Title: Receptacle for mixing of different materials

Description:
TECHNICAL FIELD 
     The present invention relates to a receptacle for mixing different materials, and more particularly, to a receptacle for mixing different materials, in which an inner receptacle is inserted into an outer receptacle, and one of pump sets is mounted on the inner receptacle, thereby storing cosmetic contents different from each other in the inner receptacle and the outer receptacle, and using them simultaneously by one pumping. 
     BACKGROUND ART 
     When mixing two materials of different ingredients (cosmetics, etc.) in advance, a problem that these materials deteriorate due to chemical reaction in the mixed state or the performance is remarkably degraded may occur. If the user uses the materials by mixture after preparing and storing two containers, respectively, there arises a problem caused by the inconvenience in use. 
     In order to solve these problems, a receptacle for mixing different materials having a configuration capable of mixing two materials by the operation of the user after separating and storing two materials in one receptacle is devised and used. 
       FIGS. 4 and 5  are cross-sectional views of a conventional container of mixing different materials. 
     The conventional container for mixing different materials, as shown in these drawings, includes: a container body portion  111 , in which a container storage space  111   a  is formed and a container opening  111   b  is formed at an upper end thereof; s shoulder portion  113  coupled to an upper end of the container body portion  111 ; an inner cap  112  formed integrally with the shoulder portion  113 ; a container cap  118  coupled to the shoulder portion  113 ; a push button  114  disposed on the upper side of the inner cap  112 ; a pressure tube  119  coupled to the bottom surface of the push button  114 ; a cylinder  150  installed to communicate with the container storage space  111   a ; a pumping portion  140  interposed between the cylinder  150  and the push button  114 ; and a secondary storage space portion  160  provided with an auxiliary storage space body portion  161  coupled to the cylinder  150 . 
     The inner cap  112  is formed with a cap hole  112   a  in a central region thereof. 
     The inner cap  112  having such a configuration is coupled to the shoulder portion  113  so that the cap hole  112   a  communicates with the container storage space  11   a.    
     The push button  114  is formed with a “¬”-shaped button flow path  114   a  which connects the bottom surface and the side surface. The push button  114  can move along the height direction of the container body portion  111 . 
     The pressure tube  119  is formed so as to communicate with the button flow path  114   a  and the cap hole  112   a.    
     The cylinder  150  is formed with a narrowed portion  151  on a bottom region thereof. 
     The narrowed portion  151  is formed with a through hole  151   a  on the bottom surface thereof and a cylinder engaging shoulder  151   b  is formed on the inner surface thereof. The pumping portion  140  includes: a ring-shaped pumping piston  141  installed in the cylinder  150 ; an operating shaft  145  installed to enter into the pressure tube  119  through the pumping piston  141 ; an operating rod  146  installed in the operating shaft  145 ; an opening and closing recessed groove portion  147  formed at the lower end of the operating rod  146 ; a straw support tube  148  installed so that the upper end thereof reaches the bottom surface of the opening and closing recessed groove portion  147  and the lower end thereof passes through the through hole  151   a  to be exposed to the outside of the cylinder  150 ; a straw  149  installed inside the straw support tube  148 ; and a return spring  144  installed to support both ends thereof by the push button  114  and the inner cap  112 . 
     The pumping piston  141  is installed to be in close contact with the inner surface of the cylinder  150  such that an intermediate storage chamber  150   a  is formed between the bottom surfaces of the cylinder  150 . 
     In addition, the pumping piston  141  is installed in the cylinder  150  to be spaced apart from the lower end of the pressure tube  119 . 
     Accordingly, when lowering the pressure tube  119  by pressurizing the push button  114 , the pumping piston  141  is lowering alone by the distance that the pressure tube  119  is spaced apart from the pumping piston  141 , and then can be lowered together with the pressure tube  119 . 
     The operating shaft  145  includes a linear operating shaft body portion  145   b  and a stem  145   c  formed at the lower end of the operating shaft body portion  145   b.    
     The inner space of the operating shaft body portion  145   b  becomes the operating shaft flow path  145   a.    
     The stem  145   c  pressurizes the pumping piston  141  upward during a lifting operation. 
     The operating shaft  145  having such a configuration is installed such that the stem  145   c  passes through the pumping piston  141  and the operating shaft body portion  145   b  is coupled to the pressure tube  119 . In this way, the operating shaft  145  can move up and down together with the pressure tube  119 . 
     The opening and closing recessed groove portion  147  is formed with a plurality of opening and closing recessed groove flow path forming protrusions  147   a  protruding along the longitudinal direction on the upper side of the outer surface thereof. 
     The opening and closing recessed groove flow path forming protrusions  147   a  are spaced apart from each other, and thus the opening and closing recessed groove flow path is formed in a space between the opening and closing recessed groove flow path forming protrusions  147   a.    
     The straw support tube  148  is formed with a plurality of support tube flow path forming protrusions  148   a  protruding along the longitudinal direction on the upper side of the outer surface thereof. 
     The support tube flow path forming protrusions  148   a  are spaced apart from each other, and thus a support tube flow path is formed in a space between the support tube flow path forming protrusions  148   a . The return spring  144  is installed so that both ends thereof are supported by the push button  114  and the inner cap  112 . 
     The auxiliary storage space portion  160  is provided with an auxiliary storage space sealing plate portion  162  formed at the lower end of the straw support tube  148  in addition to the auxiliary storage space body portion  161 . 
