Abstract

Selon l'invention, une épaisseur d'un point de fusion entre un élément de couvercle et une partie de bride d'un récipient à bride est rendue plus uniforme. A cet effet, l'invention porte sur un dispositif de thermoscellage, lequel dispositif comporte un élément de support (10) et un corps de fusion (30). L'élément de support (10) soutient un récipient à bride (100). Le récipient à bride (100) comporte une partie de réception d'objet (110) et une partie de bride annulaire (112). La partie de réception d'objet (110) a une embouchure (120). La partie de bride (112) est disposée au niveau d'une marge de l'embouchure (120). Le corps de fusion (30) presse un élément de couvercle (102) contre la partie de bride (112). Le corps de fusion (30) fusionne l'élément de couvercle (102) avec la partie de bride (112). L'élément de support (10) présente une partie de formation de trou traversant (20). La partie de formation de trou traversant (20) forme un trou traversant (150). La partie de réception d'objet (110) pénètre dans le trou traversant (150). La partie de bride (112) se retrouve accrochée sur la partie de formation de trou traversant (20). Après correction de la partie de bride (112) sous une forme plus proche d'une forme annulaire plate, le corps de fusion (30) fusionne l'élément de couvercle (102) avec la partie de bride (112).
