Description

  The present invention is a food, daily necessities, industrial articles, diagnostic agents, etc. that need to be kept fresh until use, those that need to prevent the product from deteriorating, or those that need to be kept at the start of the reaction, Disposables made of thermoplastic resin that can be used by mixing multiple fluid components and holding them in their containers until they are used for the purpose. It relates to mixing containers.

  In general, in use, a plurality of fluid components are mixed and used each time depending on the purpose. For example, in the food field, concentrated coffee and concentrated sugar water or liquid cream, etc., in daily goods, in the cosmetics field, epoxy adhesive main ingredients and curing agents, hair dyes, etc. In many cases, a plurality of liquid components and viscous fluids such as a diluent are mixed and used each time.

Reasons for this include loss of flavor due to pre-mixing of individual components, loss of freshness due to contact with air, oxidative degradation due to oxygen, moisture, etc. in the air, alteration of components, or each This is due to avoiding alteration due to the progress of the reaction, loss of freedom, and the like.
For this reason, these multiple components have conventionally been put in separate containers, each with a single component, and have been used after being opened and mixed according to the purpose each time they are used. For example, in the food field, each is put in a plastic container sealed with an easy peelable film, in the daily necessities, cosmetics field, each is used in a separate tube, a pressure container, a tube, etc. In industrial parts, they are put in cans, bottles, etc., and in diagnostics, etc., they are put separately in glass containers called ampoules, and they are used so that they do not mix up until use. .

  However, emptying each container, taking out and mixing these components each time is a cumbersome task. If direct takeout and mixing are not possible, a special spoon and mixing and stirring tool are required, and the components are taken out. When the other component or impurities are mixed, the component may be altered, deteriorated or reacted, and may not be used. In addition, the spoon and tools may be washed away and prepared for the next use. It is necessary to place it and it is extremely complicated. Furthermore, it has been pointed out that when a glass ampoule is used, there are many problems such as the glass being folded and used, and there is a risk of scratching the hand at the edge.

  Among these, in order to eliminate the complexity, one container is housed in the other container as in the adhesive container found in JP-A-10-157777 (see Patent Document 1), and the container space is made efficient. Or, as seen in Japanese Patent Application Laid-Open No. 07-291365 (see Patent Document 2) and Japanese Patent Application Laid-Open No. 08-11913 (see Patent Document 3), the cosmetic ingredients are put in separate pressure vessels and mixed at the time of extrusion, or , A disposable container in which a liquid and a diluent as shown in Japanese Patent Laid-Open No. 09-113421 (see Patent Document 4) are mixed by pushing a capillary tube into a vacuum container, and further, as in Japanese Patent Laid-Open No. 05-294350 (see Patent Document 5). A disposable container that breaks and mixes using a crest-shaped portion of a seal of a container containing a liquid component with a hand-gripping pressure has been proposed.

  However, these satisfy the functions of maintaining freshness, preventing deterioration of components, preventing alteration, suppressing reaction, etc., when using each component. Since each component after the operation is expected to be free diffusion, simultaneous release mixing by internal pressure, and simultaneous suction mixing by decompression, the uniformity is positively increased. It didn't happen before. In addition, there is a problem of overuse, overuse, etc., because it is not the minimum unit of a certain amount required every time it is used, and some are only considering the container space and convenience of handling. There wasn't. For this reason, these problems are eliminated, and each unit is subdivided into use units each time to eliminate complications, and multiple components are easily mixed at the same time by human power to demonstrate the original intended function. There was a need for a disposable mixing container that could be discarded.

  The present invention is a disposable mixing container made of a thermoplastic resin, holding a plurality of fluid components in individual storage parts, and by applying human power during use, a part of the partition walls of each storage part It must be destroyed, mixed together and discharged.

  The container used in the present invention is made of a thermoplastic resin. Examples of the thermoplastic resin used here include general-purpose polystyrene, ABS resin, AS resin, impact-resistant polystyrene, MS resin, and other styrenic resins, vinyl chloride resin, polyethylene-based polyolefin-based resins such as polypropylene, and the like. General-purpose resin, engineering resin such as polymethyl methacrylate (PMMA), polycarbonate (PC), nylon (PA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyimide (PI), polyethersulfone ( Naturally composed of super engineering resins such as PES) and polyether ether ketone (PEEK), or synthetic biodegradable resins such as polylactic acid, polycaprolactone, and polybutylene succinate, cellulose acetate, chitosan, etc. Included are all biodegradable resins derived from styrene elastomers, polyolefin elastomers, nylon elastomers, etc. that can be plasticized by heating, injection molding, blow molding, or extrusion molding. . In addition, a mixture of these resins with various additives, colorants, fillers, a so-called polymer alloy in which the resins are mixed together can be used. It is possible to make several types of resin and combine them together.

