DETAILED DESCRIPTION OF THE INVENTION

According to one embodiment of the invention, said connecting means (4) can be chosen to allow the manual separation of at least one of the containers Ri. Said connecting means (4) may comprise at least two connection points (40) between said container Ri and said corresponding Si support portion (20), connection points (40) typically symmetrical with respect to said axial direction Ai.
As can be seen in FIGS. 1a or 2a, the Si support portions (20) are separated from each other by mid-lines (201) between the containers, or by hinge or line-of-rupture lines (202).
Preferably, and illustrated in the figures, said connecting means (4) may comprise four connection points (40), two being located at said neck (31), the two others being located at said bottom (34).
Typically, said connecting means (4) may be formed by a material bridge or material thinning, made of a same plastic material or forming the junction of two different plastic materials, capable of being broken manually, connecting said container Ri to said portion If, by snapping or clipping elements of the container Ri cooperating with elements of said support portion Si, or by these two means simultaneously.
It is simply important that the containers R (3) remain integral with their support S (2) as long as the end user does not wish to consume the contents of a container R.

According to one embodiment of the invention, which said support S (2) can form a perforated plate (5) of thickness chosen to form a rigid or semi-rigid support S. Such a plate is therefore distinguished from all materials in flexible films.
Such a perforated plate (5) appears in FIGS. 1a, 1c, 2b, 2c, 3 and 4, etc.
According to another embodiment of the invention, said support S (2) may form a trellis or chain (6), comprising connecting lugs (60) intended to form all or part of said connecting means (4), as illustrated in Figures 6 to 6b. Thus, one can include in the rings of a chain or in frames, interconnected by rings or a hinge, rings or frames forming said support portions (20) for said containers R.
This modality, like the previous one, opens many practical possibilities of realization.

According to the invention, said support (2) can be made of plastic, typically polyolefin. It can also be metallic, typically aluminum or steel stainless steel, or in the form of a band or wire having sufficient rigidity for said assembly to maintain said containers in a predetermined position.

According to a variant of the invention, said portions of Si supports (20) are typically all identical, so as to offer different product doses or replacement doses of the same product.
This is one of the possibilities of using the distributor assembly (1) of the invention.
But, according to another variant, said containers Ri (3) and said portions of supports Si (20) may not be identical, so as to offer a combination of typically complementary products, or different capacities of the same product.
Thus, the different containers Ri (3) may be different or different and contain different products, typically care products, makeup or beauty, the type of creams, nail polish, lotions, or any other fluid used for them. body care.
The different containers Ri can thus be used to produce mixtures or compositions during their use, for example, a container Ri can contain a powder, to be mixed with a liquid contained in a neighboring container Ri; or again, a container Ri may contain a first active ingredient, and the container Rj a second active ingredient, to be mixed with the first in use.
It can also be envisaged that the different contents of the containers Ri form a range or a palette of colors.

According to the invention, at least one of said containers Ri (3) can be a container obtained by injection-blow molding of a plastic material, for example a polyolefin (PE, PP). But, preferably, all the containers Ri (3) are obtained by injection-blowing.
On a practical level, it is advantageous for said support S (2) and all the receptacles Ri (3) to form a one-piece piece of plastic material, the receptacles Ri being connected to the support portions Si by plastic bridges ( 41).
Figures 1 to 5 in particular correspond to this modality.
However, even in this case, the material constituting said support S (2) may or may not differ from that constituting said containers Ri (3), typically by nature or color. The supports and / or containers may be translucent.
In addition, said support S (2) can be surface treated and typically carry information or a decoration, obtained in particular by printing or labeling.
The possibilities of the present invention are readily conceivable to form a wide variety of objects that are both aesthetic, novel, functional and economical to manufacture.

According to the invention, the number of portions of supports Si (20) or that of containers Ri (3) can be typically between 2 and 20, and typically from 4 to 8, said support portions Si which can be articulated or not between they, or comprise hinge elements (201), and optionally a spacer panel (24), so as to fold, or wind on itself said assembly (1).
Typically, said neck (31) may be closed by a cap (7), screwed or snapped to said neck, said cap (7) optionally carrying an application means, typically a brush (70), as shown in Figure 2d.
Generally, said container Ri is centered with respect to said recess Ei, so as to form, except at the location of said connection points, a space or gap (25) between said contour Ci and said container Ri of a thickness that is typically constant and understood between 0.5 and 5 mm. From an aesthetic point of view, it may be preferable for the contour Ci and the profile of the container Ri to be homothetic, with a spacing (25) that is substantially constant, so as to make better use of the container Ri, as illustrated for example in FIG. .

According to a variant of the invention, said support portions Si (20) forming said S support can form manually separable elements, typically through a weakening line or means (202) separating the support portion Si and the next support portion Sj, and wherein each container Ri remains attached to said corresponding Si support portion. Since, according to this variant, the portions of If (20) are separable from each other, it is no longer necessary for the Ri containers are dissociable from the corresponding support portions Si. So, when blowing the container, it is not necessary to keep a gap (25), the contour C of the support portion Si which can eventually melt into the wall of the container body Ri.

As illustrated by way of example in FIGS. 2c, 6a and 6b, said support S or support portions Si can / can form or understand station means predetermined, typically vertical station, so that said containers stay straight.
