Description

  The present invention relates to a structure of a packaging box in which at least a part of an article is covered with a buffer and accommodated in a box-shaped packaging body, and is particularly suitable for an electronic device and a precision device such as a printer, a facsimile machine, and a laptop computer. It relates to packaging boxes.

Conventionally, when shipping various articles such as electronic equipment and precision equipment produced in a factory, the goods are packed in a box-shaped packing body such as a cardboard box, For the purpose of buffering impacts and loads received from the outside during transport and storage, articles are partially wrapped in a buffer and stored in a package. In recent years, considering the reduction of plastic waste such as polystyrene foam as much as possible and the promotion of recycling, the use of a buffer made of pulp mold made of waste paper is increasing (see Patent Document 1).
JP 2007-131307 A (see FIG. 1)

  The pulp mold cushioning body is made of waste paper, and many irregularities are formed on the inner and outer surfaces of the thin-walled open box-shaped member. A protrusion is provided corresponding to the outer shape of the article, and a protrusion is provided on the outer side of the buffer body corresponding to the inner shape of the package. However, considering the draft at the time of molding, the protrusion of the buffer has a tapered shape that tapers toward the outside. In addition, in the cushioning part facing the corners and ridges of the package (where two or more surfaces of the package intersect), the protrusions that support the corners and ridges of the package sufficiently Because it is difficult to make, the buffer performance tends to be insufficient.

  For this reason, when the packing body receives a load from the outside due to dropping or impact, the cushioning body at a portion corresponding to the corner or ridge line portion of the packing body easily deforms together with the packing body, which may cause damage to the article.

  The present invention relates to a packaging box that accommodates an article in a box-shaped packaging body together with a cushion that covers a part of the article, and in particular, reinforces corners and ridges of the packaging body to improve the cushioning property against the article. It is the purpose.

In order to achieve the object, the invention according to claim 1 is a box-shaped packing body that stores an article to be packed, and a buffer body that covers at least a part of the article and is stored in the packing body. The packaging body is formed in a box shape by bending a sheet material, and the sheet material is first on the side plate portion constituting the outer surface of the packaging body. And at least an inner piece that is bent along a second direction perpendicular to the first direction on the inner side of the packing body, and the packing body includes four side plate portions and 1 The side plate portion, which is formed in a rectangular tube shape with one sheet material connected to one of the inner pieces along the first direction, is located at the end of the side where the inner pieces are not connected. The side plate portion located on the side where the inner pieces are connected to each other Others are fixed to the inner piece, the tip of the inner piece, out at the inside of the package of the four side plate portions, is fixed to the side plate portion adjacent to the side plate portion in which the inner member is connected, On the inner side of the packing body, the inner piece is bent to form an inner wall portion that is arranged with a space from the side plate portion and abuts against the buffer body, and the buffer body is made of a pulp mold. A plurality of protrusions are formed for buffering, and an inner wall portion formed of the inner piece is partially provided with a tongue piece portion that can be bent along the second direction, A specific protrusion protruding from the other protrusions among the plurality of protrusions of the buffer body is inserted into a portion formed by opening the tongue piece, and the tip of the tongue piece is opposed to the inner wall. The portion fixed to the side plate portion and formed with the opening is the inner piece Opening in the second direction at one end, and in a state where the specific protrusion extends perpendicularly to a plane including the first direction and the second direction, The specific protrusion is inserted into the portion where the opening is formed by inserting the specific protrusion from a portion opened in the second direction.

The invention according to claim 2 is the packaging box according to claim 1, wherein the inner wall portion is a right or left end of upper, lower, left and right end portions of the article in a state of being accommodated in the packing body. It is characterized by being provided corresponding to the part.

According to the first aspect of the present invention, the inner piece that is continuous with the side plate portion that constitutes the outer surface of the package body is bent inside the package body, and is arranged with the side plate portion and the space separated from each other. The inner wall part which touches is formed. In other words, since a space partitioned by the inner wall portion is provided between the shock absorber and the side plate portion, even if an external impact or load is applied to the side plate portion, its corners, or ridge lines, it depends on the space. It is possible to prevent the buffer body from being deformed immediately, and as a result, it is possible to prevent the housed article from being damaged.
And since the buffer body is made of a pulp mold, and a plurality of protrusions are formed for buffering, the outer side is tapered for the convenience of drafting when the buffer body is molded, etc. The strength tends to be weak. However, since the shock absorber is in contact with the inner wall portion inside the packing body and is separated from the side plate portion, even if the shock absorber has a portion with insufficient strength, it can be reinforced to prevent deformation. it can.
In addition, since the protruding portion of the buffer body is inserted into the opening formed by the cutout portion or the bent tongue piece portion on the inner wall portion, rattling of the buffer body can be prevented.
Furthermore, since the tip of the tongue piece is fixed and supported on the side plate that faces the inner wall, the strength of the inner wall is improved.

