Storage container

The present disclosure generally relates to a storage container. More specifically, the present disclosure relates to a storage container that can easily and easily accommodate a flexible glass-bonded substrate in a wound state.

Glass, as an optically transparent, hard and brittle material, can be fabricated into a substrate having a thickness of several millimeters and used as a variety of industrial products. Recently, as various technologies have progressed, the thickness of glass used for this substrate has gradually decreased. In particular, the current development of glass manufacturing techniques used by specialty glass manufacturers for special composition and surface quality management has reached that ultra-thin flexible glass substrates can be manufactured to have a thickness of 0.3 mm or less and can be wound into a roll shape. s level.

At present, ultra-thin flexible glass substrates have been investigated for their potential for several applications in the early stages of their development. The use of ultra-thin flexible glass substrates is expected to increase to have applications in various fields such as health care devices, wearable devices, and the like, and display substrates using ultra-thin flexible glass substrates. In various applications of ultra-thin flexible glass substrates, the use of ultra-thin flexible glass substrates as the outer layer (skin) of other substrates has recently increased. Ultra-thin flexible glass substrates are used as an outer layer for other substrates. Applications or techniques use a variety of bonding techniques to bond ultra-thin flexible glass substrates to industrial materials with partial thicknesses such as steel, wood, plastic and poly-p-phenylene. Ethylene glycolate (PET). Therefore, the advantages of glass, such as high level of surface hardness, ease of cleaning, barrier function, and the like, are combined with the characteristics of industrial materials, whereby a flexible glass bonded substrate having various excellent characteristics can be manufactured.

Flexible glass bonded substrates must be packaged and shipped for sale or use. In this regard, there is a need for a storage container that is dedicated to flexible glass bonded substrates.

To this end, in the related art, a flexible glass bonded substrate is wound on a hollow cylindrical core, and the outer cover is wrapped around the flexible glass bonded substrate to protect the flexible glass bonded substrate from being exposed to the outside. Shock.

However, when the flexible glass bonded substrate is loosened, it may be difficult to peel the flexible glass bonded substrate from the core based on how the proximal end of the flexible glass bonded substrate is fixed to the core. After loosening the flexible glass bonded substrate, it may be somewhat difficult to peel the cover from the flexible glass bonded substrate. Therefore, there may be a problem of reducing the life of the cover. In short, in the related art, a method of accommodating a flexible glass bonded substrate or a storage container dedicated to accommodating a flexible glass bonded substrate may have a problem of being inconvenient to the user.

According to the present disclosure, the core can wind or loosen the flexible glass bonded substrate when the magnetically fixed flexible glass bonded substrate has a proximal end in a fixed position. Therefore, it is easier and simpler to wind and accommodate the flexible glass-bonded substrate or to loosen and use the flexible glass-bonded substrate in a more reliable manner. When the flexible glass bonded substrate is wound or loosened, the physical force applied to the flexible glass bonded substrate 10 is minimized, thereby protecting the flexible glass bonded substrate from damage.

Further, according to the present disclosure, the core is disposed in the container body, and thus the flexible glass bonding substrate wound around the core is also housed in the container body. Therefore, the flexible glass bonding substrate can be fundamentally prevented from being contaminated by external dust or impurities.

Moreover, in accordance with the present disclosure, the core is constructed to minimize its weight so that the storage container can be transported more easily.

Further, according to the present disclosure, the proximal end of the flexible glass-adhesive substrate is introduced to the container body by being guided to the core along the inclined surface of the guide portion provided to the bottom surface of the container body.

Further, according to the present disclosure, in the process of winding a flexible glass bonding substrate as a blackboard or a whiteboard, a brush provided on the inner upper surface of the slit of the container body can be used to adhere the surface of the substrate to the flexible glass. Easily erase text and more. When the flexible glass bonded substrate is wound, impurities may also be removed from the surface of the flexible glass bonded substrate. Therefore, it is possible to prevent the ultra-thin glass sheet forming the surface of one of the flexible glass-bonding substrates from being broken by impurities when winding the flexible glass-bonding substrate.

Further, according to the present disclosure, the flexible glass-adhesive substrate can be simply and easily wound or loosened by rotating the core forward or backward using a handle that is convex from the outer wall surface of the container body.

The method and apparatus of the present disclosure are set forth in the accompanying drawings and the description of the claims.

