AI Technical Summary

Benefits of technology

The invention is a better plug used to repair holes in plasterboards. It has a conical shape with a conical side wall and a circular cross-section. The plug has recesses on its side wall which can be longitudial or spiral. The angle of the conical tip can range from 0,25 degrees to 8 degrees. This improved plug design is easier to use and more effective in sealing plasterboards.

Problems solved by technology

However, using joint material for filling cracks or holes can often be tedious as the material shrinks upon drying and several layers are often required which must be allowed to dry in between applications.

Embodiment Construction

[0022]The conical repair plug of the invention comprises gypsum plaster or materially similar material (chalk or chalk-like material including in particular conventional gypsum plaster (hydrated calcium sulfate) but can also be from calcium carbonate, magnesium carbonate, magnesium silicate, etc.). The term ‘chalk-like material’ is used herein to describe solid, typically porous or semi-porous material, which can be readily filed or sanded down. Accordingly, the term also encompasses other material that fulfils this functional criterion, including but not limited to polymeric material, e.g. PVC-based polymer clay, cement material, and any mixtures of the above-mentioned materials. In certain embodiments polystyrene or similar plastic polymer material is used in the plug.

[0023]The plug of the present invention has a substantially conical shape with a longitudinal axis extending between a front end 3 and a back end 4, the front end having a more narrow circumference than the back end....

Abstract

A repair plug for sealing holes in plasterboards is provided. The repair plug has gypsum plaster or the like material, substantially a conical shape with a longitudinal axis extending between a front end and a back end, a conical side wall, and recesses on the side wall. The recesses are either longitudinal or spiral around the cylindrical side walls.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of U.S. Provisional Application No. 61 / 984,570 filed on Apr. 25, 2014 under 35 U.S.C. §119(e), the entire contents of which are hereby incorporated by reference.TECHNICAL BACKGROUND[0002]Plasterboard, also referred to as drywall, gypsum board or sheetrock (proprietary name of United States Gypsum Company) is a common standard material for interior walls and ceilings in modern buildings. Plasterboard is made primarily from gypsum plaster, the semi-hydrous form of calcium sulphate (CaSO4•½H2O), typically mixed with additives such as fiber and mildew and fire resistance agents, which is sandwiched between two sheets of heavy paper or fiberglass mats. When the core sets and is dried, the sandwich becomes rigid and strong.[0003]It is easy to cut the plasterboards and make holes through them, e.g. for cords and pipes that have to cross the walls or ceilings being formed by the boards.[0004]Methods for repairing ...
