It may be formed in a slightly wide oblique line along the diagonal line. In addition, the bracing portion may be formed in various shapes such as being provided in a curved line instead of being linear as long as it is provided so as to connect the corner portions of the window frame portion.

  In the illustrated example described above, the reinforcing structure is provided with the brace 30 on the article placement surface b of the lower inner box C. However, as with the lower inner box C, for example, as shown by the chain line in FIG. The upper inner box B may have a reinforcing structure in which a brace 40 is formed along the diagonal line of the window frame 24 on the article pressing surface a, and the synthetic resin film 25 is bonded to the window frame 24. it can. In this other example, even if the delivery box is carried or delivered in a direction that is flipped upside down by mistake, the upper inner box B retains the strength against the pulling external force as described above. In this state, the heavy article delivery article P can be stably held between the synthetic resin films 25 and 35.

  Further, according to the present invention, as shown in FIG. 8, for example, as shown in FIG. A configuration in which the joint portions 45 and 45 are provided is preferable. When the lower inner box C is fitted into the outer box A at the time of assembly, the lid piece engaging portions 45 and 45 are formed so that the lower edge portion of the opposed side plate portion 27 is engaged with the upper lid pieces 14a and 14a on the bottom surface. The upper lid pieces 14a and 14a are cut out into shapes corresponding to the length and plate thickness. Then, when the lower inner box C is fitted into the outer box A at the time of assembly, both side edges of the upper lid pieces 14a and 14 are engaged with these lid piece engaging portions 45 and 45. The opposing side surface plate portion 27 can be positioned along the opposing side plate 11 of the outer box A without being bent, and the lower inner box C can be prevented from being erroneously fitted into the outer box A in a buckled state.

  Now, in the article delivery box of the first example described above, each of the upper and lower inner boxes B and C is divided into four pieces of side plate parts 20 which are separated by providing cuts between the side plate parts adjacent to each other. -It consisted of 21, 27, 28. However, the article delivery box according to the present invention is formed by bending the upper and lower inner boxes B and C without separating the adjacent side plate parts as described in the second example of the best mode described below. Corners may be provided at the four corners, thereby forming an integral rectangular frame shape as a whole, and a structure in which reinforcing portions are attached to the corners may be provided.

Cuts 50 are formed obliquely along the diagonal line b, that is, along the brace 30. Then, as shown in FIG. 12, the side plate portions 46 are formed in four directions by bending along the folds 44, and the adjacent side plate portions are folded inward along the cuts 50, that is, folds are formed. Folding is performed inwardly along the brace 30 to form corners 51 at the four corners, and the whole is shaped like a shallow rectangular box open on one side.

  Therefore, as shown in FIG. 13, when the lower inner box C is fitted into the outer box A with the article placement surface b facing upward, the lower inner box C is Constrained by the four-side plate portions 10 and 11 of the box A and folded along the folds 44 and the notches 50, triangular bent plate pieces 55 a and 55 a are formed at the corner portions 51 with the folds of the notches 50 as fulcrums. A reinforcing part 55 is formed which is folded in the pressed state. Further, when the upper inner box B is fitted so that the article pressing surface a overlaps with the article placement surface b of the lower inner box C, the upper inner box B is similarly restrained by the four side plates 10 and 11 of the outer box A. Then, the reinforcing portions 56 are folded along the folds 37 and the notches 40, and are folded in a state where the triangular bent plate pieces 56a and 56a are pressed against each corner portion 41 with the folding mountain of the notches 40 as a fulcrum. It is supposed to be formed. Then, while folding the inner lid pieces 15a of the outer box A inward along the folds x, y, and z of the first bent portion 17 as shown in FIG. It is placed on the reinforcing portion 56 of the inner box B, the tip piece 19a side is overlaid, and the outer lid piece 15b is folded over and placed on the left and right side walls 16 for assembly. At the time of this assembly, the article delivery box receives and supports the shelf 19 by the reinforcing portion 56 of the upper inner box B when the inner lid piece 15a is folded and closed, and the outer lid piece 15a is supported on the inner lid piece 15a. When 15b is folded, an accessory storage portion R is formed between the inner lid piece 15a and the outer lid piece 15b.

  In the article delivery box of the second example, when the article P is packed, the lower inner box C is placed in the outer box A with the article placement surface b facing upward in the outer corner A as in the case of the illustrated example. After each reinforcing part 55 is fitted to a depth position where it is placed on the bottom plate part 14, the delivery article P is placed on the synthetic resin film 35 on the article placement surface b, and then the article pressing surface a is directed downward. After the upper inner box B is fitted so as to cover the article P with the synthetic resin film 25, the inner lid piece 15a of the outer box A is closed while pressing the upper inner box B downward. If there is an accessory, place the accessory on the inner lid piece 15a, fold the outer lid piece 15b and close the accessory storage section R, and finally close the outer box with an adhesive tape (not shown). Seal A. As a result, the delivery article P is restrained and held without moving in the state of being sandwiched between the synthetic resin films 25 and 35 of the upper and lower inner boxes B and C in the hollow portion in the outer box A, Even if a vibration or impact is applied to the box A, the external force is packed by the upper and lower inner boxes B and C so as to be protected.