According to the first aspect of the present invention, since the inner pieces that are bent inside the package are connected to the four side plate portions that constitute the package, the package is assembled from one sheet material. At the same time, the inner piece can be bent at the same time to form the inner wall, and the manufacturing process can be simplified. Moreover, since the front-end | tip of an internal piece is fixed and supported inside the package, the intensity | strength of the inner wall part formed of the internal piece is also improved.

  Furthermore, when storing the package with the article taken out, the inner piece constituting the inner wall is integrated with the package, so it can be stored together even if the package is deformed flat, It is easy to carry and the inner wall can be immediately formed in the original state when the package is restored next time.

According to the invention described in claim 2 , the inner wall portion is provided corresponding to the right or left end portion of the upper, lower, left and right end portions of the article in the state of being accommodated in the package. The buffer provided so as to cover the right or left end of the component is reinforced by providing the inner wall.

  Below, basic embodiment of the packaging box of this invention is described using drawing. The packaging box 100 of the present embodiment includes a box-shaped packaging body 1 that accommodates an article 3 to be packaged, and a buffer body 2 that covers at least a part of the article 3 and is accommodated in the packaging body 1. . Two shock absorbers 2 are provided so as to cover opposite ends of the article 3. The article 3 is covered with the buffer body 2 after being covered with the bag-like protective sheet 4.

In this embodiment, the article 3 is an image recording apparatus (see FIG. 5 , a printer apparatus, a facsimile apparatus, a multi-function decoding apparatus, etc.) that is one of electronic devices, It has a substantially rectangular parallelepiped shape whose height is shorter than the size and depth. That is, among the side surfaces of the article 3, the upper surface 3a and the lower surface 3b are side surfaces having the largest area. Strictly speaking, the upper surface 3a is not a flat surface because a lid and a display operation unit are provided.

  A cardboard box is applied to the packing body 1 and is formed in a rectangular parallelepiped shape corresponding to the article 3, and the top surface 1 a is an open surface. Further, in this specification, the “up and down”, “left and right”, and “front and back” directions of the image recording apparatus indicate that the image recording apparatus is in use (a state in which the lower surface 3b is placed facing a flat portion). Is the direction defined when the image recording apparatus is viewed from the front surface 3c. Furthermore, the up-down direction of the package 1 shall show the up-down direction of the package 1 shown in FIG.

  When the article 3 is accommodated in the package 1, the upper surface 3a and the lower surface 3b are substantially parallel to the vertical direction, that is, the upper surface 3a and the lower surface 3b are vertically oriented, and of the front and rear side surfaces in the use state, The front surface 3 c is positioned on the top surface 1 a side of the package 1. The article 3 which is an image recording device is provided with a paper cassette 3e inserted and removed from the front surface 3c thereof, and accessories such as instructions are accommodated in the paper cassette 3e at the time of packing. Therefore, by storing the front surface 3c of the article 3 toward the top surface 1a side of the packaging body 1, when the top surface 1a of the packaging body 1 is opened and the article 3 is taken out, the paper cassette 3e and the accessories included therein The product can be prevented from falling off.

  In the article 3 according to the present embodiment, the periphery of the left and right ends (ends on the short side of the upper surface 3a and the lower surface 3b) of the upper, lower, left, and right ends in the state of being accommodated in the package 1 is buffered. Covered by the bodies 2 and 2 respectively. That is, the two buffer bodies 2 are arranged so as to extend along the up-down direction of the packing body 1, and the recessed portions 5 for fitting the articles 3 are respectively long and recessed. In this embodiment, the buffer body 2 covers only both end portions of the article 3 and the central portion of the article 3 is exposed. However, the buffer body 2 may completely cover the periphery of the article 3.

