  • Patent number: 7303349
    Abstract: 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 mechanism 10 which pressurizes an inside of ink accommodating tube 3 and includes a pressurizing chamber 14 communicating with the inside of the ink accommodating tube, an elastic spherical body 16 disposed to be pushed into the pressurizing chamber, a compression spring 17 that urges the spherical body in a direction to be released from within the pressurizing chamber, and a pressing stem 18 that moves the spherical body against the urging force of the compression spring into the pressurizing chamber in an airtight state.

  • Publication number: 20070147948
    Abstract: There is provided a solid paste dispenser which makes clear whether or not solid paste for replacement is retained on the side of the solid paste dispenser during replacing work of the solid paste so as not to cause a trouble that solid paste is crushed erroneously. The solid paste dispenser includes a slider 7 caused to ascend and descend within a main body cylinder 2 by rotating a tail wheel 3 mounted to one end of the main body cylinder 2 to rotate a screw rod 5 formed integrally with the tail wheel 3 within the main body cylinder 2, such that a front end 4a of a solid paste 4 mounted to the slider 7 is protruded from and retracted into the main body cylinder 2. The solid paste 4 is indirectly mounted to the slider 7 by retaining a rear end of the solid paste 4 in a solid paste receiving member 8 engaging the slider 7 in detachable manner.

  • Publication number: 20060266480
    Abstract: A coating film transfer tool has a container which can be opened and is composed of a container body and a cover member. The container can be loaded in exchangeable manner with a cartridge equipped with a feed reel having an unused transfer tape wound thereon. The unused transfer tape is equipped at its free end with a retaining member which is retained on a receiving portion of a take-up reel arranged in the container, thereby to facilitate the take-up of the transfer tape by the take-up reel.

  • Publication number: 20060204314
    Abstract: 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.

  • Patent number: 6270578
    Abstract: A transfer head 9 of a coating film transfer tool 1 includes a tape supply surface 11 in which a transfer object surface side thereof is flat and a tape winding surface 12 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 9 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.
