Description

  The present invention relates to a packaging box in which impact is not easily transmitted to a product.

  Conventionally, there is a packaging box for storing a product via a cushioning material. That is, when the product is a precision instrument such as a scanner of an electronic copying machine, the product is stored in a packing box via a cushioning material so as to be less susceptible to a drop impact.

  Examples of the cushioning material include a cellular cushioning material (commonly known as an air cap sheet), and the product is wrapped in the cellular cushioning material and stored in a packaging box. In addition, there is a foamed polystyrene molded product, and the foamed polystyrene molded product is fitted on both sides of the product and stored in a packaging box.

  These cushioning materials are bulky when not in use, and there is a problem that processing after disposal (incineration and landfilling) affects the environment.

Therefore, in order not to be bulky when not in use and to prevent the incineration after disposal from affecting the environment, the product is bound to the inner plate as a cushioning material in a cross shape with a band material, and the inner plate is While raising the first height adjustment plate on the top and lowering the second height adjustment plate directly below, apply the first height adjustment plate and the second height adjustment plate to the inner surface of the four sides of the packaging box. However, a packaging box has been proposed in which an inner plate is fitted into a packaging box while being less susceptible to a drop impact (see Patent Document 1).
JP 2004-284658 A

  However, in the packaging box of Patent Document 1, since the height adjustment plate is only raised and lowered from directly above and below the inner plate, the height adjustment plate itself is poor in elasticity. When an impact such as a drop is applied to the box, there is a problem that the impact from the packaging box is easily transmitted to the product.

  The present invention has been made to solve the above-mentioned problems, and it is difficult for the impact from the packaging box to be transmitted to the product, it is not bulky when not in use, and the disposal such as incineration after disposal does not affect the environment. The purpose is to provide a box.

  In order to solve the above-mentioned problems, the present invention provides a packaging box for storing a product via a cushioning material, wherein a flexible packaging bag for storing the product is provided, while the cushioning material is elastic. A downwardly bent leg part and an upwardly bent leg part are formed on both sides in the length direction of the horizontal center part, and the packaging is provided on the downwardly bent leg part before the folding. By fixing both ends of the bag and bending the downward folding legs downward, the product stored in the packaging bag is positioned on the upper surface of the central portion while the packaging bag is pulled in the length direction. When the cushioning material is fitted in the packaging box, the lower end of the downward folding leg is positioned near the lower corner of the packaging box, and the upper end of the upward folding leg is placed in the packaging box. Near the upper corner There is provided a packing box, characterized in that so as to location.

  According to a second aspect of the present invention, the downward bending leg portion of the cushioning material is formed in the middle portion in the width direction of the central portion, and the upward bending leg portion is formed in both side portions in the width direction of the central portion. Is preferred.

  It is preferable that the packaging bag has a configuration in which only one side in the length direction is opened.

  According to a fourth aspect of the present invention, a hook hole is formed at both ends of the packaging bag, and a hook portion for locking and fixing the hook hole of the packaging bag is formed at the downwardly bent leg portion of the cushioning material. preferable.

  It is preferable to have a configuration in which a bending cut portion is formed in the central portion of the cushioning material.

  According to a sixth aspect of the present invention, it is preferable that a concavo-convex portion is formed at both end portions in the width direction of the central portion of the cushioning material.

  According to the present invention, when both ends of the packaging bag containing the product are fixed to the downward folding leg portions before folding the cushioning material and the downward folding leg portions are folded downward, the packaging bag is pulled in the length direction. In this state, the product stored in the packaging bag is positioned on the upper surface of the central portion of the cushioning material. In this state, the cushioning material is fitted into the packaging box so that the lower end of the downward folding leg is positioned near the lower corner of the packaging box, and the upper end of the upward folding leg is placed in the packaging box. When placed in the vicinity of the upper corner, the downward folding leg and the upward folding leg of the cushioning material are stretched at the upper and lower four corners in the packaging box, and the product stored in the packaging bag is cushioned. It will be held near the center of.

