DETAILED DESCRIPTION

[0046] The present disclosure relates to aspects of a blending apparatus that help reduce the amount of effort needed to achieve a desired blend of various products. One aspect relates to a blender jar assembly that includes a blending jar and a scraper lid releasably mounted to the blending jar. The jar has a generally cylindrical shape with an interior surface also having a cylindrical configuration. The scraper lid includes at least one scraper member mounted thereto which extends into the interior of the jar when the scraper lid is releasably mounted to the jar. The scraper typically contacts the inner surface of the jar along at least a portion of the length of the scraper. The scraper may be arranged and configured to disrupt a rotational flow of food particles (e.g., partially blended food particles) within the jar to provide improved blending. The scraper may also assist in scraping food particles off a portion or all of the inner cylindrical surface of the jar so that dislodged food particles may enter into the rotational flow of food particles for further blending.

[0047] The scraper may be rotatable within the jar while the blender is running (i.e., a blending blade within the blending jar is rotating at high speeds). The scraper may be rotatable with the scraper lid in a direction opposite the rotational direction of the blender blade. In some arrangements, it may be possible to rotate the scraper with the scraper lid in the same direction as the blade rotation. There may be benefits to the scraper being positioned within the jar without rotating the scraper relative to the jar.

[0048] The flow disruption and scraping function of the scraper within the jar may help continually reintroduce the food particles into an area of the jar where the food particles may be acted upon by the rotating blending blade. The scraper may reduce the amount of time the food particles are in contact with the inner surface of the jar, thereby reducing the amount of time required to reach a desired blended consistency of the food particles and in some cases, obtain liquification of the food particles.

[0049] The scrapers may have various shapes, sizes, and orientations relative to the scraper lid and jar. In one example, the scraper includes a contoured or curved portion along its length. The scraper may be contoured or angled circumferentially. The scraper may also be contoured or angled radially inward. The scraper may have a contour or curvature along its length that matches a curvature or angle of the inner surface of the jar from a top open end to a bottom closed end of the jar to help maintain contact of the scraper with the inner surface of the jar along substantially an entire length or a portion of the length of the scraper. The curvature and other features of the scraper may improve the scraping function and flow disruption by limiting the ability of food particles to become trapped or packed underneath a portion of the scraper or in the area between the scraper and the area within the jar where the blending blade operates. The contour and other features of the scraper may help lift and remove food particles from the inner surface of the jar to help reintroduce the food particles to a rotational flow of food particles in the jar or to a location within the jar where the food particles may be acted upon by the blending blade when the blade is operating (i.e., a blade area).

[0050] The scraper lid may include a pass-through hole into which additional food particles may be delivered into the jar while the scraper lid is mounted to the jar. The scraper lid may include a lid handle that extends in an opposite direction from the scraper. The lid handle may provide a graspable member or portion that the user may use to apply a rotational or torque force to the scraper lid to rotate the scraper within the jar. The pass-through hole may extend through the lid handle.

[0051] The jar may have a shape and size that may provide easier and/or improved blending of small amounts of food particles in a shorter amount of time with less effort as compared to using jars of different size and shape.

[0052] Referring now to FIGS. 1-10, an example blender apparatus 10 having a blending jar and scraper lid with features described above is shown and described with greater detail. The blender apparatus 10 includes a base 12 having a motor 14 positioned therein, a blending jar 16 releasably mounted to the base 12, a blending blade 18 positioned in the blending jar 16, and a scraper lid 20 releasably mounted to the blending jar 16. Mounting the scraper lid 20 to the blending jar 16 positions a pair of first and second scraper members 52, 54 within the blending jar 16. Rotating the scraper lid 20 in clockwise (CW) and counterclockwise (CCW) directions relative to the blending jar 16 a shown FIG. 1 moves the first and second scraper members 52, 54 along an inner surface of the blending jar 16. The first and second scraper members 52, 54 may disrupt rotational flow of food particles in the blending jar 16 whether the first and second scraper members 52, 54 are held stationary or rotated in the clockwise or counterclockwise directions while the blending blade 18 is in operation. Rotating the first and second scraper members 52, 54 may move food particles held within the blending jar 16 (e.g., detach or lift the food particles off of the inner surface of the blending jar 16 and move the food particles axially toward or away from the blending blade 18). The shape and size of the first and second scraper members 52, 54 may help direct food particles into an area within the blending jar 16 wherein the food particles may be acted upon by the rotating blending blade 18.

