The present document describes a cap (110) for closing a container (114), the container having a neck (112) with an upper edge (118) defining a discharge opening (116). The cap comprises a lid (122) and a seal gasket (136) for sealingly engaging the neck of the container. The lid has at least one inwardly extending projection (132) for supporting the seal gasket.

A beverage container includes a hollow container with a first reservoir and a second reservoir positioned within the hollow container, the first reservoir configured to store an aqueous beverage, the second reservoir sealingly storing one or more polymer matrices that include cannabinoid compounds, the second reservoir being configured to release the one or more polymer matrices into the aqueous beverage subsequent to the second reservoir being opened, the hollow container defining an opening through which a liquid in the hollow container is allowed to egress from the hollow container. The beverage container also includes a closure sealingly and operably coupled with the opening of the hollow container, the closure operably coupled with the second reservoir such that opening of the closure initiates opening of the second reservoir, the closure sealing the opening of the hollow container. Methods of using the beverage container and preparing a beverage containing cannabinoids are also described.

A bottle cap that is an apparatus for containing heterogeneous materials, applied in the discharge direction of materials in a container, comprises: a main body coupled to a bottle neck; and a containing unit assembled inside the main body with a storage space. An activated unit is assembled in the center of the upper support unit of the main body. An activation unit for downward movement is coupled to the activated unit so that the activated unit may move downward by a separate activation unit. An opening/closing unit is coupled with the lower part of the activated unit with the above structure in order to seal an opening/closing hole of the storage space.
