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.
Claims17
A method for producing a container made of a metal mesh, the container comprising a 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:
- cutting at least one precursor from a web comprising a metal mesh portion and an unstretched metal portion, 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 two 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;
- and
- wherein the notch is formed with a tab in a middle of the notch.
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 upper edges of the side panels, 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.
