Description

  The present invention relates to a waste disposal apparatus for disposing of waste such as used infant diapers.

  As a technology of a filth disposal apparatus for disposing filth that emits an unpleasant odor such as a used infant diaper and which can continuously dispose of filth with excellent odor blocking properties, Japanese Patent Laid-Open No. 1-222601 Japanese Laid-Open Patent Publication No. 2009-96642 (Patent Document 2) and Japanese Laid-Open Patent Publication No. 7-330103 (Patent Document 3) are disclosed.

  The waste disposal apparatus described in Patent Document 1 and Patent Document 2 is shown in FIG. In the waste disposal apparatus described in Patent Literature 1 and Patent Literature 2, a cylindrical film 101 whose one end is closed, a tubular guide 102 for inserting and accommodating the film, and the film 101 and the tubular guide 102 are manually twisted. Twisting means 103.

  This waste disposal apparatus draws out the closed end of the film 101 inserted through the tubular guide 102 and pushes it toward the coaxial lower side of the tubular guide 102 to form a waste storage space. After discarding the waste in the waste storage space, the tubular guide 102 is rotated by the twisting means 103 to provide a closing portion 104 by twisting on the film between the waste and the tubular guide 102.

  The torsion closing portion of the film forms the bottom of the waste storage space for the next waste disposal, and blocks the transmission of odors leaking from the waste to the outside. With such a structure, filth can be continuously discarded in the film, and the odor of the filth can be effectively blocked.

  Moreover, the waste disposal apparatus described in Patent Document 3 is shown in FIG. The waste disposal apparatus described in Patent Document 3 includes a waste storage body 105 having an opening upward, a lid 106 that closes the opening, and a flexible film 107 that houses the waste 110 disposed in the waste storage body. And a closing mechanism 108 for sandwiching the film 107 between the waste storage body 105 and the opening.

  The closing mechanism 108 has a pair of rod-like sandwiching members 109. When discarding filth, the closing mechanism 108 is opened to discard the filth in the filth storage body 105. After disposal, the rod-like sandwiching member 109 removes the film 107. The filth 110 that is sandwiched and discarded is blocked from the outside world. This closing mechanism 108 blocks the transmission of odors leaking from dirt to the outside.

Japanese Patent Laid-Open No. 1-2226601 JP 2009-96642 A JP 7-330103 A

  However, the waste disposal apparatuses described in Patent Literature 1 and Patent Literature 2 are insufficient in terms of blocking the odor of the waste. That is, in the waste disposal apparatus described in Patent Document 1 and Patent Document 2, a large element that blocks the odor of the waste is the closing portion 104 by twisting of the film 101, and a linear micro-ventilation is always placed on the central axis of the twist. The route remains. Such a residual ventilation path causes odor leakage.

  Further, the twist of the film gradually loosens with time due to the restoring force of the film against the twist. This has led to the expansion of the residual ventilation path, and has become a factor that further reduces the odor blocking ability. Furthermore, since the closed portion 104 of the film twist is generated every time the waste is disposed of, the maximum amount of waste that can be stored in the waste disposal apparatus is reduced.

  The waste disposal apparatus described in Patent Document 3 is also inadequate in terms of blocking off the odor of waste. That is, in the waste disposal apparatus described in Patent Document 3, the means for blocking the odor of the waste is sandwiching the film 107 by the pair of rod-like members 109 of the closing mechanism 108. Therefore, the contact shape between the rod-shaped member 109 and the film 107 formed by the film 107 being sandwiched between the pair of rod-shaped members 109 forms a line instead of a surface. This is a factor that makes the odor blocking property between the filth 110 housed below the closing mechanism 108 and the opening above the closing mechanism 108 insufficient.

  This invention solves the said subject, and it aims at providing the filth processing apparatus for discarding filth, such as a used infant diaper excellent in the odor blocking | blocking property.

