Description

Die Erfindung betrifft einen Massengutbehälter mit Deckel, vorzugsweise zur Verwendung als Einweg-Transportgefäß für Gift und/oder Krankenhausmüll.The invention relates to a bulk container with a lid, preferably for use as a disposable transport container for poison and / or hospital waste.

Als Einweg-Transportgefäß sind Aufnahmebehälter unterschiedlichster Bauart und aus den verschiedensten Materialien bekannt. So ist es beispielsweise bekannt, Waschpulver oder dgl. in Pappzylindern zu lagern. Solche Pappzylinder sind umweltfreundlich aber teuer in der Herstellung und gegenüber Feuchtigkeit äußerst empfindlich und deshalb für Flüssigkeiten oder zur Aufbewahrung in nicht ganz trockenen Räumen ungeeignet.Receptacles of various designs and made from a wide variety of materials are known as disposable transport containers. For example, it is known to store washing powder or the like in cardboard cylinders. Such cardboard cylinders are environmentally friendly but expensive to manufacture and extremely sensitive to moisture and therefore unsuitable for liquids or for storage in rooms that are not completely dry.

Zur Aufnahme von Flüssigkeiten ist es deshalb üblich, gespritzte Kunststoffeimer zu verwenden, die jedoch in der Herstellung relativ teuer sind. Weiter ist es bekannt, Müllsäcke aus Papier oder Kunststoff zu verwenden. Solche Müllsäcke sind im ungebrauchten Zustand platzsparend zu lagern und preiswert in der Herstellung. Sie sind jedoch äußerst empfindlich gegenüber scharfkantigem Müll.It is therefore common to use sprayed plastic buckets to hold liquids, but these are relatively expensive to manufacture. It is also known to use garbage bags made of paper or plastic. Such garbage bags are space-saving when unused and inexpensive to manufacture. However, they are extremely sensitive to sharp-edged garbage.

Für Sondermüll, z. B. für medizinischen Müll, wie er in Krankenhäusern, bei Ärzten oder in Labors anfällt, ist es durch die DE-A-22 33 435 bekannt, diesen Müll gesondert, z. B. in Müllsäcken oder im Inneren wasserdicht kaschierter Pappzylinder zu sammeln, diese dann zu verschließen und der Müllverbrennung zuzuführen. Die bekannten Behälter haben den Nachteil, daß sie nicht mit Sicherheit das Austreten von Flüssigkeit, wie z. B. Blut oder dgl., verhindern können. Zum anderen besteht auch die Gefahr, daß spitze oder scharfe Gegenstände im Müll, wie Wegwerfspritzen oder dgl., die Wände durchstoßen, so daß eine Verletzungsgefahr für die handhabenden Personen besteht.For hazardous waste, e.g. B. for medical waste, as it is obtained in hospitals, doctors or in laboratories, it is known from DE-A-22 33 435 to separate this waste, eg. B. in garbage bags or inside waterproof laminated cardboard cylinders, then to seal them and to incinerate them. The known containers have the disadvantage that they do not ensure the escape of liquid, such as. B. can prevent blood or the like. On the other hand, there is also the risk that pointed or sharp objects in the garbage, such as disposable syringes or the like, pierce the walls, so that there is a risk of injury to the handling personnel.

Aus diesem Grunde werden in Krankenhäusern häufig die im Haushalt üblichen großvolumigen, gespritzten Kunststoffeimer eingesetzt, die, wie bereits erwähnt, vergleichsweise teuer sind, andererseits ist eine Entleerung derartiger Eimer zum Mehrfachgebrauch und anschließende Reinigung und Desinfektion mit noch erheblicheren Kosten verbunden.For this reason, the usual large-volume, sprayed plastic buckets are used in hospitals, which, as already mentioned, are comparatively expensive, on the other hand, emptying such buckets for multiple use and subsequent cleaning and disinfection is associated with even more significant costs.

