Definitions

the present invention relates to a dispensing device, without propellant gas, delivering by manual action doses of product, in particular cosmetic product.
One solution, to avoid contamination, is to provide a variable volume container for the product to be distributed.
This container can be a closed pocket made of a movable and deformable wall connected to a manual metering pump without air intake.
the bag decreases in volume with each dose withdrawn and dispensed by the pump, without the stored sterile product coming into contact with the outside air, which ensures that it maintains its sterility.
document WO 89/00535 describes a container with multiple walls, comprising a deformable pocket serving as a container for a product to be dispensed.
This container comprises a neck, which has an opening opening into the pocket and equipped with an element comprising a plurality of projections arranged all around this opening to form a strainer which cannot be blocked by the deformable wall of the pocket; the pocket is tightly fixed by welding to the strainer element.
the object of the present invention is to provide a dispenser capable of dispensing both liquid products and pasty products, without this resulting in a significant increase in the force to be exerted on the push button of the pump.
the bag must be able to empty itself as completely as possible of the product that it contains, for reasons of very understandable performance: thus there must be no product trapped in the folds of the bag, quine can be sucked and pushed back by the pump.
this dispenser must be of simple construction and must in particular avoid welding the deformable pocket onto the dispensing means or the strainer element associated therewith.
the present invention therefore relates to a device for dispensing a liquid or pasty product, in particular a cosmetic product, comprising a container with at least two concentric walls, the outermost of these walls forming a substantially rigid shell, the innermost of these walls forming a deformable sealed pocket of variable volume serving as a container for the product to be dispensed, the shell being provided with an orifice which maintains the ambient pressure around said pocket, the container carrying a dispensing means capable of '' sealingly sealing and being maneuvered externally to ensure the distribution of the product, this distribution means being associated with an element, which is integral with it and which opens into the pocket, the wall of the pocket having a thickness and a substantially uniform structure and said element comprising, around the opening through which it opens into the pocket, a plurality of projections regularly spaced from each other and oriented towards the bottom of the container to form a strainer which cannot be blocked by the deformable wall of the pocket.
the dispensing means is a manual pump, which delivers a dose of product to be dispensed by actuation of a push button.
each projection is a spike having a cylindrical lateral surface which is continued by a rounded end surface. This arrangement avoids any tearing of the squeezed pocket at the end of emptying on the pins, while the element described in document WO 89/00535 has sharp angles which can lead to possible drilling of the deformable pocket.
each projection is a tongue delimited by rounded faces, in order to avoid any tearing of the pocket.
the container has a longitudinal axis along which the dispensing means is arranged, the external faces of the tongues being arranged in a cylindrical geometric envelope having as axis the longitudinal axis of said dispensing means, the internal faces of said tongues delimiting a space where the opening of the element.
the tongues advantageously occupy a surface between 0.3 and 0.7 times the total lateral surface of the cylindrical envelope defined by said external faces. This surface value makes it possible to achieve a good stop for the wall of the pocket without causing excessive pressure drop in the case of the distribution of viscous products.
the end of each tongue has, on its external face, a chamfer eliminating an edge, which could have damaged the wall of the pocket.
the opening, through which the element opens into the pocket, can be disposed at a distance d1 from the bottom of the container and at a distance d2 from the zone for fixing the dispensing means to the container, the ratio d1 / d2 being understood in the range of 0.8 to 1.2; in this case, the folding of the pocket under the effect of the dispensing means takes place in an orderly and relatively symmetrical manner without any creation of a product retention zone.
the dispensing means comprises, inside the container, a body on which the element is fixed, the projections of the element connecting to a frustoconical part of said element, said part widening from the projections up to the area for fixing the dispensing means to the container.
This frustoconical part creates a guide surface of the pocket which orders, even more, the folding of the pocket.
the manual pump which has a control tube and is fixed to the container via a crimp cup through which said control tube passes.
the dispensing means comprises, inside the container, a body on which is formed a cylindrical surface, the element being traversed by a bore and coming to be fitted with hard friction on the cylindrical bearing surface of the distribution means. It is also possible that the element is in one piece with the distribution means.
a liquid or pasty product dispenser comprising a container 1 with two walls and having a longitudinal axis of symmetry XX.
the outer wall 2 of this container forms a substantially rigid outer shell.
the internal wall 3 is mobile and deformable; it has a substantially uniform thickness and structure.
This internal wall 3 forms a sealed pocket 4, of variable volume, which is housed inside the shell 2 and which serves as a container for the product to be dispensed.
the shell 2 is provided with an orifice 5 for bringing the pocket to atmospheric pressure 4.
the container has a neck 10 equipped with a distribution means 11 sealing the pocket 4 in effect.
the upper edge 12 of the pocket forms a circular ring which rests on the upper edge 13, in the form of a circular ring, of the shell 2.
the neck 10 has a rim 14 projecting radially, which comprises a frustoconical portion 15, of revolution around of the axis XX, the diameter of which decreases downward in a direction opposite to that of the orifice of the container.
the distribution means 11 is integral with a circular metal cup 21, the peripheral edge 22 of which is crimped on the rim 14 of the neck 10 of the shell 2, with the interposition of an elastic washer 20.
the edge 22 exerts pressure on the assembly constituted by the elastic washer 20, the upper edge 12 of the pocket, and the upper edge 13 of the shell; the elastic washer 20 thus serves as a seal between the edge 12 of the pocket and the metal cup 21.
