Definitions
- Disposable containers for packaging and storing edible goods are often provided with tamper resistant and tamper evident features to prevent unauthorized access to the interior of the container and to indicate to a consumer when the container has previously been opened. That the consumer still finds it desirable to have the tamper evident and resistant features in combination with a resealable container increases the complexity of the container, which may make it more difficult and time consuming to open.
- an embodiment of the disclosure relates to a container that comprises a tray comprising a bottom wall and a peripheral side wall extending upwardly from the bottom wall, which collectively define a compartment, and terminating in a tray rib to at least partially define an open top providing access to the compartment.
- the container further comprises a cover comprising a top wall that terminates in a cover rib having a peripheral cover lip, an interference element extending from the container, at least one tab provided in the container and associated with the interference element, and at least one line of weakness coupling the tab to the container.
- the tab is moveable between a first position where the line of weakness is not severed and a second position where the line of weakness is severed.
- the at least one tab and interference element are juxtaposed such that the interference element prevents the return of the tab to the first position after the tab is moved to the second position.
- An aspect of the present invention provides a container comprising: a tray comprising a bottom wall and a peripheral side wall extending upwardly from the bottom wall, which collectively define a compartment, and terminating in a tray rib to at least partially define an open top providing access to the compartment; a blocking wall extending from the tray rib and having an opening; a cover comprising a top wall terminating in a cover rib having a peripheral cover lip; a tab extending from the cover rib and through the opening in the blocking wall; an interference element provided on the tray beneath the tab; at least one line of weakness coupling the tab to the cover; wherein the tab is movable between a first position where the line of weakness is not severed and a second position where the line of weakness is severed, and the tab and interference element are juxtaposed such that the interference element prevents the return of the tab to the first position after the tab is moved to the second position.

- Figures 1 and 2 illustrate a container 10 comprising a cover 12 and a tray 14.
- suitable materials for the container 10 include oriented polystyrene, polypropylene and polyethylene terephthalate. All or a portion of the container 10 can be formed so as to be translucent, transparent, opaque or a combination thereof. While the container 10 is illustrated as having a generally circular shape, the container 10 can have any geometric shape, non-limiting examples of which include square, rectangular, oval, octagonal, and hexagonal.
- the cover 12 includes a top wall 16 defining a plane. References to above/below the plane are made with respect to the cover 12 in a closed position, as illustrated in Figure 1 . References to inward/outward are made with respect to central axis of the container 10.
- the cover 12 includes a top wall 16 terminating in a cover rib 18 that extends around the perimeter of the top wall 16.
- the cover rib 18 can include a cover rib inner wall 20 extending from the top wall 16 and connected with a peripheral cover lip 24 by a cover rib top wall 22.
- the cover rib 18 is illustrated as having a generally U-shaped cross-section, although it is within the scope of the invention for the cover rib 18 to have an alternative cross-sectional shape.
- the tray 14 includes a bottom wall 30 from which extends a peripheral side wall 32 which terminates in a tray rib 34 that at least partially defines an open top providing access to the interior compartment of the container defined by the bottom 30 and the peripheral side wall 32.
- the tray rib 34 includes a tray rib inner wall 36 extending from the peripheral side wall 32 and connected with a tray rib outer wall 40 by a tray rib top wall 38 such that the tray rib 34 has a generally U-shaped cross-section, although it is within the scope of the invention for the tray rib 34 to have a different cross-sectional shape.
- the tray rib 34 can also be provided with a blocking wall 50 that is either part of the tray rib 34 or a separate structure.
- the blocking wall 50 can be spaced from the tray rib outer wall 40 by a gap 52.
- the blocking wall 50 can optionally include a flange 54 which can define the exterior perimeter of the container 10 or the blocking wall 50 can include additional structural features, such as a downwardly depending skirt, or no additional structural features without deviating from the scope of the invention.
- the blocking wall 50 can be provided with at least one tab 60 that can form a portion of the blocking wall 50 (as illustrated) or be separated from the blocking wall 50.
- the tab 60 is configured so as to be at least partially separable from the container 10 along at least one line of weakness.
- the tab 60 is coupled with the blocking wall 50 along two lines of weakness 62a, 62b. While two lines of weakness 62a, 62b are illustrated, it will be understood that the tab 60 can be defined by a single line of weakness or more than two lines of weakness.
- the lines of weakness can be in the form of a score line or a series of perforations configured to allow the tab 60 to be separated from the blocking wall 50 along the lines of weakness 62a, 62b.
- the lines of weakness 62a, 62b can be formed from a series of alternating rounded crests and troughs of narrowed thickness or areas of removed material.
- the lines of weakness 62a, 62b can extend around a portion of the tab 60 such that the tab 60 is only partially removed from the blocking wall 50 and remains attached to the container 10 when the lines of weakness 62a, 62b are severed.
- the lines of weakness 62a, 62b can extend around the entire perimeter of the tab 60 such that the tab 60 is removed from the blocking wall 50 and the container 10 when the lines of weakness 62a, 62b are severed.
