Nozzle Mounting Structure of Component Container

摘要

Provided is a nozzle mounting structure of a component container by which a nozzle configured to rotate between a first position and a second position may be mounted to a housing without the need for a high processing precision and a high assembly precision. A pair of shaft portions support a body with the nozzle unitarily formed therewith. The nozzle rotates between the first position and the second position. A curved convex surface provided on the body is pressed against a curved concave surface provided on a first bottom wall portion of a housing by a pressing force imparted from a support portion.

主权项

1. A nozzle mounting structure of a component container including a housing including a cylindrical portion having an opening portion at one side thereof, a chamber provided inside the housing and configured to contain a predetermined component, and a bottom wall portion closing the other end of the cylindrical portion and having a discharge port configured to discharge a component from the chamber, wherein the nozzle mounting structure is configured to dispose a nozzle at a first position which causes the nozzle to close the discharge port before the component is discharged from the discharge port and to dispose the nozzle at a second position which allows the discharge port and a passage of the nozzle to communicate with each other when the component is discharged from the discharge port,
the nozzle mounting structure comprising:
a body including:
a closing portion unitarily formed with the nozzle and configured to liquid-tightly close the discharge port when the nozzle is disposed at the first position; andan entrance portion where an entrance of the passage of the nozzle is formed; and a body holding structure configured to hold the body to allow the nozzle to rotate between the first position and the second position with respect to the center of rotation, wherein: the body includes a curved convex surface curved in an arc with respect to the center of rotation; the entrance opens in an end portion of the curved convex surface to form the entrance portion; the closing portion is formed by the curved convex surface except the entrance portion; a curved concave surface is formed on an outer surface of the bottom wall portion of the housing such that the curved convex surface slides thereon, and the discharge port opens in the curved concave surface; the body holding structure includes:
a pair of shaft portions provided at the body and extending in opposite directions along a line passing through the center of rotation; anda support portion provided at the bottom wall portion and configured to rotatably support the pair of shaft portions and to impart on the body a pressing force for pressing the curved convex surface against the curved concave surface.
