JPH0714209Y2 - Mouth with cap - Google Patents

Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a mouth with a cap made of synthetic resin, which is used by attaching it to a bottle mouth, etc. Regarding stoppers.

(Prior art) A cap with a cap attached to a bottle mouth or the like has a high utility value without losing the cap, but it can be created by a single injection molding from the manufacturing side, and the bottle mouth is capped. Even in the case, it is a form that has many advantages such as being able to cap together with the cap.

Also, recently, many ideas have been made around the spout of the spout. For example, there is one in which a return groove is provided around the spout and a part of the spout is cut off to be used as a return port in order to return the liquid dripping on the outer wall surface of the spout to a container such as a bottle. . There is also a spout having a cylindrical shape so as to eliminate the direction of pouring. The spout with a cylindrical spout often fills the container with the spigot filled with a liquid such as dressing, but keep it from flowing out of the spout even if the container collapses. An annular wall is projected on the ceiling surface on the cap side and abutted against the inner wall surface of the spout to prevent the outflow.

(Problems to be Solved by the Invention) Although a spout body having a cylindrical spout and a cap body having an annular wall are integrated by a hinge, since the hinge is thin, the cap body is attached to the spout body. If the cap body is distorted during crowning, there is a problem that the spout and the annular wall collide with each other and it is difficult to crown. Further, there is a problem that the sealability between the spout and the annular wall is not sufficient just by making contact with each other.

In consideration of the above problems, the present invention enables the cap body to be smoothly crowned even when the cap body is distorted and crowned the spout, and the sealing property of the spout is improved. A cap with a cap is provided.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention is a synthetic resin port formed by connecting a cap body (3) to a spout body (1) via a hinge (2). In the stopper, the spout body (1) has a cylindrical spout (4) having an upwardly expanded diameter in a substantially central portion, and is connected to the spout body (1) via a hinge (2). On the ceiling surface (3a) of the cap body (3), when the cap body (3) is capped on the spout body (1), the cap body (3) comes into contact with the outer peripheral edge (4a) of the tip of the spout (4). An annular wall (5) forming one annular wall surface (5a) and a second annular wall surface (6a) located inside the annular wall (5) and abutting the inner peripheral surface of the tip of the spout (4). ) Is formed to form an annular groove (7) between the annular walls, and the second annular wall (6)
On the annular wall (6) and the inner peripheral side thereof, guide walls (8) whose height increases toward the center are formed at appropriate intervals over the entire circumference.

(Operation) Because of the above configuration, when the cap body (3) is capped on the spout body (1), the guide wall is distorted in any direction when the opening of the cap body (3) is distorted. The annular groove (7) formed on the ceiling surface (3a) by (8) maintains a certain shape, and the tip shape of the spout (4) is the annular groove (7) along the height shape of the guide wall (8). ) Fit and fit. The tip of the spout (4) fitted in the annular groove (7) has first and second annular wall surfaces (5a, 6a).
Since it is pressed against the bottom of the annular groove (7) as well as abutting against, the sealing performance is improved.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

The synthetic resin spout of the present invention comprises a spout body 1, a cap body 3, and a strip-shaped hinge 2 integrally connecting both.

The spout main body 1 has a substantially cylindrical shape, and has a cylindrical spout 4 with an enlarged diameter in the center thereof, and an annular fitting groove 9 that fits into the mouth of a container A such as a bottle in the lower part. The inside of the spout 4 is closed by a removing portion 11 surrounded by a weak line 10.
The removing portion 11 is integrally formed with a handle 12 for removing this portion from the weakened line 10. An annular wall 13 which is shorter than the spout 4 is provided around the spout 4, and a groove is formed therebetween. The outer peripheral surface of the annular wall 13 has an engaging protrusion 13a.

The cap body 3 has a substantially cylindrical shape with a diameter that matches the diameter of the spout body 1, and three concentric annular walls 5, 6, 14 project from the ceiling surface 3a thereof.

Further, the annular walls 5 and 6 form an annular groove 7 having a U-shaped cross section between them. Further, a plurality of guide walls 8, 8, ... Are integrally formed over the entire circumference of the annular wall 6 and the annular wall 14 at appropriate intervals, and the guide wall 8 is higher on the annular wall 14 side. And it is inclined at an angle. In the embodiment, two guide walls 8, 8, ... Are arranged in the cross direction. In the figure, 3b is an engaging protrusion.

With the above configuration, when the cap body 3 is tilted upward from the state shown in FIG. 1 to the position shown in FIG. The guide wall 8 that contacts the spout 4 slides in the direction of the annular groove 7 while being guided by the inclined surface thereof.
Even if the opening is distorted, the spout 4 is guided by the inclination of the guide wall 8 and aligned with the annular groove 7 as the lid is closed. Finally, as shown in FIG. 4, the entire periphery of the spout 4 is introduced into the annular groove 7 and fitted therein, and the spout body 1
The engagement protrusion 13a of 1 and the engagement protrusion 3b of the cap body 3 are engaged with each other.

(Effects) Since the present invention is configured as described above, distortion of the ceiling surface of the cap body can be prevented and distortion of the spout can be corrected, so that the cap body can be crowned with respect to the spout body extremely smoothly. In addition, leakage of the liquid filled in the container can be effectively prevented by fitting the annular groove and the spout.
