Description

  The present invention relates to a waste storage device, and more particularly, to a waste storage device including a container having a container opening and a lid that is rotatably attached to the container and opens and closes the container opening. The waste storage device further comprises a drive ring rotatably mounted in the region of the container opening, the drive ring being a waste storage bag or tubular vinyl (through a central opening of the drive ring) It is configured to lock the waste storage hose). The waste storage device further includes a rack rod that is interlocked with the drive ring, and the first end of the rack rod is movably guided into the container. The invention further relates to a waste storage system comprising a waste storage device of the type described above and a storage cassette containing a waste storage bag, i.e. tubular vinyl.

  Waste storage devices of the type described above are generally known and are used for throwing away all sorts of waste, in particular for baby and / or adult diapers, and / or other personal waste. Is done. When the waste storage device is opened to throw away new waste, the bad odor resulting from some waste that has already been thrown out leaks from the device, making it quite uncomfortable for many users.

  For example, U.S. Patent Application No. 2002/0162304 A1 discloses a waste storage device comprising an arcuate rack bar secured to a container lid. When the lid is activated, the tubular vinyl that receives the waste is automatically twisted to trap the malodor inside. However, if this twist is not sufficient, the user cannot directly twist the tubular vinyl directly. Since the lid can only be moved up and down to twist the tubular vinyl further, it is very inconvenient for the user. To make matters worse, the movement of the lid creates an air flow and a bad odor is emitted from the container into the room.

  U.S. Pat. No. 8,215,089 and U.S. Patent Application Publication No. 2010/0005762 disclose automatically prior art waste storage devices with similar drawbacks as further prior art.

  U.S. Pat. No. 9,102,467 discloses a waste storage container further comprising means for twisting the waste storage tubular vinyl. Specifically, a drive ring that locks and twists the cylindrical vinyl is actuated by the foot pedal. This waste storage container is inconvenient because the cylindrical vinyl is not automatically twisted when the waste is discarded, and the cylindrical vinyl is twisted by another operation of pressing the foot pedal. Furthermore, if the foot pedal is not pressed immediately after throwing away the waste, the odor may leak out of the tubular vinyl without being trapped.

  German Utility Model Registration No. 202005015117 and German Utility Model Registration No. 202006004159 with similar drawbacks disclose a similar solution to US Pat. No. 9,102,467. German utility model registration No. 202005015117 and German utility model registration No. 202006004159 disclose push rods instead of foot pedals for twisting and closing the tubular vinyl.

  Accordingly, it is an object of the present invention to provide a waste storage device and a waste storage system that improve the sealing of cylindrical vinyl for waste storage and better prevent odor leakage. In particular, the waste storage device of the present invention automatically operates when the lid is opened and closed, but can also be manipulated accurately and intentionally as required.

  The object of the invention is solved by the waste storage device described in the opening paragraph. The rack bar of the apparatus faces the lid of the apparatus at the second end, which is the free end of the rack bar, and cooperates with the lid.

  As the lid moves, the rack bar and drive ring move, and the waste storage tubular vinyl is twisted and closed. That is, the movement of the lid causes movement of the rack bar and the drive ring, and further causes twisting and blockage of the waste storage tubular vinyl.

  Furthermore, the object of the present invention is solved by a waste storage system comprising a waste storage device of the type described above and a storage cassette containing waste storage bags, i.e. cylindrical vinyl.

  Advantageously, the rotation of the drive ring that occurs when the lid is opened and closed causes the waste storage bag or tubular vinyl to be automatically twisted and closed. On the other hand, the lid closes the container opening to provide a deodorizing function. On the other hand, when the lid pushes the rack bar downward, the waste storage bag, i.e., the tubular vinyl, is twisted to provide a deodorizing function. In this way, malodor can be trapped in the waste storage bag, that is, in the tubular vinyl. Further, for example, if the user thinks that the automatic twisting by the lid is insufficient, the user can push the second end, which is the free end of the rack bar, without moving the lid, Thereby, the drive ring is pushed, and the rack bar can be intentionally operated.