  The waste disposal apparatus of the present invention has a tubular core portion that forms a waste inlet at the upper end, a film storage portion that stores a film compressed in a cylindrical shape so as to surround the tubular core portion, and a film storage portion at the top And a filth storage body for receiving the filth introduced into the film fed into the filth input port together with the film. In addition, an opening / closing type sealing mechanism is provided that sandwiches the film between the film storage unit and the filth storage main body and blocks the upper and lower spaces. Furthermore, the sealing mechanism has a sealing door that can be opened and closed, and a sealing door receiving portion that sandwiches the film together with the sealing door in the closed position, and the film sandwiching portion of the sealing door and the sealing door receiving portion is sandwiched. Including an uneven shape that bends the intermediate portion in the vertical direction of the film portion laterally with respect to a virtual straight line connecting the upper end and the lower end of the sandwiched film portion.

  According to the present invention, the filth introduced into the film and the filth input port are blocked by the film being sandwiched between the sealing door and the sealing door receiving portion. Furthermore, since the film is sandwiched by the concavo-convex shape provided in the sealing door and the sealing door receiving portion, the film is bent sideways with respect to the virtual straight line instead of being linear. Therefore, a large tension is applied to the film at the bent portion. By this tension, the residual ventilation path is narrowed, and it is possible to improve the blocking of odor transmission. Moreover, since there is no need to twist the film every time the waste is discarded, it is possible to prevent the maximum amount of waste stored by the twisted portion from decreasing.

  As a preferred embodiment, the concave and convex shapes of the sealing door and the sealing door receiving portion that are closed and engaged with each other are each composed of a plurality of surfaces.

  According to this embodiment, the number of points where the film is tensioned increases as the number of bent portions of the film sandwiching portion increases. This further improves the odor blocking property. The uneven shape may be configured by a back surface or a curved surface.

  As a preferred embodiment, at least two of the plurality of surfaces constituting the concavo-convex shape are connected at substantially right angles to form corners.

  According to this embodiment, at least one location where the film is bent at a substantially right angle by being sandwiched between the sealing door and the sealing door receiving portion is formed. A large tension is applied to the film at the substantially right-angled bent portion, and the residual ventilation path can be narrowed to further improve the odor blocking property. In addition, when the sealing door and the sealing door receiving portion are mass-produced by mold molding, the L-shape bent at a substantially right angle is not a particularly complicated shape, so that molding is easy. Therefore, it has an advantage regarding mass production of the product.

  As a preferred embodiment, the sealing door has a film sandwiching portion formed at the front end portion of the sealing door, and is pivotally supported by the waste storage body or the sealing door receiving portion at the rear end portion.

  According to this embodiment, the opening / closing operation of the sealing door is realized by the rotation of the sealing door. Therefore, when the user pushes filth into the filth storage main body, the sealing door can be opened more easily.

  As a preferred embodiment, the sealing mechanism may further include an elastic member that biases the sealing door toward the closing direction.

  According to such an embodiment, it is possible to increase the force for sandwiching the film, and the odor blocking property can be further improved.

  As a preferred embodiment, the elastic member is a single elastic material that can be expanded and contracted in the extending direction, both ends of the elastic member are connected to the left and right side edges of the sealing door receiving portion, respectively, and the central region of the elastic member is It is stretched over the lower surface of the sealing door.

  According to this embodiment, the elastic member for urging the sealing door in the closing direction can be realized with only one elastic material. Furthermore, since the elastic material is applied to the lower surface of the sealing door by one elastic material and biased in the closing direction, the sealing door can be biased with a substantially equal force on the left and right.

  As a preferred embodiment, the sealing door includes an elastic member guide that holds the central region of the elastic member on the lower surface of the sealing door.

  According to this embodiment, the elastic member stretched over the lower surface of the sealing door is stably fixed at a predetermined position on the lower surface of the sealing door by the elastic member guide. Therefore, the sealing door is stably urged toward the closing direction by the elastic member.

  As a preferred embodiment, the sealing mechanism has a left-side elastic member cover in which the upper end side is locked to the left side edge of the sealing door receiving portion and the lower end side is locked to the left side edge of the sealing door to accommodate the left end portion of the elastic member. And a right side elastic member cover that locks the upper end side to the right side edge of the sealing door while the lower side locks to the right side edge of the sealing door. These elastic member covers follow the opening and closing of the sealing door while being locked to the left and right side edges of the sealing door.

