The present disclosure relates to a sharp type paint marker pen in which the convenient use thereof is provided because an ink is easily discharged through the Bernoulli's principle in accordance with a pressing action of an ink tank, the operation efficiency thereof is increased, a relatively inexpensive polyester nib is also able to be used instead of an expensive acrylic nib, a product lineup is able to be expanded using a watercolor marker or the like when a brush nib is applied, a high viscosity ink is also able to be applied, and it is also able to be expanded into other industries such as manicure.

A liquid applicator device is disclosed for dispensing a liquid. A dispensing mechanism defines a valve body hollow. The dispensing mechanism receives the liquid from a liquid container. A closure engages with the liquid container. An applicator tip slidably engages within the closure. A flared peripheral shoulder is coupled to a valve element. The flared peripheral shoulder is impressed against the valve body hollow for preventing the liquid from exiting the dispensing mechanism. The flared peripheral shoulder is displaced for permitting the flow of the liquid from the dispensing mechanism and to the applicator tip. In a first embodiment of the invention, the flared peripheral shoulder includes a non linear protrusion for preventing leakage of the liquid from the dispensing mechanism. In a second embodiment of the invention, a valve flow regulator is coupled to the valve element for controlling the flow of the liquid from the dispensing mechanism.

A writing implement including a reservoir for storing a liquid, an applicator tip for depositing the liquid on a surface, a buffer connected to the reservoir and connected to the applicator tip so as to transport the liquid from the reservoir to the applicator tip, and a normally-open valve separating the buffer from the reservoir, the valve being configured to close, to prevent flow of the liquid from the reservoir to the buffer, in response to internal pressure within the reservoir exceeding a reference pressure outside of the reservoir by more than a predetermined amount.