  In general, the drive ring may be actuated and rotated without direct touching the waste storage bag / cylindrical vinyl passed by the user through the drive ring or the central opening of the drive ring.

  Further advantageous embodiments are set forth in the appended claims as well as in the drawings.

  In one advantageous embodiment of the invention, the drive ring comprises a tooth or ring gear that is associated with the rack bar. In this way, the movement of the rack bar is converted into the rotation of the drive ring.

  It is particularly advantageous that the drive ring comprises a toothed or annular gear that cooperates with a bevel gear wheel, the bevel gear interlocking with a gear that cooperates with the rack bar. The movement of the lid causes movement of the rack bar, the gear cooperating with the rack bar, the bevel gear and the drive ring, and the waste storage tubular vinyl is twisted and closed. By these proposed methods, the moving direction of the rack bar can be made parallel to the rotation axis of the drive ring. Thus, the rack bar may be actuated from the top when the direction of travel and the axis of rotation of the drive ring are arranged vertically.

  In yet another advantageous embodiment, the rack bar is interlocked with a one-way clutch unit. In particular, the bevel gear of the above-described embodiment may include a one-way clutch device. However, the one-way clutch device may be used for another gear of the drive mechanism. With this one-way clutch device, for example, when the rack bar moves back and forth or up and down, it is possible to prevent the twist of the waste storage bag, that is, the cylindrical vinyl. The one-way clutch device may include a ratchet mechanism that performs the above-described function. However, it is particularly advantageous if the one-way clutch device utilizes friction. One-way clutch devices that utilize friction typically include a spring-biased roller that is disposed between the inner driven shaft and the outer sleeve. Specifically, the roller is disposed in a wedge-shaped or tapered notch portion of the shaft, and the inner peripheral surface of the outer sleeve prevents the roller from coming off from the notch portion. When rotating in one direction, the roller is caught in a tapered space between the notch and the inner peripheral surface of the sleeve, and the shaft and the sleeve rotate together. When the shaft rotates in the other direction, the roller simply slides on the inner circumferential surface of the sleeve. In this case, the sleeve is stationary even when the shaft rotates. A particular advantage of one-way clutch devices that utilize friction is that they operate very quietly and are hardly audible. In this way, the user of the waste storage device and the infant (sleeping) are not bothered by the sound of the waste storage device.

  Applying a one-way clutch device utilizing friction to the waste storage device is without the limitations of claim 1, i.e. the rack bar cooperates with the lid at the second end which is the free end. Note that it is useful even if not. Therefore, the application of a one-way clutch device that utilizes friction in a waste storage device can form the basis of an independent invention. In that case, the drive for the drive ring may have a different configuration. For example, the rack bar may be fixed to the lid or may be rotatably attached to the lid. The rack bar may be arranged at a distance from the lid. The rack bar may be arranged at another position, for example, may be arranged horizontally, or may be arranged to penetrate the side wall of the waste storage device. Furthermore, the rack bar is not necessarily required, and the one-way clutch device that uses friction may be used in combination with a crank that drives the drive ring. This independent invention can be defined as follows.

Waste storage equipment
-A container having a container opening;
-A drive ring rotatably mounted in the area of the container opening and configured to lock a waste storage bag or tubular vinyl passed through the central opening;
A drive for a drive ring having a one-way clutch device utilizing friction.

  In an advantageous embodiment of the invention, the rack bar is straight / straight. Since the rack bar is pushed in a linear motion, the user can easily operate it. Furthermore, the production of linear / straight rack bars is relatively easy. Thus, the proposed waste storage device of the present invention can be realized by simple technical means.

  In yet another advantageous embodiment, the rack bars are arranged vertically. Thus, the rack bar is pushed downward to operate the torsion mechanism. The user can also easily move downward.

  Furthermore, in an advantageous embodiment of the waste storage device, the rack bar is arranged opposite the hinge for attaching the lid to the container. For this reason, the movement distance of the rack bar is relatively long. Thereby, the apparatus can be operated with a light force, and the torsion mechanism can be easily operated.

