Description

  The present invention relates to a box for storing a container by folding a flat plate body from which corrugated cardboard is cut out, and more particularly to a hollow triangular column box for storing an elongated container such as an automobile molding or an oil gauge.

Various box bodies formed by folding to accommodate articles are known and disclosed (see, for example, Patent Documents 1 and 2).
In general, the box has a hollow quadrangular prism shape, and when the objects to be accommodated are accommodated and stacked, the boxes cannot be stacked more than the load at which the side plate does not buckle. In addition, when transported by a fork or vehicle in a stacked state, it is necessary to withstand a vertical load that is more than a mere static load, and it is necessary to consider the limitation on the number of stacked stages.
Even if the shape of the object to be accommodated is not suitable for a quadrangular prismatic box, it may be accommodated in the quadrangular prismatic box to occupy a wasteful loading volume. In addition, in the case of an elongated rectangular columnar box, a cross-sectional shape that can withstand bending load in addition to compressive load is required.

In order to improve the stacked load of the box, in the known technique, special means are provided at the side wall, particularly at the corner portion of the side wall so as to withstand the buckling load.
Therefore, the known technique has a drawback that it cannot be applied to a box formed by cutting a flat plate and bending it along a folding line.

  The present invention has been proposed in view of the above-mentioned problems of the prior art, and therefore the object of the present invention is to withstand sufficient compression and bending load by simply bending the cut flat plate along the folding line. To provide a box that can be used.

  According to the present invention, in the elongated triangular prism box body 1 for folding the cut flat plate 1Z to accommodate the object to be accommodated, the hollow triangular prism is elongated, equal width first, second, third and second. The four side plates 12, 14, 16, and 18 are formed by the first, second, third, and fourth side plates 12, 14, 16, and 18, respectively. , 15 and 17, a hollow triangular column is formed by the first, second and third side plates 12, 14 and 16, and the fourth side plate 18 is overlapped on the outside of the first side plate 12. The fourth side plate 18 is provided with an engaging portion 7 continuous with a fifth fold line 19, and the second side plate 14 is formed with an engaged portion 8 with which the engaging portion 7 is engaged. The engaging portion 7 is continuous with a fifth fold line 19 that is continuous with the edge line 3 of the fourth side plate 18, and The engaging portion 7 includes parallel edge lines 7a and 7b extending at right angles from both ends 19a and 19b of the fifth fold line 19, the edge line 7d at the tip parallel to the fifth fold line 19, and the parallel The outer edge lines 7f and 7f of the projections 7c and 7c provided between the edge lines 7a and 7b and the edge line 7d of the tip end portion are formed, respectively. The outer edge lines 7f and 7f are both parallel edge lines. 7a, 7b, and the engaged portion 8 has cut lines 8a, 8c provided on the fourth side plate 18 in parallel with and away from the first fold line 13, and the cut A first open line 8A is formed by an arc-shaped cut line 8b extending in a direction away from the first bent line 13 by continuing the lines 8a and 8c, and the cut lines are formed at both ends of the first open line 8A. The second open line 8D and the third open line 8E orthogonal to 8a and 8c are The end portions of the second and third open lines 8D and 8E are connected to a fourth folding line 9 that functions as a door hinge of the engaged portion 8, When the projection 7 is inserted into the engaged portion 8, the protrusions 7 c and 7 c are secured to the engaged portion 8.

The flat plate material is preferably cardboard.
By inserting the engaging portion into the engaged portion, strong engagement is achieved even without adhesion.

According to the present invention having the above configuration,
(A) Since the box body is formed in a hollow triangular column, there is an advantage that the volume of the box body can be reduced by reducing the gap in an elongated container such as an automobile molding or an oil gauge.
(B) Since the volume of the box can be reduced, there is an advantage that the amount of the corrugated cardboard used can be reduced.
(C) There is an advantage that the shape is simple and the assembly is easy, and the number of assembling steps is reduced.
(D) There is an advantage that it can be bent with a sharp shape.
(E) Since the box is formed in a hollow triangular column and the fourth side plate is stacked on the third side plate, the compressive strength is high, and the bending strength is high even if the box is lengthened. Can be accommodated safely and the number of stacked stages can be increased.
(F) There is an advantage that the storage space can be reduced if the flat body is stored flat and assembled when used.
(G) Since the engagement portion that is continuous with the third fold line is provided on the fourth side plate and the engaged portion with which the engagement portion engages is formed on the second side plate, the box body is not bonded. There is an advantage that strong engagement can be achieved.
(H) Since the cut plate is bent and the box is made without bonding, there is an advantage that it can be reused.
