This application claims priority to co-pending provision application “Paper Bag Mouth Opening Support” filed on Oct. 31, 2008, Ser. No. 61/110,211, the contents of which is hereby incorporated by reference.
FIELD OF THE INVENTIONThis disclosure is related generally to foldable bags and similar structures and more particularly to stiffening devices for stiffening fold lines in foldable paper bags.
BACKGROUND OF THE INVENTIONMany people use paper bags to collect, store and dispose of refuse. An example includes the common brown paper bags used in grocery stores to transport groceries. A second example is the taller version of brown “leaf bags” sold in hardware stores. The primary use of the leaf bags is to store refuse, and grocery bags are often secondarily used for refuse.
While these bags are very useful for storing and disposing refuse, they can be difficult to use given their tendency to either flop over when empty or have their mouth opening flop shut when not held open by a user. Accordingly, when attempting to place refuse (or any other item) in the bag, it is quite common for spills to occur because the bag is not in the maximal, upright and open position.
Various devices and approaches have been proposed to overcome such deficiencies, including “frames”, “stands” and relatively large devices that are inserted into the bag, or which hold the bag. Unfortunately, these typically require additional structures separate from the bag itself that are heavy and/or relatively expensive. Accordingly, a more efficient approach is desired.
SUMMARY OF THE INVENTIONThe present invention provides a stiffening system and method for stiffening a fold line that separates adjacent sections of a paper bag or other similar structures.
In one embodiment, there is a foldable bag, comprising: a fold line; a first adjacent section and a second adjacent section separated by the fold line; and a stiffener having a first portion pre-fastened to the first adjacent section and a second portion that includes a mechanism for manual attachment to the second adjacent section to maintain the foldable paper bag in an open position.
In a second embodiment, there is a method of implementing a foldable bag, comprising: forming the foldable bag to include a fold line that separates a first adjacent section and a second adjacent section; and pre-fastening a first portion of a stiffener to the first adjacent section, wherein the stiffener includes a second portion having a mechanism for manual attachment to the second adjacent section to maintain the foldable bag in an open position.
In a third embodiment, there is a bag stiffening system, comprising: a foldable bag having a fold line separating a first adjacent section and a second adjacent section; and a stiffener, wherein the stiffener comprises a substantially flat piece of material having an adhesive on one side, said stiffener being adapted to be manually adhered to the first adjacent section and the second adjacent section across the fold line.
The illustrative aspects of the present invention are designed to solve the problems herein described and other problems not discussed.
These and other features of this invention will be more readily understood from the following detailed description of the various aspects of the invention taken in conjunction with the accompanying drawings.
The drawings are merely schematic representations, not intended to portray specific parameters of the invention, and are not necessarily drawn to scale. The drawings are intended to depict only typical embodiments of the invention, and therefore should not be considered as limiting the scope of the invention. In the drawings, like numbering represents like elements.
DETAILED DESCRIPTION OF THE INVENTIONThe present invention provides a solution for supporting two or more adjacent foldable sections of a paper bag or other similar structures.
Bag 10 includes side sections 12, 14, 16, 18, 20 and 22. As can be seen, side sections 12 and 14 are separated by a vertical fold line 34, and side sections 18 and 20 are separated by a vertical fold line 36. Attached to side sections 14 and 20 are a pair of stiffeners 24 and 26, which are shown in an un-deployed position. In this embodiment, each stiffener encompasses a relatively flat, straight, stiff piece of material having a portion that is pre-fastened to one of two adjacent side sections separated by a fold. For instance, a portion of stiffener 24 is pre-fastened to side section 24 with an adhesive 28. In this un-deployed mode, a second portion of the stiffener 24 extends un-fastened to any side section, thus allowing the bag 10 to be folded, e.g., for storage.
Although described herein being attached with an adhesive, stiffener 24 may be pre-fasted to side 14 in any manner, e.g., using staples, tape, tabs/cut-outs, rivets, etc. Stiffener 24 may be made from any material that provides a requisite amount of stiffness for holding two (or more) adjacent sections in place. In one embodiment, stiffener 24 may be made from a biodegradable material, such as cardboard or fiber board. A typical stiffener for the embodiment of
On the non-pre-fastened portion of stiffener 24 is a second adhesive 30 that may be provided with a removable covering 32. Removable covering 32 may comprise a biodegradable material such as paper that can be easily removed and deposited into the bag 10 as waste. Once removed, exposed adhesive 30 can be manually secured to side section 12 to deploy the stiffener 14. In an alternative embodiment, rather than using an adhesive 30, stiffener 24 could be attached to side section 12 using other known techniques, e.g., tape, string, tabs/cut-outs, riveting, the adhesive commonly found on 3M® “sticky notes”, etc.
It is understood that although shown with two stiffeners 24, 26, bag 10 may include any number or arrangement of stiffeners. Moreover, although described as flat and straight, stiffeners 24, 26 could be implemented in other configurations, e.g., angled, curved, etc. Furthermore, although described as having one portion that is pre-fastened to a section of the bag, stiffener 24 could be provided as an add-on device, with an adhesive that could be attached to two (or more) adjacent sections. Accordingly, stiffeners may be integrated into a bag during manufacture, or provided as an add-on device for later attachment. Still further, although shown being attached to interior side sections of bag 10, stiffeners could be implemented to attach to exterior side sections. Finally, it is also understood that the particular shape, dimensions, and material used to implement a stiffener can vary depending upon the particular amount of stiffness required.
As noted, stiffeners may be utilized to stiffen any fold line that joins adjacent sections in a foldable bag or similar structure.
Also shown in
As noted, pre-fastening of one or more stiffeners onto sections of a bag or similar structure may be done in-line during the manufacturing of the bag. Any technique for attaching stiffeners may be utilized during such a process, and such techniques are well understood in the art of packaging and constructing paper bags and similar structures. Typical paper bags are manufactured with rolls of continuously fed paper, rotary and pinch rollers, cutting blades, folding devices and press rollers. Stiffeners may be adhered to the bag during any step of the process, and more particularly may be adhered in manner similar to the process in which paper handles are fasted to paper bags.
Alternatively, stiffeners may be provided as an add-on device (e.g., packaged separately with the bag) that includes any mechanism for attachment to adjacent sections that are separated by a fold line. In still a further embodiment, a first component of the stiffener could be integrated with the bag (e.g., adhesive strips) and a second component could be added when needed (e.g., a stiffening strip).
Note that the terms “vertical” and “horizontal” fold lines are not intended to be limiting to a particular orientation, but are instead intended to describe fold lines found on a typical grocery or leaf bag.
Although specific embodiments have been illustrated and described herein, those of ordinary skill in the art appreciate that any arrangement which is calculated to achieve the same purpose may be substituted for the specific embodiments shown and that the invention has other applications in other environments. This application is intended to cover any adaptations or variations of the present invention. The following claims are in no way intended to limit the scope of the invention to the specific embodiments described herein.
