Description
CLOSURE OF VESSEL
Technical Field
[1] The present invention relates to a closure of a vessel for opening and
closing a vessel
inlet, and more particularly, to a closure of a vessel capable of enhancing a
user's
convenience by separating a sealing member sealed at a vessel inlet from a
vessel
together with the closure when the closure is opened.
Background Art
[2] FIG. 1 is a sectional view showing a closure of a vessel in accordance
with the con-
ventional art.
[3] Generally, a sealing member 152 for protecting contents stored in a vessel
150 is
attached to a beverage vessel, a drug vessel, etc. The sealing member 152 is
attached
onto a vessel inlet 160 in an adhesion manner, etc. In order to prevent the
sealing
member 152 from being damaged due to an external impact or collision with
objects,
the sealing member 152 is covered with a closure of a vessel 154.
[4] The closure of a vessel 154 is provided with a female screw portion 162 on
an inner
circumferential surface thereof, and a male screw portion 164 is formed at the
vessel
inlet 160. Under this configuration, once the closure of a vessel 154 is
opened, the
closure of a vessel 154 is detached from or mounted to the vessel inlet 160.
[5] As a user grips and rotates the closure of a vessel 154, the closure of a
vessel 154 is
detached from the vessel inlet 160. Then, the sealing member 152 is removed
from the
vessel inlet 160, and contents inside the vessel are discharged out through
the vessel
inlet 160.
[6] However, the conventional closure of a vessel has the problem that after
the closure
of a vessel is separated from the vessel, the sealing member attached to the
vessel inlet
has to be removed by a user's hand, or additional tools such as a knife.
Accordingly, a
user's inconvenience may be caused.
[7] Especially, when the sealing member is removed by a user's hand, the
sealing
member is not easily separated from the edge of the vessel inlet due to a
strong
adhesion force therebetween. Accordingly, the user has to remove the sealing
member
again, which may cause sanitary problems due to contact between the user's
hand and
the vessel inlet.
Disclosure of Invention
Technical Problem
[8] Therefore, it is an object of the present invention to provide a closure
of a vessel
capable of enhancing a user's convenience by additionally removing no sealing

2
member, in which when the closure of a vessel is opened, a sealing member is
separated from a vessel inlet thus to be stored in the closure of a vessel.
[9] It is another object of the present invention to provide a closure of a
vessel capable of
preventing environmental contamination by storing a sealing member removed
from a
vessel inlet when opening the closure, in the closure of a vessel not outside.
[10] It is still another object of the present invention to provide a closure
of a vessel
capable of solving sanitary problems due to contact between a user's hand and
a vessel
inlet when removing a sealing member, by automatically removing the sealing
member
by a sealing member removing unit.
Technical Solution
[11] To achieve these and other advantages and in accordance with the purpose
of the
present disclosure, as embodied and broadly described herein, there is
provided a
closure of a vessel, comprising: a body mounted to a vessel inlet through
which
contents inside a vessel are discharged out, and having a space therein; a
sealing
member mounted in the body, and sealed at the vessel inlet; and a sealing
member
separating unit formed on an inner circumferential surface of the body, for
separating
the sealing member from the vessel inlet when the body is opened, and storing
the
separated sealing member in the body.
[12] A concaved groove at an outer circumferential surface of the vessel inlet
may be
formed at an upper end of the vessel inlet. The sealing member may be adhered
to an
upper surface of the vessel inlet, and have an edge extending to outside from
the upper
end of the vessel inlet.
[13] The sealing member may consist of an elastic supporting layer formed of
paper or
synthetic resin, etc. with its own elastic force, and adhered to the vessel
inlet by being
elastically transformed when closing the closure of a vessel; a metallic layer
attached
to a lower surface of the elastic supporting layer, and formed of aluminum;
and an
adhesive layer deposited onto a lower surface of the metallic layer, and
adhering the
sealing member to the vessel inlet.
[14] The sealing member separating unit may be inwardly protruding from an
inner cir-
cumferential surface of the body, inserted into a groove of the vessel inlet,
and
disposed on a lower surface of an edge of the sealing member, for lifting and
separating the sealing member from the vessel inlet by being upwardly moved
when
the body is separated from the vessel inlet.
[15] The sealing member separating unit may consist of a supporting protrusion
formed in
the body in a circumferential direction, disposed on a lower surface of the
sealing
member, inserted into a groove of the vessel inlet, and supported by an edge
of the
sealing member; and a rotation protrusion disposed above the supporting
protrusion

with an interval therebetween, and locked by locking protrusions formed at the
edge of
the sealing member in a circumferential direction with the same interval, for
rotating
the sealing member so as to separate the sealing member from the vessel inlet
when the
body is rotated.
