Description

DETAILED DESCRIPTION OF THE INVENTION                      Products that result in the release of volatile substances                                Field of the invention   The present invention relates to products for providing the release of volatile substances, in particular the release of insect repellents For providing portable and disposable products.                                Background of the Invention   Personally used insect repellents or insect repellents have historically been released in a variety of different ways. Have been. For example, it can be sprayed or rubbed on human skin and It may be sprayed on nearby surroundings and / or sprayed on human clothing. Insect repellent The liquid is typically vaporized to release steam from the human body that repels beetles .   An absorbent substrate, made in the form of a patch, filled with a volatile solution of insect repellent, Used to attach to clothes. Typically, patches containing volatile solutions are Must be placed in a container to prevent volatilization of the solution before application of the patch . US Patent Application 08 / 369,0, filed January 5, 1995, in the name of Cook et al. 68 “Containers for inserting and applying insect repellent patches” include a package impregnated with insect repellent. A container for placing a stitch is disclosed. The disclosed container allows the user to: The patch can be applied to a target surface without touching the patch.   Such patches provide a barrier between the surface and the target surface, such as the user's clothing. -Substances. Use a larger volume of volatile solution for the barrier material And provide longer lasting protection from insects. But the amount of solution As the volume increases, some of the solution leaks out of the substrate in a liquid state and It appears that it can be absorbed or carried from a finger into a person's eyes or mouth . Therefore, during a given period, given from the surface area of a given product and to the product first For a given volume of liquid removed, the volume of solution that can be released in the form of a vapor depends on the user's skin Limited by the need to prevent skin from contacting volatile solutions.   Accordingly, it is an object of the present invention to provide for the release of volatiles such as liquid insect repellents. To It is to provide portable and disposable products for.   Another object of the present invention is to provide a barrier layer, a porous cover layer, and a volatile liquid insect repellent. A product having a substrate impregnated with a barrier layer and at least a portion of the substrate. And a material arranged in the middle of the porous cover layer.                               Overview of the present invention   The present invention provides controlled release of volatile substances, such as insect repellents, from a substrate. Includes disposable and portable products for providing.   The present invention relates to a product supported substrate for containing and releasing volatile liquid substances, And a breakable container supported by the product. Volatile in the destructible container Liquid substances. The container is destroyed by the user and volatiles It is poured on quality. In one aspect, the container is pressurized against the container, e.g., between the thumb and forefinger. And destroyed by rupture. In another aspect, the product comprises a container. A piercing element for breaking may be provided.   The substrate may include a fiber substrate. In one aspect, the substrate is associated with the volatile liquid material. And fibers that are non-absorbable. The fibers are formed of a polyolefin material sell. In one embodiment, the substrate may contain furrow fibers having furrows on the outside.   In one aspect of the invention, the product contains a barrier layer and a porous cover layer. The The product may also be used to bond the product to a target surface, such as a user's clothing. A fixture may be provided. The porous cover layer has at least about 10 percent, and Open plastic having preferably at least about 20 percent non-open area Contains a film.                             BRIEF DESCRIPTION OF THE FIGURES   This specification concludes with the claims particularly pointing out and distinctly claiming the invention.
