The invention concerns a device for packaging and delivering a liquid product, comprising a container deformable by pressure applied on its side walls, wherein said liquid to be delivered is stored, said container being closed by a head for dispensing the liquid product which is traversed by an outlet for the liquid product. The device also comprises a liquid drawing tube whereof one end is fixed proximate the outlet for the liquid, the tube being of such length that its other end is proximate the base of the container. The wall of the container comprises cavities partly delimiting the outline of the dispensing head. The invention is characterized in that at least one passage is provided proximate the dispensing head to ensure an air intake into the container after the liquid is dispensed, so as to allow the container to recover its initial shape by replacing by volume the dose of liquid delivered.
摘要:
A method of assembling pushbuttons for a liquid dispensing system, in which each pushbutton comprises an actuation body and at least one other component assembled with said body in a given position, said method making provision for using bodies on which a positioning cavity is formed, and continuously supplying a station for assembling the bodies and the other components by means of a path for conveying said bodies, said path having a complementary profile intended to cooperate with the cavities in order to carry out the positioning of said bodies in said conveying path, so as to carry out the assembly of the other components on the bodies thus positioned during their conveying to the assembly station. The invention also concerns an installation for implementing this method, and a pushbutton assembled by implementing said method.

Fastening device including a fastening sleeve including a plate, a skirt which has an intermediate portion including internal and external surfaces, and an end portion including internal and external surfaces, the end portion being movable between a free state, in which the external surface of the end portion projects towards the outside in relation to the external surface of the intermediate portion, and a deformed state, in which the internal surface of the end portion projects towards the inside in relation to the internal surface of the intermediate portion, a retaining ring. The fastening sleeve includes a crown having an external surface which is in axial alignment with the external surface of the intermediate portion of the skirt.
摘要:
A sleeve for the sealed fastening of a dispensing member in the neck of a bottle for the conditioning of a liquid product to be dispensed, the sleeve having an external skirt intended to be locked onto the outer wall of the neck and an internal reinforcement wherein the dispensing member is intended to be fixed in a sealed manner, the internal reinforcement having two exterior surfaces respectively lower and upper, each of the surfaces having an interference diameter allowing for the sealed clamping of the surface onto an inner wall of a neck, the diameter of the surfaces being different in such a way that the sleeve allows for the sealed fastening of a dispensing member indifferently onto two types of necks.
摘要:
The invention relates to a pump intended to be mounted on a bottle so as to enable a liquid contained in said bottle to be dispensed, said pump including a pump body, an atomizer secured to a push button, a means for the elastic return of the translatory motion of said atomizer in said body, and a plunger mounted in frictional contact against the internal surface of said body so as to define a dosing chamber which is in communication with the liquid by means of a clack valve, wherein the plunger is mounted coaxially around the atomizer in an association zone, said association zone being arranged so as to enable sealed swiveling between the plunger and the atomizer.
摘要:
The invention relates to an airless dispenser which is used to dispense low doses of liquid products. The inventive dispenser is characterised in that it consists of: a first part comprising a spray nozzle which is communicated with a network of channels on the wall of an inner truncated-cone-shaped bore, and a second part comprising a deformable container which equipped with a rigid flange for fixing the first part in the aforementioned bore. The outer periphery of the flange comprises an inclined surface which defines a vortex chamber, opposite the above-mentioned network of channels, and which, together with the wall of the first part, forms an internal peripheral outlet groove. The outlet groove is defined radially by a flexible lip forming an inlet valve which is supported by the first or second part.
摘要:
A device for encasing a system for dispensing a liquid product, provided mainly with an evacuation conduit, the downstream end of which opens to the outside, characterised in that it includes, on the one hand, a compartment respectively delimited by a back wall and a front wall with an outlet orifice in it and, on the other hand, at least one elastic return element supported by the said system on the side opposite the downstream end that can retract such as to allow the said system to be inserted in the said compartment and can then rest against the back wall to as to insert and maintain the end of the said conduit in the outlet orifice.
摘要:
A spray device for mounting on a fluid dispenser connected to a tank; the device being of the type comprising a head provided with an expansion chamber into which the outlet orifice of said dispenser opens out; the expansion chamber communicating with a nozzle via at least one outlet duct. The nozzle is constituted by a hinged inner element which is at least partially received in the outlet duct, and by an outer element fixed to bear in sealed manner against the inner element so as to define between their respective contacting surfaces a network of swirl-inducing channels communicating with the outlet duct and opening to the outside via a spray orifice formed through the outer element.
