Definitions

  • the invention relates to a tamper-evident protective cap for a valve in a keg barrel.
  • Keg barrels are metal barrels for holding beer and the like.
  • the kegs are provided at the base with a valve which can be connected to a pipe for dispensing the beer which is usually forced out of the keg and through the pipe by internal carbon dioxide pressure.
  • the valve projects a small distance beyond the base of the barrel and is surrounded and protected by a circular flange provided on the keg.
  • a cap which covers the valve and is held in place by retention means which lock under the circular flange.
  • the above caps be tamper-evident, ie that it should be possible to tell easily when a cap has been removed and replaced.
  • US 4607759 discloses a sealing cap for a keg barrel which has a circular flange to protect its valve.
  • the cap is made of plastics material and includes a cover plate, a cylindrical guideway projecting from the cover plate and a plurality of locking elements on the guideway biased inwardly to engage under the circular flange.
  • the locking elements are arranged such that the sealing cap cannot be removed from the barrel without at least some of the locking elements being damaged or torn from the rest of the cap.
  • the locking elements may break off individually from the cap or a part of the cap including several locking elements may break off along rupture lines. The state of the locking elements therefore shows whether or not the barrel has been tampered with.
  • the invention provides a cap made from plastics material, for protecting a valve in a keg barrel having a circular flange associated with the valve, the cap including:
  • the basic outline shape of the skirt is cylindrical because it mounts the retention elements which engage under the cicular flange.
  • the skirt need not be a solid cylinder and may contain windows.
  • the only limitation is that the skirt should be sufficiently rigid that it is not possible to prize up and disengage the retention elements to remove the cap from the circular flange without causing discernible damage to the cap.
  • the skirt is divided into a first part extending from a portion of the cover plate on one side of a hinge and a second part extending from another portion of the cover plate on the other side of the hinge; and the two parts of the skirt are joined only by a weak connection.
  • a weak connection it is meant that when a force is applied to the cap to bend the cover plate at the hinge, the weak connection snaps, allowing the two parts of the skirt to pivot away from one another.
  • the connection should not be so weak that it can break accidentally, but an average person should be able to snap it easily.
  • the weak connection may consist of elements of plastics material which complete a distal circumference of the skirt remote from the cover plate. When a force is applied to the cap to cause the cover plate to bend at a hinge, these elements are placed in tension and snap, allowing the two parts of the skirt to pivot away from one another.
  • the discernible damage to the cap is preferably the breaking of the weak connection, and preferably the cap cannot be removed from the barrel without breaking this weak connection.
  • a tab may be attached to the skirt so that lifting of the tab causes bending of the cover plate at the hinge or hinges, when the cap is in place on a keg.
  • a prior art tamper-evident cap includes a cover plate 1 and a cylindrical skirt 2 extending from the circumference of the cover plate.
  • Retaining elements 3 are attached to the skirt at a lower region spaced from the cover plate.
  • the retaining elements can bend slightly to allow them to pass over a circular flange 4 associated with a valve on the keg.
  • the retaining elements 3 grip under the circular flange 4 and retain the cap over the valve. The cap cannot be removed without damaging the retaining elements 3.
  • a tab 5 is pulled upwards away from the keg. This may cause the retaining elements to break off individually at fracture zones 6.
  • fracture zones may be provided in the region 7 where the skirt 2 meets the cover plate 1 to allow a portion of the cap containing several retaining elements to split from the rest of the cap. However the fracture zones are arranged, it is clear that some breakage of the cap will occur when removing it from the circular disc 4 to free the valve.
  • a moulded plastics cap according to the invention includes a cover plate 1, a substantially cylindrical skirt 2 and retaining elements 3 which retain the cap on a circular flange 4 in a similar manner to the prior art. Ribs 15 help guide and locate the cap on the circular flange.
  • the cover plate 1 includes a hinge 8 located approximately on a diameter of the cover plate.
  • the hinge 8 divides the cover plate 1 into first 9 and second 10 portions.
  • a first part 11 of the skirt 2 extends from the first portion 9 of the cover plate 1 and a second part 12 of the skirt 2 extends from the second portion 10 of the cover plate.
  • a cap according to the invention does not break up when pulled off a keg, and does not cause mess or waste. It is easy for the user to re-fit the cap when the keg is empty and the entire cap can be recycled by the brewery.
  • the cap of the invention is injection moulded, with a styrene based plastic being a preferred material.
  • the hinge simply consists of a line on the cover plate along which the plastic has a reduced thickness.
  • the hinge 8 may be offset slightly so that it does not pass right through the centre of the cover plate 1.
