Swimming cap

Abstract

The present disclosure relates to a swimming cap having a wall that may include a surface having a higher coefficient of friction (e.g., higher than a conventional swimming cap and / or higher than other surfaces of the swimming cap). In some embodiments, a surface finish may be positioned at various locations of the inner face of the swimming cap, and in some examples, the surface finish is positioned near an edge of the swimming cap (e.g., a tip edge forming a perimeter around a head opening of the swimming cap). In some examples, a band extending around the edge may be associated with a thicker material wall, which may increase the elastic modulus and fit tightness of the swimming cap. The swimming cap may include various materials, and in some examples, the swimming cap includes silicone.

Description

Background Art

[0001] Swim caps are typically worn during swimming competitions, training, or exercise activities, such as to affect hydrodynamics. A swim cap can include a latex composition, and in some instances, the swim cap is constructed from a relatively flat mold or die, such as using a relatively wide and flat mold core.

[0022] The detailed description relates to a swim cap that fits more securely to an athlete's head. For example, the inward-facing surface of the swim cap can include a surface finish configured to be less likely to slip off the athlete's head. In some examples, the surface finish can be associated with a higher coefficient of friction (e.g., higher than a conventional swim cap and / or higher than other surfaces of the swim cap). The surface finish can be located at various positions on the inward-facing surface, and in some examples, the surface finish is located near the edge of the swim cap (e.g., the end edge forming the perimeter of the head opening around the swim cap). For example, the surface finish can be at one or more positions on a strap that extends around the edge of the swim cap. In some examples, the strap that extends around the edge can be associated with a thicker material wall, which can increase the elastic modulus and fit tightness of the swim cap.

[0023] Some conventional swim caps may be prone to slipping inadvertently from an athlete's head (e.g., due to hydrodynamic drag). Additionally, some conventional swim caps may pose challenges for athletes with more hair on their heads (e.g., longer or thicker hair), such as discomfort and / or failure to provide a large enough and / or shaped volume to accommodate the hair. Further, some conventional swim caps may not be well-suited to conform to a variety of different head shapes. Additionally, some materials used to form the swim cap may be prone to tearing (or otherwise failing) during manufacture or use. Moreover, some materials (e.g., latex) may be more likely to cause allergies, which can cause irritation and discomfort to the wearer.

[0024] Thus, contrary to conventional swim caps, the subject matter of the present disclosure is less likely to slip (e.g., based on a surface finish with a higher coefficient of friction and / or a thicker band with a higher modulus of elasticity). In some instances, other portions of the swim cap (e.g., other than the band) may include thinner walls, which may be associated with a lower modulus of elasticity to allow for easier stretching to accommodate hair and / or various head shapes. In at least some instances, the swim cap can be used as a base swim cap configured to be worn under a second swim cap (e.g., under an outer swim cap), and the swim cap can include one or more surface finishes on an outer surface configured to improve the fit and operability with the outer swim cap.

[0025] Some examples of the present disclosure relate to the subject matter of manufacturing a swimming cap that includes a swimming cap having a domed wall. In some cases, manufacturing a swimming cap having a domed wall may involve different equipment and / or processes compared to a swimming cap having a more planar or flat wall. In some examples, a mold for forming a swimming cap having a domed wall may include a core (e.g., a domed core) and a cavity (e.g., a two-piece cavity that can be selectively opened and closed around the core). Additionally, a surface finish associated with the swimming cap can be formed by configuring the surface of the cavity and / or the core. For example, if a higher gloss surface is desired, the surface of the core and / or the cavity can be configured to have a smoother, higher gloss surface (e.g., compared to a matte surface of a swimming cap that can be formed via a rougher surface of the cavity or the core). Further, if a textured surface is desired, the surface of the cavity and / or the core can be textured or include a negative relief of the texture. In some examples, a mold (e.g., having a domed core) can be used to manufacture a silicone swimming cap (e.g., by injection molding), including a desired surface finish (e.g., a higher grip surface on the inner surface). Contrary to conventional methods, a mold having a domed core can allow a manufacturing process that is less likely to tear the swimming cap (e.g., during manufacturing). Additionally, a silicone-based swimming cap can have a lower allergenicity (e.g., compared to latex in some cases). In some examples, a silicone-based swimming cap can provide a desired amount of elasticity (e.g., for conforming to the shape of the wearer's head, hair, etc.), while also providing durability and other desired characteristics.

