Description:
FIELD OF THE INVENTION  
         [0001]    The present invention relates to a stereoscopic inner spacer, and more particularly, to a stereoscopic inner spacer used to support and hold an object securely in a packaging carton, thereby protecting the object from impacts, and the application of the stereoscopic inner spacer is not limited to the present field.  
         BACKGROUND OF THE INVENTION  
         [0002]    Protective packaging structures are used for supporting objects deposited within the packaging structures to protect the objects from impacts, water, and shaking. Generally, the materials forming the protective packaging structures are often selected from papers, plastics, and metals. Due to the advantages of easy printing and fabricating, and low technique threshold and cost, the protective packaging structures made of paper are widely applied in various aspects of daily life. However, the impact-resistibility and water-resistibility of the paper packing structures are insufficient during loading, transporting, and unloading. Particularly, while transporting the computers and related devices thereof, dust-proof, anti-pollution, and shockproof are needed even more, therefore, additional inner spacer, papers or plastics lining materials, foamed plastic filler, or foamed cushioning pad are added to protect the objects within the packaging structures from shaking.  
           [0003]    Recently, with the promoting of the environmental protection awakening, the inner spacer made of paper has advantages of low cost of fabricating, storing, and transporting; being able to be made by using primitive paper pulp or reprocessed paper pulp; and good performance of printing, and especially the other materials need to bear the cost of recycle lately, so that the paper inner spacer has more powerful competitiveness. The formation of the paper inner spacer can be performed mainly in two methods: The first method is to form the paper inner spacer by directly hot pressing paper pulp into a mold, and the second method is to design and cut paper sheets to form various different inner spacers. The second method is performed first by sampling and drawing parallel lines according to the size of the required object, and then by folding and pasting according to the required style so as to fabricate the inner spacer required.  
           [0004]    However, the method of forming the paper inner spacer by directly hot pressing paper pulp into a mold needs to develop and fabricate the mold, so that the cost is increased due to the expense of fabricating the mold, and additionally, the inner spacer made by folding and pasting paper sheets has the drawbacks of poor impact-resistibility and needing to use adhesive. Therefore, it is necessary to provide a better stereoscopic inner spacer to support and hold objects securely deposited in a packaging carton for protecting the objects from impacts.  
         SUMMARY OF THE INVENTION  
         [0005]    In view of the drawbacks of the conventional technique, therefore, one major object of the present invention is to provide a stereoscopic inner spacer made by folding and crossing paper materials to form the new structure of stereoscopic inner spacer to support and hold objects securely deposited within a packaging carton, thereby protecting the objects from impacts. Comparing to the conventional techniques, the present invention, does not need to develop and fabricate molds thereby saving the cost of making the molds; avoids the poor impact-resistibility of the inner spacer made by folding and pasting paper sheets; and does not need to use adhesive.  
           [0006]    The other object of the present invention is to provide a stereoscopic inner spacer, which is formed by folding and crossing paper materials for supporting and holding objects deposited securely within a packaging carton.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0026]    The present invention provides a stereoscopic inner spacer made by folding and crossing paper materials to support and hold objects securely deposited within a packaging carton, thereby protecting the objects from impacts. The following description is an embodiment of achieving the stereoscopic inner spacer and the sizes of all portions of the stereoscopic inner spacer according to the present invention, and is merely stated as an illustration for explaining the present invention rather than as a limitation of the present invention.  
         [0027]    Referring to FIG. 1, FIG. 1 illustrates a diagram showing an unfolded stereoscopic inner spacer of the present invention. The stereoscopic inner spacer  10  of the present invention is used to support and hold objects securely deposited within a packaging carton. The material of the stereoscopic inner spacer  10  is preferably selected from a paper material having a buffer layer in the middle, and the specific examples related to the material are corrugated paper and bond paper, etc. The stereoscopic inner spacer  10  comprises: an upper panel  11 , wherein the upper panel  11  includes relatively a left side portion  13 , a right side portion  15 , and a rear side portion  17 , and a fold line  19  is formed on the borders of the upper panel  11  respectively adjacent to the left side portion  13 , the right side portion  15 , and the rear side portion  17 . The left side portion  13  and the right side portion  15  are disposed on the opposite sides of the upper panel  11 , and the rear side portion  17  is disposed between the left side portion  13  and the right side portion  15 . The size of the upper panel  11  depends on the internal size of a carton body  110  of a packaging carton  100  (shown in FIG. 3), and a rectangle  20  is defined on the upper panel  11 , wherein the size of the rectangle  20  depends on the object deposited thereon, and the rectangle  20  is segmented to form an inserting slice  22 , an inserting slice  24 , an inserting slice  26 , and an inserting slice  28 , thereby forming an open space  30  to deposit a component (such as a computer device) that is smaller than the packaging carton  100 .  
