Abstract

L'invention concerne un récipient à capuchon vissé, qui est obtenu à partir d'un corps de récipient et d'un capuchon vissé, et qui est caractérisé en ce que : la circonférence externe de l'embout du corps de récipient comprend des sections de filetage inclinées à visser conjointement avec le capuchon vissé ; les sections de filetage inclinées comportent des saillies de filetage supérieures disposées au niveau de trois sites ou plus à des intervalles égaux lorsque l'on regarde depuis la surface supérieure, des saillies de filetage longues inférieures pour lesquelles les positions des extrémités gauches depuis les saillies de filetage supérieures sont les mêmes et s'étendent parallèlement au-dessous de ces dernières séparées d'une hauteur spécifiée et qui sont plus longues que les saillies de filetage supérieures, et des saillies de filetage inclinées qui s'inclinent vers le haut et vers la droite depuis l'extrémité droite d'une saillie de filetage longue inférieure et se raccordent à l'extrémité gauche de la saillie de filetage supérieure vers la droite ; le capuchon vissé comprend une paroi supérieure et une paroi circonférentielle suspendue depuis le bord de la paroi supérieure ; et la circonférence interne de la paroi circonférentielle comprend des saillies de filetage de capuchon, qui sont disposées à des intervalles égaux avec la même hauteur et dans le même nombre que les saillies de filetage supérieures et doivent être vissées conjointement avec les sections de filetage inclinées du corps de récipient.
