Personal blender

A blender assembly including:

• a blender hub having a plurality of first guide elements;
• a blender vessel having a rim, the blender vessel further having a plurality of second guide elements that each cooperate with a respective one of the first guide elements for forming a coupled and a sealed engagement to the blender hub;
• wherein, releasing the coupling, the first and second guide elements cooperate to provide a two-stage release;
• a first stage of the release breaking the sealed engagement, and maintaining a loose coupled engagement, between the blender hub and the blender vessel, and a second stage of the release, subsequent to the first stage of the release, releasing the coupled engagement between the blender hub and the blender vessel;
• wherein each of the first guide elements and the second guide elements comprise at least two thread portions that are offset to provide a two-stage release;
• and
• wherein sizing of at least one of an outer thread portion is greater than a spacing between the outer thread portion and an inner thread portion.

• wherein the first guide element of the blender hub includes a hub thread portion having a lead thread segment, a sealing thread segment and an intermediate thread segment;
• and the second guide elements comprises at least one vessel thread portion that, upon respective rotation between the blender vessel and blender hub, can sequentially engages each segment of the hub thread portion;
• and
• wherein the intermediate thread segment has a thread pitch that is greater than that of the lead thread segment.

• a first stage of the release breaking the sealed engagement, and maintaining a loose coupled engagement, between the blender hub and the blender vessel to at least aid in partly dissipating pressure within the blender vessel to outside the blender vessel;
• and a second stage of the release, subsequent to the first stage of the release, releasing the coupled engagement between the blender hub and the blender vessel,
• wherein each of the second guide elements include at least two thread segments that are offset in a direction of engagement to thereby provide the two-stage release.
