Abstract
Description
Schraubverschluss mit einer Schneidehülse Screw cap with a cutting sleeve
Die vorliegende Erfindung betrifft einen Schraubverschluss, umfassend einen Unterteil mit einem zylindrischen Rohrabschnitt mit Gewinde und einem endständigen Flansch zur Befestigung auf einem geschlossenen Behälter aus Folienmaterial, und einer mit dem Gewinde des Unterteiles schraubverbundene Schneidehülse. Schraubverschlüsse der eingangs genannten Art sind bereits seit Ende der 80er Jahre bekannt. Ein solcher Verschluss zeigt beispielsweise die EP 0328652 A. Weiterentwicklungen davon zeigen beispielsweise die US 5147070, die WO 99/62776, die WO 2004/083055 und viele weitere. Bei Verschlüssen dieser Art wird die Schneidehülse von Mitnehmern getrieben, die an der Unterseite der Deckfläche der Schraubkappe angebracht sind. Schraubt man diese Schraubkappe auf, so wird gleichzeitig die Schneidehülse in eine gleichsinnige Drehbewegung mit entgegengesetzter achsialer Verschiebung bewegt. Hierbei schneidet die Schneidehülse den geschlossenen Behälter auf, wobei eine kombinierte Perforation und Schneidwirkung einsetzt. Verschlüsse dieser Art haben sich auf dem Markt durchgesetzt und sind heute auf geschlossenen Behältnissen aus Folienmaterial nicht mehr wegzudenken. Diese Behältnisse waren bisher im wesentlichen aus laminiertem Folienmaterial gefertigt, die aus einer Kombination aus Kunststofffolien, Kartonlagen, einer Aluminiumsperrschicht und einer inneren versiegelnden Schicht aus Kunststofffolie bestehen. Behältnisse aus solchem mehrschichtigem Folienmaterial sind relativ druckfest und wurden bisher zur Hauptsache auf dem Getränkemarkt eingesetzt. The present invention relates to a screw cap comprising a base having a threaded cylindrical tubular portion and a terminal flange for attachment to a closed container of sheet material and a cutting sleeve threadedly connected to the thread of the base. Screw caps of the type mentioned are already known since the late 80s. Such a closure is shown, for example, in EP 0 328 652 A. Further developments thereof are shown, for example, by US Pat. No. 5,147,070, WO 99/62776, WO 2004/083055 and many others. In closures of this type, the cutting sleeve is driven by drivers, which are attached to the underside of the top surface of the screw cap. When screwing on this screw cap, at the same time the cutting sleeve is moved in a same direction rotational movement with opposite axial displacement. Here, the cutting sleeve cuts the closed container, using a combined perforation and cutting action. Closures of this type have prevailed in the market and are today an integral part of closed containers made of film material. These containers were heretofore essentially made of laminated film material consisting of a combination of plastic films, cardboard layers, an aluminum barrier layer and an inner sealing layer of plastic film. Containers of such multilayer film material are relatively pressure resistant and have been used mainly for the beverage market.
Erst in neuerer Zeit werden Behältnisse aus reinem Kunststofffolienmaterial gefertigt, die wesentlich flexibler sind und entsprechend druckempfindlich. Daher lassen sich in solchen Behältnissen nun nicht nur Getränke verpacken, sondern auch hochviskose Flüssigkeiten, thixotrope Flüssigkeiten oder rieselfähige Feststoffe. Solche Inhalte lassen sich zwar dosiert abgeben, indem man bei offenem Verschluss auf das Behältniss einen Druck ausübt und damit das Innenraumvolumen reduziert. Eine kontrollierte dosierte Abgabe lässt sich aber nur schwer erreichen. Insbesondere wenn dass Behältniss noch praktisch vollständig voll ist, muss man dieses anheben und dabei wird automatisch je nach Gewicht des gefüllten Behälters ein mehr oder weniger starker Druck auf diesen ausgeübt. Da bei den bisher bekannten Schraubverschlüssen mit Schneidehülse die Schraubkappe vollständig abgeschraubt wird, ist der volle Durchgang der Schneidehülse offen und die Gefahr, dass dabei die Flüssigkeit allein schon beim Anheben des Behältnisses überschwappt, ist enorm gross. Only in recent times containers are made of pure plastic film material, which are much more flexible and pressure sensitive accordingly. Therefore, can be packed in such containers not only drinks, but also highly viscous liquids, thixotropic liquids or free-flowing solids. Although such contents can be delivered in a metered manner by applying pressure to the container when the closure is open and thus reducing the volume of the interior space. Controlled dosed delivery is difficult to achieve. In particular, if the container is still practically completely full, you have to raise this and it is automatically depending on the weight of the filled container a more or less strong pressure exerted on this. Since in the previously known screw caps with cutting sleeve, the screw cap is completely unscrewed, the full passage of the cutting sleeve is open and the risk that it will spill over the liquid alone when lifting the container is enormous.
