Definitions
- the present invention relates to a container for the transport and storage of liquid, viscous or pourable substances, in particular of the intermediate bulk container type, with a base, a side wall and at least one outlet recess in the base and / or the side wall, in which an outlet valve is or can be arranged and which can be closed on the container side by means of a cover.
- IBC intermediate bulk containers
- a container according to the invention for the transport and storage of liquid, viscous or free-flowing substances has a base, a side wall and at least one outlet recess in the base and / or the side wall, in which an outlet valve is or can be arranged.
- the outlet recess can be closed on the outside of the container by means of a cover.
- the outlet recess has a base portion and a closure portion.
- the base section is designed to be attached or attachable to the container.
- the closure section is designed to be able to close the outlet recess.
- the closure section is articulated on the base section so that it can pivot about a rotation axis via a hinge arrangement, so that the closure section can be transferred from a first position, which closes the outlet recess, into a second position, which releases the outlet recess.
- the hinge arrangement is designed to hold or lock the closure section in a self-supporting manner in the second position releasing the outlet recess.
- a pivotable cover / flap for an outlet recess of a container is designed in such a way that its hinge arrangement locks / secures the closure section or the flap of the cover in the open position.
- the holding force of the lock is also designed to be at least so strong that it can hold the closure section in a self-supporting manner against the force of gravity.
- the container according to the invention has the advantage that the cover can be reliably held in an open position when the outlet recess or the outlet valve have to be reached. As a result, the user has both hands free for assembly or operating activities on the valve and in addition, accidental closing of the cover during an assembly process is avoided.
- the locking in the open position is achieved according to the invention by the hinge arrangement of the cover per se. This has the advantage that the entire locking mechanism is part of the cover and can be easily replaced together with the cover in the event of a defect.
- the container can preferably be a large load carrier of the intermediate bulk container type, which has an internal tank with a Has outlet valve, which is housed in an outer support structure made of bottom and side wall.
- the hinge arrangement can have a pretensioning or spring element which is designed to hold the closure body in the second, open position.
- a pretensioning or spring element which is designed to hold the closure body in the second, open position.
- the hinge arrangement can be designed as a bistable hinge which, depending on its relative position with respect to a pressure point, is pretensioned either in the first position closing the outlet recess or in the second position releasing the outlet recess.
- the hinge of the cover can be designed as a so-called snap hinge that it is either snapped into a defined closed position or a defined open position, depending on the relative position of the closure section relative to a pressure point.
- Such an embodiment has the advantage that the cover is always either in a completely closed position or in a defined open position, as a result of which operating errors such as incomplete closing of the cover are avoided.
- the cover can be manufactured in one piece as a plastic component, in particular from a thermoplastic material. This makes it possible to design the cover as a replacement part that is easy to manufacture and inexpensive to manufacture.
- the bistable hinge can be designed as a film hinge arrangement. The implementation of the hinge as a film hinge supports the design of the cover as a simple, one-piece replacement part.
- the cover can preferably be manufactured in one piece as an injection molded part.
- the bistable hinge can be designed as a curved film hinge.
- tension can be brought into the hinge in a simple manner and a snap effect can be generated.
- the film hinge per se forms the prestressing or spring element which prestresses / holds the closure body in the second, open position.
- the bistable hinge can have a resilient bending element or tension element producing a snap action as a pretensioning or spring element.
- the hinge arrangement can have complementary latching or friction elements at the adjoining ends of the base section and the closure section, which are designed to hold the closure section in the second position in a self-supporting manner.
- the hinge arrangement can accordingly also be designed to be self-supporting by means of a toothing that engages in different pivot positions or a friction fit.
- the closure section in the second position releasing the outlet recess can be rotated about the pivot axis (A) by an angle of 135 ° to 190 °, preferably between 150 ° and 170 °, compared to the first position.
- the closure section can preferably be oriented essentially vertically in the first position which closes the outlet recess. In commercially available containers, the closure section is mostly oriented vertically or parallel to the container side surface in the first position closing the outlet recess.
- the cover is rotated by a little less than 180 ° from this position closing the outlet recess into the defined open position so that, on the one hand, the outlet recess is reliably released and, on the other hand, it is still easy to reach behind the open cover ( it does not touch the side wall).
