ABSTRACT:
The present thermoformed containers are recloseable and resealable. This is accomplished primarily by providing a thermoformed container with a threaded neck and the use of a conventional type of closure on the threaded neck of the thermoformed container. The threads are on the neck and preferably also on an outwardly extending peripheral edge on the neck. This outwardly extending peripheral edge is created in thermoform molding. The neck preferably also is in the form of a two or more ply structure and in a further preferred embodiment the neck is reinforced by the closure. The closure in the embodiment of external threads on the neck has a reinforcing plug. In this embodiment the reinforcing plug fits into the neck adjacent the inner wall of the neck while the threads of the closure contact the exterior wall of the neck. In the embodiment of internal threads on the neck the closure can have a skirt which is in close contact with the exterior wall of the neck. This will likewise reinforce the neck. The neck can be of many shapes from cylindrical to approaching a rectangular shape.
