CASSETTE AND APPARATUS FOR PACKING DISPOSABLE OBJECTS INTO AN ELONGATED TUBE OF FLEXIBLE MATERIAL
A cassette (3) for dispensing bags from an elongated tubing (32) comprising an annular receptacle (38) accommodating a length of tubing (32) in an accumulated condition. An annular opening at an upper end of the annular receptacle (38) is for dispensing the tubing (32). The annular receptacle (38) defines a central opening (34) through which a knotted end (40) of the tubing (32) passes to form a bag supported by the annular receptacle (38) with disposable objects passing through the circular central opening (34) to be received in the bag, and a clearance (41) only at a bottom of the central opening (34).
The present application relates to an apparatus for packaging disposable material or objects into a tube of flexible plastic film material. More specifically, the invention relates to an apparatus for use to package waste material, for example babies' disposable diapers, or any other kind of appropriate objects or material, into a tube of flexible plastic film material and to store the so packaged waste material in a hygienic and a substantially odor-free manner, until it is collected.
BACKGROUND OF THE ARTKnown apparatuses of the above-mentioned type generally comprise a container having an open or openable upper portion in which the waste to be disposed of may be inserted and a bottom portion in which the disposed waste is stored. A ring-shaped cassette is mounted in the upper portion of the container, and contains, in a pleated form, a tube of flexible plastic film material which is formed into an elongated tube which is knotted at a bottom end and into which the waste material may be inserted and temporarily stored.
In use, the waste to be disposed of is inserted into the tube at the upper portion of the container and the tube and waste are then pushed through the open center of the cassette towards the bottom portion of the container for storage purposes. Closeable means are also provided for closing the tube below the cassette and thus preventing bad odors from escaping from the tube during storage.
In Canadian Patent No. 1,298,191, these closeable means are disclosed as a core that can be turned by a lid about a cylinder in order to twist the tube at regular intervals to form successive “pouches” that are kept sealed while they are stored.
In Canadian laid-open Application No. 2,383,799, a squeezing device is mounted in the container below the cassette to pull the tube from the cassette and move it down together with the objects inserted into the container. This squeezing device comprises a pair of opposite rotatable members between which the tube is inserted. The rotatable members have a plurality of opposite bars extending transversely to the tube in order to squeeze the tube, keep it closed until other objects to be disposed of are inserted into the upper portion of the container, and pull it down to move the plastic film forming the tube and the objects contained therein towards the bottom portion of the container for storage purpose. Actuation of the rotatable members in unison and in opposite direction to achieve the requested squeezing, closing and pulling down of the plastic film tube is preferably obtained by actuation of a lever that is part of the container.
In Canadian laid-open Application No. 2,441,837, a plunging device is provided to compress the object to be disposed of, and push it into the tube and to the bottom part of the container. The plunging device includes two arms with pivoting flaps attached thereto and opposing pivotable slides.
All of these prior art devices have several disadvantages. Their mechanisms have many parts and are prone to breakage. These devices are also not user-friendly and difficult to understand the operation thereof when first purchased. They are costly to fabricate and they utilize excess film from the cassettes, adding to the cost of use. Some also do not effectively contain the odors of the disposed material. Some cause confusion in their installation, causing improperly oriented cassettes and contamination of the cassette walls.

Referring to
The top portion 14 and bottom portion are locked together with a mechanism such as a push button latch (not shown) received in eyelet 20, located opposite of the hinge member 16. Upon actuation of the push button, the top portion 14 and bottom portion are disconnected and can be pivoted apart about the hinge member 16 to provide access to the enclosure 18, for example to empty the bin 12.
The top portion 14 defines an opening 22 for receiving disposable objects therethrough. The bin 12 further comprises a lid 24 hingedly connected to a ring 25, for instance in the shape of a funnel (hereinafter funnel 25), although multiple shapes are considered such as a flat ring, as long as the ring forms an opening guidance. The funnel 25 is mounted to the top portion 14 such as to selectively open and close access to the opening 22 through pivoting motion of the lid 24. Although in the embodiment shown the apparatus has a generally circular opening 22, the bin 12 is not limited to circular openings and could function with openings of different shapes.

Referring to
Referring to FIGS. 1 and 3A-3C, the apparatus 10 further includes a closing mechanism 50 whose purpose is to provide access to the flexible tubing 32 extending therebelow and preventing odors from escaping from the flexible tubing 32. In one form of use, it permits the disposable objects to push down against the bottom of the tubing 32 (at the knot 40) to draw out loose flexible tubing from the receptacle 38 of the cassette 30. One aspect of note is that the flexible tubing 32 passes over receptacle 38 and the closing mechanism 50, thereby isolating the receptacle 38 and the mechanism 50 from the disposable objects to be packaged, reducing the need for constant cleaning of the walls defining the opening 34 and the mechanism 50. In this respect, one will appreciate that one of the preferred uses for the apparatus 10 is the disposal of baby diapers.
