Description

Ice pack for easy reuse and detachment {ICE PACK FOR EASY REUSE AND DETACHMENT}

The present invention relates to an ice pack that is easy to reuse and detach. In more detail, it is easy to replace the cover of the ice pack with a dual cover configuration of the first cover and the second cover, and the first cover is coated with an antibacterial and deodorant composition including rush extract, gentian extract and infant extract, antibacterial and It has excellent deodorizing effect, and relates to an ice pack that enables reuse.

With the recent development of the transportation industry, it has become possible to transport food products that require fast delivery from existing cargoes that do not have a shelf life. Since foods quickly decay when exposed to room temperature, they must be kept at low temperatures to maintain freshness.

Therefore, when transporting food, a separate means capable of freezing and refrigerating storage in the transport means is required. However, when transporting a small amount of food individually, rather than transporting a large amount of food ingredients or frozen foods, dry ice or ice packs are placed in the box containing the food to prevent spoilage.

Dry ice refers to a coolant made from solid carbon dioxide by compressing gaseous carbon dioxide. This dry ice cannot be easily obtained because it requires a separate manufacturing process. When the temperature is -78°C and touched with bare hands, frostbite It can be worn, so care should be taken in handling and storage. In addition, it is a one-time coolant that sublimates and disappears unless it is stored below -78℃, so its efficiency is low.

On the other hand, the ice pack contains a refrigerant with high specific heat inside, and by mixing the refrigerant with water and then freezing it, it is possible to keep the surroundings at a low temperature through the endothermic action of the ice pack. These ice packs are widely used because they are easy to handle and store, unlike dry ice, and can be used semi-permanently.

However, when the ice pack is discarded, if ammonium nitrate or ammonium chloride is a refrigerant, the ammonium nitrate and ammonium chloride are harmful substances, so disposal is not easy, and a super absorbent polymer made of eco-friendly materials (super If absorbent polymer) is used as a refrigerant, it is disposed of in a way that the user spills it into the sewer pipe because it maintains the gel form combined with water, but this has the side effect of clogging the sewer pipe.

Due to the above problems, the contents of the ice pack to be disposed of in general garbage are written on the case of the ice pack, but users do not recognize this and the case is made of a vinyl material, so users often collect and dispose of the refrigerant and case separately. In addition, even if the ice pack is disposed of as general garbage, a separate disposal treatment is required, so there is a problem in that it is cumbersome to discard the ice pack.

Therefore, it is possible to replace the separated material such as the ice pack case, excluding the semi-permanent refrigerant, so that when the user wants to dispose of the ice pack due to contamination or damage, it is easy to dispose of the separated material such as the ice pack case, excluding the refrigerant. There is a need for an ice pack to do it.

In addition, ice packs are mainly used to store concentrated, aquatic products and various foods at low temperatures so that they do not deteriorate. Most of them are packed by putting food in a styrofoam box and putting ice packs together. Therefore, the surface of the ice pack is easily moisturized, and in this case, an environment in which bacteria are suitable for propagation is applied. Since this acts as a cause of shortening the storage period of food, an additional function of antibacterial effect to prevent contamination in addition to the freezing and refrigerating functions of the ice pack is required.

1 is a cross-sectional view of an ice pack according to the present invention, and FIG. 2 is a view showing an attachment portion of another ice pack cover according to the present invention.

In the present invention, the ice pack includes a refrigerant (1), a first cover (10) having an accommodation space (11) capable of accommodating the refrigerant, a second cover (20) formed on the front and rear surfaces of the first cover, It refers to the attachment of the second cover through the attachment portion 12 formed on the edge of the first cover and the attachment portion 12.

In the present invention, the first cover 10 is a form that forms an accommodation space that can accommodate the refrigerant 1, and the material of the first cover 10 is polyethylene (PE), polyethylene terephthalate (PET), and stretched poly Propylene (OPP), nylon (NY), non-woven material or foam paper, styrofoam, may be made of a film laminated with insulation such as paper, but is not limited thereto, and the size and shape are not limited, It is defined as including the range that can be used by those of ordinary skill in the relevant field.

In the present invention, the second cover 20 is formed on the front and rear surfaces of the first cover 10 and attached through the attachment part 12, preferably polyester extracted from a PET (polyethylene terephthalate) bottle ( Polyester) fiber is used and can be recycled, but it is laminated with insulation materials such as polyethylene (PE), polyethylene terephthalate (PET), stretched polypropylene (OPP), nylon (NY), non-woven fabric or foam paper, styrofoam, and laminated paper. It may be made of a film or the like, but is not necessarily limited thereto. In addition, the size and shape are not limited, and it is defined as including a range that can be used by those of ordinary skill in the relevant field.