[0053] The base 12 may include a jar mounting portion 22. A driveshaft 24 may extend through the base 12 for access adjacent to the jar mounting portion 22. The driveshaft 24 may be operably connected to the motor 14, wherein operation of the motor 14 rotates the driveshaft 24. The driveshaft 24 may be operably connected to the blending blade 18 when the blending jar 16 is mounted to the base 12.

[0054] The blending jar 16 includes an open end 30, a closed end 32, a sidewall 34, a jar handle 36, a spout 37, and a mounting portion 38 (see FIG. 2). The mounting portion 38 may mate with the jar mounting portion 22 of the base 12 to provide a releasable connection of the blending jar 16 to the base 12. A lid recess 39 may be formed at the open end 30 and sized to receive the scraper lid 20. A portion of the scraper lid 20 may contact the lid recess 39. Another portion of the scraper lid 20 may contact an inner surface 40 of the blending jar 16. The blending jar 16 may also include an outer surface 42, an inner volume or cavity 44 defined by the inner surface 40, an inner diameter D.sub.1, and ajar inner surface angle (see FIG. 3).

[0055] In one embodiment, the inner diameter D.sub.1 may be in the range of about 3 inches to about 6 inches, and more preferably about 3 inches to about 4 inches. The jar inner surface angle , which may be defined as a taper angle from the top open end 30 to the bottom closed end 32, is typically in the range of about 1 to about 10, and more preferably about 3 to about 5.

[0056] The inner, cylindrical volume 44 (FIG. 2) may have a length L.sub.1 extending from the closed end 32 to the lid recess 39 (see FIG. 3). The inner volume 44 may also have a length L.sub.2 that extends from the lid recess 39 to an upper most portion of the blending blade 18 (i.e., a top surface of a tip 46 of the blending blade 18) (see FIG. 3). The lengths L.sub.1, L.sub.2 are typically in the range of about 2 inches to about 12 inches, although many other sizes are possible.

[0057] The blending jar 16 may have an inner volume 44 that generally corresponds to a cylindrical shape, which may be circular in cross-section (see FIG. 10). Providing the circular cross-section for the blending jar 16 may provide improved contact between the first and second scraper members 52, 54 of the scraper lid 20 with the inner cylindrical surface 40 of the blending jar 16. A circular cross-section may also provide easier rotatability of the scraper lid 20 relative to the blending jar 16, and rotatability of the scraper lid 20 with a relatively constant amount of friction (particularly given a collection of food particles on the inside surface of the jar) and corresponding torsional force applied to the scraper lid 20. Other shapes and sizes are possible for the blending jar 16 that would provide at least some contact between the first and second scraper members 52, 54 and the inner surface 40 when the scraper lid 20 is rotated relative to the blending jar 16.

[0058] Referring now to FIGS. 4-9, the scraper lid 20 includes a base portion 50, the first and second scraper members 52, 54 described above, a lid handle 56, and a lid aperture 58. The scraper lid 20 may be integrally formed as a single piece. The scraper lid 20 may comprise a polymer material, such as, for example, a polycarbonate material, or any other suitable material known to those skilled in the art. In some examples, the first and second scraper members 52, 54 may be generally rigid along their lengths. In one example, the first and second scraper members 52, 54 may include a plurality of layers or include an embedded member that provides additional rigidity and strength.

[0059] The base portion 50 may include a lip 60, a periphery sealing surface 62, a top surface 64, and a bottom surface 66 (see FIGS. 4-5). The lip 60 may be sized to extend into the lid recess 39 of the blending jar 16 (see FIG. 3). The periphery sealing surface 62 may extend into and maintain contact with the inner surface 40 of the blending jar 16 (see FIG. 3). The periphery sealing surface 62 may provide a fluid tight seal between the scraper lid 20 and the blending jar 16. Other arrangements are possible for the scraper lid 20, including, for example, an arrangement in which the lip 60 rests on an upper most surface of the blending jar 16 and the periphery sealing surface 62 contacts a surface of the lid recess 39.

[0060] The first and second scraper members 52, 54 extend from the bottom surface 66 of the base portion 50. The lid handle 56 extends from the top surface 64 of the base portion 50. The first and second scraper members 52, 54 may extend from the base portion 50 in a direction opposite the direction of extension of the lid handle 56 from the base portion 50.

