Description

  The present invention relates to a lid structure for an assembly box, and more particularly to a lid structure for a gift box composed of a body box and a lid that covers the box.

  Conventionally, it is a gift box composed of a “body box” and “lid”, represented by an assembly box, and in particular, the body box (20) is a half size type (about half the depth: to show more products) In some cases, the stored item (30) may be protected by mounting another member (60) called "top pad" on the inner surface of the lid (50), which serves as a buffer function as a load resistance measure during stacking. It is common (see FIG. 4).

  However, when mounting such a separate member, it is necessary to prepare a top pad as a separate member, and in most cases, the top pad must be manually put on the body box. Cost problems and efficiency problems have occurred.

  The present invention solves the above problems related to a gift box composed of a “body box” and a “lid” in which another member called “top pad” is attached to the inner surface of the lid to provide a cushioning function. The present invention has been made in view of the above, and an object thereof is to provide a lid structure for an assembly box that is inexpensive and has a good work process (working efficiency).

  The invention of claim 1 of the present invention is a lid structure of an assembly box comprising a body box and a lid covering the body box, and a long side plate is continuously provided on two opposite sides of a square bottom plate via respective folding lines. The other two opposite sides are each provided with a short side plate via a bend line, and a tongue piece is formed at either end of each of the opposing side plates via a bend line. The tongue piece close to the bottom plate is cut along the fold line and partly cuts into the side plate on which the adjacent tongue piece is not formed, and the cut portion connects the tongue pieces continuously. The inclined piece is partitioned by a second fold line parallel to the fold line at the boundary between the side plate and the bottom plate, the long side plate, the short side plate and the tongue piece are bent along the fold line, and the outer surface of the tongue piece is adjacent to the side. When attached to the inner surface of the face plate and assembled to the lid, the inclined piece is Folded along two folding lines, the tip of the inclined piece is in contact with the bottom surface plate, wherein the inclined piece is characterized in that it forms only box receiving plate, a cover structure assembled box.

  As described above, according to the first aspect of the present invention, the long side plates are connected to the two opposite sides of the rectangular bottom plate via the folding lines, and the folding lines are respectively provided to the other two opposite sides. A short side plate is continuously provided through the plate, and a tongue piece is formed at one end of each of the opposing side plates via a fold line via a fold line, and the tongue plate near the bottom plate is along the fold line. Part of the side plate that is not formed with adjacent tongue pieces, and the cut part is parallel to the fold line at the boundary between the side plate and the bottom plate connecting the tongue pieces. When the inclined piece is divided by two fold lines, the long side plate, the short side plate and the tongue piece are bent along the fold line, and the outer surface of the tongue piece is bonded to the inner surface of the adjacent side plate and assembled to the lid, The inclined piece is bent along the second fold line, and the tip of the inclined piece Is in contact with the bottom plate, and the inclined piece forms a body box receiving plate, so when the stored item is stored in the body box and covered with a lid, the inclined pieces are formed at the four corners of the lid. The body box receiving plate hits the side plate of the body box and can receive the load applied from above.

  According to a second aspect of the present invention, in the first aspect of the present invention, the fold line formed at the boundary between any one of the opposing side plates and the tongue piece is a semi-cut fold line. It is a lid structure of an assembly box characterized by being.

  Thus, according to the second aspect of the present invention, the fold line formed at the boundary between one set of the side plates facing each other and the tongue piece is a semi-cut fold line. When making a box, it is easy to fold, so that the box making can be improved, and when the lid is crushed after use, each side plate and the bottom plate can be easily made flush. .

  The invention of claim 3 is the lid structure of the assembly box according to claim 1 or 2, wherein the material is made of cardboard.

  Thus, according to the invention described in claim 3, since the material is made of corrugated cardboard, it is possible to obtain an assembly box having a stacking strength.

  Thus, the lid structure of the assembly box of the present invention is a gift box that can withstand a load caused by loading or the like and can be easily manufactured without using a separate member during transportation or storage.

The present invention will be described in detail below based on one embodiment.
The lid structure of the assembly box of the present invention is, for example, a lid structure of an assembly box comprising a body box (20) and a lid (10) covering it as shown in FIGS.

That is, the long side plates (12, 12) are connected to the two opposite sides of the square bottom plate (11) via the folding lines (a).
Short side plates (13, 13) are continuously provided on the other two opposite sides via folding lines (a).

  Tongue pieces (14, 14, 14, 14) are formed at both ends of each long side plate (12, 12) via a fold line.

  Near the bottom plate (11) of each tongue piece (14, 14, 14, 14) is cut along a fold line. At the same time, a part of the side plate (the short side plate (13) in FIG. 1) on which the adjacent tongue piece is not formed is bitten, and the cut part is a side plate (continuously provided with the tongue piece (14)). In FIG. 1, the inclined pieces (15, 15, 15, 15) are defined by the second fold line (b) parallel to the fold line (a) at the boundary between the long side plate (12) and the bottom plate (11). The

  The lid blank (10a) having the above-described structure is first formed by bending the long side plates (12, 12), the short side plates (13, 13), and the tongue pieces (14, 14, 14, 14) by folding lines (a ), And then the outer surface of the tongue piece (14, 14, 14, 14) is bonded to the inner surface of the adjacent short side plate (13, 13) via an adhesive or the like. A lid structure is adopted.

  At that time, the tips of the inclined pieces (15, 15, 15, 15) come into contact with the bottom plate (11), respectively, and the inclined pieces (15, 15, 15, 15) form a body box receiving plate.

  In addition, by making the fold line formed at the boundary between the long side plates (12, 12) and the tongue pieces (14, 14) into a semi-cut fold line, each side can be easily crushed when crushing the lid after use. The face plate and the bottom plate can be coplanar, and the three-dimensional lid can be easily made flat.

  In addition, paper such as paperboard or cardboard can be used for the lid structure of the assembly box, but cardboard having a load resistance can be suitably used in consideration of use in a gift box.