The polyethylene (PE) material is a heat-resistant material and is widely used in kitchenware, is easy to process, and is used in a variety of product lines, and is also a major raw material for PET bottles. In addition, discoloration hardly occurs even when exposed to sunlight for a long time, and it is a relatively safe material and is widely used in children's toys.

In addition, polyethylene (PE, Polyethylene) materials can be divided into high-density, low-density, medium-density, ultra-high-density, and ultra-low-density, depending on their density. The low-density polyethylene film layer (LDPE) is manufactured by polymerizing ethylene. As a synthetic resin, it is a transparent solid (density of 0.91~0.94) at room temperature and has low crystallization, so it has excellent processability, flexibility, and transparency, so it is used as a raw material for agricultural and packaging transparent films, wire coverings, and various wraps.

Nylon (NY) is a generic term for a linear synthetic polyamide among polyamides (polymer compounds having an amide bond -CONH), and ordinary nylon is roughly divided into two types. m, n-nylon or nylon mn is a polycondensate of a diamine NH2(CH2)mNH2 having m carbon atoms and a dibasic acid HOOC(CH2)n-2COOH having n carbon atoms, and industrially, 6, 6-nylon, 6, 10- Nylon, etc. are being produced. n-nylon or nylon n is a polycondensate or polymer of ω-amino acid H2N(CH2)nCOOH or lactam having n carbon atoms, and 6-nylon, 11-nylon, etc. are industrially produced. In addition, so-called hybrid polymerized nylon such as a hybrid condensation product of caprolactam and 6, 10-nylon salts (hexamethylenediamine and sebacate) is industrially produced.

Nylon (NY) generally has excellent impact resistance, mechanical properties such as tensile strength, yield point, and hardness are greatly influenced by the degree of crystallinity, and the degree of crystallinity varies depending on the molding method, molding conditions, and heat treatment. Nylon is insoluble in ordinary organic solvents and has strong resistance to alkali, but it dissolves in strong acids and hydrolyzes. As the solvent, phenols such as phenol and m-cresol, formic acid, and the like are used. Since nylon is weakened by ultraviolet rays, a product containing an ultraviolet absorber is used for outdoor use.

Non-woven fabric is made into a felt shape by arranging fibers in a parallel or negative direction without going through a weaving process and bonding them with a synthetic resin adhesive. Initially, cotton and viscose rayon were mainly used, but recently nylon, etc. Synthetic fibers are also used.

The attachment portion 12 is attached to the edge portions of the first cover and the second cover through heat seal.

The first cover and the second cover are bonded to each other along the attachment portion 12, and at the same time, the ice pack is formed as a double cover.

In the present invention, the attachment part 12 refers to the edge region of the first cover and the second cover. In this case, the bonding method may preferably be thermal bonding, but the bonding method is not limited, and the bonding method is sealed by high-frequency bonding. Any of the method, the method of bonding using a double-sided tape, and the bonding method using heat may be used, and it is defined as including a range that can be used by those of ordinary skill in the relevant field.

Heat seal is also called heat sealing or bonding sealing in other words, and is a method of bonding the same or different types of films or sheets using the heat melting property of the material. Polyethylene bags, which are commonly found in the surroundings, are also bonded using this method. Although the heat-bonded part is not separated by external force, the bonded part can be easily separated by human force. Therefore, in the present invention, the first cover 10 and the second cover 20 are bonded through thermal bonding for easy attachment and detachment.

Therefore, through the attachment portion 12, the second cover 20 has a built-in first cover for accommodating the refrigerant normally, and the second cover 20 can be pulled outwardly by an attractive force rather than an external force. Since the adhered inner surface of the part 12 is separated, the first cover and the second cover can be easily isolated.

The refrigerant is selected from the group consisting of super absorbent polymer.

Super absorbent polymer is a resin that can absorb water up to several tens to hundreds of times its own weight, and the super absorbent polymer powder that absorbs water changes to a gel form, and is used to freeze the super absorbent polymer changed to a gel form. As moisture in the water absorbent resin is liquefied, it absorbs heat from the surroundings, thereby reducing the ambient temperature.

The superabsorbent resin is a graft hybrid polymerization of acrylonitrile to starch or cellulose made from corn or potato starch, and makes it possible to use an environmentally friendly refrigerant that is harmless to the human body. In addition, disposal is easy because it can be disposed of as general waste and can be disposed of directly in the soil.

The second cover is recyclable with polyester fibers extracted from a PET (polyethylene terephthalate) bottle.

