Abstract

A paper cup having an aperture in the cap positioned to enable a user to drink from the cup through the aperture. Leakage through a gap between cap and cup, normally found in caps of the prior art formed by a step in the rim of the cup at the meeting location of the cup rim and seam of the cup, is prevented by any one of sevearal embodiments of the invention.

Claims14

Dependent claims

A beverage dispenser for enabling a user to drink from said dispenser which comprises:

a cup, being a sheet of paper having a thickness', and being substantially rectangular, and having a first pair of opposing edges and a second pair of opposing edges;
said sheet rolled to where one edge of said first pair of edges overlaps and adheres to another edge of said first pair of edges;
whereby a truncated cone being side of a cup is formed having a seam of double said thickness formed by said overlapping first pair of edges;
a bottom panel adhered to one edge of said second pair of edges whereby a bottom of said cone is formed enabling said cup to hold said beverage;
another edge of said second pair of edges operably rolled to form a rim extending around said cone along said another edge of said second pair of edges whereby said cup, being a truncated cone with a closed bottom and open top with a rim, is formed;
a cap having a drinking aperture and arranged to snap onto said rim enabling a user to drink beverage from said cone through said aperture from said cup;
means for preventing spillage from said beverage dispenser resulting from one of:
(i) formation of a gap between said cap and said rim at a location where said rim meets said seam, said gap, without said means, resulting from a step in said rim formed by said double thickness of said seam in combination with a single thickness of said sheet remote from said location;
said gap resulting in leakage of beverage through said gap when said aperture in said cap is proximal to said gap when said user attempts to drink from said cup through said aperture.
(ii) said aperture in said cap, without said means for preventing, being proximal to a gap between said cap and said rim at a location where said rim meets said seam, said gap resulting from a step in said rim formed by said double thickness of said seam in combination with a single thickness of said sheet remote from said location.
