Description:
BACKGROUND OF THE INVENTION 
     The present invention relates generally to collection of organic materials, and more specifically, but not exclusively, to a countertop compost collector for storing kitchen organic waste. 
     As concern about landfill space increases, worldwide interest in recycling by means of composting is growing, since composting is a process for converting decomposable organic materials into useful stable products. Increasingly there is greater attention on the need for composting organic waste generated in households. 
     One significant drawback for collecting green waste in a household environment is that organic waste can begin to decompose quite rapidly. Traditionally, indoor/countertop storage solutions cover and seal the contents of a “garbage” pail which decreases the oxygen supply to the contents. Putting green waste into such an environment where oxygen is limited initiates a fairly rapid anaerobic decomposition. 
     It is this anaerobic decomposition that creates fluids, odors, and potentially toxic bacteria that prevent acceptance of countertop/in-house collection and storage of organic waste in preparation for composting. The anaerobic decomposition is further undesirable in that the process attracts flies and other pests which can spread disease, and it is better to avoid attracting such pests into a household. Additionally, the collection and management of in-home organic waste generally requires tools and procedures that can clash with desired design and aesthetic elements. 
     What is needed is a compost collector that permits aesthetic accumulation and storage of household organic waste that is more sanitary, less messy, and less odiferous. 
     BRIEF SUMMARY OF THE INVENTION 
     Disclosed is a compost collector and compost collection method that permits aesthetic accumulation and storage of household organic waste that is more sanitary, less messy, and less odiferous. The following summary of the invention is provided to facilitate an understanding of some of technical features related to household collection of green waste, and is not intended to be a full description of the present invention. A full appreciation of the various aspects of the invention can be gained by taking the entire specification, claims, drawings, and abstract as a whole. 
     An organic material collection container for use with a collection bag, including, a continuous substantially vertical side wall, the side wall defining a volume generally matching a volume of the collection bag, the volume having a top opening and a bottom opening, the side wall having an inner wall with a plurality of substantially vertically-extending support ribs provided on the inner wall defining a plurality of vertically-extending chutes; a bottom joined to the side wall and closing the bottom opening, the bottom including one or more spacers defining one or more bottom orifices around the bottom opening with the one or more bottom orifices communicated to the chutes; a retaining rim joined to the side wall at the top opening with the retaining rim defining a perimeter length sized to generally match a perimeter length of an opening of the collection bag and wherein the top opening has a perimeter length greater than the perimeter length of the retaining rim to thereby provide one or more top orifices communicated to the chutes between the retaining rim and the inner wall; whereby a plurality of air channels are formed by the plurality of chutes when the collection bag is disposed within the volume and the opening of the collection bag is coupled to the retaining rim with the air channels communicating air flow between the one or more top orifices and the one or more bottom orifices. 
     A method for collecting organic waste in a collection bag, the method including a) disposing the collection bag within a volume of a collection device, the collection device having a side wall enclosing the volume and defining a top opening and bottom opening wherein a plurality of vertically extending air channels are formed between the collection bag and the side wall responsive to a structure extending into the volume from the side wall interacting with the collection bag; b) supporting a bottom of the collection bag on a bottom joined to the side wall with the bottom including one or more bottom orifices communicated to the vertically extending air channels; and c) retaining an opening of the collection bag in an open configuration at the top opening with one or more top orifices formed around the opening and communicated to the vertically extending air channels. 
     Embodiments of the present invention enhance air circulation around the collection bag and thereby reduce anaerobic composition of the organic waste. As such, this device is not designed as a composter but as a collection apparatus and method to gather and store organic waste for later composting. This reduces the generation of the compost fluids and odors and reduces attractiveness to pests. Further, the orifices at the top and bottom enable the collection device to appear as a more conventional collection device and not appear out-of-place in a household environment. Thus the device promotes its adoption and use. 
     Other features, benefits, and advantages of the present invention will be apparent upon a review of the present disclosure, including the specification, drawings, and claims.

     DETAILED DESCRIPTION OF THE INVENTION 
     Embodiments of the present invention provide a compost collector that permits aesthetic accumulation and storage of household organic waste that is more sanitary, less messy, and less odiferous. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements 
     Various modifications to the preferred embodiment and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiment shown but is to be accorded the widest scope consistent with the principles and features described herein. 