  According to this embodiment, the elastic member located on both side edges of the sealing door and the sealing door receiving portion is always covered by the elastic member cover regardless of the opening / closing operation of the sealing door. Therefore, it can prevent that the film which accommodates filth is caught in an elastic member, and is torn. In addition, these elastic member covers can protect both side portions of the elastic member. Accordingly, even when the elastic member guide is not provided on the sealing door, the elastic member can be prevented from falling off the sealing door.

  As a preferred embodiment, the film storage portion is supported by the filth storage body so that the axis of the tubular core portion is inclined at a predetermined angle.

  According to this embodiment, after the mother changes the diaper while sitting, it becomes easy to discard the filth to the filth input port while sitting down.

  As a preferred embodiment, the lower end portion of the film storage portion that surrounds the lower end of the tubular core portion is supported at a predetermined angle and is supported at a low position in the vertical direction on the front end side and a high position in the vertical direction on the rear end side. The concavo-convex shape of the sealing door receiving portion is arranged in the vicinity of the lowest position of the lower end portion of the film storage portion.

According to this embodiment, the film stored in the film storage portion so as to be able to be fed out from the filth input port passes through the inside of the tubular core portion that is inclined and supported vertically, and stores the filth together with the filth. It is stored inside the main body. Here, the film is pulled down vertically because of the weight of waste disposed inside the film. When the diameter of the waste inlet and the inclination angle theta _O from the horizontal direction is L _O, the film only L _{O (1-cosθ O)} as at least a distance, by the inclination of the gravity and tubular core, is inclined tubular It will be naturally brought toward the lowest position side of the lower end part of the core part. Further, the above-described sealing mechanism is arranged so that the film is sandwiched in the vicinity of the lowest position in the lower end portion of the tubular core portion naturally brought together in this way. This makes it easier to sandwich the film by the sealing mechanism and can be expected to increase the efficiency of blocking.

  As a preferred embodiment, the sealing door is tilted and supported at a predetermined angle at the closed position, and is set at a low position in the vertical direction on the front end side and at a high position in the vertical direction on the rear end side.

  According to this embodiment, since the mother can change the diaper while sitting, it is easy to push open the sealing door while sitting down, and thus the work of disposing of the filth into the filth input port is facilitated.

  As a preferred embodiment, the film sandwiching portion of the sealing door and the sealing door receiving portion is formed on the front side of the filth storage body. In addition, the filth storage body has an inclined surface whose vertical height decreases from the front side to the rear side in the front region of the inner bottom surface.

  According to this embodiment, the filth discarded inside the filth storage body slides down toward the rear side of the filth storage body due to the slope provided at the bottom, so that the filth is efficiently accumulated inside. .

  As a preferred embodiment, the film storage portion is a film storage cassette, and includes a tubular core portion, a tubular core flange extending from the lower end portion of the tubular core portion in an outer diameter direction, and an outer end portion from the upper end portion of the tubular core portion. A film holding flange that extends in the radial direction and accommodates the film in a compressed state between it and the tubular core flange, and allows the film to pass over the outer edge and feed out to the tubular core. And it attaches to the upper part of a filth storage body so that attachment or detachment is possible.

  According to this embodiment, when all of the consumable films are used, the user can replace and set the film storage cassette by a simple operation.

  According to the waste disposal apparatus of the present invention, the shielding between the waste introduced into the film and the waste inlet is realized by sandwiching the film by the sealing door and the sealing door receiving portion. Furthermore, since the film is sandwiched by the concavo-convex shape provided in the sealing door and the sealing door receiving portion, the film is bent sideways with respect to the virtual straight line instead of being linear. Therefore, a large tension is applied to the film at the bent portion. By this tension, the residual ventilation path is narrowed, and it is possible to improve the blocking of odor transmission.

FIG. 2 shows a closed state of the sealing door, and FIG. 3 shows an opened state of the sealing door.

