  An object of the present invention is to provide a mixed discharge container in which two or more kinds of contents are not mixed before use but can be mixed immediately before use to prepare a desired discharge object. is there.

  The means for solving the problem has a bottom part that can be broken by pressing, contains a first container for containing a first content, a second content, and the first container contains the first container. A second container having a break-through means that breaks through the bottom part by pressing, and an operation head that is attached to the first container and includes a pump mechanism; It is a two-component mixing container characterized by having.

  In the mixed discharge container according to the present invention, the first contents are accommodated in the first container, and the second contents are accommodated in the second container. The first content and the second content are mixed with each other to have a desired property, characteristic, and form, for example, a mixture of the first content and the second content, Mixing the reaction product containing the new reaction product, the first content and the second content by reacting the component in the first content with the component in the second content As long as a new content or the like having a specific color, taste, fragrance, viscosity or the like can be formed, there is no restriction on the nature, type, content, and the like.

  The mixed discharge container according to the present invention operates as follows. The second container attached to the bottom of the first container is pressed toward the bottom of the first container, and the second container is raised. When the second container rises, the breakthrough means rises and approaches the bottom of the first container. As the second container still rises, the breakthrough means contacts the bottom of the first container. When the second container further rises, the breakage means breaks through the bottom due to the pressing force of the second container, the vicinity of the tip of the breakthrough means protrudes into the first container, and a through-hole is formed at or near the broken bottom. It is formed. When the through-hole is formed, the first content stored in the first container flows into the second container via the through-hole due to gravity or pressure and is stored in the second container. The second content is pushed into the first container, and the first content and the second content are mixed. When the first contents and the second contents are mixed, a simple mixture or reaction product that is a desired discharge target is prepared.

  After the desired discharge target is prepared, when the operation head is moved up and down, the discharge target obtained by mixing in the container through the flow path leading from the control head into the container is discharged from the control head. Is done. The discharge target discharged from the operation head is in the form of, for example, a mist, liquid, foam, or paste depending on the structure of the mixed discharge container or the nature of the contents.

  According to this invention, the first contents stored in the first container and the second contents stored in the second container can be obtained by a simple operation of moving the second container up and down. Provided is a mixed discharge container that can mix and therefore discharge discharged objects that do not last after mixing, discharged objects that are desired to be used within a predetermined time after mixing, etc. be able to.

  The first contents stored in the first container are not particularly limited, and may be various liquids, various emulsions, various suspensions, various powders or the like that are usually used for cosmetics, medical use, or industrial use. That's fine. The second content stored in the second container is stored separately from the first content and mixed with the first content immediately before use, or by a catalyst or the like. It is preferable that the chemical reaction with the first liquid is promoted. Such second contents include, for example, oxygen, light, liquids that are unstable over time, emulsions, suspensions or powders, or liquids, emulsions, suspensions whose efficacy changes depending on the content of moisture or the like. Examples thereof include turbid liquids and powders, and more specifically, for example, vitamins and enzymes.

  The mixed discharge container according to the present invention includes a first container, a second container, and an operation head.

  The first container has a bottom that can be broken by pressing, and is formed in a shape that can accommodate the first contents. The shape of the first container is, for example, a bottomed body and a bottomed body having a cylindrical body in which a cross-sectional shape perpendicular to the central axis passing through the center of the bottom is formed from the bottom to the top. A cylindrical body, a bottom body, and a cylindrical body formed so that a cross-sectional shape perpendicular to the central axis passing through the center of the bottom is the same from the bottom to a predetermined height, and a tapered shape from the cylindrical body And a bottomed cylindrical body having a shoulder portion formed so that the cross-sectional shape is reduced and a neck portion formed on the upper portion of the shoulder portion. The cross-sectional shape orthogonal to the central axis can be formed into, for example, a circle, an ellipse, or a polygon. Such a shape of the first container is an example, and the shape of the container known by the names of a spray container, a nozzle container, and the like can be directly adopted as the shape of the first container in the present invention. The opening provided in the first container may be, for example, an opening that opens upward near the upper end, and is an opening that is formed in the neck and has an area smaller than the bottom surface. It may be.

  Examples of the material forming the first container include synthetic resin, metal, glass, ceramics, and the like, and are not particular about transparent materials and opaque materials. Examples of the synthetic resin include polypropylene, acrylic-butadiene-styrene copolymer, polyethylene terephthalate, acrylonitrile-styrene copolymer, and the like. Among these, since polyethylene terephthalate has high transparency and oxygen permeability and a high-class feeling, it is desirable to store a discharge object unstable to oxygen or a discharge object with high value in a mixed discharge container, Since polypropylene is low in cost, it is desirable to store a mass-produced discharge object or a discharge object with a low value in a mixed discharge container.

