Definitions

  • the present invention is directed to flexible packaging and method which is more efficient and effective than current designs in containing and protecting foods and other articles, and in particular has specific advantages when used in conjunction with evacuated containment.
  • Earliest flexible packaging utilized single ply flexible films or sheet stock to contain goods. Closure was accomplished by wrapping goods, such as with clear plastic films, or by twist ties, overlapping closures, clips, molded in zippers, or by other means. Later improvements to closures included heat welding pouches of single ply material around stored articles.
  • An improvement over single ply materials used two or more ply laminate sheets which allowed for a heat sealable layer backed by a gas impermeable layer, thus preventing oxygen or other harmful gasses from seeping in and contaminating package contents.
  • vacuums were used to reduce package gas content, and where appropriate, to help retard microbe growth.
  • a first embodiment of the present invention as shown in Figure 1, comprises sheets 22 and 24, welded together along side seams 26 and 28, and bottom seam 30 to form pouch 31.
  • Figures 2, 3 and 4 show three example constructions for dotted area 20 defined in Figure 1. All three show raised irregular surface 29 ( Figure 1) with differences between constructions comprising primarily the distribution and form of irregularities.
  • Raised irregular surfaces such as 30, 32 and 34, shown in Figures 2, 3 and 4 respectively, form air passages 36 within pouch 31 when the interior of sheet 24 is formed flat, as shown in Figure 9, or is formed with a raised irregular surface 41, as shown in Figure 10.
  • Raised irregular surfaces 30, 32 or 34 may also form air passages 38 when contacting smooth surfaces 40 of pouch 31 contents, as shown in Figure 11.
  • Air passages 36 and 38 allow circulation of gasses within pouch 31. As examples, this circulation may be used to more fully evacuate pouch 31 when pulling a vacuum from end 42 of pouch 31, or to help preserve pouch 31 contents, such as the use of CO 2 sealed inside a closed container to help preserve apples. Air passages 36 and 38 may also help to provide for a more uniform environment to help more evenly preserve and protect pouch 31 contents.
  • Raised irregular surfaces 30, 32 and 34 shown in Figures 2, 3 and 4 respectively, as well as air passages 36 and 38 may also help provide physical protection for pouch 31 contents if pouch 31 and its contents are struck against other objects, or pouch 31 and its contents are rested for periods of time against adjacent surfaces.
  • Raised irregular surface 29 may be continuously irregular, as a few examples; like the surface of sandpaper (see example - Figure 6) or the bubbles on the surface of beer foam (see example - Figure 5); or raised irregular surface 29 may have spaced apart irregular protuberances from an otherwise regular surface (see example - Figures 3 and 8).
  • Raised irregular surfaces may have orientation such as the surface of a steel wool pad which has parallel linear orientation of irregularly undulating elongated fibers. Such orientation may also be in the form of a star burst, or a splay, or a weave, etc.
  • Raised irregular surface 29 may be: irregular in plan view but uniform in profile; or irregular in profile but regular in plan view; or irregular in both plan and profile. Such use of the terms “irregular” or “raised irregular surfaces” herein shall encompass all of the above descriptions.
  • Sheet 24 may be fabricated in many different ways. As an example, it may be embossed through a set of rollers or in a press. This would produce a sheet with texture on both sides and a relatively uniform material thickness across the entire sheet (see examples - Figures 5, 6 and 8). Alternatively, sheet 24 might be textured on one side only (see Figure 7) through a set of rollers or by a press or by other means. Sheet 24 might be textured on both sides through rollers or a press or other means. Any of the above might be done during a lamination process. Many other fabrication techniques also might be employed in conjunction with the above or as an alternative.
  • irregular texturing may have minimal impact on such transparency, particularly because such irregular texturing generally is in close proximity to the inside surface of sheet 22 and the contents it may contact which are to be viewed.
  • raised irregular surface 29 might be interrupted where and if in any way it impaired desired transparency.
  • Raised irregular surface 29 of sheet 22 may also reduce after freezing sticking between pouch 31 and its contents. This is because there is generally less surface contact between pouch 31 and its contents than if the interior of pouch 31 were formed flat without texture. As an example, a flat surface resting against another flat surface may have near 100 percent contact, whereas a properly designed and engineered raised irregular surface may have less than 80 percent, and possibly less than 60 percent, surface contact area relative to the full exposed surface area, when contacting a flat surface (see Figure 9).
  • raised irregular surfaces When compared to flat or regular raised surfaces, raised irregular surfaces may also provide a wider variety of surface contact points for package contents with each contact point having its own unique individual contact area and amount of pressure. This in turn may provide gas circulation with a more diverse and natural flow.
  • Raised irregular surfaces when compared to raised regular surfaces, cannot replicate a regular pattern on the outer surfaces of the objects they may contact.