  In yet another advantageous embodiment, the actuated rack bar may be spring biased to automatically move to the idle position. Therefore, since the torsion mechanism operates simply by pushing or pulling up, there is no need to reciprocate the rack bar.

  The drive ring is advantageously driven manually during operation, either directly or indirectly. In this way, the need for a connector to the power supply or power system can be eliminated. However, the drive ring may be driven directly or indirectly by a (electric) motor as well.

  Advantageously, the drive ring comprises a funnel with an elastic flap / lid. Therefore, it becomes easy to throw the waste into the waste storage bag, that is, the cylindrical vinyl. In addition, the elastic flap / lid returns to the idle position after the waste is discarded, so that the waste storage bag or tubular vinyl is closed even before the drive ring rotates.

  In a further advantageous embodiment, the waste storage device comprises a fastener attached to the container, the fastener being configured to secure a waste storage bag or tubular vinyl. In this way, the waste storage bag, that is, the blockage due to twisting of the cylindrical vinyl is improved.

  In a further advantageous embodiment, the waste storage device comprises at least one binding device for holding the cylindrical vinyl when tying the cylindrical vinyl, and the binding device is provided with a notch therebetween. It has two pin-like parts. By these means, the tubular vinyl is easily tied. To make a knot, the tubular vinyl is wrapped around two pins and passed through the formed loop via between the pins. This can be easily done with one hand. Therefore, the proposed bundling device allows many users to tie cylindrical vinyl with only one hand from the first use. In contrast, to make a knot usually requires two free hands. With the waste storage device of the present invention, for example, while holding an infant with one hand, the diaper can be discarded with the other hand and a knot can be formed on the cylindrical vinyl.

  The distance between the axes of the two pin-like parts increases towards the ends of the two pin-like parts, and the angle between the axes measured in the region of the opening of the two pin-like parts is less than 60 ° It is advantageous if there is. That is, the end portions of the two pin-shaped portions are basically directed in the same direction (not opposite directions). By such means, the loop of the cylindrical vinyl is well held by the binding device while the knot is made, and the knot made of the cylindrical vinyl can be easily pulled out of the binding device. The greater the angle, the lower the risk of unintentionally dropping the knot. However, if the angle exceeds 60 °, the knot may become jammed in the binding device.

  Furthermore, it is advantageous if the axes of the two pin-like parts are substantially parallel and the ends of the two pin-like parts are essentially oriented in the same direction (not the opposite direction). In the present specification, “substantially parallel” means that the angle between the axes of two pin-shaped portions is 10 ° or less. That is, the distance between the axes of the two pin-like parts does not substantially increase towards the ends of the two pin-like parts, and the angle between the axes measured in the area of the opening of the two pin-like parts is 10 degrees or less. Thereby, the knot of a cylindrical vinyl can be more easily extracted from a binding apparatus.

  It is also advantageous that the notch has a V shape and extends towards the ends of the two pin-like parts. Thereby, the cylindrical vinyl can be easily passed through the formed loop. However, the cuts may be bounded by parallel walls.

  It is also advantageous if a blade is arranged in the cut. Thereby, a cylindrical vinyl can be cut | disconnected easily. By providing the blade, an integrated binding / cutting device is provided.

  In a further advantageous embodiment, the stopper is arranged at a distance from the free end of the pin-like part. In particular, the stopper is arranged at the end of the notch or before the end of the notch. By such means, it is possible to avoid undesired slipping of the cylindrical vinyl which is passed between the pins and through the loop of the cylindrical vinyl into the portions other than the cut portion of the binding device.

  In yet another advantageous embodiment, the binding device comprises a recess provided on and along the pin-like portion. This allows a person making a knot to easily put his finger, especially the thumb, into a loop formed by a cylindrical vinyl wound around two pins. Therefore, the knot is more easily completed by passing the free end of the tubular vinyl through the loop.

  In a further advantageous embodiment of the waste storage device, one of the pin-like parts is formed by a rack rod guide for the rack rod. In this way, the waste storage device of the present invention has a very compact design because the pin has two functions. In this regard, it is further advantageous if the first pin-shaped part is formed by a rack bar guide and the second pin-shaped part is formed by a fastener.

