Description

The present invention relates to a packaging box in which a roll-shaped medium such as roll paper is housed.

Conventionally, in a commercial printer or the like, a monotonous image such as a gradation image, characters, and symbols has been formed on a base material by using a thermal transfer method. As the thermal transfer method, a heat-sensitive sublimation transfer method and a heat-sensitive melt transfer method are widely used. Of these, the thermal sublimation transfer method uses a thermal transfer sheet in which a dye layer in which a sublimation dye used as a coloring material is melted or dispersed in a binder resin is supported on a base sheet, and this thermal transfer sheet is used as a dye receiving layer. By applying energy according to the image information to a heating device such as a thermal printer head, the sublimation dye contained in the dye layer on the thermal transfer sheet is transferred to the thermal transfer image receiving sheet. Is a method of forming.

In addition, roll paper is generally used as a heat transfer image receiving sheet in commercial printers and the like that use the above heat transfer method, but when carrying this roll paper, the roll paper should be transported in a cardboard box as it is. For this reason, the roll paper may move inside the cardboard box during transportation, and the outer peripheral surface and edge portions thereof may be scratched. For this reason, normally, the holding member is packed together with the roll paper in the cardboard box, and the roll paper is held by the holding member so as not to move in the cardboard box. For example, Patent Document 1 describes a technique in which bearing members are installed at both ends of a roll paper having a winding core, and the bearing portion of each bearing member is inserted into the winding core of the roll paper to support the roll paper. Is disclosed.

Further, Patent Documents 2 and 3 disclose a technique relating to a packaging structure of roll paper that can be reliably held even if the roll paper does not have a winding core.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 9 are views showing a packing box in which a roll-shaped medium such as roll paper is housed according to the present embodiment. Although the packaging boxes shown in FIGS. 1 to 9 accommodate two roll-shaped media, the number of roll-shaped media accommodated in the packaging box in the present embodiment is limited to two. There is no such thing. Further, in FIGS. 1 to 9, the roll-shaped medium contained in the packing box is indicated by reference numeral R, and the hollow portion having a circular cross section of the roll-shaped medium is indicated by reference numeral C.

The packing box 10 according to the present embodiment is composed of, for example, a cardboard box or the like, and has a side surface 12, a pair of inner flaps 14 on the bottom side, a pair of outer flaps 16 on the bottom side, and a pair of inner flaps on the ceiling side. It includes a flap 18 and a pair of outer flaps 20 on the ceiling side. More specifically, from the state shown in FIG. 1, the bottom portion of the packing box 10 is closed by folding the pair of outer flaps 16 on the bottom side in the direction of the arrow in FIG. Then, after the two roll-shaped media are housed in the packing box 10 having the bottom closed, the pair of inner flaps 18 on the ceiling side and the pair of outer flaps 20 on the ceiling side are respectively arranged in the arrow directions in FIG. By folding, the ceiling portion of the packing box 10 is closed. In this way, the packing box 10 containing the two roll-shaped media having the ceiling closed can be carried. Further, in the present embodiment, when the bottom portion and the ceiling portion of the packing box 10 are closed, the inner flaps 14 and the inner flaps 18 are folded when the inner flaps 14 and the inner flaps 18 are folded. They are in contact with each other. Further, when the bottom portion and the ceiling portion of the packing box 10 are closed, the outer flaps 16 and the outer flaps 20 come into contact with each other when the outer flaps 16 and the outer flaps 20 are folded. There is.

