Definitions

  • the bottom flaps form the bottom of the packing casing and defining perforations in the corner ranges for the passage through of the guide members controlling the piling up of individual packings.
  • the individual packings have setting edges and are guided during this piling up and at least parts of the perforations are disposed tangentially to the setting edges.
  • the present invention relates to a packing container or casing g formed of a folding cardboard blank with rectangular, in particular, square cross section for reception of tetra-hedron-shaped individual packings.
  • soft packings with bottom-and cover-flaps and shows simultaneously an apparatus for filling of the packing cases with tetra-hedron-shaped individual packings.
  • the present invention should find its application for the packing of a plurality of tetra-hedronshaped soft packings for milk, drink chocolate, fruitjuices, etc.
  • a packing case suitable therefor, is created, which permits a guide of the individual soft packing during the piling up in the packing case.
  • an apparatus is to be disclosed which permits in conjunction with the packing case particularly simply and safe by the production of the collection packing.
  • the packing casing of the above described type is in accordance with the present invention characterized by the fact, that the bottom flaps forming the bottom of the packing case has perforations in the corner ranges for the passage of guiding members controlling the piling up of the individual packings, whereby the perforations or part thereof are disposed tangentially to the cap edges of the individual packings to be guided during piling up.
  • the thus formed packing case it is possible, to guide orderly the individual tetra-hedronshaped soft packing during the pilling up in the packing container and to support the same in the storing position.
  • By this arrangement of the individual soft packing there is obtained a defined end position relative to the further five soft packings, which joints are stored one after another in a layer.
  • the individual packings are retained with their edges and corners partly by the rectangularly or squarely shaped packing case or its wall cushions, respectively, and partly by the guide members of an apparatus disposed on the packing machine.
  • the bottom flaps are disposed also in the corner ranges covering each other which are equipped with perforations.
  • Two perforations each corresponding with each other of two adjacent bottom plates are arranged at least partly flush so that the guide members can extend from below through the bottom and in the inner space of a packing case.
  • the perforations are thereby always arranged such, that the guide members with their guide face the cap edge engages tangentially four of the six soft packings disposed in the lowest layer.
  • protection flaps are provided at the bottom flaps for the formation of protection flaps cut to form perforations, which protection flaps fill out in the closing position the perforations substantially.
  • These protection flaps perform a double function. In the first place they serve the protecting support of the individual soft packing in the case by arranging the same as a pillow between the setting edge of the soft packing and the guide member of the auxili ary device. On the other hand, however, the protection flaps are transformed by the pressure of the soft packing nearly completely into the closing position so that the perforations are covered up.
  • the protection flaps have thereby bending edges, which are arranged pointing to the individual packing. By this arrangement the opening direction of each protection flap is secured in the inner space of the packing case.
  • the protection flap can be disposed either only in the comer ranges of the bottom flaps or in addition in the range of a center opening, in case such center opening finds application.
  • the protection flaps are arranged only in the corner ranges of the bottom flaps.
  • the bending edges of the protection flaps are disposed in or slightly parellel to the supporting edge of the individual packing coordinated thereto. This information results, on the one hand, in a particularly good guiding and support of the set of the set off individual packing, and on the other hand permits the swinging of the protection flap into the closing position. An interconnection between the setting edge of the soft packing and of the protection flap does not occur.
  • a pyramidshaped folded insert, a pyramid-shaped setting face, or the like can be applied, which insert is inserted either as a particular part in the packing casing or is folded of parts of the bottom flaps. It is however, also possible that the bottom flaps overlap at least one corner range, are perforated at the outer edge for the formation of a center opening in the casing bottom for the passage of a further guiding member for the individual packings which guiding member is provided centrally and on the table of the packing device.
  • the thus formed packing casing has also at the bottom practically five perforations and in particular a larger in the bottom center and the already described smaller perforation in each corner range.
