Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a food box. Background Technology

[0002] Most existing food packaging boxes have a simple structure and cannot meet the packaging needs of some special foods. For example, some foods are sensitive to humidity. If too much water accumulates inside the box, it may accelerate the spoilage of the food. The heat and moisture of some foods will evaporate over time, and the resulting water vapor will condense into water droplets after contacting the box and fall back onto the food, affecting it.

[0003] An existing invention with publication number CN111301834A discloses a novel takeaway box, including a lid and a body, wherein the lid and the body are detachably connected, and the interior of the takeaway box is provided with an adsorption layer for absorbing water vapor; at least one of the lid and / or the body has an adsorption layer installed inside. While this patent solves the problem of water vapor, water vapor releases heat when it condenses in a closed space. This process originally helps to maintain the temperature of the food. After the adsorption layer quickly absorbs water vapor, although it avoids the formation of condensation, it also leads to increased heat loss and poor heat preservation effect. Utility Model Content

[0004] The purpose of this utility model is to provide a food box to solve the technical problem of poor heat insulation in the prior art.

[0005] To solve the above problems, the food box involved in this utility model adopts the following technical solution:

[0006] This utility model provides a food box, including an inner box, an outer box, and a lid. The lid includes a lid bottom, a first annular lid wall, and a second annular lid wall. The first and second annular lid walls are coaxially arranged on the bottom of the lid bottom. The first annular lid wall is spaced out and sleeved on the outside of the second annular lid wall. The inner box is screwed to the second annular lid wall, and the outer box is screwed to the first annular lid wall. The outer box is sleeved on the outside of the inner box. A gap is left between the bottom surface of the outer box and the bottom surface of the inner box, and a gap is left between the peripheral wall of the outer box and the peripheral wall of the inner box.

[0007] Preferably, the bottom of the cover has a channel that runs through its upper and lower ends, and the channel is connected to the enclosed space of the second annular cover wall. The channel is provided with absorbent cotton and an isolation net located between the absorbent cotton and the enclosed space to isolate the enclosed space from the absorbent cotton.

[0008] Preferably, it also includes a partition plate covering the channel, the partition plate being screwed to the box cover and located on the side of the absorbent cotton away from the isolation net, the partition plate and the absorbent cotton being spaced apart, and the partition plate, the absorbent cotton and the inner wall of the channel forming a storage space.

[0009] Preferably, the bottom of the inner box has a drain mesh that communicates with the outer box.

[0010] The beneficial effects of this utility model are as follows:

[0011] The food box provided by this utility model differs from the prior art in that it includes an inner box, an outer box, and a lid.

[0015] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] This utility model provides a food box, including an inner box 1, an outer box 2, and a lid. The lid includes a lid bottom 3, a first annular lid wall 4, and a second annular lid wall 5. The first annular lid wall 4 is configured as an annular structure extending circumferentially along the edge of the lid bottom 3 and connected end to end. The first annular lid wall 4 and the lid bottom 3 are integrally formed. The first annular lid wall 4 and the second annular lid wall 5 are coaxially arranged on the bottom of the lid bottom 3. The first annular lid wall 4 is fitted onto the outside of the second annular lid wall 5, and a gap is left between the first annular lid wall 4 and the second annular lid wall 5. An internal thread is formed on the inner side of the second annular lid wall 5. An external thread corresponding to the internal thread of the second annular lid wall 5 is formed on the inner box 1. The outer diameter of the opening section of the inner box 1 is matched with the inner diameter of the second annular lid wall 5. The opening of the inner box 1 can enter the second annular cover wall 5 and be screwed to it. The inner side of the first annular cover wall 4 is provided with an internal thread, and the outer box 2 is provided with an external thread corresponding to the internal thread of the first annular cover wall 4. The outer diameter of the opening of the outer box 2 is matched with the inner diameter of the first annular cover wall 4 so that the opening of the outer box 2 can enter the first annular cover wall 4 and be screwed to it. That is, the outer box 2 is fitted on the outside of the inner box 1. Furthermore, a gap is left between the bottom surface of the outer box 2 and the bottom surface of the inner box 1, and a gap is left between the peripheral wall of the outer box 2 and the peripheral wall of the inner box 1. The inner wall of the outer box 2, the outer wall of the inner box 1, and the lid together form a heat insulation cavity for heat insulation or a water storage space for water seepage from the inner box 1 or a space for placing ice packs / heat packs.

[0018] The bottom cover 3 has a channel that runs through its upper and lower ends and is connected to the enclosed space of the second annular cover wall 5. The channel contains absorbent cotton 6 (non-woven fabric or fiber cotton, etc.) and an isolation net 7 (with crisscrossing mesh holes for connecting the upper and lower spaces) located between the absorbent cotton 6 and the enclosed space. The isolation net 7 allows water vapor to pass through so that it can be absorbed by the absorbent cotton 6, and also prevents food from entering the absorbent cotton 6. Furthermore, it also includes an isolation plate 8 covering the channel. The isolation plate 8 is screwed to the lid and is located on the side of the absorbent cotton 6 away from the isolation net 7. The isolation plate 8 and the absorbent cotton 6 are spaced apart. The isolation plate 8, the absorbent cotton 6 and the inner wall of the channel form a storage space. This storage space can be used to place seasoning packets, chopsticks, etc. The isolation plate 8 is equipped with a handle.

[0019] Example 2

[0020] If the device is used to place cold dishes, fruits, etc., the bottom of the inner box 1 can be set to have a drain mesh hole that communicates with the outer box 2. The juice can flow into the gap between the outer box 2 and the inner box 1 through the drain mesh hole, so as to avoid the food from being soaked in the juice and affecting the taste and quality, and also reduce the risk of bacterial growth due to water accumulation.

[0021] The method of using this device is as follows:

[0022] Example 1: When used to hold hot food, hot food is placed in the inner box 1. A water bag or heating bag for heat dissipation can be placed between the inner box 1 and the outer box 2. The inner box 1 and the outer box 2 are screwed to the lid. The outer box 2 serves as heat insulation and heating. The absorbent cotton 6 absorbs the water vapor emitted by the hot food and reduces the humidity inside the inner box 1.

[0023] Example 2: The fruit is placed in the inner box 1. The drainage mesh at the bottom can drain excess water into the gap between the outer box 2 and the inner box 1, preventing the fruit from soaking in the juice and becoming soft and tasteless. The absorbent cotton 6 can absorb the released moisture and prolong the freshness of the fruit.

[0024] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
