US 5,238,134 A · Limited-reuse tamper-evident container

Abstract

A tamper-evident container is disclosed that can be reused a limited number of times with the tamper-evident feature for secure storage or transport of material. The container is made up of a base and a lid. The base has a hollow interior for holding material and an open top. The base also has a number of platform-like holders, each with a hole, that project perpendicular to and inwardly from the interior walls of the base. The holders are used in attaching the lid to the base. The lid is the same shape as the base (i.e., multisided, hexagonal, or circular). The lid contains frangible elements which outnumber the holders in the base. Each frangible element is made up of a shaft tipped with a cone. Frangibility of the element is achieved by dividing it into quadrants and scoring the base. Each element extends downward from the interior-top of the lid. A subset of the frangible elements align with the holders in the base. The container is closed when a subset of frangible elements engage with the holders. The lid and the base each have a built-in handle. The container is opened by pulling on the handles to separate the lid from the base. The frangible elements are broken when the container is opened. Tampering is defined as unauthorized opening. The container can be reused with this tamper-evident feature by rotating the lid with respect to the base so that another subset of unbroken frangible-elements align with the holders so that the container upon engagement of the new subset.

Dependent claims

A limited-reuse tamper-evident container assembly or indicating whether said assembly has been opened a limited number of times comprising:

(a) a base for holding materials contained therein including a surface, side walls extending orthogonally from said surface, an open top opposite said surface, and at least one platform-like structure extending inwardly from said side walls, said at least one platform-like structure being situated between said surface and said open top, each of said at least one platform-like structure includes a hole;
and
(b) a removable lid applicable to said base for closing said container assembly including a surface, side walls extending orthogonally from said surface, an open bottom opposite said surface that fits snugly over said side walls of said base, and a plurality of frangible elements extending from said surface toward said hole in said at least one platform-like structure of said base wherein one of said frangible elements engages with each said at least one platform-like structure to secure said lid to said base and provide evidence of removal of said lid from said base which results in the destruction of said engaged frangible element, unused and unbroken frangible elements provide a limited number of tamper-evident reuses of said container assembly by allowing the lid to be repositioned with respect to said base in order to engage another of said unbroken frangible elements, each of said frangible elements includes a quartered stem integrally molded with said surface of said lid and a quartered cone at a free end of said stem, said stem includes a weakened point of reduced cross section disposed at an end of said stem opposite said free end thereof.
