Spreading implement
DC CAFCFirst Claim
1. An implement for applying a volume of liquid to a treatment surface comprising:
- a support; and
a receptacle mounted on the support and defining a reservoir space with an open top and being configured to receive the volume of liquid in the reservoir space through the open top,wherein the receptacle includes a flexible membrane integrally forming a base and a wall, the wall being substantially transverse to the base and having a working surface configured to spread the liquid over the treatment surface, wherein the base has a continuous surface such that liquid cannot pass through the base,wherein the wall includes an inner portion which extends from the base to an upper end and an outer skirt portion, wherein the inner portion and skirt portion form a double-wall structure, andwherein at least the wall is resiliently deformable so in use the working surface maintains contact with the treatment surface when spreading the liquid.

Abstract
An implement 1 for applying a volume of liquid to a treatment surface. The implement includes a support 3 onto which is mounted a receptacle 2, the receptacle defining a reservoir space 4 which receives the liquid. The receptacle includes a wall 6 having a working surface that is used to spread the liquid over the treatment surface. The wall 6 is resiliently deformable so in use the working surface maintains contact with the treatment surface when spreading the liquid. The implement has a specific application in applying a transdermal lotion to the axilla area of the user. A system for transdermal administration of a physiological active agent from a liquid composition and a method of conducting the transdermal administration.

24. A system for transdermal administration of a physiologically active agent from a liquid composition, the system comprising:
-
a container configured to contain the liquid composition including the physiologically active agent, a dispensing device configured to deliver liquid from the container; and an applicator configured to apply the liquid to an area of skin for transdermal administration, said applicator including a receptacle defining a reservoir space which receives a volume of the liquid composition from the container, the receptacle having a base that is resiliently deformable and a resiliently deformable wall that is formed integrally with the base from a flexible membrane, the wall being substantially transverse to the base and having a working surface that is used to spread the liquid composition over the area of the skin, wherein the base has a continuous surface such that liquid cannot pass through the base. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
