Description

Applicator head for applying cosmetics

Technical Field

Embodiments of the present disclosure generally relate to a method for applying a product including cosmetics, care or medicines to human skin or keratinous fibers, such as hair, eyebrows, nails and/or eyelashes. The product comprises a viscous liquid, semi-solid or powder product.

Background

In the cosmetic industry, applicators such as dip-type applicators or stick applicators are well known. Cosmetic packages typically include an applicator for dispensing a particular cosmetic product contained in the packaging container. Cosmetic applicators typically include a capped stem and applicator head, and are suitable for use with products including viscous cosmetics, mascaras, eyeliners, lip colors, hair gels, wound care, skin care, ophthalmic cosmetics, pharmaceuticals, and the like.

One such applicator is disclosed in U.S. patent No. 10888145B2 for applying a cosmetic product to the skin of a user. The applicator head includes a first applicator member and a second applicator member. The first applicator member is cylindrical, having a cavity extending through the length of the first applicator member. A non-thermally conductive structure is connected within the cavity of the first applicator member.

Another us patent No. 7481591 discloses an applicator comprising a stem and an application surface formed by a plurality of cones. These cones have a certain elasticity and mobility, so that they can massage cosmetics and store wrinkles and uneven skin areas between them.

An applicator head is disclosed in U.S. patent application No. 20200329846A1, which comprises a first application member, a second application member and a locking portion. The first applicator member comprises at least in part a second applicator member, wherein at least a portion of the second applicator member is made of a heat transfer material to transfer heat or cold upon contact with the stratum corneum of the user.

While these applicators are generally satisfactory, there remains a need for an applicator head configured to apply a cosmetic product and capable of providing a cooling or heating sensation to the skin of a user.

Disclosure of Invention

It is an object of the present utility model to provide an applicator head that is capable of providing a cooling or heating sensation to the skin and of providing a larger contact area on the surface being treated.

It is an object of the present utility model to provide an applicator head made at least in part of a heat storage material. The applicator head has a reservoir that stores at least a portion of the heat storage material, thereby preventing the possibility of 360 degree contact of the outer surface of the heat storage material with the skin. Limiting the outer surface of the heat storage material in contact with the skin increases the time to feel the heating or cooling on the skin.

It is a further object of the present disclosure to provide an applicator head having a reservoir for loading product, thereby enabling the applicator head to be used for longer periods of time or to store more product more easily.

Thus, an applicator head for applying a cosmetic or care product is provided. The applicator head is elongated along a longitudinal axis. The applicator head includes a thermally conductive structure and a thermally non-conductive structure. The easily thermally conductive structure is made of a heat storage material such as metal, ceramic, metal alloy or stone. The thermally conductive structure may be used to massage the skin of a user. The thermally conductive structure defines at least one side wall of the applicator head, while the thermally non-conductive structure defines at least one distal surface of the applicator head. The thermally conductive structure has a cavity extending through at least a portion of a length of the thermally conductive structure. At least a portion of the non-thermally conductive structure is received and retained within the cavity of the thermally conductive structure.

According to one aspect of the present disclosure, cosmetic or care products include viscous cosmetics, mascaras, eyebrow powders, lip colors, hair coloring pigments, skin care, eye cosmetics, pharmaceutical products, and the like. An applicator head is secured to the distal end of the stem.

According to another aspect of the present disclosure, the thermally conductive structure includes a proximal portion and a distal portion. The proximal portion is formed as a stem portion configured to be received within a stem lumen of a stem. The distal portion of the thermally conductive structure is configured to be located on the exterior of the stem and formed into a first applicator portion for user access.

According to another aspect of the present disclosure, the first applicator portion of the thermally conductive structure comprises at least two major faces, a front face and a rear face. In addition, the first applicator portion further includes a right side and a left side. The front face includes a proximal surface and a distal surface. The distal surface extends from the distal end of the thermally conductive structure and/or the applicator head toward the front end of the applicator head. The distal surface is an inclined surface extending along at least 50% of the length of the front face. In a preferred embodiment, the distal surface of the front face of the thermally conductive structure is concave and the proximal surface of the front face is convex.

According to another aspect of the present disclosure, the back side of the first applicator portion of the thermally conductive structure provides a large convexity that can be used for massaging. More specifically, the back face of the first applicator portion is curved along the longitudinal axis of the applicator head and in a direction orthogonal to the longitudinal axis of the applicator head.

