Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a stopper for a stationary liquid container used particularly outdoors.

(Prior Art) Conventionally, this type of liquid container stopper has a valve seat provided in an outflow path communicating with the bottom of the container body, and opens and closes the outflow path by moving a valve body located opposite to the valve seat back and forth. It's becoming like that. The means for advancing and retracting the valve body includes a screw type, a push button type, a lever type, and the like.

(Problem to be solved by the invention) However, in any of the stoppers, the spout that opens at the end of the outflow path is exposed to the outside air.
There was a problem that it was unsanitary to use outdoors due to the adhesion of dust and the ingress of insects.

The present invention was developed in view of the above problems, and an object of the present invention is to provide a stopper for a liquid container equipped with a cover that opens and closes the spout at the same time as the stopper opens and closes.

(Means for Solving the Problem) In order to solve the above problem, the present invention opens and closes the outflow path by moving a valve body facing a valve seat provided in the outflow path communicating with the bottom of the container body back and forth. A stopper for a liquid container is provided with a cover that opens and closes a spout opening at the end of an outflow path in conjunction with the opening and closing operations of a valve body.

(Example) Next, an example of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a liquid container equipped with a stopper according to the present invention, where 1 is a container body, a heat insulating material 5 is provided between an inner container 2 and an outer wall plate 3 or a bottom plate 4, and 6 is a container body. The lid, 7 is a leg, and 8 is a handle. The stopper provided at the lower front of the container body 1 generally consists of a stopper body 9, a stopper case 10, a lever 11, and a cover 12.

As shown in FIGS. 2 and 3, the stopper body 9 is a cylindrical container that stands upright outside the container body 1, and has a communication pipe 13 integrally formed on the side and a spout at the bottom. 14 are provided. The communication pipe 13 is fixed to penetrate through the inner container 2, the heat insulating material 5, and the outer wall plate 3 at the lower part of the container body 1.

That is, the flange 15 is provided on the outer periphery of the communication tube 13, and after inserting the seal packing 16 and the packing holder 17 into the tip protruding into the inner container 2, the nut 18 is screwed to connect the flange 15 and the packing holder 17. By clamping and compressing the container body 1, the stopper body 9 is fixed, and the communication pipe 13 and the inner container 2 are sealed by the seal packing 16.
At this time, a substrate 10a of the plug case 10, which will be described later, is interposed between the flange 15 and the outer wall plate 3, and the plug case 1
0 is clamped and fixed.

A lid 19 is screwed onto the upper end of the stopper main body 9 via a seal packing 20, and the inner container 2 of the container main body 1
A flow path is formed that extends from the bottom of the valve through the communication gap 13 and the plug body 9 to the spout 14.

Further, inside the stopper body 9, a valve body 22 is slidably fitted into a guide pipe 21 vertically provided on the inner surface of the lid body 19, and the upper end of the valve body 22 is connected to the lid body 19.
The lower end thereof is located opposite to the spout 14 . The valve body 22 is biased downward by a spring 24 that is compressively biased and attached to the tube between the flange 23 and the lid body 19 provided near the lower end.
A valve seat 26 formed above the spout 14 is pressed through a seal gasket 25 attached to the lower surface of the flange 23 to normally close the outflow path. Note that between the guide pipe 21 and the valve body 22, the valve body 22
It is designed to be sealed by a seal packing 27 attached to the outer periphery of the.

The stopper case 10 is box-shaped with the front, part of the top, and part of the bottom missing, and as described above, the substrate 10a serving as the back is fixed to the container body 1, and the opposing sides 10b and 10c are It is provided so as to sandwich the plug body 9.

The lever 11 is bent into a shape, and has four ribs 11a, 11b, 11 extending from the bent portion to the upper tip.
c, 11d, and the ridges 11b, 11c and the lid body 19 are located inward from the top tip.
The more protruding tip of the valve body 22 is joined with a pin 28. At this time, a predetermined space was left between the tips of the ribs 11b and 11c and the lid 19. Further, the cover 12 is provided integrally with the lever 11 slightly above the lower end of the lever 11 so as to form a substantially U-shape together with the lever 11. The lever 11 and cover 12 cover the front, upper and lower surfaces of the plug case 10.

