Definitions

  • the invention has for its object to provide an embossing device consisting substantially of a patrix and a matrix, which is suitable for providing contain- 5 ers which have been prepared in a sleeve-like manner with the necessary folding creases or folding edges required for the closure part which is to be folded.
  • the raised places and the depression on'the The raised places and depressionson the patrix and the matrix may also be formed by surfaces which form an angle with one another and by vmeans' of which the circularor elliptical cross section of the container is transformed into an 5 annular cross section: In doing this it is possible to cause the arcuate container wall to merge 'into the closure part either gradually or with a bounding edge extending preferably in an arcuate fashion.
  • the surfaces on the patrix and matrix which form an angle with one another may also be jointly used with folding ridges and grooves, so that for instance the convex folds are formed by the edges, where the surfaces abut against each other, whilst the concave folds or folding grooves are produced by means of folding ridges provided on the matrix and corresponding grooves provided on the patrix.
  • sharp folds may be produced at the place where the closure part merges into the container body through the patrix and matrix being formed at the place of transition with somewhat different diameters.
  • the device according to the invention can be made suitable for containers which narrow conically towards the closure part for cylindrical containers and for containers which flare conically towards the closure part.
  • the hollow body forming the matrix need not be capable of being taken apart as the embossing operation is effected entirely bythe axial insertion of the patrix. There is of course no reason why the matrix should not be made divisible, for instance for cleaning purposes.
  • Figure 1 shows a device for conically narrowing containers in an axial section.
  • Figure 2 is as to one half a plan view of the empty matrix according to Figure 1, and as to the other half asection through the patrix and the matrix on line II--II of Figure 1.
  • Figure 3 shows a container stamped by means of the device according to Figures 1 and 2 with the folds formed according to the folding grooves for preparing it for closing.
  • Figure 4 shows a device for cylindrical containers in axial section.
  • Figure 5 is a section on V-V of Figure 4.
  • Figure 6 shows a container stamped by means of the device according to Figures 4 and 5.
  • Figure 7 shows a device for conically flaring containers in axial section.
  • Figure 8 is a section on VIII-VIII of Figure 7.
  • Figure 10 is a section on X--X of Figure 9.
  • Figure 11 shows in axial section a matrix similar to that of Figure 9 for the production of con vex folding edges by means of surfaces at an angle to one another and of concave folding grooves by means of foldinglines.
  • Figure 12 is a plan view of Figure 11.
  • Figure 13 shows the matrix of Figure 11 with.
  • the patrix inserted in it and the container between them in the stamping position, the patrix being shown in elevation and the matrix and the container in axial section.
  • Figures 14 and 15 are perspective views of a container provided with folding edges and folding grooves by means of the device according to Figures 11 to 13, before being folded and after the folds have been made corresponding to the folding edges and grooves.
  • the device according to Figures 1and2 consists substantially of the patrix I and the matrix 2.
  • the patrix is in the form of a truncated cone and may also be used as the mandrel for wrapping the container 3 which narrows conically towards the closure part.
  • the patrix I is provided with four folding ridges two of which are indicated at 6 and 'l' in the right hand part of Fig. 2 and the matrix with four corresponding grooves 4" to 1".
  • the patrix also has two grooves 8' and 9 and the matrix two corresponding folding ridges 8" and 9".
  • the folding ridges will be displaced parallel to the associated folding grooves and approached to the latter, until, pressing the container wall between them, they engage a short way one in the other.
  • the lower bounding edges II) to I2 of the folding part thus form themselves.
  • Special means may however be provided forforming lower sharp bounding bends for the folding part, which means shall be herein after described.
  • the patrix I3 is a substantiallycylindrical body which is offset at I4 so that the lower part has a somewhat smaller diameter. On the offset-part it is provided with longer folding ridges I and shorter folding ridges I6, which project to such an extent as to be fiush with the peripheral part of the cylinder I3, which is not offset.
  • the matrix I1 has its lower part offset at the edge I8 so as to project inwardly, this inwardly projecting surface being provided with grooves I9, into which the folding ridges I5 and I6 can be inserted in the longitudinal direction.
  • the folding r dges to be formed only on the patrix and for the matrix to be provided only with grooves.
  • the container sleeve is provided with slightly convex this way only convex folding'grooves are formed in the container 20, whilst it must have both convex folds 2I and also concave folds 22.
  • the container 20 and, correspondingly, the patrix I 3 and the matrix I1 are arranged for the production of concertina like folds of the kind known per se.
  • the lower sharp bounding bends 23, 24, 25'of the folded in surfaces either form themselves or special means may be provided for this purpose which shall be hereinafter described.
  • the arrangement according to Figures 7 and 8 corresponds substantially to that of Figures 1 and 2.
  • the folding ridges, for instance 22, and the grooves, for instance 23, are formed not at the lower, but at the upper end of the patrix 24 and of the matrix 25.
  • diameter d of the patrix 26 at the lower ends of the edges 29 must not be smaller than the diameter (1 of the patrix at the place at which the curved peripheral surface merges into the surfaces which are arranged at an angle to one another.
  • the patrix 35 and the matrix 36 in Figures 11 to 13 are provided both with surfaces 31 arranged at an angle to one another for forming concave folding edges 38 and with folding edges 39 and as-' sociated folding grooves 40 for forming concave folding edges 3I of the container 42.
  • the surfaces 31 at an angle to one another of the patrix 35 and the corresponding surfaces 33 of the matrix are so formed that with their bounding edges 44' and 44" they stand out slightly beyond the curved peripheral surface of the patrix 35 or form slightly depressed surfaces in the matrix 36.
  • the features described in the various constructional examples may also be employed in combination with one another.
  • the number of folding grooves or folding edges to be formed is of course optional, as it depends on the form of the container and on the number of corners, the style and shape of the closure part.
  • the folding grooves may be stamped throughout the whole length of the container. Sharp edges at the places of transition in the patrix and matrix should as far as possible be avoided, so that the paper will not be damaged.
  • a device for stamping folding grooves and folding edges for the folding closure of containers made of paper and similar materials comprising a patrix and. a matrix capable of axial motion with respect to one another for applying internal and external pressure to the container blank and provided with raised and depressed places capable of sliding one within the other during the stamp the raised and depressed places of the patrix andthe matrix have the form of surfaces at an angle to one another and capable of displacement parallel to one another.
  • a device as claimed in claim 1 characterized by the joint use of folding ridges and grooves for longitudinal folding edges and surfaces forming an angle with one another for transverse edges of the folding closure.
