Definitions

  • the present invention relates to a device for releasing a volatile substance, in particular a fragrance or an insecticidal active ingredient, into the ambient air with a housing made from a first material which has a vegetable fibrous material, in particular paper, cardboard or cardboard.
  • Such devices are known, for example, from US Pat. Nos. 4,258,874 A, US 4,166,565 A and US 4,279,373 A and have a housing which is formed, for example, from paper or cardboard.
  • Dispensing means are typically located within the housing and deliver a volatile material, e.g. B. a fragrance can deliver.
  • a volatile material e.g. B. a fragrance can deliver.
  • the volatile substance can diffuse through the paper or cardboard housing even before the device is actually used. As a result, only a reduced quantity of the volatile substance is then available during the period of use of the device.
  • Another disadvantage is that residues that are not biodegradable typically remain in the housing after use of the device. This makes the disposal or recycling of such devices more difficult.
  • Another device for dispensing a fragrance is known from US Pat. No. 4,712,737.
  • This device comprises a housing made of coated cardboard and a dispensing device which is arranged inside the housing and which can be formed, for example, from a gel system, a woven fabric or a fleece. Even with this device, non-biodegradable residues can remain in the housing after use.
  • the object of the present invention is to facilitate the disposal or recycling of a device for dispensing a volatile substance into the ambient air.
  • a device for releasing a volatile substance, in particular a fragrance or an insecticidal active substance, into the ambient air is proposed, with a housing made of a first material which is a vegetable fibrous material, in particular paper, cardboard or cardboard, and has a barrier layer with a barrier function against the permeation of the volatile substance and with an insert made of a second material arranged within the housing, the second material being provided with the volatile substance, in particular impregnated, with the second material being one of the following materials or one or more of the following materials:
  • Such devices can also be referred to as room air fresheners or insect killers or insect repellents.
  • the device according to the invention comprises a housing made of a first material.
  • This first material has a vegetable fibrous material, for example paper, cardboard or cardboard, and can therefore be disposed of or recycled without great effort after use.
  • Another component of the device is an insert made of a second material, which differs from the first material.
  • the first and second material can be selected specifically for the respective function. This is because while the first material of the housing has to form a barrier function for the volatile substance before the device is used, the second material should have the best possible properties relevant to the release of the volatile substance.
  • the second material is a vegetable fiber or sucrose or starch or a mineral material.
  • the second material is provided with the volatile substance, in particular impregnated, so that it can be released from the housing to the ambient air.
  • the insert of the device can also be disposed of or recycled without great effort after use. It is possible to dispose of the housing and the insert together, i.e. without having to separate them, e.g. in the paper waste or packaging waste ("yello
  • the first material has a barrier layer with a barrier function against the permeation of the volatile substance.
  • a barrier layer is understood to mean a layer which has a low permeability for the volatile substance.
  • the barrier layer can prevent the volatile substance can escape from the housing prior to activation of the device. Due to the barrier layer, such a high partial pressure of the volatile substance can be maintained in the interior of the housing that further out-diffusion of the volatile substance from the insert is avoided.
  • the barrier layer preferably consists of polyamide, polyester, aluminum, ethylene-vinyl alcohol copolymer, silicon dioxide or polyvinyl alcohol. These materials have good barrier properties, in particular low permeability to volatile substances, in particular fragrances or insecticidal active ingredients.
  • a configuration with polyvinyl alcohol offers the advantage that the barrier layer is water-soluble and can therefore be disposed of in a simplified manner. Overall, simplified recycling of the device is made possible.
  • the first material may have multiple barrier layers.
  • the barrier layers have different permeabilities for different volatile substances.
  • a housing can be obtained which has a barrier function for a number of volatile substances, for example for a number of substances in a mixture of substances, e.g.
  • the barrier layer is arranged in contact with a layer made of the vegetable fibrous material.
  • a further layer for example a protective layer or a sealing layer, can be arranged between the barrier layer and the layer made of the vegetable fiber material.
  • the barrier layer is preferably arranged between two layers of vegetable fiber. Such a configuration offers the advantage that both the inside and the outside have the visual appearance of the vegetable fiber material. Furthermore, the barrier layer can be protected from environmental influences by the two layers of vegetable fiber. If a barrier layer made of polyvinyl alcohol is used, it can be protected by the two layers, for example, from the effects of water and thus undesired damage to the barrier layer can be prevented. Optionally, a further layer can be arranged between the barrier layer and the layers of vegetable fiber, for example a protective layer or a sealing layer.
  • the barrier layer is designed as a coating of a layer made of the vegetable fiber, in particular as a coating on an inside of the housing. It is particularly preferred if the first material has precisely one layer of the vegetable fiber material, which is coated on the inside with the barrier layer.
