Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a liquid heat-insulating container equipped with a lid body incorporating an air pressurizing device.

[Prior art]

Conventionally, this type of liquid heat insulating container has been constructed as shown in FIG. In other words, the conventional liquid heat insulating container has a main body 1 with a bottomed cylindrical container 2 inside.
and a lid body 3 incorporating a pressurizing device 5 for feeding pressurized air to the container 2 using a bellows 4.
The lid body 3 includes a push plate 8 disposed in an opening formed in the center of the upper plate 13, and the push plate 8 is supported in contact with the upper end of the bellows 4 so as to be movable up and down. Therefore, the inner wall surface of the central opening of the lid body 3 functions as a guide wall 10 for the push plate 8.
Note that the reference numeral 6 indicates a liquid flow path, and the reference numeral 7 indicates a spout at the tip of the liquid flow path.

In such a conventional liquid heat-insulating container, when dispensing the liquid stored in the container 2, the press plate 8 provided on the lid body 3 is pushed by hand to operate the pressurizing device.
The air inside the bellows 4 is pressurized and sent to the container 2,
Pour out the liquid from the spout 7 through the liquid flow path 6,
Apply liquid with a spoon, etc. Note that the bellows 4
Since the spring 9 is biased in the direction of expanding the bellows 4 and pushing back the push plate 8, when the push plate 8 is released, the push plate 8 is pushed back to its original position.

However, the movable distance of the push plate 8 is indicated by the l dimension in the figure, and as described later, the flange-shaped portion 8a of the push plate 8
and the restraining plate 11 of the guide wall 10,
It is good when receiving liquid with a large tip, but when receiving liquid with a small tip or when only a small amount of liquid is desired, pressing the push plate 8 by l will cause the liquid to come out forcefully, causing the liquid to spill or overflow. Ta. Therefore, in such cases, the liquid was dispensed while being careful not to push it all the way to 1.

[Summary of the idea]

This invention was made in order to eliminate the drawbacks of the above-mentioned devices, and by making it possible to set the movable distance of the push plate in multiple stages, it is possible to pour out liquid without spilling or overflowing due to pushing too much. The purpose is to provide a liquid heat insulating container that can

[Example of idea]

Hereinafter, the liquid heat insulating container of the present invention will be described in more detail with reference to preferred embodiments shown in the accompanying drawings.

2 to 4 show a liquid heat-insulating container according to an embodiment of the present invention. In FIGS. 2 to 4 showing this embodiment, the same or corresponding parts as those of the conventional liquid heat insulating container shown in FIG. 1 are given the same reference numerals, and the explanation thereof will be omitted.

The liquid heat-insulating container of the above embodiment has an upper plate 1 of a lid body 3.
3 and a recess 16 provided in the lower plate 15 of the lid 3, the operating part 12 is rotatable. A regulating plate 18 is integrally formed on this operating portion so as to protrude laterally.

On the other hand, a notch hole 19 is formed in the guide wall 10 of the lid body 3 in the same plane as the plane in which the regulating plate 18 provided on the operating section 12 is located. This notch hole 19 is inserted into the regulating plate 1 when the operating section 12 is rotated.
8 is formed at a corresponding position such that it can protrude into the movement path of the push plate 8, that is, into the central opening of the lid. The peripheral edge of the push plate 8 projects like a flange, and a rib 8b is provided at the lower part of the flange-like portion 8a. This rib 8b is formed so as to be located above the regulation plate 18 when it protrudes from the notch hole 19. Further, a stop plate 11 is integrally formed below the notch hole 19 in the guide wall 10 of the lid body 3 over the entire circumference and extends toward the central opening side. The locking edge 8c is engaged with the locking edge 8c extending laterally outward to prevent the push plate 8 from moving upward from a predetermined position. In this stop plate 11, when the push plate 8 is pushed and moves downward, a groove 11b is formed at a corresponding position on the movement path of the rib 8b provided at the lower part of the flange-shaped portion 8a of the push plate 8. It is made so that it can pass through the stop plate 11. Therefore, in a normal state, the push plate 8 can move downward by a distance l such that the flange-shaped portion 8a of the push plate 8 abuts against the stop plate 11, as in the conventional case.

According to the liquid heat-insulating container of this embodiment, when you want to dispense only a small amount of liquid, by rotating the upper knob 17 of the operating section 12 by 180 degrees, the regulating plate 18
protrudes from the notch hole 19 of the guide wall 10. As a result, when the push plate 8 is pushed, the rib 8b provided at the lower part of the flange-like portion 8a collides with the restriction plate 18, thereby preventing further downward movement of the push plate 8. Therefore, the movable distance of the push plate 8 in this case is only m in the figure.

However, if the knob 17 is rotated and returned to its original position during normal use, when the push plate 8 descends, the rib 8b will not collide with the regulation plate and the stop plate 1
Since the groove 11b provided in 1 is also passed through, the flange-like portion 8a can move the same distance l as in the conventional case where it comes into contact with the stop plate 11, as described above.

In the above embodiment, the operating section 12 is rotated to restrict the lowering of the rib 8b. However, the regulating plate 18 of the operating section 12 is fixed, and when the push plate 8 is provided with a knob and rotated, the rib 8b acts as a regulating plate. It is also possible to come above the push plate 18 and restrict the downward movement of the push plate 8.

[Effect of idea]

As explained above, according to the present invention, the movable distance of the push plate can be regulated in multiple stages, so it is safe to prevent over-pouring and spillage.
