An outer wall (28) surrounds the central tubular portion and a cassette bottom (30) extends between and connects the outer wall and the central tubular portion. The outer wall, the cassette bottom and the central tubular portion cooperate to define an interior area (32) that surrounds the central tubular portion. A length of flexible tubing (34) is positioned in the interior area. The cassette bottom includes first registration features (42) and a cover (36) is coupled to the body and at least partially overlies the interior area, the cover defining second registration features (44) matingly engageable with the first registration features so that cassettes can be stacked one-on-top-of-the-other with the cooperation of the first and second registration features (42, 44) preventing successively stacked cassettes from shifting relative to one another.
Description
Cassette for Dispensing Flexible Tubing Therefrom Field of the Invention The present invention is generally related to cassettes having plastic tubing therein used in the disposal of waste products such as soiled diapers and is more particularly related to said cassettes having registration features thereon for more efficient stacking as well as to aid in the prevention of improper installation of the cassettes into a receptacle operable therewith.
Background of the Invention Historically, waste materials such as soiled diapers were disposed of by simply placing them in the trash, however, this presented sanitary and odor problems.
Moreover, with regard to soiled diapers, these are typically disposed of, albeit temporarily, in the area where the child is changed. Usually this is the nursery where the child sleeps and spends a considerable amount of time. As such, maintaining a sanitary and relatively odor free environment is important.
A number of systems have been developed to address the above-described disposal and sanitary issues associated with soiled diapers. One such disposal system is referred to as the Diaper Genie manufactured by Playtex Products, Inc. of Westport, CT. This system employs a receptacle having an interior waste storage area and an interior area for receiving and retaining a cassette having a length of plastic tubing stored therein and dispensable therefrom. When a soiled diaper is inserted into the receptacle, it is pushed through an opening in the cassette where the soiled diaper is encased and substantially sealed within the plastic tubing. Once the quantity of plastic tubing in the cassette has been exhausted, the cassette is removed from the receptacle and replaced with a new cassette.
A problem that can sometimes occur when placing the cassette in the receptacle is that the cassette can inadvertently be installed upside down. When this occurs and a soiled diaper is inserted into the receptacle through the cassette, the diaper is exposed to parts of the cassette prior to encountering the plastic tubing. This creates potential sanitary problems. In addition, an overabundance of plastic tubing can be dispensed resulting in the cassette having to be prematurely replaced. Moreover, the amount of plastic tubing remaining in the cassette is not readily ascertainable.
Another difficulty associated with the above-described cassettes arises from the fact that they are sold in stores as replacements for exhausted cassettes and therefore must be

Another difficulty associated with the above-described cassettes arises from the fact that they are sold in stores as replacements for exhausted cassettes and therefore must be
2 shipped in boxes to the various retail outlets. In order to be shipped and sold, the cassettes are generally stacked in the boxes and then stacked on top of one another on store shelves.
The configuration of the cassettes has made them susceptible to toppling or shifting relative to one another when stacked on the store shelves. The cassette configuration has also made them difficult to stack so packing them into boxes for shipment is less than optimal.
Based on the foregoing, it is the general object of the present invention to provide a cassette and a cassette and receptacle system that improves upon or overcomes the problems and drawbacks associated with known cassettes and receptacles.
Summary of the Invention The present invention resides in one aspect in a cassette for dispensing flexible tubing.
The cassette includes a cassette body having a central tubular portion defining an aperture extending therethrough, through which, during use, waste materials such as soiled diapers are passed. The cassette includes an outer wall that surrounds the central tubular portion with a cassette bottom extending between and connecting the outer wall and the central tubular portion. The cooperation of the outer wall, the cassette bottom and the central tubular portion defines an interior area into which a length of flexible tubing is positioned to be dispensed from the cassette. A cover is coupled to the cassette body and at least partially overlies the interior area.
The cassette bottom includes first registration features located on an outwardly facing surface with the cover defining second registration features also located on an outwardly facing surface. The first registration features defined by the cassette bottom and the second registration features defined by the cover are matingly engageable with one another so that cassettes can be stacked one-on-top-of-the-other with the cooperation of the first and second registration features preventing successively stacked cassettes from shifting relative to one another.