Auf dem Markt sind auch eine Vielzahl von unterschiedlichsten Formen von Dosierverschlüssen vorhanden, die eine Dosieröffnung aufweisen, bei denen die Dosieröffnung entsprechend mehr oder weniger stark geöffnet beziehungsweise verschlossen werden kann oder aber bei denen der Zugang zur Dosieröffnung beispielsweise mit einem Ventilkolben mehr oder weniger geöffnet werden kann. On the market, a variety of different forms of Dosierverschlüssen are present, which have a metering, in which the metering can be opened or closed according to more or less or in which the access to the metering, for example, with a valve piston more or less open can.
Schraubverschlüsse der eingangs genannten Art, die eine Schneidehülse aufweisen mit denen der Behälter auf dem der Schraubverschluss angebracht ist, aufgeschnitten und damit geöffnet werden kann, sind bisher, mit Dosierverschluss versehen, nicht bekannt. Es ist nunmehr die Aufgabe der vorliegenden Erfindung hier Abhilfe zu schaffen. Screw caps of the type mentioned, which have a cutting sleeve with which the container is mounted on the screw, cut open and thus can be opened, so far, provided with dosing, not known. It is now the object of the present invention to remedy this situation.
Diese Aufgabe löst ein Schraubverschluss der eingangs genannten Art, bei dem die Schneidehülse den Unterteil überragt und in diesem überragenden Bereich eine seitliche Dosieröffnung, sowie ein Innengewinde in dem ein die seitliche Dosieröffnung schliessender und öffnender Ventilkolben vorhanden ist, der in dem Bereich unterhalb der seitlichen Dosieröffnung dichtend in die Schneidhülse eingreift . This object is achieved by a screw cap of the type mentioned, in which the cutting sleeve projects beyond the lower part and in this projecting area a lateral metering opening, and an internal thread in which the lateral metering opening closing and opening valve piston is present, in the area below the lateral metering opening engages sealingly in the cutting sleeve.
Ein derartiger Schraubverschluss wird bevorzugterweise so ausgestaltet, dass die Schneidehülse unterhalb der seitlichen Dosieröffnung doppelwandig gestaltet ist mit einer gewindefreien inneren Mantelwand mit einer endständigen Schneidkante und einer äusseren Mantelwand mit Innengewinde, welche mit dem Gewinde am Unterteil kämmt, und dass die äussere Mantelwand in achsialer Richtung kürzer ist als die Höhe des zylindrischen Rohrabschnittes des Unterteiles. Hierdurch lässt sich nun die Schneidehülse von aussen fassen und von Hand unabhängig von der Schraubbewegung einer Schraubkappe betätigen. Während man somit hierdurch den Behälter aufschneiden kann während gleichzeitig der Verschluss noch geschlossen ist, besteht auch nicht die Gefahr während dieser Öffnung bereits Flüssigkeit aus dem Behälter hinauszuquetschen. Such a screw cap is preferably designed so that the cutting sleeve is designed double-walled below the lateral metering with a thread-free inner shell wall with a terminal cutting edge and an outer shell wall with internal thread, which meshes with the thread on the lower part, and that the outer shell wall in the axial direction shorter than the height of the cylindrical pipe section of the lower part. As a result, now the cutting sleeve can be taken from the outside and operated by hand, regardless of the screwing a screw cap. Thus, while you can thereby cut open the container while the shutter is still closed, there is also no danger during this opening already squeeze out liquid from the container.