As shown in FIGS. 1 and 6, each inner flap 14 on the bottom side and each inner flap 18 on the ceiling side are formed with circular through holes 30. Further, a holding member 40 as shown in FIG. 4 is passed through the through hole 30, and the ceiling portion and the bottom portion of the roll-shaped medium housed in the packing box 10 are respectively formed by the holding member 40. It is designed to be retained. More specifically, the holding member 40 has a hollow disk-shaped base portion 44 and a hollow protruding portion 42 protruding from one surface of the base portion 44, and the holding member 40 is shown in FIG. When viewed from the upper side to the lower side, the protruding portion 42 and the base portion 44 each have a concentric circular shape. Further, such a holding member 40 is made of a material such as plastic. Here, the diameter of the protruding portion 42 when the holding member 40 is viewed downward from the upper side in FIG. 4 is slightly smaller than the diameter of the through hole 30, and the holding member 40 is seen from the upper side in FIG. The diameter of the base portion 44 when viewed downward is larger than the diameter of the through hole 30. Further, the diameter of the protruding portion 42 when the holding member 40 is viewed from the upper side to the lower side in FIG. 4 is slightly smaller than the diameter of the hollow portion of the roll-shaped medium. Therefore, when the holding member 40 is fitted into the through hole 30 formed in the inner flap 14 from the outside of each inner flap 14 on the bottom side, the base portion 44 is located below the inner flap 14 while protruding. By projecting the portion 42 upward toward the inside of the inner flap 14, the protruding portion 42 is inserted into the hollow portion in the bottom portion of the roll-shaped medium housed in the packing box 10. Further, when the holding member 40 is fitted into the through hole 30 formed in the inner flap 18 from the outside of each inner flap 18 on the ceiling side, the base portion 44 is located above the inner flap 18 while the protruding portion 42. By projecting downward toward the inside of the inner flap 18, the projecting portion 42 is inserted into the hollow portion in the ceiling portion of the roll-shaped medium housed in the packing box 10. In this way, by inserting the protruding portion 42 of the holding member 40 into the hollow portion in the bottom portion and the ceiling portion of the roll-shaped medium, the roll-shaped medium accommodated in the packing box 10 is positioned. In the present embodiment, the roll-shaped medium housed in the packing box 10 is positioned by the through holes 30 and the holding member 40 formed in the inner flaps 14 on the bottom side and the inner flaps 18 on the ceiling side, respectively. The part is configured.

Further, as shown in FIGS. 1, 2, 6 and the like, a square through hole 32 is formed on the outside of each through hole 30 in each of the inner flaps 14 on the bottom side. Here, in each inner flap 14, the through hole 32 is provided in the vicinity of the boundary between the inner flap 14 and the side surface 12 adjacent to the inner flap 14. Further, as shown in FIG. 2, in each inner flap 14, at least a part of the through hole 32 is a region facing the roll-shaped medium positioned by a positioning portion such as a holding member 40 in the inner flap 14 (in FIG. 2). It is located outside the reference code R). Specifically, the virtual line connecting the opposite corners in the square through hole 32 (indicated by reference numeral B in FIG. 2) is substantially parallel to the boundary between the inner flap 14 and the side surface 12 adjacent to the inner flap 14. This virtual line is located outside the region facing the roll-shaped medium positioned by the positioning portion such as the holding member 40 in the inner flap 14.

When such a through hole 32 is formed in each inner flap 14, when an operator accidentally drops the packing box 10 during transportation of the packing box 10 containing the roll-shaped medium, each of the through holes 32 is formed. Since the through hole 32 in the inner flap 14 is weaker than the other parts, the part around the through hole 32 in the inner flap 14 is destroyed by the impact when the dropped packing box 10 collides with the ground. It will be like. Specifically, due to the impact when the dropped packing box 10 collides with the ground, the inner flap 14 becomes a virtual line connecting the opposite corners of the square through hole 32 (indicated by reference numeral B in FIG. 2). You will be able to break along. Here, since the virtual line connecting the facing corners of the square through hole 32 is located outside the region facing the roll-shaped medium positioned by the positioning portion such as the holding member 40 in the inner flap 14. Even if the inner flap 14 is broken due to the impact when the packing box 10 is dropped, the roll-shaped medium is not damaged. In particular, when the through hole 32 is provided in the vicinity of the boundary between the inner flap 14 and the side surface 12 adjacent to the inner flap 14, the impact of the packing box 10 when dropped causes the through hole 32 to reach the side surface 12 of the inner flap 14. The vicinity of the boundary is easily destroyed, and in this case, the roll-shaped medium located at the center of the inner flap 14 is further suppressed from being damaged. As described above, the through hole 32 formed in each inner flap 14 faces the roll-shaped medium positioned by the positioning portion such as the holding member 40 in the inner flap 14 when the packing box 10 is impacted from the outside. It comes to function as a destruction guiding means for destroying the packing box 10 at a location outside the region.