  • the packing container is mounted on the packing device, whereby a pyramid-like cover reaching through the center opening, forms a central guidance member or the like, the support for the part of the individual packing disposed in the container center, while pins, fingers or the like form guiding members, which reach through the perforations in the corner range, form during the filling abutments for the setting edges of the individual packings.
  • the once piled up individual packings support themselves also after the removal of the filled packing case from the filling machine on each other and on the outer walls of the packing casing, respectively. They retain their piled up arrangement.
  • the total packing casing is to be produced particularly economically due to its low material requirement and its simple form upon removal of additional inserts. It can be transported and stored easily due to its square or rectangular form, respectively and requires only little space.
  • the side length of the container bottom face corresponds with the key width of a hexagon formed by the edges of the tetrahedron-shaped packing.
  • the bottom flaps reach outside the range of the center opening up to the center of the container bottom. They are overlapping at least one corner range, stamped out at the outer edge for the formation of the center opening in the container bottom on one side or U-shaped and equipped with the perforation at the corner range.
  • the center opening in the casing bottom can also be formed as an arc of a circle of the superposed bottom flaps. Also the center opening is advantageously equipped with protection flaps.
  • these guide members are formed by studs, pins or the like.
  • the plate or the frame has its outer periphery upright standing feed sheets or the like which are preferably extended upwardly as much, that they grip and hold during the filling cover strips engaging the outer walls of the packing casings.
  • the insertion or mounting of the packing casing is thereby simplified, the guide sheets are bent outwardly at the outer end.
  • the plate, the frame or the like corresponds in its periphery with the base face of the pacing casing to be filled. The lifting of the filled container from the plate can easily be performed, by providing corresponding recesses at the outer edge of the plate and of the frame, respectively, which recesses permit an undergrip of the container bottom.
  • the plate in accordance of the present invention forms a simple auxiliary device, which can be mounted exchangeably without difficulty on the turn stile of the conventional filling machines. It is thereby also possible depending thereby on the formation of the turn stile to provide a plurality of such plates adjacent each other or in series relative to each other.
  • the device in accordance with the present invention has abutments, coupling parts or the like, which permit without change of the turn stile the mounting of the device in a simple manner.
  • a guide member formed as pyramid-shaped cover and projecting through the center opening of the bottom of the packing casing which guide member carries at its upper side star like disposed feed sheets corresponding with the position of the individual packings to be piled up.

  • the side parts 10 of the blank are equipped with an end tongue 11 and the conventional cover tongues 12. Furthermore in the side walls 10 recesses, perforations or the like can be provided, which form a carrying grip. It is also possible to provide here bearing bands of carrying tongues.
  • the bottom flaps l3 and 13', respectively, of each blank reach conventionally to beyond the casing center and have a bow shaped cut up 14 or 14'. In the corner regions or ranges of the bottom flaps 13 or 13', respectively there, are disposed perforations 15 and 15, which come into cover during erection of the packing casing and during folding of the bottom flaps.
  • Perforations 15 and 15' are disposed in this first embodiment along the diagonal of the bottom of the packing cardboard.
  • the perforations 15 and 15 are formed here as circular stampings. It is to be understood that perforations 15 and 15' can assume also other forms. It is merely essential that the perforations l5 and 15' of two adjacent bottom flaps 13 and 13' cover each other at least partly.
  • FIG. 2 a further embodiment of said packing casing is shown in a top plan view.
  • the perforations 15 are here however, disposed outside of the diagonal.
  • the bottom flaps 13 form in the center a bottom center opening 16. This is not required, yet shows to be in most cases as suitable.

At one end is disposed within the range of the side parts 1 and of the cover tongue 12 and end tongue 11 for closing of the packing casings.
  • Each bottom flap l3 and 13 has a perforation 15 for the passing through of guide members for controlling the piling up of the soft packings, which guide members are covered here by the cut protection flaps 18.
  • the bottom flaps 13 have beyond that perforations 15, which can have the form of round holes.
