Definitions

  • the present invention relates to a dispensing head of a product intended for the actuation of a dispenser member mounted on a container, in particular of a valve mounted on a pressurized container, and the distribution of a product contained in the container.
  • the invention relates to a head of distribution allowing the distribution of the product according to at least two flow rates different.
  • the dispensing head described in US Pat. No. 3,363,968 uses a hoop attached to the container and a push-button that moves axially for actuate a valve stem, the push button being movable in rotation by relative to the band between two distribution positions according to two flow rates different.
  • the push button is traversed transversely by a duct that ends at both ends by section openings different.
  • the duct is intended, when pushing the pushbutton, to be placed next to a channel, formed in the band, which opens through an orifice of distribution.
  • the user angularly positions the pushbutton by relative to the hoop so that one or the other of the openings of the duct can come next to the canal in order to distribute the product according to the selected flow by pressing the push-button.
  • the dispensing head described in US Pat. No. 3,703,994 uses a hoop axially movable relative to the container in response to the depression of a push-button surmounting the hoop and intended to actuate a valve.
  • the push button is also mobile in rotation with respect to the ferrule between three distribution positions according to three different flow rates.
  • the fret includes a axial duct which communicates with the interior of the container, when the valve is actuated, and which opens laterally through three section openings different, each opening opening above a plot still called "centerpost".
  • the push button has a spray nozzle which, in each distribution position, comes next to a centerpost.
  • a complementary shaped conduit, integral with the pushbutton, is inserted in the duct of the fret.
  • the push-button conduit includes a slot axial, which in each distribution position of the push button, comes into look at one of the openings.
  • the necessary clearance between the nozzle and each centerpost to rotate the push-button between the three positions only allows not correctly position the nozzle next to each centerpost of so we hardly get a good spray.
  • such a game does not allow not to position identically the nozzle opposite the different centerposts so it's very difficult to get a reproducible spray of a position to another.
  • the conduit connecting the valve to the nozzle defines a relatively large volume so that after the user has released the push button, all the remaining product in this volume is distributed.
  • US 2,887,273 also discloses a dispensing head having a diffuser attached to the container and the valve stem and a push-button designed to actuate the valve stem.
  • the push button is mobile in rotation with respect to the diffuser between two distribution positions according to two different flows.
  • the diffuser has two holes of different section spray, diametrically opposed, and push-button has an opening in its wall intended to be placed opposite from one or the other of the spray orifices.
  • the push button is opposite one of the orifices, the other orifice is obscured by a wall of the push button. According to this configuration, it is necessary to make two spray holes which complicates the realization of the head since such holes are more complicated to realize than simple opening.
  • passage of different section we mean passages that lead to openings whose surface is different.
  • Diameter of the dispensing orifice means the diameter of the circle when the orifice is circular, or the diameter of the circle circumscribes to the section of the orifice when it has a different shape than a circle.
  • the presence of the elastically deformable connecting means makes it possible to make a conduit by a molding process from a single piece with fixing means, which can move relative to the means of fixation. Such a piece is simple to make and is inexpensive.
  • the dispensing head is easy to perform and inexpensive given that only one spray orifice formed in the means of operation and that the two passages of different section are easily feasible since they can be formed during the molding of the conduit.
  • the connecting means are elastically deformable, so that they resume their initial position when the constraint that deforms them stops.
  • the fixing means are mounted in a fixed manner axially on the container so that the head is properly kept on the container.
  • the connecting means allow a displacement of the conduit in response to actuation of the actuating means.
  • connection means are constituted by a wall transverse to the X axis, which is undulating. This configuration of the wall allows it to easily deform and return easily to its position initial.
  • the duct is formed along the X axis and has a first end on which are fitted with the actuating means and a second end able to cooperate with the dispensing member.
  • the conduit transmits directly the pressure exerted on the actuating means to the organ of distribution.
  • the passages may be slots extending parallel to the X axis which are of different width that are angularly spaced. It is obvious that any other form of passage can be used. Ways actuators are then rotatable about the X axis between first and second positions.
  • the dispensing head can be configured so as to authorize the actuation of the dispensing member only when the means in the first and second positions.
