DETAILED DESCRIPTION

Certain exemplary embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one exemplary embodiment may be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.


Various exemplary hair curlers for use with a hair care appliance, such as a hair dryer, and/or an attachment thereof are provided herein. The hair curlers address a number of shortcomings of existing hair curlers. For example, existing hair curlers may be challenging to place hair within the hair, and once placed therein, may not adequately secure hair onto the hair curler causing it fall out of the user's hair. Some hair curlers can be bulky, awkwardly shaped, or can include clips or locking mechanisms which can be difficult to manually manipulate. It can be challenging to easily place hair curlers in desired locations close to the roots of hair or in difficult to reach locations, such as in hair located at the back of the user's head. Clips can be required to maintain a hair curler at a desired location and the clips can be easily lost or misplaced. Some hair curlers require the user sleep with the hair curlers in place in order to form a long-lasting, well-formed curl. The material of the hair curler can also affect the curl produced and ease of use of the hair curler. For example, curlers that include a Velcro material can cause hair to be entrapped therein during application or removal.


Some hair curlers are heated in order to form or set a curl in hair and can burn the user's hand or scalp if not handled properly. It can be difficult to easily remove the hair curler without ruining the newly created curl. When curling hair via a dedicated curling device or a curling attachment of a hair care appliance, it can be difficult to keep hair wrapped around a barrel of the device or attachment. The improved hair curler described herein addresses these shortcomings.


Creating a well-formed, long-lasting curl can require particular skill to perform. A number of factors can determine the shape, volume, and longevity of a curl. A curl can include a stem portion, a curl portion, and a base portion as shown in FIG. 17B. The stem portion of the curl can be a length or an amount of hair extending from the roots of the hair to the first arc of a first curl. The stem can be important as it can determine the direction of a curl, and the volume of the curl. The volume of the curl can be based on what direction the hair is wrapped around the curler. The curl portion can be the portion of hair that wraps around the hair curler. The size of the curl can correspond to the size of the hair curler that is applied. A bigger hair curler will impart a larger curl. The base portion of the curl can be a distance from last curl of the curl portion to the base of the curler. Ideally, the base portion will not be longer than the diameter of the hair curler or else the curls will be created further away from the roots resulting in lower volume, poorly formed curls. Placing the hair curler close to the roots of the hair can form higher volume, more robust curls. The hair pod described herein has a number of design features configured to improve the shape, size, location, and permanency of curls.


In one embodiment, a hair pod is provided. The hair pod can be configured for use with a hair curler having a shaft around which hair can be wrapped for curling. The hair pod can include a cap that can mate with an end (or end cap) of the hair curler and a base that can slide along a shaft of the hair curler. A user can position the base onto the shaft of the hair curler and can place the cap onto the end of the hair curler. The user can wrap hair around the shaft of the hair curler in between the cap and the base to initiate curling of the hair. The base can be slidably advanced along the shaft to mate with the cap. The wrapped hair can be retained between the cap and the base within a chamber or entrapment area formed between the cap and the base. A user can then remove the hair pod retaining the hair therein from the hair curler. The user can leave the hair pod attached to their hair for a period of time to set the curl formed via the hair pod.


The hair pod described herein can provide a number of advantages over existing hair curlers. For example, the hair pod includes a low-profile, compact design which is visually appealing, sleek, and easily-handled for curling hair. Because the hair pod is configured for attachment to a shaft of a hair curling device, it is more efficient to use than other curling devices and methods which require use of a hair curling device to first curl a user's hair and subsequent insertion and placement of a hair curler to hold and set the curled hair. The hair pod described herein can advantageously be placed closer to the scalp to create better-formed curls along an entire length of hair than existing hair curlers. The convenient coupling of the cap and base make capturing hair within the hair pod easier than other hair curler designs which can require clips or complicated fixing means to retain hair with respect to a hair curler. In addition, one or more portions of the hair pod described herein include heat-resistant materials to protect a user's hand and/or scalp from accidental burns. Advantageously, these features can provide an enhanced styling experience, particularly for producing well-formed curls along the entire length of a user's hair compared to other hair curlers.



FIGS. 1A-9 illustrate exemplary embodiments of a hair pod configured for detachable coupling with a hair curler. In one embodiment, shown in FIGS. 1A-4, a hair pod 100 is provided having a cap 102 and a base 104. The illustrated cap 102 is a generally concave structure with a central cylindrical housing 110 having a central opening 106 extending therethrough, and a shield 116 arranged around the cylindrical housing 110. The base 104 is an annular structure and having a central opening 108 configured to slidably receive a curler device.


