Container with improved tamper evident structure

摘要

A container includes a basket and lid. The basket and lid each have a lip along at least a portion of a periphery and a tear strip connected along at least a portion of the lip. An outer edge of the lip includes notches and an inner edge of the tear strip complements the outer edge of the lip. The tear strip is connected to the lip by links arranged at notches of the outer edge of the lip. The basket tear strip is bonded to the lid tear strip to resist separation of the lid from the basket. The bonded basket tear strip and lid tear strip are detachable from the basket lip and the lid lip urged away from the basket and the lid, exposing the outer edge of the basket lip and the outer edge of the lid lip.

主权项

1. A container, comprising:
a basket connected with a basket tear strip by basket links along a basket lip having an outer edge comprising an undulating series of rounded protrusions and rounded indentations, the basket links extending from alternating indentations of the outer edge of the basket lip such that no basket links extend from protrusions; and a lid mated with the basket and connected with a lid tear strip by lid links along a lid lip having an outer edge comprising an undulating series of rounded protrusions and rounded indentations, the lid links extending from alternating indentations of the outer edge of the lid lip such that no lid links extend from protrusions; wherein the lid tear strip is bonded to the basket tear strip to form a seal; wherein when the lid tear strip is bonded to the basket tear strip, the basket links and lid links are staggered from each other by an indentation so that an applied force necessary to separate the basket tear strip from the basket and the lid tear strip from the lid is determined by an applied force necessary to separate one of a basket link from the basket tear surface and a lid link from the lid tear surface; and wherein when a force applied to the seal separates the basket tear strip from the basket and the lid tear strip from the lid so that the lid is separable from the basket, chaff comprising portions of the basket and lid links are recessed within associated rounded indentations of the basket lip and the lid lip so that no chaff extends from the outer edges of the lid lip and the basket lip beyond adjacent rounded protrusions.
