Compostable Or Recyclable Cooler
A tub for a container includes an inner tub and an outer tub, each formed of a solid compostable or recyclable sheet formed primarily of plant fiber. Both the inner tub and the outer tub include a floor, a plurality of side walls that are coupled to the floor along common edges and each coupled to two adjacent side walls along common edges, and a rim provided at a top of the side walls. The rim of the inner tub rests on and is secured to the rim of the outer tub such that the side walls of the inner tub extend downwardly into the space between the side walls outer tub, with the side walls of the outer tub surrounding and spaced apart from the side walls of the inner tub. A volume between the side walls of the inner and outer tub provides a cavity.

- 1. A tub for a cooler, the tub comprising:
an inner tub formed of a solid compostable or recyclable sheet formed primarily of plant fiber, the inner tub including
a first floor,
a plurality of first side walls that are continuously coupled to the first floor along first common edges and each continuously coupled to two adjacent first side walls along second common edges to surround an interior space of the tub, at least one of the plurality of first side walls providing a planar vertically-extending recess between two outwardly extending projections, and
a first rim provided at a top of the side walls, the vertically-extending recess extending from the first floor to the first rim; and
an outer tub formed of a solid compostable or recyclable sheet formed primarily of plant fiber, the outer tub including
a second floor,
a plurality of second side walls that are continuously coupled to the second floor along third edges and each continuously coupled to two adjacent second side walls along fourth common edges, at least one of the plurality of second side walls having a planar vertically-extending indentation extending inwardly into the vertically-extending recess provided between two outwardly extending projections of the at least one of the plurality of first side walls, and
a second rim provided at a top of the second side walls, the vertically-extending recess extending from the second floor to the second rim,
wherein the first rim of the inner tub rests on and is secured to the second rim of the outer tub such that the plurality of first side walls extend downwardly into the space between the plurality of second side walls with the plurality of second side walls surrounding and spaced apart from the plurality of first side walls, and wherein a volume between the plurality of first side walls and the plurality of second side walls provides a cavity.
- 23. A container, comprising:
an inner tub formed of a solid compostable or recyclable sheet formed primarily of plant fiber, the inner tub including
a first floor,
a plurality of first side walls that are continuously coupled to the first floor along first common edges and each continuously coupled to two adjacent first side walls along second common edges to surround an interior space of the tub, at least one of the plurality of first side walls providing a recess between two outwardly extending projections, and
a first rim provided at a top of the side walls; and
an outer tub formed of a solid compostable or recyclable sheet formed primarily of plant fiber, the outer tub including
a second floor,
a plurality of second side walls that are continuously coupled to the second floor along third edges and each continuously coupled to two adjacent second side walls along fourth common edges, at least one of the plurality of second side walls having an indentation extending inwardly into the recess provided between two outwardly extending projections of the at least one of the plurality of first side walls, wherein the indentation extends inwardly into the recess while maintaining a gap between the recess and the indentation, and
a second rim provided at a top of the second side walls, the vertically-extending recess extending from the second floor to the second rim,
wherein the first rim of the inner tub rests on and is secured to the second rim of the outer tub such that the plurality of first side walls extend downwardly into the space between the plurality of second side walls with the plurality of second side walls surrounding and spaced apart from the plurality of first side walls, and wherein a volume between the plurality of first side walls and the plurality of second side walls provides a cavity.
