Definitions

  • This invention relates to closure arrangements and, more particularly, to closure arrangements incorporating locking caps for pressurised containers.
  • the invention is applicable to containers, particularly bottles, intended to contain carbonated drinks.
  • An object of the invention is to provide a closure arrangement which eliminates the possibility of the cap flying-off the bottle.
  • the invention provides a removable closure cap for a necked container of the kind comprising a cup-shaped cap member and a gasket adapted to seal between the neck opening and the end wall of said cap member, and in which the skirt wall of the cap member has an internal thread or thread parts for co-operating with a mating external thread or thread parts on the container neck, characterised in that said end wall defines a first opening, in that the gasket is adapted when the closure cap is fitted to a container filled with fluid under pressure to be urged into a normally closed condition to seal said first opening, in that the gasket defines a second opening which communicates with said first opening to release fluid pressure only when said gasket is moved from its closed condition, and in that release means are provided externally of said closure cap, for applying pressure to said gasket for moving the latter away from its closed position to reduce the pressure in said container, whereby the closure cap can be safely removed from the container.
  • a lip encircles said first opening and projects inwardly from the end wall of said cap member to facilitate sealing engagement by said gasket.
  • closure member may be fitted to the cap member in a manner such that it is normally pre-biased into its closed condition.
  • said opening is defined in the end wall of the cap member and the closure member comprises a diaphragm of resilient material which is elastically deformed to seal across the opening of the cap member.
  • the vent means comprises one or more apertures in the wall of the closure member, providing a leakage path between the container and the opening only when the closure member is moved out of sealing engagement with said opening.
  • the cap member may conveniently be provided with protective cover which can be fitted over the cap opening.
  • an area i the cap wall is defined by a shaped opening, th arrangement being such that sealing pressure is release 0 via the shaped opening by applying pressure to said area.
  • Figure 1 is a perspective view of the firs embodiment
  • Figure 2 is a side view thereof
  • Figure 3 is a half-sectional view thereof
  • Figure 4 is a perspective view of the secon
  • Figure 5 is a half-sectional view of Figure 4,
  • Figures 6 and 7 are half-sectional views of modifie forms of the second embodiment.
  • the screw-cap 1 is of circular form an comprises an end wall 2 and a skirt wall 3.
  • the inne face of the skirt wall is formed with a screw-thread intended to fit onto a mating thread (not shown) around the neck of the bottle.
  • the inner face of the end wall 2 supports a closure member 5, in the form of a circular plastics disc, against which the free edge of the bottle is sealed in use when the mating threads are tightened.
  • the closure member 5 is made resilient and is oversized with respect to the inner diameter of the skirt so that when fitted within the skirt wall 3, as shown in Figure 3, its outer perimeter is gripped by internal ribs 6 provided on the inner face of the skirt wall and is thereby deformed to be convex.
  • the member 5 thereby acts as a diaphragm with its central portion elastically biased into sealing engagement with an inwardly projecting circular lip 8 defining the mouth of a central opening 9 through the end wall 2.
  • a boss 10 is provided on the central portion of the closure member 5 and projects into the opening 9.
  • closure member 5 is provided with at least an aperture or series of apertures 11 which, when the cap is fitted onto a bottle, provides a vent for the pressure of the liquid contained therein to a space 12 defined in the end wall between the lip 8 and the skirt wall 3.
  • a protective cover 13 is preferably hinged to the end wall of the cap to close over the boss 10 and hence prevent unintentional operation.
  • the screw cap when fitted to a bottle containing a carbonated drink, the carbonated pressure will act on the closure member 5 to increase its sealing pressure.
  • the user To open the bottle safely, the user must first press the boss 10 to release the seal between the lip 8 and the member 5, thereby releasing the pressure within the bottl-e via the vent aperture 11, space 12 and cap opening 9. This release of pressure reduces the frictional tension between the mating threads whereby the cap can be readily opened with a minimum gripping pressure and without any possibility of the cap flying-off the bottle neck.
  • the opening is in the form of a near circular slit 9A in the end wall 2 of the cap member 1, the portion 14 of the end wall between the ends of the slit being left to act as a hinge.
  • the plastics closure member 5 is dimensioned to fit snugly within the inner diameter of the skirt wall 3 and be retained in position against the inner face of the end wall behind a circular rib 6.
  • the closure member 5 is not pre-biased into contact with the end wall; instead it relies upon the carbonation pressure, exerted upon it when fitted, to effect sealing of the opening 9A.
  • the bottle can be depressurised via the apertures 11 by applying pressure to the area 15 bounded by the slit opening 9A.
  • the closure member 5 could be pre-biased, e.g. by oversizing said closure member as for the first embodiment described above.
  • the inner face of the end wall 2 of the screw-cap 5 may be curved as shown, and the closure member 5 dimensioned to provide a corresponding curve when seated behind the rib 6.
  • the outer face of the end wall 2 instead of being provided with a protective cap, may be formed as a concave surface 16 to reduce the possibility of accidental pressure being applied to the area 15.
  • the end wall 2 of the cap can be formed with a tear-off tab defined by lines of weakness so that the tab must first be removed to produce the opening.

Abstract

Système de fermeture destiné notamment aux récipients tels que les bouteilles de conditionnement de boissons gazeuses. Il comporte un bouchon (1) possédant un dispositif de fixation tel qu'un filetage servant à fixer de manière hermétique le bouchon sur le récipient. Le bouchon possède une ouverture (9) normalement fermée hermétiquement par un obturateur (5) situé à l'intérieur du bouchon et sollicité de telle sorte qu'il demeure dans sa position d'obturation normale lorsque le bouchon est mis en place sur le récipient. Un dispositif d'évacuation (11) est associé au bouchon et destiné à ne décomprimer le fluide que lorsqu'on déplace le bouchon dans le sens contraire au sens dans lequel s'exerce la pression de sollicitation, en vue d'ouvrir l'ouverture. De préférence, le bouchon (5) est sollicité de telle sorte qu'il demeure dans sa position de fermeture, et il peut comporter une membrane en matière élastique. L'ouverture peut se présenter sous la forme d'une fente sensiblement circulaire (9A) afin de former une zone (15) sur laquelle on exerce une pression afin de décomprimer le fluide. Ce système de fermeture empêche le bouchon de se détacher violemment du récipient car la pression du fluide est réduite avant l'ouverture de celui-ci.
