Abstract
A blank made of a polymeric material is provided and used to form the body of a drink cup or other container. A floor can be coupled to the body to define an interior region of the cup.
Claims16
A blank of polymeric material used to form a body of a cup, the blank comprising
- an upper band formed to include a curved top edge and
- a lower band formed to include a left-end edge, a right-end edge, and a curved bottom edge arranged to extend between the left-end and right-end edges, wherein the lower band is appended to the upper band along a curved fold line to locate the curved fold line between the curved top and bottom edges, the lower band is formed to include a series of high-density staves of a first density and low-density staves of a relatively lower second density, each stave is arranged to extend from the curved bottom edge of the lower band toward the curved fold line, and the high-density and low-density staves are arranged to lie in an alternating sequence extending from about the left-end edge of the lower band to the right-end edge of the lower band to cause density to alternate from stave to stave along a length of the lower band,
- wherein the lower band has a first side and an opposite second side, each low-density stave has a first face on the first side of the lower band, a second face on the opposite second side of the lower band, and a first thickness defined by a distance between the first and second faces of the low-density stave, and each high-density stave has a first face on the first side of the lower band, a second face on the second side of the lower band, and a second thickness defined by a distance between the first and second faces of the high-density stave, and the second thickness is less than the first thickness,
- wherein the second thickness is about half of the first thickness.

- an upper band formed to include a curved top edge and
- a lower band formed to include a left-end edge, a right-end edge, and a curved bottom edge arranged to extend between the left-end and right-end edges, wherein the lower band is appended to the upper band along a curved fold line to locate the curved fold line between the curved top and bottom edges, the lower band is formed to include a series of high-density staves of a first density and low-density staves of a relatively lower second density, each stave is arranged to extend from the curved bottom edge of the lower band toward the curved fold line, and the high-density and low-density staves are arranged to lie in an alternating sequence extending from about the left-end edge of the lower band to the right-end edge of the lower band to cause density to alternate from stave to stave along a length of the lower band, wherein each high-density stave has a narrow width and each low-density stave has a relatively wider wide width,
- wherein the narrow width is about 0.028 inch (0.711 mm) and the relatively wider wide width is about 0.067 inch (1.702 mm).
