Description

kocher-plastik Maschinenbau GmbH, Talstr. 22-30, 74429 Sulzbach-Laufen BEHÄLTER MIT EINSTÜCKIGEM KOPFTEIL  kocher-plastik Maschinenbau GmbH, Talstr. 22-30, 74429 Sulzbach-Laufen CONTAINER WITH ONE PIECE HEAD PIECE
Die Erfindung betrifft einen Behälter, insbesondere aus einem Kunststoffmaterial bestehend und nach einem Blasform-, Füll- und Siegelverfahren hergestellt, mit einem Behälterkörper zur Aufnahme eines Fluids und einem an den Behälterkörper sich anschl ießenden Halsteil, das an seinem freien Ende eine Abgabeöffnung für das Fluid aufweist, die über einen Trennbereich mit einem Kopfteil verschlossen ist, das mittels Betätigen eines bewegbaren Hülsenteils durch Lösen des Trennbereichs zur Freigabe der Abgabeöffnung vom Halsteil abnehmbar ist. Kunststoffbehälter, die in einem Blasform-, Füll- und Siegelverfahren (BFS- Verfahren) hergestellt sind, wie es beispielsweise in EP 2 269 558 A1 beschrieben und in der Fachwelt auch unter der Bezeichnung„bottelpack®- System" bekannt ist, werden für Lebens- und Genussmittel sowie in der Medizin mit großem Vorteil zur Verpackung von Pharmazeutika, Diagnos- tika, enteraler Ernährung und Medizinprodukten, z.B. Spül- und Dialyselösungen und dergleichen eingesetzt. Die einteilige Ausbildung des Behälterhalsteils und des die Entnahmeöffnung am Halsteil verschließenden Kopfteils im Blasformverfahren hat den Vorteil, dass der Behälterinhalt ausschließlich Kontakt zu einem das Behältermaterial bildenden Polymer hat, typischerweise einem Kunststoff wie LDPE, HDPE oder PP. Dadurch lässt sich bei derart hergestellten und gefüllten Behältern die Keimarmut/Sterilität des Behälterinhalts für längere Zeiträume gewährleisten. Der Trennbereich, über den das Kopfteil an das Halsteil angeformt ist, ist bei derartigen Behältern als Sollbruchstelle ausgeführt, an der das Kopfteil für einen Entnahmevorgang vom Halsteil lösbar ist. Um dem Benutzer ein sicheres und bequemes Lösen des Trennbereichs zu ermöglichen, ist aus der US 4 1 76 755 bereits ein Behälter der eingangs genannten Gattung bekannt, der als Öffnungs- oder Aufreißhilfe ein Betätigungselement in Form eines vom Benutzer betätigbaren Hülsenteils aufweist, das in seiner Bereitschaftsposition das Halsteil und zumindest Teile des Kopfteils in der Art eines Außenringes umgibt, der vom Benutzer betätigbar ist und in einem betätigten Zustand den Trennbereich durch Aufreißen der Sollbruchstelle löst. The invention relates to a container, in particular made of a plastic material and produced by a blow molding, filling and sealing process, comprising a container body for receiving a fluid and a subsequent to the container body eschenden Halsteil, which at its free end a discharge opening for the fluid which is closed by a separating portion having a head portion which is detachable by operating a movable sleeve member by releasing the separating portion for releasing the discharge port from the neck portion. Plastic containers which are produced in a blow molding, filling and sealing process (BFS process), as described, for example, in EP 2 269 558 A1 and also known in the art under the name "bottelpack® system", are used for food - And stimulants and in medicine with great advantage for packaging of pharmaceuticals, diagnostics, enteral nutrition and medical devices, eg rinsing and dialysis solutions and the like used. The one-piece design of the container neck and the removal opening on the neck part occluding head part in the blow molding has the Advantage that the contents of the container have exclusive contact with a polymer forming the container material, typically a plastic such as LDPE, HDPE or PP, thus ensuring the germ reduction / sterility of the container contents for longer periods in containers produced and filled in this way. The separation area over which the head part is formed on the neck part, is carried out in such containers as a predetermined breaking point at which the head part for a removal operation from the neck portion is solvable. In order to allow the user a safe and comfortable release of the separation area, a container of the type mentioned is already known from US 4 1 76 755, which has as an opening or Aufreißhilfe an actuating element in the form of a user operable sleeve part in his Standby position surrounding the neck portion and at least parts of the head part in the manner of an outer ring, which is operable by the user and in an actuated state releases the separation area by tearing the predetermined breaking point.
