Definitions

  • This invention relates to hand removable metal closure caps for containers and is particularly concerned with such caps provided with a ring shaped tearing ear adapted for reception of a persons finger.
  • Another object is to provide such closure caps having a new and improved ring shaped tearing ear.
  • a further object is to provide such closure caps having a ring shaped tearing ear specially formed to give maximum safety and comfort upon exertion of a finger applied tearing force.
  • FIG. 1 is a top plan view of the closure cap in accordance with the invention.
  • FIG. 2 is a vertical elevational view thereof
  • FIG. 3 is a bottom plan view of the ring shaped tear ing ear taken on lines 3-3 of FIG. 2 and looking in the direction of the arrows;
  • FIG. 4 is a vertical section taken on lines 4-4 of 3,446,382 Patented May 27, 1969 FIG. 3 and looking in the direction of the arrows; and
  • FIG. 5 is a vertical section taken on lines 5--5 of FIG. 3 and looking in the direction of the arrows.
  • the closure cap of the invention is formed out of lightweight sheet metal and is seen to comprise a disc like top portion 1 having a cylindrical skirt 2 depending therefrom and terminating in a substantially circular free edge 2a.
  • a tear strip 3 Integrally formed within the top 1 and skirt 2 of the cap is a tear strip 3 which is defined by a pair of tearing lines 4 and 5 weakened for that purpose such as by scoring.
  • the tear strip 3, as seen in FIG. 2 extends downwardly beyond the free edge 2a to form a short extension 6 of the skirt 2 and is bordered on either side at its departure from the skirt by an inverted V-shaped notch 7 which aids in the accurate commencement of the tearing of the tear strip at the point where the tear strip joins the cap skirt.
  • a ring shaped tearing ear Extending radially outwardly and downwardly at an approximate 15 degree angle is a ring shaped tearing ear generally indicated by the numeral 10.
  • the ring configuration is formed in a base panel extending away from the skirt extension 6 in a flat neck portion 11 which in turn merges into an annular base panel portion 12 having a convexly curved upper surface as seen in FIG. 4.
  • the base panel portion 12 is curled downwardly and radially inwardly at 13.
  • Extending from the outer curled edge 13 is an inner radially inwardly extending fold portion 14 terminating in a radially inwardly facing free edge 15.
  • the fold portion 14 terminates in side edges 17 at the point where the base panel portion 12 blends into neck portion 11.
  • the side edges 17 join the inwardly facing edge 15 at the arcuately shaped corners 17a.
  • the annular base panel portion 12 is curled downwardly and radially outwardly at 18 forming the inner peripheral edge of the ring.
  • Extending radially outwardly from the inner curled edge 18 is an outer fold portion 19 terminating in a radially outwardly facing free edge 20.
  • the inner curled edge 18 is larger than the outer curled edge 13 so that the outer fold portion 19 overlies a portion of the inner fold portion 14 and is slightly spaced therefrom.
  • the larger radius of the curved edge 18 provides a surface against which a substantial pulling force may 'be exerted with relative ease and comfort.
  • the improved form of the ring provides suflicient rigidity and strength to prevent damage or undue distortion thereof either during mechanical handling of the cap prior to application or during removal.
  • the ring form has sufiicient bulk to enable a substantial pull to be exerted thereon without discomfort.
  • the ring form its inner void space, indicated by numeral 21 in FIG. 4, sufficiently closed off so as to prevent the accumulation of dirt therein.
  • a hand removable lightweight metal closure cap comprising a disc-like top portion, a laterally depending skirt therearound terminating in a substantially circular free edge, a pair of weakened tearing lines extending across said cap skirt, and into said cap top portion, said lines defining a tear strip therebetween forming an integral part of said cap skirt and top portion, said tear strip extending downwardly away from said free edge in a short extension of said skirt and then extending radially outwardly away from said skirt in a ring shaped tearing ear, said car comprising a base panel commencing in a neck portion flaring outwardly in its extent from said skirt extension so as to merge into an annular base panel portion, a major portion of the outer periphery of said annular base panel portion being curled downwardly and terminating in a radially inwardly extending open fold portion, the inner periphery of said annular base portion being curled downwardly and terminating in a radially outwardly extending fold portion and said radially inwardly extending fold portion being vertical
