Description

  The present invention relates to a portable toilet that can be transported, and more particularly to a portable toilet in which a toilet seat is provided with a cleaning device.

  A chair-type portable toilet that is used by elderly people and people with disabilities in their rooms and hospital rooms is known, but in recent years, portable toilets with a cleaning device for cleaning the buttocks in the toilet seat have become widespread. ing. For example, see Patent Document 1.

  In a cleaning device that cleans the buttocks, the nozzle is generally cleaned while the nozzle is retracted. In the portable toilet, the cleaning water is trapped in a bucket placed on a chair. Since it is necessary, the bucket is generally positioned so as to overlap the lower part of the nozzle so that the washing water can be reliably trapped. Therefore, when removing the bucket, simply lifting the bucket vertically, the bucket rear end and nozzle, and a guide plate for guiding cleaning water to the bucket below the nozzle are unavoidable. There was a problem that the rear end of the interference.

  For this measure, in Patent Document 1, the bucket is not placed directly on the chair but is placed on a drawer-type load receiving member that slides in the front-rear direction. Thus, when throwing away the excrement, the bucket is first slid to the front position where the overlap can be eliminated through the load receiving member, and the bucket is pulled up in the vertical direction in this state, so that the bucket is guided to the guide plate. It is devised so that it can be taken out without interfering with.

JP 2006-94901 A

  In the structure of Patent Document 1 configured as described above, the bucket can be taken out without interfering with the guide plate, but the removal method cannot be performed by one operation of lifting the bucket. In addition to the problem that inconvenience remains by all means, the structure of Patent Document 1 is indispensable for the needs that are indispensable for portable toilets that need to be transported according to the location of the user when not using it. Work is particularly difficult when elderly people or people with physical disabilities transport this portable toilet because it requires rails as well as pull-out load-bearing members, which are inevitably heavy. There was a problem that would force you.

  In addition, if the load receiving member is not stored securely, the bucket will not be in the proper stored state, so the cleaning water for nozzle cleaning will not be trapped in the bucket, and the excrement will be trapped securely. There were also problems such as being unable to do so, and excessive water splashing in the bucket due to the fall of excrement.

  In addition, portable toilets are transported on a daily basis, but even if the bucket is placed in a normal storage state, the bucket will deviate from the normal state due to vibrations associated with the transport, etc. There was also a problem that the above problem would occur due to the added use.

In order to solve the above problems, a chair member on which a user is seated, a bucket serving as a container for excrement that is detachably placed on the seat surface of the chair member, and a rear end of the chair member being swingable In a portable toilet provided with a toilet seat pivotally attached and capable of taking a standing position and a horizontal position covering the upper surface of the bucket,
A cleaning device provided with a nozzle provided on the rear side which is the back side of the user when the toilet seat is seated;
A guide plate that is located below the nozzle in a retracted state and guides cleaning water sprayed from the nozzle into the bucket;
The bucket is located below the guide plate and is placed on the chair member so as to overlap the guide plate,
The bucket is slidably mounted on the chair member so that a first position overlapping the guide plate and a second position sliding forward from the first position can be taken. A handle that can take a substantially horizontal storage state on the front side of the chair member is pivotally attached to the bucket so as to be swingable. By setting the handle to the storage state, a second position of the bucket with respect to the chair member And the position of the bucket is restricted to the first position.

  Since it is configured as described above, when throwing away the excrement in the bucket, the bucket slides forward simply by pulling out the handle provided on the front side of the bucket, and the handle is in a vertical state. In this state, the interference between the rear end of the bucket and the guide plate is also avoided, so that the bucket can be reliably and easily taken out with one take-out operation.

  Further, when the bucket is stored, the handle is configured so that the handle cannot be placed in the horizontal normal storage state unless the bucket is in the normal first position, so that the bucket can be surely recognized that the bucket is not in the normal position. Become.

  Furthermore, since the bucket is stored in the normal first position and the handle is placed in the horizontal normal storage state, the bucket is prevented from sliding from the first position to the second position. In addition, it is possible to prevent the problem that the bucket is displaced from the normal position due to vibrations or the like accompanying the conveyance of the portable toilet. Furthermore, since it can be performed without the troublesome task of simply storing the handle, it has a very practical effect in the field of portable toilets where the elderly and persons with physical disabilities can work.

