The present invention has a box (hereinafter referred to as a box) shape during use in use of an object, a part, or a product (hereinafter referred to as contents), and is folded in a rectangular state during storage, so it is limited when not in use. It has the effect of saving space, and it is also convenient for the translucent slope of all the boxes, and above all, it is possible to prevent damage to the product due to frictional charging (electrostatic) that occurs during transportation or movement in storing or transporting the contents in the box. It would be safe to transport while suppressing.

Using the four-sided semi-transparent folding box with antistatic function manufactured in this way, the volume occupied when not in use is reduced, which saves storage space, and the contents stored in the box can be checked in any direction, which is not only convenient but also efficient. It is characterized by the fact that it is possible to nationalize and clean products by preventing the foreign matter from adhering to the contents stored in the box by the friction electricity which can inevitably occur due to the shaking of the internal contents during use or movement. It has the advantage that it can provide to the user. In particular, electronic components supplied to electric and electronic companies are providers of the cause of defects of final products by static electricity, and static electricity may cause serious problems as follows. It is considered to be a cause of failure due to disconnection due to generated voltage (hundreds of thousands of V / sec), malfunction of electronic devices by static electricity, fire, and foreign matter adhesion.

Therefore, this product prevents the damage of the contents of the box or adhered to foreign substances by saving the storage space during unused, improving the productivity by translucent, and preventing the frictional electricity (antistatic or antistatic function) caused by the shaking of the contents in the box during transportation. It relates to the design of a product that can be.

If you look at the folding box technology or products manufactured before,

The products, patents, and practical models developed or designed with the main focus on the convenience of users by making the box easy to fold and fold, are the mainstream, There is no technology and product related to the problem.

1) The folding function box designed in Korean Utility Model Application No. 20-1982-0005428 has advantages in terms of space saving effect when not in use.However, when the static electricity occurs when moving and storing electronic components or products sensitive to static electricity Has the disadvantage of not being able to prevent damage.

2) The products invented or designed to check the contents established in the box by attaching transparent doors on one side or the opposite side of the folding box have the advantages of verifying the contents than the existing opaque products, but to produce transparent doors. Due to the increase in mold cost and the increase in product price due to the necessity of additional assembly, there is a disadvantage in that the price competition falls and only one or two sides of the transparent door are attached.

3) Looking at other developed technologies and products, the contents of the boxes, especially the parts and products produced by electrical and electronic companies that are sensitive to static electricity, are stored in the box and can be derived. It is known that the concept of a product, technology or folding box is not known yet. It has been developed with a focus on simplifying assembly and folding.

Therefore, the contents contained in the box developed and devised by the previous technology or product are subject to frictional charging (electrostatic charge) due to shaking during transportation. There is a phenomenon in which static electricity is generated by separation and rearrangement of charges due to friction or movement of contact positions between two objects due to charging by friction. For example, electronic products such as TVs use electricity and generate electrostatic attraction (electrostatic or electric and magnetic fields), which are stabilized by electrostatic bonding with surrounding dust. Therefore, dust sticks well when an electric field is generated. According to the literature, the concentration of aerosols by electric fields (electrostatics) is due to the polarization force but is actually proportional to the size of the surrounding aerosols, which is effective only for large aerosols, but with very small particles in the nanometer range. For aerosols, another mechanism has been reported to work with electric fields (electrostatic fields). In other words, very small aerosols usually have electrons and because of their very small size, they have a great mobility in the electric field. So these aerosols are concentrated in static electricity (electric field). The conclusions made by this document are: "The concentration of aerosols in the air can be explained on the basis of basic physics," and "If aerosols contain carcinogens that we know or are likely to have. The relationship between exposure to electric fields (electrostatics) and the risk of cancer. " In this case, if static electricity is generated in the contents stored in the box while moving, very fine foreign matter (aerosol) may adhere to the product, which may act as a defect of the final product, and such fine dust is not easy to remove. However, existing foldable products were mainly assembled and manufactured with plastic products, but they were not treated with electrostatic discharge (ESD), which had serious problems. In the case of over-finished products, there was a problem that caused the loss of manufacturing suppliers due to the lack of aesthetic appearance by the attachment of foreign substances on the surface of the product.

