ABSTRACT:
To provide an adhesive fastener which has no need of a vacuum cup or a tab, an adhesive fastener 1 comprises a body member 2 and a tank member 3. The tank member 3 forms an adhesive container 10 in which adhesive material is contained. One end of the tank member is open but the other end is closed by a rigid end wall 13 and a frangible thin portion 14. The body member 2 has a plunger 18 which is slidably inserted from the opening side into the adhesive container 10 and forces out the adhesive from the frangible end, and an adhesive surface 22 which is formed outside the tank member so as to move together with the plunger and comes into contact with the surface of an attachment member to be bonded to the attachment member by means of the adhesive material. On the frangible end of the tank member, a protrusion 6 protruding axially outwardly is provided in the center or axis. In the initial state that the adhesive material contained in the adhesive container 10 is sealed by the plunger 18, the adhesive surface 22 is positioned farther from the frangible end than the surface of the attachment member is. When the protrusion 6 is brought into contact with the attachment member and the body member 2 is pressed, the plunger 18 presses the adhesive material in the tank member and breaks the frangible thin portion 14 to cause the adhesive to material flow out onto the surface of the attachment member. When the body member is pressed further, the adhesive surface comes into contact with the surface of the attachment member and is fixed to the attachment member by means of the adhesive which has flowed out.
