Description

Technical Field

[0001] This utility model relates to the technical field of pre-made food containers, and in particular to a breathable pre-made food container. Background Technology

[0002] Pre-cooked meals are basically pre-made dishes that can be transformed into different forms and characteristics of delicious food by using different methods and undergoing a final cooking process. With the fast pace of life, pre-cooked meals are becoming increasingly popular. Instant hot food refers to food that only needs to be heated before consumption, which can be summarized as "heat-and-eat" food. Typical examples are fast food meal kits that have been very active in the market in the past two years, such as braised pork with preserved mustard greens, spicy diced chicken, etc. These pre-cooked meals are packaged in lunch boxes, and then sealed to the box with a lid film before being sold.

[0003] When existing pre-cooked food containers are used and microwaved, the food inside generates steam as it heats up. The hot air inside expands until the container randomly breaks open. Once the container reaches its expansion limit, it is prone to bursting. At the same time as the explosion, the food or soup may spray out. Such containers are not very safe. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a breathable pre-cooked food container that can effectively prevent the food container from bursting and avoid the pre-cooked food inside from splashing out due to an explosion, thereby improving the safety of the food container.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a breathable pre-prepared food container, comprising a container body and a safety breathable component disposed on the side of the container body. A sealing platform is integrally fixed on the top of the container body, and a heat-sealed cover film is installed on the sealing platform. The safety breathable component includes a pressure relief pipe and a T-shaped silicone plug. A pressure relief hole is provided on the side of the container body communicating with the interior. The pressure relief pipe is fixedly installed on the pressure relief hole communicating with the interior of the container body. The T-shaped silicone plug is sealed at the output end of the pressure relief pipe. A connecting rod is fixedly connected to the right end of the T-shaped silicone plug. A movable plate is fixedly connected to the right end of the connecting rod. Two sets of limiting grooves are symmetrically provided on the inner wall of the pressure relief pipe to cooperate with the movable plate. The movable plate is movably installed inside the pressure relief pipe by cooperating with the two sets of limiting grooves.

[0007] Preferably, a handheld piece is fixedly connected to one side of the outer wall of the sealing platform.

[0008] Preferably, the edge of the cover film is integrally fixed with a tear strip.

[0009] Preferably, the outer wall of the lunchbox is fixed with multiple sets of reinforcing ribs arranged in a ring array.

[0010] Preferably, two sets of silicone sealing rings are fixedly connected to the outer wall of the T-shaped silicone plug.

[0011] Preferably, the handheld piece has multiple anti-slip grooves at both the top and bottom ends.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the food container contains pre-cooked food. The lid is fixedly adhered to the top of the sealing platform using heat-sealing technology. The T-shaped silicone plug is installed on the pressure relief pipe, providing a seal and preventing external dust and impurities from entering. When microwaving the pre-cooked food, the food container containing the pre-cooked food is placed in the microwave oven. As the pre-cooked food heats, the internal pressure of the food container gradually increases under the action of steam. When the internal steam pressure of the food container exceeds the frictional force between the T-shaped silicone plug and the inner wall of the pressure relief pipe, the steam pressure begins to push the T-shaped silicone plug... The T-shaped silicone stopper slides outward, causing the movable plate to slide outward along the limiting groove via the connecting rod. This detaches the T-shaped silicone stopper from the pressure relief pipe, allowing it to be pushed open by steam pressure. The limiting action of the movable plate and the limiting groove prevents the T-shaped silicone stopper from flying off. After the T-shaped silicone stopper is pushed open, steam escapes from the inside of the food container through the pressure relief pipe, maintaining the pressure balance inside the food container. After heating, the lid can be torn off for consumption. This effectively prevents the food container from bursting and splashing out the pre-cooked food due to an explosion, thus improving the safety of using the food container.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] Example

