Abstract

(57) [Abstract] [Purpose] With the protrusion of the self-hinge small, it is difficult for the self-hinge to have a crease and the force to lift the cap during lid application does not increase. Improve the handling of the spout plug so that the spout can be easily operated without the cap covering the spout. [Structure] A hinge strip plate piece 4 of a self-hinge has a substantially arcuate cross section.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spout stopper attached to a spout opening of a liquid paper container or the like.

[0002]

[Prior Art]

 Conventionally, a spout provided on a container such as a liquid paper container for storing liquor, wine, juice, etc. is provided with a substantially cylindrical spout and a cap screwed onto the spout to cover the spout. There are many. If such a spout and the cap are separated, it is not possible to eliminate unsanitary conditions when handling the cap, such as placing it on a table or dropping it on the floor. Due to loss and the like, it is becoming more common to manufacture a spout and a cap that are integrated via a self-hinge. In consideration of the operation of attaching this spout plug with the cap covering the spout at the time of manufacturing the container from the inside of the spout opening of the container, for example, in the applicant's application No. 02-38793, As shown, some ideas have been made to make the entire spout plug tapered.

[0003]

[Problems to be solved by the device]

 However, in the case where the overall shape is tapered as described above, it is necessary to provide a short hinge strip plate so that the self-hinge also has a small protrusion when the lid is applied. For example, as shown in FIG. 3, the spout 1 has a spout 2 and a cap 3 integrated through a self-hinge consisting of a hinge strip 4 to shorten the length of the hinge strip 4. It was a thing. Due to the short length of the hinge strip plate, once the hinge strip plate has a crease, the repulsion when the spout is opened is stronger and the cap is easier to cover. There is a problem that it becomes difficult to pour the contents.

When the inner ring 5 for sealing is provided on the side of the cap 3 as shown in FIG. 4, since the turning radius of the cap 3 is small, when the cap 3 is put on the inner ring, When the opening edge and the nozzle 6 are provided, there is a problem that the nozzle 6 is caught from the outside and it is difficult to close the spout.

Furthermore, once the spout is covered with the cap, the resistance (force to lift the cap) of the hinge strip in this covered state is considerably large, and the cap floats on the self-hinge side. There was also the problem of being prone to

Therefore, the present invention has been made in view of the above-described circumstances, in which the self-hinge is hard to fold and the self-hinge is hard to fold in a state in which the protrusion of the self-hinge (in the covered state) is small. The issue is to prevent the force to lift the cap from increasing even when the lid is closed, to improve the handling of the spout plug, and to make it possible to easily perform spout operation without the spout being covered by the cap. The purpose is to

[0007]

[Means for Solving the Problems]

 The present invention has been made in consideration of the above-described problems, and is attached to the pouring opening of a liquid container, and the pouring opening and a cap that covers the opening and closing are integrated via a self-hinge. In the pouring spout plug, the self-hinge is formed in a substantially arcuate shape in cross section to provide a spout spout plug to solve the above problems.

[0008]

[Action]

 According to the present invention, the length of the hinge strip plate becomes longer, the crease is less likely to be formed, and the turning radius of the cap also becomes larger. Since the hinge strip plate is long on the lid, the internal stress is small and the force to lift the cap is less likely to occur.

[0009]

[Embodiment] Next, the present invention will be described in detail based on an embodiment shown in FIGS. That is, in the present invention, as shown in FIG. 1, a hinge strip plate piece 4 serving as a self-hinging is provided so that its cross-sectional shape is substantially arcuate. The length of the plate piece 4 is increased. Therefore, the hinge strip plate piece 4 is unlikely to have a crease, and when the cap 3 is covered, the hinge strip plate piece 4 is in a circular state and the internal stress applied to the hinge strip plate piece 4 is reduced.

[0010]

[Effect of the device]

 As described above, according to the present invention, in the spout stopper which is attached to the spout opening of the liquid container, and the spout and the cap that covers the openable and closable are integrated via a self-hinge, Since the self-hinge is formed in a substantially arcuate cross section, the self-hinge is long while the protrusion at the time of applying the lid is small, and it is difficult for the self-hinge to bend and the cap covers the spout when pouring. Will disappear. If the turning radius of the cap is large and the cap has an inner ring inside, it is possible to cover the spout properly from above when closing the cap. There is no external contact with the opening edge or nozzle. Especially when the cap is put on the spout, the self-hinge is rounded to give an appropriate force to lift the hinge side of the cap upward, and when the cap is finally fixed in the fitting position, the spout is discharged from the cap free end side. It is possible to perform a good fitting, in which the hinge side is fitted later. Furthermore, since the self-hinge is long when the lid is applied, the internal stress is small, the force to lift the cap does not occur, and it is difficult to break even if the cap is repeatedly opened and closed.
