Abstract

A beverage container enabling a flavored tea to be tasted is provided when a powdered tea stored normally in a sealed container of a cap and a drinking water in a body are blended. The cap is provided on the body. When the cap is rotated, a force is imparted on a pressing rod extending from the bottom surface of the container. This force causes a mechanically weak portion in the bottom of the container to break, thus allowing a mixture to fall from the container into the drinking water.

Claims

1. A cap structure comprising a cap removably to be screwed onto a bottle mouth of a beverage container body containing a drinking water therein and a container disposed in said cap for storing a mixture, characterized in that,

said cap has a shape in which a small diameter cylindrical part is bonded to the upper side of a large diameter cylindrical part, said container that has a bottom and is cylindrical is disposed so as to project downward in order to store said mixture in said large diameter cylindrical part, a mechanically weak portion is formed at a bottom surface of said container, a pressing rod that is projected upward is disposed near said mechanically weak portion, said container is supported with a pawl portion that is formed while extending from a circumferential side near an upper end of said large diameter cylindrical part of said cap toward the center of said cap, and a locking portion that is formed while extending from a circumferential edge portion toward outside of an upper surface of said container, a pressing cap disposed at an upper surface of said pressing rod is housed in said small diameter cylindrical part and is freely threaded to a threaded part configured in an openable lid disposed while capping said small diameter cylindrical part of said cap, said cap has a projection for guiding in said small diameter cylindrical part, said projection for guiding fitted into a groove part formed on an outer circumferential side of said pressing cap to control the rotation of said pressing cap, and

when said openable lid is rotationally moved, said pressing cap is pushed downward, said pressing rod of said container is pressed down to break said mechanically weak portion of said bottom surface and open, and said mixture in said container is dropped into said drinking water.

2. The cap structure according to claim 1, wherein a lowest end part of said small diameter cylindrical part of said cap and a sided circumferential surface of said pressing cap closely contact when said mechanically weak portion of said container is broken.

3. The cap structure according to claim 1, wherein a concave bottom portion is formed on a lower surface of said pressing cap.

7. The cap structure according to claim 1 or 4, wherein a knob part is disposed at a bottom surface of said container.

4. A cap structure comprising a cap removably to be screwed onto a bottle mouth from a beverage container body containing a drinking water therein and a container disposed in said cap for storing a mixture, characterized in that,

said cap has a shape in which a small diameter cylindrical part having a threaded part on an outer circumferential side is bonded to the upper side of a large diameter cylindrical part, said container that has a bottom and is cylindrical is disposed so as to project downward in order to store said mixture in said large diameter cylindrical part, a mechanically weak portion is formed at a bottom surface of said container, a pressing rod that is projected upward is connected to said bottom surface and disposed near said mechanically weak portion, said container is supported with a pawl portion that is formed while extending from a circumferential side near an upper end of said large diameter cylindrical part of said cap toward the center of said cap, and a locking portion that is formed while extending from a circumferential edge portion toward outside of an upper surface of said container, an openable lid that is disposed at an upper surface of said pressing rod of said container, has a cylindrical shape downward and comprises a projected portion on a center of the upper side, caps said small diameter cylindrical part of said cap and is freely threaded to a threaded part, and

when said openable lid is rotationally moved, said pressing rod of said container is pressed down with said projected portion to break said mechanically weak portion of said bottom surface and open, and said mixture in said container is dropped into said drinking water.

5. The cap structure according to claim 4, wherein a tip part of said small diameter cylindrical part of said cap and a sealing member on an upper face of said openable lid closely contact when said mechanically weak portion of said container is broken.

6. The cap structure according to claim 4, wherein a concave bottom portion is formed on a lower surface of said projected portion.
