It is assumed that the tearing portions 4 are formed. Each of the tearing-up portions 4 has a substantially semicircular shape in the illustrated example, but may be a notch having an arbitrary shape such as a triangular shape or a linear shape.

  In the continuous bag of the present invention, each upper belt-like portion 1a between each fastener portion 1c and each handbag portion 3 is formed as a thin film in order to easily separate each handbag portion 3. Further, each upper strip 1a is provided with a linear groove d having a substantially V-shaped cross section between a plurality of linear projections p provided on the inner surface, and any one of these linear grooves d. By cutting along the bottom of the groove, each hand-held portion 3 can be easily separated.

  It is preferable that the thin-film-formed portion of each upper belt-like portion 1a and the portion provided with the linear groove d are connected to the tear-up portions 4 because the hand-holding portions 3 can be easily separated. Further, instead of assuming that each upper strip 1a is formed as a thin film or that each upper strip 1a is provided with a linear groove d, the front and back sheet fabrics 2A and 2B corresponding to these portions are perforated. Alternatively, a weak line (not shown) may be provided. Similarly, it is preferable that the perforation and the weak line are connected to the tearing-up portion 4.

  In the continuous bag body of the present invention, each of the bag bodies 2 is formed with symmetrical recesses 5 formed by fusing these sheet fabrics on both sides of the front sheet fabric 2A and the back sheet fabric 2B in the vicinity of the bottom. Yes. This recess 5 separates each bag 2 into a storage bag, and in a sealed state in which contents such as granular materials are stored, as shown in FIG. 7, the weight of the stored contents is used as a front sheet. Both sides of the fabric 2A and the back sheet fabric 2B are bent outward, the bottom of the storage bag is expanded, and the storage bag can be made independent.

  Furthermore, in the continuous bag body of the present invention, each bag body 2 is provided with a cut line 6 for forming a bottom part separation port for separation in the bag width direction at the bottom part. These tear lines 6 can be weak lines, perforations, and the like. The tear lines 6 are cut by the tear lines 6 and separated into the respective bag bodies 2, and the contents are stored from the bottom separation ports formed in the respective bag bodies 2. After that, the bottom separation port is side-sealed.

  The continuous bag of the present invention may be separated into each bag 2 as described above and commercialized as a storage bag described below. However, when the contents are packed in an automatic weighing / packaging machine. Can be made into a product by winding it into a roll without being separated into each bag 2.

  Next, the storage bag of the present invention has substantially the same structure as that obtained by separating the continuous bag body into each bag body 2 and is prepared by separating the continuous bag body into each bag body 2. However, it goes without saying that the continuous bags may be created one by one without being separated into the respective bags 2 as described above.

  Therefore, the storage bag of the present invention has many parts overlapping with the description of the continuous bag body described above, but hereinafter, a mode for carrying out the storage bag of the present invention will be described in the same manner.

  As shown in FIG. 4, the storage bag according to the present invention has the opening and closing fastener 1 in the width direction on the inner surfaces of the front sheet 2a and the back sheet 2b constituting the bag body 2 with the bottom portion unsealed.

The opening / closing fastener 1 is formed by fusing each of an upper belt-like portion 1a and a lower belt-like portion 1b described later as a fusion region over the entire width direction on the inner surfaces of the front sheet 2a and the back sheet 2b. As other fusion regions, at least the widthwise portions of the lower belt-like portion 1b (for example, equal width regions in the width direction excluding the two side ends that are the fusion end portions of the front sheet and the back sheet) Both sides of the one in which only the facing surface part is fused, or the widthwise large part of the upper belt-like part 1a (for example, the equal width area in the width direction excluding the two side edges that are the fused ends of the front sheet and the back sheet) Only the surface facing the surface may be fused.

  The opening / closing fastener 1 has a pair of upper belt-like portions 1a and a pair of lower belt-like portions 1b, and has a pair of fastener portions 1c that are detachable from each other between the upper and lower belt-like portions 1a, 1b. A plurality of linear protrusions p are provided on the inner surfaces of the upper and lower belt-like portions 1a and 1b, respectively, and the strength of the upper and lower belt-like portions 1a and 1b is enhanced by these linear protrusions p. Further, the upper end of the upper strip 1a is formed by fusing the linear projections p, and the upper end of the upper strip 1a is not separated, but the linear projections p are fused. You may or may not do it. In addition, the fastener portion 1c is a combination of a single female portion and a male portion that can be freely engaged and disengaged, but a combination of a plurality of female portions and a male portion that can be freely engaged and disengaged. Or other forms.

  The front sheet 2a and the back sheet 2b constituting the bag body 2 are configured by overlapping two sheets and fusing both sides as shown in the figure, but the tube-shaped sheet is flattened. It may be configured as described above.
