Abstract
A method for containerlessly packaging non-woven safety garments to minimize particulate shedding, including at least partially filling a pressing cavity of a orthorhombic parallelepiped shape with compressible, non-woven safety garments, applying isostatic pressure to the cavity to compact the garments into a compressed mass, wrapping the compressed mass and removing the compressed mass from the cavity. The wrapped compressed mass retains a substantially rectangularly parallelepiped shape and is substantially free of loose particulate matter.
Description
- The present application is a divisional application claiming priority to pending U.S. patent application Ser. No. 11/428,728, filed on Jul. 5, 2006, which is a continuation-in-part of U.S. patent application Ser. No. 10/798,646, filed Mar. 11, 2004, now abandoned.
- The present technology relates generally to the field of packaging, and more specifically to a method and apparatus for providing boxless and regularly shaped stackable packages of safety garments.
- Safety garments, such as disposable smocks, jumpsuits, gloves, shoe coverings, and hair coverings, are required apparel for the performance of many jobs. Some of the jobs requiring safety garments are performed in clean room environments, wherein it is desired that the introduction of foreign matter be minimalized. For example, technicians in certain sensitive medical fields dealing with infectious matter, aerospace researchers assembling interplanetary probes, and material scientists developing and manufacturing ultrapure materials all wear safety garments in clean room environments. The safety garments perform the dual function of protecting the wearer from the potentially hazardous materials he is working with as well as preventing unwanted matter from the wearer's person from contaminating his work product.
- Safety garments are typically provided in lots containing a plurality of identical safety garments. These lots are typically provided in boxes made of a structural material such as cardboard, and are shaped as regularly sized rectangular blocks for ease of storage and handling. The safety garments are typically packed into these boxes, either by hand or by machine. One drawback of providing boxed safety garments is that particulate organic material may from the packaging process and/or from the box itself may adhere to the safety garment, thus partially defeating the purpose of the clean room environment. Further, the boxes themselves tend to attract vermin such as rodents and insects that enjoy consuming organic comestibles such as cardboard packaging. In addition to producing excess packaging particles when consuming the packaging material, such vermin also contribute even more particulate contamination in the form of carried dirt, shed hair, fecal waste matter, and the like. Thus, cardboard boxes are problematic for the transport and storage of safety garments intended for clean room use.
- One partial solution has been to bag the safety garments in polymer bags or the like that do not contribute particulate contaminants and do not attract vermin. The problem with this approach is that the bags are inherently irregularly shaped and are thus not easily or conveniently stacked for storage and transport. Another partial solution has been to package the safety garments in boxes made of inorganic materials, such as plastics or metal that do not shed particulate contaminants and do not attract vermin. However, such packaging materials are inherently more expensive than traditional boxes and cannot be easily broken down for disposal, contributing even more expense to the enclosed products.
- There thus remains a need for a need for an inexpensive packaging system that does not contribute particulate contamination, does not attract vermin and may be easily stacked for storage and readily disposed of after it has served its purpose. The presently claimed technology addresses this need.
- The claimed technology relates to a method and apparatus for compressively packaging safety garments to form stackable wrapped blocks. Compressible safety garments are placed into a rectangular parallelepiped compression chamber and an isostatic ram operationally connected to the compression chamber is inserted thereinto to apply a compression force to the garments. The resulting compressed rectangular parallelepiped blocks are wrapped in flexible plastic wrapping material to yield wrapped rectangular parallelepiped blocks that may be stacked and stored for future use.
- One object of the claimed technology is to provide an improved method and apparatus for packaging safety garments. Related objects and advantages of the claimed technology will be apparent from the following description.

