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.

Pump for dispensing a fluid

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.

Device for closing a container of a liquid to pasty product and refill closed by such a device

The present invention relates to a modular closure device () for a device for dispensing a product, comprising: &#x2014;an outlet nozzle () comprising: an outlet orifice () at the front, a rear opening, a product intake orifice, &#x2014;top valve comprising a shut-off member () that closes of the outlet orifice, a deformable membrane () 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; &#x2014;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.

Device for dispensing liquid-to-pasty products and module-forming closure device therefor

The invention relates to a device () for dispensing a product (L), comprising: an element for connection to a container (R) containing the product; a piston () that is stationary in relation to the connection element; a cylinder body that moves around the piston, thereby defining a dosing chamber (), the piston comprising a dosing inlet () for said chamber and the apex () of the dosing chamber comprising an outlet of the dosing chamber; and an inflow non-return valve () 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.

Device for dispensing a product with improved triggering

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.

Device for withdrawing and dispensing a viscous product, without taking in air

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.

Container, in particular a wide-mouthed jar, for containing a liquid or pasty material and combined with a system for collecting and dispensing without taking in air

The invention relates to a device () for dispensing a pasty liquid material () by means of a low-pressure manual metering pump (), which is provided with an system for closing an end (), and which is intended for a rigid or flexible container (), the operation of said pump being ensured by: a lower check valve () and a metering chamber () which consists of a resiliently deformable bellows () and which is in communication with an upper valve () consisting of in series: a stopper () for the channel () of the spout (), which ensures that the end () is closed; a resiliently deformable diaphragm () enabling the stopper () to be opened; an auxiliary return member () suitable for the low pressures causing the closing of the stopper (); and a sealed vessel (), characterized in that the resiliently deformable diaphragm () is combined with the vessel () that said diaphragm seals, wherein the auxiliary return member () is arranged inside said vessel so as to be permanently linked to the diaphragm (), and said vessel includes two levels () that are resiliently deformable according to various characteristics.

System for closing a device for the low-pressure dispensing of a pasty liquid material

A method for carrying out ventilation in a multi-walled container of the type comprising a rigid external housing, inside which a flexible inner pocket for containing a product is arranged and connected to a withdrawal device without ventilation, the layers having no adhesion between the same such as to be able to be separated without difficulty and with air ventilation between the same, characterized in being obtained by means of molding a projection at the upper or lower part of the pre-form which is subjected to a first operation of cutting a sprue, then a second operation of cutting the projection in a region close to the base and/or the neck of the recipient for production and a third operation of separating the layers.

Method for carrying out ventilation in a multi-walled container

A closure device for a container, particularly a bottle, has a stopper called the service cap, arranged at the end thereof, on which a closing flap pivots. The closure device is provided with a locking system and cooperates with a hole in the sealed closure, or can be opened by pivoting. The closing flap has an opening device to guarantee the complete pivoting of the closing flap on opening, by a constant force and a constant movement without manual action of the user, immediately after the same has carried out a voluntary manual operation on the closing flap which is limited to releasing the locking system thereof.

Closure cap for a bottle with controlled opening

The invention concerns a dispensing and closure system arranged at the top of a container, in particular a soft tube comprising a liquid or pasty product, which is delivered by pressing on the tube. The invention is characterized in that it consists of a valve comprising two concentric elements, one of which forms a mobile cylindrical delivery valve and the other forms a cylindrical body exiting from a plate linked to the tube. The two elements defined between them an annular gap through which the product passes. When a manual pressure is exerted on the tube, it causes the product to act directly on the delivery valve causing the latter to open, countering an elastic return member, so as to allow the product to escape from the tube, when the pressure is exerted thereon and to automatically close the delivery valve when the pressure is released, preventing the possible return of the product already dispensed from returning inside the tube.
