Definitions
- the invention relates to a method according to claims 1 or 7 and a screw cap for carrying out this method according to claims 12 or 18.
- a screw cap which is screwed onto a threaded neck of a plastic bottle blown together with its closure end, thereby surrounding the closure end.
- the screw cap has at least one cutting tab formed on it, which, when screwed onto the threaded neck, slides elastically over a collar of the closure end and then springs radially inward under the collar.
- the cutting blade cuts through a radially arranged inside the federal transverse wall of the covenant and then lifted off the dissolved closure end and retains in the screw cap.
- This prior art does not relate to a container having a circular sealing surface having edge of his neck, on which edge a sealing film is applied hermetically sealing, which should be at least partially removed when opening the container. Furthermore, a reclosure of the bottle by re-screwing the screw cap is not possible.
- the object underlying the invention is now seen to provide a method and a screw cap for carrying out the method of the type mentioned , by a special seizing and peeling off the sealing film by hand after unscrewing the screw cap is unnecessary.
- This object is achieved in a method of the type mentioned above according to a first embodiment of the invention in that when unscrewing the screw cap from the neck, the sealing film from the outer periphery of the edge of the neck ago radially inwardly towards the central axis progressively solved by the screw cap at least partially and then lifted off the edge.
- the process of unscrewing the screw cap thus includes according to the invention, the release of the sealing film from the edge of the vessel or the bottle and possibly also the subsequent storage of the sealing film in the screw cap, which can be screwed on and unscrewed as often as usual, again until the container contents are exhausted by respective removal. Separate release of the sealing film by hand has become unnecessary.
- thermoplastic adhesive it is preferable to use induction welding for bonding the stiffening plate to the sealing film by using a thermoplastic adhesive as the adhesive.
- an adhesive for example, PE, PET, polyester or polystyrene or of a combination of these substances can be used as the adhesive on the surface of the stiffening plate facing the sealing film.
- a screw cap for carrying out the method according to the invention has a lid portion and a An internally threaded sleeve portion with a screw-on, for screwing on and unscrewing from an external thread of an edge having a neck of a bottle od.
- Hermetically sealed by means of a sealed to a circular sealing surface of the edge of the neck, possessing a radially projecting peripheral portion, sealing foil which is releasable and / or destructible to release a bottle contents.
- this screw cap and thus a first device solution of the above object is characterized by at least one between the internal thread and the lid portion on the sleeve portion along the inner circumference arranged in the starting position before screwing obliquely to the screw-in and out towards the center axis of the neck or the Screw cap-facing cutting blade, whose distance from the central axis before screwing is smaller than the outer diameter of the edge of the neck, and which is elastically deflected when screwing the screw cap on the neck of the bottle, the cutting blade with its cutting edge due to the pressure of the edge of the neck and the peripheral portion of the sealing film resiliently folds upwards and above the external thread and below the radially projecting peripheral portion of the sealing film, elastically deformed and resiliently biased towards the center axis, on the outer circumference of the neck for investment e comes as soon as the screwing is finished, and in that, when unscrewing the screw cap, the cutting edge of the severing knife is initially directed obliquely to the sealing foil
- the screw cap according to the invention triggers when unscrewing the od at the free edge of the neck of the bottle or the like.
- Sealed seal film in that the Abtrennmesser from the outside between the edge of the neck of the bottle and the sealing film, if necessary, to about the inner diameter of the neck out, gradually penetrates toward the center axis of the same and entrains the sealing film after loosening, since the separated sealing film is held between the separating blade and the lid portion.
- a plurality of individual, along the inner circumference of the sleeve portion distributed in the circumferential or rotational direction and fixedly connected to the sleeve portion separating blades are provided, which leave a clear width in planar radial position in the common plane in the region of the central axis, which has a lesser width Has diameter than the annular sealing surface, or as it has the outer diameter of the edge of the neck of the bottle od.
- the severing knife separates the sealing film only partially by its spiral cutting and causes its remaining lifting or tearing off simply by the further lifting of the peripheral region of the sealing film during further unscrewing and thus by the tension exerted on the sealing surface of the sealing film.
- each individual severing knife expediently has a cutting edge partially pointing in the unscrewing direction, which in each case causes the spiraling inward cutting into the sealing surface between the sealing film and the edge of the neck.
- Each cutting edge may advantageously be curved concavely and have a radially projecting, in Abschraubwindraum trailing tip cutting projection, which favors the penetration into the sealing surface.
- This deformation of the circumference of the sealing film on the one hand and the reinforcing plate, if present, on the other hand also favors the penetration of the or the severing knife in the gap between the sealing film and the edge, since the circumference of the sealing film and optionally the reinforcing plate forms an obliquely to the sealing film and to the central axis facing guide for the or the separating blade, such that the or the separating blade between the sealing film and the edge sliding and progressively unscrewing the screw more and more issuing in a horizontal cutting plane and thereby between the sealing film and edge to, if necessary, in the free space in the clearance of the neck penetrating the sealing film can completely replace or can.
- separating knife it can be formed circumferentially along the inner circumference of the sleeve section, ie as a ring knife.
- the elasticity of the material of the screw cap ensures the required deflectability of this ring diameter in the direction of the central axis.
- the described orientation of the or the separating knife (s) in his or her original position in which it or before screwing the screw cap on the neck of the container or the bottle obliquely to the screw-on and after pointing towards the central axis or pointing does not necessarily have to be so. Rather, the Knife alignment by the configuration of the knife shape on the one hand and the respective terminal on the sleeve portion along the inner circumference on the other hand also be taken so that the or the Abtrennmesser obliquely to the lid portion and inwardly towards the central axis has or point. In this case, the severing knife or the cut-off knife already essentially has the orientation that it or they need or need for the process of separating the sealing film from the neck.
- Adhesive and / or a sealing wax between the lid portion and neck is introduced, that when screwing the screw cap on the neck of the container, the intermediate layer is pressed by the inner surface of the lid portion on the sealing film, and that subsequently the inner surface is glued or welded to the surface of the sealing film such that the sealing film firmly adheres to the inner surface and that when unscrewing the screw cap from the neck of the container or the bottle, the sealing film is at least partially entrained by the screw cap.
- the respective container is thus completely or at least partially opened after unscrewing the screw cap, so that the contents can be removed.
- the sealing film within the clear width of the neck in the circumferential direction at least partially embossing or perforations, which are designed as predetermined breaking points, and the bonding or welding of the inner surface of the lid portion with the surface of the sealing film is using the liner only in the range of made the embossments or perforations surrounded area.
- a sealing film a plate which is composed of at least two layers, wherein the inner surface of the lid portion facing layer of substantially PE, PET or aluminum and the neck facing layer of PE, PET or sealing wax or a combination of the aforementioned substances can exist.
- the formation can be made such that only the inner surface of the lid portion facing layer of the sealing film within the clear width of the neck is at least partially coined or perforated in the circumferential direction.
- the embossing or the perforation is preferably circular in circumference.
- the lid portion has a reverse anvil-like inner tabular projection having the inner surface, such that this inner surface od when screwing the screw cap on the neck of the container. The like. Reliable to rest on the surface of the sealing foil can be brought.
- the vessel used, the container used, the bottle used or the like can be made of glass, plastic or the like.
- the sealing foil which consists in particular of aluminum and / or of plastic, has a peripheral region projecting radially beyond the edge of the neck.
