[Structure] A reversing wall portion 4 having a central portion of the top wall 3 projecting upward in the shape of a cone is provided so as to be elastically reversible below the top wall 3, and a pouring cylinder portion 5 and a blockage are provided on the reversing wall portion 4. The plate 6 is provided so as to project, and when the inversion wall portion 4 is inverted downward, the opening end of the pouring tube portion 5 is liquid-tightly closed by the closing plate 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pouring cap.

[0002]

[Prior art] [Problems to be solved by the device]

 As a pouring cap, a top wall that closes the upper end opening of the neck and neck is extended from the upper edge of the peripheral wall fitted to the outer periphery of the neck and neck of the container body, and a pouring tube is erected at the center of the top wall. It is known that a cap main body and a lid body is provided so that the top surface of the main body is openable and closable, and a rod plug is provided from the back surface of the top wall so as to fit and close the pouring cylinder portion.

These can be formed by integral molding of synthetic resin, and despite having a simple structure, a good sealing property can be obtained simply by closing the lid, and the liquid in the container can be poured by simply opening the lid. Although it is a convenient one that can be taken out, the pouring barrel is extremely short because it fits the rod stopper of the lid and is housed inside the lid, so it is extremely short, and a target for pouring is set. There was a difficult drawback.

The present invention solves the above-mentioned drawbacks of the prior art, and makes it easy to pour out the liquid by projecting the pouring tube relatively large, and opening and closing the pouring tube with an extremely simple one-touch operation. It proposes an excellent pouring cap that can be used.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the cap of the present invention is a pouring cap integrally formed entirely of synthetic resin, in which the top wall 3 is extended from the upper end edge of the peripheral wall 2 fitted to the neck and neck of the container body. An inversion wall portion 4 having a central portion of the top wall 3 protruding upward in the shape of a cone is provided so that the inversion wall portion 4 can be elastically inverted downward, and the base end of the inversion wall portion 4 is opened and poured out upward. When the tubular portion 5 is erected and a closing plate 6 is projected at a predetermined position of the reversing lower portion opposite to the standing position of the pouring tubular portion 5, when the reversing wall portion 4 is inverted below the top wall 3. The opening of the tip of the spout 5 is closed by a closing plate 6 in a liquid-tight manner.

[0006]

[Action]

 From the state of FIG. 1, for example, when the closing plate 6 is pushed toward the pouring tube portion 5 side, the reversing wall portion 4 elastically reverses below the top wall 3 as shown in FIG. A closing plate 6 press-contacts the upper end opening of the tubular portion 5 to close the opening in a liquid-tight manner.

If, for example, the closing plate 6 is pushed to the side opposite to the above from this state, the reversing wall portion 4 elastically reverses above the top wall 3 to return to the original state, and the liquid is poured out. It will be possible.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of the present invention, in which 1 denotes a spout cap. The cap 1 is integrally formed of a synthetic resin, and a top wall 3 is extended from an upper end edge of a cylindrical peripheral wall 2 to be fitted into the neck and neck of the container body, and an inversion wall portion 4 is provided at a central portion of the top wall 3. It is provided. The reversal wall portion 4 has a conical plate shape projecting above the top wall 3 and is configured to be elastically reversible below the top wall 3. It is configured so as to be easier, and if necessary, the peripheral edge portion may be formed in a thin hinge shape.

Further, a base end portion is opened at the center of the right side of the reversing wall portion 4, and a spouting cylinder portion 5 is erected upward, and a closing plate 6 is erected on the left side. .

In the present embodiment, the spouting tube portion 5 is erected vertically, and the closing plate portion 6 is a rectangular plate shape facing the spouting tube portion 5 and is pouring out at a predetermined center position on the inner side surface. A truncated cone-shaped projection 6a that can be fitted into the upper end opening of the tubular portion 5 is provided so as to project, and a triangular plate-shaped support plate portion 6b is provided at the bottom of the rear surface. When the inversion wall portion 4 is elastically inverted to the lower side of the top wall 3, the injecting tubular portion 5 and the closing plate 6 come into pressure contact with the inner side surface of the closing plate 6 at the upper end opening of the injecting tubular portion 5, and The protrusions 6a are erected at such positions that they fit into the upper end opening of the spout tube portion 5.

In the figure, reference numeral 7 denotes a ridge for engaging with the outer periphery of the neck of the container body, and 8 denotes a fitting cylinder fitted to the upper end of the inner surface of the neck of the container body.

FIG. 3 and FIG. 4 show another embodiment of the present invention. In this embodiment, the pouring tube portion 5 is not vertical but is slightly inclined and protrudes, and accordingly It shows an example in which the closing plate 6 is formed in a plate shape having a V-shape on the side surface.

The inversion wall portion 4 is not limited to the conical plate shape in each of the above-described embodiments, and may be a quadrangular pyramid plate shape or a polygonal pyramid plate shape having a larger number than that.

[0015]

[Effect of device]

 As described above, the container of the present invention has the cap configuration having the relatively long pouring tube portion due to the above-described configuration, and the pouring tube portion can be opened and closed by one-touch operation. It is possible to open and close, and it is easy to set the target for pouring out the liquid and it is convenient to handle.

[0016] Furthermore, if necessary, the spouting cylinder portion can be provided so as to be inclined and projected outward, and in that case, there is an advantage that the liquid can be easily spouted out without largely tilting the container body.

Further, in the state where the reversing wall portion is projected upward and liquid can be poured out, the pouring tube portion and the closing plate are largely projected upward, but when the reversing wall portion is elastically reversed downward, , The spouting tube part and the closing plate fall inward and barely protrude from the top wall so that it does not get in the way.

Further, since it is formed by integral molding of synthetic resin, it has an advantage that it can be manufactured at low cost.
