In particular, in this embodiment, a part of the lock 3 is exposed in a front view, and specifically, at least a part (protruding portion 47t) of the operating portion 47 of the lock 3 is located above the tip 2b of the cover 2. Since it is projected outward, it is possible to prevent the operability of the lock 3 from being deteriorated only by providing the cover C with a relatively small notch K corresponding to the protruding portion 47t.

Furthermore, a protrusion for pushing is provided at the lower portion of the cover 2 of the school bag R. In other words, the school bag R serves as a finger hook when locking the lock 3 on the outer surface of the front side of the cover 2. Since the cover plate 6 is provided, the front end surface of the bag cover C, that is, the portion corresponding to the notch K in bottom view is located at the widthwise position corresponding to the cover plate 6, as shown in FIG. The cover 2 is separated from the corresponding portion of the cover 2 in the thickness direction of the cover 2, and the operation of the operation portion 47 is not obstructed by the bag cover C.

In addition, since the bag cover C has the concave portion 7a formed at a portion located in the vicinity of the upper portion of the cover plate 6, it is conventional to urge the tip portion 21 of the cover 2 downward to perform the locking operation. It becomes possible to carry out in a similar manner. That is, the portion 7b between the concave portion 7a of the cover body 7 and the upper edge 6a of the cover plate 6 is steeper than the other portions, and therefore the tip of the cover 2 is covered by placing a finger on the steeply inclined portion 7b. The locking operation can be performed by urging 21 downward.

Further, the bag cover C includes a cover body 7 attached to the outer surface of the cover 2 and a backing portion 8 provided to form a pocket 9 on the inner surface side of the tip portion of the cover body 7. 9 is attached to the cover 2 with the tip 21 of the cover 2 inserted, and the cutout K is provided in the lower edge Ca thereof. Therefore, such a bag cover C is attached to the front lock type school bag R. However, there is no problem in the operation of the lock 3. In other words, according to the school bag R with the cover C of the present embodiment, despite the front lock type, even if the bag cover C that protects the outer surface of the cover 2 is attached, a problem occurs in the operation of the lock 3. Never.

The present invention is not limited to the embodiment described above.

For example, the present invention may be applied to bags other than school bags.

Further, in the above-described embodiment, a part of the operating portion is projected outside the tip of the cover, but the entire operating portion may be projected beyond the tip of the cover. Even in such a case, since the operation portion is provided at the tip and the operation portion is located outside the notch of the bag cover, there is no problem in the lock operation.

Further, in the above-described embodiment, the notch has a depth dimension that exposes only the distal end portion of the operating portion, but a notch having a depth dimension that exposes the entire operating portion is provided. Of course good.

In addition, various modifications may be made without departing from the spirit of the present invention.
