PROCESS OF MAKING METALLIC CONTAINERS Filed Dec. 13, 1929 Patented Jan. 5, 1932 PATENT OFFICE JOHN SINKO, OI CHICAGO, ILLINOIS PROCESS OF HAKING'IETALLIC CONTAINERS Application filed December 18, 1929. Serial No. 413,731.
This invention relates to metallic containers and to a process for makin the same. In the particular form illustrate herewith, the Container is a barrel-sha ed receptacle adapted for use as a bank. he invention is not limited to this particular construction, however, as it might be applied to other receptacles and to receptacles for other purposes.
One object of the invention is to rovide 1 a receptacle and the process for ma ing it, in which the receptacle itself and a cover retaining flange of the receptacle are made in a single piece and preferably as part of a continuous step-b -step process.
Other objects will apgear from time to time in the specification an claims.
My invention is illustrated more or less diagrammatically in the accompanying drawin s, wherein ig. 1 is a transverse, cross section, showing the receptacle in one stage of the manufacture.
Fig. 2 is a similar view, showing the receptacle as further processed.
Fig. 3 is a similar view, showing the receptacle in its final form.
Like parts are designated by like characters throughout the figures.
The receptacle is designated generally by the letter A. As shown, it is flared at its sides as at A into the general sha of a barrel. It is provided preferably wit laterally extended portions A which simulate in appearance the hoops of a barrel. The closed end of the receptacle may be indented, as indicated generally at A.
The receptacle, in its neral form, may be made in the manner escribed in Patent No. 1,647,547, or it may be produced in any other suitable way. v
The receptacle is, however, always to be made of a slngle blank. This blank will normallybe fiat to begin with and usually circular in outline. A generally hollow or cup-shaped form will be given to it and it may or may not be given the outer bul' ed barrel shape, as indicated in Fig. 1. and however it is made, there will be left an upwardly extending part which extends upwardly beyond a point which, in the finatever form it takesished receptacle, will define the top of the receptacle. It is one of the important features of the present invention to deal with this upward extension and to form from it the termination of the upper end of the recep- 6i tacle about its open mouth and also to form from it a flange adapted to position and to be used to seat and to fasten, a closure in the open end of the receptacle.
As shown in Figure 1, the process of manufacture has been partially completed so that the barrel with its hoops and indented bottom has been formed. A portion of the blank from whlch the barrel was originally drawn is left extending upwardl as designated by the letter B, as shown in ig. 1. In the ordmar manufacturing process the upper edge of thlsportlon B will be rou h and uneven and as shown in Fig. 1 it has en smoothed o5 trimmed so as to provide an even upper e e.
s shown in Fig. 2 the next step in completing the form shown in Fig. 1 has been taken. The upwardly extending part B has been partially pressed inwardly to produce the inwardly extending shoulder B and beyond this shoulder B the upper edge portion has been upwardl pressed again as at B.
As shown in ig. 3, the manufacturing process has been completed. The upwardl extending edge portion B has been struck downwardly. As this takes place, bending occurs generally in the shoulder B 'with the result that almost the entire part B is displaced downwardly and finally assumes the position of an inwardly extending flan e. In this operation the material generafiy designated as the shoulder B is stretched and bent and the portion B 'of Fig. 2 is deformed as it is forced downwardly so that the relatively narrow flange 13 remains; extending inwardly.' Any suitable closure may then be seated in the open end. It may rest on the flange B and may engage the under side of 'the flan e so as to be held in engagement within t e open end of the receptacle to prevent accidental or unauthorized displacement or removal.-
Although I have shown an operative device and a successful process for making the same,
it will be obvious that many changes in the size and arrangement ofthe parts and in the details of the process of making the device might be developed without departing from the spirit of my invention.
I claim:
1. A process of forming a unitary receptacle which includes the following steps: shaping a single blank to provide a hollow member having an open top and provided with an upward extension, pressing inwardly a portion of said upward extension, where y there are formed an inwardly extending shoulder and an upwardly extending portion, and subsequently exerting a pressure on said upward extension, forcing the same downwardly to provide an inwardly facing, annular flange positioned below said shoulder.
2. A process of forming a unitary receptacle which includes the following steps: shaping a single blank to provide a hollow member having an open top and provided With an upward extension of lesser diameter than the major portion of the main body, pressing inwardly a portion of said upward extension, whereby there are formed an inwardly extending shoulder and an upwardly extending portion, and subsequently exerting a pressure on said upwardextension, forcing the same downwardly to provide an inwardly facing, annular flange positioned below said shoulder.
3. A process of forming a unitary receptacle which includes the following steps: shaping a single blank to provide a hollow member having an open top and provided with an upward extension, pressing inwardly a portion of said upward extension, whereby there are formed an inwardly extending shoulder and an upwardly extending portion, of less diameter and shorter than said first mentioned upward extension, and subsequently exerting a ressure on said reduced upward extension, orcing the same downwardly to provide an inwardly facing, annular flange positioned below said shoulder.
4. A process of forming a unitary receptacle which includes the following steps: shaping a single blank to provide ahollow member having an open top and provided with an upward extension, pressing inward- 1y a ortion of said upward extension, whereby there are formed an inwardly extending shoulder and an upwardly extending portion of less diameter and shorter than said first mentioned upward extension, and subsequently exerting a pressure on said reduced upward extension, forcing the same downwardly to provide an inwardly facing, annular flange, positioned below said shoulder and having the same general diameter as the said reduced upwardly extending portion.
5. A process of forming a unitary receptacle which includes the following steps: shaping a single blank to provide a hollow member having an open top and provided with an upward extension of lesser diameter than the major portion of the main body, pressing inwardly a portion of said upward extension, whereby there are formed an inwardly extending shoulder and simultaneously an upwardly extending portion of less diameter and shorter than said first mentioned upward extension, and subsequently exerting a pressure on said reduced upward extension, forcing the same downwardly to provide an inwardly facing, annular flange, positioned below said shoulder and having the same general diameter as the said reduced upwardly extending portion.
6. The process of forming a complete unitary receptacle, which includes forming a single blank into a hollow, open ended member having anupwardly extending portion, treating said upwardly extending portion to force a part intermediate its ends inwardly to form an inwardly extending shoulder and retaining a portion of said upwardly extending part in the upwardly extended position, subsequently exerting pressure upon said upwardly extending portion to force thesame downwardly and to form it into an inwardly extended, annular flange within said receptacle.
7. The process of forming a complete unitary receptacle, which includes forming a single blank into a hollow, open ended member having an upwardly extending portion, treating said upwardly extending portion to force a part intermediate its ends inwardly to form an inwardly extending shoulder and retaining a portion of said upwardly extending part in the upwardly extended position, and causing it to remain as an upwardly extending portion of reduced diameter and length, subsequently exerting pressure upon said upwardly extending portion to force the same downwardly and to form it into an inwardly extended, annular flange within said receptacle.
8. The process of forming a complete unitary receptacle, which includes forming a single blank into a hollow, open ended member having an upwardly extending portion, treating said upwardly extending portion to force a part intermediate its ends inwardly to form an inwardly extending shoulder and retaining a portion of said upwardly extending part in the upwardly extended position, subsequently exerting pressure upon said upwardly extending portion to force the same dow nwardly below the said shoulder and to form it into an inwardly extended, annular flange within said receptacle.
9. The process of forming a complete unitary receptacle, which includes forming a single blank into a hollow, open ended member having an upwardly extending portion, treating said upwardly extending portion to force a part intermediate its ends inwardly shoulder and to form 1t into an inwardly extended, annular flange within said receptacle. v
