DESCRIPTION:
BRIEF SUMMARY
This invention relates to a comb for use in hairstyling operations which involve the application of liquids, particularly viscous liquids, to the hair.
Conventionally gels, dies, conditioners and the like are dispensed onto the palm of the hand and rubbed into the hair before combing it. This is obviously a messy and inconvenient operation for the hairdresser. Highlighting has been carried out by applying streaks of highlighting gel directly from its container before combine the hair. Again this is an operation in which the hairdresser is likely to soil his hands and it is difficult to control the amount and therefore the spread of the gel applied.
GB-A-444,008 and GB-A-553,912 each disclose combs specially designed to retain viscous liquids in reservoirs between or formed in the teeth. These combs have the advantage that sufficient quantities of a treatment liquid can be retained by the comb to avoid continually dipping the comb, but because the reservoirs can only be charged by dipping the whole comb the liquid is present over the whole length of the comb and not only at selected positions along its length. Too much liquid will be present and these combs are not suitable for the application of highlighting liquids which are to be confined to discrete streaks through the hair.
Avoidance of wetting the whole comb and confining liquid to reservoirs between or in the teeth is aimed at by U.S. Pat. No. 4,566,472. The comb is laid on a template which charges only well formations in the teeth. Clearly this is a time consuming and not particularly easy operation.
U.S. Pat. No. 5,024,243 and U.S. Pat. No. 5,482,058 exemplify prior art proposals for liquid-applicator combs in which the hollow interior of the root of the comb communicates with spaces between adjacent teeth by means of narrow side or capillary passages. Because very little liquid will be exposed at the open end of each of these passages in order to apply the liquid evenly the operator must maintain a carefully controlled pressure to force liquid out of the passages at the appropriate rate.
A principal object of the present invention is to improve upon prior art proposals by providing a comb which combines advantages of previously known combs while at the same time being easier to use and more reliable in its operation. It is another object of the invention to achieve this with a comb of simple construction which is economical to manufacture and will remain reliable in use.
In accordance with the invention a hairstyling comb comprises a hollow root or stem communicable with a reservoir of a viscous liquid to be applied to the hair, discrete passageways spaced along the length of the root or stem whereby its interior opens to discrete locations near the junctions between respective pairs of teeth of the comb, and concavities of the root or stem opening generally laterally of the comb, each conmunuicating with a respective one of said passageways and having a relatively greater cross-sectional area.
In preferred constructions one end of the stem is closed and the other end is adapted for releasable connection to said reservoir, the latter serving also as a handle for the comb when attached to the stem.
Plunger or trigger means may be associated with the reservoir whereby its interior may be pressurised to expel the liquid into the stem, and the plunger or trigger may be positioned so that the forefinger of a hand holding the reservoir may be used to depress the plunger or trigger.
Alternatively the stem may have an open end which is telescopically received in a tubular formation of the reservoir, the stem having limited movement relative to the reservoir between a position in which communication of the interior of the stem with the interior of the reservoir is closed off and a position in which a passageway is opened for the flow of fluid from the interior of the reservoir to the interior of the stem.
Each concavity is preferably formed in root portions of a respective pair of adjacent teeth and the teeth of each pair in which a concavity is formed may