  The buffer body 2 is made of a pulp mold formed by recycling waste paper, and has a large number of protrusions 80 on the inner and outer surfaces from the viewpoint of weight reduction and strength (shell structures such as corrugated parts, standing wall parts, box-like parts, and rib structures) )have. In other words, the shock absorber 2 prevents the positional deviation of the article 3 while providing a predetermined gap between the article 3 and the package 1 by forming a large number of protrusions 80 on the inner surface and the outer surface as described above. In addition, buffering against external loads and impacts is ensured. Further, the article 3 is positioned and fixed by contacting the article 3 with the top surface protruding to the inner side of each protrusion 80 of the shock absorber 2 (the inner surface of the recess 5). In addition, the protrusion 80 protruding from the outer surface of the buffer body 2 is formed in a tapered shape that narrows from the side where the recess 5 is provided to the opposite side in order to provide a draft angle during molding. .

  The packaging body 1 is formed by bending a corrugated cardboard sheet material 10 into a box shape. As shown in the developed view of FIG. 2, the sheet material 10 includes four side plate portions constituting the outer surface of the packaging body 1. 11a, 11b, 12a, 12b and an internal piece 13 are provided. As for the four side plate portions, the first side plate portions 11a and 11b and the second side plate portions 12a and 12b are alternately arranged. That is, the first side plate portion 11a, the second side plate portion 12b, the first side plate portion 11b, the second side plate portion 12b, and the internal piece 13 are connected in the order along the first direction (the X direction in FIG. 2). ing. In addition, the ruled line to which the bendability was provided was provided along each part and each piece folded by the package 1, and the folding line engraved so that the thickness of the raw material of the packing member 1 may be about half here 20 is provided.

  Of the four side plate portions, the first side plate portions 11a and 11b are opposed to the upper surface 3a and the lower surface 3b of the article 3, and thus are formed in a larger plane area than the second side plate portions 12a and 12b. Since the vertical dimensions of the side plates are the same, the width of the first side plates 11a and 11b is longer than the width of the second side plates 12a and 12b. The packing body 1 is formed into a quadrangular cylindrical shape by bending four side plate portions. At this time, the first side plate portion 11a located at the end portion on the side where the internal pieces 13 are not connected is the internal piece 13. Is fixed to the base end (partition wall 13b). It should be noted that an adhesive margin portion may be connected to the first side plate portion 11a, and this adhesive margin portion may be fixed to the second side plate portion 12b.

  An outer flap 15 is connected to both ends of the first side plate portions 11a and 11b on the second direction (Y direction in FIG. 2) side orthogonal to the first direction, and the second side plate portions 12a and 12b are connected to the second side. The inner flaps 16 are connected to both ends on the direction side. Each of the flaps 15 and 16 has a substantially rectangular shape, and is formed to have the same width as the side plate portion to which the flaps are connected. When covering the rectangular tube-shaped opening of the package 1, the pair of inner flaps 16 are folded, and then the pair of outer flaps 15 are folded, so that the inner flaps 16 are covered with the outer flaps 15. Thus, the flaps overlap at the upper and lower openings of the packing body 1 to form the top surface 1a and the bottom surface 1b of the packing body 1.

  The inner piece 13 is bent (folded) inside the rectangular tube shape of the packing body 1, and as shown in FIGS. 1, 3, and 4, a partition wall portion 13 b serving as a base end thereof is a first side plate portion. A portion that overlaps 11a and is bent in parallel with the second side plate portion 12b from the partition wall portion 13b constitutes an inner wall portion 17 that is disposed with a space from the second side plate portion 12b and that contacts the buffer body 2. . The distal end portion 13a of the internal piece 13 serves as an adhesive margin and is fixed to the first side plate portion 11b located at a position away from the partition wall portion 13b (base end) of the internal piece 13. The inner wall portion 17 is provided with a tongue piece portion 18 that is cut and formed in an L-shape when viewed from the side. The tongue piece portion 18 is bent toward the second side plate portion 12b, and a tip end portion 18a of the tongue piece portion 18 is formed. Is glued to the second side plate portion 12b and the tongue piece portion 18 is arranged orthogonal to the second side plate portion 12b. An opening 19 is formed in the inner wall portion 17 by bending the tongue piece portion 18.

  The shock absorber 2 on the side in contact with the inner wall portion 17 is provided with a protrusion 80a having a higher protrusion height than the other protrusions 80 so that it can be inserted into the opening 19 in advance. That is, of the protrusions 80 protruding toward the inner wall 17, the protrusion 80 a having a high protrusion height is inserted into the opening 19, and the top surfaces of the other protrusions 80 are in contact with the inner wall 17. The positions and sizes of the protrusion 80a and the tongue piece 18 are set in advance so that no rattling occurs when the protrusion 80a is inserted into the opening 19.

