Description

Technical Field

[0001] The utility model relates to a lunch box, in particular to a takeout lunch box with a heat insulation structure at the mouth edge. Background Art

[0002] With the development of the takeout industry, takeout lunch boxes have become the carriers for merchants to hold food and are widely used in daily life. However, existing takeout lunch boxes are often made of plastic materials. Once high-temperature food is placed in them, the temperature is easily conducted to the lunch box. Especially when users pick up and open the lid, the hot steam leaking from the gap can easily make users feel burned, or even get burned.

[0003] To solve this problem, lunch box manufacturers on the market have launched various products. For example, a heat-insulated fast food box provided by the prior art CN209547277U uses ear plates and a bottom plate to insulate the lunch box, thereby preventing the lunch box from scalding users. However, it still has great drawbacks: ① The production cost is high. Adding complex structures inside often increases its production cost and difficulty. As lunch boxes are consumables in large quantities and are used quickly, these structures will cause the cost to rise significantly. ② It mainly solves the problem of preventing scalding when users hold the lunch box, but does not solve the problem of high temperature at the joint between the box body and the lid, especially when taking the lunch box out of the microwave oven. This means that when users open or hold the lunch box, they will still be affected by the high-temperature steam, causing discomfort to users.

[0004] To solve the above problems, this solution designs a takeout lunch box with a heat insulation structure at the mouth edge. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a takeout lunch box with a heat insulation structure at the mouth edge, including: a box body and a lid.

[0006] A buckling platform is provided at the mouth edge of the box body. The outside of the buckling platform bulges upward to form a sealing rib. A vertical first sealing section is provided between the sealing rib and the buckling platform. The top of the sealing rib is a first heat insulation section and is connected to a heat insulation groove through a buckling section and an inclined section;

[0007] A buckling rib that can cooperate with the buckling platform is provided at the lower part of the lid. The buckling rib extends outward to form a sealing groove. The sealing groove includes: a second sealing section, a heat insulation section, a sealing section, and a pressing section;

[0008] When the box cover is buckled on the box body, the buckling rib is clamped on the buckling platform, the sealing rib and the sealing groove cooperate with each other to seal the box body, the second sealing section abuts against the first sealing section, the sealing section and the buckling section cooperate to seal the box body, and at the same time, a heat insulation gap is formed between the second heat insulation section and the first heat insulation section.

[0009] Wherein, an easy-opening section is provided on the heat insulation groove, and the easy-opening section is connected to the box body through a plurality of tearable connection points.

[0010] Wherein, the buckling section is provided with a first rib.

[0011] Wherein, the sealing section is provided with a second rib, and the second rib cooperates with the first rib for clamping.

[0012] Wherein, the sealing groove is fastened to the first rib through the first rib and the second rib, and the pressing section is elastically pressed on the inclined section.

[0013] Wherein, the length of the second sealing section is less than the length of the first sealing section, and when the box cover and the box body are buckled with each other, an elastic gap is formed between the buckling rib and the buckling platform.

[0014] Wherein, the top of the box cover has a shed top protruding upward, and the bottom of the box body has a reinforcing part protruding upward.

[0015] Implementing the embodiments of the present invention has the following beneficial effects: ① The box body and the box cover are sealed by the sealing rib, the buckling platform, the buckling protrusion and the two-section structure of the sealing groove, which increases the sealing performance, and at the same time enables heat to pass through the two-section structure before being conducted to the joint of the box body and the box cover. ② On the premise of ensuring the sealing performance, a heat insulation gap is formed between the first heat insulation section and the heat insulation section, reducing the heat at the upper and lower positions of the edge of the lunch box, so that the influence of high temperature can be minimized when holding it. ③ The production cost is low, and the heat insulation and anti-scalding functions at the mouth edge are realized through a simple structure. Such simple and practical structural improvements are more suitable for products such as lunch boxes that are consumed in large quantities. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 5 It is a partially enlarged sectional view showing the box body and the box cover of the present utility model when they are buckled. Specific embodiments

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As Figure 1 shown, a takeout food container with a heat-insulating structure at the rim includes: a box body 1 and a box cover 2.

