The communication control block 44 has a relatively large area of the outer peripheral surface 441 along the first direction D21, and this structure allows the communication control block 44 in which the first cut 442 is formed from the liquid in the beverage container. When receiving the pressure of, the pressure received by the portion along the first direction D21 becomes relatively high, and the pressure received by this portion, that is, the second orthogonal to both the suction direction D11 and the first direction D21. The force in the direction of D22 acts in the direction of closing the first cut 442. Therefore, as long as only the pressure from the liquid in the beverage container acts on the communication control block 44, there is no force exceeding the force in the direction of the second direction D22, and the first cut 442 opens for the beverage. The situation where the liquid in the container leaks through the first cut 442 does not occur.

On the other hand, only when an external force is applied to the communication control block 44 to deform the first cut 442 and the first cut 442 is expanded, the accommodation space 311 and the drinking space 312 communicate with each other through the first cut 442. become.

The area of the cross section of the communication control block 44 orthogonal to the suction direction D11 is formed to be narrower than the area of the cross section orthogonal to the suction direction D11 of the approach side opening 411, so that the second direction from the liquid in the beverage container. Since the area that receives the pressure of D22 (the part along the first direction D21) is the widest, the pressure from the liquid in the beverage container that this area receives is also the highest, and the first cut 442 opens to drink. It is possible to more reliably avoid the situation where the liquid in the container leaks through the first cut 442.

Further, since the connection wall 43 is formed in a hollow substantially tapered shape, when the user applies a force to the communication control block 44 from the outside with a lip or the like to open the first cut 442, the first cut 442 is opened. The pressure difference on both sides of the cut 442 can be utilized to contribute to making it easier to drink.

Further, in the present embodiment, the partition wall 33 is elongated with the contour of the cross section orthogonal to the suction direction D11 in the length direction of the second direction D22 orthogonal to both the suction direction D11 and the first direction D21.