PET bottles are made of polyethylene terephthalate. They are light, unbreakable, and transparent, and are considered safe for food hygiene, so production is increasing, and they are widely used as containers for soft drinks or soy sauce and other seasonings. In this way, when recycling PET bottles that are widely used in the market, there is an advantage in that the separate collection after use of the ice pack is convenient and recycling is easy, compared to the ice pack, which costs a lot at the time of disposal.

In addition, since polyester foam is made of 100% recycled PET, it can be recycled immediately like an outer case, making it easy for anyone to use and discard.

The first cover is coated with an antibacterial and deodorizing composition.

The antibacterial and deodorizing composition in the present invention is to allow physical or chemical adsorption of a specific component, and the antibacterial and deodorizing composition may exert an antibacterial effect by adsorbing odors and other harmful bacteria.

The antibacterial and deodorizing compositions include fine powder shungite, fine powder illite, fine powder zeolite, fine powder elvan stone, fine powder bentonite, fine powder diatomaceous earth, fine powder germanium, fine powder loess, fine powder alum, fine powder jade ) And an inorganic powder selected from the group consisting of mixtures thereof.

The fine powder referred to in the present invention refers to crushing by a ball mill, jet mill, or other pulverizing device, or manufacturing to have the properties of a fine powder during the synthesis process, and the fine powder is defined as having an average particle diameter of 100 μm or less.

The šœgait in the present invention is calculated as a layer (up to 2 m thick) or a lenticular body among shales with a low degree of metamorphism rich in small graphite microcrystals from the Jatulian era in Shunga near the northern part of the Karelia Ladoga in Russia. . It is black like pitch, dense, opaque, metallic luster. It is soft. Hardness 2.5. d 1.75~1.80, making graphite acid from concentrated nitric acid without melting in a fire zone.

The chemical composition of ilite in the present invention is (K,H ₃ O)Al ₂ (Si,Al) ₄ O ₁₀ (H ₂ O,OH) ₂ . In terms of chemical composition, some are close to muscovite mica, but relatively SiO ₂ , MgO, H ₂ O are high and K ₂ O is low. It is a mineral of the same family as hundreds of mica. Hardness 1 to 2, specific gravity 2.6 to 2.9. The cleavage is complete, and the streak color is white, and there is a earthy gloss. There is a view that it is not an independent mineral in terms of its chemical composition or crystal structure, but a mixed mineral containing other components. It is produced in aluminum-rich heterogeneous or tuff-like sedimentary rocks, and is produced as a metamorphic mineral of a hydrothermal mineral bedrock.

Zeolite referred to in the present invention is also referred to as a tombstone (沸石). There are many types, but they have a lot of water content, properties of crystals, and the like. Hardness does not exceed 6, and specific gravity is about 2.2. It is generally colorless, transparent or white translucent. When heated with a blowpipe, it boils and becomes bulging, so it got this name. Most types dissolve in hydrochloric acid and are often glued, but few types do not dissolve in hydrochloric acid. As the main types, there are Bangbistone, Fisheye Stone, Chabazite, Soda Stone, Heullandite, Steelbite, Lomontite, and Innessite. It is produced from voids or fissures of basic igneous rocks such as basalt or tuff, and sometimes exists as a secondary mineral among granite and gneiss. It may also be produced in gold veins or other veins. In the crystal structure, the bonds of each atom are loose, and even if the moisture filling between them is released by high heat, the skeleton remains intact, so other particulate matter can be adsorbed. Using this property, it is used as an adsorbent, and it is used as a molecular sieve that separates fine particles of different sizes.

Elvan stone referred to in the present invention is known as a term used in Chinese herbal medicine, and it belongs to granite class geologically. It is the same as quartz porphyry, feldspar porphyry, and granite porphyry, and the name of the rock coincides with quartz-monzonite. Quartz and feldspar are densely mixed. Yellowish white, light yellowish brown, light gray, dark green or light green rocks with red dots or white dots evenly mixed together are like rice balls made of barley, so the name Elvan Stone was given. The main components are silicic anhydride and aluminum oxide, and it contains a small amount of iron oxide. Known as the yellowish white elvan stone, it was previously used as an anti-inflammatory agent to treat skin diseases such as swelling or boils on the back and a filter to purify pills. According to Donguibogam, its nature is sweet, warm, and non-poisonous. It is made up of 30,000 to 150,000 holes per 1 cm ^3, so it has strong adsorption and contains about 25,000 kinds of inorganic salts. It is also used as a harmful metal removal agent because it exchanges ions with heavy metals, and it is known to emit far-infrared rays when heat is applied to this rock. Because of this characteristic, it is used in various industrial sectors such as jjimjilbang, tableware, and medical equipment.

