Description

BACKGROUND

1. Field of the Invention

The present invention relates to a heterogeneous contents mixing vessel, and more particularly, to a heterogeneous contents mixing vessel in which first and second vessels storing mutually different contents therein are vertically coupled to each other, and the separated discharge device is connected through a connection member at the same time the coupling of the first and second vessels, so that the first and second vessels can be easily coupled to each other and contents can be prevented from being contaminated due to external foreign substances or—spilled to the outside.

2. Description of the Related Art

In general, there are many cases where two or more different contents are mixed and used in order to multiply the efficacy or effect of cosmetics or medicines contained in a vessel.

However, after the contents are mixed and then the mixed contents are stored in a single vessel, when the mixed contents are put into circulation or kept, a chemical reaction may occur in the vessel to cause the mixed contents to coagulate or precipitate, so that a discharge error may occur or the mixed contents may be discolored or deteriorated.

Thus, according to the related art, after different contents are kept in separate vessels, respectively, the contents are individually discharged and mixed directly when used by a user or the different contents are stored in separate vessels. Then, the contents are used after inlets of the two vessels are opened and the contents are mixed in a separate vessel. However, according to the above-described method, the user is required to directly mix and use the contents stored in a separate vessel, the risk of loss increases and the portability decreases.

Therefore, in recent years, a mixing material vessel has been developed such that different contents may be mixed and used by user's operation when necessary, where the different contents are kept in a single vessel while being isolated from each other and stored in a single vessel.

In the related art, Korean Patent Registration No. 10-1923306 discloses a heterogeneous material mixing vessel. According to the above related art, an inner vessel is inserted and mounted to an outer vessel, each of the vessel is equipped with one of pump sets, and mutually different cosmetics are stored in the outer vessel and the inner vessel, respectively, so that the different kinds of cosmetic contents can be simultaneously discharged, mixed and used with one pumping.

However, since the related art has a structure in which the inner vessel is accommodated together with the cosmetic contents stored in the outer vessel, external foreign substances placed on an outer periphery of the inner vessel enter an inside of the outer vessel in the process of assembling or replacing the inner vessel in the outer vessel, and thus the cosmetic contents stored in the outer vessel are contaminated.

In addition, according to the related art, when the outer vessel and the inner vessel containing mutually different contents are packed separately and then assembled and used by a purchaser, the entire vessel is inserted into an inlet portion of the opened outer vessel and thus the contents stored in the outer vessel overflow to the outside due to the volume or sudden insertion of the inner vessel and contaminate the surroundings, and the assembly is inconvenient.

FIG. 2 is an exploded perspective view of the mixing vessel according to the embodiment of the present invention. FIG. 3 is a sectional view of the mixing vessel according to the embodiment of the present invention.

As shown in the drawing, the mixing vessel according to one embodiment of the present invention may include a first vessel 10, a second vessel 20, a first discharge device 30, a second discharge device 40, and a push button 50.

The first vessel 10 accommodates liquid or gel first contents C1 therein and is formed in a hard cylindrical shape. The first vessel 10 is not limited to the hard cylindrical shape, and may be formed in various shapes and formed of various materials.

As shown in FIGS. 2 and 3, the first vessel 10 includes a first upper vessel 12 and a first lower vessel 14 so that the first lower vessel 14 may be coupled to the first upper vessel 12 while being inserted to a lower inside of the first upper vessel 12. Although the first upper vessel 12 is shown as being screw-coupled to the first lower vessel 14 in the drawing of the mixing vessel according to one embodiment of the present invention, it is not limited thereto, and various coupling schemes, such as undercut coupling, protrusion-and-groove coupling or force fitting coupling, may be applicable.

In addition, an elastic first sealing ring 17a is provided between the first upper vessel 12 and the first lower vessel 14, so that a sealing force between the first upper vessel 12 and the first lower vessel 14 may be further improved.

A support plate 13 may be provided inside the first upper vessel 12, in which the support plate 13 may be formed therein with a first discharge device installation hole 13a to which a first discharge device 30 is installed, and may be formed therein with a second discharge device installation hole 13b to which a part of entire components of the second discharge device 40 is installed.

In addition, first to third vertical guide bars 15a, 15b and 15c may vertically extend from a top surface of the support plate 13 so that vertical movements of the push button 50 may be guided. As shown in FIG. 2, the first vertical guide bar 15a may be formed as a pillar having a cross shape when viewed in a top view, and the second and third vertical guide bars 15b and 15c may be formed as a pillar bent in at least one direction to have an insertion space 15d therein when viewed in the top view.

