Description
BACKGROUND
Technical Field
[0001] The present invention relates to a mixing container in which
two different types of substances are mixed together before being
applied with a syringe.
Description of the Related Art
[0002] Mixing containers are currently in use, where a mixing
container may hold two types of contents separately within a single
container, with the contents mixed together when they are used. For
example, in the field of cosmetic products, a mixing container is
being manufactured and distributed in which a gel type base and a
powder are stored individually without mixing, with the base and
the powder mixed together when applied. This form of mixing
container is mainly used in cases where a mixture of the two
different types of contents provides a synergetic effect but where
a premature mixing of the two different contents before the time of
use causes the contents to spoil or exhibit a lowered performance
after a prolonged period of distribution.
[0003] In the case of functional cosmetics, such as essence oils,
etc., a container capable of dispensing an exact amount of a
content may be used, in consideration of the high value of the
content. One device that allows the dispensing of a fixed amount of
content is the syringe. A syringe, which may include an elongated
glass tube with a bulb made of rubber or silicone, etc., formed at
the end, can discharge an exact amount of content and dispense the
content drop by drop.
[0004] A conventional mixing container equipped with a syringe is
disclosed for example in Korean Registered Utility Model No.
0487631. In the mixing container disclosed in the above prior art
document, the syringe may be filled with a content, and the
entrance may be closed with a cap. When the syringe is first used
and is withdrawn from the container body, the cap may be separated,
and the content within the syringe may be discharged.
[0005] The conventional mixing container such as the above entails
the problem that it is difficult to insert the syringe, to which a
cap is coupled, into the inside of the container. Also, with the
conventional mixing container, the cap separated from the syringe
is not removed and may remain inside the container body. This can
be inconvenient to the user and can be undesirable also in terms of
an aesthetic appearance.
SUMMARY OF THE INVENTION
Technical Problem
[0006] An aspect of the present invention, which was conceived to
resolve the problem described above, is to provide a syringe type
mixing container that is simple to manufacture and convenient to

tightly contact the inner perimeter of the insertion head.
[0012] The insertion head can include a head slope member, and the
head slope member can be formed sloping in the direction of the
through-hole.
[0013] The mixing container can further include a syringe that is
configured to be coupled to an upper portion of the first body,
where the syringe can include a nozzle, and when the syringe is
coupled to the first body, the nozzle can press down on the piston
and cause the downward movement of the piston.

the above terms. The above terms are used only to distinguish one
component from another.
[0023] Certain embodiments of the invention will be described below
in more detail with reference to the accompanying drawings. Those
components that are the same or are in correspondence are rendered
the same reference numeral, and redundant descriptions are
omitted.
[0024] FIG. 1 is a cross-sectional view illustrating a mixing
container 100 according to an embodiment of the present invention,
and FIG. 2 is a cross-sectional view illustrating a syringe 190
used with the mixing container 100 illustrated in FIG. 1. FIG. 3 is
a cross-sectional view illustrating the first body 110, the second
body 130, the piston 160, and the lower cap 180.
[0025] Referring to FIGS. 1 to 3, a mixing container 100 based on
this embodiment may include a first content 102 and a second
content 104 filled therein in an unmixed state. The mixing
container 100 can be provided with a syringe 190 as a device for
dispensing the contents, and during the process of the syringe 190
being coupled to the upper portion of the mixing container 100
illustrated in FIG. 1, the piston 160 may be pressed down and moved
by the syringe 190, allowing a mixing of the first content 102 and
second content 104.
[0026] A mixing container 100 according to an embodiment of the
present invention may include a first body 110, a second body 130,
a piston 160, and a lower cap 180. Also, the mixing container 100
based on this embodiment can include a syringe 190 as a device for
dispensing the contents.
[0027] The first body 110 may be a hollow container having a
circular cross section and may have an entrance 114 formed in its
upper portion. A thread 116 may be formed around the entrance 114,
where a syringe cap 194 may be screw-joined to the thread.
[0028] A guide member 108 may be plugged into the entrance 114. The
guide member 108 may include a guide hole 106, and a nozzle 198 of
the syringe 190 may be inserted through the guide hole 106 into the
interior of the first body 110. Since the diameter of the guide
hole 106 may be almost the same as the outer diameter of the nozzle
198, any content (not shown) that has adhered to the outer
perimeter of the nozzle 198 can be removed by the guide member 108
when the nozzle 198 is passed through the guide hole 106.