  According to the said structure, the inner wall part 17 spaced apart from the 2nd side plate part 12b is formed in the inner side of the package 1, and among the buffer bodies 2 arrange | positioned at the right and left of the articles | goods 3, one buffer body 2 is an inner wall part. 17 abuts. Since the inner wall portion 17 is fixed to the first side plate portion 11b by the tip portion 13a of the inner piece 13, and is fixed to the second side plate portion 12b by the tip portion 18a of the tongue piece portion 18, the first side plate portion 11b and this Is supported over both of the second side plate portions 12b intersecting with each other, and the strength of the inner wall portion 17 is increased. That is, in addition to the formation of a space with a predetermined interval between the inner wall portion 17 and the second buffer body 2, the strength of the inner wall portion 17 is increased, so that the space is not easily crushed.

  Since the space between the inner wall portion 17 and the second buffer body 2 is formed corresponding to the corner portion (ridge line portion) 1c of the packing body 1 on the second side plate portion 12b side (so as to cover), Insufficient strength of the buffer body 2 at the portion corresponding to the corner (ridge line portion) 1c of the package 1 is compensated. Therefore, it is possible to prevent the shock absorber 2 from being deformed together with the packing body 1 and causing the article 3 to be damaged when the corner (ridge line portion) 1c of the packing body 1 receives an impact or a load from the outside.

  Further, an inner wall portion parallel to the second side plate portion 12b and a tongue piece portion 18 orthogonal to the second side plate portion 12b are provided in the vicinity of the second side plate portion 12b. In other words, in the vertical direction. Since a plurality of extending surfaces (vertical surfaces) are provided, the strength of the packaging body 1 in the vertical direction can be improved, and the packaging box 100 can be stacked in the vertical direction with confidence.

  Further, since the inner piece 13 for forming the inner wall portion 17 is connected to the second side plate portion 12b and integrated with the packaging body 1, when the packaging body 1 is stored with the article 3 taken out, The packing body 1 can be folded flat with the internal piece 13 included, and can be carried together. And if necessary, when the packing body 1 is folded into the original rectangular tube shape and the article 3 is accommodated, the inner piece 13 can be easily restored to the shape of forming the inner wall portion 17. Therefore, as compared with the case where the inner wall portion 17 is configured separately from the package body 1 (another member is assembled to the package body 1), the storage space is not taken, and loss can be prevented.

  Moreover, since the protrusion 80a of the buffer body 2 is inserted exactly into the opening portion 19 formed by bending the tongue piece portion 18, there is an advantage that the displacement of the buffer body 2 can be suppressed.

  Furthermore, since the buffer body 2 on the side in contact with the inner wall portion 17 is reinforced by the inner wall portion 17, the depth dimension (recessed portion) of the buffer body 2 compared to the buffer body 2 on the side not in contact with the inner wall portion 17. 5) can be shortened, the moldability of the pulp mold can be improved, and the yield and molding accuracy can be increased. In addition, by shortening the depth dimension of the buffer body 2, even if a space is provided between the inner wall portion 17 and the second side plate portion 12 b, it is possible to suppress the entire packaging box 100 from being significantly enlarged. .

  In this embodiment, the tongue piece portion 18 is configured to be bent along a fold line 20 parallel to the second direction (Y direction), but is parallel to the inner wall portion 17 from the upper end to the lower end side. The tongue piece formed by providing the two cuts may be bent along a fold line parallel to the first direction (X direction). Further, although the strength of the inner wall portion 17 is somewhat inferior, the opening portion 19 for inserting the protrusion 80a may be formed by providing a cutout portion in the inner wall portion 17 instead of the tongue piece portion 18.

Note that the overall shape of the article 3 according to the above-described embodiment in use is a substantially rectangular parallelepiped shape whose height dimension is shorter than the width dimension and the depth dimension, and the front surface 3c of the article 3 is on the top surface 1a side of the packaging body 1. However, the shape of the article 3 and the orientation at the time of accommodation are not limited thereto. The article 3 may have any shape as long as it is a three-dimensional object having a width dimension, a depth dimension, and a height dimension, and is not limited to the illustrated image recording apparatus.

In the above-described embodiment, the inner wall portion 17 is provided with respect to the second side plate portion 12 having a small plane area. However, the inner wall portion 17 is provided corresponding to the arrangement position of the shock absorber 2 attached to the article 3. Therefore, the present invention is not limited to the above configuration.
