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. It is also conceivable first place the closing element on the free end face of the mandrel and only then pull the tubular container open on both sides onto the mandrel. 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.
- the ferritic coating of the mandrel head is arranged.
- a very thin metal plate can also be provided, which can be heated electrically by means of a current pulse. 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.

- Fig. 14 is a plan view of the device of Fig. 13 in
- FIG. 1 shows an upper part, based on the later use position, of a container, generally designated 1, which consists of a container blank 2 made of paper material coated on both sides with PE, which is partially shown in FIG.
- the container wall 3 which is unfolded tubularly and connected along a seam 9, has in the upper region a correspondingly circumferential edge folding line 4, above which the four sides involved in the closure lie, namely a spout side 5, from which a spout is formed when the closure is opened can be a rear neighboring side 6, a front neighboring side 7 and a side 8 opposite the pouring side 5, along which the seam 9 runs.
- a spout side 5 from which a spout is formed when the closure is opened can be a rear neighboring side 6, a front neighboring side 7 and a side 8 opposite the pouring side 5, along which the seam 9 runs.
- Edge folding line practically embossed triangular folding lines 11. Corresponding fold lines
- the container blank 2 in Fig. 7 shows that the pouring side 5 is longer than the opposite side 8, so that the conditions shown in FIG. 2, for example, result later when folding.
- the upper edge of the neighboring sides 6, 7 also has a profile that rises to the pouring side 5.
- An air outlet opening 14 is created when the closure is opened, which is shown in FIG. 10 and is intended to facilitate the inflow of air when liquid flows out of the container 1.
- a pull tab 20 is already glued to the inner surface of the pouring side 5, which, when the container 1 is closed at its upper opening 10, assumes the position shown in FIGS. 2 and 3, for example, so that it opens the container is easy to pull up.
- a closure element which is shown in different forms in FIGS. 4, 5 and 6 and is generally designated 15 is to be integrated into the closure. It consists of a piece of PE film as a square 16 according to the figure
- edges 31, 32, 33, 34 of the inner surfaces of the sides 6, 7, as shown in FIG. 3, are connected in an absolutely sealing manner to the respectively adjacent inner surfaces of the two sides 5, 8.
- the closing element 15 covers the square inner surface of FIG upper end of the container. As will be explained below, narrow edge strips of the inner surface can possibly remain free if the corners of the inner surface are otherwise closed and sealed, as will be explained. If the closing element 15, irrespective of whether the embodiment according to FIG. 4, 5 or 6 is selected, is glued in this way, the triangular regions of the sides 5, 6, 7 and 8 which are exposed inside the container become (see FIG. 3 ) mechanically fixed and sealed together along the edges 31, 32, 33, 34.
- the opening 10 is expediently closed in the following steps:
- FIG. 7 shows a fold line pattern of a development of the container with vertical hatching.
- the activated areas are the lower tips of the hatched triangles.
- the neighboring pages 6, 7 are then folded first along their oblique fold lines 12 and folded inwards along their edge fold lines 4. This is followed by folding of the side 8 opposite the pouring side 5, whereupon the pouring side 5, as the last of the four sides, is folded over along the edge folding line 4 and folded with the arcuate edge 13 and the pull tab 20 onto the outer surface of the opposite side 8.
- the heated closing element 15 is pressed and glued from the inside of the container onto the inner surface of the front side of the container, as shown in FIG. 3, so that the image according to FIG. 8 is obtained.
- the activated corner areas E are also pressed together and glued to seal the four corners. As I said, the corner areas and if necessary. generally the edge strips of the inner surface of the container end face not to be covered with the closing element 15 when the corners are first glued in a sealing manner.
- the status according to FIG. 8 results in the course of the method - possibly with the release of edge strips all around - where the closing element 15, by connecting the edges 31, 32, 33, 34 to the adjacent surface areas, the gaps or spaces present there closes slot-shaped openings in a sealing manner and at the same time firmly connects the four sides 5, 6, 7, 8 to one another from the inside of the container.
- the pull tab 20 is expediently glued onto the outer surface of the side 8 during the production of the adhesive bond or at another time so that it lies as flat as possible on the outer surface of the side 8 during transport.
- the container 1 After filling in a liquid and after closing the bottom of the container 1 in any conventional manner, the container 1 reaches the store and from there to the consumer, who opens the container 1 again.