FIGS. 1-7 schematically illustrate a first embodiment of the claimed technology, apackaging apparatus 10 and method for the containerless or boxless packaging ofnon-woven garments 12, such as smocks or coveralls made from spunbond/melt blown/melt blown/spunbond (SMMS) material and the like. Thenonwoven garments 12 are characterized by a substantial lack of fibers as well as by an associated loose density. The nonwoven garments are likewise typically characterized by a substantial lack of associated loose particulate matter; in other words, the nonwoven/nonfibrous nature of thegarments 12 does not lend itself to the generation of loose particulate matter. - The
packaging apparatus 10 includes a cavity orchamber 14 for compressing a plurality ofsafety garments 12 placed thereinto. Thechamber 14 typically includes arectangular base 16 with four generallyplanar walls 18 extending perpendicularly therefrom to define an orthorhombicparallelepiped enclosure 14. In some embodiments, thebase 16 is a square. Thechamber 14 more typically defines a volume from about 4500 cubic inches to about 8100 cubic inches. In some embodiments, thechamber 14 is a cube. - The
chamber 14 is sized to receive anisostatic ram member 20, shown in detail inFIG. 2 . Theisostatic ram member 20 is operationally connected to thechamber 14 and is able to move into thechamber 14 to provide a compressive force to the interior of thechamber 14 sufficient to compressnonwoven safety garments 12 loaded into thechamber 14 and remove substantially all of the entrapped air therefrom. Typically, aram 20 pressure of about 80 PSI is sufficient to compress thegarments 12 and facilitate removal of most or all of the entrapped air from thechamber 14. Also typically, there is sufficient gap between theram member 20 and thechamber walls 18 to allow air to escape as theram member 20 is introduced into thechamber 14. - The
apparatus 10 typically further includes avacuum system 26 for pulling a partial vacuum on thechamber 14 during the compression operation. Thevacuum system 26 includes avacuum pump 28 fluidically connected to thechamber 14 such that actuation of thevacuum pump 28 reduces the air pressure in thechamber 14. Thevacuum system 26 further includes anair conduit 30 pneumatically or fluidically connected to thechamber 14 for at least partially removing the air therefrom, and also an enclosure defining avacuum chamber 32 within which thechamber 14 is disposed. Thevacuum chamber 32 is shown herein schematically, and may be of any convenient configuration sufficient to allow the generation of a partial vacuum within thecompression chamber 14. - The
apparatus 10 further includes means for wrapping acompressed block 36 with a flexible nonshedding wrappingmaterial 38 to yield an substantially orthorhombic parallelepiped-shaped block ofcompressed safety garments 40, such as a polymer sheet, plastic film, or the like. Such means is illustrated schematically herein, and may comprise any convenient automated wrapping technology in the art. The polymer wrappingmaterial 38 is typically a polymer material capable of sustaining a pressure differential (i.e., vacuum wrapping a bundle of compressed garments 12) and is more typically polyethylene, polypropylene, polyester (such as MYLAR®) or the like. The polymer wrappingmaterial 38 is typically of sufficient thickness to retard gas leakage thereacross. In the case of a polyethylene wrappingmaterial 38, the typical sheet thickness is about 4 mils. However, any convenientflexible wrapping material 38 of sufficient thickness to wrap acompressed block 36 sufficiently to retain its substantially orthorhombic parallelepiped shape may be selected. Moreover, by wrapping theblock 36 in additional layers, thinner and moredeformable wrapping material 38 may be suitable. - In operation, a number of
compressible safety garments 12 are typically folded and stacked, and then placed into thechamber 14. Typically, between about 10 and about 15 pounds ofsafety garments 12 are placed into thechamber 14 at once. The chamber is typically sized to accept the stack ofsafety garments 12 with a minimum amount of excess volume. Prior to loading withgarments 12, the interior of thechamber 14 is typically lined with a polymer orplastic wrapping material 38, such that thesafety garments 12 are placed into the wrappingmaterial 38 as they are placed in thechamber 14. Alternately, the wrappingmaterial 38 may be applied to the compressedmass 36 after the removal of the compressedmass 36 from thechamber 14. - Typically, a partial vacuum is then produced within the
chamber 14 and thesafety garments 12 are then isostatically pressed to compact their volume and remove entrapped air. However, the compaction process does not necessarily require the presence of a partial vacuum and may be performed at standard air pressure. Typically, the safety garments are compacted to a density of between about 2 and about 5 times their associated loose density, and more typically to about 3 times their loose density. Typically, a force of between about 50 and about 120 PSI is sufficient to achieve such compression. Typically, the density of acompressed mass 36 is about 0.004 pounds per cubic inch. - The wrapping
material 38 is then sealed (the sealing process is typically but not necessarily performed under a partial vacuum) and the resultingcompressed block 36 is removed from thechamber 14. Typically, theblock 36 is again wrapped with wrapping material 38 (i.e., the compressed block ofgarments 36 is double wrapped) and the outer wrapping 38 is then sealed (typically heat sealed); alternately, theblock 36 may be heat sealed or otherwise sealed after its initial compression. More typically, a polymer orplastic gusset 39 is wrapped around theblock 36 to assist in the retention of the block shape; still more typically, two ormore gussets 39 are wrapped around the block; thegussets 39 may be layered, oriented around different sides of the block (i.e., one horizontally and another vertically) or the like. Theresultant package 40 has the shape of an orthorhombic (typically rectangular) parallelepiped and retains that shape during shipping, stacking (typically three ormore packages 40 deep) and storage. In one embodiment, thepackage 40 has dimensions of about 16×14×12 inches and has a mass of about 11 pounds. - Typically, the
package 40 is substantially free of loose particulate matter, both externally and within. More typically, removal of the wrappingmaterial 38 does not substantially generate particulate material. In other words, neither the wrappedprotective clothing 12 nor the wrappingmaterial 38 making up thepackage 40 are substantial sources of particulate shedding, during packaging, transport, storage, unwrapping and/or use. - While the claimed technology has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character. It is understood that the embodiments have been shown and described in the foregoing specification in satisfaction of the best mode and enablement requirements. It is understood that one of ordinary skill in the art could readily make a nigh-infinite number of insubstantial changes and modifications to the above-described embodiments and that it would be impractical to attempt to describe all such embodiment variations in the present specification. Accordingly, it is understood that all changes and modifications that come within the spirit of the claimed technology are desired to be protected.