[0029] A first interior space 120 may be formed within the first
body 110. The first interior space 120 may be filled with the first
content 102. The first interior space 120 may be formed by a
periphery member 118, a head slope member 134 of an insertion head
132, and a center protrusion 136 of the insertion head 132. The
open bottom of the center protrusion 136 can be closed by contact
with the piston 160.
[0030] The first body 110 may be open at the lower end, allowing
the insertion head 132 of the second body 130 to be inserted into
the first body 110.
[0031] A coupling end part 124 may be formed at the lower end of
the first body 110. The coupling end part 124 may be inserted into
a coupling groove 142 formed in the periphery of the second body
130, and as a result the first body 110 and the second body 130 may
be coupled to each other.
[0032] The second body 130 may include an insertion head 132, which
may be inserted into the lower end of the first body 110, and a
lower body 146, which may be exposed to the outside. The second
body 130 may receive the piston 160 movably inserted therein and
may have the lower cap 180 coupled to its lower end.
[0033] The insertion head 132 may be structured to have the shape
of a hollow cylinder with a head slope member 134 formed at the
top. In the center of the head slope member 134, there may be
formed a center protrusion 136. Also, the head slope member 134 may
be formed sloping downwardly in the direction of the center
protrusion 136, whereby the first content 102 filled above the head
slope member 134 can easily flow in the direction of the center
protrusion 136.
[0034] The center protrusion 136 may correspond to a hollow
cylinder formed protruding downwardly from the center of the head
slope member 134. A through-hole 138 may be formed through the
upper end and lower end of the center protrusion 136, thus forming
an open structure. Also, referring to FIG. 1, the outer diameter of
the center protrusion 136 can be formed such that, when the center
protrusion 136 is inserted into the center recess 166 of the piston
160, the outer perimeter of the center protrusion 136 can contact
the inner perimeter of the center recess 166. Thus, the first
content 102 within the center protrusion 136 may not flow into the
second interior space 172.
[0035] The length of the center protrusion 136 may correspond to
the gap between the head slope member 134 and the piston slope
member 162. Therefore, if the length of the center protrusion 136
is great, the gap between the head slope member 134 and the piston
slope member 162 may be great, and hence the volume of the second
interior space 172 may also be large. Conversely, if the length of
the center protrusion 136 is small, then the volume of the second
interior space 172 may be small. Therefore, the length of the
center protrusion 136 can be determined in consideration of the
amount of second content 104 filled in the mixing container
100.
[0036] The diameter of the through-hole 138 formed in the center
protrusion 136 can be formed greater than the outer diameter of the
nozzle 198 of the syringe 190. This can allow the nozzle 198 to
readily pass through the center protrusion 136 and press down on
the piston 160.
[0037] The insertion head 132 may include a head periphery member
140. The head periphery member 140 may be structured to extend down
from the edge of the head slope member 134 with the lower end
connected in a continuous manner with the lower body 146. The outer
perimeter of the head periphery member 140 may contact the inner
perimeter of the first body 110, thereby preventing any leakage of
the first content 102.
[0038] The lower body 146 may have a larger outer diameter than
that of the insertion head 132 and may be connected in a continuous
manner with the lower end of the first body 110. Since the diameter
of the lower body 146 may the same as the diameter of the first
body 110, the exterior of the mixing container 100 can be formed in
a continuous shape with no protuberance.
[0039] The lower cap 180 may be coupled to the lower end of the
lower body 146.
[0040] At the portion where the insertion head 132 and the lower
body 146 are connected, the difference in outer diameter between
the two may form a coupling groove 142. The coupling groove 142 may
be a groove formed in a particular depth along the entire periphery
of the second body 130. Also, in the inner perimeter of the
coupling groove 142, there may be formed a detent groove 144. The
coupling between the first body 110 and the second body 130 may be
completed as the coupling end part 124 of the first body 110 is
inserted in the coupling groove 142 and a protrusion 126 formed in
the periphery of the coupling end part 124 is inserted in the
detent groove 144.
