A valve block assembly for a bottle attachment apparatus for handling liquids has a valve block, an intake valve insert and/or an exhaust valve insert, and a valve receptacle assigned to the respective valve insert. The valve insert is inserted in a replaceable and sealing manner in the valve receptacle. The valve insert has a stop portion, a fastening portion distinct therefrom and a sealing portion distinct from both. The associated valve receptacle has stop, fastening, and sealing portions matching the equivalent portions of the valve insert. When the valve insert is installed correctly both the stop portions and the sealing portions bear on one another in a planar manner.

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.

An apparatus (100) for metered dispensing of a liquid from a container (3) and a spray applicator having the apparatus (100). The apparatus (100) comprises a base body (5) and a nozzle body (16) having an outlet nozzle. The nozzle body (16) is mounted so as to be displaceable relative to the base body (5) from a dispensing to a clamping position. The apparatus (100) comprises a reset spring (14) for moving the nozzle body (16) from the clamping to the dispensing position. The nozzle body (16) and the valve body form a burst chamber (19). By pressure on the trigger mechanism (26), the locking of the valve body (10) is triggered and the spray burst spring (7) presses the valve body (10) in the nozzle direction. A non-return valve is arranged upstream in the valve body. The spray burst chamber is connected to the outlet nozzle.

The invention relates to a cosmetic container capable of adjusting the amount of content dispensed. A cosmetic container according to one aspect of the invention comprises: an outer container that holds a content; a handle that is rotatably coupled to an upper portion of the outer container; an adjustment member that is coupled to an upper portion of the handle to rotate as an integrated body with the handle and is provided with a downwardly protruding pressure protrusion; and a pump that is configured to suction and dispense the content held in the outer container and is configured such that a pressing on a portion thereof by the pressure protrusion changes an amount of content dispensed, where rotating the adjustment member adjusts a discharging amount of the pump by adjusting the extent to which the pressure protrusion presses the pump.

A dual dispensing pack includes a dual dispensing pump head having a first pumping assembly and a second pumping assembly. The first pumping assembly is operatively coupleable to a first bottle and the second pumping assembly is operatively coupleable to a second bottle. The first pumping assembly includes a first piston, and the second pumping assembly includes a second piston. A stroke length of the first piston is the same as a stroke length of the second piston, and a volume dispensed by the first pump assembly is independently varied from a volume dispensed from the second pump assembly.

A fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

A dispensing device for fluid products includes a draw-up pipe, a main body and a dispensing head. The main body includes a pumping system, connected to the draw-up pipe and a fastening ring nut, for fixing the dispensing device to a container for fluid products. The fastening ring nut and the pumping system are mutually coupled for forming between them an air compensation duct which allows the selective passage of air from the outside towards the inside of the container during the operation of the dispensing device. The dispensing head in turn includes a cup, which has in a relative lower portion a passage, and a valve, housed in the lower portion of the cup, configured to adopt a first configuration, or open configuration, wherein the passage is put in fluid communication with the pumping system and a second configuration, or closed configuration, wherein the passage is occluded.

In one embodiment there is provided a bottle assembly to dispense a liquid. The assembly includes a bottle, a syringe, a cap and collar. The assembly includes a child-resistant adult-friendly retaining portion to permit the removal of the cap and collar. The syringe is configured to draw liquid from the bottle at a precise dosage and then when the cap and collar is removed the user can expel the liquid.

Pump dispenser comprising a pump and a container for liquid to be dispensed, the pump comprising a pump body mounted in the neck of the container and a plunger reciprocable relative to the pump body to alter the volume of a pump chamber defined in the pump body and having an inlet and an outlet, the outlet leading through an outlet passage to a discharge opening. The pump cylinder body is retained at the container neck. A vent is provided in the cylinder body wall adjacent the neck edge. A vent block ring is disposed in the cylinder body adjacent the vent, and is moveable between blocked and unblocked positions relative to the vent. The vent block ring has an integral upward projecting formation which is engaged by part of the plunger in a locked-down position of the plunger, so that when the plunger is locked down the vent block element blocks the vent, while in a relatively extended position of the plunger the vent block element is in the unblocked position.

An initial positioning system and method for liquid measuring and taking. The system comprises a measuring passage, a variable pressure chamber, and a piston, an initial end of the measuring passage being in communication with the upper part of the variable pressure chamber; the piston reciprocates in the variable pressure chamber to cause a change between positive pressure and negative pressure in the variable pressure chamber; the initial positioning system further comprises a pressure relief port located on the wall of the variable pressure chamber and capable of communicating with the outside of the variable pressure chamber; when the piston is located at the pressure relief port, and the inside and outside of the variable pressure chamber are in communication, the maximum volume of the liquid that can be accommodated in the variable pressure chamber is not smaller than one third of the total volume of the variable pressure chamber.