- the base section can be attached to the container such that it can be detached and fastened without tools. This enables a damaged cover to be replaced quickly. Since the complete device for locking the cover in the open position is part of the cover itself, this can also be easily replaced by replacing the cover.
- the base section can have a locking recess, in particular arranged on a side of the base section facing away from the hinge arrangement, which is designed and intended to be brought into engagement with a corresponding locking projection on the container near the outlet recess.
- a reverse arrangement of the locking projection and locking recess is just as possible.
- a snap connection can be provided for simple, tool-free clipping of the cover to the container.
- the base section can have a guide rib and the container can have a corresponding guide slot in the area of the outlet recess. In this way, the assembly of the cover on the container can be further simplified.
- both the base section and the closure section can have an essentially plate-shaped structure and can be connected to one another at the adjacent side edge by the hinge arrangement.
- Such a shape enables a simple tool design for the production of the cover.
- the closure body in the first position, which closes the outlet recess, can fit flush into the outer surface of the base and / or the side wall.
- a region of the outer surface of the container can preferably be adjacent to Be the outlet recess indented so that the, in particular plate-shaped, cover can be inserted / inserted into the indentation.
- Fig. 1 shows a perspective view of a container 1 according to a preferred embodiment of the present invention.
- the container 1 shown is a so-called intermediate bulk container.
- Containers of this type have a base 2, which mostly has a pallet-like sub-base structure, as well as a base from upwardly extending side wall 4.
- the container 1 shown also has a lid which is not referred to in any more detail here.
- the elements described above form an outer structure of the container 1, which shield an internal tank or bag (not shown) from external influences and also provide a stackability of identical containers 1.
- Such intermediate bulk containers enable the safe transport of liquid, viscous or free-flowing goods.
- the inner tank or bag is equipped on its underside or in a lower area with an outlet valve 8, which is in the Fig. 1 is not shown in detail.
- the container 1 has an outlet recess 6 in its outer structure, ie in its bottom 2 and / or its side wall 4, which has an opening through said outer structure or a mounting shaft for the Valve 8 represents.
- said outlet recess 6 is protected on the outside of the container by a cover 10.
- Fig. 2 shows a perspective detailed view of the outlet recess 6, which is arranged in the illustrated preferred embodiment in the container bottom 2 or in a bottom edge 3 formed by this.
- an exemplary valve arrangement 8 is also shown, which can be inserted into the outlet recess 6 from the inside of the container.
- the outlet recess 6 can be closed on the outside of the container with a cover 10.
- the one shown here Cover 10 is designed like a flap.
- the cover 10 has a base section 12, which is arranged in the direction of the top of the container in the example shown and with which the cover is fixed to the container 1 or to the bottom 2, as well as a closure section 16, which represents the structure closing the outlet recess 6.
- the closure section 16 is pivotably connected to the base section 12 via a hinge arrangement 14.
- the cover 10 fits into the outer surface of the base edge 3 in an essentially planar manner.
- an area of the outer surface of the bottom edge 3 immediately adjacent to the outlet recess 6 is indented opposite the remaining lateral outer surface, so that the cover 10 can be inserted into this indentation.
- a handle recess 5 is provided on the lower edge of the base 2, adjacent to the indentation into which the cover 10 is inserted.
- FIG. 4 Figure 10 shows cover 10 of FIG Fig. 3 in an open state.
- the closure section 16 is pivoted about a pivot axis A defined by the hinge arrangement 14.
- the illustrated cover 10 or its hinge arrangement 14 is designed according to the invention to be self-supporting, ie it locks itself automatically in a defined open position, as will be explained in more detail below.
- the defined open position in which the closure section 16 is locked is selected so that the opening is completely released, but the flap is not pivoted completely through 180 °, but an opening angle between 10 ° and 30 ° relative to the side surface of the container 1 remains. This has the advantage that the closure section 16 can be more easily grasped from behind for closing, since it does not rest against the side surface of the container 1.
- the Figures 5A to 5C show a side view of the cover 10 with a self-supporting closure body 16 according to a first embodiment.
- the hinge arrangement 14 is designed as a so-called bistable hinge or snap hinge.
- the hinge assembly 14 has a film hinge 15 which defines the fundamental pivot axis A of the closure section 16.
