Definitions

  • This invention relates to hinged closures for bottles and the like hereinafter simply called containers.
  • the hinged closures to which the invention relates comprise a cap part, a tcar band, an anchor band and a hinge to connect the cap part to the anchor band.
  • These hinged closures have in the past few years achieved a very considerable success commercially and our hinged closures known under the Registered Trade Mark JAYCAP and manufactured under British Patent No. 812580 are to be found on many different containers including bottles of still soft drink such as orange squash.
  • a hinged closure for closing the mouth of a container comprises a cap part, an integral anchor band adapted to embrace the neck of the container or that part of the container wall adjacent the mouth of the container and means for separating the anchor band from the cap part circumferentially except over a narrow interconnecting zone which constitutes a hinge, wherein the means for separating the anchor band from-the cap part includes an arcuate partial tear band and at least one arcuate area of weakness.
  • the closure comprises a cap part 1, a tear band 2 And an anchor band 3.
  • the cap part 1 is centrally dished at 4 and has a depending plug 5 for insertion into the mouth of a container.
  • the plug 5 has an external annular bead 6 and two annular lamellas 7 which seat against the inside of the mouth of a container.
  • the cap part 1 also has further annular sealing beads 8 and 9 and the bottom of the plug is shaped to provide an oblique line 10 when inspected from the side.
  • the tear band 2 in the example illustrated extends for about 90° around the closure that is 45° on each side of a thumb tab 11 and the tear band 2 is connected to the cap part 1 by a weakened membrane 12 and to the anchor band 3 by a weakened membrane 13.
  • the weakened membrane 12 ends at each end 14 of the tear band 2 but the weakened membrane 13 extends on around the closure to the hinge 15 to form two arcuate weakened lines.
  • the anchor band 3 has a large main internal retai bead 16 and a smaller auxiliary bead 17.
  • the tear band In operation when it is desired to open a container which is closed by a closure as illustrated the tear band is torn away by seizing a finger grip 18 and pulling the band 2 around the closure in the usual way.
  • the band 2 has been torn to the end, 14 upward pressure is exerted on the tab 11 to push the cap part 1 away from the anchor band 3 so that the rest of the weakened line 13 between the end 14 of the tear band 2 and the hinge 15 is broken and the cap part 1 pivots upwardly on the hinge 15.
  • the arc of the tear band will be small e.g. 90° while with lower pressures the arc of the tear band may be longer.
  • tonic water with a pressure of about 120 p. s. i. has the highest pressure of any aerated soft drinks and to provide a hinged closure with a satisfactory safety margin for such a pressure we have found that the tear band should extend around the closure for not more than 45° on each side of the tab 11 i.e. 90° in all.
  • FIG 4 which plots 1bs/ins 2 of pressure within a container against the arcuate degrees of the tear band and shows that to reduce the tear band from substantially 360° to 180° does not make much improvement after which a quick improvement sets in until with a 90° tear band blowing open does not occur on tearing away until a pressure of about 145 p. s. i. within a container is reached.
  • the pressures plotted are averages obtained from ten samples each at 90°, 120 , 150°, 180°, and a complete tear band.
