A shipping carton which contains other product cartons is designed so that it can be cut open with a knife without exposing the contained product cartons to damage by the knife. At least one side wall of the shipping carton is inwardly bowed so that the inner product cartons will be shifted away from the edges of the bowed side wall thereby leaving an internal void adjacent to the edges of the bowed side wall. A knife can be inserted through the edges of the bowed side wall into the void to cut the shipping carton without cutting the inner product cartons.

A corner post made of folded corrugated paperboard is inserted into the corner areas of cartons containing, for example, large appliances, such as stoves, refrigerators, washing machines, or the like. The corner post is a multi ply device which ensures that there will be adequate space between the appliance and the carton wall, and which provides strength for the carton so that multiple filled cartons can be stacked on top of each other. The post is provided with fold lines which are made up of alternating cuts and scores to provide for easy folding of the post. The post is machine folded and glued to a flattened form which is suitable for bulk shipment. The post is easily transformed from the flattened to the erected form and inserted into the corner areas of the cartons.

A box for storing files is formed from a single blank of paperboard. The blank consists of a centrally located bottom wall panel having side wall panels foldably connected thereto. Each of the centrally located bottom walls panels and side wall panels have an end wall panel extending from a transverse edge thereof so that when the side wall panels are folded 90.degree. relative to the bottom wall panel, the end wall panels on the transverse edges of the side walls and bottom walls can be overlapped and locked together. Connected to the outer longitudinal edges of each of the side wall panels is a top wall panel substantially half the width of the centrally located bottom panel. The top wall panels are adapted to be folded 90.degree. relative to the side walls to form a cover for the box. Longitudinally extending tabs extend from the transverse edges of each of the top wall panels and can be inserted within an opening in the end walls to lock the top wall panels in place on the box.

File box

A pad for use under an object such as a freezer or refrigerator which has a metal bottom plate and distended supports. The pad has at least two flaps along its lateral sides which fold together to form elongated cushion members with aligned die cut apertures into which the supports can be fitted.

Die cut pad

A die cut pad made from corrugated paperboard for use in protecting a sink during shipment in a rectangular carton, the pad being one which folds over upon itself and has a die cut section which may extend down into the cavity in a similarly placed section on the opposite side which is positioned against the outside of the cavity and serves to hold the sink or suspend it away from the side panels of the carton.

Restraining pad for sink packages

A self-locking outside corner pad of sheet material and adapted for use with thin rectangular objects such as window frames or doors. The pads have adequate thickness and suspension structure to allow stacking, even without an outer sleeve.
