Patent attributes
Disclosed are embodiments of containers, caps, sealing assemblies, and associated components. In one embodiments, a sealing assembly can include an expander actuator operatively coupled to an expander, which expander is operatively coupled to a seal. In a locking state, the expander actuator is configured to cause the expander to expand horizontally against the seal. The expansion of the seal against a shoulder and/or a neck of a container provides a locking, leak-proof seal. In an opening state, the expander is configured to provide an upward movement of the expander actuator, allowing the expander to return to its unexpanded form, which in turn causes the seal to return to its unexpanded form. When the seal is in its unexpanded form, the sealing assembly (along with an associated cap) can be pulled away from the container body.
