Description

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 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 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.

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, 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.
FIG. 2 is a block diagram of a top view of a versatile container lid 100, in accordance with an embodiment of the invention. The lid 100 has a diameter D1 (or dimension D1) between the edge portion 135 and is circular in shape or substantially circular in shape. The diameter D1 may be set at any suitable length, so that the lid 100 may have different sizes for covering any variety of sizes of bowls.
As will be discussed below, in other embodiments of the invention, the lid 100 may have other shapes.
FIG. 3 is a block diagram of a bottom view of a versatile container lid 100 of FIG. 2, in accordance with an embodiment of the invention. The vertical walls 122a, 122b, 124a, and 124b are circular-shaped walls that are part of the lid body 130. The vertical wall 122a has a diameter of D2 and the vertical wall 122b has a diameter of D3, where D1>D2>D3.
The vertical wall 124a has a diameter of D4 and the vertical wall 124b has a diameter of D5, where D1>D2>D3>D4>D5 and 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 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-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 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 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.

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 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 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 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.

In an embodiment of the invention, the lid 1200 (or lid 100 or other embodiments of the lid disclosed herein) 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 1200 (or lid 100 or other embodiments of the lid disclosed herein) may be foldable and, 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 1200 (or lid 100), or other embodiments of the lid disclosed herein 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.
In an embodiment of the invention, a bendable portion of the lid 1200 (or lid 100 or other embodiments of the lid 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-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 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 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 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 those skilled in the relevant art(s) for setting the characteristics of silicone may be used in the bendable portion. In an embodiment of the invention, other portions of the lid 1200 may be formed from the same material that forms the bendable portion.
In an embodiment of the invention, the surface 1503 and .surface 1223 of the lid 1200 are bendable portions as described above.
Those skilled in the art will realize, after reading the discussion herein, that other suitable materials or combination of suitable materials can be used for the components in the lid 1200. 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 1200 may be selectively varied based on cost, ease of manufacturing, or/and other considerations. Additionally, the parts or components in the lid 1200 can be suitably varied or substituted with other parts or components or shapes, as manufacturing and parts technologies improve in the future.
