Description

Portable toilet bowl and portable toilet

Technical Field

The present invention relates to a portable toilet bowl detachably attached to a toilet body of a portable toilet, and a portable toilet provided with the same.

Background

The portable toilet is provided with a detachable bowl arranged below the toilet seat. After the portable toilet is used, a user or a caretaker (hereinafter, collectively referred to as a user) removes the bowl from the bowl body and conveys the bowl to a sewage discharge place such as a toilet. Then, the user discharges the sewage stored in the tub to a toilet bowl or the like of the toilet.

The barrel has: a container and a handle arranged on the upper part of the container. The user can detach the tub by lifting the handle. In addition, the user can hold the handle to move and carry the barrel. When the portable toilet is used, the handle is put down so as to be out of the way. Thus, the handle is rotatably assembled to the container.

However, if the handle is rotatable, when the user holds the handle to carry the tub, the container may shake and the sewage may splash to the outside. In addition, when the container hits furniture or the like during transportation, the container may incline to spill sewage.

Accordingly, the present inventors considered to provide a mechanism (hereinafter referred to as a locking mechanism) for a portable toilet bowl, which is fixed so as not to rotate relative to the container when the handle is lifted. For example, patent document 1 discloses a bucket which is not used for a portable toilet, but which is provided with such a locking mechanism.

As shown in fig. 32 (a), the lock mechanism disclosed in patent document 1 is constituted by a shaft hole 501 formed in a container 500 and a shaft 511 provided in a handle 510. The shaft hole 501 is formed in an eggplant shape and is composed of a circular hole 502 and a vertical hole 503 above the circular hole 502. The shaft 511 of the grip 510 is formed in a quadrangular transverse sectional shape. As shown in fig. 32 (a), in a state where the handle 510 is laid down, the shaft 511 is located inside the circular hole 502, and thus the handle 510 can be rotated. On the other hand, as shown in fig. 32 (b), if the handle 510 is raised and lifted, the shaft 511 moves from the circular hole 502 to the vertical hole 503, and thus cannot be rotated. Thus, the handle 510 can be fixed in a non-rotatable manner with respect to the container 500.

First, the technical problem to be solved

When discharging sewage from the bowl to the toilet bowl, a user first holds the handle 510 and places the container 500 above the toilet bowl 520 as shown in fig. 33 (a). At this time, as shown in fig. 33 (b), the shaft 511 of the handle 510 is fitted into the vertical hole 503, and the handle 510 is restricted from rotating. Next, as shown in fig. 34 (a), the user holds the handle 510 and pours the container 500. In the case of the tub having the locking mechanism, since the handle 510 is fixed to the container 500 in a non-rotatable manner, the user tilts the handle 510 together with the container 500. At this time, a force tilting from the vertical hole 503 acts on the shaft 511 of the handle 510 (see fig. 34 b). The shaft 511 is gradually inclined and slides from the longitudinal hole 503 toward the circular hole 502. When the degree of inclination increases, the shaft 511 is disengaged from the vertical hole 503 (see fig. 35 (b)). When the shaft 511 is removed from the vertical hole 503, the fastening of the handle 510 is released, and the container 500 is abruptly tilted (see fig. 35 (a)). As a result, the sewage is rapidly discharged toward the toilet 520, and thus the sewage is splashed outside the toilet 520.

The invention aims to provide a portable toilet bowl and a portable toilet with the same, which can keep the vertical dimension of a shaft hole of a container small, fix a handle in a non-rotating manner relative to the container, and prevent the handle from being fixed when sewage is discharged by holding the handle and pouring the container.

(II) technical scheme

The portable toilet bowl of the present invention comprises: a container having an upper edge portion, a left side portion, and a right side portion that are opened upward; and a handle which is erected from a left side portion to a right side portion of the container and rotatably engaged with the container. At least one of the left side portion and the right side portion of the container is formed with a shaft hole including a circular hole and a vertical hole extending straight upward from the circular hole. The handle has a shaft inserted into the shaft hole. The shaft is rotatable in the circular hole, and is configured to move from the circular hole to the vertical hole and fit into the vertical hole when the handle is raised and lifted. The longitudinal hole has: a front edge extending linearly upward from the front end of the circular hole, and a rear edge formed rearward of the front edge and extending linearly upward. The shaft has a first linear shaft edge facing the front edge and a second linear shaft edge facing the rear edge when the shaft is fitted into the longitudinal hole. The front edge has a longer up-down length than the first axial edge.

According to the above portable toilet bowl, the shaft of the handle is rotatable inside the circular hole of the container, so that the handle can be rotated with respect to the container. When the bucket is mounted to the toilet body of the portable toilet, the handle is out of the way when the portable toilet is in use, since the handle can be laid down. On the other hand, when the handle is raised and lifted, the shaft of the handle moves from the circular hole of the container to the vertical hole and is fitted into the vertical hole. Thereby, the handle is fixed against rotation relative to the container. Therefore, the tub is easily carried in such a manner that the splashing of the sewage is prevented. When the sewage is discharged from the tub, the container is poured forward while maintaining the grip of the handle. At this time, a force inclined from the vertical hole acts on the shaft. However, in the case of the tub, the front edge of the longitudinal hole has a longer vertical length than the first axial edge of the shaft. Therefore, even if the force acts on the shaft, the lower end portion of the first shaft edge is supported by the front edge of the vertical hole, and the shaft does not come out of the vertical hole. Therefore, the container can be prevented from being steeply inclined without releasing the fixing of the handle. Accordingly, the sewage can be prevented from being rapidly discharged from the container. In addition, according to the above portable toilet bowl, the front edge of the vertical hole extends upward from the front end of the circular hole. Therefore, the vertical length of the leading edge can be ensured and the vertical dimension of the shaft hole can be suppressed.

The trailing edge may have a length up and down shorter than a length of the first axial edge.

This can further suppress the vertical dimension of the shaft hole.

The vertical hole may have a length up and down of the front edge longer than a hole width between the front edge and the rear edge of the vertical hole.

If the upper and lower lengths of the front edges of the longitudinal holes are increased in this way, the shafts are made more difficult to escape from the longitudinal holes. The handle can be more reliably prevented from being released when the container is poured.

The transverse cross-sectional shape of the shaft may be a four-sided shape having the first shaft edge, the second shaft edge, a third shaft edge connecting one end of the first shaft edge and one end of the second shaft edge, and a fourth shaft edge connecting the other end of the first shaft edge and the other end of the second shaft edge. The lengths of the first and second axial edges may be longer than the lengths of the third and fourth axial edges.

