  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall perspective view showing a waste disposal apparatus according to an embodiment of the present invention. 2 and 3 are side sectional views showing the waste disposal apparatus according to the embodiment. 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 a 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, and the filth input port 16. A filth storage main body 13 that receives the filth D that has been input 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 waste inlet 16.

  The filth storage body 13 is a hollow container for storing the filth D discarded inside the film 15, and is divided into a storage body lower part 17 and a storage body upper part 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 openable / closable sealing mechanism 28 that sandwiches and blocks the film 15 between the filth inlet 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 inlet 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 pushed downward passes between the sealing door 33 opened with the film 15 and the sealing door receiving portion 35. The filth D passing through the sealing door 33 and the sealing door receiving portion 35 travels downward through the film 15 and is accumulated in the filth storage body 13. When the user drops filth below the sealing door 33 and the sealing door receiving portion 35 and removes his / her hand from the trash input 16, the sealing door 33 immediately closes and the film 15 is sandwiched. Further, a new film 15 is fed out from the filth input port 16, and the new film 15 portion 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 when the door is closed, and FIG. 5 is an enlarged cross-sectional view of the sealing mechanism 28 shown in FIG. 3 when the door is opened. It is an enlarged view.

  The waste disposal apparatus 11 includes an openable / closable 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. When the sealing door 33 is closed, the sealing mechanism 28 is engaged with the sealing door receiving portion 35 to sandwich the film.

  When the sealing door 33 and the sealing door receiving portion 35 are engaged, a door contact surface 33 c that contacts the sealing door receiving portion 35 is formed in the sandwiched portion of the sealing door 33. A receiving portion contact surface 35 c that contacts the sealing door 33 is formed in the sandwiched portion of the sealing door receiving portion 35. 33c and 35c have the shape which mutually meshes | engages and engages in a closed state.

  In a state where the sealing door 33 and the sealing door receiving portion 35 are closed, the sealing door receiving portion 35 is placed inside the storage body upper portion 19 so that the sealing door 33 covers and closes the filth input port 16 from below. Installation is fixed.

  A guide rail 37 for guiding the sealing door 33 to operate in the opening direction and the closing direction is attached and fixed to the inner wall of the upper portion 19 of the storage body. The guide rail 37 is attached and fixed below 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 the normal state, the film 15 is sandwiched between the sealing door 33 and the sealing door receiving portion 35 as shown in FIG.

  On the other hand, when the user pushes down the sealing door 33, the sealing door 33 advances in an opening direction away from the sealing door receiving portion 35. When the sealing door 33 is opened, the pinching of the film 15 is released as shown in FIG. 3, and the filth D can be put into the filth storage body 13.

  In the present embodiment, the side sectional shape of the door contact surface 33c and the receiving portion contact surface 35c formed when the sealing door 33 is closed and engaged with the sealing door receiving portion 35 is shown in FIG. As shown in FIG. 5, the L-shape formed on the sealing door 33 and the inverted L-shape formed on the sealing door receiving portion 35 are combined.

  FIG. 6A is an enlarged side cross-sectional view schematically showing the sandwiched shape of the L-shaped sealing door and the inverted L-shaped sealing door receiving portion of the present embodiment when the door is opened. FIG. 6B is an enlarged side cross-sectional view schematically showing the sandwiched shape of the L-shaped sealing door and the L-shaped sealing door receiving portion of the present embodiment when the door is closed.

As shown in FIG. 6, the door abutment surface 33c has a flat surface 33c ₁ that crosses the sealing door top forming a L-shaped corner of the right angle, the L-shaped corner of the right angle intersecting the plane 33c ₁ A plane 33c ₂ to be formed and a plane 33c ₃ that intersects the plane 33c ₂ and the lower surface of the sealing door to form a right-angled L-shaped corner portion.

Further, receiving the abutment surface 35c has a planar 33c ₁ abuts plane 33c ₁ and a plane parallel 35c _1, plane 35c ₂ which forms a plane 33c ₂ of the L-shaped corner of the contact plane 35c ₁ perpendicular When, and a surface 35c ₃ which forms a plane 33c ₃ the L-shaped corner of the contact plane 35c ₂ perpendicular.

When the sealing door 33 slides in the direction of the arrow shown in FIG. 6 (a) from the opened state shown in FIG. 6 (a) to the closed state shown in FIG. 6 (b), the film 15 is sandwiched. The film 15 is bent at right angles at two L-shaped corner portions of α ₁ and α ₂ . That is, the imaginary straight line connecting the sandwiched portion upper end β to the sandwiched portion lower end γ shown in FIG. 6B is bent in a substantially horizontal direction between α _{1 and} α ₂ .

  Here, the filth D discarded at the inner lower end of the film 15 is subjected to gravity downward due to its own weight. That is, the film 15 is always subjected to downward tension as shown by the white arrow in FIG.

