Definitions
- the invention relates to a cartridge system for flowable masses with one or more, essentially hollow cylindrical containers and a pouring spout, which has separate pouring channels assigned to the containers, the pouring spout and container being designed as separate parts which can be displaced with respect to each other and the containers in Connection area of the pouring channels when moving the parts against one another have removable bottom parts which are arranged in the center of the container bottoms facing the pouring spout.
- the flowable masses arranged in this known cartridge system are used by means of a known squeezing device.
- the mouth area of the pouring spout is cut off, so that the pourable masses can be supplied to the mixer via the pouring channels that are open and are connected to the containers.
- a pressure piece serves this feed of the squeezing device, which acts on the respective pistons of the containers and thereby presses the flowable masses out of the containers via the pouring channels.
- a disadvantage of this known cartridge system is the cutting process on the pouring spout, which is not easy to carry out. If suitable tools are not available for this process, the spout may be damaged, which may affect the mixing ratios of the reaction components, so that incorrect use cannot be ruled out.
- the flowable masses are exposed after the cutting process and can thus lead to considerable contamination, both in the surrounding area and in connection with the extrusion device.
- the operator can come into contact with the masses, which further requires that gloves have to be worn because they are often highly reactive masses.
- a cartridge known from EP-A-0 039 245 has a disc-like base part which consists of a plastic-coated metal foil. Before this cartridge can be inserted into the corresponding dispenser, this bottom part must be removed. This is done with the help of a tubular pouring spout, which has teeth with barb-like recesses projecting at one end in the axial direction.
- the pouring spout is pushed into the outlet opening of the cartridge until the bottom part is separated from the connection point and comes to lie within the recesses of the pouring spout. After pulling out the pouring spout from the cartridge, the operator can remove the base part held in the recesses.
- the pouring spout Before the cartridge is inserted into the corresponding dispenser, the pouring spout must be inserted into the outlet opening of the cartridge.
- the invention has for its object to provide a cartridge system that ensures safe storage and safe transport of flowable masses as well as a simple clean opening of the cartridges by removing bottom parts.
- the object is achieved in that the bottom parts which can be removed by pressure are connected to the bottom of the container via an annular cross-sectional weakening acting as a predetermined separation point and ejectors for the removable bottom parts are arranged on the pouring spout, the cross section of the ejectors being substantially smaller than the cross section of the removable bottom parts and the ejectors are so long that the ejected bottom parts are brought into a distance from the connection area of the pouring channels, and the ejectors are supported on the removable bottom parts when the stops of the pouring nozzle and container are at a distance from one another.
- the container and pouring spout are designed as completely separate parts. This makes it possible to To completely seal the container from the outside, ie when using a hollow cylindrical container, the piston forms the closure on one end face and the container bottom on the other end face.
- the container base which is arranged opposite the piston, has a removable base part. This bottom part is only removed when the pouring spout has reached a certain position relative to the container, this position being advantageously characterized by a full stack of the container bottom and pouring spout.
- the pouring spout and container can appear as completely separate parts during storage and transport, or they can already be pre-assembled by hooks and eyes, it also being possible to hook several containers with one and the same pouring spout.
- the removable bottom parts are arranged in the center of the container bottoms facing the pouring spout, with an annular cross-sectional weakening in the container bottoms serving as the defined separation point for the defined separation of these bottom parts.
- ejectors are advantageously arranged on the pouring spout, which are still supported on the removable bottom parts when the stops of the pouring spout and container are arranged at a distance from one another.
- this distance is used up, ie when the stops, which are preferably designed as sealing surfaces, lie on one another, the ejectors protrude to a certain extent into the containers.
- This dimension is advantageously kept so large that a secure separation and pushing of the removable bottom parts into the containers is ensured, so that the pressure generated when the flowable masses are pressed out does not lead to a partial closing of the bottom parts by removing the bottom parts Container bottoms created openings can come.
- locking means are provided on the pouring spout and on the containers when the respective stops cooperate.
