BACKGROUND

Technical Field

[0001] The presently disclosed subject matter relates to a tillable instrument that dispenses paint through a tip onto a surface in order to repair blemishes, and more particularly, to an instrument for dispensing paint that includes an advancement mechanism for supplying paint at a rate that can be controlled by the user, and a related method and kit for using same.

Related Art

[0002] Conventional approaches to applying paint typically involve the use of an instrument, such as a paint brush or paint roller, and a container where the paint is stored. This approach can be efficient for larger painting projects where there is an expectation that all of the paint will be used. However, touch-up and finishing projects typically require a smaller amount of paint and are often done sometime after the original paint job was completed. In these cases, a user will typically need to find the original paint container and use a painting instrument to make the desired touch-ups. This approach often results in spilled paint as the user moves the paint container to each location requiring a touch-up. In many cases, more paint is spilled or lost than is actually needed for the touch-up project.

[0003] In view of the foregoing drawbacks, it would be desirable to have a system and methodology that provides a user with a portable and easily maneuverable paint applicator that minimizes the risk of spills and lost paint.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0018] The presently disclosed subject matter will be described in detail hereinafter with reference to exemplary embodiments shown in the accompanying drawings.

[0019] Fig. 1 is an exploded view of an embodiment of a paint applicator 100 made in accordance with principles of the disclosed subject matter. Fig. 1 shows that the paint applicator

100 includes a main body 110 which is cylindrical and/or pen-shaped. An applicator portion 120 for applying paint is disposed at a first or forward end of the main body 110. A cover 150 may be provided to cover the applicator 120 before and after the use of the paint applicator 100. An end cap 130 is fitted onto a second or aft end of the main body 130. As will be described in greater detail below, the end cap 130 may be communicatively coupled to an advancement mechanism 105.

[0020] According to the embodiment of Fig. 1, the main body 110 is cylindrical and pen- shaped and includes an interior volume 115 capable of receiving and holding paint. The applicator portion 120 is in fluid communication with the interior volume 115 of the main body

110 so that the applicator portion 120 can receive paint stored in the interior volume 115 to be dispensed onto a surface or substrate. In another embodiment, the main body 110 is capable of receiving a pre-filled paint cartridge which can be fitted into the interior volume 115 of the main body 110. For example, the paint can be advanced through the interior volume 115 by the advancement mechanism 105 which is described in greater detail below.

[0021] The main body 110 can be formed from a clear plastic so that the user can see the color and level of the paint. In one embodiment, small ball bearings 160 can be optionally added into the interior volume 115 to assist with mixing of the paint. An interior surface of the main body can also be equipped with ridges 155 which are formed in a circular pattern on the interior surface. As will be discussed in greater detail below, the ridges 155 assist with maintaining the position of the advancement mechanism 105 within the interior volume 115 of the main body

110.

[0022] As described above, Fig. 1 also shows the applicator portion 120 which is fitted onto a first end of the main body 110. In some embodiments, the interior volume 115 of the main body

110 can be filled with paint when the applicator portion 120 is disconnected from the main body

110. Then, the applicator portion 120 can be fitted onto the main body 110 through a variety of mechanisms. For example, it can be snap fitted onto the main body 110 or it can be screwed onto the main body 110 when the applicator portion 120 and the main body 110 are each fitted with one of threads or notches for receiving the threads. The applicator portion 120 is capable of receiving paint delivered from the interior volume 115 of the main body 110. The applicator portion 120 can then be used to apply paint onto a surface or substrate. The applicator portion

120 can also include a tip 125 which absorbs paint delivered through the interior volume 115 of the main body 110 and which is used to apply paint to a surface. An opening 195 can be formed at an end of the main body 110 for receiving paint and can be closed by attachment of the tip

125. The tip 125 can include a variety of different mechanisms for applying paint. For example, in Fig. 1, the tip 125 is shown as a paint brush. However, the disclosed subject matter contemplates that the tip can be any type of mechanism suitable for applying paint, such as a sponge, wick, paper product, etc.

