In some embodiments, the workpiece engagement member includes a flexible tab that is configured to be pushed radially inward by the mouth of the container when the insert is fully received within the mouth. In some embodiments, the flexible tab includes a tooth, a ramp, a spike, or the like configured to extend into the workpiece when the insert is inserted into the mouth. In some embodiments, the outer surface of the insert and an inner surface of the mouth of the container have complementary insert engagement members. The complementary insert engagement members may include a ridge formed on the outer surface of the insert and a recess formed in the inner surface of the mouth. The packaging system can include a cap that is configured to engage an outer surface of the mouth of the container and to form a seal against the insert. In some embodiments, the cap is provided with a gasket that is configured to form the seal against a flange of the insert. In some embodiments, the workpiece is a porous applicator. In some embodiments, the insert has a cylindrical inner surface with a constant inner diameter. In some embodiments, the insert has a tapered inner surface that tapers from a first inner diameter to a second inner diameter, wherein the first inner diameter is greater than an outer diameter of the workpiece and the second inner diameter is less than the outer diameter of the workpiece.
In another aspect, the present disclosure provides cosmetic packages having a container having a mouth and containing a formulation, an applicator being porous and configured to hold the formulation, and an insert configured to receive the applicator and to retain the applicator within the mouth of the container in an axially aligned configuration. The insert has an annular wall with an outer surface that tapers from a first outer diameter proximal a first end thereof to a second outer diameter proximal a second end thereof, the second outer diameter being greater than the first outer diameter, the first end of the insert being configured for insertion into the mouth of the container before the second end.
In some embodiments, the cosmetic package includes a cap configured to engage an outer surface of the mouth of the container and to urge the insert into the mouth. In some embodiments, the cap includes a gasket configured to seal against a flange of the insert when the insert is received within the mouth of the container and the cap is engaged with the outer surface of the mouth. In some embodiments, the applicator extends into the formulation.
The foregoing aspects and many of the attendant advantages of the claimed subject matter will become more readily appreciated by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
The present disclosure provides packaging systems having two or more components that comprise a collet configured to securely hold elements that are highly deformable, for example soft, flexible, and/or porous elements such as cosmetic applicators and porous components created by additive manufacturing.
Packaging system 100 includes a container 102, an insert 104, a workpiece 106, and an optional cap 108, which assemble together in an axial assembly along axis 110. As described below, the container 102 and the insert 104 cooperate to function as a collet that securely holds the workpiece 106. In some embodiments, the container 102, insert 104, and workpiece 106 assemble together as a permanent assembly. In some embodiments, the container 102, insert 104, and workpiece 106 are configured to be at least partially disassembled, e.g., to facilitate recycling or part replacement. The cap 108 is configured to selectively disassemble from the rest of the assembly.
Container 102 contains a reservoir configured to contain a liquid or solid formulation, e.g., a cosmetic formulation. For example, container 102 is configured to contain a formulation that is drawn up by the workpiece 106, e.g., by absorption. In some embodiments, the reservoir is formed integrally with the container 102, however in some embodiments, the reservoir is a separate component that fits within the container 102. As described in greater detail below, container 102 includes a mouth 112 having a shape and size that are configured to receive insert 104 and workpiece 106. In the representative embodiment of
Insert 104 is configured to secure the container 102 to the workpiece 106, as described in greater detail below. As described in more detail below, insert 104 is configured to receive workpiece 106 and to retain it with mouth 112 of the container 102 is an axially aligned configuration along axis 110. In some embodiments, insert 104 is formed from a foam, a natural or synthetic textile, and the like.
Workpiece 106 is configured to draw up and/or hold formulation from the container 102, and also to release the formulation onto a skin portion of a user. In
Cap 108 is configured to couple with container 102 via a container engagement member (threads, in this embodiment) such that it covers and protects workpiece 106. In
In one representative method of use, a user decouples cap 108 from the container 102 in order to expose workpiece 106. Because the workpiece 106 is nested within the mouth 112 of the container 102 and extends into the formulation-containing reservoir therein, the workpiece 106 holds a quantity of the formulation. Holding the container 102, the user applies the formulation to a skin portion by pressing, brushing, rubbing, or otherwise touching workpiece 106 to the skin portion. In another representative method of use, the user removes workpiece 106 from the insert 104 and applies the formulation to a skin portion by pressing, brushing, rubbing, or otherwise touching workpiece 106 to the skin portion.