  • the head of distribution may comprise an axial abutment against which the means when they are not in one or the other first and second positions so as to prevent the actuation of the distribution organ.
  • the dispensing head may comprise at least two radial stops limiting the rotational movement of the actuating means.
  • the dispensing head may comprise means sound identification to signal positioning in one or the other first and second positions.
  • the means of sound identification can be formed by the cooperation of a first relief formed on the means actuation and a second integral relief of the conduit, the first relief being adapted, during the displacement of the actuating means with respect to the duct, to come in contact with the second relief and to cross it by deforming it resiliently so as to produce a sound signal.
  • the dispensing head may also comprise means of identification visual to identify the first and second positions.
  • the container may be pressurized and the dispensing member may be a valve male comprising a valve stem on which the conduit is fitted, or well a female valve, that is to say without valve stem, in which is Veronica leads him.
  • the container is pressurized atmospheric and is equipped with a pump.
  • the invention is particularly useful for packaging and dispensing a cosmetic or care product, especially a hair product.
  • FIGS. 1 to 7 The packaging and dispensing assembly illustrated in FIGS. 1 to 7 is formed of a pressurized container 30, shown partially in the figures 2, 4, 5 and 7 on which is fixed a dispensing head 1 according to the invention which can be closed by a hood 40.
  • the container 30 is formed by a pressurized can of X axis, formed by a body cylindrical 31 of revolution, whose upper end is closed by a cup 32 crimped on a rolled edge 33 of the container.
  • the cup 32 is provided valve 34 which has a hollow valve stem and which can be actuated for example by depressing the valve stem. It is obvious that one can alternatively use a valve that can be operated by tilting of the valve stem.
  • the container 30 may contain a product to be sprayed, for example a product cosmetics, and a propellant, which may or may not be stored under a liquefied form in the container 30 and whether or not delivered with the product.
  • the product then comes out as a spray, that is to say in the form of fines particles in suspension either in the gas or in the air.
  • the dispensing head 1 is also of X axis and is formed of two parts moving relative to each other between two positions each allowing the distribution of the product at a different rate.
  • the first part of the head is constituted by a hoop 10 for protecting the valve stem and intended for be attached to the container.
  • the second part consists of a push button 20, allowing the actuation of the valve and which is rotatable compared to the fret.
  • Each of the two pieces is obtained by molding a thermoplastic material from a single piece.
  • the hoop 10 comprises a fastening skirt 11 for fixing the head on the container.
  • the fixing skirt 11 is provided with an annular bead 110 on its wall interior allowing to fix it on the container by snapping under the edge rolled 33 of the container and the cup 32.
  • the attachment skirt 11 has a radial recess 111 towards the inside of the skirt and extends axially above the recess to an upper end from which is formed a transverse wall 12.
  • the free edge 130 is provided to abut against the container in the mounted position of the hoop on the container, as seen on FIGS. 4, 5 and 7. The fins 13 thus make it possible to limit the sink axial of the hoop when snapped onto the container.
  • the transverse wall 12 is a thin wall which has a corrugation so it is elastically deformable which allows it to deform when the axially solicits.
  • the wall 12 is traversed at its center by a conduit 14 formed in the X axis.
  • the duct 14 extends on either side of the transverse wall 12 from a open lower end 14a which is engaged on the valve stem 35, up to an upper end 14b, also open, on which comes to slip an axial skirt 23 of the push-button.
  • An annular groove 14c is provided on the outer surface of the conduit 14 to receive a cord annular 23a provided on the inner surface of the axial skirt 23 of the pushbutton to ensure the axial retention of the push button on the hoop.
  • the cooperation of the annular bead 23a with the annular groove 14c ensures a seal between the duct and the inside of the push-button.
  • the conduit 14 is of cylindrical shape of revolution and defines in its part lower a shoulder housing in which can engage so substantially sealing the upper part of the valve stem 35 which the upper end 35a abuts against the shoulder of the housing.
  • the lower end 14a of the duct flares slightly to facilitate the setting in place of the conduit on the valve stem.