- a high degree of security against the emergence of flowable mass is given, in particular, if a pipe section is provided on the pouring spout which enters the openings formed in the container bottoms after the removable bottom parts have been separated.
- a pipe section is provided on the pouring spout which enters the openings formed in the container bottoms after the removable bottom parts have been separated.
- the cartridge system shown in FIGS. 1 and 2 consists of containers 1, 2 and a pouring spout 3 which can be displaced relative to these containers 1, 2.
- the containers 1, 2 are of essentially analog design except for their diameter.
- the different diameters come about, for example, from the application-related mixing ratio of the individual reaction components and are only to be understood as examples here.
- the pouring spout 3 has pouring channels 10, 11 assigned to each container 1, 2.
- the spout 3 ejector 12, 13.
- These ejectors 12, 13 are supported on the removable bottom parts 6, 7 when stops 14, 15 of the container 1, 2 and stops 16, 17 of the pouring spout 3 are arranged at a distance from one another, as shown in FIG. 1.
- the ejectors 12, 13 protrude into the containers 1, 2 while separating the removable bottom parts 6, 7, as shown in FIG. 2.
- FIG. 2 further shows how the separated, removable bottom parts can rest on the ejectors 12, 13, in order to prevent partial opening of the openings formed in the container bases 4, 5 after the removable bottom parts 6, 7 have been separated. Instead of this sitting, there is also the possibility of pushing the removable bottom parts 6, 7 fully into the containers 1, 2 by means of correspondingly long ejectors 12, 13.
- locking means are provided on the pouring spout 3 and on the containers 1, 2.
- These locking means are, for example, locking lugs 18, 19 which are arranged on fingers 20, 21, 22 of the container 1, 2.
- These locking lugs 18, 19 cooperate with a wall part 23 of the pouring spout 3, as shown in particular in FIG. 2. With this wall part 23 of the pouring spout 3, further locking lugs 24, 25 of the fingers 20, 21, 22 cooperate, so that the container 1, 2 and pouring spout 3 form a unit which is already preassembled during storage and transport.
- the pouring spout 3 is provided with pipe sections 26, 27.
- the diameter of these tube pieces 26, 27 corresponds to the diameter of the annular cross-sectional weakenings 8, 9, so that after the distance between the stops 14, 15, 16, 17 has been used up, a protrusion the container bottoms 4, 5 is given by the pipe sections 26, 27, as shown in FIG. 2.
- latching noses 28, 29 provided on the tube pieces 26, 27 come into effect, so that a latching is also ensured in these areas, specifically with the container bottoms 4, 5.
Abstract
Description
Die Erfindung betrifft ein Kartuschensystem für fliessfähige Massen mit einem oder mehreren, im wesentlichen hohlzylinderförmigen Behältern und einem Ausgussstutzen, der den Behältern zugeordnete, voneinander getrennte Ausgusskanäle aufweist, wobei Ausgussstutzen und Behälter als separate unter Zusammenwirken jeweiliger Anschläge gegeneinander verschiebbare Teile ausgebildet sind und die Behälter im Anschlussbereich der Ausgusskanäle beim Gegeneinanderverschieben der Teile entfernbare Bodenteile aufweisen, die im Zentrum der dem Ausgussstutzen zugewandten Behälterböden angeordnet sind.The invention relates to a cartridge system for flowable masses with one or more, essentially hollow cylindrical containers and a pouring spout, which has separate pouring channels assigned to the containers, the pouring spout and container being designed as separate parts which can be displaced with respect to each other and the containers in Connection area of the pouring channels when moving the parts against one another have removable bottom parts which are arranged in the center of the container bottoms facing the pouring spout.
Es ist weit verbreitet, fliessfähige Massen in Behältern zu lagern und zu transportieren. Bei solchen Behältern handelt es sich meistens um Hohlzylinder aus Kunststoff. Da die Massen jeweils bis unmittelbar vor ihrem Gebrauch reaktionsfähig sein müssen, ist dafür zu sorgen, dass während der Lagerung und dem Transport ein ausreichender Verschluss vorhanden ist und eine Oeffnung der Behälter erst unmittelbar vor dem Gebrauch der Massen erfolgt.It is widespread to store and transport flowable masses in containers. Such containers are mostly hollow cylinders made of plastic. Since the masses must be reactive until immediately before their use, it must be ensured that there is sufficient closure during storage and transport and that the containers are opened only immediately before the masses are used.