Here, in the present embodiment, the vertical and horizontal lengths of the inner flaps 14 shown in FIG. 2 are, for example, 21 cm and 15 cm, respectively, and the diameter of the through hole 30 into which the holding member 40 is fitted is large. The diameter is, for example, 6 cm. Further, the diameter of the roll-shaped medium housed in the packing box 10 is, for example, 13 cm. Further, the square through hole 32 is a square having a size of 2 cm on each side, and the through hole 32 is inclined by about 45 ° with respect to each side of the inner flap 14. Further, the distance between the center of the through hole 30 and the center of the through hole 32 is slightly larger than the size of the radius of the roll-shaped medium housed in the packing box 10 of 6.5 cm.

It should be noted that the destruction guiding means for destroying the packing box 10 at a position outside the region facing the roll-shaped medium positioned by the positioning portion in the inner flap 14 when the packing box 10 is impacted from the outside is inside each. It is not limited to the through hole 32 formed in the flap 14. As the fracture guiding means, a notch or a notch formed in each inner flap 14 may be used. Even when a notch or a cut is formed in each inner flap 14, the portion where the notch or the cut is formed in each inner flap 14 is a weaker portion than the other portion. Therefore, when the operator accidentally drops the packing box 10 during the transportation of the packing box 10 containing the roll-shaped medium, the inner flap is caused by the impact when the dropped packing box 10 collides with the ground. The portion of the 14 where the notch or cut is formed will be destroyed. Also in this case, if the portion of the inner flap 14 where the notch or cut is formed is located outside the region facing the roll-shaped medium positioned by the positioning portion of the inner flap 14. The roll-shaped medium is not damaged even if the notch or the notch formed in the inner flap 14 is destroyed by the impact when the packing box 10 is dropped.

If no breaking guiding means such as a through hole 32, a notch, or a cut is formed in each inner flap 14, an operator may perform the transportation of the packing box 10 containing the roll-shaped medium. When the packing box 10 is accidentally dropped, it is unknown which part of the inner flap 14 is destroyed by the impact when the dropped packing box 10 collides with the ground. In this case, the portion of the inner flap 14 in the vicinity of the through hole 30 may be destroyed, and at this time, the roll-shaped medium contained in the packing box 10 may be damaged.

Further, in the present embodiment, when the roll-shaped medium is housed in the packing box 10, the holding member 40 is fitted into the through hole 30 formed in the inner flap 14 from the outside of each inner flap 14 on the bottom side. After the protruding portion 42 of the holding member 40 is projected upward toward the inside of the inner flap 14, the shock absorbing material 50 as shown in FIG. 7 is packed before the roll-shaped medium is housed in the packing box 10. It is designed to be placed on the inner bottom surface of the box 10. As a result, when the roll-shaped medium is housed in the packing box 10, the impact absorbing material 50 is sandwiched between the inner bottom surface of the packing box 10 and the bottom surface of the roll-shaped medium positioned by the holding member 40. , The impact when the packing box 10 falls and collides with the ground can be softened by the impact absorbing material 50.

As shown in FIG. 7, the shock absorbing material 50 connects two donut-shaped portions 52 having a diameter slightly larger than the diameter of the roll-shaped medium housed in the packing box 10 and connecting these donut-shaped portions 52. It has a portion 54 and. Here, a through hole 52a is formed in the center of each donut-shaped portion 52, and the diameter of the through hole 52a is slightly larger than the diameter of the protruding portion 42 of the holding member 40. As a result, when the shock absorbing material 50 as shown in FIG. 7 is placed on the inner bottom surface of the packing box 10, the through hole 52a of each donut-shaped portion 52 in the shock absorbing material 50 protrudes from each holding member 40. When the portion 42 penetrates, the protruding portion 42 protrudes upward from the impact absorbing material 50. Further, as shown in FIG. 7, the length of the connecting portion 54 in the vertical direction of FIG. 7 is large enough to reduce the impact absorbing material 50 to such an extent that the strength of the impact absorbing material 50 does not extremely decrease. It is preferable that it is. Further, when the number of roll-shaped media accommodated in the packing box 10 is one, it is not necessary to provide the connecting portion 54 in the impact absorbing material 50, and the impact absorbing material 50 is composed of only the donut-shaped portion 52. It will be.

