Abstract

A barrel of thermoplastic material has a peripherally extending carrier and transportation ring in the region of its upper end portion and at least one plughole connection in the edge region of the latter. The bung hole connection is disposed within a housing which is let into the upper end portion. The housing is open at its side towards the edge of the barrel while at its other side it has a boundary end wall, from each of the two ends of which a respective wall extends towards the edge of the barrel, the walls laterally defining the housing. The walls defining the housing are delimited at the top side by a transition from the respective wall into the upper end portion of the barrel and at the lower end by a transition from the respective wall into the bottom of the housing. The spacing between the upper transitions of the two ends of the housing is greater than the spacing between the two lower transitions and the upper transitions diverge towards the edge of the barrel. The transitions between the side walls and the upper end portion of the barrel body on the one hand and the transitions between the side walls and the bottom of the housing on the other hand do not extend parallel. The transitions between the side walls and the upper end portion include an angle which is at least 120 DEG .

Description

Die Erfindung betrifft ein Spundfaß aus thermoplastischem Kunststoff gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a bung from thermoplastic Plastic according to the preamble of claim 1.

Bei einem aus EP 0 291 695 A2 bekannten derartigen Spundfaß ist die Anordnung so getroffen, daß der Spundlochstutzen zumindest teilweise in das Innere des Fasses hineinragt und an seinem Abschnitt, der sich im Inneren des Fasses befindet, mit wenigstens einer Durchbrechung versehen ist, um eine weitgehende Entleerung des Fasses zu ermöglichen. Diese Ausgestaltung hat den Nachteil, daß der Spundlochstutzen gesondert hergestellt und in einem besonderen Arbeitsgang am Fasskörper angebracht werden muß. Es können somit die Vorteile des Blasverfahrens, das vielfach für die Fertigung derartiger Kunststoff-Fässer benutzt wird und eine einstückige Herstellung in einem Arbeitsgang ermöglicht, nicht genutzt werden.In a bung barrel of this type known from EP 0 291 695 A2 the arrangement is made so that the bunghole at least partially protrudes into the interior of the barrel and on its section, which is inside the barrel, with at least one opening is provided to a large extent To allow emptying of the barrel. This configuration has the disadvantage that the bunghole connector is separate manufactured and in a special operation on the barrel body must be attached. The advantages of the blowing process, often for the production of such plastic drums is used and a one-piece production in allows one operation to be used.

Der Erfindung liegt die Aufgabe zugrunde, ein Spundfaß aus thermoplastischem Kunststoff so herzustellen, das bezüglich der Restentleerung noch bessere Eigenschaften aufweist als das Faß gemäß EP 0 291 695 A2 und dabei auf einfache Weise herstellbar ist.The invention has for its object a bung from to manufacture thermoplastic so that the residual emptying has even better properties than that Barrel according to EP 0 291 695 A2 and thereby easy to manufacture is.

Diese Aufgabe wird gelöst durch die Anwendung der im Kennzeichen des Anspruches 1 angegebenen Merkmale.This problem is solved by using the in the license plate of claim 1 specified features.

Die Erfindung läßt sich dahingehend zusammenfassen, daß die beiden Übergänge, die jede Seitenwand des Gehäuses jeweils oben und unten begrenzen, von der stirnseitigen Begrenzungswand desselben in Richtung auf den Randbereich des Fasses divergieren mit der Folge, daß die Neigung jeder Seitenwand von der Stirnwand in Richtung auf den Randbereich abnimmt.The invention can be summarized in that the two transitions each side wall of the case delimit above and below from the front boundary wall the same in the direction of the edge region of the barrel diverge with the result that the slope of each side wall decreases from the front wall towards the edge area.

