A thin-ply roll holder, for example, a paper towel holder facilitates tearing of paper towels from a continuous roll supported on the holder, and prevents excessive unraveling of the roll. A pressure bar pivots at a hinge on the base, and is spring biased towards the pole that supports the roll, such that leverage of the bias about a hinge increases as the pressure bar pivots towards the pole, but the bias decreases at a lower rate than the increase in the leverage. At the distal free end of the pole, a retaining tab is pivoted to flip from a first orientation in which the hollow core of the paper towel is permitted to be received by the pole, to a second orientation in which the paper towel is not permitted to be removed from the pole. The pole is structured as a frame structure comprising rod-shaped segments.

The invention claimed is: 1. A holder for a thin-ply roll, comprising: a base; a pole having one end attached to the base, and a distal end extending from the base; and a pressure bar pivotally attached to the base at a hinge, and is biased towards the pole, wherein the pressure bar presses against
The invention claimed is: 1. A holder for a thin-ply roll, comprising: a base; a pole having one end attached to the base, and a distal end extending from the base; and a pressure bar pivotally attached to the base at a hinge, and is biased towards the pole, wherein the pressure bar presses against a thin-ply roll placed on the base, and wherein the bias is configured to increase as the pressure bar pivots towards the pole. 2. The holder as in claim 1, wherein the pressure bar is pivotally attached to a rim of the base. 3. The holder as in claim 2, wherein the pressure bar comprises an arm supporting a pad that has a contact surface facing the pole. 4. The holder as in claim 3, wherein the arm pivotally supports the pad. 5. The holder as in claim 1, wherein the pressure bar is biased by a spring bias in an axial direction towards the pole, and wherein the spring bias is applied to a point on the pressure bar such that leverage of the spring bias about the hinge increases as the pressure bar pivots towards the pole. 6. The holder as in claim 5, wherein the spring bias is a spring tension bias, and wherein the spring tension decreases at a lower rate than the increase in the leverage. 7. The holder as in claim 1, wherein the thin-ply roll comprises a paper towel roll. 8. The bolder as in claim 1, further comprising a retaining tab provided near the distal end of the pole. 9. The holder as in claim 8, wherein the retaining tab is pivotally attached near the distal end of the pole, wherein the tab can be pivoted from a first position in which the retaining tab extends generally radial with respect to the pole, and a second position in which the retaining tab extends axially with respect to the pole. 10. The holder as in claim 9, wherein a resistance is provided to hold the retaining tab at least at the first position to resist pivoting action. 11. The holder as in claim 1, wherein the bias is configured to increase as the pressure bar pivots closer towards the pole. 12. A holder for a thin-ply roll, comprising: a base; a pole having one end attached to the base, and a distal end extending from the base; and a retaining tab provided near the distal end of the pole, wherein the retaining tab is pivotally attached near the distal end of the pole, wherein the retaining tab can be pivoted from a first position in which the retaining tab extends generally radial with respect to the pole, and a second position in which the retaining tab extends axially with respect to the pole, and wherein a resistance is provided to hold the retaining tab at least at the second position to resist pivoting action, which spring bias is overcome to pivot the retaining tab from the second position to the first position. 13. The holder as in claim 12, wherein the resistance is provided to hold the retaining tab also at the first position to resist pivoting action. 14. The holder as in claim 13, wherein the resistance is provided by a spring bias. 15. The holder as in claim 14, wherein the spring bias is a compressive spring bias. 16. The holder as in claim 12, further comprising a pressure bar pivotally attached to the base, and is biased towards the pole, wherein the pressure bar presses against a thin-ply roll placed on the base. 17. The holder as in claim 16, wherein the pressure bar is pivotally attached to a rim of the base. 18. The holder as in claim 17, wherein the pressure bar is biased by a spring bias in an axial direction towards the pole. 19. The holder as in claim 12, wherein the pole comprises a frame structure having rod-shaped segments. 20. A holder for a thin-ply roll, comprising: a base supporting the thin-ply roll; a pole having one end attached to the base, and a distal end extending from the base; a retaining tab provided near the distal end of the pole, wherein the retaining tab is positioned to block removal of the thin-ply roll, wherein the retaining tab is pivotally attached near the distal end of the pole, wherein the retaining tab can be pivoted from a first position in which the retaining tab extends generally radial with respect to the pole, and a second position in which the retaining tab extends axially with respect to the pole, and wherein a resistance is provided to hold the retaining tab at least at the second position to resist pivoting action, which spring bias is overcome to pivot the retaining tab from the second position to the first position; and a pressure bar pivotally attached to the base, and is biased towards the pole, wherein the pressure bar presses against the thin-ply roll placed on the base, and wherein the bias is configured to increase as the pressure bar pivots closer towards the pole.
