Definitions

  • the invention relates to a single-use container for mixing and removing two components contained therein with an internal membrane which divides the container into two chambers in which the separate components are located.
  • Certain products such as Hair colors or glue consist of two components, which must be stored separately and only mixed with each other immediately before use.
  • the components in two individual packs are mixed by transferring the component of one pack to the component of the other pack, the pack of the second component of course having a sufficient volume to accommodate both components and, if appropriate, an additional free volume for relief of the mixing process.
  • a pressure-free container of the type mentioned at the outset is known in which the individual components are separated from one another by an aluminum foil.
  • the film acting as a membrane breaks through a molded piece which is coupled to the flexibly designed bottom and is actuated by finger pressure, so that the components can get from one chamber to the other, the mixing taking place.
  • the mixture is also applied by finger pressure on the flexible floor.
  • Such containers have the disadvantage that a flange projecting from the outside of the container is required to attach the membrane, which is intended for the user of such containers creates an optically unattractive impression and, in addition, increases the volume of the usually existing wrapping packaging of the container for mixing in an uneconomical manner.
  • the object of the present invention is to remedy this disadvantage and to expediently replace the separation of the membrane caused by movable mechanical means.
  • the object is achieved by a container which is distinguished by the wording of claim 1.
  • Advantageous developments of the container according to the invention are characterized by the features of claims 2 to 8.
  • the container 10 contains a cup-shaped membrane 20, which is provided on the side facing the inner wall 11 of the container 10 with an adhesive seam 21 and is fastened to the inner wall 11 of the container 10, whereby two chambers 30, 31 are formed, a valve 12 and optionally a plug 13 on the bottom for filling the chamber 31 with a component and compressed gas.
  • the other chamber 30 is filled with compressed gas via the valve 12 after the other component has been introduced.
  • the excess pressure of the first chamber 30 is reduced to such an extent that the membrane 20 is peeled off by the force of the pressure now acting in reverse, for example at its adhesive seam 21, or is torn open at a weakened zone 25 which acts as a predetermined breaking point.
  • FIG. 2 shows in the left part a container 10 with a predetermined breaking point as a weakened zone 25 in the open state and in the right part ⁇ in the opened state.
  • the container To open the membrane 20 at the predetermined breaking point, the container must be turned upside down before actuating the valve 12; i.e. chamber 30 must be at the bottom, chamber 31 at the top.
  • the valve 12 When the valve 12 is actuated, the pressure in the chamber 31 is reduced so much that the membrane 20 can no longer withstand the pressure in the chamber 30 and tears at the predetermined breaking point.
  • the product with the pressure medium can be discharged via the valve 12.
  • the valve 12 is directed downwards in the arrangement according to FIG. 1 and upwards in the arrangement according to FIG.

Abstract

Un récipient (10) à usage unique de mélange et de distribution de deux composants qui y sont contenus comprend une membrane (20) agencée à son intérieur qui divise le récipient en deux chambres (30, 31) dans lesquelles sont contenus les composants séparés. Il faut pour assujettir cette membrane (20) une bride dépassant de la paroi du récipient (10), dont l'aspect est peu esthétique et qui augmente en outre le volume de l'emballage et le rend plus coûteux. Pour éviter cet inconvénient, un récipient (10) sous forme d'emballage pressurisé à soupape de distribution (12) comprend une membrane (20) assujettie de manière étanche à l'intérieur du récipient (10) et conçue de telle manière qu'une force déclenchée par une pression différentielle introduite dans les chambres (30, 31) ouvre la membrane (20).

Claims (8)

  1. Récipient (10) destiné à un usage unique pour le mélange et le prélèvement de deux composants qu'il contient, comportant une membrane (20), disposée à l'intérieur, qui divise le récipient (10) en deux chambres (30, 31) dans lesquelles se trouvent les composants séparés, le récipient (10) étant un emballage sous pression de gaz muni d'une valve de prélèvement (12) et la membrane (20) étant fixée de manière étanche au récipient (10) à l'intérieur de celui-ci, caractérisé en ce que la membrane est agencée de telle manière qu'une force provoquée par une différence de pression de gaz suscitée dans les chambres (30, 31) ouvre la membrane (20).
  2. Récipient (10) selon la revendication 1, caractérisé en ce que la membrane (20) est sous forme de pot et est collée de manière annulaire à la paroi interne (11) du récipient (10).
  3. Récipient (10) selon la revendication 2, caractérisé en ce que la différence de pression ouvre la membrane (20) par décollement et/ou retournement de la partie de la membrane (20) qui est située au niveau de la paroi interne (11) du récipient (10) et le composant d'une chambre (30) peut parvenir jusqu'au composant de l'autre chambre (31).
  4. Récipient (10) selon la revendication 1 ou 2, caractérisé en ce que la différence de pression ouvre la membrane (20) par une rupture voulue au niveau d'une zone affaiblie (25) de la membrane (20) et le composant d'une chambre (30) peut parvenir jusqu'au composant de l'autre chambre (31).
  5. Récipient (10) selon la revendication 1 ou 2, caractérisé en ce que la différence de pression pousse le fond (22) de la membrane (20) contre une butée de sorte que la membrane (20) s'ouvre et le composant d'une chambre (30) peut parvenir jusqu'au composant de l'autre chambre (31).
  6. Récipient (10) selon l'une des revendications 1 à 5, caractérisé en ce que la membrane (20) consiste d'une manière connue en soi en métal.
  7. Récipient (10) selon l'une des revendications 1 à 5, caractérisé en ce que la membrane (20) consiste en matière plastique, ou en un matériau composite matière plastique-matière plastique ou métal-matière plastique.
  8. Récipient (10) selon l'une des revendications 1 à 7, caractérisé en ce qu'il présente un resserrement (14) dans le domaine de la fixation de la membrane (20).
