Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of Korean Patent
Application No. 10-2006-0012456, filed on Feb. 9, 2006, in the
Korean Intellectual Property Office, the disclosure of which is
incorporated herein by reference.
BACKGROUND
Field of the Invention
[0002] The present invention relates to a cosmetic case which can
reduce the manufacturing cost by integrally forming a body and a
cover thereof by a single process with a single mold, respectively,
which can easily open and close the cover by one touch, and which
can safely maintain and keep the contents.
[0003] Conventionally, since a body and a cover of a cosmetic case
have been manufactured by using a plurality of parts which are
formed by complex processes which need a plurality of molds, the
manufacturing cost of the molds and the assembling cost of the
parts have been high.
[0004] Further, although some conventional cosmetic cases can be
automatically opened, a sealing structure of a packing portion
making contact with the peripheral portion of the upper end of the
body in which a cosmetic is contained is so vulnerable that the
alcohol component in the cosmetic may be volatilized, thereby
deteriorating the original function of the cosmetic.
SUMMARY OF THE INVENTION
[0005] Accordingly, the present invention has been made to solve
the above-mentioned problems occurring in the prior art, and an
object of the present invention is to provide a cosmetic case which
can reduce the manufacturing cost by integrally forming a body and
a cover thereof by a single process with a single mold,
respectively, and which can safely and firmly seal the cosmetic
case by using the sealing structure of a plate-like annular packing
interposed in the cover making contact with the peripheral portion
of the upper end of the body so that a cosmetic therein is
prevented from being volatilized and the original function of the
cosmetic can be maintained.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] The above and other objects, features and advantages of the
present invention will be more apparent from the following detailed
description taken in conjunction with the accompanying drawings, in
which:
[0007] FIG. 1 is a perspective view for showing a cosmetic case
according to the present invention, with a cover opened;
[0008] FIG. 2 is a cross-sectional view of FIG. 1;
[0009] FIG. 3 is a rear view for showing shaft support portions of
a body and a cover of a cosmetic case according to the present
invention;
[0010] FIG. 4 is a cross-sectional view for showing a cosmetic case
according to the present invention, with a case closed; and
[0011] FIG. 5 is a cross-sectional view for describing the
operation for opening a cover of a cosmetic case according to the
present invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0012] Hereinafter, a preferred embodiment of a leftover
food-treating device according to the present invention will be
described with reference to the accompanying drawings.
[0013] A body 1 and a cover 2 are formed by a single process with
one mold (not shown), respectively. An upper end protruding wall 3
protrudes from a peripheral portion of the upper end of the
peripheral wall 1a forming the body. A space portion 4 is formed on
the front side of the outer peripheral wall of the body. A pressure
applying piece 6, from which an outward locking boss 5 protrudes,
is integrally formed with the body 1.
[0014] Shaft support holes 7 and 7a are formed on the rear side of
the outer peripheral wall of the body 1. Further, a shaft receiving
recess 8 is formed on the rear side of the outer peripheral wall of
the body 1.
[0015] An inner race protrusion 9 protrudes from an inner lower end
portion of the peripheral wall 2a forming the cover 2 so as to
define an inner race groove 10. A resilient plate-like annular
packing 11 is interposed in the inner race groove 10. A downward
support member 12 integrally formed with the peripheral wall 2a of
the cover 2 is formed on the rear side of the cover 2. A shaft
receiving portion 12a is formed at an lower end portion of the
downward support member 12, by forming a shaft pin hole 13a into
which a shaft pin 13 is inserted. A locking piece 15, from which an
inward locking boss 14 protrudes, is integrally formed with the
peripheral wall 2a of the case 2 on the front side of the cover
2.
[0016] A shaft receiving portion 12a formed at a lower end portion
of the downward support member 12 of the cover 2, which is formed
by a single mold, is interposed in a shaft receiving recess 8
formed on the rear side of the outer peripheral wall of the body 2.
The shaft pin hole 13a of the shaft receiving portion 12a is
arranged so as to be side by side with the shaft support holes 7
and 7a formed to both sides of the shaft receiving recess 8, and a
shaft pin 13 is inserted into one of the shaft support holes 7 and
7a and then the shaft pin hole 13a and the other of the shaft
support holes 7 and 7a. Thereafter, by rotating the cover 2 to the
upper side of the body 1, the locking piece 15 formed on the front
side of the cover 2 is moved toward the upper end of the pressure
applying piece 6 formed on the front side of the outer peripheral
wall of the body 1 and thus the inward locking boss 14 inwardly
protruding from the locking piece 15 of the cover 2 inwardly
applies a pressure to the outward locking boss 5 protruding from
the pressure applying piece 6 of the body 2 so that the inward and
outward locking bosses 14 and 5 are engaged with each other and the
plate-like annular packing 11 interposed in the inner race groove
10 of the cover 2 applies a pressure to the upper end protruding
wall 3 formed at the peripheral portion of the upper end of the
body. Therefore, the cover 2 can safely and firmly cover the upper
end of the body 1.
[0017] On the other hand, if a pressure is inwardly applied to the
pressure applying piece 6 of the body 1 to open the cover 2, the
pressure applying piece 6 is urged to the inner side of the space
portion 4 and the inward locking boss 14 of the cover 2, which is
engaged with the outward locking boss 5, is released so that the
cover 2 can be opened softly and freely.
[0018] The cover 2 can be softly and freely opened and closed by
one touch, with a cosmetic received in the body 1. Further, since
the upper end protruding wall of the body 1 is safely and firmly
closed by the resilient plate-like annular packing of wide sealing
area, an alcohol component of the cosmetic can be perfectly
prevented from being volatilized, with the original function of the
cosmetic being safely maintained.
[0019] According to the present invention, since the body and the
cover are manufactured by a single process with one mold so as to
have a single body, respectively, the manufacturing cost of the
molds can be remarkably reduced. Further, since the shaft receiving
portion, which is formed of a same material so as to have a single
structure, is interposed in the shaft receiving recess of the body
by inserting only one shaft pin into the shaft receiving portion in
order to assemble the cover with the body, the manufacturing cost
of the cosmetic case can be remarkably reduced, thereby improving
the economical efficiency. Furthermore, since the cover is opened
and closed by one touch, the cosmetic case can be simply and easily
used and treated. Furthermore, since the cosmetic is efficiently
sealed in the cosmetic case, the cosmetic can be prevented from
being volatilized, thereby maintaining the original function of the
cosmetic so that the cosmetic can be used in a fresh state.
[0020] Although a preferred embodiment of the present invention has
been described for illustrative purposes, those skilled in the art
will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and
spirit of the invention as disclosed in the accompanying
claims.
