Definitions

  • the invention relates to a beer keg cap.
  • a known beer keg cap is described in EP 0652162.
  • the document discloses a tamper evident cap for a keg spear comprising a flat, circular top and a depending skirt.
  • the skirt includes a large number of apertures and from the base of each aperture a tooth extends inwardly and upwardly. Each tooth is substantially rectangular and elongate inwardly.
  • the teeth are arranged to snap onto the neck of the keg spear and engage under the annular projection of the neck to retain the cap.
  • a tamper evident ring is provided connected to the skirt by frangible tags.
  • a beer keg cap comprising a continuous cup shaped member to receive the neck of the beer keg, and means for engaging the beer keg to retain the cap.
  • cup shaped member is continuous, moisture and dirt cannot readily enter the cap to contaminate the keg unlike the known cap described above which has a large number of apertures in the skirt.
  • the cup shaped member may comprise a top and a depending skirt and the skirt may include at least one line of weakness extending upwardly from its lower edge to provide tamper evidence by breaking.
  • a beer keg cap comprising a cup shaped member comprising a top for the keg neck and a skirt depending from the top to lie around the neck in use, the skirt including at least one line of weakness extending upwardly from its lower edge to provide tamper evidence by breaking.
  • the known cap includes a ring which is broken away from the main part of the cap on tampering, this is entirely different from the tamper evident arrangement of the present invention.
  • the separation of the ring is inconvenient as the ring then remains on the keg while in the present invention tampering does not result in separation of the cap into two parts.
  • the use of lines of weakness in the skirt is also significantly easier to manufacture.
  • the or at least one line of weakness may extend over the whole of the height of the skirt and preferably the or at least one line of weakness extends over the whole of the height of the skirt and continues over at least part of the top, preferably at least half of the top. Breaking of the cap along the or each line of weakness will assist in removal of the cap.
  • the section between two lines of weakness includes means to enable the section to be pulled to thereby break the said two lines of weakness.
  • the means may comprise a finger loop.
  • the cap may include a plurality of inwardly directed tabs to engage under the neck of a beer keg, each tab being elongate in a circumferential direction.
  • a beer keg cap including a plurality of inwardly directed tabs to engage under the neck of a beer keg, each tab being elongate in the circumferential direction.
  • Circumferentially elongate tabs of this type are strongly resilient and also act to spread stresses on the cap.
  • the tabs may be provided in a ring around the circumference and the edges of neighbouring tabs in the ring are preferably closely adjacent.
  • each tab may be convex and preferably each tab is substantially symmetrical about a chord of the cap.
  • the cap 10 of the embodiment comprises a planar circular top 12 and a depending skirt 14.
  • the skirt 14 includes a slight flare to be frusto-conical in shape.
  • a circumferential ring of inwardly directed tabs 16 project from the inner surface of the skirt 14.
  • the tabs 16 are each elongate in the circumferential direction and are substantially symmetrical about a chord of the skirt 14 parallel to the top 12.
  • the tabs 16 extend from the skirt 14 at about one-third of the height of the skirt 14 from the lower edge 18 of the skirt 14.
  • a finger loop 28 is provided and each end of the loop 28 is connected to the lower edge 18 of the skirt 14 immediately adjacent a life of weakness 20 such that the loop 28 is connected to a section between two closely spaced lines of weakness 20.
  • the finger loop 28 is symmetrical and each arm 32 of the loop 28 extends radially outwardly initially and then circumferentially before curving upwards and then linking with the other arm to form a U-shape such that the loop 28 is substantially the same height as the skirt 14.
  • the cap may be injection moulded from polypropylene, high temperature polyethylene or polystyrene.
  • the cap 10 In use, the cap 10 is forced over the annular projection 32 on the neck 34 of a beer keg. In this action, the tabs 16 are bent upwardly and engage under the annular projection 32 to retain the cap 10 on the beer keg neck 34. The tabs 16 will be resiliently bent in this position. If someone should attempt to tamper with the beer keg, attempted removal of the cap will lead to splitting of the skirt 14 along one of the lines of weakness 20 which provides evidence of tampering. Dirt and moisture are prevented from entering the keg as the top 12 and skirt 14 of the cap 10 are continuous. When it is desired to open the keg, the cap 10 is removed by inserting a finger through the finger loop 28 and pulling upwardly. The cap 10 will break along the lines of weakness 20 adjacent the loop 28 and further pulling of the tab 28 will cause the top 12 of the cap 10 to be broken along the lines of weakness therein such that the cap 10 can be pulled off the beer keg neck 34.
  • two additional lines of weakness 20 are provided in the remaining two positions between adjacent tabs 16.
  • the part of the line of weakness 20 which extends circumferentially in the top 12 of the cap 10 does not meet up with another line of weakness but terminates after a distance of no less than one sixth of the circumference of the cap 10. In removal, the cap can be broken across the top 12 to at least half way across, the remainder of the cap 10 will flex sufficiently for the cap 10 to be removed.
