DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0027] In the description of the present application, it should be understood that the terms "opening", "upper", "middle", "length", "inner" and the like indicate the orientation or positional relationship, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the referred components or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0028] In order to keep the following description of the embodiments of the present application clear and concise, the present application omits the detailed description of known functions and known components.

[0029] Embodiment 1: Refer to Figures 1-6 A steaming bag, comprising:

[0030] A bag body 1, the bag body 1 comprises an inner layer 2 and an outer layer 3, and is used to form the bag body 1, the outer layer 3 is fixedly connected to the outer wall of the inner layer 2, and is used to protect the inner layer 2 from damage from the outside, a reversible temperature measuring label 13 is fixedly connected to the middle part of the outer wall of the front end of the bag body 1, and is used to display the temperature of the bag body 1 in the form of observing color change;

[0031] A reinforcing assembly, the reinforcing assembly comprises a first air bag 7 fixedly installed at the connecting part of one side of the outer wall of the bag body 1, and a second air bag 8 fixedly connected at the connecting part of the other side of the outer wall of the bag body 1, and is used to seal and reinforce the connecting part of the bag body 1.

[0032] In the above technical solution, the reversible temperature measuring label 13 fixedly connected to the middle part of the outer wall of the front end of the bag body 1 can change color with the change of the temperature in the bag, thereby directly displaying the temperature of the bag body. This design enables the user to accurately grasp the temperature change during the steaming process, and ensures that the food reaches the desired degree of ripening. The core of the reversible temperature measuring label 13 is a temperature-sensitive dye, which can react to temperature changes and change color;

[0033] The reversible temperature measuring label 13 is a product in the prior art. The principle of the reversible temperature measuring label 13 is that the reversible temperature measuring label 13 usually uses a reversible temperature sensitive dye called invisible ink. The invisible ink is colorless or light-colored at low temperature and cannot be observed by the naked eye. When the temperature rises, the invisible ink changes color and becomes visible. In order to better apply the reversible temperature measuring label, the invisible ink is usually coated on thermal paper. The thermal paper is a special paper containing temperature sensitive microgel. When it is stimulated by external heat source, it will present a corresponding color through a thermal color development reaction. When the temperature returns to its original state, the color will also return to the initial state. This is due to the characteristics of the temperature sensitive dye. When the temperature rises, the dye molecules or polymers rearrange, thereby changing the light absorption performance. However, when the temperature decreases, they can return to the initial state, and the color also returns.

[0034] Meanwhile, the first air bag 7 and the second air bag 8 arranged at the connection of the bag body 1 play a sealing and reinforcing role in the cooking process, which can effectively prevent the phenomenon of sealing failure and air leakage caused by long-time cooking or external pressure, thereby ensuring the hygiene and safety of food.

[0035] In one aspect of the embodiment, as shown in Figure 1 the upper end of the bag body 1 is fixedly connected with a connecting belt 4, and the upper end of the connecting belt 4 is fixedly connected with a reinforcing belt 5 for sealing the bag body 1.

[0036] In the above technical solution, the reinforcing belt 5 is arranged to seal the bag body 1.

[0037] In one aspect of the embodiment, as shown in Figure 1 the outer walls on both sides of the connecting belt 4 are provided with triangular openings 6, the outer walls at the front end and the rear end of the reinforcing belt 5 are provided with anti-slip patterns 12, and the two sides of the reinforcing belt 5 are fixedly connected with plastic blocks 11 for tearing the connecting belt 4.

[0038] In the above technical solution, the triangular openings 6 on the connecting belt 4, the anti-slip patterns 12 on the reinforcing belt 5 and the plastic blocks 11 together constitute a convenient opening mode. The user only needs to easily tear the connecting belt 4, and then the cooking bag can be quickly opened to enjoy the food.

[0039] The present application can be used in the field of cooking bags, and can also be used in other fields applicable to the present application.

[0040] Embodiment 2: improvement based on embodiment 1: a controllable temperature vacuum cooking bag applied in the field of cooking bags,

[0041] In one aspect of the embodiment, as shown in Figure 6 the material of the inner layer 2 is a CPP film, and the material of the outer layer 3 is a BOPET film.

[0042] In the technical scheme, the inner layer 2 adopts CPP film, and the outer layer 3 adopts BOPET film, so that the two materials have good high-temperature resistance and can effectively isolate external pollution and maintain the original flavor and nutritional value of food.

[0043] In one aspect of the embodiment, as shown in Figure 5 The lower end of the annular air bag 9 is fixedly connected with a base 10.

[0044] In the technical scheme, the annular air bag 9 is arranged to further seal the connection of the lower end of the bag body 1, and the lower end of the annular air bag 9 is further fixedly connected with the base 10, so that the stability of the bag body is increased.

[0045] In another aspect of the embodiment, as shown in Figure 3 and Figure 4 The rear end of the upper inner wall of the bag body 1 is fixedly connected with a strip-shaped clamping block 14, and the front end of the upper inner wall of the bag body 1 is fixedly connected with a strip-shaped clamping groove 15, the strip-shaped clamping block 14 is clamped and matched with the strip-shaped clamping groove 15, and the bag body 1 is sealed.

[0046] In the technical scheme, the strip-shaped clamping block 14 is clamped and matched with the strip-shaped clamping groove 15, so that when the food in the bag cannot be finished, the bag can be sealed, and the practicability of the steaming bag is improved.
