Apparatus And Method For Forming Foldable Material Trays
First Claim
1. An apparatus for forming a foldable material tray, the apparatus comprising:
- a. a mandrel including a frame defining an aperture; and
b. a forming plate selectively positionable within the aperture to define a space between the frame and the forming plate having a width less than a thickness of at least a portion of the tray formed of the foldable material.

Abstract
An apparatus and method for forming a tray is provided including a forming plate and the complementary aperture in the mandrel formed to define a space therebetween that deforms the blank into the desired shape of the tray. The space between or tolerance defined by the forming plate and the mandrel is less than the actual thickness of the tray at one or more sections and/or points on the tray, such as at the corners of the tray, in order to crush the foldable material forming the tray at the one or more sections. The crushing of the foldable material at these sections effectively removes any shape memory from the foldable material, such that the tray including the crushed sections retains the shape of the tray without the need for additional securing materials on the tray but without degrading any leak-proof functionality of the tray.
