Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present disclosure generally relates to a mixing apparatus and method of using the same, and more particularly to a mixing apparatus configured to mix contents of a container, e.g., aerosol cans, paint cans, or other containers.

Discussion of the Related Art

Conventional container and aerosol cans for holding material have a natural fault of letting the pigment (the color) settle in the bottom of the container, e.g., within the seams of the seal of the can. The settling of these pigments over any amount of time, increases additional effort by the user to mix the materials in the can, e.g., by physically shaking by hand for longer times other than recommended by the manufacture. The longer the container resides in an unused state requires more time and effort to mix the materials of the container. One related art paint mixer for the home is unsafe or hard to use, e.g., requiring tools that can be considered a specialty tool for the average home owner or hobbyist and they would never buy except to use that type of paint mixer.

There is a need for an inexpensive, safe, and improved apparatus for mixing contents of a container.

SUMMARY OF THE INVENTION

Accordingly, the invention is directed to a mixing apparatus, method of using and making the same that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention.

In one implementation, a mixing apparatus includes an apparatus that is configured to be used with a container having contents to permit mixing of the contents of the container. The apparatus includes a main body having a geometrical outer portion that defines a longitudinal axis, the geometrical body portion having an open end, a closed end, and a longitudinally extending bore or opening from the open end to the closed end. The opening or bore is configured to receive at least a portion of a container. A shaft is generally orthogonally positioned from a portion of the closed end. The shaft is configured to be received or inserted into a rotational device.

A mixing apparatus including a main body having a first end, a closed second end, and a longitudinally extending bore or lumen extending from the first end to the closed second end. The longitudinally extending bore or lumen is configured to receive at least a portion of a container. The container is not attached or directly attached to any portion of the main body. A rotational mechanism is arranged on a bottom portion of the main body configure to allow a rotation device with or without a secondary device, e.g., spindle or other attachment mechanism, to be releasably coupled to the rotational mechanism.

The main body may be constructed from a variety of different materials or combinations of materials including thermoplastic materials, metals, alloys, composites, wood, and the like. Some typical thermoplastic materials include polymers, polypropylene copolymer, prime polypropylene, acrylic, ABS, Nylon, PLA, polybenzimidazole, polycarbonate, polyethersulfone, polyoxymethylene, polyetheretherketone, polyetherimide, polyethylene, polyphenylene oxide, polyphenylene sulfide, polypropylene, polystyrene, polyvinyl chloride and polytetrafluoroethylene and combinations thereof and the like. Thermoplastics that are capable of injection molding, three-dimensional printed with a three-dimensional printer, or other molding, e.g., cavity molds, can also be used.

Optionally and/or alternatively, the thermoplastic materials have properties that allow them to be flexible without breaking in order to permit it to move or bend from a first orientation to a second orientation. In addition, in one implementation, the thermoplastic materials are configured, so the main body has shape memory in a preformed configuration or orientation. Some type of external force is required to move, bend, and/or twist at least a portion of the main body and the portion moves from a first position or orientation to a second position or orientation without breaker. Optionally, the thermoplastic material is strong enough to remain in a first position during operation, e.g., rotation. Further optionally and/or alternatively, a retaining strap or mechanism as described herein can be utilized to secure at least one more portion of the main body.

The main body and/or shaft may be of any color or combination of colors, e.g., any combination of red, green and blue. In one implementation, the main body is a solid fluorescent green color. The main body may also have different designs that create different impressions at different RPMs. The main body may also include embedded pictures, text, e.g., instructions in a portion of the main body interior or exterior.

The main body or housing is configured to hold at least a portion of a container and the container is arranged at least partially within a bore or lumen of the main body. The main body may be configured into any geometrical configuration with radial symmetry, e.g., circle, cylinder, oval, square, triangle, diamond, pentagon, hexagon, heptagon, octagon, nonagon, combinations of the same and the like. The main body also may be formed into one more section, e.g., claim shell type design. In addition, the main body may be formed with one or void spaces, e.g., a helical structure having void spaces between the helical windings. The main body may also have an open, partially opened, closed, partially closed, or closed first end and/or second end and combinations of the same. The main body may have one or more vents as described herein.

