Cassette and apparatus for packing disposable objects into an elongated tube of flexible material

Abstract

A cassette for dispensing bags from an elongated tubing comprising an annular receptacle accommodating a length of tubing in an accumulated condition. An annular opening at an upper end of the annular receptacle is for dispensing the tubing. The annular receptacle defines a central opening through which a knotted end of the tubing passes to form a bag supported by the annular receptacle with disposable objects passing through the circular central opening to be received in the bag, and a clearance only at a bottom of the central opening.

1 . A cassette for packing at least one disposable object, comprising:
 an annular receptacle including an inner annular wall delimiting a central opening of the annular receptacle, an outer annular wall, a bottom horizontal wall at a bottom end of the cassette, and a volume receiving an elongated tube of flexible material radially outward of the inner annular wall and radially inward of the outer annular wall, the annular receptacle including a clearance defined by a portion of the inner annular wall extending obliquely upward from a junction with the bottom horizontal wall, said portion of the inner annular wall joining with an upright portion of the inner annular wall whereby the clearance opens into the central opening;   a length of the elongated tube of flexible material disposed in an accumulated condition in the volume of the annular receptacle; and   an annular opening at an upper end of the annular receptacle for dispensing the tubing such that the elongated tube extends through the central opening of the annular receptacle to receive disposable objects in an end of the elongated tube,   wherein at least a portion of the volume of the annular receptacle is located radially outward of and side by side with at least a portion of the clearance such that at least a portion of the elongated tube of flexible material is disposed in the accumulated condition in said portion of the annular receptacle.   
     
     
         2 . The cassette according to  claim 1 , wherein the clearance in the cassette has the shape of a chamfer. 
     
     
         3 . The cassette according to  claim 1 , wherein the clearance extends on the full periphery of the central opening. 
     
     
         4 . The cassette according to  claim 1 , wherein the outer annular wall projects generally upwardly from the bottom horizontal wall. 
     
     
         5 . The cassette according to  claim 1 , wherein the inner annular wall, the clearance, and the bottom horizontal wall and the outer annular wall extend continuously. 
     
     
         6 . The cassette according to  claim 1 , wherein the clearance is entirely located in a bottom half of the inner annular wall. 
     
     
         7 . The cassette according to  claim 1 , further comprising a lid connected to at least one of the inner annular wall and the outer annular wall to partially cover the annular opening. 
     
     
         8 . The cassette according to  claim 7 , wherein the lid is connected to the inner annular wall and projects radially outward therefrom.
