Description

  The present invention relates to a packaging container suitable for product transportation such as a data cartridge and a CD cartridge.

  The packaging containers of Patent Documents 1 and 2 have a cardboard outer box having an open top surface and a cardboard interior member housed in the outer box, and the product is divided into an outer box and an interior member. It is disclosed that the product is covered with heavy weight to protect the product from a drop impact or the like.

Japanese Utility Model Publication No. 58-125169 (Fig. 1) Japanese Patent Laying-Open No. 2004-319387 (FIG. 1)

  In order to improve the shock-absorbing property against a drop impact or the like, in the interior member of Patent Document 1, the corrugated cardboard is bent outward and overlapped inside and outside. In the interior member of Patent Document 2, a square cylindrical spacer formed by bending corrugated cardboard is continuously provided. In Patent Documents 1 and 2, it takes time to assemble the interior member, leading to an increase in cost of the packaging container.

  On the other hand, when the interior member is formed of corrugated cardboard having a honeycomb structure with high buffering properties, the assembly work of the interior member can be facilitated. In this interior member, as shown in FIG. 6, front and rear walls 22 and 23 and left and right walls 25 and 26 are connected to the front and rear ends and left and right ends of the bottom wall 21, respectively, and a lid wall 27 is connected to the rear end of the rear wall 23. Set it up. According to the interior member of this form, the front and rear walls 22 and 23 and the left and right walls 25 and 26 are valley-folded so as to stand at right angles with respect to the bottom wall 21, and the lid wall 27 is valley-folded with respect to the rear wall 23. Just assemble.

  This type of packaging container is set so that there is almost no gap between the product and the interior member and between the interior member and the outer box in order to prevent the product from vibrating in the packaging container during transportation. Is done. For this reason, in the packaging container provided with the interior member having the above honeycomb structure, it is very difficult to take out the product from the packaging container.

  As a countermeasure, in Patent Document 1, as shown in FIG. 1, it can be considered that the product is taken out by being housed in a packaging container in a state of being stacked on the product on the tape and pulling up the end of the tape. In this case, there is a problem in that the number of parts increases by the amount of the tape and the cost required for packaging increases. It is conceivable to break the outer box and take out the product, but this makes it impossible to reuse the packaging container.

  The interior member is formed by cutting from a large area of corrugated cardboard. However, the interior member of FIG. 6 increases the amount of corrugated cardboard that is cut and discarded wastefully, resulting in poor yield and high packaging costs.

  An object of the present invention is to provide a packaging container in which an internal product can be easily taken out without breaking the outer box and the packaging cost can be suppressed.

  As shown in FIG. 1, the present invention includes a rectangular outer box 3 whose upper surface is open and an interior member 5 accommodated in the outer box 3. The interior member 5 includes an interior body 10 that covers the top and bottom and front and back of the rectangular product 2, and a pair of left and right buffer plates 11 and 11 that are formed independently of the interior body 10 and cover the left and right of the product 2. As shown in FIG. 2, the interior body 10 is formed in a rectangular shape in the unfolded state, and the front and rear sides of the bottom wall 12 on which the product 2 is placed and the front and rear ends of the bottom wall 12 are foldably connected to each other. A pair of inner walls 13 and 15, and a lid wall 16 connected to one inner wall 15 so as to be foldable are provided. As shown in FIG. 5, the buffer plates 11 and 11 are respectively arranged in an upright state between the product 2 and the left and right inner surfaces of the box body 6 of the outer box 3. Here, the interior main body 10 should just be formed in the substantially rectangular shape by the expansion | deployment state.

  Specifically, the vertical height dimensions of the buffer plates 11 and 11 are set so as to be higher than the upper end portions of the inner walls 13 and 15 before and after the interior body 10 in a state of being arranged in the outer box 3.

  The interior member 5 is preferably a cardboard having a honeycomb structure as shown in FIG.

  According to the present invention, since the product 2 is double protected by the outer box 3 and the interior member 5, it is possible to reduce the damage of the product 2 during transportation.

  When the buffer plates 11 and 11 are gripped and pulled out of the outer box 3, a gap is formed between the product 2 and the inner surface of the outer box 3, so that the product 2 can be easily removed from the packaging container using this gap. Can be pulled out. Therefore, the product 2 can be easily taken out from the packaging container without breaking the outer box 3, and the workability at the time of unpacking is improved and the packaging container can be reused.

  Since the interior body 10 of the interior member 5 has a rectangular shape in the unfolded state, the interior body 10 can be efficiently cut out from the large-area corrugated raw material used as a material, and the yield is improved by that much, and the packaging cost is reduced. be able to.

  When the vertical height dimension of the buffer plates 11 and 11 is set higher than the upper end portions of the inner walls 13 and 15 before and after the interior body 5 in the state of being arranged in the outer box 3, the upper ends of the buffer plates 11 and 11 are set. It is convenient for grasping the part and pulling it out from the outer box 3. At that time, the buffer plates 11 and 11 may be sized so as not to obstruct the opening of the outer box 3.

  When the interior member 5 is a corrugated cardboard having a honeycomb structure, it is suitable for mass production, and damage to the product 2 during transportation can be more reliably reduced.

  The drawing shows an embodiment of a packaging container targeted by the present invention, and shows a case where three rectangular cartridge bundles (products) 2 shown in FIG. As shown in FIG. 3, the cartridge bundle 2 is one in which 10 data cartridges 1 are stacked back and forth and fixed with a belt T, and then shrink-wrapped with a heat-shrinkable film F.

  As shown in FIG. 1, the packaging container includes a rectangular outer box 3 having an open top surface and an interior member 5 accommodated in the outer box 3.
