Description
FLEXIBLE BOTTOM PROFILE FOR
DRAWN AND IRONED BEVERAGE CAN
This invention relates to a can with a dome-shaped (calotte) bottom outwardly or inwardly offset center portion circumscribed by an annular bead between the dome and the can body.
Cans in one piece of a similar kind are known as disclosed in U.S. patents 3,369,694, 3,904,069 and 3,409,167 which show various types of expandable bottoms. The disad-vantages or problems in these known cans are that:
a. The application of the profiles disclosed leadto a considerable difference in height between the closed and the empty can, on the one hand, and the conventional can with a large rigid calotte (cup) on the other. This has as a con-sequence costly conveyor changes in the installations at thecustomer.
b. Furthermore, in the conventional can with the large, rigid calotte, it is known that the adhesion of lac-quer or coating on the interior is worse where the slightest deformation of the sheet metal takes place, namely in the area of the bottom profile. Such profiles as dlsclosed in the above references are submitted to a lesser deformation than that of the instant invention.
c. When the containers with the prior art profiles are pressurized rolling out of the ends which delimits the small calotte from the flat portion can occur. The thereby caused embrittlement of the lacquer may cause a premature defect of the can.
d. The relative afterflow of the sheet material from the body into the area of the bottom is greater in the disclosed profiles than in case of the conventional large rigid calotte.
e. The resulting value of the unit pressure upon the small calotte is smaller in case of the known profile than the pressure upon the conventional calotte, but thç
sheet metal in the area of the smaller inner calotte is un-necessarily thick.

DRAWN AND IRONED BEVERAGE CAN
This invention relates to a can with a dome-shaped (calotte) bottom outwardly or inwardly offset center portion circumscribed by an annular bead between the dome and the can body.
Cans in one piece of a similar kind are known as disclosed in U.S. patents 3,369,694, 3,904,069 and 3,409,167 which show various types of expandable bottoms. The disad-vantages or problems in these known cans are that:

d. The relative afterflow of the sheet material from the body into the area of the bottom is greater in the disclosed profiles than in case of the conventional large rigid calotte.
e. The resulting value of the unit pressure upon the small calotte is smaller in case of the known profile than the pressure upon the conventional calotte, but thç
sheet metal in the area of the smaller inner calotte is un-necessarily thick.

-2- ~ 7 These problems are solved by the features of the preserlt invention. In case of cold~drawn cans it is caused by deformations in the annular bottom area that in stretch-drawing and in forming the bottom deformations less of the material flows from the body area into the bottom area and the calotte-shaped section is equally stretch-drawn by a reduction of the thickness of its sheet metal, while in the known cans only a deformation of the area of the calotte is basically obtained. By the greater stretching of the area of the calotte, a considerably better adhesion of the lacquer layers on the inner surface of the can is obtained in the bottom area because of the greater roughness caused by the stretching operation and the larger area thereof.
A to-the-outside circular, or even better an in-ward projecting bead in the bottom section has proven to beadvantageous. This bead borders advantageously directly with the edge of the calotte. The bead needs to project only qlightly from the plane, in which the outer edge of the an-nular bottom section is placed, to the outside or to the in-side. ~ height of the bead of less than 2 mm, preferably aheight between 0.2 and 0.5 mm suffices. In the latter case, the stability of the empty can above all is also improved.
In a crown-shaped arrangement of several deforma-tions in the annular bottom section these deformations pro-ject throughout into the inside of the body of the can. Thedeformations can then penetrate at least into the inner delimiting edge of the annular bottom section, so that they penetrate slightly even into the calotte area.
This invention relates to the provision of a metal can for pressurized packaged products, the can in an as formed non-pressurized state comprising a cylindrical body and an in-tegral bottom, the bottom including an outer transition sec-tion of inverted frustoconical shape joined to the body by a radius, a generally planar intermediate ring-shaped section, and a central calotte-shaped section pro3ecting into the in-terior of the can, the can bottom being characterized by stif-fening deformation means in the intermediate ring-shaped section.

It has also proven to be of further advantage to provide several blank (cup) like impressions dividedly ar-ranged in the annular bottom section on two concentric par-tial circles.
The invention is best explained on several ex-amples of embodiments with the aid of schematic drawings wherein:
Figure 1 is a vertical sectional view of the lower portion of a can made according to the invention;
Figure 2 is a fragmentary bottom view of the can shown in Figure l;
Figures 3, 5, 6, 7, 8, 10, 12, 14 and 16 are fragmentary schematic vertical sectional views of various embodiments of the invention, and Figures 4, 9, 11, 13, 15, and 17 are fragmentary bottom views of the cans of Figures

3, 8, 10, 12, 14 and 16, respectively.
The can shown in Figures 1 and 2 has a basically cylindrical can body 1 which at its lower end is integral -with a bottom. The transition between the body and the bottom can be made by a rounding or curve, preferably, how-ever, by a beveling in the shape of a truncated cone 3, as shown in Figure 1. The bottom proper consists of two sec-tions, namely of a central section 6 projecting into the `
inside of the body 1 and being of ~alotte or dome shape, and surrounding the central section 6 is an intermediate bottom section 5 that is basically radially extending. The radial W~dth of the annular section 5 of the bottom 2 is radially li~ited ~t the in$ide by the edge 8 to the calotte shaped portion 6 and at the outside by ~he edge 4 of the transition-al sec~ion 3, The calotte 6 is visibly thinner than theannula~ bottom section 5.
As far as heretofore described, the design of the bottom corresponds basically to the design of the bottom of the container according to Figure 5 of ~.S. patent No.

While in the heretofore described examples of embodi-ments the deformations are made annularly, it is equally feasible to make crown-shaped divided deformations in the annular bottom section 5.
In the example of embodiment according to Figure
7, radially extending depressions 27 are provided which extend between the edge 13 of the dome 6 and the edge 13 and the edge 14 and of the truncated portion 3. The depres-sions widthwise (circumferentially of the can) are of the order of those shown at 30 in ~igure 11.
In the example of embodiment according to Figures
In the example of embodiment according to Figures
8 and 9, there are at least four circumferentially spaced, equally cup-shaped depressions or dimples 28 provided in the bottom section 5. The depressions extend into the interior of the body of the can. The dimples 28 intersect the radi-ally inner limiting edge of the annular bottom section 5 as clearly shown in Figures 8 and 9. Instead of four, a greater number of cup-shaped deformations can be provided as indicated in dash lines at 28a.
In the example of embodiment according to Figures 10 and 11, the cup-shaped depressions of the embodiment of Figures 8 and 9 are elongated in a radial direction to extend over the entire width of the annular section 5 so that the outside placed ends of the depressions 30 or 30a penetrate into the frustoconical transitional section 3.
In the example of Figures 12 and 13, there are cup-shaped depressions 35 which have a basically radial extent approximately equal to the radial width of the annular sec- -tion 5.
