Vessel with measuring capability
Abstract
A measuring vessel has cavity-defining wall structures and at
least one ramp which rises from about the bottom of the wall
structure toward the top of the wall structure. The at least one
ramp has an upwardly directed surface with a lateral inner edge
integral with portions of the wall structure below the ramp and a
lateral outer edge integral with portions of the wall structure
below the ramp. Indicia on the upwardly directed surface of the at
least one ramp allows a user to look downwardly into the measuring
vessel to visually detect the volume level of the contents in the
vessel, thereby eliminating the need to look horizontally at the
vessel at eye level. Preferably the vessel has two ramps, with at
least one bearing indicia of standard English units, and another
bearing indicia of metric units. In one embodiment a handle,
covered with a cushioning grip sheath, is cantilevered from the top
of the wall structure and has a distal end at the level of the
bottom of the wall structure for cooperation therewith to support
the vessel on an underlying support surface.

Description
BACKGROUND
This invention relates to vessels for containing measurable
contents. More specifically, this invention relates to a vessel
having graduated indicia.
Vessels such as cups, bowls, spoons and the like which have a
measuring capability are known. Such devices can be made from a
variety of materials, including plastic, metal and glass. One of
the most common measuring vessels found on the market today is a
transparent measuring cup made of Pyrex.RTM. which is resistant to
sudden changes in temperature to which it may be subjected during
use.
The utility derived from a measuring vessel is related to the ease
with which volumetric indicia on the measuring vessel's wall may be
read by a user. Of course, any suitable units of measurement may be
used to indicate the level to which contents have risen within a
measuring vessel.
Traditional measuring vessels have indicia marked upon the
measuring vessel wall in a manner which sometimes makes the indicia
difficult to read, depending upon how precise a measurement is
needed, the materials from which the measuring vessel is
manufactured and the physical condition of the user, for example.
In the case of a measuring cup which is made from transparent or
translucent material, e.g., Pyrex.RTM., the most precise way to
measure the contents contained therein is to place the measuring
cup upon a level surface, pour the contents to be measured into the
measuring cup and then stoop down to the vertical level of the
measuring cup to attempt to visually detect the bottom of a liquid
meniscus or a level surface of solid contents. An alternative
method of reading the level to which contents in a transparent or
translucent measuring cup have risen is to lift the measuring cup
to eye level and attempt to hold the measuring cup steady while
visually detecting the volume. In either use, the observer is
looking in a generally horizontal direction to detect the
volume.
Prior art measuring cups that are opaque are more difficult to read
than transparent or translucent measuring cups. In order to read
the volume of contents held within an opaque measuring cup, a user
must peer over the upper margin of the measuring cup to view, as
closely as possible, the level to which contents have risen, either
by stooping to the measuring cup's level or by lifting the
measuring cup to eye level.
While the above-described methods for determining the volume of
contents in a measuring cup may seem simple enough for most users,
these methods can prove to be difficult for others. Users with bad
knees, a bad back, or arthritis, for example, may not only have
substantial difficulty in stooping over to accurately read the
volume of contents in a measuring cup placed on a level surface,
but may also have just as much difficulty in lifting a measuring
cup to eye level and holding the cup steady to read the volume of
contents held therein. When precise measurement of the volume of
contents within a measuring cup is critical to a task, the simple
actions of bending over or lifting a measuring cup to eye level,
which seem easy to some users, may become difficult and
uncomfortable for others.
Measuring the volume of cooking ingredients using prior art
measuring cup can also be frustrating. As mentioned above, it an be
difficult for a user to stoop over to read the level of contents
when placed on a level surface or when lifted to eye level. An
unsteady hand not only makes the volume of contents difficult to
determine when a measuring cup is lifted to eye level, but a user
may spill contents or even drop the measuring cup when attempting
to do so.
Measuring vessels are not limited in their utility to the kitchen,
of course. They may also be used for measuring proper ratios of
solutions, e.g., antifreeze, the precise measurement of which is
critical to its application and simplicity of determining a precise
volume is necessary. Other common household solutions can be
dangerous, e.g., toxic or caustic, and when a measuring vessel is
filled with these solution the possibility of spilling them within
the proximity of a child or a pet greatly increases when a
measuring vessel must be raised to eye level to determine the
volume of its contents.
