Abstract

Process for producing prism-shaped containers without side-projections and with level gable-shaped surfaces as the closure ends, using a continuously fed tube of flexible material filled with a liquid substance, whereby the lateral regions (2, 4, 2', 4') connected to the transverse sealing strips (5, 5') are slid inside the tube (1, 1') before the actuation of the transverse flattening mechanisms, in this way the formation of unattractive projecting side-pieces on the closure surfaces is avoided.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von prismatischen Behältern ohne seitliche Ohren nach dem Oberbegriff des einzigen Anspruchs.The invention relates to a method for producing prismatic containers without lateral ears according to the preamble of the single claim.

Ein derartiges Verfahren ist aus der US-A-3 263 391 bekannt. Das Rohr aus biegsamem Material wird dabei nicht kontinuierlich zugeführt, sondern schrittweise.Such a method is known from US-A-3,263,391. The pipe made of flexible material is not fed continuously, but gradually.

Es sind bereits Maschinen zum Verpacken von flüssigen Substanzen in Behältern aus biegsamem Material bekannt. Diese Behälter haben die charakteristische Parallelepipedform mit unschönen und unbequemen seitlichen Ohren, welche an das Äußere des Körpers der Behälter gebogen und dort befestigt sindMachines for packaging liquid substances in containers made of flexible material are already known. These containers have the characteristic parallelepiped shape with unsightly and uncomfortable lateral ears, which are bent to the outside of the body of the container and attached there

In den Anlagen zur Herstellung derartiger Behälter wird ein ebenes Band aus biegsamem Material von einer Spule zugeführt und um ein in Längsrichtung geschlossenes und mit dem zu verpackenden flüssigen Material ständig gefüllten Rohr gewickelt.In the systems for the production of such containers, a flat strip 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 packed.

Diese bei einem bestimmten Flüssigkeitsdruck kontinuierlich arbeitenden bekannten Anlagen sind an sich aseptisch und daher zum Verpacken von sterilen Substanzen ohne Berührung mit der atmosphärischen Luft besonders geeignet. In den mit diesen Anlagen gefüllten und verschlossenen Behältern ist kein Polster aus Außenluft eingeschlossen.These known systems, which operate continuously at a certain liquid pressure, are inherently aseptic and are therefore particularly suitable for packaging sterile substances without contact with the atmospheric air. No outside air cushion is enclosed in the containers filled and closed with these systems.

Es sind weitere Arten von Verpackungsmaschinen bekannt, bei welchen die zu verpackende Flüssickeit in aus Karton geformte Schachteln gefüllt wird, deren Öffnung anschließend in der charakteristischen Form einer Haube mit zwei Giebelflächen versiegelt wird. Diese nicht bei einer bestimnten Höhe des Flüssigkeitsdruckes arbeitenden Verpackungsmaschinen schließen zwangsläufig im Behälter ein Polsrer aus Außenluft ein. Darüber hinaus ist für ein aseptisches Vorgehen dort die Verwendung eines unter Druck gesetzten Tunnels erforderlich; folglich wird im Behälter zwangsläufig ein Polster aus steriler Luft eingeschlossen.Further types of packaging machines are known in which the liquid to be packaged is filled into boxes made of cardboard, the opening of which is then sealed in the characteristic shape of a hood with two gable surfaces. These packaging machines, which do not operate at a specific level of liquid pressure, inevitably include a cushion made of outside air in the container. In addition, the use of a pressurized tunnel is required for an aseptic procedure; consequently, a cushion of sterile air is inevitably enclosed in the container.

Aus der DE-B-1 146 431 ist eine Maschine zum kontinuierlichen Herstellen gefüllter und verschlossener Einzelpackungen mit parallelepipedischer Form bekannt, bei dem zur an sich bekannten Vorprägung einer zu einer Packung umzuformenden Folienbahn zwischen der Vorratsspule und dem hohlen Formdorn zwei Prägewalzen angeordnet sind, durch die in die Folienbahn sowohl die Längsals auch die Querverschlußfaltlinien eingeprägt werden.From DE-B-1 146 431 a machine for the continuous production of filled and closed individual packs with a parallelepiped shape is known, in which two embossing rolls are arranged between the supply reel and the hollow mandrel for the pre-embossing of a film web to be formed into a pack, which is known per se which are embossed in the film web, both the longitudinal and the cross-fold lines.

Aus der CH-A-412 685 ist ein Verfahren zur Herstellung von mit Flüssigkeiten gefüllten Quaderpackungen aus einem durchgehenden Schlauch bekannt, in den das Füllgut unter Bildung eines Füllspiegels eingebracht wird. Die dabei hergestellten Behälter haben allerdings am oberen Ende nicht die Form einer Haube mit zwei Giebelflächen.From CH-A-412 685 a method for the production of cuboid packs filled with liquids from a continuous tube is known, into which the filling material is introduced with the formation of a filling level. However, the containers produced here do not have the shape of a hood with two gable surfaces at the upper end.

