Definitions

  • Signs and other visual displays such as bulletin boards and message boards are frequently used by industry and retail providers as well as individual consumers.
  • removal and reuse or repositioning of the display is usually difficult, if not impossible.
  • removal of the display often causes damage to the surface on which the display is mounted.
  • bulletin boards, signs and similar items are typically hung by means of a hook or wire attached to the item and secured with a nail or a screw to the surface on which the item is to be mounted. Removal, while relatively simple and causing no damage to the display item, leaves the underlying surface marred by the nail or screw (or the hole left upon removal of the nail or screw).
  • Pressure-sensitive permanent adhesives have also been used to facilitate mounting of visual display items.
  • a substrate is coated on both sides with a permanent adhesive, and one side is contacted with the item to be mounted. The other side of the substrate is applied to the surface on which the item is to be mounted.
  • these compositions have several limitations.
  • the adhesive may not stick to all mounting surfaces, and the permanency of the adhesive makes removal from either the item or the mounting surface highly damaging to both the surface and the adhesive substrate, rendering reuse an impossibility.
  • U.S. Patent No. 4,671,003 discloses a pressure-sensitive, adhesive-backed information-conveying sign which is removable and reusable.
  • the adhesive-backed sign contains an adhesive-free zone contained entirely within the perimeter of the sign which may be grasped to remove the sign from the surface to which it has been applied.
  • the sign can optionally be reapplied to another surface, as long as the adhesive retains sufficient adhesiveness to permit reapplication.
  • the present invention pertains to an adhesive mounting system which allows for easy removal and repositioning of items mounted therewith.
  • the invention also pertains to display items comprising or mounted with the adhesive mounting system of the present invention, as well as to methods for making the adhesive mounting system.
  • the adhesive mounting system of the present invention comprises multiple (i.e., more than one) composite layers.
  • Each individual composite layer comprises a substrate having a first or back side coated with a removable adhesive and a second or front side coated with a releasing agent; the composite layers are arranged such that the removable adhesive of one composite layer is in contact with the releasing agent of another composite layer.
  • the multiple composite layers are "stacked" such that all the releasing agent-coated substrate sides face in one direction and all the adhesive-coated substrate sides face in the opposite direction.
  • the adhesive portion of the outermost layer can optionally be covered with a backing sheet prior to mounting to prevent contamination of the adhesive which would result in a loss of adhesiveness.
  • the adhesive mounting system of the present invention is applied to the back (or mounting side) of a display item by means of an adhesive, and more preferably by a permanent adhesive.
  • the adhesive mounting system is applied to the display item such that the front side of each composite layer (i.e., the side which is coated with the releasing agent) faces the display item and the adhesive-coated side faces away from the item (see Figure 2).
  • the releasing agent-coated side of the innermost composite layer is attached to the mounting side of the display item by means of an adhesive, leaving the removable adhesive-coated side of the outermost composite layer free to contact the surface to which the item is to be mounted.
  • display items which are mounted with the adhesive mounting system of the present invention can be freely relocated (i.e., reused) at another position without causing damage to either the display item or to the surface to which it has been mounted.
  • This objective is achieved by the layered configuration of the adhesive system.
  • the outermost composite layer of the adhesive system which is in contact with the surface to which the item is mounted, is separated from the adjacent composite layer at the interface between the releasing agent of the outermost layer and the removable adhesive of the adjacent layer. This separation leaves a fresh, unused adhesive surface of the next composite layer available for contact with a new surface to which the display item can be mounted.
  • the adhesive mounting system of the present invention has utility in many applications.
  • the system can be used to mount display items such as signs, bulletin boards, message boards, bumper stickers, stickers, tags, labels, pictures or photographs, and items of art or decoration such as craft items, plaques and paintings.
  • the adhesive mounting system of the present invention is particularly advantageous for mounting display items in settings where the information to be conveyed is of a transient nature, e.g., sale prices or notifications, event information or warning or emergency information.
  • the described system allows the reliable conveyance of information without the expense of creating, affixing, removing and relocating a relatively permanent display, and further without damage to either the display item or the surface to which it has been mounted.
  • the present invention pertains to an adhesive mounting system, methods for making the adhesive mounting system, and display items comprising the system.
  • the adhesive mounting system 2 of the present invention comprises multiple (i.e., more than one) composite layers 5, 6, 7.
  • Each individual composite layer comprises a substrate 7 having a first or back side coated with a removable adhesive 5 and a second or front side coated with a releasing agent 6.
