BEST MODE
Mode for Invention
[0036] A decorative plate formed on a lid of a compact case
according to the present invention will be described as below with
reference to the accompanying drawings.
[0037] FIG. 1 is a perspective view showing a configuration
according to one embodiment of the present invention. FIG. 2 is an
exploded perspective view showing a total configuration according
to one embodiment of the present invention. FIG. 3 is a sectional
view showing a total configuration according to one embodiment of
the present invention.
[0038] Hereinafter, the present invention will be described in
detail.
[0039] The present invention includes a decorative plate formed on
a lid of a compact case opened at a top thereof and includes a case
body 10 accommodating contents, and a case lid 20 hinge-coupled to
one side of the case body 10, wherein a decorative plate recess 22
is formed on an upper surface of the case lid 20 and includes a
decorative plate 30 mounted and bonded onto the decorative plate
recess 22, and the decorative plate 30 includes a transparent plate
base 31, a printing layer 32 printed on a bottom of the transparent
plate base 31, a pigment layer 33 formed by applying a pigment on a
bottom of the printing layer 32, and an adhesive layer 34 formed by
applying an adhesive on a bottom of the pigment layer 33.
[0040] The transparent plate base 31 is formed of a transparent
synthetic resin material, a phrase or picture printed on a bottom
thereof is prevented from being directly exposed to the outside so
as to prevent being peeled or erased, thus an additional
transparent coating is unnecessary, thereby reducing production
costs and allowing long-term use.
[0041] Preferably, the transparent synthetic resin material
includes one selected from the group consisting of acryl resin,
vinyl acetate resin, vinyl acetyl resin, methyl methacyl resin,
polystyrene resin, and celluloid.
[0042] Preferably, a printing layer 32 printed on a bottom of the
transparent plate base 31 may include one selected from the group
consisting of a pad printing, an offset printing, a screen
printing, a transfer printing, and a digital printing.
[0043] The pad printing is a scheme to transfer ink, which is put
on an engraved portion of a corrosion plate, onto the transparent
plate base 31 by using a silicon pad. Because the silicon pad is
used, a printing can be performed on a curved surface as well as a
flat surface.
[0044] The offset printing is a printing scheme for expressing all
of several tens of million colors the same as seen with eyes. The
offset printing is basically formed of four colors, and C.M.Y.K
colors are treated into gradation, thus each of the colors is
printed in one color, form and texture as same as seen with the
eyes. C refers to a blue series, M refers to a red series, Y refers
a yellow series, and K refers a black series.
[0045] The screen printing refers to a printing in a manner that a
web-shape structure of a fabric formed of a silk or a chemical
fiber, and a metal etc. is tightly fastened and used for a screen,
a part to be a non-screen image part is covered by a paper stencil
or a glue material, and ink is applied on the screen, thus the ink
is printed only on a screen image part through the screen.
[0046] The transfer printing refers to a printing in a manner that
a print is performed beforehand on a paper applied thereon with
special glue, namely, on a transfer paper, and the transfer paper
is attached to and peeled from the bottom of the transparent plate
base 31 so as to transfer a pattern and a phrase.
[0047] The digital printing does not require an additional film
because a digital printer is used. To spontaneously perform
printing and coating in the digital printer or to perform an uneven
embossing and special intaglio processing is available.
[0048] In addition, preferably, the digital printing uses at least
one type of ink selected from the group consisting of aqueous dying
ink, aqueous a pigment ink, strong solvent a pigment ink, weak
solvent a pigment ink, mild ink, eco ink, and oil ink.
[0049] In addition, according to the digital printing, an image is
printed in an ink-jet or a laser type, so that the image can be
delicately and clearly to be suitable for a concept of a
product.
[0050] Further, in order to emphasize an image of a specific part
on an entire print surface, it is preferable to use mixed ink
obtained by mixing one of polyester acrylate, epoxy acrylate, and
urethane acrylate with palm oil alkyd resin, nonvolatile oil and a
pigment.
[0051] The palm oil alkyd resin has low unsaturation due to a low
iodine value of about 8 to about 10, thus a dried oxide film is
formed, so that a blockage of a nozzle is prevented. In addition,
by using palm oil alkyd resin having 20,000 to 40,000 of molecular
weight, the gloss and the abrasion resistance of a print surface
applied thereon with the mixed ink can be excellent, and the ink
dries more rapidly, thus a spread-out, a set-off and so forth are
prevented on the applied print surface, thereby implementing a
preferable printing.
[0052] Further, a mixed ink composition contains 10 to 15 wt % of
the palm oil alkyd resin with respect to 100 wt %, so a color of
printed image becomes defected when being under 10 wt % of the palm
oil alkyd resin, and a stain is generated on the applied print
surface due to low drying speed because of high viscosity of the
mixed ink, when being over 10 wt % of the palm oil alkyd resin.
[0053] The pigment layer 33 applied thereon with a pigment is
formed at a bottom of the printing layer 32, such that the printing
layer 32 can stand out more clearly, and the adhesive layer 34 can
be prevented from being seen through the transparent plate, when
the decorative plate 30 is bonded into the decorative plate recess
22 on the lid 20.
[0054] In addition, the pigment uses water soluble baking resin a
pigment, preferably includes at least one from the group consisting
of amino alkyd resin, phenol resin, melamine denatured acryl resin,
and amino resin.
