BLANK FOR FORMING MILK CANS Filed June 30, 1931 g l \g m //////////////7'77741/ ll/l/ [M Patented Oct. 17, 1933 BLANK 110B FORDIING MILK CANS Alfred Edmund Steinacher, Frauenfeld,
Switzerland Application June 30, 1931, Serial No. 548,006, and in Germany July 7, 1930 1 Claim. (Cl. 29148.2)
Applications have been filed in Germany July 7, 1830, and in Switzerland June 9, 1931.
It is known that milk transport cans are subiected to great external, mechanical forces. For this reason efforts have been made since a long time past to reinforce the wall, neck and foot parts of the same, particularly in the production of cans of light material, for example aluminium.
These reinforcements, particularly the foot reinforcements however only fulfil their purpose incompletely because they are riveted or soldered or sweated to the can bottom.
There are, for example, constructions in which the can is formedof two parts, that is to say, from a can body of rolled sheet metal formed by a longitudinal weld, and a foot body, these parts being attached together by welding, whereby the welded seam is situated in the can body at a suitable distance from the foot. The inside of the can therefore is neither smooth in the longitudinal direction nor in the lateral direction. Constructions are also known wherein a ring is laid round the wide part of the vessel and is soldered or welded or riveted to a foot ring provided thereover. Furthermore constructions are known in which there is a second bottom which is welded I everywhere beneath the bottom of the can in as air-tight a manner as possible.
All of these constructions are however unreliable, as for example the first named construction,
or are complicated and therefore costly and their results in use are not reliable. I M
The method and can according to'this invention are for the purpose of obviating the hereinbefore stated defects and the novelty lies therein that the blank employed to produce the whole transport can is provided with a foot ring in the production ofits initial form.
It is achieved thereby that a can produced from a blank has a foot ring which forms an integral inseparable piece of the other parts, without any soldered, welded or riveted seam and the strength of which is sumcient against all external influences. In addition, because the blank has a bottom hollow, the can is produced from a minimum quantity of material.
A constructional example of the invention is shown in the accompanying drawing, in which- Figures 1 and 2 show a blank, and
Figure 3 shows a complete milk can.
According to the said method, the blank shown in Figures 1 and 2 and intended for the production of the whole can, is already provided with a foot ring 3 in the creation of its initial form, the ring 3 having a bottom hollow 4, The blank in its initial form already possesses at least partly, thewall of'a complete can. The parts of the blank which lie outside the foot ring are then driven upwards, whereupon the can is worked from the upwardly bent material, Figure 3, whereto by a completely smooth inner surface of the can is obtained.
The blanks may be produced by casting or pressing and they may have a form which difiers somewhat from that shown in the drawing. 1 85 The milk transport can, Figure 3, produced by the hereinbefore described method has a wall 1,
a neck 2 and a foot ring 3 which is provided with a bottom hollow 4 and was already present in the blank, whereby the foot ring forms an integral, inseparable piece of the other parts of the complete milk can, without any welded, soldered, or riveted seam.
In the manufacture of this can, there is pl'ovided, by casting orsome type of forging or pressing, a circular blank having a circular central portion 4 of the same thickness and form as the bottom of the completed can. The outer portion of the blank forms an annulus 5. of sufiicient thickness to permit its being drawn to form the so side and neck portions of the can. A rib 3 is formed on this blank on the under side of the blank and at the periphery of the central portion 4. Y
The blank thus constituted is formed into the can by drawing the portion 5 upwardly by any suitable means such as are commonly employed for drawing hollow ware articles, the usual means being a set of successive drawing dies. The means employed is such as to leave a thick lower por tion 6 and a. corresponding'thick upper portion. '7, the side wall 8 between these portions being drawn out to form a thin wall. The shoulder portion 9 and neck 2 may also be formed by any usual means such as swaging dies.
It isto be unde'rstoodthat I make no claim to a specific mechanism for effecting the drawing operations as the same may be done by a wide variety of well known mechanisms.
Furthermore, other methods of forming the" can from the blank may be employed. For instance, the blank may be placed in a spinning lathe and the can formed by spinning over the usual collapsible mold or form.
My invention, however, does consist, in substance, in the peculiar blank arranged to form a foot ring and in forming, by whatever means are used, the side, shoulder and neck portions from the annular portion of the blank lying outside the preformed bottom and foot ring.
Having now particularly described and ascertom, said blank having a thick annular portion tained the nature of my said invention and in relatively thick with respect to the central porwhat manner the same is to be performed, I detion and surrounding said central portion; and clare that what I claim ls-- further having an annular flange constituting a 6 A blank for forming a milk transport can contoot ring on its under side at the periphery of 80 sisting of a disk of metal having a central portion the central portion. preformed to'the shape and sizeot the can bot- ALFRED S'IEINACHER,.
