Description

CLOSURE INDICATING IMPROPER HANDLING WITH FOLDING TONGUE FIELD OF THE INVENTION The present invention is concerned with container closures and in particular with closures that include indication of tampering such as an indication tamper band.

BACKGROUND OF THE INVENTION Locks that indicate tampering for bottles and other containers are designed to indicate to the consumer when the container has been opened or otherwise tampered with improperly. Known tampering closures commonly include a flat circular closure and an annular skirt that is downwardly dependent on the outer rim of the top or remote closure portion. The inner surface of the skirt portion includes threads that interact with a threaded portion of the container neck to retain the closure on the container. Locks that indicate tampering also commonly include a tamper indicating band connected to the bottom of the skirt along a frangible line or gasket. The band indicating tampering is in general an annular element which may have a plurality of tabs extending upwards and downwards which are retained under an annular shoulder in the container neck. With the closure being removed from the container for the first time, the tabs come in contact with the shoulder and cause the tamper evident band to separate from the skirt along the frangible line with many closures indicating tampering. known, the upper part of the closure, skirt and band indicating tampering are integrally formed.However, due to the complexity and shape of the tamper indicating closure, the tabs must frequently be formed facing down and then folded upwards In some cases, this manufacturing method may require overheating of the closure to set the tabs in an upward and inward position, which adds to the time and costs of manufacturing.In an effort to avoid this problem, some closures are formed With collapsible arrangements, known folding arrangements, however, are frequently formed as folding bands Units encompassing the closure circumference, instead of the individual tabs (see, for example, US Pat. No. 4,546,892 issued to Couput). These folding strips and similar arrangements in which the folding strips are broken into large segments, can be difficult to fold. To the extent that folding is obtained, the folding process can bend and deform the relatively large segments and bands, decreasing the structural integrity and hence the reliability of the mechanism that indicates tampering. Other collapsible closures group a plurality of tablets with joining elements (see, for example, US Patent No. 4,981,230 issued to Marshall et al.). These groups may suffer from the same deficiencies as the folding bands described above. Alternatively, the groups may require relatively weak bridges which can be broken, decreasing again the structural integrity and reliability of the mechanism.