The inside diameter of the main body may be in a range from about 10 mm to about 300 mm or greater. In a preferred embodiment, inside diameter of the main body is about 50 mm to about 100 mm and is sized to accommodate different containers with varying outside diameter dimensions. The main body may also be configured with an offset by having a different inside diameter. In a preferred embodiment, the offset is created by a difference of inside diameters between a first end compared to the inside diameter at the second end. The first end may be bottommost portion of the main body and the second end may be uppermost portion of the main body. The offset can be in range from about 0.1 degrees to about 5 degrees or greater. In a preferred embodiment, the offset is about 1.5 to about 3 degrees. The offset can also be formed at any portion of the main body extending from the first end to the second end, e.g., the offset can be in a middle portion of the main body and extending to an uppermost portion. In one implementation, the main body includes a substantially cylindrical geometric configuration having a circumferential wall extending from the bottom end of the main body to a top end of the main body in a tapered configuration with about a 2 degree offset with an inside diameter at a bottom end of about 75 mm an inside diameter at a top end at about 80 mm. The main body may have thickness, e.g., wall thickness, in a range from about 0.0001 mm to 10 mm or greater. The thickness may vary throughout different locations of the main body.

In one implementation, the inside diameter of the main body of the apparatus may be constant along a longitudinal axis of the main body from a first end closed portion to a second end open portion. Optionally and/or alternatively, the inside diameter of the main body may linearly or non-linearly increase from the bottom end to the upper end. In one implementation, the inside diameter is configured to leave about 10 mm (5 mm on each side) of space when a container resides within a lumen of the main body, i.e., the inside diameter of the container is about 10 mm greater than an outside diameter of the container. This space dimension may also be greater or less than the 10 mm.

The main body may have a length in range from about 5 mm to about 250 mm or greater. The length of the main body may be configured to be greater than, less than or equal to the length of the container. Optionally and/or alternatively, the main body has a height to accept the full length of the aerosol can.

In one implementation, a shaft 110 is arranged at an orthogonal configuration relative to the flat base of a bottom end of the main body. The shaft is configured and sized to be inserted into a receiving portion of a rotational device. The receiving portion of the rotational device is a chuck or a specialized type of clamp configured to releasable hold at least a portion of the shaft. The chuck or clamp as known in the art is used to hold an object with radial symmetry, e.g., a cylinder.

The shaft may be constructed from a variety of different materials including thermoplastic materials, metal materials, alloy materials, wood materials, composite materials and combinations of the same. The shaft may be integral or constructed with the main body of a single solid unitary piece. The shaft may be the same or different materials relative to the main body.

The shaft may be centered with a central axis of the may body or offset. The shaft can be configured into a number of different geometrical configurations with radial symmetry, e.g., having a cross-sectional shape like a circle, triangle, square, pentagon, hexagon, heptagon, octagon, nonagon, combinations of the same and the like. The shaft may also have a constant diameter or dimension or a variable diameter or dimension from a first end to a second end. The change diameter of the shaft or dimension can be step change, linear change, and/or non-linear change.

The shaft can have a length from about 5 mm with a length of about 30 mm or greater.

Optionally and/or alternatively, the shaft 110 can be reinforced with materials, e.g., metals, composites, thermoplastics, alloys, combinations of the same and the like.

The shaft may also be reinforced with one or more supporting members configured to support the shaft and add weight to the apparatus. In one implementation, the supporting members are coequally spaced apart from each other in a radial configuration, however, they don't have to be coequally spaced. The number of supporting members may be increased or decreased. The supporting members are configured to add strength and rigidity to at least a portion of the shaft. In one implementation, the shaft is attached to the main body.

Optionally and/or alternatively, a rotational mechanism is used instead of a shaft coupled to the main body. When using the rotational mechanism, a removable shaft is attached to a rotation device at one end and the other end engages a recess or screw head in the rotation mechanism. In this implementation, the shaft is more of a spindle having any radial symmetry as described herein. The recess can include any screw head pattern as known in the art.

The container to be mixed may be any type of container with or without radial symmetry for holding any material and any physical state of matter of the material to be mixed. Some typical physical states include of materials include, e.g., liquid, solid, gas, plasma, semi-solid, liquid/solid, powder, and combinations of the same to be mixed. The liquid, liquid/solid, powder, and combinations of the same to be mixed may include any material to mixed. Some illustrative examples of materials to be mixed including, tattoo ink, model paints, chemicals, liquids, paints, epoxy, drink mixes, e.g., protein sport drink mixes, other powder and/or liquid mixes and the like. Essentially, the liquid, liquid/solid, powder, and combinations of the same to be mixed may be any material, liquid, solid or combination of the same desired to be mixed can be mixed with the mixing apparatus.

Some typical geometrical configurations of container with radial system include one or more of the following sided configurations, cylinder, oval, square, triangle, diamond, pentagon, hexagon, heptagon, octagon, nonagon, combinations of the same and the like.

In one implementation of the disclosure, the container is an aerosol container, for example, a single component system or more than one component system as described with reference to one or more of U.S. Pat. Nos. 7,204,392; 8,403,177; 8,528,837; and 9,493,292 and U.S. Patent Application Publication Nos.: 2001/0014700 and U.S. Patent Application Publication No. 2016/0002475, each of foregoing patents and patent applications are hereby fully incorporated by reference as if fully set forth herein.