Further, the impact absorbing material 50 as shown in FIG. 7 is placed on the inner bottom surface of the packing box 10, and the protruding portion 42 of each holding member 40 penetrates the through hole 52a of each donut-shaped portion 52 in the impact absorbing material 50. When this is done, the shock absorbing material 50 does not come into contact with the inner side surface of the packing box 10. In this case, since the impact when the packing box 10 falls and collides with the ground is not directly transmitted from the inner side surface of the packing box 10 to the impact absorbing material 50, the roll placed on the impact absorbing material 50 is placed. It becomes possible to further suppress the damage of the state medium. Further, the outer edge of each donut-shaped portion 52 of the impact mitigating material 50 and a virtual line connecting the opposite corners in the through hole 32 (indicated by reference numeral B in FIG. 2) are substantially in contact with each other. In this case, it is possible to prevent the shock absorbing material 50 from being damaged by the impact when the operator accidentally drops the packing box 10 during the transportation of the packing box 10 containing the roll-shaped medium. You will be able to. Further, since the connecting portion 54 connecting the two donut-shaped portions 52 straddles the boundary when the pair of inner flaps 14 on the bottom side is folded, the boundary between the pair of folded inner flaps 14 is reached. The strength of the nearby portion can be increased by the connecting portion 54.

As shown in FIG. 8, the impact absorbing material sandwiched between the inner bottom surface of the packing box 10 and the bottom surface of the roll-shaped medium positioned by the holding member 40 when the roll-shaped medium is housed in the packing box 10. Impact absorbing material 60 may be used. The shock absorbing material 60 shown in FIG. 8 is formed with two through holes 60a having a diameter slightly larger than the diameter of the protruding portion 42 of the holding member 40. As a result, when the shock absorbing material 60 as shown in FIG. 8 is placed on the inner bottom surface of the packing box 10, the protruding portion 42 of each holding member 40 penetrates each through hole 60a in the shock absorbing material 60. As a result, the protruding portion 42 protrudes upward from the impact absorbing material 60. Further, in the impact absorbing material 60 shown in FIG. 8, a pair of notches 62 are formed on the outside of the roll-shaped medium held by the protruding portion 42 of each holding member 40. Such a notch 62 has a shape generally along the edge of the roll-shaped medium held by the protruding portion 42 of each holding member 40.

When the impact absorbing material 60 as shown in FIG. 8 is placed on the inner bottom surface of the packing box 10 and the protruding portion 42 of each holding member 40 penetrates each through hole 60a in the impact absorbing material 60, the impact absorbing material is used. The edge of 60 is in contact with the inner side surface of the packing box 10. In this case, the impact when the packing box 10 falls and collides with the ground is directly transmitted from the inner side surface of the packing box 10 to the shock absorbing material 60, so that the shock absorbing material 60 is destroyed. The roll-shaped medium placed on the impact absorbing material 60 may be damaged. As described above, the impact absorbing material 50 shown in FIG. 7 has better performance than the impact absorbing material 60 shown in FIG.

