Film storage cassette for dirt disposal apparatus {STORING CASSETTE OF FILM FOR GARBAGE DISPOSAL}

This invention relates to the film storage cassette used for the waste disposal apparatus for discarding used dirt, such as a used baby diaper.

In a waste disposal apparatus for disposing of waste such as used baby diapers, when the waste is continuously fed into the waste disposal apparatus from the viewpoint of cleanliness and convenience, the film for storing the waste is sequentially released to the waste inlet. Film storage cassettes are widely used. Japanese Patent No. 4402165 (Patent Document 1) is disclosed as a prior art relating to a film storage cassette used in such a waste disposal apparatus.

The film storage cassette described in Patent Literature 1 includes an inner wall partitioning a circumferential core portion, a bottom wall extending radially outward from a lower end of the inner wall, an outer wall extending upward from the outer edge of the bottom wall, and an inner wall. It has a flange part extended toward an outer wall side from an upper end. The film for accommodating dirt is folded and accommodated in a wrinkled box shape in the film storage space partitioned by an inner wall, a bottom wall, an outer wall, and a flange part. On the outer wall of the film storage cassette, an annular cassette flange portion protruding from the outer wall surface toward the outer side is provided.

On the other hand, the annular film cassette rotating apparatus is rotatably attached to the small chamber provided in the upper part of the main body of the waste disposal apparatus. On the inner wall surface of this film cassette rotating apparatus, the annular rotating apparatus flange part which protrudes toward an inner side from the inner wall surface is provided. When the film storage cassette is set in the film cassette rotating apparatus, the cassette flange portion is placed on the rotating apparatus flange portion, so that the film storage cassette is supported by being suspended in the film cassette rotating apparatus. In this way, the film storage cassette described in Patent Document 1 can be easily set in the waste disposal apparatus main body by placing in the film cassette rotating apparatus.

Patent Document 1: Japanese Patent No. 4402165

The main body of a general waste disposal apparatus is divided into the lower part of the accommodating main body which stores a dirt, and the upper part of the accommodating main body with the said film accommodating cassette. And the upper part of a storage main body is attached to the lower part of a storage main body, or is detachably attached. When the inside of the waste accommodating main body is filled with the stored dirt, the user rotates and opens the accommodating main body upper part, or removes the accommodating main body upper part from the accommodating main body lower part, and performs the operation of taking out the dirt stored in the main body.

In such a case, the film storage cassette described in Patent Document 1 has the following problems. That is, the film storage cassette of patent document 1 is supported so that it may be suspended in the inside of a film cassette rotating apparatus as mentioned above. According to this configuration, in the above-mentioned waste taking out operation, when the user inadvertently tilts the upper part of the storage main body when the upper part of the storage main body is opened by rotating the housing main body or when the upper part of the storage main body is removed, There is a possibility that the storage cassette easily pops out of the waste disposal apparatus main body. Therefore, when the user performs the dirt take-out work, it is necessary to pay attention to the sticking out of the film storage cassette, so handling is difficult.

Thus, the structure which a film cassette can fall easily from the waste disposal apparatus main body is not preferable from a handling point of view and a sanitary point of view.

Moreover, since the film storage cassette of patent document 1 has an inner wall, a bottom wall, an outer wall, and a flange part, a structure is complicated and the raw material used for manufacture also increases. Therefore, there is also a problem that leads to an increase in manufacturing cost.

In view of the above-described problems, an object of the present invention can be easily set in a waste disposal apparatus, and, when set, can prevent falling from the waste disposal main body and reduce manufacturing costs. It is to provide a film storage cassette.

The film storage cassette according to the present invention is detachably attached to a film attachment portion formed on an upper portion of a waste treatment apparatus for storing waste, and has a cylindrical tubular core portion that forms a waste inlet at an upper end, and a lower end portion of the tubular core portion. The lower flange extending radially outwardly from the upper portion of the tubular core and extending radially outwardly from the upper end of the tubular core, while accommodating the film in the compressed state between the lower flanges, It only has an upper flange that allows it to be loosened in the tubular core. Here, the lower flange has a cassette-side locking portion that engages with the film attachment portion and connects the film storage cassette to the film attachment portion.

