The packaging unit includes a roll of sheet products and a liquid-tight bag in which the roll is arranged. The liquid-tight bag includes a removal opening for removal of the sheet products, the removal opening being delimited by a dimensionally stable coupling ring made of a tough material. The dimensionally stable coupling ring is connected to an annular feeder encompassing a feeder opening, and the housing and the annular feeder are non-destructively and releasably connected to one another. ## Claims ### Claim 1 A sheet product dispenser comprising: a housing; a packaging unit arranged in the housing and comprising a roll of sheet products and a liquid-tight bag in which the roll is arranged, the liquid-tight bag having a removal opening for removal of the sheet products, the removal opening being delimited by a dimensionally stable coupling ring made of a tough material, the dimensionally stable coupling ring being connected to an annular feeder encompassing a feeder opening; and a closure cover comprising a flexible material, the closure cover being configured to contact the annular feeder and/or the housing in a sealing manner in a closed position and further configured to be self-closing into the closed position, wherein the housing and the annular feeder are non-destructively and releasably connected to one another. ### Claim 2 (depends on 1) The sheet product dispenser according to claim 1, wherein the housing is made of a dimensionally stable material. ### Claim 3 (depends on 1) The sheet product dispenser according to claim 1, wherein the feeder is made of a dimensionally stable material. ### Claim 4 (depends on 1) The sheet product dispenser according to claim 1, wherein at least one of the housing or the feeder the is made of a dimensionally stable, polymeric material. ### Claim 5 (depends on 1) The sheet product dispenser according to claim 1, wherein the annular feeder is connected to the housing in a force-fitting and/or a positive-locking manner. ### Claim 6 (depends on 1) The sheet product dispenser according to claim 1, wherein the feeder is arranged within the housing at a 45° angle (α) in relation to the housing being arranged in a vertically standing or a horizontally lying manner. ### Claim 7 (depends on 1) The sheet product dispenser according to claim 1, wherein the annular feeder has an essentially pot-shaped design with a bottom and a first edge, wherein the bottom includes the feeder opening and wherein the first edge is arranged on a side of the bottom facing away from the packaging unit and surrounds the bottom on an outer circumference, and in that the bottom and the first edge delimit an internal space of the annular feeder. ### Claim 8 (depends on 7) The sheet product dispenser according to claim 7, wherein the first edge is surrounded on the outer circumference by a second edge of the housing. ### Claim 9 (depends on 8) The sheet product dispenser according to claim 8, wherein the first edge and/or the second edge is contacted in a sealing manner by the closure cover in a sealed configuration. ### Claim 10 (depends on 9) The sheet product dispenser according to claim 9, wherein the closure cover is made of a thermoplastic elastomer (TPE). ### Claim 11 (depends on 9) The sheet product dispenser according to claim 9, wherein the closure cover is made of a silicon material. ### Claim 12 (depends on 7) The sheet product dispenser according to claim 7, wherein the bottom includes a recess that provides the feeder opening for a removal of the sheet products from the housing. ### Claim 13 (depends on 12) The sheet product dispenser according to claim 12, wherein the recess is formed by at least one radially outwardly tapered slot. ### Claim 14 (depends on 13) The sheet product dispenser according to claim 13, wherein the recess has an essentially star-shaped design. ### Claim 15 (depends on 1) The sheet product dispenser according to claim 1, wherein the sheet products are textile sheet products. ### Claim 16 (depends on 1) The sheet product dispenser according to claim 1, wherein the sheet products can be unrolled from a center of the roll. ### Claim 17 (depends on 1) The sheet product dispenser according to claim 1, wherein the sheet products are soaked with a cleaning and/or disinfecting liquid located in the bag. ### Claim 18 (depends on 17) The sheet product dispenser according to claim 17, wherein the bag is made of a polymeric material. ### Claim 19 (depends on 1) The sheet product dispenser according to claim 1, wherein the coupling ring is made of a dimensionally stable material. ### Claim 20 (depends on 19) The sheet product dispenser according to claim 19, wherein the coupling ring is made of a polymeric material. ### Claim 21 (depends on 1) The sheet product dispenser according to claim 1, wherein the annular feeder and the coupling ring are non-destructively and releasably connected to one another in a force-fitting and/or positive-locking manner. ### Claim 22 (depends on 1) The sheet product dispenser according to claim 1, wherein the feeder opening is smaller than a diameter of the roll. ### Claim 23 A packaging unit for a sheet product dispenser, comprising a roll of sheet products, which can be detached from the roll, and a liquid-tight bag in which the roll is arranged, wherein the bag has a removal opening for removal of the sheet products, and wherein the removal opening is delimited by a dimensionally stable coupling ring made of a tough material that is configured to be connected to an annular feeder of a sheet product dispenser, wherein a first sheet product, which can be detached from the roll, is connected to a removal lug. ### Claim 24 (depends on 23) The packaging unit according to claim 23, wherein the removal opening is sealed in an airtight and liquid-tight manner by a tearaway closure seal. ### Claim 25 (depends on 24) The packaging unit according to claim 24, wherein the closure seal is surrounded by a predetermined breaking point. ### Claim 26 (depends on 25) The packaging unit
