Definitions

  • the invention relates to an insole, particularly to a pre-shaped insole, to be placed in a shoe.
  • the invention furthermore relates to a container for insoles, and to an assembly of such a container and at least one insole.
  • Insoles have been known for quite some time now in many varieties and variations. Such insoles are often sold packaged in pairs, and are used for offering comfort to the foot. Their principal functions are offering support to the foot in the shoe and offering shock absorption, their secondary function may be the reduction of adverse effects of enclosing the foot in a shoe for a shorter or longer period of time, such as the discomfort of foot odour.
  • insoles are meant to be used for a longer period of time.
  • the insoles loose their secondary functions after some time as the effect of active substances providing said secondary functions usually is temporary.
  • the insoles may after some time loose their shape as a result of which the walking comfort is reduced.
  • a further drawback of such pre-shaped insoles is that they are rather thick which reduces the fit of the footwear of the user.
  • a separate insole that shoe manufacturers place in their footwear moreover usually has to be removed for getting the right fit.
  • thin insoles are known that are meant for single use or for use during a shorter period of time.
  • a drawback of these thin insoles is that they are limp and as a result usually difficult to place in the shoe.
  • the active substances, that may be incorporated in such a thin insole usually are in direct contact with the ambient as a result the effect of the active substances decreases very rapidly or is totally undone prior to the actual use.
  • a further object of the invention is to package the insoles in new, at least alternative way.
  • the invention provides an insole to be placed in a shoe, wherein the insole comprises two or more layers and wherein at least one of the two or more layers comprises active substances and particularly is impregnated therewith.
  • the two or more layers are connected to each other by arranging one or more polymers in between them from a group comprising: ethylene vinyl acetate, polyurethane, polyvinyl acetate, polycaprolactone, polyethylene and copolyamide.
  • one or more polymers offer an important contribution to the firmness of the laminate.
  • the one or more polymers may be added in several forms.
  • thermoforming an at room temperature solid polymer to beyond its melting point after which it is arranged as a viscous liquid on the substrate to be glued (so-called "hot melt technique"), after which the second substrate is arranged and pressed and finally the laminate is cooled in air.
  • a third possibility is arranging the polymer on the substrate in the form of a waterborne dispersion by means of rollers, after which the second substrate is arranged and pressed and subsequently the laminate is dried in an oven.
  • the polymer is arranged in a quantity of 30 to 70 g/m 2 , so that there is sufficient adhesion, yet it does not form a blocking layer, so that water vapour and air are still able to pass through.
  • ethylene vinyl acetate, poly vinyl acetate or polycaprolatone are used. Active substances such as for instance moisture and/or odour absorbing substances may be added to these polymers.
  • liquid active substances such as perfumes, preferably as micro capsules or as inclusions mixed with the polymer are incorporated in the glue layer.
  • Starch, cyclodextrin, polysaccharides and gelatin may be used for the walls of the micro capsules.
  • Said materials have the advantage of being fully or partially soluble in moisture, as a result of which the micro capsules under the influence of moisture action and friction will not release their contents until desirable to the user.
  • the active substances - in liquid or solid form - will have to have the property of being soluble or emulsifiable therein. If such is not the case then these active substances will have to be arranged on the substrate in a separate action, for instance by spraying. This is also the case when the polymer is arranged as a warm molten liquid.
  • the insole is made so thin as to obtain a proper fit and walking comfort without having to remove the insoles that may be present in the shoe supplied by the manufacturer.
  • the thin insoles according to the invention offer a more acceptable fit.
  • the breathing capacity may be better because air has to travel a shorter distance through the thin insole.
  • thin insoles according to the invention have the advantage that thin insoles take up less volume, which is advantageous in the processing, the transport and storage, and that a relatively large number of such thin insoles may be packaged in a convenient consumer packaging.
  • the two or more layers each have their own functionality.
  • the insole comprises a moisture permeable layer.
  • said moisture permeable layer is provided with openings for transport of moisture to an underlying layer of the insole.
