  • Patent number: 6152632
    Abstract: To make full use of a rod-like glue contained in a cylindrical dispenser main body of a glue dispenser to its final portion, a spiral member of a rotary operator element of the glue dispenser has a spiral outer diameter which is set to be equal to or larger than 30% and equal to or smaller than 80% of the outer diameter of rod-like glue, and a spiral pitch which is set to be equal to or larger than 50% and equal to or smaller than 300% of the spiral outer diameter. The spiral member is directly screwed to the rod-like glue integrally attached to a slider coupled with a bottom portion of the glue by elastic retaining pieces by which it is not necessary to form a top face of the slider in a recessed shape. The rod-like glue can be extracted and retracted from and to a dispenser main body by moving up and down the glue by rotating the rotary operator element.

  • Patent number: 6059002
    Abstract: An application tool having a container enclosing a replaceable cartridge body, with the cartridge body and container integrally and strongly fixed to each other. A slide plate sliding in a narrow groove of a lock portion pierced in a side surface portion of the application tool container is brought into contact with a supporting portion connecting a cartridge body and a transfer head in such a manner as to freely slide, thereby integrally and strongly fixing the application tool container and the cartridge body. Accordingly, the transfer head is prevented from deflecting during use of the application tool, thereby solving the problem of tape breakage experienced by conventional application tools during transferring and applying a paint. Further, the application tool can be smoothly operated.
