Description

  The present invention relates to a paper storage box such as corrugated cardboard. More specifically, the invention comprises a lower case or a rectangular barrel case with a rectangular parallelepiped with an open top surface, and an upper lid that covers the lower case. The present invention relates to an improvement in a structure that can be manufactured so as not to be displaced.

  There is a storage box 20 made of cardboard as shown in FIG. This consists of a lower box 1 of a rectangular parallelepiped with an open upper surface and an upper lid 2 covering the lower box 1. The upper lid 2 is composed of a rectangular top plate 2a slightly larger than the rectangular cross section of the lower box 1, and side plates 2b provided along the four side edges of the top plate 2a. The upper side of the lower box 1 is covered.

  Along with that, positioning holes 1b and 2c for positioning the lower box 1 and the upper lid 2 are formed on both sides of the side plate 1a of the lower box 1 near the upper edge and the side plate 2b of the upper lid 2. Is provided. An example of a storage box that includes a lower box and an upper box and is provided with joint insertion holes so as to communicate with the overlapping portions of these side plates can be seen in Patent Document 1.

  The storage device of this type is applied when storing an article with a high height, and stores the product in the lower box 1 instead of operating the upper lid 2 from above the lower box 1. When trying to cover the upper lid 2, a product having a high height is stored such that the position of the upper edge of the lower box 1, that is, the position of the upper lid 2 is the same as or higher than the operator's line of sight. It is used when doing.

On the other hand, if the amount of storage is small, such as a mandarin orange box, and the box is small and its height is low, the top lid is connected to the top edge of the box so that it can be folded. The upper lid can be operated from above the box.
Japanese Patent No. 3223448 (page 2-3, FIG. 1)

  By the way, when the upper lid 2 is produced in the storage box 20 having the above-described configuration, as shown in FIG. 3A, the top of the lower lid 1 in the unfolded state of the upper lid 2 is formed on the upper edge of the lower box 1 previously formed. The upper part 2 is formed by placing the boundary part between the plate 2 a and the side plate 2 b in correspondence with each other and bending the boundary part along the upper edge of the lower box 1 in this state.

  Then, the positioning holes 2c provided in each of the four side plates 2b of the upper lid 2 and the positioning holes 1b provided on the upper side of the four side plates 1a of the lower box 1 coincide with each other. FIG. 3B shows a state in which the upper lid 2 is completed on the lower box 1.

  However, when the upper lid 2 is produced by the above method, when the adjacent side edges of the side plates 2b of the upper lid 2 are connected to each other as shown in FIG. By using a thick corrugated cardboard in order to give a dimensional error at the time of manufacture and to make the upper lid 2 rigid, the seam of the side edge of the adjacent side plate 2b becomes as shown in FIG. It may enter into a rectangular area and act to distort the outer shape of the lower box 1 indicated by a two-dot chain line.

  As a result, the positioning holes 1b and 2c of the lower box 1 and the upper lid 2 originally have to overlap exactly as shown in FIG. 4 (c). ) As shown in FIG.

  In that case, it is not possible to connect the side edges of adjacent ones of the side plates 2b while leaving the displacement of the positioning holes as it is. For example, the positioning holes of the side plates 2b of the upper lid 2 and the side plates 2b of the lower box 1 are not provided. The work must be done with force and labor, for example, by inserting the insertion member into the overlap or by correcting the shape of the upper lid 2 so that the positioning hole is exactly aligned with the operator's hand.

  Therefore, the present invention includes a lower box 1 having a rectangular parallelepiped with an open top surface and an upper lid 2 covering the rectangular box. The upper lid 2 includes a rectangular top plate 2a and side plates 2b arranged along four side edges thereof. The side plate 2b surrounds and covers the upper side surface of the lower box 1, and the lower box 1 and the upper lid 2 overlap the portion where the upper side surface of the lower box 1 and the side plate 2b of the upper lid 2 overlap. In a paper storage box 10 made of cardboard or the like in which positioning holes are provided on both sides, the positioning holes of the upper lid 2 and the lower box 1 are made to coincide with each other, and the side plate 2b of the upper lid 2 is placed. It is an object of the present invention to make it easy to connect the side edges of adjacent objects.

  This can be applied not only to the lower box 1 of the rectangular parallelepiped with the upper surface opened, but also to a case of a rectangular cylinder, but is represented by the lower box 1 hereinafter.

