A paint applicator, kit and methodology for using the same is disclosed. For example, a paint applicator that allows a user to load a desired amount of paint, such as a water based or other low VOC paint, into the paint applicator and an advancement mechanism that dispenses paint at a rate controllable by the user is disclosed. The advancement mechanism can include a system that translates a rotational force applied to an end cap of the applicator into a linear force that advances a piston which in turn applies paint to an applicator portion. The paint applicator may be reusable or may include a ratchet system that allows for only one time use. The methodology and kit can incorporate a syringe for loading paint into the paint applicator, thus reducing the loss of paint through spilling.

The brush structure: a) contains the toothpaste; b) dispenses the toothpaste; and, c) generates an abrasion used to clean the teeth of the patient.

A dispensing-by-rotation liquid cosmetic container includes a pen body, a piston, a threaded rod and a threaded cylinder, which are coaxially arranged. A pen cap is sleeved on the front end of the pen body. A receiving space is provided inside the pen body. A bristle assembly is fixedly arranged at the front end of the receiving space. The pen cap is sleeved on the bristle assembly. The piston is provided in the receiving space. The piston is in an interference fit with the inner wall of the pen body and moves axially along the inner wall of the pen body, and the piston is fixedly connected to the threaded rod. The threaded rod is rotatably connected to the threaded cylinder by an internal thread. The threaded cylinder and the pen body are axially snap-fitted and rotate relative to each other in the circumferential direction.

Tooth cleaning devices for portable, discrete use to improve dental hygiene as well as cosmetic appearance of teeth and processes for using same. The devices enable discrete cleaning of teeth after drinking dark-colored beverages or after eating food in social settings when conventional teeth cleaning devices are unavailable or inconvenient. In particular, these devices are designed for multiple uses, so that the same device may be used for teeth cleaning on multiple occasions.
