Liquid dispenser with interchangeable heads and extension poles

摘要

A liquid dispenser comprises a fluid transfer body, a reservoir with plunger, and an extender selectively attachable to the reservoir; the elongated tube shaped member has at least one wall that forms a forward rim and extends in a tubular fashion to a rearward end; the at least one wall also forms a longitudinal slot for receiving the handle of the plunger, or a lever attached to said handle; and the slot is disposed to allow the handle or lever to travel when a user pushes the handle of the plunger towards or away from the fluid transfer body end of the elongated reservoir.

主权项

1. A liquid dispenser which comprises:
a fluid transfer body having a head end for delivering fluid at a distal end, a side inlet for filling the liquid dispenser with a fluid, and a reservoir end at a proximal location for attaching the fluid transfer body with a reservoir and for communicating fluid in and out of the reservoir; the reservoir being an elongated tube shaped reservoir having a proximal end and an opposing fluid transfer body end, said elongated tube shaped reservoir in fluid communication with the fluid transfer body at the reservoir end; a plunger having a fluid contacting end connected to a handle, the fluid contacting end adapted to sealably fit inside the elongated reservoir tube and travel within the elongated reservoir tube to a.) force fluid to the fluid transfer body when the plunger travels towards the fluid transfer body end or b.) draw fluid from the fluid transfer body when the plunger travels away from the fluid transfer body end; and an extender selectively attachable to the elongated reservoir defined by an elongated tube shaped member having at least one wall forming a forward rim and extending in a tubular fashion to a rearward end, and the at least one wall also forming a longitudinal slot for receiving the handle of the plunger, or a lever attached to said handle, and the slot disposed to allow said handle or lever to travel when a user pushes the handle of the plunger towards or away from the fluid transfer body end of the elongated reservoir; wherein fluid is drawn into the reservoir from a fluid supply through the side inlet by causing the plunger to travel away from the fluid transfer body, and wherein fluid is dispensed by causing the plunger to travel towards the fluid transfer body and out the head end.
