In particular, the push button 2 comprises an internal well 7 for mounting on the feed tube 6 and a delivery path of the pressurized product from said well to a dispensing orifice 8. Furthermore, the push button 2 comprises an upper zone 9 allowing the user to exert a digital support on said push button in order to be able to move axially on its stroke of distribution to actuate the sampling device 1, the return of the push button 2 on its suction stroke being conventionally performed by an elastic return means.

In the embodiment shown, the push button 2 is equipped with a spray nozzle 10 which is arranged to form an aerosol with the product under pressure. The distribution path comprises a radial channel 11 which opens into the upper part of the well 7, said channel supplying a vortex chamber 12 provided between an anvil 13 of the push button 2 and the nozzle 10. However, the invention is not limited. to a particular mode of distribution of the product. In particular, especially for a nasal spraying nozzle, the push button 2 may allow axial distribution of the product.

In the lower part, the sleeve 5 has a housing 14 of association of the pump 1 which is mounted on the neck 3 of the bottle 4 to allow the supply of said pump packaged product in the tank. Moreover, in the upper part, the sleeve 5 has an internal chimney 15 in which is disposed the body of the pump 1. However, the invention is not limited to a particular mode of attachment of the pump 1 on the neck 3 In particular, the sleeve 5 can be integrated in the body of the pump 1, for example by forming a stent for said pump.

The pushbutton 2 has an inner skirt 16 which surrounds the well 7 forming an annular space in which the internal chimney 15 is arranged to guide the translation of the pushbutton 2 in the sleeve 5. More precisely, the well 7 has an extension 7a which is slidably mounted against the inner wall of the chimney 15 and the inner wall of the inner skirt 16 is slidably mounted against the outer wall of the chimney 15. Furthermore, a stop assembly 17 is formed between the inner skirt 16 and the chimney 15 to define the rest position of the push button 2 (figures).

The push button 2 also comprises an outer skirt 18 which is slidably mounted in an outer chimney 19 of the sleeve 5 between a high position (FIGS) and a low position delimiting the dispensing / suction stroke of the product. The outer skirt 18 comprises a lower edge 18a provided with a notch 20 which has an upper edge 20a disposed above the outer chimney 19 when the skirt 18 is in the upper position.

The indentation 20 is equipped with a first-use indicator 21 comprising, on either side of the upper edge 20a, an inner part 21a which is held on the inner face of the skirt 18 and an outer part 21b which is connected to said inner portion via a frangible zone 21c. In particular, the first use indicator 21 is a separate part of the pushbutton 2, said part being attached to the notch 20.

To do this, the embodiment shown provides that the inner 21a and outer 21b parts form between them a housing in which the upper edge 20a of the notch 20 is inserted to hold the control 21 on the skirt 18 of the push button 2. In this embodiment, the inner portion 21a may be fixed on the inner face of the skirt 18, for example by gluing or by clipping, so as to remain attached to the skirt 18 after rupture of the frangible zone 21c. Alternatively, the housing may be arranged to clamp the witness 21 on the skirt 18, said clamping being sufficient to hold said witness on said skirt, the inner portion 21a then being detached from said skirt after rupture of the frangible zone 21c .

The provision of the control 21 in the notch 20 allows a good visualization of the first use. In particular, the outer portion 21b may be disposed facing the outer face of the skirt 18 to be clearly visible. Furthermore, the inner portion 21a shown comprises a lower bead 21d whose axial dimension is at least equal to the axial dimension of the notch 20, said bead then being disposed under the outer portion 21b to be visible to the user in said notch.

In addition, the indicator 21 being reported, it can be made in a material different from that of the push button 2 and / or have a different color, including a bright color such as red. Moreover, the rupture of the frangible zone 21c is irreversible so as to make reliable the identification of the first use.

In the embodiment shown, the upper edge 20a of the notch 20 is surrounded by two lateral edges 20b, 20c to have a substantially rectangular geometry. In particular, the side edges 20b, 20c may be spaced at least 10 ° on the periphery of the lower edge 18a of the skirt 18. Thus, by providing that the outer portion 21b extends longitudinally between the side edges 20b, 20c said outer portion may be of sufficient size to properly display the first use.

Furthermore, the outer portion 21b is protruding radially from the chimney 19 so as to require the removal of said outer portion to release the sliding of the skirt 18 to its lower position. In particular, the outer portion 21b has a substantially radial lower edge 21e from which the frangible zone 21c extends internally, said edge being disposed above the upper edge 19a of the chimney 19, with a small axial clearance so as to prevent the sliding of the skirt 18 in the chimney 19. And, after removal of the outer portion 21b by rupture of the frangible zone 21c, the distribution of the packaged product is allowed by actuation of the push button 2 on its dispensing / suction stroke of said product .

In the embodiment shown, the outer portion 21b is movable manually relative to the skirt 18. To do this, the outer portion 21b is not fixed on the outer face of the skirt 18 and may have a shape and a shape. size adapted to facilitate manual gripping.

Furthermore, the frangible zone 21c is arranged to be broken by the displacement of the outer portion 21b with respect to the skirt 18 and thus with respect to the inner portion 21a. In particular, the frangible zone 21c has a reduced thickness to be broken and the control 21 can be made of brittle plastic, for example plastic of the styrenic family.

In the embodiment shown, the outer portion 21b is movable between a position against the outer face of the skirt 18 (FIGS) and a position remote from said outer face, the passage between these positions being made by rotation at the level of the zone. frangible 21c so as to break said frangible zone.

Moreover, the frangible zone 21c may be disposed in the axial extension of the upper edge 19a of the chimney 19 so, by actuation of the push button 2, to induce the breaking of said frangible zone by pressing on said upper edge. Thus, during the first use, even if the user fails to manually break the frangible zone 21c by displacement of the outer portion 21b, the dispensing / suction stroke can be released by breaking the first-use indicator 21.

In the embodiment shown, the lower edge 21e of the outer portion 21b is disposed above the upper edge 19a of the chimney 19, the frangible zone 21c being disposed axially facing an inner zone of said chimney. More specifically, the upper edge 19a of the chimney 19 8 has a chamfer 22 against which the frangible zone 21c is broken, said chamfer comprising an inclined face 22a provided with an internal sharp edge 22b axially opposite which the frangible zone 21c is disposed, said edge being arranged to promote the breaking of said frangible zone against it.

Furthermore, again to facilitate breaking the frangible zone 21c by pressing the push button 2, the embodiment shown provides that the upper edge 20a of the notch 20 has a lower projection 20d against which the frangible zone 21c is disposed. so as to confer a guillotine effect promoting the rupture of said zone.