[16] According to another aspect of the present invention, there is provided a
closure of a
vessel, comprising: a body mounted to a vessel inlet through which contents
inside a
vessel are discharged out, and having a space therein; a sealing member
mounted in the
body, and sealed at the vessel inlet; a sealing member separating unit formed
on an
inner circumferential surface of the body, for separating the sealing member
from the
vessel inlet when the body is opened, and storing the separated sealing member
in the
body; and a sealing member locking unit formed at the body, and locked at an
inner
surface of the sealing member by penetrating the sealing member when being
pressed.
[17] The sealing member locking unit may consist of a pressing plate disposed
in the body
so as to be movable in upper and lower directions, and downwardly moving when
pressed by a user; a locking portion disposed on a lower surface of the
pressing plate,
and locked at a lower surface of the sealing member by penetrating the sealing
member
when the pressing plate is pressed; and a connection portion connected between
an
outer circumferential surface of the pressing plate and an inner
circumferential surface
of the body, for guiding the pressing plate to be moved in upper and lower
directions,
and supporting the pressing plate that has moved to another position by its
own elastic
force.
[18] One or more protrusions may be protruding from a coupling part between
the sealing
member and the vessel inlet at one of the sealing member and the vessel inlet,
or at
both of them.
[19] The body may be provided with one or more protrusions or groove portions
at a
contact part to the sealing member, and the protrusions or the groove portions
may be
radially formed.
Advantageous Effects
[20] The closure of a vessel of the present invention enhances a user's
convenience
because the sealing member is automatically removed from the vessel inlet when
opening the closure, after pressing the pressing plate of the sealing member
removing
unit installed in the closure.
[21] The closure of a vessel of the present invention can prevent
environmental con-
tamination by storing the sealing member removed from the vessel inlet when
opening
the closure, in the closure of a vessel not outside.
[22] The closure of a vessel of the present invention can solve sanitary
problems due to
contact between a user's hand and the vessel inlet when removing the sealing
member,

Mode for the Invention
[38] Hereinafter, a closure of a vessel according to the present invention
will be explained
in more detail.
[39] FIG. 2 is a sectional view showing a state that a closure of a vessel is
mounted to a
vessel according to a first embodiment of the present invention.
[40] The closure of a vessel according to a first embodiment of the present
invention
CA 02695290 2010-02-01
WO 2009/017371 PCT/KR2008/004456
comprises: a body 16 mounted to a vessel inlet 12 through which contents
inside a
vessel 10 are discharged out, and having a space therein; a sealing member 18
mounted
in the body 16, and sealed at the vessel inlet 12; and a sealing member
separating unit
formed on an inner circumferential surface of the body 16, for separating the
sealing
member 18 from the vessel inlet 12 when the body 16 is opened, and storing the
separated sealing member 18 in the body 16.
[41] The vessel 10 may be implemented as a beverage vessel, a drug vessel, or
an oil
vessel for storing liquid or solid contents. The sealing member 18 for
protecting
contents stored in the vessel 10 by sealing the vessel inlet 12 is attached to
the vessel
inlet 12.
[42] A concaved groove 20 at an outer circumferential surface of the vessel
inlet 12 the
may be formed at an upper end of the vessel inlet 12. The sealing member 18
may be
disposed so that its edge can cover the groove 20 of the vessel inlet 12. That
is, the
edge of the sealing member 18 is disposed to be extending outwardly from the
end of
the vessel inlet 12, and is not adhered to the vessel inlet 12 by the groove
20 formed at
the vessel inlet 12.
[43] As shown in FIG. 3, the sealing member 18 consists of an elastic
supporting layer 24
formed of paper or synthetic resin, etc. with its own elastic force, and
adhered to the
vessel inlet 12 by being elastically transformed when closing the closure of a
vessel; a
metallic layer 26 attached to a lower surface of the elastic supporting layer
24, and
formed of a metallic material, especially, aluminum; and an adhesive layer 28
deposited onto a lower surface of the metallic layer 26, and adhering the
sealing
member 18 to the vessel inlet 12.
[44] Under a state that the body 16 is mounted to the vessel inlet 12, once a
magnetic field
of a certain intensity is applied to the sealing member 18 (induction heating
method),
the sealing member 18 is attached to the vessel inlet 12 with the metallic
layer 26 being
heated and the adhesive layer 28 being melted.
