CA 2200803

This invention includes a procedure to manufacture preforms with integrated handles, preforms, and containers that are achieved with them. The injection mold (1) incorporates a lateral upper ridge (2) at a tangent and in proximity to its own mouth, as well as a single distributor (7) for the refrigerant fluid, with concentric rings or channels (8) joined to other connecting channels (9), at intervals between levels, in such a way as to arrange these second vertical channels (9) between each grouping of two of these, and placing the one from the previous level and the next one 180 degrees from it, incorporating the integrated handle (3), laminate, a groove (5) in the area closest to the neck, opposite the ridge (2) of the mold (1), which delineates an elastic cut-off.

L'invention a trait à un procédé de fabrication de préformes à poignée intégrée, d'autres types de préformes et de contenants à partir de ces préformes. Le moule à injection (1) comporte une crête latérale supérieure (2) en tangente et à proximité de son entrée, ainsi qu'un distributeur unique (7) de liquide refroidisseur à anneaux ou canaux concentriques (8) reliés à intervalles entre les niveaux à d'autres canaux de communication (9), de manière à aménager ces deuxièmes canaux verticaux (9) entre chaque groupe de deux ou de trois, et à placer celui du niveau précédent et le prochain à 180 degrés de ce point, incorporant la poignée intégrée (3), le laminé et une rainure (5) dans la partie la plus proche de l'ouverture opposée à la crête (2) du moule (1), qui délimite une surface d'appui élastique.
