There is. Furthermore, a plurality of guiding ribs 31 extending downward from the ridges 12a are formed in the circumferential direction, and the lower part of the guiding ribs 31 has a smaller diameter toward the top and the mouth of the container 2 when the hinge cap 41 is plugged.

  • thick buckling prevention ribs 32 are provided on the inner surface of the outer peripheral surface 21 of the upper lid 6 in a plurality of places in the circumferential direction. According to this configuration, when the plugging is carried out, pressing force is applied from the jig for plugging to the upper lid 6, but the force at that time passes through the buckling preventing rib 32 and the upper surface of the main body 4 (specifically, It can be well transmitted to the upper surface of the outer cylinder 12). Therefore, when the upper lid 6 is deformed to a buckling state at the time of tapping, the force may be concentrated at a portion to be fractured for recycling (the longitudinal groove 33, the circumferential groove 34, etc.) of the main body 4 and the fracture may occur. However, such a problem can be prevented, and the hinge cap 41 can be mounted on the mouth 3 of the container 2 well.

Abstract

L'invention concerne un capuchon à charnière (1) comprenant un corps (4) destiné à être fixé à l'ouverture d'un récipient, et un couvercle supérieur (6) rattaché au corps (4) par l'intermédiaire d'une charnière (5). Une section ouvrable (18) qui, lorsqu'elle est ouverte, devient une ouverture (17) pour la libération du contenu, équipe le corps (4). Dans une vue en plan, la section ouvrable (18) a la forme d'une goutte dans laquelle, dans la région à ouvrir, la zone située du côté opposé à la charnière (5) présente une petite largeur d'ouverture et ladite largeur d'ouverture augmente progressivement en allant vers la charnière (5).
