Description

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

``Prior Art'' As a conventional liquid dispensing cap, for example, the device disclosed in Japanese Utility Model Application Publication No. 52-77846 is known. The liquid dispensing cap has a flexible and elastic cylindrical body whose lower part is fitted onto the outer surface of the neck of the container mouth, and an inverted cap-shaped wall having a concave portion on the upper side is connected to the upper surface of the cylindrical body. Then, a protrusion is erected from the center of the bottom of the inverted cap-shaped wall, and a pull-up plate is protruded from the side of the protrusion in the radial direction of the inverted cap-shaped wall with its lower surface continuous with the bottom, and the pull-up plate is A through-hole is bored in the circumferential wall of the cylindrical body as an extension of the cylindrical body, and the hole is closed at the upper part of the circumferential wall of the inverted cap-shaped wall. The inverted cap-shaped wall is deformed through the upper plate to communicate the through hole with the inside of the container.

"Problems to be Solved by the Invention" The conventional liquid dispensing cap described above is difficult to manufacture because it is formed of one member and has a complicated structure. In addition, if it is made of synthetic resin, it is necessary to provide thin hinges at various points in the elastically deformable portion of the inverted cap-shaped wall, which makes the structure even more complicated. Furthermore, when the bottom of the inverted cap-shaped wall on the pulling plate side is pulled up due to the protrusion collapse, a force is applied to push down the bottom end of the protrusion as a reaction. There was a risk that the bottom of the shaped wall would be pushed down and elastically deformed, resulting in incomplete opening of the through hole by the pull-up plate.

This proposal solves the above drawbacks.

"Means for Solving the Problem" A first cap-shaped part 4 is bulged upward from the upper end of a peripheral wall 2 to be fitted into the mouth of the container via an inward flange 3, and the top of the first cap-shaped part is Liquid spout hole 7 in the center of the wall
The synthetic resin cap main body 1 having a hole therein is engaged with the lower surface of the inward flange, and the upper surface of the outward flange 13 attached to the lower end of the second cap-shaped part 12 is engaged, so that the outward flange is connected to the upper end of the peripheral wall. The upright peripheral wall part 1 of the second cap-shaped part is fitted into the inner surface of the second cap-shaped part and stands up with a gap 17 between it and the upright peripheral wall part 5 of the first cap-shaped part.
4, an appropriate number of window holes 18 are bored in the top wall 15, and the outer periphery of the top wall 15 connected to the upper end of the upright peripheral wall is brought into watertight surface contact with the inner surface of the outer periphery of the top wall of the first cap-shaped portion; Second
An inner lid 11 made of synthetic resin is formed by curving the central part of the top wall of the cap-shaped part downward and positioning the liquid spout hole 7 above the curved part, and the second cap-shaped part makes surface contact with the inner lid 11. 1
A thin wall portion 8 is provided slightly below the cap-shaped portion, and a bar-shaped handle 9 extends outward from the thin wall portion, and a protrusion 10 extends inward.
By respectively protruding and moving the outer end of the rod-like handle, the protrusion 10 elastically pushes the second cap-shaped portion into the surface contact portion, forming the gap 17 and the curved portion inner space 16. This made it possible to form a passageway that communicates the two.

"Operation" When the present cap is fitted into the mouth of the container body, a gap 17 and a space 16 are formed by the surface contact portion between the outer periphery of the second cap-shaped part top wall part 15 and the inner surface of the first cap-shaped part. is closed, and therefore, the liquid inside the container does not flow out from the liquid spout hole 7 communicating with that space. Since a passage is formed in the closed part by elastic pushing, the liquid can flow out, and by returning the rod-shaped handle 9, it can be closed again.

"Example" 1 is a cap body made of synthetic resin. The cap body has a peripheral wall 2 which is screwed into the neck of the container body, and a first cap-shaped portion 4 is bulged upward from the upper end of the peripheral wall via an inward flange 3. The first cap-shaped portion is formed by an upstanding peripheral wall 5 and a spherical top wall portion 6, and a liquid pouring hole 7 is bored in the center of the top wall portion. Further, a thin wall portion 8 is formed in a part of the connecting portion between the upright peripheral wall portion and the top wall portion, and a bar-shaped handle 9 extends outward from the thin wall portion, and a protrusion 1 extends inwardly from the thin wall portion.
0 is made to stand out. The rod-like handle 9 is provided so that by moving its outer end, the inner end of the protrusion moves in the opposite direction to the outer end.

An inner lid 11 is mounted inside the cap body. The inner lid is also made of synthetic resin, and has an outward flange 13 attached to the lower end of the second cap-shaped portion 12. The outward flange is fitted into the inner surface of the upper end of the peripheral wall 2 by engaging the upper surface of its outer periphery with the lower surface of the previously described inward flange. The second cap-shaped portion also has an upstanding peripheral wall portion 14 and a top wall portion 15, and the center portion of the top wall portion is curved downward to form a space 16 within the curved portion. The outer circumferential portion of the top wall portion is connected to the upright peripheral wall portion, and the connecting portion is curved in a spherical shape. A gap 17 is formed between each of the upright peripheral wall parts 14 and 5 of the second cap-shaped part and the first cap-shaped part, and the outer peripheral part of the top wall part of the second cap-shaped part It is in watertight surface contact with the inner surface of the cap-shaped part.
Furthermore, a window hole 18 is bored in the upright peripheral wall portion.

The aforementioned protrusion 10 can be elastically pushed into the second cap-shaped portion that makes surface contact by moving the rod-like handle 9, and by this pushing, a passage communicating between the gap 17 and the space 16 is formed. It will be set up so that

"Effects of the invention" Since the present invention has the above-described structure, the structure of the cap body 1 and the inner lid 11 is simple and easy to manufacture, and the protrusion 10 can be moved to the second cap-shaped part of the inner lid by operating the rod-shaped handle 9.
2 is pushed in elastically, the liquid spout 7 can be reliably opened. Further, by changing the lengths of the rod-like handle and the protrusions, the operating load on the rod-like handle can be appropriately set.
