Abstract:
1. A hair and scalp covering shield for use in treating hair and scalp by an agent against parasitical conditions, the shield comprising: a flexible cover presenting a resilient edge region that fits around the hair and scalp of a user, a treatment zone formed between said flexible cover and the scalp of the user; an agent-charging aperture formed in the flexible cover, said aperture comprising a non-return closure member in the form of a series of circumferentially arranged resilient flaps narrowing to a common center from the circumferential edge of a hole through the cover, wherein the closure is openable by urging the flaps out of their common plane; a means for absorbing and releasing a hair and scalp treating agent, wherein said means is situated on the treatment zone side of said aperture; wherein, when in operative use, said flexible cover is formed to collapsibly cover the user's hair and scalp without impairing other head-associated bodily functions; wherein said flexible cover is configured to permit, in response to an exertion of manual pressure, the expelling of the bulk of air from said treatment zone through said aperture after the flexible cover is operatively fitted to the head of the user; wherein said fitting is of adequate tightness to at least substantially limit escape of said agent once the cover is in operative use; wherein said aperture is configured to allow, with the resilient edge of the cover, pressurization of said treatment zone when said treatment zone is charged with said agent; and wherein said agent-absorbing and releasing means is configured to allow distribution of said agent in response to body heat generated inside the treatment zone when the flexible cover is in operative use.