Aufgabe der Erfindung ist es deshalb, einen zuverlässigen Verpackungs- und Transportbehälter zu schaffen, der platzsparend zu lagern, umweltfreundlich, billig, gut transportabel, luftdicht zu verschließen und sicher sowohl gegen Flüssigkeiten als auch gegenüber scharfkantigem Müll ist.The object of the invention is therefore to provide a reliable packaging and transport container that is space-saving, environmentally friendly, cheap, easy to transport, airtight and secure both against liquids and against sharp-edged garbage.

Diese Aufgabe der Erfindung wird bei dem Massengutbehälter der eingangs bezeichneten Art dadurch gelöst, daß der die Behälteröffnung begrenzende Handhabungs- und Versteifungsrand in seinen Außenabmessungen den Außenabmessungen der vorgeschnittenen Ausgangsfolie für einen Vakuumziehvorgang entspricht, und das Materialstärkenverhältnis zwischen dem Versteifungsrand und dem gezogenen Teil wenigstens 4,5 : 1 beträgt.This object of the invention is achieved in the bulk container of the type described in the introduction in that the outer edge of the handling and stiffening edge corresponds to the outer dimensions of the pre-cut starting film for a vacuum-drawing process, and the material thickness ratio between the stiffening edge and the drawn part is at least 4. Is 5: 1.

Durch die Gestaltung eines derartigen Behälters aus vakuumgezogenem Folienmaterial wird zum einen erreicht, daß der Behälter vergleichsweise wirtschaftlich herzustellen und daher als Wegwerfartikel verwendbar ist, zum anderen gewährleisten derartige Folienmaterialien Flüssigkeitsdichtheit und eine entsprechend hohe Steifigkeit bei geeigneter Formgebung, so daß die Behälter sowohl leer, als auch gefüllt stapelbar sind.The design of such a container made of vacuum-drawn film material ensures, on the one hand, that the container is comparatively economical to manufacture and can therefore be used as a disposable article, and on the other hand, such film materials ensure liquid tightness and a correspondingly high rigidity with suitable shaping, so that the containers are both empty and are also stackable when filled.

Grundsätzlich sind tiefgezogene Behälter, beispielsweise zur Aufnahme von zum alsbaldigen Verbrauch bestimmter Lebensmitteln, wie Quark, Joghurt oder dgl., bekannt. Die bekannten Behälter sind jedoch von ihrem statischen Aufbau her zum sicheren Transport größerer Mengen luftdicht abgeschlossenen Mülls nicht geeignet. Die Massengutbehälter nach der Erfindung sind vorzugsweise für Aufnahmevolumen über 25 Liter ausgelegt.Basically, deep-drawn containers are known, for example for holding certain foods, such as curd cheese, yoghurt or the like, which are intended for immediate consumption. However, the known structure of the known containers is not suitable for the safe transportation of large amounts of airtight waste. The bulk containers according to the invention are preferably designed for receiving volumes over 25 liters.

Nach einem weiteren Merkmal der Erfindung ist es vorgesehen, daß zur weiteren Verstärkung in die Gefäßwände Versteifungsrippen eingezogen sind und der Behälterboden nach innen gewölbt ist.According to a further feature of the invention it is provided that for further reinforcement stiffening ribs are drawn into the vessel walls and the container bottom is curved inwards.