  • the housing has a base on which the housing can stand on a substrate, the base being designed to be water-repellent.
  • the housing can have a water-repellent coating in the area of the standing surface.
  • the coating may include a nanomaterial.
  • the vegetable fibrous material is paper or cardboard or cardboard, for example groundwood cardboard or cellulose cardboard.
  • the vegetable fibrous material is wood pulp, in particular groundwood, or cellulose or cotton fibers or grass fibers.
  • An advantageous embodiment of the invention provides that the mineral material is ground stone or bentonite or silica gel.
  • an advantageous embodiment of the invention provides that the insert has several layers of the second material connected to one another, in particular by means of an adhesive, in particular several layers of groundwood cardboard.
  • the fact that the insert is made up of several layers of vegetable fiber means that the weight of the insert and thus also the weight of the entire device can be adjusted. It has been found that users perceive such devices as having a higher value if the devices are of a certain weight - ie not too light.
  • a predetermined weight of the device can therefore be set by selecting the number of layers, for example four or five or six or seven or eight.
  • the increased weight of the insert results in the advantage that the volatile substance, in particular the fragrance or the insecticidal active substance, is distributed over a larger mass of the insert.
  • the layers may be bonded by one or more nails, staples, eyelets, bolts or strips, for example a strip of metal, wood, a polymer, glass or stone.
  • the insert has several layers of groundwood, it is advantageous if the groundwood includes a layer of groundwood that is arranged between two cover layers.
  • the cover layers preferably each comprise pulp or paper, particularly preferably pulp and paper.
  • the wood pulp board preferably has a thickness in the range from 0.5 mm to 2.5 mm, for example 0.8 mm, 0.9 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0mm or 2.4mm.
  • the layers each have a basis weight in the range from 350 g/m 2 to 950 g/m 2 , preferably from 450 g/m 2 to 600 g/m 2 or from 600 g/m 2 up to 800 g/m 2 .
  • basis weight plies have been found to be particularly good at adjusting the weight of the pad.
  • the layers each have a thickness in the range from 0.2 mm to 2.5 mm and a weight per unit area in the range from 350 g/m 2 to 950 g/m 2 , preferably a thickness in the range from 0 8 mm to 1.0 mm and a basis weight in the range from 350 g/m 2 to 400 g/m 2 or a thickness in the range from 1.1 mm to 1.3 mm and a basis weight in the range from 450 g/m 2 to 550 g/m 2 or a thickness in the range from 1.3 mm to 1.5 mm and a basis weight in the range from 490 g/m 2 to 570 g/m 2 or a thickness in the range from 1.5 mm to 1 .7 mm and a basis weight in the range from 580 g/m 2 to 660 g/m 2 or a thickness in the range from 1.7 mm to 1.9 mm and a basis weight in the range from 630 g/m 2 to 750 , a thickness in the range
  • the adhesive is biodegradable.
  • a biodegradable adhesive By using a biodegradable adhesive, an insert can be provided that can be disposed of even more easily, in particular recycled or industrially composted.
  • the adhesive particularly preferably corresponds to European standard EN 13432 and is in their sense “completely biodegradable”. Alternatively, an adhesive that is not biodegradable can be used.
  • the insert has at least one first layer, which is in particular designed over the entire surface, and has at least one second layer, which has at least one recess, in particular a punched-out area.
  • the punch-out may form a receptacle for the fugitive material.
  • the volatile material for example in liquid form, to be placed in the receptacle formed by the recess.
  • the volatile material can move into the insert from the recess.

  • the time-temperature indicator includes heat and UV light sensitive pigments. These pigments can be activated by a manufacturer of the device at the end of the manufacturing process by irradiation with UV light, with the UV dose used depending on the shelf life.
  • the heat-sensitive and UV-light-sensitive pigments are particularly preferably covered by a UV-light-impermeable film, so that subsequent manipulation by UV light is not possible.
  • the housing has a first housing part and a second housing part, the first housing part and/or the second housing part comprising a receptacle for the insert, the first housing part having one or more openings, in particular through-openings , through which the volatile substance can be released into the ambient air, and the second housing- part from a closed position, in which it covers the openings, in particular through-openings, of the first housing part, into an open position, in which the openings, in particular through-openings, of the first housing part are released for dispensing the volatile substance.
  • the release of the volatile substance can be activated by sliding the two housing parts relative to one another.
  • the second, in particular outer, housing part covers the passage openings in the first, in particular inner, housing part. Because the first material of the inner and outer housing members limit, specifically prevent, escape of the volatile material, the partial pressure of the volatile material within the housing remains constant at a level that prevents escape of the volatile material from the liner.
