At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
An animal toilet having a vertical direction, a horizontal direction, and a vertical direction perpendicular to each other,
An upper container provided with a plurality of holes through which urine passes downward;
A lower container disposed below the upper container and having an insertion port formed on the front surface in the longitudinal direction;
A tray accommodated in the lower container from the insertion port so that it can be pulled out forward;
An absorbent sheet placed on the bottom surface of the tray and receiving and absorbing the urine falling from the hole of the upper container;
The tray has a pair of horizontal walls provided along the horizontal direction while rising upward from the bottom surface on both sides in the vertical direction so as to define a region where the absorbent sheet is placed, and on both sides in the horizontal direction. A pair of vertical walls provided along the vertical direction while rising upward from the bottom surface,
A lateral wall displacement portion in which the lateral wall is displaced outward in the longitudinal direction is formed at the lateral end portion of the lateral wall so as to correspond to at least one corner portion of the four corners of the placement region. The animal toilet is characterized in that a vertical wall displacement portion in which the vertical wall is displaced outward in the horizontal direction is formed at an end of the vertical wall in the vertical direction.

  According to such an animal toilet, for at least one of the four corners of the placement area defined on the tray, the end of the horizontal wall is displaced outward in the vertical direction. It has a horizontal wall displacement portion, and the end of the vertical wall has a vertical wall displacement portion displaced outward in the horizontal direction. Therefore, when the absorbent sheet is placed on the tray, each bending operation applied from both the vertical and horizontal directions to the corner portion of the sheet can be mitigated by the horizontal wall displacement portion and the vertical wall displacement portion. Thus, it is possible to suppress the standing of the corner portion. And as a result, the big protrusion to the upper part of the same corner | angular part can be suppressed.

Such an animal toilet,
The lateral wall displacement portion is displaced outward in the longitudinal direction as it goes outward in the lateral direction,
It is desirable that the vertical wall displacement portion is displaced outward in the lateral direction as it goes outward in the vertical direction.

  According to such an animal toilet, the lateral wall displacement portion is displaced outward in the vertical direction as it goes outward in the horizontal direction, and the vertical wall displacement portion is outward in the lateral direction as it goes outward in the vertical direction. It is displaced. Therefore, each bending operation | movement provided from the vertical and horizontal directions with respect to the corner | angular part of an absorptive sheet can be eased smoothly. As a result, it is possible to smoothly suppress the rising of the corner portion, and as a result, it is possible to quickly suppress a large protrusion upward of the corner portion.

Such an animal toilet,
The joint portion between the horizontal wall displacement portion and the vertical wall displacement portion is located on the outer side in the vertical direction with respect to the portion of the horizontal wall excluding the horizontal wall displacement portion, and the vertical wall among the vertical walls. It is desirable to be located on the outer side in the lateral direction with respect to the portion excluding the wall displacement portion.

  According to such an animal toilet, the effect of suppressing the upward protrusion of the corner can be more reliably achieved.

Such an animal toilet,
The inner wall surface of the horizontal wall is tilted based on the tilt angle for the horizontal wall so that the upper part is positioned outside the vertical direction than the lower part in the vertical direction,
The inner wall surface of the vertical wall is tilted based on the tilt angle for the vertical wall so that the upper part is positioned on the outer side in the horizontal direction than the lower part in the vertical direction,
It is desirable that the maximum value of the falling angle for the inner wall surface of the horizontal wall is smaller than the maximum value of the falling angle for the inner wall surface of the vertical wall.

  According to such an animal toilet, the inner wall surface of the horizontal wall is in a state of standing more than the inner wall surface of the vertical wall. Therefore, the horizontal wall can effectively prevent the absorbent sheet from moving in the vertical direction relative to the tray due to its own inertia or the like when the tray is pulled out or pushed in.

Such an animal toilet,
It is desirable that the tilt angle at the lateral wall displacement portion is equivalent to the tilt angle at the lateral central portion of the lateral wall.

  According to such an animal toilet, since the tilt angle of the inner wall surface at the lateral wall displacement portion is the same as the tilt angle of the inner wall surface at the lateral central portion of the lateral wall, the lateral wall has a lateral end portion. Can also exhibit the effect of suppressing the relative movement of the absorbent sheet equivalent to the central portion. And thereby, it can prevent effectively that an absorptive sheet moves relatively in the direction of the corner of a tray, ie, the direction between the vertical direction and a horizontal direction.

