Dual Bottle: A Two-Compartment Bottle for Two Liquids at Once

Carrying two drinks without carrying two bottles

Dual Bottle lets a user carry two different liquids at once in a single, portable unit, without the bulk or hassle of carrying two separate bottles.

The core challenge was enabling that without mixing, while keeping the bottle compact, easy to use, and ready to manufacture at volume through injection molding.

What made this project hard

Two compartments, one bottle

A two-part system that attaches and detaches easily without leaking between chambers.

Leak-proof sealing

A sealing mechanism reliable enough for daily, on-the-go use.

Balanced handling

Weight distribution and grip that stay comfortable even with two full chambers.

From concept to a manufacture-ready bottle

Engineered for production from the first sketch.

01

Concept Development

A two-part compartment system engineered to attach and detach easily.

02

Sealing Design

Leak-proof mechanisms incorporated between compartments.

03

Ergonomics

Weight distribution and handling balanced across two chambers.

04

DFM for Molding

Full technical detail and assembly guidance prepared for production.

An attachable, detachable two-part system

The bottle was engineered around a two-part compartment system that can be easily attached or detached, the core mechanism the rest of the design was built around.

Dual Bottle sealing mechanism detail

Leak-proof sealing between compartments

Sealing mechanisms were incorporated to keep the two liquids fully separated, holding up to daily handling rather than just a bench test.

Balanced for everyday carry

Weight distribution and grip were tuned so the bottle stays comfortable to hold and use even when both compartments are full.
