BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a container 10 with a valve has a body cap 1 which is tightly fitted in an opening 2 of a container body 1.
The variable flow rate cap 10 </ b> A includes a twist cap 21 that is tightly fitted to the main body cap 11, and a cover cap 31 that is tightly fitted to the twist cap 21.

The body cap 11 includes an outer cylinder 13 on the outer peripheral surface of the lower surface of the top surface portion 12 and a valve receiving cylinder 1 on the inner peripheral surface of the lower surface of the top surface portion 12.
4, and the opening edge of the container body 1 is press-fitted between the outer cylinder 13 and the valve receiving cylinder 14. The valve receiving cylinder 14 forms a valve flow path 16 connected to a later-described pouring port 26 of the twist cap 21, and is a valve that is deep on the front side (pouring direction side) and shallow on the back side (anti-pouring direction side). A seat 17 is provided at the lower end portion, and a self-closing valve 18 that closes the valve flow path 16 by swinging by the own weight of the valve body 18A when the valve-equipped container 10 is in the upright state. The self-closing valve 18 can swing to the back side of the valve seat 17 by a hinge 19 in which a pin 19A provided on the uppermost portion when the container 10 is in an upright state is fitted to a concave support portion 19B of the valve receiving cylinder 14. Be combined. The self-closing valve 18 is provided on the valve seat 17 in the upright state of the container 10.
The valve passage 16 is placed on the edge of the front face of the valve body 16, and when the container 10 is tilted from the upright state, the valve passage 18 is swung by the weight of the valve body 18A to open the valve passage 16.

The twist cap 21 has an outer cylinder 23 on the outer periphery of the lower surface of the top surface portion 22 and an inner cylinder 24 at the center of the lower surface of the top surface portion 22, and the body cap 11 is located between the outer cylinder 23 and the inner cylinder 24. The outer cylinder 13 and the valve receiving cylinder 14 are lightly press-fitted to be rotatable with respect to the outer cylinder 13 and the valve receiving cylinder 14 of the body cap 11. The twist cap 21 has a spout cylinder 25 at the center of the upper surface of the top surface part 22, and forms a spout 26 in which the inner circumference of the inner cylinder 24 and the inner circumference of the spout cylinder 25 are continuous. The twist cap 21 has a thin portion 27 that is continuous with the entire lower end of the inner cylinder 24.
The sealing member 28 is integrally molded via the above, and the pull ring 29 is provided on the upper surface of the sealing member 28.

The twist cap 21 is provided with a valve body stopper 30A constituting a valve body opening angle regulation adjusting means 30 projectingly provided at an appropriate position on the inner periphery of the lower end portion of the inner cylinder 24 facing the self-closing valve 18.

In the stopper 30A, the rotation angle of the twist cap 21 with respect to the body cap 11 is the original position (0 degree).
When the container 10 is tilted, the opening angle of the valve body 18A is increased without colliding with the valve body 18A which is rocked by its own weight by tilting the container 10 to increase the pouring flow rate of the contents from the valve flow path 16 and the pouring port 26. The flow rate (Fig. 2).

On the other hand, the stopper 30A collides with the outer edge of the valve body 18A which swings by its own weight when the rotation angle of the twist cap 21 is rotated to the twist position (for example, 30 degrees) to open the valve body 18A. The angle is made small, and the flow rate of pouring from the valve channel 16 and the pouring port 26 is made small (FIG. 3).

That is, in the valve body opening angle regulating means 30 of the variable flow rate cap 10A, the self-closing valve 18 is the stopper 30A.
The opening angle of the valve body 18A, which is regulated by colliding with, is adjusted in two steps by the rotation angle of the twist cap 21 with respect to the main body cap 11, and the pouring flow rate can be switched between large and small steps. The setting of the rotation angles of the twist cap 21 with respect to the body cap 11 between the original position and the twist position can be visually confirmed by the display provided on the body cap 11 and the twist cap 21.

The twist cap 21 has a top surface portion 22.
The rising tubular portion 22A which rises from the above is provided, and this rising tubular portion 22A is made to function as a liquid reservoir wall for the liquid hanging around the spout barrel 25 and the outer wall.