  The filth processing apparatus 11 includes an annular filth input port 16 into which filth D such as a used diaper is input, a cylindrical film 15 extending downward from the filth input port 16 and closed at the lower end by a knot 26, A filth storage body 13 that receives the filth D introduced from the mouth 16 together with the film 15 and a lid 23 that covers the filth input 16 from above.

  A long film 15 is attached to the filth input port 16. The film 15 extends downward so as to cover the mouth of the filth input port 16.

  The filth storage main body 13 is a hollow container for storing the filth D discarded inside the film 15, and is divided into a storage main body lower portion 17 and a storage main body upper portion 19. The storage main body lower portion 17 has a bottom portion 17b on the lower end side and an opening on the upper end side. The storage main body upper portion 19 covers the opening at the upper end of the storage main body lower portion 17 on the lower end side, and has a filth input port 16 at the upper end portion.

  In addition, an opening / closing type sealing mechanism 28 that sandwiches and blocks the film 15 between the filth input port 16 and the stored filth is provided inside the storage main body upper portion 19. The sealing mechanism 28 includes a sealing door 33 and a sealing door receiving portion 35. The sealing mechanism 28 will be described later.

  When disposing of the filth, the user first opens the lid 23 and then inserts the filth D into the film 15 from the filth input port 16. Next, the user puts his hand into the filth input port 16 and pushes down the film 15 together with the filth D to push open the sealing door 33. The filth D pushed downward passes between the sealing door 33 opened with the film 15 and the sealing door receiving portion 35. The filth D that has passed through the sealing door 33 and the sealing door receiving portion 35 travels downward through the film 15 and is accumulated inside the filth storage body 13. When the user drops filth below the sealing door 33 and the sealing door receiving portion 35 and removes the hand from the trash input 16, the sealing door 33 immediately closes and the film 15 is sandwiched. Further, since the new film 15 is fed out from the filth input port 16, the new film 15 is always supplied to the filth input port 16.

  4 is an enlarged cross-sectional view of the sealing mechanism 28 shown in FIG. 2 in an enlarged cross-sectional shape when the door is closed, and FIG. 5 is an enlarged view of the cross-sectional shape of the sealing mechanism 28 shown in FIG. FIG. In addition, the line O in FIG. 4 shows the central axis line of the filth inlet 16 and the tubular core part mentioned later.

  As described above, the waste disposal apparatus 11 includes the opening / closing type sealing mechanism 28 that sandwiches and blocks the film 15 between the waste inlet 16 and the waste D discarded in the waste storage body 13. The sealing mechanism 28 includes a sealing door 33 and a sealing door receiving portion 35. The sealing door 33 and the sealing door receiving portion 35 are engaged with each other when the sealing door 33 is closed. An uneven shape for sandwiching the film is provided. This configuration will be described later.

  In a state where the sealing door 33 and the sealing door receiving portion 35 are closed, the sealing door receiving portion 35 is attached to the upper portion 19 of the storage main body 19 so that the sealing door 33 covers and closes the waste inlet 16 from below. It is provided inside. A guide rail 37 that guides the sealing door 33 to operate in the opening direction and the closing direction is attached to the inner wall of the upper portion 19 of the storage body. The guide rail 37 is disposed so as to extend downward from the sealing door receiving portion 35, and the sealing door 33 slides along the guide rail 37.

  The sealing door 33 is biased toward the sealing door receiving portion 35 and is normally engaged with each other and closed. In a normal state, as shown in FIG. 2, the film 15 is sandwiched between the sealing door 33 and the sealing door receiving portion 35. On the other hand, when the user pushes down the sealing door 33, the sealing door 33 slides along the guide rail 37 in the opening direction away from the sealing door receiving portion 35. When the sealing door 33 is opened, as shown in FIG. 3, the pinching of the film 15 is released, and the filth D can be thrown into the filth storage body 13.

