Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a liquid dispensing cap, and more particularly to a liquid dispensing cap having a valve body.

[Conventional technology]

Hitherto, as this type of liquid dispensing cap, those described in Japanese Utility Model Publication No. 56-51008 and Japanese Utility Model Publication No. 57-37724 are known.

What is described in Utility Model Publication No. 56-51008 is
As shown in FIG. 5, the inner cap 21 is fitted into the cap body 3 in which the spout 4 is formed, and the outlet 22 is formed in the inner cap 21 in correspondence with the spout 4. A spherical check valve 12 is provided between the spout 4 and the outlet 22, and the spherical check valve 12 is biased by a spring 23 toward closing the outlet 22.
2 and the spout 4, a vent passage 24 containing a spherical vent valve 13 is formed in communication with the spout 4, and a vent pipe 25 extends from the vent passage 24 toward the inner bottom of the container 1. It is.

Moreover, as shown in FIG. 6, the cap described in Japanese Utility Model Publication No. 57-37724 has a through hole 31 in the center of the cap body 3 which is screwed onto the neck and neck of the container 1. The inner plug 33, which is biased toward the inside of the container 1 by a spring 32 and has a spout 4 bored in the center, is inserted into the cap body 3.
Further, a support 35 is provided inside the inner stopper 33, which blocks the spout 4 of the inner stopper 33 from the inside and has a ventilation hole 34 formed through the axis thereof. It has a structure in which a spherical vent valve 13 is provided inside which is biased by a spring 36 in the direction of closing the vent hole 34.

[Problem that the invention attempts to solve]

All of these conventional devices have complicated structures, are difficult to assemble, and have a large number of parts, resulting in high costs.

In particular, in the device described in Japanese Utility Model Publication No. 56-51008, the liquid cannot be poured out from the spout 4 unless it passes through the spring 23, so the flow of liquid is obstructed by the spring 23 and is not smooth. .

The present invention was devised in view of these problems, and the technical objective is to provide a liquid dispensing cap that has a simple structure, is easy to assemble, is inexpensive, and allows smooth dispensing.

[Means for solving problems]

The present invention takes the following technical measures to solve the above technical problems.

That is, a cylindrical portion 5 forming a spout 4 is provided on a cap body 3 that is attached to a neck portion 2 of a flexible container 1. A cylinder 7 supported by a plurality of ribs 6 is formed in the cylinder part 5 coaxially with the cylinder part 5, and a cylinder 7 is formed in the upper half of the cylinder 7 so as to be continuous with the ribs 6 and along the axial direction of the cylinder 7. A plurality of protrusions 8 are provided, and an air inflow path 9 is formed between each protrusion 8. moreover,
A valve body 10 is attached to this cylinder 7 to form a liquid pouring cap, and this valve body 10 includes a cylinder 11 that is fitted into the cylinder 7 so as to enclose each protrusion 8, and an upper end of this cylinder 11. The check valve 12 is formed so that the edge becomes thinner and larger in diameter as it goes upward toward the tip, and the tip comes into contact with the inner wall surface of the cylindrical portion 5.
and a vent valve 13 formed on the lower edge of the cylindrical body 11 so that it becomes thinner and larger in diameter as it goes downward toward the tip, and the tip comes into contact with the outer surface of the lower half of the cylinder 7.

A valve body 10 is housed inside the cap body 3, and the number of parts is three in total including the container 1.

[Effect]

When the container 1 is turned upside down and crushed, the liquid in the container 1 pushes open the check valve 12 and is poured out from the spout 4. Then, when the container 1 is placed upright and released, the container 1 returns to its original position with a restoring force that causes the spout 4 to open.
The outside air passes through the air inflow path 9, opens the vent valve 13, and enters the container 1.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

A neck part 2 forming a mouth part of the container is provided at the upper part of a container 1 made of a flexible soft resin.

A cap body 3 is screwed onto this neck and neck part 2, and a cylindrical part 5 forming a spout 4 is provided on this cap body 3, and four ribs 6 are provided in this cylindrical part 5.
A cylinder 7 supported by is provided coaxially with the cylindrical portion 5.

On the outer periphery of the upper half of the cylinder 7, four protrusions 8 are provided that extend in the axial direction of the cylinder 7 and are continuous with the ribs 6. The space between each protrusion 8 serves as an air inflow path 9.

Then, the valve body 1 is arranged so as to include each of the protrusions 8.
0 is attached to the cylinder 7. This valve body 10 is
A cylindrical body 11 is fitted into the cylinder 7 so as to enclose each protrusion 8, and the upper edge of this cylindrical body 11 becomes thinner and larger in diameter as it goes upward toward the tip, and the tip thereof is inside the cylindrical portion 5. The check valve 12 is formed so as to be in contact with a wall surface, and the lower end edge of the cylindrical body 11 has a thinner wall and a larger diameter as it goes downward, and the end thereof is in contact with the outer surface of the lower half of the cylinder 7. It is equipped with a vent valve 13 formed by.

As shown in FIG.
Liquid flows out from the space between them.

The upper edge of the cylindrical portion 5 is closed, and a notch 14 is formed around it. When the spout 4 is opened by cutting out the notch and the container 1 is turned upside down and crushed, the liquid inside the container 1 is turned upside down. The stop valve 12 is pushed open and the liquid is poured out from the spout 4. Further, when the container 1 is stood upright and released, the restoring force of the container 1 causes the container 1 to return to its original position, causing outside air to pass through the air inflow path 9 from the spout 4, open the vent valve 13, and enter the container 1. At this time, the liquid remaining in the spout 4 is returned to the air inflow path 9.
It flows into the container 1 together with the outside air through the air. Therefore, the air inflow path 9 is not clogged with liquid, and the outside air can easily enter, allowing the dispensing operation to be performed smoothly.

[Effect of idea]

According to the present invention, it is only necessary to provide the cylinder 7 in the cylindrical part 5 provided in the cap body 3 and attach the valve body 10 to the cylinder 7, so assembly is extremely easy and the number of parts is only 3. It can be formed at low cost with only one piece.

Further, the valve body 10 formed of a soft material is connected to the spout 4.
Since there is no other intervention, the liquid can be poured out very smoothly, and the outside air can also flow in smoothly, making the pouring operation reliable.
