The engaging flap 57 is connected to the engaging lateral edge 52 and formed with an engaging slot 570.
The lateral walls 7, 6 are connected respectively to the connecting lateral edges 41, 51 of the front and rear walls 4, 5 along lateral folding lines (L3, L4)
The lateral wall 7 has an engaging side 71 opposite to the connecting lateral edge 41 of the front wall 4 and connected detachably to the engaging lateral edge 52 of the rear wall 5. In this embodiment, the engaging side 71 of the lateral wall 7 has an engaging tab 73 engaging detachably the engaging slot 570 in the engaging flap 57 of the rear wall 5 so as to maintain a relative position among the front and rear walls 4, 5, and the lateral wall 7, as shown in FIG. 4. The lateral wall 7 has a top side 74, and a bottom side 75 opposite to the top side 74 and having a width larger than that of the top side 74. The engaging side 71 of the lateral wall 7 further has an extension wall portion 72 connected thereto along an upright folding line (L7) and formed with a positioning slot 721 that extends along a middle portion of the upright folding line (L7) and that has an enlarged middle slot portion 7211, as shown in FIG. 3. The engaging flap 57 of the rear wall 5 extends through the positioning slot 721 in the extension wall portion 72. The engaging tab 73 of the lateral wall 7 is engagable fittingly within the enlarged middle slot portion 7211 of the positioning slot 721 in the extension wall portion 72 when the package box is unfolded, as shown in 2.
The lateral wall 6, similar to the lateral wall 7, has an engaging side 61 opposite to the connecting lateral edge 51 of the rear wall 5 and connected detachably to the engaging lateral edge 42 of the front wall 4. In this embodiment, the engaging side 61 of the lateral wall 6 has an engaging tab 63 engaging detachably the engaging slot 470 in the engaging flap 47 of the front wall 4 so as to maintain a relative position among the front and rear walls 4, 5, and the lateral wall 6. The lateral wall 6 has a top side 64, and a bottom side 65 opposite to the top side 64 and having a width larger than that of the top side 64. The engaging side 61 of the lateral wall 6 further has an extension wall portion 62 connected thereto along an upright folding line (L8) and formed with a positioning slot 621 that extends along a middle portion of the upright folding line (L8) and that has an enlarged middle slot portion 6211, as shown in FIG. 3. The engaging flap 47 of the front wall 4 extends through the positioning slot 621 in the extension wall portion 62. The engaging tab 63 of the lateral wall 6 is engagable fittingly within the enlarged middle slot portion 6211 of the positioning slot 621 in the extension wall portion 62 when the package box is unfolded, as shown in FIG. 2.
The package box further includes two reinforcing flaps 8, 9 connected respectively to bottom edges 66, 76 of the lateral walls 6, 7 along bottom folding lines (L10, L9) and overlying the bottom wall 3, as shown in FIGS. 3 and 4.
In such a configuration, the front and rear walls 4, 5, and the lateral walls 7, 6 cooperatively define an accommodating space 20 thereamong. In this embodiment, the package box is unitary, and is capable of being unfolded so as to allow the bottom wall 3, the lateral walls 6, 7 and the front and rear walls 4, 5 to be positioned on a plane, as shown in FIG. 2.
Referring further to FIG. 5, in actual use, the bundled electric wires 10 disposed in the accommodating space 20 in the package box can be securely anchored to the front and rear walls 4, 5 by two bonding straps 11 that pass through the holding holes 44, 54 in the front and rear walls 4, 5.
In sum, since the top side 64, 74 of each of the lateral walls 6, 7 is smaller than the bottom sides 65, 75 of the lateral walls 6, 7, the accommodating space 20 converges toward the top edges 43, 53 of the front and rear walls 4, 5, and the article can be easily limited in the accommodating space 20 in the package box. The package box of the present invention has an upper open side 21 such that the article disposed in the accommodating space 20 can be seen by consumers. The package box of this invention has a relatively large outer surface that includes outer surfaces of the front, rear, and lateral walls 4, 5, 6, 7 and that can be printed with pictures and advertisement relating to the article received in the package box. In order to place the package box in a limited space together with others for display, one of the lateral walls 6, 7 can be selected to face consumers as a result of its smaller area.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