- the hinge arrangement 14 in this example has two prestressing or spring elements 18, which act here as tension spring elements, in order to bring about a snap action of the hinge 14.
- the spring element 18 is in a relaxed state in the closed state of the cover 10, in which the base section 12 and the closure section 16 are arranged essentially in alignment.
- the illustrated position of the closure section 16 forms a first rest position of the bistable hinge arrangement 14.
- two end points 19 thereof are at a distance r from one another.
- a first end point 19 of the spring element 18 is pivotably connected to the base section 12 via a film hinge and a second end point 19 of the spring element 18 is also pivotably connected to the closure section 16 via a film hinge. Since the spring element 18 is pivotably connected both to the base section 12 and to the closure section 16, it can track the pivoting movement of the closure section 16.
- Figure 5C shows this second rest position of the bistable hinge arrangement 14, which represents a defined open state of the cover 10.
- the distance between the two end points 19 of the spring element 18 in this second rest position again corresponds to the distance r, as in the first rest position.
- the hinge arrangement 14 according to the first exemplary embodiment causes the closure section 16 to automatically snap upwards after a predetermined deflection or when a predetermined pressure point is exceeded and is held or locked in this open position in a self-supporting manner by the spring force of the prestressing element 18.
- the bistable hinge is pretensioned in the closed position and can thus provide better tightness when closing.
- Fig. 6 shows the cover 10 with bistable hinge arrangement 14 according to a first exemplary embodiment in a cut-away illustration.
- Figure 7 shows a second, alternative embodiment for a cover 10 with a bistable hinge 15.
- the bistability or snap action of the film hinge 15 is generated in that a bend is introduced into the film hinge. Since the course of the film hinge 15 no longer coincides with the pivot axis A defined by it due to the introduction of the bend, the film hinge 15 functions per se in this embodiment as a resilient bending element that produces a snap action.
- Figure 8 shows a further alternative embodiment of the present invention in which the self-supporting cover is not realized by means of a bistable hinge but by means of complementary latching elements 28, 30 between the base section 12 and the closure section 16.
- the base section 12 has a type of toothing running in the circumferential direction of the hinge arrangement 14 coaxially to the pivot axis A, into which the locking projections 30 carried on resilient arms 29 engage.
- the geometry of the toothing 28 and the projections 30, together with the spring force of the arms 29, is set so that the hinge arrangement can easily be pivoted manually, but the holding force generated by the complementary latching elements 28, 30 is sufficient to keep the closure section 16 self-supporting .
- the cover 10 is equipped with a locking mechanism that can be detached and fastened without tools.
- the illustrated preferred embodiment of the cover 10 can be fastened to the container 1 in an uncomplicated manner via a snap mechanism. This is advantageous since the cover is a wear part of the container 1.
- Corresponding covers 10 are often damaged when handling containers 1 by means of floor conveyors such as forklifts, for example.
- a latching lug or a latching projection 20 is arranged above the outlet recess 6 on the outer surface of the indentation.
- This is adapted and provided to be brought into engagement with a corresponding latching recess 22 on the base section 12 of the cover 10.
- the latching recess 22 is located in an upper area of the base section 12 facing the inside of the container.
- a guide bevel 23 is formed, which enables it to slide over the also beveled latching lug 20, thus creating a snap action to create.
- a guide rib 24, which dips into a complementary groove or a guide slot 26 on the upper edge of the indentation above the outlet recess 6 in the container 1, ensures a guided assembly movement and a secure snap-in of the cover 10 during assembly on the container 1.

Description
Die vorliegende Erfindung betrifft einen Behälter zum Transport und zur Lagerung flüssiger, viskoser oder rieselfähiger Stoffe, insbesondere der Intermediate Bulk Container Bauart, mit einem Boden, einer Seitenwandung und zumindest einer Auslassausnehmung im Boden und/oder der Seitenwandung, in welcher ein Auslassventil angeordnet oder anordenbar ist und welche mittels einer Abdeckung behälterseitig verschließbar ist.The present invention relates to a container for the transport and storage of liquid, viscous or pourable substances, in particular of the intermediate bulk container type, with a base, a side wall and at least one outlet recess in the base and / or the side wall, in which an outlet valve is or can be arranged and which can be closed on the container side by means of a cover.
