Definitions

  • the invention relates to a method and a device for closing
  • Closing an opening of a tubular container which is intended in particular for liquids and consists of paper or cardboard material which is at least sealed on one side, with an opening wall which, in the region of the opening of the container to be closed, is separated from the container by one or more edge fold lines Wall is divided and surrounds the opening of the container all around, to form a closure along the edge fold lines inwards and on top of each other and glued together in areas and the bond can be released by later pulling up the closure by pulling up at least parts of the opening wall.
  • the invention has particular relevance for a method and the device used in this case, in which the opening wall consists of four sides, which are separated from the container wall by square edge folding lines in the region of the opening of the container to be closed and surround the opening of the container all around , to form a closure along the edge folding lines and a triangular pattern of oblique folding lines on the sides, inwards and on top of one another and glued to one another and when opening the closure later by pulling up and, if necessary, detaching the adhesion of one side, a spout is formed from this side can.
  • the invention relates to a closure which is to be used in the context of the aforementioned methods.
  • a method for closing an opening of a tubular container made of paper material is known from the document EP-Bl-162883, from which a corresponding closure also emerges.
  • This closure which is produced according to the process summarized at the beginning, has considerable advantages over other containers or packaging for liquids, in particular for milk, fruit juices, etc., such as ease of manufacture in the automated production process, good material utilization through suitable shapes for the carton or Paper cutting of the container blank, low container weight in relation to the liquid volume, optimal stackability and space utilization during storage and transportation as well as for storage by the consumer, but above all very good handling when opening the closure and when pouring out the liquid.
  • the closure is made with the container still empty and with the bottom still open, then the container is filled in the opposite position and only then is the top opening of the container now closed in a conventional manner, so that a total Cube-shaped container is created.
  • the invention has for its object to further facilitate the manufacture and handling of the closure, but above all to produce a liquid-tight closure in a simple and reliable manner with the simplest possible means.
  • Adhesive layer can be formed, are glued to one another, in particular the inner edges of the regions first folded inwards are sealingly connected to the adjacent regions by the closing element in such a way that at least the region or regions which are opened when the closure is opened are torn up by tearing the closing element along the corresponding inner edges are detachable from the neighboring areas.
  • the solution for the method which was named second at the outset is that the sides in the folded-on position are glued in from the inside of the container by at least one film-like closing element which can also be applied or sprayed on or the like.
  • an adhesive layer can be formed, are glued to one another, in particular the inner edges of the pages folded first inward are connected by the closing element to the adjacent areas of the later folded pages in such a way that at least the first pulled up side when the closure is opened by tearing the closure ⁇ element along the corresponding inner edges of the neighboring sides is detachable.
  • the second method is a rectangular container, or at least a container with a rectangular cross section, while the cross section in the first method is practically arbitrary.
  • the invention can be used equally for both methods, because the core idea of the invention is to glue a film-like closing element to the inner surface of the closure-side end face of the container, which closes the exposed edges and the adjacent ones Surfaces are connected to one another in such a way that the closure can be produced, namely by sealingly connecting the opening wall parts or the folded sides of the opening to one another without gluing surface to surface.
  • the four sides - in the case of a cuboid-shaped container - for closing the later pouring opening - are of course self-evident at. open container base - folded on top of one another, and in this position the sides folded onto one another are connected to one another from the inside, that is to say from the inside of the container, by gluing or gluing a film-like closing element.
  • an adhesive layer can also be formed by spraying on a suitable adhesive, which connects the adjacent edges and surfaces with one another in such a way that the unwanted unfolding of the folded-up wall parts or sides cannot take place and, above all, the closure is absolutely liquid-tight , because it covers all areas or gaps, openings, slots or the like, through which liquid can accidentally penetrate to the outside.
  • this film-like closing element or the adhesive layer can easily tear correspondingly along the edges of the side when the closure is opened by the consumer, which is the first to be unfolded when the container is opened.
  • the invention thus provides a mechanically high-strength closure and an absolutely liquid-tight sealing of the closure without the opening of the closure being impeded or made difficult by the consumer.
  • the closing element means that only the folded edges of the pages that are first folded inwards, which form triangles with a rectangular container cross section, are included the adjacent areas of the sides subsequently folded onto these triangles in a sealing manner. As a result, the side that later forms the pouring opening can easily be detached from the closure and simply folded up. The areas of this spout side that are folded onto one another and onto the underlying sides are not glued to one another.
  • the other folded edges should also be releasable if other sides of the container opening are pulled up and unfolded.
  • a pull-open tab which is known per se, is preferably used to easily open the closure.
  • the method according to the invention provides an optimal solution to the above problem.
  • a closing element made of sealable film or of a material coated, for example, with a film that is sealable on at least one side, is used and glued to the closing element by heating the closing element and pressing the inner container surfaces to be locked.
  • the welding of such a closing element The outer coating of the container sides can be carried out in production with relatively simple means and at a very high speed and in a reliable manner.
  • the shape of the film-like closing element is arbitrary as long as the function of the closing element is guaranteed.
  • the entire inner surface of the closure-side end face of the container is grasped with the closing element, but at least the edge areas, for connecting adjoining areas or sides.
  • the corners of the inside of the container are first sealed, preferably by heating and pressing, and the remaining areas are sealed by gluing in the closing element, a closing element having a smaller area than the size of the inside of the container being used can be.
  • a closure according to the invention for closing an opening of a tubular container which is intended in particular for liquids and consists of paper or cardboard material which is at least sealed on one side and is manufactured by one of the two known processes mentioned at the outset, is characterized according to the invention that on the inner surface of the closure-side end face of the container, which is formed by the internally exposed areas of the opening wall or sides folded onto one another, a film-like closing element which can be severed when the closure is opened by pulling up at least part of the opening wall or the sides, the can also consist of an applied adhesive layer, glued to the inside of the container in a sealing manner is.
  • a closure produced in this way which can be produced by various and arbitrary methods, ensures an absolutely liquid-tight closure of the later pouring side of the container from the inside of the container, that is, at. still open container bottom, without the folded-together surfaces of the sides of the closure being glued to one another and thereby making it difficult to open.
  • the closing element made of PE film or PE-coated material onto the free end face of a dome, preferably a multi-armed rotor with corresponding Thorns at the outer end, placed there, heated and pressed against the inner surfaces of the four folded-up sides of the upper part of the container, that is to say against the inner surface of the upper part of the container.
  • the upper part of the container - preferably after activating the Corner areas - is folded over and the closing element is heated or already during the folding and is glued to this inner surface under pressure, which is exerted from the outside onto the front outer surface of the upper container part and from the inside with the mandrel onto the front inner surface of the upper container part becomes.

