To provide a makeup tool that is excellent in design and can perform stable application of a cosmetic, the makeup tool includes a barrel cylinder storing the cosmetic; and an application part attached to one end of the barrel cylinder, in which the application part includes an applying element capable of feeding the cosmetic from the barrel cylinder to apply the cosmetic, and a retainer that holds the applying element, and the retainer is formed of a hard material presenting visibility.

Makeup tool

The liquid substance advancing container is constructed such that the piston is formed of a sealing part in a front part of the piston that comes in sliding contact with an inner wall of a reservoir of the barrel body and a bar member in the rear part of the piston that has a threaded section on the inner or outer periphery, is movable in a axial direction and is restrained form moving with respect to the rotational direction, a front bar-like part extended forward from the handle is formed with a threaded section that is directly or indirectly screw-fitted to the threaded section of the bar member in the rear part of the piston, and, as the handle is rotated relative to the barrel body, the piston advances and then after full advance of the piston the front bar-like part can extend and retract by multiple stages.

Liquid substance advancing container

To provide a puncture device which prevents components constituting a puncture device from being damaged by buckling (bending) etc., secures safety, and can be handled by a weak user easily. A puncture device is provided with an outer needle, an outer needle hub for retaining a base portion of the outer needle, an inner needle whose tip portion is inserted in the outer needle, an inner needle hub for retaining a base portion of the inner needle, an outer pipe fitted inside the inner needle hub so as to be moveable to and fro, and an inner pipe having a gripping device for gripping the outer needle hub and fitted inside the outer pipe so as to be moveable to and fro, and at least the outer pipe is formed of a soft synthetic resin.

Puncture device

A slide body () is arranged in a cut-away portion of a holder () under a clip () so as to not hinder writing or portability, and a safety mechanism is constituted so as to be engaged with the clip (). Due to functions of a knock rod cam () of a knock rod () and a knock cam () of a rotor (), further, the rotor () is rotated and moved forward responsive to each knocking operation, a refill () is brought to a writing position and a holding position alternately responsive to each knocking operation due to a cam mechanism provided in the inner wall of an inner cylinder () and a reactive force of a spring (). A slide body cam () provided on the slide body () is incorporated in a portion of the cam mechanism so that the knock type writing instrument thrusts the pen point out, by one knock even after the safety operation.

Knock type writing instrument

A refill of a low viscosity water-based ink ballpoint pen is provided with a housing, a pen tip attached to a front end of the housing, an ink tank () formed inside the housing, an ink guide member guiding ink in the ink tank () to the pen tip, and an air passage formed between the ink tank and the pen tip in the housing and connecting the ink tank and outside of the housing. The inside of the ink tank is divided by partition walls () into a plurality of ink chambers arranged in the longitudinal direction, and the ink guide member is used to guide the ink in these ink chambers from the ink chambers close to the pen tip successively to the pen tip. A substantially uniform clearance () is provided over the entire circumferences between the outer circumferential surface of each partition wall () and the inner circumferential surface of the ink tank (). A ring-shaped ink film formed at each clearance () is used to hold the ink in each ink chamber. Air flows into the ink chamber through the clearance ().

Writing implement

Upon depressing a knock rod in a state of writing of FIG.A, a cam protuberanceof a rotor turns rightward to assume a position shown in FIG.B. Upon removing a finger, the cam protuberanceturns sliding on a tilted surface, arrives at a position shown in FIG.C through a first vertical motion (distance d) and, further, arrives at a position shown in FIG.D through a second vertical motion (distance e). Here, a tilted surface of cam protuberancecomes in collision with a tilted surface of an inner cylinder camtwice, and shocks are transmitted to a refillBy forming a step between the front half and the rear half of the tilted surface of the inner cylinder camhowever, a distance of vertical motion of the cam protuberanceeach time is shortened to decrease the shock of collision imparted to the refill each time.
