Waste container includes a base defining a waste-receiving compartment, and an insert supported on the base and adapted to engage a peripheral edge of a bag that extends into the compartment while maintaining an opening of the bag unobstructed. The insert has at least one bag-engagement edge and possibly up to four such edges. A movable closure component has a first engagement position in which the closure component engages with the insert to press the bag when present against the at least one bag-engagement edge of the insert, and a second non-engagement position in which the closure component is separated from the at least one bag-engagement edge of the insert. A lid is preferably attached to the base and movable between a first, closed position covering the opening of the bag and a second, open position in which it does not obstruct the opening of the bag.

1. A waste container for use with a bag, comprising: a base defining a waste-receiving compartment;an insert supported on said base, said insert including an annular disc having an inner bag-engagement edge region defining an aperture and at least one bag-engagement edge, an outer edge region defining an exposed outer edge of said annular disc facing away from said aperture, and a retainer arranged on said annular disc at said outer edge region, said at least one bag engagement edge and said retainer being elevated in a common direction from said annular disc, said retainer being situated between said exposed outer edge of said annular disc and said at least one bag-engagement edge;a closure component including an annular part and a tab situated outward of a radially outer edge of said annular part and extending beyond said annular part in a direction radially outward from said annular part, said closure component having a first engagement position in which said tab of said closure component engages with said retainer of said insert and the bag when present is pressed by said annular part of said closure component against said at least one bag-engagement edge of said annular disc of said insert to thereby cause said closure component to fix the bag to said insert and prevent movement of the bag relative to said insert, and a second non-engagement position in which said tab of said closure component is not engaged with said retainer of said insert and the bag is not fixed to said insert to enable removal of the bag from the waste disposal device and placement of a new bag into the waste disposal device, said closure component being movable between the first and second positions; anda lid attached to said base and that is movable between a first, closed position covering the opening of the bag when fixed by said closure component to said insert and a second, open position in which it does not obstruct the opening of the bag when fixed by said closure component to said insert. 2. The waste container of claim 1, wherein said closure component is attached to said insert. 3. The waste container of claim 1, wherein said inner edge region of said insert further includes an inner wall, a ledge extending radially inward from an upper edge of said inner wall and an annular wall extending downward from an inner edge of said ledge, said annular part of said closure component having a U-shaped cross-section defining a channel having an opening facing said insert, said closure component being positioned in the first position such that said inner wall, said ledge and said annular wall are received in said channel around an entire periphery of said insert and said at least one bag-engagement surface thereby constituting three bag-engagement surfaces. 4. The waste container of claim 3, wherein said closure component is attached to said insert. 5. The waste container of claim 1, wherein said retainer is flexible and includes a vertical portion, a lip proximate a top of said vertical portion and under which said tab is received, a flange proximate the top of said vertical portion opposite said lip and an angled surface arranged above said lip to facilitate placement of said tab under said lip as said retainer flexes said tab being configured to be urged into engagement with said retainer against the flexure of said retainer and said retainer being configured to require flexure thereof to enable release of said tab from engagement with said retainer. 6. The waste container of claim 3, wherein said tab projects outward from said annular part at a location opposite an attachment point at which said closure component is attached to said insert. 7. A waste container for use with a bag, comprising: a base defining a waste-receiving compartment;a bag support on said base and that includes an annular disc, an annular rim arranged on said annular disc and defining an aperture, and a retainer arranged on said annular disc, said rim being adapted to engage a peripheral edge of the bag around an opening of the bag while maintaining the opening of the bag unobstructed with the bag extending into said compartment, said rim and said retainer being elevated in a common direction from said annular disc, said retainer being situated between an outer radial edge of said annular disc facing away from said aperture and an outer edge of said rim facing away from said aperture; anda closure component including an annular part and a tab situated outward of a radially outer edge of said annular part and extending beyond said annular part in a direction radially outward from said annular part, said closure component being configured to selectively cooperate with said rim when said tab is engaged with said retainer to press the bag when present against said rim when said closure component cooperates with said rim to thereby cause said closure component to fix the bag to said bag support only when said closure component cooperates with said rim and said tab is engaged with said retainer and prevent movement of the bag relative to said insert, an upper region of the bag being positionable around said rim and the bag being separable from said rim when said closure component does not cooperate with said rim and said tab is not engaged with said retainer to enable removal of the bag from the waste disposal device and placement of a new bag into the waste disposal device, said closure component being movable between a position cooperating with said rim and a position not cooperating with said rim. 8. The waste container of claim 7, wherein said retainer is flexible and includes a vertical portion, a lip proximate a top of said vertical portion and under which said tab is received, a flange proximate the top of said vertical portion opposite said lip and an angled surface arranged above said lip to facilitate placement of said tab under said lip as said retainer flexes said tab being configured to be urged into engagement with said retainer against the flexure of said retainer and said retainer being configured to require flexure thereof to enable release of said tab from engagement with said retainer. 9. The waste container of claim 7, further comprising a lid attached to said base and that is movable between a first, closed position covering the opening of the bag when fixed by said closure component to said bag support and a second, open position in which it does not obstruct the opening of the bag when fixed by said closure component to said bag support.
