    Description: The invention relates to a dispensing head for an aerosol container provided with a valve equipped with a valve stem, the dispensing head comprising a hoop, a push button movable in rotation with respect to the hoop around a hinge pin. rotation between a locked position and an unlocked position, a transfer conduit provided with a nozzle intended to cooperate with the stem of a valve when the dispensing head is mounted on an aerosol container provided with such a valve, and means blocking means being movable between a locking position in which the endpiece can not cooperate with the valve stem and an unlocking position in which the endpiece can cooperate with the valve stem to open the valve. In these dispensing heads, the push button can be moved relative to the hoop between a high position in which the tip of the transfer duct is remote from the valve stem and a low position in which the nozzle cooperates with the rod to open the valve.
    Such dispensing heads are commonly used in aerosol containers. When the push button is in the locked position, it is not possible by pressing it to move it downwards and to actuate the valve, because the blocking means prevent the push button from reaching the low position. On the other hand, when the push button is in the unlocked position, the blocking means no longer impede the downward movement of the push button: it is then possible to actuate the valve and to take the product contained in the container.
    WO 2007/022 422 discloses a dispensing head according to the preamble. The locking means are constituted by a plurality of radial ribs made inside the hoop and by an identical number of notches made in the lower edge of the push button. As long as the notches are not aligned with the ribs, the lower edge of the push button bears on the ribs and it is not possible to push the push button towards the valve to actuate it. By cons, when the notches are aligned with the ribs, it is possible to move the push button down and actuate the valve.
    Such a dispensing head requires only a few parts and is therefore well suited to mass use. However, the proposed solution has the disadvantage that the push button is retained in the upper position only by its periphery. It is therefore essential that its structure is sufficiently rigid so that its top wall can not deform towards the valve under the effect of the pressure of a finger while the push button is in the locked position. The object of the invention is to improve the distribution heads of the preamble to avoid the disadvantages mentioned.
    According to the invention, the locking means comprise a locking member pivotable between a locking position and an unlocking position, the locking member being provided with a bearing surface, which bearing surface is placed in the displacement stroke of the tip of the transfer duct in the valve stem direction when the locking member is in the locking position, and which bearing surface is outside the displacement path of the nozzle in the direction of the valve stem when the locking member is in the unlocking position. The locking means also comprise guiding means for putting the locking member in the locked position when the push button is in the locked position and putting the locking member in the unlocking position when the push button is in the unlocked position. The locking means of the invention have the advantage of interposing directly between the nozzle and the valve. Even if the top wall of the push button were to deform while the push button is in the locked position, it would have no consequence, because the tip would abut against the bearing surface of the locking means and could not come in contact with the valve.
    In a simple manner, the locking means may consist of a guide pin and a guide slot into which the free end of the guide pin penetrates, one of these two parts, preferably the guide pin , being fixed in the push button while the other, preferably the guide slot, is fixed on the locking member. Thus, when the push button pivots from one position to another, it carries with it the guide pin which in turn drives the locking member. Thanks to the slot, the connection between the pin and the locking member is not fixed. It is therefore not necessary that the locking member and the push button pivot about the same axis. The locking member is preferably constituted by a vertical wall having a notch, the upper edge of the vertical wall constituting the bearing surface. Thus, in the locking position, the portion surrounding the notch is in the stroke of the nozzle in the direction of the valve. By cons in unlocked position, the notch is aligned with the tip so that no obstacle is in its path towards the valve.
    It is preferable that the transfer duct be an integral part of the push button. The locking member may be fixed to the hoop by means of a hinge forming an axis of rotation parallel to the axis of rotation of the push button relative to the hoop. This hinge is preferably a film hinge. The hinge can be fixed to a fixing wall forming an integral part of the hoop.
    In order to facilitate the return of the pushbutton to the up position, it is preferable to provide disengagement means for disconnecting the tip of the stem of a valve when the button is moved from the unlocked position to the locked position.
    Similarly, stops may be provided on the hoop or on the push button which cooperate with a stop finger placed on the push button or on the hoop to limit the rotational movement of the push button relative to the hoop between the locked position and the unlocked position.