  Further, since the bucket is configured to slide, the binding force of the bucket to the chair member is weakened in the retracted state of the bucket, so that the bucket support rigidity is low, and therefore the noise increases when the bucket is used. However, it is possible to solve the problem of noise, which is a very big problem in portable toilets that can reduce the noise by increasing the support rigidity of the bucket because the holding force is restrained so as to regulate the slide by storing the handle Is.

  In the portable toilet according to claim 2, the chair member is formed with a step-like storage portion that is stepped downward so that the handle is stored substantially horizontally in the storage state, and the handle includes the handle, The bucket is configured to regulate sliding of the bucket by abutting against the vertical surface of the storage portion.

  In the present invention, the seat surface of the chair member is formed in a staircase shape to form a storage portion, whereby the handle and the bucket can be stored substantially horizontally. Further, since the handle is supported by the vertical surface of the storage portion and thereby the slide of the bucket is restricted, the storage of the handle and the slide of the bucket can be restricted with an extremely simple configuration.

  According to a third aspect of the present invention, the handle is configured to be supported via a fitting mechanism so that the vertical movement of the storage portion is restricted.

  As a result, the handle is securely retracted by the action of the fitting mechanism, so that the sliding of the bucket can be regulated more reliably and firmly. In addition, it is possible to reliably recognize that the bucket is stored at a regular position based on the fitting feeling, and it is possible to suppress human errors.

  Furthermore, since the fitting mechanism gives a restraining force to the storage of the handle, the support rigidity of the bucket is further increased and the noise can be greatly reduced.

  5. The portable toilet according to claim 4, wherein the toilet seat is placed in a horizontal position to cover the handle, thereby restricting the storage of the handle in the storage portion, thereby moving the bucket from the first position to the second position. Are configured to be regulated.

  As a result, the handle can be prevented from jumping out of the storage portion in the toilet seat, so that it is possible to reliably control the slide even if there is vibration during the transportation of the bucket.

The portable toilet according to claim 5, wherein the toilet seat is configured to be seated on the upper end surface of the bucket by setting the toilet seat at a horizontal position at least at the first position of the bucket, and the bucket is pressed by the seat of the toilet seat. The movement of the bucket is restricted.

  As a result, the load of the toilet seat acts on the bucket, so that the slide is reliably regulated even if there is vibration during the transportation of the bucket. In addition, when a load is added, a human load acts on the bucket. Even in the present structure in which the bucket support rigidity is further increased and the slide mechanism is provided to the bucket, an extremely high support rigidity can be provided, so that an effect of being able to reliably reduce noise during urination or the like is achieved.

The portable toilet according to claim 6, wherein the bucket is stored so that an upper end surface of the bucket protrudes from an upper surface of the chair member at least in the first position, and the toilet seat is in the horizontal position. The seat is configured to be seated on the upper end surface of the bucket, and the bucket is pressed by the seating of the toilet seat to restrict the movement of the bucket.

  Thereby, since the upper end surface of the bucket is configured to protrude from the seat surface serving as the upper end surface of the chair member, it is possible to reliably bring the bucket into contact with the toilet seat. The supporting rigidity of the bucket can be increased. Furthermore, since the part protruded from the seat surface covers the gap between the toilet seat and the bucket, sound insulation during urination can be performed in addition to the above-described effects.

The portable toilet according to claim 7 is configured such that when the bucket is in the second position, the handle abuts against a peripheral edge of the storage portion so that the handle is not stored in the storage portion, and the handle is Inclining angle expanding means for increasing the inclination angle of the handle in the unstored state of the handle is formed on the peripheral edge in contact with the peripheral edge or on the handle portion in contact with the peripheral edge.

  As a result, when the bucket is not stored in the proper first position, the handle is brought into contact with the peripheral edge of the seating surface, and the handle is inclined greatly by the action of the inclination angle expanding means. Therefore, the user can easily determine that the bucket is not in a normal position, and can prevent the bucket from being used accidentally in a bad storage state of the bucket.

The portable toilet according to claim 8, wherein the inclination angle expanding means is an upward convex portion provided on a peripheral edge of the storage portion or a downward convex portion formed on a handle portion in contact with the peripheral edge.

  Thus, a simple configuration can be achieved.