[0022] Please see Figures 1-6 This utility model discloses a breathable pre-prepared food container, comprising a container body 1 and a safety ventilated component disposed on the side of the container body 1. A sealing platform 2 is integrally fixed to the top of the container body 1, and a heat-sealed cover 3 is fitted onto the sealing platform 2. The safety ventilated component includes a pressure relief pipe 5 and a T-shaped silicone plug 6. A pressure relief hole 4 is provided on the side of the container body 1, communicating with the interior. The pressure relief pipe 5 is fixedly installed on the pressure relief hole 4, communicating with the interior of the container body 1. The T-shaped silicone plug 6 is fitted as a sealing cap at the output end of the pressure relief pipe 5. A connecting rod 7 is fixedly connected to the right end of the T-shaped silicone plug 6, and a movable plate 8 is fixedly connected to the right end of the connecting rod 7. Two sets of limiting grooves 9 are symmetrically provided on the inner wall of the pressure relief pipe 5 to cooperate with the movable plate 8. The movable plate 8 is movably installed inside the pressure relief pipe 5 by cooperating with the two sets of limiting grooves 9. In use, the food container 1 contains pre-cooked food, and the lid film 3 is fixedly pasted to the top of the sealing platform 2 by heat sealing technology. The T-shaped silicone plug 6 is installed on the pressure relief pipe 5 to seal it and prevent external dust and impurities from entering. When microwave-heating pre-cooked food, the container 1 containing the pre-cooked food is placed in the microwave oven for heating. As the pre-cooked food heats up, the internal pressure of the container 1 gradually increases under the action of steam. When the internal steam pressure of the container 1 exceeds the sealing friction between the T-shaped silicone plug 6 and the inner wall of the pressure relief pipe 5, the steam pressure begins to push the T-shaped silicone plug 6 outward, causing the T-shaped silicone plug 6 to slide outward along the limiting groove 9 via the connecting rod 7, thereby causing the T-shaped silicone plug 6 to slide outward from the limiting groove 9. The pressure relief pipe 5 is detached, allowing the T-shaped silicone plug 6 to be pushed open under steam pressure. The T-shaped silicone plug 6 is prevented from being blown away by the limiting cooperation of the movable plate 8 and the limiting groove 9. After the T-shaped silicone plug 6 is pushed open, steam is discharged from the inside of the lunch box 1 through the pressure relief pipe 5, maintaining the pressure balance inside the lunch box 1. After heating, the lid film 3 can be torn off and the food can be eaten. This effectively prevents the lunch box from bursting and avoids the pre-cooked food inside from splashing out due to an explosion, thus improving the safety of using the lunch box.

[0023] A handheld piece 11 is fixedly connected to one side of the outer wall of the sealing platform 2; by setting the handheld piece 11, the lunch box can be more convenient to take out.

[0024] The cover film 3 is integrally provided with a tear strip 10 along its edge; by providing the tear strip 10, the cover film 3 can be torn open more easily and conveniently.

[0025] Multiple sets of reinforcing ribs 12 are fixedly arranged in a ring array on the outer wall of the lunch box body 1. By setting the reinforcing ribs 12, the structural strength of the lunch box body 1 can be effectively improved, the pressure bearing capacity of the lunch box body 1 can be improved, and the lunch box body 1 is not easy to deform during transportation.

[0026] Two sets of silicone sealing rings 13 are fixedly connected to the outer wall of the T-shaped silicone plug 6. By setting the silicone sealing rings 13, when the T-shaped silicone plug 6 is installed on the pressure relief pipe 5, the T-shaped silicone plug 6 and the pressure relief pipe 5 can fit more tightly, thus improving the sealing performance.

[0027] The handheld piece 11 has multiple anti-slip grooves 14 at both the top and bottom ends. By setting the anti-slip grooves 14, the friction between the top and bottom surfaces of the handheld piece 11 can be improved, and the hand is less likely to slip when holding the handheld piece 11 to carry the lunch box 1.

[0028] This utility model discloses a breathable pre-cooked food container. Its working principle is as follows: During use, the container body 1 contains pre-cooked food. The cover film 3 is fixedly adhered to the top of the sealing platform 2 using heat-sealing technology. A T-shaped silicone plug 6 is installed on the pressure relief pipe 5 to provide a seal, preventing external dust and impurities from entering. When the pre-cooked food is microwaved, the container body 1 containing the pre-cooked food is placed in the microwave oven. As the pre-cooked food heats, the internal pressure of the container body 1 gradually increases under the action of steam. When the internal steam pressure of the container body 1 exceeds the sealing pressure between the T-shaped silicone plug 6 and the inner wall of the pressure relief pipe 5... When the friction force is applied, the steam pressure pushes the T-shaped silicone stopper 6 outward, causing the T-shaped silicone stopper 6 to slide outward along the limiting groove 9 via the connecting rod 7, thereby causing the T-shaped silicone stopper 6 to detach from the pressure relief pipe 5. The T-shaped silicone stopper 6 is pushed open under the action of steam pressure, and the limiting cooperation between the moving plate 8 and the limiting groove 9 prevents the T-shaped silicone stopper 6 from being pushed away. After the T-shaped silicone stopper 6 is pushed open, the steam is discharged from the inside of the food container 1 through the pressure relief pipe 5, maintaining the pressure balance inside the food container 1. After heating, the lid film 3 can be torn open with the tearing piece 10 and it is ready to eat.

[0029] The present invention relates to a breathable pre-made food container, the installation method, connection method or setting method of which are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
