Application November 7, 1933, Serial No. 696,969

7 Claims. (01. 229-30) -in which the sides and bottom are integral, being formed of a properly shaped and folded cardboard blank. I reenforce the perimeter of the open end of the carton by means of a metallic reenforcing band so united with the sides of the carton that it will not be exposed to contact with the contents of the carton nor visible so as to become unsightly because of corrosion. This reenforcing band is so applied to the perimeter of the carton that it will reenforce the latter so that it will maintain its proper form.

One form which the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawing, in which:

Fig. 1 is a perspective view of a completed carton constructed in accordance with my present invention. 7

.Fig. 2 is an illustration of the cardboard blank by forming the bottom and sides of-the carton.

Fig. 3 is a perspective view of the reenforcing band prior to its being formed and applied to the carton.

Fig. 4 is a perspective view of the carton shown inverted and in the process of manufacture.

Figs. 5, 6, 7, and 8 are fragmentary views in section through the perimeter of the carton showing the steps of applying the reenforcing band thereto.

Referring more particularly to the accompanying drawing, l indicates a carton formed principally of cardboard or like sheet material. This carton is formed of an imperforate bottom II and side walls l2. The upper end of the carton is open as illustrated. It should be pointed out that the area of the bottom of the carton is slightly less than its open upper end so that the cartons will nest properly so that they may be packed and shipped economically.

The carton is formed from a blank Id of cardboard or like sheet material. This blank is cruciform in plan and comprises a square central section l5 forming the bottom of the carton and integral with which are sections l6 forming the sides of the carton. The blank may be scored along the broken lines I! to enable the'sections It to be folded relative to the section IE to form the carton; The sections I6 may be scored along the broken lines l8 and I9 for the reception of 5 a. reenforcing band as will be hereinafter described. a

By reference to the drawing, it will be noted that the perimeter of the open upper end of the carton is reenforced by means of a circumscrib- 10 ing reenforcing band 20. This band is constructed as illustrated in Fig. 3 .where it will be notedthat it consists of a strip of metal of angle cross section. At intervals one toe of the angle is formed with cut-away portions 2|. These cutaway portions occur at the corners of the carton. To apply the band to the carton it -is bent into the form of a square agreeing in dimensions with the upper end of the carton with the corner bends occurring centrally of the cut-away portions 2|. 1 The band is then applied to the carton with the uncut flange adjacent the outer surface of the carton and with the cut flange uppermost and extending laterally outward from the sides of the carton. The band is positioned with its upper edge in alignment with the scoring l8 of the side sections l6 of the blank, as shown in Fig. 5, and the upper ends of the side Walls of the carton are then bent laterally outward over the laterally outward extending flange of the reenforcing band, as shown in Fig. 6. .At this time the scoring l9 of the sides of the carton will align with the outer edge of the laterally and Qua wardly directed flange of the reenforcing band. The extremities of the sides are then folded over the laterally projecting flange of the reenforcing band, as illustrated in Fig. 7. After this has been accomplished, the laterally projecting por- I tion of the sides of the carton together wtih the laterally extending flange of the reenforcing band are folded against the sides of the carton, as illustrated in Fig. 8. As the reenforcing band will retain this position, the folded extremities of the carton will be properly clamped in place between the toes of the band.

It will be seen that when the carton is completed, the reenforcing band 29 will be entirely concealed so that it will not become unsightly due to corrosion and will not .come in contact with the contents of the carton. However, the provision of the'reenforcing band wil give the carton sufficient rigidity so that it will retain its proper form. 1

In practicing my invention, the carton is constructedby forming the blank M of cardboard or similar sheet material. If the carton is of comparatively heavy material, it may be scored along the lines l1, l8, and I9. However, when using certain sheet materials, such scoring will be unnecessary. The reenforcing band20is then formed and bent into a rectangular shape with the comer bends occurring centrally of the cut-away portions 2|. When properly bent, the reenforcing band will outline asquare agreeing in dimensions with the perimeter of the carton at its upper end. The side sections of the blank are then folded relative to the bottom section and the reenforcing band is applied thereto as illustrated in Fig. 5. The extremities of the side sections are then bent laterally outward as illustrated in Fig. 6, the bend occurring along the scoring lines l8 in register with the upper surface of the reenforcing band 20. The extreme ends of the side sections l6 are then bent over the laterally projecting toe of the reenforcing band 20, as illustrated in Fig. '7, and thereafter the laterally projecting portions of the side sections l6 and the reenforcing band 20 are folded against the exterior surfaces of the side sections l6, as illustrated in Fig. 8, firmly clamping the extremities of the side sections IS in folded position.

In the manufacture of the carton the fcregoing operations may be either performed manually or by means of machines. It will be noted that the reenforcing band is so covered by the cardboard material of which the carton is principally composed that it cannot come in contact with the contents of the carton. Likewise, its surfaces will not be exposed to the eye so that in the event 1 of any corrosion of the reenforcing band, the carton will not become unsightly.

It will be noticed also that the carton is con- 'structed so that its bottom area will be less than its top area, thus enabling the cartons to be nested: when constructed so that the packing and shipping costs will be minimized. 7

From the foregoing it is obvious that I have provided a carton which is durable in construction and which will be comparatively inexpensive to manufacture and while I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. A carton formed of a cardboard blank folded to form a bottom and sides upturned therefrom,

a reenforcing member of angular cross section circumscribing the-sides at the upper end of the carton, the upper extremity of the sides being passed around said member and said member being folded upon itself to grip the sides and be concealed thereby. I

2. A carton formed of a cardboard blank folded to form a bottom and sides upturned therefrom, a metallic reenforcing band arranged exteriorly of the sides and circumscribing the carton at the upper end thereof, the upper extremity of the sides and said reenforcing band being interfolded to form a reenforced edge comprising two thicknesses of metal and three thicknesses of cardboard.

of a cardboard blank shaped and folded to form a bottom and sides upstanding from the bottom, a metallic reenforcing band arranged at the exterior of the sides at the upper end of the carton and completely circumscribing the carton, said band having a portion lying parallel to and in contact 'with the exterior surface of the sides, said reenforcing band having portions over which the extremity of the sides may be folded, said latter portions being folded against the former portions to secure the extremities of the sides folded thereover.

5. In a cardboard carton, a reinforcing memmember folded over the edge of the cardboard to strengthen the same, said cardboard being folded adjacent its edge to surround and conceal the metallic member.

6. In a cardboard carton, a reinforced edge comprising a metal strip folded to grip the cardboard at, its edge and interfolded with the cardboard to be concealed thereby.

7. In a cardboard carton, a reinforced edge comprising a metallic member so interfolded with the cardboard that it will cover and protect the edge thereof and be surrounded and concealed thereby.
