More specifically, each of the sealing door 33 and the sealing door receiving portion 35 has a convexo-concave shape that laterally bends an imaginary straight line that connects upper and lower ends of the nipped portion of the tubular film 15.
  • sealing the waste material D placed and stored in the tubular film 15 from the waste inlet 16 is implemented by nipping of the tubular film 15 by the sealing door 33 and the sealing door receiving portion 35. Moreover, since the nipped portion of the tubular film 15 is not bent linearly but laterally with respect to the imaginary straight line. Thus, the tubular film 15 is subjected to a high tension at a bent portion. Such a tension narrows a path in the tubular film 15 which causes leakage of odors, whereby a capability of blocking passing of odors, namely an odor-sealing capability, can be increased.
  • each of the contact surfaces of the sealing door 33 and the sealing door receiving portion 35 which are formed when the sealing door 33 is closed and engages with the sealing door receiving portion 35, has two or more flat surfaces having different normals.

  • the tubular film 15 is pulled downward at the L-shaped corner by the weight of the waste material D. That is, the tubular film 15 is subjected to a tension at the L-shaped corner. This narrows a path in the tubular film 15, whereby the odor-sealing capability can further be increased.
  • Such L shapes can be easily formed when mass producing the sealing door 33 and the sealing door receiving portion 35 by a die molding method.
  • the present invention is advantageous in terms of mass production of products.
  • the waste disposal apparatus 11 further includes the spring 39 for biasing the sealing door 33 in the closing direction. This increases the force for nipping the tubular film 15, whereby the odor sealing capability can further be increased.
  • the spring 39 may be in other form as long as it is an elastic member.
  • the cylindrical portion 27 is supported by the waste accommodating main body 13 so that the axis of the cylindrical portion 27 crosses a vertical plane at a predetermined angle. This makes it easy for mothers to insert the waste material D through the waste inlet 16 without standing up after changing diapers while sitting on the floor.
  • the cylindrical portion 27 is supported in a tilted state by the waste accommodating main body 13 so that the axis of the cylindrical portion 27 crosses the vertical plane at the predetermined angle and the front side of the cylindrical portion 27 is located lower than the rear side thereof.

  • the zipper 54 at one end is provided to open a waste inlet by lifting the lid 52.
  • a handle 56 is sewn on the surface of the lid 52 so that the user can conveniently carry the waste disposal bag 51.
  • a fixing belt 58 is wound around the one end of the waste disposal bag 51.
  • Two fastening members 60 which are rectangular rings, are attached to the circumferential fixing belt 58 at intervals in the circumferential direction.
  • an outer ring 24 is placed on the outer periphery of the film annular body 15k so that one axial end 25 of the outer ring 24 is fitted on the outer edge of the outward flange 27f.
  • the outer ring 24 is a cylindrical body having openings at both ends, and has an inner diameter dimension large enough to surround the outer periphery of the film annular body 15k.
  • the outer ring 24 is formed by a durable, strong resin.
  • Circumferential ribs 28 are formed in two parallel rows in the outer peripheral surface of the outer ring 24. The distance between the two rows of the ribs 28 is the same as the width dimension of the fixing belt 58.
  • the zipper 54 is opened, and the lid 52 is lifted open.
  • the accommodating cassette 14, which has a refill film placed thereon and is fitted in the outer ring 24, is inserted together with the tubular film 15 and the knot 26, which have passed through the central hole (the waste inlet 16), in the direction shown by arrow, and is thus attached to the waste disposal bag 51.
  • the fixing belt 58 is fastened to firmly attach the film annular body 15k and the accommodating cassette 14 to one end of the waste disposal bag 51.
  • the fixing belt 58 is latched between the two parallel rows of the ribs 28, 28 via the fabric of the waste disposal bag 51, and is wound around the outer periphery of the outer ring 24.
  • the waste disposal bag 51 surrounds the outer peripheries of the film annular body 15k and the accommodating cassette 14, and the outer wall of the tubular film 15 that is pulled out from the accommodating cassette 14 and passes through the central hole of the accommodating cassette 14 (the waste inlet 16).
  • the outer ring 24 may be omitted, and the outward flange 27f may be detachably and directly attached and fixed to the inner wall of the waste accommodating bag 51.
