     DETAILED DESCRIPTION 
     In order to obtain a clearer understanding of the technical features, purpose and result of the present application, below is a detailed explanation together with drawings of the preferred embodiment of the present application. 
       FIGS. 1 ,  2  and  6  illustrate a first embodiment of a fluid extrusion bottle of the present application, the embodiment shows a wall-hanging type of fluid extrusion bottle, which is hung on the wall  2  when in use. 
     The embodiment of the fluid extrusion bottle includes a flexible bottle body  1 . When suppressed, the bottle body  1  will undergo flexible deformation. When suppression is released, bottle body  1  will return to original form. Bottle body  1  contains an interior container to store fluids. Please see  FIGS. 3 and 5 . In the embodiment, the bottom section  10  of bottle body  1  contains a fluid exit tunnel  11  that is extended upwardly in a curvature from bottom section  10 . The bottom end of the interior container of the bottle body  1  and the fluid exit tunnel  11  are inter-connected, the top end of the fluid exit tunnel  11  contains a fluid exit mouth  111 . When the fluid extrusion bottle has been hung on the wall, the upper section of the interior container of the bottle body  1  will have a negative pressure, and relies on the curvature design of the fluid exit tunnel  11  to prevent air from entering the bottle body  1 , which can allow the exterior and interior pressure to remain in balance and keep the fluid to maintain inside the interior container of the bottle body  1 . 
     Referring to  FIGS. 2 ,  3  and  5 , in order to prevent any changes in the volume of the fluid  3  and air inside bottle body  1  during changes in temperature and cause leakage in fluids, the embodiment shows that bottle body  1  also contains a temperature elevation storage space  12  that neighbors the fluid exit tunnel  11 . The temperature elevation storage space  12  includes a medium interchangeable tunnel that is connected to the fluid exit tunnel  11 . Medium interchangeable tunnel includes gas changeable tunnel that is located proximal to the fluid exit mouth  111  and fluid changeable tunnel that is located distal from the fluid exit mouth  111 . The medium interchangeable tunnel can be an open mouth on the wall surface of the temperature elevation storage space  12  that neighbors the fluid exit tunnel  111 . At that time, gas changeable tunnel is the region within the open mouth that is proximal to fluid exit mouth  111 . Fluid changeable tunnel is the region within the open mouth that is distal from the fluid exit mouth  111 . In another word, the gas changeable tunnel and the fluid changeable tunnel on the wall surface are inter-connected. When the open mouth is, for example, structured as a slit, a continuous slit would be formed when the gas changeable tunnel and the fluid changeable tunnel combine together. 
     Medium interchangeable tunnel can also includes correspondingly independent gas changeable tunnel and fluid changeable tunnel. Under such design, gas changeable tunnel is a gas hole  122  on the wall surface of the temperature elevation storage space  12  that neighbors the fluid exit tunnel  11 . Fluid changeable tunnel is a fluid hole  121  on the wall surface of the temperature elevation storage space  12  that neighbors the fluid exit tunnel  11 . In another word, gas changeable tunnel and fluid changeable tunnel are correspondingly separated on the wall surface. 
     Referring to  FIGS. 2 ,  3  and  5 , the bottom section of the temperature elevation storage space  12  is higher than or leveling up with the fluid surface  112  inside the fluid exit tunnel  11  when the bottle body  1  has not been pressured. The fluid hole  121  that is connected to the fluid exit tunnel  11  is located at the bottom section of the temperature elevation storage space  12 , the gas hole  122  that is connected to the upper section of the fluid exit tunnel  11  is located at the upper section of the temperature elevation storage space  12 . In preference, the area of the fluid hole  121  and the gas hole  122  can be set to be smaller than the area of the fluid exit mouth  111 . 
