according to a person of a related field or conventional practice.
Therefore, the terms should be defined on the basis of the entire
content of this specification.
[0042] Technical terms used in the present specification are used
only in order to describe specific exemplary embodiments rather
than limiting the present invention. The terms of a singular form
may include plural forms unless referred to the contrary. It will
be further understood that the terms "comprise" and/or

features, integers, steps, operations, elements, and/or components,
but do not preclude the presence or addition of one or more other
features, regions, integers, steps, operations, elements,
components, and/or groups thereof.
[0043] In addition, hereinafter, when it is described that
thicknesses, widths, or lengths of certain components are the same,
it means that a thickness, width, or length of a first component is
within an error range of 10%, compared to a thickness, width, or
length of a second component in consideration of process
errors.
[0044] Hereinafter, a receptacle and auxiliary contents holding
device according to an embodiment of the present disclosure will be
described with reference to the accompanying drawings.
[0045] First, a receptacle 1 according to an embodiment of the
present disclosure will be described with reference to FIGS. 1 and
2.
[0046] The receptacle 1 of this embodiment may include a receptacle
stopper 10, a coupling portion 23 with a screw thread 25 located on
an outer side surface thereof, and a receptacle body 20 coupled to
the receptacle stopper 10 through the coupling portion 23.
[0047] The receptacle stopper 10 may be coupled to the receptacle
body 20 to prevent the contents held in the receptacle body 20 from
leaking to the outside.
[0048] As shown in FIG. 1, the receptacle stopper 10 may include a
cap portion 11 having an upper surface and a side surface, a screw
thread 131 and a protrusion 132 located on an inner side surface of
the cap portion 11, and a sealing portion 15 located in the cap
portion 11 to directly or indirectly cover the coupling portion
23.
[0049] The cap portion 11 has a circular planar shape and, as
described above, the cap portion 11 may have the upper surface and
the side surface and a lower part thereof may be opened.
[0050] The cap portion 11 may be coupled to the coupling portion 23
of the receptacle body 20 using a screw thread 131 formed on an
inner side surface.
[0051] Therefore, after the coupling portion 23 of the receptacle
body 20 is inserted into a space S11 surrounded by the upper
surface and the side surface through the open lower part of the cap
portion 11, the cap portion 11 may be coupled to or decoupled from
the coupling portion 23 of the receptacle body 20 according to
rotation in a corresponding direction.
[0052] The screw thread 131 may be one screw thread connected
seamlessly in a spiral shape along the inner side surface of the
cap portion 11 from bottom to top on the inner side surface of the
cap portion 11.
[0053] The screw thread 131 may be coupled with a screw groove 25
located on an outer side surface of the coupling portion 23 of the
receptacle body 20 to control the coupling and decoupling operation
of the cap portion 11.
[0054] Accordingly, a user may close or open the cap portion 11
with the coupling portion 23 of the receptacle body 20 by rotating
the cap portion 11 in a counterclockwise direction and a clockwise
direction, respectively.
[0055] The protrusion 132 located on the inner side surface of the
cap portion 11, such as the screw thread 131, serves to support a
position of the sealing portion 15.
[0056] The protrusion 132 may be located on the screw thread 131
and connected seamlessly in a spiral form along a corresponding
portion of the inner side surface of the cap portion 11 together
with the screw thread 131.
[0057] The protrusion 132 may be seamlessly connected to the screw
thread 131 which is substantially coupled to the coupling of the
coupling portion 23 and the cap portion 11. In this case, the
protrusion 132 may be integrally formed with the screw thread 131
and may or may not be involved in the coupling operation of the
coupling portion 23 and the cap portion 11.
[0058] In another example, the protrusion 132 may not be connected
to the screw thread 131 and disconnected. In this case, the
protrusion 132 is located on the inner side surface of the cap
portion 11 in a spiral shape by a predetermined length, and the
screw thread 131 may be located in a spiral shape with a
predetermined length apart from the protrusion 132 therebelow.
[0059] In this embodiment, as an example, a case where the coupling
portion 132 is seamlessly connected to the screw thread 131 is
illustrated and described.
[0060] The sealing portion 15 is adjacently spaced apart from an
inner upper surface of the cap portion 11 and closes an upper part
of the coupling portion 25 of the receptacle body 20 to prevent the
contents held in the receptacle body 20 from flowing to the outside
regardless of user intention.
[0061] Accordingly, the sealing portion 15 may have a circular
planar shape, and as shown in FIG. 1, the sealing portion 15 may
include a support layer 151 having a circular planar shape and an
airtight sheet 152 adhered to a lower part of the support layer 151
through an adhesive or heat and having a circular planar shape as
well.
[0062] The support layer 151 serves to support the shape of the
sealing portion 15, may be formed of a synthetic resin such as
polypropylene (PP), and may have a circular thin plate shape.
[0063] The airtight sheet 152 may include a substrate formed of a
material containing aluminum or a synthetic resin such as
polyethylene (PE).
[0064] The airtight sheet 152 may be adhered or fused to a lower
surface of the support layer 151 using the sheet-shaped substrate
and an adhesive or heat applied to an upper surface of the
substrate, so that the entire upper surface of the airtight sheet
152 may be safely adhered to the lower surface of the support layer
151.
[0065] In addition, at least a portion of a lower surface of the
substrate may be adhered to an upper end of the coupling portion 23
of the receptacle body 20 corresponding thereto through an adhesive
or a fusing operation.
[0066] In this case, the airtight sheet 152 may include a metal
material having conductivity and may have a melting point lower
than that of the support layer 151.
