DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail based on examples shown in the drawings. FIG. 1 is a developed view showing a blank plate of a paper box 10 according to the present invention, and FIG. 2 is a perspective view showing a state in which the top is similarly opened. 3 is a perspective view showing a state in the middle of folding the trunk, FIG. 4 (A) is a front view when the trunk is folded, and FIG. 4 (B) is a folding of the trunk. FIG. First, the blank plate of the paper box 10 will be described. The blank plate (paper box 10) is composed of one cardboard plate, and each face plate is divided by a plurality of creases as will be described later.
[0015]
That is, as shown in FIG. 1, side plates 14, 16 are connected to both side edges of the front plate 12 via folding lines 40, 42, and a folding ruler 44 is provided on the side edge of one side plate 16. A back plate 18 is continuously provided. A sticking plate 20 is connected to the side edge of the back plate 18 via a crease 46, and the front plate 12, the side plates 14 and 16, and the back plate 18 constitute a body portion of the paper box 10. ing. Note that the sticking plate 20 may be connected to the side edge of the other side plate 14 instead of the back plate 18 via folding lines.
[0016]
In addition, the inner bottom plate 22 is connected to the lower edge of the front plate 12 via a crease 48, and the inner top plate 24 is connected to the upper edge via a crease 50. When the paper box 10 is assembled, the inner top plate 24 is a partition plate that divides the inside of the box up and down into two, and two creases 52 that are parallel to the creases 50 are provided at a predetermined interval. Yes. Further, an outer bottom surface plate 26 is continuously provided on the lower edge of the back plate 18 via a crease 54, and an outer top surface plate 28 is continuously provided on the upper edge via a crease 56. A bottom side flap 30 and a top side flap 32 are connected to the lower and upper edges of the side plates 14 and 16 via creases 58 and 60, respectively.
[0017]
Further, a notch 38 having a substantially U-shape in front view is provided at the center of the inner top plate 24 on the crease 50 side, and the tip thereof reaches the front plate 12 with a predetermined length. A cut-out 38 that is substantially U-shaped when viewed from the front is also provided at the center of the inner bottom plate 22 on the side of the crease 48, and the front end thereof reaches the front plate 12 by a predetermined length. Thus, by setting the imaginary straight line connecting the end portions of the respective cuts 38 as the hinge portion H, the locking flap 36 is formed.
[0018]
An insertion flap 34 is connected to the lower edge of the outer bottom plate 26 and the upper edge of the outer top plate 28 via folding lines 62 and 64, respectively, at the center of the folding lines 62 and 64. Are provided with notches 62A and 64A having a width into which the locking flap 36 can be inserted. Further, on both sides of the substantially U-shaped cut 38 and on the creases 48 and 50, cuts 48A and 50A continuous with the cut 38 are provided with a predetermined length, with the hinge portion H as the center. The insertion flap 34 can be inserted into the cuts 48 </ b> A and 50 </ b> A by folding the locking flap 36 and retracting it.
[0019]
Therefore, when the paper box 10 is assembled, first, the creases 40 to 46 are bent, and the surface of the sticking plate 20 is bonded to the back surface of the side plate 14. As the adhesive at this time, hot melt, cold glue or the like can be adopted. In this way, the rectangular cylindrical body of the paper box 10 is configured. Next, the bottom side flap 30 is bent along the crease 58, and the inner bottom plate 22 is bent along the crease 48. Then, the outer bottom plate 26 is bent along the crease 54.
[0020]
Further, the insertion flap 34 is bent along the crease 62 and inserted into the notch 48A provided on the crease 48. At this time, the locking flap 36 formed by the substantially U-shaped notch 38 is inserted. It is inserted after being bent away by the hinge part H and retracted. Thereafter, the locking flap 36 is inserted into a cut 62A provided on the crease 62. Thereby, the bottom part of the paper box 10 is sealed.
[0021]
Subsequently, the inner top plate 24 is bent along the crease 50. At this time, the two creases 52 provided at a predetermined interval are bent in the opposite direction to the crease 50. Then, with the front end side of the crease 52 far from the front plate 12 being in contact with the back surface of the back plate 18, the inner top plate 24 is placed at a predetermined position in the box (the crease 50 and the crease 52 are By being supported at a position that is lowered from the upper edge by an interval, the inside of the box is divided into two vertically divided plates (see FIG. 2). As described above, when the storage space in the box is vertically divided into two, for example, a product such as a precision instrument can be stored below, and an instruction manual for the product can be stored on the inner top plate 24. Become.
