초록 ▼

A tear-back drink-through lid for a drinking cup sealingly engages the drinking cup at an annular mounting portion with a downwardly extending annular skirt. The tear-back section extends from the inner skirt to a hinge and has an outwardly extending raised protrusion. When the tear-back section is torn away from the lid and pivoted about the hinge, the raised protrusion is frictionally engaged by the end walls of the recess and retained within the recess. The recess further includes a straw slot formed therein defined by two sloping converging sidewalls extending from the upper surface the lid at different angles to form a frangible juncture at the deepest portion of the recess.

대표청구항 ▼

We claim: 1. A disposable lid for a drinking cup comprising; an annular mounting portion for scalingly engaging a brim of the drinking cup; a substantially planar medial portion for covering an opening of the drinking cup; a recess having at least two side walls, said side walls extending from said planar medial portion and converging toward one another forming an apex; wherein said at least two side walls extend towards said apex at different angles with respect to a vertical plane of said recess including said apex; wherein said at least two side walls converge together at a frangible portion formed in a deepest portion of the recess, and wherein a thickness of the lid material at the frangible portion is thinner than the lid material in other portions of the lid thereby allowing the frangible portion to be ruptured by a force exerted by an end of a straw as it is inserted into the frangible portion. 2. The lid as defined in claim 1, wherein one of the side walls of said recess slopes at an angle in the range of 30째 to 60째 with respect to said vertical plane and the other of said side walls of said recess slopes at an angle in the range of 0째 to 10째 with respect to said vertical plane. 3. The lid as defined in claim 1, wherein one of the side walls of said recess slopes at an angle in the range of 45째 to 50째 with respect to said vertical plane and the other of said side wall of said side walls of said recess slopes at an angle in the range of 2째 to 5째 with respect to said vertical plane. 4. The lid as defined in claim 1, wherein one of the side walls of said recess slopes at an angle of 47째 with respect to said vertical plane and the other of said side walls of said recess slopes at an angle of 4째 with respect to said vertical plane. 5. The lid as defined in claim 1, wherein said recess further includes end walls extending between said side walls, and said end walls of said recess slope toward one another in a direction from said medial portion of the lid to said apex. 6. The lid as defined in claim 5, wherein said end walls slope toward one another at an angle in the range of 0째 to 10째 with respect to a second vertical plane perpendicular to said vertical plane. 7. The lid as defined in claim 5, wherein said end walls slope toward one another at an angle in the range of 2째 to 5째 with respect to a second vertical plane perpendicular to said vertical plane. 8. The lid as defined in claim 5, wherein said end walls slope toward one another at an angle of 4째 with respect to a second vertical plane perpendicular to said vertical plane.
