Waste disposal system having a slider
A waste disposal pail having a slider that is capable of moving up and down vertically within a lid insert. The slider acts to pry open a passage of the waste bag/liner when tension is no longer applied to the neck region of the waste bag/liner. When a user begins to twist the neck region of the waste bag/liner closed, the closure of the waste bag/liner pushes the slider back up into its original position.
1 . A waste disposal pail comprising:
a bottom drum to enclose a waste liner;
a lid insert disposed on top of the bottom drum;
a slider slidingly engaged with said lid insert to slide in a vertical direction between a first position and second position, said slider has a bottom-most portion to make abutting contact with the waste liner while said slider is moving from said first position to said second position;
wherein the waste liner has a neck region that defines a passage, and when said neck region is twisted thereby applies a tension force to shut closed said passage, said slider is at said first position and wherein said bottom-most portion of the slider remains disposed above said passage;
wherein when said neck region of the waste liner is untwisted to release said tension force, said slider moves vertically downward into said second position and into said passage of the waste liner to pry and/or keep said passage open;
wherein said first position is vertically higher than said second position.
2 . The waste disposal pail as recited in claim 1 , wherein when said slider moves vertically downward into said second position, said slider is not electrically driven and is not mechanically driven to move vertically downward; wherein said slider moves vertically downward into said second position by gravity, and said the bottom-most portion of said slider abuts against the waste liner to forcibly pry open said passage thereby allowing for a lightweight waste item to drop through the passage of the waste liner.
3 . The waste disposal pail as recited in claim 1 , wherein when the slider is in said second position, and when said neck region is twisted to apply said tension force to shut closed said passage, the waste liner abuts against the bottom-most portion of the slider thereby forcing said slider to move vertically upward into said first position.
4 . The waste disposal pail as recited in claim 1 , wherein said lid insert defines an opening allowing a waste item to pass therethrough before entering said waste liner, and said slider is disposed within said opening when said slider is in said first position.
5 . The waste disposal pail as recited in claim 4 , wherein lid insert has an interior wall and a detent coupled to said interior wall of the lid insert.
6 . The waste disposal pail as recited in claim 5 , wherein said slider has a dam, said dam makes abutting contact with said detent when said slider is in said second position to stop said slider from moving further downward in a vertical direction.
7 . The waste disposal pail as recited in claim 6 , wherein the slider has a cylindrical body.
8 . The waste disposal pail as recited in claim 7 , wherein and said bottom-most portion is a circular rim.
9 . The waste disposal pail as recited in claim 8 , wherein said circular rim has a bevel or chamfer surface attached thereto.
10 . The waste disposal pail as recited in claim 9 , wherein said slider has an upper rim, and said dam is coupled to the upper rim.
11 . The waste disposal pail as recited in claim 6 , wherein said slider has at least one support, and said bottom-most portion of the slider is a ring structure coupled to said at least one support.
12 . The waste disposal pail as recited in claim 11 , wherein said slider has an upper rim, and said at least one support is coupled to said upper rim.
13 . The waste disposal pail as recited in claim 12 , wherein said dam is coupled to said upper rim.
14 . The waste disposal pail as recited in claim 6 , wherein the slider is comprised of a plurality of downwardly extending panels each having a distal end, wherein said distal end defines said bottom-most portion of said slider.
15 . The waste disposal pail as recited in claim 14 , wherein said plurality of downwardly extending panels are coupled to an upper rim, and said dam is coupled to the upper rim.
16 . The waste disposal pail as recited in claim 14 , wherein said distal end of at least one of said plurality of downwardly extending panels has an arc shape.
17 . The waste disposal pail as recited in claim 6 , wherein the slider has an upper rim and a plurality of supports coupled to said upper rim, wherein each support forms an arc.
18 . The waste disposal pail as recited in claim 17 , wherein each one of said plurality of supports is a U-shaped metal wire.
