    摘要： A bottle-shaped can includes a cap having an excellent sealing ability but easy to be opened. A top section includes a leading end section as an upper end of a neck portion, a diametrically-largest section formed beneath the leading end section, a diametrically-shrunk section extending downwardly from the diametrically-largest section, and an outer circumferential wall section extending downwardly from the diametrically-shrunk section. The leading end section, the diametrically-largest section, and diametrically-shrunk section form a smooth curved surface. A curvature of the diametrically-largest section in a cross-section is zero or negative value, given that a curvature of the diametrically-shrunk section is positive value. A flexion section is formed between the diametrically-shrunk section and the outer circumferential wall section. The outer diameter of the outer circumferential wall section in which the curvature is zero or negative value is larger than an outer diameter of the flexion section.

    摘要： A painting method and a painting apparatus for a band material that prevent a printing defect during a long-time operation by preventing agglomeration and adhesion of a thixotropic paint in a paint pan is disclosed. The liquid paint is discharged to the paint pan as a jet flow from a level lower than a liquid surface of a paint basin toward a bottom of the paint pan, thereby creating a bottom flow along the bottom of the paint pan and an upward vortex from the bottom along a side wall of the paint pan. The liquid paint overflows in an amount corresponding to a supplied amount to the paint pan from a front upper edge of the paint pan in a flowing direction of the bottom flow, thereby flowing the liquid paint continuously in the paint pan toward the front upper edge.

    摘要： A sealing plate including an explosion-proof valve whose opening pressure can be set easily, and whose groove will not be not ruptured by a repeated stress before reaching an opening pressure. The explosion-proof valve including a thin plate portion thinner than a plate; a valve portion formed by partially projecting the thin plate portion in a thickness direction to enhance a bending rigidity; and a groove drawn as a boundary between the valve portion and the thin plate portion to serves as a score line. A rupturable portion that is ruptured after the groove is ruptured is formed between a straight line and a folding line. The valve portion is bent along the folding line to open the explosion-proof valve when the rupturable portion is ruptured after the groove is ruptured.

    摘要： Container connector includes a base in which a flow path is formed, an engagement section disposed on a circle set to the base, a guiding section disposed continuously with the engagement section, and having a guide surface formed as a curved surface to guide the container to the engagement section and facing a side of an axis of the circle, and an arm provided in the base, and movably supporting the guiding section in a direction toward the axis of the circle and a direction away from the axis.
