Definitions

• the present invention relates to a metal crimping capsule, and a fluid dispenser device comprising such a capsule.
• Crimping by means of a metal capsule is a well-known means for fixing a dispensing member, such as a pump or a valve, to a fluid reservoir, in the fluid dispensing devices.
• a capsule generally comprises a fixing part in which the dispensing member is fixed, and a crimping part which is crimped onto the neck of the reservoir.
• a problem which can arise with this type of fixing relates to the generation of metal particles during the crimping step, that is to say when the crimping part is deformed to come and get stuck under the neck of the tank. These metal particles, even in small numbers, can have a negative effect on the dispensing member, or on the product to be dispensed. This can be particularly troublesome when the product in question is very sensitive and must in no case come into contact with any metal particle. Particles of metal are also likely to be generated before or after crimping, by impacts of the capsules against each other in the assembly units.
• Another problem which arises concerns the voluntary or accidental tearing of the pusher, which can in particular cause contamination of the product contained in the device.
• the object of the present invention is to provide a crimping cap which does not have the abovementioned drawbacks.
• the present invention aims to provide a crimping capsule for a fluid dispensing device which avoids any generation of metal particles before, during and after the crimping step.
• the present invention also aims to provide such a crimping cap which effectively and simply prevents any attempt tearing off a pusher or dispensing head connected to the dispensing member.
• the present invention also aims to provide such a crimping cap which is simple and inexpensive to manufacture and assemble.
• the present invention therefore relates to a metal crimping capsule for a device for dispensing a fluid product, said capsule acting to fix a dispensing member, such as a pump or a valve, on the neck of a reservoir containing the product.
• said capsule comprising a fixing part for fixedly receiving said dispensing member, and a crimping part which is crimped onto the neck of the reservoir, said crimping part comprising a covering element made of plastic material extending to the at least partially on the internal surface and at least partially on the external surface of said crimping part, so that no generation of metal particles occurs before, during and / or after crimping, characterized in that said covering element comprises on the external surface of said crimping part of the capsule, retention means adapted to cooperate with a pusher to retain the latter while preventing its removal from said dispensing member.
• said covering element completely surrounds said crimping part.
• said covering element is extended on the internal surface of the capsule by a radial flange forming a seal for the neck of the reservoir.
• said radial flange forming a neck seal is extended by an extension or sock, preferably approximately frustoconical, cooperating in leaktight manner with said dispensing member.
• said retention means are formed by a peripheral rib adapted to cooperate, for example by snap-fastening, with a skirt of a pusher.
• said covering element comprises recognition means making it possible to identify parameters characteristic of the device for dispensing a fluid product and / or the fluid product.
• said recognition means are visual, such as color, and / or tactile.
• the present invention also relates to a device for dispensing a fluid product comprising a dispensing member, such as a pump or a valve, mounted on a reservoir containing the fluid product, and comprising a crimping capsule as described above. to fix said dispensing member to the neck of said reservoir.
• a dispensing member such as a pump or a valve
• FIG. 1 is a schematic view in cross section of a first advantageous embodiment of the present invention
• FIG. 2 is a view similar to that of FIG. 1 of a second advantageous embodiment of the present invention.
• FIG. 3 is a view similar to Figures 1 and 2, of a third advantageous embodiment of the present invention.
• a reservoir 30 comprising a neck 31 (the reservoir does not intervene directly in the present invention, it is only shown very schematically in dotted lines in the figures).
• this crimping cap 10 has a fixing part 11 in which the pump 20 is fixed, and a crimping part 12 which is intended to be crimped on the neck of the reservoir.
• the internal structure of the pump is obviously arbitrary and does not intervene in the present invention, so that it will not be described in more detail below. It is understood that the pump shown in the Figures is only one possible example, all pumps and valves can be used in the context of the present invention.
• the capsule comprises at its crimping part 12 a covering element 15 made of plastic material, and which extends at least partially on the internal surface and at least partially on the external surface of the part of crimping.
• the covering element 15 extends completely over the internal surface of the crimping part 12 and only partially over its external surface.
• the covering element 15 completely surrounds this crimping part 12, so that the covering element forms a sort of continuous cylindrical hollow sleeve into which said crimping part 12 is inserted.
• the covering element 15 prevents any generation of metal particles in the atmosphere due in particular to impact between the capsules.
• the presence of the covering element 15 prevents any generation of metal particles in the atmosphere, and in particular near the pump 20 or the reservoir 30. In this way, there is no risk that metal particles come into contact with the product or with parts of the pump before, during and / or after the assembly and / or filling of the device.
• the covering element 15 comprises on the external surface of the crimping part 12 of the capsule 10 retention means 18 which are adapted to cooperate with a pusher (not shown), to hold it fixedly on the pump 20, and in particular prevent its removal or tearing, voluntary or accidental.
• retention means 18 can for example be made in the form of an external peripheral rib 18 which cooperates, for example by snap-fastening, with a skirt of the pusher.
• the rib may be continuous or segmented, and other equivalent retention means, such as lugs, can be envisaged.
• these means of retention are shown in the drawings at an end edge of the covering element, but it is possible to arrange them differently on the external part of said covering element.
• FIG. 2 there is shown a first advantageous variant of the invention, in which the covering element 15, which extends over the entire internal surface of the crimping part 12 of the capsule 10, is extended by a radial flange 16 which advantageously forms the seal which cooperates with the upper edge of the neck 31 of the reservoir 30.
• this radial flange 16 forming a neck seal is further extended by an extension or sock 17, which is intended to cooperate sealingly with the pump 20.
• a sock 17 is well known, in particular to avoid contact of the product with the vent hole of the pump, and it will therefore not be explained in more detail below.
• said sock 17 is approximately frustoconical, but other embodiments are obviously possible.
• the present invention therefore provides a covering element 15 which not only provides the advantage of avoiding the generation of metal particles, but also comprises means for retaining the pusher.
• the covering element can also form a collar seal and / or a sock.
• said covering element 15 may further comprise recognition means which make it possible to identify characteristic parameters either of the device for dispensing a fluid product or of the fluid product itself.
• these recognition means can be visual, for example a particular color, a set of colors, or an external pattern which allows the user to visually identify the parameters in question by simply looking at the outside of the crimp cap.
• means of tactile recognition formed for example by bosses or other means easily recognizable by the user when touched.
• characteristic parameters which can be identified by means of said covering element 15 there may be mentioned in particular the type of product to be dispensed, the quantity contained in the reservoir, the dosage of the product, the volume of each dose dispensed by the pump, the type of device use, etc.
