1. Field of the Disclosure
The present invention relates generally to storage containers, and more particularly to a lid assembly for a storage container.
2. Description of Related Art
Large size storage containers, such as Rubbermaid's Brute container products, are well known for use in collecting trash, yard waste, and the like. However, such large sized containers are sometimes used in commercial kitchens as a bulk food or bulk ingredient storage container. In one example, bakeries and the like utilize a high volume of ingredients on a regular basis. The various ingredients may be stored in bulk in these types of large volume containers. Although such containers are approved for food storage, a typical container of this type includes a standard, one-piece, opaque lid that does not promote safe and productive handling of ingredients when compared to other types of ingredient storage products.
In one example, such containers do not employ a lid storage feature of any kind. This can lead to inefficient work flow. A kitchen worker is frequently required to find a safe and clean place to store the lid when removing ingredients or refilling the container. If the lid is not stowed in a clean, safe location, there is a risk of cross-contaminating the food stuff stored in the container.
In another example, these types of storage containers typically do not have a scoop storage feature. This can often lead to improper storage of a portioning scoop. The scoop is often stored either on top of the lid or inside the container directly in the ingredients. These storage methods can also lead to cross-contamination of the stored food stuff. If stored on top of the lid, the scoop can become contaminated by touching the lid's outer surface. If stored in the ingredients, the kitchen worker will have to reach into and touch the ingredients each time the scoop is retrieved, creating a potential cross contamination risk. In addition, when the scoop is stored directly in the ingredients within the container, it can become more difficult to reach as the fill level is reduced.
In a further example, a typical container of this type has an opaque side wall and an opaque lid. Thus, there is no visibility into the container when the lid is attached. Since the entire container is opaque, a kitchen worker may have difficulty quickly identifying the particular ingredients in each container when taking inventory or when a particular ingredient is needed. The worker will have to remove the lid to identify the particular type of ingredients stored in the container and to determine the fill level within the container. This can further lead to work flow inefficiency within the kitchen environment.
There are a number of manufacturers, including Rubbermaid, Cambro, Carlisle, Continental, and the like that manufacture specific types of food ingredient bins that are particularly configured for storing food ingredients. These bins generally offer safe, clean, and productive, relatively efficient ingredient storage. However, these types of containers are specialized and, thus, can be relatively expensive. These types of containers are also typically not particularly large for high volume, bulk food storage needs.
A lid assembly is disclosed herein for a storage container base having an interior storage space and an open top end. In one example, a lid assembly according to the teachings of the invention has a closure section that is positionable over the open top end of the base. The closure section has a top panel, an access opening through the top panel or formed by the top panel with the closure section installed on the storage container, and a perimeter extending around at least a portion of the closure section. The perimeter can be removably attachable to the base open top end of the base. The lid assembly also has a hub and a cover section mounted to the closure section and rotatable about the hub between a closed position covering the access opening and an open position uncovering the access opening.
In one example according to the teachings of the invention, the cover section of a lid assembly can have a transparent part that can be positioned over the access opening in the closed position.
In one example according to the teachings of the invention, a perimeter of the closure section can be circular.
In one example according to the teachings of the invention, a perimeter of the closure section can be a continuous circular perimeter and the access opening can be formed through the top panel within the perimeter.
In one example according to the teachings of the invention, a lid assembly can have a continuous lip that extends around a perimeter of the access opening and protrudes upward from the top panel.
In one example according to the teachings of the invention, a lid assembly can have a lip that is adjacent and extending along the entirety of an edge of the top panel that forms the access opening. The lip can protrude upward from the top panel.
In one example according to the teachings of the invention, the hub of the lid assembly can have a boss that protrudes from one of the closure section and the cover section. A receiver can have an open entry and a hollow interior on the other of the closure section and the cover section. The boss can be fitted within the hollow interior through the open entry and permit relative rotation between the boss and the receiver about a hub axis.
In one example according to the teachings of the invention, the hub can have a boss that protrudes upward from the top panel of the closure section and an open entry into a receiver that can be on the underside of the cover section.
In one example according to the teachings of the invention, the entire cover section can be transparent.
In one example according to the teachings of the invention, the closure section can be formed of an opaque material.
In one example according to the teachings of the invention, a lid assembly can have a stop flange that extends circumferentially around and protrudes radially outward from the closure section, the perimeter of which can define a circle. The lid assembly can also have a catch flange that extends along at least one edge of the cover section and protrudes radially outward therefrom. The catch flange and stop flange can be configured and positioned to overlie one another and retain the cover section attached to the closure section in both the open and closed positions.
