A system and method for mixing compounds is disclosed. Accordingly to one embodiment a transfer device is provided that allows for diluent from a syringe to be introduced into a container having a first compound (e.g., powder) in a sterile manner. In second and third embodiments, systems are shown for combining and mixing first and second compounds contained in first and second containers in a sterile manner. Various dropper tips for dispensing the mixed compounds are disclosed.

An assembly and method are provided for storing and dispensing a soluble substance, such as a flavoring, into a liquid. A useful application of the subject invention includes the case where lime-flavored liquid is contained in a foam artificial lime stored in the neck of a beer bottle, attached to a beer bottle or can, or attached to the 6-pack or 12-pack carton. The artificial lime may be retrieved from the neck or a protective covering and acted upon so it diffuses the lime-flavored liquid into the beer when it is inserted into the beer bottle. Alternately, juice from the artificial lime may be squeezed into the beer, or the artificial lime may be simply retrieved and discarded. Rather than needing to buy a natural lime, cut it up and push a wedge into a beer bottle, an artificial lime, or a packaged natural lime, may be stored directly in or with the beer bottle and placed in functional contact with the beer at time of consumption.

Apparatus and methods are provided for dispensing into a liquid a soluble substance, such as a soluble flavoring. The soluble flavoring may include a lime flavoring with citric acid. It may include a cannabinoid. Alternatively, the soluble flavoring may not include citric acid or sugar. A useful application of the subject invention includes a lime flavoring held by a gelatinous elastic lime wedge. The gelatinous lime wedge may be retrieved from a protective covering and acted upon so it mixes the lime flavoring into a beverage, such as when it's inserted into a water or beer bottle or can. Rather than needing to buy and store a perishable natural lime, and cut it up, a gelatinous lime wedge holding soluble lime flavoring may be stored for an extended period of time, and placed in functional contact with water, beer, or other liquid, at time of consumption.

The present invention provides an instant-mix cap, which relates to the technical field of the bottle cap. The instant-mix cap includes a cap body and a sealing plug, and the cap body and the sealing plug enclosed to form a sealed storage chamber, a pushing part can drive an elastic part to deform and move downward under the action of an external force, and a pillar simultaneously pushes the sealing plug to move downward, so that the sealing plug is forced to be disconnected from a bottom of a cap cylinder, thereby opening the storage chamber.
