Description

  The present invention relates to a simple assembly box that can be used as a multi-purpose box, the main purpose of which is a box file for storing a plurality of holders, documents and the like together.

  Conventional box files are usually made of cardboard, corrugated paper, or a flexible plastic sheet material, and one-touch boxes having a bottom-locked bottom surface have been widely used (Patent Documents 1 and 2). ). It is an assembly box in which hatched portions are glued by a development drawing as shown in FIG. 8 of Patent Document 1, and many bottom lock types have been used. This bottom-lock box file can be transported and stored in a folded state, and is also widely used efficiently because it is folded at the time of sale.

However, these bottom lock type box files are folded along the four side surfaces extending from the bottom due to the structure of the bottom (FIG. 7 of Patent Document 2). This remains as a permanent distortion in materials such as cardboard and cardboard, and the box is distorted in a diamond shape after the box file is assembled. This rhombus distortion looks very bad because it accumulates when many box files are arranged. In addition, the bottom of the bottom lock has a place where several sheets of material are folded over and is not satisfactorily. This is a state in which there is anxiety about the uniformity and strength of the bottom surface.

  The problem to be solved by the present invention is that the one-touch assembly box often used in a box file or the like is not a bottom lock type, and after assembly, there is no rhombus distortion, and the bottom surface is one sheet bottom and the adhesive peels off. It is to provide a one-touch assembly box that can be used with box files without worry.

  A first problem-solving means is a box made of a flexible sheet plate having an open top or an openable lid, and the box is configured to be foldable. In this case, side side plates are extended through the folding lines on the opposite sides of the three sides that are connected at right angles to the substrate, and the central side plate is extended on the center side through the crease, and each side plate is parallel to each of the three sides of the substrate. The center folder is connected to the middle fold of the side plate at the center side plate side edge of the two side side plates facing each other through the fold line. The assembly box is characterized by extending inside the box.

  The second problem-solving means is that a lid extends on the opposite side of the central side plate of the substrate via a folding line, and a lid side piece extends on both ends of the lid via the folding line. First, the assembly box described in the problem solving means 1 is provided.

  The box according to the present invention is a state in which the upright plate extending at the end on the center side plate side of the two opposite side side plates is folded to the side side plate side, and the middle folding line including the center side plate is placed outside or inside the box. By folding, the box is folded and folded so that the faceplates without creases are facing each other. When the box is raised and the two standing pieces inside the box are bent at right angles toward the central side plate, the standing state of the box is locked. The box is assembled almost in one touch in this way, and there is no rhomboid distortion of the box after assembly, which was a drawback of the conventional bottom lock type. Also, a single box with no glue on the bottom surface (the center side plate in this application) is easy. Assembled into. Further, if the upright piece bent toward the center side plate is returned to the side surface side, the box can be easily folded from the center folding line.

  If both sides of the lid are placed inside the box side and the tip of the lid is inserted into the insertion slot, the lid will be completely closed, resulting in a solid hexahedron box. Box file. At this time, if the length of the side piece is adjusted to the width of the side plate, the reinforcing effect near the opening can be obtained both when the lid is closed and when the box file format is used.

  FIG. 1 shows a box file development drawing of an embodiment of the present invention. In the sheet P obtained by punching out one piece of thick paper, a dotted line indicates a folding line, and a solid line indicates a cutting line. Side side plates 5 and 5 and a central side plate 6 are provided on three sides of the substrate 1 through fold lines. The central side plate 6 becomes the bottom surface after being assembled as a box file. The three side plates have center fold lines 25, 27, 27 at the center along the entire length of the side plate, and upright plates 8, 8 are arranged on the side edges of the opposite side side plates 5, 5 on the center side plate 6 side through the fold lines. The middle fold lines 31 and 31 connected from the middle fold lines 27 and 27 are also provided at the center of the upright plate.

  FIG. 2 is a plan view showing a state in which the upright pieces 8 and 8 of the punched piece P in the state of FIG. 1 are bent on the side side plates 5 and 5 via the folding lines 32 and 32.

  FIG. 3 is a plan view of the state in which the side-side plate 5 is bent from the folding line 27 together with the upright plate 8 to the substrate 1 side from the state of FIG. The glue margin 7 is hatched in order to show the glued state. In this state, the upright piece 8 is folded inside the side plate 5 and therefore cannot be seen from this figure.

  FIG. 4 is a plan view of the state in which the central side plate 6 is bent from the state of FIG. In this state, the box is basically in a folded state.

  FIG. 5 is a perspective view of the state of FIG. The side side plates 5 and 6 are folded from the middle fold line 27 and shown in a folded state.

  FIG. 6 is a perspective view showing a state in which the center of the three side plates is pushed from the states of FIGS. 4 and 5 to cancel the folded state and raise the box. The figure is partly cut out to show the inside of the box. In FIG. 6, the upright piece 8 is in contact with the side plate 5 side, and the upright piece 8 has not yet supported the upright of the box. In this state, if the hand is released, the state returns to the state close to FIG.

  FIG. 7 shows a state in which the hand is put in the box in the state of FIG. 6 and the upright piece 8 is bent at a right angle from the folding line 32 to the central side plate 6 side. When the two standing pieces touch the central side plate 6, the standing of the box is maintained. FIG. 7 is a perspective view showing a state where the box is held upright. Further, the reinforcing piece 3 extended on the upper surface plate 3 is folded inside the box via the folding line 33 and bonded to the inner surface of the upper surface plate 3. The lid side pieces 10 on both sides of the lid 4 are bent.

  FIG. 8 is a perspective view showing a state in which the lid side piece 10 is inserted into the box along the side side plate 5 from the state of FIG. 7 and the lid insertion piece tip 9 b is inserted into the insertion port 11 of the top plate 3. .
