The rolls are held in place within the interior space of the housing by a pair of spindle holders. The housing front cover has an opening and a slidable door disposed therein to provide access to the rolls. A restricting member is movably coupled to the housing interior and biased to move in a direct towards an outmost winding of a roll. As the roll is dispensed, the restricting member moves out of the pathway of the door, eventually allowing a user to slide the door across the opening so that a second roll may be accessed. ## Claims ### Claim 1 A dispenser for dispensing rolls of sheet material, comprising: a housing having an interior space; a first pair of spindle holders disposed in a first portion of the interior space and configured to removably receive a first spindle; a second pair of spindle holders disposed in a second portion of the interior space and configured to removably receive a second spindle; wherein the first pair of spindle holders defines a first axis about which the first spindle rotates, and the second pair of spindle holders defines a second axis about which the second spindle rotates; an opening sized and dimensioned to provide access to the interior space; a sliding door disposed in the opening of the housing that slides across the opening between a first position and a second position; wherein, in the first position, the door allows access to the first portion of the interior space and limits access to the second portion of the interior space; wherein, in the second position, the door limits access to the first portion of the interior space and allows access to the second portion of the interior space; and a first restricting member disposed in the interior space of the housing and biased to rotate about a third axis such that (i) a first end of the first restricting member rotates towards the first axis and (ii) a second end of the first restricting member rotates away from the first axis and out of a pathway of the sliding door, wherein the third axis is parallel to the first axis. ### Claim 2 (depends on 1) The dispenser of claim 1, wherein the first and second pairs of spindle holders are configured to simultaneously receive the first and second spindles, respectively. ### Claim 3 (depends on 1) The dispenser of claim 1, wherein the first spindle is of a fixed length. ### Claim 4 (depends on 1) The dispenser of claim 1, wherein the first spindle is of a variable length. ### Claim 5 (depends on 1) The dispenser of claim 1, further comprising a second restricting member disposed in the interior space of the housing and biased to rotate in a second direction such that (i) a first end of the second restricting member moves towards the second axis and (ii) a second end of the second restricting member moves away from the second axis and into the pathway of the sliding door. ### Claim 6 (depends on 1) The dispenser of claim 1, the sliding door slides along a track that is disposed on a border of the opening. ### Claim 7 (depends on 1) The dispenser of claim 1, wherein the first end of the first restricting member rests on an outmost winding of a first roll when the first roll is stored in the first portion of the interior space of the housing. ### Claim 8 (depends on 7) The dispenser of claim 7, wherein the first end of the first restricting member rotates towards the outmost winding of the first roll as the first roll of sheet material is depleted. ### Claim 9 (depends on 8) The dispenser of claim 8, wherein the second end of the first restricting member rotates out of the pathway of the door as the first roll of sheet material is depleted. ### Claim 10 (depends on 9) The dispenser of claim 9, wherein the first restricting member is sized, dimensioned, and positioned, such that the second end rotates completely out of the pathway of the door when the first roll of sheet material is more than 95% depleted. ### Claim 11 (depends on 1) The dispenser of claim 1, wherein the housing further comprises a front cover rotatably coupled with a rear member. ### Claim 12 (depends on 11) The dispenser of claim 11, wherein the opening and the sliding door are disposed on the front cover. ### Claim 13 (depends on 1) The dispenser of claim 1, wherein the first portion and second portion of the interior space are separated by a partition. ### Claim 14 A dispenser for dispensing rolls of sheet material, comprising: a housing having an interior space; a first pair of spindle holders disposed in a first portion of the interior space and configured to removably receive a first spindle; a second pair of spindle holders disposed in a second portion of the interior space and configured to removably receive a second spindle; wherein the first pair of spindle holders defines a first axis about which the first spindle rotates, and the second pair of spindle holders defines a second axis about which the second spindle rotates; an opening sized and dimensioned to provide access to the interior space; a sliding door disposed in the opening of the housing that slides across the opening between a first position and a second position; wherein, in the first position, the door allows access to the first portion of the interior space and limits access to the second portion of the interior space; wherein, in the second position, the door limits access to the first portion of the interior space and allows access to the second portion of the interior space; a first restricting member disposed in the interior space of the housing and biased to rotate about a third axis such that (i) a first end of the first restricting member rotates towards the first axis and (ii) a second end of the first restricting member rotates away from the first axis and out of a pathway of the sliding door; and wherein the first end of the first restricting member rests on an outmost winding of a first roll when the first roll is stored in the first portion of the interior space of the housing. ### Claim 15 (depends on 14) The dispenser of claim 14, wherein the first end of the first restricting member rotates towards the outmost winding of the first roll as the first roll of sheet material is depleted. ### Claim 16 (depends on 15) The dispenser of claim 15, wherein the second end of the first restricting member rotates out of the pathway of the door as the first roll of sheet material is depleted. ### Claim 17 (depends on 16) The dispenser of claim 16, wherein the first restricting member is sized, dimensioned, and positioned, such that the second end rotates completely out of the pathway of the door when the first roll of sheet material is more than 95% depleted. ### Claim 18 (depends on 14) The dispenser of claim 14, wherein the first end of the first restricting member rotates using a spring-based mechanism. ### Claim 19 (depends on 14) The dispenser of claim 14, wherein the door comprises a protrusion. ### Claim 20 (depends on 19) The dispenser of claim 19, wherein the protrusion and the second end of the first restriction member are sized and dimensioned to interfere with one another until a predetermined diameter of a roll paper product is reached.