When the film 15 is sandwiched with the tension applied as shown in FIG. 6B and the film 15 is bent at right angles at two L-shaped corners α ₁ and α ₂ , At the corner portion, the film 15 is further tensioned, and the residual ventilation path that causes odor transmission in the above-described prior art is blocked at a right angle. This can greatly improve the odor blocking ability.

  Moreover, since it is not necessary 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 being lowered.

  Further, when the sealing door 33 and the sealing door receiving portion 35 are mass-produced by molding, the L-shape and the inverted L-shape are easy to mold and have an advantage in mass production of products.

  Another embodiment of the sealing door 33 and the sealing door receiving portion 35 is shown in FIGS. FIG. 7A is an enlarged side cross-sectional view showing the sandwiched shape of the convex-shaped sealing door and the concave-shaped sealing door receiving portion according to another embodiment when the door is opened. FIG. 4B is an enlarged side sectional view showing a sandwiched shape of the convex-shaped sealing door and the concave-shaped sealing door receiving portion of the embodiment when the door is closed.

  In this embodiment, the side cross-sectional shape of the sandwiched portion between the sealing door 33 and the sealing door receiving portion 35 is formed on the convex shape formed on the sealing door 33 and the sealing door receiving portion 35. It is a combination with a concave shape that receives a convex shape.

  Specifically, a protrusion 133 having a convex cross section is formed on the door contact surface 33c. A groove 135 having a concave cross section is formed in the receiving portion abutting surface 35c. Further, the protrusion 133 protrudes in parallel with 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 to close the door, the sealing door 33 and the sealing door receiving portion 35 do not interfere with the sliding. The provided uneven shape is engaged.

As shown in FIG. 7, the constituent surfaces of the door contact surface 33c are 33c _{1 to} 33c ₅ , respectively, and the constituent surfaces of the receiving portion contact surface 35c are 35c _{1 to} 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 sandwiched portion upper end β to the sandwiched portion lower end γ shown in FIG. 7B.

Therefore, from the open state shown in FIG. 7A to the closed state shown in FIG. 7B, the sealing door 33 slides in the direction of the arrow shown in FIG. Then, the film 15 is bent at right angles at the four L-shaped corner portions of 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 .

Similar to FIG. 6, the dead weight of the filth D acts on the bent portions α _{1 to} α ₄ in the direction indicated by the white arrow. Therefore, a large tension is applied to the film 15 at the four L-shaped corner portions, and the residual ventilation path formed along the inner side of the film 15 is blocked at right angles, so that the odor can be blocked more reliably.

  Moreover, since it is not necessary to twist the film 15 for every disposal of filth, it is possible to prevent a decrease in the maximum amount of stored filth due to the twisted portion.

  Furthermore, when the sealing door 33 and the sealing door receiving portion 35 are mass-produced by molding, the uneven shape is easy to mold, and has an advantage in mass production of products.

  The waste disposal apparatus 11 further includes a spring 39 for always biasing 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 upper portion 19 of the storage main body, and forms an outline of the filth input port 16. The film storage part 14 is fitted and fixed to the cylindrical tubular core part 27 extending downward from the waste inlet 16, the tubular core flange 27 f provided at the lower end part of the tubular core part 27, and the upper end side of the tubular core part 27. And a flange-shaped film holding flange 29.

  The film 15 is folded in a bellows shape in the axial direction of the tubular core portion 27 and inserted so as to be coaxially disposed on the outer diameter side of the tubular core portion 27. A film holding flange 29 is fitted and connected to the tubular core portion 27 so as to prevent the film 15 from popping out.

  That is, the film 15 is formed 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, so that the film 15 is aligned with the axial upper end of the tubular core portion 27. The space between the lower end of the direction is folded in a bellows shape and compressed and stored.

  The film 15 is a consumable part of the film storage unit 14. When all the stored film is used, the used film storage unit 14 is removed and a new film storage unit 14 is set in the film attachment unit 12. .

  Preferably, after all the films 15 stored in the film storage unit 14 have been used, only the films may be replaced.

  In this setting operation, the user of the waste disposal apparatus 11 first pulls the leading end of the film 15 compressed and stored in the tubular core portion 27 with the lid 23 open so as to exceed the outer peripheral edge of the film holding flange 29. . 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 is drawn out one after another on the outer side of the tubular core portion 27. Since it extends downward, it becomes possible to dispose of the waste continuously into the waste storage body 13.

  As shown in FIG. 1 to FIG. 3, the waste disposal apparatus 11 of the present embodiment is a film so that the axial direction of the tubular core 27, that is, the opening direction of the waste inlet 16 intersects the vertical line at a predetermined angle. The storage portion 14 is supported by the storage main body upper portion 19. As a result, the filth input port 16 is provided inclined.

  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. Details of the sealing door upper surface 34 will be described later. In the waste disposal apparatus 11 of the present embodiment, the sealing door upper surface 34 corresponds to the inclined axial direction of the tubular core portion 27, and is supported by the storage main body upper portion 19 inclined at a predetermined angle intersecting the horizontal plane. 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 axial direction of the tubular core portion 27.

