A cover member for elongate members such as dispensing outlets for hardenable materials. The cover member defines an open end, a closed end, and an elongate wall extending between the open and closed ends. In one embodiment, a wall thickness of the cover member at the closed end is greater than a wall thickness of the cover member adjacent to the open end. In another embodiment, an inner projection is formed at the closed end. In yet another embodiment, an insert member is arranged in the closed end. In still another embodiment, the cover member comprises first and second wall layers defining the closed end and at least a portion of the elongate wall.

1. A cover member for a tubular dispensing member defining a dispensing outlet, the cover member comprising:an open end; a closed end; an elongate wall extending between the open and closed ends; whereby a wall thickness of the elongate wall adjacent to the closed end is sufficient to create an oxygen barrier adjacent to the closed end; a cross-sectional area of the cover member tapers from a maximum at a transition location along the elongate wall to a minimum at the closed end, where the transition location is spaced at least five percent of the distance along the elongate wall from the closed end to the open end; the cover member exists in a rolled configuration and an unrolled configuration; and the cover member is placed onto the dispensing member with the cover member initially in the rolled configuration by placing the closed end against the dispensing outlet of the dispensing member and then unrolling the cover member along the dispensing member to form a substantially air tight seal cover the dispensing outlet.
