  • Polypropylene is characterized by high hardness, resilience, stiffness and heat resistance. Short-term heating of polypropylene articles is even possible up to 140 ° C. At temperatures below 0 ° C., some embrittlement of the polypropylenes occurs, which, however, can be shifted to much lower temperature ranges by copolymerization of the propylene with ethylene (EPM, EPDM). In general, the impact resistance of polypropylene can be improved by modification with elastomers. The chemical resistance is good as with all polyolefins. An improvement in the mechanical properties of the polypropylene is achieved by reinforcement with talc, chalk, wood flour or glass fibers. Polypropylenes are even more sensitive to oxidation and light than PE, which is why the addition of stabilizers (antioxidants, light stabilizers, UV absorbers) is required.

  • the silicone valve 6 remains only in its open position, as long as the pressure within the fragrance dispensing device 1 is large enough and an air flow through the opened silicone valve 6 is passed. If the internal pressure of the fragrance dispensing device 1 falls below a predefined value, the silicone valve 6 closes and prevents further release of perfume.
  • FIG. 1a-b odor dispenser Another embodiment of the known from Fig. 1a-b odor dispenser is shown in Fig. 1 c-d.
  • the carrier material 4 is a liquid which is received in a container closed with a permeable membrane.
  • the membrane is designed such that fragrance or other active substances pass through the membrane, but not the carrier material.
  • the container may be fixed to one of the walls 2 or 3. As already described at the outset, a squeezing of the container walls 2, 3 generates a pressure and an air flow through which fragrance-laden air is released from the fragrance dispensing device into the environment.
  • the container opening 5 can be closed by a removable closure cap 7. This is shown in Fig. 2a-c.
  • the closure cap 7 can - as shown in FIGS. 2a-b - be completely detachable from the perfume dispensing device 1 or, as can be seen from FIG. 2c, be integrally formed on the perfume dispensing device 1 via a hinge.

  • the fragrance dispensing device 1 is connected to the cardboard 10 via the fastening means 8.
  • the carton 10 is for example freely movable or fixedly placed on a shelf 9.
  • the fragrance dispensing device 1, the fastening means 8 and the carton 10 as a presentation element together form a fragrance presentation system, wherein the fragrance delivery device is associated with a product and the fragrance released by the fragrance delivery device 1 substantially corresponds to the fragrance releasable by the product.
  • fragrance presentation systems 1, 8, 10 in a rack 9 next to one another, which is shown by way of example in FIG. 4.
  • the carton 8 may have graphic or textual information elements 11.

  • a fragrance-laden flow is generated, which forms a flow cone at the outlet from the container opening 5, which is indicated in Fig. 5 by the dashed line.
  • the flow cone is directed to the nose of the user, so that the fragrances can be specifically absorbed.
  • the conical flow ensures that the fragrances are released as locally and spatially as possible.
  • the flow cone 12 preferably has an opening angle ⁇ between 0 ° and 10 °. 5, the opening angle ⁇ of the flow cone 12 is formed between the axis 14 perpendicular to the opening plane of the container and a leg of the flow cone 12th

  • the valve lip 16 is formed in such a way that the valve disk 17 can move up and down in the valve cylinder 15, which is indicated by the arrows in FIG.
  • valve plate 17 initially rises from its rest position (partial image (A)) into the end position (partial image (B)).
  • the silicone valve 6 is thus arranged so resiliently in or on the container opening that it moves until reaching a defined internal pressure in the container X from a first rest position to a second end position.
  • the silicone valve 6 opens by the triangular segments of the slit 14 of the silicone valve 6 being folded outwards and air laden with volatile substance being released to the environment. (Partial illustration (C))

Abstract

L'invention concerne un dispositif de distribution (1) comprenant un récipient (X) indéformable, possédant des parois (2, 3) flexibles, les parois (2, 3) étant configurées de manière à pouvoir être écrasées par la main d'un utilisateur, une ouverture de récipient (5), l'ouverture de récipient (5) étant couverte d'une vanne en silicone (6). L'intérieur du récipient (X) est au moins partiellement rempli d'au moins un matériau support (4) pour au moins une substance volatile. Le récipient (X) et la vanne en silicone (6) sont configurés afin qu'un écrasement du récipient (X) par un utilisateur provoque une augmentation de la pression à l'intérieur du récipient (X), ce qui ouvre la vanne en silicone (6) et envoie dans l'environnement, par la vanne en silicone (6), de l'air chargé de la substance volatile.
