Waste bin

The invention is based on a reusable container, in particular a waste container. Such a reusable container can be, for example, a garbage can or a garbage container for household waste.

Such waste containers get dirty on the inside and need to be cleaned from time to time. Usually

Waste containers - if they are cleaned at all - are sprayed with a water jet and possibly cleaned by hand; cleaning agents are usually added to the water. Cleaning by hand is unhygienic; in addition, the dirt and cleaning agents are usually washed away with the
Water flushed into the sewer system.

It is the object of the invention to provide a simple - preferably
to provide reusable containers that can be cleaned mechanically.

This task is solved by a dimensionally stable, replaceable inner container. Dimensionally stable does not mean that the
Inner container must be rigid: The inner container can
for example, be elastic or collapsible. It is essential that the inner container - if it is placed in the reusable container
is inserted - retains its shape, i.e. does not
collapses or its wall collapses so that its
Opening is reduced or closed. The inner container does not have to be so stable that it retains its shape when it is removed from the reusable container.

The advantage of the invention is that the emptied inner container can be removed from the reusable container and fed into a cleaning system. This eliminates the need for manual cleaning. The environmentally friendly disposal of the dirt and
The cleaning agent can be used economically. Such a cleaning system works efficiently if enough inner containers are supplied to it, which is achieved by the
A large number of existing waste containers are ensured.

The inner containers can be replaced, for example, during garbage collection and the removed inner container can be taken to the cleaning system. Cleaning can be carried out as needed or at fixed intervals. There is no need for a second inner container for each waste container; an additional inner container for several waste containers is sufficient, as the inner container is not replaced and cleaned every time it is emptied. If the waste containers are to be cleaned every six months, for example, 27 inner containers are required for 26 waste containers, one of which is replaced and cleaned every week.

In addition, an inner container is significantly cheaper than a reusable container. The reusable container itself does not get dirty and its lifespan is extended.

In a preferred embodiment, the inner container is adapted to the shape of existing reusable containers, in particular waste containers, so that the inner container can be inserted into the reusable container without any changes to it. This means that the existing reusable containers can continue to be used.

In one embodiment of the invention, the inner container is conical or widens upwards. This means that several inner containers can be placed inside one another (stacked) and require only a small transport and storage volume. Empty inner containers that need to be cleaned can, for example, be taken away by the garbage collectors - they do not need to be picked up separately.

In principle, the outer shape of the inner container can be of any shape, as long as the inner container can be inserted into the reusable container. In embodiments of the invention, however, the shape of the inner container is adapted to the shape of the interior of the reusable container.

In one embodiment of the invention, the inner container is held in the reusable container by frictional locking, so that the inner container does not fall out when the reusable container is turned upside down and possibly shaken to be emptied.

The frictional connection between the inner container and the reusable container can be caused by an oversize inner container - a type of press fit; the oversize can exist on the entire outer surface of the inner container or only in places, for example in the area of the upper edge.

In another embodiment of the invention, a rubber or plastic ring on the circumference of the inner container or individual rubber or plastic pieces on the outside of the inner container causes the frictional connection.

In one embodiment of the invention, the inner container is inserted into the reusable container in an airtight manner; it is held in the reusable container by the air pressure (ambient pressure). For this purpose, the inner container can be manufactured to fit precisely or have a seal.

In an embodiment of the invention with a reusable container with a circular cross-section, the inner container is held in the reusable container by a bayonet lock similar to a lamp holder known from motor vehicles.

the inner container is placed in the outer container and rotated. Appropriate lugs and undercuts can be provided both on the bottom of the inner container and the reusable container and in the peripheral area. The bayonet closure can be formed, for example, by inward-facing lugs on the inner peripheral surface of the reusable container and suitable cutouts in the peripheral wall of the inner container. Such a bayonet closure can be attached to existing reusable containers without great effort - for example by screwing or gluing.

In one embodiment of the invention, the reusable container is designed as a garbage container with a lid that can preferably be pivoted about a horizontal axis and has removable stops that limit the pivoting movement of the lid, so that when the lid is open, an upper edge of the inner container remains covered by the lid. This holds the inner container in the garbage container when it is turned upside down for emptying. To replace the inner container, the stops can be removed and the lid can be opened wide enough to allow the inner container to be removed.

Parts arranged on the upper edge of the container for holding the inner container in the reusable container can be designed as engagement parts so that they are released from the machine when the inner container is removed mechanically.

In one embodiment of the invention, the inner container has handles.

An embodiment of the invention has engaging parts for mechanically removing the inner container from the

This means that the inner container can be removed from the reusable container using a suitable gripper immediately after emptying, for example during garbage collection.

In one embodiment of the invention, the dirty inside of the inner container can be turned inside out, the inner container can then be easily cleaned.

One design of the inner container has a sealing lip on the upper edge that rests on the closed lid of the reusable container. This can also be attached to the lid and seal the inner container so that it is odor-tight. This prevents unpleasant odors from the contents.

One embodiment of the inner container has a catch for the closed position of the lid of the reusable container.

