The subject application is related generally to tools and, more particularly, to tools for use in painting.
Painters typically use either a specially designed paint can opener or a regular (flathead) screwdriver to detach the lids of paint cans. Once a lid has been removed from a paint can, the paint contained therein must be thoroughly and rigorously mixed with a mixing stick. Thus, two completely independent tools are conventionally required to accomplish these tasks (lid removal and mixing). This increases the chances that either one of the tools could be forgotten, get lost, or break.
One aspect of the present invention is related to a tool for opening a container and for mixing a product contained in the container. The tool includes a mixing device which is shaped to mix the product contained in the container. A shank extends along a length from the mixing device to an end face. A channel is formed into the end face for receiving an edge of a lid of the container to allow the tool to be used to pry the lid off of the container.
According to another aspect of the present invention, the shank has a hexagonal shape as viewed in cross-section along most of its length.
According to yet another aspect of the present invention, the channel extends linearly from one corner of the hexagonal shape of the shank to an opposite corner.
According to still another aspect of the present invention, the end face of the shank is symmetrical about a plane which extends through the channel.
According to a further aspect of the present invention, the end face of the shank is symmetrical about a plane which extends perpendicularly across the channel.
According to yet a further aspect of the present invention, the mixing device is a mixing paddle.
According to still a further aspect of the present invention, the mixing paddle is generally kite-shaped.
According to another aspect of the present invention, the shank includes a groove which extends around the shank and which is spaced from the end face, and the channel extends approximately half a distance from the end face to the groove.
According to yet another aspect of the present invention, the mixing device and the shank are made of different materials.
According to still another aspect of the present invention, the mixing device is made of plastic, and the shank is made of metal.
Another aspect of the present invention is related to a method of opening and mixing the contents of a container. The method includes the step of preparing a mixing tool which includes a mixing device that is shaped to mix the product contained in the container, a shank which extends along a length form the mixing device to an end face, and a channel formed into the end face of the shank. The method proceeds with the step of inserting an edge of a lid of the container into the channel of the shank. The method continues with the step of prying the lid open using the mixing tool to expose the contents of the container. The method proceeds with the step of inserting a portion of the shank into the chuck of a drill or an impact driver. The method continues with the step of inserting the mixing device into the contents of the container. The method proceeds with the step of activating the drill or impact driver to mix the contents of the container with the mixing paddle.
According to another aspect of the present invention, the mixing device is a mixing paddle.
According to yet another aspect of the present invention, the mixing device is a mixing paddle.
According to still another aspect of the present invention, the mixing device is made of plastic.
According to a further aspect of the present invention, the shank is made of metal.
According yet a further aspect of the present invention, the shank has a hexagonal shape along most of its length.
According to still a further aspect of the present invention, the channel extends linearly from one corner of the hexagonal shape of the shank to an opposite corner of the hexagonal shape of the shank.
These and other features and advantages of the invention will become more readily appreciated when considered in connection with the following description of the presently preferred embodiments, appended claims and accompanying drawings, in which:
Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, an exemplary embodiment of an improved mixing tool 20 is generally shown in
In the exemplary embodiment, the mixing paddle 22 is generally kite-shaped with two pairs of sides 34a, 34b and wherein the lengths of the sides 34a, 34b in each pair are equal but the lengths of the sides 34a in one pair are different than the lengths of the sides 34b in the other pair. More specifically, the mixing paddle 22 includes a pair of short sides 34a that meet at the shank 24 and diverge away from one another in a direction away from the shank 24. The mixing paddle 22 also includes a pair of long sides 34b which extend from the ends of the short sides 34a and converge together at a rounded end corner. Rounded corners connect adjacent sides with one another. The mixing paddle 22 further includes a reinforcement 36 with an increased wall thickness adjacent the shank 24 for strengthening the mixing paddle 22 in this area where stresses from the mixing paddle 22 rotating are transferred to the shank 24 during a mixing operation. The mixing paddle 22 also includes a pair of flanges 38 which extend from the reinforcement 38 to the long sides 34b for improved mixing performance. Each of the flanges 38 has a progressively decreasing thickness in a direction towards the rounded end. The mixing paddle 22 is preferably made of plastic and is shaped through an injection molding operation.
The shank 24 extends along an axis A from the mixing paddle 22 to an end face 40. The shank 24 has two hexagonal portions 42a, 42b that are separated from one another by a groove 44 with a circular cross-sectional shape. That is, the shank 24 has a first hexagonal portion 42a which extends from the mixing paddle 22 to the groove 44 and a second hexagonal portion 42b which extends from the groove 44 to the end face 40. Each of the hexagonal portions 42a, 42b has a width, and the groove 44 has a diameter that is less than the width. The shank 24 is configured such that the end face can be inserted into the chuck 26 of an impact driver or a hand-held drill 28. The shank 24 is preferably made of metal, such as steel or an alloy steel, and may be shaped through any suitable operation including, for example, casting or forging. The shank 24 may have any suitable length from the mixing paddle 22 to the end face 40. For example, in various embodiments, the length of the shank 24 is three inches (3″), six inches (6″), nine inches (9″), and twelve inches (12″).
As shown in
In use, a user inserts the edge of the lid 52 of the paint can 30 (or other type of container) into the channel 46 formed at the end face 40 of the shank 24 and then uses leverage by forcing the shank 24 against an upper edge of the paint can 30 urging the length of the shank 24 and/or the mixing paddle 22 downwardly to pry the lid 52 open and, as shown in
The exemplary embodiment of the mixing tool 20 thus serves multiple related purposes that are often in a single, handy and very durable contraption which can be made at very low cost, as opposed to two separate devices. Further, the features which allow for these multiple purposes to be served are harmonious with one another in that neither in any way inhibits the performance of the other. That is, the channel 46, which allows the mixing tool 20 to remove the lid 52 from the paint can 30 (or other container), does not impair the performance of the mixing paddle 22, which allows the mixing tool to mix the paint 32 (or other contents), and likewise, the mixing paddle 22 does not impair the performance of the channel 46.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings and may be practiced otherwise than as specifically described while within the scope of the appended claims.
This application claims the benefit of U.S. Provisional Patent Application No. 62/808,040, filed Feb. 20, 2019, and titled “MIXING PADDLE TOOL SHANK”, the entire contents of which is herein incorporated by reference.
