FIG. 3(B) is a vertical cross-sectional view, and FIG. 3 is a vertical cross-sectional view showing the state of use of the spout with a hinge cap according to the first embodiment.
In the following description, the side on which the lateral rib for mis-opening is provided is the front side, the side on which the hinge is provided is the rear side, and the right side when viewed from the front to the rear is the right side, and the left side is the side on which the hinge is provided. The left side is the side where

The spout 1 with a hinge cap of the present invention is used by attaching it to a gobel-top type paper container 20 (see FIG. 3) for containing liquids such as sake, milk, and tea. The spout 1 with a hinge cap is integrally formed by injection molding a thermoplastic synthetic resin. It is formed with a cap B for closing and a hinge C for connecting the cap B to the spout main body A so that it can be opened and closed.

The spout main body A comprises a thin disc-shaped flange portion 2, a cylindrical spout tube 4 erected in the center of the flange portion 2 via an annular stepped portion 3, and a A partition wall portion 5 forming a bottom portion, a closing plate portion 7 defined so as to be breakable by a breaking line 6 of a predetermined shape recessed thinly in the partition wall portion 5, and a rear (hinge) on the closing plate portion 7. (C side)), and a pull ring 9 connected to the upper end of the column 8. As shown in FIG. By pulling up the pull ring 9 to break a part of the partition wall 5 along the breaking line 6 and removing the closing plate 7, the pouring for pouring the content liquid into the partition wall 5 of the pouring cylinder 4 is performed. It is possible to form the opening 10 as an opening.
At the upper end of the pouring tube 4, a fitting convex portion 4a is formed around the upper end of the pouring tube 4 so as to protrude in the outer diameter direction.

The cap B is a truncated cylindrical member formed with a top surface 11 and a substantially cylindrical outer peripheral wall 12 hanging down from the outer peripheral end of the top surface 11. is provided with an inner cylinder portion 13 tightly fitted to the upper inner peripheral surface of the pouring cylinder 4 . In addition, the lower end of the outer peripheral wall 12 protrudes radially inward in an annular shape, and when the lid is closed, it is fitted to the fitting convex portion 4a on the side of the pouring tube 4 to set the spout with hinge cap 1 in the closed state. A fitting convex portion 12a is provided around the circumference.

The top surface 11 is provided with a base end portion 14A at a front position opposite to the flange portion 2, and is formed in a thin plate shape from the base end portion 14A toward the rear hinge C along the top surface 11. A clip 14 is provided. A tip portion 14B provided behind the clip 14 (on the side of the hinge C) is connected to the top surface 11 in a separable manner. More specifically, a sawtooth-shaped engaging portion 14a is formed at the tip portion 14B, and the tip of the engaging portion 14a and the top surface 11 are separable via a thin weakened portion. Concatenated. When the distal end portion 14B is separated from the top surface 11, the clip 14 can be deformed so that the distal end portion 14B side opens in the direction away from the top surface 11 with the base end portion 14A as a fulcrum (FIG. 3). reference). In this way, the tip portion 14B of the clip 14 is connected to the top surface 11 in a detachable manner, and the clip 14 can be separated when used. It is possible to prevent the clip 14 from unintentionally separating during distribution, especially during the distribution process, from interfering with distribution.

Furthermore, at the position of the front surface of the cap B (the wall surface located forward in the closed state of the outer peripheral wall 12 (see FIG. 1)), between the top surface 11 and the outer peripheral wall 12, a substantially eave-shaped lifting A portion 15 is formed. The horizontal ribs 4 b described above are formed at a position below the lifting portion 15 and close to the lifting portion 15 . By arranging the horizontal rib 4b at a position below the lifting portion 15 in this manner, the hinge cap-equipped pouring spout 1 in the closed state is caught by any member on the lifting portion 15 during the distribution process. The possibility can be reduced, and as a result, it is possible to prevent the cap B from being opened by mistake.

The hinge C is formed, for example, in a bellows-like cross-sectional shape with a plurality of continuous projections and depressions. 12. By rotating the cap B via the hinge C to open and close, the pouring tube 4 can be closed or opened.

As shown in FIG. 2(a), the edges of container-side openings 23 (see FIG. 3) are positioned at a plurality of positions (three positions in this embodiment) in the circumferential direction of the annular stepped portion 3 of the flange portion 2. A retaining projection 3a which is sandwiched between the flange portion 2 and prevents the spout main body A from coming off is projected.

Two lateral vertical ribs 4c having curved ends are projected from the outer peripheral surface on the right side (lower side in the drawing) of the pouring tube 4, and the same applies to the outer peripheral surface on the left side (upper side in the drawing). Three lateral vertical ribs 4c are provided. The plurality of side vertical ribs 4c are loaded into a parts feeder (not shown) with the spout 1 with hinge cap closed, and fed one by one to a shooter (not shown) comprising a plurality of guide rails and the like for the next step. It is used to control the orientation of the spout 1 with a hinge cap by giving vibration or rotation during the process of being transported to the process of attaching to the paper container 20, which is the process of (1).

