A trigger-type ejector includes: a pressure storage chamber formed in a nozzle head and communicating with a flow path through a communication hole; a pressure storage plunger including a large-diameter pressure receiving portion opposite a small-diameter pressure receiving portion and being movable between a close position where an ejection hole is closed and an open position where the ejection hole is opened; and a biasing member disposed in the pressure storage chamber and biasing the pressure storage plunger toward the close position, the trigger-type ejector being configured such that, when a pressure of a liquid in the pressure storage chamber becomes equal to or greater than a predetermined value, the pressure storage plunger moves from the close position to the open position against a biasing force of the biasing member and thus a liquid in the pressure storage chamber is ejected from the ejection hole to the outside.

To provide a trigger sprayer that can maintain uniformity of a chemical solution containing fine powder and is superior in flow efficiency. The trigger sprayer of the present invention is designed such that a piston part 5 is moved by a pivotal movement of a trigger part, while being attached to a container, so as to apply a pressure to a liquid inside a cylinder part 42A of a cylinder structural part 4 so that the liquid in the container is jetted from a nozzle part 3 through a passage P. An F valve 2 attached to a bottom part of the cylinder part 42A serving a passage between the cylinder part 42A and the container and an S valve 1 installed in a passage part P between the cylinder part 42A and the nozzle part 3 are installed, and the F valve 2 is constituted by a cylinder-shaped base part 22 and a second valve body 21 having a sealing function as well as a small spring 22A coupling the cylinder-shaped base part 22 and the second valve body 21 to each other, and the second valve body 21 is further provided with a lower face part and a tilt part 21A on an opposite side, and the lower face part is fitted into the bottom part of the cylinder part 42A to be fixed therein, with the second valve body 21 being resiliently made in contact with a second valve mount 42A1 formed on the bottom part of the cylinder part 42A, and by pushing the tilt part 21A of the second valve body 21 by the bottom part of the piston part 5, the second valve body 21 is tilted so that one portion thereof is separated from the second valve mount 42A1, thereby opening the valve.

A foam spray can includes a motor pump, a foaming tube, a can body, a cover body and a quick release structure. One end of the foaming tube is connected to the motor pump. The can body contains liquid. The cover covers an opening of the can body. The quick release structure includes a first and a second engaging structures disposed on the cover body and the can body, respectively. The first engaging structure can be engaged with the second engaging structure along a first direction. The first engaging structure can be separated from the second engaging structure in a moving distance less than a half circumference of the opening of the can body along a second direction opposite to the first direction. Therefore, the cover body and the cover body of the foam spray can be quickly assembled and disassembled.

The present application relates to the design of a class of beauty products that facilitates personalized replenishment. The physical product is a new type of dispenser comprising a pump assembly and a sleeve or housing for containing a replaceable cartridge of a specific type of product, such as a foundation. The cartridge is an air-less cartridge that may be releasably secured to the dispenser or pump assembly such that a user may remove the cartridge from the dispenser or pump and replace the cartridge with another cartridge containing the same or a different product.

A delivering device (1) is described, in particular for pasty or creamy products preferably for domestic use, comprising at least one delivery duct (3) which puts in fluid communication at least one internal volume (5) of at least one container (7), the internal volume (5) containing therein at least one product, and at least one delivery nozzle (9) for exiting the product by interposing pumping means (11) actuated by at least one actuating motor (13) to transfer amounts of the product from the internal volume (5) to the delivery nozzle (5) through the delivery duct (3), and control means (14) actuated by a user and operatively cooperating with the actuating motor (13) to allow or inhibit at will an operation of the actuating motor (13) and perform or stop a delivery of the product through the delivery nozzle (9).

Disclosed are a single-material all-plastic pump and a storage bottle applied thereby, mainly including a plastic pressing head, a plastic pump casing, a plastic piston mechanism and a plastic reset spring; the plastic pressing head is in a pressable connection with the plastic pump casing, and has a discharge hole which is connected and communicated with a discharge end of the plastic piston mechanism; the plastic piston mechanism is disposed inside the plastic pressing head and the plastic pump casing, has a feed end which is connected and communicated with a material guide hose, and is used to control the opening and closing of the discharge hole and the material guide hose; the plastic reset spring is sleeved outside the plastic piston mechanism and compressed between the plastic pressing head and the plastic pump casing; and therefore, materials used in the solution are generally plastic, soft rubber, etc.

A foam dispensing container (100) has a container body (40) that reserves a liquid agent (L); a head part (30) that has an outlet (20), and dispenses the liquid agent (L) delivered from the container body (40) through the outlet (20) into foam; and a pump head part (32) that allows dispensing of a predetermined amount of the foamy liquid agent (foam) through the outlet (20) each time it accepts a user's operation. The outlet (20) is formed with a contiguous geometry narrowed from an intended shape. A foam, dispensed through the outlet (20) as a result of a single or multiple operations of the pump head part (32), is built up into the intended shape in a plan view seen in the dispensing direction.

Disclosed is a pump dispenser comprising: a body defining a hollow interior and an opening through which at least a portion of a refill cartridge containing a flowable substance is receivable into the hollow interior; a lid; and a pump for pumping the flowable substance from the refill cartridge when the portion of the refill cartridge is in the hollow interior and the lid closes the opening. The lid comprises a dip tube with a lumen fluidly connected to the pump, the dip tube has a tapered end located in the hollow interior when the lid closes the opening. At least one of the body and the lid has a grip on an exterior surface thereof for aiding relative movement of the body and the lid to access the hollow interior when the lid closes the opening. Also disclosed is a system comprising the pump dispenser and the refill cartridge.

A fluid dispenser comprising a dispenser member (1), such as a pump, a dispenser head (14), such as a fluid applicator, and a fluid reservoir (2) that is connected in leaktight and removable manner to the dispenser member (1), the fluid dispenser being characterized in that the sealing between the dispenser member (1) and the fluid reservoir (2) is obtained by coaxially sliding leaktight radial contact that is interrupted when the fluid reservoir (2) is disconnected from the dispenser member (1), such that the fluid reservoir (2) is connected in leaktight manner to the dispenser member (1) over a determined axial height range.

Air purge device for an airless liquid product dispenser having a container equipped with means for sampling the product. The device has a bleed ring that has a deformable lip seal accommodated inside a protective part designed to be inserted into the container. The deformation of the lip when mounting the air purge device in the container causes the air to be purged from the container.