[0023] Fig. 1 also shows the end cap 130 which is disposed at the far end of the main body 110. In some embodiments, the end cap 130 is fixed to the main body 110 so that it cannot be removed. In other embodiments, the end cap 130 can be removed in order to expose the interior volume 115 of the main body 110. In these embodiments, when the end cap 130 is removed, the interior volume 115 can be filled with a paint selected by the user. Alternately, when the end cap

130 is removed, a pre-filled paint cartridge holding paint can be inserted into the interior volume

115 of the main body 110. In this embodiment, once the interior volume 115 of the main body

110 is filled with paint, the end cap 130 can be placed back onto the end of the main body 110 so that the interior volume 115 is sealed. [0024] As will be described in greater detail below, the end cap 130 can also be used to drive the advancement mechanism 105 which forces the paint toward the applicator portion 120 to ensure that the applicator is wetted with enough paint so that it can be smoothly applied to a surface. Thus, rotation of the end cap 130 engages the advancement mechanism 105 in such a manner that the rotational force applied to the end cap 130 is translated to a linear force applied to a piston which pushes the paint toward the applicator portion 120.

[0025] Fig. 1 also shows the advancement mechanism 105 which includes an advancement head 165, and an advancement arm 170. The advancement mechanism also includes a base 175, a stem 180 and a piston head or plunger 185. The advancement head 165 of the advancement mechanism 105 can be fitted into a tip end of the end cap 130, so that rotation of the end cap 130 causes rotation of the advancement head 165 and the advancement arm 170. The piston head

185 faces and contacts the paint. An outer edge or rim of the piston 185 makes contact with the inner surface of the interior volume 115 of the main body 110 when the advancement mechanism

105 is placed into the interior volume 115. The piston 185 is advanced or retracted by the interaction between the advancement arm 170 and the stem 180 which each have mating threads. The base 175 also includes notches 190 which are formed along an outer edge of the base 175.

The notches 190 can mate with the ridges 155 formed on the interior surface of the main body

110 so that the advancement mechanism is fixed into the interior volume 115. As shown in Fig.

1, the advancement arm 170 extends from a bottom surface of the advancement head 165. The advancement arm 170 has interior threads (not shown in Fig. 1) that can engage the threads formed on the stem 180. Thus, the advancement head 165 can be fitted into the end cap 130 so that a rotational force applied to the end cap 130 also causes rotation of the advancement head

165. This rotational force also causes the advancement arm 170 to rotate so that the interior threads of the advancement arm 170 engage the threads of the stem 180 so that the piston head

185 moves in a linear direction away from the end cap 130. In this manner, the piston 185 is advanced through the interior volume 115 toward the tip 125 so that paint that occupies the interior volume 115 is forced onto the tip 125. Thus, in use, a user can rotate the end cap 130 to apply more paint to the tip 125 as it dries or needs replenishment. In this manner, a user can apply paint without the risk of spilling or wasting paint. [0026] The advancement mechanism 105 is configured so that the piston 185 can be retracted and the interior volume 115 can be cleaned and refilled allowing for multiple uses. In an alternate embodiment discussed below with reference to Fig. 4, the piston can only be moved in a direction towards the tip and cannot be retracted. In this embodiment, the paint applicator is a single use/disposable device which cannot be reused. Thus, once the user has used all of the paint contained in the interior volume, the paint applicator can then be disposed of.

[0027] Fig. 2 shows a perspective view of the applicator 100 of Figure 1. Figure 2 shows the advancement head 165 and the advancement arm 170 in communication with the base 175. As discussed above, both the advancement head 165 and the advancement arm 170 rotate when the end cap 130 (shown on Fig. 1) is rotated. Fig. 2 also shows that a base 175 is provided between the stem 180 and the plunger 185. The base 175 has notches 190 formed in a circular pattern around its outer periphery. The notches 190 mate with the ridges 155 formed on the interior surface of the interior volume 115 so that the base does not rotate when the advancement head

165 and advancement arm 170 are rotated. The base also includes a keyhole structure (not shown) through which the stem 180 is positioned so that it mates with interior threads 140 formed in the inner surface of the advancement arm 170 (see Fig 3). In this manner, rotation of the advancement head 165 causes rotation of the advancement arm 170 which causes the threads

140 to engage threads 310 of the stem to produce linear movement of the stem 180. In the embodiment of Figs. 1-3, the stem 180 and plunger 185 can be extended or retracted depending upon the rotational direction of the advancement head 165 and the advancement arm 170. Fig. 2 also shows an outer edge 210 of the piston head 185 that contacts the inner surface of the main body 110 to ensure that all or most of the paint loaded into the inner volume 115 is advanced.

[0028] Fig. 3 shows a perspective view of an applicator 100 with some minor modifications.

