Abstract

A system provides a shaped access path to a bag within a receptacle or can. The system comprises a funnel-providing system of a neck portion and a funnel portion. The funnel-providing portion comprises a flexible material that forms a leading edge of the funnel portion that curves back onto itself to form a funnel having a wide leading edge and a narrower base of the funnel portion. The narrower base of the funnel portion is connected to the neck portion. A gripping element extends over at least a length of the neck portion, the gripping portion capable of gripping an element (such as the end of a plastic bag) placed between the gripping element and the neck portion.

Claims (32)

1. A system for providing a shaped access path to a bag within a receptacle comprising:

a funnel-providing system comprising a neck portion and a funnel portion;

the funnel-providing portion comprising a flexible material that forms a leading edge of the funnel portion that curves back onto itself to form a funnel having a wide leading edge and a narrower base of the funnel portion;

the narrower base of the funnel portion connected to the neck portion having stings attached at edges of the narrower base to enable the edges to be shaped towards each other;

a gripping element that extends over at least a length of the neck portion, the gripping portion capable of gripping an element placed between the gripping element and the neck portion.

2. The system of claim 1 wherein the leading edge of the funnel-providing portion forms a straight edge that is not curved when the funnel is shaped.

3. The system of claim 1 wherein the neck portion is adjustable to provide different stable circumferences of the neck portion for insertion into receptacles of varying sizes.

4. The system of claim 3 wherein the neck portion is adjustable to provide different levels of tension against inside surfaces of the receptacle.

5. The system of claim 1 further comprising at least one extension that can be inserted into round to secure the system against movement.

6. The system of claim 1 secured to a receptacle comprising a can with at least a 1 cubic meter volume, the can having a polymeric bag within the volume of the can and ends of the bag extending over edges of the opening of the can, the gripping elements gripping the ends of the bag to prevent slippage of the bag within the can.

7. The system of claim 2 secured to a receptacle comprising can with at least a 1 cubic meter volume, the can having a polymeric bag within the volume of the can and ends of the bag extending over edges of the opening of the can, the gripping elements gripping the ends of the bag to prevent slippage of the bag within the can.

8. The system of claim 3 secured to a receptacle comprising a can with at least a 1 cubic meter volume, the can having a polymeric bag within the volume of the can and ends of the bag extending over edges of the opening of the can, the gripping elements gripping the ends of the bag to prevent slippage of the bag within the can.

9. The system of claim 4 secured to a receptacle comprising a can with at least a 1 cubic meter volume, the can having a polymeric bag within the volume of the can and ends of the bag extending over edges of the opening of the can, the gripping elements gripping the ends of the bag to prevent slippage of the bag within the can.

10. The system of claim 5 secured to a receptacle comprising a can with at least a 1 cubic meter volume, the can having a polymeric bag within the volume of the can and ends of the bag extending over edges of the opening of the can, the gripping elements gripping the ends of the bag to prevent slippage of the bag within the can.

11. The system of claim 1 wherein the string passes through holes or handles on the edges to allow pulling on the string to shape the funnel portion.

12. The system of claim 10 lying horizontally along ground, with the at least one extension penetrating the ground to restrict movement of the can when force is applied to the system.

13. The system of claim 11 secured to a receptacle comprising a can with at least a 1 cubic meter volume, the can having a polymeric bag within the volume of the can and ends of the bag extending over edges of the opening of the can, the gripping elements gripping the ends of the bag to prevent slippage of the bag within the can.

14. The system of claim 13 further comprising at least one extension that can be inserted into ground to secure the system against movement.

15. A system for providing a shaped access path to a bag within a receptacle comprising:

a funnel-providing system comprising a neck portion and a funnel portion;

the funnel-providing portion comprising a flexible material that forms a leading edge of the funnel portion that curves back onto itself to form a funnel having a wide leading edge and a narrower base of the funnel portion;

the narrower base of the funnel portion connected to the neck portion;

a gripping element that extends over at least a length of the neck portion, the gripping portion capable of gripping an element placed between the gripping element and the neck portion, further comprising at least one extension that can be inserted into ground to secure the system against movement wherein the at least one extension comprises stakes attached to the system.

16. The system of claim 15 secured to a receptacle comprising a can with at least a 1 cubic meter volume, the can having a polymeric bag within the volume of the can and ends of the bag extending over edges of the opening of the can, the gripping elements gripping the ends of the bag to prevent slippage of the bag within the can.

17. The system of claim 16 lying horizontally along ground, with the at least one extension penetrating the ground to restrict movement of the can when force is applied to the system.

18. A system for providing a shaped access path to a bag within a receptacle comprising:

a funnel-providing system comprising a neck portion and a funnel portion;

the funnel-providing portion comprising a flexible material that forms a leading edge of the funnel portion that curves back onto itself to form a funnel having a wide leading edge and a narrower base of the funnel portion;

the narrower base of the funnel portion connected to the neck portion;

a gripping element that extends over at least a length of the neck portion, the gripping portion capable of gripping an element placed between the gripping element and the neck portion, further comprising at least one extension that can be inserted into ground to secure the system against movement wherein the at least one extension comprises stakes that can be affixed to the receptacle separately from the system.

19. The system of claim 18 secured to a receptacle comprising a can with at least a 1 cubic meter volume, the can having a polymeric bag within the volume of the can and ends of the bag extending over edges of the opening of the can, the gripping elements gripping the ends of the bag to prevent slippage of the bag within the can.

20. The system of claim 19 lying horizontally along ground, with the at least one extension penetrating the ground to restrict movement of the can when force is applied to the system.