[0061] The first and second scraper members 52, 54 may be integrally formed as a single, unitary piece with the base portion 50. Alternatively, the first and second scraper members 52, 54 may be separately formed from the base portion 50 and mounted either permanently or releasably to the base portion 50. The first and second scraper members 52, 54 may be replaceable portions of the scraper lid 20.

[0062] The first and second scraper members 52, 54 may each include first and second ends 70, 72, a bevel 74, a leading edge 76, and a trailing edge 78. The first and second scraper members 52, 54 may also have a scraper length L.sub.3 (see FIG. 7) and a width W (see FIG. 4). The bevel 74 may be defined along the leading edge 76 and extend across at least a portion of the width W. The bevel 74 may assist in lifting or moving the food particles positioned on the inner surface 40 of the blending jar 16. The bevel 74 may have a bevel angle .sub.4 as shown in FIG. 8. The bevel angle .sub.4 may be in the range of, for example, about 5 to about 60, and more preferably about 20 to about 30.

[0063] Referring to FIG. 6, the first and second scraper members 52, 54 may extend at a circumferential extension angle .sub.1 relative to a central axis of the scraper lid 20. The circumferential extension angle .sub.1 may be in the range of, for example, about 5 to about 45, and more preferably about 20 to about 30.

[0064] Referring to FIG. 7, the first and second scraper members 52, 54 may have a radial extension angle 82 relative to a central axis of the scraper lid 20. The radial extension angle .sub.2 may substantially mirror the jar surface angle . The radial extension angle 82 may be in the range of, for example, about 1 to about 10, and more preferably about 2 to about 5. The radial extension angle .sub.2, alone or in combination with the jar surface angle , may assist in inserting the first and second scraper members 52, 54 into the inner volume 44 of the blending jar 16. The first and second scraper members 52, 54 may partially contact the inner surface 40 of the blending jar 16 during insertion, and completely contact the inner surface 40 only after full insertion of the scraper lid 20 into its final resting position within the lid recess 39 (see FIG. 3). In other arrangements, the radial extension angle .sub.2 is close to 0 and the first and second scraper members 52, 54 are deflected radially inward as the scraper lid 20 is mounted to the blending jar 16.

[0065] The first and second scraper members 52, 54 may taper to a smaller width W towards the second end 72, as shown in FIG. 6. The taper at the second end 72 may have a taper angle .sub.3 (see FIG. 6). The taper angle .sub.3 may be in the range of, for example, about 1 to about 30, and more preferably about 5 to about 20. The taper angle .sub.3 may arrange the leading edge 76 at the second end 72 to be substantially parallel with the central axis of the scraper lid 20.

[0066] The first and second scraper members 52, 54 may be equally spaced apart around a circumference of the base portion 50 as shown in at least FIG. 8. Other arrangements may include different orientations and spacing between the first and second scraper members 52, 54. Furthermore, different numbers of scraper members may be possible. In one example, a single one of the scraper members 52, 54 is provided on the scraper lid 20. In other arrangements, three or more scraper members are positioned on the scraper lid 20. The scraper members shown in FIGS. 1-10 have the same length L.sub.3. In other arrangements, at least some of the scraper members have different lengths than the others. Similarly, the various scraper members of a given scraper lid may have different widths and angles .sub.1-4.

[0067] Referring to FIG. 10, an example food rotational flow R is shown in the blending jar 16 with the scraper lid 20 mounted to the blending jar 16. The first and second scraper members 52, 54 direct the food particles in the food rotational flow R in a radially inward direction A. This directing of the food particles radially inward may be referred to as flow disruption or disruption of the food rotation flow R. Rotating the scraper lid 20 in the clockwise or counterclockwise direction, or maintaining the scraper lid 20 in a stationary rotated position may all provide the radially inward directed flow disruption for the food rotational flow R.

[0068] Typically, rotating the scraper lid 20 in either the clockwise or counterclockwise direction may also help detach or lift food particles from the inner surface 40 of the blending jar 16. The first and second scraper members 52, 54 may have the bevel feature 74 along the leading edge 76, and a relatively blunt surface along the trailing edge 78. The bevel and blunt features of the leading and trailing edge 76, 78, respectively, may have different advantages related to moving food particles in the blending jar 16 depending on, for example, the type of food article being blended and whether or not the blending blade 18 is being operated. Other features of the first and second scraper members 52, 53, such as, for example, any of the angles .sub.1-3, may provide certain advantages related to flow disruption and food scraping when rotating the scraper lid 20 in either the clockwise or counterclockwise direction.

