Description
TECHNICAL FIELD

The present invention relates to a receptacle for mixing different kinds of materials, and more particularly, to a receptacle for mixing different kinds of materials, wherein an inner receptacle is inserted into an outer receptacle, one of pump sets is mounted in the inner receptacle, and the cosmetic contents different from each other are stored in the inner receptacle and the outer receptacle, while allowing different kinds of cosmetic contents to be used at the same time with one pumping, and to be completely exhausted.


BACKGROUND ART

If two kinds of materials having different ingredients (cosmetics, etc.) are mixed in advance, a problem may occur that these materials deteriorate due to chemical reaction in the mixed state or the performance is remarkably degraded. If the user prepares two containers to store the materials separately and then mixes to use the materials, a problem that causes inconvenience in use occurs.


To solve these problems, a receptacle for mixing different kinds of materials having a structure capable of mixing two kinds of materials by the operation of the user after separately storing two materials in one receptacle is devised and used.



FIGS. 5 and 6 are cross-sectional views of a conventional container for mixing different kinds of materials.


The conventional container for mixing different kinds of materials, as shown in these drawings, includes: a container body portion 111, in which a container storage space 111a is formed and a container opening 111b is formed at an upper end thereof, a shoulder portion 113 coupled to an upper end of the container body portion 111; an inner cap 112 formed integrally with the shoulder portion 113; a container cap 118 coupled to the shoulder portion 113; a push button 114 disposed on the upper side of the inner cap 112; a pressure tube 119 coupled to the bottom surface of the push button 114; a cylinder 150 installed to be communicated with the container storage space 111a; a pumping portion 140 interposed between the cylinder 150 and the push button 114; and an auxiliary storage space portion 160 provided with an auxiliary storage space body portion 161 coupled to the cylinder 150.


The inner cap 112 is formed with a cap hole 112a in a central region thereof.


The inner cap 112 having such a configuration is coupled to the shoulder portion 113 so that the cap hole 112a communicates with the container storage space 111a.


The push button 114 is formed with a “¬”-shaped button flow path 114a which connects the bottom surface and the side surface. The push button 114 can move along the height direction of the container body portion 111.


The pressure tube 119 is formed to be communicated with the button flow path 114a and the cap hole 112a.


The cylinder 150 is formed with a narrowed portion 151 on a bottom region thereof.


The narrowed portion 151 is formed with a through hole 151a on the bottom surface thereof and a cylinder engaging shoulder 151b is formed on the inner surface thereof. The pumping portion 140 includes: a ring-shaped pumping piston 141 installed inside the cylinder 150; an operating shaft 145 installed to enter into the pressure tube 119 through the pumping piston 141; an operating rod 146 installed inside the operating shaft 145; an opening and closing recessed groove portion 147 formed on the lower end of the operating rod 146; a straw support tube 148 installed so that the upper end thereof reaches the bottom surface of the opening and closing recessed groove portion 147 and the lower end thereof passes through the through hole 151a to be exposed to the outside of the cylinder 150; a straw 149 installed inside the straw support tube 148; and a return spring 144 installed to support both ends thereof by the push button 114 and the inner cap 112.


The pumping piston 141 is installed in close contact with the inner surface of the cylinder 150 such that an intermediate storage chamber 150a is formed between the bottom surfaces of the cylinder 150.


In addition, the pumping piston 141 is installed inside the cylinder 150 to be spaced apart from the lower end of the pressure tube 119.


Accordingly, when the pressure tube 119 is descended by pressing the push button 114, the pumping piston 141 descends by itself as much as a distance that the pressure tube 119 is spaced apart from the pumping piston 141, and then can be descended together with the pressure tube 119.


The operating shaft 145 includes a linear operating shaft body portion 145b and a stem 145c formed at the lower end of the operating shaft body portion 145b.


The inner space of the operating shaft body portion 145b becomes the operating shaft flow path 145a.


When ascending, the stem 145c presses the pumping piston 141 upward.


The operating shaft 145 having such a configuration is installed such that the stem 145c passes through the pumping piston 141 and the operating shaft body portion 145b is coupled to the pressure tube 119. In this way, the operating shaft 145 can ascend and descend together with the pressure tube 119.


