Description

STORAGE BOX

The present invention relates to a storage container capable of storing a flower or food or the like for a long time.

In recent years, agricultural products such as flowers, fruits and vegetables produced at home and abroad are being sold to consumers through various routes due to development of the Internet and transportation means.

The agricultural product can be delivered directly from the producer to the consumer, and can be delivered to the consumer through a retail store such as a discount store.

In this case, if the product is delivered to a consumer through a retailer, it is difficult to keep the agricultural product in a refrigerated state, thereby deteriorating the quality of the agricultural product.

Accordingly, the method of maintaining the quality of the agricultural products during the distribution process is as important as the cultivation technology of the agricultural products.

For example, fruits are harvested and stored in a packing box in a large number, and they are circulated. As a result, friction occurs between the fruits during transportation, and not only the scars are easily scratched, but also the scratched parts are rapidly burned and the merchantability is lowered. In particular, in the case of fruits with flesh, if the air can not flow smoothly, the fruit will be broken down in a short time.

In this regard, Korean Unexamined Utility Model Publication No. 2010-0008433 discloses a method for preparing a fruit having an air passage formed with an air hole in a seating portion where fruits are seated.

The above-mentioned technology can prevent the decomposition of fruits by delaying the maturation of fruits by rapidly discharging the gas generated from the fruits through the air through holes. However, microorganisms flow into the air holes to promote the decay of the fruits, It may be difficult to maintain the freshness of the water. In addition, the freshness of the fruit may be changed according to the external environment conditions, and the use thereof is severely restricted.

The base layer 41 includes a polymer resin that absorbs or releases moisture depending on the temperature.

The polymer resin has the characteristics of water swelling and water insolubility. After absorbing water two to 100 times its own weight, the polymer resin shrinks by heating and releases moisture.

Such a polymer resin may be a polymer of a (meth) acrylamide derivative, an alkyl vinyl ether polymer, or a mixture of these polymers.

More specifically, the (meth) acrylamide derivatives may include N-propyl acrylamide, N-propyl (meth) acrylamide, N-isopropyl acrylamide, N-isopropyl (meth) Acrylamide, N, N-diethylacrylamide, N-ethyl (meth) acrylamide, N, N-dimethylacrylamide, N- acryloylpyrrolidine, N- (Meth) acryloylpiperidine, N- (meth) acryloylalanine, N-methylpyrrolidone, N- (meth) acryloylpiperidine and N- (meth) acryloylalanine.

Also, methyl vinyl ether can be used as the alkyl vinyl ether polymer.

The polymer resin may further include a copolymer selected from the group consisting of a hydrophilic monomer, a lipophilic monomer, and an ionic monomer in order to control the amount of water absorption or improve the shape.

Specific examples of the hydrophilic monomers include acrylamide, methacrylamide, N-methylacrylamide, diacetone acrylamide, hydroxyethyl (meth) acrylate, hydroxyethyl acrylate, hydroxypropyl (meth) acrylate, (Meth) acrylate, methoxypolyethylene glycol (meth) acrylate, methoxypolyethylene glycol acrylate, and N-vinyl-2-pyrrolidone.

In addition, a product obtained by copolymerizing vinyl acetate and glycidyl methacrylate and hydrolyzing it to give a hydrophilic property can be used.

Specific examples of the N-alkoxymethyl (meth) acrylamide derivative include N-hydroxymethyl (meth) acrylamide, N-methylol (meth) acrylamide, N-methoxymethyl Butoxymethyl (meth) acrylamide, and the like.

At this time, the water absorption or release temperature of the polymer resin can be controlled within the range of 10 to 100 ° C, and the temperature range can be controlled according to the selective use of the polymer resin. Preferably, the polymer resin is selected so as to emit moisture at a temperature above 50 ° C.

The shape of the polymer resin is not particularly limited, and examples thereof include a powder, a sheet, a fiber, a film, a gel, and the like. Preferably, the polymer resin is in contact with a material other than the absorbent polymer resin constituting the base layer 41 Considering compatibility, it is preferable to be in a powder form or a gel form.

The moisture contained in the storage container 10 can be kept constant by the substrate layer 41 made of the above-mentioned material to prevent the stored product from drying.

In addition, since the polymer resin constituting the lid 30 repeatedly absorbs or emits moisture, the lid 30 can be reused.

In addition to the above-mentioned polymeric resin, the base layer 41 may further include a photocatalyst and a transparent or opaque flexible material so as to facilitate fabrication and handling.

The photocatalyst is a material that absorbs light and promotes a chemical reaction. Examples of the material include titanium dioxide (TiO ₂ ), zinc oxide (ZnO), cadmium sulfide (CdS), and tungsten oxide (WO ₃ ) It is preferable to use nontoxic titanium dioxide (TiO ₂ ).

Such titanium dioxide can cause a chemical reaction by light having an ultraviolet wavelength region or a blue wavelength region of about 200 to 450 nm, thereby oxidizing and decomposing foreign substances.

As the flexible material, those known in the art may be used. For example, an epoxy resin, an acrylic resin, polyimide, polyethylene terephthalate (PET), polymethylmethacrylate (PMMA), polycarbonate (PC) Sulfone, polyethylene sulfone (PES) can be used.

On one side of the substrate layer 41, a heat generating optical layer 42 and a protective layer 45 are laminated on the heat generating optical layer 42.

The heat generating optical layer 42 includes an optical fiber 43 and a heat ray 44 and is attached to one surface of the base layer 41.

