Abstract
A mesh container two sets of opposing sides, a bottom, and a rim extending outwardly from the top of the sides is folded from one or more precursors cut from a web comprising a mesh portion formed by perforating and stretching part of a sheet and an unstretched portion. Each precursor is single piece that is folded into at least two side panels made at least partly of mesh and a portion of the outwardly extending rim made of the unstretched portion of the web. One or more portions for a bottom panel may be included with the two side panels, the bottom of the container being formed by folding the bottom panel portions away for the side panels to form an overlapping joint with each other.
Claims12
A method for use in making a metal mesh container that comprises four side panels made at least partly of metal mesh, a bottom panel made of metal mesh, and a surrounding metal rim extending outwardly from top edges of the side panels and made of solid metal;
- the method comprising:
- cutting first and second precursors from a web of sheet metal comprising one or more portions that have been perforated and expanded along an expansion direction to form metal mesh, and one or more unstretched sheet metal portions, each of the first and second precursors having at least one solid metal portion from the one or more one or more unstretched portions of the web of sheet metal and at least one metal mesh portion from the one or more portions of web of sheet metal that have been perforated and expanded;
- and
- for each of the first and second precursors, folding the precursor to make up in a single piece first and second adjacent side panels for the metal mesh container, part of the bottom panel, and a portion of the surrounding metal rim extending outwardly from top edges of the first and second side panels, wherein
- the first and second side panels are at least partly made of metal mesh from the one or more metal mesh portions, and
- the portion of the surrounding metal rim joins the first and the second side panels and is formed from the at least one solid metal portion;
- and
- assembling the folded first and second precursors to form the four side panels of the mesh container from the first and second adjacent side panels from the first and second folded precursors and the bottom panel from the part of the bottom panel of from the first and second folded precursors.
A method for use in making containers that comprise sides made at least partly of metal mesh and a surrounding metal rim extending outwardly from the sides not made of mesh, the method comprising:
- cutting one or more precursors from a web of sheet metal comprising one or more portions that have been perforated and expanded along an expansion direction to form metal mesh, and one or more unstretched sheet metal portions;
- and
- for each of the one or more precursors, folding the precursor to make up in a single piece at least a first side panel for a metal mesh container and an adjacent second side panel for the metal mesh container, and at least a portion of the surrounding metal rim extending outwardly from top edges of the first and second side panels, wherein the first and second side panels are at least partly made of metal mesh at least a portion of the rim joins the first and the second side panels and is formed from one of the one or more unstretched sheet metal portions;
- wherein:
- the one or more unstretched sheet metal portions comprise an unstretched leading portion and an unstretched trailing portion of the web of sheet metal, with an intermediate portion of the web of sheet metal between the unstretched leading and trailing portions comprising the metal mesh;
- the one or more precursors comprise a first precursor and a second precursor formed by cutting across the intermediate portion of the web of sheet metal, the first precursor comprising the leading unstretched portion and the second precursor, comprising the trailing unstretched portion, the first and second panels in each of the first and second precursors containing mesh from the intermediate portion of the web of sheet metal;
- each of the first and second precursors further comprises a bottom panel portion connected to the first side panels;
- and
- folding includes folding each of the bottom panel portions away from the first side panel, the bottom panel portions from a set of opposing first side panels of the mesh container partly overlapping midway between opposing first sides panels;
- and wherein the method further comprises forming a joint between the first and second bottom panel portions where the first and second bottom portions overlap.
