Description

Die Erfindung betrifft eine Dose für aromatische Stoffe.The invention relates to a can for aromatic substances.

Dosen dieser Art dienen zum Aufbewahren von stark aromahaltigen Stoffen, wie Kaffee, Tee, Tabak oder Gewürzen. Bei den herkömmlichen Gebrauchsdosen wird der über den eingefüllten Stoffen bestehende Luftraum bei der allmählichen Leerung immer größer. Dies hat zur Folge, daß die im Luftraum über diesem Füllgut durch Temperaturunterschiede zwischen dem Innenraum und der äußeren Umgebung hervorgerufene Luftzirkulation erheblich zunimmt und damit das Aroma beträchtlich leidet.Cans of this type are used to store substances with a strong aroma, such as coffee, tea, tobacco or spices. With conventional storage boxes, the air space above the filled substances increases with the gradual emptying. The result of this is that the air circulation caused by temperature differences between the interior and the outside environment in the air space above this filling material increases considerably and the aroma therefore suffers considerably.

Zur Abhilfe dieses Problems sind Dosen geschaffen worden, die das über dem Füllgut befindliche Luftvolumen so klein wie möglich halten. In der US-A- 2 726 012 wird dies durch einen Deckel erreicht, der auf dem Füllgut aufliegt und gegen die innere Seitenwand der Dose dicht schließt. Der Deckel wird entweder von Hand auf das Füllgut gedrückt oder er sinkt aufgrund seiner Schwerkraft nach unten.To remedy this problem, cans have been created which keep the air volume above the contents as small as possible. In US-A-2 726 012 this is achieved by a lid which rests on the filling material and closes tightly against the inner side wall of the can. The lid is either pressed onto the product by hand or it sinks down due to its gravity.

In der EP-A- 0 135 974 ist eine Dose beschrieben, bei der ein Stempel, der am Deckel angebracht ist, von oben auf das Füllgut gedrückt wird. Das DE-GM 72 32 726 zeigt eine Dose, bei der ebenfalls ein Deckel auf dem Füllgut aufliegt. Das Füllgut wird im Bereich des Dosenbodens entnommen. Der Deckel gleitet bei der Füllgutentnahme weiter nach unten.EP-A-0 135 974 describes a can in which a stamp, which is attached to the lid, is pressed onto the filling material from above. DE-GM 72 32 726 shows a can, in which a lid also rests on the contents. The Contents are removed from the area of the can base. The lid slides further down when the product is removed.

Die vorliegende Erfindung hat die Aufgabe, eine Dose für aromatisierte Stoffe zu schaffen, bei der unabhängig von der jeweiligen Höhe des Füllstandes das Aroma auch auf der obersten Schicht des- Einfüllgutes völlig erhalten bleibt, bei der das Füllgut bequem und leicht in herkömmlicher Weise entnehmbar ist und die kostengünstig herzustellen ist.The present invention has for its object to provide a can for flavored substances in which, regardless of the level of the fill level, the aroma is completely preserved even on the top layer of the filling material, in which the filling material can be removed conveniently and easily in a conventional manner and which is inexpensive to manufacture.

Diese Aufgabe wird erfindungsgemäß durch eine Dose für aromatische Stoffe mit einer höhenverschiebbaren Einrichtung zur Minimierung des oberhalb des Füllgutes befindlichen Luftvolumens gelöst, bei der die Einrichtung ein das Füllgut tragender Boden ist.This object is achieved according to the invention by a can for aromatic substances with a height-displaceable device for minimizing the air volume located above the filling material, in which the device is a base carrying the filling material.

Diese Dose stellt sicher, daß das über dem Füllgut befindliche Luftvolumen stets so klein wie möglich gehalten werden kann. Dadurch wird eine Verwirbelung der Luft und der daraus resultierenden Abtransport von Aromastoffen verhindert.This box ensures that the air volume above the product can always be kept as small as possible. This prevents turbulence in the air and the resulting removal of aromas.

In einer bevorzugten Ausführungsform ist der Boden der Dose durch Verdrehen des Deckels höhenverstellbar. Dazu können Zugeinrichtungen vorgesehen sein, die an einem in der zur Bewegungseinrichtung des Bodens senkrechten Ebene drehbar gelagerten Drehring angebracht sind, wobei der durch die Zugeinrichtungen aufgebrachte tangentiale Zug durch eine )Umlenkeinrichtung in einem Zug in Bewegungsrichtung des Bodens umlenkbar ist.In a preferred embodiment, the bottom of the can is height-adjustable by turning the lid. For this purpose, pulling devices can be provided which are attached to a rotating ring which is rotatably mounted in the plane perpendicular to the moving device of the floor, the tangential pull applied by the pulling devices being deflectable in one pull in the direction of movement of the floor by a deflection device.

