A fluid dispensing device having a flexible fluid pouch and a dispensing assembly, the dispensing assembly having a top piece and a bottom piece, the top piece having a flexible actuator including a flexible dome and a flexible flange extension, the bottom piece having a bottom portion of a pump chamber, a pump chamber inlet, a chamber inlet valve, and a bottom portion of an outlet valve, the top piece and the bottom piece mated together to form a pump chamber and an outlet valve, said device configured to allow bidirectional fluid flow through either or both inlet and outlet valves, and to dispense a volume of fluid that is less than the volume of said pump chamber. The flexible pouch may have a single opening or two openings. In the case of a single opening, the entire dispensing assembly is in the interior of the pouch. In the case of two openings, only the flexible dome extends to the exterior of the pouch. The outlet valve is configured so that the more pressure that is applied to the flexible fluid pouch, the more tightly the outlet valve seals.

The invention relates to a jar comprising: a body having an upper wall, a flexible pouch containing a product to be dispensed, a deformable chamber delimited by a rigid wall and a flexible diaphragm and in fluidic communication with, for the one part, the flexible pouch and, for the other part, a dispensing orifice that opens out at the upper wall, a lid mounted on the upper wall so as to be movable between an open position and a closed position, the movement between these positions consisting of the lid being slid over the upper wall, pressurizing means designed to press on the flexible diaphragm while the lid moves from the closed position to the open position.

Provided is a dispenser for pasty products having a fixed head that has a dispensing duct for dispensing a product, a pump with an elastically deformable cap, a manually-operated actuator, a separating wall with a suction inlet, and a suction valve cooperating with the suction inlet. The suction valve has a valve body and a plurality of tabs that bend and open the suction inlet in a product suction step, and close the suction inlet in a product dispensing step.

A head (10) of a trigger dispenser device includes a bulb (70) having an elastically deformable casing (72) that includes a vent lip (90), molded in one piece. With the casing (72), the vent lip (90) forms a venting valve.

The present invention relates to an applicator having a press button for discharging gel-type contents, and more specifically, an applicator having a press button for discharging gel-type contents, the applicator comprising: a pump embedded in a container body; a pressing member coupled to the upper side of the pump; a link coupled to the pressing member; and a press button formed on the outside of the link. If the press button is pressed, the link is pressed, then the pressing member connected to the link presses the pump vertically, and thereby the gel-type contents filled in the container body are pumped, and discharged through a discharge member. Thus, a predetermined amount of gel-type contents can always easily be discharged for use.

A dispenser head (10) of a trigger dispenser device includes a self-bearing pre-compression valve (80), made of polypropylene, capable of per se retaining in a stable manner to the head frame (14).

A valve assembly with a valve member coaxially received within a valve casing and interacts with the casing to provide a one-way inlet valve at one end of the valve casing and a one-way outlet valve at the other end of the casing with an annular compartment therebetween adapted to be coupled to a variable volume compartment and thereby together provide a simplified construction for valving components of a fluid pump.

A fluid dispensing device having a flexible fluid pouch and a dispensing assembly, the dispensing assembly having a top piece and a bottom piece, the top piece having a flexible actuator including a flexible dome and a flexible flange extension, the bottom piece having a bottom portion of a pump chamber, a pump chamber inlet, a chamber inlet valve, and a bottom portion of an outlet valve, the top piece and the bottom piece mated together to form a pump chamber and an outlet valve, the device configured to allow bidirectional fluid flow through either or both inlet and outlet valves, and to dispense a volume of fluid that is less than the volume of the pump chamber. The flexible pouch may have a single opening or two openings. In the case of a single opening, the entire dispensing assembly is in the interior of the pouch. In the case of two openings, only the flexible dome extends to the exterior of the pouch. The outlet valve is configured so that the more pressure that is applied to the flexible fluid pouch, the more tightly the outlet valve seals.

A manually operable head assembly for a dispenser for pasty products which has a fixed head with a dispensing duct for dispensing a product, a pumping unit with an elastically deformable cap, an actuator, a guarantee tab connected to the fixed head and having a tab body, and at least one bridge connected to the actuator is provided. The at least one bridge is suitable for breaking on a first operation of the actuator. The tab body is configured to remain connected to the fixed head following the first operation of the actuator.
