Definitions

  • This invention relates to an improved security stopper, of the type comprising an integral moulded material, preferably plastics, body used as a screw cap.
  • Security stoppers comprise a portion which may be removed from the rest of the stopper, the parts becoming separated when the stopper is unscrewed.
  • This type of stopper comprises essentially an upper portion forming the main body thereof, and which in prac­tice is the genuine stopper, formed by a hollow cylinder of revolution open at the lower end and provided with an outwardly projecting screw thread on the inner sidewall thereof.
  • a circular skirt is attached to the stopper body. The connection between both components is limited to a number of points or threads which break when the stopper is unscrewed.
  • said skirt includes a number of projections or protuberances located on the inner portion thereof which, when the stopper is screwed on, should be held under the arcuate retaining ridge with which bottlenecks are provided In this way, when the stopper is unscrewed upwardly, since the skirt cannot follow because of the engagement of the projections or protuberances thereof with the bottleneck ridge, is when the threads joining the seal components break
  • the stopper of the present invention has been devised and provides as main advantage the fact that the projections on the inside of the skirt attached to the stopper are formed by protuberances which may take on different forms, but which are essentially characterized in that they are hollowed out in the outside/inside direction that is, on a skirt, for example, 1 mm thick, the inward projection of said protuberances has a wall thickness of 0.3 mm to 0.5 mm, for example, whereby said arcuate or semispherical protuberances, among other ad­vantages, have the power of yielding easily when the stopper is being screwed on and easily pass over the thread area and the ridge area in the opposite direction to the bottleneck, whereas they oppose sufficient resist­ance when the stopper is unscrewed to cause breakage of the points or threads joining the skirt to the stopper body.
  • a security stopper of the type comprising a main body, generally referenced with 1 and a break-away skirt 2, both obtained in the same moulding stage, said components being associated by points or filaments 3, of the same weakened material, said skirt including means devised to be situated below the ridge on the bottleneck.
  • the stopper is characterized in that the said means in­cluded in the skirt 2 are formed by respective holes or hollowed out or portions 4, formed in the outer surface of the skirt, which holes or hollowed out portions gen­erate respective protuberances 5, which extend radially from the inner surface of the skirt, formed by fine thin walls to facilitate yielding, so as to be able to move resiliently without difficulty over the whole of the bottleneck thread and the retaining ridge thereof.
  • the lower edge of the sidewall of the stopper body is provided with castellations 6 which form a stop member with the skirt 2 to prevent deformation by compression of the threads 3 when the stopper is fitted in place.
