The present invention relates to a visual indicating device and an article for controlling odors, in particular foot, garbage, basement, cooking, pet, tobacco, feces and urine odors. The article comprises a visual indicating agent that is color sensitive to the odor, and optionally, an odor absorbing agent. The visual indicating agent changes color when the article has been exposed to a sufficient amount of odor to saturate the article. The indicating agent may be applied in differing concentrations to two or more zones so as to indicate to a user of the article how much of the odor absorbing capacity has been used, or conversely, how much of the odor absorbing capacity remains. Suitable visual indicating agents that change color in response to odors are also described. The article for controlling odors may be a disposable odor absorbing sheet, air freshening product, diaper, undergarment pad, face mask, air filtration device, sanitary napkin, tampon, panty shield or incontinence pad.

A novel air freshener for use in a bathroom is disclosed and comprises a sending unit that is mounted in the tank of a toiler assembly, and a remote dispenser comprised of housing and a base and that is preferably mounted onto the ceiling of the bathroom. The sending unit includes level sensing module that generates a signal whenever the toilet is, flushed (thereby lowering the water level in the toilet tank) and the same signal is received by the remote dispenser. The remote dispenser then reacts by activating for a set period of time a spray pump and drive motor which causes the housing of the remote dispenser to simultaneously rotate while an odor control chemistry is atomized through a spray nozzle located on the housing of the remote dispenser, thereby broadcasting an effective measure of odor control chemistry into the bathroom space.

The present invention relates to disposable absorbent articles comprising skin health and odor control additives for the treatment and prevention of skin irritation. The skin health treatment additive comprises an oil soluble wax that forms a tight lattice to protect the skin, and vitamins, lipids and triglycerides to protect and replenish the skin. Such disposable absorbent articles of the present invention are especially advantageous for the treatment and skin breakdown leading to partial full thickness wounds or pressure ulcers.

Provided is a method for realizing a multimedia real-time dynamic fresh-air running machine. According to the method, a digital airflow and odor control method is organically integrated with an electric running machine. The multimedia real-time dynamic fresh-air running machine has the functions of a traditional electric running machine, can also provide a clean, fresh and fragrant running environment for a runner, especially, simulated real-time dynamic fresh air can be generated so that the runner can experience the real feeling that flow air blows in the face and crosses the shoulder during running in an indoor environment or a virtual scene, and the runner even can smell the fragrance of flowers and plants along the running environment.

A technique for incorporating odor control agent particles into an absorbent article is provided. More specifically, the odor control particles are “homogenously” distributed (e.g., in a substantially uniform manner) within an airformed fiber matrix of an absorbent core of an absorbent article. An absorbent core containing such a homogeneously distributed odor control particles may possess a greater surface area for contacting malodorous compounds, thereby increasing the likelihood of odor reduction.

An odor control fragrant additive comprises compacted pellets or granules infiltrated with fragrant oil. Cellulosic material, activated carbon and binder are mixed together and compacted to produce compacted pellets or granules. The cellulosic material preferably is peat moss, which swells up during absorption of fragrant oil and acts as fragrant oil storage. Fragrant oil is delivered to activated carbon that has large surface area, which evaporates the fragrance oil to release steady fragrance output. Thus, the activated carbon, which evaporates fragrance provides steady release of fragrance in the surrounding environment of fragrant compacted pellets or granules for a period of several months without overpowering the environment with excess fragrance. The fragrant compacted pellets or granules may be used to suppress malodor from trashcans or litter boxes and may provide stand-alone additions to drawers and cabinets, emitting pleasant fragrance.

An odor control substrate that contains a plurality of fibers oriented in the z-direction is provided. At least some of the fibers contain portions that are exposed on an outer surface of the substrate. An odor control coating is applied to the substrate so that a majority of the coating resides on the exposed portions. As a result, the odor control substrate may retain certain of its beneficial properties even after being applied with the odor control coating, such as good extensibility, absorbency, etc.

Described are fiber materials having improved malodor scavenger properties and a process for the manufacture of said materials. In particular, described are fiber materials usable in the manufacture of disposable or washable diapers, incontinent products, sanitary napkins and other such hygiene and personal care articles with improved malodor scavenger properties, and to methods of manufacturing such materials. It has been found that the incorporation of, especially nanosized, metal particles and/or a cyclodextrin material into fibers creates a “reactive” material having excellent malodor scavenging properties. More specifically, it has been found that the presence of nanosized metal or metal alloy particles and/or a cyclodextrin material in a fiber material, preferably a synthetic polymer material and more preferably a synthetic thermoplastic polymer fiber material leads to fiber materials or nonwovens having odor-controlling properties. The fiber material especially is useful in the manufacture of hygienic products like disposable diapers.
