Abstract

PURPOSE:To markedly enhance operability, by a method wherein a container main body is partitioned by a partition wall and two or more kinds of contents are reached when a membrane provided to the opening part of the partition wall is broken by external force and the reaction product is emitted by the generated internal pressure. CONSTITUTION:A content mixing container can fill a single container main body 1 with two or more kinds of contents in a separated state. When an operation rod 6 is pushed in a piercing hole 15 at the time of use, the plate 11 on a membrane 3 is also broken along the inner edge of an opening part 2b to be largely opened. When the membrane 3 is broken, the contents in the container main body 1 are mutually reacted and the pressure in the container main body 1 becomes high to form such a state that the contents can injected at any time. In order to eject the contents, a spout is mounted and then pushed and tilted by a finger to form a gap between a valve body 25 and a valve seat part 21 and the contents can be emitted to the outside through a passing hole 19 and the piercing hole 15.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a content mixing container and a content mixing and discharging device using the container. More specifically, the present invention provides a container in which a first content and a second content can be stored separately before use, and the two can be mixed and stirred efficiently during use, and a The present invention relates to a content mixing and discharging device filled with a first content and a second content that generate internal pressure.

[Prior Art] Conventionally, products that utilize reaction products formed by mixing two liquids include foamed polyurethane, epoxy resin adhesives, paints, cosmetics such as hot shaving foam, hair dye, perm agents, etc. There are many quasi-drugs.

In these products, two liquids are stored separately, and when used, they are mixed in a predetermined ratio. There is no special method for mixing these two liquids; for example, the first content is placed in a container such as a beer bottle, the second content is added thereto, and the mixture is mixed with a glass rod or the like. It is being

In addition, as a mixing and discharging device that can easily apply the reaction product produced by mixing to the surface of other objects, for example, Japanese Patent Application Laid-Open No. 60-28 filed by the present applicant
There is one described in the No. 842 publication.

In this method, the first content is sealed together with the propellant in a pressure-resistant container under pressure, and then an ampoule made of glass or the like filled with the second content is placed in the pressure-resistant container, and the ampoule is crushed. A lever or weight is attached to the container body or inside it.

Furthermore, a similar type is disclosed in Japanese Patent Application Laid-Open No. 60-158073. This product uses an inner container attached to the container body instead of the ampoule, and
It is equipped with a needle for piercing the inner container from the outside of the container body.

[Problems to be Solved by the Invention] By the way, in the method of mixing by force, when mixing the first content and the second content, it is necessary to weigh each content one by one in advance. Moreover, operations such as stirring with a glass rod are required in order to make each content a reaction product with a uniform composition.

Furthermore, if the contents contain a solvent that is harmful to the human body, there is a risk that the harmful solvent will be inhaled when the contents are mixed. Furthermore, it is extremely difficult to handle materials such as foamed polyurethane, which are highly viscous and tend to stick to hands and fingers, and materials that must be poured into molds.

In addition, in the above-mentioned two-component aerosol product, the content containing the propellant inside the outer container is, for example, 5 to 7 kg.
/ cd, so the ampoule or inner container itself needs to have high pressure resistance and gas impermeability. Therefore, in conventional two-component aerosol products, the relatively strong inner container must be painstakingly crushed or punctured from the outside of the container.

Furthermore, since the content of the inner container is also limited, its use as a two-component aerosol product is also limited.

[Means for Solving the Problems] The content mixing container of the present invention includes a container body, a partition wall for partitioning the inside of the container body into two or more compartments, and an opening formed in the partition wall. It consists of a thin film that can be ruptured by an external force and a means for applying an external force to the thin film from outside the container body.

Further, in the contents mixing and discharging device of the present invention using the contents mixing container, the container main body is pressure resistant and includes a take-out means, and the first contents to be mixed with each other are contained in the compartment. and a second content are each filled in an unpressurized state, and when the first content and the second content are mixed, they contain two types of chemicals that react with each other and generate pressure. A configuration is adopted in which each of them is contained separately.

[Function] The content mixing container allows two or more types of contents to be separately filled in a single container.

