Spindle and cover components for sheet product dispensers and dispenser systems including such components

A cover assembly for a roll of sheet product, the cover assembly comprising:

• a mounting member for securing the cover assembly to a surface;
• a pair of arms spaced for securing a spindle and a roll of sheet product therebetween;
• a cover connected to the mounting member and disposed over a space between the pair of arms,
• wherein at least one of the arms comprises (i) a bearing for receiving a mounting end of the spindle and (ii) an adjustable clamp disposed about and in contact with the bearing.

A spindle for use with a coreless sheet product roll, the spindle comprising:

• a hollow cylindrical body having a first end;
• a ring defining an interior surface wherein the interior surface comprises an inward facing ledge;
• a rod which extends partially out of the first end of the hollow cylindrical body and which comprises a radial ledge;
• and
• a spring disposed within the hollow cylindrical body and having one end in biasing contact with an end of the rod disposed within the hollow cylindrical body,
• wherein the ring is attached to the first end of the hollow cylindrical body and wherein the rod is permitted to translate within the hollow cylindrical body but cannot fall out of the first end of the hollow cylindrical body due to interference between the inward facing ledge of the ring and the radial ledge of the rod,
• wherein the hollow cylindrical body has at least two fins extending directly and outwardly therefrom, the at least two fins extending axially along a length of the hollow cylindrical body, and
• wherein the hollow cylindrical body has a second end opposed to the first end and the second end comprises an integral disk and opening which is closed off by an end cap secured to the second end of the hollow cylindrical body, the end cap comprising an end piece for mounting to a roller arm.

A spindle for use with a coreless sheet product roll, the spindle comprising:

• a hollow cylindrical body having a first end;
• a ring defining an interior surface, wherein the interior surface comprises an inward facing ledge;
• a rod which extends partially out of the first end of the hollow cylindrical body and which comprises a radial ledge;
• and
• a spring disposed within the hollow cylindrical body and having one end in biasing contact with an end of the rod disposed within the hollow cylindrical body,
• wherein the rod is permitted to translate within the hollow cylindrical body but cannot fall out of the first end of the hollow cylindrical body due to interference between the inward facing ledge of the ring and the radial ledge of the rod,
• wherein the ring has a first end and an opposed second end, the first end of the ring being attached to the first end of the hollow cylindrical body, the ring further comprising an outer surface which tapers toward the second end of the ring in a region between the inward facing ledge and the second end of the ring, and
• wherein the hollow cylindrical body comprises an internal wall which separates a first hollow space open toward the first end of the hollow cylindrical body from a second hollow space open toward an opposing second end of the hollow cylindrical body.