The result is essentially the same in both cases.
  • a device for heating and gluing the closing element, a device is therefore proposed according to the invention which is characterized in that the head of the mandrel consists of insulating material such as ceramic or plastic, the end face of which is coated with an extremely fine coating of ferritic material, the one with an anti-adhesive layer e.g. is covered with a PTFE skin, and that for pressing the end face of the container upper part against the end face of the mandrel head, on which the closing element can be placed, a press ram is provided, in which an induction coil for extremely brief inductive heating, e.g.

If necessary, the area of the mandrel head located below the ferritic coating or the plate can also be cooled in order to avoid heating to an undesirably high temperature level and thus to ensure the heating cycle - heating / cooling - with a short cycle time.
  • This device allows a very high number of working cycles by heating and gluing the closing element in a very short time. Since only the thin ferri- 'diagram coating on the end face of the mandrel head inductively or the thin plate is briefly electrically heated because of their ohmic resistance, and since the sec during a Schutaktdauer of, for example 0.4. Mediated heat immediately from which PE Existing closing element and film is removed from the adjacent inner surface of the upper container part or used for heating, there is practically a thermal or temperature vibration, in particular during the temperature peaks in the ferritic coating or
  • the press ram is pressed onto the front outer surface of the upper part of the container, the heated closing element, preferably the PE closing element, completely passes over to the inner surface of the upper side of the container and brings about the desired complete liquid-tight sealing of this inner surface.
  • Bores to which vacuum can be applied are preferably provided in the end face of the mandrel head to hold the closing element in place during heating, etc. It goes without saying that the duration of the negative pressure supply as well as the respective duration of action of the inductive or other heating must be precisely matched to the individual phases of the working cycle provided for gluing in the closing element.
  • a device which is characterized in that a plate which is heatable for heating the closing element and which is coated on the outside with an antiadhesive layer, for example with PTFE, closes off the end of the mandrel and the end face of the plate provides the receiving surface for the closing element and forms during gluing.
  • an antiadhesive layer for example with PTFE
  • the plate is easily interchangeable with a snap lock or other quick attachment.
  • a temperature level on the free end face of the plate is achieved and kept constant in this plate with a heater arranged in the plate, which at least brings about a softening of a closing element made of PE film placed on the plate.
  • the closing element can be pressed in the same way as an inductively heated closing element against the front inner surface of the upper container part and glued there in a sealing manner.
  • the PTFE coating of the plate which is preferably made of light metal such as aluminum, prevents PE film from sticking to the end face of the plate. After softening and pressing onto the front inner surface of the upper part of the container, the closing element, which is made of PE film, rather completely merges with this inner surface.

Abstract

Un procédé et un dispositif permettant de fermer une ouverture d'un récipient tubulaire, notamment de liquides, en papier ou en carton imperméabilisé au moins d'un côté. L'ouverture supérieure du récipient est fermée par pliage et collage des quatre côtés du récipient dans leur région supérieure. Pour que l'on puisse aisément ouvrir la fermeture en soulevant un de ses côtés, qui forme un bec verseur, et pour que les quatre côtés du récipient repliés les uns sur les autres soient mutuellement reliés de manière étanche, un élément pelliculaire de fermeture est collé sur la surface intérieure de la face frontale du récipient une fois que les quatre côtés du récipient ont été repliés les uns sur les autres, ce qui rend étanches surtout les bords libres de pliage des côtés du récipient, en les reliant fermement avec les zones limitrophes des côtés adjacents respectifs, sans collage des surfaces repliées les unes sur les autres. Lorsque l'on ouvre le récipient en soulevant un côté dit de versement de la fermeture, l'élément de fermeture est aisément sectionné le long du bord de pliage avec lequel le côté soulevé est relié, de sorte qu'il est possible d'ouvrir aisément la fermeture.