[45] A male screw portion 30 is formed on an outer circumferential surface of
the vessel
inlet 12, and a female screw portion 32 is formed on an inner circumferential
surface of
the body 16. Accordingly, once the body 16 is rotated, the closure of a vessel
is
mounted to the vessel inlet 12, or separated from the vessel inlet 12. A skirt
34
connected with the body 16 by a plurality of bridges that can be easily
fractured is
formed at a lower end of the body 16, thereby maintaining a mounted state of
the body
16 to the vessel inlet 12. Here, as shown in FIG. 2, the skirt 34 is mounted
to the vessel
inlet 12 with a locked state by a protrusion of the vessel inlet 12. Once the
body 16 is
rotated, the skirt 34 serves to separate the body 16 and the vessel inlet 12
from each
other by being torn away. A plurality of concaved protrusions 36 to facilitate
rotation
of the body 16 by a user's hand are formed on an outer circumferential surface
of the
CA 02695290 2010-02-01
WO 2009/017371 PCT/KR2008/004456
6
body 16 in a circumferential direction.
[46] The body 16 may be coupled to the vessel inlet 12 by a snap method to
open the
body 16 in a pressing manner, as well as by a screw coupling manner. A
protrusion
(not shown) protruding towards an outer side may be formed at the end of the
vessel
inlet 12, and may be coupled to the body 16. Under a state that the body 16 is
coupled
to the vessel inlet 12 by a snap method, when the body 16 is separated from
the vessel
inlet 12, the sealing member 18 is separated from the vessel inlet 12 with a
mounted
state in the body 16.
[47] Under a state that the body 16 is coupled to the vessel inlet 12 by a
snap method, the
sealing member 18 can be separated from the vessel inlet 12 by rotating the
body 16
with respect to the vessel inlet 12.
[48] The sealing member separating unit is implemented as a ring-shaped
supporting
protrusion 22 protruding from an inner circumferential surface of the body 16
towards
inside of the body 16, and inserted into the groove 20 of the vessel inlet 12.
The groove
20 of the vessel inlet 12 may not be necessarily formed with consideration of
a plastic
material, and may be formed in a gradually concaved or convexed curved line.
[49] The supporting protrusion 22 is inserted into the groove 20 of the vessel
inlet 12, and
is disposed on a lower surface of the edge of the sealing member 18.
Preferably, the
sealing member 18 is formed to have a certain strength so as to be locked by
the
supporting protrusion 22 thereby to be separated from the vessel inlet 12, as
the body
16 is rotated to be lifted up.
[50] The supporting protrusion 22 is lifted up when the body 16 is lifted up,
and pushes
the sealing member 18 upwardly, thereby separating the sealing member 18 from
the
vessel inlet 12.
[51] In a processes for mounting the closure of a vessel to the vessel inlet
12, firstly, the
sealing member 18 composed of a plurality of stacked layers is inserted into
the body
16. Once the sealing member 18 is pushed into the body 16, the sealing member
18 is
bent by its own elastic force. Then, the sealing member 18 passes through the
supporting protrusion 22 thus to be disposed on an upper inner surface of the
body 16.
The sealing member 18 is locked by the supporting protrusion 22 thus to be
prevented
from being discharged out.
[52] Once the closure of a vessel having the sealing member 18 inserted
thereinto is
mounted to the vessel inlet 12, the adhesive layer 28 deposited onto a lower
end of the
sealing member 18 is adhered to an upper end of the vessel inlet 12. Under
this state, a
magnetic field having a certain intensity is applied to the closure of a
vessel (induction
heating method). As a result, heat is generated from the metallic layer 26,
and thereby
the adhesive layer 28 is melted to be attached to an upper surface of the
vessel inlet 12,
thereby protecting contents stored in the vessel 10.

[53] Here, the supporting protrusion 22 of the body 16 is in an inserted state
into the
groove 20 of the vessel inlet 12, and the edge of the sealing member 18 is
disposed
above the supporting protrusion 22.
[54] Hereinafter, processes for detaching the closure of a vessel mounted to
the vessel
inlet from the vessel inlet will be explained.
[55] FIG. 4 is a view showing an operational state of a closure of a vessel
according to a
second embodiment of the present invention.
[56] Once the body 16 is rotated in an open direction, the skirt 34 is torn
away to inform
that the body 16 is separated from the vessel inlet 12. Then, the body 16 is
lifted up.
