Description

Technical Field

[0001] The invention relates to the technical field of steaming and stewing containers, and in particular to a sealed steaming and stewing container and a cooking method thereof. Background Art

[0002] The traditional way to eat bird's nest is to soak it in water, wash it, and stew it over a slow fire, which takes a long time. At present, people live at a fast pace and cannot spend time stewing bird's nest every day, but they want to eat bird's nest every day. Although the instant bird's nest sold on the market is convenient to eat, it contains preservatives or has quality problems with raw materials, which makes it difficult for consumers to eat it with confidence. A bird's nest steaming container that can achieve simultaneous stewing in multiple containers and is easy to carry has emerged. However, the current steaming containers mostly use glass bottles. The sealed glass bottles will generate internal pressure expansion during the steaming process, which can easily cause the glass bottles to burst. Summary of the invention

[0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a sealed steaming and stewing container and a cooking method thereof.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] A sealed steaming and stewing container comprises a steaming and stewing container body provided with an opening and a bottle cap provided at the opening, wherein the bottle cap comprises a circular ring structure portion and a plane structure portion, an elastic pad is provided under the plane structure portion, the elastic pad comprises a safety valve extending into the opening, an outer ring edge formed outward is provided at the opening of the safety valve, the outer ring edge is arranged between the plane structure portion and the opening, an elastic safety button is provided in the middle of the plane structure portion, and a hollow cavity is formed between the safety button and the safety valve.

[0006] The sealed steaming and stewing container of the present invention is provided with an elastic pad, and a safety button is provided in the middle of the planar structure part, and a hollow cavity is formed between the safety button and the safety valve on the elastic pad. During the steaming and stewing process, the safety valve is deformed and bulged upward under the action of pressure, and the air in the hollow cavity is squeezed to push the safety button of the bottle cap to bulge upward, which has the effect of reducing the pressure in the container. The present invention is suitable for steaming and stewing bird's nests, can realize simultaneous stewing in multiple containers, stew once and eat multiple times, and is easy to carry.

[0007] In addition, when the food in the container deteriorates, gas will be generated in the container. The gas expansion will bulge the safety valve of the elastic pad. The air in the hollow cavity will be squeezed to push the safety button of the bottle cap upward, which also serves to remind the user to determine whether the food in the bottle is deteriorated.

[0008] Preferably, the safety valve of the elastic pad is a concave structure with a thin middle and thick edges, which is beneficial for the middle part of the safety valve to deform and bulge upward under the action of pressure during the steaming process, thereby reducing the pressure in the container.

[0009] Preferably, an exhaust gap is provided between the safety valve and the inner wall of the opening.

[0010] More preferably, the exhaust gap between the safety valve and the inner wall of the opening is ≥0.1 mm.

[0011] An exhaust gap is provided between the safety valve and the inner wall of the opening, which is conducive to exhausting the air in the container when assembling the elastic pad and preventing the air in the bottle from squeezing the safety valve of the elastic pad during assembly, thereby affecting the use effect.

[0012] Preferably, an exhaust groove A is provided on the lower surface of the outer ring edge, and the exhaust groove A is communicated with the exhaust gap.

[0013] More preferably, the depth of the exhaust groove A is >0.05 mm.

[0015] An exhaust channel is formed between the exhaust groove A and the matching gap. When the pressure in the container increases, the pressure in the container is released from the exhaust gap through the exhaust groove A to prevent the container from bursting during the steaming process.

[0016] Preferably, the upper surface of the outer ring edge is provided with an exhaust groove B, the exhaust groove B is connected to the hollow cavity, the safety valve is provided with an exhaust groove C, and the interior of the steaming and stewing container body is connected to the hollow cavity through the exhaust groove C.

[0017] More preferably, the depth of the exhaust groove B is >0.05 mm.

[0018] An exhaust groove B is provided on the upper surface of the outer ring edge, and an exhaust groove C is provided on the safety valve. An exhaust channel is formed between the exhaust groove C, the hollow cavity, the exhaust groove B, and the matching gap. During the stewing process, when the pressure in the container increases, the pressure in the container is released from the exhaust groove B through the exhaust groove C, which plays a role in protecting the container.

[0019] Preferably, the bottle cap is sealed and connected to the steaming and stewing container body by means of threads or buckles; the elastic pad is a silicone pad; and the material of the steaming and stewing container body is glass.

[0020] The present invention also provides a cooking method using the sealed steaming and stewing container, comprising the following steps: putting the bird's nest after being soaked and cleaned into the sealed steaming and stewing container, sealing the sealed steaming and stewing container, placing the sealed steaming and stewing container in a stewing device, and stewing the bird's nest through a three-stage heating and sterilization process:
