<About packaging bags>
A packaging bag 1 according to the present embodiment will be described with reference to FIGS. In the present embodiment, the direction indicated by the arrow A1 in FIG. 1 is referred to as the vertical direction, and the direction indicated by the arrow A2 is referred to as the lateral width direction.

  The packaging bag 1 according to the present embodiment is a bag made of a synthetic resin film. The packaging bag 1 is substantially entirely composed of a synthetic resin film. As the synthetic resin, various materials can be used, but polyethylene and polypropylene are mainly used.

  The packaging bag 1 includes a bag body 2 that can accommodate the contents therein. The bag body 2 has, for example, a rectangular shape in plan view and includes four corner portions 23. The bag body 2 is, for example, a two-sided bag, and has a storage portion 21 formed by folding a single synthetic resin film at the lower portion and crimping both ends in the width direction by heat, ultrasonic waves, or the like. A header portion 22 having a hole used in the hanging display of products may be provided on the upper portion of the storage portion 21.

  In addition, the shape of the bag body 2 is not limited to this embodiment, For example, a fusing bag, a back sticking bag, a three-sided bag, etc. may be sufficient. Further, the contents are not limited to small ones that are generally concerned about accidental ingestion and accidental eating such as button-type batteries and earrings, and the size of the bag body 2 is not limited.

  The bag body 2 has a pattern 3, for example. The pattern 3 is a concept including characters, figures, symbols, colors, pictures, or a combination thereof. In addition, in this Embodiment, although the pattern 3 has illustrated the flower illustratively, various patterns are attached | subjected according to the accommodation.

  On the outer surface of the bag body 2, a bittering agent 4 having a pattern with a certain thickness is printed. As the bitter agent 4, for example, a substance that feels bitter or irritating when a human or an animal puts it in the mouth and does not harm the mouth is used. The bitter agent 4 is printed by gravure printing mentioned later, for example. Thereby, the bitter agent 4 is formed in the pattern of fixed thickness. Here, the constant thickness pattern means that the pattern is formed with a uniform thickness.

  In the present embodiment, the bitter agent 4 is printed on the pattern 3. If the bitter agent 4 is printed on the outer surface of the bag body 2, it may be printed on the entire outer surface of the bag body 2 or may be printed partially. Further, the bitter agent 4 may be printed on a portion other than the pattern 3.

  The bitter agent 4 may have a color. Specifically, the bitter agent 4 has a color by mixing ink with a medium or a solvent, and has the same function as the ink. Thereby, the bitter agent 4 can constitute a part of the pattern 3. For example, when the pattern 3 is a flower as in the present embodiment, the bitter agent 4 may be printed on only one petal.

  The bitter agent 4 may be printed on the corner 23 of the bag body 2. Specifically, as shown by the hatching in FIG. 2, for example, the bitter agent 4 may be printed only in the corner region 23 a divided into a substantially fan shape or a substantially rectangular shape including the corner portion 23.

  Further, as shown by the broken line in FIG. 2, the bitter agent 4 includes both upper and lower end regions 24 a including the upper and lower end portions 24 of the bag body 2, or both lateral end portion regions including the both lateral end portions 25 of the bag body 2. It may be printed only on 25a.

  Children and pets have the habit of putting them in their mouths from narrow or end portions. By printing the bittering agent 4 on the regions 23a, 24a, and 25a of the bag body 2, children and pets feel the bitterness at the moment when the packaging bag 1 is put in their mouths. Can be prevented. Moreover, since it is sufficient to print the bittering agent 4 not on the entire outer surface of the bag body 2 but only on a part of the bag body 2, the area for printing the bittering agent 4 can be reduced, and the printing amount of the bittering agent 4 can be reduced. This can reduce the cost.

  The thickness of the bitter agent 4 is preferably 0.4 μm to 2 μm, for example. As described above, since the both ends 25 in the width direction of the bag body 2 are fixed by thermocompression bonding, when the bitter agent 4 is printed in the width both end region 25a of the bag body 2, it is printed in other portions. It is desirable to print thicker. Thereby, especially when thermocompression bonding is performed, it is possible to prevent the bitter agent 4 from being completely volatilized.

  Below, the manufacturing method of the packaging bag 1 is demonstrated in detail.