Zwar ist aus EP 0 515 390 B1 ein Spundfaß bekannt, bei welchem der Oberboden zusätzlich zum bzw. neben dem Spundlochstutzen-Gehäuse ein im wesentlichen kreisabschnittsförmiges Flächenteil bzw. eine Abschrägung aufweist, wobei die Abschrägung ihre tiefste Stelle auf der Seite des Faßmantels im Nahbereich des Spundlochstutzens hat. Diese Ausgestaltung hat jedoch zur Folge, daß im Bereich des Oberbodens verhältnismäßig viele gebogene und abgewinkelte Wandbereiche vorhanden sind, die zum Teil etwa rechtwinklig zueinander verlaufen und eine Versteifung des Oberbodens bewirken, die bei Beanspruchungen des Oberbodens durch Stoß und Schlag zu unkontrollierbaren Spannungen und unzulässigen Beanspruchungen des Kunststoffmaterials führen kann. Die Anwendung der Erfindung führt zu einer einfacheren Ausgestaltung, da der Oberboden neben dem Spundlochgehäuse keine weiteren Abschrägungen und kreisabschnittförmige Flächen benötigt, um den angestrebten Effekt zu erzielen.A bung is known from EP 0 515 390 B1, in which the top floor in addition to or next to the bunghole housing an essentially circular segment-shaped surface part or has a bevel, the bevel its lowest point on the side of the barrel jacket in the close range of the bunghole. However, this configuration has Consequence that a relatively large number in the area of the top floor curved and angled wall areas are available to the Part run approximately at right angles to each other and a stiffening of the topsoil, which when the Upper floor through shock and impact to uncontrollable tensions and impermissible stresses on the plastic material can lead. The application of the invention leads to a simpler design because the top floor next to the bunghole housing no further bevels and circular sections Areas needed to achieve the desired effect.

Tatsächlich sind es die seitlichen Begrenzungswände des Spundlochstutzen-Gehäuses, die aufgrund ihres erfindungsgemäßen Verlaufes in der Entleerungsposition des Fasses zugleich auch eine weitestgehende Restentleerung ermöglichen. Allgemein wird gelten, daß mit zunehmendem Winkel, welcher von den beiden seitlichen Wandungen des Spundlochstutzen-Gehäuses gebildet wird, eine zunehmende Restentleerung erreicht wird. Da andererseits mit zunehmendem Winkel die verbleibende Fläche des Oberbodens, die als Stapelfläche benutzt wird, abnimmt, wird es in der Praxis darauf ankommen, ein Optimum bezüglich beider Erfordernisse zu finden. Dies ist ohne weiteres möglich, da beispielsweise bei einem Winkel von 140°, der von den beiden Seitenwänden an ihrem Übergang zum Oberboden eingeschlossen wird, im allgemeinen einen allen praktischen Erfordernissen genügende Restentleerung erreichbar und die Stapelfläche ausreichend groß ist.In fact, it is the side boundary walls of the Bunghole connector housing, due to their invention Course in the emptying position of the barrel at the same time also enable the greatest possible residual emptying. Generally will apply that with increasing angle, which of the two lateral walls of the bunghole housing formed increasing residual emptying is achieved. There on the other hand, with increasing angle, the remaining area of the top floor, which is used as a stacking surface, in practice it will be important to find the optimum to find both requirements. This is easily possible because, for example, at an angle of 140 ° from the included both side walls at their transition to the top floor will generally meet all practical requirements sufficient residual emptying and the stacking area is sufficiently large.

Ein weiterer Vorteil des Fasses gemäß der Erfindung besteht darin, daß, da die Seitenwände des Gehäuses flacher verlaufen als beim Stand der Technik, die Formgebung des Fasses im Blasverfahren einfacher ist. Dies ist insbesondere deshalb von Bedeutung, weil normalerweise die Trennfläche der im allgemeinen zweiteiligen Blasform durch den Stutzen und damit durch das Stutzengehäuse verläuft mit der Folge, daß der Vorformling, aus welchem das Faß durch Anwendung von innerem Überdruck hergestellt wird, zwischen den beiden Formteilen gerade nahe dem Bereich entlang der Trennfläche eingespannt ist, in welchem der Vorformling zur Bildung von stark abgewinkelten und gebogenen Wandbereichen z. B. im Bereich des Gehäuses verformt werden muß. Das Faß gemäß der Erfindung verringert auf Grund der Ausgestaltung des Gehäuses die sich daraus ergebenden Probleme. Auch ist das Entformen des Fasses gemäß der Erfindung auf Grund seiner Ausgestaltung des Gehäusebereiches merklich einfacher.Another advantage of the barrel according to the invention is in that since the side walls of the housing are flatter than in the prior art, the shape of the barrel in Blowing process is easier. This is particularly why Meaning because normally the interface of the in general two-part blow mold through the nozzle and thus through the nozzle housing runs with the result that the preform, from which the barrel by applying internal pressure is made between the two moldings straight is clamped near the area along the parting surface, in which the preform to form strongly angled and curved wall areas such. B. in the area of the housing must be deformed. The barrel reduced according to the invention due to the design of the housing, the resulting Problems. Also the demolding of the barrel is according to the Invention due to its design of the housing area noticeably easier.

