Caps and adapters for containers
Abstract:
A cap may include a top and a sidewall depending from the top. A plug may also extend from the top, spaced from the sidewall. Threads are formed either on an internal surface of the sidewall, i.e., generally facing the plug, or on an external surface of the plug, i.e., generally facing the sidewall. The spacing between the sidewall and the plug generally defines a receptacle configured for receiving an open end of a container. The sidewall and the plug may be angled relative to each other, such that the receptacle has a cross-section that is generally V-shaped.
