Definitions
- the present invention relates to a plastic bucket and lid with a collar-shaped spacer and a concealed clamp closure consisting of a bucket or container which has an outwardly projecting collar and a centering shoulder thereon, a pressure flange and an axially pointing sealing lip away from the bucket opening and a lid with an outer centering web and a sealing groove, which is formed by the outer web, top flange and inner web.
- the bucket and the lid have a specific design, so that i.a. a protective space is formed which protects the sealing lip in the case of pails stacked one inside the other and other advantages in stacking, storage, emptying of the containers and the like can be achieved.
- Plastic buckets are used in many areas of industry and trade.
- the automation and development of fully automatic production lines with control centers also places special demands on the packaging - such as buckets and lids.
- a bucket is known from utility model application 8335866, which can be centered in the stack relative to one another and used in robot magazines in an aligned manner. With the bucket lids according to utility model registration 83161777.3, centering bars enable good magazine guidance.
- the disadvantage of such packaging buckets and lids is the free accessibility of the bottom catch segments of the lid and bucket. They move during transport Pallet stack frequently and the lids are pushed off.
- Another disadvantage is the empty stacked buckets because the spaces between the bucket collars require special mechanisms for lifting and fixing the carrying handle.
- these cavities as dirt corners - particularly in the food sector - are disadvantageous. Since mostly high-sealing closures are required, damage to the edge of the bucket and therefore leaks are always possible with stacked buckets. The spacers of the conventional buckets adversely press on the important closure parts.
- the present invention is based on a bucket and lid, which the above. Avoids disadvantages, and has improved properties compared to the known closable buckets. However, once a feature is changed on buckets with a closable lid to achieve improvements, disadvantages often occur with other properties or parts, so that a combination of features often has to be changed in order to reduce or avoid disadvantages in other places.
- a plastic bucket or plastic container that has an outwardly projecting collar (5) and a centering shoulder (4), a pressure flange (2) and a sealing lip (3) that points axially away from the bucket opening and one adapted cover (20) with an outer centering web (26) and a sealing groove (23), which is formed by the outer web (25), head flange (24) and inner web (22).
- the collar (5) forms a protective space (6) with the bucket wall (1) and the sealing lip (3) and the centering shoulder (4) are at stacked buckets protected hidden.
- the collar (5) is designed with a completely or partially circumferential same height as a hollow cylinder or as a closed cylinder and has the same diameter with the centering web (26) of the cover (20) in the closed state and forms a common outer cylindrical surface (X) the centering web (26) with the outer web (25), the top flange (24) and the inner web (22) surrounds the sealing groove (23) in a protective manner.
- the lid according to the invention has the same outer diameter with the bucket collar and is flush with it. As a result, there are no starting points that the lid could be accidentally pushed off. Bucket and lid form a smooth cylindrical outer surface. The outer contours of the bucket and lid are therefore difficult or impossible to open without additional handling or tools.
- the diameter of the circumferential sealing lip (3) arranged on the upper edge of the container is smaller than the inner diameter of the centering web (26) of the lid and the length L 1 of the centering shoulder (4) is greater than the length L 2 of the sealing lip ( 3) and / or the lengths of the centering web (26) and the sealing groove (23) are the same or approximately the same with the lengths or proportions of the centering shoulder (4) and the sealing lip (3).
- the outer diameter of the centering shoulder (4) is a few tenths of a mm (preferably 0.5 to 0.9 mm) smaller than the inner diameter of the centering web (26) and the centering shoulder (4) has at least one bucket latch (12 ), which can be positively locked in the closed state with at least one cover pawl (27) of the centering web (26).
- the sealing lip (3) and the sealing groove (23) have an inclined position and / or the sealing lip is directed outwards, so that (in cross section) the sealing lip measures an acute angle with the vertical axis passing through the center of the bottom of the bucket vertical axis above the bucket opening to the sealing lip).
- the sealing lip and the sealing groove always have a sealing system and function, even with different diameters and manufacturing tolerances of the buckets.
- the outer web (25) is thicker or significantly thicker than the inner web (22) and / or the sealing groove (23) has a narrower gap or a slightly smaller opening width (preferably produced by dimensional shrinkage during manufacture) than the thickness or the cross section of the sealing lip (3), so that in the closed state the sealing groove (23) forms a press fit with the sealing lip (3).
