A seating device has a seating platform and at least one leg supporting it in its elevated position.

Isocyanate-free foam using carbon Michael addition chemistry

A method of making a foam comprising the following steps. A mixture is created comprising (i) a first reactant comprising triglyceride having acrylate functionality, (ii) a second reactant comprising diacrylate, and (iii) a blowing agent. The mixture is expanded to create a froth. The first and second reactants of the froth are reacted to create the foam.

Method of making a foam

A method of making a foam from a polymerizable resin includes the following steps. A thermally-activated initiator having a temperature below the initiation temperature is combined with an elevated-temperature solution having the polymerizable resin and carbon dioxide at a temperature above a promoted temperature to create a resulting mixture having a temperature above the promoted temperature. The resulting mixture is expanded by decreasing the pressure of the mixture to create a froth having a plurality of cells formed by carbon dioxide that expanded out of solution. The polymerizable resin within the froth is cured to create a foam.

Method of making foam

The presently disclosed subject matter relates generally to method of producing thermoplastic foam from a blend of polyolefin and acrylated epoxidized fatty acid using a phsyical blowing agent. Specifically, the presently disclosed subject matter includes embodiments wherein the acrylated epoxidized fatty acid is added to the polyolefin resin in an amount of from about 0.1% to about 10%, based on the total weight of the resin. The presently disclosed subject matter also includes the foam produced by the disclosed method.

Method of foaming polyolefin using acrylated epoxidized fatty acid and foam produced therefrom

One aspect of the invention pertains to a device for mixing and dispensing fluids, which generally includes a housing; a mixing chamber having a first inlet for introducing a first fluid into the mixing chamber, a second inlet for introducing a second fluid into the mixing chamber, and an outlet through which fluid may exit the mixing chamber; and a valving rod received within the mixing chamber and movable between an open position, in which the first and second inlets are in fluid communication with the mixing chamber, a cleaning position, in which the valving rod substantially seals closed the first inlet but does not seal closed the second inlet, and a closed position, in which the valving rod substantially seals closed the first and second inlets.

Device for mixing and dispensing fluids

The invention is a thermoplastic film having a heat resistant coating. The film is particularly useful in the preparation of bags and associated packaging systems that are used for protecting and packaging articles. Typically, the heat resistant coating has a melting range that is greater than the melting temperature of the thermoplastic film and exceeds the temperature of the heat generated during foam formation. As such, packaging films and bags that are prepared in accordance with the invention help prevent foam-in-bag cushions from fusing together. Particularly useful heat resistant coatings include ink varnishes and resins that are solvent-based, water-based, or energy cured.

Heat resistant foam-in-bag packaging

A packaging system for producing a foam-in-bag cushion upon demand includes a bag of flexible plastic film and defining therein an enclosed space which is vented to the outside of the bag, a foam precursor packet positioned at a predetermined location within the enclosed space in the bag and being formed of a barrier material. The packet includes first and second compartments with a first frangible seal separating the first and second compartments which when ruptured will permit the contents of the compartments to be mixed to form a foam cushion and a second frangible seal between one of the compartments and the enclosed space in the bag. A first foam precursor component is contained in the first compartment of the packet and a second foam precursor component is contained in the second compartment of the packet. The frangible seals have a peel strength of at least about one pound per inch and less than about twelve pounds per inch and more particularly a peel strength of about one pound per inch to about seven pounds per inch. The frangible seals are formed by providing bands of printed area on the facing surfaces of the material forming the packet which is arranged in a matrix of printed and unprinted areas. The printed areas prevent the surfaces from being joined by heat sealing and the matrix is such that a frangible seal of the desired peel strength is formed.

Foam in bag packaging system and method for producing the same

A polyol blend is disclosed for making polyurethane foams. The blend includes a first polyol having a functionality of about 2, a hydroxyl number ranging from about 20 to about 90, and an equivalent weight ranging from about 600 to about 2800; a second polyol having a functionality ranging from about 4 to about 8, a hydroxyl number ranging from about 200 to about 600, and an equivalent weight ranging from about 90 to about 280; and a third polyol having a functionality ranging from about 2.5 to about 4, a hydroxyl number ranging from about 15 to about 500, and an equivalent weight ranging from about 180 to about 4000. The polyol blend is capable of reacting with an isocyanate compound in the presence of water to produce a foam having a density ranging from about 0.5 to about 5 pounds/ft.sup.3, a compressive strength ranging from about 3 to about 20 psi, and an airflow ranging from about 10 to about 1000 cc/minute.

Polyol blend, multi-component system for producing polyurethane foam,

A foam-in-bag packaging system and method of forming the same is provided in which a bag of flexible plastic film material includes superposed panels joined around their peripheral edges to define an enclosed space which is vented to the outside of the bag by venting perforations in the panels, a packet or pouch of barrier material capable of maintaining foam precursor components in a stable, unreacted state for an extended time period is positioned in the enclosed space in the bag adjacent one end thereof and secured from movement therefrom, the packet has first and second compartments therein separated by a first frangible seal extending across the packet and first and second foam precursor components contained respectively in the first and second compartments, the packet has a second frangible seal between one of the compartments and the enclosed space in the bag, the bag being folded along spaced transverse fold lines into a relatively compact form and being folded along a fold line coincident with the first frangible seal to form a mechanical barrier between the first and second compartments of the packet, and a detachable label holding the bag in its folded, compact form.