  • the composite layers are arranged such that the removable adhesive of one composite layer is in contact with the releasing agent of another composite layer.
  • the multiple composite layers are "stacked" such that all the releasing agent-coated substrate sides face in one direction and all the adhesive-coated substrate sides face in the opposite direction.
  • the adhesive portion of the outermost layer can optionally be covered with a backing sheet or cover sheet 8 prior to mounting to prevent spoiling of the adhesive.
  • the adhesive mounting system is attached to a display item 3 with an adhesive which is preferably permanent 9, and the display item mounted with the adhesive mounting system can be easily removed and repositioned as desired.
  • composite layer is intended to mean a layer which is assembled by coating one side of a substrate with a removable adhesive and the opposite side of the substrate with a releasing agent; the dual-coated substrate is referred to as a "composite layer".
  • Suitable substrates which can be coated with both removable adhesive and releasing agent as described herein include paper, foam, plastic and cardboard.
  • the substrate should be suitable for receiving a removable adhesive on one side and a releasing agent on the opposite side; for example, the substrate material should not be degraded or structurally weakened by contact with either the releasing agent or adhesive.
  • One side of the suitable substrate is coated with a removable adhesive; this side of the substrate is referred to herein as the "back" side of the substrate.
  • the back side of the substrate can be coated completely or in part with the removable adhesive, as long as the area and shape of the adhesive-coated portion is suitable for contacting and maintaining contact with the surface on which an item is to be mounted.
  • the configuration of adhesive on the substrate can be varied according to design preference; a preferred location of the adhesive is at least along one or more marginal edges of the substrate.
  • the coating of removable adhesive can be either uniform or non-uniform. such as in a striated pattern, thereby conserving the amount of removable adhesive required for adhering the display item to the surface to which it is to be mounted.
  • Suitable removable adhesives for use in the present invention include any adhesive which can be temporarily attached to one surface, removed from the surface without damaging the integrity of the surface from which it is removed, and then adhered to another surface of similar or different material.
  • acrylic adhesives are particularly useful in the invention.
  • Removable adhesives of the present invention are applied to the back side of the substrate as a coating, generally in an amount of from about 10 to about 25 grams per square meter.
  • the adhesive coating thickness, as well as area of application can be varied depending upon the adhesive strength of the particular adhesive used and the weight of the display item to be mounted. The skilled artisan will be able to readily determine the appropriate thickness and area of the adhesive coating based upon the adhesive strength of the particular adhesive, the display item to be mounted, and the surface on which the item is to be mounted.
  • the side of the suitable substrate opposite the adhesive-coated side is coated with a releasing agent; this side of the substrate is referred to herein as the "front" side of the subscrace.
  • the front side of the substrate can be coated completely or in part with the releasing agent; for example, the releasing agent can be applied only to the portion of the substrate which corresponds to the position of the removable adhesive on the adjacent composite layer.
  • Suitable releasing agents for use in the present invention are those which are not self-releasing but which require a pulling force in order to release them from the adhesive. Additionally, it is preferred chat the binding force between the releasing agent and the adhesive be less than the binding force between the adhesive and the surface to which the item is mounted; this allows the composite layers to separate at the releasing agent/adhesive interface rather than at the adhesive/mounting surface interface.
  • a material such as a silicone-based agent can be used in this invention.
  • Suitable releasing agents can also be selected from polypropylene. polyethylene, organic fluorinated compounds, acrylic polymers, polyvinylcarbamate, TEFLONTM or similar polymeric materials having a very low surface energy.
  • the individual composite layers described above are arranged such that the removable adhesive of one composite layer is in contact with the releasing agent of another composite layer.
  • the multiple composite layers are "stacked" such that all the releasing agent-coated substrate sides face in one direction and all the adhesive-coated substrate sides face in the opposite direction.
  • the number of composite layers which are stacked together determines the number of times the display item can be repositioned; for example, an adhesive mounting system comprising five composite layers allows the display item to be repositioned or reused five times, as each removal/repositioning expends one composite layer. When the final composite layer is used to mount the item, the item can no longer be repositioned, although it can be removed from the surface to which it is mounted.
  • the number of composite layers which can be stacked together ranges from about 2 to about 20, with from about 5 to about 7 being preferred.
  • the number of composite layers included in the stack should be an amount which will not cause the display item to fall off the surface to which it is mounted or to cause self-release at the releasing agent/adhesive interface; thus, the number of appropriate composite layers depends upon the item to be mounted, the surface to which it is to be mounted, and the strength of the adhesive used.
