Definitions
- This invention relates to a method and composition for producing a colored caulk to match a predetermined paint color.
- U.S. Patent No. 5,044,758, to Kurtz describes a machine for mixing pigment into bulk caulk.
- the bulk caulk is shipped in a jar whose lid incorporates a stirring blade for mixing the pigment with the caulk.
- Kurtz points out that the stirring blade is necessary because the typical apparatus used to mix paints by shaking is unsuitable for mixing pigment with commercial caulk due to the high viscosity of the latter.
- a motor is attached to the jar through an engaging means to effect mixing of the contents.
- the caulk is forced out of the jar by means of a piston that collapses the jar and transfers the contents to standard caulk tubes.
- This invention is directed to a method for producing a colored adhesive caulking material by the steps of: (a) providing in a resealable container a caulk forming composition which can be thickened by contact with a pigmented composition; (b) adding a pigmented composition of a predetermined color to the caulk forming composition in the resealable container; and (c) shaking the resealable container, thereby thickening the caulk forming composition to form a colored adhesive caulking material.
- the resealable container is shaken on a vibratory mixer.
- the invention is also directed to a caulk forming composition
- a caulk forming composition comprising an aqueous polymeric resin, a plasticizer, a surface modifying agent, a filler and a pH modifier; and to an adhesive colored caulking material produced by the method of this invention.
- This invention is further directed to a modified paint shaker jig useful in the method of this invention.
- the jig is capable of holding tubular containers and being mounted in a paint shaker.
- Figures 1 A and IB are side cross-sectional and bottom views, respectively, showing the construction of a plunger with a removable "T" handle and a twist and lock attachment.
- Figures 2A and 2B are side cross-sectional and bottom views, respectively, showing the construction of a plunger with a removable "T" handle and a threaded attachment system.
- Figure 3 is a side cross-sectional view showing a modified paint shaker jig positioned in a top-mounted paint shaker.
- Figure 4 is a side cross-sectional view showing the modified paint shaker jig positioned in a side-mounted paint shaker.
- Figures 5A and 5B are bottom and cross-sectional views, respectively, of the top section of the modified paint shaker jig.
- Figures 6A and 6B are bottom and cross-sectional views, respectively, of the bottom section of the modified paint shaker jig.
- a resealable container is partially filled with a caulk forming composition of low viscosity relative to a typical caulking material.
- the viscosity of the caulk forming composition is typically in the range from about 0.6-0.8 million centipoise.
- the container is sealed, preferably with a plunger fitted with a removable handle which allows the container to be opened and resealed at a wholesale or retail outlet.
- a pigmented composition preferably a water-based paint that has been premixed to match a predetermined color of the customer's choice, is added to the container, and the container is resealed, preferably by re-inserting the plunger and removing the handle.
- the container is then secured to a vibratory mixer, e.g., a standard or modified paint shaker, and shaken to mix the paint and the caulk forming composition. As the mixing is accomplished, the contents of the container thicken to form a colored adhesive caulking material..
- the container is then ready for use by the consumer in standard caulking equipment, e.g., a caulking gun.
- the resealable container employed in the present invention is any container which may be opened to add the pigmented composition and then resealed for mixing.
- the container must be resistant to the vibrations encountered during mixing.
- Suitable containers include without limitation paint cans with resealable lids, and standard caulk tubes with plungers.
- the container is a standard caulk tube.
- a removable handle is attached to the plunger.
- a variety of means for attaching such a removable handle will be apparent to those skilled in the art.
- the means of attachment include, without limitation: (1) manufacture of the plunger and handle as a single piece of material which can be broken near the plunger section by twisting, thereby removing the handle from the plunger; (2) threading the handle into a socket on the plunger; and (3) utilizing a "twist-and-lock" mechanism to allow easy attachment and removal of the handle.
- Figure 1 illustrates a preferred embodiment of the invention in which a plunger with a removable "T" handle and twist and lock system of attachment is employed. The narrow end of handle 2 engages with socket 4 on plunger 6.
- Handle 2 is twisted to lock it into plunger 6.
- This construction allows easy removal of the plunger using the "T" handle when the paint is to be added.