     The auxiliary storage space sealing plate portion  162  is formed to be disposed perpendicularly to the longitudinal direction of the straw support tube  148 . 
     The auxiliary storage space body portion  161  has a configuration capable of forming a closed space in cooperation with the straw supporting tube  148 , the auxiliary storage space sealing plate portion  162 , and the cylinder  150 . 
     The operation of a conventional container for mixing different materials having such a configuration will be described herein with reference to  FIGS. 6 and 7 . For convenience of explanation, it is assumed that the liquid cosmetics are stored in the inner space of the container body portion  111 , that is, the container storage space  111   a , and the powdered cosmetics are stored in the auxiliary storage space portion  160 . 
     When first pressurizing the push button  114  downward, the pressure tube  119  is lowering alone by a distance spaced apart from the pumping piston  141 , and then the pressure tube  119  is lowering together with the pumping piston  141 . When the push button  114  is pressurized, an elastic force is accumulated in the return spring  144 . 
     When the pressure tube  119  is lowering, the opening and closing recessed groove portion  147  and the straw support tube  148  are also lowered. Here, the lowering of the opening and closing recessed groove portion  147  is achieved such that the opening and closing recessed groove flow path forming protrusions  147   a  cross the cylinder engaging shoulder  151   b.    
     When the straw support tube  148  is lowering, the auxiliary storage space sealing plate portion  162  is also lowered so as to cross the lower end of the auxiliary storage space body portion  161 . 
     When the auxiliary storage space sealing plate portion  162  is lowering, powdered cosmetics stored in the auxiliary storage space portion  160  and liquid cosmetics stored in the container storage space  111   a  are mixed (see  FIG. 7 ). 
     Next, when the pressure applied to the push button  114  is releasing, the push button  114  lifts to the original position by elastic force accumulated in the return spring  144 . When the push button  114  is lifted, the operating shaft  145  and the pumping piston  141  are lifted and the operating shaft flow path  145   a  is closed by the pumping piston  141 . 
     When the operating shaft  145  is lifted, the operating rod  146  and the opening and closing recessed groove portion  147  are also lifted. Here, the lifting distance between the operating rod  146  and the opening and closing recessed groove portion  147  is limited by the engagement action between the opening and closing recessed groove flow path forming portion  147   a  and the cylinder engaging shoulder  151   b.    
     When the operating rod  146  and the opening and closing recessed groove portion  147  are lifted, the groove bottom surface of the opening and closing recessed groove portion  147  and the upper end of the straw  149  are spaced apart from each other, and thus the container storage space  111   a  is connected to the intermediate storage chamber  150   a  through the opening and closing recessed groove flow path, which is formed in a space between the straw  149  and the opening and closing recessed groove flow path forming protrusion portions  147   a , and the support tube flow path, which is formed in a space between the straw  149  and the support tube flow path forming protrusions  148   a.    
     In this way, when the container storage space  111   a  is connected to the intermediate storage chamber  150   a , the operating shaft  145  is lifted to generate a negative pressure in the intermediate storage chamber  150   a , and the mixed cosmetics in the container storage space  111   a  flow into the intermediate storage chamber  150   a  through the support tube flow path (see  FIG. 8 ). 
     Next, when the push button  114  is pressed downward, the pressure tube  119  is lowering alone by a distance spaced apart from the pumping piston  141 , and then the pressure tube  119  is lowering together with the pumping piston  141 . 
     The operating shaft flow path  145   a  communicates with the intermediate storage chamber  150   a  while the pressure tube  119  is lowering alone by the distance spaced apart from the pumping piston  141 . 
     When the operating shaft flow path  145   a  communicates with the intermediate storage chamber  150   a , the mixed cosmetics in the intermediate storage chamber  150   a  sequentially pass through the operating shaft flow path  145   a , the pressure tube  119 , and the button flow path  114   a  to be discharged to the outside. 
     On the other hand, when the push button  114  is lowering, the return spring  144  accumulates elastic force. 
     Next, when the pressing force to the push button  114  is released, the push button  114  is lifted to the original position by the elastic force accumulated in the return spring  144 . 
     When the push button  114  is raised, the operating shaft  145  and the pumping piston  141  are lifted, and the operating shaft flow path  145   a  is closed by the pumping piston  141 . 
     When the operating shaft  145  is lifted, a negative pressure is generated in the intermediate storage chamber  150   a , and the mixed cosmetics in the container storage space  111   a  flow into the intermediate storage chamber  150   a.    
     A conventional receptacle for mixing different materials having the above-described configuration is disclosed in a Utility Model Application No. 2002-0015583 (Title of Utility Model: MIXED COSMETIC CONTAINER). 
     However, according to the conventional container for mixing different materials, since different materials are mixed by a method of lowering the auxiliary storage space sealing plate portion  162  though the operating rod  146 , the opening and closing recessed groove portion  147 , and the straw support tube  148 , which are installed in the cylinder  150 , there has been a problem in that the configuration for mixing different materials is complicated and the product is difficult to assemble. 
     Since the operating rod  146 , the opening and closing recessed groove portion  147 , and the straw support tube  148  are disposed in the cylinder  150 , there has been a problem in that the size of the intermediate storage chamber  150   a  is reduced due to the configuration of mixing different materials.
