DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a pouring cap mounted on a container 2. The cap 1 includes a cap body 3 and a cap lid 4.

The cap body 3 has a top wall 7 extending from an upper end edge of a cylindrical peripheral wall 6 having an inner peripheral surface screwed to an outer periphery of the mouth and neck portion 5 of the container body 2 and a spout at a central portion of the top wall 7. 8 are provided. Further, a vertically long concave portion 9 having an open upper end surface and a rear end surface is provided at the rear portion of the peripheral wall 6, and a fitting hole 10 is formed in the lower surface of the concave portion 9 to be fitted with a fitting base portion of a lid described later. .

The cap lid 4 is provided with a rod stopper 12 which fits into the upper spout 8 from the center lower surface of the spherical plate-shaped lid plate 11 covering the upper surface of the cap body 3 and closes the spout 8. ing. Further, a vertically elongated first elastic plate portion 13 is integrally provided from the center of the rear end of the lid plate portion 11, and furthermore, the elastic plate portion 13 is further extended.
The fitting base 14 extends integrally from the lower end. The fitting base 14 includes a horizontal plate 14a protruding forward from the lower edge of the elastic plate 13 and a vertical plate 14b hanging downward from the front end of the lower surface of the plate 14a. In addition, a thin hinge 15 that crosses the upper part of the first elastic plate portion 13 is provided, and the lid plate portion 11 is configured to be rotatable at the hinge 15. Further, a support projection 16 with which a later-described locking plate 19 abuts is protruded above the front edge of the upper surface of the horizontal plate portion 14a, and a pair of second elastic plate portions 17 facing each other upward from both sides thereof. Has been established. Further, locking projections 18 each having a semicircular cross section running vertically on the front end of the inner surface of the second elastic plate portion 17 are provided vertically.

The first elastic plate 1 on the back of the cover plate 11
3 A locking plate portion 19 having a predetermined length is vertically provided at a predetermined interval in front. The locking plate 19 is provided with the second elastic plate 1.
7 so that the lower end surface thereof abuts on the upper surface of the support projection 16 and the front surfaces of both side edges thereof are locked by the respective locking members.
It is locked by a ridge 18. Each locking protrusion as described above
The ridge 18 is formed in a semicircular cross section.
It is structured so that it can be overcome systematically.

The vertical plate portion 14b of the cap lid 4 configured as described above is fitted into the fitting hole 10 of the cap body 3, and the cap lid 4 is mounted on the cap body 3 as shown in FIG. When the cover plate 11 is rotated backward from the state shown in FIG. 1, the lower end of the locking plate 19 rides over each ridge 18 between the second elastic plate portions 17 and the lower end thereof 9 and slide up to the front wall. At this time, the first elastic plate portion 13 below the thin hinge 15 is elastically deformed so that its upper portion is curved backward . When the lower end portion of the locking plate portion 19 is raised to be in a horizontal state, the locking plate portion 19 is pressed against the front wall of the concave portion by the forward urging force of the first elastic plate portion 13, as shown in FIG. As shown in the figure, the cover plate 11 is configured to be stably locked in an open state. Also, when closing the lid plate 11, if the lid plate 11 is pushed forward, the lid 11 rotates around the thin hinge 15, and at this time, the locking plate 19 slides down the front wall again. Then, each second elastic plate portion 17
It is stored in between.

It is preferable that all of the above members are made of synthetic resin.

[0014]

[Effects of the Invention] As described above, the present invention dispensing cap has the above-described structure, so that the cap lid 4 is closed.
When fitted to the main body 3, the locking plate portion 19
Are locked by the locking ridges 18, the first elastic plate portion
13 stably hangs on the lid plate 11 in a hanging state.
Do not rub and stand up from the upper surface of the front of the fitting base 14.
The lower surface of the locking plate 19 abuts and locks on the upper surface of the support protrusion 16 provided.
The fitting base 10 in the fitting hole 10 of the cap body 3.
When the cover 14 is fitted by pushing the part 14
There is no danger of bending through the hinge to 13,
For example, use an existing line that pushes and fits the lid
That can be mounted mechanically and efficiently
Can be performed.
