And a plug body 3 and a valve member 4.

The container body 2 can be a bottle type made of synthetic resin, glass, or the like, and can be one having a stopper ridge or a screw thread provided around the mouth and neck portion for locking a spout.
The container body 2 in the illustrated example has the mouth and neck 7 standing upright from the body 5 via the shoulder 6, and the body 5 is configured to be elastically squeezable. A thread is provided around. In addition, when using a container body whose body cannot be elastically squeezed, the stored liquid is sucked by a straw described later.

The plug body 3 is formed of a synthetic resin or the like, and has a top wall 9 extending inward from an upper end edge of a mounting cylinder 8 fitted to the outer periphery of the mouth and neck portion 7 and a central portion of the top wall. The drinking nozzle 10 is erected upward with its base end opened. The stopper main body 3 is not limited to one having a thread provided around the inner surface of the mounting cylinder 8 and screwed around the outer periphery of the neck of the container body as shown in the illustrated example. May be fitted over a ridge provided on the outer peripheral surface of the mouth and neck of the container body.

Further, a seal cylinder 11 vertically extending downward from the inner peripheral edge of the top wall 9 is closely fitted to the inner periphery of the mouth and neck portion 7 to prevent leakage of liquid from this portion. As a means for preventing the liquid from leaking out of this portion, it is also possible to adopt a method other than the illustrated example, for example, a method in which the top wall 9 is pressed against the upper surface of the mouth and neck portion 7 or a method in which the top wall 9 and the mouth and neck portion 7 are pressed. And a method of forming a fitting projection on the inner peripheral surface of the mounting cylinder so as to closely fit with the outer peripheral surface of the mouth and neck.

The drinking nozzle 10 is for drinking the stored liquid in addition to the portion thereof, and therefore, a diameter suitable for the drinking nozzle is selected. In the illustrated example, the drinking nozzle 10 has a lower portion formed on the large diameter portion 10a and an upper portion formed on the small diameter portion 10b, and locks a later-described top plate of the valve member 4 from the upper end edge downward through the top plate 12. A locking cylinder 13 is vertically provided.

The valve member 4 is formed of a soft and highly elastic material such as an elastomer, and the peripheral portion of the top plate 15 is fitted on the inner peripheral surface of the drinking nozzle 10 above the outside air introducing hole 14 formed in the drinking nozzle 10. Along with fixing and fixing, a slit 16 is formed in the top plate 12, and a lower end edge of an annular valve plate 17 vertically suspended from the peripheral portion of the top plate 12 with a gap from the inner surface of the drinking nozzle 10 in the nozzle below the outside air introduction hole 14. It is configured by being pressed against the peripheral surface.

The shape of the slit 16 can be variously selected as long as it can be opened by hydraulic pressure when the container body 5 is squeezed, or as long as a straw can be inserted from above. A cruciform in plan view as shown in FIG. However, the present invention is not limited to this.
It may be shaped or provided with five or more cuts radially.

As shown in FIG. 2, the valve member 4 in the illustrated example has a flange 18 protruding from the peripheral edge of the dome-shaped top plate 15 and extends downward from the lower surface of the peripheral edge of the top plate 15 so as to extend outward. An annular valve plate 17 which is inclined downward is extended. A flange 18 is fitted and fixed in an annular concave portion 19 provided at the upper end of the inner peripheral surface of the large diameter portion 10a of the drinking nozzle 10, and the lower edge of the annular valve plate 17 is fixed to the inner periphery of the drinking nozzle 10 below the outside air introduction hole 14. It is attached by pressing against the surface. Also, the large diameter portion of the drinking nozzle 10
10a Cap 20 with the lower part of the surrounding wall detachably fitted to the outer periphery
Is provided. Note that the cap 20 may be any as long as it covers the drinking nozzle 10 to prevent dust or the like from adhering to the nozzle.

An example of using the beverage container 1 configured as described above will be described. If the cap 20 is removed from the state shown in FIG. 1, the drinking nozzle 10 is added, and the body 5 is squeezed while tilting the container. The slit 16 is opened by the liquid pressure, and the liquid in the container can be sucked through the locking cylinder 13.
At this time, the configuration is such that the presence of the locking cylinder 13 prevents inconvenience such as the top plate 15 in the slit portion being unnecessarily turned up. When the squeezing of the body part 5 is released, the slit 16 closes, so that the liquid once flowing above the dome-shaped top wall 9 does not return to the inside of the container. Further, since the inside of the body portion 5 becomes negative pressure due to the elastic restoring force of the container body, the outside air is introduced into the container body by opening the annular valve plate 17 through the outside air introduction hole 14.

In the beverage container of the present invention, as shown in FIG. 3, the stored liquid can be sucked using a straw 21. In this case, the straw 21 is pushed in from the upper end opening of the drinking nozzle 10, and the slit 16 is pushed open by the straw 21 to be inserted into the container and sucked. In this case, a container body whose body cannot be squeezed can be used, and in that case, outside air is sequentially introduced by opening the annular valve plate 17 to the upper part of the container body which is negatively pressured with the suction of the liquid. .