As shown in more detail in FIG. 2A, the cylindrical housing 110 of the cap 102 can include a plurality of ribs 124 arranged longitudinally along the inner surface thereof. The cylindrical housing 110 can be configured to slidably couple with an end cap of a hair curler as will be described later. The housing 110 can include a high-friction material overmolded atop the housing 110 to retain the housing 110 on the end cap of the hair curler. In some embodiments, the high-friction material can include a thermoplastic elastomer. In some embodiments, the thermoplastic elastomer can have a Shore hardness of 55-65 on the durometer scale. The lower portion of the cylindrical housing 110, as shown in FIG. 2B, can include a beveled edge 126 to improve the ease of coupling the cap 102 to the end cap of a hair curler.


The shield 116 can be arranged around the central opening 106. The shield 116 can have various configurations, but in the illustrated embodiment the shield 116 has a plurality of arms 128 extending radially from the central opening 106 that together define a generally concave inner cavity or entrapment area 122. Although the embodiment of FIGS. 1A-4 illustrate a shield 116 having 4 radially extending arms, more or less arms 128 can be envisioned. The shield 116 (and arms 128) can include a first portion 118 extending radially outward from the central opening 106 and a second portion 120 extending substantially parallel to a longitudinal axis extending through the central opening 106. In other words, each arm 128 can be curved or in the form of a rounded L-shape.


In some embodiments, the shield 116 can include a plurality of shield projections 130 extending from the inferior surface 132 of the first portion 118 of the shield 116 toward the base. The shield projections 130 can extend into the entrapment area 122 and toward the base 104. In this way, the shield projections 130 can contact hair within the entrapment area 122 and improve the ability of the hair pod 100 to hold hair therein for curling.


The second portion 120 of the shield 116 can include a notch 134 configured in a support 136 that extends radially inward from the inferior surface 132 of the shield 116 toward the cylindrical housing 110. The support 138 can extend along the length of the arms 128 and can be configured to provide support to the arms 128. The notch 134 can have an annular shape and can be configured to mate, via friction fit or inference fit, with a flange of the base 104 as will be described later.


Each of the arms 128 can include an overmolded portion 138 surrounding the second portion 120 of the shield 116. In some embodiments, the overmolded portion 138 can include a high-friction material overmolded atop the second portion 120 of the shield 116 (e.g., at the lower end of the arm 128). In some embodiments, the overmolded portion 138 can be formed on, partially around, or fully around the second portion 120. The high-friction surface of the overmolded portion 138 can help to retain the hair pod 100 close to the scalp of a user for tighter, more well-formed curls and can also provide a high-friction surface to engage an end of the hair that is retained within the entrapment area 122. In this way, the hair pod 100 can advantageously provide a more secure engagement with a user's hair to improve the shape of curls. In some embodiments, the high-friction material can include a thermoplastic elastomer. In some embodiments, the thermoplastic elastomer can have a Shore hardness of 55-65 on the durometer scale.


As indicated above, the hair pod 100 can also include a base 104 configured to mate with the cap 102. As shown in detail in FIGS. 3A-3B, the base 104 can have an annular shape with a central collar 140 defining a central opening 108. In some embodiment, the inferior surface 158 of the base 104 can be hollowed out (as shown) for weight reduction. In some embodiments, the inferior surface 158 may not be hollowed out and can be substantially planar across its diameter. In some embodiments, one or more portions of the base 104 can include a heat-resistant material to protect a user's hands or scalp when using the hair pods described herein.


A flange 142 can extend radially outward from the collar 140 and can include a plurality of flange projections 148 extending from an upper surface of the flange 142 into the entrapment area 122. The plurality of flange projections 148 can include a first set of flange projections 144 and a second set of flange projections 146 interleaved with the first set of flange projections 144. The first set of flange projections 144 can have a height that is greater than the second set of flange projections 146 or vice versa. In some embodiments, the height of the flange projections 148 can be equal. In some embodiments, the number, spacing, or arrangement of flange projections 148 can vary from the number, spacing, or arrangement shown in FIGS. 3A-3B.


The base 104 can also include a second flange 150 positioned below and extending from the flange 142. An upper surface 152 of the second flange 150 can provide an abutment surface at which terminal ends (e.g., farthest from the cylindrical housing 110) of the arms 128 contact the second flange 150 when the cap 102 is coupled to the base 104.


