The invention relates to a collection device for being arranged in a toilet chair, which collection device comprises a bowl-shaped insert part with an upper edge, an outer side, an inner side and a bag.

Today, there exist different bags which can be mounted in a bowl of a toilet chair such that the bag collects the faeces and urine which are delivered in the toilet bowl.

The bags promote cleaning and hygiene since the toilet bowls in which bags are used do not come into direct contact with the faeces. Furthermore, a bag with faeces can be easily removed from the toilet bowl without the user coming into contact with the content. If the bag remains tight, this is rarely associated with problems, but nevertheless accidents occur, and accidents are often due the bag not staying tight.

An attempt has been made to solve this by forming the bags with a greater strength, but even a greater strength in the bags does not often solve the problems in terms of faeces or urine leaking out of the bags. The leakage often occurs through holes in bags torn apart. This problem has been tried to be solved by a bowl-shaped insert part constituting a watertight barrier which is much more durable than a bag in itself. Such insert parts are normally made such that they comprise a bowl-shaped unit, wherein the bowl itself is of such size that faeces and/or urine from a person can lie therein, but even with a watertight and durable bowl-shaped insert part arranged in a bag, accidents occur when the bag is not arranged properly in relation to the bowl-shaped insert part. Because when the bag is not arranged properly, the bowl-shaped insert part can be tilted or can even tip over if the bag with bowlshaped insert part is lifted, whereby urine and/or faeces is running out of the bowl-shaped insert part and further into the bag.

This is a problem when the bag is not tight.

A collection device for being arranged in a toilet chair is known from DE 202018002751 U1, this collection device comprises a round part, formed as a tyre or a hose, and a bag, wherein the bag is attachable to the round part.

In the known collection devices, soft plastic bags are used and they are manipulated when being used since they are to be ’’unfolded”. This manipulation strains bags and therefore bags are sometimes destroyed during this manipulation. This is especially a problem when the collection device is used in connection with a toilet bowl as a manipulation of the bag is necessarily going to take place when the collection device will be placed in the toilet bowl or removed therefrom. It is an object of the invention to remedy one or more of these problems and/or other problems associated with the prior art.

Another object of the invention is to provide an alternative solution.

This is achieved by the invention in such a way that the bag and the bowl-shaped insert part are mutually adapted such that the bag can enclose the bowl-formed insert part and in such a way that the bag is attached to the outer side of the bowl-shaped insert part.

By attaching the bag to the outer side of the bowl-shaped insert part, it is ensured to an increased extent that the two parts - i.e., the bowl-shaped insert part and the bag - are not offset in relation to each other during use. This applies both when the collection device is placed before use, but it is, in particular, an advantage when the collection device (bag and bowl-shaped insert part) is lifted after use. Thus, when the two parts are mutually attached, a user can adjust his lift such that the bag with the bowl-shaped insert part is lifted without tilting the bowl-shaped insert part. This minimizes the risk of the content in the bowl-shaped insert part running out into the bag, and hence, the risk of leakage out of an untight bag is also minimized

Thus, the fact that the bowl-shaped insert part maintains its position in the bag minimizes the risk of spilling faeces when a collection device is used, and a bag with a bowl-shaped insert part is subsequently to be lifted with the filled bowl-shaped insert part.

Normally, the bowl-shaped insert part is made with a flat bottom in order to be able to stand on its own when being placed on a flat surface as, for example, at the bottom of a toilet chair.

In one embodiment the bag is configured with hand grips (handles, for example).

In a further embodiment, these are placed such that the attachment between the bag and the bowl-formed insert part is located substantially vertically below the center of gravity of the bowl-shaped insert part with the bag with the insert part therein being lifted by means of the hand grips.

In one embodiment, the bowl-shaped insert part is formed such that this center of gravity is moved substantially vertically when the bowl-shaped insert part is filled with liquid (or emptied).

In one embodiment, the bag is attached to the outer side of the bowl-shaped insert part by means of glue. In one embodiment, the collection device comprises a bowl-shaped insert part which is joined to the bag by a welding such that a region on the outer side of the bowl-shaped insert part is melted, and that the melted material is applied to the bag in such a way that the bowlshaped insert part and bag are attached to one another after cooling of the applied material. It may also be a region on the bag which is melted and that the melted material is applied to the bowl-shaped insert part such that the bowl-shaped insert part and bag are attached to one another after cooling of the applied material.

