How should this be named to make it clear to another developer what is going on. ( Related: http://stackoverflow.com/questions/18481599/replicating-constructors-and-new-with-object-create)

objects.js

var app = app || {};
// This is the 'model / sigular'
app.Bottle = {
    someFunc : function () {

    },
    someOtherFunc : function () {

    }
};
// This does something with all 'Bottle' hence Bottles.
app.Bottles = {
    current : [],
    create : function ( elems ) {
        for (var i = 0, len = elems.length; i < len; i++) {
            this.current.push( Object.create( app.Bottle, { 'elem' : { value: elems[ i ] } } ) );
        }
    }
};

Perhaps you could place app.Bottle into a subgroup where it is understood that it is a model i.e. app.Model.Bottle.

@mikedidthis then app.Bottles.Bottle is fine.