The features of the packaging system 100 will now be described in detail.
As most clearly shown in
To further secure the insert 104 within the container 102, the insert 104 includes at least one optional insert engagement member 124 formed on the outer surface 118 of the annular wall 114. The insert engagement member 124 has a complementary shape to a corresponding insert engagement member formed on the inner surface of the mouth 112 of the container 102, as described below. In
Proximal to the first end 120, a bottoming shoulder 126 extends radially inward from axis 110 in order to prevent workpiece 106 from falling into the container 102 when assembled. The bottoming shoulder 126 has an annular shape with an inner diameter that is smaller than the inner diameter D3 of the inner surface 116. In some embodiments, the bottoming shoulder 126 has a different inner diameter than in
Proximal to the second end 122, a flange 128 extends radially outward from axis 110. The flange 128 is configured to rest atop the mouth 112 of the container 102 (e.g., to contact a lip of the mouth 112) when the insert 104 is fully engaged in the mouth 112. In addition, the cap 108 has an interior shoulder that is configured to push against the flange 128, in order to ensure correct coupling between the container 102 and the insert 104. Further still, the flange 128 provides a sealing surface, which a gasket of the cap 108 can seal against in order to prevent leakage or loss of the formulation stored in the container 102. This is described in detail with respect to
Insert 104 further includes a workpiece engagement member 130 that projects radially inward from the annular wall 114, such that the workpiece engagement member 130 engages workpiece 106 when it is inserted into insert 104. In
Workpiece 106 has a first portion 138 and a second portion 140. The first portion 138 has an outer diameter D4 that is about the same as the inner diameter D3 of insert 104 (e.g., +1-0.01 inches). In some embodiments in which the inner diameter D3 of the insert 104 tapers, the outer diameter D4 of workpiece 106 also tapers. The second portion 140 has a smaller outer diameter D5 that is configured to extend past the bottoming shoulder 126 of the insert 104. In some embodiments, the second portion 140 is configured to extend into a formulation 136 stored in the container 102. Where the workpiece 106 transitions from the first outer diameter D4 to the second outer diameter D4, it forms a shoulder 142 configured to contact the bottoming shoulder 126 of the workpiece 106 when inserted into the insert 104.
The mouth 112 of container 102 has an inner surface 144 with an inner diameter D6 that is at least as large as the first outer diameter D1 of the insert 104. In some embodiments, D6 is about 0.005 inches to about 0.015 inches greater than D1, e.g., about 0.010 inches. This dimensional relationship facilitates insertion of the insert 104 into the mouth 112. For example, the bottoming shoulder 126 of the insert 104 can be easily inserted into the mouth 112. On the other hand, the inner diameter D6 of the mouth 112 is the same size or even slightly smaller than the second outer diameter D2 of the insert 104. In some embodiments, the inner diameter D6 is about 0.000 inches to about 0.010 inches smaller than the second outer diameter D2 of the insert 104. Thus, as insert 104 is pushed deeper into the mouth 112, the outer surface 118 thereof eventually pushes against the inner surface 144 of the mouth 112. The contact causes the mouth 112 to expand radially outward and the annular wall 114 to contract radially inward. These counteracting forces cause the container 102 and the insert 104 to act as a collet that holds workpiece 106 in place. In some embodiments, one or both of the workpiece 106 or the mouth 112 is slotted to facilitate contraction and expansion, respectively. The inner surface 144 of the mouth 112 also includes an insert engagement member 146 that is complementary to the insert engagement member 124 of the insert 104. The complementary workpiece engagement members are configured to engage one another when the container 102 and the insert 104 are fully coupled together, i.e., when the insert 104 is fully received within the mouth 112. In addition, the mouth 112 includes at least one cap engagement member 148 that is configured to couple with the cap 108. In
As can be seen, the workpiece 106 is received within the insert 104, which is received within the mouth 112 of the container 102 such that all three are securely coupled together. In
To further secure the workpiece 106 and the formulation 136 within the container 102, the packaging system 100 is provided with the optional cap 108 that is configured to engage an outer surface of the mouth 112. In some embodiments, the cap 108 is also configured to assist with assembly of the packaging system 100 by urging the workpiece 106 into the mouth 112 of the container 102. In the representative embodiment of
Together, the container 102, insert 104, workpiece 106, cap 108, and the formulation 136 comprise a cosmetic package that is configured for easy, leak-free use and appealing aesthetics.