According to another aspect of the present disclosure, the distal end of the thermally conductive structure is slightly off-centered with respect to a longitudinal axis toward the back of the first applicator portion. However, in various embodiments of the present disclosure, the thermally conductive structure and/or the distal end of the applicator head may or may not be located on the longitudinal axis.

According to another aspect of the utility model, the distal surface of the first applicator portion has a drop shape with an apex formed at its distal end. However, in alternative embodiments, the distal surface of the first applicator portion may have any other desired shape.

According to another aspect of the present disclosure, an opening forming a cavity is defined on a distal surface of the first applicator portion of the thermally conductive structure. In a preferred embodiment, the distal surface is curved and inclined, and the opening extends obliquely relative to the central longitudinal axis of the applicator head.

In various embodiments, the opening may have any desired shape, including spoon-shaped, inverted oval, elliptical, oblong, triangular, cross, square, rectangular, square, triangular, heart-shaped, or irregular.

In various embodiments, the first applicator portion of the thermally conductive structure may include at least one application element adapted to deliver and apply a cosmetic product. In this case, the application element may be a bevel, protrusion, bristles, flocking, ribs, grooves, discs, slits, cuts, holes, dimples, foam or other surface features or surface treatments (e.g., grinding) suitable for combing,/or loading, transporting and applying cosmetics.

According to one embodiment of the present disclosure, the non-readily thermally conductive structure is an insulator made of a group of materials consisting of plastic, wood, rubber, sintered or porous materials and/or combinations thereof.

According to another aspect of the present disclosure, a non-thermally conductive structure includes an elongated stem portion and a second applicator portion. When the non-thermally conductive structure is received within the cavity of the thermally conductive structure, the second applicator portion protrudes or extends from the opening of the first applicator portion of the thermally conductive structure and a major portion of the elongate stem is received within the cavity of the thermally conductive structure.

According to one aspect of the present disclosure, the second applicator portion is connected (e.g., fixedly) to the elongated stem or integrally formed.

According to one embodiment of the present disclosure, the length of the elongated stem of the non-thermally conductive structure is greater than the length of the cavity of the thermally conductive structure, and therefore the elongated stem extends from the proximal end of the cavity of the thermally conductive structure.

According to one embodiment of the present disclosure, the second applicator portion extends along a plane. In a preferred embodiment, the plane is a curved plane. The plane of the second applicator portion enables it to closely match the plane of the distal surface of the first applicator portion and provides a better fit after assembly. In a preferred embodiment, in particular, the second applicator portion provides an upper surface and a bottom surface, wherein the upper surface is a continuous concave curved surface and the bottom surface is a convex curved surface. The bottom surface is designed and dimensioned to closely contact the distal surface of the first applicator portion of the thermally conductive structure. The second applicator portion is in the shape of a drop of similar size to the distal surface. The second applicator portion is shaped and sized to fit over and cover the distal surface of the first applicator portion. An elongate stem extends downwardly from the bottom surface. The upper surface of the second applicator portion of the non-thermally conductive structure is configured to apply/spread the product to the skin of the user.

According to another aspect of the utility model, in use, when the applicator head is removed from the container, the wiper portion scrapes the applicator head so as to retain an optimal amount of product on the upper surface of the second applicator portion so that the user can transfer the product to the keratinous surface using the second applicator portion of the non-readily thermally conductive structure. Thus, the upper surface of the second applicator portion forms a reservoir. This reservoir serves as a reservoir for the cosmetic product. A large amount of cosmetic product may be contained in the reservoir and may be applied to the skin or keratinous substrate of the user.

According to another aspect of this embodiment, at least a portion of the upper surface of the second applicator portion includes a flocked portion. However, in alternative embodiments of the present disclosure, it may not be concentrated on the upper surface of the second applicator portion.

In various embodiments, the upper surface of the second applicator portion may include protrusions, ribs, grooves, other surface features, or surface treatments (e.g., grinding) suitable for loading, transporting, and applying cosmetics.

According to another aspect of the present embodiment, the elongated stem portion of the non-thermally conductive structure may be retained within the cavity of the thermally conductive structure by a locking means known in the art, such as a j-lock, threaded engagement, interference engagement, magnetic engagement, or the like. In a preferred embodiment, the thermally easily conductive structure and the thermally non-easily conductive structure are secured to each other by a snap-fit joint. In particular, the thermally conductive structure may include a raised ring on an inner surface thereof, and the elongated stem portion of the thermally non-conductive structure may include a recessed ring and an annular flange adjacent the recessed ring. When the applicator head is assembled, the elongated stem portion of the non-thermally-conductive structure is inserted into the cavity of the thermally-conductive structure through the opening of the thermally-conductive structure, and the male ring of the thermally-conductive structure is mounted into the corresponding female ring of the non-thermally-conductive structure, thereby limiting further insertion of the non-thermally-conductive structure with respect to the thermally-conductive structure. Furthermore, the annular flange of the non-thermally conductive structure is locked to the collar, making it difficult for the non-thermally conductive structure to face the opening.

