750 ml Stainless Steel Thermos with Engraving

This 750 ml thermos is designed for hot or cold drinks taken to work, kept in a car, or carried outdoors. Both the outer body and inner flask are made of stainless steel, while the double-wall construction slows heat transfer between the contents and the surroundings. The stated retention time for heat and cold is up to 12 hours. Decorative engraving adds character to the silver-coloured surface without changing the thermos’s practical travel format.

Construction details that matter

The model has a tall upright body without a handle. Its overall dimensions are 83 × 83 × 280 mm, and the thermos weighs 410 g. These measurements make it possible to check the fit of a backpack side pocket, vehicle bottle holder, or travel-bag compartment before use. The mouth is 45 mm wide, providing practical access for pouring tea, coffee, or water and for rinsing the inner flask.

• 750 ml capacity. It provides a personal drink supply for a longer drive, work shift, walk, fishing trip, or picnic.
• Steel inner flask. Stainless steel is used for the drink container as well as the exterior section of the body.
• Double-wall structure. The two-wall design reduces heat transfer and helps retain the drink’s starting temperature for longer.
• Cup-style outer lid. The outer cap can be used for drinking, removing the need to carry a separate mug for a roadside or outdoor break.
• Valve closure. A valve section closes the mouth, while the threaded connection secures the lid to the thermos body.
• Storage sleeve included. The sleeve is intended for carrying and storing the thermos; this item also comes with a cardboard box.

Filling, carrying, and routine care

The thermos is suitable for tea, coffee, water, and other non-carbonated drinks. Carbonated liquids are not recommended because pressure building inside the closed vessel may affect the valve and lid. Before carrying the filled thermos, close the valve completely, screw the lid on without cross-threading, and make sure the sealing components sit evenly. Avoid filling the flask to the rim, as some space is needed for the closure to seat normally.

After use, rinse the interior with warm water and a mild detergent. Clean the lid, valve, and seal separately because drink residue can collect around these parts. Abrasive powders and harsh cleaning compounds are unsuitable for the steel surfaces. Leave the thermos open until every part has dried completely. This model is not intended for a dishwasher or microwave oven.

When checking whether this version suits your equipment, consider its 750 ml capacity, 280 mm height, 83 mm base width, and handle-free shape. It is a practical choice when a narrow travel thermos with a steel flask, its own drinking cup, and engraved decoration is preferred.
