Abstract

A sheet product dispenser for dispensing sheet product from a roll of sheet product is provided. The sheet product dispenser includes a housing defining an interior space configured to receive the roll of sheet product therein. The housing includes a nozzle configured to allow the sheet product to be dispensed therethrough and out of the interior space of the housing. The nozzle includes a first orifice disposed at or near an outer end of the nozzle, a second orifice disposed at or near an inner end of the nozzle, and a cavity disposed between the first orifice and the second orifice. The first orifice, the second orifice, and the cavity are configured to allow the sheet product to pass therethrough. The first orifice has a first cross-sectional area, the second orifice has a second cross-sectional area, and the cavity has a third cross-sectional area, wherein the third cross-sectional area is greater than the first cross-sectional area and greater than the second cross sectional area.

First claim

We claim:

1 . A sheet product dispenser for dispensing sheet product from a roll of sheet product, the sheet product dispenser comprising:
a housing defining an interior space configured to receive the roll of sheet product therein, the housing comprising: a nozzle configured to allow the sheet product to be dispensed therethrough and out of the interior space of the housing, the nozzle comprising:
a first orifice disposed at or near an outer end of the nozzle and configured to allow the sheet product to pass therethrough, the first orifice having a first cross-sectional area;
a second orifice disposed at or near an inner end of the nozzle and configured to allow the sheet product to pass therethrough, the second orifice having a second cross-sectional area; and
a cavity disposed between the first orifice and the second orifice and configured to allow the sheet product to pass therethrough, the cavity having a third cross-sectional area;
wherein the third cross-sectional area is greater than the first cross-sectional area and greater than the second cross sectional area.

2 . The sheet product dispenser of claim 1 , wherein the second cross-sectional area is greater than the first cross-sectional area.

3 . The sheet product dispenser of claim 1 , wherein the first orifice, the second orifice, and the cavity are coaxial with a central axis of the nozzle.

4 . The sheet product dispenser of claim 1 , wherein the first orifice has a circular cross-sectional shape, wherein the second orifice has a circular cross-sectional shape, and wherein the cavity has a circular cross-sectional shape.

5 . The sheet product dispenser of claim 1 , wherein the first orifice has a circular cross-sectional shape and a diameter of between 6 millimeters and 8 millimeters.

6 . The sheet product dispenser of claim 1 , wherein the first orifice and the second orifice have different cross-sectional shapes.

7 . The sheet product dispenser of claim 1 , wherein the first orifice has a cylindrical shape, wherein the second orifice has a cylindrical shape, and wherein the cavity has a cylindrical shape.

8 . The sheet product dispenser of claim 1 , wherein the second orifice has a tapered shape.

9 . The sheet product dispenser of claim 1 , wherein the cavity has a tapered shape.

10 . The sheet product dispenser of claim 1 , wherein the second orifice comprises a plurality of barbs extending inward toward a central axis of the nozzle.

11 . The sheet product dispenser of claim 1 , wherein the housing comprises a cover and a nozzle cap attached to the cover.

12 . The sheet product dispenser of claim 11 , wherein the first orifice is defined in the nozzle cap, and wherein the second orifice and the cavity are defined in the cover.

13 . The sheet product dispenser of claim 11 , wherein the first orifice and the cavity are defined in the nozzle cap, and wherein the second orifice is defined in the cover.

14 . The sheet product dispenser of claim 11 , wherein the first orifice, the second orifice, and the cavity are defined in the nozzle cap.

15 . The sheet product dispenser of claim 11 , wherein the nozzle cap is removably attached to the cover.

16 . The sheet product dispenser of claim 1 , wherein the housing comprises a cover, and wherein first orifice, the second orifice, and the cavity are defined in the cover.

17 . The sheet product dispenser of claim 1 , further comprising a roll of sheet product disposed within the interior space of the housing.

18 . The sheet product dispenser of claim 17 , wherein the sheet product comprises bath tissue.

19 . The sheet product dispenser of claim 17 , wherein the sheet product comprises a plurality of lines of perforations defining a plurality of sheets.

20 . The sheet product dispenser of claim 19 , wherein each sheet has a rectangular shape having a transverse width and a longitudinal length, wherein the transverse width is between 125 millimeters and 180 millimeters, and wherein a ratio of the transverse width to the longitudinal length is between 0.45 and 1.

21 . The sheet product dispenser of claim 19 , wherein the first orifice is configured to provide a first resistance to dispensing of the sheet product through the nozzle, and wherein the first resistance is sufficient to tear a leading line of perforations of the sheet product while leaving a predetermined length of a tail of the sheet product extending from the nozzle.

22 . The sheet product dispenser of claim 19 , wherein the first orifice is configured to provide a first resistance to dispensing of the sheet product through the nozzle, wherein the second orifice is configured to provide a second resistance to dispensing of the sheet product through the nozzle, and wherein a sum of the first resistance and the second resistance is sufficient to tear a leading line of perforations of the sheet product while leaving a predetermined length of a tail of the sheet product extending from the nozzle.

23 . A nozzle for dispensing sheet product from a roll of sheet product, the nozzle comprising:
a first orifice disposed at or near an outer end of the nozzle and configured to allow the sheet product to pass therethrough, the first orifice having a first cross-sectional area; a second orifice disposed at or near an inner end of the nozzle and configured to allow the sheet product to pass therethrough, the second orifice having a second cross-sectional area; and a cavity disposed between the first orifice and the second orifice and configured to allow the sheet product to pass therethrough, the cavity having a third cross-sectional area; wherein the third cross-sectional area is greater than the first cross-sectional area and greater than the second cross sectional area.

24 . The nozzle of claim 23 , wherein the second cross-sectional area is greater than the first cross-sectional area.

25 . The nozzle of claim 23 , wherein the first orifice, the second orifice, and the cavity are coaxial with a central axis of the nozzle.