[0022]
Thereafter, the top side flap 32 is bent along the crease 60, the outer top surface plate 28 is bent along the crease 56, and the insertion flap 34 is bent along the crease 64. Then, in the same manner as described above, the insertion flap 34 is inserted into the notch 50A on the crease 50, and the locking flap 36 is inserted into the notch 64A on the crease 64. Thereby, the top of the paper box 10 is sealed.
[0023]
In this way, the paper box 10 is assembled. Next, a description will be given of the collecting means when the paper box 10 is discarded, that is, the folding means (folding curve) and the disassembling means (cutting line). As shown in FIG. 1, a folding line that facilitates folding or a cutting line that facilitates disassembly is provided at predetermined positions of the outer top plate 28, the back plate 18, the outer bottom plate 26, and the insertion flap 34. It has been. The fold curve is configured, for example, by providing non-penetrating perforations (half cut) or creases (both not shown) in parallel with the creases 40 to 46 on either one of the front and back surfaces. A perforation 66 penetrating both surfaces is provided in parallel with the creases 40 to 46.
[0024]
Then, these folding lines and cutting lines (perforation 66) are obtained after assembling the trunk (after bonding the sticking plate 20 to the side plate 14), for example, as shown in FIG. 3 and FIG. When the crease 44 is folded and folded into a substantially flat shape, the crease 42 is provided at a position where the crease 42 is located (the distance from the crease 44 is the same length as the width of the side plate 16). When a folding line or a cutting line (perforation 66) is provided in such a part, as shown in FIGS. 5 (A) and 5 (B) corresponding to FIGS. 4 (A) and 4 (B), respectively, For example, when disassembling, the paper box 10 can be easily divided into two by cutting the perforation 66 and also cutting the crease 42 overlapping the perforation 66.
[0025]
Therefore, when the paper box 10 is discarded, the paper box 10 can be folded or dismantled easily and suitably by hand, without performing an operation such as peeling off the sticking plate 20 from the side plate 14. Conventionally, even a cardboard paper box 10 that has been bulky to be disposed of can be compactly integrated into approximately half the size, that is, the width of the front plate 12 at the time of disposal. Can reduce labor (time and effort). Since the crease 42 is a fragile part, it is relatively easy to cut along the crease 42 during disassembly, but the crease 42 also has a perforation or cutting line as a cutting line. A half cut or the like may be provided. In that case, the crease 42 can be easily cut.
[0026]
1 to 5 show an example in which another perforation as a cutting line is provided, and predetermined positions of the inner top plate 24, the front plate 12, and the inner bottom plate 22, that is, FIG. As shown in FIG. 4, a perforation 68 is provided at a portion where the crease 46 is located (the distance from the crease 40 is the same length as the width of the side plate 14). In this way, the perforations 66 and 68 as the cutting lines can be provided up to two in the case of folding the crease 40 and the crease 44, and when cutting, either one can be cut. Needless to say, the two may be cut together. When two are cut together, the paper box 10 is divided into four. Further, when the perforation 68 is provided, the perforation 46 can be easily cut in the same manner as described above if a perforation, a half cut, or the like as a cutting line is provided on the crease 46 overlapping therewith.
[0027]
In any case, the folding lines and the cutting lines (perforations 66, 68) may be arranged at appropriate positions so that they can be bent or cut easily depending on the type (shape) of the paper box 10. For example, in the case of a paper box in which face plates such as the inner top face plate 24 and the inner bottom face plate 22 are not connected (not required), the perforation 68 is naturally provided only on the front plate 12. Moreover, although the thing of illustration shows that the perforation 66 is extended also in the insertion flap 34, since the insertion flap 34 is comprised comparatively compactly and can be bent or cut | disconnected easily, The insertion flap 34 may not be provided with the perforation 66.
[0028]
In the paper box 10 configured as described above, one process of the disassembling work will be described below by taking the case of the perforation 66 shown in FIGS. 1 to 5 as an example. Note that the folding work is merely folding instead of cutting in the dismantling work, and thus the description thereof is omitted. When the paper box 10 is discarded, as shown in FIG. 2, the top portion has already been opened by taking out the commodity and the like. Therefore, first, the bottom of the paper box 10 is opened. At this time, the retaining flap 36 can be easily opened simply by removing it from the notch 62A and further removing the insertion flap 34 from the notch 48A.