- one or more recessed grips (9) are arranged on the collar (5) of the bucket.
- the recessed grips are preferably with Securing elements (10) covered, whereby according to a preferred embodiment, the securing elements are connected to the collar via a perforation (11) or a material-thinned point, a recess or an incision or a notch, so that the securing segments (10) are only pressed in when they are pressed in perforation (11) and the like, grasping and loosening of the centering web (26) is possible.
- the bucket collar has a concealed recessed grip at one or more points, and if a securing segment is deliberately destroyed and pressed in, the lid can be gripped and released using a perforation, notch and the like.
- locking ribs (8) are formed below the recessed grip (9) in the protective space (6), which are locked or can be locked when the buckets are stacked into one another in the recessed grip (9). This prevents radial rotation of the individual buckets.
- the locking ribs (8) (measured parallel to the central axis of the bucket) are longer than the ribs (7), but the average width of the locking ribs or the average diameter of the preferably radially arranged locking ribs is smaller than the width or the average diameter the radially arranged ribs (7).
- the handles are always aligned in the same place.
- the bucket and lid With a centering shoulder on the bucket and a centering bar on the lid, the bucket and lid are fixed and centered on each other in filling systems and are therefore easy to use on all roll-on or press-sealers. Capping and closing by hand is also easy to do.
- the special arrangement and location of the individual wall elements and the interaction of a sealing lip with a sealing groove result in a high-sealing closure.
- the lid on the bucket again has so-called latches, which represent a high-strength, mechanically resilient closure.
- the actual sealing and closing element of the lid is also protected by the centering bar on the lid and lies in the lower inner part of the lid.
- the cover surface (21) preferably rests on the pressure flange (2) in the closed state and absorbs the weight of stacked buckets and transfers them to the bucket wall (1).
- the centering web (26) of the cover has a downward circumferential cover spring (28) in the form of a tip.
- the collar (5) at the transition to the centering shoulder (4) has a collar groove (29) with a recess adapted to the tip of the cover spring (28) or with a recess adapted to the angles of the cover spring tip (28), which in the closed state of the bucket and cover adjust the centering shoulder (26) and collar (5) and thereby effect an axial and / or radial locking.
- a pressure flange (2) is arranged at a right angle or at an obtuse angle to the bucket wall (measured on the outer bucket wall boundary line or distance, which leads from the bucket bottom to the pressure flange) and the pressure flange (2) surrounds the bucket opening in a ring, whereby the centering bar (4) with the collar (5) immediately and is arranged at right angles to the pressure flange (2).
- the outer web (25) of the lid has a cylindrical outer surface and / or is arranged parallel to the centering web (26) or to the central axis of the bucket passing through the center of the bucket bottom.
- this central axis is also the axis of rotation.
- this central axis is also the axis of rotation.
- the angle between the inner web (22) and the outer web and / or the centering web (measured from the top flange to the bottom of the bucket) is particularly advantageously 5 to 20 °, preferably 10 to 15 °.
- the outer web has a wall thickness 1.5 to 4 times, preferably 2 to 2.5 times, thicker than that of the inner web and / or the cover surface.
- ribs (7) are arranged between the bucket wall (1) and the centering shoulder (4) and the lip (3) is at a distance from the ribs (7) when the buckets are stacked one inside the other in the cavity (6).
- the lower edge of the collar (5) preferably lies on the upper edge of the collar (5) of the bucket arranged underneath.
- the outer edge of the lid preferably the centering web of the lid, is a particularly preferred one Embodiment arranged parallel or approximately parallel to the central axis extending perpendicularly through the center of the bucket bottom and / or lid, the outer edge of the lid having at least two cylindrical or ring-shaped parallel or approximately parallel surfaces of different sizes, the outer web (25) having a smaller diameter passes over a step into the cylindrical parallel collar part, preferably centering web (26) with the larger outside diameter.
- the sealing lip (3) is not arranged directly on the upper bucket wall, but on the pressure flange (2) delimiting the bucket, offset with respect to the inner wall of the bucket, the lower ends of the ribs (7) not being designed as stack stops and / or the length of the ribs (7) (except locking ribs (8) - measured in the vertical direction parallel to the central axis of the bucket and from the lower surface or side of the pressure flange) is smaller than half the length of the collar (5) (measured in the vertical direction parallel to the central axis of the bucket and from the lower surface or side of the pressure flange).
