Method of fixing rim of tempered glass lid for cooking vessel and lid for cooking vessel

The present invention relates to a food cooking container used in the kitchen, and more particularly, to a rim fixing method of a cooking container lid using tempered glass and a cooking container lid using the same.

Generally, cooking vessels are classified into characteristics of materials, and there are metal containers using aluminum or stainless steel, enamels made of earthenware, glass containers made of glass, and synthetic resin containers made of plastic.

Among them, synthetic resin containers are used only for storage containers that do not require heating due to their low heat resistance, but in the case of metal containers, enamel, and glass containers, they are widely used for heating containers requiring heating due to their excellent heat resistance.

In addition, in the case of a heated cooking vessel with a lid, the container and the lid may be made of different materials.

Thus, when the container and the lid is formed of a dissimilar material, most of the container is formed of a metal and the lid is using tempered glass resistant to heat and impact so as to check the food cooking state inside the container from the outside.

Figure 1 shows the lid structure of a conventional cooking vessel made of tempered glass, briefly enumerating the manufacturing process as follows.

First, the plate glass 1 is cut to suit the size of the container, and then a hole 1a in which the lid handle 2 can be fixed in the center is drilled.

In this state, the plate glass 1 is first softened to soften the cut surface of the cut glass, and then polish the edges.

Then, the plate glass 1 is compressed in a second heat treatment state below the recrystallization temperature to be formed into a dome shape, and then cooled by blowing cold air.

Finally, the heat-treated plate glass 1 is placed on a rim (Rim) 3 in which the step 3a is formed inward, and is bent and fixed so that the upper end of the rim covers a predetermined width of the outer circumferential surface of the glass.

Figure 2 is an enlarged cross-sectional view of the main portion showing the problem of use of the lid for a conventional cooking vessel manufactured through the above process 5 is a cooking vessel in which food is contained.

In the conventional tempered glass lid having the above-described structure, when the container lid is heated to some extent during cooking of food, crackling noises are generated at these contact areas due to the difference in the expansion coefficient between the rim 3 of the stainless steel and the glass 1. Done.

During cooking, this sound gives an unpleasant feeling to the people around, and the contact portion of the rim 3 surrounding the outer circumferential surface of the glass 1 is not completely in contact with the structure as a whole, so that food and the like permeate during cooking.

This soaked food waste will not be wiped cleanly even when washed with care in dishwashing, and the residue of detergent will not be completely removed.

And if these foods are constantly put on, they become dirty enough to be seen with the naked eye and become a place where bacteria can easily grow.

That is, the conventional cooking vessel lid manufactured by the above method has been pointed out that not only can not maintain the clean state, but also gives a sense of discomfort and also the sanitary state falls.

The present invention is to solve the above problems, by maintaining the airtight between the tempered glass and the rim of the cooking vessel lid rim fixing method of the tempered glass lid for cooking vessel in consideration of cleanliness and hygiene and cooking produced through this method It is a technical problem to provide a lid for a container.

Hereinafter, preferred embodiments and operations of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 shows a process step according to the rim fixing method of the tempered glass lid of the present invention.

According to this embodiment, first, the non-toxic silicon material 13 in a gel state is injected into the step 12a of the metal rim 12. And before the silicon is solidified, the tempered glass 11 is placed on the stepped portion 12a of the rim and fixed.

Finally, the upper end of the step 12a of the rim 12 is bent and fixed to surround the outer circumferential surface of the tempered glass 11.

Forming and heat treatment process of the tempered glass 11 has the same process as the prior art described with reference to FIG.

The solidification time of the non-toxic silicone in the gel state is about 15 minutes, and when the solidified glass 11 of the solidified state of silicon is placed on the gel, it is suitable to be partially pushed upward along the outer circumferential surface of the tempered glass.

The structure of the lid for a cooking vessel of the present invention manufactured by the above-described method will be described with reference to FIG. 4.

According to this embodiment, the structure of the cooking vessel lid is fixed to the center of the tempered glass 11, the handle is fixed and the metal rim 12 is bent to surround the outer peripheral surface of the tempered glass, and also the tempered glass 11 and A nontoxic silicone material 13 is inserted between the rims 12.

Referring to the operation of the present invention having the above-described method and configuration is as follows.

Figure 5 shows an enlarged cross-sectional view of the main portion showing the state of use of the cooking lid according to the present invention, 20 shows a container in which food to be cooked.

According to the present invention, the silicon is inserted into the space between the rim 12 and the tempered glass 11 of the container lid 10, so that the glass 11 may be formed by thermal expansion of the rim 12 in which the silicon is metal even when the lid is heated. By buffering friction with), it eliminates the cause of the unpleasant noise caused by this.

In addition, the present invention maintains the airtightness of the contact portion between the rim 12 and the tempered glass 11, it is possible to prevent foreign substances such as food or detergent residues during cooking to penetrate and contaminate therebetween.

Therefore, the present invention can effectively maintain the cleanliness of the cooking vessel by effectively preventing food or foreign substances from penetrating between the glass and the rim of the cooking vessel lid and friction sound generated from the cooking vessel lid due to the difference in thermal expansion during cooking. It has the effect of preventing the growth of bacteria to provide a sanitary cooking environment.