  In the present embodiment, as shown in FIGS. 2 to 5, the sealing door 33 and the sealing door receiving portion 35 are provided with a pair of concave and convex shapes that engage with each other when the door is closed. The film 15 is sandwiched between the concave and convex shapes provided in the sealing door 33 and the sealing door receiving portion 35. The concavo-convex shape provided on the sealing door 33 is constituted by a sandwiching surface 33c that comes into contact with the film 15 when the door is closed. Further, the uneven shape provided in the sealing door receiving portion 35 is constituted by a sandwiching surface 35c that comes into contact with the film 15 when the door is closed.

  Here, the sandwiching surfaces 33c and 35c will be described in detail with reference to FIG. FIG. 6A is an enlarged side cross-sectional view schematically showing a film sandwiching portion when the sealing door 33 and the sealing door receiving portion 35 according to the present embodiment are opened. FIG. 6B is an enlarged side cross-sectional view schematically showing an enlarged film sandwiching portion when the sealing door 33 and the sealing door receiving portion 35 according to the present embodiment are closed. In addition, since FIG. 6 typically shows the film sandwiching portions of the sealing door 33 and the sealing door receiving portion 35 for easy understanding, the detailed configuration is different from the actual embodiment. .

As shown in FIG. 6A and FIG. 6B, a sandwiching surface 33c corresponding to the film sandwiching portion of the sealing door 33 includes a surface 33c ₁ corresponding to the front end region of the top surface of the sealing door 33, and a surface It extends downward in front of 33c ₁ connected substantially at a right angle to the surface 33c _1, and the surface 33c ₂ which forms a corner of the surface 33c ₁ substantially at right angles, substantially at a right angle to the surface 33c ₂ in the lower end surface 33c ₂ It extends to the front side to connect, and from the surface 33c ₃ Metropolitan forming the corner portion of the surface 33c ₂ substantially perpendicular.

Furthermore, nipping surface 35c, which corresponds to the film nipping portions of the sealing door receiving portion 35 is provided so as the upper end of the film nipping portions to the axis O substantially perpendicular to the waste inlet 16, the surface 33c ₁ substantially parallel when the door is closed the surface 35c ₁ of the extending downwardly connected substantially at a right angle to the surface 35c ₁ at the front end surface 35c _1, and the surface 35c ₂ which is substantially parallel to the surface 33c ₂ when the door is closed, faces the bottom end surface 35c ₂ It extends to the front side connected substantially at a right angle and 35c _2, consists of the surface from 35c ₃ Metropolitan substantially parallel to the plane 33c ₃ when closing.

The sealing door 33 slides in the direction of the arrow in FIG. 6 (a) from the opened state shown in FIG. 6 (a) to sandwich the film 15, and the closed state shown in FIG. 6 (b). As a result, the film 15 is bent at substantially right angles at the two corners α ₁ and α ₂ . That is, the intermediate points α ₁ and α ₂ in the vertical direction at the sandwiched portion of the film 15 sandwiched by the sealing door 33 and the sealing door receiving portion 35 are shown by the alternate long and short dash lines in FIG. Is bent sideways with respect to a virtual straight line connecting the upper end β and the lower end γ of the sandwiched portion. Further, the corner portions formed on the rear end surface 35c _1, the film 15 is bent also at the upper end β of the film nipping portions. Similarly, the corner portion formed at the front end surface 33c _3, the film 15 is bent also at the lower end γ of the film nipping portions.

Here, the filth D discarded inside the film 15 is subjected to gravity downward due to its own weight. In other words, the film 15 is always subjected to a vertically downward tension by the dirt D. When the film 15 in such a state where tension is applied is sandwiched as shown in FIG. 6B and the film 15 is bent at four corners of α ₁ , α ₂ , β, and γ, Greater tension is applied to the film 15. Thereby, the residual ventilation path which becomes a factor for transmitting the odor in the above-described prior art is effectively blocked. Therefore, the odor blocking ability can be greatly improved. Moreover, since there is no need to twist the film every time the waste is discarded, it is possible to prevent the maximum amount of waste stored by the twisted portion from decreasing. Further, when the sealing door 33 and the sealing door receiving portion 35 are mass-produced by molding, the uneven shape having a substantially right-angled corner is a step-like shape and not a particularly complicated shape. Therefore, molding is easy. Therefore, it has an advantage regarding mass production of the product.

