Description

  The present invention relates to a folding container, and more particularly, to a folding container having a frame at the top, which is suitable for accommodating a rounded article.

  In the folding container, as shown in FIG. 2, an upper plate 4 and a lower plate that can be folded inward via a hinge 7 between a rectangular frame 1 and a flat bottom plate 2. There is provided a folding container 20 in which a pair of side plates 8 comprising a portion 6 and closing a side portion, and a pair of flange plates 10 having an upper end swingably supported on the frame 1 and closing an end portion are provided. (For example, patent document 1).

  Thus, when folding the folding container 20 provided with the rectangular frame 1 at the top, first, the lower ends of the turn plates 10 and 10 are flipped up to the opening side of the frame 1 and the hinge 7 is provided. By pushing down the side plate 8 from the outside to the inside, the upper plate portion 4 and the lower plate portion 6 are overlapped to be in a short state.

  Thus, in the folding container 20 provided with the frame 1 at the top, the strength as a container is exerted to the maximum when the pair of crooked plates 10 are erected vertically with respect to the bottom plate 2.

  By the way, in the folding container 20 provided with the frame 1 in the upper portion as described above, for example, when round vegetables such as cabbage are accommodated, the peripheral surface of the article comes into contact with the inner wall surface of the container 20 and is damaged. There was a problem of speeding up, causing loss or damage.

On the other hand, among the folding containers, there is a folding container that can be folded so that a side wall disposed so as to surround the bottom overlaps the bottom. Some of such folding containers are provided with spherical concave portions on the inner wall surface. (For example, patent document 2).

  However, as in Patent Document 1, a pair of upper and lower frames 1 and 2 are attached to the frame 1 and the bottom plate 2 so as to be rotatable with respect to the frame 1 and the bottom plate 2 and are connected to be bent inward at a connecting portion. In the folding container 20 constituted by the side plate 8 and the turn plate 10 attached to the frame 1 so as to be rotatable, no contrivance has been made to the shape of the inner wall surface.

  Moreover, in the folding container 20 like patent document 1, when the load was applied from the upper part, the cover board 10 removed from the baseplate 2 carelessly, and the problem which destroys the contents also occurred.

  In view of such conventional problems, the present invention is particularly a folding container having a rectangular frame at the top, which can be preferably used for accommodating rounded articles, and is loaded from above. It is an object of the present invention to provide a folding container that can effectively prevent disengagement of the twisting plate, such as when it is broken.

In order to achieve the above object, a folding container according to the present invention is arranged between a substantially rectangular frame and a substantially rectangular bottom plate, and can be folded inward via a hinge, and an upper plate portion and a lower plate portion. In a folding container comprising a side plate composed of: and a closing plate whose upper end is swingably supported on the frame so as to close the end.
It is characterized in that the inner wall surface of the ribbed plate is composed of a curved surface bulged spherically from the inside to the outside.

  With such a configuration, even when a rounded article is accommodated, the contact area between the article and the inner wall surface is increased because the portion with which the outer periphery of the article contacts is bulged outward. It can grow and protect the article. Further, even if a large load is applied from above, since the force acts so as to open the cover plate outward, the release of the folding engagement is prevented.

  Here, it is preferable to disperse and provide a plurality of the spherical curved surfaces on the inner wall surface of the winding plate.

  Even in such a shape, a rounded article can be preferably accommodated.

  According to the folding container according to the present invention, since the inner wall surface of the ribbed plate bulges inward, the contact area with the rounded article is increased, so that the rounded article is preferably accommodated. Can do. Therefore, if the rounded article is a vegetable or the like, it is less likely to cause pain, and if it is an electronic component or the like, damage or destruction can be prevented.

  Furthermore, even if a load is applied from above due to stacking or the like, the upper end of the twist plate is supported by the frame, so that the engagement of this portion will not be released. And since the lower end part of a twisting board deform | transforms in the direction which bulges outward, the intensity | strength of a twisting board can be improved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a flip plate 28 employed in a folding container according to an embodiment of the present invention. In other words, this twisting plate 28 corresponds to the twisting plate 10 in FIG. That is, the upper end 28a is swingably supported by the frame 1, and the lower end 28b of the turn plate 28 is locked to the end wall 2a of the bottom plate 2 in a raised state. In other words, the turn plate 28 is housed in a folded state by folding the lower end 28b side in the direction of arrow A from the state of FIG.

  In such a twisted plate 28, ribs 12 in which groove-shaped recesses 12a are formed are formed in the horizontal direction at predetermined intervals in the height direction on the inner surface on the side where articles are accommodated. Thereby, the twisting board 28 is comprised so that predetermined intensity | strength may be exhibited.

  Furthermore, the inner surface 28c of the groin plate 28 according to the present embodiment is curved so as to bulge outward. That is, the swirl plate 28 swells in a spherical shape so as to spread outward.

  Therefore, when a rounded article 40, for example, a vegetable such as a pumpkin, is accommodated in such a folding container, the pumpkin 40 is accommodated along the inner wall surface 28c of the grill plate 28. Therefore, it is possible to prevent the fresh pumpkin 40 from being damaged, lost, or damaged.

  In addition, when the folding containers containing a large number of pumpkins 40 and the like are loaded in multiple stages, the load is transmitted to the crooking plate 28 and the like via the frame 1, but the force is applied to the lower end of the crooking plate 28. As shown by arrow B, 28b has an action of bulging outward. Therefore, the engagement between the lower end 28b of the turn plate 28 and the end wall 2a of the bottom plate 2 is not released. Further, in such a folding container, since the upper end of the turn plate 28 is swingably supported by the rectangular frame 1, the upper end portion of the turn plate 28 does not fall apart.

  Therefore, it is possible to always perform the stacking in a stable state.

  As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all, A various deformation | transformation is possible.

  For example, in the above embodiment, one spherical roundness is provided on the inner wall surface 28c of the turn plate 28, but instead, a spherical concave portion may be provided in a distributed manner. . In that case, it may be one in the upper half, one in the lower range, or two in total, or one each in the top, bottom, left and right, for a total of four. There is no particular limitation.

  Further, a spherical recess may be provided in the side plate 8 composed of the upper plate portion 4 and the lower plate portion 6 shown in FIG.

Further, the turn plate 28, the bottom plate 2, the side plate (not shown), and the like may be formed from a solid surface or may be configured from a plate body in which lattice-shaped holes are formed.
By configuring a mesh-like container body with holes formed in this way, it is excellent in drainage, cleanability and ventilation, and the inside can be seen from the outside. Suitable for housing goods.

  Moreover, the articles | goods accommodated in an inside are not limited to vegetables, A various article | item can be accommodated.

FIG. 1 is a sectional view showing an embodiment of a folding container according to the present invention. FIG. 2 is a perspective view showing an example of a conventional folding container disclosed in Japanese Utility Model Publication No. 4-15633.
