When removing the contents, after the contents are extruded, when the body is restored to its original shape, the contents that have touched the air remaining in the plug body return to the tube and return to the tube. There was a drawback that the outside air was air bagged.
Therefore, in order to prevent this phenomenon, a tube with a valve for preventing backflow, in which a spherical valve is housed in a plug body fitted into the mouth of the tube, has been developed.

Is extremely small, Y / X × 100 = 30-50%
With such a configuration, it was impossible to forcefully insert the sphere 55 from the passage 57 into the storage portion 53 of the plug main body 52. Therefore, when the plug main body 52 is molded, it has to be divided into two parts and molded as a two-part body, and the spherical valve 55 has to be inserted from the upper opening of the storage part 53. Therefore, after storing the spherical valve 55 in the storage part 53,
There is a disadvantage that the work of fitting and assembling 4 is required, which increases the manufacturing cost. (2) Since the diameter of the passage 57 opened to the bottom 56 of the plug main body 52 is small, when pushing out the contents, the tube 5
There is a drawback that the contents are not discharged to the outside through the stopper body unless the body of the 0 is pressed with a strong force, and when pressed with a strong force, the contents are suddenly discharged from the mouth, and the surroundings are the contents. There was a drawback of getting dirty.