Ausgehend von diesem Stand der Technik stellt sich die Erfindung die Auf- gäbe, einen Behälter dieser Gattung im Hinblick auf besonders gute Gebrauchseigenschaften weiter zu verbessern. Based on this state of the art, the invention has the task of further improving a container of this type with regard to particularly good service properties.
Erfindungsgemäß ist diese Aufgabe durch einen Behälter gelöst, der die Merkmale des Patentanspruchs 1 in seiner Gesamtheit aufweist. According to the invention this object is achieved by a container having the features of claim 1 in its entirety.
Eine wesentliche Besonderheit der Erfindung besteht demgemäß darin, dass das Hülsenteil vom unbetätigten Zustand bis zum den Trennbereich lösenden betätigten Zustand zumindest teilweise in Anlage an einer Führungsbahn geführt ist, die Teil des abzutrennenden Kopfteils ist. Dadurch wird erreicht, dass das Hülsenteil koaxial zum Kopfteil ausgerichtet ist, so dass eine gegenüber dem erwähnten Stand der Technik gleichmäßigere Belastung des Trennbereichs beim Lösen erreicht wird. Auch bei Entnahmeöffnungen verhältnismäßig großen Öffnungsdurchmessers mit einem entsprechend ausgedehnten Trennbereich wird dadurch ein sicherer Abreißvor- gang über den gesamten Umfang der Entnahmeöffnung gewährleistet. In vorteilhafter Weise können zum Betätigen des Hülsenteils ein am Halsteil angeordnetes Außengewinde und ein mit diesem in Eingriff bringbares Innengewinde am Hülsenteil vorgesehen sein, wobei mit Aufschrauben des Hülsenteils der Trennbereich unter Freigabe der Abgabeöffnung lösbar ist. Mittels eines Schraubvorgangs lassen sich auf besonders bequeme Weise verhältnismäßig hohe Betätigungskräfte erzeugen, so dass sich die Handhabung des erfindungsgemäßen Behälters für den Benutzer besonders bequem und mühelos gestaltet. Mit besonderem Vorteil kann die Anordnung so getroffen sein, dass bei Aufschrauben des Hülsenteiis der Trennbereich dadurch lösbar ist, dass eine Anlageschulter des Hülsenteils unter Anlage mit dem Kopfteil dieses zum Lösen des Trennbereichs mitnimmt. Bei besonders vorteilhaften Ausführungsbeispielen weist das Hülsenteil an seiner freien Stirnseite flexible Anlagefinger auf, die mit Aufschrauben des Hülsenteils in Untergriff mit einem Vorsprung am Kopfteil kommen. A significant feature of the invention accordingly is that the sleeve part is guided from the unactuated state to the separation area releasing actuated state at least partially in contact with a guideway which is part of the separated head part. This ensures that the sleeve part is aligned coaxially with the head part, so that a relation to the mentioned prior art uniform loading of the separation area is achieved during release. Even with removal openings of relatively large opening diameter with a correspondingly extended separation area, this ensures a secure tear-off operation over the entire circumference of the removal opening. In an advantageous manner, an external thread arranged on the neck part and an internal thread which can be brought into engagement with the sleeve part can be provided on the sleeve part for actuating the sleeve part, it being possible to detach the release region releasing the discharge opening by screwing on the sleeve part. By means of a screwing operation, relatively high actuating forces can be generated in a particularly convenient manner, so that the handling of the container according to the invention is particularly convenient and effortless for the user. With particular advantage, the arrangement can be made such that upon screwing the Hülsenteiis the separation area is thereby solved that a contact shoulder of the sleeve part under engagement with the head part this entrains to release the separation area. In particularly advantageous embodiments, the sleeve part on its free end side on flexible bearing fingers, which come with screwing of the sleeve part in the lower handle with a projection on the headboard.
Dadurch ist das Hülsenteil durch teilweises Aufschrauben in eine Bereitschaftsposition bringbar, bei der das Hülsenteil durch Einschnappen der Anlagefinger am Kopfteil gesichert, jedoch relativ zu diesem verdrehbar ist. Nach Durchführen eines Entnahmevorgangs durch weiteres Aufschrauben des Hülsenteils nehmen die Anlagefinger bei sich anschließendem Abschrauben des Hülsenteils das vom Trennbereich abgelöste Kopfteil mit, das nach Abnehmen des Hülsenteils an diesem unverlierbar gesichert ist. As a result, the sleeve part can be brought into a ready position by partially screwing it on, in which the sleeve part is secured by snapping the bearing fingers on the head part, but is rotatable relative thereto. After performing a removal operation by further screwing the sleeve part take the investment fingers in subsequent unscrewing of the sleeve part with the detached part of the separation headboard, which is secured captive after removing the sleeve part at this.
