Versatile Square Container Lid
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of and priority to
U.S. Provisional Application No. 62/129,734, filed May 26,
2015, and to U.S. Patent Application No. 14/838,529, filed
August 28, 2015.
TECHNICAL FIELD
Embodiments of the invention relate generally to a
versatile container lid.
BACKGROUND
A variety of food containers and corresponding lids are
available to consumers in various sizes, shapes (e.g., bowls,
box-shaped containers, and/or the like), and/or
configurations. Consumers often unnecessarily spend their
valuable time looking for a particular lid that fits into a
bowl or other container and/or often sift or search through a
pile of mismatched lids. In other words, the consumer is
often required to rummage through countless lids (or a
relatively high number of lids in the kitchen) in order to
find a lid that fits a particular food container.
Additionally, maintaining a large number of lids does
not allow the consumer to save space in the kitchen, kitchen
cabinets, and/or cupboards. Furthermore, the currently
available tin foil products and plastic wrap products may not
provide a sufficient air-tight cover for food containers, are
disposable products that may harm the environment, and/or
would add to the consumer's expense since new foil products
1
CA 02922300 2016-03-02
and/or plastic wrap products are disposable products that are
required to be re-purchased by the consumer. Therefore, some
consumers are frustrated with the requirement and
inconvenience of having to keep different sized lids that are
associated with different sized food containers and/or with
the unnecessary expense of purchasing disposable food
covers.
Various food container lids are disclosed in, for
example, the following patent-related publications: U.S. Pat.
No. 7,264,135, U.S. Pat. No. 8,007,615, US 2009/0183807, US
2010/0207297, and US D555,982. However, these conventional
products: (1) do not provide a sufficiently rigid cover, (2)
are not able to provide a cover for different sized food
containers, (3) require multiple parts that are subject to
wear-and-tear due to the frequent use of the food containers,
and/or (4) require particular shapes and/or configurations
that lead to additional manufacturing expenses and
complexities. Silicone sealing lids which are reusable and
safe for use in a refrigerator, freezer, and/or dishwasher
are also commercially available. However, any particular
silicone sealing lids is only usable for a corresponding
container size. Therefore, the conventional products have
various disadvantages that are not desirable for the
consumer.
Based on the above discussion, the current technology is
limited in its capabilities and suffers from at least the
above constraints and deficiencies.

FIG. 1 is a block diagram of a cross-sectional side view
of versatile container lid 100 (apparatus 100), in accordance
with an embodiment of the invention. The lid 100 includes a
base portion 105 and an upper portion 110 coupled to (or
integrated with) the base portion 105. In other embodiments
of the invention, the base portion 105 and upper portion 105
may be a single piece that forms the lid 100. Other
variations in the components of the lid 100 are possible in
other embodiments of the invention.
In an embodiment of the invention, an upper central
surface 115 (or top center portion 115) of the upper portion
110 is a flat surface 116 or a substantially flat surface
116. In another embodiment of the invention, the upper
central surface 115 may have another configuration, shape,
and/or characteristic such as a non-planar surface 117 which
is shown in dashed (phantom) lines. Although the exemplary
non-planar surface 117 is depicted in FIG. 1 as a hemisphere
configuration, those skilled in the relevant art(s) would
realize based on the discussion herein that the non-planar
surface 117 may have other shapes and/or configuration and/or
may be disposed in another position on any position on a top
surface 118 of the upper portion 110 and/or may be a single
element 117 and/or may be multiple elements 117 or any amount
or number of elements 117. The upper central surface 115 is
disposed within a top surface central area of the lid 100 and
is on the top surface of the lid body 130.
