Pilfer-Proof Screw Cover Engine Oil Cap

1. Safety and environmental protection

Material Safety: Most products utilize food-grade, non-toxic, harmless, and odorless materials such as polyethylene (PE) and polypropylene (PP). These materials are food safety certified and suitable for direct contact with food, medicine, and other hygienic products.

Environmentally Friendly: Some products are made from recyclable materials, and energy consumption and waste emissions are strictly controlled during the production process, in line with green production principles. These products can be recycled and reused after use, reducing resource waste.

2. Excellent sealing performance

Leak-proof structure: The inner wall of the top is equipped with an annular leak-proof ring and a sealin ring, or the lidis designed with encrypted reinforcement ribs, which can fit tightly to the barrel mouth, effectively prevent liquid leakage and gas exchange, and prevent the contents (such as cooking oil and chemical reagents) from getting damp, oxidized and deteriorating, thereby greatly extending the shelf life.

Air pressure balance design: Some barrel lids are equipped with air valves, which can balance the air pressure inside and outside the barrel while ensuring sealing, preventing the barrel from deforming or becoming difficult to open due to pressure difference. It is especially suitable for storing volatile liquids such as solvents and paints.

3. Strong durability

Chemical corrosion resistance: It can withstand long-term contact with acids, alkalis, salts and other chemicals, and is not easy to age or break. It is an ideal choice for storing hazardous reagents in the chemical industry.

Temperature and shock resistance: It can adapt to a wide temperature range (such as -40℃ to 80℃), does not crack or deform at high temperatures, and does not crack at low temperatures; it also has excellent impact resistance and is not easily damaged after multiple drops and impact tests, and can effectively protect the contents during transportation.

4. Easy to use and efficient

Easy to open: The screw-on cap can be opened by twisting, without tools; the tear-off and pull-ring types can be opened with a gentle pull, and even people with less strength (such as women) can operate it easily.

Reusability: Press-type and hinged barrel covers can be sealed multiple times to meet the needs of repeated use (such as kitchen oil barrels and chemical sampling barrels), improving practicality.

Additional thoughtful design features: a handle for easy transport; the transparent version allows direct viewing of the oil/material level in the barrel; the oil nozzle cap precisely controls the liquid outflow rate to avoid waste and spillage (such as lubricating oil and detergent barrel caps).

5. Anti-theft and anti-tampering

Through the design of disposable tear strips and anti-theft rings, obvious traces will be left when opening the barrel (such as the tear strip breaking and the anti-theft ring remaining at the barrel mouth), which can be used to intuitively determine whether the container has been opened, effectively ensuring the safety of the contents in food, medicine, chemical and other fields.
