Abstract

A storage unit (1) and methods to be used to reduce nuisance from the contents, for instance from organic waste from households sorting the waste according to kind, said unit comprising an outer receptacle (2), usually provided with at least one openable lid (3), and a bottom member (10). The outer vessel (2) is provided with a number of air vents (4) to allow circulation of air in the receptacle interior, and further with a suspension device (5) which is attached to the receptacle (2) or is in the form of a separate insert (6) incorporating said suspension device (5). This suspension device allows attachment of on the one hand at least one outer supporting bag (7) and on the other at least one inner paper bag (8) in such a manner that when the lid (3) has been opened organic waste may be deposited inside the paper bag (8) which is enclosed and is supported by the supporting bag (7). The latter is constructed in a manner, for instance by having a woven or perforated structure, to allow air and gases to enter into and/or leave the paper bag through said supporting bag. Upon emptying, the paper bag is closed so that together with its contents it forms a package that easily slides out of the supporting bag.

Description

507 984 10 15 20 25 * 30 35 the bag through the support bag.

This means that this construction creates a good outer vessel and a possible insert placed in this will not be ventilation of the waste inside the paper bag. dirty because the paper bag is surrounded by a support bag. Because the support bag is permeable to gases, good ventilation of the paper bag and its contents is made possible. If the contents of the paper bag soak through it, the support bag will become dirty over time. This is especially true if the paper bag breaks. the contents of the support bag are washed in a sink or the outer vessel. This is of course a After emptying, the support bag can then be removed and washed. Normally, the insert rarely needs to be washed. very big advantage. Good ventilation of the waste greatly reduces the development of bacteria and unpleasant odors.

The good ventilation of the waste is thus of fundamental importance. It is ensured partly through the use of an inner paper bag surrounded by a perforated support bag, for example a support bag made of man-made fibrous fabric, and an enclosure of the support bag which provides a good In many cases, it is relevant to plastic containers. These containers are often found in large quantities and waste collection ventilation of this. Utilizing existing, substantially dense equipment is specifically tailored to them. This is done by creating real air openings in the outer vessel, for example in the form of insert valves with protection for flies and the like, for example in the form of fibrous fabric or nets. A gas-permeable (both sides and bottom) insert specially adapted to the vessel in question is then produced. It is designed in such a way that it can attach the support bag and the paper bag in the desired manner, after which the insert is lifted into place in the outer vessel and anchored therein. Initiatives of the kit set model may also be relevant.

The handling when using the storage unit can be described as follows. The paper bag from the storage unit in the kitchen (8-15 liters) is closed and placed in the 10 15 20 25 30 35 3 3 of the garbage truck. But even with such a solution, the problems of cleaning the vessels remain, which, as it turns out, are very serious.

OBJECT OF THE INVENTION The object of the present invention is to substantially reduce the above-mentioned problems by creating a storage unit and methods for utilizing it, which enables the waste to emit water vapor and other gases and to supply air (oxygen). This significantly improves the hygienic conditions around both the sorting in the kitchen and the continued handling. The storage unit according to the invention can thus be found partly in a smaller size for the kitchen and partly in a larger one for the continued handling.

Existing plastic containers can easily be converted to the storage unit described here by being provided with the necessary ventilation and otherwise supplemented with the described equipment (insert).

SUMMARY OF THE INVENTION The above object is achieved in that the storage unit and the methods for its use exhibit the features stated in the appended claims.

The storage unit according to the invention is thus essentially characterized in that the outer vessel is provided with a number of air openings, which enable air circulation inside the vessel, attached to the vessel or in the form of a detachable and further provided with a suspension device, insert containing the suspension device , which suspension device enables attachment of an outer support bag and an inner paper bag, so that after the lid has been opened, organic waste is placed in the paper bag which is surrounded and supported by the support bag, which is so designed, for example by a woven or perforated structure, that air and gases can come to and / or leave paper 507 984 10 15 20 25 30 35 6 it is relevant to empty the container. The method is characterized in that the waste from the kitchen, suitably enclosed in a paper bag, is placed in a storage unit, which consists of an inner paper bag, surrounded by a support bag, in turn surrounded by an outer vessel, which is provided with an openable part, and the support bag , the vessel and insert are so designed that air and gases can enter and / or leave the paper bag through the support bag, and when the paper bag is filled to about half, the top is rolled up and the support bag is released from its suspension and closed, after which it rests on the bottom of the vessel, after which a new support bag with an internal paper bag is lowered into the vessel and rests on top of the previous bag, and when the new bag is half full, the openable part is opened (alternatively the upper part is lifted away from a loose bottom) and the free lower bag is pulled out and is taken to composting, for example in the garden land, and after about a year the contents are decomposed, so that the support bag can be reused.

