Description

Housing for at least partially receiving a cosmetic applicator

technical field

The invention relates to a housing for at least partially receiving a cosmetic applicator, comprising a holder for holding the applicator in the housing, and a housing sleeve at least partially delimited for Receiving space for the applicator.

Background technique

Housings of the type described at the beginning of the description are known. The problem that arises with the known housings, especially when they are used for highly viscous cosmetic products, is that the lack of fluidity of the cosmetic product does not follow the force of gravity, so that the working area of the applicator cannot be properly loaded even when tilted or rotated . Consequently, it often happens that the case and the applicator have to be thrown away, although there is still cosmetic product in the case.

US-A-5 951 186 discloses a housing with a retainer which is axially displaceable relative to the housing. US-A-5 002 415 discloses a housing containing an applicator and having a bellows arrangement. A threaded retainer is known from DE 197 44 181 A1.

Contents of the invention

The object of the present invention is to further develop the housing of the type described at the beginning of the description in such a way that a better outflow can be achieved even for relatively high-viscosity cosmetic products.

According to the present invention, the above objects are achieved by providing a housing for at least partially receiving a cosmetic applicator, said housing comprising a holding area for holding the applicator in the housing and housing sleeve wherein the housing sleeve at least partially delimits a receiving space for the applicator; it is characterized in that: the relative position of the holding area relative to the housing sleeve can be adjusted in a pivotal manner; and A deformable connection is provided between the holding region and the housing sleeve.

In this respect the invention is based on the discovery that by means of the relative position of the holder with respect to the housing sleeve, the relative position of the working area of the applicator will also change with respect to the housing sleeve so that what actually occurs Yes: The working area of the applicator moves towards the cosmetic product which has a high viscosity and therefore cannot flow under certain conditions, or is able to move into the product to remove the cosmetic product so that the outflow is overall increased.

According to a particularly concisely preferred embodiment, a deformable connection is provided between the holder and the housing sleeve. In such a case, the deformation of the connecting means involves an adjustment of the relative position of the holder with respect to the housing sleeve, ultimately resulting in a relative movement of the working area of the applicator in relation to the cosmetic product. In this way, makeup residues can be easily removed.

Preferably, the connecting device has a bellows section. This structure also relates to a housing construction according to the invention which has particularly simple properties.

The bellows part in the housing may have one, two or more inwardly projecting parts and/or one, two or more outwardly protruding parts, wherein the determination of this aspect depends on the one hand Depending on the given geometry, on the other hand depends on the desired appearance of the shell.

The cross-section of the connecting means may be an angular or arc-shaped contour. Decisions in this regard are specifically considered in design considerations.

Said connecting means according to the invention preferably comprise an elastomeric material. The material is not only applied to structures with bellows sections. Rather, according to the invention, a specialized elastomer may be the reason for the adjustable relative position of the retainer with respect to the housing sleeve.

A further preferred embodiment of the invention provides a cover device for at least partially covering said connection device. Such a cover arrangement is provided in particular for two reasons. On the one hand, it is used to trap the connection device if it is not desired to be seen for aesthetic reasons. On the other hand, the cover device can also convey information about the color of the cosmetic product, for example by means of colouring.

The housing can theoretically be of any shape. According to the invention, cylindrical or spherical shapes are preferred. In particular, according to the considerations of the invention, it is also possible to use housings with a spherical interior space in the area containing the cosmetics, since even cosmetics, which are viscous, can in fact be increased in size by means of a spherical configuration Take out cosmetics in the inner space.

According to the invention, the holder is preferably threaded. This configuration is particularly advantageous when the applicator is removably but still hermetically sealed on the housing.

Various materials are suitable for the housing. Preferably said material comprises a thermoplastic material, especially polyethylene, polypropylene, PVC, polyamide, PET and ABS.

In particular, when a plastic material is used, the housing is preferably produced by blow molding or injection blow molding. That would result in particularly low manufacturing costs.

Description of drawings

The invention is described in more detail below by way of examples of preferred embodiments with reference to the accompanying drawings.

Figure 1 is a schematic cross-sectional view of an applicator with a housing according to a first embodiment of the invention; and

Fig. 2 is a schematic sectional view with a housing according to a second embodiment of the invention.