Next, the roll-shaped medium housed in the packing box 10 according to the present embodiment will be described. The roll-shaped medium is a roll paper made of a thermal transfer image receiving sheet used in a thermal transfer type commercial printer or the like, and the thermal transfer image receiving sheet has a multilayer structure in which a receiving layer is laminated on one side or both sides of a base material. Here, the base material constituting the thermal transfer image receiving sheet has a role of holding the receiving layer, and since heat is applied during thermal transfer, it is a material having mechanical strength to the extent that it does not hinder handling even in an overheated state. Is preferable. The base material is not particularly limited, and is, for example, condenser paper, glassin paper, sulfate paper, high-sized paper, synthetic paper (polyolefin-based, polystyrene-based), high-quality paper, art paper, and the like. Coated paper, cast coated paper, wallpaper, backing paper, synthetic resin or emulsion impregnated paper, synthetic rubber latex impregnated paper, synthetic resin inner sheet paper, paperboard, etc., cellulose fiber paper, or polyester, polyacrylate, polycarbonate, polyurethane, polyimide, Polyetherimide, cellulose derivatives, polyethylene, ethylene-vinyl acetate copolymer, polypropylene, polystyrene, acrylic, polyvinyl chloride, vinylidene chloride, polyvinyl alcohol, polyvinyl butyral, nylon, polyether ether ketone, polysulfone, polyether sulfone , Tetrafluoroethylene, perfluoroalkyl vinyl ether, polyvinylfluoride, tetrafluoroethylene / ethylene, tetrafluoroethylene / hexafluoropropylene, polychlorotrifluoroethylene, polyvinylidenefluoride and the like, and synthesis thereof. A white opaque film formed by adding a white pigment or a filler to a resin can also be used, but is not limited thereto. Further, a laminated body made of any combination of the above-mentioned base materials can also be used. Examples of a typical laminate include a laminate of cellulose fiber paper and synthetic paper, or a laminate of cellulose synthetic paper and a plastic film. The thickness of the base material can be appropriately changed depending on the strength and heat resistance required for the thermal transfer image receiving sheet and the material of the material used as the base material. The thickness of the thermal transfer image receiving sheet is preferably in the range of 50 μm or more and 1000 μm or less, and more preferably in the range of 150 μm or more and 600 μm or less.

Further, the receiving layer formed on one side or both sides of the base material in the thermal transfer image receiving sheet receives the sublimation dye transferred from the thermal transfer ink sheet at the time of image formation by thermal transfer, and retains the received sublimation dye in the receiving layer. By doing so, an image is formed and maintained on the surface of the receiving layer. As the resin forming the receiving layer, a vinyl chloride resin such as polyvinyl chloride or a vinyl chloride-vinyl acetate copolymer (vinyl acetate resin) can be preferably used, but in addition, a cross-linking agent and a mold release agent can be used. Agents and other additives may be further included.

The roll-shaped medium housed in the packing box 10 according to the present embodiment is not limited to the roll paper made of a thermal transfer image receiving sheet used in a thermal transfer type commercial printer or the like. As the roll-shaped medium, a roll paper other than the thermal transfer image receiving sheet may be used, or a sheet other than the paper rolled into a cylindrical shape may be used.

According to the packing box 10 of the present embodiment having the above-described configuration, a positioning portion (specifically, a through hole 30 and a holding member 40) for positioning the rolled medium to be accommodated and packing from the outside. When the box 10 is impacted, the packing box 10 is destroyed at a position outside the region facing the roll-shaped medium positioned by the positioning portion in the packing box 10 (specifically, the inner flap 14). It is provided with a guiding means (specifically, a through hole 32). In this case, even if the packing box 10 is accidentally dropped during transportation, the packing box is located outside the region facing the roll-shaped medium positioned by the positioning portion in the packing box 10 by the destruction guiding means. Since the 10 is destroyed, it is possible to prevent the roll-shaped medium contained in the packing box 10 from being damaged.