Further features of the invention and advantages thereof are set forth in the following detailed description of exemplary embodiments.

DESCRIPTION OF THE DRAWING Fig. 1 shows a storage unit according to the invention, which consists of an outer vessel and an inner insert. The inner insert first has a support bag and inside this a paper bag. This can be seen in the right part of the picture, while in its middle part the paper bag is cut away, and in its left part both bags are cut away.

Fig. 2 shows an insert which is constructed according to a kit procedure. This allows the user to easily adjust the size of the insert to the size of an existing outer vessel.

Fig. 3 shows the insert according to Fig. 2 placed in an outer vessel, which is adapted for automatic emptying. 10 15 20 25 30 35 507 984 5 larger storage unit in the yard or in the garbage room (60 - 160 liters). In addition to its upper part, the support bag included in the storage unit is also anchored in its lower part to the outer vessel (directly or via the insert) so that it must not be turned out of the vessel in connection with emptying in the refuse truck.

In the central treatment of the waste, the waste must be collected with the help of a suitable vehicle (garbage truck) and then the following method can be used to handle the waste. The waste from the kitchen which is suitably enclosed in a paper container, which consists of e.g. a paper bag is placed in a storage unit, by an inner paper bag, surrounded by a support bag, in turn surrounded by an outer vessel, and possibly an insert. The support bag, the vessel and the insert are designed in such a way that air and gases can reach and / or leave the paper bag through the support bag. The support bag is attached in its lower part to the outer vessel, directly or via the insert. Before emptying, the inner paper bag is closed so that when emptying, for example 1 garbage truck, it can easily slide out of the support bag, which is not turned over. If an outer vessel or sack holder is used, which are specially adapted for the method, only the support sack and paper sack are used, ie.

In this case, the lower part of the support bag is attached to the outer vessel or bag holder, so that twisting is limited. If, on the other hand, an insert is used, the support bag is similarly attached to the lower part of the insert, which is then lifted into the outer vessel and anchored therein.

When the storage unit is to be used for local special operations. posting, a slightly different method is used, and the requirements for the storage unit differ slightly from the previous case.

In this case, it is advisable to use a storage unit without insert, and the storage unit must be provided with an openable part at its lower end.

Alternatively, a loose bottom unit was used. When emptying, lift the upper part away from the bottom, when the support bag (with contents) is exposed. No anchoring of the lower part of the support bag in the outer vessel is required, since there is no space by the snap action between valve and hollow wall. The valves are suitably provided with protection against flies and the like, for example in the form of fibrous fabric or fine-mesh net. To protect, for example, the fibrous fabric against damage, the air openings 4 are provided with protection 9. These can be of the plastic or metal grid type. In the embodiment shown, the cover 9 is suitably provided with, for example, fibrous fabric glued to the inside of its grid pattern.

The waste, usually organic waste, which is placed in the storage unit 1 ends up in the inner paper bag 8.

Air and gases can escape or enter through the paper in the paper bag 8. Since the waste inside the paper bag is often wet, the paper bag 8 risks getting wet and losing some of its strength. This is not a problem, since the paper bag is surrounded by the support bag 7, which is designed, for example by a woven or perforated structure, that air and gases can come to and / or leave the paper bag through the support bag. As a result, the paper bag also dries out. of man-made textile fabrics. The support bag is thus designed in such a way. Usually a support bag is used that it lets air and gases through, at the same time as it retains its strength even in the wet state. The air-permeable support bag 7 thus functions as a covering for the insert 6.