Reference will now be made in detail to a storage container in accordance with an exemplary embodiment of the present disclosure, which is illustrated in the drawings and described below in order to enable a person of ordinary skill in the art Revealed.

In this document, reference should be made to the drawings, wherein the same reference numerals or In the following description, a detailed description of known functions and components incorporated herein will be omitted in the case of obscuring the application of the present disclosure.

Hereinafter, a storage container according to a first exemplary embodiment of the present disclosure will be described with reference to FIGS. 1 and 2. As shown in FIGS. 1 and 2, the storage container 100 according to the first exemplary embodiment is a container in which the flexible glass-adhesive substrate 10 is accommodated, so that the volume of the flexible glass-adhesive substrate 10 is minimized to facilitate For storing or transporting the flexible glass bonding substrate 10. Here, the flexible glass bonding substrate 10 includes a base substrate 11 and an ultra-thin glass sheet 12 bonded to the base substrate 11.

When the flexible glass bonding substrate 10 is used as, for example, a board (blackboard or whiteboard), the base substrate 11 may be formed of a magnetic material based on, for example, steel, wood, plastic or polyethylene terephthalate (PET). The base substrate 11 is freely attached to or detached from a wall formed of metal. The thickness of the base substrate 11 may range from 100 μm to 5000 μm. The thickness of the ultra-thin glass sheet 12 may be less than or equal to 0.3 mm. The ultra-thin glass sheet 12 is bonded to the base substrate 11 by the adhesive layer 13. The ultra-thin glass sheet 12 is formed into a surface of the flexible glass-adhesive substrate 10 due to its excellent characteristics such as a high level of surface hardness and easy cleaning to be used as a sheet. The use of the flexible glass-adhesive substrate 10 as a sheet material is merely illustrative, and the flexible glass-adhesive substrate 10 can be applied to various fields.

In order to accommodate the flexible glass bonded substrate 10 as described above, the storage container 100 according to the first exemplary embodiment includes the container body 110 and the core 120.

The container body 110 forms the outer casing of the storage container 100. The container body 110 has a hollow interior space in which the core 120 is disposed and the flexible glass bonded substrate 10 is housed. Although the container body 110 is depicted as a box shape, the container body 110 may have a cylindrical shape. The container body 110 has a slit 111 as an inlet through which a flexible glass bonded substrate is introduced and withdrawn. Preferably, the slit 111 is formed at the bottom of the front surface of the container body 110, so that the flexible glass-adhesive substrate 10 can be easily introduced and withdrawn. When the flexible glass bonding substrate 10 is used as a plate material, unerased characters or the like may remain, or impurities may still adhere to the upper surface of the flexible glass bonding substrate 10 (based on the paper sheets of FIGS. 1 and 2). , that is, the surface of the ultra-thin glass sheet 12. Thus, the brush 112 is disposed on the inner upper surface of the slit 111 of the container body such that the brush 112 is in contact with the upper surface of the flexible glass bonding substrate 10. For example, the brush 112 may have the form of a curtain that extends in the longitudinal direction of the slit 111. When the brush 112 is disposed on the inner upper surface of the slit 111, when the flexible glass bonding substrate 10 is introduced into the container body 110, the flexible glass bonding substrate 10 can be slid into the container body 110 through the slit 111. Or impurities may be removed from the surface of the ultra-thin glass sheet 12 by contact with the brush 112. Therefore, it is convenient for the user since there is no need to intentionally remove the characters or impurities. In addition, when the flexible glass bonding substrate 10 is wound around the core portion 120, the upper surface of the flexible glass bonding substrate 10 can be prevented from being formed, that is, the ultra-thin glass sheet 12 of the surface of the flexible glass bonding substrate 10 can be prevented. Broken due to impurities. In this regard, the brush 112 may also be disposed on the inner lower surface of the slit 111. When the brush 112 is disposed on the inner lower surface of the slit 111, when the flexible glass bonding substrate 10 is introduced into the container body 110, the lower surface of the flexible glass bonding substrate 10 (based on the surface of the paper) can be prevented, that is, the base The surface of the base substrate 11 is in contact with the inner lower surface of the slit 111 to leave a mark. Further, the resistance is minimized, so that the operation of winding the flexible glass-bonding substrate 10 can be easily performed by a small amount of application.

