Lever-Action Seal for Detaching a Frozen Drink Maker's Mixing Cup
This patent describes a frozen drink maker that uses a lever and a flexible seal to easily attach and detach the mixing cup from the main machine.
Original patent title: “Drink maker with detachably connectable mixing vessel”
This patent describes a frozen drink maker that uses a lever and a flexible seal to easily attach and detach the mixing cup from the main machine. Granted in 2026.
Coverage
What does this patent actually cover?
This patent describes a frozen drink maker designed for easy attachment and detachment of its mixing vessel. The machine includes a main housing, which has an upper section, and a mixing vessel where the drink ingredients are blended. A flexible seal sits between the upper housing section and the mixing vessel. The key feature is a lever on the housing that moves. When the lever is in a "coupled position," it securely connects the mixing vessel to the upper housing, with the flexible seal ensuring a leak-proof connection. Moving the lever to an "uncoupled position" releases the mixing vessel. For example, to make a smoothie, you would fill the mixing vessel, place it on the drink maker, push the lever to lock and seal it, blend your drink, then pull the lever to quickly remove the vessel.
The gap
What does this patent NOT cover?
- Does not cover drink makers where the mixing vessel is permanently attached to the housing.
- Does not cover attachment mechanisms that do not involve a movable lever to couple and uncouple the vessel.
- Does not cover systems where a flexible seal is not present between the upper housing section and the mixing vessel.
- Does not cover drink makers that use a twist-lock or magnetic attachment system without a distinct lever action.
- Does not cover appliances where the seal is located elsewhere, not specifically between the upper housing and the mixing vessel.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
