上面に溶着されるものである。That is, at the time of this welding, the contact surface 12 of the ultrasonic horn is provided on the upper surface of the lid member 5, and the ultrasonic vibration is transmitted to the lid member 5 via this contact surface 12. It is transmitted to the horizontal portion 6 of the container body 4 through the protrusions 11a and 11b which are welding ribs. At this time, the protrusion 11a and the outer periphery which are provided on the inner peripheral side of the protrusions 11a and 11b which are welding ribs are provided. Since the lower ends of the protrusions 11b provided on the side are in contact with the upper surface of the horizontal portion 6 of the container body 4, first, the liquid stored in the container body 4 is atomized by the vibration of ultrasonic waves. However, due to the presence of the protrusions 11a on the inner peripheral side, there is no risk of scattering to the outside of the protrusions 11a, so be sure that the liquid may affect the portion outside the protrusions 11a. On the other hand, the protrusion 11b, which is the welding rib on the outer peripheral side, is eliminated. It is melted by ultrasonic vibration of the container 1 and welded to the upper surface of the horizontal portion 6 of the container body 4.

ら見えないようにする覆いの役目を果たすものである。Further, at the time of this welding, the tip of the horizontal portion 6 of the lid member 5 forms the hanging portion 10, so that the portion of the hanging portion 10 which is protruded by melting the outer peripheral projection 11b flows out. To prevent the above-mentioned phenomenon and increase the welding strength, and also to serve as a cover to prevent the external view.

器本体４と蓋部材５とは確実に溶着されるものである。Therefore, using the two protrusions 11a and 11b as described above,
The protrusions 11a on the inner peripheral side prevent the liquid stored in the container body 4 from being atomized and scattered during ultrasonic vibration to hinder the welding, and the protrusions 11b on the outer peripheral side are melted to prevent the container body from melting. The container body 4 which is the object to be welded 3 and the lid member 5 are reliably welded to each other.

なお、溶着時の超音波振動数は14〜16KHz、超音波発
振振巾は20〜60μｍが好ましいものである。The ultrasonic vibration frequency during welding is preferably 14 to 16 KHz, and the ultrasonic oscillation amplitude is preferably 20 to 60 μm.

ぐれた効果を有するものである。Since the present invention is configured as described above, ultrasonic waves can be applied while the liquid is stored inside the container body to weld the container body and the lid member located on the upper part of the container body. As a result, the inside of the container body can be hermetically sealed, and since the hanging portion is provided on the outer peripheral edge of the lid member, the welding ribs on the outer peripheral side are prevented from melting and flowing out to increase the welding strength. In addition to being possible, it has an excellent effect such as good appearance.
