A handle plate protrusion 31 that protrudes toward the first side plate panel 52 is formed at the boundary between each handle plate 29 and the first side plate panel 52 adjacent thereto. Each handle plate protrusion 31 is partitioned by a U-shaped cut line 55 with respect to the corresponding first side plate panel 52 and connected to the handle plate 29.

  Thus, the ribbon box 20 is manufactured from the ribbon blank board 50 formed integrally.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, a pair of ribbon units (three-color ink ribbon unit and protective ribbon unit) 1 as shown in FIG. 2 and a ribbon blank plate 50 as shown in FIG. 4 are prepared. Next, each ribbon unit 1 is placed on the ribbon blank plate 50, that is, on the bottom plate panel 51 of the ribbon blank plate 50 (see FIGS. 5A, 5B, and 5C). In this case, the feeding bobbin 1 b and the take-up bobbin 1 c of each ribbon unit 1 are placed so as to be in positions corresponding to the respective through holes 28 formed in the first side plate panel 52.

  Next, each first side plate panel 52 of the ribbon blank plate 50 is bent with respect to the bottom plate panel 51, and the feeding bobbin 1 b and winding of each ribbon unit 1 are inserted into the through holes 28 formed in each first side plate panel 52. The bobbin 1c is fitted (see FIGS. 6A, 6B, and 6C). Thus, each ribbon unit 1 is separated from the bottom panel 51 and supported only by each through hole 28. In this case, the bottom plate protrusion 24 protrudes outward.

  Next, each second side plate panel 53 of the ribbon blank plate 50 is bent with respect to the bottom plate panel 51 to form a ribbon box 20 containing each ribbon unit 1 (FIGS. 7A, 7B, 7). c)). In this case, the neck portion 26 of each second side plate 23 is fitted into the corresponding concave portion 27 of the first side plate 22, and the corresponding first side plate 22 is fitted into the groove 26a.

In this case, the handle plate protrusion 31 protrudes outward and contacts the inner surface of the outer box 11. Thereby, it is possible to further restrict the movement of the ribbon box 20 in the outer box 11 in the horizontal direction.

  Thereafter, the upper surface flaps 44 of the outer box 11 are folded and closed, and the upper surface flaps 44 are pasted together with the adhesive tape 3 (see FIG. 9). In this case, the upper surface of the ribbon box 20, that is, the upper surface of the handle plate 29 comes into contact with the inner surface of the outer box 11 (the lower surface of the upper surface flap 44) (see FIG. 1). Thus, the ribbon box 20 can be restricted from moving in the vertical direction in the outer box 11. In this way, the pair of ribbon units 1 are packed in the packing body 10.

  By the way, the case where each ribbon unit 1 is taken out from the package 10 in which the pair of ribbon units 1 is packed will be described below. In this case, first, the adhesive tape 3 is peeled off to open the upper surface flap 44 (see FIG. 8).

  Next, the ribbon box 20 in which each ribbon unit 1 is stored is taken out from the outer box 11. In this case, the handle plate 29 that has been bent is first extended in the vertical direction (see FIGS. 7A, 7 </ b> B, and 7 </ b> C), and then each ribbon unit 1 is stored using the handle plate 29. The ribbon box 20 is lifted and removed.

  Next, the neck portion 26 of each second side plate 23 is removed from the concave portion 27 of each first side plate 22, and the first side plate 22 is removed from the groove 26a to open each folded second side plate panel 53 (FIG. 6). (See (a), (b), (c)).

  Thereafter, the folded first side plate panels 52 are opened (see FIGS. 5A, 5B, and 5C). As a result, the feeding bobbin 1b and the take-up bobbin 1c of each ribbon unit 1 are removed from each through hole 28 of each first side plate panel 52, and each ribbon unit 1 is mounted on the bottom plate panel 51 of the ribbon blank plate 50. Placed. In this way, each ribbon unit 1 can be easily taken out from the outer box 11.