  • the bottom flaps 13' have no particular stamping or perforation.
  • the periphery of the bottom flaps 13' is arranged such, that at the corresponding point the material of the bottom flap 13 is removed.
  • a center opening 16 can be disposed which is formed and covered by the cut protection flaps 18.
  • the protection flaps 18 can be pointed towards each other with their free ends, as shown or as shown can be transformed for production reasons into a perforation.
  • Each cut protection flap l8 and 18' has a bending edge 19 and 19', which permits a swinging of the protection flap 18 and 18' from the plane of the bottom flap l3 and 13 into the inner space of the packing casing and again back to the plane of the bottom.
  • the protection flaps 18 and 18 and the bending edges 19 and 19 are arranged such, that the bending edges 19 and 19' are disposed either in or parallel to the corresponding cover edge 10 of the individual packing 17. By this arrangement also the possibility presents itself, that the protection flap l8 and 18' due to the pressure of the individual packing 17 move into the closing position.
  • FIG. 3 a casing blank is shown, the side parts of which are of equal length. Accordingly one deals here with a packing casing with a square ground face. It is, however, also possible to choose a rectangular ground face, whereby the one side wall corresponds with the key side of the regular hexagon inserted by the individual packings 17, while the adjacent side parts have a length, which corresponds with the distance of two oppositely disposed comers of the regular hexagon.
  • the arrangement of the protection flap l8 and of the perforations 15' can as shown take place in the diagonal at the bottom. This is, however, not necessary.
  • the protection flaps l8 and perforations 15 are arranged in the corner ranges of the bottom flap 13 and 13 such, that they are disposed partly or completely tangentially to the setting edges 20 of the individual packings 17.
  • the protection flap 18 and the perforations 15 of two adjacent bottom flaps l3 and 13' are arranged such, that they overlap each other in erected position of the packing container at least partly.
  • the arrangement of the protection flaps 18 does not require the arrangement of protection flaps l8 and vice versa.
  • the device comprises substantially a plate 1 which has an opening 2 in its center, which is bridged over by a stay 3, on which a central guide member 4 is secured in the design as a pyramid shaped cover. From starting from the center opening 2 slots 5 are provided which serve the mounting of the plate on the turnstile of a filling machine.
  • the plate 1 At the outer sides of the plate 1, the latter is equipped with recesses 6, which serve the under gripping of the filled packing casings to be mounted on the plate. Furthermore, at the corner of the plate 1 sits upwardly reaching and on the top outwardly bent guide sheets 7, which serve the insertion of the packing casings to be filled. Finally on the upper side of the plate 1 guide members 8 standing erected in the comer ranges in form of studs or the like are provided which extend through the already described perforations 15 in the bottom of the packing case.
  • the central guide member 4 in the center of the plate 1 carries on its upper side by example six guide ledges 9 which form an angle of degrees relative to each other.
  • the guide member 4 is only required then, if the packing casing has a center opening 16.
  • the packing casing according to FIG. 2 is mounted on the device according to FIG. 4, which is disposed on the filling machine.
  • the packing casing is inserted with its bottom pointing downwardly from above between the resilient feed sheets 7.
  • the cover ledges 12 are thereby brought into engagement with the outside of the side parts 10 and retained by the guide sheets 7 in this position, so that the cover flaps 12 do not prevent the filling of the individual packings 17.
  • the guide members 8, which are here formed by example, pin like enter through the perforations 15 at the bottom flaps 13, so that they project in the inner space of the packing casing. Now the conventional piling up of the individual packings on the filling machine can take place.
  • the individual packings 17 are brought into the packing container thereby one after another in the manner shown in FIG. 7, whereby four of the soft packings engage with their setting edge on the corresponding guide member 8, while the remaining two individual packings 17 are supported by the wall for the side parts 10, respectively, of the packing case.
  • the individual packings 17 are guided in the center of the layer formed by six individual packings through the pyramid shaped cover 4.
