DETAILED EXPLANATION OF IMPLEMENTATION METHODS

[0015] There Fig. 1 shows an assembly 100 according to the invention. This assembly 100 comprises a bottle 102, an aesthetic collar 104 and a dispensing mechanism 106 which here takes the form of a manual pump activated by a user's hand and which plunges into a reservoir (120, Fig. 3 ).

[0016] In the following description, terms relating to a position are taken with reference to an assembly 100 in its normal operating position, that is, as it is represented on the Fig. 1 . In the following description, and by convention, Z is called the vertical direction oriented positively upwards.

[0017] There Fig. 2 shows assembly 100, in which the aesthetic fret 104 has been raised and the Figs. 3 à 5 show cross-sections of assembly 100.

[0018] Assembly 100 includes a distribution unit which includes the reservoir 120 and the distribution mechanism 106 attached to the reservoir 120.

[0019] The bottle 102 comprises a hollow body 112 and a neck 114 which is integral with the hollow body 112 and at the top thereof. The neck 114 defines an access opening 110 into the hollow body 112 through which passes the dispensing mechanism 106, which is connected to the reservoir 120 housed within the hollow body 112. The reservoir 120 can contain any type of fluid product, such as a cream, and the dispensing mechanism 106 is designed to draw the fluid product from the reservoir 120 and discharge it from the reservoir 120 to the outside through a hole 122 provided for this purpose in the dispensing mechanism 106. The means of the dispensing mechanism 106 that transport the fluid from the reservoir 120 to the hole 122 are not described further, as they are not directly within the scope of the invention and can take various forms known to those skilled in the art.In the description, orifice 110 and the various windows described above and below are coaxial with the vertical Z direction.

[0020] The aesthetic fret 104 has a first plate 104a which extends horizontally and is crossed by a first window 104b through which passes the distribution mechanism 106.

[0021] The aesthetic fret 104 also includes a first outer skirt 104c extending downwards from the outer periphery of the first plate 104a, i.e. the outer edge of the first plate 104a.

[0022] The aesthetic fret 104 is positioned on the neck 114.

[0023] The assembly 100 also includes a hanging system 108 which is integral with the aesthetic collar 104 and ensures its attachment to the neck 114 of the bottle 102 and which, in the assembled position, is housed inside the aesthetic collar 104 and outside the dispensing mechanism 106. Here, the hanging system 108 consists of a molded plastic part, but it can be made of any material having the appropriate physical properties, in particular, it can be made by 3D printing.

[0024] The hanging system 108 includes a second platform 108a which extends horizontally and is crossed by a second window 108b through which passes the distribution mechanism 106.

[0025] The hanging system 108 also includes an inner skirt 108d which is integral with the second tray 108a, and which extends downwards from the inner periphery of the second tray 108a, i.e. from the edge of the second window 108b, thus delimiting from the second window 108b, a well in which the distribution mechanism 106 is housed.

[0026] The attachment system 108 also includes a second outer skirt 108e attached to the second plate 108a and extending downwards from the outer periphery of the second plate 108a, i.e., the outer edge of the second plate 108a. The second outer skirt 108e is applied against the inner face of the first outer skirt 104c. In the assembled position, the attachment system 108 is housed inside the aesthetic fret 104 and overlaps the neck 114 such that the second plate 108a is located between the neck 114 and the first plate 104a of the aesthetic fret 104, and such that the inner skirt 108d is between the neck 114 and the distribution mechanism 106, and the second outer skirt 108e is between the neck 114 and the first outer skirt 104c.

[0027] The aesthetic flange 104 is attached to the hanging system 108 by any suitable fastening means. In one particular embodiment, the attachment is achieved by a tight fit between the first outer skirt 104c and the second outer skirt 108e. In another particular embodiment, the attachment is achieved by bonding. In yet another particular embodiment, the attachment is achieved by a tight fit between the first outer skirt 104c and the second outer skirt 108e and by bonding.

[0028] To hold the reservoir 120 when it is placed in the bottle 102, the assembly 100 has retaining lugs 126 which are integral with the inner skirt 108d and which extend generally perpendicularly to the vertical direction Z and inwards, that is to say opposite the neck 114 and therefore in the direction of the reservoir 120.

[0029] The distribution assembly has at least one groove 150 which extends around the perimeter of said distribution assembly and which is open outwards, i.e. towards the bottle 102. In the assembled position, each retaining lug 126 fits into a groove 150 so as to lock the reservoir 120 relative to the bottle 102. The retaining lugs 126 therefore exert no radial force on the reservoir 120 or on the distribution assembly but only a locking force which prevents the movement of the reservoir 120 parallel to the vertical direction Z, unless a tensile force is exerted on the reservoir 120 which exceeds the locking force and causes the retaining lugs 126 to retract to allow the reservoir 120 to pass, for example for its filling or replacement.

[0030] Each retaining lug 126 thus rests downwards against a lower edge of the groove 150 and upwards against an upper edge of the groove 150.

