SYSTEM AND METHOD FOR BLENDING CONTAINMENT ASSEMBLY
A blending containment assembly includes a cover having a first aperture and a cup seal connected to the cover. The cup seal is a flexible material having a second aperture. The cover and the cup seal are configured to receive a spindle of a blending assembly in the first aperture and the second aperture. The cover and the cup seal are movable to engage a cup to create a seal between an inside of the cup and an outside of the cup.
1 . A blending containment assembly comprising:
a cover having a first aperture; and
a cup seal connected to the cover, the cup seal being a flexible material having a second aperture, the cover and the cup seal configured to receive a spindle of a blending assembly in said first aperture and said second aperture, and the cover and the cup seal movable to engage a cup to create a seal between an inside of the cup and an outside of the cup.
2 . The blending containment assembly of claim 1 , wherein the cup seal has an engagement surface to contact the cup that is angled so that the engagement surface tapers inward.
3 . The blending containment assembly of claim 1 , wherein the cover forms a vent therein.
4 . The blending containment assembly of claim 1 , wherein the cup seal has a side wall extending from a center wall that create an overflow volume when engaged with the cup, and wherein the overflow volume is above the cup.
5 . The blending containment assembly of claim 4 , wherein the cover forms a vent through the cover from the overflow volume to outside of the cup, the cup seal and the cover.
6 . The blending containment assembly of claim 1 , wherein the cup seal is removable from the cover.
7 . The blending containment assembly of claim 1 , wherein the cup seal is elastomer.
8 . The blending containment assembly of claim 1 , further comprising a blender motor with spindle which drives a blade, wherein the blender motor is attached to a blender bracket which is connected to a linear actuator which allows vertical movement of the blender bracket and the blender motor with the spindle and the blade, further comprising at least one guide rod having a first end attached to the blender bracket via a spring, and wherein the guide rod has a second end opposite the first end that is fixed to the cover.
9 . The blending containment assembly of claim 8 , wherein the spring generates a force to hold the cover against a blade guard surrounding the blade in an initial position.
10 . The blending containment assembly of claim 8 , wherein the cover moves with the blender bracket prior to engagement of the cup seal with the cup.
11 . The blending containment assembly of claim 8 , wherein the spring applies a force to the cup that increases as the spindle and the blade extend into the cup.
12 . The blending containment assembly of claim 8 , wherein the cup seal has an engagement surface to contact the cup, and wherein the engagement surface that engages the cup prior to the blade displacing ingredients in the cup.
13 . The blending containment assembly of claim 1 , wherein the cup seal is 30 Shore A liquid silicone compression molded into shape.
14 . The blending containment assembly of claim 1 , wherein the cup seal has tubular shape.
15 . The blending containment assembly of claim 1 , wherein the cup seal has an engagement surface that contacts an inner surface of the cup.
16 . The blending containment assembly of claim 1 , wherein the cup seal is a flexible membrane that deforms to conform to a shape of the cup.