In one example according to the teachings of the invention, the cover section can be mounted on top of the closure section. The closure section can have a stop flange that is positioned directly above a catch flange on the cover section.
In one example according to the teachings of the invention, the cover section can be configured to drop down and register with part of the closure section in the closed position. A gap can exist between a stop flange on the closure section and a catch flange on the cover section in the closed position.
In one example according to the teachings of the invention, the cover section can be configured to drop down and register with part of the closure section in the open position. A gap can exist between a stop flange on the closure section and a catch flange on the cover section in the open position.
In one example according to the teachings of the invention, a gap can exist between a stop flange on the closure section and a catch flange on the cover section in the open and closed positions. The cover section can be raised until the catch flange contacts the stop flange. The cover section can be configured to rise, reducing the gap size, while being rotated between the open and closed positions.
In one example according to the teachings of the invention, the hub can define a generally vertical axis about which the cover section can rotate between the open and closed positions.
In one example according to the teachings of the invention, a lid assembly can have a bumped up region protruding upward on the closure section and can have a corresponding depression formed upward on an underside of the cover section. The bumped up region can be configured to register and nest with the corresponding depression with the cover section in the open position.
In one example according to the teachings of the invention, a lid assembly can have a ramped surface that lies between a bumped up region on the top panel of the closure section and the access opening.
In one example according to the teachings of the invention, an edge of the cover section, in the closed position, can lie at a base of a ramped surface that is positioned between a bumped up region on the top panel of the closure section and the access opening.
In one example according to the teachings of the invention, the cover section and the access opening can each have a generally semi-circular shape.
In one example according to the teachings of the invention, a storage container can have a base and a lid assembly. The base can have a bottom, a side wall, an interior storage space, and an open top end. The lid assembly can be removably attached to the open top end of the base. The lid assembly can have a closure section positioned over the open top end. The closure section can have a top panel, an access opening through the top panel, and a lid skirt coupled to the base and extending around the closure section. The lid assembly can also have a hub and a cover section mounted on the closure section and rotatable about the hub between a closed position covering the access opening and an open position exposing the access opening. An annular stop flange can protrude outward from and extend around the perimeter of the lid skirt. An annular catch flange can protrude outward from an outer edge of the cover section. The catch flange can be spaced directly below the stop flange in the open and closed positions to retain the cover section connected to the closure section.
Objects, features, and advantages of the present invention will become apparent upon reading the following description in conjunction with the drawing figures, in which:
The disclosed lid assembly of the invention solves or improves upon one or more of the above-noted and/or other problems and disadvantages with prior known storage containers. In one example, a lid assembly disclosed herein has a closure section and a movable cover section, which can be opened or closed relative to an access opening formed through or created by the closure section. In one example, the cover section can be clear or transparent in order to inspect the interior of the container with the lid closed. In one example, the lid assembly has a raised lip surrounding the access opening to prevent liquid spilled onto the lid assembly from entering the storage space of the container. In one example, the lid assembly can provide one or more scoop storage options that inhibit cross-contamination of food or other product stored in the container. In one example, the disclosed lid assembly need not be removed from the container in order to access the interior storage space.
Turning now to the drawings,
As will become evident to those having ordinary skill in the art upon reading this disclosure, the configuration and construction of the base 24, including the bottom, side wall 26, rim 30, stepped out region 34, handles 32, and the like, can vary within the spirit and scope of the present invention. Though the base 24 is disclosed herein as being essentially a tapered circular cylinder, the shape and configuration of the base can vary from the disclosed example. The base cross section can be square, rectangular, oblong, elliptical, or the like and yet function adequately in accordance with the teachings of the invention. The height of the base and its storage capacity can also vary. Based on the construction of the lid assembly 22, described in greater detail below, a generally circular configuration may perform or function better than other base shapes and configurations. However, these other shapes and configurations are within the spirit and scope of the present invention. Further, the base 24 can be formed using any suitable process and from any suitable material. In one example, the base can be a molded component and formed of a plastic or thermoplastic material inclusive of thermoplastic elastomer, polypropylene, polyethylene, ABS, or the like.
With reference to
The closure section 40 in this example also includes or defines an access opening 48 through a portion of the top panel 44. In the disclosed example, the access opening 48 is generally a half-circle shape and is sized to be about, but a little less than, half of the area of the closure section 40. As will be evident to those having ordinary skill in the art, the size and position of the access opening 48 can vary from the example shown and described herein. For example, if the closure section 40 had a discontinuous lid skirt and a missing segment, the access opening would not necessarily be formed through the top panel 44. Instead, the access opening would be formed or created by the missing segment adjacent an edge of the top panel with the closure section attached to the open top end 28 of the base 24. Such an access opening construction is within the spirit and scope of the present invention. However, in this example there is no discontinuous portion of the closure section 40 that does not contact the base 24 when attached. In the disclosed example the access opening 48 is formed through a portion of the top panel 44 because the perimeter structure of the closure section 40 is a continuous structure, as is the lid skirt 46.
