Description

  The present invention relates to an individual packaging box made of cardboard that holds a packaged product main body on a holding pad and accommodates it in the upper space and accommodates its accessories in the lower space, and in particular, can support the holding pad without providing a partitioning pad. It relates to an individual packaging box improved as described above.

  Conventionally, an individual packaging box made of cardboard for storing packages such as PNDs (portable navigation devices) has been designed to prevent the PND main body and accessories from coming into contact with each other due to vibration during transportation. The PND accessory is stored in the lower space of the box, and a partition pad is installed so as to cover the accessory, and the PND main body is held by the holding pad placed on the partition pad so that the upper space of the individual box Is housed in.

  On the other hand, in the corner part which touches the bottom part of each side of the packing box which stores an item to be packed, a notched line which forms a folding piece that can be folded back inside the packing box is provided, and the folded piece folded back inside the packing box In addition, a packaging device is known in which a lower front and rear cushioning body that protects the lower and front parts of the article to be packed is placed to form a space for storing the accessories of the article to be packed below the packaging box (patent Reference 1).

In addition, a tray container-like cardboard cushion with an opening at the top, a peripheral wall formed in the shape of a rectangular tube is arranged around the bottom surface, and cut off provided on the bottom plate at the four corners inside the peripheral wall.

  However, when the partition pad is provided inside like the above-described conventional individual packaging box, there is a problem that the number of parts and the number of assembling steps increase correspondingly and the cost is increased. Also, when storing accessories in the lower space of the individual packaging box, it is difficult to store the accessories because it must be stored so as not to interfere with the partition pad installed later. there were.

  On the other hand, like the packaging device of the above-mentioned Patent Document 1, the corners contacting the bottoms of the respective side surfaces of the packaging box are provided with folding pieces that are folded back into the inside of the packaging box. If the lower front and rear shock absorbers are placed on the piece and the storage space for the accessory is formed therebelow, an item corresponding to the above partition pad becomes unnecessary. However, if a box-shaped bent piece folded inward is provided at the corner of the packing box, the appearance of the packing box is impaired and the strength of the corner is also reduced. There was a problem that the packing cost became higher on the contrary. In addition, it is not easy to fold the corners of the packing box inward in a bowl shape, and it is difficult to make creases.

  Further, like the corrugated board shock absorber of Patent Document 2, when the cut pieces are formed at the four corners of the bottom plate, and the triangular prism-shaped member is provided at the four corners inside the peripheral wall, Since there are holes in the corners of the face plate where the cut pieces are formed and the appearance is impaired, even if this cardboard shock absorber technology is applied to an individual packaging box, it must be double packed in the same way as above. There was a problem that the packing cost became high.

  The present invention has been made under the circumstances described above, and the problem to be solved is that a partition pad is not required, and the holding pad of the packaged product main body can be supported and accommodated in the upper space without impairing the appearance or the like. It is to provide individual packaging boxes.

  In order to solve the above-mentioned problem, the individual packaging box according to the present invention bends the front and rear side plates connected to the bottom plate upward, and the left and right bent pieces connected to the front and rear side plates are bent inward to form the bottom plate. Bend the left and right outer faceplates upward and fold down the left and right inner faceplates that continue to the left and right outer faceplates, and sandwich the left and right bent pieces between the left and right outer faceplates and the left and right inner faceplates. In the individual packaging box made of corrugated board in which a holding body for holding the holding pad of the packaged product is accommodated, the left and right inner side plates are partially folded inside the box to form a folding support piece for supporting the holding pad. It is characterized by this.

  In the individual packaging box of the present invention, it is preferable that the lower ends of the left and right inner side plates are folded inside the box to form a folding support piece, and the folding angle of the folding support piece is set to 30 to 60 °. Is preferred. And it is preferable to extend the front-end | tip of this folding support piece, and to contact | abut to the side plates before and behind a box. It is also preferable to form a bowl-shaped kerf along the boundary line between the left and right inner side plates and the folding support pieces at the lower ends of both ends. Furthermore, it is also preferable that a protrusion is formed at the lower ends of the left and right inner side plates, a slit is formed inside the fold line between the bottom plate and the left and right outer side plates, and the protrusion is fitted into the slit.

