  • Both chambers have outlet openings in a mixing area, wherein the components are retained in the chambers unmixed by separating films before use.
  • To express the components of the container is compressed in the region of the chambers, so that the release films break open and get the two components in the mixing area.
  • integrally formed deflecting elements are arranged on the container foils, by means of which the two components are mixed together.
  • the mixing area is followed by a discharge area with an outlet opening for the component application.

Due to the limited embodiments of such a mixer very long flow paths of the components to be mixed are also required to achieve a sufficient mix, resulting in a high Auspresswiderstand. In addition, the deflection elements are tuned to certain components and applications and can not be easily changed.
  • Object of the present invention is to provide a multi-component film container and a container assembly of the type mentioned, which are easy to prepare and allow a particularly effective mixing of different components. Further, the invention is intended to provide a squeezing device for the multi-component film container which permits effective mixing of the components.

Due to the separate mixing element, the multi-component film container can also be adapted relatively easily to different needs and components. Depending on the nature and properties of the components, a suitable mixer can be selected either already during production or even before use without major changes in production technology.
  • the chambers are formed in two half-shells, which are made of a flexible, yet dimensionally stable material.
  • the two half shells can be easily filled and then assembled.
  • the dimensionally stable material can prevent the chambers from bulging during the squeezing process, so that the entire pressure applied for squeezing the components out of the chambers into the discharge channel is available.

Abstract

L'invention concerne un contenant en feuilles à plusieurs constituants, qui présente un premier compartiment (5) destiné à recevoir un premier constituant, au moins un deuxième compartiment (5') destiné à recevoir un deuxième constituant, un canal de décharge (6) pouvant être relié aux compartiments (5, 5'), des éléments déflecteurs (11) destinés à mélanger les constituants à l'intérieur du canal de décharge (6) ainsi qu'un scellement (12 ; 12' ; 21 ; 25, 25' ; 36, 36') empêchant un mélange des constituants avant utilisation et pouvant être ouvert pour la décharge des constituants. Selon la présente invention, les éléments déflecteurs (11) du contenant en feuilles à plusieurs constituants sont placés sur un élément mélangeur séparé (9) placé dans le canal de décharge (6), de sorte que ce contenant en feuilles à plusieurs constituants peut être réalisé de manière simple et permet un mélange particulièrement efficace de différents constituants. Cette invention concerne également un dispositif de pression permettant une pression particulièrement efficace d'un contenant en feuilles à plusieurs constituants. Selon ladite invention, ce dispositif de pression présente un élément de maintien (61 ; 77) destiné à recevoir un contenant en feuilles à plusieurs constituants, au moins une branche (68, 69 ; 88), pouvant être déplacée en direction des compartiments (5, 5') du contenant en feuilles à plusieurs constituants pour presser ledit contenant, étant articulée sur l'extrémité de l'élément de maintien faisant face à l'extrémité arrière d'un contenant en feuilles à plusieurs constituants inséré, ce qui permet d'obtenir un mélange efficace des constituants.
