The present novel concept broadly relates to the art of adhesive tape products and, more particularly, to a composite masking tape suitable for uniform application along a wall structure and a method of using the same.
The subject composite tape and method are well suited for uniformly masking a portion of a wall adjacent a feature formed therealong prior to the application of a treatment along the feature. One example of a suitable application includes applying the composite tape uniformly along two walls prior to laying a bead of caulk along a seam or joint formed therebetween, and the subject composite tape and method will be discussed in detail with particular reference thereto. However, it is to be distinctly understood that the subject composite tape and method are capable of broad use and that the discussion of this or other specific applications is merely exemplary and not intended to be in any way limiting.
Masking products, generally, are well know and commonly used in a wide variety of applications to mask an area prior to treatment, such as by painting or caulking. Applying a mask to an area prior to treatment of the remaining unmasked area is intended to prevent or at least minimize the inadvertent treatment of the area that is masked. Simply stated, the intended result is to cover the areas that are not to be treated. In practice, however, the achievement of this result is often difficult and time consuming. It is also desirable for the masking product be removable without undesirably affecting the masked area or the treated area adjacent thereto. Additionally, it is desirable for the masking material to be of a relatively low cost because the material itself, once applied to the area, typically becomes at least partially treated and is therefore not normally reusable.
One example of a masking product that is particularly well suited for such applications is single-layer masking tape formed from paper and having an adhesive disposed along one side. This type of product is of relatively low-cost and is, therefore, disposable. Additionally, such a product is typically easily removed from the masked area without undesirably affecting the same. One disadvantage of using a single-layer masking tape, however, is that the same can be difficult to apply uniformly, such as in a straight line, without a guide, such as an adjacent wall of a corner. For example, where a joint between two walls is to be caulked, such as in a bathtub surround or shower, for example, the masking tape is applied adjacent the joint without actually covering the same with the tape. Thus, the masking tape is normally applied in a freehand manner that can undesirably result in an unmasked treatment area that is not uniform, such as having uneven spacing and/or edges that are not straight.
One masking product that has been developed in an effort to overcome this difficulty is shown in U.S. Pat. No. 5,658,632 to Krabill. The '632 patent illustrates a masking tape that has perforations extending longitudinally therealong. The intention is to apply a single length of tape along the joint that is to be treated such that both sides thereof are masked. Then, the central portions can be torn away exposing the area that is to be treated while leaving a relatively uniform mask along the adjacent sides of the joint. There are numerous disadvantages to the product in Krabill, however. One such disadvantage is that the tape itself is still often applied without any sort of guide and in a generally freehand manner. Therefore, there are often portions of the tape that are not uniform or straight. Thus, the resulting unmasked space, while having a more consistent width, remains undesirably formed or applied along the feature. Another disadvantage is that tearing the central portions of the masking tape typically results in frayed paper from the perforations that extend inwardly toward the area to be treated. As such, the fraying can result in a non-uniform edge and, in caulking applications, the frayed paper can become embedded in the caulk. This can make removal of the masking product more difficult and can, in some cases, undesirably affect the appearance of the associated bead of caulk.
A composite masking tape in accordance with one embodiment of the present novel concept is provided and includes a first length of tape having opposing first and second sides and a first width defined between first and second longitudinally extending edges thereof. A first adhesive layer is deposited along the first side of the first length of tape. A second length of tape has opposing first and second sides and a second width defined between first and second longitudinally extending edges thereof. The second length of tape is disposed longitudinally along the first length of tape with the first side of the second length of tape adjacent the second side of the first length of tape. The second width is greater than the first width such that the first and second edges of the second length of tape respectively extend laterally outwardly beyond the first and second edges of the first length of tape. A second adhesive layer is disposed between the first and second lengths of tape such that the lengths of tape are secured to one another.
Another embodiment of a composite tape in accordance with the present novel concept is provided and includes a first length of tape having first and second sides and a first substantially uniform width. A second length of tape has first and second sides and a second substantially uniform width that is greater than the first width. A first adhesive layer is disposed along the first side of the first length of tape. A second adhesive layer is disposed along one of the second side of the first length of tape and the first side of the second length of tape. The second length of tape is disposed longitudinally along the first length of tape with the first side of the second length of tape adjacent the second side of the first length of tape such that the second length of tape forms opposing first and second longitudinally extending lateral overhangs with the first overhang having a greater lateral dimension than the second overhang.