  The bottom of the first container is formed so as to be capable of being broken by pressing. The bottom portion is broken by a pressing force provided by a breakthrough means provided in a second container described later, and a through-hole penetrating the first container and a second container described later is formed at or near the bottom portion. It is a part that can. The bottom part that can be broken by pressing may be formed so that the whole bottom part in the first container can be broken, or a part of the bottom part in the first container can be broken. The breakable bottom portion only needs to have a strength that is not damaged by the first contents accommodated in the first container. For example, an opening is provided in the bottom portion, and the opening is closed with a sheet or the like. Structure, circular structure formed by an annular groove drilled in the bottom, circular thin wall formed in the bottom, an opening in the bottom, and a disk-like member that closes the opening is fixed to the bottom with a seal or the like Etc. The sheet can be formed of a material that can be easily broken by breakthrough means described later, for example, a metal foil such as an aluminum foil, paper, a plastic sheet, a composite material using these. As the seal, an adhesive seal in which an adhesive is applied to one surface of a sheet formed of the same material as the sheet can be used.

  The first content stored in the first container includes, for example, a liquid, emulsified or fine solid content dispersed in a liquid, and more specifically, Examples include fluids such as various liquids for makeup, medical use, and industrial use, various emulsions, and various suspensions.

  A second container is attached to the bottom of the first container. The second container is mounted on the bottom of the first container so that the second contents accommodated in the second container cannot leak, so that the second container is movable in the vertical direction of the first container. The For example, a protrusion is provided on each outer surface of the first container and the second container, and each protrusion is placed in a liquid-tight state on each outer surface of the first container and the second container. The second container has a slidable surface while maintaining a liquid-tight state with respect to the outer surface of the first container, and the outer surface and the surface are in a liquid-tight state. In this way, by fixing the second container, the second container can be mounted on the bottom of the first container so that the second contents cannot leak out.

  The second container has breakthrough means that can break through the bottom of the first container by pressing. The breakthrough means rises as the second container rises, and is formed so as to be able to break through the bottom by breaking the breakable bottom of the first container or lifting the bottom. The second container is formed into a rod-like body, a cone, a wall-like body or the like extending upward from the inner bottom surface. The breakthrough means is provided at a position where a tip portion thereof faces a breakable bottom portion of the first container. This breakthrough means is preferably formed so as to break through the bottom of the first container as much as possible.

  This second container contains the second contents. This second content is a substance that can be mixed with the first content accommodated in the first container to become a discharged material suitable for use, and is stored separately from the first content. It is preferable that the first content is mixed immediately before use, or the chemical reaction with the first liquid is promoted by a catalyst or the like. The second content may be a liquid such as a solution, an emulsion, and a suspension, or may be a fine powder and a granule having fluidity. The second content contains an unstable component, a component unstable to oxygen, light, etc., a component whose efficacy changes depending on the content of moisture, and the like with respect to the first content. be able to. The second content may be a single component or a mixture of two or more components. The internal volume of the second container depends on the type of the second content accommodated in the second container, the type and characteristics of the discharge material to be generated by mixing with the first content, etc. It is determined appropriately.

  The operation head is configured to be attachable to an opening provided in the first container and to be movable up and down. The operation head includes a nozzle body including a nozzle that discharges an object to be discharged prepared from the first contents and the second contents in the first container to the outside, and the inside of the first container. And a flow path for introducing the discharge target prepared in (1) to the nozzle. As long as the flow path in this operation head employ | adopts the structure which can guide | emit the to-be-discharged object prepared in the said 1st container to the said nozzle, it can take various structures.