The central opening 108 in the annular collar 140 can have a variety of shapes and sizes, and the particular configuration can vary depending on the configuration of the curler device that the base is adapted to slide onto. In the illustrated embodiment, the central opening 108 has an irregular or non-circular shape with a plurality of adjoining segments 114 defining an inner surface of the annular collar 140 and forming a circumferential shape of the central opening 108. The plurality of adjoining segments 114 can be configured to prevent rotational slippage or displacement of the base 104 relative to a longitudinal shaft of a hair curler configured for use with embodiments of the hair pod described herein.


In the illustrated embodiment, the segments 114 include a first set of segments 154 that are interleaved between a second set of segments 156. The plurality of adjoining segments 114 can be configured to slidably couple with adjoining segments of a hair curler when the base 104 is attached to the hair curler. For example, the first set of segments 154 can be oriented in a first rotational direction that corresponds to a first rotational direction of adjoining segments of a first hair curler (such as a curler having segments oriented in a right-handed or clockwise direction configured to produce right-handed curls). The second set of segments 156 can oriented in a second rotational direction that corresponds to a second rotational direction of adjoining segments of a second hair curler (such as a hair curler having segments oriented in a left-handed or counter-clockwise direction configured to produce left-handed curls). When viewed in combination, each pair of first and second segments (or left and right segments) are separated by a peak or projection 160 with each segment being in the form of a valley. A smaller peak 162 separates adjacent segments as shown in FIGS. 3A and 3B.


An example of right-handed curls that can be formed using the hair pods and styling assemblies described herein is shown in FIG. 17A. The length of hair 502 extending from the user's head 500 can have a right-handed rotational direction (R) formed using the base 104 of the hair pod 100 coupled to a hair curler 8300 via the first set of adjoining segments 154. As shown in FIG. 17B, the length of hair 504 extending from the user's head 500 can have a left-handed rotational direction (L) formed using the base 104 of the hair pod 100 coupled to the hair curler 8300 via the second set of adjoining segments 156. The right- or left-rotational direction of the curl can be defined relative to a longitudinal axis extending along a portion of hair in which the hair pod described herein is attached. This axis can be defined with respect to any angle along which a user's hair extends from their head.


Advantageously, the arrangement of the adjoining segments 114 enables the hair pod 100 to be coupled ubiquitously with hair curlers having right and left-handed rotational directions without requiring separate hair pods with respective right and left-handed rotational directions. Thus, each hair pod 100 is configured to operate with rotationally different hair curlers thereby reducing the number of curling accessories needed by the user and improving the overall hair curling experience.


The cap 102 and the base 104 can mate to one another along a central longitudinal axis A of the hair pod 100 that extends through the central opening 108 of the base 104 and through the central opening 106 of the cap 102, as shown in FIG. 4. When coupled, the first portion 118 and the second portion 120 of the cap 102 can form a chamber or entrapment area 122 with the flange 142 where hair can be entrapped therein wrapping around the cylindrical housing 110. The notch 134 located at the terminal end (e.g., farthest from the central opening 106) of the second portion 120 of the shield 116 can receive therein the outer edge of the flange 142. The radius or curvature of the notch 134 can be sized to correspond to the curvature or radius of the outer edge of the flange 142 such that the notch 134 and the flange 142 can couple together via friction fitting or interference fitting. In some embodiments, the notch 134 and the flange 142 can couple together via snap fitting, with the arms flexing as they are advanced over the flange 142. As further shown in FIG. 4, the second portion 120 of the shield 116 can abut or otherwise rest upon the second flange 150 of the base 104 when the cap 102 is coupled with the base 104. This can provide an additional measure of support for the hair pod 100.


In another embodiment shown in FIGS. 5A-6, the hair pod 200 can have similar features performing similar functions as hair pod 100 described above, except where noted otherwise herein. For example, in this embodiment the base 204 of the hair pod 200 has a single flange 206 extending radially away from an annular collar 208. The flange 206 can lack flange projections, such as flange projections 148 shown in FIGS. 3A-3B. The cap 202 can include a plurality of arms 212 forming a shield 218 extending radially away from a central opening 216 of the cylindrical housing 222. Each arm 212 can include a notch 210 at a terminal end 214 of the arm 212. The flange 206 can be received within the notch 210 and the terminal end 214 can overhang the flange 206 as shown in FIGS. 5A-5B. When the base 204 and the cap 202 are coupled, the hair pod 200 can include an entrapment area 220 formed therebetween, as shown in FIG. 6. Hair can be wrapped around the cylindrical housing 222 within the entrapment area 220 to form curls in the hair.


