Patent Application
20240108118
The present disclosure generally relates to cosmetic, hair care, body care, and/or skincare products and, more particularly, to systems and approaches for containing and retaining such products.
Cosmetic, hair care, body care, and/or skincare products may be provided in a number of different containers, and may be applied using a number of varying approaches. As an example, a lipstick or lip balm product may be in the form of an elongated tube, cylinder, square, rectangular, and/or diamond prism, among other shapes that is disposed in a protective container. Such containers may allow the cosmetic substance to selectively advance to an extended position relative to the container to be applied by the user. The cosmetic substance may be a generally solid, yet relatively soft, molded composition that may be inserted into a cavity of a retaining cup. In the event the container is inadvertently dropped or otherwise jostled, the cosmetic substance may become damaged, broken, or otherwise detached from the retaining cup. In some examples, the retaining cup (or other features of the container) may include discrete retention members in the form of hooks, nodules, or similar components that may be urged into the cosmetic substance in an attempt to prevent or otherwise limit movement of the cosmetic substance relative to the cup and the container during these inadvertent drops or bumps. However, these features may create localized stress points that may ultimately deform or otherwise damage the cosmetic substance.
Accordingly, there is a need for improved accessories having improved functionalities.
Examples within the scope of the present disclosure are directed to a cosmetic product container and retention mechanism that may include a cup for retaining a cosmetic substance. The cup includes a cup body having a first end, a second end, and an inner sidewall forming a cup cavity and a stepped retention member disposed on the inner sidewall of the cup body and extending into the cup cavity. The stepped retention member has a first width value extending around the periphery of the inner sidewall.
In some examples, the stepped retention member includes a plurality of angled protrusions extending inwardly into the cup cavity. In some of these examples, each of the angled protrusions may include a side surface and a lower surface. The side surface may define a side surface area value and the lower surface may define a lower surface area value. The ratio of the side surface area value to the lower surface area value may be between approximately 4:1 and approximately 12:1.
In some examples, the cup may further include a second retention member disposed on the inner sidewall of the cup body and extending into the cup cavity. The second retention member may have a second width value extending around the periphery of the inner sidewall. In these examples, the first width value may be greater than the second width value. In some of these forms, the second retention member includes an elongated notch having a first end, a second end, and an undercut formed at the second end thereof. The cup may further include a cup retention member disposed on an outer surface of the cup body. The cup retention member may be aligned with the second retention member.
In an approach, the cup may include a floor member positioned at or near the stepped retention member.
In accordance with a second aspect, a cosmetic product container includes an outer container having first and second ends and defining a container cavity, a cup adapted to be at least partially disposed within the container cavity, and a cosmetic substance having first and second ends and an elongated body therebetween. The cup includes a cup body having first and second ends and an inner sidewall forming a cup cavity and a stepped retention member disposed on the inner sidewall of the cup body and extending into the cup cavity. The stepped retention member has a first width value extending around the periphery of the inner sidewall. At least a portion of the elongated body of the cosmetic substance is disposed within the cup cavity.
The above needs are at least partially met through provision of one, more than one, or any combination of the cosmetic product containers and retention mechanisms described in the following detailed description, particularly when studied in conjunction with the drawings, wherein:
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions and/or relative positioning of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of various examples. Also, common but well-understood elements that are useful or necessary in a commercially feasible examples are often not depicted in order to facilitate a less obstructed view of these various examples. It will further be appreciated that certain actions and/or steps may be described or depicted in a particular order of occurrence while those skilled in the art will understand that such specificity with respect to sequence is not actually required. It will also be understood that the terms and expressions used herein have the ordinary technical meaning as is accorded to such terms and expressions by persons skilled in the technical field as set forth above except where different specific meanings have otherwise been set forth herein.
Generally speaking, pursuant to these various approaches, cosmetic product containers and retention mechanisms are provided that adequately retain a cosmetic substance during use as well as in the event of inadvertent drops and/or bumps. The approaches described herein provide firm retention of the cosmetic substance while reducing or eliminating potentially harmful stress regions. As such, the systems described herein may be used to contain and retain a multitude of cosmetic substances having varying degrees of material softness.
