CLOSURE WITH PUSH TYPE OPENER
TECHNICAL FIELD
The present invention relates to a closure with a push type opener
and, more particularly, to one piece or two or more pieces of closures
capable of opening a sealing member which blocks an inlet of a container
or an inner side of a closure by pressing it, and capable of automatically
inserting a slit sealing member inside the closure for storage.
BACKGROUND ART
Figure 1 is a sectional view showing a closure of a container of a
beverage container (bottle) having an opening structure in accordance with
a conventional art.
The closure of a beverage container includes a closure body 5
detachably coupled at an inlet of a container 1 sealed by a sealing member
2; an ascending/descending member 6 installed to be moved linearly up
and down at an upper outer side of the closure body 5; and an auxiliary
closure 7 capped at an upper portion of the closure body 5.
When a user wants to drink a beverage in a closure-capped
2 o container, the user may separate the closure body 5 from the beverage
container 1 and remove the sealing member 2 blocking the inlet of the
container 1. And then, the user may couple the closure body 5 to the inlet
of the beverage container 1, open the auxiliary closure 7 and grasp the
ascending/descending member 5 by hand and pull it upwardly. Then, an
1
CA 02516057 2005-08-12
WO 2004/085278 PCT/KR2004/000303
upper side surface 6' of the ascending/descending member 6 is isolated
from a head part 5' of the closure body to open the closure of the beverage
container 1, so that the user can drink the beverage by inclining the
beverage container 1.
If the user does not want to drink the beverage any further, he/she
can press the ascending/descending member 6 by hand to return it to its
original position, thereby closing the inlet of the beverage container 1.
However, the conventional closure of the beverage container having
such an opening structure has the following problems.
That is, in order to open the container, the closure body 5 is
separated from the container 1, the sealing member 2 is removed, and
then, the closure body 5 is coupled again to the beverage container 1,
causing inconvenience to open the closure.
Especially, since the sealing member 2 is firmly attached for sealing
at the inlet of the container 1, it is not easy for the user to open it, and
thus,
in most cases, the user must open it by hand, causing a problem that the
inlet of the container 1 is contaminated in the process of removing the
sealing member 2, which is not hygienic.
In addition, the conventional closure makes it difficult to keep a
different content from a current content put in the container 1, so a
container is additionally required or the structure of the closure is to be
formed more complicate.
Moreover, when the user wants to drink a beverage contained in the
beverage container, he/she must open the closure by putting up the
2
CA 02516057 2005-08-12
WO 2004/085278 PCT/KR2004/000303
ascendingldescending member 6 by hand, and after finishing drinking the
beverage, he/she must push the ascending/descending member to its
original position by hand, contaminating the portion where the beverage is
discharged, which is thus insanitary.
TECHNICAL GIST OF THE PRESENT INVENTION
Therefore, it is one object of the present invention to provide a
closure with a push type opener capable of opening a container
hygienically, removing a sealing member simply and keeping a slit sealing
member inside a closure for storage by constructing such that the sealing
member for sealing an inlet of the container is opened by pressing without
separating the closure from a container, and mounting a spoon for a user
to have a content in the closure to thereby avoid users' inconvenience of
preparing a spoon personally.
Another object of the present invention is to provide a closure with a
push type opener capable of improving users' convenience with a
construction that a mixed beverage or a food stuff can be kept in one
container and closure without a necessity of keeping them in individual
containers, and contents contained in each container and closure can be
2 o mixed by opening a sealing member by pressing, to thereby simplify
keeping and mixing individual contents.
Referring back to a problem of the conventional art, when the
sealing member mounted at the inlet of the container is to be removed, the
closure is first released from the container, the sealing member is torn off
3

WO 2004/085278 PCT/KR2004/000303
directly by hand or by using a tool (knife or a gimlet), and then, the content
in the container can be used. In such a case; it is quite inconvenient for a
user to use the closure, the sealing member is quite roughly torn off, and it
is not easy to handle and keep the removed sealing member in storage.
