BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infant education paradigm capable of sterilizing in boiling water,

The present invention relates to an educational disposable diaper which can be disinfected in boiling water and a manufacturing method thereof. More particularly, the present invention relates to an educational disposable diaper which can be sterilized by boiling water, The present invention relates to a teaching parlor for infants which can be sterilized in boiling water, which is not changed in shape and can be normally used by infants as before, and a manufacturing method thereof.

Normally, the period of infancy from childhood to the time of school age is the period when daily language acquisition and lifestyle are established through education combined with various plays and lessons.

Newborn babies absorb as much information as they can from outside through infancy. Parents pay much attention to the education of young children who enter these early childhood.

Young children in infancy have the characteristic of absorbing necessary information through the language and drawing that they receive from the outside. Given these characteristics, various learning playgrounds and educational parishes are emerging. In general, it is a textbook for teaching through play, a card-shaped textbook in which a Hangul character, an English alphabet, a word, a picture and a numeral are printed on a sheet, and a plurality of sheets in a book form The textbooks that are made are dominant.

In addition, as another kind of textbook, it is possible to exemplify a puzzle-type text material in which a single large sheet is combined with various pictures, figures or letters to form a completed picture, and a three-dimensional concept And textbooks that provide instruction on hand movements are becoming common.

However, such conventional educational pedagogies have been manufactured and sold without proper consideration of the characteristics of infants.

Children in early childhood are not fully cognitively developed and have not been equipped with objective cognitive abilities about objects, but they have the characteristic of accepting various kinds of information provided from outside very quickly.

The characteristics of this early childhood are that the time to concentrate on one place is very short while the children are jumping around or showing a tendency to distract the surroundings.

As such, young children in infancy do not concentrate on observing the diverse parishes provided by their parents or kindergarten or kindergarten teachers, and even if they show momentary interest, And then picks up another item or goes inside.

In this process, traditional learning parishes may become torn apart, children with distracted spills may spill water, children who eat snacks may pollute learning parishes, or children may put learning parishes into their mouths There were situations that polluted the dioceses in various ways, such as when they were sucked and sucked.

However, conventional learning parishes have had little or no way to remove these contaminants. As a general method, it was common to dry out pollutants in the teaching parish and then gently pour out the pollutants, and there was almost no means to take other methods. In order to remove pollutants, a method of coating the learning diets with a thin vinyl resin or the like has been used, but a method of removing microorganisms such as bacteria caused by the pollutants has also been impossible.

Prior art documents related to conventional learning teaching materials are as follows.

FIG. 2 is a conceptual view illustrating the structure of a soft thermoplastic polyurethane thin film sheet constituting an educational material for infants according to the present invention,

FIG. 3 is a photograph showing a preferred embodiment of the learning diathesis of the present invention.

The present invention relates to a method of manufacturing an educational pedagogy for a child, comprising the steps of selecting constituent data expressing contents suitable for a child in the form of a picture, creating an overall plot, and fixing the contents of the entire plot And preparing a raw material (S 210).

The planning and preparation of the raw material (S 210) selects contents suitable for infants whose identification ability and cognitive ability are weak. It is desirable to express the selected contents in the form of a picture. The contents of the picture are colored, colored, friendly, emotional, intelligent, and easy to recognize, so that they can be processed and used in the next step. It is preferable that the contents of the above picture are formed in a single plot as a whole since the connection relation between the front and rear is clear.

The planning and preparation of the raw material (S 210) prepares a stationary material for learning teaching that fixes pictures and explanatory phrases constituting the single plot in such a manner that they can be specifically observed from the outside. Although the fixture for learning teaching material is made of a plastic material, the "possibility of sterilization" which does not deform the original shape even when "flexibility", "elasticity" and "restorative force" are good and persists for more than 10 minutes in boiling water, It is preferable to use a thin sheet of a soft thermoplastic polyurethane material.

Conventional teaching parishes have also used thin sheet of plastic material. Such a thin sheet of a plastic material is preferably a PET film, a PVC film, a PC film, a PTEG (polyethylene terephthalate glycol) film, a PI (polyimide) film, an ABS film, an OPP film , BOPP film, and the like. Among them, PVC film or PET film is favorably used from an economical viewpoint.