    Audible information means may be provided for transmitting one or more sounds, such as one or more clicks, when the pushbutton is moved from the locked position to the unlocked position or vice versa. The invention is described in more detail with the aid of the following figures:

    The dispensing head is composed of two main elements: a hoop (10) and a push button (20) housed movably on or in the hoop (10). The hoop and the push button have a certain symmetry of rotation about an axis of symmetry (A). The pushbutton (20) can rotate relative to the hoop about an axis of rotation coinciding with the axis of symmetry (A). Locking means (30) movable between a locking position and an unlocking position are provided to prevent actuation of the valve when in the locking position. Two embodiments are shown in the figures. The same references are used for both variants.
    The hoop (10) consists of two concentric annular rings (11, 12) interconnected by connecting walls (13) regularly distributed. The outer annular ring (11) is provided with fixing means for fixing the hoop (10) on the aerosol container, preferably at the junction between the housing and the cup of the valve. These fixing means are constituted by a bead (14) placed in the lower part of the inner wall of the outer ring (11). The inner ring (12) has first retaining means in the form of shoulders (121) regularly distributed in the upper part of its outer face.
    The push button (20) is composed of a cylindrical wall (21) closed at its upper end by a top wall (22). The push button includes a transfer conduit (23) for transferring the product to be sprayed from the outlet of the valve stem to the outside of the push button. The first end of this transfer conduit is provided with a nozzle (231) into which the valve stem penetrates when the push button is moved towards the valve in order to dispense the product to be sprayed. The other end (232) opens on the outer face of the push button, either at the cylindrical wall (21) for a jet close to the horizontal, or at the level of the top wall (22) for a jet close to the vertical. A nozzle may be provided at the end (232) of the transfer conduit opening on the outer face of the plug. The tip (231) is aligned with the axis of symmetry (A).
    The push button is provided with second retaining means intended to cooperate with the first retaining means (121) placed on the hoop (10). These second retaining means are constituted for example by shoulders (211) regularly distributed in the lower part on the inner face of the cylindrical wall (21). The lower face of the shoulders (121) of the hoop and / or the upper face of the shoulders (211) of the push button are preferably substantially horizontal (perpendicular to the axis of symmetry (A)), so that they can take support on each other to ensure the retention of the push button on the hoop. By against the lower face of the shoulders (121) of the hoop and / or the upper face of the shoulders (211) of the push button are preferably inclined so as to form ramps to facilitate the passage of the shoulders of the button behind those of the fret when mounting the push button on the hoop.
    The push button is provided with a support rib (24) oriented radially toward the center of the cylindrical portion (21). This support rib is placed below the second end (232) of the transfer conduit. It extends a sufficient distance so that its lower edge (241) abuts against the upper edge of the inner annular ring (12) of the hoop. At this point, the inner ring can be reinforced, as shown in Figures 6a and 6b by a bearing allowance (125). However, it is also possible to provide no extra thickness as in the embodiment of Figures 13a and 13b.
    When the push button (20) is mounted on the hoop (21), the shoulders (211) of the push button are placed below the shoulders (121) of the hoop so that the button can not come out. It can, however, pivot relative to the hoop around the axis of symmetry (A). When in the unlocked position, the button may swing about a horizontal tilt axis (B) passing through the point of contact between the lower edge (241) of the support rib (24) and the ridge upper of the inner ring (12) of the hoop. The tilting axis (B) is orthogonal to the general axis of symmetry (A). It is therefore possible to push the button towards the valve to lower the tip (231) towards the valve to actuate it. This tilting axis (B) is shown schematically in FIG.
    In order to limit the rotational movement of the push button (20) relative to the hoop (10), there is provided on the inner face of the inner ring (12) a locking stop (122) and an unlocking stop (123). ). Meanwhile, a finger (25) is placed inside the button so that at the end of the stroke, it comes into contact with one of the two stops (122, 123) of the hoop, limiting the rotational movement push button relative to the hoop between a locked position when the finger bears against the locking stop (122) and an unlocked position (123) in which it bears against the unlocking stop (123).
    Locking means (30) are provided in the dispensing head to prevent movement of the push button towards the valve when the locking means are in the locking position. These locking means are constituted by a locking member (31) fixed to the inner annular ring (12) via a vertical fixing wall (32). The locking member (31) is rotatable relative to the hoop about a vertical axis of rotation (C) parallel to the axis of symmetry (A). The axis of rotation (C) is constituted by a hinge, for example a film hinge. The locking member is in the present example in the form of a vertical wall curved in an arc so as to form a notch (311) in front of its concave face. The locking member (31) can be moved between a locking position visible in Figures 5a / 6a and 12a / 13a and a release position visible in Figures 5b / 6b and 12b / 13b.
