Description

[Detailed explanation of the idea] "Industrial application field" Pertains to a cap with a spout.

``Prior art'' For example, as a cap with a pouring stopper,
The invention of No. 50461 is known. The cap has a peripheral wall that is screwed to the container mouth and neck hanging from the outer periphery of the top wall, an opening in the center of the top wall, a guide tube hanging down from the periphery of the opening, and a bottom wall at the lower end of the guide tube. A rod plug is erected from the center to the upper part of the guide cylinder, and a plurality of through holes are bored in the bottom wall around the lower end of the rod plug, and then lowered outward in the radial direction to the top wall around the opening. A part of the upper end of an elastically deformable nozzle fitted vertically between the cap body having a groove formed therein, the outer surface of the rod stopper, and the inner surface of the guide cylinder is passed through the groove to the outside. It consists of an operating member that projects a lever, a flow path is provided between the outer surface of the rod plug and the inner surface of the nozzle, and an inwardly flange-shaped valve seat is provided on the inner surface of the upper end of the nozzle, and discharge is made between the valve seat and the upper end of the rod plug. A valve is formed, and when the outer end of the lever is pushed down, the nozzle is pulled up, opening the discharge valve, and the contents stored in the container can be poured out through the inside of the nozzle.

``Problems to be solved by the invention'' The above-mentioned conventional cap is fitted into a guide cylinder,
and a discharge valve that is formed by pulling up a nozzle that fits on the outer surface of a rod plug standing up in a guide cylinder by pushing down a lever that projects outward from the upper end of the nozzle, thereby forming an upper end of the rod plug and a valve seat on the inner surface of the upper end of the nozzle. Since the nozzle is provided so as to open, the upper part of the nozzle is curved when the lever is pressed down, which has the drawback of increasing frictional resistance between the inner surface of the guide cylinder and the outer surface of the nozzle.

The present invention is designed to facilitate the operation of moving the nozzle up and down.

"Means for Solving the Problems" The peripheral wall 9 for fitting the container mouth neck 3 is suspended from the outer periphery of the top wall 7, and the center part of the top wall 7 is bulged upward to form a cap-like and rectangular cylindrical top part. A cap body 1 having a cylinder 12 formed therein, a guide hole 13 formed at the top of the mounting cylinder 12, and mounting holes 14, 14 formed on the front and rear or left and right surfaces, respectively, and a container fitted onto the inner surface of the upper end of the peripheral wall 9. A cylindrical guide tube 16 with a bottom is inserted through the center of the substrate 15 for closing the upper end surface of the body mouth and neck, and a rod plug 17 is erected from the center of the bottom plate of the guide tube, and a bottom plate surrounding the rod plug is installed. A plug member 4 having a through hole 18 formed therein;
The nozzle 5 has a lower cylinder part fitted into the guide cylinder 16 so as to be movable up and down, and a pair of flanges 20, 20 are attached to the intermediate cylinder part vertically spaced apart, and the nozzle 5 is mounted in the mounting holes 14, 14. Disc-shaped support shafts 23, 23 attached to the inner surfaces of the lower ends of the arms 22, 22 hanging down from both ends of the top plate 21 placed on the cylinder 12 are rotatably fitted, and the inner end surfaces of both support shafts are rotatably fitted. The engaging protrusions 24, 24 protruding from a part of the periphery of the above-mentioned brim 20, 20
and an operating handle 6 slidably engaged between the operating handle 6 and the operating handle 6 for the cap body 1.
When raised and lowered, the engaging protrusions 24, 24 lower and raise the nozzle 5 via the flanges 20, 20, and the upper end of the nozzle 5 is drawn out and retracted from the guide hole 13 by the vertical movement of the nozzle. Along with the rod stopper 1
7 is formed so that the lower end of the nozzle hole can be opened and closed.

``Operation'' In the lowered state of the nozzle 5 shown in FIG. 3A, the lower end of the nozzle hole is closed by the rod stopper 17, and the liquid in the container body 2 does not flow out. When the operating handle 6 is tilted down from this state as shown in FIG. 3b, the engaging protrusion 24 of the handle,
24 moves upward in an arc shape due to the rotation of the support shafts 23, 23, pushing up the nozzle 5 via the flanges 20, 20, and at this time, the lower end of the nozzle separates from the rod stopper 17 and the nozzle hole opens. When the operating handle is returned to its original position, the nozzle descends again and the lower end of the nozzle hole is inserted into the rod stopper 17.
is closed.