In an alternative embodiment, the male ring may be on a non-thermally conductive structure, in which case the female ring is on a thermally conductive structure.

According to one aspect of the present disclosure, complementary locating features are provided on the thermally conductive structure and the thermally non-conductive structure to locate the thermally non-conductive structure in a predetermined desired position relative to the thermally conductive structure. Preferably, the non-readily thermally conductive structure is oriented such that the apex of the non-readily thermally conductive structure always coincides with the apex of the readily thermally conductive structure. In a preferred embodiment, the elongate stem has a rectangular portion located adjacent the second applicator portion, the rectangular portion corresponding to the cavity adjacent the opening, which aids in locating and preventing rotation of the second applicator portion relative to the thermally conductive structure.

According to one aspect of the present disclosure, a cosmetic package associated with an applicator head is provided and includes a container for containing a product and an applicator assembly. The applicator assembly includes an applicator head, a stem, and a cap. The cap of the applicator assembly is threaded and can be screwed onto the threads on the neck of the container. An applicator head is retained at the distal end of the stem for applying the product; covering the proximal end of the shaft.

In general, the terms "distal" and "proximal" are used herein to refer to the distal end being the side/end facing the interior of the storage container, and the proximal end being the side/end facing the opening of the container.

In addition, the distal end of the stem includes an internal longitudinal stem cavity for receiving and retaining the applicator head.

Placed in the neck of the container is a wiper for wiping excess product from the applicator assembly.

Furthermore, the applicator head of the applicator assembly may be used to apply products including cosmetic or care products. The cosmetic or care product comprises viscous cosmetic, mascara, eyebrow powder, lip gloss, hair color, skin care, under-eye cosmetic, medicine, etc.

The applicator head and stem may be mounted together by friction fit, snap fit, adhesive, crimping, magnetic engagement, or the like. In a preferred embodiment, the applicator head and the stem are mounted together by a snap fit joint. The shank of the thermally conductive structure includes at least one annular protrusion and the inner surface of the shank cavity includes a corresponding annular recess. When the stem portion of the applicator head is inserted into the internal longitudinal cavity of the stem, the at least one annular projection is snapped into the corresponding annular groove.

A second embodiment according to the present disclosure provides an applicator head that is similar to the applicator head of the first embodiment, except that the shape differs between the two embodiments.

Similar to the first embodiment, the thermally conductive structure of the second embodiment forms a portion of the side wall of the applicator head, while the thermally non-conductive structure of the second embodiment is located at the distal surface of the applicator head. The distal portion of the thermally conductive structure is a first applicator portion that is located outside of the wand for use by a user. Further, the first applicator portion of the thermally conductive structure includes a front face, a back face, a right side face, and a left side face. The front face includes a proximal surface and a distal surface. The proximal surface is convex. The distal surface is an inclined plane extending along at least 40% of the length of the first applicator portion.

According to an aspect of the second embodiment, the back face is lip-shaped along the length of the applicator head. More specifically, the back surface includes a proximal protrusion, followed by a medial concavity and a distal convexity. The distal surface of the first applicator portion has a drop shape with a vertex at the distal end.

In a second embodiment, similar to the first embodiment, the cavity passes through at least a portion of the thermally conductive structure with at least a portion of the thermally non-conductive structure contained therein. The opening of the cavity is located on the inclined and smooth distal surface of the first applicator portion. The non-thermally conductive structure is comprised of an elongated stem portion and a second applicator portion. The second applicator portion extends from an opening of the cavity on the distal surface of the first applicator portion when the non-thermally conductive structure is placed within the cavity of the thermally conductive structure. The second applicator portion has an upper surface and a bottom surface. Unlike the first embodiment, the second applicator portion in the second embodiment is planar, rather than concave. Both the upper and bottom surfaces of the second wiper portion are planar.

The applicator head according to the third embodiment of the present utility model is circular and oval. The applicator head also includes one or more through slots. These one or more channels help optimize product application, control product release, enhance flexibility, and contribute to overall aesthetics.

