Description

  The present invention relates to a two-piece box composed of a body box and a cover provided with a cover plate that opens and closes its top surface.

  In recent years, it has become common to order and purchase various products via the Internet, and as a result, mail orderers who have received orders will ship products of various sizes in boxes and send them to consumers. . At that time, if various types of boxes according to the size of the product are used in consideration of the transportation efficiency, the box management and packing for each type require a great deal of cost.

  As a countermeasure against such a situation, in Patent Document 1 below, a box whose height can be changed according to the product to be stored and its sealing device are proposed.

  First, as shown in FIG. 10, this box has a configuration in which side wall portions 61 that form each surface of a square cylindrical peripheral wall are continuously provided and the bottom surface is closed. The horizontal ruled lines 62 are inserted in the side wall portions 61 in accordance with the height of the product G, and the lower and upper portions of the horizontal ruled lines 62 are used as the side plates 63 and the short lid plates 64, respectively. The diagonal ruled line 65 which inclines inwardly from the both ends of the boundary to the tip is put.

  Next, as shown in FIG. 11, the short cover plate 64 is folded inward along the horizontal ruled line 62 while both side portions of the short cover plate 64 are folded along the oblique ruled line 65.

  And when actually shipping goods, although there is no description in following patent document 1, as shown in FIG. 12, the above box is made into the body box 51, and the cover 52 is covered on this. The cover 52 has a lid side plate 72 on the opposite side in the length direction of the lid plate 71 and a lid end plate 73 on the opposite side in the width direction. The cover 52 has a width across the lid plate 71 and the lid end plates 73 at both ends. A tear strip 74 such as a cut tape is provided at the center in the direction, and a score line 75 is provided at the boundary between the lid plate 71 and the lid end plate 73.

  When sealing the box using such a cover 52, the cover plate 71 is overlapped with the short cover plate 64, and the cover side plate 72 and the cover end plate 73 are attached to the side plate 63 of the body box 51.

  Further, when opening the box, the tear strip 74 is pulled from the cut portion of the lid end plate 73, and the lid end plate 73 and the lid plate 71 are cut into two parts, and the cut line 75 is cut. As shown in FIG. 13, the lid plate 71 is opened from each side plate 63 so as to stand up.

US Pat. No. 7,587,884

  However, in the box with a lid as described above, even when the lid plate 71 is opened, the short lid plate 64 remains on the top surface of the body box 51, so that the opening area of the body box 51 is small and the short lid plate 64 is opened separately. Otherwise, there is a problem that it is difficult to take out the product G.

  Accordingly, an object of the present invention is to make it possible to easily open a two-piece box with a lid composed of a body box and a cover so that the product can be taken out as it is opened.

In order to solve the above-mentioned problems, the present invention comprises a body box and a cover, and the body box has a configuration in which side wall portions that form each surface of a square cylindrical peripheral wall are connected, and a horizontal ruled line is formed on each side wall portion. And the lower and upper parts are side plates and short cover plates, respectively, and the adjacent short cover plates are connected at the corners. Insert a diagonal ruled line that inclines inward, fold both ends of the short cover plate along the diagonal ruled line, fold the short cover plate inward along the horizontal ruled line, and overlay the cover cover plate on the short cover plate. the lid plate and sealing paste to the outer surface of the side plate extending from the cover to the bisection, the lid box for opening a pair of side plates so as to erect a cover plate, respectively, in the cover, the box only pair on the sides and lid side plate of the cover plate connected to the side plate, Oh apart from the ridge line of the boundary Each put the lid borders Te without pasting acquire box the portion sandwiched between the lid border side of the cover, Paste the sides of the cover plate to the short cover plate, the boundary of the lid plate and the lid plate The part between the ridge line and the lid ruled line is not bent when the cover plate is closed with respect to the part pasted on the short cover plate and side plate of the body box, and along the cover ruled line when the cover plate is opened. And bent .

  In the box with a lid according to the present invention, if the cover cover plate is opened at the time of opening, the short cover plate of the body box is also opened in conjunction with it, so that the product can be easily opened and taken out.

  At that time, due to the paper thickness of the material, the gap between the boundary between the lid plate serving as the outer hinge and the lid side plate, and the boundary between the short lid plate serving as the inner hinge and the side plate is determined as the lid ruled line. Since it can escape with the bending of the portion sandwiched between the two, even if the cardboard is thick, it can be opened without difficulty.

  Moreover, after opening, it can be disassembled and folded into a flat state and discarded easily, like a normal grooving cardboard box.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  This box with a lid can be changed in height according to the goods to be stored, and is assembled from a cardboard box 1 and a cover 2 blank as shown in FIG.

  In the initial state, in the blank of the body box 1, the pair of long surfaces and the side wall portions 11 of the width surface are alternately connected, and the passage piece 12 is continuously connected to the outer end of the side wall portion 11 of one width surface. Yes. A bottom plate 13 is connected to the lower end of each side wall 11. At this stage, a ruled line for determining the height is not put in the body box 1.

  Such a blank of the body box 1 is folded along a ruled line which is a diagonal position at the time of assembly among the ruled lines at the boundary of the adjacent side wall parts 11, and the passage piece 12 is attached to the opposite side wall part 11. Keep it in a flat state.