According to this configuration, since the cassette-side locking portion provided in the lower flange engages with the film attachment portion, the film storage cassette can be reliably connected to the waste disposal apparatus main body. As a result, the upward movement of the film storage cassette is prevented, so that the film storage cassette can be prevented from escaping from the waste storage main body even if the user tilts the waste storage main body in the dust extraction operation as described above. have. In addition, since the cassette side locking portion is provided only in the lower flange of the film storage cassette, it is possible to prevent the film accommodated in the film storage cassette from being damaged in contact with the cassette side locking portion at the time of use of the waste disposal apparatus. Moreover, this film storage cassette consists only of a tubular core part, an upper flange, and a lower flange, and is a structure which uses the inner wall surface of a film attachment part as a member corresponded to the outer wall in the conventional cassette. Thus, since the film storage cassette which concerns on this invention is a very simple structure, since a metal mold | die cost, raw materials, etc. can be reduced, manufacturing cost can be held down.

Preferably, the cassette-side locking portion includes a protrusion that protrudes outward in the radial direction as part of the lower flange. Alternatively, the cassette-side locking portion may include a notch that is recessed inward from the outer edge of the lower flange in the radial direction.

According to this configuration, the user can connect the film storage cassette to the film attachment portion by the following simple operation. That is, the user matches the position of the main body side locking part provided in the film attachment part, and the position of the protrusion part or notch provided in the outer edge part of the lower flange. Subsequently, the film storage cassette is pushed into the film attachment portion. Finally, the film storage cassette is rotated in the circumferential direction. By such a series of simple operations, the film storage cassette can be connected to the film attachment portion. In addition, the cassette-side locking portion is constituted by the concave-convex shape formed in the lower flange without using a new member separately. Therefore, the manufacturing cost of a waste disposal apparatus can be reduced.

Preferably, the protrusions or notches are provided in plural places and are arranged at equal intervals in the circumferential direction with respect to the central axis of the tubular core.

According to this structure, the film storage cassette can be connected to a waste storage main body by the protrusion part provided in several places, or the main body side latching part provided so that it may correspond with the notch. Therefore, even when a large force acts by the direction which removes a film storage cassette from a waste storage main body, this can be suppressed effectively. In addition, since the protrusions or the main body side locking portions provided in a plurality of places are arranged at equal intervals in the circumferential direction, the force applied to the individual locking members can be reduced and evenly distributed, thereby effectively preventing them from being damaged. Can be.

Preferably, the cassette-side locking portion further includes an engagement rib extending radially inward from the outer edge of the lower flange on the upper surface of the lower flange. Here, the engagement ribs have a function of connecting the film storage cassette to the film attachment portion and engaging the main body side locking portion to regulate the rotation of the film storage cassette when the film storage cassette is rotated in the circumferential direction.

More preferably, the engagement rib is a first engagement rib disposed at one end of the notch in the circumferential direction, and a second rib spaced apart from the first engagement rib at the other distance in the circumferential direction at a predetermined distance. It is comprised by the engagement rib. Here, when the main body side engaging portion and the first engagement rib are in contact with each other, the positions of the main body side engaging portion and the notch coincide, so that the film storage cassette can be detached from the film attaching portion, and the main body side engaging portion and the In the case where the engagement ribs of 2 are in contact with each other, the main body side locking portion and the outer edge of the lower flange engage with each other to prevent the upward movement of the film storage cassette.

According to this structure, a film storage cassette arranges a film storage cassette in a film attachment part, rotates a film storage cassette to one side in the circumferential direction, and becomes a connection state when rotation is regulated. In addition, the film storage cassette is rotated to the other side in the circumferential direction, so that the film storage cassette is in a disconnected state when the rotation is restricted. That is, since the user can easily determine the state of the connection / disconnection, the attaching and detaching operation of the film storage cassette can be made easier.

Preferably, on the upper surface of the lower flange, at a predetermined position radially inward from the left edge of the lower flange, an annular rib extending continuously in the circumferential direction about the center axis and connected to the engagement rib, and a tubular shape A plurality of radial ribs extending radially from the core portion to the annular ribs are provided.

According to this structure, the intensity | strength of a lower flange can be improved by the said rib provided in the upper surface of a lower flange. Moreover, since the film accommodated in the film storage cassette is arrange | positioned on the said rib, a clearance gap is formed between the lower flange upper surface and a film by the height of a perpendicular direction of a rib. Therefore, when the film storage cassette is connected to the film attachment portion, the main body side locking portion enters this gap, so that interference between the main body side locking portion and the film can be prevented. Therefore, the film can be prevented from being damaged by the main body side locking portion.

According to the film storage cassette according to the present invention, since the cassette-side locking portion provided in the lower flange engages with the film attachment portion, the film storage cassette can be reliably connected to the waste treatment apparatus main body. Thereby, since the movement to the upper direction of a film storage cassette is prevented, even if a user inclines the waste storage main body in a waste extraction operation as mentioned above, it can prevent that a film storage cassette escapes from a waste storage main body. In addition, since the cassette side locking portion is provided only in the lower flange of the film storage cassette, it is possible to prevent the film contained in the film storage cassette from being damaged in contact with the cassette side locking portion at the time of use of the waste disposal apparatus. Moreover, this film storage cassette consists only of a tubular core part, an upper flange, and a lower flange, and the inner wall surface of a film attachment part can be used as a member corresponded to the outer wall in a conventional cassette. Thus, since the film storage cassette which concerns on this invention is a very simple structure, since a metal mold | die cost, raw materials, etc. can be reduced, manufacturing cost can be held down.

In the normal state, as shown in FIG. 2, the film 15 is sandwiched by the sealing door 33 and the sealing door receiving part 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 falling from the sealing door receiving part 35. As shown in FIG. When the sealing door 33 opens, as shown in FIG. 3, the insertion of the film 15 is canceled | released and the dirt D can be thrown in into the waste storage main body 13. As shown in FIG.

In this embodiment, as shown in FIGS. 2-5, the sealing door 33 and the sealing door receiving part 35 are provided with the pair of uneven | corrugated shape which engages with each other at the time of closing. And the film 15 is sandwiched by the uneven | corrugated shape provided in the sealing door 33 and the sealing door receiving part 35. As shown in FIG. The uneven | corrugated shape provided in the sealing door 33 is comprised by the insertion surface 33c which contact | connects the film 15 at the time of closing. Moreover, the uneven | corrugated shape provided in the sealing door receiving part 35 is comprised by the fitting surface 35c which contact | connects the film 15 at the time of closing.

Here, the fitting surface 33c, 35c is demonstrated in detail below using FIG. FIG. 6 (a) is a side cross-sectional enlarged view schematically showing an enlarged and schematic view of a film sandwiching portion at the time of opening the sealing door 33 and the sealing door receiving part 35 according to the present embodiment. FIG. 6 (b) is a side cross-sectional enlarged view schematically showing an enlarged and schematic view of a film sandwiching portion during closing of the sealing door 33 and the sealing door receiving part 35 according to the present embodiment. In addition, since FIG. 6 has shown typically the film insertion part of the sealing door 33 and the sealing door receiving part 35 for ease of understanding, the detailed structure differs from actual embodiment. different.

As shown in FIG.6 (a) and FIG.6 (b), the insertion surface 33c corresponding to the film insertion part of the sealing door 33 is the front end of the upper surface of the sealing door 33 ( surface forming前端) and the surface (33c ₁₎ corresponding to an area, surface (33c ₁₎ and connected to the surface (33c ₁₎ and a schematic right angle from the front end increasing downward face (33c ₁₎ and the edge portion of an approximately right angle in (33c ₂₎ and a surface (33c ₂₎ connected to the face (33c ₂₎ and a schematic right angle from the bottom of the rise to the front side, consists of a face (33c ₂₎ and the surface (33c ₃₎ of forming corner portions of an approximately right angle .

