Title: Zippered bag

Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The present invention relates to a bag, and more particularly to a zippered bag. 
     2. Description of Related Art 
     In order to keep the goods carried on the body safe, the bags usually are provided with a device to close an opening thereof, such as buckle, Velcro, zipper, and so on. Zipper is the commonest device to close and open the opening of the bag. 
     The conventional bag is provided with the zipper on a side, usually the top side, thereof. When the zipper is unzipped, the opening of the bag is opened, and the user may put goods in the bag. When a size of a good is slightly smaller than the bag, the opening would be not wide enough for the good although the good may be received in the bag. 
     Besides, the bag with a big opening would be popular to user to put goods in the bag, or take goods out. Some bags are provided with a zipper extending on two or more sides of the bag. Such bag has a big opening as well as a long zipper, however, it could not prevent the zipper from being damaged when the user widen the opening of the bag. 
     BRIEF SUMMARY OF THE INVENTION 
     In view of the above, the primary objective of the present invention is to provide a zippered bag, which has a big opening for access of goods, and may protect the zipper when the user is widen the opening. 
     In order to achieve the objective of the present invention, the present invention provides a zippered bag including a bag member and a zipper. The bag member has a first side, a second side, which is connected to the first side, and an opening, which extends from the first side to the second side. The zipper is provided on the bag member at an edge of the opening, wherein the zipper has a first section on the first side and a second section on the second side; and an end of the first section is closer to a joining point of the first section and the second section than a middle portion of the first section. 
     With such design, the bag member would have a big opening extending from the first side to the second side. Beside, an end of the zipper is closer to the joining point of the first and the second sections than a middle portion of the first section, which means that the direction changes in the first section. It could prevent the zipper from being damaged while the opening is being widened.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  shows a zippered bag  1  of the first preferred embodiment of the present invention, which is a backpack, including a bag member  10  and a zipper  12 . 
     The bag member  10  has a firs side  10   a  and a second side  10   b,  and the first side  10   a  is connected to the second side  10   b.  The bag member  10  is provided with an opening extending from the first side  10   a  to the second side  10   b.    
     The zipper  12  is provided on the bag member  10  at an edge of the opening. The zipper  12  has a first section  12   b  on the first side  10   a,  and a second section  12   d  on the second side  10   b.  The zipper  12  has an end  12   a  on the first side  10   a,  and a joining point  12   d,  which is the point where the first section  12   b  is connected to the second section  12   d.  The end  12   a  of the first section  12   b  is closer to the joining point  12   d  than a middle portion of the first section  12   b.  In other words, the first section  12   b  of the zipper  12  goes in a circular direction, and the second section  12   d  is straight. 
     The zippered bag  1  of the first preferred embodiment has a big opening. When the first section  12   b  is unzipped, a portion of the first side  10   a,  within the first second  12   b,  could be flipped open to access small goods. When both the first second  12   b  and the second section  12   d  are unzipped, it could access large goods through the entire opening. It is noted that the first section  12   b  of the zipper  12  may go in any direction other than circular direction. 
       FIG. 2  shows a zippered bag  2  of the second preferred embodiment of the present invention, which is a tube bag, including a bag member  20  and a zipper  22 . The zipper  22  has a circular first section  22   a  on a first side  20   a  of the bag member  20 , and a straight section on a second side of the bag member  20 . The same as above, the first section  22   a  of the zipper  22  may go in any direction other than circular direction. The zippers of above embodiments may provide a big opening to access large goods. 
       FIG. 3  shows a zippered bag  3  of the third preferred embodiment of the present invention, which is a tube bag as well, including a bag member  30  and a zipper  32 . The bag member  30  has a first side  30   a,  a second side  30   b,  and a third side  30   c,  wherein the first side  30   a  is connected to the second side  30   b,  the second side  30   b  is connected to the third side  30   c,  but the first side  30   a  is not connected to the third side  30   c.    
     The zipper  32  extends from the first side  30   a,  through the second side  30   b,  to the third side  30   c.  The zipper  32  has a first section  32   a  on the first side  30   a,  a second section  32   c  on the second side  30   b,  and a third section  32   e  on the third side  30   c.  An end of the first section  32   a  is closer to a joining point  32   b,  which is the point where the first section  32   a  is connected to the second section  32   c,  than a middle portion of the first section  32   a,  and an end  32   f  of the third section  32   e  is closer to a joining point  32   d,  which is the point where the second section  32   c  is connected to the third section  32   e,  than a middle portion of the third section  32   e.  The first section  32   a  and the third section  32   c  go in a circular direction, and the second section  32   c  is straight. 
     When any two or more sections of the zipper  32  are unzipped, it could access large goods through the opening. 
     The zipper  32  is provided with two sliders  321  to unzip the zipper  32  in both directions. For example, in a condition of both of the sliders  321  are at the joining point  32   b  of the first second  32   a  and the second section  32   c,  the opening on the first side  30   a  is opened when the slider  321  is drawn toward the end of the first side  30   a,  and the opening on the second side  30   b  is opened when the other slider  321  is drawn toward the other end of the second side  30   b.    
     It must be pointed out that the embodiments described above are only some preferred embodiments of the present invention. All equivalent structures which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present invention.
