Description

[Detailed explanation of the idea] "Industrial application field" This case concerns a liquid dispensing cap.

``Prior art'' As this type of cap, for example,
There is a cap numbered 121062. The cap has an outward facing flange attached to its upper end that is fitted onto the upper end surface of the mouth and neck of the container body to engage the internally threaded tube with the inner surface of the mouth and neck, and a plug is inserted from the center of the bottom wall that closes the lower end surface of the female threaded tube. The opening is made up of a tube that fits into the opening and has a liquid outflow hole in the bottom wall surrounding the stopper, and an inward flange on the upper end of the peripheral wall that is screwed onto the outer surface of the neck of the container body. A tube to be attached to the outer surface of the mouth and neck, in which the outward flange of the inner fitting tube is held between the upper end surface of the mouth and neck, and a lower half tube of the nozzle is screwed into the female threaded tube, and the nozzle It consists of a cap-shaped member that hangs down from the outer periphery of the top wall that expands downward and outward from the outer surface of the upper end, and the lower end of the nozzle hole is closed with the plug,
When the cap-shaped member is screwed upward, the stopper is removed, and the liquid outlet hole in the bottom wall of the female threaded cylinder communicates with the nozzle hole, so that liquid can be poured out.

``Problem to be solved by the invention'' In the above-mentioned cap, the nozzle hole opens and closes by the screw raising and lowering of the cap-like member with the nozzle. It is difficult to tell whether the nozzle is closed or not, and since the female threaded tube and the nozzle are screwed together, liquid is likely to leak through the gap. It was necessary to provide an O-ring between the inner peripheral surface of the orientation flange.

The present invention eliminates the above drawbacks and rotates the rotating member located at the upper end of the cap in both forward and reverse directions.
The upper part of the nozzle enters and exits from the center of the top wall of the member, and the lower end of the nozzle is provided as a cylindrical piston to prevent liquid leakage.

"Means for solving the problem" Flange-shaped first top wall 2 placed on the top surface of the container mouth
A cylinder 5 to be fitted to the inner surface of the container mouth and neck is suspended from the inner circumferential edge of the container body, and the inner end of a plurality of connecting plates 6 protruding inward from the lower end of the cylinder at appropriate intervals allows the center axis of the cylinder to be fixed. A nozzle 8 that erects a male threaded cylinder from a main member 1 that is positioned on a line and erects the plug rod 7, and a cylindrical piston 9 whose inner and outer surfaces are fitted to the outer surface of the plug rod 7 and the inner surface of the cylinder 5 so as to be able to move up and down. and a rotating member 12 that covers the upper surface of the main member 1, and a second rotating member 12 of the rotating member 12.
A protrusion on the inner surface of the second peripheral wall 14 that hangs down from the outer periphery of the top wall 13 is rotatably fitted into a groove on the outer surface of the main member 1, and a through hole is bored in the center of the second top wall 13. 15 into which the male threaded cylinder of the nozzle is screwed together, and a rotation prevention means 10 is provided between the outer peripheral surface of the stopper rod 7 and the inner surface of the cylindrical piston 9, and the rotation member 12 is connected to the main member 1. When rotated in the forward direction,
The nozzle 8 rises until the top of the male threaded cylinder protrudes above the second top wall 13, at which time the nozzle hole opens, and when the rotating member 12 is rotated in the opposite direction, the top end of the male threaded cylinder moves into the through hole 15. The nozzle 8 is lowered until it enters the sheet means 11 for sealing the nozzle hole at this time.
was formed by a part of the stopper rod 7 and a part of the nozzle 8.

"Operation" When the rotating member 12 is turned in the positive direction relative to the main member 1 from the state shown in FIG. 1, the nozzle 8 rises as shown in FIG.
3. It protrudes upward, allowing the liquid inside the container (not shown) to be poured out. Rotating member 1 from the nozzle raised state
When turning 2 in the opposite direction, the nozzle 8 descends as shown in Figure 1.
As shown in FIG. 3, the upper end of the male threaded cylinder enters the through hole 15, and at this time, the inner surface of the nozzle hole contacts the upper outer peripheral surface of the stopper rod 7, and the sealing means 11 formed by these is closed, and the liquid is not poured out. It becomes impossible.