  At this time, since the cushioning material has elasticity, even if an impact such as a drop acts on the packaging box, the impact from the packaging box is caused by the elasticity of the downward folding leg and the upward folding leg and the elasticity of the center. Is difficult to communicate with the product. In addition, since the flexible packaging bag is pulled and fixed in the lengthwise direction by the downward folding leg, the impact from the downward folding leg, upward folding leg and central part is also applied to the product. It becomes difficult to be transmitted.

  Furthermore, the cushioning material can be constructed by folding a single sheet at the time of use, and since only a separate packaging bag is provided, the structure is simple and the cost is low, and it can be folded flat when not in use, so it is not bulky. At the same time, since the cushioning material can be made of a corrugated cardboard sheet or the like, processing such as incineration after discarding does not affect the environment. Furthermore, since the product is stored in the packaging bag, there is no possibility that dust or the like adheres.

  According to claim 2, the product can be positioned in the middle portion in the width direction of the central portion by forming the downward folding leg portion in the middle portion in the width direction of the central portion, and the upward bending leg portion is in the center. By forming on both sides in the width direction of the part, the cushioning material can be evenly stretched at the four corners in the packaging box, and the product can be held near the center part.

  According to claim 3, when both ends of the packaging bag containing the product are respectively fixed to the downward folding leg portion before folding, and the downward folding leg portion is bent downward, the packaging bag is pulled in the length direction. Thus, the packaging bag is strongly pressed against the bent edge of the downward bent leg portion. Therefore, the packaging bag containing the product from the opening on one side is naturally sealed with the opening side strongly pressed against the bent edge, so that it is not necessary to seal it in advance. Further, when the cushioning material is taken out from the packaging box and the packaging bag is removed from the downward bent leg portion, the sealing on the opening side is naturally released, so that the product can be smoothly taken out from the packaging bag.

  According to the fourth aspect of the present invention, since both ends of the packaging bag can be fixed to the downwardly bent leg portions simply by locking the hook holes at both ends of the packaging bag to the hook portions of the downwardly bent leg portions of the cushioning material, the fixing operation is easy. become.

  According to the fifth aspect, since the elasticity of the central portion of the cushioning material is increased by the bending cut portion, the impact from the central portion is hardly transmitted by the product.

  According to the sixth aspect, even if an impact in the width direction acts on the packing box, the bumps at the center of the cushioning material collide with the inner surface of the packing box and are crushed so that the shock is weakened. The impact in the width direction from is difficult to be transmitted to the product.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 4, a rectangular parallelepiped packing box 1 is, for example, a cardboard box, and an upper opening 1a is closed by a lid (flap) 1b.

  As shown in FIGS. 1 and 2 (a), a flexible packaging bag 3 is provided. The packaging bag 3 is, for example, a polyethylene bag (or a paper bag), and both side portions 3a in the width direction W are sealed. In addition to being formed in a sheath shape, an opening 3b is formed on one end side in the length direction L, and the other end side is sealed with, for example, a heat seal portion 3c. At both ends of the packaging bag 3, hook holes 3 d that are long in the width direction W are formed. The product 2 is stored in the packaging bag 3 through the opening 3b. The product 2 is, for example, a scanner of an electronic copying machine and is drawn in a rectangular parallelepiped shape.

  As shown in FIG. 1 and FIG. 2B, the cushioning material 4 used when the product 2 is stored in the packaging box 1 is a single rectangular sheet body having elasticity, for example, a cardboard sheet (plastic A sheet is also acceptable).

  The central portion 4a in the length direction L of the cushioning material 4 is formed in a substantially square shape, and is bent obliquely downward at a mountain fold line a on both sides of the central portion 4a in the length direction L (20 to 70 with respect to the horizontal plane). A slanting downward bending leg 4b and a slanting upward bending leg 4c that can be folded obliquely upward (about 20 to 70 degrees with respect to the horizontal plane) at the valley fold line b are formed. In addition, although the downward bending leg part 4b and the upward bending leg part 4c are each bend | folded diagonally, it can also be bent at right angle below and right above.