[57] Here, the supporting protrusion 22 formed on an inner surface of the body
16 applies
force to the edge of the sealing member 18, with being lifted up together with
the body
16. As a result, the adhesive layer 28 of the sealing member 18 is separated
from the
vessel inlet 12, and thus the sealing member 18 is separated from the vessel
inlet 12.
The sealing member 18 is locked by the supporting protrusion 22, and maintains
a
stored state inside the body 16.
[58] Once the body 16 is rotated in an open direction, the sealing member 18
is separated
from the vessel inlet 12 thus to be stored in the body 16. This allows a user
not to ad-
ditionally tear away the sealing member 18, thereby enhancing a user's
convenience.
[59] On the contrary, when the body 16 is rotated in a closed direction with
respect to the
vessel inlet 12, the sealing member 18 is adhered to the vessel inlet 12.
Accordingly,
contents stored in the vessel 10 can be protected.
[60] FIG. 5 is a sectional view showing a closure of a vessel according to a
second
embodiment of the present invention, and FIGS. 6 and 7 are sectional views
taken
along line A-A' in FIG. 5.
[61] The closure of a vessel according to the second embodiment is the same as
that
according to the first embodiment, except for the sealing member separating
unit and
the sealing member.
[62] That is, the sealing member separating unit according to the second
embodiment
consists of a supporting protrusion 42 formed in the body 16 in a
circumferential
direction, disposed on a lower surface of the sealing member 40, inserted into
the
groove 12 of the vessel inlet 12, and supported by an edge of the sealing
member 40;
and a rotation protrusion 44 disposed above the supporting protrusion 42 with
an
interval therebetween, and locked by locking protrusions 46 formed at the edge
of the
sealing member 40 in a circumferential direction with the same interval, for
rotating
the sealing member 40 so as to separate the sealing member 40 from the vessel
inlet 12
when the body 16 is rotated.
[63] As shown in FIGS. 6 and 7, the sealing member 40 is provided with the
locking
protrusions 46 at an edge thereof arranged in a circumferential direction with
the same
CA 02695290 2010-02-01
WO 2009/017371 PCT/KR2008/004456
8
interval therebetween. The locking protrusions 46 may be implemented in a
concave-
convex shape, or in a shape inclined in one direction, etc.
[64] Preferably, the sealing member 40 is formed to have a certain strength so
as to insert
the rotation protrusion 44 and thereby to be rotated.
[65] The operation of the closure of a vessel according to the second
embodiment will be
explained.
[66] Once the body 16 is mounted to the vessel inlet 12, the supporting
protrusion 42
formed on an inner circumferential surface of the body 16 is inserted into the
groove
20 of the vessel inlet 12, and is disposed on a lower surface of an edge of
the sealing
member 40. And, the rotation protrusion 44 is in a locked state by the locking
protrusion 46 formed on an outer circumferential surface of the sealing
member.
[67] Under this state, once the body 16 is rotated, the rotation protrusion 44
is rotated with
a locked state by the locking protrusion 46 of the sealing member 40, thereby
pushing
the locking protrusion 46 of the sealing member 40. As a result, the adhesive
layer 28
of the sealing member 40 is torn away from the vessel inlet 12 due to the
pushing force
by the rotation protrusion 44.When the body 16 is further rotated, the
supporting
protrusion 42 is lifted up thereby to lift up the sealing member 40. As a
result, the
sealing member 40 is separated from the vessel inlet 12 with a locked state by
the
supporting protrusion 42, and maintains an accommodated state in the body 16.
[68] According to the closure of a vessel of the second embodiment, as the
rotation
protrusion 44 rotates the sealing member 44, the adhesive layer 28 of the
sealing
member 40 is torn away from the vessel inlet 12. And, the supporting
protrusion 42
separates the sealing member 40 from the vessel inlet 12 by lifting up the
sealing
member 40, and then stores the separated sealing member 40 in the body 16. Ac-
cordingly, the sealing member 40 can be more stably separated from the vessel
inlet
12.
[69] FIG. 8 is a sectional view showing a closure of a vessel according to a
third
embodiment of the present invention.
[70] The closure of a vessel according to the third embodiment is the same as
each closure
of a vessel according to the first and second embodiments, except for a
sealing member
locking unit 70 for detaching the sealing member 60 from the vessel inlet 12.
