Insulated & Reusable Water Bottles

For best results, please ensure that the starting temperature of your contents is as warm as possible, filled to maximum capacity and the lid is sealed properly.

We also recommend that the flask is pre-warmed before the contents are added. Simply fill the flask with boiling water, seal with the lid and leave for 5-10 minutes. Please do not fill the flask higher than the inner line marking inside the flask.

Carefully tip out the boiling water, fill with your hot food and seal the lid.

To check if your insulated bottle or flask is working properly, simply fill with boiling water and the outer surface should remain cool to touch.  If the bottle/flask is hot to touch on the outer wall, the insulation may have become compromised – please contact our customer service team by clicking here.

Whilst some Smash products are considered top rack dishwasher safe, this is highly dependent on the material the product is made from.

For product specific information, please refer to the product packaging or the markings on the base of the product to determine if it is top rack dishwasher safe or handwash only. You can find additional information under the Care and Use section of the FAQ’s.

If your product features a printed design, we often recommend hand washing to extend the life of your product. This includes when the product is marked as top rack dishwasher safe.

All products in the Smash range are BPA free!

BPA (Bisphenol A) is a chemical used to make a wide variety of products such as plastic bottles, containers and food lining. Recently, concerns have been raised about the safety of BPA. Smasia Enterprises ensure that all products are BPA Free and are safe to use.

The food contact surfaces such as the inside lining of our lunch bags and coolers are phthalate free* and have been tested and confirmed by leading international testing bodies.

*Phthalate free means that the products are tested against the leading international standards and confirmed to be free from (7P) phthalates.

To avoid mould, please ensure your product is left to thoroughly air dry before reassembling or storing.   We recommend storing drink bottles with the lid removed or flip top left open, to allow air flow and to prevent a moist environment.

If mould is detected on silicone parts, then we recommend the following:

1. Apply white vinegar to the mould area and leave to sit for half an hour or even overnight if it is a dense area.
2. Use a soft cloth to work the vinegar covered mould in a circular motion until it starts to loosen and then wipe clean.
3. If the mould is very stubborn, try a mixture of vinegar and bicarbonate soda to create a paste which can be applied to the mould affected area and left on overnight.   Then use a soft cloth to remove the paste and rinse.