Thus, the length of the first axial edge is relatively long, and therefore the contact area between the first axial line and the front edge is relatively large. The shaft of the handle is sufficiently supported by the front edge of the longitudinal hole. Therefore, the shaft can be more reliably prevented from coming out of the longitudinal hole. The release of the fixation of the handle can be prevented more reliably.

The handle may have a stopper provided on a front end side of the shaft. The stopper may have: a stopper main body portion, at least a part of which is located inside the circular hole, as viewed in an axial direction of the shaft when the handle is put down; and a protrusion protruding upward from the stopper body portion. The protrusion may be located inside the vertical hole as viewed in the axial direction of the shaft when the handle is lowered, and may overlap with a peripheral portion of the vertical hole of the container as viewed in the axial direction of the shaft when the handle is raised and lifted.

Thus, the handle is provided with a stopper provided on the front end side of the shaft, and the protrusion of the stopper is positioned inside the vertical hole when viewed in the axial direction of the shaft in a state where the handle is put down. Therefore, the stopper is allowed to pass through the shaft hole easily, and the handle can be attached to the container easily. When the handle is lifted up, the protrusion of the stopper overlaps the peripheral portion of the vertical hole of the container as viewed in the axial direction of the shaft. Therefore, even if the handle is displaced in the axial direction of the shaft, the protrusion of the stopper abuts against the peripheral portion of the vertical hole, so that the shaft does not come out of the vertical hole, and the handle is prevented from coming out of the container. Therefore, a portable toilet bowl in which the handle is not easily detached from the container can be provided.

The stopper main body portion may be formed in a circular shape having an outer diameter larger than a hole width of the vertical hole, as viewed in an axial direction of the shaft. The transverse cross-sectional shape of the shaft may be formed in a quadrangular shape.

The shaft holes may be formed at left and right side portions of the container. The shaft and the stopper may be provided on both sides of the handle.

The protrusion may be located inside the vertical hole as viewed in the axial direction of the shaft when the handle is tilted backward, and may be located in front of the vertical hole as viewed in the axial direction of the shaft when the handle is raised and lifted.

In this way, in a state where the handle is put down rearward, the protrusion of the stopper is located inside the vertical hole, and therefore the stopper can be passed through the shaft hole. The handle can be attached to the container by tilting the handle rearward. When the handle is lifted up, the protrusion of the stopper is located in front of the vertical hole, and therefore the protrusion can engage with the front side portion of the vertical hole of the container. Thus, the handle can be prevented from being detached from the container.

The container may have an inverted U-shaped reinforcing rib protruding from a peripheral portion of the vertical hole toward one of the axial directions of the shaft. The handle may have a reinforcing portion provided on one of the first and second axial edges in the axial direction of the shaft, and may be inserted into the reinforcing rib when the handle is lifted up.

Thus, when tilting the container, the force applied from the shaft to the container is supported not only by the leading edge of the longitudinal hole but also by the reinforcing ribs. Since the peripheral portion of the longitudinal hole is not easily deformed, the shaft can be further prevented from coming out of the longitudinal hole. Therefore, the fixing of the handle can be more effectively prevented from being released when the container is tilted.

The container may have a cross rib extending forward or rearward from the reinforcing rib.

Thus, the peripheral portion of the longitudinal hole is less likely to be deformed, and the shaft is more reliably prevented from coming out of the longitudinal hole. The fixing of the handle can be prevented from being released more effectively when pouring the container.

The front-rear length of the container may be longer than the left-right length of the container.

The length in the front-rear direction between the front end of the container and the shaft hole may be longer than the length in the front-rear direction between the rear end of the container and the shaft hole.

The bottom wall of the container may be inclined so as to be more upward as it goes forward.

In the portable toilet, water is stored in the bowl to reach a predetermined water level before use. According to the above, even if the amount of water is relatively small, the water level is easily ensured in the container. Therefore, water can be saved.

The upper edge portion of the container may have: an outer peripheral wall extending upward and downward, and a liquid barrier protruding forward from a front portion of the outer peripheral wall.

Thus, when the inclined vessel discharges the sewage, the sewage flows down from the front end of the liquid-blocking plate. Inhibit sewage from flowing along the peripheral wall and inhibit the pollution of the peripheral wall. Therefore, contamination of the outer peripheral wall of the container due to discharge of sewage can be suppressed.

An outflow port recessed downward may be formed at a front end portion of the upper edge portion of the container.

Thus, when pouring the container, the contaminated water is intensively discharged from the outflow port. Therefore, the sewage is prevented from splashing to the left and right. Can well discharge sewage to a toilet, etc.

The portable toilet of the present invention is provided with the portable toilet bowl.

(III) beneficial effects

According to the present invention, a portable toilet bowl and a portable toilet provided with the same can be provided, in which the vertical dimension of the shaft hole of the container can be kept small, the handle can be fixed so as not to rotate relative to the container, and when the handle is held by hand and the container is tilted to discharge sewage, the fixation of the handle is not released.

Detailed Description

A portable toilet according to an embodiment of the present invention and a portable toilet bowl will be described below with reference to the accompanying drawings. Fig. 1 is a perspective view of a portable toilet 1 according to the present embodiment. In the following description of the portable toilet 1, the front, rear, left, right, up and down directions are respectively the front, rear, left, right, up and down directions as seen from a user seated on the toilet seat 5 described later.

(Portable toilet)

The portable toilet 1 includes: a toilet body 2, and a portable toilet bowl (hereinafter simply referred to as a bowl) 10, the bowl 10 being detachably attached to the toilet body 2.

(toilet main body)

First, the toilet body 2 will be described. The toilet body 2 includes: a chair section 3, legs 4 supporting the chair section 3, a toilet seat 5, a backrest 6, left and right armrests 7, and a cover 8. The chair section 3 is formed in a box shape that is opened upward. The tub 10 is installed inside the chair section 3. The toilet seat 5 is rotatably mounted to the rear of the chair section 3. When the toilet seat 5 is rotated forward, the toilet seat 5 can be horizontally lowered, and a user can sit on the toilet seat 5. When the toilet seat 5 is rotated upward, the toilet seat 5 can be raised, and the inside of the chair section 3 can be opened. By setting the toilet seat 5 in a raised state, the bucket 10 can be removed upward from the chair section 3, and the bucket 10 can be attached to the chair section 3 from above.