Further, in the packing box 10 of the present embodiment, as described above, the destruction guiding means is a through hole 32, a notch or a cut formed in the inner flap 14 of the packing box 10. When the fracture guiding means is a through hole 32 formed in the inner flap 14 of the packing box 10, at least a part of the through hole 32 is formed in a roll-shaped medium positioned by a positioning portion in the inner flap 14. It will be located outside the opposite area. Further, the through hole 32 formed in the inner flap 14 of the packing box 10 has a square shape. In this case, the virtual line connecting the opposing corners of the through hole 32 (indicated by reference numeral B in FIG. 2) is located outside the region facing the roll-shaped medium positioned by the positioning portion in the inner flap 14. It is designed to do. Further, the virtual line connecting the opposite corners in the through hole 32 is substantially parallel to the boundary between the inner flap 14 in the packing box 10 and the side surface 12 adjacent to the inner flap 14. The through hole 32 is not limited to a quadrangular shape, and may be a circular shape, a triangular shape, or a polygonal shape of a pentagon or more. However, when the through hole 32 is a quadrangular shape, the packing box 10 It becomes easier to limit the place where the sword is destroyed to a specific place (specifically, a virtual line connecting the corners in a quadrangle), and thus the roll-shaped medium contained in the packing box 10 is further damaged. Can be suppressed. Further, instead of the square through hole 32 as shown in FIG. 3, the rugby ball-shaped (in other words, lemon-shaped) through hole 34 consisting of two arcs including two corners as shown in FIG. 9 is a packing box. It may be formed on the inner flap 14 of the ten. In this case, the virtual line connecting the two corners of the rugby ball shape in the through hole 34 (indicated by reference numeral B in FIG. 9) is larger than the region facing the roll-shaped medium positioned by the positioning portion in the inner flap 14. It is preferable that it is located on the outside. In this case, the place where the packing box 10 is destroyed is limited to the virtual line connecting the two opposite corners in the rugby ball-shaped through hole 34, so that the roll housed in the packing box 10 is contained. It is possible to further prevent the state medium from being damaged.

Further, in the packing box 10 of the present embodiment, as described above, the destruction guiding means is provided in the vicinity of the boundary between the inner flap 14 of the packing box 10 and the side surface 12 adjacent to the inner flap 14. .. In this case, the impact of dropping the packing box 10 tends to destroy the vicinity of the boundary between the inner flap 14 and the side surface 12, and in this case, the roll-shaped medium located at the center of the inner flap 14 is damaged. It is even more suppressed. Further, in the packing box 10 of the present embodiment, the pair of inner flaps 14 are in contact with each other. In this case, the impact when the packing box 10 falls and collides with the ground can be absorbed to some extent between the pair of inner flaps 14.

Further, in the packing box 10 of the present embodiment, as described above, an impact absorbing material is provided between the inner bottom surface of the packing box 10 and the bottom surface of the roll-shaped medium positioned by the positioning portion inside the packing box 10. The 50 is sandwiched so that the shock absorbing material 50 does not come into contact with the inner side surface of the packing box 10. In this case, since the impact when the packing box 10 falls and collides with the ground is not directly transmitted from the inner side surface of the packing box 10 to the impact absorbing material 50, the roll placed on the impact absorbing material 50 is placed. It becomes possible to further suppress the damage of the state medium. Further, the shock absorbing material 50 has a donut-shaped portion 52 having a diameter larger than the diameter of the roll-shaped medium to be accommodated in the packing box 10. The impact mitigating material sandwiched between the inner bottom surface of the packaging box 10 and the bottom surface of the roll-shaped medium positioned by the positioning portion inside the packaging box 10 has an impact shape as shown in FIGS. 7 and 8. It is not limited to the relaxation materials 50 and 60. Here, in impact absorbing materials having various shapes other than the impact absorbing materials 50 and 60 shown in FIGS. 7 and 8, when they are placed on the inner bottom surface of the packing box 10, they do not come into contact with the inner side surface of the packing box 10. It is preferable that a shape is used.

The packaging box according to the present invention is not limited to the above-described embodiment, and various modifications can be made.

For example, in the packaging box according to the present invention, when the packaging box is impacted from the outside, the packaging box is destroyed at a position outside the region facing the roll-shaped medium positioned by the positioning portion of the packaging box. The guiding means may be formed on the outer flap or the side surface instead of the inner flap.

Further, in the packing box according to the present invention, the positioning portion is not limited to the one composed of a through hole formed in the inner flap and a holding member passing through the through hole.