A method of uniformly masking an associated wall feature formed between associated first and second wall portions, in accordance with the present novel concept, is provided and includes a step of providing a first length of composite masking tape. The first length of tape has a masking tape portion and an alignment tape portion extending longitudinally adjacent one another. The masking tape portion has a first adhesive layer disposed along a first side. A second adhesive layer is disposed opposite the first adhesive layer between the masking and alignment tape portions. The alignment tape portion has a greater width than the masking tape portion such that opposing alignment edges of the alignment tape portion extend laterally outwardly from the masking tape portion. Another step includes applying the first length of tape along the associated first wall portion adjacent the associated wall feature such that one of the alignment edges thereof is in substantial, alignment along the associated second wall portion. A further step includes removing the alignment tape portion from the first length of tape.
Another method of applying a length of masking tape uniformly along an associated wall feature formed between associated first and second wall portions, in accordance with the present novel concept, is provided and includes a step of providing a length of composite tape that includes a masking tape portion having a first adhesive layer deposited along a first side thereof and an alignment tape portion extending longitudinally along a second side of the masking tape portion with a second adhesive layer deposited between the masking tape portion and the alignment tape portion. The alignment tape portion having first and second alignment edges extending respectively laterally outwardly beyond first and second masking edges of the masking tape portion. The first alignment edge extends beyond the first masking edge a first distance, and the second alignment edge extends beyond the second masking edge a second distance that is different from the first distance. Another step includes selecting one of the first distance and the second distance for use along the associated wall feature. Still another step includes orienting the length of composite tape along the associated first wall portion adjacent the associated wall feature such that an alignment edge associated with the selected one of the first and second distances is adjacent the associated second wall portion. Still another step includes applying the length of composite tape along the associated first wall portion adjacent the associated wall feature with the selected alignment edge aligned along the associated second wall portion. A further step includes removing the alignment tape portion from along the masking portion such that the masking portion remains in place adjacent the associated wall feature.
Turning now to the drawings wherein the showings are for the purposes of illustrating exemplary embodiments of the present novel concept only and not for limiting the same,
Alignment tape portion 104 is oriented along masking tape portion 102 such that top surface 108 of the masking tape portion and bottom surface 114 of the alignment tape portion are adjacent one another. It is clear from
A first adhesive layer 126 is deposited or otherwise disposed along bottom surface 106 of masking tape portion 102. In one exemplary embodiment, first adhesive layer 126 is disposed evenly both longitudinally and laterally along bottom surface 106. In other exemplary embodiments, however, the adhesive layer can optionally be patterned or zone coated. A second adhesive layer 128 is shown in the exemplary embodiment in
Furthermore, a suitable release coating 132 can optionally be provided on top surface 116 of alignment tape portion 104. It will be appreciated that release coating 132 can be of the same or a different type or kind than coating 130 discussed above, and can be deposited or applied in any suitable manner. Release coating 132 may find particular utility where composite masking tape 100 is packaged in roll form. In which case, first adhesive layer 126 will be in contact with top surface 116 of the underlying wraps of the roll, and coating 132 will minimize the adhesion of layer 126 thereto. Also, it will be appreciated that in other arrangements adhesive layer 128 and coating 130, if provided, could, in the alternative, be deposited or otherwise disposed in an inverted arrangement (i.e., along surfaces of the opposing tape portions) without departing from the principles of the present novel concept.
Another exemplary embodiment of a composite masking tape 200 is shown in
Alignment tape portion 204 is disposed longitudinally along masking tape portion 202 such that top surface 208 of the masking tape portion is adjacent bottom surface 214 of the alignment tape portion. Additionally, it is clear from
A first adhesive layer 226 is deposited or otherwise disposed along bottom surface 206 of masking tape portion 202. In one exemplary embodiment, the first adhesive layer extends substantially uniformly along and across bottom surface 206. In other exemplary embodiments, however, a patterned or zone coated adhesive layer can optionally be formed. A second adhesive layer 228 is disposed between tape portions 202 and 204. It will be appreciated that second adhesive layer 228 can be deposited or otherwise disposed along either or both of surfaces 208 and 214, respectively, of tape portions 202 and 204. The second adhesive layer can be disposed either substantially uniformly along and across the corresponding surface, or alternately can be patterned, zone coated or otherwise applied in a discontinuous manner. Additionally, second adhesive layer 228 is shown in
Still another embodiment of a composite masking tape 300 is shown in
Alignment tape portion 304 is disposed longitudinally along masking tape portion 302 such that top surface 308 of the masking tape portion is adjacent bottom surface 314 of the alignment tape portion, which has a greater width than the masking tape portion. Longitudinally extending lateral overhang 322 is formed between edges 310 and 318, and longitudinally extending lateral overhang 324 is formed opposite overhang 322 between edges 312 and 320.