Um dem Benutzer die Möglichkeit zu geben, einen Entnahmevorgang sowohl durch Aufschrauben als auch durch Abschrauben des Hülsenteils durchzuführen, kann die Anordnung so getroffen sein, dass durch Abschrauben des Hülsenteils bei nicht gelöstem Trennbereich die Anlagefin- ger in Untergriff mit dem Vorsprung des Kopfteils dieses unter Lösen des Trennbereichs mitnehmen. Mit besonderem Vorteil kann die Führungsbahn für die Betätigungsbewegungen des Hülsenteils an der Außenseite eines das Kopfteil umgreifenden Ringbundes gebildet sein, der sich zwischen dem Trennbereich und einer Ringnut erstreckt, die am Kopfteil den Raum für die Aufnahme der Anlage- finger bildet. Dadurch steht eine Begrenzungswand der Ringnut als vollumfänglicher Vorsprung für die Abstützung der Anlagefinger zur Verfügung. Dabei kann der Außendurchmesser des Ringbundes dem Innendurchmesser des Halsteils im Bereich von dessen Außengewinde entsprechen, und der Ringbund kann eine axiale Erstreckung aufweisen, deren Länge der axialen Länge der Ringnut, gemessen über ihre kleinste Durchmesserweite, entspricht. In order to give the user the opportunity to perform a removal operation by both unscrewing and by unscrewing the sleeve part, the arrangement may be such that by unscrewing the sleeve part in unresolved separation area the Anlagefin- ger in under-grip with the projection of the head part of this under Take the release of the separation area with you. With particular advantage, the guide track for the actuation movements of the sleeve part can be formed on the outside of an annular collar encompassing the head part, which extends between the separating area and an annular groove which forms the space for receiving the bearing fingers on the head part. As a result, a boundary wall of the annular groove is available as a fully circumferential projection for the support of the bearing fingers. In this case, the outer diameter of the annular collar corresponding to the inner diameter of the neck portion in the region of the outer thread, and the annular collar may have an axial extent whose length corresponds to the axial length of the annular groove, measured over its smallest diameter.
Bei besonders vorteilhaften Ausführungsbeispielen liegt bei einem Untergriff der Anlagefinger des Hülsenteils am Vorsprung des Kopfteils das Hül- senteil mit einer zuordenbaren Anlagefläche vollflächig an der Führungsbahn an, wobei die Anlageschulter des Hülsenteils das Ende des Ringbundes am oberen Ende der Führungsbahn übergreift. Die Anlagefläche des Hülsenteils bildet dadurch eine vollflächige Umfassung des Ringbundes des Kopfteils, so dass bei der über die Anlageschulter übertragenen Betätigungs- oder Abreißkraft ein Gegenlager gebildet ist, das ein radiales Ausweichen des Trennstellenbereichs des Kopfteils unter der Einwirkung der Betätigungskraft verhindert und dadurch einen besonderen sicheren Abreißvorgang gewährleistet. Für eine besonders sichere Übertragung der Trenn- oder Abreißkraft kann an der Innenumfangsseite des Ringbundes eine nach innen in Richtung des Trennbereichs vorspringende und sich an diesen anschließende Verstärkungsrippe vorhanden sein. Diese kann zumindest bei unbetätigtem Hülsenteil im Querschnitt gesehen eine Keilform ausbilden, deren längster Querschenkel in Richtung des Halsteils am Trennbereich endet und parallel beabstandet zu einer weiteren die Verstärkungsrippe abschließenden Grenzlinie angeordnet ist. In particularly advantageous embodiments, with an undercut of the bearing fingers of the sleeve part on the projection of the head part, the sleeve part with an assignable contact surface over the entire surface of the guideway, the abutment shoulder of the sleeve part engages over the end of the annular collar at the upper end of the guideway. The contact surface of the sleeve part thereby forms a full-surface enclosure of the annular collar of the head part, so that in the transmitted over the contact shoulder actuating or Abreißkraft an abutment is formed which prevents radial deflection of the separation region of the head portion under the action of the actuating force and thus a special safe Tear-off guaranteed. For a particularly secure transmission of the separating or tearing force may be present on the inner peripheral side of the annular collar inwardly projecting in the direction of the separation region and to this subsequent reinforcing rib. This can form a wedge shape seen in cross-section, at least when uninhibited sleeve part, the longest transverse leg ends in the direction of the neck portion at the separation area and parallel spaced apart from a further borderline terminating the reinforcing rib.
