Definitions
- the technical field of the invention is the two-part metal beverage can.
- the invention relates to such a beverage can according to the preamble of claim 1. It is shown in Fig. 10 of WO-A-83/2577.
- the mentioned figure of the prior art shows a can body made of aluminum with a profiled base for drinks under pressure.
- the sheet thickness of the bottom area of this box is 0.295mm and larger.
- the subject of the discussion of the figure mentioned is the intermediate floor area. It is located between the dome-shaped central base section and the container body.
- the intermediate floor area has a V-shaped structure, the two legs of the intermediate floor area which is V-shaped in cross section being inclined outwards from the vertical of the can and having different lengths.
- the lowest point of the V-shape is slightly rounded.
- the - in cross-section V-shaped - bottom intermediate region has the result that two frustoconical bottom sections are created, an inner bottom section and an outer bottom section.
- the inner bottom section is the one that FIG.
- the invention is different.
- the invention achieves the aforementioned object in that the frusto-conical inner bottom section and the frustoconical outer bottom section have a U-shaped cross section, both frustoconical bottom sections being inclined from the horizontal, in such a way that the angle of inclination ⁇ of the frustoconical outer bottom section is greater or equal is the angle of inclination ⁇ of the frustoconical inner bottom portion. Both angles are related to the "horizontal", which is a reference plane that is perpendicular to the "vertical” (can axis).
- the angle ⁇ of the inner bottom section can be determined from the ratio of two radii (R2 / R1), where R1 is the radius of curvature of the central bottom area and R2 is the spherical section radius of the mentioned central bottom area (claim 2).
- the frustoconical bottom sections have approximately the same inclination and this inclination is the inclination of the radius of curvature of the central bottom region (R 1R ), the arrow end of which lies at the point of intersection with the sphere section radius of the central bottom region (claim 3) .
- a preferred wall thickness in the area of the floor is less than 0.28 mm (claim 5). Such a reduction in the sheet thickness is only possible through the aforementioned angular relationship of the intermediate floor section.
- An advantageous spacing of the two truncated cone-shaped bottom sections mentioned claim 4, it is 2mm.
- the sheet thickness can be reduced and the cost of materials can be reduced. This decisively determines and lowers the manufacturing costs. Especially The invention avoids the jumping over of the central floor area which still occurs in the prior art, even if significantly smaller sheet thicknesses are used than in the prior art.
- the high level of dimensional stability - even with internal pressures greater than 6 bar - can be guaranteed, although the cans manufactured in mass production can be manufactured with substantial savings in material and costs. This is based on the relationship between the inner conical wall section and the essentially beginning (starting) central floor section which adjoins it at right angles, which is thereby secured with a high degree of reliability against any tendency to jump around.
- the usual beverage can shown in FIG. 1 is one with a conventional base profile.
- the cylindrical body 1 of the can manufactured in one piece by deep drawing and ironing has an outer annular Bottom section 3, which has the shape of a truncated cone. Its smaller diameter points downwards and is connected to a central, dome-shaped base portion 4 via an intermediate base portion in the form of a radius of curvature.
- the intermediate floor section is designated by 5.
- the central section 4 of the base 2 takes up the greater part of the diameter of the base. Its radius is much larger than half the can diameter.
- the can is rotationally symmetrical with respect to the container axis 6.
- the base geometry of the two-part beverage can according to the invention is shown in FIG.
- the cylindrical body 8 merges into an outer truncated cone-shaped base section 9 over a radius of curvature.
- the area of the smallest diameter lying deeper in the axial direction is connected via a bottom intermediate section 11 to the central bottom section 10, which in turn is dome-shaped and projects into the interior of the container.
- Figure 2 also shows the can 7 in a stack with an underlying can 12, the outwardly domed lid 13 is connected to the body of the can 12 via a seam 14 forming a truncated cone surface.
- the outer truncated cone-shaped base section 9 is inclined and dimensioned such that, as shown in FIG. 2, it engages in the truncated cone-shaped seam 14 when stacked and thus ensures a secure, wobble-free stand.
- the bottom geometry of the new can also enables safe stacking in conjunction with other lid shapes and other connecting seams between the lid and the container part of the two-part beverage can.
- FIG. 3 Details of the floor geometry can be better seen in FIG. 3, in which a floor half is shown on a larger scale.
- the cylindrical body 8 merges over a small radius of curvature 16 into the frustoconical outer bottom section 9.
- the edge of the dome-shaped, projecting central base section 10 is provided with an edge curvature 17 with which the central base section is continuously connected to the intermediate floor section 11.
- the intermediate floor section 11 has a U-shaped cross section, the two legs being formed on the outside by the frustoconical outer bottom section 9 and on the inside by a frustoconical wall region 18 of the intermediate floor section 11.
- the narrower diameter of both frustoconical wall areas lies axially further down and closer to the container axis than the further edges of these edge sections.
- the two frustoconical wall regions 9 and 18 are connected to one another via a wall section 19 which is circular in cross section.
- the outer frustoconical bottom section 9 forms an angle ⁇ with a plane running perpendicular to the container axis. This can be between 20 and 60 ° and is preferably about 40 °.
- the frustoconical wall region 18 of the intermediate floor section 11 forms an angle ⁇ with the same plane. This angle is preferably selected depending on both the radius of curvature R 1 and the radius of the spherical segment R 2 of the central base region 10.
- the angle ⁇ can be the same size or smaller than the angle ⁇ . Both angles are preferably the same, so that the two frustoconical wall regions run parallel to one another and to the radius R 1R .
- the lengths l1 of the outer frustoconical bottom section or l2 of the frustoconical wall area 18 of the intermediate floor section 11 are variable, with l2 in the preferred embodiment being significantly smaller than l1.
- the length l2 can also be zero, so that the radius of curvature r2, which connects the two frusto-conical wall areas, comes closer to the container axis than the radius of curvature r3, which connects the intermediate floor section 11 to the central section 10 in FIG. 3 and 27 in FIG .
- the radius r2 can be between about 0.5 and 4 mm and is preferably about 1 to 1.5 mm.
- the bottom wall thickness can be significantly less than 0.28 mm without reducing the internal pressure stability of the bottom.
- the known electro-dip painting is expediently used, since this ensures problem-free and reliable painting of all areas of the floor.
- the production of the new floor geometry does not require any special measures except that a further deformation process is switched on after the deep-drawing and ironing process.