  According to the portable toilet according to the present invention, the bucket can be easily taken out without making the portable toilet heavy, and reliably avoiding interference with the nozzle and the guide plate of the cleaning device, and easily and surely in a normal position. In the field of portable toilets that can be stored and held, it is possible to achieve extremely unique effects.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a portable toilet equipped with a cleaning device according to the present invention. On a seat surface 1a of a wooden chair member 1, a cleaning device 2 for cleaning the hips is fixed at the rear end. In addition, the toilet seat 4 is supported to be swingable with respect to the front surface of the cleaning device 2 through a hinge 3 so that the toilet seat 4 can take two positions, a horizontal position shown in FIG. Yes.

  In the figure, reference numeral 5 denotes a cushioning seat for a user to sit when using the portable toilet as a chair. The seat 5 covers the upper surface of the toilet seat 4 and is a horizontal position where the toilet seat 4 is seated. As shown in the figure, the seat part is erected in a folded state through the support member 5a, so that when it is used, the seat part 1 comes into contact with the back part 1b of the chair member 1 so as to function as a cushioned backrest. It is configured.

  In the figure, 2a is an operation panel for selecting the function of the cleaning device 2, and 1e and 1f are armrests. As can be seen from the figure, the armrest 1f on one side is configured to be short, and this is because a person with a physical disability supports the body from the short armrest 1f side to the armrest 1f while shortening it to the portable toilet. Is designed so that it can be easily slid.

  Next, a description will be given focusing on the inside of the opening 4a opened in the center of the toilet seat 4. A seat opening 1d for the bucket 6 larger than the opening 4a is formed on the seat surface 1a of the chair member 1 below the toilet seat 4 while corresponding to the opening 4a. On the periphery of the storage opening 1d, there is formed a step-like storage portion 1c that supports a bucket 6 (to be described later) and is stepped down to store a handle 9, and the flange of the bucket 6 is provided in the storage portion 1c. The bucket 6 is supported by the chair member 1 by placing 6a. Further, the handle 9 is also placed on the storage portion 1c, and the horizontal storage state is maintained by being placed. Moreover, the handle 9 is comprised so that it may contact | abut to the vertical surface 1h of a staircase-shaped storage part in the storage state.

  In the figure, reference numeral 7 denotes a lid that covers the opening of the bucket 6, and this lid 7 plays a role of preventing odors and splashing of accumulated water when the bucket 6 is transported.

  Next, a nozzle 2b for cleaning the butt is provided on the opening 4a side of the cleaning device 2 so as to be able to take a retracted state and an extended state as shown in the figure. Below the nozzle 2b is a chair member. A guide plate 8 fixed to one seating surface 1a is provided. The guide plate 8 is provided below the nozzle 2b so that the cleaning water sprayed by the nozzle 2b for cleaning the nozzle 2b is surely guided into the bucket 6. Here, supplementing the cleaning of the nozzle 2b, in order to clean the nozzle 2b when the nozzle 2b is in the retracted state of the figure, the nozzle is directed from the nozzle 2b toward the upper wall of the cleaning chamber 2c located above the nozzle 2b. The nozzle 2b is sprayed with cleaning water by itself, and the nozzle 2b is cleaned with the rebounding cleaning water. The cleaning water that has cleaned the nozzle 2b falls on the upper surface of the guide plate 8, and the guide plate 8 It is transmitted and falls into the bucket 6.

  2 is a perspective view similar to FIG. 1, except that the cleaning device 2, the toilet seat 4 and the seat portion 5 are removed so that the seat surface 1a and the bucket 6 of the chair member 1 can be easily confirmed. The same applies to the following, but the same components as those in FIG.

  In FIG. 2, since the toilet seat 4 is removed, a substantially U-shaped handle 9 for taking out and transporting the bucket 6 to a position corresponding to the front lower portion of the toilet seat 4 is stored on the front side of the bucket 6. It can be seen that the handle 9 is swingably attached to the bucket 6 so as to straddle the side upper part of the bucket 6. In addition, the state of the handle 9 shown in the drawing is a normal storage state stored in the storage unit 1c and horizontal.

  Next, in the normal storage state of the bucket 6 shown in the figure, the gap 10 is continuously provided from the center of the bucket 6 to the entire circumference around the front side. This means that the bucket storage opening 1d formed on the seating surface 1a is longer than the longitudinal length of the bucket 6 in the longitudinal direction, whereby the bucket 6 is within the storage opening 1d. It is configured to slide in the front-rear direction. Needless to say, the flange 6a of the bucket 6 is slidably mounted on the storage portion 1c so as to ensure this sliding.

