## Abstract

The dispensing device allows for application of nourishing compounds, such as microcapsules, during rest. The elements of the dispensing device that contain the nourishing compounds are separable from the body of the device. Thus, the body of the device is washable without risk of washing away the desirable compounds. The device can take one of multiple embodiments. In the first embodiment, a lower layer forms the body of the device. The body is preferably formed from a compressible material, such as memory foam or other types of polyurethane foam. The upper layer includes a multiplicity of internal reservoirs that contain the nourishing compounds and/or microcapsules. When a user places her head on the device, the downward force created against the relevant storage body pushes the compounds/microcapsules out of the internal reservoir, exiting through the orifices and into the user's skin.

## Claims

### Claim 1

A compressible device with integrated microcapsule reservoirs, the device comprising:
a body;
a discrete and removable reservoir for storage of microcapsules, the discrete and removable reservoir surrounded by the body and removeable from the body;
the microcapsules formed from:
a water-soluble biopolymer solution;
an oil;
and a salt;
whereby the microcapsules are a membrane surrounding a skin-nourishing chemical;
a second reservoir;
the discrete and removable reservoir and second reservoir connected by a branch;
the branch carrying microcapsules from the reservoir to the second reservoir when a force is applied to the reservoir; and
an actuation mechanism for discharge of the microcapsules through orifices present in the reservoirs.

### Claim 2 (depends on 1)

The device of claim 1 wherein the water-soluble biopolymer solution further comprises ascorbic acid.

### Claim 3 (depends on 1)

The device of claim 1, wherein the body further comprises:
a recess;
the discrete and removable reservoir sitting within the recess.
