Claims
1. A vessel having transparent windows comprising: an interior
vessel made of transparent material by injection-molding so as to
have an inlet in an upper end thereof for introduction of contents
and a protrusion oriented in a longitudinal direction thereof on
one side thereof; and an exterior vessel injection-molded
integrally with the interior vessel so as to cover a peripheral
surface of the interior vessel except the protrusion so that a
front surface of the protrusion of the interior vessel is exposed
to outside, wherein an amount of the contents in the interior
vessel can be checked by a user through the protrusion of the
interior vessel exposed outside.
Description
TECHNICAL FIELD
[0001] The present invention relates to a vessel having transparent
windows, and more particularly, to a vessel having transparent
windows which is easy to manufacture, has a reduced manufacturing
cost, and is competitive due to its beautiful appearance.
BACKGROUND ART
[0002] Recently, vessels having transparent windows provided to
sides thereof have been used so that the contents contained therein
can be easily checked from outside. Such a vessel includes an
interior vessel provided with transparent windows and made of
transparent material, and an exterior vessel, into which the
interior vessel is inserted. The vessels are formed such that the
interior vessel is covered with the metal exterior vessel, which
has an oblong slot in one side thereof. However, in the vessels
formed in this manner, a step is formed between the interior vessel
and the exterior vessel when the slot is viewed from outside, which
negatively affects the appearance of the vessel.
[0003] Subsequently, the vessel was formed in a manner such that an
oblong protrusion is formed on the side of the interior vessel, a
slot corresponding to the protrusion is formed in the exterior
vessel for insertion of the protrusion, and the interior vessel is
inserted in the exterior vessel. The upper end of the slot of the
exterior vessel must be open in order to allow the protrusion of
the interior vessel to be inserted therein, and the open upper end
negatively affected the appearance of the vessel. In addition,
since the interior vessel and the exterior vessel are separately
molded, a gap was formed between the protrusion of the interior
vessel and the slot of the exterior vessel at the time of assembly.
Accordingly, the problem in which the appearance is affected by the
upper end or the gap still remains.
DISCLOSURE OF INVENTION
Technical Problem
[0004] The present invention aims to solve these problems, and an
object of the invention is to provide a vessel having transparent
windows which is easily manufactured since an exterior vessel is
molded integrally with a transparent vessel in a manner such that
the transparent windows are exposed to outside and thus a separate
assembly process is thereby obviated, which can be manufactured at
the reduced manufacturing cost because the exterior vessel is
injection-molded, and which has a beautiful appearance.
Technical Solution
[0005] In order to achieve the above-described object, the
invention pertains to a vessel including: an interior vessel which
is made of transparent material, has an inlet formed in an upper
end thereof for allowing contents to be introduced thereinto, and
is made by injection molding so as to have a protrusion on a side
thereof, which is oriented in a longitudinal direction thereof; and
an exterior vessel which covers the exterior surface of the
interior vessel in a manner such that the front surface of the
protrusion of the interior vessel is exposed to outside and which
is made through injection molding so as to be formed integrally
with the interior vessel, in which the amount of the contents in
the interior vessel can be checked by a user through the protrusion
of the interior vessel, which is exposed to outside.
Advantageous Effects
[0006] As described above, according to the invention, the exterior
vessel 2 is integrally formed with the interior vessel 1 through
injection molding in a manner such that the front surface of the
protrusion provided on the side of the interior vessel 1 is exposed
to the outside. Accordingly, an additional assembly process is not
needed so that the vessel can be easily manufactured. In addition,
the invention can provide a vessel having a protrusion which can be
manufactured at decreased cost as compared to the known vessels
which are metal molded. Since a step, which is otherwise formed
between the interior vessel and the exterior vessel made of metal
material, is not formed, and a gap, which is formed when the
interior vessel and the exterior vessel are separately molded and
assembled, is not formed therebetween, a more beautiful appearance
can be provided. Further, since the exterior vessel 3 is
manufactured so as to cover the upper end of the protrusion 2 as
well as the lower end of the protrusion 2, a more beautiful
appearance can be provided compared to the known vessels which are
manufactured by assembly of the interior vessel and the exterior
vessel.

