Powder Storage Cap with Foil Seal | Beverage Bottle Cap

Foil-Sealed Powder Storage Cap for Beverage Bottles

This powder storage cap features an integrated chamber that keeps dry powder separately packaged above the liquid until the product is ready to use. The powder chamber is protected by a foil membrane, allowing the dry ingredient and beverage to remain physically separated during storage and transportation.

To use, simply open the bottle, flip the powder chamber, peel off the foil seal and allow the powder to pour directly into the bottle. Close the bottle and shake to mix the ingredients with the liquid.

Separate Dry Powder from Liquid Until Use

Instead of premixing the powder with the beverage, the dry ingredient is stored inside the cap and released only when the consumer is ready to use the product.

1. Open and remove the outer bottle cap.
2. Flip the powder storage chamber over.
3. Peel off the foil membrane.
4. Allow the stored powder to pour into the bottle.
