FIG. 1 is a perspective view showing an appearance of an album of the present invention, and FIG. 2 is a perspective view showing a state in which a front cover of the album of the present invention is opened.

As shown in FIGS. 1 and 2, the album of the present invention includes a representative cover 400 in addition to the front cover 100, the main body 200, and the folding unit 300 It is possible.

The front cover 100 opens and closes the main body 200, and has the same or similar size as the main body 200. On the front of the front cover 100, for example, in case of a graduation album, various recording indications such as a year of graduation, a school, and a degree of graduation can be printed, and various designs and colors can be combined. It goes without saying that such a design and color can be combined with the main body 200 as well.

The folding unit 300 provides a function of connecting one side of the main body 200 on one side of the front cover 100 so that the front cover 100 is foldable on the basis of the main body 200.

In the present invention, the front cover 100 is a flat plate, that is, a panel. Therefore, when the folding unit 300 is described based on the shape of the front cover 100, And a width corresponding to the width of the front cover 100 to the main body 200 and the first and second folding grooves 320 and 330. [

The folding plate 310 is a plate-like structure that forms a sidewall between the front cover 100 and the main body 200 and has a width corresponding to the height of the case 220 of the main body 200 And is positioned between the front cover 100 and the base 210 of the main body 200. The folding plate 310 can be opened or closed while covering or opening one side of the main body 200 together with the opening / closing of the front cover 100.

The first folding groove 320 refers to a groove formed at a boundary between the front cover 100 and the folding plate 310 and the second folding groove 330 refers to a groove formed at the boundary between the front cover 100 and the folding plate 310, And a groove formed in the boundary portion of the folding plate 310.

With this structure, the folding unit 300 can be folded in two stages by the first and second folding grooves 320 and 330, and the folding function of the first folding grooves 320 allows the front side cover The front cover 100 can be completely opened to the same height as the base 210 of the main body 200 by the folding function of the second folding groove 330. [

When the second folding groove 330 is not folded, the folding unit 300 interrupts one side of the main body 200 (the entry side of the photo album) It is possible to open one side of the main body 200 when the folding groove 330 is folded. In particular, when the photo album 10 is housed in the main body 200, the entry side can be opened to provide ease of storage.

The main body 200 of the present invention includes a base 210 having the same height or a flat plate as the front cover 100 and the folded-back portion 300 when the front cover 100 is fully opened, And a case 220 formed at one point developed in the opposite side direction of the unit 300.

The base 210 is a panel in the form of a size corresponding to the photo album 10 to the front cover 100 and is a flat board having the same height as the front cover 100 as mentioned above.

The case 220 is a three-dimensional structure for housing the photo album 10 in a state of having a space 221 therein. More specifically, one side of the four sides is opened to open the folding unit 300 And two side walls 223 and 224 and a top plate 225 rising at a height corresponding to the width of the folding unit 300 in a state of having a surface 222.

The three sidewalls are composed of two first sidewalls 223 contacting both sides of the opening surface 222 and one second sidewall 224 formed on the opposite side of the opening surface 222, The side wall 223 extends obliquely toward the opposite side of the open side, that is, the second side wall, when it extends from one point of the base 210 described above.

The upper plate covering the upper surface of the case 220 while connecting the upper ends of the first sidewalls 223 covers not the entire surface of the base 210 but covers a part of the upper surface of the base 220, A part of the base 210 from the main body 200 toward the folding part 300 is exposed.

According to the case 220, more than two books 10 can be stored in the space 221 according to the height of the first and second side walls 223 and 224 and the width of the folding unit 300, The present invention can be utilized not only as a multi-album but also in a slidably-folded state without attaching a large force to the photo album 10 by the inclined rising shape of the first and second side walls 223 and 224 and the opening function of the folded- (221) of the housing (220) to be stored in the space (221).

In addition, the above-described structure (front cover, folded portion, body) of the present invention can be made of an eco-friendly material such as a paper material instead of a plastic or synthetic resin material and can be recycled as well as being environmentally friendly .

Referring to FIG. 2, a representative photo storage unit 400 is additionally formed on the inner surface of the front cover 100.

The representative photograph storage unit 400 provides a space for storing a single photograph other than the photographs stored in the photo album 10. The representative photograph is a photograph of the user himself / It means a representative photograph of enlarged print.

More specifically, the representative photograph storage unit 400 includes a front surface portion 410 and a rear surface portion 420. The rear surface portion 420 is bonded to the inner surface of the front cover 100, And a display unit 411 with the remainder except for the front cover 100 opened to allow a representative photograph to be observed when the front cover 100 is opened.

