  • a form that is favorable in terms of production technology is thus selected at the same time.
  • An expedient development is possible in that an annular cover is formed on the outside of the cylindrical wall, which radially merges into the closure jacket on the outside. Due to a preferred horizontal section in the longitudinal section, ie perpendicular to the longitudinal axis of the closure, the ring cover can contribute to a low overall height of the closure cap.
  • the ring cover can carry a centering bead in at least one partial circumferential area of the outlet cross section, which cooperates with a ring groove or a comparable recess of the cover in its closed position with respect to the longitudinal axis.
  • the centering bead has one or more recesses directed radially inwards, which cooperate in a form-fitting manner with locking cams of the closure cover as a rotation lock.
  • a possible favorable embodiment with regard to the pouring behavior is seen in the fact that the pouring mouth as an elastic spring lip extends in an open position of the closure lid in the longitudinal, ie axial, direction of the closure beyond a reference plane, which in the closed position of the closure cover with its head or.

The left half of the picture also shows that the resilient reset is also the pouring mouth 5 is due to a support of the drip edge 6 in the area of the ring groove 43 of the closure cover 2. Depending on the configuration, an elastic reshaping of the pouring mouth, which leads to a reduction in the axial overall height in the closed position, can alternatively or in combination also be brought about by an abutment on the underside of the top plate between the ring seal 8 and the ring groove 43.

Abstract

L'invention concerne un capuchon de fermeture, notamment pour bouteille pouvant être remplie d'huile de table, qui présente un couvercle de fermeture (2) sensiblement circulaire, une enveloppe de fermeture (3) essentiellement cylindrique, un bec verseur (4) qui s'évase, au moins dans une zone partielle périphérique de la section transversale du bec, avec un orifice d'écoulement (5), en direction d'une arête de dégouttage (6), ainsi que des segments de languette (11) formés de manière adjacente sur une surface de la paroi intérieure, dans le sens périphérique, qui s'étendent en dedans dans le sens radial, de manière à maintenir dégagée une section transversale de passage centrale. Le capuchon de fermeture (1) se présente de manière monobloc. L'invention vise à perfectionner un capuchon de fermeture de ce type, pour le rendre avantageux en termes de manipulation et d'utilisation. A cet effet, il est prévu que l'enveloppe de fermeture (3) présente un filet intérieur pouvant être vissé sur le filet extérieur de l'orifice d'écoulement de bouteille.
