Abstract

A disposable unit dose package for frozen cosmetic or personal care products that can provide a chilling effect during application. The main components of the package are a reservoir and an applicator. The reservoir may be interiorly divided to hold more than one product. The applicator comprises a handle and one or more applicator heads depending from the handle. In use, a product in the reservoir is frozen, which causes the product to bond to the applicator head. The handle is used to lift the frozen product out of the reservoir, and draw the frozen product over the skin. As it melts from the heat of the skin, the product can be spread on the skin.

First claim

What is claimed is:

1. A unit dose package for a personal care product wherein the package is designed to house and apply a single dose of frozen product that can provide a significant chilling effect during application, the package comprising:
a reservoir ( 1 ) that comprises:
a wall ( 1 d ) that comprises an interior surface that has indentations, polygonal facets or a combination thereof, and that defines an interior space ( 1 c ) that has a volume;
a perimeter ( 1 a ) that defines an opening in the wall;
a flange ( 1 b ) that extends outwardly from the perimeter of the opening;

from 1 mL to 20 mL of a personal care product (P) disposed in the interior space ( 1 c ) of the reservoir ( 1 ), wherein the product is a liquid or semi-liquid at standard atmospheric pressure and temperature, and freezes at no lower than −20° C.; and
an applicator ( 2 ) that comprises:
a handle ( 3 );
an applicator head ( 4 ) that depends from the handle and that is disposed in the personal care product (P) located in the reservoir ( 1 ), and that has an outer surface ( 4 a ) with textural features ( 4 b ); and
a sealing disk ( 2 a ) that is sandwiched between the handle ( 3 ) and the applicator head ( 4 ), and that fits snugly against the perimeter ( 1 a ) of the reservoir ( 1 ) to seal the product (P) in the interior space ( 1 c ) of the reservoir;

wherein, when the product (P) is frozen, a user is able to grasp the handle ( 3 ) and lift the product out of the reservoir.

2. The unit dose package of claim 1 wherein:
the reservoir ( 1 ) is interiorly divided into two or more interior spaces ( 1 c , 1 c ′, 1 c ″);
a different personal care product is disposed in each interior space; and
the applicator head ( 4 ) is divided into as many sections ( 4 c , 4 c ′, 4 c ″) as there are interior spaces ( 1 c , 1 c ′, 1 c ″)of the reservoir, so that each interior space of the reservoir houses a section of the applicator head.

3. The unit dose package of claim 1 wherein the flange ( 1 b ) has at least one straight edge ( 1 h ).

4. A set of unit dose packages, the set comprising two or more unit dose packages according to claim 3 that are joined together along the at least one straight edge ( 1 h ) of the flange ( 1 b ).

5. The set of unit dose packages according to claim 4 wherein the unit dose packages are joined with a breakaway feature ( 1 i ) that allows individual reservoirs to be separated from the set.

6. A set of disconnected unit dose packages, the set comprising two or more unit dose packages according to claim 1 and a tray ( 6 ) that houses the disconnected unit dose packages.

7. The unit dose package of claim 1 wherein the outer surface ( 4 a ) of the applicator head ( 4 ) comprises grooves, indentations, raised dimples or combinations thereof.

8. The unit dose package of claim 1 wherein the handle ( 3 ) is attached to the sealing disk ( 2 a ) by hinge mechanism that enables the handle to lie flat against the sealing disk or be rotated 90° .

9. The unit dose package of claim 1 further comprising a barrier substrate ( 8 ) applied to the flange ( 1 b ) of the reservoir ( 1 ).

10. The unit dose package of claim 1 wherein the applicator head ( 4 ) comprises one or more sponges.

11. A method of applying a frozen personal care product comprising the steps of:
providing a unit dose package as claimed in claim 9 , wherein the product (P) is in a liquid or semi-liquid state;
storing the unit dose package in a freezer for a time sufficient to freeze the product (P) in the reservoir ( 1 );
peeling the barrier seal ( 8 ) off of the reservoir ( 1 );
grasping the applicator handle ( 3 ) and lifting the frozen product (P) out of the reservoir ( 1 );
spreading product (P) on the skin of a user by drawing the frozen product across the skin, such that the surface of the product melts from the heat of the skin;
continuing the step of spreading until the product has been depleted from the applicator head so that bare spots of the applicator head are able to contact the skin of a user; and
using the bare applicator head ( 4 ) to dress up the product (P).