In Fig. 3, the stem 180 has a substantially rectangular cross-sectional shape with rounded edges so that threads 310 are only formed along the rounded edges and there are two opposed flat surfaces between the screw threads. These two flat surfaces are configured to act in coordination with a mating rectangular keyway located on the interior surface on the central axis of the base

175. It is noted that the advancement arm 170 is rotatable with respect to the base 175 (and therefore with respect to stem 180 and main body 110). The mating keyway surface of the base

175 prevents the stem 180 from rotating with respect to the base 175 and therefore also prevents rotation with respect main cylinder body 115. Thus, rotary movement of the end cap 130 is reliably transferred to linear movement of the piston 185 and stem 180.

[0029] The paint applicator 100 according to the disclosed embodiments provides a fillable device allowing users to fix paint blemishes without requiring the purchase of a large volume of paint. Instead, paint vendors can sell the paint applicators prefilled with a color requested by a consumer. The consumer can then purchase paint applicators 100 prefilled with the type of paints desired by the consumer and use them when needed. The paint applicator 100 can be light weight and maneuverable so that a user does not require any specialized skill in order to dispense paint for touch-up applications. In particular, the paint applicator 100 can be made primarily from transparent or clear polymers (except possibly for the tip 125 itself). The configuration of the applicator 100 also allows the user to accurately and precisely apply touch up paint to an area without over painting or without damaging the surface being painted. The paint applicator 100 will typically be filled with a water based, acrylic, latex and/or otherwise low VOC paint which has good flow properties and which will not easily dry and clog the mechanism. [0030] A user seeking to use the paint applicator 100 will first seek to load the interior volume

115 with paint. The paint applicator 100 may be configured with the applicator portion 120 already attached to the main body 110, or, alternately, with the applicator portion 120 disconnected from the main body 110. For packaging purposes, the applicator portion 120 can be nested to the interior volume 115 to reduce the size of the applicator 100. In this case, the user can remove the applicator portion 120 and attach it to the main body 110. In some embodiments, the applicator portion 120 can be snap fitted onto the end of the main body 110.

In other embodiments, the applicator portion 120 and the end of the main body 110 can be equipped with threads that allow the applicator portion 120 to be screwed into the main body

110. It is also contemplated that multiple applicator portions 120 can be provided with the device so that a user can quickly change out a dry applicator and/or can quickly change color of paint being used by the device. In one embodiment, the user can fill the interior volume 115 with paint when the applicator portion 120 is removed from the main body 110. In order to minimize spills, the user can remove paint from a paint container using a syringe or other paint transfer structure and then deposit the paint from the syringe into the interior volume of the applicator 100. In another embodiment, the paint can be deposited from the other end of the applicator 100 by removing the end cap 130.

[0031] In another embodiment, a paint cartridge can be loaded into the interior volume 115 of the paint applicator. Pre-loaded paint cartridges have the added advantage that the user does not have to handle paint. The paint cartridge can be in many various forms, including a sealed plastic bag that is punctured after insertion into the interior volume 115. Alternatively, plastic cylinders pre-filled with paint could be sold that fit within the interior volume 115 and only disperse paint when a force is applied to one or both ends of the plastic cylinder.

[0032] Once the interior volume 115 is loaded with paint, the user can rotate the end cap 130 into order to wet the tip 125. Rotating the end cap 130 cause the end cap 130 to engage and rotate the advancement head 165. Rotation of the advancement head 165 also causes rotation of the advancement arm 170 which in turn causes the linear advancement of the stem 180 in a direction toward the tip 125. As the stem 180 advances, the piston 185 also advances pushing the paint in the direction of the tip 125. The user can continue to turn the end cap 130 until the tip 125 has enough paint for the desired use. When the user determines that the tip requires more paint, he or she can advance the paint by turning the end cap 130. As described above, the base

175 generally holds the advancement mechanism 105 in place through the engagement notches 190 with the ridges 155.

[0033] Once the user has completed the project, the user can either dispose of the applicator 100 or can retract the piston 185 by turning the end cap 130 in a direction opposite to the direction turned for advancing the piston. The user can then clean out the inner volume 115 and reuse the applicator as needed.

[0034] Fig. 4 is an exploded view of another embodiment of a paint applicator 400 in which the advancement mechanism cannot be retracted once the piston is advanced. Thus, the embodiment of Fig. 4 can be considered a single use device. Fig. 4 shows a paint applicator 400 that includes a main body 410 which is cylindrical and/or pen-shaped. An applicator portion 420 for applying paint is disposed at a first or forward end of the main body 410. A cover 450 may be provided to cover the applicator portion 420 before and after use of the paint applicator 400. An end cap 430 is fitted onto a second or aft end of the main body 410. The end cap 430 includes a plurality of engagement teeth 435 which engage an advancement mechanism 405 as described in greater detail below.