Moreover, the insertion surface 35c corresponding to the film insertion part of the sealing door receiving part 35 is provided so that it may become substantially orthogonal to the axis O of the waste inlet 16 at the upper end of the film insertion part, surface on which the surface (33c ₁₎ and a schematic parallel when CLOSING (35c ₁₎ and, connected at the front end of the surface (35c ₁₎ to the surface (35c ₁₎ and a schematic right angle increasing downward surface during CLOSING (33c ₂ ) and connected to the face (35c ₂₎ and a surface (35c ₂₎ and a schematic right angle from the bottom of the face (35c ₂₎ is the schematic parallel increases toward the front, side when CLOSING that this surface (33c ₃₎ and a schematic parallel It consists of 35c ₃ .

The sealing door 33 slides toward the direction of the arrow in FIG. 6 (a) from the opening state shown in FIG. 6 (a), sandwiches the film 15, and closes the door shown in FIG. 6 (b). When it is in a state, the film 15 is bent at approximately right angles at two corner portions of α ₁ and α ₂ . That is, the up-down direction intermediate point (alpha) ₁ , (alpha) ₂ in the part to which the film 15 which inserted was inserted by the sealing door 33 and the sealing door receiving part 35 is shown, FIG. It is bend | folding to the side with respect to the virtual straight line which connects the upper end (beta) and the lower end (gamma) of the interposed part of the film shown by the dashed-dotted line in 6 (b). Moreover, the film 15 is also bent at the upper end β of the film sandwiching portion by the corner portion formed at the rear end of the surface 35c ₁ . Similarly, the film 15 is bent at the lower end γ of the film sandwiching portion by the corner portion formed at the front end of the surface 33c ₃ .

Here, the dirt D discarded inside the film 15 is gravity gravityd downward by its own weight. That is, the tension 15 always acts vertically downward by the dirt D on the film 15. When the film 15 in the state where such tension acts is inserted as shown in FIG. 6 (b), and the film 15 is bent at four corner portions of α ₁ , α ₂ , β, and γ, At this corner, a greater tension is applied to the film 15. Thereby, the residual ventilation path | route which becomes a factor which transmits an odor in the above-mentioned prior art is effectively interrupted | blocked. Therefore, the blocking of odors can be greatly improved. Moreover, since there is no need to twist a film for every waste disposal, the fall of the maximum dirt storage amount by a gap part can be prevented. In addition, when mass-producing the sealing door 33 and the sealing door receiving part 35 by metal mold | die shaping, the uneven | corrugated shape which has a roughly right angled corner | corner shape is a step shape and it is not a complicated shape especially. Therefore, molding is easy. Thus there is an advantage with regard to mass production of the product.

Other embodiment of the sealing door 33 and the sealing door receiving part 35 is shown typically in FIG.7 (a) and (b). FIG. 7 (a) is an enlarged side cross-sectional view showing an enlarged portion of a film sandwiching portion at the time of opening the spell-closing door and the recess-shaped sealing door receiving part according to another embodiment. FIG. 7 (b) is an enlarged side cross-sectional view showing an enlarged portion of the film sandwiching at the time of closing the spell-closing door and the recess-shaped door receiving part according to the embodiment; FIG. In addition, since FIG. 7 has shown typically the film part of the sealing door 33 and the sealing door receiving part 35 for ease of understanding, a detailed structure differs from actual embodiment. different.

In this embodiment, the sealing door 33 in which the insertion of the film 15 by the sealing door 33 and the sealing door receiving part 35 is provided with the film insertion part which has a lateral side cross section of the letter shape is provided. And the sealing door receiving part 35 provided with the film-insertion part which has the concave-shaped side cross section which receives the spelling shape provided in the sealing door 33 is implemented.

