Description:
BACKGROUND OF THE INVENTION 
       [0001]    a) Field of the Invention 
         [0002]    The invention relates in general to a packaging material structure, and more particularly, to a hollow tube cushioning packaging material structure made from a paper material (including waste paper), plant fiber or paper pulp. 
         [0003]    b) Description of the Prior Art 
         [0004]    With the continual progress of technologies, common commercial daily electronic appliances, electronic devices, precision products or fragile products, in order to provide a more esthetic appearance and to protect the intactness of products, are packaged by harder packaging materials or packaging materials of better quality. During the production process of products, associated components need to be transported to reach down-stream manufacturers. To prevent damages caused by collision, vibration or extrusion, packages materials such as polystyrene foam and expandable polyethylene (EPE) generally referred to as foam paper are also adopted to secure products and to provide extra space to reduce impact. 
         [0005]    Cushioning materials made from the foregoing polystyrene foam and EPE generally referred to as foam paper are common conventional approaches. However, with the rise of environmental awareness, these conventional cushioning materials made from polystyrene foam and EPE generally referred to as foam paper are being gradually replaced or even banned. 
       SUMMARY OF THE INVENTION 
       [0006]    It is a primary object of the present invention to achieve objects of cushioning external impacts and recycling waste for environmental protection by hollow tubes made from paper pulp, paper materials or plant fiber, and particularly by hollow tubes drawn and made from paper pulp of waste paper. 
         [0007]    To achieve the above object, the present invention provides a hollow tube cushioning packaging material structure including a plurality of hollow tubes. The hollow tubes are crossed and stacked or juxtaposed to form a packaging material structure, which forms an accommodating space therein. 
         [0008]    According to an embodiment of the present invention, the accommodating space is formed by the hollow tubes in a surrounding manner. 
         [0009]    According to an embodiment of the present invention, the accommodating space is defined by the hollow tubes having different lengths. 
         [0010]    According to an embodiment of the present invention, the hollow tube cushioning packaging material structure further includes a plurality of cushioning tubes respectively installed in crevice spaces defined by the hollow tubes stacked and juxtaposed.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0024]    The above and other aspects of the invention will become better understood with regard to the following detailed description of the preferred but non-limiting embodiments in the disclosure to one having ordinary skill in the art. 
         [0025]    Structures, ratios and sizes in the drawings of the application are for illustrating the contents of the disclosure for one person having ordinary skill in the art to better understand and read the application, and are not to be construed as limitations to the implementation of the present invention and do not imply any substantial technical meanings. Any structural modifications, ratios changes or size adjustments, without affecting the effects and achievable objects of the present invention, are regarded within the scope of the technical contents disclosed by the present invention. Terms such as “one”, “two” and “up” used in the disclosure are descriptive for easy understanding, and are not to be construed as limitations to the implementation of the present invention. Without substantially altering the technical contents, changes or adjustments made to the relations of the terms are also encompassed within the implementation scope of the present invention. 
         [0026]      FIG. 1  and  FIG. 2  are a perspective schematic diagram and a perspective schematic diagram of a packaging material structure in a used state and holding an object according to an embodiment of the present invention. The present invention provides a hollow tube cushioning packaging material structure made from a paper material (including waste paper), plant fiber or paper pulp. The hollow tube cushioning packaging material structure mainly includes a plurality of hollow tubes  10  crossed and stacked or juxtaposed to form a packaging material structure  1 . The packaging material structure  1  forms at least one accommodating space  12 . In  FIG. 2 , the hollow tubes  10  are placed in a surrounding manner to define the accommodating space  12 , and so the depth and height of the accommodating space  12  may be determined by the length and the number of stacks of the hollow tubes  10 . For example, when an accommodated object  2  has a size of that of a laptop computer, the length of the hollow tubes  10  is first restrained when drawing the paper pulp. Alternatively, the hollow tubes  10  are drawn from the paper pulp to have a fixed length and then cut. The hollow tubes  10  are then stacked onto one another or juxtaposed and adhered to define the accommodating space  12  for accommodating the laptop computer. Thus, the hollow tubes  10  made from the paper pulp not only achieve the object of recycling waste for environmental protection, but also at the same time accomplishes the effect of cushioning external impacts through the arrangement of the hollow tubes  10 . 
         [0027]      FIG. 3  and  FIG. 4  are a perspective schematic diagram and a perspective schematic diagram of a packaging material structure in a used state and holding an object according to another embodiment of the present invention. The structure as well as achievable effect and object of the present invention are explained in the foregoing description. In addition to forming an accommodating space  12   a  by a crossing and stacked or juxtaposed arrangement of hollow tubes  10   a , the accommodating space  12   a  may also be formed by the hollow tubes  10   a  having different lengths. In the embodiment, a cell phone is held for example. In order to effectively protect a cell phone  3   a , the hollow tubes  10   a  are categorized into long hollow tubes  100   a  and short hollow tubes  102   a . The long hollow tubes  100   a  may be juxtaposed to form a lower portion, and the short hollow tubes  102   a  are used to define the accommodating space  12   a , in which the cell phone  3   a  can be held. It is known from the above that, a special packaging material structure  1   a  for smaller objects can be formed by using the hollow tubes  10   a  having different lengths. Thus, the hollow tubes  10   a  made from the paper pulp not only achieves the object of recycling waste for environmental protection, but also at the same time accomplishes the effect of cushioning external impacts through the arrangement of the hollow tubes  10   a.    
         [0028]      FIG. 5  shows a planar schematic diagram of a structure of cushioning tubes of the present invention. To further enhance the effect of object protection, the present invention further includes a plurality of cushioning tubes  14  made from paper pulp. The cushioning tubes  14  may be installed in the crevice spaces  16  defined by the plurality of hollow tubes  10  stacked and juxtaposed. With the cushioning tubes  14  additionally installed in the crevice spaces  16  between the hollow tubes  10 , the cushioning effect of the packaging material structure  1  (as shown in  FIG. 1 ) is effectively reinforced. It should be noted that, given that the functions of cushioning and protection are achieved, the hollow tubes  10  or the cushioning tubes  14  are not limited to tubes with a circular tubal cross section. For example, the hollow tubes  10  or the cushioning tubes  14  may be tubes with a triangular, rhombus or polygonal tubal cross section, and may have a diameter, thickness and firmness designed for cushioning and anti-collision requirements. 
         [0029]      FIG. 6  shows a perspective schematic diagram according to another preferred embodiment of the present invention. In this embodiment, the hollow tubes  10  having the same size are in a crossing and stacked arrangement, so as to effectively reinforce the cushioning effect of the packaging material structure  1  and enhance the object of object protection.  FIG. 7  shows a perspective schematic diagram according to another preferred embodiment. A plurality of hollow tubes  10  are juxtaposed and are stacked into multiple layers. A slip sheet  4  is placed between every two layers of the plurality of hollow tubes  10 . Using the slip sheets  4 , the stacking operation of the plurality of hollow tubes  10  as well as the cushioning tubes  14  (as shown in  FIG. 5 ) can be made easier. Further, an advertisement or an artistic pattern may be presented on the outermost slip sheet  4 . 
         [0030]    In addition to the foregoing embodiments,  FIG. 8  and  FIG. 9  are two other perspective schematic diagrams of preferred embodiments of the present invention. The packaging material structure  1  of these two different patterns are formed by hollow tubes  10  having different lengths, and are crossed and stacked according to the forms of products to form the required packaging material structure  1 , thereby effectively achieving the object of object protection and cushioning from impacts. 
         [0031]    While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