``Example'' The configuration will be described below with reference to the drawings. Reference numeral 1 denotes a main member, and this member extends from the outer peripheral edge of the brim-shaped first top wall 2 to be placed on the top surface of the mouth of the container body to the outer surface of the mouth and neck. A cylinder 5 into which the first circumferential wall 3 to be fitted is fitted, and from the inner circumferential edge 4 of the first top wall to the inner surface of the mouth and neck.
A plurality of connecting plates 6 are protruded inwardly from the lower end of the cylinder at appropriate intervals, and from the inner end of the connecting plates are plug rods positioned on the same axis as the cylinder. 7 standing up.

In the nozzle 8, the inner and outer surfaces of the cylindrical piston 9 are fitted to the outer surface of the stopper rod 7 and the inner surface of the cylinder to erect a male threaded cylinder.

Between the stopper rod 7 and the inner surface of the cylindrical piston, there is provided a structure that allows the nozzle to move up and down and prevents the nozzle from rotating.
A rotation prevention means 10 is provided which is formed by longitudinally disposing uneven stripes and engaging them, and a nozzle hole is opened in a part of the stopper rod and a part of the inner surface of the nozzle hole when the nozzle is raised. , sealing means 11 closed by lowering
is formed.

In the rotating member 12, a second peripheral wall 14 that hangs down from the outer periphery of a second top wall 13 that covers the upper surface of the main member 1 is rotatably fitted onto the upper outer surface of the main member. In the illustrated example, a short cylindrical portion is raised from the upper surface of the first top wall 2 of the main member, and a protrusion provided around the inner surface of the lower end of the second peripheral edge 14 can be rotated into a groove provided around the outer surface of the short cylindrical portion. It is fitted. A through hole 15 is bored in the center of the second top wall 13,
A short cylindrical portion 16 is provided vertically from the periphery of the through hole, and the male threaded tube of the nozzle is screwed into the short cylindrical portion. When the short cylindrical portion is not provided, the through hole 15 is a screw hole.

In the state shown in FIG. 1, the upper part of the male threaded cylinder of the nozzle 8 does not protrude from the upper surface of the second top wall 13, and by turning the rotating member in the forward direction, the upper part of the male threaded cylinder can be moved to the second peak as shown in FIG. Protrudes upwards from the wall. In this state, the sealing means 11 opens, allowing the liquid to flow out through the liquid outflow path between the rod portion 7 and the inner wall surface of the nozzle.
Further, by rotating the rotating member in the opposite direction, the upper end of the nozzle enters the second through hole 15, and at this time, the sealing means 11 seals a part of the inner surface of the nozzle hole.

As an example of the cap having the above structure, each member may be integrally molded from a synthetic resin material,
As shown in the figure, the sealing means 11 may have the upper end of the stopper rod formed with a tapered surface, and a tapered valve seat matching the tapered surface may be formed in the middle part of the nozzle hole. It may also be formed with an upwardly directed step portion 7a provided on the lower outer surface of the holder.

"Effect of the invention" The present invention has the above-described structure, and the cylindrical piston 9 of the nozzle is fitted between the stopper rod 7 and the cylinder 5, and the outer surface of the stopper rod 7 and the inner surface of the cylindrical piston 9 are connected. A rotation prevention means 10 is provided between them, a part of the stopper rod 7 and a part of the nozzle 8 form a sealing means 11, and a male threaded cylinder rising from the cylindrical piston is connected to the second top wall of the rotation member 12. 13 is screwed into the through hole 15 in the central part, and further, the protrusion provided on the inner surface of the second peripheral wall 14 of the rotating member 12 is rotatably fitted into the groove provided on the outer surface of the main member 1. Therefore, by rotating the rotating member 12 in both forward and reverse directions with respect to the main member 1, only the nozzle 8 moves up and down, and its rise allows liquid to be poured out through the nozzle hole, and its descent allows the nozzle hole to be poured out. It can be sealed tightly, and liquid leakage can be prevented from occurring between the cylinder and the cylindrical piston. When the rotating member 12 is rotated in the forward direction, the upper part of the male threaded cylinder protrudes above the second top wall 13, opening the nozzle hole, and when the rotating member 12 is rotated in the opposite direction, the male threaded cylinder is opened. The nozzle 8 descends until the upper end enters the through hole 15, and the sealing means 11 for sealing the nozzle hole at this time is formed by a part of the stopper rod 7 and a part of the nozzle 8. Therefore, the opening and closing of the nozzle hole can be determined by whether the upper part of the male threaded cylinder of the nozzle protrudes from the upper surface of the second top wall 13 of the rotating member 12, and the upper part of the male threaded cylinder protrudes from the second top wall 13. Since the liquid will be poured out in a state where
The second top wall does not get in the way when pouring out the liquid, making it easy to pour out the liquid.