[0041] The piston 160 may be positioned within the insertion head
132 of the second body 130 and, together with the insertion head
132, may form the second interior space 172 that is to be filled
with the second content 104. The piston 160 may move down when
pressed by the user, as a result of which the first interior space
120 and the second interior space 172 may be connected with each
other.
[0042] The piston 160 may include a circularly shaped piston slope
member 162. The piston slope member 162 may have a center recess
166 formed in the center and a piston lip 164 formed on the edge.
The piston slope member 162 may be formed sloping downward towards
the center recess 166 in the middle, whereby the content can be
focused in the direction of the center recess 166.
[0043] The piston slope member 162 may correspond to a part of the
lower boundary of the second interior space 172. That is, the
second interior space 172 may have an upper boundary corresponding
to the head slope member 134 of the insertion head 132, a lower
boundary corresponding to the piston slope member 162 and the
center recess 166, and a boundary in-between corresponding to the
inner perimeter of the insertion head 132.
[0044] The piston lip 164 may be formed protruding upward from the
periphery of the end portion of the piston slope member 162. The
piston lip 164 may move while maintaining tight contact with the
inner perimeter of the insertion head 132, so that the content may
not leak to the lower cap 180.
[0045] The center recess 166 may be a recess formed in the center
of the piston slope member 162 and may be shaped as a hollow
cylinder. The center recess 166 may be open at the top and closed
at the bottom. A piston protrusion 168 may be formed extending from
the lower surface of the center recess 166. When the piston 160 has
not yet moved down, the center protrusion 136 of the second body
130 may be inserted in the center recess 166, whereby the
through-hole 138 formed in the lower end of the center protrusion
136 may remain closed.
[0046] The inner diameter of the center recess 166 may be formed
the same or almost the same as the outer diameter of the center
protrusion 136, so as to prevent any leaking of the first content
102 through the center protrusion 136 before the piston 160 is
moved down.
[0047] The piston protrusion 168 may protrude downward from the
lower surface of the center recess 166 and may be shaped as a
hollow cylinder. The piston protrusion 168 may be partially
inserted in a cap protrusion 186 formed in the center of the lower
cap 180 (see FIG. 1). As the piston 160 is moved downward, the
piston protrusion 168 may be inserted completely into the cap
protrusion 186 (see FIG. 5). In this way, the piston protrusion
168, together with the cap protrusion 186, may serve as a guide
that allows a stable downward movement of the piston 160.
[0048] At the lower end of the piston protrusion 168, a tapered
portion 170 may be formed. The tapered portion 170 may allow the
piston protrusion 168 to more easily be inserted into the cap
protrusion 186.
[0049] The lower cap 180 may be coupled to a lower portion of the
second body 130 to cover the open bottom of the second body 130.
The circularly shaped lower cap 180 may have a cap lip 182 formed
on the edge and a cap protrusion 186 formed in the center.
[0050] The cap lip 182 may be formed protruding upward from the
edge of the lower cap 180 and may be placed in tight contact with
the inner perimeter of the lower body 146 of the second body 130.
The tight contact of the cap lip 182 against the inner perimeter of
the lower body 146 can prevent the lower cap 180 from becoming
detached and prevent the content from leaking out of the mixing
container 100.
[0051] The cap lip 182 may include an outwardly protruding detent
protrusion 184, where the detent protrusion 184 may be inserted
into a groove (no numeral assigned) formed in the inner perimeter
of the lower body 146. Thus, the lower cap 180 may be firmly
coupled to the lower end of the second body 130.
[0052] The cap protrusion 186 protruding upward from the center of
the lower cap 180 may be structured as a hollow cylinder with an
open top. The cap protrusion 186 can be formed in a length that is
the same or almost the same as that of the piston protrusion 168.
Also, the inner diameter of the cap protrusion 186 can be formed
somewhat larger than the outer diameter of the piston protrusion
168. This can allow the piston protrusion 168 to be easily inserted
into the cap protrusion 186.
[0053] A mixing container 100 according to this embodiment can be
provided with a syringe 190 as a device for dispensing the
contents. The syringe 190 may include a syringe cap 194, which may
be screw-joined onto an upper portion of the first body 110, and a
nozzle 198, which may extend downward from the syringe cap 194.