- the tab 60 can optionally include a projection 64 to facilitate grasping the tab 60 to separate the tab 60 from the blocking wall 50 along the lines of weakness 62a, 62b.
- the tab 60 further includes an interference element 70 extending from the tab 60 into the gap 52.
- the interference element 70 can extend partially into the gap 52, as illustrated, or span the entire distance of the gap 52.
- the tab 60 can be separated from the blocking wall 50 along the lines of weakness 62a, 62b such that the tab 60 can be moved into a second position to provide access to the peripheral cover lip 24 such that a consumer can grasp the peripheral cover lip 24 to remove the cover 12 from the tray 14.
- separation of the tab 60 along the lines of weakness 62a, 62b provides an indication that the container 10 has been opened and thus provides an indication that the container 10 may have been tampered with.
- providing an indication that the container 10 has been opened refers to indicating that the container 10 was in a condition in which the cover 12 could be removed from the tray 14 in the intended manner, regardless of whether the cover 12 was actually removed from the tray 14.
- the blocking wall 50 inhibits a consumer from opening the container 10 without destroying or damaging the blocking wall 50 and/or the peripheral cover lip 24 without using the tab 60 in the intended manner.
- the peripheral cover lip 24 extends into the gap 52 between the blocking wall 50 and tab 60 and the tray rib outer wall 40, thus inhibiting direct access to the peripheral cover lip 24.
- the interference element 70 extends from the tab 60 into the gap 52 such that the interference element 70 engages the peripheral cover lip 24 through an interference fit. As can best be seen in Figure 5 , the interference element 70 engages and deflects the peripheral cover lip 24.
- the tab 60 and/or interference element 70 can be provided with an angled face 72 to facilitate deflecting the peripheral cover lip 24 as the cover 12 is positioned on the tray 14 and moved into the closed position.
- the interference element 70 can be in the form of a vertical rib (as illustrated), a rounded protuberance, or have any other geometric cross-sectional shape. While the interference element 70 is illustrated as positioned in a central portion of the tab 60, it is within the scope of the invention for the interference element 70 to be positioned off-center with the respect to the tab 60. It is also within the scope of the invention for the tab 60 to include multiple interference elements 70.
- the interference element 70 is configured of a size and shape to extend into the gap 52 to such an extent as to engage the peripheral cover lip 24 through an interference fit and deflect the peripheral cover lip 24.
- the width of the gap 52, the extent to which peripheral cover lip 24 extends into the gap 52, and the extent to which the peripheral cover lip 24 is deflected by the interference element 70 can be configured to inhibit direct access to the peripheral cover lip 24 while still allowing the cover 12 to be seated on the tray 14 in an initial closed condition prior to a first opening of the container 10 and prior to separation of the tab 60 along the lines of weakness 62a, 62b.
- Figure 6 which is a partial cross-section through a portion of the container 10 that does not include the interference element 70, the peripheral cover lip 24 can have little to no engagement with the blocking wall 50 when the cover is in the closed condition.
- the cover rib 18 can have a generally U-shaped cross-section defined by the cover rib inner wall 20, top wall 22, and peripheral cover lip 24 that is configured to receive a correspondingly U-shaped tray rib 34 defined by the tray rib inner wall 36, top wall 38 and outer wall 40.
- the cover rib 18 can include a cover seal structure formed at least in part by the cover rib inner wall 20 and the tray rib 34 can include a tray seal structure formed at least in part by the tray rib inner wall 36 which engages the cover seal structure when the cover 12 is in the closed position to form a peripheral seal.
- the perimeter of the tray 14 as defined by the tray rib inner wall 36 can be slightly smaller than the perimeter of the cover 12 as defined by the cover rib inner wall 20 to provide an interference fit between the tray rib inner wall 36 and the cover rib inner wall 20 to form the peripheral seal when the cover 12 is in the closed position.
- the tray 14 can further include an inner tray flange 74 provided between the peripheral side wall 32 and the tray rib 34 to form a seat that engages a portion of the cover top wall 16 and the cover rib inner wall 20 through an interference fit to form a peripheral seal between the cover 12 and the tray 14.
- a peripheral seal a liquid-tight peripheral seal and a liquid-resistant peripheral seal.
- a consumer separates the tab 60 from the blocking wall 50 along the lines of weakness 62a, 62b, as illustrated in Figures 7 and 8 , to move the tab 60 from the first position to the second position to gain access to the peripheral cover lip 24.
- the tab 60 is separable from the blocking wall 50 along parallel lines of weakness 62a, 62b, but remains connected with the container 10 at a tray outer flange 80 adjacent the blocking wall 50 by a living hinge 82.
- the living hinge 82 can be formed by scoring or thinning the material forming the living hinge 82.
- the tab 60 can be pivoted about the living hinge 82 away from the blocking wall 50 to provide access to the peripheral cover lip 24. The consumer can then grasp the exposed portion of the peripheral cover lip 24 and remove the cover 12 from the open top of the tray 14.
