Definitions

  • the present invention relates to a pillow. More specifically, the present invention relates to a pillow that can be used in hospital applications or in other sectors such as the civil, naval, automotive, aeronautical or railway ones.
  • a pillow just like a mattress, plays a fundamental role in the sleep quality of a person.
  • his/her head and neck shall be aligned with the rest of the body. Therefore, the function of a pillow is to allow the body to remain in a correct position during the sleep stage, while also facilitating breathing.
  • Specific pillows are known for some time which are used, in particular, by persons who shall stay in bed for extended periods of time, typically during a hospitalization, or by immobilized persons who live at home. These pillows feature orthopaedic characteristics that can be classified into two categories: biomechanical characteristics and microclimatic characteristics.
  • the biomechanical characteristics concern pillow elasticity, tensile strength, and compression strength.
  • the microclimatic characteristics typically concern humidity resistance and thermal capacity, which concur to develop a given contact temperature and humidity between the pillow and the person laid thereon.
  • sanitary pillows shall also be fireproof, hypoallergenic, anti-decubitus (i.e. they shall prevent and heal skin injuries caused by decubitus) and strongly breathable, in particular in the zone that is in contact with the user or patient.
  • sanitary pillows which adopt different technical solutions.
  • One of the most known solutions is a so-called "memory foam” pillow, i.e. a pillow made from a viscoelastic polyurethane foam which deforms under the human body's weight and heat. These pillows memorize the shape of the user's head and deform correspondingly. Once the head's weight is removed, the pillow quickly recovers its initial shape.
  • An alternative to the "memory foam” pillow consists of a latex pillow, which is made from a natural latex processed in such a way as to generate a foamy material which strength and elasticity is imparted to via a vulcanization process.
  • Other types of pillows also exist, such as, for instance the WaterlilyTM pillow (also called water foamed pillow, obtained through a polyurethane foam processing process), a goose feather pillow, a three-dimensional polymer, or 3D polymer, pillow, usually made from a polyester polymer, or a water pillow.
  • a drawback of the prior art pillows consists in that each of them features a number of advantages concerning some of the above-mentioned characteristics, but also a number of disadvantages concerning other characteristics.
  • a "memory foam" pillow features optimum ergonomic and orthopaedic properties, but is little breathable.
  • a latex pillow is ergonomic and easy to wash, but it is not orthopaedic nor breathable nor anti-decubitus.
  • Another problem of the prior art pillows also relates to a poor durability of their correct shape.
  • document CA 2897584 A1 illustrates a multilayer pillow provided with a plurality of layers made from different materials, superimposed to each other. At least one of these layers consists of a bag containing water.
  • An object of the present invention is therefore to provide a pillow that is capable of solving the above-mentioned drawbacks of the prior art in an extremely simple, cost-effective, and particularly functional manner.
  • an object of the present invention is to provide a pillow that combines all advantages of the prior art pillows together, so as to be, in particular, fireproof, comfortable, ergonomic, orthopaedic, antiallergic, breathable, anti-decubitus, handy, durable, and antibacterial.
  • Another object of the present invention is to provide a pillow that retains its correct shape for a long time.
  • a pillow according to the present invention can comprise:
  • the pillow 10 comprises an external envelope, or surface layer, 12, made from a three-dimensional breathable, fireproof, and antibacterial fabric.
  • the external envelope 12 is made from a preferably non-quilted fabric.
  • the external envelope 12 encloses at least one inner breathable layer 14 made from a fireproof three-dimensional polymeric material.
  • the external envelope 12 completely envelopes the inner breathable layer 14 made from a fireproof three-dimensional polymeric material, so that the inner surface of such external envelope 12 completely covers the outer surface of such inner breathable layer 14.
  • the external envelope 12 and the inner breathable layer 14 made from a fireproof three-dimensional polymeric material are removably reciprocally coupled together.
  • the external envelope 12 is thus provided with opening means 18 configured for making it possible to extract the inner breathable layer 14 made from a fireproof three-dimensional polymeric material from such external envelope 12.
  • At least one intermediate ergonomic layer 16 made from a foamy and fireproof material, externally coupled with the envelope 12 in a removable manner and configured for at least partially enclosing the inner breathable layer 14.
  • the intermediate ergonomic layer 16 is also irremovably coupled with the inner breathable layer 14 in correspondence with their respective contact surfaces.
  • the foamy material used for the intermediate ergonomic layer 16 is of the shape memory type.
  • This material is possibly formed of a shape memory polyurethane foam, also briefly referred to as "memory foam". Such material is possibly provided with one or more through holes in order to achieve appropriate breathability characteristics.
  • the three-dimensional polymeric material that the inner breathable layer 14 is made from consists of a polymer of the class of polyesters. More specifically, the inner breathable layer 14 consists of a plurality of elastic components (springs) made from a three-dimensional polymeric material, preferably a polymer of the class of polyesters.
  • the intermediate ergonomic layer 16 made from a foam material with the inner breathable layer 14 made from a three-dimensional polymeric material results in a synergic technical effect that goes beyond a simple summation of the advantages achievable by such layers if taken individually.
  • the foamy material that the intermediate ergonomic layer 16 is made from receives the body's weight and fits its pressure, thus leaving the three-dimensional polymeric material of the inner breathable layer 14 sufficiently little compressed as to retain its own breathability.
  • the shape memory foamy material that the intermediate ergonomic layer 16 is made from has a density ranging from 40 kg/m 3 to 60 kg/m 3 . Even more preferably this density substantially equals 50 kg/m 3 .
  • the three-dimensional polymeric material that the inner breathable layer 14 is made from has a density ranging from 20 kg/m 3 to 40 kg/m 3 . Even more preferably this density substantially equals 30 kg/m 3 . It is obviously possible to select other density values both for the shape memory foamy material and for the three-dimensional polymeric material.
  • Each of the inner breathable layer 14 and the intermediate ergonomic layer 16 is obtained starting from a respective slab of material.
  • the external envelope 12 is obtained from a three-dimensional fabric in order to achieve the highest breathability characteristics.
  • the pillow 10 as a whole can be manufactured in the standard dimensions for a pillow, such as, for instance, 43 x 72 x 13.5 cm.
  • the overall thickness of the pillow 10, including its respective inner layers, can range from about 13 cm to about 18 cm.
  • the procedure to obtain the pillow 10 is the following:
  • the pillow of the thus conceived present invention is, in any case, susceptible of numerous modifications and variants, all falling into the same inventive concept; moreover, all details are replaceable with technically equivalent elements.
  • the material used, as well as shapes and dimensions, can be whatsoever depending on the technical requirements.