[0026] The terms "a", "an", "the", "at least one", and "one or more" may be used interchangeably to indicate the presence of at least one of an item. When using such terms, there may be more than one such item, unless the context clearly indicates otherwise. Unless clearly or expressly indicated otherwise in the context (including the appended claims), all numerical values of parameters (e.g., amounts or conditions) in this specification should be understood to be modified in all instances by the term "about", whether or not the term "about" actually appears before the numerical value. "About" indicates that the stated numerical value allows some slight imprecision (numerically close to the exact value; close to or reasonably close to the value; almost). If the imprecision provided by "about" is not otherwise understood in the art in this ordinary meaning, then "about" as used herein indicates at least the variations that may result from the ordinary methods of measuring and using such parameters. Additionally, the disclosure of a range should be understood to specifically disclose all values within the range and further divided ranges. If the definition of "about" is necessary for interpreting the terms of the present disclosure, then "about" refers to + / - 10% of a given value.

[0027] The terms "comprising", "including", and "having" are inclusive and thus specify the presence of the stated material, feature, step, operation, element, or component, but do not preclude the presence or addition of one or more other materials, features, steps, operations, elements, or components. When possible, the order of steps, processes, and operations may be changed and additional or alternative steps may be employed. As used in this specification, the term "or" includes any and all combinations of the associated listed items. The term "any one of" shall be understood to include any possible combination of the recited items, including "any one of" the recited items. The term "any one of" shall be understood to include any possible combination of the recited claims of the appended claims, including "any one of" the recited claims.

[0028] The phrases "formed from" and "formed of" are also intended to be inclusive throughout this disclosure and the appended claims and specify the presence of the stated material, feature, step, operation, element, or component, but do not preclude the presence or addition of one or more other materials, features, steps, operations, elements, or components, unless otherwise indicated.

[0029] For consistency and convenience, directional adjectives may be employed throughout the detailed description corresponding to the illustrated examples. One of ordinary skill in the art will recognize that terms such as "above", "below", "upward", "downward", "top", "bottom", etc. may be used descriptively with respect to the figures and do not denote a limitation on the scope of the embodiments of the invention described in this specification and further defined by the claims.

[0030] In some instances, the description may refer to the modulus of elasticity and the coefficient of friction. One or more techniques known to one of ordinary skill in the art may be used to measure these properties based on the context of this disclosure.

[0031] In some instances, the modulus of elasticity includes the resistance to elastic deformation (e.g., non-permanently) when a stress or force is applied. A lower modulus of elasticity (e.g., relative to the modulus of elasticity between two articles) indicates a lower resistance to elastic deformation when subjected to a given stress or force, and a higher modulus of elasticity (e.g., relative to the modulus of elasticity between two articles) indicates a higher resistance to elastic deformation when subjected to a given stress or force. In some instances, the modulus of elasticity of a region or portion of a swim cap may be determined by attaching the region or portion of the swim cap to a gripping device (e.g., via a clamp), applying a tensile force in given units, and determining the degree of stretch (e.g., percentage elongation relative to a rest state). By subjecting each region to the same tensile force and comparing the degree of stretch, the moduli of elasticity of different regions may be compared.

[0032] In some instances, the coefficient of friction is a value that quantifies the resistance to movement between two objects, such as the surface of a swim cap and human skin. Static friction can describe the amount of force required to move a swim cap relative to human skin when the swim cap is initially stationary relative to the human skin. Kinetic friction can describe the amount of force required to move the swim cap relative to human skin when the swim cap is already in motion relative to the human skin. A lower coefficient of friction, or static or kinetic friction (e.g., relative to the friction between two items), indicates that less force is required to move the swim cap relative to human skin. In some instances, a higher coefficient of friction, or static or kinetic friction (between the swim cap and human skin), can translate to a swim cap that is less likely to slip off the wearer. In some instances, the coefficient of friction is a value that quantifies the resistance to movement between the surface of the swim cap (e.g., the outward-facing surface) and water.

[0033] As used herein, the terms “outer” and “inner” are relative terms such that an outer layer is positioned external to one or more inner layers, and an inner layer is positioned internal to one or more outer layers. When used with respect to a support garment, the term “innermost-facing surface” means the layer that is positioned closest to the wearer's body surface compared to other layers of the support garment. When used with respect to a support garment, the term “outermost-facing surface” means the layer that is positioned closest to the external environment relative to other layers of the support garment. Positional terms such as “medial” and “lateral” are used in their customary anatomical sense.

