[0014]

Embodiments of the present invention will be described below with reference to the drawings. A is a container body, and the mouth and neck 1 is erected from the upper end of the peripheral wall via the shoulder. B is a mounting member that projects an inward flange 3 from the upper end of the fitting tube 2 fitted to the outer surface of the mouth and neck portion 1 and hangs a skirt-like wall 4 from the outer surface of the upper end of the fitting tube 2. Then, the lower end of the skirt-shaped wall is brought close to the upper surface of the lower part of the shoulder of the container body, and
The engagement plate 5 is erected from the outer surfaces of the upper ends of the left and right portions of the vehicle. Note that, on the outer peripheral surface of the inward flange 3, an upward engaging step portion 3a with which a lower end of a cap C described later is engaged is formed.

The height of the engaging plate 5 is substantially equal to or slightly higher than the upper surface of the cap top wall described later, and the length of the engaging plate 5 in the front-rear direction is substantially equal to the front-rear direction length of the cap. It is getting longer. The reason why the engagement plate 5 is made to have such dimensions is to prevent an external object from hitting the cap as much as possible and to prevent the cap from opening. In addition, a pair of first engagement ridges 6 project from the inner surface of the upper end of each engagement plate 5 at a predetermined interval in the front-rear direction.

Reference numeral C denotes a cap which hangs the pressing plate 7 from the lower surface of the front half of the top wall of the cylindrical body capable of opening and closing the upper surface of the part of the inward flange 3 between the pair of engaging plates 5. Also, a pair of second engaging ridges 8 are protruded at predetermined intervals in the front-rear direction from the outer surfaces of the upper ends of the left and right peripheral walls of the cylindrical body. The second engagement ridge forms an uneven engagement means which engages with the first engagement ridge 6 when the cap is closed. However, the engagement means is not limited to this, and the engagement means is not limited to this. Engaging projections 6a from the inner surface of the front end of the lower end of the peripheral wall of the body
And an engaging recess 6b is provided on the outer surface of the front end portion of the inward flange 3 to engage the engaging protrusion 6a with the engaging recess 6b as shown in FIG. Means may be formed.

Although the cap C can be formed separately from the mounting member B, it is usually connected to the mounting member B via a thin hinge. That is, the rear end of the lower end of the cylindrical peripheral wall is connected to the rear end of the part of the inward flange 3 between the pair of engagement plates 5 via the thin hinge 9a. Further, rectangular first and second cutouts 9b and 9c are formed at the rear end of the cylindrical body and the upper end of the rear end of the skirt-shaped wall 4, respectively, and one end of the V-shaped elastic bending band 9d is connected to the front edge of the first cutout 9b. And the other end to the second
The lower edges of the cutouts 9c are connected to each other via thin hinges. The first and second cutouts 9b and 9c and the elastic bending band 9d are provided on the left and right sides of the thin hinge 9a to form a three-point hinge together with the thin hinge 9a.

Reference numeral D denotes a pouring member. The inflow cylinder 10 having an upper surface closed is fitted into a flange hole of the inward flange 3 and an outward flange 11 is projected from the lower end of the inflow cylinder to form an upper surface of the outward flange. Is engaged with the lower surface of the inward flange 3.
Then, an elastic pouring cylinder 12 made of a soft material such as silicon rubber is protruded from the front of the peripheral wall of the inflow cylinder 10 to the front upper side. The lower surface of the rear end of the elastic injection tube 12 is engaged with the upper surface of the inward flange 3.

Since the pressing plate 7 is for closing the elastic injection tube 12, the forward projecting length of the elastic injection tube 12 and the vertical length of the pressing plate 7 are different from each other when the cap is closed. The lower end of the plate 7 presses the elastic dispensing tube 12 against the upper surface of the front half of the inward flange 3 so as to close the front end.

Next, the operation of the present embodiment will be described.
In order to close the cap from the open state of the cap shown in FIG. 4, the cap C may be rotated counterclockwise to some extent against the elastic force of the elastic bending band 9d, and the elastic bending band 9d is elastically inverted and the cap is rotated. C rapidly rotates in the same direction and stops with a small gap left between the upper surface of the inward flange 3 and the upper surface.

On the other hand, the pressing plate 7 is brought into contact with the elastic dispensing cylinder 12 by rotating the cap C to push it down. After the rotation of the cap is stopped, the cap may be further pushed down by hand. Then, as shown in FIG.
At the same time, the lower end of the cap engages with the engaging step 3a, and the lower end of the pressing plate 7 presses the elastic dispensing cylinder 12 against the upper surface of the inward flange 3 to close the front end of the elastic dispensing cylinder. .

In the case where the concave and convex engaging means is formed by the engaging concave portion 6b and the engaging projecting portion 6a, the engaging projecting portion 6a is formed by pushing down the cap.
b. Conversely, to close the cap C, the cap may be lifted and rotated clockwise, and the engaging means of the unevenness is released, and the pressing plate 7 is separated from the elastic dispensing cylinder 12, The elastic dispensing cylinder 12 returns to its original shape by the elastic force.

[0023]

According to the first aspect of the present invention, when the cap is fitted, the lower end of the pressing plate presses the elastic dispensing cylinder toward the upper surface of the inward flange to close the elastic dispensing cylinder. There is no need to close the dispensing cylinder with a stopper or the like, so that the stopper can be easily and quickly closed, and this quick and quick operation is extremely useful especially at the time of shipping. In addition, unlike the related art, there is no risk of losing a plug or the like that is separate from the main body, and there is no possibility of forgetting to close the plug, so that the reliability of the plug can be ensured.

In the liquid pouring tap according to the second aspect, since the cap is connected to the mounting cylinder via the thin hinge, the cap is prevented from being lost, and the cap is easily opened and closed.

In the liquid pouring tap according to the third aspect, since the thin hinge is formed by the three-point hinge provided to be elastically reversible, opening and closing of the cap is further facilitated.

In the liquid pouring tap according to the fourth aspect, since the cap is provided with the engaging plate capable of being engaged, the cap can be more reliably closed.

[0027] In the liquid pouring tap according to the fifth aspect, since the engaging concave portion in which the cap is engageable is formed in the mounting cylinder portion, the cap can be more reliably closed as described above.