Eine bevorzugte Ausführungsform der Dose weist mindestens drei Zugeinrichtungen auf, die alle die gleiche Länge haben ) und mit axialem Versatz an dem Drehring angebracht sein können, wobei die jeweiligen azimutalen Abstände zwischen den Befestigungspunkten der Zugeinrichtungen am Drehring und den dazugehöhrigen Umlenkeinrichtungen zum Ausgleich des axialen Versatzes unterschiedlich groß sind.A preferred embodiment of the box has at least three pulling devices, which all have the same length) and can be attached to the rotating ring with an axial offset, the respective azimuthal distances between the fastening points of the pulling devices on the rotating ring and the associated deflection devices for compensation of the axial offset are of different sizes.

In einer weiteren bevorzugten Ausführungsform der Dose kann der Boden sowohl mittels oberer Dreh- und Zugeinrichtungen nach oben als auch mittels unterer Dreh- und Zugeinrichtungen nach unten bewegt werden. In einer weiteren bevorzugten Ausführungsform weist der Boden eine Dichteinrichtung auf, die vorzugsweise nach oben gerichtet ist und sich bei Belastung von oben an die Innenwand der Dose anlegt.In a further preferred embodiment of the can, the base can be moved upwards by means of upper rotating and pulling devices as well as by means of lower rotating and pulling devices. In a further preferred embodiment, the base has a sealing device, which is preferably directed upwards and, when loaded from above, bears against the inner wall of the can.

In einer weiteren bevorzugten Ausführungsform der Dose verjüngt sich der Innendurchmesser des zur Aufnahme des Füllgutes bestimmten Raumes am oberen Ende, um bei der Aufwärtsbewegung des Bodens die oberen Lagen des Füllguts in die Mitte zubringen und somit ein Festbacken des Füllgutes in den Ecken zu verhindern.In a further preferred embodiment of the can, the inside diameter of the space intended for receiving the filling material tapers at the upper end in order to bring the upper layers of the filling material into the middle when the bottom moves upward and thus prevent the filling material from sticking in the corners.

Der Deckel der Dose kann zur Betätigung des Drehringes verwendet werden. Dazu weist der Deckel vorzugsweise mindestens zwei Mitnehmereinrichtungen auf, die mit entsprechenden Gegenstücken im Drehring zusammenwirken und gleichzeitig die winkelmäßige Lage des Deckels im Verhältnis zum Drehring definieren. Die Mitnehmereinrichtung und die entsprechenden Gegenstücke können so ausgebildet sein, daß der Drehring durch den Deckel nur in eine Richtung drehbar ist. Die Mitnehmereinrichtungen können Überlastsicherungen aufweisen, die Ansprechen, bevor durch den Deckel ein die Zugeinrichtungen überbeanspruchendes Drehmoment auf den Drehring aufgebracht wird.The lid of the box can be used to operate the rotating ring. For this purpose, the cover preferably has at least two driver devices which interact with corresponding counterparts in the rotating ring and at the same time define the angular position of the cover in relation to the rotating ring. The driver device and the corresponding counterparts can be designed such that the rotary ring can only be rotated in one direction by the cover. The driver devices can have overload safeguards that respond before a torque that overloads the pulling devices is applied to the rotating ring through the cover.

In einer weiteren bevorzugten Ausführungsform weist die Dose eine Füllstandsanzeige auf, die insbesondere aus einem mit dem Deckel in Verbindung stehenden Zeiger und einer auf der Außenseite der Dose angebrachten Markierung besteht. Die winkelmäßige und axiale Lage des Drehrings kann durch geeignete Fixierungseinrichtungen, die mit Gegenstücken in der Dosenwand zusammenwirken, fixiert werden.In a further preferred embodiment, the can has a fill level indicator, which in particular consists of a pointer connected to the lid and a mark made on the outside of the can. The angular and axial position of the rotating ring can be fixed by suitable fixing devices that interact with counterparts in the can wall.

