Description

  Functional Plastic Container {Functionality Plastic Container}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin container. Specifically, in the production of a synthetic resin container for storing food, beverages, alcoholic beverages, and the like, the container is prepared by adding ultra-fine particles composed of nanometer-sized particles as a natural substance to the synthetic resin, which is a material for manufacturing the container. By maintaining the properties of the conventional plastic container as it is, while maintaining the properties of the far-infrared or negative ions in the plastic container at the same time, having a breathable, the material to be stored, such as antibacterial, deodorizing, fermentation, ripening effect is generated A functional plastic container that can be.

Synthetic resin containers, such as plastics, formed of synthetic resins as main materials, are widely used as containers for storing various types of liquids or solids because of easy storage of materials, easy handling, and low-cost mass production.

Among the plastic containers, the most commonly used plastic bottle is polyethylene terephthalate (PET) as the main raw material. However, the plastic bottle is known to dissolve the antimony trioxide in the material produced, and long-term exposure to the antimony trioxide can cause respiratory diseases, dermatitis, and the like. Therefore, the longer the food is put in a plastic container such as plastic bottles, the more likely the food is deteriorated into a harmful state.

In particular, containers formed of synthetic resins are known to store very small amounts of dioxin, a factor that causes cancer in the human body when high heat or salty foods are stored.

Accordingly, a resin container has been formed by using additives of various components as a means for preventing harmful components generated in the resin container. Among them, Korean Patent No. 152315 proposes a method for producing an antimicrobial synthetic resin containing one component of silver, copper, tin, and arsenic ions, and adding an inorganic ceramic metal ion carrier containing zirconium and sodium as a main component to the synthetic resin. In Korean Patent No. 668486, a carrier consisting of titanium dioxide and zinc oxide and a functional master batch including silver and magnesium oxide supported on the carrier have been proposed.

However, these materials are troublesome in the process of refining and manufacturing the inorganic and metal ions, color reaction or discoloration due to the reactivity of the metal salt, and there is a problem that there is a risk of decomposition at high temperature due to low thermal stability.

In addition, synthetic resin containers made of plastic are not able to realize breathing functions such as earthenware or jars because the body of the container is completely blocked from the outside and breathability is not secured at all, thereby aging or fermenting the food contained therein. It's also impossible to save it. Accordingly, in order to smoothly ripen or ferment food, it is necessary to use a bulky, heavy and fragile jar or earthenware until now.

In addition, the conventional plastic container has no function to deodorize different odors or prevent the growth of bacteria that are harmful to the human body depending on the type of material stored therein, so that the material stored in the plastic container can be safely and long-term stored. There is no problem.

The problem to be solved by the present invention is to solve the above problems, in forming a synthetic resin container, made of a natural material, by forming a container by adding a very small particles having a nanometer size to the synthetic resin, the conventional synthetic resin While the storage and management function of the material of the container remains intact, the body of the synthetic resin container is provided with air permeability to ripen or ferment the material stored as a jar, and at the same time suppress the harmful elements to the human body generated from the resin. And, to provide a functional synthetic resin container having a function to achieve the antibacterial or deodorant effect on the material to be stored.

In order to solve the above problems, the present invention in the production of a container formed of a synthetic resin, a natural material consisting of micronized tourmaline, willow charcoal, germanium, elvan, kaolin and anionite in a nanometer size to the base synthetic resin The material additive is added to form the synthetic resin chip 1, and then melted to inject a container 2 having a predetermined shape into the container mold for injection molding.

The synthetic resin that is the base of the synthetic resin chip may select any one of polyethylene, polypropylene, polyethylene terephthalate (PET), polycarbonate, nylon, polyurethane, polystyrene, acrylic, and copolymers thereof.

The weight ratio constituting the synthetic resin chip is a synthetic resin that is selected as one of the materials to include 63% by weight to 93.5% by weight of the total weight, here is 1 ~ 3% by weight of tourmaline natural additives, charcoal 1 ~ 5% by weight, germanium 0.5 ~ 5% by weight, ganban stone 1.5 ~ 7% by weight, kaolin 1.5 ~ 7% by weight, anionic stone 1 to 10% by weight in a molten state, the natural additives of 1nm to 10nm size Use what is formed of very fine particles.

