[Means for Solving the Problems]

 According to the present invention, in a plastic stopper that seals the upper opening of an infusion container, a main plug that connects the cylindrical body of the infusion container and closes the upper opening of the same is used, while the lower bottom has a large-diameter ring. Is formed, and a tubular cylindrical portion protruding upward is formed at a position biased to one side of the lower bottom portion, and the inner hollow portion is formed as a hollow portion inside the tubular trunk portion. A shaft portion is established in the center of the upper lid portion that blocks the opening of the upper end of the inner hollow portion of the tubular cylindrical portion by making them communicate with each other and integrally forming with the upper end of the protruding tubular cylindrical portion. , The knob is integrally connected to the outer end thereof, and the thickness of the portion where the upper lid portion is connected to the shaft portion is thin, and the lower bottom portion is formed on one side of the tubular cylindrical portion. The annular body protruding toward the central part of is integrally provided.

In the plastic stopper constructed as described above, by placing a finger inside the ring of the annular body protruding from the cylindrical portion and pulling it toward the outside of the tubular cylindrical portion, The part of the notch near the base of the part is cleaved first, while the lower bottom is being flipped up, the annular notch is easily cleaved, the entire main body of the stopper is separated from the tubular body, and the upper end of this body is cut off. A wide-mouthed opening is formed in the container to facilitate the opening of the infusion container.

On the other hand, apart from the above operation, by twisting the knob on the top end of the cylindrical portion, the thin portion of the upper lid portion on the peripheral side of the shaft portion is torn off, and if the knob is removed together with the shaft portion, it will be biased. A narrow mouth opening is formed at the top end of the cylinder where it is located, which makes it extremely easy to open the infusion container, and the opening is formed in a position biased to one side, so that the solution in the infusion container can be easily removed. The directivity when ejecting toward a predetermined local portion is made excellent. Even if it is opened at any of the above-mentioned parts, a single stopper body will provide the unsealing result according to each application.

[0013]

[Action]

 The infusion container with the plastic stopper of the present invention is mainly used in a medical institution such as a hospital during an operation, but an operator who has already undergone sterilization work can further use the palm or fingers before the operation. In order to make the container aseptic or to further clean the sterilized surgical instrument to make it completely aseptic, open the infusion container mainly containing physiological saline and allow the contents to flow. It is not only used when opening the opening of the infusion container with a wide mouth and using it at a high flow rate, such as when cleaning by washing, but also during surgery, re-disinfecting the surgical site or It is also used under a small flow rate for ejecting the content liquid for the purpose of localized intensive cleaning, such as cleaning and rinsing the bleeding that has flowed out to the surrounding area.

In the plug body of the present invention having the above-mentioned structure, when the palm portion and fingers are used under a large flow rate for cleaning, the fingers are put inside the ring of the ring-shaped body 22. When pulled upward from the cylindrical portion 27, the cleavage starts from the portion of the notch 125 on the side close to the base of the cylindrical portion 27, and the cleavage of the annular notch 125 progresses as the lower bottom part turns up, and the plug main body 24 Is separated from the tubular body portion 23 to form a wide mouth (pull-off opening). This allows the liquid in the infusion container 1 to flow at a large flow rate.

Separately from this, in a case where a small amount of liquid is flown by intensively ejecting the content liquid to a local portion such as an affected part, a surgical site or the periphery thereof, an annular cut is made. When the knob 26 protruding to the top end is twisted without tearing 125, a twisting stress acts on the annular groove 128 of the upper lid 28 via the shaft 29, and the groove 128 causes The thin upper lid portion 28 is torn off, the knob 26 is removed together with the shaft portion 29, and the narrow mouth is opened (twist opening). As a result, an opening having a small diameter is formed at the top end of the stopper main body 24, and by utilizing the inherent elasticity of the infusion container 1 to compress it, the content liquid can be vigorously ejected.

[0016]

[Effect of device]

 According to the plastic stopper of the present invention, if it is necessary to increase the flow rate with respect to the infusion container to which the plastic stopper is attached, simply insert the fingertip into the portion of the annular body 22 forming the inner hole and pull it up. It is possible to remove the plug main body 24 by cleaving the annular notch 125, and to form an open state by forming a wide mouth opening connected to the cavity 33 having a large inner diameter at the base thereof. . In this case, in the unsealing work, the annular body 22 can be used to perform the tearing work on the notch 125 with a relatively small external force, so that the number of operations can be reduced. On the other hand, by twisting the knob 26 to twist off the upper lid portion 28 facing the annular groove 128 and removing the knob 26 together with the shaft portion 29 from the plug main body 24, the top end of the cylindrical portion 27 is connected to the cavity 37 having a small inner diameter. It is also possible to form an opening with a narrow mouth, which is opened. Therefore, a single infusion container can be used to form a wide-mouthed opening suitable for discharging the contents of the container in order to clean the palms and fingers, if necessary. On the other hand, it becomes possible to form a narrow opening that helps to eject the liquid in the container.

In this way, the infusion container prepared for the surgery may be confused with the other infusion container for cleaning the palms, fingers or surgical instruments and for cleaning the affected part, the surgical site or its surroundings. As a common infusion container for each application, there is an advantage that the preparatory work can be performed quickly and easily even in the case of emergency surgery, and the stopper of the present invention is provided for storing the infusion container. It is sufficient to store a single type of product, which simplifies inventory management, saves storage space, and contributes to economic effects.
