JPH0975226A - Lid of pan - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a lid that properly covers the opening of a pan, keeps drops of dew from dripping down as far as possible when the lid is opened and from overflowing during re-heating, and prevents the lower circumferential edge of a down wall from being damaged when the lid is opened and put on the pan. SOLUTION: A lid of a pan 2 has a circumferential flange 3 to be supported on a receiving flange 6 of the pan 2 and a down wall 5 to be fitted inside the opening of the pan 2, and is molded into one piece of synthetic resin, etc. An outer circumferential face 5c of the down wall 5 inclines inward and a clearance between a lower end 5a of the down wall 5 and an inner circumferential face 2a of the pan 2 is maintained so as to prevent water drops attaching on the lower end 5a of the down wall 5 from flowing round and entering a gap between the outer circumferential face 5c of the down wall 5 and the inner circumferential face 2a of the pan 2 due to the viscosity and capillarity of the water drops.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a pan lid integrally molded with a synthetic resin material or the like.

[0002]

2. Description of the Related Art A lid, which is integrally formed of heat-resistant synthetic resin or glass and is used in a convenience store or the like for an oden pot for business, usually has a structure shown in FIG. 5 or 6.

The lid shown in FIG. 5 has a horizontal flange portion B on the outer periphery of the lid main body A, and the flange portion B is supported by the projecting edge D of the pot C so as to cover the opening of the pot C. It is the one. Further, the lid of FIG. 6 is provided with a low falling wall F fitted on the inner surface of the opening of the pot C on the inner surface of the lid body E, and the lid A of FIG.
Similarly to the above, the flange G is supported by the projecting edge D of the pan C and the falling wall F is brought into close contact with the inner circumference of the opening of the pan C to cover the opening of the pan C.

[0004]

However, in the case of the lid shown in FIG. 5, it is difficult to position the lid when covering the pot, and the flange portion B of the lid cannot be properly placed on the projecting edge D of the pot C for receiving.
Further, when the receiving protruding edge D of the pot C is not a shape that horizontally projects, but is a bent type such as a circular cross-section, the hot water or juice blown directly travels along the outer wall of the pot and is a heating source such as a heater. It will cause stains and corrosion of the bottom of the pot.

Further, in the lid shown in FIG. 6, since the falling wall F and the inner peripheral wall of the pan opening are in parallel and close to each other, the vapor cooled in the upper inner wall of the lid becomes dew and travels down the inner wall of the lid. At this time, the water droplets reaching the lower end f of the falling wall enter the gap H between both walls due to its viscosity and the capillary phenomenon. This water drips when the lid is opened and pollutes the surroundings. Further, when reheated, the water droplets in the gap are pushed out of the pot from between the flange G and the receiving projecting edge D by the air in the pot which has been heated and expanded. Further, in the case of this lid, when the lid is opened and placed on a cooking table or the like, the lower end f of the entire circumference of the falling wall F comes into contact and is not only unclean, but also damaged. In particular, a lid formed of a transparent synthetic resin material is aesthetically unpleasant because stains and scratches can be seen from the outer surface of the lid.

An object of the present invention is a lid that can always cover the opening of a pan accurately, and it is possible to drip the condensed water when it is opened and to overflow the condensed water when reheating. It is to provide a pot lid that can be prevented. Another object of the present invention is to provide an improved pan lid in which, in addition to the above objects, the lower end of the entire circumference of the falling wall is not damaged.

[0007]

The present invention is characterized in that it has the following construction in order to achieve the above object.
That is, the pot lid has a flange portion on the outer periphery which is supported by the projecting edge portion of the pot, and a falling wall fitted on the inner periphery of the opening of the pot on the inner surface. It is a pot lid that is integrally formed by the above. Then, the outer peripheral surface of the falling wall is inclined inward, and the distance between the lower end of the falling wall and the inner peripheral surface of the pot is such that water droplets adhering to the lower end of the falling wall have a viscosity and a capillary phenomenon. It is kept at a distance that does not go around the gap between the outer peripheral surface and the inner peripheral surface of the pot.

In the case of a flat rectangular pot lid, for example, hemispherical small projections are provided at the four corners of the lower end surface of the falling wall. In the case of a flat-pan-shaped pot lid, the small protrusions are provided at least at three points on the lower end surface of the falling wall at equal intervals.

The lower ends of the falling walls of these pan lids may be formed in a large arc shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on illustrated embodiments. FIG. 1 is an external perspective view of a pan lid according to an embodiment of the present invention, and FIG. 2 is a sectional view of the usage state as seen from the front.

In the figure, reference numeral 1 is an opening 4 of a square oden pot 2.
The entire cover body is integrally molded with a heat-resistant transparent synthetic resin material. A flange portion 3 projects from the outer periphery of the lid body 1. The flange portion 3 is supported by a receiving projecting edge portion 6 which is horizontally formed from the open end of the oden pot 2.

