Definitions

  • This invention relates to readily replaceable image graphics.
  • Image graphics are omnipresent in modem life. Images and data that warn, educate, entertain, advertise, etc. are applied on a variety of interior and exterior, vertical and horizontal surfaces. Nonlimiting examples of image graphics range from posters that advertise the arrival of a new movie to warning signs near the edges of stairways.
  • Readily replaceable image graphics are needed for those occasions when the length of time the graphic needs to remain at the intended location is limited to a short duration, often with a replacement image graphic substituting for the image graphic to be removed.
  • An example of an expected replacement image graphic is the movie poster identified above.
  • Readily replaceable image graphics require both the "staying power" when placed on the horizontal or vertical surface and the “leaving ease” when the image graphic is to be removed.
  • films that have an image on one major surface and a field of adhesive on the opposing major surface. Again, movie posters and other bills are often adhered to a surface. If the adhesive is pressure sensitive and capable of being readily removed without leaving adhesive residue, then the poster can be posted with staying power and removed with leaving ease.
  • Mechanical fasteners are also another method of erecting graphic images.
  • Methods such as staples or tacks have limited utility, as many surfaces are not amenable to such fastening techniques, or the underlying surface will become damaged by the fasteners.
  • Other methods such as frames with friction clips (on many transport buses), windowed cases, or poster boards made of natural (i.e., cork) or synthetic materials (i.e., polystyrene foam) can also be used for replacement graphics.
  • these approaches have the limitation of requiring a substantial initial investment to place the first graphic.
  • the graphic is limited in size by the mounting method. In the case of a frame, the size of the graphic must be controlled to within a few millimeters, or the frame will not hold the graphic. All of the above methods suffer from the fact that the fastener detracts from the graphic image, and in many cases the fastener detracts from the impact of the graphic.
  • the present invention solves problems in the art of providing readily replaceable image graphics by avoiding the use of pressure sensitive adhesives on the major surface opposite the image surface yet providing a mating or meshing action with a substrate, i.e., "substrate mating surface”.
  • the present invention solves problems in the art by providing an image graphic mating web comprising a major surface comprising an imageable area and an opposing major surface comprising a nonadhesive substrate mating surface.
  • the present invention also solves the problem of traditional mechanical fasteners by hiding the fastening method behind the graphic image.
  • Nonlimiting examples of substrate mating surfaces include surfaces that employ at least one element of mechanical fasteners in mating systems as are marketed under the brands Velcro (Velcro USA, Inc., Manchester, New Hampshire); Scotchmate (3M, St. Paul, Minnesota); and Dual Lock (3M) and as are also disclosed in U.S. Patent Numbers 4,761,318; 4,973,326; 5,066,289; 5,077,870; 5,196,266; 5,312,387; 5,316,849; 5,537,722; 5,554,146; European Patent Publication 0 426 359; and PCT Patent Publications WO 9603954 and WO 9621413.
  • the invention uses a mechanical fastener element where the head of the element is larger than the stem in at least one direction traverse to the stem.
  • mechanical fastener elements meeting this description are included in the disclosures and products identified in the paragraph immediately above, and particularly include stem/head mechanical fastener elements such as hooks in the shape of an "inverted J", a "T", and other configurations.
  • the invention is comprised of, but not limited to, a flexible polyolefin material that is shaped on the substrate contact surface into capped posts that resemble mushrooms (referred to herein as "mushroom-type hooks").
  • the imageable surface opposing side is smooth and is capable of being processed to accept an image graphic.
  • Nonlimiting examples of processing capable of making the major surface imageable include surface modification techniques such as Corona Treatment; liquid coatings dissolved or suspended in either organic solvents or water; or a 100% solids polymeric material that can be extruded or coextruded onto the surface.
  • the image can be formed by any conventional method.
  • Nonlimiting examples include solvent based inks, 100% solids ultraviolet curable inks, inkjet printing, thermal transfer imaging and electrostatic transfer imaging.
  • An image graphic mating web of the present invention can then be mated to a substrate that has at least a portion of its surface comprising a companion mating element, whether a companion element to a mechanical fastener or a loop structure that interacts with hooks of the substrate mating surface of the image graphic mating web.
  • the nature of mating described as "hook and loop" systems forms the bond.
  • Nonlimiting examples of such systems are disclosed in U.S. Patent Numbers 4,973,326; 5,066,289; 5,077,870; 5,196,266; 5,312,387; 5,316,849; 5,537,722; 5,554,146; European Patent Publication 0 426 359; and PCT Patent Publications WO 9603954 and WO 9621413; and copending, coassigned U.S. patent application serial no. 08/611,351 (Johnson et al.); the disclosures of which are incorporated by reference herein.
  • loop portion of the system can be a conventional material used in a conventional setting, such as carpeting, fabric wall coverings, woven and non-woven materials designed to accept the hook portion of the system.
  • the loop portion can be removably attached to a desired surface.
  • a further advantage of the loop system is that the higher internal strength of many loop systems compared to most films and paper substrates allows the use of a pressure sensitive with higher "staying power", while still affording relatively clean and easy removal.
  • the mating loop can be supplied with any number of pressure sensitive adhesives with various levels of "staying power", to match the characteristics of the underlying surface.
  • the loop can be fastened by alternative methods such as nails, staples, tacks or even wet adhesives in water and/or organic solvents that can be applied by methods such as brushing, troweling, spraying or self-contained aerosol cans.
