Abstract
A container and tamper evident closure comprising a container having a body portion, shoulder and a cylindrical dispensing unit extending upward from the shoulder. The closure is comprised of a closure aperture with a skirt depending from the area of the closure aperture. The cylindrical dispensing unit has a rotation limiting mechanism. The closure attaches to the cylindrical dispensing unit or to the shoulder and has one or more weakened areas on the skirt. Upon the twisting of the closure to remove it from the container the weakened areas are stressed and show distortion or are severed. This is clear evidence of tampering.
Description
- This invention relates to a container with a tamper evident closure. More particularly this invention relates to a closure where upon an unauthorized twisting to remove the closure portions of the closure will be distorted and/or ruptured.
- There are many technologies for making closures for containers tamper evident. These include shrink bands of plastic, a shrink sleeve over a part or all of a container and closure. In addition there are bands which are bridged to the closure where the bridged are broken upon an opening of the container. In each of these a tampering is evidenced by a lack of a shrink band or sleeve or a closure with a severed band. There are yet other tamper evident structures for a closure. However many require an added feature as discussed above where shrink bands or sleeves or a bridged band is required.
- The present invention solves the problem of having a less costly tamper evident closure for a container. No added item is required. The closure side surfaces will have one or more weakened areas. Upon an unauthorized attempted removal of the closure the one or more weakened areas will have become distorted and/or ruptured. This will be a positive indication of an unauthorized attempt to remove the closure and open the container. This product then is not available for purchase and is removed from the shelf.
- This tamper evident container and closure does not require any added item such as shrink bands or sleeves or bridged bands. The closure is one molded piece as in the container. Neither has an added item. The tamper evidency is accomplished solely by a restriction of rotation of the closure and weakened areas that distort and/or rupture upon a torquing of the closure during an attempt to remove the closure.
- The invention is directed to a container with a tamper evident closure which is comprised of a container having a body portion with a shoulder on one end of the body portion. Extending from the shoulder is a cylindrical dispensing unit. There is at least one anti-rotation means on an exterior surface of the cylindrical dispensing unit. The closure has a closure channel which when applied to the container is in alignment with the cylindrical dispensing unit of the container. A peripheral skirt extends down from an area surrounding the closure channel, this peripheral skirt having at least one weakened area. The closure also has a closure anti-rotation means which interacts with the anti-rotation means on the cylindrical dispensing unit. The cylindrical dispensing unit anti-rotation means preferably is a cam which interfits with at least one closure projection extending from the closure adjacent the closure channel. In a further preferred embodiment this projection has a ledge at a lower end which interacts with a flange on the cylindrical dispensing unit to attach the closure to the container.
- Upon an unauthorized attempt to remove the closure the cylindrical dispensing unit anti-rotation means prevents any rotation of the closure by keeping the at least one closure projection from rotating on the cylindrical dispensing unit. Such an attempt at rotation causes stress on the closure distorting and/or rupturing the at least one weakened area providing visual indication of an unauthorized tampering.

-
FIG. 1 shows thebody portion 12 of container andclosure 10 withright side surface 18 andfront surface 16. Closure 14 is attached tobody portion 12. The closure is comprised of a skirt 15 (seeFIG. 3 ) having aright sidewall 22 andfront wall 24.Lid 20 fully closes a dispensing opening of the closure.Ledge 26 provides a grip for theopening lid 20. Weakenedareas 76 on the inner surface offront wall 24 are shown in dashed lines. These are shown in more detail inFIG. 4 . -
FIG. 2 shows the container with the lid open. Theclosure 14 hastop surface 40 withchannel 43 defined byridge 42. Within thechannel 43 isanti-refill beam 44 which makes re-filling for reuse difficult. Thelid 20 is attached to thetop surface 40 byhinge 36. The lid has plug 32 for sealingaperture 43 and aforce transfer ring 30. The force transfer ring transfers forces on the exterior of lid directly to thetop surface 40 rather than from the lid edges to the top surface. -
FIG. 3 shows the closure in the same detail asFIG. 2 . However this view shows the upper part of the container in more detail. Thecontainer body 12 has ashoulder 48 which has aledge 50 formed byvertical surface 52. This ledge accepts the lower edge of the closure. The containershoulder top surface 54 supportscylindrical dispensing unit 58 and has aflange 62 for attachment of theclosure 14. Dispensingunit cam 56 is a part of the closure anti-rotation mechanism. Any equivalent projection can be used in place ofcam 56. This cam, along with a similar cam on the other side of the cylindrical dispensing unit, will prevent the rotation of the closure on the container body by cooperation with cam projections on the closure. Interference by the cams on the containercylindrical dispensing unit 58 and cam projections on theclosure 14 will prevent the rotation of theclosure 14 on thecontainer body portion 12. -
FIG. 4 is a plan view of the underside of theclosure 14. This view shows the outer surface oflid 20 and the inner surface ofskirt 15 of the closure. Theclosure 14 has aninner surface 70 of the cylindrical dispensing unit withaperture 43 defined byridge 42. Also shown isanti-refill bean 44. Projecting down frominner surface 70 areclosure cam projections 74. Theclosure cam projections 74 have two functions. The first is to provide an interference with cylindricaldispensing unit cams 56 and thus prevent rotation of theclosure 14 oncontainer body 12. The second is to haveledge 78 on theclosure cam projections 74 fit underflange 62 intospace 64 of thecylindrical dispensing unit 58 and prevented from rotation on the dispensing unit. Also shown in this view are weakenedareas 76 on the front 24 and rear 23 surfaces of the closure. These weakened areas are areas of a decreased thickness of the skirt walls. This can be a decrease of up to fifty percent or more. These weakened surfaces 76 will be distorted and/or ruptured upon a forced removal of theclosure 14 from thecontainer body 12. This distortion and/or rupture is evidence that the container has been subject to tampering. -
FIG. 5 is a cross-sectional view ofFIG. 4 along line 5-5. Shown is more detail is the structure ofclosure cam projections 74. These have anupper end 80 attached to the closure and alower locking ledge 78 for fitting underflange 62 and into spare 64 to secure theclosure 14 to thecontainer body 12. Also shown are weakenedareas 76 which are distorted or ruptured upon an attempt to remove the closure. -
FIG. 6 is a perspective view of the container alone. This view also shows container leftside 11. Also shown are the twocams 56 on thecylindrical dispensing unit 58. All of the other parts of the container have been described above. - The container is blow molded from essentially any thermoplastic. Useful thermoplastics are polyethylenes, polypropylenes, vinyl chlorides and polyethylene terephthalates. The closure will be injection molded and can be essentially any thermoplastic. Useful thermoplastics include those used for the container.
