Patent ID: 8910828

Claim:
A method for storing and dispensing a flowable material without bimanual synergy, the method comprising the steps of: forming a sleeve of triangular shape from a single sheet of material; sealing the longitudinal edges of the sheet to form a longitudinal seam along one edge of the sleeve; sealing a first end of the sleeve to form a flattened base; filling the sleeve with a flowable material; sealing a second end to contain the flowable material within the sleeve; providing a score on the sleeve, the score proximal to the first end and the score rupturable to provide an opening upon application of more than a predetermined threshold force by a user to the longitudinal seam of the sleeve in a pressure application region of the sleeve between the score and the first end, wherein the threshold force is between 1 and 100 Newtons, wherein the distance between the first end and the score is sufficient for the 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 end, so that the sleeve can be grasped in the fist of a single hand with the score being above the fist, wherein the sleeve is configured such that, with the user grasping the sleeve in the fist with the score being above the fist and the fist providing an opposing force to that provided by the thumb of the user, the force solely of the user's thumb, when applied to the pressure application region of the sleeve, is sufficient to cleanly rupture the sleeve at the score, and wherein the sleeve is made of material having suitable rigidity to resist bending during application of the threshold force.