[0034] As used in the present disclosure, “dome-shaped” can indicate a structure or wall that is dome-shaped in part. For example, the inner surface can include a concave profile, and the outer surface can include a convex profile. In some instances, a dome-shaped wall can include at least some portions that are relatively symmetric (e.g., similar profiles or convexities or concavities), and the wall can also be asymmetric in some respects and still be considered dome-shaped. A dome-shaped wall is not necessarily hemispherical, but it can be hemispherical. In some instances, the profile of the concave first surface can correspond to an anatomical region of the wearer. Various aspects are described below with reference to the drawings. However, the examples of the present disclosure are not limited to those illustrated in the drawings or explicitly described below. It should also be understood that the drawings are not necessarily drawn to scale, and in some cases, details may have been omitted (e.g., for ease of illustration).

[0035] Now refer to Figure 1 , Figure 1Depicts an exemplary swim cap 110 that includes a wall 111 (e.g., a domed wall) that at least partially encloses a volume 112 for receiving a portion of a wearer's head. The wall 111 may compositionally include various elastic materials such as silicone or other elastomeric materials, hypoallergenic materials. As used herein, an elastic material may be elastically stretched (e.g., under tension) from its original length and substantially return to its original length (e.g., when the tension is removed).

[0036] In addition, the swim cap 110 includes an edge 114 (e.g., the terminal edge of the domed wall 111) that forms a perimeter around an opening 116 for putting on and taking off the swim cap 110. The swim cap 110 also includes an inner surface 118 that faces the head when the swim cap 110 is worn and an outer surface 120 that faces away from the head when the swim cap 110 is worn. In some instances, the swim cap 110 may include a band 122 that extends circumferentially along the edge 114 and around the periphery of the opening 116, and the band 122 may include a width 124 that extends from the edge 114 to an opposing point 126 that is spaced apart from the edge 114. In some instances, the opposing point 126 may be associated with a change in a characteristic associated with the band 122 to a characteristic associated with another portion of the swim cap 110 that is located further from the edge 114. That is, the position associated with the opposing point 126 may be based on a point (e.g., located at a point) at which a characteristic associated with the cap transitions from a characteristic associated with the band 122 to a different set of characteristics. In some instances, one or more characteristics that may be changed near the opposing point 126 may include wall thickness (e.g., the thickness of the wall 111) and surface finish on the inner surface 118 and / or the outer surface 120.

[0037] In at least some examples of the present disclosure, the inner surface 118 can include a surface finish configured to be less prone to slipping from an athlete's head. As used herein, a surface finish can refer to a surface texture, a material deposit applied to the surface, or a combination thereof. The surface texture can include surface reliefs of positive material and negative spaces molded into the surface during the manufacture of the surface. The surface texture also includes surface reliefs formed via additive manufacturing processes and / or subtractive manufacturing processes. In some examples, the surface finish can be associated with a higher coefficient of friction relative to human skin (e.g., higher than a conventional swim cap and / or higher than other surfaces of the swim cap). The surface finish can be positioned at various locations on the inner surface 118, and in some examples, the surface finish is positioned near the edge 114 of the swim cap 110. For example, the surface finish can be at one or more locations along the band 122. The surface finish can include various characteristics. In some examples, the surface finish can include a plurality of raised protrusions protruding from the inner surface 118 toward the volume 112 and / or a series of grooves or voids or interstitial spaces forming a pattern of positive relief material portions. The protrusions and positive relief material portions can include nodules, bumps, ribs, ridges, polygonal shapes, or other shapes. For example, the enlarged view 128 depicts a plurality of raised nodules 130.

[0038] In some examples, the surface finish on the inner surface 118 can include other or different characteristics. For example, referring to Figure 2 , the swim cap 210 is depicted as having at least some characteristics similar to the swim cap 110, and for the sake of brevity, those same characteristics are not described again (but it should be understood that the same description can apply to the swim cap 210). According to some examples, the swim cap 210 can include one or more surface finishes associated with the inner surface 218. For example, the enlarged view 228 depicts an example surface finish that can include a combination of a matte portion 230 and a high gloss portion 232.

