Oct. 29, 1935. o. L. ISACSON BOX FOR PACKING EGGS AND SIMILAR FRAGILE OBJECTS Original Filed Sept. 29, 1932 new To R Patented Oct. 29, 1935 UNITED STATES BOX FOR PACKING EGGS AND SIMILAR FRAGILE OBJECTS Oscar Leonard Isacson, Gothenburg, Sweden Original application September 29, 1932, Serial No. 635,415. Divided and this application February 23, 1934, Serial No. 712,622. In Sweden June 6, 1932 1 Claim.

The present invention relates to boxes for packing eggs and similar fragile objects of simple construction and cheap to manufacture and which ofier a reliable protection for the objects 5 packed therein.

The invention is described and claimed'in my pending patent application filed September 29, 1932, Ser. No. 635,415, from which this application is divided out.

According to the invention the box consists in a single rectangular blank of pasteboard (for example corrugated pasteboard) provided with a plurality of creasing lines disposed parallel to each other and dividing the blank into a plurality of rectangular sections, certain of said sections having seats for the eggs, the remaining sections being folded along the creasing lines to form a casing of substantially rectangular cross section surrounding said section having the egg seats therein, the latter extending diagonally from one longitudinal edge of the casing and all the way to the diametrically opposite edge thereof.

An embodiment of the invention, intended for the packing of eggs, is shown by way of example in the accompanying drawing, in which Fig. 1 shows a plan of a box blank, Figure 2 is a section through the box blank along the line IIII in Figure 1; and Figure 3 is a cross section on a larger scale, through the blank completely erected to form a box.

According to the embodiment shown the rectangular blank is provided with five transverse creasing or folding lines I, 2, 3, 4, 5 parallel to each other and dividing the blank into six rectangular sections 6, 1, 8, 9, I0, ll of which the four inner sections are in two pairs of equal size. In the outer, wider section 6 there is provided a series of seats for the eggs formed by slots l2, l3 crossing each other two by two.

When packing the eggs the sections 6 and I are folded upwardly along the creasing line 2 at right angles to the other sections, whereupon the section 6 with the seats is folded through a further 135 along the creasing line I so that its free edge will come near the creasing line 3. After having placed the eggs in their seats by bending down the flaps I4 formed by the slots [2, l3 the sections 9 and I are folded so that they, together with the sections 1 and 8, form a casing surrounding the eggs (see Figure 3), whereupon the outer section I I is folded into the casing and the adjacent edges of the sections 1 and ID are connected by means of a gummed strip IE5 or the like.

It has proved to be very convenient to use as 10 material for the blank corrugated pasteboard, the corrugations of the pasteboard running at right angles to the creasing or folding lines which contributes to stiffen the packing box and to make it resistant against strains.

What I claim is:

A combined egg support and box therefor formed from a single rectangular blank of material provided with creasing lines disposed parallel to each other and each extending to the opposite extremities of said rectangular blank to provide a plurality of rectangular sections of equal length one of said sections being of greater width than the remaining sections and having a plurality of egg receiving seats therein, each of said egg receiving seats being capable of receiving a single egg and said seats being arranged throughout the entire length of said section provided with the same, certain of the remaining sections being folded along their creasing lines toform the opposed sides, bottom and cover for the box, leaving the opposite ends of the box so formed opened, said section of greater width and having the egg holding seats therein being bent upon its creasing line so as to extend diagonally from one of the upper longitudinal edges of the box and its opposite or free end extending adjacent to one of the lower longitudinal edges of the box whereby the eggs seated within the seats thereof will extend at right angles thereto and means for connecting the free ends of said blank together whereby the various sections of the blank may be retained in the positions so formed.

OSCAR LEONARD ISACSON.
