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.
• fold seam It is not critical what type of fold seam is, whether it is a single fold, a double fold or a multiple fold.
• both the bottom rebate and the cover-side rebate with such a radial gradation which enables intermeshing, the two gradations being matched to one another, so that a smooth but secure engagement 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 grading of the fold is expediently carried out during the manufacture of the fold by using appropriately profiled closing heads and / or closing roller profiles.
• the shoulder is expediently located directly outside the overlap area of the lid hook and trunk hook.
• it is cheaper and more advantageous to first form the bottom fold in the usual cylindrical, smooth, shoulder-free shape and to fold in a subsequent step into a conical shape that tapers axially outwards and radially inwards.
• This makes it possible to emboss the shoulder in the lid-side fold less radially, so that it is possible to work with a closing head with a significantly reduced heel. , This facilitates the formation of the lid-side fold with shoulder-like expansion without impairing the high speeds of modern sealing machines and without impairing the strength and tightness and reliability of the seam connection.
• the manufacture and closing of the packaging can be based on lower parts or body parts and lids or cover rings as well as base parts which correspond exactly to the parts customary for this packaging in terms of their geometric shape and dimensions .
• the bottom seam seam can also be produced in the usual cylindrical direction 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.
• Figure 2 in a representation similar to Figure 1, the bottom fold of the upper package of Figure 1 before the final step, the fold compressing.
• FIG. 3 in a similar representation as Figure 1, the lid-side fold and the associated closing head with details and
• FIG. 4 shows a modified exemplary embodiment in a similar representation to that of FIG. 1, but the tools required for the production are, if necessary, also shown in the engaged position.
• the parts of the packaging can be made of the same or different materials.
• Metal sheet or metal foil or metal / plastic composite foil can be used for the production.
• the invention is preferably applicable to three-part packagings in which a bottom part or a cover part or cover 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 rim 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 treated in the cutout, which are stacked one on top of the other in FIG. It is assumed that 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 become firm, tight and permanent with a conventional closing tool, that is to say with the aid of a central closing head and outer locking rollers, into a fold seam, in the example shown into a double fold seam 5 connected.
• the double-fold 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 area and the cylindrical body is indicated in FIG. 1 at 3c, 3a being the original cylindrical body wall and 3b being the lower conical part of the body wall. In this way, the bottom rebate is significantly reduced in its outer diameter and brought into a conical position.
• the package 2 is closed at its upper end by a cover part 7, which has a flange adjacent to its core wall, which flange is deformed together with the edge flange of the body 6 into a fold seam, in the example shown a double fold seam.
• a specially designed closing head 15 is used, as shown in FIG. 3.
• This closing head 15 engages in the lid placed on the fuselage end and has a ring shoulder 16 at a distance from the axially outer edge of the double fold seam, via which the closing head 15 is correspondingly expanded in its upper region.
• 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 °.
• FIGS. 1 and 3 Correspondingly adapted closing rollers cooperate with the closing head 15, so that there is a double fold seam, as shown in FIGS. 1 and 3.
• This double fold seam is preferably shoulder-like in its inner diameter, preferably immediately 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 via the fold seam 42, using a closing head 46 provided with a special profile 47, 48.
• the profile In the upper region, the profile 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 formation of folds at the high production or closing speeds.
