[Technical field to which the invention belongs]

 The present invention relates to a storage container including a container body and a lid.

[0002]

[Prior art]

 There are various storage containers including a container body and a lid. Such a storage container may be used by stacking it in two or three stages. In this case, the upper storage container is stacked on the lid of the lower storage container. In such a case, the upper storage container slipped off the lower storage container, and the load applied to the lid of the lower storage container was a problem. Although not shown, various measures have conventionally been taken to solve such a problem.

[0003]

[Problems to be solved by the device]

 The present invention has also been made to solve the above problems, and an object thereof is to provide a storage container having sufficient rigidity that does not slide down even when the storage containers are stacked.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the storage container according to the first invention is a rectangular box-shaped container body whose upper surface is opened and whose bottom surface is narrower than the opening, and which is narrowed downward. A storage container comprising a rectangular box-shaped lid body that closes an opening, has a lower surface that is narrower, and has an upper surface that is narrower than the opening. The lid body has an outer periphery at the periphery of the upper surface of the lid body. A ridge that continuously extends from the side of the body and secures a dimension for receiving the bottom surface of the container main body on the inner periphery and bulges upward in a lateral U-shaped cross section except at four corner positions. It is characterized by being formed.

According to the above configuration, since the bottom surface of the container body can be received on the top surface of the lid body surrounded by the raised portion, it is possible to stack another storage container having the same structure on the storage container. In addition, the rigidity of the lid is ensured by the raised portion having a U-shaped cross section. Also, since the raised portions are raised except for the four corner positions of the lid, even if rainwater or dust collects on the top surface of the lid, they will be removed through these four corner positions. can do.

A storage container according to a second aspect of the present invention is the storage container of the above configuration, wherein a rib extending from the back side of the upper surface to the back side of the side surface of the lid is provided at four positions on the back side corners of the top surface of the lid. Is formed.

According to the upper structure, the rigidity of this portion can be increased. Then, when the lids having the same structure are overlapped with each other, this rib comes into contact with the upper surface of the lower lid, so that so-called biting can be prevented.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described.

FIG. 1 is a front view showing a storage container 1 of the present embodiment, and FIGS. 2 to 4 are a plan view, a right side view and a bottom view, respectively. 5 is a sectional view taken along the line AA of FIG. 1, and FIG. 6 is a sectional view taken along the line BB of FIG. The storage container 1 has a rectangular box-shaped container body 2 having an upper surface opened and a bottom surface narrower than the opening, and an opening of the container body 2 closed, and a lower surface opened and a rectangular shape having an upper surface narrower than this opening. It is roughly configured by a box-shaped lid body 3 and a buckle 4 that holds the connection between the container body 2 and the lid body 3.

As shown in FIG. 7, the container body 2 is integrally molded entirely of plastic, has an opening 5 on the upper surface, and has a bottom surface 6 narrower than the opening 5 on four sides. It is formed in a rectangular box shape having four surrounding side surfaces 7.

An opening flange 8 having a shape that is bent outward and further bent downward is formed on the peripheral edge of the opening 5. Opposing central portions of the opening flange 8 are recessed inward, and an engaging portion 11 with which the engaging piece 4a of the buckle 4 engages is formed in this portion. A recess 10 is formed at the center of each side surface 7 and is recessed inward. Further, the bottom surface 6 is formed with ribs 12 projecting downward from the bottom surface in a lattice pattern. The rigidity of the container main body 2 is enhanced by the opening flange recess 8, the recess 10, and the rib 12.

Next, as shown in FIGS. 8 and 9, the lid body 3 is integrally formed of plastic as a whole, and has an opening 21 on the lower surface. It is formed in a rectangular box shape having four side surfaces 23 surrounding four sides of the narrow upper surface 22.

The periphery of the opening 21 has a shape that is bent outward and further bent downward, and when the opening 5 of the container body 2 is closed, the opening flange 5 is removed. A surrounding opening flange 29 is formed. A buckle receiving portion 24, which is recessed inward, is formed in a central portion of the opening flange 29 facing each other, and the buckle receiving portion 24 has a hole (not shown) for pivotally supporting the pivot shaft 4b of the buckle 4. No) is formed.

On the upper surface 22 of the lid body 3, four bulging portions 26 bulging upward in a rectangular shape are formed. Then, in the peripheral portion of the upper surface 22 except for the four corner positions 27, the upper surface 22 extends higher than the upper surface, extends continuously from each side surface 23, is bent inward, and is further bent downward. A ridge 25 having a U-shaped cross section is formed so as to be bent toward the side. The dimension of the upper surface surrounded by each raised portion 25 is set to be larger than the area of the bottom surface 6 of the container body 2.

On the back side of the lid body 3, positioning ribs 30 projecting downward are formed at a total of eight positions at the boundary between the opening flange 29 and each side surface 23 side. Then, on the back side of the four corners 27, as shown in FIG. 10, there are formed ribs 28 extending from the back side of the upper surface 22 to the back sides of the side surfaces 23 by a predetermined length.

As shown in FIG. 11, the storage container 1 configured in this manner firmly holds the coupling between the container body 2 and the lid body 3 with the buckle 4. Then, by rotating the buckle 4 about the pivot shaft 4b of the buckle 4 to release the engagement between the engagement piece 4a and the engagement portion 11, the lid body 3 can be removed from the container body 2. it can .

Further, the storage containers 1 can be stacked as shown in FIG. At this time, the container main body 2 of the upper storage container 1 is placed on the lid 3 of the lower storage container 1. Since the bottom surface 6 of the container body 2 of the upper storage container 1 is received in the upper surface 22 surrounded by the raised portion 25 of the lid 3 of the lower storage container 1, the upper storage container 1 is It is prevented from sliding down from the lower storage container 1. Since the raised portion 25 has a lateral U-shaped cross section, it has a structure that enhances the rigidity of the lid body 3 and can sufficiently withstand the load of the stacked storage containers 1. That is why. Further, since the raised portion 25 is raised except for the four corners 27 of the top surface 22 of the lid 3, the four corners are used to collect, for example, rainwater or dust collected on the top 22. Can be excluded.

Further, since ribs 28 are formed at four corner positions on the back side of the lid body 3, the rigidity of this portion is enhanced, and as shown in FIGS. When the bodies 3 are stacked, the ribs 28 of the upper lid 3 come into contact with the upper surface 22 of the lower lid 3 to prevent so-called biting between the lids 3.

[0019]

[Effect of the invention]

 As described in detail above, according to the present invention, the following effects can be obtained.

The ridge formed on the lid can prevent the upper storage container from slipping down from the lower storage container when accommodating storage containers of the same structure are stacked, and the ridge is formed. Since the rigidity of the lid is increased, it can be used with confidence. Moreover, rainwater and dust collected on the top surface of the lid can be removed through the four corner positions, which is very convenient.

The rigidity of this portion is enhanced by the ribs 28 at four corners on the back side of the lid, and when the lids are stacked, the upper lid of the upper lid is attached to the upper surface of the lower lid. Since the ribs come into contact with each other to prevent so-called biting between the lids, it is very resistant to corner drops, and can contribute to, for example, a reduction in packaging capacity during transportation and an occupied area in the sales floor.