Similar to the other embodiments, the applicator head of the third embodiment includes an easily thermally conductive structure forming part of the applicator head sidewall portion and a non-easily thermally conductive structure mated to the distal surface of the applicator head. The proximal portion of the thermally conductive structure is a stem configured to be mounted in a cavity of a rod. The distal portion of the thermally conductive structure is a first applicator portion located on the exterior of the stem. The first applicator portion includes at least one sidewall and a distal surface. The distal surface is an inclined planar surface. The distal surface extends along at least 50% of the length of the first applicator portion. The distal surface of the first applicator portion has an oval shape.

According to an aspect of the third embodiment, the second applicator portion has a protrusion that aligns with the distal surface of the first applicator portion to form an elliptical and circular applicator head. The second applicator portion includes one or more through slots extending transversely to the length of the applicator head. Wherein the size or shape of one or more of the through slots may vary. However, it is within the scope of the present disclosure that one or more through slots may have the same size or shape.

It will be understood that the foregoing is only illustrative of the principles of the disclosure and that various modifications can be made by those skilled in the art without departing from the scope and spirit of the disclosure. For example, the shape and/or size of the various components may be different than those shown herein. As another example, the materials used for the various components may be different from those specifically mentioned herein.

Detailed Description

Like reference numerals designate like or corresponding parts throughout the several views. While illustrative embodiments of the present disclosure have been described and illustrated above, it should be understood that these are exemplary embodiments of the present disclosure and are not to be considered as limiting. Additions, deletions, substitutions, and other modifications of the present utility model may be made without departing from the spirit and scope of the present disclosure. Accordingly, the present disclosure is not limited by the following description.

In this specification, the terms "comprising," "including," "composition," and the like are intended to always denote a set of objects, not limited to those specifically recited.

Fig. 1 shows a longitudinal cross-sectional view of a cosmetic package 100 including an applicator head 10 according to a preferred embodiment of the present disclosure. Associated with applicator head 10 is a cosmetic package 100 including a container 20 for holding a cosmetic product (not shown) and an applicator assembly 30. The applicator assembly 30 includes an applicator head 10, a stem 40 and a cap 50. The cap 50 of the applicator assembly 30 has threads 52 that can be secured to the threads 52 on the neck 22 of the container 20. The applicator head 10 is held at the distal end of the stem 40 for applying the product and the cap 50 is located at the proximal end of the stem 40.

In general, the terms "distal" and "proximal" as used herein shall mean that the distal side/end is the side/end facing the interior of the storage container 20, and the proximal side/end is the side/end opening to the container 20.

In addition, the distal end of the stem 40 includes an internal longitudinal stem cavity 42 for receiving and retaining the applicator head 10. Inserted into the neck 22 of the container 20 is a wiper 60 for wiping excess product from the applicator assembly 30.

Furthermore, the applicator head 10 of the applicator assembly 30 may be used to apply a cosmetic or care product, including a cosmetic or care product. The cosmetic or care product comprises viscous cosmetic, mascara, eyebrow powder, lip gloss, hair color, skin care, under-eye cosmetic, medicine, etc.

Fig. 2 shows a perspective view of the applicator head 10 according to a preferred embodiment of the present disclosure. The applicator head 10 may be used to apply products including cosmetic or care products. The cosmetic or care product comprises viscous cosmetic, mascara, eyebrow powder, lip gloss, hair color, skin care, under-eye cosmetic, medicine, etc. The applicator head 10 is intended to be held at the distal end of the stem 40.

As shown in fig. 2, the applicator head 10 extends in the direction of the longitudinal axis X. The applicator head 10 comprises an easily thermally conductive structure 2 and a non-easily thermally conductive structure 12. The thermally conductive structure 2 defines at least a portion of a side wall of the applicator head 10, while the thermally non-conductive structure 12 defines a portion of a distal surface of the applicator head 10. The thermally conductive structure 2 is configured to receive and accommodate at least a portion of the thermally non-conductive structure 12.

According to the exemplary embodiment shown in fig. 1 and 6, the thermally easily conductive structure 2 comprises a proximal portion 2a and a distal portion 2b. The proximal portion 2a is formed as a stem 3 and is configured to be received within a stem lumen 42 of the stem 40. The distal end portion 2b of the thermally conductive structure is located outside the stem 40 and is formed into a first applicator portion 4 that is available to the user.

