  • the purpose of this invention is to solve the previously described disadvantages.
  • it proposes a cap comprising an interior wall and a bottom forming a reservoir.
  • the interior wall is cylindrical.
  • the reservoir is sealed off from the outside environment by an inner seal. It may therefore contain an active agent.
  • the interior wall and the bottom have thicknesses defined so as to prevent the treating agent from migrating towards the exterior of the reservoir.
  • This invention also proposes an air treatment device using a volatile treating agent contained inside of a permeable container that is closed by a cap having one of the characteristics specified above.
  • an embodiment such as this makes it possible to control the treatment process triggering phase simply and quickly, since it occurs after insertion of the cap into the permeable container.

  • FIG. 1 shows a device for treating air with a treating agent.
  • the device according to this invention is designed for treating air with a volatile treating agent contained inside of a permeable container 1 .
  • the treating agent is preferentially kept in the liquid state, or similarly, in a state in which it is capable of being absorbed by a spongy mass.
  • the treating agent is packaged by absorption into a spongy body 2 serving as a support for the treating agent housed inside the permeable container 1 .
  • the body 2 has the characteristic of being spongy while having the property of being able to easily soak up the treating agent.
  • the body 2 is, in particular, formed from a porous mass arranged like a plug, the volume of which occupies at least partially, e.g., almost all, of the volume of a chamber 6 formed by an internal hollowed-out portion of the permeable container 1 .
  • the body 2 is dry and is introduced into the receiving chamber 6 that the permeable container 1 comprises. It is subsequently soaked with a treating agent in the liquid state, in particular allyl isothiocyanate.
  • the shape of the body 2 is substantially complimentary to that of the chamber 6 , in order to optimise the occupation of the useful volume of the permeable container 1 , with the exception of a thin layer of air arranged between the body 2 and the wall of the permeable container 1 .
  • centring ribs 20 are arranged on the interior wall of the permeable container 1 .
  • the ribs 20 are positioned over a small angular portion.
  • this arrangement makes it possible to reduce the overall exterior dimensions of the permeable container 1 . Owing to these arrangements, and to the rigid nature of the permeable container 1 , its installation is facilitated.
  • the body 2 is shaped like a cylindrical plug. For example, it may be formed from a textile felt.
  • the volume of the chamber 6 is substantially equivalent to the volume of the body 2 .
  • a residual space between the body 2 and the lateral wall of the permeable container 1 is created by the ribs 20 , in order to have thin layer of air available for the diffusion process.
  • the treating agent After having soaked the body 2 in liquid form, the treating agent changes into a gas in the residual space between the body 2 and the lateral wall of the permeable container 1 .
  • the diffusion process enables gas migration of the treating agent through the lateral wall of the permeable container 1 so that it is released into the outside environment.
  • the permeable container 1 ensures gradual diffusion of the treating agent over a specific period of time.
  • the thickness and the surface of the lateral wall of the permeable container 1 are defined so as to ensure optimal diffusion of the treating agent via migration through the lateral wall.
  • a wall thickness ranging between 0.5 mm and 2 mm offers an acceptable compromise for ensuring optimal diffusion. More particularly, for an annual diffusion of 45 mg/day of treating agent, in particular allyl isothiocyanate, at a constant temperature on the order of 40° C., it is preferable to have a permeable container 1 thickness of the order of 0.9 mm, plus or minus 20%, for an overall surface area of 4200 mm 2 , plus or minus 10%.
  • these dimensions are dependant on the surrounding outside environment; more particularly, they are based on the temperature, and the required intensity of the diffusion process.
  • the permeable container 1 is equipped with a cap 4 for plugging the chamber 6 .
  • the cap 4 comprises a reservoir 12 containing the treating agent.
  • the treating agent is stored in the cap 4 and is separated from the body 2 .
  • the permeable container 1 As concerns the permeable container 1 , it is rigid and is formed from a permeable plastic material, e.g., 20% talc-filled polypropylene.
  • the permeable container 1 comprises a protuberance 8 that makes it possible to fasten the air treatment device onto the filtering medium or peripheral edge by means of a suitable clamp or clip. It is also possible to fasten the permeable container 1 onto the heating, ventilation and/or air-conditioning apparatus.
  • FIG. 2 shows a first embodiment according to this invention.
  • the cap 4 comprises a reservoir 12 containing the treating agent.
  • the reservoir 12 contains a sufficient amount of treating agent to impregnate the body 2 for optimal functioning of the air treatment device.
