     DETAILED DESCRIPTION OF THE INVENTION 
       [0022]    The preferred embodiments of the present invention will be described with reference to the accompanying drawings. It is noted that throughout the specification, the same reference numerals mean same elements. 
         [0023]      FIG. 1  is a disassembled cross sectional view illustrating a construction of the contents refillable paper tube container according to a preferred embodiment of the present invention.  FIG. 2  is an engaged cross sectional view illustrating a construction of the contents refillable paper tube container according to a preferred embodiment of the present invention.  FIG. 3  is a view for explaining a use state of the contents refillable paper tube container according to a preferred embodiment of the present invention. 
         [0024]    As sown in  FIGS. 1 to 3 , the contents refillable paper tube container according to a preferred embodiment of the present invention comprises a paper tube body  100 , a pumping member  200 , a pouch part  300  and a paper tube cap  400 . 
         [0025]    The paper tube body  100  is equipped with a space in which to store contents and is formed of a paper tube part  110  forming a side surface and a support part  120  which is formed at the bottom of the paper tube part  110  for thereby opening and closing the bottom. 
         [0026]    The present invention has features in that the paper tube body  100  is made from a paper material. The pumping member  200  is interference fitted with a user&#39;s pressurization, so the work for manufacturing an engaging member which is used for an engagement between members of a container can be omitted in the middle of the manufacture of the cosmetic container for thereby reducing manufacture time and costs. 
         [0027]    Since the paper tube body  100  is made from a paper material, a character, an image and a symbol can marked on its outer surface or a post-process for providing various colors can be easily performed, for thereby reducing defective products. 
         [0028]    Since the paper tube body  100  is made from a paper material, the paper tube body can be recycled, thus preventing environment destruction. 
         [0029]    The pumping member  20  is engaged, covering the top of the paper tube body  100 , for thereby discharging to the outside the contents stored in the pouch part  300  through the pumping operations. It is preferred that an engaging groove  210  is formed at a portion contacting with the top of the paper tube body  100  and is engaged to the paper tube body  100 . 
         [0030]    In the present invention, the pumping member  200  is detachable from the paper pipe body  100 . The pumping member of the cosmetic container is reliably fixed by way of a fixing member like a support cap fixing the pumping member; however the pumping member  200  of the present invention can be detachable from the paper tube body  100  by a user&#39;s pressurization for the pouch part  300  to be easily exchanged if necessary. 
         [0031]    In the present invention, at the bottom of the pumping member  200  is provided an engaging part  220  with a thread  221  which is engaged with the fixing part  320  of the pouch part  300 . 
         [0032]    The pumping member  200  is thread-engaged to the fixing part  320  of the pouch part  300  through the engaging part  220 , so when the user disengages the pumping member  200  from the paper tube body  100 , the pouch part  300  disengages together. The pouch part  300  can be exchanged as the thread engagement between the engaging part  220  and the fixing part  320  is disengaged. 
         [0033]    When the exchange of the pouch part  300  is finished, the user holds the pumping member  200  and engages it to the paper tube body  100 . At this time, while the pumping member  200  is slowly engaged to the paper tube body  100 , the engaging groove  210  of the pumping member  200  is mounted on the top of the paper tube body  100  and is engaged to the paper tube body  100 . 
         [0034]    Since the constructions applied to the pumping operations of the pumping member  200  are known in the art, the descriptions thereof will be omitted. 
         [0035]    The pouch part  300  stores contents and is detachably engaged to the engaging part  220  for the sake of its exchange when the contents are all consumed and comprises a pouch  310  for storing contents, a fixing part  320  which supports the pouch  310  and has an opening  321  at its center for filling or discharging the contents and threads  322  at its outer surface for a thread engagement to the engaging part  220 , and a pressurization part  330  which is engaged to the opening  321  at the top of the fixing part  320  and has a hollow portion  331  for filling or discharging the contents. 
         [0036]    In the present invention, the top of the pouch  310  comes into close contact with the inner surface of the fixing part  320 , the end portion of which being mounted on the top of the fixing part  320  and being fixed by means of the pressurization of the pressurization part  330 . For the sake of the reliable fixing of the pouch  310 , a fixing shoulder  323  is formed at the top of the fixing part  320  in order to prevent the pouch  310  from being disengaged. A pressurization protrusion  332  is formed at the pressurization part  330  for pressurizing and fixing the pouch  310 . 
         [0037]    The pouch  310  is fixedly supported by the fixing part  320  with the aid of the pressurization of the pressurization part  330 , so the pouch  310  can be prevented from being disengaged from the fixing part  320  when fixing the contents into the pouch  310 . 
         [0038]    The pressurization part  330  is so positioned that the pouch  310  is not exposed to the outside in such a way to pressurize the top of the pouch  310 . Consequently, the pouch  310  can be prevented from being damaged for it is distorted by rotations when thread-engaging the pouch part  300  to the engaging part  220 . 
         [0039]    The paper tube cap  400  is engaged to the top of the paper tube body  100  and covers the pumping member  200  for thereby protecting the pumping member  200  from external impacts, which results in preventing erroneous operations of the pumping member  200 . 
         [0040]    In the present invention, the paper tube cap  400  is made from a paper material. Since the paper tube cap  400  is made from a paper material, it can be recycled when its lifespan is over for thereby preventing environment destruction. 
         [0041]    The exchanges of the pouch of the contents refillable paper tube contain according to the preferred embodiments of the present invention will be described with reference to  FIGS. 1 to 3 . 
         [0042]    As best seen in  FIGS. 1 to 3 , when the contents are all consumed, the user holds the pumping member  200  and lifts it up and disengages from the paper tube body  100 . At this time, the pouch part  300  engaged to the engaging part  220  of the pumping member  200  is disengaged together. 
         [0043]    When the pumping member  200  moves upward, and the pouch part  300  is disengaged from the paper tube body  100 , the user rotates the fixing part  320  of the pouch part  300  in one direction for thereby disengaging the pouch part  300  from the engaging part  220 , and the pouch part  300  full of new contents is engaged to the engaging part  220  for thereby finishing the exchange of the pouch part  300 . 
         [0044]    When the exchange of the pouch part  300  is finished, the pumping member  200  is engaged to the paper tube body  100 . When the pumping member  200  is pressurized from the top of the paper tube body  100  to the lower side, the engaging groove  210  of the pumping member  200  is slowly engaged to the paper tube body  100  and is mounted on the top of the paper tube body  100 , so it is interference-fitted into the paper tube body  100 . At this time, the paper tube body  100  should be thick enough to prevent any transformation when the paper tube body  100  is interference-fitted into the pumping member  200  because it may be transformed thanks to a flexible paper material. 
         [0045]    As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