The handle 113 connected to the rotating shaft of the core 120 can protrude from the two outer surfaces of the container body 110, so that the user can simply and easily rotate the core 120 from the outside of the container body 110. The handle 113 is steerable to rotate the core 120 in the direction in which it is wound in the front direction of the flexible glass-adhesive substrate 10 and in the direction behind the release of the flexible glass-adhesive substrate 10. Further, the handle 113 may have a foldable structure to avoid an increase in its volume. Therefore, when the storage container 100 is transported, the handle 113 can be folded over the outer surface of the container body 110. Further, when the flexible glass bonding substrate 10 is wound or unwound, the handle 113 can be horizontally unfolded so that the user can rotate the handle 113 by holding the handle 113 with the hand. At this time, since the user operates the rotation of the core portion 120 located in the container body 110 using the handle 113 from the outside of the container body 110, the user needs to visually recognize the rotation of the core portion 120 and/or the flexible glass-adhesive substrate. 10 is a state of being wound around the core 120 or released from the core 120. In this regard, the entire surface or upper surface of the container body 110 can be formed from a transparent material such that the interior of the container body 110 can be seen by a user. Further, the container body 110 may be configured such that one of its upper surfaces is partially or entirely open. After the operation of winding the flexible glass-adhesive substrate 10 on the core 120 using the handle 113 is completed, the handle 113 may unexpectedly rotate backward due to an external impact, so that the flexible glass-adhesive substrate 10 may be loosened. To prevent this, the handle 113 can provide a locking unit (not shown) that allows or stops the rotation of the handle 113, ie, the handle 113 is placed in a locked or unlocked position.

The core 120 is rotatably disposed in the container body 110. Since the core 120 is disposed in the container body 110, the flexible glass bonding substrate 10 wound around the core 120 is received in the container body 110, so that the flexible glass bonding substrate 10 completely prevents external dust or impurities from being contaminated. . Here, the core 120 is magnetically fixed to the proximal end 10a of the flexible glass-adhesive substrate 10 introduced into the container body 110 through the slit 111, so that when the core is rotated, the flexible glass-adhesive substrate 10 can be wound On the outer circumferential surface of the core. When the proximal end 10a of the flexible glass-adhesive substrate 10 is magnetically fixed to the core 120, the flexible glass-adhesive substrate 10 can be accommodated by winding or can be loosened in a reliable manner more easily and easily for use. . In addition, when the flexible glass bonding substrate 10 is wound or loosened, the amount of physical force applied to the flexible glass bonding substrate 10 can be minimized, thereby preventing the flexible glass bonding substrate 10 from being wound or loosened. Damaged during operation.

The core 120 according to the first embodiment includes a core body 121 and a magnetic unit 122. The core body is a columnar shape having a hollow internal space. The longitudinal ends of the core body 121 are rotatably coupled to the side walls of the container body 110. Further, the longitudinal ends of the core body 121 are connected to the handle 113 which is convex from the outer surface of the side walls of the container body 110. The hollow space formed in the core body 121 not only provides a space for providing the magnetic unit 122, but also allows the storage container 110 to be easily transported, that is, reduces the weight of the core 120. Preferably, the outer diameter of the core body 121 ranges from 400 mm to 800 mm. When the outer diameter of the core body 121 is less than 400 mm, the curvature of the flexible glass-bonding substrate 10 wound around the core body 121 is excessively large, so that the ultra-thin glass sheet 12 of the flexible glass-bonding substrate 10 may be during winding. rupture. When the outer diameter of the core body 121 exceeds 800 mm, the volume of the container body 110 accommodating the core body 121 is also enlarged by the same amount, so that the storage container 100 cannot pass through the door of a typical-sized office. In other words, if the outer diameter of the core body 121 is greater than 800 mm, it is inconvenient to use the flexible glass bonding substrate 10 as a sheet material because it is required to work before moving the flexible glass bonding substrate 10 into the workplace. The exterior of the site is released from the core body 121. Further, when the flexible glass bonding substrate 10 is manufactured indoors, it may be difficult to move the flexible glass bonding substrate 10 wound around the core body 121 to pass through the door.

