Dispenser with thermal storage tip
View Patent ↗A dispenser includes a thermal storage tip and a housing having a reservoir for containing a product, such as a cosmetics product or a medicinal product. The thermal storage tip comprises a material that is capable of storing and retaining thermal energy during application of the product.
1. A dispenser comprising:
a housing having a reservoir for containing a product;
a thermal storage tip coupled to the housing, the thermal storage tip comprising metal or ceramic and having an application face for applying the product to a surface, the thermal storage tip having a volume of at least about 300 millimeters 3 and at most about 700 millimeters 3 ; and
an insert disposed in the thermal storage tip, the insert defining a product delivery passageway between the reservoir and an aperture in the application face.
2. The dispenser of claim 1 , wherein the insert is disposed in the thermal storage tip substantially flush with the application face of the thermal storage tip.
3. The dispenser of claim 1 , wherein the insert is disposed in the thermal storage tip and is truncated such that the insert is recessed relative to the application face of the thermal storage tip.
4. The dispenser of claim 1 , wherein the thermal storage tip comprises stainless steel, and the insert comprises polypropylene.
5. The dispenser of claim 1 , wherein the thermal storage tip comprises a generally convex disk-shaped body, a generally curvilinear shape, a generally cylindrical shape, or a generally planar shape.
6. The dispenser of claim 1 , wherein the thermal storage tip has a volume of at least about 450 millimeters 3 and at most about 550 millimeters 3 .
7. The dispenser of claim 1 , further comprising a product delivery mechanism to dispense product from the dispenser, the product delivery mechanism comprising:
a reverse click motion delivery mechanism;
a click motion delivery mechanism;
a squeeze tube delivery mechanism;
an airless pump delivery mechanism; or
an aerosol delivery mechanism.
8. A dispenser comprising:
a housing having a reservoir for containing a product; and
a thermal storage tip coupled to the housing, the thermal storage tip having an application face for applying the product to a surface and a product delivery passageway extending through the thermal storage tip and terminating in an aperture in the application face, the thermal storage tip comprising a metal or a ceramic and having a volume of at least about 300 millimeters 3 and at most about 700 millimeters 3 .
9. The dispenser of claim 8 , wherein the surface finish of the application face is at least about 30 micro-inches.
10. The dispenser of claim 8 , wherein the thermal storage tip comprises stainless steel.
11. The dispenser of claim 8 , wherein the thermal storage tip is fixed to the housing against movement relative to the housing.
12. The dispenser of claim 8 , wherein the thermal storage tip comprises a generally convex disk-shaped body, a generally curvilinear shape, a generally cylindrical shape, or a generally planar shape.
13. The dispenser of claim 8 , wherein the thermal storage tip has a volume of at least about 450 millimeters 3 and at most about 550 millimeters 3 .
14. A dispenser comprising:
a housing having a reservoir for containing a product; and
a thermal storage tip coupled to the housing, the thermal storage tip including:
a body constituting a majority of the thermal storage tip, the body substantially defining a shape of an applicator; and
a shell sized and shaped to fit over the body and coupled to the body, the shell comprising a metal or ceramic and defining a face of the applicator of the dispenser, the shell being substantially the same shape as an exterior of the body.
15. The dispenser of claim 14 , the shell of the thermal storage tip having a mass of at least about 0.3 grams and at most about 0.6 grams.
16. The dispenser of claim 14 , the thermal storage tip having a volume of at least about 300 millimeters 3 and at most about 700 millimeters 3 .
17. The dispenser of claim 14 , the shell being coupled to the body by adhesive, press fit, snap fit, and/or one or more ribs or barbs.
18. The dispenser of claim 14 , the body of the thermal storage tip comprising a thermoplastic polymer, and the shell of the thermal storage tip comprising stainless steel.