The present invention is devised to solve the above problems;

The present invention solves the conventional problem by preventing the accumulation of foreign matter on the surface of the contents to discharge static electricity generated in the contents contained in the box as the main purpose of the present invention.

Thus, the present design uses a naecheom type polymer resin (hereinafter referred to as the polymer resin itself, the said name card producing naecheom resins been type polymer resin so as to have a conductivity) been fabricated of conductive material added to the box the internal surfaces 10 ^{6 ~ 11} Ω Manufactured to have a resistance of about / cm ² , to prevent the phenomenon that the charged foreign matter sticks to the storage contents by the present invention by having an antistatic function (hereinafter referred to as the antistatic function), and also the charged foreign matter The present invention provides a product which is designed to be easily removed even if foreign matters stick to the contents by a mechanism that can prevent the sticking of the contents.

And another object of the present invention is a box with a translucent slope, which not only brings convenience to the user as the contents can be checked in any direction, but also brings the efficiency of the production line to double the efficiency of mass production, and the present invention is not used, namely, During storage, the space occupied by the folded rectangular state is reduced, so that the storage space can be saved, and when the user wants to use the box, it is provided to make the box form by simply lifting both handles upwards.

The constitution, the embodiment and the working example of the preferred design of the present invention for achieving the above object are as follows.

First, look at the preferred configuration and embodiment of the present invention.

Regarding the completed folding box 1 of the present invention, as shown in FIG. 1, the cover 9 is mounted on the upper frame 4, and foreign matter flows into the box after storing the contents. It is an invented product. The cover can be fixed by hinge or hinge. In general, in a workshop equipped with a high clean facility such as a clean room, the cover 9 is removed to enable use.

The folding box (2) of the present invention with the cover removed is a rectangular box as shown in FIG. 2, and the four sides (5, 6, 7, 8) of the box are manufactured by using an internal addition type polymer resin. It is designed to achieve antistatic function and 4 sides translucent function at the same time.

1 is a state box (1) of the four-sided translucent folding box with the antistatic function produced by the present invention is unfolded, four sides translucent, four-sided translucent plate (5, 6, 7, 8) Is made of a structure that is fixed by the lower plate 4 and the upper frame (4).

1, 2, 3, and 4, the front translucent plate 5, which is folded inward, is the upper bending semi-transparent plate 51 and the front of the translucent plate. It consists of a semi-transparent plate of the translucent plate 52, the rear semi-transparent plate (7) folded inwards is also a semi-transparent plate of the rear semi-transparent plate (71) and the lower semi-transparent plate (72) It is formed by two translucent plates to function as a folding function, and both side translucent plates (6, 8) is to be formed by the folded box (10) folded box 2 due to the upward direction. In addition, the opening part of the upper frame 3 is configured as a cover having an opening / closing function to prevent the foreign matter from entering the inside at all during storage or moving for a long time after the contents are stored.

In order to realize the main antistatic function of the present invention, an internal addition type polymer resin material containing a conductive material in a thermoplastic resin was used.

As the resin used as the main component of the thermoplastic resin, acrylonitrile-butadiene-styrene resin, polybutylene terephthalate, polyethylene terephthalate, polyethylene, and polypropylene are used. The resin has also been used by blending two or more components.

The thermoplastic resin is used in an amount of 99.5 to 75% by weight, preferably 99.5 to 90% by weight based on the total weight of the resin composition. If the amount of the thermoplastic resin is less than 75% by weight, the workability is poor and mechanical properties cannot be maintained. Fabrication of a strong molded article is difficult, and the conductivity is lowered at 99.5% by weight or more.

