Definitions

• the invention relates to a can body with a base and a peripheral side wall projecting therefrom and surrounding an interior.
• Can bodies are known in many forms. They pack very different foods and change the demands placed on them in terms of aesthetic appearance, durability, stability and stackability.
• a tin made of sheet metal which is circular in cross-section, the side walls of which expand upwards and which has a bottom which stands on the bottom by means of an annular adjusting part, while the central region of the The floor is curved upwards, i.e. does not touch the floor when parking.
• the side walls are curved.
• the stability of the can body is increased, because completely flat floors could warp and, in the event of production-related irregularities, also result in the canned body not standing on the floor in a defined manner, but instead, for example, only in a punctiform manner rests unstably on a more or less randomly lowest point on the floor and the entire can therefore tends to wobble.
• the control element that is the round peripheral edge on which the canned body now rests on the floor, has a finite width in this known embodiment; it merges slightly into the side wall.
• the object of the invention is therefore to propose such a can body.
• the invention solves this problem by means of a can body with a base and a peripheral side wall projecting therefrom and surrounding an interior space and which delimits an opening of the interior space all around with its upper edge, the interior space expanding conically upwards and the the side wall surrounding it merges into the floor in a curve in such a way that a circumferential ring-shaped support line is formed, but the floor is initially extended further upwards, but then a support surface with a width of 1.5 mm, in particular from 2 to 10 mm.
• Such a can body has a considerable number of advantages: on the outside, its support surface is given by an annular line when it is parked. Further inside is an additional contact surface with a defined width, which extends approximately parallel, ie also in a ring shape, to the contact line. The combination of these two support areas is shown to increase stability in tests. In a figurative sense, a kind of three-point support is created, namely by a flat and a linear support, ie a distance and a point on average.
• This contact surface is not only particularly stable against forces from the side, from below or also from the can body itself, it is also immune to manufacturing tolerances and resists, for example, expansion and bending forces originating from the inside of the can body. These forces can arise not only from the filling of the tin can, but also when a row of empty tin can bodies is put into one another.
• the side walls which flare conically upwards, enable empty cans to be placed inside one another in a space-saving manner after they have been manufactured and before they are filled in the food processing company.
• this leads to forces that the empty can bodies exert on one another. Exactly these forces are intercepted by this special training of the soil. It is particularly preferred for this if the upper edge around the opening has an edge profile with three alternating curvatures which form a shoulder or a step edge.
• the can body is made of metal.
• the features according to the invention have proven particularly advantageous in the case of metallic bodies in the test.
• the curve has a radius of curvature of more than 4 mm.
• the curvature at which the side walls merge into the floor is decisive for the extent of the line shape of the support line, and also for the behavior of the can body when it is brought out of its rest position, for example in a filled form on the shelf of a supermarket. Due to the relatively large curvature with a large radius of curvature, the self-adjustment of the can body in filled form is particularly inexpensive to accomplish. The visual and aesthetic appearance is also of greater advantage; the result is a spherical, soup-pot-like shape that is particularly attractive.
• the opening is circular. Of course, however, it is also possible to provide oval, approximately rectangular or completely differently shaped openings, the shape of which then of course also has an effect into the bottom area.
• the distance between the support line and the support surface should advantageously be between 7 and 30 mm. With these dimensions, the even distribution of the forces acting on the ground is particularly effective.
• the diameter of the annular contact surface should be approximately 20 to 80 mm. This also reinforces the inventive effect.
• the ability to stack and unstack cans, particularly those that are not round, is further improved if the side wall is provided with corrugations. These corrugations make the circumferential side wall so stiff that the side wall does not compress. As a result, the can body keeps its shape even when under stress. Such a load can occur in particular during the filling of the can containers, especially when the lid is flared after filling. It is precisely during this section of the process that the shape of the body is important in order to ensure that the lid and container are superimposed on one another in order to enable the flaring process, in which the materials of the can body and the associated lid are folded into one another.
• the ability to be stacked and unstacked is also important, since the still empty tin can bodies without a lid must be able to be placed one inside the other in a space-saving manner, and then, if possible, they must also be able to be disassembled by machines so that the top tin can body does not lift when next with follows. This is also supported by the ripples. This is particularly true when the corrugations are essentially vertical.
• the corrugations extend downward from the area of the or one of the shoulders over a substantial part of the side wall.
• the corrugations not only have the task of stiffening the side wall, but also of guiding the various can bodies into one another, precisely during the stacking or unstacking process. By running the corrugation upwards, an easy, even removal is possible here.
