In WO 02/100723 A1 a funnel-shaped sleeve piece is provided for a waste storage device which serves to receive a film as a tubular endless liner. The sleeve piece has a conically outwardly opening neck from which extends a cylindrical portion for receiving the endless liner. A package encloses the sleeve piece and compacts the endless liner stored on the cylinder portion.

A cassette for storing a flexible tubular endless liner is known from EP 0 353 922 B1. The cassette consists of a cylindrical tube, open at the top and bottom, and a housing arranged radially around the tube. The housing is bounded at the bottom by a bottom and can be closed at the top with a snap-on cap. The endless liner is tightly layered in the housing. Between the cap and tube remains a gap through which the endless liner is guided into the tube.

The device according to EP 1 169 247 B1 serves for the storage of waste - eg baby diapers - and consists essentially of a container with a magazine in the form of a double-walled pipe section, in the space between which an endless liner is stored. The magazine is rotatable about a vertical axis to twist the guided into the container working portion of the endless liner, which encloses the waste, odor-tight. The working section to be filled is guided into the container by a bottom feed on the magazine. With increasing fill weight and depression by the user, the bag-shaped working section sinks to the bottom of the container.

The portable device for waste disposal according to US 3,452,368 A also has a container with a magazine in the form of a double-walled pipe section, in the space between which an endless liner is stored. The endless liner is guided by the magazine as nachziehbarer work by a cup-shaped use, at the bottom of which is a closable opening, which is operated when the working section is filled and is to be lowered into the container.

In the company brochure of McLeod Rüssel Filter AG, CH-8610 Uster / Switzerland: "Luwa duct filter housing NSC, assembly instructions - instructions for contamination-free filter change", a filter device and the procedure of a filter change to filter banks are disclosed. When the filter bank is started up, the first assembly and a later filter change take place in the following steps: 1. An unused first filter cell is pushed from a rear-opening first bag, which consists of plastic, into the empty filter housing through an insertion opening and fixed therein. 2. The insertion opening has an alternating collar with two circumferential grooves, being held in the front groove of the bag with its rear, the filter housing facing, now open end by means of a first sealing strip.

3. The bag is rolled up, placed in front of the filter cell, secured with adhesive tape and the maintenance cover put on.

4. After switching the filter bank to the filter change mode, first remove the maintenance cover, roll out the bag, and fix the filter cell. dissolved and finally pulled the spent first filter cell from the filter housing through the insertion opening in the first bag.

5. A wide or double weld is placed between the alternating collar and the outwardly spent first bag with the spent first filter cell therein, which is then cut through, so that the first bag can be removed with its welded content.

6. From the left of the filter bank rest of the first bag, the open bag end is placed around the seated in the front groove first sealing tape. 7. A new, unused second filter cell contained in a second bag is brought to the alternating collar with meanwhile opened rear bag end and this open end of the second bag is fixed in the rear groove of the change collar with a second sealing tape. Thus, the rest of the first bag still hanging on the alternating collar is enclosed by the second sack which has been put over it.

8. By acting as a glove second bag, the remainder of the first bag is released from the front groove and transported along the second filter cell within the second bag to its outwardly facing free end. 9. The second filter cell is out of the second bag through the

Insertion slot pushed into the filter housing and fixed again in it. 10. Thereafter, according to step 3, but continued with the rest of the first bag in the second bag. When changing again with a third filter cell inserted in a third sack, the second sealing strip engaging the remainder of the second sack is displaced from the rear groove of the alternating collar into its front groove in order to clamp the remainder of the second sack here, so that the rear groove for clamping the open end of the third bag is free.

When completely inserted into the container 1 cartridge 2, the bottom 20 of the cartridge 2 is located virtually on the inside 150 of the attached to the container 1 lid 15. Thereafter, the second seal 120 is activated so that between the inner side 101 of the wall 10 and the outside 210 of the first wall 21 of the cartridge 2 in the region of the second seal 120, a seal is formed. The first seal 110 is further deactivated. Dflur 9D: .. Sixth Si _. situation

The third seal 130 is deactivated, whereupon the lid 15 can be removed from the container 1. The first seal 110 remains deactivated and the second seal 120 is activated. Then you reach from the rear end of the container 1 in its passage 19 through the recess 200 to take the beginning 30 of the endless liner 3 and the beginning 30 through the recess 200 in principle axially to the environment U to pull. In this case, the working section 34 is lengthened in accordance with the size of the transfer material 5 to be ejected.

