Disposable Caulk Smoother
A disposable hand tool for easily smoothing or spreading of material made for the filling of gaps or the sealing of two adjacent surfaces. The tool consists of a depressor made of plastic or cut wood surround on one end by cellular foam forming the smoothing head, while the depressor extends beyond the foam to form the handle. The depressor provides necessary reinforcement and stability to the foam, in order that when the surface of the cellular foam makes contact with the caulking material, enough rigidity is provided to transfer pressure as applied variably by the user with the handle to smooth the caulking material, but the pliability of the foam accommodates and flexes to variances in the surfaces being joined or filled by the caulking material. When finished using, the tool can be disposed of, or in some instances cleaned using appropriate process for removal of excess material being smoothed, and reused.
This invention relates to other tools in the prior art that are used for the smoothing and spreading of dispensed fluid materials that provide for the filling of gaps or the sealing of cracks between two adjacent surfaces, commonly referred to as caulk. Issues with the current state of technology are they are not designed to be disposable, so effort must be applied to clean them so they can be reused. For example U.S. Pat. No. 7,127,769 (Chang and Lee), D634,600 (Gringer, Soled, and Cheng), and D606,375 (Divita). This issue also includes the common use of a human digit of the hand, the caulking soils the digit, and the soiled digit needs to be cleaned, as an un-cleaned digit transfers the dirt and soil to other materials being worked with. Some forms of the prior art must be held at a specific angle or a specific side to be effective. In addition, some forms of the current state of technology or prior art are also rigid, so they do not accommodate well the slight variances in the material being filled or sealed, could damage more delicate surfaces, or catch on minor splinters of wooden surfaces.
BRIEF SUMMARY OF THE INVENTIONThe disposable hand tool is comprised of a depressor made of injection molded plastic or cut wood surround on one end by closed cell foam smoothing head, while the depressor extends beyond the foam to form the handle. The depressor has the appropriate shape within the foam head to provide necessary reinforcement and stability to the foam, in order that when the surface of the cellular foam smoothing head makes contact with the caulking material, enough rigidity is provided to transfer pressure as applied variably by the user with the handle to smooth the previously dispensed caulking material. The pliability of the foam head accommodates and flexes to variances in the surfaces being joined or filled by the caulking material, the foam smoothing head is effective from a number of angles, and can be turned over if caulking material collects on one side being used, or easily wiped clean. This invention improves on the prior art in that it is very simple and easy to use. It is disposable so while cleanable, particularly with latex based caulking material, does not have to be cleaned after use, and prevents fingers of the hand from becoming soiled by the caulking material. The cellular foam smoothing head is pliable so more readily adapts to variance in material surfaces, thus avoiding potential damage to more delicate surfaces and the catching of wood splinters. The foam smoothing head is also effective from a number of angles and sides. If caulking material collects on one side of the tool, it can be turned over and the other side used, or easily wiped clean if desired.
In a preferred form, the depressor widens to a rounded triangular or arrow shape encased in a conical foam head, the shape of the depressor stick within the foam secures the depressor within the foam smoothing head, and also provides rigidity for the transfer of pressure from the handle. In an alternate preferred form, the depressor and foam head is wider and flatter to accommodate flat surfaces. In any preferred form the foam smoothing head provides a surface for smoothing the previously dispensed caulking material, adapts to variances in the surfaces being sealed or filled, avoids the possibility of damage or gouging the surfaces being joined, can be turned over and another side used if one side collects too much caulking, and it eliminates the need to clean after use by being disposable, but the composition is such that it can be easily cleaned if desired. The tool is simple to use.
