BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates generally a portable water bag, and more particularly to a flexible tube of the water bag. 
         [0003]    2. Description of the Related Art 
         [0004]    Portable water bags are the common equipments of jogging, mountain-climbing, bicycle riding and so on. Typically, the conventional portable water bag includes a soft bag to be received in a backpack or in a specific pack. The bag has an intake to pour water into the bag, a lid to close the intake, a hose with an end connected to the bag, mouthpiece connected to a free end of the hose. People may suck the mouthpiece to drink water or just pour water on head or body to get cool. The hose has a part received in the backpack and the rest part exposed. User may hold the mouthpiece and put it in mouth to drink water. When user releases the mouthpiece, it will hang down on the backpack. If user is riding a bike, he/she has problem to reach the hung mouthpiece. 
       SUMMARY OF THE INVENTION 
       [0005]    The primary objective of the present invention is to provide a water bag with a mouthpiece that is easy to reach. 
         [0006]    According to the objective of the present invention, a water bag includes a soft bag with an intake, a lid detachably covering the intake of the bag, a hose having en end connected to the bag and a mouthpiece connected to a free end of the hose. The present invention further provides a plastic deformation tube between the hose and the mouthpiece, which may be bent freely and fix the mouthpiece at a position after bending. Therefore, user may bend the plastic deformation tube to have the mouthpiece at a suitable position for drinking without having to hold the mouthpiece by hand. 
         [0007]    Another character of the present invention is the water inlet of the present invention fits to a common mineral water bottle, such that user only needs to engage the mineral water bottle with the water inlet, and water in the water bottle will flow to the soft bag.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0018]    As shown in  FIG. 1 , a water bag of the preferred embodiment of the present invention includes: 
         [0019]    A soft bag  10  has an intake  11  to inject water. 
         [0020]    A lid  12  covers the intake  11  to close or open the intake  11 . 
         [0021]    A hose  15  has an end connected to the bag  10 . The bag  10  has three rings  13  on a side for the hose  15  passing through. 
         [0022]    A mouthpiece  20  is connected to a free end of the hose  15 . 
         [0023]    A plastic deformation tube  40  -has opposite ends connected to the hose  15  and the mouthpiece  20 , which may be bent and fixed at that shape to adjust a position of the mouthpiece  20 . 
         [0024]    The plastic deformation tube  40  includes a main tube  41 , a sub-tube  42  attached on a circumference of the main tube  41 , and a metal bar  43  in the sub-tube  42 . The metal bar  43  may be bent and fixed at that shape. With the plastic deformation tube  40 , user may adjust the mouthpiece  20  at desired positions, such that user may drink water by moving his/her mouth toward the mouthpiece  20 . And when user releases the mouthpiece  20 , the plastic deformation tube  40  will keep the mouthpiece  20  still that facilitates user to drink water again. With the plastic deformation tube  40  of the present invention, user doesn&#39;t have to hold the mouthpiece  20  by hand, so that he/she may drink water with both hands free for bike riding, jogging, climbing mountain or other exercises or jobs. 
         [0025]    In addition, for convenience of filling water, a three-way valve  30  is mounted between the plastic deformation tube  40  and the hose  15 . The three-way valve  30  has a first end connected to the hose  15 , a second end connected to the plastic deformation tube  40  and a third end forming a water inlet  31 . On an interior wall of the water inlet  31  of the connector three-way  30 , a threaded section  32  is provided. The water inlet  31  may be engaged with a common mineral water bottle, as shown in  FIG. 7 . A cap  35  has a threaded section  36  to be screwed to a threaded section  32  of the water inlet  31 . The cap  35  is provided with a strip  37  and a ring  38  on an end of the strip  37 . The ring  38  is fitted to an annular slot  33  on the three-way valve  30  adjacent to the water inlet  31 , such that the cover will not loose when the cap  35  is opened. A leakage-proof ring  34  is provided in the cap  35  to press the three-way valve  30  when the cap  35  is screwed onto the three-way valve  30  for leakage-proof. 
         [0026]    When water in the bag  10  is out, user may open the cap  35  and screw an opening  91  of a common water bottle  90  into the water inlet  31 , as shown in  FIG. 7 , to inject water into the bag  10  through the hose  15 . After filling, user only needs to close the cap  35  that is a very convenient operation. 
         [0027]    The water bag of the present invention is further provided with a switch  50  between the plastic deformation tube  40 . The switch  50  includes two members  51 ,  55 , in which the first member  51  is connected to the plastic deformation tube  40  and the second member  55  is connected to the mouthpiece  20 . The members  51 ,  55  are connected together and may be rotated relative to each other. The second member  55  as a tunnel  56 , and the first member  51  has a plug  52 . When the members  51 ,  55  are turned, the first member  51  may be moved away from the second member  55 , as shown in  FIG. 4 , in which water may flow through the switch  50 . The members  51 ,  55  also may be turned in opposite direction to have the first member  51  moved toward the second member  55 , as shown in  FIG. 5 , in which the plug  52  seals the tunnel  56  to cut off water. 
         [0028]    The mouthpiece  20  includes a flexible body, in which a tunnel  21  is provided, with a closed end. On the closed end of the tunnel  21 , an elongated crack  22  is provided, as shown in  FIG. 8 . The crack  22  is closed in a normal condition, such that water will not flow out, and it is opened when the flexible body is compressed along an elongated direction of the crack  22 , such that water may flow out. A cap  25  covers the closed end of the mouthpiece  20  with a strip  26  and a ring  27 . The ring  27  is fitted to a slot  23  on a circumference of the mouthpiece  20 , such that the cap  25  will not loose. The main purpose of the cap  25  is dustproof, except that the cap  25  compresses the mouthpiece  20  to seal the crack  22  for leakage-proof when the cap  25  is covered on the mouthpiece  20 . The ring  27  may restrict the flexible body to ensure the crack  22  closed. 
         [0029]    As shown in  FIG. 9 , the tunnel  21  has a quadrilateral section  24 , such as rhombus, square or rectangle, adjacent to the closed end. The crack  22  extends along a diagonal line of the quadrilateral section  24 . The present embodiment shows the crack  22  extends along a short diagonal line of the rhomboidal section  24  that benefits the crack  22  to keep closed. 
         [0030]    As shown in  FIG. 10 , the present invention further provides a lock device  60 , which is an elongated plate with a C-shaped clip  61  on a center thereof and two connectors  62  on opposite sides of the clip  61 . The clip  61  may hold the plastic deformation tube  40  or the hose  15 . The connectors  62  may connect an O-ring  63  (or elastic band). The O-ring  63  is wound on a back of a belt of a backpack and engages opposite ends thereof with the connectors  62  to mount the lock device  60  on the backpack, such that the plastic deformation tube  40  may be fixed on the lock device  60 . User may bend the plastic deformation tube  40  to have the mouthpiece  20  at a suitable position for drinking. 
         [0031]    The description above is a few preferred embodiments of the present invention and the equivalence of the present invention is still in the scope of the claim of the present invention.
