Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the improvement of a pillow container with a stopper used as a container for intravenous medicine or blood, or a container for functional foods, etc. .

(Prior technology) Glass bottles have been used for a long time as containers for intravenous medicine and blood, but recently flexible plastic containers called pillow containers have become popular because they are hard to break and easy to handle. It is being done.
An example of this pillow container is shown in Japanese Patent Publication No. 62-53189, and it is usually a pillow-shaped bag with a plurality of thin spouts called sleeves provided at the bottom. However, such containers tend to leak from the joints between the plurality of sleeves and the bags, raising concerns about airtightness. In addition, these multiple sleeves are used to individually pierce an infusion needle and a mixture injection needle, and while this type of container is preferred in American countries, it is not used in Japan. In connection with the dexterity of nurses and others, a type of container that has a single stopper inserted with an infusion needle and a mixture injection needle is used, similar to the case of conventional glass infusion bottles. They tend to be liked. To achieve this, it is necessary to increase the diameter of the plug, but when the plug is made larger, the joint with the bottom of the pillow-shaped bag also becomes larger.
There was a drawback that the chemical solution remained in this area at the end, making it difficult to completely drain it.

(Problems to be solved by the invention) The present invention solves these conventional drawbacks, and despite having a large-diameter stopper that can be penetrated by an infusion needle and a mixture injection needle, the bottom of the bag This was completed in order to provide a pillow container with a stopper that can be completely discharged without leaving any chemical liquid, etc. in the container, and has excellent airtightness and bag-making properties.

(Means for Solving the Problems) The present invention for achieving the above-mentioned problems is a pillow container with a stopper attached to the bottom of a pillow-shaped bag made of flexible plastic,
The stopper has a large diameter that can be penetrated by an infusion needle and a mixture injection needle, and the upper part of the stopper has a seat with an elongated communication opening that narrows in width in the direction of the bag's curvature. It is characterized by being joined to the bottom part.

(Example) Next, the present invention will be explained in more detail with reference to the illustrated example.

1 is a pillow-shaped bag made of flexible plastic material such as ethylene, propylene, polyolefin, etc., and around it is a sealing part 2.
The sealing part 2 is sealed to have an airtight structure, and a hanging part 3 is formed by cutting out a part of the sealing part 2 at the upper part of the sealing part 2. The bottom of the bag 1 is made of curved plastic material, and a stopper 4 is provided at that part.

In the present invention, for the reason mentioned above, the plug body 4
has a large diameter that allows the infusion needle and the mixture injection needle to be pierced therein, and the portion of the rubber 5 through which these needles are pierced is circular. However, the upper part 6 of the plug body 4 has an elongated shape with a narrow width in the direction of curvature of the bag 1, and is joined to the curved bottom part of the bag 1 by a seat 8 having a communication opening 7 having such a shape. There is. The seat 8 is a flat plate integrated with the upper part 6 of the plug body 4, and its large area is joined to the curved bottom part of the bag 1, so that high airtightness is ensured. The upper part 6 of the stopper 4 shall have a sufficient height to prevent the tip of the needle from reaching the curved bottom of the bag 1 even when an infusion needle or mixed liquid injection needle is inserted therethrough. do.

(Function) The pillow container with a stopper of the present invention configured as described above can be used when the inside of the bag 1 is filled with a drug solution, blood, functional food, etc., and when administering an intravenous drip to a patient in a hospital bed. For example, in the case of an intravenous drip, the hanging part 3 at the top is hung on a hook, and the infusion needle and mixed liquid injection needle are inserted through the rubber part 5 of the large-diameter stopper 4 at the lower end. This system supplies the internal medical solution and blood into the patient's body while mixing it with the medical solution. In this way, in the present invention, the large-diameter stopper 4 is joined to the curved bottom of the bag 1, unlike the type in which the infusion needle and the mixed liquid injection needle are inserted into separate sleeves. , it can be used without any discomfort in Japan. In addition, in this type of pillow container, as the medical solution etc. inside flows out, the walls on both sides gradually come into close contact with each other from the upper end of the bag 1. However, in the present invention, the upper part 6 of the stopper 4 By the seat 8 having the narrow communication opening 7 in the direction, the bag 1
Because it is joined to the curved bottom of the
The bottom part of the stopper body 4 can also be deformed to a nearly intimate state without being hindered by the upper part 6 of the stopper body 4. Therefore, the pillow container with a stopper of the present invention can completely drain out the medical solution, etc. inside. Furthermore, in the present invention, the plug body 4 has a seat 8 having a large area.
Since it is connected to the bottom of bag 1 by
Unlike the conventional bag with multiple sleeves joined together, it has excellent airtightness and can be stored for a long period of time without causing any change in the contents.

(Effects of the invention) As explained above, this invention has a large-diameter stopper, so that it can be pierced with an infusion needle and a mixed liquid injection needle when in use, and can be used without any discomfort even in Japan. In addition, since the bottom of the bag can be deformed into a flat state without being obstructed by the stopper, the medicinal solution etc. inside can be completely drained to the end. In addition, the pillow container with a stopper of the present invention has excellent airtightness, and since the stopper is joined by a seat with a large area, it also has excellent bag-manufacturability.

Therefore, the present invention has extremely great practical value as a pillow container with a stopper for medical or functional foods that solves the problems of conventional pillow containers of this type.