Here, one of the ideas of the present invention will be described. Although the bucket 6 can be slid by setting the gap 10 as described above, the handle 9 is stored in the storage portion 1c, and the slide of the bucket 6 is brought into contact with the vertical surface 1h. Is configured to be regulated.
As a result, it is possible to reliably prevent a problem that the bucket slides due to the vibration at the time of transporting the portable toilet accompanying the cleaning of the room, the changing of the room, the movement of the user, and the like. Therefore, it is possible to use the device with peace of mind without confirming whether the position of the bucket is in a normal storage state during use. Note that the handle 9 may only abut against the vertical surface 1h. However, in the present invention, the vertical surface 1h is formed in a concave shape so that the round cross section of the handle 9 is fitted therein by using the elastic force of the handle 9. Thus, the support rigidity of the bucket 6 is increased, and the removal of the handle 9 is reliably suppressed.

  Next, the reason why the bucket 6 is allowed to slide will be described with reference to FIG. FIG. 3 is a side view using a partial cross-sectional view. As is apparent from this figure, the bucket 6 can reliably trap the cleaning water for cleaning the nozzle 2b described above in a normal storage state. Thus, the guide plate 8 and the rear end of the bucket 6 are arranged so as to overlap each other by a length L below the guide plate 8 described above. As a result, the cleaning water for cleaning the nozzle 2 b falling on the guide plate 8 can be surely dropped into the bucket 6. Therefore, the rear end (left side in the figure) of the bucket 6 is configured in such a way that the rear end is largely cut by the recess 6b so as to overlap the guide plate 8 as clearly shown in FIG.

  Next, in the present invention, in order to facilitate the removal of the bucket 6, the handle 9 is disposed in the retracted state so as to be positioned on the front side as shown in the figure. I will explain the point of view.

  In general, a gap L1 exists between the upper surface of the bucket 6 and the lower side of the toilet seat 4, but in the present invention, the gap L1 is integrally extended from the flange 6a of the bucket so as to be integrally formed by the shielding portion 6c. It is configured to shield. This prevents small water or accumulated water in the bucket 6 from splashing from the gap L1 and adhering to the grip portion 9b of the handle 9. By this shielding part 6c, the bucket 6 can be taken out cleanly, and uncomfortable feelings such as caregivers can be eliminated.

  Further, when the toilet seat 4 is set to the horizontal position shown in the drawing, the shielding portion 6c is configured to be in close contact with the lower surface of the toilet seat 4 so that the toilet seat 4 is pressed into FIG. As can be seen from the perspective view of the bucket 6 shown in the figure, the shielding portion 6c is long except for the rear end portion. It works effectively against the problem of sound during use that has been a burden on the user, reduces sound leakage, and does not have much anxiety or discomfort even in a usage environment that is not a toilet booth It is also possible to produce an excellent effect that it can be added.

Further, since the lower surface of the toilet seat 4 is configured to directly contact the shielding member 6c of the bucket 6, the sliding of the bucket 6 can be reliably regulated by the load of the toilet seat 4 by placing the toilet seat 4 in a horizontal position. is there. Further, in the present invention, not only the shielding member 6c abuts on the lower surface of the toilet seat 4, but also the deformable feet made of rubber or the like (not shown) provided on the lower surface of the toilet seat are arranged outward from the shielding member 6c. In the position over the flange 6a of the bucket 6 and the seat surface 1a of the chair member 1 stored in the staircase-shaped storage portion 1c on the side, the foot 6 itself is crushed so that the flange 6a in the storage portion 1c Therefore, the excessive deformation of the shielding member 6c can be suppressed, and the sliding of the bucket 6 can be surely prevented.
In the present invention, the foot provided on the lower surface of the toilet seat is in contact with the flange 6a of the bucket. However, the present invention is not limited to this, and the structure in contact with the handle 9 or both the handle 9 and the flange 6a. Needless to say, the toilet seat 4 may be configured such that the weight of the toilet seat 4 acts on the bucket 6 and the slide is suppressed by vibration during conveyance. Further, the toilet seat 4 prevents the handle 9 from jumping out of the storage portion 1c.

