The present invention relates to a blank configured to form a collapsible bowl. The blank is intended to provide a device that can be easily transformed between a flat configuration and an erect configuration. The blank comprises, a first radial crease-line and a second radial crease-line, meeting at a centre point within the blank and forming a fold segment and a major segment. The major segment further includes an over-fold segment and an under-fold segment adjacent to the fold segment. The blank includes a base crease-line, that forms the boundary of the base section and the wall section. The blank is erected by rotating the fold segment around the center point until the over-fold segment overlaps the fold segment, and the under-fold segment underlays the fold segment. When erected the base section forms a conically shaped structure within the erected collapsible bowl.

A container having enhanced wall integrity with a rotational element and a stacking feature is provided. The container includes a sidewall having an alignment structure formed along a height of the sidewall and an upper stacking shoulder formed above the alignment structure. The alignment structure is adapted for orienting the container with respect to a second container so that the alignment structures of the containers become parallel with one another and the containers may be fully nested one within the other. The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. The upper stacking feature is formed into the sidewall of the container and includes a radially extending wall portion and an upwardly extending wall portion that together form a stacking corner. The stacking shoulder is provided above the alignment structure facilitates nesting of two containers when stacked together.

A disposable bowl press-formed from a generally planar paperboard blank. The bowl has a large capacity, wide flange for easy handling and exhibits excellent rim stiffness. The bowl can include a bottom panel, a sidewall extending upwardly and outwardly from the bottom panel and a flange extending outwardly from the sidewall. The flange includes a rim portion having an arched central crown with a convex upper surface defining a radius of curvature RC of 0.650 to 1.180; and annular transition from the rim portion defining a radius of curvature, R3, and an evert extending downwardly from the annular transition, R3, wherein the bowl has an outermost diameter D of about 8″ to about 10″ and a height to diameter ratio, H/D, of from 0.18 to 0.20.

A blown film of soil biodegradable aliphatic polyesters produced primarily from diacid and diol monomers. The diacid monomers may be of any type including succinic acid, adipic acid, and hexanedioic acid. The diol monomer may be of any type including ethylene glycol, propanediol, butanediol, and hexanediol. Commercial aliphatic polyesters produced from diacid and diol monomers include polybutylene succinate (PBS), polybutylene adipate succinate (PBAS), and polybutylene adipate (PBA). Comonomers may also be added. Such comonomers include chemicals with a single carboxylic acid, hydroxy, or amine moiety, which act as chain terminators, chemicals with three or more carboxylic acid, epoxy, and/or hydroxy moieties which, act as branching agents.
