Description

[Technical field]

[0001] The present invention relates to a food waste processing box having an upper and lower inner lid structure that maintains the airtightness of the base material inside the box, the heat retention of fermentation heat, durability and breathability, and is easy to attach and remove. [Background technology]

[0002] Conventional cardboard food waste disposal boxes are often the A-type case (Figure 5), the most commonly used type used for mandarin orange boxes, with the top lid half-open, making it difficult to create an airtight state. Even with the C-type case (Figure 6), which is a type that is separated into two halves, top and bottom, and has a lid that fits over the main body, it is difficult to create an airtight state because there is a gap between the top lid and the main body. Creating a state close to airtight is important because it promotes the fermentation of food waste and has an insect-repellent effect.

[0003] Furthermore, when conventional cardboard food waste disposal boxes are placed on the ground, they come into close contact with the ground, leaving no space and preventing ventilation, which means moisture accumulates at the bottom of the box, causing it to become humid and deteriorate, and the humidity of the base material inside the food waste disposal box increases, hindering fermentation. Preventing humidification and ensuring ventilation are important points. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2008-264709 A Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional cardboard food waste disposal boxes are often Type A cases (Figure 5), and it is difficult to maintain airtightness and heat retention when the top lid is half-open. In order to maintain airtightness and heat retention, it is necessary to cover the box from above with cloth or an insect-proof cover, and to purchase other items.

[0006] In addition, if the bottom of the box is placed directly on a flat surface, it will be in contact with the ground, which will result in poor ventilation and cause it to become stuffy, so it is necessary to place it on a bamboo mat or a mesh basket to create space and ensure ventilation, and this requires some extra effort in terms of purchasing other items and finding a place to place them.

[0007] Some containers use inner lids to maintain airtightness and heat retention, but once inserted they are difficult to remove, making it stressful to remove them every time, and pulling on them with too much force can cause them to break or rip. [Means for solving the problem]

[0008] The food waste disposal box has a cylindrical body 3, and an upper outer lid 1 and a lower outer lid 6, which are of the same size, are placed on top and bottom. An upper middle lid 2 is provided on the inside upper part of the body 3, and a first lower middle lid 4 and a second lower middle lid 5 of the same shape are provided on the bottom of the body 3 to form a double structure. The upper middle lid 2, the first lower middle lid 4 and the second lower middle lid 5 are formed of a top plate of the same size as the inner circumference of the body 3 and side plates that are bent up from the outer circumference of the top plate and are shaped to fit inside the body 3. The double structure of the bottom of the main body 3 is formed by placing the top plate 4a of the first lower intermediate lid 4 and the top plate 5a of the second lower intermediate lid 5 back to back, and folding the folded portion 4c of the first lower intermediate lid 4 and the folded portion 5c of the second lower intermediate lid 5 along the inner circumference of the main body 3 and fitting them into the bottom of the main body 3, and the lower intermediate lid 4 serves to support the base material inside the main body 3, and the side plate 5b of the raised portion of the lower intermediate lid 5 stands upright along the side surface 7 inside the main body, creating a space equal to the height of the side plate 5b between the lower outer lid 6 and the lower intermediate lid 4.

[0009] A pair of handles 2t are protrudingly provided at opposing positions on the outer edge of the upper inner lid 2, and the upper inner lid 2 can be folded along the inner periphery of the main body 3 at a folding portion 2c. Effect of the Invention

[0010] By taking the above-mentioned measures, the present invention achieves the following effects: The invention of claim 1 has an upper inner lid 2, a first lower inner lid 4, and a second lower inner lid 5 attached to a cardboard food waste processing box body 3, and then an upper outer lid 1 and a lower outer lid 6 are placed on top to maintain airtightness and heat retention, and the lower inner lid has a double structure to maintain durability, and the side panels 5b of the raised part of the second lower inner lid 5 act as clogs, so that even if the box is placed directly on the ground, a space is created at the bottom to ensure ventilation, preventing the inside of the food waste processing box from becoming steamy, and the food waste processing box alone simultaneously solves the conflicting conditions of heat retention and ventilation, and can maintain an appropriate humidity level.

[0011] The invention of claim 2 provides a handle 2t on the upper inner lid 2, which makes it easy to remove, shortening the time it takes to put in food waste every day and reducing the small stress caused by removing the lid without having to adjust the fitting position.
