Abstract

PURPOSE:To prevent an item to be bonded from being damaged due to ultrasonic vibration by, when specific portions of items to be bonded to each other are bonded, interposing a vibration absorbing body between a horn and an anvil at a location outside said specific portions and applying ultrasonic waves thereto. CONSTITUTION:Cosmetic material is put into an inner dish 1 for a flat cosmetic compact made from thermoplastic resin and an annular frame 2 made from thermoplastic resin is fitted on the periphery of an opening of the inner dish. Next, an aluminum laminate film 3 is bonded onto a flange 2b of the frame 2 with adhesives and an expanded sheet 4 with a diameter slightly smaller than the outer diameter of the frame 2 is placed on the film 3. The sheet 4 serves as a vibration absorbing body and its thickness is larger than the height from the upper surface of the film 3 to the top of the frame 2. At last, the dish 1 and the frame 2 are held between a horn 5 and an anvil 6 to apply ultrasonic waves from the horn 5 thereto so that the frame 2 is bonded to the periphery of the dish. In this manner, the ultrasonic waves are absorbed into the bonded part of the vibration absorbing body, so that damage etc., is not caused in the portions which are not bonded.

is placed on the cap 11, the foam 4 is further placed on top of the foam 4, the periphery of the seal 12 and the cap 11 are sandwiched between the horn 5 and the anvil 6, and ultrasonic waves are applied to the periphery of the seal 12 to the cap 11. The bonded horn 5 is recessed in the center to form a recess 5a, into which the foam 4 is inserted.

When we looked at the results of ultrasonic bonding while sandwiching the horn and anvil, there was no damage to the sealing material.

〔発明の効果〕〔Effect of the invention〕

本発明によれば、接着すべき部分超音波が加わり、振動
吸収体が介在する非接着部分では超音波が吸収されるの
で、非接着部分に損傷などの不都合が生じない。According to the present invention, ultrasonic waves are applied to the portions to be bonded, and the ultrasonic waves are absorbed in the non-bonded portions where the vibration absorber is present, so that problems such as damage to the non-bonded portions do not occur.