Sogenannte Großpackmittel bzw. Intermediate Bulk Container (IBC) werden zum Transport und zur Lagerung flüssiger und rieselfähiger Stoffe verwendet. Sie werden bspw. bei der Produktion von Chemikalien, Lebensmitteln, Kosmetik und Pharmazeutika eingesetzt. Solche Behälter weisen in der Regel ein Auslassventil in Bodennähe auf, welches in einer Auslassausnehmung bzw. einem VentilMontageschacht in der Außenwand des Behälters montiert ist und mittels welchem der fließ- oder rieselfähige Inhalt des Behälters entnommen werden kann.So-called intermediate bulk containers (IBC) are used for the transport and storage of liquid and pourable materials. They are used, for example, in the production of chemicals, food, cosmetics and pharmaceuticals. Such containers usually have an outlet valve near the bottom, which is mounted in an outlet recess or a valve assembly shaft in the outer wall of the container and by means of which the free-flowing or pourable contents of the container can be removed.
Es ist im Stand der Technik allgemein bekannt, bei solchen IBC eine Abdeckung in Form einer Klappe an der Außenseite der Auslassausnehmung (des Ventil-Montageschachts) vorzusehen. Mit einer solchen Abdeckung kann bis zu einem gewissen Grad eine Schutzwirkung bspw. gegen Staub bewerkstelligt werden. Die bekannten klappenartigen Abdeckungen können die Auslassausnehmung jedoch teilweise nicht vollständig abdecken, da sie nur lose vor dieser baumeln, was zu einer schlechten Staubdichtigkeit führt. Zudem muss der Anwender zum Erreichen der Auslassausnehmung bzw. des Auslassventils in derartigen bekannten Behältern die Abdeckung oftmals manuell in einer geöffneten Stellung halten, sodass nur eine Hand zum Bedienen, zur Montage des Ventils oder zum Anschließen eines Schlauchs an dieses verbleibt.It is generally known in the prior art to provide a cover in the form of a flap on the outside of the outlet recess (the valve assembly shaft) in such IBCs. With such a cover, a protective effect, for example against dust, can be achieved to a certain extent. The known flap-like covers can, however, in some cases not completely cover the outlet recess, since they only dangle loosely in front of it, which leads to poor dust tightness. In addition, in order to reach the outlet recess or the outlet valve in such known containers, the user must use the Often times, hold the cover manually in an open position so that only one hand remains to operate, assemble the valve or connect a hose to it.
Ein weiteres Problem, das im Zusammenhang mit den vorstehend beschriebenen Abdeckungen häufig auftritt, ist deren Beschädigung bei der Handhabung der Behälter mit Flurfördermitteln.Another problem that frequently occurs in connection with the covers described above is their damage when handling the containers with floor conveyors.
Einige Behälter aus dem Stand der Technik weisen Vorrichtungen auf, mittels welchen die Abdeckung im geöffneten Zustand am Behälter verrastet werden kann. Solche Lösungen sind jedoch unpraktisch, wenn die Abdeckung beschädigt wird, da dann oftmals sowohl die Arretierungsvorrichtung am Behälter als auch die Abdeckung ausgetauscht werden muss.Some containers from the prior art have devices by means of which the cover can be latched onto the container in the open state. However, such solutions are impractical if the cover is damaged, since then both the locking device on the container and the cover often have to be replaced.
Es existieren weitere Lösungen im Stand der Technik, bei denen die Abdeckung zum Erreichen des Auslassventils vollständig vom Behälter entfernt wird. Bei derartigen Behältern muss der Anwender nach der Installation des Ventils oder dem Durchführen eines Entleerungsvorgangs die Abdeckung auch manuell wieder auf die Auslassausnehmung aufsetzen, was die Anzahl benötigter Arbeitsschritte erhöht. Zudem muss die Abdeckung bei solchen Behältern im demontierten Zustand verstaut werden, damit sie nicht verloren geht.Other solutions exist in the prior art in which the cover is completely removed from the container to reach the outlet valve. In the case of such containers, after installing the valve or carrying out an emptying process, the user must also manually put the cover back on the outlet recess, which increases the number of work steps required. In addition, the cover of such containers must be stowed in the dismantled state so that it is not lost.