  • the upper end 14b comprises two axial slots 15a and 15b of different width which define two passages for the product of different section to bring out the produced according to two different flow rates. It is obvious that we can foresee as many slots of different width that we want to obtain flow rates different. According to the particular example shown, the two slots 15a and 15b are angularly spaced about 80 °.
  • the upper end 14b of the conduit comprises a first passage 15a formed by a slot opening on an opening of larger section.
  • the upper end 14b comprises also a second passage 15b for the product, longer than the first and which ends with a second opening in the form of a smaller groove section as the opening of the first pass.
  • This groove connects to the first slot by a recess 60 formed at the upper end of the According to this variant, the product coming from the conduit 14 is routed to the second opening by a portion of the first slot 15a and by the step 60.
  • the fastening skirt 11 connects at the recess 111, by a annular transverse wall 16, with an outer skirt 17, concentric with the skirt 11.
  • the outer skirt 17 is intended to form the extension of the container wall when the dispensing head is mounted on the container.
  • Two M marks are provided on the outer surface of this skirt 17 which visually indicate the angular positions of the two slots 15a and 15b.
  • a first mark M is for example the number "1" which corresponds to the position of the slot 15b of smaller width and therefore which allows a distribution at a low rate
  • a second mark M is for example the number "2" which corresponds to the position of the slot 15a of greater width and so that allows a distribution at a higher rate.
  • the skirt 17 has a shoulder 170 and extends axially above of this shoulder by an axial crown 171.
  • the crown 171 has an annular bead 172 on its outer wall for fixing of the closure cap 40 by snapping into an annular groove 410 present on the inner surface of the side wall 41 of the hood.
  • the side wall 41 of the hood constitutes the extension of the outer skirt 17 and the free edge 411 of the hood is in abutment against the shoulder 170.
  • the annular transverse wall 16 of the hoop is crossed by two openings in an arc 18 and 19, diametrically opposite on the wall annular cross-section, formed near the outer skirt 17, and in which are intended to move two legs of the push button, as will be seen in detail later.
  • the first opening 18 is formed on the side of the axial slots 15a and 15b of the duct and the second opening 19 is formed at the rear of the axial slots 15a and 15b.
  • the second opening in an arc 19 ends, near each end of the arc, by two opening portions 19a and 19b which radially inwardly extend aperture 19.
  • Opening portions 19a and 19b are angularly spaced about 80 ° and are each formed respectively according to the diameter passing through each of the slots axial 15a and 15b.
  • the portion 160 of the annular transverse wall 16 located between each opening portion 19a and 19b serves as an axial stop for the push button as we will see in detail later.
  • Two stops vertical lines 190a and 190b respectively border each outer edge of each opening portion 19a and 19b.
  • the stops 190a and 190b extend axially from the annular transverse wall 16 to a free edge higher, and extend radially from the outer surface of the skirt of fastening 11 to the slot 19.
  • the stops 190a and 190b are relatively rigid because they are integral with both the transverse annular wall 16 and the fixing skirt 11, and thus make it possible to limit the movement of rotation of the push button.
  • Two radial tabs 191a and 191b extend axially from the annular transverse wall 16 to a free edge higher 191a 'and 191b'. They are formed on the side of the inner edge of each opening portion 19a and 19b.
  • the tabs 191a and 191b extend, at an axial height less than that of stops 190a and 190b and are also narrower than the stops 190a and 190b.
  • the tabs 191a and 191b do not extend to the opening in an arc 19 and are formed remote from the fixing skirt 11 so that they are elastically deformable.
  • the tabs 191a and 191b cooperate with the pushbutton in order to constitute a means of sound identification to indicate the transition to the use position.
  • the dispensing head comprises a push button 20 which has an upper wall 21, intended to serve as a support for a finger of the user.
  • the upper wall 21 connects peripherally to a first skirt 22, of diameter less than the diameter of the outer skirt 17 of the hoop.
  • the push-button 20 comprises, inside the first skirt 22, a second skirt 23, cylindrical of revolution.
  • the skirt 23 is of axis X and comes to slip on the upper end 14b of the conduit 14 around which it is mobile in rotation.
  • the second end 24b opens into a nozzle holder.
  • the nozzle holder comprises a stud 25, or "centerpost" on which can be fixed a nozzle to vortex channels 50 conventional.
