Definitions

  • the present invention relates to closures for containers, and more particularly to tamper-evident closures for containers.
  • a further problem is the poor visibility of the status of the tamper-evident features, with the consequence that a consumer may not discern that the seal of the container has been broken.
  • Tamper-evident band design on most closures includes an interface between the container neck and the tamper band. Often upon opening and removal of the closure the tamper-evident band does not drop away from the closure body but remains by means of interference between the tamper-evidence band and the container neck held on the neck in a similar position to the tamper band on an un-opened package or in the case of malicious tampering a container may be opened and contaminants introduced and the closure replaced and the tamper-evidence band pushed back into close proximity to the closure to give the appearance of an un-opened package.
  • One aspect of the present invention deals especially with the need for a proper relationship between sealing means and tamper-evidence means such that the tamper-evidence means operates prior to the seal being breached. This avoids the possibility apparent with many so-called tamper-evident closures whereby by malicious tampering or inappropriate application torque and/or relaxation of the closure causing the seal between closure and container neck to be breached without the tamper-evidence means operating and allowing the contents to be degraded by action of atmosphere or the malicious introduction of contaminants.
  • a further aspect of the present invention provides a tamper-evident closure for a container with tamper-evident means and means of dispensing one or more additives into the container and a tamper-proof cover to protect additive dispensing means.
  • a further aspect of the present invention provides a tamper-evident closure for a container with tamper-evident means and a dispensing means for dispensing the contents of the container in a controlled or limited manner, and a re-usable tamper proof cover for said dispensing means.

  • Face 18 a is of a dimension J which is equal to or less than the distance that the tamper bead 16 projects beyond the external surface of the container neck.
  • Face 18 a is designed to interact with tabs 122 on closure 100 such that upon rotation of the closure, the engagement face 124 of tab 122 engages with the angled engagement face 18 a .
  • the tab 120 Upon further rotation of the closure, the tab 120 is driven downwardly along the angled face 18 a , thereby placing stress on the frangible ribs 116 and facilitating the severance of the frangible ribs 116 , thus promoting early tamper-evidence operation by opening a discernable gap between the lower edge of the skirt 104 and the tamper evident band 110 .
  • FIG. 2 depicts an alternative embodiment wherein the face 18 a includes a portion 18 a ′ of varying angle with respect to the plane of the lower surface of the tamper-evident bead 16 .
  • the face has an initial curved section which provides a gently increasing angle with respect to the lower surface of the bead.

  • the face 18 a has an initial surface angled with respect to the plane of the lower surface of the tamper-evident bead 16 , followed by one or more further surfaces of increasing angle with respect to the plane of the lower surface of the tamper-evident bead 16 .
  • FIG. 4 shows sealing means in sealing engagement with the external wall of container neck 10 .
  • the distance between the underside face of container tamper-evident bead 16 and the projection face 18 m and the extent and location of the progressively ramped portion 18 a ′ of projection face 18 a are designed to take into account:
  • frangible ribs 116 it is possible to reduce the force necessary to initially stretch and break the first frangible ribs by selectively designing one or more of the frangible ribs 116 be weakened. It is possible to predetermine which ribs will be first to advance to projections 18 upon removal of the closure and therefore the weakened frangible ribs can be located as to be first to be stretched by the downwards urging along projection face 18 a.
  • Face 18 b is of a dimension K which at least exceeds the width of the space 122 c between the engagement portions 122 of the tamper-evident band 110 so that the free ends 126 of the tabs 122 will be retained below the edge 18 m of the projection 18 , thereby making a more visible gap between the severed tamper-evident band 110 and the closure skirt 104 .
  • Face 18 c has a ramped surface so as to minimise interference and enable the tabs 122 to pass easily over the projections upon the initial application of the closure to the neck of the container.
  • the closure can be designed to be applied by axial movement (for example by using a multiple thread) rather than by rotation.
  • FIG. 7 is a partial perspective cross-sectional view of a preferred embodiment of the tamper-evident band 110 prior to application to a container.
  • the tamper-evident band 110 depends from the lower face of the skirt of the closure (not depicted) by means of a series of ribs 116 which form a frangible section.
  • the band includes an annular wall 120 and a plurality of circumferentially spaced tabs 122 connected to an inner surface of the annular wall.

