FIG. 3B is a vertical cross-sectional view, and FIG. 3 is a vertical cross-sectional view showing a usage state of a spout with a hinge cap according to the first embodiment.
In the following description, in the injection cylinder, the side where the horizontal rib for erroneous opening is provided is the front, the side where the hinge is provided is the rear, and the side which is the right when viewed from the front to the rear is the right and the left. The side that becomes is the left side.

The spout 1 with a hinge cap of the present invention is used by being attached to a Goebel top type paper container 20 (see FIG. 3) for containing a content liquid such as liquor, milk, or tea. The spout 1 with a hinge cap is integrally molded by injection molding a thermoplastic synthetic resin, and is largely composed of a spout body A for pouring out the content liquid in a paper container and a spout body A. It is formed to have a cap B for closing the lid and a hinge C for connecting the cap B to the spout main body A so as to be openable and closable.

The spout main body A has a flange portion 2 made of a thin disk shape, a cylindrical pouring cylinder 4 erected in the center of the flange portion 2 via an annular step portion 3, and a pouring cylinder 4 inside the pouring cylinder 4. A partition wall portion 5 forming a bottom portion, a closing plate portion 7 fragilely defined by a breaking line 6 having a predetermined shape recessed in the partition wall portion 5, and a rear (hinge) on the closing plate portion 7. It is configured to have a pillar portion 8 erected at the position (C side) and a pull ring 9 connected to the upper end of the pillar portion 8. By pulling up the pull ring 9 to break a part of the partition wall portion 5 along the break line 6 and removing the closing plate portion 7, the content liquid is poured out to the partition wall portion 5 of the injection cylinder 4. It is possible to form an opening 10.
A fitting convex portion 4a projecting in an annular shape in the outer diameter direction is provided around the upper end of the dispensing cylinder 4, and a lateral rib 4b is provided at a position in front of the dispensing cylinder 4.

The cap B is an ecstatic tubular member formed by having a top surface 11 and a substantially cylindrical outer peripheral wall 12 suspended from the outer peripheral end of the top surface 11, and is formed on the inner surface of the top surface 11. Is provided with an inner cylinder portion 13 that is tightly fitted to the upper inner peripheral surface of the injection cylinder 4. Further, the lower end of the outer peripheral wall 12 is annularly projected inward in the radial direction, and when the lid is closed, the spout 1 with a hinge cap is set to the closed state by fitting into the fitting convex portion 4a on the pouring cylinder 4 side. A fitting convex portion 12a for the purpose is provided around the circumference.

Further, 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. The tip portion 14B provided behind the clip 14 (on the hinge C side) is connected to the top surface 11 in a separable state. More specifically, a sawtooth-shaped locking portion 14a is formed on the tip portion 14B, and the tip of the locking portion 14a and the top surface 11 can be separated from each other via a thin-walled weakened portion. It is connected. Then, when the tip portion 14B is separated from the top surface 11, the clip 14 can be deformed so that the tip 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 separable state, and the clip 14 may be separated at the time of use. Therefore, from immediately after molding until the clip 14 is separated. During, especially in the distribution process, it is possible to prevent the clip 14 from being inadvertently separated and interfering with the distribution.

Further, at the position of the front surface of the cap B (the wall surface of the outer peripheral wall 12 located in the front in the closed state (see FIG. 1)), the upper surface 11 and the outer peripheral wall 12 are pulled up in a substantially eaves shape. The portion 15 is formed. The above-mentioned lateral rib 4b is formed at a position below the pulling portion 15 and close to the pulling portion 15. By arranging the lateral rib 4b at a position below the pull-up portion 15 in this way, any member of the hinge-capped spout 1 in the closed state is caught by the pull-up portion 15 in the distribution process. The possibility can be reduced, and as a result, it is possible to prevent the cap B from being erroneously opened.

The hinge C is formed, for example, in a bellows shape in a cross-sectional view in which a plurality of irregularities are continuous, the lower end is connected to the outer peripheral surface of the pouring cylinder 4 constituting the spout main body A, and the upper end is the outer peripheral wall forming the cap B. It is connected to 12. By rotating the cap B through the hinge C to open and close, the pouring cylinder 4 can be closed or opened.

As shown in FIG. 2A, the edges of the container-side opening 23 (see FIG. 3) are provided at a plurality of positions (three locations in this embodiment) in the circumferential direction of the annular step portion 3 of the flange portion 2. A retaining protrusion 3a is provided so as to be sandwiched between the flange portion 2 and prevent the spout main body A from coming off.

Further, two lateral vertical ribs 4c having a curved tip formed on the outer peripheral surface on the right side (lower side in the drawing) of the pouring cylinder 4 are projected, and the same applies to the outer peripheral surface on the left side (upper side in the drawing). Three lateral vertical ribs 4c are projected. These plurality of lateral vertical ribs 4c are loaded into a parts feeder (not shown) with the hinged capped spout 1 closed, and are fed one by one to a shooter (not shown) composed of a plurality of guide rails or the like. It is used to control the direction of the spout 1 with a hinge cap by applying vibration or rotation in the process of being conveyed to the process of attaching to the paper container 20 which is the process of.

