Abstract
A sheet product dispenser includes a housing to partially enclose a roll of sheet product, at least one end-opening at a longitudinal end of the housing to load said roll within the housing, and a longitudinal slit along a length of the housing to allow a leading edge of said sheet product to be unrolled therethrough defined by an upper and lower lip of the housing. The upper lip can flex to contact the lower lip to hold the sheet product in place during a cutting operation. The dispenser may further include a deforming projection disposed on a portion of the lower lip to deform the sheet product during a cutting operation to prevent roll-back of the sheet product.
Claims38
A sheet product dispenser, comprising:
- a housing to partially enclose a roll of sheet product, the housing comprising:
- at least one end-opening defined at a longitudinal end of the housing to load said roll within the housing, the at least one end-opening having a diameter at least larger than a diameter of said roll,
- a longitudinal slit along a length of the housing to allow a leading edge of said sheet product to be unrolled through said longitudinal slit, a length of the longitudinal slit corresponding to a width of the sheet product,
- an upper lip defining an upper portion of the longitudinal slit,
- a lower lip defining a lower portion of the longitudinal slit and projecting outward from the longitudinal slit to support the leading edge of the sheet product,
- a cutting edge disposed at an end of the lower lip to cut a section of unrolled sheet product,
- a deforming projection disposed on a portion of the lower lip projecting outward from the longitudinal slit to deform the sheet product during a cutting operation to prevent roll-back of the sheet product,
- wherein a height of the longitudinal slit corresponds to a gap between the lower and upper lips, and a height of the deforming projection is greater than the height of the gap in an area of the longitudinal slit corresponding to the deforming projection;
- wherein the gap defining the longitudinal slit is smaller at a center portion of the longitudinal slit corresponding to the deforming projection;
- and
- at least one end plug to cover the at least one end-opening and to support the roll of sheet material within the housing.