Für eine entsprechende Verstärkung am Öffnungsrand des Halsteils kann die Abgabeöffnung des Halsteils von einem Ringwulst begrenzt sein, der in Richtung des unbetätigten Hülsenteils über den Trennbereich vorspringend mit seinem größten Querschnittsmaß an den Trennbereich angrenzt.

Wie den Fig. 1 und 2 zu entnehmen ist, weist das vorliegende Ausführungsbeispiel des erfindungsgemäßen Behälters ein Behälterhauptteil 1 in Form einer Kunststoffflasche auf, die, bezogen auf eine zentrale Hauptachse 3, einen quadratischen Querschnitt mit abgerundeten Eckbereichen besitzt und für die Aufnahme einer Flüssigkeit mit einer Füllmenge von 150 ml ausgelegt ist. Wie am deutlichsten Fig. 2 zeigt, ist an der Oberseite des Hauptteils 1 ein zur Achse 3 koaxiales Halsteil 5 angeformt, dessen 1 and 2, the present embodiment of the container according to the invention a container main part 1 in the form of a plastic bottle, based on a central main axis 3, has a square cross-section with rounded corner areas and for receiving a liquid with a capacity of 150 ml is designed. As shown most clearly in Fig. 2, a coaxial to the axis 3 neck portion 5 is integrally formed on the upper side of the main part 1, whose
Durchmesser etwa der halben Breite des Hauptteils 1 entspricht und außenseitig auf etwa halber Länge mit einem Außengewinde 7 versehen ist. Wie am deutlichsten die Fig. 3 bis 5 zeigen, weist das Halsteil 5 in seinem oberen Bereich in geringem axialen Abstand vom obersten Gang des Außengewindes 7 eine Ringfläche 9 auf, die in Richtung der Achse 3 nach oben geneigt radial nach einwärts verläuft und am oberen Ende in eine nach oben und zur Achse 3 divergierend nach außen hin verlaufende Endfläche 1 1 übergeht, deren Endrand die Entnahmeöffnung 13 des Halsteils 5 umgibt. Dabei ist am Rand der Entnahmeöffnung 13 ein nach außen leicht vorspringender Randwulst 15 gebildet. Am Rand der Entnahmeöffnung 13 ist als Verschlussteil für die Entnahmeöffnung 13 ein Kopfteil 1 7 als einstü- ckiger Bestandteil des Halsteils 5 angeformt, wobei der Randwulst 15 zusammen mit einer Verstärkungsrippe 19, die sich am zugewandten Ende des Kopfteils 1 7 befindet, einen Trennbereich bildet, in dem die Verbindungsstelle zwischen Randwulst 15 und Verstärkungsrippe 19 eine Sollbruchstelle bildet, an der das Kopfteil 1 7 für einen Entnahmevorgang zur Freigabe der Entnahmeöffnung 13 vom Halsteil 5 ablösbar ist. Die Verstärkungsrippe 19 befindet sich als radial nach innen ragender, keilförmiger Vorsprung am Ende eines Ringbundes 21 , dessen Außenseite eine Zylindermantelfläche 23 bildet, an deren oberem Ende eine die radiale Länge der Zylindermantelfläche 23 begrenzende Stufenfläche 25 gebildet ist, die sich radial nach innen in eine sich anschließende Ringnut 27 des Kopfteils 17 erstreckt. Das obere Ende der Ringnut 27 ist durch einen radial nach außen ragenden, flanschartigen Vorsprung 29 begrenzt, der in die obere Endfläche 31 des Kopfteils 1 7 übergeht. Als Abreißhilfe zum Lösen des Kopfteils 1 7 an der am Trennbereich 15, 19 gebildeten Sollbruchstelle ist ein Hülsenteil 35, das in einem kreiszylindrischen Längenabschnitt ein Innengewinde 37 und außenseitig eine Längsrif- felung 39 besitzt, auf das Außengewinde 7 des Halsteils 5 aufschraubbar. An den die Riffelung 39 aufweisenden Umfangsabschnitt schließt sich eine Schrägfläche 41 an, die in Richtung der oberen freien Stirnseite den Außendurchmesser des Hülsenteils 35 verringert. Von der Schrägfläche 41 ausgehend erstreckt sich ein Kranz von Anlagefingern 43 zur oberen Stirnseite hin, wobei die Anlagefinger 43 zur Achse 3 hin geneigt sind. Im Bereich zwischen der Schrägfläche 41 und den Anlagefingern 43 bildet das Hül- senteil 35 innenseitig eine Anlageschulter 45 in Form einer in einer Radialebene liegenden Ringfläche. Die Fig. 3 zeigt das Hülsenteil 35 in einer nur teilweise aufgeschraubten Anfangsposition, bei der sich die Anlageschulter 45 in einem Abstand von der Stufenfläche 25 am Ringbund 21 befindet und sich die Anlagefinger 43 bis zur oberen Endfläche 31 des Kopfteils 17 