[0067] Accordingly, when the airtight sheet 152 and the upper end
of the coupling portion 23 are fused using an electromagnetic
induction heating method, heat may be generated from the airtight
sheet 152 due to the metal material contained in the airtight sheet
152, so that the airtight sheet 152 may be fused with the upper end
of the coupling portion 23.
[0068] Here, since the melting point of the airtight sheet 152 is
lower than that of the support layer 151, even when heat is applied
to or generated in the airtight sheet 152, the airtight sheet 152
and the coupling portion 23 may be stably fused before the support
layer 151 and the cap portion 110 in contact with each other are
fused.
[0069] In this embodiment, the airtight sheet 152 may be located on
the entire lower surface of the support layer 151 and exposed to
the outside, and a diameter of the airtight sheet 152 may be equal
to a diameter of the support layer 151.
[0070] As shown in FIG. 3, the support layer 151, specifically, the
sealing portion 15, coupled to the upper end of the coupling
portion 23 may be located between portions of the protrusion 132
most adjacent to an inner side (hereinafter, the inner side of the
upper surface is referred to as "inner upper surface") of the upper
surface of the cap portion 11.
[0071] Since the protrusion 132 is located along the inner side
surface of the cap portion 11 in a spiral shape seamlessly as
described above, the protrusion 132 protrudes inward from the inner
side surface of the cap portion 11 by a predetermined distance.
[0072] Due to the shape of the protrusion 132, the protrusion 132
may be located on the inner side surface of the cap portion 11 and
include two protruding portions, e.g., a first protruding portion
T131 and a second protruding portion T132, spaced apart from each
other by different distances from the upper end of the cap portion
11.
[0073] Accordingly, as shown in FIGS. 2 and 3, in the protrusion
132, a height of the protrusion portion (e.g., the first protrusion
part) T131 most adjacent to a first end P151 of the sealing portion
15 or the support layer 151 and a height of the protruding portion
(e.g., the second protruding portion) T132 most adjacent to a
second end P152 of the sealing portion or the support layer 151
located on the opposite side of the first end 151 and facing the
first end P151 may be different from each other.
[0074] In this embodiment, the height of the first protrusion part
T131 may be higher than the height of the second protrusion part
T132. Here, the first protrusion part T131 and the second
protrusion part T132 face each other from opposite sides.
[0075] Accordingly, the height of the first protrusion part (e.g.,
T131) of the protrusion 132 overlapping the first end P151 of the
sealing portion 15 or the support layer 151 may be higher than the
height of the second protrusion part (e.g., T132) overlapping the
second end P152.
[0076] Here, as described above, the sealing portion 15 is
positioned on the nearest protrusion portion and may overlap the
corresponding protrusion portion by a predetermined length, so that
the first end P151 and the second end P152 may overlap the first
protrusion part T131 and the second protrusion part T132 on the
corresponding protrusion portions T131 and 132, respectively.
[0077] A maximum diameter of the sealing portion 15 or the support
layer 151 may be equal to a diameter of the inner upper surface of
the cap portion 11, and a minimum diameter of the sealing portion
15 or the support layer 151 may be larger than a diagonal distance
R1 between the innermost side end of the first protrusion part T131
and the innermost side end of the second protrusion part T132.
[0078] Therefore, when the cap portion 11 moves upward, while
rotating along the outer side surface of the coupling portion 23
according to the operation of the screw thread 131 and the screw
groove 25, the ends P151 and P152 of the sealing portion 15 may be
caught by the adjacent protrusion portions T131 and T132 and move
upward together, thus releasing a sealed state.
[0079] In this way, the protrusion portions T131 and T132 located
on the inner side surface of the cap portion 11 and located at the
top adjacent to the inner upper surface may serve to release the
coupled state of the sealing portion 15 or the support layer
151.
[0080] This sealing portion 15 is not adhered anywhere inside the
cap portion 11.
[0081] Therefore, as shown in FIG. 2, when the sealing portion 15
is separated from the coupling portion 23 of the receptacle body 20
and positioned in the space S11 of the cap portion 11 due to the
opening operation of the cap portion 11, the sealing portion 15 may
be inclined toward the ground, i.e., downward, in the cap portion
11 due to the influence of gravity, and in this case, the first and
second protrusion parts T131 and T132 located at different heights
may serve as engaging projections of the sealing portion 15.
[0082] That is, as shown in FIG. 2, the first end P151 of the
sealing portion 15 or the support layer 151 may be caught by the
first protruding portion T131 so as to be limited in a range of
descending downward, and the second end P152 of the sealing portion
15 or the support layer 151 may be caught by the second protrusion
part T132 so as to be limited in a range of descending
downward.
[0083] As shown in FIG. 3, since the airtight sheet 152 of the
sealing portion 15 is directly adhered to the upper end of the
coupling portion 23 to completely seal the open coupling portion
23, the airtight sheet 152 may perform an airtight function of the
contents stored in the receptacle body 20.
[0084] In this case, adhesion between the support layer 151 and the
airtight sheet 152 may be greater than adhesion between the
airtight sheet 152 and the upper end of the coupling portion 23, so
that when the cap portion 11 is opened, the airtight sheet 152 may
be stably separated from the upper end of the coupling portion 23
together with the support layer 151.
[0085] The receptacle body 20, as described above, may accommodate
the contents and is coupled with the cap portion 11 to protect the
contents held therein.
[0086] This receptacle body 20 may include a body 21 having a space
S21 to hold the contents therein and an open upper part, the
coupling portion 23 located at an upper portion of the body 21 and
having an inlet H23 provided in the middle thereof and
communicating with the space S21 of the body 21, and the screw
groove 25 coupled to the screw thread 131 located on the outer side
surface of the coupling portion to control an opening and closing
operation of the cap portion 11.