  • An image graphic mating web of the present invention can be mated with a loop portion and later removed, in order to mount a new graphic. This process can be repeated for the life of the webs, which can vary from a few to thousands of applications.
  • a feature of this invention over the prior art is that the image graphic mating web is designed to be the printable substrate for the graphic.
  • the advantages of the invention that flow from this feature are the following:
  • Image graphic mating webs also have a number of advantages over the current art of using hook and loop materials for graphic applications.
  • the current art of using mechanical fastening is typified in U.S. Pat. Nos. 4,930,237; 5,024,015; 5,172,504; and 5,482,755.
  • Each of these patents is similar in that small pieces of hook and loop material are added to the finished graphic.
  • the size of the hook and loop fastening varies, or is not specified, but is shown in the drawings typically to be 5% or less of the area occupied by the graphic.
  • image graphic mating webs have a number of advantages:
  • Fig. 1 illustrates one embodiment of the invention that shows an image graphic mating web 10 having a substantially continuous backing 12 of thermoplastic resin. Integral with the backing is an array of mushroom-shaped projections or hooks 14, each having a molecularly oriented stem 16, a mushroom head 18, and a fillet 20 at the base of the stem.
  • a piece of the web 10 can be the hook portion of a hook-and-loop mechanical fastener, or it can be releasably fastened to a fabric which is penetratable by the mushroom-shaped hooks 14, or it can be configured such that two pieces of the web 10 can be interengaged to form a hermaphroditic mechanical fastener.
  • the web is substantially shown and described in U.S. Pat. No. 5,077,870, the disclosure of which is incorporated by reference herein.
  • the web 10 has the hooks 14 serving as its substrate mating surface 22.
  • the substantially continuous backing On the opposing major surface, the substantially continuous backing has an imageable surface 24 .
  • An image 26 on at least a portion of surface 24 is shown, while it is to be understood that an image can cover from 0.01-100% of the total area of surface 24 depending on the type of image to be displayed.
  • Mushroom-type hooks 14 are disposed in a selected arrangement (it is preferred that this arrangement be a predetermined pattern) on backing 12, and are formed to have a generally uniform height projection from the backing 12.
  • the selected arrangement for surface stem dispersal is preferably a uniform array, although any arrangement of surface stems is possible (including even a randomly designed dispersal of surface stems within a given area).
  • the mushroom-type hooks 14 are arrayed in staggered rows across the backing 12, Preferably, each hook of surface stems within a given area).
  • the mushroom-type hooks 14 are arrayed in staggered rows across the backing 12,.
  • each hook 14 projects at a right angle relative to surface 22, but alternatively angled stem orientations are also contemplated.
  • the mushroom-type hooks 14 and backing 12 are formed integrally, and the web 10 requires no additional support layer or backing material.
  • the hooks 14 of the preferred embodiment are equally spaced apart.
  • the hooks 14 collectively serve to define an operative region or contact surface for mating with the substrate.
  • the hooks 14 provide a very uniform frictional engaging surface for presentation to the substrate to be contacted.
  • the use of uniformly disposed and formed hooks 14 on mating surface 22 results in a highly controllable and predictable engagement relationship between the web and the substrate (e.g., floor, wall, ceiling in an interior or exterior environment).
  • the precisely formed nature of the mating surface introduces a significant mechanical engagement component into the frictional engagement relationship.
  • the upstanding hooks 14 penetrate interstices on the web surface of the substrate (e.g., between the crossed fibers of its weave for a woven web such as carpet or a woven wall covering or a tape affixed to either having a woven outer surface) to engage the web mechanically.
  • the web 10 can be molded from a number of commercially available materials.
  • moldable material useful for web 10 having hooks 14 thereon include SRD7-560 and SRD70587 impact copolymer resins (available from Shell Polypropylene Company, Houston, Texas); Prevail 3050 resin (available from Dow Chemical Company, Midland, Michigan); Himont KS084P resin (Montell-Himont, Atlanta, Georgia); and Hytrel 5526 or Surlyn 1702 resin (both available from E. I. du Pont de Nemours & Co., Inc., Wilmington, Delaware).
  • stem-shaped projections generally described in copending, coassigned United States Patent Application Serial No. 08/611,351 (Johnson et al.) (incorporated by reference herein) can also be used in this invention.
  • the stems can vary according to a number of parameters. Further aspects of mating surface 22 are described according to a combination of stem height, stem diameter, stem spacing and number of stems per cm 2 .

  • the stem density is preferably greater than 12 stems/cm 2 , and more preferably greater than 15 stems/cm 2 .
  • Table I presents specific stem density examples of 50, 149 and 357 stems/cm 2 , but stem web stem densities greater than 357 stems/cm 2 are also possible.
  • the surface stems may have a height gradient (e.g., shorter in center than near its ends) in order to facilitate handling, the stems may not be round in cross-section, and the stem density and/or stem spacing may vary. In some applications, it may even be desirable that adjacent stems have different heights, or to have stems which change in profile (i.e., cross-section) along their height (e.g., a cylindrical stem having an enlarged, tapered stem base).
  • Web 10 of the present invention is typically formed by molding a flowable material to form hooks 14 seen in Fig. 1 according to the techniques described in U.S. Pat. No. 5,077,870 (Melbye et al.) or stems as described in Application Serial No. 08/611,351 (Johnson et al.).
