DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, 1
Is a liquid spout. The pouring plug is composed of a plug main body and an auxiliary lid, and the plug main body 2 hangs a peripheral wall 4 for fitting the neck portion of the container body from the outer periphery of the top wall 3 and a central part of the top wall is depressed via a hanging cylinder 5. The breaking line 6 is provided around the outer peripheral portion of the top wall portion surrounded by the hanging cylinder, and the top wall portion surrounded by the line serves as the removing plate portion 7, and the connecting rod 8 is erected from the rear portion of the plate portion. Then, a pull ring 9 is horizontally provided on the upper end of the rod. Further, except for the rear side of the stopper body, the hanging cylinder portion is extended upward and outward to form a liquid pouring portion 10, and there is a small gap between the outer peripheral portion of the top wall and the outer edge of the top wall. The fitting short cylinder 11 is erected, and the hanging cylinder 5
An elastic tube 12 is hung from the top wall 3 with a small gap between the and. Furthermore, a stopper 13 is hung from both left and right portions of the top wall portion which is inside the top wall portion surrounded by the hanging cylinder and which is rearward and outward of the removing plate portion 7.

Reference numeral 21 denotes an auxiliary lid that hangs a peripheral wall 23 from the outer periphery of the top plate 22. The outer peripheral edge of the rear lower end of the peripheral wall is attached to the upper end of the rear peripheral wall of the main body of the stopper via a hinge 24, and the lower inner surface of the peripheral wall of the auxiliary lid is attached. It is removably fitted to the outer surface of the short cylinder 11.

The plug body and the auxiliary lid are integrally formed of a synthetic resin material.

Reference numeral 31 denotes a holder which stands up the peripheral wall 33 from the outer periphery of the bottom plate 32. In the illustrated example, the lower surface of the peripheral wall 33 is an inclined surface having a lower front portion and a higher rear portion, and the lower surface is closed by the bottom plate 32. The upper part of the peripheral wall 33 is fitted between the hanging cylinder 5 and the elastic cylinder 12 of the plug main body, and the engaging projection 34 is provided around the outer surface of the upper end of the peripheral wall. As shown in FIG. 2, a valve hole 35 is formed in the bottom plate 32 so as to be slightly eccentric to the front, and a locking projection 36 is provided around the upper edge of the peripheral edge of the valve hole. Further, bearings 37, 37 having the above-mentioned stoppers 13, 13 positioned in the upper end portion and having an opened upper surface are attached to the upper surfaces on the left and right sides of the rear portion of the bottom plate. These two bearings have different lengths in the left-right direction as shown in FIG.
A small groove 38 for recovering the residual liquid in the holder is bored in the front part of the locking projection 36, and the lower part of the front part of the peripheral wall is a downwardly rearwardly inclined wall, and a projection for alignment on the outer surface of the inclined wall. 39 are attached.

Reference numeral 41 denotes a valve element which has a shaft 42 into which the left and right ends having different lengths are rotatably fitted into the bearings 37, 37, and the valve hole is forwardly provided from a shaft portion between the both ends. A valve plate 43 that closes the valve 35 is projected, and on the lower surface of the valve plate, there is provided a protrusion 44 that is placed on the upper surface of the locking protrusion 36 described above. Stoppers 13 and 13 lower ends are located on both ends of the shaft fitted in the bearing to prevent the shaft 42 from being pulled out upward.

Reference numeral 51 denotes a mouth / neck portion standing upright from the body portion of the container body, and an upper portion thereof projects a flange-shaped tubular portion inwardly upward from an upper end of the thin first standing tubular portion 52, and a second portion from an inner end of the tubular portion. Standing tube
53, the upper end of the tubular portion projects outwardly upward from the flange-shaped tubular portion, and the third upright tubular portion 54 is erected from the upper end of the tubular portion.

The peripheral wall 4 of the plug body described above is fitted to the outer surface of the third upright tube portion 54, and the elastic tube 12 is fitted to the inner surface of the second upright tube portion 53. The outer diameter of the elastic tube 12 is formed to be larger than the inner diameter of the second upright tube portion 53.
The lower part of the elastic cylinder is pushed inward by forcibly fitting it to the inner surface of 53, and is pressed against the outer surface of the holder peripheral wall 33 to prevent the holder from being pulled out.

After the liquid is filled in the container body, the container body is transported with the above-mentioned stopper with the holder in a state where the mouth portion of the container body is sealed. In use, the auxiliary lid 21 is opened as shown in FIG. The removal plate portion 7 is removed by pulling up, and the liquid outflow hole 14 is formed by the removal trace. If the upper part of the container body is tilted forward from this state, the valve body 41 opens the liquid outflow hole 14 by the weight of itself around the shaft 42 or the liquid in the container presses the valve plate 43, and the inside of the liquid pouring part 10 is opened. It is poured out on the street. After the liquid is poured out, if the container body is returned to the upright state, the valve body 41
Again closes the liquid outflow hole 14 by its own weight.

Although some liquid remains in the holder 31, the remaining liquid is collected in the container body through the small groove 38 formed in the front part of the locking projection on the peripheral edge of the valve hole 35.

The above-mentioned members are integrally formed of synthetic resin material.

[0020]

The present invention has the above-described structure, and by forming as described in claim 1, the valve body 41 automatically opens and closes the liquid outflow hole 14 every time the liquid in the container is poured out. ,
Therefore, there is no risk of forgetting to close the lid and opening the liquid outflow hole 14 as in the case of opening and closing the lid only with the auxiliary lid. Therefore, dust and the like do not enter the container body, and the replacement of the air inside the container with the outside air is reduced, and the oxidation of the liquid inside the container can be prevented.

According to the second aspect, it is possible to surely and easily attach the holder to the stopper.

According to the third aspect, the valve body 41 can be pivotally attached to the holder.

According to claim 4, the liquid remaining in the holder after the liquid is poured is collected in the front part of the lower end of the holder,
Moreover, the residual liquid can be collected into the container body through the small groove 38,
Further, for example, if the liquid in the container has a high viscosity, the small groove can be closed by the slightly viscous liquid left on the inner surface of the lower end of the front part of the holder, and the airtightness in the container can be improved.

According to the fifth aspect, the holder 31
The valve body 41 is installed inside out against the
The valve plate 43 does not become incompletely sealed with respect to the valve plate 14, and the valve body 41 can always be mounted accurately.