[0039] In an example, the combination of the matte portion 230 and the high-gloss portion 232 can contribute to or result in a higher coefficient of friction (e.g., between a portion of a swim cap and human skin). In at least some examples, the terms “matte,” “low gloss,” and “high gloss” (and “lower gloss” and “higher gloss”) refer to the relative degree between the portion 230 and the portion 232, or more generally, the relative degree between surface finishes or different aspects of a surface finish. A surface finish with “low gloss” is more matte or duller, while a surface finish with “high gloss” is less matte or less dull or has a higher gloss. For example, the portion 230 can be more matte and have a lower gloss or not a very high gloss compared to the portion 232, and the portion 232 can have a higher gloss or a glossier finish and be less matte compared to the portion 230. In some examples, the higher-gloss surface of the swim cap can be associated with a higher coefficient of friction compared to a lower-gloss surface that can be associated with a lower coefficient of friction relative to human skin. For example, Figure 2 the portion 232 in

[0040] In at least some examples, specular reflection can be measured using a glossmeter to determine the gloss of a surface by projecting a light beam onto the surface at a fixed intensity and angle and measuring the amount of reflected light at an equal but opposite angle. In some examples, by comparing the relative amount of reflected light measured using a glossmeter, a surface can have a lower gloss or a higher gloss compared to another surface. A surface associated with a higher amount of reflected light (compared to a different surface) can be described as having a higher gloss or being less matte, while a different surface associated with a lower amount of reflected light can be described as having a lower gloss or being more matte or duller.

[0041] In at least some examples, the matte portion 230 and the high-gloss portion can include repeating patterns. In at least some examples, the matte portion 230 can include a pattern of n-sided polygon shapes spaced apart by recessed gap spaces of the high-gloss portion 232. In some examples, the high-gloss portion 232 can include a pattern of n-sided polygon shapes spaced apart by recessed gap spaces of the matte portion 230.

[0042] In Figure 2In [the example], the surface finish includes a pattern of triangular high-gloss portions 232 separated by recessed gap spaces of the matte portions 230. These are merely examples, and the pattern can include a variety of different shapes. In some examples, these recessed gap spaces have a strip form (e.g., relatively long and narrow, where the length is longer than the width). In some examples, the strip form can be relatively straight. In some examples, the strip form can be wavy. In some examples, the recessed gap spaces can have an irregular form (e.g., where the protrusions are not necessarily aligned in rows or patterns). In some examples, the raised protrusions can be organized in a repeating pattern, or in other examples, these raised protrusions can be organized irregularly. In some examples, the surface finish includes a plurality of high-gloss surfaces and low-gloss surfaces that are not raised or protruding.

[0043] Now refer to Figure 3A and Figure 3B , an example swim cap 310 is depicted, and the swim cap 310 is illustrated as being turned inside out, such that the inner surface 318 (e.g., configured to face the wearer) faces outward, and the outer surface 320 (e.g., configured to face away from the wearer) faces inward. In an example, the swim cap 310 can include at least some features similar to the swim cap 110 and / or the swim cap 210, and for the sake of brevity, those same features are not described again (but it should be understood that the same description can apply to the swim cap 310).

[0044] In an example, the swim cap 310 can include a band 324 that extends around the edge 314. In at least some examples, the band 324 can be associated with a thicker material wall. For example, the band 324 can include a first thickness 334 that is thicker than other portions of the swim cap 310 (compared to the band 324), and these other portions (such as those associated with a second thickness 336) are farther from the edge 314. In some examples, the first thickness 334 can be in the range of about 1.5 mm to about 2.5 mm; or be about 2.0 mm. In some examples, the second thickness 336 can be in the range of about 0.7 mm to about 1.5 mm.

[0045] In some examples, the band 324 and / or the swim cap 310 can include a tapered portion 338, and the thickness of the tapered portion 338 tapers as the wall of the swim cap 310 transitions from the first thickness 334 to the second thickness 336. In at least some examples, based on the thicker wall, the band 324 can be associated with a higher modulus of elasticity, which can help to fit more firmly on the wearer's head and can reduce the likelihood of the swim cap 310 slipping inadvertently (e.g., due to hydrodynamic drag).

