Tamper evident band with hook
A tamper indicating closure includes a cap having a top and skirt portion. A frangible connection connects an anti-tamper band with the skirt. The anti-tamper band includes a main body and a foldable portion hingably connected thereto. The foldable portion is foldable so that it is disposed within the volume defined by the main body. The foldable portion further comprises an edge for engaging the shoulder of a container at a recess below the shoulder and a plurality of tabs for engaging the shoulder to prevent “tiring off” of the anti-tamper band.

FIELD OF THE INVENTIONGenerally, the present invention relates to the field of container closures. More particularly, the present invention relates to closures having a tamper-indicating band.
BACKGROUND OF THE INVENTIONConsumers rely on container closures to protect many everyday goods ranging from food to medicine. While numerous types of tamper-indicating closures exist, a particularly common type of closure comprises a closure connected to a tamper-indicating band via a frangible connection, with the closure being applied to the threaded finish of the container. This type of closure often relies on a portion of the container to restrain the tamper-indicating band when the cap is removed, causing the frangible connection to break and leaving the tamper-indicating band on the container in a retained engagement with the container finish. Thus, even if the closure is replaced back on the container, a user is able to determine that the container has been opened because the frangible connection of the closure with the tamper band has been broken.
This type of tamper-indicating system relies on the frangible connection being broken and on the tamper-indicating band remaining on the container. However, conventional closures suffer from “tiring off,” where the tamper-indicating band is essentially peeled or slipped off the container. This is similar to the manner in which a tire is removed from a rim. This defect defeats or at least detracts from or reduces the tamper-indicating ability of the closure band. Thus, there is a need for an improved closure providing a frangible connection between a tamper-indicating band and a cap that is resistant to tiring off and other tamper-indication defeating mechanisms.
SUMMARY OF THE INVENTIONVarious embodiments of the invention relate to a closure providing a frangible connection between a tamper-indicating band and the lower end of a closure sidewall skirt, with the closure being resistant to tiring off and other tamper-indication defeating mechanisms.
The closure comprises a top portion that is connected to a skirt. An anti-tamper band is frangibly connected to the skirt. The anti-tamper band comprises a main body and a foldable band connected to the main body opposite the cap, such that the band is continuous along the entire perimeter of the main body. The foldable band is connected to the main body via a hinge. The foldable band has an unfolded state, where it extends substantially linearly from the main body, and a folded state. In the folded state, the band is bent about the hinge, forming an acute angle with the main body and being substantially within the volume defined by the main body. The foldable band further comprises a plurality of flexible tabs extending from within the foldable band. The foldable band includes an end opposite the hinge for engaging a portion of the container. The tabs further engage the container to secure the anti-tamper band to the container when the cap is removed.
These and other advantages and features of the invention, together with the organization and manner of operation thereof, will become apparent from the following detailed description when taken in conjunction with the accompanying drawings, wherein like elements have like numerals throughout the several drawings described below.
The present invention comprises a closure 100 for sealing an article and providing tamper evidence. As shown in
As referenced above, the closure 100 further includes an anti-tamper band 114. The anti-tamper band 114 is removably connected to the skirt 112. For example, the anti-tamper band 114 may be connected to the skirt via a frangible connection 116. In an exemplary embodiment, the anti-tamper band 114 is connected to the skirt 112 at an end opposite the top portion 110.
The anti-tamper band 114 includes a main body 118 and a foldable or “J” band 120. The main body 118 is attached via the frangible connection 116 to the skirt 112. A foldable band 120 is attached via a hinge 121 to the main body opposite the skirt 112. The hinge 121 may exert a bias on the foldable band 120. The foldable band 120 is pivotable about this hinge 121. The foldable band 120 has an unfolded state and a folded state. The closure 100 may be such that the foldable band 120 extends from the main body 118 in line with the main body 118 in an unfolded state.
As shown in
As shown in
The foldable band 120 further includes one or more tabs 122. In an exemplary embodiment, the tabs 122 are embedded into the structure of the foldable band 120. The tabs 122 may be integral with the foldable band 120 such that band 120, tabs 122, and main body 118 comprise a single molded component (the anti-tamper band 114). The tabs 122 extend from the foldable band 120, forming an extension there from. The tabs 122 are positioned substantially proximate the edge of the foldable band 120 which is farthest from the article 103 when the closure 100 is applied and the foldable band 120 is positioned in its folded state. In one embodiment, the tabs 122 flex about a pivot 127, such as a thinned portion just above the foldable band 120. The tabs 122 engage the protruding edge 131 of the shoulder 128 (
In an exemplary embodiment, the tabs 122 are flexible such that they may bend relative to the foldable band 120. As can be seen in
When the cap 101 is removed, as illustrated in
