China Leakproof Insulated Coffee Mug Manufacturer, Supplier, Factory
Jianyang manufactures Leakproof Insulated Coffee Mug products for daily coffee, tea, and beverage use. The mug combines a stainless steel body, double-wall vacuum insulation, and a sealed lid structure to reduce leakage during carrying. With a 500ml capacity, welded handle, and cup-holder-compatible design, it is suitable for offices, commuting, driving, travel, and outdoor activities. Jianyang provides OEM and ODM production for customized drinkware orders.
Product Overview
The Leakproof Insulated Coffee Mug is designed for users who need to carry beverages between different locations without relying on an open cup. Its sealed lid helps contain the beverage when properly closed, while the double-wall vacuum structure reduces heat transfer between the drink and the surrounding environment.
The mug is made from 18/8 stainless steel and has a 16.9 oz (500ml) capacity. A 360-degree welded handle provides a stable grip, while the soft-touch base helps keep the mug steady when placed on a desk, table, or other flat surface.
Leakproof Construction
Sealed Twist Lid
The lid uses a twist structure that secures it to the mug body. When fully closed, the sealing components help reduce the risk of liquid escaping during normal carrying and transportation.
Adjustable Drinking Opening
The drinking opening allows users to control beverage flow while drinking. Closing the opening after use provides an additional barrier against accidental spills.
Sealing Components
The sealing parts are integrated with the lid to create a closed drinking system. Keeping the sealing components clean and correctly installed is important for maintaining the intended leak-resistant performance.
Vacuum Insulation Performance
The Leakproof Insulated Coffee Mug uses a double-wall vacuum structure to slow heat transfer between the inner wall and the external environment. This design helps hot coffee, tea, and other warm beverages retain heat for longer, while cold drinks can remain cool for an extended period.
The vacuum structure also separates the beverage from the exterior surface, making the mug more comfortable to hold when it contains a hot or cold drink. Actual temperature retention depends on the starting beverage temperature, ambient conditions, filling level, and frequency of opening.

Design Details
360° Welded Handle
The welded handle connects securely with the mug body and provides a practical grip for carrying and drinking. Its shape also leaves sufficient space for hand placement without interfering with the lid.
Soft-Touch Base
The bottom of the mug uses a soft-touch base to increase contact stability on common indoor surfaces. It also helps reduce direct contact between the stainless steel body and the tabletop.
Magnetic Slide Rail
The lid incorporates a double magnetic slide rail that helps keep the drinking opening in its intended position during use. The sliding mechanism can be opened when drinking and closed when the mug is being carried.
Detachable Lid Components
Selected lid components can be removed for cleaning. This allows users to access areas around the drinking opening and sealing parts where beverage residue may accumulate.
Beverages and Usage Scenarios
Coffee and Tea
The 500ml capacity provides space for daily coffee, tea, and other warm beverages. The vacuum structure helps slow temperature loss during working hours or travel.
Cold Beverages
The same insulated construction can be used for cold water, iced beverages, and other chilled drinks when temperature retention is required.
Office Use
The mug can be placed on desks and work surfaces while its sealed lid allows users to close the drinking opening between uses. The handle provides an additional grip when moving the mug around the workplace.
Driving and Commuting
The body is designed to fit most standard vehicle cup holders. The sealed lid helps reduce spills when the mug is properly closed during transportation.
Travel and Outdoor Activities
The stainless steel construction and portable design make the Leakproof Insulated Coffee Mug suitable for road trips, camping, walking, and other outdoor activities requiring a reusable beverage container.
Cleaning and Daily Care
The mug should be cleaned after regular use with a soft sponge and mild detergent. Abrasive brushes and rough cleaning tools should be avoided to reduce the risk of scratching the surface.
Remove the detachable lid components when necessary and clean the drinking opening and sealing areas separately. After washing, allow the mug and lid components to dry completely before reassembly and storage.
