Definitions

  • Stable tubular bags process for their manufacture and device for carrying out the process
  • the invention relates to a method for the production of stable tubular bags for holding fillings, which are formed from a flat material with two side walls, two side seams, a reclosure element, a bottom, a head part and a pouring spout with head seams and a closure seam, and a device to carry out the procedure.
  • tubular bags for the packaging of filling goods in different areas of the food industry or in the area of materials.
  • bags with pouring spouts are known, into which a foldable foil element is inserted in the upper region of their side walls, which is inserted between the side walls and welded to the side walls.
  • a removal opening for filling material is provided through a grommet of the film element.

  • Such bags have the disadvantage that they have to be manufactured in several very complex process steps.
  • the document DE 38 24 753 AI relates to a reclosable bag which is formed from a film web and has a longitudinal and bottom transverse seam and an upper, tightly sealed transverse seam which can be torn open for emptying the bag. Another transverse seam is below the transverse seam
  • CONFIRMATION COPY arranged, in the area of which interlocking closure elements are provided, by means of which the bag can be reclosed.
  • the interlocking closure elements are applied to the unfolded part of the film web.
  • the disadvantage is that the bags are intended for use in outer packaging, so they do not have an independent stability.
  • Another disadvantage is the fact that the closure elements are applied separately and in segments to the film web.
  • a stand-up pouch is described which has two side walls which form essentially rectangular surface parts which are sealed to one another at their longitudinal edges. Surfaces are folded in at the lower and upper transverse edges. The lower transverse edge is designed as a stand.
  • a spout is inserted into the upper surface as a removal opening. The insertion of the spout requires a complex separate process step with a prefabricated spout.
  • the invention has for its object to provide a method and an apparatus for producing a stable tubular bag with a pouring spout for dispensing contents in the tubular bag and an inserted reclosing element, which is easily and inexpensively manufactured from a flat material without pre-cut from a piece and can be filled quickly with differently designed contents.
  • the object is achieved in that, according to the method for producing tubular bags, the tube is formed from a flat material via a shaped shoulder and a shaped collar surrounding a shaped tube, the two edge regions of the flat endless material being placed against one another to form a vertical, wide overlap, so that the wide overlap extends laterally from the form fill pipe transverse to the direction of advance of the sheet material and is moved parallel to the form fill pipe.
  • the shape of the filling tube can be round, square or oval in cross section.
  • the pouring spout is shaped according to the invention in such a way that the wide and areal overlap is punched out to form a pouring spout and at the same time the edge regions of the pouring spout thus formed with head seams and a closure seam as an outer boundary the pouring spout can be closed permanently.

  • the closure seam can only be sealed so that the closure seam is closed airtight, but can be opened again in the area of the pouring spout by simultaneously pulling the folded-in head wall and the opposite tubular bag wall.
  • the reclosing element is inserted and fastened on the flat material in a continuous strip, running from a supply roll, along the feed direction of the flat material, within the region of the later wide overlap of the edge regions of the formed flat material. It is particularly advantageous if the reclosing element, which can be designed as a force-fitting pair, is applied to the flat material in a coherent pair.
  • the resealable element can also be sealed or glued to the sheet material in sections and also as a separate pair.
  • the invention is advantageously embodied in that the tubular bag head part is formed by folding in a surface of a side wall with a head fold-in and, after a short time thereafter, the tubular bag bottom is formed by folding in a surface of a side wall with a base fold-in by means of folders located laterally from the mold filling tube.
  • the pre-formed transverse tubular bag is closed with a lower side seam by means of a transverse welding and separating device from the head part to the floor, after which the tubular bag is filled through the molded tube via an upper still open side of the tubular bag and then closed on the upper side with a side seam by means of a cross welding and separating device, continuously from the head part to the floor.
  • the filled tubular bag is separated from the preformed flat material.
  • the lower side seam of the subsequent tubular bag is formed.
  • the filling of the tubular bags via their open upper side allows a larger filling opening and thus the use of form filling tubes which have a larger throughput than form filling tubes which are used for the filling of tubular bags at the top.
  • the choice of a larger inner diameter enables the tubular bag to be filled quickly.
  • the largest possible inside diameter of the filling pipe opening is advantageous, especially if the filling material is to be passed through sieves.
  • the invention receives a meaningful design in that when the head seams are welded in the top seam edge areas, the reclosure element is firmly incorporated and, at the same time, the reclosure element remains detachable in the area of the base of the pouring spout as an output area and can be opened and closed for dispensing filling material. It is in the broader sense of the invention if the tubular bags are produced by the method according to the invention without inserting the reclosable elements. In this case, the head seams are closed directly without interposing the reclosing elements, in that the flat material is placed directly on top of one another in the edge area of the head seam and welded.
  • the invention is designed if a flat, continuous film web is used as the flat material.
  • the film web can advantageously be a weldable single-layer plastic film, a weldable laminated multilayer film or a weldable coextruded multilayer plastic film.
  • a further advantageous embodiment of the method can be seen in the fact that at least one stiffening line is introduced transversely to the direction of advance of the flat material in the flat material running continuously from a supply roll, these stiffening lines, which lead to the improvement of the stability of the tubular bag, also lengthways or at an angle can be introduced to the feed direction of the flat material. Likewise increase the stability of the tubular bag by means of fold-in corner edges in the bottom and in the head part.
  • the flat material is sterilized and further processed in the subsequent process steps under a sterile atmosphere until the filled and closed tubular bag is separated.
  • the sterilization takes place by means of the finest distribution of droplets of a liquid sterilizing agent under corona discharge.

Abstract

Cette invention concerne un procédé pour la fabrication de sachets tubulaires résistants, réalisés à partir d'un matériau plat (22) d'une seule pièce sans partie découpée au préalable, et possédant un élément (3) permettant de refermer le sachet, un bec verseur (4) avec des joints de tête (6) et un joint d'arrêt (5), un fond plié et une partie supérieure pliée (17). L'invention concerne également une ensacheuse verticale pour la mise en oeuvre dudit procédé. Lors de la fabrication du sachet tubulaire, la formation du sachet à partir du matériau plat (22) est effectuée au moyen d'un épaulement de formage (28) et d'une collerette (29) enveloppant le tube de formage (23). Les deux bords du matériau plat sans fin sont largement superposés verticalement, de manière à ce que la large zone de superposition, située le long du tube de formage (23), soit disposée obliquement par rapport à la direction d'avancement du matériau plat, et puisse être déplacée parallèlement au tube de formage (23). Le formage du bec verseur (4) est réalisé de façon à ce que la large zone de superposition plate soit découpée en forme de bec verseur, et que les bords du bec verseur ainsi formé soient fermés de façon indétachable par des joints de tête (6) et un joint d'arrêt (5), pour former la limite extérieure du bec verseur.