  • objects placed in pouches having raised regular interior surfaces may have the interior pattern of the raised regular surfaces imprinted on the object's exterior caused by freezing, cooking, storage, contact pressure against other objects, or other processes. Because raised irregular surfaces have no regular pattern, they can leave no imprint of an unnatural regular pattern where they contact objects.
  • Undesirable replication of raised regular surface patterns may be caused by the soft surfaces of packaged contents, or by microbes, or by freezer burn, or by uneven heating during cooking, or by chemical reaction, or by other reasons.
  • Raised irregular surfaces may also reduce freezer burn by more uniformly and naturally distributing moisture around contents being contacted by the raised irregular surfaces, when compared to raised regular surfaces or flat surfaces. Also, if freezer burn does occur to any degree and replicates the raised irregular surface on the surfaces of package contents, such replication is far less noticeable due to the more natural appearance of the irregular surface when compared to regular and predictable surface patterns.
  • Raised irregular surfaces may be used in a variety of applications including applications for both home and commercial use. They may be used in wrapping sheet, pouches, bags, carton interiors, or in other packaging vehicles. This may include such specific applications as Ziploc TM type bags, Saran TM Wrap type food wrapping, Food Saver TM type vacuum and heat sealable bags and rolls, etc.
  • a gas-impermeable heat-sealable laminate may be desirable for both sheets 22 and 24.
  • Sheet 22 might be fabricated with outer layer 44 ( Figure 9) made of Mylar TM and inner layer 54 ( Figure 9) made of polypropylene, with the texture being added using embossing rollers either during, before, or after the lamination process.
  • outer layer 44 Figure 9
  • inner layer 54 Figure 9) made of polypropylene
  • Raised irregular surfaces described herein may be constructed at any scale.
  • raised irregular surface 30 in figure 2 might have a surface texture of sandpaper and might have texture comparable in scale to a grit of sandpaper ranging from about 400 to about 30 ⁇ m (40 grit to 400 grit), depending on the application.
  • Raised irregular surfaces may also be beneficial when food pouches are either boiled or microwaved. This is because, as explained earlier, there may be less surface contact and less predictable surface contact between the pouches and their contents thus allowing more complete contact between liquid and solid contents of the pouch during the cooking process.
  • Raised irregular surfaces when used with vacuum pouches, may provide more complete evacuation of the pouch when compared with raised regular surfaces or flat surfaces. This is because the non uniformity of raised irregular surfaces may provide more complete and extensive pathways for gasses to evacuate.
  • Properly designed raised irregular surfaces by reducing surface contact between packaging and package contents as explained earlier, may also reduce the chances of small, inaccessible pockets being formed between packaging and packaging contents when compared to raised regular surfaces and flat surfaces. Such pockets might house moisture, or microbes, or other things deleterious to package contents.
  • raised irregular surfaces may be used throughout the interior of a bag or pouch or container or on one side only or on a portion of one or two sides, depending on the needs and economics of the application.
  • Such surfaces may be interrupted as shown in Figure 4 by interruptions 46 to ease the marking of containers, or to create measuring lines, or for creating a labeling surface, or for increased transparency, etc.
  • a bag might be formed using sheet material or a fabricated tube or by other means.
  • the bag would have raised irregular surfaces on at least part of its interior. Contents would be placed in the bag and subsequently air would be withdrawn from the bag relying at least in part on evacuation air channels formed between the raised irregular surfaces and surfaces they contact. Such evacuation could be done through the top entrance of the bag, or through a hole in the bag, or by other means.
  • the bag would then be sealed air tight using: heat welding, adhesives, mechanical fasteners, or other means.
  • the bag then might be: stored at room temperature, put into cold storage, boiled in water, frozen, put into additional packaging, or some combination of the above, possibly with other processes and/or materials involved. As an example, leftovers might be put into the bag, and the bag stored in the freezer. Later the bag might be removed from the freezer and put into boiling water to heat the contents, and then the bag might be cut open and the contents put onto a plate for serving.
  • An alternative example of embodiment use would use sheet material to be sealed around contents and air withdrawn through an edge or hole in part relying on air passages formed by raised irregular surfaces contacting other surfaces.
  • a surface texture resembling that of 60 grit sandpaper and having a texture depth from peak to adjacent valley of between 101,6 and 736,6 ⁇ m (between .004 and .029 inches) offers advantages over other designs for use in evacuated pouches and other packaging used in the home or for commercial purposes. These advantages include relatively rapid air evacuation and good economics in production using current commercially available packaging films and manufacturing techniques. It is also believed for similar reasons that raised irregular surfaces in general that practice the present inventions gain advantage if their depth from peak to adjacent valley is at least 25,4 ⁇ m (.001 inches) and with particular advantage when this dimension is more than 101,6 ⁇ m (.004 inches).