Es besteht also ein Bedarf nach einem Behälter zum Transport und zur Lagerung flüssiger, viskoser oder rieselfähiger Stoffe, insbesondere der Intermediate Bulk Container Bauart, der eine Abdeckung für eine Auslassausnehmung des Behälters mit verbesserter Handhabbarkeit bereitstellt, die vorteilhafter Weise zudem bei einem Defekt leicht austauschbar ist.There is therefore a need for a container for the transport and storage of liquid, viscous or free-flowing substances, in particular of the intermediate bulk container type, which provides a cover for an outlet recess of the container with improved manageability, which is also advantageously easy to replace in the event of a defect .
Die vorstehend beschriebenen Aufgaben werden durch einen Behälter gemäß dem unabhängigen Patentanspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The objects described above are achieved by a container according to
Grundsätzlich hat ein erfindungsgemäßer Behälter zum Transport und zur Lagerung flüssiger, viskoser oder rieselfähiger Stoffe einen Boden, eine Seitenwandung und zumindest eine Auslassausnehmung im Boden und/oder der Seitenwandung, in welcher ein Auslassventil angeordnet oder anordenbar ist. Die Auslassausnehmung ist mittels einer Abdeckung behälteraußenseitig verschließbar. Die Auslassausnehmung hat einen Basisabschnitt und einen Verschlussabschnitt. Der Basisabschnitt ist dazu ausgebildet, am Behälter befestigt oder befestigbar zu sein. Der Verschlussabschnitt ist dazu ausgebildet, die Auslassausnehmung verschließen zu können.In principle, a container according to the invention for the transport and storage of liquid, viscous or free-flowing substances has a base, a side wall and at least one outlet recess in the base and / or the side wall, in which an outlet valve is or can be arranged. The outlet recess can be closed on the outside of the container by means of a cover. The outlet recess has a base portion and a closure portion. The base section is designed to be attached or attachable to the container. The closure section is designed to be able to close the outlet recess.
Der Verschlussabschnitt ist über eine Scharnieranordnung um eine Drehachse schwenkbar am Basisabschnitt angelenkt, sodass der Verschlussabschnitt von einer ersten, die Auslassausnehmung verschließenden Stellung, in eine zweite, die Auslassausnehmung freigebende Stellung überführbar ist. Die Scharnieranordnung ist dazu ausgebildet ist, den Verschlussabschnitt in der zweiten, die Auslassausnehmung freigebenden Stellung selbsttragend zu halten oder zu arretieren. In anderen Worten ist eine schwenkbare Abdeckung/Klappe für eine Auslassausnehmung eines Behälters so ausgebildet, dass ihre Scharnieranordnung den Verschlussabschnitt bzw. die Klappe der Abdeckung in der geöffneten Stellung arretiert/sichert. Wenn die Abdeckung nach oben (entgegen der Schwerkraft) geöffnet wird, ist die Haltekraft der Arretierung zudem zumindest so stark ausgelegt, dass sie den Verschlussabschnitt entgegen der Schwerkraft selbsttragend halten kann.The closure section is articulated on the base section so that it can pivot about a rotation axis via a hinge arrangement, so that the closure section can be transferred from a first position, which closes the outlet recess, into a second position, which releases the outlet recess. The hinge arrangement is designed to hold or lock the closure section in a self-supporting manner in the second position releasing the outlet recess. In other words, a pivotable cover / flap for an outlet recess of a container is designed in such a way that its hinge arrangement locks / secures the closure section or the flap of the cover in the open position. When the cover is opened upwards (against the force of gravity), the holding force of the lock is also designed to be at least so strong that it can hold the closure section in a self-supporting manner against the force of gravity.
