The disclosure relates to the field of adhesive tape dispensers, and more particularly to an adhesive tape dispenser with a tape alignment mechanism,
In the field of painting, precision is a necessity for painters. Trim work in housing and other types of buildings needs to be covered during the process of painting walls, while the corners and edges of walls and ceilings need to be covered when more than one color is used. Crisp lines, colors riot running together, precision corner cutting for tape, and paints not being mixed are all part of the precision techniques of painting. Caulking is also a precision skill; areas next to those that are being caulked need to be covered so that they axe not accidentally caulked as well.
Painters often use adhesive tape to cover trims, corners, edges, and other parts that need protection from the paint and caulking process, Painters also use adhesive tapes as a form of stenciling when tasked with painting designs and patterns. However, application of long strips of tape with consistent alignment is difficult with existing tape dispensing devices and methods, particularly in corners such as where a floor meets the base of a wall. Existing tape dispensers further do not dispense tape with consistent alignment, and do not account for inconsistencies in manufacturing of rolls of tape, such as when the roll of tape is slightly conical due to mis-rolling or when the cardboard tape form bulges out slightly from the roll of tape. Taping along external (convex) corners is difficult, especially where such corners deviate from the perpendicular.
What is needed, then, is an adhesive tape dispensing device with a tape alignment mechanism that dispenses tape with consistent alignment, especially along eternal corners, and accounts for external corners that are not square.
Accordingly, the inventor has conceived and reduced to practice, an adhesive tape dispenser with tape alignment mechanism that dispenses tape with consistent alignment along external corners, even where such corners are not square. The following non-limiting summary of the invention is provided for clarity, and should be construed consistently with embodiments described in the detailed description below.

Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more communication means or intermediaries, logical or physical.
A description of an aspect with several components in communication with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible aspects and in order to more fully illustrate one or more aspects. Similarly, although process steps, method steps, algorithms or the like may be described in a sequential order, such processes, methods and algorithms may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the aspects, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, method, or algorithm is carried out or executed. Some steps may be omitted in some aspects or some occurrences, or some steps may be executed more than once in a given aspect or occurrence.
When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article.
The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other aspects need not include the device itself.
Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular aspects may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Process descriptions or blocks in figures should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of various aspects in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.
The term “adhesive tape” refers to any one of a variety of combinations of backing materials coated with an adhesive, typically in the burn of a ribbon or strip. Different backing materials and adhesives can be used depending on the intended use, and the width of the tape can vary, depending on the application.
The term “roll of tape” or “tape roll” means adhesive tape that has been wound in a continuous manner around a form, such as a cardboard tube, such that the tape forms a continuous spiral around the form.
The term “tape form” means a support structure around which adhesive tape may be wound to create a tape roll. A tape form is most often a section of cardboard tubing the same width as the tape, although the tape form may be made of other materials such as plastic metal, and is not necessarily circular in shape.
The term “tapered” means any object having a first width at a first end that narrows to a smaller second with a second end. Examples of a tapered shapes include, but are not limited to, cones, conical frustums, hyperboloids, paraboloids, and funnels.
The term “spring” as used herein means any spring-like device or material to which force may be applied in one direction, and which tends to resist that force by pushing back against it. In one aspect of an embodiment, a spring may be a wound metal wire, but in other embodiments, a spring may be of different forms and different materials. For example, a spring may be flexible, flat piece of metal (otherwise known as a “leaf” spring), or a tab molded into the body of the device.
It is important to note that tape is often mis-rolled, manufactured with inaccurate widths, etc.
In sonic embodiments, the springs may be fitted with bearings or rollers at the ends instead of nodules. In sonic embodiments, the tape alignment mechanism may push against the cardboard tube of the tape roll instead of pushing against the side or edge of the tape roll. In some embodiments, the alignment mechanism may guide the side or edge of a partially-dispensed portion of the tape instead of guiding the tape roll. In some embodiments, the alignment mechanism may comprise a force other than springs, such as gravity, to keep the tape aligned. In some embodiments, the tape alignment mechanism may comprised a combination of forces, such as springs and gravity, to keep the tape aligned.
The caulking spacer comprises a face plate 1221 made of a rigid material or materials which may be affixed to the open face (not visible in this perspective) of the body or shell 1211 via tabs, clips, or other fasteners 1222 which attach to the slots or other attachment points 1212. The caulking spacer 1220 may have an opening 1223 corresponding to the size and shape of the tape well 1213, which facilitates gripping of the tape dispenser 1210 with caulking spacer 1220 attached by allowing the user's lingers to be placed through the opening 1223. The thickness of the caulking spacer may vary, with the caulking spacer 1224 of this embodiment showing a thickness of ¼″. For dispensing of tape along external (i.e., convex) corners, a caulking spacer 1220 with guides or guide wings 1225 is used. Depending on the configuration, the guides 1225 may be molded onto or otherwise permanently attached to the caulking spacer 1220 or may be removable and re-attachable to the caulking spacer 1220. The guides 1225 may be offset from the caulking spacer 1220 such that the tape is dispensed not precisely at the edge of the external corner, but at a distance away from the edge that depends on the offset. The illustration here shows an embodiment without an offset.
For dispensing of tape along internal (i.e., concave) corners, the nose 1215 of the tape dispenser is pressed against a first surface while the caulking spacer is pressed against a second surface perpendicular to the first surface wherein the first and second surfaces meet at an internal (i.e., concave) corner (such as along the length of a window sill). When the user drags the tape dispenser 1210 along the first surface with the nose 1215 trailing, the tape is dispensed on the first surface at a distance of ¼″ from the second surface, Toward the end of dispensing, the user rotates the tape dispenser about the nose 1215 with the nose 1215 still pressed against the first surface, such the nose is now leading. The user pushes the nose into contact with a third surface (i.e., an internal corner now comprising the intersection of three perpendicular surfaces, such as the inside of one of the four corners of a window sill), and operates the cutting blade, which then cuts the tape at the precise length to lay the cut end of the tape exactly along the intersection between the second and third surfaces with the long edge of the tape having been applied along the intersection of the first and second surfaces at a distance of the thickness of the caulking spacer 1220. Different thicknesses of caulking spacer 1220 will cause the tape to be dispensed at different distances from the second, perpendicular surface.
For dispensing of tape along external (i.e., convex) corners, the nose 1215 of the tape dispenser is pressed against a first surface while one of the guides is pressed or held against a second surface (which may or may not be perpendicular to the first surface) wherein the first and second surfaces meet at an external (i.e., convex) corner (such as along the length of a window sill). When the user drags the tape dispenser 1210 along the first surface with the nose 1215 trailing, the tape is dispensed on the first surface at a distance of ¼″ from the second surface, Toward the end of dispensing, the user rotates the tape dispenser about the nose 1215 with the nose 1215 still pressed against the first surface, such the nose is now leading. The user pushes the nose into contact with a third surface (i.e., an internal corner now comprising the intersection of three perpendicular surfaces, such as the outside of one of the four corners of a window sill), and operates the cutting blade, which then cuts the tape at the precise length to lay the cut end of the tape exactly along the intersection between the second and third surfaces with the long edge of the tape having been applied along the intersection of the first and second surfaces at a distance of the thickness of the offset of the guides 1225 of the caulking spacer 1220. Different offsets of the guides will cause the tape to be dispensed at different distances from the second surface.
