Description

Device for packaging waste

The invention relates to a device for packaging waste, in particular odorous and/or infectious waste.

In the operating rooms of hospitals or in the field of intensive care, in particular, a large amount of infectious and odorous waste is generated that must be disposed of. As a rule, bags of different sizes are kept ready for this purpose, which collect the waste in the form of bandages, swabs, etc. Once the bag is full, it is closed and the waste in it is disposed of.

Odorous waste, such as diapers, is placed in bags or buckets in an appropriate manner and then disposed of when the containers are full.

It is an object of the present invention to provide a device with which waste, in particular odorous and/or infectious waste arising in the medical sector, can be packaged simply and safely in order to be able to dispose of it without problems.

The invention proposes a device for packaging waste, in particular odorous and/or infectious medical waste, with

a container for receiving the waste contained in a film tube, the container having a container opening,

a headpiece that can be placed on the container and has a holder for the film tube,
a closing device for the film tube,
- a separating device for the film tube, as well as
a locking element for the headpiece.

The essential feature of the present invention is that the waste is not taken up directly from the container, but is packed individually or in a large number in the film tube. The head piece that can be placed on the container takes up the film tube, which is closed in the area of its container-side end before being removed from the holder and inserted into the container, so that a sack-like structure is created into which the waste can be placed. The film tube is then closed behind the inserted waste, so that the waste is packed between the front and rear closure of the film tube. The next waste to be produced is placed back into the film tube, and the film tube is closed again behind this last inserted waste, etc. This results in a long tube sausage that is closed between the individual waste and placed in the container. In the sense of

Invention, it is not necessary for each waste to be packaged separately, but it is sensible to proceed in such a way that waste arising during a certain work process is placed in the film tube and then the film tube is closed behind it. If the film tube fills the container with the waste it has collected, the film tube is cut through behind the last closure using the separating device so that the waste in the container can be disposed of with the film tube surrounding it. In order to ensure in particular that the waste can be collected by the device largely odorlessly, a closure element should be provided for the head piece, which takes on the function of a lid for the head piece in the manner of a container lid.

The film tube can be closed in a variety of ways. According to a particularly simple design, the film tube is rotated behind the last waste placed in it, in particular rotated several times, so that an odor- and bacteria-tight separation is ensured between the waste and the tube opening through which the waste is placed into the tube. A welding device could also be provided that welds the tube behind each waste placed in, thus forming individual, precisely formed tube pockets that hold the waste. In addition, it would be possible, for example, to design the closure device for the film tube as a clip or tie device. Particularly when the film tube is welded shut,

0 is to be clipped or snapped shut, it is considered advantageous if the respective closure device is arranged inside the container and can be operated from outside the container.

It is particularly intended that the container is pot-shaped, i.e. the container edge surrounding the container opening and thus also the area of the head piece that can be placed on the container edge

circular shape.

According to a special embodiment, it is provided that the head piece has a lid-shaped base for placing on the container, whereby the base is provided with an opening for the film tube to be pushed through. The head piece should have the receptacle for the film tube on the side facing away from the container. A specific design provides that the receptacle of the head piece has two ring elements arranged concentrically to the opening in the base, which hold a ring-shaped cartridge for the film tube between them. The film tube is packed tightly folded in the cartridge, for example a film tube with a length of more than 100 m. When inserting a new cartridge, the beginning of the tube is first pulled out of the cartridge and closed, then the closed area is pushed through the opening in the base of the head piece, thus preparing the device for receiving the waste. The cartridge is advantageously provided with an annular gap on its side facing away from the container for dispensing the film tube. The size of the annular gap is appropriately selected so that the foil tube must be pulled out of the cartridge against a slight resistance.

A favorable design of the device provides that the opening in the base of the head piece can be closed with a cover. In particular, it is intended to provide an elastic cover through which the film tube with the waste is pushed through, with the cover clamping the film tube after it has been pushed through. The cover can, for example, consist of elastic elements that extend radially and essentially pass through the opening in the base of the head piece.

According to a special embodiment of the invention, it is provided that the closing device for the film tube has a cover element that can be placed on the cartridge in a sealing and rotationally fixed manner. The cover element not only serves the

Not only does it have the function of ensuring a certain odor-tight seal to the outside, but due to the fact that the cover element can be placed on the cartridge in a rotationally fixed manner, the film tube can be twisted using the cover element so that a closure is created behind the last waste put into the film tube. The sealed and rotationally fixed connection can be created particularly easily in the area of the cover element by the cartridge having a conical effective surface in the area of its inner upper end facing the cover element and/or the cover element having a conical effective surface in the area of its end facing the inner upper end of the cartridge. When the cover element is inserted into the space enclosed by the cartridge, the film tube is clamped between the cover element and the conical effective surface of the cartridge, so that when the cover element is rotated, the cartridge and thus also the clamped film tube are also twisted. The arrangement of the conical effective surface on the cover element and/or the cartridge is arbitrary. In order to be able to introduce the torque forces particularly easily into the cover element, it should be provided with a groove on the outside.

