Description
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0001] n/a
BACKGROUND OF THE INVENTION
[0002] Various embodiments relate generally to food storage systems
and devices and, more specifically, relate to vacuum-insulated food
storage containers with complementary lids.
[0003] This section is intended to provide a background or context.
The description may include concepts that may be pursued, but have
not necessarily been previously conceived or pursued. Unless
indicated otherwise, what is described in this section is not
deemed prior art to the description and claims and is not admitted
to be prior art by inclusion in this section.
[0004] Maintaining the proper temperature for foods after
preparation but before consumption can be difficult. This can be
due to small portion size, having a relatively large surface area
for radiating or absorbing heat and having a relatively small mass
that is insufficient to retain heat or the lack thereof. Further,
prior art food storage containers often suffer from inadequate
thermal insulative properties. Hot foods quickly become warm or
cool and cold foods melt or warm up. Air may be exchanged across a
container-lid boundary leading to degradation of the food quality
or, worse, contamination. A user's enjoyment of the stored foods is
thus inhibited, and the desired freshness may be diminished.
[0005] What is needed is a food storage container and lid having
improved thermal and atmospheric sealing performance.
BRIEF SUMMARY OF THE INVENTION
[0006] The below summary is merely representative and
non-limiting.
[0007] The above problems are overcome, and other advantages may be
realized, by the use of the embodiments.
[0008] In a first aspect, an embodiment provides a double wall
vacuum insulated food container with insulated lid that offers
superior performance in terms of thermal transfer and atmospheric
sealing. The container includes a body portion and a lid portion.
The body portion has, in a use configuration, a base or floor and
at least one upwardly extending side wall terminating in an upper
free edge. The at least one wall may be round, oval, rectangular,
square, or any other desired shape. The container comprises an
inner portion and a complementary outer portion, there being an air
gap in between the two for improved thermal performance. The air
gap may be maintained as a vacuum, at low pressure, filled with
air, or filled with a preferred gas or combination of gases, or
some combination thereof. In one non-limiting embodiment, the air
gap may also be filled with a foam insulation. In a preferred
embodiment, the container is formed of stainless steel.
[0009] A complementary lid portion is configured to sealingly fit
onto the upper free edge of the container. The lid comprises a
central substantially planar member and a surrounding frame with
sealing ring. The planar member is provided with enhanced thermal
characteristics. For example, the planar member may have an upper
portion and a lower portion, each being peripherally joined,
substantially mutually parallel, and having an air gap there
between. The surrounding frame is configured to mechanically
receive the planar member there within. The sealing ring serves as
an interface between a lower peripheral edge of the frame and an
upper free edge of an underlying container. The frame is preferably
provided with plural fastening members adapted to selectively
engage with complementary features disposed about the upper free
edge of the container. In one embodiment, the frame is provided of
metal or plastic and the fastening members are connected to the
frame, such as through the use of a living hinge.
[0010] Selectively disposed within the container is at least one
separator having an outer profile substantially complementary with
an inner contour of the container, whereby the interior of the
container may be selectively divided by a user.

DETAILED DESCRIPTION OF THE INVENTION
[0044] This patent application claims priority from U.S.
Provisional Patent Application No. 62/623,206, filed Jan. 29, 2018,
the disclosure of which is incorporated by reference herein in its
entirety.
[0045] FIGS. 1 and 5 depict a double wall vacuum insulated food
container 10 with insulated lid 14, according to the present
disclosure. The container 10 comprises a body portion 12 and an
insulated lid portion 14 configured to sealingly mate with the body
portion 12.
[0046] With respect to FIGS. 3, 4, 7, and 8, the body portion 12,
in a use configuration, has a base or floor 16 and at least one
upwardly extending side wall 18 terminating in an upper free edge
20.
[0047] Preferably, the upper free edge 20 is equidistant from the
base 16 along all points about the container 10. However, in
certain embodiments, it may be desirable to have one or more
discontinuities or regions where the distance from the base 16 to
the upper free edge 20 is not uniform.
