  • the height L3 is, for example, approximately 15 mm.
  • the heights L2 and L3 are not limited to this.
  • the lid section 173 when the storage section 17 is in its normal state (for example, when the bag 10 is slung over the shoulder or held in the hand), the lid section 173 is positioned forward of the front section 171 and can cover the opening 17s. This prevents the storage space of the storage section 17 from being exposed to the outside air, and prevents the stored item G1 from getting wet in the rain or dirty with dust.
  • the left end 173a and the right end 173b of the lid portion 173 are fixed to the bag body 1 together with the front portion 171 in a state where they overlap with each other, so that when the storage portion 17 is in its normal state, the opening 17s can be maintained in a closed position (closed position).

  • Figures 13 and 14 show an example of how the bag 10 is used. Specifically, Figures 13 and 14 show a state in which an item G1 (e.g., a laptop computer) is stored in the storage section 17 of the bag 10. Figure 13 shows a state in which the user is holding the bag 10, and Figure 14 shows a state in which the user has opened the opening 14 of the bag 10. Figure 15 shows an enlarged view of the A3 portion of Figure 14.
  • G1 e.g., a laptop computer
  • the center portion of the lid 173 bends in the D5 direction, and the portion of the lid 173 that overlaps with the front 171 (overlap portion) comes off the front 171, and the opening 17s becomes exposed (open position). In this way, when the user unfolds the bag 10, the opening 17s of the storage section 17 changes to the open position.
  • the storage section 17 contains an item G1
  • the storage space is easily maintained by the item G1 so the front portion 171 of the storage section 17 is not pulled in the D5 direction or bent in the D5 direction, and therefore, when the bag body 1 is unfolded as shown in FIG. 14, the opening portion 17s easily changes to an open position.
  • the opening 17s changes to a closed position as shown in FIG. 13.
  • the opening 17s when the opening 17s is in the open position, only the end of the front part 171 and the end of the lid part 173 overlap, so that forces in opposite directions are applied to the front part 171 and the lid part 173 at the overlap part R1. That is, a force in the D5 direction is applied from the lid part 173 to the overlap part R1 of the front part 171, and a force in the D6 direction is applied from the front part 171 to the overlap part R1 of the lid part 173.
  • the storage section 17 changes to a closed position when the user closes the opening 14 of the bag 10 (see FIG. 13), and changes to an open position when the user opens the opening 14 of the bag 10 (see FIG. 14).
  • the storage section 17 has a function that enables it to change its position between the open position and the closed position in response to the opening and closing action of the bag 10 by the user. This allows the user to easily put items in and take items out of the storage section 17.
  • the storage section 17 is provided with cushions C1, C2 on the front section 171 and the rear section 172.
  • the rear section 172 is pulled in the direction D5, but since the front section 171 is not fixed to the rear section 12 of the bag body 1 and the elastic force of the cushion C1 acts on it, the front section 171 tries to maintain a flat state. This makes it easier for the opening 17s to change to an open position.
  • the cushions C1 and C2 exert a force that causes them to return to their original state (flat state) due to their own elasticity. Therefore, when the user closes the opening 14 of the bag 10 (see FIG. 13), the elasticity of the cushions C1 and C2 makes it easier for the front portion 171 and rear portion 172 to return to their normal flat state. This makes it easier for the opening 17s to change from an open position to a closed position. Therefore, by providing the cushions C1 and C2, it becomes possible to more easily change the position between the open position and the closed position in response to the opening and closing action of the bag 10 by the user. This makes it easier to put in and take out items.
  • the bag 10 has a configuration in which the width W1 (frontage in the left-right direction) of the opening 17s of the storage section 17 is wider than the interval W2 between the attachment positions of the handle 2 on the bag body 1 (W1>W2).
  • W1 frontage in the left-right direction
  • W2 interval between the attachment positions of the handle 2 on the bag body 1 (W1>W2).
  • the width W1 of the opening 17s is narrower than the distance W2 between the attachment positions of the handles 2 (W1 ⁇ W2), the force acts outside the width of the lid 173, and when the user opens the opening 14 of the bag 10, the entire lid 173 is pulled in the direction D5, making it difficult to change to the open position.
  • the bag 10 according to the first embodiment has, for example, W1 of approximately 290 mm and W2 of approximately 160 mm. W1 and W2 are not limited to these values and are determined appropriately according to the overall size of the bag 10.
  • the bag 10 has a configuration in which the lid portion 173 of the storage section 17 is located above the bag body 1.
  • the lid portion 173 is located close to the reinforcing portion 1a provided at the upper end of the bag body 1.
  • the upper end of the bag body 1 widens greatly, as shown in FIG. 14, for example. That is, the opening width in the front-rear direction of the bag body 1 increases from the bottom to the top. Therefore, when the lid portion 173 is located above the bag body 1, the force pulling in the D5 direction is greater than when the lid portion 173 is located below the bag body 1.
  • the opening 17s is more likely to change to the open position than when the lid portion 173 is located below the bag body 1. Also, when the user closes the opening 14 of the bag 10, the lid portion 173 is similarly pushed by a large force in the D1 direction (see FIG. 13), so the opening 17s is more likely to change to the closed position. Therefore, by adopting the above-described configuration, it becomes possible to more easily change the position of the bag 10 between the open position and the closed position in response to the opening and closing action of the user, making it easier to put in and take out items.