[0035] According to the embodiment of Fig. 4, the main body 410 is cylindrical and pen- shaped and includes an interior volume 415 capable of receiving and holding paint. The applicator portion 420 is in fluid communication with the interior volume 415 of the main body

410 so that the applicator portion 420 receives paint to be dispensed onto a surface. In another embodiment, the main body 410 is capable of receiving a pre-filled paint cartridge which can be fitted into the interior volume 415 of the main body 410. In either of these embodiments, the paint can be advanced through the interior volume 415 by an advancement mechanism 405 which is described in greater detail below.

[0036] As with the embodiment of Fig. 1, the main body 410 can be formed from a clear plastic so that the user can see the color and level of the paint. In one embodiment, small ball bearings (not shown in Fig. 4) can be optionally added into the interior volume 415 to assist with mixing of the paint. An interior surface of the main body 410 can also be equipped with ridges

455 which are formed in a circular pattern on the interior surface. As will be discussed in greater detail below, the ridges assist with maintaining the position of the advancement mechanism 405 within the interior volume of the main body 410.

[0037] In one embodiment, the applicator portion 420 can be removably fitted onto a first end of the main body 410. In these embodiments, the interior volume 415 of the main body 410 can be filled with paint when the applicator portion 420 is disconnected from the main body 410.

Then, the applicator portion 420 can be fitted onto the main body 410 through a variety of mechanisms. For example, it can be snap fitted onto the main body 410 or it can be screwed onto the main body 410 if the applicator portion 420 and the main body are each fitted with one of threads or notches for receiving the threads. The applicator portion 420 is capable of receiving paint delivered from the interior volume 415 of the main body 410. The applicator portion 420 can then be used to apply paint onto a surface or substrate. The applicator portion

420 can also include a tip 425 which absorbs paint delivered through the interior volume 415 of the main body 410 and is used to apply paint to a surface. An opening 495 can be formed at an end of the main body 410 for receiving paint and can be closed by attachment of the tip 425.

The tip 425 can include a variety of different mechanisms for applying paint. For example, in Fig. 4, the tip 425 is shown as a paint brush. However, the disclosed embodiments contemplate that the tip can be any type of mechanism suitable for applying paint, such as a sponge, wick, paper product, etc.

[0038] Fig. 4 also shows the end cap 430 which is disposed at the far end of the main body 410. In some embodiments, the end cap 430 is fixed to the main body 410 so that it cannot be removed. In other embodiments, the end cap 430 can be removed in order to expose the interior volume 415 of the main body 410. In these embodiments, when the end cap 430 is removed, the interior volume 415 can be filled with a paint selected by the user. Alternately, when the end cap

430 is removed, a pre-filled paint cartridge holding paint can be inserted into the interior volume

415 of the main body 410. For example, once the interior volume 415 of the main body 410 is filled with paint, the end cap 430 can be placed back onto the end of the main body 410 so that the interior volume 415 is sealed.

[0039] The end cap 430 can also be used to drive the advancement mechanism 405 which forces the paint toward the applicator portion 420 to ensure that the tip 425 is wetted with enough paint so that it can be applied to a surface. The end cap 430 can be rotated so as to the advancement mechanism 405 in such a manner that the rotational force applied to the end cap 430 is translated to a linear force applied to a piston which pushes the paint toward the applicator portion 420. The end cap can be securely fitted onto the end of the main body 410 so as to engage a portion of the advancement mechanism 405.

[0040] Fig. 4 also shows the advancement mechanism 405 which includes a ratchet head 460 and a ratchet arm 465. The advancement mechanism 405 also includes a base 470, a stem 480 and a piston head or plunger 485. The ratchet head 460 of the advancement mechanism 405 can be fitted into the end cap 430, so that rotation of the end cap 430 cause rotation of the ratchet head 460 and the ratchet arm 465. The piston head 485 faces and contacts the paint. An outer edge or rim of the piston 485 makes contact with the inner surface of the interior volume 415 of the main body 410 when the advancement mechanism 405 is placed into the interior volume 415.