Benzoite used in the present invention includes quartz, feldspar, zeolite, and the like. The color is white, gray, pale brown, pale green. It has pearl gloss, lead gloss, and is produced as a dense mass with a sense of fat, which is similar to the properties of montmorillonite, such as swelling by adsorbing water and having clear cation exchange properties. Tuff and vitreous rhyolite have been altered. Its use is very wide, and it is also used as the main component of Isu for petroleum refinery, as a binder for castings, as a mixing agent for raw materials for ceramics, and as a base for ointments. The name comes from the strata of Wyoming, the United States, where it was discovered.

Diatomaceous earth referred to in the present invention is mainly made of silicic acid (SiO2), and has a white or grayish white color. It is light and soft enough to smear powder when touched with your fingers. Because it is a fine porous material, it has strong absorbency and is a poor conductor of heat. Diatomaceous earth in our country is calculated as soil within the tertiary or fourth stratum. During the third period of the ancient period of our country, fault movements in the northeast to northeast directions occurred, forming sedimentary basins in several places. The Yeongil Basin, the Earth Zone between Gilju and Myeongcheon, the Earth Zone between Seoul and Wonsan, and the Tuman River Basin were formed, and the third base was deposited there. When sedimentary layers were formed, diatoms were deposited in small shallow lakes or freshwater basins in various places to form deposits. Among these sedimentary basins, diatomaceous earth in Yeongil Bay is the largest in diatomite deposits, and is found intensively in Wolseong and Yeongil, Gyeongsangbuk-do. In addition, in North Korea, Haenghyeon-ri, Munsan-myeon, Anbyeon-gun, Anbyeon-gun, Namsan-ri, Anbyeon-myeon, Anbyeon-gun, Hamgyeongbuk-do, Bupyeong-dong, Junam-myeon, Gyeongseong-gun, Hoemun mine, Ungpyeong-myeon, Gilju-gun, Sanbon mine, Myeongcheon-gun, Myeongcheon-gun Seomyeon, Baekrok mine, Gangwon-do The production centers of Sephori, Gosaph-myeon, Pyeonggang-gun, etc. are known. The development of diatomaceous earth as a deposit in Korea began in 1941, when it was incorporated as a designated legal mineral under the'Chosun Mining Ordinance' (朝鮮鑛業令). Since then, domestic diatomite deposits have been discovered in various places, and in particular, diatomaceous earth produced in Iil-ri, Yangbuk-myeon, Wolseong-gun, Gyeongsangbuk-do, is said to have been used as a raw material for the manufacture of Asahi furnaces in Japan at Nodong-ri, Gyeongju. In recent years, it is used as a refractory material, and because of its strong absorption, it is mostly used as a filter material for purification of industrial water, water, medicine, and food. In addition, it is used as a filler for plastics and paper, adsorbent for dynamite, hemostatic agent, and a mixture of cement.

Germanium in the present invention has an element symbol Ge, an atomic number of 32, and an atomic weight of 72.59±3. Its existence was predicted by D. I. Mendeleev in 1871, and it was called Ekasil. However, it was discovered in Ag GeS by German chemist C. A. Binkler in 86 and named after the German Latin name ``Germania''. Since it is similar to silicon, it is widely present by substituting with silicon in the silicate in the crust. Also, it is contained in sulfide minerals or coals containing copper or zinc, but there are very few minerals based on germanium.

The alum stone referred to in the present invention is also referred to as alum stone. The chemical composition is KAl ₃ (SO ₄ ) ₂ (OH) ₆ . It appears as a hexagonal plate-like or impression-shaped crystal, usually in the form of a mass or granular shape (粒狀). Hardness 3.5 to 4, specific gravity 2.6 to 2.9. Crystalline ones have a complete split on the bottom and a pearly luster on the split side. The odd one is not glossy. It is white, gray and sometimes red, yellow, or reddish brown. Streak color (條痕色) is white. Insoluble in hydrochloric acid, soluble in potassium hydroxide or hot sulfuric acid. It is produced in the volcanic rock area that has undergone a change of hydrothermal water.

The term jade in the present invention refers to dense, hard, transparent, beautifully shiny, polished and glossy. Mineralogically, purgatory is a type of amphibole, and jadeite is a type of alkali pyrite. Purgatory is often milky white, and there are also green, yellow, and red, and jadeite is green and white. There are various names depending on the color, but white jade and jade are typical. It has been prized in the East since ancient times, and has been handcrafted and used as a decorative stone and jadeite. Purgatory is produced as veins in crystalline schist or gneiss in Turkey and elsewhere, and in the contact zone of granite in northeast China. Jadeite is produced by forming veins among serpentine in Myanmar, and is also produced in Yunnan, China and Tibetan Plateau. Although jade in the narrow sense refers to jade, the present invention is not limited thereto, and jade in the present invention is defined as including all of the jade in the broad sense described above.