According to a further preferred design, a rotating insert is mounted in the lid element, which is provided with a cutting knife on the side facing the cover. As soon as the container is filled with the waste in the film tube, the film tube can be easily cut off along the circumference of the tube in the area of the cartridge or the lid element using the rotating knife, so that after opening the device for packaging waste, i.e. removing the head piece from the container, the container can be emptied. In order to be able to separate the film tube safely, the rotating insert is advantageously provided with a piercing attachment for the film tube on the side facing the cover, with the cutting knife being arranged between the piercing attachment and the lid element. When the rotating insert is rotated, the tip of the piercing attachment pierces the film tube and when the insert is rotated further, the film in this area is

hose is moved in the direction of the connection of the piercing attachment on the rotating insert, whereby the film hose comes into contact with the cutting blade and is severed as the insert continues to rotate. The insert core can then be twisted particularly easily if it is provided with an external grip bar.

In terms of construction, the device is designed in such a way that the head piece is provided with an inward-facing ring attachment that covers the cartridge on the side facing away from the container and that is covered by the lid element. This results in a certain guidance of the lid element relative to the head piece. In order to ensure complete odor sealing of the container from the outside, a lid should also be provided to cover the head piece. The lid is expediently connected to the head piece in a pivoting manner.

With a device designed in this way, after opening the lid, the lid element placed on the cartridge can be removed and the waste can be fed into the film tube in the area below the cover. The lid element is then placed on the cartridge, clamping the film tube between itself and the cartridge and then the lid element is twisted, whereby the film tube is closed behind the last waste inserted by twisting. The twisting of the film tube is supported by the cover, which virtually clamps the film tube between the individual, flexible cover elements. The lid is then closed to cover the head piece until 0 new waste is generated and can be fed into the device in the manner described above.

Further features of the invention are shown in the subclaims, the description of the figures and in the figures themselves, it being noted that all individual features and all combinations of individual features are essential to the invention.

In the figures, the invention is illustrated in an embodiment

- 7 for example, but are not limited to them.

It shows:

Figure 1 is a simplified representation of the inventive

Device for packaging waste, in a longitudinal center section,
Figure 2 shows a detailed view of the device in the area of

Headpiece, in longitudinal center section,

Figure 3 is a view A of the cover element according to Figure 2 and Figure 4 is a view B of the cover element according to Figure 2.

The device shown in Figure 1 is used for packaging odorous and infectious medical waste. The device has a conventional bucket-like container 1 onto which a head piece 2 can be placed, which closes the container 1.

In detail, the container edge 4 surrounding the container opening 3 has a circular shape. A lid-shaped base 5 of the head piece 2 can be placed on the container edge 4. The base 5 is provided with an opening 7 arranged concentrically to the longitudinal axis 6, which connects the interior 8 of the head piece 2 with the interior 9 of the container 1. On the underside of the base 5, thus the area of the base 5 facing the container 1, a panel 10 is connected to the base 5. The panel 10 has individual, flexible panel segments 11 running in the direction of the longitudinal axis 6, which allow the waste to pass through from the interior 8 of the head piece into the interior 9 of the container 1 despite the cross-section of the opening 7 being reduced by the panel 10.

The base 5 of the head piece 2 continues in an outer ring wall 12 and a shorter inner ring wall 13. In the space between the two ring walls 12 and 13, an annular cartridge 14 is inserted, which contains a folded film tube 15 in the tube, for example one made of HDPE, thickness 0.025 mm, long, for example a

Length of more than 100 m. The cartridge 14 is closed at the top by means of an annular plate 16, which leaves an annular gap 18 between itself and the inner cartridge wall 17. The film tube 15 can be pulled out of the cartridge 14 through this annular gap 18. The ring thickness of the cartridge 14 determined by the inner cartridge wall 17 and the outer cartridge wall 19 is less than the ring thickness between the outer ring wall 12 and the inner ring wall 13 of the head piece 2. The cartridge 14 can therefore be rotated relative to the head piece 2.