- the sealing lip 3 serves the centering web 26 as a pre-centering.
- the centering shoulder 4 of the bucket and the centering web 26 of the lid are locked. Due to the greater length L 1 of the centering shoulder 4 to the length L 2 of the sealing lip 3, the sealing lip 3 is free at the beginning of the closing, i.e. protected. Only when the centering shoulder 4 and the centering web 26 have been found centrally and have an exact guidance to one another, does the sealing lip 3 snap into the sealing groove 23.
- the lengths of the sealing groove 23 and the centering web 26 of the cover are congruent with the length L 1 and L 2.
- the bucket and lid When closed, the bucket and lid form an outer cylindrical part X of the same diameter. There is thus a closed outer surface.
- the lid cannot be unintentionally removed from the bucket.
- the buckets and lids always meet with this cylindrical outer surface X. It cannot damage the lock. Likewise, no possibility of attack under the lid edge is possible.
- the actual lock and the pawls 12 + 27 are protected inside the outer surface X.
- the centering web (26) of the cover has a downward-running circumferential cover spring (28) in the form of a tip
- the collar (5) has a collar groove (29) with a recess adapted to the tip of the cover spring (28) at the transition to the centering shoulder (4).
Abstract
Description
Die vorliegende Erfindung betrifft einen Kunststoffeimer und Deckel mit kragenförmigem Abstandhalter und verdecktem Klemmverschluß bestehend aus einem Eimer oder Behälter, der einen nach außen stehenden Kragen und daran einen Zentrierabsatz einen Druckflansch sowie eine axial von der Eimeröffnung wegweisende Dichtlippe aufweist und einen Deckel mit einem äußeren Zentriersteg und einer Dichtnut, welche von dem Außensteg, Kopfflansch und Innensteg gebildet wird, besitzt. Der Eimer und der Deckel weisen eine bestimmte Ausbildung auf, so daß u.a. ein Schutzraum gebildet wird, der die Dichtlippe bei ineinandergestapelten Eimern schützt und andere Vorteile bei der Stapelung, Lagerung, bei dem Entleeren der Behälter und dergleichen erzielt werden können.The present invention relates to a plastic bucket and lid with a collar-shaped spacer and a concealed clamp closure consisting of a bucket or container which has an outwardly projecting collar and a centering shoulder thereon, a pressure flange and an axially pointing sealing lip away from the bucket opening and a lid with an outer centering web and a sealing groove, which is formed by the outer web, top flange and inner web. The bucket and the lid have a specific design, so that i.a. a protective space is formed which protects the sealing lip in the case of pails stacked one inside the other and other advantages in stacking, storage, emptying of the containers and the like can be achieved.
Kunststoffeimer werden in vielen Bereichen der Industrie und des Handels eingesetzt. Die Automatisierung und Entwicklung zu vollautomatischen Fertigungsstraßen mit Leitständen, stellt auch an die Packmittel - wie Eimer und Deckel - besondere Anforderungen. So ist aus der Gebrauchsmusteranmeldung 8335866 ein Eimer bekannt, welcher im Stapel zueinander zentriert und in Robotermagazinen ausgerichtet eingesetzt werden kann. Bei den Eimerdeckeln nach Gebrauchsmusteranmeldung 83161777.3 ermöglichen Zentrierstege eine gute Magazinführung. Der Nachteil solcher Verpackungseimer und -Deckel besteht in der freien Zugänglichkeit der Unterrastsegmente des Deckels und Eimers. Beim Transport verschieben sich die Palettenstapel häufig und die Deckel werden abgestoßen. Ein weiterer Nachteil ist bei den leergestapelten Eimern vorhanden, weil die Zwischenräume der Eimerkragen besondere Mechanismen zum Anheben und Fixieren der Tragebügel erfordern. Weiterhin sind diese Hohlräume als Schmutzecken - besonders im Lebensmittelbereich - nachteilig. Da größtenteils hochdichtende Verschlüsse verlangt werden, sind bei gestapelten Eimern immer Beschädigungen des Eimerrandes und dadurch Undichtigkeiten möglich. Die Abstandhalter der herkömmlichen Eimer drücken nachteilig auf die wichtigen Verschlußteile.Plastic buckets are used in many areas of industry and trade. The automation and development of fully automatic production lines with control centers also places special demands on the packaging - such as buckets and lids. A bucket is known from utility model application 8335866, which can be centered in the stack relative to one another and used in robot magazines in an aligned manner. With the bucket lids according to utility model registration 83161777.3, centering bars enable good magazine guidance. The disadvantage of such packaging buckets and lids is the free accessibility of the bottom catch segments of the lid and bucket. They move during transport Pallet stack frequently and the lids are pushed off. Another disadvantage is the empty stacked buckets because the spaces between the bucket collars require special mechanisms for lifting and fixing the carrying handle. Furthermore, these cavities as dirt corners - particularly in the food sector - are disadvantageous. Since mostly high-sealing closures are required, damage to the edge of the bucket and therefore leaks are always possible with stacked buckets. The spacers of the conventional buckets adversely press on the important closure parts.