[0046] In some instances, at least a portion of the inner surface 318 includes a matte surface finish, such as in the top or apex portion of the cap. In an instance, the matte finish (compared to a higher gloss surface) is less likely to snag hair when the cap is put on or taken off and / or when the cap is displaced on the wearer during use. In other instances, at least a portion of the inner surface includes a higher gloss surface finish, such as where additional grip is desired (e.g., near the band 324). In some instances, the swim cap 310 may also include on the inner surface 318 one or more zones along the band 324 associated with a higher coefficient of friction (e.g., higher than a conventional swim cap and / or higher than other surfaces of the swim cap). For example, the band 324 may include a first surface finish similar to Figure 1 the surface finish in (e.g., Figure 3C ), a second surface finish similar to Figure 2 the surface finish in (e.g., Figure 3D ) or a combination thereof. Thus, the subject matter of the present disclosure is less likely to slip compared to a conventional swim cap (e.g., based on the surface finish with a higher coefficient of friction and / or the thicker band 324 with a higher modulus of elasticity).

[0047] The band 324 may include a width 325 that extends from the edge 314 to an opposite point 326 spaced from the edge 314 (e.g., Figure 3B ). In some instances, the opposite point 326 may be associated with a change in a property associated with the band 324 to a property associated with other portions of the swim cap 310 that are more remotely located from the edge 314. That is, the position associated with the opposite point 326 may be based on a point (e.g., located at a point) at which a property associated with the cap 310 transitions from a property associated with the band 324 to a different set of properties, such as wall thickness, surface finish, etc. In an instance, the band 324 may include a width dimension 325 in the range from about 1.0 cm to about 6 cm, or from about 2 cm to about 5 cm, or from about 3 cm to about 4 cm (e.g., from the edge 314 to the point 326). In some instances, the width dimension may include a dimension as a ratio of the total height 308 of the cap 310, which may be defined by the distance 308 between the edge 314 of the swim cap 310 and the apex 309 of the top of the swim cap 310. For example, in some instances, the ratio of the width 325 to the total height 308 may be in the range from about 1:3 to about 1:8. In some instances, the ratio of the width 325 to the height 308 is about 1:5.

[0048] In some instances, the width 325 can vary at different locations around the cap 310. For example, the front portion of the cap 310 can be associated with a first width 325, the side portions of the cap 310 can be associated with a second width 325, and the rear portion of the cap 310 can be associated with a third width. In an instance, at least one of the second width and the third width can be different from the first width. For example, the first width can be less than or greater than at least one of the second width and the third width.

[0049] As indicated above, the band 324 can be associated with a thickness 334 (e.g., wall thickness). In some instances, the band 324 can be associated with multiple wall thicknesses, such as in the case where the surface finish includes a pattern of protrusions. For example, referring Figure 3E and Figure 3F , cross-sectional views taken along the Figure 3D reference line 3-3 of different embodiments are depicted.

[0050] Referring Figure 3E , the band 324e can be associated with protrusions (e.g., 332e) and the gap spaces (e.g., 330e) between these protrusions 332e. In some instances, the band 324e can be associated with a first thickness 342 directly adjacent to the edge 314e. In some instances, at least some of the protrusions 332e can also be associated with the first thickness 342. Additionally, the gap spaces 330e can be associated with a second thickness 344. In some instances, when the gap spaces 330e extend away from the edge 314e, these gap spaces 330e can include a consistent depth.

[0051] In some instances, referring Figure 3F , the band 324f can be associated with protrusions 332f and the gap spaces 330f between these protrusions 332f. In some instances, the band 324f can be associated with a first thickness 346 directly adjacent to the edge 314f. In some instances, at least some of the protrusions 332f can also be associated with the first thickness 346. Additionally, the gap spaces 330f can include various depths (e.g., relative to the face 318), which can depend on the location of the gap spaces within the band 324f. In at least some instances, the gap spaces 330f can gradually transition from a shallower depth closer to the edge 314f to a deeper depth farther from the edge 314f, and then gradually transition from the deeper depth to a shallower depth near the tapered portion 338. In this way, the wall thickness associated with the gap spaces 330f can transition (e.g., gradually or stepwise) from a larger thickness 348 closer to the edge 314f to a smaller thickness 350 in the middle region of the band 324f, and back to a larger thickness 352 closer to the tapered portion 338f.

[0052] In other words, the distance between the outer 320f and the recessed gap space 330f is smaller in the second region 356 than in the first region 354 or the third region 358. Regions 354 and 358 may be similar such that the shallower recessed gap space 330f and the thicker walls 348 and 352 may contribute to a greater modulus of elasticity, which may help to fit more securely on the wearer's head. Region 356 (compared to regions 354 and 358) with a deeper recessed gap space and thinner walls may help to reduce the modulus of elasticity such that the wearer can more easily stretch the strap 324f over their head, hair, goggles, or other accessories. In some instances, the strap 324f may be associated with multiple modulus of elasticity values such that some regions of the strap 324f stretch more or more securely than other regions of the strap 324f, which may help to fit securely and be able to stretch the cap over the head. In at least some instances, the terms "shallow" and "deep", "thinner" and "thicker" refer to the relative degree between regions 354, 356, and 358, or more generally, the relative degree between surface finishes or different regions of a surface finish.