     The medium interchangeable tunnel can be round, square and slit etc in shape providing the medium with a structure for entry and exit. For example, when the medium interchangeable tunnel is an open mouth on the wall surface that is connected to the gas changeable tunnel and the fluid changeable tunnel, a slit that is extended towards the fluid exit direction can be designed. When the medium interchangeable tunnel is designed in separating the gas changeable tunnel and the fluid changeable tunnel, fluid hole  121  and gas hole  122  can be individually, for example, a round shaped opening. When the temperature in the environment elevates in bottle body  1  that is in a reserved status, the air and fluid  3  in the interior container of bottle body  1  will expand according to temperature elevation, the fluid surface  112  inside the fluid exit tunnel  11  will progressively elevates. When elevation reaches the level as that of the fluid hole  121  in the temperature elevation storage space  12 , fluid will enter the temperature elevation storage space  12  and air inside the temperature elevation storage space  12  will be released from the gas hole  122 . When temperature is lowered, the air and fluid  3  in the interior of bottle body  1  will contract as temperature is lowered and will create a negative pressure inside the fluid exit tunnel  11 . The fluid inside the temperature elevation storage space  12  will be sucked back into the interior container of the bottle body  1 . Since elevation in temperature is generally slow in normal condition, no large amount of fluid will fill inside the fluid exit tunnel  11  within a short period of time. Fluid can slowly enter and exit the temperature elevation storage space  12 . Similarly, when the medium interchangeable tunnel is structured as a slit that is extended towards fluid exit direction, since the elevation of the fluid surface  112  inside the fluid exit tunnel  11  is slowly progressed in the process of temperature elevation and expansion, fluid enters the temperature elevation storage space  12  through the lower section of the slit, and air inside the temperature elevation storage space  12  can, at this moment, be released to the fluid exit tunnel  11  through the upper section of the slit. 
     As  FIG. 7  illustrates, when the bottle body  1  is suppressed, the volume of the interior container of the bottle body  1  is decreased and the pressure is increased, hence a large amount of fluid is rushed towards the fluid exit tunnel  11 . Since the temperature elevation storage space  12  is a closed space besides having the fluid hole  121  and the gas hole  122 , when fluid passes by fluid hole  121  and gas hole  122 , it may be at a certain level blocked by the air trapped inside the temperature elevation storage space  12  and not be able to enter successfully into the temperature elevation storage space  12 . Hence, large amount of fluids will be discharged from the bottle through the fluid exit mouth  111  of the fluid exit tunnel  11 , while at most only a small amount of fluids enter the temperature elevation storage space  12 . 
     Further, in order to satisfy the work required to be done in the temperature elevation storage space  12  by both the fluid hole  121  and gas hole  122 , the area of the fluid hole  121  and gas hole  122  can be as minimal as possible, preferably, the area of the fluid hole  121  and gas hole  122  should be smaller than the area of the fluid exit mouth  111 , so as to raise the efficiency of fluid extrusion. 
     Setting the fluid hole  121  at the bottom section of the temperature elevation storage space  12 , and the bottom section of the temperature elevation storage space  12  to be at a level higher than or leveling up with the fluid surface inside the fluid exit tunnel  11  when the bottle body  1  has not been pressured, can cause all the fluids to flow back outside the fluid exit tunnel  11  when backwashing, thus prevent wasting. 
     Referring to  FIGS. 1 and 3 , as the embodiment is a wall-hanging type of the fluid extrusion bottle, bottle body  1  includes a backboard  13  that aligns the wall. In order to make it more convenient to situate the fluid extrusion bottle, the upper section of the backboard  13  contains hanging buckles  161  and two-sided adhesive  162 . The two-sided adhesive  162  can be adhered between the wall  2  and hanging buckles  161 , and the bottle body  1  can be installed without the need of supporting and without the need of installing screws through boring holes on the wall, hence making it convenient to use. Obviously, as common understanding, the use of either hanging buckles  161  or two-sided adhesive  162  can also situate bottle body  1 . 
     Referring to  FIGS. 1 ,  4 ,  6 ,  7  and  8 , in order to make the extrusion and deformation of the bottle body  1  easier and extrude in one trial of extrusion sufficient amount of fluid, in the embodiment, the backboard  13  is connected between the left side  14  and the right side  15  through a first flexible deformation section  141  and a second flexible deformation section  151  that are extended towards vertical direction, respectively, the backboard  13  is connected to the top section  19  through a third flexible deformation section  191 . The cross sections of the first, second and third flexible deformation sections  141 ,  151  and  191  are “U” shaped. Further, the first and second flexible deformation sections  141  and  151  are progressively widened from top to bottom. Since the cross sections of the first, second and third flexible deformation sections  141 ,  151  and  191  are “U” shaped, extrusion is easier. The change in volume of the bottle body  1  is relatively large, bottle body  1  can more easily return to its original form after suppression. In the present embodiment, the fluid exit tunnel  11  is located at the center of the bottom section  10 . The first and second flexible deformation sections  141  and  151  are extended downward from the upper section of bottle body  1 . The design of the “U” shaped cross sections of the first and second flexible deformation sections  141  and  151  enables extrusion to become easier and the bottle can return to its original form more easily. In view of the previous design (Chinese Design Patent No. CN2839130Y), the force (F 2 ) produced against the hanging buckles under the force (F) of the bottle and the reaction force of the wall is relatively small, or even F 2  may not be produced so as to prevent the two-sided adhesive  162  from being torn off from the wall due to excessive force F 2 . 
