Assembly-type application device and method for using the same

Abstract

An assembly-type application device for a cosmetic product and a method for using the same are disclosed. The assembly-type application device includes a hollow application member, an elastic body, a sealing member, and a holding member. The elastic body is filled in the hollow application member and the hollow application member becomes resilient in the presence of the elastic body. The sealing member is in sealing contact with the hollow application member to maintain the elastic body in the hollow application member. The holding member is coupled with the hollow application member via the sealing member. Every time the assembly-type application device is used, a usage amount of the cosmetic product can be reduced, and the assembly-type application device is easily cleaned after being used.

What is claimed is: 
     
         1 . An assembly-type application device for a cosmetic product, comprising:
 a hollow application member having a contact surface for applying the cosmetic product to a desired area of skin;   an elastic body filled in the hollow application member, wherein the hollow application member becomes resilient in the presence of the elastic body;   a sealing member in sealing contact with the hollow application member to maintain the elastic body in the hollow application member; and   a holding member coupled with the hollow application member via the sealing member.   
     
     
         2 . The assembly-type application device of  claim 1 , wherein the hollow application member has an opening corresponding in location to the contact surface for receiving the elastic body, and the sealing member seals the opening. 
     
     
         3 . The assembly-type application device of  claim 2 , wherein the hollow application member includes a main body portion with the contact surface and a connecting portion with the opening, and the connecting portion integrally extends from the main body portion. 
     
     
         4 . The assembly-type application device of  claim 3 , wherein the main body portion has an outer diameter greater than that of the connecting portion. 
     
     
         5 . The assembly-type application device of  claim 3 , wherein the sealing member includes a stop portion and a first engagement portion integrally extending from the stop portion, the stop portion has an outer diameter greater than that of the first engagement portion, and the stop portion fittingly abuts against the connecting portion and the first engagement portion sealingly engages with the opening. 
     
     
         6 . The assembly-type application device of  claim 5 , wherein the holding member is rod-shaped and has a front end connected to the stop portion of the sealing member. 
     
     
         7 . The assembly-type application device of  claim 6 , wherein the stop portion of the sealing member has an engagement recess, and the front end of the holding member has a second engagement portion a part of which is fitted in the engagement recess. 
     
     
         8 . The assembly-type application device of  claim 7 , further comprising an annular connecting member surroundingly coupled to the connecting portion of the hollow application member, the stop portion of the sealing member, and another part of the second engagement portion of the holding member. 
     
     
         9 . The assembly-type application device of  claim 8 , wherein the annular connecting member has an inner peripheral surface adhered to outer peripheral surfaces of the connecting portion, the stop portion, and the another part of the second engagement portion. 
     
     
         10 . The assembly-type application device of  claim 1 , wherein the hollow application member is made of a soft plastic material. 
     
     
         11 . The assembly-type application device of  claim 1 , wherein the elastic body is made of a resilient material. 
     
     
         12 . A method for using an assembly-type application device, comprising the steps of:
 providing the assembly-type application device which includes a hollow application member, an elastic body, a sealing member, and a holding member;   inserting the elastic body into the hollow application member;   sealing the hollow application member by the sealing member to maintain the elastic body in the hollow application member;   coupling the holding member to the hollow application member via the sealing member by adhering; and   operating the holding member to bring the hollow application member apply a cosmetic product to a user's face