The magnetic unit 122 is disposed on an inner circumferential surface of the core body 110 that extends in the longitudinal direction through the inner space of the core body 110. The magnetic unit 122 magnetically adsorbs the proximal end 10a of the flexible glass-adhesive substrate 10 such that the proximal end 10a adheres to the outer circumferential surface of the core body 110. The magnetic unit 122 can be implemented as a permanent magnet or an electromagnet. For example, when an electromagnet is provided as the magnetic unit 122, it can loosen the flexible glass-adhesive substrate 10 from the outer circumferential surface of the core body 110 by simply blocking the current supplied to the magnetic unit 122. The proximal end 10a of the flexible glass-adhesive substrate 10 magnetically fixed to the outer circumferential surface of the core body 110 can be unfolded without applying physical force, and the strength of the magnetic force can be adjusted. Therefore, it is possible to reduce the cost and reduce the weight of the magnetic unit 122.

When the magnetic unit 122 fixes the proximal end 10a of the flexible glass-adhesive substrate 10 in this way, the operation of winding or loosening the flexible glass-adhesive substrate 10 can be reliably performed.

When the flexible glass-adhesive substrate 10 is housed in the storage container 100 according to the first embodiment, the magnetic unit 122 is positioned close to the slit 111 by the rotary handle 113. Subsequently, an operation of holding the lateral sides of the flexible glass-bonding substrate 10 and then pushing the flexible glass-bonding substrate 10 through the slit 111 into the container body 110 is performed. When the flexible glass bonding substrate 10 is pushed inwardly by a certain length, the proximal end 10a of the flexible glass bonding substrate 10 formed of a magnetic material is adhered to the core body 121 by the magnetic force of the magnetic unit 122. Circumferential surface. At a position where the proximal end 10a of the flexible glass-adhesive substrate 10 is fixed to the outer circumferential surface of the core body 121, when the handle 113 is rotated forward, the core body 121 connected to the handle 113 is rotated forward. Thus, the flexible glass-adhesive substrate 10 having the proximal end 10a fixed to the outer circumferential surface of the core body 121 is wound around the outer circumferential surface of the core body 121. In this case, written on the surface of the ultra-thin glass sheet 12, the characters on the upper surface of the flexible glass-bonding substrate 10 or the impurities adhered to the surface of the ultra-thin glass sheet 12 are provided in the slit 111. The inner upper surface brush 112 is wiped or removed, and the flexible glass bonded substrate 10 is introduced into the core body 121 through the slit 111.

When the operation of winding the flexible glass bonding substrate 10 is completed, the locking unit (not shown) provided on the handle 113 is set to the locking position, thereby preventing the handle 113 from rotating backward or restricting the rotation of the handle. Therefore, the flexible glass-adhesive substrate 10 accommodated in the storage container 100 can be reliably stored or transported.

In the case of loosening the flexible glass-adhesive substrate 10 wound and accommodated in the storage container 100, the locking unit (not shown) is set to the unlocked position, and then the handle 113 is rotated backward. Next, the flexible glass bonding substrate 10 wound around the core portion 120 is drawn through the slit 111. Finally, when the flexible glass-adhesive substrate 10 is pushed out from the container body 110 by a slight force applied thereto, the proximal end 10a of the flexible glass-adhesive substrate 10 attracts the proximal end due to the magnetic force of the magnetic unit 122. The outer circumferential surface of the core body 121 of 10a is released. After the flexible glass-adhesive substrate 10 is simply and easily extracted from the storage container 100 in this manner, the flexible glass-adhesive substrate 10 can be used.

Hereinafter, a storage container according to a second exemplary embodiment of the present disclosure will be described with reference to FIGS. 3 to 5.

Fig. 3 is an exploded view depicting a storage container according to a second exemplary embodiment. Fig. 4 is a plan view showing a core portion shown in Fig. 3, and Fig. 5 is a cross-sectional view showing the storage container shown in Fig. 3.

As shown in FIGS. 3 to 5, the storage container 200 according to the second exemplary embodiment includes the container body 110 and the core 220.

The second exemplary embodiment is substantially the same as the first exemplary embodiment except for the structure of the core. The same component symbols will be used to denote the same components, and a detailed description thereof will be omitted.

The core 220 according to the second exemplary embodiment includes a core body 221 and a magnetic unit 222. The longitudinal ends of the core body 221 are rotatably coupled to the side walls from both sides of the container body 110, and are connected to the handle 113 which is convex from the outer surface of the side walls of the container body 110. The core body 221 includes a plurality of disks 223 and a plurality of connecting rods 225.