However, the present invention relates to a teaching parlor for infants, and it is an object of the present invention to provide a teaching material for children, which, even if the infant has weak cognitive ability and judgment ability about objects, can use the plastic material to prevent damage to the bookcase It is specially selected and used as the basic material of the bookcase. For this purpose, the present invention has a "flexibility" that allows the bookcase to bend smoothly without being torn, and it also has a "deforming force" that allows the infant to absorb the external force applied by the body of the bookcase and deform its shape And has a "circular recovery force" that causes the external force to return to the original shape when the external force is removed.

In the present invention, the soft thermoplastic polyurethane having the "flexibility", the "shape deformation force" and the "circular recovery force" at the same time is formed into a thin sheet and then used as a base material of a bookcase have. The reason will be described in more detail as follows:

Generally, a polyurethane sheet has a polyol component having a large number of alcohol groups and an isocyanate component having high reactivity to react with each other to form a urethane bond (-NHCO-), thereby forming a polyurethane polymer material having a network structure. Therefore, the polyurethane synthetic resin hardens, and even after receiving heat from the outside, the shape of the polyurethane synthetic resin can not be deformed, and if the heat is applied at a higher temperature, it is carbonized. In this respect, polyurethane materials or polyurethane synthetic resins are classified as thermosetting plastics. The present invention does not use a thermosetting polyurethane material in which the urethane bond forms a network structure as a plastic sheet.

In the present invention, among the polyurethane synthetic resins, only the thermoplastic polyurethane material in which the urethane bonds are linearly arranged is selected and used. In the present invention, the thermoplastic polyurethane material means a synthetic resin polymerized based on a urethane bond, wherein the urethane bonds are linearly arranged to form a polymer material. The thermoplastic polyurethane material is also characterized in that the polyol component and the isocyanate component are combined to form a urethane bond, but have a linear chain structure rather than a network structure. The method of producing the thermoplastic polyurethane material does not need to be particularly limited as long as the polyol component including the polyhydric alcohol and the isocyanate component form a linear urethane bond (-NHCO-).

The present invention uses a soft, thermoplastic polyurethane sheet produced from the thermoplastic polyurethane material in the form of a thin film. This is because the inner bonding structure of the soft thermoplastic polyurethane sheet is simply a linear chain structure and thus it can be stretched freely. When a certain force is applied from the outside, it can be stretched freely to a considerable extent Flexibility "and" resilience. " This also uses a material having a "shape deformation force" that can exist by deforming the original shape when the thermoplastic polyurethane material is subjected to an unfavorable force from the outside.

In the present invention, the thin film sheet made of the thermoplastic polyurethane material is preferably a sheet having a cover, a back and an inlay of a basic book that forms a learning diocese, and has a thickness of 0.02 mm to 1.5 mm. When the thickness of the thin film sheet is less than 0.02 millimeter, it is too thin to perform printing work, and when it is more than 1.5 millimeters, it is too thick to make printing operation difficult. The thin sheet can be used by laminating a plurality of thin sheets considering the thickness of the final bookcase. The flexible thin sheet of the thermoplastic polyurethane material is easily bent when exposed to any external force, exhibiting flexibility, has elasticity to deform the original shape, and is easily deformed when the external force is removed. It has the ability to recover the original shape.

In the present invention, the "flexibility" and "elasticity "," shape deformation force "and" original shape recovery force "of the thermoplastic polyurethane material are used to perform a bending test as a primary objective performance, It is desirable to perform a test.

In the present invention, the bending test is performed to confirm whether or not the test object indicates a normal state even after 20,000 or more bending tests are performed after mounting the test object on the test apparatus. In the bending test, the sheet to be tested is cut to a predetermined width and length, and the left or right wall surface is moved in a state where the cut sheet is mounted in the sheet, so that the sheet mounted in the sheet is bent forward or backward And then the wall surface is returned to the original position again, whereby the sheet is unfolded to its original state. If the bend test of the soft, thermoplastic polyurethane material is judged to be defective at less than 20,000 cycles, the infant may lack the flexibility and lack of flexibility in situations where it throws away the teaching parlor, It is not desirable because it will be worn. 20,000 times of the bending test may be a first criterion for judging suitability as a material of the learning diathesis of the present invention.