The opening and closing recessed groove portion 147 is formed with a plurality of opening and closing recessed groove flow path forming protrusions 147a protruding along the longitudinal direction on the upper side of the outer surface thereof.


The opening and closing recessed groove flow path forming protrusions 147a are spaced apart from each other, and thus the opening and closing recessed groove flow path is formed in a space between the opening and closing recessed groove flow path forming protrusions 147a.


The straw support tube 148 is formed with a plurality of support tube flow path forming protrusions 148a protruding along the longitudinal direction on the upper side of the outer surface thereof.


The support tube flow path forming protrusions 148a are spaced apart from each other, and thus a support tube flow path is formed in a space between the support tube flow path forming protrusions 148a. A return spring 144 is installed such that both ends thereof are supported by the push button 114 and the inner cap 112.


The auxiliary storage space portion 160 is provided with an auxiliary storage space sealing plate portion 162 formed at the lower end of the straw support tube 148 in addition to the auxiliary storage space body portion 161.


The auxiliary storage space sealing plate portion 162 is formed to be disposed perpendicularly to the longitudinal direction of the straw support tube 148.


The auxiliary storage space body portion 161 has a structure capable of forming a sealed space in cooperation with the straw supporting tube 148, the auxiliary storage space sealing plate portion 162, and the cylinder 150.


The operation of conventional containers for mixing different kinds of materials having such a structure will be described with reference to FIGS. 7 and 8. For convenience of explanation, it is assumed that the liquid cosmetics are stored in the inner space of the container body portion 111, that is, in the container storage space 111a, and the powdered cosmetics are stored in the auxiliary storage space portion 160.


When first pressing the push button 114 downward, the pressure tube 119 descends by itself as much as a distance spaced apart from the pumping piston 141, and then the pressure tube 119 descends together with the pumping piston 141. When pressing the push button 114, elastic force is accumulated in the return spring 144.


When the pressure tube 119 descends, the opening and closing recessed groove portion 147 and the straw support tube 148 descend as well. Here, the opening and closing recessed groove portion 147 is descended such that the opening and closing recessed groove flow path forming protrusions 147a cross the cylinder engaging shoulder 151b.


When the straw support tube 148 descends, the auxiliary storage space sealing plate portion 162 also descends to cross the lower end of the auxiliary storage space body portion 161.


When the auxiliary storage space sealing plate portion 162 descends, powder cosmetics stored in the auxiliary storage space portion 160 and liquid cosmetics stored in the container storage space 111a are mixed (see FIG. 7).


Next, when releasing the pressure applied to the push button 114, the push button 114 ascends to the original position by elastic force accumulated in the return spring 144. When the push button 114 ascends, the operating shaft 145 and the pumping piston 141 ascend and the operating shaft flow path 145a is closed by the pumping piston 141.


In addition, when the operating shaft 145 ascends, the operating rod 146 and the opening and closing recessed groove portion 147 also ascend. Here, the ascending distance of the operating rod 146 and the opening and closing recessed groove portion 147 is limited by the engagement action between the opening and closing recessed groove flow path forming protrusions 147a and the cylinder engaging shoulder 151b.


When the operating rod 146 and the opening and closing recessed groove portion 147 ascend, the groove bottom surface of the opening and closing recessed groove portion 147 and the upper end of a straw 149 are spaced apart from each other, and thus the container storage space 111a is connected to the intermediate storage chamber 150a through the straw 149, the opening and closing recessed groove flow path which is formed in a space between the opening and closing recessed groove flow path forming protrusion 147a, and the support tube flow path which is formed in a space between the support tube flow path forming protrusions 148a.


As such, the operating shaft 145 ascends in the state in which the container storage space 111a is connected to the intermediate storage chamber 150a, so that a negative pressure is generated in the intermediate storage chamber 150a and the mixed cosmetics in the container storage space 111a flow into the intermediate storage chamber 150a through the support tube flow path (see FIG. 8).


Next, when pressing the push button 114 downward, the pressure tube 119 descends by itself as much as a distance spaced apart from the pumping piston 141, and then the pressure tube 119 descends together with the pumping piston 141.