The toilet body 2 shown in fig. 1 is only an example. The structure of the toilet main body 2 is not particularly limited as long as the bucket 10 is detachably mounted. Nor is it necessary that the armrest 7, backrest 6, or cover 8 be present. When the chair section 3 is formed to be directly placed on the ground, the legs 4 may be omitted.

(barrel)

Next, the tub 10 will be described. In the following description of the bowl 10, front, rear, left, and right refer to the front, rear, left, and right directions as viewed from a user seated on the toilet seat 5 when the bowl 10 is mounted to the toilet body 2. Upper and lower represent upper and lower when the tub 10 is placed on a horizontal plane. Reference numeral F, re, L, R, U, D in the drawings indicates front, rear, left, right, upper, and lower, respectively.

Unless otherwise specified, the front direction means not only the forward direction in the horizontal direction but also a direction inclined at an angle smaller than 90 degrees from the left to the right. The rear direction means not only a backward direction in the horizontal direction but also a direction inclined at an angle smaller than 90 degrees from the left and right of the direction. The left direction means not only a horizontal direction toward the left but also a direction inclined at an angle smaller than 90 degrees from the direction toward the front and back. The right direction means not only a horizontal direction toward the right but also a direction inclined at an angle of less than 90 degrees from the direction toward the front and back. The upward direction includes not only the upward direction in the vertical direction but also a direction inclined at an angle smaller than 90 degrees from the direction. The lower direction includes not only the downward direction in the vertical direction but also a direction inclined at an angle smaller than 90 degrees from the direction forward and backward.

Fig. 2 is a perspective view of the tub 10 of the present embodiment. The tub 10 has a container 20 and a handle 50. The container 20 has an upper edge 22 that opens upward. The handle 50 spans from the left portion to the right portion of the container 20. Handle 50 is mounted to container 20 so as to span upper edge 22. The handle 50 is rotatably engaged with the container 20 about an axis C1, which will be described in detail later.

(Container)

Fig. 3, 4, 5, and 6 are top, left, rear, and bottom views, respectively, of container 20. Fig. 7 is a longitudinal cross-sectional view of the container 20, taken along line VII-VII of fig. 5. Fig. 8 is a horizontal cross-sectional view of the container 20, taken along line VIII-VIII of fig. 4. As shown in fig. 7, the container 20 includes: the bottom wall 24, a peripheral wall 26 extending upward from the bottom wall 24, an upper edge 22 located above the peripheral wall 26, and annular legs 28 provided on the lower side of the bottom wall 24.

As shown in fig. 3, the bottom wall 24 is formed in a circular shape as viewed from above. As shown in fig. 7, the bottom wall 24 is formed in a concave shape recessed downward. In the present embodiment, the bottom wall 24 has: a horizontal wall 24A extending horizontally and having a circular shape when viewed from above, and an inclined wall 24B inclined obliquely upward from the outer peripheral end of the horizontal wall 24A.

However, the shape of the bottom wall 24 is not particularly limited. As shown in fig. 9, the bottom wall 24 may also be concavely curved. The bottom wall 24 may be formed without a bent portion. In this case, the bottom wall 24 is also formed in a circular shape as viewed from above. The bottom wall 24 may also be formed in a hemispherical shape.

As shown in fig. 10, the bottom wall 24 may be inclined so as to be more upward as it goes forward. In this case, the bottom wall 24 may be formed in a circular shape when viewed from above.

As shown in fig. 8, the peripheral wall 26 has: a rear side peripheral wall 26A having an arc-shaped horizontal cross section, and a front side peripheral wall 26B extending forward from the rear side peripheral wall 26A and having a convex horizontal cross section forward. As shown in fig. 4, the outline of the front side peripheral wall 26B has a portion 26BL curved so as to have a smaller inclination angle α with respect to the horizontal line as seen from the side. The proportion of the curved portion 26BL in the entire contour of the front side peripheral wall 26B is not particularly limited, but is preferably 50% or more, and more preferably 65% or more. In the present embodiment, the content is 80% or more. The entire contour of the front side peripheral wall 26B may be the curved portion 26BL.

As shown in fig. 7, an upper vertical wall 26BU is provided above a portion 26BL curved so as to have a smaller inclination angle α with respect to the horizontal line as going upward. The upper vertical wall 26BU is a substantially vertical wall. The upper vertical wall 26BU may extend vertically or may be slightly inclined from the vertical plane. For example, the upper vertical wall 26BU may be inclined at an angle of within ±10 degrees, preferably within ±5 degrees, from the vertical plane. The upper vertical wall 26BU functions as follows: when the portable toilet 1 is used, urine is prevented from being splashed forward of the container 20 due to the potential of urination. From the viewpoint of preventing urine splash, the vertical dimension of the upper vertical wall 26BU is preferably 3mm or more, more preferably 8mm or more. On the other hand, if the upper and lower dimensions of the upper vertical wall 26BU are large, there is a tendency that: when the waste water is discharged by tilting the container 20 forward after the portable toilet 1 is used, the last waste water left is splashed up near the upper vertical wall 26BU, and is likely to be splashed by striking the upper vertical wall 26BU. From the viewpoint of preventing such splashing of sewage, the vertical dimension of the upper vertical wall 26BU is preferably 30mm or less, more preferably 20mm or less. If the vertical dimension of the upper and lower vertical walls 26BU is 17mm or less, the waste water can be further prevented from splashing.

Fig. 11 is a vertical cross-sectional view of the front peripheral wall 26B, and is a cross-sectional view taken along line XI-XI of fig. 4. The vertical cross section shown in fig. 11 is a vertical cross section of the front side peripheral wall 26B at a position intermediate between the rear end 26Bb of the front side peripheral wall 26B and the front end 20f of the container 20. As shown in fig. 11, the front side peripheral wall 26B has: a lower wall portion 27D, a left wall portion 27L extending upward from a left end of the lower wall portion 27D, and a right wall portion 27R extending upward from a right end of the lower wall portion 27D. As shown in fig. 3, a flow path 27 extending in the front-rear direction as viewed from above is formed by the lower wall portion 27D, the left wall portion 27L, and the right wall portion 27R.

