  • FIG. 4 illustrates the sealed package 3 with the closure cap 1 pressed into sealing engagement with the container 2 with the gasket 9 forming a seal with the container finish 10 and with the lugs 11 positioned beneath the bead 12 at the container rim.
  • a tamperproofing or tamper indicating band 13 is attached to the lower edge of the cap skirt 6 by a frangible connecting means in the position illustrated.
  • the band 13 when thus positioned prevents the above described removal action without first detaching at least a portion of the band. Any attempt to press or pry the cap 1 upwardly without removing the band 13 requires at least a portion of the band 13 to be pressed upwardly and thus torn clear of the cap skirt 6 in the manner illustrated in FIGS. 5 and 6.
  • the embodiment of the band 13 illustrated in FIGS. 1 through 6 is molded integrally with the plastic ring 5.
  • the frangible connection between the band 13 and the adjacent portions of the skirt 6 comprises a narrow slot 14 between the top of the band 13 and the bottom of the skirt 6 formed during the molding action and interrupted at a number of spaced points by coupling bridges 15 which hold the band 13 in place during sealing. shipment and storage.
  • the bridges 15 have sufficient strength for these purposes but are relatively thin in a circumferential direction, as illustrated, so that they are torn when any attempt is made to remove the closure cap 1 from the container 2.
  • the band 13 provides its tamper indicating function whether or not it engages the container 2 surface.
  • the band 13 may therefore be spaced from the container surface or proportioned to only lightly engage the surface. This facilitates cap application as no sealing operation other than the regular press-on sealing action is required.
  • the band 13 When the band 13 is positioned at or near the container 2 surface, it prevents an insect infestation of food packages.
  • the band 13 is torn clear using the accessible band ends at the slot 16.
  • the skirt 6 edge is then exposed so that it may be pressed or pryed upwardly to lift off the cap 1 as illus trated in FIGS. 5 and 6.
  • the tamper indicating band extends downwardly from the lower edge of the closure cap skirt and is lightly attached to the skirt so that any attempt to lift the cap from the container results in a release of the band from the cap skirt.
  • the closure cap 20 illustrated in FIGS. 7, 8 and 9, has an upper cap portion including a metal cover 21 and a plastic ring 22 generally similar to those described above.
  • the tamper indicating band 23 is releasably attached to the cap skirt 24 by a thin web portion 25 which comprises or resembles a score line releasably connecting the substantially thicker adjacent portions of the cap skirt 24 and the tamper indicating band 23.
  • the tamper indicating band 23 bars access to the lower edge of the cap skirt 24 thereby preventing cap removal without first removing the tamper indicating band 23.
  • a notch 26 is formed in the band 23 permitting the package user to grip an exposed end of the band 23 to tear it free from the cap 20.
  • the tamper indicating band 23 may be proportioned to take a position slightly outwardly of an adjacent bead 27 or other surface on the glass container 28.
  • the band 23 may also be proportioned to lightly engage the glass surface. No substantial engagement between the band 23 and the container is required and is avoided to assure that the band 23 is not unintentionally detached from the closure cap 20 during the normal sealing operation when the closure cap 20 is pressed downwardly onto the container 28.
  • FIGS. 10 through 14 illustrate another embodiment of the cap 30 which includes an integral pull tab 31 on the tamper indicating band 32.
  • the pull tab 31 is molded integrally with the outer plastic cap ring 33 so that it projects outwardly from the tamper indicating band 32 adjacent a slot 34 in the band 32.
  • the outer end of the pull tab 31 is releasably attached to an adjacent portion of the tamper indicating band 32 by a small plastic bridge 35.
  • a lift tab may be provided in the manner illustrated in the embodiment of FIGS. 15 through 18.
  • This embodiment of the closure cap 40 includes a metal cover 41 and a plastic ring 42 of the general form already described including a pull tab 43 to facilitate the removal of the tamper indicating band 44.
  • the opposite ends of the tamper indicating band 44 are spaced apart a sufficient distance to permit a lift tab 45 to be provided at the lower edge of the cap skirt portion 46.
  • the lift tab 45 is also formed as an integral portion of the molded plastic ring 42. It is hingedly connected by means of a plastic web 47 which permits the lift tab 45 to be pressed upwardly during cap removal in the manner illustrated in FIG. 17.
  • the opposite ends of the lift tab 45 are spaced from the ends of the tamper indicating band 44 by slots 48.
  • FIGS. 19 through 21 illustrate a closure cap 50in accordance with the present invention having a lift tab 51 and a pull tab 52 positioned adjacent to one another.
  • a lift tab 51 is integrally formed as a portion of the molded plastic ring 53 with its upper portion being hingedly connected at 54 to the cap skirt portion 55 permitting the lift tab 51 to be used to press the closure cap 50 off of the container 56.
  • the pull tab 52 for removing the tamper indicating band 57 is releasably connected to the lift tab 51 by means of one or more plastic bridges 58.
  • This bridge 58 prevents the lift tab 51 from being turned outwardly to its cap removing position without the pull tab 52 being torn clear of the lift tab 51 thereby breaking the bridge 58.
  • This embodiment of the closure cap also provides for a physical barrier for preventing insect infestation beneath the cap skirt 55. This barrier is provided by a light engagement between the lower edge of the band 57 and a generally vertical shoulder portion 59 provided on the sealed container 56.
