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
- annular flange to prevent removal of the closure body from a bottle neck while the tamper
- closure with a reusable push-pull pour spout having a plurality of fins or gussets extending upwardly from and in a direction substantially perpendicular to the sealing surface of an annular hook-shaped flange, to assist in breaking and dislodging the tamper-evident band from the remainder of the closure body.
- a first preferred embodiment of the present invention generally provides 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.
- the hook-shaped flange can be continuous or segmented and forms an upwardly angled surface for engaging the sealing flange on the bottle neck.
- the edge of the flange preferably lies at an angle with a plane normal to the inner surface of the tamper-evident band, thereby defining a grooved "hook" which slides over the locking flange on the bottle neck when the closure is placed on the container but which engages and locks the closure to the container neck when removal of the closure is attempted with the tamper-evident band intact.
- the hook-shaped flange 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.
- a plurality of elevated areas extend upwardly from the tamper-evident band in spaced relation to the bottom edge of the closure body.
- a second preferred embodiment of the present invention provides a threaded tamper- evident plastic closure having a tamper-evident band containing the above -described features, for use with a tamper evident push-pull resealable pour spout which is substantially leak proof.
- the push-pull pour spout has an opening which is partially closed by a second top having a secondary opening therein and a plug spaced thereabove with upwardly angled legs formed integrally with the closure.
- the plug takes the form of a circular closure disk having an integral annular skirt depending from the periphery of the disk that attaches the plug to the angular legs thereby defining a hollow cavity for the plug interior and increasing the structural flexibility of the plug.
- annular flanges Integrated into the periphery of the secondary opening is at least one and preferably two annular flanges which engage the plug skirt when the secondary opening is closed to seal the spout.
- the annular flanges cause inward deformation of the plug skirt upon engagement to create a form-fitting leak proof 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 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.

- locking projections 16 are circumferentially spaced about the inner surface of said tamper evident ring 15 and are positioned so that they are engageable under an annular locking flange 17 to lock the closure on a bottle neck 18 as seen in Figure 5 of the drawings.
- projections 16 comprise edges 16a defining grooves 16b formed on radially upwardly extending annular flanges 16c.
- Flanges 16c are preferably discontinuous but can be continuous.
- Edge 16a and groove 16b provide a "hook" shape for engaging the annular locking flange 17 which has a radius substantially the same as groove 16b.
- flange 16c lies at an angle with a plane normal to the inner surface of the tamper- evident band 15, thereby defining a grooved "hook” with a reverse basis allowing flange 16c to slide over the locking flange 17 on the bottle neck 18 when the closure is placed on the container but which engages and locks the closure to the container when removal of the
- the aforementioned angle may vary over the surface of flange 16c such that at least a portion of the flange surface lies substantially parallel to the interior surface of the tamper indicating band 15.
- This flanged edge and groove configuration 16a- 16c may be positioned at any
- the hook-shaped flange 16c of the present invention can optionally be configured with a plurality of fins or gussets 10 extending upwardly from and in a direction substantially pe ⁇ endicular to the sealing surface of the flange.
- the pu ⁇ ose of the fins or gussets 10 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
- the tamper-evident band 15 has a series of circumferentially spaced elevated bridge areas 35 extending towards the closure depending annular skirt 13. Each of the elevated bridge areas 35 defines a
