Embodiment 1
Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to FIGS. In FIG. 2, FIG. 3, FIG. 4, and FIG. 7, various broken lines formed on the packaging material 1 are shown by a one-dot chain line. Moreover, the broken line in these drawings is a virtual line given for convenience of explanation, and is not a broken line.

<Overall structure of packaging material>
First, the whole structure of the packaging material 1 is demonstrated using FIG. 1 and FIG. FIG. 1 is a view showing an application example of the packaging material 1 according to the present embodiment to a door 100, where (a) is a perspective view and (b) is a sectional view (XX ′ sectional view). FIG. 2 is a development view showing an example of the packaging material 1.

  As shown in FIGS. 1A and 1B, the packaging material 1 includes a front surface 101, a rear surface 102, two side surfaces 103, and two end surfaces 104 (one is not suitable) of a door 100 (eg, sliding door, hinged door). At least a part of each of them is shown. In other words, the packaging material 1 functions as a packing member that packs (wraps) the door 100 in order to reduce the impact that can be received from the outside when the door 100 is transported.

  Here, the front surface 101 and the back surface 102 of the door 100 are the widest planes in the door 100 and are planes facing each other. Any of the widest planes may be the front surface 101 or the back surface 102. That is, one of the widest planes may be referred to as the front surface 101 and the other as the back surface 102. The two side surfaces 103 are flat surfaces that are substantially perpendicular to the front surface 101 and the back surface 102 and that extend in the longitudinal direction and face each other. The two end surfaces 104 are flat surfaces that are substantially perpendicular to the front surface 101, the back surface 102, and the two side surfaces 103, and are opposed to each other and extend in the short-side direction.

  In the example of FIG. 1, the entire side surface 103 of the door 100, a part of the front surface 101 connected to the side surface 103, a part of the back surface 102, and a part of the two end surfaces 104 are covered with the packaging material 1. . In addition, the packaging material 1 is provided on each of the side surfaces 103. As shown in FIG. 1B, the packaging material 1 is provided on each side surface 103 so as to have a U-shaped cross section. Thus, packing only a part of the door 100 using the packaging material 1 is also referred to as simple packing.

  The packaging material 1 of the present embodiment is made of paperboard (eg, cardboard), and is packed along a plurality of fold lines formed on the packaging material 1 to pack a part of the door 100 as shown in FIG. . Thus, by simply packing the door 100 using the packaging material 1, the two side surfaces 103, and the four corner portions (the portion where the side surface 103 and the end surface 104 are connected, which are easily damaged by an external impact, And the vicinity thereof can be protected.

  The packaging material 1 has, for example, the configuration shown in FIG. 2 in order to realize the packaging of the door 100 as shown in FIG. Specifically, when the packaging material 1 covers the door 100, the first surface 11 facing the front surface 101 of the door 100, the second surface 12 facing the back surface 102 of the door 100, and the side surface of the door 100. The third surface 13 is provided opposite to the third surface 13.

  The first surface 11, the second surface 12, and the third surface 13 are each a printing area PA where information such as a manufacturer of the packaging material 1 and a cautionary note regarding transportation of the door 100 is printed, and non-printing that is not performed. And a print area NPA. In the first surface 11, the second surface 12, and the third surface 13, the printing area PA and the non-printing area NPA are symmetrical with respect to the center line CL that passes through the center of the packaging material 1 and extends in the short direction. It is provided to become. In the present embodiment, the printing area PA is limited to the area and the center area from the end of the packaging material 1 to a predetermined distance, and a non-printing area NPA is provided between the plurality of printing areas PA. .

  Here, the height (length in the longitudinal direction) of the door 100 differs depending on the type. In order to be applicable to the door 100 having various heights, the packaging material 1 is cut according to the height of the door 100. Specifically, the packaging material 1 is cut in the lateral direction at two locations, the portion sandwiched between the two locations is removed, and the remaining two portions are bonded with an adhesive tape or the like. At this time, when the information is printed in various regions of the packaging material, a part of the information may be cut off. However, the packaging material 1 is provided with a non-printing area NPA. Therefore, by cutting the non-printing area NPA for adjusting the height of the packaging material 1, it is possible to avoid that part of the information is cut off. That is, according to the packaging material 1, the door 100 having various heights can be packed without cutting off a part of the above information, and the corner portion of the door 100 can be formed regardless of the height of the door 100. Can be protected.

