Definitions

  • the invention relates to a precompression pump for spraying under pressure of a liquid, and in particular of a cosmetic product such as a lacquer capillary.
  • the invention aims, in particular, to provide a pump of this kind, manually operable and compact, so that it can be housed in the cover of a liquid dispenser cover.
  • a manual precompression pump comprising, among other things, a pumping of the liquid in communication with a precompression chamber, a spray nozzle connected by a distribution channel to the precompression, and a supply channel fitted with a non-return valve opening into the pumping chamber.
  • the precompression pump of the kind described in EP-A 0 437 131 deserves to be improved from the point of view of spraying accuracy, because that this pump is actuated by pressing a push button which also includes the spray nozzle. As a result, the place where the spray is to be applied, is difficult to target.
  • this known pump is difficult to assemble.
  • all the constituent parts of this pump are aligned on the same axis of symmetry, its bulk in the axial direction is relatively large, which prohibits its use in many realizations using a covering hood.
  • This pump has the disadvantage of containing a number of constituents Student. In addition, it is difficult to assemble industrially. The price of returns from such a pump is therefore relatively high.
  • the link between the pumping chamber and the precompression chamber is constituted by a relatively long duct with several angles. As a result, there is a pressure drop in liquid pressure during dispensing, resulting in a poor spray quality;
  • a one-way valve is provided in this conduit, which further increases the pressure drop, thus requiring considerable effort for the user to operate this pump.
  • this pump has a large size; because of this its use cannot be envisaged for all needs, in particular for the distribution of liquids contained in containers of small capacity.
  • the present invention aims to remedy the drawbacks of the prior art, by providing the user with a dispensing assembly for a simple construction, with a fixed dispensing head and a pump with precompression, small dimensions and a reduced number of parts, and which therefore, from an industrial point of view, is easy to assemble.
  • the pressure drop has been minimized compared to pumps according to EP-A 0 437 131 and FR-A-2 634 825, so that the spray quality is improved. It this results in a reduction in the particle size of the liquid leaving the nozzle.
  • the present invention relates to a pump precompression for spraying under constant pressure of a liquid, kind of that described by FR-A-2 634 825 not including a valve between the pumping chamber and compression chamber. It is characterized in that that the precompression chamber is an extension of the pumping, and that the liquid contained in the pumping chamber reaches directly to the precompression chamber, upon actuation of the means of maneuver.
  • a means can be provided causing the evacuation of air inside the pump body, disposed between the first and second pistons.
  • this means is a central pin provided on the upper surface of the second piston, facing the pumping chamber; this pin is able to bear against the first piston, when the operating member is actuated, that is to say, when the volume of the pumping chamber is at a minimum.
  • a connection mechanical is established between the two pistons, the first pushing the second in a position such that compressed air in the pump body can escape through the distribution channel.
  • the nozzle is fixed by relative to the pump body.
  • This spray nozzle is provided with a oriented spraying, along an axis substantially orthogonal to the axis of symmetry which defines the precompression chamber.
  • the sliding means of communication and closing of this pump is constituted, according to a first embodiment, by a first annular lip, integral with the second piston. In the rest position of the pump, this lip therefore closes the communication between the precompression and the distribution channel.
  • the pump is actuated, by driving the operating member against the first return means elastic, the pressure of the liquid that is inside the pump body, will go up to a predetermined value and cause this communication, by pushing the precompression member against the second return means elastic. It is clear that the predetermined precompression value depends on the force developed by this second elastic return means.
  • a means of bringing it to atmospheric pressure can be provided, consisting, for example, of an air intake orifice pierced in the wall of the body pump, opening into the lower part of the precompression chamber, that is to say in the part where the second elastic return means is arranged, to balance the pressure in the tank with the external pressure.
  • a sealing means can be disposed between the air intake opening and the tank, closing this opening periodically capable of admitting a dose of air into the tank during the distribution of a respective dose of liquid.
  • an orifice is provided between the precompression chamber and the tank.
  • this central orifice is extended by a cylindrical extension crossed by a capillary channel.
  • the capillary channel has the function of preventing liquid from the tank entering the lower part of the chamber precompression, on the side of the second return means. This provision is all the more useful, since the liquid to be dispensed is a composition capable of dry or seal the precompression piston, such as, for example, a hair spray or paint.
