Abstract

The typical “single tray-brick” packing is achieved using two pieces of Expanded PE foam end-caps, from the top and bottom, surrounding the tray-brick in all directions. Shock absorbance is effected by the compression of the foam material itself; usually resulting in the need of a significant thickness of the end-cap’s wall. This paper describes a design of a “Single-Tray Brick” end-cap that enables shock-absorbance by mechanical means, using a flexible/moveable set of flanges and is of a smaller volumetric size as current expanded Foam End-Caps. The design supports a stack of six Jedec Trays (called a “Tray-Brick”) at both ends instead of the current top/bottom support. It is compatible with both Jedec CO-029 as well as Jedec CO-034 tray types.

Introduction

Current Tray-Brick end caps are made of Expanded Poly Ethylene (EPE) material. This is a highly specialized material with limited sources for the raw material (PE unexpanded beads form).  The fabrication of the EPE end-caps also uses a steam-molding method instead of the more common injection molding.  These two factors, the limited supply of raw materials and limited fabrication sites result in a very limited supply source for the end-caps.  At times, the light-weight but bulky end-caps are shipped from Asia to the USA, with high freight charges.  On occasion, they are even air-freighted (with freight charged by volume rather than by weight) for u...
