DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a teapot used for brewing tea and herbs.
BACKGROUND OF THE INVENTION
As shown in the FIG. 9, a teapot of the prior art comprises a teapot body 6 having a top-mouth 61 and lid 62 closing the top-mouth 61. A suction port 63 is excavated on the lid 62 adjacement to its periphery. The suction port 63 is spaced some distance from the center of the lid 62.
As shown in the FIG. 10, the diameter of the lid 62 is less than the inside diameter of the top-mouth 61 of the teapot body 6. Thus, the lid 62 is just mounted on the top-mouth 61.
As shown in the FIG. 11, the tea 5 often spills out from the suction port 63 when the tea 5 is poured out from the outlet 64.
Consequently, air can not be efficiently sucked from the suction port 63, hot water cannot be agitated in the teapot body 6 adequately, and the filtering holes 65 of the outlet 64 are apt to be clogged by tea leaves.
Accordingly, it is an object of the present invention to provide a teapot into which air can be efficiently sucked through a suction port to efficiently agitate tea for brewing and which can prevent clogging of filtering holes by the tea leaves.
SUMMARY OF THE INVENTION
To accomplish the foregoing objects, the present invention comprises; a teapot body having a top-mouth at the top thereof and a outlet on the side wall thereof, and a lid 2 which covers said top-mouth, characterized in that a suction port is formed adjacent to the center of said lid, a vent hole is provided from the center toward the periphery of said lid, and said vent hole communicates with said suction port.

BEST MODE OF CARRYING OUT THE INVENTION
An embodiment of the present invention is described by referring the drawings.
Embodiment 1
As shown in FIG. 1, the pot of the present embodiment comprises a teapot body 1 and a lid 2. The teapot body 1 has a top-mouth 3 at its top, and an outlet 11 and a handle 13 on the its side wall. The lid 2 covers the top-mouth 3.
As shown in FIG. 2 and FIG. 3, the lid 2 has a knob 24 on the center thereof, in order to pick the lid 2 up. A suction port 20 is excavated adjacent to the knob 24. A vent hole 21 is provided in the bottom surface of the lid 2, which communicates with the suction port 20.
The vent hole 21 is formed by a half-tube wall 23 from the center toward the outside of the inner bottom surface 25. The vent hole 21 is connected to the suction port 20 and its inside end is blocked. The outside end of the vent hole 21 is opening as a blow-out port 22. The blow-out port 22 is adjacent to the periphery of the lid 2.
The bottom surface of the lid 2 comprises the inner bottom surface 25 and the outer bottom surface 26. The inner bottom surface 25 is formed declining from the center to the outer bottom surface 26, in the manner that the thickness of the lid 2 gradually increases. Therefore, the inner bottom surface 25 is downward curved in substance. And the outer bottom surface 26 is formed mono-thickness. The blow-out port 22 of the vent hole 21 is adjacent to the inside of the outer bottom surface 26.
As shown in FIG. 1, a stopper ring 32 is provided at the inside of the top-mouth 3, on which the lid 2 is put, and its upper surface is flattened so as to be shaped almost the same as the outer bottom surface
