BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container provided with a liquid amount display device for displaying the liquid amount in an inner container to the outside.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional liquid container with a liquid amount display device. In the liquid container shown in FIG. 4, the liquid volume display device 108 visually checks the height of the liquid level in the liquid volume display tube 181 communicating with the inner container 112 through a vertically long observation window 182 formed in the outer case 111. Inner container 1
It is possible to know the amount of liquid in 12.
Further, in this known example, the observation window 182 has a considerable angular range (for example, an angle of 6) in the horizontal rotation direction from the position of the spout 194.
It is provided at a position displaced by 0 to 80 °). still,
In this type of liquid level display device 108, the liquid level display tube 1
A display plate is provided on the rear side of 81, and the liquid volume display tube 18
Since the convex lens action works on the liquid inflow portion of No. 1 and the pattern of the display plate is enlarged and displayed, the pattern of the display plate can be seen to change at the height of the liquid level in the liquid volume display tube 181. Become.

By the way, in the conventional liquid container shown in FIG. 4, the peep window 182 of the liquid amount display device is not formed to a very high position, and the liquid amount in the inner container 112 is kept to some extent (peep window). Until the height decreases to the height of the upper end 182a of 182), the liquid always flows into the liquid amount display tube 181 within the range that can be seen from the sight window 182. in this way,
When the liquid flows into the entire range of the liquid volume display tube 181 that can be seen through the peep window 182, the convex lens action is uniformly exerted on the entire length portion of the liquid volume display tube 181 that is seen through the peep window 182, and Although the pattern is enlarged, it appears evenly.

[0004]

However, in the conventional liquid container shown in FIG. 4, since the viewing window 182 is located at a position considerably separated from the position of the spout 194 in the horizontal rotation direction, the liquid pouring position. From the (filling port 194 portion), the viewing window 1
Since the height of the liquid level cannot be confirmed through 82, it is necessary to change the posture (change the viewing position) to see the liquid level in the liquid volume display tube 181 at the time of pouring the liquid. The work was troublesome.

Further, in the liquid volume display device used in the liquid container shown in FIG. 4, the upper limit height of the liquid volume display tube 181 seen through the observation window 182 is considerably lower than the full liquid height in the inner container 112. Even if the liquid level in the inner container 112 changes from the full state to the maximum height position of the sighting window 182 (height of reference numeral 182a), the change in the liquid level from the sighting window 182 occurs. Cannot be confirmed. That is, the inner container 1
When the liquid level in 12 is higher than the height of the upper end 182a of the observation window 182, there is a problem that the accurate liquid amount in the inner container 112 cannot be confirmed from the observation window 182.

Further, in the state where the liquid is flowing up to the upper limit height of the liquid amount display tube 181, which can be seen from the sight window 182,
Although the pattern of the display plate is enlarged and displayed due to the convex lens action of the liquid inflow portion, the display of the liquid amount display tube 181 portion appears uniformly in the range that can be seen from the observation window 182. There was a problem that it was difficult to identify whether or not it was flowing.

In view of the above-mentioned problems of the conventional liquid container, the present invention makes it easy to see the height of the liquid level in the liquid volume display pipe at the time of pouring the liquid and protects the upper end of the inner container. The protection member can be effectively used as a mark showing the maximum liquid injection height into the inner container, and the amount of liquid contained in the inner container can be set over almost the entire range from the maximum liquid level to the minimum liquid level. It is an object of the present invention to provide a liquid container that can be externally displayed.

DISCLOSURE OF THE INVENTION The present invention has a series of liquid discharge passages for discharging a liquid in an inner container provided in a liquid container body, and displays a liquid amount communicating with the inner container. In a liquid container equipped with a liquid amount display device, which allows the height of the liquid level in the tube to be viewed through a peep window provided in the liquid container body,
At the opening edge of the inner container, a cover body that covers the opening edge by being exposed to a predetermined depth in the upper opening of the inner container,
Further, the peep window of the liquid quantity display device is provided directly below the spout pipe cover that covers the spout pipe of the liquid spout passage, and the peep window is set from the height of the lowest liquid level in the lower inner container. It is characterized in that it is formed over almost the entire height range up to the height of the protruding lower end of the upper cover body.

[0009]

In the liquid container of the present invention, since the opening edge of the inner container is covered with the cover body, the external edge article does not collide with the opening edge portion of the inner container.

Further, since the lower end of the cover is inserted to a predetermined depth inside the upper opening of the inner container, the lower end of the cover can be seen at a position lower by a predetermined height than the edge of the liquid supply port, and the cover is The lower edge of the body can be used as a mark indicating the maximum liquid injection height when the liquid is injected into the inner container. That is, when there is no mark that indicates the maximum liquid injection height during the liquid injection work into the inner container, it is difficult to see the inside of the inner container, so it is possible to inject the liquid until it overflows from the edge of the liquid supply port. However, when the lower end edge of the cover body is visible from the liquid supply port, it is possible to visually recognize the liquid from the outside when the liquid is injected up to the lower end edge, and thereby draw attention to the supercharged liquid. it can.

By the way, the liquid pouring operation is generally performed from the pouring side because the liquid receiving container is located below the pouring port. However, the peep window of the liquid quantity display device covers the pouring pipe. Since it is provided just below the mouth tube cover, the operator of the liquid comes to face the viewing window during the liquid pouring operation, and the liquid level in the liquid level display tube is raised without changing the posture. You can check that.

Further, the liquid amount in the inner container is displayed by the height of the liquid level in the liquid amount display tube over the entire range from the full liquid level to the minimum liquid level. Since the viewing window of the volume indicator is formed over almost the entire height range from the height of the lowest liquid level in the inner container to the height of the lower end of the cover body (which is the height of the full liquid level), the inner container It is possible to see almost the entire range of the height of the liquid level that displaces in the liquid volume display tube according to the liquid volume in the viewing window. Can be known over almost the entire range.

[0013]

The liquid container of the present invention has the following effects. That is, since the inner surface of the upper opening of the inner container is covered with the cover body, the upper end portion of the inner container can be protected.
Further, since the lower end of the cover body is inserted to a slight depth inside the upper opening of the inner container, the lower end edge of the cover body can be effectively used as a mark of the maximum injection liquid level when the liquid is supplied into the inner container. Furthermore, since the viewing window of the liquid volume display device is provided directly below the spout pipe cover, the liquid level in the liquid volume display pipe can be seen at the liquid pouring work position, and the liquid volume can be checked when pouring the liquid. Work becomes easy. Further, since it is formed over almost the entire height range from the height of the lowest liquid level in the inner container to the height of the lower end of the cover body (which is the height of the full liquid level),
The amount of liquid in the inner container can be clearly known over almost the entire range from the full liquid level to the minimum liquid level.