The first lower vessel 14 may be formed therein with a discharge device accommodation space 14a for accommodating a part of the second discharge device 40, and the discharge device accommodation space 14a is formed at an outside thereof with a contents storage space 14b for accommodating a part of the first discharge device 30 while storing first contents C1. The discharge device accommodation space 14a may be partitioned and separated from the contents storage space 14b by a partition wall 14c, in which the partition wall 14c may have a cylindrical shape with an empty inside.

In addition, a connection groove 16 recessed inwardly of the first vessel 10 may be formed at a lower portion of the first lower vessel 14. In other words, when the first vessel 10 is coupled to the second vessel 20, a second housing 41 and a second suction tube 43 of the second discharge device 40 are automatically connected to each other by a connection member 70 while the connection groove 16 surrounds an outer periphery of an inlet portion 22 of the second vessel 20. In other words, after the components of the second discharge device 40 are separately installed into the first vessel 10 and the second vessel 20, the entire configuration of the separated second discharge device 40 is connected by the connection member 70 when the first vessel 10 is coupled to the second vessel 20.

The connection groove 16 of the first vessel 10 may be formed to be biased to one side from a center of the first vessel 10, and may be screw-coupled while covering the inlet portion 22 of the second vessel 20. The connection groove 16 of the first vessel 10 may be coupled to the inlet portion 22 of the second vessel 20 by various ways in addition to the screw-coupling.

In addition, as shown in FIG. 2, a sealing member 18 may be further provided between the first upper vessel 12 and the first lower vessel 14. The sealing member 18 closes an upper portion of the first lower vessel 14 while at least a part thereof being inserted into an open portion of the first lower vessel 14, and the first discharge device 30 and the second discharge device 40 pass through the sealing member 18.

A sealing plate 18 formed of an elastic material may be further provided between the sealing member 18 and the first upper vessel 12, so that sealing forces of the discharge device accommodation space 14a and the contents storage space 14b may be maintained. In addition, like the sealing member 18, the first discharge device 30 and the second discharge device 40 pass through the sealing plate 19.

As shown in FIG. 3, at least a part of the connection member 70 is fixed while being inserted into the inlet portion 22 of the second vessel 20. The connection member 70 may include an upper connection portion 72 protruding toward an open portion of the inlet portion 22 and connected to the second housing 41 of the second discharge device 40 when the first and second vessels 10 and 20 are coupled to each other, and a lower connection portion 74 protruding toward an inside of the second vessel 20 and connected to the second suction tube 43 of the second discharge device 40, and a coupling portion 76 coupled to the inlet portion 22. A falling-prevention step 76a may be formed on an upper end of the coupling portion 76 of the connection member 70 and seated on an upper end of the inlet portion 22 to prevent the connection member 70 from falling into the second vessel 20.

Meanwhile, at least one air flow hole 78 may be formed in outer sides of the upper connection portion 72 and the lower connection portion 74 of the connection member 70. When second contents C2 are filled inside the second vessel 20, and the connection member 70 having one side coupled to the second suction tube 43 is inserted into the second vessel 20, the air flow hole 78 may serve as a passage configured to discharge air in the second vessel 20 to the outside and serve as a passage configured to introduce air in the outside into the second vessel 20 by the exhausted amount of the second contents C2 upon use.

In addition, a second sealing ring 17b formed of an elastic material may be provided between an upper end of the connection member 70 and the partition wall 14c of the first lower vessel 14.

The first and second sealing rings 17a and 17b and the sealing plate 19 are formed of a soft material, and may be formed of at least one of materials including urethane rubber, natural rubber, elastomer, NBR (nitrile-butadiene rubber) and silicone (silicone), or at least one of elastic materials including polypropylene, polyethylene, acrylonitrile butadiene styrene (ABS), and thermos-plastic elastomer (TPE). The first and second sealing rings 17a and 17b and the sealing plate 19 are not limited to the above-described materials, and may be formed of various materials within a range having a predetermined elasticity.

The second vessel 20 may be coupled to the lower portion of the first vessel 10, and may be formed in a cylindrical shape corresponding to the first vessel 10 for the continuity of appearance of the mixing vessel.

The second contents C2 may be stored in the second vessel 20. The second contents C2 are different from the first contents C1, and may increase the efficacy or effect when used in combination with the first contents C1.

The inlet portion 22 is formed at one side of the second vessel 20, in which the inlet portion 22 is coupled to the first vessel 10 and serves as a filling inlet into which the second contents C2 are filled. The inlet portion 22 may be formed on an outer circumference thereof with a thread so as to be screw-coupled to at thread formed on the connection groove 16 of the first vessel 10. In addition, before the second vessel 20 is coupled to the first vessel 10, the second vessel 20 may be individually packaged, distributed and sold separately from the first vessel 10. In this case, a temporary cover 23 may be coupled to the inlet portion 22 of the second vessel 20.

