       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of Invention 
         [0003]    The invention relates to a package box and, in particular, to a one-sheet folding package box. 
         [0004]    2. Description of Related Art 
         [0005]    Most mobile electronic products, such as laptop computers or mobile phones, have many accessory parts, such as the adapter, power cord, mouse, spare battery, etc. During the transportation, protecting paper or plastic materials are usually used for packaging in order to prevent collisions and damages by separating and supporting articles enclosed therein. 
         [0006]    With reference to  FIGS. 1 and 2 , an existing package box  100  includes a bottom portion  110 , two body portions  120 ,  130 , and two cover portions  140 ,  150 . 
         [0007]    The bottom portion  110  includes a first side  111  and a second side  112  of equal length and in parallel, a third side  113  and a fourth side  114  of equal length and in parallel, and two apertures  115  adjacent to the third and fourth sides  113 ,  114 . 
         [0008]    Each of the body portions  120 ,  130  includes a first height part  121 ,  131 , a box part  122 ,  132 , a second height part  123 ,  133 , and a folding part  124 ,  134 , respectively. The box part  122 ,  132  is provided with a long-striped aperture  125 ,  135  in the vicinity of the second height part  123 ,  133 . Each of the box parts  122 ,  132  is provided with a holding hole  126 ,  136 . A connecting part  127 ,  137  is formed between the second height part  123 ,  133  and the folding part  124 ,  134  for connecting to the aperture  115 . 
         [0009]    The folding part  124  of the box part  122  is divided by the aperture  125  into a first folding region  124 ′ and a second folding region  124 ″. The first folding region  124 ′ is folded inward, whereas the second folding region  124 ″ is folded outward. Both of them touch against the bottom portion  110 . The folding part  134  of the body portion  130  is folded inward. 
         [0010]    The second height part  123  of the body portion  120  and the second height part  133  of the body portion  130  define a placing room  160  for placing an article  170  therein. 
         [0011]    In the assembly, the two body portions  120 ,  130  have a U shape bending on the bottom portion  110 . 
         [0012]    The cover portion  140  includes a height part  141 , a cover part  142 , a connecting part  143 , and a holding hole  144 . The cover portion  140  is bent into the U shape, so that the hooking part  143  can fit into the apertures  125 ,  135  of the body portion  120 , thereby covering one part of the body portions  120 ,  130 . 
         [0013]    The cover portion  150  includes a height part  151 , a cover part  152 , a connecting part  153 , and several holding holes  154 . The body portion  150  is bent into the U shape, so that the hooking part  153  can fit into the apertures  125 ,  135  of the body portion  120 , thereby covering the other part of the body portions  120 ,  130  and the placing room  160 . Thus, the article  170  (e.g., battery of a laptop computer) is packaged therein. 
         [0014]    The existing package box  100  uses the placing room  160  among the second height part  123 ,  133  of the body portion and the cover part  152  of the cover portion  150  to accommodate the article  170 . This achieves the goal of supporting and protecting the article  170 . However, if the height of the article  170  is larger than the second height parts  123 ,  133  of the body portions  120 ,  130 , the height of second height parts  123 ,  133  has to be increased in order to fit, support and protect a large-size article  170 . Thus, the whole size of the package box has to be changed as well. 
         [0015]    Accordingly, this package box  100  can only be used on articles  170  of a specific size. Therefore, laptop computer batteries of different shapes cannot share the same package box. In this case, the production cost will be higher. 
       SUMMARY OF THE INVENTION 
       [0016]    An objective of the invention is to provide a package box to solve the problem that the existing package box can only accommodate articles of one size. Without changing the overall material use, a gap for deformation enables the invention to accommodate articles of larger sizes. Therefore, the material stacking can be reduced, thereby increasing the shipping quantity and lowering the production cost. 
         [0017]    Another objective of the invention is to provide a package box that utilizes the connection between an anti-break gap and an aperture of the article to provide the cushion effect and prevent collisions. 
         [0018]    The disclosed package box includes a bottom portion, two body portions, and a cover portion. 
         [0019]    The bottom portion includes a first side and a second side of equal length and in parallel, a third side and a fourth side of equal length and in parallel, and two apertures adjacent to the third and fourth sides. 
         [0020]    The body portions are connected to the third and fourth sides of the bottom portion, respectively. Each body portion includes a connecting aperture, a through aperture, and an upright region. Each body portion is bent and fixed to the aperture of the bottom portion. The through aperture is formed in the upright region. 
         [0021]    The cover portion includes a first cover and a second cover. The first cover is connected with the first side of the bottom portion. It includes a first hooking plate to fit into the connecting aperture of the body portion. The first cover, the two opposite connecting apertures, and the body portion define an empty room. The second cover is connected with the second side of the bottom portion. It includes a second hooking plate to fit into the connecting aperture and a gap formed at the center. The second cover, the two opposite connecting apertures, and the empty room defines a placing room. 
         [0022]    According to the invention, the gap of the cover portion can be pushed and deformed appropriately to accommodate an article of a larger size. It also provides stable support and protection. The total material is not increased. The invention can hold articles of different sizes. Therefore, it has the advantages of saving the material, increasing the shipping quantity in each cargo, and lowering the cost.

         [0040]    Please refer to  FIGS. 6 and 7 . An article  600  is inserted into the placing room  501 . The second cover  800  then covers the body portions  300 ,  400  to enclose the article  600  inside the placing room. If the height of the article  600  is larger than the height of the height part  810  of the second cover  800 , the gap  850  is pushed upward. In this way, the total material of the package box can be reduced while achieving the same packaging effect. The article  600  is still supported and protected as desired. 
         [0041]    In comparison with the existing package boxes that can hold only articles of one size, the disclosed package box can accommodate articles of different sizes. When the height of the article  600  is greater than the height of the height part  810  of the second cover  800 , the gap  850  is pushed and suitably deformed so that the article  600  is stably held inside the accessory box. If the height of the article  600  is comparable to the height of the height part  810  of the second cover  800 , the gap  850  is not pushed or deformed. The article is still stably packaged therein. Therefore, the disclosed package box can be used for articles  600  of different sizes without increasing its material. The size of the package box is not modified as the article size is changed. This can reduce the production cost. 
         [0042]    The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
