Description

Technical Field

[0001] This utility model relates to the field of food storage technology, and in particular to a food preservation and sealing container. Background Technology

[0002] Food preservation airtight containers are essential tools specifically designed to maintain the freshness and quality of food. These containers are typically made of durable and safe materials and come in various shapes, such as round, square, and rectangular, to meet different usage needs and space arrangements. The design of these containers emphasizes airtightness, featuring a tightly fitting lid that ensures a good airtight seal when closed, effectively preventing the entry of air, moisture, and odors, and preventing food from being contaminated and oxidized. Traditional food preservation airtight containers cannot expel air from inside the container when sealing food, resulting in low preservation efficiency. Furthermore, the good seal makes the lid difficult to open when removing food, making them inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to provide a food preservation and sealing container to solve the technical problems existing in the prior art.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A food preservation and sealing container includes: a sealing container body, which is open on one side, hollow inside, and has a predetermined accommodating space; an internal thread is formed on the top of the inner wall of the sealing container body to allow gas to escape from inside the sealing container body; an exhaust cover is provided inside the sealing container body and close to its inner wall, the exhaust cover is provided with an external thread on its outer side, the exhaust cover can be raised and lowered on the inner wall of the sealing container body, a plurality of exhaust holes are formed on the working surface of the exhaust cover, and a handle is provided at the middle position of the top of the exhaust cover for easy control of raising and lowering.

[0006] Furthermore, the top of the exhaust cover is provided with a sealing soft cover, which has a predetermined toughness and an internal through hole in the middle position, the through hole being inserted into the handle.

[0007] Furthermore, the working dimensions of the sealing soft cover are larger than those of the exhaust cover.

[0008] Furthermore, the working dimensions of the sealing soft cap and the vent cap are smaller than the working dimensions of the sealing container body; the working dimensions of the internal thread and the external thread are adapted to each other.

[0009] Furthermore, the height of the sealed container body is 10cm and its diameter is 8cm; the length of the internal thread 2 is 3cm.

[0010] Furthermore, the wall height of the exhaust cover is 0.5 cm.

[0011] Furthermore, the outer side of the sealed container body is coated.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, through the design of internal and external threads and an exhaust cap, allows for the release of gas from the sealed container body by twisting the handle during food storage, improving preservation efficiency and simplifying the process. The soft sealing cap isolates the interior of the sealed container body from the outside air, achieving optimal preservation. Attached Figure Description

[0018] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figure 1-3As shown, this embodiment provides a food preservation and sealing container, including: a sealing container body 1, which is made of food-grade plastic material. The sealing container body 1 has an opening on one side and is hollow inside, having a predetermined accommodating space. The outer side of the sealing container body 1 is coated with a coating 9, which is made of polytetrafluoroethylene and has non-stick, high and low temperature resistance, and corrosion resistance properties. The sealing container body 1 has a height of 10cm and a diameter of 8cm. An internal thread 2 is formed on the top of the inner wall of the sealing container body 1, and the length of the internal thread 2 is 3cm. An exhaust cover 3 is provided inside the sealing container body 1, which is close to its inner wall. The exhaust cover 3 has a wall height of 0.5cm and an external thread 6 on its outer side. The working dimensions of the internal thread 2 and the external thread 6 are adapted to each other. The exhaust cover 3 can be raised and lowered inside the sealing container body 1. Several exhaust holes 4 are formed on the working surface of the exhaust cover 3, and a handle 5 is provided at the top center. When sealing and preserving food, the handle 5 drives the vent cap 3 to rotate inside the sealed container body 1. At this time, the internal thread 2 and the external thread 6 interlock, and the air inside the sealed container body 1 is squeezed out through the vent hole 4, thereby reducing the probability of microorganisms in the air coming into contact with the food and improving the preservation effect. The vent cap 3 has a sealing soft cap 7 on top. The sealing soft cap 7 has a predetermined toughness and a through hole 8 in the middle of its interior. The sealing soft cap 7 is made of soft latex, and the through hole 8 is inserted into the handle 5. The working size of the sealing soft cap 7 is larger than that of the vent cap 3. When in use, the sealing soft cap 7 is placed on the upper surface of the vent cap 3 to isolate the inside of the sealed container body 1 from the outside air and lock in the freshness of the food. The working size of the sealing soft cap 7 and the vent cap 3 is smaller than that of the sealed container body 1. When in use, the vent cap 3 and the sealing soft cap 7 are embedded inside the sealed container body 1.

[0020] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
