Claim:
A hollow container suitable for containing fluid or granules, said container comprising a body and a neck, and having an opening in the neck defined by a rim through which contents of the container may flow, said container optionally having an external thread or other mechanical detent on the neck suitably adapted to receive a cap with internal threads or other mechanical means for retaining the cap in place on the neck of the container, and a removable sealing device, said device comprised of a membranous seal, comprised of a flexible, frangible material having a reasonably low coefficient of friction, said membranous seal having a sealing component and a tab component, with the sealing component suitably shaped to completely cover the opening in the neck of the container and the rim of the opening, and with the tab component having a substantially elongated rectangular shape, with an attachment end and a gripping end located opposite the attachment end, and with a first edge and a second edge opposite the first edge, the attachment end of the tab component attached to and integrated with the sealing component such that the tab component is oriented substantially perpendicular to the sealing component, and the gripping end of the tab component having a greater width than the width of the remainder of the tab component or having any other suitable shape so as to make the tab component convenient to grasp, and a sleeve, comprised of a flexible material having a reasonably low coefficient of friction, said sleeve having openings at either end and being suitably adapted to be positioned over and around the neck of the container such that the sleeve fits snugly about the neck of the container and below the external thread or other mechanical detent on the neck; whereby the tab component is folded back upon the sealing component, then folded downward along the neck of the container and over the external thread or other mechanical detent on the neck, such that the tab component is positioned between the sleeve and the neck of the container with the gripping end of the tab component extending from the lower opening of the sleeve.