Beispielsweise bei der Verwendung von aushärtbaren Zweikomponenten-Massen ist es bekannt (Prospekt Hilti W1299/1984) ein Kartuschensystem mit zwei Behältern vorzusehen, wobei in jedem Behälter eine der Reaktionskomponenten angeordnet ist. Das Kartuschensystem weist einen Ausgussstutzen auf, der voneinander getrennte, mit den Behältern in Verbindung stehende Ausgusskanäle aufweist. Während der Lagerung und dem Transport dieses Kartuschensystems sind die Ausgusskanäle verschlossen. Auf der dem Ausgussstutzen entgegengesetzten Stirnseite der Behälter sind Kolben vorgesehen, welche die fliessfähige Masse abdichtend verschliessen.For example, when using curable two-component materials, it is known (prospect Hilti W1299 / 1984) to provide a cartridge system with two containers, one of the reaction components being arranged in each container. The cartridge system has a pouring spout which has pouring channels which are separate from one another and are connected to the containers. The pouring channels are closed during the storage and transport of this cartridge system. On the end of the container opposite the pouring spout, pistons are provided which seal the flowable mass.
Der Gebrauch der in diesem bekannten Kartuschensystem angeordneten fliessfähigen Massen erfolgt mittels eines bekannten Auspressgerätes.The flowable masses arranged in this known cartridge system are used by means of a known squeezing device.
Vor dem Einsetzen in ein solches Auspressgerät wird der Mündungsbereich des Ausgussstutzens abgeschnitten, so dass über die dadurch offenen, mit den Behältern in Verbindung stehenden Ausgusskanäle die fliessfähigen Massen dem Mischer zugeführt werden können. Dieser Zuführung dient ein Druckstück des Auspressgerätes, welches auf die jeweiligen Kolben der Behälter einwirkt und dadurch die fliessfähigen Massen über die Ausgusskanäle aus den Behältern herauspresst.Before being inserted into such a pressing device, the mouth area of the pouring spout is cut off, so that the pourable masses can be supplied to the mixer via the pouring channels that are open and are connected to the containers. A pressure piece serves this feed of the squeezing device, which acts on the respective pistons of the containers and thereby presses the flowable masses out of the containers via the pouring channels.
Nachteilig bei diesem bekannten Kartuschensystem ist der nicht einfach auszuführende Abschneidvorgang am Ausgussstutzen. Falls für diesen Vorgang nicht geeignete Werkzeuge zur Verfügung stehen, kann es zu Beschädigungen des Ausgussstutzens kommen, was sich auf die Mischverhältnisse der Reaktionskomponenten auswirken kann, so dass Fehlanwendungen nicht auszuschliessen sind.A disadvantage of this known cartridge system is the cutting process on the pouring spout, which is not easy to carry out. If suitable tools are not available for this process, the spout may be damaged, which may affect the mixing ratios of the reaction components, so that incorrect use cannot be ruled out.
Ueberdies liegen nach dem Abschneidvorgang die fliessfähigen Massen frei und können dadurch zu erheblichen Verschmutzungen, sowohl im Umgebungsbereich, als auch im Zusammenhang mit dem Auspressgerät führen. Ausserdem kann die Bedienungsperson mit den Massen in Kontakt kommen, was weiterhin erfordert, dass Handschuhe getragen werden müssen, weil es sich oftmals um hochreaktive Massen handelt.Moreover, the flowable masses are exposed after the cutting process and can thus lead to considerable contamination, both in the surrounding area and in connection with the extrusion device. In addition, the operator can come into contact with the masses, which further requires that gloves have to be worn because they are often highly reactive masses.