Specifically, as shown in FIG. 4, the inclination angle of the waste inlet 16 with respect to the vertical line (the tubular core 27) and theta _16, the inclination angle of the forward and backward direction S of the sealing door 33 with respect to the vertical line theta _{As 33} , the following expression (1) is satisfied.

0 ° <θ ₁₆ <θ ₃₃ (1)
According to the present embodiment, since the larger than the inclination angle theta ₁₆ of advance and retreat direction S of the inclination angle theta ₃₃ waste inlet 16 of the sealing door 33, the sealing door 33 is retracting the opening direction Therefore, it is possible to move away from the axis O of the tubular core portion 27, and the sealing door 33 can be sufficiently separated from the film 15 when the door is opened. Therefore, the film 15 is largely opened when the door is opened, and the user can easily drop the filth toward the filth storage body 13.

Although not shown in the drawing, it may be supported by the storage main body upper portion 19 so that the sealing door upper surface 34 is vertical (θ ₃₃ = 90 °). In this case, the sealing door 33 moves back and forth 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 many cases, the mother exchanges the infant's diaper with the mother sitting on the floor and the mother sitting on the floor. Therefore, according to the present embodiment, after changing the diaper while the mother is sitting, the used diaper (dirt) is put in the filth input port 16 while sitting, and the sealing door 33 is opened to open the filth storage body 13. It becomes easy to dispose of it inside.

  According to this embodiment, the film storage part 14 is supported by the storage main body upper part 19 so that the axial direction of the tubular core part 27 may intersect the vertical line at a predetermined angle. In addition, a sealing portion is provided so that a sandwiching portion by engagement between the sealing door 33 and the sealing door receiving portion 35 located below the film storage portion 14 is provided in the inclined lower side region on the lower surface of the tubular core flange 27f. A door receiving portion 35 is provided.

  Accordingly, the sealing door upper surface 34 is substantially flat, but strictly speaking, the upper surface front portion 34f of the sealing door upper surface 34 is a flat surface, and the upper surface rear portion 34f of the sealing door upper surface 34 becomes the upper surface front portion 34f. The shape is gently curved so as to be inclined.

  If it demonstrates along FIG. 4, the film accommodating part 14 is supported by the accommodating main body upper part 19 so that it may become the downward side of an inclination in the front. Further, the sealing door 33 sandwiches the film in cooperation with the sealing door receiving portion 35 on the front side, that is, on the inclined lower side. In other words, when the sealing door 33 is closed, the film abutting surface 33c and the receiving portion abutting surface 35c are interposed between the film accommodating portions 14 and 34f. The door contact surface 33c and the receiving portion contact surface 35c are not interposed between the portions 34r.

  Therefore, when the sealing door 33 is closed, the upper front portion 34 f adjacent to the sandwiching surface 33 c is separated downward from the film storage portion 14.

  On the other hand, a shape for sandwiching the film is not provided behind the sealing door 33. Therefore, when the sealing door 33 is closed, the upper surface rear portion 34 r is located in the vicinity of the lower end of the film storage portion 14. Accordingly, 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 rear portion 34r). Consists of

In the present embodiment, as shown in FIG. 4, the angle between the front upper portion 34f and the horizontal plane is θ _34f, and the angle between the upper rear portion 34r and the horizontal plane is θ _34r , and the following expression (2) is satisfied. Thus, a sealing door upper surface 34 is formed.

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. The sealing door 33 can be opened 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 a small force.

  In the present embodiment, as described above, the sealing door 33 is engaged with the sealing door receiving portion 35 on the front side, that is, on the inclined lower side, and the film is sandwiched therebetween.

  Here, the film 15 accommodated in the film accommodating 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 accommodated in the accommodating body lower portion 17 together with the filth D. Therefore, the film 15 is pulled down vertically by gravity applied to the waste D disposed inside the film 15.

Therefore, when the tubular core portion 27 is supported so as to be inclined downward on the front side, when the diameter of the waste inlet is L _O and the inclination angle from the horizontal direction is θ _O , the film 15 is at least a distance only _{L O (1-cosθ} O) as, 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. This facilitates the sandwiching of the film 15 by the sealing mechanism 28, and can be expected to have an effect of efficiently performing the sealing for blocking the odor.

  Next, the opening operation of the filth storage body 13 will be described.

  FIG. 9 is an overall perspective view showing the main body locking mechanism 25 and the lid body locking mechanism 24 of the present embodiment, and FIG. 10 is an overall perspective view of the waste disposal apparatus 11 of the present embodiment as viewed from the back oblique direction. FIG. 11 is an enlarged side sectional view showing the main body locking mechanism 25 and the lid locking mechanism 24 in an enlarged manner.

  In the normal state of use, the waste disposal apparatus 11 has the storage body upper portion 19 and the storage body lower portion 17 closed so that the storage body upper portion 19 covers the main body opening 17h at the upper end of the storage body lower portion 17 on the lower end side.
