Abstract
A closure element is adapted for use with a cup to form a container when combined, the container configured to hold a beverage or a granular substance. The closure element comprises a sealing portion and an annular sealing wall extending around the sealing portion, the annular sealing wall is tilted with an angle alpha of between 2-8 degrees in relation the axis A and intended to be in contact with an inside surface of an annular inner wall of the cup to seal the container. The closure element further comprises a spout configured to deliver the beverage or granular substance to a user. The closure element is configured to be pressed into the cup so that the annular sealing wall engages the inside surface of the annular inner wall of the cup to form a tight seal between the closure element and the cup.
Claims21
A closure element adapted for use with a cup having a top opening with a first area A1 in a cross-sectional plane perpendicular to an axis A,
- said closure element and cup adapted to form a container when combined, said container extending along said axis A and configured to hold a beverage or granular substance,
- said closure element comprising:
- a sealing portion with a second area A2 in a cross-sectional plane perpendicular to said axis A, wherein the second area A2 is essentially equal to said first area A1;
- an annular sealing wall extending around said sealing portion, wherein said annular sealing wall is tilted with an angle alpha (α) in relation to said axis A and intended to be in contact with an inside surface of an annular inner wall of said cup to seal said container;
- and
- said closure element further comprises a spout configured to deliver said beverage or granular substance to a user;
- wherein said closure element is configured to be pressed into said cup so that said annular sealing wall engages said inside surface of said annular inner wall of said cup to form a tight seal between said closure element- and said cup, wherein said angle alpha is between 2-8 degrees,
- wherein said closure element is made of cellulose-based paper material or fiber-based paper material.
A container configured to hold a beverage or granular substance and extending along an axis A, the container comprising:
- a first cup made of cellulose-based paper material or fiber-based paper material, said cup comprising an opening with a first area A1 in a cross-sectional plane perpendicular to an axis A, wherein said cup comprises an inner annular wall tilted at an angle alpha (α) in relation to said axis A, and
- a closure element according to any previous claim.
