Definitions

  • the present invention relates to a tap used as a practicable closing means for packaging materialized in plastic bags housed inside a cardboard box and those with an automatic closing system.
  • the object of the invention is to achieve a structurally simple, consequently economical tap, which also offers an optimal barrier effect both against environmental oxygen and other gases, reducing their access to the interior of the container as much as possible, as against the tendency at the exit of the interior of the container of the aromas and other gases that tend to detach from the product contained therein.

  • the extraction of the wine implies a parallel deformation of the bag, with reduction of its effective volume, so that throughout the consumption of its content no air enters the bag, and consequently the wine also does not come into contact with the oxygen.
  • bag-type containers are provided with a rigid neck, which is generally attached to the bag itself by heat welding, and so that said rigid neck configures a kind of bushing in which a tap or valve that allows the controlled dispensing of the content, when necessary.
  • Manual taps have as a fundamental problem their complexity of handling, especially due to the need to use two hands for the opening and closing maneuvers of the same, but in return they generally offer greater structural simplicity, since some of them are constituted by less pieces, in front of four, five and even

  • SUBSTITUTE SHEET (RULE 26) This position can be called transport since it will be maintained until the moment in which the dispensation begins for what is necessary to break and then detach the aforementioned seal, an act that will allow axial displacement until the respective neck and tap gates enter in contact, position that will give way to the contents inside the tap and consequently to the outside of the bag by opening it. This position is reversible at the will of the user, if he intended a prolonged storage after consumption began.

  • the impermeability of the neck-tap assembly is important, since the insulation of the contents with the outside is maximum, mostly with double wall between content and outside, which is of special interest if it is taken into account that in the manufacture of these taps the polyethylene is totally or partially involved, which, as is known, is quite permeable to

Abstract

L'invention concerne un robinet du type comprenant un col (1) fixé à un sachet en plastique (3), le corps (7) du robinet étant fermé par son extrémité inférieure (9) et comprenant des orifices de communication avec l'intérieur du sachet positionnés de manière latérale, ledit robinet pouvant être actionné par déplacement axial du corps (7) par rapport au col (1). Le corps (7) comprend une ouverture latérale (14) dans sa partie supérieure externe, face à laquelle est positionné un obturateur (15) monté solidaire avec une membrane (18) élastiquement déformable, fixée à l'extrémité supérieure libre du corps (7) et qui est pourvue d'une fenêtre latérale (16) pouvant être positionnée en face ou à côté de l'ouverture (14), en fonction des positions d'ouverture et de fermeture du robinet. Un robinet à fermeture automatique peut ainsi être obtenu, ledit robinet ne comptant que trois pièces, notamment le col, ce qui permet de réaliser un gain sensible en matière de coût, et d'améliorer considérablement les performances en matière de sécurité et d'étanchéité en ce qui concerne l'entrée d'oxygène, de gaz et la perte de saveurs.