[0054] After the cap 112 coupled to the upper portion of the first
body 110 is removed, the syringe cap 194 can be coupled to the
first body 110 instead of the cap 112. A pressing part 192 may be
formed at an upper portion of the syringe cap 194. The nozzle 198
may be inserted in the center of the syringe cap 194.
[0055] The nozzle 198 may be an elongated hollow tube with its
lower open and its upper end connected with the pressing part 192.
The nozzle 198 can be formed in a length that allows the nozzle 198
to press the piston 160 when the syringe 190 is coupled to the
first body 110. Thus, during the process of the syringe 190 being
coupled onto the first body 110, the nozzle 198 can press the
piston 160 and move the piston 160 downward.
[0056] While the mixing container 100 based on this embodiment is
described using an example in which a syringe 190 is provided as
the dispensing device, the present invention is not limited by the
device for dispensing the contents. Thus, a mixing container 100
based on another embodiment of the present invention can be
provided with any of a variety of other dispensing devices, such as
the spray pump disclosed in Korean Registered Patent No. 1963619,
etc.
[0057] FIG. 4 is a cross-sectional view illustrating the mixing
container 100 with the syringe 190 inserted but with the contents
102, 104 not yet mixed together, and FIG. 5 is a cross-sectional
view illustrating the mixing container 100 of FIG. 4 with the
syringe 190 inserted completely and the contents mixed
together.
[0058] Referring to FIG. 4 and FIG. 5, after the cap 112 is removed
from the mixing container 100 illustrated in FIG. 1, the nozzle 198
of the syringe 190 may be inserted to the inside of the mixing
container 100 through the entrance 114 of the first body 110. Here,
since the piston 160 is inserted onto the center protrusion 136 of
the second body 130, the second interior space 172 may not be
connected with the first interior space 120. Therefore, before the
piston 160 is separated from the center protrusion 136, the first
content 102 may not be mixed with the second content 104.
[0059] When the nozzle 198 is moved down during the process of the
syringe cap 194 of the syringe 190 being screw-joined onto the
first body 110, the lower end of the nozzle 198 may pass through
the center protrusion 136 of the second body 130 and then enter the
center recess 166 of the piston 160 to press the piston 160
downward. Thus, as the piston 160 moves downward, the piston
protrusion 168 may be inserted deeper into the cap protrusion 186.
The downward movement of the piston 160 may disengage the contact
between the center protrusion 136 and the center recess 166 and
thus open the through-hole 138. The opening of the through-hole 138
may allow the first interior space 120 and the second interior
space 172 to be connected with each other, whereby the first
content 102 may flow into the second interior space 172 and be
mixed with the second content 104.
[0060] When the syringe 190 is completely screw-joined to the first
body 110, the end portion of the nozzle 198 may contact the bottom
surface of the center recess 166 of the downwardly moved piston
160. As the piston protrusion 168 may also be completely inserted
into the cap protrusion 186 of the lower cap 180, the piston 160
may not be able to move any further. As illustrated in FIG. 5, even
after the piston 160 is moved completely, the piston lip 164 may
contact the inner perimeter of the insertion head 132, thereby
preventing the mixture of the first content 102 and second content
104 from leaking below the piston 160.
[0061] While the mixing container 100 according to this embodiment
is described using an example in which the nozzle 198 of the
syringe 190 is used to press the piston 160 downward, the present
invention is not limited by the device for pressing down the piston
160. Thus, a mixing container 100 according to another embodiment
of the present invention can press down the piston 160 by using the
nozzle of a spray pump module or a separately provided stick.
[0062] A mixing container 100 based on this embodiment provides the
advantage of convenient use, since screw-joining the dispensing
means, i.e., the syringe 190, moves the piston 160 downward and
allows a mixing of the first content 102 and second content 104.
Also, a mixing container 100 based on this embodiment entails a
simple composition of a first body 110, second body 130, piston
160, and lower cap 180 and therefore provides the advantages of
easy fabrication and assembly.
[0063] While the foregoing provides a description with reference to
an embodiment of the present invention, it should be appreciated
that a person having ordinary skill in the relevant field of art
would be able to make various modifications and alterations to the
present invention without departing from the spirit and scope of
the present invention set forth in the scope of claims below.