In addition, the connection member 70 is inserted and fixed inside the inlet portion 22, and the second suction tube of the second discharge device 40 is coupled to the lower portion of the connection member 70 and positioned inside the second vessel 20.

As described above, after the first vessel 10 and the second vessel 20 are separately packaged, distributed and sold, the inlet portion 22 of the second vessel 20 may be inserted and coupled to the connection groove 16 of the first vessel 10 for use. When the upper connection portion 72 of the connection member 70 coupled to the second vessel 20 is inserted into a lower portion of the second housing 41 of the second discharge device 40, the upper connection portion 72 is coupled to the second discharge device 40 separately installed to the first vessel 10 and the second vessel 20, and the connection groove 16 of the first vessel 10 is simultaneously screw-coupled to the outer periphery of the inlet portion 22 of the second vessel 20 while surrounding the outer periphery.

Accordingly, the first vessel 10 can be more simply coupled to the second vessel 20, the first contents C1 can be prevented from being contaminated by external foreign substances in the process of coupling the second vessel 20, and the sealing of the second vessel 20 can be stably maintained even before and after the first vessel is coupled to the second vessel 20.

Although the first vessel 10 is shown as being screw-coupled to the second vessel 20 in the drawing of the mixing vessel according to one embodiment of the present invention, it is not limited thereto, and various coupling schemes, such as undercut coupling, protrusion-and-groove coupling or force fitting coupling, may be applicable.

The first discharge device 30 is installed in the first discharge device installation hole 13a of the first vessel 10 while at least a part of the first discharge device 30 being inserted into the contents storage space 14b of the first vessel 10, and discharges the first contents C1 stored in the first vessel 10 to the outside.

The first discharge device 30 may be a pump configured to discharge a fixed amount of the contents to the outside by a pumping action.

As shown in FIG. 3, the first discharge device 30 may include: a first housing 31 formed at one side thereof with a first contents suction hole 31a; a first suction valve 32 configured to open and close the first contents suction hole 31a of the first housing 31; a first suction tube 33 coupled to a lower portion of the first housing 31 to suck the first contents C1 into the first housing 31; a first housing cap 34 fixedly coupled to an upper portion of the first housing 31; a first piston support 35 formed inside the first housing 31 to vertically move inside the first housing 31; a first piston 36 fitted to an outer side of the first piston support 35 to come into close contact with an inner surface of the first housing 31; a first stem 37 coupled to an upper portion of the first piston support 35; and a first spring 38 configured to elastically support the first stem 37.

The second discharge device 40 is installed in the second discharge device installation hole 13b while a partial component of entire components being inserted into the discharge device accommodation space 14a of the first vessel 10, and remaining components are installed inside the second vessel 20. In other words, after the components of the second discharge device 40 are divided and installed into the first vessel 10 and the second vessel 20, respectively, the entire components of the second discharge device 40 are connected by the connection member 70 so as to be in an operable state at the moment when the first vessel 10 is coupled to the second vessel 20.

The second discharge device 40 discharges the second contents C2 stored in the second vessel 20 to the outside. The second discharge device 40 may be a pump configured to discharge a fixed amount of the contents to the outside by the pumping action.

As shown in FIG. 3, the second discharge device 40 may include: a second housing 41 formed at one side thereof with a second contents suction hole 41a; a second suction valve 42 configured to open and close the second contents suction hole 41a of the second housing 41; a second suction tube 43 configured to suck the second contents C2 stored in the second vessel 20 into the second housing 41; a second housing cap 44 coupled to an upper portion of the second housing 41 to fix the second housing 41 to one side of the second vessel 20; a second piston support 45 formed inside the second housing 41 to vertically move inside the second housing 41; a second piston 46 fitted to an outer side of the second piston support 55 to come into close contact with an inner surface of the second housing 41; a second stem 47 coupled to an upper portion of the second piston support 45; and a second spring 48 configured to elastically support the second stem 47.

The second housing 41, the second suction valve 42, the second housing cap 44, the second piston support 45, the second piston 46, the second stem 47, and the second spring 48 of the second discharge device 40 are installed to the support plate 13 of the first vessel 10, but the second suction tube 43 of the second discharge device 40 is installed inside the second vessel 20 through the connection member 70. In other words, the second housing 41 of the second discharge device 40 is installed to the first vessel 10, the second suction tube 43 of the second discharge device 40 is installed to the connection member 70 so as to be inserted into the first second vessel 20, such that the second housing 41 and the second suction tube 43 of the second discharge device 40 are automatically connected to each other by the connection member 70 when the first vessel 10 is coupled to the second vessel 20.

Meanwhile, the first discharging device 30 and the second discharging device 40 may have a size and a structure different from each other according to the using ratio between the first and second contents C1 and C2 to be pumped. For example, when the first contents C1 discharged by the first discharge device 30 are configured to be discharged, mixed and used more than the second contents C1 discharged by the second discharge device 40, a piston stroke distance and a cylinder inner diameter of the first discharge device 30 may be greater than those of the second discharge device 40.

