  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a front view showing the configuration of the resin packaging bag 1.

  The resin packaging bag 1 is made of a resin film such as a translucent polyethylene film and has a top opening 2, a seal bottom 3, and a gusset portion 4. A linear fusion part 8 extending over the entire width of the bag 1 is formed in the seal bottom part 3 by a heat seal device (not shown).

  2 and 3 are perspective views schematically showing how the bag 1 is folded.

  As shown in FIGS. 2A and 2B, the bag 1 is folded in half with respect to the width direction axis X1-X1. A large number of bags 1 (about 10 bags 1 in this example) folded in two at the first folded portion 6 are stacked in the same direction as shown in FIG. As shown in FIGS. 3 (A) and 3 (B), the bags 1 stacked in multiple layers are further folded about the width direction axis X2-X2, and the second folded portion 7 is formed. In the laminated body 5 of the bag 1 formed in this way, the first folded portion 6 is vertically arranged at one edge portion, and the second folded portion 7 is disposed at the opposite edge portion.

  FIG. 4 is a cross-sectional view conceptually showing the folding process of the bag 1 shown in FIGS. 4 (A) and 4 (B) similarly show the folding process shown in FIGS. 2 (A) and 2 (B). 4 (C) and 4 (D) similarly show the folding process shown in FIGS. 3 (A) and 3 (B). In order to simplify the illustration, the process of stacking and folding the three bags 1 is shown in FIGS. 4 (C) and 4 (D). In this embodiment, about 10 bags are used as described above. 1 is stacked.

  As shown in FIG. 4D, in the bag 1 folded in four, the first folded portion 6 is located on one side (upper side) and the opening 2 on the opposite side (lower side). And the seal bottom 3 is located. The seal bottom 3 is located on the inner side (upper side) of the opening 2.

  FIG. 5 is a plan view, a cross-sectional view taken along a line II, and a cross-sectional view taken along a line II-II, showing a portable unit in which the laminated body 5 of the bags 1 folded in this way is housed in a plastic portable bag 10. FIG. 6 is a plan view showing the structure of the linear opening means (perforation).

  As the portable bag 10, a transparent or translucent resin film packaging material having the same specifications as the pocket tissue portable bag can be used. The portable bag 10 is made of an annular film 11 having both end portions 16 sealed by the heat seal portion 12, and has a linear opening means 20 that forms an opening for sequentially pulling out the bag 1 as the contents from the portable bag 10. The linear opening means 20 is a perforation similar to the pocket tissue portable bag, and can be easily broken and opened with fingers. The linear opening means 20 forms a slit-shaped opening in the portable bag 10 by cutting perforations. Termination means 21 is provided at both ends of the linear opening means 20 for preventing cracks from extending further from both ends of the slit-shaped opening. The termination | terminus means 21 consists of a semicircular cut as shown in FIG.

  FIG. 7 shows a modification of the termination means 21.

  As shown in FIG. 7, it is also possible to form a circular opening at both ends of the linear opening means 20 as the termination means 21 ′. However, when the termination means 21 ′ having such a configuration is adopted, it is necessary to dispose of the punching material of the resin film that is generated when the circular opening is punched. It is desirable to employ a semicircular cut (termination means 21) as shown.

  As shown in FIG. 5 (A), the linear opening means 20 is not located at the center of the portable bag 10 but at a position unevenly distributed on one side, and the edge where the second folded portion 7 of the laminate 5 is arranged. Positioned close to the part. This is a point in which the linear opening means is greatly different from the pocket tissue portable bag disposed at the center of the portable bag.

  Here, in the industry, attempts have been made for many years to carry a resin packaging bag in a portable bag similar to a portable bag for pocket tissue. However, none of these past attempts were successful and could not be commercialized. This is because when a packaging bag is pulled out of a portable bag, a plurality of packaging bags are connected and pulled out, or a large number of packaging bags are pulled out from the opening together, making it impossible to pull out the bags one by one. This is because. For this reason, it has been considered impossible to wrap a resin packaging bag in a form like a pocket tissue and make it portable.

  This point will be further described with reference to FIGS.