[0023] As Figures 2 to 4 shown, a buckling platform 11 is provided at the rim of the box body 1. The outside of the buckling platform 11 bulges upward to form a sealing rib 12. A vertical first sealing section 121 is provided between the sealing rib and the buckling platform. The top of the sealing rib 12 is a first heat-insulating section 122, and is connected with a heat-insulating groove 13 through a buckling section 123 and an inclined section 124.

[0024] A buckling rib 21 that can cooperate with the buckling platform 11 is provided at the lower part of the box cover 2. The buckling rib 21 extends outward to form a sealing groove 22. The sealing groove 22 includes: a second sealing section 221, a heat-insulating section 222, a sealing section 223 and a pressing section 224.

[0025] When the box cover 2 is buckled on the box body 1, the buckling rib 21 is clamped on the buckling platform 11. The sealing rib 12 and the sealing groove 22 cooperate with each other to seal the box body. The second sealing section 221 abuts against the first sealing section 121. The sealing section 223 and the buckling section 123 cooperate to seal the box body 1. At the same time, a heat-insulating gap is formed between the second heat-insulating section 222 and the first heat-insulating section 122.

[0026] It should be particularly noted that in this embodiment, a heat-insulating gap is formed by the radian of the end face of the first heat-insulating section 122 and the second heat-insulating section 222. Here, it is necessary to combine the actual life. When holding the food container, the index finger of a person generally supports the lower part of the edge of the box body, and at the same time, the thumb abuts against the upper part of the edge of the box cover from bottom to top.

[0027] This solution uses two structures, the buckling rib 21 and the sealing rib 12, to make it more difficult for the heat inside the lunch box to transfer to the edge of the lunch box, that is, the position of the heat insulation groove 13. Above, through the heat insulation gap between the second heat insulation section 222 and the first heat insulation section 122, the heat transferred to the upper part of the edge of the lid 2 is reduced, so that this lunch box is less likely to be affected by temperature when picked up.

[0028] An easy-opening section 131 is provided on the heat insulation groove 13. The easy-opening section 131 is connected to the box body 1 through a number of tearable connection points. Then, the user can break the easy-opening section 131 to separate the box body 1 and the lid 2, and thus it is easier to open the lid 2.

[0029] As Figure 4 shown, the buckling section 123 is provided with a first rib 1231, the sealing section 223 is provided with a second rib 2231, the second rib 2231 is engaged and connected with the first rib 1231, and the sealing groove 22 is fastened to the first rib 1231 through the first rib 1231 and the second rib 2231, so that the box body 1 and the lid 2 are connected more tightly.

[0030] Please combine Figure 4 、 Figure 5 , the inclination angle of the pressing section 224 is greater than the slope of the inclined section 124. Then, the pressing section 224 can utilize the elasticity of the plastic material of the lunch box and elastically press on the inclined section 124, so that the lid 2 exerts an inward squeezing force on the box body 1, and thus the lid 2 can be more tightly closed on the box body 1.

[0031] Please combine Figure 5 , the length of the second sealing section 221 is less than the length of the first sealing section 121. When the lid 1 and the box body 2 are buckled with each other, there is an elastic gap between the buckling rib 21 and the buckling platform 11. The beneficial effect here is that it can prevent the upper lunch box from flattening the lower lunch box when multiple lunch boxes are stacked. Specifically, when a lunch box presses on the lid 2 of another lunch box, the lid 2 is stressed. At this time, due to the elastic gap between the buckling rib 21 and the buckling platform 11, the pressure is absorbed by the elastic gap and the elastic gap is reduced during the process, and it is less likely to crush the lunch box.

[0032] More preferably, the top of the lid 2 has a shed top 23 protruding upward, and the bottom of the box body 1 has a reinforcing part 14 protruding upward. The shed top 23 and the reinforcing part 14 are used to strengthen the structural strength of the lid and the box body.

[0033] Certainly, the above embodiments are only used to illustrate the technical concept and features of the present utility model. The purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model. All modifications made according to the spirit and essence of the main technical solution of the present utility model should be covered within the protection scope of the present utility model.
