ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a cosmetic pencil cartridge, and more particularly, to a cosmetic pencil cartridge capable of accommodating various cosmetic masses different in size by exchanging a holder for fixing the cosmetic mass; the cosmetic pencil is also provided with; an auxiliary lid capable of not only supporting a leading portion of the cosmetic mass but also molding the leading portion into a beautiful shape without an extra means for supporting and shaping the leading portion of the cosmetic mass when the cosmetic mass is introduced into the cosmetic pencil cartridge.
DESCRIPTION OF THE PRIOR ART
Generally speaking, lipstick, eyebrow pencil, etc. are known as cosmetic pencils. Cosmetic masses contained within the cosmetic pencil, especially lipstick, are manufactured in different shapes and sizes.
Conventionally, in order to manufacture various cosmetic pencils having cosmetic masses in different sizes, cosmetic pencils have been independently designed and manufactured which increases the manufacturing cost of the whole cosmetic pencil.
There is shown in
FIG. 1
one example of conventional cosmetic pencils. As shown, a pencil housing
1
has a cartridge inserted therewithin which includes a cap
2
, a tube member
3
and a holder
4
.
The cap
2
has a guiding hole
5
longitudinally formed therethrough and a guiding groove
8
longitudinally formed on an external surface thereof. The tube member
3
is rotatably mounted around the cap
2
and has a thread
10
formed therein.
The holder
4
of a substantially tubular shape is assembled into the cap
2
in such a way that a protuberance
11
formed on an end of the holder
4
is engaged with the thread
10
of the tube member
3
through the guiding groove
8
. A cosmetic mass
13
is inserted into and seated on an inside of the holder
4
.
However, the conventional cosmetic pencil constructed in this manner has the shortcoming in that, if dimensions of the cosmetic mass are changed, all of the components of the cosmetic pencil have to be newly designed and arranged. That is, in order to manufacture a new cosmetic pencil having a cosmetic mass different in size from old cosmetic mass, many components have to be newly designed and arranged for the new cosmetic pencil, increasing manufacturing cost and consumer price. Further, in accordance with the conventional technique, since the cosmetic pencil finally produced has a diameter depending upon the diameter of the cosmetic mass, the cosmetic pencil does not have a good appearance.
FIG. 6
is a sectional view of a conventional cosmetic pencil, which shows how a cosmetic mass is introduce into the cosmetic pencil. In the illustrated prior art, a cosmetic mass
23
has to be introduced through a hole
25
formed on a rear end of a pencil case
21
, being supported by a cover
24
closely contacted with a leading portion of a cap member
22
. As a result, the cosmetic mass
23
is molded by the cover
24
into a same shape as that of the cover
24
.
Since the prior art cosmetic pencil is constructed in this manner, it has a shortcoming in that it needs separate tools, i.e., the cover, for the introduction of the cosmetic mass into the cap member. Furthermore, the hole of the pencil case has to be covered with, for example, a sticker or the like, whereby the whole manufacturing process becomes more complicated.
On the other hand, in the well-known cartridge type cosmetic pencil, the cosmetic mass is introduced from a leading portion of the cartridge. However, manufacturing this type of cosmetic pencil not only requires modifications of the machining tools as well as a separate means for molding the leading portion of the cosmetic mass but also has a lot of limitations in the manufacturing process.
SUMMARY OF THE INVENTION
It is, therefore, a primary object of the present invention to provide a cosmetic pencil cartridge capable of accommodating various sizes of cosmetic masses by replacing only a holder for fixing the cosmetic mass, without necessitating modifications of other components of the cartridge, thereby lowering the manufacturing cost and allowing a unique size of the cosmetic pencil cartridge.
The above and other objects of the invention are accomplished by providing a cosmetic pencil cartridge provided with a cap member having a guiding hole formed therethrough and a holder movably mounted into the cap member, wherein a stopping wall is formed within a mid portion of the cap member, an enlarged diameter portion being formed in front of the stopping wall, the holder having a pair of hook receiving holes formed through the leading portion of the holder, an auxiliary holder having a mass receiving portion for receiving the cosmetic mass at is one side, and a pair of hooks protruding from the other side of the auxiliary holder, and the pair of hooks being resiliently engaged into the hook receiving holes, respectively.
In accordance with one aspect of the present invention, the cosmetic pencil cartridge is further characterized in that a plurality of protuberant surfaces, each of which has a rectangular shape are formed within the enlarged diameter portion of the cap member, near the stopping wall, and a plurality of sunken surfaces of rectangular shape on each of which a corresponding protuberant surface is seated are formed on the auxiliary holder to thereby allow the hook receiving holes of the holder and the pair of hooks of the auxiliary holder to be exactly guided and engaged with each other.
Accordingly, when a diameter of the cosmetic mass to be used is substantially similar or equal to that of the holder, the cosmetic mass is directly inserted into the holder, and, when the diameter of the cosmetic mass is smaller or larger than that of the holder, the auxiliary holder is additionally assembled with the holder. By this configuration, most components of the cosmetic pencil cartridge have a great level of compatibility between cosmetic masses of different diameter.
In accordance with another aspect of the present invention, the cosmetic pencil cartridge is further characterized in that the cosmetic pencil cartridge has an auxiliary lid having a contact surface at its inner bottom and being combined with the leading portion of the cap member.
The inventive auxiliary lid having a contact surface and covering the leading portion of the cap member enables the cosmetic mass to be introduced from the rear end of the holder, so that the leading portion of the cosmetic mass is made in a same beautiful shape as that of the contact surface by being closely contacted on the contact surface of the auxiliary lid, when the cosmetic mass is fixed to the holder. Then the final packing process can be performed right after the introduction of the cosmetic mass, preventing the cosmetic pencil cartridge from being contaminated with alien material.
