すように構成されたものである。[Prior Art] There is a stretched container in which a stopper is heat-sealed to the flange of the container opening. For example, a container that seals and packages an infusion solution is equipped with a stopper through which a hollow needle-shaped object is inserted when the contents are used. As such a container, for example, there is a container 10 shown in FIG. A plug body 4 made of an elastic resin material such as polypropylene is attached to a horizontal annular flange 3 by heat sealing, as shown in detail in FIG. 4, for example. The plug body 4 is configured such that after the sealing material 5 is peeled off, the hollow needle-like body pierces the thin wall portion 6 to take out the contents.

着させこの状態で固化させる方法である。In such a container, when the stopper is heat-sealed to a flange formed at the opening of the container and made of a thermoplastic resin material, the method shown in FIG. 3 has conventionally been used. That is, as shown in FIG. 3(a), with the stretched bottle 10 supported by the holder 108 and the surfaces of the flange 3 and the stopper 4 to be bonded facing each other, as shown in FIG. 3(b)
As shown in Fig. 3(C), both surfaces to be bonded are heated with a heater 7 located between the two, and as shown in Fig. 3(C), with both surfaces to be bonded melted, the plug body 4 is pressed against the flange 3 and bonded. This is a method of solidifying in this state.

For this reason, there is a problem in that the flange 3b that is solidified after adhesion has a small adhesion area with the plug, which may result in poor sealing.

The purpose of the present invention is to provide a plug sealing method that is free from the risk of seal failure.

特徴としている。(B) Structure of the Invention [Means for Solving the Problem] Corresponding to this object, the stopper seal of the present invention is provided by heating the stopper to a flange formed at the opening of a container and made of a thermoplastic resin material. This plug sealing method is characterized in that the heat sealing is performed while the heat sealing side surface of the flange is heated and the opposite surface is cooled.
以下、この発明の詳細を一実施例を示す図面について説
明する。Hereinafter, details of the present invention will be explained with reference to the drawings showing one embodiment.
第１図は、栓体４を、この発明の一実施例に係わる栓体
シール法によってヒートシールされる直前の延伸ボトル
１のフランジ３付近の状態を示す拡大図である。FIG. 1 is an enlarged view showing the vicinity of the flange 3 of the stretched bottle 1 immediately before the stopper 4 is heat-sealed by the stopper sealing method according to an embodiment of the present invention.

れている。The flange 3 has a surface 11 on the side where the plug body 4 is heat-sealed.
is heated to a temperature at which the material constituting surface 11 melts, for example 170° C. in the case of polypropylene, and the opposite surface 12 is cooled and maintained at a temperature lower than said melting temperature, for example about 140° C. , supported by a holder.

℃に保っているものである。That is, the holder 8 supports the stretched bottle 1 by contacting the entire circumference of the surface 12, but an air flow passage 13 for air cooling is formed inside the holder 8; It has a plurality of open ends 14 at positions facing the surface 12. The open ends 14 are uniformly distributed in the width direction and circumferential direction of the surface 12, and room temperature air flowing through the flow path 13 is blown out from the open ends 14 toward the surface 12, cooling the surface 12 and hitting the target 140.
It is kept at ℃.

A method of cooling the flange with cooling water or other cooling methods can also be used.

がない。[Operation/Effect] According to the plug sealing method shown in FIG. 1, the flange 3 melts the surface 11 on the side where the plug 4 is heat-sealed, and keeps the surface 12 on the opposite side unmelted. As the seal sag, the diameters of both the inner and outer contours of the flange 3 are hardly reduced, and the plug body 4 is heat-sealed in this state, so the bonding area is large enough to cause sealing failure. There is no fear.

ので経済的である。In addition, in carrying out the plug sealing method shown in FIG. 1, the equipment for implementing the conventional plug sealing method is used as is, as shown in FIGS. 2(a), (b), and (c). Holder 1
It is economical because it is only necessary to add holder 8 and air cooling equipment instead of 08.
［実験例］
