Description

[Detailed description of the invention] This invention relates to a drop lid that is placed on top of boiling food in a pot.

When boiling food in a pot, a lid is used to enhance the simmering effect.

Conventional drop lids are made of wood, so they are expensive due to high material costs and laborious processing, and because they are not disposable, it takes time and effort to clean them after use, and they lack a sense of cleanliness. There is.

This idea was made to eliminate the above-mentioned drawbacks, and it is easy to manufacture, easy to use,
The purpose is to provide a drop lid that is clean, inexpensive, and disposable.

The structure of this device is to form a drop-lid main body using metal foil, and provide the drop-lid main body with a reinforcing bead portion that protrudes from the top side and a cut line that forms a knob piece that can be raised and lowered. .

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the drop lid 1 of this invention has a circular drop lid body 2 made of metal foil such as aluminum foil, an annular reinforcing bead portion 3, and a pull-out tab piece 4 in the center. A cut line 5 is provided.

As shown in FIG. 3, a rolled-up edge 6 is provided on the outer peripheral edge of the drop-lid main body 2 to improve the overall strength.

The thickness of the metal foil used for the drop lid main body 2 can be arbitrarily selected depending on the diameter etc., but the formation of the reinforcing bead 3 and the rolled edge 6 greatly increases the overall bending strength. Since the thickness is improved, the thickness can be made extremely thin. For example, in the case of a diameter of 200 mm, it is practical even if the thickness is about 0.025 mm.

As shown in FIG. 1, the reinforcing bead portion 3 has a circular shape coaxial with the drop lid main body 2, and is formed in a plurality of strips at regular intervals. Note that the shape of the lid body 2 can be selected as appropriate, and therefore the shape of the bead portion 3 may also be selected according to the shape of the lid body 2.

As shown in FIG. 3, this bead portion 3 is bent to have a cross-sectional shape projecting in a chevron shape toward the upper surface of the drop-lid main body 2. The shape of this bead portion 3 can adopt various cross-sectional shapes as long as it improves the strength of the drop lid main body 2, but if it is made into a chevron shape that protrudes toward the upper surface side as shown in the figure, steam retention will occur on the lower surface side. 7 can be formed and the boiling effect can be improved.

The cut line 5 is formed in a U-shape or a U-shape at the center of the drop-lid main body 2, and the portion surrounded by the cut line 5 forms a tab piece 4 when lifted.

In the case shown in the figure, two U-shaped cut lines 5 are provided in opposite positions on both sides of the drop lid main body 2, and the tab pieces 4 on both sides can be held at the same time. , the cut line may be provided only at one location.

The drop lid of this invention has the above structure and can be formed using metal foil such as aluminum foil, so it is easy to manufacture, easy to use, and provides a clean feeling when used.

In addition, since the bead part is reinforced, sufficient strength can be obtained even if the thickness of the metal foil is reduced, and since it requires less material and can be provided at low cost, it can also be used as a disposable product. , and the bead portion is formed to protrude toward the upper surface side, so
The bottom side becomes a flow path for steam and broth, improving the boiling effect.

Furthermore, since a cut line is provided to form a pull-out knob piece, the pot can be easily dropped into and taken out by holding the knob piece.

In addition, if you raise the knob a little and adjust the opening amount appropriately when using it, this part will vent steam and prevent the whole thing from being pushed up by the steam pressure, and the steam and broth will not flow to the top of the boiled food. Since the degree of circulation can also be adjusted, the effect of the lid can be effectively demonstrated.
