Abstract

PROBLEM TO BE SOLVED: To improve valve function which can support contents of low viscosity in a check-valve fitted into a mouth of a squeezing tube for preventing air from flowing back by forming an outer diameter size of a valve body to be larger than an inner diameter size of a valve hole and bringing the valve body into overlapping contact with an upper face of a thick valve seat. SOLUTION: A check-valve 1 comprises a cylinder 5 formed on a lower part of a flange 4, while the cylinder 5 is formed with a thick part 6 protruding toward a center in a radial direction at its lower end and with a valve hole 8 at a center of the thick part 6. A valve body 9 extends from near an upper end of an inner periphery of the thick part 6, wherein the valve body 9 is coupled to the thick part 6 by a coupling 10. At this time, an outer diameter size of the valve body 9 is formed to be larger than an inner diameter size of the valve hole 8, and the valve body 9 is brought into contact with a valve seat 7 of the thick part 6 so that they overlap. This prevents the valve body 9 from being sucked into the valve hole 8 to be inverted when a tube container 2 has air flowing back, thereby reliably preventing air from flowing back into the tube container 2.

れることは言うまでもない。As a check valve of such a tube with a check valve, there is a check valve shown in FIGS. 4 (a) and 4 (b). In FIG. 4, reference numeral 50 denotes a check valve, and the check valve 50 has a structure in which a flange portion 51 for crowning the upper end of the mouth portion of the tube container is formed, and below the flange portion 51, and A tubular portion 52 extending into the mouth of the tube container, a thick portion 53 provided at the lower end of the tubular portion 52 and protruding toward the center in the radial direction, a valve hole 54 formed by the thick portion 53, and this valve. The valve body 55 extends from the vicinity of the upper end of the inner circumference of the thick portion 53 so as to close the hole 54, and the valve body 55 and the thick portion 53 are integrally connected by a narrow connecting portion 56. . It is needless to say that the outer diameter of the flange portion 51 is formed so as to be smaller than the outer diameter of the male screw of the mouth portion when it is capped on the mouth portion of the tube container.

６の成形が極めて容易となった。The feature of the first invention of the present application is that, as shown in FIG. 2, the outside diameter dimension D1 of the valve body 9 is changed to the inside diameter dimension D2 of the valve hole 8.
It is formed in a larger size, and the valve element 9 is in contact with the valve seat 7 of the thick wall portion 6 so as to overlap. That is, the valve body 9 is brought into contact with the valve seat 7 in an overlapped state.
The larger the dimension difference H between the outer diameter dimension D1 of the valve body 9 and the inner diameter dimension D2 of the valve hole 8, the larger the area in which the valve body 9 contacts the valve seat 7, and the function of the valve body 9 is improves. However, when the valve body 9 is integrally formed with the flange portion 4, the tubular portion 5, and the thick wall portion 6, the outer diameter dimension D1 of the valve body 9 is formed.
Is larger than the inner diameter dimension D2 of the valve hole 8, the tip of the valve body 9 is caught in the mold when the check valve 1 is pulled out from the mold, and the valve body 9 and the thick wall portion 6 are connected to each other. There is a problem that excessive force is applied to the thin connecting portion 10 and the connecting portion 10 is broken. Therefore, conventionally, the outer diameter dimension D1 of the valve body 9 and the inner diameter dimension D2 of the valve hole 8 are formed to have substantially the same dimension,
Although it was designed not to be caught when it is taken out from the mold, the valve function was insufficient as described above. The present inventors have made the outer diameter dimension D1 of the valve body 9 larger than the inner diameter dimension D2 of the valve hole 8 by improving the structure of the mold for molding the check valve 1 and the tube shoulder 16 with the check valve. Even in such a case, when pulling out from the mold, an excessive force is not applied to the connecting portion 10 and a device is devised so as not to break. In addition to improving moldability, we have devised a mold that allows multiple products to be produced simultaneously by simultaneous molding and has a long life. As a result, the check valve 1 and the tube shoulder 1 with the check valve according to the present invention are provided.
The molding of No. 6 became extremely easy.

3 constitutes a tube shoulder 16 manufactured by integral molding. The shoulder portion 16 has a structure in which a thick wall portion 14 that projects toward the center in the radial direction is formed integrally inside the vicinity of the boundary between the mouth portion 11 and the shoulder portion 12, and the thick wall portion 14 has a valve hole. 15 is formed.
The valve body 13 extends from the vicinity of the upper end of the inner circumference of the thick portion 14, and the valve body 13 and the thick portion 14 are integrally connected by a narrow connecting portion 17. Also in the second aspect of the invention, the outer diameter of the valve body 13 is larger than the inner diameter of the valve hole 15 (dimension difference H). After the tube shoulder 16 with the check valve is molded, the separately molded body portion 19 is welded to the lower end of the shoulder portion 12, or the body portion 19 molded simultaneously with the shoulder 16 is welded to the lower end of the shoulder portion 12. By doing so, a desired tube container is produced.

The valve function of the molded check valve 1 was extremely good, and it was possible to exhibit a good valve function even for low-viscosity contents. Further, the work of extracting the check valve 1 from the mold was extremely easy, and no damage was observed in the connecting portion 10 during the removal. When the outer diameter of the valve body 9 is set to 0.25 mm to 0.5 mm (dimension difference H) from the inner diameter of the valve hole 8, the moldability of the check valve 1 in the mold is also good, and at the same time. 16 pieces can be taken.
