Anti-moisture floor tile

#1. Field of the Invention

#A type of floor tile, particularly with the surface attached to the floor being ragged, and coating with adhesive on the raised portion of the ragged surface.

#2. Description of the Background Art

#FIG. 1 is a partially cross-sectional view of the present invention;

#FIG. 2 is a partially enlarged view of FIG. 1;

#FIG. 3 is a cross-sectional view according to another embodiment of the present invention.

#A type of floor tile according to the invention is shown as FIGS. 1 and 2. As a normal plastic floor tile, such as the foaming plastic floor tile, the printed adhesive floor tile, the bottom is formed as a ragged surface 10. The ragged surface 10 may be a cross-section 12 as shown in the figure, and also possibly be of any regular shape or irregular shape, and of continuous or discontinuous cross-section. The downward raised surface 14 on the ragged surface 10 is coated with the adhesive 16 in advance, in which the type of the adhesive 16 is preferably a type of pressure-sensitive glue for repeatedly detachable function for the floor tile. The floor tile 1 is adhered on the floor 2 by the adhesive 16, and in a view of the cross-section after the adhesion, the floor tile 1 and the floor 2 exhibit gaps 18 in-between by the ragged surface 10. With the plurality of gaps 18 in presence at the bottom of the floor tile 1, the moisture generated from the floor 2 may be flowing within the space that it will not be accumulated between the floor 2 and the adhesive 16 for chemical reaction with the adhesive 16 and causing the adhesion failure for the adhesive 16.

#The present invention can not only form the above-mentioned embossment on the ragged surface 10 at the bottom of the floor tile, but also provide another method for forming the ragged surface, which is to coat the adhesive 32 on the planar surface of the floor tile 3. The coating for the adhesive 32 is applied partially, that is, by partially coating with the adhesive 32 but others not. And, the adhesive 32 must at least have a certain depth, such as above 0.5 mm, so that the height difference between the formed coating depth and the bottom 34 of the floor tile 3 is formed as the desired gap 36 in the present invention. The invention uses the method for coating the bottom of the floor tile with the adhesive, wherein the coating area can be regular or irregular and the coating path may be continuous or discontinuous.
