In the following description, well-known functions or constructions are not described in detail to avoid obscuring this disclosure in unnecessary detail. In addition, directional terms such as top, bottom, side, and similar terms are used to assist in understanding the description and are not intended to limit this disclosure.

With reference to FIGS. 1-5, a disposable personal care apparatus 10 has a unitary structure (e.g., integrally and/or monolithically formed) and may be in the form of a disposable cleansing apparatus including soap for cleaning the hands and/or the body of a user. The disposable personal care apparatus 10 may include a surfactant configured for cleaning skin. The disposable personal care apparatus 10 includes a top surface 10a and a bottom surface 10b.

The disposable personal care apparatus 10 defines a longitudinal axis “L” and includes a main body 12 and a handle 14 connected to the main body 12 by a stem 16.

In aspects, the main body 12 of the disposable personal care apparatus 10 defines a recess 12a that extends from the bottom surface 10b of the disposable personal care apparatus 10 and into the main body 12. In aspects, the main body 12 does not include a recess 12a. The main body 12 includes a first body end 12f and a second body end 12s disposed opposite to the first body end 12f. The main body 12 includes an annular sidewall 12b that tapers inwardly from the bottom surface 10b of the disposable personal care apparatus 10, which is a bottom surface of the main body 12, to a bottom end portion of the stem 16. The main body 12 includes a rounded annular edge 12c that connects the bottom surface 10b to the annular sidewall 12b of the main body 12.

The handle 14 of the disposable personal care apparatus 10 includes an annular sidewall 14a that tapers inwardly from the top surface 10a of the disposable personal care apparatus 10, which is a top surface of the handle 14, to a top end portion of the stem 16. The handle 14 has a first handle end 14f and a second handle end 14s that is disposed opposite to the first handle end 14f and closer to the first body end 12f of the main body 12 than the second body end 12s of the main body 12. The handle 14 includes a rounded annular edge 14b that connects the top surface 10a to the annular sidewall 14a of the handle 14.

The stem 16 of the disposable personal care apparatus 10, which may be part of the handle 14, defines an annular indentation 16a. The stem 16 further includes an upper portion 16b, a lower portion 16c, and an intermediate portion 16d that is disposed between the upper and lower portions 16b, 16c. In aspects, the intermediate portion 16d is narrower than the upper and/or lower portions 16b, 16c.

The annular sidewall 12b of the main body 12, the annular sidewall 14a of the handle 14, and the annular indentation 16a of the stem 16 define an annular cavity 18 about the disposable personal care apparatus 10.

In aspects, the main body 12 supports the handle 14 in an upright position over the main body 12 when the second body end 12s is mounted on a surface such as a counter, table, or shelf (not explicitly shown).

The handle 14 of the disposable personal care apparatus 10 is configured to increase hand or finger/digit (e.g., thumb and/or finger) grip and manipulation of the disposable personal care apparatus 10, particularly when the disposable personal care apparatus 10, or portions thereof, is/are wet and/or when the hand(s) of the user, digit(s) of the user, and/or portions thereof, are wet.

In use, the handle 14 of the disposable personal care apparatus 10 is grasped by the user so that the user can readily move the main body 12 (e.g., the bottom surface 10b of the main body 12) of the disposable personal care apparatus 10 along the user's skin so that the main body 12 of the disposable personal care apparatus 10, or portions thereof, can treat (e.g., cleanse and/or provide one or more therapeutic effects to the user's body, namely, the skin, for instance, by virtue of the one or more materials of the main body 12). As can be appreciated, the main body 12, or portions thereof, may rub off the main body 12 onto the user's skin or other object, for instance, by friction with the user's skin or other object. In aspects, such frictional engagement with the disposable personal care apparatus 10 can create a lather, e.g., a soapy lather, for cleaning, for example, the user's skin or other object. Of course, the disposable personal care apparatus 10 can also be rubbed and/or massaged onto a washcloth (not shown) or the like as desired for passing materials of the disposable personal care apparatus 10 onto the washcloth so that the washcloth can be used to cleanse the user's body or other object.

For instance, the main body 12, the handle 14, and/or the stem 16 may have conical, cylindrical, spherical ellipsoidal, pseudospherical, and/or like configurations. Indeed, in aspects, the disposable personal care apparatus 10, or portions thereof, may have polyhedral configurations such as cuboid, polygonal prism, polygonal pyramid, and/or the like.

Despite the complexities where the predictability of the outcome was low and prior solutions were unsuccessful or went in a different direction, the long and laborious process of conducting a multitude of trials, testing, and evaluations was conducted until the disclosed disposable personal care apparatus configured for increased comfort, gripability, and maneuverability by a user was unexpectedly developed. Notably, such trials, testing, and evaluations were based on, for example, standard protocols, or modified versions of such protocols, established by the American Society for Testing and Materials (e.g., ASTM 5054), and included evaluations of, for example, fracture initiation energy, fracture energy, and rate of wear (e.g., degradation rate). Indeed, through such effort, various metrics were considered for the following purposes:

• • a. improving user sizing of the disposable personal care apparatus for a user's hand and/or digits to promote gripability;
  • b. enabling the disposable personal care apparatus to stand upright on a surface;
  • c. preventing the handle of the disposable personal care apparatus from separating or snapping off the main body/stem of the disposable personal care apparatus;
  • d. ensuring that the main body degrades at the same rate or before the handle of the disclosed disposable personal care apparatus while maintaining the ability to stand upright on a surface; and
  • e. ensuring that the handle remains non-slip and/or easy-to-grip when the handle is dry or wet.