[71] The sealing member locking unit 70 consists of a pressing plate 72
disposed in the
body 16 so as to be movable in upper and lower directions, and downwardly
moving
when pressed by a user; a locking portion 74 disposed on a lower surface of
the
pressing plate 72, and locked at a lower surface of the sealing member 60 by
penetrating the sealing member 60 when the pressing plate 72 is pressed; and a
connection portion 76 connected between an outer circumferential surface of
the
pressing plate 72 and an inner circumferential surface of the body 16, for
guiding the
CA 02695290 2010-02-01
WO 2009/017371 PCT/KR2008/004456
9
pressing plate 72 to be moved in upper and lower directions, and supporting
the
pressing plate 72 that has moved to another position by its own elastic force.
[72] The pressing plate 72 is formed in a disc shape having a diameter smaller
than an
inner diameter of the body 16.
[73] As shown in FIG. 9, the locking portion 74 consists of a supporting rod
80
downwardly extending from a central part of a lower surface of the pressing
plate 72,
and penetrating the sealing member 60 when the pressing plate 72 is pressed;
and one
or more locking protrusions 82 formed on an outer circumferential surface of
the end
of the supporting rod 80, and locking the sealing member 60 so that the
sealing
member 60 can be stored in the body 16.
[74] Here, the supporting rod 80 is formed in a cylindrical bar
perpendicularly extending
from a central part of the pressing plate 72 in a lower direction, and is
provided with a
punch portion 84 at the end thereof. The punch portion 84 has a sharp shape so
as to
penetrate the sealing member 60.
[75] The locking protrusion 82 is formed to have an elastic transformation
force so as to
be upwardly bent. At the time of penetrating the sealing member 60, the
locking
protrusion 82 is upwardly bent thus to pass through a hole penetrated by the
punch
portion 84, and to be positioned at an inner side of the sealing member 60.
Once the
locking protrusion 82 is positioned at an inner side of the sealing member 60,
it is
extending to the original state thus to be locked at an inner side of the
sealing member
60.
[76] The locking protrusion 82 is formed so as to be perpendicularly extending
from an
outer circumferential surface of the supporting rod 80 by a certain length,
and is
formed on the outer circumferential surface of the supporting rod 80 in one or
more in
number. Preferably, one pair of locking protrusions 82 are formed on the outer
circum-
ferential surface of the supporting rod 80 with an interval of 180 .
[77] As aforementioned, the sealing member 60 is composed of the elastic
supporting
layer 24, the metallic layer 26, and the adhesive layer 28. A through hole 78
for
passing the locking portion 74 so that the sealing member 60 can be easily
penetrated
is provided at the elastic supporting layer 24.
[78] More concretely, when the pressing plate 72 is pressed, the locking
portion 74
penetrates the metallic layer 26 via the through hole 78 of the elastic
supporting layer
24.
[79] The connection portion 76 is formed between an outer circumferential
surface of the
pressing plate 72 and an inner circumferential surface of the body 16 as a
thin film
having a dome shape. The connection portion 76 is elastically transformed when
the
pressing plate 72 is pressed by a force more than a certain degree, thereby
guiding the
pressing plate 72 to be moved in a lower direction.
CA 02695290 2010-02-01
WO 2009/017371 PCT/KR2008/004456
[80] The connection portion 76 elastically maintains the current position of
the pressing
plate 72. More concretely, when the pressing plate 72 is upwardly protruding
(not
pressed state), the connection portion 76 maintains a convexed dome shape
thereby to
maintain the current position of the pressing plate 72. On the contrary, when
the
pressing plate 72 is pressed by a force more than a certain degree, the
connection
portion 76 is elastically transformed into a concaved shape thereby to
maintain a
pressed position of the pressing plate 72.
[81] As another embodiment, the connection portion 76 is implemented as an 'S'-
shaped
guide rib between the pressing plate 72 and an inner surface of the body 16.
Once the
pressing plate 72 is downwardly moved, the connection portion 76 is extending
to
guide a downward motion of the pressing plate 72, and to maintain a connected
state of
the pressing plate 72 to the body 16.
[82] The operation of the closure of a vessel according to the third
embodiment of the
present invention will be explained.
[83] FIGS. 10 and 11 are views showing an operational state of a closure of a
vessel
according to a third embodiment of the present invention.
[84] Once the pressing plate 72 is downwardly pressed, the connection portion
76 is
elastically transformed, and thus the pressing plate 72 is downwardly moved.