In order to accomplish the above objects, there is provided a closure
having an inlet in the container processed by a sealing member or having a
sealing member mounted in the closure, including a device for cutting the
sealing member and keeping slit sealing member in the closure for storage,
whereby in a state that the closure is coupled at the inlet of the container,
a
1o spoon 13 mounted at an upper portion of the closure is released without
isolating the closure and the container, and a pressing plate 32 of an upper
end portion of a hemispherical (dome) region 30 of an upper portion of the
closure by the thumb is vertically pressed to make the sealing member
sealed at the inlet of the container be penetrated by several cutting blades
42 installed at a lower portion of a cutting region 40 of the closure (Refer
to
a principle presented in a 'Waveform Annular Body and other Cap(B)
described with reference to Figure 1 of Japanese Application No. Sho
57-126367 entitled 'Cap' filed on February 3, 1981 by the applicant of
DAINIPPON INK AND CHEMICALS, INC., a former patent application),
2 0 and then, when the closure is rotated in an opening direction, the sealing
member is completely cut by cutting blades 44 of a cutting support 41 and
smoothly inserted into a sealing member keeping recess 43 in the closure.

Preferred embodiments of the present invention will now be
2 o described with reference to the accompanying drawings.
The structure of a closure in accordance with the present invention
will be described as follows.
The closure is divided into an outer wall region 10, a hemispherical
(dome) region 30 and a cutting region 40.
6
CA 02516057 2005-08-12
WO 2004/085278 PCT/KR2004/000303
The outer wall region 10 is coupled at its lower portion to an inlet of
a container 1, and its upper portion is more protruded than the inlet of the
container. A spoon mounting jaw 14 and a wrapper installation jaw 16 are
installed at an outer wall 11 of the outer wall region 10. A knurl 12 is
installed at an outer surface of the outer wall region. At a lower side of the
outer wall region 10 coupled to the inlet of the container 1, there are
formed a sealing portion 17, a connected potion 18, a perforated portion 19
or an under cut 20, and the knurl 12A.
The dome region 30 is surrounded by an upper portion-opened
cylindrical outer wall 11, and includes a pressing plate 32 installed at an
upper end of a hemisphere (dome) 31, a thin connection film 33 connecting
the outer wall region and the hemispherical (dome) region. The thin
connection film has at least one crease 34.
The cutting region 40 is installed at a lower inner portion of the
dome region. The cutting region 40 has a cylindrical shape with a lower
portion opened, and is installed in a vertical direction. The cutting region
40
includes a cutting support 41 required for penetrating and cutting a sealing
member, a cutting blade 42, a cutting support blade 44 for slitting the
sealing member, and a sealing member keeping recess 43 for keeping the
2 o slit sealing member.
A first embodiment of the present invention will now be described
with reference to Figures 3 and 4.
A closure includes a wrapper installation jaw 16 installed at the inner
surface or the outer surface of the outer wall (protecting wall) 11, a
7
CA 02516057 2005-08-12
WO 2004/085278 PCT/KR2004/000303
wrapper 15 mounted at the wrapper installation jaw 16, the spoon
mounting jaw 14 installed at the inner surface of the outer wall 11, a spoon
for scooping a content, a pressing plate 32 formed thicker than the
connection film 33 of the dome region 30, a crease 34 allowing the
connection film to be easily folded, a cutting blade 42 of the cutting region
40 penetrating the sealing member, a sealing member keeping recess 43
keeping the slit sealing member, and a cutting support blade 44 of the
cutting support 41 for completely slitting the penetrated sealing member.
The closure according to the first embodiment of the present
1o invention is applied to a container in which content 3 is put in a paste
state,
or content such as a thick solution or a powder product, which a user can
have with a spoon.
A second embodiment of the present invention will now be
described, in which the closure does not have such a spoon mounting jaw
and a spoon as in the first embodiment of Figures 3 and 4.
Its operational order is as follows.
1 ) The wrapper 15 mounted at the wrapper installation jaw 16
installed at an inner or outer surface of the outer wall (protection wall) 11,
namely, a portion of the outer wall region 10 of the closure is removed by
using fingers or other tools.
2) The pressing plate 32 of the dome region is softly pressed by the
thumb in a vertical direction downwardly.
3) The thin connection film 33 is folded by virtue of the pressing
force and the cutting region 40 also descends.
8
CA 02516057 2005-08-12
WO 2004/085278 PCT/KR2004/000303
4) The cutting blade 42 of the cutting region 40 installed at the lower
side of the dome region 30 mounted at the inlet of the container descends
to penetrate the sealing member 2, and at this time, the folded thin
connection film 33 remains folded, not being recovered to its original state.
5) The sealing member which has been penetrated by the cutting
blade 42 is inserted in the sealing member keeping recess 43 (Refer to
Figure 4).