In einer weiteren bevorzugten Ausführungsform kann das untere Ende der Dose eine Luftaustrittsöffnung aufweisen, um die Abwärtsbewegung des beweglichen-Bodens, die vor einer Neubefüllung der Dose notwendig ist, zu erleichtern.In a further preferred embodiment, the lower end of the can can have an air outlet opening in order to facilitate the downward movement of the movable base, which is necessary before the can is refilled.

Die Dose kann in einer weiteren bevorzugten Ausführungsform Führungsnuten oder -rinnen für die Zugeinrichtungen aufweisen.In a further preferred embodiment, the can can have guide grooves or channels for the pulling devices.

Die Zugeinrichtungen sind in einer bevorzugten Ausführungsform der Dose als Kunststoffäden ausgebildet, die an beiden Enden jeweils eine erste Querschnittsvergrößerung und am Ende der ersten Querschnittsvergrößerung eine zweite Querschnittsvergrößerung aufweisen.In a preferred embodiment of the can, the pulling devices are designed as plastic threads, each having a first cross-sectional enlargement at both ends and a second cross-sectional enlargement at the end of the first cross-sectional enlargement.

Der Deckel der Dose weist in einer weiteren bevorzugten Ausführungsform der Erfindung eine bis an das Füllgut heranreichende Fläche auf. Diese Fläche kann durch einen Füllkörper oder eine topfförmige Vertiefung des Deckels gebildet werden.In a further preferred embodiment of the invention, the lid of the can has a surface that extends as far as the filling material. This surface can be formed by a filler or a pot-shaped recess in the lid.

Der Deckel weist in einer weiteren bevorzugten Ausführungsform einen über die Dosenaußenseite ragenden Rand auf, der mit Schlitzen versehen ist und durch Federkraft auf der Dose gehalten wird. Dadurch läßt sich der Deckel auf der Dose leicht drehen und durch einfachen Zug auch entfernen.In a further preferred embodiment, the lid has an edge which projects beyond the outside of the can and is provided with slots and is held on the can by spring force. This allows the lid on the can to be easily turned and removed with a simple pull.

Weitere Vorteile, Merkmale und Anwendungsmöglichkeiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels in Verbindung mit der Zeichnung. Darin zeigen:

  • Fig. 2 einen Querschnitt entlang der Linie BB der Fig. l,
  • Fig. 3 eine perspektivische Ansicht des Drehringes, an dem die Zugeinrichtungen befestigt sind, und
  • Fig. 4' eine perspektivische Außenansicht der Dose.
Further advantages, features and possible uses of the invention result from the following description of an exemplary embodiment in conjunction with the drawing. In it show:
  • 1 shows a longitudinal section through the can,
  • 2 shows a cross section along the line BB of FIG. 1,
  • Fig. 3 is a perspective view of the rotary ring on which the traction devices are attached, and
  • Fig. 4 'is an external perspective view of the can.

Die Dose ist ein an beiden Enden offener Hohlzylinder, in dem sich ein Boden 10 befindet. Dieser Boden kann vorzugsweise als Kolben ausgebildet sein. Dieser Boden trägt eine nach oben weisende Dichtlippe 11, die an der Dosenwand 1 anliegt. Die Dichtlippe 11 wird durch ihre eigene Elastizität und durch das Gewicht des Füllgutes an die Dosenwand 1 gepreßt.The box is a hollow cylinder open at both ends, in which a bottom 10 is located. This base can preferably be designed as a piston. This bottom carries an upwardly facing sealing lip 11, which bears against the can wall 1. The sealing lip 11 is pressed against the can wall 1 by its own elasticity and by the weight of the filling material.

Der Boden wird mittels Zugeinrichtungen 3 bewegt, die in Nuten 2 in der Dosenwand 1 geführt werden. Die Zugeinrichtungen sind beispielsweise Kunststoffäden, die an beiden Enden eine erste Querschnittsvergrößerung und am Ende der ersten Querschnittsvergrößerung eine zweite Querschnittsvergrößerung aufweisen. Dadurch lassen sie sich bei der Fertigung leicht am Boden befestigen, der für diese Befestigung eine Einrichtung, beispielweise einen Vorsprung aufweist, in der sich ein Schlitz befindet, dessen Breite dem Durchmesser des mittleren Teils des Kunststoffadens entspricht und an dessen unteren Ende sich eine Bohrung befindet, deren Durchmesser gleich der ersten Querschnittsvergrößerung des Kunststoffadens ist. Durch diese Einrichtung kann der Kunststoffaden leicht fixiert werden.The floor is moved by means of traction devices 3, which are guided in grooves 2 in the can wall 1. The traction devices are, for example, plastic threads which have a first cross-sectional enlargement at both ends and a second cross-sectional enlargement at the end of the first cross-section enlargement. This allows them to be easily attached to the floor during manufacture, which has a device for this attachment, for example a projection, in which there is a slot, the width of which corresponds to the diameter of the central part of the plastic cord and a bore is located at the lower end thereof whose diameter is equal to the first cross-sectional enlargement of the plastic filament. With this device, the plastic thread can be easily fixed.

