This invention relates in general to collapsible containers, such as for temporary food storage.
Bowls, containers and perforated strainers, known in the food preparation art as colanders, are conventional kitchen items, typically formed of a rigid or semi-rigid material, that are self-supporting and have a comparatively fixed volume construction. While it is well-recognized that these tools offer many advantages, such as an ability to store or to be filled with a wide variety of content or foodstuffs and to generally remain their shape configuration, a drawback of all these conventional kitchen tools is that their form requires significant storage space, and thus are difficult to store.
The present invention provides for an easy-to-use and convenient-to-store combination of kitchen tools that can be readily and fully flattened or axially collapsed to a minimum size when not in use, expanded for use and be self-supporting when placed on a surface.
The combination of kitchen tools provided by the present invention includes a bowl, a food storage container and a colander, with the added benefit of axially-collapsing to a smaller, more efficient size. The space-saving and multi-application features of the present invention are particularly useful, for example, for storage, in kitchens with minimal storage area and dishwasher cleaning.
According to one form of the present invention, a collapsible colander and bowl includes an upper rim that defines an opening, a perforated bottom panel, a sidewall having an upper end secured to the upper rim and a lower end secured to the perforated bottom panel, a removable top lid designed to be attached to the upper rim, and a removable bottom lid designed to be attached to the perforated bottom panel. The sidewall of the collapsible colander and bowl is adjustable between a collapsed configuration and an expanded configuration.
In one aspect, the top and bottom lids are attachable and detachable in both the collapsed and expanded configurations. The sidewall is foldable from the expanded configuration to the collapsed configuration with at least five regions of the sidewall flexing and expandable from the collapsed configuration to the expanded configuration with the five regions forming at least a portion of the sidewall. The sidewall has a constant wall thickness extending from the upper rim to the perforated bottom panel.
In another aspect, the collapsed configuration of the sidewall is a low-profile configuration with five regions of the sidewall having three concave-up regions alternating with two concave-down regions. In the collapsed configuration, the perforated bottom panel is elevated above the lowermost points of the three concave-up regions. Also, in the collapsed configuration, a top surface of the perforated bottom panel is generally coplanar with an uppermost point of an outermost concave-down region of the sidewall.
In yet another aspect, a top surface of the upper rim includes an upwardly-extending double-ridge formation providing a mounting and sealing surface for the top lid. A bottom surface of the top lid includes a downwardly-extending ridge configured to interlock with the mounting and sealing surface of the upper rim. The bottom lid includes a larger surface area than a surface area of the perforated bottom panel and an upwardly-extending flange confining the surface area of the bottom lid such that the bottom lid is designed to snugly or tightly engage the perforated bottom panel.
In a further aspect, the upper rim and the top lid each have a pair of laterally-extending handle portions with corresponding openings to facilitate manual gripping.
In still another aspect, the sidewall is made at least in part of silicone. The perforated bottom panel is generally planar and the upper rim, perforated bottom panel and sidewall are generally square-shaped with rounded corners.
Aspects of the present specification disclose an all-in-one combination of colander, bowl and container that is configured to flatten from a raised position to a collapsed position. The colander, bowl and container in the raised position are configured to retain food. The colander, bowl and container in the collapsed position is collapsed for storage, optionally with the top and bottom lids remaining attached for convenience.
These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.
Referring now to the drawings and the illustrative embodiments depicted therein, as best shown in
As best shown in
The top lid 18 is selectively attachable to the upper rim 12 to cover the opening 13, and the bottom lid 20 is selectively attachable at an underside of the perforated bottom panel 16 so that the collapsible colander and bowl 10 can be used as either a colander (when bottom lid 20 is removed), as a bowl (when bottom lid 20 is attached), or as a closed container (when both top and bottom lids 18, 20 are attached). Furthermore, the collapsible colander and bowl 10 is configured such that top and bottom lids 18, 20 may be either attached or removed in both the expanded and collapsed configurations, which allows for compact storage, while reducing the likelihood that the lids 18, 20 will become separated from the colander portion 15 and subsequently lost.
In the collapsed configuration (with top and bottom covers removed), colander portion 15 assumes a low-profile configuration, such as shown in

Turning now to
In the illustrated embodiment, colander portion 15 and bottom lid 20 are each generally square-shaped with rounded corners. Other shapes of the colander portion and/or the lids are also envisioned, such as circular, oval, or substantially any polygonal shape. Bottom lid 20, having an upwardly-extending perimeter flange 30 (
It should be understood that materials used for the collapsible colander and bowl 10 are preferably food-grade material(s) so that the collapsible colander and bowl 10 can be safely used with food items. Although sidewall 14 may be made of a silicone material so it is relatively flexible, various combinations of silicone and non-silicone materials that can be used to make sidewall 14 are also contemplated within the scope of the present invention.
As utilized herein, the term “flexible” is utilized to refer to materials which are capable of being flexed or bent, especially repeatedly, such that they are pliant and yieldable in response to externally applied forces. Accordingly, “flexible” is substantially opposite in meaning to the terms inflexible, rigid, or unyielding. Materials and structures which are flexible, therefore, may be altered in shape and structure to accommodate external forces and to conform to the shape of objects brought into contact with them without losing their integrity.
The preferred embodiments described herein thus provide for a collapsible colander and bowl that is extendable to an expanded configuration to selectively form a colander, bowl, or container and foldable to a nearly-flat collapsed configuration for storage.
Changes and modifications in the specifically described embodiments may be carried out without departing from the principles of the present invention, which is intended to be limited only by the scope of the appended claims, as interpreted according to the principles of patent law including the doctrine of equivalents.
The present application claims priority of U.S. provisional application Ser. No. 62/947,976, filed Dec. 13, 2019, which is hereby incorporated herein by reference in its entirety.