Turning to the Figures, a cosmetic product 100 is provided for containing and applying a cosmetic substance 101. The cosmetic product 100 includes a base 102, a track 108, an inner body 112, a shell 116, and a retention mechanism 120. In the illustrated examples, the cosmetic substance 101 is in the form of a lipstick or lip balm product. It is to be appreciated that the cosmetic substance 101 may be any type of cosmetic, hair care, body care, and/or skincare product that may be applied to a user. Other examples are possible. In some of these examples, the cosmetic substance 101 may include strong or otherwise aggressive chemicals and/or ingredients such as, for example, volatiles. The cosmetic substance 101 includes a first end 101a, a second end 101b, and an elongated body 101c extending therebetween along a longitudinal axis (“A”). Further, the cosmetic substance 101 defines an outer cross-sectional dimension (“DO”). In the illustrated examples, the outer cross-sectional dimension DO is in the form of an outer diameter or circumference. However, other examples are possible.
Generally speaking, the base 102 at least partially retains components of the cosmetic product 100 in a base cavity 103. The base cavity 103 defines a ledge 104 formed on an inner surface, and further includes a securement mechanism 105 formed on an outer surface thereof. The securement mechanism 105 may be used to engage a portion of a cap (not illustrated) to conceal the cosmetic substance 101 for storage purposes. Any number of suitable securement mechanisms 105 may be used such as, for example, a snap-fit coupling, a friction-fit coupling, a threaded connection, and the like. Other examples are possible.
The track 108 is at least partially disposed within the base cavity 103 and includes a first end 108a and a second end 108b and defines a channel 109. The inner body (which, in some examples, may be referred to as an outer container) 112 is at least partially disposed within the base cavity 103 and includes an inner surface 113 and a notch 114. The shell 116 is also at least partially disposed within the base cavity 103 and is provided to prevent a user from observing these components. The shell 116 includes a lip 117 that engages a portion of the inner body 112 to restrict movement in a direction along the longitudinal axis A. It is to be appreciated that any of the base 102, the track 108, the inner body 112, and/or the shell 116 may include any number of additional features and/or components to assist in use of the cosmetic product 100, but for the sake of brevity, such features and/or components will not be discussed in substantial detail herein.
The retention mechanism 120 is provided to securely retain the cosmetic substance 101. The retention mechanism 120 includes a cup 122 having a cup body 124. The cup body 124 includes a first end 124a, a second end 124b, an inner sidewall 124c, and a cup cavity 125. Generally speaking, the cosmetic substance 101 is at least partially disposed within the cup cavity 125. The cup body 124 further includes a cup retention member 130. The cup body 124 may be formed from any number of desired materials.
With reference to
The cup body 124 further includes any number of stepped retention members 134 disposed on the inner sidewall 124c. Each stepped retention member 134 includes any number of angled protrusions or ridges 136 that extend into the inner cavity 125 in a stepped pattern. It is to be appreciated that while each of the illustrated stepped retention members 134 includes four angled protrusions 136, fewer or more than four angled protrusions 136 may be used to improve retention of the cosmetic substance 101.
Each angled protrusion 136 includes a side surface 136a and a lower surface 136b that cooperate to form a step or undercut (see
As previously noted, the lower surface 136b of each angled protrusion 136 forms an undercut region. The lower surface 136b has a relatively shallow depth or shortened profile, and as such, does not extend into the cup cavity 125 as much or as far as previous designs. Such an arrangement is in contrast to existing systems that protrude or extend further into the cup cavity in an attempt to provide a greater retaining force with the cosmetic substance. In the present application, the lower surface 136b is dimensioned to be relatively shallow and have a less aggressive undercut depth to allow cosmetic substances 101 formed from softer compositions to better flow into these regions below the lower surface 136b, whereas existing systems may have resulted in a void area that does not include any cosmetic substance. Such a void area in previously-used systems could result in a lessened surface area contact between the cup and the cosmetic substance. Further, cosmetic substances 101 formed from softer compositions may become structurally weakened by more aggressive undercut depths, and as such, the angled protrusions 136 described in the present disclosure may better maintain the structural integrity of the cosmetic substance 101.
Each side surface 136a of the angled protrusion 136 defines a side surface area value. Each side surface 136a may be generally concave in that it has a curvature that is similar to or the same as the curvature of the curved inner sidewall 124c. Further, each lower surface 136b of the angled protrusion 136 defines a lower surface area value. In some examples, the ratio of the side surface area value to the side surface area value is between approximately 4:1 and approximately 12:1. Other examples are possible.
In some examples, the cup body 124 may additionally include a floor member 132 positioned at or near the first end 124a thereof. This floor member 132 may provide additional support for the first end 101a of the cosmetic substance 101. In some examples, the stepped retention member 134 may extend to or terminate at the floor member 132. In other examples, a gap (not illustrated) may be defined between a lowermost angled protrusion 136 of the stepped retention member 134 and the floor member 132. Further, in some examples, the floor member 132 may include a number of through bores or channels 132a.