Next, a method of using the spout with hinge cap having the above configuration will be described.
As shown in FIG. 3, the spout 1 with hinge cap is attached to a container-side opening 23 formed on a sloped roof 22 below a top seal portion 21 of a paper container 20 for use. When attaching, the orientation of the spout 1 with the hinge cap is adjusted so that the rear hinge C is positioned on the top seal portion 21 side.
To open the spout 1 with a hinge cap, insert a fingertip or a fingernail between the horizontal rib 4b and the raised portion 15 to lift the raised portion 15, and the fitting convex portion 4a on the side of the spout main body A and the cap B. After releasing the fitting with the fitting protrusion 12a on the side, the cap B is rotated about the hinge C in the opening direction.

In order to hold the cap B at the open position and maintain the open state, the tip of the engaging portion 14a of the clip 14 is separated from the top surface 11 to set the clip 14 to the open state, and the clip 14 and the top are separated. The top seal portion 21 is inserted between the paper container 20 and the surface 11, and the top seal portion 21 of the paper container 20 is locked by the locking portion 14a. The opening angle θ of the clip 14 can be arbitrarily set around the proximal end portion 14A. Further, the engaging portion 14a is formed to have a serrated shape, and has an effect of preventing slipping. Therefore, the clip 14 can reliably lock the top seal portion 21 with its locking portion 14a, and the clip 14 does not easily come off after locking. status can be maintained.
Alternatively, the click 14 may be separated from the top surface 11 first, and then the cap B may be opened and held at the open position.

Subsequently, as described above, the pull ring 9 is pulled up to break a part of the partition wall 5 along the breaking line 6 to remove the closing plate 7, and the pouring opening 10 is formed to open the container side opening 23. By connecting the pouring opening 10 to the , it becomes possible to pour out the content liquid through the pouring port 1 with the hinge cap.
During the work of pouring out the content liquid, the open state of the cap B is maintained, and the cap does not block the upper end of the pouring tube 4 and interfere with the work, so that the pouring work can be carried out without any trouble. can do well.

After the pouring operation is completed, the opening angle θ of the clip 14 is adjusted to release the locking of the top seal portion 21 by the locking portion 14a. By fitting the fitting protrusion 4a on the A side with the fitting protrusion 12a on the cap B side, the lid can be closed. In this closed state, the inner cylindrical portion 13 on the side of the cap B is closely fitted to the upper inner peripheral surface of the pouring tube 4 on the side of the spout main body A, so that the pouring tube 4 can be reliably sealed. is.
Since the opening angle θ of the clip 14 can be adjusted in this manner, the clip 14 may be attached in a state of being inclined with respect to the top seal portion 21, or the top may be positioned at a position slightly deviated from the rotational trajectory of the clip 14. Even when the seal portion 21 is positioned, it is possible to lock the locking portion 14a and the top seal portion 21 by appropriately adjusting the opening angle θ.

It is a longitudinal cross-sectional view showing a state of use.

The main difference between the spout 1 with a hinge cap as the second and third embodiments and the above-described first embodiment is the configuration of the clip 14 or the top surface 11, and the other configurations and effects are the same as those of the first embodiment. Since this embodiment is the same as the example, the following description will focus on the differences from the first embodiment, and the same members will be assigned the same reference numerals.

In the spout 1 with hinge cap shown as the second embodiment in FIG.
With this configuration, it is possible to easily pull up the clip 14 by inserting a fingertip into the opening 14C. Clip 14 can be set to an open state.
Then, as shown in FIG. 5, by using the separated clip 14, it is possible to keep the cap B in the open position and maintain the open state in the same manner as described above.

In the spout 1 with a hinge cap shown as a third embodiment in FIG. 6, a recess 11A is provided at a position one level lower than the top surface 11 of the cap B, and the clip 14 is accommodated in this recess 11A. The depth dimension of the recess 11A is set so that the upper surface of the clip 14 and the top surface 11 are flush with each other.
With this configuration, the clip 14 does not protrude upward from the top surface 11, so that the clip 14 is prevented from being inadvertently separated from the top surface 11 especially in the process of distribution, thereby preventing the clip 14 from interfering with distribution. be able to.
As shown in FIG. 7, by using this clip 14, it is possible to keep the open state of the cap B by holding it in the open position in the same manner as described above.
It goes without saying that in the third embodiment, as in the second embodiment, the clip 14 may be provided with the opening 14C.

As described above, the configuration and effects of the present invention have been described according to the embodiments, but the embodiments of the present invention are not limited to the above embodiments.
For example, in the above-described first to third embodiments, the partition wall portion of the pouring tube 4 is removed by pulling up the pull ring 9 to break a part of the partition wall portion 5 along the breaking line 6 and removing the closing plate portion 7. 5 for pouring out the content liquid has been described, but the present invention is not limited to the above-described embodiment, and the pouring opening 10 or the container-side opening is provided in advance. The portion 23 may be sealed with a sealing material, and the configuration may be such that the sealing material is removed before use.
