Abstract

PURPOSE:To make stirring, mixing and discharging operation of content easier by accommodating a first content and a second content separately before use and arranging to generate an internal pressure when separating an interstructure between said two contents and mixing together by external force. CONSTITUTION:A metal container main body 1 is divided into upper and lower parts with an interstructure 2, and in the upper first chamber A, a first content, consisting of one of two kinds of stock solution and one of two liquid agents to generate pressure when mixed, is filled. On the other hand, in the lower second divided chamber B, a second content, consisting of two other kinds of stock solution and the two other kinds of liquid agents, is filled. By pulling hard a ring 9 at the top of a lever 7 and hitching the same with fingers or the like, a tab 6 is pulled up and broken off at a cut line 4 close by a fixed section 5. As a result, the interstructure 2 is separated to mix up said two contents and necessary discharge pressure is generated.

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 efficiently mixed and agitated during use; The present invention relates to a content mixing and discharging device filled with a first content and a second content that generate internal pressure.

[Conventional technology]

Conventionally, products that utilize reaction products formed by mixing two liquids include foamed polyurethane, epoxy resin adhesives, paints, cosmetics such as hot shaving foam, and quasi-drugs such as hair dye and perm agents. and so on.

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 the mixing to the surface of another object, for example, Japanese Patent Application Laid-Open No. 60-601, filed by the present applicant,
There is one described in JP-A-28842.

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, there is a similar type disclosed in Japanese Patent Application Laid-open No. Sho GO-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.

[Problem that the invention seeks to solve]

However, 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, and in addition, each content has a uniform composition. In order to obtain the reaction product, operations such as stirring with a glass rod are required.

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

[Means for solving problems]

The content mixing container of the present invention includes a container main body, a partition wall for dividing the inside of the container main body into two or more compartments, and an external force provided to form an opening in the partition wall. The container body consists of a separation line that allows a separation line to be formed, and a means for applying an external force from outside the container body to a portion substantially surrounded by the separation line.

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.

[For production]

In the content mixing container, two or more types of content can be separately filled in a single container.

In use, when the separating wall is removed along the separating line using means for applying an external force, a large opening is formed, for example an opening having approximately the same shape as the cross section of the container and having an area of 50 to 90% of the dividing wall.

Therefore, by holding the container body in your hand and shaking it,
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.

To take out the mixed contents, the can may be opened, for example, with a can opener, or a take-out means such as a take-out port and a screw-type cap may be provided in advance.

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 inside of the container into upper and lower parts. Furthermore, even if a separation line that can be easily separated to form a large opening in the partition wall is formed, the separation line will not be broken 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.

[Example] Next, the container and device of the present invention will be explained with reference to the drawings.

The inner part surrounded by the cut 1-1 line (4) (
4a) is equipped with a pull-top type puller (6) that holds the fixed part (5) near the cut line (4), and the puller (6) is attached to the upper part of the container body (1). The end member of <
A bent end portion (8) of a rod-shaped lever (7) that passes through the rod-shaped lever (7) in an airtight manner is engaged. Said puller (6)

As can be easily understood from the above structure, if you hook the ring (9) at the top of the lever (71) with your finger and pull it strongly,
The pull handle (6) is pulled out, and the inner part (4a) of the broken line 11 near the fixed part (5) breaks [-1 line (4), enters the lower J', and then the lever (7) ) is pulled up, the inner part (4a) is cut off along the cut line and pulled upward. A large opening is therefore formed after removal.

Note that the broken line (4) is usually a closed curve, or a relatively closed curve that is partially interrupted at a position opposite to the fixed part (5) or over a length of about I74 of the circumference. It can take various forms as long as it forms a large opening.

In addition, if sealing performance is not so required or if a sufficient sealing means can be provided, a means for transmitting only the tension of a wire or the like and applying an external force may be used in place of the lever (7). sell.

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

The partition wall (2) shown in FIG. 2 has a disk-like shape,
A ring-shaped frame 0 that is fixed so as to surround its outer periphery
1), the inner surface of the outer peripheral wall (1a) of the container body (1) is bonded or pressed. Note that instead of the frame (Ill) shown in FIG. 2, a peripheral wall that stands integrally from the periphery of the partition wall (2) may be employed.

A broken line (4) is formed as a separation line near the outer periphery of the partition wall (2).

A rigid iron (I21) is inserted into the upper end (1b) of the container body (1), and the disk portion (n) at the tip abuts or adheres to approximately the center of the partition wall (2). has been done.

This can be done by strongly pushing or tapping the protruding end 04) of the rod (12) protruding from the container body (1), or by holding the container body (1) upside down and protruding end 04) of the rod 02). The partition wall (
2) can be separated from the separation line to form a large opening.

