Then, when the container is placed on a horizontal surface, the mesh-like bottom surface is in close contact with the horizontal surface. Further, the upper surface of the flange portion 6 formed on the outer peripheral portion of the bottom surface is a flat surface, and the upper surface of the handle 14 is also a flat surface.

[0004]

[Problems to be solved by the device]

 The conventional container as described above has a drawback that foreign substances, dust and the like are easily accumulated on the upper surface of the flange portion 6 and the upper surface of the handle 14 while the container is used for a long period of time. Further, when the container is placed on the floor or the like, foreign matter may be attached to the bottom surface of the container.

The above-mentioned foreign matter deposited or adhered to the container is likely to adhere to the clean parts placed in the container, and in such a case, the function originally possessed by the parts may be deteriorated. .

The present invention has been made under the background as described above, and it is an object of the present invention to provide a shape of a container in which foreign matter and the like are less likely to be deposited and adhered.

[0007]

[Means for Solving the Problems]

 According to this invention, flanges are formed on the outer circumferences of the top and bottom surfaces of a box-shaped member having an open top surface, and a plurality of pillars that connect these flanges in the vertical direction are formed, and are arranged opposite to each other. In a plastic container having a handle formed on the outer peripheral portions of two side surfaces, the flange portion formed on the outer peripheral portion of the bottom surface is tapered so that the diameter gradually increases from the upper side to the lower side. The handle is formed so that the outer peripheral surface of the handle is an inclined surface that gradually protrudes toward the outer peripheral side from the upper side toward the lower side. Further, the contour of the flange portion formed on the outer peripheral portion of the bottom surface is formed larger than the contour of the flange portion formed on the outer peripheral portion of the upper surface, and the inner portion of the bottom surface is a space portion, and It is desirable to form a protrusion in which the outer peripheral portion fits into the opening on the upper surface in this space.

[0008]

[Action]

 In the container having the above configuration, the flange portion formed on the outer peripheral portion of the bottom surface is formed in a tapered shape in which the diameter gradually increases toward the outer peripheral side from the upper side to the lower side, and the outer peripheral surface of the handle is changed from the upper side to the lower side. Since it is an inclined surface that gradually protrudes toward the outer peripheral side as it goes toward, it is easy for foreign matter, dust, etc. floating around the container to fall downward, and the upper surface of the flange formed on the outer peripheral part of the bottom surface It is hard for foreign matter and dust to accumulate.

Further, the contour of the flange portion formed on the outer peripheral portion of the bottom surface is formed larger than the contour of the flange portion formed on the outer peripheral portion of the upper surface, and the inner portion of the bottom surface serves as a space portion, and By forming a protrusion in which the outer peripheral portion fits into the opening on the upper surface in this space, the ground contact area on the bottom surface of the container is reduced, and adhesion of foreign matter and the like to the bottom surface of the container is suppressed. By stacking the containers so that the protrusions fit into the openings on the upper surface of another container, the container is stably supported.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Like the container shown in the above-mentioned conventional example, the container according to the present embodiment also has flange portions 20 and 22 formed on the outer peripheral portions of the top and bottom surfaces of the box-shaped member 18 having an open top surface. A plurality of pillars 24 that vertically connect the flanges 20 and 22 are formed in the circumferential direction of the portions 20 and 22, and a handle 30 is provided on the outer peripheral portions of the two side surfaces 26 and 28 that are arranged to face each other. 30 is formed and configured.

However, the handle 30, the flange portion 22 formed on the outer periphery of the bottom surface, and the manner of forming the bottom surface differ from the conventional example in the following points.

First, as shown in FIG. 1, the outer peripheral surface (upper surface) 30a of the handle 30 is formed as an inclined surface that gradually protrudes toward the outer peripheral side from the upper side to the lower side.

Next, as shown in FIG. 1, the flange portion 22 is formed in a tapered shape whose diameter gradually increases toward the outer peripheral side from the upper side to the lower side. Further, the contour of the flange portion 22 is formed to be larger than the contour of the flange portion 20. Therefore, the pillar portions 24 ... Are also formed so as to gradually project in the outer peripheral direction from the upper side to the lower side. .

As for the bottom surface, as shown in FIG. 2, an inner portion of the bottom surface is shaved to form a space portion 32, and a projection portion 34 having a substantially rectangular shape in plan view is provided so as to project from the space portion 32. The space 32 is divided into an inner space 36 and an outer space 38. The contour of the outer periphery of the space portion 32 is formed to be the same as the contour of the outer periphery of the flange portion 20, and the contour of the outer periphery of the protruding portion 34 is formed to be the same as the contour of the opening 40 formed on the upper surface of the container. Further, the height of the projection 34 is formed slightly lower than the height of the flange 22, and when this container is placed on the floor, only the outer peripheral portion of the flange 22 contacts the floor, and the projection 34 is grounded. It is supposed not to.

In the container having the above structure, the outer peripheral surface 30a of the handle 30 is formed into an inclined surface as described above, and the flange portion 22 is also formed into a tapered shape as described above. It becomes difficult for foreign matter, dust, and the like to accumulate on the upper surface and the upper surface of the flange portion 22, so that it is possible to prevent the functional deterioration of the clean parts placed in the container. Further, since the space portion 32 is formed on the bottom surface, it is difficult for foreign matter to adhere to the bottom surface of the container. Furthermore, by fitting the outer peripheral portion of the protrusion 34 into the opening 40 on the upper surface of another container and stacking the containers (see FIG. 3), the containers can be stably supported, and the cleaning parts Transport and storage can be performed stably.

[0016]

[Effect of the device]

 As described above, according to the present invention, the flange portion formed on the outer peripheral portion of the bottom surface is formed in a tapered shape in which the diameter gradually increases toward the outer peripheral side from the upper side to the lower side, and the outer peripheral surface of the handle is raised. Since it is an inclined surface that gradually protrudes toward the outer peripheral side as it goes downward from the above, foreign matter, dust, etc. are less likely to accumulate on the upper surface of the flange portion formed on the outer peripheral portion of the bottom surface and the upper surface of the handle. It is possible to prevent the functional deterioration of the clean parts placed in the container. Further, the contour of the flange portion formed on the outer peripheral portion of the bottom surface is formed to be larger than the contour of the flange portion formed on the outer peripheral portion of the upper surface, and the inner portion of the bottom surface serves as a space portion, and this space portion By forming a protrusion on the outer peripheral part that fits into the opening on the upper surface, it is possible to suppress the adhesion of foreign matter and the like to the bottom surface of the container, and to stabilize this bottom surface on another container. They can be stacked and the clean parts can be transported and stored stably.