  In the blank of the cover 2, the lid side plate 22 is connected to the opposite side in the length direction of the lid plate 21, and the lid end plate 23 is connected to the opposite side in the width direction, and the width of the lid plate 21 and the lid end plates 23 at both ends is provided. A tear strip 24 such as a cut tape is provided at the center in the direction, and a cut start portion 25 is formed with a notch sandwiching both ends thereof. A cut line 26 is formed at the boundary between the cover plate 21 and the cover end plate 23, except for the cut start portion 25.

  Further, on both side portions of the lid plate 21 and the lid side plate 22, a lid ruled line 27 is formed in parallel with the ridgeline, with a gap from the ridgeline at the boundary thereof. .

  When assembling the blank as described above and packing the product, as shown in FIG. 2, in the body box 1, the side wall 11 is bent so as to form a square cylindrical peripheral wall, and the bottom plate 13 on the width surface side and The bottom plate 13 on the long surface side is sequentially bent inward and bonded together to close the bottom surface.

  Thereafter, as shown in FIG. 3, when the product G is boxed, the height of the product G is detected by the sealing device, and the horizontal ruled lines 14 are put on the side wall portions 11 according to the height, The lower and upper portions are the side plate 15 and the short lid plate 16, respectively, and oblique ruled lines 17 that incline inward from both ends of the boundary with the side plate 15 to the tip are put in the opposing short lid plate 16.

  Here, the horizontal ruled line 14 is a ruled line pressed from the back side of the cardboard, and the oblique ruled line 17 is a half-cut ruled from the back side of the cardboard to the middle in the thickness direction.

  The oblique ruled lines 17 are shown in the short cover plate 16 on the width surface side, but may be included in the short cover plate 16 on the long surface side.

  Next, as shown in FIG. 4, the short cover plate 16 is folded inward along the horizontal ruled line 14 while folding both end portions of the short cover plate 16 along the oblique ruled line 17. In the blank of the cover 2, the pair of lid side plates 22 and the lid end plates 23 are bent downward from the lid plate 21.

  Thereafter, as shown in FIG. 5, the cover 2 is placed on the top surface of the body box 1, the cover plate 21 is overlapped on the short cover plate 16, and the portion sandwiched between the cover ruled lines 27 on each side of the cover 2 is covered. Without sticking to the box 1, the lower part of the lid side plate 22 from the lid ruled line 27 is pasted on the long side plate 15 and inside the lid ruled line 27 on the side of the lid plate 21, as shown by hatching in the figure. The part is affixed to the short cover plate 16, and the part excluding the cut start portion 25 of the lid end plate 23 is affixed to the side plate 15 of the width surface to complete the sealing.

  Note that this affixing need not be performed on the entire surface of the hatched portion, but may be a point-like adhesion by spraying a hot melt adhesive or the like.

  On the other hand, when opening the box, the tear strip 24 is pulled from the cut start portion 25, and the lid end plate 23 and the lid plate 21 are torn into two parts, and the cut line 26 is cut. 7, the lid plate 21 is opened from each side plate 15 so as to stand up.

  In the box with a lid as described above, when opening the lid plate 21 of the cover 2 when opening, the short lid plate 16 of the body box 1 is also opened in conjunction with the box 1 without being bothered by the short lid plate 16. The product G can be taken out by easily opening the top surface of the product.

  At that time, due to the paper thickness of the material, a deviation occurs between the vicinity of the boundary between the cover plate 21 and the cover side plate 22 serving as the outer hinge and the vicinity of the boundary between the short cover plate 16 serving as the inner hinge and the side plate 15. Can be released along with the bending of the portion sandwiched between the lid ruled lines 27, so that even if the cardboard is thick, it can be opened without difficulty.

  Moreover, after opening, it can be disassembled and folded into a flat state and discarded easily, like a normal grooving cardboard box.

  As shown in FIG. 8, the lid end plates 23 at both ends of the lid plate 21 are provided only on the portion that connects to the cut start portion 25 of the lid plate 21, and are attached to the side plates 15 on the width surface of the body box 1. Thus, when opening, the lid plate 21 can be divided and opened simply by peeling the lid end plate 23 from the side plate 15 and pulling the tear strip 24, and the resistance at the time of opening can be reduced.

  Further, when the lid end plate 23 is omitted completely and the cover 2 is attached to the body box 1 with only the lid side plate 22 as shown in FIG. 9, the lid 2 is torn from the cut-off portion 25 of the lid plate 21 when opened. Since the lid plate 21 can be divided and opened simply by pulling the belt 24, the opening workability is further improved although the packaging strength is slightly reduced.

  By the way, in the said embodiment, although the box with a lid | cover which sealed with one cover 2 and divided | segmented the cover 2 with the tear strip 24 at the time of opening was illustrated, two sheets each affixed on each side plate 15 of the body box 1 respectively. The cover 2 may be engaged and sealed at the top surface of the body box 1 by a cut or the like made at the tip, and when opening, the engagement may be released and the cover plate 21 may be opened. .

  In addition, although the cover 2 illustrated what covers only the top surface of the body box 1, the cover 2 covers the bottom surface of the body box 1 through the lid side plate 22 extending from the lid plate 21 to the lower end of the body box 1. In this case, the bottom plate 13 of the body box 1 can be omitted.