6) In order to release the closure from the container, the closure is
rotated in an opening direction.
7) A portion of the sealing member 2 inserted in the sealing member
keeping recess 43, which has survived the cutting and thus remained intact,
if any, is cut by the sharp cutting support blade 44 installed perpendicular
in the opening direction to the side of the cutting support 41 and inserted
into the sealing member keeping recess 43 completely, and the slit sealing
member 2A is kept in the sealing member keeping recess 43 of the
closure.
The closure in accordance with the second embodiment of the
present invention is applied to a container which holds a watery solution
that users may have by applying their mouths to the container, or to a
container having a content can be poured into a different container for a
user to have, e.g., milk, watery yogurt, cafe latte, or the like.
A third embodiment of the present invention will now be described.
In such a structure of the closure as in first embodiment, an open
bar 46 for penetrating the sealing member to open it is installed at a lower
9
CA 02516057 2005-08-12
WO 2004/085278 PCT/KR2004/000303
portion of the pressing plate of the hemispherical region, and an upper
space for storing content inside the hemispherical region is formed.
A fourth embodiment of the present invention will now be described.
Figures 11 and 12 illustrate installation of the cutting region 40 at an
inner wall surface of the outer wall region, without having the hemispherical
region 30. A closure in accordance with the fourth embodiment of the
present invention operates as follows.
1 ) A closure 4 coupled spaced with a certain interval 50 from the
inlet of the container 1 with the sealing member 2 mounted therein is
rotated (in case of a screw) in a closing direction and descends vertically
by a pressing force (in case of an undercut) to be closed completely.
2) The perforated portion 19 of the sealing portion 17 is torn off by
virtue of the rotational force or the vertical descending force and the
closure is tightly attached to the inlet of the container.
3) The sealing member 2 is penetrated by the cutting blade 42
installed at the inner surface of the closure 4, cut by the cutting support
blade 44 and completely separated from the inlet of the container 1.
4) The completely slit sealing member 2A is released from the inlet
of the container and inserted into the sealing member keeping recess 43.
5) When the closure 4 is rotated in an opening direction, the
connected portion 18 is torn and the perforated portion 17 is caught by a
protrusion of the lower portion of a screw installed at an outer surface of
the inlet of the container to remain there while the sealing member 2A is
kept in the sealing member keeping recess 43. In this state, the closure 4
CA 02516057 2005-08-12
WO 2004/085278 PCT/KR2004/000303
is released from the inlet of the container.
The closure is applied to a container which holds a content 3 in a
paste state, or content such as a thick solution or a powder product which
a user can have with a spoon.
As stated above, when the closure coupled at the inlet of the
container 1 with the sealing member 2 mounted therein is opened, the
sealing member 2 is automatically penetrated, slit and inserted for storage
in the sealing member keeping recess 43 inside the closure.
In addition, the closure mounted at the inlet of the
sealing-processed container which automatically keeps the sealing
member 2A when it is opened .can be applicable to any containers so long
as they are sealing-processed regardless of a content, rather than being
limited to the beverage container, and a design (or pattern) of the closure
is to be interpreted to come within the coverage of the present invention.
INDUSTRIAL APPLICABILITY
As so far described, the closure with the push type opener in
accordance with the present invention has the following advantages.
That is, for example, first, since the sealing member capping the
2 o container can be opened by the pressing method, a user cannot be
bothered to separate the closure in order to remove the sealing member to
take the content of the container.
Second, because the user can easily open the inlet of the container
without applying hands to the inlet of the container in order to remove the
11
CA 02516057 2005-08-12
WO 2004/085278 PCT/KR2004/000303
sealing member to have a beverage or a content of the container, he/she
can take the content hygienically.
Third, with a content stored inside the closure, the sealing member
can be opened by the pressing method, and the content stored inside the
closure and a content stored in the container can be mixed. Accordingly,
the user can simply mix the different contents to have it.
Fourth, since the sealing member mounted at the inlet of the
container is removed and automatically stored inside the closure, the slit
sealing member does not remain as waste.
1o Finally, since a spoon or a straw can be kept in a space of an upper
portion of the closure, a user can easily use them for having a content of
the container, and in addition, by providing a closure cover, it accomplishes
effectiveness of advertising as well as preventing introduction of foreign
materials to thereby improve hygiene of the spoon or the straw.