    Guiding means are provided for moving the locking member between the locking position in which the upper edge (312) of the curved wall is in alignment with a portion of the lower edge of the endpiece. (231) of the transfer channel (Figures 7a / 8a / 9a) and the unlocking position in which the locking member (31) is spaced from the axis of symmetry (A) to leave free space to the plumb the tip (231) of the transfer channel so that this tip can be lowered to the valve stem to actuate (Figures 7b / 8b / 9b). These guide means consist on the one hand of a guide pin (33) fixed to the push button (20) and on the other hand of a guide slot (313) placed at the end of the push member. blocking opposite the fixing wall (32). When the push button is turned in one direction or the other, the guide pin (33) follows the same movement, driving with it the locking member (31).
    When the push button is in the locked position, the stop finger (25) bears against the locking stop (122), the locking member (31) is in the locked position, aligned with at least a portion of the lower edge of the tip (231) of the transfer conduit. If pressure is exerted on the push button in the direction of the valve, the lower edge of the nozzle (231) abuts against the upper edge (312) of the locking member: the tip can not reach the stem of the valve. This is the situation presented in Figures 7a, 8a and 9a. When the pushbutton is in the unlocked position, the stop finger (25) bears against the unlocking stop (123), the locking member (31) is in the unlocking position, away from the endpiece (231). so that there is no obstacle on the race of the latter towards the valve stem. If pressure is exerted on the push button in the direction of the valve, the nozzle encounters no obstacle and can slip on the rod to actuate the valve. In this case, the tip (231) passes in front of the notch (311) of the locking member. This is the situation presented in Figures 7b, 8b and 9b.
    Disengagement means are provided for removing the valve stem from the nozzle (231) of the transfer conduit when the push button is in the unlocked position. These uncoupling means are constituted by a ramp (124) placed between the locking abutment (122) and the unlocking stop (123). The further the boom moves away from the unlocking stop (123) to approach the lock stop (122), the further it deviates from the lower edge of the inner annular ring (12). The width of this ramp is chosen so that the stop finger (25) is at its vertical. In the locked position, the stop finger (25) bears against the locking stop (122) and its lower end (251) is in contact with the top of the ramp (124) while the end (231) of the transfer conduit is in abutment against the locking member (31). The push button is thus supported in three points: (i) at the level of the support rib (24) whose lower edge (241) bears against the upper edge of the inner ring (12), (ii) ) at the locking member (31) on which the lower edge of the end piece (231) and (iii) at the stop finger (25) whose lower end (251) is resting on the top of the ramp (124). These three points of support are marked in Figure 6a by the line (L). In the unlocked position, the stop finger (25) bears against the unlocking stop (123), its lower end (251) does not touch the ramp (124), or comes into contact with it, in its part lower (the closer to the lower edge of the inner ring), than when the push button is fully depressed with the valve in the open position. On the other hand, the support rib (24) is aligned with the bearing abutment (125) when there is one as in the first version. The alignment between (i) the bearing allowance (125), the axis of symmetry (A) and the bottom of the ramp is marked in Figure 6b by the line (L '). When the pushbutton in the unlocked position is depressed to actuate the valve, the lowest position that can take the push button, the nozzle (231) is plugged onto the stem of the valve. When the pressure exerted on the push button ceases, the valve closes and the rod resumes its closed upward position with the push button in an intermediate position, but without unmounting the tip of the rod. By turning the push button towards the locked position, the stop finger (25) comes into contact with the ramp (124) which it then follows, lifting the push button away from the valve. The tip (231) is then removed from the rod. In the locked position, the stop finger has raised the push button sufficiently for the locking member to fit between the nozzle (231) is the stem of the valve. The push button is in the highest position, the stop finger (25) bearing against the top of the ramp (124).
    It is possible to provide on the inner wall of the inner ring (12) of the hoop one or two extra thicknesses (126) and on the support wall (24) a vertical tongue (242) directed downwards. Figure 12a shows an extra thickness, Figure 5a two. The tongue (242) is placed on the support wall such that when the push button moves from the locked position to the unlocked position or vice versa, the tongue comes knocking the one or more thicknesses (126) by producing a click or two close clicks indicating that the push button is moving from one position to the other. It would be possible to place the overthickness so that clicks are heard only at the beginning and at the end of the rotation. It would also be possible to provide no extra thickness.
