 the sealing portion comprises:   a support layer located adjacent to the inner upper surface of the cap portion and having an empty space in a middle part; and   an airtight sheet adhered to the support layer to cover the empty space of the support layer and adhered to an upper end of the holding part to cover the open upper part of the holding part.   
     
     
         10 . The receptacle of  claim 9 , wherein
 the sealing portion further comprises a blocking portion extending downward from a lower part of the support layer and disposed to be in contact with an inner side surface of the mounting portion.   
     
     
         11 . The receptacle of  claim 1 , wherein
 the sealing portion comprises:   a first part having a first thickness and adhered to an upper end of the holding part to cover an upper part of the holding part; and   a second part having a second thickness greater than the first thickness, surrounding the first part, and having a lower surface in contact with an upper end of the mounting portion.   
     
     
         12 . The receptacle of  claim 11 , wherein
 the sealing portion further comprises a blocking portion extending downward from a lower part of the support layer and disposed to be in contact with an inner side surface of the mounting portion.   
     
     
         13 . An auxiliary contents holding device comprising:
 an auxiliary contents holding portion including a holding part having an open upper part and holding auxiliary contents, a support portion located to surround the holding part to support the holding part, and a mounting portion connected to the support portion and coupled to an upper end of a receptacle;   a support layer located above the mounting portion; and   an airtight sheet adhered to a lower surface of the support layer and sealing an upper part of the holding part.   
     
     
         14 . The auxiliary contents holding device of  claim 13 , wherein
 the airtight sheet is formed of a transparent material.   
     
     
         15 . The auxiliary contents holding device of  claim 13 , wherein
