Here, in the container 10 of the present embodiment, a communication hole 35 is formed at a corner portion of the lower end portion for communicating the inside and outside of the container 10 . As shown in FIG. 5, the communication hole 35 is formed through the bottom wall 11 and the outer peripheral wall 15, and is a bottom wall opening formed by notching the corners of the bottom wall 11 in a substantially right-angled isosceles triangle shape in plan view. 36 , and a side wall opening 37 formed by notching the lower end corner of the outer peripheral wall 15 continuously with the bottom wall opening 36 . The lower edge of the side wall opening 37 is the same as the two orthogonal sides (including the corner portion between the two sides) of the bottom wall opening 36, and the upper edge of the side wall opening 37 is the same length and parallel to the lower edge. extends to Both side edges of the side wall opening 37 extend vertically to connect the upper edge and the lower edge of the side wall opening 37 .

As shown in FIG. 6, the communication hole 35 has a size obtained by notching between the two corner horizontal vertical ribs 26 . In addition, a portion corresponding to the communication hole 35 in the lower end flange portion 31 is notched, and between the two corner horizontal vertical ribs 26, a corner horizontal rib projecting outward from the upper edge of the side wall opening 37 is provided. 27 is provided. The tip surface of the corner lateral rib 27 is flush with the tip surfaces of the vertical ribs 25 and 26 . The lower surface of the corner horizontal rib 27 and the portion below the corner horizontal rib 27 of the side surfaces of the two corner horizontal vertical ribs 26 on the corner center vertical rib 25 side are referred to as an "extending portion 28". A portion of the extending portion 28 below the upper surface of the bottom wall 11 is referred to as a lower extending portion 28K. The lower extension portion 28K extends to a position where it abuts on the upper end flange portion 21 of the lower container 10 when the containers 10 are stacked.

The lower end outer peripheral wall 13 of the fitting protrusion 12 is arranged on four sides of the bottom wall 11, and includes protrusion side portions 13A extending along the lower outer peripheral wall 15 in a stacked state, and communication holes 35 in the bottom wall 11. and a protrusion connecting portion 13B that hangs down from the opening edge (the oblique side portion of the isosceles right triangle of the bottom wall opening portion 36). The protrusion connecting portion 13B connects the ends of the adjacent protrusion side portions 13A. In addition, the end surface of the opening edge of the communication hole 35 in the bottom wall 11 and the protrusion connecting portion 13B are flush with each other. Furthermore, the end surface of the opening edge of the communication hole 35 in the bottom wall 11 and the lower end of the side surface of the corner central vertical rib 25 of the corner horizontal vertical rib 26 are continuous in a bent state.

As shown in FIG. 4, when the containers 10 are stacked, the upper surface of the bottom wall 11 of the upper container 10 is located one plate thickness above the upper surface of the upper end flange portion 21 of the lower container 10. , the communication hole 35 of the upper container 10 is not blocked by the outer peripheral wall 15 of the lower container 10 in the horizontal direction. As shown in FIG. 7, even when the containers 10 are stacked with the openings 10A facing downward, the upper end flange 21 of the upper container 10 abuts the lower end flange 31 of the lower container 10. 10 communication holes 35 are not blocked by the outer peripheral wall 15 of the upper container 10 in the horizontal direction.

The description about the structure of the container 10 of this embodiment is above. Next, the effect of the container 10 of this embodiment is demonstrated. The container 10 of the present embodiment can be stacked and used while containing contents.

By the way, after the container 10 has been used several times, the container 10 is cleaned. The container 10 after washing is applied to a rotary dehydrator. Then, part of the moisture in the container 10 scatters on the inner surface of the outer peripheral wall 15 and is guided along the inner surface by the inclination of the outer peripheral wall 15 to the opening 10A and discharged. Another part moves outward on the bottom wall 11 and is discharged from the communication hole 35 . This facilitates draining of the container 10 compared to a container without the communication holes 35 . Moreover, in the container 10 of the present embodiment, the communication hole 35 is formed across the outer peripheral wall 15 and the bottom wall 11, so that the opening of the communication hole 35 becomes large, and water is easily discharged.

