Definitions

  • This invention relates to the securement of lids to containers, particularly containers such as paint cans.
  • GB-A-2096107 describes a clip for securing a lever lid to a lever ring of a container, where the clip comprises a moulded or extruded element or elements of plastics material which are applied to the container in a generally downwardly vertical direction such that the inherent resilience permits arm members of the clip to engage substantially simultaneously with associated surfaces of the lever ring and/or the lever lid.
  • the clip although firmly securing the lid to the ring, can easily be detached therefrom without the need for special tools.
  • EP-A-0334514 describes a lid-retaining collar which comprises a generally annular ring which has a radial slit therein so that the collar can more easily be parted from the can.
  • the collar has a peripheral skirt portion with a snap-fit bead which engages below the double seam between the lever ring and the can body.
  • lid-retaining devices In these and other lid-retaining devices the major problem is maintaining a complete seal against leakage of the contents if the can is dropped or otherwise subjected to impact or pressure. Particularly for cans which are used to contain flammable liquids there are specific standards which must be met. With overclo- sures of the types referred to above, leakage of the contents can still occur if for example the can is dropped in a particular attitude.
  • a container having a cylindrical side wall, a lever ring secured to the upper margin of the side wall, a lid fitted into the lever ring, a circumferential recess between the lever ring and the lid, a circumferential groove in the lid adjacent to the radially outer edge thereof, and an overclosure clip fitted to the lever ring and lid and extending around substantially the whole circumference of the container, wherein the clip has three depending portions engageable with the lever ring and/or lid, characterised in that the radially outermost portion of the clip engages below a lip on the lever ring and the two inner portions are each a tight resilient fit in said circumferential recess and said circumferential groove respectively.
  • the clip preferably includes a circumferential cushioning ring outwardly of the lever ring.
  • the clip is provided with a plurality of slots equispaced circumferentially around the clip from the radially inner margin of the clip outwards to create a plurality of radially inwardly projecting tongues.
  • the outer wall of the container lid is recessed and carries sealing means engageable between the lid wall and a facing surface of the lever ring.
  • an overclosure clip for a container comprising a strip having three depending portions engageable with a lever ring and/or lid of the container, characterised in that the clip includes a cushioning ring which in use lies radially outwardly of the outermost of the three depending portions.
  • a container having a cylindrical side wall, a lever ring secured to the upper margin of the side wall, a lid fitted into the lever ring, a circumferential recess between the lever ring and the lid, a circumferential groove in the lid adjacent to the radially outer edge thereof, and an overclosure clip fitted to the lever ring and lid and extending around substantially the whole circumference of the container, wherein the clip has three depending portions engageable with the lever ring and/or lid, characterised in that the outer wait of the container lid is recessed and carries sealing means engageable between the lid wall and a facing surface of the lever ring.
  • a cylindrical can wall 10 having a lever ring 12 secured thereto by a seaming operation which defines the periphery of the can.
  • the lever ring 12 has a lip 14 outwardly of the cylindrical can wall.
  • the lever ring 12 has an inturned portion radially inwardly of the cylindrical wall 10 and which defines a circumferential recess 16.
  • a can lid, indicated generally at 18, is a socket fit within the lever ring 12 and has a circumferential lip 19 which overlies the inner portion of the lever ring 12 and thus faces the recess 16.
  • the lid 18 includes a circumferential pocket 20.
  • an overclosure or clip is designed and shaped to fit over and into the can rim as shown in Fig. 1.
  • the clip 22 comprises a vertically extending skirt 24 which has an inwardly and upwardly directed tongue 26 which is adapted to engage below the lip 14 on the lever ring 12.
  • the clip 22 has an arm portion extending inwardly from the skirt 24 and adapted to make contact both with the recess 16 and with the pocket 20.
  • a protuberance 28 extending downwardly from the clip is designed to seat resiliently within the circumferential recess 16.
  • the radially most inward portion 30 of the clip is designed to seat resiliently within the circumferential pocket 20.
  • the portion 30 has two ribs 31 and 32 which engage the circumferentially innerface 33 of the pocket 20 and a surface 34 which engages the circumferentially outer face 35 of the pocket 20.
  • the portion 30 of the clip 22 is a tight, resilient fit within the circumferential pocket 20.
  • the clip 22 as shown in Fig. 2 includes an outer circumferential cushioning ring 36 to aid in absorbing impacts if the can is dropped on its rim.
  • the cushioning ring 36 is preferably tubular and may be made of the same material or a different material from that of the rest of the clip 22.
  • the cushioning ring 36 is made of a flexible PVC material, whereas the remainder of the clip is made of a high impact PVC material.
  • the clip 22 is desirably extruded and the cushioning ring 36 and the remainder of the clip can be co-extruded, with the cushioning ring keyed to t he basic part of t he clip in the extrusion process.
  • the clip 22 is shaped so that the clip is of substantially constant thickness throughout, i.e. the thickness of the skirt 24 and of the radially inwardly projecting arm and of the cushioning ring 36 are all of substantially the same dimension. This assists the extrusion of the clip so that one does not get areas or zones which are of different temperature to others.
  • the radially inwardly projecting arm portion of the clip is provided with a plurality of slots spaced circumferentially around the arcuate clip at equal intervals. These may be saw cuts through the thickness of the arm in order to create a plurality of radially inwardly projecting tongues.
  • These slots in the clip preferably extend from the ribs 31 and 32 to approximately the position indicated by the arrowAin Fig. 2. This gives the individual tongues a degree of resilience which enables them more easily to locate within the recesses 16 and 20. It also assists in the fitting of the clip by enabling it to be pushed on to the can, instead of having to be hammered on.
  • the can lid 18, as shown in Fig. 3, is provided with auxiliary sealing means.
  • the outer wall 38 of the can lid 18 is provided with a circumferential groove 40 which serves as a locator for an O-ring seal 42.
  • the O-ring seal 42 has a diameter of approximately 1.58 mm (1/16th inch) and the distance x by which the O-ring seal projects beyond the surface of the lid wall 38 is between 0.125 mm (0.005 inch) and 0.25 mm (0.010 inch).
  • these dimensions are given by way of example only.
  • the use of this O-ring seal 42 in combination with the clip 22 provides a double mechanism by means of which the can is securely sealed against leakage.