     Referring to  FIGS. 1 and 9 , furthermore, in order to prevent large amount of fluid from spilling out due to accidental collapsing of the bottle, in the present embodiment, fluid exit tunnel  11  is preferably initially upwardly curved and then forwardly curved in shape, while the end surface of the fluid exit mouth  111  of the fluid exit tunnel and uppermost front side  17  of bottle body  1  belong to the same plane. That way, even if bottle body  1  accidentally collapsed as shown in  FIG. 9 , since the fluid exit mouth  111  is lying flat on the ground, the gap between the fluid exit mouth and the ground is sealed after small amount of fluid is spilled out, rendering air unable to enter the bottle body  1  and fluid inside the interior container of the bottle body  1  will not leak outside. When the fluid exit mouth  111  is in an upward position, the fluid inside the interior container of bottle body  1  will not leak from the fluid exit tunnel  11 . 
     As  FIGS. 10 and 13  illustrate, as a second embodiment of the fluid extrusion bottle of the present application, the embodiment shows a fluid extrusion bottle as a vertical standing fluid extrusion bottle. The vertical standing fluid extrusion bottle includes a flexible bottle body  1 , the bottle body  1  has an interior container for storing fluid, the bottle body  1  can flexibly deform when being externally pressured. In order to allow the bottle body  1  to stand vertically on the platform, the bottom section of bottle body  1  contains a supporting base  18  for allowing the bottle body  1  to stand above the horizontal surface level, the bottom of the supporting base  18  can stand on the platform. 
     Referring to  FIGS. 11 ,  12  and  13 , in the present embodiment, the bottom  10  of bottle body  1  includes a fluid exit tunnel  11  that is extended from the bottom  10  and upwardly curved. The bottom end of the fluid exit tunnel  11  and the interior container of the bottle body  1  are connected, the upper end of the fluid exit tunnel  11  contains a fluid exit mouth  111 , bottle body  1  also includes a temperature elevation storage space  12  that neighbors the fluid exit tunnel  11 . The bottom of the temperature elevation storage space  12  is higher than or in leveling with the fluid surface inside the fluid exit tunnel  11  when the bottle has not been pressured. The bottom of the temperature elevation storage space  12  contains fluid hole  121  that is connected to the fluid exit tunnel  11 . The upper section of the temperature elevation storage space  12  contains gas hole  122  that is connected to the upper section of the fluid exit tunnel  11 . In the present embodiment, the working principle of the temperature elevation storage space  12  is the same as that of the temperature elevation storage space of the wall hanging type fluid extrusion bottle in the first embodiment, and hence will not be reiterated. 
     Referring to  FIGS. 13 ,  14  and  15 , in order to prevent the fluid inside the bottle body  1  from leaking when the bottle body  1  collapses, in the present embodiment, furthermore, the fluid exit tunnel  11  of bottle body  1  is preferably extended from the bottom  10  initially upwardly at an angled direction and then extended at a horizontal surface level direction. That way, no matter whether the bottle body  1  is falling backward, as shown in  FIG. 14 , or is falling forward, as shown in  FIG. 15 , the curvature of the fluid exit tunnel  11  can always prevent the fluid from leakage outside of the bottle body  1 . 
     In the fluid extrusion bottle of the present application, the temperature elevation storage space and the fluid exit tunnel are correspondingly independent, both can be limitedly connected through a medium interchangeable tunnel, which can raise the fluid extrusion efficiency of the fluid extrusion bottle and reduce waste. The structure of the bottle of the fluid extrusion bottle of the present application is simple, which can be produced from only one material such as by plastic molding, and is low in production costs and convenient for recycling, thus more environmental friendly. Further, for the wall hanging type fluid extrusion bottle, the operation is very convenient as a single hand can complete the action of fluid extrusion, hence providing convenience to the user. 
     The aforementioned together with the drawings have described the embodiments of the present application. However, the present application is not confined to the above general embodiments. The above-mentioned general embodiment is merely illustrative instead of limitative in nature. Common technicians in the field can also perform many other forms under the disclosure of the present application without departing from the objectives of the present application and the protective scope as recited in the claims, which are all belonging within the protective scope of the present application.