- This peripheral region forms an additional guide for the or the separating blade, so to speak as a barrier to the lid of the screw cap, in particular, as soon as in the presence of a Anyaklippe the same lifts off when unscrewing the screw cap and such a peripheral region, which had previously nestled, progressively releases, such that the or the separating blade is guided under this peripheral region at the same fitting to the sealing surface or be.
- the screw cap according to the invention is preferably made of plastic.
- Fig. 1 the shoulder region 2 of a bottle 1 with a neck 3 is shown, which has an external thread 4 and a central axis 5. Furthermore, a screw cap 7 having an internal thread 6 is shown which, like the bottle 1, can be made of plastic, for example, such as PE or PET. This screw cap 7 is provided with a cover portion 8 and a female portion 6 having sleeve portion 9 with a screw-10, for screwing on and unscrewing of the external thread 4 of an edge 11 having neck 3 of the bottle first
- This neck 3 is connected by means of a to an annular sealing surface 12 ( Fig. 10 ) of the edge 11 of the neck 3 sealed, a radially projecting peripheral region 13 possessing sealing film 14 hermetically sealed.
- This sealing film 14 is detachable and / or destructible for releasing the respective contents of the bottle.
- This end position according to Fig. 5 is such that when unscrewing the screw cap 7 by, between the protruding periphery 13 of the sealing film 14 and the edge 11 of the neck 3 of the bottle 1 first obliquely directed to the sealing film 14 and the central axis 5 and subsequently continuously by their spring back more and more radially inwardly to the central axis 5 circumferentially penetrating, cutting edge 16 of the severing blade 15, the sealing film 14 from the edge 11 of Bottle 1 towards the central axis 5 toward progressively separable and in the Aufschraubkappe 7 between Abtrennmesser 15 and cover portion 8 is preserved.
- the beginning of the attack of the cutting edges 16 on the sealing surface between the edge 11 or the same Sigel Chemistry 12 and the sealing film 14 is in Fig. 7 shown.
- the inside width W of the individual blade 15 corresponds to the clear width of the edge 11 of the neck 3.
- three cut-off blades 15 are provided here.
- only one separating knife 15 is present, it can be formed circumferentially along the inner circumference 9 'of the sleeve section 9, ie as a ring cutter (not shown), the elasticity of the material of the screw cap 7 and thus of the ring cutter for the required deflectability thereof in the direction of the central axis 5 worries.
- the Anticianlippe 23 remains due to their length and their effort when unscrewing the screw cap 7 in Oberzufedern substantially to their original position, first in decreasing contact with the top of the sealing film 14 and the reinforcing plate 22 before it completely stands out from the sealing film 14 and the reinforcing plate 22 during further unscrewing the screw cap 7.
- a reinforcing plate 22 can also be used prior to sealing the top of the sealing film 14 have been connected flat, z. B. also by welding means of a thermoplastic or by gluing, thus even before the sealing film 14 is sealed onto the sealing surface 12 of the edge 11 of the neck 3 of the bottle 1.
- the cutting edges 16 push under the action of the existing restoring forces of the three Abtrennmesser 15 below the peripheral portion 13 of the sealing film 14 and lift it together with the edge of the overlying reinforcing plate 22, as the Fig. 7 clarified.
- each a groove 25 to adapt to the rounding of the edge 11 of the neck 3 shown follows, and on the other hand, that the are adjacent to the cutting edges 16 on the side facing away from the neck 3 subsequent areas of the cutting blade 15 are rounded.
- the separating blades thus have, so to speak, in their areas adjacent to the cutting edges 16, a bend which favors the penetration of the cutting edges 16.
- the An réellelippe lifts 23, the first their pressure in the entire dotted indicated area 26 (FIG. Fig. 6 ), partially from the surface of the edge of the sealing foil 14 or, in the case shown here, from the inside to the outside of the edge of the reinforcing plate 22 from.
- the separating blades 15 in reaching the position according to Fig. 9 the sealing surface 12 cut through and the sealing film 14 with the reinforcing plate 22 completely detached. Since the Abtrennmesser 15 strive to go back to their original positions, which they held before screwing the screw cap 7 on the neck 3, finally results in the Fig. 10 illustrated position of the separated sealing film 14 plus reinforcing plate 22 within the lifted screw cap 7 according to Fig. 10 ,
- an intermediate layer 33 made of a thermoplastic, an adhesive and / or a sealing wax is applied between the lid section 8' or its inner surface 21 and sealing foil 14 '.
- a sealing film 14 ' is expediently used, which has at least partially embossments or perforations 28 within the clear width W of the neck 3 in the circumferential direction, which are designed as predetermined breaking points, wherein the bonding or welding of the inner surface 21 of the cover portions 8' with the surface of the Sealing film 14 'by means of the intermediate layer 25 only in the area of the embossments or perforations 28 circumscribed surface 32 is made.
- embossments or perforations reduce the force required for tearing open the sealing film 14 'when unscrewing the screw cap 7' considerably.
- a sealing film 14 ' is in this embodiment a small plate 31 ( Fig. 15 ), which is composed of two layers 26 and 27, wherein the inner surface 21 of the lid portion 8 'facing layer 26 made of PE, PET or aluminum and the neck 3 facing layer 27 of PE, PET or sealing wax or a combination of these Substances can exist.
- the perforation (28) is circumferentially circular.
- a screw cap 7 ' for carrying out the described method according to this second embodiment, again in particular made of plastic, with a cover portion 8' and a female thread 6 having sleeve portion 9 "with a screw-10, for screwing on and unscrewing from an external thread 4 a or the like made of plastic, glass or the like, which has been hermetically sealed by means of a sealed to an annular sealing surface 12 of the edge 11 of the neck 1 sealing film 14 ', releasable to release a bottle contents and / or destructible, according to the invention, the lid portion 8 'has a reverse anvil-like, the inner surface 21 having, inner, tabular, projection 32, such that when screwing the screw cap 7' on the neck 3 of the Container 1 or the like.
- the thread pitch and the thread pairing 4, 6 dimensioned such that the stroke of the screw cap 7, 70 relative to the neck 3 is about 9mm per revolution of the screw cap 7, 70 by 360 degrees.
- the training can be made so that the internal thread 6 is three-speed.
- Fig. 16 shows a further embodiment of the invention with a screw cap 70th
- the imaginary circumference of the circumference of the periphery (11) of the neck (3) is formed, such that the Abtrennmesser 15 and the Abtrennmesser solve the sealing surface 12 in any case completely. But this is by no means always necessary, but it may also be sufficient, if necessary, not completely to solve the sealing surface 12, d. H.
- the severing blade 15 or the severing blade is arranged on the inner circumference 9 'of the sleeve section 9 above the internal thread 6 towards the cover section 8 and the thread of this internal thread 6 has interruptions 71 which are in relation to their width u in the circumferential direction of the inner circumference 9 'of the width of the severing blade 15 and the Abtrennmesser are substantially equal or slightly wider, such that when removing the screw cap 70 upwards from the respective mold (not shown) the Abtrennmesser 15 and the Abtrennmesser down can be pushed into these interruptions 71 and find themselves in the same place at short notice, until they emerge from the mold and become free.
- This embodiment with the interruptions 71 allows a considerable saving in height of the screw cap 70 and thus plastic material, since the Abtrennmesser 15 can be arranged closer to the internal thread 6, and at the same time avoids problems with the removal of the screw cap 70 from their form, in particular has been injection-molded in the preferred use of plastic.