Such an animal toilet,
The tray has a shape that is longer in the vertical direction than in the horizontal direction,
Either of the two sides of the tray in the longitudinal direction can be accommodated in the lower container, even if facing forward.
It is desirable that the horizontal wall displacement portion and the vertical wall displacement portion are provided for all corner portions of the four corners of the placement region.

According to such an animal toilet, it can be accommodated in the lower container from the insertion port regardless of which side of the tray in the vertical direction is directed toward the insertion port of the lower container. Therefore, it is possible to reliably prevent the operator from mistakenly inserting the tray in the wrong direction.
Moreover, since the horizontal wall displacement part and the vertical wall displacement part are provided at all the corners of the four corners of the tray mounting area, they protrude greatly upward from all the corners of the four corners of the absorbent sheet. Can be prevented. As a result, when pulling out the tray from the lower container or pushing the tray into the lower container, it is possible to reliably prevent the four corners from being caught by the lower container. It is possible to reliably prevent the sheet from relatively moving in the vertical direction.

Such an animal toilet,
In the predetermined range including the displacement start position to the outside of the vertical direction of the horizontal wall displacement portion, the horizontal wall is displaced along an arc curve,
It is desirable that the vertical wall is displaced along an arcuate curve within a predetermined range including a position where the vertical wall displacement portion is displaced outward in the lateral direction.

  According to such an animal toilet, the horizontal wall can smoothly move from the horizontal wall displacement portion to the vicinity thereof on the basis of the displacement along the arc curve in each predetermined range, and also in the vertical wall It is possible to smoothly shift from the vertical wall displacement portion to the vicinity thereof. Therefore, the change in the folding state of the absorbent sheet that can occur between the lateral wall displacement portion and the vicinity thereof can be made continuous and gentle, and thereby the inner wall surface of the lateral wall that can occur when the change is large The separation of the absorbent sheet from the inner wall and the separation of the absorbent sheet from the inner wall surface of the vertical wall are suppressed, and as a result, the absorbent sheet is reliably brought into contact with the inner wall surface of the horizontal wall and the inner wall surface of the vertical wall, respectively. be able to.

Such an animal toilet,
The vertical length of the vertical wall is longer than the horizontal length of the horizontal wall,
The absorbent sheet has a longitudinal direction and a width direction shorter in length than the longitudinal direction, and the absorbent sheet has the longitudinal direction along the longitudinal direction and the width direction in the lateral direction. Is placed on the tray along the
It is desirable that the longitudinal length of the vertical wall displacement portion is longer than the lateral length of the lateral wall displacement portion.

  According to such a toilet for animals, the long side part of an absorptive sheet comes to follow a vertical wall longer than a horizontal wall. And in that case, the longer side portion of the absorbent sheet tends to fall more inwardly (in the direction away from the corresponding walls) than the short side portion, but here, The vertical length of the vertical wall displacement portion is increased. Therefore, it is possible to suppress the tendency that the long side portion easily falls inward. And thereby, it is possible to prevent the long side portion, which is longer than the short side portion of the absorbent sheet, from collapsing inward in the lateral direction and overlapping the inner portion of the sheet from above, thereby It can prevent the urine absorbability from having a great adverse effect.

Such an animal toilet,
It is desirable that the joint portion extends along a direction parallel to a direction orthogonal to the plane center position on the bottom surface of the tray.

  According to such an animal toilet, the direction in which the joining portion extends is substantially orthogonal to the direction parallel to the bottom surface of the tray. Therefore, the joint portion can firmly receive the absorbent sheet that relatively moves along the bottom surface toward the corner of the tray, and thereby the relative movement of the absorbent sheet to the corner of the tray. Can be effectively regulated.

Such an animal toilet,
The vertical length of the vertical wall is longer than the horizontal length of the horizontal wall,
The absorbent sheet has a longitudinal direction and a width direction shorter in length than the longitudinal direction, and the absorbent sheet has the longitudinal direction along the longitudinal direction and the width direction in the lateral direction. Is placed on the tray along the
When viewed from above, the bottom surface of the tray has a rectangular area;
The rectangular region is partitioned by both a portion of the horizontal wall excluding the horizontal wall displacement portion and its extrapolation line, and a portion of the vertical wall excluding the vertical wall displacement portion and its extrapolation line. Area,
It is desirable that the joint is located on the vertical wall side with respect to the diagonal line of the rectangular region.