- the dimensions of the tab 60 can be configured to provide sufficient space between first and second ends 90a, 90b of the blocking wall 50, formed when the lines of weakness 62a, 62b are severed, to allow a consumer to grasp enough of the peripheral cover lip 24 to overcome the peripheral seal between the cover 12 and tray 14 to remove the cover 12 from the tray 14.
- the living hinge 82 is described as being formed in the tray outer flange 80, the living hinge 82 can be formed in the blocking wall 50 or within the tray rib outer wall 40 in a similar manner, as long as the positioning of the living hinge 82 is configured to allow the tab 60 to be pivoted into the second position such that the consumer can grasp the peripheral cover lip 24 in order to remove the cover 12 from the tray 14.
- the living hinge 82 can be configured as a line of weakness similar to the lines of weakness 62a, 62b, such that the tab 60 can be separated from the container 10 to provide access to the peripheral cover lip 24.
- Movement of the tab 60 from the first position to the second position provides an indication that the container 10 has been opened and thus provides the container 10 with a tamper evident feature.
- the blocking wall 50 and the tab 60 inhibit a consumer from accessing the peripheral cover lip 24 to open the container 10 without destroying or damaging the blocking wall 50 and/or the peripheral cover lip 24.
- the blocking wall 50 and tab 60 provide the container 10 with a tamper resistant feature in that the container 10 cannot be opened except in a manner which provides evidence that the container 10 has been opened.
- the interference element 70 inhibits replacement of the tab 60 back into the first position.
- the interference element 70 is configured to extend into the gap 52 and deflect the peripheral cover lip 24 when the cover 12 is in the closed position.
- the peripheral cover lip 24 and interference element 70 are configured such that there is at least some deflection of the peripheral cover lip 24 by the interference element 70 when the interference element 70 is in the first position such that once the tab 60 is severed along the lines of weakness 62a, 62b and the tab 60 is moved into the second position, the extent to which the peripheral cover lip 24 extends across the gap 52 and the dimensions of the interference element 70 inhibit re-positioning of the tab 60 back into the first position.
- the peripheral cover lip 24 and the interference element 70 when the tab 60 is in the first position, are configured to extend across the gap 52 such that there is at least some deflection, either equal or unequal, of both the peripheral cover lip 24 and the interference element 70 and/or tab 60.
- the peripheral cover lip 24 and interference element 70 are configured to extend into the gap 52 to inhibit re-positioning of the tab 60 back into the first position severing the lines of weakness 62a, 62b to move the tab 60 to the second position.
- the interference element 70 inhibits replacement of the tab 60 back into the first position after the container has been opened and enhances the visual indication provided by the tab 60 that the container 10 has been opened.
- the container 10 is illustrated as having a single tab 60, it is within the scope of the invention for the container 10 to include multiple tabs 60 providing more than one location by which the consumer can gain access to the peripheral cover lip 24.
- Figures 9-10 illustrate another embodiment of the invention comprising a container 110, which is similar to the first container 10 except for the manner in which a tab 60 is formed. Therefore, elements in the container 110 similar to those of the container 10 will be numbered with the prefix 100.
- the tab 160 is similar to the tab 60 except that the tab 160 is configured to pivot laterally rather than downward when the lines of weakness 162a, 162b are severed. While Figures 9 and 10 illustrate two lines of weakness 162a, 162b, it is within the scope of the invention for the tab 160 to be defined by a single line of weakness or more than two lines of weakness.
- the tab 160 is connected at one end to the blocking wall 150 by a line of weakness 162b and connected to the blocking wall 150 at an opposite end by a living hinge 182.
- the tab 160 can further be defined by an additional line of weakness 162a connecting the tab 160 to the tray outer flange 180. In this manner, the tab 160 can be separated from the blocking wall 150 at one end and along a bottom edge and pivoted laterally about the living hinge 182 to provide access to the peripheral cover lip 124 to open the container 110 in the same manner as described above for the container 10.
- the tab 160 also includes the interference element 170 which inhibits the tab 160 from being re-positioned back into the first position after the lines of weakness 162a, 16b are severed.
- the interference element 170 can be positioned off-center with respect to the tab 160 such that the interference element 170 is adjacent to the living hinge 182. Positioning the interference element 170 adjacent the living hinge 182 limits the extent to which the tab 160 can be moved back towards the first position; the farther away from the living hinge 182 the interference element 170 is positioned, the further the tab 160 can be moved back towards the first position before being deflected by the peripheral cover lip 124.
- Figure 11 illustrates another embodiment of the invention comprising a container 210, which is similar to the first container 10 except for the manner in which the cover 212 is connected with the tray 214. Therefore, elements in the container 210 similar to those of the container 10 will be numbered with the prefix 200.
- a hinge 300 can be provided to connect the cover 212 and the tray 214.
- a cover flange 302 can extend from a portion of the cover rib 218 between first and second ends 304 in the blocking wall 250 and be connected with a tray flange 306 extending from a portion of the tray rib 234 by a hinge line 308 that forms a hinge axis about which the cover 212 and tray 214 relatively rotate to move the container 10 between the opened and closed positions.