Here, if there are a plurality of containers 10 after washing, the plurality of containers 10 are stacked and applied to the rotary dehydrator. At this time, if the inner space of the lower container 10 is completely closed, it may be difficult to discharge the moisture remaining in the inner space of the lower container 10 to the outside. On the other hand, since the communication hole 35 is arranged in the container 10 of the present embodiment at a position where it is not blocked in the stacking state as described above, the moisture flowing along the inner surface of the outer peripheral wall 15 of the lower container 10 is prevented. is discharged from between the opening 10A and the communication hole 35 of the container 10 on the upper side. Also, the water on the bottom wall 11 of the container 10 is discharged from the communication hole 35, but at this time, the upper surface of the bottom wall 11 of the upper container 10 (the lower edge of the communication hole 35) Since it is located above the upper surface of the upper end flange portion 21, the water discharged from the communication hole 35 is easily discharged to the outside without falling into the lower container 10 (see FIG. 8).

Also, the plurality of containers 10 may be immersed in the cleaning liquid in a stacked state. In this case, in the container 10 of this embodiment, since the upper and lower containers 10 communicate with each other through the communication holes 35, the cleaning liquid spreads over the containers 10 in the lower layer and the intermediate layer. When the group of stacked containers 10 is pulled up from the cleaning liquid, the cleaning liquid is easily discharged because the containers 10 are communicated vertically through the communication holes 35 . At this time, the stacked state is stabilized because the moisture is discharged in order from the container 10 in the upper stage.

Moreover, since the extension 28 is provided at the opening edge of the communication hole 35, the water discharged from the communication hole 35 is smoothly guided outward along the extension (see FIG. 9). Moreover, in this embodiment, since the extending portion 28 extends outward from the outer surface of the outer peripheral wall 15 and extends to the outer end of the container 10 , centrifugally dehydrated water adheres to the outer surface of the outer peripheral wall 15 of the container 10 . difficult to do. In addition, since the protrusion connecting portion 13B of the fitting protrusion 12 hangs down from the opening edge (oblique side portion) of the communicating hole 35 in the bottom wall 11, the opening edge of the communicating hole 35 is strengthened, and the vicinity of the communicating hole 35 is strengthened. less likely to break. Furthermore, since the bottom wall opening 36 of the communicating hole 35 is triangular in plan view, and the projecting portion connecting portion 13B connects the ends of the adjacent projecting portion side portions 13A at the shortest distance, the reinforcing effect is enhanced. Further, since the lower extension portion 28K and the projecting portion connecting portion 13B are continuous, the strength of the opening edge of the communication hole 35 is further increased.

Further, even when the containers 10 are stacked with the openings 10A facing downward, the communication holes 35 of the lower containers 10 are not blocked by the outer peripheral wall 15 of the upper containers 10 in the horizontal direction. Even if it is put in a rotary dewatering machine in a state of being stacked in a row, water can be discharged from the communication hole 35 (see FIG. 7). It should be noted that, if the opening is directed downward, there is a concern that water will accumulate between the lower end outer peripheral wall 13 of the fitting projection 12 and the lattice ribs 14, but it is thought that the water will move outward due to centrifugal force and be discharged. be done. If the connecting portion between the lower surface of the bottom wall 11 and the lower end outer peripheral wall 13 or the lattice rib 14 is formed in an R shape, the moisture can be more easily discharged.

That is, the containers 10 can be centrifugally dehydrated both in a state in which the openings 10A face upward and in a state in which the openings 10A face downward. In addition, the operation of stacking the containers 10 with the openings 10A facing downward may be performed by stacking the containers 10 with the openings 10A facing downward, or by turning over the stacked containers 10 with the openings 10A facing upward. good. Similarly, the operation of stacking the containers 10 with the openings 10A facing upward may be performed by stacking the containers 10 with the openings 10A facing upward, or by turning over the containers 10 stacked with the openings 10A facing downward. good too.
