Patent

CA 2187915

A blow molded container of the present invention is a container formed by blow molding in which a single-layer or multi-layer parison comprising a cylindrical resin material is heated and inflated by air in a mold, wherein a bottom sealing portion formed by pinch offs of the mold has a projection projecting outwardly from the container and sunk portions formed in one of the resin layersconstituting the projection such a manner as to be buried in the other resin layer. Therefore, the bonded area between the resin layers is widened, thereby having higher bond strength and higher strength against the shearing force along the fusion bonded area

La présente invention concerne un récipient formé selon un procédé de moulage par soufflage consistant à utiliser une ébauche cylindrique en résine monocouche ou multicouche qui est gonflée à l'air pendant sa réchauffe dans un moule. La fermeture d'étanchéité du fond, formée par un pincement du moule, présente une protubérance sortant du récipient; l'une des couches de résine constituant cette protubérance recouvre l'autre couche de résine, constituant ainsi une zone de recouvrement. Grâce à ce procédé, il est possible d'accroître la force fusionnelle par augmentation de la superficie fusionnelle entre les deux couches, la zone de recouvrement accroissant la résistance au cisaillement selon un axe parallèle à la surface fusionnelle.
