Definitions

  • This device generally relates to threaded tamper evident container closures, and to threaded tamper-evident closures having a push-pull resealable tamper evident pour spout.
  • the present invention provides an improved means of locking threaded tamper-evident closures to a bottle neck, by means of a uniquely shaped annular flange extending radially inward from the inner surface of the tamper-evident band attached to the bottom edge of the closure body.
  • This flange which can be continuous or segmented, forms an upwardly angled "hook" shaped surface for engaging the sealing flange on the bottle neck.
  • the hook-like flange has a reverse basis that allows it to slide past the bottle neck sealing flange as the cap is snapped downward onto the container during installation. The hook-shaped flange then
  • the hook-shaped flange of the present invention can optionally be configured with a plurality of fins or gussets extending upwardly from and in a direction substantially perpendicular to the sealing surface of the flange. The purpose of the fins or gussets is to assist in breaking and dislodging the tamper- evident band from the remainder of the closure by engaging the exterior surface of the bottle neck as the tamper-evident seal is being broken.
  • the present invention provides a novel configuration for protecting the integrity of frangible elements during installation of threaded tamper-evident closures.
  • a plurality of elevated areas extend upwardly from the tamper-evident band in spaced relation to the bottom edge of the closure body. The purpose of these elevated areas is to support the tamper evident band in resisting vertical movement imparted by insertion of the closure on the bottle neck, thereby protecting the frangible elements during assembly.
  • the frangible elements connecting the tamper-evident band to the lower edge of the closure body may be configured to extend from these elevated areas as well as the non-elevated areas of the tamper-evident band.
  • frangible elements to the elevated areas of the tamper-evident band is to assist in preventing axial misalignment of the tamper-evident band relative to the annular depending skirt portion of the closure upon subjecting the closure to torquing forces during assembly to the container neck.
  • Prior art threaded push-pull pour spout closures providing tamper evidency and having tamper evident pour spouts have not always been leak proof at spout closure interface.
  • prior art push-pull pour spout closures that are reusable do not provide effective sealing at the juncture between the spout opening and the plug positioned in the opening when the spout is closed. Because of the very small diameter of the opening and the concern for safety, it is not possible to add non- integrated sealing means.
  • the present invention solves this problem by utilizing a closure plug which combines a circular closure disk with an integral annular skirt depending from the periphery of the disk thereby defining a hollow cavity for the plug interior and increasing the structural flexibility of the plug.
  • the increased structural flexibility provided by the hollow cavity causes inward deformation of the plug skirt upon engagement with annular flanges integrated into the periphery of the spout closure central opening to create a form-fitting leak tight seal.
  • a plurality of circumferentially spaced dimples optionally extend from the exterior wall of the pour spout. These dimples engage vertically spaced inturned annular flanges on the interior surface of the spout closure to facilitate breaking the frangible elements connecting the tamper evident band to the push- pull pour spout closure.
  • the present invention also optionally provides a tamper-evident dust cover which encloses the push-pull pour spout closure when inserted on the container.
  • the dust cover is provided with a tamper-evident sealing band which remains intact upon initial installation of the dust cover onto the container and which is broken when the dust cover is initially disturbed.
  • the purpose of the dust cover is to provide an indication of whether the push-pull pour spout closure has been exposed subsequent to the sealing of the container. Accordingly, it is an object of the present invention to provide a threaded tamper- evident closure having an annular hook-shaped flange extending radially inward from the inner surface of the tamper-evident band attached to the bottom edge of the closure body, for

Abstract

La présente invention se rapporte de manière générale à une fermeture filetée inviolable ayant une bride (16) annulaire recourbée en crochet, disposée radialement vers l'intérieur, en saillie à partir d'une surface interne de la bande (15) d'inviolabilité fixée au bord inférieur du corps de la fermeture. La bride recourbée en crochet peut être continue ou segmentée et elle forme une surface en angle dirigée vers le haut destinée à entrer en contact avec la bride d'étanchéité (17) disposée sur le goulot de la bouteille. Une pluralité de zones surélevées (35) font saillie vers le haut à partir de la bande d'inviolabilité disposée à distance du bord inférieur du corps de la fermeture. Les éléments cassants (14) reliant la bande d'inviolabilité au bord inférieur de la bride annulaire associée à la fermeture peuvent être conçus de façon à faire saillie à partir de ces zones surélevées comme des zones non surélevées de la bande d'inviolabilité. Une seconde réalisation préférée de la présente invention concerne une fermeture en plastique filetée inviolable ayant une bande d'inviolabilité comportant les caractéristiques décrites ci-dessus, et conçue pour être utilisée avec un bec verseur (20) refermable de type 'tire-pousse' et inviolable qui est sensiblement étanche. La présente invention se rapporte en outre à un couvercle anti-poussière (90) inviolable qui recouvre la fermeture à bec verseur de type 'tire-pousse' lorsqu'il est placé sur le contenant. Ce couvercle anti-poussière est équipé d'une bande d'étanchéité (91) inviolable à rochet qui reste intacte lors de l'installation initiale du couvercle anti-poussière sur le contenant et qui est brisée lorsque ce couvercle anti-poussière est manipulé pour la première fois.
