[Problems to be solved by the device]

 According to the conventional bag-making filling and packaging bag described above, since the vertical seal is located at the center of the back surface of the bag, the bag has a front side and a back side, and separate printing is required on the front side and the back side of the bag. Both sides must be considered. Also, when the bag is filled with the item to be packed, the bottom of the bag has a square floor shape because gussets are provided on both sides of the bag, but it is pushed by the item to be packed in the bag and both sides of the lower part of the bag are pushed. The shape of the corner floor bag was bad.

The present invention has been devised in view of the above-mentioned points, and when the bag is filled with the article to be packaged without the front and back of the bag, the lower part of the bag is pushed even if the article to be packaged pushes the bag. It is an object of the present invention to provide a bag-making filling and packaging bag in which both sides do not swell and the shape of the square floor bag can be maintained well.

Means for Solving the Problems As a means for solving the above problems, the present invention provides a packaging cylinder H in which vertical seals a and b are provided by aligning inner surfaces of both longitudinal sides of a packaging film F with each other. From the direction perpendicular to the direction in which the lower portion of the vertical seal a of the packaging cylinder H and the lower portion of the vertical seal b of the decoration are retracted inward of the packaging cylinder and the vertical seal a and the vertical seal b of the decoration are opposed to each other. The bottom horizontal seal d is applied, and after the bag is filled with the object to be packaged, the upper part of the vertical seal a of the packaging cylinder H and the upper part of the vertical seal b of the decoration are pulled inward of the packaging cylinder. The present invention provides a bag-filling packaging bag characterized in that a top horizontal seal (f) is provided in a direction orthogonal to the facing direction of the vertical seal (a) and the decorative vertical seal (b).

【Example】

 An embodiment of a bag-making filling packaging bag according to the present invention will be described with reference to FIG. The bag-making filling and packaging bag of this example is shown in FIG. In the bag-making filling packaging bag, the packaging film F is bent into a tubular shape, and the inner faces of the films at both edges are aligned to form a vertical seal a, and the inner faces of the film are aligned from the vertical center line of the film width. A vertical seal b is applied to form a packaging cylinder H, and the vertical seal a of the packaging cylinder H and the vertical seal b of the decoration are retracted inward of the lower portion of the packaging cylinder and a lower gusset c is attached to separate the vertical seal a and the decoration. A bottom horizontal seal d is applied in a direction orthogonal to the direction in which the vertical seal b faces, and after filling the bag with an object to be packaged, the vertical seal a of the packaging cylinder H and the vertical seal b of the ornament are packed in the packaging cylinder. This is a form in which the upper gusset e is retracted inwardly of the upper part, a top horizontal seal f is provided, and a vertical seal a and a decorative vertical seal b are provided on both sides of the bag.

As described above, in order to fold the packaging film F into a vertical cylinder shape and form the packaging cylinder H having the vertical seal a and the decorative vertical seal b, for example, as shown in FIG. Wrap the wrapping film F around the tubular jig 1 whose circumference is shorter than the width of the wrapping film, fold it into a tubular shape, and align the film inner surfaces at both edges of the film with the pair of vertical seal bar heaters 2 and 2. Along with the vertical seal a, an extra portion is secured in the center of the film width, and the film is folded in two and the inner surfaces of the film are aligned with each other.

Further, as described above, in order to attach the gussets c to both sides of the bag, for example, as shown in FIGS. 1C and 1D, two parallel rods 4 and 4 are vertically sealed. a and the vertical seal b of the ornament are inserted from above so as to be opposed to each other on both sides in the packaging cylinder, and the pair of lower gusset plates 5 and 5 vertically seal the inside of the packaging cylinder between the two rods a. Attach the gusset c by thrusting the vertical seal b of the decoration and retracting it.

Further, as described above, in order to apply the bottom horizontal seal d, as shown in FIG. 1D, the lower part of the vertical seal a of the packaging cylinder H and the lower part of the vertical seal b of the decoration are placed inside the packaging cylinder. Then, the bottom horizontal seal d is provided by inserting the pair of horizontal seal bar heaters 6 and 6 from a direction orthogonal to the direction in which the vertical seals a and b face each other.

Further, as described above, in order to apply the top lateral seal f, as shown in FIG. 1 (e), after the object to be packaged is filled in the bag, it is packaged by the pair of upper gusset plates 7, 7. The upper part of the vertical seal a of the cylinder H and the upper part of the vertical seal b of the ornament are retracted inwardly of the bag, the gusset e is attached, and the pair of clamping bars 8 and 8 are used to flatly suppress the vertical seals a and b. A pair of horizontal seal bar heaters 9 and 9 are sandwiched from the direction directly intersecting with and a top horizontal seal f is applied.

In the above embodiment, the packaging film is bent in a vertical tube shape. However, the packaging film is folded in two from the center vertical line of the film width, and the vertical seal a and the decorative vertical seal b are applied to the packaging film. The seal a and the vertical seal b of the ornament may be retracted inward and the lower gusset c may be attached to provide the bottom horizontal seal d, or two wrapping films may be overlapped to form vertical seals on both vertical sides. , B may be formed into a tubular shape, and then the vertical seals a, b may be retracted inward to attach the lower gusset c to the bottom horizontal seal d. Furthermore, this bag-making filling packaging bag is formed by forming a vertical seal a and a decorative vertical seal b with a vertical bag-making filling and packaging machine, and then attaching a bottom gusset c and a bottom horizontal seal d to fill the packaged object. After that, it may be formed by attaching the upper gusset e and applying the top horizontal seal f. The rods 4 and 4 in FIG. 1 (c) may be suspended from the cylinder.