  • the outer ring 24 may be omitted, and only one end 21b ( Fig. 7 ) of the wrapping sheet 21 may be removed and the cylindrical portion 21a of the wrapping sheet 21 may be left when tearing off the wrapping sheet 21. Then, the fixing belt 58 may be wound around the outer wall of the cylindrical portion 21a of the wrapping sheet 21 so that the film annular body 15k and the accommodating cassette 14 are attached to the waste disposal bag 51.
  • waste materials such as soiled diapers can be placed and stored in the tubular film 15.
  • the waste disposal bag 51 of the present embodiment is preferable for portable applications, and enables the user to hygienically and efficiently dispose of waste materials such as soiled diapers.
  • the waste disposal bag 51 is long enough that the other longitudinal end of the waste disposal bag 51 can be twisted by 360° or more with respect to one longitudinal end thereof.
  • the user twists the waste disposal bag 51 by 360° or more as shown in Fig. 15 to prevent odors of stored waste materials D from leaking out of the waste disposal bag 51.
  • the user opens the zipper 54 to place a waste material D through the waste inlet 16, and finally closes the zipper 54. Disposal of the waste material D is completed in this manner.
  • the waste disposal bag of the present embodiment the user can successively dispose of waste materials D. Since the waste materials D are covered by the tubular film 15, and are sealed by the waste disposal bag 51, the waste disposal bag 51 is hygienic.
  • the user opens the zipper 55 at the other end of the waste disposal bag 51 as shown in Fig. 16 , and removes the waste materials D together with the tubular film 15 from the other end of the waste disposal bag 51. After removing all the waste materials D from the other end of the waste disposal bag 51, the user ties a knot, and cuts the bag of the tubular film 15 at the knot. The waste disposal bag 51 is thus emptied, and is ready for reuse. Note that at this time, a new length of the tubular film 15 is pulled out from the accommodating cassette 14, and thus the waste disposal bag 51 is always hygienic. The greater the overall length of the waste disposal bag 51 is, the more waste materials the waste disposal bag 51 can store.
  • fastening bands 62 are sewn on the lid 53.
  • the fastening bands 62 are radially arranged on the outer edge of the surface of the circular lid 53.
  • two fastening bands 62 are provided at intervals in the circumferential direction.
  • a pair of hook-and-loop fasteners 64 is sewn in the central part of each fastening band 62.
  • the fastening members 60 and the fastening bands 62 are fastening devices for restricting the length of the waste disposal bag 51.
  • the waste disposal bag 51 can be compressed to a compact size by first inserting the fastening bands 62 through the fastening members 60, namely the rectangular rings, and then folding back ends 62s of the fastening bands 62 and pressing the hook-and-loop fasteners 64 together.
  • the user can carry the waste disposal bag 61 in a preferred size.
  • the waste disposal bag 51 can be adjusted to any length by selecting the pressing positions of the hook-and-loop fasteners 64, which increases the convenience of carrying the waste disposal bag 51.
  • the user can loosen the fixing belt 58 to separate the accommodating cassette 14 from the waste disposal bag 51. Then, the user attaches the accommodating cassette 14 to the attachment portion 19r of the waste disposal apparatus 11. Note that when placing the refill film 18 on the accommodating cassette 14, the cylindrical portion 27 and the outward flange 27f of the accommodating cassette 14 may be kept attached to the attachment portion 19r. In this case, only the film holding flange 29 can be detached when placing the refill film 18 on the accommodating cassette 14. According to the present embodiment, since the refill film 18 can be directly placed in the waste disposal apparatus 11, the accommodating cassette 14 need not be thrown away when placing the refill film 18 on the accommodating cassette 14.
  • the film holding flange 29 can be omitted in the case where the film annular body 15k is maintained in the compressed state even after removing the wrapping sheet 21, and is stationarily placed in this state on the outer periphery of the cylindrical portion 27. If the tubular film 15 is neatly accordion folded to form the film annular body 15k, the tubular film 15 is sequentially pulled out from the accommodating cassette 14 and passes through the central hole of the cylindrical portion 27 to cover the waste inlet 16, even if the film holding flange 29 is not provided.
  • the refill film, the accommodating cassette, and the like according to the present invention are advantageously used in waste disposal apparatuses.
