2. Description of the Related Art Japanese Patent Application Laid-Open No. Sho 62-159352 discloses a cap of the above-mentioned type, which was filed by the present applicant. The cap is formed by forming a recessed portion having an inverted trapezoidal vertical cross-section with the upper surface and the front end surface opened, from the rear portion of the upper surface of the cap top wall to the upper portion of the front surface of the peripheral wall, and gradually deeper toward the front end. Contrary to the recess, a trapezoidal long lid with the bottom side removed is used.The bottom edges of the left and right side plates of the long lid and the left and right upper edges of the recess are used. The left and right side edges of the plate are covered by connecting them through thin hinges, respectively, and the bottom plate of the recess is provided with an outflow hole to form a nozzle with the recess and the long lid. When the upper plate is pushed down, the left and right side plates of the long lid elastically reverse so that the lower surface of the upper plate of the long lid seals the outflow hole. It is designed to open.

[0003]

The cap is for elastically deforming the left and right side plates of the long lid, and the left and right side plates have a triangular shape whose upper and lower side edges are longer than the front edge. The elastic deformation for the elastic reversal at the time of pushing down and pulling up the upper plate is mainly performed at the front part of the side plate, so that the elastically deformed portion tends to be small, and especially when the cap is miniaturized, the elastic reversal is performed. There was a drawback that it was difficult to make it happen. Also, since the nozzle is open at only one end,
There has been an inconvenience in that it is necessary to re-hold the container with the cap so that the opening is located in a direction in which the hand is easily tilted during the outflow operation of the stored items.

According to the present invention, the cross-sectional shape of the nozzle is the same in the front and rear, and both the front and rear ends of the nozzle are opened to eliminate the above-mentioned defects.

[0005]

A peripheral wall 1 for fitting a container mouth neck portion is hung from an outer periphery of a top wall 2, and a diameter portion of the top wall 2 at an intermediate portion in the left-right direction is raised in an inverted box shape to form the raised portion. Outflow holes 5 are formed in a part of the upper surface plate 4 of No. 3, and elastic side plates 7, 7 of substantially the same width are slanted outward from the left and right side edges of the upper surface plate via the first thin hinges 6, 6. And the lower edges of both left and right sides of the elastic top plate 8 formed in a substantially arch-shaped cross section are connected to the upper edges of both elastic side plates via the second thin hinges 9, 9.
The outflow holes 5 are formed so that the lower surface of the elastic top plate 8 can be sealed by displacing the elastic side plates 7 and 7 so as to project downward from the first thin hinges 6 and 6.

[0006]

In the state shown in FIG. 1, the outflow hole 5 is open, and when the elastic top plate 8 is forcibly pushed down from that state as shown in FIG. 2, the elastic side plates 7, 7 elastically reverse and the first paddle hinge. 6,6
It is rotated around the center and is displaced outward and downward. At this time, the elastic top plate 8
The lower surface of the seals the outflow hole 5. By pulling the elastic top plate 8 upward from this state, the elastic side plates 7 and 7 are again moved to the first position.
The thin hinges 6 and 6 are elastically reversed to return to the outlet hole opening state of FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the fluid pouring cap according to the present invention, a peripheral wall 1 for screwing a neck of a container body is suspended from an outer periphery of a top wall 2. The diameter portion of the top wall in the middle in the left-right direction is raised in an inverted box shape, and an outflow hole 5 is formed in the central portion of the upper plate 4 of the raised portion 3. The upper plate surface 4 may be projected outward in the front-rear direction of the peripheral wall as shown. Further, elastic side plates 7 and 7 project obliquely outward from the left and right edges of the upper plate through the first thin hinges 6 and 6, and the cross sections are formed in a vaulted shape to the upper edge of both elastic side plates. The left and right lower end edges of the elastic top plate 8 are attached to the second thin hinges 9,
Connect via 9.

The upper surface plate 4, elastic side plates 7, 7 and elastic top plate 8 of the raised portion form a nozzle 10 having front and rear end surface openings. As shown in FIG. 2, when the elastic top plate 8 is pushed down, the nozzle is displaceable so that the elastic side plates 7 and 7 are elastically reversed about the first bookkeeping hinges 6 and 6 and protrude outward downward. The lower surface of the elastic top plate 8 is provided so as to seal the outflow hole 5.
As shown in FIG. 2, the elastic top plate 8 is preferably provided such that the outer edges 8a, 8a at the lower ends on the left and right sides thereof project outward from the second thin hinges 9, 9 when the outflow hole 5 is closed. By doing so, it is possible to put a finger on the outer edge portions 8a, 8a, pull up the elastic top plate 8, and open the outflow hole 5 as shown in FIG. However, the elastic top plate need not always be formed in this manner. For example, a finger may be hung on the front and rear ends of the upper plate portion of the elastic top plate and pulled up. The elastic top plate 8 may be pulled up. In addition, the said cap can be integrally molded with a synthetic resin agent.

[0009]

The present invention is configured as described above, and the elastic side plate 7 is slanted upward from the left and right edges of the upper plate 4 of the raised portion rising from the top wall 2 through the first thin hinges 6 and 6. , 7 are projected and connected to the upper end edges of both elastic side plates by connecting the left and right lower end edges of the elastic top plate 8 having a substantially arch-shaped cross section through the second thin hinges 9, 9, that is, the upper plate 4 and the elastic plate. Side plate 7,
Since the nozzle 10 is formed by the elastic top plate 7 and the elastic top plate 8, the nozzle is opened at both front and rear ends. The fluid can be poured out, thus eliminating the inconvenience of having to re-hold the container in order to redirect the nozzle opening of the capped container. Further, since the nozzle is open at both ends and has elastic side plates 7, 7 having substantially the same width from the front end to the rear end of the nozzle, the elastic side plates are also elastically deformed at any position between the front and rear, and therefore, as described above. The elastic reversal does not become difficult as in the conventional example. Further, both ends of the nozzle can be located on the outer peripheral side of the top wall 2, which is convenient for pouring the fluid.