  As in the individual packaging box of the present invention, when the left and right inner side plates are partially folded inside the box to form a folding support piece that supports the holding pad, the packaged accessories are accommodated in the lower space of the box. The holding pad holding the packaged product main body can be folded and directly supported by the support piece without being provided with a conventional partition pad, and can be accommodated in the upper space of the box. Therefore, the number of parts and the number of assembly steps are reduced by the amount that the partition pad is not required, and the cost can be reduced. In addition, by forming the folding support pieces on the left and right inner side plates, there are no holes in the front and rear side plates, left and right outer side plates, bottom plate, etc. of the box, so the appearance is impaired and the strength is reduced. Double packaging is also unnecessary. Further, when the partition pad is not required, it is not necessary to store the accessory so as not to obstruct the partition pad, so that it is easy to store the accessory. Since the holding pad also functions as a conventional partitioning pad, the packaged body and the accessory are vertically divided, so that there is no fear that the packaged body and the accessory come into contact with each other due to vibration during transportation.

  In the individual packaging box of the present invention, the folding support pieces are formed by folding the lower ends of the left and right inner side plates into the inside of the box body, because these folding support pieces are located inside the four corners of the box body. There is no risk of hindering the storage of the product, and the four corner portions of the holding pad can be stably supported by these folding support pieces. In particular, when the folding support piece has a folding angle of 30 to 60 °, the tip of the folding support piece is extended and brought into contact with the front and rear side plates of the individual packaging box, the folding support piece has an angle of 30 to 60 °. In this case, the four corners of the holding pad can be supported stably and reliably. The optimum folding angle of the folding support piece is 45 ° as in the embodiment described later.

  In addition, the shape in which the bowl-shaped kerf is formed along the boundary line between the left and right inner side plates and the folding support pieces at the lower ends of both ends has an advantage that the folding support piece can be easily folded. If the protrusion formed on the lower end of the inner side plate is fitted in the slit formed inside the fold line between the bottom plate and the left and right outer side plates, the inner side plate opens inside the box and the box expands There is an advantage that can be prevented.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an exploded perspective view of an individual packaging box and a holding pad accommodated therein according to an embodiment of the present invention, FIG. 2 is an exploded view of the individual packaging box, and FIGS. 7 is a perspective view illustrating the assembly procedure (folding procedure), FIG. 7 is a plan view of the same packaging box before closing the top surface portion, FIG. 8 is an enlarged sectional view taken along line AA in FIG. 6, and FIG. FIG.

  This individual packaging box 1 is manufactured by folding up a corrugated cardboard 10 in a development view as shown in FIG. 2, and as shown in FIG. 1 and FIG. It is held by the holding pad 2 and accommodated in the upper space of the individual packaging box 1, and accessories (not shown) such as a PND antenna, an AC power supply battery, a charging connector, and a vehicle stand are individually mounted. It is accommodated in the lower space of the box 1.

  The procedure for folding the individual packaging box 1 from the cardboard 10 shown in FIG. 2 will be described. First, as shown in FIG. 3, the front and rear side plates 1b and 1c connected to the rectangular bottom plate 1a are bent 90 ° upward. The left and right bent pieces 1d, 1d, 1e, 1e connected to the side plates 1b, 1c are bent inward by 90 °, respectively. Then, the left and right outer side plates 1f and 1g connected to the bottom plate 1a are bent upward by 90 °, and the left and right inner side plates 1h and 1i connected to the outer side plates 1f and 1g are folded downward by 180 ° and left and right outer side plates 1f. , 1g and the left and right inner side plates 1h, 1i sandwich the bent pieces 1d, 1d, 1e, 1e so that the holding pad 2 of the packaged product body W is accommodated in the upper part, as shown in FIGS. The box body 11 with the top plate 1p as shown in FIG.

  Projections 1j and 1k are formed at the lower ends (tips in the unfolded state) of the left and right inner side plates 1h and 1i turned downward 180 °, as shown in FIGS. Slits 1m and 1n are formed inside folding lines L1 and L1 between the bottom plate 1a and the left and right outer side plates 1h and 1i. The protrusions 1j and 1k at the lower ends of the left and right inner side plates 1h and 1i are fitted into the slits 1m and 1n, and the inner side plates 1h and 1i are fixed so as not to open inside the box.