In use, when the thin membrane is ruptured using means for applying external force, a large opening is formed in the septum.

Therefore, by holding the container body in your hand and making it shallow,
The contents can be quickly and uniformly mixed and stirred. Mixing and stirring can be carried out very easily without using a bee force or other tools such as a glass rod.

Each of the contents mixing and discharging devices is filled with contents in an unpressurized state, that is, at atmospheric pressure. Therefore, manufacturing operations such as filling operations are easy. In addition, high pressure resistance and gas impermeability are used to isolate the contents from each other.
No need to add strength. Therefore, it is possible to employ a partition wall that is relatively thin and has a large area, for example, a partition wall that divides the interior of the container into upper and lower halves. Furthermore, even if a thin film is formed to form a large opening in the partition wall, it will not be ruptured due to the internal pressure difference between the partitions.

To use this product, the same operations as in the case of the mixing container described above are performed to mix and stir the contents to generate a reaction product, and the resulting internal pressure causes the reaction product to be discharged. . Various forms can be adopted for the discharge, such as spraying, foaming, or as a liquid or gas.

The contents mixing container shown in FIG. 1 includes a container body (1),
It is equipped with a partition wall (2).

The container body (1) is constructed by integrally caulking a lid member (1b) and a bottom member (IC) to the upper and lower edges of a cylindrical outer peripheral wall (1a). Note that a sealing plug (1d) is inserted into the center of the bottom member (IC).

The partition wall (2) is a member that vertically divides the interior of the container body (1), and is a cylindrical member with a bottom. A large opening (2b) is formed in the bottom (2a) of this partition (2). The opening end (2C) of the partition wall (2) is connected to the container body (
1) is fixed to the outer peripheral wall (1a) together with the lid member (lb) by caulking.

The container body (1) and partition wall (2) may be made of metal, or if no internal pressure is applied after mixing, synthetic resin sheets,
Various materials can be used, such as paper, laminates thereof, or laminates of paper and metal foil.

A thin film (3) is attached to the bottom (2a) of the partition wall (2) so as to close the opening (2b). This thin film (3
) is easy to break with the rod (5) described later, so aluminum foil, paraffin paper, plastic film, etc. are used. A plate (plate) is attached to the upper surface of the thin film (3) by adhesive or other means. This plate is provided so that the thin film (3) can be completely torn along the entire circumference along the opening (2b). In order to make the plate (II) easier to break, an acute angle part such as a sawtooth edge or a star shape may be formed on the peripheral edge of the plate (II).

A mounting cap 02) is crimped onto the lid member (1b) of the container body (1), and a valve (4) is attached to this mounting cap 02).

This valve (4) is composed of a cylindrical main body (2) and a mounting portion (Q4) disposed around the main body (2). The main body (to) is
It is a member made of synthetic resin such as polyethylene, polypropylene, polyacetal, polyamide, etc., and through holes are formed at the top and bottom. A male screw part 07) for attaching the spout ■ to be described later and a fitting part OF3 for fixing the attachment part a4) are formed at the upper end of the main body (to), and the lower end is for passing the contents. A through hole (to) and a valve seat portion (21) are formed for this purpose. An annular projection protruding inwardly is formed on the inner circumferential surface of the valve seat portion.

The attachment part G41 is a member made of an elastic body such as rubber, and the center part is penetrated so that the main body (2) passes through it. The upper end of the mounting part 04) is formed with a fitting part that closely fits into the fitting part □□□ of the main body ■, and the inner peripheral edge of the mounting cap (12) is fitted to the outer periphery of the central part. A fitting part (24) is formed. The valve (4) is attached to the container body (1) by this fitting part Q4 and the mounting cap 02. In addition, the lower end of the mounting part a4) is a tongue-shaped valve body (to), and the lower surface of the valve body (to) is in close contact with the upper surface of the valve seat part (211). Therefore, the contents do not enter the through hole G under normal conditions.

A rod (5) is inserted into the through hole G of the valve (4). The rod (5) is a means for piercing the thin film (3), and is a relatively long rod-shaped member.