The push button 50 is coupled to the first vessel 10 so as to move up and down to simultaneously actuate the first and second discharge device 30 and 40, when pressed by a press action of the user.

First and second discharge passages 52a and 52b connected to the first and second discharge device 30 and 40 are formed inside the push button 50, respectively, and first and second discharge ports 54a and 54b are formed at one end portions exposed to the outside of the first and second discharge passages 52a and 52b, respectively.

The first discharge passage 52a of the push button 50 is connected to the first stem 37 of the first discharge device 30 to allow the first contents C1 pumped by the first discharge device 30 to move to the first discharge port 54a, and the second discharge passage 52b is connected to the second stem 47 of the second discharge device 30 to allow the second contents C2 pumped by the second discharge device 40 to move to the second discharge port 52b.

As shown in FIG. 1, the first and second discharge ports 54a and 54b may be formed left and right at outer sides of the push button 50, respectively. In other words, the first discharge port 54a and the second discharge port 54b are arranged parallel and adjacent to each other, so that the first contents C1 discharged from the first discharge port 54a and the second contents C2 discharged from the second discharge port 54b may be easily mixed with each other and used. The positions of the first discharge port 54a and the second discharge port 54b may be variously changed by taking usability, aesthetics, and consumer tastes into consideration.

As shown in FIG. 2, the first to third vertical guide portions 55a, 55b and 55c may downwardly extend inside the push button 50 to guide the vertical movements of the push button 50 together with the first and third vertical guide bars 15a, 15b, and 15c of the first vessel 10. the first vertical guide portion 55a is formed with an insertion groove 55d having a cross shape to which the first vertical guide bar 15a is inserted when viewed in a bottom view.

Accordingly, the first contents C1 stored in the first vessel 10 and the second contents C2 stored in the second vessel 20 are in a state to be discharged together through the first and second discharge device 30 and 40.

Then, as shown in FIG. 6, the vessel cover 60 is removed from the first vessel 10. As shown in FIG. 7, the first contents C1 stored in the first vessel 10 and the second contents C2 stored in the second vessel 20 are discharged together while simultaneously the first discharge device 30 and the second discharge device 40 are simultaneously actuated by pressing the push button 50, and thus the different contents discharged in the above manner are mixed and used.

More particularly, when the first and second discharge device 30 and 40 are pressed together, the first and second stems 37 and 47 and the first and second piston supports 35 and 45 coupled to lower portions of the first and second stems 37 and 47 move downward. Since the first and second pistons 36 and 46 of the first and second discharge device 30 and 40 come into close contact with inner surfaces of the first and second housings 31 and 41, only the first and second piston supports 35 and 45 move downward, thereby generating gaps between the first and second piston supports 35 and 45 and the first and second pistons 36 and 46, and thus discharge passages of the first and second contents C1 and C2 are generated.

Then, the lower ends of the first and second stems 37 and 47, which are moving downward, press the first and second pistons 36 and 46, so that the first and second pistons 36 and move downward together with the first and second piston supports 35 and 45, thereby reducing volumes inside the first and second housings 31 and 41. Accordingly the first and second suction valves 32 and 42 close the first and second contents suction ports 31a and 41a due to discharge pressures in the first and second housings 31 and 41, and the first and second contents C1 and C2 accommodated in the first and second housings 31 and 41 come out between the first and second piston supports and 45 and the first and second pistons 36 and 46, pass through the inside of the first and second piston supports 35 and 45 and the first and second discharge passages 52a and 52b, and are discharged to the first and second discharge ports 54a and 54b, respectively.

Then, as shown in FIG. 8, when the pressure of the push button 50 is released, the first and second stems 37 and 47 and the first and second piston supports 35 and 45 coupled to the lower side of the first and second stems 37 and 47 move upward due to the elasticities the first and second springs 38 and 48 for elastically supporting the first and second stems 37 and 47. At this time, the lower portions of the first and second piston supports 35 and 45 pull the first and second pistons 36 and 46 upward, thereby closing the gaps between the first and second piston supports 35 and 45 and the first and second pistons 36 and 46, so that the first and second piston supports and 45 upwardly move together with the first and second pistons 36 and 46.

Accordingly, vacuum pressures are generated due to increases of volumes inside the first and second housings 31 and 41, and the first and second suction valves 32 and 42 are lifted by the vacuum pressure, thereby opening the first and second contents suction ports 31a and 41a, so that the first and second contents C1 and C2 stored in the first and second vessels 10 and 20 are introduced into the first and second housings 31 and 41, respectively.

Then, the different contents discharged in the above manner are mixed and used.
