Abstract

A dispensing nozzle comprising a plate overlying a bore defined through a countertop for the passage of bags therethrough from a subjacent storage position. The plate defines an elongate zig-zag slot for the restrictive movement of bags therethrough upon a manual pulling of a leading bag. Each manually pulled leading bag is automatically severed from a following bag secured thereto along a line of severance by slot-developed resistance. Introduction of the forwardmost bag of a bag package is facilitated by an enlarged opening laterally of one side of the slot and communicated with the slot through a relatively narrower neck portion. The nozzle may include a tubular sleeve receivable in the countertop bore, with the plate secured to or integrally formed with the sleeve across one end thereof.

Claims

1. In a system for individually severing and dispensing plastic bags from a package of bags sequentially joined along severance lines, a counter including a countertop having a product-receiving upper surface, bag storage means below said countertop for supporting a package of bags for the sequential drawing of bags therefrom, a bore through said countertop, a bag dispensing nozzle including a plate portion mounted on said countertop in alignment with said bore, said nozzle further defining a bag-passing aperture in said plate portion and including opposed spaced edges defining an elongated dispensing slot with means resisting the free movement of bags therethrough, said means resisting the free movement of bags comprising alternating projections and recesses along said edges defining a zigzag configuration, said bag passing aperture further including a bag supply introducing opening extending through said plate laterally to one side of said slot and communicating with said slot through an adjacent slot edge, said opening being of greater width than said slot and including a generally circular portion remote from said slot and a radial extension interconnecting said circular portion and said slot whereby the first bag from said bag supply is initially introduced through said bag supply opening and moved to said bag dispensing slot by withdrawal of the initial bag from the supply and subsequent bags are dispensed through said dispensing slot.

2. In the system of claim 1, said nozzle further including a tubular sleeve defining a central passage, said sleeve being receivable within said countertop bore, said passage having an upper end portion including a countersunk seat defined therein and receiving said plate.

3. In the system of claim 2, said sleeve including an upper end portion with an outwardly projecting integral flange peripherally thereabout, said flange seating on said countertop surface upon reception of said sleeve in the countertop bore.

4. In the system of claim 1, said nozzle including a tubular sleeve defining a central passage, said sleeve being receivable in said countertop bore, said plate overlying said passage and being integrally molded with said sleeve.

5. In the system of claim 4, a flange coplanar with and integral with said plate, said flange extending outwards of said sleeve peripherally thereabout.

6. In the system of claim 1, multiple spaced bores through said countertop with an individual nozzle mounted on said countertop in alignment with each bore for accommodating multiple packages of bags, on associated with each nozzle.

7. In the system of claim 6, each nozzle comprising a plate with the bag-passing aperture defined therethrough, said aperture including opposed spaced generally parallel edges defining an elongate slot with means resisting the free movement of bags therethrough.

8. The dispensing nozzle of claim 1 including a tubular sleeve with opposed ends, a central passage defined through said sleeve between said ends, said plate overlying said passage at one end of said sleeve.

9. The dispensing nozzle of claim 8 including a countersunk seat about said passage receiving said plate.

10. The dispensing nozzle of claim 8 including an integral outwardly enlarged flange on said sleeve generally coplanar with said plate.

11. The dispensing nozzle of claim 8 wherein said plate is integrally molded with said sleeve and defines a one-piece unit therewith.

12. The dispensing nozzle of claim 11 including an integral outwardly enlarged flange on said sleeve generally coplanar with said plate.

13. The dispensing nozzle of claim 12 including friction retaining means on and peripherally about said sleeve.

14. The dispensing nozzle of claim 13 wherein said friction retaining means comprises a peripheral groove in said sleeve and an O-ring mounted in said groove and projecting peripherally outward of said sleeve.

15. The dispensing nozzle of claim 12 wherein said flange includes a feathered outer peripheral edge.

16. The dispensing nozzle of claim 8 wherein said plate is defined by two separate segments with the slot formed therebetween.

17. For use in a countertop dispensing system as defined by claim 1 for individually severing and dispensing bags from a package of bags sequentially joined along severance lines, wherein said nozzle comprises a one-piece dispensing nozzle comprising a tubular sleeve with opposed ends, said sleeve defining a central passage between said ends, and plate wherein said is integral with said sleeve transversely over one end thereof, and an integral flange generally coplanar with said plate, said flange projecting radially outward of said sleeve peripherally thereabout, said plate including said bag-passing aperture therein for the selective drawing of bags therethrough.

18. The dispensing nozzle of claim 17 wherein said bag-passing aperture includes opposed generally parallel spaced edges defining said elongate slot with means resisting free movement of bags therethrough.
