     BACKGROUND OF THE INVENTION 
       [0002]    The present invention relates to a foam jetting tube container, and the foam jetting tube container enables contents stored inside of a container body to be moved through a content moving tube when the container body is pressurized, and then allows the contents to be mixed with air flowing through an air inflow hole in a mixing part inside of a housing so as to primarily form foam, and allows foam to be secondarily formed when the foam passes through a foam mesh positioned above the mixing part so as to discharge foam to the outside, thereby jetting foam through a simple structure. 
         [0003]    Generally, a foam jetting tube container refers to a container having a structure wherein a user pressurizes a container body having contents stored and makes the container form foam in the process of discharging the contents by mixing with outside air. 
         [0004]    A foam jetting tube container as the above is disclosed in the Korean Registered Patent No. 10-1067748 (hereafter called as ‘the registered patent’). 
         [0005]    The registered patent, which the present applicant filed on Oct. 9, 2009 and was registered as such, comprises a first container body containing contents; an inner container combined to an upper portion of the first container body and comprising a first tube neck to which a hollow is formed so as for the contents to be discharged; an outer container, which is combined to the inner container as encasing, comprising a second tube neck combined at an upper portion thereof, separated from the inner container with a constant distance and forming a space, which forms a multitude of first air holes separated with a constant distance; an inner cap which is combined to an upper portion of the outer container, comprising a multitude of second air holes separated with constant distance at an upper end thereof; a support cap which is combined to the inner cap at a lower portion of the second tube neck, comprising a protrusion wherein a multitude of third air holes are formed with a constant distance separated at a side thereof; a check valve combined to a lower portion of the support cap directly above the hollow and preventing reflux of content; an air valve which is combined, encasing a lower end of the second air holes and an inner circumferential surface of the support cap in an interior of the inner cap and, made of elastic material, opens/closes either the second air hole or a third air hole according to movement of air; and an outer cap which is combined, encasing the inner cap, comprising a foam mesh at an end of the center thereof. 
         [0006]    However, the registered application has some problems in that the container should be equipped with double tubes in order to make a space where air flows in and is kept, and also has a complicated structure for air inflow, such that it needs a substantial manufacturing time, which thereby results in increasing users&#39; burden. 
       SUMMARY OF THE INVENTION 
       [0007]    The present invention was devised to solve these problems in the above, and its goal is to provide a foam jetting tube container which enables contents stored inside a container body to be moved through a content moving tube when the container body is pressurized, and then allows the contents to be mixed with air flowing through an air inflow hole in a mixing part inside of a housing so as to primarily form foam, and allows the foam to be secondarily formed when the foam passes through a foam mesh positioned above the mixing part so as to discharge foam to the outside, thereby jet ting foam through a simple structure. 
         [0008]    To solve the above problems, a foam jetting tube container according to the present invention comprises a container body where contents are contained and which is transformed by user&#39;s pressurization, thereby discharging contents through the discharge hole; a housing, which is combined to the discharge hole and closes an upper end of the discharge hole at a center portion thereof, comprising a mixing part which primarily generates foam as contents stored in the container body is mixing with air; a foam mesh which is combined to an upper portion of the mixing part and secondly generates foam; an outer cap which encases the housing and the foam mesh and is combined to the discharge hole, comprising a foam jetting hole such that the foam formed through the housing and the foam mesh is jetted out. 
         [0009]    Furthermore, it is characterized that at a lower end of the mixing part is equipped a content inflow hole which the contents stored in the container body flows in, and at a side surface of the mixing part is equipped an air inflow hole which air existing in the interior of the container body flows in. 
         [0010]    Furthermore, it is characterized that at the housing is equipped an air inlet such that outside air can come in, and at the air inlet is equipped a valve member which regulates incoming of outside air according to the pressurization of the container body. 
         [0011]    Furthermore, it is characterized that at a lower end of the mixing part is equipped a content moving tube which moves the contents stored in the container body to direction of the mixing part. 
         [0012]    Furthermore, it is characterized that the air inflow hole has a function of a passage where the contents stored in the container body moves when the container body is pressurized in a state of the container body upside down, and the content moving tube has a function of a passage where the air stored in the container body moves. 
         [0013]    As described as the above, the present invention has an advantage wherein contents stored inside of a container body move through a content moving tube when the container body is pressurized, and then allows the contents to be mixed with air flowing through an air inflow hole in a mixing part inside of a housing so as to primarily form foam, and allows the foam to be secondarily formed when the foam passes through a foam mesh positioned above the mixing part so as to discharge foam to the outside, thereby jetting foam through a simple structure.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0018]    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members. 
         [0019]      FIG. 1  is an exploded cross-sectional view illustrating a configuration of a foam jetting tube container according to an exemplary embodiment of the present invention, and  FIG. 2  is a cross-sectional view illustrating a configuration of a foam jetting tube container according to an exemplary embodiment of the present invention; 
         [0020]    Referring to  FIGS. 1 and 2 , a foam jetting tube container according to an exemplary embodiment of the present invention includes a container body  100 , a housing  200 , a foam mesh  300 , and an over cap  400 . 
         [0021]    The container body  100 , where liquid-type contents are stored, comprises a discharge hole at an upper portion thereof such that the contents can be discharged by a user&#39;s pressurizing. 
         [0022]    The container body  100  can be composed of a tube container or a blow container which is able to be modified by a user&#39;s pressurizing and discharges the contents stored in the container body. 
