Masking tape tool guide
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to construction aids and more particularly pertains to masking tapes with tool guide which may be adapted for facilitating application of joint compound to wall joints and edges formed by drywall panels used to construct interior building walls. 
     2. Description of the Prior Art 
     The use of construction aids is known in the prior art. More specifically, construction aids heretofore devised and utilized for the purpose of applying joint compound to drywall joints during building construction are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     The present invention is directed to improving devices for facilitating application of joint compound to wall joints and edges formed by drywall panels used to construct interior building walls in a manner which is safe, secure, economical and aesthetically pleasing. 
     For example, U.S. Pat. No. 3,662,471 to Lynde discloses a measuring tape and chalk line holding tool, U.S. Pat. No. 4,942,670 to Brandt describes an adhesive template tape, and U.S. Pat. No. 4,949,462 to Spencer shows a drywall cutting guide. 
     The prior art also discloses a disposable layout tape as shown in U.S. Pat. No. 5,012,590 to Wagner et al., a drywall finishing tool adapter disclosed in U.S. Pat. No. 5,069,610 to Milburn, and a flexible reinforced polymeric material and a method of forming such a material of U.S. Pat. No. 5,098,768 to Holroyd et al. 
     While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a masking tape with tool guide for facilitating application of joint compound to wall joints and edges formed by drywall panels used to construct interior building walls. Furthermore, none of the prior art patents teach or suggest a way of quickly and accurately applying joint compound in a straight line without the need to follow a guide line. 
     In this respect, the masking tape with tool guide according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of facilitating application of joint compound to wall joints and edges formed by drywall panels used to construct interior building walls. 
     Therefore, it can be appreciated that there exists a continuing need for new masking tape with tool guide which can be used for facilitating application of joint compound to wall joints and edges formed by drywall panels used to construct interior building walls. In this regard, the present invention substantially fulfills this need. 
     As illustrated by the background art, efforts are continuously being made in an attempt to develop devices for applying joint compound to drywall joints during building construction. No prior effort, however, provides the benefits attendant with the present invention. Additionally, the prior patents and commercial techniques do not suggest the present inventive combination of component elements arranged and configured as disclosed and claimed herein. 
     The present invention achieves its intended purposes, objects, and advantages through a new, useful and unobvious combination of method steps and component elements, with the use of a minimum number of functioning parts, at a reasonable cost to manufacture, and by employing only readily available materials. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of construction aids now present in the prior art, the present invention provides a new construction aid construction wherein the same can be utilized for facilitating application of joint compound to wall joints and edges formed by drywall panels used to construct interior building walls. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new masking tape with tool guide apparatus and method which has all the advantages of the prior art construction aids and none of the disadvantages. 
     The invention is defined by the appended claims with the specific embodiment shown in the attached drawings. For the purpose of summarizing the invention, the invention may be incorporated into a new masking tape with tool guide for facilitating application of joint compound to wall joints and edges formed by drywall panels used to construct interior building walls. The masking tape with tool guide comprises an elongated strip of flexible solvent-resistant paper having pressure-sensitive adhesive disposed on one side thereof whereby the paper strip may be adhered to a drywall panel adjacent a joint to be finished with joint compound. The strip is divided centrally longitudinally into a first half and a second half. Release paper is disposed over the pressure-sensitive adhesive of the first half, the release paper being releasably adhered to the pressure-sensitive adhesive whereby preventing unwanted adhesion of the paper strip and protecting the adhesive from dirt prior to application to a drywall panel. A straightedge member is disposed over the pressure-sensitive adhesive of the second half, being fixedly adhered to the second half of the paper strip by the pressure-sensitive adhesive. The straightedge member comprises an elongated strip of flexible solvent-resistant plastic having an integral longitudinal lip formed along one edge thereof. The lip extends outwardly, over a longitudinal edge of the paper strip, normal the plane of the plastic strip and opposite the pressure-sensitive adhesive. The lip defines a ledge adjacent the drywall joint wherealong a drywall knife tool may be drawn during application of joint compound whereby aiding in the uniform application thereof.