Die Übergänge zwischen den Seitenwänden des Gehäuses und dessen Bodens können im wesentlichen parallel zueinander verlaufen. Es kann aber auch zweckmäßig sein, diese Übergänge von der stirnseitigen Begrenzungswand des Gehäuses in Richtung auf den Faßrand etwas konvergieren zu lassen, mit dem Ergebnis, daß der Gehäuseboden in Richtung auf den Faßrand etwas schmaler wird und damit auch die beiden Übergänge noch näher am Spundloch liegen, wodurch die Restentleerung zusätzlich verbessert wird.The transitions between the side walls of the housing and its Soil can run essentially parallel to each other. But it can also be useful to make these transitions from the front boundary wall of the housing in the direction to let something converge on the rim of the barrel, with the result that the bottom of the case towards the barrel edge somewhat becomes narrower and thus the two transitions even closer lie on the bung hole, which means that the residual emptying additionally is improved.

Das in der Zeichnung dargestellte Ausführungsbeispiel eines stapelbaren Spundfasses 10 weist einen Faßkörper 12, einen Oberboden 14 und einen Unterboden 16 auf. Der Oberboden 14 ist mit zwei muldenförmigen Vertiefungen versehen, die jeweils ein Gehäuse 18 bzw. 20 für einen Stutzen 22 bzw. 24 bilden. Jeder Stutzen begrenzt eine Öffnung 25 bzw. 26. Das Faß 10 ist im Bereich des Oberbodens 14 mit einem umlaufenden Transportring 28 versehen, der von einem umlaufenden Steg 58 getragen ist. Letzterer begrenzt mit dem Oberboden 14 eine noch oben offene Nut 30.The embodiment shown in the drawing Stackable bung barrel 10 has a barrel body 12, a Upper floor 14 and a lower floor 16. The top shelf 14 is provided with two trough-shaped depressions, each one Form housing 18 or 20 for a nozzle 22 or 24. Everyone Neck limits an opening 25 and 26. The barrel 10 is in the Area of the top floor 14 with a circumferential transport ring 28 provided, which is supported by a circumferential web 58. The latter delimits an open top with the top floor 14 Slot 30.

Üblicherweise dient nur eine der beiden Öffnungen des Fasses der Restentleerung, während die andere Öffnung für die normale Entleerung des Fasses beispielsweise unter Verwendung eines eine Pumpe eingeschlossenen Rohres benutzt wird, welches durch die Öffnung in das Faßinnere eingeführt wird. Das dem Stutzen dieser Öffnung zugeordnete Gehäuse kann deshalb auch in üblicher Weise, also enger ausgeführt sein, um eine möglichst große Stapelfläche zu erhalten. Das Faß gemäß der Zeichnung ist mit zwei Öffnungen für die Restentleerung versehen und zeigt mögliche unterschiedliche Ausgestaltungen des Gehäuses.Usually only one of the two openings of the barrel serves the remaining drain while the other opening for normal Emptying the barrel using, for example a pump enclosed pipe is used, which is inserted through the opening into the interior of the barrel. That the This housing can also be assigned to this opening be carried out in the usual way, that is to say as close as possible to get large stacking area. The barrel according to the Drawing is provided with two openings for residual emptying and shows possible different configurations of the Housing.

Die Tiefe beider Gehäuse 18, 20 ist so bemessen, daß der jeweilige Stutzen 22 bzw. 24 nicht nach oben über die obere Begrenzungsfläche 29 des Oberbodens, die zugleich als Stapelfläche dient, hinausragt.The depth of both housings 18, 20 is such that the respective Spigot 22 or 24 not up over the top Boundary surface 29 of the top floor, which is also a stacking surface serves, protrudes.