[0087] Since the screw groove 25 is coupled with the screw thread
131 located on the inner side surface of the cap portion 11, the
screw groove 25 may also have a spiral form from the bottom to the
top on the outer side surface of the coupling portion 23 to
correspond to the screw thread 131.
[0088] Next, an operation in which the receptacle stopper 10 having
such a structure is coupled to the receptacle body 20 to assemble
the receptacle 1 that holds the contents and the receptacle stopper
10, that is, the cap portion 11, is opened will be described.
[0089] First, an assembler may perform an operation of sealing the
inlet H23 of the receptacle body 20 holding the contents using the
inlet H23 of the coupling portion 23 by the sealing portion 15.
[0090] To this end, the assembler may apply an adhesive to the
upper end of the coupling portion 23, position the airtight sheet
152, which is adhered to the support layer 15 and has an adhesive
applied to a lower surface thereof, at the upper end of the
coupling portion 23, and then apply pressure to completely close
the inlet H23.
[0091] In an alternative example, the assembler may apply an
adhesive to the upper end of the coupling portion 23, position the
sealing portion 15 to be in contact with the coupling portion 23
thereon, or apply pressure, or the assembler may position the
sealing portion 15 to be in contact with the coupling portion 23 on
the coupling portion and irradiate heat or ultrasonic waves to a
desired part to completely seal the inlet H23 with the sealing
portion 15 through heat sealing or ultrasonic welding. In this
case, it may not be necessary to apply an adhesive to a lower
surface of the airtight sheet 152, that is, a lower surface of the
substrate.
[0092] Through this operation, the inlet H23 of the receptacle body
20 holding the contents may be sealed by the sealing portion
15.
[0093] Thereafter, the assembler may couple the cap portion 11 with
the coupling portion 23 of the receptacle body 20 to couple the cap
portion 11 to the receptacle body 20 as shown in FIG. 4B.
Accordingly, the receptacle stopper 10 may be coupled to the
receptacle body 20.
[0094] In this way, airtightness of the contents held in the
receptacle body 20 may be maintained by the attaching operation of
the airtight sheet 152 and the upper end of the coupling portion 23
of the receptacle body 20, thus eliminating a possibility of
outflow of contents while the receptacle 1 holding the contents is
moved.
[0095] In this state, in order to open the cap portion 11 which
closes the receptacle body 20 to drink the contents of the
receptacle body 20, a user may rotate the cap portion 11 in a
direction (e.g., counterclockwise direction) opposite to a
direction in which the cap portion 11 is coupled to the receptacle
body 20, to decouple the cap portion 11 and the receptacle body 20
[FIG. 4C].
[0096] As the decoupling of the cap portion 11 is performed, the
cap portion 11 moves upward, while rotating along the screw groove
25 of the coupling portion 23 of the receptacle body 20.
[0097] The first protrusion part T131 located at the uppermost end
of the protrusion 132 located on the inner side surface of the cap
portion 11 moves, while pushing up a part (e.g., a first end P151)
of the adjacent sealing portion 15.
[0098] Due to the lifting operation of the cap portion 11, adhesion
of a part of the sealing portion 15 is weakened and separated from
the upper end of the coupling portion 23 and moved upward together
with the cap portion 11, and due to the decoupling operation of the
cap portion 11 and the sealing portion 15, the entire part of the
sealing portion 15 coupled to the upper end of the coupling portion
23 is resultantly decoupled and located inside the cap portion 11
[FIGS. 4C and 4D].
[0099] Here, the sealing portion 15 is not entirely separated from
the coupling portion 23 at once but separated, starting from a part
thereof, from the coupling portion 23, and as a result, the sealing
portion 15 may be separated from the coupling portion 23 with less
force.
[0100] In this way, the sealing portion 15 adhered to the upper end
of the coupling portion 23 may be removed from the coupling portion
23 of the receptacle body 20 only by the decoupling operation of
the cap portion 11, so that the user may take or drink the contents
of the receptacle body 20 simply and conveniently without
performing a separate operation of removing the sealing portion
15.
[0101] Next, a receptacle 1a according to another example of the
present disclosure will be described with reference to FIGS. 5 to
7D.
[0102] In the following embodiments, compared to the receptacle 1
shown in FIG. 1, components having the same structure as the
receptacle 1 are denoted by the same reference numerals and
detailed descriptions thereof will be omitted.
[0103] As shown in FIGS. 5 to 6B, the receptacle 1a of the present
embodiment may also include the receptacle stopper 10 and the
receptacle body 20 to which the receptacle stopper 10 is
coupled.
[0104] The receptacle stopper 10 has the same structure as the
receptacle stopper 10 described above with reference to FIGS. 1 to
3, and thus, the receptacle stopper 10 may include the cap portion
11, the screw thread 131 and the protrusion 132 located in a spiral
shape on the inner side surface of the cap portion 11, and the
sealing portion 15 freely located in the internal space of the cap
portion 11.
[0105] The sealing portion 15 may include the support layer 151 and
the airtight sheet 152 adhered to the support layer 151 as
described above.
[0106] As shown in FIG. 5, the airtight sheet 152 may be located at
an upper part of the coupling portion 23 to seal the inlet H23.
Also, in this case, the diameter of the support layer 151 and the
diameter of the airtight sheet 152 may be equal.
[0107] The receptacle body 20 may also include the body 21 having
the space S21 to hold the contents therein and the open upper part,
the coupling portion 23 located at an upper portion of the body 21
and having the inlet H23 communicating with the space S21 of the
body 21, and the screw groove 25 located on the outer side surface
of the coupling portion.