         [0028]    The left side portion  13  includes a left side panel  14 , a front reinforced slice  31 , and a rear reinforced slice  33 , wherein a fold line  19  is formed between the left side panel  14  and the upper panel  11 ; a fold line  35  is formed between the front reinforced slice  31  and the left side panel  14 ; and a groove  39  is implemented on the appropriate place on the front reinforced slice  31 . A fold line  37  is formed between the rear reinforced slice  33  and the left side panel  14 , and a groove  40  is implemented on the appropriate position of the rear reinforced slice  33 . Besides, the left side portion  13  further has a left extending portion  45 , wherein a fold line  43  is formed between the left extending portion  45  and the rear reinforced slice  33 .  
         [0029]    The right side portion  15  includes a right side panel  16 , a front reinforced slice  32 , and a rear reinforced slice  34 , wherein the fold line  19  is formed between the right side panel  16  and the upper panel  11 ; the fold line  35  is formed between the front reinforced slice  32  and the right side panel  16 ; and a groove  41  is implemented on the appropriate position of the front reinforced slice  32 . The fold line  37  is formed between the rear reinforced slice  34  and the right side panel  16 , and a groove  42  is implemented on the appropriate position of the rear reinforced slice  34 .  
         [0030]    A feature of the present invention is to connect the front reinforced slice  31  and the front reinforced slice  32 , and to connect the rear reinforced slice  33  and the rear reinforced slice  34  by folding the fold line  19  and the fold line  35 ; crossing the groove  39  and the groove  41 ; folding the fold line  37 ; and crossing the groove  40  and the groove  42 , so as to form a hollow rectangle cuboid. The hollow rectangle cuboid not only is used to support the bottom panel  51 , but also has a better impact-resistibility, thereby providing a better cushioning effect. For example, a stereoscopic inner spacer of a preferred embodiment of the present invention can sustain an impact caused by the 50-grams stereoscopic inner spacer falling from a height of 90 centimeters with a velocity of 11 meters per second.  
         [0031]    Because the groove  39  and the groove  41  are used to cross the front reinforced slice  31  and the front reinforced slice  32 , and the groove  40  and the groove  42  are used to cross the rear reinforced slice  33  and the rear reinforced slice  34 , therefore, another feature of the present invention is that the directions of the groove  39 , the groove  40 , the groove  41 , and the groove  42  are not limited. For example, the groove  39 , the groove  40 , the groove  41 , and the groove  42  in FIG. 3 are all open to the left, but the groove  39 , the groove  40 , the groove  41 , and the groove  42  of the stereoscopic inner spacer of the present invention can also be open to the right.  
         [0032]    The rear side portion  17  includes a rear side panel  18 , a bottom panel  51 , and a rear connecting portion  53 , wherein a fold line  55  is formed between the bottom panel  51  and the rear side panel  18 ; and an inserted socket  62 , an inserted socket  64 , an inserted socket  66 , and an inserted socket  68  corresponding to the inserting slice  22 , the inserting slice  24 , the inserting slice  26 , and the inserting slice  28  are formed on the bottom panel  51 , so as to plug the inserting slice  22 , the inserting slice  24 , the inserting slice  26 , and the inserting slice  28  into the inserted socket  62 , the inserted socket  64 , the inserted socket  66 , and the inserted socket  68  correspondingly, thereby forming the open space  30  shown in FIG. 2. By folding the fold line  55  of the rear side portion  17 , the bottom panel  51  is parallel to the upper panel  11 .  
         [0033]    A fold line  57  is formed between the rear connecting portion  53  and the bottom panel  51 . By folding the fold line  57  of the rear connecting portion  53 , the rear connecting portion  53  is parallel to a side of the mutually crossed front reinforced slices  31  and  32 , thereby supporting the bottom panel  51 .  
         [0034]    It is deserved to be mentioned that the present invention discloses the stereoscopic inner spacer applied to support and hold an object securely deposited within a packing carton. Further expanding, the present invention folds and crosses paper materials to form a new structural stereoscopic inner spacer and forms an open space on the stereoscopic inner spacer to support and hold components having sizes smaller than that of a packaging carton, thereby protecting the components from impact. Furthermore, the present invention further can use adhesive to reinforce the structure of the stereoscopic inner spacer, wherein the sizes and the directions of the grooves described in the application are stated as an example. The grooves of other sizes and directions can further be applied in the present invention, and the sizes and the directions of the grooves are not limited to those described in the application. Because the change of the sizes and the directions of the grooves are known by a person skilled in this art, the related details are not stated herein.  