       FIG. 1  illustrates a perspective view of a countertop compost collector  100 .  FIG. 2  illustrates a front view thereof;  FIG. 3  illustrates a back view thereof;  FIG. 4  illustrates a right-hand view thereof;  FIG. 5  illustrates a top view thereof;  FIG. 6  illustrates a bottom view thereof; and  FIG. 7  illustrates a left-hand view thereof. 
       FIG. 8  illustrates an expanded disassembled plan layout of components of countertop compost collector  100 . Collector  100  includes a sidewall  805  enclosing a volume and having a top opening and a bottom opening. Provided on an inside surface of sidewall  805  are a plurality of support ribs  810  that extend substantially vertically along a length of sidewall  805  (from near the bottom opening to near the top opening). Between adjacent support ribs  810  a chute  815  is formed, that extends the length of the support ribs. 
     A bottom  820  joins to the bottom opening and includes an arrangement of support structures  825  that define (by forming spaces or the like), when bottom  805  is joined to sidewall  805 , one or more bottom orifices communicated to chutes  815 . 
     A retaining rim  830  joins to the top opening in such a way that it defines, when rim  830  is joined to sidewall  805 , one or more top orifices communicated to chutes  815 . Rim  830  has a perimeter sized to generally match a perimeter of a collection bag placed inside the volume defined by sidewall  805 . The top opening has a perimeter larger than the perimeter of retaining rim  830  and this difference in length provides the one or more top orifices. 
     A lid  835  is, in the preferred embodiment, sized to match the perimeter of retaining rim  830  rather than the perimeter of the top opening which keeps the top orifice(s) clear of obstruction. The preferred embodiment includes an optional retaining bail  840  that clamps to rim  830  (with a mouth of the collection bag therebetween) to retain the collection bag upright within the volume and to maintain the mouth open and accessible when lid  835  is open. 
       FIG. 9  illustrates an assembled plan view of the countertop compost collector  100  including a retained collection bag  905  and one or more top orifices  910  and one or more bottom orifices  915 . (Note in  FIG. 9 , bail  840  is shown in two different configurations (though collector  100  includes a single bail  840  in its preferred implementation). This is done to show the interior and open/close mode for bail  840  as an aid to the reader.) 
     Placing bag  905  within sidewall  805  with the mouth of bag  905  either “stretched” over rim  830  or otherwise overlapping and clamping bail  840  to rim  830  to capture the mouth of bag  905 , maintains the mouth open and retains bag  905  upright (in the preferred embodiment bag  905  “hangs” from rim  830 ). Bag  905  cooperates with chutes  815  to form air channels extending between top orifice(s)  910  and bottom orifice(s)  915 . Through this expedient, air actively circulates around contents of bag  905  and inhibits any anaerobic decomposition. 
     In the preferred embodiment, bag  905  is a biodegradable/compostable bag, permitting bag  905 , when filled, to be removed from collector  100 , closed, and added to a compost pile or put into a “green” recycling process. Most preferably, bag  905  includes microperforations to enhance aerobic processes and to discourage anaerobic decomposition. For example, BioBag® (made from Mater-Bi that is produced by Novamont, an Italian research company) available from BioGroup USA of Palm Harbor, Fla., is a preferred collection bag for use with collector  100 . 
     The components of collector  100  are preferably made from environmentally friendly resources, such as a blend of melamine and bamboo waste. The contained volume is preferably about 2.5 gallons. Of course, other materials and volumes are within the scope of the present invention. By providing the top and bottom orifices as described, collector  100  appears to be a sealed container and may be decorated and designed to fit into the household environment without appearing to be a “compost” related device which may detract from its acceptance by some otherwise would-be users. The air channels, provided from fully or partially closed chutes, promote all-around air flow. 
     As noted herein, the system and process are most preferably implemented in cooperation between a collection bag and a collection device that provides air circulation channels when the bag is used in the device, with orifices at a top and a bottom opening communicating to each other through these channels to enhance air flow (and reduce anaerobic decomposition) of materials placed inside the bag. 
     The system and methods above has been described in general terms as an aid to understanding details of preferred embodiments of the present invention. Other preferred embodiments of the present include the described application for organic waste collection.
