Benefits of technology

[0008] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a packing box equipped with an airbag for shock-absorbing and a manufacturing method thereof, in which the airbag consisting of a plurality of air cells is integrally formed with an inner surface of the packing box by means of heat and pressure, instead of installing a separate shock-absorbing member in the packing box, and then air is injected into the airbag, wherein the air cells of the airbag have their own one-way valves, respectively, so the shock-absorbing function of the airbag can be continuously maintained even if some air cells are broken, and additionally support square bars are integrally formed with a lower surface of the packing box, thereby further absorbing impact applied to the packing box.

Problems solved by technology

However, in spite of superior utilities of the carton box, the carton box is very weak against external impact applied thereto.
Thus, if the carton box is dropped to the ground or strong external impact is applied to the carton box, external impact is directly transferred to articles contained in the carton box, so that the articles will be broken or damaged.
However, such Styrofoam used as the shock-absorbing member has a large volume, so it is inconvenient to produce and deliver the shock-absorbing member made of Styrofoam and it is cumbersome to retrieve the shock-absorbing member made of Styrofoam.
Furthermore, since the pecuniary profit is not expected, persons discard Styrofoam without reusing it, thereby causing environmental pollution.

embodiment 1

[0046] In order to obtain a damping member 15 by bonding the airbag 12 to the outer surface of the packing box member 11, the airbag 12 is placed on the upper surface of the packing box member 11 and heat (about 180° C.) and pressure (about 4 kgf / cm2) are applied to the upper surface of the airbag 12 by using a heating seal bar, thereby bonding the airbag 12 to the upper surface of the packing box member 11. Then, the packing box member 11 integrally formed with the airbag 12 is assembled in the form of a box, thereby obtaining the shock-absorbing packing box 1 as shown in FIG. 2.

embodiment 2

[0047] The manufacturing procedure of Embodiment 2 is identical to that of Embodiment 1, except that heat (about 200° C.) and pressure (about 5 kgf / cm2) are applied to the upper surface of the airbag 12 by using a heating seal bar.

embodiment 3

[0048] The manufacturing procedure of Embodiment 3 is identical to that of Embodiment 1, except that heat (about 250° C.) and pressure (about 6 kgf / cm2) are applied to the upper surface of the airbag 12 by using a heating seal bar.

[0049] Since the outer surface of the airbag 12 is made of a film including polyethylene and nylon, the film may serve as an adhesive so that the airbag 12 can be easily bonded to the outer surface of the packing box member 11 when heat and pressure are applied to the airbag 12. That is, the damping member 15 can be obtained by bonding the airbag 12 to the packing box member 11 using the heating seal bar, so that the shock-absorbing packing box 1 equipped with the airbag 12 having the rectangular structure can be obtained through the automation process.

[0050] The air cells of the airbag 12 are provided at upper center portions thereof with one-way valves, which allow air to be injected into the air cells and prevent air injected into the air cells from b...