  Another embodiment of the sealing door 33 and the sealing door receiving portion 35 is schematically shown in FIGS. FIG. 7A is an enlarged side cross-sectional view showing a film sandwiching portion at the time of opening the convex-shaped sealing door and the concave-shaped sealing door receiving portion according to another embodiment. FIG. 7B is an enlarged side cross-sectional view showing a film sandwiching portion when the convex-shaped sealing door and the concave-shaped sealing door receiving portion of the embodiment are closed. In addition, since FIG. 7 typically shows the film sandwiching portions of the sealing door 33 and the sealing door receiving portion 35 for easy understanding, the detailed configuration is different from the actual embodiment. .

  In this embodiment, the sandwiching of the form 15 by the sealing door 33 and the sealing door receiving portion 35 includes a sealing door 33 provided with a film sandwiching portion having a convex side cross section, and the sealing door. This is realized by engagement with a hermetic door receiving portion 35 provided with a film sandwiching portion having a concave-shaped side cross section for receiving the convex shape provided in 33.

  Specifically, a protrusion 133 having a convex cross section is formed on the sandwiching surface 33c. A groove 135 having a concave cross section is formed on the sandwiching surface 35c. The protrusion 133 protrudes so as to be substantially parallel to the sliding direction of the sealing door 33. Therefore, when the sealing door 33 slides in the closing direction and engages with the sealing door receiving portion 35, the sealing door 33 and the sealing door receiving portion 35 are provided without hindering the sliding. The uneven shape is engaged.

As shown in FIG. 7, the surfaces constituting the sandwiching surface 33 c formed on the sealing door 33 are 33 c _{1 to} 33 c ₅ , respectively. The surface constituting the nipping surface 35c that is formed in the sealing door receiving portion 35 is _35c 1 _{~35c 5} respectively. Among these constituent surfaces, 33c ₂ and 33c ₄ and 35c ₂ and 35c ₄ are surfaces substantially orthogonal to a virtual straight line connecting the upper end β and the lower end γ of the film sandwiching portion shown in FIG. 7B. Therefore, the sealing door 33 slides in the direction of the arrow in FIG. 7A from the opened state shown in FIG. 7A to sandwich the film 15 and the closed state shown in FIG. 7B. Then, the film 15 is bent at substantially right angles at the four corners α _{1 to} α ₄ . That is, the film 15 is bent in a substantially horizontal direction between α _{1 to} α _{2 and} between α _{3 to} α ₄ .

  Similarly to FIG. 6 described above, gravity downwardly acts on the film 15 by the dead weight of the filth D. Therefore, a large tension is applied to the film 15 at the corners at approximately four right angles. Thereby, the residual ventilation path formed along the inner side of the film 15 is bent at a right angle, and the odor can be blocked more effectively. Moreover, since there is no need to twist the film 15 every time waste is discarded, it is possible to prevent the maximum amount of waste stored by the twisted portion from decreasing. Further, when the sealing door 33 and the sealing door receiving portion 35 are mass-produced by mold molding, the uneven shape is easy to mold, and thus has an advantage in mass production of products.

  Further, the waste disposal apparatus 11 further includes a spring 39 for constantly urging the sealing door 33 toward the sealing door receiving portion 35. As the urging force of the spring 39 is larger, it is possible to increase the force for sandwiching the film 15 and to further improve the odor blocking property.

  FIG. 8 is an exploded perspective view showing the film storage unit 14 taken out. The waste disposal apparatus 11 includes a film storage portion 14 that forms the waste inlet 16 and stores the film 15. The film storage portion 14 is detachably attached to the film attachment portion 12 provided above the storage main body upper portion 19, and forms an outline of the filth input port 16. The film storage portion 14 is fitted into the cylindrical tubular core portion 27 extending downward from the waste inlet 16, the tubular core flange 27 f provided at the lower end portion of the tubular core portion 27, and the upper end side of the tubular core portion 27. And a flange-shaped film holding flange 29 to be fixed.

