Abstract: A snap-fit suitcase includes two shell structures respectively having a case member removably snap-fitted onto a frame member; two lining structures respectively being removably snap-fitted onto the frame members and located in the case members; and a zipper structure having two zipper tapes and a slider. The zipper tapes respectively include a plurality of embedding teeth, which are embedded in the frame members; and the slider is used to close a plurality of closure teeth on one zipper tape to a plurality of closure teeth on the other zipper tape. With these arrangements, both the case members and the lining structures can be snap-fitted onto the frame members to not only largely shorten the time for assembling the suitcase, but also enable easy disassembling of the case members, the frame member and the lining structures to facilitate convenient repair and maintenance of the suitcase.

Abstract: The present invention provides a structure for quickly assembling a handle of a draw-bar case. The structure includes a case body and several handle assemblies. The handle assembly includes a handle and two handle retaining brackets. The handle retaining bracket are provided with a first inclined surface and a second inclined surface. The first inclined surface and the second inclined surface are provided with a position-limiting slot. The case body is provided with a clamping groove that is disposed corresponding to the handle retaining bracket. Two opposite side walls of the clamping groove are provided with an inverted buckle. The handle retaining bracket is aligned with and pressed into the clamping groove. The first and the second inclined surface will be adjacent to the inverted buckles, until the inverted buckles on both sides of the clamping groove are snap-fitted onto the position-limiting slots on both sides of the handle retaining bracket respectively.

With the above arrangements, the trolley case can be easily and efficiently assembled.

Abstract: The present invention provides a structure for assembling a snap-on caster of a draw-bar case. The draw-bar case includes a case body and four caster assemblies. The caster assembly includes a caster and an upper positioning cover. The caster includes a mounting pedestal and a universal wheel. Four sides of the case body are each provided with an installation slot. Several insertion plates are disposed on an inner side surface of the upper positioning cover. The installation slot is penetrated to form a through hole that is disposed corresponding to the insertion plate. The installation pedestal is provided with a buckle plate that is disposed corresponding to the through hole. The buckle plate is penetrated to form an insertion hole. Both sides of one end of the insertion plate are each provided with an inverted buckle. The insertion plate is snap-fitted onto the insertion hole after passing through the through hole and the insertion hole sequentially.

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.

Abstract: A cooler box includes a body portion and a cover portion pivotally turnably connected to each other via a hinge structure. The body portion has a storage opening and internally defines a storage space communicable with the storage opening; and includes, from an outer to an inner side, an outer shell, an insulation layer and an inner shell. The body portion further includes a binding frame assembled to an upper end thereof. The binding frame includes two substantially parallelly extended clamping wall portions, which together inwardly clamp on the outer shell, the insulation layer and the inner shell, such that the insulation layer is fixedly held in an enclosed space defined in between the binding frame, the outer shell and the inner shell. With the binding frame, different components of the cooler box can be more easily assembled together to reduce the assembling time and increase the productivity.