erstrecken. Die Fig. 4 zeigt den Zustand, bei dem sich nach weiterem Aufschrauben das Hülsenteil 35 in einer Bereitschaftsposition befindet, bei der die Anlagefinger 43 unterhalb des Vorsprungs 29 in die Ringnut 27 des Kopfteils 1 7 eingeschnappt sind. Das Hülsenteil 35 hat sich hierbei so weit nach unten bewegt, dass eine kreiszylindrische, innere Anlagefläche 47, die sich im Bereich der Schrägfläche 41 am Hülsenteil 35 befindet, in vollflächiger Anlage an der äußeren Zylindermantelfläche 23 des Ringbundes 21 ist. Die Zylindermantelfläche 23 bildet dadurch für das Hülsenteil 35 eine Führungsbahn, an der das Hülsenteil 35 bei seiner Axialbewegung beim Aufschrauben geführt ist. Bei dem weiteren Aufschrauben aus der in Fig. 4 gezeigten Bereitschaftsposition zu der in Fig. 5 gezeigten Öffnungsposition, wobei die Anlagefläche 47 des Hülsenteils 35 an der durch die Zylindermantelfläche 23 des Ringbundes 21 gebildeten Führungswand gleitet, nimmt die Anlageschulter 45 des Hülsenteils 35, die die Stufenfläche 25 des Ringbundes 21 übergreift, das Kopfteil 17 mit, so dass die Sollbruchstelle am Trennbereich 15,1 7 reißt und die Entnahmeöffnung 1 3 frei ist, s. Fig. 5, wo dieser Zustand dargestellt ist. Diameter approximately equal to half the width of the main part 1 and the outside is provided at approximately half the length with an external thread 7. As most clearly shown in FIGS. 3 to 5 show, the neck portion 5 in its upper region at a small axial distance from the uppermost thread of the external thread 7 an annular surface 9 which extends in the direction of the axis 3 upwardly inclined radially inwardly and at the top End in an upward and to the axis 3 diverging outward extending end surface 1 1 passes, whose end edge surrounds the removal opening 13 of the neck portion 5. In this case, an outwardly slightly projecting edge bead 15 is formed at the edge of the removal opening 13. At the edge of the removal opening 13, a head part 1 7 is formed as a plug-in part of the neck part 5 as a closure part for the removal opening 13, wherein the edge bead 15 forms a separation area together with a reinforcing rib 19 which is located at the facing end of the head part 1 7 , in which the connection point between edge bead 15 and reinforcing rib 19 forms a predetermined breaking point, at which the head part 1 7 for a removal operation for releasing the removal opening 13 from the neck portion 5 is removable. The reinforcing rib 19 is located as a radially inwardly projecting, wedge-shaped projection at the end of a collar 21 whose outer side forms a cylindrical jacket surface 23, at the upper end of a radial length of the cylinder jacket surface 23 delimiting step surface 25 is formed, which extends radially inwardly into a subsequent annular groove 27 of the head part 17 extends. The upper end of the annular groove 27 is bounded by a radially outwardly projecting, flange-like projection 29, which merges into the upper end face 31 of the head part 1 7. As tear-off aid for releasing the head part 1 7 at the predetermined breaking point formed at the separating region 15, 19, a sleeve part 35, which has a female thread 37 in a circular-cylindrical longitudinal section and a longitudinal ribbing 39 on the outside, can be screwed onto the external thread 7 of the neck part 5. At the corrugation 39 having peripheral portion is followed by an inclined surface 41, which reduces the outer diameter of the sleeve part 35 in the direction of the upper free end face. Starting from the inclined surface 41, a ring of bearing fingers 43 extends to the upper end side, wherein the bearing fingers 43 are inclined to the axis 3 out. In the region between the inclined surface 41 and the bearing fingers 43, the sleeve part 35 forms on the inside a contact shoulder 45 in the form of a ring surface lying in a radial plane. FIG. 3 shows the sleeve part 35 in an initial screwed only initial position in which the abutment shoulder 45 is at a distance from the step surface 25 on the annular collar 21 and the bearing fingers 43 extend to