Description

  The present invention relates to a packing material such as a plate-like body, for example, a solar cell module with a mold.

  Conventionally, the packaging material of a solar cell module with a formwork is known. For example, in Patent Document 1, a first side wall is erected on each opposing edge on the bottom surface, and a second side wall is erected on each other opposing edge, and the first side wall and the second side wall are provided. Are engaged with each other and held in an upright state, and the first upper surface covering portion of the first side wall and the second upper surface covering portion of the second side wall are respectively folded in order to form the upper surface peripheral portion of the solar cell module with formwork. A sun with a formwork which covers and overlaps the second side wall via a protective part by inserting it into an insertion opening formed in the intermediate part in the height direction of the first side wall. The battery module is packed.

  In this case, a substantially L-shaped cut is formed at each of the front and rear edges of the first side wall, and the fold extends from the front and rear edges to the end of the cut at a height corresponding to the height of the solar cell module with a mold. And a partition plate is formed by raising a portion defined by the cuts and creases in the first side wall along the creases, so that the solar cell modules with upper and lower molds are supported in a buffered state.

JP 2009-173332 A

  However, in the package of the solar cell module with formwork described above, since the partition plate is formed using the first side wall, the width of the partition plate cannot be larger than the height of the solar cell module with formwork, The length also cannot form an L-shaped cut having a large length in the front-rear direction due to the strength of the first side wall. Therefore, as the solar cell module with a mold becomes larger, there is a drawback that it is not possible to secure a required large partition plate even though a large partition plate is required.

  This invention is made | formed in view of such a problem, and when a plate-shaped object, such as a solar cell module with a formwork, is piled up and down and packed, the corner part of an upper and lower plate-shaped object is required. The present invention provides a packing material that can be supported while being buffered by a large-area partition piece.

  In the present invention, a side surface and a side surface side upper surface portion are sequentially connected to a side edge of the bottom surface portion via a fold line, while a back surface portion and a front surface portion are respectively connected to the upper and lower end edges of the bottom surface portion via a fold line. The rear upper surface portion and the front upper surface portion are connected to the upper end edge of the rear surface portion and the lower end edge of the front surface portion through a fold line, respectively, and the side edge of the rear surface portion and the side edge of the front surface portion. Partitions are connected to each other through folds at the edges, and each partition has a set-length cut extending in the vertical direction from the upper and lower edges and a horizontal direction connecting the end of the cut from the side edges. The partition piece is partitioned by a fold extending to the center, and an insertion hole is formed in the intermediate portion in the width direction near the upper and lower end portions of the side surface portion corresponding to the partition piece of each partition portion. Is.

  According to the present invention, after punching according to each development view, the two packing materials are arranged symmetrically with a length interval in the width direction of the plate-like body, and the plate-like body is mounted over the bottom surface portion thereof. Put. Next, the back surface portion and the front surface portion are folded and raised along the fold line with respect to the bottom surface portion, and the side surface portion is folded and raised along the fold line with respect to the bottom surface portion. Further, after the partition pieces of the respective partition portions are bent along the folds, the partition portions are folded along the fold lines along the fold lines with respect to the back surface portion and the front surface portion so as to be along the side surface portions. At this time, the partition piece of each partition portion is inserted into the insertion hole formed in the side surface portion, and is disposed on the side surface side upper surface of the corner portion of the plate-like body through the insertion hole. Next, after the next plate-like body is overlaid on the plate-like body previously arranged, the side-surface-side upper surface portion is folded along the crease with respect to the side surface portion, and is put on the upper surface of the plate-like body. Further, the back side upper surface part is folded along the crease to cover the upper surface of the plate-like body with respect to the back surface part, and the front side upper surface part is folded along the crease with respect to the front part to cover the upper surface of the plate-like body. .

