Description

Technical Field

[0001] The utility model relates to the technical field of daily utensils, in particular to a food supplement jar. Background Art

[0002] A food supplement jar is a container used to hold milk powder or supplementary food at home or when going out. Due to the need to carry it out, it generally has good sealing properties.

[0003] For example, the technical solution disclosed in Chinese patent CN218967727U is: a multifunctional thermal insulation supplementary food can, comprising: an upper cover, a can body is installed below the upper cover, a cavity is arranged inside the can body, and the cavity is communicated with the upper port of the can body, an annular groove is formed between the lower end of the cavity and the can body, an annular insulation body is arranged inside the annular groove, a center hole is formed at the axial position of the insulation body, and the cavity is inserted inside the center hole, the lower port of the insulation body is sealed with a sealing cover, and the lower port of the can body is installed with a lower cover.

[0004] The above-mentioned supplementary food cans in the prior art have sealing and heat preservation functions, but they do not have the function of automatic pressure relief. When the supplementary food can is filled with high-temperature food, a high pressure greater than one atmosphere is easily formed in the supplementary food can due to the high temperature inside the can. When in use, for example, when opening the can, it is easy to cause the risk of scalding due to the sudden splashing of food or soup. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a food supplement jar with good sealing performance, which can automatically deflate when the air pressure inside the jar is too high and has a simple structure. In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A food supplement can comprises an outer cover which covers each other, and a can body with an opening at the top, a sealing cover also covers the outer cover and the can body, a sealing ring is provided at the lower part of the sealing cover, the sealing ring is placed at the opening of the can body, and at least one protrusion is provided on the outer side wall of the sealing ring, when the air pressure in the can body is not greater than one atmosphere, the sealing ring and the can body form a sealed state, when the air pressure in the can body is greater than one atmosphere, the sealing ring is lifted and the can body is released from the seal to form a pressure relief state.

[0007] On the basis of adopting the above technical solution, the utility model can also adopt the following further technical solution:

[0008] A handle is provided on the sealing ring.

[0009] The center of the upper surface of the sealing cover is concave downwards and the lower surface of the sealing cover is convex downwards to form a first arc-shaped cover body.

[0010] The center of the upper surface of the outer cover is concave downwards and the lower surface of the outer cover is convex downwards to form a second arc-shaped cover body.

[0011] The concave curvature of the first arc-shaped cover body is the same as the convex curvature of the second arc-shaped cover body.

[0012] The inner side wall of the outer cover is provided with a clamping groove, and the outer peripheral edge of the sealing cover is provided with a clamping ring. When the outer cover, the sealing cover and the can body are covered with each other, the clamping ring and the clamping groove abut against each other to seal.

[0013] The sealing ring is in the form of an inclined ring body which is wider at the top and narrower at the bottom.

[0014] The center of the bottom of the tank body bulges upward to form a first flow-guiding arc surface.

[0015] The tank body is in a shape with a gradually increasing diameter from the tank mouth to the tank bottom, and the tank bottom is an arc-shaped corner forming a second flow-guiding arc surface.

[0016] The outer cover is connected to the tank body via threads.

[0017] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0018] The utility model can realize that when the air pressure in the tank increases, the sealing cover is automatically lifted upward to release air through the design of the protrusion on the sealing cover, and the structural design of the outer cover and the sealing cover with the middle lower and the two ends higher can not only make the outer cover press the sealing cover downward to make it difficult for the sealing cover to fall off, but also form an airflow guiding arc surface that spreads to both sides on the bottom surface of the sealing cover, making it easier to exhaust air when the air pressure in the tank is too high. At the same time, combined with the protrusion and arc corner design at the bottom of the tank body, it is more conducive to airflow guidance and exhaust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In conjunction with the accompanying drawings, a supplementary food jar provided by the utility model is further described.

[0028] Embodiment 1, as Figure 1-7 As shown, a food supplement can comprises an outer cover 1 which covers each other, and a can body 2 with an upper opening, and a sealing cover 3 is also covered between the outer cover 1 and the can body 2.

[0029] The center of the upper surface of the outer cover 1 is concave downwards and the lower surface of the outer cover 1 is convex downwards to form a second arc-shaped cover body 11 .

[0030] Furthermore, the center of the upper surface of the sealing cover 3 is concave downwards and the lower surface of the sealing cover 3 is convex downwards to form a first arc-shaped cover body 31 .

[0031] Furthermore, the concave curvature of the first arc-shaped cover body 31 is the same as the convex curvature of the second arc-shaped cover body 11 .

[0032] Furthermore, a clamping groove 12 is provided on the inner wall of the outer cover 1, and a clamping ring 32 is provided on the outer periphery of the sealing cover 3. When the outer cover 1, the sealing cover 3 and the can body 2 are covered with each other, the clamping ring 32 and the clamping groove 12 abut against each other to seal.

[0033] Furthermore, the center of the bottom of the tank body 2 bulges upward to form a first flow-guiding arc surface 21 .

[0034] Furthermore, the tank body 2 is shaped such that the diameter gradually increases from the tank mouth to the tank bottom, and the tank bottom is an arc-shaped corner forming a second guide arc surface 22 .

[0035] Furthermore, the outer cover 1 and the tank body 2 are connected via threads.

[0036] Among them, a sealing ring 33 is provided at the lower part of the sealing cover 3, and the sealing ring 33 is placed at the opening of the tank body 2. The outer wall of the sealing ring 33 is provided with at least one protrusion, which is a convex point 34 in this embodiment, and can also be other forms of protrusions, such as ribs, vertical bars, irregular protrusions, etc., as long as they have a convex shape.

[0037] When the air pressure in the tank body 2 is not greater than one atmosphere, the sealing ring 33 and the tank body 2 form a sealed state. When the air pressure in the tank body 2 is greater than one atmosphere, the sealing ring 33 is lifted and released from the tank body 2 to form a pressure relief state.

[0038] Furthermore, a handle 35 is provided on the sealing ring 33 to facilitate the loading and unloading of the sealing cover 3 .

[0039] Furthermore, the sealing ring 33 is an inclined ring body that is wider at the top and narrower at the bottom, which makes it easier to install the sealing cover 3 at the opening of the tank body 2.

[0040] The present invention has been illustrated and described with reference to the preferred embodiments. However, it will be understood by those skilled in the art that various changes in form and details may be made within the scope of the claims.
