An applicator in which an applying body consisting of a brush is surely attached to a front barrel to solve a problem that a part of the brush remains stuck inside the front barrel to cause failure of attachment when the applying body is being attached to the front barrel. The applicator includes a front barrel provided on the front end side of a rear barrel, and an applying body formed of a brush with a flange portion at its rear end and arranged inside the front barrel. A receiving part of the flange portion of the applying body and the inner face of the front barrel are in contact with each other in a non-surface contact manner.

A care instrument arranges one or more driving components, each corresponding to a storage container stored with a care product which can be used for caring or adding aroma for the user. Each driving component takes out the care product from the corresponding storage container and transports it to the surface of the housing through one or more outlets. A control component controls the driving components to deliver the care products to the surface of the housing in a timed and quantitative manner for precise delivery of the care products. A massage component is operated in synchronization with the driving components so that the care products are transported to the surface of the housing and uniformly dispersed by the massage component for easier application to the face or the body, thereby effectively improving the user experience.

A nib for a valve-free free ink writing felt pen including a first end configured to deliver ink to a writing support and second end, opposite the first end, configured to be inserted in a nib receiving part of the valve-free free ink writing felt pen, the first end and the second end defining an axial direction of the nib, the nib including a main body made of porous hydrophilic material and including one or more insert made of porous hydrophobic material, the one or more insert being configured to allow intake of air from the outside of a free ink tank of the valve-free free ink writing felt pen into the free ink tank and avoid ink leakage outside the free ink tank. A valve-free free ink writing felt pen including a nib.

An integrated highlighting marker includes a multi-component marker ink comprising a base colorant and a tinting colorant. The marking system also includes a highlighting component configured to transform the base colorant from a first colored state to a second colored state based on the tinting colorant. The highlighting component may be configured to transform the primary base colorant from a colored state to a transparent state to reveal the tinting colorant.

Provided is a fiber-bundled part for writing instruments having excellent strength and durability, as well as a pen tip and a writing instrument using the fiber-bundled part, which can be suitably used for pen tips, ink feed cores and relay cores of writing instruments such as marking pens and felt-tip pens. The fiber-bundled part for writing instruments of the present disclosure is used for the ink feed core leading to the pen tip or a writing pen core, and comprises a multifilament of long fibers having different melting points, and the multifilament at least contain crimped fibers.

A direct-liquid writing instrument includes a penholder, an ink feeder and a nib. One end of the penholder is provided with a writing portion, and the other end of the penholder is provided with an ink storage portion. The nib is partially inserted into the writing portion. The direct-liquid writing instrument also includes a first baffle and a second baffle that are spaced apart from each other to form an air barrier layer. The first baffle is in contact with the ink of the ink storage portion, and the second baffle is adjacent the writing portion. Additionally, the first baffle is provided with a first air-guiding channel, and a second air-guiding channel is provided between the second baffle and the ink feeder. The ink feeder passes through the first baffle, the air barrier layer, and the second baffle to deliver the ink to the nib.

A heat reactive composition and applicator apparatus and method are set forth. The heat reactive composition is applicable to the surface of an existing substrate to permanently scorch the existing substrate at places where contact with the composition of matter is effected. The exothermic reaction of the composition of matter constrains the reaction to portions of the substrate that are in immediate contact with the composition only. Intricate patterns and designs are thereby permanently transferrable onto or into the surface of the existing substrate by action of heat with a controlled and deliberate intent.