  As a result, the height of the side part, the back part, and the front part when packing the plate-like body stacked one above the other with the packing material by providing the partition part that partitions the partition pieces on the back part and the front part respectively. Regardless of whether or not the plate-shaped body stacked up and down via the large-area partition piece can be supported while buffering at the corners, it is possible to reliably prevent the upper and lower plate-shaped bodies from contacting each other can do.

  In the present invention, it is preferable that a locking portion having a set width is formed at a side edge of each partition portion up to a position where a fold of the partition piece exceeds a set length. Thereby, after inserting each partition piece into the insertion hole, the partition portion is pushed in and moved along the side surface portion through the back surface portion and the front surface portion by a length corresponding to the width of the locking portion. Therefore, the locking portion of the partition portion can be locked to the inner surface side of the insertion hole end edge portion of the side surface portion, thereby reliably preventing the partition piece from coming out of the insertion hole.

It is preferable that insertion holes are respectively formed in the vicinity of the upper and lower end portions along the fold line with the side surface portion. Thereby, when the back side upper surface part is folded along the crease and covered on the upper surface of the upper plate-like body with respect to the back surface part, and the front side upper surface part is folded along the crease with respect to the front part and When covering the upper surface of the plate-like body, the respective locking pieces continuously provided on the rear surface side upper surface portion and the front surface upper surface portion are bent along the creases, respectively, to the corresponding insertion holes formed on the side surface upper surface portion, respectively. By inserting, it is possible to prevent the locking pieces from slipping out, that is, the back-side upper surface portion and the front-side upper surface portion from jumping up.

  In the present invention, a locking groove that can be locked to each insertion hole edge portion of the side surface side upper surface portion along each crease between the back surface side upper surface portion and the front surface side upper surface portion is provided at the edge of the locking piece. Preferably it is formed. Thus, after each locking piece is inserted into the corresponding insertion hole formed in the side surface upper surface portion, each locking piece is inserted through the back surface portion and the front surface portion by the length corresponding to the depth of the locking groove. Since the back side upper surface part and the front side upper surface part where the pieces are continuously provided can be pushed in and moved, the locking groove is locked to the inner and outer surfaces of the insertion hole end edge part of the side surface side upper part. It is possible to reliably prevent the locking piece from coming out of the hole.

  In the present invention, a cut having a set length or a cut line is formed from the upper edge along the crease between the partition part and the back surface part, and from the lower edge along the crease between the partition part and the front part. It is preferable that a cut having a set length or a notch including the cut is formed. As a result, when each locking piece is inserted into the corresponding insertion hole formed on the side surface upper surface portion, it becomes possible to elastically deform the upper end edge of the back surface portion and the front surface portion outward by the length of the cut. The locking piece can be easily inserted into the insertion hole.

  In the present invention, the left and right side portions and the left and right side surface upper surface portions are sequentially connected to the left and right side edges of the bottom surface portion through folds, while the back surface portion and the front surface portion are provided on the upper and lower edge portions of the bottom surface portion. The back side upper surface part and the front side upper surface part are connected to the upper end edge of the back part and the lower end edge of the front part via the crease, respectively, and the left and right sides of the back part. A partition is connected to each of the left and right side edges of the end edge and the front part via a fold line, and each partition has a cut with a set length extending in the vertical direction from the top and bottom edges. A partition piece is defined by a fold extending in the horizontal direction connecting the end edge to the end of the cut, and a difference in width direction intermediate portion in the vicinity of the upper and lower end portions of the left and right side portions corresponding to the partition piece of each partition portion. The insertion holes are formed respectively.

