  Containers with discontinuous sealUSPTO Application #: 20080073368Title: Containers with discontinuous seal Abstract: Polymeric containers that have a container body and a removable and replaceable lid configured for sealing engagement with the body. The sealing arrangement between the container body and the lids includes a discontinuity feature that provides a passage for fluid from the exterior of the container to the sealing arrangement, which reduces the forces needed to open (e.g., unseal) or vent the container. The containers are often thermoformed, and might be considered “disposable” containers.

CROSS-REFERENCE TO RELATED APPLICATION [0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/823,341, filed Aug. 23, 2006, entitled "Containers with Discontinuous Seal, and Methods", which application is hereby incorporated by reference in its entirety. TECHNICAL FIELD [0002]This disclosure generally relates to polymeric packages or containers, and, in particular, to rigid polymeric containers having a container body and a removable lid, the lid and container configured to cooperatively close but with at least one discontinuous seal region present around the engageable body and lid. BACKGROUND [0003]Enhancing the sealing and opening capabilities of rigid containers, both disposable containers intended for one-time use and those intended for repeated use, is an area of ongoing development. SUMMARY OF THE DISCLOSURE [0004]The present disclosure is directed to generally rigid, polymeric containers that have a body and a removable and replaceable lid configured for engagement with the body. The containers are often thermoformed, and are typically considered "disposable" containers, in that they may be discarded after one use, or a limited number of uses, generally dictated by the strength, integrity, and/or quality of the polymeric materials used to form the container. [0005]The present disclosure is directed to a container design that reduces the forces needed to open (e.g., unseal) or vent a container. The designs of this disclosure facilitate the removal of the lid from the container body. The configuration, in some embodiments, also functions as a drain passage, for example, to assist in water drainage from the container body after washing. [0006]The container includes a discontinuity feature in the sealing arrangement between the container body and the lid that provides a passage for fluid from the exterior of the container to the sealing arrangement. In some embodiments, the discontinuity feature, instead, provides a passage for fluid from the interior of the container to the sealing arrangement. In either case, the discontinuity features facilitates separating the container body and the lid when opening the container. The discontinuity feature may be present in one or both of the container body or the lid. In some embodiments, multiple discontinuity features are present in the container, and, in some of these embodiments, the features are distributed in more than one area of the container. In addition to the sealing arrangement including its discontinuity feature, the container can also include, for example along a different surface of the sealing arrangement, a leak-proof seal.
