UNITED STATES PATENT OFFICE.

' SHEET-METAL BOX.
- ence marked thereon.
the'cover applied to the box.
The invention relates to new and useful improvements in sheet metal boxes, and more especially to boxes which are stamped up in a single piece from sheet metal and are so constructed that one box may be nested within another, during shipment.
An object of the invention is to provide a box of the above character, with a supporting flange at its upper edge, on which the nested boxes rest so as to prevent the sides of the boxes from wedging together.
A further object of the invention is to provide a box of the above construction with a coating of sealing material, which is placed inside of the curled flange on the body of the can, whereby the curled portion of the flange protects the coating, and properly houses the same.
These and other objects will in part be obvious, and will in part be hereinafter more fully described.
In the drawings which show by way of illustration one embodiment of the invention, Figure 1 is a sectional view through a plurality of boxes, which are nested together, each of which embodies my invention. Fig. 2 is an enlarged detail showing the flange on the body of the box with the coating applied thereto, and before said flange is curled to protect the coat. Fig. 3 is a similar view showing the flange after it is curled, and also Fig. A is a similar view showing the flange on the cover, and the flange on the body of the box, rolled into a double seam. Fig. 5 is a plan view of a box having my improvement applied thereto.
In carrying out the invention, I preferably form the body of the box from a single piece, by stamping the same from tin plate or other sheet metal which may be coated with a non-corrosive substance. From certain aspects of the invention however, the sheet metal may be the ordinary black sheet having the inner surface thereof coated with lacquer, aluminum, or any other non-corrosive material.
Specification of Letters Patent.
Application filed June 4. 1912.
Patented Nov. 25, 191 3. Serial No. 701,492.
The invention relates more particularly to the construction of the box, and not t the material fro-m which the box is made. Said box is formed with the sides thereof tapering o slightly outwardly toward their upper edg s. whereby one box may be nested within the other. The upper edge of the box is formed with a flange which may be trimmed to the proper width. The under face of the flange 5 is coated with a suitable plastic sealing material, after which the outer edge of the flange is curled downwardly and inwardly, so as to provide a part projecting underneath the packing to protect the same, and this projecting part of the flange also serves as a support f r the cans when nested together.
Referring more in detail to the drawings,
the invention consists of a metal box 1, which is as above noted, stamped from a single 7.5
sheet of metal. The sides 2, of the box are tapered outwardly toward the upper edges 3 thereof. The bottom of the box is formed with a downwardly projecting bead4. This head 4 is located within the margin of the so bottom of the box, and between said bead and the margin of the box, said bottom is scored. The purpose of this head and the scoring formed in the bottom, is to provide an easy way of opening the box. When the box is closed, if pressure is applied to the head 4 either by striking or otherwise, said bottom will be sheared off at the score 5, thus giving access to the contents of the box.
This construction of the bottom of the box forms no part of the present invention, but is shown, described and claimed, in my copending application, Serial No. 304,508, filed March 6th, 1906.
The upper edges 3 of the box 1 are bent outwardly to form a flange 6. This flange may be trimmel so as to form a uniform flange of the desired width. The under face of the flange is coated with a coating roll or other means, so as to provide a. strip of sealing material 7, which extends entirely around the flange on the box. After the coating is applied to the under face of the flange, said flange is curled as at 8 downwardly and inwardly, to provide an inwardly' projecting lip 9, which projects over the coating applied to the flange.
When the boxes are nested as shown in Fig. 1, this lip 9 on the curled part of the flange, will rest on the upper face of the flange of the box in which it is placed, and said inner box will thereby be supported by the flange solely of the next adjacent outer box. In other words, this downwardly turned part of the flange is so proportioned that the inwardly bent part is spaced from the outwardly bent part of the flange, and this inwardly bent part supports the boxes when they are nested, and thereby prevents the side faces of the boxes from wedging together, so as to permit the same to be easily separated. By this construction, I anrable to nest together for shipment, a number of boxes and thus reduce to a minimum the cost of shipment. Furthermore, when said boxes are nested, the packing or the sealing material, will be efl'ectively housed between the flanges of the boxes, and kept free from dust and dirt, and also from abrasion during transportation.
The cover 10 is shaped so as to fit within the upper end of the box, and is formed with a flange 11 adapted. to rest upon the flange formed in the body'of the box, and also to be rolled into a double seam with said flange on the box body. In Fig. 3 I have shown the cover in place on the body of the box, with the flange projecting laterally therefrom. In Fig. 4, I have shown the two flanges rolled into a double seam and the packing or sealing material as effectively closing or sealing said double seam. This roll or curl on the outer edge of the flange of the body of the box not only serves as a means for protecting the sealing material and as a means for supporting the boxes when nested, but will also aid in the forming of the double seam as the flange is thereby given an initial curl, which not only assists in rolling the same into a double seam, but also assists in the proper rolling of the flange on the cover into said double seam.
It is obvious that minor changes in the details of construction and in the shape of the box may be made, without departing from the spirit of the invention as set forth in the appended claim.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
A sheet metal box consisting of a bottom and side walls, said side walls being slightly tapered outwardly toward their upper edges, whereby one box may nest another, said side walls at their upper edges being bent outwardly to form a flange, said flange having a coating of sealing material applied thereto on its under face, the outer edges of said flange being bent downwardly and inwardly, said inwardly bent portion of the flange being spaced from the outwardly bent portion thereof, whereby said sealing material is protected, and a support is formed for the nested boxes which prevents said nested boxes from wedging together.
In testimony whereof, I aflix my signa ture, inthe presence of two Witnesses.
EDWIN NORTON.
