Both ends of the insertion line 60 are curved away from the end 16a.

  Next, an example of an assembling method of the packaging bag 10 of this embodiment will be described. Here, FIG. 2 is a view of the front side of the bag forming piece 12 of the packaging bag 10, in which the folding method in which the front surface of the bag forming piece 12 is convex, and the folding method in which the back surface is convex. Is referred to as reverse folding.

  First, the bottom support piece 40 is folded forward at the folding line 42 and overlapped on the back surface of the side surface 14, and the bottom plate 54 is folded forward at the folding line 56 and overlapped on the back surface of the side surface 16. FIG. 3 shows the bag forming piece 12 in this state as viewed from the back. Next, the glue 62 is applied to a portion of the surface of the bottom support piece 40 closer to the tip end than the fold line 44, the glue 64 is applied to the back surface of the glued piece 20, and the fold line 18 is folded forward. The back surfaces of the side surfaces 14 and 16 are overlapped with each other, the fold line 22 is folded forward, and the glued piece 20 is glued to the surface of the side surface 14 with the glue 64. At this time, the folded back surface of the bottom support piece 40 is glued to the surface of the bottom plate 54 by the glue 62. This results in a folded state as shown in FIG.

  Next, the crease lines 18 and 22 are pushed closer to bend the side surfaces 14 and 16 away from each other to form a cylindrical body to form an inner space, and a hand is inserted through the outlet 68 on the end 16a side of the inner space. The bottom plate 54 is spread apart from the side surface 16 and the crease line 56 is folded forward at 90 °, and the bottom plate 54 is positioned substantially perpendicular to the side surface 16. At this time, the bottom support piece 40 glued to the bottom plate 54 is also raised from the side surface 14, the crease line 42 is correctly folded at 90 °, and the crease line 44 is correctly folded to hold the bottom plate 54. As a result, the bottom of the packaging bag 10 is formed, and the packaging bag 10 has a thickness on the lower side and gradually loses the thickness on the upper side, and the side surface 14 and the side surface 16 are aligned without any gap at the outlet 68 on the end 16a side. Have been.

  Next, when using the packaging bag 10, a container 66 such as a medicine is put into the space inside the packaging bag 10 from the outlet 68. Then, as shown in FIG. 5, the pair of fold lines 38 is forward-folded, and the spring piece 36 is overlapped on the back surface of the locking piece 30. Since the pair of spring pieces 36 are formed slightly shorter than half the length of the locking piece 30, they do not overlap with each other. Next, as shown in FIG. 6, the folding line 32 is folded forward and the locking piece 30 is overlapped on the back surface of the insertion portion 28. At this time, the spring piece 36 is folded between the locking piece 30 and the insertion part 28, and the locking piece 30 is urged by the spring piece 36 to open from the insertion part 28.

  Thereafter, while holding the locking piece 30 with a finger so as not to open from the insertion portion 28, the crease line 26 is folded forward and the lid piece 24 is folded on the surface of the side surface 16. Into the insertion line 60. The locking piece 30 is urged away from the insertion part 28 by a spring piece 36, but the tip of the pair of abutting parts 34 located at both ends of the locking piece 30 abuts on the surface of the side surface 16. Due to the contact, the locking piece 30 bends so that the central portion is separated from the insertion portion 28. The side surface 16 has an insertion portion 28 pressed against the back surface below the insertion line 60, that is, a portion near the bottom plate 54, and a locking piece 30 above the insertion line 60, that is, a portion near the outlet 68. Is pressed against the surface. When the insertion portion 28 is inserted further deeply, and the end portion 30a of the locking piece 30 passes through the insertion line 60 on the side surface 16, the end portion 30a is resiliently clicked to generate a cut end surface of the insertion line 60. After passing through 60a, it opens from the insertion portion 28 and projects into the inner space. In this state, as shown in FIG. 8A, the most protruding portion of the arc of the end portion 30a of the locking piece 30 projects on the back surface of the side surface 16, and the other portion of the end portion 30a is , Which faces the cut end surface 60 a of the insertion line 60 of the side surface 16 and continues to the contact portion 34 which comes into contact with the surface of the side surface 16. Thereby, the packaging by the packaging bag 10 is completed as shown in FIG. At this time, the locking piece 30 is locked on the upper side of the insertion wire 60, the insertion part 28 and the locking piece 30 cannot be pulled out from the insertion wire 60, and there is a child resistant effect, and It is possible to prevent the contents 66 from being taken out and accidentally swallowed.

  When the user takes out the contents 66 from the packaging bag 10, as shown in FIG. 8B, the user pushes the guide piece 50 on the side surface 14 from outside. Then, the guide piece 50 is separated from the side surface 14 by being separated by the cutting line 48, and a portion between the end portions 48 a of the cutting line 48, that is, a portion where the cutting line 48 is interrupted becomes a base end portion continuous with the side surface 14, and a distal end portion is formed. In a cantilevered state, it becomes movable from the side surface 14, and the tip portion is pressed against the side surface 16. The arc-shaped most protruding portion of the end portion 30a of the locking piece 30 projects over the back surface of the side surface 16, but is pushed by the guide piece 50 and passes through the cut end surface 60a of the insertion line 60. And is pushed out to the front side of the side surface 16 and closed by the insertion portion 28 to release the locking. When the guide piece 50 pushes the end 30 a of the locking piece 30, the guide piece 50 passes through the cut end face 60 a of the insertion wire 60 while elastically deforming, generates a clicking sound, and comes into contact with the surface of the side surface 16. . Therefore, the vicinity of the end 30a of the locking piece 30 is prevented from being inserted again into the insertion line 60 and locked.

  Then, as shown in FIG. 8C, the insertion portion 28 is pulled out from the insertion line 60, and the lid piece 24 is opened. When the insertion portion 28 is pulled out from the insertion wire 60, the locking piece 30 can be smoothly moved while rubbing the guide piece 50. By the above operation, the contents 66 can be taken out from the opened outlet 68 and taken. After use, the guide piece 50 is removed from the surface of the side surface 16 and returned to be flush with the side surface 14 by, for example, bending the side surface 14 and the side surface 16 away from each other. The cover piece 24 is normally folded along the crease line 26 while covering the outlet 68, and the spring piece 36, the locking piece 30, and the insertion portion 28 are folded in the above-described manner, and inserted into the insertion line 60. It is locked by 30 and has a child resistant function and is locked.

Furthermore, the packaging bag 10 is securely locked by the elasticity of the bag body forming piece 12, and the locking is released by a simple operation of pressing the guide piece 50, so that the operation is easy for the user. It is not necessary to individually package the container 66 with a child resistant function, and it can correspond to many containers 66 regardless of the shape. For example, various agents such as PTP, sachets, drug solution bottles, tubes, etc. Drugs in the form can be put together. Further, a medicine prescribed at the pharmacy may be put together with the medicine bag, and the container 66 may be other than the medicine. In addition, various articles that require careful handling, such as blades and lighters, may be used.

  Since the bag-forming piece 12 is made of a material having an appropriate elasticity such as a polyester-based synthetic resin, the bag-forming piece 12 can be securely locked, can be securely resealed, and can be used repeatedly. . Since it is made of synthetic resin, it is durable, and the elasticity of the spring piece 36 does not weaken. Further, when made of opaque synthetic resin, the container 66 accommodated in the inner space is not seen, so that it is devised so as not to attract children's interest.