[0048] The at least one upwardly extending side wall 18 can be
provided in a variety of vertical projections, including round,
oval, square, rectangular, or other geometries. For example, there
may be four such walls 18 arranged in the shape of a square with
two pairs of oppositely facing, mutually parallel walls, as
depicted in FIGS. 5-8 and 20-29. In particular, with respect to
FIG. 28, the length and width, dimensions L and W, are equal. In an
exemplary embodiment, L and W equal 176 mm and the container
height, dimension H, equals 81 mm. Alternatively, there may be four
such walls 18 arranged in the shape of a rectangle with two pairs
of oppositely facing, mutually parallel walls 18, as depicted in
FIGS. 1-4 and 9-19. In particular, with respect to FIG. 18, the
length is 176 mm and the width is 126 mm, while the container
height is 81 mm. The transitions between adjacent walls 18 and
between the base 16 and the side walls 18 in all configurations may
be ninety degrees or rounded (as illustrated) with a desired
radius.
[0049] The body portion 12 in a first embodiment is provided of
stainless steel due to its superior cleanability and thermal
qualities. An outer surface of the container 10, when provided of
stainless steel, may be polished or brushed, the latter enabling
easier gripping, particularly in damp or wet environments. In the
first embodiment, the stainless steel is 0.5 mm thick.
[0050] In one embodiment, the floor 16 is flat and featureless.
However, in other embodiments, the base 16 may be provided with
linear or discrete features 26 (FIGS. 3 and 7) which may resist a
tendency for the container 10 to adhere to or slide along a wet
surface such as a kitchen counter. Such features 26 provided on the
bottom of the container 10 may also be configured to fit
cooperatively with complementary features on the top of a
corresponding lid 14 (not shown) to facilitate vertical stacking of
body/lid units. Such features 26 may also include downward
projections on the container floor 16 and/or complementary recesses
on the lid 14 upper surface. Further, the floor exterior surface
may also have a depression or aperture 48 used to evacuate air
during the manufacturing process, as shown in FIGS. 3 and 7. Once
the space between the inner wall 22 and the outer wall 24 is
evacuated, in an illustrated embodiment, the aperture 48 is
plugged. For purposes of presentation, the sealed aperture 48 may
be covered, as with a cap or cover 49.
[0051] Preferably, the body portion 12, including the floor 16 and
at least one side wall 18, is comprised of an inner wall 22 and an
outer wall 24 (FIGS. 3, 7, 19, and 29), each of which are
substantially mutually parallel and joined at the upper free edge
20. The space between the inner and outer walls 22, 24 is evacuated
in a first embodiment to create a vacuum to improve the resistance
to thermal transfer of the body portion 12. In combination
therewith or in the alternative, the space between the inner and
outer walls 22, 24 may contain a low-pressure quantity of air
and/or one or more desired gases.
[0052] At the upper free edge 20 of the body portion 12, the outer
wall 24 forms an outwardly projecting shoulder 30, as seen at least
in FIGS. 4, 8, 11, 14, 22, and 25. As will be described, this
shoulder 30 receives part of the lid portion 14 and prevents the
lid portion 14 from resting on the body portion 12 at an angle.
[0053] As shown with respect to the embodiments of FIGS. 2 and 6,
the lid portion 14 comprises a central substantially planar member
40 and a surrounding frame 42 with sealing member 44. The planar
member 40 may be completely flat and featureless, as shown in FIGS.
9, 10, 20, and 21. Alternatively, the planar member 40 may have a
variety of physical features formed therein for functional and/or
decorative purposes, such as seen in FIGS. 1 and 5. For example,
the planar member 40 may be provided with recesses that physically
complement downwardly projecting features 26 disposed on the outer
surface of the body portion floor 16, as previously described. Such
complementary features 26 may facilitate vertical stacking of
body/lid units.
[0054] The planar member 40 is preferably provided of stainless
steel due to its superior cleanability and thermal qualities. The
planar member 40 is also preferably hollow, having an upper surface
50, a lower surface 52, and a surrounding side wall 54 formed into
a single, hollow unit, as shown in FIGS. 19 and 29. The interior of
the planar portion 40 may be provided as a vacuum, may contain low
pressure air, and/or may contain one or more desired gases, to
enhance the resistance to thermal transfer through the lid portion
14.
