Cassette for dispensing pleated tubing
View Patent ↗A cassette for use in dispensing a pleated tubing within a waste container. The cassette including an annular body having a generally U shaped housing with a central cylindrical core. An annular cover extends inward over the annular body defining a gap. The cover is secured to the body and at least one elongated boss is disposed on an outer surface of the cassette. The elongated boss extends is adapted to receive a key element capable of rotating, or preventing rotation of the cassette.
1. A cassette for use in dispensing pleated tubing, comprising:
an annular body having a generally U shaped housing with a central cylindrical core;
an annular cover extending inward over the annular body defining a gap, the cover being secured to the body; and
at least one elongated boss adapted to receive a key element, the elongated boss disposed on an outer surface of the annular body that extends from a lower end to an upper end of the annular body;
wherein a pair of adjacent elongated bosses define a gap that extends from a lower end to an upper end of the annular body; the gap having a varying width dimension with a narrower upper end than a wider lower end.
2. The cassette recited in claim 1 , wherein the elongated boss has a dimension that is narrower in a radial width than in a length.
3. The cassette recited in claim 1 , wherein the pair of adjacent elongated bosses are disposed around the outer surface of the annular body as sets of adjacent elongated bosses.
4. The cassette recited in claim 1 , wherein the gap is a blind face gap extending over the outer surface of the annular body.
5. The cassette recited in claim 1 , wherein the gap is smaller in width than in a length, wherein the length extends from the lower end to the upper end.
6. The cassette recited in claim 1 , wherein the annular cover has at least one radial gap for rotation or prevention of a rotation.
7. The cassette recited in claim 6 , wherein the at least one radial gap is adapted to receive an indexing mechanism for rotation or prevention of a rotation.
8. The cassette recited in claim 7 , wherein the indexing mechanism is a finger.
9. A cassette for use in dispensing a pleated tubing, comprising:
an annular body having a generally U shaped housing with a central cylindrical core;
an annular cover extending inward over the annular body defining a gap, the cover being secured to the body; and
at least one elongated boss disposed on an outer surface of the annular body that extends from a lower end to an upper end of the annular body, wherein the elongated boss has a dimension that is narrower in a radial width than in a length;
wherein a pair of adjacent elongated bosses define a gap that extends from a lower end to an upper end of the annular body, the gap having a varying width dimension with a narrower upper end than a wider lower end.
10. The cassette recited in claim 9 , wherein the elongated boss is adapted to receive a key and position the cassette at a predetermined height.
11. The cassette recited in claim 9 , wherein the gap is smaller in width than in a length, and wherein the length extends from the lower end to the upper end of the annular body.
12. The cassette recited in claim 9 , wherein the annular cover has at least one radial gap for rotation or prevention of a rotation.
13. The cassette recited in claim 12 , wherein the at least one radial gap is adapted to receive an indexing mechanism for rotation or prevention of a rotation.
14. A cassette for use in dispensing a pleated tubing, comprising:
an annular body having a generally U shaped housing with a central cylindrical core;
an annular cover extending over the annular body defining a gap, the cover being secured to the body; and
at least one elongated boss adapted to receive a key element, the elongated boss disposed on an outer surface of the annular body that extends from a lower end to an upper end of the annular body where the annular cover is provided, and wherein the elongated boss has a dimension that is narrower in width then in a length, wherein the length extends from the lower end to the upper end of the annular body;
wherein a pair of adjacent elongated bosses define a gap that extends from a lower end to an upper end of the annular body; the gap having a varying width dimension with a narrower upper end than a wider lower end.
15. The cassette recited in claim 14 , wherein the gap is smaller in width than in a length, and wherein the length extends from the lower end to the upper end of the annular body.
16. The cassette recited in claim 14 , wherein the annular cover has at least one radial gap which is adapted to receive an indexing mechanism for rotation or prevention of a rotation.
