Description

Technical Field

[0001] The present invention relates to a food waste treatment box that maintains the airtightness, heat retention of fermentation heat, durability, and breathability of the base material inside the box, and forms an upper middle lid and a lower middle lid structure that are easy to attach and detach.

Background Art

[0002] Conventional cardboard food waste treatment boxes often use the most commonly used Type A cases such as those used for orange boxes, as shown in Fig. 5. It is difficult to create a sealed state with the upper lid half-open. Also, in the case of the Type C case shown in Fig. 6, which is divided into two parts, the upper and lower parts, with a lid covering the main body, a gap is formed between the upper lid and the main body, making it difficult to achieve a sealed state. Creating a state close to airtightness is an important point because it promotes the fermentation of food waste and has an insect-proof effect.

[0003] Moreover, conventional cardboard food waste treatment boxes, when placed on the ground, are in close contact with the ground, leaving no space for ensuring breathability. As a result, moisture accumulates at the bottom of the box, causing it to become musty and the bottom of the box to deteriorate easily. This increases the humidity of the base material inside the food waste treatment box, hindering fermentation. Preventing mustiness and ensuring breathability are important points.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Conventional cardboard food waste treatment boxes often use Type A cases as shown in Fig. 5. It is difficult to maintain airtightness and heat retention with the upper lid in a semi-open state. To maintain airtightness and heat retention, it is necessary to cover it from above with a cloth or an insect-proof cover, etc., and purchase other items.

[0006] In addition, if the bottom of the box is placed directly on a flat surface, it will stick to the ground, resulting in poor ventilation and causing stuffiness. Therefore, it is necessary to place it on a bamboo mat or wire basket to create space and ensure ventilation. Additionally, some extra effort is required to devise the purchase and placement of other items.

[0007] Some items use an inner lid to maintain airtightness and heat preservation. However, it is difficult to insert and remove the inner lid, causing stress each time it is removed. Pulling it forcefully may cause damage or breakage.

Means for Solving the Problem

[0008] The box for raw garbage disposal has a cylindrical main body 3, and is in a form where upper outer lid 1 and lower outer lid 6 with the same dimensions up and down cover from above and below. An upper inner lid 2 is provided at the upper inner part of the main body 3, and a first lower inner lid 4 and a second lower inner lid 5 are provided at the bottom of the main body 3 in the same shape to form a double structure. The upper inner lid 2, the first lower inner lid 4, and the second lower inner lid 5 are formed by a top plate having the same dimensions as the inner circumference of the main body 3 and side plates that are bent and raised from the outer circumference of the top plate, and are shaped to fit inside the main body 3. The double structure at the bottom of the main body 3 has the top plate 4a of the first lower inner lid 4 and the top plate 5a of the second lower inner lid 5 back to back, and the bent part 4c of the first lower inner lid 4 and the bent part 5c of the second lower inner lid 5 are bent along the inner circumference of the main body 3 and fitted into the bottom of the main body 3. The lower inner lid 4 serves to receive the base material inside the main body 3, and the side plate 5b of the raised part of the lower inner lid 5 stands in contact along the side surface 7 inside the main body, creating a space with the height of the side plate 5b between it and the lower outer lid 6.

[0009] A pair of handles 2t are protruding at the opposing positions of the outer edge of the upper inner lid 2, and it has a structure that can be bent at the bent part 2c of the upper inner lid 2 along the inner circumference of the main body 3.

Effects of the Invention

[0010] By taking the above measures, the present invention has the following effects. The invention according to claim 1 attaches an upper middle lid 2, a first lower middle lid 4, and a second lower middle lid 5 to the cardboard domestic waste treatment box body 3, and further covers the upper outer lid 1 and the lower outer lid 6 as lids, so that airtightness and heat preservation can be maintained. Furthermore, by making the lower middle lid a double structure, durability is also maintained. Since the side plate 5b of the rising part of the second lower middle lid 5 serves as a clog, even when placed directly on the ground, a space is formed at the bottom to ensure ventilation, preventing the stuffiness inside the domestic waste treatment box, simultaneously solving the contradictory states of heat preservation and ventilation with a single domestic waste treatment box, and being able to maintain an appropriate humidity.

[0011] The invention according to claim 2 provides a handle 2t on the upper middle lid 2, making it easy to remove. Along with shortening the daily domestic waste input time, since it can be removed without aligning the fitting position, it can reduce every small stress.