  According to such a toilet for animals, the long side part of an absorptive sheet comes to follow a vertical wall longer than a horizontal wall. And in that case, the long side portion of the absorbent sheet tends to fall inward more easily than the short side portion, but on the other hand, here, the joint portion is on the vertical wall side than the diagonal line. Is located. Therefore, it is possible to suppress the tendency that the long side portion easily falls inward. That is, when the joint portion is located on the side of the horizontal wall from the diagonal line, the long side portion is more likely to fall inward in the horizontal direction than the short side portion is tilted inward in the vertical direction. When the joint portion is located on the vertical wall side from the diagonal line, the short side portion is more likely to fall inward in the vertical direction than the long side portion falls inward in the horizontal direction. Here, the latter positional relationship is adopted here. Therefore, it is possible to prevent the long side portion, which is longer than the short side portion of the absorbent sheet, from collapsing inward in the lateral direction and overlapping the inner portion of the sheet from above. It is possible to prevent a significant adverse effect on absorption.

Such an animal toilet,
When the upper part of the edge located in the lower container is viewed from above among the insertion openings of the lower container, the part corresponding to the corner of the tray in the upper part has a curved part. It is desirable to do.

  According to such an animal toilet, the portion corresponding to the corner of the tray in the upper portion of the edge portion has a curved portion. Therefore, when the tray is pulled out from the lower container, even if the portion hits the corner of the absorbent sheet, the corner hits the corner gradually. And thereby, it is possible to reduce the vertical external force applied to the absorbent sheet from the upper part of the edge of the insertion port via the corner, and as a result, the absorbent sheet is not intended for the tray. The relative movement in the vertical direction can be suppressed.

=== This Embodiment ===
FIG. 3 is a schematic perspective view of the animal toilet 1 of the present embodiment. FIG. 4 is an exploded side view of the animal toilet 1. In the following description, three directions orthogonal to each other are referred to as a vertical direction, a horizontal direction, and a vertical direction. The vertical direction is also referred to as “front-rear direction”, and the horizontal direction is also referred to as “left-right direction”.

  As shown in FIGS. 3 and 4, this animal toilet 1 includes an upper container 10, a lower container 20 disposed below the upper container 10, and a tray 30 accommodated in the lower container 20 so as to be able to be drawn forward. And a cover 40 disposed above the upper container 10. A plurality of through holes h, h... Penetrating in the vertical direction are formed on the bottom surface portion 10t of the upper container 10, and granular materials (not shown) such as cat sand are placed on the bottom surface portion 10t. Is placed.

  Therefore, when an animal such as a cat rides on the granular material on the bottom surface portion 10t of the upper container 10 through the opening 40h for the cover 40 and urinates, the urine is separated from the gap between the granular materials and the through holes h, Through h ..., it falls on the lower tray 30 and is received, whereby the urine is stored in the tray 30. As shown in FIG. 4, the tray 30 is provided with an absorbent sheet 50 that absorbs liquid, for example, in a substantially rectangular shape in plan view, so that the urine can be absorbed and held firmly. It is.

Hereinafter, the upper container 10, the lower container 20, the tray 30, and the absorbent sheet 50 will be described.
5A is a schematic plan view of the animal toilet 1 with the cover 40 removed, FIG. 5B is a schematic central cross-sectional view taken along the line BB in FIG. 5A, and FIG. It is a general | schematic center longitudinal cross-sectional view which is CC sectional drawing in the inside. Moreover, FIG. 6 is a schematic front view as seen in the direction of arrows VI-VI in FIG. 5A.

  The upper container 10 is, for example, a bottomed and uncovered container, and the shape of the bottom surface portion 10t is such that the height of the predetermined area 10tm including the plane center position C10t is low, and the areas 10tf, 10tb, 10ts, 10ts around the four sides. The shape of the mortar is raised. The upper surface of the predetermined region 10tm is formed to be substantially flat, and the plurality of through holes h, h... Are formed in the region 10tm in a vertically long shape. 10 tm is defined as a mesh-like region 10 tm through which urine can pass. Incidentally, in this example, the plane center position C10tm of the mesh-like region 10tm is shifted backward from the plane center position C10t of the bottom surface portion 10t of the upper container 10, and basically this height is low. Although the above-mentioned granular material such as cat sand is dispersed and placed on the mesh-like region 10tm, it is not limited to this.

