摘要:
The present invention concerns a moisture-absorbing tablet (10) comprising a compacted composition (11) comprising a desiccant, characterised in that it comprises a solid gel (12) adhered directly to the compacted composition and comprising at least one volatile active substance, at least one gelling agent and optionally at least one curing agent. The present invention also concerns a method for preparing such a moisture-absorbing composition and a device for diffusing a volatile active substance in a homogeneous and non-decreasing manner comprising said tablet.

Devices that provide timed-release of target compounds absorbed by, or otherwise integrated into, an external housing. The external housing absorbs and facilitates volatilization of the released compound. A permeable cover can be employed as a regulating mechanism to control the rate volatilization from the external housing. One or more reservoirs containing target compound can be contained within one or more internal chambers of the external housing. The one or more reservoirs can release the target compound for absorption by the external housing and/or to make contact with one or more other reservoirs so as to compromise the other reservoirs and release target compound within. A wick can e employed in certain embodiments to transfer target compound from the internal chamber to the external housing to be volatilized. Continued or sequential release of target compound to recharged the external housing achieves a zero order release rate from the external housing.

A method for delivering a volatile fluid in a continuous manner, over a period of time and without leakage, to the atmosphere is disclosed. The method includes activating a device by breaching a semi-rigid sheet to release volatile fluid to the atmosphere. The device includes a flexible sheet and a semi-rigid sheet that are sealed along their edges to form a closed pocket or reservoir for containing a volatile fluid. The semi-rigid sheet is sealed on a first side to a flexible sheet and sealed on a second side to a vapor permeable membrane. The semi-rigid sheet contains a volatile fluid in the reservoir during storage, preventing contact of the volatile fluid with the vapor permeable membrane before the device is activated. The semi-rigid sheet has a differential score to guide the bounds of an opening that is formed upon activation. Once activated, the vapor permeable membrane provides continuous emission of a volatile fluid from the device.

An air freshener removably engages with a structure, such as the supporting post of a rear view mirror of a motor vehicle. The air freshener has a rigidifying core defining a central axis, and an outer portion or sleeve contacting the core that is formed from one or more fragrance loaded polymers. Together, the core and outer portion are shaped to surround a first axis perpendicular to the central axis. The ends of the air freshener are juxtaposed generally opposite one another in closed configuration, and the arm portions of the air freshener flex in directions substantially parallel to the first axis to separate the ends to open the air freshener. A breakable strap and/or connectors may be provided to join the ends together. Alternatively, one end of the air freshener may be inserted within a cavity formed in the opposite end of the air freshener.

A fan type debugging apparatus is also disclosed in which the active ingredient impregnated body or mass is disposed in a wind inlet side of the fan type blower and is designed to provide a wind force resistance which in terms of the proportion of current consumption by the motor in the presence of the active ingredient impregnated body or mass to current consumption by the motor in the absence of the active ingredient impregnated body or mass, ranges from 5 to 25 %.

A sustained release pheromone carrier (10) is provided in which once it is secured to a branch or other support, the likelihood of falling off is significantly reduced, and which is capable of being quickly attached to a small or large branch. The sustained release pheromone carrier comprises a first sheet part (1) and a second sheet part (2) which are provided by bending a single polymer sheet so that they are arranged in a face-to-face manner, the sheet parts each having an engaging hole (7, 8) therethrough; a bend part (3s) located between the sheet parts; at least one sex pheromone substance that is carried on at least a part of the sheet parts; and slits (4) each extending from the bend part to the engaging hole in each one of the sheet parts. This carrier can be secured to the rod-shaped support by guiding the rod-shaped support to the engaging holes via the slits and engaging with the holes.
摘要:
The invention relates to a gel-like material in a planar form for treating ambient air. Said gel-like material contains a matrix comprising crosslinked polymers which are provided with hydrophilic groups and to which volatile active substances are adsorbed. The matrix forms a spongy structure along with said volatile active substances, from which the active substances are slowly and steadily released so as to react with and eliminate malodorous or harmful substances contained in the air. The polymer matrix comprises at least two different polymers which form an interpenetrating network, preferably after being crosslinked.