To achieve the above-noted purposes, the disclosed disposable personal care apparatus has various parameters and/or various ranges of parameters (where each disclosed range includes the endpoints and all values between the endpoints) that can be understood with reference to FIGS. 6-6C and the following definitions:

  • “First Length H1” refers to a first length of the disposable personal care apparatus that extends from the top surface of the disposable personal care apparatus (e.g., the top surface of the handle of the disposable personal care apparatus) to a narrowest region of the stem of the disposable personal care apparatus (e.g., the centerline of the stem);
  • “Second Length H2” refers to a second length of the disposable personal care apparatus that extends from the bottom surface of the disposable personal care apparatus (e.g., the bottom surface of the main body of the disposable personal care apparatus) to the narrowest region of the stem of the disposable personal care apparatus (e.g., the centerline of the stem);
  • “Plane E” refers to a vertical plane that intersects an outer surface of the annular sidewall of the handle and an outer surface of the annular sidewall of the main body, and is located such that the minimum distance from where the plane intersects the main body to where the plane intersects the handle is 12 mm (approximating the tip of the pad of an adult finger);
  • “Plane B” refers to a horizontal plane defined by minimum perimeter B and which is perpendicular to plane E; and
  • “Minimum Distance D” refers to a minimum distance between perimeter B and plane E.

Such parameters and/or ranges of parameters include the following:

• • 1. A surface area of the bottom surface of the main body of the disposable personal care apparatus is in the range of 1,425 mm² to 4,375 mm². This feature enables an adult human hand to be adequately and comfortably cleaned with the main body.
  • 2. A surface area of the top surface of the handle of the disposable personal care apparatus is in the range of 325 mm² to 2,050 mm². This feature helps to ensure that the handle has a surface area that comfortably fits within an adult human hand.
  • 3. A first perimeter ratio of the disposable personal care apparatus is defined by Minimum Perimeter B divided by Maximum Perimeter C and has a maximum value of 0.7 and a minimum value of 0.3. This feature helps to ensure that the handle has a surface area that comfortably fits within an adult human hand. This feature also is a contributing feature that ensures the disposable personal care apparatus can stand upright. This feature is also a contributing feature that ensures the main body degrades before the stem, preventing the main body and the handle from separating and/or snapping off.
  • 4. A second perimeter ratio of the disposable personal care apparatus is defined by Maximum Perimeter A divided by Minimum Perimeter B and has a maximum value of 2.9 and a minimum value of 1.05. This feature helps to ensure that the handle has a surface area that comfortably fits within an adult human hand. This feature also is a contributing feature that ensures the disposable personal care apparatus can stand upright. This feature is also a contributing feature that ensures the main body degrades before the stem, preventing the main body and the handle from separating and/or snapping off.
  • 5. A third perimeter ratio of the disposable personal care apparatus is defined by Maximum Perimeter A divided by Maximum Perimeter C and has a maximum value of 1.0 and a minimum value of 0.2. The feature ensures that the handle is the same size or smaller than the main body so that the disposable personal care apparatus can stand upright (e.g., is not top heavy and is not prone to tipping over).
  • 6. A height ratio of the disposable personal care apparatus is defined by First Length H1 divided by Second Length H2 and has a maximum value of 2.1 and a minimum value of 0.3. This feature is one of several features that ensures that the handle does not degrade faster than the main body.
  • 7. A volume ratio of the disposable personal care apparatus is defined by a volume of a first portion of the disposable personal care apparatus that spans across First Length H1 of the disposable personal care apparatus divided by a volume of a second portion of the disposable personal care apparatus that spans across Second Length H2 of the disposable personal care apparatus and has a maximum value of 1.0 and a minimum value of 0.2.

  • 10. A third degradation ratio of the disposable personal care apparatus is defined by a rate of wear of Minimum Perimeter B divided by a rate of wear of a volume across Second Length H2 and has a value that is less than 1.0. This feature ensures that the narrowest portion of the stem (e.g., a central portion of the stem) does not degrade faster than the main body, preventing the main body from separating from the rest of the disposable personal care apparatus due to fracture in and/or degradation of the stem.
  • 11. A non-slip configuration of the disposable personal care apparatus is defined by the Minimum Distance D and has a value that is greater than 1.2 mm. This feature ensures that the handle is easy to grip, especially when wet, such that when the disposable personal care apparatus is held by the handle in one hand and applied to another hand, for example, the disposable personal care apparatus is less likely to slip out of the user's hand. This feature ensures that a cavity space is created on the disposal personal care apparatus that provides a nook for the tip of the user's finger pad of a sufficient size for facilitating gripping and bracing against sidewalls of the stem, handle, and main body.
  • 12. A bending strength of the disposable personal care apparatus can be greater than or equal to 100 newtons in some aspects. The bending strength, which is defined as a maximum force the disposable personal care apparatus can endure at its narrowest section before failure, can range, in some aspects, from 188 to 312 newton, for example. This failure is characterized by the initiation and propagation of a crack throughout the entire cross section of the soap, culminating in its bifurcation. When a sample undergoes bending, two primary parameters dictate its behavior: the material properties (i.e., Young's modulus, yield strength, etc.) and the sample's geometry, particularly its moment of inertia, which strongly influences the article's resistance to bending. The bending strength inherently encompasses the effects of the moment of inertia of the disposable personal care apparatus, a geometry-dependent parameter. The relationship between bending strength (applied force F), bending stress (σ), and the moment of inertia can be broadly represented as σ∝F/I. This quantitative measure of the resistance of the disposable personal care apparatus to bending stress highlights its structural robustness under external loading conditions while also underscoring the influential role played by the unique geometry of the disposable personal care apparatus.