Next, how to use the spout with a hinge cap having the above configuration will be described.
As shown in FIG. 3, the spout 1 with a hinge cap is used by being attached to the container-side opening 23 formed on the inclined roof portion 22 under the top seal portion 21 of the paper container 20. At the time of attachment, the direction of the spout 1 with a hinge cap is adjusted so that the rear hinge C is located on the top seal portion 21 side.
To open the spout 1 with a hinge cap, insert a fingertip or a claw between the lateral rib 4b and the pulling portion 15 to lift the pulling portion 15, and then lift the pulling portion 15 and fit the convex portion 4a and the cap B on the spout main body A side. After the fitting with the fitting convex portion 12a on the side is released, the cap B is rotated around the hinge C in the lid opening direction.

In order to hold the cap B in the open position and maintain the lid open state, the tip of the locking portion 14a of the clip 14 is separated from the top surface 11 to set the clip 14 in the open state, and the clip 14 and the top are set. The top seal portion 21 is inserted between the surface 11 and the top seal portion 21 of the paper container 20 at the locking portion 14a. The opening angle θ of the clip 14 can be arbitrarily set around the base end portion 14A. Further, the locking portion 14a is formed to have a sawtooth shape, and is also effective as a non-slip. Therefore, the clip 14 can securely lock the top seal portion 21 with the locking portion 14a, and does not easily come off after locking. Therefore, the cap B is held in the open position to open the lid. It becomes possible to maintain the state.
The click 14 may be separated from the top surface 11 first, and then the cap B may be opened and held in the open position.

Subsequently, as described above, the pull ring 9 is pulled up to break a part of the partition wall portion 5 along the break line 6 to remove the closing plate portion 7, and the injection opening 10 is formed to form an opening on the container side 23. By communicating the pouring opening 10 with the pouring opening 10, the content liquid can be pouring out through the pouring outlet 1 with a hinge cap.
During the pouring work of the content liquid, the open state of the cap B is maintained, and the cap does not block the upper end of the pouring cylinder 4 and interfere with the work, so that the pouring work is not hindered at all. It can be done well.

After the pouring work is completed, the opening angle θ of the clip 14 is adjusted to release the lock of the top seal portion 21 by the locking portion 14a, and then the cap B is rotated in the closing direction to the spout main body. The lid can be closed by fitting the fitting convex portion 4a on the A side and the fitting convex portion 12a on the cap B side. In this closed state, the inner cylinder portion 13 on the cap B side is tightly fitted to the upper inner peripheral surface of the injection cylinder 4 on the spout main body A side, so that the pouring cylinder 4 can be securely sealed. Is.
In this way, since the opening angle θ of the clip 14 can be adjusted, the clip 14 is attached in a tilted state with respect to the top seal portion 21, or the top is slightly deviated from the rotation trajectory of the clip 14. Even when the seal portion 21 is located, the locking portion 14a and the top seal portion 21 can be locked by appropriately adjusting the opening angle θ.

FIG. 4 is a vertical cross-sectional view showing a closed state of the spout with a hinge cap as a second embodiment of the present invention, and FIG. 5 is a vertical cross-sectional view showing a state of use of the spout with a hinge cap as the second embodiment. 3 shows the closed state of the spout with a hinge cap as the third embodiment of the present invention, (a) is a plan view, (b) is a vertical sectional view, and FIG. 7 is a spout with a hinge cap according to the third embodiment. It is a vertical cross-sectional view which shows the use state.

As the second embodiment and the third embodiment, the hinged capped spout 1 is different from the first embodiment described above in the configuration of the clip 14 or the top surface 11, and the other configurations and effects are the first embodiment. Since it is the same as the example, the same members will be described below with the same reference numerals, focusing on the differences from the first embodiment.

In the spout 1 with a hinge cap shown as a second embodiment in FIG. 4, an opening 14C is provided between the base end portion 14A and the tip end portion 14B of the clip 14.
In this configuration, since the clip 14 can be easily pulled up by inserting the fingertip into the opening 14C, the thin-walled weakened portion connecting the tip portion 14B of the clip 14 and the top surface 11 can be easily separated. The clip 14 can be set to the open state.
Then, as shown in FIG. 5, by using the separated clip 14, the cap B can be held in the open position and the lid open state can be maintained 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 step lower than the top surface 11 of the cap B, and the clip 14 is housed in the recess 11A. The depth dimension of the recess 11A is set so that the upper surface of the clip 14 is flush with the top surface 11.
In this configuration, since the clip 14 does not protrude upward from the top surface 11, the clip 14 does not inadvertently separate from the top surface 11 especially in the distribution process, so that the clip 14 does not interfere with the distribution. be able to.
Then, as shown in FIG. 7, by using this clip 14, it is possible to keep the cap B in the open position and keep the lid open state in the same manner as described above.
Of course, also in the third embodiment, as in the second embodiment, a configuration in which the opening 14C is provided in the clip 14 may be adopted.

Although the configuration of the present invention and its action and effect have been described above with reference to Examples, the embodiments of the present invention are not limited to the above Examples.
For example, in the first to third embodiments, the pull ring 9 is pulled up to break a part of the partition wall portion 5 along the break line 6, and the closing plate portion 7 is removed to remove the partition wall portion of the pouring cylinder 4. Although the configuration in which the pouring opening 10 for pouring the content liquid is formed is shown in No. 5, the present invention is not limited to the above embodiment, and the pouring opening 10 or the container side opening is described in advance. The portion 23 is sealed with a sealing material, and the sealing material may be peeled off for use.

The present invention can be applied to a wider range of applications in the field of a spout with a hinge cap used by being attached to a paper container.
