## Abstract

A measuring cup includes a floor and sidewalls to define an internal volume. The floor is inclined to enable increasing volumes from a lowest point on the floor to the highest point on the floor. A first set of volumetric markings is positioned on the floor for measuring small volumes, and a second set of volumetric markings is positioned on the sidewall for measuring relatively larger volumes.

## Background
PRIORITY CLAIM 
This application claims the benefit of prior U.S. Provisional Application Ser. No. 61/933,610 filed Jan. 30, 2014; the contents of which are hereby incorporated by reference.


FIELD OF THE INVENTION 
This invention is generally related to measuring cups.
BACKGROUND OF THE INVENTION 
Standard measuring cups are configured to measure relatively large volumes of liquids, for example including increments of fractions or multiples of a cup. In order to measure smaller volumes, one must use different measuring devices such as measuring spoons having volumes that are typically in increments of fractions or multiples of teaspoons or tablespoons. This requires the use of many different measuring cups and spoons in order to facilitate the measurement of both large and small volumes.
SUMMARY OF THE INVENTION 
In accordance with preferred versions of the invention, a measuring cup includes volumetric markings positioned on vertical sidewalls to indicate measurements for relatively large volumes. In one version, the large volume measurements are in fractions or multiples of 1 cup.
The preferred measuring cup also includes a floor having one end that is lower than the opposite end, and which in one example of the invention is inclined continuously from a first lowest end to a second highest end. In one example of the invention, the floor of the measuring cup is lowest beneath the spout and highest at a diametrically opposite location adjacent a handle. In some versions, no handle is included.
A second set of volumetric measurements is provided on the floor itself with the second set of volumetric measurements being in fractions or multiples of teaspoons or tablespoons. The volumetric measurements located on the floor are in increments that are preferably much smaller than those on the sidewall. In one preferred version, the largest measurement on the floor of the measuring cup is smaller than, or equal to, the smallest initial measurement located on the sidewall of the measuring cup.
Accordingly, a single measuring cup in accordance with the preferred embodiment is able to measure increments of both relatively large volumes and relatively small volumes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
A preferred measuring cup 10 is shown in the accompanying figures, including a first version illustrated in FIGS. 1-5 and a second version illustrated in FIGS. 6-8. In each case the measuring cup includes common features of two different sets of volumetric markings, one of which is placed on an inclined surface on the floor of the measuring cup. The two differ in the shape of the floor and sidewalls, as well as in the shape of the base for supporting the inclined floor of the cup.
With reference to the cup 10 of FIG. 1, the illustrated version includes a handle 14 and a spout 12. The handle and spout are optional features which may be omitted from other versions of the invention. The measuring cup includes a floor 30 surrounded by upwardly extending sidewalls 20 in which the floor and sidewalls are joined together to form an interior space. In the illustrated version, the floor is supported by a foundation or base 40 to provide an upright support for the measuring cup when resting on a horizontal surface.
In the illustrated version, the handle 14 is positioned at a first side of the cup while the spout 12 is positioned at a diametrically opposite location on the cup. In other versions, the measuring cup may not include a handle or spout, or alternatively, the spout may be located in a different position with respect to the handle.
In the illustrated version, and as best seen in the sectional view of FIG. 4, the floor is inclined from a lowest position 34 directly beneath the spout and is angled upwardly continuously to a highest position 35 directly opposite the spout and adjacent the handle. This configuration allows a small volume of liquid 50 (shown in FIG. 1) to collect at the lowest portion of the floor adjacent the sidewall extending upwardly from the lowest portion of the floor.
As best seen in FIG. 4, a first set of volumetric markings 22 is positioned on a sidewall of the container 20, with the first set of volumetric markings being configured to indicate corresponding volumes within the container between the floor and a corresponding position on the sidewall of the measuring cup aligned with markings positioned on the sidewall. In one version, the first set of volumetric markings are configured to indicate relatively large volumes such as increments or fractions of 1 cup. Thus, for example, the first set of volumetric markings may range between 1⁄8 of 1 cup and 1 cup in one version of the invention, or between one quarter of 1 cup and 2 cups in another version of the invention.
Most preferably, a smallest unit of measure defines the volume within the container between the floor 30 and the smallest volumetric marking 25, as shown in FIG. 4. In one version of the invention, the smallest marking defines a volume which is larger than the largest volume indicated by the second set of markings, as described below.
As best seen in FIG. 5, a second set of volumetric markings 32 is provided on the floor 30 of the container. The second set of volumetric markings is configured to indicate volumes within the measuring cup in a space between the floor of the measuring cup and a portion of the surrounding sidewalls of the measuring cup. Thus, all or nearly all of the markings within the second set of volumetric markings will correspond to a volume of liquid in which the liquid does not entirely cover the floor of the container. The second set of volumetric markings therefore define volumes in which the lowest point of the volume is positioned at the lowest point 34 of the floor, and the highest point of the volume 33 is positioned at an intermediate location along the inclined floor between the lowest point 34 of the floor and the highest point 35 of the floor. In addition, in a preferred version the volume indicated by the largest volumetric marking 33 positioned on the floor 30 is smaller than the volume indicated by the smallest volumetric marking 25 positioned on the sidewall.
In the version as illustrated in FIGS. 1-5, the floor 30 of the measuring cup 10 is generally triangular in shape, with an apex of the triangle being located at the lowest position 34 on the floor. This narrowing of the floor at the bottom of the inclined floor further enables the floor to be used to define small volumes.
The principles of the present invention are best suited for measuring cups configured as short wide cylinders or other similarly shaped containers. In an alternate version as illustrated in FIGS. 6-8, the measuring cup is generally cylindrical, rather than having the generally triangular base as shown in the version of FIGS. 1-5. Thus, the alternate illustrated version of the measuring cup has an upper rim having a diameter D1, as shown in FIG. 7. Though characterized as a “diameter,” it should be understood in this context to apply to a widest distance across opposing sides of the measuring cup, even if the rim does not define a circular shape. The measuring cup also includes a lower floor diameter D2, as shown in FIG. 8, which as indicated extends across a widest horizontal distance between the lowest part of the floor and the opposing highest point on the inclined floor. The measuring cup further has a height H between the lowest part of the floor and the top of the rim.
Most preferably, the height H of the measuring cup is less than twice the lower diameter D2, and more preferably the height H is less than 1.5 times the lower diameter D2. In the preferred version the height H is between 1 and 1.2 times the lower diameter D2. In addition, in the preferred version the total internal volume is at least one cup and may be two cups or more. The relatively large lower diameter D2 with respect to the height H, together with the volume of one cup or more, enables the second set of volumetric markings to encompass a relatively wide range of measurements between a fraction of a teaspoon (for example, 1⁄4 or 1⁄2 of a teaspoon) and a tablespoon or more (for example, 2 or 3 tablespoons).
It should further be understood that while the foregoing description is made with reference to volumes expressed in teaspoons, tablespoons, and cups, measurements in other units should be considered equivalent, such as volumes in ounces, liters, or milliliters.
In one version of the invention, the volumetric indicators in the first set of indicators do not overlap the second set of indicators. In other words, the largest volume indicated on the second set of indicators is less than or equal to the smallest volume indicated on the first set of indicators. In other versions, the first and second set of indicators may overlap somewhat, but preferably the degree of overlap is such that the smallest measurement 25 indicated in the first set of indicators 22 is larger than the middle volume 34 (see FIG. 5) in the range of volumes expressed in the second set of indicators 32. This relationship between the diameter, height, and range of volumes combines to form a container having two sets of volumetric markings for groupings of relatively large and relatively small volumes.
While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
