Beverage containers can be easily disassembled in this way, so that they can be sufficiently cleaned and always used hygienically.

7 and 8 show another embodiment of the cap for a beverage container according to the present invention.

A slider 71a is provided between the outer shell 176 and the inner shell 150 so as to be slidable. In this embodiment, the slider is a flat slide type. When the slider 71a is advanced, the pressing portion 72a is provided. ) Pressurizes the side portion of the beverage suction tube 60, the bent point member (55a) is bent from the starting point and the internal flow path (60a) is closed.

The valve seat 21 is attached to the inner shell, and valve bodies 22 and 23 protruding from the back of the slider are provided in two places.

As shown in FIG. 8B, the beverage suction tube is closed because the valve body 22 is in contact with the valve seat 21 while the slider 71a is advanced to close the beverage suction tube. When the slider starts to retreat by operating the handle 75a in the closed state, the valve body 22 is dropped from the valve seat 21, and the inside and the outside of the container communicate with each other through the vent hole, and the elevated pressure inside is discharged to the outside. .

After that, the pressing portion 72a is separated from the beverage suction tube, and the beverage suction tube is extended to drink the beverage.

As shown in Fig. 8A, the valve body 23 is in contact with the valve seat even when the slider is retracted and the beverage suction tube is extended.

9 shows an embodiment of a cap for a beverage container of a rotating slide type.

9A shows an external perspective view, and FIG. 9B shows a plan view.

The shield member 250 is provided with a valve seat 121 having a vent hole, and the slider 171 is provided with a valve body 123 and two valve bodies 122a and 122b on the left and right sides thereof. .

The valve device is constituted by a slider 171 that rotates with the bending point member 155 of the beverage suction tube 60.

When the beverage suction tube 60 is in an extended state, the central valve body 123 abuts against the valve seat 121 so that the beverage suction tube 60 bends whether the slider 171 is turned to the right or to the left. 9 (b), the valve body 122a abuts against the valve seat 121 when the slider 171 rotates in the right rotation direction, and the valve body 122b when the slider 171 rotates in the left rotation direction. ) Comes into contact with the valve seat 121.

Therefore, in the state where the beverage suction tube 60 is bent by closing the valve device, any one of the valve bodies 122a and 122b of the vent hole opening and closing device abuts the valve seat 121 to block the vent hole. Therefore, if a warm liquid beverage is contained in the container, the internal air pressure increases.

When the slider 171 starts to rotate, since the valve body 122a or 122b is separated from the valve seat 121 and the internal pressure is discharged to the outside from the vent hole, the internal pressure is reduced when the beverage suction tube 60 is extended. Even if the end of the straw is in the beverage, the beverage is not ejected by the internal pressure from the beverage suction port of the beverage suction tube.

In addition, since the valve body 123 is in contact with the valve seat 121 in the state where the beverage suction tube is extended, the beverage does not leak from the vent hole when the beverage is drinked.

According to the present invention, a flexible beverage tube such as a tube made of silicone resin is provided in a cap for a beverage container, and the air vent of the ventilation hole communicating with the opening / closing valve device and its inside and outside of the container according to the bending and extension of the beverage suction tube. By installing a hole opening / closing device, when a warm liquid beverage is accommodated in the beverage container, the internally increased pressure can be discharged to the outside through the vent hole, thereby effectively preventing the liquid beverage from suddenly ejecting from the beverage inlet of the beverage suction tube. do.

By interlocking the vent hole opening and closing device by the opening and closing operation of the valve device, it is possible to reliably remove the internal pressure increase by only opening the valve device.

When the valve device is composed of a slidable slider capable of positioning the valve device and a bending point member which is in contact with the side of the beverage suction tube, the inner flow path of the beverage suction tube can be opened and closed by sliding the slider.

Further, by providing a valve body protruding from the slider and providing a valve seat having a vent hole in which the inside and the outside of the container communicate with the shielding member, the valve device and the opening and closing device of the vent hole can be interlocked.

When the slider is provided with at least two valve bodies which come in contact with the valve seat with the slider closed and open, the slider is in an open state, that is, a drink is available, and the slider is closed, i.e. In this case, the ventilation holes are blocked in both the state of not drinking, and the ventilation holes are in communication with each other during the opening and closing operation of the slider.

Therefore, in the state before the slider starts to open and the beverage suction tube is extended, the vent hole is communicated to remove the increased internal pressure. After that, the beverage suction tube is extended and the internal flow path is communicated. The liquid beverage is not suddenly ejected from the beverage inlet.

In addition, since the valve body is in contact with the valve seat even when the slider is completely opened and the beverage suction tube is extended, the beverage does not suddenly leak from the vent hole during the drink.