Am oberen Ende der Dose befindet sich ein fester Ring 4, in dem ein beweglicher Drehring 5 drehbar in der Ebene senkrecht zur Bewegungsrichtung des Bodens gelagert ist. Die Zugeinrichtungen 3 werden durch Schlitze 'in einem festen Ring 4 geführt und sind am Drehring 5 angebracht. Der feste Ring 4 erfüllt damit die Funktion einer Umlenkeinrichtung. Durch Drehung des Drehringes 5 werden die Zugeinrichtungen 3 auf diesen Drehring 5 aufgewickelt. Mittels des als Umlenkeinrichtung dienenden festen Ringes 4 wird der tangentiale Zug, dem die Zugeinrichtung durch die Drehung des Drehringes 5 ausgesetzt sind, in einen axialen Zug umgesetzt, und somit der Boden axial bewegt. Ein Abdeckring 6 ist vorgesehen, damit die Zugeinrichtungen 3 sich nicht unbeabsichtigt vom Drehring 5 entfernen können. Der feste Ring 4 weist an seiner dem Boden 10 zugewandten Seite eine Abschrägung auf, wodurch der Innendurchmesser des zur Aufnahme des Füllgutes bestimmten Raumes verringert wird. Dadurch wird bei der Aufwärtsbewegung des Bodens das Füllgut am oberen Ende der Dose nach Innen gedrückt und es kann sich kein Füllgut in der oberen Kante der Dose festsetzen.At the upper end of the box there is a fixed ring 4 in which a movable rotary ring 5 is rotatably mounted in the plane perpendicular to the direction of movement of the base. The traction devices 3 are guided through slots' in a fixed ring 4 and are attached to the rotating ring 5. The fixed ring 4 thus fulfills the function of a deflection device. By turning the rotating ring 5, the pulling devices 3 are wound onto this rotating ring 5. By means of the fixed ring 4 serving as a deflection device, the tangential pull, to which the pulling device is exposed due to the rotation of the rotating ring 5, is converted into an axial pull, and thus the floor moves axially. A cover ring 6 is provided so that the pulling devices 3 cannot inadvertently move away from the rotating ring 5. The fixed ring 4 has a bevel on its side facing the base 10, as a result of which the inside diameter of the space intended for receiving the filling material is reduced. As a result, the filling material at the upper end of the can is pressed inwards during the upward movement of the base and no filling material can become lodged in the upper edge of the can.

Am unteren Ende der Dose sind ähnlich zu den oberen Zugeinrichtungen ausgestaltete untere Zugeinrichtungen vorgesehen. Ein Abdeckring 14 ist baugleich mit dem oberen Abdeckring 6, ein unterer Drehring 13 ist baugleich mit dem oberen Drehring 5 und ein unterer fester Ring 12, der ebenfalls die Funktion einer Umlenkeinrichtung erfüllt, entspricht dem oberen festen Ring 4, lediglich die Abschrägung auf der dem Boden zugewandten Seite ist hier nicht notwendig.At the lower end of the box, lower pulling devices are provided which are similar to the upper pulling devices. A cover ring 14 is identical to the upper cover ring 6, a lower rotary ring 13 is identical to the upper rotary ring 5 and a lower fixed ring 12, which also fulfills the function of a deflection device, corresponds to the upper fixed ring 4, only the bevel on the Bottom-facing side is not necessary here.

Der feste Ring 4, 12 kann durch geeignete Fixierungseinrichtungen, beispielsweise Nuten und Vorsprünge in seiner winkelmäßigen und axialen Lage gegenüber der Dosenwand 1 fixiert werden.The fixed ring 4, 12 can be fixed in its angular and axial position relative to the can wall 1 by means of suitable fixing devices, for example grooves and projections.

