Abstract

Compressible tube comprises a laminated inner tube consisting of >=1 synthetic resin forming a thin wall highly resistant to oil and water and a low permeability to oxygen, water vapour and odours. An outer protective tube consists of synthetic resin having sufficient elasticity to recover its original shape after being compressed. The two tubes are closed at their lower ends, and fixed to the neck of the tube body at their upper ends so that the neck opening, to which is removably attached a closure device, communicates only with the interior of the inner tube. The laminated resin comprises a layer of ethylene-vinyl alcohol copolymer, and two layers of polyethylene disposed on both sides of the first layer.

Description

       

  
 



   La présente invention a pour objet un tube pressable, tel qu'il est décrit dans le brevet principal   N"    561639.



   Selon la revendication du brevet principal, le tube pressable est caractérisé en ce qu'il est à paroi double et comprend un corps muni d'un col, et un organe de fermeture agencé pour pouvoir être fixé de façon amovible au col, en ce que le corps est pourvu d'un tube intérieur en couches laminées comprenant au moins une résine synthétique formant une paroi mince, cette paroi étant hautement résistante à l'huile et à l'eau et présentant une perméabilité très faible à l'oxygène, à la vapeur d'eau et aux odeurs, et un tube extérieur entourant le tube intérieur pour le protéger et constitué en résine synthétique d'élasticité suffisante pour permettre au tube extérieur de reprendre sa forme primitive après qu'il a été pressé, les tubes intérieur et extérieur étant fermés à leur extrémité constituant le fond et fixés au col à leur extrémité opposée,

   de manière que l'orifice du col ne communique qu'avec l'intérieur du tube intérieur.



   Dans une forme d'exécution particulière de ce tube les couches laminées comprennent une couche en alcool de polyvinyle.



   On a trouvé que   l'on    pouvait remplacer la couche d'alcool de polyvinyle utilisée dans le laminé de résine synthétique par un copolymère de l'alcool vinylique. Ce copolymère d'alcool de vinyle a l'avantage par rapport à l'alcool de polyvinyle d'être insoluble à l'eau. Un tube pressable comprenant une couche de ce copolymère possède une résistance accrue à l'eau.

 

   Le tube selon la présente invention est caractérisé en ce que les couches laminées comprennent une couche de copolymère d'alcool de vinyle et d'éthylène et deux couches en polyéthylène déposées sur l'ensemble des faces de la première couche.



   REVENDICATION

   The present invention relates to a squeezable tube, as described in main patent No. 561639.



   According to the claim of the main patent, the squeezable tube is characterized in that it has a double wall and comprises a body provided with a neck, and a closure member arranged to be able to be removably attached to the neck, in that the body is provided with an inner tube in laminated layers comprising at least one synthetic resin forming a thin wall, this wall being highly resistant to oil and water and having very low permeability to oxygen, water. water vapor and odor, and an outer tube surrounding the inner tube to protect it and made of synthetic resin of sufficient elasticity to allow the outer tube to return to its original shape after it has been pressed, the inner tubes and exterior being closed at their end constituting the bottom and attached to the neck at their opposite end,

   so that the orifice of the neck communicates only with the interior of the inner tube.



   In a particular embodiment of this tube, the laminated layers comprise a layer of polyvinyl alcohol.



   It has been found that the polyvinyl alcohol layer used in the synthetic resin laminate can be replaced by a copolymer of vinyl alcohol. This vinyl alcohol copolymer has the advantage over polyvinyl alcohol of being insoluble in water. A squeezable tube comprising a layer of this copolymer has increased water resistance.

 

   The tube according to the present invention is characterized in that the laminated layers comprise a layer of vinyl alcohol and ethylene copolymer and two polyethylene layers deposited on all of the faces of the first layer.



   CLAIM



   Squeezable tube according to the claim of the main patent, characterized in that the laminated layers comprise a layer of vinyl alcohol and ethylene copolymer and two polyethylene layers deposited on all the faces of the first layer.
