Container cap with finger-openable, reclosable closure
First Claim
1. A cap for a container mouth comprising in combination:
- a transversely extending platform portion having upper and lower opposed faces and having a depression relative to said upper face defined therein that extends generally across said platform portion, said depression having a pair of laterally spaced, generally opposed side walls and a bottom wall extending between said side walls;
a generally cylindrical, peripheral flange portion extending downwardly from said lower face, said flange portion defining circumferential surface portions whereby said flange portion is engageable with peripheral portions of said container mouth;
a closure plate having top and bottom surface portions, proximal and distal opposite end portions, and a pair of laterally spaced, opposed lateral wall portions, said closure plate being generally receivable within and between said depression side walls with each of said lateral wall portions being adjacent to a different one of said side walls, said proximal end portion having first hinge means that pivotably associates said closure plate with said platform portion, whereby said closure plate is pivotable relative to said depression;
said depression having an aperture defined therethrough that is located in spaced, adjacent, radially interior relationship relative to said flange, and said bottom surface portions of said closure plate having an outstanding stopper means associated therewith, the interrelationship between said aperture and said stopper means being such that, when said closure plate is pivoted so that said bottom surface portion is adjacent said depression bottom wall, said stopper means closes said aperture; and
a pull ring pivotally connected to said distal end portion, including associated hinge means, whereby, when said pull ring is finger engaged, said closure plate is pivoted upwardly away from said depression and said stopper means is separated from said aperture.

Abstract
A removable and reusable cap for a container is provided. The cap has a platform portion and peripherally associated upstanding and downwardly extending portions, and a depression is defined across the platform portion. In the depression, a dispensing aperture and preferably a vent are defined which are opened and closed by a closure plate that is received within the depression and that has a proximal end which is pivotably associated with the depression. The distal end of the closure plate is pivotally associated with a pull ring that is biased into association with the closure plate and that is nestably received in the closure plate, but that has a finger associatable apex region. When the pull ring is pivoted upwardly, the closure plate is pivoted and the dispensing aperture and vent are opened, preferably the vent before the dispensing aperture.

20. A reusable container cap for a container mouth comprising in combination:
-
a unitarily formed base comprising a transversely extending platform portion having a top surface, peripheral, upstanding side wall portions about said platform portion, and peripheral downturned, circumferentially extending, threaded side wall portions about said platform portion, said platform portion being inclined relative to said side wall portions, thereby defining a well between said top surface and an adjacent region of said upstanding side wall portions, said platform portion also having a depression defined in said top surface that extends generally transversely thereacross from said well; said depression having a bottom and opposed side walls, an aperture defined therein radially interiorly adjacent said downturned side wall portions and a vent defined therein in radially inwardly spaced relationship relative to said aperture; a closure plate having upper and lower opposed surface portions, proximal and distal opposite end portions, and opposite lateral side portions which each fits in said depression adjacent a different one of said opposed side walls, said proximal end portions being associated with first hinge means enabling pivotal movements of said closure plate in said depression, and said lower surface portions having first and second stopper means positioned and adapted to close said aperture and said vent, respectively, when said lower surface portions are adjacent said bottom; and a pull ring pivotally associated by second hinge means to said distal end portion and having spring means yieldingly biasing said pull ring into a flattened association with said upper surface portion and stop means limiting the maximum angle of pivotal opening of said pull ring relative to said closure plate; said upper surface portion including depressed portions adapted to nestably receive adjacent portions of said pull ring and to permit access of a finger adjacent said pull ring; whereby elevating said pull ring by said finger relative to said upper surface separates said lower surface portion from said bottom and opens said aperture and said vent.
