Problems solved by technology

If the vessel is inadvertently tipped or dropped, the contents of the vessel may spill.
Unfortunately, many conventional lids of the third type do not adequately seal the liquid inside the vessel.
If the vessel to which one of these lids is attached is tipped or dropped, the contents may leak out of the vessel through the lid.

Embodiment Construction

[0015]Referring to FIG. 1, aspects of the present invention include a twist lid 10 for a beverage or food container 12, such as a cup, mug, thermos, tumbler, or similar storage vessel. The container 12 may be reusable or disposable. Likewise, the lid 10 may be constructed to be either reusable or disposable. For ease of illustration, the lid 10 is depicted and described as being coupled to the container 12, which is positioned in an upright orientation. However, those of ordinary skill in the art appreciate that during use, the lid 10 and the container 12 may be positioned in any orientation. Therefore, terms that relate to directions, such as top, bottom, upward, downward, and the like, have been assigned arbitrarily and are not intended to limit the invention.

[0016]The lid 10 is configured to be selectively opened and closed by a user, when the user twists a top outer ring-shaped portion 14 of the lid 10. The container 12 has a hollow interior portion 15 for storing liquid or semi...

Abstract

A lid including a positionable stopper nested inside an upper body that is nested inside a lower body. A user applies a rotational force to the upper body, which rotates about an axis of rotation relative to the lower body to translate the rotational movement of the upper body into linear movement of the stopper along the axis of rotation. The stopper is configured to move axially along the axis of rotation relative to the upper body toward and away from the vessel based upon the direction in which the upper body is rotated. When the stopper is farthest from the vessel along the axis of rotation, the stopper abuts the upper body and seals the liquid inside the vessel. When the stopper is sufficiently near the vessel, an opening is defined between the stopper and the upper body through which the contents of the vessel may exit.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is directed generally to lids for liquid storage vessels such as for beverage or food containers and more particularly to lids with movable components.[0003]2. Description of the Related Art[0004]Prior art lids are typically of one of three types. The first type is a solid unitary lid that does not include openings or apertures through which the contents of a liquid storage vessel may exit the vessel. To drink from the vessel, a user must remove the lid. The second type, which may also be of a unitary construction, includes one or more unobstructed apertures through which the liquid may exit the vessel. In the second type, the apertures are always open. If the vessel is inadvertently tipped or dropped, the contents of the vessel may spill. The third type of lid includes one or more apertures through which the liquid may exit the vessel and a means for selectively opening and closing the apertures. ...