  The film 15 is inserted so that it is folded in a bellows shape in the axial direction of the tubular core portion 27 and is coaxially disposed on the outer diameter side of the tubular core portion 27. The film holding flange 29 is fitted and connected to the tubular core portion 27 so as to prevent the film 15 from popping out. In other words, the film 15 is formed in the direction of the axis O of the tubular core portion 27 by the film holding flange 29 positioned at the upper end of the tubular core portion 27 and the tubular core flange 27 f positioned at the lower end of the tubular core portion 27. The space between the upper end and the lower end in the direction of the axis O is folded and compressed in a bellows shape and stored.

  The film 15 is a consumable part of the film storage unit 14. When all the stored film is used, the user removes the used film storage unit 14 and replaces the new film storage unit 14 with the film attachment unit 12. set. Alternatively, the film storage unit 14 may be configured such that only the film is replaced when all the films 15 stored in the film storage unit 14 are used. That is, the tubular core flange 27 f may be fixed to the film attachment portion 12, and the film holding flange 29 may be detachably attached to the tubular core portion 27. According to this configuration, when replacing the film, the user can remove the film holding flange 29 and replace only the film.

  After the film storage unit 14 is set in the waste disposal apparatus 11, the user passes the distal end of the film 15 compressed and stored in the tubular core portion 27 with the lid 23 open, beyond the outer peripheral edge of the film holding flange 29. Pull out upward. The drawn tip is then closed by the knot 26. Then, the knot 26 is inserted into the tubular core portion 27 and pushed downward, and the knot 26 is pushed to the bottom portion 17b while the film 15 is fed out from the film storage portion 14. When filth such as used diapers is discarded inside the film 15, the filth is accumulated in the film 15, and the film 15 folded in a bellows shape on the outer diameter side of the tubular core portion 27 is drawn out one after another. And grow downward. Therefore, the user can continuously dispose of the filth in the filth storage body 13.

As shown in FIG. 4, in the waste disposal apparatus 11 of the present embodiment, the film storage portion 14 is arranged such that the direction of the axis O of the tubular core portion 27, that is, the opening direction of the waste inlet 16 is inclined at a predetermined angle. Is supported by the storage main body upper portion 19. The filth input port 16 is inclined at a predetermined angle θ ₁₆ from the vertical direction toward the front side. Thereby, the operation | work which a mother discards a baby's diaper can be made easy. This will be briefly described below. In many cases, the mother exchanges the infant's diaper with the infant lying on the floor and the mother sitting. Therefore, according to the present embodiment, since the filth input port 16 is inclined at the predetermined angle θ ₁₆ , the mother sits down and replaces the infant's diaper, and the used diaper (dirt) is left in the sitting state. The operation of disposing of the waste into the filth input port 16 becomes easy.

  Although not shown in the drawing, the film storage portion 14 may be supported by the storage main body upper portion 19 so that the opening direction of the filth input port 16 is horizontal. In this case, the axis O of the tubular core portion 27 extends horizontally. This is because even in such a case, tension can be applied to the sandwiched film portion.

  As shown in FIGS. 4 and 5, the sealing door 33 has a substantially flat sealing door upper surface 34. The detailed shape of the sealing door upper surface 34 will be described later. In the waste disposal apparatus 11 of the present embodiment, the sealing door 33 is supported on the storage main body upper portion 19 so that the sealing door upper surface 34 is inclined at a predetermined angle corresponding to the inclined axial direction of the tubular core portion 27. Has been. That is, the sealing door 33 is supported by the storage main body upper portion 19 at a predetermined angle so that the front end side is a low position in the vertical direction and the rear end side is a high position in the vertical direction when the door is closed. . The sealing door 33 moves forward and backward at a predetermined angle toward the sealing door receiving portion 35. The forward / backward moving direction S of the sealing door 33 is inclined at an angle different from the axis O of the tubular core portion 27.

Specifically, as shown in FIG. 4, the inclination angle of the waste inlet 16 (the tubular core 27) and theta ₁₆ relative to the vertical direction, the inclination angle of the forward and backward direction S of the sealing door 33 with respect to the vertical direction theta _{As 33} , the following expression (1) is satisfied.