The closing mechanism 50 comprises a fixed portion 52, which comprises a generally “C”-shaped member rigidly connected to the wall 44 of the holder 26. Alternate types of connections are also possible for the fixed portion 52, including connection to an additional support member connected to the holder 26 or to another part of the top portion 14. The curved fixed portion 52 defines a rounded apex 54 which projects into the opening 22, as can be seen in
The movable portion 58 of the closing mechanism 50 is also generally “C”-shaped in cross-section and is biased against the fixed portion 52 in a closed position shown in
The movable portion 58 is slidingly supported by a pair of spaced-apart, generally vertical walls 64 (only one of which is shown in
The movable portion 58 includes aligned sliding members 66A extending therefrom and engaging the slots 66, such that the movable portion 58 is slidingly movable along an angular direction defined by the slots 66, and thus along direction A. The movable portion 58 can move between a closed position, as illustrated in
It is of particular importance that the cassette 30 be installed in the appropriate orientation. In the appropriate orientation, as illustrated in
As is clearly seen in
Alternately, the fixed portion 52 can be replaced by a portion movable opposite of the movable portion 58, the two being biased together in the closed position. Such a configuration could be, for example, two sliding members symmetrical with respect to one another about a vertical axis defined at the point of contact therebetween, such as two “C”-shaped members similar in configuration to the movable member 58 shown, two rollers, etc., which are slidable away from each other upon downwardly pushing an object thereon, and are biased together for example by being interconnected by one or a plurality of springs. However, such a mechanism includes additional parts.
In order to assist the user in correctly placing the disposable object in the tubing 32, the apparatus 10 advantageously has the funnel 25 removably installed over the cassette 30, providing a downward shape around the openings 22,34, which creates a funnel effect and guides the user's hand. A handle 68 is provided to remove the lid 24/funnel 25 assembly.
Referring to
In order to prepare the apparatus 10 for use, and with reference to
Alternately, the tube end with the knot 40 could be pulled down to the bottom of the bin 12, for example by pivoting and opening the top portion 14 such as to gain access to the enclosure 18, and pulling the tube end with the knot 40 through the closing mechanism 50 and beyond to the bottom of the bin 12. The top portion 14 is then re-engaged with the bottom portion, and the lid 24/funnel 25 assembly is reinstalled on the top portion 14. Accordingly a length of empty flexible tubing 32 extends to the bottom and is now ready to receive disposable objects therein. Therefore, the film material is not pulled from the cassettes 30 as disposable objects are placed into the tube.
In use, when a disposable object needs to be packaged, the lid 24 of the apparatus 10 is lifted, thereby providing access to the opening 22. The disposable object to be packaged is placed into the opening 22 (in this case, the cassette 30 of flexible tubing 32 surrounds the object). The receiving surfaces 56,62 of the fixed and movable portions 52,58 of the closing mechanism 50 biased together in the closed position form a trough which directs the disposable object in the hand of a user person toward a contact region therebetween.
The user person pushes the disposable object in a downward direction, gradually opening the movable portion 58, as is shown in
Once the disposable object passes beyond the apex 60 of the movable portion 58, the user person releases the disposable object and withdraws his or her hand. The movable portion 58, under the action of the spring 67, rapidly returns to the closed position of
It is pointed out that different configurations of the cassette are considered. For instance, clearances of different shapes can be used instead of a chamfer. The use of a chamfer shape does not substantially reduce the volume of the receptacle 38 of the cassette 30, thereby generally preserving the quantity of tubing 32 received in the cassette 30.
In an alternative embodiment illustrated in
For each new disposable object to be packed, the process is repeated, each time either dropping the disposable object within the already drawn length of flexible tubing 32 within the enclosure 18, or drawing out an additional length of flexible tubing 32 from the cassette 30 to accommodate another disposable object as the disposable object moves down into the tube inside the apparatus 10, until the enclosure 18 is full, containing an object-filled segment of flexible film tubing 32. In this case, the top portion 14 is pivoted away from the bottom portion. The flexible tubing 32 is then cut, for example by using the cutting tool 70 provided, and then tied to form a substantially sealed pouch which can be removed from the bin 12. The top portion 14 is pivoted back into engagement with the bottom portion to use the apparatus 10 again as described above.
In another embodiment of the apparatus 10 using the cassette 30 of
In another embodiment illustrated by
Advantages of the apparatus 10 include the use of a wedge-type closing mechanism 50 of simple construction with few parts to seal the flexible tubing 32. The cassette configurations ensure that the cassette 30 is properly installed in the holder 26, thereby preventing contamination of the walls of the cassette (and the hands of the user person) as the properly installed cassette is mostly covered by the tubing 32 as is shown in
