  In order to put beverages or the like in a bag, for example, to sell them in a store, it is preferable to form with a transparent resin sheet because the contents can be visually recognized and the cost for manufacturing the bag can be reduced. . However, a bag provided with a grip portion formed as a hole punched into an oval shape like a conventional bag can be manufactured at a low cost, but may have poor design properties, and is particularly put in the bag. Depending on the contents, it was difficult to make a high-quality back.

  An object of the present invention is to provide a high-quality resin sheet back.

  The resin sheet bag according to the present invention includes a first sheet and a second sheet that are arranged to face each other, and a first bent part and a second bent part that are bent to the opening side of the first sheet and the second sheet. A connection bottom portion connecting the first sheet and the second sheet on each bottom side of the first sheet and the second sheet, and an outer side surface of the second sheet by bending a side edge of the first sheet A joining side edge portion to be joined to the first sheet, the second sheet, the region where the first sheet and the second sheet overlap the first folded portion and the second folded portion, A string passing hole penetrating the first bent portion and the second bent portion is formed.

  According to the present invention, a high-quality resin sheet bag can be provided.

It is a front view of the state before passing a string through the back made from resin sheet concerning the embodiment of the present invention, and the contents are not contained. It is an expanded view of the back | bag made from a resin sheet which concerns on embodiment of this invention, and the surface visible in this figure becomes an inner surface. It is a front view of the state which put the contents in the back made from a resin sheet concerning the embodiment of the present invention. It is the top view which opened the opening part of the resin-sheet back which concerns on embodiment of this invention, and was seen from upper direction.

  Next, an embodiment of the present invention will be described based on the drawings. As shown in FIG. 1, the back 1 made of resin sheet is formed in a bag shape, and is formed in a substantially long rectangular shape with the vertical direction as the longitudinal direction when viewed from the front. In FIG. 1, the lower side of the resin sheet back 1 is the bottom and the upper side is the opening.

  The resin sheet back 1 is formed of a single sheet of transparent resin (specifically, polypropylene). The resin sheet back 1 is provided with a first sheet 10 having a substantially long rectangular shape on the front side. A second sheet 20 is disposed on the back side of the resin sheet back 1 so as to face the first sheet 10. The first sheet 10 and the second sheet 20 have the same outer shape.

  The first sheet 10 is formed with a joining side edge 30 that is folded from both side edges in the longitudinal direction and joined to the second sheet 20. Each joining side edge portion 30 is shortened in the short side direction so as to protrude laterally from the first sheet 10, and the length of the side 31 on the end side is longer than the length of the side 11 in the longitudinal direction of the first sheet 10. Is also shortened to form a substantially trapezoidal shape. In the joining of the joining side edge 30 and the second sheet 20, the inside of the joining side edge 30 (that is, the bag-like inner surface side of the resin sheet back 1) and the surface side of the second sheet 20 are adhesives or the like. It is performed by joining.

  The first sheet 10 and the second sheet 20 are connected to each bottom part of the first sheet 10 and the second sheet 20 by the connection bottom part 40. The connection bottom portion 40 is formed with a width direction smaller than the widths of the first sheet 10 and the second sheet 20. The connection side 41 with the first sheet 10 and the connection side 42 with the second sheet 20 at the connection bottom 40 are valley-folded when viewed from the inside of the back 1 made of resin sheet. Then, a side 43 that is mountain-folded parallel to the connection sides 41 and 42 is formed at a substantially intermediate position between the connection sides 41 and 42. 2, the valley fold is indicated by a one-dot chain line and the mountain fold is indicated by a two-dot chain line when viewed from the inner surface of the back 1 made of resin sheet.

  On the other hand, on the opening side of the first sheet 10 and the second sheet 20, there are a first bent part 50 and a second bent part 60 that have the same length in the width direction as the first sheet 10 and the second sheet 20, respectively. It is formed. Since the vertical direction is formed sufficiently shorter than the first sheet 10 and the second sheet 20, the first bent part 50 and the second bent part 60 have a long rectangular shape whose longitudinal direction is the width direction. The first bent portion 50 and the second bent portion 60 both have the same outer shape, are valley-folded at the connecting sides 51 and 61 with the first sheet 10 and the second sheet 20, and are made of resin sheet back 1. Placed inside.