Eine aus der EP-A-0 039 245 bekannte Kartusche weist ein scheibenartiges Bodenteil auf, das aus einer kunststoffbeschichteten Metallfolie besteht. Bevor diese Kartusche in das entsprechende Auspressgerät eingesetzt werden kann, muss dieses Bodenteil entfernt werden. Dies geschieht mit Hilfe eines rohrförmigen Ausgussstutzens, der an einem Ende in axialer Richtung abstehende Zähne mit widerhakenartigen Ausnehmungen aufweist.A cartridge known from EP-A-0 039 245 has a disc-like base part which consists of a plastic-coated metal foil. Before this cartridge can be inserted into the corresponding dispenser, this bottom part must be removed. This is done with the help of a tubular pouring spout, which has teeth with barb-like recesses projecting at one end in the axial direction.
Zum Entfernen dieses Bodenteiles wird der Ausgussstzen so weit in die Auslassöffnung der Kartusche hineingeschoben, bis das Bodenteil von der Verbindungsstelle abgetrennt wird und innerhalb der Ausnehmungen des Ausgussstzens zu liegen kommt. Nach dem Herausziehen des Ausgussstutzens aus der Kartusche kann der Bediener das in den Ausnehmungen gehaltene Bodenteil entfernen.To remove this bottom part, the pouring spout is pushed into the outlet opening of the cartridge until the bottom part is separated from the connection point and comes to lie within the recesses of the pouring spout. After pulling out the pouring spout from the cartridge, the operator can remove the base part held in the recesses.
Bevor die Kartusche in das entsprechende Auspressgerät eingesetzt wird, muss der Ausgussstutzen wiederum in die Auslassöffnung der Kartusche gesteckt werden.Before the cartridge is inserted into the corresponding dispenser, the pouring spout must be inserted into the outlet opening of the cartridge.
Der Erfindung liegt die Aufgabe zugrunde, ein Kartuschensystem zu schaffen, das eine sichere Lagerung und einen sicheren Transport von fliessfähigen Massen sowie ein einfaches sauberes Oeffnen der Kartuschen durch Entfernung von Bodenteilen gewährleistet.The invention has for its object to provide a cartridge system that ensures safe storage and safe transport of flowable masses as well as a simple clean opening of the cartridges by removing bottom parts.
Erfingungsgemäss wird die Aufgabe dadurch gelöst, dass die durch Druck entfernbaren Bodenteile über eine ringförmige, als Solltrennstelle wirkende Querschnittsschwächung mit den Behälterböden verbunden sind und am Ausgussstutzen Ausstosser für die entfernbaren Bodenteile aungeordnet sind, wobei der Querschnitt der Ausstosser wesentlich kleiner als der Querschnitt der entfernbaren Bodenteile ist, und die Ausstosser so lange sind, dass die ausgestossenen Bodenteile in Abstand gegenüber der Anschlussbereich der Ausgusskanäle gebracht werden, und die Ausstosser sich an den entfernbaren Bodenteilen abstützen, wenn die Anschläge von Ausgussstutzen und Behälter im Abstand zueinander stehen.According to the invention, the object is achieved in that the bottom parts which can be removed by pressure are connected to the bottom of the container via an annular cross-sectional weakening acting as a predetermined separation point and ejectors for the removable bottom parts are arranged on the pouring spout, the cross section of the ejectors being substantially smaller than the cross section of the removable bottom parts and the ejectors are so long that the ejected bottom parts are brought into a distance from the connection area of the pouring channels, and the ejectors are supported on the removable bottom parts when the stops of the pouring nozzle and container are at a distance from one another.