  • the engagement surfaces 124 of the tabs 122 have an angle corresponding to the angled faces 18 a of the projections 18 so that engagement surfaces 124 tend to make contact with faces 18 a over a greater portion of the engagement surface 124 . This tends to avoid the curling or folding of the junction of surface 124 and 124 a thereby assisting in directing engagement surface 124 a downwards along angled faces 18 a.

  • Recesses 122 a of width R and depth S are provided between each tab 122 .
  • the depth ‘S’ is preferably such that during application of the closure to the container the hoop strength existing in the continuous annular portion of the band along line extending from the bases 122 e of recess 122 a is sufficiently reduced to enable flexing along the line of the bases 122 e of the recess 122 a to facilitate a more easy application of the closure to the container.
  • the depth ‘S’ of the recess 122 a is preferably greater than the distance between dotted lines W and X of FIG. 1 thereby allowing the free end 124 of tabs 122 , at least when adjacent to angled engagement faces 18 a , to remain in close proximity to the container neck and allow the free end of closure engagement surfaces 124 a to engage angled engagement faces 18 a .
  • the free end of engagement surfaces 124 a are driven downwards along angled engagement faces 18 a thereby inducing axial stress in the frangible ribs 116 resulting in breakage of one or more of the ribs and promoting early separation of the tamper-evident band 110 from closure 100 .
  • the continuous annular portion of the engagement portions 122 of the tamper-evident band 110 along the line extending from the bases 122 e of recess 122 a enhances the effectiveness of contact between said engagement surfaces 124 a and said angled engagement faces 18 a by assisting to maintain the location of engagement surface 124 a
  • the ramped upper shoulder of the tamper-evident bead 16 urges the tamper-evident bead engagement portion 122 of the tamper-evident band 110 against the inside wall of the tamper-evident band so that the tamper-evident band 110 may pass over the tamper-evident bead 16 and the ramped surfaces 18 c of projections 18 urge the free edges of the upper regions of engagement portions 122 against the inside wall of said tamper-evident band 110 so that the said engagement portions of the tamper-evident band 110 may pass over the projections 18 .

  • the free end of the tamper band 40 comes into contact with the underside of the container tamper bead 37 and the axial force applied is transmitted through the engagement portion 40 to the body of the tamper band 35 .
  • the force may be expressed as operating initially on a vector approximately through the line F. However, part of the force will be directed by the geometry and relative positions of the respective features 41 , 42 , 43 , in the direction K which will cause the band 35 to deform outwardly and thereby move hinge point 41 outwards. This serves to increase the angle of the engagement portion 40 and cause an increase in the force acting in the direction K and the decrease acting in the direction L.
  • engagement portion 40 may be deformed so as to invert without severing the tamper band from the closure, thereby defeating the intended tamper-evidence feature of the closure 40 .
  • FIG. 24 is taken from U.S. Pat. No. 6,640,988, the contents of which are hereby incorporated into this specification by way of cross-reference.
  • the engagement portion 40 consists of a number of separate elements hinged from a lower end or hinge point 41 .
  • This arrangement affords many advantages over the prior art such as U.S. Pat. No. 5,755,347 in that there is no hoop strength in the engagement portion of the tamper band to be overcome in the application of the closure.
  • This aspect of the invention provides a closure with a tamper band having more than one engagement portion 40 with a removal force vector angle closer to direction L so as to reduce the propensity of the tamper band 35 to deform outwardly when removal force is applied to the engagement portions 40 .
  • This is achieved by locating the hinge point 41 closure to the axis of the closure. Such relocation is brought about by thickening the tamper band 35 at the hinge point 41 . In doing so, the force vector angle is reduced, causing more of the removal force to operate in the direction L and less to operate in direction K.
  • thickening the band facilitates resistance to outward deformation which assists in maintaining the position of hinge point 41 , thus maintaining maximum force vector in direction L.
  • the thinner portion of the band above hinge point 41 leaves an area into which the free of engagement portion 40 can flex during application as the engagement portion 40 passes over the container tamper bead 37 .
  • the force vector operating upon removal at hinge point 41 to stretch the band 35 is reduced by about 60% (reduced from about 15 degrees to about 5 degrees); and the increase in hoop strength by thickening the lower portion of the band 35 will further contribute to resisting stretching of the band upon removal. Both of these changes act together to ensure that the hinge point 41 is more resistant to outward movement under the stress of removal, thus ensuring that the engagement portions 40 are held in place to effect separation of the tamper band from the closure.
