Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a dustproof packaging box. Background Art

[0002] Plastic food packaging is a plastic container commonly used for food packaging. It is usually made of food-grade plastic materials, with the characteristics of transparency, impact resistance, high temperature resistance, moisture resistance, and oxidation resistance, which can effectively protect the freshness and quality of food. Plastic food packaging has various shapes and sizes, such as square, round, rectangular, etc., to accommodate different types and sizes of food. They usually have a sealable lid or a snap-on structure to ensure that the food will not spill or be contaminated by impurities such as dust during the packaging process.

[0003] However, at present, there are still some shortcomings in the use of plastic packaging boxes with dust-proof function used in the take-out industry: some packaging boxes with an overall round shape are usually used to pack pasta and other foods with soup. At present, for the packaging of pasta and other foods with soup, the soup is usually placed in the packaging box, and then the staple food such as noodles is placed in a transparent plastic bag for separate packaging. Although this can solve the problem of pasta becoming lumpy to a certain extent, since the soup usually has a high temperature, after the soup is poured into the packaging box, the lid is closed during the delivery process. The hot water vapor will liquefy and form water droplets attached to the inner wall of the lid when it encounters the cold inner wall of the lid. Since the buckle connection between the lid and the packaging box is usually relatively tight, when the user opens the lid, the water droplets attached to the inner wall of the lid are easily splashed when the user opens the lid forcefully, causing pollution to the user's clothes and the environment, affecting the user's eating experience. Therefore, a dust-proof packaging box is proposed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when a user opens the lid, water droplets attached to the inner wall of the lid are easily splashed due to force to open the lid, causing pollution to the user's clothes and the environment, and proposes a dust-proof packaging box.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A dustproof packaging box comprises a first box body and a cover body, a first cavity is opened on the top of the first box body, a limiting ring is fixedly installed on the inner wall of the first cavity, a second box body is placed inside the first cavity, the bottom of the second box body touches the top surface of the limiting ring, and the outer wall of the second box body fits the inner wall of the first cavity, a second cavity is opened on the top of the second box body, and four convex edges are evenly fixedly installed on the top surface of the inner wall of the second cavity.

[0007] Preferably, a flange is fixedly mounted on the top surface of the first box body.

[0008] Preferably, the top surface of the first box body is clamped with a cover body, and the bottom surface of the cover body is provided with a groove.

[0009] Preferably, the radius of the top surface of the limiting ring is the same as the radius of the bottom surface of the second box body.

[0010] Preferably, the top projections of the first box body and the cover body are both circular, and the bottom surface of the first box body is provided with anti-slip grooves.

[0011] Preferably, the top projection of the limiting ring is in the shape of a circular ring.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting a limiting ring, the second box body and the convex edge for use together, when using the device to hold pasta food, the noodle soup can be placed inside the first cavity, and then the pasta staple food is placed inside the second cavity, and the second box body is placed inside the first cavity and supported by the limiting ring. At the same time, the outer wall of the second box body fits the inner wall of the first cavity, which can greatly reduce the contact of hot water vapor with the inner wall of the cover body during the distribution process. Therefore, when the user opens the cover body, the splashing of the inner wall of the cover body due to the attached water droplets can be greatly reduced, which can improve the user's eating experience.

[0014] 2. By providing a second box body, a second cavity and a convex edge for holding staple foods of noodles, the existing method of holding the staple foods in plastic bags can be replaced, which makes it more convenient and quick to take out the staple foods of noodles. In addition, compared with plastic bags, the second box body has a stronger ability to resist rupture, which can greatly reduce the occurrence of spillage of staple foods of noodles caused by accidental rupture of plastic bags during delivery.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A dustproof packaging box includes a first box body 1 and a cover body 8. A flange 3 is fixedly installed on the top surface of the first box body 1. Further, the flange 3 is integrally formed with the first box body 1. The first box body 1 is made of the same material as the common transparent plastic packaging boxes on the market. No further details are given here. The top surface of the first box body 1 is clamped with the cover body 8. The bottom surface of the cover body 8 is provided with a groove 9. The top projections of the first box body 1 and the cover body 8 are both circular, and the bottom surface of the first box body 1 is provided with anti-slip grooves. The top of the first box body 1 is provided with a first cavity 2, and the inner wall of the first cavity 2 is fixed. A limiting ring 4 is installed, and the top projection of the limiting ring 4 is a circular ring. The second box body 5 is placed inside the first cavity 2. The radius of the top surface of the limiting ring 4 is equal to the radius of the bottom surface of the second box body 5. The bottom of the second box body 5 touches the top surface of the limiting ring 4, and the outer wall of the second box body 5 fits with the inner wall of the first cavity 2. A second cavity 6 is opened on the top of the second box body 5, and four convex edges 7 are evenly and fixedly installed on the top surface of the inner wall of the second cavity 6. Furthermore, the convex edges 7 are integrally formed with the second box body 5, and the material of the second box body 5 is the same as that of the first box body 1.