  Therefore, in the delivery box of the second example, in such a packaged state of the article, the lower inner box C is placed with the synthetic resin film 35 stretched over the integral window frame part 29 and the brace part 30. The surface b is formed, and the heavy load of the article P is supported not only by the synthetic resin film 35 and the window frame portion 29 but also by the brace portion 30 connected to the reinforcing portion 55 of the four corner portion 51 that is particularly strong. Since it is a structure, the synthetic resin film 35 is bent according to the weight of the article P and the article P is prevented from sinking excessively by the brace 30, and a strong vibration or impact may be applied. In addition, the weight of the article P attenuates the force with which the window frame portion 29 is pulled by the synthetic resin film 35, and thereby the article P of the heavy article is kept in the state where the strength against the pulling external force is always maintained in the lower inner box C. Between the synthetic resin films 25 and 35 It can be pressure retaining. In addition, in the delivery box of the other example shown in the figure, the upper inner box B that holds the article P with the synthetic resin film 25 is also configured to increase the strength by forming the reinforcing portions 56 at the four corner portions. Even if the window frame portion 23 is pulled by the synthetic resin film 25 due to the weight of the article P due to vibration or impact, it is supported by the reinforcing portions 56 at each corner and the upper inner box B is also strong against tensile force. As a result, the heavy article P can be held between the synthetic resin films 25 and 35 more stably.

  Further, in the second example, the lower inner box C of the article delivery box is a four-corner corner portion 51 having a reinforcing portion 55 without separating adjacent side plate portions 46 as shown in FIG. When it is shaped into an integral rectangular frame and fitted into the outer box A, each reinforcing portion 55 is placed on the bottom plate of the outer box A to support the entire rectangular frame. The face plate portion 46 can be securely and smoothly fitted into the outer box A without buckling inward.

The third example shows a modification in which a part of the outer box A of the first example and a part of the upper and lower inner boxes B and C of the second example are improved. Therefore, in the third example, the same reference numerals are given to the same components as those in the first and second example goods delivery boxes illustrated above, and the following description will be given.

  As shown in FIG. 15, the outer case A of the third example includes a pair of inner lid pieces 15 a each having a first bent portion 17 and a shelf plate portion 19 on the front end side thereof, and each first folding portion The bent portion 17 is provided with three fold lines x, y, and z that are parallel to each other so that the first bent portion 17 is folded downward in a U-shaped cross section. On the vertical plate surface 17a formed between the two folds y and z, the abutting piece 17c having a length corresponding to the width of the lid receiving surface 17b formed between the two folds x and y on the opposite side is provided. It is the structure which formed the notch hole 60 leaving. Further, the inner lid piece 15a is formed to have a length in which the front end pieces 19a of the shelf plate portions 19 overlap each other when the first bent portion 17 is folded inward. A handle recess 19b cut out for the handle is provided.

  The upper inner box B of the third example is similar to the upper inner box B of the second example described above, as shown in FIG. 16, for example, a crease 37 along the four-side outer edges of one rectangular cardboard. A rectangular object pressing surface a having a size matching the rectangular opening S of the outer box A is formed by being surrounded by the fold 37, and the cross-shaped fold 37 is formed from the four corner edges 40a. Incisions 40 are provided obliquely between the intersection points 40b and along the diagonal lines of the article pressing surface a. Therefore, as shown in FIG. 17, when bending along the crease 37, the side plate portions 61 and 62 are formed in four directions, and the space between the adjacent side plate portions 61 and 62 is formed along the notch 40. When folded in the direction, that is, when the fold mountain is folded inwardly along the diagonal line of the article pressing surface a, the corner portion 41 where the triangular folding plate pieces 41a and 41b are folded at the four corners with the fold mountain of the cut 40 as a fulcrum. Is formed, and as a whole, is folded into a shallow rectangular box open on one side.

  In addition, the upper inner box B of the third example is different from the upper inner box B of the second example, as shown in FIG. The small trapezoid 65 having a substantially trapezoidal shape that gradually becomes wider is formed to be freely bent and raised. On the other hand, the side plate 61 on the short side adjacent to the other side triangular bent plate piece 41b is formed with a hole-shaped receiving hole 66 adapted to the outer shape so that the fastening piece 65 can be fitted. . Further, as shown in FIG. 17, the upper inner box B of the third example is folded in a triangular shape so that the corner portion 41 is lower than the side plate portions 61 and 62 when folded and assembled into a rectangular box shape. The curved plate pieces 41a and 41b are partially cut to form a triangular shape that is one step smaller. The side plate 62 on the long side is also provided with a stopper piece 20a for assisting in receiving the shelf 19 of the inner lid piece 15a.