In another embodiment shown in FIGS. 7A-8, the hair pod 300 can include similar features performing similar functions as hair pod 100 described above, except where noted otherwise herein. For example, in this embodiment the hair pod 300 includes a cap 302 and a base 304. The cap 302 includes a cylindrical housing 312 with a central opening 310 extending therethrough. The cylindrical housing 312 can include a gasket 314 positioned on an inner wall of the cylindrical housing 312. The gasket 314 can be formed from or can include a high-friction material to retain the housing 312 on the end cap of a hair curler. In some embodiments, the high-friction material can be a thermoplastic elastomer. In some embodiments, the thermoplastic elastomer can have a Shore hardness of 55-65 on the durometer scale.


The cap 302 can include a shield 316 having a substantially concave shape and including a first portion 318 extending radially away from the housing 312 and a second portion 320 extending longitudinally from the first portion 318 as shown in FIG. 8. The second portion 320 can be received within the cap 302 when coupled with the base 304. An entrapment area 330 can be formed between the cap 302 and the base 304 as shown in FIG. 8. In some embodiments, the second portion 320 can include scalloped circumferential edge 322 to provide additional surface area for engaging a user's hair. The scallops can have a variety of protruding portions 332 interspersed between recessions 334. A variety of different arrangements and dimensions of the scallops along the edge 322 can be envisioned.


The base 304 can include a first flange 308 that extends radially from an annular collar 324 having a central opening 328 extending therethrough. The first flange 308 can be formed from a substantially rigid material and can be coupled with a second flange 306 extending radially away from the first flange 308. The second flange 306 can be formed from a substantially flexible material. In this way, the second flange 306 can be reversibly configured with respect to the first flange 308 to accommodate different rotational configurations of a hair curler, as well be described later. In some embodiments, the base 304 may not include a second flange 306 and the first flange 308 can extend radially away from the annular collar 324 as shown by the flange 406 in the base 404 shown in FIGS. 11 and 15. In these embodiments, the cap 402 can abut the upper surface 408 of the base 404 when coupled to the cap 402, as shown in configuration 2 of FIG. 15.


As shown in FIGS. 7B-9, the base 304 can also include a plurality of adjoining segments 326 defining the central opening 328 through the annular collar 324. The plurality of adjoining segments 326 can be configured to correspond to adjoining segments configured on a hair curler to which the base 304 can couple. The base 304 can be reversibly transformed from a first configuration associated with a hair curler with a first rotational direction to a second configuration associated with a hair curler having a second rotational direction that is opposite that of the first rotational configurations.


For example, FIGS. 9A-9C illustrate a series of configurations of the base 304 as it is transformed from the first configuration (e.g., associated with a hair curler having a first rotational direction) to the second configuration (e.g., associated a hair curler having a second, opposite rotational direction. As shown in FIG. 9A, the base 304 and flange 306 can be configured for use with a hair curler having adjoining segments oriented in a first rotational configuration (R) for forming right handed curls. In this configuration the base has a concave shape. If a user desires to form left handed curls, the user can flip the base 304 over as shown in FIG. 9B. In this configuration the base 304 has a convex shape. Continuing from the configuration, the user can change the orientation of the second flange 306 by turning the second flange 306 upward to return the base 304 to a concave shape as shown in FIG. 9C. In this configuration, the base 304 and the flange 306 are now configured for use with a hair curler having adjoining segments oriented in a second rotational configuration (L) for forming left handed curls


In combination with the reversible configuration of the second flange 306, the plurality of adjoining segments 326 can enable the hair pod 300 to be used with a hair curler having adjoining segments oriented in a first rotational direction (such as a hair curler having segments oriented in a right-handed or clockwise direction configured to produce right-handed curls) and a hair curler having adjoining segments oriented in a second rotational direction (such as a hair curler having segments oriented in a left-handed or counter-clockwise direction configured to produce left-handed curls). Advantageously, the arrangement of the adjoining segments 326 and the reversibility of the second flange 306 enables the hair pod 300 to be coupled ubiquitously with hair curlers having right and left-handed rotational directions without requiring separate hair pods with respective right and left-handed rotational directions. Thus, each hair pod 300 is configured to operate with rotationally different hair curlers thereby reducing the number of curling accessories needed by the user and improving the overall hair curling experience.