[0108] However, the receptacle 1a of this embodiment may further
include an auxiliary content holding portion (e.g., a second
content holding portion) 30 located at the upper end of the
coupling portion 23 and partially embedded in the inlet H23.
[0109] The auxiliary contents holding portion 30 has an upper part
covered with the sealing portion 15 and is coupled with the sealing
portion 15 and keeps auxiliary contents (e.g., second contents) 40
different from main contents (e.g., first contents) held in the
internal space S21 of the receptacle body 20.
[0110] In the present disclosure, the auxiliary contents holding
portion 30 and the sealing portion 15 coupled to the upper part of
the auxiliary contents holding portion 30 may be collectively
referred to as an "auxiliary contents holding device".
[0111] Accordingly, for a storage period of the stored auxiliary
contents 40 and prevention of mixing with the main contents, the
upper part of the open auxiliary contents holding portion 30 may be
covered with the sealing portion 15 so as to be sealed.
[0112] As shown in FIGS. 5 to 6B, the auxiliary contents holding
portion 30 may include a holding part 31 with an open upper part, a
support portion 33 surrounding the holding part 31 to support the
holding part 31, and a mounting portion 35 connected to the support
portion 33 and coupled to an upper end of the coupling portion
23.
[0113] The holding part 31 may have an open upper part and hold the
auxiliary contents (e.g., the second contents) 40 through the open
upper part so as to be kept in storage.
[0114] The holding part 31 has a shape recessed on a lower side,
i.e., a bottom surface, of the receptacle body 20 and may hold the
auxiliary contents 40 therein.
[0115] In addition, since side and lower surfaces of the holding
part 31 are completely blocked, the main contents and the auxiliary
contents 40 held in the receptacle body 20 are not mixed with each
other until before the user drinks the main contents and the
auxiliary contents 40 together by opening the receptacle stopper
10.
[0116] In this case, a possibility of deterioration of the main
contents and the auxiliary contents 40 is significantly reduced
compared to a case where the main contents and the auxiliary
contents 40 kept in the receptacle body 20 are mixed and preserved,
and thus, a preservation period of the main contents and the
auxiliary contents 40 is significantly increased, so that a
distribution period of a corresponding product may be extended.
[0117] The support portion 33 may include a plurality of grates 33
located in a height direction of the receptacle 1a on a side
surface of the holding part 31 and spaced apart from each
other.
[0118] Accordingly, an empty space exists between two adjacent
gratings 331, and the main contents held in the receptacle body 20
may flow out through the inlet H23 through this space.
[0119] Accordingly, the user may easily take the main contents
without removing the auxiliary contents holding portion 30
separately.
[0120] The mounting portion 35 may include a mounting portion body
351 connected to the plurality of gratings 331 of the support
portion 33 and surrounding a portion (e.g., upper portion) of the
holding part 31 and a engaging projection 352 having a shape bent
in a hook shape from an end of the mounting portion body 351.
[0121] Accordingly, the auxiliary contents holding portion 30 may
be positioned on the upper end of the coupling portion 23 of the
receptacle body 20 through the engaging projection 352.
[0122] Therefore, the auxiliary contents holding portion 30 may be
stably located in the inlet H23 of the coupling portion 23 by
virtue of the mounting portion 35.
[0123] In this embodiment, a plurality of gratings 331 are radially
positioned between the holding part 31 and the mounting portion 35
that is positioned spaced apart from the holding part 31 and the
mounting portion 35 spaced apart from the holding part 31 and fully
surrounding an upper portion of the holding part 31, so that the
holding part 31 and the mounting portion 35 may be physically
connected to each other by the gratings 331.
[0124] In this embodiment, a height of an upper end of the mounting
portion 35, that is, a height of an upper end of the engaging
projection 352, and a height of the upper end of the holding part
31 of the auxiliary contents holding portion 30 may be equal, or
alternatively, the height of the upper end of the holding part 31
may be higher than the height of the upper end of the engaging
projection 352. In this case, the upper end of the engaging
projection 352 and the upper end of the holding part 31 are higher
than the upper end of the coupling portion 23.
[0125] Accordingly, the airtight sheet 152 of the sealing portion
15 may be directly adhered or fused to the upper end of the
engaging projection 352 and the upper end of the holding part 31,
and thus, the open upper portion of the auxiliary contents holding
portion 30, as well as the open inlet H23 of the receptacle body
20, may be stopped.
[0126] In this embodiment, adhesion between the support layer 151
and the airtight sheet 152 may be greater than adhesion between the
airtight sheet 152 and the upper end of the holding part 31 and
adhesion between the airtight sheet 152 and the upper end of the
engaging projection 352.
[0127] Therefore, when the cap portion 11 is opened, the airtight
sheet 152 may be separated together with the support layer 151 from
the upper end of the holding part 31 and the upper end of the
engaging projection 352 stably by the protrusion 132 of the cap
portion 11.
[0128] In this way, an example of an assembly process of the
receptacle 1a additionally including the auxiliary contents holding
portion 30 that holds the auxiliary contents 40 may be as
follows.
[0129] First, the assembler positions the auxiliary contents 30 in
the holding part 31 of the auxiliary contents holding portion 30
through the open upper portion of the auxiliary contents holding
portion 30.
[0130] Thereafter, the assembler may attach the sealing portion 15
to an upper part of the auxiliary contents holding portion 30
through a bonding operation or a fusing operation to completely
cover the portion of the open holding part 31 and the portion of
the open coupling portion 23 with the sealing portion 15 to
assemble the auxiliary contents holding device [FIG. 7A].