In a preferred embodiment, the container relates to an aerosol can includes a body containing a propellant and an aerosol product, a valve whose actuation enables said aerosol product to be sprayed, and a spray head which serves to discharge the aerosol product to the environment when the valve is actuated, said spray head being provided with an axial borehole through which the aerosol product enters the spray head. The aerosol product to be sprayed is any aerosol product as known in the art, e.g., a varnish, a painting preparation agent or other coloring substance. The implementations of the disclosure apply to and is to be used for all types of aerosol cans as known in the art.

In one implementation of the disclosure, the aerosol container has a length in range of about 50 to about 200 mm or greater with a cap. In another implementation, the aerosol container has a length of about 150 mm in length and has a cap with a length of about 50 mm for a total length of about 200 mm. The aerosol container when arranged in a lumen of the main body has about 50 mm or more sticking out from the mixing apparatus. Leaving about one third or less (about 66 mm of the container extending outside the main body in this implementation). It is believed this creates enough support for the aerosol container to stay contained in the lumen of the main body without being physically attached to the apparatus while also using gravity and centrifugal force during operation. That is, there is no physical securing device to attach an aerosol can to the mixing unit.

In one implementation of the disclosure, the container is not attached, secured, or coupled to the main body of the mixing apparatus or another portion of the mixing apparatus. There is no mechanism for attaching, securing or directly attaching the container to the mixing apparatus or main body of the mixing apparatus. There is also no mechanism to provide a compression force to secure or attach any portion of the container to the main body. The container can rotate freely in the main body. Also, during operation, a user can stop the rotation of the container by holding a portion of the container and the main body continues to rotate. In one implementation, the container simply resides in at least a portion of the main body of the mixing apparatus such that more than quarter of the container's length extends past the main body. The diameter or dimension of the housing is greater than the diameter or dimension of the container. Typically, the container is held in place by gravity and at least a portion of the inner walls of the housing. The container may move independently from the housing.

In one implementation of the disclosure, the mixing apparatus and the container to be mixed are not coupled, directly coupled or attached together in any configuration. That is, the centrifugal force, i.e., an apparent force that acts outward on a body moving around a center, arising from the body's inertia, acts on the container in the housing by rotating the mixing apparatus. This allows a container to rotate in a lumen of the main body in a direction of the rotation of the housing. The container can also be moved independent when in the lumen of the main body from the main body. The mixing unit and/or housing has no attachment mechanism or means for the container to couple or attach releasably the container to the housing. The container can also rotate at a different rotational velocity as compared to the main body during operation for at least an amount of time, e.g., startup time or greater as described herein.

In one implementation of the disclosure, an inner surface of the main body may include an insert material, coating, geometric configuration, e.g., bumps, and other agitating mechanisms, e.g., one or more protrusions, e.g., blades, brushes, rubber blades, to assist with agitation of the contents of the container.

In one implementation of the disclosure, a lack of attachment mechanism is thought to be a safety feature. This safety feature allows a user to stop rotation of the container by applying a stopping force to the container independent of the housing of the mixing apparatus. The container residing within a portion of the housing can move independently or substantially independently from one another. In one implementation, a conventional drill is used as the rotation device and coupled to the shaft of the housing the drill can remain on in a rotation mode while a user holds the container with their hand to stop, slow or prevent rotation of the container while the housing is moving by the drill. In direct contrast, if the housing was directly coupled to the container this independent movement would not be possible. This independent motion allows the container rotational velocity to ramp more slowly upon starting rotation of the drill and slow more slowly upon deactivation of the drill. Moreover, a user has greater control of mixing compared to a unit that is coupled to container, e.g., a user can hold or partially hold the container throughout operation of the mixing unit to increase or decrease speed of the container by application of holding force as the container moves independent of the housing.

In one implementation of the disclosure, the apparatus can work with various sized containers having different dimensions in outside diameter or dimension, weight, and/or length. In addition, the main body permits one to rapidly mix multiple sized containers or the same sized containers as no attachment mechanism is required and instead as user can simply place a portion of the container in the main body, operate, and remove the container as no attachment mechanisms are required, and repeat. That is, there is no time lost by avoiding any time to couple and/or uncouple a housing of the mixing unit from the container.

Optionally and/or alternatively, the mixing unit can include one or more sensors configured to determine or be used as a timer, velocity, revolutions per minute (RPM), location, revolution counter, an electronic sensor unit configured to indicate when the liquid, liquid/solid, powder, and combinations of the same have been mixed or agitated to a predetermined condition, e.g., by indicating number of revolutions, time of revolutions and other data indicative of mixing. The predetermined condition can also be user specified.

