## Abstract

The present invention includes improvements to a device with bristles that makes it possible to perform oral hygiene tasks to remove quickly impurities in the oral cavity, in particular when the user is travelling and does not carry a toothbrush and, due to time constraints, requires quick and effective cleaning. The cleaning device may also include luffa sponges, water-soluble films, spheres with toothpaste or channels that provide flexibility to a membrane which, when bending, generates a vacuum and is placed on the tongue in order to be used as a toothbrush handle. The device provides a better fitting and handling in the mouth of a user, since it avoids the generation of vacuum when actuated, and also has a membrane surrounded by a cylindrical section that allows its handling since it adapts to the tongue.

## Claims

### Claim 1

(canceled)

### Claim 2

(canceled)

### Claim 3

(canceled)

### Claim 4

(canceled)

### Claim 5

A disposable cleaning device for oral hygiene comprising:
a base;
a plurality of rows made of flexible irregular bristles extending along the periphery of said base;
a membrane disposed at a bottom end and substantially in a center of said base;
a cylindrical section disposed at the center of said base, the cylindrical section contains said membrane; and
at least one perforation disposed between each apex of said base and said cylindrical section;
wherein said at least one perforation being is adapted to prevent the disposable cleaning device from sticking to walls of the oral cavity when used due to absence of air.

### Claim 6

The disposable cleaning device according to clam 5, wherein said base has a triangular prism shape.

### Claim 7

The disposable cleaning device according to clam 5, wherein said base, said membrane, said bristles, and said cylindrical section form a single piece and are made of the same material.

### Claim 8

The disposable cleaning device according to clam 5, further comprising sections of luffa sponge adhered to said base for the oral cleaning.

### Claim 9

The disposable cleaning device according to clam 5, said membrane comprises a perforation at a center section through which a capsule containing dentifrice, astringent solutions, gels, an oral cleaning composition, or a medication, is placed, which are dissolved by saliva to cause the bristles move gently inside the mouth.

### Claim 10

The disposable cleaning device according to clam 5, wherein some of said bristles are longer and pointed to enter areas difficult to access.

### Claim 11

The disposable cleaning device according to clam 9, wherein said perforation allows a user to breathe in case of accidental ingestion of said device.
