The presently disclosed subject matter relates to a fillable 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.
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.
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.
The disclosed embodiments provide a fillable and adjustable paint applicator capable of interchangeably receiving a variety of different paints and a variety of paint applicators. According to one embodiment, the paint applicator includes a cylindrical, pen-shaped body capable of holding a paint, an applicator structure for dispensing the paint onto a surface and an advancement mechanism for forcing the paint into the applicator. The applicator structure can be one of a variety of applicators, such as paint brushes having a variety of shapes or a sponge or other mechanisms for applying paint. The applicator structure can be coupled to the pen-shaped body of the paint applicator through a variety of mechanisms. Thus, the disclosed embodiments provide for a removable and replaceable applicator allowing the user to apply paint through a variety of techniques.
The disclosed embodiments also provide for a cylindrical shaped pen-shaped body which is capable of receiving and storing paints. Paint can be loaded in an interior volume of the pen-shaped body by removing a cap which allows the paint to be poured or otherwise injected or placed into the pen-shaped body. In an alternate embodiment, the pen-shaped body is capable of receiving a pre-loaded paint cartridge which can be inserted and fitted into the pen-shaped body obviating the need to pour the paint directly into the pen-shaped body. The disclosed paint applicator also includes an end cap. The end cap covers the non-applicator end of the device and can be removed in order to add paint to the pen-shaped body. In one embodiment, the end cap also engages an advancement mechanism which pushes the paint toward the applicator. The advancement mechanism may include a piston mechanism which moves in a linear direction in response to the rotation of the end cap. Thus, the paint can be forced through the applicator toward a tip through the twisting motion of the end cap. The disclosed embodiments also include a cover which can be snapped on to the applicator in order to prevent drying of the applicator tip.
The disclosed embodiments also provide a paint applicator, including a cylindrical main body having a first end and a second end, the cylindrical main body defining an interior volume configured to receive a paint, an applicator structure disposed at the first end of the cylindrical main body, the applicator structure in fluid communication with the interior volume of the cylindrical main body, the applicator structure including a tip for applying the paint to a surface, an advancement mechanism for advancing the paint from the interior volume to the applicator structure, the advancement mechanism including an advancement arm and a piston with threaded piston rod, the advancement arm including threads for engaging the threaded piston rod and an end cap disposed adjacent the second end of the cylindrical main body, the end cap engaged to an end of the advancement arm.

The disclosed embodiments further provide a method for use of a paint applicator, including providing an applicator including a cylindrical main body having a first end and a second end, the cylindrical main body defining an interior volume configured to receive a paint, an applicator structure configured to be disposed at the first end of the cylindrical main body, the applicator structure including a tip for applying the paint to a surface, an advancement mechanism configured to advance the paint from the interior volume to the applicator structure, the advancement mechanism including a piston with piston rod, providing a paint transfer structure configured to transfer paint from a paint reservoir to the interior volume of the main body of the applicator, transferring paint from the paint reservoir to the paint transfer structure, transferring paint from the paint transfer structure to the interior volume of the main body of the applicator via the first end of the main body, placing the applicator structure in the first end of the main body such that the paint is in fluid communication with both the applicator structure and the interior volume of the main body and actuating the advancement mechanism such that the piston and piston rod move within the interior volume of the main body and cause paint from the interior volume to move to the applicator structure.
These and other characteristics of the presently disclosed subject matter will become clear from the following description with reference to the accompanying drawings, wherein:
The presently disclosed subject matter will be described in detail hereinafter with reference to exemplary embodiments shown in the accompanying drawings.
According to the embodiment of
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 110 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.
As described above,
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.
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
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.
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.
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.
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 of the notches 190 with the ridges 155.
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.
According to the embodiment of
As with the embodiment of
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
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 engage 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.
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
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.
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 or she 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.

However, different cross-sectional shapes for the main cylindrical body are contemplated as part of the disclosed subject matter, including polygonal, non-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 non-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.
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.
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.