In an embodiment of the present invention, one of the first and second registration features includes at least one and preferably a plurality of outwardly projecting protuberances with the other of the first and second registration features including at least one and preferably a plurality of recesses complementarily shaped to engage the protuberances. In a preferred embodiment of the present invention, the cassette bottom and the cover are each circular with the plurality of protuberances being defined by a plurality of raised bumps projecting outwardly from one of the cassette bottom and the cover, the raised bumps being radially and circumferentially spaced there around. Likewise, the recesses are radially and

Based on the foregoing, it is the general object of the present invention to provide a cassette and a cassette and receptacle system that improves upon or overcomes the problems and drawbacks associated with known cassettes and receptacles.
Summary of the Invention The present invention resides in one aspect in a cassette for dispensing flexible tubing.
The cassette includes a cassette body having a central tubular portion defining an aperture extending therethrough, through which, during use, waste materials such as soiled diapers are passed. The cassette includes an outer wall that surrounds the central tubular portion with a cassette bottom extending between and connecting the outer wall and the central tubular portion. The cooperation of the outer wall, the cassette bottom and the central tubular portion defines an interior area into which a length of flexible tubing is positioned to be dispensed from the cassette. A cover is coupled to the cassette body and at least partially overlies the interior area.
The cassette bottom includes first registration features located on an outwardly facing surface with the cover defining second registration features also located on an outwardly facing surface. The first registration features defined by the cassette bottom and the second registration features defined by the cover are matingly engageable with one another so that cassettes can be stacked one-on-top-of-the-other with the cooperation of the first and second registration features preventing successively stacked cassettes from shifting relative to one another.
In an embodiment of the present invention, one of the first and second registration features includes at least one and preferably a plurality of outwardly projecting protuberances with the other of the first and second registration features including at least one and preferably a plurality of recesses complementarily shaped to engage the protuberances. In a preferred embodiment of the present invention, the cassette bottom and the cover are each circular with the plurality of protuberances being defined by a plurality of raised bumps projecting outwardly from one of the cassette bottom and the cover, the raised bumps being radially and circumferentially spaced there around. Likewise, the recesses are radially and
3 PCT/US2008/062367 circumferentially spaced around the other of the cassette bottom and the cover. Each of the recesses is complimentarily shaped to engage at least one of the protuberances when cassettes are successively stacked one-on-top-of-the-other.
In another embodiment of the present invention the first registration features are defined by one or more first steps, each having a first raised portion and a corresponding first recessed portion. The second registration features are defined by one or more second steps each having a second raised portion and a corresponding second recessed portion. The first raised portions are matingly engageable with the second recessed portions and the first recessed portions are matingly engageable with the second raised portions so that when cassettes are stacked one on top of the other, the first steps of one of the cassettes engage the second steps of another of the cassettes thereby minimizing relative movement between successively stacked cassettes.
In still another embodiment of the present invention, the first registration features include a first undulating surface formed by the cassette bottom and the second registration features include a second undulating surface formed by the cover. The first and second undulating surfaces are matingly engageable with one another so that when cassettes are stacked one on top of the other, the first undulating surface of one of the cassettes engages the second undulating surface of another of the cassettes thereby minimizing relative movement between successively stacked cassettes. Preferably, in this embodiment of the present invention, a lip extends along a peripheral surface defined by the cover so that an outer periphery defined by the cassette bottom is slidably engageable with the lip when one cassette is positioned on top of another cassette.
In yet another embodiment of the present invention, the cover and the cassette bottom are each substantially circular with one of the first and second registration features including a plurality of outwardly projecting ribs and the other of the first and second registration features including a plurality of recesses. When two or more cassettes are stacked on top of one another, the ribs defined by one cassette are matingly receivable in the recesses defined by another cassette. Preferably, and in addition to the ribs and recesses described above, the cassette bottom and the cover each define an outer peripheral edge with one of the cassette bottom and the cover defining an annular raised area positioned internally of the peripheral edge and the other of the cassette bottom and the cover defining an annular recessed portion positioned internally of the peripheral edge. The annular raised portion is slidably engageable with the annular recessed portion when cassettes are successively stacked on top of one another.
