である。 The present invention is an improvement of the inner bag with a valve shown in Utility Model Application Publication No. 52-165811 and the inner bag with a valve in the previous invention. The membrane 5 is integrally molded when the valve body 1 is molded, so after the bag making process of the inner bag sealing bag to which the valve body 1 is attached, the inner bag and the carton are joined together. During the process,
Furthermore, during the distribution process as a bag-in box and during material inventory, there is no fear of foreign matter entering through the spout port 4 of the valve body 1.

生産能率の向上に寄与するものである。(Effects of the invention) As described above, in the present invention, the valve attached to the inner bag has a male thread for the cap on the outer surface of the spouting tube, and a disconnection screw on the end surface of the spouting tube that becomes the spouting section. This valve is attached when the inner bag of the bag-in-box is made to form a sealed inner bag with a valve, so the contents are filled from the valve side. After the inner bag is made, it is possible to prevent foreign matter from entering the inner bag during the joining process between the inner bag and the carton, as well as during the bag-in-box distribution process, material inventory, etc. Since there is no need to prepare a separate sealing membrane, the number of processes can be reduced in the production of bag-in boxes that are expected to be used in the future.
This contributes to improving production efficiency.