The piston 485 is advanced or retracted by action of the ratchet arm 465 which contacts the stem

480 and which each have mating threads. The base 470 includes notches 490 which are formed along an outer edge of the base 470. The notches 190 can mate with the ridges 455 formed on the interior surface of the main body 410 so that the advancement mechanism 405 is fixed into the interior volume 415. As shown in Fig. 4, the ratchet arm 465 extends from a bottom surface of the ratchet head 460. The ratchet arm 465 has interior threads (not shown in Fig. 4 but similar to threads 140 of Fig. 2) that can engage the threads formed on the stem 480. Thus, the ratchet head 460 can be fitted into the end cap 430 so that a rotational force applied to the end cap 430 also causes rotation of the ratchet head 460. This rotational force also causes the ratchet arm 465 to rotate so that the interior threads of the ratchet arm 465 engage the threads of the stem 480 so that both the stem 480 and the piston head 485 move in a linear direction away from the end cap

430. In this manner, the piston 485 is advanced through the interior volume 415 toward the tip

425 so that paint that occupies the interior volume 415 is forced onto the tip 425. Thus, in use, a user can rotate the end cap 430 to apply more paint to the tip 425 as it dries or needs

replenishment. In this manner, a user can apply paint without the risk of spilling or wasting paint.

[0041] The advancement mechanism 405 is configured so that the piston 485 cannot be retracted and can only move in a direction of the tip 425. Thus, in this embodiment, the paint applicator 400 is a single use/disposable device which cannot be reused. Thus, once the user has used all of the paint contained in the interior volume 415, the paint applicator 400 can then be disposed of. As shown in Fig. 4, the end cap 430 includes ratchet teeth 435 formed along the circumference of the lower end of the end cap 430. The base 470 also includes at least one ratchet arm 475 formed along a top surface of the base 470. The combination of the ratchet teeth

435 and ratchet arms 475 forms a system in which the end cap 430 and the ratchet arm 465 are allowed to rotate in a first direction (e.g., clockwise as shown in Fig. 4) and are prevented from rotating in an opposite direction. Thus, this structure provides for incremental advancement of the piston in only one direction, e.g., the direction of the tip 425. The ratchet teeth 435 can be in constant communication with the ratchet arms 475 by spring bias of the ratchet arms 475. When the end cap 430 is rotated, the ratchet teeth 435 pass by the ratchet arms 475 which then, in a step- wise fashion, limit advancement of the piston 485. The ratchet teeth 435 and ratchet arms

475 are also configured so that the end cap can only be turned in one direction, for advancement of the piston 485. The engagement teeth 435 and ratchet arms 475 are oriented in such a fashion that they will not allow reverse motion of the end cap 430. [0042] Fig. 5 shows a plan view of the advancement mechanism 405 and end cap 430 of Fig. 4.

Fig. 5 shows that the end cap 430 includes engagement teeth 435 formed along its lower surface.

Fig. 5 also shows that the ratchet head 460 and ratchet arm 465 are fitted into the end cap 430.

Fig. 5 further shows the base 470 that includes ratchet arms 475 and notches 490. A stem 480 includes a piston head 485 while the opposing end of the stem 480 extends through a key hole

(not shown) formed in the base 470 and into an opening formed in the ratchet arm 465. The opening of the ratchet arm 465 includes threads (like those shown in Fig. 2) that engage with the threads of the stem 480. Thus, rotation of the end cap 430 causes the stem 480 to extend or move in a linear direction. The ratchet teeth 435 and ratchet arms 475 form a system that allows to piston 485 to advance in an incremental or step-wise fashion. This prevents a user from discharging the paint too quickly and also prevents retraction of the piston 485 toward the direction of the end cap 430. As shown in Fig. 5, when the user rotates the end cap 430 in a clockwise manner, the ratchet teeth 435 ride along a top surface of the ratchet arms 475 allowing rotation in an incremental manner. The sloped orientation of the ratchet teeth 435 prevents rotation in a counterclockwise direction because the ratchet arms 475 block rotation of the ratchet teeth in a counterclockwise direction.

[0043] Fig. 6 shows the applicator 400 of Fig. 4 with the cover or cap 450 removed so that the applicator can be used.

[0044] Fig. 7 shows the applicator 400 of Fig. 4 with the cover or cap 450 fitted over the applicator portion 420 to prevent drying of the tip.

