Features of Lug Caps
A Lug Cap is a metal cap designed for glass bottles and jars. It occupies an important position in the packaging industry with its unique design and excellent performance. The main features of Lug Cap include the following:
Material and Construction: Lug Cap is usually made of high-quality metal, such as tinplate or aluminum alloy, to ensure its robustness and durability. The cap is fitted with a plastic sol gasket, which provides an excellent seal and prevents leakage or external contamination of the contents of the bottle.
Unique lug design: The Lug Cap has a series of lugs protruding inwards at equal distances from the cap surface. These lugs engage with the intermittent external threads of the bottle top, creating a unique opening and closing mechanism. This design not only simplifies handling but also allows the cap to open and close more smoothly.
Quick Unscrew and Close: The best feature of the Lug Cap is its quick unscrew and close feature. The cap can be easily unscrewed or re-closed by rotating it less than one turn. This convenient operation greatly improves work efficiency and reduces operation difficulty.
Good sealing: The sealing performance of the Lug Cap is greatly enhanced by the combination of a metal cap and a plastic sol gasket. This seal not only prevents leakage of the contents of the bottle but also prevents outside air and impurities from entering the bottle, thus ensuring the quality and safety of the contents.
Wide range of applications: Lug Cap is suitable for a variety of glass bottle packaging that requires a good seal and easy opening. For example, Lug Cap is widely used in the packaging of various bottled products in the beverage, condiment, and sauce industries. Its convenient opening and closing method and good sealing performance have won the favor of consumers.

Deep twist off lug caps size: 38#, 43#, 48#, 53#, 58#, 63#, 66#, 70#, 77#, 82#, 90#
How does Lug Cap work?
The working principle of the Lug Cap is mainly based on its unique lug design and the external threaded structure of the bottle mouth.
Unscrewing Process: When it is time to open the Lug Cap, simply gently rotate the cap with your finger. Due to the design of the lugs engaging with the outer threads, the cap will easily unscrew in less than one turn. This design makes the opening process more convenient and saves time and effort.
CLOSING PROCESS: When closing the Lug Cap, again simply rotate the cap gently with your finger. The cap will slide smoothly down the outer threads during rotation and eventually close tightly against the mouth of the bottle. At this point, the plastic sol-gel gasket will fit snugly into the mouth of the bottle, creating a good seal.
Sealing Principle: The sealing performance of Lug Cap is mainly due to the design of the plastic sol-gasket. This gasket will fit snugly into the mouth of the bottle when the cap is closed, forming a reliable barrier. At the same time, the tight contact between the metal cap and the mouth of the bottle further enhances the sealing effect and ensures the safety and quality of the substance inside the bottle.
Applications of Lug Caps
Lug Cap has a wide range of application scenarios in the packaging industry, especially in glass bottles that need to be well sealed and easy to open. Below are some of the main application scenarios for Lug Cap:
Beverage industry: In the beverage industry, Lug Cap is widely used in the packaging of various bottled beverages, such as carbonated beverages, fruit juices, milk, and so on. Its convenient opening and closing method and good sealing performance make it more convenient for consumers to drink, and at the same time ensure the quality and safety of beverages.
Condiment industry: Lug Cap is also widely used in the packaging of various bottled condiments, such as soy sauce, vinegar, and sauce. Its sealing performance can effectively prevent condiments from leaking or being contaminated from outside, ensuring the quality and taste of the products.
Food industry: In addition to the beverage and condiments industry, Lug Cap is also widely used in food packaging, such as honey, jams, pickles, etc.
