For example, as shown in FIG. 9A, the cleaner nozzle 641 can be inserted from the spout 112 into the gap. As an example, the cleaner nozzle 641 is provided with a suction pipe 641a (not shown) having a suction port at the lower end capable of sucking in foreign matter together with air, and is disposed concentrically with the suction pipe 641a to the outside of the suction pipe 641a. It can be constituted by an air nozzle 641b (not shown) provided with a jet port that can be used at the lower end. The cleaner nozzle 641 can suck and remove the foreign matter wound up in the gap by the ejected air by simultaneously ejecting and sucking air at the lower end.

[Content filling mechanism]
The content filling mechanism 650 fills the space in the packaging container 100 with the content. As shown in FIG. 9B, the content filling mechanism 650 can fill the content into the gap from the opening 111 by the filling nozzle 651 inserted into the spout 112.

[Cap supply mechanism]
The cap supply mechanism 660 supplies the cap 500 to the spout 112. The cap supply mechanism 660 covers the spout 112 with a cap 500 supplied from a parts feeder (not shown), for example, as shown in FIG. The supply method of the cap 500 is not particularly limited, and an operator may put the cap 500 on the spout 112 by manual work.

[Cap mounting mechanism]
The cap attachment mechanism 670 closes the spout 112 by attaching the cap 500 to the spout 112. As shown in FIG. 9D, the cap mounting mechanism 670 can mount the cap 500 to the spout 112, for example, by holding the side surface 120 of the packaging container 100 and fixing the packaging container 100. And a capper (not shown).

  The cap mounting mechanism 670 mounts the cap 500 by rotating the spout 112 with a capper while the packaging container 100 is supported by the second support portion 671. As a result, the spout 112 is closed.

  As long as the cap that closes the spout 112 can close the spout 112, it may be a cap through which the bump dispenser penetrates in the vertical direction as shown in FIG.

[Discharge of packaging container]
In this way, the packaging container 100 molded by the molding and filling device 600 and filled with the contents is discharged to the outside of the main molding and filling device 600 and delivered to, for example, a later line.

  The molding and filling apparatus 600 described above may be configured such that each mechanism sequentially processes the packaging container 100 placed on one stage, or each mechanism is disposed on a different stage to form the packaging container 100. May be sequentially processed while moving on each stage.

  Further, in the molding and filling apparatus 600, the first air nozzle 611, the second air nozzle 621, and the third air nozzle 631 have been described as separate configurations. However, at least any two of these have the same air nozzle. You may comprise so that it may share.

  Similarly, at least any two of the first side seal portion bent portion 622, the second side seal portion bent portion 632, and the third side seal portion bent portion 633 share the same jig. You may comprise as follows.

  As described above, according to the packaging container molding and filling apparatus according to the present invention, the cap is formed after the packaging container, which has been sealed in a flat state with its end sealed in advance, is transformed into a box shape and filled with the contents. It can be sealed by, for example. Therefore, there is no sealing process for securing the sealing property in the molding and filling apparatus of the packaging container, and it is not necessary to guarantee the sealing performance by the molding and filling apparatus of the packaging container. As a result, a decrease in production efficiency can be suppressed.

  The present invention can be suitably used for manufacturing a packaging container filled with contents.