[0045] Fig. 8 shows a kit that includes an applicator 400 and a syringe 820 that can be used to load the applicator 400 with paint. A user seeking to use the paint applicator 400 will first seek to load the body of the applicator 400 with paint. As described in connection with Figs. 1-3, the paint applicator 400 may be configured with the applicator portion 420 already attached to its main body, or, alternately, with the applicator portion 420 disconnected from the main body. For packaging purposes, the applicator portion 420 can be nested to the interior volume of the applicator to reduce its size for packaging purposes. In this case, the user can remove the applicator portion 120 and fill the applicator body through an opening 495. Thus, the user can use a paint transfer structure, such as the syringe 820, to withdraw paint from a paint container 830. The user can then dispense the paint from the syringe 820 into the body of the applicator

400 via the opening 495. Once the paint has been dispensed into the body of the applicator, the applicator portion 420 can be snap fitted onto the end of the main body of the applicator. The paint transfer structure can also be in the form of a cartridge as described above, or a sample paint tube, or other paint containing structures. In other embodiments, the applicator portion 420 and the end of the main body of the applicator can be equipped with threads that allow the applicator portion 420 to be screwed into the main body of the applicator 400. It is also contemplated that multiple applicator portions 420 can be provided with the device so that a user can quickly change out a dry applicator and/or can quickly change color of paint being used by the device. Thus, use of the syringe can minimize spills.

[0046] In another embodiment, a paint cartridge can be loaded into the interior volume of the applicator 400. Pre-loaded paint cartridges have the added advantage that the user does not have to handle paint. The paint cartridge can be in many various forms, including a sealed plastic bag that is punctured after insertion into the interior volume 415. Alternatively, plastic cylinders pre- filled with paint could be sold that fit within the interior volume of the applicator and only disperse paint when a force is applied to one or both ends of the plastic cylinder.

[0047] Once the interior volume of the applicator is loaded with paint, the user can rotate the end cap 430 in order to wet the tip 425. Rotating the end cap 430 causes the end cap 430 to engage and rotate the ratchet head 460. Rotation of the ratchet head 460 also causes rotation of the ratchet arm 465 which in turn causes the advancement of the stem 480 in a direction toward the tip 425. As the stem 480 advances, the piston 485 also advances pushing the paint in the direction of the tip 425. The user can continue to turn the end cap 430 until the tip 425 has enough paint for the desired use. When the user determines that the tip requires more paint, he can advance the paint by turning the end cap 430. As described above, the base 470 generally holds the advancement mechanism 405 in place through the engagement of the notches

490 with the ridges 455. Also, as described above, the ratchet system formed by the ratchet teeth

435 and the ratchet arms 475 limit movement of the piston 485 in one direction and in a stepwise incremental fashion. This can prevent a user from discharging the paint too quickly. Once the user has completed the project, the user can dispose of the applicator 400. [0048] It should be understood that various modifications may be made to the various embodiments and modifications described above without departing from the spirit and scope of the disclosed subject matter. In particular, each of the structures shown in the various modifications and embodiments can be combined and/or exchanged with each other in accordance with various aspects and desired applications. In addition, the main cylindrical body is shown as having a shape that is circle in cross-section (when viewed along a longitudinal axis direction). However, different cross-sectional shapes for the main cylindrical body are contemplated as part of the disclosed subject matter, including polygonal, no n- symmetrical, and other shapes that may be beneficial for a particular application or marketing purpose.

Furthermore, if the entire length of the cylinder main body 115 has a complimentary polygonal or no n- symmetrical cross-sectional shape with respect to a shape of the piston, the keyway in the base 175 may not be necessary because the piston 185 and stem 180 would be prevented from rotation by the complimentary shape of the main cylindrical body 115.

[0049] It should be understood that the applicator could be made of a variety of materials, not limited to plastics and polymers, depending on the nature and reactivity of the paint or stain. Thus, the applicator could be formed from other materials, including but not limited to glass, ceramics, metals, etc.

[0050] The apparatus, kit and method can include a plurality of different or identical tips. For example, the apparatus or kit can include different sized brushes that can be selectively used depending on the surface area, surface type, and size of the application. In addition, different types of tips can be included with the apparatus, kit and method to allow for different applications. For example, a brush tip, a ball point tip, a sponge tip, and/or other tip can all be included with the applicator so that the user has many different options and styles of use of the applicator.

[0051] The method of using the apparatus or kit as disclosed above can include using the device in conjunction with stains, furniture stains or polishes in order to touch up furniture, statues, paintings or other artwork. The use of the disclosed apparatus and kit in such a method allows quick, easy, and clean touch ups that can easily be conducted by the homeowner, sales agents, interior decorators and others without requiring drop cloths, tapings, and other items typically required when painting or touching up items located within a furnished or otherwise finished room.

[0052] While there has been described what are at present considered to be exemplary embodiments of the present invention, it will be understood that various modifications may be made thereto, and it is intended that the appended claims cover all such modifications as fall within the true spirit and scope of the invention.