In one embodiment of the invention, the junction has been carried out at several positions such that the bag and the bowl-shaped insert part are sitting together at several locations.

Thereby the two parts are further prevented from moving in relation to each other. If the bag and the bowl-shaped insert part are only assembled at one point, the bag can be pivoted around this point in relation to the bowl-shaped insert part, and the two parts can thereby be separated. Moreover, the pointwise interconnection at several locations also ensures that the bowl-shaped insert part is easier placed in a toilet bowl in a manner that is correct according to use.

In one embodiment, the one or more pointwise interconnections have been carried out in the bottom of the bowl-shaped insert part. This ensures to an increased extent that the bag and the bowl-shaped insert part are placed in a mutually correct manner.

In one embodiment, the bowl-shaped insert part and bag are made in materials which can be heated, melted and mixed, thereby being able to weld the bag and the bowl-shaped insert part together, and this welding-together can be made at one or more locations in the bottom of and/or on the sides of the bowl-shaped insert part.

In one embodiment, the bowl-shaped insert part is formed as a bowl with a bottom and one or more flanges along the upper edge(s) of the bowl in such a way that the one or more flange(s) of the bowl can be used as seat by a user.

In one embodiment, the insert part is configured with a strength adapted such that the bowl will not collapse when the flange of the bowl is loaded with a user’s weight of up to 120 kg.

In one embodiment, the insert part is configured with a strength adapted such that the bowl will not collapse when the flange of the bowl is loaded with a user’s weight of up to 100 kg.

In one embodiment, the insert part is configured with a strength adapted such that the bowl will not collapse when the flange of the bowl is loaded with a user’s weight of up to 50 kg.

In one embodiment, the insert part is configured with a strength adapted such that the bowl will not collapse when the flange of the bowl is loaded with a user’s weight of up to 25 kg. For linguistic reasons, it is preferably mentioned in the patent text that the collection device is used for the collection of faeces, but the collection device is used equally well whether it collects urine, faeces or a mixture thereof.

One embodiment of the invention will now be explained with reference to the Figures in which:

Fig. 1 shows a collection device;

Fig. 2 shows a toilet chair in which the collection device can be used;

Fig. 3 shows a bowl-shaped insert part formed with a cone-shaped hollowness;

Fig. 4 shows a collection device, wherein the bowl-shaped insert part is formed with a cone- shaped hollowness;

Fig. 5 shows a conventional toilet provided with a collection device, wherein the toilet seat is put up;

Fig. 6 shows a conventional toilet provided with a collection device, wherein the toilet seat is put down;

Fig. 7 shows a system with a collection device and a foldable toilet chair;

Fig. 8 shows a bag with a bowl-shaped insert part, wherein the bowl-formed insert part is formed with a flange 3 a.

Figure 1 shows a system comprising a collection device 1 with a foldable toilet chair.

The collection device comprises a bowl-shaped insert part 2 with an upper edge 10, an outer side 11 and an inner side 12. In the shown embodiment, the outer side is convex, and the inner side is normally concave, but not necessarily.

The bowl-shaped insert part itself can thus have many forms, and in Figure 1 it is formed as a bucket. The bowl-shaped insert part with bag can also be made such that they are stackable in the same way as glass or disposable mugs which are inserted into each other.

The configuration shown in Figure 1 is adapted for the use in a toilet chair as shown in Figure 2. Besides the bowl-shaped insert part, the collection device comprises a bag 3. The bag 3 can be provided with a closing mechanism 4, such as with a cord, as it is known from garbage bags, for example.

The bag and the bowl-shaped insert part are mutually adapted such that the bag 3 can enclose and be closed around the bowl-shaped insert part 2 as shown in Figure 1.

In the shown embodiment, the bowl-shaped insert part 2 is made with a flat bottom 5. This has the advantage that the bowl-formed insert part can stand on a plane support. Normally, the bag 3 is attached to the bowl-shaped insert part in the bottom 5 thereof and the attachment has normally been carried out approximately in the middle of the bottom.

The attachment itself - which is not apparent from the Figures - does not need to be carried out in the middle of the flat bottom, but it can be advantageous if this is carried out in a point which lies substantially below the center of gravity of the bowl-shaped insert part since the bowl-shaped insert part is thereby prevented from tilting when a user - via the bag - performs a symmetrical lifting in order to lift the collection device out of a toilet bowl, for example.

The word ’’substantially” is to be understood as follows: the changes which can be made by a person skilled in the art.

