Tombow Pencil Co., Ltd.

Yasuo Murakoshi

a pen adapted to be pressurized and capable of being manufactured inexpensively, with which ink can be smoothly supplied and an excessive pressurization within an ink accommodating tube and the leakage of ink can be prevented, as well as a pen that can be easily used in a state that a pen tip is directed upwardly. The pen comprises a pressurizing pump mechanismwhich pressurizes an inside of ink accommodating tubeand includes a pressurizing chambercommunicating with the inside of the ink accommodating tube, an elastic spherical bodydisposed to be pushed into the pressurizing chamber, a compression springthat urges the spherical body in a direction to be released from within the pressurizing chamber, and a pressing stemthat moves the spherical body against the urging force of the compression spring into the pressurizing chamber in an airtight state.

A solid paste dispenser and a slider for use therewith that enable the effective use of solid paste for sticking purposes by reducing any paste remaining unused, while not damaging a paper or like surface. The solid paste dispenser has a slider holding a stick of solid paste thereon, and the slider can be raised and lowered in a cylindrical body by its threaded engagement with a screw rod forming an integral part of a tail plug attached to one end of the cylindrical body so that the solid paste may have a distal end free to protrude from the cylindrical body and retract thereinto. The slider has a plate portion and a cylindrical portion projecting from the center of the plate portion on its side holding the solid paste thereon, and the screw rod extends through the cylindrical portion in a threadedly engaged relation therewith. The cylindrical portion has a radially outwardly extending engaging protrusion that is deformable at least at its outer edge in the direction of the longitudinal axis of the cylindrical portion.

A transfer head,of a coating film transfer tool,includes a tape supply surface,in which a transfer object surface side thereof is flat and a tape winding surface,in which a top end of an opposite side thereto is curved such that it is swollen outward. Both the surfaces intersect with each other so as to form a transfer edge,in a straight line. As a result, a beginning point of the coating film on the coating film transfer tape can be confirmed securely and the stiffness of the transfer head is improved thereby making it possible to cut the coating film sharply.
