Definitions

  • the invention relates to a package having a substantially dimensionally stable, while elastically deformable outer container, an arranged therein, easily deformable, the filling receiving inner bag and a valve, through the opening of filling material is discharged when pressure is exerted on the outer container.
  • This is a so-called airless system, in which after delivery of contents no air enters the inner bag, but it enters air from the outside atmosphere in the space between the outer container and the inner bag, wherein the inner bag is increasingly pressed together and remains in this state until the entire contents have leaked out of the packaging, also referred to as a squeeze bottle.
  • DE 102 177655 discloses a packaging in which the valve has a membrane with a sleeve-shaped projection which surrounds a journal of a base body extending over the opening of the outer container, the filling material passing between the sleeve and the journal through to the outlet opening of one Cap passes. If this package is used for liquid product, it may happen that the sleeve-shaped portion of the membrane in the discharge of contents in places adheres to the pin of the base body, with the result that the liquid jet when squeezing the outer container is not in the longitudinal direction of the outer container, but in one

  • the contents if it is a liquid, in the longitudinal direction of the outlet opening in a rectilinear beam from the opening, the bore of which is aligned with the longitudinal axis of the outer container, since the liquid located in the receiving space unhindered by the jammed from the outlet pin gets into the outlet opening.

  • the vent valve is tightly closed upon squeezing (squeezing) of the outer container due to the increased pressure in the air space, so that no air can escape from the air space.
  • the exerted pressure force on the outer container is thus fully exerted on the contents, which emerges in the manner described above from the outlet opening of the valve.
  • the vent valve opens by the negative pressure until the pressure equalization is done.

Abstract

L'invention concerne un emballage présentant un contenant extérieur élastiquement déformable et sensiblement stable dimensionnellement dans lequel est disposé un sachet intérieur facilement déformable recevant la matière de remplissage, ainsi qu'une soupape. Cet emballage est caractérisé en ce que la soupape comprend : un corps de base s'étendant par-dessus l'ouverture du contenant extérieur, ce corps de base présentant au moins une ouverture de passage pour la matière de remplissage et un axe dirigé à l'opposé du contenant extérieur; ainsi qu'un capuchon fixé sur le col du contenant extérieur et recouvrant le corps de base, la paroi de fermeture supérieure de ce capuchon étant formée par une membrane qui délimite un espace de réception pour la matière de remplissage entre le capuchon et le corps de base et présente une ouverture de sortie pour la matière de remplissage. Lorsque l'emballage n'est pas soumis à une pression, ladite ouverture de sortie est fermée par l'axe, la zone de la membrane contenant l'ouverture de sortie étant appliquée contre l'axe par précontrainte. Lorsqu'une pression est exercée sur le contenant extérieur, la membrane est soulevée de l'axe par la matière de remplissage sous pression se trouvant dans l'espace de réception, de sorte que de la matière de remplissage peut sortir. L'emballage selon l'invention se caractérise également en ce que le capuchon présente un espace rempli d'air séparé de l'espace de réception pour la matière de remplissage et rendu étanche par rapport à l'espace de réception et au contenant extérieur, cet espace rempli d'air communiquant avec l'espace intermédiaire entre le contenant extérieur et le sachet intérieur par au moins un trou ménagé à travers la paroi du contenant extérieur et avec l'atmosphère extérieure par au moins une soupape d'aération.