  In addition, for example, when the door is packed by cutting the vicinity of the edge of the packaging material and bonding with adhesive tape, etc., the corner of the door is protected by the packaging material itself compared to packing the door without cutting. Sometimes it was not stable. Therefore, stabilization of the protection has been achieved by a buffer member provided at a corner of the door. However, according to the packaging material 1 of the present embodiment, since the non-printing area NPA is provided at a position away from the end of the packaging material 1 by a predetermined distance, even when the packaging material 1 is cut and used. The protection of the corners of the door 100 by the packaging material 1 itself can be stabilized. In addition, in the packaging material 1, since the protection function of the corner | angular part of the door 100 is provided in the edge part as mentioned later, it is comprised so that the said edge part vicinity may not be cut | disconnected.

  Moreover, when packing the door 100 with the packaging material 1 using a packaging machine, the packaging machine cuts the packaging material 1 at two places in the non-printing area NPA according to the height of the door 100 to be packed, and The part sandwiched between the two places is removed, and the remaining two parts are bonded with an adhesive tape or the like. In the packaging material 1, the non-printing area NPA is provided so as to be symmetric with respect to the center line CL. Therefore, even if any end of the packaging material 1 is sent to the packaging machine, the cutting position is set. It can be set in the non-printing area NPA. Therefore, even when a packaging machine is used, the packaging material 1 can be cut according to the height of the door 100 without cutting off printed information.

  In addition, when the door 100 used as the packaging object of the packaging material 1 is being fixed to 1 type, since there is no need for a cutting | disconnection, the non-printing area | region NPA does not need to be provided in the packaging material 1. FIG.

  As shown in FIG. 2, the packaging material 1 has a substantially rectangular shape. Therefore, it is sufficient to prepare at least a plate material that is a material of the packaging material 1 according to the size of the packaging material 1.

  In addition, as shown in FIG. 2, at each end of the packaging material 1, a line obtained by extending the boundary line BL <b> 1 between the first surface 11 and the third surface 13, and the second surface 12 and the third surface 13. By forming a notch along a line extending the boundary line, the first tongue piece 21 corresponding to the first surface 11, the second tongue piece 22 corresponding to the second surface 12, and the third surface 13 A third tongue piece 23 corresponding to the above is formed. Furthermore, in the present embodiment, the boundary line BL1 and the boundary line BL2 are each provided with two broken lines (folded lines F11 to F14 shown in FIG. 3). Details of the end of the packaging material 1 will be described later.

  In addition, as shown in FIG. 4 and FIG. 5, for example, various broken lines are actually realized as continuous minute depressions (ruled lines) on the surface of the packaging material 1 on the side in contact with the door 100 (surface on the back side). Has been. 2, 3, and 7, it should be noted that various broken lines are illustrated on the surface of the packaging material 1 on which printing is performed (surface on the front side) for convenience.

<Details of end of packaging material>
Next, the specific structure of the edge part of the packaging material 1 is demonstrated using FIG. FIG. 3 is a development view illustrating an example of an end portion of the packaging material 1. In addition, in FIG. 3, although only one of the edge parts of the packaging material 1 is shown, it is the same shape also about the other.

  As shown in FIG. 3, the end portion of the packaging material 1 has a first tongue piece 21 connected to the first surface 11, a second tongue piece 22 connected to the second surface 12, and a third surface 13. A connected third tongue piece 23 is formed.

  The first tongue piece 21, the second tongue piece 22, and the third tongue piece 23 are cut out by cutting out the ends of the boundary lines BL1 and BL2 by a predetermined length on a rectangular paperboard (corrugated cardboard in this embodiment). It is provided by forming. Therefore, the 1st surface 11, the 2nd surface 12, the 3rd surface 13, the 1st tongue piece 21, the 2nd tongue piece 22, and the 3rd tongue piece 23 (in other words packaging material 1) are comprised from the same material. ing. That is, the first surface 11 and the first tongue piece 21 are continuous, the second surface 12 and the second tongue piece 22 are continuous, and the third surface 13 and the third tongue piece 23 are continuous.