- the container 210 can be opened in the same manner as described above with respect to the container 10 and the blocking wall 250 provides a tamper resistant feature while the tab 260 and interference element 270 provide tamper evident features in the same manner as described above with respect to the container 10.
- the hinge 300 can include a single hinge line 308, as illustrated, or multiple hinge lines. It is also within the scope of the invention for the hinge 300 to include at least one line of weakness such that the cover 212 can be separated from the tray 214 along the at least one line of weakness. It is also within the scope of the invention for the tab 260 to be provided on the hinge 300.
- Figures 12-14 illustrate another embodiment of the invention comprising a container 310, which is similar to the first container 10 except for features related to the tab 60. Therefore, elements in the container 310 similar to those of the container 10 will be numbered alike, but with the prefix 3.
- the tab 360 is similar to the tab 60 except that the tab 360 is located as an extension from the cover 312, rather than the tray 314, as in previous embodiments. Further, the tab 360 is configured to pivot upward rather than downward, pivoting about the living hinge 382, when the lines of weakness 362a, 362b are severed. In this exemplary embodiment, the interference element 370, which inhibits the tab 360 from being re-positioned back into the first position after the lines of weakness 362a, 362b are severed, is positioned such that it protrudes from the tray 314, rather than from the tab 360 itself. While the tab 360 is illustrated as having two lines of weakness 362a, 362b, it is within the scope of the invention for the tab 360 to be defined by a single line of weakness or more than two lines of weakness.
- Figure 12 illustrates a top view of the container 310, showing the tab 360 provided on the cover 312 in a first position.
- the lines of weakness 362a, 362b have not been severed and are intact.
- the interference element 370 protrudes upwardly from the tray 314, contacting the tab 360.
- the contact between the interference element 370 and the tab 360 results in some strain being put upon the lines of weakness 362a, 362b, the force is not sufficient to cause the lines of weakness 362a, 362b to sever without the action of a consumer.
- the tab 360 extends through an opening in the blocking wall 350.
- the blocking wall 350 is positioned adjacent to the peripheral cover lip 324 and also serves to block access to the peripheral cover lip 324.
- Figure 13 illustrates a front view of the container 310, showing the tab 360 provided on the cover 312 in a second position.
- the lines of weakness 362a, 362b are severed.
- the tab 360 when lifted by a consumer, can be separated along the lines of weakness 362a, 362b from the adjacent portions of the cover 312 and pivoted upwardly about the living hinge 382. Further lifting force applied by the consumer results in the cover 312 separating from the tray 314, with the tab 360 serving as the grasping point by which the consumer can begin to lift the cover 312 away from the tray 314.
- the tray 314 also includes the interference element 370 which inhibits the tab 360 from being re-positioned back into the first position after the lines of weakness 362a, 362b are severed.
- the interference element 370 can be positioned either centered or off-center with respect to the tab 360 such that the interference element 370 is adjacent to the living hinge 382. Positioning the interference element 370 adjacent the living hinge 382 limits the extent to which the tab 360 can be moved back towards the first position. The farther away from the living hinge 382 the interference element 370 is positioned, the further the tab 360 can be moved back towards the first position before being deflected by the interference element 370.
- Figure 14 illustrates a partial cross-section of the container 310, showing the tab 360 provided on the cover 312 in a second position after it has been torn along the line of weaknesses and moved from the first position (shown in dashed lines). From this view, the upward pivot, as indicated by the arrow 400, of the tab 360 about the living hinge 382 can be more clearly seen. Further, it is shown that the placement of the interference element 370 adjacent the living hinge 382 prevents the tab 360 from being moved back towards the first position. Therefore, once the tab 360 is moved from the first position to the second position as part of removing the cover, the replacement of the cover will result in the interference element 370 preventing the return of the tab 360 to the first position. With the tab 360 being in the second position, the tab indicates that the container has been opened.
- the examples described herein showing the location of the tab 60, 160, 260, 360 and the interference element 70, 170, 270, 370 are non-limiting. Any suitable combination of tab 60, 160, 260, 360 and interference element 70, 170, 270, 370 location is within the scope of the invention.

- the interference element need not be located on the tab and the tab can be located on either cover or tray.
- the interference element 70, 170, 270, 370 can be located at any suitable point either on the tab 60, 160, 260, 360 or not on the tab 60, 160, 260, 360.
- the shape of the container is not limiting.
- the container can be of any desired shape, such as circular or polygonal.
- the container can or cannot have corners.
- the tabs and interference element can or cannot be located at a corner. There may be one or more combinations of tabs/interference elements per container.
- the embodiments of the invention described herein provide a container 10, 110, 210, 310 which is tamper resistant and also provides evidence to a consumer when tampering or attempts at tampering have occurred.
- the blocking wall 50, 150, 250, 350 inhibits a consumer from opening the container 10, 110, 210, 310 without destroying or damaging the blocking wall 50, 150, 250, 350 and/or the peripheral cover lip 24, 124, 224, 324 without using the tab 60, 160, 260, 360 in the intended manner.
