Container lid and valve

摘要

A lid configured for use with a fluid container includes a body member and a valve. The body member includes a central body that extends to an outer periphery configured to couple to a rim of a fluid container. The body member defines an aperture therethrough and has top and bottom surfaces. The valve has a first portion directly secured to the bottom surface and a second portion that extends from the first portion. The second portion includes a protuberance and is movable relative to the first portion between free and depressed states in response to deflection of at least a portion of the central body relative to the outer periphery. The protuberance is configured for sealed engagement with the aperture while the second portion is in the free state and is spaced from the aperture while the second portion is in the depressed state.

主权项

1. A lid configured for use with a cooperative fluid container having a rim, the lid comprising:
a body member formed of a deformable plastic material, the body member including a central body that extends to an outer periphery having a circumferential lip, the lip being configured to sealable couple the lid to the rim of the fluid container upon urging of the lip over the rim, the body member defining an aperture therethrough adjacent the outer periphery, the central body having a top surface and a bottom surface and, being deformable and downwardly deflectable upon the application of manual pressure to the top surface of the central body; and a valve having a first portion directly secured to the bottom surface of the body member and a second portion distinct from and extending from the first portion, the second portion including a contact region adjacent the bottom surface of the central body and a sealing portion, the valve having a free state occurring in the absence of downward manual pressure applied to the top surface of the central body in which the sealing portion of the second portion occludes and thereby substantially seals the aperture, and the valve having a depressed state occurring in response to the application of downward manual pressure applied to the top surface of the central body and resulting downward deflection of the central body in which the bottom surface of the central body abuts the contact region of the second portion to urge the sealing portion downward and away from the aperture so that the sealing portion is spaced from and does not occlude the aperture.