  Note that, as described later, the predetermined length is a part of the end surface 104 of the door 100 to be packed in a state where the first tongue piece 21, the second tongue piece 22, and the third tongue piece 23 are bent. Any length that can be protected may be used.

  The first tongue piece 21 is formed with two broken lines F1 and F2 extending in the short direction of the packaging material 1 (direction substantially perpendicular to the boundary lines BL1 and BL2). By folding the first tongue piece 21 along the polygonal lines F1 and F2, the rectangular regions R1 and R2 (two rectangular pieces) can be overlapped and raised.

  The rectangular region R1 has a length W1 in the longitudinal direction (the direction in which the boundary lines BL1 and BL2 extend), and the rectangular region R2 has a longitudinal length W2. The broken line F2 is provided at a position separated from the boundary between the first surface 11 and the first tongue piece 21 by a rectangular region M1 (described later), and the broken line F1 is separated from the broken line F2 by a length W2. It is provided at a position (a position where the length W1 is separated from the end of the first tongue piece 21). That is, the broken line F <b> 2 is provided at a position closest to the first surface 11 of the first tongue piece 21.

  Similarly, two broken lines F3 and F4 extending in the short direction of the packaging material 1 are formed on the second tongue piece 22. By folding the second tongue piece 22 along the broken lines F3 and F4, the rectangular regions R3 and R4 (two rectangular pieces) can be overlapped and raised.

  The rectangular region R3 has a length W3 in the longitudinal direction, and the rectangular region R4 has a length W4 in the longitudinal direction. The broken line F4 is provided near the boundary between the second surface 12 and the second tongue piece 22, and the broken line F3 is separated from the broken line F4 by a length W4 (from the end of the second tongue piece 22). It is provided at a position where the length W3 is separated. That is, the broken line F <b> 4 is provided at a position of the second tongue piece 22 closest to the second surface 12.

  Then, a plurality of rectangular pieces (referred to as a “first rectangular piece group”) superimposed by bending the first tongue piece 21 and a plurality of rectangular pieces superimposed by folding the second tongue piece 22. (Referred to as “second rectangular piece group”) is in a state where a part of the end surface 104 of the door 100 can be covered. Thereby, it becomes possible to protect the corner | angular part (a part of end surface 104) of the door 100, without using a buffer member separately. In other words, the rectangular regions R <b> 1 to R <b> 4 (more specifically, the first rectangular piece group and the second rectangular piece group) function as a buffer member that reduces the impact that the corner portion of the door 100 can receive from the outside. .

  Further, the third tongue piece 23 is also formed with a polygonal line F5 extending in the short direction of the packaging material 1. The polygonal line F5 is provided in the vicinity of the boundary between the third surface 13 and the third tongue piece 23. By folding the polygonal line F5, a part of the side surface 103 of the door 100 can be covered. Thereby, it becomes possible to protect the corner | angular part (a part of side surface 103) of the door 100, without using a buffer member separately. It can be said that the third tongue piece 23 also functions as the buffer member.

  In other words, the packaging material 1 includes the first tongue piece 21, the second tongue piece 22, and the third tongue piece 23, thereby providing one sheet having a buffering portion that softens the impact that the corner portion of the door 100 can receive from the outside. It can be said that it is made of paperboard.

  Further, three or more broken lines may be formed on each of the first tongue piece 21 and the second tongue piece 22. In other words, each of the first tongue piece 21 and the second tongue piece 22 may be formed with at least two broken lines. When three or more broken lines are formed, three or more rectangular pieces can be formed. This example will be described later with reference to FIG. A plurality of broken lines may be formed on the third tongue piece 23. In other words, the third tongue piece 23 may be formed with at least one broken line. This example will be described later with reference to FIG.

  In the present embodiment, the length W1 of the rectangular area R1 is shorter than the length W3 of the rectangular area R3, and the length W2 of the rectangular area R2 and the length W4 of the rectangular area R4 are the same. That is, the length of the rectangular regions R1 and R2 in the first tongue piece 21 from the end of the packaging material 1 is longer than the length of the rectangular regions R3 and R4 in the second tongue piece 22 from the end of the packaging material 1. The broken line F2 is provided closer to the end side (outer side) of the packaging material 1 than the broken line F4. Therefore, the first tongue piece 21 is formed with a rectangular region M1 having a length of (W3 + W4) − (W1 + W2).

