Title (EN) DISPENSING CLOSURE SEALS
(FR) JOINTS DE FERMETURE DE DISTRIBUTION
Abstract: front page image
(EN)Sealing structure to be utilized within dispensing closures having polyolefin parts and having a rotating spout. In the past due to manufacturing difficulties, such as shrinkage, rotating closures made from polyolefin tended to leak. The seal of the invention can be created using an edge (40) on an external surface (42) of the cap (12) to engage an end (36) of the spout (14). This edge serves to create a seal. The end (36) of the spout (14) and the external surface (42) adjacent to the edge (40) have related cross-sectional configurations such that in all positions of the spout (14) the end (36) engages the edge (40) in the same manner to form the seal.
(FR)Structure d'etancheite utilisee dans des fermetures de distribution ayant des pieces en polyolefines et ayant un bec tournant. Dans le passe, a cause des difficultes de fabrication, telles que le retrait, les fermetures rotatives fabriquees a partir de polyolefines avaient tendance a fuir. Le present joint peut etre fabrique en utilisant un bord (40) sur une surface externe (42) du couvercle (12) pour engager une extremite (36) du bec (14). Ce bord sert a former un joint. L'extremite (36) du bec (14) et la surface externe (42) adjacente au bord (40) ont des configurations de section en rapport mutuel de telle sorte que dans toutes les positions du bec (14), l'extremite (36) engage le bord (40) de la meme maniere pour former le joint.
