Definitions

  • This invention relates to an easy open container according to the preamble of claim 1 and to a method of sealing the easy open container of claim 1.
  • the container has a body with seamed or integral base, a metal ring which is seamed to the open end of the can body, and a press-on lid which can be opened by inserting a lever into a channel at the edge of the ring.
  • the press-on lid has a U-shaped channel for inserting the lever, and a flange, which extends radially outwardly from the channel.
  • a plastics ring is clipped over the raw edge of the lid and extends around an outwardly rolled circumferential edge flange of the can body when the lid is pressed down onto the can body.
  • an easy open container in accordance with the preamble of claim 1 is known from document CH 624 356 .
  • a method of sealing a container by forming complementary beads is furthermore known from document FR2387855 A1 .
  • an easy open container according to claim 1.
  • the plastics ring of the lid structure provides openability when the iid structure is fixed to a container, without the need for any tool. After tearing the lower ring profile, the lid structure is removable from the container, such that the container appears to the user to have only two parts.
  • the centre panel of the lid may be joined to the outer wall by a generally U-shaped channel. This prevents excessive intrusion of the lid structure into the headspace of the can body.
  • sealing compound may be provided around the lid annulus and adjacent the outer wall.
  • the line of weakening is tearable and defines a tamper evident strip or band.
  • the can body has an outward curl at the edge of the opening so that the ring engages this can body curl.
  • a method of sealing an easy open container according to claim 5 is provided.
  • the method may be used with a lid structure having a U-shaped channel so that an expandable tool may be inserted into the channel for applying radial force to the channel outer wall to form the beads.
  • Figure 1 is a perspective view from above of the plastics ring
  • Figure 2 is a perspective view from below of the plastics ring
  • Figure 3 is a side section of the plastics ring, through the cut in area 'C';
  • Figure 4 is a side section of the plastics ring, through the cut in area 'D';
  • Figures 5 is a schematic side view showing the plastics ring and metal lid assembly
  • Figures 6 to 9 are schematic side views showing the application of the lid structure onto a can body.
  • Figure 10 is a schematic side view of the closed container.
  • the plastics ring of figure 1 has an annular shoulder 2 and a skirt having an inner wall 3 and an outer wall 4.
  • a tab feature 5 on the outer wall is provided for gripping by a user when opening a container as is described in more detail below.
  • Lug 6 of the example is a fully circumferential lug for engaging a metal lid to form a lid structure and a lower profile 7 on the inner wall for engaging the container body.
  • Figure 2 is an underneath isometric view of the ring of figure 1 , showing cut regions 'A', 'B', 'C' and 'D'. In the side sections of figure 3 and/or 4, the annular shoulder 2, lug 6 and tab 5 can be clearly identified.
  • Lower profile 7 includes teeth 8 in uncut regions which assist in gripping the container body.
  • the cut in the 'C' area is indicated by reference 9 in figure 3 that of the 'D' area by reference 10 which extends from the tab 5 of figure 4 .
  • FIG. 5 shows the lid structure which combines the plastics ring 1 with a metal lid 20.
  • the lid 20 comprises a centre panel 21, inner and outer walls defining a channel 22, the outer wall 23 leading into an outwardly extending annulus 24, and terminating in a raw edge.
  • the plastics ring is clipped over the annulus 24 so the shoulder 2 covers annulus 24 and lug 6 covers the edge of the lid at 25.
  • a downwardly extending portion 41 of the tool 40 has a radially outwardly extending bead 42 which is moved into contact with the outer wall 23 by applying a radial expansion force. Downward pressure is maintained whilst the expansion force is applied to ensure correct positioning of the bead 42 against the outer wall 23.
  • the compression of the compound is maintained during the expansion. This compression is also maintained after the blocking of the lid in the body and partly by the plastic ring.
  • the combined forces are applied until complementary beads are formed in the lid wall 23 and can body wall 32, beneath the curl 31.
  • the tool 40 is then retracted radially, with downward pressure maintained ( figure 9 ) and tool 40 removed to leave the finished structure of figure 10 .