Figur 4 dieselbe Ansicht des Verschlusses in der maximal geöffneten Position. Der selbstöffnende Schraubverschluss ist gesamthaft mit 1 bezeichnet. Allerdings könnte man denselben Verschluss ebenso gut als Dosierverschluss bezeichnen, da es sich hierbei um die Kombination eines selbstöffnenden Schraubverschlusses und eines Dosierverschlusses handelt. Der erfindungsgemässe Schraubverschluss besteht aus vier Bauteilen, nämlich einem Unterteil 2, einer Schneidehülse 3, einem Distanzhaltemittel 4 und einem Ventilkolben 5, der im obersten Bereich als Drehgriff gestaltet ist, wobei im zusammengebauten Zustand nur dieser Teil des Ventilkolbens sichtbar ist. Der hier interessierende Schraubverschluss wird, wie bereits eingangs erwähnt, auf einem aus Folie gefertigten geschlossenen Behälter befestigt. Hierzu weist der Unterteil 2 einen radial nach aussen vorstehenden, umlaufenden Flansch 21 auf. Die Schneidehülse 3 besitzt eine seitliche Dosieröffnung 31, die hier relativ gross als quadratisches Fenster realisiert ist. Vor der Erstbenutzung ist das Distanzhaltemittel 4 noch vorhanden, welches entweder als Distanzring oder als Garantieband 40 realisiert sein kann. Vom Ventilkolben ist hier einerseits die endständige Deckfläche 52 und andererseits die umlaufende, die Schneidehülse im oberen Bereich übergreifende Schürze 53 erkennbar, die als Grifffläche dient und entsprechend mit einer Rippung 54 versehen ist. Figure 4 shows the same view of the closure in the maximum open position. The self-opening screw cap is designated overall by 1. However, one could call the same closure as well as dosing, as this is the combination of a self-opening screw cap and a Dosierverschlusses. The inventive screw cap consists of four components, namely a lower part 2, a cutting sleeve 3, a spacer means 4 and a valve piston 5, which is designed in the uppermost region as a rotary handle, wherein in the assembled state, only this part of the valve piston is visible. The interest here screw is, as already mentioned, attached to a closed container made of foil. For this purpose, the lower part 2 has a radial outwardly projecting, circumferential flange 21. The cutting sleeve 3 has a lateral metering opening 31, which is realized here relatively large as a square window. Before the first use of the distance-holding means 4 is still present, which can be realized either as a spacer ring or as a guarantee strip 40. From the valve piston here on the one hand, the terminal top surface 52 and on the other hand, the circumferential, the cutting sleeve in the upper region cross skirt 53 can be seen, which serves as a grip surface and is provided with a ribbing 54 accordingly.
Nachfolgend werden nun die einzelnen Teile dieses Schraubverschlusses mit Bezug auf die Figur 2 im Detail beschrieben. The individual parts of this screw cap will now be described in detail with reference to FIG.
Der Unterteil 2 besteht aus einem Rohrabschnitt 20 an dem unten endständig ein radial nach aussen gerichteter Flansch 21 angeformt ist. Auf der Aussenseite des Rohrabschnittes 20 ist ein Aussengewinde 22 angebracht. Der Unterteil 2 kann auf den geschlossenen Behälter aufgeklebt oder aufgeschweisst sein. Insbesondere wenn es sich beim geschlossenen Behälter um einen Schlauchbeutel aus Kunststofffolie handelt, wird man bevorzugterweise den Unterteil 2 auf diesen Schlauchbeutel aufschweissen . Dies erfolgt üblicherweise mit einer Ultraschallschweissung . Über den Rohrabschnitt 20 des Unterteiles 2 kann nun ein Distanzmittel 4 geschoben werden, welches ungefähr den Abstand zwischen dem Flansch 21 und dem Aussengewinde 22 überbrückt. Im hier dargestellten Beispiel ist das Distanzhaltemittel 4 ein Distanzring der unter leichter Dehnung über das Aussengewinde hinweg geschoben werden kann. Vor der Erstöffnung muss dieser Distanzring 40 entfernt werden. Hierzu ist eine Reisslasche 41 angeformt. The lower part 2 consists of a pipe section 20 at the bottom end a radially outwardly directed flange 21 is integrally formed. On the outside of the pipe section 20, an external thread 22 is attached. The lower part 2 may be glued or welded onto the closed container. In particular, when the closed container is a tubular bag made of plastic film, it is preferable to weld the lower part 2 onto this tubular bag. This is usually done with an ultrasonic welding. About the pipe section 20 of the lower part 2 can now be a spacer means 4 are pushed which approximately bridges the distance between the flange 21 and the external thread 22. In the example shown here, the spacer holding means 4 is a spacer ring which can be pushed over the external thread with slight elongation. Before the first opening of this spacer ring 40 must be removed. For this purpose, a tear flap 41 is formed.