It is folded over the upper edge of the insert and clamped with a strap 28. This is important, since when emptying only the inner paper bag 8 must be emptied out of the insert. The paper bag 8 is folded over the edge of the insert 6 and the support bag 7. back over the edge and sealed, 4 and 5.

The insert 6 in fig.

Before emptying, the paper bag is folded, for example according to Fig. 1, is specially made to fit a certain outer vessel 2. The insert can, for example, be made of plastic in approximately the same way as a laundry basket.

Normally, it is also anchored to the outer vessel 2, so that it is retained when emptying the vessel in a garbage truck. In such emptying, it is also important that the support bag 7 is not turned out of the insert when the paper bag 8 10 15 20 25 30 35 507 984 7 Fig. 4 shows an inner paper bag, which is provided with a sealing band.

Fig. 5 shows how the top of the paper bag is rolled up and the sealing tape is brought up around the end of the bag to provide a simple and secure closure thereof.

Fig. 6 shows an outer vessel, which is designed in such a way that no detachable insert is required. The vessel has a lid attachment, which enables the lid to be rotated relative to the vessel.

DESCRIPTION OF EMBODIMENTS In Fig. 1, l denotes a storage unit primarily intended for source-sorted organic waste from households. But the unit can also be used to reduce storage inconveniences from e.g. other types of waste or products, as storage is an advantage of an aerobic environment. The storage unit 1 consists in Fig. 1 of an outer vessel 2, in which a detachable insert 6 is placed. The basic idea in this case is that the insert 6 is used to convert an existing outer vessel 2, so that it is useful for either or more of the storage methods according to the invention. The insert rests on an approach or on the bottom of the vessel 10. The containers currently used for handling organic waste usually have no or extremely limited ventilation. The storage methods according to the invention, on the other hand, are based on air and gases being able to enter and / or leave the waste in the storage unit 1. Therefore, the existing outer vessel 2 has been provided with a number of air openings 4, so that air can enter the vessel and air or gases can leave the vessel. The arrows in the figure show how air penetrates through low-placed air openings 4 and further in through the detachable insert 6, and also in through its perforated bottom 10 '. Air and gases leave the insert 6 and penetrate through high-positioned air openings 4. The air openings 4 are shown here as round insert valves, but of course they can also be designed in other suitable ways. In this case, holes are made with, for example, a hole saw, after which the valves are pressed into place. They are held on 507 984 10 15 20 25 30 35 10 in strips which are anchored in the upper edge of the vessel and whose length can be adjusted. The support bag 7 is available in a number of sizes to enable an adaptation to different sizes of outer vessels 2. The support bag 7 has a tunnel 16 for each support leg 12. The tunnels have been created by folding down the top edge of the bag and then gluing or fusion welding on either side of it intended tunnel.

When the insert is used in a vessel that is emptied, it is important that the support bag 7 is attached to the insert 6 and that the insert 6 in turn is attached to the outer vessel 2.

Emptying in the garbage truck takes place according to the previously described method. The support bag 7 is therefore provided with a number of fastening loops 13, which are fastened in the bag brackets 14 in the bottom part and provided with one so that fastening tongues 14 are formed. Respectively 10. In the example shown, the bottom 10 'has a number of cut-outs, the fastening loop 13 is fed into a suitably placed fastening tongue 14. Thus, the bottom of the support bag is held firmly in the bottom 10' of the insert, so that the support bag does not twist when emptying.

Usually the same support bag 7 can be used for a long time, since it is protected by the inner paper bag 8. But if the support bag should be worn or soiled, for example by the paper bag breaking, it can be easily replaced. The fastening loops 13 are then loosened and the support bag 7 so that the support legs 12 hit in resp. tunnel 16, after which the fastening loops 13 are fastened in the bottom part 10 '. Then the whole insert is lifted and placed in the outer vessel 2, pulled loose upwards. A new support bag is then lowered, resp. as shown in Fig. 3. The figure shows how the insert brackets 15 are clamped up to the corners of the outer vessel 2. Hereby the insert itself is clamped up inside the vessel. When emptying, the insert brackets 15 prevent the insert from falling out of the outer vessel 2. Of course, the brackets 13 for the support bag and the brackets 15 for the insert can also be designed on and off in the refuse truck. many other ways, provided they fulfill their function. Fig. 1 does not show these mounts for clarity. But if the storage unit 1 is to be emptied, for example in a garbage truck, 10 15 20 25 30 35 507 984 9 falls out of the insert. Methods for attaching the insert 6 resp. the support bag 7 is shown in more detail in Fig. 2, which shows an alternative insert. This is of the "kit model" and can therefore fit several different existing outer vessels 2.