The cover cap 31 has a hinge 32 on the back side (counter-pouring direction side) of the outer cylinder 23 of the twist cap 21.
And a cover 33 that is integrally connected with each other. The cover cap 31 covers the annular locking portion 34A continuously provided on the outer circumference of the rising tubular portion 22A of the twist cap 21 with the annular locking portion 34B continuously provided on the inner circumference of the cover 33. The closed state of 33 is maintained. The cover cap 31 is
On the front surface of the cover 33, a protrusion 35 for opening which serves as a clue at the time of opening is provided.

The valve-equipped container 10 includes a body cap 11,
Each of the twist cap 21 and the cover cap 31 can be formed of a plastic injection molded body such as PP or PE.

Since the valve-equipped container 10 is equipped with the self-closing valve 18 which is closed by its own weight when it is erected as described above, at the product stage in which the contents are filled, the contents are changed to atmospheric components such as water and oxygen. When it is made of a substance that reacts, for example, edible oil, it prevents its deterioration.

When the valve-equipped container 10 is used, as shown in FIGS. 2 and 3, the cover cap 31 is opened by setting the rotation angle of the twist cap 21 to either the original position or the twist position described above, and the twist cap is opened. After the sealing member 28 of the cap 21 is cut off by using the pull ring 29, the container body 1 is tilted to open the valve body 18A of the self-closing valve 18 at any one of the two opening angles, large and small, as described above. The contents can be discharged from the spout 26.

The valve-equipped container 10 is, as shown in FIG. 1, a valve seat 17 that defines a valve passage 16 of a main body cap 11, and is disposed at a vertically lower part when the container main body 1 is upright, preferably at the lowermost part. A groove-shaped (or hole-shaped) communication portion 40 that communicates with the inside of the container body 1 can be provided at such a position. When the content is, for example, edible oil, the cross-sectional area of the communication part 40 is 5 mm.
² or less is suitable. In addition, the communication part 40 is the self-closing valve 18
It can also be provided on the valve body 18A. When the container body 1 is returned to the upright state after pouring out the contents from the pouring port 26, the liquid adhering to the valve passage 16A can be returned from the communication portion 40 to the inside of the container body 1. Accordingly, it is possible to prevent the liquid from remaining in the valve flow path 16 </ b> A and solidifying to cause a malfunction of the self-closing valve 18.

In the variable flow rate cap 10A of FIG.
The lower end of the inner cylinder 24 of the twist cap 21 is provided with a fall prevention rib 41 for the pin 19A of the self-closing valve 18 fitted to the concave support portion 19B provided on the valve receiving cylinder 14 of the main body cap 11.

Therefore, according to this embodiment, there are the following effects. By adjusting the opening angle of the valve body 18A of the self-closing valve 18 by the opening angle regulating means 30 in two or more stages,
The pouring flow rate can be controlled in two or more steps. At this time, the self-closing valve 18 oscillates over almost the entire diameter of the cap, and a large opening area that is largely opened by the oscillating angle can be secured, and the compact cap 10A allows the pouring flow rate to be in a wide range from small to large. You can control.

Since the twist cap 21 is provided with the valve body stopper 30A constituting the opening angle regulating means 30, the opening angle of the self-closing valve 18 can be easily adjusted by adjusting the rotation angle of the twist cap 21 with respect to the body cap 11. Therefore, the operability of controlling the pouring flow rate can be improved.

Even when the content of the container body 1 is made of a substance that reacts with moisture in the atmosphere, such as edible oil,
The self-closing valve 26 can be set to the spout 1 by simply erecting the container body 1.
7 is closed automatically. Therefore, it is possible to easily and surely prevent the contents from being deteriorated by the user forgetting to close the cap.

The valve-equipped container of the present invention may be a hinge cap or a screw cap as long as it has a self-closing valve by its own weight, and the above is only one embodiment.

The opening angle restricting means of the present invention is not limited to a single stopper, but may be provided with a plurality of stoppers to obtain a pouring flow rate according to the selected stopper.

[0025]

As described above, according to the present invention, the pouring flow rate can be controlled in a wide range from small to large by a compact cap.