In the disposable mixing container of the present invention, it is a requirement to hold a plurality of fluid components in individual storage units. Here, the fluid component that can be held in an individual storage unit is a fluid component that has a deformable liquid, viscous, and viscoelasticity by applying human power at room temperature, and the viscosity at room temperature is 0.2. It refers to the 10 ⁵ centipoise (C.P.). Specifically, so-called Newtonian fluids, solid particulates, which are aqueous solutions of organic solvents such as low-viscosity ethyl alcohol, acetone and methyl ethyl ketone, high-concentration liquid detergents, culture solutions containing enzyme components, and various diagnostic chemicals Pseudoplastic fluids, such as Bingham plastic fluids such as cosmetic liquids containing slurry clay components, high-concentration detergents including milk, cream, paints, gels, etc., high viscosity, viscoelasticity These include so-called non-Newtonian fluids such as high-concentration sugar water, starch syrup, honey, uncured epoxy resin main component, unsaturated polyester resin, and other dilatants, which exhibit fluidity at room temperature.

It can also be made into a desired shape by injection molding, blow molding, or extrusion molding, or can be made into a container by forming into a sheet or film by extrusion molding, vacuum forming, press forming, or heat sealing. Yes. The size and shape of the storage part are not particularly limited depending on the purpose, but when applying human power during use, the part of the partition wall is connected to the outer periphery so that part of the partition wall leading to the mixing part is destroyed. The thickness of the partition wall portion is about 0.01 to 1.0 mm, or a radial groove shape is applied to the partition wall in advance so as to promote breakage due to stress. Specifically, it is recommended that the partition wall is about 0.05 to 1.0 mm, a groove is provided radially from the center, and the thickness of the groove is 1/2 to 1/4 or less of the partition wall. Is done. In addition, a method including a mechanism for piercing with a needle-shaped or acute-angle resin molded product is also recommended so that the partition wall can be surely broken when human power is applied. In addition, in some cases, when the partition wall of the main storage unit leading to the mixing unit is manually applied, a special material such as a metal foil or thin film glass is more easily broken so that only the partition wall portion is destroyed. It is also possible to configure with. The individual storage portion of the present invention is made of a thermoplastic resin, but according to the properties of the flowable component of the contents, confidentiality, gas barrier property, ultraviolet resistance, etc. It is also possible to laminate with a metal foil or an extremely thin gas barrier film.

The present invention is characterized in that a part of the partition wall leading to the mixing part of the individual storage container containing a plurality of fluid components is destroyed by applying human power. Not only the form flowing into the mixing part, but depending on the case, it is also possible to connect individual storage containers continuously, sequentially break the partition walls, send the components, and finally introduce into the mixing part. .
The number of the individual storage units for storing the fluid component of the present invention is not particularly specified, but since it is a combination of components that are mixed and exhibit functions when used, it is necessary to provide at least two components or more. It is.

In the present invention, by using human power at the time of use, a part of the partition wall of each storage unit is destroyed, and the fluid component of the storage content is pushed out and flows into the mixing unit. Here, adding human power means actions such as pinching, twisting, twisting, turning, squeezing, pushing, crushing, stepping on, etc., and generally the contents of the mixed ingredients are small amounts of 5-10 cm ³ or less For objects, it is recommended to take a step such as stepping with a foot when the finger and hand strength is 2000 cm ³ or less. The transmission of the force to breakage of the storage partition wall by applying human power can be performed through a fluid component or directly in a shape obtained by processing a resin.

  As a mechanism that sends each fluid component from the storage unit to the mixing unit by applying human power, not only direct human actions but also those applied through various mechanism parts triggered by human action included. For example, in addition to a combination of a plate spring mechanism, a spring spring mechanism, a bending hinge mechanism, etc. that utilizes the elasticity of the thermoplastic resin used in the present invention at room temperature, as a normal molded product, a screw-type mechanism, a plunger type (Piston type) mechanism, narrowing type mechanism, etc. can be combined. Similarly, the mechanical part of the present invention can also be easily made by injection molding, blow molding, extrusion molding, or processing using a thermoplastic resin. Therefore, it can be set as a disposable mixing container by integrating with these.

  In the present invention, it is essential that a plurality of fluid components extruded by applying human power are introduced into the mixing section so as to be integrated, and after passing through the mixing section, are discharged from the discharge port. Here, the mixing part is easily made by processing a thermoplastic resin after injection molding or extrusion molding. The mixing unit of the present invention is a mechanism unit for introducing a plurality of fluid components and mixing them uniformly when passing, and specifically, a cylindrical tube or a conical tube whose diameter narrows toward the discharge port.