Der vorliegenden Erfindung liegt ein Eimer und Deckel zugrunde, der die o.a. Nachteile vermeidet, und gegenüber den bekannten verschließbaren Eimern verbesserte Eigenschaften hat. Sobald man jedoch an Eimern mit verschließbarem Deckel ein Merkmal ändert um Verbesserungen zu erzielen, treten häufig Nachteile bei anderen Eigenschaften oder Teilen auf, so daß häufig eine Kombination von Merkmalen geändert werden muß, um Nachteile an anderen Stellen zu verringern oder zu vermeiden.The present invention is based on a bucket and lid, which the above. Avoids disadvantages, and has improved properties compared to the known closable buckets. However, once a feature is changed on buckets with a closable lid to achieve improvements, disadvantages often occur with other properties or parts, so that a combination of features often has to be changed in order to reduce or avoid disadvantages in other places.
Erfindungsgemäß wurde festgestellt, daß diesen Anforderungen ein Kunststoffeimer oder Kunststoffbehälter gerecht wird, der einen nach außen stehenden Kragen (5) und daran einen Zentrierabsatz (4), einen Druckflansch (2) sowie eine axial von der Eimeröffnung wegweisende Dichtlippe (3) aufweist und einen angepaßten Deckel (20) mit einem äußeren Zentriersteg (26) und einer Dichtnut (23), welche von dem Außensteg (25), Kopfflansch (24) und Innensteg (22) gebildet wird, besitzt. Gemäß der Erfindung bildet der Kragen (5) mit der Eimerwandung (1) einen Schutzraum (6) und die Dichtlippe (3) und der Zentrierabsatz (4) sind bei ineinandergestapelten Eimern geschützt verdeckt. Dabei sind der Kragen (5) mit ganz oder teilweise umlaufender gleicher Höhe hohlzylinderänlich oder als geschlossener Zylinder ausgebildet und hat mit dem Zentriersteg (26) des Deckels (20) in verschlossenem Zustand einen gleichen Durchmesser und bieldet eine gemeinsame äußere zylindrische Fläche (X) wobei der Zentriersteg (26) mit dem Außensteg (25), dem Kopfflansch (24) und dem Innensteg (22) die Dichtnut (23) schützend umgibt.According to the invention, it was found that these requirements are met by a plastic bucket or plastic container that has an outwardly projecting collar (5) and a centering shoulder (4), a pressure flange (2) and a sealing lip (3) that points axially away from the bucket opening and one adapted cover (20) with an outer centering web (26) and a sealing groove (23), which is formed by the outer web (25), head flange (24) and inner web (22). According to the invention, the collar (5) forms a protective space (6) with the bucket wall (1) and the sealing lip (3) and the centering shoulder (4) are at stacked buckets protected hidden. The collar (5) is designed with a completely or partially circumferential same height as a hollow cylinder or as a closed cylinder and has the same diameter with the centering web (26) of the cover (20) in the closed state and forms a common outer cylindrical surface (X) the centering web (26) with the outer web (25), the top flange (24) and the inner web (22) surrounds the sealing groove (23) in a protective manner.
Schmutzecken, Beschädigung des Eimerrandes und dergleichen werden bei den erfindungsgemäßen Eimern weitgehend vermieden, da der Eimer somit einen oben umlaufenden Kragen hat, welcher als Abstandhalter den Verschlußteil des Eimers rundum schützend überdeckt, wenn die Eimer ineinander gestapelt sind. Es kann nicht zu Beschädigungen des Verschlußteiles kommen und der dichtende Verschlußwulst wird nicht durch Abstandhalter deformiert. Der geschlossene Kragen vermeidet ein Unterhaken und Festklemmen der Tragebügel.Dirt corners, damage to the edge of the bucket and the like are largely avoided in the buckets according to the invention, since the bucket thus has an all-round collar which, as a spacer, covers the closure part of the bucket in a protective manner when the buckets are stacked one inside the other. There can be no damage to the closure part and the sealing sealing bead is not deformed by spacers. The closed collar prevents hooking and jamming of the carrying handle.
