Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The invention relates to cosmetic boxes and more
particularly to a plastic pin for a cosmetic box and its
application, the plastic pin being made of plastic and having the
characteristics of being environmentally friendly, capable of
hingedly fastening two objects together without being damaged or
broken, and improving the quality of produced plastic pins.
2. Description of Related Art
[0002] A conventional cosmetic box 70 is shown in FIG. 5 and
comprises a cover (not numbered) and a base (not numbered)
including a metal hinge 60 for hingedly fastening the cover and the
base together. Lubricating oil 62 is coated on the hinge 60 for
preventing the hinge 60 from being rusted by the air. However, the
lubricating oil 62 may involve a chemical reaction with the air to
form a rust layer 64 on the hinge 60. The rust layer 64 can hinder
the pivotal operation of the hinge 60 when closing or opening the
cosmetic box 70. The hinge 60 may be malfunctioned to jam the
opening or closing of the cosmetic box 70 after a period of time of
use. To the worse, the cosmetic box 70 may be damaged or
broken.
[0003] Thus, the need for improvement still exists.
SUMMARY OF THE INVENTION
[0004] It is therefore one object of the invention to provide a
cosmetic box comprising a cover including a block on an underside,
the block having an axial channel; a base including a groove on one
side, the groove being complimentarily shaped to the block, and two
opposite through apertures, each extending from an outer surface of
the base to either end of the groove; and at least one plastic pin
including two convex portions at two ends respectively, and two
transitional members, each around the convex portion; wherein the
block is disposed in the groove, and the at least one plastic pin
is inserted through one through aperture, the axial channel, and
the other through aperture to pivotally couple the cover and the
base together.
[0005] Preferably, the plastic pin is made of plastic.
[0006] Preferably, the cover includes a central cover element which
is transparent or opaque.
[0007] Preferably, further comprises a frame member on the base,
the frame member includes a central opening as storage.
[0008] Preferably, a plurality of first bossed holes are provided
on a top of the base respectively, and a plurality of hole members
are provided on a bottom of the frame member respectively, and the
first bossed holes are inserted into the hole members.
[0009] Preferably, the cover includes a catch on an underside, the
base includes a second bossed hole, the frame member includes a
through hole on one side, the second bossed hole is inserted
through the through hole to fasten the base and the frame member
together, and the catch is inserted into the second bossed hole to
fasten the cover, the frame member and the base together.
[0010] It is another object of the invention to provide a usage
method of putting a plastic pin to pivotally couple a cover and a
base of a cosmetic box, wherein the plastic pin is a solid cylinder
having two convex portions at two ends respectively, and two
transitional members each around the convex portion, the usage
method comprising the following step: the plastic pin being
inserted through a through aperture of the cover, a channel of the
base so as to pivotally couple the cover and the base of the
cosmetic box together.
[0011] The invention has the following advantages and benefits in
comparison with the conventional art:
[0012] The plastic pin is made of plastic and it can be recycled.
Further, it can reduce the consumption of non-recyclable material
and save cost. Furthermore, it is environmentally friendly.
[0013] The plastic pin is flexible and has two rounded or chamfered
ends. Thus, the plastic pin can decrease friction when it is
inserted through one through aperture, the channel, and the other
through aperture. The cover and the base pivotably secured together
by the pin are prevented from being damaged or broken, thereby
improving the quality of produced plastic pins.
[0014] Finally, the plastic pin is prevented from being rusted.
Thus, it is durable.