  Therefore, after the upper inner box B of the third example is folded up into a rectangular box shape, as shown in FIG. 18, when a fastening piece 65 is fitted into the receiving hole 66 as a connecting means, adjacent triangular bent plates The pieces 41a and 41b are joined so as not to open apart from each other, and a rectangular box shape is maintained. Thereby, in the upper inner box B, the reinforcing portions 56 are formed in advance in each corner portion 41 so as to be folded in a state in which the triangular bent plate pieces 41a and 41b are in pressure contact with the folding mountain of the cut 40 as a fulcrum. ing.

  Next, as shown in FIG. 19, the lower inner box C of the third example is folded like a grid along the four-side outer edges of one rectangular cardboard as shown in FIG. A rectangular article placement surface b having a size corresponding to the rectangular opening S of the outer box A is formed by being provided with eyes 44 and surrounded by the folds 44, and the cross-shaped folds are formed from the four corners 50a. The diagonal cuts 50 are provided between the intersections 50b of 44 and diagonal lines of the article placement surface b, that is, along the brace 30. Then, as shown in FIG. 20, when bent along the fold 44, the side plate portions 68 and 69 are formed in four directions, and the adjacent side plate portions 68 and 69 are inward along the notch 50. When the folds are folded inward, that is, when the folds are folded inwardly along the brace 30, the corners 51 are formed at the four corners where the folding plate pieces 51a and 51b are folded with the folds of the cuts 50 as fulcrums. It is designed to fold up into a shallow rectangular box that is open on one side.

  In addition, the lower inner box C of the third example is different from the lower inner box C of the second example, as shown in FIG. 19, with a cut at the upper edges of the triangular bent plate pieces 51a and 51b. A pair of hooking pieces 70 and 71 that are gradually wider toward the tip are formed to be foldable. Therefore, the lower inner box C of the third example is folded into a rectangular box shape, and as shown in FIG. 21, as the connecting means, the latching pieces 70 and 71 are overlapped and folded in the same direction. When the upper latching piece 70 is latched in the notch hole 75 formed in the trace where the latching piece 71 is folded, the adjacent triangular folding plate pieces 51a and 51b are prevented from opening apart from each other. They are combined to maintain a rectangular box shape. Thereby, in the lower inner box C, a reinforcing portion 55 is formed in advance in each corner portion 51 so as to be folded in a state in which the triangular bent plate pieces 51a and 51b are pressed against each other with the folding mountain of the cut 50 as a fulcrum. ing.

  In the article delivery box of the third example having the above-described configuration, when the article P is packed, when the lower inner box C is fitted into the outer box A with the article placement surface b facing upward, the lower inner box C The upper hooking piece 70 is hooked in the notch hole 75, and the triangular bent plate pieces 51a and 51b are joined in advance so as not to open at each corner portion 51, so that the rectangular box shape is maintained. Therefore, it is possible to easily fit into the lower part of the outer box A through the opening of the outer box A smoothly as shown in FIG.

Box B is fitted into outer box A. When the upper inner box B is fitted into the outer box A, the upper inner box B is fitted with the retaining piece 65 in the receiving hole 66 so that the triangular bent plate pieces 41a and 41b are preliminarily formed at each corner portion 41. Since the rectangular box shape is maintained by being joined so as not to be opened, it can be easily fitted into the outer box A through the opening of the outer box A smoothly without hooking a part thereof.

  Thereafter, while folding the inner lid piece 15a of the outer box A inward along the folds x, y, and z of the first bent portion 17, the shelf portions 19 are alternately tilted, and the tip piece 19a side is The opening of the outer box A is closed by overlapping. Then, as shown in FIG. 23, the inner lid piece 15a has the abutting piece 17c abutting against the opposing side plate portions 10 and 10 of the outer casing A at the first bent portion 17, and the shelf plate portion between the opposing side plate portions. A rack-like posture in which 19 is stretched horizontally is maintained. And when there is an accessory, place the accessory on the shelf 19 of the inner lid piece 15a, then fold the outer lid piece 15b and place it on the left and right lid receiving surfaces 17b. The accessory storage portion R between the outer lid pieces 15b is closed. Thus, similarly to the second example, in the hollow portion in the outer box A, the upper and lower inner boxes B. Even when strong vibration or impact is applied to the outer box A, the outer force is applied to the upper and lower inner boxes B and C while being held between the C synthetic resin films 25 and 35 without being displaced. Pack it so that it can be buffered and protected.

  By the way, in the above 3rd example, in order to maintain the shape of a rectangular box shape by connecting the upper inner box B so that the triangular bent plate pieces 41a and 41b do not open at the respective corner portions 41, As in the lower inner box C, the triangular bent plate pieces 41a and 41b of each corner portion 41 can be connected by connecting means for hooking the upper hooking piece 70 in the notch hole 75. On the contrary, in order to maintain the rectangular box shape by connecting the lower inner box C so that the triangular bent plate pieces 51a and 51b do not open at each corner 51, the upper inner box B is The triangular bent plate pieces 51a and 51b of each corner portion 51 can be connected by connecting means for fitting the retaining piece 65 into the receiving hole 66.