The tourmaline is for generating far-infrared rays in the synthetic resin, usually called tourmaline, and is used as a gem as a hexagonal crystal system having a hardness of 7.25 and a specific gravity of 3.05, of which opaque tourmaline is to be used. The tourmaline is a polar crystal and permanently flows a microcurrent of 0.06, and has a piezoelectric property to prevent static electricity. Therefore, 1 to 3% by weight of the total synthetic resin chip is added.

The charcoal is preferably used to form willow charcoal charcoal and refined. The willow charcoal has excellent deodorization due to the antimicrobial properties and porosity of the charcoal, so that 1 ~ 5% of the total charcoal chip charcoal is added.

The germanium has a functional effect of generating a synergistic effect of far-infrared radiation and anion generation due to the semiconductor properties, so that 0.5 to 5% of the total weight of the synthetic resin chip is added.

The elvan is adsorbed by the silicon monoxide radicals in the elvan, and adsorbs the surrounding odor particles, which is excellent in antibacterial and deodorizing properties, and is advantageous for securing the insulation and insulation of the container by maintaining air and moisture in the fine pores. Add 1.5 to 7% of the resin chip weight.

The kaolin is mainly composed of kaolinite Al2O3 · 2SiO2 · 2H2O and halosite Al2O3 · SiO2 · 4H2O, and turns into lusite (K2O · Al2O3 · 4SiO2) at 800 ° C or higher, and the micropores pass through the air but The silver is small enough not to pass through and acts like a sponge and prevents corruption of the contents by allowing air to circulate in and out of the functional resin bottle. In addition, it has a porous structure that can adsorb functional mixtures for a long time, and serves to enhance the sustainability of far-infrared radiation in addition to the effect of kaolin itself, so that 1.5 to 7% of the total weight of the resin chip is added.

Since the anion stone is known to have a function of preventing electromagnetic waves by generating a weak current of 0.06 mA simultaneously with far-infrared radiation and anion generation, it is to be added to 1 ~ 10% of the total weight of the synthetic resin chip.

As described above, the additive of nano-scale natural substance is added to the synthetic resin in a molten state and injection-molded into a chip shape of a certain size, and the synthetic resin chip is dissolved again and injected into a mold having a container shape to form a functional synthetic resin container. To form.

As described above, by adding a natural substance additive to the synthetic resin to form a functional synthetic resin container, according to each characteristic of the added substance, it is possible to convert the contents contained in the container into beneficial ones by radiating far infrared rays and anions in the container itself. Of course, the effect of implementing the antibacterial, deodorant function of the contents stored in the container.

In addition, the functional synthetic resin container of the present invention is breathable due to the natural additives to provide a breath-like function, such as a jar, ripening or fermentation may be progressed while storing or storing foods such as kimchi, soy sauce, etc. The effect is to produce.

In particular, liquor, such as fresh makgeolli, can be achieved when fermentation is completed, and the original taste of the raw makgeolli is achieved.In order to store it so that it can be ingested after fermentation is completed, it cannot be stored for more than 20 days even if the storage conditions are good. short. However, when stored in a container made of the functional synthetic resin of the present invention, there is an effect that can delay the period of change by the far infrared and anion generated in the container.

In addition, since the functional synthetic resin has the same breathability as a jar, it is possible to proceed with the fermentation even when the raw rice wine is stored in the container, bottling the rice wine of the fermentation is not complete, and the bottle of makgeolli in the distribution process Fermentation and ripening can proceed so that the effect of extending the shelf life will occur.

Detailed description for carrying out the present invention will be described with reference to the accompanying drawings.

The present invention, in the production of a container formed of a synthetic resin, by adding an additive made of a natural material to the base synthetic resin to form a synthetic resin chip (1), by melting it to form a functional synthetic resin container (2) To form.