In one example, the closure section 40 can be molded from an ABS plastic material using a suitable molding process. However, the closure section 40 can also be fabricated from other suitable materials and processes without departing from the spirit and scope of the invention. In this example, the closure section 40 has a pair of depending alignment tabs 49 that protrude down from the lid skirt 46. The tabs are sized and positioned to seat between the handle trusses 36 in this example. As discussed below, the lid assembly 22 can be secured to the base 24 via these tabs or the lid skirt can be configured to connect to and engage with the rim 30 to secure to the base.
With continued reference to
The cover section 42 also includes a partial cover skirt 58 carried on and depending from the curved portion 52 of the perimeter. A hub receiver 60 protrudes upward from the cover section 42 near the linear portion 50 of the perimeter and located centrally along the linear portion. A pair of upturned tabs 62 is carried on the edge of the linear portion 50 of the cover section 42. The tabs 62 are spaced from and flank the hub receiver 60. The hub receiver 60 in this example is open at its bottom end and upwardly hollow.
In one example, the entire cover section 42 can be formed of a clear or transparent material. In another example, a portion of an otherwise opaque cover section can include a clear or transparent window. In either case, the transparent aspect of the cover section 42 can provide advantages over prior art storage containers of this type, as is discussed below. In one example, the cover section 42 can be made from a polycarbonate material or the like. However, the material and process used to fabricate the cover section can vary within the spirit and scope of the present invention. The cover section 42, as with the closure section 40 and the base 24, is not intended to be limited to any particular material or manufacturing process.

As shown in
Various details of the lid assembly 22 will now be described with reference to
An annular stop flange 76 extends radially outward from and circumferentially around the lid skirt 46 on the closure section. A corresponding annular catch flange 78 protrudes radially inward from and extends circumferentially around the curved portion 52 on the cover skirt 58 of the cover section 42. With reference to
With reference to
The cover section 42 can be further rotated until it is positioned completely over the top panel 44 and exposes the entire access opening 48. The lid assembly 22 in this example can thus remain attached to the base 24 during use and regardless of whether the cover section 42 is open or closed. The cover section 42 in this example also has a semi-circular bumped up section 90 that corresponds in shape and size, though it is slightly larger, in comparison to the bumped up region 84 on the closure section 40. When the cover section 42 is completely open as shown in
When the cover section 42 is in the closed position of
As shown in
The lid assembly 22 disclosed here in is also shown having two optionally different scoop support features. In one example as shown in
In another example, a U-shaped elongate scoop hook 110 is integrally connected to the closure section 40. In this example, the hook 110 protrudes from the linear segment 54 within the access opening 48 as shown in
The scoops 104 and/or 110 can each be stowed within the container when not being used. Each of the scoops is positioned such that it can be readily grasped and retrieved upon opening the cover section 42. Each scoop is also stowed in a way that it does not require a user to dig the scoop out of the ingredients within the container. Cross-contamination can thus be reduced, minimized, or avoided.
As will be evident to those having ordinary skill in the art, the specific details of the base, lid assembly, scoops, and hooks can vary from those of the disclosed examples. Details of the lid hub can vary as well. The hub can include a snap or detent function whereby the cover section receiver snaps onto the closure section hub boss, while still allowing vertical movement as described above. It is possible that the hub be formed with a downward protruding structure instead of an upward protrusion of the disclosed example. The hub can be a more complex device, if desired, including the bearing or contact points between the cover and closure sections. The construction of the base rim and the various base and lid skirts, catches, stops, and other flanges can also vary from the examples shown.
In one alternate example, the lid assembly could have a unitary, conventional construction, but be clear or transparent or have a transparent window therein. The base and/or lid could be provided with a hanger allowing the lid to be removed from the base and then hung from the hanger. This would provide a solution to avoid lid cross-contamination during use. In such an example, a hook device could be provided that snaps onto the base for scoop management, lid management, or both. In another alternate embodiment, the cover section could be mounted beneath the closure section instead of on top of the closure section. Registration and nesting, relative vertical movement, and the like would still be possible, although some biasing device might be required to bias the cover section upward in order to register and nest in the open and/or close positions.
Although certain lid assemblies and features have been described herein in accordance with the teachings of the present disclosure, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all embodiments of the teachings of the disclosure that fairly fall within the scope of permissible equivalents.