In the present invention, the warpage test is performed to confirm whether or not the test object indicates a normal state in a state where the test object is twisted in the forward and backward direction more than 20,000 times after the test object is mounted on the test device. The warp tester is configured to cut a sheet to be tested to a predetermined width and length, rotate one of the bars to the left or right by a predetermined angle in a state where the cut sheet is mounted inside the test apparatus, And returning the rod to its original position, thereby allowing the sheet to unfold to its original state. 20,000 times of the distortion test may be a second criterion for judging suitability as a material of the learning diathesis of the present invention.

By satisfying both the first condition by the bending test and the second condition by the torsion test, the present invention can be restored to its original shape even when the infant is free to play or throw away.

As a result, the present invention can be applied to a case in which even if a child with weak cognitive ability throws a child booklet or plays with a rough play as he feels, the bookcase of the teaching diary is not torn, broken or folded The present invention has been made to solve the above problems by utilizing a combination of the linear chain structure of the soft thermoplastic polyurethane sheet. will be. The prior art does not disclose such a technical purpose and a solution thereof at all.

The present invention relates to a method for digitizing learning contents suitable for young children and fixing the learning contents to a soft sheet made of a material having good flexibility and resiliency after performing the planning and preparing steps of raw materials, (S 220) of sterilizing the content of the learning diary, which provides a basis for sterilizing the learning diaries made up of the learning contents by making the immobilized data of the learning contents uniform, .

The step of sterilizing the contents of the learning diary (S 220) is a task of digitizing the contents suitable for young children. It is preferable that the learning contents mainly include photographs or pictures that can be understood by young children or improve the cognitive abilities of infants and it is preferable that the contents of the pictures or pictures are summarized and expressed in brief sentences . The photograph, the figure, and the like and the sentence are arranged in the same page. The digitalization of the learning contents corresponds to a prerequisite for a digital printing operation in order to provide a clear impression to a child. The digitizing work of the learning contents can be performed by scanning or photographing the photographs, pictures and sentences, or in a conventional manner.

The step of sterilizing the contents of the learning diary (S 220) is performed in such a manner that the digitized learning contents are specifically fixed on the surface of the contour so that the infant can see and recognize the learning contents with their eyes . It is preferable to use a soft thermoplastic polyurethane material as described above and to form the thin sheet 110 having a thickness suitable for a child learning diagonal. It has already been shown that the digitized learning contents are made of color colors and consist of photographs, pictures, and a few sentences. The immobilization operation can be achieved by performing digital printing on the surface of the thin film sheet 110 composed of the soft thermoplastic polyurethane material. The thin sheet 110 is preferably made of a soft thermoplastic polyurethane material having a thickness ranging from 0.2 millimeters to 2.0 millimeters. In the case of a thin material, the thin sheet 110 may be formed by laminating them. The thin sheet 110 is preferably made of opaque white material on the front printed layer 112 on its surface and on the back printed layer 114 on its back surface.

In order to easily remove the contamination even if the infant is contaminated by water, confectionery or other food during use, the step of sterilizing the contents of the learning diary (S 220) And a tamper-resistant work that can protect the learning contents fixed on the surface of the robot from external influences. The protective operation of the learning contents is performed by forming an upper protective layer 120 protecting the front printed layer 112 on the surface of the thin sheet 110, RTI ID = 0.0 > 114 < / RTI > The transparent upper surface protective layer 120 and the rear surface protective layer 130 can visually show the information of the learning contents at the bottom inside thereof visibly to the outside while the content of the contents from the external scratches and graffiti or contaminants It prevents and protects you from being damaged.