  A quadrangular hole 4d is formed in the central portion 4a of the cushioning material 4, and bending cuts 4e extending in a diagonal direction are formed at four corners of the hole 4d. Moreover, the uneven | corrugated | grooved part 4f extended in the length direction L is formed in the both ends of the width direction W of the center part 4a, respectively.

  The valley fold line b of the diagonally upward bent leg 4c of the cushioning material 4 is formed in the entire width direction W, and the mountain fold line a of the diagonally downward bent leg 4b is the valley fold of the diagonally upward bent leg 4c. It is formed between the slits 4g on both sides in the width direction W of the diagonally upward bent leg portion 4c outside the line b in the length direction L.

  Therefore, the diagonally downward bent leg portion 4b is formed at the intermediate portion in the width direction W of the central portion 4a, and the diagonally upward bent leg portion 4c is formed at both sides of the central portion 4a in the width direction W.

  The outer end of the diagonally downwardly bent leg 4b has a width slightly narrower than the length in the width direction W of the hook hole 3d of the packaging bag 3, and can be locked and fixed by inserting the hook hole 3d. A hook portion 4h is formed.

  The spacing length S between the hook holes 3d of the packaging bag 3 is such that the packaging bag 3 is slackened in the length direction L in a state in which the diagonally upward bent leg 4c of the cushioning material 4 is folded diagonally upward together with the diagonally downward bent leg 4b. However, after the hook hole 3d is locked and fixed to the hook portion 4h of the diagonally downward bent leg portion 4b, the hook portion 4h is bent when the diagonally downward bent leg portion 4b is bent diagonally downward as shown in FIG. The packaging bag 3 is set so as to be pulled (stretched) in the length direction L.

  If the packaging box 1 is configured as described above, the product 2 is stored in the packaging bag 3 from the opening 3b, while the diagonally upward bent leg 4c of the cushioning material 4 is folded diagonally upward together with the diagonally downward bent leg 4b. In this state, the hook hole 3d is locked and fixed to the hook portion 4h of the diagonally bent leg portion 4b while the packaging bag 3 is slackened in the length direction L, and thereafter, as shown in FIG. The downward bending leg 4b is bent obliquely downward. As a result, the packaging bag 3 is pulled (stretched) in the length direction L between the hook portions 4h of the diagonally downward bent leg portions 4b of the cushioning material 4. At this time, the product 2 stored in the packaging bag 3 is positioned on the upper surface of the central portion 4 a of the cushioning material 4.

  In this state, as shown in FIG. 4 (b), the cushioning material 4 is fitted into the packaging box 1, and the lower end of the diagonally downwardly bent leg 4 b is positioned near the lower corner 1 c in the packaging box 1. When the upper end of the diagonally upward bent leg 4c is positioned near the upper corner 1d in the packing box 1, the diagonally downward bent leg 4b and the diagonally upward bent leg 4c of the cushioning material 4 are packed. The product 2 stored in the packaging bag 3 is held in the vicinity of the central portion 4 a of the cushioning material 4 so as to be stretched at the upper and lower four corners in the box 1. If the product 2 is a lightweight product, the cushioning material 4 is fitted into the packing box 1 in the 90 ° sideways state, and the lower end of the diagonally downwardly bent leg 4b is placed on one side of the packing box 1. While being positioned near the side corners, the upper ends of the diagonally upward bent legs 4c can be positioned near the other side corners in the packaging box 1, respectively.

  At this time, since the cushioning material 4 has elasticity, even if an impact such as a drop acts on the packaging box 1, the elasticity of the diagonally downward bent leg 4b and the diagonally upward bent leg 4c and the elasticity of the central part 4a are used. The impact from the packaging box 1 is not easily transmitted to the product 2. Further, since the flexible packaging bag 3 is pulled and fixed in the length direction L by the diagonally downward bent leg 4b, the diagonally downward bent leg 4b, the diagonally upward bent leg 4c, and The impact from the central portion 4a is not easily transmitted to the product 2.

