Description

[Detailed Description of the Invention] The present invention relates to a whistling keratle whose lid is prevented from lifting by itself due to steam pressure, and its construction will be described in detail as follows with reference to the accompanying drawings.

A vertical wall 4 is formed at the opening of the vessel body 3 in which the spouting tube 1 is provided with a whistle cap 2 operated by steam pressure.
A horizontal fitting stepped portion 6 is formed on the ceiling wall 5 which is continuous with the upper part of the top wall.

A folded part 8 is formed on the outer periphery of the lid 7 to be fitted into the horizontal fitting stepped part 6, and a fitting part 9 is formed in the vertical direction at the lower part of the folded part 8. The outer peripheral surface is curved so as to be pressed against the vertical wall 4.

In the figure, 10 is a grip handle, and 11 is a horizontal reinforcing portion.

When this kind of whistle keratle boils water and the steam pressure rises, the whistle cap is activated and the whistle begins to sound.
At this time, if the lid was lifted and steam leaked, the whistle cap would not work or would not work properly.

In this regard, since the present invention is constructed as described above, the folded portion 8
is properly fitted into the horizontal fitting stepped portion 6, and the vertical wall 4
The outer peripheral surface of the fitting part 9 that is press-fitted into the vertical wall 4
Since the lid 7 is in close contact with the lid 7, the lid 7 will not be lifted even if the steam pressure increases.

In this case, since the horizontal reinforcement part 11 is formed at the lower end of the vertical wall 4, the vertical wall 4 becomes strong, and the vertical wall 4 does not bend or bend.
There is no denting, and the fitting part 9 can withstand external pressure and maintain a good adhesion state.

Therefore, steam leakage does not occur, and the steam pressure increases, allowing the whistle cap 2 to operate satisfactorily.

Since the press-fitted state of the fitting portion 9 is also curved, it imparts some elasticity, so a good press-fitting can be expected, and it will not come off unless an external force is applied to the lid 7.

Therefore, when replenishing water into the container body 3, the lid 7 must be pulled up strongly, but since the operation is simple, there is no problem in using the container.

Since the structure of the proposed product is simple, it is easy to manufacture, and it can be mass-produced, which has the same practical effects as being able to provide the product at a lower cost.