However, a symmetrical lifting can be obtained in other ways, for example, by the attachment of the bag to the bowl-formed insert part at more locations in the bottom thereof and/or at more locations on the outer side of the bowl-shaped insert part. The attachment can be carried out by means of glue, but clearly other methods known to the person skilled in the art such as ultrasonic welding can also be used.

A combination of different attachment methods can also be used.

Figure 2 shows a toilet chair 6 with a toilet bowl 7 in which the collection device can be used.

Today, there exist hard bowl-shaped insert parts for the use in toilet bowls. But experience shows that urine will often hit next to the hard insert bowl which is why subsequent cleaning is correspondingly often required. This is resource-consuming.

Today, there are also bags for the insertion in such toilet chairs, but unfortunately it has turned out that the bags are often untight, which is the reason why the toilet bowl itself correspondingly often gets dirty. This is time-consuming for those who subsequently have to clean the toilet bowl, but often it is also psychologically unpleasant for the user to leave behind a dirty toilet bowl. The leaks are often due to the fact that the bag is destroyed when being inserted or taken out of the toilet bowl. Because the bag is thereby manipulated, and if the toilet bowl is at least moist, as for example due to cleaning, the bag will have a tendency to ’’stick” to the bowl for which reason the bag can be torn apart when being placed in the toilet bowl and/or being taken out of the toilet bowl after use.

The collection device according to the invention comprises bag as well as bowl-shaped insert part.

Figure 3 shows an embodiment of the invention with bag 3 and bowl-shaped insert part.

In this embodiment, the bowl-shaped insert part 2 is configured with a flat bottom 5, thereby being capable of standing on a plane surface. In this embodiment, the inner concave side is made with a conical-shaped hollowness 20. The hollowness 20 is normally conical-shaped but does not need to be. However, it can be advantageous if the hollowness 20 defines a center of gravity which moves substantially vertically when the insert part is standing on a horizontal surface while being filled with liquid.

For this can be used in an embodiment, wherein the collection device comprises a bag 3 and a bowl-shaped insert part 2 with flat bottom and such a hollowness as the junction 9 between bag 3 and the bowl-shaped unit can be carried out in one point lying under the above- mentioned center of gravity which moves if the conical-shaped hollowness 20 is filled with liquid.

This has the advantage that a user can collect the bag symmetrically around a filled bowlshaped insert part and subsequently lift the bag with its content without the content in the bowl-shaped insert part causing ” an oblique lifting” in the assembly between bag and the bowl-shaped insert part.

Should the assembly between bag and the bowl-shaped insert part be carried out in such a way/here, the bag would further be adaptable in such a way that it will be provided with one or more lifting devices, for example, in the form of one or more handles placed such that the center of gravity of the ’’moveable center of gravity” is located over the junction when lifting the collection device by means of the lifting devices. This would entail the advantage that the collection device can be lifted - by means of, for example, the one or more handles - without a content of liquid in the conical-shaped hollowness ’’tilting” the bowl-shaped insert part. This minimizes the risk of leakage.

The embodiment shown in Figure 3 is preferably made such that the collection device can be used as an ordinary potty since the upper edges 10 on the bowl-shaped insert part 2 are made so that it (or they) can be used as seat by a user.

In one embodiment this is obtained by providing the upper edge 10 with a flange adapted such that it can be used as a conventional toilet seat.

The bowl-shaped insert part itself can also be configured such that it can be folded out/in or be merged.

