Abstract

<P>PROBLEM TO BE SOLVED: To provide a folding container whose upper divided sidewalls and lower divided sidewalls have almost square recessions formed on inner surfaces of the divided sidewalls to lessen contact areas between flip-up sidewalls and the upper/lower divided sidewalls upon assembling or folding the container, so that scuff formation in the most of the central part of the container is prevented when the upper/lower divided sidewalls are made of transparent or translucent synthetic resins to make the central part important for seeing an article stored in the container from the outside through the divided sidewalls. <P>SOLUTION: The folding container is composed of an upper frame 1, a bottom 2, the flip-up sidewalls 3 whose upper ends are pivoted on the upper frame 1, and the divided sidewalls 4 composed of the upper divided sidewall 4a and the lower divided sidewall 4b. The upper/lower divided sidewalls 4a and 4b have the almost square recessions 6 and 8 formed on their inner surfaces, respectively. This lessens the contact areas between the flip-up sidewalls 3 and the upper/lower divided sidewalls 6 and 8 upon assembling or folding the container, so that scuff formation in the most of the central part of the container is prevented when the upper/lower divided sidewalls 4a and 4b are made of transparent or translucent synthetic resins to make the central part important for seeing an article stored in the container from the outside through the divided sidewalls 4a and 4b. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a folding container used for storing, transporting or transporting various articles.

  Conventionally, an upper frame, a bottom, and a side wall (henceforth a side wall called a flip-up side wall) that is pivotable inwardly of a folding container, the upper end of which is hinged to the upper frame, are divided vertically. And a side wall (hereinafter, this side wall is referred to as a divided side wall) connected via an appropriate hinge portion, and the divided side wall is an upper divided side wall located above the hinge portion. And a lower divided side wall located below the hinge part, and the upper end of the upper divided side wall is hinged to the upper frame, and the lower end of the lower divided side wall is Folding containers that are hinged to the bottom are known.

  The folding container described above is assembled in a box shape. First, the flip-up side wall in a substantially vertical state is rotated inward of the folding container, and then the upper frame is moved closer to the bottom and the upper frame is moved upward. By overlapping the divided side wall and the lower divided side wall, the upper frame can be folded into a state of being overlapped with the bottom. Also, from the folded state, the upper frame is lifted so that the upper divided side wall and the lower divided side wall are substantially flush with each other, and the flip-up side walls are substantially vertical, and assembled into a box shape. It is configured to be able to.

  When assembling and folding the folding container described above, the side edges of the flip-up side walls are aligned with the inner surfaces of the upper and lower divided side walls (when the folding container is assembled into a box shape, The upper divided side wall and the lower divided side wall are scratched.

  In order to solve such a problem, a folding container in which an arc-shaped linear convex portion is formed in a region of the inner surfaces of the upper divided side wall and the lower divided side wall that are in contact with the side end portion of the raised side wall is disclosed in Patent Literature 1 is disclosed.

Japanese Utility Model Publication No. 5-75129

  In the conventional folding container described above, since the line-shaped convex portions project from the inner surfaces of the upper divided side wall and the lower divided side wall, the articles accommodated in the folded container are damaged or the articles are There was a problem that the traces of the convex portions remained and the commercial value of the article was lowered.

  In addition, in order to allow the articles contained in the folding container to be seen through from the outside, the upper divided side wall and the lower divided side wall are formed of a transparent resin. And when the linear convex part was formed in the lower division | segmentation side wall, there existed a problem that the accommodated goods became difficult to see.

  An object of the present invention is to solve the problems of the above-described conventional folding container.

  In order to achieve the above-mentioned object, the present invention comprises an upper frame, a bottom, a flip-up side wall whose upper end is pivotally supported by the upper frame, and a divided side wall having an upper divided side wall and a lower divided side wall. In the folding container, first, a substantially rectangular recess is formed on the inner surface of the upper divided side wall and the inner surface of the lower divided side wall, and second, an inclined edge is formed on the peripheral edge of the recess. The part is formed.

  Since the substantially square-shaped recess is formed on the inner surface of the upper divided side wall and the inner surface of the lower divided side wall, the upper divided side wall and the lower divided side wall are brought into contact with each other when the folding container is assembled and folded. Therefore, when the upper divided side wall and the lower divided side wall are formed of a transparent or translucent synthetic resin, most of the central area important for the perspective from the outside of the contained article is scratched. It is possible to prevent such a situation.

  In addition, since the inclined edge is formed on the peripheral edge of the recess formed on the inner surface of the upper divided side wall and the inner surface of the lower divided side wall, even if the article accommodated in the folding container contacts the inclined edge, The article is not damaged to the extent that the commercial value is impaired.

  Examples of the present invention will be described below, but the present invention is not limited to these examples unless it exceeds the gist of the present invention.

  The folding container is divided into an upper frame 1, a bottom portion 2, a flip-up side wall 3 whose upper end portion is hinged to the upper frame 1, and a division that is vertically divided and connected via an appropriate hinge portion h 1. The divided side wall 4 is composed of an upper divided side wall 4a located above the hinge part h1 and a lower divided side wall 4b located below the hinge part h1. In addition, the upper end portion of the upper divided side wall 4a is hinged to the upper frame 1, and the lower end portion of the lower divided side wall 4b is hinged to the bottom portion 2.

