Definitions

  • a closure cap for threaded containers which includes a tamperproofing means to indicate unauthorized tampering with or removal of the closure cap from the sealed container.
  • the closure cap is of composite construction having a metal disc-like top fitted into a molded plastic ring or skirt.
  • the plastic skirt includes container engaging threads positioned above a tear-off tamper indicatingband.
  • the tamper indicating band has integral molded pawl members which engage lugs or ratchet teeth on the container so that the tamperproofing strip must be removed before the closure cap can be turned off of the container. Should there be an unauthorized attempt to open the container, the tamperproofing strip will be torn off as the closure is turned on the container.
  • the present invention relates to an improved tamperproof closure cap with a tamper indicating band and more particularly to an improved tamperproof cap which may be used for a hermetic seal and where the tamper indication is obtained before the hermetic seal is broken.
  • caps having a tearoff band formed on the cap which must be removed before cap removal or which is visably damaged as soon as the cap is turned off.
  • Such caps have been used for beverages packed under pressure as well as for a variety of other products which have their head space at atmospheric pressure.
  • These prior caps include metal caps with a tear-off band and a number of plastic caps including integrally molded tear-off bands. Neither of these present designs are particularly well suited for, use with vacuum seals since it is possible to rotate the caps of these designs a sufficient amount to destroy the vac-, uum seal before the tamper indicating action occurs.
  • the closure cap of the present invention overcomes this drawback and it also provides a cap for use on molded glass containers having an easily formed glass finish.
  • the cap also minimizes sealing. problems by being easily hoppered, fed to sealing machines, and applied and turned to its fully sealed position. Additionally, a cap is provided which combines these advantages with a capacity for automatic package checking including dud detection.
  • an object of the present invention is to provide an improved tamperproof cap.
  • Another object of the present invention is to provide an improved tamperproof cap for use on a glass finish which requires no sharp corners or complex radial projections.
  • Another object of the invention is to provide a tamperproof closure which is easily hoppered and fed and sealed on containers using high speed automatic sealing machinery.
  • Another object of the invention is to provide an improved tamperproof closure cap where tamper indication results prior to the loss of a vacuum seal.
  • Another object of the invention is to provide an improved tamperproof closure cap having an insect infestation resistant skirt.
  • Another object of the invention is to provide a tamperproof closure cap for a vacuum sealed package for use with automatic dud detectors.
  • FIG. 1 is a perspective view of a preferred embodiment of the improved sealed package.
  • FIG. 2 is a perspective view corresponding to FIG. 1 illustrating a tamperproofing strip partially removed.
  • FIG. 3 is a bottom plan view of the preferred embodiment of the closure cap.
  • FIG. 4 is a horizontal sectional view taken through the container glass finish illustrating the positions of the cap engaging lugs.
  • FIGS. 5 and 6 are vertical sectional views illustrating two positions of the closure cap during cap application and sealing.
  • FIG. 7 is a vertical sectional view of the sealed package taken along line 77 on FIG. 1.
  • FIG. 8 is a vertical sectional view of the sealed package with the tamperproofing strip removed.
  • FIG. 9 is a fragmentary horizontal sectional view illustrating the details of the preferred embodiment of the cap pawl and the cooperating container lug.
  • FIG. 10 is a fragmentary horizontal sectional view of the pawl and lug taken along line 10-10 on FIG. 7.
  • the closure cap of the present invention which will now be described in detail with reference to the figures provides the tamperproof closure cap for application to glass containers and which is particularly adapted for use with hermetically sealed glass containers.
  • a glass finish and a cooperating plastic cap skirt are provided to give the tamper indicating action through the use of a tear strip and a separate disc-shaped cover is provided on the cap for forming the hermetic seal in such a way that the tamper indication is operative before the hermetic seal is destroyed.
  • This desirable result has not been available in prior tamperproofing designs where a significant amount of cap rotation is possible before the tamper indication is given. Such partial rotation before tamper indication would not be objectionable in many packages but cannot be tolerated in hermetically sealed packages, such as food packages, where the loss of vacuum would result in damage to the packaged product.
  • the preferred closure cap 1 of this invention includes a separate metal disc or cover 2 which is preferably fonned of metal such as tin plate or aluminum.
  • the cover 2 includes a central stacking panel 3 and a raised dud detection button 4 if desired.
  • the cover 2 is formed with a downwardly facing channel 5 and an inwardly curled edge 6 for receiving a suitable plastisol or other gasket 7.
  • the cover 2 is fitted into the upper portion of a plastic ring 8 having container engaging threads 9 molded on its inner surface and having a flange-like marginal annular cover 10.
  • An annular groove 11 just beneath the ring cover 10 is formed in the plastic ring 8 for receiving the outer edge 5 of the cap cover 2.
  • a tamper indicating tear-off band 12 is molded as an integral lower portion of the cap skirt 13 below the container engaging threads 9. This band 12 is connected to adjacent portions of the skirt by a frangible coupling such as a thin connecting web 14 which may be readily torn when the band 12 is removed from the cap 1 by the users gripping the tear-off tab 15 formed on the end of the band 12 and tearing the band 12 from the remainder of the cap skirt 13.