  FIG. 8 is a cross-sectional view conceptually showing the configuration of the mobile unit shown in FIG. 5, and FIG. 9 is a cross-sectional view showing a state in which the bag 1 is pulled out from the mobile unit shown in FIG. In FIG. 8, only the cross section of the bag 1 located in the outermost layer of the laminated body 5 is shown by a solid line, and the other laminated portions of the bag 1 are entirely shown by hatched cross sections. Moreover, the portable bag 10 is shown with the virtual line (dashed-dotted line).

  8 and 9 show a state in which the linear opening means 20 is opened and a slit-shaped opening 30 for pulling out the bag is formed on the upper surface of the portable bag 10. As shown in FIGS. 8A, 8B, and 9, the outermost-layer bag 1 can be pulled out from the slit-shaped opening 30 to the outside of the portable bag 10 with fingers. As shown in FIGS. 8B and 8C, the first folded portion 6, the opening 2 and the seal bottom 3 of the bag 1 move along the upper and lower surfaces of the laminate 5, and the bag 1 , Is smoothly drawn out from the slit-shaped opening 30.

  FIG. 10 is a cross-sectional view showing, as a comparative example, the configuration of a portable unit in which the linear opening means 20 is arranged at the center of the portable bag 10.

  10 (A) and 10 (B), when the outermost layer bag 1 is to be pulled out of the portable bag 10 with the fingers from the slit-shaped opening 30, as shown by the arrow in FIG. 10 (C), The inward and upward pressure P acts on the second folded portion 7, and the second folded portion 7 is deformed. For this reason, the bag 1 cannot be pulled out smoothly from the slit-shaped opening 30. This is considered to be because the movement resistance of the lower portion of the bag 1 is relatively large and the opening 2 and the seal bottom 3 do not move smoothly in the direction of the arrow.

  That is, in the portable bag 10 shown in FIG. 5, if the linear opening means 20 is disposed at the center of the portable bag 10, if only one bag 1 in the portable bag 10 is pulled out, the laminate 5 is deformed. As a result, a plurality of bags 1 are connected and pulled out, or all the bags 1 of the laminated body 5 are pulled out together.

  On the other hand, as shown in FIG. 5A, when the linear opening means 20 is unevenly distributed at a position close to the folded portion 6 of the laminated body 5, as shown in FIGS. Can be pulled out one by one.

The dimension etc. of the laminated body 5, the portable bag 10, and the linear opening means 20 which are shown in FIG. 5 are as follows.
Width D of portable bag 10 = 105 mm
Length L of portable bag 10 = 155 mm
The width d of the laminate 5 is 85 mm.
The length of the laminated body 5 (width of the bag 1) w = 126 mm
Linear opening means 20 (perforation) length W = 91 mm
Termination means 21 (semicircular cutout) diameter R = 5 mm
Distance (dimensions) from side edge 15 of portable bag 10 to opening means 20 T = 15 mm
Distance (dimensions) from the edge 16 of the portable bag 10 to the opening means 20 S = 32 mm
Perforation notch 25 length J = 6mm
Length of perforated connection 26 K = 2 mm

  The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above-described embodiments, and various modifications or changes can be made within the scope of the present invention described in the claims. Is possible.

  For example, in the above embodiment, as the linear opening means 20, a perforation that can be easily broken by fingers is adopted, but the slit opening is sealed by a sealing means such as an adhesive tape that can be peeled relatively easily. The opening structure may be adopted as the linear opening means 20.

  Moreover, in the said Example, although the 1st folding | turning part 6 is arrange | positioned on the surface of the laminated body 5 located in the same side (upper side) as the surface of the portable bag 10 in which the opening 30 was formed, the 1st folding | turning part 6 May be arranged on the opposite side (lower side) of the opening 30. However, when the arrangement of each part of the laminated body 5 is set in this way, the opening 2 and the seal bottom 3 located on the same side (upper side) as the opening 30 are separated or separated when pulled out, and are the same as the comparative example shown in FIG. Since the inner and upper pressure P tends to act on the second folded portion 7 and the second folded portion 7 tends to be deformed, special attention is required for setting the dimensions and arrangement of the respective portions.

  According to the present invention, there is provided a portable unit in which a large number of resin packaging bags are packaged in a compact manner, and the resin packaging bags can be taken out from the package one by one in use. Can be provided.
