Abstract:
The invention relates to a device (1) for dispensing a product (L), comprising: an element for connection to a container (R) containing the product; a piston (3) that is stationary in relation to the connection element; a cylinder body that moves around the piston, thereby defining a dosing chamber (100), the piston comprising a dosing inlet (35) for said chamber and the apex (64) of the dosing chamber comprising an outlet of the dosing chamber; and an inflow non-return valve (5) with a membrane for opening or closing the dosing inlet, the piston being in two parts, one of which forms a sealing joint with the cylinder body, the piston and the inflow non-return valve forming separate parts and being arranged such that the membrane is tightly clamped to the top of the piston.
Abstract:
The present invention relates to a modular closure device (7) for a device for dispensing a product, comprising: —an outlet nozzle (9) comprising: an outlet orifice (15) at the front, a rear opening, a product intake orifice, —top valve comprising a shut-off member (17) that closes of the outlet orifice, a deformable membrane (22) that seals the rear opening closed, designed so that a depression inside the nozzle forces the shut-off member toward its closed position, and a rigid frame extending between the outlet orifice and the membrane; —a bell housing having an end wall and base opening opposite this end wall, the edges of the base opening being fixed to the nozzle, the membrane sealing the base opening closed. The invention also relates to a dispensing device comprising this closure device.
Abstract:
A container for containing a liquid or pasty material which is combined with a system for collecting and dispensing without taking in air. The container is rigid and includes a flexible bag which contains the material to be dispensed and which is combined with the collecting system. The bag is produced separately from the rigid container and has an overall cylindrical reservoir which is open at the top portion thereof and which is divided into four areas defined by a rigid upper sidewall, a flexible deformable lower sidewall, and a fillet connecting the flexible side wall to a base.
Abstract:
A device for withdrawing and dispensing a viscous product without taking in air is described. The device on the one hand includes a pumping member positioned, by its base, at the open end of a rigid container associated with a retractable flexible inner pouch, intended to receive the product, and on the other hand a plunger tube connected by its upper end to a corresponding part of the pumping member, such that the upper end is partially submerged in the product and the free lower end is completely submerged in the product, such that the plunger tube is made up of a first upper part, with a closed circumference, defining a reference section of the tube and a second lower part submerging the first, with a circumference open by at least one longitudinal slot, made along a generatrix and defining a C- or U-shaped section on that part of the tube.
Abstract:
A pump for dispensing a fluid, has a pump head, a piston body with a piston, a pump chamber limited by a pump chamber body, an inlet valve and an outlet valve, the piston being moveable by respective movement of the pump head between an upper starting position and a lower end position. A return stroke force for a return stroke from the lower end position into the upper starting position is provided by a bellows, formed by two bellows arranged one above the other, Each of the bellows is folded up, when moving the pump head into the lower end position, by exerting a compression force on the pump head, the first bellows receiving the compression force by direct engagement with the pump head, the second bellows receiving the compression force only by engagement with the first bellows.
Abstract:
The invention relates to a closure device comprising a closure wall having a communication conduit passing through it and intended to close the opening of a container of a product and a stopper movable in the duct. The stopper comprises a cavity open on one side of the wall, closed by a bottom and comprising at least one lateral opening. In the closed position, this bottom closes the conduit, and in the open position, the side opening(s) and said bottom exit the conduit, the conduit thus being open in fluid communication through the stopper. The invention also relates to a product refill comprising a container closed by this closure device. It also relates to a dispensing device comprising this refill and a dispensing head.
Abstract:
A device for withdrawing and dispensing a viscous product includes a pumping member and a dip tube that includes an upper end connected to a corresponding portion of the pumping member. The dip tube includes a lower portion having a free lower end, with a circumference of the lower portion opened by at least one longitudinal slot formed parallel to a longitudinal axis of the dip tube, wherein the longitudinal slot forms a gutter with a bottom, the lower portion includes pins arranged inside the gutter and extending transversally to the longitudinal slot and away from the bottom of the gutter, the pins being dispatched along the longitudinal slot.
