Title
(EN) THERMOPLASTIC COMPOSITE LAYERED SQUEEZE TUBE AND METHOD OF MAKING SAME
(FR) TUBE THERMOPLASTIQUE SOUPLE, STRATIFIE ET COMPOSITE, ET PROCEDE DE FABRICATION
Abstract
(EN)
A thermoplastic tube (1), and method for forming such a tube, has a tube body portion formed from an inner layer (15) of thermoplastic material, a barrier layer (21), and an outer layer (25) of thermoplastic material. The outer layer does not extend completely about the periphery of the tube body and a strip (15) of thermoplastic material having the same composition as the inner layer, fills each gap in the outer layer to form a smooth surface about the tube. The strip may be transparent or of a color different than the color of the outer layer. In a preferred tube, a first layer (19) of adhesive material is provided between the inner layer and the barrier layer, and a second layer (23) of adhesive material is provided between the barrier layer and the outer layer and strip.
(FR)
Tube thermoplastique (1) et procédé de fabrication. Le tube comprend une partie corps composée d'une couche interne (15) d'un matériau thermoplastique, d'une couche d'arrêt (21) et d'une couche externe (25) d'un matériau thermoplastique. La couche externe ne s'étend pas entièrement autour de la circonférence du corps du tube, et une bande (15) d'un matériau thermoplastique, ayant la même composition que la couche interne, remplit chaque vide de la couche externe pour former une surface lisse autour du tube. La bande peut être transparente ou d'une couleur différente de celle de la couche externe. Selon un mode préféré de réalisation, une première couche (19) d'un matériau adhésif est placée entre la couche interne et la couche d'arrêt, et une seconde couche (23) d'un matériau adhésif est prévue entre la couche d'arrêt et la couche externe et la bande.