In accordance with an embodiment of the invention, the
lid 100 includes a plurality of rings (which are generally
9
CA 02922300 2016-03-02
referred herein as rings 120). In FIG. 1, the exemplary lid
100 includes the rings 120a and 120b, although the number of
rings 120 may vary in another embodiment of the invention. As
will be discussed below, a ring 120 is a hollow section
between ridges of the lid 100, and each ring 120 can
removably receive and removably attach (and/or removably
secure and/or removably couple) the lid 100 to a container as
will be discussed below. Two components are removably
attached (or removably coupled or removably secured) means
that two different components can be attached together or
detached apart. Therefore, the rings 120a and 120b are formed
by respective openings (or respective hollow portions) in the
solid body portion 130 (or solid body 130) of the lid 100. If
the rings 120a and 120b are circular, then the two rings 120a
and 120b will be concentric or substantially concentric. If
the rings 120a and 120b are non-circular (e.g., square or
rectangular), then adjacent portions of the rings 120a and
120b will be parallel or substantially parallel.
Otherwise stated, the plurality of rings 120 are formed
within the lid body 130 of the lid 100. One exemplary
plurality of rings 120 includes a first ring 120a that is
configured to removably receive a first container 600 (FIG.
6) having a first size D6 and a second ring 120b that is
configured to removably receive a second container 700 (FIG.
7) having a second size D8. As will be discussed below, the
lid 100 can include one or more additional rings among the
plurality of rings 120 so that the lid 100 also has a third
ring that is configured to removably receive a third
container (e.g., container 930a in FIG. 9A) having a third
size D10. The lid 100 can include one or more additional
rings.
CA 02922300 2016-03-02
The opening 121 in the ring 120a is between the upright
wall 122a (vertical wall 122a) and the upright wall 122b
(vertical wall 122b) which is opposite to the wall 122a. The
walls 122a and 122b are part of the lid body 130. The opening
121 is also below upper wall 122c which is above the walls
122a and 122b and is typically substantially perpendicular to
the walls 122a and 122b. The upper wall 122c is also part of
the lid body 130.
The opening 123 in the ring 120b is between the upright
wall 124a (vertical wall 124a) and the upright wall 124b
(vertical wall 124b) which is opposite to the wall 124a. The
walls 124a and 124b are part of the lid body 130. The opening
123 is also below upper wall 124c which is above the walls
124a and 124b and is typically substantially perpendicular to
the walls 124a and 124b. The upper wall 124c is also part of
the lid body 130.
In the exemplary lid 100, the ring 120a is disposed
between the ridges 125a and 125b and disposed within the lid
body 130, with the ridge 125a forming an outer edge portion
135 (or edge portion 135) that spans the circumference (or
that spans the outer edge) of the base 105. The ridges 125a,
125b, and 125c are also part of the lid body 130. The ring
120b is disposed between the ridges 125b and 125c, with the
ridge 125c disposed adjacent to (and/or is a part of) the
center portion 115 of the lid 100.
In an embodiment of the invention, the lid 100 may be
formed by any suitable rigid material or semi-rigid material
such as, by way of example and not by way of limitation,
plastic, rubber, and/or another suitable synthetic material.
In another embodiment of the invention as will be discussed
below in additional details, the lid 100 may be foldable and,
11
CA 02922300 2016-03-02
therefore, the lid is at least partly formed by a suitably
flexible material, substantially flexible material, or
foldable material such as, by way of example and not by way
of limitation, silicone (i.e., silicone rubber).
The lid 100 may be manufactured by standard
manufacturing methods known to those skilled in the relevant
art(s) such as, by way of example and not by way of
limitation, molding, stamping, extrusion processing, casting,
polymer foam processing and forming, and/or other standard
shaping processes of synthetic materials.

where the diameters D1, D2, D3, D4, and D5 may be set to any
suitable lengths so that the lid 100 can cover any container
of different sizes. The diameters D1 through D5 will be
12
CA 02922300 2016-03-02
discussed further below when the lid 100 is used to cover
different sized containers.
As shown in FIG. 3, the rings 120a and 120b are
substantially circular and are substantially concentric.
FIG. 4 is a block diagram of a top view of a versatile
container lid 100, in accordance with another embodiment of
the invention. The lid 100 has a length of Li and width of
Wl, where Li and W1 may be set at any suitable set to any
suitable length, so that the lid 100 may have different sizes
for covering any variety of sizes of containers. If L1=W1,
then the lid 100 will have a substantially square shape. If
Li does not equal W1 (e.g., L1>W1), the lid 100 will have a
substantially non-square shape or substantially rectangular
shape.