  The lower container 20 is also a bottomed and uncovered container, for example. That is, the lower container 20 has a front wall 20f, a rear wall 20b, left and right side walls 20s, 20s, and a bottom wall 20t, and these front wall 20f, rear wall 20b, and left and right side walls 20s, 20s is erected upward from the front edge, the rear edge, and the left and right side edges of the bottom wall 20t. However, in this example, from the viewpoint of weight reduction and material cost reduction, the bottom wall 20t is formed with a substantially rectangular large opening 20th in the vertical direction so that the lower container 20 is substantially Although it is a container with no bottom, it is not limited to this.

  Further, as shown in FIGS. 5C and 6, a horizontally long insertion port 20 fh is formed in the front wall 20 f forming the front surface of the lower container 20 so as to penetrate in the front-rear direction. The tray 30 is inserted into the insertion port 20fh from the front, whereby the tray 30 is accommodated in the lower container 20 so as to be drawn forward from the lower container 20.

  Further, the front wall 20f is formed with a recessed surface 20fk that is recessed rearward adjacent to the upper portion of the insertion port 20fh, thereby making it possible to easily grip a grip portion 30fg described later of the tray 30 from above. Yes.

  FIG. 7A is a schematic plan view of the tray 30. FIG. 7B is a schematic cross-sectional view taken along the line BB in FIG. 7A, FIG. 7C is a schematic front view taken along the line CC in FIG. 7A, and FIG. It is a general | schematic center longitudinal cross-sectional view which is DD sectional drawing. FIG. 8 is a schematic perspective view of the tray 30 as seen from the upper surface side.

  As shown in FIGS. 7A to 7D and FIG. 8, the tray 30 is, for example, a flat container having a bottom with no bottom and a shallow bottom. That is, a horizontally long front side wall 30f that extends along the horizontal direction while being positioned on the front side in the vertical direction, and a horizontally long rear side wall 30b that is positioned on the back side and extends along the horizontal direction, A vertically elongated right vertical wall 30s extending along the vertical direction while being positioned on the right side in the horizontal direction, and a vertically elongated left vertical wall 30s extending along the vertical direction while being positioned on the left side in the horizontal direction; A bottom wall 30t having a substantially rectangular shape in plan view that is longer in the vertical direction than in the horizontal direction. The front side wall 30f, the rear side wall 30b, and the left and right vertical walls 30s and 30s are provided upright from the front edge, the rear edge, and the left and right side edges of the bottom wall 30t, respectively. Thus, on the tray 30, a placement area A30 for placing the absorbent sheet 50 is partitioned into a substantially rectangular shape in plan view (see the dot pattern area A30 in FIGS. 8 and 10A). ). That is, the absorbent sheet 50 includes the inner wall surface 30fs of the front side wall 30f, the inner wall surface 30bs of the rear side wall 30b, and the inner wall surfaces 30ss and 30ss of the left and right vertical walls 30s and 30s, and the region A30 on the inner side. Is placed as a placement area A30.

  On the other hand, on the front side wall 30f of the tray 30, a grip portion 30fg that is gripped when the tray 30 is pulled out from the lower container 20 is formed. For example, in this example, as shown in FIG. 7C and FIG. 7D, a recess 30 fk having a substantially rectangular shape in front view that is recessed rearward is formed in the lower portion of the front side wall 30 f, and above the recess 30 fk. The remaining portion 30fg functions as the grip portion 30fg.

As shown in FIG. 7A, the shape of the tray 30 is line-symmetric with respect to the vertical center line CL1 and the horizontal center line CL2. For example, the rear side wall 30b and the front side wall 30f have the same shape in the mirror image relation such that the rear side wall 30b is also provided with a grip part 30bg having the same specifications as the grip part 30fg. In addition, each of the lateral walls 30f and 30b has a symmetrical shape. Further, the left and right vertical walls 30s and 30s have the same shape in mirror image relation with each other, and the vertical walls 30s and 30s are also symmetrical in the front-rear direction.
Therefore, the tray 30 can be replaced in the front-rear direction. That is, the tray 30 can be inserted into the insertion port 20fh of the lower container 20 in FIG. 6 from either the rear side wall 30b or the front side wall 30f. This prevents the operator from mistakenly inserting the tray 30 in the wrong direction.