[0053] In some instances, other portions of the swim cap (e.g., other than the strap 324) may include thinner walls (e.g., walls associated with a second thickness 336 that is less than a first thickness 334), which may be associated with a lower modulus of elasticity (e.g., lower than the modulus associated with the thicker strap 324). Thus, the thinner walls with a lower modulus of elasticity may stretch more easily to accommodate hair (e.g., long hair, thick hair, braided hair, etc.) and / or various head shapes. In some instances, the region associated with the wearer's hair (the more upper region of the cap 310 relative to the edge 314, such as a higher position at the top or apex) has thinner walls and produces a lower modulus of elasticity to allow stretching to accommodate the hair. In some instances, the region with thinner walls may be positioned along the midline of the cap to align with hair that has been pulled back prior to putting on the cap. In some instances, the region closer to the strap (other than the strap) has thicker walls (compared to the walls associated with the more upper region of the swim cap 310) and produces a higher modulus of elasticity to avoid the cap slipping (compared to the lower modulus of elasticity of the more upper region of the swim cap 310).

[0054] In at least some instances, swim caps 110, 210, and / or 310 can be used as a base swim cap configured to be worn under a second swim cap (e.g., under an outer swim cap - not shown), and the swim cap can include one or more surface finishes on an outer surface configured to improve fit and operability with the outer swim cap. In some instances, swim caps 110, 210, and / or 310 used as a base swim cap can interlock with a second outer swim cap through interaction of the surface finish of the base swim cap with the surface finish of the second swim cap. In some instances, swim caps 110, 210, and / or 310 can be used as a second outer swim cap and can interlock with a base swim cap through interaction of the surface finish of the base cap with the surface finish of the second swim cap.

[0055] Now referring to Figures 4A to 4C , an example swim cap 410 is depicted, and the swim cap 410 includes an outer surface 420 (e.g., configured to face away from the wearer). In an instance, the swim cap 410 can include at least some characteristics similar to swim cap 110, swim cap 210, and / or swim cap 310, and for the sake of brevity, those same characteristics are not described again (but it should be understood that the same description can apply to swim cap 410). In an instance, the outer surface 420 of the swim cap 410 can include one or more zones having different surface finishes. For example, the swim cap 410 is depicted in Figure 4A , Figure 4B and Figure 4C as having one or more first regions 450 associated with a first surface finish and one or more second regions 452 associated with a second surface finish that is different from the first surface finish. The first surface finish and the second surface finish can vary in one or more respects. For example, the first surface finish and the second surface finish can vary in smoothness or roughness associated with the respective surface (e.g., one surface finish may have a higher gloss than another). In some instances, the surface finish can include a plurality of protrusions (e.g., 120, portions 450, portions 452, etc.) protruding from the outer surface, and the plurality of protrusions can take the form of nodules, bumps, ribs, ridges, or raised polygons. Additionally, one surface finish can include a higher gloss than another surface finish, and the other surface finish can include a lower gloss finish or a matte finish. In an instance, different surface finishes can be associated with various operations of the swim cap 410. For example, in some cases, the surface finish can be configured to affect hydrodynamics (e.g., by reducing drag, such as by affecting the boundary layer). In some instances, the outer surface (e.g., 120, portions 450, portions 452, etc.) surface finish is associated with a lower coefficient of friction (e.g., lower than a conventional swim cap and / or lower than other surfaces of the swim cap). In some instances, the surface finish can be configured to help hold swimming goggles.

[0056] Referring now to Figures 5A to 5F , an example swim cap 510 is depicted in an inside-out view, and the swim cap 510 includes an inner surface 530 (e.g., configured to face the wearer). In an example, the swim cap 510 may include at least some of the same features as the swim caps 110, 210, 310, and / or 410, and for the sake of brevity, those same features are not described again (but it should be understood that the same description may apply to the swim cap 510). In an example, the inner surface 530 of the swim cap 510 may include one or more surface finish regions 524a-524c associated with a band 524 having different features. For example, in some examples, the regions 524a-524c are associated with different surface areas including corresponding surface finishes. For example, the size or amount of the surface area may be based on the height of the region covered with the corresponding surface finish (e.g., where a first region 524a is thicker / taller / wider than a third region 524c, and the third region 524c is thicker / taller / wider than a second region 524b).