[0055] About a lower edge of the periphery of the planar member 40,
at the juncture of the lower surface 52 and the side wall 54, is an
inwardly extending shoulder 56. This shoulder 56 preferably extends
continuously about the entire planar member 40.
[0056] The frame 42 may be formed of plastic or metal, though
plastic may be preferred in some embodiments due to its lower
weight, pliability and resistance to denting, and ability to be
provided in a variety of colors. The frame 42 is preferably
provided with a substantially vertical, inwardly facing side wall
60 that forms a continuous enclosed space dimensioned to snugly
receive the planar member 40. Formed at a lower extent of the side
wall 60 is an inwardly projecting shelf 62 dimensioned to
complement the dimensions of the inwardly extending shoulder 56 of
the planar member 40. The inwardly extending shoulder 56 of the
planar member 40 thus rests on the inwardly projecting shelf 62 of
the frame 42 and is retained there through interference fit in a
first embodiment. In alternative embodiments, the planar member 40
is retained within the frame 42 via gluing, welding, and/or
mechanical features or means.
[0057] As shown in FIGS. 9-11 and 20-22, the frame 42 is provided
with a plurality of peripherally disposed clasps 70. In the
illustrated embodiments, there is one clasp 70 associated with each
of the at least one side walls 18. Thus, in the depicted
embodiments, there are a total of four clasps 70. Preferably, each
clasp 70 extends laterally across a portion of the frame 42. As
illustrated in FIGS. 11 and 22, the clasps 70 are attached to the
frame 42 via a hinge 72. The hinge 72 in a first embodiment is a
plastic living hinge. Other, more complex hinges, such as flag
hinges or piano hinges, may be employed, though with added
complexity and increased difficulty in maintaining cleanliness.
[0058] In a first, rest position, shown in FIGS. 10 and 21 and on
the left side of FIGS. 11 and 22, the clasps 70 may extend
outwardly from the lid portion 14 about the respective hinge 72. In
a second, engaged position, shown in FIGS. 9 and 20 and on the
right side of FIGS. 11 and 22, each clasp 70 may be manually
manipulated into the engaged position in which the respective clasp
70 extends substantially vertically, adjacent the lid portion 14
and the body portion 12. On an inner side of the clasp 70, most
proximate the body portion 12 when the lid portion 14 is mounted
thereon, the clasp 70 has a prong 76. When the clasp 70 is in the
engaged position, the prong 76 projects upward at an angle from the
clasp 70. As seen in FIG. 30, with the respective clasp 70 angled
around the hinge 72 to the engaged position, the prong 76 extends
slightly upwardly, forming an oblique angle 78 with respect to a
portion of the clasp 70 below the prong 76 (indicated by a dashed
arc) and forming an acute angle with respect to a portion of the
clasp 70 above the prong 76 (also indicated by a dashed arc). Thus,
when the lid portion 14 is lowered onto the body portion 12, the
lower surface of the prong 76 may deflect away from the outwardly
projecting shoulder 30 atop the upper free edge 20 of the outer
wall 24. Once the lid portion 14 is fully seated on the upper free
edge 20, as discussed subsequently, the clasp 70 may be manually
urged into the engaged position, which by an upwardly projecting
point 82 of the prong 76 contacts a lower surface of the outwardly
projecting shoulder 30, effectively restraining upward vertical
movement of the lid 14. The clasp 70 is removed from the engaged
position by a user inserting one or more fingers on a lower extent
of the clasp 70 and/or on an inside edge of the lower extent of the
clasp 70 and pulling outwardly. The upwardly projecting point 82 of
the prong 76 is thus removed from engagement with the outwardly
projecting shoulder 30 and the clasp 70 may swing or be swung about
the hinge 72 to the rest position. Note that in the illustrated
embodiment the clasp 70 has a substantially vertical upper portion
90 and an angled lower portion 92 that is angled slightly
outwardly, opposite the respective prong 76. Such a configuration
enhances the ability of a user to engage the clasp 70 when moving
it from the engaged position to the rest position. In an
alternative embodiment, the clasp 70 is substantially planar.
