[0036]
[0037] In some embodiments, the multipurpose membrane 100 comprises a first layer 110 and a second layer 120. In some embodiments, the first layer 110 may have a first perimeter 111 defining a first shape, and the second layer 120 may have a second perimeter 121 defining a second shape. In some embodiments, the first shape and the second shape are the same shape (e.g., both circles, squares, triangles, or irregular shape), while in other embodiments, the first shape and the second shape are different.
[0038] In some embodiments, the first perimeter 111 is larger than the second perimeter 121 corresponding to the first shape being larger than the second shape, while in some embodiments the first perimeter 111 and the second perimeter 121 may be equal (i.e., the first layer 110 and the second layer 120 are the same size). In some embodiments, the first layer 110 and the second layer 120 may form concentric shapes, while in other embodiments the first layer 110 and the second layer 120 may be coaxial shapes.
[0039] In some embodiments, the first layer 110 and the second layer 120 of the membrane 100 may be separable from one another. The first layer 110 may define a first line of weakness 112 disposed inward of the first perimeter 111. The first line of weakness 112 may take any form which may ease breaking the layer for example, in some embodiments, the first line of weakness 112 may extend partially through the first layer 110, while in other embodiments, the first line of weakness 112 may define a series of perforations through the first layer 110. In still other embodiments, the line of weakness 112 may comprise a throughcut through the first layer 110 that circumscribes the majority of the desired opening.
[0040]
[0041] The flap 116 may be circular, triangular, or other shape, in some embodiments, the shape of the flap 116 may correspond to the product to be dispensed. In some embodiments, the first line of weakness 112 may be concentric or coaxial with the first perimeter 111, while in other embodiments, the first line of weakness 112 may be eccentric with respect to the first perimeter 111. In some embodiments, the flap 116 may be the same shape as the first layer 110, while in other embodiment the flap 116 may define a different shape than the first layer 110.
[0042] In some embodiments, the flap 116 may be removable from the first layer 100. In some embodiments, the flap 116 may include a pull tab 114. In an embodiment, the pull tab is defined by a portion 112a of the first line of weakness 112 and a groove or crease 113 formed within the first layer 100. In some embodiments, the crease 113 may be formed along a chord of the flap 116, wherein the chord is a line segment connecting two end points of a perimeter that does not pass through the center of the shape. In some embodiments, the portion 112a of the first line of weakness 112 may be a throughcut of the first layer such that the pull tab 114 is moveable from the peripheral area 115 of the first layer 110 upon formation of the crease 113.
[0043] In some embodiments, the pull tab 114 may extend out of the plane of the first layer 110 such that the pull tab 114 is easily graspable, for example, folded back upon itself. The pull tab 114 may be maneuvered to rupture the first line of weakness 112 or hinge 112b to separate the flap 116 from the peripheral area 115. In some embodiments, the first line of weakness 112 may form a closed shape such that the pull tab 114 and flap 116 may be detached from the peripheral area 115 and may be removed from the first layer 110, and the membrane 100 completely.
[0044] In some embodiments, the flap 116 may remain attached to the peripheral area 115 by the hinge 112b formed within the first line of weakness 112. In some embodiments, the hinge 112b may be formed along the first line of weakness 112 opposite the portion 112a defining the pull tab 114, while in other embodiments, the hinge 112b may be formed at any point along the first line of weakness 112. In some embodiments, the hinge 112b may be sized and configured such that the flap 116 is not easily severable from the peripheral area 115 when the pull tab 114 is lifted.
[0045] The hinge 112b may allow the flap 116 to provide access to the second layer 120, and thereby in some embodiments, access to the product within the container system. In this embodiment, the flap 116 may be removed from and replaced on the second layer 120. In some embodiments, the bottom surface of the flap 116 or the top surface of the second layer 120 may be patterned with a pressure sensitive adhesive. The pressure sensitive adhesive may retain the seal of the membrane 100 when the flap 116 is replaced on the second layer 120 within the plane of the membrane 100.
[0046] In some embodiments, the first line of weakness 112 may be configured as a tamper evident feature. For example, in an embodiment, the first line of weakness 112 may rupture as the flap 116 is removed. Upon removal, or first opening the flap 116 may be removed, or configured such that the flap 116 will not reseal in the exact location to align with the peripheral area 115, such that the first line of weakness 112 is visibly shifted.
[0047] In some embodiments, the pull tab 114 may be formed within the first layer 110 prior to application of the second layer 120. After formation of the membrane 100, the second layer 120 may be accessible by rupturing the first line of weakness 112 by maneuvering the pull tab 114.

[0052] The second layer 120 may define a peripheral zone 125 extending between the second perimeter 121 and the second inner line of weakness 122. In some embodiments, an adhesive may be patterned applied to the top surface of the second layer 120 within the peripheral zone 125. In some embodiments, the adhesive may be a pressure sensitive adhesive such that the flap 116 may be reseal to the peripheral zone 125 after an initial opening.
[0053] The second layer 120 may define a third diameter D.sub.3 extending across the second perimeter 121, and the second line of weakness 122 may define a fourth diameter D.sub.4. The third diameter D.sub.3 may be smaller than the fourth diameter D.sub.4. In some embodiments, the third diameter D.sub.3 of the second layer 120 is smaller than the first diameter D.sub.1 of the first layer 110, while in some embodiments, the third diameter D.sub.3 is equivalent to the first diameter D.sub.1. In some embodiments, the third diameter D.sub.3 is larger than the second diameter D.sub.2 such that when the pull tab 114 is maneuvered to fracture or open the first line of weakness 112, the second layer 120 remains otherwise adhered to the first layer 110.
[0054] In some embodiments, the second layer 120 may have one or more openings 124. In an embodiment, the opening 124 may be formed within the central portion 126 of the second layer 120. In some embodiments, the opening 124 may be positioned inward of the second line of weakness 122 (e.g., within the central portion 126), while in other embodiments, the opening 124 may be positioned external thereto (e.g., within the peripheral zone 125). The shape and the size of the opening 124 may correspond to the product to be dispensed from the container.
[0055] In some embodiments, the opening 124 may be a plurality of openings within the central portion 126 (see, e.g.,
[0056] In some embodiments, the central portion 126 may be removed to allow larger products and/or a greater flow of products to be dispensed through the membrane 100. In some embodiments, the central portion 126 may be removed by fracturing the second line of weakness 122. In some embodiments, a second hinge 122b may disrupt the second line of weakness 122. The second hinge 122b, may allow the central portion 126 to be maneuvered to allow a greater flow of product from the container, and repositioned in line with the peripheral area 125 to return to the lower flow of product from the container. In some embodiments, the second line of weakness 122 may be formed such that after a fracture, the central portion 126 may readhere to the second layer 120 along the second line of weakness 122.
[0057] In some embodiments, the membrane 100 may be configured such that the second layer 120 is product facing. In some embodiments, the second layer 120 may be a single ply layer, while in other embodiments, the second layer 110 may comprise multiple paper or cardboard layers. In some embodiments, the second layer 120 may include a barrier layer. The second layer 120 may be food safe.