- the interruptions 71 the height of a screw cap must be necessarily greater, because when removing the same from the mold, the separating blade 15 once inevitably fold down and need to find space without the interruptions 71 completely above the threads.
- the severing blade 15 and the severing blades each have (s) free end (s) having the cutting edge (s), the seal (s) between the sealing film 14 and the sealing surface 12 upon engagement with the sealing surface 12
- Edge 11 a curvature or buckling on the edge 11 to have or have (particularly clearly from the Fig. 3 and 6 refer to). This favors the penetration of the cutting edge (s) 19 between the sealing film 14 and the edge 11, not only when the sealing foil 14, which is expediently made of aluminum and / or plastic, has a circumferential region 13 projecting radially beyond the edge 11 of the neck 3.
- the screw cap 70 can also on the inside of the lid portion 8 between at least one concentric circumferential, here relatively short, ie, a small height having Anyaklippe 23 and the inner wall 9 'of the sleeve portion 9 a circumferential counter-pressure lip 72 (FIG. Fig. 16 ), which presses when screwing the screw cap on the neck 3 against the sealing foil 14 and is suitable for unscrewing the screw cap, supported by their restoring force the edge of the sealing foil 14 against the pressure of the ends of the or the separating blade 15, such that these ends better under the peripheral portion 13 of the sealing film 14 slide and can penetrate into the sealing surface 12.
- this peripheral region 13 does not necessarily have to survive beyond the edge 11 of the neck 3. He also does not necessarily have a non-glued or not sealed peripheral edge to a proper grip from the cutting edge (s) 19 of the or the Abtrennmesser (s) 15 to ensure.
- the relevant respective embodiment according to the invention is dependent on the parameters given in each case, of which only the material of the screw cap itself, the material of the sealing film 14, the material of the binder used and the elasticity of the or the separating blade (s) called should be.
- the screw cap 70 for example, no reinforcing plate 22 is used for a sealing film 14 which may be necessary for this, as described in the preceding embodiments, for which reason the counterpressure lip 72 is advantageous here.
- the pressure lip 23, whether in the embodiments according to the FIGS. 1 to 10 or in the embodiment according to Fig. 16 , Not only the pressing of a peripheral portion 13 of the sealing film 14 is used, if such a peripheral region is present, but also the repeated sealing of the neck 3 z.
- the sealing film 14 has been lifted and the bottle after each unscrewing the screw cap 7, 7 'or 70 and the removal of a subset is screwed back to close the bottle again tight.

Für übliche Kunststoffflaschen aus beispielsweise Polyäthylen (PE) oder Polyäthylenterephthalat (PET) werden im allgemeinen Aluminiumfolien verwendet, die an ihrer Siegelseite eine Beschichtung mit z. B. HDPE (High Density Polyäthylen) od. dergl. aufweisen. Nach dem Auflegen einer solchen Siegelfolie auf den Flaschenrand erfolgt eine Verschweißung der Beschichtung der Siegelfolie mit dem Rand der Flasche. Die Siegelfolie haftet anschließend fest und undurchdringlich an dem Rand an. Statt einer Verschweißung kann auch eine Verklebung stattfinden.If you want the possibly already sterile content z. B. a bottle for a long time from external influences, such as the penetration of microbes or other contaminants protect, then it is still state of the art, aufzusiegeln on the mouth edge of this bottle an impermeable to these substances sealing film such that the actual sealing surface of these substances not can be penetrated. For conventional plastic bottles such as polyethylene (PE) or polyethylene terephthalate (PET) aluminum foils are generally used on their sealing side a coating with z. B. HDPE (High Density Polyethylene) od. Like. Have. After placing such a sealing foil on the edge of the bottle, the coating of the sealing foil is welded to the edge of the bottle. The sealing film then adheres firmly and imperviously to the edge. Instead of a weld can also take place a bond.
Sodann erfolgt bei diesem Stand der Technik das Aufschrauben einer Schraubkappe, um zunächst die Siegelfolie zu schützen, die dann vom Verbraucher nach dem Abschrauben der Schraubkappe und, falls vorhanden, Abreißen eines Originalitätsverschlussrings an derselben, von Hand zu lösen ist bzw. abgezogen werden kann, um an den Inhalt zu gelangen. Vor allem bei nur teilweisem Verbrauch des Flascheninhalts lässt sich die Flasche mit dem verbliebenen Inhaltsrest anschließend durch erneutes Aufschrauben der Schraubkappe wieder verschließen.Then, in this prior art, the screwing of a screw cap to protect first the sealing film, which is then by the consumer after unscrewing the screw cap and, if present, tearing off a tamper-evident ring on the same to solve by hand or can be deducted, to get to the content. Especially with only partial consumption of the contents of the bottle, the bottle with the remaining remainder of the contents can then be closed again by re-screwing the screw cap.
Es wird nun vom Verbraucher als unkomfortabel empfunden, bei jeder frischen, z. B. Milch oder Fruchtsaft enthaltenden, Flasche nicht nur die Schraubkappe abschrauben zu müssen, sondern auch noch gezwungen zu sein, einen über den Rand des Halses der Flasche vorstehenden Umfang der Siegelfolie erfassen und dieselbe dann abziehen zu müssen, was ein gewisses Geschick erfordert.It is now perceived by the consumer as uncomfortable, with each fresh, z. B. containing milk or fruit juice, bottle not only need to unscrew the screw cap, but also to be forced to detect an over the edge of the neck of the bottle protruding circumference of the sealing film and then deduct the same, which requires a certain skill.
Aus der Europäischen Patentanmeldung
Die der Erfindung zugrunde liegende Aufgabe wird nun darin gesehen, ein Verfahren und eine Schraubkappe zur Ausführung des Verfahrens der eingangs genannten Art zu schaffen, durch die ein besonderes Ergreifen und Abziehen der Siegelfolie von Hand nach dem Abschrauben der Schraubkappe unnötig wird.The object underlying the invention is now seen to provide a method and a screw cap for carrying out the method of the type mentioned , by a special seizing and peeling off the sealing film by hand after unscrewing the screw cap is unnecessary.
Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art gemäß einer ersten Ausführungsform der Erfindung dadurch gelöst, dass beim Abschrauben der Schraubkappe von dem Hals die Siegelfolie vom äußeren Umfang des Randes des Halses her radial nach innen zur Mittelachse hin fortschreitend durch die Schraubkappe zumindest teilweise gelöst und anschließend vom Rand abgehoben wird.This object is achieved in a method of the type mentioned above according to a first embodiment of the invention in that when unscrewing the screw cap from the neck, the sealing film from the outer periphery of the edge of the neck ago radially inwardly towards the central axis progressively solved by the screw cap at least partially and then lifted off the edge.
Dabei kann gegebenenfalls vorgesehen sein, die abgelöste Siegelfolie anschließend in der Schraubkappe zu behalten.It may optionally be provided to then keep the detached sealing film in the screw cap.