It is an object of the present invention to simplify the way in
which a person can accurately determine the volume of material held
in a vessel.
It is another object of the invention to improve a measuring vessel
to make it mote conducive to a simple and accurate volume
determination.
SUMMARY
The present invention achieves the above-stated objectives by
including with a vessel at least one sloped ramp having an upwardly
directed surface having indicia which are readily observable by an
observer looking downwardly toward the open end of the vessel.
The structure simplifies volume determination because there is no
need for the observer to move relative to the vessel in order to
look in a horizontal direction at the vessel indicia. Thus, the
possibility of spilling is reduced. Also, since the ramp preferably
rises continuously and gradually from the bottom of the vessel, a
user who is filling the vessel from above can actually see the
volume indicia on the upwardly directed surface of the ramp while
the vessel is being filled, looking along the same line of sight
generally used during filling. These advantages result from the
ability to visually determine the volume of the contents of the
vessel by simply looking into the open upper end, and the gradual
slope of the ramp.
According to a first preferred embodiment of the invention, a cup
has wall structure including a bottom wall and an encircling
vertical side wall, so that the cup is cylindrical in shape with an
open upper end. Inside the cup, at least one ramp slopes
continuously upward from the bottom wall toward the open upper end.
The ramp includes an upwardly directed surface bearing printed
volume indicia viewable through the open upper end to visually
determine the volume of cup contents. Preferably the cup has two
ramps formed integrally along the side wall, with one bearing
standard English units of measurement and the other bearing metric
units. The two ramps have oppositely located bottom ends and
oppositely located top ends. The cup also has a handle and a spout,
with the handle located adjacent one ramp and the spout located
adjacent another.
In a second embodiment, the side wall is sloped somewhat, rather
than vertical. The cup includes two integral, oppositely located
ramps with adjacently located bottom ends and adjacently located
top ends. The top ends feed toward the spout, and again, one ramp
bears indicia in standard English units and the other bears metric
indicia.
In another embodiment, the handle is cantilevered from the side
wall and has a vertical grip portion terminating at a distal end in
the plane of the bottom wall to provide additional self-support,
and covered with an elastomeric grip sheath.
With any embodiment, the cup can be formed of any suitable material
and via any suitable process, although transparent and moldable
material is preferred and manufactured using a molding process is
also preferred.
Certain ones of these and other features may be attained by
providing a vessel comprising: a wall structure defining a cavity
with an open upper end for receiving contents having a measurable
volume, a continuous ramp extending upwardly from adjacent to a
lower end of the wall structure, and indicia positioned on the ramp
so as to be observable by a user looking downwardly toward the open
upper end and providing a readily observable indication of the
volume of the contents of the vessel.
These and other features will be more readily understood in view of
the following detailed description and the drawings.

DETAILED DESCRIPTION
FIGS. 1-3 show a first preferred embodiment of the present
inventive vessel in the form of a measuring cup 10. Generally, the
measuring cup 10 is integrally formed of a suitable material and
has a handle 12 and a spout 14 integrally attached to a
substantially vertical side wall 16. The measuring cup 10 has a
base or bottom wall 18 integrally attached around its perimeter to
the bottom edge of the side wall 16. The side wall 16 cooperates
with the bottom wall 18 to form wall structure which defines a
cavity which has an open upper end.
The wall 16 has an inside surface 20 and an outside surface 22 from
which ramps 24a, 24b are formed in relief. The measuring cup is of
unitary, one-piece construction, molded from any suitable food
grade plastic known in the art. However, it will be understood that
the measuring cup 10 may be manufactured by any suitable process.
It will also be understood that the measuring cup 10 may be made of
any other suitable material known in the art, e.g., Pyrex.RTM. or
metal.
The ramps 24a, 24b are located on opposite sides of the cup 10 but
are identical in construction. Therefore, only one such ramp is
described. Each ramp has a ramp base, or bottom end 25, and a ramp
top or upper end 26. The ramp base 25 is located proximate the
bottom edge of the side wall 16, and the ramp top 26 is located
proximate the top edge of the side wail 16. The ramps 24a, 24b have
respective upper ramp surfaces 30a, 30b, which are generally
upwardly directed and have a substantially constant slope between
the ramp base 25 and the ramp top 26. In the first preferred
embodiment, the ramps 24a, 24b are oppositely disposed on the
inside surface 20 of the wall 16. Also, in the first preferred
embodiment, the ramps 24a, 24b traverse substantially the same
distance from the bottom margin of the wall 16 to the top margin of
the wall 16 along the inside surface 20. It will be understood by
those skilled in the art that the ramps 24a, 24b may have a greater
or lesser slope, which in turn would result in shorter or longer
distances, respectively, traveled from the bottom margin to the top
margin of the wall 16.