[0069] Referring now to FIGS. 11-17C, another example blender apparatus 100 is shown and described. The blender apparatus includes a blending jar, a scraper lid assembly, and recessed lid assembly. The blender apparatus 100 may have many of the same or similar features as the blender apparatus 10, including the base 12 having a motor 14 positioned therein as described above with reference to FIG. 1. A blending jar 116 may be releasably mounted to the base 12. A blending blade 118 is positioned in the blending jar 116. The blending blade may include tips 146 (see FIG. 13B) A scraper lid 120 may be releasably mounted to the blending jar 116. A recessed lid assembly 180 may be releasably mounted to the blending jar 116 in place of the scraper lid 120.

[0070] The scraper lid 120 includes a pair of first and second scraper members 152, 154 that extend into the blending jar 116. Rotating the scraper lid 120 relative to the blending jar 116 moves the first and second scraper members 152, 154 along an inner surface of the blending jar 116. The first and second scraper members 152, 154 may disrupt rotational flow of food particles in the blending jar 116. Rotating the first and second scraper members 152, 154 may move food particles held within the blending jar 116 (e.g., detach or lift the food particles off of the inner surface of the blending jar 116). The shape and size of the first and second scraper members 152, 154 may help direct food particles into an area within the blending jar 116 wherein the food particles may be acted upon by the rotating blending blade 118 as described above related to blender apparatus 10. The first and second scraper members 152, 154 may have the same or similar features as the first and second scraper members 52, 54 described above.

[0071] The blending jar 116 may include many of the same or similar features as described above for the blending jar 16. The blending jar 116 may also include an outer surface 131 along a sidewall 134 (see FIG. 11) that is contoured or shaped. The contour or shape of outer surface 131 may provide additional strength to the blending jar 116. The contour or shape of the outer surface 131 may provide improved aesthetics for the blending jar 116. The blending jar 116 may be constructed to permit stacking of a plurality of blending jars 116 one inside of the other.

[0072] Referring now to FIGS. 11, 12A-B, 14A-D and 15A-B, the scraper lid 120 includes a base portion 150, the first and second scraper members 152, 154 described above, a lid handle 156, a lid aperture 158, and a cap 157. The base portion 150, first and second scraper members 152, 154, and lid handle 156 may be integrally formed as a single piece. Alternatively, the first and second scraper members 152, 154 may be separately formed from the base portion 150 and mounted either permanently or releasably to the base portion 150. The first and second scraper members 152, 154 may be replaceable portions of the scraper lid 120. The cap 157 may mount to the lid handle 156 and cover the lid aperture 158.

[0073] The scraper lid 120 may be mounted to the blending jar 116 at an open upper end of the blending jar 116. A portion of the scraper lid 120 may extend into the blending jar 116 and contact an inner surface of the blending jar 116. At least one portion of the scraper lid 120 may create a fluid tight seal with a portion of the blending jar 116 (e.g., see FIG. 12B).

[0074] The first and second scraper members 152, 154 may be equally spaced apart around a circumference of the base portion 150 as shown in at least FIG. 14D. Other arrangements may include different orientations and spacing between the first and second scraper members 152, 154. Other embodiments include different numbers of scraper members (e.g., a single scraper member or three or more scraper members). The first and second scraper members may be generally planar in configuration or have a helical twist to their configuration. The first and second scraper members 152, 154 may have the same or different physical properties such as, for example, lengths, widths, thicknesses, contours, taper features, angled arrangements, and other features.

[0075] The cap 157 has a generally circular construction that matches the generally circular shape of the lid aperture 158. The cap 157 may include a cap sealing surface 159 (see FIGS. 15A-B). The cap sealing surface 159 may contact and provide a seal with a portion of the lid handle 156. FIG. 12B shows the cap sealing surface 159 contacting an internal surface of the lid handle 156 to form a fluid tight seal. Other portions of the cap 157 may form sealing interfaces with portions of the lid handle 156.

