CORNER GUARD FOR CARTONS Filed Jan. 16, 1939 ATTORNEYS Patented Jan. 2l, 1941 UNITED STATES PATENT 1 Claim.
This invention relates to corner guards for cartons and has for an object to provide a metal reinforcement which may be bound into a corrugated box or carton with prongs, one of the sections of the guard being free to permit it being folded down over another section to permit storage of the carton in flat condition, the
free section being unfolded along a weakened line to a position of 90 degrees which will permit the carton being opened and set up and the free section hooked in place to provide a corner reinforcement which will be light, strong and durable, and which will not easily get out of order.
With the above and other objects in View the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacricing any `of the advantages of the invention.
In the accompanying drawing forming part of this specication;
Figure 1 is a perspective view of a carton with a portion of the top broken away to expose a corner guard constructed in accordance with the invention.
Figure 2 is a cross sectional view taken on the line 2-2 of Figure l drawn to enlarged scale.
Figure 3 is a plan View of the blank from which the corner guard is formed.
Figure 4 is a side elevation of the corner guard in set up position.
Referring now to the drawing in which like characters of reference designate similar parts in the various views, the corner guard is formed from a single blank of metal in the form of a square divided by diagonal lines into four triangular sections of equal size, one of the sections being removed, as shown in Figure 3, except for two diagonally extending lugs IIJ on the adjacent section II. The blank is scored along the diagonal lines as indicated at I2 and I3 and the lower section I4 opposite the upper section II is provided with slots I5 to receive the lugs III when the blank is folded into pyramid shape to engage the corner of the carton in use.
The section I6 intermediate the` upper section II and lower section I4 is provided with struck out prongs I'I and the lower section is provided with struck out prongs I8. The corner guard above described is bound into the carton by lthe carton manufacturer inserting the prongs El and I8 of the sections I6 and I4 into two of the walls of the corner of the carton I3, as best shown in Figure l. As the carton must be delivered and stored fiat the lower section I4 and intermediate section I6 having the prongs must be folded flat along the weakened score line I2. When the carton is set up for use the operator, by the act of opening the carton unfolds the sections Hl and I6 on the weakened score line I2 to a position of 90 degrees relatively to each other. This will permit the top section II with the lugs i9, being folded down to engage the bottom section I4 whereupon the lugs I may be engaged through the slots I to set up the corner guard.
From the above description it is thought that n the construction and operation of the invention will be fully understood without further explanation.
What is claimed is:
A corner reinforcement for cartons, comprising a single blank of sheet metal of substantially rectangular contour divided by diagonal intersecting score lines into three contiguous triangularsections, there being openings in the free edge portion of one of the end sections, tabs on the free edge portion of the other end section adapted to be hooked into said openings, said sections being bent on the score lines to form a pyramid guard for insertion in the corner of a 'n i HERMAN E. STOCK.
