Definitions

  • Shoe insole and system consisting of a left and a right
  • the present invention relates to a shoe insert and a system consisting of a left and right shoe insert and a fragrance container.
  • foot odor One of the most common causes of foot odor is the secretion of sweat around the feet.
  • the foot odor does not come directly from the secreted sweat, but rather arises when bacteria decompose the sweat and produce butyric acid in the process.
  • the prior art there are insoles for use in shoes, fragrances being introduced into the materials of the insole once during the manufacturing process.
  • the products available so far have the disadvantage that the fragrances used have a very artificial effect and / or have a very short fragrance duration, such that after a short time the effect of the scented shoe insole wears off and the product is designed as a disposable product.
  • the object of the present invention is to reduce the unpleasant foot odor and odor inside shoes and to improve the climate of the shoes in the long term.
  • a shoe insert comprising a cover layer, a damping layer and an absorbent core for absorbing a liquid fragrance, the damping layer having a depression on its upper side for receiving the absorbent core, the cover layer being arranged over the damping layer and the absorbent core and covers the latter, the layers being connected to one another, and a perforated recess being formed in the cover layer in the region of the absorbent core for charging the absorbent core with liquid fragrances.
  • the embodiment according to the invention has the advantage that the absorbent core for absorbing the liquid fragrances can be refilled again and again via the perforated recess when the effect of the fragrance applied has subsided. Furthermore, the proposed configuration enables the user of the previously described shoe insert to be able to perfume the shoe insert according to his own wishes by introducing the preferred liquid perfume. In particular, the user can use his preferred brand of perfume or deodorant to scent his shoe insole himself.
  • the liquid fragrances are preferably fragrance oils, which have the advantage that they have a longer duration of action, in the sense that the fragrances evaporate more slowly. Furthermore, the fragrance oils have a higher viscosity than usual liquid fragrances, such that the fragrance oils have the additional advantage that they emerge more slowly from the absorbent core and are more securely enclosed there.
  • the absorbent core can be drizzled or charged with a liquid fragrance through the hole-shaped recess in the cover layer, the fragrance being able to penetrate into the absorbent core or the fabric and in particular the textile fabric of the absorbent core and be safely stored or stored there for several days or weeks. is included.
  • the scent can be released into the surrounding shoe space as a gaseous phase and ensures a pleasant freshness in the shoe space and can mask unpleasant smells.
  • a direct escape of the liquid fragrance is prevented by the intended arrangement of the overlap of the absorbent core with the cover layer, so that the liquid fragrance, for example, cannot be absorbed directly through the sock of the shoe wearer.
  • the cover layer can completely cover the underlying damping layer and the absorbent core excepted therein and only in the area below the cover layer arranged suction core have a hole-shaped recess. In an alternative form, however, it can also be provided that the cover layer only covers a partial area of the upper surface of the damping layer, but at least covers the surface of the absorbent core.
  • connection of the individual layers of the shoe insert in particular the aforementioned cover layer and damping layer, can in particular be implemented by gluing the individual layers to one another in such a way that a permanent mechanical connection or adhesion of the layers to one another is ensured.
  • the absorbent core is glued into the depression of the damping layer.
  • connection of the individual layers and optionally the absorbent core can, however, also be implemented using alternative methods, for example by joining the starting material of the damping layer in a mold while still in the liquid state during an injection molding process with the absorbent core and / or the other layers of the shoe sole and subsequently the material of the damping layer is cured, as a result of which a mechanical connection of the damping layer to the other layers and optionally the absorbent core is established.
  • the absorbent core can be formed as a fragrance reservoir from a textile fabric.
  • the absorbent core which is formed from the textile fabric, has the advantage that it can store the fragrance, for example the fragrance oil, for a specified period of time.
  • the suction core thus forms a kind of reservoir or memory for the liquid fragrance. Due to the design of the absorbent core as a textile fabric, the fragrance oil is evenly absorbed and distributed throughout the absorbent core in such a way that the fragrance is released slowly and continuously. Furthermore, the liquid fragrance is not permanently bound in the absorbent core, such that it can be removed from the absorbent core again by means of a washing process.
  • the absorbent core can have at least two layers of an upper layer made of a Tex-'til fabric and a viscose layer arranged below.
  • the liquid fragrance in the constricting including Ne viscous layer in which the fragrance is stored.
  • the shoe insert comprises a fabric cover, the fabric cover being arranged as an additional layer below the cushioning layer and optionally completely covering its underside. It can also be provided that the aforementioned fabric cover is inseparably connected, for example glued, to the damping layer.
  • the fabric cover has the advantage that the insertion of the shoe insert into the shoe is simplified and the layers of the shoe insert arranged above the fabric cover are supported by the fabric cover during use, so that the service life of the shoe insert according to the invention can be increased.
  • the fabric cover can form the underside of the shoe insert according to the invention.
  • the cover layer can be formed from a liquid-impermeable and at the same time gas-permeable membrane.
  • the membrane designed in this way prevents liquid fragrance from escaping from the absorbent core into the environment, but allows the gaseous fragrance to pass through, whereby the interior of the shoe can be scented.
  • the hole-shaped recess is designed as a valve device.
  • the valve device can be designed in such a way that a supply of liquid fragrance from the surroundings of the shoe insert into the absorbent core is made possible, but an escape of liquid fragrance from the absorbent core is prevented.
  • the cover layer of the shoe insert is formed from a microfiber cover.
  • the microfiber cover can absorb the moisture, in particular the sweat secreted by the foot. Furthermore, the microfiber cover can be provided with antibacterial properties, whereby the development of the odor in the shoe can be prevented or reduced. In addition, the microfiber cover has heat-regulating properties, which means that the shoe climate is further improved by the microfiber cover.
  • the depression of the damping layer is formed by a circular punched out on its upper side.
  • the circular punching can for example have a diameter in the range of 1-2 cm, preferably about 1.3 cm.
  • the damping layer is made essentially from ethylene vinyl acetate (EVA).
  • EVA ethylene vinyl acetate
  • the use of ethylene vinyl acetate as the base material for the production of the cushioning layer has the advantage that the EVA material provides the shoe insert with a cushioning and at the same time restoring effect.
  • the EVA damping layer can have a layer thickness in the range from 1 mm to 5 mm, particularly preferably the layer thickness is around 2 mm in the middle area of the shoe insert and runs out thinner all around in the edge area of the shoe sole.
  • the layers of the shoe insert are connected by means of a neoprene adhesive or, alternatively, by means of a solvent-free spray adhesive system.

  • convex or concave surface courses can be provided to adapt the shape of the shoe sole to an existing shoe bed.
  • the layers, the absorbent pads and the gluing of the shoe insert according to the invention can be configured in such a way that they are machine washable, in particular machine washable at 30 ° C.
  • the configuration as a machine-washable shoe insert has the advantage that different fragrances of the liquid fragrances can be used consecutively with one and the same shoe insert and thus the shoe insert according to the invention is designed as a product that can be used repeatedly.
  • the fragrance introduced into the absorbent core can be completely neutralized or washed out in the washing machine so that the shoe insert can be used again.
  • the aforementioned embodiment also has the advantage that the shoe insert can also be disinfected and thoroughly cleaned during the washing process by adding suitable washing additives.
  • the dimensions of the suction core essentially correspond to the dimensions of the depression in the damping layer and the absorption core is embedded in the depression.