Specifically, cross-sectional spelling projections 133 are formed on the fitting surface 33c. Moreover, the groove-shaped groove | channel 135 of cross section concave shape is formed in the surface 35c to be fitted. The protrusion 133 protrudes so that it may become substantially parallel with the sliding direction of the door 33 for sealing. Therefore, when the sealing door 33 slides toward the closing direction and engages with the sealing door receiving part 35, the sealing door 33 is provided in the sealing door 33 and the sealing door receiving part 35 without impeding the sliding. Concave-convex shapes engage.

7, the surface constituting a surface (33c) telescoping formed in a closed door (33) are, respectively, 33c ₁ to 33c _5. In addition, the surface forming the surface (35c) formed in telescoping sealing door receiving portion (35) are, respectively, 35c ₁ to 35c _5. Among these constituent surfaces, 33c ₂ and 33c ₄ and 35c ₂ and 35c ₄ are planes orthogonal to an imaginary straight line connecting the upper end β to the lower end γ of the film insertion portion shown in FIG. 7B. to be. Therefore, the sealing door 33 slides toward the direction of the arrow in FIG. 7 (a) from the opening state shown in FIG. 7 (a), sandwiches the film 15, and closes the door shown in FIG. 7 (b). When it is in a state, the film 15 is bent at approximately right angles at four corner portions of α ₁ to α ₄ . That is, the film 15 is bent in the approximately horizontal direction between α ₁ to α ₂ and α ₃ to α ₄ .

Similar to FIG. 6 mentioned above, gravity downward acts on the film 15 by the self weight of the dirt D. As shown in FIG. Therefore, a large tension is applied to the film 15 at these four roughly right corners. Thereby, the residual ventilation path formed along the inside of the film 15 is bent at a right angle, and the odor can be blocked more effectively. In addition, since there is no need to twist the film 15 for every waste disposal, the fall of the maximum dirt storage amount by a gap part can also be prevented. In addition, when mass-producing the sealing door 33 and the sealing door receiving part 35 by mold molding, since the uneven | corrugated shape is easy to shape | molding, there exists an advantage also in the mass production of a product.

Moreover, the waste disposal apparatus 11 is further equipped with the spring 39 for adding the sealing door 33 to the direction of the sealing door receiving part 35 at all times. The greater the force of the spring 39, the greater the force for sandwiching the film 15, and the more the odor barrier property can be improved.

FIG. 8 is an exploded perspective view showing the film accommodating portion 14 removed. The waste disposal apparatus 11 is equipped with the film accommodating part 14 which accommodates the film 15 while forming the waste inlet 16. This film accommodating part 14 is detachably attached to the film attachment part 12 provided above the accommodating main body upper part 19, and forms the outer periphery of the waste inlet 16. As shown in FIG. The film accommodating portion 14 includes a cylindrical tubular core 27 extending downward from the waste inlet 16, a tubular core flange 27f provided at the lower end of the tubular core 27, It has the flange-shaped film press flange 29 which penetrates into the upper end side of the tubular core part 27, and is fixed.

The film 15 is inserted in the axial direction of the tubular core 27 to be folded into a corrugated box shape, and inserted into the outer diameter side of the tubular core 27 so as to be coaxially disposed. And the film pressing flange 29 is connected to the tubular core part 27 so that the jumping out of the film 15 may be carried out. That is, the film 15 is tubular by the film press flange 29 located in the upper end of the tubular core 27, and the tubular core flange 27f located in the lower end of the tubular core 27. In the space between the upper end of the core part 27 direction of the axis line O, and the lower end of the axis line O direction, it is folded and compressed and accommodated in the shape of a pleat box.

The film 15 is a consumable part of the film accommodating portion 14, and when all of the contained films are used, the user removes the used film accommodating portion 14 to film the new film accommodating portion 14. It is set to the attachment part 12. Or the film accommodating part 14 may be the structure by which only the film is replaced, when all the films 15 accommodated in the film accommodating part 14 are used. That is, the structure in which the tubular core flange 27f is fixed to the film attachment portion 12 and the film pressing flange 29 is detachably attached to the tubular core portion 27 may be employed. According to this structure, at the time of film replacement, a user can remove the film press flange 29 and replace only a film.