This cup sealingly fixes the dispensing means 11 which is here in the form of a metering pump 26 comprising a control tube 23, the end of which is surmounted by a plunger 24 with a dispensing nozzle 25.
the axis of the tube 23 is substantially coincident with the axis of symmetry XX.
the cup 21 forms, in its central part, a cylindrical recess 30 equipped with a central hole 31 for passage of the tube 23.
the recess 30 comprises an elastic washer 32 serving as a seal between the cup 21 and the body 33 of the pump 26.
the body 33 of the pump is delimited by a continuous succession, from top to bottom, of three lateral faces forming cylindrical bearings 34, 35, 36 of axis XX.
the first 34 of these spans comprises, at its lower part, a frustoconical portion 40, decreasing towards the interior of the container; the cup 21 is crimped onto the surface 34 by compressing the elastic washer 32.
the second surface 35 has a diameter greater than the diameter of the third surface 36, which is connected to a circular end face 40 opposite the bottom of the container 1 , the suction orifice 41 of the pump opening into said face 40.
This orifice 41 opens into an element 42 disposed inside the pocket 4.
the element 42 has a circular opening 43 facing the bottom 44 of the container 1 and in fluid communication with the orifice 41 of the pump 26.
This element 42 comprises, bordering said opening 43, four tabs 45 regularly spaced one on the other and oriented longitudinally towards the bottom 44 of the container, to form a strainer which cannot be blocked by the wall 3 of the pocket 4.
Each tab 45 has a length, in the direction XX, equal to the diameter of said opening 43.
the external faces 50 of these tongues are arranged in a cylindrical geometric envelope of revolution of generatrices parallel to the axis XX.
Each tongue 45 has one end 51 having an outside chamfer 52.
the tongues 45 are separated from each other by a space having the overall shape and dimensions of a tongue.
the external faces 50 of the tongues form, in total, an area equal to half the lateral surface of said cylindrical geometric envelope.
the element 42 has an external contour of revolution around the axis XX and the external faces 50 of the tongues are continued by a first frustoconical lateral surface 53, which itself continues by a second frustoconical lateral surface 54, the two truncated cones widening towards the neck up to the zone for fixing the distribution means to the container 1.
the circular base 55 of the upper truncated cone 60 delimited by the second lateral surface 54 comes into contact with an annular projection 61 of the cup 21.
This projection 61 results from the presence of a groove 62 separating the edge 22 of the cup and its central part forming the recess 30.
the frustoconical lateral surface 54 is in continuity with the external lateral face of the groove 62 and the inside of the neck 10. This continuity allows continuous support of the wall mobile 3, when, by deformation, for example caused by the pump, it approaches element 42.
the element 42 comprises, on the other hand, a through bore 64 of axis XX, the lower end of which forms the opening 43.
the element 42 is fitted with hard friction on the second bearing 35 of the pump body , the bearing surface 35 cooperating to do this with the bore 64.
FIG. 2 shows a second embodiment of the present invention, in which only the element 180 differs from the corresponding element 42 shown in FIG. 1.
the identical structures bear reference numbers increased by 100 compared to those used for the realization of Figure 1.
the element 180 is in the form of a small segment of cylinder of revolution of height equal to twice the length of the tongues which border four in number, the opening 140
the upper circular face 170 of the element 180 has a rounded edge to avoid any catching with the deformable wall 103 of the pocket in on the contrary favoring any sliding of this wall 103 on the element 180.
This element comprises a through bore 172 of axis YY, which ends at its lower part by the opening 140.
the element 180 is fitted with hard friction by its bore 172 on the third cylindrical seat 136 of the pump 133.
FIG. 3 and 4 show a third embodiment of the invention.
the structures identical to those of FIG. 1 bear reference numbers increased by 200 compared to those used for the production of FIG. 1.
the container 201 is identical to that of FIG. 1.
the pump 226 comprises a body 233 delimits by a continuous succession, from top to bottom, of two cylindrical bearing surfaces 234, 235.
the cup is crimped onto the bearing surface 234 as described previously for FIG. 1.
An element 280 is fitted with hard friction on the lateral bearing surface 235 thanks to a bore 264 arranged along the axis ZZ of said element and of the container.
This element 280 has a circular opening 243 opposite the bottom 244 of the container and in fluid communication with the orifice 241 of the pump 226.
the element 280 comprises, bordering said opening 243, three pins 285 regularly spaced from one another and oriented longitudinally towards the bottom 244 of the container, to form a strainer which cannot be blocked by the deformable wall 203 of the pocket 204.
Each pin 285 has a cylindrical lateral surface of revolution which continues downwards through a rounded end surface 252.
the pins 285 are in one piece with a frustoconical part 286 flaring towards the neck of the container 201 and arriving in contact with the bottom of the cup 221.
This frustoconical part 286 has eight regularly spaced grooves 200 and a depth less than the diameter of the section of a pin 285.
Each groove 200 opens onto the surface of the frustoconical part 286 and is oriented along a generatrix of this surface.
the function of these grooves is to establish a set of channels where the product to be dispensed can circulate between the wall 203 of the pocket 204 and the element 280.
the manufacture of the dispensing device according to the invention can be developed in the following manner: a plurality of containers 1, 101, 201 known in the prior art are taken; they are filled with a determined volume of the product to be dispensed. Furthermore, cups 21, 121, 221 are prepared which are each crimped on a manual pump in the manner indicated above.
the elements 42, 180 or 280, forming a strainer, are force-fitted onto at least one of the cylindrical surfaces of the pump body to give a plurality of intermediate assemblies, which are each directed towards the neck of a corresponding container before to be fixed to it, by crimping the edge of the cup onto the edge of the shell of the bottle.
