Flexible closure and package including a flexible closure

A closure for a container, the closure comprising a radially extending elastomeric sealing bead that is pressed against a sealing surface of the container when coupled with the container, the closure further comprising a planar main wall, a compliant portion, and an annular flange

• the planar main wall extending radially outward from a center of the closure to the compliant portion,
• the compliant portion extending between the main wall and the annular flange, wherein the sealing bead extends radially from the compliant portion,
• the annular flange extending from the compliant portion and having a radially extending base wall, an axially extending skirt, and a lip protruding radially inwardly from the axially extending skirt,
• wherein a radial gap is defined between the lip and the container when the closure is coupled with the container,
• wherein the compliant portion comprises a first wall depending downwardly from the radially extending base wall of the annular flange, a second wall depending downwardly from the planar main wall and opposing the first wall across an annular gap, the first and second walls being interconnected by a connector wall spanning the annular gap between the first and second walls,
• wherein the elastomeric sealing bead extends radially outward from the first wall of the compliant portion, and
• wherein the main wall, compliant portion, and annular flange have a uniform wall thickness.
