Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Technical Field 
         [0002]    The present invention relates to a combination bag and, more particularly, to an innovative combination bag design featuring both usefulness and the fun of combination in which at least two pieces of face material are peripherally provided with zippers in order to make an easy-to-disassemble combination bag having a hollow interior for receiving objects. 
         [0003]    2. Description of Related Art 
         [0004]    Wallets, handbags, tote bags, suitcases, and so on are well known in the art, serving mainly to hold the user&#39;s personal items in their interior spaces so that a diversity of small objects can be carried around with ease. While their constructions and shapes vary with functions and applications, they are typically a single hollow structure with an open end, be they made of leather, plastic, canvas, or a composite material. Their looks and internal receiving spaces, therefore, are fixed and cannot be altered. In other words, their capacities cannot adapt to practical needs, nor are their dimensions changeable at will. 
       BRIEF SUMMARY OF THE INVENTION 
       [0005]    In view of the above, the present invention provides a novel combination bag as disclosed herein. 
         [0006]    The primary objective of the present invention is to provide a combination bag assembled from at least two pieces of face material which are peripherally provided with zippers so as to be joined together to form a hollow interior for receiving objects, or be easily disassembled when desired, thus featuring not only usefulness but also the fun of arbitrary combination. 
         [0007]    Another objective of the present invention is to provide a combination bag assembled from as many pieces of face material as necessary, wherein the plural pieces of face material are peripherally provided with zippers so as to be joined together to form a hollow interior for receiving objects, or be easily disassembled when desired. The internal receiving space and shape of the combination bag, therefore, can be changed. 
         [0008]    To achieve the foregoing objectives, the present invention adopts the following technical means. 
         [0009]    The combination bag of the present invention includes at least two pieces of face material and at least four zippers. 
         [0010]    The two pieces of face material are of the same shape. 
         [0011]    The four zippers are respectively provided on the peripheral sides of the two pieces of face material. 
         [0012]    By operating the slider of each zipper, all the zippers can be closed to join the two pieces of face material together such that the combination bag is formed and has a hollow interior for receiving objects. 
         [0013]    By opening one of the zippers, the combination bag is provided with an opening through which objects can be put into or taken out of the combination bag. 
         [0014]    As shown in the following embodiments of the present invention, more than two zipper-enclosed pieces of face material can be used to form combination bags featuring not only easy disassembly but also different internal receiving spaces and different shapes. 
         [0015]    Moreover, at least two of the at least two pieces of face material of the combination bag can be provided with a strap, which forms a handle or shoulder strap of the combination bag.

         [0055]    When one of the zippers  20  is opened, the opened zipper  20  forms an opening of the combination bag  10  such that objects can be put into or taken out of combination bag  10  through the opening. 
         [0056]    Refer to  FIG. 6  for a structural diagram of the sixth embodiment of the combination bag  10  of the present invention. 
         [0057]    The combination bag  10  in  FIG. 6  is composed of nineteen pieces of face material  11 , twenty-eight zippers  20 , and a strap  30 . 
         [0058]    All the pieces of face material  11  have the same shape, and the strap  30  is provided on two corresponding ones of the nineteen pieces of face material  11 , forming the handle or shoulder strap of the combination bag  10 . 
         [0059]    The strap  30  is adjustable in length or can be detached from the combination bag  10 . 
         [0060]    The twenty-eight zippers  20  are respectively provided on the lateral sides of the nineteen pieces of face material  11 . More specifically, the two halves of each zipper  20  are connected to two corresponding lateral sides of two adjacent pieces of face material 
         [0061]    By pulling the slider  21  of each zipper  20 , all the zippers  20  can be closed to join the nineteen pieces of face material  11  together, thus forming the combination bag  10 , which has a hollow interior for receiving objects. 
         [0062]    When one of the zippers  20  is opened, the opened zipper  20  forms an opening of the combination bag  10  such that objects can be put into or taken out of combination bag  10  through the opening. 
         [0063]    When manufacturing the combination bag  10  of the present invention, the face material can be of shapes other than that disclosed herein, with the lengths of the zippers changed correspondingly. More specifically, the square face material  11  used in the foregoing embodiments can be modified in shape while the fixed-length zippers  20  are replaced by zippers of corresponding lengths. 
         [0064]    For instance, a rectangular piece of face material can be used in place of two square pieces of face material in the foregoing embodiments, with the lengths of zippers changed correspondingly. Thus, the number of zippers can also be reduced in comparison with the number of the zippers  20  otherwise required. 
         [0065]    Alternatively, a rectangular piece of face material can be used in place of three square pieces of face material in the foregoing embodiments, with the lengths of zippers changed correspondingly. Thus, the number of zippers can be further reduced in comparison with the number of the zippers  20  otherwise required. 
         [0066]    Or, a rectangular piece of face material can be used in place of six square pieces of face material in the foregoing embodiments, with the lengths of zippers changed correspondingly. Thus, the number of zippers can be further reduced in comparison with the number of the zippers  20  otherwise required. 
         [0067]    As another alternative, a larger square piece of face material can be used in place of four square pieces of face material in the foregoing embodiments, with the lengths of zippers changed correspondingly. Thus, the number of zippers can also be reduced in comparison with the number of the zippers  20  otherwise required. 
         [0068]    The combination bag  10  of the present invention can be easily assembled and disassembled. Not only can the pieces of face material  11  (with or without the strap(s)  30 ) and the zippers  20  vary in number according to practical needs in order to form combination bags  10  with different internal receiving spaces and of different shapes, but also each piece of face material  11  of such a combination bag  10  can be rapidly detached when the bag is not in use. Thus, the aforementioned objective of providing a useful combination bag featuring the fun of arbitrary combination is attained. 
         [0069]    As can be known from the above, the embodiments of the present invention are indeed capable of achieving the expected functions and predetermined objectives, and the present invention has been disclosed in detail to enable a person skilled in the art to implement the invention according to the disclosure of this specification. It is understood, however, that the embodiments provided herein serve illustrative purposes only. All equivalent changes and modifications which do not depart from the spirit of the present invention should fall within the scope of the present invention.
