Vacuum Flask Water Bottle

Backed by the same production standards we deliver to global brands. Our 20,000㎡ facility runs automated CNC stretching and high vacuum inner tank lines, and every bottle moves through a 5 step quality check before shipment: raw material inspection, insulation test, leak proof verification, paint adhesion, and a final product audit. We hold BSCI, Sedex, WCA, ISO9001, ISO14001, and RCS certifications, which means safety and consistency are built into the process, not just promised.

What makes this 260ml bottle different

The extended body holds 30% more water than our 200ml version, yet the overall weight stays low enough for everyday carry. It fills the gap between mini flasks and bulky travel mugs. The extra length fits standard desk drawers, bag side pockets, and most car cup holders. For parents juggling a child and a shopping bag, the flip handle ring frees a hand. For an office worker, one fill covers a whole morning at the desk.

We upgraded the vacuum flask water bottle liner to a thicker food grade 304 stainless steel, paired with an optimized double wall vacuum. In daily use, boiling water stays warm for 6 to 9 hours. The outer wall remains cool to the touch with hot drinks and stays condensation free when filled with ice water, even in humid summer weather. The inner liner is one piece deep drawn, so there are no seams or ridges where scale could build up, and the smooth surface wipes clean easily.

A food grade silicone seal and a precisely machined screw lid keep the bottle drip free, even when shaken upside down in a bag. Every part of the lid assembly can be taken apart by hand, making it easy to scrub away residue from flower tea, goji berries, or fruit infusions.

The exterior uses an environmentally friendly matte spray paint in soft macaron colors. The finish resists scratches and fingerprints, giving it a premium look that stays fresh after months of daily handling. A reinforced PP handle ring adds carrying convenience without adding noise or loose parts.

How our customers put it to use

Office workers keep it on the desk for flower tea or warm water, reducing trips to the pantry. The slender profile slides into shallow drawers when not in use.

Parents take it for outdoor play and grocery runs. A single fill supplies half a day’s water, and the handheld design helps when you are already holding a child.

Commuters and students rely on it inside the car or library. The quiet, leak proof build means it sits safely next to a laptop or in a cup holder.

Corporate buyers order it as employee gifts, client souvenirs, or training center giveaways. The simple, universally liked shape works for men and women, across all age groups.

Practical tips from our QC team

Preheat the inner liner with hot water for about 20 seconds before pouring in boiling water. This small habit can add roughly 2 hours of heat retention.

When filling with very hot liquids, leave 1 to 2 cm of space below the rim. Hot water expands slightly, and this prevents any overflow when you close the lid.

Plain water stays fresh for 1 to 2 days. Herbal teas and fruit infusions are best consumed the same day. Do not store carbonated drinks for long, as pressure can build up.

In summer, load the bottle with ice cubes and cold water. The vacuum insulation keeps drinks chilled for hours, making it a simple way to have ice water ready during a commute or outdoor walk.
