Abstract: A cell structure for a mattress or support where parallel cells are connected together substantially at their middle plane in series so that at least 5 tubes are sealed together in the series. In certain embodiments, feed cells are provided transverse the cell structure and the feed cells are sealed to the cell structure and include punches to allow fluid pressure form the feed cells to introduce into the cell structure. A rail cell is provide outwards of the feed cells and in certain aspects, the rail cell and alternating ones or groupings of the cells in the cell structure are provided with different pressure sources.

Abstract: An article of manufacture that has at least three layers of sealable material. There is at least one first seal between at least two of the layers in a first area having a first sealing affinity effected at a first sealing parameter. There is also at least one second seal between at least two more layers, where at least one of these two layers is distinct from the at least two layers joined by the first seal, in a second area having a second sealing affinity effected at a second sealing parameter, where the second sealing parameter is different than the first sealing parameter, thereby allowing for sealing of discrete areas of the article in discrete steps.

Abstract: An article of manufacture that has at least three layers of heat sealable material. There is at least one first heat seal between at least two of the layers in a first area effected at a first temperature. There is also at least one second heat seal between at least two more layers, where at least one of these two layers is distinct from the at least two layers joined by the first heat seal, in a second area effected at a second temperature, where the second temperature is different than the first temperature, thereby allowing for heat sealing of discrete areas of the article in discrete steps.

Abstract: Devices and methods for fusing materials using a heating element, where the overall mass to be sealed varies along the length of the seal. According to the invention, the heating element has a different profile in different areas. According to some aspects, the thickness and/or cross section of the heating element is different in different areas so that when a current is passed through the heating element, each area heats to a different degree. In some aspects, the heating element is shaped to conform to the shape of the parts to be fused together. The transition between areas of different thickness or cross-sectional area, or between areas of different shape may be sharply defined. This abrupt transition may be created by machining the heating element to a finished shape rather than bending flat stock to shape.

Abstract: A cell matrix expandable structure includes of a plurality of interconnected cells normally in flat form but readily expandable into the form of a container upon the introduction of fluid. The structures may be made out of recyclable films. Methods of manufacturing the cell matrix in a continuous manufacturing process are also disclosed.

Abstract: An expandable structure is manufactured using sheets of thermoplastic material sealed together. The expandable structure has a concertina pattern on its sides that allows the structure to expand and collapse like an accordion. The concertina pattern is cut into the sheets of material rather than being folded into the material to speed up the manufacturing process.

Abstract: A fluid dispensing device has a container made from a flexible material defining an interior fluid storage region and a flexible metering housing having a metering chamber in fluid communication with the fluid storage region, the flexible metering housing having a button heat sealed to a base plate. A unidirectional intake valve is disposed between the container and the flexible metering housing. A unidirectional output valve is in fluid communication with the flexible metering housing. The button has a stepped flange towards an outer edge of said circular shape and the base plate has a stepped flange corresponding to the stepped flange of the button.

Abstract: A hanging liquid dispenser is provided that includes a pump and valving for delivering the fluid material when the dispenser is operated by the user in a controlled fashion. The hanging dispenser includes a main body that serves as a fluid reservoir and has an eyelet which is suitable for use in hanging the dispenser from a suitable support. In addition to including the ability to hang, the dispenser preferably includes a pump for metered dosing of the fluid within the dispenser when operation of the pump delivers a controlled volume of the fluid as desired by the user.