Der erfindungsgemäße Deckel hat mit dem Eimerkragen einen gleichen Außendurchmesser und schließt bündig ab. Dadurch gibt es keine Ansatzpunkte, daß der Deckel unbeabsichtigt abgestoßen werden könnte. Eimer und Deckel bilden eine glatte zylindrische Außenfläche. Die Außenkonturen von Eimer und Deckel sind damit ohne zusätzliche Handhabe oder ohne Hilfsmittel nicht oder nur schwer zu öffnen.The lid according to the invention has the same outer diameter with the bucket collar and is flush with it. As a result, there are no starting points that the lid could be accidentally pushed off. Bucket and lid form a smooth cylindrical outer surface. The outer contours of the bucket and lid are therefore difficult or impossible to open without additional handling or tools.
Nach einer bevorzugten Ausführungsform der Erfindung ist der Durchmesser der am oberen Behälterrand angeordneten umlaufenden Dichtlippe (3) kleiner als der innere Durchmesser des Zentriersteges (26) des Deckels und die Länge L 1 des Zentrierabsatzes (4) größer als die Länge L 2 der Dichtlippe (3) und/oder die Längen des Zentriersteges (26) und der Dichtnut (23) sind gleich oder annähernd gleich mit den Längen oder Proportionen des Zentrierabsatzes (4) und der Dichtlippe (3). Dadurch wird bei lose aufgelegten Deckel (20) auf den Eimern eine Vorzentrierung für den Verschlußvorgang bewirkt. Der äußere Durchmesser des Zentrierabsatzes (4) ist bei dem erfindungsgemäßen Eimern um einige Zehntel mm, (vorzugsweise 0,5 bis 0,9 mm) kleiner als der Innendurchmesser des Zentriersteges (26) und der Zentrierabsatz (4) hat mindestens eine Eimerklinke (12), welche mit mindestens einer Deckelklinke (27) des Zentriersteges (26) im verschlossenen Zustand kraftschlüssig einrastbar ist.According to a preferred embodiment of the invention, the diameter of the circumferential sealing lip (3) arranged on the upper edge of the container is smaller than the inner diameter of the centering web (26) of the lid and the
Nach einer weiteren bevorzugten Ausführungsform haben die Dichtlippe (3) und die Dichtnut (23) eine Schräglage und/oder die Dichtlippe ist nach außen gerichtet, so daß (im Querschnitt) die Dichtlippe einen spitzen Winkel mit der durch den Eimerbodenmittelpunkt gehende senkrechte Achse (gemessen senkrechte Achse oberhalb der Eimeröffnung zur Dichtlippe) bildet. Dadurch haben die Dichtlippe und die Dichtnut auch bei unterschiedlichen Durchmessern und Fertigungstoleranzen der Eimer immer eine dichtende Anlage und Funktion.According to a further preferred embodiment, the sealing lip (3) and the sealing groove (23) have an inclined position and / or the sealing lip is directed outwards, so that (in cross section) the sealing lip measures an acute angle with the vertical axis passing through the center of the bottom of the bucket vertical axis above the bucket opening to the sealing lip). As a result, the sealing lip and the sealing groove always have a sealing system and function, even with different diameters and manufacturing tolerances of the buckets.
Nach einer bevorzugten Ausführungsform ist der Außensteg (25) dicker oder wesentlich dicker als der Innensteg (22) und/oder die Dichtnut (23) weist einen engeren Spalt oder eine etwas geringere Öffnungsweite (vorzugsweise hergestellt durch Maßschwindung bei der Fertigung) auf als die Dicke bzw. der Querschnitt der Dichtlippe (3), so daß im verschlossenen Zustand die Dichtnut (23) einen Klemmsitz mit der Dichtlippe (3) bildet.According to a preferred embodiment, the outer web (25) is thicker or significantly thicker than the inner web (22) and / or the sealing groove (23) has a narrower gap or a slightly smaller opening width (preferably produced by dimensional shrinkage during manufacture) than the thickness or the cross section of the sealing lip (3), so that in the closed state the sealing groove (23) forms a press fit with the sealing lip (3).