       More specifically, as shown in Figure 1, the additive made of a natural material included in the synthetic resin chip 1 is processed into a microparticles corresponding to nanometer size of tourmaline, charcoal, germanium, elvan, kaolin and anion stone Form. Then, by adding these natural substance additives to the synthetic resin in a molten state, the synthetic resin chip 1 having a predetermined shape is injection molded, and the synthetic resin chip 1 is melted and injected into a container-shaped mold, and the functional synthetic resin container as shown in FIG. (2) is formed.

Synthetic resin, which is the main material of the synthetic resin chip, is not limited in kind, but high density polyethylene (HDPE), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) can be used as the polyethylene resin, and also polypropylene and polyethylene terephthalate. (PET), polycarbonate, nylon, polyurethane, general polystyrene (GPPS), high strength polystyrene (HIPS), acrylonitrile butadiene styrene (ABS), styrene-acrylonitrile (SAN) and copolymers thereof Can be selected.

The synthetic resin chip 1 is formed of 63% by weight to 93.5% by weight of the total weight of the synthetic resin selected from any one material, including the polyethylene resin, the remaining weight is to be formed by adding the natural material additives. This is because when the synthetic resin is more than 93.5% by weight, the portion occupied by the natural substance additive decreases and its function is lowered. When the synthetic resin is less than 63% by weight, it is difficult to control the extrusion conditions of the resin composition.

The natural additives are formed to form microparticles having a size of 1 nm to 10 nm. The weight ratio added to the synthetic resin is 1 to 3% by weight of tourmaline, 1 to 5% by weight of charcoal, 0.5 to 5% by weight of germanium, 1.5 to 7% by weight of elvan, and kaolin based on the total weight of the resin chip (1). Is 1.5 to 7% by weight, anionic stone is to be included 1 to 10% by weight. Hereinafter will be described in detail with respect to the natural substance additive is added.

The tourmaline is for generating far-infrared rays in the synthetic resin, usually called tourmaline, and is used as a gem as a hexagonal crystal system having a hardness of 7.25 and a specific gravity of 3.05, of which opaque tourmaline is to be used. The tourmaline is a polar crystal and permanently flows a microcurrent of 0.06, and has a piezoelectric property to prevent static electricity. Therefore, 1 to 3% by weight of the total synthetic resin chip is added.

When the tourmaline is less than 1% by weight, it is difficult to sustain the expression of far infrared rays due to the weak electrical performance, and exceeds 3% by weight, there is no performance improvement effect as much as the waste of raw materials.

The germanium has a functional effect of generating a synergistic effect of far-infrared radiation and anion generation due to the semiconductor properties, so that 0.5 to 5% by weight of the total weight of the synthetic resin chip. When the germanium is less than 0.5% by weight, the far-infrared radiation effect is lowered, when the germanium is more than 5% by weight, there is no additional effect generated as much as excess, causing waste of raw materials.

The charcoal is preferably used to form willow charcoal charcoal and refined. Willow charcoal has excellent deodorization due to its antimicrobial and porosity, so that 1 ~ 5% by weight of charcoal of the total resin chip weight should be added.

The willow charcoal is added to the powder or colloidal state of 10 or less, if the willow charcoal is added less than 1% by weight deodorization rate of synthetic resin drops to less than 81% and higher than 5% by weight deodorization rate is high However, it is because molding of the plastic container becomes difficult.

The elvan is adsorbed by the silicon monoxide radicals in the elvan, and adsorbs the surrounding odor particles, which is excellent in antibacterial and adsorbability, and maintains air and moisture in the fine pores, which is advantageous for securing the insulation and insulation of the container. Add 1.5 to 7% by weight of the resin chip weight. If the elvan is less than 1.5% by weight, the antimicrobial and deodorizing effect of the elvan is insignificant, and if the elvan is more than 7% by weight, the compatibility with the resin is lowered and dispersion becomes difficult.