  The mechanism that enables the operation head to move up and down is, for example, by moving up and down a nozzle body that joins a flow path having one end arranged near the bottom of the cylinder, thereby sucking out an object to be discharged and discharging from the nozzle. Various mechanisms can be employed as long as the mechanism can discharge an object. As a simple mechanism, in the middle of the flow path to the nozzle, a piston and a cylinder that fits the piston, and when the nozzle is lowered, the discharged object in the cylinder is discharged from the cylinder to the nozzle, and the nozzle is raised. And a discharge mechanism that closes when the nozzle is lowered, and a suction mechanism that sucks the discharged material into the cylinder when the nozzle is raised. In the middle of the path, a piston, a cylinder that fits this piston, a discharge valve in the cylinder that is discharged when the nozzle is lowered, and a nozzle that is closed when the nozzle is raised, and the nozzle is lowered When the nozzle is raised, the suction valve sucks the discharged object into the cylinder. When the nozzle is lowered, the discharged object in the cylinder and air are mixed to form bubbles. Foaming pump mechanism or the like comprising a foam forming section that can be cited. In addition to these pump mechanisms, for example, there is a spray pump mechanism that can spray a generally known object to be sprayed in a spray pattern.

  The mixed discharge container having the above configuration operates as follows. As an initial state, this mixed discharge container is as follows. That is, the operation head is attached to the opening provided in the first container, and the second container is second on the bottom of the first container so that the breakthrough means faces the breakable bottom of the first container. It is in a state where the contents of can not be leaked. The first container stores the first contents, and the second container stores the second contents. In this initial state, since the bottom of the first container is not broken, the first contents stored in the first container and the second contents stored in the second container are mixed. There is nothing.

  In using a mixed discharge container to discharge a desired discharge object, the second container mounted on the bottom of the first container is pressed toward the bottom of the first container, and the second container is Raise. At this time, since the second container is attached to the first container so that the second contents cannot leak, the second contents will not leak even while the second container is rising. . When the second container rises, the breakthrough means also rises. Therefore, when the second container rises, the breakthrough means also rises and approaches the bottom of the first container. As the second container still rises, the breakthrough means contacts the bottom of the first container. When the second container further rises, the breakage means breaks through the bottom due to the pressing force of the second container, the vicinity of the tip of the breakthrough means protrudes into the first container, and a through hole is formed at or near the broken bottom. Is done. When the through-hole is formed, the first content stored in the first container flows into the second container via the through-hole due to gravity or pressure and is stored in the second container. The second content is pushed into the first container, and the first content and the second content are mixed. When rapid mixing is desired, the first contents and the second contents are quickly mixed by forcibly shaking the entire mixing and discharging container.

When the pressing force exceeds a predetermined force, the connecting rib 59 connecting the bottom surface 54 and the cylindrical support portion 52 is cut, and the annular engagement protrusion 40 is connected to the first annular engagement. The bottomed cylindrical body 51 in the fixed second container 50 is moved over the protrusion 57a. Even if the bottomed cylindrical body 51 becomes movable, the contact state between the cylindrical portion 31 and the cylindrical portion 53 is maintained, so that the second content 44 does not leak out. In the mixed discharge container 1, when the connecting rib 59 is cut, the cylindrical support portion 52 drops off (see FIG. 3).

  When the movable bottomed cylindrical body 51 is further pressed in the same direction, the outer peripheral surface 55 rises along the inner peripheral surface 39, and the bottomed cylindrical body 51 rises. When the bottomed cylindrical body 51 rises, the breakthrough means 60 also rises, and the breakthrough means 60 approaches the fracture portion 32. When the bottomed cylindrical body 51 still rises, the tip portion 62 of the breaking means 60 comes into contact with the breaking portion 32. When the bottomed cylindrical body 51 is further raised, the front end portion 62 of the breaking means 60 breaks through the breaking portion 32 and lifts the breaking portion 32 by the pressing force that presses the bottomed cylindrical body 51. When the bottomed cylindrical body 51 rises until the tip of the cylindrical portion 53 contacts the lower surface of the ceiling portion 33 and the upper surface of the bottom surface 54 contacts the lower surface of the flange portion 34, as shown in FIG. Further, the third annular engagement protrusion 57c gets over the first annular engagement protrusion 57a, and the vicinity of the distal end portion 62 of the breaking means 60 protrudes into the first container 10, and the broken portion 32 or its vicinity broken. The state where the through-hole 63 is formed is maintained. When the through-hole 63 is formed, the first contents 16 accommodated in the first container 10 flow into the second container 50 via the through-hole 63 due to gravity or pressure, and the second The second contents 44 contained in the container 50 are pushed into the first container 10, and the first contents 16 and the second contents 44 are mixed. When rapid mixing is desired, the first contents 16 and the second contents 44 are quickly mixed by forcibly shaking the entire mixing and discharging container 1.

  In this way, when the first contents 16 and the second contents 44 are mixed and a desired discharge object is prepared, the operation head 70 is operated to remove the discharge object from the nozzle 71. Can be injected.