The main component of the conductive material is; Indium Tin Oxide (ITO), 1 selected from Poltaniline, Polyethylenedioxythiophene, Polypyrole, Polythiophene, Poly (p-phenylene), Polyacetylene, Poly (p-phenylene vinylene), Polythienylene vinylene, Polyisothianaphyhene, Poly (p-phenylene sulfide) Used for more than one species; As the surfactant, a cation selected from a quaternary ammonium cation surfactant, trimethyl ammonium ethoxide, trimethyl ammonium butoxide, trimethyl ammonium phenoxide, trimethyl ammonium P-chloro phenoxide, and trimethyl ammonium lauoxide which are antistatic agents Surfactant; and (3-lauramidopropyl) trimethylammonium methyl sulfate which is an anionic surfactant; antistatic agent is anionic surfactant such as carboxylic acid type, sulfate ester type, sulfonate, phosphate ester type; alkyltrimethylammonium chloride, dialkyl chloride Cationic surfactants such as methylammonium and benzalkonium chloride; amphoteric surfactants such as alkyldimethylaminoacetic acid betaine, alkylamide dimethylaminoacetic acid betaine, 2-alkyl-N-carboxy-N-hydroxyimidazolinium betaine Polyoxyethylene type, polyhydric alcohol ester type, ethylene oxide propylene oxide At least one selected from nonionic surfactants such as block copolymers; natural surfactants such as lecithin; and polymeric surfactants.

And the amount of the conductive material for the antistatic function pursued in the present invention is 0.5 to 25% by weight, preferably 0.5 to 10% by weight.

The internal additive-type polymer resin used in the manufacture of the four-sided semi-transparent folding box having an antistatic function of the present invention is mixed with each of the above components, or each of the mixed components is a pelletized compound composition resin using an extruder at 150 ~ 350 ℃ To manufacture.

According to the required characteristics of each product, the internally-type polymer resin thus formed is provided as a desired final product by press working and extrusion molding, in particular injection molding.

In addition, according to the present invention, a box made of an internal additive type polymer resin is more excellent in durability, electrical resistance, etc. than a coating type box, and exhibits a translucent effect on all four sides of the box by exhibiting its translucent color. In addition, the contents contained in the manufactured box can be easily identified from the outside.

Hereinafter, a preferred working example of the present invention will be described in detail. This preferred working example allows for a better understanding of the objects, features and effects of the present invention.

The folding box made of the above-mentioned internally-added polymer resin is translucent on four sides so that the contents stored in any direction can be seen, and developed or devised by attaching transparent doors separately on the existing one or two sides. It has the following advantages over products.

Existing products with transparent doors on one or two sides are inconvenient that cannot be checked in the direction that the transparent door is not attached, and are a means for attaching transparent doors. Many of the shortcomings such as the lack of price competitiveness due to the increase in manufacturing cost and the decrease in production volume are designed to provide convenience and profit in the process line to both manufacturers and users.

The folding box, which is designed by applying the internally-type polymer resin, is a product that provides antistatic function and can quickly remove static electricity (friction electricity) that can be generated during transportation of the stored contents. Especially, it is used for electric and electronic products. It is a technology designed to prevent damage to the parts.

To solve the problem caused by the adhesion of foreign substances by static electricity,

In the present invention, the metal sphere theory is modeled as a way to remove the foreign matter easily even if the foreign matter sticks to the contents by a mechanism that prevents the substance from falling off when the charged foreign matter sticks to the contents. In metal spheres, there is a tendency for the electric field to be zero. Therefore, in the present invention, the box itself is made of an internal additive type polymer resin, or a box manufactured by coating the inside of the box manufactured by using a general plastic resin with a conductive material becomes a folding box having an antistatic function.

The triboelectric decay mechanism of the present invention is as follows.

The folding box with antistatic function designed in the present invention has an inner surface of (-) charge and the outside of (+) charge, so that the friction electricity generated in the contents while moving is loaded and folded with an antistatic function It will exit out of the box. With this mechanism, the internal electric field tends to be zero, regardless of the shape of the box. Assuming that there is a charge and an electric field in the conductor in the initial state, the presence of the electric field means that the charges can move under force. That is, the charges in the conductor begin to move under the influence of the electric field and the movement of the charges is in the direction that causes the internal electric field to become zero. It is described in the magnetic and electric fields section of physics that the electric field of the conductor surface is perpendicular to the surface.