  In another advantageous embodiment, the waste storage device comprises a holder for receiving an annular storage cassette containing a waste storage bag or tubular vinyl. Therefore, waste can be discarded multiple times without changing the storage cassette.

  Advantageously, a holder is attached to the container. In a preferred embodiment, the storage cassette is simply placed on the holder. The storage cassette may rotate freely to follow the movement of the drive ring or may be fixed to the holder so that it does not rotate with the drive ring.

  In a further advantageous embodiment, the holder is attached to or provided on the drive ring, and the holder and the drive ring rotate together. In a preferred embodiment, the storage cassette is simply placed on the drive ring. In this case, the storage cassette rotates in synchronization with the drive ring. This prevents unwanted twisting of the waste storage bag or cylindrical vinyl in the storage cassette.

  In a further advantageous embodiment, the waste storage device comprises a crank handle in conjunction with a drive ring. This provides an alternative means by which the drive ring can be activated and rotated without direct user touch.

Directions and relative positions (top, bottom, side, etc.) are shown corresponding to the associated drawings, and the indicated directions and / or relative positions need to be corrected in each drawing according to the situation. .

  1-5 illustrate an exemplary waste storage device and waste storage system. 1 is a cross-sectional view of the waste storage device taken along the cutting line AA of FIG. 4, FIG. 2 is a cross-sectional view of the upper portion of the waste storage device, and FIG. 3 is a cross-sectional view of FIG. 4 is a cross-sectional view of the waste storage device in B, FIG. 4 is a perspective view of the waste storage system with the lid opened, and FIG. 5 is a perspective view of the waste storage system with the container opened. FIG. 4 further shows the direction of the cutting plane with respect to FIGS.

  The waste storage device 1 includes a container having a container upper part 2 and a container lower part 3, and the container upper part 2 and the lower part 3 are preferably made of plastic. The container upper part 2 is rotatably connected to the container lower part 3 by the first hinge 4, and the internal space of the container can be accessed by this connection. The container can be easily opened by the handle 5. In normal operation, the button 6 secures the container upper part 2 to the container lower part 3, and the button 6 is locked in the recess 7. The lock may be released by pressing the button 6.

  A container opening 8 that is closed by a lid 9 is provided at the top of the containers 2 and 3. The lid 9 is pivotally attached to the container upper part 2 by a second hinge 10 so that the container opening 8 can be accessed. An optional spring 11 may be provided so that the lid 9 opens automatically.

  The waste storage device 1 further comprises a drive ring 12 rotatably attached to the container in the region of the container opening 8, the drive ring 12 passing through the central opening of the drive ring 12. The bag, that is, the cylindrical vinyl 13 is configured to be locked. In this embodiment, the drive ring 12 is mounted on a support 14 and comprises an optional funnel with an elastic flap / lid 15. Preferably, the waste storage bag or tubular vinyl 13 is made of plastic film and the flap / lid 15 is made of elastomer.

  Further, the waste storage device 1 includes a holder 16 for receiving an annular storage cassette 17 containing a waste storage bag, that is, a tubular vinyl 13. In this embodiment, the storage cassette 17 includes a lower ring 18 and an upper ring 19. Furthermore, in this embodiment, the holder 16 is a part of the container upper part 2, and the storage cassette 17 is simply placed on the holder 16. Therefore, the waste storage cassette 17 can freely rotate. However, the storage cassette 17 may be fixed to the holder 16 (so as not to rotate), and the holder 16 may be attached to the drive ring 12 such that the holder 16 and the drive ring 12 rotate together. May be provided. It can easily be imagined that the storage cassette 17 is placed on the drive ring 12 if the holder 16 is omitted or if it is part of the drive ring 12.

  The waste storage device 1 forms a waste storage system 20 together with the storage cassette 17.

  The drive ring 12 may include teeth as shown. Specifically, an annular gear 21 is mounted on the drive ring 12, that is, the drive ring 12 includes an annular gear 21 that cooperates with a bevel gear 22 that is rotatably attached to a container by a shaft 23. In the present embodiment, the annular gear 21 has teeth on the conical surface and cooperates with the bevel gear 22. The bevel gear 22 is interlocked with a gear 24 that cooperates with the rack bar 25.

