Container, especially can *

The fire affects a container, in particular a can, consisting of a body made of - compared to the cover sheet, very thin and relatively brittle sheet metal and a sheet metal cover made of thicker and possibly more ductile sheet metal with a cover core engaging in the open sump end and a with this Palz track connected via a folded track radius, whose sand is reinforced by laying it down. ■ \

A metal container is known whose body and cover or base are connected by means of a folded seam which has one of the folded tape of the closure part has reinforced shoulder. A sealing connection between the lid and the body is only here by the simultaneous deformation of Palzbahn, Eumpfende and lid core received, so by measures such as they are also present with the usual double-fold seam and -i-n * determined the cases explained in more detail below should be avoided! have to.

Another metal container has a plug-in cap, which has an outward-pointing shoulder or bead, which is an inwardly open shoulder or bead © of the edge of the trunk opposite and serves together with this to accommodate a thick, squeezed-in sealing ring.

Finally, it is also known, in metal containers pinch the hand of the cylindrical body between the core and the Falzbahn the lid over a greater axial length and a shoulder-like bend to go halfway up the Einklemmstrecke the parts to a positive lock between the! Parts to guarantee. It is essential that the beaded edge of the folded sheet is partially pressed into the wall of the 3? Reduction of the thickness of these two wall areas. This known arrangement assumes that the cover and body are made of relatively easily deformable material.

The! Inflation is based on the task of a container of the To create the type mentioned at the beginning, in which a secure and direct connection between the body and cover is then also made possible when the body is made of a very thin material of low deformability compared to the cover, which is necessary for the Production of the otherwise usual double-fold seam is not sufficient. This object is achieved according to the invention in that the fuselage

- "5

consists of a - compared to the lid - very thin and relatively brittle sheet metal, and the end of the fuselage over a radius in. an inwardly drawn in, approximately horizontally extending shoulder passes over and has an axial length corresponding to the height of the cover core, and that the axial length of the pallet sheet is so much greater than the height of the cover core that its reinforced edge is below that from the inside through the cover core and the core radius supported torso shoulder is retractable. With this design, the core radius of the lid rests firmly on the shoulder of the end of the fuselage, while the core wall rests against the fuselage wall over its entire height. As a result, the fuselage wall is securely supported at all points when the seam is formed, so that it is not subject to any deformation or change in thickness. At the same time, however, the reinforced edge of the Palz web can be pulled firmly and completely under the supported torso shoulder. In doing so, is the radius of the folding path pulled firmly over the ron metal edge of the hump _? so that tin® auig © - = · marked seal is achieved.

It has surprisingly been found that in this embodiment a fixed Iaht can be achieved, even if the cover plate is substantially thicker than the fuselage sheet, which is very thin * preferably only about 0.1 - O ₉ can 28 be thick, without at. the risk of being subject to significant stress or deformation, which is of particular importance because the thin hull material is usually relatively brittle.

With the new arrangement, it is practically made possible, a lot to use thin, brittle metal sheets for can production, the use of which has hitherto generally failed because this Tear or break sheet metal when flanging and too ündichtig- ^ lead.

Advantageously, the design is made so that the trunk immediately adjoins the trunk shoulder in a transition section which gradually widens outwards to the normal trunk diameter, which is also the maximum diameter of the closed container ₉ so that no rope is radially outward protrudes outside the outer diameter of the fuselage «

The furnace is explained in more detail below using schematic drawings of several exemplary embodiments *

In the embodiment of the invention disclosed herein, the improved closures (lids or bottoms) are on a can body provided, which can best be seen in FIGS. 1 and 2, in which the cover and base are designated by 6 and 7 are. At each end of the fuselage, a generally cylindrical part 8 is provided with an end edge 9 which extends upwards or is directed downwards. Each generally cylindrical part 8 goes over a radius 10 into a horizontal one Seat or locking shoulder 11 over, and each horizontal seat or shoulder goes through one inward, downward and then outwardly curved part 12 in an outwardly curved trunk extension 13, which in turn at 14 in the Main body part 5 passes. Between the outwardly curved Extensions 13, the main hull is evenly corrugated on its circumference, so that the very thin wall of 0.004 to 0.011 "

The in the embodiment "example of the invention according to Pig" 2 to 5 The ends or lids shown are shown in FIG. 6 in a nested, stacked arrangement. Each such Can end piece or such a closure has a middle lid base 16 and a surrounding this and after at the bottom opening edge part 17. The edge portion includes a Lid core 18, which over the core radius 19 in the lid base

16 and over the folding path radius 20 into the folding path or the seam edge 21 skips “The folded web or seam edge 21 is longer than the lid core is high and is bent inwards at its extension beyond the lid core depth Edge (hook) 22 provided. It can be seen from FIGS. 2 and 6 that each can closure part (lid or base) is also equipped with a sealing compound 23 or a connecting adhesive compound.

The steps in forming the closure are shown progressively in Figures 2-5. From Figure 2 it can be seen that the lower extreme end of the can body 5 is supported and held at 24 on the base plate 25, and the lid

17 is placed in the figure mentioned as being placed on the upper extreme end of the trunk and on the horizontal shoulder 11 at 26 shown dormant. The base plate 25 and a clamping head 27 are then moved relative to one another in such a way that the clamping head base 28 against the lid base 16 and the radius 29 of the head against the

/ Cover core 18 to rest of the can end is _s as shown in Fig. 3 _o By so placierten clamping head, a closing roller 30, which is at 31 with the chuck 27 engaged in known manner in contact with the Falzbahn or the seam edge 21 of the can end, said roller having the usual pressing surface or forming surface 32 and a part 33 that forms and fixes the can seam in the area of the lid hook the folded web 21 and the cylindrical body wall part in the manner clearly shown in Pig »3. The part 33 of the sealing roller which deforms and fixes the folding path is designed so that it becomes effective during the rolling of the seam through the sealing roller in order to first bring the folded edge 22 into connection with the radius 10 at 34 and the edge at 35 to bend inside, then continuously deform the edge and fit it under the horizontal shoulder 9 and fix it, as shown in Figo. During the deformation and fixing of the edge reinforcing the cover, as described and shown continuously in FIGS. 3 and 4, the cover fold is pulled down in order to press the core radius 19 firmly against the horizontal shoulder, the fold path or edge 21 after to pull down and stretch the same over the outermost end 9 of the can body wall 8 (Fig. 3) and hold!