At least one side of the combination of the front surface portion 410 and the rear surface portion 420 is opened so that a representative photograph can be stored and taken out through the opening portion in the representative photograph storage portion 400.

The representative picture storage unit 400 functions to provide a symbolic feature that allows a representative picture to be exposed to a user and be viewed first when the user opens the front cover 100 to listen to the album of the present invention.

According to the album of the present invention having such a configuration, not only can the album 10 be conveniently accommodated in a sliding manner, but also has a multi-storage function capable of storing two or more albums 10, and plays an eco-friendly role .

3 is a cross-sectional view showing a further configuration applied to the covering portion and the front cover of the present invention.

As can be seen from FIG. 3, it is possible for the covering portion 500 to be further laminated on the inner surface (preferably the inner surface of all) of at least one of the front cover / the folded portion / the base.

The cover unit 500 provides a function for reinforcing the durability of the album of the present invention. The cover unit 500 may be formed of a thin sheet made of the environmentally-friendly material as described above. However, the covering unit 500 may have a thickness corresponding to or slightly thinner than the front cover 100 It is desirable to ensure durability such as impact resistance.

Furthermore, the covering portion 500 can provide the impact resistance and the refractory properties by interlocking with the front cover 100, which will be described in detail.

Referring to FIG. 3, the covering portion 500 protrudes outward to form a plurality of raised portions 510 for shrinking and expanding. On the corresponding surface of the front cover 100 facing the raised portion 510, It can be seen that the recessed groove 110 may be further included to be recessed inwardly to form a spacing space 550 between the protrusion 510 and the protrusion.

The protrusion 510 provides a physical space to prevent the temperature of the covering portion 500 from being denatured by the temperature / humidity. In other words, the protrusion 510 can cover the temperature / humidity of the covering portion 500 The shrinkage and expansion phenomenon due to the change are concentrated, and consequently the crying and deforming of the covering portion 500 can be minimized.

In addition, in order to form a spacing space (550) between the protrusion (510) and the protrusion (510), a recessed recess (110) recessed inward from a corresponding surface of the front cover It is also possible to minimize transmission to the photo album 10 stored in the main body 200 via the front cover 100. In such a configuration, it is preferable that the recessed groove 110 is formed at a position facing the protrusion 510. When the recessed groove 110 and the protrusion 510 are configured to face each other, The front cover 100 having a larger thickness and volume than the covering portion 500 can be made to have a larger size than the protruding portion 510 to further enhance the heat transfer blocking effect.

In addition to the above-described heat insulating structure, a fireproof block body 600 may be incorporated in the spacing space 550 to further enhance the fire resistance when a fire occurs. The refractory block body 600 may be used as a refractory material covering the surface of the main body 200 or the like including the front cover 100 without being filled only in the spacing space 550 described above. The charging in the spacing space 550 will be described as an example.

The refractory block body 600 of the present invention comprises a refractory core 610 and a refractory nonwoven fabric 620 surrounding the refractory core 610.

The refractory nonwoven fabric 620 of the present invention may be modified cordless reinforced nonwettable nonwoven fabric such as modacryl fiber or PROTEX C fiber. As an example of this refractory nonwoven fabric 620, an open mesh scrim having a first side and a second side may be included, wherein the crimped heat resistant organic fibers are compressed and held in a compressed state by the thermoplastic binder have.

According to this structure, when the refractory nonwoven fabric 620 is exposed to high temperature or flame, the binder in the structure softens and the crimped fibers that are restrained are released, whereby the thickness of the refractory nonwoven fabric is remarkably increased. This increase creates an air bladder within the refractory nonwoven fabric 620, which increases the heat dissipation performance of the refractory nonwoven fabric 620.

Since the crimped heat-resistant organic fibers are compressed in the batt, but not distinctly entangled, the batt can increase its thickness in response to high temperature or flames. Conventionally developed fiber-scrim sheets have been focused on ensuring a high degree of mechanical entanglement of the fibers with other fibers in the scrim and / or the sheet. Typically, such mechanical entanglement is achieved by energizing the fibers forming the sheet and / or the lofty web of the scrim to entangle the fibers and densify the sheet. When such mechanical entanglement is established, the fibers of the sheet are entangled to such a degree that the fibers are not free to move when exposed to heat and flame, and the refractory nonwoven fabric 620 of the present invention can be utilized as a heat dissipating material through such a phenomenon.