  • the tear-off band 12 comprises an annular outer section 15 having its upper portion attached to the remainder of the cap skirt at 14 and having a number of resilient integral, radially inwardly projecting fins or pawls 17 formed therein.
  • These pawls 17, as illustrated in detail in FIGS. 9 and 10, are proportioned to spring inwardly to engage a flat forward edge 18 of a container lug 19 when a fully sealed cap 1 is turned off of a sealed container 1.
  • the preferred container 20 finish, as seen in FIG. 4 and in FIGS.
  • lugs 19 are provided for action with eight cap pawls 17 located on the tear-off band 12.
  • cap pawls 17 located on the tear-off band 12.
  • a tear-off band 12 destroying action would occur after no more than a 45 reverse turn of the closure cap 1.
  • the cap 1 is in the position illustrated in FIG. 10 where the pawl 17 prevents further reverse movement of the cap 1 without a destruction of or an intentional removal of the tear-off band 12.
  • Other spacing arrangements of lugs and pawls can be used to get appropriate control of the reverse turning for differing fractions of cap revolutions.
  • the pawls 17 are preferably molded as integralporr tions of the cap skirt band 12 with each having an inward slant as illustrated in FIGS. 3 and 10. This gives the pawls 17 a resilient action insuring a firm and operative locking engagement between the pawls 17 and the forward edges 18 of the glass container lugs 19 even where the lugs 19 may have a slightly rounded surface or corner such as results during the molding of glass finishes.
  • FIG. 5 illustrates the improved cap 1 as it is first lightly dropped or applied from a chute or cap applicator onto the container 1 finish. In this position, the generally circular upper surface of the transfer bead 21 evenly engages the spaced pawl members 17 so that the cap 1 is level on the container 20.
  • the cap cover 2 is pressed tightly against the bead 26 on the container rim 22 to form a seal as the cap pawls 17 are moved below the transfer bead 21 with the cap. pawls 17 springing inwardly for the above described.
  • the preferred embodiment of the tear-off band 12, as described above, has its top connected to the cap the pull-down tab 15 prevents it from interferingwith the high speed hoppering, feeding, and cap application operations typical of high speed sealing lines so that the cap 1 may be handled in the same manner as closure 1 caps not employing a pull-down tab.
  • FIGS. 7 and 8 also illustrate a close positioning of the inner surfaces of the plastic cap skirt and the ad-v jacent finish of the glass container 20 so that there is only a minimal void space between the closure and the, container thereby reducing the possibility of trapped product being present at the cap and container threads.
  • the separate metal cover 2 of the preferred form described above, provides for a closure cap 1 with high abuse resistance.
  • the retentionof a hermetic orvac-. uum seal during an initial backing-off of the closure cap 1 during possible tampering with a sealed package has already been discussed above.
  • the separate metal cap cover 2 also acts to retain a hermetic seal even though, I
  • the closure 1 of the sealed package is inadvertently subjected to various forms of abuse, such as where the cap is struck or placed under uneven pressure or storage.
  • the upwardly domed flip panel 4 may be provided in the metal cover 2 for providing the usual vacuum indicator. The flip panel 4 moves downwardly as the result of the vacuum in the head space of the sealed container and pops upwardly with an audible click when the seal is broken.
  • an improved composite tamperproof closure cap' is provided.
  • the closure is particu larly useful for glass containers and with vacuum sealed packages.
  • a reliable and positive tamper indicating means is provided having a high degree of abuse resistance so that the vacuum seal is protected against package abuse and is not lost without an indicationzof the tampering which caused the vacuum loss.
  • the closure cap also permits automatic dud detection when used for vacuum sealing and includes a flip panel for audible vacuum indication.
  • the improved cap construction resists infiltration and trapped product accumulation.
  • An improved sealed tamperproof package comprising the combination of:
  • said container having closure engaging threads adjacent its rim
  • annular transfer bead extending outwardly from the upper portion of the container below said cap engaging threads and having a smooth surface and being positioned below said container threads for engaging all of the cap pawls as the cap is turned onto the container and prior to any pawl engaging one of said container lugs;
  • a composite closure cap positioned on said container comprising the combination of:
  • plastic ring having an annular cover portion and a depending skirt
  • a tear-off band formed integrally with and extending downwardly from the lower edge of said skirt and being connected thereto by a frangible connection;
  • said lugs on said container include a flat, radially directed, pawl engaging surface for engaging a corresponding flat surface on the container lugs and also include an inwardly slanted surface for permitting the pawls to pass over the lugs during cap application.
  • An improved vacuum sealed tamperproof package comprising the combination of:
  • said container having closure engaging threads adjacent its rim
  • annular transfer bead extending outwardly from the upper portion of the container below said cap engaging threads and having a smooth surface
  • a composite closure cap positioned on said container comprising the combination of:
  • plastic ring having an annular cover portion and a depending skirt
