AI Technical Summary
Removable covers for pots cannot be attached to gas or electric stoves depending on their size and shape, leading to increased transportation costs due to their large size.
A side cover is fixed to a pot by passing the handle through a hole, attaching parts to the pot or cover, or hooking onto the pot's opening, allowing the cover to be easily attached and detached, and the flat parts can be rolled up for transportation.
The solution enables secure attachment of the cover regardless of stove shape, improves thermal efficiency, and reduces transportation costs by making the cover compact.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a technology for a removable cover that is attached to a pot such as a cylindrical pot used for cooking, etc., to create an air layer around the pot and on the lid to block the outside air and absorb as much heat as possible from a gas or electric stove or to prevent heat from escaping from the heated pot. [Background technology]
[0002] There is a method for fixing a removable cover that encloses a pot such as a stockpot used in ramen shops on a gas or electric stove. However, there was no method for making the cover that encloses the pot and lid small enough to transport. [Prior art documents]
[0003] [Non-patent literature] [Non-patent literature] Patent 6376713 Summary of the Invention [Problem to be solved by the invention]
[0004] There were several challenges in attaching a removable cover to create an air layer around the outside of the pot to increase its thermal efficiency.
[0005] Removable side covers for gas and electric stovetops cannot be installed depending on the shape of the stovetop, and the shape of the pot also makes it impossible to attach the removable side covers.
[0006] When the side covers are used to surround the pot, the handles get in the way, so the only way to get around the handles is to make the side covers larger than necessary, or to install them lower than the handles, which makes it impossible to improve thermal efficiency.
[0007] Removable side covers and lid covers that are attached to pots and lids have to have a diameter larger than the pot, which creates a problem with transportation costs. [Means for solving the problem]
[0008] In claim 1, a hole is provided in the side cover itself through which the handle of the pot passes, and the pot and side cover are fixed together by passing the handle through the side cover, hanging the side cover from the handle, and closing both ends of the side cover. There are no specific specifications for the size of the side cover or its height from the handle.
[0009] In claim 2, parts that come into contact with the sides of the pot are attached to the inside of the side cover, and by tightly tightening both ends of the side cover, the side cover parts bite into the sides of the pot, fixing the pot and side cover in place. The shape, material, mounting method, arrangement, number, etc. of the parts to be mounted inside the side cover are not specified.
[0010] In claim 3, a part that allows the side cover to be easily fixed is attached to the side of the pot itself in advance. The pot and the side cover are fixed by attaching the side cover to that part. The shape and number of parts to be attached to the pot are not specified. The attachment method is also not specified, such as wrapping the parts around the pot in a belt shape or welding them to the pot.
[0011] In claim 4, parts that hook onto the opening of the pot are attached to the top of the side cover that surrounds the side of the pot. By hooking these parts onto the opening of the pot and closing both ends of the side cover, the side cover is fixed to the pot. There is no problem even if the side cover is closed from the beginning.
[0012] In claim 5, a cover is provided that is larger than the pot and encloses the sides and bottom of the pot. The bottom of the cover is mesh-like, allowing flames and heat to pass through, and can be placed on a stovetop trivet or the like. When in use, the cover is placed on a trivet or the like, and the pot is placed through the opening in the cover to enclose the pot. The shape of the bottom can be either mesh-like or hole-like.
[0013] The method of fixing these to the pot may include parts to ensure an air gap if necessary, but the parts and method are not particularly specified. Also, the amount of air flowing between the side cover and the pot may be controlled by the number and shape of the parts that ensure the air gap. Furthermore, the shape of the side cover when attached may be a cone whose diameter decreases as it goes up.
[0014] The side covers and lid covers used to improve heat efficiency end up being larger than the pot and lid. By dividing the side covers and lid covers into flat parts and parts that are fixed or that ensure an air gap, and by making them reattachable after transportation, the flat parts that make up the majority of the size can be rolled up into a small size. [Effects of the Invention]
[0015] The present invention is expected to have the following effects.
[0016] In claim 1, by using the handle of the pot to secure the side cover to the pot, it becomes possible to secure the side cover to the pot regardless of the size or shape of the gas or electric stove. Also, even if it is not secured to the handle, the side cover does not need to avoid the handle, so there is no need to go around the handle, and the cover can extend above the handle, further increasing thermal efficiency.
[0017] In claim 2, by closing both ends of the pot, the side cover itself is hooked onto the side of the pot, making it possible to fix the side cover to the pot.
[0018] In claim 3, by attaching parts for attaching the side cover to the pot in advance, it becomes possible to attach the side cover to the parts, close both ends of the side cover, and fix the side cover to the pot.
[0019] In claim 4, by fixing the side cover using the opening of the pot, it becomes possible to fix the side cover to the pot, which can be easily attached and detached, even to pots that do not have handles.
[0020] In claim 5, instead of fixing the side cover to the pot, the cover is placed on the stovetop trivet or the like in advance, and the pot is placed through the opening of the cover and placed inside the cover, making it possible to attach and detach the cover even to pots whose covers cannot be fixed.
[0021] In claim 6, the flat plate portions that account for most of the size of the side cover and the lid cover can be made smaller, so that the packaging required for transportation can be made smaller, thereby reducing transportation costs. [Brief explanation of the drawings]

[0023] The cover according to the present invention will be described in detail below with reference to the drawings.
[0024] As shown in Figures 1, 2 and 3, insert the handles of the pot 2. into the holes in the side cover 3. that were previously cut out, close both ends of the side cover, and hang the side cover to secure the pot and side cover together.
[0025] By closing both ends of the side cover 3., the side cover parts 4. attached as shown in Figure 4 are pressed against the sides of the pot 1., fixing the pot and side cover in place.
[0026] As shown in Figure 5, first attach 5. the part for the side of the pot to 1. the pot, and then secure that part to 3. the side cover.
[0027] As shown in Figure 6, 3. secure the side cover and pot by hooking the part attached to the top of the side cover onto 1. the opening of the pot.
[0028] As shown in Figure 7, 1. the cover that encloses the pot from the sides to the bottom is placed on 8. the trivet, and the pot is put in and taken out from the top of the cover. As shown in Figure 8, 7. the bottom of the pot cover is mesh-like, which transfers heat from the stove to the pot.
[0030] As shown in Figures 9, 10, 11, and 12, 4. Side cover parts and 11. Pot lid cover parts are retrofitted to 3. Side cover and 10. Pot lid cover to form an air layer and secure them. [Explanation of symbols]