- the tab 60, 160, 260, 360 is configured to be movable with respect to the blocking wall 50, 150, 250, 350 to provide access to the peripheral cover lip 24, 124, 224, 324 to remove the cover 12, 112, 212, 312 from the tray 14, 114, 214, 314 while also providing a visual indication that the container 10, 110, 210, 310 has been opened.
- the interference element 70, 170, 270, 370 enhances the visual indication that the container 10, 110, 210, 310 has been opened by inhibiting replacement of the tab 60, 160, 260, 360 back into a position in which it appears that the container 10, 110, 210, 310 has not been opened.
- the tab 60, 160, 260, 360 is configured such that once the container 10, 110, 210, 310 has been opened and the cover 12, 112, 212, 312 has been removed, the cover 12, 112, 212, 312 can be replaced and re-sealed with the tray 14, 114, 214, 314 while still providing visual evidence to a consumer that the container 10, 110, 210, 310 has already been opened.
- the different features and structures of the various embodiments of the container 10, 110, 210, and 310 may be used in combination with each other as desired.

Figures 1 and 2 illustrate acontainer 10 comprising acover 12 and atray 14. Non-limiting examples of suitable materials for thecontainer 10 include oriented polystyrene, polypropylene and polyethylene terephthalate. All or a portion of thecontainer 10 can be formed so as to be translucent, transparent, opaque or a combination thereof. While thecontainer 10 is illustrated as having a generally circular shape, thecontainer 10 can have any geometric shape, non-limiting examples of which include square, rectangular, oval, octagonal, and hexagonal. - Referring now to
Figure 2 , thecover 12 includes atop wall 16 defining a plane. References to above/below the plane are made with respect to thecover 12 in a closed position, as illustrated inFigure 1 . References to inward/outward are made with respect to central axis of thecontainer 10. Thecover 12 includes atop wall 16 terminating in acover rib 18 that extends around the perimeter of thetop wall 16. Thecover rib 18 can include a cover ribinner wall 20 extending from thetop wall 16 and connected with aperipheral cover lip 24 by a cover ribtop wall 22. In the embodiment ofFigure 2 , thecover rib 18 is illustrated as having a generally U-shaped cross-section, although it is within the scope of the invention for thecover rib 18 to have an alternative cross-sectional shape. - As illustrated in
Figures 2 and3 , thetray 14 includes abottom wall 30 from which extends aperipheral side wall 32 which terminates in atray rib 34 that at least partially defines an open top providing access to the interior compartment of the container defined by the bottom 30 and theperipheral side wall 32. In the embodiment ofFigures 2 and3 , thetray rib 34 includes a tray ribinner wall 36 extending from theperipheral side wall 32 and connected with a tray ribouter wall 40 by a tray ribtop wall 38 such that thetray rib 34 has a generally U-shaped cross-section, although it is within the scope of the invention for thetray rib 34 to have a different cross-sectional shape. Thetray rib 34 can also be provided with a blockingwall 50 that is either part of thetray rib 34 or a separate structure. The blockingwall 50 can be spaced from the tray ribouter wall 40 by agap 52. The blockingwall 50 can optionally include aflange 54 which can define the exterior perimeter of thecontainer 10 or the blockingwall 50 can include additional structural features, such as a downwardly depending skirt, or no additional structural features without deviating from the scope of the invention. - The blocking
wall 50 can be provided with at least onetab 60 that can form a portion of the blocking wall 50 (as illustrated) or be separated from the blockingwall 50. Thetab 60 is configured so as to be at least partially separable from thecontainer 10 along at least one line of weakness. In the embodiment ofFigures 2 and3 , thetab 60 is coupled with the blockingwall 50 along two lines ofweakness weakness tab 60 can be defined by a single line of weakness or more than two lines of weakness. The lines of weakness can be in the form of a score line or a series of perforations configured to allow thetab 60 to be separated from the blockingwall 50 along the lines ofweakness weakness weakness tab 60 such that thetab 60 is only partially removed from the blockingwall 50 and remains attached to thecontainer 10 when the lines ofweakness weakness tab 60 such that thetab 60 is removed from the blockingwall 50 and thecontainer 10 when the lines ofweakness - Referring now to
Figures 3 and 4 , thetab 60 can optionally include aprojection 64 to facilitate grasping thetab 60 to separate thetab 60 from the blockingwall 50 along the lines ofweakness tab 60 further includes aninterference element 70 extending from thetab 60 into thegap 52. Theinterference element 70 can extend partially into thegap 52, as illustrated, or span the entire distance of thegap 52. As illustrated inFigure 4 , when thecover 12 is in the closed position on thetray 14, theperipheral cover lip 24 is received within thegap 52 and engages theinterference element 70 on thetab 60 when thetab 60 is in a first position corresponding to a position in which thetab 60 prevents direct access to theperipheral cover lip 24, which, in the embodiment ofFigure 4 , corresponds to a position in which thetab 60 has not been separated from the blockingwall 50 along the lines ofweakness cover 12 is in the closed position and thetab 60 is in the first position, the blockingwall 50 and thetab 60 inhibit access to theperipheral cover lip 24 and in this manner inhibit removal of thecover 12 from thetray 14 to open thecontainer 10. - The