Es hat sich als zweckmäßig erwiesen, wenn der Behälter im wesentlichen als viereckiger Kasten mit vom Rand- zum Bodenbereich hin konisch verlaufenden Behälterwänden ausgebildet ist. Diese Formgebung hat zum einen den Vorteil, daß sich durch die konischen Wandflächen, wie bei derartigen vakuumgezogenen Kleinstbehältern bekannt, im leeren Zustand eine hohe Stapelfähigkeit ergibt, so daß bei der Lagerhaltung ein sehr geringer Raum benötigt wird, zum anderen können die gefüllten Behälter in rechteckiger Form auf der Ladefläche eines Transportfahrzeuges günstiger und dichter aufgestellt werden. Die gute Stapelbarkeit der leeren Behälter wird noch durch in die Gefäßwände eingezogene Sicken erhöht, die ein Festsaugen der ineinander gestapelten leeren Behälter verhindern.It has proven to be expedient if the container is essentially designed as a square box with container walls that run conically from the edge to the bottom region. This shape has the advantage that the conical wall surfaces, as is known for such vacuum-drawn small containers, provide high stackability when empty, so that very little space is required for storage, and on the other hand the filled containers can be rectangular Form on the loading surface of a transport vehicle cheaper and denser. The good stackability of the empty containers is further increased by beads drawn into the vessel walls, which prevent the empty containers stacked one inside the other from being sucked up.

Die Stapelbarkeit der gefüllten Behälter wird besonders durch die erfindungsgemäße Form des Deckels sichergestellt. Die nach innen gerichteten Schrägen des Deckels wirken formschlüssig mit den Abschrägungen des Behälters zusammen und vermeiden dadurch, daß Querkräfte auf die zwischen Behälter und Deckel angeordnete Klebefolie wirken. Der aufgesetzte Deckel ergibt somit eine sichere Standfläche für den nachfolgenden Behälter. Durch die im Deckel angeordnete, nach oben gerichtete Stapelwulst werden die übereinander gestapelten Behälter sicher in ihrer Lage fixiert. Diese Fixierung wird außerdem durch die nach oben gerichtete Deckelwölbung, die von unten in die Bodenwölbung des nachfolgenden Behälters greift, unterstützt.The stackability of the filled containers is ensured in particular by the shape of the lid according to the invention. The inward bevels of the lid interact positively with the bevels of the container and thereby avoid that transverse forces act on the adhesive film arranged between the container and the lid. The attached lid thus provides a safe footprint for the subsequent container. Due to the stacking bead arranged in the lid and pointing upwards, the stacked containers are securely fixed in their position. This fixation is also supported by the upward curvature of the lid which engages from below in the curvature of the bottom of the subsequent container.

Nach einem weiteren Merkmal der Erfindung ist diese stapelwulst als umlaufender, definierter Rißverschluß ausgeführt. Diese Ausgestaltung ist besonders dann vorteilhaft, wenn der Behälterdeckel mit Hilfe einer Folienschweißmaschine unlösbar auf dem Aufnahmegefäß be- fes;igt ist.According to a further feature of the invention, this stacked bead is designed as a circumferential, defined tear fastener. This configuration is This is particularly advantageous when the container lid is attached to the receptacle in a non-detachable manner using a film welding machine.

Diese Ausführung eignet sich auch besonders für Pulvergüter wie Waschpulver und dgl. Der Deckel kann jedoch auch mit einem Schnappverschluß versehen werden. In diesem Falle weist der Deckelrand Ansätze oder Einziehungen auf, die elastisch über den Versteifungsrand des Aufnahmegefäßes greifen.This version is also particularly suitable for powder goods such as washing powder and the like. However, the lid can also be provided with a snap lock. In this case, the edge of the lid has projections or indentations which grip elastically over the stiffening edge of the receptacle.

In besonderer Ausgestaltung sieht die Erfindung vor, daß Behälter und Deckel einstückig aus dem vakuumgezogenen Material ausgebildet sind. In diesem Fall ist zwischen dem Versteifungsrand des Aufnahmegefäßes und dem Deckelrand eine definierte Knickkante vorgesehen. Der Preis solcher Behälter ist marktentscheidend. Die Summe der Kosteneinsparungen aus reduzierten Hand- und Maschinenzeiten sowie Materialgewicht und Abfallvermeidung ergeben mit der Erfindung optimale Werte. Weitere Vorteile, Einzelheiten und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung sowie anhand der Zeichnungen.In a special embodiment, the invention provides that the container and lid are made in one piece from the vacuum-drawn material. In this case, a defined crease edge is provided between the stiffening edge of the receptacle and the lid edge. The price of such containers is decisive for the market. The sum of the cost savings from reduced manual and machine times as well as material weight and waste avoidance result in optimal values with the invention. Further advantages, details and features of the invention result from the following description and from the drawings.