Detailed ways

FIG. 1 shows a first housing 10 with a housing sleeve 12 and a retaining region 14 on which an external thread 16 is arranged. Between the retaining area 14 and the housing sleeve 12 is provided a bellows portion 18 with four outwardly projecting portions each having an angular cross-sectional shape, one of which For example, it is represented by the reference number 20. The bellows is partly surrounded by a flexible shrink tube 22 whose color corresponds to the color of the cosmetic product to be filled in the first housing, that is to say black for example for black mascara.

The applicator 24 comprises a POM with a brush-shaped working area 26 , the free end of which is held in a holding area 28 of the second housing 30 . The housing sleeve 32 of the second housing 30 has an internal thread 34 for matching with the external thread 16 of the first housing. The housing sleeve 32 extends around a receiving space 36 for the applicator 24 . Instead of said brushes, flocked foam or sharper brushes can also be provided.

In the same way, the housing sleeve 12 extends around the receiving space 38 , which is delimited on the other hand by the bottom 40 of the first housing 10 . Meanwhile, the receiving space 38 serves as a reservoir for cosmetics (not shown) having a higher viscosity.

The working area 26 of the applicator 24 is located in an area close to the bottom of the first housing 10 when the applicator 24 is pushed into the first housing so that the threads 16 and 34 are screwed together. In this case, the holding area 14 serves to hold the applicator 24 . If in this operating position the holding area 28 of the second housing 30 and the holding area 14 of the first housing 10 are towards the left in FIG. (transverse to the longitudinal axis 44 of the body 12), which is easily achieved by the flexibility of the bellows part 18, and the working area 26 is close to the housing sleeve 12 of the first housing 10 on the right side of FIG. 1, so that it can be removed Cosmetics located near the inner wall of the housing sleeve 12. In this way, the cosmetic material located in the bottom right corner of the housing sleeve 12 in FIG. It should be understood that the same applies to the other regions of the interior space 38 of the housing sleeve 12 .

Thus, it is possible to remove considerably more cosmetic product from the inner space 38 of the housing sleeve 12 by means of the working area 26 of the applicator 24 compared to a rigid connection of the holding area 14 to the housing sleeve 12, thereby greatly improving the available outflow.

The housing 10' shown in FIG. 2 differs from the first housing 10 shown in FIG. 1 only in that the bellows portion 18 is replaced by an annular disc 42 made of an elastomeric material such as rubber. The annular disc is glued or fused to the housing sleeve 12 and the retaining area 14 . Thus, as with the arrangement shown in FIG. 1 , the retaining region 14 is pivotable relative to the housing sleeve 10 towards the left in FIG. 2 so that the left-hand portion of the annular disk 42 is compressed and the right-hand portion is extended. Thus, the working area 26 of the applicator 24 located in the first housing 10' is displaced into the bottom right corner of the housing sleeve 12, where it can remove cosmetics, even if the cosmetics have a high viscosity.

Although not shown in the figures, there are further alternatives for the shrink tube 22 .

For example, instead of a shrink tube, a ring can be used which comprises an injection molded or extruded soft elastic plastic material which is previously pushed onto the mounting tube before being filled with cosmetics and then Pushed onto the holding area 14.

Alternatively, the ring can also be applied to the bellows part 18 under reduced pressure in an additional injection molding or casting operation. In this case, soft flexible plastic materials such as silicon can also be used in other constructions.

Finally, instead of the shrink tube 22 , it is also possible to use a slotted ring or an open circular part with overlapping ends, including a thermoplastic material.

Thermoplastic materials, in particular PET, PVC, nylon, polyamide and polyester, are considered materials for the housing sleeves 12 and 32 , the retaining areas 14 and 28 and the bellows portion 18 as shown. These materials are equally applicable to the applicator 24 . In particular the first housing 10 comprising the corrugated portion 18 and the retaining area 14 is easiest to manufacture by blow moulding.

The two first housings 10 and 10' shown in the figures are cylindrical. However, considering the invention, especially the bellows portion 18 and the annular disc 42, they could also be spherical or conical in shape without negatively affecting the outflow.

The features of the invention disclosed in the preceding description, the claims and the drawings can be present both individually and in combination in order to implement the invention in various embodiments.
