What is the point of a shaker bottle?

1. Core design
‌Agitation Structure‌
Built-in plastic stir balls, stainless steel metal balls, coil springs or centrifugal force design, so that the protein powder can be fully dissolved by rapid horizontal shaking (not up and down shaking) to avoid agglomeration.
Some high-end cup models use "vortex" structure or electric stirring technology to further shorten the mixing time to 5-10 seconds.

Leakproof Design‌
The cup lid has a strong sealing ability to avoid liquid spilling during violent shaking. Some products improve leakage protection through pull rings or double-layer locks.
‌
Capacity and layering
The common capacity is 300-1000ml. Choose different capacity according to your needs to meet the hydration and protein powder needs after high-intensity exercise.
Some cups are designed in layers or independent bins to facilitate carrying protein powder, pills or snacks.

2. Material and health and safety
‌Cup body material
You can choose PP material or ‌Tritan material (resistant to high temperature, anti-fall, no odor) or other ‌BPA-free plastic‌ to avoid harmful substances such as bisphenol A.
The bottom of the cup is designed to be curved or U-shaped, reducing cleaning dead corners and preventing residues from breeding bacteria and odors.
‌
Stirring ball material‌
You can choose stainless steel metal balls, which are wear-resistant and not prone to rust, improve mixing efficiency, or you can choose plastic balls, which are economical and affordable.

3. Usage skills and precautions
‌Brewing order‌
‌Add water/milk first (temperature ≤40℃), and then add protein powder to avoid absorbing water and agglomeration of the powder.
‌
Shake method‌
Shake horizontally for 10-30 seconds to reduce the generation of foam; shaking up and down can easily lead to excessive foam and affect the taste.
‌
Cleaning and maintenance‌
Rinse immediately after use to avoid residual fermentation of protein powder and produce odor‌.
Some cup types support one-click disassembly or do not require disassembly and cleaning (such as centrifugal force technology), improving convenience.

4. Additional functions and scene expansion
‌Multifunction‌
It can make milkshakes, fruit puree, foam coffee, etc. to meet the needs of breakfast meal replacement or office refreshing.
‌
Portability
Adjustable lifting ring and lightweight design, suitable for fitness, cycling, travel and other scenarios.

Summarize