  However, it is not limited to this. For example, the shape of the tray 30 may not be axisymmetric with respect to the vertical center line CL1 such that the rear side wall 30b does not have the gripping portion 30bg. It does not have to be symmetrical.

FIG. 9A is a schematic plan view of the absorbent sheet 50. 9B is a schematic cross-sectional view taken along the line BB in FIG. 9A, and FIG. 9C is a schematic vertical cross-sectional view taken along the line CC in FIG. 9A.
The absorbent sheet 50 has, for example, a substantially rectangular shape in plan view having a longitudinal direction and a width direction (a direction shorter in length than the longitudinal direction). Further, in the thickness direction orthogonal to the longitudinal direction and the width direction, the absorbent sheet 50 includes a liquid-permeable top sheet 51 and a liquid-impermeable bottom sheet 52 disposed below the top sheet 51. And an absorber 53 that is inserted between the sheets 51 and 52 and absorbs urine. And the plane size of these both sheets 51 and 52 is made larger than the plane size of the absorber 53, and it has a part which protruded from the four sides of the absorber 53 by this, and these protruded parts adhere or Joined by welding or the like. In the following, a portion of both the sheets 51 and 52 that protrudes to the outside of the four sides from the absorber 53, that is, a portion 50f in which the absorber 53 does not exist in the absorbent sheet 50 is referred to as a “flap portion 50f”. Say. Incidentally, the pair of long side portions 50Y and 50Y and the pair of short side portions 50X and 50X forming the four sides of the planar shape of the absorbent sheet 50 all belong to the flap portion 50f.

  As an example of the absorber 53, what shape | molded liquid absorptive materials, such as a pulp fiber and a superabsorbent polymer, in predetermined shapes, such as a planar view rectangular shape, can be mentioned, and the upper surface sheet 51 and the lower surface sheet 52 can be mentioned. As an example, a nonwoven fabric, a resin film, etc. can be mentioned, respectively. However, the present invention is not limited to this, and any material that exhibits the above functions can be used as appropriate.

  FIG. 10A is a schematic plan view of a state in which such an absorbent sheet 50 is placed on the tray 30. 10B is a schematic center cross-sectional view taken along the line BB in FIG. 10A, and FIG. 10C is a schematic center longitudinal cross-sectional view taken along the line CC in FIG. 10A. In these FIGS. 10A to 10C, the absorbent sheet 50 is indicated by a two-dot chain line for the purpose of preventing complication of the drawings.

  As indicated by the two-dot chain line, the planar size of the absorbent sheet 50 is generally the size corresponding to the placement area A30 (dot pattern area) of the tray 30. That is, the size is larger than the substantially flat bottom surface 30ts of the bottom wall 30t of the tray 30, and more specifically, the inner wall surfaces 30ss, 30ss of the pair of vertical walls 30s, 30s and the pair of the pair of vertical walls 30s, 30s. The inner walls 30 fs and 30 bs of the horizontal walls 30 f and 30 b are larger in size. And when mounting in mounting area | region A30, the longitudinal direction of the absorptive sheet 50 is along a vertical direction, and it mounts along the width direction along a horizontal direction.

  Therefore, as shown in FIG. 10B, the pair of long side portions 50Y and 50Y of the absorbent sheet 50 abut on the inner wall surfaces 30ss and 30ss of the pair of vertical walls 30s and 30s of the tray 30 from above, respectively. As shown in FIG. 10C, the pair of short side portions 50X and 50X of the sheet 50 abut on the inner wall surfaces 30fs and 30bs of the pair of lateral walls 30f and 30b of the tray 30 from above. That is, the pair of long side portions 50Y and 50Y and the pair of short side portions 50X and 50X of the absorbent sheet 50 respectively correspond to the inner wall surfaces 30ss and 30ss of the corresponding vertical walls 30s and 30s and the inner wall surfaces 30fs and 30fs of the horizontal walls 30f and 30b, respectively. Get on 30bs. As a result, each of the long side portions 50Y and 50Y and each of the short side portions 50X and 50X are bent upward and are in an upright state.

  However, at this time, the corners 50C, 50C,... At the four corners of the absorbent sheet 50 are respectively bent from both the vertical and horizontal directions, thereby, as shown in FIG. Will protrude greatly upwards. As a result, the problem described at the beginning, that is, “when the tray 30 is pulled out from the lower container 20 or pushed into the lower container 20, the corners 50C, 50C... The sheet 50 may unintentionally move relative to the tray 30 in the vertical direction ”.

