TECHNICAL FIELD

The present invention relates to a pillow.

BACKGROUND ART

In the field of pillows there is a constant need to have a wide range of products which meet the varied demands/needs of users in terms of color, stiffness/softness, breathability and comfort .

To date pillows are made differently from each other in terms of materials and/or structural characteristics. Each pillow is obtained by using practically appropriate equipment that, in some cases, may be converted or adapted to produce pillows different from those originally intended. This adjustment requires, however, long and sometimes complex procedures of machinery cleaning with unavoidable waste of material, in itself being relatively expensive, and consequent costs not always justified by the production volumes requested.

DISCLOSURE OF INVENTION

The purpose of the present invention is to provide a pillow, which allows to solve in a simple and economic way the above problem and will appear, at the same time, easy and inexpensive to manufacture.

According to the present invention a pillow is provided comprising a first body of foamed elastic or viscoelastic material, and at least a second body of foamed elastic or viscoelastic material, distinct from one another; the foamed material of said second body further comprising, at least one additional component selectable among a fragrant substance, an antimicrobial or anti-mite substance, an extract or juice of a substance of vegetable origin and a substance of at least partial change of the thermal inertia of relative said foamed material. Preferably, in the pillow defined above, the foamed material of said second body comprises a fragrant substance in a variable percentage between 0.01 and 2, and/or an antimicrobial or anti-mite substance in a variable percentage between 0.1 and 7, and/or a substance of at least partial change of the thermal inertia of the antimicrobial or anti- mite substance in a variable percentage between 0.1 and 50.

Preferably, moreover, in the pillow defined above the foamed material of said second body comprises an extract or juice of a substance of vegetable origin in a variable percentage between 0.1 and 30. Conveniently, moreover, said first and second body are independent from one another and are glued or chemically connected together so as to produce a pillow formed in one piece.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will now be described with reference to the accompanying drawings, which illustrate an example of a non- limiting embodiment, wherein:

Figure 1 is a perspective view of a preferred embodiment of a pillow according to the dictates of the present invention;

Figure 2 is a section along line II-II of Figure 1.

BEST MODE FOR CARRYING OUT THE INVENTION

In figure 1, with 1 is indicated 1, as a whole, a pillow comprising a support shaped body 2 and an intermediate body 3, distinct from the body 2 and, conveniently, housed in a recess 4 of the body 2 itself.

The bodies 2 and 3 are delimited by respective resting surfaces 2a and 3a connected to one another to define respective parts of a resting surface 6 of the pillow 1. In the particular example described, the bodies 2 and 3 are crossed by a plurality of passages 5 extending from one side of the bodies 2 and 3 themselves and through their respective surfaces 2a and 3a so as to make the pillow 1 breathable. One or, conveniently, both bodies 2 and 3 are made of foamed elastic material, for example polyester or polyether. Alternatively, one or, conveniently, both bodies 2 and 3 are made of viscoelastic foam material, i.e. of a material having the peculiarity of not reacting to the compression with values proportional to crushing and having a preset hysteresis area.

Conveniently, the bodies 2 or 3 have a hardness ranging between 0.8 and 20 Kpa, a damping percentage variable between 10 and 80 and a density ranging between 20 and 120 g/dm ³ .

The intermediate body 3 characterizes the type of pillow and differs from the body 2 for the fact that are mixed to the elastic or viscoelastic material components characterizing the pillow 1 and, in particular, dyes, in a variable percentage between 0.1 and 10 and selectable between pigments, pigment dispersions in plasticizers or mixtures of polymeric dyes.

Alternatively or in combination with the dyes, to the elastic or viscoelastic material are added fragrant substances in a variable percentage between 0.01 and 2% and, for example, extracts of natural origin, such as lavender, or synthetic molecules . Alternatively or in combination with the dyes and the fragrant substances, to the elastic or viscoelastic materials are added antimicrobial/anti-mite substances of natural origin in a variable percentage between 0.1 and 7%, for example Neem juice or silver particles, or of synthetic nature, for example, organic salts of ammonium, N-butyl-1,2- benzodiisotiazolin-3-one.

Alternatively or in combination with dyes, with the fragrant substances and with the antimicrobial/anti-mite materials to the elastic or viscoelastic material are added substances of vegetable origin, in a variable percentage between 0.1 and 30% in form of extracts, such as Arnica, or juice, for example Aloe or castor oil, or also modifiers to the thermal inertia of the elastic or viscoelastic material in a variable percentage between 0.1 and 50% and commonly known as a P. CM. material such as for example coated polymer paraffins, having the function of absorbing at least in part the heat generated by the body.

The pillow 1 is produced by forming the bodies 2 and 3 separately from one another within respective molds or cutting in shape the bodies 2 and 3 themselves from blocks of material previously formed. Once the bodies 2 and 3 are obtained they are coupled together and stably connected to one another in a stable manner, for example by gluing, heat sealing or other equivalent connection methods.

Alternatively, according to a different embodiment method, the pillow 1 is manufactured by forming one of the bodies 2,3, introducing said body in a forming mold (not shown) and on the same body is poured an expanding liquid which, at expansion completed, defines the other body. During the expansion, the expanding liquid comprises a portion of the body originally formed by generating an intermediate junction layer of the two bodies 2 and 3, which thus constitute part of a single body made in one piece.

Alternatively, according to a different embodiment method, the intermediate body 3 is coupled to the support body 2 by means of releasable connecting devices designed to allow interchangeability of the body 3 while maintaining unchanged the body 2.

From the foregoing it is evident that the pillow 1 described, for the fact of being made in whole or in part of elastic or viscoelastic material presents, in itself, high comfort characteristics for the user. Moreover, since the body 3 is independently formable from the body 2 it is possible to arbitrarily change the characteristics of the body 3, and thus customize the pillow 1 depending on the requests of the individual user, but maintaining particularly low the costs deriving from said customization. In fact, to a base material of the body 3, during the preparation step of the related compound, can be conveniently added components or substances which, accordingly may be chosen among different components or substances different from each other, modifying, depending on the percentage and their nature, not only the appearance but also the fragrance, the hygienic-sanitary conditions and the attractiveness of using the body itself.

In this way, it is possible to form a breathable "extended family of pillows" all characterized by one or at most two basic materials, only one of which, in the example specifically defining the body 3, is, however, modified prior to the completion of the respective body to endow the corresponding pillow with singularity of one or more distinctive features with respect to the other pillows of the same family. Finally, the fact of coupling the body 3 to the body 2 in a releasable way, allows the individual user, to vary in an almost arbitrary way the characteristics of its own pillow according to his/her needs. From the foregoing it is evident, that to the pillow 1 described modifications and variations can be provided without thereby departing from the protective scope defined by the independent claim. In particular, the pillow 1 can have a different shape from that indicated by way of example, as well as geometrically and dimensionally different from those indicated may be the bodies 2 and 3 and the corresponding surfaces 2a and 3a.

Finally, the pillow 1 could comprise further personalized bodies 3 not necessarily equal to each other and the same bodies 3 may be arranged in different positions from that indicated and not necessarily housed in the body 2 but simply superimposed upon the body 2 itself.
