Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates in general to a process for packaging furniture, and more particularly, to a process for packaging a polyurethane foam filled article of furniture.

2. Background Art

Processes for packaging furniture have been known in the art for several years. Furthermore, processes for packaging polyurethane foam filled articles of furniture have likewise been known in the art. Such polyurethane foam filled articles of furniture may comprise structures which, among others, are analogous to the chairs disclosed in: U.S. Pat. No. 6,279,184 B1; U.S. patent application Ser. No. 09/941,064, Entitled “Frameless Chair;” U.S. patent application Ser. No. ______, Entitled “Frameless Chair;” and U.S. Provisional Patent Application Serial No. 60/276,593, all of which are hereby incorporated herein by reference in their entirety. Alternatively, articles of furniture may comprise structures which include a component or components which are polyurethane foam filled, as well as a component or components which are not polyurethane foam filled, such as, for example, a futon comprising a polyurethane foam filled article and a frame. While such conventional packaging processes for polyurethane foam filled articles of furniture or components of furniture have become popular, the size of the packaged articles of furniture, among other things, remains largely problematic. In particular, using boxes, bags, or conventional packages to retain polyurethane foam filled articles of furniture requires that the box, bag, or conventional package be of substantial size. Consequently, conventional means of shipping, such as, for example, the United Parcel Service (UPS), Federal Express, or the United States Postal Service, may be expensive and/or unfeasible inasmuch as restrictions on the size of packages may drastically increase the price or even prohibit such large items from being shipped.

It is therefore an object of the present invention to provide a process for packaging a polyurethane foam filled article of furniture which, among other things, remedies the aforementioned detriments and/or complications associated with packaging polyurethane foam filled articles of furniture.

Moreover, it will be understood that polyurethane foam filled article of furniture 12 may be one component of an article of furniture which may comprise frameless and non-frameless components.
Bag associating [0037] step 40 generally comprises the step of associating polyurethane foam filled article of furniture 12 with a bag 16 having an aperture 18. More particularly, bag associating step 40 includes the step of placing polyurethane foam filled article of furniture 12 inside bag 16, through aperture 18. Bag 16 may comprise any one of a number of sizes, shapes, and/or materials—with the only limitation being that it must be capable of retaining polyurethane foam filled article of furniture 12. Examples of suitable materials for fabricating bag 16 include conventional substantially airtight, flexible materials such as, for example, a bag fabricated from plastic, natural and/or synthetic materials, etcetera. Aperture 18 may comprise any one of a number of sizes and shapes—its only limitation being that it must be capable of allowing polyurethane foam filled article of furniture 12 to pass therethrough.
Reducing step [0038] 50 generally comprises the step of reducing initial volume 14A of polyurethane foam filled article of furniture 12 to a reduced volume 14B. As is shown in FIG. 1, initial volume 14A of polyurethane foam filled article of furniture 12 is shown in step 50A, prior to reducing step 50, and reduced volume 14B of polyurethane foam filled article of furniture 12 is shown in step 50B, subsequent to reducing step 50.
Reducing step [0039] 50 may include providing a vacuum source 52 which is capable of decreasing air pressure within a confined area, such as, for example, bag 16.