In another embodiment of the present invention the first registration features are defined by one or more first steps, each having a first raised portion and a corresponding first recessed portion. The second registration features are defined by one or more second steps each having a second raised portion and a corresponding second recessed portion. The first raised portions are matingly engageable with the second recessed portions and the first recessed portions are matingly engageable with the second raised portions so that when cassettes are stacked one on top of the other, the first steps of one of the cassettes engage the second steps of another of the cassettes thereby minimizing relative movement between successively stacked cassettes.
In still another embodiment of the present invention, the first registration features include a first undulating surface formed by the cassette bottom and the second registration features include a second undulating surface formed by the cover. The first and second undulating surfaces are matingly engageable with one another so that when cassettes are stacked one on top of the other, the first undulating surface of one of the cassettes engages the second undulating surface of another of the cassettes thereby minimizing relative movement between successively stacked cassettes. Preferably, in this embodiment of the present invention, a lip extends along a peripheral surface defined by the cover so that an outer periphery defined by the cassette bottom is slidably engageable with the lip when one cassette is positioned on top of another cassette.
In yet another embodiment of the present invention, the cover and the cassette bottom are each substantially circular with one of the first and second registration features including a plurality of outwardly projecting ribs and the other of the first and second registration features including a plurality of recesses. When two or more cassettes are stacked on top of one another, the ribs defined by one cassette are matingly receivable in the recesses defined by another cassette. Preferably, and in addition to the ribs and recesses described above, the cassette bottom and the cover each define an outer peripheral edge with one of the cassette bottom and the cover defining an annular raised area positioned internally of the peripheral edge and the other of the cassette bottom and the cover defining an annular recessed portion positioned internally of the peripheral edge. The annular raised portion is slidably engageable with the annular recessed portion when cassettes are successively stacked on top of one another.
4 The present invention resides in a second aspect in a cassette for dispensing flexible tubing and a receptacle for receiving the cassette. The cassette is configured essentially as described above with the exception that for this embodiment it is not necessary for the cover to include registration features. Accordingly, the cassette includes a cassette body having a central tubular portion defining an aperture extending therethrough. An outer wall surrounds the central tubular portion and a cassette bottom extends between and connects the outer wall and the central tubular portion. The outer wall, the cassette bottom and the central tubular portion cooperate to define an interior area that surrounds the central tubular portion and into which a length of flexible tubing is positioned. A cover is coupled to the body and at least partially overlies the interior area so that the flexible tubing can be dispensed through an opening defined by an inner peripheral edge of the cover and the central tubular portion. The cassette bottom includes first registration features. While the cover has been described as not necessarily including registration features, this embodiment of the present is not limited in this regard as the cover can include registration features mating engageable with the registration features defined by the cassette bottom so that the registration features of successively stacked cassettes engage one another.
The receptacle includes an opening sized at least to receive the cassette and defines alignment features matingly engageable with those defined by the cassette bottom thereby minimizing the likelihood of the cassette being improperly installed within the receptacle.

Detailed Description of the Preferred Embodiment of the Present Invention As shown in FIGS. 1 and 2, a cassette for dispensing plastic tubing is generally designated by the reference number 20. The cassette includes a cassette body generally designated by the reference number 22. The cassette body is defined by a tubular central portion 24 having an aperture 26 extending therethrough. An outer wall 28 surrounds the tubular central portion 24 and is connected thereto by a cassette bottom 30.
The tubular central portion 24, the outer wall 28 and the cassette bottom 30 cooperate together to define an interior area 32 into which a length of flexible tubing 34 is operably positioned. A cover generally designated by the reference number 36 is attached to the body 22.
The cover 36 has an interior peripheral edge 37 that defines an opening 38 extending through the cover. The opening 38 is sized to form a gap 40 between the tubular central portion 24 and the interior peripheral edge 37 of the cover 24. While the cassette 20 has been shown in the illustrated embodiment as being cylindrical, the present invention is not limited in this regard as other shapes such as squares, rectangles, ovals, and the like, or combinations of these shapes, can be substituted without departing from the broader aspects of the present invention.
