Description

The present invention relates to a desktop type or portable type liquid container provided with an inner stopper having a liquid passage.

Conventionally, an exterior body that surrounds the inner container, an inner plug that is detachably screwed to the inner center of the upper end of the outer body, and that opens and closes the mouth of the inner container, is provided with a liquid passage in the inner plug body, Provided with a valve body that opens and closes the liquid passage at a location close to the inner container mouth, and a valve body operation member that operates the valve body from the outside of the inner plug, and operates the valve body operation member to open the valve body to open the liquid container body. As a utility model registration No. 2593359 (see Patent Document 1 and FIG. 1), there is a liquid container that allows the liquid in the inner container to flow through the liquid passage toward the spout provided at the front upper end of the exterior body. To do.

Utility Model Registration No. 2593359 (see FIG. 1)

Hereinafter, a conventional liquid container will be described with reference to FIG.
The liquid container of Patent Document 1 is provided with a container main body 1 by an exterior body that surrounds an inner container 3, and an inner plug 2 that is detachably attached to the inner center of the upper end of the container main body 1 and that is screwed near the mouth of the inner container. The inside plug body of the inside plug 2 has a liquid discharge passage 11, a valve body 14 for opening and closing the discharge passage 11 at a location close to the inner container mouth of the discharge passage 11, and a valve operated from above the inside plug Device 13, push button 15 of valve device 13 is pressed, valve body 14 is lowered, discharge passage 11 is opened from the inner container mouth toward discharge port 6, handle 19 is held, and container body 1 Is inclined toward the discharge port 6, the liquid in the inner container 3 can flow out of the discharge port 6 through the discharge passage 11 in the inner plug 2.

However, in such a conventional liquid container, when the body portion of the inner container is thick (it has become thicker to reduce the height), there is a limit even if the mouth is made small, and the mouth diameter is inevitably. Since the inner plug itself becomes larger, the center of the discharge passage is closer to the center of the inner plug, the valve body that does not directly contact the inner container mouth is made smaller, and cost reduction is measured. And it has been measured to make assembly work easier.
However, on the other hand, even if a large dead space is generated between the inner container mouth and the valve body, and the container body is largely inclined and poured out, the liquid is accumulated without flowing out to the front side of the dead space. There was a problem that the liquid inside could not be poured out reliably and smoothly.

In addition, if a detection unit or the like that detects the amount of liquid or the temperature of the container body is hung from the receiving part to which the inner plug of the shoulder of the container body is screwed, the inner container mouth is not circular but slightly protrudes inward. Since the inner plug must be screwed to avoid the part, it is inevitably necessary to make the valve body small, and there is a dead space between the inner container mouth and the valve body (especially the front side) as described above. As a result, there is a problem in that the liquid in the inner container cannot be reliably and smoothly poured out even when the container body is greatly inclined.

The present invention includes a vacuum double bottle container 2 that also serves as an exterior body, a shoulder member 3 attached to the outside of the upper end of the container 2 and provided with a spout 6 on the front side, and below the center of the upper end of the shoulder member 3. And a valve plug for opening and closing the liquid passage 33 at a location close to the mouth of the container 2. The valve plug is provided with a liquid passage 33 in the inner plug 4. 34 and a valve element operating member 35 for operating the valve element 34 from the outside of the inner plug, and the inner diameter of the liquid injection port 33a of the liquid passage 33 of the inner plug is formed smaller than the inner diameter of the container 2 mouth, In the liquid container 1 in which the operation member 35 is operated, the valve body 34 is opened, the liquid container body is tilted, and the liquid in the container 2 flows through the liquid passage 33 toward the spout 6 of the shoulder member 3. The liquid inlet 33a of the liquid passage 33 of the inner plug 4 inserted into the container 2 mouth is close only to the front of the mouth inner wall. The valve body 34 is provided in a thin and tapered thin plate 34a that is slightly larger than the liquid inlet 33a that closes the elongated and tapered liquid inlet 33a. It is said.

The present invention solves the conventional problems, and it is not necessary to incline the liquid container main body at the time of dispensing the liquid, and it is possible to ensure smoothness without leaving the liquid in the liquid container main body. The present invention provides a liquid container that can be poured into a container.

As shown in FIGS. 2 to 3, the lever 40 that moves the valve body 34 is pivotally supported in the front of the inner plug 4, protrudes from the rear of the upper lid 32, and puts a finger on the protrusion. It is operating.

First, in order to attach the inner plug 4 to the container 2, the inner plug 4 is screwed clockwise from the right-right direction in the receiving portion 13 toward the spout 6 from the rear side so that the inner plug 4 is rotated around the container 2. Can be attached to the upper peripheral wall portion 13a.

Next, the operation will be described. A hand is put on the handle 3, and the liquid container 1 is tilted in a depressed state by touching the protruding portion of the lever 40 with the thumb of the hand. In this state, the valve element 34 descends against the spring spring 38, and a gap is formed between the thin plate member 34a of the valve element and the liquid inlet 33a of the liquid passage 33, and the liquid in the container 2 flows from this gap. It flows out to the liquid passage 33. When the thumb of the hand on the lever 40 is removed, the thin plate member 34a of the valve body is lifted by the spring spring 38, and the gap between the thin plate member 34a of the valve member and the liquid inlet 33a of the liquid passage 33 is closed. The outflow to the liquid passage 33 is prevented.
