Abstract
A sippable lid for drinking from variable cups, glasses, bottles or any other circular-mouthed container adapted to hold fluids. The sippable lid generally comprises a resilient rubber skirt attachable to a hard plastic lid. The skirt is rubber while the lid is hard heat-resistant plastic. The lid is molded with cylindrical sidewalls topped by an offset parabolic drinking surface that slopes downward from fore to aft. A series of drinking holes are circularly-aligned along the rearward edge. The skirt includes a cylindrical upper sidewall fitted tongue-in-groove inside the lower edge of the lid sidewalls, a frusto-conical ribbed middle section, and a lower cylindrical sidewall having a diameter smaller than the upper cylindrical sidewall.
Description
- The present application derives priority from U.S. provisional application 62/832,031 filed 10 Apr. 2019 and from U.S. provisional application 62/913,255 filed 10 Oct. 2019.
- The present invention relates generally to drinking accessories and, in particular, a universal sippable lid for use with variably-sized containers.
- There are a variety of lids or container covers that are traditionally placed over beverage containers. For example, establishments serve hot coffee and provide a disposable lid with an opening to enable the coffee to be sipped.
- Most beverage containers have a rim with which the container cover makes a tongue and groove snap fit. However, the snap fit retention is not strong and in the event the beverage container is inadvertently tipped over, the lid or cover sometimes dislodges and hot coffee spills out onto to the floor, possibly burning the coffee drinker. Moreover, disposable lids are clogging landfills and causing severe environmental problems. What is needed is a reusable lid which is more securely snap fit onto a container for hot or cold beverages.
- It is known to provide a lid that simply screws over the top of a container. These provide a better seal, but the arrangement requires a thread to be provided on the upper surface of the container which increases the manufacturing cost, and also limits the lid to fitting a specific container size.
- Accordingly there is substantial need for a universal reusable lid for both hot and cold beverage containers that securely fits a variety of container sizes, eliminates drippage, seeping, splashing and leaking, and yet still provides a natural drinking sensation as opposed to drinking through a spout.
- According to embodiments of the invention, a sippable lid is provided for drinking from variable cups, glasses, bottles or any other circular-mouthed container adapted to hold fluids. The sippable lid generally comprises a resilient rubber skirt attachable to a hard plastic lid. The skirt is rubber while the lid is hard heat-resistant plastic. The lid is molded with cylindrical sidewalls topped by an offset parabolic drinking surface that slopes downward from fore to aft. A series of drinking holes are circularly-aligned along the rearward edge. The skirt includes a cylindrical upper sidewall fitted tongue-in-groove inside the lower edge of the lid sidewalls, a frusto-conical ribbed middle section, and a lower cylindrical sidewall having a diameter smaller than the upper cylindrical sidewall.
- The present invention is described in greater detail in the detailed description of the invention, and the appended drawings. Additional features and advantages of the invention will be set forth in the description that follows, will be apparent from the description, or may be learned by practicing the invention.
- Other objects, features, and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments and certain modifications thereof when taken together with the accompanying drawings in which.

