The invention relates to a cosmetics container, in particular a mascara container, whose components are a container part, a container cap, a wiper, which is inserted into a container neck disposed on a container part, and an applicator, which is connected to the container cap and passes through the wiper with a brush rod provided with an applicator brush on its free end.
Cosmetics containers of the type mentioned above are commonly realised as material hybrids, which means that the cosmetics containers made of a plurality of components comprise components which consist of different materials. The cosmetics containers mentioned above are mostly made of material hybrids or material mixes made of aluminium and plastic, meaning an effective recycling presumes separating the materials in particular in the case when the respective material portion exceeds a certain range. Separating the materials is often time-consuming, in particular when separating the materials cannot be carried out economically means sacrificing the inferior or less valuable material to enable recycling the more valuable material portion. This can occur, for example, when cosmetics containers, which have aluminium and plastic components, are molten for recycling purposes so that the material is separated in this case by burning or gasifying the plastic portion.
An extensive recycling of a cosmetics container made of several components becomes possible using two different approaches, for example, the cosmetics container of the first approach being designed such that the individual components can be easily separated from each other, while the second approach strives for a plastic portion as small as possible to limit the non-recyclable portion of the cosmetics container to a minimum when sacrificing plastic material.
The object of the present invention is therefore to propose a cosmetics container which enables a simplified separation of materials.
According to the invention, material intersections are formed at least partially in the cosmetics container, whose wiper is made of a plastic material in contrast to at least one of the other previously mentioned components, between the different materials or components for separation purposes, the material intersections being realised as detachable form-fit, detachable substance-to-substance or detachable force-fit connections so that the cosmetics container according to the invention does not have to supplied to the recycling process as a whole unit, but instead the components can be separated before recycling takes place owing to the material intersections for the subsequent supply of the components to the different recycling methods or non-recyclable materials or materials which can only be recycled with great effort can be separated from the materials which are comparatively better suited for recycling. For the simplified separation of materials independently of a set of recycling problems, a joining end of the brush rod is connected to an applicator holder by means of a bayonet joint.
Independently of a set of problems regarding recycling, a bayonet joint between an applicator holder and an applicator for a cosmetics container, which is provided with an applicator and is realised as a mascara container, is advantageous as an applicator can be easily exchanged. This advantage of course exists independently of whether the components of the container are made of different or the same material. In the case of a mascara container, the wiper can therefore be made of any arbitrary material, as long as the wiper fulfils its function. The wiper can be made not only of plastic but also of a material deviating from the material used for the other components.
It is particularly advantageous if the wiper is made of a plastic material in deviation from one of the other previously mentioned components.
The cosmetics container according to the invention also makes it possible to reduce the plastic portion to a range as small possible, e.g., less than 10%, and to choose a uniform recycling method for the other components, in particular in the case when these materials consist of a uniform material, such as in particular aluminium.
In any case, the cosmetics container according to the invention consequently also simplifies recycling the cosmetics container.
It is particularly advantageous if the container cap comprises a cap outer part and a cap inner part, which each comprise a sleeve part, the two sleeve parts being connected to each other via a press-fit connection, an adhesive connection or a welding connection. Differentiating between a cap outer part and a cap inner part enables using different materials, if required, for the cap outer part and the cap inner part while also forming a suitable detachable material intersection between the sleeve parts to enable an overall high portion of a recyclable material of the container cap.
If the applicator is held in the cap inner part by means of the applicator holder, an intersection, which enables separating the applicator from the container cap or the cap inner part particularly easily, can be defined by the applicator holder.
Preferably, the applicator holder comprises a connective or joining area for being connected to the cap inner part so that separating the applicator holder and the cap inner part is also possible.
Preferably for this purpose, the applicator holder comprises a cup-shaped receiving part for receiving the joining end having a connective protrusion formed on a cup bottom, such that a projection of the connective protrusion, which protrudes over an opening edge of a receiving opening formed in the cap bottom of the cap inner part, engages behind the opening edge after deformation in order to be connected to the cap inner part, so that a formation can take place via an ultrasonic welding process, with the result that for separating the applicator holder from the cap inner part, merely the material projection needs to be separated.
If the joining end of the brush rod comprises two radially protruding pins, which are disposed at a distance a axially from a stop collar and serve for engaging in a locking groove each, the locking grooves each being formed in a cup wall of the applicator holder at a distance a to a cup edge, the bayonet joint can be realised using particularly little material.
Preferably, the stop collar simultaneously serves for the sealing abutment against an opening edge of an opening formed for passing the brush rod through the wiper, so that a separate seal need not be provided.
If the wiper comprises a stop collar in an axial end of a sleeve inserted into the container neck for the outer abutment against an opening edge of the container neck and comprises several fastening tabs, which are dispersed across the circumference of a sleeve edge on opposite axial ends of the sleeve and engage behind an inner shoulder, which is formed on the container neck, when deformed radially outward, a material connection between the wiper and the container neck which can be detached particularly easily can be realised.
Advantageous embodiments of the cosmetics container are described in further detail using the drawings.

As in particular
A wiper 436 made of plastic is inserted into thread part 433. Wiper 436 comprises a stop collar 439 on the upper axial end of a sleeve 438, which is inserted into container neck 431, for the outer abutment against an opening edge 440 of container neck 431. Stop collar 439 limits an opening 445 using an opening edge 444, opening 445 being formed for passing brush rod 411 through wiper 436. Sleeve 438 is provided with a plurality of fastening tabs 443 on its lower axial end, the fastening tabs 443 being dispersed across the circumference of a sleeve edge 442 and which engage behind shoulder 434, which is formed on container neck 431, when deformed radially outward and after wiper 436 has been inserted into container neck 431 for fixating wiper 436 in its position in container neck 431.
The deforming process for deforming fastening tab 443 can take place corresponding to the deforming process of connective protrusion 417 on applicator holder 414 by means of an ultrasonic welding tool. For this purpose, the deforming process (which is comparable to the deforming of connective protrusion 417, which takes place before cap inner part 405 is inserted into cap outer part 406) takes place before container neck 431 is inserted into container body 429.
