Definitions
- the present invention relates to a portable device for dispensing a fluid substance (liquid or pasty), intended in particular for dispensing, with or without spraying, a cosmetic product, a perfume, a medicament or the like. More particularly, the invention relates to such a device equipped with a pump, generally actuated using a finger of one hand or possibly actuated automatically.
- fluid substance distribution pumps are known, for example those described in documents FR-A-2 305 241, FR-A-2 314 772 (and corresponding document US-A-4 025 046), FR- A-2 343 137, FR-A-2 403 465 (and corresponding document US-A-4 245 967), FR-A-2 399 286 and EP-A-0 486 378.
- These pumps include a cylindrical pump body hollow in which a piston slides, the pump body and the piston delimiting a pump chamber.
- the pump chamber communicates with an inlet passage via an inlet valve, and with an outlet passage via a silk valve.
- the inlet valve can be a non-return valve or a slide valve, which closes by relative sliding of two parts when the piston is moved from a rest position.
- the piston is also controlled by an actuating rod which is biased towards its rest position by a return spring.
- the pumps are manufactured by a specialist company, then sent to other companies (which we will call conditioners: pharmaceutical laboratories, manufacturers of cosmetics or perfumes, etc.) where they are mounted on tanks (glass or plastic, metal can, etc.) previously filled with the substance to be dispensed.
- conditioners pharmaceutical laboratories, manufacturers of cosmetics or perfumes, etc.
- the pump body has an open end through which the internal organs of the pump are mounted.
- This mechanical connection between the pump body and the stop member is generally only useful for transporting and storing the pump before it is mounted on the tank, so that it represents an unnecessary additional cost (additional operation in the manufacturing process, for example se ⁇ issage, or complexity of parts).
- the present invention therefore aims to solve the following technical problems:
- a device for distributing a fluid substance comprising:
- a pump having a pump body mounted in the opening of the reservoir, the pump body forming a hollow cylinder having a longitudinal axis, and said pump body extending axially between an open end which is directed towards the outside of the tank and an inlet end which comprises an intake duct communicating with the tank, the pump further comprising an annular piston which slides axially with seal in said cylinder, the pump further comprising an actuating rod which slides axially with sealing in the piston and which has a first end projecting axially out of the open end of the pump body, the pump further comprising a return spring which biases the rod actuation towards the open end of the pump body, the pump further comprising a stop member which limits the movement of the actuating rod towards the open end of the pump body, the pump comprising a pump chamber in beam which is delimited by the pump body, the actuating rod and the piston, and which is compressed when the actuation is moved from its rest position, the actuation
- an external sleeve which slides in the piston, which is biased by the return spring, which abuts against the stop member, and which is axially traversed by a central channel
- an internal rod which is adapted to be fixed to the external sleeve by interlocking with sealing in the central channel of the external sleeve, the internal rod comprising the first end of the actuating rod as well as a second end which cooperates by mutual interlocking with the intake duct for closing the intake duct, when the actuating rod is moved from its rest position, said internal rod being adapted to be mounted in the external sleeve by fitting after assembly of all the aforementioned parts of the device , b) the stop member is fixed to the reservoir, and c) the reservoir comprises means for limiting the movement of the pump body towards the interior of the reservoir.
- the device is delivered to the packer in two parts: the internal rod on the one hand, and the rest of the assembled device, on the other hand.
- the stop member is fixed to the reservoir, which keeps the pump assembled while avoiding a direct mechanical connection between the stop member and the pump body.
- the stop member keeps the pump mounted on the tank. Due to the fact that the second end of the internal rod constitutes the inlet valve of the pump, the intake duct remains permanently open before mounting the internal rod. Therefore conditioner can easily fill the tank through the central channel of the outer stem of the actuating sleeve.
- the final assembly of the pump, after filling, is very simple, since it consists simply in fitting the internal rod into the central channel of the external sleeve of the actuating rod.
- the stop member When the stop member is snapped in, it is particularly useful that its fixing is irreversible, or at least that the stop member cannot be removed without damage by simple manual pulling on the actuating rod, for the purpose avoid not only involuntary dislocations of the device, but also fraud or subsequent filling of the tank after complete emptying.
