Definitions

  • the present invention relates generally to a polymeric closure for a package. More specifically, the present invention relates to a tethered one-piece polymeric closure to assist in preventing or inhibiting the closure from being separated from the container.
  • Polymeric closures have been used in many applications over the years in conjunction with containers.
  • One type of polymeric closure that has been used with containers is a tamper-evident polymeric closure. Tamper-evident closures are used to prevent or inhibit tampering by providing a visible indication to a user if the closure has been opened. This visual indication typically divides the closure into two separate components after the tamper-evident feature has been broken. The top portion of the closure is then removed from the container to gain access to the contents of the containers.
  • One drawback of tamper-evident closures being separated into two individual components is that the top portion may not be recycled along with the remainder of the closure and container. This scenario raises potential environmental concerns with so many containers having tamper-evident features that can be separated into two individual components.
  • a one-piece closure comprises a first closure portion and a second closure portion.
  • the first closure portion includes a polymeric top wall portion and a polymeric annular skirt portion depending from the polymeric top wall portion.
  • the annular skirt portion includes an internal thread formation for mating engagement with an external thread formation of a container.
  • the polymeric annular skirt portion includes a first frangible connection that partially detachably connects to a first section and a second section of the polymeric annular skirt portion.
  • the second closure portion includes a polymeric tamper-evident band. The tamper-evident band depends from and is partially detachably connected to the polymeric annular skirt portion by a second frangible connection.

  • the second closure lead 38 begins near the polymeric top wall portion 12 at a first position (not shown in FIG. 1B ) and extends in a helical fashion to a second position (not shown in FIG. 1B ) closer to the tamper-evident band 18.
  • the first and second closure leads 36, 38 are referred collectively as a double lead closure thread.
  • Each of the first and second closure leads 36, 38 is continuous.
  • the first positions of the first and second closure leads 36, 38 are located roughly 180 degrees apart from each other and, thus, begin on generally opposing sides of the closure 10.
  • first and second closure leads may be discontinuous. It is also contemplated that the internal thread formation of the closure may differ from a helical thread formation. It is also contemplated that other internal thread formations may be used in the closure.
  • the polymeric continuous plug seal 16 of FIG. 1B depends from the polymeric top wall portion 12.
  • the continuous plug seal 16 is spaced from an interior surface of the polymeric annular skirt portion 14.

  • the polymeric tamper-evident band 18 of the closure 10 is located at the bottom thereof (i.e., an end opposite of the polymeric top wall portion 12).
  • the tamper-evident band 18 depends from and is partially detachably connected to the annular skirt portion 14 by the second frangible connection 24.
  • the tamper-evident band 18 works in conjunction with the container to indicate to a user that the contents of the container may have been accessed. More specifically, the tamper-evident band 18 is designed to partially separate from the annular skirt portion 14 if a user opens the package and gains access to the container as shown, for example, in FIGS. 2A and 2B .
  • the first and second frangible connections 22, 24 may be formed by molded-in-bridges in one embodiment.
  • the molded-in-bridges are typically formed using a feature in the mold.
