Description

Technical Field

[0001] This utility model relates to the field of tea oil storage technology, and in particular to a UV-resistant, light-proof tea oil storage container. Background Technology

[0002] Camellia oil is a high-quality vegetable oil rich in unsaturated fatty acids, vitamin E, and natural antioxidants, widely used in the edible, cosmetic, and pharmaceutical fields. However, the active ingredients in camellia oil are extremely sensitive to light, heat, and oxygen. In particular, under ultraviolet radiation, it is prone to photo-oxidation, leading to rancidity, darkening of color, loss of nutrients, and even the production of harmful substances, seriously affecting its quality and shelf life.

[0003] Currently, most tea oil packaging on the market uses transparent or light-colored glass bottles, plastic buckets, or ordinary metal cans. Although they have basic sealing functions, they lack effective light protection, especially in blocking strong ultraviolet rays. Long-term storage in a light environment can easily cause quality deterioration.

[0004] Therefore, it is necessary to design a UV-resistant, light-proof storage container for tea oil. Utility Model Content

[0005] In order to overcome the shortcomings of existing tea oil storage containers that lack light-proof and ultraviolet-blocking functions, the purpose of this utility model is to provide a light-proof tea oil storage container that is UV-resistant.

[0006] The technical solution is as follows: A UV-resistant tea oil storage tank includes a tank body, a lid, support feet, an oil filling valve, an oil dispensing valve, a light-shielding layer, an inner liner, a scale window, and a protective cover. The lid is fixedly installed on the upper end of the tank body by bolts. A certain number of support feet are fixedly connected to the bottom of the tank body. An oil filling valve is fixedly installed on the upper right side of the lid. A light-shielding layer is fixedly installed on the inner periphery of the tank body. An inner liner is fixedly installed inside the light-shielding layer. An oil dispensing valve is fixedly installed on the lower right side of the tank body. The oil dispensing valve passes through the tank body and the light-shielding layer and communicates with the inside of the inner liner. The oil filling valve communicates with the inside of the inner liner. A scale window is fixedly installed on the front side of the tank body. The scale window passes through the tank body, the light-shielding layer, and the inner liner. A protective cover is slidably installed on the scale window located on the outside of the tank body. The protective cover is made of a retractable material and is only slid open when checking the tea oil storage level, and remains light-shielding at other times.

[0007] As a further preferred option, the light-shielding layer is made of aluminum foil or black polyethylene material, and the outer wall is coated with a UV-resistant coating.

[0008] As a further preferred option, the oil valve is a rotary or push-button check valve.

[0009] As a further preferred option, the scale window is made of frosted transparent material.

[0010] As a further preferred option, a color-changing label is also included, which is fixedly installed below the scale window in the inner liner area. The color-changing label contains ultraviolet-sensitive material.

[0011] As a further preferred option, it also includes an air inlet valve and a sealing ring. An air inlet valve is fixedly installed on the upper left side of the can lid. The air inlet valve is connected to the inside of the inner liner and is used to inject food-grade nitrogen. A sealing ring is fixedly installed on the lower side of the can lid. When the can lid covers the can body and the inner liner, the sealing ring seals the gaps in the upper part of the light-blocking layer.

[0012] The beneficial effects are as follows: 1. This utility model achieves the effect of effectively blocking external light, especially ultraviolet light, by setting a light-blocking layer made of aluminum foil or black polyethylene material and spraying an anti-ultraviolet coating on the inner periphery of the can, thus preventing the tea oil from undergoing photo-oxidation reaction and maintaining its nutritional components and quality.

[0013] 2. This utility model achieves the effect of minimizing the impact of light on tea oil by setting a sliding protective cover to cover the outside of the scale window, so that it is only briefly exposed when checking the storage quantity, and kept completely away from light at other times.