Der Massengutbehälter ist im allgemeinen mit 1 bezeichnet. Er besteht aus einem Aufnahmegefäß 3 und einem Deckel 13. Das Aufnahmegefäß 3 weist einen handhabungs- und Versteifungsrand 2 auf, dessen Stärke wenigstens das, 4,5-fache der Stärke der Gefäßwände 4 beträgt. Auf dem Versteifungsrand 2 ist eine Klebefolie 10 angebracht, die durch einen Schutzfilm 11 abgedeckt ist. Klebefolie und Schutzfilm sind vorzugsweise einstückig ausgeführt und weisen an den Ecken 12 des Aufnahmegefäßes 3 Einschnitte auf, die sich wenigstens über Teile ihrer Breite erstrecken. Der obere Teil der nach unten konisch zulaufenden Gefäßwände 4 ist als Abschrägung 7 ausgeführt. Die Abschrägungen 7 dienen als Zentrier- und Anlageflächen für entsprechende Schrägen 15 des Deckels 13. Da die Gefäßwände 4 eine verhältnismäßig geringe Stärke haben, sind aus Festigungsgründen Versteifungsrippen 5 vorgesehen. Außerdem sind in die Gefäßwände Sicken 6 eingezogen, die ein Festsaugen der ineinander gestapelten, leeren Transportgefäße verhindern. Durch eine nach innen gerichtete Versteifungs- und Stapelwölbung 9 ist der Gefäßboden 8 zusätzlich ausgesteift.The bulk container is generally designated 1. It consists of a receptacle 3 and a lid 13. The receptacle 3 has a handling and stiffening edge 2, the thickness of which is at least 4.5 times the thickness of the vessel walls 4. On the stiffening edge 2, an adhesive film 10 is attached, which is covered by a protective film 11. Adhesive film and protective film are preferably made in one piece and have 3 incisions at the corners 12 of the receptacle which extend at least over part of their width. The upper part of the tapered vessel walls 4 is designed as a bevel 7. The bevels 7 serve as centering and contact surfaces for corresponding bevels 15 of the lid 13. Since the vessel walls 4 have a relatively small thickness, stiffening ribs 5 are provided for reasons of strengthening. In addition, beads 6 have been drawn into the vessel walls, which prevent the stacked, empty transport vessels from being sucked into place. The vessel base 8 is additionally stiffened by an inward stiffening and stacking curvature 9.

Das Aufnahmegefäß 3 kann mit dem Deckel 13 luftdicht verschlossen werden. Der Deckel weist deshalb ebenfalls einen Rand 14 auf, der in seinen Abmessungen dem Versteifungsrand 2 des Aufnahmegefäßes entspricht. Der stabil ausgeführte Deckelrand 14 wird, nach Entfernen des Schutzfilmes 11, auf die Klebefolie 10 gedrückt und schließt das Aufnahmegefäße 3 luftdicht ab. Um diesen Klebeverschluß von Querbeanspruchungen freizuhalten, sind in den Deckel 13 Schrägen 15 eingeformt, die, wie beschrieben, mit den Abschrägungen 7 des Aufnahmegefäßes 3 zusammenwirken. Der Deckel 13 weist weiter eine Stapelwulst 16 auf, deren Ausmaße auf die Außenkonturen des Gefäßbodens abgestimmt sind. Durch diese Stapelwulst 16 wird folglich ein Verrutschen der aufeinander gestapelten, gefüllten Behälter verhindert. Die nach oben gerichtete Versteifungs- und Stapelwölbung 19 des Deckels 13, die beim Stapeln in die Versteifungs- und Stapelwölbung 9 des darüber stehenden Aufnahmegefäßes greift, ergibt zusätzliche Standsicherheit.The receptacle 3 can be closed airtight with the lid 13. The lid therefore also has an edge 14, the dimensions of which correspond to the stiffening edge 2 of the receptacle. After the protective film 11 has been removed, the sturdy lid rim 14 is pressed onto the adhesive film 10 and closes the receptacles 3 in an airtight manner. In order to keep this adhesive closure free from transverse stresses, bevels 15 are formed in the cover 13, which, as described, interact with the bevels 7 of the receptacle 3. The lid 13 also has a stacking bead 16, the dimensions of which are matched to the outer contours of the vessel bottom. This stacking bead 16 consequently prevents the filled containers stacked on one another from slipping. The upward stiffening and stacking curvature 19 of the lid 13, which engages in the stiffening and stacking curvature 9 of the receptacle above it when stacked, provides additional stability.

