Description

BACKGROUND THE INVENTION

The The present invention relates to a refillable cosmetic package and / or pharmaceutical compositions and a method for Packaging a cosmetic and / or pharmaceutical composition in the refillable Packaging.

packagings for cosmetic Compositions are typically with a rigid cover which is a change prevents the internal volume of the packaging. In a sealed Packaging leads a change the internal pressure, for example an increase in internal pressure, which by closing the cover brought about becomes, or a change of the external pressure, to a pressure difference between the inside and the outside of the Packaging.

This Pressure difference has many disadvantages. For one thing, a hermetic one Sealing the packaging impaired which leads to a risk of leakage of the cosmetic composition due to an excessive internal Pressure or a contamination of the cosmetic composition due to a low internal pressure leads. In addition, a low pressure, which leads by moving the wall of the cover during opening of the cover Packaging is produced at the risk of having the cosmetic composition superseded and out of their housing. Furthermore The compression of the air tends to prevent the Packaging to work while an external not by an equivalent internal pressure balanced pressure tends to prevent opening Packaging to work. This pressure difference occurs at a container with sealed chamber on.

cosmetic Compositions based on wax and emulsions of a fatty Based materials can advantageously in a container refilled especially in the case of foundations, lipsticks, rouges or creams, by-products based on solvents, e.g. Water, volatile Silicones, alcohol or mixtures thereof are based. These product types need for your Store a package with a sealed chamber.

A another embodiment The present invention includes a method of packaging a cosmetic and / or pharmaceutical composition. The Method involves filling a refill container with a cosmetic and / or pharmaceutical composition. The Method also includes assembling the refill container, the containing the cosmetic and / or pharmaceutical composition, with the packaging. The filling can be done be while the cosmetic and / or pharmaceutical composition is warm.

Out EP-A-0845230 discloses a refillable package, those with an outer shell, an opening the base of the shell for picking up a container and a means for securing the container is provided.

The known sealed packages for cosmetic compositions have an elastomeric seal with a compression, which is a having axial component. These packages have many Disadvantage. The seal quality is only ensured if the elastomeric seal with a relative high force is compressed what the closing makes packing difficult and not very reliable. In addition, the Packaging a high price, because not only used an expensive seal but also due to difficulties of automation in the positioning of a non-rigid part, e.g. one Elastomer seal.

One Another problem with sealed cosmetic packaging concerns Refills. The production of a packaging for a cosmetic composition is known by placing a refill unit in a housing. Positioning and holding the refill unit is not always easy. Furthermore increases that Volume of the container, the the refill unit takes up the space required for the Packaging. About that It is not always easy, the temporary hermetic sealing of a sealed chamber of a refillable packaging for a cosmetic and / or pharmaceutical composition based on a volatile solvent was made to ensure.

DETAILED DESCRIPTION OF EMBODIMENTS

1 shows a packaging that has an outer shell 1 , For example, of cylindrical, at the base of elliptical, oval, polygonal or other shape, that of a cover 6 is closed. The base 45 the shell 1 is with an opening 46 for picking up the refill unit 29 provided, in particular in a crucible or a trough 10 which is capable of incorporating a cosmetic and / or pharmaceutical composition. A locking mechanism 39 , for example wise with a screw thread, a set of pins or pegs that allow locking by snapping, ensures that the crucible or the trough 10 is assembled with the packaging according to the present invention.

The packaging of 1 does not provide hermetic sealing of the refill unit 29 for sure. In particular, with this packaging there is a risk of fluid at the edges of the opening 46 between the edge of the base 45 and the wall, the crucible or the trough 10 is opposite, exit.

The use of the packaging of 2 requires several steps involving the removal of the cover 6 , removing the cover 47 , removing the desired amount of cosmetic and / or pharmaceutical composition, re-applying the cover 47 on the hollow 10 and reattaching the cover 6 on the packaging.

3 shows an example of a package that has a cover 6 which, for example, in its center with a cover 47 is provided, which ensures a temporary hermetic sealing of the crucible or the trough. Furthermore, an inventive embodiment of the cover, which in the 4 . 5 and 6 is shown, a fixing mechanism on, the pin 50 and 51 which engages the envelope of the package having corresponding grooves.

In 4 an embodiment of the packaging according to the present invention is shown, its crucible or trough 10 beyond a radially inner chamber 49 for picking up the cosmetic composition that passes through walls 50 and radially outer walls 51 for applying the cover 13 ' the cover 6 is limited. The cover 13 ' becomes the radially inner side of the radially outer wall 51 created, thus providing a temporary hermetic sealing of the chamber 49 for sure. The radially outward force coming from the cover 13 ' on the walls 51 is exercised only to a very small extent on the walls 50 transfer, which increases the risk of detachment of the cosmetic composition from the wall 50 significantly reduced. A preferred embodiment of the refill unit 29 , for example in the form of a crucible or a trough according to the present invention is in the 5 to 7 shown. It is beneficial if the crucible or the trough 10 has an undercut shape, ie when the opening 52 narrower than the ground that lies opposite. As a result, the crucible tends 10 on the one hand to retain the cosmetic composition when the box according to the present invention with the opening is turned down, and on the other hand put the narrow walls of the crucible at the opening 52 an optical masking of a possible detachment of the cosmetic composition with respect to the walls at the bottom due to evaporation of the solvent, if the box is left open for a long time, which is a frequent application error. The undercut shape of the crucible or the trough 10 for picking up the cosmetic, masking the shrinkage of this composition, which is poured warm into the crucible or trough, allows for shrinkage during the cooling phase.

The undercut trough is made by blowing or advantageously by injection molding with a mold that is opened in two steps. first the exterior of the form is loosened; then a piston ensures demolding of the crucible or trough, with elastic deformation of the plastic material forming the crucible. The attachment of the trough 10 at the bottom 25 of the box according to the present invention is carried out by a known mechanism, as for example by screwing over a quarter turn or advantageously by snapping. For example, the crucible or trough points 10 outside the walls a radially outer wall 51 on, with the securing element, for example in the form of hooks, or on the other hand with locking grooves, preferably regularly around the circumference of the wall 51 are distributed, is provided. In the illustrated example, the trough is approximately elliptical and has four securing hooks 39 at the point of intersection of the long and short axes of the ellipse with the outside of the wall 51 are arranged.

Setting the refill unit 29 through the opening 10 that in the base 45 of the box according to the present invention enables the production of packaging with a reduced footprint. In addition, the bottom of the crucible or the trough leaves 10 which advantageously extends in the extension line of the bottom of the lower part of the box according to the present invention, the latter look particularly good.

Furthermore, the crucible or the trough can be 10 especially easy to fill in an automatic filling system, preferably warm. In such a case, the trough is made of a material that is resistant to the filling temperature. The rest of the box can be made of less expensive materials.
