Opening is performed by tearing up from the side notch 11 and opening the upper part of the zipper 3 to the butt-seaming edge to make an exhaust port of contents, and filling of the contents is performed on a bottom 15 side of the fully opened bag body 1.

Description

  The present invention relates to a so-called zippered pillow packaging bag in which a joint-pasted part is positioned at or near the center of the back side of the bag body, and a zipper is attached in the opening portion of the bag body, and more specifically, The attachment position of the zipper is a part of the unsealing opening, and the amount of the zipper opening is formed when the contents portion is discharged from the bag by forming the zipper opening small by attaching the zipper opening to the side edge of the bag. It is designed so that it can be easily discharged and the contents are filled into the bag, so that the entire bag width can be made at a stretch from the bottom of the opened bag, thereby improving the efficiency of the contents filling operation. The present invention relates to a pillow packaging bag with a zipper configured to increase productivity and a method for manufacturing the same.

  In the case of a conventional pillow packaging bag with a zipper, the zipper is attached to the entire bag width at the opening (Japanese Patent Laid-Open No. 2013-028394).

  For this reason, when opening the zipper, the entire bag width is opened at the opening, and the opening may be too large and the contents may be discharged more than necessary. Further, when closing the zipper, if the opening is large, the zipper's occlusal portion becomes longer, so that fitting takes time and a part that cannot be completely closed may remain. In addition, the zipper cannot be completely closed in the case of a handicapped person, an elderly person, or a small child.

  For this reason, in a bag formed with a three-sided seal and a bottom gusset, it is formed by projecting so that the opening is about 1/2 of the bag width, and a zipper is attached to this to open the width of the bag opening. Has been proposed (utility model registration No. 3129623).

  However, in this proposal, a zipper attachment region is formed to protrude about half on the opening side of the three-side seal bag, and the content inlet is formed in the lower half, which is a lower step. Is a structure that heat seals after filling the contents, so even if you try to attach the zipper in this way in the pillow packaging bag with zipper, the jointed part is located in the center of the bag, The sticking part gets in the way, heat sealing becomes incomplete, and pinholes are generated.

  In addition, in the case of this known example, since there is no filling port zipper of the contents, it becomes about 1/2 of the bag width. Since the step is formed on the opening side, there is a problem that the appearance of the bag is deteriorated.

  The present invention is a pillow packaging bag in which there is a joint-attached part, and the zipper attachment method is completely improved so that pinholes are not generated, the discharge of contents is limited, and rapid filling is possible. The present invention provides a pillow packaging bag with a zipper that does not damage the outside of the bag and a method for producing the same.
