Enhanced tamper-evident container

摘要

A tamper-evident container has a lid (14) that can be opened only by lifting and pulling a tab (18). Pulling of the tab breaks a breakable joint (41, 43, 70, FIG. 4) that connects the tab (18) to a hold-down (24) that is fixed to the lid, so when the tab is released from the hold-down the tab springs up (FIG. 2) to an upward incline J to indicate that the container was opened.

主权项

1. A container for providing evidence of tampering, comprising:
a base; a lid having a two component pull-tab assembly, said lid engageable with the base, said lid comprising an outer lid rim and a inner removable lid cover, said inner removable lid cover having a lockdown recess, and said two component pull-tab assembly connected to the outer lid rim; wherein said two component pull-tab assembly comprises an outer frangible pull-tab, and an inner hold-down tab; wherein the outer frangible pull-tab and the inner hold-down tab define a channel between the outer frangible pull-tab and the inner hold-down tab; wherein there is at least one frangible connection joint in the channel connecting the outer frangible pull-tab and the inner hold-down tab; wherein the outer frangible pull-tab further comprises a first rear connecting joint that defines a first terminus of the channel, and a second rear connecting joint that defines a second terminus of the channel; wherein the first rear connecting joint and the second rear connecting joint have a foldable hinge, and wherein the first rear connecting joint and the second rear connecting joint are connected to the outer lid rim; and, wherein the foldable hinge comprises at least one bend, wherein the bend positions the outer frangible pull-tab into a steep upward incline when the frangible connection joint in the channel is broken, whereby the upwardly inclined outer frangible pull-tab provides a user with visual evidence of tampering.