  Consider the case where this rectangular area M1 is not provided ((W1 + W2) = (W3 + W4)). In this case, when the packaging material 1 is folded at the boundary lines BL1 and BL2 in order to overlap the first rectangular piece group and the second rectangular piece group, the first rectangular piece group and the second rectangular piece group. Will collide with each other. As a result, the shape of the first rectangular piece group or the second rectangular piece group may be deformed, and protection of the corners of the door 100 may become unstable. By providing the rectangular area M1 as described above, the first rectangular piece group and the second rectangular piece group can be prevented from colliding with each other, and the corner portion of the door 100 can be stably protected.

  In addition, when the packaging material 1 is bent along the boundary lines BL1 and BL2, an area is provided in the end portion of the packaging material 1 so that the first rectangular piece group and the second rectangular piece group do not collide with each other. That's fine. For example, a rectangular region corresponding to the rectangular region M <b> 1 may be provided in a region of the second tongue piece 22 that is in contact with the second surface 12. Moreover, the rectangular area different from rectangular area R1-R4 is provided in both the area | region which contact | connects the 1st surface 11 of the 1st tongue piece 21, and the area | region which contact | connects the 2nd surface 12 of the 2nd tongue piece 22. Also good. Even in this case, each rectangular area (that is, the positions of the broken lines F2 and F4 that define each rectangular area) is such that the packaging material 1 overlaps the first rectangular piece group and the second rectangular piece group. When bent, the surface of the first rectangular piece group and the surface of the second rectangular piece group face each other (in the example of FIG. 3, the rectangular region R1 and the rectangular region R4 face each other). .

  That is, the packaging lines F2 and F4 are arranged so that the first tongue piece 21 and the second tongue piece 22 face each other (in other words, the first rectangular piece group and the second rectangular piece group overlap each other). The boundary lines BL1 and BL2 are provided at different positions in the extending direction so that the surface of the first rectangular piece group and the surface of the second rectangular piece group face each other when 1 is bent. . That is, the first rectangular piece group and at least one of the first tongue piece 21 and the second tongue piece 22 so that the surface of the first rectangular piece group and the surface of the second rectangular piece group are opposed to each other. It is only necessary to provide a thickness-corresponding region having a length corresponding to the thickness of at least a part of the second rectangular piece group.

  As shown in FIG. 3, when the door 100 is packed, the first surface 11, the second surface 12, and the third surface 13 face the front surface 101, the back surface 102, and the side surface 103 of the door 100, respectively. Thus, the broken line for folding back the packaging material 1 along the boundary lines BL1 and BL2 is provided. In the present embodiment, the boundary line BL1 is provided with polygonal lines F11 and F12 that serve as a boundary between the first surface 11 and the third surface 13. The boundary line BL <b> 2 is provided with polygonal lines F <b> 13 and F <b> 14 that serve as a boundary between the second surface 12 and the third surface 13.

  By folding the packaging material 1 along the polygonal lines F11 and F13, the door 100 having the height of the side surface 103 (the length in the perpendicular direction of the surface 101) corresponding to the length between the polygonal lines F11 and F13 can be packed. It becomes. In addition, by folding along the broken lines F12 and F14, the door 100 having the height of the side surface 103 corresponding to the length between the broken lines F12 and F14 can be packed. In this way, it is possible to pack two types of doors 100 having different side surface 103 heights.

  Note that the configuration is not limited to the configuration in which two broken lines are provided for each of the boundary lines BL1 and BL2, and three or more broken lines may be provided. It becomes possible to pack various doors 100 having different heights of the side surface 103 by the amount of the broken line. Further, the number of broken lines provided on the boundary lines BL1 and BL2 may be different between the boundary line BL1 and the boundary line BL2. In other words, it suffices that at least one of the polygonal line serving as the boundary between the first surface 11 and the third surface 13 and the polygonal line serving as the boundary between the second surface 12 and the third surface 13 is provided at a plurality of positions. However, when the door 100 to be packed with the packaging material 1 is fixed to one type, it is only necessary to provide one broken line for each of the boundary lines BL1 and BL2.

