JPH08252174A - Circular lid to be used for cooking pan - Google Patents

Abstract

PURPOSE: To prevent the rattling of lid and boiling over due to the internal pressure of pan, and getting scalded of hand due to the tumbling down of lid when reversed by fitting a cicular lid with a knob or weight to position the gravitational center of lid to outside its central area. CONSTITUTION: Its center of gravity is moved by changing the location of knob 2 on the conventional lid 1 from inside its central area. As an alternative, its center of gravity may be moved by fitting a weight to the conventional lid 1. The knob 2 or weight is located outside the central area of lid on its inside or outside surface. The nearer to its circumference, the lighter the required weight. By changing the position of the gravitational center of lid 1, naturally pushes up its edge of light side when water boils in the pan, and the rattling of lid 1 and boiling over are prevented by keeping it pushed up with blowing continuously. If the knob 2 is located outside its central area, a two-point support by the knob 2 and its edge of diagonal side makes the lid 1, when reversed, stable without tumbling down. Therefore, it prevents the hand from touching the hot surface of lid 1 and getting scalded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circular lid for a cooking pot. More specifically, the present invention relates to a lid that prevents spillage due to rattling of the lid and can be placed stably when inverted to prevent burns of hands due to rolling.

[0002]

2. Description of the Related Art In a conventional pot lid, a lid having a small hole in one corner is generally used to prevent spillage. "However, what was disclosed in the publication No. 63-58924 of the Japanese Utility Model No. 63-58924" is that a hole is made transparent in the lid and pressure is applied by rotating the knob when the lid rattles due to pressure on the lower surface of the knob attachment part and the knob hole Is pulled out. In addition, "Actual development 61-1
What was disclosed in the publication of No. 4925 was to equip the lid body with a contoured annular portion at the same or higher position as the uppermost portion of the knob, so that the lid body could be held stably and prevented from burning.

[0003]

In the conventional lid,
To prevent spillage due to rattling of the lid, the one with a small hole in one corner of the lid is too small to release steam pressure, it can not prevent rattling of the lid and spilling, and the larger the hole, the faster the water content. Notifying that the lid has boiled too much or that the lid rattles due to steam, and releasing the vapor pressure by rotating the knob is easy to cause spillage when rattling, and when putting it upside down in the rotated state, the inside of the lid is rotated. The structure of the picking was complicated and it took a lot of time to clean because there was a risk of burns due to the touch of water. In addition, a separate measure was taken to maintain stability when placed upside down with a spill.

However, among the conventional lids, the circumference of the lid is circular and the entire surface is uniform, or in the case of a circular lid in which each circumferential circle is uniform, the center of gravity of the lid has a center of gravity, so that the weight around the lid is small. It was even. If the pot boils when the weight around the lid is uniform, the steam tries to push up the entire lid and pushes up the lid in all directions, and the steam escapes from there to decompress and close the lid. The lid is lifted when pressed. This was repeated continuously, causing the lid to rattle and spilling.

Further, when the lid is placed upside down, the lid rotates around the knob as a fulcrum and is unstable.
I burned my hand on the surface. The main cause of boiled spill and the instability factor when putting it upside down, hand burns are problems with the position of the center of gravity of the conventional lid, just by remodeling the knob on this lid spilling due to rattling, putting it upside down It was not possible to solve the situation around the lid at the same time. Since these conventional inventions target the entire lid regardless of the shape of the lid, they cannot utilize the characteristics of the circular lid alone.

According to the present invention, by changing the structure in which the center of gravity of the conventional fornix is at the center, the characteristics of the fornix are not used to make complicated modifications to the knob, and it is not necessary to provide a hole, and the backlash of the lid is eliminated. The purpose of the present invention is to provide a cheap and simple lid for the purpose of preventing spillage due to sticking and allowing stable placement when turned upside down and preventing burns of the hand due to rolling of the lid.

[0007]

According to the pot lid of the present invention, in the circular lid whose entire surface is even or whose circumference is even,
Normally, the center of gravity of the lid has a center of gravity, and moving this center of gravity gives a lid with a structure in which one side is heavy and the other side is light,
The above-mentioned object was able to be achieved.

[0008]

[Operation] When the pot lid with the above structure is used, the pressure increases as the pot boils, and steam tries to push up the entire lid, but at this time, the steam always tries to escape from the light side to the heavy side. With the side edge as the fulcrum, the lid edge on the opposite side is naturally pushed up, and the pushed state is maintained until the pressure drops, allowing steam to escape. The lid at this time acts as an automatic opening / closing device that opens wide when the pressure is high and opens small when the pressure drops.

[0009]

Embodiments of the present invention will now be described with reference to the drawings. In the embodiment shown in FIG. 1, the mounting position of the knob (2) on the lid (1) of the rice paddle can be changed from the center of the main body. This is the lid whose center of gravity has moved. The mounting position of the knob is on the outer surface other than the center.

The embodiment shown in FIG. 3 is a lid in which the center of gravity is moved by a knob (4) in which the knob attachment portion is elongated toward the center of the lid (1) and the knob portion is formed outside the center. .

In the embodiment shown in FIG. 5, a weight (5) is attached to the conventional lid (1) and the center of gravity is moved. The minimum weight is the weight that can keep the edge of the side to which the weight is attached grounded when the lid is placed upside down. One or more weights may be used if the center of gravity of the lid changes, but it is symmetrical. Do not install in position. The weights are attached on the inner and outer surfaces other than the center, but the closer the edge is to the circle, the smaller the weight.

[0012]

Since the present invention is configured as described above, it has the following effects.

By changing the position of the center of gravity of the lid, when the pot is boiled, the steam naturally pushes up the edge of the light side of the lid, and the steam is continuously released to keep the lid pushed up to prevent rattling of the lid. Prevent spillage.

In the case of a structure in which the knob is located outside the center, the knob is supported at two points, the edge on the diagonal side and the lid does not roll when placed upside down, and the surface of the hot lid is stable. Prevents burns from being touched.

Further, in the case where the weight is attached to one side, the edge of the attached side is lowered so that it is supported at two points such as the knob, and when the lid is placed upside down, it is stable and does not roll. When placing the lid, it is easy to take when holding the placed lid, the surface of the hot lid is kept from touching the hands, and burns are prevented.

Also, in the case where the knob attaching portion is large and has an integral structure, the same effect can be obtained by replacing the knob of the conventional pan lid, so that the lid in use can be reused.

Further, since the steam escapes naturally, it is not necessary to make steam holes in the lid, and the manufacturing process can be omitted.

Also, unless the pressure rises to the point where it boils and lifts the lid, steam will not escape, and since there is no hole, it will be difficult to cool the inside of the pan even if the fire is stopped.
