Double-Flask Bottle

Thermos, Bottle, and Shaker in One

Three items usually carried separately, combined into one. The inner glass flask holds temperature and flavor; the outer chamber works as a shaker. Two independent containers — one system.

Construction

Two Chambers Instead of Two Bottles

Dual-chamber construction: flask, shaker, and measuring compartment

Inner Glass Flask

Keeps hot and cold drinks at temperature and flavor: coffee and tea in the morning, water and electrolytes during the day.

Outer Shaker Chamber

Durable and roomy: ready for hydration and sports nutrition without a separate shaker in your bag.

Lock and Leak Protection

A safety lock and leak-proof seal built for daily carry in a backpack or car.

Powder Compartment and Scoop

The serving travels with the product itself — no disposable sachets or extra containers.

Daily Routine

One Bottle for the Whole Day

The object follows the rhythm of the day without changing shape or needing a swap: from 8 AM to 8 PM, it's the same object in hand.

8:00 AM
Morning commute: hot coffee in the glass flask.
2:00 PM
Office hours: water on the desk, blending seamlessly into the workspace.
8:00 PM
Evening workout: the mix is prepared on the spot, in the outer chamber.
Fueler: two chambers in one body
Positioning

Urban Minimalism Meets Athletic Elegance

The object lives at the intersection of function and design: commute, office, workout, and recovery — without changing form factor.

Audience
Active Adults on the Move

A broad customer base whose day moves between home, work, and the gym.

Values
Efficiency and Visual Restraint

Function over decoration: clean lines, honest scale, no unnecessary detail.

Cultural Context
Athleisure, Not a Sports Gadget

The athletic function reads through a premium everyday aesthetic — equally at home in a meeting room and on a gym bench.

Mixing & Consumables

Preparation Becomes Part of the Product

The compartment, scoop, and mixing chamber turn the bottle into a platform: it works with powders, effervescent tablets, and capsule formats. Every format is a reason to come back for more consumables.

Powders
Sports nutrition and electrolytes mix right in the outer chamber.
Tablets
Effervescent format: one chamber, one transparent dissolving process.
Retail
Product plus compatible consumables — recurring repeat purchases instead of a one-time sale.