  The substantially vertical flip-up side wall 3 of the box-shaped folding container shown in FIG. 1 is rotated in the inner direction of the folding container so as to be in a substantially horizontal state as shown in FIG. By moving the hinge part h1 connecting the upper divided side wall 4a and the lower divided side wall 4b constituting the divided side wall 4 toward the inside of the folding container, the upper divided side wall 4a and the lower divided side wall 4b are overlapped. As shown in FIG. 3, the box-shaped folding container is configured to be folded into a compact state with a low height in a state where the upper frame 1 is overlapped with the bottom portion 2. Further, the upper frame 1 is lifted with respect to the bottom portion 2 so that the upper divided side wall 4a and the lower divided side wall 4b, which are overlapped in a substantially horizontal state, are set substantially vertically so as to be substantially flush with each other. 1, the folded side wall 3 whose upper end is hinged is rotated in a vertical direction from a substantially horizontal state, whereby the folded container in a folded state is configured to be assembled into a box shape.

  The upper divided side wall 4a is substantially parallel to the upper and lower horizontal sides of the upper divided side wall 4a, is substantially parallel to the opposite horizontal boundary line 5a near the upper and lower horizontal sides and the left and right vertical sides of the upper divided side wall 4a, and The area surrounded by the opposing vertical boundary 5b in the vicinity of the vertical side is assembled from the inner surface (the surface located inside the folding container when the folding container is assembled into a box shape) to the outer surface (the folding container is assembled into a box shape). , When they are swelled toward the outer surface of the folding container, the opposite vertical horizontal inclined edges 6a, the horizontal horizontal inclined edges 6b, and the vertical horizontal inclined edges 6a. And a substantially rectangular recess 6 formed by a flat portion 6c surrounded by left and right vertical inclined edges 6b.

  When the folding container is assembled in a box shape, the substantially square-shaped concave portion 6 formed on the inner surface of the upper divided side wall 4a is formed with a substantially square-shaped convex portion 6 'on the outer surface of the upper divided side wall 4a. However, the convex portion 6 ′ is configured not to protrude outward beyond the upper frame 1 and the bottom portion 2.

  Similarly, the lower divided side wall 4b is substantially parallel to the upper and lower horizontal sides of the lower divided side wall 4b, and is substantially parallel to the opposite horizontal boundary line 7a near the upper and lower horizontal sides and the left and right vertical sides of the lower divided side wall 4b. In addition, by bulging a region surrounded by the opposing vertical boundary line 7b near the left and right vertical sides from the inner surface toward the outer surface, the opposing vertical horizontal inclined edge portion 8a and the opposing left and right vertical inclined edge portion 8b. A substantially rectangular concave portion 8 is formed, which is composed of a flat portion 8c surrounded by the upper and lower horizontal inclined edge portions 8a and the left and right vertical inclined edge portions 8b.

  Similarly, the substantially square-shaped recess 8 formed on the inner surface of the lower divided sidewall 4b is formed on the outer surface of the lower divided sidewall 4b on the outer surface of the lower divided sidewall 4b. However, the convex portion 8 ′ is configured not to protrude outward beyond the upper frame 1 and the bottom portion 2.

  As described above, the inner surface of the upper divided side wall 4a is substantially parallel to the upper and lower horizontal sides of the upper divided side wall 4a, and is opposite to the horizontal boundary line 5a near the upper and lower horizontal sides and the left and right vertical sides of the upper divided side wall 4a. A substantially square-shaped recess 6 formed by bulging a region that is substantially parallel and surrounded by opposing vertical boundary lines 5b near the right and left vertical sides from the inner surface toward the outer surface is formed. The inner surface of the lower divided side wall 4b is also substantially parallel to the upper and lower horizontal sides of the lower divided side wall 4b, and substantially parallel to the opposing horizontal boundary line 7a near the upper and lower horizontal sides and the left and right vertical sides of the lower divided side wall 4b. Moreover, since the substantially rectangular recess 8 formed by bulging the region surrounded by the opposing vertical boundary line 7b near the right and left vertical sides from the inner surface toward the outer surface is formed, the above-described folding is performed. Container pair In the standing work and the folding work, the contact area of the upper divided side wall 4a and the lower divided side wall 4b with which the side end 3a of the raised side wall 3 abuts is small, and the inner surfaces of the upper divided side wall 4a and the lower divided side wall 4b Most of the central region is accommodated when the upper divided side wall 4a and the lower divided side wall 4b are made of a transparent or translucent synthetic resin because the side end 3a of the raised side wall 3 is not in contact. The majority of the central area, which is important for perspective from the outside of the folded article, is not scratched, so that the status of the article contained in the folding container is extended from the outside of the folding container over a long period of time. Therefore, it can be grasped reliably.

  In addition, since the peripheral vertical edge of the substantially rectangular recess 6 formed in the upper divided side wall 4a is formed with an opposing vertical horizontal inclined edge 6a and an opposing horizontal vertical inclined edge 6b, these inclined edges Even if the article accommodated in the folding container comes into contact with the parts 6a and 6b, the article is not damaged to the extent that the commercial value is impaired.

  Similarly, the peripheral edge of the substantially rectangular recess 8 formed in the lower divided side wall 4b is formed with a corresponding vertical horizontal inclined edge 8a and a horizontal horizontal inclined edge 8b. Even if the article accommodated in the folding container comes into contact with the edges 8a and 8b, the article is not damaged to the extent that the commercial value is impaired.