  Therefore, in the present embodiment, a predetermined device is applied to the tray 30 in order to suppress the protrusion of the corner portion 50C. Hereinafter, this device will be described. In the example of FIG. 10A, this device is applied to all corners A30C, A30C,... Of the above-described placement area A30 on the tray 30, and both have the same configuration. It is. Therefore, hereinafter, one of the corners A30C will be described. Here, the corner A30C used for the description is a corner A30C formed by connecting the rear lateral wall 30b and the left vertical wall 30s (the upper left corner A30C in FIG. 10A). Hereinafter, the long side portion 50Y of the absorbent sheet 50 is also referred to as a “longitudinal side portion 50Y”, and the short side portion 50X is also referred to as a “lateral side portion 50X”.

  FIG. 11A is a schematic enlarged view of the Xa portion in FIG. 10A showing the corner portion A30C in an enlarged manner. 11B is a cross-sectional view taken along the line BB in FIG. 11A, and FIG. 11C is a cross-sectional view taken along the line CC in FIG. 11A. Further, FIG. 12 is a schematic perspective view of a portion Xa in FIG. 10A.

  As shown in FIG. 11A and FIG. 12, first, the lateral wall displacement portion in which the lateral wall 30b is displaced outward in the longitudinal direction at the lateral end portion of the lateral wall 30b in correspondence with the corner portion A30C of the placement region A30. 30bD is formed, and a vertical wall displacement portion 30sD in which the vertical wall 30s is displaced outward in the horizontal direction is formed at the vertical end of the vertical wall 30s. As a result, in the corner portion A30C of the placement area A30, the bottom surface 30ts of the bottom wall 30t expands outward in the vertical direction and outward in the horizontal direction, respectively.

  Therefore, each bending operation given from both the vertical and horizontal directions to the corner portion 50C of the absorbent sheet 50 can be relaxed based on the horizontal wall displacement portion 30bD and the vertical wall displacement portion 30sD, thereby absorbing. The standing of the corner portion 50C of the adhesive sheet 50 can be suppressed. As a result, large upward protrusion of the same corner portion 50C can be suppressed.

  Further, in this example, as shown in FIG. 11A, the horizontal wall displacement portion 30bD is gradually displaced outward in the vertical direction toward the outer side in the horizontal direction. Similarly, the vertical wall displacement portion 30sD is It is gradually displaced outward in the horizontal direction as it goes outward in the vertical direction.

  Therefore, each bending operation given to the corner portion 50C of the absorbent sheet 50 from both the vertical and horizontal directions can be smoothly relaxed based on the gentle displacement as described above. As a result, the rising of the corner 50C can be smoothly suppressed, and as a result, a large protrusion upward of the corner 50C can be quickly suppressed.

  Furthermore, in this example, the joint portion 30j between the horizontal wall displacement portion 30bD and the vertical wall displacement portion 30sD is located on the outer side in the vertical direction from the portion 30bN of the horizontal wall 30b excluding the horizontal wall displacement portion 30bD. Of the vertical wall 30s, it is located on the outer side in the horizontal direction with respect to the portion 30sN excluding the vertical wall displacement portion 30sD. Therefore, the effect of suppressing the upward protrusion of the corner portion 50C can be more reliably achieved.

  As described above, in this example, the horizontal wall displacement portion 30bD and the vertical wall displacement portion 30sD are provided for all of the corners A30C, A30C,... Of the four corners of the placement region A30. Not exclusively. That is, if it provides with respect to at least 1 corner | angular part A30C, about the corner | angular part A30C, the protrusion of the corner | angular part 50C of the absorbent sheet 50 can be suppressed, and the corner | angular part 50C Through suppression of catching on the insertion port 20fh or the like, unintended vertical relative movement of the absorbent sheet 50 can be suppressed. Therefore, it is only necessary to provide the horizontal wall displacement portion 30bD and the vertical wall displacement portion 30sD with respect to at least one corner A30C. However, it goes without saying that it is preferable to provide a plurality of corners A30C, A30C... Rather than one corner A30C.

  Further, in this example, as shown in FIG. 11A, in the predetermined range including the displacement start position P2 to the outside in the vertical direction of the lateral wall displacement portion 30bD, the lateral wall displacement portion 30bD is displaced along the arc curve. Further, the vertical wall displacement portion 30sD is displaced along an arcuate curve within a predetermined range including the lateral displacement start position P1 of the vertical wall displacement portion 30sD in the lateral direction.