- the opening of the reservoir is delimited by a cylindrical longitudinal lateral surface of revolution which has a periphery having two or three circular sectors hollowed out regularly distributed and separated by circular sectors not hollowed out, each hollowed-out circular sector forming an angle of at least 60 ° at the center of said opening, said hollowed-out sectors defining a shoulder which is directed towards the interior of the tank and which forms with said lateral surface an angle less than or equal to 90 °, and the abutment member comprises an elastic collar flared towards the outside of the reservoir, said elastic collar having, when it is not deformed, an external diameter greater than the diameter of said lateral surface, to cause an expansion of said flange in the circular recessed sectors when said flange is fitted into the opening of the reservoir.
- the opening of the reservoir comprises two hollow circular sectors each forming an angle of at least 90 °.
- this expansion mounting of an elastic collar is not specifically limited to the fixing of the abutment member of the above-mentioned device, but may be applied to the irreversible fixing of any dispenser body in a tank opening. : it suffices that the opening of the reservoir has a shoulder forming a stop for the body of the distributor and recessed circular sectors, and that the body of the distributor or a separate stop member has the elastic flange.
- the abutment member when the pump operates with air intake and the reservoir is non-deformable, provision may be made for the abutment member to be in tight peripheral contact with the reservoir and the external sleeve of the actuating rod is in peripheral contact. watertight with the stop member, when said external sleeve abuts the stop member, the internal rod of the actuating rod being separated from the stop member by an annular air intake passage, the body of pump comprising an external axial groove which communicates the interior of the tank with said annular air intake passag.
- the external sleeve of the actuating rod comprises at least one part which projects radially inside the abutment member to allow said external sleeve to move against the action of the return spring, when the internal rod is not mounted in the external sleeve.
- the return spring is a compression spring, mounted between the piston and the external sleeve, and said return spring biases the piston towards the inlet end of the pump body, the pump body having a piston stop which limits the movement of the piston towards the inlet end.
- the return spring is mounted between the external sleeve and the pump body, and the pump also comprises a second spring mounted between the external sleeve and the piston to urge the piston towards a position where it obscures the lateral opening of the actuating rod.
- the return spring is mounted between the piston and the pump body to urge the piston towards the open end of the pump body
- the pump also comprises a second spring, which has a higher stiffness to the return spring and which is mounted between the piston and the external sleeve to urge the external sleeve towards the open end of the pump body.

- the tank has a cylindrical shape of revolution with a side wall 1a which extends axially between an open end 2 and a bottom 1b.
- the reservoir 1 has internally a shoulder 3, directed towards the open end 3 of the reservoir, and moreover, between the shoulder 3 and the open end 2, the inner surface of the side wall has a circular periphery which has two recessed circular sectors 17 diametrically opposite and separated by two non-recessed circular sectors 18, as can be seen in FIG. 3.
- two recessed circular sectors 17 diametrically opposite and separated by two non-recessed circular sectors 18, as can be seen in FIG. 3.
- the hollowed-out circular sectors 17 form an angle ⁇ at the center of the side wall la which is greater than approximately 60 °, and preferably greater than approximately 90 °.
- the recessed sectors 17 can be 3 in number, although this is less preferred.
- the reservoir 1 is molded from plastic and the hollow sectors 17 are obtained by means of two parallel recesses 27 which pass through the reservoir 1 perpendicularly to its axis of revolution, and which can be easily made by means of two sliding rods in a tank injection mold.
- the recessed sectors 17 each define a shoulder 19, which is directed towards the inside of the tank and which forms with the inner surface 20 of the side wall 1a angle substantially equal to 90 ° or possibly less.
- the hollowed out sectors 17 can be produced by hot knurling if the tank is made of glass.
- the device further comprises a pump which has a pump body 4 fitted into the tank 1, and which rests against the shoulder 3 of said tank 1. All the parts of the pump are generally made of plastic , with the exception of springs, generally metallic.
- the pump body 4 defines an inner hollow cylinder 5 which has a longitudinal axis 5a and said pump body 4 extends axially between an open end 4a directed towards the open end 2 of the reservoir, and an inlet end 4b which comprises an intake duct 8 communicating with the reservoir 1 via a dip tube 28.
- the intake duct 8 advantageously comprises an inner peripheral sealing lip 8a.
- the dip tube 28 is shown as being formed in one piece with the pump body but it could be more conventionally fixed to the pump body.
- the pump also comprises an annular piston 6, which slides with sealing inside the cylinder 5.
- the pump further comprises an actuating rod 7, 12, which is formed of two parts which will be described in more detail below.
