Description

This invention relates to a travel bag, and more particularly to a travel bag with an easy-to-use zipper. Figure 1 is a cross-sectional view of a conventional travel bag 1. The travel bag 1 comprises a box body 2, a lid 3, and a zipper 4. The box body 2 has an opening 5 and a first convex edge portion 6 extending vertically. The lid 3 is located outside the box body 2 and has a second convex edge portion 7 extending horizontally. The zipper 4 is sewn separately to the first convex edge portion 6 and the second convex edge portion 7 on opposite sides. The sewing process involves connecting one side of the zipper 4 to the first convex edge portion 6, and then folding the zipper 4 to connect the other side to the second convex edge portion 7. In other words, not only is the installation of the zipper 4 time-consuming, but it is also difficult to straighten and connect the zipper 4 to the first convex edge portion 6 and the second convex edge portion 7, indicating room for improvement. This is a cross-sectional view showing a portion of a conventional travel bag.This is a perspective view showing a travel bag according to the first embodiment of the present invention.This is a side view showing a travel bag according to the first embodiment of the present invention.This is an exploded perspective view showing a travel bag according to the first embodiment of the present invention.This is an enlarged view showing a zipper connecting member of a travel bag according to the first embodiment of the present invention.This is a cross-sectional view showing a zipper and annular sleeve of a travel bag according to a first embodiment of the present invention.This is a cross-sectional view along line 7-7 in Figure 3.This is a cross-sectional view showing a portion of a travel bag according to a second embodiment of the present invention.This is a perspective view showing a travel bag according to a third embodiment of the present invention.This is an exploded perspective view showing a travel bag according to a third embodiment of the present invention.This is a portion of a cross-sectional view of a travel bag according to the third embodiment of the present invention, as seen from the side. The present invention will be described below with reference to the drawings. In this specification, directional terms such as up/down, left/right, top, bottom, inside, and outside are expressed based on their usual usage. (First Embodiment) As shown in Figures 2 to 4, the travel bag 1 according to the first embodiment of the present invention comprises a box body 10, a zipper connecting member 20, a zipper 30, and a lid 40. The box body 10 is composed of a first shell 11 and a second shell 12 that join together, and has a first connecting part 15, four casters 17, and a pull handle 18. The first shell 11 has a first side wall 111 and a first ring wall 112. The first side wall 111 is connected by being surrounded by the first ring wall 112. The second shell 12 has a second side wall 121 and a second ring wall 122. The second side wall 121 is connected by being surrounded by the second ring wall 122. The first side wall 111 and the second side wall 121 are arranged relative to each other. The first side wall 111, the first ring wall 112, the second ring wall 122, and the second side wall 121 constitute a storage space 13 for storing luggage. The first side wall 111 has an opening 14.