Similar to the embodiment shown in
Composite masking tape 300 also includes a first adhesive layer 326 deposited or otherwise disposed along bottom surface 306 of masking tape portion 302. In one exemplary embodiment, the adhesive layer extends substantially uniformly along and across bottom surface 306. In other embodiments, however, a patterned, zone coated or other discontinuous adhesive layer can optionally be used. A second adhesive layer 328 is disposed between tape portions 302 and 304. It will be appreciated that second adhesive layer 328 can be deposited or otherwise disposed along either or both of surfaces 308 and 314, respectively, of tape portions 302 and 304. Rather than extending between edges 310 and 312, second adhesive layer 328 is disposed inwardly of the edges forming a securement area 330 between respective adhesive relief areas 332 and 334 disposed therealong. In the embodiment shown in
One advantage of providing an adhesive relief area, such as one or both of relief areas 332 and 334, for example, is that such areas help to prevent the inadvertent lifting of the longitudinal edges of the associated masking tape portion. That is, during application of the composite masking tape the masking tape portion is securely applied along the associated wall or surface that is to be masked. This results in a smooth transition between the masked and unmasked areas along which the treatment can be applied. If, however, during removal of the alignment tape portion, the longitudinally extending edges of the masking layer, such as edges 310 and 312 of masking tape portion 302, for example, are lifted or peeled away from the associated wall or surface, an undesirable transition between the masked and unmasked areas could result. By providing adhesive relief areas, such as areas 332 and 334, for example, this lifting or peel away of the masking tape portion can be minimized or avoided.
Yet another embodiment of a composite masking tape 400 is shown in
Composite masking tape 400 differs from composite masking tape 300 discussed above with regard to
One advantage of using a deadening compound to form the adhesive relief areas is that the compound can be applied at or during assembly of the masking and alignment tape portions. This helps minimize any potential indexing, registration or alignment issues that may be associated with trying to establish and maintain a relationship between tape portions that include earlier applied coatings or layers.
A further embodiment of a composite masking tape 500 is shown in
It will be appreciated that the masking and alignment tape portions are arranged in a manner that is substantially similar to that shown in and described with regard to the composite masking tapes shown and discussed herein with regard to
Additionally, composite masking tape 500 includes a first adhesive layer 526 disposed along bottom surface 506 of masking tape portion 502, and a second adhesive layer 528 disposed along bottom surface 514 of alignment tape portion 504. In one exemplary embodiment, the first adhesive layer has a greater strength or tenacity than the second adhesive layer, as suggested by the different line weights shown in
Furthermore, to prevent first adhesive layer 526 from inadvertently becoming attached to other surfaces, composite masking tape 500 also includes an optional releasable liner 532 disposed longitudinally along masking tape portion 502. Liner 532 has a bottom surface or side 534 and a top surface or side 536 extending between opposing edges 538 and 540. Liner 532 is positioned along masking tape portion 502, such that top surface 536 is adjacent bottom surface 506, and is secured along adhesive layer 526. In the exemplary embodiment shown in
The release liner acts to prevent the first adhesive layer from being inadvertently secured onto a surface prior to use. For example, masking products are commonly packaged in roll form. As such, the first adhesive layer is normally adjacent the underlying wrap of material on the roll. By including the releasable liner, the first adhesive layer does not directly contact the underlying wrap of material and, as such, does not inadvertently adhere to the exposed surface of the wrap. An alternate construction is shown in
In the foregoing exemplary embodiments, the masking and alignment tape portions are preferably secured to one another using a second adhesive layer, such as one of layers 128, 228, 328, 428 and 528, for example, having an at least slightly lesser strength or tenacity than that associated with a first adhesive layer, such as one of layers 126, 226, 326, 426 and 526, for example. This can be achieved in any suitable manner, such as by using a first adhesive compound to form the first layer that has greater adhesive properties than a second, different adhesive compound that is used for the second layer. As another example, the adhesive compound of the first adhesive layer can have substantially the same adhesive properties as that of the second adhesive layer, and a suitable coating or pre-coated material, such as one or more of release coatings 130, 132, 530 and/or 542, for example, can be used in association with the adhesive layers to facilitate the release of the adhesive bond, as will be discussed in detail hereinafter. As a further example, the same or similar adhesive compounds could be used to form the first and second adhesive layers with the first layer being formed form a full, uniform coating of adhesive compound and the second layer being formed from a patterned, zone applied or otherwise discontinuous coating of adhesive compound having areas of substantially uncoated material. It will be appreciated that adhesive compounds, such as those suitable for use in forming the adhesive layers described herein, compounds suitable for forming release coatings, such as coatings 130, 132, 530 and/or 542 for example, and deadening compounds, such as compound 430, for example, are well known and commonly used, and that one of skill in the art will be capable of determining the appropriate adhesive compounds, coatings and materials for use depending upon the specifics of each application. Furthermore, it will be appreciated by the skilled artisan that any suitable combination of adhesive strength, release coatings and/or deadening compounds can be used without departing from the principles of the present novel concept.
