A closure tear handle which prevents damage to the closure tear skirt under large application forces when the closure is applied to the bottle; this invention also provides a tear skirt which is easier for consumers to remove. A weak region is placed at the base of the intersection of the tear handle and the wall of the tear skirt. This weak region of the closure is designed such that upon contact with the neck finish of a bottle, which puts the tear skirt into tension, it attracts the tensile forces and relieves stress from the adjacent weak point of the closure tear skirt to prevent damage to this area that would be offensive to consumers and result in wasted product.

[ What is claimed is:] [1.] A plastic closure for a bottle, the closure comprising:(a) a capping portion;(b) an annular tear skirt attached to the capping portion by an annular line of weakness formed into the closure, the tear skirt having a lower peripheral edge;(c) a starter line of weakness form

[ What is claimed is:] [1.] A plastic closure for a bottle, the closure comprising:(a) a capping portion;(b) an annular tear skirt attached to the capping portion by an annular line of weakness formed into the closure, the tear skirt having a lower peripheral edge;(c) a starter line of weakness formed into the tear skirt from the annular line of weakness to the lower peripheral edge;(d) a tear tab attached to the tear skirt proximate to the starter line of weakness, such that pulling on the tear tab will fracture the starter line of weakness; and(e) a single relief recess proximate to the point of attachment of the tear tab to the tear skirt and proximate to the lower peripheral edge, said relief recess being not longitudinally aligned with said starter line of weakness, such that the relief recess acts to reduce the amount of tensile forces exerted on the lower peripheral edge, and therefore on the starter line of weakness, when the closure is applied to the bottle.