The width W27 of the flow path 27 is relatively large. The left-right width W27 of the flow path 27 here means: the width of the flow path 27 is about the cross section (the cross section at the intermediate position between the rear end 26Bb of the front side peripheral wall 26B and the front end 20f of the container 20). The width W27 of the flow path 27 is greater than half the radius r24 of the bottom wall 24. The width W27 of the flow path 27 is larger than the radius r24A of the horizontal wall 24A of the bottom wall 24. Here, the width W27 of the flow path 27 is larger than the radius r24 of the bottom wall 24. The width W27 of the flow path 27 is larger than the radius r28 (see fig. 6) of the annular leg 28. Further, the radius of the annular leg 28 refers to 1/2 of the inner diameter of the annular leg 28. The annular leg 28 is formed in a substantially annular shape as viewed from below. The substantially annular form includes: a shape (i.e., strictly annular) that surrounds the center 24C of the bottom wall 24; and a shape in which a notch 28a is provided in a part of the ring shape as shown in fig. 6.

The upper limit of the width W27 of the flow path 27 is not particularly limited, but is preferably 170mm or less, for example. Thus, even with respect to the relatively small water storage portion of a standard sum toilet, it is easy to pour continuously without spilling sewage.

The portable toilet 1 is recommended to store a predetermined volume of water in the bowl 10 before use. As shown in fig. 7, a step 25 is provided on the peripheral wall 26 as a mark to indicate the water surface position when a predetermined volume of water is stored in the container 20. The step 25 is provided at a water surface position when 1 liter of water is stored in the container 20. Since a sufficient water level can be ensured if 1 liter of water is stored, it is generally possible to submerge feces and to suppress the generation of odor. The step 25 is provided on the rear side peripheral wall 26A, but may be provided on the front side peripheral wall 26B. The mark is not limited to the step 25 as long as it can be visually confirmed. Instead of the step 25, a groove, a protrusion, or the like may be used as the mark. Further, colored lines, figures, characters, marks, and the like may be used as the marks. However, if the step 25 is used as a mark, visual visibility can be ensured even if dirt is deposited, and the mark does not disappear after long-term use, which is particularly preferable.

As shown in fig. 7, the upper edge 22 includes: an inner peripheral wall 22A located above the peripheral wall 26, an upper wall 22B extending outward from an upper end of the inner peripheral wall 22A, and an outer peripheral wall 22C extending downward from an outer end of the upper wall 22B. The upper edge 22 is formed in a shape folded back downward from the inside toward the outside. The upper edge 22 is formed in an inverted U-shape in cross section. The inner peripheral wall 22A may be identical to the upper vertical wall 26BU, or may be a part of the upper vertical wall 26 BU.

As shown in fig. 4, shaft holes 30 for engaging handles 50 (see fig. 2) are formed in left and right portions of the container 20. Here, the shaft hole 30 is formed in left and right side portions of the outer peripheral wall 22C of the upper edge portion 22.

As shown in fig. 12, the shaft hole 30 includes: a circular hole 31, and a vertical hole 32 extending upward from the circular hole 31. The virtual line 30S in fig. 12 is a line indicating the boundary between the circular hole 31 and the vertical hole 32. The circular hole 31 is an example of a lower hole located below, and the vertical hole 32 is an example of an upper hole extending upward from the lower hole. The vertical hole 32 extends straight upward from the circular hole 31. The vertical hole 32 has: a front edge 32f and a rear edge 32b extending in a straight line upward and downward, and an upper edge 32t connecting upper ends of the front edge 32f and the rear edge 32 b. The upper edge 32t extends horizontally. The trailing edge 32b is formed rearward of the leading edge 32f and opposite the leading edge 32 f. In the present embodiment, the front edge 32f extends upward from the front end 31f of the circular hole 31. The shaft hole 30 is formed in a b-shape. A center line (a line extending upward and downward through the middle of the leading edge 32f and the trailing edge 32 b) 32CL of the vertical hole 32 is offset from the center 31C of the circular hole 31 toward the leading edge 32 f. The up-down length H32f of the leading edge 32f is longer than the aperture width W32 between the leading edge 32f and the trailing edge 32 b.

As shown in fig. 13, an inverted U-shaped reinforcing rib 34 protruding outward is provided at the peripheral portion of the vertical hole 32 of the outer peripheral wall 22C. The reinforcing rib 34 protrudes from the outer peripheral wall 22C in one axial direction. Specifically, reinforcing ribs 34 protruding leftward are provided at the peripheral portion of the left-side vertical hole 32, and reinforcing ribs 34 protruding rightward are provided at the peripheral portion of the right-side vertical hole 32. The reinforcing rib 34 has: a front rib 34A located forward of the longitudinal hole 32, a rear rib 34B located rearward of the longitudinal hole 32, and an upper rib 34T located above the longitudinal hole 32. Further, an arcuate reinforcing rib 35 protruding outward is also provided at the peripheral portion of the circular hole 31. The reinforcing rib 34 is connected with the reinforcing rib 35. In the present embodiment, the reinforcing rib 34 and the reinforcing rib 35 are formed so as to surround the shaft hole 30 as a whole.

The outer peripheral wall 22C is provided with lateral ribs 36A and 36B extending forward and rearward from the reinforcing rib 34. The cross rib 36A is formed above the cross rib 36B. The front-rear length of the lower cross rib 36B is longer than the front-rear length of the upper cross rib 36A.

As shown in fig. 4 and 5, a grip 40 protruding rearward is provided at a central portion of the upper edge 22 in the lateral direction at the rear side thereof. Fig. 14 is a longitudinal cross-sectional view of the grip 40, and is an enlarged view of the XIV portion of fig. 7. As shown in fig. 14, the grip 40 has: a curved wall 41 extending rearward and downward from the lower end of the outer peripheral wall 22C, a lateral wall 42 extending rearward from the rear end of the curved wall 41, and a longitudinal wall 43 extending downward from the rear end of the lateral wall 42. As shown in fig. 5, the grippers 40 each include: a curved wall 41, a transverse wall 42, and left and right walls 44L and 44R provided to the left and right of the vertical wall 43. In the present embodiment, the horizontal wall 42 extends in the horizontal direction, and the vertical wall 43 extends in the vertical direction. However, the lateral wall 42 may be slightly inclined from the horizontal direction, and the vertical wall 43 may be slightly inclined from the vertical direction.

The length W40 (see fig. 5) of the gripper 40 is set to be at least three fingers. Here, the length W40 of the grip 40 is set to 35mm or more. Further, the left and right length W40 of the grip is the inner dimension of the grip 40. That is, it is the spacing between the right side of the left wall 44L of the grip 40 and the left side of the right wall 44R. As shown in fig. 14, the length H43 of the vertical wall 43 is 2mm or more, preferably 4mm or more, for easy hooking of the grip 40. The radius of curvature R of the curved wall 41 is at least 1mm or more, preferably 3mm or more. The radius of curvature R of the curved wall 41 is preferably 30mm or less.