FIG. 5 is a block diagram of a bottom view of a
versatile container lid 100 of FIG. 4, in accordance with an
embodiment of the invention. The vertical walls 122a, 122b,
124a, and 125b are square-shaped walls that are part of the
lid body 130. The vertical wall 122a has a width (dimension)
of W2 and length (dimension) of L2, and the vertical wall
122b has a width (dimension) of W3 and length (dimension) of
L3, where W1>W2>W3 and L1>L2>L3. The vertical wall 124a has a
width (dimension) of W4 and length (dimension) of L4, and the
vertical wall 124b has a width (dimension) of W5 and length
(dimension) of L5, where L1>L2>L3>L4>L5 and W1>W2>W3>W4>W5,
and where the lengths Li, L2, L3, L4, and L5 and the widths
Wl, W2, W3, W4, and W5 may be set to any suitable lengths so
that the lid 100 can cover different sized containers.
The exemplary lid 100 is square in shape if W1=L1,
W2=L2, W3=L3, W4=L4, and W5=L5. The exemplary lid 100 is non-
13
CA 02922300 2016-03-02
square in shape or is rectangular in shape if at least W1
does not equal Ll.
As shown in FIG. 5, the vertical portions 502a of the
ring 120a and the vertical portions 504a of the ring 120b are
all substantially parallel. The horizontal portions 502b of
the ring 120a and the horizontal portions 504b of the ring
120b are all substantially parallel.
FIG. 6 and FIG. 7 will illustrate the versatile feature
of the lid 100. In particular, FIGS. 6 and 7 will illustrate
the adaptability or versatility of the lid 100 to function as
a cover for different sized containers (e.g., containers with
different diameters or different dimensions such as different
width dimensions). The containers 600 and 700 in FIGS. 6 and
7, respectively are, by way of example and not by way of
limitation, food containers or other suitable types of
containers used by the consumer in the kitchen or in the
home.
FIG. 6 is a block diagram of a cross-sectional side view
of a versatile container lid 100 removably coupled to a first
container 600 of a first size D6, in accordance with another
embodiment of the invention. The container 600 includes a
side wall 602 that forms (surrounds) an opening of size D6
(which could be a diameter D6 if the container 600 is
circular in shape or a width D6 if the container 600 is non-
circular such as a square-shaped container or rectangular-
shaped container). A rim 605 is formed at the end or top of
the side wall 602. The rim 605 is removably inserted into the
opening 121 of the ring 120a such that the rim side 606 will
push against the side wall 122a and the side wall 122a will
push against the rim side 606. Since the rim side 606 and the
side wall 122a will push against each other, the lid 100 (and
14
CA 02922300 2016-03-02
lid body 130) are removably secured on the container 600 and
provide a substantially sealed cover on the container 600.
The size D7 of the container 600 between the rim side 606
will be approximately equal to the size (dimension) D2 (for a
circular lid 100) or to the size (dimension) W2 (for a non-
circular lid 100) so that the side wall 122a and the rim side
606 will provide sufficient force against each other. The
size D7 is also greater than the size (dimension) D3 (for a
circular lid 100) or the size (dimension) W3 (for a non-
circular lid 100) so that the rim 605 is removably insertable
into the opening 121. The lid 100 is removably attached to
the container 600 by pressing the lid 100 in a downward
direction 610 toward the container 600 so that the rim 605 is
received by the opening 121 and the rim 605 is removably
contacting at least the side wall 122a of the ring 120a.
Typically, the top wall 122c is also in contact with the rim
605.
The lid 100 is detached from the container 600 by
pulling the lid 100 in the upward direction 615 away from the
container 600, so that the rim 605 is removed from the
opening 121 of the ring 120a. As a result, the lid 100 is
separated from the container 600.