During the pressure tube 119 descends as much as a distance spaced apart from the pumping piston 141, the operating shaft flow path 145a is communicated with the intermediate storage chamber 150a.


When the operating shaft flow path 145a is communicated with the intermediate storage chamber 150a, the mixed cosmetics in the intermediate storage chamber 150a pass through the operating shaft flow path 145a, the pressure tube 119, and the button flow path 114a sequentially to be discharged to the outside.


On the other hand, when the push button 114 descends, elastic force is accumulated in the return spring 144.


Next, when releasing the pressing force to the push button 114, the push button 114 ascends to the original position by elastic force accumulated in the return spring 144.


When the push button 114 ascends, the operating shaft 145 and the pumping piston 141 ascend and the operating shaft flow path 145a is closed by the pumping piston 141.


When the operating shaft 145 ascends, a negative pressure is generated in the intermediate storage chamber 150a, and the mixed cosmetics in the container storage space 111a flow into the intermediate storage chamber 150a.


A conventional container for mixing different kinds of materials having the above-described configuration is disclosed in a Utility Model Application No. 2002-15583 (Title of Utility Model: MIXED COSMETIC CONTAINER).


However, according to the conventional container for mixing different kinds of materials, since different kinds of materials are mixed by a method of descending the auxiliary storage space sealing plate portion 162 though the operating rod 146, the opening and closing recessed groove portion 147, and the straw support tube 148, which are installed in the cylinder 150, there was a problem that the structure for mixing different kinds of materials is complicated and the product assembly is difficult.


Since the operating rod 146, the opening and closing recessed groove portion 147, and the straw support tube 148 are disposed inside the cylinder 150, there was a problem that the size of the intermediate storage chamber 150a is reduced due to the structure for mixing different kinds of materials.


DISCLOSURE
Technical Problem

The present invention is invented to meet the needs of the conventional art, and it is an object of the present invention to provide a receptacle for mixing different kinds of materials, wherein an inner receptacle is inserted into an outer receptacle, one of pump sets is mounted in the inner receptacle and the outer receptacle, respectively, and cosmetic contents different from each other are stored in the inner receptacle and the outer receptacle, while allowing different kinds of cosmetic contents to be used at the same time with one pumping, to be mixed with different pumping amounts, and to be completely exhausted.


Technical Solution

A receptacle for mixing different kinds of materials according to a first embodiment of the present invention, includes: an outer receptacle (10) for holding cosmetic contents; a shoulder member (20) of a cylindrical member having open upper and lower portions, which is screw-coupled to an upper opening portion (11) of the outer receptacle (10); a pump coupling member (50) of a disk-shaped member coupled to the inner circumference of the shoulder member (20), which couples a first pump set (30) and a second pump set (40) side by side; an inner receptacle (60) of a cylindrical member, an upper flange (61) of which is placed between a lower surface of the pump coupling member (50) and an upper surface of the upper opening portion (11) of the outer receptacle (10), which is partitioned into a first and a second space portions (62, 63), into which a first and a second pump sets (30, 40) are inserted from the upper part, respectively, in which the lower part of the first space part (62) is opened and the lower part of the second space part (63) is closed; a button member (70) of a cylindrical member, of which the upper part inserted into the upper opening portion of the shoulder member (20) is closed and the lower part thereof is opened, which is coupled to discharge the cosmetic contents to the outside by pressing to operate the first and the second pump sets (30, 40) while receiving them in the lower part; a cover member (80) coupled to the upper outer circumference of the shoulder member (20) to cover the button member at the upper part of the button member (70); and an internal piston for the inner receptacle (90) which is a member inserted into the lower part of the inner receptacle (60), which lifts up the cosmetic contents in the inner receptacle (60) to be completely exhausted when the pump is pumped by the first and second pump sets (30, 40).


