Packing box structure
A packing box includes a first triangular lateral board part, an upper board part, a bottom board part, a covering board part, and a second triangular lateral board part, which includes upper and lower parts; when the packing box is in a spread-out position, it has a first sticking plate lying between the first triangular lateral board part and the bottom board part; the first sticking plate joins the first triangular lateral board part and the bottom board part together, and therefore can prevent the covering board part from being folded along a middle portion when one is folding and erecting the packing box; therefore, folds won't be formed on the covering board part to spoil the appearance.
1. Field of the Invention
The present invention relates to a packing box structure, more particularly one, which is triangular and used to package a triangular object, and which is structured in such a manner that its covering board part won't be folded when it is folded and erected for use; thus, folds can't form on the covering board part to spoil the appearance.
2. Brief Description of the Prior Art
Referring to
The packing box 2 is assembled and erected for use according to the following steps:
Firstly, referring to
Secondly, referring to
Finally, referring to
The above-mentioned packing box has a drawback: when the box is folded and erected for use, the first triangular lateral board part has to be folded along the middle line in order for both the short sides of the first lateral board part to be close to each other, and in order for the upper board part to be stuck on the first sticking plate, and for the second upper lateral board part to be stuck on the third sticking plate; the covering board part will be inevitably folded at the same time. Consequently, folds form on the covering board part to spoil the appearance, and the packing box is unpleasant-looking.
Therefore, it is a main object of the present invention to provide an improvement on a packing box to overcome the above problem.
SUMMARY OF THE INVENTIONA packing box in accordance with an embodiment of the present invention has a first triangular lateral board part, an upper board part, a bottom board part, and a covering board part. Furthermore, when the packing box is in a spread-out state, it has a first sticking plate lying between the first triangular lateral board part and the bottom board part; the first sticking plate is used to join the first triangular lateral board part and bottom board part together, and therefore prevents folds from forming on the covering board part in folding and erecting the packing box. Therefore, folds won't be formed on the covering board part to spoil the appearance.
The present invention will be better understood by referring to the accompanying drawings, wherein:
Shown in
a first triangular lateral board part 11, which has a long side, and first and second short sides;
a covering board part 12 adjoining the long side of the first lateral board part 11; the covering board part 12 has an observation window 121 on a middle portion thereof; a transparent sticker can be fixed over the observation window 121;
a first sticking plate 13 adjoining the first short side of the first lateral board part 11; the first sticking plate 13 has a middle fold line 131, which divides the first sticking plate 13 into an outer plate part 132 and an inner plate part 133;
an upper board part 14 adjoining the second short side of the first lateral board part 11; the upper board part 14 has a second sticking plate 141 adjoining thereon, which is used to join the covering board part 12 and the upper board part 14 together;
a bottom board part 15 adjoining a lower end of the upper board part 14; the above-mentioned first sticking plate 13 is used to join the first triangular lateral board part 11 and bottom board part 15 together; a gap 150 is formed between one side of the bottom board part 15 and the inner plate part 133 of the first sticking plate 13; the bottom board part 15 has a third sticking plate 151 adjoining thereon, which is used to join the bottom board part 15 and the covering board part 12 together;
a second triangular upper lateral board part 16 adjoining an edge of the upper board part 14;
a third sticking plate 161, which adjoins the second upper lateral board part 16, and is used to join the covering board part 12 and the second upper lateral board part 16 together;
a second triangular lower lateral board part 17 adjoining an edge of the bottom board part 15;
a fourth sticking plate 171, which adjoins the second lower lateral board part 17, and is used to join the second lower lateral board part 17 and the covering board part 12 together; and
a fifth sticking plate 18, which is interposed between and joined on the second upper lateral board part 16 and the second lower lateral board part 17; the fifth sticking plate 18 has a middle fold line 181, which divides the fifth sticking plate 18 into an outer plate part 182 and an inner plate part 183.
The packing box 1 is folded and erected to become usable according to the following steps:
Firstly, referring to
Secondly, referring to
Thirdly, referring to
Fourthly, referring to
Finally, referring to
From the above description, it can be seen that the packing box of the present invention has an advantage over the prior art:
When the packing box is in the spread-out state, it has the first sticking plate lying between the first lateral board part and the bottom board part, which prevents the covering board part from being folded along a middle portion when the packing box is being folded and erected to change from the spread-out not-in-use position to the in-sue one. Therefore, folds won't be formed on the covering board part to spoil the appearance of the packing box. Consequently, the packing box of the present invention is more pleasant-looking and worth more money than the prior art.
Claims