The ramps 24a, 24b have a slope great enough so that the ramps 24a,
24b do not extend more than half the circumference of the wall 16,
as seen in FIG. 2. Also, the ramps 24a, 24b do not overlap each
other. That is, the ramp 24a does not rise over the ramp 246 on the
inside surface 20 of the wall 16. In the first preferred embodiment
of the measuring cup 10, the side wall 16 is substantially normal
to the base 18, so that the cup 10 is generally cylindrical in
shape. In the illustrated embodiment the side wall 16 is slightly
oval in transverse cross section but it could be circular or have
other shapes. It will be understood by those skilled in the art
that the wall 16 may angle away from the perimeter of the base 18
so that the measuring cup 10 may receive a second measuring cup
(not shown) therein, i.e., allow plural measuring cups 10 to stack
inside each other.
Each of the ramps 24a, 24b is provided with volume indicia 27a,
27a, on the upwardly directed surface 30a, 30b, so a user may
easily look down toward the measuring cup 10 from above and view
the volume level of the contents 28 within the cup 10. In the first
preferred embodiment, the ramp 24a is provided with metric indicia
27a on ramp surface 30a, and ramp 24b is provided with standard
English indicia 27a on ramp surface 30b. It will be understood by
those skilled in the art that the indicia 27a, 27a may be spaced
differently relative to each unit of measurement on respective
ramps 24, 24b, depending on the desired slope of the ramps 24a,
24b.
The side wall 16 has portions below the ramps 24a, 24b integral
with the lateral inner edges of the ramp surfaces 30a, 30b, and
portions above the ramps integral with the lateral outer edges of
the ramp surfaces 30a, 30b.
FIGS. 4-6 show a second preferred embodiment of an inventive
measuring cup 100. The measuring cup 100 has wall structure
including a side wall 116 integral with a bottom wall or base 118
for cooperation therewith to define a cavity with an open upper end
132 having a width A larger than the width B of the bottom wall or
base 118. Thus, the side wall 116 slopes outwardly away from the
base 118 as the side wall 116 rises from its bottom edge to its top
edge so that at least a second measuring cup 100' (FIG. 6) can be
stacked within the measuring cup 100. The cup 100 has a handle 112
projecting from the side wall 116 adjacent to its upper end, and a
spout 114 projecting from the upper end of the side wall 116
opposite the handle 112, the spout 114 having a lower entry end and
an upper exit end at the open upper end 132. The measuring cup 100
has a pair of oppositely located, but identically sloped ramps 124
which are substantially continuous around the side wall inside
surface 120 from the ramp bottom 125 toward the ramp top 126. That
is, both ramps 124 rise symmetrically along the inside surface 120
of the side wall 116 from about the bottom edge of the side wall
inside surface 120 generally opposite the spout 114 to near the top
edge of the side wall 116 adjacent to the base of the spout
114.
Because the open upper end 132 has a greater width A than the width
B of the base 118, upper surfaces 130 of the ramps 124 bear indicia
127a, 127a which are not spaced in equal intervals. That is, a
given rise in level 128 of the contents near the bottom edge of the
side wall 116 requires a smaller volume than an equal rise in the
level of the contents near the upper edge of the side wall 116. As
a result, the indicia 127a, 127a are spaced upon the ramps 124
closer together near the top edge of the side wall 116 than at the
bottom edge for an equivalent volume of contents 128. It will be
understood by those skilled in the art that the progressive change
in the diameter of the measuring cup 100 from the base 118 to the
upper edge of the side wall 116 may also be accommodated by
decreasing the slope of the ramps 124 from the lower edge of the
side wall 116 to the upper edge of the side wall 116 while
maintaining the spacing between indicia 127a, 127a along the ramps
124.
Also in this embodiment, the ramp tops 126 are continuous with an
inner surface of the spout 114 to allow a user to more easily pour
contents from the measuring cup 100 without spilling.
