Abstract: The present invention relates to containers and methods suitable for uses such as liquid hot-fill processes. More specifically the invention relates a containers having gas permeable vents with an integral sealing means that is externally activatable by non-mechanical means to effect hermetic sealing of the containers after filling.

Abstract: Methods of addressing a biomolecule to a selectively addressable electrode are described. A permeation layer overlying a plurality of selectively addressable electrodes is provided. The permeation layer includes a reactive group that is adapted to bond to a biomolecule and that requires activation through a chemical transformation before bonding to the biomolecule. At least one selectively addressable electrode is biased such that a pH change occurs in an overlying solution of the at least one selectively addressable electrode. The reactive group in a portion of the permeation layer above the at least one selectively addressable electrode is then chemically transformed to an activated reactive group as a result of the pH change. A biomolecule is then bound to the permeation layer overlying the at least one selectively addressable electrode through the activated reactive group.

Abstract: The present invention generally encompasses methods of coating which control of the release rate of agents from a polymeric matrix. This control over the release rate of agents provides for control over, inter alia, the therapeutic, prophylactic, diagnostic, and ameliorative effects that are realized by a patient in need of such treatment. In addition, the control of the release rate of agents also has an effect upon the mechanical integrity of the polymeric matrix, as well as a relationship to a subject's absorption rate of the absorbable polymers.

Abstract: Disclosed are cooling tubes or straws for beverages and other liquids. The tubes or straws comprise a porous matrix to effect the cooling a liquid contained within by pervaporation.

Abstract: Disclosed are cooling jackets for containers for beverages and other liquids. Such a jacket comprises a porous matrix as an element of the jacket body to effect the cooling of the jacket by pervaporation of a liquid contained within the jacket body. The jacket therefore cools a liquid within a container maintained in direct contact with the jacket.

Abstract: Disclosed are self-cooling containers for beverages and other liquids. Such containers comprise porous matrices as elements of the container bodies to effect the cooling of contained liquids by pervaporation. The liquid vapor can pass through the porous matrix directly to the environment or to a collector or trap comprising an absorbent material in contact with the container. Also disclosed are self-cooling containers incorporating insulative sleeves that reduce radiative warming of container surfaces yet permit sufficient pervaporative flux to cool containers residing within such sleeves.

Abstract: Disclosed are beverage containers and closures for beverage containers that are vented for the purpose of reducing negative pressure or vacuum that builds up inside the container when a beverage is being consumed therefrom. Also disclosed are closures which provide for chemical treatment of a liquid by a porous treatment matrix when the liquid is dispensed through the closure.

Abstract: Disclosed are beverage and liquid containers that use pervaporation to cool a liquid or material residing in the container. The pervaporative cooling is preferably achieved by use of porous matrices which allow for the passage through the matrix of small quantities of volatile components from a liquid or beverage, such as water or alcohol, the evaporation of which cools the container by virtue of the latent heat of evaporation of the liquid. Alternatively, a pervaporative sleeve may be used to cool a container residing within or in contact with the sleeve.