The head piece 2 is provided in the area of its upper end with an inwardly directed ring extension 20 which covers the cartridge 14 on its side facing away from the container 1 and which can be plugged onto the outer ring wall 12. In the ring extension 20, a cover 21 covering it is pivotally mounted in the bearing 22.

As can be seen from the illustration in Figure 1 and in detail in Figures 2 to 4, the device has a cover element 23 which serves the purpose of clamping the film tube 15 between the cover element 23 and the upper end of the inner cartridge wall 17 so that the cartridge 14 can be rotated. The cover element 23 is designed as a ring part with an external corrugation 41, furthermore with an axial ring extension 24, the free, lower end of which is provided on the side facing the inner cartridge wall 17 with a conical active surface 25 which interacts with a conical active surface 26 of the inner cartridge wall 17 which is arranged in the region of the upper end of this cartridge wall 17. The other ring extension 27 of the lid element 23 is directed essentially radially and covers the ring extension 20. In the area of the projecting, circumferential extension 28 of the ring extension 24 of the lid element 23, a rotatable insert 29 is clipped into the lid element 23. This has a handle bar 30 on its side facing away from the container 1, i.e. on the outside, for rotating the insert 29. As can be seen in particular from the illustration in Figures 2 and 4,

a piercing attachment 32 is connected to the flat inner surface 31 of the insert 29, which is positioned essentially tangentially in the area of the separating surface of the rotating insert 29 and the cover element 23. The connection area of the piercing attachment 32 with the insert 29 is designated with the reference number 33, and the pointed end of the piercing attachment is designated with the reference number 34. In the area of the end 33 of the piercing attachment 32, a separating knife 35 is placed between the latter and the rotating insert 29.

Using the device described above, the waste is packaged as follows: After emptying the container 1, the head piece 2 is placed on the container and the lid 21 is opened, and the lid element 23 with the rotating insert 29 is removed from the cartridge 14. The end of the film tube 15 protruding from the cartridge 14 is then grasped and closed, for example by providing it with a knot or the clip element 36 shown in Figure 2. The waste is then placed in the film tube closed at the bottom, for example the waste part 37 shown in Figure 2, which can be a wound dressing, a diaper, etc. The waste part 37 is placed in such a way that when it is placed on the clip end of the film tube, it is fed into the container 1 together with the relevant area of the film tube 15 past the flexible aperture segments 11 of the aperture 10. Of course, if several waste parts 37 are generated, they can be fed into the film tube at the same time and transferred past the aperture 10 into the container 1. If it is not possible to predict when the next waste part 37 is to be fed into the container, the cover element 23 with the rotating insert 29 is placed on the cartridge 14, whereby the film tube 15 is clamped in the area of the conical active surfaces 25 and 26 of the cover element 23 and cartridge 14. When the cover element 23 is rotated, for example by two full circles, the area of the film tube 15 facing the cover element 27 and, due to the clamping, the cartridge 14 are also rotated accordingly, so that as a result in the area of the aperture

- 10 -

10 results in a twisting of the film tube 15 relative to the area of the film tube 15 located in the container 1 by two circular rotations, whereby the film tube 15 is closed behind the waste part 17 last fed into the film tube 15. If the device is not required for the next time, the lid 21 is closed, as shown in Figure 1. If a waste part 37 is to be packaged again, the corresponding step follows, i.e., opening the lid 21, removing the lid element 23 with the rotating insert 29, inserting the waste part 37 into the film tube 15, whereby the waste part 37 and the area of the film tube 15 facing it are pressed through the cover 10 into the container 1, then the lid element 23 with the rotating insert 29 is placed back on the cartridge 14 and the insert 29 is rotated and the lid 21 is folded into its closed position.

If the container 1 is filled with waste, it is necessary to separate the film tube 15 in the area of the lid element 23.

This is done with the lid element 23 in place by grasping and turning the rotating insert 29 in the area of the handle bar 30. Due to the tangential arrangement of the piercing attachment, this means that the latter pierces the film tube with its tip 34, whereby when the insert 29 is rotated further, the piercing attachment 32 is pierced further through the film tube 15 and this comes into contact with the cutting blade 35, whereby when the rotating insert 29 rotates a full circle, the film tube 15 is completely severed. After removing the head piece 2 from the container 1, the latter can be emptied in the usual way.

In Figure 1, the reference number 38 designates a welding element that may be present and is stored in the base 5. It has a welding tongs 39 consisting of two legs, with only one leg 40 being shown. The welding element 38 located in the container 1 is operated from outside the container 1. The electrical connections to the welding element 38

are not illustrated. If such a welding element 38 is present, the cover element 32 can be omitted. In this case, it is advisable to also integrate the separating element into the welding element 38.