  Alternatively, the rack bar 25 may cooperate directly with the annular gear 21. In this case, the rack bar 25 is arranged in the horizontal direction. However, when the container opening 8 is arranged in the vertical direction, the rack bar 25 may be arranged vertically.

  Further alternatively, the crank handle may be associated with the drive ring 12. For example, the shaft 23 can be elongated as shown to extend out of the container. In this case, the crank handle may be attached by the shaft 23 outside the container (left side of the container in FIG. 3).

  The rack bar 25 may be spring biased so that the first end of the rack bar 25 is guided into the containers 2 and 3 by the rack bar guide 26 and moved to the idle position after operation. The rack bar 25 is surrounded by a gear box 27. Further, the container may include a fastener 28 attached to a gear box 27, which is configured to secure a waste storage bag or tubular vinyl 13 (see also FIG. 9). ). An optional blade 29 may be mounted in the area of the rack bar guide 26 or fastener 28. The bevel gear 22 and / or the gear 24 (or optionally another gear of the drive mechanism) may further comprise a one-way clutch device (see also FIGS. 6-8). Further, as shown in FIG. 3, the rack bar 25 may have an optional thick part, that is, a push button 30, at its upper end.

  The functions of the waste storage device 1 and the waste storage system 20 are shown below.

  In the first step, the storage cassette 17 is attached to the holder 16, and the waste storage tubular vinyl 13 is pulled upward and passed through the drive ring 12. The knot 31 closes the end of the waste storage tubular vinyl 13. Here, the waste storage system 20 can be used.

  In the next step, infant or adult diapers, or other personal waste, is thrown into the storage tubular vinyl 13 and discarded. For this reason, the pop-up lid 9 is automatically opened by the spring 11 when the corresponding button at the front of the container is pressed. Next, the rack bar 25 is moved upward by a spring (not shown in FIGS. 1 to 5 but shown in FIG. 6).

  Since the lid 9 is opened when the user presses the button with one hand, for example, the infant can be freely held with the other hand at the same time. However, the spring 11 may be omitted. In that case, the lid 9 is opened by simply lifting.

  When waste is thrown into the rotating funnel, the elastic flap / lid 15 returns to its idle position and closes the waste storage tubular vinyl 13. Here, when the lid 9 is closed, the rack bar 25 is pushed downward. Thus, the lid 9 closes the container opening 8 and cooperates with the rack bar 25. The movement of the rack bar 25 causes the gear 24, the bevel gear 22, and the drive ring 12 to rotate. Thereby, the cylindrical vinyl 13 for waste storage is twisted and closed.

  The return and twisting action of the elastic flap / lid 15 traps the odor in the waste storage tubular vinyl 13. In addition to the automatic operation of the rack bar 25 by the lid 9, if the rack bar 25 is intentionally operated as required, the deodorization function may be further improved. The drive ring 12 is, for example, by pushing a push button 30 on the second end, which is the free end of the rack bar 25, or by turning the crank handle in conjunction with the drive ring 12, if any. Can be operated intentionally. In this regard, it should be noted that the rack bar 25 may cooperate directly with the annular gear 21 and may be arranged horizontally. In this case, the push button 30 may be disposed on the side surface of the container.

  In this embodiment, the drive ring 12 is driven manually, for example, by closing the lid 9 by hand or pressing the push button 30. However, an electric operation is also conceivable. For example, a switch that is activated when the lid 9 is closed and the rack bar 25 is pushed can start a timer and motor associated with the drive ring 12. In this way, the drive ring 12 automatically rotates for a fixed (determined) time.

  In this embodiment, the storage cassette 17 is simply placed on the holder 16 and rotates freely when the drive ring 12 is operated. When the holder is fixed to the drive ring 12, the holder 16 and the storage cassette 17 may move in synchronization with the drive ring 12. However, the storage cassette 17 may be fixed to the holder 16 (so as not to rotate with the drive ring 12).