The diameter of the rod (5) is such that it comes into close contact with the inner circumference of the annular protrusion n of the valve (4), and when the rod (5) is in the through hole η, the diameter is such that the contents do not enter into the through hole G. It has become. A plate (to) is attached to the lower end of the rod (9) so that force is applied evenly to the entire plate (4) on the thin film (3). Before use, the rod (5) is positioned slightly above the thin film (3);
) is inserted so that the upper end of the flower is located in the middle of the flower. When no external force is applied, the position is maintained by the frictional force of the annular protrusion.

An operating rod (6) for pushing the rod (5) downward is inserted above the through flower of the valve (4). The operating rod (6) has a grip at its upper end and a piston at its lower end. The piston (2) is made of an elastic material such as rubber, and has an outer diameter approximately equal to the inner diameter of the through hole 6. Note that this operating rod (6) and the rod (5)
This constitutes a "means for applying external force."

In the container of this embodiment, as shown in FIG. 2, when the operating rod (6) is pushed in by hand, the rod (5) is pushed down, and the thin film (3) is broken by the pushing down force of the rod (5).
A large opening is formed in the partition wall (2).

Note that the bottom structure of the container of the present invention is not limited to that shown in FIG. 1, but may also be a bottom member (1e) made of only a plate material as shown in FIG. A mounting cap (1r) may also be used.

Next, in FIG. 1, which describes a content mixing and discharging device using the mixing container, the container body (1) used in the content mixing and discharging device (hereinafter referred to as the device) is a pressure-resistant container used as a normal aerosol container. A metal can or the like can be used.

In the upper first compartment (A) partitioned by the partition wall (2), pressure is generated by mixing with one of the two stock solutions to be mixed (hereinafter referred to as the first stock solution). A first content containing one of two types of liquid agents (hereinafter referred to as the first liquid agent) is filled.

The second compartment (B) in the container body (1) contains a second stock solution to be mixed (second stock solution) and another liquid agent (second liquid agent) that generates pressure by mixing. Contents are filled.

In addition, if the stock solution itself to be mixed functions as the liquid agent, that is, the combination of the first stock solution and the first liquid agent or the second stock solution and the second liquid preparation, or both, are each made of the same liquid. Good too.

The combination of the two stock solutions and the two liquid agents is arbitrary, but if the combination of one stock solution and the other liquid agent reacts with each other and causes problems, they should be used as the first content. It is preferable to separately contain the substance and the second content.

The first stock solution and the second stock solution are mixed to produce desired products such as foamed polyurethane, epoxy resin adhesives, paints, cosmetics such as hot shaving foam, and quasi-drugs such as hair dye and perm agents. Examples include conventionally known two-liquid mixture type stock solutions.

The combination of the first liquid agent and the second liquid agent must be such that when the first content and the second content mix, they react to generate pressure.

Possible mechanisms for generating pressure include one that generates gas through a reaction and thereby increases the internal pressure, and one that generates heat through a reaction and uses that heat to vaporize a low-boiling compound to reduce the pressure.

An example of the former is one in which bicarbonate and acid are combined and carbon dioxide gas is generated by reaction.

An example of the latter is a combination in which a hydrogen peroxide solution and a thiosulfate are reacted to generate reaction heat and a low boiling point compound as described below is vaporized.

In addition to the above, reactions that involve heat generation include hydrogen peroxide and thioglycols, water and finely powdered metals such as activated iron oxide, water and acids or bases, isocyanates and polyols, epoxy compounds and acid anhydrides, etc. However, the apparatus of the present invention is not limited to these, and other types can also be suitably used.

The low-boiling compounds to be vaporized by the exothermic reaction vary depending on the type of content, but include compounds commonly used as solvents, such as dichlorotetrafluoroethane, trichloromonofluoromethane, methylene chloride, butane, and pentane. , a low boiling point solvent such as hexane, heptane, methanol, ethanol, etc. can be used. Furthermore, the low boiling point compound may be produced only by the reaction between the first content and the second content.

Now, when using the device filled with the contents as described above, it is operated as shown in FIG.