Nach einer vorzugsweisen Ausführungsform sind an dem Kragen (5) des Eimers ein oder mehrere Griffmulden (9) angeordnet. Die Griffmulden sind vorzugsweise mit Sicherungselementen (10) verdeckt, wobei nach einer bevorzugten Ausführungsform die Sicherungselemente über eine Perforierung (11) oder eine materialverdünnte Stelle, einer Vertiefung oder einem Einschnitt oder einer Einkerbung mit dem Kragen verbunden sind, so daß erst bei dem Eindrücken der Sicherungssegmente (10) über eine Perforierung (11) und dergleichen ein Unterfassen und Lösen des Zentriersteges (26) möglich ist. Somit hat der Eimerkragen an einer oder mehreren Stellen eine verdeckte Griffmulde, und bei gezieltem Zerstören und Eindrücken eines Sicherungssegmentes kann der Deckel über eine Perforierung, Einkerbung und dergleichen untergriffen und gelöst werden.According to a preferred embodiment, one or more recessed grips (9) are arranged on the collar (5) of the bucket. The recessed grips are preferably with Securing elements (10) covered, whereby according to a preferred embodiment, the securing elements are connected to the collar via a perforation (11) or a material-thinned point, a recess or an incision or a notch, so that the securing segments (10) are only pressed in when they are pressed in perforation (11) and the like, grasping and loosening of the centering web (26) is possible. Thus, the bucket collar has a concealed recessed grip at one or more points, and if a securing segment is deliberately destroyed and pressed in, the lid can be gripped and released using a perforation, notch and the like.
Nach einer weiteren bevorzugten Ausführungsform sind unterhalb der Griffmulde (9) im Schutzraum (6) Arretierrippen (8) angeformt, welche beim Ineinanderstapeln der Eimer in die Griffmulde (9) arretiert oder arretierbar sind. Dadurch wird eine radiale Verdrehung der einzelnen Eimer ausgeschlossen. Die Arretierrippen greifen oder tauchen bei dem Ineinanderstapeln der Eimer in die Griffmulde ein. Nach einer bevorzugten Ausführungsform sind die Arretierrippen (8) (gemessen parallel zur Eimerzentralachse) länger als die Rippen (7), jedoch ist dabei die durchschnittliche Breite der Arretierrippen oder der durchschnittliche Durchmesser der vorzugsweise radial angeordneten Arretierrippen kleiner als die Breite bzw. der durchschnittliche Durchmesser der radial angeordneten Rippen (7). Die Tragebügel sind damit immer auf der gleichen Stelle ausgerichtet. Mit einem Zentrierabsatz am Eimer und einem Zentriersteg am Deckel werden Eimer und Deckel auf Abfüllanlagen zueinander fixiert und zentriert und sind damit auf allen Aufroll- oder Aufdrückverschließmaschinen einfach zu handhaben. Ebenfalls ist eine Verdeckelung und Verschließung von Hand simpel zu bewerkstelligen. Die besondere Anordnung und Lage der einzelnen Wandelemente und das Zusammenwirken einer Dichtlippe mit einer Dichtnut ergeben einen hochdichtenden Verschluß. Um größtmögliche Toleranzen bei der Eimer- und Deckelfertigung zu ermöglichen, hat der Deckel zum Eimer noch einmal sogenannte Klinken, die einen hochfesten, mechanisch belastbaren Verschluß darstellen.According to a further preferred embodiment, locking ribs (8) are formed below the recessed grip (9) in the protective space (6), which are locked or can be locked when the buckets are stacked into one another in the recessed grip (9). This prevents radial rotation of the individual buckets. The locking ribs grip or dip into the recessed grip when the buckets are stacked. According to a preferred embodiment, the locking ribs (8) (measured parallel to the central axis of the bucket) are longer than the ribs (7), but the average width of the locking ribs or the average diameter of the preferably radially arranged locking ribs is smaller than the width or the average diameter the radially arranged ribs (7). The handles are always aligned in the same place. With a centering shoulder on the bucket and a centering bar on the lid, the bucket and lid are fixed and centered on each other in filling systems and are therefore easy to use on all roll-on or press-sealers. Capping and closing by hand is also easy to do. The special arrangement and location of the individual wall elements and the interaction of a sealing lip with a sealing groove result in a high-sealing closure. In order to enable the greatest possible tolerances in the bucket and lid production, the lid on the bucket again has so-called latches, which represent a high-strength, mechanically resilient closure.