Fig. 15 is an enlarged cross-sectional view of the front end portion of the container 20, and is an enlarged view of the XV portion in fig. 7. As shown in fig. 15, a liquid barrier 23 protruding forward from the front portion of the outer peripheral wall 22C is provided at the upper edge 22 of the container 20. Here, the liquid-repellent plate 23 is formed flush with the upper wall 22B.

As shown in fig. 2, the front-rear length of the container 20 is longer than the left-right length of the container 20. As shown in fig. 4, the length L20f in the front-rear direction between the front end 20f of the container 20 and the shaft hole 30 is longer than the length L20b in the front-rear direction between the rear end 20b of the container 20 and the shaft hole 30. The length in the front-rear direction between the front end 20f of the container 20 and the shaft hole 30 is: a length in the front-rear direction between the front end 20f of the container 20 and the central position in the front-rear direction of the shaft hole 30 (here, the position of the center 31C of the circular hole 31). Similarly, the length in the front-rear direction between the rear end 20b of the container 20 and the shaft hole 30 means: a length in the front-rear direction between the rear end 20b of the container 20 and the central position in the front-rear direction of the shaft hole 30 (here, the position of the center 31C of the circular hole 31).

The above is the structure of the container. Next, the handle 50 will be described. Fig. 16 is a perspective view of the handle 50. Fig. 17 is an enlarged view of the XVII portion of fig. 16.

(handle)

As shown in fig. 16, the handle 50 has: a handle 51, and engagement portions 52 provided at both end portions of the handle 51. The engaging portion 52 is a portion that engages with the shaft hole 30 of the container 20. As shown in fig. 17, the engaging portion 52 extends inward from the front end portion of the shank 51. The engaging portion 52 includes: the shaft 54, a stopper 56 provided inside the shaft 54, and a reinforcing portion 58 provided outside the shaft 54. The stopper 56 is provided on the front end side of the shaft 54. Specifically, the engagement portion 52 on the right side of the handle 50 includes: the reinforcing portion 58, the shaft 54 provided to the left of the reinforcing portion 58, and the stopper 56 provided to the left of the shaft 54. The left engaging portion 52 of the handle 50 includes: the reinforcing portion 58, the shaft 54 provided to the right of the reinforcing portion 58, and the stopper 56 provided to the right of the shaft 54.

The shaft 54 is formed in a quadrangular prism shape. As shown in fig. 18, the transverse cross-sectional shape of the shaft 54 is formed in a quadrangular shape. The quadrangle described here includes not only a strict quadrangle having right angles at corners, but also a quadrangle having rounded corners at corners as shown in fig. 18. The shaft 54 has: the first shaft edge 54a, a second shaft edge 54b located on the opposite side of the first shaft edge 54a, a third shaft edge 54c connecting one end of the first shaft edge 54a with one end of the second shaft edge 54b, and a fourth shaft edge 54d connecting the other end of the first shaft edge 54a with the other end of the second shaft edge 54 b. The first and second edges 54a, 54b are longer than the third and fourth edges 54c, 54d.

Since the handle 50 is rotatably engaged with the container 20, the handle 50 can be tilted forward as shown in fig. 19. Further, as shown in fig. 20, the handle 50 can be raised. Further, the handle 50 can be tilted backward as shown in fig. 21. When the handle 50 is tilted backward, the handle 50 is placed on the lateral wall 42 of the grip 40. When the handle 50 is put down backward, the handle 50 is supported by the grip 40.

The shaft 54 is inserted into the shaft hole 30. The shaft 54 is formed in a size capable of rotating within the circular hole 31. The maximum dimension L54 (here, the diagonal dimension, see fig. 18) of the transverse cross section of the shaft 54 is smaller than the inner diameter of the circular hole 31. When the shaft 54 is positioned in the circular hole 31, the handle 50 can be turned. In a state where the handle 50 is laid down, the shaft 54 is disposed in the circular hole 31.

When the handle 50 is raised and lifted (see fig. 20), the shaft 54 moves from the circular hole 31 to the vertical hole 32 and is fitted into the vertical hole 32 as shown in fig. 22. When the shaft 54 is inserted into the longitudinal bore 32, rotation of the shaft 54 is limited by the longitudinal bore 32. Therefore, when the handle 50 is raised and lifted, the handle 50 cannot be rotated. The shaft 54 and the vertical hole 32 constitute a locking mechanism 55 for fixing the handle 50 so as not to rotate relative to the container 20 when the handle 50 is raised and lifted.

When the shaft 54 is fitted into the longitudinal hole 32, the first shaft edge 54a faces the front edge 32f of the longitudinal hole 32, and the second shaft edge 54b faces the rear edge 32b of the longitudinal hole 32. The third axial edge 54c abuts against the upper edge 32t of the vertical hole 32. The hole width W32 (see fig. 12) of the vertical hole 32 is equal to the length H54c of the third axial edge 54c or is slightly larger than the length H54c of the third axial edge 54 c. The upper and lower length H32f of the front edge 32f of the longitudinal hole 32 is longer than the length H54a of the first axial edge 54 a. The up-down length H32b of the trailing edge 32b of the longitudinal hole 32 is shorter than the length H54a of the first axial edge 54 a.

As shown in fig. 18, the reinforcing portion 58 is formed in a quadrangular prism shape like the shaft 54. The reinforcing portion 58 is formed in a quadrangular shape larger than the shaft 54 by one turn in transverse cross-sectional shape. As shown in fig. 22, when the shaft 54 is fitted into the longitudinal hole 32, the reinforcing portion 58 is inserted into the inside of the reinforcing rib 34. The reinforcing portion 58 is embedded inside the reinforcing rib 34 and contacts the reinforcing rib 34.

As shown in fig. 17, the stopper 56 has: a disk-shaped stopper main body portion 56A, and a projection portion 56B projecting from the stopper main body portion 56A. The stopper 56 is formed in a b-shape as viewed from the axial direction of the shaft 54. The stopper 56 is provided to prevent the engagement portion 52 of the handle 50 from being disengaged from the shaft hole 30. Fig. 23 to 25 are diagrams schematically showing the shaft hole 30, the stopper 56, and the shaft 54 when viewed in the axial direction of the shaft 54. Fig. 23 to 25 are views of the right outer peripheral wall 22C of the container 20 from the back side (in other words, views of the right outer peripheral wall 22C of the container 20 from the left side to the right side).

