Abstract
Abstract A device is disclosed for packaging a stack or stacks of sheet articles such as sheets of glass. The device comprises a rectangular frame formed of two L-shaped sections and is positioned around a stack of sheet articles. A panel or floor member is disposed between one side of the frame and a face of the stack so that the edges of the sheet articles of the stack rest upon the floor member. On both ends of the floor member there are mounted stops which abut faces of the stack to prevent movement of the stack with respect to the frame. Protective panels may also be mounted on the frame to extend over at least a portion of a face of the stack to protect or to enclose the packaged sheets. The L-shaped sections of the frame may be assembled in various positions so as to vary the dimensions of the opening of the frame to accommodate stacks of various crosssectional areas. The package may also comprise two or more frames with each frame made of a U-shaped section and a crosspiece to bridge the open ends of this section.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
A packaging device for a stack of sheet articles comprising a frame including at least two L-shaped sections, each section comprising first and second arms, the first arms having slot means therein, the second arms of each L-shaped section being received in its respective slot means and being secured therein, said L-shaped sections being oppositely disposed around a stack of sheet articles such that the sheets are pressed against each other, the second arm of at least one of said L-shaped sections being received in the slot means of the opposed L-shaped section and being slideable therein for varying the relative dimensions of said frame, stop means engaging opposed faces of said stack and limiting movement of the sheet articles outwardly for said frame, and panel means supporting another face of said stack and interconnecting said stop means and the first arm of at least one of said L-shaped sections.
Claim 2
Dependent Claim
150 words