The step of enabling sterilization of the contents of the learning diary (S 220) is a step of collecting data on the above-mentioned tasks of fixing the learning contents and preventing the contents from being damaged, And the like. The uniformization of the learning contents can be realized by cutting each of the separately prepared learning contents and soft thermoplastic polyurethane thin film sheets into the same size.

As described above, the step of sterilizing the contents of the learning diary (S 220) includes the steps of specifically fixing the digitized learning contents to the surface of the outer contour and the operation of securing the fixed learning contents to external influences The process of cutting off the anti-tampering operation and the contents of the anti-tampered learning in consideration of the overall unity and uniformity can give flexibility and resilience as a whole and is put into boiling water for 10 minutes or longer. If it returns to room temperature, it still retains flexibility, resilience, and resilience.

The present invention includes a completion step (S 230) as a learning teaching apparatus for sequentially joining the data after completion of the sterilizing enabling step and finishing work as a child learning teaching apparatus.

The completion step (S 230) as the learning diocese can be accomplished by collecting the completed works of the diocese described above, arranging them in the order of constructing the stories, and joining them together.

The completion step (S 230) as the learning diagonal can be completed by binding the front cover, the book cover as the inlay, and the back cover in the order of binding after they have performed the joining operation. The bookbinding method can be performed in a conventional manner.

The present invention preferably includes an additional supplemental step (S 240) for checking and supplementing additional items as a final learning diary.

The additional supplementary step (S 240) is a process of checking and examining defects as infant products and whether defective products are generated in the manufacturing process. The additional replenishment step may be performed in a conventional manner.

Hereinafter, the learning diathesis of the present invention according to the present invention will be described in more detail.

<< Example 1: Bending test (horizontal and vertical directions) >>

The present inventors have found that a soft sheet 110 of a thin film (thickness of 1.0 +/- 0.05 mm) is produced by using a thermoplastic polyurethane and then an upper protective layer 120 and a back protective layer 130 are formed thereon, Thereby completing a single bookcase (100).

The one bookcase 100 was attached to the bending tester 200, and a bending test was performed. The bending tester 200 has a space for inserting 10 samples into one apparatus, and there are about 9 split rods 202 in the space. The left side of the space includes a copper plate 210 on the left side of the space, And a right side movable copper plate 230 is formed on the right side of the movable plate 210 and a fixed plate 220 fixed to the center of the movable plate 210. The movable plates 210 and 230 and the fixed plate 220 are provided with bookcases 100 And a plurality of mounting gaps 204 for holding the mounting gaps 204 are formed. The book holder 100 is fixed in the mounting gap 204 in the lateral direction and the longitudinal direction and then the left movable plate 210 is moved in the right direction and the right movable plate 230 is moved in the left and right direction, To move it in the left direction and then to the original position again. At this time, since the book shelf 100 is pushed from the left or right side to be pressed, it is bent forward from the central portion. When the left and right movable plates 210 and 230 are again reduced to their original positions, It was to be unfolded originally. Using this operating principle, the bending tester 200 allows the flexible sheet to be bent and unfolded several thousand times repeatedly, so that the characteristics of the bending phenomenon of the bookcase 100 can be objectively confirmed.

The inventors of the present invention have found that the bookcase 100 is inserted and fixed in both mounting gaps 204 of the bending test machine 200 in the transverse direction and the longitudinal direction and then the bending test machine 200 is operated, And the bending test was performed by moving the copper plate 230 in the right and left directions.

The present inventors conducted the bending test machine 200 and then performed 2,000 times. After that, the bookcase 100 was taken out and examined, but no abnormality could be found.

FIG. 4A is a photograph showing an example of a bending test according to the first embodiment. FIG.

<< Examples 2 to 7: Bending test (horizontal and vertical directions) >>

The inventors of the present invention mounted the bookcase 100 on the bending tester 200 in the same manner as above and performed 4,000 times, 6,000 times, 10,000 times, 15,000 times, 20,000 times, 30,000 times, (200). However, no abnormality could be found in all the bookcases 100.

<< Example 8: Torsion Test >>

A book 100 was completed in the same manner as in Example 1, except that a polyurethane thin film sheet of the same material as in Example 1 was used.

