  • the chamfer clearance 41 is positioned downwardly.
  • a path of movement of the movable portion 58 is illustrated at B. It is observed that the movable portion 58 passes closely to the wall defining the chamfer clearance 41 . If the chamfer clearance 41 were not provided, the cassette 30 would impede the movement of the movable portion 58 . Accordingly, if the cassette 30 were installed upside down, the movable portion 58 would be prevented from moving along its path. Therefore, if a user person wants to use the cassette 30 properly, the cassette 30 must be oriented properly.
  • 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.
  • 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.
  • a mechanism includes additional parts.

  • a user person removes the lid 24 and funnel 25 assembly and inserts the cassette 30 in the correct orientation (i.e., with the chamfer clearance 41 facing downward.
  • the user person withdraws a free end of the tubing 32 from the cassette 30 , takes a leading edge of flexible tubing 32 , ties it into the knot 40 and pushes the knot 40 through the openings 22 , 34 and beyond the closing mechanism. It is pointed out that the knot 40 may be made prior to the cassette 30 being installed.
  • the movable portion 58 opens as a result of the downward pressure, whereby the knot 40 reaches the enclosure 18 below the closing mechanism 50 .
  • 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 .
  • 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.
  • 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 FIGS. 3B and 3C .
  • the angled receiving surface 62 of the movable portion 58 helps the downward force to be easily converted along the direction of the slots 66 such as to force the movable portion 58 from its closed position in contact with the fixed portion 52 ( FIG. 3A ) to its open position ( FIG. 3C ) against the force of the spring 67 , through a sliding movement illustrated by direction A in FIG. 1 .
  • the movable portion 58 Since the movable portion 58 is moved by the force applied on the disposable object, it slides only enough for the disposable object to go past the closing mechanism 50 , with most of the opening created by the movement of the movable portion 58 being blocked by the disposable object such as to minimize the propagation of odors through the opening 22 .
  • 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 FIGS. 1 and 3A , through a sliding movement, effectively sealing the object within the flexible tubing 32 .
  • the curved profile of the fixed portion 52 below the apex 60 and, more importantly, of the movable portion 58 below the apex 60 helps push the disposable object further down, if there is resistance, as the movable portion 58 returns to the closed position to apply a downward pushing force.
  • the cassette 30 ′ is provided with a tapered clearance 41 ′ (forming a frustoconical geometry at the outer periphery of the bottom of the cassette 30 ′) as opposed to a chamfer clearance 41 .
  • the tapered clearance 41 ′ is used in conjunction with a tapered flange 44 ′ in the holder 26 of the apparatus 10 , as is clearly illustrated in FIG. 4 (i.e., the flange 44 ′ defines an interference member of frustoconical shape). Accordingly, this complimentary shape ensures that the cassette 30 ′ is properly oriented in the holder 26 , otherwise the funnel 25 could not be installed properly on the top of the bin 12 . Moreover, the lid 24 and funnel 25 assembly would have problems closing with the improper orientation of the cassette 30 ′. It is pointed out that like reference numerals refer to like elements in FIGS. 1 and 4 .
  • 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 .
  • 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.
  • the fixed portion 52 ′ of the closing mechanism 50 has an upper end 54 ′ that extends upwardly in the opening 22 of the bin 12 .
  • the upper end 54 ′ is sized such that it also extends into the opening 34 of the cassette 30 when the cassette 30 is positioned in the holder 26 . If it were positioned upside down, the cassette 30 would extend above the annular flange 42 , and the ring 68 would not be positionable on the bin 12 .
  • the holder 26 features an interfering member 70 that has a shape that is complementary to that of the cassette 30 with the chamfer clearance 41 . With the presence of the interfering member 70 , the cassette 30 must properly be installed in the holder 26 to be used. As illustrated in FIG. 7 , a pair of interfering members 70 may optionally be provided on both side of the holder 26 .
  • 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 FIG. 1 .
  • the mechanism 50 greatly reduces the complexity of the apparatus 10 , makes the assembly simple, and allows for the use of a lesser quantity of flexible tubing 32 than prior-art devices.
  • angling the course of the movable portion 58 permits the optimization of little horizontal clearance versus the force required to bias the movable portion 58 .
  • the shape of the individual portions of the mechanism prevents disposable objects from “coming back up”—that is, once a disposable object has been inserted under pressure to pull film material, it will be forced to remain in the flexible tubing by the closing mechanism 50 .