After setting the film accommodating part 14 to the waste disposal apparatus 11, a user presses the front-end | tip of the film 15 compressed and accommodated in the tubular core part 27 with the cover 23 opened, and a film press flange Draw upwards beyond the outer periphery of (29). Subsequently, the drawn tip is closed by a knot 26. Then, the knot 26 is inserted into the tubular core 27 to be pushed downward, and the knot 26 is pushed to the bottom 17b while releasing the film 15 from the film accommodating portion 14. When the wastes such as used diapers and the like are discarded inside the film 15, the dirt is accumulated in the film 15, and the film 15 folded in a pleated box shape on the outer diameter side of the tubular core portion 27. This is released in turn and increases downward. Therefore, the user can dispose of the waste in the waste storage main body 13 continuously.

As shown in FIG. 4, in the waste disposal apparatus 11 of this embodiment, the direction of the axis O of the tubular core part 27, ie, the opening direction of the waste inlet 16, is inclined at a predetermined angle. The film housing portion 14 is supported by the housing body upper portion 19. The dirt inlet 16 is inclined at a predetermined angle θ ₁₆ from the vertical direction toward the front side. This makes it easy for the mother to dispose of the diaper of the infant. This is briefly described below. In general, the work of the mother changing the diaper of the infant is often performed while the infant is lying on the floor and the mother is sitting. Therefore, according to the present embodiment, since the waste inlet 16 is inclined at a predetermined angle θ ₁₆ , the mother sits and replaces the diaper of the infant, and the used diaper (filtrate) is used as the waste inlet. The work discarded at 16 becomes easy.

In addition, although not shown in figure, the film accommodating part 14 may be supported by the accommodating main body upper part 19 so that the opening direction of the waste inlet port 16 may be horizontal. In this case, the axis O of the tubular core 27 extends horizontally. This is because even in such a case, tension can be applied to the embedded film portion.

4 and 5, the sealing door 33 has an approximately flat sealing door upper surface 34. The detailed shape of the sealing door upper surface 34 is mentioned later. In the waste disposal apparatus 11 of this embodiment, the sealing door 33 is accommodated so that the sealing door upper surface 34 may incline at the predetermined angle corresponding to the axial direction which the tubular core part 27 inclined. It is supported by the upper body 19. That is, the sealing door 33 is inclined at a predetermined angle so that the front end side becomes a low position in the vertical direction and the rear end side becomes a high position in the vertical direction while the closing door 33 is closed. 19). And the sealing door 33 moves forward and backward at a predetermined angle toward the sealing door receiving part 35. The advancing and moving direction S of the sealing door 33 is inclined at an angle different from the axis O of the tubular core 27.

Specifically, as shown in FIG. 4, the inclination angle of the dirt inlet 16 (tubular core 27) with respect to the vertical direction is set to θ ₁₆ , and the retraction of the sealing door 33 with respect to the vertical direction is made. The following expression (1) is satisfied by setting the inclination angle of the movement direction S to θ ₃₃ .

0 ° <θ ₁₆ <θ ₃₃ ‥‥ (1)

According to this present embodiment, the inclination angle θ ₃₃ of the advancing and moving direction S of the sealing door 33 is larger than the inclination angle θ ₁₆ of the waste inlet 16. Thereby, as the sealing door 33 retreats to an opening direction, the sealing door 33 moves downward and parallel to back, and it moves from the axis O of the tubular core part 27. Away. That is, the opening door 33 can be fully separated from the film 15 at the time of opening. Therefore, since the film 15 is largely opened at the time of opening, the user can easily dispose of the dirt toward the waste storage main body 13 in a sitting state.