  • the moisture permeable layer is entirely or partially made of one or more materials selected from a group comprising: polyester, polypropylene, polyacrylate and viscose.
  • Particularly suitable materials for this upper layer are polypropylene and/or polyester, optionally treated with surfactants that ensure accelerated moisture transport.
  • the moisture permeable layer comprises a knitting, fabric or non-woven.
  • the moisture permeable layer is provided with one or more active substances selected from a group comprising: surfactants, perspiration inhibitors, antibacterials, microorganism growth inhibitors, fatty matters, perfumes, odour absorbing substances and odour inhibitors.
  • active substances selected from a group comprising: surfactants, perspiration inhibitors, antibacterials, microorganism growth inhibitors, fatty matters, perfumes, odour absorbing substances and odour inhibitors.
  • the perspiration inhibitors comprise one or more selected from a group comprising: aluminium compounds, zinc compounds, tea tree oil and salvia oil.
  • the moisture permeable layer forms an outermost layer of the insole for placing at a side of the insole facing away from the sole of the shoe.
  • the thickness of the moisture permeable layer is smaller than or equal to 0.6 mm, and preferably is larger than or equal to 0.3 mm.
  • the insole comprises a shock absorbing layer.
  • said shock absorbing layer is entirely or partially made of an elastomer, such as a rubber, foamed material and/or a non-woven.
  • the shock absorbing layer is entirely or partially made of one or more materials selected from a group comprising: latex foam, polyurethane foam, ethylene vinyl acetate, thermoplastic rubber and polyvinyl acetate.
  • the shock absorbing layer is entirely or partially made of non-woven, and wherein the non-woven comprises one or more materials selected from a group comprising: polyester, viscose, blends of polyester and viscose, and cellulose wood pulp.
  • the shock absorbing layer or an additional layer comprises a polyester non-woven material, preferably provided or impregnated with a very high dose of active carbon for effective control of undesirable foot odours.
  • the shock absorbing layer is provided with one or more active substances selected from a group comprising: moisture absorbing substances, odour absorbing substances, cooling substances, perfumes, anti-perspirants, antibacterials, cooling substances and active carbon.
  • the moisture absorbing substances comprise cellulose derivatives, preferably carboxymethyl cellulose, hydroxyethyl cellulose, starch, xanthan gum, sodium polyacrylate, viscose and/or wood pulp.
  • the active substances may be incorporated in the shock absorbing layer in the form of micro capsules and/or in the form of inclusions.
  • micro capsules and/or inclusions preferably comprise an outer wall that is soluble in moisture.
  • the thickness of the shock absorbing layer is smaller than or equal to 3.0 mm, and preferably is larger than or equal to 0.3 mm.
  • the insole comprises a supporting layer.
  • said supporting layer comprises a foam material.
  • the foam material comprises ethylene vinyl acetate foam and/or polyethylene foam.
  • the supporting layer is perforated.
  • the supporting layer comprises recesses in which a resilient material has been placed.
  • the resilient material comprises an elastomer, preferably a thermoplastic elastomer.
  • the recesses are at least arranged in a part of the insole for supporting a heel of the user and/or in a part of the insole for supporting the ball of the foot of the user.
  • the resilient materials comprise visco-elastic materials, such as for instance a thermoplastic elastomer. This particularly occurs in recesses at positions where the ball of the foot and the heel of the foot rest, because during the walking motion the most pressure is exerted at those places.
  • a thermoplastic elastomer such as for instance a thermoplastic elastomer.
  • said supporting layer forms an outermost layer of the insole for placing at a side of the insole facing the sole of the shoe.
  • the thickness of the supporting layer is smaller than or equal to 6 mm.
  • the insole comprises at least three layers, wherein the at least three layers comprise a moisture permeable layer, a shock absorbing layer and a supporting layer.
  • the shock absorbing layer preferably is placed in between the moisture permeable layer and the supporting layer.
  • Such an insole generally consists of at least three layers, comprising a moisture permeable upper layer of woven fabric, an intermediate layer having a large shock absorbing and water absorbing capacity, and a bottom layer offering support and able to provide the insole with an optimal fit.
