Sheet product dispensers and related methods for reducing sheet product usage

A resistance mechanism for a sheet product dispenser, the resistance mechanism comprising:

• an arm configured to frictionally engage a surface of a roll of sheet product disposed in the sheet product dispenser;
• and
• a spring attached to the arm and configured to bias the arm into engagement with the roll of sheet product, such that the resistance mechanism provides a pull force resistance opposing a pull force applied to a tail portion of the roll of sheet product;
• wherein the pull force resistance decreases as an outer diameter of the roll of sheet product decreases.

A sheet product dispenser comprising:

• a first roll of sheet product rotatably supported by the sheet product dispenser;
• a first resistance mechanism in contact with a first surface of the first roll of sheet product, the first resistance mechanism comprising:
• an arm configured to frictionally engage the first surface of the first roll of sheet product;
• and
• a spring attached to the arm and configured to bias the arm into engagement with the first surface, such that the resistance mechanism provides a pull force resistance opposing a pull force applied to a tail portion of the roll of sheet product;
• wherein the sheet product dispenser is configured to dispense a length of sheet product from the roll of sheet product.