The refractory core 610 of the present invention is made of a material such as rubber which is resistant to fire to strengthen the impact resistance in order to prevent the refractory material such as clay, As shown in FIG. In other words, it is possible to manufacture the refractory material such as clay by mixing or impregnating the refractory material in powder form into an elastic body such as rubber. Such a refractory core 610 can combine not only the heat radiation performance but also the shock absorbing performance for absorbing the external impact.

The refractory core 610 of the present invention has a more detailed structure as described below to enhance fire resistance and cushioning.

Specifically, the refractory core 610 has an introduction hole 611 formed in the outer side, that is, in the inner side direction of the surface, and an introduction hole 611 extending in the insertion hole 611 to extend the introduction hole 611 at the end of the introduction hole 611 The elastic reinforcing body 613 is made of a material having a higher elasticity than the refractory core 610 and is accommodated in the opening space 612, . ≪ / RTI > Furthermore, it is possible that an air layer 614 containing air is formed in the remaining space in which the elastic reinforcing member 613 is accommodated in the expansion space 612.

In other words, the expansion space 612 formed at the end of the introduction hole 611 includes an elastic reinforcing body 613 made of a material having a higher elasticity than the refractory core 610 and an air layer 614, The elastic reinforcing member 613 and the air layer 614 are filled in the elastic member 612 to have higher elasticity than when one material is used. Further, since the air layer 614 has an effect of further absorbing the external impact, it is possible to expect an improved level of buffering performance compared with the case of using the conventional single refractory core 610 as a buffer.

 The elastic reinforcing member 613 has a polygonal end shape, and each of the vertexes is in contact with the inner wall of the expansion space 612. The elastic reinforcing member 613 has a rectangular shape, It is possible to further include a path 613b including a plurality of through holes 613a in the body 613 and connecting the through holes 613a to each other in such a manner that air is contained in the through hole 613a .

The shape of the end of the elastic reinforcing member 613 is not limited to a polygon having three or more sides, but the vertexes of the elastic reinforcing member 613 must be in contact with the inner wall of the opening space 612 in order to absorb the shock. That is, a plurality of air layers 614 are provided inside a plurality of through holes 613a, thereby providing a function of securing higher durability from impact.

4 is a cross-sectional view showing a detailed structure for absorbing moisture in the album of the present invention.

In the embodiment of FIG. 3, the album of the present invention is implemented with fire resistance and impact resistance. In daily life, especially in the rainy season, the room is also humid in a high temperature and high humidity environment. In such a humid environment, It is common for this to become dull or discolored because of this.

Accordingly, in order to solve such a problem, the album of the present invention according to FIG. 5 may further include a dehumidifier 700 having a moisture absorbent for absorbing moisture in the air.

Specifically, the dehumidifying part 700 can be housed in the receiving groove 311 extending from one side of the folding iron part 300, specifically the folding plate 310, toward the other side. That is, when the album of the present invention is inserted into a bookshelf or the like, the dehumidifying unit 700 is provided in the folding unit 300 because the folding unit 300 is exposed.

At this time, the dehumidifying part 700 may be further provided with a sealing cap 710 having a plurality of ventilation holes, which are mounted on both sides of the receiving groove 311. The sealing cap 710 may be made of an elastic material such that it can pass through a mesh or moisture, that is, including a vent hole, so that the dehumidifying part 700 can be prevented from being easily separated from the receiving groove 311.

In order to smoothly absorb moisture of the dehumidifying part 700, the moisture absorbent 720 in the dehumidifying part 700 needs to be heated to a certain degree, More configuration is needed to confirm the replacement time.

That is, the replacement guide identifying unit 730 is positioned between the moisture absorbent 720 and the sealing cap 710. The replacement guide identifying unit 730 provides a function of visually recognizing by incorporating a moisture reactive color change component whose color changes due to the moisture absorbed by the moisture absorbent 720. Here, cobalt chloride is a typical example of the moisture reaction discoloration component. Cobalt chloride is generally blue in color, but turns red when moisture is in contact. Accordingly, the replacement timing of the moisture absorbent 720 in the dehumidifying part 700 can be visually identified and grasped through the color change of the replacement guide identifying part 730.

However, when the album of the present invention is inserted into a book shelf together with other books, there is a fear that the replacement guide identifying unit 730 may not be conspicuous, so that the replacement guide identifying unit 730 is physically convex outwardly It is possible to increase the visibility more.

To this end, the sealing cap 710 is made of a stretchable material and can be freely stretched. At this time, it is preferable to apply a desiccant 720 that can increase the volume of the dehumidifying part 700.