Das eigentliche dichtende und verschließende Element des Deckels ist ebenfalls durch den Zentriersteg beim Deckel geschützt und liegt im tieferen inneren Teil des Deckels.The actual sealing and closing element of the lid is also protected by the centering bar on the lid and lies in the lower inner part of the lid.
Bevorzugt liegt die Deckelfläche (21) auf dem Druckflansch (2) in geschlossenem Zustand auf und nimmt die Gewichtskräfte von gestapelten Eimern auf und überträgt diese auf die Eimerwandung (1).The cover surface (21) preferably rests on the pressure flange (2) in the closed state and absorbs the weight of stacked buckets and transfers them to the bucket wall (1).
Nach einer anderen bevorzugten Ausführungsform besitzt der Zentriersteg (26) des Deckels eine nach unten gerichtete umlaufende Deckelfeder (28) in Form einer Spitze. Der Kragen (5) hat beim Übergang zum Zentrierabsatz (4) eine Kragennut (29) mit einer der Spitze der Deckelfeder (28) angepaßten Ausnehmung oder mit einer den Winkeln der Spitze der Deckelfeder (28) angepaßten Ausnehmung, welche im geschlossenen Zustand von Eimer und Deckel den Zentrierabsatz (26) und Kragen (5) justieren und dadurch eine axiale und/oder radiale Verriegelung bewirken.According to another preferred embodiment, the centering web (26) of the cover has a downward circumferential cover spring (28) in the form of a tip. The collar (5) at the transition to the centering shoulder (4) has a collar groove (29) with a recess adapted to the tip of the cover spring (28) or with a recess adapted to the angles of the cover spring tip (28), which in the closed state of the bucket and cover adjust the centering shoulder (26) and collar (5) and thereby effect an axial and / or radial locking.
Bevorzugt ist an der Eimeröffnung ein Druckflansch (2) im rechten Winkel oder im stumpfen Winkel zur Eimerwandung (gemessen an der äußeren Eimerwandungsbegrenzungslinie bzw. -strecke, die vom Eimerboden zum Druckflansch führt) angeordnet und der Druckflansch (2) umgibt die Eimeröffnung ringförmig, wobei der Zentriersteg (4) mit dem Kragen (5) unmittelbar und rechtwinklig an den Druckflansch (2) angeordnet ist. Nach einer besonders bevorzugten Ausführungsform hat der Außensteg (25) des Deckels eine zylindrische Außenfläche und/oder ist parallel zu dem Zentriersteg (26) angeordnet oder zu der durch den Mittelpunkt des Eimerbodens gehenden Zentralachse des Eimers. Diese Zentralachse ist bei Eimern mit rundem Boden, rundem Eimerrand und rundem Deckel (kreisförmigem Deckel) gleichzeitig die Rotationsachse. Bei ovalen Eimern oder anderen Formen, z.b. viereckigen Eimern, stellt sie z.B. die Achse dar, durch die die Symmetrieebenen gehen. Besonders zweckmäßig beträgt der Winkel zwischen dem Innensteg (22) und dem Außensteg und/oder dem Zentriersteg (gemessen vom Kopfflansch zum Eimerboden) 5 bis 20°, vorzugsweise 10 bis 15°. Nach einer vorteilhaften Ausführungsform weist der Außensteg eine gegenüber dem Innensteg und/oder der Deckelfläche 1,5- bis 4-fach, vorzugsweise 2- bis 2,5-fach dickere Wandungsstärke auf. Jedes dieser Merkmale führt zu einer gewissen Verbesserung der Stabilität und auch zu vorteilhaften Eigenschaften des Eimers und angepaßtem Deckel, besonders ist jedoch die Kombination dieser Merkmale vorteilhaft, da eine Zusammenwirkung gegeben ist.Preferably, a pressure flange (2) is arranged at a right angle or at an obtuse angle to the bucket wall (measured on the outer bucket wall boundary line or distance, which leads from the bucket bottom to the pressure flange) and the pressure flange (2) surrounds the bucket opening in a ring, whereby the centering bar (4) with the collar (5) immediately and is arranged at right angles to the pressure flange (2). According to a particularly preferred embodiment, the outer web (25) of the lid has a cylindrical outer surface and / or is arranged parallel to the centering web (26) or to the central axis of the bucket passing through the center of the bucket bottom. For buckets with a round bottom, round bucket rim and round lid (circular lid), this central axis is also the axis of rotation. In the case of oval buckets or other shapes, eg square buckets, it represents, for example, the axis through which the planes of symmetry pass. The angle between the inner web (22) and the outer web and / or the centering web (measured from the top flange to the bottom of the bucket) is particularly advantageously 5 to 20 °, preferably 10 to 15 °. According to an advantageous embodiment, the outer web has a wall thickness 1.5 to 4 times, preferably 2 to 2.5 times, thicker than that of the inner web and / or the cover surface. Each of these features leads to a certain improvement in the stability and also to advantageous properties of the bucket and adapted lid, but the combination of these features is particularly advantageous since there is an interaction.
