摘要:
Disclosed is a method for making an appliance adapted to transfer to, or associate with, the skin or tissue of a user, a composition, e.g., a moisturizing formulation. Because of possible interactions between the formulation and/or formulation ingredients and elastic polymers that may be employed to help give the appliance elastic qualities, the method comprises steps for providing an elastic layer or member and a shielding layer or member, with the shielding member interposed between the composition/formulation and the elastic member. The shielding layer and elastic layer may be integrally connected to one another, as in a film comprising two layers. Typically the shielding layer will be impermeable to the composition/formulation (e.g., by employing polymers, such as polypropylene comprising crystalline portions, such that the mass transport of the formulation through the shielding member is stopped or substantially impeded).

This invention provides a guard rail post for use on scaffolding of the type used in the construction of buildings. The guard rail post comprises an elongated member having securing means for securing the guard rail post to a vertical support member of the scaffold, positioning means for mounting the guard rail post in fixed relationship to a scaffold work platform and means for connecting guard rails to the post at a fixed distance above the work platform.

Disclosed is an appliance adapted to transfer to, or associate with, the skin or tissue of a user, a composition, e.g., a moisturizing formulation. Because of possible interactions between the formulation and/or formulation ingredients and elastomeric polymers that may be employed to help give the appliance elastomeric qualities, the appliance comprises an elastic layer or member and a shielding layer or member, with the shielding member interposed between the composition/formulation and the elastic member. Typically the shielding member will be impermeable to the composition/formulation (e.g., by employing polymers, such as polypropylene comprising crystalline portions, such that the mass transport of the formulation through the shielding member is stopped or substantially impeded).
