Definitions

• a hairdresser's apparatus used to streak hair.
• the present patent application for utility model relates to a hairdresser's apparatus used to streak hair.
• streaks consist in hair locks that are selectively given a different color, either lighter or darker, with respect to the base color of hair.
• said streaks are made by applying the desired color on a hair lock and wrapping the lock inside a piece of tinfoil.
• a piece of tinfoil is used to wrap the hair lock completely, assuming a substantially cylindrical shape.
• Said foiled pieces are removed when dye has definitely set on hair locks.
• the hairdresser is forced to repeatedly open the foiled pieces in order to make sure that each hair lock has actually achieved the desired color requested by the user.
• the holder of the present patent application has developed and patented a different technique to streak hair.
• each hair lock that was selectively dyed was enclosed (and consequently protected) inside a sort of case made of semi-rigid transparent plastic material.
• the case claimed in the aforementioned patent is formed of two rectangular sheets of transparent plastic material, having a narrow elongated shape and adapted to longitudinally enclose a hair lock after applying the desired dye.
• Each of said cases is very easy to operate and is characterized by the additional advantage that transparency allows the hairdresser to check the coloring level of the hair lock in real time.
• one of the transversal borders of the upper transparent sheet is hinged to the corresponding transversal border of the lower sheet in such manner that the two sheets are configured as two semi-shells adapted to close and open as the valves of a shell.
• one of the two sheets is provided on the internal side with a metal plate and the other one is provided in perfectly corresponding position with a small magnet adapted to firmly adhere onto said plate.
• the purpose of the present invention is to overcome the structural and functional limitations of the cases for hair locks claimed in the aforementioned patent. More precisely, the purpose of the present invention is to provide cases made of transparent plastic material having a lean, inexpensive structure, and especially adapted to be brought and maintained in "closed" position without making use - unlike the cases of the prior art - of external connection and fixing means (reference is made to said magnetic plates).
• FIG. 1 is an axonometric view of the two semi-shells, before coupling, which form the first part of the apparatus of the invention
• FIG. 2 is an axonometric view of the semi-shells of Fig. 1 , which are firmly coupled one inside the other one;
• FIG. 3 is an axonometric view of the second part of the apparatus of the invention in non-working position
• FIG. 4 is an axonometric view of the part of Fig. 3 in working position;
• - Fig. 5 is an axonometric view of an additional part of the apparatus of the invention;
• FIG. 6 is an axonometric view of the operating modes of the part of Fig. 5;
• Fig. 7 is an axonometric view of a semi-shell to be used alternatively to one of the semi-shells shown in Fig. 1 .
• the first part of the apparatus of the invention consists in a first case (A1 ), formed in turn of two identical semi-shells (10, 10') made of semi-rigid transparent plastic material, which are mutually coupled.
• each of said semi-shells (10, 10') is provided with a central flat section, having a substantially rectangular shape, which is provided on the lateral borders with two identical tubular sections (1 1 , 12/1 1 ', 12') having a substantially C-shaped section and concavity facing towards the center of the corresponding semi-shell.
• distance (x-x) between each opposite pair of said tubular sections (1 1 , 12/1 1 ', 12') measured in the maximum convexity point is significantly higher than distance (y-y) between the free longitudinal borders (1 10, 120/1 10', 120') of the same pair of tubular sections (1 1 , 12/1 1 ', 12')
• Both semi-shells (10, 10') have intrinsic structural elasticity that allows them - when undergoing a suitable stress - to suffer significant deformation, and also automatically recover their "natural" shape as soon as said deforming stress has ceased.
• said semi-shells are identified as first semi-shell (10), being the lower semi-shell, and second semi-shell
• the first semi-shell (10) is adapted to act as support for the hair lock (C) already treated with lighter dye, whereas the second semi-shell
• the coupling of said semi-shells (10, 1 1 ) can be simply obtained by lowering the second semi-shell (10') above the first semi-shell (10).
• Such an insertion can be only obtained by means of said elastic deformation of the two semi-shells (10, 10') and only by exerting an energetic pressure of the second semi-shell (10') on the first semi-shell (10). These two conditions favor a basically "snap-fit" between said two semi-shells (10, 10').
