Definitions

  • the invention relates to a process for the production of prismatic containers without lateral ears, with closure surfaces in the form of adjacent gable surfaces and with transverse sealing strips. From a continuously supplied tube made of flexible material and completely filled with a liquid substance.
  • Containers have the characteristic parallelepiped shape with unsightly and uncomfortable side ears, which are reminiscent of the
  • Exterior of the body of the container is bent and fastened there.
  • a flat band of flexible material is fed from a spool and wound around a tube which is closed in the longitudinal direction and is constantly filled with the liquid material to be packaged.
  • the invention is therefore based on the object, while eliminating the disadvantages known from the prior art, of creating a method for producing prismatic containers without lateral ears and with closure surfaces in the form of adjoining gable surfaces, with no air cushion inside the container is included.
  • This object is achieved in that the lateral zones connected to the transverse sealing strip before the intervention of transverse flattening elements. be pushed to the inside of the tube.
  • the lateral zones pushed towards the inside of the tube are brought under the resulting gable surfaces and under the transverse sealing strips.
  • FIG. 1 shows a schematic perspective view of the tube of flexible material which is completely filled with a liquid substance, cross-flattened, sealed and cut through and fed continuously
  • Fig. 2 is a perspective view of the container with a flattened lower end and with an upper end designed in the form of a hood with two gable surfaces.
  • lateral zones 2, 4, 2 ', 4' are pushed by known organs, not shown, to the inside of a tube 1 in order to protrude triangular ears which are caused by the flattening of the transverse sealing strip 5 would result to avoid.
  • the ends of the container accordingly have triangular zones 2, 4, 2 ', 4', which are placed under the gable surfaces 3, 3 ".
  • the container has two gable surfaces at each end. These gable surfaces 3, 3 * can then be created , so that they run perpendicular to the side surfaces of the container 1.
  • FIG. 2 shows the container 1 'with the flattened or laid bottom and the upper end in the characteristic shape of a hood with two gable surfaces.
  • This container 1 ' which has been sealed at a certain liquid pressure, has no air cushion inside.
  • the method according to the invention can be carried out with packaging machines of any construction.
  • packaging machines with a vertical arrangement in which one or more intermittent sealing parts Crank drives or conveyor belts are formed in a continuous Be ⁇ movement.
  • packaging machines with a horizontal arrangement of sealing parts attached via a horizontal wheel with continuous rotation can also be carried out with packaging machines with a horizontal arrangement of sealing parts attached via a horizontal wheel with continuous rotation.
  • the method according to the invention can be carried out in packaging machines with one or more individually fed and intermittently operated stations.
  • packaging machines used work with a certain liquid pressure, the structural and functional arrangement being irrelevant if they are suitable for producing containers with two gable surfaces at the ends and without air cushions inside.

Abstract

Procédé de production de récipients en forme de prisme, sans protubérances latérales et dotés de surfaces planes en forme de pignon servant d'extrémité de fermeture, dans lequel on utilise un tube d'un matériau souple, amené sans interruption et rempli d'une ssubstance liquide. Les zones latérales (2, 4, 2', 4') reliées aux bandes de scellement latérales (5, 5') sont passées dans le tube (1, 1') avant l'actionnement des mécanismes d'aplatissement transversal. On évite de cette manière la formation de protubérances latérales peu esthétiques sur les surfaces de fermeture.