Therefore, the frictional electricity generated during the movement of the contents stored in the folding box having the antistatic function, that is, the static electricity or the electric field, can protect the product from the static electricity generated by moving out of the box. The dusts can cause dirt on the surface of the contents due to the nature of sticking to the surface of static electricity and damage caused by the difficulty of removing when the charged fine dust adheres to the surface of the contents, and especially the contents are sensitive to static electricity such as electronic components. Electric and electronic companies that handle incoming products can prevent damage to the final product.

As a way to identify the mechanism as described above, in the present invention, by placing the electric product generating an electric field outside the box to be measured by measuring the degree of electric field attenuation in the manufactured folding box having an antistatic function, the electric field meter (E Tester, NIT) was used to measure the electric field in the center of the box.

As a result of measuring with a commercially available folding box (# 1) or two transport boxes (# 2) and a box (# 3) manufactured according to the present invention, the folding box (#) or the transport box (# 2) In this case, about 50V / m was measured, but the folding box (# 3) having an antistatic function manufactured according to the present invention was measured at 3V / m or less, and the box manufactured by the present invention measured the electric field (electrostatic) present therein. It turns out to have an extinction function.

Surface resistance (KS M 3015-1997) is determined by the test conditions; Applied voltage 500V, 60 seconds, 20 ± 2 ℃, 65 ± 2% RH, test equipment; It was TOA SME-8311, D1 = 1.96cm , 10 8 ~10 10 Ω at D2 = 2.41cm, the half-life (KS K 0555-2000, A method) test conditions; At 20 ± 2 ℃ and 40 ± 2% RH, the antistatic performance was very good at less than 2 seconds.

Inde surface resistivity measurements are squeezed between the electrodes of the sample charged in the sample 40-50 seconds, is stopped when a surface resistance of 10 ¹² Ω or less Compliant that after one minute to obtain a specific resistance value by measurement, calculation, this contrivance is ⁸ to 10 Measured by 10 ¹⁰ Ω it was found to be very excellent.

The frictional charge was measured using a SIMCO-FMX002 meter. As shown in FIG. 5, the measuring method of the plate manufactured by the present invention is as follows.

1) Draw a circle with a diameter of 10cm for each measuring point of the prepared plate.

2) Measure the large voltage before rubbing with paper.

3) Friction (0.5HZ) 20 times within the point range with 4 ~ 5Kg load using printing paper for each measuring point.

4) Measure the friction point voltage within 1 second of the rubbing point,

The five voltages on the plate to be measured were used to determine the distribution of the voltages at each measurement site. Measurements made in the form of boxes rather than plates yielded even better results.

Point Before After One O volt 0 Volt 2 0 Volt 0 Volt 3 0 Volt 0 Volt 4 0 Volt 0 Volt 5 0 Volt 0 Volt

Therefore, the main method of measuring electrostatic discharge (ESD) in the present invention is as follows.

[Field measurement]

It measures electric field component of electromagnetic wave, and it is digital method with frequency range 15Hz ~ 2.0KHz, measuring range 1V / m ~ 1,999V / m, error rate ± 5dB.

[Electrostatic measurement]

Electrostatic meters measure the intensity of static sources, and the apparent charge (unit = V) is a measure of the potential for destruction by the induction of generated electromagnetic fields.

[Surface resistance, Rs, ohms per square unit: Ω / cm ² , Ω / sq]

Conductivity plays an important role in the amount of static electricity generated in a material and is a measure of the material's ability to release static electricity, typically the resistive properties of the product used to protect it from ESD.

Half life measurement

The high voltage half-life measures the time when the applied voltage is 8KV, applied for 60 seconds, and when the applied voltage is stopped, the large voltage is reduced to 1/2. The high voltage half-life is evaluated as suitable when it is within 2.0 seconds.
