Definitions

  • the invention relates to a lace bag made mainly of conically rolled, foldable and bendable flat material, such as paper, metal foil, etc.
  • Such lace bags are generally used for packaging cone-shaped ice cream cones, for mechanical, thermal and hygienic protection thereof and for carrying advertising labels and pictures.
  • the object of the invention is to increase the thermal protection in the most economical manner and to maintain the other properties of the conventional lace bag. Another task is to produce a cone for a conical ice cream cone with an enlarged mouth area. In addition, the invention has the task of mechanical To increase the firmness of the lace bag where possible. Furthermore, the object of the invention is to provide a method for producing such cones and an apparatus for carrying out this method.
  • the invention provides a pointed cone of the type described at the beginning, which has at least one central region tapered with respect to the mouth region with folds running mainly in the longitudinal direction.
  • the folds preferably form rib-like, outward projections up to the lower region of the bag.
  • the folds are alternately directed inwards and outwards and form a zigzag wall.
  • One for packaging conical ice cream cones with an enlarged mouth area e.g. in the form of a hemisphere or a truncated cone with a conical shape which is suitable from that of the lower region, preferably has parts of different conical shape connected by a connecting region.
  • the upper mouth region of the pointed cone can either be conical, which is cheaper to manufacture, or can be regularly polygonal, which results in a somewhat greater strength.
  • a blank of flat material is preferably wrapped around a conical mandrel in a conventional manner and, in deviation from the known method, the conical lace bag obtained is deformed between an inner and an outer molded part over the entire circumference at the same time, the The inner wall of the lace bag is at least partially supported in a flexible manner becomes.
  • the original lace bag can be pushed onto the inner molded part by clamping, the pleating being obtained in accordance with the shape and position.
  • the radially movable inner molded part sections that can be used for this process can be spring-loaded outwards and preferably moved in and out in a controlled manner in the radial direction, so that no excessive friction occurs between the outer molded part and the cone during the deformation.
  • the invention relates to a device for producing a lace bag according to the invention, which is provided with inner and outer molded parts that can be moved in and out of each other, of which at least in the position moved into one another the outer or inner surface between them describe the shape of the deformed bag
  • at least the inner molded part is provided with radially movable molded part sections which extend mainly in the direction of the generatrix and are rotatably supported in the region of the cone tip of the molded part.
  • FIG. 1 and 2 show a lace bag according to the invention in a preferred embodiment in side view and in transverse. cut.
  • Two wall areas 2, 6 of different cone shape are connected by a connecting area 1.
  • the mouth region 2 has the same conical shape as the original pointed cone, indicated by broken lines 3, from which it is assumed.
  • folding 4 in the direction of the generatrix outward projections 5 or ribs are formed, which bring about a solidification of the piping bag and also serve to keep away from holding. Due to this pleating, the cone is tapered in the middle and lower area, so that appropriately shaped ice cream cones can be supported in it.
  • FIG. 3 shows how the folds are arranged in such a way that basement folds 7 are formed in the middle and lower region of the lace bag. Otherwise, this embodiment corresponds to that shown in FIG. 1.
  • Fig. 1 the mouth region is bluntly tapered, but can equally well be blunted pyramidal regularly.
  • coiled zigzag folds 10 are arranged only in the central area, where the lace bag is normally held, while the tip 11 and the mouth area 12 still have the original conical shape.
  • coiled means a configuration of the folds that differs from the generator.
  • FIGS. 5ab and 6ab A device suitable for producing the lace bag according to FIG. 1 is shown in FIGS. 5ab and 6ab.
  • the device has an inner and an outer molded part 14 and 15, respectively.
  • the outer molded part 15 has a conical cavity 16, corresponding to the lower region 6 of the deformed pointed cone, and a frustoconical cavity 17 connected to it by a step-shaped connecting region 18, corresponding to the upper region or mouth region 2 of the pointed cone.
  • grooves 19 are provided in the direction of the generating grooves, into which webs 20 arranged in corresponding slots 21 in the inner molded part 14 can be inserted radially outwards with play.
  • the webs 20 are each pivotally mounted on the underside at 23 in the inner molded part 14 and can be adjusted between an inner and an outer position (FIG. 5b left or right) by an axially movable control head.
  • a pointed cone this is placed on the inner molded part 14 with the webs 20 moved out and moved together with the same into the outer molded part 15.
  • the pointed cone is gradually tapered in the middle and lower region, while the rib-like projections 5 are formed between the gradually moved-in webs 20 and the grooves 19.