Der erfindungsgemäße Behälter hat den Vorteil, dass die Abdeckung zuverlässig in einer geöffneten Position gehalten werden kann, wenn die Auslassausnehmung oder das Auslassventil erreicht werden müssen. Dadurch hat der Anwender beide Hände für Montage- oder Bedientätigkeiten am Ventil frei und es wird zudem ein versehentliches Verschließen der Abdeckung während eines Montagevorgangs vermieden. Die Arretierung in der geöffneten Stellung wird gemäß der Erfindung durch die Scharnieranordnung der Abdeckung per se bewerkstelligt. Dies hat den Vorteil, dass der gesamte Arretierungsmechanismus Teil der Abdeckung ist und bei einem Defekt in einfacher Weise gemeinsam mit der Abdeckung ausgetauscht werden kann.The container according to the invention has the advantage that the cover can be reliably held in an open position when the outlet recess or the outlet valve have to be reached. As a result, the user has both hands free for assembly or operating activities on the valve and in addition, accidental closing of the cover during an assembly process is avoided. The locking in the open position is achieved according to the invention by the hinge arrangement of the cover per se. This has the advantage that the entire locking mechanism is part of the cover and can be easily replaced together with the cover in the event of a defect.
Bevorzugt kann es sich bei dem Behälter um einen Großladungsträger der Intermediate Bulk Container Bauart handeln, der einen internen Tank mit einem Auslassventil aufweist, welcher in einer äußeren Tragstruktur aus Boden und Seitenwandung beherbergt wird.The container can preferably be a large load carrier of the intermediate bulk container type, which has an internal tank with a Has outlet valve, which is housed in an outer support structure made of bottom and side wall.
Gemäß einer bevorzugten Ausführungsform kann die Scharnieranordnung ein Vorspann- oder Federelement aufweisen, das dazu ausgebildet ist, den Verschlussköper in der zweiten, geöffneten Stellung zu halten. Eine solche Ausgestaltung der Erfindung hat den Vorteil, dass unter der Vorspannungsbeaufschlagung die Abdeckung automatisch in eine definierte, geöffnete Position überführt werden kann, d.h. selbst wenn ein Anwender die Abdeckung manuell nicht vollständig öffnet, schnappt die Abdeckung von selbst in eine vollständig geöffnete Stellung.According to a preferred embodiment, the hinge arrangement can have a pretensioning or spring element which is designed to hold the closure body in the second, open position. Such an embodiment of the invention has the advantage that the cover can be automatically transferred into a defined, open position under the application of pretension, i.e. even if a user does not fully open the cover manually, the cover will snap to a fully open position by itself.
Gemäß einem bevorzugten Aspekt der Erfindung kann die Scharnieranordnung als bistabiles Scharnier ausgebildet sein, das je nach seiner relativen Lage bezüglich eines Druckpunktes entweder in die erste, die Auslassausnehmung verschließende Stellung, oder in die zweite, die Auslassausnehmung freigebende, Stellung vorgespannt ist. In anderen Worten kann das Scharnier der Abdeckung als sogenanntes Schnappscharnier ausgestaltet sein, dass es entweder in eine definierte verschlossene oder eine definierte geöffnete Stellung geschnappt ist, je nach relativer Lage des Verschlussabschnittes relativ zu einem Druckpunkt. Eine solche Ausführungsform hat den Vorteil, dass sich die Abdeckung immer entweder in einer komplett geschlossenen oder in einer definiert geöffneten Stellung befindet, wodurch Bedienfehler, wie bspw. ein unvollständiges Verschließen der Abdeckung vermieden werden.According to a preferred aspect of the invention, the hinge arrangement can be designed as a bistable hinge which, depending on its relative position with respect to a pressure point, is pretensioned either in the first position closing the outlet recess or in the second position releasing the outlet recess. In other words, the hinge of the cover can be designed as a so-called snap hinge that it is either snapped into a defined closed position or a defined open position, depending on the relative position of the closure section relative to a pressure point. Such an embodiment has the advantage that the cover is always either in a completely closed position or in a defined open position, as a result of which operating errors such as incomplete closing of the cover are avoided.
Gemäß einem bevorzugten Aspekt der Erfindung kann die Abdeckung stoffeinstückig als Kunststoffbauteil, insbesondere aus einem thermoplastischen Werkstoff, gefertigt sein. Dies ermöglicht es, die Abdeckung als einfach zu fertigendes und günstig herzustellendes Austauschteil auszulegen. Gemäß einer weiter bevorzugten Ausführungsform kann das bistabile Scharnier als eine Filmscharnieranordnung ausgebildet sein. Die Umsetzung des Scharniers als Filmscharnier unterstützt die Auslegung der Abdeckung als einfaches, einstückig zu fertigendes Austauschteil. Bevorzugt kann die Abdeckung in einem Stück als Spritzgussteil gefertigt sein.According to a preferred aspect of the invention, the cover can be manufactured in one piece as a plastic component, in particular from a thermoplastic material. This makes it possible to design the cover as a replacement part that is easy to manufacture and inexpensive to manufacture. According to a further preferred embodiment, the bistable hinge can be designed as a film hinge arrangement. The implementation of the hinge as a film hinge supports the design of the cover as a simple, one-piece replacement part. The cover can preferably be manufactured in one piece as an injection molded part.