As shown in fig. 23, at least a part of the stopper main body portion 56A is located inside the circular hole 31 as viewed from the axial direction when the handle 50 is laid down. The stopper main body portion 56A may be formed in a circular shape having an outer diameter equal to or smaller than the inner diameter of the circular hole 31 as seen in the axial direction, but is formed in a circular shape having an outer diameter slightly larger than the inner diameter of the circular hole 31. The outer diameter D56A of the stopper main body portion 56A is larger than the hole width W32 of the vertical hole 32.

When the handle 50 is tilted rearward as shown in fig. 21, the projection 56B projects upward from the stopper main body portion 56A as viewed in the axial direction as shown in fig. 23. When the handle 50 is tilted rearward, the projection 56B is located inside the vertical hole 32 as viewed from the axial direction. The container 20 is made of resin and has elasticity. When the stopper 56 is inserted into the shaft hole 30 in a state where the handle 50 is put down backward, the round hole 31 is temporarily expanded by the stopper main body portion 56A. Therefore, the stopper main body portion 56A can pass through the circular hole 31. Further, since the protrusion 56 is located inside the vertical hole 32, it can pass through the vertical hole 32 directly. Therefore, by pressing the stopper 56 against the shaft hole 30 from the front side in a state where the handle 50 is tilted backward, the stopper 56 can be disposed on the rear side of the shaft hole 30 (in other words, on the inner side of the outer peripheral wall 22C).

As shown in fig. 24, when the handle 50 is rotated from the lowered state, the protrusion 56B moves to the outside of the shaft hole 30 as viewed from the axial direction. The projection 56B overlaps with the peripheral portion of the shaft hole 30 of the outer peripheral wall 22C as viewed from the axial direction. Since the projection 56B abuts against the peripheral portion of the shaft hole 30, the handle 50 is restricted from being displaced in the axial direction, and the handle 50 is prevented from being detached from the shaft hole 30.

When the handle 50 is raised and lifted as shown in fig. 20, the shaft 54 moves from the circular hole 31 to the vertical hole 32 as shown in fig. 25. The projection 56B is located in front of the vertical hole 32 as viewed from the axial direction. In this case, the projection 56B also overlaps with the peripheral portion of the shaft hole 30 of the outer peripheral wall 22C as viewed from the axial direction. Thereby preventing the handle 50 from being detached from the shaft hole 30.

When the portable toilet 1 is used, the user lifts up the handle 50 and lifts up, thereby removing the bowl 10 from the toilet body 2. And, the user holds the handle 50 and moves it, thereby carrying the tub 10 to the toilet. As described above, the length L20f of the front portion of the shaft hole 30 of the container 20 is longer than the length L20b of the rear portion of the shaft hole 30 (see fig. 4). However, the front side peripheral wall 26B is inclined obliquely upward forward as viewed from the side. When water having a predetermined amount or less is stored in the container 20, the position of the center of gravity of the container 20 and the water as a whole in the front-rear direction is located in the vicinity of the shaft hole 30 regardless of the water level. That is, when water having a predetermined volume or less is stored in the container 20, the center of gravity of the total of the container 20 and the water is located substantially directly below the shaft hole 30, and even if the water level changes, the front-rear position of the center of gravity is less fluctuated.

Since it becomes difficult to carry the bucket 10 if the storage amount of the container 20 is excessive, an upper limit value of the storage volume of the container 20 is often set in advance for the portable toilet 1. The predetermined volume may be equal to an upper limit value of the storage volume of the container 20, for example. But is not limited thereto. The predetermined volume may be smaller than the upper limit value of the storage volume of the container 20. Here, as shown in fig. 20, when water having 50% or less of the internal volume of the container 20 is stored in the container 20, the position of the center of gravity of the container 20 and the water as a whole in the front-rear direction is located between a position P1 10mm forward from the front end of the shaft hole 30 and a position P2 10mm rearward from the rear end of the shaft hole 30, irrespective of the water level.

As described above, the tub 10 is formed such that even if the water level changes, the front-rear position of the center of gravity is less fluctuated, but there are cases where: when the tub 10 is detached from the toilet body 2 or the tub 10 is carried, the tub 10 may be inclined due to shaking or contact with furniture or the like. Depending on the shape of the container 20, there may be the following: the gravity center moves to the tilt side, and the gravity plays a role in promoting the tilt. In this case, there is a possibility that the inclination becomes large and the sewage overflows from the container 20. For example, the following are the cases: at a position distant from the vertical plane passing through the axis C1 (see fig. 2) of the shaft hole 30, there is a storage angle shape capable of storing water on the inclined side. However, the shape of the container 20 is designed to reduce the volume of water accumulated on the inclined side, so that the above phenomenon can be avoided. For example, in order to reduce the angle between the bottom forming the accumulation angle and the front and rear walls, the bottom may be angled, curved or spherical between the bottom and the front and rear walls, or the bottom may be deepened, thereby avoiding the above-described phenomenon.

In the present embodiment, the container 20 is formed as follows. In fig. 26 (a) to (C), a plumb line VP represents a plumb plane passing through the axis C1 of the shaft hole 30. The angle θ represents the inclination angle of the container 20 with respect to the horizontal plane. Reference numeral G denotes the position of the center of gravity of the container 20 and the water as a whole. In the present embodiment, when water having 50% or less of the internal volume of the container 20 is stored in the container 20, as shown in fig. 26 (b), the center of gravity G is located further forward than the vertical plane VP at least when the container 20 is inclined rearward and downward at an angle θ of more than 0 degrees and less than 20 degrees with respect to the horizontal plane. In addition, when water having 50% or less of the internal volume of the container 20 is stored in the container 20, as shown in fig. 26 (c), at least when the container 20 is inclined forward and downward at an angle θ of more than 0 degrees and less than 20 degrees with respect to the horizontal plane, the center of gravity G is located further rearward than the vertical plane VP.

According to the present embodiment, when the bowl 10 is detached from the toilet main body 2 or when the bowl 10 is carried, at least when the container 20 is tilted at an angle smaller than 20 degrees, gravity acts to restore the tilt. Thereby preventing the inclination from becoming large and inhibiting the overflow of sewage from the container 20. In addition, the container 20 may be configured such that even when it is inclined at an angle of 20 degrees or more, gravity acts to restore the inclination.

The above is the configuration of the portable toilet 1 and the bowl 10 according to the present embodiment. Next, an example of a method of using the tub 10 will be described.