         [0035]    Referring to FIG. 1 and FIG. 2 simultaneously, FIG. 2 illustrates a 3-D assembly diagram showing a stereoscopic inner spacer of the present invention. The stereoscopic inner spacer  10  comprises an upper panel  11 , a left side portion  13 , a right side portion  15 , and a rear side portion  17 , wherein the upper panel  11  is further segmented to form an inserting slice  22 , an inserting slice  24 , an inserting slice  26 , and an inserting slice  28 , thereby forming an open space  30  to expose part of a bottom panel  51 , such as the stereoscopic diagram shown in FIG. 2. A front reinforced slice  31  of the left side portion  13  and a front reinforced slice  32  of the right side portion  15  are connected by crossing. Additionally, the rear side portion  17  comprises the bottom panel  51 , and an inserted socket  62 , an inserted socket  64 , an inserted socket  66 , and an inserted socket  68  respectively corresponding to the inserting slice  22 , the inserting slice  24 , the inserting slice  26 , and the inserting slice  28  are formed on the bottom panel  51 , so as to plug the inserting slice  22 , the inserting slice  24 , the inserting slice  26 , and the inserting slice  28  into the inserted socket  62 , the inserted socket  64 , the inserted socket  66 , and the inserted socket  68  correspondingly, thereby forming an open space  30 , wherein the inserting slice  22 , the inserting slice  24 , the inserting slice  26 , and the inserting slice  28  are used to hold an object securely.  
         [0036]    Besides the feature of providing the open space  30  to support and hold objects securely deposited within a packaging carton, another feature of the present invention is that the stereoscopic inner spacer  10  further provides a space  70 , a space  75 , a space  80 , and a space  90  that not only provide a cushioning effect but also are used to deposit wire materials or providing other uses, wherein the wire materials are, for example, power cord or signal transmission cord, etc.  
         [0037]    Referring to FIG. 1 and FIG. 3 simultaneously, FIG. 3 illustrates a 3-D diagram showing a stereoscopic inner spacer of the present invention deposited within a packaging carton. A packaging carton  100  comprises a lid  102  and a carton body  110 , wherein the lid  102  has a connecting portion  104 . The connecting portion  104  comprises a pair of side wing slices  106  that are located in two parallel sides of the connecting portion  104  and not connected to the lid  102 , and an upper wing slice  108  located in one side of the connecting portion  104  is perpendicular to the sides where the side wing slices  106  are located. Two plow grooves  112  implemented on the two vertical edges of a front side of the carton body  110  are used to be plugged with the side wing slices  106  correspondingly, thereby fastening the lid  102  on the carton body  110 . Another plow groove (not shown) implemented on a parallel edge of the front side of the carton body  110  is used to be plugged with the upper wing slice  108  correspondingly, thereby fastening the lid  102  on the carton body  110 . The stereoscopic inner spacer  10  is deposited within the carton body  110  of the packaging carton  100 , wherein the stereoscopic inner spacer  10  comprises an upper panel  11 , and the upper panel  11  further includes an open space  30  formed by segmenting the upper panel  11  to form an inserting slice  22 , an inserting slice  24 , an inserting slice  26 , and an inserting slice  28 , and the open space  30  exposes part of a bottom panel  51 , such as the 3-D diagram shown in FIG. 3. The open space  30  is used to deposit, for example, a computer device, a portable device (such as mobile phone or personal digital assistant, etc.) and fittings thereof.  
         [0038]    According to the aforementioned description, one advantage of the present invention is to provide a stereoscopic inner spacer made by folding and crossing paper materials to form the new structure of stereoscopic inner spacer to support and hold objects securely deposited within a packaging carton, thereby protecting the objects from impacts. Comparing to the conventional techniques, the present invention, does not need to develop and fabricate molds thereby saving the cost of making the molds; avoids the poor impact-resistibility of the inner spacer made by folding and pasting paper sheets; and does not need to use adhesive.  
         [0039]    Another advantage of the present invention is to provide a stereoscopic inner spacer, by folding and crossing paper materials to fabricate the stereoscopic inner spacer used to support and hold objects securely deposited within a packaging carton. The stereoscopic inner spacer of the present invention is fabricated without using adhesive, and conforms to the environmental protection standards widely adopted in Taiwan, Europe, America, Japan, and China, etc.
