The system also comprises an outer wrap 8 inside which the bottle 1 is intended to be housed, especially for aesthetic purposes masking said bottle. To do this, the outer envelope 8 may be formed from a material more expensive than that of the bottle 1, for example a plastic or glass material, and may eventually be provided with decorations.

In relation to the figures, the envelope 8 has a substantially cylindrical outer geometry. In a variant, the envelope 8 can have external geometries of varied sections, for example rectangular, elliptical or polygonal, according to the desired aesthetic effect.

The wrapper 8 comprises an inner housing 9 for the reception of the bottle 1, said housing especially presenting a complementary geometry of the outer geometry of the said bottle. In relation to the figures, the outer envelope 8 comprises a lower portion 8a that delimits a lower housing 9a for the reception of the lower portion 2a of the body 2. In addition, the lower portion 8a comprises a bottom 10 having a lower opening arranged for allow the arrangement of the bottle 1 inside the wrapper 8.

The envelope 8 further comprises an upper portion 8b delimiting an upper housing 9b for receiving the neck 5 and the upper portion 2b of the body 2. In particular, the upper portion 8b extends axially from the lower portion 8a forming a shoulder radial 11 thereof under which the lower shoulder 4 of the bottle 1 abuts during the arrangement of said bottle inside said envelope 8. In addition, the upper portion 8b has an upper opening 12 arranged to allow access to the neck 5 when the bottle 1 is housed inside the wrapper 8, especially in order to fill said bottle.

In particular, the axial maintenance device is provided at the interface between the lower part 5a of the neck 5 and the upper opening 12 of the envelope 8, in which said lower part is arranged when the bottle 1 is housed inside The aforementioned wrap. To do this, the throat 13 is formed in one between an annular support surface 28 extending in the lower part 5a of the neck 5 and a support surface 29 extending in the upper opening 12 of the envelope 8, being formed ramp 16 on the other of said support surfaces.

In the embodiment shown, the throat 13 is formed on an annular support surface 28 that extends in a lower part 5a of the neck 5. More precisely, the bottle 1 comprises an upper radial wall 14 that extends around the neck 5, especially from an upper portion of its lower part 5a, and having at least one annular recess 15, the throat 13 being formed on an annular support surface 28 extending between the upper wall 14 and the upper shoulder 7 of the cited jar.

In addition, the ramp 16 is formed on an annular support surface 29 extending in the upper opening 12 of the envelope 8, especially in the vicinity of the upper extremity of the upper portion 8b of the envelope 8.

Thus, the annular support surfaces 28, 29 are arranged so that the neck 5 of the bottle 1 disposed inside the envelope 8, especially its upper part 5b on which a product distribution device 6 is intended to be mounted , protrudes from the upper opening 12 of said envelope.

In relation to the figures, the upper radial wall 14 has legs 17 that delimit between sf emptyings 15, the maintenance device comprising radial ramps 16 that are angularly spaced being arranged to be able to be introduced axially into the throat 13 through respectively a recess fifteen.

In particular, the legs 17 are distributed symmetrically with respect to a longitudinal plane, in order to axially balance the maintenance of the bottle 1 inside the wrapper 8. On the other hand, as it is especially represented in Figure 1c, each leg 17 extends angularly between a radial bottom 17a and an edge 17b tangential to the annular support surface 28 of the lower part 5a of the neck 5.

To assemble the packaging system, the bottle 1 is introduced into the wrapper 8 through the bottom opening of its bottom 10, especially so that each emptying 15 is arranged axially opposite a ramp 16 respectively, then displaced on an axial stroke to remain arranged inside the said wrapper, in order to introduce each ramp 16 into the throat 13 through said emptying facing each other.

In relation to Fig. 3b, at the end of the axial stroke, each ramp 16 is arranged in a recess 15 so that its proximal edge 16a is angularly arranged in front of a radial edge 17a of respectively a leg 17. Next, by rotation relative of the bottle 1 inside the envelope 8, the ramp 16 is introduced by its proximal edge 16a in the throat portion 13 formed between the leg 17 and the upper shoulder 7, and this until it is immobilized axially in said portion of throat, with its axial edge 16b arranged in front of the radial edge 17a of said leg, as shown in Figure 3d.

The maintenance device also has means which form the end stop of the ramps 16 in the throat 13 during the relative rotation of the bottle 1 with respect to the wrapper 8.

To do this, in relation to the figures, each ramp 16 has a flange 18 extending axially from its distal edge 16b, said flange being arranged to abut the upper radial wall 14, especially on a radial edge 17a respectively a leg 17 (see figure 3d), at the end of the angular stroke of said ramp in the throat 13.

In order to angularly immobilize the ramps 16 in the throat 13, and thus block the axial maintenance device, said ramps and the upper radial wall 14 have redprocoal angular end-of-stroke interlocking means of said ramps in said throat 13.

To do this, in relation to FIGS. 2, each ramp 16 comprises a groove 19 formed in the vicinity of its distal edge 16b, and in which it is intended to engage a reed 20 of the upper wall 14. Also, as shown in FIG. 1d, the reed 20 is formed on a free edge that delimits a recess 15 of the wall 14, especially on the radial edge 17a of each leg 17, said edge being equipped with a stiffening reinforcement 21.

On the other hand, in order to reinforce the angular immobilization of the ramps 16 in the throat 13, said throat and / or said ramps can have an axial dimension that is variable so that said ramps remain in axial interference in said throat at the end of the angular stroke.

To do this, in relation to Figures 2a and 2c, each ramp 16 has an axial thickness that increases continuously from its proximal edge 16a towards its distal edge 16b. Thus, the axial thickness of the ramp 16 is maximum at the level of the distal edge 16b, especially being substantially equal to the axial dimension of the throat portion 13 in which said ramp is introduced by axial rotation.

In order to rotate the bottle 1 in rotation when it is housed inside the envelope 8, the bottom of the bottle comprises a footprint 22 which is arranged to allow the said bottle to rotate inside the envelope 8, by example by introducing a tool in the mentioned footprint.

In relation to Figure 4a, the packaging system further comprises a cap 23 intended to be associated with the bottom 10 of the wrapper 8 to hide the lower opening, especially after the arrangement of the bottle 1 inside the wrapper 8. In particular, the cap 23 comprises a teat 24 intended to be introduced in the footprint 22 of the bottle 1 during the association of said stopper in the bottom 10.

Once the packaging system and the packaged product are assembled in this way, a distribution device 6 can be mounted on the upper part 5b of the neck 5, especially by axial deformation, in order to form a set of 10 distribution of the packaged product in the aforementioned system, the axial maintenance device being sufficiently resistant, especially due to its structure and its arrangement, to avoid the deolidarization of the bottle 1 and of the envelope 8 during said axial deformation.

In the embodiment shown, the distribution device 6 is a pump operated by a push button 25 equipped with a distribution hole 26. In particular, the pump 6 comprises a peripheral bottom skirt 15 that surrounds the upper portion 8b of the envelope 8 during the assembly of said pump, especially abutting the radial shoulder 11 of said envelope, in order to mask the said upper portion and improve the aesthetics of the distribution assembly.

On the other hand, the distribution assembly comprises a cap 30 intended to be reversibly arranged around the push button 25 between two uses, especially being inserted in contact 20 adjusted on the peripheral lower skirt 27.
