There are various ways to latch a closure onto a container. It has been found that for blowmolded containers (30) that the support flange (36) for the bottle preform can later be used as a part of the latch mechanism (14) to secure a closure (10) onto the container. Preforms have a support flange by which the preform is handled prior to being placed into the mold and in the mold. Prior to being placed in the mold, the preform is heated to about 85 ~C to about 200 ~C. During this time and in the mold, it will be supported by the support flange. This support flange is used after the container is blown and filled as one part of the latching mechanism of the closure. The closure will have a portion that is an interference fit with the support flange of the bottle to thereby secure the closure to the bottle.

Il existe diverses façons de verrouiller une fermeture sur un conteneur. On a découvert que pour des conteneurs moulés par soufflage le rebord support destiné à la préforme de la bouteille peut ensuite être utilisé comme partie du mécanisme de verrouillage afin de sécuriser une fermeture sur le conteneur. Les préformes possèdent un rebord support par le biais duquel la préforme est manutentionnée avant d'être placée dans le moule. Avant d'être placé dans le moule, la préforme est chauffée à environ 85 ·C jusqu'à environ 200 C. Pendant ce temps et dans le moule, elle va être supportée par le rebord support. Ce rebord support est utilisé après le soufflage du conteneur et rempli comme une partie du mécanisme de verrouillage de la fermeture. La fermeture présentera une partie consistant en un ajustement serré avec le rebord support de la bouteille afin de sécuriser la fermeture sur la bouteille.
