Turn Any Water Bottle Into a Camel Pack — My Next Product Idea

After every race or marathon, I always grab a water or Gatorade bottle — but I hate carrying it around. That’s where this product idea comes in:
A universal cap that fits standard water and Gatorade bottles, turning them into a camel pack-style hydration system.

The Concept

• A custom cap that screws onto most disposable water and sports drink bottles.
• Equipped with a hose and bite valve, just like a camel pack.
• Perfect for post-race hydration without needing to carry or juggle your bottle.

Development & Cost

• Prototype Cost: Around $30 to produce.
• Tooling/Manufacturing Setup: Estimated at $2000 for the initial mold.
• Production Cost: About $1 per unit.
• Retail Price: Planning to sell at $10 each — affordable, reusable, and super convenient.
