    专利说明:

    The present invention relates to a fluid dispenser device.
    More particularly, the present invention relates to a fluid dispenser device of the single-dose or bidose type, adapted to respectively distribute a single dose of fluid in a single actuation or two doses of fluid in two successive actuations.
    To avoid accidental actuation of such a device, but also to generate an accumulation of energy in the user's hand to ensure full actuation, it is generally provided locking means in the rest position that the user must overcome when actuating. Typically, these locking means are formed between the body which supports the reservoir and the dispensing head with respect to which said body moves during actuation. The document EP0546607 describes such a device.
    This type of locking means has certain disadvantages. Thus, the reliability of the blocking is not always guaranteed, especially during transport or during a fall of the device. In addition, when the locking means comprise breakable bridges, this requires co-molding the body and the head, which can be complex and expensive. Bridges breaking between the body and the head also generate a significant radial size, which affects the compactness of the device. This implementation also prevents the provision of anti-tearing means, distinct from said breakable bridges between these two same parts, to protect the integrity of the reservoir and prevent access to the fluid contained therein.
    The present invention aims to provide a fluid dispensing device that does not reproduce the aforementioned drawbacks.
    More particularly, the present invention aims to provide a fluid dispenser device which ensures a reliable locking before actuation.
    The present invention also aims to provide such a device which combines locking means breakable bridges and separate anti-tearing means of said breakable bridges.
    The present invention also aims to provide such a device which is compact and compact, especially in the radial dimension.
    The present invention also aims to provide such a device that is simple and inexpensive to manufacture and assemble.
    The subject of the present invention is therefore a device for dispensing a fluid product, comprising a reservoir containing fluid, a dispensing head provided with a dispensing orifice, dispensing means for dispensing at least a portion of said fluid product through said dispensing orifice, and passage means for connecting said reservoir to said dispensing orifice during the actuation of said dispensing means, said passage means comprising a hollow needle penetrating into said reservoir during the actuation of said dispensing means, said needle being fixed in a needle holder itself fixed in said dispensing head, said needle support having locking means which, in the rest position, cooperate with said reservoir to prevent its axial displacement relative to said head.
    Advantageously, said locking means are deactivated when the user exerts an axial actuating force greater than a predetermined threshold between said reservoir and said dispensing head.
    Advantageously, said locking means comprise a locking element connected to said needle support by at least one breakable bridge.
    Advantageously, said locking element is a radial ring connected to said needle support by a plurality of breakable bridges.
    Advantageously, said dispensing means comprise a stopper-piston which in the rest position closes said reservoir in a sealed manner, and which during actuation is first pierced by said needle and then moved axially in said reservoir to expel the fluid to through said needle towards said dispensing orifice.
    Advantageously, said device comprises actuating means for actuating said dispensing means, said actuating means comprising a body fixedly receiving said reservoir, said body being able to slide axially with respect to said dispensing head.
    Advantageously, the device comprises anti-tearing means disposed between said body of said actuating means and said dispensing head.
    Advantageously, said anti-tearing means comprise an outward radial shoulder formed on said body and an inward radial shoulder formed on said dispensing head, the inner diameter of said radial inward shoulder being smaller than the outer diameter of said dispensing head. radial shoulder outward.
    These and other features and advantages of the present invention will appear more clearly in the following detailed description, with reference to the accompanying drawings, given as non-limiting examples, and in which:
    FIG. 1 is a diagrammatic cross-sectional side view of a fluid dispenser device according to an advantageous embodiment of the present invention, in the rest position before actuation,
    FIG. 2 is a view similar to FIG. 1, seen from behind,
    FIG. 3 is a view similar to FIG. 1, showing the device after actuation,
    FIG. 4 is a view similar to FIG. 2, showing the device after actuation,
    FIG. 5 is a cutaway perspective view of a fluid dispenser device according to an alternative embodiment of the present invention, in the rest position before actuation,
    FIG. 6 is a perspective view of the needle support of FIGS. 1 to 4, and
    Figure 7 is a bottom view of the needle holder.
    In the description, the terms "axial" and "radial" refer to the longitudinal axis A of the device shown in FIGS. 1 to 4. The terms "up" and "down" refer to the position of the device in the figures 1 to 4.
    With reference to the figures, the device comprises a reservoir 10 containing fluid to be dispensed, typically a liquid. This reservoir 10 is disposed inside a body forming a dispensing head 20. This dispensing head 20 has a dispensing orifice 21, which in the example of Figures 1 to 4, is oriented radially. This dispensing orifice 21 serves to dispense a dose of fluid product from said dispensing head 20. In a variant, this dispensing orifice could be oriented axially, in particular in a nasal dispensing head.
    The reservoir 10 is in this example formed by a hollow and blind body 11, having a single opening closed by a piston-cap 30. Other implementations are possible, for example an open tank on both sides, with a respective cap to close each opening. Documents W003041872 and FR2970955 describe tanks of this type.
