Abstract: A container cap, comprising a primary cap provided with an outlet opening in a top wall thereof, and fitted to a mouth of a container, a secondary cap hinged to the top wall of the primary cap, and rotatable between a closing position for closing the outlet opening and an opening position for exposing the outlet opening, and a slide member which is axially slidable along the primary cap, and is attached to a point of the secondary cap outside the hinged end thereof via a flexible connecting member. The flexible connecting member may be integrally molded with the secondary cap and the slide member. This container cap can reduce the possibility of inadvertently opening, and prevent the content from sticking to the finger used for operating the secondary cap.

Abstract: A filter device for use in a fuel tank, has a filter body having an upper wall and a lower wall, a guide portion extending through the filter body and having an intake hole at a lower portion of the guide portion near the bottom wall of the filter body, a suction pipe having a lower portion which is inserted into the guide portion, and spring means provided between the suction pipe and the filter body for biasing the filter body toward the bottom wall of the tank body.

Abstract: A thermal cut-off fuse of the class wherein the electric continuity between electrodes disposed inside a housing is maintained by conductor means at normal service temperatures and broken by the conductor means being fractured when the ambient temperature reaches a fixed level is improved by having the conductor means made of a metal capable of liquefying before the ambient temperature reaches the fixed level mentioned above and providing a thermal pellet faithfully fusible at the fixed level of temperature for the purpose of supporting in position the conductor means serving to maintain the electric continuity between the electrodes at normal service temperatures and thereby allowing the electric continuity between the electrodes to be broken at the fixed level of temperature by the thermal pellet being melted and deprived of its role of supporting the conductor means.