Jedes der beiden im Randbereich des Oberbodens 14 angeordneten Gehäuse 18, 20 ist an seiner dem Faßrand bzw. dem Ring 28 zugekehrten Seite offen. An der gegenüberliegenden, dem Ring 28 jeweils abgekehrten Seite des Stutzens 22 bzw. 24 ist das Gehäuse durch eine Stirnwand 32 bzw. 34 begrenzt, die geneigt zwischen dem Boden 36 bzw. 38 des Gehäuses und dem Oberboden 14 verläuft. In der Zeichnung, insbesondere in Fig. 2, sind die Übergänge 48, 50 zwischen der jeweiligen Stirnwand 32 bzw. 34 einerseits und dem Gehäuseboden bzw. dem Oberboden 14 andererseits als Kanten dargestellt. Tatsächlich handelt es sich dabei jedoch um abgerundete Übergänge, wie dies bei der Formgebung von Kunststoffen, insbesondere im Blasverfahren durchweg üblich ist. Each of the two arranged in the edge region of the top floor 14 Housing 18, 20 is at its barrel edge or ring 28 facing side open. On the opposite, the ring 28 each facing side of the nozzle 22 or 24 is that Housing bounded by an end wall 32 and 34, respectively, which is inclined between the bottom 36 or 38 of the housing and the top floor 14 runs. In the drawing, in particular in Fig. 2, are the transitions 48, 50 between the respective end wall 32 or 34 on the one hand and the housing base or the upper base 14 on the other hand shown as edges. It actually does However, these are rounded transitions, as is the case with Shaping of plastics, especially in the blow molding process is common throughout.

An beiden Enden der stirnseitigen Begrenzungswand 32 bzw. 34 schließt sich jeweils eine seitliche Begrenzungswand 40 bzw. 42 an, die sich auch zwischen dem Gehäuseboden 36 bzw. 38 einerseits und dem Oberboden 14 erstreckt. Auch hier sind abgerundete Übergänge 44 zwischen Gehäuseboden 36 bzw. 38 und der jeweiligen Wandung 40 bzw. 42 sowie zwischen der jeweiligen Wandung und dem Oberboden 14 vorgesehen, wobei die letztgenannten Übergänge mit 46 bezeichnet sind. Im Unterschied zu den die stirnseitigen Wandungen 32 bzw. 34 begrenzenden Übergängen 48, 50, die im wesentlichen parallel verlaufen, sind die Übergänge 44 und 46 divergierend angeordnet derart, daß, ausgehend von der jeweils zugehörigen Stirnwand 32 bzw. 34 der Abstand zwischen den Übergängen 44, 46 in Richtung auf den L-Ring und damit den Faßrand zunimmt. Insbesondere Fig. 2 läßt erkennen, daß die die Seitenwandungen unten und oben begrenzenden Übergänge 44, 46 sehr stark divergieren, so daß die Seitenwandungen Schrägflächen bilden, deren Neigung von der jeweils zugehörigen Stirnwand 32 bzw. 34 in Richtung auf den Transportring 28 abnimmt. Es entstehen somit in Richtung auf den Rand und die jeweilige Öffnung 26 bzw. 28 verlaufende Schrägflächen, die, wie insbesondere Fig. 5 erkennen läßt, in der Entleerungsstellung des Fasses gemäß den Fig. 3 und 4 die Flüssigkeit in Richtung auf die jeweilige Öffnung 26 bzw. 28 leiten.At both ends of the end boundary wall 32 and 34 closes a lateral boundary wall 40 or 42, which is also between the housing base 36 and 38 on the one hand and the top floor 14 extends. Are here too rounded transitions 44 between the housing base 36 and 38 and of the respective wall 40 or 42 and between the respective Wall and the top floor 14 provided, the latter Transitions are designated by 46. In contrast to the transitions delimiting the end walls 32 and 34, respectively 48, 50 which are substantially parallel the transitions 44 and 46 are arranged in a divergent manner such that starting from the respectively associated end wall 32 or 34 of the Distance between the transitions 44, 46 towards the L-ring and thus the barrel edge increases. 2 in particular recognize that the side walls delimit below and above Transitions 44, 46 diverge very strongly, so that the Sidewalls form inclined surfaces, the inclination of which each associated end wall 32 and 34 in the direction of the Transport ring 28 decreases. It thus arises in the direction of the edge and the respective opening 26 and 28 extending Inclined surfaces which, as can be seen in particular in FIG. 5, in the emptying position of the barrel according to FIGS. 3 and 4 Liquid in the direction of the respective opening 26 or 28 conduct.

