DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0030] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
[0031] The present invention discloses a folding box. The folding box uses reinforcement sheets to reinforce the strength of front and rear panels and side panels of the folding box. By the extension of the reinforcement sheets, the structural stability of the folding box can be maintained when the folding box is produced with thin cardboard and the area required for the preparation of the cardboard is reduced. The folding box is formed by folding the cardboard having preset indented fold lines, and comprises a polygonal bottom panel 10. Referring to to a quadrilateral bottom panel is illustrated as an example. Referring to to , an octagonal bottom panel is illustrated as an example.
[0032] As shown in to a front panel 21 and a rear panel 22 extend from a front edge 11 and a rear edge 12 of the polygonal bottom panel 10, respectively.
The polygonal bottom panel 10 has two side edges 13. At least one side panel 30 extends from each of the side edges 13. A foldable positioning piece 23 extends from an outer edge of each of the front and rear panels 21, 22. A first reinforcement sheet 40 is attached and connected to the positioning piece 23.
[0033] A foldable piece 31 extends from an outer edge of each of the two side panels 30. A second reinforcement sheet 50 is attached and connected to the foldable piece 31. As shown in the foldable piece 31 and the second reinforcement sheet 50 may 10332170_3 be folded and adhered to the inner side surface of the side panel 30. Preferably, a flap 311 extends from an edge of the foldable piece 31.
[0034] The folding box further includes auxiliary retaining pieces 32 located at a position adjacent to the two side panels 30 and the front and rear panels 21, 22, respectively. The flap 311 may be retained at an inner side surface of the corresponding auxiliary retaining piece 32. As shown in when the two side panels 30 and the two second reinforcement sheets 50 are respectively folded on top of the polygonal bottom panel 10, the auxiliary retaining pieces 32 are adhered to the inner side surfaces of the front and rear panels 21, 22, respectively, so that the folding box is in a flat half-folded state to save transportation and storage space.
[0035] In this embodiment, each of the auxiliary retaining pieces 32 is provided with a diagonal indented fold line 321. The diagonal indented fold line 321 extends from a lower edge of each of the front and rear panels 21, 22 to the center of an upper edge of each of the front and rear panels 21, 22. The front and rear panels 21 and 22 are simultaneously erected by the respective auxiliary retaining pieces 32, as shown in when the user folds the two side panels 30 upward. Each of the auxiliary retaining pieces 32 is diagonally folded along the diagonal indented fold line 321.
[0036] The front and rear panels 21, 22 and the two side panels 30 are respectively erected on the polygonal bottom panel 10 to jointly define an accommodation space therein. The positioning pieces 23 and the first reinforcement sheets 40 of the front and rear panels 21, 22 are folded inwardly to overlap the inner side surfaces of the corresponding auxiliary retaining pieces 32, so that the three-dimensional shape of the folding box is retained as shown in to complete the assembly of the folding box.
[0037] The structural design that the positioning pieces and the first reinforcement sheets of the front and rear panels are folded inwardly to overlap the inner side surfaces of the corresponding auxiliary retaining pieces is able to reinforce the strength of the front and rear panels and the side panels when the folding box is made of the thin cardboard under environmental considerations. When the side panels of the folding box are pressed, it is possible to prevent a collapse through two sides of the first reinforcement sheets to hold against the side panels. The present invention has the advantages of reducing the material cost, environmental protection and structural stability. 10332170_3
[0038] illustrates a second embodiment of the folding box. The difference between the first embodiment and the second embodiment is the preset position of the second reinforcement sheet 50. In the first embodiment, the second reinforcement sheet 50 is disposed on the foldable piece 31. In the second embodiment, the second reinforcement sheet 50 is disposed on the side panel 30.
[0039] Furthermore, as shown in the area of each positioning piece 23 may be less than the area of each of the front and rear panels 21, 22. The positioning piece 23 is connected with the first reinforcement sheet 40 to extend outwardly and to have an area about equal to the area of each of the front and rear panels 21, 22. Such a structure may be applied to the foldable piece 31 and the side panel 30, and the area required for the preparation of the cardboard may be reduced. Thus, the folding box of the first embodiment may be made with the thin cardboard, and the area required for the preparation of the cardboard may be reduced to save the material cost.
[0040] illustrates a third embodiment of the folding box. The difference between the second embodiment and the third embodiment is that the area of the first reinforcement sheet 40 is less than the area of each of the front and rear panels 21, 22 or the area of the positioning piece 23; and that the area of the second reinforcement sheet 50 is less than the area of each of the side panels 23 or the area of the foldable piece 31.
Similarly, the folding box can be assembled firm, and the area required for the preparation of the reinforcement sheet may be reduced. The folding box of the present invention saves the material cost and is an environment-friendly product.
[0041] Referring to to , an octagonal bottom panel 10 is illustrated.
The arrangement and structure of the front and rear panels 21, 22, the side panels 30, the positioning pieces 23, the foldable pieces 31, the first reinforcement pieces 40, and the second reinforcement pieces 50 are substantially similar to the aforesaid embodiments.
The following only shows the difference:
[0042] As shown in the drawings, a plurality of connected side panels 30 are provided at the same side edge 13 of the polygonal bottom panel 10. The bottom edge of the side panel 30A adjacent to each of the front and rear panels 21, 22 is provided with a connecting piece 33 extending to the brim of the polygonal bottom panel 10. The connecting piece 33 is provided with an indented fold line 331 and can be folded up along 10332170_3 the indented fold line 331, such that each side panel 30 can be erected upwardly on the polygonal bottom panel 10.
[0043] After the front and rear panels 21, 22 and the plurality of side panels 30 are respectively erected on the polygonal bottom panel 10, the auxiliary retaining pieces 32 are adhered to the inner side surfaces of the front and rear panels 21, 22. After that, the positioning pieces 23 and the first reinforcement sheets 40 of the front and rear panels 21, 22 are folded inwardly to overlap the inner side surfaces of the corresponding auxiliary retaining pieces 32, so that the three-dimensional shape of the folding box is retained to complete the assembly of the octagonal folding box.
[0044] The present invention is suitable for a folding box having a polygonal bottom panel 10 with even-numbered edges, but does not exclude a folding box having a polygonal bottom panel 10 with odd-numbered edges.
[0045] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention.
Accordingly, the present invention is not to be limited except as by the appended claims.
