Abstract

Abstract An adjustable lid for a pan including: (a) a central circular member and an outer annulus, (b) annular ribbing reinforcing said lid and engaging said pan against dislodgement, (c) the bottom of the lid sloping to a location medial of the edge and center of the central member so that condensation will tend to drip from that location into the pan, and (d) securing means between the central member and annulus including undercut slots on one and ears on the other latching by relative rotation of the central member and annulus, and manually operable spring clip means holding the members secured.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 296 words
An adjustable lid for a cooking utensil or the like, comprising: (a) a circular central member and at least one annulus having an inner diameter close to the outer diameter of said central member, together to form a cover for such utensil, (b) securing means between said central member and said annulus including a plurality of slots in one and a plurality of ears on the other fitting in said slots, said ears locking in said slots by a turning movement of said annulus relative to said central member to hold said annulus and said central member generally coplanar, (c) said central member being generally planar and said annulus being generally planar and said annulus having an upright return bend near its inner margin and a ledge leading from said return bend to form a seat for the peripheral edge of said central member in said annulus, and (d) said slots being formed by upwardly open cuts in said return bend that terminate in undercuts at one end and the outer edge of said central member terminating in an upright flange and said ears being formed as continuations of said flange that are cut and struck out with an inboard web and an ear portion leading tangentially from said web, said ears engaging in said slots by engaging said webs in said upwardly open cuts and then advancing said webs into said undercuts, with said ear portion outlying said undercuts, at least one spring clip secured at one end to the top of said annulus and having a manually operable tab on the other end and said spring clip making a return bend between said ends, said bend frictionally engaging one of said ears to latch the same in the undercut end of the associated slot.

An adjustable lid for a cooking utensil or the like, comprising: (a) a circular central member and at least one annulus having an inner diameter close to the outer diameter of said central member, together to form a cover for such utensil, (b) securing means between said central member and said annulus including a plurality of slots in one and a plurality of ears on the other fitting in said slots, said ears locking in said slots by a turning movement of said annulus relative to said central member to hold said annulus and said central member generally coplanar, (c) said central member being generally planar and said annulus being generally planar and said annulus having an upright return bend near its inner margin and a ledge leading from said return bend to form a seat for the peripheral edge of said central member in said annulus, and (d) said slots being formed by upwardly open cuts in said return bend that terminate in undercuts at one end and the outer edge of said central member terminating in an upright flange and said ears being formed as continuations of said flange that are cut and struck out with an inboard web and an ear portion leading tangentially from said web, said ears engaging in said slots by engaging said webs in said upwardly open cuts and then advancing said webs into said undercuts, with said ear portion outlying said undercuts, at least one spring clip secured at one end to the top of said annulus and having a manually operable tab on the other end and said spring clip making a return bend between said ends, said bend frictionally engaging one of said ears to latch the same in the undercut end of the associated slot.
Claim 3
Dependent Claim 124 words
The subject matter of claim 1 in which said central member has a handle secured centrally to its upper surface, said central member having annular reinforcing ribs formed therein producing annular upper groove and annular lower protrusion that help center the lid on such utensil or the like against dislodgement, the lower surface of said central member downwardly sloping from its center and from its periphery to a medial annular location so that condensation on the lower surface of said central member will tend to flow to said annular location and drip from there into such pan or the like, and the lower surface of said annulus inwardly downwardly sloping to direct condensation inwardly and having reinforcing ribs like those in said central member.
