困難であった。In recent years, various types of books have been produced in containers that have a virgin seal structure for the purpose of sealing the container and preventing the injection of poisonous substances after the container has been opened. And conventionally, the pouring hole & C of the container
In the case of the seam structure in which the F-le film is welded, as shown in Fig. 7, the opening (2) of the container body (1)
The inner stopper (3) (inner stopper part) fitted to the upper end is usually made of synthetic resin such as polyethylene or polypropylene, and the inner stopper (3) has a circular spout ( 4) is open. In addition, the lower surface of the inner stopper (3) is provided with the opening (2).
) into the annular first fitting @ (S) and the mouth part (
2) an annular second fitting wall (6) fitted to the outside;
The upper end of the opening (2) is fitted between the first fitting wall (5) and the second fitting ram (6), particularly in a liquid-tight manner. Inner stopper (
3) An annular groove 18+ is formed on the upper surface of the spout (4) and surrounds the spout (1), and an annular groove 18+ is formed on the outer periphery of the groove (8) and protrudes upward. Projection portion 19
1 is formed. Two annular welding protrusions are provided on the upper surface of the pouring portion 17). With the spout (4) of the inner stopper (3) closed, a V-~ film 0 formed of the same resin as the inner stopper (3) is placed, and the lower surface is shown from above as shown by the imaginary line. That is, an ultrasonic oscillation horn 03 having a planar ultrasonic oscillation surface oscillates ultrasonic waves, and this ultrasonic wave melts the welding protrusion which is the protruding end, and the sealing film on and the inside are melted by this ultrasonic wave. The seal structure with the plug (3) welded is completed. However, when welding with this method, the amount of protrusion of the welding protrusion 1 is an important factor; if the amount of protrusion is small, sufficient welding force cannot be obtained; if the amount of protrusion is large, welding force There was a risk that the film would be too strong and would be difficult to peel off. In addition, when forming the medium @ (31), there was a high possibility that unevenness would occur in the amount of protrusion in the circumferential direction of the welding protrusion 11o10, and therefore, there was a large possibility that unevenness would occur in the welding force in the circumferential direction. It was difficult to mold the medium j & (a) with a welded protrusion having a predetermined amount of protrusion.Furthermore, the amount of protrusion was extremely small, for example, about 0.2 tm, and ±0.
Management work was also difficult as it had to be managed with an error of about 0.2m.

そこで、本発明は上記問題点に鑑み、中栓（中栓部）の

When the sealing film is ultrasonically welded to the container body side at the outer periphery of the spout using ultrasonic waves emitted from an ultrasonic oscillation horn, a protrusion is formed on the ultrasonic oscillation surface corresponding to the welded portion. The point is that a striped portion is provided and ultrasonic waves are generated intensively from this projected striped portion.

条の突条部（至）が下方に突設されている。Hereinafter, the first embodiment of the present invention will be explained based on the drawings. In FIGS. 1 to 4, the company shows an inner plug (inner plug part) made of synthetic resin such as polyethylene or polypropylene, Similar to the above, it is fitted into the mouth (2) of the container body (1). In addition, as described above, the inner stopper @ integrally includes the first fitting wall (C), second fitting wall @, pouring part (to), concave groove part (to), and protrusion surface of the spout. There is. However, the welding protrusion +lO1 as in the conventional case is not formed on the upper surface of the spouting portion (to), and the upper surface is flat. 2 is a sealing film, and as shown in Figure 4, the lower surface of the polyester thread film body is coated with a resin of the same type as the inner stopper, and a coating layer of polyethylene or polypropylene resin on the side. We are prepared. ctn is an ultrasonic oscillation horn, and two protrusions (to) are provided on the lower ultrasonic oscillation surface (to) at a position corresponding to the spouting part - the upper surface to protrude downward.

). At this time, the coating layer (toward) is placed on the inner plug e2TJ side, that is, on the lower side. In that state, as shown by the imaginary line in Figure 1s1, the protrusion (to) is the spouting part ■
Ultrasonic waves are oscillated from the ultrasonic oscillation horn C11) at a position corresponding to the upper part. In this way, the energy of the ultrasonic wave is concentratedly oscillated from the tip of the protrusion (to) that is the protruding end, and the lower part and the corresponding coating layer and the upper surface of the injection part (to) are melted and bonded. At this point, the ultrasonic welding is completed and the sealing film (5) is welded to the inner plug 1211.

Furthermore, when molding the inner plug an, there is no welding protrusion that requires strict precision, and the molding is easy and the management work is also easy. Furthermore, V-
When coating with Luffy Vm (2), it is easy to obtain a coating with a stable thickness, and its management work is also easy. In addition, a polyester film is used as the main body of the seal film (■), and since polyester film has high tensile strength, it is possible to
- When peeling off the fin A/A (to), there is no risk of it being accidentally torn off from the welded part, and the peeling work is easy.

It may also be a configuration. In addition, the seal film ■ uses a coating layer ■ on the film body, but the seal film ■ formed from the same type of resin as the inner plug @ is used.
Using this book is good. Furthermore, the inner stopper (3) is the container body (1)
The inner plug (3) may be integrally formed with the mouth portion (3) of the inner plug (3), and the shape of the inner plug (3) is not limited to the shape of the embodiment.

れるという利点を奏する。As described above, the present invention is a method of ultrasonically welding a seal film to the inner plug part by placing a seal buoy on the inner plug part and intensively oscillating ultrasonic waves from the protrusion of the ultrasonic oscillation horn. Therefore, it is possible to always obtain a welded state with stable welding force, and it is also easy to mold and manage the inner plug part. Therefore, the possibility of producing defective products is reduced, and costs can be reduced.
