Description

FIELD OF THE INVENTION

The present invention relates generally to a disposable leak-resistant device. More specifically, this application relates to a leak resistant disposable drinking lid for use by young children.

BACKGROUND OF THE INVENTION

Leak-resistant lids are commonly known in the present art and are frequently associated with cups commonly referred to as “sippy cups”. These cups are most commonly used for young children who are prone to spill, or for the consumption of very hot fluid in which the intake of such a fluid should be regulated to avoid scalding.

Sippy cup spouts often have small holes or slots that allow fluid to pass at a minimal rate when held upside down. Some spouts have larger holes than others to increase the ease of cleaning or for the passage of small drink particles, such us pulp or bits of fruit. Instead of constantly open holes or slots, some sippy cups utilize valves that completely restrict the flow of fluid until suction is applied. This design is preferred by one who wishes to reduce the rate of leakage when the cup is not in use, while sacrificing flow rate while the cup is in use.

Disposable embodiments of the above inventions described above focus on leak-resistant cups used primarily in the home. Generally, an adult pours a child's beverage from a container into a sippy cup, thereby minimizing the risk of spilling. This method is inefficient, however, especially for the parent on the go. The hassle becomes more apparent when one considers the method taking place in a car. Beverages served in containers without straws, such as MILK CHUG, are commonly served at fast food restaurants, such as MCDONALDS™, and while these beverages offer a healthy alternative to soda, children are prone to spill the contents of the container the beverage is served in due to a lack of a leak-resistant lid. There remains a need for a disposable leak-resistant lid adapted to fit this type of container. More specifically, it would be desirable for a place of sales to offer various-sized disposable leak-resistant lids that are able to threadedly secure to a reciprocating, externally threaded fluid-holding container.

SUMMARY OF THE INVENTION

The present invention addresses the above discussed need by providing a disposable leak-resistant lid that attaches threadedly to a reciprocating externally threaded fluid-holding container, wherein the container is not originally intended or packaged with such a lid. Rather, a consumer has the choice to modify the container by attaching the disposable leak-resistant lid disclosed herein.

It is therefore an object of the invention to provide a disposable leak-resistant lid comprising: a crown, wherein the crown further comprises a top surface and a bottom surface, wherein the top surface provides a spout, having a spout opening disposed to communicate the top surface with the bottom surface, and wherein only a minimal amount of liquid may pass through said spout opening unless sufficient suction is applied; and a lid skirt, wherein the lid skirt is associated circumferentially with said crown, and downwardly extends from said crown, and disposed to helically thread onto the externally threaded opening of a container for sealing such a container in a fluid-tight manner.

It is another object of the invention to provide a disposable leak-resistant device comprising: a disposable container, wherein the container is defined by an interior cavity and top opening, wherein said top opening is associated with said interior cavity, wherein a stored liquid may freely pass from the container's interior cavity through said opening, and wherein said opening is externally, helically threaded, and able to receive a reciprocating helically threaded closure so that the newly formed seal is fluid-tight; and a disposable lid, comprising a crown and lid skirt, wherein the crown further comprises a top surface and a bottom surface, wherein the top surface provides a spout, having a spout opening disposed to communicate the top surface with the bottom surface, and wherein only a minimal amount of liquid may pass through said spout opening unless sufficient suction is applied, and wherein said lid skirt is associated circumferentially with said crown, and downwardly extends from said crown, and disposed to helically thread onto the reciprocating, externally threaded opening of said container for sealing said container in a fluid-tight manner.

It is yet another object of the invention to provide a method of selling a disposable leak-resistant lid, comprising the steps of selling a beverage, wherein said beverage is packaged in a container, utilizing a traditional, helically-threaded closure, wherein said traditional closure restricts any fluid stored within said container to be able to pass through the opening of said container, unless said closure is unthreaded and removed; and offering the consumer the option of utilizing the disposable leak-resistant lid to attach to said container as an alternative to said closure.

These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION

In general terms, the invention concerns a device and method for adapting beverage containers, closed by means of traditional no-leak, lids, into leak-resistant containers for use by children. More particularly, the invention seeks to offer the ability to utilize a disposable leak-resistant lid as an alternative to the lid that a container is originally manufactured with.

While the present invention and method is described herein with reference to one illustrative embodiment, it should be clear that the present invention should not be limited to the one embodiment.

Referring now to FIG. 1, a disposable leak-resistant lid 100 is shown. The disposable leak-resistant lid 100 may consist of a crown 110, wherein the crown is further comprised of a top surface 112 and a bottom surface 114. The top surface 112 provides a spout 116 that is able to communicate the top surface 112 with the bottom surface 114 by means of a spout opening 118.

The spout opening 118 is designed to make the disposable leak-resistant lid 100, restrictive to a large amount of fluid that may be evacuated from the spout opening at any single time. Spout opening 118 achieves this restrictive quality by allowing a substantial amount of liquid to pass only once sufficient suction is applied to the spout 116. The spout opening 118 may consist of a plurality of holes (as shown), a single hole, slit(s), or slot(s). The size of the above mentioned openings would determine the amount of liquid and ease of which an amount of liquid is able to pass through said opening.

The material the disposable leak-resistant lid 100, and more particularly the spout 116, is constructed of, may influence the restrictive quality of the lid. The disposable leak resistant-resistant lid 100 may be constructed of a self-healing membrane, in which the spout opening's 118 perimeter would slightly increase in size once suction is applied and slightly decrease in size once suction is stopped.

Turning now to FIG. 2 and FIG. 3, the underside of the disposable leak-resistant lid 100 is shown. A lid skirt 120 is associated circumferentially with the crown 110. The exterior of the lid skirt 120 may be gripped by a user, and consist of a texture to make the leak-resistant lid more easily gripped and turned. The interior of the lid skirt 120 contains helical thread-tracks 122 intended to threadedly attach to the receiving thread-tracks 134, exposed externally on the opening 132 of the container 130 (FIG. 3).

It should be appreciated that the disposable leak-resistant lid 100 is specifically manufactured to the specific dimensions necessary to attach to the container 130. However, the invention is intended to be manufactured in various sizes, with various thread track types, in order to attach to various-sized openings of various containers.

FIG. 4 shows an alternative embodiment 200 of the leak resistant lid. Here, a generally cone shaped lid is shown with a spout 216 located on the peak of the cone 252, thereby creating a plateau on the top surface 212 of the leak resistant lid 200.

Turning now to FIG. 5, another alternative spout 316 of the disposable leak-resistant lid 300 is shown. Here, the spout is shown to include a valve assembly 350 that completely restricts fluid communication from the disposable leak-resistant lid's e00 bottom surface e14 to top surface e12 until suction is applied. It should be appreciated that numerous valve assemblies are known in the field, and that any of which may work in conjunction with the invention described herein.

With the foregoing background in mind, and referring now to the flowchart of FIG. 6, which summarizes elements of the method 500, the novel method 500 may comprise the following steps.

A step 502 is that of a place of sales providing a beverage to a consumer, wherein the beverage is packaged in a container utilizing a traditional helically threaded closure, wherein said traditional closure restricts any fluid stored within said container to be able to pass through the opening of said container, unless said closure is unthreaded and removed.

Lastly, a step 504 is that of the place of sales offering the consumer the option of utilizing the disposable leak-resistant lid 100 to attach to said container as an alternative to said traditional closure.

While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is to be understood that the present invention is not to be limited to the disclosed arrangements, but is intended to cover various arrangements which are included within the spirit and scope of the broadest possible interpretation of the appended claims so as to encompass all modifications and equivalent arrangements which are possible.