[0059] The prong 76 associated with each clasp 70 may be a discrete
element that has a narrow width with respect to the respective
clasp 70. Alternatively, the prong 76 may have a width that is a
greater percentage of the width of the respective clasp 70, all the
way up to 100% of the respective clasp width. In the embodiments of
FIGS. 13 and 24, the prongs 76 are seen to extend over a major
length of the respective clasp 70.
[0060] The lower extent of the frame 42 is provided with a
peripheral, downwardly facing channel 94, as seen in FIGS. 3 and 7.
Disposed within the channel 94 is the sealing member 44, which in a
first embodiment is provided of silicone, though other pliant,
resilient materials may be employed. Thus, as viewed in FIGS. 3 and
7, when the lid portion 14 is disposed atop the body portion 12,
the sealing member 44 rests on top of the upper free edge 20 of the
at least one side wall 18. Preferably, a user applies downward
force on the lid portion 14 in order for the upwardly projecting
point 82 of the prongs 76 associated with each clasp 70 to fit
beneath the outwardly projecting shoulder 30 atop the upper free
edge 20 of the outer wall 24. The sealing member 44 thus deforms
slightly, forming an airtight seal with the upper free edge 20.
Once the clasp 70 is returned to the rest position and the lid
portion 14 is removed from the body portion 12, the sealing member
44 returns to an uncompressed shape.
[0061] Optionally, the food container 10 may include a body portion
divider 100a, 100b (FIGS. 2 and 6). For ease of cleaning and for
reduced cost, the divider 100a, 100b is preferably provided in
plastic. Each divider 100a, 100b includes a pair of parallel,
vertically extending end walls 102 and a vertical intermediate wall
104 disposed between and orthogonal to the respective end walls 102
(FIGS. 4 and 8). The dimensions of the divider 100a, 100b depend in
part upon the dimensions of the respective body portion 12 and in
part upon how the divider 100a, 100b is to cooperate with respect
to the body portion 12.
[0062] For example, the divider 100a is configured to extend across
a width of the respective body portion 12. The end walls 102 are
planar. Both the end walls 102 and the intermediate wall 104 are
dimensioned in this embodiment to span the width of the body
portion 12, as seen in FIG. 15. Preferably, the intermediate wall
104 is long enough so that the divider 100a is installed and
retained in the body portion 12 through a friction fit, such as
seen in FIG. 16. However, the fit enables the divider 100a to be
moved along the length dimension of the body portion 12 according
to the needs of the user, as seen in FIG. 17. Also visible in this
embodiment is a divider bottom wall 106 that substantially lies in
a horizontal plane, orthogonal to the intermediate wall 104. Once
installed in the respective body portion 12, the bottom wall 106
lies flush against the floor 16.
[0063] In another embodiment, the divider 100b is configured and
dimensioned to fit vertically, on the diagonal between opposite
corners of a four-sided body portion 12, such as the square body
portion 12 seen in FIGS. 26 and 27. The end walls 102 are curved to
complement the interior curvature between the at least one side
walls 18. The divider 100b is also provided with a bottom wall 106.
Once inserted, the divider 100b effectively separates two halves of
the body portion 12.
[0064] FIGS. 31 and 32 show a view of a further embodiment of a
container 200. In this embodiment, the container 200 has a body 212
and a lid 214. The lid 214 includes a pressure release valve 235.
When hot foods are placed inside the container 200 and the lid 214
is sealed the heat can cause a pressure differential between the
interior and exterior atmospheres. This can make separating the lid
214 from the body 212 difficult. By pressing the pressure release
button 235, the interior container atmosphere is equalized to the
exterior atmosphere, allowing the lid 214 to be easily removed from
the container body 212.
[0065] The foregoing description has been directed to particular
embodiments. However, other variations and modifications may be
made to the described embodiments, with the attainment of some or
all of their advantages. Modifications to the above-described
systems and methods may be made without departing from the concepts
disclosed herein. Accordingly, the invention should not be viewed
as limited by the disclosed embodiments. Furthermore, various
features of the described embodiments may be used without the
corresponding use of other features. Thus, this description should
be read as merely illustrative of various principles, and not in
limitation of the invention.
