A volatile composition dispenser includes a housing having opposing first and second walls that are joined along their peripheries to one another. The first wall has an aperture and the second wall has a plurality of apertures. Within the housing, rests a volatile composition cartridge and a gap, which exists between the cartridge and a bottom surface of the housing, wherein said bottom surface is formed from a joinder of a base portion of one or both of the first and second walls, and wherein, upon activation, the exposure percentage of the dispenser is from about 40% to about 90%; wherein at least about 60% of the total surface area of the plurality of apertures results from individual apertures of said plurality that each have an area of at least 30 mm.sup.2 and an aspect ratio of at least about 1:2. Dispenser of a similar housing, cartridge, and gap when is activated by a user and thirty days after said activation, exhibits about 70% to 90% weight loss of said volatile composition of a partially exposed membrane of a fully exposed membrane.

Diffuser of an active liquid agent, for the treatment of a fluid environment, be it at the gaseous or liquid state, of the type including a container (1) of the active agent, closed by grid element apt to maintain in position the active agent and to allow the emanation of fluids of the same, the grid element being covered by a barrier film, peelable at the time of the first use to make operative the grid element, wherein the container (1) is closed by a single multilayer film (2, 3a, 3b) including at least one external barrier layer (3a) and at least another inner sealing layer (2) apt to maintain in position the active agent and to form the grid element, at the time of the first use of the container, following the simultaneous removal of the barrier film and of predefined portions of the sealing layer.

The invention described presents a device and the method for obtaining the constituent structures to generate a fragrance supply assembly by means of the absorption of the fragrance in a polymer which, when exposed to an environment, disseminates the fragrance over time within the surrounding environment where said output is gradual. Additionally, the constituent materials of the device are biodegradable.

The specification describes the device and the method for preparing the components and the assembly which allow to aromatize for longer periods of time than the devices that are currently on the market, and without the need to use electrical elements for the release of the fragrance in the desired space with a greater amount of aroma and controlled dosage.

The present disclosure makes it possible to fill a fragrance-holding structure with a liquid fragrance more easily and more appropriately. Provided is a fragrance-filling structure (100) including: an accommodating portion (110) which accommodates a fragrance-holding structure; a fragrance-guiding portion (120) which includes an inclined surface that converges on a fragrance pool and guides a liquid fragrance poured from an outside onto the inclined surface to the fragrance pool; and a first impregnated body (130) which includes one end that enters the fragrance-holding structure and provides the liquid fragrance accumulated in the fragrance pool into the fragrance-holding structure using a capillary phenomenon.

A disinfectant device including a pouch, the pouch including a first layer of material coupled to a second layer of material and defining a compartment therebetween. At least one dry reactant is retained within the compartment, the at least one dry reactant producing chlorine dioxide gas when exposed to water. A wick is at least partially disposed within the compartment. At least one from the group consisting of the first layer of material and the second layer of material define an array of ports along a periphery of the pouch and an array of fluid conduits, the array of fluid conduits being proximal to the array of ports, offset from the array of ports, in fluid communication with the wick, the compartment, and the array of ports.

Various fragrance dispensers are disclosed. The fragrance dispenser can include a core unit that has a connection unit and a control unit. The fragrance dispenser can include a cartridge that is configured to engage with the core unit. The cartridge can include an impeller and a fragrant material. The fragrance dispenser can have a motor that drives the impeller, thereby dispersing the fragrance. The cartridge can be configured to disengage from the connection unit, such as when the cartridge reaches a depleted state.

The present disclosure relates to the field of perfumery. In particular, the present disclosure provides fragrance dispensing emanating substrate and related methods for dispensing fragrance oil or liquid fragrance material into an ambient environment.

An exemplary nasal inhaler band is fitted on the upper lip below the nasal openings of a user. The device provides minimal restriction of ambient airflow into the nostrils during inhalation, while also providing a flow of beneficial vapors into such airflow. A main body of the device has an outer layer adapted to hold vapor-releasing solids, liquids or gels. The outer layer is air-permeable and absorbent. The main body also has a base layer contacting the upper lip. The base layer is impermeable, so that volatile solids, liquids or gels do not come into contact with the user's skin. The main body is held in position in contact with the nose and upper lip by elastic straps extending back from ends of the main body to wrap around the user's ears.

A device and method for diffusing volatile substances which obtains the energy required for the autonomous operation thereof from one or more photovoltaic cells. The activation periods and switch-on frequency of the emission means are determined adaptively by an electronic controller depending on the light conditions, thereby maximizing the time in which the device diffuses the volatile substance without compromising its autonomy.

The device (100) comprises a container (200) for containing a fragrance (300) having at least one opening (450), an absorbing element (500) with a first portion (510) to be received within the container (200) continuously in direct contact with the fragrance (300) and with a second portion (520) at least partially outside the container (200) arranged through the opening (450), and a cover (600) that can be made at least partially of an absorbing material, which covers, in at least a substantially fluid-tight and impermeable manner, and at least partially, the second portion (520) of the absorbing element (500).
