Technical Field

[0001] This utility model relates to the field of paper lunch box technology, specifically an improved flip-top paper lunch box. Background Technology

[0002] With increasing environmental awareness, paper lunch boxes are becoming more and more widely used in the food delivery and fast food industries due to their advantages such as being biodegradable and environmentally friendly. Flip-top paper lunch boxes are favored by the market because of their ease of use and ability to be opened and closed quickly.

[0003] In the prior art, Chinese patent CN215125100U discloses a paper lunch box with internal partitions, including a lunch box base and a lunch box lid. The lunch box base includes a main shell, a slot, a paper soup box, a receiving slot, a paper slider, and a sliding cardboard. The lunch box lid includes a top plate, a connecting plate, and a snap plate. The main shell has a slot, and the snap plates on both sides of the lid combine to facilitate the sealing function of the lunch box body. The main shell is equipped with a paper slider and a paper soup box. When the user needs it, the soup box can be slid to divide the internal space of the lunch box. When the user does not need it, the paper soup box can be removed without occupying the internal partition space of the lunch box, making it convenient for the user.

[0004] Based on the above information, it is clear that the existing technology of the flip-top paper lunch box is only fixed to the main body of the lunch box by a snap-on plate, which has poor sealing performance. During transportation, it is easy for soup to leak and food to spill out, which will not only pollute the outer packaging and the surrounding environment, but may also affect the consumer's dining experience. Therefore, we propose an improved flip-top paper lunch box. Utility Model Content

[0005] The purpose of this utility model is to provide an improved flip-top paper lunch box to solve the problem mentioned in the background art where the flip-top of the lunch box is only fixed to the main body of the lunch box by a buckle plate, resulting in poor sealing. During transportation, soup leakage and food spillage are likely to occur, which will not only pollute the outer packaging and the surrounding environment, but may also affect the consumer's dining experience. Therefore, we propose an improved flip-top paper lunch box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved flip-top paper lunch box, comprising a lunch box body, a flip-top on the top of the lunch box body, reinforcing ribs inside the lunch box body, a first placement groove and a second placement groove on the top of the flip-top, a positioning block fixedly installed at the bottom of the lunch box body, anti-slip texture on the outer wall of the lunch box body, a sealing structure for sealing the lunch box body on the outer wall of the lunch box body, the sealing structure including a sealing block on the top of the lunch box body, an opening and closing handle fixedly installed on the side wall of the flip-top, an embedded block fixedly installed on the outer wall of the opening and closing handle, and a limiting protrusion on the outer wall of the embedded block, and a slot on the outer wall of the lunch box body.

[0007] Furthermore, the reinforcing ribs are distributed in a grid pattern inside the main body of the lunchbox, and the thickness of the reinforcing ribs is less than the thickness of the outer wall of the main body of the lunchbox.

[0008] Furthermore, the main body of the lunch box and the flip-top of the lunch box are connected by a connecting strip, and the connecting strip is made of flexible paper material for folding the flip-top of the lunch box.

[0009] Furthermore, the sealing block has a trapezoidal cross-section and its thickness is less than the thickness of the top wall of the lunch box body. The outer wall of the lunch box flap has a sealing groove that matches the sealing block, and the inner wall of the sealing groove fits into the outer wall of the sealing block.

[0010] Furthermore, the opening and closing handle is located on the outer wall of the lunch box lid away from the connecting strip, the embedded block has a rectangular cross-section, and the corners of the embedded block are beveled. The embedded block is located on the outer wall of the lunch box body close to the opening and closing handle.

[0011] Furthermore, the limiting protrusion is hemispherical in shape and is equidistantly distributed on the outer wall of the embedding block. The inner wall of the slot is in contact with both the outer wall of the limiting protrusion and the outer wall of the embedding block.

[0012] Furthermore, the anti-slip texture is symmetrically arranged on both sides of the outer wall of the lunch box body, and the anti-slip texture is designed in a wavy shape to increase the friction of the outer wall of the lunch box body.

[0013] Furthermore, the first placement slot is used to place chopsticks, the second placement slot is perpendicular to the first placement slot, and the opening depth of the second placement slot is less than that of the first placement slot. The cross-section of the second placement slot is trapezoidal, and the inner wall of the second placement slot is symmetrically provided with locking blocks for placing disposable spoons.

[0014] Furthermore, the positioning block is designed in the shape of a frustum, and the positioning blocks are evenly distributed at the bottom of the lunch box body. The top of the lunch box lid is provided with a positioning groove that matches the positioning block, and the inner wall of the positioning groove fits into the outer wall of the positioning block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This improved flip-top paper lunch box significantly enhances sealing performance through its sealing structure. The trapezoidal sealing block on the top of the lunch box body fits tightly with the sealing groove on the outer wall of the flip-top, forming a more effective sealing barrier compared to the traditional buckle fixing method. This effectively prevents soup leakage and food spillage, avoiding contamination of the outer packaging and the surrounding environment. The combination of the opening and closing handle, the embedded block, and the limiting protrusion makes opening and closing the lunch box more convenient and ensures that the lid is securely closed, greatly improving the consumer's dining experience.

[0017] 2. The internal grid-like reinforcing ribs of the lunch box effectively enhance the structural strength of the lunch box without adding too much material. While ensuring strength, it also takes into account the lightweight nature and cost control of paper lunch boxes, enabling the lunch box to withstand a certain amount of external pressure, making it less prone to deformation and damage, and extending its service life.

[0018] 3. The corrugated anti-slip texture on the outer wall of the lunch box is symmetrically arranged, which effectively increases the friction of the outer wall, making it easy for users to pick up the lunch box and preventing it from slipping. The first and second placement slots on the top of the lunch box lid are used to place chopsticks and spoons respectively. The locking block on the inner wall of the second placement slot can firmly hold the spoon, making it easy for users to store tableware, improving the convenience of use, and further optimizing the user experience.

[0019] 4. The frustum-shaped positioning block at the bottom of the lunchbox body precisely matches the positioning groove on the top of the lunchbox lid. When multiple lunchboxes are stacked, the positioning block can be tightly embedded in the positioning groove to form a stable nested structure, effectively preventing the lunchboxes from being misaligned or tipped over during stacking. Even during bumpy transportation, it can ensure that the food is not squeezed or collided, providing reliable safety for food transportation. At the same time, the neat stacking method also makes it easier for merchants to store and deliver, improving delivery efficiency. Attached Figure Description