  • the individual packings 17 are mounted with their points between the guide sheets 9. It is, however, understood, that instead of the pyramid shaped cover 4 of the device also a separate cover supported by example, by the container bottom can be used. During the piling up, one individual packing adjusts tightly to the other. Each individual packing 17 is safely retained in its relative position to the other individual packings 17 of one layer. A displacement of the tetra-hedron-shaped soft packing is not possible.
  • the packing casing can have even a square ground face, in spite of the fact, that only the key width of a regular hexagon and the distance of two oppositely disposed edges are not equal.
  • the guide studs 8 reaching into the inner space of the packing casings take care of the fact that the individual packing to be inserted with its outside obliquely to the wall of the casing assumes the right position to the remaining individual packings as this is indicated in principle by example, in FIG. 10.
  • the individual packings 17 can then further individual packings be piled up in the formed triangular space, so that finally a collection packing is formed in which the individual piled up packings retain each other and support each other, without collapse of the pile.
  • the individual packings 17, if at all, can be displaced only slightly and uniformly, since the guide members 8 are no more present.
  • the cover ledges 12 are freed again, so that the filled container can be closed in conventional manner.
  • FIG. 8 a top plan view on the erected non-filled packing casing in accordance with FIG. 3 is disclosed. It is apparent how in the corner ranges of the bottom flaps 13 and 13' or of the packing casing, respectively, a protection flap 18 for the passing through of the guide members 8 are disposed. The protection flaps 18 bring about a perforation in the center range, which perforation is determined for the insert of the guide member 8. It is to be understood, that the bottom flaps l3 and 13' can be glued together such, that a flap folding capacity of the packing container and the erection thereof from the flap folded position is made possible.
  • FIG. 9 a section through the packing casing of FIG. 8 is disclosed, whereby the guide members 8 and 4 are indicated.
  • a position has been chosen in which the first individual packing 17 is stored in the packing casing. It is visible how the protection fiap 18 is protectingly disposed between a setting edge 20 of the individual packing 17 and the guide member 8, while the individual packing 17 is retained at the other end by the guide member 4.
  • the guide members 8 and 4 guide and support the individual packings 17 at least so long, until all six individual packings which belong to one layer are deposited in the packing case.
  • the guide members 8 and 4 can of course remain so long in the packing container, until the latter is completely filled up.
  • FIG. 10 shows the device in accordance with FIG. 4 on which the packing container in accordance with FIGS. 2 or 5, respectively, are mounted, whereby the lower most layer of six individual packings 17 is stored.
  • Four of the six individual packings 17 support themselves with their setting edges 20 on the guide members 8.
  • FIG. 1 1 a further formation possibility of the packing container in accordance with the invention is disclosed.
  • This packing container or casing has a rectangular ground face which approximately corresponds with the measurement of the regular hexagon, whereby, however, also the length of the side walls can be slightly shortened or extended, respectively.
  • a pyramid shaped setting face 21 is provided, which has six supporting faces for the six individual packings 17.
  • the pyramid-shaped setting face 21 can by example, form by particular folding and formation of bottom flaps or can consist also of a separate insertion bottom as it is known.
  • Essential is here, that here also the protection flaps are cut, the bending lines 19 of which are disposed parallel to the setting edges 20 of the individual packings 17.
  • the protection flaps 18 have here a longitudinal design in order to guide and retain the setting edges 20 on a longer stroke. It is as a matter of course also possible, by the perforation 15 formed by the protection flap 18 to feed through two guide members 8. In a variation, finally also each protection flap 18 can be subdivided. As much as the bottom parts overlap each other in the range of the protection flaps 18, is merely necessary, to provide a protection flap 18 in a bottom flap, while the other bottom flap can carry at the corresponding point a stamping out.
  • a packing casing formed of a folding cardboard blank with rectangular, in particular square crosssection for reception therein of tetrahedron-shaped individual packings, in particular soft packings, comprising a blank including bottom-and cover-flaps,