  Further, the width W5 in the short direction of the third tongue piece 23 is set to the width W6 of the third surface 13 (the two boundary lines BL1 and BL1) so that the third tongue piece 23 can be folded back to the third surface 13 side. The length between BL2) is set below. As described above, the position of folding along the boundary lines BL1 and BL2 differs depending on the height of the side surface 103 of the door 100. In order to reliably pack the door 100 having the smallest height of the side surface 103, which is assumed as a packaging target of the packaging material 1, the width W5 of the third tongue piece 23 is equal to or less than the length between the broken lines F11 and F13. It is preferable that

<Packing process>
Next, the packaging process of the door 100 by the packaging material 1 is demonstrated. The door 100 is placed on a protective film (eg, vinyl resin), and the entire door 100 is covered with the protective film. Thereafter, the protective film is pulled in a tight state and thermocompression bonded. Thereafter, the packaging material 1 is provided on the side surface 103 of the door 100, and the packaging material 1 is bent along the polygonal lines F1 to F5, whereby (1) the entire side surface 103 and (2) a part of the surface 101 connected to the side surface 103. The packaging material 1 covers a part of the back surface 102 and a part of the end surface 104. Packaging with the packaging material 1 is performed on both side surfaces 103. That is, as shown in FIG. 1, the portion of the door 100 other than that covered with the packaging material 1 is protected only by the protective film. Thereafter, the door 100 and the packaging material 1 are bound by a binding band. In addition, the bending process (assembly process of the packaging material 1) of the packaging material 1 will be described later.

  Examples of the binding band include a PP band (polypropylene band). Moreover, it is preferable that a binding location is multiple places (example: 3 places or 4 places).

  The packing process (including the assembling process of the packaging material 1) is performed by a packaging machine that packs the door 100 with the packaging material 1. In this case, the packing operation of the door 100 by the packaging material 1 can be automated. However, the packing operation may be performed manually.

<Packaging material assembly process>
Next, the assembly process of the packaging material 1 is demonstrated using FIG. 4 and FIG. 4 and 5 are diagrams for explaining a part of the assembly process of the packaging material 1. In the description of the assembling process, the door 100 to be packed is not shown, but actually, the packaging material 1 is provided on the door 100.

  As shown to (a) of FIG. 4, in the 1st tongue piece 21, rectangular area | region R1 is turned back to the rectangular area | region R2 side by the broken line F1 near the edge part of the packaging material 1. As shown in FIG. In the second tongue piece 22, the rectangular region R <b> 3 is folded back to the rectangular region R <b> 4 side at a fold line F <b> 3 on the side close to the end of the packaging material 1. Further, the third tongue piece 23 is folded back to the third surface 13 side along the broken line F5.

  As a result, as shown in FIG. 4 (b), the rectangular regions R1 and R2 face each other in the first tongue piece 21, and the rectangular regions R3 and R4 face each other in the second tongue piece 22. And overlap each other. That is, in the first tongue piece 21, the rectangular regions R1 and R2 are doubled (twice the thickness of the packaging material 1) to form a first rectangular piece group, and in the second tongue piece 22, The regions R3 and R4 are doubled to form a second rectangular piece group. Further, the portion where the third tongue piece 23 and the third surface 13 are opposed to each other is also doubled.

  The rectangular regions R1 and R2 that form the first rectangular piece group and the rectangular regions R3 and R4 that form the second rectangular piece group are each lightly fixed with an adhesive (eg, hot melt adhesive). Similarly, the third tongue piece 23 and the third surface 13 are also lightly fixed with an adhesive.

  Next, as shown in FIG. 4 (b), in the first tongue piece 21, the first rectangular piece group is bent by about 90 ° to the first surface 11 side along the polygonal line F2, and the first rectangular piece group is formed. Stand up (the first rectangular piece group is erected substantially perpendicularly to the first surface 11). In the second tongue piece 22, the second rectangular piece group is bent by about 90 ° toward the second surface 12 along the polygonal line F <b> 4, and the second rectangular piece group is raised (the second rectangular piece group is raised to the second surface 12. To stand substantially perpendicular to). Thereby, the shape of the packaging material 1 will be in the state shown to (c) of FIG.

  That is, as shown in FIG. 4C, the rectangular regions R1 and R2 can be overlapped and raised by folding the first tongue piece 21 along the folding lines F1 and F2. Similarly, by folding the second tongue piece 22 along the broken lines F3 and F4, the rectangular regions R3 and R4 can be overlapped and raised.

