  • the seaming of the top end member to the peripheral wall defines the connecting rim.
  • a protective ring for engaging around the periphery of a top end member of a container, the protective ring having a substantially circular channel defined between two spaced depending walls, the exterior surface of the channel defining an annular rim with a smooth surface.
  • the annular rim is a drinking rim.

  • Figure 5 shows an enlarged view of part of the protective ring of Figure 4.
  • the invention is described hereinafter with reference to a self-heating beverage container having a particular design of heating mechanism. However, the invention is applicable not only to self-heating and self-cooling beverage containers but to containers generally, although it does find particular applicability to beverage containers.
  • the container has an external cavity in which heating or cooling means is received, the external cavity being closed by a closure.
  • the invention is not limited to such an arrangement and can be used with other constructions of self-heating or self- cooling mechanisms.
  • the container shown in Figure 1 may be a metal or plastics material beverage container 10 having a substantially cylindrical peripheral wall 12 which is closed at one end by a top end member 14. As described in WO 96/29255, a base end member 16 of the container is indented to define an elongate external cavity 20 which extends within the peripheral wall 12. It will be appreciated that the peripheral wall 12 and the top and base members 14 and 16 of the container together define an internal cavity 22 in which the beverage is received. It will be seen that the external cavity 20 extends within this internal cavity 22, but is separated therefrom by the wall of the base member 16.
  • the container 10 illustrated in Figure 1 is configured to have the same external dimensions and shape as a conventional beverage can. This means that the can can be filled and treated on existing filling lines.
  • the can 10 may be made of aluminium or steel, as is conventional, and have a ring-pull opening means 50 ( Figure 3) in the top end member 14 as is also usual.
  • the external cavity 20 of the can 10 is to be utilised to contain a heating mechanism.
  • the heating mechanism comprises a first reactant material, which, for example, may be quicklime (calcium oxide).
  • the cavity 20, incorporating the quicklime is closed by a closure 30.
  • this closure 30 may contain water.
  • the can When it is required to heat the contents of the can 10, the can is inverted and stood on its top member 14 so that the base of the closure 30 is accessible. A button on the bottom of the base is depressed whereby a water chamber 42 within the closure 30 is opened so that water from the closure 30 flows over the quicklime in the reactant cavity 20 to cause the exothermic reaction.
  • a protective ring is provided around the upper periphery of the can as indicated in Figure 2.
  • the protective ring 52 which is preferably of an insulating material, is arranged not only to insulate a consumer's lips from the heat, for example, from the can but also to provide a smooth drinking rim.
  • Figure 3 shows the top end member 14 of the can and shows opening means provided in the form of a ring-pull arrangement indicated generally at 50.
  • the connecting rim 54 which is conventionally formed on a beverage can, and an annular groove 56 which is generally provided around the periphery of the top end member 14 adjacent to the connecting rim 54.
  • a conventional metal beverage can may be made in two or three pieces.
  • the substantially circular top end member 14 will be seamed or otherwise joined to the peripheral wall 12 after filling of the can and the substantially circular connecting rim 54 results from that seaming operation as does the annular groove 56.
  • the protective ring 52 is engaged on the connecting rim 54 to enclose both the connecting rim 54 and the annular groove 56.
  • FIGs 4 and 5 An embodiment of a protective ring 52 of the invention is shown in Figures 4 and 5.
  • Figure 4 a section through the whole ring 52 is shown whereas Figure 5 shows an enlarged view of part of that section.
  • the protective ring 52 which is preferably made of a plastics material, is moulded to have a substantially circular channel 60 defined between two spaced depending walls 62 and 64.
  • the outer depending wall 62 is provided with a substantially circular projection 66 which engages, as indicated in Figure 2, in an annular exterior groove 70 in the peripheral wall of the can 10.
  • the inner depending wall 64 has an extension indicated at 68 which, as is apparent in Figure 2, encloses the annular groove 56.
  • the protective ring 52 is affixed to the beverage container 10 as required. For example, it may be arranged to be fixed by a consumer at the point of use, or it may be fitted at an appropriate point in the supply chain. Thus, the protective ring may be fitted as part of the operations on a filling line or it may be fitted by a wholesaler or retailer.
  • the nature of the material of the protective ring 52 and the means by which it is secured on to the can 10 may be chosen according to circumstances.
  • the protective rim may be made of a thermoplastics material which expands on heating and contracts back to its original shape on cooling.
  • the protective ring 52 can be shrunk fit on to the connecting rim 54 of the can and substantially permanently applied.
  • the ring 52 may be clipped onto, or adhered to, the beverage can 10.
  • the material of the protective ring 52 may be made to be resilient so that the ring can be clipped into position by way of the projection 66.
  • the exterior surface of the ring 52, and particularly of the channel 60 defines an annular surface which is arranged to be smooth and have a pleasant mouth feel and, for a beverage container, defines a drinking rim.
  • the extended portion 68 of the inner depending wall 64 of the ring 52 encloses the annular groove 56 and thereby protects a drinker from contaminants.
  • the protective ring 52 is preferably made from an insulating material, it is able to protect the lips of the consumer from the temperature of the can.
  • a protective ring of the present invention will have its main applicability as a drinking rim for a beverage container, it may be used on other containers, for example, to protect the connecting rim against damage.

Abstract

L'invention concerne une collerette annulaire (52) de protection coopérant avec un rebord (54) au niveau de la périphérie d'un élément d'extrémité (14) supérieur d'un récipient à boisson (10). Cette collerette annulaire (52) de protection comprend un canal sensiblement circulaire (60) défini entre deux parois dépendantes (62, 64) espacées. Elle est constitué d'un matériau isolant de sorte qu'une surface lisse permettant l'absorption de boisson ainsi définie protège les lèvres d'un consommateur contre la chaleur ou le froid du récipient. Ladite collerette annulaire (52) de protection peut protéger le rebord (54) contre une détérioration, et une extension (68) de celle-ci protège le consommateur contre l'ingestion de poussières ou de contaminants collectés dans une rainure annulaire (56) de l'élément d'extrémité supérieur.