  According to the present invention, after punching according to each developed view, the packing material is arranged, and the plate-like body is placed on the bottom surface portion thereof. Next, the back surface portion and the front surface portion are folded and raised along the fold line with respect to the bottom surface portion, and the left and right side surface portions are folded and folded along the fold line with respect to the bottom surface portion. Further, after the partition pieces of the respective partition portions are folded along the folds, the partition portions are folded along the fold lines with respect to the back surface portion and the front surface portion so as to be along the left and right side portions. At this time, the partition pieces of the respective partition portions are inserted into the insertion holes formed in the left and right side portions, and are arranged on the side surface upper surfaces of the corner portions of the plate-like body through the insertion holes. Next, after the next plate-like body is overlaid on the plate-like body arranged in advance, the left and right side surface upper surface portions are folded along the crease with respect to the left and right side surface portions and are covered on the upper surface of the plate-like body. Further, the back side upper surface part is folded along the crease to cover the upper surface of the plate-like body with respect to the back surface part, and the front side upper surface part is folded along the crease with respect to the front part to cover the upper surface of the plate-like body. .

  As a result, by partitioning the partitioning pieces on the back surface and the front surface, the left and right side surfaces, the back surface, and the front surface It is possible to support the upper and lower plate-like bodies by buffering them at the corners through the large-area partitioning pieces regardless of the height, so that the upper and lower plate-like bodies are sure to contact each other. Can be prevented.

  According to the present invention, when a plate-like body such as a solar cell module with a mold is stacked on top and bottom, the corner portions of the upper and lower plate-like bodies are supported while being buffered by a large-area partition piece. be able to.

The insertion hole 4 a is formed corresponding to the locking piece 10. Further, a convex cut g such as a U-shape is formed on the side surface side upper surface portion 4 in the vicinity of each of the upper and lower ends facing each insertion hole 4 a described above toward the fold line b with the side surface portion 3. In addition, a pair of cuts h, h perpendicular to the side edge across the convex cut g are formed from the side edge over a set length, and these convex cut g and the convex cut Between the pair of cuts h and h sandwiching g, from each edge of the convex cut g toward each cut h, and from the terminal edge of each cut h toward the convex cut g, A pair of parallel folds i and i are formed at an interval corresponding to the thickness of the inner flange portion p1b of the frame p1 constituting the plate-like body P.

  In this case, the distance from the fold line b to the inward fold line i between the side surface part 3 and the side surface side upper surface part 4 is set to the width of the inner flange part p1b.

  These convex cuts g, a pair of cuts h, h, and a pair of parallel folds i, i form a retaining piece 41 and a bounce preventing piece 42 continuous to the retaining piece 41 as will be described later. .

  In addition, the fold line a between the bottom surface part 2 and the side surface part 3 is intermittently formed at a set interval, and the bottom surface part 2 is connected to a terminal edge and a start edge facing each other in the intermittent fold line a. A square bracket-shaped cut j is formed. On the other hand, the fold line b between the side surface portion 3 and the side surface side upper surface portion 4 is also formed intermittently at a set interval, and the side surface side upper surface portion 4 has an end edge and a starting end facing each other in the intermittent fold line b. A square bracket-like cut k is formed by connecting the edges. In this case, the square bracket-shaped cut j formed in the bottom surface portion 2 and the square bracket-shaped cut k formed in the side surface upper surface portion 4 are alternately formed.

  Similarly, the crease c between the bottom surface portion 2 and the back surface portion 5 and the crease c between the bottom surface portion 2 and the front surface portion 6 are also formed intermittently at a set interval, and the bottom surface portion 2 has an intermittent A square bracket-like cut m is formed by connecting the opposite end edge and start edge of the fold c. Further, the fold line d between the back surface part 5 and the back surface side upper surface part 7 and the fold line d between the front surface part 6 and the front surface side upper surface part 8 are also formed intermittently at set intervals, and the back surface side upper surface part 7 and On the front-side upper surface portion 8, square bracket-shaped cuts n are respectively formed by connecting opposing end edges and start edge edges in the intermittent folds d. In this case, the square bracket-shaped cut m formed on the bottom surface portion 2 and the square bracket-shaped cut n formed on the back side upper surface portion 7 are formed alternately, and the square bracket-shaped cut formed on the bottom surface portion 2 is formed. The cuts m and the square bracket-like cuts n formed on the front side upper surface portion 8 are formed alternately.