  • this sealing means can be a second annular lip carried by the precompression piston which is arranged inside the precompression chamber. This second lip is placed at a level located between the first lip and the reservoir.
  • the precompression is provided with at least one longitudinal rib, located in a area between the second sealing lip, when it is in the rest position, and a bottom, which separates the precompression chamber from the tank. So when actuation of the pump, the second sealing lip of the piston precompression is moved away from the inner wall of the chamber precompression, and air from the air intake port can enter, via the orifice between the bottom of the precompression chamber and the tank, in order to replace with air, an equivalent volume of a dose of liquid dispensed.
  • the means for setting the atmospheric pressure can be constituted by a chimney carried by the piston precompression and extending it towards the tank and crossing a communication in the bottom of the precompression chamber.
  • the end of the chimney emerging in the tank is provided with a flared cylindrical rod, with a larger diameter than that of the communication.
  • this ring is able to close the communication between the tank and the lower part of the precompression chamber, on the side of the second reminder.
  • the sliding setting means in communication and closing the pump can be constituted by a pin formed at one end of the second piston which is opposite the first piston. This pin is able to seal an extension of the distribution channel parallel to the axis defining the precompression chamber.
  • the first elastic return means housed in the chamber pumping, is constituted by a helical spring, preferably made of metal.
  • the second elastic return means is also constituted by a spring metallic helical. As explained above, by choosing a spring more or less hard, we can influence the force necessary to trigger the liquid distribution.
  • the non-return valve which prevents the liquid accumulated in the chamber from pumping back down into the tank, is preferably made up of a spherical ball housed in a frustoconical portion of the supply channel. By via a dip tube this channel communicates with the contained liquid in a tank.
  • This pump can be used for spraying many liquids, such as, for example a cosmetic composition, in particular a hairspray, a body deodorant, dermatological lotion, or composition pharmaceutical etc.
  • a cosmetic composition in particular a hairspray, a body deodorant, dermatological lotion, or composition pharmaceutical
  • the invention also relates to a liquid distribution assembly, under form of droplets, comprising the reservoir for the liquid to be dispensed, surmounted by a precompression pump conforming to the characteristics which have just been described.
  • This fixing means comprises, for example, a disc-shaped element, extending radially to the pump body and comprising a peripheral part shaped like a cylindrical skirt, provided with the inside of a snap bead, capable of cooperating with an annular groove complementary, carried out on a neck with which the tank is provided.
  • the reservoir may, in addition, include a covering hood, fixed to the tank; this hood surrounding the pump mounted on this tank.
  • the pump operation is actuated by means of a lever arm, articulated on a wall of the covering hood.
  • This arrangement allows the user spray the liquid in good conditions so that specifies, while making, upon actuation, a lower effort than that necessary for the prior art pump
  • a precompression pump 1 for spraying a liquid, such as a lacquer capillary, contained in a reservoir 24, surmounted by a cylindrical neck 25 provided an external snap bead 26.
  • a liquid such as a lacquer capillary
  • the pump 1 comprises a body 3, generally cylindrical, intended to be fixed on the neck 25 of the tank.
  • the fixing is carried out by a snap ring 16, consisting of a cylindrical skirt 16a, carrying on the inside a rib annular 16b, able to cooperate with the bead 26 of the neck.
  • the skirt 16a is connects to the periphery of a disc-shaped element 16d, itself extending radially from the pump body 3.
  • This disc-shaped element 16d comprises, on the side facing the reservoir, a sealing skirt 16c, applying in the opening of the neck 25 of the reservoir 24.
  • the pump body 3 forms, at its end remote from the reservoir, a chamber pump 2 cylindrical having a central axis X of revolution, chamber in which is housed a helical compression spring 9, generally metallic, which is in abutment against a first piston 7.
  • This piston 7 is connected to a member maneuver 6, cylindrical, having an emerging end 6a used to actuation of the pump.
  • this piston 7 On the side facing the tank, this piston 7 has an extension 6b inserted inside the turns of the spring 9.
  • the piston 7 also has two lips sealing rings applying against the internal wall of the body 3, lips of which a first 7a is turned on the side of the emerging end 6a, while the second 7b is turned in the opposite direction.