Bei dem erfindungsgemäss vorgeschlagenen Kartuschensystem sind Behälter und Ausgussstutzen als vollkommen voneinander getrennte Teile ausgebildet. Dadurch ist es möglich, die Behälter vollumfänglich gegen aussen hin abzuschliessen, dh bei Verwendung eines hohlzylinderförmigen Behälters bildet auf der einen Stirnseite der Kolben und auf der anderen Stirnseite der Behälterboden den Verschluss. Der Behälterboden, der dem Kolben entgegengesetzt angeordnet ist, weist ein entfernbares Bodenteil auf. Dieses Bodenteil wird erst entfernt, wenn der Ausgussstutzen gegenüber dem Behälter eine bestimmte Lage erreicht hat, wobei diese Lage vorteilhaft durch ein sattes Aufeinanderliegen von Behälterboden und Ausgussstutzen gekennzeichnet ist.In the cartridge system proposed according to the invention, the container and pouring spout are designed as completely separate parts. This makes it possible to To completely seal the container from the outside, ie when using a hollow cylindrical container, the piston forms the closure on one end face and the container bottom on the other end face. The container base, which is arranged opposite the piston, has a removable base part. This bottom part is only removed when the pouring spout has reached a certain position relative to the container, this position being advantageously characterized by a full stack of the container bottom and pouring spout.
Ausgussstutzen und Behälter können bei der Lagerung und dem Transport als vollkommen voneinander getrennte Teile aufscheinen oder sie können durch Haken und Oesen bereits vormontiert sein, wobei es auch möglich ist, mehrere Behälter mit ein- und demselben Ausgussstutzen zu verhaken.The pouring spout and container can appear as completely separate parts during storage and transport, or they can already be pre-assembled by hooks and eyes, it also being possible to hook several containers with one and the same pouring spout.
Vor dem Gebrauch der in einem solchen Kartuschensystem gelagerten fliessfähigen Massen werden entweder die einzelnen Teile des Systems oder die gesamte vormontierte Einheit einem an sich bekannten Auspressgerät zugefürt. Bis und im Verlaufe dieser Zuführung bleiben die Behälter vollumfänglich verschlossen, so dass fliessfähige Masse weder austreten, noch mit der Bedienungsperson in Kontakt kommen kann. Beim Betätigen der Auspressvorrichtung, dh beim Einwirken der Druckstücke auf die Kolben der Behälter werden aufgrund des nicht entweichbaren Druckes die Behälter samt ihren Böden gegen den Ausgussstutzen getrieben, so dass der zwischen den Anschlägen von Ausgussstutzen und Behälter bestehende Abstand aufgebraucht wird und somit während dem Gegeneinanderverschieben von Behälterböden und Ausgussstutzen die dafür vorgesehenen Bodenteile entfernt werden.Before the flowable masses stored in such a cartridge system are used, either the individual parts of the system or the entire preassembled unit are fed to a pressing device known per se. Up to and in the course of this supply, the containers remain completely closed, so that flowable mass can neither escape nor come into contact with the operator. When the ejection device is actuated, i.e. when the pressure pieces act on the pistons of the containers, the containers and their bottoms are driven against the pouring spout due to the non-escaping pressure, so that the distance between the stops of the pouring spout and the container is used up and thus moved during the counter-movement the base parts intended for this purpose are removed from the container bottoms and pouring spouts.
Die entfernbaren Bodenteile sind im Zentrum der dem Ausgusstutzen zugewandten Behälterböden angeordnet, wobei dem definierten Abtrennen dieser Bodenteile eine ringförmige, als Solltrennstelle wirkende Querschnittsschwächung in den Behälterböden dient.The removable bottom parts are arranged in the center of the container bottoms facing the pouring spout, with an annular cross-sectional weakening in the container bottoms serving as the defined separation point for the defined separation of these bottom parts.