[0076] The recessed lid assembly 180 includes a recessed lid 182 and a splash lid 184 (see FIGS. 11, 13A-B and 16A-17C). The recessed lid 182 is configured to releasably mount to the open top end of the blending jar 116. The splash lid 184 is configured to releasably mount to the recessed lid 182. The recessed lid 182 includes a spout 186, a recess 188, a recess opening 190, and a seal surface 189 (see FIGS. 16A-B). The spout 186 may further accommodate the addition of ingredients into the blender jar 116 while the blending blade 118 is operating and the splash lid 184 is in place. The spout 186 provides a place to pour liquids that are intended to be add to the contents of the blender jar 116 while the blender apparatus 100 is in operation without having to remove the recessed lid 182 or splash lid 184 in order to do so. The recess opening 190 may provide access into the blending jar 116 while the recessed lid 182 is mounted to the blending jar 116. For example, a user may insert ingredients through the recess opening 190 and into the blending jar 116 while the blending blade 118 is operating.

[0077] The splash lid 184 may include a base 191, a connection portion 192, a support portion 194, and a plurality of cutouts 196 (see FIGS. 17A-C). The connection portion 192 and support portion 194 extend from and are supported by the base 191. The connection portion 192 is configured to provide a releasable connection between the recessed lid 182 and the splash lid 184. The connection portion 192 may include a snap-fit feature that provides a snap-fit connection between the recessed lid 182 and the splash lid 184. A portion of the connection portion 192 may extend through the recess opening 190 in the recessed lid 182 (see FIG. 13B). The connection portion 192 may include a plurality of connection members 192A-B. The connection members 192A-B may operate independently. The connection portion 192 may have many different types of connection features that assist in releasably connecting the splash lid 184 to the recessed lid 182.

[0078] The support portion 194 may operate to support the splash lid 184 on the recessed lid 182 (see FIG. 13B). The support portion 194 may space apart the base 191 from surfaces of the recess 188. The cutouts 196 may be formed in the support portion 194 at spaced apart locations around a perimeter of the support portion 194 (see FIG. 17B). The cutouts 196 may provide a flow path from inside the splash lid 184 into the recess 188, and out of the recessed lid assembly 180 through the spout 186. The splash lid 184 may more effectively accommodate the addition of ingredients into the blending jar 116 while the blending blade 118 is in operation. The splash lid 184 provides a place to pour liquids that are intended to be added to the contents of the blending jar 116 while the blender apparatus 100 is in operation without having to remove the splash lid 184 or recessed lid 182 in order to do so. The splash lid 184 may provide at least some venting of the blending jar 116 to help relieve internal pressure within the blending jar 116 generated during operation of the blender apparatus 100.

[0079] Referring now to FIG. 18, the blending jar 116 may include a blending blade 218 having tips or winglets 246. The tips 246 may be positioned adjacent to the internal surface 140 of the blending jar 218. The tips 246 may extend at least partially vertically upward closely adjacent the internal surface 140. The tips 246 may extend upward more (see 246A) or less to provide an optimal scraping or blending function. The extended tips 246A may be referred to as scraper members or scraper portions of the blending blade 218. The tip extensions 246A may be integrally formed as a single piece with the blending blade 218. In some embodiments, the tip extensions 246A may be formed as separate pieces that are connected to the blending blade 218 in a separate assembly step.

[0080] The tip extensions 246A may provide a scraper function, similar to the scraper members described herein with reference to lids 20, 120. For example, the extended tips 246A, or the regular tips 246, may help move food particles off of the internal surface 140. The extended tips 246A may help move food particles in an axial direction toward or away from other portions of the blending blade 218. The extended tips 246A may be arranged and configured to disrupt rotational flow of food particles within the internal volume. The extended tips 246A may converge toward the inner cylindrical wall 140 (as shown in FIG. 18) or may extend parallel to and closely adjacent the wall 140.

[0081] A portion of the extended tips 246A may alternatively be in contact with the internal surface 140. In some arrangements, the extended tips 246A may be positioned adjacent to the internal surface 140, perhaps with a very slight frictional fit, or remain slightly out of contact with the internal surface 140.

[0082] While this invention has been described with reference to certain specific embodiments and examples, it will be recognized by those skilled in the art that many variations are possible without departing from the scope and spirit of this invention. The invention, as described by the claims, is intended to cover all changes and modifications of the invention which do not depart from the spirit of the invention. The words including and having, as used in the specification, including the claims, shall have the same meaning as the word comprising.