Aufgabe der Erfindung ist es, das eingangs angegebene Verfahren zur Herstellung von prismatischen Behältern ohne seitliche Ohren zu verbessern.The object of the invention is to improve the method specified at the outset for producing prismatic containers without lateral ears.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des einzigen Anspruchs angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of the single claim.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. Es zeigt:

  • Fig. 1 eine schematische perspektivische Ansicht des vollständig mit einer flüssigen Substanz gefüllten, quer abgeplatteten, versiegelten und durchgeschnittenen kontinuierlich zugeführten Rohres aus biegsamem Material, und
  • Fig. 2 eine perspektivische Ansicht des Behälters mit abgeplattetem unteren Ende und mit in Form einer Haube mit zwei Giebelflächen ausgebildetem oberem Ende.
An embodiment of the invention is explained below with reference to the drawing. It shows:
  • Fig. 1 is a schematic perspective view of the completely filled with a liquid substance, transversely flattened, sealed and cut continuously fed tube made of flexible material, and
  • Fig. 2 is a perspective view of the container with a flattened lower end and formed in the form of a hood with two gable surfaces upper end.

Aus Fig. 1 ist zu ersehen, daß seitliche Zonen 2, 4, 2′, 4′ durch nicht dargestellte bekannte Organe zum Inneren eines Rohres 1 geschoben werden, um das Abragen von dreieckigen Ohren, welche sich durch das Abplatten des Querversiegelungsstreifens 5 ergeben würden, zu vermeiden.From Fig. 1 it can be seen that lateral zones 2, 4, 2 ', 4' are pushed by known organs, not shown, to the inside of a tube 1 to the protrusion of triangular ears, which would result from the flattening of the transverse sealing strip 5 , to avoid.

Die Enden des Behälters weisen demnach dreieckige Zonen 2, 4, 2′, 4′ auf, welche unter die Giebelflächen 3, 3′ gelegt sind. Der Behälter weist an jedem Ende zwei Giebelflächenauf. Diese Giebelflächen 3, 3′ können anschließend angelegt werden, so daß sie senkrecht zu den Seitenflächen des Behälters 1 verlaufen.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 are perpendicular to the side surfaces of the container 1.

In Fig. 2 ist der Behälter 1′ mit dem abgeplatteten oder angelegten Boden und dem oberen Ende in der charakteristischen Form einer Haube mit zwei Giebelflächen dargestellt.In Fig. 2 the container 1 'is shown with the flattened or applied floor and the upper end in the characteristic shape of a hood with two gable surfaces.

Dieser Behälter 1′, welcher bei einem bestimmten Flüssigkeitsdruck versiegelt worden ist, weist im Inneren kein Luftpolster auf.This container 1 ', which has been sealed at a certain liquid pressure, has no air cushion inside.

Das erfindungsgemäße Verfahren kann mit Verpackungsmaschinen beliebigen Aufbaus durchgefürt werden. So beispielsweise mit Verpackungsmaschinen mit vertikaler Anordnung, bei welchen ein oder mehrere Versiegelungsteile von intermittierenden Kurbeltrieben oder Förderbändern in kontinuierlicher Bewegung ausgebildet werden. Es kann auch mit Verpackungsmaschinen mit horizontaler Anordnung über ein horizontales Rad angebrachten Versiegelungsteilen bei kontinuierlicher Drehung durchgeführt werden.The method according to the invention can be carried out with packaging machines of any construction. For example, with packaging machines with a vertical arrangement, in which one or more sealing parts are intermittent Crank drives or conveyor belts are designed in continuous motion. It can also be carried out with packaging machines with a horizontal arrangement of sealing parts attached by means of a horizontal wheel with continuous rotation.

Ferner kann das erfindungsgemäße Verfahren in Verpackungsmaschinen mit einer oder mehreren einzeln gespeisten und iintermittierend betätigten Stationen durchgeführt werden.Furthermore, the method according to the invention can be carried out in packaging machines with one or more individually fed and intermittently operated stations.

Wesentlich ist, daß die verwendeten Verpackungsmaschinen mit einem bestimmten Flüssigkeitsdruck arbeiten, wobei die strukturelle und funktionelle Anordnung gleichgültig ist, sofern sie geeignet sind, Behälter mit zwei Giebelflächen an den Enden und ohne Luftpolster im Inneren zu erzeugen.It is essential that the packaging machines used work with a certain liquid pressure, the structural and functional arrangement being indifferent, provided that they are suitable for producing containers with two gable surfaces at the ends and without air cushions inside.
