Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a novel container for storing and mixing multi-component liquids (including pastes). Specifically, it has a function of dividing and storing a multi-component liquid between polymerized sheets, and particularly, when storing and mixing a small amount of multi-component liquid, leaving a large amount of liquid in the container. It is a liquid mixing container that can be taken out without any trouble.

2. Description of the Related Art Generally, a composition which exhibits functions such as curing and adhesion when mixed and has poor storage stability in the state of the composition is divided into a plurality of liquid components. Means are used for storage and mixing of these components at the time of use.

For example, a method of dividing dental cement into powder and a hardening liquid, storing them, and mixing them on a kneading paper at the time of use has been adopted.

However, in recent years, in order to simplify the kneading with the above-mentioned kneaded paper, the powder component is made into a paste with an inert liquid, and the paste and the hardening liquid component are divided and stored in a container, and the paste is made at the time of use. A method of mixing a powder component and a hardening liquid component has been proposed. That is, it is a method in which a liquid supply pipe is connected to each container in which each liquid component is present, and the liquid component is supplied to and mixed with a tubular mixer having a screw through the liquid supply pipe.

[0005]

However, in the above method, when the required amount of the composition is taken out from the mixer,
The liquid component or the mixture remains in the liquid supply pipe and the mixer, causing various problems. For example, the above dental cement has a problem that the composition is hardened in a mixer and cannot be used thereafter. Further, a mode in which the mixer part is replaced every time it is used is also proposed, but in such a mode, when handling a small amount of the mixture, the amount of the mixture remaining in the mixer is large, and the loss thereof is extremely large.

Means for Solving the Problems The inventors of the present invention have conducted extensive studies to solve the above problems. As a result, by forming a non-bonding part between the polymerized sheets, a plurality of liquid storage parts are provided so that an amount of liquid components corresponding to the amount used at one time can be stored, and at the same time, these liquid storage parts can be stored. Forming a mixing part for statically mixing the liquid and a discharge port for taking out the mixture from the mixing part, arranging the plurality of liquid storage parts in parallel, and the liquid storage part, the liquid flow path, and the mixing part. By arranging the discharge section and the discharge port in series in series, the entire structure can be made flat, and the amount of the mixture remaining in the container can be obtained by simultaneously squeezing out the liquid component from the end of the liquid storage section. The present invention has been completed by finding that the amount can be remarkably reduced and the mixture can be easily taken out.

The present invention will be described below in detail with reference to the accompanying drawings, but the present invention is not limited to these accompanying drawings.

FIG. 1 is a perspective view showing a typical embodiment of the liquid mixing container of the present invention.

The multi-component liquid mixing container 1 of the present invention comprises a plurality of liquid storage parts 3 each having a non-bonded portion formed between the polymerized sheets 2, and a plurality of liquid storage parts 3 communicating with the liquid storage parts 3. It has a mixing part 5 for statically mixing liquids and an outlet 6, the plurality of liquid storage parts 3 are arranged in parallel, and the liquid storage part 3 and the mixing part 5 are arranged.
Are arranged in series.

In the present invention, at least one of the sheets is made of a flexible material so that the liquid in the liquid storage section 3 and the mixing section 5 formed between the polymerized sheets can be easily squeezed out. It is preferable to configure. Generally, a stable material for the liquid to be filled may be selected and used from polyolefin resins such as polyethylene and polypropylene, and thermoplastic resins such as polycarbonate, polyamide, polyvinyl chloride, and fluororesin. That is, when one of the sheets to be polymerized has the above-mentioned flexibility, the other may be hard. Further, the “sheet” does not have a strict meaning in terms of thickness, and includes a film, a plate-like material and the like as long as the above-mentioned required properties can be satisfied.

In the present invention, the capacity of the liquid storage unit 3 may be appropriately determined according to the number corresponding to the liquid component, the amount of the liquid component, and the like. Further, the liquid storage units are arranged in parallel so that the liquid filled therein can be simultaneously supplied to the mixing unit. In this case, since the liquid is supplied from the liquid storage unit 3 to the mixing unit 7 at a constant rate, it is preferable to form a band having a constant width as shown in FIG. In the above aspect, the mixing ratio of the liquid can be adjusted by changing the width of each liquid storage unit 3.

In the present invention, each liquid storage section 3 and mixing section 5
Communication with can be done directly, but in general,
It is performed by providing the liquid flow path 4.

The mixing section 5 has a structure in which the liquid is statically mixed by passing the liquid through a flat space formed by providing a non-bonding portion between the superposed sheets. There is no particular limitation. As a preferable example, as shown in FIG. 1, there is a structure in which enlarged portions and narrowed portions are alternately provided in the liquid flow direction. With regard to the width ratio, the size, etc. of the enlarged portion and the narrowed portion, an optimum value may be appropriately determined according to the amount of liquid to be mixed and the viscosity of the liquid. Also,
FIG. 5 shows another embodiment of the liquid mixing container of the present invention. That is, FIG. 5 shows another aspect of the liquid mixing container of the present invention in which the weir 15 is formed in a zigzag shape with the enlarged portion and the squeezing portion of the mixing portion 5 alternately leaving a gap and the squeezing tool 7.

The method for filling the liquid storage unit 3 of the liquid mixing container 1 of the present invention with the liquid is not particularly limited. Generally, a method of filling the liquid before joining the ends of the liquid storage unit 3 and then joining the ends is recommended. Further, at the time of filling the liquid, it is preferable to form a temporary fixing part in order to prevent the liquid from flowing out from the liquid storage part 3 to the mixing part 5 during storage. The form of forming the temporary fixing portion is not particularly limited. Generally, this is performed by temporarily fixing the communication part between the liquid storage part 3 and the mixing part 5, generally the liquid flow path 4. For example, it has durability against the pressure of the liquid during storage, and when the constant pressure is applied to the liquid storage portion, the liquid flow path 4 is blocked by a weak joint that is preferentially broken than other joint portions. Of joining the sheets so that the liquid flow path 4
It is preferable that the device be clamped by a clip or the like to be cut off.

Further, in the present invention, when the liquid is squeezed out immediately after filling the liquid storage unit, it is not particularly necessary to join and seal the ends of the liquid storage unit, and the liquid supply nozzle is used. After filling each liquid storage unit with a required amount of liquid, a squeezing tool, which will be described later, is attached to the end portion and moved toward the discharge port to take out the mixed liquid.

The method of mixing and removing the liquid components filled in the liquid storage part 3 of the liquid mixing container 1 of the present invention is not particularly limited, but the polymerized sheet is sandwiched between the liquid storage part 3 and the liquid flow. A method using a squeezing tool having a function of moving while squeezing the liquid in the passage 4 and the mixing section 5 is preferable. The structure of the diaphragm 7 is not particularly limited as long as it has the above-mentioned function. For example, it is preferable that the liquid mixing container has substantially the same thickness as the polymerized film and has a slit through which the liquid mixing container can pass, and a roll composed of a pair of rolls. FIG. 1 shows a mode in which a diaphragm 7 having a slit 8 is used. According to this aspect, the liquid is sequentially moved to the liquid mixing unit 5 and the discharge port 8 by sliding the squeezing tool 7 from the end of the liquid storage unit 4 toward the discharge port 6, and the mixed liquid is taken out. It is preferable that at least the surface layer portion of the squeezing tool 7 is made of a material having lubricity in order to smoothly slide. For example, a material such as fluororesin is suitable.

Although not shown in the figure, a mode in which the squeezing tool is constituted by a pair of rolls sandwiching the polymerized sheet is also suitably adopted.