In addition, although not shown in figure, the sealing door 33 may be supported by the upper part 19 of the storage main body so that the sealing door upper surface 34 may be perpendicular (θ ₃₃ = 90 °). In this case, the sealing door 33 moves forward and backward in the horizontal direction. If this is the case, the opening door 33 can be effectively separated from the film 15 at the time of opening.

Moreover, according to this embodiment, the tubular core flange 27f corresponding to the lower end of the film accommodating part 14 arrange | positioned so that the lower end of the tubular core part 27 may incline at the predetermined angle may be a waste accommodating main body. It is supported by (13). That is, as shown to FIG. 2 to FIG. 5, the front end side of the tubular core flange 27f is at a low position in the vertical direction, and the rear end side is at a high position in the vertical direction. And the surface 35c of the sealing door receiving part 35 is arrange | positioned in the vicinity of the lowest position of the tubular core flange 27f. Thereby, the insertion of the film 15 by the sealing door 33 becomes easier. This will be described below.

The film 15 housed in the film accommodating portion 14 so as to be released from the dirt inlet 16 passes vertically downward through the inside of the tubular core portion 27, and together with the dirt D, the lower part of the accommodating main body. It is stored in 17. Therefore, when the sealing door 33 is opening, since the film 15 is pulled vertically downward by the weight of the waste D discarded in the inside of the film 15, from the waste inlet 16 It is serialized almost straight down. Here, the tubular core 27 is inclined at a predetermined angle θ ₁₆ as described above. Therefore, when the diameter of the waste inlet 16 is set to LO and the inclination angle of the waste inlet 16 with respect to the horizontal direction is θ _O (= θ ₁₆ ), the film 15 is directly below the waste inlet 16. When it is extended, at least as a horizontal distance, L ₀ (1-cosθ _O ) is naturally closer to the forward inclined downward side. Thus, the film 15 is sandwiched by the sealing door 33 and the sealing door receiving part 35 from the inclination downward side naturally approaching. Thereby, since insertion of the film 15 by the sealing door 33 can be made easier, sealing for odor blocking can be performed more efficiently.

In addition, in the present embodiment, as described above, the sealing door upper surface 34 is formed to be substantially flat, but, strictly, the sealing door upper surface 34 is an upper surface front part 34f which is an approximately flat surface. ) And an upper surface rear portion 34r that is gently curved to incline with respect to the upper surface front portion 34f. This will be described with reference to FIG. 4. As mentioned above, the film accommodating part 14 is supported by the accommodating main body upper part 19 so that it may be inclined downward side from the front. In addition, the sealing door 33 engages with the sealing door receiving part 35 on the front side, ie, the inclined lower side, and sandwiches the film. Here, at the time of the closing of the sealing door 33, the surface 35c of the sealing door receiving part 35 is interposed between the film accommodating part 14 and the upper surface front part 34f.

On the other hand, between the film accommodating part 14 and 34 r of upper surface back surfaces, the surface 35c of the sealing door receiving part 35 is not interposed. For this reason, the sealing door upper surface 34 is in contact with the sealing door receiving part 35 so as to close the waste inlet from below, so that two different surfaces (the upper surface front part 34f of the flat surface and the inclined surface) Top rear part 34r).

In this embodiment, as shown in FIG. 4, the angle between the upper surface front part 34f and the horizontal plane is θ _34f , and the angle between the upper surface rear part 34r and the horizontal plane is θ _34r . The sealing door upper surface 34 is formed so that Formula (2) may be satisfied.

0 ° ≤θ _34f <θ _34r ‥‥ (2)

Thereby, when a user pushes open the sealing door 33 to dispose of the dirt, it can transmit pressure to the sealing door 33 efficiently by hand pressing on the upper back part 34r. . Therefore, the user can open the sealing door 33 with less force.

In addition, as a modification of this embodiment, the upper surface back part 34r and the advancing and moving direction S may be substantially orthogonal. According to this modification, the closing door 33 can be input to the spring 39 without attenuating the pressure received from the user's hand at all. Therefore, the user can push the sealing door 33 with less force.

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