Definitions

  • the present invention relates to a screw cap for use in combination with a container, which is provided with a neck having a retention device, said screw cap comprising an outer cap and an inner cap, which are mutually displaceable both in radial and in axial direction relative to a longitudinal axis of the container neck, said screw cap compris ⁇ ing tracks and also along an inner side of the inner cap comprising a retention device designed to engage with the retention device on the container neck, and said screw cap comprising a skirt with projections arranged at a lower part of the skirt, said tracks being arranged along the skirt of the inner cap at relative angular positions, and said projections being arranged at relative angular positions equal to the relative angular positions of the tracks.
  • US 3,893,582 describes a child resistant screw cap for a container having a threaded neck.
  • the screw cap comprises an inner cap and an outer cap.
  • the inner cap comprises a skirt supplied with flaps.
  • the flaps are flexible so that they are able to form an en ⁇ largement of the circumference of the skirt.
  • the outer cap comprises a skirt that may be displaced upwardly or downwardly in relation to the inner cap.
  • An engagement device between the outer cap and the inner cap is designed to retain the outer cap in a downwardly oriented position relative to the inner cap in a first position. In this posi ⁇ tion the flaps in the inner cap are retained around the thread on the container.
  • a recess in the flaps seizes a rim on the container neck so that the cap cannot be removed from the container.
  • the outer cap In a second position the outer cap has been displaced upward relative to the inner cap. The engagement of the recess with the rim is thus brought to an end, and the inner cap may be unscrewed
  • This screw cap possesses various disadvantages. Upward displacement of the outer cap relative to the inner cap in order to be able to unscrew the screw cap from the container does not require any particular logical sense but merely sufficient strength to perform this displacement. Thus, it cannot be excluded with certainty that a child having sufficient strength will be able to remove the screw cap from the container. Besides, the retention function of the outer cap in relation to the inner cap is condi- tioned by engagement between a tongue and a corresponding edge. After use several times there is a risk that the tongue, respectively the edge, will be worn, whereby the retention function ceases or at least is reduced. Furthermore, the screw cap may be so difficult to remove from the container that even not elderly or weak persons are able to remove the screw cap.
  • GB 2 252 961 discloses a child resistant screw cap for a container having a threaded neck.
  • This screw cap also comprises an inner cap and an outer cap.
  • the outer cap comprises a skirt provided with flaps.

  • the projections and the tracks form an engagement device designed to retain the outer cap in a downwardly oriented posi ⁇ tion relative to the inner cap in a first position.
  • This screw cap possesses an important disadvantage.
  • the outer cap and the inner cap have to be brought into mutual alignment before the projections on the skirt of the outer cap may be displaced upward into the tracks on the inner cap.

  • a screw cap with several combinations but wherein only one combination makes it possible to remove the cap from the container means an increase in the requirements on logical thinking by the person wanting to remove the screw cap from the container.

Abstract

L'invention porte sur un bouchon vissable (1) non manoeuvrable par les enfants et qui dans son exécution préférée est bloqué pour le transport tout en présentant une non-manoeuvrabilité par les enfants renforcée. Ledit bouchon comporte une capsule extérieure (6) et une capsule intérieure (7) mobiles l'une par rapport à l'autre le long et autour de l'axe longitudinal (A). La capsule extérieure (6) comporte des protubérances (18, 19, 20, 21) disposées à la partie inférieure de la jupe (9) de cette même capsule extérieure (6). La capsule intérieure (7) comporte des rainures (30, 31, 32) et un évidement disposés le long de la jupe (24) de cette même capsule intérieure (7). Il n'est possible de dévisser le bouchon (1) du récipient qu'en engageant les protubérances dans les rainures. Le bouchon (1) se caractérise en ce qu'il nécessite une réflexion logique pour être dévissé. Il ne demande pour être ouvert que l'effort nécessaire pour dévisser un bouchon de type ordinaire. Il peut de ce fait être manipulé par des personnes âgées ou faibles.
