Even in this case, the two air holes can communicate with each other through the groove 58.

(iii) Valve body FIG. 9 is a front view of the valve body 31, FIG. 10 is a plan view of the valve body 31, and FIG. 11 is a cross-sectional view of the valve body 31. Hereinafter, the details of the valve body 31 will be described based on FIGS. 1, 9, and 10.
The valve body 31 is made of thick silicone having flexibility, and has a flat funnel shape. The height of the valve body 31 is slightly longer than the length of the shaft portion of the hanging portion 59 of the valve seat 29 (the length from the bottom portion 51 to the upper surface portion 61a of the bulging portion 61) from the bottom surface to the upper surface of the bulging portion. Only set to be higher.
A hole 67 having a diameter substantially equal to the outer diameter of the hanging portion 59 of the valve seat is provided in the central portion of the valve body 31. A protruding portion 69 protruding upward is formed on the inner peripheral edge of the hole 67. A flat portion 71 is formed at the upper end portion of the valve body 31. A thin ring-shaped wall that extends outwardly at a position slightly below the upper end of the outer periphery of the valve body 31, bends upward from the middle, and has a tip extending slightly above the flat portion 71. 73 is formed. Therefore, the ring-shaped groove 75 is formed in the valve body outer peripheral portion by the outer peripheral portion of the valve body 31 and the ring-shaped wall 73.

As shown in FIG. 1, the valve body 31 formed as described above is attached to the valve seat 29 by inserting a hole 67 into the hanging portion 59 of the valve seat 29. In a state in which the hanging portion 59 of the valve seat 29 is inserted into the hole 67 of the valve body 31, the peripheral portion of the hole 67 contacts the upper surface of the bulging portion 61 of the hanging portion 59, and the flat portion 71 at the upper end of the valve body 31 is The valve seat 29 is in contact with the bottom surface of the bottom. At this time, since the length from the bottom surface of the hanging portion 59 to the upper surface portion 61a of the bulging portion 61 is set to be shorter than the height in the normal state of the valve body 31, the valve body 31 is attached to the valve seat. The hole peripheral portion of the valve body 31 is pressed against the upper surface of the bulging portion of the valve seat 29 by the elasticity of the valve body 31, and the upper end of the valve body 31 is pressed against the lower surface of the bottom of the valve seat 29.

At this time, the vent hole 57 formed in the flange portion 55 of the valve seat 29 is located inside the ring-shaped wall 73, that is, above the ring-shaped groove portion 75. Since the diameter of the hole 67 is formed substantially the same as the outer diameter of the hanging part 59, the relative position between the valve body 31 and the valve seat 29 is not shifted, and the vent hole 57 is always located above the ring-shaped groove 75. be able to.

<Cover body>
As shown in FIG. 1, the cover body 15 has a cap shape with an open lower end, and is attached so as to cover the entire mouthpiece so as to cover the attachment member 13 from the outside. The cover body 15 is held by the lower end edge of the cover body 15 engaging the lower end of the mounting member 13.

Next, the operation of the present embodiment configured as described above will be described. FIG. 12 and FIG. 13 are explanatory diagrams of the operation, FIG. 12 shows a state before drinking, and FIG. 13 shows the state of the valve body during drinking with a broken line.
In the state before drinking, as shown in FIG. 12, the hole peripheral edge part of the valve body 31 is contact | abutted to the upper surface part 61a of the bulging part 61, and the drink is prevented from going to the valve seat side. Therefore, in this state, the beverage on the container body side does not go to the mouthpiece side, so that, for example, even if an infant is in the middle of sucking and drops the beverage container, the beverage does not run down.
Further, the vent hole 45 provided in the valve seat 29 is covered with a ring-shaped wall 73, and the beverage on the container body side does not leak from here.

  Next, when sucking and drinking from the mouthpiece 27, the suction side becomes negative pressure, and a differential pressure is generated between the mouth side and the container body side. As shown by the broken line 13, it moves up. When the central portion of the valve body 31 moves upward, a gap is formed between the valve body 31 and the upper surface portion 61a of the bulging portion 61, and the beverage passes through this gap and the cross gap of the hanging portion 59, and the valve seat 29 It passes through the opening 65 and moves to the mouthpiece side. The beverage that has moved to the mouthpiece side is sucked through the hole 99.

By sucking and drinking from the mouthpiece 27, the mouthpiece side communicates with the container body side, so that the container body side becomes negative pressure. If it remains in this state, the container body side and the mouth side become the same pressure, the valve body 31 returns to the state before sucking, and continuous sucking cannot be performed.
However, in the present embodiment, when drinking is performed, the upper end of the ring-shaped wall 73 formed on the outer peripheral portion of the valve body 31 with the upward movement of the central portion of the valve body 31 is the bottom lower surface of the valve seat 29. The air hole 57 is thereby opened. When the vent hole 57 is opened, air is introduced to the container body side, and the negative pressure on the container body side is eliminated, so that continuous drinking is possible.
Thus, smooth drinking is realized by the cooperation of the valve structure of both the central part and the peripheral part of the valve body 31.
Moreover, the two valve structures are realized by the single body of the valve body 31, and the structure is simple.

The vent hole 57 is opened at the time of drinking, but the vent hole 57 is provided on the side opposite to the mouthpiece portion 35. 57 is located on the upper side, and the beverage does not leak from the vent hole.
Further, since the vent hole 57 is located at the position of the ring-shaped groove 75 formed in the valve body 31, if a gap is generated at some portion on the circumference between the ring-shaped wall 73 and the valve body 31, the container The main body side and the vent hole communicate with each other. This point will be specifically described. For example, assuming that both drinks are about half of the drink, in this case, the drink is usually taken with the container body facing horizontally. At this time, the beverage is in the lower half of the valve body 31, the lower half of the central portion of the valve body 31 moves upward, and the upper end of the ring-shaped wall 73 on the lower half side also moves away from the bottom lower surface of the valve seat 29. do. Even in such a case, the vent hole 57 and the portion where the upper end of the ring-shaped wall 73 is separated communicate with each other via the ring-shaped groove 75, and air is introduced to the container body side.

As described above, in the present embodiment, the beverage supply valve structure 11 is provided in the opening 3 of the container body 5, and when the container body 5 is sucked from the mouthpiece 27 of the beverage supply valve structure 11, Since the beverage is supplied to the mouthpiece 27 side and air is supplied to the container body 5 side, continuous and smooth drinking can be performed. Moreover, since the beverage on the container body 5 side does not flow toward the mouthpiece 27 when not drinking, the beverage on the container body side does not flow out of the mouthpiece 27 even if the container is tilted.
In the present embodiment, the passage of the beverage is controlled at the central portion of the valve body 31, and the opening and closing of the vent hole 57 is controlled by the ring-shaped wall 73 of the outer peripheral portion of the valve body 31. Since the first and second valve structures of the invention are realized, the entire configuration can be simplified.

  In the mouthpiece 27 in the above embodiment, the example in which the position of the vent hole 45 is provided on the opposite side in the circumferential direction of the position where the mouthpiece portion 35 is provided, that is, at a position of 180 degrees, is shown. The present invention is not limited to this, and if the position of the air vent 45 and the position of the mouthpiece 35 are separated by 90 degrees or more in the circumferential direction, although it depends on the amount of the beverage, the leakage of the beverage at the time of drinking is usually performed. The effect of preventing can be sufficiently obtained.
