Definitions

  • the present invention relates to a cap for a container and is concerned with providing an improved seal between the cap and a container, especially for containing hygroscopic materials.
  • One particular use is for a container of tea, or coffee to permit resealing of the container, with exclusion of water vapour.
  • the invention is applicable to the type of cap in which there is means for effecting rotary disengagement with the container, usually by means of screw threads, but also, for example, by a bayonet fitting.
  • GB-2123392 One example of a prior art cap is disclosed in GB-2123392.
  • This cap has an annular projection of triangular cross-section and, initially a frangible sealing membrane is weakly adhered in the top of the cap across the projection and other flat-topped projections.
  • the opposite side of the membrane carries an adhesive which strongly adheres to the rim of a glass jar when the cap is secured on the jar. The cap can then be removed, the membrane broken and the jar resealed by engagement of the annular projection with the container rim.
  • a cap for a coffee jar for example, to have a separate, resilient wad adhered in the cap.
  • the frangible membrane is initially carried by the wad and adheres to the jar, so that, on opening of the jar, the wad separates from the membrane.
  • This arrangement still does not, however, provide a good seal, once the membrane has been broken, due to undulations in the rim of the jar. Furthermore, this is an expensive addition to a coffee cap.
  • GB-A-2117360 discloses a cap which has an improved sealing arrangement for taking account of thickness tolerances in a glass jar.
  • This document provides two radially spaced annular seals, dependent from the top of the cap.
  • One of these seals is resiliently flexible and is curved, so that a convex face of the seal engages with the jar rim.
  • the provision of two seals improves the probability of good overall sealing.
  • the design however is not suitable for supporting a frangible membrane and sealing is still unreliable, especially with glass containers.
  • EP-A-0568288 discloses an arrangement in which a single annular projection is provided to seal with the jar rim.
  • a stop ring is provided to limit the flexing movement of the annular projection. This permits the projection to be clamped, in use, between the stop and the top of the rim of a jar. This constructions is also unsuitable for mounting of a sealing membrane in the cap.
  • the present invention provides a cap which enables use of a sealing membrane having no adhesive to hold the membrane in the cap. This reduces costs and permits easier handling. In addition a food seal is provided with a container, despite frequent removal of the cap.
  • the present invention provides a cap for a container
  • the cap shown is a one-piece injection moulding of plastics material and has a top 11 and a skirt 12.
  • the skirt has an internal thread, or part threads, 13 for screw-engagement with threads 14 on a container, such as a glass jar 16.
  • the skirt also has an annular, radial inward support flange 17 between the top 11 and the threads 13.
  • the sealing member projects from a location adjacent to the skirt 12 inwardly away from the skirt, but could be radially spaced from the skirt and project towards the skirt.
  • the sealing member is an annular projection, which is elongate in cross-section and curves, so as to present a convex surface 21 to the top of the rim 22 of the jar 16, in use.
  • the curved surface 21 flattens at the free end part of the sealing member and lies generally in a radial plane relative to the skirt 12.
  • a frangible sealing membrane 25 is gripped between the support flange 17 and the free end part of the sealing member 20.
  • the membrane 25 has an adhesive surface opposite to the top 11 of the cap, so that, when the cap is screwed down onto a jar, the membrane adheres to the rim 22 of the jar and is resiliently urged against the rim by the sealing member 20.
  • the support flange 17, is released from the membrane and the sealing member 20 will re-engage with the rim of the jar on re- closure.
  • annular projection 30 of triangular cross-section, integrally formed with the top 11 of the cap.
  • the root of the projection 30 is radially spaced from the root of the sealing member 20, but the inner edge of the projection is located in axial alignment with a portion of the sealing member.
  • the arrangement is such that, when the cap is screwed down on the jar, the sealing member is clamped between the projection 30 and the rim of the jar. This provides a highly effective seal, which does not rely on maintenance of resilience in the sealing member.
  • a sealed chamber 31 is defined between the top 11 of the cap, the projection 30 and the sealing member 20, in the jar-closing position of the cap. This sealed chamber 31 provides resilience, urging the sealing member 20 into sealing engagement with the cap.

Abstract

Le couvercle d'obturation selon l'invention, qui est particulièrement utile pour fermer hermétiquement un bocal à café, comprend une membrane d'étanchéité (25) dont une face porte un adhésif lui permettant d'adhérer à toute l'embouchure d'un bocal lorsque ledit couvercle est vissé sur celui-ci. La membrane (25) est maintenue entre un anneau circulaire (17) situé sur la jupe du couvercle (12) et une partie d'extrémité (23) d'un élément d'étanchéité annulaire (20), cette partie d'extrémité (23) se trouvant sur un plan radial à la jupe. L'élément d'étanchéité annulaire (20) entre en contact élastique avec le rebord du bocal afin de refermer celui-ci hermétiquement après que la membrane a été rompue. Il n'est plus, de la sorte, nécessaire d'utiliser un adhésif léger pour faire adhérer la membrane au couvercle.
