FIELD OF THE INVENTION
The present invention generally relates to a colander. More specifically, the present invention relates to a colander including an outer shell having a screen with an open top, an upper rim, and a bottom frame with a rotatable inner screen disposed thereon. The colander further includes an annular base rotatably coupled to the bottom frame to provide an open and closed configuration for the sieve.
BACKGROUND OF THE INVENTION
Colanders are a popular kitchen utensil that allows users to drain liquid and rinse food. Some of the most common reasons for the use of colanders or strainers, are for rinsing contaminants from fruits and vegetables, and draining the cooking fluids used with pasta and other items. Typically, the conventional colanders have allowing the contents within the colander to be suspended above the basin of a sink, thereby allowing water and other fluids to be drained and disposed. The colander is also particularly beneficial for preventing contamination of the contents therein.
In addition, many individuals employ the use of colanders when rinsing and draining foodstuff. Because colanders generally have a plurality of holes throughout, food particles easily become stuck and trapped therein. This can be difficult to dislodge and can result in an unclean colander that becomes unproductive over time. People often scrape at the food particles along the sides and bottom of the colander through the use of their hands, which often leads to injuries and contamination. Therefore, it would be advantageous to have a colander that is easy to clean and provides movable parts for dislodging food particles therefrom. It would also be advantageous to have a colander that could be placed in a kitchen sink without contacting the bottom of the sink basin, and that functions properly and robustly in the kitchen sink independent of varying sink or faucet dimensions.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of colanders now present in the prior art, the present invention provides a new and improved colander wherein the same can be utilized for providing convenience for the user when draining water from food.
It is therefore an object of the present invention to provide a new and improved colander that has all of the advantages of the prior art and none of the disadvantages.
Therefore, it is an object of the present invention to provide a colander comprising an outer shell including a screen having an open top, an upper rim, and a bottom frame. The outer shell includes perforations throughout such that water or other liquids can escape therethrough. The upper rim includes at least two handles thereon.
It is yet another object of the present invention to provide a colander including a circular inner screen disposed on the bottom frame of the colander. The inner screen is rotatable via a pivot pin located at the center of the bottom frame. The circular inner screen comprises a first section and a second section that can rotate about the pivot pin.
It is another object of the present invention to provide a colander including an annular base rotatably coupled to the bottom frame to provide an open and closed configuration for the sieve. The annular base can be rotated to provide an opening in the bottom frame of the colander.
Another object of the present invention is to provide a colander that may be readily fabricated from materials that permit relative economy and are commensurate with durability.
Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the colander. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for draining water from food. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.
Referring now to FIG. 1, there is shown a side cross-sectional view of the colander according to one embodiment of the present invention. The colander 100 includes an outer shell 102 comprising a screen having an upper rim 106 forming an open top 104, and a bottom frame 108. The outer shell 102 is substantially bowl-shaped. The outer shell 102 includes a plurality of perforations throughout so as to allow for draining water and other liquids therefrom. The outer shell 102 has a structure which allows suspending the contents therein above the basin of a sink into which the rinse water or other liquid is to be drained to facilitate disposal of the liquid and prevent contamination of the contents. The colander 100 further includes an annular base 114, which rests on the bottom of the sink basin while the contents in the outer shell 102 are suspended above.
The upper rim 106 of the outer shell 102 further comprises at least two handles 122. Each handle 122 is an L-shaped handle, wherein one portion is flush against the upper rim 106 and a second portion extends perpendicularly from the first portion. The handles 122 are removably attached to the upper arm via a fastener. The fastener is preferably a snap on connection that attaches to the upper rim 106. In a preferred embodiment, the at least two handles 122 include finger holes such that user can insert his or her fingers therethrough to grasp the handle 122.
The bottom frame 108 of the outer shell 102 includes a circular inner screen 110 disposed thereon. The inner screen 110 is rotatable via a pivot pin 112 located at a midpoint of the inner screen 110. The inner screen 110 is configured to separate wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net. The annular base 114 is rotatably coupled to the bottom frame 108 to provide an open and closed configuration for the inner screen 110. In this way, the inner screen 110 can be opened to allow a user to gain access to the interior volume of the colander 100.
Referring now to FIGS. 2 and 3, there are shown views of the rotatable inner screen of the colander according to one embodiment of the present invention. The inner screen 110 includes a first section 118 and a second section 120 pivotally attached to one another via a pivot pin 112. In an open configuration, the first section 118 slides underneath the second section 120 in a stacked arrangement. In some embodiments, the circular inner screen 110 include guide rings or equivalent structure, which are supported upon rolls and enable rotation of the circular inner screen. Rotation of the circular inner screen 110 is accomplished by rotating the base 114 through the intermediary of a pivot pin 112 which is secured at the center of the inner screen 110.
The bottom frame 108 surrounds the periphery of the inner screen 110. The bottom frame 108 includes a vertical tab 128 on opposing ends on the bottom frame 108. The vertical tab 128 enables a user to selectively remove the inner screen 110 from the colander 100. The bottom frame 108 includes at least two guide rings 130 that enables rotation of the circular inner screen. The annular base is coupled to each guide ring 130 such that rotation of the base enables movement of the inner screen 110 in an open and closed configuration. The base serves as a pedestal and as a means of opening a portion of the inner screen 110 of the colander 100 when twisted or pivoted. The user can rinse food particles from the colander 100 via the opening formed when the inner screen 110 is placed in an open position.
It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