Der Sicherstellung des Abtrennens der entfernbaren Bodenteile von den Behälterböden dienen mit Vorteil am Ausgussstutzen angeordnet Ausstosser, die sich an den entfernbaren Bodenteilen noch abstützen, wenn die Anschläge von Ausgussstutzen und Behälter im Abstand zueinander angeordnet sind. Beim Aufbrauch dieses Abstandes, dh wenn die Anschläge, welche vorzugsweise als Dichtflächen ausgebildet sind, aufeinander liegen, ragen die Ausstosser um ein gewisses Mass in die Behälter hinein. Dieses Mass wird mit Vorteil so gross gehalten, dass ein sicheres Abtrennen und Hineinstossen der entfernbaren Bodenteile in die Behälter gewährleistet ist, so dass es durch den beim Auspressen der fliessfähigen Massen entstehenden Druck nicht wieder zu einem teilweisen Verschliessen der durch das Entfernen der Bodenteile in den Behälterböden geschaffenen Oeffnungen kommen kann.To ensure that the removable bottom parts are separated from the container bottoms, ejectors are advantageously arranged on the pouring spout, which are still supported on the removable bottom parts when the stops of the pouring spout and container are arranged at a distance from one another. When this distance is used up, ie when the stops, which are preferably designed as sealing surfaces, lie on one another, the ejectors protrude to a certain extent into the containers. This dimension is advantageously kept so large that a secure separation and pushing of the removable bottom parts into the containers is ensured, so that the pressure generated when the flowable masses are pressed out does not lead to a partial closing of the bottom parts by removing the bottom parts Container bottoms created openings can come.
Zur Sicherstellung, dass nach dem Abtrennen der Bodenteile zwischen den Anschlägen von Behälter und Ausgussstutzen nicht fliessfähige Masse heraustreten und beispielsweise das Auspressgerät verschmutzen kann, sind am Ausgussstutzen und an den Behältern bei Zusammenwirken der jeweiligen Anschläge miteinander in Verbindung tretende Rastmittel vorgesehen.To ensure that after the separation of the base parts between the stops of the container and the pouring spout, non-flowable mass can emerge and, for example, contaminate the extrusion device, locking means are provided on the pouring spout and on the containers when the respective stops cooperate.
Ein hohes Mass an Sicherheit gegen ein Heraustreten von fliessfähiger Masse ist insbesondere dann gegeben, wenn am Ausgussstutzen ein Rohrstück vorgesehen ist, das in die nach dem Abtrennen der entfernbaren Bodenteile in den Behälterböden entstandenen Oeffnungen eintritt. Um auch bei einer solchen Anordnung die Abdichtung ausreichend sicherzustellen, sind mit Vorteil diese Rohrstücke, deren Durchmesser etwa dem Durchmesser der ringförmigen Querschnittschwächungen entspricht, mit Rastmitteln versehen. Diese Rastmittel können sich beispielsweise mit dem restlichen Teil der Behälterböden verhaken.A high degree of security against the emergence of flowable mass is given, in particular, if a pipe section is provided on the pouring spout which enters the openings formed in the container bottoms after the removable bottom parts have been separated. In order to adequately ensure the seal even with such an arrangement advantageously provide these pipe pieces, the diameter of which corresponds approximately to the diameter of the annular cross-sectional weakenings, with locking means. These locking means can get caught, for example, with the remaining part of the container bottoms.
Die Erfindung soll nunmehr anhand einer sie beispielsweise wiedergebenden Zeichnung näher erläutert werden. Es zeigen:
- Fig. 1 ein Kartuschensystem mit Ausgussstutzen und zwei, verschlossene Bodenteile aufweisende Behälter,
- Fig. 2 das Kartuschensystem gemäss Fig. 1 mit geöffneten Bodenteilen der Behälter.
- 1 shows a cartridge system with pouring spout and two containers having closed base parts,
- Fig. 2 shows the cartridge system according to Fig. 1 with the bottom parts of the container open.
Das den Figuren 1 und 2 entnehmbare Kartuschensystem besteht aus Behältern 1, 2 sowie einem gegenüber diesen Behältern 1, 2 verschiebbaren Ausgussstutzen 3.The cartridge system shown in FIGS. 1 and 2 consists of containers 1, 2 and a
Die Behälter 1, 2 sind bis auf ihre Durchmesser im wesentlichen analog ausgebildet. Der unterschiedliche Durchmesser kommt beispielsweise durch das anwendungsbezogene Mischverhältnis der einzelnen Reaktionskomponenten zustande und soll hier nur beispielhaft verstanden werden.The containers 1, 2 are of essentially analog design except for their diameter. The different diameters come about, for example, from the application-related mixing ratio of the individual reaction components and are only to be understood as examples here.