Embodiments for Carrying Out the Invention

[0013] FIG. 1 is a perspective view of an entire cardboard box for treating food waste according to an embodiment of the present invention. This food waste treatment box is an octagonal prism with a design that balances strength and ease of mixing. The main body 3 of the cylindrical box is composed of an upper outer lid 1 and a lower outer lid 6, which are overlapping lids with the same dimensions in the vertical direction. Inside, an upper middle lid 2 with a handle is provided at the upper part, and the bottom is a structure in which a first lower middle lid 4 and a second lower middle lid 5 with the same shape are double-fitted. These three middle lids are formed by top plates 2a, 4a, 5a having the same dimensions as the inner circumference of the main body 3 and side plates 2b, 4b, 5b that are bent and raised from the outer circumference of the top plates. They share a bendable side at their boundary, and when they are raised at 90 degrees at the bending parts 2c, 4c, 5c, they can be fitted along the inner side surface 7 of the main body, resulting in a structure that can handle airtightness and heat retention.

[0014] Furthermore, a pair of handles 2t are protruded at opposite positions on the outer edge of the upper middle lid 2, and a pair of handles 2t are similarly protruded at a position rotated 90 degrees from the opposite position, so that it can be removed from any position. When the top plate 4a of the first lower middle lid 4 and the top plate 5a of the second lower middle lid 5 are placed back to back, and the side plates 4b of the first lower middle lid 4 and 5b of the second lower middle lid 5 that are bent and raised from the outer circumference of the top plates are fitted along the inner side surface 7 of the main body to the bottom, the lower middle lid becomes a double structure and can handle airtightness, heat retention, and durability.

[0015] Figure 2 is a longitudinal sectional view showing a state in which the base material 8 for decomposing and fermenting food waste is placed in the main body 3 and food waste can be put in, in the state of using the cardboard food waste processing box according to the embodiment of the present invention. The upper middle lid 2 bends the side plate 2b at the bending portion 2c by 90 degrees. The side plate 2b fits tightly along the inner side surface 7 of the main body when it is inserted into the upper part. The side plate 4b of the first lower middle lid 4 and the side plate 5b of the second lower middle lid 5 also bend the bending portion 4c of the first lower middle lid 4 and the bending portion 5c of the second lower middle lid 5 by 90 degrees. Then, the top plate 4a of the first lower middle lid 4 and the top plate 5a of the second lower middle lid 5 are back to back, and the outer surfaces of the side plates 4b and 5b fit tightly along the inner side surface 7 of the main body when they are inserted into the bottom, forming a double structure. When the upper outer lid 1 and the lower outer lid 6 are overlapped vertically, it can cope with heat preservation and durability. Further, the side plate 5b of the second lower middle lid 5 is in perpendicular contact with the bottom surface of the lower outer lid 6, so that the height of the side plate 5b serves as a clog, creating a bottom space 9 to ensure air permeability and prevent stuffiness.

[0016] Figure 3 is a development view of the upper middle lid 2 attached to the upper inner part of the main body 3 of the cardboard food waste processing box according to the present invention. The top plate 2a having the same dimensions as the inner circumference of the main body 3 is in the shape of a regular octagon plate. Rectangular side plates 2b are provided from each of the eight sides. A 45-degree cut is made between adjacent side plates 2b. When it is bent up to 90 degrees with respect to the top plate 2a at the bending portion 2c, adjacent side plates 2b are in close contact. When it is inserted along the inner side surface 7 of the main body, there is no gap, forming a configuration corresponding to airtightness. Also, a pair of handles 2t with a size of about 30 mm are protruded at opposite positions of the upper middle lid 2, and a pair of handles 2t are also protruded at opposite positions rotated 90 degrees from the handle positions, forming handles at balanced positions on the octagonal upper middle lid 2, and having a user-friendly structure that can be removed from any position. Note that the above dimensions are only examples and are not limited thereto.

[0017] FIG. 4 is a development view of a first lower middle lid 4 and a second lower middle lid 5 attached to the bottom of the main body 3 of the cardboard food waste disposal box according to the present invention. The top plates 4a of the first lower middle lid 4 and 5a of the second lower middle lid 5 having the same dimensions as the inner circumference of the main body 3 are in the shape of a regular octagonal plate, and rectangular side plates 4b of the first lower middle lid 4 and 5b of the second lower middle lid 5 are provided from each of the eight sides. A 45-degree cut is made between the adjacent side plates 4b and 5b, and when bent to 90 degrees with respect to the top plates 4a and 5a at the bent portions 4c of the first lower middle lid 4 and 5c of the second lower middle lid 5, the adjacent side plates 4b and 5b are in close contact. Further, triangular protruding pieces 5d are provided at the attachment roots of the side plates 4b and 5b on the top plates 4a and 5a, and by fitting the protruding pieces 5d along the inner corner portions 7e of the main body, there is no further gap and the structure prevents leakage of the inner base material 8.

[0018] In addition, in the above embodiment, the case where the main body 3 is in the shape of a regular octagonal cylinder and the top plates 2a of the upper middle lid 2, 4a of the first lower middle lid 4, and 5a of the second lower middle lid 5 are regular octagons has been described, but it is not limited to this. The shape of the cylinder of the main body 3 and the top plates of the respective middle lids is preferably a regular polygon with an even number, and particularly preferably a regular octagon, a regular decagon, and a regular hexagon.
