A new all-plastic micro miniaturized spray gun. Inner hole of miniaturized spray gun piston bush includes lower elastic sleeve; upper and lower ends of piston cavity in inlet hole of body include upper and lower thru-hole; upper elastic sleeve disposed above inner hole of piston bush in inlet hole on body between upper and lower thru-hole; upper elastic sleeve abutted against piston bush and fixed in inlet hole of body; diversion groove is disposed on inner walls of inlet hole on body; which is tapered and corresponds to upper elastic sleeve; which includes piston and cover; lower thru-hole of body is normally open; when upper thru-hole of body drives piston to move inwardly through wrench, lower elastic sleeve is stressed subject to pressure change, controlling opening or closure of inlet hole on body, and upper elastic sleeve is deformed subject to pressure change, opening or closing upper thru-hole of body.

A fixed nozzle pump appropriate for food service and dispensing of other fluids of varying viscosities is contemplated. The components are modularly connectable for easy assembly and cleaning. A piston and sealing ring cooperate with the chamber extension formed in the pump body to facilitate reciprocating pump action while minimizing the number of components disposed in and exposed to the fluid flow path. A novel, injection-moldable valve is integrated on the dispensing nozzle. The entire assembly may be disposed within a container shell which itself includes a replaceable pouch filled with the fluid to be dispensed.

A dispensing system (2000), includes a container (900) containing a flowable base formulation (910) to be dispensed, an additive mixing device (2004), and an actuable pump engine (2002) which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body (2022) with an internal cavity (2052), an additive ingredient (2054) within the cavity, and a flow path/mixing chamber (2058) between an input and an output. With each pump of the device (2004) the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices (2004) may be interchangeable for different formulations, and the mixing devices may be refillable.

A wound irrigation device including a container with an opening along the outer surface of the container and a nozzle assembly coupled to the container and configured to selectively allow the liquid to exit the container when pressure is applied to the container.

A dispenser, which has a pump chamber formed by a body including a depression, and a lid body covering an opening of the body, where a liquid in the pump chamber is discharged from a nozzle portion by performing a discharge operation that presses the lid body to an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber by releasing the discharge operation. The dispenser includes a pressing support portion disposed to face the lid body, and a discharge operation is performed by pinching a top portion of the lid body and the pressing support portion with fingers from lateral sides of the body.

VALVE CARTRIDGE FOR ACTUATORS OF A RANGE OF PACKAGING, having an independent complementary valve mechanism (1) to be mounted directly on the internal region of an outlet nozzle (2) of a known actuator (3) of a usual packaging (4), which actuator is traditionally combined with a pump-type mechanism (5) for extracting the product (P) contained in said packaging (4) and, accordingly, said packaging has a seal-tight upper closing part (6) that forms the body housing the extractor pump-type mechanism (5), the upper part of which is in communication with the outlet nozzle (2), while the lower part is in communication with the inside of the packaging (4), where it produces a vacuum, negative pressure or positive pressure, sufficient to move the product (P) to the outlet nozzle (2), containing an inlet duct (7) and an outlet duct (8), and in the latter there is mounted the independent complementary valve mechanism (1) which alters said stream of the semi-solid product (P) turning it into a drip, trickle or spray.

A trigger sprayer assembly is provided. The assembly includes an engine having a piston chamber and a fluid passage that extends from an inlet portion to an outlet portion, a piston having a plunger that is disposed within the piston chamber, and a trigger lever that is configured to pivot between a neutral position and an actuated position. The assembly further includes an input valve and an output valve configured to control unidirectional fluid flow through the inlet and outlet portions of the fluid passage. The input valve includes a cylindrical body terminating in a flap portion. Pivotal movement of the trigger lever from the actuated position to the neutral position pulls the plunger out of the piston chamber such that the flap portion of the input valve pivots from a closed position to an opened position and fluid flows through the input valve and into the piston chamber.

The present invention concerns a device (1) for dispensing a fluid (L), suited to be coupled with a container (C) holding said fluid (L). The device (1) comprises a collapsible chamber (6) suited to draw, contain and dispense an amount of said fluid (L) and at least partially delimited by a deformable membrane (10) suited to be squeezed to dispense at least one portion of said amount from the collapsible chamber (6). The device (1) comprises locking means (50, 52, 56) suited to maintain the deformable membrane (10) in a fixed squeezed position and release means (80, 84a, 84b, 86a, 86b) suited to release the deformable membrane (10) from the fixed squeezed position.

The cosmetic container includes: a housing provided to be brought into close contact with an opened upper end of a container body and having a hole formed in a central portion thereof to communicate with an interior of the container body; a pumping member provided inside the housing to be connected to the hole, having a content accommodation space defined therein, and configured to be elastically compressed or expanded along an axial direction to transfer the contents in one direction along an axial direction; and a nozzle member coupled to the pumping member and having an internal conduit to allow the contents to move, and configured to connect the pumping member and the outlet, compress the pumping member with an operation of the discharge head, and selectively open or close between the inner conduit and an internal space of the pumping member.

A massage applicator for massaging cream-type fluids into the skin, provided with an end wall with a massage region, on which massage elevations are provided. The end wall is penetrated by at least one outlet channel for the cream-type fluid. The massage applicator is provided with suitable markings in the massage region for measuring the fluid to be used, the applicator is provided with a cover which can be blocked in an open position and/or secured in a closed position, and an assembly of two valves is used in order to secure against unintentional discharge.