Optionally and/or alternatively, the mixing apparatus may include one more commercial logos, trademarks writing or ornamental designs on any surface, embedded in the main body or shaft, affixed, e.g., sticker, decal and combinations of the same. The main body and/or shaft may also be constructed or include phosphorescence material, e.g., glow-in-dark, of any color or design.

In one implementation of the disclosure, one or more lights of one or more color are arranged on in a portion of the main body. For example, the one or more lights can be recessed within a portion of the main body, or completely covered within a portion of the main body. Optionally, the lights are configured to change color to indicate one or more of mixing complete, velocity, RPM, revolution counter, time, and the like. The lights can be conventional light emitting diodes (LEDs) as known in the art. The lights can be part of reinforcement ribs of the main body.

The rotational device can be any rotational device known in the art. The rotation device can be electronic, battery operated, operated with a direct connection to a power source, mechanically operated. The rotation device can also be integral with, e.g., non-detachable from the mixing apparatus. In one implementation, an integral mixing unit includes a rotational device that is integral with a portion of housing and cannot be attached or detached from a portion of the housing. The rotational device may include a drill, Dremel, mill, drill, electric drill, battery drill, mechanical drill, drill press, and other type devices as known in the art.

In one implementation of the disclosure, the rotation device is configured to rotate in a range from about 1 RPM to about 1500 RPM or greater. In one implementation, the RPM for mixing a typical aerosol can or paint container, is in a range from about 700 RPM to about 1300 RPM or greater.

In one implementation of the disclosure, a method of using a mixing apparatus for mixing contents of a container. The method includes providing any of the mixing apparatuses described herein. Providing a rotational device as described herein. Arranging the mixing apparatus into a bore or lumen of the main body of the mixing apparatus. Attaching the rotational device to a portion of the apparatus. Operating the rotation device to rotate the main body and container one or more RPMs for a predetermined time to achieve a desired mixing of one or more contents in the container.

In one implementation, the apparatus described herein can be made by an injection molding manufacturing process by injection of molten material into a mold with materials described herein, e.g., metals, glasses, elastomers, confections, thermoplastic and thermosetting polymers as known in the art. The apparatus can be fabricated as single unitary piece including the main body, shaft and any other implementations as described herein. Of course, other types of molding as known in the art may also be utilized, e.g., blow molding, powder metallurgy, compression molding, extrusion molding, laminating, rotational molding, thermoforming and combinations of the same and the like. The apparatus may also be constructed by three-dimensional printing. The apparatus may be constructed as not a single solidary unit.

Reference will now be made in detail to an embodiment of the present invention, example of which is illustrated in the accompanying drawings.

FIG. 1B illustrates a side perspective view of the mixing apparatus of FIG. 1A, according to an implementation of the present disclosure. FIG. 1C illustrates a bottom perspective view of the mixing apparatus of FIG. 1A, according to an implementation of the present disclosure.

Referring to FIGS. 1A-1C, a mixing apparatus 100 includes a main body or housing 102, a first end 104, a second end 106, a lumen or bore 108 extending from the first end 104 to the closed second end 106. The second end 106 of the main body 102 has a substantially flat base. A shaft 110 is arranged at an orthogonal configuration relative to the flat base of second end 106. The shaft 110 is configured and sized to be inserted into a receiving portion of a rotational device.

The receiving portion of the rotational device is a chuck or a specialized type of clamp configured to releasable hold at least a portion of the shaft 110. The chuck or clamp as known in the art is used to hold an object with radial symmetry, e.g., a cylinder.

The housing 102 is configured to hold at least a portion of container (not shown) and the container is arranged at least partially within a bore 108 of the main body 100. The main body 100 may be configured into any geometrical configuration with radial symmetry, e.g., cylinder, oval, square, triangle, diamond, pentagon, hexagon, heptagon, octagon, nonagon, combinations of the same and the like.

In this implementation, the main body 102 has a substantial cylindrical configuration having about a 1 degree or greater offset or angle from the second end 106 to the first end 104. The offset can be in range from about 0.1 degrees to about 5 degrees or greater. The offset is created by a difference of inside diameter between or at the second end 106 compared to the inside diameter at the first end 104. The inside diameter at the second end 106 is smaller than the inside diameter at the first end 104. In this configuration a container can be easily inserted into the lumen or bore 108 as the inside diameter at either the first end 104 or second end 106 is greater than any outside diameter of the container.

Optionally and/or alternatively, the inside diameter at the second end 106 may also be equal to or less than the inside diameter at the first end 104. When the inside diameter at the first end 104 is equal to the inside diameter at the second 106 there is no offset.

