Definitions

• the present invention relates to a container body for a non-round container with a lid crimped on the upper edge, the side wall of which is provided with a shoulder.
• Unstackable container bodies have been known for a long time.
• US Pat. No. 3,233,812 discloses a cellulose container which can be stacked and whose side wall has a support shoulder in the corner regions.
• No. 4,366,696 shows a conical box body with an edge profile with three curvatures, the first curvature with a first radius of the side wall (seen in cross section) giving a convex shape from bottom to top and the second
• Curvature with a second radius gives it a concave shape.
• a third curvature leads the side wall convexly outwards again, the radius of this last curvature being substantially larger than that of the other two. According to the patent, this creates a profile that has a smooth surface and is easy to unstack, the stacked cans being at a selected distance from one another.
• US 4,366,696 mentions that two-piece cans with integral bottom and side wall are a preferred design because they solve problems with flared edge leaks.
• the mandrel shown can has the disadvantage that when the shoulder formed by the said curvatures is relatively just below the upper end of the side edge, the stacking becomes too dense, so that problems with unstacking (such as jamming and the like) arise , while if the shoulder is lower, the stability during the flanging is not sufficient, so that faulty flanging edges can arise.
• the object of the present invention is to provide a container body for non-round containers, which is stackable and unstackable on one side, but also has a shape on the other side that makes it particularly well suited for flanging a lid because the flare coverage is good.
• Sidewall is provided with a shoulder of a first and a second shoulder, the first shoulder being arranged closer to the upper edge of the container in at least a part of those regions which, when viewed from above, are elongated or less curved than other partial regions than the second shoulder in the remaining areas, the first shoulder and the second shoulder being formed in that the side wall, viewed in cross section and indicated from the bottom upwards, is first guided outwards in a circular arc and then inwards in a circular arc.
• the aforementioned arrangement and shape of the shoulder ensures that the rigidity is sufficiently high even in the container areas that are straight or slightly curved in the view, so that the force of the flanging tools transmitted to the wall does not lead to their deformation during flanging.
• the opening of the first into the second shoulder can be designed in any way.
• the first shoulder can be arched to the second shoulder.
• Figure 1 shows side edges 2,2 'of two stacked container bodies 6,6'. From each of the two
• Container body 6, 6 ' shows a side edge with a first shoulder 1 a and one with a second shoulder 1 b superimposed.
• the side edge with the shoulder la appears as a solid black bar, while the shoulder lb is shown as an unfilled bar. It can be clearly seen that both the shoulder la and the shoulder lb are formed in that the side wall, indicated from bottom to top, is first guided outward in a circular arc and then inward in a circular arc.
• the geometry of a side reef ice 4, which ends below the shoulder 1b, can also be seen.
• FIG. 2 shows a part of a container body according to FIG. 1 in a side view.
• the bottom surface 5 merges in one piece into a slightly outwardly inclined side wall 2.
• the first shoulder 1 a is arranged, while the right shoulder (more curved in the view) shows the second shoulder 1 b, which is less close to the top edge 3 of the container runs as the first shoulder.
• the side wall has lb above the height of the second shoulder
• An area does not extend all the way to the end of the area with the shoulder la
• FIG. 3 shows an enlarged section from FIG. 2, which shows a side corrugation 4. 7 denotes the edge which is formed by an obtuse angle in the side wall 2 which differs only slightly from 180 °.
• Figures 4 to 6 show an embodiment that is identical except for the shape and height of the outlet of the corrugation 4.
• Figures 7 and 9 show a further embodiment in which the side ridges 4 are guided to just below the height of the shoulder la.
• FIG. 8 shows an embodiment in which the corrugations 4 run out at the shoulder la.
• the invention is suitable for all container bodies which have at least one curvature when viewed from above, provided that there is no exact circular shape.
• this includes oval or other elongated, rounded container bodies, such as those for fish cans, but also those which have more or less rounded corners.
• the container body can be made of any material provided that it is suitable for crimping with a lid. This includes, for example, all types of sheet metal or coated metals, but also plastics or materials made from natural materials, which may be modified or processed or coated on the surface.
• the bottom of the container body according to the invention can be designed as required, z. B. it can be flat or also have bulges or bulges.
• the floor merges into the side wall, and the two parts mentioned can be in one piece or can be connected by flared or welded seams or otherwise made up of several parts.
• the side wall can run vertically upwards or be more or less inclined outwards.
• the container body when viewed from above, it has seen areas that are more curved and areas that are less curved or elongated. For example, an oval, conventional fish can is more curved on the tear-open area and on the opposite side than in the areas in between, which are mostly straight.
• a four-sided box with rounded corners has four strongly curved areas, while the areas in between are straight.
• the container body according to the invention has a first shoulder in at least part of the said straight or less strongly curved regions, which is arranged relatively close to the upper edge of the container.
• a second shoulder runs in the more curved areas and can serve as a support shoulder for stacking and unstacking.
• the first shoulder can be arranged, for example, at a distance from the upper edge of the container that is between 30% and 50% of the distance of the second shoulder from the upper edge.
• other dimensions are also possible depending on requirements.
• the side wall preferably has additional corrugation at least in partial areas of the areas in which the first shoulder is present.
• This reef formation should run essentially vertically in the side view and follow the slope of the wall.
• the side corrugations can have any shape when viewed from above. For example, they can have a curved, round, oval, triangular, trapezoidal or polygonal contour.
• the side corrugations can run out at the level of the second shoulder, but they preferably run at about half the height between the two shoulder heights or at the level of the upper, first shoulder.
• the two shoulders are formed in that the side wall, viewed in cross section and indicated from top to bottom, is first guided outwards in a circular arc and then inwards in a circular arc.
• the two radii used can be identical or different.
• the first circular arc segment, with which the side wall is guided to the outside describes a smaller keisbogen section than the second segment.
• the sidewall above the shoulder is less inclined outward than the sidewall below the shoulder. If the lower part of the side wall is only slightly inclined outwards, the mentioned part of the side wall, which is located above the shoulders, can then e.g. also be formed perpendicular to the floor surface.
• the side wall in the elongated areas seen in the top view or, in comparison to other partial areas, less curved areas at the height of the second shoulder is angled inward at an angle that is only a little less than 180 °. It is very particularly preferred that the two radii and the length of the circular arc sections of the second shoulder and the choice of the obtuse angle present at the level of this shoulder in the areas in which the second shoulder is not present are matched to one another such that the side wall at the height between the first and the second shoulder has a constant angle to the lower region of the side wall or to the floor surface, regardless of whether seen from above, the can is stronger, less strong or not curved at all at this point.