[0131] Accordingly, the lower surface of the airtight sheet 152 of
the sealing portion 15 may be adhered or fused to the upper end of
the holding part 31 and the upper end of the engaging projection
352 in contact therewith.
[0132] Next, the assembler inserts and positions the engaging
projection 365 of the auxiliary contents holding portion 30 with
the sealing portion 15 mounted thereon in the coupling portion 23
of the receptacle body 20 holding the main contents to couple the
auxiliary contents holding portion 30 to the receptacle body
20.
[0133] Finally, the assembler may couple the cap portion 11 to the
coupling portion 23 of the receptacle body 20, thereby completing
the receptacle 1a in which the main contents and the auxiliary
contents 40 are separated from each other (See FIG. 7B].
[0134] In this state, in order for the user to take the main
contents and the auxiliary contents 40 held in the receptacle 1a,
the user may rotate the cap portion 11 in a corresponding direction
to separate the cap portion 11 from the coupling portion 23.
[0135] As described above, due to the rotational operation of the
cap portion 11, the decoupling operation is performed in turn,
starting from the portion of the sealing portion 15 located most
adjacent to the protrusion 132 according to a lifting phenomenon
based on the protrusion 132 located on the inner side surface of
the cap portion 11, so that the sealing portion 15 may be
completely removed from the coupling portion 23 [FIGS. 7C and
7D].
[0136] Accordingly, the cap portion 11 and the sealing portion 15
may be completely separated from the receptacle body 20, thus
completing the decoupling operation of the receptacle stopper
10.
[0137] Therefore, the user may take the main contents of the
receptacle body 20 discharged between the gratings 331 of the
support portion 33 together with the auxiliary contents 40 exposed
to the outside by the opening of the cap portion 11.
[0138] Next, another example of the receptacle will be described
with reference to FIG. 8.
[0139] In the following embodiments, components having the same
structure as the receptacle shown in FIGS. 1 to 7D and performing
the same function are denoted by the same reference numerals as
those of FIGS. 1 to 7D and a description thereof will be
omitted.
[0140] A receptacle 1b of FIG. 8 may include the auxiliary contents
holding portion 30, and a structure of the other receptacle 1b is
the same as that of the receptacle 1a shown in FIG. 5, except for a
receptacle stopper 10a.
[0141] In the receptacle stopper 10a of this embodiment, as shown
in FIG. 8, components of the receptacle stopper 10a other than a
sealing portion 15a may have the same structure as the receptacle
stopper 10 shown in FIGS. 1 to 3.
[0142] Accordingly, the sealing portion 15a of the receptacle
stopper 10a of the present embodiment may include the support layer
151 and an airtight sheet 152a having an upper surface entirely
adhered to a lower surface of the support layer 151.
[0143] Here, the airtight sheet 152a of this embodiment having a
circular planar shape may be positioned only in part, such as the
middle part of the support layer 151, instead of being in contact
with the entire lower surface of the support layer 151 having a
circular planar shape.
[0144] Due to this, a diameter of the airtight sheet 152a of this
embodiment may be smaller than a diameter of the support layer
151.
[0145] Here, the airtight sheet 152a may be positioned to
correspond to the open upper portion of the holding part 31 of the
auxiliary content holding portion 30 located on the lower side, so
that the airtight sheet 152a may be directly adhered or fused to
only the upper end of the holding part 31, among the upper end of
the holding part 31 and the upper end of the engaging projection
352.
[0146] Therefore, a diameter of the airtight sheet 152a may be
smaller than a diameter of the support layer 151 but may be larger
than a maximum diameter of the holding part 31.
[0147] In addition, a part (e.g., edges) of the sealing portion 15a
may have only the support layer 151.
[0148] Due to this, a thickness of the sealing portion 15a is
different from the sealing portion 15 according to positions. That
is, the part of the sealing portion 15a in which the airtight sheet
152a is located therebelow may have a thickness greater than the
part of the sealing portion 15a in which only the support layer 15
exists. As described above, the sealing portion 15 may have the
same thickness regardless of position.
[0149] Therefore, a height of the upper end of the upper end of the
holding part 31 of the auxiliary contents holding portion 30 may be
lower than a height of the upper end of the engaging projection
352, and here, a height difference between the two upper ends may
be determined depending on the thickness of the airtight sheet
152a.
[0150] In this case, as shown in FIG. 8, the airtight sheet 152a
may be stably adhered to the upper end of the holding portion 30
and the lower surface of the support layer 151 may be stably in
contact with or adhered to the upper end of the facing engaging
projection 352.
[0151] An assembly sequence of the receptacle 1b having the
receptacle stopper 10a of this structure may be the same as the
assembly sequence of the receptacle 1a.
[0152] Therefore, the operator may put the auxiliary contents in
the auxiliary contents holding portion 30, position the sealing
portion 15a above the auxiliary contents holding portion 30, and
subsequently attach or fuse only the upper end of the holding part
31 of the auxiliary contents holding portion 30 to the support
layer 151 to seal the auxiliary contents holding portion 30.
Accordingly, the assembly of the auxiliary contents holding device
in which the sealing portion 15a is mounted on the upper end of the
auxiliary contents holding portion 30 may be completed.
[0153] Thereafter, the operator may couple the auxiliary content
holding portion 30 sealed with the sealing portion 15 to the
coupling portion 23 of the receptacle body 20 holding the main
contents using the engaging projection 352 of the mounting portion
35 of the auxiliary contents holding portion 30 sealed with the
sealing portion 15a to position the auxiliary contents holding
portion 30 in the internal space S21 of the receptacle body 20.
[0154] Finally, the operator may complete the assembly of the
receptacle 1a by coupling the cap portion 11 to the coupling
portion 23 of the receptacle body 20.
