Abstract

A tamper-evident container includes a base and a lid with a closure portion includes a lip flange and a base flange. When the lid is secured to and closed over the base, the lid flange and the base flange rest adjacent to one another. The base flange includes perforations running along the length of the closure portion to divide the base flange into an outer region and an inner region. The lid flange is secured to the outer region of the base flange. When the lid is separated from the base, the lid flange tears away the outer region of the base flange with the assistance of the perforations on the base flange. When the lid is fully separated from the base, the lid flange carries the outer region of the base to avoid a separate member that needs to be thrown away.

Dependent claims

A tamper-evident container, comprising:

a base having a bottom with at least one upstanding side wall defining a cavity therein, the base further includes a top peripheral edge defining a top open end and a base flange extending outwardly from at least a portion of the top peripheral edge, wherein the base flange comprises an inner portion and an outer portion being removably attached to the inner portion;
a lid, having a peripheral edge, the lid being hingedly connected to the base and configured to substantially enclose the top open end when attached to the top peripheral edge, wherein the peripheral edge is fixed to the outer portion of the base flange;
and
a hinge member hingedly connecting the lid to the base;
wherein separation of the lid from the base pulls the outer portion of the base flange away from the inner portion of the base flange,
wherein the outer portion of the base flange is left fixed to the lid flange after full separation of the lid from the base, thereby enabling access to the cavity of the base.