When the operating rod (6) is pushed into the through hole, the rod (
5) is pushed down, and 1CI+) on the thin film (3) is also pushed down. As a result, the thin film (3) is torn along the inner edge of the opening (2b) of the partition wall (2), resulting in a large rupture. Note that when the operating rod (6) is pushed in, the piston at the lower end of the operating rod (6) comes into close contact with the annular protrusion of the valve body 03), thereby blocking the outside world from the inside of the container body (1).

When the thin film (3) is ruptured as described above, the container body (1
), the first liquid agent and the second liquid agent react with each other, and the pressure within the container body (1) increases, making it possible to spray the contents at any time.

In order to spray the contents, a spout (7) is attached as shown in FIG. A female threaded portion 4 is formed at the lower end of the spout (7), which is connected to the valve body (
13), it can be attached to the valve (3) as shown in the figure. When the spout ('7) is pushed and tilted with fingers, a gap is created between the valve body 4 and the valve seat (21), so that the contents enter the through hole area through the through hole 09 and are discharged to the outside.

Next, another embodiment of the present invention will be described with reference to FIG.

A valve (2) is caulked with a mounting cap (31) at the upper end of the container body (1) and the partition wall (2). The partition wall (2) is a cylindrical container with an opening (2b) formed in the bottom (2a). and the opening (2b
) is pasted with a thin film (3) so as to cover it.

The valve ring comprises a valve housing (32) into which a stem (33) is inserted via a spring (34). There is a stem rubber (35) between the upper end of the valve housing (32) and the mounting cap (31).
is fixed. A through hole (36) is formed in the stem (33) in the axial direction, and a rod (37) is inserted into the through hole (36).
) has been passed. This rod (37) is a long rod-like member, and the lower end is formed into a conical shape, a pyramidal shape, or any other arbitrary shape so that the thin film (3) can be easily broken and the breach can be made as large as possible. Further, a vertical hole (38) is formed in the upper end portion of the rod (37) in the axial direction, and a through hole (39) is formed in the lower end portion in the radial direction. On the other hand, the upper end of the stem (33) has a through hole (41) extending in the radial direction.
) is formed so that the through hole (41) and the through hole (39) communicate with each other when the rod (37) is pushed into the stem (33). A collar (42) is formed on the rond (37), which restricts the position where the through holes (39) and (41) communicate with each other, and also allows the stem (33) to be pushed in by pushing the rod (37). It is now possible to do so.

A locking portion (42) that slightly protrudes inward is formed at the lower end of the stem (33). Before the rod (37) is pushed in, its tip (37a) is locked by the locking part (42).

When using, push the rod (37) firmly by hand.
The tip (37a) breaks through the thin film (3) and the partition wall (
2) Form an opening. In this way, when the thin film (3) is ruptured, the first liquid agent and the second liquid agent react within the container body (1), the pressure within the container body (1) increases, and the pressure inside the container body (1) increases. The contents will be sprayed and suspended.

To inject the contents, the rod (37) is pushed in a little while the stem (33) is also pushed in a little and the through hole (41) comes off the stem rubber (35), so the through holes (41), (39) ), the contents pass through the rod (37)
It flows into the vertical hole (38) and is injected to the outside.

Although two embodiments of the present invention have been described above, various modifications can be made to the present invention without departing from the gist thereof.

[Effects of the Invention] Since the content mixing container of the present invention has a container body divided by a partition wall, it is possible to separately fill two or more types of contents, and when in use, it is easy to fill the container body with a large partition wall. Since an opening can be formed, mixing and stirring can be easily, quickly, and uniformly carried out in one container. In addition, the user does not have to handle solvent vapor during mixing, and there is no need to spill the liquid.

Furthermore, the content mixing and discharging device of the present invention can separately fill two or more types of content in an unpressurized state. Furthermore, during use, the two types of contents can be easily mixed and stirred, and the reaction product can be discharged under the generated internal pressure. Therefore, the reaction product does not get on your hands, and even when poured into a mold, it can flow directly out of the container body without using any special container or equipment.

Furthermore, if the viscosity of the reaction product obtained is low,
It can also be sprayed in the form of mist by using a spray nozzle with an appropriate structure.
