う問題があつた。 Conventionally, packaging bags in which a hard spout is provided on a flexible bag body are usually attached to the bag body by thermal bonding, but it is difficult to obtain uniform adhesive strength. In addition, some products are made by attaching the spout by heat-bonding the bag material at the same time when forming the bag body, but this is not only cumbersome to manufacture, but also tends to cause variations in adhesive strength. There was a problem of poor reliability due to concerns about peeling or liquid leakage.
本考案はこのような問題点を解決するものであ

した。 The present invention solves these problems by forming a flexible spouting pipe that protrudes outward from the bag body, and an inner cylinder is inserted into this spouting pipe. An outer cylinder is forcedly fitted over the inner cylinder insertion portion of the pipe, and circumferential grooves and protrusions formed on the inner cylinder and the outer cylinder sandwich the spout pipe. The structure is such that they are closely fitted together.

９を互いに一体的に固着している。 At the lower end of the bottom part 5, a flexible spouting tube 6 with a small diameter tip is integrally formed with the bag body 4, communicating with the inside of the bag body 4 and protruding to the outside. An inner cylinder 8 having the same shape or a slightly larger outer shape than the inner shape of the spouting tube 6 and having shape retention and elasticity is inserted into the spouting tube 6 from the opening 7 at the upper end of the bag body 4. Therefore, the spout pipe 6 and the inner cylinder 8 are in close contact with each other. In addition, the outer tube 9, which has an inner shape that is the same as or slightly larger than the outer shape of the inner tube 8 and has shape retention and elasticity, is forcibly fitted into the inner tube 8 from above the spouting tube 6. It is embedded in. Furthermore, grooves 10 and protrusions 11 extending in the circumferential direction are formed on the outer circumferential surface of the inner cylinder 8 and the inner circumferential surface of the outer cylinder 9, and these insert the spout pipe 6 and fit into each other. In cooperation with the forced fitting, the spout pipe 6. Inner cylinder 8. The outer cylinders 9 are integrally fixed to each other.

く安全に取扱えるものである。 As described above, the present invention has a flexible spout pipe that is sandwiched between an inner cylinder on the inside and an outer cylinder that is fitted on the outside by force fitting, and a spout is formed by the fit and fixation. Therefore, since the spout tube is formed integrally with the bag and is not thermally bonded, it is possible to easily manufacture a spout with uniform strength using a minimum number of parts. Further, the outer cylinder is fitted from above the spout pipe by force fitting, and the grooves and protrusions in the circumferential direction of the inner cylinder and the outer cylinder insert the spout pipe and fit into each other. Therefore, they fit tightly together without any gaps, maintaining complete liquid-tightness and airtightness, and preventing liquid leakage. By providing the inner and outer cylinders with appropriate hardness, it becomes possible not only to push the spout into the bag and store and package it in the outer box, but also to pull it out to open it and pour out the contents. At that time, since the inner cylinder and the outer cylinder are engaged with each other by the concave lines and the convex lines, there is no fear that they will separate and break even if a strong tensile force is applied, and it can be handled safely.
