This is combination of a lid, a doser and a processor. The Gizmo is seen in action in the large bottle in the scan of the company's website below. The orange colour has been introduced from the lid and is being mixed into the contents of the bottle.

The apparently oversized lid on the bottle contains material and a gas, normally carbon dioxide as well as a concentrate. When the lid is twisted a seal is broken and the gas forces the concentrate into the bottle, mixing the concentrate into the contents.
As well as beverages, Gizmo believes there are opportunities in chemical, household liquids, cosmetics, agricultural chemicals and pharmaceuticals.
Although there might be a fun value in mixing colour and flavour into your carbonated soft drink, I believe the cost and complexity of the Gizmo Closure is better suited to applications where keeping the additives and base separate until consumption has value. For instance an antioxidant added to a milk drink might be unstable during storage either reducing functionality or resulting in off flavours. This would be an ideal application where the antioxidant is stored in an air and light tight cap, reducing the chance of deterioration and extending the shelf life.
As an ex brewer, maybe this is the magic alcoholic beer concentrate package. The freeze evaporated concentrate could be stored in the cap of a cap on a bottle of soda water.
Possibly there is an opportunity to sell the caps separately for personalised modification of beverages or the simultaneous carbonation and flavoring of tap water which would reduce packaging, transport and storage costs for flavored bottled water.
This is a paper looking at the potential of a less used Nigerian traditional drink produced from Tamarind
The paper looks at different recipes based on the level of the added Ginger, Clove and Pepper. It presents taste and analytical results along with traditional and improved process descriptions.
This article in Food Production Daily reports on a double can able to hold two different drinks and a resealable can.
The former is merely a patent while the latter is a design which has been developed with Coca Cola and should be in the market soon if not already launched.
These developments add to the popularity of the can which relies on its light weight, stackability, ease of cooling, ease of opening, robustmess and tamper evident design.