  Therefore, the change of the folding state of the absorbent sheet 50 that can occur between the lateral wall displacement portion 30bD and the vicinity thereof can be made continuous and gentle, and thereby the lateral wall 30b that can occur when the change is large. The separation of the lateral side portion 50X of the absorbent sheet 50 from the inner wall surface 30bs and the separation of the longitudinal side portion 50Y of the absorbent sheet 50 from the inner wall surface 30ss of the vertical wall 30s can be suppressed, and as a result, these lateral sides The portion 50X and the vertical side portion 50Y can be reliably brought into contact with the inner wall surface 30bs of the horizontal wall 30b and the inner wall surface 30ss of the vertical wall 30s, respectively.

  The lateral length L30bD of the lateral wall displacement portion 30bD is selected from, for example, a range of 5 mm to 40 mm, and the maximum displacement amount of the displacement portion 30bD is within a range of, for example, 2 mm to 20 mm. Set to Similarly, the length L30sD in the vertical direction of the vertical wall displacement portion 30sD is selected from a range of 10 mm to 60 mm, for example, and the maximum amount of the horizontal displacement of the displacement portion 30sD is in a range of 5 mm to 30 mm, for example. Set to fit. And if it sets in this way, it will come out more reliably with the suppression effect of the above-mentioned protrusion of the corner | angular part 50C.

  In this example, since the longitudinal direction of the absorbent sheet 50 is arranged along the vertical direction as described above, the vertical length of the vertical wall 30s is larger than the horizontal length of the horizontal wall 30b. In such a case, as shown in FIG. 11A, the vertical length L30sD of the vertical wall displacement portion 30sD is greater than the horizontal length L30bD of the horizontal wall displacement portion 30bD. It is better to make it longer, in this example it is.

  And if it does in this way, it will become possible to suppress the tendency that the vertical side part 50Y of the absorptive sheet 50 falls down easily inside. That is, in the example of FIG. 11A, since the vertical length of the vertical wall 30s is long, the vertical side portion 50Y of the absorbent sheet 50 is on the inner side (from the corresponding walls 30b and 30s) compared to the horizontal side portion 50X. However, here, the vertical length L30sD of the vertical wall displacement portion 30sD is made longer than the horizontal length L30bD of the horizontal wall displacement portion 30bD. . Therefore, based on the long vertical wall displacement portion 30sD, it is possible to suppress the tendency that the vertical side portion 50Y easily falls inward, and thereby, the vertical side longer than the horizontal side portion 50X of the absorbent sheet 50. The side portion 50Y can be prevented from falling to the inside in the lateral direction and overlapping the inner portion of the sheet 50 from above. Thereby, it is possible to prevent the urine absorbability from being adversely affected.

  Further, in this example, when the tray 30 is viewed from above as in the schematic plan view of FIG. 13, the bottom surface 30ts of the bottom wall 30t of the tray 30 has a rectangular region A30a. That is, as shown by a dot pattern in FIG. 13, the rectangular area A30a includes a portion 30bN (30fN) of the horizontal wall 30b (30f) excluding the horizontal wall displacement portion 30bD (30fD) and its extrapolation line L30bN (L30fN). ) And a portion 30sN of each vertical wall 30s excluding the vertical wall displacement portion 30sD and its extrapolation line L30sN. Here, the joint portion 30j is formed of the rectangular region A30a. It is located closer to the vertical wall 30s than the diagonal line LCA30a.

  And according to this positional relationship, it can prevent more effectively that the above-mentioned vertical side part 50Y falls down inside. That is, when the joint portion 30j is positioned on the side of the horizontal wall 30b (30f) with respect to the diagonal line LCA30a, the vertical side portion 50Y is inward in the horizontal direction rather than the horizontal side portion 50X is tilted inward in the vertical direction. Conversely, when the joint portion 30j is positioned on the vertical wall 30s side with respect to the diagonal line LCA 30a, the horizontal side portion 50X rather than the vertical side portion 50Y falling inward in the horizontal direction. However, in this example, the latter positional relationship is adopted. Therefore, it is possible to prevent the longitudinal side portion 50Y, which is longer than the lateral side portion 50X of the absorbent sheet 50, from collapsing inward in the lateral direction and overlapping the inner portion of the sheet 50 from above. Thus, it is possible to more effectively prevent the urine absorbability from having a great adverse effect.

