PACKAGING HAVING PROTECTIVE MATERIALS INCORPORATED THEREIN
A packaging article for protectively storing perishable paper products that includes protective materials that protect the packaging article and its contents from any of a number of threats including water damage, fire damage, mold, insects, bacteria, fungi and theft. The packaging article comprises a bottom wall, side walls and a closure that surround and define an interior cavity in which the paper products are stored or transported. Each of the bottom wall, side walls and closure are made from a plurality of layers. Protective materials are applied to one or more of the bottom wall, side walls and closures by either impregnating a paper or cardboard with a suitable chemical, applying a film thereover, spraying a coating thereover or sandwiching the protective material between two adjacent layers. Suitable chemicals that produce the desired properties include, but are not limited to wax, oil, plastic, polybrominated diphenyl ether, polybrominated biphenyl, brominated cyclohydrocarbons, boric acid and hydrogen peroxide. A radio frequency identification tag may also be received within the wall of the packaging article to protect the same against theft.
This application is a continuation-in-part of U.S. patent application Ser. No. 11/703,966, filed Feb. 8, 2007, the entire specification of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION TECHNICAL FIELDThis invention generally relates to storage and transportation materials. More particularly, the invention relates to mailing and storage boxes and envelopes. Specifically, the invention relates to boxes and envelopes that are made of a plurality of different layers that have protective materials incorporated therein or applied thereto to protect the article from a variety of different threats.
BACKGROUND INFORMATIONOffices and individuals frequently need to store materials such as files and papers for long periods of time. Typically, these materials are placed in some sort of storage box for safekeeping. These boxes may take a variety of forms including plastic tubs or corrugated cardboard boxes with lids. Plastic tubs are convenient and protect the materials stored therein from dangers such as liquid exposure, but can be relatively expensive if large volumes of materials need to be stored. Cardboard boxes on the other hand are inexpensive and convenient, but they are vulnerable to dangers such as water damage, fire, insects and mold.
There is therefore a need in the art for an improved corrugated cardboard box that is less vulnerable to threats that may damage the contents of the box.
SUMMARY OF THE INVENTIONThe device of the present invention comprises a packaging article for protectively storing perishable paper products that includes protective materials that protect the packaging article and its contents from any of a number of threats including water damage, fire damage, mold, insects, bacteria, fungi and theft. The packaging article comprises a bottom wall, side walls and a closure that surround and define an interior cavity in which the paper products are stored or transported. Each of the bottom wall, side walls and closure are made from a plurality of layers. Protective materials are applied to one or more of the bottom wall, side walls and closures by impregnating a paper or cardboard layer with a suitable chemical, applying a film thereover, spraying a coating thereover or sandwiching the protective material between two adjacent layers. Suitable chemicals that produce the desired properties include, but are not limited to wax, oil, plastic, polybrominated diphenyl ether, polybrominated biphenyl, brominated cyclohydrocarbons, boric acid and hydrogen peroxide. A radio frequency identification tag may also be received within the wall of the packaging article to protect the same against theft.
The preferred embodiments of the invention, illustrative of the best mode in which applicant has contemplated applying the principles, are set forth in the following description and are shown in the drawings and are particularly and distinctly pointed out and set forth in the appended claims.
In accordance with a specific feature of the present invention, each of the bottom wall, side walls 52 and lid 58 of box 50 are manufactured from a corrugated cardboard that has been specially treated with one or more of several protective materials as will are hereinafter described.

In accordance with one of the specific features of the present invention, one or more layers of the bottom wall, side walls 52 and lid 58 of box 50 include protective materials that impart improved protective properties to the storage box 50. In a first instance, shown in
With reference to
The protective layer 66 may constitute cardboard that is impregnated with a chemical that renders that layer water impervious or water repellant. The chemical may render the layer fire resistant or fire retardant. The chemical may be a fungicide that prevents mold from growing, or a pesticide that kills insects such as silverfish or that repels such insects because of an odor or taste associated therewith. A wide variety of chemicals are known to produce these properties, but have not been previously applied to corrugated cardboard or have not been applied in combination with each other to cardboard. So, for instance, a wide variety of chemicals and chemical components may be used for these purposes. These include, but are not limited to, a wax, or an oil may be impregnated into the layer, or a plastic film may be used to create a water repellant or resistant layer. Chemicals such as aluminum hydroxide and diammonium phosphate, polybrominated diphenyl ether, polybrominated biphenyl or brominated cyclohydrocarbons can be sprayed or otherwise applied to a one of the layers 60, 62 or a separate cardboard sheet in order to create a fire retardant layer. Boric acid or hydrogen peroxide may be used in layer 66 to act as a pesticide or fungicide. So, for example, in
It will be understood by those skilled in the art that one or more or all of these and other chemical compounds may be applied to the cardboard in one or more layers in order to protect the box from one or more of water, fire, insects and mold. Furthermore, any other chemical or substance may be applied to the interior or exterior of box 50, or may be impregnated into the cardboard layers thereof in order to give the materials thereof the protective qualities that are desired.
In accordance with one of the specific features of the present invention, walls 710 and 712 are manufactured from a plurality of layers. One or more of those layers include materials that impart protective properties to envelope 700. Walls 710 and 719 may be integrally formed or may be secured together in some suitable manner. Walls 710 and 712 surround and define an interior cavity 714 into which the articles to be mailed are placed.
Finally,
As with the storage box, the protective layers in envelope 700 may be impregnated into the material of the layer, applied as a film, applied as a spray coating or may be sandwiched between the various layers within envelope 700.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
Moreover, the description and illustration of the invention are an example and the invention is not limited to the exact details shown or described.
