As shown in FIG. 2, the holding portion 44 is fitted with a dowel 41 b of the air hole 41 from the upper end opening thereof to seal a portion other than the valve body.

The beverage container 10 of the present embodiment is configured as described above, and can exhibit the following effects.
The adapter 20 attached to and detached from the container body 11 is provided with a hood 21. The hood 21 is closed from the open state in FIG. 1 to the closed state in FIG. 2 or vice versa. The opening operation from the state to the opening state of FIG. 1 can be performed.

As shown in FIG. 1, when the hood 21 is open, the tip portion 26 of the straw drinking mouth 24 is exposed in an upright state from the adapter 20, and the user (not shown) By adding and sucking, the beverage contained in the container body 11 can be drunk.
When the hood 21 is closed as shown in FIG. 2, the tip end portion 26 of the straw drinking mouth hits the inside of the hood 21. Specifically, the tip of the tip 26 comes into contact with the inner wall surface of the hood 21 on the engagement claw 43 side, and the folding wall 20a of the hood 21 hits the side surface of the tip 26 and forcibly pushes it down. Bend. When the distal end portion is bent and crushed and the hood 21 is completely closed, the distal end portion 26 is accommodated in a bent state. At this time, a portion opposite to the portion where the folding wall 20 a on the outer surface of the tip end portion 26 of the straw drinking hole 24 is in contact with the vent hole 41. That is, the front end of the folding wall 20a and the outer surface of the vent hole 41 are formed at positions facing each other when the hood 21 is closed. Thereby, in the state which closed the food | hood 21, since the vent hole 41 is sealed completely, the liquid in the container main body 11 does not leak outside.

  Here, as described with reference to FIG. 2, the vent hole 41 is opened at a substantially central portion of the top surface of the raised portion 41 a slightly protruding upward from the upper end surface 27. Since the outer surface of the tip end portion 26 of the straw drinking mouth 24 hits while being crushed, it is configured to be suitably sealed, so that it can be reliably sealed. In addition, since the valve element 28 is formed at the opposite end of the vent hole 41, leakage from the vent hole 41 is prevented.

Further, as shown in FIG. 1, when the hood 21 is opened for drinking or when not sucked, the vent hole 41 opened in the upper end surface 27 is in its interior when it is ready for drinking. 2 includes the valve body 28 described with reference to FIGS. 2 and 3.
As a result, even in this state, the valve body 28 does not open unless the pressure in the container body 11 is lowered. Therefore, even if the beverage container 10 is tilted in this state, the internal beverage is not easily spilled. . Moreover, for example, even when hot water is added and agitated to increase the pressure in the container main body 11, the pressure is released from the valve body 28, and it is not inadvertently ejected.

In this embodiment, the valve body 28 described above is provided integrally with an extension of the seat plate portion 25 of the straw drinking mouth (member) 24 as described with reference to FIG. Therefore, as shown in FIG. 3, the mouthpiece member 51 has a certain size, and even if it is disassembled into parts during cleaning or the like, it is too small to be lost or too difficult to handle. It is convenient and easy to handle.
As described above, according to the present embodiment, when drinking using the straw drinking mouth 24, it is easy to suck, and even if tilted or tilted, the liquid does not easily leak, and the parts can be handled easily during cleaning. The drink container 10 made can be provided.

FIG. 4 shows a modification, which is an example in which a valve body of a vent hole is provided in a member different from the above.
That is, instead of forming the valve body integrally with the drinking port (member), the packing 61-1 is shown in the case where the valve body is provided on the packing member 61 described in FIG.
The packing 61-1 is formed of an elastic body such as silicone or elastomer as a flexible and elastic material, and includes a ring-shaped basic form having a diameter substantially coincident with the opening of the container body 11. .

  Moreover, the extension part 62 which extended the ring inner side of the packing 61-1 in the mountain shape toward inward is provided. That is, a portion extended in one direction according to the distance from the packing 61-1 to the vent hole 41 is formed, and a cylindrical holding portion 63 extending downward from the lower surface of the extension portion 62 is formed. A valve body 64 is formed at the lower end. That is, the same structure as the valve body 28 provided integrally with the straw drinking mouth 24 described in FIG. 2 and the holding portion 44 around the valve body 28 is formed inside the packing 61-1. Therefore, the dowel 41b on the adapter 20 side is also inserted into the holding portion 63 of the packing 61-1 as described with reference to FIG. 2, and the packing 61-1 itself is mounted in the receiving recess 46 provided on the inner surface of the adapter 20. By doing so, the appropriate function mentioned above can be demonstrated as a valve body in the state hold | maintained at the adapter.

  As a result, as described with reference to FIG. 4, the valve body 64 is formed by extending a part of the ring-shaped portion of the packing 61-1 and integrally therewith. Therefore, as shown in FIG. 4, the packing 61-1 has a certain size, and even when disassembled into parts during cleaning or the like, it is too small to lose or become so small that it is difficult to handle. This is convenient and easy to handle.

Furthermore, the adapter 20 of the beverage container of the present invention can be attached to the vicinity of the opening of a narrow mouth bottle (not shown) by reducing its diameter, for example, and used as a lid with a drinking mouth.
That is, since the adapter 20 is provided with the hood 21, it can function as a lid with a mouthpiece by attaching it to a bottle or a general-purpose liquid container. In this case, a general-purpose or ready-made bottle and the lid with a drinking mouth are integrated to constitute the beverage container of the present invention.
The above-described narrow-bottle is, for example, a beverage container shown in FIG. 1 of Patent Document 2, such as a beverage bottle in which a beverage or the like is stored in advance.

  The present invention is not limited to the above-described embodiments. For example, it is not attached by the dowel 41b which is the convex part of the vent hole 41 and the holding parts 44 and 63 which are the concave parts of the valve body 28, but the relationship between the concaves and convexes is reversed or another engaging part is formed to engage. You may comprise so that it may carry out. In addition, the tip portion 26 is not bent by the rotation about the support shaft 22 eccentric to one side of the hood 21, but the hood 21 is moved relatively in a sliding manner along the top surface of the adapter 20. The hood portion may be opened and closed. Each configuration in each of the above-described embodiments may be implemented under a combination of different configurations, if necessary, by omitting a part thereof or replacing other configurations.
