Abstract
Abstract A non-spill drinking cup cover is formed of two sections joined together at their center. The outer cover section can be secured to the outer periphery of a drinking cup in a conventional manner and further contains a relatively deep annular well extending around its outer periphery. Openings are provided at or near the bottom of this well, which are normally sealed by the inner cover member. The openings are unsealed by the user pressing down on the outer cover member to resiliently deform or deflect the outer cover member, thereby to move the bottom member down and away from the openings. The annular well may then be filled with fluid from the cup interior by conventionally tilting the cup, and the user may drink from any angular position on the rim of the outer annular well.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
138 words
A container closure comprising, in combination: a first cover means having peripheral connection means thereon connectable to the lip of an open container, and at least one opening extending through said first cover means; a second cover means; said second cover means being disposed adjacent said first cover means; connection means connecting said first and second cover means to one another; one of said cover means being elastically deformable normally to press area portions of said second cover means across said at least one opening, thereby normally sealing said at least one opening; said second cover means having a raised central portion extending from the top of said container closure which is adapted to be pressed by a user to shift causing elastic deformation of the deformable said cover means, thereby to open said at least one opening.
Claim 2
Dependent Claim
138 words
A container closure comprising, in combination: a first cover means having peripheral connection means thereon connectable to the lip of an open container, and at least one opening extending through said first cover means; a second cover means; said second cover means being disposed adjacent said first cover means; connection means connecting said first and second cover means to one another; one of said cover means being elastically deformable normally to press area portions of said second cover means across said at least one opening, thereby normally sealing said at least one opening; said second cover means having a raised central portion extending from the top of said container closure which is adapted to be pressed by a user to shift causing elastic deformation of the deformable said cover means, thereby to open said at least one opening.
Claim 3
Dependent Claim
34 words
The container closure of claim 1 wherein said first cover means is disposed on top of said second cover means relative to the top and bottom of a container which receives said container closure.
Claim 4
Dependent Claim
17 words
The container closure of claim 1 wherein said first cover means is a circular generally flat disk.
Claim 5
Dependent Claim
20 words
The container closure of claim 1 wherein said first and second cover means are each concentric circular generally flat disks.
Claim 6
Dependent Claim
22 words
The container closure of claim 1 wherein said at least one opening includes a plurality of openings disposed on a common diameter.
Claim 7
Dependent Claim
83 words
The container closure of claim 1, wherein said first cover means has an annular well therein; said at least one opening extending through a portion of said annular well; the outer diameter portion of said annular well communicating with the periphery of said first cover means, whereby a user can drink from any peripheral portion of said container closure when said at least one opening is open to allow fluid to flow from the interior of a container and into said annular well.
Claim 8
Dependent Claim
20 words
The container closure of claim 6 wherein said first and second cover means are each concentric circular generally flat disks.
Claim 9
Dependent Claim
22 words

Claim 10
Dependent Claim
25 words
The container closure of claim 7 wherein the bottom of said annular well is flattened; said plurality of said openings passing through said flattened bottom.
Claim 11
Dependent Claim
26 words
The container closure of claim 8 wherein said connection means consists of a snap-type connection disposed at the center of said first and second cover means.
Claim 12
Dependent Claim
38 words
The container closure of claim 8 wherein said first and second cover means are each concentric circular disks; the diameter of said second cover means being about equal to the diameter of the bottom of said annular well.
Claim 13
Dependent Claim
17 words
The container closure of claim 2, wherein it is said first cover means that is elastically deformable.
Claim 14
Dependent Claim
17 words
The container closure of claim 6, wherein it is said first cover means that is elastically deformable.
Claim 15
Dependent Claim
17 words
The container closure of claim 10, wherein it is said first cover means that is elastically deformable.