In addition, in the container of the present invention, the partition wall (2) can be formed by forming a cut line (4) on a single plate, or may be formed separately in advance or by forming a ring-shaped peripheral edge, for example, as shown in FIG. 474 by keeping the partial field and the inner part 07) to be removed resiliently engaged.
may be completed. The separation line in the present invention is a concept that also includes the engaging portion Qa.

FIG. 4 shows another embodiment of the means for applying external force in the container of the invention. In other words, in this case, one compartment (A) is filled with a content made of incompressible fluid such as liquid, and a pressure device 51 consisting of a cylinder (21) and a piston is attached to the container body (1). It is being Further, in the adjacent compartment <13) separated from the compartment (A) by the partition wall (2), some space is left which is not filled with liquid.

In this case, when the internal pressure of one compartment (A) is suddenly increased by pressing or hitting the piston in the direction of the arrow (P), the internal pressure of the other compartment (B) does not increase, so the partition wall (
2) is broken or separated from the separation line (4) to form an opening. In addition, if it is not possible to leave a space that is not filled with liquid in the adjacent compartment (B), pressurizer ■
A pressure reducer having the same configuration as the above may be provided to prevent the internal pressure of the compartment (B) from increasing.

In the containers shown in Figures 1 and 2 above, in addition to shaking the entire container body (1), the contents can be mixed finely by moving or rotating a lever (sword, rod 0'2J, etc.) up and down. .For such purposes, the lever (

) The contents can also be stirred by suctioning them into the container and discharging them.

Next, a case where the mixing container is used as a content mixing and discharging device having a discharging function will be explained. The structure of the container itself is almost the same as that of the mixing container, so a description of the same parts will be omitted, and in particular, the contents filled in the compartment and the means for discharging the reaction product produced by the reaction caused by mixing will be explained. do.

In FIG. 1, the container body (1) used in the content mixing and discharging device (hereinafter referred to as the device) can be made of a pressure-resistant metal m used in ordinary aerosol containers.

-1- The lower end members (1b) and (Ic) each consist of a metal dome 4 and a mounting cap 4, and are caulked to the upper and lower ends of the outer peripheral wall (la).

The lower end member (lc) is equipped with a valve ■, which communicates the inside and outside of the container by pressing from the outside, like those used in ordinary aerosol devices, as a take-out means. A push button ■ is provided.

In addition to the push button ■, a spout is also 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). The container is filled with a first content containing one of two types of liquid agents (hereinafter referred to as the first liquid agent) for three nights.

In the second compartment (B) in the cylindrical member (3), the other stock solution to be mixed (second stock solution) and the other liquid agent (second liquid agent) that generates pressure by mixing are placed. It is filled with a second content that corresponds to the content.

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 above two types of stock solutions and two types of liquid agents may be combined arbitrarily, but if the combination of one stock solution and one liquid agent reacts with each other and causes an inconvenience, they may be combined in the first content. It is preferable that the first content and the second content be separated and allowed to exist independently.

By mixing the first stock solution and the second stock solution, desired products such as foamed polyurethane, epoxy resin stone contact agent, paint, cosmetics such as hot shaving foam, and quasi-drugs such as hair dye and perming agents are produced. Conventionally known two-liquid mixture type stock solutions, such as those that contain

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.

The first content and the second content containing the above-mentioned combination of ingredients are filled into the first compartment and the second compartment, respectively, by a normal method, and when used, the two can be mixed by simply removing most of the partition wall. However, in order to mix and react more uniformly, it is preferable to shake the mixture thoroughly.

In addition, the contents with low specific gravity are filled into the upper compartment.
It is also possible to fill the lower compartment with a content having a large R, and then turn the container body upside down after removing the partition wall.

As a result of the reaction between the first liquid agent and the second liquid agent within the container body, the internal pressure within the container body (1) becomes high, and when the push button is pressed, the reaction product is released to the outside of the container body (1). It is sprayed towards you.

Next, the content mixing device of the present invention will be described in more detail with reference to Examples, but the device of the present invention is not limited to these Examples.

〔Effect of the invention〕

Since the content mixing container of the present invention has a container body divided by a partition wall, two or more types of contents can be filled separately, and when in use, a large opening can be easily opened in the partition wall. Since it can be formed into a single container, it can be mixed and stirred easily, quickly, and uniformly 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. Further, during use, the two types of contents can be easily mixed and stirred to a concentration of 17%, 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 pouring 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 is also possible to eject it in the form of mist by using an appropriately constructed injection port.