The side wall 116 has a lower portion 116a below the ramps 124
which is offset inwardly by the width of the ramp upper surfaces
130 from an upper portion 116b of the side wall 116. This offset
allows other measuring cups 100' to nest within the measuring cup
100 and each other when stacked. More specifically, the lower
portion 116a of the side wall 116, which is below the ramps 124, is
integral with the lateral inner edges of the ramps, while the upper
portion 116b, which is above the ramps, is integral with the
lateral outer edges of the ramps.
FIGS. 7 and 8 show another embodiment of an inventive measuring cup
200. The measuring cup 200 has wall structure including a side wall
216 integral with a bottom wall or base 218 for cooperation
therewith to define a cavity with an open upper end 232 having a
width larger than the width of the bottom wall or base 218. Thus,
the side wall 216 slopes outwardly away from the base 218 as the
side wall 216 rises from its bottom edge to its top edge. The cup
200 has a handle 212 projecting from the side wall 216 adjacent to
its upper end, and a spout 214 projecting from the upper end of the
side wall 216 opposite the handle 212, the spout 214 having a lower
entry end and an upper exit end at the open upper end 232. The
measuring cup 200 has a pair of oppositely located, but identically
sloped ramps 224 which are substantially continuous around the side
wall inside surface 220 from the ramp bottom 225 toward the ramp
top 226. That is, both ramps 224 rise symmetrically along the
inside surface 220 of the side wall 216 from about the bottom edge
of the side wall inside surface 220 generally opposite the spout
214 to near the top edge of the side wall 216 adjacent to the base
of the spout 214.
Because the open upper end 232 has a greater width than the width
of the base 218, upper surfaces 230 of the ramps 224 bear indicia
227a, 227a which are not spaced in equal intervals for the same
reasons indicated above for the cup 100. It will be understood by
those skilled in the art that the progressive change in the
diameter of the measuring cup 200 from the base 218 to the upper
edge of the side wall 226 may also be accommodated by decreasing
the slope of the ramps 224 from the lower edge of the side wall 216
to the upper edge of the side wall 216 while maintaining the
spacing between indicia 227a, 227a along the ramps 224.
The side wall 216 has a lower portion 216a below the ramps 224
which is offset inwardly by the width of the ramp upper surfaces
230 from an upper portion 216b of the side wall 216. More
specifically, the lower portion 216a of the side wall 216, which is
below the ramps 224, is integral with the lateral inner edges 224a
of the ramps, while the upper portion 216b, which is above the
ramps, is integral with the lateral outer edges 224b of the
ramps.
The periphery of the bottom wall 218 lies in a base plane P to
provide a stable support on an underlying support surface. The
handle 212 is generally L-shaped, having a short arm 213 projecting
laterally outwardly from the side wall 216 and integral at the
outer end thereof with an elongated depending grip portion 215
which extends substantially perpendicular to the base plane P and
terminates at a generally flat distal end 217 which lies
substantially in the base plane P. Thus, when the measuring cup 200
is resting on its base or bottom wall 218, the end 217 provides an
additional support point. Furthermore, the depending portion 215 of
the handle 212 is covered with a grip sheath 219, preferably formed
of a suitable flexible and cushioning elastomeric material, such as
that sold under the trade name SANTOPRENE. This affords a
comfortable, non-slip, frictional grip surface to facilitate
grasping of the handle 212.
While in the disclosed embodiments the ramps have fixed or constant
slopes, it will be appreciated that the slopes could vary. Also,
while each of the disclosed embodiments has two ramps, a single
ramp could suffice. Preferably, the entire measuring cup is formed
of a transparent material, but, if desired, the ramps could be
translucent to enhance contrast with the vessel side walls.
While the illustrated embodiments are cups, it will be appreciated
that the principles of the invention are applicable to other
vessels, such as bowls, ladles, spoons and the like and, indeed, to
any vessel-defining structure, whether or not self-supporting and
whether or not provided with a handle or a spout, and of any size
or shape.
The matter set forth in the foregoing description and accompanying
drawings is offered by way of illustration only and not as a
limitation. While particular embodiments have been shown and
described, it will be apparent to those skilled in the art that
changes and modifications may be made without departing from the
broader aspects of applicants' contribution. The actual scope of
the protection sought is intended to be defined in the following
claims when viewed in their proper perspective based on the prior
art.