  In the region where the first and second bent portions 50 and 60, and the first and second bent portions 50 and 60 of the first and second sheets 10 and 20 overlap, the first sheet 10 and the first A string passing hole 70 that penetrates the bent portion 50, the second bent portion 60, and the second sheet 20 in this order is formed in two places. Accordingly, for example, a hand strap can be formed by passing a single cord through the strap hole 70.

  As shown in FIG. 2, notches 52 and 62 are formed at both ends of the connection sides 51 and 61 of the first bent portion 50 and the second bent portion 60. The notches 52 and 62 are formed in the same R chamfered shape at the corners on the first sheet 10 and the first bent part 50 side and on the second sheet 20 and the second bent part 60 side, respectively. Yes. Thus, corners R are formed at both ends of the opening of the resin sheet back 1.

  When the beverage container 100 made of, for example, a bottle is put into the resin sheet bag 1 formed in this way, as shown in FIGS. 3 and 4, the connection bottom 40 that is folded in the side 43 is pushed downward, The folded connection bottom 40 is spread out. Then, the openings 45 formed on both sides of the connection bottom 40 are particularly widened in the front and back direction (up and down direction in FIG. 4). Here, the opening 45 is formed in a substantially triangular shape with the side 44 on both sides of the connection bottom 40 as the bottom. Then, as shown in FIG. 3, the resin sheet back 1 has an inverted trapezoidal shape in which the side on the opening side is shorter than the side on the bottom side in front view.

  Thus, since the back 1 made of a resin sheet has an inverted trapezoidal shape in front view when the contents are inserted, it can be easily given a high-class design. And since the back | bag 1 made from a resin sheet is provided with the string penetration hole 70, it can be set as the handbag using a string, and can make it easy to give a design with a high-class feeling. And since the string penetration hole 70 is penetrated in order of the 1st sheet | seat 10, the 1st bending part 50, the 2nd bending part 60, and the 2nd sheet | seat 20 from the front side, a string is passed over 4 sheets. And the strength of the string passing hole 70 can be increased.

Next, a method for manufacturing the resin sheet bag 1 will be described.
1st process: First, the resin sheet for back | bags shown in FIG. 2 of the state in which the string penetration hole 70 is not opened is prepared. That is, the resin sheet includes the first sheet 10, the second sheet 20, the joining side edge portion 30, the connection bottom portion 40, the first bent portion 50, the second bent portion 60, and the notch portion 52. , 62 are provided. As shown in FIG. 2, the first bent portion 50 extends from the opening side of the first sheet 10, and the second bent portion 60 extends from the opening side of the second sheet 20. Further, the joining side edge portion 30 extends from both side edges of the first sheet 10.

Second step: Next, each part is subjected to a predetermined bending process.
(1) When viewed from the inside of the resin sheet back 1, the side 11 in the longitudinal direction of the first sheet 10 is valley-folded.
(2) The connection sides 41 and 42 of the connection bottom 40 are folded in a valley, and the central side 43 is folded in a mountain.
(3) The connecting side 51 of the first sheet 10 and the connecting side 61 of the second sheet 20 are folded in a valley.
Note that any of the bending processes (1) to (3) may be performed first. Further, it is preferable that the side where the valley fold or the mountain fold is formed is provided with a crease at the stage of punching in the step of preparing the resin sheet in the first step.

  3rd process: Next, an adhesive agent is apply | coated to the inner surface of the joining side edge part 30, and the inner surface of the joining side edge part 30 and the outer surface of the 2nd sheet | seat 20 are joined.

  Fourth step: The string through hole 70 is formed by punching.

  Fifth step: A single string is passed through the string passing hole 70, and ends of the strings are connected to create a grip string.