Nach dem Füllen der Behälter 1, 2 werden diese an ihren offenen Stirnseiten mit bekannten, und daher zeichnerisch nicht dargestellten, Kolben verschlossen. Auf der gegenüberliegenden Seite sind Behälterböden 4, 5 vorhanden, welche im Zentrum entfernbare Bodenteile 6, 7 aufweisen. Diese entfernbaren Bodenteile 6, 7 werden von ringförmigen Querschnittsschwächungen 8, 9 umgeben.After the containers 1, 2 have been filled, they are closed on their open end faces by known pistons, which are therefore not shown in the drawing. On the opposite side there are
Der Ausgussstutzen 3 weist jedem Behälter 1, 2 zugeordnete Ausgusskanäle 10, 11 auf. Im gegenüberliegenden Bereich der entfernbaren Bodenteile 6, 7 der Behälter 1, 2 weist der Ausgussstutzen 3 Ausstosser 12, 13 auf. Diese Ausstosser 12, 13 stützen sich an den entfernbaren Bodenteilen 6, 7 ab, wenn Anschläge 14, 15 der Behälter 1, 2 und Anschläge 16, 17 des Ausgussstutzens 3 im Abstand voneinander angeordnet sind, wie dies Fig. 1 zeigt. Beim Aufbrauch des Abstandes dieser Anschläge 14, 15, 16, 17 ragen die Ausstosser 12, 13 unter Abtrennung der entfernbaren Bodenteile 6, 7 in die Behälter 1, 2 hinein, wie dies Fig. 2 zeigt.The
Fig. 2 zeigt weiterhin, wie die abgetrennten entfernbaren Bodenteile auf den Ausstossern 12, 13 aufsitzen können, um so ein teilweises Verschliessen der, nach dem Abtrennen der entfernbaren Bodenteile 6, 7 in den Behälterböden 4, 5 entstandenen Oeffnungen zu verhindern. Anstelle dieses Aufsitzens besteht auch die Möglichkeit durch entsprechend lange Ausstosser 12, 13 die entfernbaren Bodenteile 6, 7 vollumfänglich in die Behälter 1, 2 hineinzustossen.FIG. 2 further shows how the separated, removable bottom parts can rest on the
Wie wiederum die Fig. 1 und 2 zeigen, sind am Ausgussstutzen 3 und an den Behältern 1, 2 in Verbindung tretende Rastmittel vorgesehen. Bei diesen Rastmitteln handelt es sich beispielhaft um Rastnasen 18, 19, welche an Fingern 20, 21, 22 der Behälter 1, 2 angeordnet sind. Diese Rastnasen 18, 19 wirken mit einem Wandungsteil 23 des Ausgussstutzens 3 zusammen, wie dies insbesondere Fig. 2 zeigt. Mit diesem Wandungsteil 23 des Ausgussstutzens 3 wirken weitere Rastnasen 24, 25 der Finger 20, 21, 22 zusammen, so dass Behälter 1, 2 und Ausgussstutzen 3 eine schon während der Lagerung und dem Transport vormontierte Einheit bilden.As again shown in FIGS. 1 and 2, locking means are provided on the
Wie die Fig. 1 und 2 ferner zeigen, ist der Ausgussstutzen 3 mit Rohrstücken 26, 27 versehen. Der Durchmesser dieser Rohrstücke 26, 27 entspricht dem Durchmesser der ringförmigen Querschnittsschwächungen 8, 9, so dass nach Aufbrauch des Abstandes zwischen den Anschlägen 14, 15, 16, 17 ein Durchragen der Behälterböden 4, 5 durch die Rohrstücke 26, 27 gegeben ist, wie dies Fig. 2 zeigt. In dieser Stellung kommen an den Rohrstücken 26, 27 vorgesehene Rastnasen 28, 29 zur Wirkung, so dass auch in diesen Bereichen eine Verrastung, und zwar mit den Behälterböden 4, 5 sichergestellt ist.1 and 2 also show, the