Der Vorgang des Abschraubens der Schraubkappe umfasst somit erfindungsgemäß das Lösen der Siegelfolie vom Rand des Gefäßes bzw. der Flasche und gegebenenfalls auch die anschließende Aufbewahrung der Siegelfolie in der Schraubkappe, die beliebig oft, wie gewohnt, wieder auf den Hals aufgeschraubt und abgeschraubt werden kann, bis der Behälterinhalt durch jeweilige Entnahme erschöpft ist. Ein gesondertes Lösen der Siegelfolie von Hand ist damit unnötig geworden.The process of unscrewing the screw cap thus includes according to the invention, the release of the sealing film from the edge of the vessel or the bottle and possibly also the subsequent storage of the sealing film in the screw cap, which can be screwed on and unscrewed as often as usual, again until the container contents are exhausted by respective removal. Separate release of the sealing film by hand has become unnecessary.
Vorteilhaft kann vor dem ersten Aufschrauben der Schraubkappe auf das Außengewinde des Halses ein einseitig mit einem Haftmittel beschichtetes Versteifungsplättchen in die Schraubkappe eingesetzt und beim darauf folgenden Aufschrauben mit dem Haftmittel gegen die am Rand des Halses angesiegelte Siegelfolie gepresst werden, wobei nach der Beendigung des Aufschraubens ein flächiges Verbinden des Verstärkungsplättchens mit der Siegelfolie erfolgt. Auf diese Weise findet eine zweckmäßige Verstärkung der im allgemeinen recht dünnen und biegsamen Siegelfolie statt, die dazu dient, den Angriff seitens des Schraubverschlusses an der Siegelfolie zu erleichtern.Advantageously, before the first screwing the screw cap on the external thread of the neck coated on one side with an adhesive Reinforced plates are inserted into the screw cap and pressed in the subsequent screwing with the adhesive against the sealed at the edge of the neck seal film, wherein after completion of screwing a surface bonding of the reinforcing plate with the sealing film. In this way, there is a convenient reinforcement of the generally quite thin and flexible sealing film, which serves to facilitate the attack by the screw on the sealing film.
Es wird bevorzugt, zum flächigen Verbinden des Versteifungsplättchens mit der Siegelfolie unter Verwendung eines Thermoplasts als Haftmittel ein Induktionsschweißen zu benutzen.It is preferable to use induction welding for bonding the stiffening plate to the sealing film by using a thermoplastic adhesive as the adhesive.
Es ist auch möglich, eine Verstärkung der Siegelfolie dadurch vorzunehmen, dass von vorneherein, also beim Versiegeln des Halses des Gefäßes bzw. der Flasche, eine durch ein flächig verbundenes Versteifungsplättchen bereits verstärkte oder eine in sich bereits ausreichend versteifte bzw. biegeresistente Siegelfolie verwendet wird.It is also possible to reinforce the sealing film in that from the outset, that is to say when sealing the neck of the vessel or the bottle, a reinforcing plate already reinforced or even sufficiently stiffened or resistant to bending is used.
Ferner kann als Haftmittel auf der der Siegelfolie zugewandten Fläche des Versteifungsplättchens ein Klebemittel, eine Kaschierung oder auch ein Siegellack aus beispielsweise PE, PET, Polyester oder Polystyrol oder aus einer Kombination dieser Stoffe verwendet werden.Furthermore, an adhesive, a lamination or else a sealing lacquer of, for example, PE, PET, polyester or polystyrene or of a combination of these substances can be used as the adhesive on the surface of the stiffening plate facing the sealing film.
Eine Schraubkappe zur Ausführung des Verfahrens nach der Erfindung besitzt einen Deckelabschnitt und einen ein Innengewinde aufweisenden Hülsenabschnitt mit einer Aufschrauböffnung, zum Aufschrauben auf ein und Abschrauben von einem Außengewinde eines einen Rand aufweisenden Halses einer Flasche od. dergl., der mittels einer an eine kreisförmige Siegelfläche des Randes des Halses angesiegelten, einen radial überstehenden Umfangsbereich besitzenden, Siegelfolie hermetisch verschlossen wurde, die zum Freigeben eines Flascheninhalts lösbar und/oder zerstörbar ist.A screw cap for carrying out the method according to the invention has a lid portion and a An internally threaded sleeve portion with a screw-on, for screwing on and unscrewing from an external thread of an edge having a neck of a bottle od. Like. Hermetically sealed by means of a sealed to a circular sealing surface of the edge of the neck, possessing a radially projecting peripheral portion, sealing foil which is releasable and / or destructible to release a bottle contents.
Erfindungsgemäß ist nun diese Schraubkappe und damit eine erste vorrichtungsmäßige Lösung der genannten Aufgabe gekennzeichnet durch mindestens ein zwischen dem Innengewinde und dem Deckelabschnitt am Hülsenabschnitt längs dessen Innenumfangs angeordnetes, in Ausgangsstellung vor dem Aufschrauben schräg zur Aufschrauböffnung hin und nach innen zur Mittelachse des Halses bzw. der Schraubkappe weisendes Abtrennmesser, dessen Abstand von der Mittelachse vor dem Aufschrauben kleiner ist als der Außendurchmesser des Randes des Halses, und das beim Aufschrauben der Schraubkappe auf den Hals der Flasche elastisch ausgelenkt wird, wobei das Abtrennmesser mit seiner Schneidkante infolge des Drucks des Randes des Halses und des Umfangsbereichs der Siegelfolie federnd nach oben klappt und oberhalb des Außengewindes und unterhalb des radial überstehenden Umfangsbereichs der Siegelfolie, elastisch verformt und zur Mittelachse hin federnd vorgespannt, am Außenumfang des Halses zur Anlage kommt, sobald das Aufschrauben beendet ist,
und dadurch, dass bei einem Abschrauben der Schraubkappe die Schneidkante des Abtrennmessers zunächst schräg zur Siegelfolie und zur Mittelachse hin gerichtet ist und nachfolgend kontinuierlich durch ihr Zurückfedern mehr und mehr radial nach innen zur Mittelachse hin zwischen dem überstehenden Umfangsbereich der Siegelfolie und dem Rand des Halses der Flasche eindringt, wobei die Siegelfolie vom Rand der Flasche zur Mittelachse hin fortschreitend abtrennbar und in der Aufschraubkappe zwischen Abtrennmesser und Deckelabschnitt bewahrbar ist.According to the invention, this screw cap and thus a first device solution of the above object is characterized by at least one between the internal thread and the lid portion on the sleeve portion along the inner circumference arranged in the starting position before screwing obliquely to the screw-in and out towards the center axis of the neck or the Screw cap-facing cutting blade, whose distance from the central axis before screwing is smaller than the outer diameter of the edge of the neck, and which is elastically deflected when screwing the screw cap on the neck of the bottle, the cutting blade with its cutting edge due to the pressure of the edge of the neck and the peripheral portion of the sealing film resiliently folds upwards and above the external thread and below the radially projecting peripheral portion of the sealing film, elastically deformed and resiliently biased towards the center axis, on the outer circumference of the neck for investment e comes as soon as the screwing is finished,
and in that, when unscrewing the screw cap, the cutting edge of the severing knife is initially directed obliquely to the sealing foil and to the central axis, and subsequently continuously penetrates more and more radially inwardly toward the central axis between the projecting peripheral region of the sealing film and the edge of the neck of the bottle, the sealing film from the edge of the bottle towards the center axis progressively separable and preserved in the Aufschraubkappe between separating blade and lid portion is.