  Next, as shown in FIG. 4 (d) and FIG. 5 (a), the first surface 11 is bent toward the third surface 13 along the fold line F11 in order to wrap around the side surface 103 of the door 100 and the vicinity thereof. Then, the third surface 13 is bent toward the second surface 12 along the broken line F13. Thereby, the shape of the packaging material 1 will be in the state shown to (e) of FIG. 4, and (b) of FIG. That is, as shown in FIG. 4E and FIG. 5B, the first rectangular piece group obtained by bending the first tongue piece 21 and the second tongue piece 22 were obtained. A part of the end surface 104 of the door 100 can be covered with the second rectangular piece group. In place of the folds F11 and F13, for example, fold lines F12 and F14 may be used. Further, the second surface 12 may be bent toward the first surface 11 side.

  In other words, the packaging material 1 forms a first rectangular piece group and a second rectangular piece group at the end portion thereof, and stands up and overlaps so as to cover a part of the end surface 104. It is configured to be able to. Specifically, at least the positions of the broken lines F1 to F4 are defined in the packaging material 1 so as to realize the configuration. Moreover, the packaging material 1 is comprised so that a part of side 103 of the door 100 can be covered by the 3rd tongue piece 23 being turned back by the broken line F5. Specifically, the position of the broken line F5 is defined in the packaging material 1 so as to realize the configuration.

  Here, the rectangular region M1 described above is formed in the first tongue piece 21. Therefore, when the packaging material 1 is bent at the polygonal lines F11 and F13, a part of the rectangular area M1 faces the rising second rectangular piece group, so that it does not collide with the rising first rectangular piece group. No. Therefore, as shown in FIGS. 4E and 5B, when the first surface 11 is bent toward the second surface 12, the surface of the first rectangular piece group and the second rectangular shape are formed. It will be in the state which the surface of one group opposes.

  FIG. 4E shows an end where the first tongue piece 21 overlaps the second tongue piece 22 when viewed from the second surface 12 side. As shown in FIG. 2, the packaging material 1 has a first tongue piece 21 and a second tongue piece at each of both ends so that the first tongue pieces 21 and the second tongue pieces 22 face each other in the longitudinal direction. A tongue piece 22 is provided. Therefore, at both ends in the longitudinal direction of the packaging material 1, the first tongue piece 21 overlaps the second tongue piece 22 when viewed from the second surface 12 side. That is, the first tongue piece 21 overlaps from the outside of the second tongue piece 22 at both ends thereof.

  4 (e) and FIG. 5 (b), in the packaging material 1 after assembly, the first rectangular piece group and the second rectangular piece group are quadruple (of the packaging material 1). 4 times the thickness). On the other hand, the part of the 3rd surface 13 which opposes the 3rd tongue piece 23 is double as above-mentioned. That is, when the packaging material 1 is assembled, the portion of the packaging material 1 facing the end surface 104 near the corner of the door 100 is quadruple, and the packaging material 1 faces the side surface 103 near the corner. The part is doubled.

  Therefore, it is possible to protect the corner portion of the door 100, which is an important part as a protection target, without being separately provided with a cushioning member, and easily subjected to impact from the outside only by bending the packaging material 1. Further, even when the packaging material 1 is made of thin paperboard, the corners can be protected. Therefore, it can be said that the effect of protecting the corners is high in terms of simple packaging. And the risk of damage accompanying the transportation of the door 100 can be reduced by using the packaging material 1.

  Further, at the construction site where the door 100 is transported, neither packaging materials nor cushioning members are required, and therefore waste. When the packaging material 1 is used, it is not necessary to use a buffer member, and therefore only the packaging material 1 may be discarded. Therefore, the amount of waste can be reduced. Moreover, since the packaging material 1 is manufactured with paperboard, it can be manufactured at low cost and can be easily discarded.

  Further, only through the process shown in FIG. 4, the thickness of the portion facing the end face 104 and the side face 103 can be set to a thickness that can protect the corner of the door 100. Therefore, by using the packaging material 1, the corners of the door 100 can be protected by a simple method.

  Moreover, since the part facing the end surface 104 is quadruple, when the door 100 packed with the packaging material 1 is leaned, a protection effect comparable to the case where the buffer member is provided at the corner is obtained. .
