Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] This invention relates to an air treatment device using a volatile treating agent housed inside of a permeable container, and more particularly the cap of such a device. [0002] Such devices are used to ensure the disinfection, sterilisation and/or deodorisation of air, particularly in heating, ventilation and/or air-conditioning systems, and more particularly the passenger compartment of a vehicle. Its object is a cap for a container containing a volatile air treatment agent, in particular for treating the air circulating though such a system. [0003] Devices are known for treating air by using a volatile treating agent placed inside a permeable container, in order to gradually diffuse the treating agent through the wall of the permeable container over a specific period of time. This treatment, for example, is a fungicidal, antimicrobial or odorising treatment. [0004] According to a first known solution, the treating agent is a liquid contained inside a gas-permeable, liquid-impermeable pouch, itself packaged inside an impermeable container that is removed at the time the device is used. For example, reference may be made to the document U.S. Pat. No. 4,961,493, which discloses such a device. [0005] Conversely, and according to another known solution, the treating agent is a liquid contained inside of an impermeable pouch, itself contained in a permeable container. When the device is used, the impermeable pouch is broken in order to release the treating agent inside the permeable container. For example, reference may be made to the document U.S. Pat. No. 5,458,244, which discloses such a device. [0006] Nevertheless, triggering the diffusion process is difficult, because it requires multiple handling phases. Moreover, it is necessary to tear a package containing the active components. This step may result in damage to the device. [0007] A device is also known for treating air with a volatile agent contained inside of a permeable container, which offers a satisfactory, stable and continuous diffusion of the treating agent while at the same time optimising the surface available for diffusing the treating agent through the permeable container in order to ultimately reduce the overall space requirement thereof. [0008] However, such devices have the disadvantage of not allowing control over the triggering of the diffusion process. As a matter of fact, the diffusion process becomes operative once the treating agent is inserted into the permeable container. Thus, prior to being installed in the air treatment apparatus for which it is intended, the treating agent has begun to diffuse through the walls of the permeable container. The amount of treating agent for final use within an air treatment apparatus is therefore reduced. [0009] Therefore, the purpose of this invention is to solve the previously described disadvantages. For this purpose, it proposes a cap comprising an interior wall and a bottom forming a reservoir. Preferentially, the interior wall is cylindrical. [0010] Furthermore, the reservoir is sealed off from the outside environment by an inner seal. It may therefore contain an active agent. [0011] According to an alternative embodiment, the interior wall and the bottom have thicknesses defined so as to prevent the treating agent from migrating towards the exterior of the reservoir. [0012] 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. [0013] Thus, 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. In addition, this invention makes it possible to store the products without any risk of reducing the treating power of the treating agent. [0014] According to a first additional characteristic of the invention, the reservoir is closed by an inner seal. [0015] According to a second characteristic of the invention, the device comprises perforating means making it possible to pierce the inner seal. [0016] According to another embodiment, the device comprises a body for supporting the treating agent. [0017] Another characteristic of the invention consists of the fact that the permeable container comprises ribs that clamp tightly around the body. [0018] Alternatively, the cap occupies at least one first and one second position in relation to the permeable container. [0019] According to one alternative of the present invention, the permeable container comprises a wall having an interior face including at least one indexing groove. [0020] It is then preferentially coupled with a boss that is arranged on an exterior wall of the cap and that cooperates with the indexing grooves in order to define various positions of the cap in relation to the permeable container. [0021] According to another embodiment, the permeable container comprises a wall having an interior face including an internal thread that cooperates with a thread made on an exterior wall of the cap in order to screw the cap into the permeable container. [0022] Shifting from the first position to the second position is done by transversely displacing or rotating the cap in relation to the permeable container. [0023] The first position, referred to as the high position, is such that seal of the reservoir is preserved. The second position, referred to as the low position, is such that the seal of the reservoir is broken. [0024] This invention is such that the seal of the reservoir is broken by the perforating means, which may consist of the body comprising a perforator at its upper portion and an additional perforator mounted inside the permeable container.