  • the upper layer is characterised by its ability to transport the moisture secreted by the foot as fast as possible to the layer or layers of the insole that lie underneath it.
  • An important secondary property of the upper layer is the comfortable feel to the skin of the foot so that the insole can also be used bare-footed.
  • the upper layer further is wear-resistant and colourproof which gives the insole an acceptable durability.
  • the colour of the upper layer is selected such so as to be least striking in comparison with the colour of the inside of the majority of the commercially available shoes.
  • the material of the upper layer may furthermore be impregnated with substances that inhibit the growth of microorganisms, so as to reduce the development of undesirable foot odours.
  • the intermediate layer preferably is made of polyurethane foam having both a large shock absorbing and water absorbing capacity.
  • Polyurethane foam provides an advantageous shock absorption and has a more permanent elasticity and less permanent deformation as a result of discontinuous pressure load during the walking motion than for instance latex foam.
  • the polyurethane foam is for instance made by pressing together and simultaneous binding ground open-celled flexible polyurethane foam, which results in a relative high density of approximately 200 kg/m 3 .
  • Another advantage of this material is that it has a large water absorption capacity. Moreover said material is capable of absorbing water very quickly.
  • pigments, active carbon and antibacterials may very well be added to this material.
  • the intermediate layer or an additional layer comprises a polyester and/or viscose non-woven with sodium polyacrylate therein.
  • sodium polyacrylate is chemically bound, glued or imbibed in the non-woven.
  • Said sodium polyacrylate has a very high moisture absorbing capacity, due to which perspiration moisture of the foot is rapidly taken away.
  • the bottom layer or supporting layer preferably is provided with a foam material, for instance cross-linked ethylene vinyl acetate foam, offering support to the foot and the body.
  • Said ethylene vinyl acetate foam preferably has a density of 115 to 135 kg/m 3 , and a hardness of 35 to 40 Shore A.
  • the foam material has a low permanent deformability, namely a thickness reduction of 5% at the most after 10800 pressing motions (testing method Satra PM 159), and proper shock absorbing properties characterised by a reduction in the fall deceleration of DIN rubber of at least 25% (testing method Satra TM 142).
  • the third layer of the insole offers a certain degree of firmness, it usually turns out to be insufficient for obtaining the desired firmness.
  • gluing by means of one or more polymers, a good firmness can be obtained.
  • extra firmness is obtained by providing the insole with a slightly hollow shape. Said hollow shape may for instance be obtained by means of raised edges.
  • the insole may also be given a slight curvature which, after the insole has been placed in the shoe, is ended by the pressure of the foot.
  • the insole may in the longitudinal direction be provided with a line-shaped thinning, along which the insole may bend during insertion. Naturally several line-shaped weakenings may be arranged for this purpose.
  • the wanted firmness is obtained by using ethylene vinyl acetate foam having a density of 70 to 90 kg/m 3 , a hardness of 20 to 25 Shore A.
  • a bottom layer of ethylene vinyl acetate foam having a closed cell structure is perforated for making the transport of moisture possible.
  • the perforations have a round shape having a diameter larger than or equal to 1 mm, and preferably smaller than or equal to 5 mm.
  • the two or more layers are connected to each other by means of a glue connection, fusing together and/or ultrasonic welding.
  • a glue connection fusing together and/or ultrasonic welding.
  • the insole may be given an optimal fit.
  • active substances such as perfumes and antibacterials may be added to the glue.
  • the insole comprises indentations and/or continuous perforations extending through one or more layers.
  • the one or more layers are pressed together near the indentations and/or continuous perforations.
  • the indentations and/or continuous perforations are defined by hollow needles or little tubes.
  • the active substances show a phase transition in a temperature range of 20 to 36 degrees Celsius.
  • the insole compounds may be added that melt at approximately 32 degrees Celsius for extracting energy and heat from the foot, as a result the insole may offer a cooling effect to the feet.
