Abstract
A wearable dispenser with a replaceable one-time-use reservoir device is taught, comprising a wrist-band allowing the wearable dispenser to be worn by a user; a base connected to the wrist-band; and a replaceable one-time-use reservoir. The replaceable one-time-use reservoir is comprised of a flexible bladder holding a substance to be dispensed, a housing with a rigid perimeter wall, a flexible top surface attached to the rigid perimeter wall and covering the flexible bladder, a one-way valve, an opening, and a substance to be dispensed. Typically, the substance to be dispensed is hand sanitizer. A user may use their fingertip to press the flexible top surface. Doing so creates additional pressure within the flexible bladder, causing the substance to be dispensed.
