Definitions
- the invention relates to a container for hazardous waste and dangerous goods transport with an outer container, which has a circumferential sealing edge at its container opening and can be securely closed by a lid by means of closing devices, and with an interchangeable film inner container arranged in the outer container.
- Containers of this type are used to transport hazardous waste and hazardous goods, which can be present, for example, in dusty, free-flowing, pasty or liquid form and often also as a mixture thereof.
- Essential requirements for such containers are therefore that the conveyed material is prevented from escaping from the container under the loads occurring during transport.
- previously known containers are used for this purpose in the outer container, which is usually made of steel, as a film inner container, which is bound.
- the foil bags are hooked onto the outside of the outer container for filling and are often perforated.
- the goods to be transported can partially escape after the film bag has been closed and lead to contamination of the outer container, in particular also the inner surface of the lid and the sealing surfaces. For one thing this requires a considerable cleaning effort for the outer container and the lid. On the other hand, strongly adhesive residues cannot always be completely removed. This leads to the fact that the next inserted film bag sticks to these points and is torn either during filling or during the movements occurring during transport, which in turn can lead to severe contamination of the outer container and the lid.
- Contamination in the seal area, particularly on the seals inserted on the cover, is particularly problematic because damage to the seal can occur during cleaning. In practice, this means that these seals have to be replaced frequently, or the containers remain permanently leaky.
- the required complex cleaning of the outer container and the lid makes it necessary to provide complex cleaning systems and to use larger amounts of cleaning agents and detergents.
- the cleaning process itself is associated with a considerable amount of work and, in the case of harmful and / or hazardous waste, can lead to damage to the health of the working personnel and to damage to the original.
- the cleaning agents and detergents are special waste and have to be disposed of with considerable effort. Extensive environmental protection requirements must be met.
- the object of the invention is therefore to design a container for hazardous waste and hazard transport of the type mentioned in such a way that contamination of the outer container and its lid is largely avoided.
- This object is achieved in that the film inner container has a prefabricated, adapted to the shape of the sealing edge Uratschrand, which lies on the sealing edge without wrinkles, and that the lid is provided with a film made of film, covering at least the underside of the lid.
- the wrinkle-free support of the inner film container on the sealing edge of the outer container prevents contamination of this sealing edge during filling.
- the envelope edge which is adapted to the sealing edge and placed over this sealing edge, holds the inner film container securely in the outer container when it is being filled, without it being necessary to hook it onto fastening hooks.
- the cover of the cover protects the cover on the underside of the cover and in particular in the area of the usual circumferential cover seal against contamination. Since the inner film container is not tied, there are no voids in the upper container region between the inner film container and the outer container, so that during the movements occurring during transport there is no danger that the transported goods will tear the inner film container.
- the lid covering which is made of film, is pressed firmly and elastically by the lid seal against the envelope edge lying on the sealing edge of the outer container, so that a tight seal of the inner film container is ensured.
- Contamination of the outer container and in particular the underside of the lid and the sealing surfaces is largely excluded. This significantly reduces the necessary cleaning work. Closing the container is considerably simplified since it is sufficient after filling, place and close the cover provided with the cover in a conventional manner.
- the ready-made, adapted to the shape of the sealing edge of the outer container design of the envelope edge ensures on the one hand the wrinkle-free support on the sealing edge; on the other hand, a flat and cavity-free contact of the inner film container up to the upper edge of the outer container is achieved.
- the cover of the lid is designed as a flat pocket which is open on one side edge. This cover can be pulled in a simple manner over the cover which is usually articulated on an edge of the outer container and does not require any special fixing to the cover.
- the inner film container can be made in one piece with the cover edge from the same film material, which considerably simplifies production. This embodiment is preferably chosen if the entire inner film container consists of thermoplastic deformable film.
- the body of the film inner container and the cover edge is then a molded film part attached to the fuselage of the inner film container.
- This version can also be used when using uniform film material if it is useful for shaping the cover edge.
- the cover edge can be torn open on two opposite sides on a line of weakness.
- the inner film container is a shaped film part adapted to the inner dimensions of the outer container. This largely prevents damage to the inner film container due to transport movements because there are no voids between the inner film container and the outer container.
- the inner film container fits loosely on the outer container even when empty and cannot be whirled up.
- the inner film container is always in the correct position for filling and is pressed down smoothly by the filling material, so that damage is avoided even when filling.
- the invention is based on one
- 1 is a spatial representation of a container for hazardous waste and hazardous goods transport before inserting the inner film container and applying the cover
- Fig. 2 is an enlarged partial section through the closed container in the sealing area
- Fig. 3 shows a simplified section through the lid in an embodiment with a pressure relief valve.
- the container shown in the drawing is used to transport hazardous waste and hazardous goods. It has an outer container 1 made of steel, which is provided with a circumferential sealing edge 3 on its upper edge forming the container opening 2. As can be seen from Fig. 2, the sealing edge 3 is formed by a circumferential profile.
- Closing devices 6 arranged on the outside of the sealing edge 3 are intended to be connected to locking hooks 7 protruding from the edge of the lid 4 in order to tension the lid 4 against the sealing edge 3 of the outer container 1 in the closed state.
- a circumferential seal 8 on the edge of the cover 4 on the underside of the cover rests on the sealing edge 3.
- a film inner container 9 made of plastic film is adapted to the inner dimensions of the outer container 1.
- the interchangeable film inner container thus lies smoothly and without forming cavities on the inner walls of the outer container 1.
- a ready-made envelope edge 10 is provided, which is adapted to the shape of the sealing edge 3.
- the envelope edge 10 lies wrinkle-free on the sealing edge 3 of the outer container 1 when the film inner container 9 is inserted into the outer container 1.
- the outer edge 10a of the envelope edge 10 hangs down on the outside of the sealing edge 3.
- the cover 4 is provided with a cover 11 made of film, which is designed in the manner of a flat pocket which is open at least on one side edge 11a. This flat pocket is open on one side Pulled over the lid 4 in the manner indicated by an arrow in FIG. 1 and covers the top and the bottom of the lid 4.
- the inner film container 9 and the cover 11 can be removed.
- the outer container 1 and in particular the lid 4 thus remain largely free of impurities, so that cleaning work is not necessary or only to a very small extent.
- the inner film container 9 and its envelope edge 10 consist in one piece of the same film material. Since the selection of the film material can be adapted in a wide range to the mechanical, thermal and / or chemical requirements of the respective application, it may be expedient, in particular in the case of films which are resistant to high temperatures, to make the cover edge 10 from another, thermally deformable film material.
- the cover edge 10 can be designed to tear open on two opposite sides on a weakening line 12. As a result, a part of the envelope edge 10 can be folded up before emptying and placed as an apron over an adjacent frame part in order to avoid its contamination during emptying.
- an overpressure valve 4a is provided in the cover 4 (FIG. 3)
- a cutout can be provided in the film of the cover of the cover which lies on the underside of the cover, which enables free access to the overpressure valve. This cutout can be covered on the side facing the cover by a flag 13 fastened on one side which, although it allows gas to pass through, also prevents contamination of the underside of the cover at this point.
- the flag 13 is preferably offset with respect to the pressure relief valve 4a so that the pressure acting on the flag 13 cannot close the inlet of the pressure relief valve 4a.