Gemäß einem bevorzugten Aspekt der Erfindung kann das bistabile Scharnier als ein gekrümmtes Filmscharnier ausgeführt sein. Durch einbringen einer Krümmung bzw. Wölbung in das Filmscharnier kann auf einfache Weise Spannung in das Scharnier gebracht und eine Schnappwirkung erzeugt werden. Das Filmscharnier bildet in einem solchen Fall per se das Vorspann- oder Federelement aus, das den Verschlusskörper in der zweiten, geöffneten Stellung vorspannt/hält.According to a preferred aspect of the invention, the bistable hinge can be designed as a curved film hinge. By introducing a curvature or curvature in the film hinge, tension can be brought into the hinge in a simple manner and a snap effect can be generated. In such a case, the film hinge per se forms the prestressing or spring element which prestresses / holds the closure body in the second, open position.
Gemäß einer bevorzugten Ausführungsform kann das bistabile Scharnier als Vorspann- oder Federelement ein federndes, eine Schnappwirkung erzeugendes Biegeelement oder Zugelement aufweisen.According to a preferred embodiment, the bistable hinge can have a resilient bending element or tension element producing a snap action as a pretensioning or spring element.
Gemäß einem bevorzugten Aspekt der Erfindung kann die Scharnieranordnung komplementäre Rast- oder Reibelemente an den angrenzenden Enden des Basisabschnitts und des Verschlussabschnitts aufweisen, die dazu ausgebildet sind, den Verschlussabschnitt selbsttragend in der zweiten Stellung zu halten. Als Alternative zu einer Ausführungsform mit Vorspannelementen kann die Scharnieranordnung demnach auch durch eine in verschiedenen Schwenkpositionen einrastende Verzahnung oder einen Reibschluss selbstragend ausgelegt sein.According to a preferred aspect of the invention, the hinge arrangement can have complementary latching or friction elements at the adjoining ends of the base section and the closure section, which are designed to hold the closure section in the second position in a self-supporting manner. As an alternative to an embodiment with pretensioning elements, the hinge arrangement can accordingly also be designed to be self-supporting by means of a toothing that engages in different pivot positions or a friction fit.
Gemäß einer bevorzugten Ausführungsform kann der Verschlussabschnitt in der zweiten, die Auslassausnehmung freigebenden, Stellung um einen Winkel von 135° bis 190°, bevorzugt zwischen 150° und 170°, gegenüber der ersten Stellung um die Schwenkachse (A) rotiert sein. Bevorzugt kann der Verschlussabschnitt in der ersten, die Auslassausnehmung verschließenden Stellung im Wesentlichen vertikal ausgerichtet sein. In handelsüblichen Behältern ist der Verschlussabschnitt in der ersten, die Auslassausnehmung verschließenden Stellung zumeist vertikal bzw. parallel zur Behälterseitenfläche ausgerichtet. Es ist von Vorteil, wenn die Abdeckung um etwas weniger als 180° aus dieser die Auslassausnehmung verschließenden Stellung in die definierte geöffnete Stellung rotiert wird, sodass zum einen die Auslassausnehmung zuverlässig freigegeben wird, zum anderen aber ein Hintergreifen der geöffneten Abdeckung noch einfach möglich ist (diese nicht an der Seitenwand anliegt).According to a preferred embodiment, the closure section in the second position releasing the outlet recess can be rotated about the pivot axis (A) by an angle of 135 ° to 190 °, preferably between 150 ° and 170 °, compared to the first position. The closure section can preferably be oriented essentially vertically in the first position which closes the outlet recess. In commercially available containers, the closure section is mostly oriented vertically or parallel to the container side surface in the first position closing the outlet recess. It is advantageous if the cover is rotated by a little less than 180 ° from this position closing the outlet recess into the defined open position so that, on the one hand, the outlet recess is reliably released and, on the other hand, it is still easy to reach behind the open cover ( it does not touch the side wall).
