Definitions

  • Two-piston systems are also known. From the DE 20 2007 004 662 U1 for example, a container with two pistons is known, which are arranged one above the other and slide along the wall of the container. On the container a two-way pump is arranged. One The first way of the pump opens at the upper end of the container. The second path terminates in a conduit which traverses the first piston and slides along the same latter. The first component is in the space above the first piston while the second component is in the space between the first and second pistons. Also in this device, the risk of not promoting the two components in a sufficiently precise ratio, relatively large.
  • the object of the invention is thus to provide a delivery module containing at least a first and a second component of a cosmetic leave-on or rinse-off composition for application to the human body, which enables the components of the cosmetic composition before use if necessary, apply the components evenly and in a defined ratio to the human body.
  • the dispensing module is to prevent possible malfunction in the event of deformation of the container and allow a free choice of container shape.
  • a dispensing module of the type mentioned in which the coupling means comprise a part connecting the first piston to the second piston, wherein the first piston, the part and the second piston form a piston unit, wherein the first chamber is annular is formed and limited in its central region by the part of the piston unit and wherein the second chamber is concentric with the first chamber and arranged above it and the first piston and / or the second piston having a piston head, initially separated from the coupling means and after filling the dispensing module with the components is irreversibly connected to the coupling means.
  • the first chamber is filled with the first component of the cosmetic composition and the second chamber with the second component of the cosmetic composition.
  • the cosmetic composition consisting of at least two components, the components of which are present in separate chambers before use, can, if required, be applied uniformly and with a defined ratio of the components to the human body.
  • the dispensing module in a container with suitable dispensing means, deformation of the container no longer causes malfunction of the dispenser module.
  • the outer shape of the container can be chosen freely, making it possible to make it more user-friendly by the grip of the container and its ergonomics are improved.
  • cosmetic leave-on compositions are products which remain on the body and act there.
  • cosmetic rinse-off compositions are products which are rinsed off immediately after use or after a given exposure time.
  • the first and the second component of the cosmetic composition each have functional groups which react chemically with one another when the components are mixed. It is advantageous here that chemical reactions during storage in the delivery module are prevented, the occurrence of which is desired only when the mixture of the two components is applied. Thus, an optimal application of the mixture of components, in addition to good end product properties is possible. Such chemical reactions lead, for example, to gas release and, associated therewith, foaming of the mixture, to gel formation or else solidification of the cosmetic composition. Initiation of redox reactions is also possible by mixing the components. Color changes, the generation of haptic effects or drug release are possible desired consequences, which should occur only in the application.
  • the components can also have no functional groups which can chemically react with one another during the mixing of the components. It is advantageous that incompatible or non-storable components are mixed only during the application and thus negative effects, such as phase separations or coagulation can be avoided. In addition, when blending the components, physical effects such as changes in temperature, viscosity, color or state of aggregation, which are advantageous in use, can be caused.
  • the ratio of the volumes of the first and the second component is in the range between 20: 1 to 1:20, preferably between 10: 1 and 1:10 and particularly preferably between 5: 1 and 1: 5.
  • a defined ratio of the volumes can be determined by the appropriate choice of the base areas of the pistons of the delivery module realize.
