Curtis, Cleveland, Ohio Application April 23, 1936, Serial No. 76,038 4 Claims. (Cl. 229—37) This invention is an improvement in boxes and box blanks and relates more particularly to con tainers for electrical condenser units which are adapted to be inserted and sealed therein. One of the objects of the invention is to con struct a box from a one piece blank cut from suit able sheet material and arranged to be folded to viding end portions for the convenient fastening of the box to a base or support. provide a reinforced base or support by which the The adjoining sections and end ?aps of the box may be rigidly supported on a ?at surface. 10 Another object is to provide a box having end blank are bent inwardly along the weakened or ?aps, a side wall extending beyond the box body, and an end cover ?ap adapted to form, with the extended end-of the side wall, an additional rein forcement for supporting the box rigidly upon a 15 ?at surface. A further object is to provide a simple, inex pensive and durable box formed from a single piece blank/and which is adapted to be folded so that but one surface of the blank will form the 20 complete outer surface of the box. In this man outwardly at “I, while the portions H are bent in an opposite direction at H. In this manner, when the blank is assembled, it will form a box of elongated form as shown in Figures 1 and 2. ner a blank comprising a sheet of stiff paper board having one surface in color or coated within ,. base for the box which is very desirable in mount ing the box upon a ?at suface in use. The sections l and 5 are of su?icient length that they overlie the extremities of the box when folded as illustrated in Figures 1 and 2, thus pro- 5 a metallic ?nish may be employed and the box when folded and assembled according to my in 25 vention, will have its complete outer or exposed surface thus materially enhanced in appearance. Other objects and adavantages of the inven tion will become apparent from the following de scription of an embodiment of my invention, 30 reference being made to the accompanying draw ing in which like reference characters are em ployed to, designate like parts throughout the . same. In the drawing: Figure 1 is a perspective view of an embodiment of invention showing the box assembled and the ends closed. Figure 2 isa similar view showing the box ends 40 partially open. Figure 3- is a sectional view taken on line 3-3 of Figure 1, and Figure 4 is a plan view of the blank from which the box is formed according to the illustrated 451. embodiment of the invention. I will ?rst proceed to describe the box blank illustrated in the drawing. The blank is out or stamped preferably from a single sheet of suitable materialwsuch as pasteboard, sheet metal or ?bre 50 and conliprises a plurality of side walls or sections, indicated at i, 2, 3, 4, and 5, the end flaps ‘i and 1, and the cover ?aps 8 and 9. The sections I and 5 overlie one another when the box is assembled, as indicated in Figures 1 to 3 inclusive, and in this manner provide a very rigid, reinforced bottom or scored lines. The cover ?aps 8 and 9 are bent l0 It is to be noted that by my invention I am en- 1'5 abled to form boxes of a sheet blank which is coated or has but one entire surface in color. In so folding the box the colored or coated ‘surface may be exposed on all sides of the box, thus giv ing a very pleasing appearance without neces sitating the coloring or coating of portions of 20 both the inner and outer surfaces of the blank sheet in order to insure a completely colored or coated outer appearance. Furthermore, by my invention I can accomplish this result without the necessity of using a composite blank or one com prising a plurality of separate parts. At I3 I have perforated the blank so as to pro vide openings for conductors at one end of the box. This structure is particularly desirable when the boxes are used to house electrolytic con denser pads to which electric conductors are attached. This a?’ords convenient means for connecting the pad in a circuit after it has been sealed in the box. The openings I 3 are prefer ably located at one end of the box and at points intersecting the sections 2, 3, and 4 and the ?aps ‘l and 9. V The end closure is simple and very durable and effective. 40 When the box is formed as in Figure 2 the end closures are completed by binding the flaps 8 or 9 downwardly to overlie the end ?aps E or ‘I re spectively, while the portion ll of the cover ?aps is bent outwardly to lie ?at against the extended 45 portions of the members I and 2 The adjacent faces of the members I and 2 may be secured together with adhesive, rivets, or in any other suitable manner. The box formed in accordance with my inven- 50 tion is not only pleasing in appearance, but is extremely simple in construction and very dura ble in use. Its durability is enhanced by the overlying members I and 2 and the reinforced end closures. ‘By folding the cover ?aps in the 55 2 . 2, 105,095 manner described the protruding ends of the box sive wall ends, said co-extensive walls and the are reinforced by three thicknesses of material extension 01.’ .said end closure having openings which prevent collapse or ?attening of the box formed therein which are adapted to register one even though it is ei?pty. , with another when the blank is folded and as Various changes may be made in the details of sembled.
