Definitions

  • the invention relates to so called "pilferproof" closures.
  • Such closures are well known and are used extensively on containers for ensuring that when a purchaser buys a particular liquid he can check that the container includes all the contents with which it was filled.
  • Such pilferproof closures have been used on oil cans and on plastics containers containing a wide range of liquids.
  • the closures usually comprise a cap and, integrally joined to the cap by a plurality of bridges, a ring of larger diameter which is arranged to engage complementary abutments on the container in use, to prevent unscrewing of the cap from the container without breaking of the bridges. Breaking of the bridges is arranged to require a predetermined torque so that accidental breaking is not normally possible. Thus, broken bridges on a closure on a container are an indication that the container has been tampered with.
  • Pilferproof closures are increasingly used on blow moulded plastics containers intended for containing a wide range of liquids including household and industrial detergents, oil and numerous other chemicals.
  • the larger diameter ring on such closures usually forms a ratchet engaging a number of abutments on the container adjacent its spout and the bridges, which usually extend radially of the cap, are snapped-off in a circumferential direction when the cap is unscrewed.
  • certain plastics materials notably polypropylene
  • the initial slight elongation of the bridges as the cap is rotated relative to the ring increases the strength of the bridges making it extremely difficult for a legitimate user of the liquid within the container to remove the cap initially.
  • the ring is normally provided radially externally of the cap, it may be possible for the ring to be positioned axially spaced from a closure formed as a screw-threaded plug.
  • a screw-on plastics closure for a container comprises a cap, and, integrally joined thereto adjacent an edge thereof by means of a plurality of bridges, a locking ring for securing to the container in use to prevent unscrewing of the cap from the container without breaking of the bridges, characterized in that the bridges extend from the adjacent part of the cap to the ring at an angle inclined in the direction of unscrewing of the cap.
  • bridges with a depth which is greater than their width in order to increase the; security of the bridges when they are subjected to loads in the axial direction of the cap, for example during transport when they may be stacked one on top of another.
  • the closure is formed of polypropylene and comprises a cap 1, of approximately 38mm diameter, having an internal raised screw-thread 2 formed on the annular sidewall 3. Joined to the cap 1 by eight bridges 11 which extend outwardly, and inclined to respective radii in the direction of unscrewing (A) of the cap 1, is a ring 4 which includes a number of inwardly projecting tangs 5 (in the present example 12 in number) extending inwardly inclined to respective radii of the ring in the direction of unscrewing of the closure.
  • the tangs 5 are moulded so as to have sufficient resilience to enable them to ride over ratchet-like projections 6 formed on the spout 7 of the container 8 during screwing-on of the closure, but, when an attempt is made to remove the cap the tangs are compressed substantially longitudinally by engagement against the projections 6 and prevent rotation of the ring in the unscrewing direction (A) (in this case anti-clockwise).
  • the spout 7 has an upstanding rim 9 on the exterior of which are formed a number of part helical screw-thread projections 10 for engagement with the screw-thread 2 on the cap 1.
  • the ratchet projections 6 are ten in number and are provided in two sets of five in diametrically opposite halves of the spout with a slight gap between them. This is done so as to reduce the torque which is necessary to screw on the cap, only some of the tangs 5 engaging completely respective projections 6 by virtue of the oval shape of the envelope of the projections 6.
  • the bridges 11 have, of course, to provide for sufficient flow of plastics material during moulding from the cap 1 to the ring 4 and as such have a cross-sectional area of 0.465mm 2 . In order to provide strength against forces acting on the closure in the axial direction the bridges 11 have a depth of 0.93mm which thus enables the required cross-section area to be provided by a width of 0.50mm.
  • the closure shown is moulded in polypropylene, but this is not essential and it is envisaged that the mould necessary to produce the above closure could be used to produce closures in various other plastics materials as well.
  • the bridges are inclined radially outwardly in the direction of unscrewing, it will be appreciated that if the ring were axially spaced from the cap the bridges would still be inclined, but only axially. Alternatively were the ring to lie radially inwardly of the cap, the bridges would extend inclined radially inwardly in the direction of unscrewing of the cap.