The foregoing and other exemplary embodiments of a composite masking tape can be formed from any suitable compounds, such as release coatings, deadening compounds and adhesives; materials, such as paper (coated or uncoated), cellulose or fiber (natural or synthetic, coated or uncoated) and/or polymeric materials; and/or any combination of the foregoing and/or other compounds and materials. The adhesive layers discussed can be formed from any suitable adhesive compound or compounds, such as acrylic-based adhesives or natural or synthetic rubber-containing adhesives, for example. Deadening compounds as discussed herein can be formed from any suitable compounds or combination of materials in any form (e.g., liquid, gel, powder), and can be operative to deaden the tack of the adhesive in any suitable manner, such as by covering the adhesive or by chemically changing the adhesive, for example. Exemplary materials for use as a deadening compound include, without limitation, water-based inks and solvent-based inks, for example. The release coating can be formed from any suitable compound or compounds, such as silicone-containing compounds, vinylacetate-containing compounds, acrylic-containing compounds, or any combination thereof, for example.
As one example of a suitable construction, the masking tape portion and the alignment tape portion could each be formed from a suitable paper material, such as wood-pulp paper or rice paper, for example. As another example, both the masking tape portion and the alignment tape portion could be formed from the same or different polymeric materials, such as a vinyl-containing material or a polyolefin-containing material, for example. As a further example, the masking tape portion can be formed from a polymeric material, such as a vinyl-containing material or a polyolefin-containing material, for example, and the alignment tape portion can be formed from a paper material, such as wood-pulp paper coated with a silicone-containing compound, for example. Additionally, an optional release liner can be included opposite the alignment tape portion and the release liner can be formed from a paper material, such as wood-pulp paper coated with a silicone-containing compound, for example, or from a polymeric material, such as a polyolefin-containing material or a vinyl-containing material, for example. As such, it is to be understood that any suitable materials or combination of materials can be used without departing from the principles of the present novel concept. It will also be appreciated that the tape portions shown in the drawings are not to scale and are shown with an increased thickness dimension for clarity and ease of illustration.
In
As shown in
A method 600 of using a composite masking tape, such as tapes 100, 200, 300, 400 and/or 500, for example, is shown in
Depending upon the specifics of the application and wall structure, as well as the desired result, the user may choose to apply a second length of composite masking tape. As such, an inquiry is made in decision step 612 as to whether or not a second length of tape will be used. If a NO decision is made, the user proceeds to remove the alignment layer or tape portion from the first length of tape, as indicated in step 614. The associated feature can then be treated, as indicated by step 616, and the masking layer or tape portion can then be removed at a suitable interval, as indicated at step 618.
Should the user determine that a second length of composite masking tape will be used, then a YES decision is reached at decision step 612. As such, a second length of composite masking tape, such as tapes 100, 200300, 400 and/or 500, for example, is provided in step 620. Regardless of which composite tape construction was used for the first length of masking tape, any of the available constructions can be used in step 620. Accordingly, a determination is again made in decision step 622 as to whether or not a product having two different overhang dimensions is available and will be used. If a YES decision is reached by the user, then a step 624 of selecting the desired overhang dimension and a step 626 of suitably orienting the desired overhang along the feature are completed.
After step 626 or, alternately, if a NO decision is reached at decision step 622 indicating that a tape product having a single overhang dimension is to be used, a determination is made in decision step 628 as to whether the alignment tape portion of the first length of composite tape will be used to align the second length of composite tape along the feature. If a NO decision is made, then the alignment tape portion is removed, as indicated in step 630. After step 630 or, alternately, if a YES determination is made at decision step 628, the second length of composite tape is applied along the associated wall as indicated at step 632, using the appropriate surface or structure for alignment. Thereafter, any remaining alignment layers or tape portions are removed in step 614. The treatment is then applied to or along the associated features in step 616 and the masking portions can then be removed after a suitable interval, as indicated by step 618.
Step 602 discussed above can be accomplished in any suitable manner and can optionally include additional steps, as indicated in
Associated first and second walls WL1 and WL2 as well as associated joint JNT are shown and described herein, and specific reference is made to these features.