[0057] For example, the swim cap 510 is depicted in Figure 5A , Figure 5B and Figure 5C as having one or more widths associated with the band 524 in different views, where the widths are associated with portions of the band 524 including a textured surface finish. In some examples, the textured surface finish is associated with a higher coefficient of friction, which may translate to a more "grippy" feel (for the wearer). Figure 5A A side view of an example swim cap 510 is depicted, and the side view includes a first region 524a and a second region 524b, the first region 524a including a width 524e( Figure 5E ), and the second region 524b corresponding to a width 524d( Figure 5D ). In an example, the first width 524e is wider or larger than the second width 524d. In some examples, the first width 524e is associated with the wearer's forehead region and provides a coefficient of friction (e.g., grip) that facilitates holding the cap on the wearer (e.g., by not slipping off the forehead). In other examples, the first width 524e may be associated with other regions of the wearer. In some examples, the second width 524d is associated with the wearer's side head region (e.g., the region associated with the ears and / or the side of the head and / or the goggle strap) and provides a lower coefficient of friction (compared to the first width 524e). In some cases, the lower grip along the side (based on the second region 524b) may improve the wearer's ear comfort. In some examples, the coefficient of friction is the same between the first width 524e and the second width 524d. In some examples, the first width 524e tapers to the second width 524d, and in other examples, there is no taper between the two widths.

[0058] Figure 5B Depicts a front view of an exemplary swim cap 510 associated with a first width 524e and a second width 524d, the first width 524e being associated with the wearer's forehead region and configured to provide a surface with a higher coefficient of friction to avoid slipping from the wearer's forehead, and the second width 524d being associated with the wearer's lateral head region. In other instances, the first width 524e and the second width 524d may be associated with other regions of the wearer. In some instances, the first width 524e is thicker or larger than the second width 524d. In some instances, the first width 524e tapers into the second width 524d, and in other instances, there is no taper between the widths.

[0059] Figure 5C Depicts a rear view of an exemplary swim cap 510, including a third region 524c of the band 524, and associated with a second width 524d and a third width 524f( Figure 5F ) where the third width 524f is wider than the second width 524d. In some instances, the third region 524c and the third width 524f are associated with the wearer's neck region and provide a degree of surface friction conducive to avoiding slipping from the wearer's neck region. In some instances, the third width 524f may be the same width as the first width 524e, or it may be a different width. In some instances, between the first width 524e, the second width 524d, and the third width 524f, these characteristics are the same or similar. In some instances, the third width 524f tapers into the second width 524d, and in other instances, there is no taper between the widths.

[0060] As indicated above, the band 524 may have various surface finishes associated with the first region 524a, the second region 524b, and the third region 524c. In some instances, the band 524 may be associated with a plurality of wall thicknesses corresponding to the first region 524a, the second region 524b, and the third region 524c, such as in the case where the surface finish includes a pattern of protrusions. For example, referring to Figures 5D to 5F , depicts cross-sectional views taken along the corresponding cross-reference lines in Figures 5D to 5F of different embodiments.

[0061] Referring to Figure 5D , the second width 524d associated with the second region 524b may be associated with protrusions (such as 532d) and gap spaces (such as 530d). In some instances, at least a portion of the second width 524d associated with the second region 524b is associated with Figure 5Dassociated with the cross-section shown. In some instances, the second width 524d associated with the second region 524b has a shallower gap space 530d (compared to the gap space in Figure 5E and Figure 5F ), and corresponds to the first wall thickness 550d. In some instances, the second width 524d associated with the second region 524b is associated with multiple wall thicknesses. In some instances, the first wall thickness 550d is similar to the wall thicknesses in other regions.

[0062] Referring Figure 5E , the first width 524e associated with the first region 524a has a deeper gap space 530e (compared to the gap space in Figure 5D ), and corresponds to the second wall thickness 550e. In some instances, the first wall thickness 550d is thinner than the second wall thickness 550e, and in other instances, the first wall thickness 550d and the second wall thickness 550e are the same. In some instances, the first width 524e associated with the first region 524a has a gap space 530e of the same depth (compared to the gap space in Figure 5D and Figure 5F ), and in other instances, the first region 524a has a gap space 530e of different depths (compared to the gap space in Figure 5D and Figure 5F ). In some instances, the first width 524e associated with the first region 524a is associated with multiple wall thicknesses.