In the liquid container stopper constructed as described above, when the lower end of the lever 11 is pulled up diagonally upward and rotated, the lever 1
1 rotates around the pin 28 and its rib 11
The tips of b and 11c abut against the lid 19. At this time, the cover 12 moves diagonally forward together with the lever 11, so that the spout 14 appears.

Then, when the lower end of the lever 11 is further pulled up, the lever 1
The tips of the ribs 11b and 11c of No. 1 serve as moving fulcrums, and the lever action moves the valve body 22 through the pin 28.
is pulled upward. At this time, since the space between the seal packing 25 and the valve seat 26 opens, the inside of the inner container 2 and the spout 14 communicate with each other, and the liquid inside the inner container 2 flows out from the spout 14. Here, since the cover 12 covering the spout 14 has already moved obliquely upward together with the lever 11, the flow of liquid from the spout 14 is not blocked by the cover 12.

Next, when the force pushing up the lever 11 is released, the valve body is pushed down by the spring 24, so
At the same time that the lever 11 returns to the state indicated by the two-dot chain line A in FIG. 2, the seal packing 25 presses the valve seat 26, so that the outflow of liquid from the spout 14 is stopped. If the lever 11 is further pushed down from this state, the cover 12 will cover and close the spout 14.

In this embodiment, the pin joint that serves as the fulcrum of the lever 11 is provided above, but it may be provided below or on the side. In this case, it is necessary to appropriately change the outflow path so that the spout 14 faces downward, and also to change the attachment position of the cover 12 to the lever 11.

FIG. 4 shows a second embodiment of the stopper for a liquid container according to the present invention, and unlike the first embodiment, a lever 31 that slides vertically to raise and lower the valve body 22 is used to open and close the spout 14. A cover 32 is provided.

That is, the lever 31 has its ribs 31b, 3
1c and the valve body 22 are joined by a pin 28, and are formed to be slidable in the vertical direction with respect to the side plates 10b, 10c of the stopper case 10. Here, the pin holes 3 provided in the ribs 31b and 31c of the lever 31
3 is an elongated hole, and the valve body 22 cannot be pulled up unless the lever 31 is slid to a predetermined height.

The cover 32 has a pin 34 at the bottom of the lever 31.
The spout 14 is pivotably joined to the spout 14 by a torsion spring 35 attached to a pin 34, and is biased in a direction to cover and close the spout 14.
The side plates 10b and 10c of the stopper case 10 are provided with protrusions 36 that engage with the upper surface of the cover 32. Further, a lower knob 37 is provided on the front surface of the lever 31, and a side plate 10 of the stopper case 10 is further provided with a lower knob 37.
An upper knob 38 is placed horizontally between b and 10c, and the lower knob 38 is placed between the lower knob 37 and the upper knob 38.
By pulling up the lever 7, the lever 31 is slid upward.

In the stopper constructed as described above, when the fingers are placed on the upper knob 38 and the lower knob 37 at the same time and the lower knob 37 is pulled up, the lever 31 slides upward as shown by the two-dot chain line C in FIG. At this time, lever 31
Since the pin hole 33 is an elongated hole, the valve body 22
is not pulled up, but the protrusion 36 acts to push down the cover 32, so the cover 32 opens as shown by the two-dot chain line D in the figure. Further lower knob 3
When the lever 7 is pulled up, the lever 31 pulls up the valve body 22 via the pin 28, so that liquid flows out from the spout 14 as in the previous embodiment.

Also, if you let go of the lower knob 37, the spring 24
As a result of pulling down the valve body 22 (see FIG. 2), the lever 31 is pulled down to the position indicated by the two-dot chain line C in the figure. Then, when the lever 31 descends due to its own weight, the cover 32 springs up due to the restoring force of the torsion spring 35, thereby closing the spout 14.

(Effects of the invention) As is clear from the above explanation, according to the invention, a cover is provided that opens and closes the spout opening at the end of the outflow path in conjunction with the opening and closing operations of the valve body. During closure, the spout is always closed with a cover, preventing dust from entering, making it sanitary. Further, since the cover of the spout opens and closes in conjunction with the opening and closing operations of the valve body, there is no need to provide a separate cover, which has the advantage of being extremely simple.
