## Abstract

A droplet for delivering toothpaste to a user can be provided. The droplet can include a dissolvable outer membrane defining a volume with toothpaste inside the volume. The outer membrane can be formed from dissolvable film strip technology and include a tail or corner portion, which is configured to be embedded into the bristles of a toothbrush. In one aspect of this embodiment, the outer membrane of the droplet can form a pillow-like shape. The droplet further can include one or more extensions coupled to the outer surface of the outer membrane, where the one or more extensions can have a triangular shape, a barb shape or the like. In one aspect of this embodiment, the droplet further can include a logo, a cartoon character, a word or the like printed on the outer membrane. The plurality of extensions can form irregularities on the outer surface of the body section of the outer membrane.

## Claims

### Claim 1

A droplet comprising:
a dissolvable outer membrane defining a volume;
toothpaste inside the volume;
wherein the outer membrane is formed from dissolvable film strip technology; and
wherein the dissolvable film strip technology is polyvinyl alcohol.

### Claim 2 (depends on 1)

The droplet of claim 1, wherein the outer membrane forms a pillow-like shape.

### Claim 3 (depends on 2)

The droplet of claim 2, further comprising a plurality of extensions on the outer surface of the outer membrane.

### Claim 4 (depends on 3)

The droplet of claim 3, wherein the plurality of extensions have a triangular shape.

### Claim 5 (depends on 3)

The droplet of claim 3, wherein the plurality of extensions have a barb shape.

### Claim 6 (depends on 3)

The droplet of claim 3, wherein the plurality of extensions forms irregularities on the outer surface of the outer membrane.

### Claim 7 (depends on 3)

The droplet of claim 3, wherein the outer membrane includes one of a logo, a cartoon character and a word.

### Claim 8

A method of cleaning teeth, the method comprising:
providing a droplet, the droplet including
a dissolvable outer membrane defining a volume;
toothpaste inside the volume;
wherein the outer membrane is formed from dissolvable film strip technology; and
wherein the dissolvable film strip technology is polyvinyl alcohol;
placing the droplet onto the bristles of the toothbrush;
releasing the toothpaste from the outer membrane into the bristles of the toothbrush; and,
cleaning the teeth with the toothpaste.

### Claim 9 (depends on 8)

The method of claim 8, wherein the releasing the toothpaste from the outer membrane into the bristles of the toothbrush includes dissolving the dissolvable outer membrane with one of water and saliva.

### Claim 10 (depends on 8)

The method of claim 8, wherein the outer membrane forms a pillow-like shape.

### Claim 11 (depends on 10)

The method of claim 10, wherein the droplet further includes a plurality of extensions on the outer surface of the outer membrane.

### Claim 12 (depends on 11)

The method of claim 11, wherein the plurality of extensions have a triangular shape.

### Claim 13 (depends on 11)

The method of claim 11, wherein the plurality of extensions form irregularities on the outer surface of the outer membrane.

### Claim 14 (depends on 11)

The method of claim 11, wherein the plurality of extensions have a barb shape.

### Claim 15 (depends on 11)

The method of claim 11, wherein the outer membrane includes one of a logo, a cartoon character and a word.
