Definitions

• the present invention relates to a device for dispensing a fluid product, and more particularly to a multifunction tank produced in a single piece.
• Fluid product dispensing devices are well known. They generally comprise a reservoir containing the product to be dispensed, a dispensing member, such as a pump or a valve, mounted on said reservoir, and a dispensing head for actuating said dispensing member. Depending on the type of product in the tank, the dispensing device must include a certain number of characteristics, for example means to avoid any contamination of the product contained in the device.
• this device generally comprises a neck seal disposed between the neck of the reservoir and the fixing element which fixes the dispensing member to this reservoir. The establishment of this seal generally requires an additional assembly step and therefore complicates it increasing the manufacturing and assembly costs of the device.
• the object of the present invention is to provide a device for dispensing a fluid product which does not have the abovementioned drawbacks.
• the present invention aims to provide a fluid dispensing device which is simple and inexpensive to manufacture and assemble, and which makes it possible to integrate into a single piece several functional characteristics promoting proper operation of the device .
• Another object of the present invention is to provide a device for dispensing a fluid product in which the number of component parts is reduced to a minimum.
• the present invention therefore relates to a device for dispensing a fluid product comprising a reservoir containing the fluid product, a dispensing member, such as a pump or a valve, for dispensing the product contained in said reservoir, and a dispensing head. for manually actuating said dispensing member, said tank being a multifunction tank made in one piece and comprising at least one of the following elements: (a) at least one orifice adapted to receive at least one filter for filtering the air entering the inside the tank after each actuation of said dispensing member; and (b) a neck seal molded onto the neck of said reservoir.
• the reservoir further comprises at least a first radial projection cooperating with said dispensing head to prevent any tearing of said head.
• said reservoir further comprises at least one second radial projection cooperating with said dispensing head to define a stop with said head during actuation thus defining the actuation profile of the device, said at least one second radial projection being spaced axially with respect to said at least one first radial projection.
• said at least one filter received at said at least one orifice is snapped on, welded or overmolded on said reservoir.
• said at least one orifice adapted to receive said at least one filter is produced in a side wall of the tank.
• said tank is produced by injection blowing with a synthetic material, such as a thermoplastic material.
• a synthetic material such as a thermoplastic material.
• said overmolded neck seal is made of injected thermoplastic elastomeric material (TPE), the reservoir and the overmolded seal being produced by bi-injection blow molding.
• TPE thermoplastic elastomeric material
• the upper radial surface of the reservoir comprises a receiving profile adapted to receive said overmolded seal.
• FIG. 1 is a partial schematic view in cross section of a device for dispensing a fluid product according to a first embodiment of the present invention
• Figure 2 is a view similar to that of Figure 1 showing a second embodiment of the present invention
• Figure 3 is a view similar to that of Figures 1 and 2 showing a third embodiment of the present invention
• FIG. 4 is a schematic view similar to those of FIGS. 1 to 3, showing a device integrating the three embodiments of FIGS. 1 to 3.
• the present invention applies to all devices for dispensing a fluid product comprising a reservoir containing the product to be dispensed, a dispensing member, such as a pump or a valve, mounted on said reservoir in any known manner, and comprising a dispensing head or actuating pusher mounted on said dispensing member for actuating this in order to distribute the product contained in the tank.
• Figures 1 to 3 separately show three separate embodiments of the present invention, but it is obvious that the present invention also covers any combination of these three embodiments.
• FIG. 4 shows in particular a variant integrating the three embodiments described in FIGS. 1 to 3.
• the figures very schematically represent a device comprising a reservoir 10 on which is mounted a dispensing member 20, in this case a pump.
• the dispensing member 20 could be produced differently from a pump, for example in the form of a valve.
• a dispensing head 30 (or manual actuation pusher) is assembled on the pump 20 to actuate the latter manually. To do this, the user generally presses axially on a part of the head, which has the consequence of moving the piston of the pump inside the body of the latter, in order to dispense a dose of product contained in the tank.
• the pump 20 can be fixed to the reservoir 10 by means of any fixing ring, for example crimpable, as shown in the drawings, snap-on or screwable.
• a multifunction tank 10 which is made in one piece, and which may have one or more functional characteristics as will be described below.
• the reservoir 10 may include at least a first radial projection 11 which is adapted to cooperate with the dispensing head 30, and more particularly with a radial shoulder 31 provided in the lateral skirt of said dispensing head 30. As can be seen in FIG.
• the first projection 11 can also be used to define the stop position at the top dead center of the dispensing member, namely the rest position of the device.
• the assembly of the dispensing head around the reservoir 30, and in particular of the projection 11 can for example be done by snap-fastening of the shoulder 31 on said projection.
• the projection 11 can be formed by a continuous annular flange or by one or more separate projections cooperating with the head 30.
• the reservoir can also comprise at least one second radial projection 12 which is also adapted to cooperate with the dispensing head 30 in order to define an abutment therewith during actuation. More specifically, this optional second radial projection 12 makes it possible to define the actuation position of the device, and it is therefore obviously spaced axially with respect to the first radial projection 11, to allow movement of the head 30 between these two projections 11 and 12.
• this second projection 12 can also be used to achieve a transport security function, for example by cooperating with a removable clip provided between the head and said projection.
• One or both radial projection (s) could also be used to define a
• FIGS. 2 and 4 show a reservoir comprising at least one orifice 15 adapted to receive at least one filter 50 for filtering the air entering inside the reservoir 10 after each actuation of the pump 20.
• This orifice 15, which is a vent hole, is advantageously made in a side wall of the tank 10, and may include a profile for receiving the filter 50, which can for example be snapped on, welded or molded onto said tank 10, at the level of this profile.
• Figures 3 and 4 show a reservoir 10 having a neck seal 18 molded onto the neck 19 of the reservoir 10.
• This implementation simplifies the assembly process of the pump 20 on the reservoir 10, in that the neck seal is already prepositioned on the tank by being molded on it.
• the neck 19 of the reservoir 10, and in particular the upper radial surface of the reservoir 10 comprises a receiving profile 17 adapted to receive said overmolded seal 18.
• a particular advantage of the present invention is that the multifunction reservoir 10 is made of '' a single piece by molding or injection blowing.
• this reservoir is made of a synthetic material, such as a thermoplastic material.
• this seal can be made of injected thermoplastic elastomeric material (TPE), the reservoir 10 and the molded seal 18 then being produced by bi-injection blow molding.
• TPE thermoplastic elastomeric material
• the three embodiments shown in Figures 1, 2 and 3 may be combined in any desired manner to provide a one-piece multifunction tank for performing several functions simultaneously being formed in one 'part. This is in particular shown in FIG. 4.
• the present invention therefore makes it possible to limit the number of component parts of a dispensing device