  • a fixing cup 8 comprising a snap bead 8c inside, this bead cooperating with an annular bulge 3a which is provided the free end 3b of the body 3.
  • the cup 8 has, on its side facing the tank, a cylindrical skirt 8a, used for sliding guide of the member operation 6.
  • the pump body 3 is connected in its central region, to an extension cylindrical 17 of revolution about an axis Z substantially perpendicular to the central axis X, this extension constituting a distribution element.
  • the element distribution 17 comprises an annular recess 17a, which leads to a channel distribution 18 parallel to the Z axis, this channel leading to a precompression 5 having an axis of revolution Y.
  • the axis Y is parallel to the axis X and orthogonal to the Z axis.
  • the annular recess 17a defines a central stud 19, on the end 19a of which is fixed a spray nozzle 20, provided with a central orifice 21.
  • the pumping chamber 2 On the side facing the tank, the pumping chamber 2 is extended by two cylindrical bores, of reduced diameter compared to the diameter of the chamber pump 2, of which a first bore forms a supply channel 4, and of which the second forms the precompression chamber 5 which is delimited by a wall cylindrical 5b.
  • the distribution channel 18 communicates with the precompression chamber 5.
  • the wall 5b of the precompression chamber is provided with an air intake orifice 5a, the role of which will be explained later, during the description of the operation of the pump.
  • the bottom 5d has a cylindrical extension 23, crossed by a channel capillary 23a.
  • the cylindrical wall 5b is provided, inside the chamber 5, of one or more longitudinal ribs 5c (FIG. 1b), the role of which will be explained later.
  • the precompression chamber 5 comprises a precompression piston 10, of generally elongated cylindrical shape, capable of sliding tightly in this chamber, and which is provided with two annular projections, a first 10b comprising a sealing lip 10a, and a second 10g, provided with a sealing lip 10th, located at a level lower than that of the lip 10a, relative to the reservoir 24.
  • the two lips have a free edge which is directed on the same side, towards the pumping chamber 2.
  • the lip 10a constitutes a sliding means for placing in communication and closing F, able to close the distribution channel 18, in rest position, and to establish communication, in the distribution position of the liquid, between chamber 5 and channel 18.
  • the lip 10e constitutes a means between the outside and the tank.
  • the lower part 10c, facing the reservoir, of the precompression piston 10, is engaged in the turns of a second helical spring 11, constituting a second elastic return means, which has the function of pushing, in position rest, the precompression member 10 in a position, where the lip seal 10a is opposite the distribution channel 18, closing this one.
  • the lip 10a In this closed position, the lip 10a is in abutment against a annular bead 22, carried by the wall of the junction zone between the chamber precompression 5 and the pumping chamber 2.
  • the spring 11 is in abutment against the annular projection 10g carried by the precompression piston.
  • the precompression member 10 on the side facing the pumping chamber 2, forms a plate 10f which carries a central pin 10d extending in the chamber pumping 2 and whose role will be explained later.
  • the supply channel 4 has an axis of symmetry W, and is connected, on its side opposite to the pumping chamber 2, to a conical restriction zone 4a, offering a passage 14 to the liquid contained in the reservoir 24, via a dip tube 13.
  • the W axis is parallel to the X and Y axes, and orthogonal to the Z axis. It is interesting to note that the axes W, X, Y and Z lie in the same plane (that of figure 1).
  • a ball 15 having an intermediate diameter between that of the supply channel and that of the restriction zone 4a.
  • This ball 15 serves as a liquid admission valve, preventing the liquid sucked into the pump body from falling back into the tank 24.
  • the operation of the precompression pump 1 according to the invention is the following: at rest, the pump is in the position shown in Figure 1, the body 3 containing air, and the liquid are in the reservoir 24.
  • the user must first prime the pump, i.e. ensure the filling the body 3 with liquid, this operation expelling air. For this, he must press the actuator once or twice 6. During this operation, the air enclosed in the body 3 is compressed. In the low position, the surface 6b of the operating member 6 bears against the pin 10d of the second piston 10, from which it results in a descent thereof, thereby freeing the passage 18 through which the air tablet may escape.
  • the spring 9 causes the piston to rise 7.