Obwohl der beschriebene eigensteife Behälter vorzugsweise für Sondermüll, wie er z. B. in Krankenhäusern oder dgl. anfällt, konzipiert ist, eignet er sich gleichwohl hervorragend als Einweg-Transportgefäß.Although the self-rigid container described is preferably for hazardous waste, such as. B. in hospitals or the like. Is designed, it is nevertheless ideal as a disposable transport container.

So kann z. B. der Deckel 13 mit dem Aufnahmegefäß 3 mittels eines Folienschweißgerätes oder dgl. nach Einfüllen des Transportmediums unlösbar verschlossen werden. Zum Öffnen des Behälters ist dann ein Rißverschluß 17 vorgesehen, der in die Stapelwulst 16 eingeformt ist. Zu diesem Zweck ist die Stapelwulst 16 als Doppelwulst 21 ausgebildet, zwischen deren beiden aufragenden Wülsten 22 eine geringer gedehnte, streifenförmige Zone 23 stärkeren Materials verbleibt. Die streifenförmige Zone 23 kann leicht aus dem Deckel 13 gerissen werden, so daß das Aufnahmegefäß 3 zugängig wird. Neben Klebefolie oder Rißverschluß sind weitere Verschlußarten möglich. So kann der Deckelrand 14 mit Ansätzen oder Einziehungen 18 versehen werden, die über den Versteifungsrand 2 des Aufnahmegefäßes 3 greifen und einen beliebig zu öffnenden Schnappverschluß ergeben.So z. B. the lid 13 with the receptacle 3 by means of a film welder or the like. After filling the transport medium are closed non-detachably. To open the container, a tear seal 17 is then provided, which is molded into the stacking bead 16. For this purpose, the stacking bead 16 is designed as a double bead 21, between the two protruding beads 22 of which a less stretched, strip-shaped zone 23 of thicker material remains. The strip-shaped zone 23 can easily be torn from the lid 13 so that the receptacle 3 is accessible. In addition to adhesive film or a zipper, other types of closures are possible. Thus, the lid edge 14 can be provided with projections or recesses 18 which reach over the stiffening edge 2 of the receptacle 3 and result in a snap closure which can be opened as desired.

Obwohl der erfindungsgemäße eigensteife Behälter vorzugsweise zweiteilig ausgeführt ist, d. h. aus einem Aufnahmegefäß 3 und einem separaten Deckel 13 besteht, ist es grundsätzlich möglich, den Behälter einteilig herzustellen. Bei dieser Ausführungsform ist zwischen dem Transportrand 2 des Aufnahmegefäßes und dem Deckelrand 14 eine Knickkante 20 vorgesehen, die vorzugsweise als gezogene Nut 24 ausgebildet ist.Although the inherently rigid container according to the invention is preferably designed in two parts, i. H. consists of a receptacle 3 and a separate lid 13, it is fundamentally possible to manufacture the container in one piece. In this embodiment, a folded edge 20 is provided between the transport edge 2 of the receptacle and the lid edge 14, which is preferably designed as a drawn groove 24.