[0055] The amino alkyd resin is a baking a pigment formed of a
mixture of melamine or urea resin and alkyd resin.
[0056] The melamine denatured acryl resin is a pigment formed of a
mixture of melamine resin and thermosetting acryl resin.
[0057] The alkyd resin belongs to polyester resin which is a
polymer material generated by condensation of polyvalent alcohol
and polyvalent acid.
[0058] In addition, the decorative plate 30 is expressed in various
colors by adding a coloring pigment into the pigment, and the
decorative plate 30 is expressed in various colors due to light or
heat by adding luminous a pigment or cyan a pigment, thereby
improving the aesthetic of the decorative plate.
[0059] The adhesive layer 34 formed by applying an adhesive on the
bottom of the pigment layer 33 may use an adhesive using rubber
cement melt in gasoline or polyvinyl acetate-based polymer melt in
thinner as a solution, an adhesive using cyanoacrylate or
bisacrylate which is a liquid state having small molecule at first
and becomes polymer through polymerization after attachment, or a
hot melt adhesive attached by heating and fusing a solid having
high molecule, in which the hot melt adhesive is preferably
polyester-based polymer.
[0060] A decorative plate formed on a lid of a compact case
according to another embodiment of the present invention will be
described with reference to FIG. 4.
[0061] FIG. 4 is a sectional view showing a decorative plate formed
on a lid of a compact case according to another embodiment of the
present invention.
[0062] Hereinafter, the another embodiment of the present invention
uses reference numbers the same as the one embodiment.
[0063] The present invention further includes a metal vacuum
depositing layer 35 between the printing layer 32 and the pigment
layer 33.
[0064] The transparent plate base 31 formed thereon with a printing
layer 32 is put into a vacuum chamber, and a metal is
vacuum-deposited on the printing layer 32 under the high vacuum
condition of 1.times.10.sup.-5 to 1.times.10.sup.-4 torr to form a
metal vacuum depositing layer 35.
[0065] The metal vacuum depositing layer 35 preferably includes at
least one selected from the metal group consisting of Ti, Al, Au,
Ni, Cr, and Cu.
[0066] A decorative plate formed on a lid of a compact case
according to another embodiment of the present invention will be
described with reference to FIG. 5.
[0067] FIG. 5 is a sectional view showing a decorative plate formed
on a lid of a compact case according to still another embodiment of
the present invention.
[0068] Hereinafter, the still another embodiment of the present
invention uses reference numbers the same as the one
embodiment.
[0069] Preferably, a clear coating composition is sprayed on a top
of a transparent plate base 31 so as to form a clear coating layer
36.
[0070] Preferably, the clear coating composition has a
three-dimensional web structure and contains silanol which is an
ionic bonding of silicon and oxygen.
[0071] The clear coating composition containing the silanol is used
to protect an upper surface of the transparent plate base 31 from
dusts, sands, and ultraviolet rays and polish the upper surface of
the transparent plate base 31.
[0072] Because the clear coating composition contains the silanol
(Si--OH), a surface resistance thereof is lower than that of
fluororesin, thus static electricity is prevented, and a pollution
resistance against urban dusts and discharging gas and cleaning
recovery are excellent.
[0073] In addition, ion binding energy between silicon and oxygen
of the silanol (Si--OH) is 101 kcal/mol, which is greater than
ultraviolet energy having 85 kcal/mol, thus the collapse between
molecules due to the ultraviolet rays is prevented, thereby
blocking bleach and discoloration.

[0093] Preferably, in the depositing process S22, the depositing
temperature is 600.degree. C. to 1,300.degree. C.
[0094] Further, in the depositing process S22, it is preferable to
select one from DC sputtering using direct current voltage, RF
sputtering using high frequency, magnetron sputtering using a
magnetic field, and ion beam sputtering.
[0095] A method of producing a decorative plate formed on a lid of
a compact case according to still another embodiment of the present
invention will be described with reference to FIG. 9.
[0096] FIG. 9 is a flowchart showing a method of producing a
decorative plate formed on a lid of a compact case according to
still another embodiment of the present invention.
[0097] The still another embodiment of the present invention is
same as the producing method according to another embodiment,
however, further includes a coating process S24 of forming a clear
coating layer 36 by spraying a clear coating composition on a top
of the transparent plate base 31, between the depositing process
S22 and the adhesive layer process S30.
[0098] Preferably, the clear coating composition has a
three-dimensional web structure and contains silanol which is an
ionic bonding of silicon and oxygen.
[0099] The clear coating composition containing the silanol
(Si--OH) has a surface resistance lower than that of fluororesin or
imitated thin film coating agent, thus static electricity is
prevented, and a pollution resistance against urban dusts and
discharging gas and cleaning recovery are excellent.
[0100] In addition, ion binding energy between silicon and oxygen
in the silanol (Si--OH) is 101 kcal/mol, which is greater than
ultraviolet energy having 85 kcal/mol, thus the collapse between
molecules due to the ultraviolet rays is prevented, thereby
blocking bleach and discoloration.
[0101] The description above is merely an embodiment for the
decorative plate formed on the lid of the compact case and the
method of producing the same, the present invention should not be
construed as limited thereto, and it will be apparent to any one of
ordinary skill in the art in that many different substitutions,
deformations and modifications are available within the scope
without departing from the invention.