Wie ersichtlich, löst die erfindungsgemäße Schraubkappe bei ihrem Abschrauben die am freien Rand des Halses der Flasche od. dergl. angesiegelte Siegelfolie dadurch, dass das Abtrennmesser von außen her zwischen dem Rand des Halses der Flasche und der Siegelfolie, erforderlichenfalls bis über den Innendurchmesser des Halses hinaus, in Richtung auf die Mittelachse desselben fortschreitend eindringt und die Siegelfolie nach dem Lösen mitnimmt, da die abgetrennte Siegelfolie zwischen dem Abtrennmesser und dem Deckelabschnitt festgehalten wird.As can be seen, the screw cap according to the invention triggers when unscrewing the od at the free edge of the neck of the bottle or the like. Sealed seal film in that the Abtrennmesser from the outside between the edge of the neck of the bottle and the sealing film, if necessary, to about the inner diameter of the neck out, gradually penetrates toward the center axis of the same and entrains the sealing film after loosening, since the separated sealing film is held between the separating blade and the lid portion.
Bei einer bevorzugten Ausführungsform ist eine Mehrzahl von einzelnen, längs des Innenumfangs des Hülsenabschnitts in Umfangs- bzw. Drehrichtung verteilten und mit dem Hülsenabschnitt fest verbundenen Abtrennmessern vorgesehen, die bei flächiger Radialstellung in gemeinsamer Ebene im Bereich der Mittelachse eine lichte Weite lassen, die einen geringeren Durchmesser aufweist als die kreisringförmige Siegelfläche, bzw. als ihn der Außendurchmesser des Randes des Halses der Flasche od. dergl. besitzt. In Abhängigkeit von den Eigenschaften des verwendeten Haftmittels und damit der Intensität der Verbindung kann es gegebenenfalls schon ausreichen, wenn das Abtrennmesser die Siegelfolie nur teilweise durch sein spiraliges Schneiden abtrennt und deren restliches Abheben bzw. Abreißen einfach durch das weitere Anheben des Umfangsbereichs der Siegelfolie beim weiteren Abschrauben und damit durch die an der Siegelfläche der Siegelfolie ausgeübte Zugspannung bewirkt.In a preferred embodiment, a plurality of individual, along the inner circumference of the sleeve portion distributed in the circumferential or rotational direction and fixedly connected to the sleeve portion separating blades are provided, which leave a clear width in planar radial position in the common plane in the region of the central axis, which has a lesser width Has diameter than the annular sealing surface, or as it has the outer diameter of the edge of the neck of the bottle od. Like. Has. Depending on the properties of the adhesive used and thus the intensity of the compound can it may already be sufficient if the severing knife separates the sealing film only partially by its spiral cutting and causes its remaining lifting or tearing off simply by the further lifting of the peripheral region of the sealing film during further unscrewing and thus by the tension exerted on the sealing surface of the sealing film.
Dabei weist zweckmäßig jedes einzelne Abtrennmesser eine teilweise in die Abschraubrichtung weisende Schneidkante auf, die jeweils das spiralig nach innen laufende Einschneiden in die Siegelfläche zwischen Siegelfolie und Rand des Halses bewirkt.In this case, each individual severing knife expediently has a cutting edge partially pointing in the unscrewing direction, which in each case causes the spiraling inward cutting into the sealing surface between the sealing film and the edge of the neck.
Jede Schneidkante kann vorteilhaft konkav gebogen sein und einen radial vorspringenden, in Abschraubdrehrichtung nachlaufenden spitzen Schneidvorsprung aufweisen, der das Eindringen in die Siegelfläche begünstigt.Each cutting edge may advantageously be curved concavely and have a radially projecting, in Abschraubdrehrichtung trailing tip cutting projection, which favors the penetration into the sealing surface.
Es ist besonders zweckmäßig, dass auf der Innenseite des Deckelabschnitts der Schraubkappe mindestens eine, kreisförmig um die Mittelachse herum und dem Umfang der Siegelfolie mit gegebenenfalls ihrem Verstärkungsplättchen gegenüberliegend angeordnete, Andrucklippe angeformt ist, die beim Festschrauben der Schraubkappe den Umfangsbereich von Siegelfolie und gegebenenfalls Verstärkungsplättchen an den Rand des Halses andrückt und an denselben anschmiegt.It is particularly expedient that on the inside of the lid portion of the screw cap at least one, around the central axis and the circumference of the sealing film with possibly its reinforcing plate opposite arranged, Andrucklippe is formed, which when tightening the screw on the peripheral portion of sealing film and optionally reinforcing plate on press the edge of the neck and cling to it.
Diese Verformung des Umfangs der Siegelfolie einerseits und des Verstärkungsplättchens, so vorhanden, andererseits begünstigt ebenfalls das Eindringen des oder der Abtrennmesser in den Spalt zwischen Siegelfolie und Rand, da der Umfang der Siegelfolie und gegebenenfalls des Verstärkungsplättchens eine schräg zur Siegelfolie und zur Mittelachse hin weisende Führung für das bzw. die Abtrennmesser bildet, derart, dass das bzw. die Abtrennmesser zwischen Siegelfolie und Rand gleitend und beim fortschreitenden Abschrauben der Schraubkappe sich mehr und mehr in eine waagerechte Schneidebene begebend und dabei zwischen Siegelfolie und Rand bis, falls erforderlich, in den freien Raum in der lichten Weite des Halses eindringend die Siegelfolie vollständig ablösen kann bzw. können. Wenn sich das bzw. die Abtrennmesser beim weiteren Abschrauben dann vom Rand des Halses der Flasche od. dergl. abheben, kann es bzw. können sie wieder weitgehend in seine bzw. ihre Ausgangslage zurückkehren, die es bzw. sie vor dem Aufschrauben der Kappe hatte bzw. hatten, nämlich schräg zur Aufschrauböffnung und zur Mitte hin.This deformation of the circumference of the sealing film on the one hand and the reinforcing plate, if present, on the other hand also favors the penetration of the or the severing knife in the gap between the sealing film and the edge, since the circumference of the sealing film and optionally the reinforcing plate forms an obliquely to the sealing film and to the central axis facing guide for the or the separating blade, such that the or the separating blade between the sealing film and the edge sliding and progressively unscrewing the screw more and more issuing in a horizontal cutting plane and thereby between the sealing film and edge to, if necessary, in the free space in the clearance of the neck penetrating the sealing film can completely replace or can. If the separation knife or the other od then further from the edge of the neck of the bottle. Like. Stand out, it or they can largely return to its original position, she or she had before screwing the cap or had, namely obliquely to Aufschrauböffnung and the center out.
Bei Vorhandensein nur eines Abtrennmessers kann dieses längs des Innenumfangs des Hülsenabschnitts umlaufend, also als Ringmesser, ausgebildet sein. Die Elastizität des Materials der Schraubkappe sorgt für die erforderliche Auslenkbarkeit dieses Ringmessers in Richtung der Mittelachse.If only one separating knife is present, it can be formed circumferentially along the inner circumference of the sleeve section, ie as a ring knife. The elasticity of the material of the screw cap ensures the required deflectability of this ring diameter in the direction of the central axis.
