  • Publication number: 20260083249
    Abstract: Arm trays for chairs, including spa chairs, and spa chairs having such arm trays. The arm trays The arm trays are mounted to, and stowable completely within, the arm of the chair. The arm trays comprise a tray panel rotatably attachable to an arm of a chair via an axle. The arm tray is configured such that an outer perimeter fits substantially entirely within a horizontal slot of the arm of the chair, and such that the first tray panel is rotatable between a stowed position in which the first tray panel is positioned substantially entirely within the horizontal slot and a deployed position in which at least a portion of the first tray panel is outside of the horizontal slot such that items can be placed on the top surface of the first tray panel.

  • Patent number: 10792218
    Abstract: A liner for use with a basin to contain a liquid features two bodies of flexible plastic which are joined at adjacent faces of the distinct plastic bodies so as to form an interface of the plastic bodies. The liner includes an air conduit adapted for guiding pressurized air substantially within the thickness of the bag from an air discharge apparatus, which generates the pressurized air, to the interior of the liner. A length of the air conduit is formed at the interface of the plastic bodies such that a circumferential wall of the length of the air conduit is defined in part by an inner face of each plastic body. The plastic body of the liner that is arranged to contact an inside face of the basin is substantially imperforate so as to isolate the liner interior, where the liquid is received, from the basin.

  • Patent number: 10195108
    Abstract: A liner for containing a soaking solution in use with a foot spa features two bodies of plastic which are joined at an interface therebetween so as to form two, individual layers. An air conduit is formed between the two layers so as to provide a passageway for pressurized air, which is supplied by an air discharge apparatus, across walls of the liner and into the soaking solution. The inner layer has openings such that the air guided through the air conduit can be released into an inside volume of the liner where the soaking solution is containable. Furthermore, the outer layer is imperforate from a location thereon at which a starting end of the air conduit is disposed to a free end of the layers so as to isolate the inside volume of the liner from the soaking basin.

  • Patent number: 9439831
    Abstract: A pedicure bowl has a bottom discharge drain opening communicating with a discharge duct and is arranged to receive a liner to ensure hygienic operation in the form of a thin flexible material applied over the inner surface to contain the liquid within the liner and to cover the drain opening. The drain opening is closed by the liner so that liquid within the container applies downward pressure on the liner at the drain opening and a sealing member is mounted in the duct downstream of the drain opening to prevent air flow so as to form a back pressure underneath the liner to prevent the downward pressure from rupturing the liner. The sealing member is operable to release the back pressure to cause the liner at the discharge opening to rupture.
