Definitions

  • This invention relates to a multi-layered bulletin board, more particularly to a bulletin board having a stack of bulletin holding sheets to permit adhesion of a bulletin thereon.
  • a conventional bulletin board as shown in Figure 1, generally includes a bulletin body 12 and a frame 11 surrounding the bulletin body 11.
  • the bulletin body 11 is typically made of a magnetically attractive metal, a wooden material or a cork material.
  • positioning members 13, such as magnets or thumb pins, are required for positioning a bulletin 14 on the bulletin body 12.
  • the conventional bulletin board suffers from the following drawbacks:
  • the object of the present invention is to provide a multi-layered bulletin board that includes a stack of bulletin holding sheets to permit adhesion of a bulletin thereon.
  • the multi-layered bulletin board of the present invention includes a stack of bulletin holding sheets, each of which has a first surface which is applied with a pressure-sensitive adhesive that forms an adhesive layer adapted to permit removable and repositionable adhesion of a bulletin thereon, and an opposite second surface applied with a release agent that forms a release layer and that is adhered removably to the adhesive layer of an adjacent one of the bulletin holding sheets.
  • the preferred embodiment of the multi-layered bulletin board 2 of the present invention is shown to include a stack of bulletin holding sheets 21 and a cover sheet 214.
  • Each of the bulletin holding sheets 21 is made of a foamed material, paper or a plastic material, and has a first surface which is applied with a pressure sensitive adhesive that forms an adhesive layer 211 for posting a bulletin 3 thereon.
  • the bulletin 3 has its inner surface entirely adhered to the adhesive layer 211 of an outermost one of the bulletin holding sheets 21.
  • the adhesive layer 211 is made from a pressure sensitive adhesive, the bulletin 3 can be adhered thereto removably and repositionably as desired.
  • Each of the bulletin holding sheets 21 further has a second surface opposite to the first surface and applied with a release agent that forms a release layer 213 which is adhered removably to the adhesive layer 211 of an inner adjacent one of the bulletin holding sheets 21.
  • the bulletin holding sheets 21 are further provided with a plurality of caps 212 of substantially triangular shape, which are fitted to the aligned corners of the bulletin holding sheets 21, respectively, to shield the adhesive layers 211 of the bulletin holding sheets 21 so as to prevent the bulletin holding sheets 21 from adhering to one another at the corners. As such, the bulletin holding sheet 21 can be easily separated from adjacent bulletin holding sheets 21.
  • the cover sheet 214 (shown in phantom line in Figure 2) is adhered removably to the adhesive layer 211 of the outermost one of the bulletin holding sheets 21 before the multi-layered bulletin board 2 is used so as to protect the adhesive layer 211 of the outermost bulletin holding sheet 21 from being contaminated by dust and losing its tackiness.
  • the bulletin board 1 may be fixed to a wall by means of a fastener, an adhesive, etc.
  • the cover sheet 214 is first removed from the outermost bulletin holding sheet 21.
  • a bulletin 3 is posted to the adhesive layer 211 of the outermost bulletin holding sheet 21 at a predetermined location.
  • the bulletin 3 can be repeatedly adhered to and removed from the outermost bulletin holding sheet 21 as desired.
  • the adhesion property of the outermost bulletin holding sheet 21 diminishes owing to repeated use and presence of contaminants, the used outermost bulletin holding sheet 21 is removed to expose the adhesive layer 211 of an inner adjacent one of the bulletin holding sheets 21.
  • the outer one of the bulletin holding sheets 21 may be removed by handling the cap 212 provided on the corner of the outer bulletin holding sheet 21.
  • the caps 212 facilitate removal of the used bulletin holding sheets 21.
  • the bulletin holding sheets 21 of the multi-layered bulletin board 2 of the present invention may be designed to have different patterns thereon so that a different visual effect is presented whenever the used bulletin holding sheet 21 is removed to expose an inner adjacent one of the bulletin holding sheets 21.
  • each of the bulletin holding sheets 21 is provided with the adhesive layer 211 for removable and repositionable adhesion of the bulletin 3 thereto, positioning members for positioning the bulletin 3 on the bulletin board are not required.
  • each of the bulletin holding sheets 21 is removably adhered to an inner adjacent one of the bulletin holding sheets 21, the bulletin board 2 can always maintain a clean and fresh appearance even after a long period of use.
  • each of the bulletin holding sheets 21 can be easily removed from the inner adjacent one of the bulletin holding sheets 21.
