Benefits of technology

[0013]In addition to having a complementary rim with multi-segment structure, the base comprises a floor and a sidewall, the sidewall extending between the floor and the rim. The base rim structure contains an undercut formation that is adapted to engage the perimeter flange of the lid. The method by which the lid is retained by the undercut formation of the base rim provides defense against access to the sealed container contents via prying of the lid from the base.

Problems solved by technology

A problem with this method of tamper evidence is that the container requires articles apart from the container itself to effect the tamper evidence.
Still another problem with the prior art tamper evident food container arises from the sealing arrangement of the container rims.

Embodiment Construction

[0031]A preferred embodiment container 10 of the present invention in the sealed arrangement is shown in FIGS. 1 and 4. As shown by these figures container 10 is composed of lid 11 and base 25. Lid 11 includes upper portion 12, descending surface 13 and multi-segment rim 14. Lid 11 is manufactured from a conventional plastic material and is clear. Upper portion 12 is preferably flat, but can be contoured and ribbed in accordance with the prior art to enhance such factors as container volume, strength, nesting of multiple lids, stackability of sealed containers and see-through visibility. In the preferred embodiment lid upper portion 12 includes top plateau 15 and intermediate terrace 16. First lid transition segment 17 extends between plateau 15 and terrace 16. Terrace 16 continues on to form second vertical transition segment 18. Vertical transitional section 18 provides structural rigidity to lid 11 and extends from terrace 16 to descending surface 13, which in the preferred embod...

Abstract

A plastic food container includes a lid adapted for sealing arrangement with a base. The rim of the base has an undercut formation adapted to receive the perimeter flange and flange tab of the lid when the lid and base are in the sealed arrangement. The flange tab includes an undercut release mechanism that allows a user to grasp a portion of the flange tab and initially open a sealed container via the extraction of the flange tab from the undercut formation by application of pulling force to the undercut release mechanism. The flange tab includes tamper evident means that provides visible indication that the undercut release mechanism has been utilized to initially open the sealed container.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]Not Applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.SEQUENCE LISTING, TABLE OR COMPUTER PROGRAM ON COMPACT DISC[0003]Not applicable.FIELD OF INVENTION[0004]This invention relates generally to plastic food containers. The invention is more specifically related to resealable plastic food containers having tamper evident sealing mechanisms.BACKGROUND OF THE INVENTION[0005]It is known to use plastic containers in the food preparation and restaurant industry to package prepared foods. The typical food container of the prior art consists of a solid color (typically black) base and a clear lid. The clear lid of the prior art plastic food container allows visible inspection of the container contents. The lid and base of the prior art plastic food container may be separate articles or may be hingedly attached to each other.[0006]In order to maintain the quality of food contents and prevent tampering wi...
