Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a liquid dispensing cap.

"Problems to be solved by conventional techniques and devices" As a container for storing a liquid, a container body in which a mouth and neck is erected, and a top wall extending from an upper edge of a peripheral wall detachably fitted to the outer periphery of the mouth and neck are extended. It is generally known that the cap and the cap are installed, but these are troublesome to handle because the cap is attached and detached when pouring out the content liquid. It is also known to have a spout cap in which a spout nozzle having an upper surface closed from an outer peripheral edge of a through hole formed in a top wall is provided upright. These are convenient because they are used by cutting the tip of the nozzle at the time of use, and there is no need to attach or detach a cap when pouring, but the nozzle that is open at one end does not have a lid, so dust etc. There is a risk of entering the body.

The present invention provides a dispensing cap that overcomes the above-mentioned disadvantages of the prior art.

"Means for Solving the Problem" The top wall 3 extending from the upper edge of the peripheral wall 2 is recessed downward to form a reversible top wall portion 4 which is elastically reversible.
Is a first rectangular portion 5 which descends rearward from the front portion of the top wall 3 via a first hinge 9, and a front side of the first rectangular portion 5 is connected to the rear side of the first rectangular portion 5 via a second hinge 10. In addition, a second rectangular portion 6 whose rear side rises rearward and is connected to the top wall 3 via a third hinge 11, and the right front apex a of the first rectangular portion 5 on the top wall 3
An arc-shaped fourth hinge 12 extending from the right rear vertex b of the second rectangular portion 6 to the fifth hinge 13 between the right front and rear vertices of the first rectangular portion and a sixth hinge between the right front and rear vertices of the second rectangular portion. A spherical right curved surface portion 7 surrounded by 14 and a left-right apex e of the second rectangular portion 6 from the left front vertex d of the first rectangular portion 5 while forming a left-right symmetry with the curved surface portion 7. Spherical curved left curved surface portion surrounded by an arc-shaped seventh hinge 15 and an eighth hinge 16 between the left and right apexes of the first rectangular portion and a ninth hinge 17 between the left and right apexes of the second rectangular portion 8, a cylindrical nozzle 18 is vertically provided above the upper surface of the first rectangular portion 5 and a through hole is formed in the first rectangular portion 5 on the lower surface of the nozzle 18 to form a spout 19. That is, the closing plate 20 is hung from the lower surface of the front end of the second rectangular portion 6, and when the nozzle 18 is tilted forward, the inverted top wall portion 4 is The closure plate 20 is turned upside down to project above the top wall 3, and the closing plate 20 closes the spout 19.

"Function" It is used by fitting it to the neck of the container that holds the liquid. When not in use, the nozzle 18 is tilted forward as shown in FIGS. 3 and 4, and when the nozzle 18 is erected rearward from this state, the inversion top wall portion 4 elastically inverts and the bottom wall 3 downward. Then, the closing plate 20 that has closed the spout 19 and opens the spout 19 as shown in FIG. 2 allows the liquid to be spouted from the nozzle 18. After use, if the nozzle 18 is tilted forward from the state shown in FIGS. 1 and 2, the inverted top wall portion 14 elastically reverses and protrudes above the top wall 13, and accordingly, the closing plate.
20 moves so as to incline forward and closes the spout 19.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the present invention, in which 1 is a liquid pouring cap. The cap 1 has a top wall 3 extending from the upper edge of a cylindrical peripheral wall 2 and recessing the top wall 3 downward to form a reversible top wall portion 4 capable of elastic reversal. The inverted top wall portion 4 includes a first rectangular portion 5 and a second rectangular portion 6
And a right curved surface portion 7 and a left curved surface portion 8. The first rectangular portion 5 has a rectangular shape that descends rearward from the front portion of the top wall 3 via the first hinge 9, and the front side of the second rectangular portion 6 is provided on the rear side of the first rectangular portion 5. The second hinges 10 are connected in series. In addition, the second rectangular portion 6 rises rearward, and the rear side is the third side.
It is connected to the top wall 3 via a hinge 11. Right curved surface part 7
Is an arcuate fourth hinge 12 extending from the right front vertex a of the first rectangular portion 5 to the right rear vertex b of the second rectangular portion 6 on the top wall 3,
The fifth portion between the right front vertex a and the right rear vertex c of the first rectangular portion 5
It has a spherical shape surrounded by three hinges, a hinge 13 and a sixth hinge 14 between the right front vertex c and the right rear vertex b of the second rectangular portion 8. Further, the left curved surface portion 8 is the right curved surface portion 7
And the arc-shaped seventh hinge 15 extending from the left front vertex d of the first rectangular portion 5 to the left rear vertex e of the second rectangular portion 6 on the top wall 3 and the first rectangular shape. Left front apex of part 5
And a eighth hinge 16 between the left rear vertex f and a ninth hinge 17 between the left front vertex f and the left rear vertex e of the second rectangular portion 6 form a spherical shape surrounded by three hinges. Further, a rectangular tubular nozzle 18 is vertically provided from the upper surface of the first rectangular portion 5 and a through hole is formed in the first rectangular portion 5 on the lower surface of the nozzle 18 to form a spout 19. . In addition, the second rectangular portion 6
When the closing plate 20 is hung vertically from the lower surface of the front end and the cylindrical nozzle 18 is tilted forward, the inverted top wall portion 4 is inverted and protrudes above the top wall 3, and the closing plate 20 is spouted 19 Is configured so as to close.

When the nozzle 18 is tilted to the front end of the top wall 3, the nozzle 18
A second closing plate 21 is provided upright to close the front opening. Further, from the back surface of the top wall 3, a fitting cylinder portion 22 for fitting into a neck portion (not shown) of the container body is vertically provided.

The spout cap 1 may be integrally molded of synthetic resin.

"Effect of the device" As described above, the liquid pouring cap of the present invention is configured as described above, so that the nozzle can be erected and tilted with one touch, and the pouring port can be opened / closed accordingly, which is very useful in use.
