AI Technical Summary

Technical Problem

Traditional food boxes are prone to leaking when high-temperature water vapor condenses, and auxiliary boxes are prone to sliding and overturning, making them inconvenient to use.

Method used

A concave placement groove and a leak-proof groove are set in the box cover. The leak-proof groove is provided with air holes and reflux holes. The leak-proof cover and the reflux holes are aligned. The condensed water vapor flows back into the leak-proof groove, and the air holes discharge the remaining water vapor to prevent water leakage. At the same time, the placement groove design stabilizes the auxiliary box.

Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and in particular to a breathable and leak-proof food box (food box) for placing food ingredients, such as lunch boxes, hot pot boxes, etc. Background Art

[0002] Food boxes are widely used, such as lunch boxes and hot pot boxes. These boxes typically hold heated ingredients, such as soup, and require ventilation holes to allow the food to breathe and maintain internal and external pressure balance. Traditional food boxes typically only have ventilation holes on the lid. Some also have a sealing cover near the holes, which is kept closed when the box is not in use to prevent dust from entering. The sealing cover is opened to facilitate ventilation when the box is in use. A disadvantage of this structure is that when the hot water vapor inside is discharged through the ventilation holes, it condenses onto the cooler surface of the lid. Once the water droplets accumulate to a certain level, they can flow out, soaking the food bag or other items, causing inconvenience. While some boxes are designed with anti-flow structures, these significantly increase the box's complexity. Furthermore, traditional food boxes typically have flat lids. When used with auxiliary boxes, such as smaller boxes specifically for rice, the auxiliary box can easily slip and tip over when placed on the lid of the main box. Utility Model Content

[0003] The utility model aims to solve the defects of the prior art and provide a breathable and leak-proof food box which has a simple structure, a more reasonable design, can prevent water leakage, and is more stable and convenient for stacking auxiliary boxes.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a breathable and leak-proof catering food box, comprising a box body and a box lid, characterized in that: a concave placement groove is provided in the box lid, the bottom of the placement groove is a flat surface, and a concave leak-proof groove is provided in the placement groove; a first air hole is provided on the leak-proof groove, and the first air hole is connected to the interior of the box body; a plurality of reflux holes are provided along the edge of the leak-proof groove, and the reflux holes connect the leak-proof groove and the placement groove; it also includes a leak-proof cover with a shape and size matching the leak-proof groove, and a plurality of upwardly concave second air holes are provided along the bottom edge of the leak-proof cover, and after the leak-proof cover covers the leak-proof groove, its second air holes are opposite to the reflux holes.

[0005] Furthermore, a handle is provided on the edge of the leak-proof cover, and the handle is opposite to one of the reflux holes. After the leak-proof cover covers the leak-proof groove, the handle is embedded in the reflux hole opposite to it.

[0006] Furthermore, a protrusion is provided at the center of the leakage-proof groove, and the first air vent is provided on the protrusion to prevent condensed water from flowing back into the box body.

[0007] Furthermore, the placement groove is arranged in the central area of ​​the surface of the box cover, and the leakage-proof groove is arranged in the central area of ​​the placement groove.

[0008] Furthermore, a plurality of auxiliary support bars are provided in the leak-proof groove, and each auxiliary support bar props up the leak-proof cover to prevent the leak-proof cover from being deformed by pressure.

[0009] Furthermore, a cover edge extending outward is provided on the edge of the leak-proof cover. When the leak-proof cover covers the leak-proof groove, the cover edge covers the outer edge of the leak-proof groove.

[0010] Preferably, 3-8 reflux holes are provided, which are evenly spaced from each other, and each reflux hole is a slot-shaped arc hole; the number of the second air holes is one less than the number of the reflux holes.

[0011] The utility model provides a leak-proof groove in the box lid, and a first air vent in the leak-proof groove; a leak-proof cover is provided for the leak-proof groove, a second air vent is provided along the edge of the leak-proof cover, and a reflux hole is provided along the edge of the leak-proof groove; after the leak-proof cover is placed on the leak-proof groove, the second air vent is aligned with the reflux hole. When water vapor is discharged from the first air vent, a portion of it hits the leak-proof cover and condenses into water, which then falls back into the leak-proof groove. The remaining water vapor is discharged through the second air vent, and most of it hits the surface of the box lid and condenses into water droplets, which flow back into the leak-proof groove through the reflux hole, thereby preventing water from leaking out. In addition, by providing a concave placement groove in the box lid, the auxiliary box is not likely to slide out and overturn when placed on it, which facilitates use.