Es ist jedoch zu betonen, daß die beschriebene Ausrichtung des bzw. der Abtrennmesser(s) in seiner bzw. ihrer Ausgangsstellung, in der es bzw. sie vor einem Aufschrauben der Schraubkappe auf den Hals des Behälters bzw. der Flasche schräg zur Aufschrauböffnung und nach innen zur Mittelachse hin weist bzw. weisen, nicht zwangsläufig so sein muß. Vielmehr kann die Messerausrichtung durch die Ausgestaltung der Messerform einerseits und den jeweiligen Anschluß am Hülsenabschnitt längs dessen Innenumfangs andererseits auch so getroffen werden, daß das bzw. die Abtrennmesser schräg zum Deckelabschnitt und nach innen zur Mittelachse hin weist bzw. weisen. In diesem Fall besitzt das Abtrennmesser bzw. besitzen die Abtrennmesser bereits im wesentlichen diejenige Ausrichtung, die es bzw. sie für den Vorgang des Abtrennens der Siegelfolie vom Hals benötigt bzw. benötigen.However, it should be emphasized that the described orientation of the or the separating knife (s) in his or her original position in which it or before screwing the screw cap on the neck of the container or the bottle obliquely to the screw-on and after pointing towards the central axis or pointing, does not necessarily have to be so. Rather, the Knife alignment by the configuration of the knife shape on the one hand and the respective terminal on the sleeve portion along the inner circumference on the other hand also be taken so that the or the Abtrennmesser obliquely to the lid portion and inwardly towards the central axis has or point. In this case, the severing knife or the cut-off knife already essentially has the orientation that it or they need or need for the process of separating the sealing film from the neck.
Die genannte Aufgabe wird ferner bei einem Verfahren der eingangs genannten Art gemäß einer zweiten Ausführungsform der Erfindung auch dadurch gelöst, dass vor dem Aufschrauben der Schraubkappe auf den Hals des Behälters od. dergl. eine Zwischenlage aus einemThe above object is further achieved in a method of the type mentioned above according to a second embodiment of the invention also in that before screwing the screw cap on the neck of the container od. Like. An intermediate layer of a
Klebstoff und/oder einem Siegellack zwischen Deckelabschnitt und Hals eingebracht wird, daß beim Aufschrauben der Schraubkappe auf den Hals des Behälters die Zwischenlage von der Innenfläche des Deckelabschnitts auf die Siegelfolie gepresst wird, und daß anschließend die Innenfläche mit der Oberfläche der Siegelfolie verklebt oder verschweißt wird, derart, daß die Siegelfolie an der Innenfläche fest anhaftet und daß beim Abschrauben der Schraubkappe vom Hals des Behälters bzw. der Flasche die Siegelfolie von der Schraubkappe zumindest teilweise mitgerissen wird.Adhesive and / or a sealing wax between the lid portion and neck is introduced, that when screwing the screw cap on the neck of the container, the intermediate layer is pressed by the inner surface of the lid portion on the sealing film, and that subsequently the inner surface is glued or welded to the surface of the sealing film such that the sealing film firmly adheres to the inner surface and that when unscrewing the screw cap from the neck of the container or the bottle, the sealing film is at least partially entrained by the screw cap.
Dieses Mitreißen erfolgt in Drehrichtung der Schraubkappe, der mitgerissene Abschnitt der Siegelfolie bleibt an der Innenfläche des Deckelabschnitts haften.This entrainment takes place in the direction of rotation of the screw cap, the entrained portion of the sealing film adheres to the inner surface of the lid portion.
Der jeweilige Behälter ist somit nach dem Abschrauben der Schraubkappe ganz oder zumindest teilweise geöffnet, so daß der Inhalt entnommen werden kann.The respective container is thus completely or at least partially opened after unscrewing the screw cap, so that the contents can be removed.
Vorteilhaft weist dabei die Siegelfolie innerhalb der lichten Weite des Halses in Umfangsrichtung zumindest abschnittsweise Prägungen oder Perforationen aufweist, die als Sollbruchstellen ausgeführt sind, und die Verklebung oder Verschweißung der Innenfläche des Deckelabschnitts mit der Oberfläche der Siegelfolie wird mit Hilfe der Zwischenlage nur im Bereich der von den Prägungen oder Perforationen umgebenen Fläche vorgenommen.Advantageously, in this case, the sealing film within the clear width of the neck in the circumferential direction at least partially embossing or perforations, which are designed as predetermined breaking points, and the bonding or welding of the inner surface of the lid portion with the surface of the sealing film is using the liner only in the range of made the embossments or perforations surrounded area.
Dies schafft die Möglichkeit, einen zentralen Bereich der Siegelfolie beim Abschrauben der Schraubkappe kontrolliert durchzureißen.This creates the opportunity to inspect a central region of the sealing film controlled when unscrewing the screw cap.
Zweckmäßig wird dabei als Siegelfolie ein Plättchen verwendet, das aus mindestens zwei Schichten aufgebaut ist, wobei die der Innenfläche des Deckelabschnitts zugewandte Schicht aus im wesentlichen PE, PET oder Aluminium und die dem Hals zugewandte Schicht aus PE, PET oder Siegellack oder aus einer Kombination der vorgenannten Stoffe bestehen kann.Appropriately used as a sealing film, a plate which is composed of at least two layers, wherein the inner surface of the lid portion facing layer of substantially PE, PET or aluminum and the neck facing layer of PE, PET or sealing wax or a combination of the aforementioned substances can exist.
Dabei kann die Ausbildung derart getroffen werden, daß nur die der Innenfläche des Deckelabschnitts zugewandte Schicht der Siegelfolie innerhalb der lichten Weite des Halses in Umfangsrichtung zumindest abschnittsweise geprägt oder perforiert wird.In this case, the formation can be made such that only the inner surface of the lid portion facing layer of the sealing film within the clear width of the neck is at least partially coined or perforated in the circumferential direction.
Dabei ist die Prägung oder die Perforation bevorzugt umlaufend kreisförmig.The embossing or the perforation is preferably circular in circumference.
Eine bevorzugte Schraubkappe zur Ausführung des Verfahrens nach dieser zweiten Ausführungsform der Erfindung und damit eine zweite vorrichtungsmäßige Lösung der genannten Aufgabe, insbesondere aus Kunststoff, mit einem Deckelabschnitt und einem ein Innengewinde aufweisenden Hülsenabschnitt mit einer Aufschrauböffnung zum Aufschrauben auf ein und Abschrauben von einem Außengewinde eines einen Rand aufweisenden Halses einer Flasche od. dergl., der mittels einer an eine kreisringförmige Siegelfläche des Randes des Halses angesiegelten Siegelfolie hermetisch verschlossen ist, ist erfindungsgemäß dadurch gekennzeichnet, daß der Deckelabschnitt einen umgekehrt amboßartigen, die Innenfläche aufweisenden, inneren, tafelartigen, Vorsprung besitzt, derart daß diese Innenfläche beim Aufschrauben der Schraubkappe auf den Hals des Behälters od. dergl. zuverlässig zur Anlage an der Oberfläche der Siegelfolie bringbar ist.A preferred screw cap for carrying out the method according to this second embodiment of the invention and thus a second device solution of the above object, in particular of plastic, with a cover portion and a sleeve portion having an internal thread with a screw-on for screwing on and unscrewing an external thread of a According to the invention , the lid portion has a reverse anvil-like inner tabular projection having the inner surface, such that this inner surface od when screwing the screw cap on the neck of the container. The like. Reliable to rest on the surface of the sealing foil can be brought.
Das jeweils verwendete Gefäß, der verwendete Behälter, die verwendete Flasche od. dergl. können aus Glas, aus Kunststoff od. dergl. bestehen.The vessel used, the container used, the bottle used or the like can be made of glass, plastic or the like.