In one embodiment, this feature is configured such that the bowl-shaped insert part - in its folded state - has the strength which is necessary for the bowl-shaped insert part to be capable of being used as potty. This means that a user must be able to sit down on the insert part, (and in the embodiments in which it is configured with a flange, on this) without this causing a collapse. This embodiment can also be made in different embodiments in terms of strength, wherein each embodiment of the bowl-shaped insert part can carry humans of up to a certain weight. Up to 25 kg or up to 50 kg or up to 100 kg or up to 120 kg, for example. The advantage of making the bowl-shaped insert part foldable is that it takes up less volume in the folded state, for which reason the distribution of many bowl-formed insert parts becomes easier in terms of transportation with applied bag, to refugee camps, for example. As explained below with reference to Figure 8, the bowl-shaped insert part can be made with a flange, enabling it to be inserted into an opening - as in a box - with the flange abutting against the box around the opening. In this way, the box can be used as a toilet chair carrying the weight of the user. The collapsible insert part with flange - as explained above - is particularly easy to make for the usage in boxes as it is normally less complicated to manufacture a collapsible bowl-shaped insert part if this - in itself - is not intended to carry the weight of a user. A collapsible bowl-shaped insert part with flange can be made such that the bowl-shaped insert part can be telescopically extracted and compressed in the same way as telescopic binoculars and this has obviously advantages in terms of space since telescopic (extractable) bowl-shaped insert parts can be stored in their compressed state until they need to be used. Figure 4 shows an embodiment of the bowl-shaped insert part 2, with a concave hollowness 20, in this embodiment the bowl-shaped insert part is configured with flat bottom 5 and an outer side that curves inwards. In this embodiment the bag 3 is provided with a closing device 4 which also defines a lifting point/device - which lies substantially over the center of gravity of the bowl-shaped insert part as well as the junction 9 between bag 3 and bowl-shaped insert part 2. In this way, the bag 3 with bowl-shaped insert part 2 can be lifted at the closing device 4 without the bowl-shaped insert part ’’tilting”.

It is shown in Figure 5 and Figure 6 how a collection device according to the patent can be used in a conventional toilet 20.

Figure 7 shows an embodiment of a system in which a foldable toilet chair 100 is integrated. This toilet chair that can be made of thin wood, plastic, hard cardboard, plywood or the like comprises four sides: 101 ,102,103, 104 and a top surface 105. In the shown embodiment, the four sides and the top are made such that they can be assembled in such a manner that they constitute a box 100 with an opening 106 in the top side/top surface 105. The box 100 is mutually adapted to the collection device 1 so that the collection device can be placed in or below the opening 106 of the top surface. In this way, the box 100 can act as a toilet chair since the top surface 105 with opening 106 acts as (toilet) seat while the collection device is located below the opening.

Figure 8 shows an embodiment wherein the bowl-shaped insert part 2 is configured with one or more flanges 3a on the top edge. In this embodiment, the bowl-shaped insert part 1 with the one or more flanges is adapted to an opening as, for example, the opening 106 in the box 100 such that the bowl itself on the bowl-formed insert part 2 can pass through the opening 106 while the flange 3a is not capable thereof. In one embodiment, the collection device with bowl-shaped insert part and bag 3 is adapted to a box portion 100 with a top surface 105 with opening 106 such that the bag 3 can be placed on the top surface 105 while at the same time the bag is placed around the opening 106. This ensures an increased hygiene as a user can sit down on the bag when he/she uses a box with collection device as toilet.

The flange 3a on the bowl-shaped insert part provides a simple and hygienic mounting or removal of the bowl-shaped insert part in or from a box 100 or toilet part formed with an opening adapted thereto.

The modular box itself as explained with reference to figure 7 provides together with the collection device a modular system in which the bowl-shaped insert parts can be changed between the users and where the box 100 itself can also be easily separated. This has the advantage that the single parts of the box or the entire box 100 can be changed when needed, for example, if a user accidentally pollutes the box or parts thereof. The fact that the box is composed of plates as explained with reference to Figure 7 makes it easy to store many boxes as the plates of the boxes can be stacked until usage.

In all figures the bowl-shaped insert part is formed as a round bowl, but of course it can have many other forms, square or triangular form, for example.

A bowl-shaped insert part with a flange 3a is shown in Figure 8.

As explained above, the flange 3a can advantageously be adapted to an opening such that the flange is going to abut against the sides of the opening when inserting the bowl 3 of the insert part through the opening, but the flange 3a does not need to be adapted to an opening. If the bowl-shaped insert part with flange is adapted to an opening, the bowl-shaped insert part does not need to carry the weight of a user as it would normally be the item (a box, for example) with the opening which will be formed in such a way that it is capable of carrying the weight. However, the bowl-shaped insert part can also be formed with a strength and a size causing the bowl-shaped insert part to be able to stand on an underlying surface and to carry the weight of an adult person (up to approximately 110 kg), who uses the flange as toilet seat, and a bowl-shaped insert part formed such can also be made so that the flange can be placed around an opening. Clearly, the strength of the flange and insert part can also be adjusted to less weight as, for example, the weight of a child.

In all embodiments, the collection device and the box 100 can be completely or partially made by biodegradable materials, and the collection device can also, in all its embodiments, be provided with a liquid-absorbing inlay which is preferably placed in the bowl itself.
