Abstract:
1. An adjustable diameter drinking vessel sleeve, comprising: a sleeve side wall sheet having a first side wall sheet end and a second side wall sheet end and being coiled into a tubular sleeve configuration having a sleeve circumference, such that said first side wall sheet end is radially spaced inwardly from said second side wall sheet end, and comprising an adjustment lever structure pivotally interconnecting said first and second side wall sheet ends and extending radially inwardly from said first side wall sheet end to define a lever tab portion; such that pivoting said lever tab portion toward said first side wall sheet end circumferentially spaces said first side wall sheet end and said second side wall sheet end apart from each other to increase the sleeve circumference and thereby to place said sleeve in a larger diameter mode to receive a larger diameter drinking vessel, and such that pivoting said lever structure toward said second side wall causes said second side wall end to overlap said first side wall end to decrease the sleeve circumference and thereby place said sleeve in a smaller diameter mode to receive a smaller diameter drinking vessel.
