Lever-Enhanced Lid for Beverage Containers

Traditional twist-on lids for beverage containers, such as those used by Yeti or Stanley, can become difficult to open due to pressure differentials, residue build-up, or limited grip strength. Existing solutions involve external tools, which are not always convenient or safe. There is a need for a lid that integrates a leverage tool to assist in opening the lid effortlessly. Furthermore, there is a need for a retrofit solution that allows existing lids to be equipped with such a leverage tool.

The present invention addresses the above needs by providing a lid with a built-in deployable lever. This lever can be deployed to act as a mechanical advantage tool, allowing users to easily open the lid without requiring external devices or excessive force. Additionally, the invention includes a deployable lever that can be added to existing lids, enhancing their functionality.

A few of the preferred embodiments have been illustrated and described in detail. It is understood, however, that numerous modifications can be made without departing from the invention's scope as claimed. Those skilled in the art will recognize that many variations and substitutions may be made, qualifying as equivalents under the patent claims. The specific embodiments described herein are intended only to exemplify the invention and should not be seen as limiting its spirit or scope.

In the figures, not every element is assigned a reference number. Directional terms such as “forward,” “rearward,” “upper,” “lower,” “bottom,” “top,” and “side” are used to describe the orientation of the components as depicted in the drawings. Those skilled in the art will understand that these orientations may vary during actual use of the invention and are not intended to be limiting.

The closed position is defined as the state in which the leveris positioned out of the way and not in use. In this embodiment, the deployable leveris coupled to the lid via a hinge, functioning as a folding lever. Frictional forces maintain the leverin the closed position, preventing accidental deployment into the open position. This configuration represents the typical usage scenario, where the leverremains folded and unobtrusive. This embodiment features a passagefor drinking water through the lid. Although not included, other embodiments exist that incorporate stoppers, straws, or other features without escaping the scope of the claims.

The leverpivots on the hinge, extending away from the lid until it makes contact with the lid, thereby preventing further pivoting. In this open position, the leveris designed to provide mechanical advantage, enabling the user to grasp it to facilitate the opening of the beverage container.

In this configuration, the leverpivots on a hingemechanism and extends outward from the lid until it reaches a stop position, which prevents further rotation. The open leverprovides a mechanical advantage by acting as an extended handle, allowing the user to apply greater torque with less effort. This facilitates the easy removal of the lid from the beverage container. The lever'sergonomic design enhances user comfort and grip during operation, ensuring effective and efficient opening of the lid.

In this configuration, the user has utilized the handle to efficiently remove the lid from the container. This figure illustrates the engagement mechanismbetween the lever-enhanced lidand the beverage containerengagement mechanism. In this embodiment, the engagement mechanisms comprises threads, which are a common method for securing lids to containers. The threads on the lid correspond to matching threads on the beverage container, ensuring a secure fit and easy removal when the leveris deployed. This configuration provides a reliable and user-friendly method for sealing and unsealing the container.

Although the figures illustrated the leveras a pivoting lever, there are numerous ways and embodiments to implement a deployable lever. For example, the lever can fold over the top of the lid instead of the side or fold down towards the beverage container. Alternatively, the lever can slide out of the lid without folding.

The leverneed not be a distinct object but can be an integrated feature designed to be deployed as a lever tool with the lid. For instance, a straw designed with sufficient structural integrity to function as a lever may interact with the lid through specifically designed geometries, such as one or multiple holes, allowing the straw to pass through and act as a lever tool to impart greater torque.

Additionally, a stopper component can extend further out from the lid and be designed with sufficient strength to be utilized as a torque tool, facilitating easier opening of the lid. These embodiments provide a comprehensive understanding of the versatility and adaptability of the deployable leverconcept, ensuring the design can be tailored to various user preferences and container configurations.

Furthermore, although the primary embodiment describes a lid with an integrally designed deployable lever, there are embodiments that add a deployable lever, such as a foldable lever, to an existing lid. This approach allows users to retrofit their existing lids with enhanced functionality.

The variations in the lever'sdeployment method, whether folding, sliding, or integrating common objects like straws and stoppers, illustrate the broad applicability of the invention. This flexibility enhances the functionality of the lid, making it user-friendly and adaptable to different use scenarios and container designs without escaping the spirit of the invention and the scope of the claims.