- the cross-sectional view of Figure 1 A shows the handle in the locked position; the handle would be rotated 90° to the unlocked position. The plunger may then easily be replaced, sealing the paint and caulk forming composition into the container, and the handle removed from the plunger by twisting the handle to disengage the handle from the plunger, and then sliding the handle out of the plunger.
- the bottom view of Figure IB shows the plunger without the handle.
- Figure 2 illustrates the construction of a plunger with a removable threaded "T" handle. Threads on the narrow end of handle 2 engage a threaded socket 4 on plunger 6.
- This invention also includes a modified paint shaker jig designed to accommodate resealable tubes in which the colored adhesive caulking material of this invention is produced.
- the jig is of a size and shape suitable for mounting in a paint shaker, and comprises a first section and a second section. Each section is constructed as a single piece by molding, casting, or drilling out a solid piece; or alternatively, by assembling sheets of material, e.g., metal or plastic.
- the first section comprises a substantially cylindrical frame having a first outer surface and a first inner surface; wherein the first inner surface has a plurality of first openings for holding tubular containers, e.g., standard caulk tubes.
- the first outer surface, the first inner surface, and the first openings are substantially circular.
- the second section comprises a substantially cylindrical frame having a second outer surface and a second inner surface; wherein the second inner surface has a plurality of second openings for holding tubular containers.
- the second outer surface, the second inner surface, and the second openings are substantially circular.
- the first section and the second section fit together to form a substantially cylindrical j ig capable of holding a plurality of tubular containers.
- the first openings are of substantially equal size, and the second openings are of substantially equal size. It is further preferred that each of the second openings has a diameter substantially equal to that of each of the first openings, and that the outside diameters of the first and second sections are substantially equal. In the same preferred embodiment, the jig has an outside diameter from about 6 2 inches to about 6% inches.
- the jig has an outside diameter approximating that of a standard one-gallon paint can, i.e., about 6 and 9/16 inches; the first openings have a diameter that will accommodate a standard caulk tube, i.e., from about 1.875 inches to about 1.925 inches; and the second openings also have a diameter from about 1.875 inches to about 1.925 inches. It is further preferred that there is a substantially circular interior surface below the second surface, and that the interior surface has substantially circular openings of substantially equal size that will accommodate the nozzle of a standard caulk tube, i.e., from about 0.625 inches to about 0.65 inches. Preferably at least one of the jig sections bears at least one brace on the outside curved surface to facilitate mounting the jig in a top-loading paint shaker.
- FIG. 3 A preferred embodiment of the modified paint shaker jig, in which the jig has been molded or cast as a single piece, is shown in Figure 3 mounted in a top-mounted paint shaker.
- Figure 4 shows the same jig as mounted in a side-mounted paint shaker.
- each section of the jig is constructed as a single molded or cast piece.
- the top section of the modified paint shaker jig is shown in Figures 5A and 5B.
- the inner surface 2 has several circular openings 4.
- a brace 6 to facilitate mounting in a top-loading paint shaker is attached to each side of the top section.
- the cross-sectional view in Figure 5B shows the sleeves 8 extending from the openings 4 to support caulk tubes.
- a circular flange 10 extends from surface 2.
- the top section is shown in Figure 5B with one caulk tube in place.
- Figure 6A is a top view of the bottom section of the modified paint shaker jig.
- the inner surface 2 has several circular openings 6.
- An additional surface 4 below inner surface 2 has several circular openings 8 which are smaller than openings 6.
- Figure 6B shows sleeves 12 extending through both surfaces, 2 and 4.
- Surface 10 provides seating for the flange on the top section when the two sections are joined to form the complete paint shaker jig.
- the caulk forming composition employed in this invention is of lower viscosity than a conventional adhesive caulking material. This lower viscosity allows the caulk forming composition to be mixed with the pigmented composition by shaking.
- Conventional adhesive caulking material has a much higher viscosity and high-shear mixing is required to blend the caulk with a pigmented material.
- the caulk forming composition is an aqueous mixture comprising a polymeric resin, a plasticizer, a surface-active agent, a filler, and a pH modifier.
- the caulk forming composition also contains one or more of a biocide, a thickening agent, and a glycol solvent.