- the actuating rod extends axially between a first end 12a which projects axially out of the open end 4a of the pump body, and a second end 12b which is adapted to selectively block or open the intake duct 8, by fitting inside the sealing lip 8a of said intake duct.
- the second end 12b comprises a guide rod 12c which slides permanently without sealing in the lip 8a and a wider part 12d, adapted to penetrate into the lip 8a with sealing.
- the actuating rod 7, 12 further comprises a blind outlet duct 13 which opens axially at the first end 12a of the actuating rod and which opens laterally through a lateral orifice 14, 15 inside the pump body .
- a pusher 29 is generally fixed at the first end of the actuating rod.
- the pump also comprises a return spring 9, which works in compression and which is mounted between the actuating rod 12, 7 and the piston 6, by urging the actuating rod 12, 7 towards the open end 4a of the pump body, and by biasing the piston 6 towards the inlet end 4b of the pump body.
- the pump body has a stop 24, which limits the movement of the piston 6 towards the inlet end 4b.
- the device comprises an abutment member 10 of annular shape, which is traversed axially by the actuating rod 12, 7, and which limits the movement of said actuating rod 12, 7 towards the open end 4a of the reservoir, by abutment of an external shoulder 7a of the actuating rod against said abutment member 10.
- the abutment member 10 comprises an elastic flange 21 which is flared towards the open end 2 of the reservoir, and which, when 'it is not deformed, has an external diameter slightly greater than the internal diameter of the reservoir.
- the stop member 10 is forced into the tank 1, until the crown 21 reaches the level of the hollow sectors 17, in which it expands by producing a very solid snap-fit.
- the stop member thus defines a rest position of the actuating rod 12, 7.
- the piston 6 obscures the lateral orifice 14, 15 of the outlet duct 13 , and only the guide rod 12c of the second end 12b of the actuating rod enters the intake duct 8, without closing said intake duct in a sealed manner.
- the pump body 4, the piston 6 and the actuating rod 12, 7 define a pump chamber 11, which, when the actuating rod 12, 7 is in its rest position, communicates with the reservoir 1 via the dip tube 28.
- the contents of the chamber are compressed, so that the piston 6 rises in the pump body in the direction of the open end 4a, at the same time as the actuating rod descends in the direction of the end of entry 4b.
- the piston 6 clears the lateral orifice 14, 15 of the outlet conduit which communicates with the pump chamber 1 1, which allows the emission of the dose of fluid substance contained in the pump chamber 11.
- the piston 6 comes to bear against the stop 24 and the actuating rod is again moved towards the open end 4a of the pump body under the action of the return spring 9, which firstly has the effect that the piston 6 again obscures the lateral orifice 14, 15, which isolates the pump chamber 11, and that a vacuum is created in the chamber pump 11.
- the actuating rod 7, 12 returns to its rest position, the part 12d of the second end 12b. of the actuating rod emerges from the sealing lip 8a so that the pump chamber 11 communicates again with the reservoir 1 via the dip tube 28.
- the pump chamber 11 is then filled with a new dose of fluid substance.
- the pump body has an external axial groove 23 which communicates the interior of the reservoir with said annular air intake passage 22 when the actuating rod is not in its rest position.
- the abutment of the shoulder 7a of said actuating rod against the burea member 10 forms a sealed contact which cuts the communication between the return air passage 22 and the groove 23.
- the stop member 10 comprises an outer annular sealing lip 30 which is in sealed peripheral contact with the surface 20 of the side wall of the reservoir.
- the actuating rod 7, 12 has two separate parts, namely an outer sleeve 7 which slides with sealing inside the piston 6, which is biased by the return spring 9 and which has the shoulder 7a which abuts against the abutment member 10.
- the external sleeve 7 is traversed axially by a central channel 16.
- the external sleeve 7 further comprises a lateral orifice 15 which opens radially inside the central channel 16.
- the end sleeve 7 advantageously comprises an internal sealing lip 31, at the axial end of the external sleeve 7 which is closest to the inlet end 4b of the pump body.
- the actuating rod further comprises an internal rod 12, which has the first and second ends 12a and 12b of the actuating rod as well as the blind outlet channel 13 which opens radially outside the rod 13 through an orifice 14.
- the internal rod 13 can be mounted in the external sleeve 7, the seal between the external rod 13 and the sleeve 7 being ensured by the sealing lip 31.
