Description

Container Body With Two Shoulders The present invention concerns a container body for a non-round container having a lid beaded onto the upper edge, the side wall of which is provided with a shoulder.

Unstackable container bodies have been known for a long time.
Thus, a cellulose container is disclosed in US 3,233,812 which can be stacked and whose side wall has a supporting shoulder in the corner areas.

US 4,366,696 shows a conical can body with a peripheral profile having three bends whereby, seen from the bottom to the top, the first bend with a first radius of the side wall (seen in cross-section) gives a convex shape and the second bend with a second radius gives it a concave shape. A third bend leads the side wall outward again in a convex manner, whereby the radius of this last bend is substantially greater than that of the other two. As a result, according to the patent, a profile is produced which shows a smooth surface and which can be easily unstacked, whereby the stacked cans have a selected distance from one another.

US 4,366,696 mentions that two-piece cans with an integral bottom and side wall represent a preferred construction since they solve problems relating to leakages of the beaded edge.
However, the can shown there has the disadvantage that, when the shoulder formed by the noted bends is just below the upper end of the side edge, the stack becomes too compact, so that there are problems during unstacking (such as jamming and the like) while, when the shoulder is lower, the stability is not sufficient during beading, so that defective beaded edges can result.
It is the object of the present invention to create a container body for a non-round container which is easily stackable and unstackable on the one side, yet also has a shape on the other side which makes it especially suitable for beading on a lid because the beaded cover is good.

Surprisingly, it could be found that such container bodies exhibit both an easy unstackability and also a good stability when the lid is beaded on, the side wall of which is provided with a shoulder consisting of a first shoulder and a second shoulder, whereby the first shoulder is bent less sharply in at least a part of those areas which are, viewed from the top, elongated or less bent when compared to other parts, is arranged closer to the upper edge of the container than the second shoulder in the remaining areas and whereby the side wall, at least in parts of the areas in which the first shoulder is present, has lateral riffles, when viewed from the side, said riffles extending essentially vertically above the level at which the second shoulder is located. The run of the lateral riffles up to above the level of the second shoulder results in an extremely good wall rigidity, so that the force of the beading tools transmitted to the side wall during beading do not lead to its deformation.

The running of the f irst shoulder into the second shoulder may be designed as desired. Thus, for example, the first shoulder can be led in a curved manner to the second shoulder.

-2a-According to an aspect of the invention there is provided a metallic container body for a non-circular container having curvatures, with a flanged lid on the upper edge, whose side wall has two shoulders, wherein a first shoulder in at least a part of first side wall areas, which seen in plan view are elongated or in comparison to other segments, are less strongly curved, is arranged closer to the upper edge of the container than a second shoulder in the second side wall areas, and wherein the side wall at least in partial segments of the first side wall areas, in which the first shoulder is present, has side flutes as seen in the side elevation running substantially vertically, and wherein the side flutes extend up above the height at which the second shoulder is arranged.

The invention shall be described in greater detail in the following with reference to exemplary drawings.

Figure 1 shows a part of a container body according to the invention in a side view. The bottom surface 5 goes over in one piece into a slightly outwardly inclined side wall 2. The first shoulder la is situated in the left part of the Figure which shows, seen in the top view, a straight or only slightly bent part of the container, while the second shoulder lb can be seen in the right part (more sharply bent, seen from the top), said second shoulder extending less closely to the upper edge 3 of the container than the first shoulder. Not quite up to the end of the area with shoulder la, an area with lateral riffles 4 extends which end above the level of the shoulder lb. The side wall has, above the level of the second shoulder lb, sections 2a, 2b, 2c, whereby the upper sections 2a, 2b above the shoulders la, lb are slanted outward less sharply than the remaining part of the shoulder 2. The transition 8 between the two shoulders la, lb extends in a small curve.

Figure 2 represents an enlarged section from Figure 1 which shows a lateral riffle 4. 7 designates the edge which is formed by an obtuse angle deviating only slightly from 1800 in the side wall 2.