• FIG. 1 shows a cross section through a canned body according to the invention
• Figure 2 is a top perspective view of the can body of Figure 1;
• FIG. 3 shows the can body from FIG. 2, partially cut away and with a similarly illustrated, not yet firmly attached lid;
• Figure 4 shows another embodiment of a can body seen obliquely from above
• Figure 5 shows the embodiment of Figure 4 obliquely from the side with two alternative options for a design of the lid
• Figure 6 shows a third embodiment of a canned body according to the invention.
• a can body has a base 10.
• a side wall 20 projects from this base 10.
• the side wall 20 surrounds an inner space 30.
• the goods to be transported and stored in the can, in particular thus food, are introduced into this inner space 30.
• the upper edge of the side wall 20 surrounds an opening 31 of the interior 30 all around; this opening can (as indicated in FIGS. 3 and 5) be closed by a cover 40 and, as a rule, this becomes after filling with the filling material.
• the interior 30 widens conically upwards. This means that the circumferential side wall 20 projecting from the floor extends upwards.
• the side wall 20 merges into the floor 10 in a curve 21. This is done in such a way that the curve 21 forms a circumferential ring-shaped support line 11.
• the rounding itself has a radius of curvature of, for example, 4.5 mm or 8 mm for can bodies of typical sizes.
• this support line 11 appears as a point in FIG. Looking further towards the center of the can body bottom 10, however, the base 10 initially moves inwards from the support line 11, so it leaves the support level.
• a circumferential annular bead 15 projects again downward.
• this bead 15 now does not form a support line, but rather a support surface 16 with a width of 1.5 to 10 mm.
• this support surface is shown as a section with a length of 1.5 to 10 mm.
• the bead 15 can also be seen obliquely from top to inside; from the interior 30 it shows itself as a projection downwards with no shading whatsoever owing to its flat, flat design. Also flat and without shading is the central area of the bottom 10, which, in contrast to the bead 15, does not lie on the bottom when the can body is turned off.
• the opening 31 of the interior 30 is, as stated, surrounded by the upper edge of the side wall 20. This is provided as an edge profile with three bends which are alternately bent inwards or outwards and which form a shoulder 22 or a step edge.
• their conically shaped side walls 20 project into one another, the side walls running parallel to one another at a slight distance from one another.
• the shoulders 22 then rest on one another. This stacking behavior is supported by the bead 15, which favors the stability and thus also the centricity behavior of the containers.
• FIG. 3 shows the embodiment from FIG. 2 in a less steep manner, and the right quarter of the can body facing the viewer is cut away. A cut edge can thus be seen, which corresponds to that in the right field of FIG. 1, but at the same time also illustrates the curves and proportions that result in three dimensions.
• the cover 40 is shown (not cut away) at a distance above the opening 31.
• FIGS. 4 and 5 Another embodiment of a can body is shown in FIGS. 4 and 5.
• the opening 31 is not circular, but rather rectangularly stretched with rounded corners, that is to say approximately oval.
• the annular bead 15 and the annular support line 1 1 each also have straight passages.
• the side wall or side walls 20 are conically slightly divergent at the top.
• FIG. 6 A third embodiment of the invention is shown in FIG. 6.
• This embodiment is also a spherical box and has an out-of-round, slightly conical shape similar to the embodiment of FIGS. 4 and 5, here additionally a step edge 22 with side ridges 25.
• FIGS. 4 and 5 A third embodiment of the invention is shown in FIG. 6.
• This embodiment is also a spherical box and has an out-of-round, slightly conical shape similar to the embodiment of FIGS. 4 and 5, here additionally a step edge 22 with side ridges 25.
• some are here Reference numerals omitted which correspond to those of the other figures.
• the container or can body has a relatively large radius at the transition from the side wall to the bottom 10.
• the circumferential side wall 20 is so stiff that the side wall 20 does not compress. As a result, the body retains its shape and allows good material overlap between the lid 40 and the container, so that the lid 40 can be securely flared.
• the body to be stacked can rest on a first circumferential or locally interrupted shoulder of the lower can body located in the area of the opening 31.
• a distance is formed between the edges of the two bodies, which enables the containers to be stacked one below the other.
• the corrugations 25 run upwards in the region of the side edge 22, that is to say at the level of the second shoulder, between the first and second shoulder or in the first shoulder.
• the leadership of the side ridges 25 in connection with the Shoulder causes an extremely good wall rigidity, so that the force of the flanging tools transmitted to the side wall 20 does not lead to their deformation during flanging and, on the other hand, in the case of canned bodies stacked on top of one another which are filled and closed, even when filling the side walls 22 necessary rigidity against buckling or buckling.
