Supporting portions 2t and 2t of a rear portion 2z of an applying body holder 2 are advanced into an impregnated body 3 impregnated with a liquid L while a rear portion 4z of an applying body 4 having a plate shape and exhibiting capillarity is supported so as to be sandwiched or wrapped by the supporting portions 2t and 2t. The rear portion 4z of the applying body 4 can therefore be easily inserted into the impregnated body 3 without being bent, while protected by the supporting portions 2t and 2t. The liquid L in the impregnated body 3 is surely moved to the applying body 4, and the liquid L flows straight forward through an opening 2u at a rear end of the supporting portions 2t and 2t, so that the liquid L in the impregnated body 3 is moved smoothly.

Provided are: a writing implement in which a joint connecting an ink supply section and a ballpoint pen tip together is configured from three members. The three members configuring the joint are a substantially cylindrical center member, a substantially cylindrical surrounding member formed at the outer periphery of the center member, and an interposing member that is molded by a soft member molded so as to cover the outer periphery of the center member and the surrounding member. An annular gap section is provided between the center member and the surrounding member. The leading end of the ink supply section is fitted into the gap section. The joint is formed by two color molding. The center member and the surrounding member are molded by primary molding, and the interposing member is integrally molded onto the center member and the surrounding member by secondary molding.

A writing instrument includes a first reservoir for dispensing a first fluid having a first property of reflectivity. A first tip member is in fluid connection with the first reservoir. The first tip member has an end with a size and shape that corresponds to a response area of the response form. A second reservoir can be used for dispensing a second fluid, which is capable of modifying the first property of reflectivity when covering the first fluid. A second tip member is in fluid connection with the second reservoir. The second tip member has an end with a size and shape that corresponds to the response area of the response form.

A reservoir type writing pen having a micro-porous straight-liquid structure comprises a writing pen core (9); wherein the micro-porous straight-liquid structure includes an air pressure balance plug (3), a liquid storage pipe (11) configured for storing liquid ink, and a liquid guiding device configured for leading the liquid ink in the liquid storage pipe (11) into the writing pen core (9). The present application adopts the gap between the relaying pen core and the writing pen core, the ventilating core and the nano breathing plate to realize keeping the inner air pressure of the liquid storage space and the outside atmosphere pressure consistent. The writing pen of the present application has a simple structure, and the producing processes of the ventilating core have been matured, which can reduce the producing cost greatly.

A cosmetic applicator capable of stably applying a cosmetic even when the cosmetic contains large particles. A cosmetic applicator includes a barrel, a brush made of bundled fibers and provided in front of the barrel, a cosmetic accommodation portion arranged in a space behind the barrel, a guide that guides a cosmetic from the cosmetic accommodation portion to the brush, a collector that has a comb-shaped outer circumferential surface and that is disposed inside the barrel and at an outer circumferential portion of the guide, and a front barrel supporting the brush at a front portion of the barrel. A capillary force of the guide is 50 to 200 (mm) (as measured using purified water in an environment of 25 C.). (B)/(A) is 0.8 or greater, where (A) (mg) is an amount of cosmetic liquid discharged for 1 (m), and (B) (mg) is an amount of cosmetic liquid discharged for 1 (m) after 30 (m).