A falling wall 5 is provided on the inner surface of the lid body 1. The falling wall 5 is formed by bending the lid main body hem near the boundary with the flange 3 downward into a large valley. Due to this curve, a predetermined distance d is maintained between the lower end 5a of the falling wall 5 and the inner peripheral surface 2a of the pot. As shown in FIG. 3, the interval d is such that the evaporated water in the pan is cooled near the inner surface of the top of the lid body to form dew, and the inner surface of the lid body 1a
From the lower end 5a of the falling wall 5 along the inner peripheral surface 5b of the rising wall
When the temperature reaches, the length is set such that it cannot penetrate into the gap 8 between the falling wall 5 and the inner peripheral surface 2a of the pot depending on the viscosity and the capillary phenomenon. An obtuse-angled corner 9 (see FIG. 3) formed by the upper end of the falling wall outer peripheral surface 5c and the base end of the flange inner surface is substantially formed by the pan inner peripheral surface upper end and the receiving projecting edge base end. It is supported by a right angled corner 10.

The lower end surface 5a of the falling wall 5 has a large radius R. For example, the lower end surface 5a has a diameter of 0.5 mm at four corners.
A small hemispherical small projection 7 is provided so as to project. In the figure, reference numeral 11 is a concave groove formed on the outer surface of the lid main body by the falling wall 5, and reference numeral 12 is a knob attached to the top of the lid main body.

In the pot lid of the present invention, the falling wall 5 is attached to the pot opening portion 4.
Since it is held in a proper position by fitting it in, it does not rattle or slip off in the horizontal direction. When the condensed water traveling along the inner surface 1a of the lid main body reaches the lower end 5a of the falling wall from the inner peripheral surface 5b of the falling wall, a gap 8 with the inner peripheral surface 2a of the pot 8
It does not wrap around, but drops into the pan as large water droplets. Therefore, when the lid is opened, the falling wall outer peripheral surface 5
Water drops do not fall from c. Further, since the small projections 7 are formed at the four corners on the lower end surface of the falling wall, the droplets are collected in this portion when the lid is closed, and the droplets are efficiently dropped. When reheated without opening the lid, water droplets do not penetrate into the gap 8, so the water in this portion expands and spills to the outside from the gap between the flange portion 3 and the receiving protruding edge portion 6. Don't worry.

When the lid is opened and the falling wall 5 is placed on a cooking table or the like, the small projections 7 at the four corners of the lower end surface of the falling wall come into contact with the mounting surface, and the lower end surface of the falling wall itself is described above. Since it does not rub against the placing surface, it does not get scratched or dirty, and does not deteriorate the appearance of the lid.
Further, since the lower end of the falling wall is provided with a large radius, even if dirt adheres to the inside of the concave groove 11 on the lid surface side, it can be easily removed.

FIG. 4 is a front view of a pot lid according to another embodiment of the present invention. This lid has a square flange portion 13 similarly to the above-mentioned embodiment, and the lower end surface 1 of the falling wall 15 along with this
5a is curved like a mountain on each side, and the four corners 15d are the lowest. Small projections similar to those in the above embodiment may or may not be integrally formed on these four corners 15d.

According to the lid of this embodiment, the water droplets that have reached the lower end surface 15a along the inner peripheral surface of the falling wall are guided to the four corners 15d along the inclination of the lower end surface 15a, and concentrated from there. Drop into the pan. The other points are almost the same as the above-mentioned embodiment.

The present invention can be similarly applied to a lid having a circular or irregular shape. If it is circular,
The flange portion and the falling wall have a planar circular shape, and the small protrusions projectingly provided on the lower surface of the falling wall are provided at at least three places so that the lid can be stably placed when the lid is placed. The cross-sectional shape of the small protrusion does not need to be semicircular, and various shapes such as an inverted triangle can be adopted.

[0019]

As described above, according to the present invention, the outer peripheral surface of the falling wall fitted to the inner circumference of the opening of the pan is inclined inward, and the water droplets attached to the lower end of the falling wall become the inner peripheral surface of the pan. Since it surely falls into the pan without wrapping around in the gap between it and the lid, the condensation water adhering to the outer peripheral surface of the falling wall drips when the lid is opened, or the flange and the receiving protruding edge on the pan side when reheating. It will not overflow from the gap between the parts. In addition, water drops are not retained on the receiving protruding edge portion on the pan side.

When a small projection is provided at an appropriate position on the lower end surface of the falling wall, not only can water drops around this portion be effectively dropped through the small projection, but also when the lid is placed. Since the lower end surface of the falling wall does not come into direct contact with the mounting surface, it is hygienic and does not get scratched by rubbing against the mounting surface, and the lid made with a transparent synthetic resin material looks particularly good. Can be retained for a long period of time.