In one embodiment of the invention, the upper edge of the inner container at least partially encompasses the upper edge of the reusable container. The upper edge of the inner container encompassing the upper edge of the reusable container can be designed as a handle for handling the reusable container and for removing the inner container. In embodiments, it can protrude outwards. Both the handle and the upper edge of the inner container can come into contact with a stop on a machine when the reusable container is being emptied mechanically, so that in this way the inner container is held in the reusable container during emptying.

One embodiment of the inner container has an air tube through which air can be circulated between

can flow into or out of the reusable container. The air pipe can be closable so that the inner container is held in the reusable container by the air pressure (ambient pressure).

Known waste containers are usually dark colored and therefore heat up considerably on the inside due to sunlight. The inner container according to the invention reduces the heating up on the inside because it forms a double-walled container with the reusable container.

In a further development of the invention, the outer surface of the inner container is designed to reflect heat radiation, for example by applying a gold, silver or aluminum coating. In one embodiment of the invention, the inner container has an insulating layer on its outside. This further significantly reduces the heating inside the reusable container.

Further features emerge from the following description of an embodiment of the invention in conjunction with the claims and the drawing. The individual features can be implemented individually or in combination in embodiments of the invention.

Fig. 1 and 2 show two embodiments of the invention;

Fig. 3 shows a handle according to an embodiment of the invention;

Fig. 4 shows another embodiment of the invention.

Fig. 1 shows a conventional trash can 1 as an embodiment of the invention. The trash can 1 is almost cylindrical, it widens slightly conically towards the top. The trash can 1 has a circumferential flange or is flanged on the top. It has a hinged lid 2.

The inner container 3 is adapted to the waste bin 1 and can be inserted into the waste bin 1 from above. Due to the circular cross-section, the inner container 3 can be placed in the waste bin

I can be turned; a bayonet lock similar to a lamp holder known from motor vehicles is suitable for fastening the inner container 3 in the trash can 1. However, other fastening means, e.g. the aforementioned fastening means by force fit or by negative pressure, are also suitable for holding the inner container 3 in the trash can 1.

Fig. 2 shows a mobile garbage container 4 with a wall 5 - which forms the front and rear walls as well as the floor - and two side walls 6, 7. All walls 5, 6, 7 run slightly slanted outwards towards the top. The garbage container 4 has a lid 8 that can be pivoted about a horizontal axis. The inner container 9 is adapted to the inner shape of the garbage container 4. It can be inserted from above. In one embodiment, the garbage container 4 has stops 22 that limit the opening of the lid 8 in such a way that the front edge 10 of the lid 8 touches the rear edge

II of the inner container 9. This keeps the insert 9 in the garbage container 4 when it is turned upside down for emptying, for example. The stops can be removed to remove the inner container 9 so that the lid 8 can be fully opened.

Fig. 3 shows a handle for removing and handling the inner container 3; 9: The upper edge of the inner container is cut twice, creating a tab 12. A handle opening 13 is arranged in the tab 12 - possibly with a bead 14 on the top for easier gripping. Normally, the tab 12 rests against the wall of the waste container 1; 4 due to its elasticity. To grip the inner container 3; 9, the tab 12 is bent slightly inwards and the grip is reached through the handle opening 13. The handle opening 13 can also be closed by an elastic tab cut into the tab 12, so that the inner container 3; 9 completely covers the inner surface of the waste container 1; 4; the waste container 1; 4 never comes into contact with waste.

Fig. 4 shows a reusable container 15 with inner container 16 in section. Two claws 17, which are opposite one another and may be molded onto the upper edge of the inner container 16 or otherwise attached, grip around a circumferential flange on the upper edge of the reusable container 15. This holds the inner container 16 in the reusable container 15. To remove the inner container 16, the claws 17 on the underside can be swung outwards, which releases the circumferential flange 18 on the reusable container 15. The undersides of the claws 17 are designed as handles for holding the reusable container 15 with the inner container 16 inserted or for holding the removed inner container 16 alone. The tops of the claws 17 are designed as catches for a lid 19 of the reusable container 15. They overlap the edge of the lid 19. The tops of the claws 17 and the top of the lid 19 are bevelled so that the claws 17 engage when the lid 19 is pressed onto the reusable container 15 and when the lid 19 is lifted off the

Reusable container 15 can be pushed to the side and the lid can then snap into place or be released. A sealing lip 20 on the upper edge of the inner container 16 seals the lid 19 that is placed and snapped into place on the inner container 16. This prevents unpleasant odors.

A pipe 21 runs upwards inside the edge or in a corner of the inner container 16. The pipe 21 ends at the top at the edge of the inner container 16; at the bottom, the pipe 21 opens out onto the outside of the inner container 16. Air can escape from the inside of the reusable container 15 through the pipe 21 when the inner container 16 is inserted and flow into the inside of the reusable container 15 when the inner container 16 is removed. This prevents overpressure or underpressure between the reusable container 15 and the inner container 16 and thus makes it easier to remove and insert the inner container 16.