Die beiden Übergänge 44 zwischen den Seitenwänden 40, 42 jedes Gehäuses 18, 20 und dem Gehäuseboden 36 bzw. 38 verlaufen dabei dicht neben dem Stutzen 22 bzw. 24, so daß, wenn die oberen Übergänge 46 einen Winkel α von beispielsweise 140° einschließen, jede Seitenwand 40, 42 eine Erstreckung von etwa 70° im Bogenmaß zwischen unterem Übergang 44 und oberem Übergang 46 aufweist. Das jeweilige Bogenmaß entspricht somit der Länge des Überganges 70 zwischen der Seitenwand 40 bzw. 42 einerseits und der Begrenzung der Nut 30 andererseits. Da die Länge des Überganges 70 auch in bezug auf die Entleerung in einer bestimmten Position des Fasses das Gefälle bestimmt, kann letzteres demzufolge auch über die Wahl der Größe des Winkels α bestimmt werden. Ein Winkel α von mehr als 180° wird normalerweise nicht in Betracht kommen, wenn das Faß stapelbar sein soll, da dann die Stapelfläche zu stark reduziert werden würde und die Gefahr bestünde, daß der Stutzen eine tragende Funktion übernehmen müßte.The two transitions 44 between the side walls 40, 42 each Housing 18, 20 and the housing base 36 and 38 extend close to the nozzle 22 or 24, so that when the upper transitions 46 an angle α of, for example, 140 ° include, each side wall 40, 42 an extension of about 70 ° in radians between the lower transition 44 and the upper transition 46 has. The respective radians therefore correspond to Length of the transition 70 between the side wall 40 and 42 on the one hand and the limitation of the groove 30 on the other. Since the Length of the transition 70 also in relation to the emptying in a certain position of the barrel determines the slope, the latter can therefore also about the choice of the size of the Angle α can be determined. An angle α of more than 180 ° is not normally considered if the keg is stackable should be, since then the stacking area will be reduced too much and there would be a risk that the nozzle would be a load-bearing one Function would have to take over.

Bei dem in Fig. 2 rechts dargestellten Gehäuse 20 verlaufen die beiden Übergänge 44 von der stirnseitigen Begrenzungswand 34 ausgehend im wesentlichen parallel zum Faßrand, an welchem das nur an drei Seiten durch die Wandungen begrenzte Gehäuse offen ist. Letzteres gilt auch für das links in Fig. 2 dargestellte Gehäuse 18, dessen unteren Übergänge 44 der Seitenwandungen jedoch, ausgehend von der zugehörigen Stirnwand 32, in Richtung auf den Faßrand etwas konvergieren, wodurch das fließfähige Füllgut durch die schrägen seitlichen Wände 42, 44 noch dichter an die Auslauföffnung 26 herangeführt wird.The housing 20 shown on the right in FIG. 2 runs the two transitions 44 from the end wall 34 starting essentially parallel to the barrel edge, on which the housing limited only on three sides by the walls is open. The latter also applies to the one shown on the left in FIG. 2 Housing 18, the lower transitions 44 of the side walls however, starting from the associated end wall 32, converge somewhat towards the edge of the barrel, causing the flowable filling material through the oblique side walls 42, 44 is brought closer to the outlet opening 26.

