1.0L vacuum flask

Product Detailed Description

One fill carries a whole shift, a day on the trail or a table of tea drinkers. The one liter vacuum flask sits at the generous end of the range, built for commuters, outdoor groups, site crews and families who pour for several people at once.

Double walled stainless steel construction with an evacuated space between the walls slows heat transfer, so hot drinks stay hot and cold drinks stay cold over hours of use. The body is steel with a screw or stopper closure and a mouth wide enough to fill and clean without fuss. Larger bodies add heft, so check wall thickness and base stability when sampling.

Buyers often pair the flask with a printed thermos flask sleeve or a color vacuum flask finish to match a campaign palette. A carry handle or protective sleeve helps once the flask is full and heavy.

Sizes across the range:

• 350ml
• 500ml
• 750ml
• 1000ml

Practical sourcing checks start with capacity and the fill line, then lid thread quality, seam finish and how the outer surface holds up to handling. Compare carton counts and mixed-color packing, and confirm how the flask behaves when tipped before committing to a volume across the size band.