Referring to fig. 1-5, the first applicator portion 4 of the thermally easily conductive structure 2 comprises at least two main faces, namely a front face 4a and a rear face 4b. The first applicator portion 4 further comprises a right side 4c and a left side 4d. As shown in fig. 6, the front face 4a includes a proximal end surface 5a and a distal end surface 5b. Referring to fig. 5, the distal surface 5b extends from the distal end 11 of the thermally conductive structure 2 and/or the applicator head 10 to the front side of the applicator head 10 when the thermally conductive structure 2 is seen in a side view thereof. The distal surface 5b is an inclined surface extending along at least 50% of the length of the front face 4a of the first applicator portion 4 of the thermally easily conductive structure 2. The distal surface 5b of the front face 4a of the thermally conductive structure 2 is concave, while the proximal surface 5a of the front face 4a is convex.

Referring to fig. 4 and 7, the back surface 4b of the first applicator portion 4 of the thermally easily conductive structure 2 provides a large convexity for massaging. The back face 4b of the first applicator portion 4 is curved along the longitudinal X-axis of the applicator head 10 and in a direction orthogonal to the longitudinal X-axis X of the applicator head 10, see the figure. 7 and 8.

Furthermore, as shown in fig. 7, the distal end 11 of the thermally easily conductive structure 2 is slightly off-centered with respect to the longitudinal X-axis towards the rear face 4b of the first applicator portion 4. However, in various embodiments (not shown), the thermally conductive structure 2 and/or the distal end 11 of the applicator head 10 may or may not be located at the longitudinal X-axis.

Referring to fig. 6 and 7, the distal surface 5b of the first applicator portion 4 has a drop shape forming an apex at its distal end 11. However, in alternative embodiments, the distal surface 5b of the first applicator portion 4 may have any other desired shape.

According to one aspect of this embodiment, as shown in fig. 6 and 7, the thermally easily conductive structure 2 has an extended cavity 6. At least a portion of the non-thermally conductive structure 12 is received within the cavity 6 of the thermally conductive structure 2.

As shown in fig. 6, an opening 7 with a cavity 6 is defined in the distal surface 5b of the first applicator portion 4 of the thermally conductive structure 2. As the distal surface 5b is curved and inclined, the opening 7 also extends obliquely with respect to the central longitudinal X-axis of the applicator head 10. In various embodiments, the opening 7 may have any desired shape, including spoon-shaped, inverted oval, elliptical, oblong, triangular, cross, rectangular, square, triangular, or irregular.

According to one aspect of this embodiment, as shown in fig. 3-5, the thermally easily conductive structure 2 is made of a heat storage material such as metal, ceramic, metal alloy, or stone. Thus, the heat-conductive structure 2 can be used for massaging the skin of a user.

However, in a variant embodiment (not shown), the first applicator portion 4 of the heat-conductive structure 2 may comprise at least one application element suitable for delivering and applying the cosmetic product. In this case, the applicator element may be a bevel, protrusion, bristle, flocking, rib, groove, disk, slit, cut, hole, dimple, foam, or other surface feature or surface treatment (e.g., grinding) suitable for combing, loading, transporting, or applying cosmetics.

According to one embodiment of the present disclosure, the diameter of the shank 3 is smaller than the largest diameter of the distal end 2b of the thermally easily conductive structure 2.

Referring to fig. 6 and 7, the non-thermally conductive structure 12 includes an elongated stem portion 13 and a second applicator portion 14. When the non-thermally conductive structure 12 is received within the cavity 6 of the thermally conductive structure 2, the second applicator portion 14 protrudes or extends from the opening 7 of the cavity 6 at the distal end surface 5b of the first applicator portion 4 of the thermally conductive structure 2, and a substantial portion of the elongate stem portion 13 is received within the cavity 6 of the thermally conductive structure 2. The second applicator portion 14 is (e.g., fixedly) connected to the elongate stem portion 13 or integrally formed therewith.

According to the exemplary embodiment shown in fig. 7, the length of the elongated stem portion 13 of the non-thermally conductive structure 12 is greater than the length of the cavity 6 of the thermally conductive structure 2, and thus the elongated stem portion 13 extends from the proximal end of the cavity 6 of the thermally conductive structure 2.