  Furthermore, in this embodiment, since the one-way clutch device prevents the drive ring 12 from reciprocating, the torsion of the waste storage tubular vinyl 13 generated when the rack bar 25 is pushed releases the rack bar 25. Will not be resolved. Alternatively, however, the elastic flap / lid 15 may be asymmetrically shaped (eg, sawtooth) for the reasons described above. Furthermore, the fastener 28 may be used to improve the twisting function. After throwing away the waste, the container is opened by pressing the button 6 and using the handle 5 to lift the upper part 2 of the container. As a result, the twisted portion of the waste storage tubular vinyl 13 is tightened by the fastener 28 (see FIG. 5).

  In a preferred embodiment, blades 29 are located in the area of fasteners 28 and in the area of rack bar guide 26. In this way, a part of the waste storage tubular vinyl 13 can be cut. In this regard, it should be noted that the use of the waste storage device 1 is not limited to the use of the waste storage tubular vinyl 13. Alternatively, a waste storage bag may be used. In this case, the knot 31 may be omitted. The functions described above apply to waste storage bags as well.

  In the present embodiment, the rack bar 25 is straight / straight. However, this is not a requirement, and the rack bar 25 may be arcuate. Furthermore, the rack bars 25 may be arranged diagonally or horizontally, in contrast to the embodiment shown in the drawings. In this case, the second end portion, which is the free end portion of the rack bar 25, can face the wedge portion of the lid 9, and this wedge portion allows the vertical movement or rotation of the lid 9 to be horizontally applied to the rack rod 25. Convert to move.

  In the illustrated embodiment, the rack bar 25 is disposed near the second hinge 10. Thereby, the moving distance of the rack bar 25 is shortened. However, the rack bar 25 may be disposed opposite the second hinge 10, i.e., more distant from the second hinge 10 than shown, thereby operating the rack bar 25 with less force. Can do.

  In short, in the present invention, the waste storage device 1 and the waste storage system 20 are provided, and the waste storage device 1 and the waste storage system 20 trap the malodor in the waste storage bag, that is, the cylindrical vinyl 13. . The waste storage device 1 is provided with a rack bar 25, and the rack bar 25 is guided and driven to move into the containers 2 and 3 at the first end of the rack bar 25 (here, at its lower end). Interlocks with the ring 17. Further, the rack bar 25 faces the lid 9 at the second end which is the free end of the rack bar 25 (here, at the upper end thereof) and cooperates with the lid 9. The waste storage device 1 provides an automatic operation when the lid 9 is opened and closed, but is intended on demand by a push button 30 on the second end, which is the free end of the rack bar 25. Can also be operated manually.

  Here, FIG. 6 shows an exploded view of the rack bar mechanism and the drive unit of the waste storage device 1. Specifically, FIG. 6 shows two parts 27a and 27b of the gear box 27, a bevel gear 22, a shaft 23, a gear 24, a one-way clutch device 32, a rack bar 25 having a thick part / push button 30, and a rack. A bar spring 33 is shown. As described above, when the rack bar 25 is pushed, the gear 24 rotates. When the rack bar 25 moves downward, the one-way clutch device 32 having a ratchet mechanism or using friction is caught, and the gear 24 and the bevel gear 22 rotate together / synchronously. The bevel gear 22 projects through the recess 24 and engages with the drive ring 12 (not shown in FIG. 6), whereby the drive ring 12 rotates.

  When the rack bar 25 is released, the rack bar 25 is moved upward to the idle position by the rack bar spring 33. Since the one-way clutch device 32 is not caught when the rack bar 25 moves upward, the bevel gear 22 remains stationary while the gear 24 is rotated by the moving rack bar 25.

  In this embodiment, the one-way clutch device 32 is caught when the rack bar 25 moves downward, and is released when the rack bar 25 moves upward. This is an advantageous variant, but is not a requirement. The one-way clutch device 32 may be caught when the rack bar 25 moves upward, and may be released when the rack bar 25 moves downward. In this case, the bevel gear 22 and the drive ring 12 are driven by the rack bar spring 33.

