DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, the chemical solution storage container 1 is composed of a container body 2, a first injection / discharge port 3, and a second injection / discharge port 4. The container body 2 is formed by fusing four ends of a soft plastic inflation film by heat fusion, high frequency fusion, ultrasonic fusion, or the like. Note that the upper end fusion portion 5 is initially heat-sealed, high-frequency fused, or ultrasonic, leaving the first connection portion 51 and the second connection portion 52 of the first pouring port 3 and the second pouring port 4. Processing such as fusing is performed, and then the first pouring / dispensing port 3 and the second pouring / discharging port 4 are inserted, and then processing such as heat fusion, high frequency fusion, or ultrasonic fusion is performed. The soft plastic used for the container body 2 is not particularly limited, and examples thereof include thermoplastic materials such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, and vinyl chloride. Also good.
[0007]
The first pouring / dispensing port 3 is composed of a first pouring / dispensing pipe body 31 having both ends open and a first cap 32, and the first cap 32 has a sealing member such as a rubber plug (not shown) therein. ) Is inserted to fix one opening of the first pouring tube 31 in a liquid-tight manner. Similarly, the second pouring / dispensing port 4 includes a second pouring / dispensing pipe body 41 and a second cap 42. The material of the first pouring / extracting pipe body 31, the second pouring / exhausting pipe body 41, the first cap 32, and the second cap 42 is not particularly limited, and examples thereof include hard plastics such as polypropylene and polyethylene. The material for the sealing body such as a rubber plug is not particularly limited, and isoprene rubber, butyl rubber, silicone rubber, thermoplastic elastomer rubber, and the like.
[0008]
The chemical storage container 1 has caps for the first pouring port 3 and the second pouring port 4 on the first connecting portion 51 and the second connecting portion 52 of the upper end fusion portion 5 provided on the container body 2. After inserting the end portion on the side not provided and fixing by heat fusion, high frequency fusion or ultrasonic fusion or the like, the first connection portion 51 and the second connection portion 52 of the upper end fusion portion 5 It is obtained by forming a U-shaped slit 6 at a substantially intermediate position. The first pouring port 3 and the second pouring port 4 may be fixed after the U-shaped slit 6 is formed in the upper end fusion part 5 in advance. Thereafter, the chemical solution storage container 1 is filled with the liquid agent. Although not particularly limited, the allowable amount of the chemical solution storage container 1 is about 1.0 to 4.0 liters in volume and about 1000 to 4000 g in weight.
[0009]
The shape of the slit 6 is not particularly limited. In addition to the short U-shaped one shown in FIG. 1, the long U-shaped one shown in FIG. The thing with a hole and the rectangular shape shown in FIG. 4 are mention | raise | lifted. The dimensions such as the length and width of the slit 6 can be arbitrarily set according to the width, length and hardness of the upper end fusion part 5 and the weight of the chemical solution storage container 1 when the liquid agent is filled. Although not particularly limited, specifically, the length is set within a range of 3 to 10 mm and a width of 1 to 10 mm.
[0010]
With this slit 6, the liquid container 1 is suspended or fixed when performing infusion therapy, and separate tubes are connected from the same direction to the first port 3 and the second port 4. However, when one of them is directed in a different direction, or when different tubes are connected from different directions, the first injection port 3 and the second injection port 4 are connected at the slit 6 as a boundary. It becomes possible to turn to the direction of a tube with 51 and the connection part 52. FIG. Accordingly, since the burden on the first connection portion 51 and the second connection portion 52 is reduced, the first pouring / extracting port 3, the connecting portion 51, and the second pouring / discharging port 4 as shown in the following test example It is possible to prevent the thermal fusion, high-frequency fusion, ultrasonic fusion, or the like of the connection portion 52 from being damaged.
[0011]
In the present invention, the number of pouring ports is not limited to two. At that time, it is not necessary to provide slits between all the pouring ports, and slits may be provided only between necessary pouring ports.
[0012]
(Test example)
Test examples will be shown below to explain the effects of the present invention. First, the chemical | medical solution storage container 1 described in FIG. 1 was produced. First, two low-density polyethylene inflation films were stacked, and the four ends were fused by thermal fusion to obtain a container body 2. At this time, the first connecting portion 51 and the second connecting portion 52 of the first pouring / extracting port 3 and the second pouring / exhausting port 4 were left and fused. Then, the first pouring port 3 and the second pouring port 4 are inserted into the first connecting portion 51 and the second connecting portion 52, and the first pouring port 3 and the first connecting portion 51, the second The pouring port 4 and the second connecting portion 52 were fixed by thermal fusion, and a slit 6 was provided between the first pouring port 3 and the second pouring port 4 of the upper end fusion portion 5. The width a of the upper end fused portion 5 is 15 mm, the length of the slit 6 is 10 mm, the width is 4 mm, and the distance b between the first pouring port 3 and the second pouring port 4 is 44 mm. Thereafter, high-pressure steam sterilization was performed at 106 ° C. and 0.8 kgf / cm ² for 25 minutes.
[0013]
Next, a comparative example similar to the above was prepared except that the slit 6 was not provided, and high-pressure steam sterilization was similarly performed.
[0014]
The first injection / discharge port 3 of the chemical solution storage container 1 is fixed, and the second injection / discharge port 4 is pulled in a direction opposite to the slit 6 (perpendicular to the longitudinal direction of the injection / discharge port) at a speed of 500 mm / min. The maximum load at which any pouring port or connection was damaged was measured. As a result, the average value of 20 times was 26.3 kg. Similarly, as a result of measurement in the comparative example, the average value of 20 times was 18.2 kg.
[0015]
【The invention's effect】
The chemical container according to the present invention reduces the burden by the slit even when one of the plurality of ports for discharging is pulled in a different direction from the other ports. Breakage such as fusion, high frequency fusion or ultrasonic fusion can be prevented.
