Abstract
The document concerns inflatable mattresses, in particular non-durable, inflatable mattresses. The inflatable mattress can be simply constructed from flexible sheet materials internally joined to form inflatable chambers.
Claims15
An inflatable mattress comprising:
- a flexible sheet of material encompassing an inflatable interior volume, the flexible sheet having an upper external surface, an upper internal surface, a lower internal surface and a lower external surface;
- wherein
- the upper internal surface is joined to the lower internal surface in a pattern of join lines forming a plurality of inflatable chambers, each chamber having an inflation port, wherein said inflation ports are arranged to be permanently sealed once inflated.
The inflatable mattress of any preceding claim, wherein said inflatable chambers are adjoined by intermediate flexible portions, preferably wherein the flexible portion is non-inflated.
The inflatable mattress of any preceding claim wherein the plurality of inflatable chambers are a series of at least ten adjacent inflatable chambers, each of said chambers extending across a width of the inflatable mattress, each chamber having an inflation port, and wherein the inflation ports are aligned along a long edge of the inflatable mattress.
The inflatable mattress of any preceding claim wherein said pattern provides a longitudinal manifold on a long side of the inflatable mattress, said manifold fluidly joining the inflation ports of the inflatable chambers.
The inflatable mattress of any preceding claim comprising polyethylene, polypropylene, polyethylene terephthalate, polyethylene furanoate, polyester, nylon, or polyvinyl chloride, preferably polyethylene, most preferably low density polyethylene (LDPE).
The inflatable mattress of any preceding claim comprising at least 60 wt %, based on the total weight of the mattress components, of thermoplastic polymer, more preferably at least 70 wt %, still more preferably at least 85 wt %, still more preferably at least 95 wt %, and most preferably at least 98 wt %.
The inflatable mattress of any preceding claim, wherein the inflatable mattress is non-durable, preferably temporarily reusable, disposable, or single-use.
The inflatable mattress of any preceding claim, further comprising a sleeve of flexible material dimensioned to retain a head end of the inflated mattress in a pillow format.
