Abstract
The present disclosure relates to a mesh container and a method of making a mesh container that has a first and a second set of opposing side panels, a bottom panel, and a rim directed outwards from the upper edges of the side panels. At least two adjacent sides panels of the container and portion of the rim directed outwardly from the upper edge of the side panels are made from a sheet metal precursor with least one perforated and a stretched portion and unstretched metal portion. The precursor is folded so that the unstretched metal portion joins the two side panels and is bent to form the rim. A notch is cut from the edge of the unstretched metal portion where it is bent at the corner formed by the two side panels.

A method for producing a container made of a metal mesh, the container comprising first and a second set of opposing side panels that form four sides of the container with four corners, a bottom panel joined to the first and second sets of opposing side panels, and a rim directed outwardly from upper edges of the side panels and extending around at least one of the four corners, wherein the method comprises:
- perforating a web of sheet metal to form at least one perforated portion and at least one unperforated portion;
- expanding the at least one perforated portion along an expansion direction to form a web having metal mesh portion and unstretched metal;
- cutting at least one precursor from the web, the precursor comprising both metal mesh and unstretched metal;
- and
- folding the at least one precursor to form in one piece at least a portion of the container, the portion of the container comprising at least two side panels, one from each of the first set and second sets of side panels, that are adjacent and form a corner, the at least side panels being joined by the unstretched metal that is bent to form at least a portion of the rim the extends outwardly from the adjacent side panels and bent at a corner of the container defined by the adjacent side panels;
- wherein the precursor has a notch extending inwardly from an edge of the unstretched metal where the portion of the outwardly extending rim is bent at the corner of the container.
A mesh material container, comprising:
- a first and a second set of opposing side panels;
- a bottom panel;
- and
- a rim directed outwardly from upper edges of the side panels;
- wherein at least one side panel in the first set of side panels, one side panel in the second set of side panels, and at least a portion of the rim are folded from one piece of material comprising expanded sheet metal mesh and at least one unstretched sheet metal portion with an outer edge;
- wherein the at least one side panel in the first set of side panels and the at least one side panel in the second set of side panels are joined by the unstretched sheet metal portion and the at least one unstretched metal portion has been bent to form at least a portion of the rim and bent to form a corner of the rim;
- and
- wherein a notch is cut in from the outer edge of the unstretched sheet metal at the location of said corner.
A method for producing a container in mesh material, the container comprising expanded sheet metal, the container having a first and a second set of opposing side panels, a bottom panel, and a rim directed outwards from the upper edges of the side panels (21, 23), the method comprising:
- perforating and expanding a web of sheet metal along an expansion direction to form said mesh material, while leaving at least one portion of the web unstretched,
- cutting at least one precursor from the web,
- folding a container including said at least one precursor wherein said at least one precursor makes up, in one piece, at least a side panel in the first set of side panels and a side panel in the second set of side panels, which are joined by said unstretched portion which is bent to form a corner of the rim, wherein the unstretched portion is cut such that a tab projects from the edge of the unstretched portion where said corner of the rim is to be made.
A mesh material container from in part from expanded sheet metal mesh and in part from unstretched sheet metal, the container having a first and a second set of opposing side panels, a bottom panel, and a rim directed outwards from the upper edges of the side panels;
- wherein
- at least one side panel in the first set of side panels and one side panel in the second set of side panels are made in one piece with an unstretched portion of sheet metal joining them;
- the unstretched sheet metal is bent to form at least a portion of the rim that is also bent at a corner of the container;
- and
- an edge of the unstretched portion of sheet portion is cut to form a tab extending from the edge at the location of the corner of the container such that, when bent, the rim has a substantially uniform cross section throughout the corner.
