Description

  The present invention relates to a spout with a hinge cap that is used by being attached to a pouch such as various seasonings, and more specifically, with the spout fixed to the pouch and having a spout tube attached to the end of the container, The present invention relates to a spout with a hinge cap that is filled with contents through a dispensing tube and that can then be fitted with a hinge cap from above the dispensing tube.

  The spout with a hinge cap includes a spout that is fixed to a container such as a pouch and has a dispensing cylinder, and a hinge cap that is attached to the spout and a cap body and an upper lid are connected via a hinge portion. Spouts are often used to give reliable liquid content to containers that are flexible and easy to dispose of, such as pouches, but are difficult to pour out. On the other hand, hinge caps are easy to open in addition to their openability and increase convenience, and are often used for containers that contain liquid contents that are used frequently such as seasonings, that is, frequently opened and closed. Has been.

A spout with a hinge cap that combines the advantages of the two in this way, with the spout being integrally plugged or screwed into the spout, the spout portion is welded and fixed to the end of the pouch, and is liquid-tight. As described above, the cap body is provided with a pull ring for opening to achieve the above-mentioned easy opening, and can be opened and closed with the hinged upper lid. I have to.

  The spout with a hinge cap described in Patent Document 1 is such that the spout and the cap body are integrally formed via a hinge, and the object is to be virgin regardless of the diameter of the spout. It is excellent and has a configuration in which dust or the like hardly adheres to the spout portion. As described above, spouts with hinge caps are widely used because they are easy to use, but in order to fill liquid contents into containers such as pouches equipped with spouts with hinge caps, a separate pouch is provided. It is necessary to fill the liquid content from the mouth and then close the filling mouth.

  Since the spout fitted with the hinge cap described in Patent Document 1 is filled with the liquid content from a filling port provided separately in the pouch and then closed, the liquid content is high temperature, for example. If there is, it takes time to seal the filling port, and high-speed filling of the liquid contents becomes difficult. As in the current situation, when a spout with a hinge cap is frequently used in a pouch, regardless of the state of the liquid content, high-speed filling is a technical requirement that cannot be avoided. Therefore, to fill the pouch with the liquid content, without filling from the dedicated filling port, the pouch is filled directly from the spout welded to the pouch, and then the hinge cap is fitted to the spout, for example, sealed with a stopper. Then, there is a possibility that high-speed filling of liquid contents can be performed.

  However, when the hinge cap is driven into the spout, it is necessary to consider sufficiently the consistency between the hinge position of the hinge cap, that is, the opening / closing direction of the upper lid and the directionality of the pouch welded to the spout. Furthermore, it is necessary to sufficiently consider the displacement of the hinge cap immediately after the hinge cap is plugged into the spout, for example, to prevent the rotation of the hinge cap, and a spout with a hinge cap that fully considers them is desired.

  Therefore, the object of the present invention is to fill the container with the liquid content from the spout and then attach a hinge cap to the spout, so that the sealing can be finally performed. In this case, the opening / closing direction of the upper lid and the orientation of the pouch are matched. An object of the present invention is to provide a spout with a hinge cap capable of preventing the displacement of the hinge cap and capable of filling the liquid contents at a high speed.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