[0019] Example: A UV-resistant, light-proof storage container for tea oil, such as... Figures 1-4As shown, the tank includes a tank body 1, a tank cover 2, support legs 3, an oil injection valve 4, an oil extraction valve 5, a light-shielding layer 6, an inner liner 7, a scale window 8, and a protective cover 9. The tank cover 2 is bolted to the upper end of the tank body 1. A certain number of support legs 3 are fixed to the bottom of the tank body 1. The oil injection valve 4 is fixedly installed on the upper right side of the tank cover 2. The light-shielding layer 6 is fixedly installed on the inner periphery of the tank body 1. The inner liner 7 is fixedly installed inside the light-shielding layer 6. The oil extraction valve 5 is fixedly installed on the lower right side of the tank body 1. The oil extraction valve 5 passes through the tank body 1 and the light-shielding layer 6 and connects to the inner liner 7. The tank body 1 is connected to the inner liner 7. The oil filling valve 4 is connected to the inner liner 7. A scale window 8 is fixedly provided on the front side of the tank body 1. The scale window 8 passes through the tank body 1, the light-shielding layer 6 and the inner liner 7. A protective cover 9 is slidably provided on the scale window 8 located on the outside of the tank body 1. The protective cover 9 is made of retractable material. The protective cover 9 is only slid open when checking the tea oil storage. At other times, it is kept in the light-shielding position. The light-shielding layer 6 is made of aluminum foil or black polyethylene material, and the outer wall is sprayed with an anti-ultraviolet coating. The oil dispensing valve 5 is a rotary control type or a press-type one-way valve. The scale window 8 is made of frosted transparent material.

[0020] like Figure 2 and Figure 3 As shown, it also includes a color-changing label 10, which is fixedly installed at the lower part of the scale window 8 located in the inner liner 7. The color-changing label 10 contains ultraviolet-sensitive material.

[0021] like Figure 1 and Figure 3 As shown, it also includes an air inlet valve 11 and a sealing ring 12. An air inlet valve 11 is fixedly installed on the upper left side of the can lid 2. The air inlet valve 11 is connected to the inside of the inner liner 7 and is used to inject food-grade nitrogen. A sealing ring 12 is fixedly installed on the lower side of the can lid 2. When the can lid 2 covers the can body 1 and the inner liner 7, the sealing ring 12 seals the gap in the upper part of the light-shielding layer 6.

[0022] This device is used when tea oil needs to be stored. First, the tea oil is injected into the inner liner 7 through the oil injection valve 4 at the top of the can lid 2. The inner liner 7 is located inside the can body 1, and a light-shielding layer 6 is fixed around its perimeter. The light-shielding layer 6 is made of aluminum foil or black polyethylene material, and its outer wall is sprayed with an anti-ultraviolet coating, which can effectively block external light, especially the penetration of ultraviolet rays. After the tea oil is injected, food-grade nitrogen can be injected into the inner liner 7 through the air inlet valve 11 to expel the air in the can and reduce the risk of oxidation. During this process, the sealing ring 12 on the periphery of the lower end face of the can lid 2 is always tightly fitted with the can body 1 and the inner liner 7 to achieve a good seal. The support feet 3 keep the can body 1 at a certain distance from the placement surface to prevent the bottom from getting damp. When it is necessary to check the tea oil storage level, the protective cover 9 located on the front side of the can body 1 is manually slid open. The protective cover 9 is a removable... The retractable material opens only when viewing and remains closed at other times to maintain a light-proof environment for the scale window 8. Through the scale window 8, made of frosted transparent material, the liquid level of tea oil in the inner liner 7 can be clearly seen. The scale window 8 runs through the tank body 1, the light-proof layer 6, and the inner liner 7 to ensure accurate readings. A color-changing label 10 is fixedly installed at the lower part of the scale window 8 inside the inner liner 7. This label contains ultraviolet-sensitive material. If the light-proof layer 6 or the protective cover 9 is damaged, causing the tea oil inside to be exposed to ultraviolet light, the color-changing label 10 will change color, indicating to the user that the tea oil may have been affected by light. When tea oil needs to be taken out, the oil dispensing valve 5 is opened. The oil dispensing valve 5 is a rotary or push-button one-way valve that runs through the tank body 1 and the light-proof layer 6 and communicates with the inside of the inner liner 7 to control the flow of tea oil. After use, the oil dispensing valve 5 is closed.