  By these square bracket-like cuts j, k, m, and n, as described later, the upper and lower edges of the side surface portion 3, the upper and lower edges of the back surface portion 5, and the upper and lower edges of the front surface portion 6, respectively. Alternating legs 31, 51, 61 projecting upward and downward are formed.

  On the other hand, a crease q having a set length is formed on the back surface portion 5 and the front surface portion 6 so as to be located outward by a height corresponding to the thickness of the cardboard with respect to the intermediate line that bisects the height. The U-shaped cut r is formed so as to partially overlap the crease c with the bottom surface portion 2 by connecting the respective edges of the fold q.

  The folds q and the U-shaped cut r form partition pieces 52 and 62 between the plate-like bodies P and P that are stacked one above the other as described later.

  Further, the partition portion 9 connected to the back surface portion 5 includes a cut s having a set length that extends downward from the upper end edge perpendicular to the upper end edge at the outer corner portion, and the side end edge. A partition piece 91 is defined by a crease t extending perpendicularly from the side edge toward the rear edge 5 of the cut s. Similarly, the partition 9 connected to the front surface 6 also has a cut s having a set length extending from the lower edge to the upper side perpendicular to the lower edge at the outer corner, and the side edge. A partition piece 91 is defined by a fold t extending perpendicularly to the edge and extending from the side edge toward the front edge 6 of the cut s. In addition, the side edge of each partition portion 9 is notched with a width slightly larger than the cardboard thickness until the crease t of the partition piece 91 exceeds the length slightly larger than the cardboard thickness. A locking portion 91a of the partition piece 91 is formed by the notched portion. Further, the partitioning portion 9 includes a crease e between the partitioning portion 9 and the back surface portion 5, a corner portion defined by an extension line of the fold line d between the back surface portion 5 and the back surface side upper surface portion 7, and the partitioning portion 9. At the corner defined by the crease e between the front part 6 and the crease d between the front part 6 and the front side upper surface part 8, and a partition part 9. A substantially right-angled triangular notch 9a is formed by the cuts connecting the end edges of the cuts from the upper and lower end edges. As will be described later, when the engaging piece 10 is inserted into the insertion hole 4a, the end portions of the back surface portion 5 and the front surface portion 6 are elastically deformed by the depth of the notch portion 9a. It is set to be possible.

  Here, the width of the partition piece 91 of the partition part 9 and the length of the insertion hole 3a are the same, and the fold line e between the partition part 9 and the back surface part 5 (front surface part 6) and the break s of the partition part 9 are shown. The space between the two is obtained by adding the width of the locking portion 91a of the partition portion 9 to the length from the extension line of the crease c between the bottom surface portion 2 and the back surface portion 5 (front surface portion 6) to the outer edge of the insertion hole 3a. Approximate length. That is, as will be described later, when the partition piece 91 of the partition portion 9 is inserted into the insertion hole 3a, the engagement is still between the inner surface of the back surface portion 5 (front surface portion 6) and the upper and lower end edges of the side surface portion 3. There is room to push in the width of the stop portion 91a.

  Further, the back-side upper surface portion 7 and the front-side upper surface portion 8 are provided with the above-described convex cut g, a pair of cuts h, h, and a pair of parallel folds i, i, and a retaining piece 41 and a splash prevention piece. The height 42 can be covered from above. That is, the length from the crease d between the back surface portion 5 and the back surface side upper surface portion 7 to the upper edge of the back surface side upper surface portion 7 is from the upper edge of the side surface side upper surface portion 4 to the retaining piece 41 and the jumping up near the upper edge portion. It is set to be larger than the length to the lower cut line h that forms the prevention piece 42. Similarly, the length from the crease d between the front surface portion 6 and the front surface upper surface portion 8 to the lower end edge of the front surface upper surface portion 8 is from the lower edge of the side surface upper surface portion 4 to the retaining piece 41 in the vicinity of the lower end portion. It is set to be larger than the length to the upper cut line h that forms the spring-up preventing piece 42.