FIG. 7 is a block diagram of a cross-sectional side view
of a versatile container lid 100 removably coupled to a
second container 700 of a second size D8, in accordance with
another embodiment of the invention. The container 700
includes a side wall 702 that forms (surrounds) an opening of
size D8 (which could be a diameter D8 if the container 700 is
circular in shape or a width D8 if the container 700 is non-
circular such as a square-shaped container or rectangular-
shaped container). A rim 705 is formed at the end or top of
CA 02922300 2016-03-02
the side wall 702. The rim 705 is removably inserted into the
opening 123 of the ring 120b such that the rim side 706 will
push against the side wall 124a and the side wall 124a will
push against the rim side 706. Since the rim side 706 and the
side wall 124a will push against each other, the lid 100 (and
body 130) are removably secured on the container 700 and
provide a substantially sealed cover on the container 700.
The size D9 of the container 700 between the rim side 706
will be approximately equal to the size (dimension) D4 (for a
circular lid 100) or to the size (dimension) W4 (for a non-
circular lid 100) so that the side wall 124a and the rim side
706 will provide sufficient force against each other. The
size D9 is also greater than the size D5 (for a circular lid
100) or the size W5 (for a non-circular lid 100) so that the
rim 705 is removably insertable into the opening 123. The lid
100 is removably attached to the container 700 by pressing
the lid 100 in a downward direction 710 toward the container
700 so that the rim 705 is received by the opening 123 and
the rim 705 is removably contacting at least the side wall
124a of the ring 120b. Typically, the top wall 124c is also
in contact with the rim 705.
The lid 100 is detached from the container 700 by
pulling the lid 100 in the upward direction 715 away from the
container 700, so that the rim 705 is removed from the
opening 123 of the ring 120b. As a result, the lid 100 is
separated from the container 700.
In another embodiment of the invention, the lid 100 is
foldable in the downward direction 720. As a result, when the
lid 100 is removably coupled to the container 700, folding
the lid 100 against the wall 702 will save space and will
allow the lid 100 to be stored in a relatively smaller area.
16
CA 02922300 2016-03-02
Therefore, the lid 100 advantageously provides saves room or
space in the kitchen, kitchen cabinets, refrigerators, and/or
cupboards. The foldable feature of the lid 100 will be
discussed below with reference to FIG. 8 in accordance with
another embodiment of the invention.
Referring to both FIGS. 6 and 7, the first container 600
is larger than the second container 700 because D7>D9 and
D6>D8. Therefore, the various rings 120 (e.g., rings 120a and
120b) are configured to removably receive different sized
rims of associated different sized containers and to allow
the lid 100 to be used as a cover for different sized
containers. The exemplary lid 100 can be used to cover a
relatively larger container 600 as shown in FIG. 6 and can
also be used to cover a relatively smaller container 700 as
shown in FIG. 6.
As will be discussed below, in other embodiments of the
invention, the lid 100 can include additional rings 120 so
that the lid 100 can also be used to cover other containers
that may have sizes that differ from the container 600 or
container 700.
FIG. 8 is a block diagram of a cross-sectional side view
of a foldable versatile container lid 800 (apparatus 800), in
accordance with another embodiment of the invention. The
foldable lid 800 may include at least some of the features
described above in the lid 100 such as, for example, a
plurality of rings that are formed within the lid body 130.
The lid 800 is removably attached to the container 700 in a
manner as similarly described above with respect to FIG. 7.
After the lid 800 is removably attached to the container 700,
the lid 800 is bent in a downward direction 805 so that the
bottom surface 810 of the bendable lid portion 815 is
17
CA 02922300 2016-03-02
adjacent to (and/or is in contact with) the external surface
820 of the container 700. The bendable lid portion 815 is a
part of the lid body 130 of the lid 800 and is disposed
between the center portion 115 (that includes portion 825
which is adjacent to the ring 120b) of the lid 800 and the
end portion 830 of the lid 800. The center portion 115,
portion 825, bendable portion 815, and end portion 830 are
part of the lid body 130. When the lid 800 is bent in the
downward direction 805, the portion 815 will not be parallel
to the portion 825 and center portion 115. By bending the
portion 815 in the downward direction 805, the lid 800 is
more compact, occupies less space, and can advantageously be
stored in a relatively smaller area.