FIG. 10 shows one exemplary embodiment of a hair curler 8300 configured for use with the hair pods described herein. A person skilled in the art will appreciate that the hair pods can be used with various hair curler devices, and the central opening in the hair pod can be modified to have a shape that corresponds to a shape of the selected hair curler device. Accordingly, the hair curler of FIG. 10 is merely one embodiment. As shown, the hair curler 8300 includes a mating portion 7820 and a shaft 8305. In some embodiments, the hair curler 8300 can be coupled to a hair care appliance, such as a hair dryer, as an attachment. In some embodiments, the hair pods described herein can be configured for use with a standalone hair curler that is not an attachment to a hair care appliance. As shown in FIG. 10, an inlet 8315 can be provided in the mating portion 7820. A fluid flow path can be provided between the inlet 8315 and outlets 8320. The outlets 8320 can be provided between a plurality of adjoining segments 8310 of the hair curler 8300. The adjoining segments 8310 can extend along the central longitudinal axis of the hair curler 8300. The adjoining segments 8310 can be secured between an end cap 8325 and the mating portion 7820. The adjoining segments 8310 can be configured in a first rotational direction (e.g., a right-handed or clockwise direction) or a second rotational direction (e.g., a left-handed or counter-clockwise direction) relative to the central longitudinal axis of the hair curler 8300 so that hair can be curled in multiple rotational directions.


The fluid flow path exiting the outlets 8320 can provide a Coanda effect with respect to hair placed in proximity of the fluid flow and the hair curler 8300. The Coanda effect is the tendency of a fluid flow to emerge from an opening, such as the outlets 8320, and to follow an adjacent surface, such as the surfaces of the adjoining segments 8310 of the shaft 8305. Air from the surroundings can be entrained with the fluid flow exiting the outlets 8320 so that a region of lower pressure is developed adjacent to the surface of the adjoining segments 8310. Hair placed in proximity of the fluid flow path can thus be drawn toward the surface of the adjoining segments 8310 by virtue of the fluid flow existing the outlets 8320 and due to the Coanda effect produced by the fluid flow, thereby wrapping the hair around the shaft 8305. In some embodiments, the hair curler 8300 can include a heater assembly disposed within the shaft 8305. In some embodiments, the hair curler 8300 can include both a fluid flow path and a heater assembly disposed within the shaft 8305.


A base of the hair pod described herein can be slidably received onto the shaft 8305 of the hair curler 8300 as shown in FIG. 11. For example, the base 404 can be slid over the end cap 8325 at the distal end 8330 of the hair curler 8300 and into position at the proximal end 8335 of the hair curler 8300. The base 404 can include a plurality of adjoining segments 410 that extend radially away from the annular collar 414 of the base 404. The plurality of adjoining segments 410 can have a rotational direction R′ corresponding to the rotational direction R of the plurality of adjoining segments 8310 of the hair curler 8300. The rotational direction of the plurality of adjoining segments 8310 can correspond to the rotational direction of the fluid flow provided via the outlets 8320 so as to produce a fluid flow exhibiting the Coanda effect previously described. As shown the segments 8310 of the hair curler 8300 and the segments 410 of the base 404 are configured in a right-handed, clockwise rotational direction such that the generated curls will be right-handed curls.


With the base 404 positioned on the shaft 8305, a user can position a cap of the hair pod described herein onto the end cap 8325. The user can place the shaft 8305 in proximity of their hair at a desired curl location. As air is provided via the fluid flow path exiting outlets 8320, the Coanda effect produced by the fluid flow causes the hair to be drawn toward the shaft 8305 and to wrap around the shaft 8305 in a rotational direction corresponding to the direction of airflow and the rotational configuration of the curler (e.g., the rotational direction of the plurality of segments 8310). The user's hair will be continuously drawn toward the shaft 8305 from the desired curl location such that a substantial length of the user's hair extending from the desired curl location will wrap around the shaft 8305. With the user's hair wrapped around the shaft 8305, the base 404 can be advanced along the shaft 8305 toward the cap affixed to the end cap 8325 to capture the hair encircling the shaft 8305 between the cap and the base 404 (e.g., within the entrapment area of the hair pod). With the base 404 and cap coupled, the user can then remove the hair pod from the shaft 8300 such that the hair pod is retained in or on the user's hair. The user can leave the hair pod attached to their hair for a desired period of time to set the curl. The permanency of the curl can be increased by leaving the hair pod in the user's hair for longer periods of time.


