1. Field of the Disclosed Subject Matter
The disclosed subject matter relates to collapsible bags. Particularly, the present disclosed subject matter is directed to a collapsible bag that is retainable in its collapsed position, while permitting access to the contents of the bag.
2. Description of Related Art
A variety of structures and methods are known for collapsible bags in which items or articles can be carried or transported. This collapsible feature is especially useful when an individual is travelling and may need more or different types of bags at the individual's travel destination or may need additional bags either during the trip to or the trip back from the destination, but not for the entire round trip.
The actual transport or storage of a collapsible bag by the individual, however, is often somewhat of an inconvenience. For example, collapsible bags are not typically designed to be maintained in their collapsed state. Thus, there is a tendency for the bags to unfold, especially when the luggage in which they are stored are subjected to the harsh treatment often endured by luggage during travel. Accordingly, some prior art designs include a closure means to maintain the bag in a collapsed configuration, an example of which is disclosed in U.S. Pat. No. 6,640,856, the entirety of which is hereby incorporated by reference.
However, with conventional collapsible bags, when the bags are folded into the collapsed configuration, the bags are configured for storage only, i.e., the contents of the bags are removed prior to folding. Furthermore, the interior of the bag is not accessible when in the collapsed configuration.
There thus remains a need for an efficient and economic method and system for a collapsible bag with a variety of closure mechanisms that maintain the bag in the collapsed configuration while permitting access to the contents and interior of the bag.
The purpose and advantages of the disclosed subject matter will be set forth in and apparent from the description that follows, as well as will be learned by practice of the disclosed subject matter. Additional advantages of the disclosed subject matter will be realized and attained by the methods and systems particularly pointed out in the written description and claims hereof, as well as from the appended drawings.
To achieve these and other advantages and in accordance with the purpose of the disclosed subject matter, as embodied and broadly described, the disclosed subject matter includes a bag, and corresponding method of converting or collapsing a bag from a first expanded position to a second collapsed configuration. The foldable bag comprises a compartment for holding articles including first and second opposing body panels constructed of a foldable material and connected to each other along a pair of sides and a bottom bridging the pair of sides to define an open mouth formed opposite the bottom. In one embodiment, at least one strap is coupled to the first panel, the at least one strap disposed proximate the mouth and including a first fastening member. Additionally, a second fastening member is disposed on the first panel proximate the bottom, with the first and second fastening members configured to be releasably attached. The sides and the bottom of the compartment are foldable to collapse the compartment with the at least one strap extending outward beyond a boundary of the compartment when in a collapsed configuration, wherein the compartment is maintained substantially in the collapsed configuration when the first fastener is attached to the second fastener.
In this embodiment, a first strap extends outward beyond a first boundary of the compartment when in a collapsed configuration, and a second strap extends outward beyond a second boundary of the compartment when in a collapsed configuration. Further, the first and second fastening members are snap fasteners, and the bag includes a carrying handle attached to the compartment proximate to the mouth for carrying the bag. In accordance with an aspect of the disclosed subject matter, the mouth remains substantially open when the compartment is in the collapsed configuration, and the first and second panels include a closure device, e.g., a zipper arrangement, disposed proximate the mouth for closing the opening of the compartment.
A first side of the first panel is stitched to a first side of the second panel, and a second side of the first panel is stitched to a second side of the second panel. Alternatively, the compartment comprises a single piece of fabric for the first and second panels with a fold defining the bottom. Additionally, the first panel can include an external pouch disposed proximate the mouth, the at least one strap disposed laterally adjacent the pouch.
In another embodiment, the foldable bag comprises a compartment for holding articles including first and second opposing body panels constructed of a foldable material and connected to each other along a pair of sides and a bottom bridging the pair of sides to define an open mouth formed opposite the bottom. A reclosable flap member is coupled to a panel, and includes a strap having a first end and a second end, with the first and second ends coupled to the reclosable flap member to define a retention loop. The sides and the bottom of the compartment are foldable to collapse the compartment with the compartment maintained substantially in the collapsed configuration when the sides are disposed within the retention loop.
In use, the mouth remains substantially open when the compartment is in the collapsed configuration. Additionally, the first and second panels include a closure device, e.g., a zipper arrangement, disposed proximate the mouth for closing the opening of the compartment. The reclosable flap member is disposed on the first panel proximate the mouth and includes at least one fastening member to engage a fastening member disposed on the first panel.
In another embodiment, the foldable bag comprises a compartment for holding articles. The foldable bag includes first and second opposing body panels constructed of a foldable material and connected to each other along a pair of sides and a bottom bridging the pair of sides to define an open mouth formed opposite the bottom. Additionally, a strap is provided having a first end and a second end, with the first and second ends coupled to the compartment proximate the bottom to define a retention loop. At least one carrying handle is coupled to the compartment proximate to the mouth for carrying the bag wherein the sides and the bottom of the compartment are foldable to collapse the compartment with the compartment maintained substantially in the collapsed configuration when the at least one carrying handle is advanced through the retention loop.
In use, the mouth remains substantially open when the compartment is in the collapsed configuration. Additionally, the first and second panels include a closure device, e.g., a zipper arrangement, disposed proximate the mouth for closing the opening of the compartment. Additionally, the strap is disposed on the bottom of the compartment.