The optical fiber 43 is a fiber-shaped waveguide for transmitting light, and is also called an optical fiber. The optical fiber 43 is a fiber made by drawing a transparent dielectric such as quartz glass or plastic elongatedly, and the light passes through the center of the fiber and bends little by little so that the light is not leaked but propagated to a long distance.

Since the optical fiber 43 is slim and light, it is resistant to bending and strong against changes in the external environment and can be used as a lighting device in a food storage container since no heat is generated.

The optical fiber 43 is connected to an LED light source 51 formed on one side of the frame 50 and receives light generated from the LED light source 51 to irradiate light stored in the main body 20 with light .

The LED light source 51 is a light source having a high luminance and a long lifetime and includes an LED that emits light in a visible light region such as red, blue, green and white LED, light in an ultraviolet (UV) region, And may include a light source 51.

Specifically, the LED light source 51 has a visible light region in the range of 100 to 300 nm, 360 to 405 nm, 430 to 490 nm, 495 to 610 nm, 615 to 680 nm, an infrared region in the range of 760 to 1300 nm, And it is preferable to selectively use the wavelength of the appropriate region band depending on the kind of the storage and the storage purpose.

More preferably, the LED light source 51 is an ultraviolet LED light source that emits a wavelength in the range of 360 to 405 nm. When the ultraviolet ray irradiation area is within the above-described range, the LED light source 51 can inhibit the decay of foods, that is, fruits, vegetables, and the like, and delay the maturation thereof.

At this time, when the optical fiber 43 irradiates ultraviolet rays in the range of 365 to 405 nm, it is possible to prevent decay of stored products, that is, fruits or vegetables, and to delay maturation, so that the freshness of the food can be maintained while being kept for a long period of time.

The optical fiber 43 may be any of those known in the art, and may be, for example, a silicon oxide (SiO ₂ ) optical fiber.

The optical fibers 43 may be arranged in various forms on the base layer 41, and may be arranged in a row in the longitudinal direction or width direction of the base layer 41, for example.

At this time, the heat ray 44 may be arranged so as to be parallel to the optical fiber 43.

The heat ray 44 is formed to supply heat to the polymer resin so that the polymer resin discharges water. The heat ray 44 may be one that is well known in the art. For example, the heat ray 44 may be a nichrome ray generated by a resistor and may be covered with an insulating covering material.

Such a heat ray 44 has a disadvantage in that it can exert an effect only on a relatively small area as compared with a heating plate in the form of a plate, but in the lid 30 of the present invention, it is not necessary to generate heat at a high temperature.

A power supply unit 52 is formed on one side of the frame 50 to supply power to the optical fiber 43 and the heat ray 44.

The power supply 52 is for independently operating the LED light source 51 and the heat ray 44, and may further include an on-off switch.

The power supply unit 52 may further include a charging device when the battery pack is a rechargeable battery, and may further include a battery and an outlet when the battery pack is non-rechargeable.

A protective layer 45 is formed on the heat generating optical layer 42 to protect the optical fiber 43 and the heat ray 44.

For example, the protective layer 45 may be formed by applying a transparent polyether polyol, which is stable at room temperature and atmospheric pressure and easily absorbs external impact, on the heat generating light layer 42, have.

In the present invention, although not shown, a photocatalyst layer may be further formed on at least one side of the base layer 41 and the protective layer 45, and preferably a base layer (not shown) 41 and the protective layer 45 may be further formed.

Since the photocatalyst layer is the same as the photocatalyst included in the cover 30, detailed description thereof will be omitted.

However, the photocatalyst layer may be coated or sprayed in the form of a thin film on the surface of the base layer 41 and the protective layer 45, and the coating method is not particularly limited.

The lid 30 including the laminate 40 formed in this way is formed with a predetermined width at both ends of the other surface of the base layer 41 in order to cover the main body 20. [

The material of the pressure-sensitive adhesive applied to the bonding portion 46 is not particularly limited, and for example, a rubber, acrylic, or silicone pressure-sensitive adhesive may be used.

In the case where the adhesive portion 46 coated with the adhesive is formed, a release paper may be additionally formed to prevent the laminate 40 from being laminated or wound while being stored.

At this time, the release paper is formed to have the same width as that of the adhesive applied to the adhesive section 46, so that the release paper can be easily peeled off when the cover 30 is covered with the main body 20.

FIG. 4 is a view illustrating a state in which a main body and a cover are coupled according to an embodiment of the present invention, and FIG. 5 is a view illustrating a state in which a main body and a cover are coupled according to another embodiment of the present invention.

As shown in FIGS. 4 and 5, the storage container according to the present invention is covered with the cover 30 by covering the open top of the main body 20.

As shown in FIG. 4, the main body 20 is horizontally extended from the upper end of the main body 20 in the center direction so that a part of the opening is closed And the upper plate 23 is joined to the bonding portion 46 of the base layer 41 so that the body 20 and the lid 30 can be coupled to each other.

5, the lid 30 further includes a wing plate 60 extending from both ends of the frame 50. The wing plate 60 is bent so that one side of the wing plate 60 is connected to the main body 20 So that the main body 20 and the lid 30 can be engaged with each other.

At this time, the wing plate 60 may be bonded to the outer surface or the inner surface of the main body 20 by applying an adhesive to one surface thereof.

Having thus described a particular portion of the present invention in detail, those skilled in the art will appreciate that these specific embodiments are merely preferred embodiments and that the scope of the present invention is not limited thereby, It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the invention, and that such modifications and variations are intended to fall within the scope of the appended claims.