In this implementation, the inside diameter of the body 102 at the first end 104 is 84 mm and the inside diameter at the second end 106 is about 80 mm, thereby creating about a 2-degree offset and a cone type shaping of the cylinder from the second end 106 to the first end 104. In other implementations, the inside diameter at the first end 104 and second end 106 may be in a range from about 10 mm to about 150 mm or greater. The length 105 of the body 102 may be in a range from about 5 mm to about 250 mm or greater.

The main body 102 and shaft 110 may be constructed from a variety of different materials including thermoplastic materials, metal materials, alloy materials, wood materials, composite materials and combinations of the same. Housing 102 may be the same or different materials relative to the shaft 110. In this implementation the housing 102 and shaft 110 are constructed from the same thermoplastic material, as an integral unit with a single mold.

In this implementation the shaft 110 extends from the base of the body 102 and is substantially centered and extends orthogonally from the base. The shaft 110 has radial symmetry and is configured with a cylindrical geometry. In other implementations, the shaft 110 geometry may include any type of geometric shape with radial symmetry, e.g., triangle, square, pentagon, hexagon, heptagon, octagon, nonagon, combinations of the same and the like. The shaft 110 may also have a constant diameter or dimension or a variable diameter or dimension from a first end 112 to a second end 114. The change diameter of the shaft 110 or dimension can be step change, linear change, non-linear change. In this implementation the diameter is a constant dimension of about 10 mm with a length of about 30 mm. In another implementation, the diameter can be in a range from about 5 mm to about 15 mm or more. In a preferred embodiment, the diameter is about 8 mm to about 10 mm. The shaft may be any size and geometric configuration that is appropriate for common rotational devices, e.g., electric drill, mechanical drill, battery drill.

Optionally and/or alternatively, the shaft 110 can be reinforced with materials.

In this implementation, eight supporting members 116 are used to support the shaft 110. The supporting members 116 are coequally spaced apart from each other in a radial configuration. The number of supporting members 116 may be increased or decreased. The supporting members also add weight to a bottom portion of the housing 102. The supporting members 116 add strength and rigidity to the shaft. The shaft 110 may also be reinforced with various materials including, e.g., metals, composites, thermoplastics, alloys, combinations of the same and the like.

The shaft unit 210 includes a shaft unit having a radially symmetrical unit 209 and a coupling unit 207 configured to couple the radially symmetrical unit 209 to the main body 202 via the orifice 205. The radially symmetrical unit 209 includes a first end 212 and a second end 214. The second end includes a lumen to receive threaded portion of the coupling unit 207. The head 211 of the coupling unit 207 includes a slot drive configuration. However, any type of head screw type as known in the art may be utilized, e.g., cross, Philips, frearson, mortorq, hex and the like. In addition, any type of attachment mechanism may also be utilized to couple a main body to a shaft, e.g., rivet, bolt and nut, and others.

Referring to FIGS. 3A-3B, a mixing apparatus 300 includes a main body or housing 302, a first end 304, a second end 306, a lumen or bore 308 extending from the first end 304 to the second end 306. The second end 306 is closed and not open. The second end 306 of the main body 302 has a substantially flat base. A shaft 310 is arranged at an orthogonal configuration relative to the flat base of second end 306. The shaft 310 is configured and sized to be inserted into a receiving portion of a rotational device.

The mixing apparatus 300 also includes one or more vent holes 312 arranged in a circumferential orientation around a base portion of the main body 302. The vents 312 are configured to prevent or minimize a vacuum pressure from accruing when the container is removed or being inserted in the mixing apparatus 300. The vents 312 are sized to permit air to pass through the vents and prevent or minimize a vacuum pressure during insertions or removal of a container. In this implementation, the shaft 310 has an outer diameter of about 10 mm and a length of about 30 mm. Optionally and/or alternatively, vents 314 are arranged on a base portion. The number of vents 312 and 314 may be one to eight or more. The apparatus 300 further includes a 2 degree offset and reinforcement members 316 each of which is described herein.

FIG. 4A illustrates a side perspective view of a mixing apparatus and aerosol can in an unloaded configuration according to an implementation of the present disclosure. FIG. 4B illustrates a side perspective view of a mixing apparatus and aerosol can in a loaded configuration according to an implementation of the present disclosure. FIG. 4C illustrates a bottom perspective view of a mixing apparatus and rotational device in a connected configuration according to an implementation of the present disclosure.

Referring to FIGS. 4A-4C, a mixing apparatus 400 includes a main body or housing 402, a first end 404, a second end 406, a lumen or bore 408 extending from the first end 404 to the closed second end 406. The second end 406 of the main body 402 has a substantially flat base. A shaft 410 is arranged at an orthogonal configuration relative to the flat base of second end 406. The shaft 410 is configured and sized to be inserted into a receiving portion of a rotational device. The receiving portion of the rotational device 422 is a chuck or a specialized type of clamp 420 configured to releasable hold at least a portion of the shaft 410. The chuck or clamp 422 or other attachment mechanism as known in the art is used to hold an object with radial symmetry, e.g., a cylinder.