This is particularly interesting if the number of existing vessels of a certain type is so low that it does not justify the tool cost of producing a completely adapted insert according to Fig. 1.

Fig. 2 thus shows an insert 6 of construction kit model and provided with a adapted support bag 7. The insert 6 thus consists of three main parts, a bottom 10, a support bag 7 and a number of support legs 12, here four pieces. The bottom 10 is built up in sections in the longitudinal and transverse direction. It has a plurality of mounting holes 11 for the support legs 12. In the example shown, one or two longitudinal sections can be separated.

There are still mounting holes for the support legs. Of course, there can also be more mounting holes in the transverse direction, so that sections can also be separated in the transverse direction. The boundaries between the sections are so designed that they can be easily cut or sawn off. In this way, the size of the bottom can thus be adjusted, so that it is suitable for various existing outer vessels 2. The support legs 12 are suitably of plastic or metal, e.g. aluminum. They are lowered into their respective mounting holes 11 in the bottom part 10 '. Through the pressing of resp. support leg, a support of the support leg in the fastening hole 11 is obtained.

Namely, the mounting hole has a guide for the support leg 12 and is a bottom hole. The support leg is thus pressed in for extra locking, a screw can be screwed in from made as a stop. Like the underside of the bottom. This screw is then suitably self-tapping in the inside of the pipe. Under the bottom of the insert there is often a support which transfers the weight from the waste to the bottom of the outer vessel, alternatively the bottom of the insert is screwed to the sides of the vessel or suspended in strips which are anchored in the upper edge of the outer vessel. The height of the insert 6 is adapted to the outer vessel by cutting the respective support legs 12 to the desired length. Alternatively, instead of 10 ', a rigid bottom, a net bottom can be used which is suspended 507 984 10 15 20 25 30 35 12 both ends of which are attached to the paper bag 8. Preferably the fastening is made in approximately vertical direction as the figures show. The sealing tape is suitably made of a paper material just like the bag 8. Thus it breaks down as fast as the bag itself. The closure belt 20 creates a simple and secure closure of the paper bag 8. Through the closure, the waste remains in the bag during the entire emptying process, which reduces the hygienic risks for the cleaning workers.

Fig. 6 shows a storage unit 1, which is specially manufactured for the storage method according to the invention. It is designed in such a way that it does not require any insert 6 but only consists of an outer vessel 2. The vessel 2 can, for example, be made of expanded metal, which has the advantage that no pests can gnaw heels on the container. But it is also conceivable that the vessel can be made of plastic, provided that it is made so that it cannot be damaged by pests. The vessel 2 suitably has a round section, since it then corresponds to the basic shape of the support bag 7.

With a round vessel, it is also particularly easy to make the rotatable lid 3, which is shown in the figure. The lid is attached in a conventional manner to a lid bracket 21. This in turn is slidably mounted in a support profile 22, which is fastened around the vessel. The support profile 22 is shown here as a T-profile, but of course other shapes are also conceivable. This allows the lid to be rotated around the vessel 2. Normally, the wheel and lid bracket are placed on the same side of the vessel 2. This means that the vessel must be turned when it is put in place. Otherwise the lid would be in the way, when waste must be placed in the container. With the sliding lid bracket 21, only the lid needs to be turned around half a turn, which is of course easier than turning around the entire vessel 2.

This eliminates the disadvantage of today's vessels that the vessel must be turned 180 ”at the installation site partly in connection with the collection and partly in connection with the restoration. In the new embodiment, the vessel is prepared for 10 15 20 25 30 35 507 984 ll, they must of course be present. For example, when the support blankets can be placed in the insert resp. fastening loop 13 is extended through an opening in the grid pattern of the insert near its bottom.

