するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a plastic container for infusions and a method for manufacturing the same, and more particularly to a plastic container for infusions having a stopper containing a rubber stopper in the opening and manufacturing thereof. It is about the method.

いう技術が知られている。When conventional rubber stoppers come into direct contact with infusion fluids, they elute harmful components such as sulfur, which is extremely unsuitable from a sanitary standpoint.In general, the surface of rubber stoppers is coated and sealed to prevent direct contact with infusion fluids. There is. One way to do this is to form a synthetic resin film directly on the surface of the rubber stopper to cover it (Special Publication Publication No. 38
As shown in Fig. 5, a technique is known in which a thin film is disposed on the bottom surface of the rubber stopper a, and the top surface C of the rubber stopper is sealed by injection molding (Japanese Utility Model Publication No. 58-37396). It is being

われるという問題があった。Problems to be Solved by the Invention However, the above-mentioned conventional plastic containers for infusion still have problems. In other words, since the plastic container for infusion according to the prior art mentioned above is made of a synthetic resin coating, the wall thickness is inevitably thin, so the strength of the coating is low, so it easily tears and the rubber stopper is exposed, making it unhygienic. In addition, in the latter prior art infusion plastic container, the rubber stopper a is sealed by injection molding through a thin film, which prevents bacteria from entering from the outside. Although it can be prevented, if the infusion inside is thin, it will very easily penetrate into the rubber stopper from between the injection molded part C', and the infusion will contain the above-mentioned harmful components of the rubber stopper, and the infusion will enter the inside infusion. There was a problem in that the sanitary properties of the internal infusion solution were impaired due to the reverse reaction.
一方、上記従来技術の輸液用プラスチック容器の製造方

るのである。On the other hand, the above-mentioned conventional method for manufacturing a plastic container for infusion has the following problems. In other words, in the manufacturing method mentioned above, since the surface of the rubber stopper is coated with synthetic resin, the coating process takes a long time, especially when finishing a thick one.
The latter manufacturing method has the problem of being time-consuming, and since the elastic rubber stopper a is inserted and injection molded, the rubber stopper a may be deformed due to the injection pressure, or the rubber may deform due to the heat of melting the synthetic resin. The problem is that it decomposes.

ることを目的とするものである。Therefore, in the plastic container for infusions of the present invention, the sealing state of the rubber stopper will not be impaired even if it is used excessively. It is an object of the present invention to provide a plastic container for infusions having a stopper with extremely high sealing performance, and the method for manufacturing a plastic container for infusions of the present invention is capable of easily sealing a rubber stopper in an extremely short time. The purpose of this invention is to obtain a manufacturing state in which the sealing state can be maintained for a long period of time, and the rubber stopper does not deform during manufacturing.

である。Means and Effect for Solving the Problems Therefore, the plastic container for infusions of the present invention has a stopper containing a rubber stopper in the opening, and the plastic container for infusions has hygienic features on the top and bottom surfaces of the rubber stopper. A tall plastic sheet is arranged, the ends of which are brought into close contact with each other are extended laterally, and this end is compressed by a flange at the mouth of the container and an annular valve plug, and a welded part is formed on the outside of the sheet. Since it is a sealed rubber stopper, the sealing properties of the rubber stopper are achieved by the close contact between two highly hygienic plastic sheets, and this sheet is strong so it will not tear due to excessive use. Moreover, since the valve stopper and the flange of the container mouth are welded together, the seal is even more perfect, completely preventing the intrusion of bacteria from the outside, and also preventing the infusion from entering the inside. , the infusion solution inside must pass between the bottom sheet and the flange of the container mouth, reach the outermost end of the container, and then enter between the two sheets, and the internal infusion liquid must enter into the rubber stopper. It is possible to prevent this from happening.

This end is placed on the flange of the container mouth, sandwiched between an annular valve stopper, and the valve stopper and the flange of the container mouth are welded to seal the rubber stopper, so the plastic sheet is used. The rubber stopper can be easily covered by arranging the valve, and the flange at the mouth of the container and the valve stopper are welded to form a tight seal, and no heat is applied to the rubber stopper, which prevents the rubber stopper from deforming. There is no possibility of decomposition.