[0029]
Then, as shown in FIGS. 3 and 4, the crease 40 and the crease 44 are folded, and the body portion is folded into a substantially flat shape. That is, folding is performed so that the back surface of the side plate 14 contacts the back surface of the front plate 12 and the back surface of the back plate 18 contacts the back surface of the side plate 16. Then, the crease 42 and the perforation 66 overlap in front view, and the crease 46 and the perforation 68 overlap in rear view. In this state, one of the perforations, in this case, the perforation 66 is cut, and the crease 42 overlapping the perforation 66 is cut. At this time, the crease 42 is weaker than other parts because the crease is attached, so it can be easily cut, but if a perforation or the like as a cutting line is provided, Cut along it.
[0030]
When the perforation 66 and the crease 42 are cut in this way, as shown in FIG. 5, the paper box 10 is divided into two. For example, when they are stacked and bundled, they can be combined to a width of about the width of the front plate 12. it can. Therefore, the labor when discarding such a paper box 10, that is, time and labor, is reduced, and the disposal space is also reduced. Needless to say, the same effect can be obtained by cutting the perforation 68 and the crease 46.
[0031]
Although the paper box 10 is configured as described above, a paper box 11 according to another embodiment that does not depend on how the body is folded will be described with reference to FIGS. That is, a case will be described in which the folds 40 and 44 can be folded and the folds 42 and 46 can be cut even when folded. For convenience of explanation, the same components as those in FIGS. 1 to 5 are denoted by the same reference numerals and description thereof is omitted.
[0032]
As shown in FIG. 6, the outer top plate 28, the back plate 18, and the outer bottom plate 26 are symmetrical to the perforation 66 shown in FIG. 1 (the distance from the crease 46 is the same as the width of the side plate 14). A perforation 70 is provided at the length position). Similarly, in the inner top plate 24, the front plate 12, and the inner bottom plate 22, the perforation 68 shown in FIG. 1 and a symmetrical position (the distance from the crease 42 is the same length as the width of the side plate 16). A perforation 72 is provided at the position).
[0033]
With such a configuration, even if the body portion is folded by the creases 40 and 44 as shown in FIG. 7 or folded by the creases 42 and 46 as shown in FIG. Since one of the perforations 66 to 72 always overlaps, the paper box 11 can be easily cut by the same action as described above. That is, in the case of the folding method shown in FIG. 7, the perforation 66 and the crease 42 are overlapped, and the perforation 68 and the crease 46 are overlapped, which is exactly the same as FIG. 1 to FIG. In the case of the folding method shown, the perforation 70 and the crease 40 overlap, and the perforation 72 and the crease 44 overlap.
[0034]
Even in the case of such folding, the paper box 11 can be easily divided into two by cutting either the perforation 70 and the crease 40 or the perforation 72 and the crease 44. it can. Needless to say, when both the perforation 70 and the crease 40 and the perforation 72 and the crease 44 are cut, the paper box 11 is divided into four. Further, perforations and half cuts as cutting lines may be provided on the creases 40 and 44 in accordance with the perforations 70 and 72 to be cut.
[0035]
In any case, one to four perforations as cutting lines are provided, and thereby the paper box is divided into two to four. In other words, it is possible to provide up to four perforations. The larger the number of perforations, the more flexibility in how to fold the body and the more convenient the cutting work. In practice, however, the strength of the paper box The quantity may be set as appropriate in consideration of the shape and weight of the contents to the extent that is not impaired. In the case of a fold curve, it is possible to provide up to four as with the cutting line, but it is sufficient to fold the paper box in two.
[0036]
As described above, according to the present invention, when the body portion of the paper box is folded, the folding line along the crease is formed on the face plate facing (contacting) the crease (and its extension line) in the body portion. Alternatively, since a cutting line (perforation or the like) is provided, when the paper box is discarded, the paper box can be easily folded or divided into a plurality of pieces. Therefore, the operation of discarding the paper box can be performed conveniently (the width of the paper box to be discarded can be reduced to a compact width), and the labor for disposal can be reduced.
[0037]
In addition, it is not possible to cut along the cutting line, but it is also possible to simply bend it, and any one of the folding line and the cutting line can be adopted. Further, the shapes of the paper boxes 10 and 11 are not limited to those shown in the drawings. For example, the inner top plate 24 may not be configured to also serve as a partition plate. Further, the paper box is not limited to one made of corrugated cardboard, and the same applies to cardboard close to it.
[0038]
【The invention's effect】
According to the present invention, even a paper box formed of cardboard such as cardboard can be easily folded, divided, or disassembled, and can be collected in a compact manner. Can be.
