The present invention relates to index tabs, and more particularly to a pad of sheets that each have one or more removable index tabs thereon.
Adhesively backed index tabs are known in the art. The tabs typically have a coating of removable or permanent pressure sensitive adhesive on the back, such that the tab may be placed on the edge of the page or other substrate. The tabs may be used, for example, to mark a page in a book. A tab may have a portion that extends beyond the edge of the page, to identify the page that is marked. The tab may have a writable portion, such that the user can write or print text and/or graphics.
Index tabs of this type are typically supplied on a sheet, from which the user may remove the index tabs as desired. The sheets are typically U.S. letter size or similar and are not always convenient to store due to the relatively large size. Alternatively the tabs may be supplied affixed to sheets of a pad. A sheet of tabs that is removed from a pad is often easily misplaced because it is thin. Alternatively, the tabs may be supplied in a dispenser, with the user pulling the tabs from the dispenser as needed. The dispensers are typically small and easily misplaced or somewhat bulky such that they cannot be conveniently kept where most needed.
According to one aspect of the present invention, a pad of index tabs includes a plurality of sheets, each sheet comprising an area of removable adhesive. The sheets are applied to one another at respective areas of removable adhesive to form a pad. Each sheet has at least one index tab removably affixed thereto.
The areas of removable adhesive may be on the back of the sheet. Each sheet may include a plurality of removable tabs, with the removable tabs adhered to the sheets. The removable tab may include a writing surface, with the tabs partially backed with adhesive. The writing surface may, for example, be paper. In another embodiment, the index tabs may include a polyester base and a paper writing area, the paper writing area being adhered to the polyester base.
The pad may be backed with a backing sheet. The adhesive area may be a strip of adhesive at a top edge of the sheet. The sheet may be a release liner coated on the front side thereof with a release coating. Optionally, the sheet may lack a release coating or may be transparent. The tab may be partially coated with adhesive, each said tab having an edge portion thereof that is not coated with adhesive.
According to another aspect of the present invention, a pad of index tabs includes a plurality of sheets, each sheet comprising a front and a back, and an area of removable adhesive along a top edge of the back. The sheets are applied to one another at respective areas of removable adhesive to form a pad. Each sheet has a plurality of index tabs removably adhered thereto. The tabs are partially coated with removable adhesive and have an edge portion that is not coated with adhesive. Each of the tabs has on an edge thereof a writing surface.
The invention includes various features and modifications that are apparent from a study of the Detailed Description, the Drawings, and the claims. Consequently, this Summary does not limit the scope of the invention.
Each sheet 12 has on the back thereof a stripe of adhesive 16. The stripe of adhesive 16 serves to hold the sheet 12 to the rest of the pad and also allows individual sheets to be affixed to another surface once they are separated from the pad. The preferred embodiment includes a single stripe of adhesive at the upper edge 16, although it may alternatively include a stripe along another edge, or an additional stripe of adhesive elsewhere on the sheet, such as at the center of the sheet. Various other adhesive arrangements may be utilized, such as printing the adhesive in a pattern, rather than in a stripe or other multiple location configurations.
When release coated paper is used to form the sheet 12, the release coating is typically on the upper face on which the index tabs 14 reside. The back as shown in
A layer of pressure sensitive adhesive 20 serves to bond adjacent sheets 12 together. A backing sheet 22 may define the bottom of the pad. The backing sheet may be a sheet of paper, or may be a stiffer sheet material, such as card stock or card board.
The individual sheets, such as 12A, may be removed from the pad and adhered to other surfaces. For example, in
It is noted in
It is noted that various alternatives and modifications may be made within the scope of the invention. For example, the sheet 12 may be made with a transparent material, such as polyester. A sheet 12 may be coated with a release coating, such as silicone, although the sheet 12 may alternatively have a smooth surface that is sufficient to allow tab 14 to be removed therefrom. The writable surface 16 is typically a paper material that is adhered to tab 14. However, the writable surface 16 may be provided initially in the form of a tape that is applied to the tab 14 or by the application of a receptive coating as is known in the art. The base material of the tab 14 may be substantially transparent polymer material, such as transparent polyester, or it may alternatively be many of a variety of other materials, such as paper, various polymers, cardstock, or numerous other materials.
The sheets in
As a further alternative, the index tabs, flags, labels or other items affixed to the sheets may be color coded or otherwise provided in a variety of colors. For example, the writable surfaces of the index tabs may be colored, with each tab having a unique color.
While the specification describes particular embodiments of the present invention, those of ordinary skill can devise variations of the present invention without departing from the inventive concept.
