A 3-Litre Unbreakable Stainless Steel Vacuum Flask is a large-capacity thermal container designed for keeping beverages hot or cold for extended periods.1

This size and description often refer to a large Thermos-style Jug or an Airpot dispenser, which is ideal for catering, offices, large family gatherings, or outdoor events.2

• Capacity: 3 Litres (or 3.0 L)3

• Material:Stainless Steel (both the inner and outer body).4 The stainless steel construction is what makes it unbreakable compared to traditional glass-lined flasks.5

• Insulation:Double-Walled Vacuum Insulation.6 The vacuum space between the two steel walls is key to providing excellent temperature retention, keeping the contents hot or cold for up to 12-24 hours, depending on the specific model and external temperature.7

• Color: Silver (the natural finish of the stainless steel).8

• Temperature Retention (Typical):

  • Keeps hot: Often holds temperatures above 60°C (140°F) for 10-12 hours.9

  • Keeps cold: Can keep beverages cold (below 10°C/50°F) for 24 hours or more.10

• Common Design/Dispensing:

  • Thermos Jug Style: May have a screw-on stopper and an integrated cup/lid.11

  • Airpot Style: Frequently features a pump-action push button on the top for easy, one-handed dispensing without lifting the flask.12 This style often has a safety lock, a rotating base, and a carry handle.

• Durability: Highly durable, rust-resistant, and designed to withstand knocks and heavy use.13
