は医療用途には使用できなかった。[0003] This vinyl chloride resin lacks stability against heat and light, so metal soap is added to improve moldability. However, vinyl chloride resin compositions using cadmium soap or lead soap as metal soaps are toxic and cannot be used for packaging materials or containers that come into direct contact with food or for medical purposes.

た。[0004] Therefore, vinyl chloride resin is used for food packaging materials, food containers, medical packaging materials, equipment, etc., for example, by attaching it to the entrance and exit of flexible containers to block the liquid content, and to close the closed part. When used in closed parts that can be easily broken to open the entrance/exit by bending, metal soaps other than cadmium soap or lead soap, such as calcium soap, zinc soap, magnesium soap, barium soap, etc., should be replaced with vinyl chloride soap. It was used by adding it to the resin.

石鹸や鉛石鹸を添加した塩化ビニル系樹脂組成物に比べ
熱安定性がそれほど高くない。[Problems to be Solved by the Invention] By the way, the above-mentioned metal soaps other than cadmium soap and lead soap all have a considerably smaller thermal stability effect on vinyl chloride resins than cadmium soap and lead soap. Therefore, non-metallic stabilizers such as polyhydric alcohol, trisnonylphenyl phosphate, aminocrotonic acid ester, diphenylthiourea, pentaerythol adipate, and pentaerythol are used in combination with these metal soaps. However, even such vinyl chloride resin compositions do not have much higher thermal stability than vinyl chloride resin compositions containing cadmium soap or lead soap.

場合には成形加工に長期作業を要している。[0006] Therefore, the above-mentioned metal soaps other than cadmium soap and lead soap are used in combination with epoxidized soybean oil. When used as a resin, the softening point is lowered. Furthermore, a combination of calcium soap or barium soap with zinc soap not only has insufficient thermal stability, but also tends to cause initial discoloration. In addition, a dioctyltin stabilizer is sometimes used, but in this case, a long period of work is required for the molding process.

ば破断されないといった不都合があった。As described above, vinyl chloride resin compositions using non-toxic or low-toxic heat stabilizers other than cadmium soap or lead soap do not necessarily have sufficient thermal stability, and the vinyl chloride resin is It easily deteriorates due to heat, and tends to cause discoloration and quality of molded products due to heat deterioration. In addition, these vinyl chloride resin compositions were not designed with special consideration given to the bending breakability of the above-mentioned closing parts, so when bending and breaking, it is difficult to completely break the broken part by just bending it in one direction. First, it had the disadvantage that it had to be bent further in the opposite direction, and that it would not break unless a considerable amount of force was applied with both hands.

Then, force is applied manually from the outside of the conduit to bend the blocking component, thereby breaking the broken portion of the blocking tubular body. As a result, the inlet/outlet of the container becomes open, allowing the fluid in the container to flow out. By the way, regarding the shape and dimensions of the groove of the broken part provided on the outer periphery of the closed cylindrical body in the closed part made from the vinyl chloride resin composition of the present invention, the bottom width of the groove is set to 0 to 1. .5 mm, the minimum wall thickness of the closed cylindrical body in the groove of the broken part is 0.35 to 0.6 mm, and the side surface on the fixed part side of both sides of the groove of the broken part has an inclination angle of 25 to 9.
It is preferable that the angle of inclination is 0°, and the side surface on the fixed part side has an inclination angle of 45 to 90°. Note that the inner diameter of the closed cylindrical body at the fractured portion is generally 5 mm or less. By configuring the shape and dimensions of the groove in the breakage portion as described above, the closure component made of the vinyl chloride resin composition can be operated with one hand and exhibits better bending and breakability.

成を示しており、１は閉塞部品、２、３は導管である。Next, the closure component of the present invention will be explained with reference to the drawings. FIG. 1 shows the overall structure of this closure component, where 1 is the closure component, and 2 and 3 are conduits.

１２、他方が固定部１３とされている。The closing component 1 is composed of a closing cylindrical body 10 made of a cylinder with one end closed, and a locking portion 14 formed on the outer periphery of the opening side edge of the closing cylindrical body 10. A broken portion 11 is formed on the outer periphery of the closed cylindrical body 10 by cutting a groove 16 along the circumferential direction approximately in the center thereof. One side of the broken part 11 is a closing part 12, and the other part is a fixed part 13.

中空でなければならない。The closing portion 12 has a cylindrical shape with a diameter smaller than that of the fixing portion 13, so that the closing portion 12 after rupture can be easily separated from the fixing portion 13 and moved within the conduit 2. Moreover, it is formed so as to become tapered toward the end. This facilitates insertion of the closure component 1 into the conduit 2. Regarding the closed state of the closed portion 12, the entire interior may be in a cylindrical state and only the end side may be closed, or as in this embodiment, almost the entire interior may be closed to prevent the interior from becoming too cylindrical. It's okay. However, the inside of the broken part 11 must be cylindrical and hollow.

方向に沿って形成されている。The fixing portion 13 has a cylindrical shape with a diameter approximately equal to or slightly larger than the inner diameter of the conduit 2 so that the closure component 1 can be inserted into the conduit 2. Further, a flange-shaped locking portion 14 is formed along the circumferential direction on the outer periphery of the end portion of the fixing portion 13 so as to prevent the fixing portion 13 from entering the conduit 2 in this inserted state.

A conduit 3 having a smaller diameter than the conduit 2 can be fitted and fixed into the fitting groove 15 . Note that this conduit 3 is a guide tube for draining the content liquid. Further, in order to stabilize the fitted state of the conduit 3, a portion inside the fitting groove 15 is further protruded to form an insertion portion 19 that can be fully inserted into the conduit 3. .

えるような広さになると成形が困難となるからである。As shown in an enlarged view in FIG. 2, the groove 16 of the broken part 11 has an inclined surface 17 formed on the closing part 12 side, an inclined surface 18 formed on the fixed part 13 side, and a bottom part (no bottom part). (in some cases), it is almost wedge-shaped. As for the minimum thickness t of the groove 16 portion of the cylindrical body 10, a thinner one is preferable for breakage, but if it is formed too thin, there is a risk of accidental breakage when not in use. It becomes difficult to do so. On the other hand, if it becomes thick, it will not be easy to break it with one hand. Therefore, this groove 16
The thickness t of the portion is preferably in the range of 0.35 to 0.6 mm. Further, the inner width l of the groove 16 is 0 to 1.
．． Preferably, the range is 5 mm. This is because molding becomes difficult if the width exceeds 1.5 mm.

好ましい。The inclination angle β of the side surface 17 on the side of the closed portion 12 is 4.
The angle of inclination α of the side surface 18 on the fixed portion 13 side is preferably in the range of 25 to 90°. As shown in the figure, it is preferable that the inclination angle α of the side surface 18 on the fixed part 13 side is smaller than the inclination angle β of the side surface 17 on the obstructing part 12 side because bending and breakage properties are excellent.

If it exceeds 5 mm, it may be difficult to bend it with one hand. As a material for such a closure component 1, the above-mentioned vinyl chloride resin composition is used.

The contents of these containers can be stored in a sterile state.

Using the vinyl chloride resin compositions of Examples 1 to 4 and Comparative Examples 1 to 9 as materials, closed parts having the shapes shown in the figures were molded by injection molding.

(minimum scale: 0.2 kg, maximum scale: 20 kg) was used. A load was applied to the closed part near the broken part, and the load when the broken part 11 broke and broke was measured. Note that the measurements were performed at room temperature.
