[0004]
(Detailed description)
The device according to the invention is a deodorizing and / or fragrance adding device. "Deodorizing and / or adding fragrance" means releasing a fragrance that deodorizes by imparting a fragrance to the surroundings or masking offensive odor. The apparatus includes a container containing scented particles that release a fragrance outside the container.
[0005]
container:
The device according to and used in the present invention comprises a container. The container may be a flexible odor bag, but is preferably substantially a rigid container made of a plastic such as polyethylene or polypropylene. Indeed, by using a substantially rigid container, for example, due to the vibration of a washing machine, or the flow of water in the washing machine or in the shower, the scented particles can move freely within the container and release the perfume. To ensure that the duration and continuity of the perfume release is improved. Also, conventional deodorizers use cardboard or paper, whereas the use of plastic ensures that the container can be used under humid conditions. The use of plastic also ensures that the container does not degrade when exposed to the wide range of temperatures encountered in many ambient environments where the device can be used, such as in a washing machine. Equipment that uses paper or cardboard cannot withstand exposure to warm temperatures.
[0006]
The container must ensure that the fragrance released by the particles can diffuse outwards. Thus, the container may be made of a perfume permeable material, such as, for example, LDPE. However, in its preferred embodiment, the container is made of any plastic, and because the perfume transfer through the substance is slower and more difficult to control, the container is made of all plastics and contains less than all the smaller perfume particles contained. Includes small holes. In one advantageous embodiment, the holes of the container are not all the same size. In fact, pores of different dimensions have different functions: small pores have a dominant role in the release of perfume, while large pores make the wetted device quickly enough when used in a moist ambient environment. Required to dry. Fast drying of the interior of the device is desirable to maintain the efficiency of the device in releasing perfume.
Although the container is closed in that no particles are released, in a particularly advantageous implementation the container is openable and reclosable so that used particles can be discarded and replaced with new particles .
[0007]
Scented particles:
The particles to be placed in the container are scented particles that gradually release the fragrance over a long period of time. Particles suitable for use herein may consist of polymers, or clay, or porous rock or stone, such as pumice, silica or silicate.
However, particularly preferred for use herein are PCT International Patent No. 9947182, British Patent No. 1,589,201, US Patent No. 35,505,432, and US Patent No. 4,247,498. And U.S. Pat.

The perfume substance within the polymer preferably has a calculated log P in the range of about 3 to about 8, where P is the partition coefficient of the active or bioactive substance between n-octanol and water.
[0009]
The fragrance component preferably has a boiling point of 250 ° C. A number of data have been reported for the log P values of a number of perfume ingredients; for example, the Pomona 92 database marketed by Daylight Chemical Information Systems (Irvine, CA) (Irvine, Calif.) Contains numerous data with citations of the original literature. Has been described. However, logP values are most easily calculated by the "CLOGP" program available from Daylight CIS. This program also lists experimental logP values as available in the Pomona92 database. “Calculated logP11” (ClogP) is determined by the fragment approach of Hansch and Leo (C. Hansch, P.G. Sammens, JB Taylor). And Ramsden, eds., CA Ramsden, eds., A. Leo, Comprehensive Medicinal Chemistry, No. 4, p. 295 (1990), incorporated herein by reference. )checking). This fractionation method takes into account the number and type of atoms, the connectivity of the atoms, and the chemical bonds based on the chemical structure of each perfume component. This ClogP value is the most reliable and widely used to evaluate such physicochemical properties, and is preferably an alternative to the experimental logP value in selecting perfume ingredients effective in the present invention. Used for
[0010]
Preferably, the non-persistent perfume ingredients minimized in the present invention have a boiling point of less than about 250 ° C or a ClogP of less than about 3.0, or both a boiling point of less than about 250 ° C and a ClogP of less than about 3.0. Things. The following table shows some non-limiting examples of non-persistent perfume ingredients.

[0014]
In a preferred embodiment herein, when the particles are made of plastic, water is not guaranteed to penetrate the particles whenever present, but is protected until the perfume components present in the particles are released. In addition, the use of plastic ensures that the particles do not degrade when the device is exposed to warm temperatures. Thus, the device can be used over a wide range of temperatures.
The particles herein are preferably substantially spherical, as opposed to rods, or square or square blocks. Indeed, in the case of a sphere, the particles have an improved mobility in the device, so that a fresh and clean surface of the particles is exposed over a long period of time. Conversely, if mobility is limited, the same surface of the particles can be exposed, solidified, and clogged over time. Furthermore, the spherical shape, which combines that the particles are preferably made of plastic, i.e. hydrophobic, flows out of the surface of the particles in the presence of water droplets, contributing to the rapid drying of the particles and thus to wet conditions. Releases perfume more effectively after exposure.
[0015]
The perfume load of the particles can be varied over a wide range, depending on the specific requirements of a particular device. In fact, in small devices, the total particle amount tends to be low, and thus the perfume load of each particle tends to be increased to compensate for the low number of particles present. Conversely, in larger devices, there are more particles and the particles tend to provide a lower perfume load. The particles herein carry typically 2% to 25% by weight of perfume, the total weight of the particles being represented by 20 grams to 75 grams.
Perfume particles suitable for use herein are commercially available from International Flavors and Fragrances (Polyiff) under the trade name Polyiff.
[0016]
The population of particles in a given container may be substantially uniform in perfume content, but it is attractive to have different populations. In fact, certain particles, including certain flavors, may be manufactured in batch processing into a uniform population, and then different populations may be mixed in innumerable variations, making it economically feasible for flavor selection and function. Provides attractive flexibility. In fact, perfumes can be used to additionally provide disinfection and / or antimicrobial benefits.
The population of particles in a given container is substantially uniform in size, which is preferred compared to different populations. In fact, a uniform population in size ensures that in spherical particles there is minimal contact between the particles and surface damage and / or friction is reduced. Also, the rate of perfume release is reduced, and the danger of particle compaction that hinders free rotation of the particles, which ultimately prevents prolonged and gradual release of perfume, is substantially reduced. The container may also be divided into several partitions, each containing a particular population of particles. The population of particles in a given container is preferably different from the population of the other compartments.
[0017]
Preferably, the particles in the container should account for between 5% and 95%, most preferably between 20% and 80% of the contents of the container or each partition. In fact, within this range, there are too many particles to increase the perfume load of the device, the amount of particles desired to be as large as possible, and to improve the sustainability and continuity of the perfume release. A compromise can then be made with the mobility of the particles in the container, which at some point hinders.