  In order to solve the above-mentioned problems, the present invention provides a protrusion on the upper edge of the lower box, and when the upper cover is placed on the lower box, the protrusion is in a position where it contacts on the boundary between the top plate and the side plate of the upper cover. A configuration is adopted in which a positioning groove is provided in which the protrusion can be inserted.

  Since it did in this way, in order to assemble a storage box as described above, first, with respect to the upper lid, the side plate connected to the side edge of the top plate is not folded and the top plate and the side plate are left unfolded. A protrusion provided on the upper edge of the lower box is inserted and placed in a positioning groove provided at the boundary. In this state, the four side plates are bent.

  Then, the positioning hole provided on the upper part of the four side plates of the lower box and the positioning hole of the side plate of the upper lid are constrained by the engagement between the ridge and the groove so that the positioning holes of the upper lid are aligned with each other. Even if the joints between the side edges of the side plates are deformed so that both the positioning holes are displaced, the positioning holes remain exactly coincident with each other.

  Since the present invention is configured as described above, by positioning the protrusions of the lower box in the grooves of the upper lid, the positioning holes provided in the upper portions of the four side plates of the lower box and the corresponding positioning of the side plates of the upper lid Since the holes are exactly aligned, the top lid assembler does not care about the positioning holes on the side plates of the top lid and the bottom box, and can concentrate only on the side edges of adjacent side plates. Can be assembled easily.

  Embodiments of the present invention will be described below with reference to the drawings. In the figure, the same elements as those of the conventional element will be described using the same reference numerals as those of FIGS. FIG. 1A is a perspective view of the unfolded state of the lower box 1 and the upper lid 2 of the storage box 10 of the present embodiment. The lower side of the figure is the lower box 1, and the upper side is that of the developed state of the upper lid 2.

  As shown in the figure, the lower box 1 is provided with a long hole 1b for positioning the upper lid 2 in the middle in the width direction near the upper edges of the four side plates 1a with its longitudinal direction oriented in the horizontal direction. Yes. Further, a protrusion 1c is provided at the center of a pair of paired improvement edges of the four side plates 1a.

  On the other hand, when the upper lid 2 is in the unfolded state, a rectangular top plate 2a slightly larger than the square of the cross section of the lower box 1, and a side plate 2b connected to each of the four side edges of the top plate 2a, Positioning on the boundary line between the top plate 2a and the side plate 2b, when the protrusion 1c protruding from the upper edge of the lower box 1 can be inserted when it is placed on the upper edge of the lower box 1. A groove 2d is provided.

  In order to assemble the upper lid 2, the positioning groove 2d at the boundary between the top plate 2a and the side plate 2b is fitted and placed on the protrusion 1c on the upper edge of the lower box 1 with the upper lid 2 in the unfolded state. In this state, the four side plates 2b are bent to connect the side edges of the adjacent side plates 2b. FIG. 1B shows the completed state.

  At this time, as shown in FIG. 4, the outer shape of the upper lid 2 is deformed at the joint, and when the upper lid 2 is put on the lower box 1, the positioning holes 1b and 2c are displaced. 1C and FIG. 1B, the protrusion 1c of the lower box 1 is fitted in the groove 2d of the upper lid 2, so that the positioning holes 1b and 2c are Matches exactly. Accordingly, there is no need to correct the displacement of the positioning holes 1b and 2c as in the case where the protrusions 1c and the grooves 2d are not provided, and the side edges of the side plates 2b adjacent to the upper lid 2 are connected to each other. Easy to connect.

  In the above description of the embodiment, the lower box 1 having a rectangular parallelepiped with an open top surface is taken as an object of displacement from the upper lid 2, but as described above, the object of the present invention is such a lower box. The present invention is not limited to the box 1 and can also be applied to a rectangular barrel case.

  That is, a positioning hole is provided in each of the four side plates near the upper edge of the trunk case, the positioning hole, and a positioning hole provided in the side plate of the upper lid that covers the upper edge of the trunk case. Are overlapping.

  The present invention is composed of a lower case or a rectangular tube case of a rectangular parallelepiped with an open top surface, and an upper cover covering the lower box and the case. The upper cover is formed along a rectangular top plate and its four side edges. It consists of a side plate that is provided continuously, and covers and covers the upper side surface of the lower box and the trunk case with the side plate, and the upper side surface of the lower box and the trunk case overlaps with the side plate of the upper lid, The present invention can be applied to all paper storage boxes in which positioning holes for positioning the lower box or the trunk case and the upper lid are provided on both sides.
