The present invention relates to the field of packaging containers or dispensers of cosmetic products, and more particularly dispensers of makeup products based on powder, typically free-running powder.
THE PRIOR ARTCases forming powder dispensers, typically of compacted powder, are already known.
Generally speaking, these cases typically include:
a concave lid generally fitted with an inner mirror,
a concave bottom, typically fitted with a grid or intermediate support for at least one pot intended to receive said cosmetic product,
a hinge, constituting the connection component between said lid and said bottom, allowing said lid to articulate and said case to open,
a clasp or any means of locking and unlocking said lid relative to said bottom,
a means of applying said powder, typically a powder puff, typically inserted between said bottom and said mirror.
A very large number of case embodiments are known, embodiments which can relate to one or more of the constituent parts of the case, particularly to the clasp or to the opening of the case.
Thus, as far as patents in the name of the applicant are concerned, we may mention:
patent FR 2 661 080 which describes a makeup case with a compact clasp,
patent FR 2 725 958 which relates to a case with combined assisted opening and closure,
patent FR 2 737 192 which describes a case with a pivoting lid provided with an articulation with flexible lugs,
patent FR 2 755 352 which describes a case with assisted opening,
patent FR 2 755 353 which describes a case with an unlocking and pre-opening push button,
patent FR 2 794 723 which describes a case with improved pre-opening.
Dispensers of “free-running” powder, as opposed to said compacted powder, are also known, which include a brush used to apply said powder, as described in French applications nos. 9915615 and no. 0104572.
Problems Posed
Free-running powder dispensers of the prior art have a number of different drawbacks:
on the one hand, they are dispensers which generally include a brush integral with a powder holder, and which are therefore relatively complex.
on the other hand, these dispensers, largely on account of their complexity, do not lend themselves very easily to miniaturisation,
finally, largely on account of the large number of parts required in their manufacture, they are difficult to make leakproof, even though powders increasingly include volatile constituents that require leakproof dispensers.
DESCRIPTION OF THE INVENTIONAccording to the invention, the dispenser for a product in powder form, typically a cosmetic product, includes a body forming a cavity intended to contain said product in powder form and fitted with an upper aperture, a means of applying said powder, and a cap intended to seal said upper aperture via an engagement means, and is characterised in that:
a) said engagement means is selected in such a way that an axial and/or radial compression is exerted between said body and said cap, and that said cavity is thus typically leakproof when said dispenser is closed,
b) said cavity includes a lower part and an upper part separated by a plate integral with said body and fitted with orifices, said lower part containing said product in powder form, said plate allowing said product to move, via said orifices, towards said application means,
c) said application means is a removable application means.
The combination of means according to the invention allows the problems posed to be resolved. Indeed, on the one hand, the dispenser according to the invention therefore typically includes three parts: a body containing said powder, a cap and a means of applying said powder, resulting in fact in a dispenser of great simplicity. On the other hand, this dispenser, largely on account of this simplicity, may be made in different sizes, and particularly in sizes that are sufficiently small for said dispenser to become a so-called travel or handbag item.
Finally, the engagement between said cap and said body renders the container leakproof, insofar as the dispenser according to the invention allows an engagement of said body and cap with particularly an axial and/or radial compression between the skirts of said body and cap which can be adjusted so as to obtain the required degree of leakproofing, typically a high degree of leakproofing.
DESCRIPTION OF THE FIGURES

It should be noted that in
According to one embodiment of the dispenser of the invention, said plate (5, 24) may form a distinct plate (5) that can be fixed to said body (2), typically by being snapped on or fitted axially, said plate (5) being fixed to said body (2), typically after said lower part (22) has been loaded with said powder.
This embodiment has been shown in
In this embodiment, said plate (5) is inserted through the upper aperture (21) of the body (2) and is pushed until the plate (5) comes to a stop against an obstacle.
To this end, said body (2) may include an inner shoulder (25) forming a stop for said snapping-on or said axial fitting, as shown in
Said plate (5) may include an outer rim (51) engaging with said inner shoulder (25). See for example
According to another embodiment of the invention, and as shown in
Typically, said cap (3) may include a mirror (6) fixed to its inner surface. See for example
According to the invention, said body (2) may include a lateral skirt or wall (26) fitted, in its upper part, with an outer channel (260), and wherein said cap (3) includes a lateral skirt or wall (30) engaging with said outer channel (260) , in such a way that there is typically a surface continuity and a linear extension between said body (2) and said cap (3) when said dispenser (1) is closed. See for example
But, as shown for example in
As shown in
It might also engage by axial compression with a cap (3) exerting said axial compression when typically it is screwed onto said body (2). This variant has not been shown in a figure.
As shown in the figures, said cap (3) may include a typically plane dome (31). But the invention is not restricted to one particular type of dome; indeed, said dome could be rounded, knowing that the mirror (6) may be fixed to or snapped into any type of dome.
According to the invention, the combination of essential means of the dispenser does not impose on said dispenser (1) any given outer shape.
Thus, by way of example, and as shown in
As shown in the figures, said body (2) may include a typically plane bottom (27). However, since the dispensers (1) may be so-called nomad dispensers (1) from their capacity for being carried in a handbag, and since they do not therefore have to be placed in a vertical position on a support, the bottom (27), whether it is formed by said body (2) itself, as shown in
According to the invention, said application means (4) may include an application material (41) of elasticity and thickness selected in such a way that, when said dispenser (1) is closed, said application material (41) is set against said plate (5, 24), and that it typically seals said orifices (50, 240).
Said removable application means may be a powder puff, as shown in
As shown in
As shown in
As already mentioned, said dispenser may take any shape.
Typically, and as shown in the figures, said body (2) and said cap (3) may be cylindrical in shape, and wherein said dispenser (1) is of axial symmetry and has, when closed, the ratio of H to D of between 0.85 and 1.25, H and D denoting the height and the diameter respectively of said closed dispenser, with H being between 15 mm and 150 mm, and typically between 30 mm and 60 mm in the case of so-called nomad dispensers.
As can be seen in
According to the invention, said body (2) and said cap (3) may be formed of parts moulded in a plastic material that, particularly by their nature and thickness, provide leakproof packaging for said product.

As shown in
All the figures constitute examples of embodiments of dispensers (1) according to the invention.
Dispensers have been made that are truncated cone shaped as in
Dispensers have been made that are cylindrical as in
These dispensers were made by moulding thermoplastic material.
ADVANTAGES OF THE INVENTION The invention on the one hand allows cost-effective and leakproof packaging for any type of powder, and on the other hand makes it possible to offer a good alternative to conventional cases for packaging powder in the form of a compacted block.