  7 and 8 exemplarily show a drive unit for the waste storage device 1 similar to the drive unit shown in FIG. In contrast, the one-way clutch device 32 incorporates a one-way clutch device that utilizes friction. FIG. 7 is a detailed side sectional view of the drive unit, and FIG. 8 is a front sectional view of a one-way clutch device using friction. It should be noted that the one-way clutch device of FIGS. 7 and 8 is partly formed by a bevel gear 22 and a gear 24, does not have a dedicated housing, and is not an independent device.

  Specifically, the one-way clutch device includes a roller 35, and the roller 35 is disposed between a gear 24 that forms an inner driven shaft and a bevel gear 22 that forms an outer sleeve. The roller 35 is disposed in the wedge-shaped or tapered cut-out portion 36 of the gear 24, and the inner peripheral surface of the bevel gear 22 prevents the roller 35 from coming off the cut-out portion 36. The roller 35 is spring-biased by a roller spring 37. An optional pressing plate 38 may be used to transmit the spring force to the roller 35.

  When the bevel gear 22 rotates counterclockwise, the roller 35 is caught by the bevel gear 22 in a tapered space between the notch 36 and the inner peripheral surface of the bevel gear 22, and the gear 24 and the bevel gear 22 together. Rotate. When the gear 24 rotates clockwise, the roller 35 simply slides on the inner peripheral surface of the bevel gear 22. In this case, even if the gear 24 rotates, the bevel gear 22 is stationary.

  A special advantage of one-way clutch devices that utilize friction is that they operate very quietly and are almost inaudible. In this way, the user of the waste storage device 1 and the infant (sleeping) are not bothered by the sound of the waste storage device 1.

  In the embodiment shown in FIGS. 6 to 8, the one-way clutch device 32 is disposed between the gear 24 and the bevel gear 22. This is an advantageous method, but is not a requirement, and the one-way clutch device 32 may be arranged at another position of the drive of the waste storage device 1.

  FIG. 9 is a perspective view of an exemplary binding / cutting device 39 as viewed from above. The binding / cutting device 39 includes two pin-like portions 40 and 41 with a cut portion 42 provided therebetween. Thereby, the knot 31 can be easily made in the cylindrical vinyl 13. The cylindrical vinyl 13 is wound around two pin-like portions 40 and 41, and is passed through the loop of the formed cylindrical vinyl 13 via the pin-like portions 40 and 41 (see FIG. 9). The final downward movement not only completes the knot 31, but also allows the completed knot 31 to be removed from the binding / cutting device 39.

  The above-described operation can be easily performed with one hand. In contrast, making a knot 31 usually requires two free hands. With this waste storage device 1, for example, while holding an infant with one hand, a used diaper can be discarded with the other hand to make a knot 31 on the tubular vinyl 13. Of course, the travel path starting from the left side shown in FIG. 9 is merely exemplary, and the movement may be initiated from the front side, the left side, the right side, the back side, or other directions therebetween.

  Note that the binding / cutting device 39 of FIG. 9 is incorporated as a separate device. The bundling / cutting device 39 may be attached to the body of the waste storage device 1 using a snap-type connection or a friction connection if it is removable. The waste storage device 1 may optionally comprise a plurality of attachment positions, i.e. receiving positions, for attaching the binding / cutting device 39 arbitrarily, in particular detachably. A plurality of binding / cutting devices 39 may be mounted at the mounting / receiving position. For example, two binding / cutting devices 39 may be mounted in two of the three mounting / receiving positions.

  However, the binding / cutting device 39 may be permanently attached to the body of the waste storage device 1 using, for example, an adhesive or by welding. Of course, the binding / cutting device 39 may be part of the waste storage device 1.