DETAILED DESCRIPTION Figure 1 illustrates a closure 20 according to an exemplary embodiment of the present invention, which includes a plurality of tabs 34 whose geometric shape allows each tab 34 to be folded upward to a stable position without requiring reheating, reworking or another refragmented manner of the tongue 34. In general, the closure 20 includes an upper wall 22, a skirt 24 and a band 30 indicating tampering. The upper wall 22 may be circular in shape, although any suitable shape may be used. The closure 20 also includes a skirt 24, for example an annular skirt 24, dependent on the upper wall 22. In the illustrated embodiment, the skirt 24 depends on the outer edge of the upper wall 22, but the upper wall 22 can extend further beyond skirt 24 if desired. The skirt 24 includes for example at least one internal thread 26 cooperating with an external thread 14 on the container 10 (shown in Figure 7) to retain the closure 20 in the container 10. While the embodiment illustrated includes internal threads and external 26 'and 14, any appropriate retention formation, such as attachment ears, can be provided. The terms "internal threading" and "external threading" must be interpreted to include these alternative formations. The tamper indicating band 30 is connected to the skirt 24 along a frangible line 28. The tamper indicating band 30 can be connected to the skirt 24 at the bottom of the skirt 24, as illustrated in Figure 1. frangible line 28 can include any type of frangible formation, for example a scoring line along the entire circumference or a series of slagging lines each encompassing a circumference segment. In the illustrated embodiment, the frangible line 28 includes a plurality of bridges 29. The bridges 29 can be formed during the original molding of the closure 20, but the frangible line 28 can be molded as a solid line. The areas between the bridges 29 are then created by slagging, as described for example in U.S. Patent 4,595,547, the disclosure of which is incorporated herein by reference. Band 30 indicating tampering includes ring 32, which may be annular in shape. The band 30 indicating tampering also includes at least one tab 34, such as for example a plurality of tabs 34 arranged circumferentially around the ring 32. The tabs 34 are spaced slightly apart, as illustrated in Figure 1. Each tab 34 generally includes a pair of protruding elements 36 connected by a transverse element 38, the protruding elements 36 of each tab 34 being angularly inward toward each other. Each of the prominent elements 36 are connected to the ring 32 in a base 40 of the prominent element. Each tongue 34 is a generally trapezoidal element having a generally trapezoidal hole therethrough. The trapezoidal hole may be located at the base of the tongue 34 instead of for example the center of the tongue 34. The resulting structure comprises the two prominent elements 36 and transverse element 38. In an exemplary embodiment, each tongue 34 is relatively thin at its base 40 and gradually thickens moving toward the tip 42, as illustrated in Figures 5 and 6. The geometric shape of the tongue 34 creates a bi-stable configuration having equilibrium positions in both a downward orientation as an upward orientation. In particular, the band 30 indicating tampering can be molded with tabs 34 in the downward and inward orientation, for example to approximately 60 ° from the horizontal. This configuration is illustrated in Figures 1, 2 and 5. As indicated above, the molding of the tabs 34 and the downward orientation provides manufacturing advantages over the molding of tabs 34 in an upward orientation. After molding, the tongues 34 can be folded in an upward orientation. Because the cross member 38 is relatively thick compared to the base of each prominent element 36, it does not tend to compress or flex significantly during folding. Rather, the folding action urges the protruding elements 36 outwardly away from each other as the tongue 34 approaches the horizontal. At a point near the horizontal, the prominent elements 36 are at a maximum outward angle. Once beyond the horizontal, the continued upward movement tends to return the prominent elements 36 to their original inwardly directed angle. Thus, as the tongue 34 is moved upward first, the tendency of the prominent elements 36 to return to their original angle urges the tongue 34 toward the downward orientation. If the tab 34 were released before reaching the horizontal, it would return to the downward orientation. However, once the tongue 34 passes through a point approximately in the horizontal, then it will be pushed towards the upward orientation. When the tongue 34 is released after passing this point, it will move toward the stable upward orientation, for example about 60 ° above the horizontal. This position is illustrated in Figures 3, 4 and 6. With the tabs 34 in the upward orientation, the closure 20 can be applied to the container 10 and the tabs 34 can also be urged upwards to pass over the shoulder 16 of the container. . Once past the shoulder 16, the tabs 34 can return to the normal upward orientation and lock under the shoulder 16. In this position, the tabs 34 can be brought into contact with the neck 12, shoulder 16 or both. Alternatively, the tabs 34 can rest just below the shoulder 16 'without contacting the shoulder 16 or neck 12. When the closure 20 is removed, the tabs 34 will contact the shoulder 16 to prevent the band 30 from indicates tampering is removed from the container 10 with the remainder of the closure 20. The band 30 that indicates tampering will consequently be separated from the skirt 24 along the frangible line 28, providing indication of tampering. Figures 8 to 14 illustrate a closure 21 in accordance with an exemplary embodiment of the present invention, which includes a plurality of tongue extensions 34a arranged circumferentially on the tip 42 of each tongue 34. The tongue extensions 34a extend far away from the tip 42 along a plane defined by the prominent elements 36 and transverse element 38 of each tongue 34. In an exemplary embodiment, each tongue extension 34a is wedge-shaped or trapezoidal and extends from a central portion of the tongue. cross member 38. The tongue extensions 34a are configured to engage with a container profile to provide additional stability and prevent unfolding which results in a "separation" of the band 30 indicating tampering and loss of evidence of tampering. It will be appreciated that the size and shape of the tongue extension 34a may be configurable to suit the appropriate container profile and / or to provide the appropriate stability and function. For example, the tongue extension 34a can be configured to any length or width and can be formed into any suitable shape, including, for example, rectangular, square, trapezoidal, cuboid, wedge-shaped, pyramid-shaped. , in the shape of a curve, in the form of a bell, in the form of a tetragon, with multiple faces, etc. In addition, the edges of the tongue extension 34a may be smooth or non-smooth, in which for example, toothing, in forks, chipped, dotted, etc. are included. As illustrated, for example, in Figure 14, the tongue extensions 34a may have a thickness substantially less than the thickness of the tongues 34. Figure 14 illustrates a cross-sectional view of an exemplary closure 21 according to the present invention. invention coupled with a container 10. The tongue extensions 34a may be designed to fit a number of different profiles to provide evidence of tampering for a variety of different types of containers. In this regard, the closure 21 may not need to be redesigned to accommodate multiple profiles. In accordance with another exemplary embodiment of the present invention, the tongue extensions may be provided on only a few selected tabs. In this regard, some tabs may be provided with a tongue extension and some tabs may lack a tongue extension. For example, a tongue extension may be provided on one tongue and another not, such that an alternating sequence of tongues with a tongue and tab extension without tab extension may be performed. In accordance with another exemplary embodiment of the present invention, the tongue extensions of the tabs of a single closure may be non-uniform in size and shape. For example, some tongue extensions may be trapezoidal in shape and some tongue extensions may be bell-shaped. According to another exemplary embodiment of the present invention, each tongue may include a plurality of tongue extensions, the placement of which may differ in the tongue. For example, each tab can be provided with two tongue extensions placed on distal ends of the transverse element of the tongue or alternatively, the two tongue extensions can be provided on opposite edges of the transverse edge, such that they face each other. and they are separated only by the width of the transverse element. Figures 15 to 18 illustrate in side view exemplary tongue extension configurations in accordance with the present invention. It will be appreciated that many alternative tongue configurations may be provided.

The closures 20 and 21 and the container 10 can be formed from any suitable materials and can be constructed using any appropriate process. The closures 20 and 21 can be unitary elements (including the band 30 indicating tampering) and can be made of plastic. Exemplary plastics may include polypropylene and polyethylene. The closures 20 and 21 can be formed by compression molding or injection molding. The container 10 may also be a unitary element formed of either glass or plastic, in which are included, for example, polyethylene terephthalate ("PET"), polypropylene, and polyethylene. The container 10 can be formed using a blow molding process and in particular if PET is used, then the container 10 can be stretched blow molded. The tabs 34 can be folded using any appropriate process. However, the tongues 34 can be folded by punching the tongues 34 upwards. The device according to the present invention has been described with respect to several exemplary embodiments, however, it will be understood that there are many other variations of the embodiments described above which will be apparent to those experienced in the art, even where elements they have not been - explicitly designated as exemplary. For example, the closure 20 may include an annular sealing ring 50 to help seal the container contents 10 from contamination or deterioration. Similarly, the closure 20 may include a plurality of ridges on the outer surface of the skirt 24 to provide a frictional grip surface for the consumer. It will be understood that these and other modifications are within the teachings of the present invention which will be limited only by the claims appended hereto.