BEST MODE FOR CARRYING OUT THE INVENTION
[0012] Hereinafter, a preferred embodiment of the invention will be
described with reference to the accompanying drawings.
[0013] FIG. 2 is a perspective view illustrating a vessel having
transparent windows according to one embodiment of the invention,
and FIG. 3 is a sectional view of the embodiment.
[0014] As shown in the figures, the vessel having the transparent
windows according to the invention is technically characterized in
that an interior vessel 1, which has an inlet formed in the upper
end thereof for introduction of contents and a protrusion 2
protruding from one side thereof and oriented in a longitudinal
direction, is formed integrally with an exterior vessel 3, which
has an outside diameter corresponding to the diameter of an
imaginary circle passing the outermost surface of the protrusion 2
so that the outermost surface of the protrusion 2 is exposed
outside.
[0015] The interior vessel 1 is made of transparent synthetic resin
or the like by injection molding, injection blow molding or the
like, and it has an oblong tube shape. The interior vessel 1 has
the oblong tube shape extending in one direction and having the
open upper end serving as an inlet used for introduction and
discharge of the contents.
[0016] The interior vessel 1 is further provided with the elongate
protrusion 2 which has a pre-determined width, protrudes from the
side thereof and is oriented in the longitudinal direction thereof.
At this time, the interior vessel 1 is filled with the contents,
and the amount of the contents in the interior vessel 1 can be
checked through the protrusion 2.
[0017] The exterior vessel 3 is made of synthetic resin by
injection molding so as to be formed integrally with the interior
vessel 1 and to cover the interior vessel 1. The exterior vessel 3
has an oblong tube shape and surrounds the interior vessel 1. In
one side of this exterior vessel 3 there is an oblong slot 4
corresponding to the protrusion 2. Accordingly, the protrusion 2 of
the interior vessel 1 is exposed to outside, and thus a user can
check the amount of the contents remaining in the interior vessel 1
through the protrusion 2, and the protrusion 2 forms a transparent
window when viewed from the outside of the vessel. Reference
numeral 5, which has not been described, denotes a cap for covering
the upper end of the vessel.
[0018] The exterior vessel 3 can be marked with a scale (not shown)
through a printing or carving process on the exterior surface on
one side of the portion through which the protrusion 2 of the
interior vessel 1 is exposed, so that the user can easily check the
amount of the contents.
[0019] Processes of manufacturing the vessel having the transparent
windows formed in this manner will be described below.
[0020] First, the interior vessel 1 is manufactured through
injection molding or the like, and then injection molding is also
performed using a mold surrounding the interior vessel 1 so that
the peripheral surface of the interior vessel 1 is covered with the
exterior vessel 3. In this way, a finished product of the vessel is
manufactured. At this time, the injection molding is performed in a
manner such that the protrusion 2 is exposed to outside. In
addition, the injection molding must be performed in a manner such
that the total thickness of the side walls of the interior vessel 1
and the exterior vessel 3 is 3 mm or less. That is, the thickness
of the interior vessel 1 including the protrusion 2 is about 3 mm.
On the other hand, according to the conventional method, the
protrusion of vessels is about 6 mm thick because the exterior
vessel and the interior vessel are separately manufactured and then
assembled into a vessel. This generally leads to thermal
deformation of the vessel. Accordingly, the protrusion of the
conventional vessel has been provided with a slot on the inside
surface thereof for the purpose of suppressing thermal deformation
of the vessel by reducing the total thickness of the protrusion. On
the other hand, there is almost no likelihood that the vessel
according to the invention is thermally deformed even though it
does not have a slot on the inside surface of the protrusion.
Moreover, since the exterior vessel 3 has the elongated slot 4
corresponding to the protrusion 2, contributing to the tight
contact between the entire side of the protrusion 2 and the
exterior vessel 3, the gap, which is formed when the conventional
interior and exterior vessels are separately molded and assembled,
or the step, which is formed when the interior vessel is covered
with the metal exterior vessel, is not formed, whereby a beautiful
appearance can be provided.
[0021] The invention described above is not limited to the
above-described embodiment and the accompanying drawings, but it
will be understood by those skilled in the art that various
substitutions, modifications and changes can be made without
departing from the technical scope and spirit of the invention.