  Further, the locking piece 10 connected to the back side upper surface part 7 includes a locking groove having a width and depth slightly larger than the thickness of the cardboard along the fold line f with the back side upper surface part 7 at the upper edge. 10a is formed. Similarly, the locking piece 10 connected to the front side upper surface portion 8 also has a width and depth that is slightly larger than the thickness of the cardboard along the fold line f with the front side upper surface portion 8 at the lower end edge portion. A groove 10a is formed.

  Here, the height of the locking piece 10 and the length of the insertion hole 4a coincide with each other, and the length from the fold line d between the back surface portion 5 and the back surface side upper surface portion 7 to the lower end edge of the locking piece 10 ( The length from the crease d between the front face 6 and the front face upper face 8 to the upper edge of the locking piece 10 is the length from the upper edge of the side face upper face 4 to the upper edge of the upper insertion hole 4a. The length is set to be slightly larger than the length obtained by adding the depth of the locking groove 10a to the length from the lower end edge of the side surface upper surface portion 4 to the lower end edge of the lower insertion hole 4a. That is, as will be described later, when the locking piece 10 is inserted into the insertion hole 4 a, the locking groove 10 a is still between the inner surface of the back surface portion 5 (front surface portion 6) and the upper and lower end edges of the side surface portion 3. A margin to push in as much as the depth is secured.

  In addition, since the notch part 9a is formed in the partition part 9, the edge part in the vicinity of the crease d with the back side upper surface part 7 (front side upper surface part 8) of the back surface part 5 (front surface part 6) is elastically deformed. Thus, the locking piece 10 can be easily inserted into the insertion hole 4a.

  Next, the case where the solar cell module with a formwork which is the plate-shaped body P is packed using the packing material 1 comprised in this way is demonstrated based on FIG. 4 thru | or FIG.

  First, after packing material 1 is punched according to each development view, two packing materials 1 and 1 are arranged symmetrically on the work table with an interval corresponding to the width of plate-like body P. Specifically, at the four corners of the plate-like body P, the intersection of the crease a between the bottom surface portion 2 and the side surface portion 3 and the crease c between the bottom surface portion 2 and the back surface portion 5 in the left and right packing materials 1, 1, bottom surface portion The left and right packing materials 1 and 1 are arranged on the work table so that the intersections of the crease a between the side surface portion 3 and the crease c between the bottom surface portion 2 and the front surface portion 6 face each other (see FIG. 4). .

  Next, after placing the plate-like body P over the bottom surface portions 2 and 2 of the left and right packing materials 1 and 1 disposed opposite to each other (see FIG. 5), the back surface portion 5 and the front surface portion 6 are attached to the bottom surface portion 2. It folds along the crease c and rises along the back and front of the plate-like body P. At this time, the partition pieces 52 and 62 are protruded inward by pushing the portions defined by the U-shaped cuts r of the back surface portion 5 and the front surface portion 6 inward from the outside, and the plate-like body P (See FIG. 6). Furthermore, the side surface portion 3 is valley-folded along the crease a with respect to the bottom surface portion 2, and is raised along the left and right side surfaces of the plate-like body P (see FIG. 7).