tab 60 can be separated from the blockingwall 50 along the lines ofweakness tab 60 can be moved into a second position to provide access to theperipheral cover lip 24 such that a consumer can grasp theperipheral cover lip 24 to remove thecover 12 from thetray 14. In this manner, separation of thetab 60 along the lines ofweakness container 10 has been opened and thus provides an indication that thecontainer 10 may have been tampered with. As used herein, providing an indication that thecontainer 10 has been opened refers to indicating that thecontainer 10 was in a condition in which thecover 12 could be removed from thetray 14 in the intended manner, regardless of whether thecover 12 was actually removed from thetray 14. The blockingwall 50 inhibits a consumer from opening thecontainer 10 without destroying or damaging the blockingwall 50 and/or theperipheral cover lip 24 without using thetab 60 in the intended manner. - Referring now to
Figures 5 and 6 , when thecover 12 is in the closed position and thetab 60 is in the first position, theperipheral cover lip 24 extends into thegap 52 between the blockingwall 50 andtab 60 and the tray ribouter wall 40, thus inhibiting direct access to theperipheral cover lip 24. Theinterference element 70 extends from thetab 60 into thegap 52 such that theinterference element 70 engages theperipheral cover lip 24 through an interference fit. As can best be seen inFigure 5 , theinterference element 70 engages and deflects theperipheral cover lip 24. It is also within the scope of the invention for there to be some deflection of thetab 60 and/orinterference element 70 by theperipheral cover lip 24 depending on the extent to which theperipheral cover lip 24 andinterference element 70 extend into thegap 52 and the relative strength of theperipheral cover lip 24 and theinterference element 70/tab 60. Theinterference element 70 can be provided with anangled face 72 to facilitate deflecting theperipheral cover lip 24 as thecover 12 is positioned on thetray 14 and moved into the closed position. - The
interference element 70 can be in the form of a vertical rib (as illustrated), a rounded protuberance, or have any other geometric cross-sectional shape. While theinterference element 70 is illustrated as positioned in a central portion of thetab 60, it is within the scope of the invention for theinterference element 70 to be positioned off-center with the respect to thetab 60. It is also within the scope of the invention for thetab 60 to includemultiple interference elements 70. - The
interference element 70 is configured of a size and shape to extend into thegap 52 to such an extent as to engage theperipheral cover lip 24 through an interference fit and deflect theperipheral cover lip 24. The width of thegap 52, the extent to whichperipheral cover lip 24 extends into thegap 52, and the extent to which theperipheral cover lip 24 is deflected by theinterference element 70 can be configured to inhibit direct access to theperipheral cover lip 24 while still allowing thecover 12 to be seated on thetray 14 in an initial closed condition prior to a first opening of thecontainer 10 and prior to separation of thetab 60 along the lines ofweakness Figure 6 , which is a partial cross-section through a portion of thecontainer 10 that does not include theinterference element 70, theperipheral cover lip 24 can have little to no engagement with the blockingwall 50 when the cover is in the closed condition. - Still referring to
Figures 5 and 6 , thecover rib 18 can have a generally U-shaped cross-section defined by the cover ribinner wall 20,top wall 22, andperipheral cover lip 24 that is configured to receive a correspondinglyU-shaped tray rib 34 defined by the tray ribinner wall 36,top wall 38 andouter wall 40. Thecover rib 18 can include a cover seal structure formed at least in part by the cover ribinner wall 20 and thetray rib 34 can include a tray seal structure formed at least in part by the tray ribinner wall 36 which engages the cover seal structure when thecover 12 is in the closed position to form a peripheral seal. In the embodiment ofFigures 5 and 6 , the perimeter of thetray 14 as defined by the tray ribinner wall 36 can be slightly smaller than the perimeter of thecover 12 as defined by the cover ribinner wall 20 to provide an interference fit between the tray ribinner wall 36 and the cover ribinner wall 20 to form the peripheral seal when thecover 12 is in the closed position. Additionally, or alternatively, thetray 14 can further include aninner tray flange 74 provided between theperipheral side wall 32 and thetray rib 34 to form a seat that engages a portion of the covertop wall 16 and the cover ribinner wall 20 through an interference fit to form a peripheral seal between thecover 12 and thetray 14. Non-limiting examples of a peripheral seal a liquid-tight peripheral seal and a liquid-resistant peripheral seal. - To open the
container 10, a consumer separates thetab 60 from the blockingwall 50 along the lines ofweakness Figures 7 and 8 , to move thetab 60 from the first position to the second position to gain access to theperipheral cover lip 24. In the embodiment ofFigures 7 and 8 , thetab 60 is separable from the blockingwall 50 along parallel lines ofweakness container 10 at a trayouter flange 80 adjacent the blockingwall 50 by a livinghinge 82. The livinghinge 82 can be formed by scoring or thinning the material forming the livinghinge 82. In this manner, after the lines ofweakness tab 60 can be pivoted about the livinghinge 82 away from the blockingwall 50 to provide access to theperipheral cover lip 24. The consumer can then grasp the exposed portion of theperipheral cover lip 24 and remove thecover 12 from the open top of thetray 14. - The dimensions of the