  • the adhesive portion of the outermost layer can optionally be covered with a backing sheet prior to mounting to prevent contamination of the adhesive.
  • This cover sheet is composed of a material, e.g., polyethylene, polypropylene or TEFLONTM, which protects the underlying adhesive-coated side of the substrate prior to mounting and which is removable to provide a fresh, unused adhesive surface.
  • the backing sheet can be a silicone-treated paper.
  • Such backing sheets, also known as release papers, are known in the art and will be readily apparent to the skilled artisan.
  • the adhesive mounting system of the present invention is applied to the back (or mounting side) of a display item by means of an adhesive, and more preferably by a permanent adhesive.
  • the adhesive mounting system is applied to the display item such that the front side of each composite layer (i.e., the side which is coated wich the releasing agent) faces the display item and the adhesive-coated side faces away from the item (see Figure 2).
  • the optional cover sheet protecting the outermost adhesive layer is removed. and the display item is then mounted to an appropriate surface (see Figure 1).
  • the releasing agent-coated side of the innermost composite layer is attached to the mounting side of the display item by means of an adhesive, leaving the removable adhesive-coated side of the outermost composite layer free to contact the surface to which the item is to be mounted.
  • the adhesive mounting system of the present invention can be attached to a display item (e.g., by a manufacturer) either during or at the end of the display item manufacturing process.
  • the adhesive mounting system can be attached to a display item by a consumer after separately obtaining the display item and the adhesive mounting system.
  • the consumer attaches the adhesive mounting system to the display item by means of a permanent adhesive, such as rubber-based adhesives, e.g., rubber cement, or polyvinyl alcohol or acrylic latex.
  • a permanent adhesive such as rubber-based adhesives, e.g., rubber cement, or polyvinyl alcohol or acrylic latex.
  • the invention also pertains to a kit comprising the adhesive mounting system of the present invention and a suitable permanent adhesive; such a kit can be utilized by a consumer to mount items using the adhesive mounting system of the present invention.
  • Display items according to the present invention include, but are not limited to, signs, bulletin boards, message boards, removable and repositionable notepads, bumper stickers, stickers, tags, labels, pictures or photographs, and items of art or decoration such as craft items, plaques and paintings.
  • the display item can be composed of virtually any material, including, for example, wood, plastics (polyvinylchloride, cellulose, acetate, methylmethacrylate and polycarbonate), fabric, metal. paper, ceramics and glass.
  • Figure 2 illustrates one embodiment of the invention wherein a removable and repositionable notepad is attached to the adhesive mounting system of the present invention.
  • the notepad can be directly attached to the adhesive mounting system (not shown) or can be attached to a substrate or display item which is in turn attached to the adhesive mounting system ( Figure 2).
  • display items which are mounted with the adhesive mounting system of the present invention can be freely relocated (i.e., reused) at another position without causing damage to either the display item or to the surface to which it has been mounted.
  • This objective is achieved by the layered configuration of the adhesive system.
  • the outermost composite layer of the adhesive system which is in contact with the surface to which the item is mounted, is separated from the adjacent composite layer at the interface between the releasing agent of the outermost layer and the removable adhesive of the adjacent layer. This separation leaves a fresh, unused adhesive surface of the next composite layer available for contact with a new surface to which the display item can be mounted.
  • Appropriate surfaces on which the display items comprising the adhesive mounting system can be mounted will be easily recognized by the skilled artisan. These surfaces include natural and synthetic materials. including, but not limited to, wood, paper, plaster, plastic, glass, fabric and metals.
  • the display items can be mounted to doors, windows, walls, furniture, aucomobiles, shelves and counters.
  • display items comprising the adhesive mounting system of the present invention can be mounted in any orientation, including vertically (such as on a door) and horizontally (such as on a desktop or countertop) on both the top or upward facing and bottom or downward facing surfaces of a display.
  • the present invention also pertains to methods for making the adhesive mounting system of the present invention.
  • Methods for making an adhesive mounting system according to the present invention comprise the steps of applying a releasing agent to a front side of an appropriate substrate, applying a removable adhesive to a back side of the substrate to produce a composite layer, and assembling multiple composite layers such that the removable adhesive of one composite layer is in contact with the releasing agent of another composite layer.
  • Methods of applying both the removable adhesive and the releasing agent are well known in the art and include, for example, screen coating and roll coating.
  • the skilled artisan will readily be able to select a suitable substrate, depending upon the ultimate application of the adhesive mounting system.
