LID WITH LOWER SANITARY EXTENSIONS
To make it easier and more hygienic to handle a lid when it is removed from a beverage container and needs to be set aside temporarily on a supporting surface, bottom lid extensions are provided that lift the lid to eliminate or significantly reduce the contact between the supporting surface and the wetted underside surfaces of the lid that may come in contact with the beverage.
The present application claims priority to U.S. Provisional Patent Application No. 63/090,214, filed Oct. 10, 2020, the entire contents of which are incorporated herein by reference.
TECHNICAL FIELDThe present disclosure relates generally to drink containers and, more specifically but not exclusively, the present disclosure relates to a lid assembly for a drink container (e.g., a container for a beverage, a liquid, flowable food, cups, mugs, and the like).
BACKGROUND INFORMATIONMany times, when people fill their travel cups, they need to set the lid aside on a service area like a countertop surface to free their hands for other activities like reaching for their wallet or adding cream or sugar. When the lid is placed face up on the service area, portions of the underside of the lid that may normally come in contact with the beverage may touch the service area, thereby becoming contaminated. Also, a used lid can smudge a countertop area with beverage residue.
There are other situations that require handling the lid separately, such as when cleaning the lid and the cup after usage. Here, the lid also needs to be set aside when only the cup is cleaned and, again, the lid might become contaminated when contacting the cleaning area or the lid can smudge a clean countertop.
SUMMARYThe present disclosure relates to a lid assembly for a drink container (e.g., a container for beverage/liquid/flowable food, cup, mug, or the like). In accordance with embodiments of the present invention, the lid is generally configured to engage a top periphery of a drink container and substantially cover an open top surface of the container to prevent splashes and possibly spills. The lid includes a sip hole and has a wetted underside that can come in contact with the content of the drink container when the content is consumed, or the container is transported. The lid may also include a nose recess that extends down in the drink container.
Provisions in the form of raiser extensions are incorporated in the lid that lift the underside of the lid off a flat, mostly horizontal surface on which the lid is placed face up. As used herein, the “face up” direction of the lid refers to the orientation of the lid when placed on top of a container, such that the side of the lid that faces the contents of the container is on the bottom. An underside of the raiser extension is defined as the area that comes in contact with the service area when the lid is placed on it face up.
Depending on the construction of the lid, the extensions can be placed on the part of the lid that is outside of the drinking container. These extensions do not come in contact with the beverage and therefore no contamination occurs. Raiser extensions are preferred to having the entire circumference extending down because they save materials, make the lid easier to clean, and make the lid less bulky and easier to handle. The raiser extensions are to be placed in such a way as to envelope the center of gravity of the lid so that the lid is in equilibrium, meaning it does not lean on a side when let free.
If placing the raiser extensions outside of the drinking container is not desirable or possible, the extensions can be placed on a part of the lid that resides inside the beverage container. If the raiser extensions are placed inside the drinking container, the total wetted area is formed by the area of the underside of the circular body and the underside of the raised extensions. The underside of the raised extensions can come in contact with the service area when the lid is placed on it face up. Minimizing the contact area can be achieved by using a pointed shape for the raiser extensions. Since the extension underside area that touches the service area is significantly reduced compared to the area the underside of the lid would have touched the service area if the raiser extensions were not there, the contamination and smudging are significantly reduced. The contact area is usually reduced to three point type areas to keep the lid from tipping.
It is possible to have a combination of outside extensions and inside extensions. In this case the wetted area that can comes in contact with a service area can be reduced to just one point which further reduces the contact area of the inside extensions.
The foregoing features of the present disclosure will be apparent from the following detailed description of the present disclosure, taken in connection with the accompanying drawings, in which:
The present disclosure relates to a lid for a drink container. The lid includes built-in raiser extensions that eliminate or minimize the wetted areas underside the lid that comes in contact with a flat surface when the lid is set face up on a service area.

In some embodiments, the lid underside wetted area may come in contact with the flat surface when the lid is tipped. In such cases it is important that the lid is stable and does not tip easily. The stability of a lid is defined by its equilibrium which, for the practical purposes of this disclosure, can be stable, marginally stable, or unstable. An unstable equilibrium is when the center of gravity CG is outside the base of support of the lid. A marginally stable equilibrium is when the center of gravity is inside the base of support but very close to or on the periphery of the base of support. A stable equilibrium is when the center of gravity is inside the base of support and at a distance from the periphery of the base of support.
A stable equilibrium means that the user can set the lid down easily without trying too hard to find an equilibrium position. It also means that the lid will stay in that position even if a small perturbance occurs such as somebody inadvertently touching the lid. For example, a lid having only two curved raiser extensions may result in an unstable or marginally stable equilibrium, because the base of support provided by the curved raiser extension would narrow to a point or very small region where the bottom of the curved edge of the raiser extension contacts the surface on which the lid is placed. As a result, the lid would have a tendency to wobble around the curved edge of the raiser extension. Embodiments described herein which incorporate raiser extensions having flat bottom portions, or incorporate three or more raiser extensions, can provide a larger base of support, thereby improving stability.
For the purposes of this disclosure, the type of equilibrium is defined relative to a representative dimension for the size of the lid. In the case of the lids in
It is understood that the lid does not necessarily have to have a nose recess to benefit from the raiser extensions. For example, some lids have a spill-proof stopper mechanism that can extend deeper into the cup similar to the nose recess. These lids can also be fitted with outside or inside raiser extensions to keep the bottom wetted area of the lid from contacting a possibly contaminated service area.
In accordance with embodiments of the present invention, a lid may include at least two raiser extensions, each having a flat bottom portion that contacts the flat surface on which the lid is placed. In some embodiments, the lid includes exactly two such raiser extensions with flat bottom portions. In accordance with other embodiments, a lid may include exactly three extensions, thereby providing stable support for the lid, regardless of the shape of the extensions. In other embodiments, more than three extensions may be provided.
Different combination can be considered, for example two support points or one continuous edge for the outside raiser extension and one pointed raiser extension on the inside. Or, one can have one support point on the outside and two support points on the inside.
The description of embodiments of the disclosure is not intended to be exhaustive or to limit the disclosure to the precise form disclosed. While specific embodiments and examples for the disclosure are described herein for illustrative purposes, various equivalent modifications are possible within the scope of the disclosure, as those skilled in the relevant art will recognize. Such modifications may include, but are not limited to, changes in the dimensions and shapes of the disclosed embodiments.