Further, in this example, as shown in FIG. 11B, the inner wall surface 30bs of the horizontal wall 30b is based on the tilt angle θ30bs for the horizontal wall 30b so that the upper part is positioned on the outer side in the vertical direction rather than the lower part in the vertical direction. Similarly, as shown in FIG. 11C, the inner wall surface 30ss of the vertical wall 30s is also tilted for the vertical wall 30s so that the upper part is positioned on the outer side in the horizontal direction rather than the lower part in the vertical direction. Has fallen on the basis of. The maximum value of the fall angle θ30bs for the former horizontal wall 30b is smaller than the maximum value of the fall angle θ30ss for the latter vertical wall 30s. That is, the inner wall surface 30bs of the horizontal wall 30b is in an upright state as a whole than the inner wall surface 30ss of the vertical wall 30s.
Therefore, the horizontal wall 30b effectively prevents the absorbent sheet 50 from moving relative to the tray 30 in the vertical direction due to its own inertia or the like when the tray 30 is pulled out or pushed in. Can do.

  From the viewpoint of enhancing this effect, it is desirable that the average value of the tilt angle θ30bs for the horizontal wall 30b is smaller than the average value of the tilt angle θ30ss for the vertical wall 30s. Further, the tilt angle θ30bs for the horizontal wall 30b is set to fall within a range of 0 ° to 5 °, for example, and the tilt angle θ30ss for the vertical wall 30s is set to fall within a range of 2 ° to 40 °, for example. Good.

  Furthermore, in the example of FIG. 13, the tilt angle θ30bs of the inner wall surface 30bs at the lateral wall displacement portion 30bD is the same value as the tilt angle θ30bs of the inner wall surface 30bs at the lateral central portion 30bC of the lateral wall 30b.

  And if it becomes like this, the horizontal wall 30b can show | play the inhibitory effect of the relative movement of the absorbent sheet 50 equivalent to the center part 30bC also in the edge part of a horizontal direction. And thereby, it can prevent effectively that the absorptive sheet 50 moves relatively in the direction of corner | angular part A30C of mounting area | region A30, ie, the direction between a vertical direction and a horizontal direction.

  In addition, from the viewpoint of suppressing the relative movement of the absorbent sheet 50 in the direction of the corner portion A30C, preferably, the joint portion 30j between the horizontal wall displacement portion 30bD and the vertical wall displacement portion 30sD is the bottom wall 30t of the tray 30. It is preferable to extend along a direction parallel to a direction orthogonal to the plane center position C30ts on the bottom surface 30ts. That is, if it becomes like this, since the direction where the joint part 30j extends is substantially orthogonal to the direction parallel to the bottom face 30ts of the bottom wall 30t, the joint part 30j is directed to the corner A30C. And the absorptive sheet | seat 50 which moves relatively along the said bottom face 30ts can be received firmly. As a result, relative movement to the corner A30C can be reliably regulated.

FIG. 14 is a schematic plan view of the lower container 20 in which the tray 30 is accommodated. In FIG. 14, the lower container 20 is shown with a dot pattern. In this example, when the upper part 20fhebu of the edge part 20fheb located in the lower container 20 in the insertion opening 20fh provided in the lower container 20 is viewed from above, the upper part 20fhebu has the above-mentioned corner part A30C of the tray 30. Corresponding portion 20fheup has an arc-curved portion as an example of a curvilinear shape.
Therefore, when the tray 30 is pulled out from the lower container 20, even if the portion 20fheup related to the edge portion 20fheb hits the corner portion 50C of the absorbent sheet 50, it takes time for the corner portion 50C little by little. It becomes like this. As a result, it is possible to reduce the vertical external force applied to the absorbent sheet 50 from the upper portion 20fhebu of the edge portion 20fheb of the insertion port 20fh via the corner portion 50C, and as a result, against the tray 30. Unintended vertical relative movement of the absorbent sheet 50 can be suppressed.

  By the way, examples of the material of the upper container 10, the lower container 20, the tray 30, and the cover 40 include polyolefin-based thermoplastic resins such as polyethylene, polypropylene, and polyethylene terephthalate, but are not limited thereto. For example, a resin other than these may be used, or a metal plate such as a stainless steel plate or an aluminum plate may be used.