Gemäß einer bevorzugten Ausführungsform kann der Basisabschnitt werkzeuglos lösbar und befestigbar am Behälter angebracht sein. Dies ermöglicht einen schnellen Austausch einer beschädigten Abdeckung. Da die komplette Vorrichtung zum Arretieren der Abdeckung in der geöffneten Stellung Teil der Abdeckung selbst ist, kann auch diese auf einfache Weise durch Austausch der Abdeckung erneuert werden.According to a preferred embodiment, the base section can be attached to the container such that it can be detached and fastened without tools. This enables a damaged cover to be replaced quickly. Since the complete device for locking the cover in the open position is part of the cover itself, this can also be easily replaced by replacing the cover.
Gemäß einem bevorzugten Aspekt der Erfindung kann der Basisabschnitt eine, insbesondere an einer von der Scharnieranordnung abgewandten Seite des Basisabschnitts angeordnete, Rastausnehmung aufweisen, der dazu ausgebildet und vorgesehen ist, mit einem korrespondierenden Rastvorsprung am Behälter nahe der Auslassausnehmung in Eingriff gebracht zu werden. Eine umgekehrte Anordnung von Rastvorsprung und Rastausnehmung ist ebensogut möglich. In anderen Worten kann eine Schnappverbindung zum einfachen, werkzeuglosen Festclipsen der Abdeckung am Behälter vorgesehen sein.According to a preferred aspect of the invention, the base section can have a locking recess, in particular arranged on a side of the base section facing away from the hinge arrangement, which is designed and intended to be brought into engagement with a corresponding locking projection on the container near the outlet recess. A reverse arrangement of the locking projection and locking recess is just as possible. In other words, a snap connection can be provided for simple, tool-free clipping of the cover to the container.
Gemäß einer bevorzugten Ausführungsform kann der Basisabschnitt eine Führungsrippe aufweisen und der Behälter kann im Bereich der Auslassausnehmung einen korrespondierenden Führungsschlitz aufweisen. Auf diese Weise kann die Montage der Abdeckung am Behälter weiter vereinfacht werden.According to a preferred embodiment, the base section can have a guide rib and the container can have a corresponding guide slot in the area of the outlet recess. In this way, the assembly of the cover on the container can be further simplified.
Gemäß einer bevorzugten Ausführungsform können sowohl der Basisabschnitt als auch der Verschlussabschnitt eine im Wesentlichen plattenförmige Struktur aufweisen und an angrenzenden Seitenkante durch die Scharnieranordnung miteinander verbunden sein. Eine solche Formgebung ermöglicht eine einfache Werkzeuggestaltung für die Fertigung der Abdeckung.According to a preferred embodiment, both the base section and the closure section can have an essentially plate-shaped structure and can be connected to one another at the adjacent side edge by the hinge arrangement. Such a shape enables a simple tool design for the production of the cover.
Gemäß einem bevorzugten Aspekt der Erfindung kann der Verschlusskörper in der ersten, die Auslassausnehmung verschließenden Stellung sich bündig in die Außenfläche des Bodens und/oder der Seitenwandung einfügen. Eine solche Auslegung des Behälters und der Abdeckung vermeidet eine Beschädigung der letzteren, da keine Kante der Abdeckung im verschlossenen Zustand aus der Behälterseitenfläche herausragt, an der man hängenbleiben könnte. Zu diesem Zweck kann bevorzugt ein Bereich der Außenfläche des Behälters angrenzend zur Auslassausnehmung eingerückt sein, sodass die, insbesondere plattenförmige, Abdeckung in die Einrückung eingesetzt/eingefügt werden kann.According to a preferred aspect of the invention, in the first position, which closes the outlet recess, the closure body can fit flush into the outer surface of the base and / or the side wall. Such a design of the container and the cover avoids damage to the latter, since no edge of the cover in the closed state protrudes from the container side surface on which one could get caught. For this purpose, a region of the outer surface of the container can preferably be adjacent to Be the outlet recess indented so that the, in particular plate-shaped, cover can be inserted / inserted into the indentation.