Insbesondere Fig. 3 läßt erkennen, daß der Boden 36 des Gehäuses 18 im Bereich zwischen Stutzen 22 und dem Faßrand mit einer Falte 52 versehen ist, die einen nach oben aus dem Gehäuseboden 36 vorstehenden Wulst 54 bildet, dem eine Vertiefung 56 an der Innenseite des Gehäusebodens 36 entspricht. Diese Falte bildet eine Verformungszone zwischen Faßrand bzw. dem den Transportring 28 tragenden ringförmigen Steg 58 einerseits und dem jeweiligen Stutzen 22 bzw. 24 andererseits, die dazu dient, auf den Faßrand in Richtung auf den Stutzen einwirkende Kräfte zumindest soweit abzufangen, daß keine unzulässigen Beanspruchungen im Bereich des Stutzens auftreten. Zwar wird dieser Effekt durch eine zeitweilige Verformung der Falte erreicht. Dies ist jedoch ohne Bedeutung, da die Falte nach Beendigung der Stoß- oder Schlagbeanspruchung wieder in die ursprüngliche Lage zurückfedert.In particular Fig. 3 reveals that the bottom 36 of the housing 18 in the area between nozzle 22 and the barrel edge with a fold 52 is provided which one up from the housing bottom 36 protruding bead 54 forms a recess 56 on the inside of the housing base 36 corresponds. This fold forms a deformation zone between the barrel edge or the annular web 58 carrying the transport ring 28 on the one hand and the respective nozzle 22 and 24 on the other hand, the serves to act on the barrel edge towards the nozzle Intercept forces at least to the extent that no inadmissible Strains occur in the area of the nozzle. This effect is caused by a temporary deformation of the Crease reached. However, this is irrelevant since the fold after the impact or impact stress is back in the original situation springs back.

Weiterhin ist das Faß 10 an seiner Innenseite mit einer im wesentlichen radial verlaufenden rillenförmigen Vertiefung 60 (Fig. 3 und 5) versehen, die sich von der durch die Falte 52 bewirkten Vertiefung 56 etwa radial durch den in der Normalposition des Fasses unteren Bereich des Stutzens 22 bzw. 24 in die von diesem begrenzte Öffnung 25 bzw. 26 erstreckt. Dazu ist der Stutzen an seinem in der Normalposition unteren Randbereich mit einer Ausnehmung 62 versehen. Die Rinne 60 soll eine noch weitergehende Entleerung des Fasses ermöglichen, damit auch im Bereich zwischen Stutzen und Faßrand befindliche Füllgutreste, ggf. durch entsprechendes Verschwenken des Fasses, aus dem Faß ausfließen können.Furthermore, the barrel 10 is on the inside with a essentially radial groove-shaped depression 60 (Fig. 3 and 5) provided, which is different from the fold 52 caused depression 56 approximately radially through the in the normal position of the barrel lower area of the nozzle 22 or 24 in the opening 25 and 26 bounded by this extends. To is the nozzle at its bottom in the normal position Edge area provided with a recess 62. The gutter 60 should enable the barrel to be emptied even further, thus also in the area between the nozzle and the barrel edge Product residues, if necessary by swiveling accordingly of the barrel from which the barrel can flow.

In Fig. 3 der Zeichnung ist dargestellt, daß während der Entleerung des restlichen Füllgutes letzteres etwa vom Bereich A über die seitlichen vorzugsweise ebenen Begrenzungswänden 40, 42 in Richtung der Pfeile 64 in den Bereich B zwischen Stutzen und Faßrand fließt und von dort insbesondere durch die rinnenförmige Vertiefung 60 in den Stutzen und durch diesen aus dem Faß herausläuft.In Fig. 3 of the drawing it is shown that during the emptying of the rest of the filling, the latter approximately from area A over the lateral, preferably flat, boundary walls 40, 42 in the direction of arrows 64 in area B between the nozzles and barrel edge flows and from there in particular through the channel-shaped Well 60 in the nozzle and through this from the Barrel runs out.

Durch die vorbeschriebene Ausgestaltung wird erreicht, daß die Seitenwandungen des Gehäuses zusätzlich die Funktion übernehmen, bei der Entleerung das Füllgut in Richtung auf die Entleerungsöffnung zu leiten.The configuration described above ensures that the Side walls of the housing also take on the function when emptying the filling material in the direction of the emptying opening to lead.