- As illustrated in
FIG. 1 , the sippable lid according to the invention is a reusable lid or top, configured for drinking from variable cups, glasses, bottles or any other circular-mouthed container adapted to hold fluids. The present invention is capable of use with threaded and non-threaded containers. The sippable lid generally comprises two attachable components: aresilient rubber skirt 4 and a hardplastic lid 2. Theskirt 4 is preferably formed of a resilient, high friction material and preferably of silicone rubber, or other suitable rubber. Thelid 2 is preferably formed of a hard high heat-resistant polymer, such as polypropylene, polyesters, polyamides, ethylene-vinyl alcohol copolymer, polycarbonates and the like. - The
lid 2 is molded withcylindrical sidewalls 12 topped by a distinctlyconcave drinking surface 14 that is offset, sloping downward from rearward to forward edge. A series ofdrinking holes 16 are aligned along a circular path offset inwardly from the rearward edge. - As seen in
FIG. 2 theskirt 4 includes acylindrical sidewall 42 fitted tongue-in-groove inside the lower edge oflid sidewalls 12.Upper sidewall 42 leads to a frusto-conical ribbedsection 44,section 44 in turn leading to a lowercylindrical sidewall 46 having a diameter smaller than the firstcylindrical sidewall 42. As described below, the frusto-conical ribbedsection 44 is specially-designed to form a fluid-tight seal with any of a variety of variably-sized containers having circular mouths ranging in size from a first diameter ofcylindrical sidewall 42 to a second diameter ofsidewall 46. -
FIGS. 4-7 illustrate thelid 2 with exemplary dimensions.Cylindrical sidewalls 12 oflid 2 rise to an offsetparabolic drinking surface 14 that slopes downward from rearward to forward edge at an approximate 30 degree angle. The uppermost edge ofsurface 14 is defined by a series ofdrinking holes 16, three for example. Thedrinking holes 16 are aligned along a circular path that is offset inwardly from the rearward edge. In use the broadest part ofsidewall 12 oflid 2 sits atop the user's lower lip and theparabolic surface 14 falls sharply away such that no contact with the upper lip is made. Thelid 2 feels like an open glass. The series ofdrinking holes 16 allows liquid to drain outward and run downparabolic surface 14 falling uniformly into the mouth. - As seen in
FIG. 5 the inner lower surface of thesidewall 12 is defined by a 0.01″notch 124 for a tongue-in-groove fit withskirt 4. Similarly, as seen inFIG. 3 the rim of theupper sidewall 42 bears a 0.02″ w×0.06″ 1flange 126 for a tongue-in-groove fit with thenotch 124 oflid 2. -
FIGS. 8-11 illustrate theskirt 4 with exemplary dimensions. Thecylindrical sidewall 42 has a diameter d1,cylindrical sidewall 46 has a diameter d2 smaller than the firstcylindrical sidewall 42, and frusto-conical ribbedsection 44 segways the twosidewalls section 44 joins bothcylindrical sidewalls FIG. 10 to maximize the sealing ability ofskirt 4. - As seen in the inset of
FIG. 10 the rib shape and dimensions are optimized to ensure a fluid-tight seal with the widest possible range of variably-sized container mouths, including those with screw-threads. Toward this end, and given the above-described 19 degree offset angle of frusto-conical section 44 from vertical, eachrib 50 has a triangular profile with a 0.03″ downwardly-inclined face 52 and a 0.02″ inwardly-angled base 54. Preferablymultiple ribs 50 are equally spaced along the entire length of frusto-conical section 44, e.g., six (6) coaxial ribs spaced equally along the approximate 0.44″ length. The triangular profile ofribs 50 is preferably a right-triangle, offset from vertical such that the downwardly-inclined face 52 departs from the frusto-conical surface ofsection 44 by 30 degrees, returning to it at 60 degrees. Given the foregoing configuration theskirt 4 can be forcibly depressed down into a container mouth until the diameter of the container mouth equals that of theskirt 4. At this point the most equally-sized rib 50 encounters the container mouth such that the inclined base 54 ofribs 50 encounter the rim of the container at a sufficient angle to deflect therib 50 inward. As the apex of therib 50 drops below the rim of the container the outward bias of therubber skirt 4 and the angle of theface 52 continues to urge it downward, effectively affixing theskirt 4 in place. The sippable lid is effectively secured to the container and renders it leak and spill proof. Once the device is fastened to a container holding a fluid, a user can drink the fluid. The container can be anything with a circular mouth ranging from a drinking glass to a bottle. Regardless, the device can be attached such that it fits snugly around the lip of the mouth. Moreover, the relativelyflexible ribs 50 can form a seal around variable “twist-top” or “screw-on” grooves or notched openings, such as soda bottles; bottles with compression or “snap-top” seals, such as certain milk containers; and containers with permanently openings, such as aluminum cans or beer bottles. - The foregoing disclosure of embodiments of the present invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many variations and modifications of the embodiments described herein will be obvious to one of ordinary skill in the art in light of the above disclosure. The scope of the invention is to be defined only by the claims, and by their equivalents.