Still referring to FIGS. 1 and 2, the cassette bottom 30 defines first registration features, shown in the illustrated embodiment as a plurality of recesses 42 radially spaced around an outer periphery of the cassette bottom. Similarly, the cover 36 defines second registration features, shown in the illustrated embodiment as a plurality of protuberances or raised bumps 44. The recesses 42 and the raised bumps 44 are complimentarily shaped relative to one another so that when cassettes 20 are stacked one-on-top-of-the-other, the raised bumps 44 of one cassette matingly engage the recesses 42 of the next successive cassette, thereby minimizing the potential for relative movement between successively

Detailed Description of the Preferred Embodiment of the Present Invention As shown in FIGS. 1 and 2, a cassette for dispensing plastic tubing is generally designated by the reference number 20. The cassette includes a cassette body generally designated by the reference number 22. The cassette body is defined by a tubular central portion 24 having an aperture 26 extending therethrough. An outer wall 28 surrounds the tubular central portion 24 and is connected thereto by a cassette bottom 30.
The tubular central portion 24, the outer wall 28 and the cassette bottom 30 cooperate together to define an interior area 32 into which a length of flexible tubing 34 is operably positioned. A cover generally designated by the reference number 36 is attached to the body 22.
The cover 36 has an interior peripheral edge 37 that defines an opening 38 extending through the cover. The opening 38 is sized to form a gap 40 between the tubular central portion 24 and the interior peripheral edge 37 of the cover 24. While the cassette 20 has been shown in the illustrated embodiment as being cylindrical, the present invention is not limited in this regard as other shapes such as squares, rectangles, ovals, and the like, or combinations of these shapes, can be substituted without departing from the broader aspects of the present invention.
Still referring to FIGS. 1 and 2, the cassette bottom 30 defines first registration features, shown in the illustrated embodiment as a plurality of recesses 42 radially spaced around an outer periphery of the cassette bottom. Similarly, the cover 36 defines second registration features, shown in the illustrated embodiment as a plurality of protuberances or raised bumps 44. The recesses 42 and the raised bumps 44 are complimentarily shaped relative to one another so that when cassettes 20 are stacked one-on-top-of-the-other, the raised bumps 44 of one cassette matingly engage the recesses 42 of the next successive cassette, thereby minimizing the potential for relative movement between successively
6 stacked cassettes. While a plurality of recesses 42 and raised bumps 44 have been shown and described, the present invention is not limited in this regard as any number of recesses and raised bumps, even a single recess and raised bump can be employed. In addition, while the recesses and raised bumps, 42 and 44 respectively, have been shown as all being the same size and shape, the present invention is not limited in this regard as different shapes, different sizes, and combinations of different sizes and shapes can be employed without departing from the broader aspects of the present invention.
As shown in FIGS. 3 and 4, an embodiment of the cassette 20 is shown therein and generally referred to by the reference number 120. The cassette 120 is similar in many respects to the cassette 20, accordingly like elements will be given similar reference numbers preceded by the numeral 1. The cassette 120 differs from the cassette 20 in that instead of recesses 42 and raised bumps 44, the first and second registration features are in the form of first and second steps, 142 and 144 respectively. Each of the first steps 142 is formed by a raised portion 146 and an adjacent recessed portion 148. Likewise, each of the second steps 144 is formed by a raised portion 150 and a corresponding recessed portion 152.
Accordingly, when two or more cassettes 120 are stacked one-on-top-of-the-other, the first and second steps, 142 and 144 respectively, matingly engage one another.
As shown in FIGS. 5 and 6, an embodiment of the cassette 20 is shown therein and generally referred to by the reference number 220. The cassette 220 is similar in many respects to the cassette 20, accordingly like elements will be given similar reference numbers preceded by the numeral 2. The cassette 220 differs from the cassette 20 in that instead of recesses 42 and raised bumps 44, the first and second registration features are in the form of first and second undulating surfaces, 242 and 244 respectively. Each of the first and second undulating surfaces, 242 and 244 respectively, is formed by a by a series of successive peaks and valleys which in the illustrated embodiment vary in a sinusoidal pattern.
Accordingly, when two or more cassettes 220 are stacked one-on-top-of-the-other, the peaks of one of the first and second undulating surfaces, 242 and 244 respectively, matingly engage the valleys of the other of the first and second undulating surfaces thereby causing successively stacked cassettes to nest into one another. The cover 236 of the cassette 220 includes a lip 243 extending around an outer peripheral edge of the cover. When two or more cassettes 220 are stacked on top of one another, the lip 243 slidingly engages the outer wall 228 [not labeled on Figure] of the next successively stacked cassette thereby minimizing or preventing the potential for relative movement between the cassettes.
