Patent

CA 2617220

The invention relates to bringing a parison or a preform into contact with the body-molding surface of a split mold in such a way that the earliest contact of the parison or the preform with the molding surface occurs at a prescribed lengthwise position and thereby inhibiting the formation of air bubbles between the in-mold label and the container body formed from the parison or preform. In producing a container (1) comprising a body (4) and an in-mold label (7) covering the whole outer periphery of the body (4), a ring section (4a) having the minimum wall thickness which comes earliest into contact with the body-molding surface (14) of a split mold (13) is formed in the step of forming a parison or preform into the body (4) to inhibit the formation of air bubbles between the body (4) and the in-mold label (7) covering the whole outer periphery of the body (4).

Cette invention concerne la mise en contact d~une paraison ou d~une préforme avec une surface de moulage de corps d~un moule fendu de manière à ce que le premier contact de la paraison ou de la préforme avec la surface de moulage se produise à une position de longueur définie, empêchant ainsi la formation de bulles d~air entre l~étiquette moulée et le corps de récipient obtenu à partir de la paraison ou de la préforme. En produisant un récipient (1) comprenant un corps (4) et une étiquette moulée (7) couvrant toute la périphérie externe du corps (4), une section anneau (4a), possédant une épaisseur de paroi minimale qui vient au premier contact de la surface de moulage de corps (14) d~un moule fendu (13), est formée lors de l~étape consistant à former une paraison ou une préforme dans le corps (4) afin d~inhiber la formation de bulles d~air entre le corps (4) et l~étiquette moulée(7) couvrant toute la périphérie du corps (4).
