<P>PROBLEM TO BE SOLVED: To provide a spout cap which avoids uncertain attachment due to an interference with a nozzle to make the depression of a head impossible without fail. <P>SOLUTION: The spout 9 is formed by engaging a cap 6 holding a pump with a container 1 and fitting the head 8 with the forward projecting nozzle 7 to the front end of a jet pipe 5, which projects to be capable of moving up and down. The spout cap 10 includes a head cover 15 which has a square upper face 11 that is as wide as the diameter of a semicircular portion 11a corresponding to the head 8 and that extends to the front end of the nozzle 7 and a peripheral face 12 that covers the periphery of the head 8 except its front part, and an engaging back face 19 which extends down consecutively from the peripheral face 12 and is shaped in correspondence to the back face of the jet pipe 5 to engage removably with the peripheral face of the jet pipe 5. The height of the engaging back face 19 is equivalent to the distance between the head back face 8a and the cap upper face 6a. The level of the upper face 11 is so determined that the engaging back face 19 faces the head upper face 8b across a thin gap when engaged with the peripheral face of the jet pipe 5. <P>COPYRIGHT: (C)2007,JPO&INPIT |