  Thereafter, the partition piece 91 of each partition portion 9 is valley-folded along the fold line t, and the partition portion 9 is valley-folded along the fold line e with respect to the back surface portion 5 and the front surface portion 6, respectively. It inserts in the insertion hole 3a of the corresponding side surface part 3, respectively. Thereby, the partition piece 91 is mounted on the upper surface of the position close | similar to the corner part of the plate-shaped body P (refer FIG. 8, FIG. 9). At this time, when the partition piece 91 is inserted into the insertion hole 3a, the intermediate portion in the height direction of the side surface portion 3 is engaged between the inner surface of the back surface portion 5 (front surface portion 6) and the front and rear end edges of the side surface portion 3. A gap substantially corresponding to the width of the stop portion 91a is formed. Therefore, by pushing the back surface part 5 (front surface part 6) so that the inner surface thereof is in contact with the front and rear edges of the side surface part 3, the back surface part 5 (front surface part 6) rotates around the crease c with the bottom surface part 2. And the clearance gap substantially equivalent to the width | variety of the latching | locking part 91a is closed in the height direction intermediate part of the side part 3. FIG. That is, the partition part 9 connected to the back face part 5 (front face part 6) is pushed inward along the outer surface of the side face part 3, and the locking part 91a is the edge of the insertion hole 3a of the side face part 3. Locking to the inner surface prevents the partition piece 91 from coming out of the insertion hole 3a.

  Thus, if the partition pieces 52, 62, 91 are arranged on the upper surface of the plate-like body P, the side plate 3 is overlapped on the plate-like body P previously placed on the next plate-like body P, On the other hand, the side-side upper surface portion 4 is valley-folded along the fold line b so as to be along the inner flange portion p1b of the frame p1 constituting the plate-like body P (see FIG. 10B), and the side-side upper surface portion 4 The inner flange portion of the frame p1 in the plate-like body P of the pair of folds i and i parallel to the portion (the retaining piece 41) defined by the pair of cuts h and h formed in the vicinity of the upper and lower ends of the plate A valley fold is performed along the fold line i on the side surface portion 3 side corresponding to the edge of p1b. At this time, the portion (bounce prevention piece 42) defined by the convex cut g is raised in conjunction with the retaining piece 41 (see FIG. 10C). Further, the retaining piece 41 defined by the pair of cuts h and h is folded inward along another fold line i and wound around the inner flange portion p1b. At this time, the jump-up preventing piece 42 partitioned by the convex cut g is projected toward the distal end side (inward side of the plate-like body P) of the side surface side upper surface portion 4 in conjunction with the retaining piece 41 ( (Refer FIG.10 (d), FIG.11, FIG.12).

  Next, the locking piece 10 is valley-folded along the fold line f with respect to the back surface side upper surface portion 7, and the back surface side upper surface portion 7 is valley-folded along the fold line d with respect to the back surface portion 5. The locking piece 10 is inserted into the insertion hole 4 a of the side surface upper surface portion 4. In this case, when the locking piece 10 is inserted into the insertion hole 3 a, the depth of the locking groove 10 a is formed between the inner surface of the back surface portion 5 and the rear end edge of the side surface portion 3 at the height position of the side surface upper surface portion 4. In a state where a gap substantially corresponding to this is formed, the end edge of the locking piece 10 interferes with the inner peripheral edge of the insertion hole 4a, and subsequent insertion is prevented. That is, since the partition piece 91 is inserted into the insertion hole 3a of the side surface portion 3, the rotation of the back surface portion 5 where the partition portion 9 is continuously provided around the crease c with the bottom surface portion 2 is restricted. Yes. For this reason, using the notch 9a of the partitioning part 9, the upper end edge of the back part 5 is slightly elastically deformed so as to rotate outward, and in this state, the locking piece 10 is inserted into the insertion hole 4a. Plug in. Thereafter, the back surface portion 5 is pushed so that the inner surface thereof is in contact with the rear end edge of the side surface portion 3, whereby the back surface portion 5 is rotated around the crease c with the bottom surface portion 2, and the depth of the locking groove 10a is reached. A substantially corresponding gap is closed. That is, the locking piece 10 connected to the back surface upper surface portion 7 is pushed inward along the inner surface of the side surface portion 3 while being inserted into the insertion hole 4a, and the locking groove 10a is formed on the side surface. It is latched by the edge part of the insertion hole 4a of the side upper surface part 4, and the withdrawal of the latching piece 10 from the insertion hole 4a is prevented.