4, the moisture absorbent 720 is formed in a multi-layer structure. The innermost core portion includes a main moisture absorbent 721 made of a stretchable moisture absorbent whose volume increases by absorbing moisture, (723) surrounding the surface of the main absorbent (721) so that the components of the main moisture absorbent (721) do not leak out. At this time, it is most preferable that the membrane 723 is also made of a material such as a rubber net, and the membrane 723 made of the rubber net material is formed with a plurality of air holes, In addition, the main absorbent 721 can be wrapped around the main absorbent 721 without breaking even when the main absorbent 721 expands.

Further, between the membrane 723 and the main desiccant 721, a sub desiccant 722 containing a plurality of silica gel crystals may be further included.

The silica gel crystal absorbs moisture before the main moisture absorber 721 and acts as a moisture absorber to prevent the main moisture absorber 721 from expanding too quickly. In addition, since the silica gel crystal serves as a kind of shield, it is of course possible to prevent the main absorbent 721 from flowing out to the outside of the membrane 723. That is, a cross section of the multi-component moisture absorber 720 includes a membrane 723, a subhumidifier 722, and a main moisture absorber 721 from the outermost side toward the inside. As a result, the moisture absorber 720 has a triple structure .

Here, for example, bentonite is a representative example of the main moisture absorber 721. Since bentonite has a property of absorbing moisture in the air to be recovered as crystalline water, it is excellent in absorbing power enough to absorb moisture of 5 to 9 times its original volume, and has a property of increasing the volume and increasing the volume at the same time Have.

Therefore, as the bentonite, a material that increases in volume upon absorption of water is applied as the main desorbent (721). At this time, it is possible to apply bentonite as a single mass, but it is also possible to apply it in finely divided powder form. As described above, the sub-desiccant 722 corresponding to the main desiccant 721 is made of silica gel and does not change its volume, but can spread widely corresponding to the volume change of the main desiccant 721, It can be thin and stretchable such as rubber so that it can be utilized as if it is a single structure without flowing out, and it is possible to prevent the outflow through a membrane 723 having a plurality of vent grooves formed on its surface.

When the main absorbent 721 absorbs moisture and expands, the moisture absorbent 720 itself expands. As a result of this expansion, the replacement guide identification portion 730 pushes the sealing cap 710 outward So that the color change of the replacement guide identifying unit 730 can be visually distinguished more easily.

5 is a flowchart showing a basic process for manufacturing an eco-friendly album of the present invention.

As mentioned above, the albums of the present invention are applied not only to plastic materials and other synthetic resin materials but also to paper materials as raw materials, and also to environmentally friendly properties by using environmentally friendly adhesives when laminating two or more paper materials for thickness guarantee And a method of manufacturing an album having excellent durability by a stronger squeezing performance.

Specifically, the method of producing an album of the present invention means a method of producing a hard cover paper such as the front cover 100, the main body 200 (base and case), and the folding unit 300, A coating step, a drying step, and a lapping step.

The base paper producing step is a method of producing a paper, that is, a base paper, which is a main material having the same constitution as the albums of the present invention, that is, the front cover 100, the main body 200 and the folding unit 300, Board, lysing paper, ceramic powder vapor paper, hard paperboard, or paper that is thicker than ordinary paper, that is, paper that is mainly used for making public albums.

Since such a base is manufactured by a known process, a further explanation will be omitted in the present invention.

The coating step of the present invention is a step of coating the surface of the base paper with a coating solution containing starch as an effective component. The reason for coating the base paper with the coating solution of the present invention is to increase the surface strength and cohesion of the base paper. In particular, in the present invention, it is possible to contain starch as an active ingredient in the coating liquid. In this case, in order to prevent damage to the base paper, it is preferable that the coating of the present invention is coated such that the coating liquid has a thickness of about 0.1 to 0.3 when the thickness of the base paper is 1 and the coating method is spraying, / It is also possible to apply the coating liquid to the surface of the base paper through the chaebol process.

That is, in the present invention, the surface of a base paper is coated with a specific coating liquid to be described later to provide a stronger cohesive force and a bonding force as compared with a paper / paper production method using known starch. The following is a detailed description.

The step of preparing the coating solution of the present invention comprises the steps of preparing a first solution (S100) by mixing starch base containing starch as an active ingredient with sodium hydrogencarbonate and water, mixing the first solution with ethanol, (S200), and adding a calcium salt aqueous solution to the second solution to complete the coating solution (S300).

The first step (S100) of preparing the first solution comprises 10 to 40% by weight of a starch base containing starch as an active ingredient, 5 to 10% by weight of sodium hydrogencarbonate, And 50 to 85% by weight of the first solution.