Aus Vereinfachungsgründen bei der Montage empfiehlt es sich, alle Zugeinrichtungen 3 mit gleicher Länge vorzusehen. Bringt man nun alle Zugeinrichtungen in der gleichen axialen Höhe auf den Drehring 5, 13 an, kann es bei Drehungen des Drehringes 5, 13 zu unerwünschten Verwicklungen der Zugeinrichtungen auf dem Drehring kommen, da mehrere Lagen der Zugeinrichtungen 3 aufeinander zu liegen kommen können. Aus diesem Grund ist es von Vorteil, die Zugeinrichtungen in unterschiedlichen axialen Höhen am Drehring anzubringen. Um trotzdem beim Zug den Boden 10 nicht zu verkanten, d.h. in einer Ebene zu halten, die senkrecht zur Längsachse der Dose liegt, muß man diesen axialen Versatz ausgleichen. Dies geschieht vorteilhafterweise dadurch, daßFor reasons of simplification during assembly, it is advisable to provide all pulling devices 3 of the same length. If all pulling devices are now attached to the rotating ring 5, 13 at the same axial height, undesired entanglement of the pulling devices on the rotating ring can occur when the rotating ring 5, 13 rotates, since several layers of the pulling devices 3 can lie on top of one another. For this reason, it is advantageous to attach the pulling devices to the rotating ring at different axial heights. In order not to tilt the floor 10 during the train, ie to keep it in a plane that is perpendicular to the longitudinal axis of the box, one has to compensate for this axial offset. This is advantageously done in that

Befestigungspunkte 17 der Zugeinrichtungen in azimutaler Richtung auf dem Drehring 5 so versetzt werden, daß sie den axialen Versatz ausgleichen. Befindet sich beispielsweise der Boden 10 in seiner untersten Lage, dann liegt der Befestigungspunkt 17 der Zugeinrichtung 3, die am weitesten oben auf dem Drehring 5 angebracht ist, gegenüber dem zugeordnetem Schlitz in dem festen Ring 4. Die Befestigungspunkte 17 der anderen Zugeinrichtungen 3, die auf dem Drehring 5 weiter unten angeordnet sind, liegen in Drehrichtung von dem zugeordnetem Schlitz in dem festen Ring 4 soweit entfernt, daß sie den axialen Versatz ausgleichen.Fastening points 17 of the traction devices are offset in the azimuthal direction on the rotary ring 5 so that they compensate for the axial offset. If, for example, the bottom 10 is in its lowermost position, then the fastening point 17 of the pulling device 3, which is attached to the top of the rotating ring 5, lies opposite the associated slot in the fixed ring 4. The fastening points 17 of the other pulling devices 3, are arranged further down on the rotating ring 5, are so far removed in the direction of rotation from the associated slot in the fixed ring 4 that they compensate for the axial offset.

Der Drehring 5 kann mit Hilfe eines Dosendeckels 7 bewegt werden. Zu diesem Zweck weist der Dosendeckel Mitnehmereinrichtungen 16 auf, die mit zugehörigen Gegenstücken 15 im Drehring 5 zusammenwirken. Diese Gegenstücke 15 können als Vorsprünge mit steilen Vorderflanken und flach abfallenden Rückenflanken ausgebildet sein, so daß der Drehring durch den Deckel 7 nur in eine Richtung drehbar ist. Wird der Deckel in die andere Richtung gedreht, finden die Mitnehmereinrichtungen 16 im Deckel keinen Widerstand, sondern gleiten auf der flach abfallenden Flanke der Vorsprünge nach oben. Die Mitnehmereinrichtungen 16 im Deckel weisen vorteilhafterweise Überlastsicherungen auf, die ansprechen, bevor durch den Deckel 7 auf den Drehring 5, 13 ein Moment aufgebracht wird, das die Zugeinrichtungen 3 überbeansprucht. Durch geeignete Maßnahmen, beispielweise in dem zwei Vorsprünge 15 im Drehring 5, 13 vorgesehen sind, die auf zwei getrennten Kreisringen liegen, kann die winkelmäßige Lage des Deckels in Bezug auf den Drehring 5, 13 definiert werden.The rotating ring 5 can be moved with the aid of a can lid 7. For this purpose, the can lid has driver devices 16 which cooperate with associated counterparts 15 in the rotating ring 5. These counterparts 15 can be designed as projections with steep front flanks and gently sloping back flanks, so that the rotating ring can only be rotated in one direction by the cover 7. If the lid is rotated in the other direction, the driver devices 16 find no resistance in the lid, but slide upwards on the gently sloping flank of the projections. The driver devices 16 in the cover advantageously have overload protection devices which respond before a moment is applied to the rotary ring 5, 13 by the cover 7, which overstresses the pulling devices 3. The angular position of the cover with respect to the rotary ring 5, 13 can be defined by suitable measures, for example in which two projections 15 are provided in the rotary ring 5, 13, which lie on two separate circular rings.

