuation of the pump device and closed when the pump device is not actuated. Further, the ventilation channel has a capillary channel portion through which the incoming air flow reaches the liquid store.

The invention relates to a dev ice for applying a viscous substance, in particular for the purposes of cosmetics, writing, painting, drawing, and/or marking, with a tank (40) for tire substance, an application apparatus (2), and a conveying device (3), which is configured such as to convey the substance out of the tank (40) to the application device. According to the invention, provision is made for the conveying device (3) to comprise a cylinder (10), a piston (30) arranged such as to be axially displaceable in the cylinder, a pump plunger (20) for the axial displacement of the piston (30), a first connection channel (41) between the cylinder (10) and the tank (40), and a second connection channel (21) between the cylinder (10) and the application apparatus (2), the piston (30) to be adjustable in relation to the pump plunger (20), for the piston (30) to open or close the first connection channel (41) depending on the setting in relation to the cylinder (10), and for the piston (30), depending on the position in relation to the pump plunger (20), to open or close the second connection channel (21).

The present invention disclosed herein relates to a bead discharge pump container, in particular, a bead discharge pump container, which has a cylinder-type pump structure having a check valve and designed by changing a check valve structure, a piton rod structure, a gap between a piston rod and a seal cap, and the like such that the bead contents are easily discharged without being burst.

A spray structure for a portable atomizer includes: a case including an opening; a cover exposed through the opening of the case; a head portion placed in the case and coupled to the cover, the head portion including a discharge hole; and an elastic portion between the head portion and the cover, wherein the cover is configured to be rotated on a first axis by a first angle above the head portion to expose the discharge hole through the opening of the case and to be linearly moved in a second direction perpendicular to the first axis in a state in which the discharge hole is exposed.
