There is an effect of facilitating the opening of the orifice by making the outer peripheral portion of the orifice portion thicker than the shape portion.

The embodiment of the discharge valve device according to the present invention will be described below with reference to the illustrated examples.
In the embodiment shown in the figure, the discharge valve device main body 1 according to the present invention is, as shown in FIG. 3, a circumferentially narrow grip groove 4 on the inner wall 7 of the opening 3 of the container 2 and the inside thereof. A valve fixing groove portion 6 including an enlarged groove 5 is integrally provided.
In the case of the embodiment, as shown in FIG. 4, the valve fixing groove 6 includes a device mounting member 10 that is integrally fitted to the container opening 3, and an opening inner wall member 11 that is fitted to the inside thereof. Become.

The device mounting member 10 is fitted on the inner and outer peripheries of the container opening 3 with fitting portions 8 and 9, and has an attachment opening frame portion 12 in an inverted L-shaped cross section on the upper portion, and a substantially deformed H-shaped cross section on the inside thereof. A shaped opening inner wall member 11 is provided to be fitted.
The opening inner wall member 11 includes an inner wall frame piece portion 13 that forms the inner wall 7 and a fitting frame piece portion 14 that fits into the mounting opening frame portion 12, and the enlarged groove 5, the gripping groove 4, and the inner wall in the fitted state. 7 is formed.

  In the embodiment, the valve main body 20 constituting the discharge valve device main body 1 includes a fixing flange portion 21 that fits into the enlarged groove 5 of the valve fixing groove portion 6, as shown in FIGS. A gripping ring portion 22 gripped by the groove 4 is provided, and a cylindrical connecting tube portion 23 is provided from the gripping ring portion 22 to the inner side B of the container opening 3 so as to be in close contact with the inner wall 7 of the opening. In addition, a substantially spherical spherical shoulder portion 24 that is recessed toward the inner side B in the connecting tube portion 23 and a container opening outer surface 25 that is continuous with the spherical shoulder portion 24 in substantially the same spherical shape are provided.

When the orifice 26 is opened at the center of the valve body 20 so as to allow the flow of fluid in a state where the connecting cylinder portion 23 is in close contact with the inner wall 7 of the opening due to a predetermined discharge pressure in the container, the predetermined discharge pressure is removed. A cross is provided to close the fluid flow.
Further, the inner side of the connecting cylinder portion 23 of the valve body 20 of the present invention has a convex mirror shape, and the central inner side 27 of the orifice 26 portion is provided in a flat shape.
Further, the inside of the orifice 26 portion of the valve body 20 of the present invention is provided in a trapezoidal cross-sectional shape.

Moreover, in the case of an Example, the discharge valve apparatus main body 1 which concerns on this invention is provided as the inner stopper or inner cover of the container 2, and the outer cover 30 is mounted | worn with the container opening part 3. FIG. The outer lid 30 includes a discharge port 31 and a mounting skirt portion 32.