[0155] In this way, when the receptacle 1b is completed by coupling
the receptacle stopper 10a to the receptacle body 20, the airtight
sheet 152a is adhered to and located only at the upper end of the
holding part 31, and thus, the airtight sheet 152a may serve as a
cover closing the open holding part 31.
[0156] Accordingly, the holding part 31 is kept completely sealed
by the airtight sheet 152b, so that a storage state of the
auxiliary contents 30 located therein is well maintained and a
possibility in which the main contents and the auxiliary contents
30 held in the body 21 of the receptacle body 20 may be completely
prevented.
[0157] In addition, consumption of the airtight sheet 152b may be
reduced to reduce manufacturing cost of the receptacle.
[0158] Next, another example of a receptacle stopper 10b coupled
with the auxiliary contents holding portion 30 will be described
with reference to FIG. 9.
[0159] As compared with FIG. 8, other components of the receptacle
stopper 10b excluding a sealing portion 15b may have the same
structure as that of the receptacle stopper 10a and the receptacle
body 20 may also be the same as that of FIG. 8.
[0160] Accordingly, the receptacle stopper 10b may include the cap
portion 11, the screw thread 131 and the protrusion 132 located on
the inner side surface of the cap portion 11, and the sealing
portion 15b adhered to the inner upper surface of the cap portion
11.
[0161] The sealing portion 15b of the present embodiment may
include a support layer 151 whose descending position is limited by
the protrusion 132 of the cap portion 11 and an airtight sheet 152a
adhered to a lower part of the support layer 151.
[0162] In this embodiment, the sealing portion 15b may further
include a blocking portion 153 extending from the lower part of the
support layer 151 toward the ground, that is, toward the auxiliary
content holding portion 30. In this case, the blocking portion 153
may be manufactured integrally with the support layer 151, and in
this case, the blocking portion 153 may be formed of the same
material as that of the support layer 151.
[0163] The blocking portion 153 extends from the lower part of the
support layer 151 by a predetermined length downward and is
seamlessly connected and surrounded in a skirt shape along the
circumference of the circular support layer 151. Accordingly, the
blocking portion 153 is a plate having a vertical length and a
circular planar shape with an empty middle part.
[0164] As shown in FIG. 9, the blocking portion 153 may be
positioned such that an outer side surface is in contact with an
inner side surface of the engaging projection 352.
[0165] A maximum diameter, that is, an outer diameter, of the
blocking portion 153 may be larger than a minimum diameter, that
is, an inner diameter of the mounting portion 35. Accordingly, the
blocking portion 153 may be inserted into the internal space of the
mounting portion 35 by a force fitting operation and airtightness
between the blocking portion 153 and the mounting portion 35 may be
increased by the force fitting operation.
[0166] The blocking portion 153 may be released when the sealing
portion 15b is decoupled by an opening operation of the cap portion
11.
[0167] As shown in FIG. 9, a downward extending length of the
blocking portion 153 may be a length in contact with an upper end
of the grating 33 located therebelow.
[0168] Due to the presence of the blocking portion 153, the inner
side of the mounting portion 35 of the sealing portion 15b is
blocked by the blocking portion 153, so that space between the
holding part 31 and the mounting portion 35, as well as an upper
part of the holding part 31, may be sealed.
[0169] Therefore, even if the airtight sheet 152a is not directly
in close contact with the upper end of the mounting portion 35,
leakage of the main contents between the mounting portion 35 and
the support layer 151 may be prevented.
[0170] Therefore, in the receptacle 1c of the present embodiment to
which the receptacle stopper 10b is coupled, the main contents held
in the receptacle body 20 does not flow out even while on the move,
thereby achieving movement convenience and enhancing user
convenience.
[0171] Next, another embodiment of a receptacle stopper 10c coupled
with the auxiliary content holding part 30 will be described with
reference to FIG. 10.
[0172] Also, in this embodiment, other components of the receptacle
stopper 10c except for a sealing portion 15c may have the same
structure as that of the receptacle stopper 10 shown in FIGS. 1 to
3.
[0173] Accordingly, the receptacle stopper 10c of the present
embodiment may include the cap portion 11, the screw thread 131 and
the protrusion 132 located on the inner side surface of the cap
portion 11, and the sealing portion 15c adhered to the inner upper
surface of the cap portion 11.
[0174] As described above, the sealing portion 15c of this
embodiment may be limited in ascending position by the protrusion
132 located on the side surface of the cap portion 11 and may have
a support layer 151c and an airtight sheet 152c adhered to a lower
part of the support layer 151c through adhesion or fusion.
[0175] The sealing portion 15c of this embodiment may additionally
include the blocking portion 153 shown in FIG. 9. Here, the
blocking portion 153 may also be integrally formed of the same
material as that of the support layer 151c.
[0176] The support layer 151c of this embodiment may be located
adjacent to an inner upper surface of the cap portion 11 so as to
be in contact with or near the inner upper surface of the cap
portion 11 and may be in contact with or coupled to an upper end of
the mounting portion 35 located therebelow. To this end, as shown
in FIG. 10, one end of the support layer 151c may be located
between an outer end EP151 of the holding portion 31 and an inner
end of the mounting portion body 351 of the mounting portion 35
adjacent to the end EP151 (i.e., inner end EP152 of the mounting
portion 35) and the other end thereof may be located at an outer
end EP153 of the engaging projection 352 of the mounting portion 35
(i.e., outer end of the mounting portion) or a point passing by the
outer end EP153.
[0177] Accordingly, one end of the support layer 151c may be
located between the holding part 31 and the mounting body 351 of
the mounting portion 35 and the other end of the support layer 151c
may be located between the engaging projection 352 and the inside
of the side surface of the cap portion 11.