Vorzugsweise weist die insbesondere aus Aluminium und/oder aus Kunststoff bestehende Siegelfolie einen über den Rand des Halses radial überstehenden Umfangsbereich auf. Dieser Umfangsbereich bildet eine zusätzliche Führung für das bzw. die Abtrennmesser, sozusagen als Barriere zum Deckel der Schraubkappe hin, insbesondere, sobald bei Vorhandensein einer Andrucklippe sich dieselbe beim Abschrauben der Schraubkappe abhebt und einen solchen Umfangsbereich, den sie vorher angeschmiegt hatte, fortschreitend freigibt, derart, daß das bzw. die Abtrennmesser unter diesem Umfangsbereich an demselben anliegend zur Siegelfläche geführt wird bzw. werden.Preferably, the sealing foil, which consists in particular of aluminum and / or of plastic, has a peripheral region projecting radially beyond the edge of the neck. This peripheral region forms an additional guide for the or the separating blade, so to speak as a barrier to the lid of the screw cap, in particular, as soon as in the presence of a Andrucklippe the same lifts off when unscrewing the screw cap and such a peripheral region, which had previously nestled, progressively releases, such that the or the separating blade is guided under this peripheral region at the same fitting to the sealing surface or be.
Die erfindungsgemäße Schraubkappe besteht vorzugsweise aus Kunststoff.The screw cap according to the invention is preferably made of plastic.

Zeigt es sich infolge von vorneherein zu großer Flexibilität im Umfangsbereich 13 der Siegelfolie 14 als a priori erforderlich, die letztere zu verstärken, um ein einwandfreies Entlanggleiten der Einzelmesser 18 unterhalb der Siegelfolie 14 zu gewährleisten, dann kann auch schon vor dem Aufsiegeln ein Verstärkungsplättchen 22 mit der Oberseite der Siegelfolie 14 flächig verbunden worden sein, z. B. ebenfalls durch ein Verschweißen mittel eines Thermoplasts oder auch durch ein Verkleben, somit bereits bevor die Siegelfolie 14 auf die Siegelfläche 12 des Randes 11 des Halses 3 der Flasche 1 aufgesiegelt wird.If, as a result, there is a great deal of flexibility in the

Auch hierbei handelt es sich um ein Verfahren zum zumindest teilweisen Ablösen bzw. Abtrennen einer, auf einen eine kreisförmige Siegelfläche 12 besitzenden Rand 11 eines ein Außengewinde 4 und eine Mittelachse 5 aufweisenden Halses 3 eines Behälters, insbesondere einer Flasche 1 od. dergl. aus Kunststoff, Glas od. dergl. mit einer aufgesiegelten, insbesondere aus Aluminium und/oder aus Kunststoff bestehenden Siegelfolie 14', wobei auf das Außengewinde (4) des derart versiegelten Halses (3) eine ein zum Außengewinde (4) passendes Innengewinde (6) aufweisende Schraubkappe (7') aufgeschraubt und zu einem gewählten späteren Zeitpunkt wieder abgeschraubt wird.This is also a method for at least partially detaching or separating a, on a
Erfindungsgemäß wird nun vor dem Aufschrauben der Schraubkappe 7' auf den Hals 3 des Behälters bzw. der Flasche 1 eine Zwischenlage 33 aus einem Thermoplast, einem Klebstoff und/oder einem Siegellack zwischen Deckelabschnitt 8' bzw. dessen Innenfläche 21 und Siegelfolie 14' eingebracht. Sodann wird beim Aufschrauben der Schraubkappe 7' auf den Hals 3 des Behälters 1 die Zwischenlage 25 von der Innenfläche 21 des Deckelabschnitts 8' auf die Siegelfolie 14' gepresst und anschließend die Innenfläche 21 mit der Oberfläche der Siegelfolie 14' verschweißt oder verklebt, derart, daß die Siegelfolie 14' an der Innenfläche 21 fest anhaftet und daß beim Abschrauben der Schraubkappe 7' vom Hals 3 des Behälters bzw. der Flasche 1 die Siegelfolie 14' von der Schraubkappe 7' infolge dieses Anhaftens zumindest teilweise mitgerissen wird.According to the invention, before the screw cap 7 'is screwed onto the
Dabei wird zweckmäßig eine Siegelfolie 14' verwendet, die innerhalb der lichten Weite W des Halses 3 in Umfangsrichtung zumindest abschnittsweise Prägungen oder Perforationen 28 aufweist, die als Sollbruchstellen ausgeführt sind, wobei die Verklebung oder Verschweißung der Innenfläche 21 des Deckelabschnitte 8' mit der Oberfläche der Siegelfolie 14' mit Hilfe der Zwischenlage 25 nur im Bereich der von den Prägungen oder Perforationen 28 umlaufenen Fläche 32 vorgenommen wird.In this case, a sealing film 14 'is expediently used, which has at least partially embossments or
Die Prägungen oder Perforationen verringern den Kraftaufwand für das Aufreißen der Siegelfolie 14' beim Abschrauben der Schraubkappe 7' erheblich.The embossments or perforations reduce the force required for tearing open the sealing film 14 'when unscrewing the screw cap 7' considerably.
Als Siegelfolie 14' wird bei diesem Ausführungsbeispiel ein Plättchen 31 (
Vorzugsweise wird die der Innenfläche 21 des Deckelabschnitts 8' zugewandte Schicht 26 der Siegelfolie 14' innerhalb der lichten Weite W des Halses 3 in Umfangsrichtung (Doppelpfeil Z,
Bei dem gezeigten, bevorzugten, Ausführungsbeispiel ist ferner die Perforation (28) umlaufend kreisförmig.Further, in the preferred embodiment shown, the perforation (28) is circumferentially circular.