  In addition, the cushioning material 4 can be configured by folding one sheet at the time of use, and since only a separate packaging bag 3 is provided, the structure is simple and the cost is low, and it can be folded flat when not in use. If the cushioning material 4 is made of a corrugated cardboard sheet, it is not bulky, and processing such as incineration after discarding does not affect the environment. Furthermore, since the product 2 is stored in the packaging bag 3, there is no possibility that dust or the like will adhere.

  Further, the product 2 can be positioned at the intermediate portion of the central portion 4a in the width direction W by forming the diagonally downward bent leg portion 4b at the intermediate portion in the width direction W of the central portion 4a, and the diagonally upward bent leg. By forming the portions 4c on both sides in the width direction W of the central portion 4a, the cushioning material 4 can be evenly stretched at the four corners in the packing box 1 so that the product 2 can be held near the central portion 4a. Become.

  Furthermore, since the opening 3b is formed only at one end side in the length direction L of the packaging bag 3, the hook hole of the packaging bag 3 containing the product 2 is accommodated in the hook portion 4h of the diagonally downward folding leg portion 4b before folding. When 3d is respectively fixed and the diagonally downward bent leg portion 4b is bent diagonally downward, the packaging bag 3 is pulled in the length direction L, so that the packaging bag 3 is strongly attached to the bent edge 4i of the diagonally downward bent leg portion 4b. It comes to be pressed. Therefore, the packaging bag 3 containing the product 2 from the opening 3b is naturally sealed by pressing the opening 3b strongly against the bent edge 4i, so that it is not necessary to seal it in advance. Further, when the cushioning material 4 is taken out from the packaging box 1 and the packaging bag 3 is removed from the hook portion 4h of the diagonally downwardly bent leg 4b, the sealing on the opening 3b side is naturally released. Can be taken out smoothly.

  In addition, hook holes 3d are formed at both ends of the packaging bag 3, and hook portions 4h for locking and fixing the hook holes 3d of the packaging bag 3 are formed on the diagonally downward bent leg portions 4b of the cushioning material 4. By simply locking the hook hole 3d of the packaging bag 3 to the hook portion 4h of the diagonally downwardly bent leg portion 4b of the cushioning material 4, both ends of the packaging bag 3 can be fixed to the diagonally downwardly bent leg portion 4b. become. In addition, in order to fix the both ends of the packaging bag 3 to the diagonally downward bent leg portion 4b, it can be fixed by bonding with an adhesive instead of the hook hole 3d and the hook portion 4h.

  Further, since the bending cut portion 4e is formed in the central portion 4a of the buffer material 4, the elasticity of the central portion 4a of the buffer material 4 is increased by the bending cut portion 4e, so that the impact from the central portion 4a is caused by the product 2. It becomes difficult to be transmitted.

  Moreover, since the uneven part 4f was formed in the both ends of the width direction of the center part 4a of the buffer material 4, even if the impact of the width direction W acts on the packaging box 1, the uneven part of the center part 4a of the buffer material 4 Since the impact is weakened when 4f collides with the inner surface of the packaging box 1 and is crushed, the impact in the width direction W from the packaging box 1 is hardly transmitted to the product 2. In addition, as for the uneven | corrugated | grooved part 4f, the thing of the shape which protrudes outward from the both ends of the width direction W of the center part 4a like FIG.2 (c) is preferable. If it does in this way, since the uneven | corrugated | grooved part 4f will collide with the inner surface of the packaging box 1 and it will be easy to be crushed, an impact will become weaker.

  In the above embodiment, the product 2 is drawn in a rectangular parallelepiped shape. However, as long as the outer shape approximates, the product 2 may be uneven or inclined as shown in FIG. In short, any outer shape may be used as long as it can be stored in the packaging bag 3.