The kaolin is changed to rosite (K2O · Al2O3 · 4SiO2) at 800 ℃ or higher to form micropores, and these micropores are small enough to pass air but not to pass water, acting like a sponge, and air inside and outside the functional resin bottle. It prevents the decay of the contents by the circulation of, and also adsorbs the functional mixture for a long time to enhance the persistence of the far infrared radiation. The kaolin is to be added 1.5 to 7% by weight. When the kaolin is less than 1% by weight, the adsorption performance of the kaolin is not expressed, and when it is more than 7% by weight, the compatibility with the synthetic resin is reduced, the synthetic resin formation workability is lowered.

The anion stone has a function of preventing electromagnetic waves by generating a weak current of 0.06 mA simultaneously with far-infrared radiation and anion generation. When the anionic stone is less than 1% by weight, the effect is insignificant, and when it exceeds 10% by weight, it is preferable to add 1 to 10% by weight since the effect of the excess amount does not appear, resulting in waste of raw materials.

As described above, the function and action of the functional synthetic resin container (2) formed by adding ultrafine particles having a size of 1 nm to 10 nm with natural substance additives consisting of tourmaline, willow charcoal, germanium, elvan, kaolin and anionic stones to the synthetic resin are as follows. Is the same as

First, the far-infrared emission amount is measured according to the radiation energy measurement method (KICM-FIR-1005) prescribed by the Korea Institute of Construction Materials. And the radiant energy is 3.66 × 10 ² W / m ² .

In addition, the anion generation was measured using an ion counter of Alpha Lab, Inc. As a result, 1,500 to 2,000 were generated in 1 cm 3, and the antibacterial rate against various bacteria was determined by E. coli and yellow by the Japanese Industrial Standard JIS Z 2801 film adhesion method. As a result of testing the antimicrobial status by Staphylococcus aureus, it was confirmed that the antimicrobial activity of E. coli was 4.0 and the antibacterial effect was 99.99% or more. have.

In addition, as shown in Figure 3 when the deodorizing state tested in a state in which the functional synthetic resin container (2) formed by adding the willow charcoal and ganban stone exposed to ammonia gas, ammonia remains at 17 ppm after 30 minutes After 1 hour, it is reduced to about 10ppm, it can be seen that up to 90% deodorizing effect occurs over time.

In addition, the breathability of the functional synthetic resin container (2) was measured by a mercury porosimeter (Auto Pore IV9510, Micromeritics, Norcross, GA, USA) to confirm the microstructure of the material. In a conventional glazed jar, the pore diameter of 440 ~ 500nm, porosity of about 11 to 12% is measured, the functional synthetic resin container (2) of the present invention is a pore diameter of 400 ~ 500nm, porosity close to the jar measurement value Was measured at 5-8%, confirming close to the micropores and porosity of the jar.

In addition, the fermentation and aging of makgeolli was tested. As a result of measuring the state while storing the non-fermented makgeolli in a regular plastic bottle and the functional synthetic resin container of the present invention for a certain period of time under the same conditions, as shown in Figure 4, the makgeolli in the functional synthetic resin container of the present invention bottling After 4 days from 100% aging and the condition is continued, it was measured that the makgeolli in general plastic bottle is not matured more than 25% after 4 days or more.

As described above, by adding a natural substance additive to a synthetic resin to form a container, the contents of the container are converted into beneficial to the human body by radiating far infrared rays and anions in the container itself according to the characteristics of the added material. The antimicrobial and deodorant effects of the contents stored in the will occur.

In addition, the functional synthetic resin container of the present invention is secured breathability is provided with a breathing function, such as a jar, so that the effect of the fermentation and fermentation can proceed while storing or storing foods such as kimchi, soy sauce that needs aging or fermentation .

In particular, fermented foods such as makmakriri must be fermented to achieve the original taste of makmakriri, and after fermentation is completed, it can not be stored for more than 20 days even if the storage conditions are good to keep it from being deteriorated. This short, but stored in a container made of the functional synthetic resin of the present invention, there is an effect that can delay the period of change by the far infrared and anion generated in the container.

In addition, since the functional synthetic resin container has the same breathability as a jar, it is possible to proceed with the fermentation even when the raw rice wine is stored in the container, bottling the rice wine of the fermentation is not complete, and the rice wine bottled in the distribution process Fermentation and aging of the process can proceed so that the shelf life can be increased to effect the effect.
