SANITARY CONTAINER AND LID CONSTRUCTION
First Claim
1. A combined container and closure assembly, said container comprising a substantially thin-walled plastic container having a substantially annular curled rim portion the upper surface of which is a convex curve, said closure comprising a flat rectangular sheet positioned on said rim portion of said container substantially in a flat plane tangentially directly engaging the uppermost extremity of said upper surface, said closure having a width and length greater than the diameter of the circle defined by the tangential engagement of said closure with said upper surface, and a coating film substantially completely covering said rim portion only from a first ring immediately outwardly of said circle defined by said tangential engagement thereof by said closure to the outer lowermost extremity thereof, said coating film being secured to said closure member only on a ring coinsiding with said first ring and having greater adherence thereto than the adherence of said coating film to said rim portion, whereby a peeling removal of said closure from said container will remove said coating film with said closure.

Abstract
A sanitary container and lid construction with the open end of the container presenting a peripheral drinking or pouring lip and initially covered by a coating layer or film to which the container lid or film is suitably attached. It is alternatively contemplated that the lid may be attached both to the rim or lip and the coating. The coating and lid preserves the initial sanitary condition of the lip and the interior of the container, and the coating and lid are of such that the coating and lid will be peeled away from the lip with a reverse drawing of one edge of the lid across the top of the container to expose the contents of the container and to leave a sanitary lip for drinking or pouring purpose.