Als nächstes schraubt man nun die Schneidehülse 3 auf. Die Schneidehülse 3 besteht aus einem beidseitig offenen Zylinder 30 mit einer seitlichen Dosieröffnung 31. Der Bereich oberhalb der Dosieröffnung 31 wird hier als Ventilzylinderbereich bezeichnet. Unterhalb der Dosieröffnung 31 ist die Schneidehülse 3 doppelwandig . Dieser doppelwandige Bereich ist mit 33 bezeichnet. Die innere Mantelwand, die hier nicht ersichtlich ist, stellt die lineare Fortsetzung des Ventilzylinderbereiches 32 dar. Diese innere Mantelwand 35 weist am unteren Ende Schneidemittel 38 auf, mittels denen der geschlossene Behälter, auf dem der Verschluss angebracht ist, aufgeschnitten werden kann. Vor der Erstbenutzung des Schraubverschlusses liegen diese Schneidemittel 38 vollständig im Bereich des Rohrabschnittes 20 des Unterteiles 2. In der Figur 2 ist vom doppelwandigen Bereich 33 insbesondere die äussere Mantelwand 34 erkennbar. Diese äussere Mantelwand 34 läuft konzentrisch um die innere Mantelwand 35. Die äussere Mantelwand 34 besitzt ein in dieser Figur nicht erkennbares Innengewinde 36, welches passend zum Aussengewinde 22 des Unterteiles 2 ist. Der Distanzring 40 stellt sicher, dass vor der Erstbenützung die Schneidemittel 38 nicht unbeabsichtigt mit dem Behälter in Kontakt kommen können. Erst wenn dieser Distanzring 40 entfernt worden ist, lässt sich die Schneidehülse 3 schraubbeweglich abwärts bewegen und damit den noch geschlossenen Behälter öffnen. Hierzu dreht man die Schneidehülse 3 im Uhrziegersinn abwärts. Der doppelwandige Bereich dient hierbei als Grifffläche. In der Figur 2 ebenfalls nicht ersichtlich ist das Innengewinde im Ventilzylinderbereich 32. Next, you now screwed on the cutting sleeve 3. The cutting sleeve 3 consists of a cylinder 30 which is open on both sides and has a lateral metering opening 31. The area above the metering opening 31 is referred to herein as the valve cylinder area. Below the metering opening 31, the cutting sleeve 3 is double-walled. This double-walled area is designated 33. The inner jacket wall, which is not visible here, represents the linear continuation of the valve cylinder region 32. This inner jacket wall 35 has at the lower end cutting means 38, by means of which the closed container, on which the closure is mounted, can be cut open. Before the first use of the screw cap, these cutting means 38 lie completely in the region of the tube section 20 of the lower part 2. In FIG. 2, the outer jacket wall 34 can be seen in particular from the double-walled region 33. This outer jacket wall 34 runs concentrically around the inner jacket wall 35. The outer jacket wall 34 has an internal thread 36 which is not recognizable in this figure and which is suitable for the external thread 22 of the lower part 2. Of the Spacer ring 40 ensures that prior to initial use, the cutting means 38 can not inadvertently come into contact with the container. Only when this spacer ring 40 has been removed, the cutting sleeve 3 can move downwardly screwed and thus open the still closed container. To do this, turn the cutting sleeve 3 clockwise downward. The double-walled area serves as a grip surface. Also not visible in FIG. 2 is the internal thread in the valve cylinder region 32.