  • This reservoir 12 is made by the interior wall 14 and the bottom 16 of the cap 4 . It thus defines a volume ranging between 2 and 10 millilitres. Preferentially, it has a volume of 4.4 millilitres. However, these volumes are capable of being varied in order to correspond to the airflow treatment needs, in particular the desired service life of the treatment device and the climate surrounding the permeable container 1 .
  • the interior wall 14 is cylindrical. However, it is possible to consider providing a reservoir having a different internal geometry.
  • the cap 4 is made of plastic, in particular polypropylene. However, the thicknesses of the walls 14 and 16 are defined so that the cap 4 does not allow the treating agent to migrate towards the exterior of the cap 4 .
  • the reservoir 12 is sealed off from the outside environment by an inner seal 18 .
  • the inner seal 18 provides a perfect seal between the interior of the reservoir 12 and the outside environment. In this way, it is ensured that the treating agent is not able to migrate towards the exterior of the cap 4 .
  • the cap 4 contains a specific amount of treating agent that is insulated in a perfectly leak-proof manner from the outside environment. It is therefore possible to store these caps 4 for a long period of time without any reduction in the amount of treating agent due to uncontrolled migration through the walls 14 and 16 or the inner seal 18 .
  • the inner seal 18 is a sheet of aluminium that is firmly fastened onto the interior wall 14 of the cap 4 , by gluing or welding, for example.
  • the inner seal 18 may be made of a multilayer aluminium film.
  • FIG. 2 the device is described in a first position.
  • the cap 4 is inserted into the permeable container 1 in the high position.
  • the permeable container 1 comprises a lateral wall 22 .
  • the wall 22 is cylindrical.
  • the inside diameter of the wall 22 is identical to the outside diameter of the cap 4 .
  • An assembly such as this ensures a perfect fit between the cap 4 and the permeable container 1 . In this way, a perfect seal is made between the cap 4 and the permeable container 1 .
  • the wall 22 On its interior face, the wall 22 comprises indexing grooves 24 and 26 .
  • Groove 26 is arranged above groove 24 . The distance separating the grooves 24 and 26 determines the placement of the cap 4 in the high position and low position respectively.
  • the indexing grooves 24 and 26 cooperate with a boss 28 arranged on the exterior wall 17 of the cap 4 . In high position, the boss 28 cooperates with the indexing groove 26 . In low position, the boss cooperates with the indexing groove 24 .
  • the boss 28 serves as an index that is inserted into the indexing grooves 24 and 26 .
  • the embodiment described comprises two indexing grooves 24 and 26 . As needed, particularly in order to provide several intermediate positions between the high position and the low position, it is possible to have a larger number of indexing grooves.
  • Ribs 20 are also arranged on the internal face of the permeable container 1 . They are distributed evenly around the periphery and, ideally, over small angular portions.
  • the ribs 20 ensure centring of the body 2 , so that the latter is perfectly centred inside the permeable container 1 . Furthermore, by distributing the ribs 20 around the periphery, over small angular portions, this arrangement aims to facilitate the insertion of the body 2 into the chamber 6 while providing a space between the body 2 and the permeable container 1 . A layer of air occupies this space and promotes the release of the treating agent by allowing diffusion of the treating agent.
  • these ribs 20 are arranged over a portion of the height of the permeable container 1 , and preferentially at the upper portion of the permeable container 1 , so as to ensure centring of the body 2 in relation to the cap 4 and the reservoir 12 .
  • the body 2 is a dry stabilising material placed inside the chamber 6 of the permeable container 1 .
  • the stabilising material is a spongy body, e.g., made of felt.

  • the role of the body 2 is to prohibit direct contact between the treating agent, in liquid form, and the lateral wall 22 of the permeable container 1 .
  • contact between the treating agent and the lateral wall 22 would have effects on the migration path of the treating agent through the wall 22 , and would therefore alter the diffusion rate of the treating agent.
  • the body 2 comprises a perforator 30 .
  • the perforator 30 is made directly from a stabilising material. Ideally, it assumes a cone shape.
  • the role of the perforator 30 is to ensure the opening of the reservoir 12 and to release the treating agent when the cap 4 is in the low position, by piercing the inner seal 18 .
  • the cap 4 is placed on the permeable container 2 in a high position. It corresponds, in particular, to a storage position of the air treatment device prior to its final installation in an air treatment apparatus, such as a heating, ventilation and/or air-conditioning system.