The housing 402 is configured to hold at least a portion of container (not shown) and the container is arranged at least partially within a bore 408 of the main body 402. The main body 402 may be configured into any geometrical configuration with radial symmetry and in this implementation is configured with a substantial cylindrical geometry. Optionally, the main body has an offset in a range from about 1 degree to about 5 degrees as described herein.

The main body 402 can have a length 405 in a range from about 10 mm to about 250 mm or more. In this implementation, the length 405 is about 140 mm. The main body 402 can have an inside diameter 403 in a range of about 1 mm to about 150 mm at the first end 404. In this implementation, the main body 402 has an inside diameter 403 of about 80 mm at the first end 404.

An aerosol container 407 is used as the container in this implementation. Typical aerosol containers have a length of about 100 mm to about 200 mm or more (with cap 415 where the cap is typically about 30 mm or greater) and an outside diameter in a range from about 5 mm to about 150 mm or greater. The outside diameter 411 is about 70 mm. The length 409 in this implementation is about 200 mm and outside diameter 411 of about 200 mm.

This leaves a total of about 10 mm of extra space between an outside diameter 411 of the can and inside diameter 403 of the main body 402 or about 5 mm on each side. Extra space of about 5 mm or greater allows a user to utilized different diameter containers readily. In one implementation, the total extra space between the inside diameter 403 of the main body 402 and the outside diameter 411 of the container 407 is in a range from about 1 mm to about 15 mm or greater.

Referring to FIG. 4B, the length 413 is about 65 mm, which is the length of the container sticking out from the lumen 408 of mixing apparatus 400 when the mixing container is fully seated in the lumen 408. In another implementation, the length 413 of the container 407 remaining outside the lumen 408 of the main body 402 is about one quarter or less the total length 409 of the container with a cap 415, it is believed leaving this amount length of the container inside and outside the lumen 408 provides adequate support of the main body sidewalls to support the container without physically coupling the container to the main body during operation. It is further believed the forces holding the container in place during operation include a gravitation force and centrifugal force. There is no physical securing device to attach the container to the mixing unit. Optionally, the length 405 of the main body 402 can be greater than the length 409 of the container, equal to or any size less than the container length 409. Optionally, the mixing apparatus can be utilized with a container having no cap or cap 415 removed from the container 407.

In this implementation, four supporting members 416 are used to support the shaft 410. The supporting members 416 are coequally spaced apart from each other in a radial configuration. The shaft 110 and main body are constructed from the same materials.

FIG. 5 illustrates a side perspective and partial cross-sectional view of a mixing apparatus according to an implementation of the present disclosure.

Referring to FIG. 5, the mixing apparatus 500 includes a main body or housing 502, a first end 504, a second end 506, a lumen or bore 508 extending from the first end 504 to the closed second end 506. The second end 506 of the main body 502 has a substantially flat base. A shaft 510 is arranged at an orthogonal configuration relative to the flat base of second end 506. The shaft 510 is configured and sized to be inserted into a receiving portion of a rotational device. The receiving portion of the rotational device 422 is a chuck or a specialized type of clamp configured to releasable hold at least a portion of the shaft 510. The chuck or clamp or other attachment mechanism as known in the art is used to hold an object with radial symmetry, e.g., a cylinder.

The housing 502 is configured to hold at least a portion of a container (not shown) and the container is arranged at least partially within a bore 508 of the main body 502. The main body 502 may be configured into any geometrical configuration with radial symmetry and in this implementation is configured with a substantial cylindrical geometry. Optionally, the main body has an offset in a range from about 1 degree to about 5 degrees as described herein.

In this implementation, the main body 502 further includes an insert material, coating, or combinations of the same 503. The material of insert material 503 may include one or more of, e.g., rubber, compressible material, non-compressible material, open celled foam material, closed cell foam material, memory foam material, sponge material, or combinations of the same or the like. The coating and/or insert material as an insert material 503 may include a frictional material configured to provide greater frictional forces to permit more rapid rotation of the container during start up and upon turning off the rotational apparatus. The insert material 503 can have a thickness of about 1 mm to about 5 mm or greater and length that is the same of the main body 502 or less than the main body 502. The insert material 503 can be adhered to the inside diameter of the main body 502 with an adhesive material as known in the art.