Bei einer Schraubkappe 7' zur Ausführung des beschriebenen Verfahrens gemäß dieser zweiten Ausführungsform, wiederum insbesondere aus Kunststoff, mit einem Deckelabschnitt 8' und einem ein Innengewinde 6 aufweisenden Hülsenabschnitt 9" mit einer Aufschrauböffnung 10, zum Aufschrauben auf ein und Abschrauben von einem Außengewinde 4 eines einen Rand 11 aufweisenden Halses 3 einer Flasche 1 od. dergl. aus Kunststoff, Glas od. dergl., der mittels einer an eine kreisringförmige Siegelfläche 12 des Randes 11 des Halses 1 angesiegelten Siegelfolie 14' hermetisch verschlossen wurde, die zum Freigeben eines Flascheninhalts lösbar und/oder zerstörbar ist, besitzt erfindungsgemäß der Deckelabschnitt 8' einen umgekehrt amboßartigen, die Innenfläche 21 aufweisenden, inneren, tafelartigen, Vorsprung 32, derart, daß beim Aufschrauben der Schraubkappe 7' auf den Hals 3 des Behälters 1 od. dergl. die Zwischenlage 33 durch diese Innenfläche 21 zur Anlage an der Oberfläche der Siegelfolie 14' drückbar ist. Dadurch wird eine einwandfreie Verklebung oder Verschweißung und damit ein entsprechendes Anhaften des Deckelabschnitts 8' an der Siegelfolie 14' und ein zuverlässiges Mitreißen der letzteren beim Abschrauben der Schraubkappe 7' ermöglicht.In a screw cap 7 'for carrying out the described method according to this second embodiment, again in particular made of plastic, with a cover portion 8' and a
Es hat sich allgemein als zweckmäßig erwiesen, die Gewindesteigung und die Gewindepaarung 4, 6 derart zu bemessen, daß der Hub der Schraubkappe 7, 70 gegenüber dem Hals 3 etwa 9mm pro Umdrehung der Schraubkappe 7, 70 um 360 Grad beträgt.It has generally proven to be useful, the thread pitch and the
Dabei kann die Ausbildung so getroffen werden, daß das Innengewinde 6 dreigängig ist.The training can be made so that the
Es ist grundsätzlich vorteilhaft, wenn der durch die Gewindesteigung und den Gewindeeingriff der jeweils verwendeten Gewindepaarung 4, 6 aus Außengewinde 4 und Innengewinde 6 in auf den Behälter 1 aufgeschraubter Stellung der Schraubkappe 7, 70 vorgegebene Hub zwischen Schraubkappe 7, 70 und Hals 3 zumindest der Länge des Abtrennmessers 15 bzw. der Abtrennmesser entspricht, wobei diese Länge wiederum zumindest dem radialen Abstand des Innenumfangs 9' des Hülsenabschnitts 9, von dem das Abtrennmesser 15 ausgeht, und einem gedachten Kreis auf der Siegelfläche 12 zwischen Siegelfolie 14 und Rand 11 entspricht.It is basically advantageous if the by the thread pitch and the threaded engagement of the respective used
Vorzugsweise wird der gedachte Kreisumfang vom Innenumfang des Randes (11) des Halses (3) gebildet, derart, daß des Abtrennmesser 15 bzw. die Abtrennmesser die Siegelfläche 12 auf jeden Fall vollständig lösen. Doch ist dies keineswegs immer erforderlich, vielmehr kann es gegebenenfalls auch ausreichen, die Siegelfläche 12 nicht vollständig zu lösen, d. h. die Schneidkante(n) 19 nicht derart weit vordringen zu lassen, sondern nur bis zu dem besagten gedachten Kreis im Bereich der Siegelfläche 12 auf dem Rand 11 des Halses 3, wobei dann das vollständige Ablösen der Siegelfolie 14, 14' mittels ihres Abschälens durch das Anheben der Schraubkappe 7 mit dem dann unter dem Rand der Siegelfolie 14, 14' liegenden Abtrennmesser 15 bzw. mit den dann unter dem Rand der Siegelfolie 14, 14' liegenden Abtrennmessern erfolgt.Preferably, the imaginary circumference of the circumference of the periphery (11) of the neck (3) is formed, such that the
Gemäß einer bevorzugten Ausführungsform der Schraubkappe 70 ist bzw. sind das Abtrennmesser 15 bzw. die Abtrennmesser am Innenumfang 9' des Hülsenabschnitts 9 oberhalb des Innengewindes 6 zum Deckelabschnitt 8 hin angeordnet und der Gewindegang dieses Innengewindes 6 weist Unterbrechungen 71 auf, die bezüglich ihrer Breite u in Umfangsrichtung des Innenumfangs 9' der Breite des Abtrennmessers 15 bzw. der Abtrennmesser im wesentlichen entsprechen oder etwas breiter sind, derart, daß beim Herausnehmen der Schraubkappe 70 nach oben aus der jeweiligen Gießform (nicht gezeigt) das Abtrennmesser 15 bzw. die Abtrennmesser nach unten in diese Unterbrechungen 71 drückbar sind und kurzfristig in denselben Platz finden, bis sie aus der Form austreten und frei werden.According to a preferred embodiment of the
Diese Ausgestaltung mit den Unterbrechungen 71 ermöglicht eine erhebliche Einsparung an Bauhöhe der Schraubkappe 70 und damit Kunststoffmaterial, da die Abtrennmesser 15 dadurch näher am Innengewinde 6 angeordnet werden können, und vermeidet gleichzeitig Probleme mit der Entnahme der Schraubkappe 70 aus ihrer Form, in der sie insbesondere bei der bevorzugten Verwendung von Kunststoff spritzgegossen worden ist. Ohne die Unterbrechungen 71 muß die Bauhöhe einer Schraubkappe zwangsläufig größer sein, weil bei der Entnahme derselben aus der Gießform die Abtrennmesser 15 nun einmal zwangsläufig nach unten klappen und dabei ohne die Unterbrechungen 71 vollständig oberhalb der Gewindegänge Platz finden müssen.This embodiment with the
Ferner wird es bevorzugt, daß das Abtrennmesser 15 bzw. die Abtrennmesser jeweils (ein) die Schneidkante(n) aufweisende(s) freie(s) Ende(n) besitzen, das bzw. die beim Angriff an der Siegelfläche 12 zwischen Siegelfolie 14 und Rand 11 eine Krümmung oder Knickung auf den Rand 11 zu aufweist bzw. aufweisen (besonders deutlich aus den
Bevorzugt wird eine Ausführungsform, bei der das freie Ende bzw. die freien Enden des Abtrennmessers 15 bzw. der Abtrennmesser zusätzlich nach beiden Seiten gebogen ist bzw. sind, derart, daß es bzw. sie eine dem Rand 11 zugewandte löffelartig konkave Wölbung aufweist bzw. aufweisen (nicht gezeigt). Es hat sich herausgestellt, daß eine solche Form der Abtrennmesserenden eine besonders gute Funktion beim Abtrennen der Siegelfolie 14 erbringt, da sie sich beim Eindringen in die Siegelfläche 12 elastisch abflacht und durch die ihr innewohnenden Rückstellkräfte zusätzlich zu der vorhandenen Keilwirkung eine Trennkraft senkrecht zu ihrer Fläche nach oben und nach unten bzw. einerseits auf die Siegelfolie 14 und andererseits auf den Rand 11 ausübt.Preference is given to an embodiment in which the free end or the free ends of the
Schließlich kann die Schraubkappe 70 auch noch an der Innenseite des Deckelabschnitts 8 zwischen mindestens einer konzentrisch umlaufenden, hier relativ kurzen, d. h. eine geringe Höhe aufweisenden, Andrucklippe 23 und der Innenwand 9' des Hülsenabschnitts 9 eine umlaufende Gegendrucklippe 72 (
Dabei ist zu betonen, daß dieser Umfangsbereich 13 nicht unbedingt über den Rand 11 des Halses 3 überstehen muß. Er muß auch nicht unbedingt eine nicht verklebte bzw. nicht versiegelte umlaufende Kante besitzen, um ein einwandfreies Untergreifen seitens der Schneidkante(n) 19 des bzw. der Abtrennmesser(s) 15 zu gewährleisten. Die diesbezügliche jeweilige Ausgestaltung nach der Erfindung ist von den im Einzelfall jeweils gegebenen Parametern abhängig, von denen nur beispielsweise das Material der Schraubkappe selber, das Material der Siegelfolie 14, das Material des verwendeten Bindemittels und die Elastizität des bzw. der Abtrennmesser(s) genannt werden sollen. Bei der Schraubkappe 70 wird ja beispielsweise kein Verstärkungsplättchen 22 für eine dies gegebenenfalls nötig habende Siegelfolie 14 verwendet, wie dies bei vorhergehenden Ausführungsformen beschrieben ist, weshalb die Gegendrucklippe 72 hier vorteilhaft ist.It should be emphasized that this