Then, the
supporting rod 80 of the locking portion 74 penetrates a central part of the
sealing
member 60. Here, the locking portion 74 can more easily penetrate the sealing
member
60 due to the through hole 78 of the elastic supporting layer 24 of the
sealing member
60.
[85] When penetrating the sealing member 60, the locking protrusion 82 of the
locking
portion 74 is upwardly bent to penetrate a hole formed by the punch portion 84
of the
supporting rod 80. Once being positioned at an inner side of the sealing
member 60,
the locking protrusion 82 is elastically transformed into the original state
thereby to be
positioned at an inner side of the sealing member 60 in an extending state.
[86] Then, once the body 16 is rotated in an open direction, the supporting
protrusion 22
formed on an inner surface of the body 16 applies force to an edge of the
sealing
member 60 with being upwardly moved together with the body 16. As a result,
the
adhesive layer 28 of the sealing member 60 is detached from the vessel inlet
12, and at
the same time, the sealing member 60 is detached from the vessel inlet 12.
[87] Since the sealing member 60 is in a locked state by the supporting
portion, the
sealing member 60 is detached from the vessel inlet 12 together with the body
16, and
maintains a stored state in the body 16.

member according to the present invention, FIG. 14 is a bottom view showing
the
sealing member of the closure of a vessel according to the present invention,
FIG. 15 is
a top view showing the sealing member of the closure of a vessel according to
the
present invention, FIG. 16 is an enlarged sectional view showing still another
coupled
state between the vessel inlet and the sealing member according to the present
invention, and FIG. 17 is an enlarged sectional view showing yet still another
coupled
state between the vessel inlet and the sealing member according to the present
invention.
[89] Preferably, the sealing member 18 of each closure of a vessel according
to the first to
third embodiments of the present invention is configured to be coupled to the
vessel
inlet 12 for sealing to prevent contents stored in the vessel 10 from being
discharged
out, and to be easily detached from the vessel inlet 12 when the closure is
rotated.
[90] Accordingly, the sealing member 18 of the closure of a vessel according
to the
present invention may be coupled to the vessel inlet 12 in various manners.
Here, the
sealing member 18 can be easily detached from the vessel inlet 12 by
minimizing a
coupling area between the sealing member 18 and the vessel inlet 12.
[91] In order to minimize a coupling area between the sealing member 18 and
the vessel
inlet 12, as shown in FIGS. 12 and 13, the sealing member 18 may be provided
with
one or more ring-shaped protrusions 18a protruding from a coupling part
between the
sealing member 18 and the vessel inlet 12. As shown in FIG. 14, the protrusion
18a is
preferably formed to have a circular shape. In order to complement a sealing
state, the
protrusion 18a may be formed in plurality in number.
[92] In order to minimize a coupling area between the sealing member 18 and
the vessel
inlet 12, as shown in FIGS. 16 and 17, one or more protrusions 12a may be
formed at a
coupling part of the vessel inlet 12 with the sealing member 18, under a state
the
protrusion 18a has been formed or has not been formed.
[93] Preferably, the protrusion 12a is formed to have a circular shape. Or,
the protrusion
12a may be formed to face the protrusion 18a of the sealing member 18, or to
be al-
ternately arranged with the protrusion 18a as shown in FIG. 17.
[94] Since the closure of a vessel has to be configured to be detached from
the vessel inlet
12 with rotating the sealing member 18 and detaching the sealing member 18
from the
vessel inlet 12, as shown in FIGS. 12 and 15, one or more protrusions 16a or
groove
portions may be formed on a lower surface of the body 16 of the closure of a
vessel.
[95] The protrusions 16a or groove portions may be configured in various
patterns such as
a rectangular shape, a circular shape, an wedge shape, etc., and are
preferably formed
at positions corresponding to a coupling parts between the sealing member 18
and the
vessel inlet 12. Here, the sealing member 18 may be provided with groove
portions
18b or protrusions corresponding to the protrusions 16a or the groove portions
of the

12
body 16. The sealing member 18 is formed with the groove portions 18b or
protrusions
corresponding to the protrusions 16a or groove portions of the body 16 due to
its
material characteristics. Accordingly, the groove portions 18b or the
protrusions cor-
responding to the concaved portions 16a or the protrusions of the body 16 are
not
necessarily formed.
[96] It will also be apparent to those skilled in the art that various
modifications and
variations can be made in the present invention without departing from the
spirit or
scope of the invention. Thus, it is intended that the present invention cover
modi-
fications and variations of this invention provided they come within the scope
of the
appended claims and their equivalents.
