Combination bag

Abstract

A combination bag includes at least two pieces of face material and at least four zippers. The two pieces of face material are of the same shape and have a zipper on each of their peripheral sides. By operating the slider of each zipper, all the zippers can be closed to join the two pieces of face material together, forming a combination bag with a hollow interior for receiving objects. 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. A plurality of such zipper-enclosed pieces of face material can make combination bags featuring not only easy disassembly but also different internal receiving spaces and different shapes.

What is claimed is: 
     
         1 . A combination bag, comprising:
 at least two pieces of face material of a same shape; and   at least four zippers respectively provided on peripheral sides of the at least two pieces of face material, wherein each said zipper has two halves respectively connected to two corresponding said lateral sides of two adjacent said pieces of face material;   wherein by operating a slider of each said zipper, all the zippers can be closed to join the at least two pieces of face material together such that the combination bag is formed and has a hollow interior for receiving objects, and when one of the zippers is opened, the opened zipper forms an opening of the combination bag such that objects can be put into or taken out of the combination bag through the opening.   
     
     
         2 . The combination bag of  claim 1 , wherein two corresponding ones of the at least two pieces of face material are provided with a strap, and the strap has an end connected to a surface of one of the two corresponding pieces of face material and an opposite end connected to a surface of the other of the two corresponding pieces of face material such that the strap forms a shoulder strap or handle of the combination bag. 
     
     
         3 . The combination bag of  claim 1 , wherein four corresponding ones of the at least two pieces of face material are provided with two straps, and the straps form shoulder straps or handles of the combination bag. 
     
     
         4 . The combination bag of  claim 1 , wherein large pieces of face material can be used in place of small pieces of face material, and the zippers can be changed in length according to the pieces of face material in use so as to be reduced in number. 
     
     
         5 . A combination bag, comprising:
 a plurality of pieces of face material of a same shape or different shapes;   a plurality of zippers respectively provided on peripheral sides of the plurality of pieces of face material, wherein each said zipper has two halves respectively connected to two corresponding said lateral sides of two adjacent said pieces of face material; and   at least one strap having an end connected to a surface of one of the plurality of pieces of face material and an opposite end connected to a surface of a corresponding one of the plurality of pieces of face material;   wherein by operating a slider of each said zipper, all the zippers can be closed to join the plurality of pieces of face material together such that the combination bag is formed and has a hollow interior for receiving objects, and when one of the zippers is opened, the opened zipper forms an opening of the combination bag such that objects can be put into or taken out of the combination bag through the opening.
