Description

Technical Field

[0001] This utility model relates to the field of food container technology, specifically to a disposable fast food container with reliable fastening. Background Technology

[0002] A fast food box is a box used to hold food, also known as a lunchbox or meal box. It is usually made of plastic, stainless steel or aluminum and is widely used in the catering industry. Disposable fast food boxes are used extensively in restaurants. They are usually made of heat-resistant plastic. Food is placed in the fast food box and the matching lid is quickly closed to pack the food. It has a certain effect of preventing leakage and keeping the food warm. Production is very simple, the packaging cost is low and the packaging operation is very convenient.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain defects: After the top lid of the existing disposable fast food box is fastened, the lid and the box body are initially connected, so that they will not easily separate during the transportation of food. However, if the rider encounters a large shaking during the transportation process, and the food loaded in the box is a large block with a large weight, the top lid of the box can easily be impacted by the shaking block of food, causing its edge to detach from the box body. This can easily lead to the leakage of food or liquid inside the box, and the fastening is not reliable enough. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a disposable fast food box that is highly impact-resistant, does not easily detach, and has a reliable fastening mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a disposable fastening box with reliable fastening, comprising a box body and a top cover detachably disposed on the top of the box body. The edge of the top cover is provided with a fastening part that fastens to the upper edge of the box body. Below the top cover is an impact plate that is in contact with and slidably connected to the inner wall of the box body. Between the top surface of the impact plate and the bottom surface of the top cover are a plurality of compression elastic columns made of elastic material. The top of the compression elastic column is embedded in the bottom surface of the top cover and the top of the compression elastic column is shaped like a frustum. When the food in the box body impacts the top cover, it first contacts the impact plate and the impact force is slowly absorbed by the compression elastic column. With its frustum-shaped top, the impact force is diffused and released.

[0006] A further improvement is that the fastening part is also provided with a reinforcing post that penetrates the lunchbox body.

[0007] A further improvement is that the reinforcing column includes a column body disposed on the fastening part and penetrating the box body, and a receiving groove disposed on the lower outer wall of the column body, wherein a locking block is movably engaged on the inner wall of the receiving groove.

[0008] A further improvement is that a tension block is slidably provided on the inner wall below the column, and the top surface of the tension block is connected to the locking block through a tension frame.

[0009] A further improvement is that a pull-back tab is provided between the top surface of the tension block and the inner wall below the column.

[0010] A further improvement is that the outer wall of the column is provided with several elastic hemispherical protrusions.

[0011] A further improvement is that the locking block has a fin-shaped structure.

[0012] A further improvement is that the bottom of the tension block is provided with a boss.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model can withstand the impact force generated by the food during shaking through the impact plate, and at the same time, it can absorb the impact force with the compression elastic column. The remaining part is diluted on the top cover with the frustum-shaped top, so that the unit pressure on the top cover is greatly reduced. With the reinforcement column, it can effectively prevent the top cover from detaching from the food container during shaking. The connection is firm and not easy to fall off, and it has strong resistance to impact and shaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0018] See Figure 1-2As shown, the technical solution adopted in this specific embodiment is: a disposable fastening box with reliable fastening, including a box body 1 and a top cover 2 detachably disposed on top of the box body 1. The edge of the top cover 2 is provided with a fastening part 3 that fastens to the upper edge of the box body 1. Below the top cover 2, there is an impact plate 4 that is in contact with and slidably connected to the inner wall of the box body 1. Between the top surface of the impact plate 4 and the bottom surface of the top cover 2, there are several compression elastic columns 5 made of elastic material. The top of the compression elastic column 5 is embedded in the bottom surface of the top cover 2 and the top of the compression elastic column 5 is frustoconical. When the food in the box body 1 impacts the top cover 2, it first contacts the impact plate 4 and the impact force is slowly absorbed by the compression elastic columns 5. With its frustoconical top, the impact force is further... The food is placed into the lunchbox body 1 during use, followed by the top cover 2. The top cover 2 is then connected to the lunchbox body 1 via the fastening part 3, which seals the top of the lunchbox body 1. At the same time, the impact plate 4 is pressed into the inner wall of the lunchbox body 1. When the food inside the lunchbox body 1 shakes and impacts the top cover 2, the impact plate 4 first contacts the food and then transmits the impact to the elastic compression column 5, which absorbs the impact force. A small portion of the additional impact force is distributed to the top cover 2 through the frustum-shaped structure at the top of the elastic compression column 5, which greatly reduces the unit pressure on the top cover 2 and thus greatly reduces the degree of shaking of the top cover 2. This prevents the fastening part 3 from detaching from the lunchbox body 1 and greatly enhances the connection.

[0019] The fastening part 3 is also provided with a reinforcing post 6 that penetrates the lunch box body 1. The reinforcing post 6 includes a post 61 disposed on the fastening part 3 and penetrating the lunch box body 1, and a receiving groove 65 disposed on the outer wall below the post 61. A locking block 66 is movably engaged on the inner wall of the receiving groove 65. When the fastening part 3 is fastened into the lunch box body 1, the reinforcing post 6 penetrates the lunch box body 1 at the same time. The locking block 66 is pressed into the receiving groove 65 during the process of penetrating the lunch box body 1, and extends out again by gravity when it exits the lunch box body 1. Thus, when the top cover 2 is impacted, the locking block 66 presses against the outer surface of the lunch box body 1 to prevent the top cover 2 from falling off, thereby effectively enhancing the anti-detachment effect of the top cover 2 and making the connection stronger.

[0020] A tension block 62 is also slidably provided on the inner wall below the column 61. The top surface of the tension block 62 is connected to the locking block 66 through the tension frame 64, which facilitates the quick pullback of the locking block 66 through the tension frame 64 after the tension block 62 is pulled down, thereby making it easier to disassemble the top cover 2.

[0021] A pull-back tab 63 is also provided between the top surface of the tension block 62 and the lower inner wall of the column 61, which helps the tension block 62 to recover quickly, and thus prevents the reinforcement column 6 from failing when the tension block 62 is accidentally pulled.

[0022] The outer wall of the column 61 is also provided with several elastic hemispherical protrusions. In this embodiment, four protrusions are provided, which helps to increase the friction when the column 61 penetrates the lunch box body 1, making it less likely to fall off.

[0023] The locking block 66 has a fin-shaped block structure, which helps to further enhance the locking effect by pressing the top against the surface of the lunch box body 1;

[0024] The bottom of the pull block 62 is provided with a boss, which makes it easier to pull down the pull block 62 without it slipping out of your hand.

[0025] The working principle of this utility model is as follows: When using this utility model, food is placed into the lunch box body 1, and then the top cover 2 is installed. The top cover 2 is connected to the lunch box body 1 by the fastening part 3, which seals the top of the lunch box body 1. At the same time, the impact plate 4 is pressed into the inner wall of the lunch box body 1. When the food in the lunch box body 1 shakes and impacts the top cover 2, the impact plate 4 first contacts the food and then transmits the impact of the food to the elastic compression column 5 to squeeze the elastic compression column 5 to absorb the impact force. The additional small part of the impact force is distributed to the top cover 2 through the frustum-shaped structure at the top of the elastic compression column 5, which greatly reduces the unit pressure on the top cover 2, thereby greatly reducing the degree of shaking of the top cover 2. This prevents the fastening part 3 from detaching from the lunch box body 1 and greatly enhances the connection firmness.
