A luggage container includes: a main compartment having a front side and a backside; a cover portion coupled to the main compartment to cover the front side of the main compartment and configured to be open or closed via a first opening/closing mechanism element to expose or cover the main compartment; an expandable portion extendingly coupled to the main compartment, the expandable portion comprising a second opening/closing mechanism element; a storage compartment including an opening portion formed at the expandable portion and a pocket portion extending from the opening portion such that the pocket portion of the storage compartment is located in the main compartment; and a strap having a first locking structure and a second locking structure that are configured to be locked or unlocked, the strap coupled to an inner portion of the storage compartment.

A luggage includes a first case, a second case, and a connecting portion. The connecting portion has a pair of teeth rows connected to the first case and the second case respectively and two sliders engage the teeth rows. The sliders are moved to make the teeth rows mesh together or separate. When the sliders are moved to separate the teeth rows and they are moved to the same side of the second case, the meshed section of the teeth rows becomes a hinge of the second case for opening and closing the luggage. As a result, the second case is capable of being opened in all directions.

A wheeled luggage case comprises (a) a storage chamber, (b) a cover defining an opening on at least one side of the storage chamber for providing ready access therein and at least two labyrinth axle-free wheels operatively connected to the chamber for towing the case along a ground surface. The labyrinth axle-free wheel comprises an internal rim, an external rim provided with a ground interface, rollers being rotatably disposed within a roller spacer between the internal and external rims in a uniform circumferential manner by means of a spacer and external covers. A labyrinth type dust passage in the wheel is defined by the rims and the external plates mechanically connected to the internal rim.

An extendable luggage comprises a first shell having a first opening edge, a second shell having a second opening edge, an inner zipper, an outer zipper and an inner strap. The inner zipper has outer teeth located at a first and second distance away from the first and second opening edge, respectively. The outer zipper has two outer tapes and outer teeth. Each outer tape has a straight section, a head section and a tail section. The outer teeth located at distal ends of the two head sections and two tail sections are closed and unable to be opened. The outer teeth located at the two straight sections are located at a third distance away from the first opening edge and a fourth distance away from the second opening edge. The inner strap is connected with two ends of the inner zipper. The luggage looks simple and is extendable.

An expandable luggage container includes a first compartment; a side cover formed on a side of the first compartment, a first zipping mechanism formed around three sides of the side cover; a second compartment coupled to the first compartment; and a top cover formed on a top side of the second compartment, a second zipping mechanism formed around three sides of the top cover. In the luggage container, a first opening of the first compartment and a second opening of the second compartment are directed to different directions; the second compartment is collapsible by a third zipping mechanism formed between the first compartment and second compartment; and the luggage container is in a compact mode when the second compartment is collapsed and is in an expanded mode when the second compartment is expanded by unzipping of the third zipping mechanism.

A luggage container includes: a main compartment; a cover portion coupled to the main compartment and configured to be open or closed via a first opening/closing mechanism element to expose or cover the main compartment; an expandable portion extendingly coupled to the main compartment, the expandable portion comprising a second opening/closing mechanism element; and a storage compartment comprising an opening portion formed at the expandable portion and a pocket portion extending from the opening portion such that the pocket portion of the storage compartment is located in the main compartment.

There is provided a returnable box, which is capable of conveying clothes under a state of being hung from a hanger, and prevents falling of the hanger during conveyance without requiring a complicated operation. A returnable box according to the present invention includes: a box main body configured to store clothes thereinside; and a hanger hooking member attached inside the box main body. The hanger hooking member includes a fixing member and a hanger hooking main body including a hanger bar on which a hook of a hanger is hooked, and the fixing member is attached to the hanger hooking main body under a state of being extended along a longitudinal direction of the hanger bar above the hanger bar.

A double open end zipper for both end positioning-based luggage includes first and second housing members respectively equipped with an N-shaped plastic strip at the rim thereof, and a double open end zipper including first and second zipper tapes respectively stitched to the N-shaped plastic strips at the first and second housing members in reversed directions with the box and pin of the first zipper tape respectively disposed adjacent to the pin and box of the second zipper tape subject to the guidance of a mark line at each N-shaped plastic strip, a seam allowance constraint block located at an outer rear side of the box of each of the first and second zipper tapes, two zipper sliders respectively coupled to first and second zipper tapes, allowing adjustment of the combined storage capacity defined in between the first and second housing members.

Collapsible portable containers having a foldable wall section with shape-retaining characteristics are disclosed. In particular, collapsible, wheeled suitcases and trolleys are provided. One or more casters of a collapsible suitcase may be retractable to permit a folding region of a wall section to overlap the depth dimension of the casters when in the collapsed position. The folding region may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier. The non-folding tier may be of the same material as the flexible tiers but stiffer due to its geometry, or it may be composed of a different, relatively rigid material.