  The left and right inner side plates 1h and 1i folded 180 ° downward are partially folded inside the box to form a folding support piece 1t that supports the holding pad 2. In the individual packaging box 1 of this embodiment, as shown in FIGS. 2 and 3, a total of four folding support pieces 1t are formed at the lower ends of the left and right inner side plates 1h, 1i (outer ends of both ends in the unfolded state). 1, 4, and 7, the respective folding support pieces 1 t are folded inside the four corners of the box 11 to support the four corner portions of the holding pad 2 from below as shown in FIG. 8. It is like that. Thus, when each folding support piece 1t is folded inside the four corners of the box 11, the folding support piece 1t becomes an obstacle when the accessory is accommodated in the lower space of the box 11. There will be no worries that will prevent their containment.

  Each folding support piece 1t has an optimum folding angle of 45 ° in the individual box 1 of this embodiment, and the front and back side plates 1b of the box body 11 are extended by extending the tip of each folding support piece 1t, It is in contact with 1c.

Since it does not return, the four corners of the holding pad 2 are reliably supported without being detached from the folding support piece 1r.

  The folding angle of each folding support piece 1t is optimally 45 ° as described above, but it is sufficient if it is within the range of 30 to 60 °. When the folding angle is smaller than 30 ° or larger than 60 °, the four corner portions of the holding pad 2 are easily detached from the upper end of the folding support piece 1t, and there is a concern that the holding pad 2 falls. When the folding angle is 30 to 60 °, the holding pad 2 can be reliably supported without such a concern.

  The folding length of each folding support piece 1t is not particularly limited. However, if the folding support piece 1t is too long, the folding support piece 1t may protrude greatly toward the inside of the box 11 and hinder the accommodation of the accessory. If it is too large, the four corners of the holding pad 2 will be easily detached from the folding support piece, and therefore it is preferably about 20 to 70 mm.

  Further, as shown in FIGS. 2 and 3, it is preferable to form a bowl-shaped cut groove 1u along a boundary line L2 between the left and right inner side plates 1h, 1i and the folding support pieces 1t at the lower portions of both sides thereof, When such a kerf 1u is formed, there is an advantage that the folding support piece 1t can be easily folded.

  As described above, the individual packaging box 1 folds the folding support pieces 1t at the lower ends of the left and right inner side plates 1h and 1i into the insides of the four corners of the box body 11, and accommodates accessories in the lower space of the box body 11. After that, the four corners of the holding pad 2 holding the package body W are folded and supported by the support pieces 1t and accommodated in the upper space of the box 11, and as shown in FIG. 5, the left and right flaps 1q, While inserting 1q between the left and right inner side plates 1h, 1g of the box 11 and the holding pad 2, the top plate 1p is bent 90 ° forward to cover the box 11, and as shown in FIG. The left and right small flaps 1s, 1s connected to the front plate 1r are inserted between the left and right outer side plates 1f, 1g and the bent pieces 1d, 1d while the front plate 1r connected to the top plate 1p is bent 90 ° downward.

Since it can be supported directly in the upper space of the box 11, the number of parts and the number of assembly steps can be reduced by the amount that the partition pad is unnecessary, and the accessory can be stored easily. It becomes. In addition, the folding support pieces 1t are formed on the left and right inner side plates 1h and 1i so that the front and rear side plates 1b and 1c, the left and right outer side plates 1f and 1g, the bottom plate 1a, and the like have no holes. As a result, the appearance is not impaired or the strength is not reduced, and double packaging is not required. In addition, since the holding pad 2 also functions as a conventional partitioning pad, the packaged body W and the accessory are divided up and down, so that there is no fear of the packaged body W and the accessory coming into contact with each other due to vibration during transportation. .

  The holding pad 2 for holding the packaged product main body W is manufactured by folding up the corrugated cardboard 20 in a development view as shown in FIG. 9 in the following procedure. That is, the side surface portions 2b and 2c connected to both sides of the top surface portion 2a are bent 90 ° downward, the bottom surface portion 2d connected to the side surface portion 2c is bent 90 ° below the top surface portion 2a, and the side surface portion 2e connected to the bottom surface portion 2d is bent. Folded 90 ° upward and overlaid on the side surface portion 2b, bent the projection 2f of the side surface portion 2b by 90 ° and inserted into the slit 2g of the side surface portion 2e, and four folded pieces 2h, 2i, 2j, 2k formed on the top surface portion 2a.