Figure 3 shows side edges 2 of two container bodies 6, 6' according to Figure 1, stacked into one another. A
side edge of each of the two container bodies 6, 6' is shown, each having a first shoulder la and one having a second shoulder lb placed above one another. In this case, the side edge with the shoulder la appears as a solid black stroke, while shoulder lb is shown as an unfilled stroke. It can also be seen here that, in this embodiment, the ,..
upper sections 2a, 2b and 2c of the side wall 2 have an identical slope and are slanted outward a little less than the lower part of the side wall 2.
Furthermore, the geometry of a lateral riffle 4 can also be seen, the run of which begins above the shoulder lb in this embodiment and ends in the middle between the levels of the two shoulders.
Figures 4 to 6 show further embodiments of the container body which only differ from those shown in Figures 1 to 3 by the shape and height of the run of the riffle 4.

The invention is suitable for all container bodies which in plan show at least one curvature, provided that there is no exact circular shape. In particular, these include oval or rounded container bodies elongated in another shape, such as those for fish cans, but also those which have more or less sharply rounded corners.

The container bodies may be made of any material desired, provided that it is suitable for being beaded together with a lid. These include, for example, all types of sheet metal or coated metals, but also plastics or ma~erials made of natural substances, perhaps appropriately modified, or materials which have been treated or coated on the surface.

The bottom of the container body according to the invention can be designed as desired, depending on the requirement, e.g.
it can be flat or also be curved inward or outward. The bottom passes over into the side wall, whereby the two aforementioned parts may be in one piece or joined by beaded or welded seams or otherwise from several parts. The side wall can extend upward at right angles or be more or less sharply slanted outward.

Due to the shape of the container body, it has areas, seen in a top view, which are more sharply bent, as well as areas which are less sharply bent or elongated. An oval, conventional fish is, for example, more sharply bent at the tear-open area and at the opposite side than in the areas lying in between which, for the most part, are straight in parts. A four-sided can with rounded corners has four sharply bent areas while the areas in between are straight. The container body according to the invention has a first shoulder, in at least one part of the noted straight or less sharply bent areas, said first shoulder being relatively close to the upper edge of the container. A second shoulder, which can be used as a supporting shoulder for stacking and unstacking, extends in the more sharply bent areas. The first shoulder can, for example, be spaced from the upper edge of the container which is between 30% and 50% of the distance of the second shoulder from the upper edge. Of course, other dimensions are also possible, depending on the requirement.
At least in parts of the areas in which the first shoulder is present, the side wall additionally has a riffle. In the side view, this riffle extends essentially at right angles and follows the slope of the wall. The lateral riffles extend over the level at which the second shoulder is situated and preferably ends about halfway up between the two shoulder levels or in the level of the upper, first shoulder. By raising the lateral riffles above the level of the second shoulder, an improved wall stability results, so that it is ensured during the interaction with the first shoulder, arranged just below the upper edge in the elongated or less sharply bent areas, that, when beading the lid on, the cover of the two parts is better and more secure than with previously known container bodies.

In a preferred embodiment, at least one of the two shoulders is formed in such a way that the side wall, seen in cross-section and from top to bottom, first extends outward in an arc-like manner and then inward in an arc-like manner. The two radii used thereby can be identical or different. In a special embodiment, the first arc-like segment with which the side wall is led outward describes a smaller arc-like section than the second segment. As a result, the side wall above the shoulder has a slighter slope outward than the side wall below the shoulder. If the lower part of the side wall is slanted outward only very slightly, the aforementioned part of the side wall which is above the shoulders may then also be made e.g. at right angles to the bottom surface.

The embodiment of the arcs described above are especially suitable for the second shoulder. It is especially preferred that the side wall, seen from the top, in the elongated or less sharply bent areas compared to other parts, is at the level of the second shoulder and is bent inward obtusely with an angle which is only a little less than 180 . It is especially preferred that the selection of the radii and the length of the arc-like sections of the second shoulder and the selection of the obtuse angle present at the level of this shoulder are coordinated to one another in the areas in which the second shoulder is not present, in such a way that the side wall has, at the level between the first and the second shoulder, a constant angle to the lower area of the side wall or to the bottom surface, irrespective thereof whether the can, in a top view, is bent sharply, less sharply or not at all.

The preceding embodiments are, of course, made without inclusion of the lateral riffles. It is clear that the geometry changes at those points at which the side wall rebounds inward due to the presence of a riffle.

The lateral riffles provided according to the invention may have any shape desired, viewed from the top. They may, for example, have a bent, round, oval, triangular, trapezoidal or polygonal contour.