  • the insole compounds may be added that solidify at approximately 30 degrees Celsius for releasing energy, as a result of which the insole may give a heating effect to the feet.
  • Such substances may also be combined, as a result of which at too high a temperature of the foot the substances extract heat and at too low a temperature of the foot release energy. As a result the foot temperature is constantly kept in a comfortable temperature zone.
  • the insole comprises heat-conducting elements.
  • the heat-conducting elements extend from a portion of the insole which when used is placed near the foot arch to a portion placed near the toes and/or a portion placed near the heel. Heat from the warmer foot arch may thus be transported to the colder projecting parts of the feet.
  • the active substances show a phase transition under the influence of a mechanic shock.
  • the active substances comprise an aqueous solution of sodium acetate.
  • the aqueous solution of sodium acetate is super cooled so that it crystallises when the solution is activated by the user by means of a motion of the toes. Due to the mechanic shock crystallisation heat is released as a result of which the insole warms the foot.
  • An advantage of this solution is that it can be reused by reactivating the sodium acetate by heating the sole and subsequently cooling it down.
  • the insole comprises heat reflecting ceramic fibres.
  • Such ceramic fibres transmit thermal energy as a result of the vibrations in far infrared.
  • the feet may be offered extra warmth by means of the insole in this way as well.

  • the active substances comprise one or more selected from a group comprising: ammonium chloride, potassium nitrate, ammonium nitrate and Glauber salt (Na 2 SO 4 * 10 H 2 O).
  • the active substances are enclosed in a semi-permeable matrix.
  • a semi-permeable matrix for instance allows perspiration moisture to pass through, yet stops transport of the compounds to the outside.
  • Using such a semi-permeable matrix is particularly advantageous in combination with the active substances incorporated herein, such as for instance the above-mentioned active substances that are soluble in moisture and during dissolving in moisture are subjected to an endothermal reaction.
  • the active substances comprise magnetic, antistatic and/or electrically conductive materials.
  • the insole is provided with magnetic means for discharging magnetic fields.
  • said insoles will stimulate the ganglions of the feet and thus improve the blood circulation and increase the oxygen discharge level.
  • the insole may provide the entire body of the user with extra energy.
  • the insole is provided with antistatic and/or electrically conductive materials.
  • Said antistatic and/or electrically conductive materials may stop the build-up of static electricity in the body and discharge it via the ground, as a result of which a safeguard against electric shocks can be obtained.
  • the insole has a thickness that decreases from the heel side towards the toe side, and it is preferably provided with upward oriented support portions at the positions where, when used, the foot arch and the heel rest.
  • the thickness of the insole, at least a portion of the insole for supporting a heel of a user is smaller than or equal to 6 mm, and preferably smaller than or equal to 4 mm.
  • the thickness of the insole decreases from a heel side of the insole towards a toe side of the insole.
  • the thickness of the toe side is smaller than or equal to 1 mm.
  • this embodiment with decreasing thickness relates to a pre-shaped insole to be placed in a shoe.
  • the shape of the insole is selected such so as to offer an optimal fit in the majority of commercially available shoes (of a certain size), and to distribute the pressure of the body exerted on the insole as much as possible over the surface of said insole.
  • This is characterised by accurately chosen lengths and breadths, by the thickness that decreases from the heel side to the toe side and by upward oriented supporting parts at positions where the foot arch and the heel rest.
  • the thickness course is chosen such that it is possible to insert the insole in the shoe without having to remove the inner sole that is already present in the shoe and without causing a squeezing effect.
  • the side edges of the insole comprise a raised edge.
  • the insole is able to better support the foot, particularly the heel of the user, and particularly sideward as well. Due to this raised edge the foot is also cooled off to a lesser degree at lower ambient temperatures.
  • the insole comprises an outermost layer which at a side oriented to an outer side of the insole is provided with size marks. The insole may thus be cut to size by the user.
  • the invention provides a method for manufacturing an insole as described above, wherein:
  • the die presses the laminate in the wanted profile shape.