  Next, a method for taking out and storing the bucket 6 will be described in detail with reference to FIG. First, the case where the bucket 6 is taken out after use is described. In order to take out the bucket 6 after adding, as shown in FIG. 4a, first, the toilet seat 4 is swung in an upright state, and then the grip 9b of the exposed handle 9 is taken out from the storage 1c and lifted up. The bucket 6 can be easily lifted by pulling the handle 9 while pulling in the A direction, that is, the natural direction of the user, and the A direction (the left side in the figure) when the bucket flange 6a slides inside the storage portion 1c. ), The overlap with the guide plate 8 interferes and the bucket 6 can be taken out upward.

  Here, the viewpoint to which the present invention is further devised will be described. That is, when the bucket 6 is slid in the direction A, the bucket 6 has a certain weight because it contains excrement in addition to the pooled water, but in the present invention, the chair member 1 is slid so that it can be easily slid. By integrally forming a plurality of protrusions 6d on the lower surface of the flange 6a of the bucket 6 that abuts on the storage portion 1c, the contact area is reduced and the sliding resistance is reduced, thereby resisting the weight of the portable toilet. Only the bucket 6 is easily slid to the user side. Here, the bucket 6 is provided with the protrusion 6d, but the protrusion may be formed on the side of the storage portion 1c of the chair member 1, and is not limited to the protrusion, but a low friction tape or a low friction resin member. Needless to say, it is sufficient to apply a low-friction process such as using a roller or using a roller.

  In the state where the bucket 6 has moved forward, the rear end of the bucket 6 can be taken out without interfering with the guide plate 8 by lifting it up through the handle 9 without needing to introduce it as FIG. 4b. Is.

  Next, the procedure for storing the bucket 6 in the portable toilet will be described. The bucket 6 is stored in such a manner that after the bucket 6 that becomes heavier when the reservoir water is contained is placed on the chair member 1 and the like, the bucket 6 is moved backward in a direction away from yourself, which is a direction in which force is difficult to enter. Become work. Thereby, both can be overlapped in the retracted state while avoiding interference between the guide plate 8 and the rear end of the bucket 6.

  The operation for storing the bucket 6 will be described below with reference to FIG. 4c. While the toilet seat 4 is raised, the bucket 6 is inserted into the storage opening 1 d of the chair member 1, and the bucket 6 is placed on the chair member 1 by placing the flange 6 a of the bucket 6 in the storage portion 1 c. At this point in time, the guide plate 8 and the recess 6b of the bucket 6 do not overlap or are slightly overlapped if they are stored rearward with some consideration. In this state, since the bucket 6 is not in a completely retracted state, it is naturally not preferable to clean and use the nozzle 2a in this state.

  Therefore, in the present invention, when the bucket 6 is not in the normal storage state and the handle 9 does not fit in the storage portion 1c, the handle 9 abuts on the periphery of the storage portion 1c in the Z portion on both sides of FIG. One contrivance is that the handle 9 is not in a normal horizontal storage state. As a result, the handle 9 is in an upright state, so that the bucket 6 can be immediately determined visually by the fact that the bucket 6 is in a non-normal storage state, and the toilet seat 4 is not in a normal horizontal position, so It can be easily judged that there is not. Therefore, it is possible to reliably prevent the bucket 6 from being used in an abnormal storage state.

  Furthermore, in this embodiment, if it is found that the bucket 6 is in an abnormal state, the user can again move the bucket 9 while holding the handle 9 again, but this operation is difficult. A person with weak force can easily slide the bucket 6 by pushing the tilted handle 9 backward. In this case, the bucket 6 is lifted or the heavy bucket 6 is moved away from the body. Therefore, the bucket 6 can be placed in a normal storage state very easily, and the guide plate 8 and the bucket 6 can be reliably overlapped.

  Further, in the present invention, a delicate device is applied, and when the bucket 6 as shown in the figure is not in a normal storage state, the toilet seat 4 is pressed from above so that the toilet seat 4 is in a normal position. Alternatively, simply by sitting on the toilet seat 4 to add work, the contact portion 4a provided on the toilet seat 4 presses the handle 9 downward while contacting the handle 9. As a result, the handle 9 receives a downward force, and the curved curved surface portion 9c formed on the handle 9 comes into contact with the inclined surface 1g formed on the storage portion 1c of the chair member 1, and guides the inclined surface 1g. As a result, the bucket 6 moves to the right side of the drawing, which is the rear side, and the bucket 6 automatically slides to a proper position where the guide plate 8 and the rear end of the bucket 6 are surely overlapped. As is clear from the above, the bucket can be stored without worrying about the painful and cumbersome work of overlapping the guide plate 8 and the bucket 6.

