Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a spout stopper that can be attached to the spout hole of a liquid container made mainly of paper. There are things like that.

0002

[Conventional technology]

Conventionally, this type of spout stopper has a flange integrated around the lower end. This flange is attached around the spout hole opened in the liquid container by means such as ultrasonic welding. By welding and fixing the spout, the spout can be attached to the liquid container. It's coming.

0003 And in recent years, tear-off spout plugs with pull rings have been developed for this spout stopper. The opening method has been adopted, and the addition of a pouring tongue has been devised. As a result, the spout plug itself has become directional. Make sure that the above-mentioned flanges are installed so that this spout plug is oriented in the correct direction. By protruding one side of the pipe and making the protruding part heavier, the spout during the spout plug installation process is When supplying taps, the direction of the spout plugs that are guided in an array depends on the position of their center of gravity. I tried to make it change, and I tried to align the direction with a guide.

[Problem that the idea aims to solve]

By the way, regarding the spout stopper mentioned above, consider the number of parts that make up the spout. In consideration of this, instead of a cap that closes the spout stopper by screwing, a lid is installed via a hinge. Attempts to integrate the body into one piece have begun to be considered. However, in a spout plug that has this lid integrally, it is difficult to open the spout plug. Sometimes, the lid is located close to the top of the spout barrel, so the liquid container is This lid must not get in the way when pouring out the container, and the spout plug must be There was a problem that the spout plug had to be installed in the same direction when installed. .

[0005] Therefore, in view of the above-mentioned circumstances, this invention requires improvements such as the supply device of the spout stopper. This spout stopper, which has an integrated lid, can be aligned in the correct direction when installed. The challenge was to supply the product in the same condition, and by providing a protrusion on the above-mentioned flange to give directionality. We focused on this technology to ensure that the spout plug can be properly attached to the spout hole of the liquid container. The purpose is to

[0006]

[Means to solve the problem]

This invention was created in consideration of the above-mentioned problems, and it is designed to be attached to the spout hole of a liquid container. A spout plug that can be removed, and is welded to the lower end of the spout barrel around the spout hole of the liquid container. A flange is provided at the upper end of the spout barrel for opening and closing the opening of the spout barrel. A lid body is rotatably provided via a hinge, and a lateral lid body is provided on one side of the flange. A spout plug installation direction regulating protrusion is provided that protrudes from the spout, and this protrusion at the upper end of the spout barrel is Provided is a spout plug for a liquid container, characterized in that the hinges are located on opposite sides. This is intended to solve the above problems.

[0007]

[Effect]

In the present invention, the spout plug is equipped with a protrusion for regulating the mounting direction of the spout plug. The center of gravity of the spout is moved toward this protrusion, giving directionality to the spout stopper, and the lid body By positioning the hinge on the side facing the protrusion, the direction of rotation of the lid body is aligned with the spout plug itself. When the spout plug is installed based on the correct orientation of the body, Even when the lid is opened, the lid comes to a position where it does not interfere with pouring.

[0008]

【Example】

Next, the present invention will be explained in detail based on the embodiment shown in FIGS. 1 and 2. 1 in the figure is a spout plug, and the spout plug 1 has a cylindrical spout body 2 as shown in FIG. A closing plate 4 equipped with a pull ring 3 is integrally provided inside the housing with a thin wall portion 5 interposed therebetween. When the pull ring 3 is pulled, the thin wall portion 5 is broken and the closing plate is 4 is removed and the package can be opened. Also, around the lower end of the outer circumference of the pouring body 2 is provided with a flange 6, which is melted around the spout hole of the liquid container. By attaching the spout plug 1 to the liquid container, the spout plug 1 is attached and fixed to the liquid container.

[0009] One side of this flange 6 has a protrusion that protrudes laterally to regulate the mounting direction of the spout plug. A pair of 7 are provided. This protrusion 7 causes the center of gravity of the spout plug 1 to be biased toward the protrusion 7. The protrusion 7 has directionality while being guided on the guide of the spout plug automatic supply device. The spout plugs are arranged with the liquid container facing downward, and the spout plugs are aligned in the same direction. It will now be set in the exit hole.

0010 On the other hand, a self-hinge 8 is provided at the upper end of the spout barrel 2 on the side opposite to the protrusion 7. A lid body 9 is integrally provided, and this lid body 9 can rotate to open and close the pouring body 2. cover. Since the self-hinge 8 is located on the side facing the protrusion 7, the spout plug 1 is The proper orientation and the rotating direction of the lid body match, that is, the state in which the protrusion 7 is directed downward. When the lid 9 is opened, it rotates upward, and as described above, the spout stopper 1 is opened. When set and fixed in the spout hole, the self-hinge 8 is also in the proper position, Even when the lid is open, it does not get in the way when pouring.

[0011] As shown in FIG. 2, a plurality of triangular plate-shaped ribs 10 are provided around the spout barrel 2. It is provided across the flange 6, and the shape of one side of the spout plug 1 is approximately flat-headed. It has a conical shape, and when it is set in the spout hole, this rib 10 acts as a guide to ensure that it is in the correct position. It will be possible to install it. As a result, the outer diameter of the spout barrel 2 becomes smaller than that of the spout. The lower space A of the closing plate 4 is smaller than the diameter by two ribs, and the spout plug supply device is This has the effect of allowing the suction and holding operation to be performed reliably in a short period of time. It becomes like this.

[Effect of the idea]

As explained above, according to the present invention, the pourer attached to the spout hole of the liquid container The outlet plug includes a flang welded to the lower end of the spout barrel around the spout hole of the liquid container. A lid body for opening and closing the opening of the spouting barrel is provided at the upper end of the spouting barrel. It is rotatably provided via a hinge and protrudes laterally from one side of the flange. A projection for regulating the mounting direction of the spout plug is provided, and the side opposite to this projection at the upper end of the spout barrel is provided with a projection for regulating the mounting direction of the spout plug. Since the hinge is located at The spouts are now supplied in the same order, and the opening and closing direction of the lid body is correct when opening the spout. This has excellent practical effects, such as the ability to attach a stopper.