! Fijał _reπ..9E. ..Screens _. situation

This step relates to the embedding of the transfer material 5 in the working section 34 of the endless liner 3. For this purpose, the transfer material 5 is accessed, either by transfer openings in the housing 90 - from within the containment 9 - or via the passage 29 of the cartridge 2 from outside the containment 9 virtually with the everting of the working section 34 into the interior of the containment 9. In both cases, care must be taken to ensure that the endless liner 3 is not damaged, since otherwise a system open to the environment U would arise. For better handling during the discharge process of the transfer material 5, the inner side 221 of the second wall 22 of the cartridge 2 can be used as a supporting surface in order to transfer the transfer material 5 into the working section 34.

FJSyr.en.QF.L Eighth situation

The seals 110-130 remain unchanged from the previous situation. The work section 34 is pulled out of the composite of container 1 and cartridge 2 so far that the transfer product 5 is completely embedded and a second closure 32 can be attached behind it. Distanced from the second closure 32, a first closure 31 takes place again towards the container 1, to which a new working section 34 adjoins, which is available for the next discharge process. The closure tool 43 present on the base plate 40 of the station 4 serves to produce the closures 31, 32, for example by welding to the individual working sections 34. The tool 42 is used to cut off between the two adjacent shutters 31, 32. The Transfergut 5 is tightly enclosed between the first closure 31 and the second closure 32 from the working portion 34 and is ready for disposal or further treatment.

The new first closure 31 at the next working section 34 avoids a system which is open towards the environment U in order to prevent contaminating particles from entering the containment 9 from the outside during the treatment of sterile transfer material 5 or in the treatment of toxic transfer material 5 no particles enter the environment U.

Depending on the application prevails in the containment 9, an overpressure or a negative pressure. In the present sequence of figures, an overpressure is present in the containment 9, since the endless liner 3 with its bag-like working section 34 inflates into the passage 29 of the cartridge 2. If a negative pressure were set in the containment 9, the cartridge 2 could also be pushed by 180 ° into the passage 19 of the container 1. Thus, the cartridge cover 25 would be positioned adjacent to the free end of the wall 10. Due to the negative pressure, the endless liner 3 would now extend with a working portion 34 through the passage 29 of the cartridge 2 in the opposite direction to the containment 9. The beginning 30 of the endless liner 3 can be fixed by means of the separating tool 42 or the closing tool 43 or a clamping element, so that after Nachinnenstülpen the working portion 34 through the passage 29 of the cartridge 2 is avoided. In order to facilitate the discharge process, the inner side 221 of the second wall 22 of the cartridge 2 can again be used as a support surface for guiding the transfer material 5. In both cases, ie with a prevailing in the containment 9 over or under pressure, the endless liner 3 is stored in the magazine space 23 so that a sufficiently high friction torque prevails and thus unwanted, independent removal of the endless liner 3 is avoided by the prevailing pressures. _{Fijayreπ.9G.} , Neunte.Situation

The seals 110-130 remain unchanged from the predecessor situation. After the endless liner 3 has been completely consumed from the magazine space 23 of the cartridge 2, only one remaining portion 37 which is insufficient for another discharge operation remains. The empty cartridge 2 is thus to be replaced by a new full cartridge 2, the full cartridge 2 being stored therein Endless liner 3, the passage 19 of the container 1 is initially approximated coaxially.

Dj9ureπ.9H: .. Zeh.nte. situation

The new full cartridge 2 is partially inserted into the passage 19 of the container 1 until the bottom 20 of the cartridge 2 rests against the cartridge cover 25 of the empty cartridge 2. Thereafter, the first seal 110 is activated, so that between the inner side 101 of the wall 10 and the first wall 21 of the full cartridge 2 in the region of the first seal 110, a seal is formed. The area between the bottom 20 of the full cartridge 2 and the cartridge cover 25 of the empty cartridge 2 is between the first and second seals 110, 120.

First, the second seal 120 is deactivated, the first seal 110 remains activated and the third seal 130 is deactivated. Thus, the empty cartridge 2 from the passage 19 of the container 1 can be removed. An open system towards the environment U is avoided since the new cartridge 2 forms a seal with the activated first seal 110.

First, the first seal 110 is deactivated, the second seal 120 remains deactivated, so that the new cartridge 2 can be pushed completely into the passage 19 of the container 1. The third seal 130 seals the attached to the container 1 lid 15 against the environment U from.

Hgur 9N: Fifteenth. Situation When completely inserted into the container 1 new cartridge 2, the bottom 20 of the cartridge 2 is virtually on the inside 150 of the attached to the container 1 lid 15. Subsequently, the second seal 120 is activated so that between the inside 101 of the wall 10 and the outside 210 of the first wall 21 of the cartridge 2 in the region of the second seal 120, a seal is formed. The first seal 110 is further deactivated, and the third unchanged activated seal 130 seals the lid 15.