Nach einer weiteren bevorzugten Ausführungsform sind Rippen (7) zwischen der Eimerwandung (1) und dem Zentrierabsatz (4) angeordnet und die Lippe (3) hat bei ineinander gestapelten Eimern im Hohlraum (6) einen Abstand zu den Rippen (7).According to a further preferred embodiment, ribs (7) are arranged between the bucket wall (1) and the centering shoulder (4) and the lip (3) is at a distance from the ribs (7) when the buckets are stacked one inside the other in the cavity (6).
Bevorzugt liegt die Unterkante des Kragens (5) bei ineinander gestapelten Eimern auf der Oberkante des Kragens (5) des darunter angeordneten Eimers auf.In the case of buckets stacked one inside the other, the lower edge of the collar (5) preferably lies on the upper edge of the collar (5) of the bucket arranged underneath.
Der äußere Deckelrand, vorzugsweise der Zentriersteg des Deckels ist nach einer besonders bevorzugten Ausführungsform parallel oder annähernd parallel zu der durch den Mittelpunkt des Eimerbodens und/oder Deckels senkrecht gehenden Zentralachse angeordnet, wobei der äußere Deckelrand mindestens zwei zylindrische oder ringförmige parallele oder annähernd parallele Flächen mit unterschiedlich großem Durchmesser aufweist, wobei der Außensteg (25) mit kleinerem Durchmesser über eine Stufe in den zylinderförmigen parallelen Kragenteil, vorzugsweise Zentriersteg (26) mit dem größeren Außendurchmesser übergeht.The outer edge of the lid, preferably the centering web of the lid, is a particularly preferred one Embodiment arranged parallel or approximately parallel to the central axis extending perpendicularly through the center of the bucket bottom and / or lid, the outer edge of the lid having at least two cylindrical or ring-shaped parallel or approximately parallel surfaces of different sizes, the outer web (25) having a smaller diameter passes over a step into the cylindrical parallel collar part, preferably centering web (26) with the larger outside diameter.
Nach einer vorteilhaften Ausführungsform ist die Dichtlippe (3) nicht unmittelbar an der oberen Eimerwand angeordnet, sondern auf dem, den Eimer begrenzenden Druckflansch (2), versetzt gegenüber der Eimerinnenwand angeordnet, wobei die unteren Enden der Rippen (7) nicht als Stapelanschläge ausgebildet sind und/oder die Länge der Rippen (7) ist (ausgenommen Arretierungsrippen (8) - gemessen in senkrechter Richtung parallel zur Eimerzentralachse und von der unteren Fläche bzw. Seite des Druckflansches an) kleiner, als die halbe Länge des Kragens (5) (gemessen in senkrechter Richtung parallel zur Eimerzentralachse an und von der unteren Fläche bzw. Seite des Druckflansches an).According to an advantageous embodiment, the sealing lip (3) is not arranged directly on the upper bucket wall, but on the pressure flange (2) delimiting the bucket, offset with respect to the inner wall of the bucket, the lower ends of the ribs (7) not being designed as stack stops and / or the length of the ribs (7) (except locking ribs (8) - measured in the vertical direction parallel to the central axis of the bucket and from the lower surface or side of the pressure flange) is smaller than half the length of the collar (5) (measured in the vertical direction parallel to the central axis of the bucket and from the lower surface or side of the pressure flange).