tab 60, as defined by the spacing of the lines ofweakness second ends wall 50, formed when the lines ofweakness peripheral cover lip 24 to overcome the peripheral seal between thecover 12 andtray 14 to remove thecover 12 from thetray 14. In addition, while the livinghinge 82 is described as being formed in the trayouter flange 80, the livinghinge 82 can be formed in the blockingwall 50 or within the tray ribouter wall 40 in a similar manner, as long as the positioning of the livinghinge 82 is configured to allow thetab 60 to be pivoted into the second position such that the consumer can grasp theperipheral cover lip 24 in order to remove thecover 12 from thetray 14. Alternatively, the livinghinge 82 can be configured as a line of weakness similar to the lines ofweakness tab 60 can be separated from thecontainer 10 to provide access to theperipheral cover lip 24. - Movement of the
tab 60 from the first position to the second position provides an indication that thecontainer 10 has been opened and thus provides thecontainer 10 with a tamper evident feature. The blockingwall 50 and thetab 60 inhibit a consumer from accessing theperipheral cover lip 24 to open thecontainer 10 without destroying or damaging the blockingwall 50 and/or theperipheral cover lip 24. In this manner, the blockingwall 50 andtab 60 provide thecontainer 10 with a tamper resistant feature in that thecontainer 10 cannot be opened except in a manner which provides evidence that thecontainer 10 has been opened. - Once the
tab 60 is moved into the second position, as illustrated inFigures 7 and 8 , theinterference element 70 inhibits replacement of thetab 60 back into the first position. As illustrated inFigures 4 and5 , theinterference element 70 is configured to extend into thegap 52 and deflect theperipheral cover lip 24 when thecover 12 is in the closed position. Once thetab 60 is separated from the blockingwall 50 along the lines ofweakness tab 60 does not have sufficient strength to deflect theperipheral cover lip 24 and thus theperipheral cover lip 24 will deflect thetab 60, preventing thetab 60 from being replaced into the first position after the lines ofweakness peripheral cover lip 24 andinterference element 70 are configured such that there is at least some deflection of theperipheral cover lip 24 by theinterference element 70 when theinterference element 70 is in the first position such that once thetab 60 is severed along the lines ofweakness tab 60 is moved into the second position, the extent to which theperipheral cover lip 24 extends across thegap 52 and the dimensions of theinterference element 70 inhibit re-positioning of thetab 60 back into the first position. Thus, it is possible that theperipheral cover lip 24 and theinterference element 70, when thetab 60 is in the first position, are configured to extend across thegap 52 such that there is at least some deflection, either equal or unequal, of both theperipheral cover lip 24 and theinterference element 70 and/ortab 60. Regardless of whether or not there is deflection of both theperipheral cover lip 24 and theinterference element 70 and/ortab 60 when thetab 60 is in the first position, theperipheral cover lip 24 andinterference element 70 are configured to extend into thegap 52 to inhibit re-positioning of thetab 60 back into the first position severing the lines ofweakness tab 60 to the second position. - Without the
interference element 70, it may be possible for thetab 60 to be re-positioned between the first andsecond ends wall 50 such that thetab 60 appears to be in the first position. In this scenario, it may not be evident to a consumer that thetab 60 has already been moved such that thecover 12 could be removed. Theinterference element 70 inhibits replacement of thetab 60 back into the first position after the container has been opened and enhances the visual indication provided by thetab 60 that thecontainer 10 has been opened. - While the
container 10 is illustrated as having asingle tab 60, it is within the scope of the invention for thecontainer 10 to includemultiple tabs 60 providing more than one location by which the consumer can gain access to theperipheral cover lip 24. -
Figures 9-10 illustrate another embodiment of the invention comprising acontainer 110, which is similar to thefirst container 10 except for the manner in which atab 60 is formed. Therefore, elements in thecontainer 110 similar to those of thecontainer 10 will be numbered with the prefix 100. - The
tab 160 is similar to thetab 60 except that thetab 160 is configured to pivot laterally rather than downward when the lines ofweakness Figures 9 and 10 illustrate two lines ofweakness tab 160 to be defined by a single line of weakness or more than two lines of weakness. In thecontainer 110, thetab 160 is connected at one end to the blockingwall 150 by a line ofweakness 162b and connected to the blockingwall 150 at an opposite end by aliving hinge 182. Thetab 160 can further be defined by an additional line ofweakness 162a connecting thetab 160 to the trayouter flange 180. In this manner, thetab 160 can be separated from the blockingwall 150 at one end and along a bottom edge and pivoted laterally about theliving hinge 182 to provide access to theperipheral cover lip 124 to open thecontainer 110 in the same manner as described above for thecontainer 10. - The
