Thermal mug LAMART LT4045 400 ml stainless steel vacuum insulated travel cup, Ø 6.4 cm

LAMART LT4045 is a 400 ml stainless steel thermal mug engineered for travel and everyday use. The vacuum-insulated double-wall construction and stainless steel inner liner reduce heat transfer to maintain beverage temperature for extended periods. The compact form with a 6.4 cm diameter and a nearly unbreakable build provides reliable portability for commuting, trips, or office use. The lid features a push-button opening mechanism with an integrated safety lock to prevent accidental spills.

Advantages

The vacuum insulation ensures slower heat loss for hot drinks and reduced warming for cold drinks while the stainless steel interior resists stains and odors. The push-button lid offers one-handed operation and the safety lock prevents unintentional opening during movement. Its compact diameter fits many cup holders and the 400 ml capacity balances between a generous serving and easy handling. Durable materials and a sealed lid minimize leakage and contribute to long-term use.

Suitable for

• Hot beverages such as coffee or tea for commuting and office use
• Cold drinks during travel, outdoor activities, or workouts
• Use in cars where a compact diameter fits most cup holders
• Everyday carry when a spill-resistant container is needed

How to use

To open the mug, release the safety lock and press the push-button to operate the lid with one hand. Pour the desired beverage into the mug without exceeding the 400 ml capacity. Close the lid until it clicks and engage the safety lock before placing the mug in a bag or vehicle to reduce the risk of accidental opening. For hot liquids, allow a short cooling period after pouring if necessary and hold the insulated body rather than the lid to avoid heat transfer.

Recommendations

Hand wash the lid and perform periodic cleaning of the stainless steel interior with warm soapy water; the outer body can be wiped with a damp cloth. Avoid placing the lid or the entire mug in a dishwasher unless manufacturer guidance confirms dishwasher safety. Do not use with carbonated beverages or dry-ice chilled contents. Inspect seals and locking mechanisms regularly and replace if damaged to maintain leak resistance.
