Abstract: A suitcase structure includes a case portion having a case opening and provided with a case-side recess; a cover portion pivotally connected to the case portion to selectively close or open the case opening and provided on a cover-side transitional edge portion and a cover sidewall thereof with a cover-side recess located corresponding to the case-side recess; a latch pivotally connected to the case portion and having an end receivable in the case-side recess and another end receivable in the cover-side recess; and a retainer for retaining the other end of the latch thereto. Therefore, the latch can be located in the case-side and the cover-side recess at the same time to be flush with outer surfaces of the case portion and cover-side transitional edge portion. Therefore, the latch is avoided from colliding with external object and separating from the suitcase structure when the latter is pulled to move around.

Abstract: A snap-fit cooler box includes an outer shell, an inner shell, a plurality of inner snap-fit components, a plurality of outer snap-fit components, an insulating material and a cover. A closing end and an opening end are respectively formed on opposite sides of the outer shell; a container and a connecting flange are disposed on the inner shell. The inner snap-fit components are disposed between the closing end and the container, the outer snap-fit components are disposed between the opening end and the connecting flange. The inner and outer snap-fit components are used for allowing the inner shell to snap into the outer shell without using screws or nails. Therefore, the inner shell will not leak internal water to the exterior of the outer shell.

Abstract: A luggage of the present invention includes a case body and a cover plate. A communication opening forms on one side of the case to communicate with the interior of the case, and the case is provided with a main zipper chain around the communication opening. Opposite sides of the cover are respectively set as an outer surface and a inner surface, and the outer surface and the inner surface are respectively provided with subordinate zipper chains. Wherein, the main zipper chain can selectively meshes with one of the subordinate zipper chains to make the outer surface exposed outside the case, or meshes with the other subordinate zipper chain to expose the inner surface outside an accommodating space. Through it, a connection assembly allows the cover plate to be connected to or separated from the case body through different connection ways which enhancing the diversity of the appearance of the luggage.

Abstract: The luggage of the present invention comprises: two outer shells, a joint piece and a removable liner. Each shell has a closed end and an opening end. Wherein the joint piece connects to one of the opening ends, so that the joint piece covers a partial area of the opening end, and then the remaining area of the opening end not covered by the joint piece is configured as a through opening. In addition, the removable liner is hollow, and is located inside the outer shell attached with the joint piece, thus removable liner can be selectively assembled to or separated from the joint piece. Therefore, when separated from the joint piece through the detaching-assembling set, the removable liner can be used separately as a handbag or a backpack, and even replaced with another removable liner with different appearance, which makes the internal shape of the luggage more diverse.
