GAS LIGHTER EQUIPPED WITH DISPOSABLE RAZOR
BACKG--OII D OF THE INVI-NHON
This invention relates to a gas lighter equipped with a disposable razor, and, in particular, to a type of gas lighter, the body part of which has an L-shaped recess to which a removable housing is fixed which housing forms a compartment containing a disposable razor blade assembly therein and is also so shaped as to be used as a handle of the razor during shaving. In general, coventional disposable razors may be divided into two types ; one type is that composed of two separated elements, that is, a handle which is not discarded but used continuously and a disposable razor blade assembly which can be interchangeably fitted to the head of the handle, the other being the type where the handle and the razor blade assembly are so formed in a single body that the handle and the razor blade assembly are to be discarded at the same time after use.
The separated type is suitable for home use and has economical merits in that the handle, which is comparatively more expensive than the razor blade assembly, may be saved for continued use by replacing only the used disposable razor blade assembly with a new one after it has been used. However, in consideration that a disposable separated razor assembly of this type must usually be carried in a certain separate package or case, it is somewhat inconvenient, unhandy or bulky to carry around on one's person if one wants to conveniently provide oneself with the razor at most times in one's jacket, shirt or trousers pocket.
On the contrary, the single body type is so formed whereby its handle is made of comparatively less expensive material than that of the separated type so that it may be said to be more advantageous economically than the separated type when it is used for the purpose of one time only use.
However, the single body type has some disavantages in that the
SUBSTITUTE SHEET
handle and the razor blade assembly must be discarded simultaneously after use, therefore, even though the manufactruing cost of this type razor is less expensive than that of the separated type razor, it is resource consumptive and is still inconvenient, unhandy or bulky to carry around on one's person at most times in one's jacket, shirt or trousers pocket and is unfavorable in view of environmental protection.
SO-flfflRY OF THE INVENTION
The present invention is intended to provide a gas lighter equipped with a disposable razor blade assembly, wherein a part of the gas lighter's body is so shaped as to be suitable to fix a removable housing which contains a disposable razor blade assembly therein and which housing is used as handle of the razor in shaving wherein one need not buy the comparatively more expensive handle and one can increase the portability of the razor at most times since the razor blade assembly can be contained inside the housing whose shape is coincidental with the recess of the gas lighter.

DETALLED DESCRIPπON OF IBE INVENπON As shown in Fig. 1, the gas lighter equipped with a disposable
SUBSTITUTE SHEE
razor assembly according to the present invention is characterised in that said gas lighter comprises :
(a) a gas lighter body (10) comprising an elongated casing (7) having a longitudinal axis, an outer surface having an L-shaped recess (5) formed along with said longitudinal axis and a conventional igniting means (1) at one end of said elongated casing ; and
(b) a housing (28) which has a longitudinal hollow compartment (29) to keep a conventional disposable razor blade assembly (17) therein, a longitudinal opening (30) through which the disposable razor blade assembly (17) can be inserted and removed, a connecting means (26) so formed on the upper end of the brim of said longitudinal opening (30) that said connecting means enables the housing to be easily connected with or removed from the back side of the razor blade assembly (17) by virtue of such connecting means' T-shape, and whereby said housing (28) can be used as a handle of the razor during shaving, and a fixing means (22) so formed on the brim of longitudinal direction as to fix or easily remove said housing (28) with said longitudinal recess (5) of the lighter.
The gas lighter equipped with the disposable razor according to the present invention can further comprise a conventional disposable razor blade, the razor blade assembly of which is kept contained in said compartment of the housing at most times but is taken out and assembled to form a T-shape be attached to the housing handle and used as a razor in shaving. Said conventional disposable razor blade assembly, as shown in Fig. 1 and Fig. 2, may consist of a front panel (15), a back panel (11) and one or two blades (13) so inserted between said front panel and back panel and arranged in a slanted position so as to expose only the cutting edge of blade outwardly therefrom. The back panel (11) of the rezor blade assembly may comprise on its surface a longitudinal reinforcing support (20) and one or more protrusions (19) which can be matched with said connecting means (26)
SUBSTIT
formed on the upper end of the brim of said housing whereby said razor blade assembly is connected with said housing to from a T-shape and thereby assume its proper configuration and function as a shaving razor device. As shown in Fig. 1, the peripheral edge of said recess of the gas lighter has a low upright wall (6) in order to removably match and fix the fixing means (22) formed on brim of the opening (30) to said L-shaped recess (5) of the lighter. Said low upright wall (6) of the recess (5) and said fixing means (22) of said housing can fix and attach to each other by virtue of the elasticity of the material to form a connection between themselves, or can be fitted by virtue of tight friction between these two components, or, as shown in Fig. 6, can be connected by sliding onto rails (31) (32) which have slanted sections in the direction parallel to the longitudinal axis so as not to permit the housing to separate easily from the L-shaped lighter body.
In order to keep the razor blade assembly fixed and contained in the hollow compartment (29) of the housing (28), one side of the connecting means (22) of the housing (28) may have one or more small protrusions (24) which correspond to the holes (18) formed on the front palel (15) of the razor blade assembly (17).
Fig. 4 (a)(b) show the perspective views of the gas lighter having different housing shapes respectively. These teach that the shape of the housing of the invention can be altered arbitrarily without changing the spirit and scope of the invention so long as it satisfies its own function according to the present invention, that is, keeping the disposable razor blade assembly at most times contained within the body of the conventional gas lighter and being used as a handle of the razor in shaving.
Fig. 5 and Fig. 6 show another embodiment of the subject disposable razor blade assembly (17) and two varieties of the connecting means (26) corresponding to fit the shape of the back panel of the razor blade assembly (17).
SUB
In Fig. 5, the housing has a flat aperture (33) perpendicular to the longitudinal axis at one end thereof and an oblong Ω-shaped hook (34) which is so inserted in said flat aperture (33) in such a way that both its outwardly hooked ends (35) are exposed outwardly. Said oblong Ω-shaped hook can be inserted in and removed from said flat aperture (33) and this construction can help to increase the productivity of the housing by virtue of the design of the invention.
Figs. 5 and 6 also teach that the connecting means formed at one end of the housing (28) should be construed to be changeable into other forms or shapes according to the form or shape of the back panel of the conventional disposable razor blade assembly (17).
From the present invention described above a gas lighter equipped with a disposable razor blade assembly is provided, wherein a part of the gas lighter's body is so shaped as to be suitable to fix a removable housing which, on one hand, keeps and contains a disposable razor blade assembly therein and which is, on the other hand, also used as a handle of the razor in shaving so as to enhance the convenience and portability of the razor at most times and can aid in preventing environmental pollution.
