A trigger head for a dispensing device for at least two substances including a pumping system to compress the substances separately and simultaneously before dispensing.

The present invention relates to a pump for discharging contents, which is coupled to a vessel (V) for accommodating the contents and discharges the contents, is configured such that: a suction valve plate (40) closes a content inlet (32) as the volume of the temporary repository (TR) inside the pump main body (10) decreases and pressure is generated in the temporary repository (TR) when the pump upper body (20) is moved downward by pressing the upper surface of the discharge valve (50) or the pump upper body (20); as the valve protruding ring (52), which is in contact with a content outlet (22), is widened due to the pressure, the contents in the temporary repository (TR) pass thorough the widened gap between the content outlet (22) and the valve protruding ring (52) and also pass through a flow path (24), which is the gap between the pump upper body (20) and the discharge valve (50).

A trigger-type liquid dispenser includes valve member, which is provided in flow path to control liquid to flow in direction in flow path. Valve member includes intake-side check valve, which permits flow of liquid from container side to pump side and prevents flow of liquid from pump side to container side, and discharge-side check valve, which permits flow of liquid from pump side to nozzle side and prevents flow of liquid from nozzle side to pump side. Discharge-side check valve is formed in umbrella shape that is elastically deformable freely in radial direction and has outer circumferential end configured to contact inner circumferential surface of flow path, with contact force of outer circumferential end with respect to inner circumferential surface of flow path being distributed non-uniformly in circumferential direction.

A dispenser includes a depressible thermal tip and a housing having a reservoir for containing a product, such as a cosmetic product or a medicinal product. The depressible thermal tip comprises a thermal applicator displaceable between open and closed positions. The thermal applicator may be depressibly coupled in a collar fixed to the housing, or the thermal applicator may be depressibly coupled in a button depressibly coupled in a collar fixed to the housing.

A cost-effective metering dispenser configured to allow at least one component accommodated in a container, in particular in cartridge form, to be metered by a pumping unit, having an inlet valve, an outlet valve and a pumping cylinder as well as a pumping piston, which is inserted in the pumping cylinder and can be activated by an actuating element. The dispenser is economical to produce because of the straightforward construction of the pumping unit, that can be arranged in a sleeve, which continues the container and is formed in one piece with the container.

A trigger head for a dispensing device for at least two substances including a pumping system to compress the substances separately and simultaneously before dispensing.

The present invention provides a compact container including a pump having a short stroke distance, which includes a container body 10 formed at one side thereof with a button 11 and a container lid 20 hinge coupled to one side of the container body 10, the compact container including; an inner container 30 formed therein with a content receiving space 31; a pump support plate 40 coupled to a top of the inner container 30 to seal the inner container 30 and provided at a center thereof with a cylinder 51; and a pump 50 installed on a center top part of the pump support plate 40 to pump a content and having a stroke distance of 1.5 mm to 2.5 mm, in which a ratio between the stroke distance and an inner diameter of the cylinder 51 is 1:5 to 1:13.

A pump assembly is provided according to an embodiment of the present invention. The pump assembly may comprise: a cylinder having a suction port formed through the lower end thereof; a piston ascended and descended inside the cylinder and having an inlet formed through one side thereof; a seal cap ascended and descended inside the cylinder, in a state of coming into close contact with the inner wall of the cylinder, to open and close the inlet; a stem coupled to the piston in such a way as to be ascended and descended together with the piston and having an outlet formed on top thereof; a cylinder cap coupled to the upper side of the cylinder to surround the stem; a first elastic member disposed between the seal cap and the stem inside the cylinder; and a second elastic member disposed between the cylinder cap and the stem outside the cylinder.

A spray pump is provided where two seal caps are arranged in an upper portion and a lower portion within a cylinder housing so as to prevent the contents from leaking, the cylinder housing a wall surface with one or more leakage discharge holes so that the content which can be accumulated within the cylinder housing is discharged through the leakage discharge holes rather than a content flow path, thereby enabling an efficient operation.

A perfume bump valve needle unit has a valve needle, piston, spring and valve rod. A bump body unit has a valve needle unit, bump body, glass bulb and inner stopper. A bump head unit has an alumina press cap, spay chip and head cap. A valve rod external diameter between the inner piston and stopper has a Y-shaped spring with an end fixed to a recess and hold. A piston limit is at the valve needle head; an opposing needle bar sets into the rod centre hole. A ring recess at the valve needle bar end snap-fits with a rod inner diameter ring buckle. The valve needle external diameter has an effluent trough from the ring recess to the head. A piston internal ring and rod external diameter fit and seal. A channel between trough and piston open when the rod, piston and valve needle move to the bulb.
