  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 inlet 16 and the stored filth is provided in the upper portion 19 of the storage main body 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.

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 an enlarged 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 | gas_flowing path formed along the inner side of the film 15 is bent at right angle, and an odor can be interrupted | blocked more effectively. Moreover, since it is not necessary 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. Furthermore, 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. This is because 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)
Thus, when the user pushes open the sealing door 33 to discard the filth, the user can efficiently transmit the pressing force to the sealing door 33 by placing the hand on the upper rear portion 34r and pushing it. it can. Therefore, the user can open the sealing door 33 with less force.

  As a modification of the present embodiment, the upper surface rear portion 34r and the advance / retreat direction S may be substantially orthogonal. According to such a modification, the pressing force received by the sealing door 33 from the user's hand can be input to the spring 39 without any reduction. Therefore, the user can push open the sealing door 33 with less force.