  • a vacuum is created in the body 3, which also causes the opening of the non-return valve, that is to say a displacement of the ball 15, and the ascent of a certain amount of liquid in the body 3.
  • depression of the piston 7 causes a rapid increase in pressure in the body 3.
  • the precompression member 10 moves, the lip 10a thus releasing the distribution channel 18.
  • This channel brings the liquid into the annular recess 17a which is in communication with the spray orifice 21, where occurs, thanks to the short distance to be traveled in the distribution channel 18, a spraying good quality liquid.
  • the orifice 5a opening to the outside can be put in communication with the reservoir 24 via the precompression chamber and the capillary channel 23a.
  • rest position which corresponds to the high position of the precompression piston 10
  • no communication is possible, that is to say that the precompression 5 does not communicate with the distribution channel 18, due to the presence of the lip 10a, and the air intake orifice 5c does not communicate with the reservoir 24, because the lip 10e seals.
  • the piston of precompression 10 descends following actuation of the operating member 6, the lip 10e slides in an area, where the ribs 5c are arranged. These ribs then cause the seal between the 10th lip and the wall to break interior of chamber 5, and air from port 5a can enter the tank 24, thus putting it at atmospheric pressure.
  • FIG. 2 there is shown a second embodiment of a precompression pump according to the invention.
  • the coins constitutive bear the reference numbers of analogous pieces or playing a role similar to those in Figure 1, increased by 100.
  • the description of provisions identical to those of FIG. 1 will not be repeated.
  • the pump body 103 does not include means for setting atmospheric pressure, but it is possible to use a means similar to those described with reference to Figures 1, 4 and 5.
  • the precompression member comprises a piston 110, the end of which 110b turned towards pumping chamber 102, has a shutter pin 110a which closes, in the rest position, an orifice 118c, formed in an extension angled 118b of the distribution channel 118.
  • the piston 110 is mounted on a spring 111 which ensures, in the rest position, the closure of the setting means communication and closing F.
  • the installation of the spring 111 is ensured by a capsule 127 slammed at the bottom of the precompression chamber 105.
  • FIG. 3 there is shown a partial section of a distribution assembly 200 according to the invention, equipped with a precompression pump 201, in accordance with realization of figure 1.
  • the constituent parts of this set, when they are identical to those in FIG. 1 have the same reference numbers, plus 200. So we see a precompression pump 201 mounted by snapping onto the neck of a reservoir 224. On a peripheral projection 232 of the tank a covering hood 233 has been fixed, for example by breakdown, surrounding pump 201.
  • This covering hood 233 has a front face 234, in which there is cut out a light 229, through which the liquid spray cone can pass, during the distribution of the liquid.
  • the front face 234 of the cover 233 also includes an elastic bending zone 231, for example a film hinge, to which a lifting arm 230 is connected.
  • This lever arm is provided with a support zone 228 of rounded shape, intended to cooperate with the actuator 206 of the pump 201.
  • the use of the assembly 200 is as follows: when the user presses the lever 230, in the direction of arrow A, the depression of the latter causes the lowering of the operating member 206 and at the same time the lowering of the piston 210 towards the reservoir 224. Then, access to the distribution channel 218 is released and good quality spraying can be done with minimal effort for the user.

  • the means for setting the atmospheric pressure is constituted by a chimney 310c carried by the piston precompression 310 and extending it towards the tank; this chimney crosses a cylindrical passage (or communication) 323a practiced in the bottom 305d of the precompression chamber 305.
  • the chimney 310c has a smaller diameter than the precompression piston 310 thus defining a annular space to allow air entry.
  • the diameter of this chimney is also lower than that of the cylindrical passage 323a.
  • the end of the chimney, emerging in the tank, is provided with a flared cylindrical rod 310h with a larger diameter than that of the cylindrical passage 323a.
  • passage 323a has an orifice 323 of form complementary to the 310h rod and able to cooperate with it; these two pieces form a valve. Under the thrust of the second spring 311 on the piston of precompression, in the rest position, this ring therefore closes the communication between the tank and the precompression chamber 305.
  • the precompression piston 310 moves towards the tank, and thus move the rod 310h away from the cylindrical passage 323a, so that communication is established between the air intake opening 305a and the tank.