To assemble the cosmetic product 100, the cup body 124 is coupled with the inner body 112 to retain the cup body 124 in a relatively fixed position with respect to the longitudinal axis A. However, in other examples, the cup body 124 may not be coupled with the inner body 112 at this point. The first end 101a of the cosmetic substance 101 is then inserted into the cup cavity 125. Because the outer cross-sectional dimension DO of the cosmetic substance 101 is similar to an inner cross-sectional dimension of the inner sidewall 124c, such insertion of the cosmetic substance 101 causes a portion of the elongated body 101c of the cosmetic substance 101 to contact the inner sidewall 124c in addition to each stepped retention member 134. Inserting the cosmetic substance 101 into the cup cavity 125 causes each angled protrusion 136 to gently insert into a portion of the cosmetic substance 101. As previously noted, the broad ridges of the side surfaces 13a of the angled protrusions 136 create increased surface area, and thus frictional, contact with the cosmetic substance 101, and the cosmetic substance 101 may flow into the area below the lower surface 136b of each angled protrusion 136, thereby creating additional surface area contact with the lower surfaces 136b. These factors, combined with the multiple ridge steps allow for better hold on outer surface # of 101
Accordingly, the stepped retention member or members 134 apply a gentle retaining force against the elongated body 101c of the cosmetic substance 101. It is to be appreciated that any number of characteristics such as, for example, any number of desired dimensions of the stepped retention member 134 and/or material characteristics of the cosmetic substance 101 may be modified to generate a relatively gentle or relatively firm retention force against the cosmetic substance 101 without causing excessive damage or deformation along the elongated body 101c due to the significant surface area contact between the angled protrusions 136 and the elongated body 101c. In some approaches, material properties of the cosmetic substance 101 may dictate the quantity and dimensions of each stepped retention member 134 to ensure the cosmetic substance 101 is not damaged or otherwise deformed during insertion or use.
With reference to
In some examples, the retention mechanism 120 may include any number of optional features. For example, as illustrated in
Upon inserting the cosmetic substance 101 into the cup cavity 125, the cosmetic substance 101 may additionally at least partially encapsulate the second retention members 140, whereupon the second retention members 140 may restrict or otherwise limit rotation of the cosmetic substance 101 with respect to the cup cavity 125 about the longitudinal axis A. In other examples, the cosmetic substance 101 may be inserted into the cup cavity 125 via other approaches such as, for example, any number of backfilling techniques. In any of these filling techniques, the retention members 140 restrict or otherwise limit rotation of the cosmetic substance 101.
It is to be appreciated that while the second retention members 140 are illustrated in the Figures, these second retention members 140 are merely optional features and are not required for the cup 122 to retain the cosmetic substance 101. Further, it is to be appreciated that while the second retention members 140 are oriented in a generally parallel direction with respect to the longitudinal axis A, in some arrangements, any number of the second retention members 140 may be oriented in a non-parallel direction with respect to the longitudinal axis A (e.g., any number of second retention members 140 may form a spiral or helix about the inner sidewall 124c of the cup body 124). Other arrangements are possible.
It is also to be appreciated that the retention mechanism 120 may be provided in any number of varying shapes and/or configurations. As non-limiting alternative examples,
In the example retention mechanism 220 illustrated in
As previously noted, the retention mechanisms described herein may include any number of stepped surfaces or angled protrusions. In the example retention mechanism 320 illustrated in
So configured, the retention mechanism and product described herein securely retains the cosmetic substance without damaging portions thereof. The retention mechanism advantageously increases surface area in shear contact with the cosmetic substance 101 compared with traditional designs, thereby increasing friction to assist with retaining the cosmetic substance 101 within the cup cavity 125 during use, drops, and/or other unintended movements. Further, the presently-described retention mechanism and product do not include additional stress concentration areas that may otherwise result in the cosmetic substance being fractured, stretched, or otherwise damaged during unintentional movements. The retention mechanisms described herein may also provide additional stability to protect the cosmetic substance in the event of a drop or bump event. More specifically, the retention mechanism may maintain alignment of the cosmetic substance so that it does not become misaligned after a drop or bump. Such misalignment may cause the cosmetic substance to contact interior portions of the product during upward application, which in turn may damage or smear the cosmetic substance.
