Definitions

  • the invention relates to a three-part packaging made of metal or metal / plastic composite film, with the features of the preamble of claim 1.
  • DE-C-946 273 discloses a stackable container with a push-in lid.
  • an annular contact surface for the bottom end of the packaging is formed on the ring of the push-in lid side or the like, which is radially on the outside or radially on the inside by a collar projecting in the axial direction is limited.
  • the mutual coordination of the deformations of the two fold seams takes place in such a way that when the packages are stacked there is only a safe telescopic engagement of the fold seams over only a limited part of the axial height of the fold seam.
  • the body, lid or cover ring, bottom and the double seams required to connect the parts remain essentially unchanged compared to conventional packaging of this type. It is only the cross-sectional outline of the bottom-side and lid-side seams that are changed so that when they are stacked, the seams telescope over part of their axial dimensions. In this way a good stackability is obtained without the hull having to be drawn in at its ends.
  • fold seam It is not critical what type of fold seam is, i.e. whether it is a single fold, a double fold or a multiple fold.
  • both the bottom rebate and the lid-side rebate with such an interlocking radial gradation, the two gradations being matched to one another, so that a smooth but secure intervention is possible. It is not critical whether the shoulder-like enlargement is assigned to the bottom fold or the cover fold and the shoulder-like narrowing is assigned to the other fold. For production, however, it is expedient to assign the radial expansion of the inner diameter of the axially outer section of the fold seam to the cover-side fold.
  • the gradation of the fold is expediently carried out during the manufacture of the fold by using appropriately profiled sealing heads and / or sealing roller profiles.
  • the shoulder is expediently located directly outside the overlap area of the lid hook and trunk hook.
  • the bottom seam fold can also be produced in the usual cylindrical orientation and with the usual tools on the conventional machines. Additional funds are only required for the subsequent step that compresses the seam into the conical shape.
  • the invention is preferably applicable to three-part packaging in which a bottom part or a cover part or cover ring part is fastened in a sealing and permanent manner at the two ends of a body part by means of a seam.
  • the fuselage and / or base and cover part have corresponding edge flanges.
  • the fold connections can be formed in any conventional manner, regardless of whether it is a single fold or a double fold seam or is a multiple fold.
  • packages 1 and 2 are of the same overall design, so that the instructions given for one package also apply equally to the other package.
  • the packaging consists of a cylindrical body 3 of any cross-section, which has an outwardly bent edge flange at its two ends from manufacture.
  • the lower end is closed by a preformed bottom part 4, which in the example shown has an edge flange starting from the core wall.
  • the flanges at the lower end of the fuselage 3 and the bottom 4 are firmly, tightly and permanently connected with conventional tools of a closing machine, that is to say with the aid of a central closing head and outer closing rollers, to form a fold seam, in the example shown to a double fold seam 5.
  • the double seam 5 on the bottom side extends after its production essentially in axial alignment with the cylindrical body 3.
  • the compression ring 10 has a conical inner surface 11 which is inclined relative to the axis of the compression ring at an angle 12 which is between 5 ° and 15 °, preferably between 7 ° and 10 °.
  • the compression ring is pressed in relation to the packaging in the direction of arrow 13, as a result of which the double seam 5 is drawn in radially in the direction of arrow 14.
  • the transition between the conical seam region and the cylindrical fuselage is indicated in FIG. 1 at 3c, 3a being the original cylindrical fuselage wall and 3b the lower conical part of the fuselage wall. In this way, the bottom rebate is significantly reduced in its outer diameter and brought into a conical position.
  • the packaging 2 is closed at its upper end by a cover part 7, which has a flange adjacent to its core wall, which is deformed together with the edge flange of the fuselage 6 into a fold seam, in the example shown a double fold seam.
  • a specially designed closing head 15, as shown in FIG. 3, is used in the production of this double fold seam 8.
  • This closing head 15 engages in the cover placed on the end of the fuselage and has an annular shoulder 16 at a distance from the axially outer edge of the double seam, over which the closing head 15 is correspondingly expanded in its upper region. It can also be seen that the closing head 15 below the shoulder 16 and above the shoulder in each case has weakly tapered peripheral walls 17 and 19 respectively.
  • the radial expansion of the shoulder 16 is indicated at 21.
  • the angles of inclination of the peripheral sections 17 and 19 are shown at 18 and 20, respectively. They are expediently between 5 ° and 15 ° and preferably between about 7 ° and 10 °.
  • This double fold seam is preferably shoulder-like in its inside diameter, preferably directly above the area 26 over which the trunk hook and the cover hook overlap, the shoulder dimension corresponding approximately to the dimension 21 of the shoulder 16.
  • This extension extends over the outer region 27 of the axial length 25 of the double fold seam 8. Over the length 27, when the same packages 1 and 2 are stacked on top of one another, the fold seams are telescopically engaged, the extent of the engagement being indicated by 9 in FIG.
  • the design of the fold seam on the cover side according to FIG. 3 can advantageously also be used in two-part containers in which the bottom, which is integrally connected to the fuselage, is dimensioned and conical in accordance with the fold 5 on the bottom.
  • shoulder-like shoulders are provided in the bottom-side and in the lid-side fold.
  • the closing head 36 and a special profile 34 of the associated closing rollers 33 With the help of the closing head 36 and a special profile 34 of the associated closing rollers 33, the bottom seam seam between the fuselage 30 and bottom 31 is provided with a shoulder-like reduction in the outside diameter of the seam seam in the area above the overlap area 35 of the bottom hook and body hook, as is the case with the shaping shows the upper part of Figure 4.
  • the closing head 36 can have a slightly conical peripheral wall 37, so that the fold seam 32 is weakly conical overall.
  • the fuselage 40 is connected to the cover 41 by means of the fold seam 42, using a closing head 46 provided with a special profile 47, 48.
  • the profile in the upper region has a circumferential nose which projects radially to a considerable extent and which has a shoulder 47 forms.
  • the area 43 of the double fold seam 42 above the overlap area 45 of the hook sections lying in the fold is enlarged shoulder-like with respect to the inside diameter.
  • the shoulder-like deformations on the two fold seams are coordinated with one another in such a way that the outer areas can interlock easily but with little play.
  • the relatively large circumferential nose of the closing head 46 causes a relatively high load on the folded parts, which can impair the controlled fold formation at the high production or closing speeds.