The bookcase 100 was mounted on the warping tester 300 and a warping test was performed.

The twist tester 300 includes a plurality of twist rods 310 capable of twisting the soft sheet at a predetermined angle on one side of the hollow space, . Since the center hinge pin 302 is provided at the central portion of the twist rods 310, the twist rods 310 are rotated by a predetermined angle (usually about 15 degrees) to the left or right in the vertical direction, (Usually about 15 DEG), and can be returned to its original position.

On the other hand, a plurality of fixed rods 320 are formed on the opposite sides of the plurality of twist rods 310. The fixing rods 320 are not provided with a center hinge pin at the center thereof. The twist rods (310) and the fixed rods (320) have a mounting gap (304) in which the soft sheet can be fitted and fixed. In order to perform the twist test of the soft sheet, the soft sheet is fixed to the mounting clearance 304, and then the twist rods 310 are guided to rotate in the left or right direction, and are then reduced to their original positions . At this time, the soft sheet rotates while moving the twist rods 310 in the left or right direction, while the fixing rods 320 are fixed, so that the soft sheet is twisted in the torsion tester 300 It will be unfolded again in the original direction, twisted again in the opposite direction, and then unfolded back to its original position, and this twisting action is repeatedly performed. Using this operating principle, the torsion tester 300 allows the soft sheet to be repeatedly twisted and unfolded several thousands of times, so that the characteristics of the twist of the soft sheet can be objectively confirmed. Generally, a general plastic card performs such a warpage test about 4,000 times, and then, if there is no abnormality in the card body, a warp test acceptance judgment is made.

The inventors of the present invention have found that the bookcase 100 is inserted in the mounting clearance 304 of the warpage tester 300 in the transverse direction to be fixed to the mounting clearance 304 of the warpage test apparatus 300 and then rotated about 15 ° to the left, The user is returned to the original position, and the operation is repeatedly performed.

The present inventors conducted the warp tester 300 for 4,000 times and then took out the bookcase 100, but found no abnormality.

FIG. 4B is a photograph showing an example of a distortion test performed according to the eighth embodiment.

<< Examples 9 to 14: Torsion Test >>

The inventors of the present invention installed the bookcase 100 again in the same manner as in the eighth embodiment and performed 5,000 times, 6,000 times, 10,000 times, 15,000 times, 20,000 times, and 30,000 times in the twist tester 300 And taken out of the warp tester 300, respectively. However, no abnormality was found in all the soft sheets.

<< Example 15: Test for distortion in boiling water >>

The inventors of the present invention conducted the sterilization test by putting the infant educational diaphragm according to FIG. 2 into a domestic pot, pouring water, boiling water from the domestic pot by turning on the gas range, and so on. There is no test method for inserting the study book or the educational parish into the water and conducting the sterilization test in the boiling water so far, and it is revealed that the present inventors have made the inventions arbitrarily.

FIG. 5A is a graph showing an initial state in which the infant educational diaphragm of the present invention is inserted into the inner water of a domestic pot, and FIG. FIG. 5B shows a state in which the water in the domestic pot is boiling, and FIG. 5C shows a state in which the other bookshelves of the present teaching parlor of the present invention are handed over and sterilized.

As a result of the observation by the present inventors, it was found that, in the early stage, the infant educational diaphragm of the present invention was slightly floated in the water, and when the household pot was heated and boiled, a lot of air bubbles rose up, It showed floating over the boiling water as a whole. Also, since the bookshelves of the infant education parish were observed to be stuck together, they were handed over to the bookshelves of the other pages using the forceps and sterilized in boiling water.

After such a process was performed for about 10 minutes, the gas range was turned off and the baby learning diathesis of the present invention was taken out from a household pot. However, the above-mentioned educational pedagogy of the present invention, which had completed the sterilization work, could not find any abnormality in appearance, and after a lapse of about one minute, it was felt by touching with the hand but felt a little warmth. Also, no distortion occurred at all and no deformation occurred.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited thereto. Is limited.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the present invention.
