1. A carton, comprising:
- a top closure;
a plurality of side panels;
a plurality of auto-bottom panels each foldably connected to a bottom edge of one of said side panels; and
a plurality of spacer panels foldably connected to at least some of said auto-bottom panels;
said top closure comprising;

an inner mandrel panel foldably connected to said second inner cover flap, and adapted to be folded into said carton where said inner cover flaps meet;
a second slot beginning in said inner cover flap and continuing into said inner mandrel panel, said second slot being coplanar with said first slot;
an outer cover flap foldably connected to a third one of said side panels; and
an outer clamping panel foldably connected along a distal edge of said outer cover flap;
said outer cover flap being foldable over said inner cover flaps with said outer clamping panel extending through said first and second slots and generally axially into the portion of said second slot defined in said inner mandrel panel;
such that when said carton is erected, said auto-bottom panels form a generally planar bottom of said carton, and said spacer panels extend generally axially into said carton from said bottom to form a two-dimensional support base for holding an object at a location spaced above the bottom of said carton, said carton being substantially unobstructed above said support base inside said carton when said top closure is opened, and said spacer panels defining a cross having an intersection point spaced inwardly from all of said side panels.

Abstract
A carton of foldable material protects an article packed therein by holding the article away from the bottom of the carton, and preferably by holding the article firmly, yet in a cushioning manner, in a position spaced away from all the exterior walls of the carton. The carton is assembled from a blank of foldable material defining a plurality of spacer panels foldably connected to automatic bottom panels, such that when the carton is erected, the auto-bottom panels form a generally planar bottom of the carton, and the spacer panels extend generally axially into the carton from the bottom to form a two-dimensional support base for holding an object at a location spaced above the bottom of the carton. A top closure includes a clamping member extending into the carton, such that when the carton is closed, the spacer panels and the clamping member are urged against opposite ends of the object within the carton, to hold the object therebetween.