Wherein the starch base is a material containing starch as an active ingredient, wherein the starch is a material consisting of amylose and amylopectin similar to the cellulosic molecular structure, and the starch is characterized by viscosity due to hydrogen bonding between molecules. Furthermore, it is said that starch is a substance composed of amylose and amylopectin which is similar to the molecular structure of cellulose. Cellulose molecules are also known as a solid structure, which is a material constituting the cell wall of wood. Therefore, in addition to cellulose contained in a base paper made of wood, It is possible to ensure the strength of a harder base paper.

The sodium bicarbonate and water added to prepare the first solution perform the function of extracting the amylose contained in the starch, and the starch particles are not broken by the water added to the starch but are swollen and the amylose can be extracted . The aggregation of the base paper can be further improved by the hydrogen bonding of the amylose thus extracted.

Next, the second solution (S200) is prepared by mixing 85 to 95% by weight of the first solution and 5 to 15% by weight of ethanol with respect to the total weight of the second solution.

This is to neutralize sodium hydrogen carbonate added while preparing the first solution with ethanol, and the second solution prepared by neutralizing the first solution is an aqueous amylose solution containing amylose as an active ingredient.

The step (S300) of adding the calcium salt aqueous solution to the second solution to complete the coating solution includes adding 90 to 95% by weight of the second solution, 1 to 5% by weight of calcium gluconate and 1 to 5% To complete the coating solution.

The calcium salt aqueous solution added to prepare the coating solution contains calcium gluconate as an active ingredient, and the calcium salt contained in the aqueous calcium salt solution functions to prevent the aging phenomenon in which the amylose is aggregated and precipitated by hydrogen bonding . At this time, since the aging phenomenon occurs well at 0 ° C but may occur at 70 to 80 ° C, it is preferable to add an aqueous calcium salt solution which prevents the aging phenomenon of the second solution after the step of producing the second solution.

Herein, the compounds containing calcium salts are very various such as calcium chloride (CaCl ₂ ), calcium carbonate (CaCO ₃ ), calcium hydroxide (Ca (OH) ₂ ) and calcium gluconate , It is preferable to prepare an aqueous solution of calcium salt using calcium gluconate which can be edible and water-soluble without generating harmful substances upon combustion.

The coating solution thus prepared can be expected to have an environment-friendly effect using starch, which is a harmless natural substance, as an effective ingredient, and at the same time, it is ensured that the surface of the base paper immersed due to the viscosity of the starch, .

In addition, in order to improve the durability of the starch base of the present invention and prevent the scattering of the hardened starch, and more uniformly containing the starch in the coating liquid, the starch base of the present invention may be prepared in the steps of preparing emulsion solution (S110) S120) and spraying step (S130), which will be described in detail as follows.

First, an emulsion solution preparation step (S110) is a process of preparing an emulsified solution by mixing 85 to 95% by weight of starch and 5 to 15% by weight of a polyglycerol polyricinoleate solution with respect to the weight of the entire emulsion solution, At this time, the polyglycerol polyphenolic acid is an HLB (Hydrophilic lipophilic balance, which can be regarded as an index indicating whether it is a substance having a tendency to be hydrophilic or lipophilic). It is a small emulsifier and provides stability in emulsifying starch .

Next, the dispersion solvent preparation step (S120) is a process for preparing a dispersion solvent by mixing 1 to 10% by weight of polyoxyethylene sorbitan monostearate (PSS) and 90 to 99% by weight of water with respect to the weight of the total dispersion solvent , Where PSS is the active component of the dispersing solvent in which the emulsified solution is dispersed.

Finally, the spraying step (S130) is a step of spraying the emulsion solution into the dispersing solvent to finally prepare a starch base, whereby the emulsion is sprayed toward the dispersing solvent, whereby the starch is enclosed by the polyglycerol polyphenolic acid The starch base can be stably prepared in a dispersion solvent.

Such a coating solution is coated on the surface of the base paper, and then the coating solution is dried so that the coating solution can be cured. At this time, the drying time and the drying temperature may vary depending on the type of base paper and the thickness of the coating liquid.

In addition, the dried base paper itself can be used as a material for an album such as a front cover, but it is also possible to perform a lapping process for the base paper to secure a thick thickness, and a plywood or a separate hard cover May also be included.

In addition, the album is completed by performing design printing such as graduation year on the base paper or surface treatment such as coating.

As described above, the construction and operation of the sliding type eco-friendly multi album in accordance with the present invention and the manufacturing method thereof are described in the above description and drawings, but the present invention is not limited to the above description and drawings And it is to be understood that various changes and modifications may be made without departing from the spirit of the invention.