Referring to fig. 6 and 7, the second applicator portion 14 has an upper surface 14a and a lower surface 14b. In an exemplary embodiment, the upper surface 14a has a gradual and continuous concave-convex curved surface, and the lower surface 14b has a similarly shaped concave-convex curved surface. The second applicator portion 14 extends along a plane that enables the second applicator portion 14 to closely match the surface of the distal end surface 5b of the first applicator portion 4. The lower surface 14b is designed and dimensioned to be in close contact with the distal surface 5b of the first applicator portion 4 of the thermally easily conductive structure 2. As shown, the second applicator portion 14 is drop-shaped with a similar size to the distal surface 5b. The second applicator portion 14 is shaped and sized to fit over and cover the distal surface 5b of the first applicator portion 4. An elongated stem 13 extends downwardly from the lower surface 14b.

The upper surface 14a of the second applicator portion 14 of the non-thermally conductive structure 12 is configured to apply/spread the product to the skin of the user. In use, as the applicator head 10 is withdrawn from the container 20, the wiper 60 wipes across the applicator head 10, leaving an optimal amount of product on the upper surface 14a of the second applicator portion 14 so that a user can transfer the product to the skin surface of a person using the second applicator portion 14 of the non-thermally conductive structure 12. Thus, the upper surface 14a of the second applicator portion 14 forms a reservoir. This reservoir serves as a reservoir for the cosmetic product. A large amount of cosmetic product may be contained in the reservoir and may be applied to the skin or keratinous substrate of the user.

According to another aspect of this embodiment, as shown in fig. 5 and 6, at least a portion of the upper surface 14a of the second applicator portion 14 includes a pile group 19. However, in another embodiment, as shown in fig. 7, the upper surface 14a of the second applicator portion 14 cannot be gathered.

In various embodiments (not shown), the upper surface 14a of the second applicator portion 14 may include protrusions, ribs, grooves, other surface features, or surface treatments (e.g., grinding) suitable for loading, transporting, and applying cosmetics. The second applicator portion 14 may be made of a material capable of retaining a fluid or semi-solid cosmetic product, which may be, for example, a material such as a sponge material, a foam material, a woven material or a nonwoven material, or any porous material including sintered materials.

According to another aspect of the present embodiment, the elongated stem portion 13 of the non-thermally conductive structure 12 may be retained within the cavity 6 of the thermally conductive structure 2 by locking means known in the art, such as a J-lock, threaded engagement, interference engagement, magnetic engagement, or the like. In the exemplary embodiment shown in fig. 1 and 7. The thermally easily conductive structure 2 and the thermally non-easily conductive structure 12 are secured to each other by a snap fit. Referring to fig. 7 and 9, the thermally easily conductive structure 2 comprises a collar 15 on its inner surface, and the elongated stem portion 13 of the thermally non-easily conductive structure 12 comprises a female collar 16 and an annular flange 17 adjacent to said female collar 16. When the applicator head 10 is assembled, the elongated stem portion 13 of the non-thermally conductive structure 12 is inserted into the cavity 6 of the thermally conductive structure 2 through the distal end surface 5b of the thermally conductive structure 2, and the male ring 15 of the thermally conductive structure 2 is quickly inserted into the corresponding female ring 16 of the non-thermally conductive structure 12, thereby limiting further insertion of the non-thermally conductive structure 12 relative to the thermally conductive structure 2. Furthermore, the annular flange 17 of the non-thermally conductive structure 12 locks onto the collar 15, making it difficult for the non-thermally conductive structure 12 to face the opening 7.

In an alternative embodiment, the male ring 15 may be on the non-thermally conductive structure 12, in which case the female ring 16 is on the thermally conductive structure 2.

According to one aspect of the present disclosure, complementary orientation features are provided on the elongated stem portion 13 of the thermally conductive structure 2 and the thermally non-conductive structure 12 to place the thermally non-conductive structure 12 in a predetermined desired position relative to the thermally conductive structure 2. Preferably, the non-readily thermally conductive structure 12 is oriented such that the apex of the non-readily thermally conductive structure 12 always coincides with the apex of the readily thermally conductive structure 2. Referring to fig. 6, 8 and 9, the elongate stem portion 13 has a rectangular portion 13a adjacent the second applicator portion 14 corresponding to the rectangular portion of the cavity 6 adjacent the opening 7 which helps locate and prevent rotation of the second applicator portion 14 relative to the thermally conductive structure 2.

The applicator head 10 and the stem 40 may be mounted together by friction fit, snap fit, adhesive, crimping, magnetic engagement, or the like. In the exemplary embodiment shown in fig. 1, the applicator head 10 and the stem 40 are mounted together by a snap-fit connection. The shank portion 2a of the heat-conductive structure 2 comprises at least one annular projection 2c and the inner surface of the shank cavity 42 comprises a corresponding annular recess 43.