[0178] As a result, the support layer 151c may be a thin plate
shape having a donut-like planar shape with a circular empty space
in the middle part, and may be positioned to overlap the
corresponding portions T131 and T132 of the protrusion 132.
[0179] Due to the shape of the support layer 151c, the support
layer 151c may be positioned so as to completely surround the edge
part of the circular sealing portion 15c so as to be in close
contact with or adhered to the upper end of the mounting portion
35, and the support layer 151 may not be located in the middle
part.
[0180] The airtight sheet 152c may be positioned to be connected to
the support layer 151c in the middle part where the support layer
151c is not located in the sealing portion 15c.
[0181] Therefore, as shown in FIG. 10, the airtight sheet 152c may
have a circular planar shape and may be located to completely block
and seal the open middle part of the support layer 151c at a lower
end of the support layer 151c surrounded by the blocking portion
153.
[0182] An upper surface of the airtight sheet 152c may be adhered
to a corresponding portion of the support layer 151c in contact
therewith, and a part of a lower surface of the airtight sheet 152c
may be adhered or fused to the upper end of the holding part 31 in
contact therewith.
[0183] Therefore, a diameter of the airtight sheet 152c may be
equal to a diameter of the part of the support layer 151c
surrounded by the blocking portion 153 and may be larger than an
outer diameter of the holding part 31.
[0184] The blocking part 153 of this embodiment has the same
structure as that of the blocking part described above with
reference to FIG. 9, and due to the presence of this blocking part
153, the main contents held in the receptacle body 20 may be
prevented from flowing out.
[0185] The assembly sequence of the receptacles 1b told having the
receptacle stoppers 10a to 10c, respectively, shown in FIGS. 8 to
10 may be the same as the assembly sequence of the receptacle 1a
described above, and thus a detailed description thereof will be
omitted.
[0186] However, in the receptacle 1d according to the present
embodiment, since the support layer 151c is not positioned on the
airtight sheet 152c adhered or fused with the holding part 31 and
the airtight sheet 152c is exposed, when the sealing portion 15c is
fused to the upper part of the auxiliary contents holding portion
30, a more efficient fusing operation may be performed compared to
the case of the receptacle 1b.
[0187] That is, since the support layer 151c does not exist on the
upper part of the airtight sheet 152c fused with the holding part
31 of the auxiliary contents holding portion 30, the corresponding
part of the airtight sheet 152b in contact with the upper end of
the holding part 31 may be directly irradiated with heat or
ultrasonic waves, and thus, the fusing operation between the
airtight sheet 152c and the upper end of the holding part 31 may be
performed more stably and efficiently.
[0188] Next, a receptacle 1e including another receptacle stopper
10e of this embodiment will be described with reference to FIG.
11.
[0189] Compared with the receptacle stopper 10c of FIG. 10, a
sealing portion 15d includes only support layers 1511 and 1512 and
the blocking portion 153 without an airtight sheet, except for such
a difference from the receptacle stopper 10c, the receptacle 1e of
this embodiment may have the same structure as that of the
receptacle 1d shown in FIG. 10.
[0190] As shown in FIG. 11, the support layers 1511 and 1512 of
this embodiment may include a middle part (e.g., first part) 1511
having a first thickness and adhered to the upper end of the
holding part 31 to cover an upper part of the holding part 31 and
an edge part 1512 having a second thickness greater than the first
thickness, surrounding the middle part 1511, and having a lower
surface in contact with the upper end of the mounting portion
35.
[0191] An upper surface of the edge part 1512 of the support layer
15d is in contact with an edge part of the upper surface of the cap
portion 11 and a lower surface thereof may be adhered or fused to
the upper end of the mounting portion 35.
[0192] In addition, the middle part 1511 may be seamlessly
connected to the edge part 1512 and may be surrounded by the edge
part 1512.
[0193] The middle part 1511 may be adhered to the upper end of the
holding part 31 to cover and seal the open upper part of the
holding part 31.
[0194] In this embodiment, this edge part 1512 and the middle part
1511 are formed of the same material.
[0195] As such, the support layer 15d of this embodiment has
different thicknesses according to positions, so that the middle
part 1511 may replace the airtight sheet 152c to correspond to the
airtight sheet 152c of FIG. 10, and the edge part 1512 may replace
the support layer 151c to correspond to the support layer 151c of
FIG. 10.
[0196] As in the case of FIG. 10, the blocking portion 153 is
located under the edge part 1512 of this embodiment to block the
space between the adjacent gratings 331, thereby preventing outflow
of the main contents of the receptacle body 20 to the outside.
[0197] The edge part 1512 may be positioned in contact with the
upper end of the engaging projection 352 of the auxiliary content
holding portion 30 like the support layer 151c of FIG. 10 and
coupled with the upper end of the engaging projection 352.
[0198] Meanwhile, the middle part 1511 may be adhered or fused to
the upper end of the holding part 31, like the airtight sheet 152c,
thereby blocking the upper part of the open holding part 31 to
isolate the auxiliary contents held in the holding part 31 from the
outside.
[0199] The assembly process of the receptacle 1e having the
receptacle stopper 10d may also be the same as those described
above.
[0200] Therefore, the assembler may position the sealing portion
15d having only the support layers 1511 and 1512 on the auxiliary
contents holding portion 30 holding the auxiliary contents 40 and
subsequently seal the upper part of the auxiliary contents holding
part 30 by the middle part 1511 of the sealing portion 15d through
a bonding operation or a fusing operation to assemble the auxiliary
contents holding device. Here, if necessary, the first part 1511 in
contact with the upper end of the mounting portion 35 may also be
adhered or fused to the upper end of the mounting portion 35
corresponding thereto.
