  However, the packaging box as described above requires a lot of fixing tools such as staples and joint tools for sealing, which not only requires time and cost for packing, but also takes time for unpacking and dismantling. is there.

  Therefore, an object of the present invention is to provide a packaging box that can be sealed with a small number of fixtures and that can be easily unpacked and disassembled.

  In order to solve the above-mentioned problem, the packaging box according to the present invention forms a peripheral wall by continuously connecting a front plate, a side plate and a rear plate, and a front raising piece at the tip of a bottom plate extending from the lower end of the rear plate, Side raised pieces are arranged on both sides to form a tray part, a top flap is provided at the upper end of the peripheral wall, the side raised pieces are stacked on the lower side of the side plate, and the front raised pieces are stacked on the lower side of the front plate. It was decided to fix and seal the front piece with a joint tool.

  In addition, a longitudinal cut band is provided on the front plate, and when the front plate is cut by pulling the cut band, the front plate can be opened in a double-spread shape around the ridge line with the side plate.

  In the packaging box according to the present invention, the front raised piece and the side raised piece are continuously provided on the bottom plate extending from the rear plate, and the tray portion for receiving the product is integrally formed, and the front plate and the front raised piece are joined together. Therefore, it is possible to seal with a small number of joint tools without fixing with staples and the like, and the packaging cost can be reduced. Moreover, unpacking and taking out of the contents can be easily performed, and disassembly accompanying disposal can be easily performed.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  This packing box is made of corrugated cardboard used for packing a thin and large screen television such as liquid crystal or plasma. In the blank, as shown in FIG. The face plate 3 and the side plate 2 are successively provided, and the passage piece 4 is provided on the other side of the front plate 1.

  A bottom plate 5 is connected to the lower end of the rear plate 3, a front raising piece 6 is connected to the tip of the bottom plate 5, and side raising pieces 7 are connected to both sides. A top flap 8 is connected to the upper end of the side plate 2, and a top flap 9 is connected to the upper ends of the front plate 1 and the rear plate 3.

  Two joint holes 10 are provided in the lower part of the front plate 1, and two joint holes 10 are also provided in the front raising piece 6. A cut tape is affixed in the longitudinal direction as a tear strip 11 at the center of the front plate 1 and the top flap 9, and a notch of the cut start portion 12 is provided in the upper portion of the front plate 1. Two handle holes 13 are provided in an intermediate portion of the side plate 2.

  In order to assemble a blank as described above and pack a television as a product, the front plate 1, the pair of side plates 2 and the rear plate 3 are folded into a square tube as shown in FIG. The peripheral wall 15 is formed by being attached to the side plate 2 on the opposite side.

  Further, the front raising piece 6 and the side raising piece 7 are erected from the bottom plate 5 to form the tray portion 16, and the side raising piece 7 is provided on the lower inner side of the side plate 2 and the front raising piece 6 is provided on the lower outer side of the front plate 1. And the joint tool 14 is inserted into the matching joint hole 10 to fix the front plate 1 and the front raised piece 6.

  Then, with the top surface opened, the television is housed in a box, the top flaps 8 and 9 are overlapped, and fixed with an adhesive tape or a band.

  Thus, in the packaging box, the front raising piece 6 and the side raising piece 7 are connected to the bottom plate 5 extending from the rear plate 3 so as to integrally form the tray portion 16 for receiving the product. Since the front raising piece 6 is fixed and sealed with the joint tool 14, it can be sealed only by using two joint tools 14.

  On the other hand, to unpack the packaging box sealed as described above, after removing the joint tool 14 and releasing the fixation of the top flaps 8 and 9, as shown in FIG. Is pulled, the front plate 1 and the top flap 9 connected thereto are cut, and the front raising piece 6 is tilted forward.

  As a result, as shown in FIG. 4, the front plate 1 can be opened in the form of a double door with the ridge line with the side plate 2 as an axis, and the unpacking operation can be easily performed.

  In addition, a heavy-screen TV with a heavy weight can be easily taken out by pulling it out to the front with almost no lifting.

  And when discarding, it can be crushed flat and folded easily, and the dismantling work does not take time.

  In the above embodiment, a cut tape is attached to the back surface of the front plate 1 and the top flap 9 as the cut band 11, but the cut band 11 is a half cut line obtained by cutting the cardboard about half in the thickness direction, or a short cut line. It may be a perforation with intermittent cuts.

  Further, not in the central portion of the front plate 1 but on the both sides of the front plate 1 are provided with longitudinal tear bands along the ridge line with the side plate 2, the front plate 1 is cut by these tear bands, and the joint tool 14 is attached. Without removing the front plate 1, the front plate 1 and the front raising piece 6 may be tilted forward and unpacked.

  In addition, the peripheral wall 15 is a general square tube, but it may be handled as a polygonal tube such as an octagonal tube whose corners are chamfered to improve the handleability and the stacking strength.