Der Ventilkolben 5 ist als Hohlzylinder 55 gestaltet und weist an seinem oberen Ende ein Aussengewinde 56 auf, welches mit dem Innengewinde 39 der Schneidhülse zusammenpasst . Der Hohlzylinder 55 des Ventilkolbens 5 besitzt eine umlaufende Anschlaglippe 51 die sicherstellt, dass der Ventilkolben 5 nicht vollständig aus der Schneidehülse 3 hinausgeschraubt werden kann. In der maximal offenen Position schlägt diese umlaufende Anschlaglippe 51 an der oberen Kante der seitlichen Dosieröffnung an. Zudem kann auf derselben Höhe in der Schneidehülse 3 eine umlaufende Nut vorhanden sein, in der die Anschlaglippe in der obersten Position einrastet. Mit Verweis auf die Figuren 3 und 4 wird nun nochmals die Funktion des erfindungsgemässen Schraubverschlusses erläutert. Nachdem nun der Schraubverschluss in der Reihenfolge wie in der Explosionszeichnung nach Figur 2 zusammengesetzt worden ist, wird der zusammengebaute Schraubverschluss auf der Folie eines Schlauchbeutels mittels einer Sonotrode die auf den Flansch 21 aufliegt, aufgeschweisst . Vor der Erstöffnung wird dann das Distanzhaltemittel 4 entfernt und der Benutzer ergreift die äussere Mantelwand 34 und schraubt nun die Schneidehülse 3 abwärts bis die äussere Mantelwand 34 auf dem Flansch 21 aufliegt. Hierbei schraubt sich das Schneidemittel 38 abwärts, durchstösst die Folie des Behälters und schneidet diese Folie bis auf einen Restbereich zu einer Rondelle aus, die dabei gleichzeitig zur Seite verdrängt wird. Unterhalb des Gewindes kann ein nockenartig, nach aussen vorstehendes Arretiermittel 23 vorgesehen sein. Gleichzeitig kann zusätzlich am unteren Rand der äusseren Mantelwand 34 eine nach innen ragende Haltenase 34' angeformt sein, die unter diesem nockenartigen Arretiermittel 23 einrastet und damit nachdem Erstgebrauch diese Relativposition der Schneidehülse 3 relativ zum Unterteil 2 sichert. Diese in der Figur 3 dargestellte Position bildet nun die geschlossene Gebrauchsposition. Hierbei ragt nun der Hohlzylinder 55 des Ventilkolbens 5 in den Bereich des beidseitigen offen Zylinders 30 unterhalb der Dosieröffnung 31 hinein. Eine umlaufende Dichtwulst 37 drückt dabei dichtend auf den untersten Bereich des Hohlzylinders 55. Der Benutzer kann nun die Grifffläche der Schütze 53 fassen und den Ventilkolben 5 nach oben drehen. Hierbei läuft das Aussengewinde 56 am Hohlzylinder 55 im Innengewinde 39 der Schneidehülse 3 oberhalb der Dosieröffnung 31. Unterhalb von diesem Innengewinde 39, aber oberhalb der Dosieröffnung 31, ist an der Schneidehülse 3 ein nach innen gerichteter umlaufender Dichtwulst 60 angebracht. Der Ventilkolben 5 lässt sich soweit nach oben drehen, bis die umlaufende Anschlaglippe 51 an der Oberkante der Dosieröffnung 31 zum anliegen kommt. Im hier dargestellten Beispiel ist auch der Dosieröffnung 31 diametral gegenüberliegend eine geschlossene Ausformung 61 vorgesehen. Diese geschlossene Ausformung 61 wird gebildet durch die in achsialer Richtung verlängerte äussere Mantelwand 34 an der auf der Höhe der Oberkante der Dosieröffnung 31 eine nach innen gerichtete Schulter 62 die Verbindung dieser äusseren Mantelwand mit dem oberen Bereich des beidseitig offenen Zylinders 30 hergestellt ist. The valve piston 5 is designed as a hollow cylinder 55 and has at its upper end an external thread 56 which mates with the internal thread 39 of the cutting sleeve. The hollow cylinder 55 of the valve piston 5 has a circumferential stop lip 51 which ensures that the valve piston 5 can not be completely unscrewed out of the cutting sleeve 3. In the maximum open position, this circumferential abutment lip 51 abuts against the upper edge of the lateral metering opening. In addition, at the same height in the cutting sleeve 3, a circumferential groove may be present, in which the stopper lip