Hereinafter, a method for manufacturing a paper box having a wireless signal transmission element according to a preferred embodiment of the present invention will be described with reference to the drawings.

  First, as shown in FIG.1 and FIG.2, the molding die 100 is provided (step a, ie, metal mold | die provision process). In the present embodiment, the molding die 100 is preferably a molding net, and a plurality of meshes 110 are formed on the inner surface of the molding die 100.

  After step a, as shown in FIGS. 1 and 3, the pulp is filled into the molding die 100 until the pulp covers the inner surface of the molding die 100, and at the same time, these meshes are formed outside the molding die 100. A negative pressure is supplied into the molding die 100 through 110 (step b, ie, base layer forming step). Thereby, since the pulp is pressed against the inner surface of the molding die 100, the base layer 210 is formed on the inner surface of the molding die 100.

  After step b, as shown in FIGS. 1 and 4, the radio signal transmission element 300 is installed on the base layer 210 (step c, ie, radio signal transmission element installation process). In the present embodiment, the wireless signal transmission element 300 is preferably an RFID chip. The RFID chip may be a passive RFID or an active RFID. In the case of an active RFID, a power storage element that is electrically connected to the RFID and supplies power to the RFID is preferably provided over the base layer 210. The present invention is not limited to the aspect of the wireless signal transmission element 300. As an arrangement mode of the wireless signal transmission element 300, there may be a mode of being embedded in the base layer 210, a mode of being semi-buried in the base layer 210, or a mode of being provided on the surface of the base layer 210, but is not limited thereto.

  After step c, as shown in FIGS. 1 and 5, when the pulp is refilled into the mold 100 until the pulp covers the base layer 210, and the wireless signal transmission element 300 is semi-embedded in the base layer 210 or When provided on the surface of the base layer 210, the pulp is refilled into the molding die 100 until the pulp covers the wireless signal transmission element 300 (step d, that is, a box forming process). On the outside of the molding die 100, negative pressure is supplied into the molding die 100 through the mesh 110, whereby the pulp refilled in the molding die 100 is adsorbed on the surface of the base layer 210, and the base layer Combined with 210, a box 200 is formed. Thus, the radio signal transmission element 300 is embedded in the box body 200.

  After step d, as shown in FIGS. 1 and 6, a dehydrating mold 400 corresponding to the molding mold 100 is provided. Here, the outer contour of the dehydrating mold 400 corresponds to the inner contour of the molding mold 100. When the dewatering mold 400 is disposed in the molding mold 100, it is preferable that a retreat space is formed between the dehydrating mold 400 and the molding mold 100. The thickness D1 of the retreat space is 2 to 5 mm. In the present embodiment, it is preferable that the thickness D1 of the evacuation space is 3 mm. The dewatering mold 400 is arranged in the molding mold 100 and presses the box 200, thereby compressing the box 200 into the retreat space, that is, compressing the thickness D1 of the box 200 to 3 mm. Then, a part of the water contained in the box 200 is squeezed out and discharged from the mesh 110 in the molding die 100 (step e, ie, dehydration step). In the present embodiment, step e may be selectively repeated. Since the surface of the box 200 becomes smoother as the number of dehydrations increases, the number of repetitions of step e can be selected according to the usage mode of the box 200.

  After step e, as shown in FIG. 1 and FIG. 7, a hot press mold 500 is provided, and the dehydrated box 200 is taken out from the molding mold 100 and placed in the hot press mold 500. The box 200 is pressed by the mold 500 until the thickness reaches the predetermined thickness D2, and then the hot press mold 500 is continuously heated for a predetermined time, thereby adding the dehydrated box 200. Pressure is applied and heated, and the heating and pressing are stopped after a predetermined time has elapsed (step f, ie, drying step). In the present embodiment, the predetermined thickness D2 may be 1.1 to 1.5 mm, but is preferably 1.3 mm. And although it is preferable that the box 200 is heated to 120-190 degreeC, it is not limited to this.

  According to said method, the box 200 which has the radio | wireless signal transmission element 300 which concerns on this invention can be manufactured.

  According to the method for manufacturing a paper box having a wireless signal transmission element according to the present invention, an integrally formed box 200 as shown in FIG. 8 can be formed by pulp using a mold. Furthermore, by embedding the wireless signal transmission element 300 in the box body 200 in the process of molding the box body 200, the paper box having the wireless signal transmission element according to the present invention can be completed. Therefore, the wireless signal transmission element 300 does not fall off from the box body 200, and is not easily broken by an external force, and does not affect the appearance of the box body 200.

  In the present invention, the preferred embodiments have been disclosed as described above. However, the present invention is not limited to the present invention, and various modifications can be made within the scope shown in the claims, and different embodiments are provided. Embodiments obtained by appropriately combining the disclosed technical means are also included in the technical scope of the present invention.
