Put the construction beside the product name
“Thermos flask” and “insulated bottle” can be used for different shapes and constructions in enquiries. Confirm the actual model, capacity, lid and whether it is vacuum insulated.
Use the same construction and model reference in the quote, sample, packing and listing. That gives everyone a clear description even when the product names overlap.
Single vs Double Wall Construction
Single-wall: one layer without an insulation gap. Compare its permitted filling temperature, capacity and carrying style with the intended use.
Double-wall describes two layers. A non-vacuum body has an air gap; a vacuum body has air drawn out between the walls. Discuss any retention information for the selected model rather than applying one hour figure to each construction.
Vacuum Insulation Explained
Vacuum manufacturing forms and seals an insulated cavity between the walls. We can explain the relevant production steps for your chosen model and show the body-check stage before finishing.
Vacuum bodies are checked before assembly and finishing. This keeps the check early in production, while anything needing attention can be addressed.
What This Means for Your Sourcing Decision
Start with what the drinkware will be used for, then compare the available constructions. We can put the selected build and care information in the quote and product brief.
If your programme requests a particular test or retention figure, send the model, conditions and scope while the order is being quoted. We can discuss the available data and any new test arrangement.
Browse our vacuum flask range for available models; how long coffee stays hot discusses the model and conditions behind retention information.
Frequently asked questions
Confirm the construction in the selected model’s product details. If heat retention is part of your brief, we can discuss available model data and its test conditions; the sample gives you a reference for the body, lid and handling.
Flask retention depends on the model, capacity, fill level, starting temperature and lid use. We can discuss the data available for your selected model and its test conditions.
Double-wall describes the body’s two layers; it does not by itself confirm vacuum construction. We state the construction for the selected model and can help compare options for your intended use.
Tell us the drink, serving conditions and carrying style you have in mind. We can compare single-wall, double-wall non-vacuum and vacuum models and confirm the chosen construction, quantity and production schedule in the quote.