From FIG. 4 it can be seen that not only the folded edge 22 reinforcing the can end or the lid is below the radius

10 and the horizontal shoulder 9 fitted and securely set is, but that the rough metal edge of the edge 22 is included in the seam that it does not come into contact with the closure elements is housed protected. In the method described for forming the seam, the sealant or the connecting means 23 in the seam in the Fig. 3 and 4 distributed manner shown and serves to seal the seam when sealants are used alone or to create a connection and sealing of the seam parts if a connecting sealant is used »

In the embodiment shown in FIGS. 7 to 10 Invention are can ends or lids, which are shown again in FIG. given type. These can ends are similar to the lids previously described with the exception that they are at the bottom and outwardly widened outermost parts of the edge opening downwards with a curvature bent outwards and upwards 37 instead of the inwardly curved folding edge, as shown in FIG. 6. In other words each of these modified can ends includes a bottom portion 38 which is separated from a downwardly opening edge portion surrounding it 39, this edge part enclosing a cover core 40 which extends into the cover base 38 via a cover radius 41 and over a folding path radius 42 into a folding path or a Edge 43 passes, which, as in the previous form, is longer than the folding web height and at its outermost end or the Extension beyond the tensioning track is provided with the aforementioned curl 37. As shown in Fig. 7,

a sealing compound or an adhesive 44 is preferably introduced into the folded path radius.

These modified forms of can ends or lids are applied to can bodies that are constructed with the previously described are the same. Each includes a generally cylindrical wall portion 45 at each extreme end with an end edge 46, and each generally cylindrical portion 45 passes over a radius 47 in a horizontal seat or a torso shoulder 48 and each shoulder 48 over one part bent inwards, downwards and then outwards

49 into the corresponding outwardly curved trunk extension

50 over, which in turn in the corrugated main body part passes as previously described.

Referring to Figures 7 through 9, the sequential steps for formation the seam shown, and it is understood that the lower outermost part of the can body in the above-described Manner is supported and fixed, as shown in FIG.

In Fig. 7 the can end is on top of the top of the can body and shown resting on the seat or horizontal shoulder at 51. The clamping head 52 is now in brought into contact with its base 53 with the lid base 38 in the manner described above, FIG. 8 and the radius 54 of the head pressed against the cover core 40. The locking roller that cooperates with and engages with the clamping head 55 has a shaping pressing surface 56, which is

is how it is necessary to carry out the continuous deformation of the folded web, its outermost end and its curl 37, as can be seen in FIGS. 8 and 9. The initial deformation of the curl is at 57 in I ¹ Ig ₀ 8 and the completed deformation of the curl into the shape of an outwardly curved reinforcing edge and the deforming and laying of the seam under the horizontal corrugated shoulder 48 is shown at 58 in Pig »9»

It goes without saying that in both embodiments of the invention disclosed herein, namely those in FIGS 5 and the shapes shown in Pig, 7 to 9, deformation and fixing the reinforcement edge under the horizontal shoulder 9 or 48 serves to keep the folding web down to pull the core radius 19 or 41 firmly against the horizontal shoulder and the folding path radius 20 or 42 firmly against the to press the outermost end of the can body, with the folding track 21 or 43 of the sealing seam by setting the reinforcement edge is held in tension under the horizontal shoulder of the can body in the manner indicated «

The new can body, closure, and method of manufacture have yielded notable advantages of which some can be enumerated here.

The use of the flangeless hull construction, in particular without an overlapped side seam offers great metal savings.

The particular shape of the fuselage with its flangeless and generally cylindrical part 8 or 45 and the indentation

12 or 49 facilitates the introduction of the filling and prevents parts of the filling from penetrating the mowing, as a result of which faulty seams can arise »The smoothly rolled, rolled indentation facilitates the entry of the filling, and the raw metal edge at the extreme end of the fuselage cuts through the filling when the closure is thrown open, if this stretched over the edge

The special shape of the seam leads to a secure seal and strength of the seam without the need to roll flanges together. From FIG. 1 it can be seen that the seams Shaped and arranged in such a way that there is no protrusion beyond the diameter of the trunk »This arrangement enables a more solid Storage and wrapping and less damage to the closures due to seam on seam »

The special seam designs with reinforced edges also provide safe shoulder parts against which opening devices, either of the rotating, articulated and piercing types can be firmly applied «

The ends or closures of the type shown in FIGS _o 7 to 10, in a single operation using existing standard Verschließpressen by simple arrangement of the press tools for manufacturing the closures are produced in the reproduced in Figo 7 and 10 forms.

When producing the closures according to the shape shown in FIGS. 2 and 6, a first punching out of the

Closure part and in a second operation the bending of the edge to form the folded edge take place.

While preferred embodiments of the closure, the Hull and seam structures and the method of manufacture of the closure have been described in detail, it is understood that modifications of the constructions mentioned and the steps of said method can be carried out without departing from the invention set out in the claims.