- the pull tab 20 is easily released from the side 8 with two fingers and the spout side 5 is pulled up with it.
- the triangular inner surface (cf. FIG. 3 or 8) of the pourer side 5 progressively tears along the edges 31, 32 from the center outwards from these inner folded edges of the two neighboring sides 6, 7. Only this tearing off of the inner folded edges 31, 32 of the neighboring sides 6, 7 consequently forms the pull-up resistance, which is thus easy to overcome.
- the folded surfaces are namely only in the Corner areas glued together and otherwise lie unglued on top of each other.
- a spout 30 can easily be formed, as shown in FIGS. 9 and 10, by correspondingly folding the spout side 5 along the oblique fold lines 11.
- air outlet opening 14 air has easy access to the interior of the container, so that the liquid can flow out is not hindered from the container 1.
- the pull tab 20 can easily be torn off from the pourer side 5, so that it does not form an obstacle when pouring the liquid out of the pourer 30.
- FIGS. 9 and 10 illustrate the shape of the opened container and, in particular, of the spout 30, both from the inside of the container (FIG. 9) and from the outside when looking at the upper part of the container.
- the mechanical production of the closure can proceed as follows:
- a multi-armed rotor is arranged in a machine system for processing the container blanks for filling and closing the containers, which rotates driven in cycles and closes the upper opening when the container is in use in a sealing manner during a revolution.
- the container unfolded in tubular form is in each case drawn in a lower angular position onto a correspondingly square mandrel which corresponds in cross section to the container blank.
- the corner regions of the sides forming the opening of the container are now activated.
- the four sides in the manner described is folded on top of one another, and now the likewise activated closing element made of PE film is guided to the inside surface of the container front side and pressed there firmly, the folded sides being held on the back by corresponding counterpressure.
- the closing element is firmly and sealingly adhered to the inner surface of the container front side.
- the process of activating the corner areas of the triangular surfaces and folding the sides can, as already stated above, take place in reverse order. In any case, the closure is finished after the closing element has been glued into the container.
- the container can now be removed from the mandrel and automatically transported to fill the liquid.
- FIGS. 11 and 12 or 13 and 14 Two devices for activating or heating and gluing the closing element 15 made of PE film during the above-described work cycle are shown in FIGS. 11 and 12 or 13 and 14.
- the head 38 of the mandrel on which the container 1 is received is made of ceramic or plastic, in any case from an electrically insulating material.
- the end face 39 of the mandrel head 38 is provided with a coating 40 made of ferritic metal with a thickness of approximately 20 ⁇ m, which in turn is covered with a PTFE skin 41.
- the surface of the PTFE skin 41 forms a receiving surface 42 for the closing element 15.
- the mandrel head 38 is opposite a press ram 43, in which an induction coil 44 is arranged and provided with a corresponding power supply .
- the closing element 15 is placed on the receiving surface 42 of the PTFE skin 41 and held in place by means of negative pressure, which is effective via bores 45 in the end region of the mandrel head 38 which can be subjected to negative pressure.
- the closing element 15 consisting of PE film 15-20 ⁇ m is now heated by the inductive heat generated in the coating 40 made of ferritic metal, whereupon the The ram 43 is guided further against the mandrel head 38 and the end faces of the container 1 and the closing element 15 are compressed between the lower surface 47 of the ram 43 and the receiving surface 42 such that the heated and activated closing element 15 is firmly attached to the likewise activated one PE coating of the inner surface 37 of the end face of the container 1 sticks. After removing the press ram 43 from the mandrel head 38, the closing element 15 is glued sealingly in the container ter 1.
- the head 52 has a shaft 60 at the bottom which can be inserted into a bore 61 and there by means of screws
- the head 52 can be quickly replaced.
- a heater 59 is arranged in the plate 50 in order to maintain the PTFE-coated end face of the plate 50, which forms the receiving surface 57 for the closing element 15, at a temperature level with which a closing element 15 placed on the receiving surface 57 can be made so largely to soften or made sticky that it is glued to the end-side inner surface 37 of the container 1 under appropriate pressure (press ram not shown).
- the closing element 15 placed on the receiving surface 57 can be held in place by means of bores 56 in the plate 50 which can be subjected to negative pressure.
- this second heating and pressing device and also the work cycle that can be carried out by gluing in the closing element 15 is similar to that in the case of the above-described first heating and pressing device, so that a further description is dispensed with.