engages in the uppermost position. With reference to Figures 3 and 4, the function of the screw cap according to the invention will now be explained again. Now that the screw cap in the Sequence as in the exploded view of Figure 2 has been assembled, the assembled screw cap on the film of a tubular bag by means of a sonotrode which rests on the flange 21, welded. Before the initial opening, the distance-holding means 4 is removed and the user grips the outer jacket wall 34 and now screws the cutting sleeve 3 downwards until the outer jacket wall 34 rests on the flange 21. In this case, the cutting means 38 screws downwards, pierces the film of the container and cuts this film except for a residual area to a Rondelle, which is displaced simultaneously to the side. Below the thread, a cam-like, outwardly projecting locking means 23 may be provided. At the same time, in addition to the lower edge of the outer jacket wall 34 an inwardly projecting retaining lug 34 'be formed, which engages under this cam-like locking means 23 and thus after first use this relative position of the cutting sleeve 3 secures relative to the lower part 2. This position shown in FIG. 3 now forms the closed use position. In this case, the hollow cylinder 55 of the valve piston 5 projects into the area of the open-sided, open-ended cylinder 30 below the metering opening 31. A circumferential sealing bead 37 presses sealingly on the lowermost region of the hollow cylinder 55. The user can now grasp the gripping surface of the contactors 53 and turn the valve piston 5 upwards. In this case, the external thread 56 runs on the hollow cylinder 55 in the internal thread 39 of the cutting sleeve 3 above the metering opening 31. Below this internal thread 39, but above the metering opening 31, an inwardly directed circumferential sealing bead 60 is attached to the cutting sleeve 3. The valve piston 5 can be turned upwards until the circumferential abutment lip 51 abuts the upper edge of the metering opening 31. In the example shown here, the metering opening 31 diametrically opposite a closed formation 61 is provided. This closed formation 61 is formed by the axially extended outer shell wall 34 at the level of the upper edge of the metering 31, an inwardly directed shoulder 62, the connection of this outer shell wall is made with the upper portion of the cylinder 30 open on both sides.
Statt der geschlossenen Ausformung 61 kann die äussere Mantelwand 34 auch generell und umlaufend hochgezogen sein bis zur genannten Schulter 62, die auf der Höhe der Oberkante der Dosieröffnung verläuft. Dies ist jedoch nicht geeignet, da in diesem Falle beim Verschliessen ein Restvolumen unterhalb dieser Schulter 62 bestehen würde aus dem eine doch noch erhebliche Restmenge nach dem Verschliessen nachströmen würde. Bei der hier gewählten geschlossenen Ausformung 61 kann ein solches Nachströmen nicht stattfinden. Auch Spritzgusstechnisch lässt sich die hier gezeigte bevorzugteInstead of the closed formation 61, the outer jacket wall 34 can also be raised generally and peripherally up to said shoulder 62 which extends at the level of the upper edge of the metering opening. However, this is not suitable, since in this case a residual volume would exist below this shoulder 62 when closing, from which a considerable amount of residue would still flow after closure. In the case of the closed configuration 61 selected here, such an afterflow can not take place. Also In terms of injection molding technology, the one shown here is preferred
Ausführungsform mit der Dosieröffnung 31 diametral gegenüberliegenden geschlossenen Ausführung 61 mit einem einzigen seitlichen Schieber realisieren. Embodiment with the metering 31 realize diametrically opposed closed design 61 with a single lateral slide.