(method of Using barrel)

When the user uses the portable toilet 1, sewage is accumulated in the bowl 10. To pour out the contaminated water of the bowl 10, the user first lifts the handle 50 up and lifts up, thereby removing the bowl 10 from the toilet body 2. At this time, the shaft 54 of the handle 50 is fitted into the longitudinal hole 32 of the container 20, and the handle 50 is fixed to the container 20 so as not to rotate. Therefore, the user can easily detach the tub 10.

Then, the user holds the handle 50 to move to the toilet. At this time, since the handle 50 is fixed to the container 20 so as not to rotate, the container 20 can be restrained from shaking. In addition, even if the container 20 hits furniture or the like during transportation, the container does not greatly incline. Therefore, it is possible to prevent the overflow of the sewage when the tub 10 is carried.

After reaching the toilet, the user discharges the sewage of the bowl 10 to the toilet bowl of the toilet. The operation of discharging the sewage from the bowl 10 to the toilet bowl will be described with reference to fig. 27 to 29. Fig. 27 (a), 28 (a) and 29 (a) are side views schematically showing a bowl and a toilet bowl, and fig. 27 (b), 28 (b) and 29 (b) are views schematically showing a shaft and a shaft hole.

As shown in fig. 27 (a), the user holds the handle 50 with one hand h1 above the toilet 60 and hooks the other hand h2 to the grip 40 of the container 20 from below. Then, the container 20 is tilted forward together with the handle 50 by lifting the grip 40.

As shown in fig. 28 (a), the sewage in the container 20 is rapidly discharged to the toilet bowl by gradually increasing the inclination of the container 20. At this time, as shown in fig. 28 b, the shaft 54 of the handle 50 is pressed by the peripheral portion of the vertical hole 32, and a force tilting from the vertical hole 32 acts on the shaft 54 (see arrow A1). However, since the vertical length of the front edge 32f of the vertical hole 32 is longer than the length of the first shaft edge 54a of the shaft 54, even if the shaft 54 is inclined, the lower end 54ad of the first shaft edge 54a is kept supported by the front edge 32f of the vertical hole 32. Thus, the shaft 54 is prevented from coming out of the longitudinal hole 32.

Therefore, as shown in fig. 29 (a) and (b), even if the container 20 is greatly tilted, the shaft 54 does not come out of the vertical hole 32, and the fixation of the handle 50 is not released. The container 20 can be poured at the user's intention in a state where the handle 50 is kept fixed. If the fixing of the handle 50 is accidentally released during tilting of the container 20, there is a possibility that the container 20 is suddenly and severely tilted, and sewage is rapidly discharged to be splashed outside the toilet 60. However, according to the present embodiment, such a situation can be prevented.

After discharging the contaminated water from the container 20 as described above, the user washes the tub 10. At this time, for example, the tub 10 is placed on a floor of a washing table or bath, etc., and the handle 50 is backwardly Fang Fangdao. This allows the inside of the container 20 to be cleaned without being obstructed by the handle 50.

After the user washes the tub 10, a predetermined volume of water is stored in the container 20. Then, the handle 50 is raised and lifted, and the tub 10 is carried by holding the handle 50 and mounted to the toilet main body 2. Thereafter, the handle 50 is placed back and the toilet seat 5 is placed forward (see fig. 1). Thereby, the portable toilet 1 can be reused. The operation of accumulating water in the container 20 is not limited to being performed before the toilet bowl 10 is mounted on the toilet main body 2, and may be performed after the toilet main body 2 is mounted.

The above is an example of the method of using the tub 10. Further, although the sewage of the bowl 10 is set to be discharged to the toilet 60 of the toilet here, the sewage discharge place is not limited to the toilet of the toilet.

(effects of the embodiment)

Next, various effects achieved by the present embodiment will be described.

As described above, according to the tub 10 of the present embodiment, since the shaft 54 of the handle 50 can rotate inside the circular hole 31 of the container 20, the handle 50 can rotate with respect to the container 20. When the bucket 10 is mounted to the toilet body 2 of the portable toilet 1, the handle 50 can be put down backward (see fig. 1), so that the handle 50 is out of the way when the portable toilet 1 is used. On the other hand, when the handle 50 is raised and lifted, the shaft 54 of the handle 50 moves from the circular hole 31 of the container 20 toward the vertical hole 32 and is fitted into the vertical hole 32. Thus, the handle 50 is fixed against rotation relative to the container 20. Therefore, the user can easily carry the tub 10 in such a manner as to prevent the overflow of the sewage.

When the contaminated water is discharged from the tub 10, the state of grasping the handle 50 is maintained and the container 20 is poured. According to the tub 10 of the present embodiment, the upper and lower length H32f of the front edge 32f of the longitudinal hole 32 is longer than the length H54a of the first axial edge 54a of the shaft 54. Therefore, during pouring of the container 20, the lower end portion of the first shaft edge 54a is held by the front edge 32f, and the shaft 54 does not come out of the vertical hole 32 (see fig. 28 (b) and 29 (b)). Therefore, the fixing of the handle 50 is not released, and the container 20 can be prevented from being abruptly inclined when the container 20 is poured. Accordingly, the sewage can be prevented from being rapidly discharged from the container 20. Can prevent the sewage from splashing outside the toilet 60.

In the present embodiment, as shown in fig. 12, the shaft hole 30 is formed in a b-shape when viewed from the axial direction of the shaft 54. The center line 32CL of the vertical hole 32 is offset from the center 31C of the circular hole 31 toward the front edge 32 f. In the case where the vertical hole 32 is formed such that the center line 32CL passes through the center 31C of the circular hole 31, if the vertical length H32f of the leading edge 32f is to be ensured to be the same length, the vertical length of the shaft hole 30 needs to be lengthened. When the center line 32CL passes through the center 31C of the circular hole 31, the vertical length of the shaft hole 30 is equal to the vertical length H31 of the circular hole 31 plus the vertical length H32f of the leading edge 32 f. However, according to the present embodiment, the vertical length of the shaft hole 30 is shorter than the sum of the vertical length H31 of the circular hole 31 and the vertical length H32f of the leading edge 32 f. Therefore, the vertical dimension of the entire shaft hole 30 can be suppressed, and the vertical length of the leading edge 32f can be ensured. According to the present embodiment, the shaft hole 30 that achieves the aforementioned effects can be miniaturized.

In the present embodiment, the vertical length H32b of the trailing edge 32b of the vertical hole 32 is shorter than the length H54a of the first axial edge 54 a. This can further suppress the vertical dimension of the shaft hole 30.