• the inlet section of the first semi-shell (10) is considerably widened, allowing the second semi-shell (10') to exactly penetrate inside it, in such a condition that its central flat section is brought against said central flat section of the first semi-shell
• tubular sections (1 1 ', 12') are inserted inside tubular sections (1 1 , 12) of the first semi-shell (10).
• a tooth or nail (not shown in the attached figures) is provided in external position on at least one of tubular sections (1 1 , 12).
• the first semi-shell (10) being the lower one, is made of non-transparent plastic material, because the dyed hair lock can remain perfectly visible because of the transparency given to the second semi-shell (10').
• the apparatus of the invention also comprises a second case (A2) that is expressly adapted to contain hair locks with considerable length.
• this second case (A2) is provided with the same pair of semi- shells (10, 10') that have been already described with reference to said first case (A1 ).
• the two semi-shells (10, 10') are connected by a thin strap of soft transparent plastic material (20), the ends of which are fixed on the concave side of the two semi-shells (10, 10') in intermediate position between the corresponding opposite pairs of said tubular sections (1 1 , 12 /1 1 ', 12').
• this second case (A2) provides for simultaneously laying a long hair lock (C), which has been already dyed, on the first of the two semi-shells (10) and on said soft plastic strap (20).
• the two semi-shells (10, 10') are facing the corresponding concave sides, in such a condition that said tubular sections (1 1 ', 12') of the second semi-shell (10') embrace from outside the corresponding tubular sections (1 1 , 12) of the first semi-shell (10).
• the tubular sections (1 1 ', 12') of the second semi-shell (10') will suffer the spontaneous elastic return as usual, towards the center of the second semi-shell (10'), which is useful to realize coupling from opposite sides of the tubular sections (1 1 , 12) of the first semi-shell (10).
• the apparatus of the invention comprises an additional case (A3) adapted to contain hair locks with considerable length, and also adapted - unlike said second case (A2) - to allow the hairdresser to choose the length according to each specific hair lock.
• said third case (A3) takes advantage of the cooperation of two different parts.
• the first part consists in a specimen of said semi-shell (10) associated with said soft transparent plastic strap (20); it being provided, in particular, that one end of said strap (20) is fixed on the concave side of the first semi-shell (10).
• the second part simply consists in an independent specimen of said second semi-shell (10'), which is not incorporated with said plastic strap (20).
• the hairdresser will lay the hair lock (C) on the plastic strap (20), directing said first semi- shell (10) towards the beginning of the hair lock, as shown in Fig. 5.
• the hairdresser will fold the soft plastic strap (20) towards the first semi-shell (10), thus practically overlapping the two ends of the strap (20).
• the additional operation consists in fixing the two overlapped ends of said strap (20) inside the first semi-shell (10) by means of said independent specimen of the second semi-shell (10').
• Fig. 6 which is a view of the operating condition of the third case (A3)
• coupling between first semi-shell (10) and second semi-shell (10') is preferably obtained according to the same modes illustrated in Fig. 2, by inserting and snap-fitting the second semi-shell (10') inside the first semi-shell (10).
• the third case (A3) provides for the same use and operation mode as the second semi-shell (A2).
• said third case (A3) is characterized by higher versatility since it allows the hairdresser to exactly adjust the length of said soft plastic strap (20) according to the length of the specific hair lock it will contain after folding.
• Such a length adjustment can be easily obtained by the hairdresser by removing the excess section from the free end (L) of said soft plastic strap (20); said "free end” being the end of the strap (20) not fixed on said first semi-shell (10).
• the apparatus of the invention is composed also of a third semi-shell (10") adapted to be used in the first case (A1 ) alternatively to said second semi-shell (10'), being the upper shell.
• said third semi-shell (10") is provided with a structure that is exactly identical to said first (10) and second (10') semi- shell, with the only peculiarity that it is provided with multiple longitudinal openings (30) obtained in the central flat section in intermediate position between said tubular sections (1 1 ", 12").
• Said third semi-shell (10") is adapted to be used inside said first case (A1 ) to streak hair after enclosing a thick hair lock inside said case (A1 ).
• hair dye will be applied directly above said third semi-shell (10") in such manner to deposit dye only on hair locks that can be achieved through said openings (30), and not on hair locks protected by the "solid" surfaces of said third semi-shell (1 0").