[0201] Next, the assembler couples the auxiliary contents holding
portion 30 to the coupling portion 23 of the receptacle body 20
holding the main contents, and then couples the cap portion 11 to
the coupling portion 23 of the receptacle body 20 through a
rotational operation of the cap portion 11. Accordingly, the
assembly of the receptacle 1e including the auxiliary contents
holding device in the cap portion 11 may be completed.
[0202] In this case, the effect of reducing a manufacturing time
and manufacturing cost of the sealing portion 15d may be
obtained.
[0203] A sealing releasing operation of the sealing portion 15d
according to an opening operation of the receptacle stopper 10d may
be performed by lifting the protrusion 132 in the same manner as
described above.
[0204] In addition, since the sealing portion 15d is formed of a
single layer having only the support layer, the entire sealing
portion 15d may be safely separated from the receptacle body
20.
[0205] In other words, if the sealing portion includes a plurality
of layers containing different materials (e.g., a support layer and
an airtight sheet), the support layer and the airtight sheet may be
separated from each other during the opening operation of the
receptacle stopper, but this problem does not arise in this
embodiment.
[0206] Next, a receptacle if according to another embodiment of the
present disclosure will be described with reference to FIG. 12.
[0207] Compared with FIG. 10, components having the same structure
are denoted by the same reference numerals as those in FIG. 10 and
detailed descriptions thereof will be omitted.
[0208] Compared with FIG. 10, the receptacle if of this embodiment
may be the same as the receptacle 1d shown in FIG. 10, except for a
sealing portion 15f and a cap portion 11f.
[0209] Therefore, a stopper 10f of the receptacle if of this
embodiment may include the cap portion 11f, the screw thread 131
and the protrusion 132 located on the inner side surface of the cap
portion 11f, and the sealing portion 15f adhered to the inner upper
surface of the cap portion 11f.
[0210] The sealing portion 15f may include a support layer 151c,
the airtight sheet 152f partially adhered to a lower part of the
support layer 151c through adhesion or fusion, and the blocking
portion 153, similar to FIG. 10. However, unlike FIG. 10, the
airtight sheet 152f may be formed of a transparent material through
which the auxiliary contents 40 located in the holding part 31 is
visible.
[0211] In addition, the cap portion 11f may include a first part
111 which is a transparent part located to face the holding part 31
on the opposite side of the holding part 31 and a second part 112
which is a support part seamlessly connected to the first part 111,
surrounding the first part 111, and coupled to the coupling portion
23 of the receptacle body 20 using the screw thread 131.
[0212] In this case, the first part 111 may be formed of a
transparent material, and the second part 112 may be formed of the
same transparent material as that of the first part 111 or may be
formed of a translucent or opaque material.
[0213] If both the first part 111 and the second part 112 are
formed of a transparent material, the first part 111 and the second
part 112 may be integrally formed to be seamlessly connected to
each other as shown in FIG. 10.
[0214] However, if the first part 111 and the second part 112 are
formed of different materials (e.g., a transparent material and an
opaque material, the first part 111 and the second part 112 may be
manufactured as two separate parts and assembled with each other as
shown in FIG. 12.
[0215] Compared with the cap portion 11 of FIG. 10, the cap portion
11f may be the same as the cap portion 11 of FIG. 10, except that
the cap portion 11f is divided into two parts 111 and 112.
[0216] As such, the first part 111 of the cap portion 11f facing
the holding part 31 in which the auxiliary contents 40 is located
at the lower part is formed of a transparent material, and the
airtight sheet 152f located under the first part 111 may also be
formed of a transparent material.
[0217] Accordingly, the auxiliary contents 40 located in the
holding part 31 may be visible to the outside through the
transparent airtight sheet 152f and the first part 111, thereby
additionally obtaining an effect that the user may see the
auxiliary contents located in the holding part 31.
[0218] Accordingly, the user may easily check whether the auxiliary
contents 40 is contaminated or spoiled by checking the state of the
auxiliary contents 40, and thus, user reliability may be improved
due to the visual effect of the auxiliary contents 40.
[0219] The cap portion 11f of this embodiment may also be applied
to the cases of FIGS. 5, 8, 9, and 11.
[0220] In this case, in the case of FIGS. 5 and 8, at least a part
of the support layer 151 facing the holding part 31 on the opposite
side and at least a part of the airtight sheet 152 or 152a, that
is, at least a part including a part facing the holding part 31 on
the opposite side of the holding part 31, may all be formed of a
transparent material.
[0221] In the case of FIG. 9, the airtight sheet 152 and at least a
part of the support layer 151 facing the holding part 31 on the
opposite side of the holding part 31, that is, at least a part
including a part facing the holding part 31 on the opposite side,
may all be formed of a transparent material.
[0222] In the case of FIG. 11, the middle part 1511 of the sealing
portion 15d may be formed of a transparent material.
[0223] In this case, an effect that the user may additionally check
the auxiliary contents 40 located in the holding part 31 from the
outside, without removing the airtight sheet, may be additionally
obtained.
[0224] The technical features disclosed in each embodiment of the
present disclosure are not limited only to the corresponding
embodiment, and the technical features disclosed in each embodiment
may be merged and applied to different embodiments, unless
compatible with each other.
[0225] The present disclosure has been described. The present
disclosure is not limited to the embodiments described and the
accompanying drawings, and various modifications and variations may
be made from the viewpoint of a person skilled in the art to which
the present invention pertains. Therefore, the scope of the present
invention should be defined by the equivalents of claims of the
present disclosure as well as the claims.
