Independent Claim
109 words
A blank adapted to be folded into a closure for enclosing a rectangular flange surrounding the opening of a container, said blank comprising: a rectangular central panel and hingedly attached to each of the four sides of said central panel along a scored line, a side panel wherein the length of the side panel is equal to the side of the central panel to which it is attached and wherein the width of the side panel is sufficient to overlap the adjacent side panels to form a sealable surface with the adjacent side panel surfaces that are contiguous thereto when said side panels are folded against said central panel.
Claim 2
Dependent Claim

A blank adapted to be folded into a closure for enclosing a rectangular flange surrounding the opening of a container, said blank comprising: a rectangular central panel and hingedly attached to each of the four sides of said central panel along a scored line, a side panel wherein the length of the side panel is equal to the side of the central panel to which it is attached and wherein the width of the side panel is sufficient to overlap the adjacent side panels to form a sealable surface with the adjacent side panel surfaces that are contiguous thereto when said side panels are folded against said central panel.
Claim 3
Dependent Claim
56 words
A blank of claim 1 wherein a first side panel and a second and a third side panel adjacent thereto have an amount of pressure sensitive adhesive sufficient to form a seal applied on each of the four surfaces that are contiguously paired when said side panels are overlapped by being folded against said central panel.