the upper end surface 31 of the head portion 17. Fig. 4 shows the state in which after further screwing the sleeve member 35 is in a standby position, in which the bearing fingers 43 are snapped below the projection 29 in the annular groove 27 of the head part 1 7. The sleeve part 35 has in this case moved so far down that a circular cylindrical, inner bearing surface 47, which is located in the region of the inclined surface 41 on the sleeve part 35, in full contact with the outer cylindrical surface 23 of the annular collar 21. The cylinder jacket surface 23 thereby forms for the sleeve part 35 a guideway on which the sleeve part 35 is guided during its axial movement when screwing. In the further unscrewing from the standby position shown in Fig. 4 to the opening position shown in Fig. 5, wherein the abutment surface 47 of the sleeve member 35 slides on the formed by the cylinder jacket surface 23 of the annular collar 21 guide wall, the abutment shoulder 45 of the sleeve member 35, the the step surface 25 of the annular collar 21 overlaps, the head part 17, so that the predetermined breaking point at the separation region 15.1 7 breaks and the removal opening 1 3 is free, s. Fig. 5, where this state is shown.
Die Fig. 6 zeigt das Hülsenteil 35 in einer Position, bei der nach dem Öff- nungs- oder Abreißvorgang das Hülsenteil 35 aus der in Fig. 5 gezeigten Position teilweise abgeschraubt ist. Bei dieser Axialbewegung wird das Kopfteil 1 7 durch den Untergriff der Anlagefinger 43 am Vorsprung 29 mitgenommen, so dass bei vollständigem Abschrauben das Kopfteil 1 7 zusammen mit dem Hülsenteil 35 abgenommen ist und dabei das Kopfteil 1 7 unverlierbar am abgenommenen Hülsenteil 35 gesichert ist. Dadurch steht das Kopfteil 1 7 ohne Zutun des Bedieners zur Verfügung, wenn ein an- schließendes Wiederaufschrauben gewünscht sein sollte, um zusammen mit dem Hülsenteil 35 erneut aufgeschraubt zu werden. Dabei kann, da das Hülsenteil 35 mit seiner inneren Anlagefläche 47, die vollflächig an der die Führungsbahn bildenden Zylindermantelfläche 23 des Ringbundes 21 an- liegt, ein Widerlager für den Ringbund 21 bildet, ein Wiederverschluss der Entnahmeöffnung 13 durch Anziehen der Verschraubung und durch Anlage der Verstärkungsrippe 19 an der Ringfläche 9 des Halsteils 5 gebildet werden, s. Fig. 5. Bei einer ausreichend steifen Ausbildung der Anlagefinger 43 kann der Öffnungsvorgang auch durch Abschrauben des Hülsenteils 35 aus der Bereitschaftsposition (Fig. 4) heraus vorgenommen werden, wobei die Anlagefinger 43 bei der nach oben verlaufenden Axialbewegung das Kopfteil 17 im Untergriff mit dem Vorsprung 29 für eine nach oben verlaufende Abreiß- bewegung mitnehmen. FIG. 6 shows the sleeve part 35 in a position in which, after the opening or tearing process, the sleeve part 35 is partially unscrewed from the position shown in FIG. 5. In this axial movement, the head part 1 7 is taken by the lower grip of the bearing fingers 43 on the projection 29, so that upon complete unscrewing the head part 1 7 is removed together with the sleeve part 35 while the head part 1 7 captive on the removed sleeve part 35 is secured. As a result, the head part 1 7 is available without the intervention of the operator, if a closing re-screwing should be desired to be screwed together with the sleeve part 35 again. In this case, since the sleeve member 35 forms with its inner contact surface 47, the full surface of the guideway forming cylinder jacket surface 23 of the annular collar 21, an abutment for the annular collar 21, a reclosure of the removal opening 13 by tightening the screw and by conditioning the Reinforcing rib 19 are formed on the annular surface 9 of the neck portion 5, s. 5 with a sufficiently rigid design of the bearing fingers 43, the opening operation can also be carried out by unscrewing the sleeve part 35 from the standby position (FIG. 4), wherein the bearing fingers 43 in the upward axial movement, the head part 17 in the lower handle with the Take along projection 29 for an upward tear-off movement.