In this implementation, the insert material 503 has a constant thickness and is continuous throughout its length and circumference. However, the thickness may not be constant throughout a longitudinal axis of the main body and can be tapered, linear increase or decrease, non-linear increase or decrease, or stepped. The inner surface of the insert material 503 may also have a geometric pattern, raise portions, and non-raised portions, e.g., bumps, lines, any geometric shape and combinations of the same, on its surface. The insert material may also be any geometric pattern as one or more insert materials 503, e.g., any number of concentric rings of insert material, e.g., 1 or more. In one implementation, the insert material 503 includes two concentric rings of material one at or near the second end 506 and one at near the first end 504, thereby creating a discontinuity between the two insert materials 503.

The thickness of the insert material can be sized such that an inside diameter of the insert material 503 is about the same dimension, e.g., about 0.001 mm to about 2 mm or greater than an outside diameter of the container or inside diameter can even be less than an outside diameter of the container, thereby creating an interference fit with the container, such that some external force (other than gravity) is required to place or seat the container fully within a lumen 508 of the main bore 508 of the container 502. Also, as described herein, the inside diameter may be less than the outside diameter of the container, thereby creating a space between the outside dimension of the container and inside diameter of the insert 503, e.g., 2 mm or greater, between the outside diameter of the container and inside diameter of the insert material. In such configuration, different containers with different outside dimensions can be utilized with the same mixing apparatus.

FIG. 6A illustrates a bottom view of a mixing apparatus according to an implementation of the present disclosure. FIG. 6B illustrates a bottom view of a mixing apparatus according to an implementation of the present disclosure.

Referring to FIG. 6A, illustrating a bottom view of mixing apparatus 600 described herein. As explained herein the mixing apparatus includes a main body or housing 602, a first end, a second end, a lumen or bore extending from the first end to the closed second end. The second end of the main body 502 has a substantially flat base. A shaft 604 is arranged at an orthogonal configuration relative to the flat base of second end. The shaft 604 is configured and sized to be inserted into a receiving portion of a rotational device. The receiving portion of the rotational device is a chuck or a specialized type of clamp configured to releasable hold at least a portion of the shaft 604. The chuck or clamp or other attachment mechanism as known in the art is used to hold an object with radial symmetry, e.g., a cylinder. The main body 602 includes a y-axis 606, x-axis 608 and a center most portion 609 of the main body 602 is at an intersection of y-axis 606 and x-axis 608 is shown in FIG. 6A. In this implementation the shaft 604 has a center that is centered with the center 609 of the main body. That is, there is no offset and the lack of offset allows the mixing apparatus to spin in wobble free configuration.

Referring to FIG. 6B, in this implementation, the shaft 604 is in an offset orientation relative to a center 609 of the main body 602 or other connection mechanism. A center 611 of a shaft 604 is defined by an intersection of an x-axis 612 and y-axis 610 of the shaft 604. In this configuration, the offset 614 is measured from a center 609 of the main body 602 to a center 611 of the shaft 604 or other rotational connection mechanism described herein and is a range from about 0.001 mm to about 8 mm. When an offset 614 is utilized the main body wobbles during operation of the mixing apparatus. The larger the offset 614 the greater the wobble during operation can impart greater agitation to a container during operation of the mixing apparatus. It is believed that using an offset 614 may impart a faster rate of mixing the contents of container than using a mixing apparatus without the offset 614. This may be useful for mixing highly viscous contents in a container, e.g., glue or heavy pigmented products.

The ring 717 prevents the cap from falling off the main body and a cord or line 707 that is connected to the cap 701. The retaining mechanism 717 may be a separate component from the cap 701 or an integral unit or component with the cap 701, e.g., one single piece made via injection molding, laser welded, heat welded, sonic welded combinations of the same or other techniques as known art.

The apparatus 700 includes a main body or housing 702, a first end 704, a second end 706, a lumen or bore 708 extending from the first end 704 to the closed second end 706.

FIG. 19A illustrates a bottom perspective partial cross-sectional view of a mixing apparatus according to an implementation of the present disclosure. FIG. 19B illustrates a cross-sectional view along line A to A′ of a mixing apparatus according to an implementation of the present disclosure.

Referring to FIG. 19A-19B, a clutch 1900 is shown. The shaft 1902 is configured to be installed into a drill chuck and also configured as described herein. The drive shaft 1902 is molded into the lower clutch shaft. A side wall 1904 of the main apparatus 1901 is shown. A bottom 1908 of the apparatus includes a flat base.

As the drive shaft 1902 is spun in a drill the clutch 1985 and 1987 with the friction surface 1984 will grasp onto the main apparatus 1904 so it will spin. If the rotation of the drill becomes faster than required the friction surface of the clutch 1985 will slip against the main apparatus 1904 causing the main apparatus to slow down. The friction clutch will also fully disengage and slip if the user grabs onto the main apparatus while it is spinning to prevent injury. Alternatively, other clutch designs may be utilized.

FIG. 20 illustrates a method of operating the mixing apparatus according to an implementation of the invention.