Advantageous Effects

According to a receptacle for mixing different kinds of materials of the present invention, the second pump set is configured by inserting a cylindrical cylinder member into the inner circumference of the second pump housing so that a smaller amount of cosmetic contents are pumped than the cosmetic contents pumped by the first pump set. That is, since the pumping amounts of the cosmetic contents in the inner receptacle is less than the pumping amounts of the cosmetic contents in the outer receptacle, it is useful when the dilution ratio between the cosmetic contents in the outer receptacle and the cosmetic contents in the inner receptacle is 2:1 or 3:1, that is, when the pumping amounts of the first and the second pump sets are different.


In addition, the cosmetic contents in the inner receptacle 60 are completely pumped by the first and the second pump sets 30, 40 and thus are exhausted as the internal piston for the inner receptacle 90 ascends, thereby not wasting the cosmetic contents.

Inlet holes 31b, 41b through which external air flows are formed at upper side surfaces of the first and the second pump housings 31, 41, respectively.


An air hole 43a is formed at an upper outer circumference of the cylinder member 43 in a cylindrical shape to be communicated with an inflow hole 41b of the second pump housing 41 so that air is introduced into the cylinder.


A shoulder cover member 22 is formed on the upper part of the shoulder member 20 in the same manner as the outer shape of the shoulder member 20 to cover it. In addition, a button cover member 72 is formed even on the upper part of the button member 70 in the same manner as the outer shape of the button member 70 to cover it.


On the upper part of the button cover member 72, a receptacle cover member 80 of a cylindrical member with the lower part opened is installed, the bottom surface of which is supported on the flange 22a of the shoulder cover member 22 and coupled to a coupling protrusion 22b formed on the outer circumference of the shoulder cover member 22 to cover the shoulder cover member 22.


The lower parts of the stepped portions 31a, 41a of the first and the second pump housings 31, 41 are connected with hoses 31c, 41c for sucking the cosmetic contents, respectively.


The receptacle for mixing different kinds of materials according to a first embodiment of the present invention configured as described above includes two pump sets, that is, the first pump set 30 is configured to pump the cosmetic contents in the outer receptacle 10 and the second pump set 40 is configured to pump the cosmetic contents in the inner receptacle 10 so that different kinds of cosmetic contents can be mixed and used simultaneously with one pumping.


In addition, the second pump set 40 is configured by inserting a cylindrical cylinder member 43 into the inner circumference of the second pump housing 41, so that the cosmetic contents are pumped less than the cosmetic contents pumped by the first pump set 30. That is, the pumping amount of the cosmetic contents in the inner container 60 is less than the pumping amount of the cosmetic contents in the outer receptacle 10.


For example, when the dilution ratio of the cosmetic contents in the outer receptacle 10 and the cosmetic contents in the inner receptacle 60 is 2:1 or 3:1, that is, it is useful when the pumping amount of the first and the second pump sets 30, 40 is different.


In addition, as the cosmetic contents are exhausted, the inner piston for the inner receptacle 90 inserted in the lower part of the inner receptacle 60 ascends and exhausts the cosmetic contents to the upper part.


As FIG. 2 is a type in which a hose 41c for inhaling the cosmetic contents is connected only to the lower part of the stepped portion 41a of the second pump housing 41, the inner piston for the inner receptacle 90 is inserted only in the first space portion 62 of the inner receptacle 90.


As FIG. 3 is a type in which a hose 31c for inhaling the cosmetic contents is connected only to the lower part of the stepped portion 31a of the second pump housing 41, the inner piston for the inner receptacle 90 is inserted only in the second space portion 63 of the inner receptacle 90.


As FIG. 4 is a type in which hoses 31c, 41c are not connected to the lower part of the stepped portions 31a, 41a of the first and second pump housings 31, 41, the inner piston for the inner receptacle 90 is inserted in the first and the second space portions 62, 63 of the inner receptacle 90, respectively.


As the cosmetic contents in the inner receptacle 60 are pumped by the first and the second pump sets 30, 40, and thus the inner piston for the inner receptacle 90 ascends, the cosmetic contents are completely pumped to be exhausted. By completely exhausting as described above, the cosmetic contents are not wasted.


As described above, while the present invention has been described with reference to exemplary embodiments thereof in the detailed description, it is obvious that the techniques of the present invention are easily modified by those skilled in the art, and these modified embodiments will be included in the technical idea described in the claims of the present invention.