In another embodiment, shown in the images of FIG. 12A-14, the hair pod 100 described in relation to FIGS. 1A-4 is shown coupled to the hair curler 8300. As shown in FIGS. 12A-14, the hair curler 8300 is configured with a right-handed (R) rotational direction. The base 104 can be slid onto the shaft 8305 by passing the end cap 8325 through the central opening 108 such that the base 108 slides along the shaft 8305 from the distal end 8330 of the shaft 8305 to the proximal end 8335 as shown in FIGS. 12A, 13 and 14. Subsequently, the cap 102 can be slid onto the end cap 8325 of the hair curler 8300 such that the end cap 8325 extends into the central opening 106 of the cap 102 and is secured in place via ribs 124 extending radially inward from the cylindrical housing 110 as shown in FIGS. 12A-12B.


As shown in bottom view of FIG. 13, the base 104 includes a plurality of adjoining segments 114 configured on the annular collar 140. The plurality of adjoining segments can include a first set of adjoining segments 154 and a second set of adjoining segments 156 that are interspersed between the first set of segments 154. The first set of adjoining segments 154 are configured to engage with the adjoining segments 8310 of the hair curler 8300 which have a right-handed or clockwise (R) rotational direction. The second set of adjoining segments 156 can be configured for engaging adjoining segments of a hair curler having a left-handed or counter-clockwise rotational direction. Thus, the second set of adjoining segments 156 are not coupled to the segments 8310 since the hair curler 8300 is not configured in a left-handed or clockwise rotational direction. As shown in the close-up view of 14, the segments 8310 mate with the first set of segments 154 to secure the base 104 onto the shaft 8305 of the hair curler 8300 for producing curls having a right-handed or clockwise rotational direction. The segments 8310 do not mate with the second set of adjoining segments 156 since the rotational direction (R) of the segments 8310 correspond to the rotational direction of the first set of adjoining segments 154 and not the rotational direction of the second set of adjoining segments 156.


In use, a user can configure the base 404 and cap 402 of a hair pod 400 onto a hair curler 8300 as shown in FIG. 15A. The base 404 can be slid over the shaft 8305 via the central opening 416 extending through the annular collar 414 of the base 404. The cap 402 can be slid onto the end cap 8235 of the hair curler 8300 via the central opening 412 of the cap 402. With the base 404 and cap 402 coupled to the hair curler 8300 as illustrated in FIG. 15A, a user can curl their hair by activating the device to cause air to flow from the curler, thereby causing the user's hair to be wrapped around the shaft 8305. Once the hair is fully wrapped around the shaft 8305 between the base 404 and the cap 402, the base 404 can be advanced from a first position shown in FIG. 15A, along the shaft 8305 toward the cap 402 until the upper surface 408 of the base 404 engages with the cap 402 in a second position as shown in FIG. 15B. A cross-sectional view of the hair pod 400 is shown in FIG. 16 illustrating the hair H wrapped around the annular collar 414 and retained within the entrapment area 418. Returning to FIG. 15B, with the user's hair retained within the entrapment area 418 defined by the chamber formed between the base 404 and the cap 402, the user can remove the hair pod 400 from the hair curler 8300 by sliding the hair pod 400 over the end cap 8325 of the hair curler 8300 as shown in FIG. 15C. The user can leave the hair pod 400 in place for period of time to set the curl in their hair.


The improved hair pods and styling assemblies described herein produce a number of advantages. For example, the use of multiple configurations sets of adjoining segments defining the central opening of the base allow the hair pod to be used with hair curlers having a right-handed rotational direction and a left-handed rotational direction, thus eliminating the need for hair pods that are specifically configured for right-handed and left-handed rotational directions. The convenient interference or friction fit provided between the base and the cap make the hair pod easier to manipulate to secure hair within the entrapment area of the hair pod. The use of high-friction materials on the cylindrical housing and portions of the shield of the cap improve the retention of hair within the hair pod and increase the retention of the hair pod on a user's hair. As a result of these features, the hair pods and styling assemblies described herein can create tighter and more well-formed curls along an entire length of the user's hair, remain more securely attached to the user's hair, and provided improved handling for easier handling than existing hair curling devices resulting in an overall improved experience for curling hair.