  Furthermore, in the present invention, in order to reduce the weight of the sliding operation of the heavy bucket 6, the invention is devised to reduce the frictional force generated between the bucket 6 and the storage portion 1 c, thereby reducing the operating force. However, if the handle 9 is deformed, a sufficient sliding force cannot be secured, but it is not necessary to increase the strength of the handle 9 by reducing the frictional force. The effect that it is not necessary to make it heavy can be produced. Specifically, a plurality of protrusions 6d are provided on the lower surface of the flange 6a of the bucket 6 to make point contact with the storage portion 1c.

  In the embodiment shown in FIG. 4 (c), the handle 9 is provided with a curved surface portion 9c, and an inclined surface 1g is formed on the storage portion 1c so that the bucket 6 can be slid to a normal position. The handle 9 is formed linearly without providing the curved surface portion 9c, and the handle 9 is not provided with the inclined surface 1g, and the handle 9 has a peripheral edge of the storage portion 1c, that is, the upper end of the vertical surface 1h. Needless to say, the handle 9 may be configured to be inclined by coming into contact with.

6 (a) and 6 (b) do not have a function of sliding the bucket 6 backward, but when the bucket 6 is not in a normal storage state, the handle 9 is greatly enlarged and inclined. This is an example in which the user is informed that there is no regular position at a glance.
FIG. 6A shows an embodiment in which the handle 9 is provided with a curved surface portion 9c so as to contact the seat surface 1a of the Z portion in FIG. What is different from FIG. 4C is that the inclined surface 1g is not formed in the storage portion and that the shape of the curved surface portion 9c is formed at an acute angle because it does not aim to slide the bucket 6. .
In the embodiment of FIG. 6B, a spacer 20 is provided separately on the seating surface 1a of the Z portion in FIG. 2, and the handle 9 abuts on the spacer 20 as shown in the figure. Is greatly enlarged and inclined. The spacer 20 may be integrated with the seating surface, or may be a separate member as in this embodiment, and the material may be formed of an elastic material or a resin material and attached. is there.

  Finally, details of the bucket 6 will be described with reference to FIG. The contents described in the previous description are given the same reference numerals and are omitted. This bucket 6 is a silencing bucket, and as shown in FIG. 5b, a convex portion 6e is formed at a portion where small water abuts. The convex portion 6e suppresses vibration by increasing the rigidity of the convex portion. In the present invention, the shape of the convex portion 6e is optimized in detail.

  Specifically, if the convex portion 6e is simply formed in a convex shape, the surface strength cannot be increased unless the convex portion is protruded to a large convex shape, so that the generation of sound cannot be reduced. There is a problem in that a large amount of falling sound is generated because the water is diverted by the convex portion and falls into the accumulated water. In the present invention, first, the first shelf 6f is formed, and the second projection 6g is formed in the center of the shelf 6f so that the upper portion is triangular and widens downward. Configured. By configuring in this way, the surface rigidity can be increased without raising the convex portion 6e so much, so that the impact sound due to the collision of small water and the small water are divided into two at the top of the convex portion. The concentrated sound does not fall in the bucket 6, and the falling sound is greatly reduced because the film 6 is dispersed in the accumulated water and dropped in such a manner that the film is applied to the convex portion 6e.

  In the figure, 6h is a draining groove formed in a concave shape on the upper surface of the flange 6a so as to substantially correspond to the grip portion 9b of the handle 9. Although the shielding member 6c is provided, if the seating state of the toilet seat 4 is inadequate, it is undeniable that small water or the like drips on the grip portion 9b side even if it gets over the shielding member 6c. . The draining groove 9h is accumulated in advance in the draining groove 9h so that the small water does not touch the grip portion 9b even if there is small water dripping over the shielding member 6c. Is. Thus, even in the present case in which the grip portion 9b is securely stored on the front side, the user can carry the bucket 6 by gripping the grip portion 9b without causing concern about dirt.
