A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.

The Liquid Dispenser that can be worn as jewelry of the present invention includes a dispenser having a bladder assembly and an outer shell. The outer shell opens to receive the bladder assembly, which includes a flexible bladder, neck and valve. The outer shell has an opening, exposing the enclosed flexible bladder to enable a user to apply pressure directly on the flexible bladder through the opening. When a user applies pressure to the flexible bladder, liquid passes through the valve for use. In an alternative embodiment, a flexible bladder is contained within a watch base. The watch base includes a flexible watch face that when pressed by a user, applies pressure to the flexible bladder. In yet another embodiment, a pump/valve device in combination with hollow tubes that store liquid enables a user to press a flexible dome on the device to release fluid stored in the hollow tubes.

A dispensing device affixed to the outside of a flexible container. A top part of the device includes a pump dome, a pump chamber ridge, and pump chamber flange. A bottom part includes a pump chamber, a pump chamber flange, a neck portion, and a dispensing head having an outlet at the end of a dispensing channel. The dispensing channel and the outlet are situated in a portion of the dispensing head that extends below the plane of the neck portion. The top part is sealed to the bottom part creating a channel between the pump chamber and the dispensing side of the dispenser. The device is sealed to the container in two discrete areas, namely the flange of the pump chamber and the bottom of the distal portion of the dispensing head. The area of the dispensing element between the pump chamber and the distal end of the dispensing head, referred herein as the neck portion, is not sealed to the container, causing the neck portion of the dispensing device to flex, pinching shut the channel that connects the pump chamber to the dispensing head.

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.

A dispenser pump for spraying a fine mist has a plunger (2) reciprocable in a pump body (3). The plunger has a head (4) and a stem (5). A closure (8) holds the pump in a container neck, and has an external decorative crimp sleeve (82). The plunger head has a matching external trim (72). A pump spring (7) is mounted outside the pump chamber (71), around the stem above the piston thereof. A pre-compression spring (75) acts to delay opening of the outlet piston seal until sufficient pressure builds in the pump chamber (71).

A liquid soap dispenser includes a container having a flexible outer wall and including a quantity of liquid soap therein. The upper surface of the container can be moved between an upper position and a lower position but is spring biased into the upper position. A pump within said container pumps a portion of the liquid soap onto the upper surface when it is moved downwardly into its lower position. A normally closed valve at the bottom of the container opens to dispense liquid soap from the bottom of the container when the container is squeezed.

A dispensing tip assembly includes a foodstuff additive dispenser for a pressurized foodstuff container. A tip body of the dispensing tip assembly may have low pressure zone in which fluid pressure is lower than fluid pressure upstream of the low pressure zone as flowable foodstuff from the foodstuff container flows through the internal flow passage toward an open downstream end of the tip body. The dispenser tip assembly may include one or more of duckbill valves tethered to one another, and/or a plurality of injection ports and/or structure for one-direction dispensing, and/or internal fins to couple to an actuator of the foodstuff container, and/or an anti-rotation device, and/or a collar for attaching a bulb or pod of the tip body, and/or an ergonomic and functional bulb.

Some embodiments are directed to a valve made up of a rigid wall and a flap. The flap has a non-perforated flexible and deformable peripheral region situated facing the rigid wall. The rigid wall is perforated by at least one orifice situated facing the peripheral region. The flap is joined to the rigid wall by a non-deformable fixed connection. The peripheral region has a substantially conical shape before mounting with a large base and a small base and an inner face on the inner side of the cone. The peripheral region exhibits a deformation following the pressing of the inner face of the large base against the rigid wall in a assembled position.

The invention relates to a device for dispensing fluid products which is provided with an extension tip (4) connected by a first end to a nozzle (3) associated with a metering pump mounted on a bottle containing the product that is to be dispensed and comprising at its distal second end a discharge orifice, said extension tip (4) bearing a shutter (5) a first end (5A) of which is arranged on said discharge orifice, this shutter (5) being intended to open at its distal second end (5B) under the pressure of the product when said pump is actuated, and said shutter (5) comprising a tubular external part (6), elastically deformable in longitudinal bending, of which a first end (5A) is arranged on the discharge orifice and of which the tapering external cross section diminishes evenly towards its distal second end (5B), at least over part of its length, said external part (6) being intended to deform elastically in a radial direction at its distal second end (5B) under the pressure of the fluid leaving the pump via said nozzle (3). According to the invention, said shutter (5) comprises, inside said external part (6), a tubular connector (7) secured to said discharge orifice of the tip (4) and a stem (8) of cross section substantially equal to the internal cross section of the distal second end (6B) of said external part, which is connected by its first end (8A) to this connector (11) by means of an articulation and which via its second end (8B) closes the distal second end (6B) of said external part.

A fluid dispenser comprising a deformable outer shell (1) and a flexible inner pouch (2) that is arranged inside the shell (1) in such a manner as to define between them a compression space (E) that is filled with air, the pouch (2) containing a fluid for dispensing through a dispenser valve (4), the compression space (E) communicating with the outside through an air inlet valve (5), such that deformation of the shell (1) puts the air contained in the compression space (E) under pressure, the air under pressure acting on the pouch (2), so that the fluid therein is then forced through the dispenser valve (4), the dispenser also comprising a head (3) that is fitted on the shell (1) and on the pouch (2), the head (3) comprising a first valve support (34) on which the dispenser valve (4) is mounted, and a second valve support (35) on which the air inlet valve (5) is mounted; the dispenser being characterized in that it further comprises a hood (6) that is fastened in non-leaktight manner on the deformable outer shell (1), the hood (6) holding the head (3) in place on the deformable outer shell (1) and on the flexible inner pouch (21), the hood (6) including a window (63) in which the dispenser valve (4) is positioned.