It can then be locked in any suitable way, for example by being moved around a section in the base strip 17 on which the insert stands. The bottom strip is made in sections and then passes through the openwork bottom 10 '. It is also possible to provide the insert 6 with one or more opening SOITIs at intervals which allow air to slip in, releasable or detachable doors. They are then suitably located in the bottom of the insert or near its bottom, and simplify the handling of the support bag 7 and its locking to the insert. For fastening the insert 6 in the outer vessel 2, a fastening device placed high up in resp. Container. This makes it more convenient to handle the device. For example, screws that are screwed in through the outer vessel 2 could cooperate with adapted halves in the insert 6.

As can be seen from Fig. 3, the outer vessel has on its front side a fastening device 18 to enable automatic emptying of the vessel. The fastening device can be designed in many ways, but here it is made in the form of a transverse strut 19, Thus a claw in the gripping device can grip around the transverse strut, which bridges a recessed part 18 of the front. 19. For the sake of clarity, the figure does not show any lid, but one is normally used. It is attached to the back of the container above the wheels as well as to the alternative according to Fig. 1. Thus, the lid comes out of the way during the automatic emptying in the garbage truck.

Figs. 4 and 5 show an inner paper bag 8 provided with a special sealing tape 20. As can be seen from Fig. 1, the paper bag is placed inside the support bag 7 and its edge is folded over the edge of the insert 6. When it is time for emptying, the edge is folded off the paper bag up and then rolled up a few turns. The sealing tape is then passed over the rolled-up part of the bag and held together. The sealing band 20 has a suitable length and 507 984 10 15 20 25 30 35 14 Fundamental to the storage methods according to the invention is that good ventilation of the waste is created.

All embodiments shown therefore have a ventilating bottom. Of course, a non-ventilating bottom can also be used, but then the method works worse, e.g. there is a great risk that the bottom of the paper bag is soaked up so much that it breaks. Furthermore, of course, the attachment of the support bag both at the top and at the bottom can take place in a number of different ways within the scope of the invention. 10 15 20 25 30 35 507 984 13 emptying by turning only the lid 180 ”. When the vessel has been emptied, the lid is turned again 180 ° and the vessel is then ready for refilling. The lid can be locked in the "emptying" or "filling" positions, and the new version also makes better use of the available container volume.

For mechanical emptying in a car, certain reinforcements and connection details are needed, which are adapted to the lifting devices that are available on current pick-up cars.

Such reinforcements and connection details are not shown in the figure, as they are of no significance in this context for illustrating the principles in the new storage unit. As in previous cases, a fastening of the lower part of the support bag 7 to the outer vessel 2 is then required. In the case of mechanical emptying, a fastening device 19 similar to that in Fig. 3 can also be required. for example with fastening loops 13. The fastening of the bags in the upper part of the vessel takes place, for example, in the same way as with the insert in Fig. 1.

If, on the other hand, the storage unit 1 is used for local composting, no lower attachment of the support bag 7 is required. Furthermore, no rotatable lid or wheel is required either. However, an openable door 23 is required in the lower part of the vessel. Namely, through the opening which is exposed when the door 23 is opened or removed, the lowest closed support bag with the paper bag lying inside must be removed to be taken for post-composting. Alternatively, the top of the storage unit can be lifted off a loose bottom when the bottom support bag is removed. What has been said about ventilation of the waste in the designs according to previous figures obviously also applies to this case. Alternatively, two or more storage units can be used for composting, where there are larger amounts of waste. In this case, it is more rational for the outer ventilated container to be conical with a loose bottom. During emptying, the outer container is lifted off from the loose perforated bottom part and the support bag with embedded paper bags and pre-composted waste is closed and transported to a suitable place for post-composting, e.g. next to the garden land. 507 984 10 15 20 25 30 35 16 16 on the bottom (10) of the vessel (2), whereby the insert (2) can be provided with bags (7, 8) and then lifted into the outer vessel.