[0031] With such an arrangement, implementation is easy.

[0032] According to a particular embodiment, each groove is made around the perimeter of the 120 tank.

[0033] In the embodiment of the invention presented to Figs. 2 à 5 , the distribution mechanism 106 includes a cap 106a, which is fixed onto a neck 120a of the reservoir 120 here by screwing.

[0034] The reservoir 120 and the cap 106a are arranged so as to present between them a vertical gap J, that is to say parallel to the vertical direction Z and each groove 150 is thus defined between the reservoir 120 and the cap 106a and it is delimited at the level of the gap J, at the top by the cap 106a and at the bottom by the reservoir 120. Each retaining lug 126 thus comes to rest downwards against the reservoir 120 and upwards against the cap 106a.

[0035] The clearance J is determined here between the lower part of the cap 106a and a shoulder of the reservoir 120, where the shoulder forms a narrowing to join the neck 120a.

[0036] In the embodiment of the invention presented here, the cap 106a comprises an inner cap 106b and an outer cap 106c fixed onto the inner cap 106b, here by snap-fitting.

[0037] The inner cap 106b has a thread to attach to a thread of the neck 120a of the tank 120.

[0038] The distribution mechanism 106 also includes a push button 106d in which the hole 122 is made. The push button 106d is mounted inside the cap 106a and a user presses the push button 106d to operate the distribution mechanism 106.

[0039] The inner cap 106b has lugs 107a which are best seen on the Fig. 6 The lugs 107a extend outwards and downwards from a skirt of the inner plug 106b, and the outer plug 106c has, for each lug 107a, a counter-lug 107b that extends inwards and upwards from a skirt of the outer plug 106c. Thus, when the outer plug 106c is threaded onto the inner plug 106b, the counter-lugs 107a are pushed in beyond the lugs 107a, and each lug 107a and its associated counter-lug 107b then come vertically opposite each other to prevent the outer plug 106c from being pulled upwards.

[0040] In the embodiment of the invention presented here, it is the stopper 106a which passes through the first window 104b, the second window 108b and the inner skirt 108d, and more particularly here the outer stopper 106c.

[0041] In the embodiment of the invention presented here, the fastening system 108 is housed outside the plug 106a and more particularly here outside the outer plug 106c.

[0042] In the assembled position, the inner skirt 108d is between the collar 114 and the plug 106a (here the outer plug 106c).

[0043] In the plane of the opening 110, which is perpendicular to the vertical direction Z, the outer perimeter of the neck 114 takes the form of a rectangle with rounded corners, and more specifically, a square with rounded corners. Similarly, the aesthetic fret 104 also takes the form of a rectangle when viewed from the vertical direction Z. The rectangular shape of the outer perimeter of the neck 114 and the rectangular shape of the aesthetic fret 104 limit the risk of the aesthetic fret 104 rotating around the vertical direction Z.

[0044] At each corner and along the height of the collar 114, said collar 114 is divided into a lower part 114a and an upper part 114b. The lower part 114a extends upwards from the hollow body 112 and the upper part 114b extends upwards from the lower part 114a.

[0045] At each corner, the lower portion 114a has an inward recess 116, meaning that the upper portion 114b overhangs the recess 116, thus defining a shoulder beneath the upper portion 114b. The recess 116 is present here only at the corners, which reduces the thickness of the neck 114 between two corners. The angular extent around the vertical direction Z of the recess 116 is, for example, 20° on either side of the corner.

[0046] In the assembled position, the aesthetic fret 104 is positioned on the neck 114 and the first outer skirt 104c descends to the hollow body 112.

[0047] The 108 attachment system also includes 108c attachment lugs (here four in number) attached to the second platform 108a and more particularly here to the second outer skirt 108e.

[0048] Each hooking lug 108c is arranged so that in the assembled position, it is positioned under one of the shoulders of the neck 114, i.e. in one of the recesses 116, to ensure the attachment of the hooking system 108 to the neck 114. Each hooking lug 108c is oriented perpendicular to the vertical direction Z and inwards.

[0049] The distribution assembly 106, here the outer plug 106c, has a groove 109 that forms a peripheral external relief around the outer plug 106c and rests against the first plate 104a, and whose diameter relative to the vertical direction Z is greater than the diameter of the first window 104b. Such a groove 109 prevents the distribution assembly from sinking relative to the first plate 104a, particularly when the bottom of the reservoir 120 does not touch the bottom of the hollow body 112. A contrario, when the tank 120 and the hollow body 112 are dimensioned so that the bottom of the tank 120 touches the bottom of the hollow body 112 when it is in position, then the groove 109 is not required.

[0050] The position of each retaining lug 126 is such that when the distribution assembly rests on the first plate 104a via the groove 109, each retaining lug 126 is in contact with the lower edge of the associated groove 150, here the shoulder of the reservoir 120, which results in the appearance of a support force which presses the distribution assembly downwards and thus holds the reservoir 120.
