Tamper evident container

1. A container having tamper evident and tamper resistant features comprising:

a tray comprising a bottom wall and a peripheral side wall extending upwardly from the bottom wall and terminating in an outwardly extending tray flange and a rib projecting upwardly from at least a portion of the tray flange to at least partially define an open top, the rib comprising a tray seal structure;

a cover comprising a top wall and terminating in an outwardly extending cover flange with a skirt projecting upwardly from the cover flange and terminating in a peripheral cover lip, the skirt comprising a cover seal structure, and a blocking wall extending from the top wall to define a gap between the blocking wall and the skirt; and

a peripheral seal formed by the tray seal structure and the cover seal structure when the cover closes the open top of the tray;

wherein when the cover is mounted to the tray to close the open top of the tray, a portion of the skirt lies on top of and terminates on the rib leaving the peripheral cover lip accessible, and wherein a length of the portion of the skirt that lies on top of the rib is less than 0.125 inches and the gap has a width less than 0.350 inches, wherein an amount of the skirt that is pinchable is insufficient to apply the force required to overcome the peripheral seal to separate the cover from the tray.

2. The container of claim 1 wherein the blocking wall is spaced from the cover skirt by 0.177 inches or less.

3. The container of claim 1 wherein a length of the at least a portion of the skirt lying on top of the rib is approximately 0.060 inches or less.

4. The container of claim 1 , further comprising a hinge defining a hinge axis and connecting the tray and the cover for relative rotation about the hinge axis between a closed position and an opened position.

5. The container of claim 4 , further comprising a first tab provided on one of the cover or the tray and a second tab provided on the other of the cover or the tray, wherein the first and second tabs are adjacent to each other.

6. The container of claim 5 wherein the first and second tabs at least partially overlap vertically.

7. The container of claim 5 wherein the first and second tabs are laterally offset from the hinge.

8. The container of claim 5 wherein the first and second tabs are vertically offset from one another.

9. The container of claim 4 wherein the hinge comprises at least one line of weakness configured to tear when the container is opened.

10. The container of claim 4 wherein the hinge comprises first and second lines of weakness with at least one of the first or second lines of weakness configured to tear when the container is opened.

11. The container of claim 10 wherein the at least one of the first or second lines of weakness configured to tear when the container is opened is linear or non-linear.

12. The container of claim 1 further comprising at least one bar lock securing together the cover and the tray, and wherein the amount of the skirt that is pinchable is insufficient to apply the force required to overcome the at least one bar lock to separate the cover from the tray.

13. The container of claim 1 wherein the amount of the skirt that is pinchable corresponds to an amount that an individual can grasp between a thumb and an index finger.

14. The container of claim 1 wherein the skirt comprises an outer terminal edge that lies on top of the rib and wherein an angle of at least a portion of the skirt presses the outer terminal edge against the top of the rib when the cover is mounted to the tray to close the open top of the tray.