         [0023]    The housing is combined to the discharge hole  110  at an upper portion of the container body  100  and closes an upper end of the discharge hole  110 , the housing in the present invention is characterized in that at the center portion of the housing  200  is equipped a mixing part  210  where the contents and the air stored in the container body  100  are mixed and foam is primarily formed. 
         [0024]    The mixing part  210 , so as to make the contents and the air mixed, is equipped with a content inflow hole  211  at a lower end thereof, which the contents stored in the container body  100  flows in, and at a side surface thereof is equipped with an air inflow hole  212  where the air stored in the interior of the container body  100  enters, and at a lower end of the mixing part  210  is equipped a content moving tube  230  such that the contents stored in the container body  100  moves to direction of the mixing part  210  and flows into the mixing part  210  through the content inflow hole  211 . 
         [0025]    Meanwhile, the housing  200  is featured to include an air inlet  220  thereof such that outside air enters the container body  100 , wherein at the air inlet  220  is installed a valve member  221  which regulates entering of outside air according to whether the container body  100  is pressurized or not. 
         [0026]    The valve member  221  ascends or descends inside the air inlet  220  according to the operation of pressurizing the container body  100  or releasing the pressure, thereby closing an upper portion or a lower portion of the air inlet  220 . When pressure of the container body  100  is released and thereby the valve member  221  moves from an upper portion to a lower portion of the air inlet  220 , air enters an interior of the container body  100  through a space separated between an inner wall of the air inlet  220  and the valve member  221 . 
         [0027]    The foam mesh  300  is combined to an upper portion of the mixing part  210  and generates foam, wherein the content and air stored in the container body  100 , in a process of moving upward, go through the mixing part  210 , primarily forming foam, and then pass through the foam mesh, secondly forming foam. When enough foam is formed, the foam is discharged to the outside through the foam getting hole  411 . 
         [0028]    The over cap  400  encases the housing  200  and the foam mesh and is combined to the discharge hole  110 , comprising a cap body  410  which has a screw thread at an inner circumferential surface and is combined in screw coupling to the discharge hole  110 , comprising a foam jetting hole  411  at the center of a cap body  410  such that discharging foam is possible, and a cover  420  which is combined in a hinge combination with one side of the cap body  410  and opens/closes the foam jetting hole  411 . It is preferable that at an inner side of the cover  420  is equipped a closing protrusion  421  which opens/closes the foam jetting hole  411  and thereby prevents contents from being leaked. 
         [0029]    Meanwhile, at an upper end of the housing  200  is combined a fixing cap  500  which supports the foam mesh  300 , wherein a hollow  510  is formed at the fixing cap  500  such that foam, formed while going through the foam mesh  300 , can move. 
         [0030]    Hereinafter, the foam jetting process of a foam jetting tube container according to an exemplary embodiment of the present invention will be described with reference to  FIGS. 3 and 4 .  FIGS. 3 and 4  are constitutional views illustrating an operational state of a foam jetting tube container according to an exemplary embodiment of the present invention. 
         [0031]    First, referring to  FIG. 3 , a foam jetting tube container according to an exemplary embodiment of the present invention, when a user pressurizes a container body  100  with the container body  100  in an upright position, the contents stored in the container body  100  moves to an upper portion thereof through a content moving tube  230  and flows into a mixing part  210  through a content inflow hole  211 , and at the same time, the air contained in an upper portion of the container body  100  flows into the mixing part  210  through an air inflow hole  212 , such that the contents and the air are mixed in the mixing part  210 , primarily forming foam, and then secondly forms foam as going through a foam mesh  300  positioned at an upper portion of the mixing part  210 , then being discharged to the outside through a foam jetting hole  411 . At this time, a valve member  221  moves to an upper portion of the air inlet  220  by internal pressure of the container body  100 , thereby closing the air inlet  220 . 
         [0032]    As above, when pressurization of the container body  100  is released in a state of foam jetting completed, the internal pressure of the container body  100  is released, and thereby, shown in  FIG. 5 , the valve member  221  which moved up to an upper portion of the container  220  comes to descend. During this process when the valve member is descending, air from the outside enters into the interior of the container body  100  through a separated space formed between an inner wall of the air inlet  220  and the valve member  221 , and thereby the air is stored in an inner upper space of the container body  100 , and when the user pressurizes the container body  100  again, the air contained in the inner upper space of the container body  100  flows in through the air inflow hole  212  and mixes with contents in the mixing part  210 , then jetting foam. 
         [0033]    Meanwhile, shown in  FIG. 4 , when the container body  100  is pressurized in a state of the container body  100  being upside down, the air inflow hole  212  functions as a passage where the contents stored in the container body  100  moves whereas a content moving tube  230  functions as a passage where air stored in the container body  100  moves. Therefore, contents flow in through the air inflow hole  212  while air flows in through the content moving hole  230 , and then contents and air are mixed in the mixing part  210 , such that it is possible for foam to be jetted easily even in a state of the container body  100  being upside down. 
         [0034]    The process that contents and air are mixed through the mixing part  210  and a foam mesh and then foam is jetted is the same as the above; therefore, detailed descriptions are omitted. 
         [0035]    As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been used herein, these are only intended to describe the present invention and are not intended to limit the meanings of the terms or to restrict the scope of the present invention as disclosed in the accompanying claims. Therefore, those skilled in the art will appreciate that various modifications and other equivalent embodiments are possible from the above embodiments.