  In this regard, it is particularly advantageous if one of the pin-like parts 40, 41 is formed by the rack bar guide 26. That is, the rack bar guide 26 and the fastener 28 shown in FIGS. 1 to 7 form the pin-like portions 40 and 41 of the binding / cutting device 39 shown in FIG. Further, the rack bar guide 26 and the fastener 28 may be formed not only for sandwiching the cylindrical vinyl 13 as shown in FIG. 5 but also for making a knot 31 in the cylindrical vinyl 13. By integrating the rack bar guide 26 and the binding / cutting device 39 (i.e., the binding / cutting devices 26, 28), the waste storage device 1 can be designed to be very compact. The technical teaching described above with respect to the binding / cutting device 39 shown in FIG. 9 is equally relevant to the binding / cutting devices 26, 28 shown in FIGS. Accordingly, when only one is used instead for the sake of simplification of the present specification, the “binding / cutting device 39” may be changed to the “binding / cutting device 26, 28”. 26, 28 "may be changed to" Bundling / cutting device 39 ". It should be noted that the rack bar guide 26 may be a single part and may be composed of a plurality of rack bar guides 26a, 26b as shown in FIGS.

  In the embodiment shown in FIG. 9, the bundling / cutting device 39 includes a blade 29 disposed in the cut portion 42. Thereby, the cylindrical vinyl 13 can be cut | disconnected easily. Note that the blade 29 is optional. If the blade 29 is not provided, the device 39 shown in FIG. 9 is merely a bundling device. Of course, the waste storage device 1 may include a plurality of single binding devices and cutting devices that provide a binding function and a cutting function.

  In the embodiment shown in FIG. 9, the axes of the two pin-like portions 40 and 41 are substantially parallel, and the ends of the two pin-like portions 40 and 41 are basically in the same direction (not opposite directions). Facing. In FIG. 9, both ends are directed downward (not downward and upward). In the present specification, “substantially parallel” means that the angle α between the axes of the two pin-like portions 40 and 41 is 10 ° or less. For this reason, the loop for making the knot 31 is well held by the binding / cutting device 39 while the knot 31 is being made, and the knot 31 of the tubular vinyl 13 is very easily removed from the binding / cutting device 39. Can be removed. However, the angle between the axes of the two pin-like portions 40, 41 may be up to 60 ° (the right side of FIG. 9 schematically depicting the “direction” of the two pin-like portions 40, 41). checking). In this case, the loop of the tubular vinyl 13 is better held by the binding / cutting device 39 while the knot 31 is being made. The greater the angle, the lower the risk that the knot 31 will unintentionally fall out of the binding / cutting device 39. However, if the angle exceeds 60 °, the knot 31 may become jammed in the binding / cutting device 39.

  In this embodiment, the cut portion 42 is bounded by parallel walls. However, the cut portion 42 may have a V shape and may extend toward the ends of the two pin-like portions 40 and 41. Thereby, the cylindrical vinyl 13 can be more easily passed through the loop.

  The binding / cutting device 39 may also include an optional stopper 43 disposed at a distance from the free ends of the pin-like portions 40, 41. In particular, the stopper 43 is arranged at the end of the cut portion 42 or before the end of the cut portion 42. By these means, when the cylindrical vinyl 13 is wound around the pin-shaped portions 40 and 41, particularly when moved upward, the cylindrical vinyl 13 to a portion other than the cutting portion 42 of the binding / cutting device 39 is used. Undesirable slippage can be avoided. When such an undesirable slip occurs, the cylindrical vinyl 13 that is passed through the loop from between the pin-like portions 40 and 41 is prevented from moving. As a matter of course, the stopper 43 may be disposed on both the pin-like portions 40 and 41.

  In the embodiment shown in FIG. 9, the binding / cutting device 39 comprises a recess 44 that extends along the pin-like portions 40, 41. By this means, the user who makes the knot 31 can easily put his finger, in particular the thumb, into the loop formed by the tubular vinyl 13 wound around the two pin-like portions 40, 41. Therefore, the knot 31 is more easily completed by passing the free end of the tubular vinyl 13 through the loop.

  It should be noted that the present invention is not limited to the above-described embodiments, and combinations of different embodiments are possible. Indeed, the waste storage device 1 and the waste storage system 20 may have more or fewer parts than shown. The waste storage device 1, the waste storage system 20, and their components may be shown on different scales and may be enlarged or reduced from the scale shown. Finally, this specification may further include the technical contents of the independent invention.