- the orifices 14 and 15 communicate and together constitute said orifice of the actuating rod.
- the internal rod 12 is snapped inside the external sleeve 7, for example by means of an annular external rib 32 of the internal rod 13, and a corresponding groove 33 formed inside the central channel 16 of the external sleeve 7.
- the rod 13 has, at its lateral orifice 14, an external diameter less than the internal diameter of the central channel 16, so that the orifices 14 and 15 communicate together whatever the respective angular orientation of the outer sleeve 7 and inner rod 12.
- the pump body 4 When the device is assembled before filling, the pump body 4 is first fitted inside the tank 1, as far as it stops against the shoulder 3.
- the shoulder 3 could be deleted here, the positioning of the pump body 4 being obtained simply by the stop of the dip tube 28 against the bottom lb of the tank, on the dip tube 28 has sufficient rigidity.
- the piston 6 then the spring 9 and the external sleeve 7, then the stop member 10 is forced into the reservoir 1, until the elastic collar 21 of the stop member 10 snaps into the recessed sectors 17 formed inside the side wall of the tank 1.
- the device can then be stored and transported in this state, the internal rod 12 being delivered separately, possibly assembled with a pusher 29.
- an injection tube 34 of said fluid substance is engaged, inside the member stop 10.
- Said injection tube 34 has an external diameter such that it penetrates without sealing in the center of the stop member 10 but abuts against an inner shoulder 7b of the outer machon 7, so that it pushes said sleeve external 7 towards inlet end 4b of the pump body.
- the air contained in the reservoir 1 is expelled via the axial groove 23 and a space 35 left free between the stop member 10 and the injection tube 34.
- the injection tube 34 is removed, then the internal rod 21 is fixed to the external sleeve 7 by a simple axial fitting passing through the stop member 10.

- the references already used in FIGS. 1 to 7 designate identical or similar elements.
- FIG. 8 represents a second embodiment of the invention, which differs from the first embodiment in that the return spring 9 is not mounted between the outer sleeve 7 and the piston 6, but between the bodies pump 4 and the piston 6, so as to urge the piston 6 towards the open end 4a of the pump body.
- a second spring 26, of greater stiffness than the first spring 9 is mounted between the piston 6 and the outer sleeve 7, to urge the sleeve 7 towards the open end 4a of the pump body, and to simultaneously urge the piston 6 to a position where it obscures the outlet orifice 14, 15 of the actuating rod 7, 12.
- FIG. 9 shows a third embodiment of the invention, in which a support piece 36 in the form of a cup is fixed, for example, by force fitting or by other means, at the end of the external sleeve 7 which is closest to the inlet end 4a of the pump body .
- the return spring 9 is mounted between the support piece 36 and the pump body, and the pump also comprises a second spring 25, which is mounted between the external sleeve 7 and the piston 6, to urge the piston 6 towards a piston where it obscures the lateral orifice 14, 15 of the actuating rod 7, 12.
- This pump operates on a principle similar to that of the pump described in document EP-A-0 486 378 (see in particular FIG. 7b of this document), with an inlet valve such as that described in documents FR-A-2 305 241 and FR-A-2 314 772.
- the second spring 25 could be omitted.
- FIG. 10 represents a fourth embodiment, which differs from the first embodiment in that the pump body does not have an external axial groove for the intake of air, and said pump body is fitted with sealing in the reservoir 1.
- the pump body 4 does not have a dip tube 28, the bottom lb of the reservoir has a vent orifice 37, and a piston 38, of shape substantially complementary to the shape of the inlet end 4a of the pump body, is mounted sliding with sealing inside the side wall 1a of the reservoir 1.

- the piston 38 may include a stud 39, which fits with a slight friction in the intake duct 8 of the pump body during assembly of the device in order to hold the piston 38 in the vicinity of the inlet end 4b of the pump body before filling the reservoir.
- the filling of the tank is preferably carried out under vacuum.
- FIG. 11 represents a fifth embodiment of the invention, which is close to the fourth embodiment but which however differs from the fourth embodiment in that the reservoir 1 does not include a piston 38, but a flexible bag 39 is fixed to the inlet end 4b of the pump body.
- Said flexible bag 39 contains said fluid substance and communicates with the intake duct 8 of the pump body.
- the flexible bag 39 has an open end 39a on which is molded a fixing ring 40, which is fitted with sealing at the inlet end 4b of the pump body.