Referring to FIG. 20, the method is depicted with reference to number 2000 for mixing contents of a container. In this implementation, the method 2000 includes retrieving a mixing apparatus in step 2002. The mixing apparatus may include any mixing apparatus described herein and combinations of same. In step 2004, a rotational device is retrieved. In step 2008, the rotational device is releasably attached to the mixing apparatus. However, the rotational device and mixing apparatus may be one integral unit and not releasable attached.

In another implementation, in step 2008, a shaft from the mixing apparatus is inserted into a receiving portion of a rotational device. The receiving portion of the rotational device is a chuck or a specialized type of clamp configured to releasable releasably hold at least a portion of the shaft.

In another implementation, in step 2008, when using a mixing apparatus that does not include a shaft, e.g., as described with reference to FIGS. 16A-16C, a first end of a spindle is inserted into a receiving portion of a rotational device. Again, the receiving portion of the rotational device is a chuck or a specialized type of clamp configured to releasable hold at least a portion of the shaft. A second opposite end of the spindle is inserted into a receiving portion of a plate.

In step 2010, a container is arranged into a lumen or bore of the mixing apparatus. In this implementation, the container is arranged such that a base portion touches a bottom portion of the mixing apparatus. The container is not attached to the mixing apparatus as described herein.

Since the mixing apparatus and/or housing has no attachment mechanism or means for the container to couple or releasably attach the container to the housing, the container can rotate at a different rotational velocity as compared to the main body during operation for at least an amount of time. The container rotates as it is in contact with at least one of a portion of an inner wall or bottom of the mixing apparatus during operation. Frictional forces, centrifugal forces and/or other forces cause the container to rotate as the main body rotates. However, typically, the container rotates at a lower rotational velocity even after a startup time as compared to the main body. The startup time is about three seconds or less depending on the RPM of the rotation device. A lower RPM, e.g., 100 RPM or less, there may be no startup time and the container and main body rotate always at the same velocity. At a higher RPM, e.g., 1500 or greater, a startup time of about two seconds or less, e.g., five tenths of a second, the container and main body rotate at different velocities. In addition, an angle of rotation may also affect the startup time. The angle of rotation is described herein. In addition, when turning off the rotational device the container may continue to rotate even though the main body has stopped rotation.

In one implementation, since the container is not attached, secured, or coupled to the main body of the mixing apparatus or another portion of the mixing apparatus. There is also no mechanism to provide a compression force to secure or attach any portion of the container to the main body. The container can rotate freely in the main body; therefore, a user can stop or slow the rotation of the container by holding or cradling a portion of the container and the main body continues to rotate.

In one implementation, the rotation device is configured to rotate in a range from about 1 RPM to about 1500 RPM or greater. In one implementation, the RPM for mixing a typical aerosol can or paint container, is in a range from about 700 RPM to about 1300 RPM or greater.

Optionally, a user may rotate the main body about a central axis at an angle of rotation from about 0 degrees to about 360 degrees. When using an angle of rotation from about 0 degrees to about 180 degrees a user does not need to cradle or hold any portion of the container. At about 0 degrees and about 180 degrees the central axis is substantially parallel with a floor that a user is standing on.

A user can also rotate the main body from about 180 degrees to about 360 degrees while cradling at least a portion of the container during operation with a user's hand in order to prevent the container from falling out of the lumen due to gravity. In this implementation, a user will start operation (step 2012) of the rotational device while simultaneously cradling or holding a portion of the container to prevent it from falling out of the lumen. The container can move along the central axis as controlled by the user; this movement can occur during rotation of the main body or not during rotation of the main body.

In a preferred embodiment, the angle of rotation is about 25 degrees to about 35 degrees or 155 degrees to about 165 degrees as it allows the container to be in substantially constant contact with a wall and bottom of the mixing apparatus.

Optionally and/or alternatively, the rotation device may be not hand held, but is fixed position and stationary position that does not require a user to hold the rotation device. The rotational device is also at a fixed rotational angle or variable rotational angle. This type of rotational device allows for hands free operation. Moreover, during operation multiple containers can be utilized with or without turning off the rotational device during operation. By way of illustrative implementation, a first container is added to a mixing apparatus at about a 90 degree angle with a fixed rotation device. The rotation device is activated for a first period of the time. The user can remove the first container without turning off the rotational device and then add a second rotational device and repeat any number of times. A fixed rotational device also permits longer period of mixing to avoid user fatigue.

In step 2012 a user can operate the rotation device, e.g., drill, in a clock-wise or counter clock-wise rotation. After a predetermined time, the container is removed in step 2014. During step 2014 the rotational device rotating the main body may still be in operation, may be slowed to a predetermined RPM, or turned off. Optionally, in step 2016, the process is repeated.