The lid 800 can be bent in the upward direction 835 so
that the surface 810 is no longer adjacent with (and/or is no
longer in contact with) the surface 830. As a result, the
portion 815 will be substantially parallel to the portion 825
and center portion 115. The lid 800 can then be separated
from the container 700 that is currently removably attached
to the lid 800.
In an embodiment of the invention, the bendable portion
815 is formed from a substantially bendable material that
maintains the shape that is configured for the bendable
material. For example, the portion 815 may be formed from
silicone (or silicone rubber or polydimethlysiloxane) or
another suitable silicon polymer with rubber-like properties.
As known to those skilled in the relevant art(s), silicone
rubber is a polymer of silicon-containing carbon, hydrogen
and oxygen. Silicone rubber has excellent insulating and
temperature-resistant properties. Silicone rubber is made
through a process known as vulcanization or curing of natural
18
CA 02922300 2016-03-02
rubber. Silicon is injected into the long hydrocarbon chains
of natural rubber through a dual-stage process under high
heat and pressure, thus converting it into silicone rubber.
Additionally, the cured rubber is processed with additional
steps until the final marketable product is obtained.
Silicone rubber maintains all of its properties even at high
temperatures of approximately 300 degrees Celsius as well as
at low temperatures around -55 degrees Celsius. The silicon-
carbon bonds in silicone rubber are resistant to temperature
fluctuations. Additionally, silicone rubber exhibits better
tear strength, tensile strength, elongation and compression
in comparison to natural rubber at high temperatures. To
provide added rigidity to the portion 815 and decreased
elasticity to the portion 815, a suitable amount of sulfur is
added to the liquid rubber during the manufacturing process.
If rigidity is added to (and elasticity is decreased for) the
silicone used to form the portion 815, then the portion 815
can be bent in the downward direction 805 and the portion 815
will not automatically return back to its prior shape in the
upward direction 835, and/or the portion 815 can be bent in
the upward direction 835 and the portion 815 will not
automatically return back to a prior shape in the downward
direction 805. Other standard steps known to those skilled in
the relevant art(s) for setting the characteristics of
silicone may be used in the bendable portion 815. In an
embodiment of the invention, other portions of the lid 800
(such as, for example, the portion 825 and/or center portion
115) may be formed from the same material that forms the
portion 815.
Those skilled in the art will realize, after reading the
discussion herein, that other suitable materials or
19
CA 02922300 2016-03-02
combination of suitable materials can be used for the
components in the lid 100 (or other lids discussed herein
such as the lid 800). Those skilled in the art will also
realize, after reading the discussion herein, that the
assembly, manufacture, and/or construction of the components
of the lid 100 (or other lids discussed herein such as the
lid 800) may be selectively varied based on cost, ease of
manufacturing, or/and other considerations. Additionally, the
parts or components in the lid 100 (or other lids discussed
herein such as the lid 800) can be suitably varied or
substituted with other parts or components or shapes, as
manufacturing and parts technologies improve in the future.

disclosed herein) is formed from a substantially bendable
material that maintains the shape that is configured for the
bendable material. For example, the bendable portion may be
formed from silicone (or silicone rubber or
polydimethlysiloxane) or another suitable silicon polymer
with rubber-like properties. As known to those skilled in the
relevant art(s), silicone rubber is a polymer of silicon-

tear strength, tensile strength, elongation and compression
in comparison to natural rubber at high temperatures. To
provide added rigidity to the bendable portion and decreased
elasticity to the bendable portion, a suitable amount of
sulfur is added to the liquid rubber during the manufacturing
process. If rigidity is added to (and elasticity is decreased
for) the silicone used to form the bendable portion, then the
bendable portion can be bent in the downward direction and
the bendable portion will not automatically return back to
its prior shape in the upward direction, and/or the portion
29
CA 02922300 2016-03-02
815 can be bent in the upward direction and the bendable
portion will not automatically return back to a prior shape
in the downward direction. Other standard steps known to