    The dispensing head 20 comprises passage means 40 which, during actuation, connect the reservoir 10 to the dispensing orifice 21. These passage means 40 comprise a needle 41 adapted to pierce the piston stopper 30 at the time of actuation. of the actuation. This needle 41 is hollow, and can be formed in a conventional manner. This needle 41 is fixed relative to the dispensing head 20 and in particular with respect to the dispensing orifice 21. The needle 41 is fixed in a needle holder 60 which is itself fixed, in particular force-fitted, into the dispensing head 20. The needle support 60 advantageously comprises a hollow body 61 approximately cylindrical in which said needle 41 is fixed. Advantageously, internal axial ribs 63 are provided inside said hollow body 61 to center and fix said needle 41. External axial ribs 62 may also be provided on said hollow body 61, as can be seen in FIG. 6, whose function will be described below.
    Actuating means 50 are provided to enable actuation of the device. In this case, these actuating means 50 comprise a body 51 movable relative to the dispensing head 20, said body 51 cooperating with said reservoir 10 to move it relative to the dispensing head 20 and therefore with respect to the needle 41.
    Conventionally, in the device shown in Figures 1 to 4, the user places two fingers on the radial supports 22 formed on the dispensing head 20, and presses with the thumb on said actuating body 51. such an actuation, the reservoir 10 is thus urged axially upwards, so that the needle 41 will pierce the piston plug 30. The contents of the reservoir 10 is then connected to the dispensing orifice 21 and the support of the user on the actuating means 50 moves the piston plug 30 in the reservoir 10 to ensure the distribution of the fluid product. This plug-piston 30 then acts as a piston by pushing the fluid out of said reservoir 10, through the needle 41.
    In the case of a single-dose unit, all of the fluid product is dispensed in a single operation, whereas for a bidose, two successive operations are necessary.
    According to the invention, the needle support 60 comprises locking means 65,66 which in the rest position cooperate with the reservoir 10 to prevent its axial displacement relative to the head 20. When the user wishes to actuate the device, he must first overcome these blocking means.
    The locking means, more clearly visible in FIGS. 6 and 7, comprise a blocking element 66 connected to the hollow body 61 of the needle support 60 by at least one breakable bridge 65.
    In the example shown, the locking element is advantageously made in the form of a radial ring 66, and there are four breakable bridges 65. However, any number of breakable bridges can be envisaged.
    Alternatively, the locking element could be made differently. There could in particular be several separate locking elements 66, each connected to said hollow body by a respective breakable bridge 65.
    The locking means of the present invention are particularly advantageous in that they are simple and therefore inexpensive to manufacture, in particular to mold, and to assemble.
    When the user wishes to actuate the device, it exerts an axial force between the body 51 of the actuating means 50 and the radial supports 22 of the dispensing head 20. The body 51, and therefore the reservoir 10, can not move axially relative to the head 2 because of the locking means which cooperate with the top edge of the tank, as shown in Figures 1,2 and 5.
    When this axial force reaches a predetermined threshold, the breakable bridges 65 break, which allows axial sliding of said locking element 66 around the hollow body 61 of the needle support 60. Simultaneously, the body 51 and the tank 10 also move. axially with respect to the dispensing head 20, causing the piston plug 30 to be pierced by the needle 41 and then the piston plug 30 to be displaced in the reservoir to expel the fluid. Figures 3 and 4 show the device after actuation, with the locking member 66 at the top of said hollow body 61. The ribs 62 may serve to lock said locking member 66 after actuation, for example by clamping or snap.
    Said predetermined threshold of the axial actuating force at which the breakable bridges break ensures precompression in the hand of the user which ensures that the total actuating stroke will be performed when said breakable bridges break. This threshold can be chosen to ensure good anti-actuation safety during transport and storage, while allowing a not too difficult operation.
    The device advantageously comprises anti-tearing means 70 arranged between the body 51 of the actuating means 50 and the dispensing head 20, in order to prevent the user from having easy access to the fluid product contained in the reservoir 10.
    In the example shown, these anti-tearing means comprise an outward radial shoulder 71 formed on the body 51 and a radially inward shoulder 72 formed on the dispensing head, the inner diameter of said radial shoulder towards the inside 72 being less than the outer diameter of said radially outward shoulder 71. Thus, in the rest position, visible in FIGS. 1, 2 and 5, the radially inward shoulder 72 formed on the head 20 prevents removal. the body 51 and thus the reservoir 10 of the device.
    As shown in the figures, the fact of deporting the locking means at the level of the needle support 60 makes it possible to produce a device provided with both locking means, effective anti-tearing means and reduced radial dimensions. minimum.
    Of course, other embodiments are also conceivable, without departing from the scope of the present invention, as defined by the appended claims.
