Abstract

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.

Description

    BACKGROUND OF THE INVENTION
  • 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 FIGS. 12 and 13, a triangular packing box 2 is used to package a triangular object; the packing box 2 includes a first triangular lateral board part 21, a covering board part 22, a bottom board part 23, an upper board part 25, and a second triangular lateral board part, which includes lower and upper board parts 24 and 26. FIG. 9 is a view of the packing box 2 in a spread-out state; the covering board part 22 has an observation window 221 on a middle portion thereof, and a transparent plate is stuck on the covering board part 22 to cover the observation window 22; the first triangular lateral board part 21 has a long side, and first and second short sides, and the long side adjoins the covering board part 22; the first short side of the first triangular lateral board part 21 adjoins the bottom board part 23; the bottom board part 23 has a first sticking plate 231 joined to one end thereof, which will be stuck on the upper board part 25 when the box 2 is assembled and erected; the bottom board part 23 has a second sticking plate 232 joined to other end thereof, which will be stuck on the covering board part 22 when the box 2 is assembled and erected; one side of the second triangular lower lateral board part 24 adjoins an outer side of the bottom board part 23, and third and fourth sticking plates 241 and 242 are joined to other two sides of the second triangular lower lateral board part 24 respectively; the third and the fourth sticking plates 241 and 242 will be stuck on the second triangular upper lateral board part 26, and the covering board part 22 respectively when the box 2 is assembled and erected; the upper board part 25 adjoins the second short side of the first lateral board part 21; the upper board part 25 has a fifth sticking plate 251 joined to one end thereof, which will be stuck on the covering board part 22 in assembly; the second triangular lower lateral board part 24 has a sixth sticking plate 261 joined to one end thereof, which will be stuck on the covering board part 22 in assembly.
  • The packing box 2 is assembled and erected for use according to the following steps:
  • Firstly, referring to FIGS. 10 and 11, the first sticking plate 231 of the bottom board part 23 and the third sticking plate 241 of the second lower lateral board part 24 are folded inwards, and glue is applied to the first and the third sticking plates 231 and 241. Next, the first lateral board part 21 is folded along a middle line so that both the short sides are close to each other in order for the upper board part 25 and the second upper lateral board part 26 to be stuck on the first sticking plate 231 and the third sticking plate 241 respectively.
  • Secondly, referring to FIG. 12, the box is expanded and erected by means of moving the upper board part 25 and the bottom board part 23 away from each other so that the first lateral board part 21, the bottom board part 23, the upper board part 25, the second upper lateral board part 26, and the second lower lateral board part 24 together define a holding room 27 of the packing box.
  • Finally, referring to FIG. 13, after things are put in the holding room 27, the covering board part 22 is moved so as to cover the holding room 27, with the second, the fourth, the fifth and the sixth sticking plates 232, 242, 251 and 261 being stuck to the covering board part 22. Therefore, the things are enclosed in the packing box.
  • 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 INVENTION
  • A 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.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Shown in FIG. 1 is a preferred embodiment 1 of a packing box of the present invention in a spread-out not-in-use position. The packing box 1 consists of:
  • 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 FIG. 2, the packing box 1 (in the spread-out state as shown in FIG. 1) is folded along a line between the first lateral board part 11 and the first sticking plate 13, a line between the upper board part 14 and the bottom board part 15, and the fold line 181 of the fifth sticking plate 18.
  • Secondly, referring to FIG. 3, glue is applied to the inner plate part 133 of the first sticking plate 13 as well as an outer side of the second lower lateral board part 17, and next the packing box is folded by means of moving the fifth sticking plate 18 towards the second lower lateral board part 17 so that the inner plate part 183 of the fifth sticking plate 18 is stuck to the outer side of the second lower lateral board part 17.
  • Thirdly, referring to FIGS. 4 and 5, the packing box is folded along the gap 150 formed between the bottom board part 15 and the first sticking plate 13 so that the bottom board part 15 is moved inwardly and stuck on the outer side of the inner plate part 133 of the first sticking plate 13.
  • Fourthly, referring to FIG. 6, the packing box is expanded and erected by means of moving the bottom board part 15 away from the upper board part 14, and the first sticking plate 13 is folded along the middle fold line 131 so that the inner side of the inner plate part 133 is closed to the inner side of the outer plate part 132. Therefore, the first lateral board part 11, the upper board part 14, the bottom board part 15, the second upper lateral board part 16, and the second lower lateral board part 17 together define a holding room 19 of the packing box, as shown in FIG. 7.
  • Finally, referring to FIG. 8, after things are put in the holding room 19, the covering board part 12 is moved so as to cover the holding room 19, with the second, the third, the fourth and the fifth sticking plates 141, 151, 161 and 171 being stuck to the covering board part 121. Therefore, the things are enclosed in the packing box.
  • 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.