Although not particularly limited, in the present embodiment, the vertical length H32f of the front edge 32f is longer than the hole width W32 between the front edge 32f and the rear end 32b of the vertical hole 32. The shaft 54 is configured to be relatively difficult to disengage from the longitudinal bore 32. Therefore, the handle 50 can be more reliably prevented from being released from being fixed when pouring the container 20.

According to the present embodiment, the shaft 54 is formed in a quadrangular cross-sectional shape, and the lengths of the first shaft edge 54a and the second shaft edge 54b are longer than those of the third shaft edge 54c and the fourth shaft edge 54 d. Since the length of the first axial edge 54a is relatively long, the contact area of the first axial edge 54a with the leading edge 32f is relatively large. The shaft 54 is sufficiently supported by the leading edge 32f of the longitudinal bore 32. Therefore, when pouring the container 20, the shaft 54 can be more reliably prevented from coming out of the vertical hole 32, and the fixing of the handle 50 can be more reliably prevented from being released.

According to the present embodiment, the handle 50 includes the stopper 56 provided on the front end side of the shaft 54, and the protrusion 56B of the stopper 56 is located inside the vertical hole 32 as viewed from the axial direction of the shaft 54 in a state where the handle 50 is put down rearward. Therefore, the stopper 56 can be easily passed through the shaft hole 30, and the handle 50 can be easily attached to the container 20. In a state where the handle 50 is raised and lifted, the projection 56B of the stopper 56 overlaps the peripheral portion of the vertical hole 32 of the container 20 as viewed from the axial direction of the shaft 54. Therefore, even if the handle 50 is offset from the axial direction of the shaft 54, the protrusion 56B of the stopper 56 abuts the peripheral portion of the vertical hole 32, so that the shaft 54 does not come out of the shaft hole 30, and the handle 50 can be prevented from coming out of the container 20. Thus, the handle 50 is not easily removed from the container 20.

According to the present embodiment, the container 20 has the reinforcing rib 34 in the shape of an inverted U, and the shaft 54 has the reinforcing portion 58 inserted into the inside of the reinforcing rib 34 when the handle 50 is raised and lifted. Accordingly, when tilting the container 20, the force applied from the handle 50 to the container 20 is supported not only by the front edge 32f of the longitudinal hole 32 but also by the reinforcing rib 34. Since the peripheral portion of the longitudinal hole 32 is not easily deformed, the shaft 54 can be further prevented from coming out of the longitudinal hole 32. Accordingly, the fixing of the handle 50 can be more effectively prevented from being released when pouring the container 20.

According to the present embodiment, the container 20 further has a cross rib 36A extending forward and rearward of the longitudinal hole 32 from the reinforcing rib 34. Therefore, the peripheral portion of the longitudinal hole 32 is less likely to be deformed, and the shaft 54 is more reliably prevented from coming out of the longitudinal hole 32. The fixing of the handle 50 can be more effectively prevented from being released when pouring the container 20.

The portable toilet 1 stores water in the bowl 10 to reach a predetermined water level before use. As shown in fig. 10, if the bottom wall 24 of the container 20 is inclined so as to be more upward as it goes forward, the water level in the container 20 is easily ensured even if the amount of water is relatively small. Thus saving water.

As shown in fig. 15, the upper edge 22 of the container 20 has a liquid barrier 23 protruding forward from the front of the outer peripheral wall 22C. Therefore, when the container 20 is tilted forward to discharge the sewage, the sewage flows down from the front end of the liquid barrier 23. The flow of sewage along the outer peripheral wall 22C and the front peripheral wall 26B is suppressed. Contamination of the outer peripheral wall 22C and the front peripheral wall 26B can be suppressed. Therefore, contamination of the outer peripheral wall 22C and the front side peripheral wall 26B of the container 20 due to discharge of sewage can be suppressed.

(other embodiments)

An embodiment of the present invention has been described above, but the above embodiment is merely an example. The invention can also be implemented in other various ways. Next, examples of other embodiments will be briefly described.

In the above embodiment, the stopper 56 is inserted into the shaft hole 30 in a state where the handle 50 is placed backward (see fig. 23), but as shown in fig. 30, the stopper 56 may be inserted into the shaft hole 30 in a state where the handle 50 is placed forward. That is, when the handle 50 is tilted forward, the protrusion 56B of the stopper 56 may be located inside the vertical hole 32 as viewed in the axial direction. In this case, the handle 50 can be attached to the container 20 by tilting the handle 50 forward. When the handle 50 is put down rearward when the container 20 is mounted on the toilet body 2 or placed on the floor or the like, the projection 56B of the stopper 56 is positioned below the circular hole 31, and the projection 56B can engage with the lower portion of the circular hole 31.

Therefore, the handle 50 can be prevented from being detached from the container 20 not only when the handle 50 is lifted but also when the handle 50 is put down backward.

In the above embodiment, the outflow port is not formed in the upper edge 22 of the container 20 as shown in fig. 3, but as shown in fig. 31, the outflow port 29 recessed downward may be formed in the front end portion of the upper edge 22 of the container 20. Thus, when the container 20 is poured forward, the sewage is intensively discharged from the outflow port 29. Therefore, the waste water can be prevented from splashing to the left and right, and the waste water can be discharged to the toilet well.

The shapes of the bottom wall 24 and the peripheral wall 26 of the container 20 are merely illustrative, and are not limited in any way.

The transverse cross-sectional shape of the shaft 54 is not limited to a quadrilateral shape. As the transverse cross-sectional shape of the shaft 54, any shape having a linear first shaft edge 54a and second shaft edge 54b may be used.

The vertical length H32b of the trailing edge 32b of the vertical hole 32 may be equal to the length H54a of the first axial edge 54a or may be longer than the length H54a of the first axial edge 54 a.

The vertical length H32f of the front edge 32f of the vertical hole 32 may be equal to or less than the hole width W32 of the vertical hole 32.

The length of the first and second edges 54a, 54b of the shaft 54 may be less than the length of the third and fourth edges 54c, 54 d.

The reinforcing ribs 34 may also be absent. The cross ribs 36A or 36B may be absent.

The length L20f in the front-rear direction between the front end 20f of the container 20 and the shaft hole 30 may be equal to the length L20b in the front-rear direction between the rear end 20b of the container 20 and the shaft hole 30, or may be shorter than the length L20 b.

The liquid barrier 23 of the container 20 may be omitted.