0 ° <θ ₁₆ <θ ₃₃ (1)
According to this embodiment, the inclination angle θ _{33 of} the sealing door 33 in the advance / retreat direction S is larger than the inclination angle θ ₁₆ of the filth input port 16. As a result, as the sealing door 33 is retracted in the opening direction, the sealing door 33 is translated downward and rearward and away from the axis O of the tubular core portion 27. That is, the sealing door 33 can be sufficiently separated from the film 15 when the door is opened. Therefore, since the film 15 is largely opened when the door is opened, the user can easily dispose of the filth toward the filth storage body 13 while sitting.

Incidentally, although not shown in the figure, as the sealing door top 34 are vertical, the sealing door 33 may be supported in the housing body upper _{19 (θ 33 = 90 °)} . In this case, the sealing door 33 moves forward and backward in the horizontal direction. In such a case, the sealing door 33 can be effectively separated from the film 15 when the door is opened.

  In addition, according to the present embodiment, the tubular core flange 27f corresponding to the lower end portion of the film storage portion 14 disposed so as to surround the lower end of the tubular core portion 27 is disposed so that the filth storage body is inclined at a predetermined angle. 13 is supported. That is, as shown in FIGS. 2 to 5, the front end side of the tubular core flange 27 f is a low position in the vertical direction, and the rear end side is a high position in the vertical direction. The sandwiching surface 35c of the sealing door receiving portion 35 is disposed in the vicinity of the lowest position of the tubular core flange 27f. Thereby, the film 15 is more easily sandwiched by the sealing door 33. This will be described below.

The film 15 stored in the film storage portion 14 so as to be able to be fed out from the filth input port 16 passes through the inside of the tubular core portion 27 vertically downward, and is stored in the storage body lower portion 17 together with the filth D. Therefore, when the sealing door 33 is opened, the film 15 is pulled vertically downward by the weight of the waste D discarded inside the film 15, so that the film 15 is almost straight downward from the waste input port 16. Extend. Here, the tubular core 27, as described above, is inclined at a predetermined angle theta _16. Accordingly, the diameter of the waste inlet 16 and L _O, when the inclination angle with respect to the horizontal direction of the waste inlet 16 and θ _{O (=} θ _16), the film 15 extends straight downward from the waste inlet 16 If only _{L O (1-cosθ} O) as at least a horizontal distance, so that the asked forward inclined downward with nature. In this manner, the film 15 is sandwiched between the sealing door 33 and the sealing door receiving portion 35 on the inclined lower side which is naturally brought closer. Thereby, since the film 15 can be more easily sandwiched by the sealing door 33, it is possible to more efficiently perform sealing for blocking odors.

  In the present embodiment, as described above, the sealing door upper surface 34 is formed to be substantially flat, but strictly speaking, the sealing door upper surface 34 is an upper surface that is a substantially flat surface.

This will be described with reference to FIG. As described above, the film storage portion 14 is supported by the storage main body upper portion 19 so as to be inclined downward on the front side. Further, the sealing door 33 engages with the sealing door receiving portion 35 on the front side, that is, the inclined lower side, and sandwiches the film. Here, when the sealing door 33 is closed, the sandwiching surface 35c of the sealing door receiving portion 35 is interposed between the film storage portion 14 and the upper surface front portion 34f. On the other hand, the sandwiching surface 35c of the sealing door receiving portion 35 is not interposed between the film storage portion 14 and the upper surface rear portion 34r. From this, the sealing door upper surface 34 comes into contact with the sealing door receiving portion 35 to close the filth input port from below, so that two different surfaces (a flat surface upper surface front portion 34f and an inclined surface upper surface rearward). Part 34r).

Here, in the present embodiment, as shown in FIG. 4, the angle between the upper surface front portion 34f and the horizontal surface is θ _34f, and the angle between the upper surface rear portion 34r and the horizontal surface is θ _34r. The sealing door upper surface 34 is formed so as to satisfy the above.

0 ° ≦ θ _34f <θ _34r (2)
