Patent ID: 8910817

Claim:
A single use storage container, comprising: first and second closed ends; a plurality of sidewalls positioned between and engaging the first and second closed ends, the plurality of sidewalls defining, in a cross section along a longitudinal axis of the container, a triangular shape; a tab extending outwardly along an edge of the container; a rupture point proximal to the first closed end, the rupture point rupturable to provide an opening upon application of more than a predetermined threshold force by a user against said first closed end, and wherein a notch in the tab is aligned with the rupture point to enable separation along the rupture point, wherein the distance between the first closed end and the rupture point is sufficient for a user to place one of the user's thumbs thereon but is no greater than the distance between the center of the sleeve and the first closed end, so that the container can be grasped in the fist of a single hand with the rupture point being above the fist, and wherein the sleeve is configured such that, with the user grasping the sleeve in the fist with a score line being above the fist, the force solely of the user's thumb, when applied to a pressure application region of the sleeve, is sufficient to cleanly rupture the sleeve at the rupture point; the sleeve composed of a material having sufficient rigidity to resist bending during application of the threshold force by the user.
