Abstract: A trigger-type liquid sprayer of the present invention is provided with a liquid sprayer body 2 having a nozzle 21 and a trigger lever 22 and a shroud 3 covering the liquid sprayer body 2 and sprays a liquid from a spray hole 211 in the nozzle 21 by a pulling operation of the trigger lever 22. The nozzle 21 is rotatable with respect to the liquid sprayer body 2 and provided so as to open/close a flow passage for the liquid according to a rotational position of the nozzle 21 when an operation lever 24 mounted on the nozzle 21 is rotationally moved, and an abutment portion 31 for positioning the nozzle 21 at a position where the flow passage is opened through abutment of the operation lever 24 is provided at the shroud 3.

Abstract: A cap which has a female screw in the inner peripheral surface and which is to be screwed on a port neck part of a container main body holding a predetermined liquid, wherein a plurality of ribs radially extending astride from an inner surface of a top surface part of the cap to an inner surface of a peripheral wall part and integrally projecting inwards are formed on a peripheral edge part of the inner surface part. A female screw is a screw in the form of two threads composed of spiral mated ridges of two threads, for example. The liquid held in the container main body is, for example, a chlorine-based bleach which contains a surface active agent and a sodium hypochlorite. The mated ridges each are 80 to 120 degrees in thread angle ? and 1 to 15% of a valley radius of the female screw in thread height H.

Abstract: A cap 10 which has a female screw 14 in the inner peripheral surface and which is to be screwed on a port neck part 13 of a container main body 11 holding a predetermined liquid, wherein a plurality of ribs 18 radially extending astride from an inner surface of a top surface part 16 of the cap 10 to an inner surface of a peripheral wall part and integrally projecting inwards are formed on a peripheral edge part 17 of the inner surface of the top surface part 16. A female screw 14 is a screw in the form of two threads composed of spiral mated ridges 14a, 14b of two threads, for example. The liquid held in the container main body 11 is, for example, a chlorine-based bleach which contains a surface active agent and a sodium hypochlorite. The mated ridges 14a, 14b each are 80 to 120 degrees in thread angle ? and 1 to 15% of a valley radius of the female screw 14 in thread height H.

Abstract: After a clinker sintered in a kiln is fluidized and mixed in a fluidized mixing and cooling zone provided before a grate cooling zone, the clinker is supplied to the following grate cooling zone and is cooled therein. The cooling air for fluidizing, mixing and cooling the clinker is supplied by successively switching and controlling the injection of the high pressure cooling air from the rows of the high pressure nozzles at the side walls towards the central rows in the fluidized mixing and cooling zone.
