Abstract

This invention relates to a lightweight, high strength disposable or recyclable corrugated collapsible container pack providing a compact collapsed shipping container including an integral corrugated pallet and providing top or side access in the erected state.

Corrugated leg wrap supports utilizing a sheet of corrugated material having a plurality of score lines folded inwardly forming a generally rectangular conduit support member are used in combination with at least one corrugated sheet to form a corrugated pallet. Within the hollow conduit of the leg wrap supports, individual support members are formed from one or more layers of a narrow strip of corrugated material having a plurality of scores cut therein along the surface of one side for bending the strip into a generally square configuration. The flutes of the corrugated material comprising the support member and opposing panel support legs are oriented in the vertical plane to maximize the strength to weight ratio.

Claims

1. A corrugated collapsible container pack, comprising:

a tray having a side edges bent upwardly forming four vertical tray side panels and a central floor panel, permanently attaching three of said four tray side panels forming two secured corners and removably attaching said remaining tray side panel with means for releasably securing said adjacent tray side panels forming a pair of detachable corners;

a corrugated pallet comprising at least one flat sheet and at least two leg wrap support members, each of said leg wrap support members comprising a sheet of corrugated material having a plurality of spaced apart parallel score lines formed therein, said sheet being folded inwardly forming creases along said score lines and at least five panel sections thereinbetween forming a generally rectangular shaped conduit having at least two of said panel sections overlapping and secured together with a holding means, said leg wrap support member including at least two spaced apart and aligned transverse slots formed through the sides of said support member, and said leg wrap support member including at least one support member therein, said corrugated pallet being positioned within said tray;

side wall sheets having a central panel and a pair of side panels disposed between said pallet and said tray;

a lid having side edges bent upwardly forming four vertical lid side panels and a central top panel, permanently attaching three of said four lid side panels forming two secured corners and removably attaching said remaining lid side panel with means for removably securing said adjacent lid side panels forming a pair of detachable corners, said lid being placed over the top of said side wall sheets;

a plurality of vertical support members for supporting said lid in the collapsed position in cooperative engagement with said tray, enclosing said side wall sheets therein; and

said detachable tray corners and said detachable lid corners being in alignment one with the other defining means for releasing said detachable lid corners of said vertical tray panel and said vertical lid panel for removing one of said side wall sheets and providing side access to the contents stored within said corrugated collapsible container pack during the erect position without removing said lid.
