A closure for a container having a container opening is provided herein. The closure includes an annular top having an inner skirt depending downwardly from an inner perimeter of the annular top and having an outer skirt depending downwardly from an outer perimeter of the annular top. An annular bottom extends radially inward from the inner skirt, and the annular bottom has defined thereon a dispensing aperture positioned adjacent to the container opening when the closure is mounted to the container. A sealing member is formed to the annular bottom for closing the dispensing aperture. The outer skirt optionally includes a hingedly flexible flap having one or more gussets dimensioned to cooperate with the anti-rotation structure of a neck finish.

What is claimed is: 1. An aseptic closure for a container having a container opening, the closure comprising: an annular top having: an outer skirt depending downwardly from an outer perimeter of the annular top and an inner skirt depending downwardly from an inner perimeter of the annular top, wherein a portion of the container adjacent the container opening is received between the outer and inner skirts, an annular bottom extending radially inward from the inner skirt, the annular bottom having defined thereon a dispensing aperture being positioned within the container opening when the closure is mounted to the container, a sealing member formed to the annular bottom for closing the dispensing aperture and a frangible line of weakness formed in a V-shape between the sealing member and dispensing aperture, wherein at least a portion of the sealing member is removable from the annular bottom at the frangible line of weakness to expose at least a portion of the dispensing aperture, and wherein the sealing member is secured to a gripping member, which when the gripping member is pulled the frangible line of weakness breaks separating the sealing member from the annular bottom; and an overclosure having: an annular base having an orifice positioned within the dispensing aperture, the annular base further having a first structure depending downwardly from an outer perimeter of the annular base to engage the outer skirt of the annular top, the annular base further having an annular ring extending upwardly about a perimeter defined around the orifice in a substantially parallel orientation to the container opening, a top hingedly connected to the base, and the top having a plug depending internally from the top and which seals against the annular ring formed by the base of the overclosure when the top is moved to a closed position and which when in the closed position the plug maintains the gripping member below the annular base, and wherein when the top is moved to an opened position at least a portion of the orifice and thus container opening being exposed whereby the sealing member can be removed through the orifice by pulling the gripping member. 2. The closure of claim 1, wherein overclosure further includes a second plug depending downwardly from the base about the orifice and positioned to engage and seal against a lateral extending portion of the inner skirt of the annular top, the second plug being oriented substantially parallel to the annular ring and having a diameter larger than a diameter of the annular ring. 3. The closure of claim 2, wherein the plug or the second plug includes surface area defining a hollow. 4. An aseptic closure for a container having a container opening extending about a first longitudinal axis, the closure comprising: an annular top having: inner and outer skirts depending downwardly from inner and outer perimeters of the annular top respectively, and the inner and outer skirts are positioned to capture a portion of the container adjacent the container opening, an annular bottom extending radially inward from the inner skirt, the annular bottom having a dispensing aperture positioned adjacent the container opening, and a removable sealing member secured to the annular bottom about the dispensing aperture by a frangible line of weakness, and wherein the removable sealing member is secured to a gripping member, which when the gripping member is pulled the frangible line of weakness breaks separating the removable sealing member from the annular bottom; and an overclosure having: an annular base having downwardly depending inner and outer structures to engage the inner and outer skirts of the annular top, respectively, the downwardly depending inner structure further defining an orifice positioned within the dispensing aperture above the removable sealing member, an annular ring extending upwardly from the annular base about the orifice, a top hingedly connected to a portion of the annular base, the top further having a first plug depending downwardly therefrom, the first plug having a diameter sized to seal against the annular ring of the overclosure when the top is moved to a closed position, and wherein when the top is moved to an opened position at least a portion of the orifice and thus container opening being exposed whereby the sealing member can be removed through the orifice by pulling the gripping member, and wherein the inner structure of the annular base is positioned to seal against the inner skirt of the annular top, the inner structure having a diameter larger than a diameter of the annular ring.