[0063] Referring Figure 5F , the third width 524f associated with the third region 524c has a deeper gap space 530f (compared to the gap space in Figure 5D ), and corresponds to the third wall thickness 550f. In some instances, the first wall thickness 550d, the second wall thickness 550e, and the third wall thickness 550f are the same, and in other instances, the third wall thickness 550f is different from the second wall thickness 550e and the first wall thickness 550d or a combination thereof. For example, the third wall thickness 550f can be thinner than the second wall thickness 550e. In some instances, the third width 524f associated with the third region 524c is associated with multiple wall thicknesses.

[0064] Now referring Figure 6, depicts an exemplary swim cap 600 having a wall configured to form around a human head. In an example, the swim cap 600 can include at least some of the same features as swim caps 110, 210, 310, 410, and / or 510, and for the sake of brevity, those same features are not described again (but it should be understood that the same description can apply to the swim cap 600). In some examples, the distal edge 614 of the swim cap 600 forms a contour around the forehead, ears, or neck. For example, the swim cap 600 includes a concave contour along the distal edge 614. In other examples, the contour can be convex. In some examples, the portion of the swim cap 600 associated with accommodating the user's hair can be oval-shaped so that the hair can fit easily inside. For example, the swim cap 600 can be shaped in a shape corresponding to a human head, where the hair is accommodated at the upper or apex region of the head. In other examples, the swim cap is dome-shaped and may not have a contour around the forehead, ears, and neck.

[0065] Various methods can be used to construct the swim caps (e.g., swim caps 110, 210, 310, 510, and 600). Referring to Figure 7 , in at least some examples, a mold 710 having a cavity 712 and a core 714 (e.g., a dome-shaped core) can be used to mold the swim cap. For example, the cavity 712 can include a two-part cavity having a first part 712a and a second part 712b, and the first part 712a and the second part 712b can move together (e.g., slide together such that a pin on the second part 712b inserts into a recess on the first part 712a) to enclose the space between the core 714 and the cavity 712. Then, a material (e.g., silicone) can be injected into the space between the core 714 and the closed cavity 712 to form the swim cap.

[0066] In an example, a swim cap can be molded with an inside-out orientation such that an outside surface (e.g., 120, portion 450, portion 452, etc.) is oriented towards the core 714 and an inside surface (e.g., 118, 218, 318, and 530) is oriented towards the cavity 712. Accordingly, the surface of the core 714 can be configured to create one or more surface finishes on the outside surface of the swim cap (e.g., 120, portion 450, portion 452, etc.), and the surface of the cavity 712 can be configured to create one or more surface finishes on the inside surface of the swim cap (e.g., 118, 218, 318, and 530). For example, in cases where a high-gloss surface finish associated with the face of the swim cap is desired, the corresponding surface of the core and / or cavity can include a high-gloss surface (e.g., a smoother surface). In some examples, in cases where a matte finish is desired, the cavity and / or core can include a rougher surface. In some examples, in cases where one or more finishes associated with the face of the swim cap are desired, the cavity and / or core can include both a region with a high-gloss surface and a region with a less glossy surface. For example, the core 714 can include regions corresponding to region 450 and region 452 and configured to create a desired surface finish (e.g., a higher gloss creates a smoother surface and a rougher texture creates a more matte finish).

[0067] In some examples, a band 716 extending around the lower edge of the cavity 712 (e.g., along the lower edges of both the first portion 712a and the second portion 712b) can be configured to create one or more surface finishes (e.g., 130, 230, 232, etc.) on the band of the swim cap (e.g., 124, 324, 524). In some examples, the band 716 can include a recessed cavity configured to form a protrusion (e.g., a raised nodule 130), and / or the band 716 can include a pattern of smoother and rougher surfaces to form corresponding high-gloss and matte surface finishes (e.g., corresponding to 230 and 232). Additionally, in some examples, the band 716 can be recessed into the surface of the cavity 712 such that a swim cap band (e.g., 324) molded via the corresponding cavity band 716 can include a first wall thickness (e.g., 334) that is thicker than other walls of the swim cap. That is, when the cavity sides are closed, the space between the band 716 and the core 714 can be wider than the space between other regions of the cavity 712 and the core 714.
