Claim 3

The package of claim 1 wherein said lid has a depending annular rib on its undersurface, said rib forming a plug seal with said mouth.

Claim 4

The package of claim 1 wherein said lid when in a closed position is biased toward said top flange and facially engages said top flange.

Claim 5

The package of claim 1 further including a tearable disk which blocks access to the mouth of said container unless torn.

Claim 6

Claim 9

The package of claim 1 wherein said skirt has a top edge which projects above said top flange, and said lid fits within said top edge.

Claim 10

The package of claim 8 wherein said lid is connected to said top edge by frangible bridges.

Claim 11

The package of claim 9 further including a planar tearable seal which is adhered to said lid and said top edge of said skirt, across said bridges.

Claim 12

A package comprising a wide mouth container and a closure for the mouth of the container, said container having an integral annular top flange which extends outwardly around said mouth, said closure having a top which covers the mouth of said container, the major portion of the area of said top comprising an openable lid which is hinged along a line adjacent the perimeter of said top to a minor portion of the area of said top, a clamp depending from said minor portion and having means gripping a minor arcuate portion of said flange to secure said closure to said container, said clamp being C-shaped in vertical section with top and bottom surfaces which grip said flange between them, said clamp being engageable with said flange to secure said closure to said container by moving said clamp laterally in the plane of said flange, and a skirt depending from the perimeter of said lid below said flange, said skirt having snap means engageable with said flange to hold said lid closed.
