  • Patent number: 5052837
    Abstract: A makeup liquid container designed to enable scraping a makeup liquid off the inner surface of the container. The container has a container body with an opening, a cap fitted on the container body so as to close the opening, an applicator shaft fixed at its one end to the container body and adapted to be inserted into the container body when the cap is fitted on the container body, and an applicator such as a brush fixed to the other end of the applicator shaft. The container further has a slider capable of sliding along the inner surface of the container body so as to scrape makeup liquid off the inner surface of the container body. The sliding motion of the slider is caused by the applicator shaft which is moved into and out of the container body when the user pulls or presses the cap up and down or, alternatively, the slider is freed from the applicator shaft so as to move up and down in the container body as the container body is shaken.

  • Patent number: 5037227
    Abstract: A casing capable of opening a lid and protruding a cosmetic material contained in the casing by one operation, having a simple and improved overall appearance and capable of being reduced in size when the cosmetic material is retracted, the casing having: a tubular main body having an elongated aperture extending in the axial direction; a closed inner tube fitted in the tubular main body so that it can slide therein ion the axial direction, the inner tube having an engaging projection projecting to the outside of the tubular main body through the elongated aperture; a screw tube rotatably fitted around the tubular main body, the screw tube having an inner screw groove in which the engaging projection of the inner tube is fitted so that the inner tube can be lifted as the screw tube rotates in one direction; a tubular member fitted around the screw tube so that the screw tube can rotate relative to the tubular member, the tubular member being fixed to the tubular main body; and slid pivotally mounted for closi

  • Patent number: 4528892
    Abstract: A hydraulic circuit system of a construction machine having first and second hydraulic circuit, and a bypass circuit for connecting the first and second circuits together. The first circuit includes a first hydraulic pump and a first valve group having a plurality of directional control valves for controlling a flow of hydraulic fluid from the first pump, and the second circuit includes a second hydraulic pump and a second valve group having a plurality of directional control valves for controlling a flow of hydraulic fluid from the second pump. A plurality of actuators are driven by the hydraulic fluid supplied from the first and second pumps through the valves. The bypass circuit includes a bypass line for connecting the first travel valve in series with the second travel valve in a position downstream thereof through the selecting valve.
