Claims
- 1. A sidewall blank for a beverage container comprising:a first section having top and bottom opposite edges defining a first predetermined height and first and second opposite side edges, a second section having top and bottom opposite edges defining a second predetermined height which is greater than said first predetermined height and first and second opposite side edges, said first section being joined to said second section by a fold line such that said second side edge of said first section is contiguous said first side edge of said second section, said first section being so aligned with said second section that the height of said top edge of said first section is lower than the top edge of said second section, a first tab extending between a point on said top edge of said first section near said second side edge thereof to said top edge of said second section at said first side edge thereof, thereby to help prevent liquid from seeping into a top curl when said blank is formed into said beverage container, a second tab extending out from said second side edge of said second section, thereby to overlaps and seal said first tab when said blank is formed into said beverage container.
- 2. The sidewall blank of claim 1 wherein said first tab is generally triangular.
- 3. The sidewall blank of claim 1 wherein said second tab is generally rectangular.
- 4. The sidewall blank of claim 1 wherein said first tab is generally triangular and wherein said second tab is generally rectangular.
- 5. The sidewall blank of claim 1 wherein said first section is homogeneously integral with said second section.
- 6. The sidewall blank of claim 1 wherein said first tab extends from said top edge of said first section to the junction of said first edge of said second section and said top edge of said second section.
- 7. The sidewall blank of claim 1 wherein the height of said bottom edge of said first section is higher than the bottom edge of said second section.
- 8. The sidewall blank of claim 1 wherein said top and bottom edges of said first and second sections are curved.
- 9. The sidewall blank of claim 1 wherein said first section has been folded against said second section to form a folded blank, said folded blank has been formed into a cylinder with a side seam, and a bottom has been attached, whereby said blank has been formed into a cup.
- 10. A method of making a beverage container, comprising:providing a sidewall blank having a first section having top and bottom opposite edges defining a first predetermined height and first and second opposite side edges, and a second section having top and bottom opposite edges defining a second predetermined height which is greater than said first predetermined height and first and second opposite side edges, said first section being joined to said second section at a junction line such that said second side edge of said first section is contiguous said first side edge of said second section, said first section being so aligned with said second section that the height of said top edge of said first section is lower than the top edge of said second section, providing a first tab extending between a point on said top edge of said first section near said second side edge thereof to said top edge of said second section at said first side edge thereof, providing a second tab extending out from said second side edge of said second section, folding said blank at said junction line so that said first and second sections lie adjacent each other, face to face, so as to form a folded blank having a fold edge at one side thereof and two open edges at the opposite side thereof, and so that a top of said second section adjacent said top edge thereof extends above said top edge of said first section, forming said folded blank into a cylinder and joining said fold edge to said two open edges to form a side seam, and joining said second tab to said first tab, attaching a bottom section to said cylinder, rolling said top of said second section to form a top curl, whereby said first and second tab help prevent liquid in said container from seeping into said top curl.
- 11. The method of claim 10 wherein said first tab is generally triangular.
- 12. The method of claim 10 wherein said second tab is generally rectangular.
- 13. The sidewall blank of claim 10 wherein said first tab is generally triangular and wherein said second tab is generally rectangular.
- 14. The sidewall blank of claim 10 wherein said first section is homogeneously integral with said second section.
- 15. The sidewall blank of claim 10 wherein the height of said bottom edge of said first section is higher than the bottom edge of said second section.
- 16. The sidewall blank of claim 10 wherein said top and bottom edges of said first and second sections are curved.
