Definitions

  • the present invention relates to mattress covers, also known as mattress protectors or pads, and in particular to mattress covers that are impermeable to liquid such as water, sweat, urine etc.
  • Different types of protection are used to protect bed mattresses against e.g. urine. It is particularly relevant at hospitals and nursery homes, but it may also be desired at e.g. hotels or in private homes.
  • a simple solution is to place a plastic film under the sheet, but that is uncomfortable to lie on due to the accumulated heat, the noise, and the relatively low friction and thereby sliding of the sheet on the plastic film.
  • these products are often disposable or non-washable.
  • the mattress protection item is often desired to provide a certain comfort as well as protecting the mattress from liquids such as urine and sweat.
  • Mattress covers are known in the art, having a quilted padded bolster, and a liquid-impermeable layer fastened to the bolster along the edges thereof.
  • Such mattress covers are very difficult to handle in a washing and drying process and in the succeeding making of the beds. The reason is that the impermeable layer and the rest of the mattress cover are movable relative to each other and therefore easily form folds in the impermeable layer and/or causes seam slippage.
  • the impermeable backing layer of these known mattress covers are formed by a laminated liquid-impermeable membrane.
  • a further disadvantage of the known mattress cover is that the laminated impermeable layer makes a noise when the person lying in the bed moves around.
  • a liquid impermeable bed cover is described in US-A-5 249 320 .
  • the object of the invention may be obtained by a mattress cover according to claim 1.
  • the upper layer and the padding are joined by quilting.
  • the padding is made from polyester hollow fibres or other synthetic fibres.
  • the fabric of the liquid-impermeable layer is made from polyester, polyurethane or other synthetic composition.
  • the mattress cover In the choice of material for the mattress cover, it must be ensured that it can be completely disinfected from unwanted bacteria through an industrial washing process, and that the fibres maintain their other properties (e.g. liquid-impermeability, colour, softness, strength etc) when submitted to such washing processes.
  • the various parts of the mattress cover in synthetic fibres this can be obtained at lower washing temperatures than what is necessary for natural fibres such as cotton or other celluloid fibres.
  • the liquid-impermeable layer comprises a laminated fabric.
  • the liquid-impermeable layer of the mattress cover comprises a fabric having a liquid impermeable coating.
  • the coating of the liquid-impermeable layer may preferably be made from polyurethane, acrylic or the like.
  • the liquid-impermeable layer may be formed by a laminated fabric.
  • the mattress cover may further comprise a peripheral skirt, adjustable straps, anchor style elastic bands in combination or as individual methods for fixation of the mattress cover on a mattress.
  • the object of the invention may also be obtained by a method of manufacturing a mattress cover according to claim 10.
  • liquid impermeable layer is provided by coating a sheet of synthetic fibres.
  • the invention is particularly useful in hospitals, nursery homes and the like.
  • Fig. 1 shows, schematically, a prior art mattress cover 1 comprising a tick 2 formed by an upper layer 2a and a lower layer 2b, a padding 3, and a liquid-impermeable layer 4.
  • the liquid-impermeable layer 4 is only fastened to the tick 2 at the hem 5 thereof.
  • Figs. 2 and 4 show a mattress cover 1 according to two aspects of the invention.
  • the tick of the mattress cover 1 comprises an upper layer 2a and a lower layer 2b, a padding 3 there between and a liquid permeable layer 4, forming a backing of the mattress cover 1.
  • Fig. 3 shows schematically that the tick 2 and the padding 3 are joined e.g. by quilting before the liquid-impermeable layer 4 is fastened thereto.
  • the actual pattern of the quilting may differ from the one illustrated in Fig. 3 .
  • the liquid-impermeable layer 4 is fastened to the tick 2 at the hems 5 and a number of positions (10, see fig. 6 ) across the surface, where the fastening positions may follow the quilting pattern.
  • the fastening should be carried out by a method that does not destroy the liquid-impermeable coating such as inverted quilting/stitching which does not penetrate the liquid-impermeable layer 4.
  • the quilting/stitching must penetrate the padding 3 and the upper layer 2a for proper fixation of these layers, or it may only involve the liquid-impermeable layer 4 and the lower layer 2b adjacent thereto (if layer 2b is used).
  • the quilting/stitching may be made in any desired pattern.
  • An alternative method for fixation may be pin-sonic or other known heat setting processes.
  • the mattress cover 1 comprises an upper layer 2a, a padding provided under the upper layer 2a and a liquid permeable membrane or layer 4 forming a backing for the mattress cover and substituting the lower layer 2b in the first aspect of the invention.
  • the liquid-impermeable layer 4 comprises a fabric and a coating (not shown) or a laminated fabric.
  • a coating is used, the coating is preferably added to the fabric before the joining of the mattress cover 1 to ensure an even and liquid-impermeable surface.
  • the coating may typically be polyurethane, but other materials, such as PTFE, that ensure the liquid impermeability of the layer may also be used.
  • the properties of the materials must not be significantly influenced by a large number of washes at temperatures high enough to ensure the necessary cleaning of the actual material used for the mattress cover 1.
  • the mattress cover 1 may be made from polyester fabric for the tick 2 and hollow polyester fibres for the padding 3.
  • the fabric of the liquid-impermeable layer 4 may also be polyester which may have a looser texture than the tick 2.
  • the impermeability of the mattress cover 1 may be tested e.g. by simply pouring a glass of water on the upper fabric 2a of the mattress cover 1 and checking that is it does not penetrate the liquid-impermeable layer 4. Since the product is expected to have to be washed a large number of times, it must also be ensured that it is still liquid-impermeable after a significant number of washes at the necessary temperatures.
  • the impermeability of the mattress cover has been tested in accordance with DS/EN 20811:1993 by accredited laboratory. Furthermore the mattress cover has been tested in accordance with and complies with DS/EN 1276 and DS/EN 1040. These tests performed on mattress covers having tick made from synthetic fibres at both 60° and 95° wash.
  • Fig. 6 shows schematically a sectional view of a mattress cover 1 having a peripheral skirt 6 to cover, wholly or partly, the sides of a mattress (not shown) on which the mattress cover 1 is placed.
  • a purpose of such a skirt 6 is to keep the mattress cover 1 in place both when making the bed and when the bed is in use. Another purpose may be to protect the sides of the mattress, and still another purpose may be for aesthetic reason.
  • the skirt 6 may have an elastic band 7 at the hem 5 to ease the placing of the mattress cover 1. It may also comprise other means for placing and keeping the mattress cover in position, such as adjustable straps or anchor style elastic bands (not shown). Such straps or elastic bands may also be used for fastening a mattress cover not comprising skirts.