tab 160 also includes theinterference element 170 which inhibits thetab 160 from being re-positioned back into the first position after the lines ofweakness 162a, 16b are severed. In the embodiment ofFigures 9 and 10 , theinterference element 170 can be positioned off-center with respect to thetab 160 such that theinterference element 170 is adjacent to theliving hinge 182. Positioning theinterference element 170 adjacent theliving hinge 182 limits the extent to which thetab 160 can be moved back towards the first position; the farther away from the livinghinge 182 theinterference element 170 is positioned, the further thetab 160 can be moved back towards the first position before being deflected by theperipheral cover lip 124. -
Figure 11 illustrates another embodiment of the invention comprising acontainer 210, which is similar to thefirst container 10 except for the manner in which thecover 212 is connected with thetray 214. Therefore, elements in thecontainer 210 similar to those of thecontainer 10 will be numbered with the prefix 200. - As illustrated in
Figure 11 , ahinge 300 can be provided to connect thecover 212 and thetray 214. Acover flange 302 can extend from a portion of thecover rib 218 between first and second ends 304 in the blockingwall 250 and be connected with atray flange 306 extending from a portion of thetray rib 234 by ahinge line 308 that forms a hinge axis about which thecover 212 andtray 214 relatively rotate to move thecontainer 10 between the opened and closed positions. Thecontainer 210 can be opened in the same manner as described above with respect to thecontainer 10 and the blockingwall 250 provides a tamper resistant feature while thetab 260 andinterference element 270 provide tamper evident features in the same manner as described above with respect to thecontainer 10. Thehinge 300 can include asingle hinge line 308, as illustrated, or multiple hinge lines. It is also within the scope of the invention for thehinge 300 to include at least one line of weakness such that thecover 212 can be separated from thetray 214 along the at least one line of weakness. It is also within the scope of the invention for thetab 260 to be provided on thehinge 300. -
Figures 12-14 illustrate another embodiment of the invention comprising acontainer 310, which is similar to thefirst container 10 except for features related to thetab 60. Therefore, elements in thecontainer 310 similar to those of thecontainer 10 will be numbered alike, but with the prefix 3. - The
tab 360 is similar to thetab 60 except that thetab 360 is located as an extension from thecover 312, rather than thetray 314, as in previous embodiments. Further, thetab 360 is configured to pivot upward rather than downward, pivoting about theliving hinge 382, when the lines ofweakness interference element 370, which inhibits thetab 360 from being re-positioned back into the first position after the lines ofweakness tray 314, rather than from thetab 360 itself. While thetab 360 is illustrated as having two lines ofweakness tab 360 to be defined by a single line of weakness or more than two lines of weakness. -
Figure 12 illustrates a top view of thecontainer 310, showing thetab 360 provided on thecover 312 in a first position. When thetab 360 is in the first position, the lines ofweakness interference element 370 protrudes upwardly from thetray 314, contacting thetab 360. Although the contact between theinterference element 370 and thetab 360 results in some strain being put upon the lines ofweakness weakness tab 360 extends through an opening in the blockingwall 350. The blockingwall 350 is positioned adjacent to theperipheral cover lip 324 and also serves to block access to theperipheral cover lip 324. -
Figure 13 illustrates a front view of thecontainer 310, showing thetab 360 provided on thecover 312 in a second position. When thetab 360 is in the second position, the lines ofweakness tab 360, when lifted by a consumer, can be separated along the lines ofweakness cover 312 and pivoted upwardly about theliving hinge 382. Further lifting force applied by the consumer results in thecover 312 separating from thetray 314, with thetab 360 serving as the grasping point by which the consumer can begin to lift thecover 312 away from thetray 314. - The
tray 314 also includes theinterference element 370 which inhibits thetab 360 from being re-positioned back into the first position after the lines ofweakness Figure 13 , theinterference element 370 can be positioned either centered or off-center with respect to thetab 360 such that theinterference element 370 is adjacent to theliving hinge 382. Positioning theinterference element 370 adjacent theliving hinge 382 limits the extent to which thetab 360 can be moved back towards the first position. The farther away from the livinghinge 382 theinterference element 370 is positioned, the further thetab 360 can be moved back towards the first position before being deflected by theinterference element 370. -
Figure 14 illustrates a partial cross-section of thecontainer 310, showing thetab 360 provided on thecover 312 in a second position after it has been torn along the line of weaknesses and moved from the first position (shown in dashed lines). From this view, the upward pivot, as indicated by thearrow 400, of thetab 360 about theliving hinge 382 can be more clearly seen. Further, it is shown that the placement of theinterference element 370 adjacent theliving hinge 382 prevents thetab 360 from being moved back towards the first position. Therefore, once thetab 360 is moved from the first position to the second position as part of removing the cover, the replacement of the cover will result in theinterference element 370 preventing the return of thetab 360 to the first position. With thetab 360 being in the second position, the tab indicates that the container has been opened. - It will be understood that the examples described herein showing the location of the
