Definitions

  • the invention relates to a cap for an airtight container such as a glass or plastic bottle or jar, which cap is suitable to be placed releasably in a closing position on a neck of the container, wherein the cap is provided with visual indicating means for indicating that the cap is no longer in the closing position.
  • Such caps cannot be manufactured in practice, or hardly so.
  • Such indicators must after all be stored after manufacture in a nitrogen-free or oxygen-free environment before being arranged on the bottle.
  • Another problem is the difficulty of finding an indicator which does not react to the presence of the gases or liquids normally present in the containers, such as carbon dioxide and water.
  • the present invention provides such a cap, wherein the indicating means are adapted to be brought into an active state when the cap is arranged on the neck of the container and to be brought into the indicating state when the cap is removed.
  • the indicating means are adapted to be brought into the active state when the cap is displaced relative to the neck of the container.
  • the indicating means therefore comprise a mechanical connection which is adapted to be broken when the cap is placed on the neck of the container.
  • the indicating means can for instance comprise an indicator which is enclosed in an envelope, wherein the envelope is broken during arranging of the cap on the bottle or jar. The envelope is then still held fixedly however due to the presence of the upper edge of the neck of the bottle, so that only when the cap is loosened is the envelope no longer held fast, and the environment in the form of nitrogen or oxygen is given the opportunity to reach the indicator.
  • the mechanical connection is formed by a limp element which is fixedly attached to the cap on two sides and which is provided with a weakened portion at the position where the limp element makes contact with a component of the container when the cap is arranged on the container, and that the limp element is held fast at the weakened portion by the clamping between the cap and the neck of the container.
  • FIGS. 1 A- 1 C show partly broken-away, perspective views of a first embodiment of the invention at different stages
  • FIGS. 2 A- 2 C show partly broken-away, perspective views of a second embodiment of the invention at different stages.
  • the invention is applicable in the first place to bottles with optionally carbonated soft drinks, beer and so on, but is also applicable to bottles with a different content, and to for instance glass jars which are closed by a lid.
  • FIG. 1 Drawn in FIG. 1 is a cap 1 which is manufactured for instance from plastic. Cap 1 is provided on the inner side of its skirt in the usual manner with a screw thread 2 . Cap 1 can hereby be screwed onto neck 6 of a bottle. It is however not per se necessary that use be made of a screw-cap.
  • the invention is also applicable to for instance caps arranged by means of a clamp connection or otherwise on the neck of a bottle; the invention is even applicable to crown caps, although here the use of the invention requires special provisions in respect of the visibility of the breaking of the seal.
  • a transparent window 3 is arranged in the top surface of the cap.
  • the transparent window 3 gives a visual indication of the state of an indicator 5 arranged in an envelope 4 under window 3 .
  • Envelope 4 is for instance manufactured from a plastic film, which plastic film can be perforated by the upper part of the neck of a bottle when cap 1 is screwed onto such a bottle neck.
  • the indicator is formed by a substance which changes colour upon entry of a gas or a liquid normally to be found in the bottle. Assuming that the content of the bottle is formed by a soft drink, it is conceivable that an indicator is chosen which changes colour upon entry of carbon dioxide or water vapour and so on.
  • the colour change of indicator 5 can then be observed through the window 3 .
  • FIG. 1B shows how envelope 4 of indicator 5 comes into contact with the upper edge 7 of the neck 6 of a bottle.
  • This upper edge 7 will herein cause damage to envelope 4 , whereby this latter becomes permeable for gas and liquid at the position of the point of contact between the top side of bottle neck 6 and envelope 4 .
  • cap 1 When cap 1 is subsequently unscrewed, the part of envelope 4 damaged by the upper edge of the neck 6 of the bottle will be released. Such a situation is drawn in FIG. 1C.
  • a strip 8 of a flexible plastic is arranged on the underside of the top surface of cap 1 .
  • cap 1 is manufactured integrally from transparent plastic. It is otherwise also possible in this embodiment to apply a transparent window 3 in an otherwise coloured cap, just as it is possible to apply a wholly transparent cap in the first embodiment.
  • Strip 8 is made of easily tearable material and preferably fixed against the body of cap 1 under a slight mechanical tension on either side at the position of the point of contact with the upper part of the neck of the bottle.
  • the indicating means can be integrated into the liner, but can also be arranged separately under the liner.