  As a result, the back-up prevention piece 42 is pressed from above by the back-side top surface portion 7 defined by the convex cuts g formed on the side-side top surface portion 4, and the splash-up prevention piece 42 is formed into a pair of parallel folds i and i. The locking groove 10a of the locking piece 10 is locked to the side surface upper surface portion 4, and the locking piece 10, that is, the rear surface side upper surface portion 7 is creased d. (See FIGS. 1 and 2).

  Similarly, the locking piece 10 is valley-folded along the fold line f with respect to the front side upper surface part 8, and the front side upper surface part 8 is valley-folded along the fold line d with respect to the front part 6 to form a plate-like body. While bend | folding so that the upper surface of P may be followed, the latching piece 10 is inserted in the insertion hole 4a of the side surface upper surface part 4. As shown in FIG. At this time, as described above, the upper end edge portion of the front portion 6 is slightly elastically deformed using the notch portion 9a of the partition portion 9 so as to rotate outward, and the locking piece 10 is moved in this state. Insert into the insertion hole 4a. Thereafter, the front portion 6 is pushed so that the inner surface thereof is in contact with the front end edge of the side surface portion 3, whereby the front portion 6 rotates around the crease c with the bottom surface portion 2, and the depth of the locking groove 10 a is substantially reduced. The corresponding gap is closed. That is, the locking piece 10 connected to the front side upper surface portion 8 is pushed inward along the inner surface of the side surface portion 3 in a state where the locking piece 10 is inserted into the insertion hole 4a, and the locking groove 10a is formed on the side surface. It is latched by the inner and outer surfaces of the edge of the insertion hole 4a of the side upper surface portion 4, and the locking piece 10 is prevented from coming off from the insertion hole 4a.

  As a result, the front-side upper surface portion 8 presses the jump-up preventing piece 42 defined by the convex cut g formed on the side-side upper surface portion 4 from above, and the jump-up preventing piece 42 is formed into a pair of parallel folds i and i. And the locking groove 10a of the locking piece 10 is locked to the side surface upper surface portion 4, and the locking piece 10, that is, the front surface upper surface portion 8 is creased d. (See FIGS. 1 and 2).

  As a result, when the two plate-like bodies P, P stacked one above the other are packed with the packing materials 1, 1, the retaining piece 41 of the packing material 1 is in the plate-like body P as shown in FIGS. 1 and 2. While being wound around the inner flange portion p1b of the frame p1, the back-side upper surface portion 7 and the front-side upper surface portion 8 are respectively covered from the upside by the bounce-preventing piece 42 integral with the retaining piece 41, and the bounce-off preventing piece 42 is in the original position. While preventing the return, each locking piece 10 is inserted into the insertion hole 4a formed on the side surface 4 and the locking groove 10a is locked to the side surface 4 and By preventing the stop piece 10 from coming out, that is, preventing the back side upper surface portion 7 and the front side upper surface portion 8 to which the respective locking pieces 10 are continuously provided from returning to their original positions, Detachment of packing material 1 It is possible to really prevent. Therefore, it is not necessary to bind the two packing materials 1 and 1 facing left and right with a binding band or the like, so that the packing operation can be performed in a short time, and the increase in cost can be suppressed.

  Moreover, since the upper and lower plate-like bodies P and P packed by the packing material 1 are supported in the buffer state via the partition pieces 91 having a large area at the corners, the upper and lower plate-like bodies P and P are Contact can be reliably prevented. That is, by providing the partition portion 9 that partitions the partition piece 91 on each of the back surface portion 5 and the front surface portion 6, the cardboard can be molded regardless of the height of the side surface portion 3, the back surface portion 5, and the front surface portion 6. Since the partition piece 91 having a large area within the range (if necessary, the partition piece 91 having an arbitrary size can be formed ignoring the molding efficiency), the corners of the upper and lower plate-like bodies P, P can be formed. The corner portion can be supported while being buffered by the partitioning piece 91 having a required size.

