ABSTRACT:
DESCRIPTION
1. Technical Field
The present invention relates generally to devices which are capable of securing an object to a ferris surface, and more particularly, to magnetized securing devices having a non-permanent adhesive for removably securing an object thereto.
2. Background of the Invention
Magnetic devices are typically utilized to secure objects to ferris or other magnetically attracting elements. Several different types of magnetic devices exist, including: magnetic post cards, magnetic calenders, image containing magnets, magnetic ledger cards, magnetic holders, magnetic signs, etc . . . Numerous patents have been obtained for each of these different applications.
U.S. Pat. No. 5,699,956 issued to Brennan discloses a magnetic novelty card incorporating an outer plastic laminated to a thin paper-stock postcard containing a photograph or other image, a permanent adhesive layer connecting the postcard to one side of a sheet magnet, and another permanent adhesive layer connecting the other side of the sheet magnet to a paper backing for writing a note and addressing the post card. Accordingly, the postcard and paper backing are permanently connected to the magnet.
U.S. Pat. No. 5,893,586 issued to McGuire discloses a combination greeting card and calendar. The calendar has a magnetic fastener permanently attached to its back panel with a permanent adhesive for securing the calendar to a metal surface.
U.S. Pat. No. 5,799,423 issued to Malino discloses a perpetual magnetic calendar. Magnetic pieces magnetically adhere to a grid-like front surface of a calendar body. The magnetic pieces may include a feature such as indicia, an occasion, or a holiday affixed to a front surface thereof. The magnetic pieces are constructed of a strip magnet which is adhered by a pressure-sensitive permanent adhesive to a paper sheet. The paper sheet contains the indicia or other writing and may be laminated on its front and backside by a first and second transparent laminae. U.S. Pat. No. 4,176,478 issued to Brewer also discloses a perpetual calendar having blocks for the dates, months, year, etc. . . . Each block generally comprises a strip of magnetic tape permanently secured to the back of the indicia carrying block for magnetically affixing the block to the calendar front. Accordingly, like the previous disclosures, the indicia carrying material in each of these patents is permanently connected to the magnet.
U.S. Pat. No. 5,891,826 issued to Tsaur et al. discloses a method for affixing a thermal dye transfer image to a magnetic substrate. The process includes laminating a imaged intermediate dye-receiving element in face-to-face contact with a heat-activatable permanent adhesive layer to a magnetic substrate.
U.S. Pat. No. 3,627,626 issued to Chao discloses a magnetic ledger card and a method for forming the same. The final product includes a solvent based adhesive between a paper-base card and a magnetic tape. After a short setting period, the adhesive becomes permanent, thereby permanently affixing the paper-base card to the magnetic tape.
As explained above, each of these devices generally comprises a magnet with a permanent adhesive which allows an object to be fixedly attached to the magnet. The Assignee of the present application currently manufactures a product utilizing a similar means under the trademark “MagTabs”™. The MagTabs™ product comprises a flexible magnetic sheeting with a permanent adhesive attached to one surface of the magnetic sheeting. An object, such as a picture, photograph, piece of paper, etc . . . is then permanently secured to the magnet via the permanent adhesive. In all scenarios, whether the object is a piece of paper, an image, or some other element, the object remains permanently fixed to the magnet. If one were to attempt to remove the object from the magnet, at least the surface of the object connected to the adhesive, and typically a greater portion of the object than merely the surface thereof, would become damaged or destroyed. As the object is removed from the magnet, the portion of the object connected to the adhesive remains secured to the adhesive and tears away from the object itself. Since the magnet is therefore not reusable, a new or different magnet must be utilized for each different object or application.
Accordingly, a non-permanent adhesive-backed magnetized securing device in accordance with the present invention provides an inexpensive and easily manufactured removable magnetic securing device which eliminates the drawbacks of the prior magnetic securing devices described above.
SUMMARY OF THE INVENTION
The non-permanent adhesive-backed magnetized securing device of the present invention allows for affixing and removing of objects from the adhesive portion of the device with minimal to no destruction or marring of the contacted surface of the object. Further, the device has a quantified reusable lifespan, as opposed to being limited to a single use.
According to one aspect of the present invention, the device comprises a base member and a non-permanent adhesive connected to a first surface of the base member. The base member has a second surface that exhibits magnetic characteristics and is capable of magnetically connecting the device to a magnetic attracting element. The non-permanent adhesive is capable of allowing objects to be removably attached to the device. The non-permanent adhesive is permanently affixed to the first surface of the base member. A removable carrier is removably connected to the non-permanent adhesive to protect the non-permanent adhesive before use of the device. Upon removal of the carrier, the non-permanent adhesive is capable of adhering to an object.
According to another aspect of the present invention, the device further includes a permanent adhesive between and permanently affixing the non-permanent adhesive to the base member. Additionally, a dividing layer is located between the permanent adhesive and the non-permanent adhesive such that the permanent adhesive is located on one side of the dividing layer and the non-permanent adhesive is located on the other side of the dividing layer.
According to another aspect of the present invention, the inner or first surface of the base member is not magnetized. Depending upon the embodiment utilized, either the permanent or the non-permanent adhesive covers the entire first surface of the base member.
According to another aspect of the present invention, the magnetized removable securing device for removably securing an object to the device includes a first member having a first surface and a second surface, a dividing member having a first surface and a second surface, a first adhesive between the first member and the dividing member, and a second adhesive attached to the first surface of the dividing member. The first adhesive permanently connects the first surface of the first member and the second surface of the dividing member. The second adhesive is a non-permanent adhesive which has an outer surface that is capable of removably connecting objects thereto. As such, objects removed from the outer surface of the second adhesive are not damaged by the non-permanent adhesive.
According to another aspect of the present invention, a device for removably affixing an object to an outer surface of the device includes a magnetic material, a sheet-form material, a permanent adhesive connecting one side of the sheet-form material to the magnetic material, and a non-permanent adhesive that is capable of removably affixing objects thereto attached to the opposing side of the sheet-form material. The non-permanent adhesive remains affixed to the sheet-form material. And, the magnetic material has a non-magnetized surface which contacts the permanent adhesive.
According to yet another aspect of the present invention, the device includes a first subassembly laminated to a second subassembly. The first subassembly comprises a magnetized sheet. The second subassembly comprises a separating layer having a permanent adhesive on a first surface thereof, and a non-perman
