Abstract
L'invention concerne une butée d'extrémité (134) pour sac thermoplastique (120) doté d'une fermeture refermable (121) au niveau de l'extrémité supérieure ouverte dudit sac. Cette fermeture refermable (121) comprend deux bandes de fixation (130, 131) qui s'interverrouillent. La butée d'extrémité (134) est configurée de façon à faciliter un positionnement par encliquetage sur les bandes de fixation (130, 131), et comprend une partie supérieure et deux parties latérales (172, 174) dépendantes qui chevauchent la fermeture (121). Les parties latérales (172, 174) comprennent également une patte orientée vers l'intérieur, et une structure d'épaulement (198, 202) qui coopère avec la fermeture refermable et empêche que la butée d'extrémité soit retirée par inadvertance dans un sens transversal de façon à la maintenir en place avant sa liaison au sac. L'étape de liaison s'effectue de préférence par soudage par ultrasons. Dans le cas d'une production linéaire de sacs thermoplastiques, dans laquelle une bande continue de matériau de plastique se déplace d'une station à la suivante, cette invention permet de positionner la butée d'extrémité sur la fermeture refermable au niveau d'une première station, et de relier ladite butée d'extrémité au sac au niveau d'une seconde station. Les étapes de positionnement et de liaison peuvent s'effectuer simultanément.