  Further, a plurality of leg portions 31, 51, 61 by square bracket-like cuts j, k, m, n protrude from the lower surface of the bottom surface portion 2 at the lower end edges of the side surface portion 3, the back surface portion 5, and the front surface portion 6, respectively. A plurality of leg portions 31, 51, 61 by square bracket-like cuts j, k, m, n at the upper end edges of the side surface portion 3, the back surface portion 5, and the front surface portion 6 are the upper surface of the side surface side upper surface portion 4, and the rear surface side. It is formed so as to protrude from the upper surface of the upper surface portion 7 and the upper surface of the front surface upper surface portion 8. The leg portions 31, 51, 61 projecting from the lower surface of the bottom surface portion 2, the upper surface of the side surface side upper surface portion 4, the upper surface of the rear surface side upper surface portion 7, and the leg portions 31, 51, 61 is formed alternately. Thereby, when the plate-like bodies P and P packed by the packing materials 1 and 1 are piled up and down, the leg part 31 which protrudes from the bottom face part 2 of the packing materials 1 and 1 which pack up the upper plate-like bodies P and P. , 51, 61 are leg portions 31, 51 projecting from the side-side upper surface portion 4, the rear-side upper surface portion 7, and the front-side upper surface portion 8 of the packing material 1, 1 for packing the lower plate-like bodies P, P, respectively. , 61 can be grounded, and the upper and lower packing materials 1, 1 can be positioned in the left-right direction and the front-rear direction and supported so as not to move.

  At this time, the retaining piece 41 formed on the side surface upper surface portion 4 wraps around the inner flange portion p1b of the plate-like body P, and the packaging material 1 is prevented from coming off with the jumping-up preventing piece 42 and is assembled. , 51, 61 can be made extremely high in positional accuracy. Therefore, even if the packing material 1 is divided into two left and right members, the legs 31, 51 and 61 can be very easily aligned when stacked up and down, and the lateral displacement phenomenon when stacked vertically is reduced. Occurrence can be greatly suppressed.

  In the above-described embodiment, the solar cell module with a mold is illustrated as the plate-like body P. However, not only the solar cell module with a mold but also a window frame, a door frame, and the like are packed as a plate-like body. Can do.

In addition to the left and right side surfaces facing each other in the short direction, the bottom surface, top surface, front surface, and back surface near the left and right side surfaces can be covered.

  Moreover, it is not restricted to the form provided with the packing materials 1 and 1 facing the left and right side surfaces of the plate-like body P, for example, as shown in FIG. 13, the back surface portion 5 and the back surface upper surface portion 7, the front surface portion 6 and the front surface. The left and right packing materials 1 and 1 may be integrally provided continuously by part (or all) of the side upper surface portion 8 and the bottom surface portion 2. According to such a packing material, the back surface and the front surface of the plate-like body P can be simultaneously protected by the packing material.

  Further, prior to punching the packing material 1 in accordance with the development view, the portion of the side face 3 facing the insertion hole 4a (the portion indicated by hatching in the development views of FIGS. Is preferably thinned. Thereby, the locking piece 10 can be easily inserted into the insertion hole 4a.

  Furthermore, when the locking piece 10 is inserted into the insertion hole 4a, a notch 9a is formed in the partitioning part 9 to allow elastic deformation of the upper edge portions of the back part 5 and the front part 6, but the notch part 9a However, the elastic deformation of the upper edge portions of the back surface portion 5 and the front surface portion 6 may be allowed only by a break along the fold line e.

  In addition, a locking piece 10 is connected to each of the back-side upper surface portion 7 and the front-side upper surface portion 8, and an insertion hole 4 a is formed in the side surface-side upper surface portion 4 corresponding to the locking piece 10. The case where the back side upper surface portion 7 and the front side upper surface portion 8 are prevented from jumping up by being inserted and locked in the insertion hole 4a has been described. 7 and the front side upper surface part 8 may be adhered to the side surface side upper surface part 4 using an adhesive tape or the like.