Jede Höhe des Bodens 10 in der Dose entspricht einer bestimmten winkelmäßigen Stellung des Drehringes 5. Da der Deckel 7 gegenüber dem Drehring 5 eine definierte Lage einnimmt, gibt die Stellung des Deckels 7 einen Aufschluß darüber, in welcher Höhe der Boden 10 steht. Dies wird für eine Füllstandsanzeige ausgenutzt, bei der ein auf dem Deckel 7 befindlicher Zeiger 18 auf eine auf der Dose außen angebrachte Markierung 19 weist, an der man direkt den Füllstand der Dose ablesen kann.Each height of the base 10 in the can corresponds to a specific angular position of the rotating ring 5. Since the cover 7 assumes a defined position relative to the rotating ring 5, the position of the cover 7 provides information about the height of the base 10. This is used for a level indicator in which one on the The pointer 7 located on the lid 7 points to a mark 19 on the outside of the can, from which the fill level of the can can be read directly.

Der Deckel 7 kann eine topfförmige Vertiefung oder ein Füllstück 21 aufweisen, dessen untere Fläche bis auf das Füllgut reicht. Dadurch wird eine zusätzliche Verminderung des über dem Füllgut befindlichen Luftvolumens erreicht.The lid 7 can have a cup-shaped depression or a filler 21, the lower surface of which extends to the filling material. This results in an additional reduction in the air volume above the product.

Der Deckel 7 weist einen über die Außenwand der Dose ragenden Rand 8 auf. Dieser Rand weist Schlitze 22 auf. Dadurch können die einzelnen Abschnitte des Deckelrandes 8, die durch die Schlitze 22 gebildet werden, mit einer gewissen Federkraft versehen werden, die den Deckel 7 auf der Dose halten. Der Deckel 7 kann dann leicht gedreht und durch einfachen Zug abgenommen werden.The lid 7 has an edge 8 projecting over the outer wall of the can. This edge has slots 22. As a result, the individual sections of the lid edge 8, which are formed by the slots 22, can be provided with a certain spring force, which hold the lid 7 on the can. The lid 7 can then be easily rotated and removed by a simple pull.

Die untere Stirnseite der Dose, die im wesentlichen aus dem unteren festen Ring 12 gebildet wird, weist eine Öffnung auf, durch die die Luft beim Abwärtsbewegen des Bodens 10 entweichen kann. Die Aufwärtsbewegung des Bodens, die nur nach Entnahme von Füllgut erfolgt, erfolgt in der Regel so langsam, daß die überschüssige Luft durch die in geringer Zahl vorhandenen undichten Stellen zwischen Deckel 7 und Dose entweichen kann. Ist die Dose vollständig entleert, d.h. ist der Boden 10 an seiner obersten Position angelangt, ist es zur Wiederfüllung der Dose notwendig, den Boden wieder in seine unterste Position zu bringen. Zu diesem Zweck wird der Deckel 7 auf die Unterseite der Dose gebracht. Durch einfaches Drehen des Deckels 7, der mit den Vorsprüngen 15 des unteren Drehringes 13 zusammenwirkt, wird der Boden 10 nach unten gezogen. Da die Dichtlippe 11 des Bodens 10 nach oben gerichtet ist, wird sie bei dieser Betätigung des Bodens 10 nicht beschädigt. Zusätzlich zu der Dichtlippe 11 kann unterhalb des Bodens 10 noch ein zweiter Dichtring angebracht sein.The lower end face of the can, which is essentially formed from the lower fixed ring 12, has an opening through which the air can escape when the base 10 is moved downwards. The upward movement of the base, which takes place only after the filling material has been removed, is generally so slow that the excess air can escape through the small number of leaks between the lid 7 and the can. Is the can completely empty, i.e. once the bottom 10 has reached its uppermost position, to refill the can it is necessary to return the bottom to its lowest position. For this purpose, the lid 7 is placed on the underside of the can. By simply turning the cover 7, which cooperates with the projections 15 of the lower rotating ring 13, the bottom 10 is pulled downwards. Since the sealing lip 11 of the base 10 is directed upwards, it is not damaged when the base 10 is actuated. In addition to the sealing lip 11, a second sealing ring can also be attached below the base 10.