  • the nozzle 50 defines an orifice of distribution 51.
  • An arrow F is provided on the upper wall 21 to indicate the position angle of the end 24a of the channel 24, so that when it is put into look at either mark M on the hoop, this indicates visually to the user the two positions in which he can operate the push button to distribute the product.
  • An X axis tip 26 is formed inside the second skirt 23 and comes insert inside the conduit 14 when the pushbutton is mounted on the fret.
  • the tip 26 has a diameter slightly smaller than that of the conduit of to form an annular passage for the product inside the conduit.
  • the tip 26 makes it possible to limit the dead volume inside the duct and thus limit the pressure losses inside the duct in order to optimize the flow with which the product comes out.
  • the volume of product that can contain the dispensing head between the valve 34 and the dispensing orifice 51 by decreasing the dead volume, the volume of product that can contain the dispensing head between the valve 34 and the dispensing orifice 51.
  • the spraying of the product through the orifice of distribution stops substantially at the moment the user releases the pushbutton, that is to say as soon as the valve is no longer open since the quantity of product remaining inside the head is relatively small.
  • the peripheral skirt 22 of the push button extends axially, in its lower part, on two diametrically opposite angular portions, by two legs 27 and 28, each intended to move respectively in the arcuate openings 18 and 19 provided in the hoop.
  • Each leg 27 and 28 is provided at its lower end with a hook 270 and 280 which comes abutting under the annular transverse wall 16, when the legs pass through openings 27 and 28. Hooks 270 and 280 serve to maintain axially the push-button on the hoop.
  • the tab 27, located on the side of the dispensing orifice 51, is provided to move in the arcuate opening 18.
  • the tab 28 is provided to move in the arched opening
  • the tab 28 comprises a rib 281 whose axial length and the radial length are sufficient to abut against each stop 190a and 190b during the rotational movement of the push button on the hoop.
  • the rib 281 has a shoulder 281a in its lower part which allows to move away from the vertical edge of the tabs 191a and 191b.
  • the shoulder 280a comes into contact with the upper free edges 191a 'and 191b' of each tab 191a and 191b and passes through them elastically deforming, as seen in Figure 6, so as to produce a sound signal.
  • the duct 14 closes the end 24a of the channel 24 so as to prevent any communication between the outlet orifice 51 and the inside of the distribution duct 24.
  • the tab 28 passes through the slot 19 and is between the two openings 19a and 19b.
  • the lower end of the rib 281 formed on the push button is in axial abutment against the portion 160 of the transverse wall annular 16 so that if the user presses the push button 20, this one can not sink and therefore can not operate the valve 34.
  • the user rotates the pushbutton 20 around of the X axis so as to position the arrow F in front of one of the marks M. If he wants to spray the product at a relatively high rate, he chooses the mark "2" so that the slot 15a is positioned opposite the end 24a of the channel 24.
  • the leg 27 moves in the opening in an arc 18 and the leg 28 moves in the opening in an arc 19 until the shoulder 281a of the rib 281 comes against the tongue 191a and, because of its elasticity, the crosses to abut against the stop 190a by emitting a signal sound allowing the user to know that the push button is placed in a distribution position.
  • the rib 281 is located above the opening 19a and the dispensing orifice 51 communicates with the interior of the conduit 14, via the slot 15a.
  • the user can then operate the valve by pressing the push button as shown in Figure 6.
  • the rib 281 of the tab 28 sinks into the opening portion 19a then that the tab 27 remains attached to the transverse wall 16 thanks to the hook 270.
  • the skirt 23 then moves in a movement having a component axial and radial driving in its movement the conduit 14, on which it is fitted, the movement of the duct being possible thanks to the fact that the wall 12 is deformed.
  • the lower end 14a of the duct exerts in turn a pressure on the valve stem 35 which sinks in order to actuate the valve 34.
  • the product contained in the container then leaves the container by the channel inside the valve stem and arrives at the dispensing orifice 51 in passing through the conduit 14 and the channel 24.
  • valve stem rises and the dispensing of the product stops.
  • the user no longer wishes to spray product he turns the pushbutton in order to position it between the two distribution positions before repositioning the closure cap 40.