A plurality of discs 223 are erected to be perpendicular to the bottom surface of the container body 110 and spaced apart from each other in the longitudinal direction (i.e., parallel to the direction of the slits 111) such that the plurality of discs 223 face each other. In addition, a plurality of connecting rods 225 are disposed on the outer circumferential surface of the plurality of disks 223 and extend in the longitudinal direction of the core body 221 formed by the plurality of disks 223 spaced apart from each other, thereby connecting a plurality of circles Disk 223. As shown in FIGS. 3 to 5, the plurality of connecting rods 225 may include a set of connecting rods disposed on the top, bottom, left side, and right side of the plurality of discs 223, each connecting rod set being composed of two or more connecting rods. 225 composition. To this end, each of the plurality of disks 223 has a fitting recess on the outer circumferential surface, and its depth corresponds to the thickness of the connecting rod 225. Each of the connecting rods 225 is fitted into a fitting recess corresponding to the plurality of disks 223. Since the connecting rod 225 is fitted to the fitting recess, and the depth of the fitting recess corresponds to the thickness of the connecting rod 225, the outer circumferential surface of the disc 223 and the surface of the connecting rod 225 can be coplanar without any height difference, and thus The wound glass surface provided by the flexural glass bonding substrate 10 corresponds to the winding surface of the cylindrical core body (121 in Fig. 1) according to the first exemplary embodiment. In order to minimize the weight, the core body 221 is formed by a plurality of discs 223 and a plurality of connecting rods 225, whereby the storage container 200 can be transported more easily. According to the second exemplary embodiment, each of the plurality of disks 223 has at least one through hole 224 formed through the disk to further reduce the weight of the core body 221 and the weight of the storage container 200. The size of the aperture 224 can be maximized while maintaining the strength of the disk 223. Although each aperture 224 may have a fan shape as shown in FIG. 3, it is merely illustrative. The holes 224 may have various shapes such as a hook shape, a cross shape, and the like, and the number of holes is not limited.

The magnetic unit 222 is disposed on one or more of the plurality of connecting rods 225. According to the second exemplary embodiment, the magnetic unit 222 is disposed on a set of connecting rods 225 on one side of the disk 223. Although the number of the connecting rods 225 on which the magnetic unit 222 is disposed is not limited, preferably, the magnetic unit 222 is disposed on the connecting rod 225 of the plurality of connecting rods 225 disposed adjacent to each other. The magnetic unit 222 disposed on the connecting rods 225 adjacent to each other has the effect of being close to the flexible glass bonding substrate 10 in the case where the flexible glass bonding substrate 10 is to be wound around the core 220. The first magnetic unit 222 of the end 10a cannot fix the proximal end 10a of the flexible glass-adhesive substrate 10 to its surface by magnetically attracting the proximal end 10a, and the subsequent second magnetic unit or third magnetic unit 222 can be immediately fixed and flexible. The glass is bonded to the proximal end 10a of the substrate 10. As described above, when the magnetic unit 222 is disposed on the connecting rods 225 adjacent to each other, the reliability and efficiency of the operation of accommodating the flexible glass bonded substrate 10 in the storage container 220 can be improved.

Further, each of the connecting rods 225 has a plurality of fitting recesses disposed in the longitudinal direction, and the depth of the fitting recesses corresponds to the thickness of the magnetic unit 222. Therefore, one surface of each magnet unit 222 is exposed to the outside. Since the proximal end 10a of the flexible glass-bonding substrate 10 is directly held by the exposed surface of the magnet unit 222, the proximal end 10a of the flexible glass-adhesive substrate 10 can be more reliably and safely fixed, and then the core body 221 The flexible glass bonded substrate 10 is wound around. According to the second exemplary embodiment, the connecting rod 225 is fitted to the fitting recess formed on the outer circumferential surface of the disc 223, the depth of which corresponds to the thickness of the connecting rod 225, and the magnetic unit 222 is fitted to the connecting rod 225. The mounting recess of the surface has a depth corresponding to the thickness of the magnetic unit 222. Therefore, the outer circumferential surface of the disk 223, the outer surface of the connecting rod 225, and the outer surface of the magnetic unit 222 form a smooth curled surface without any level difference, thereby preventing the flexible when the flexible glass bonded substrate 10 is wound. Damage or deformation of the glass bonded substrate 10.

Hereinafter, a storage container according to a third exemplary embodiment of the present disclosure will be described with reference to FIG.

Fig. 6 is a cross-sectional view depicting a storage container according to a third exemplary embodiment.

As shown in FIG. 6, the storage container 300 includes a container body 110, a core 220, and a guiding portion 311.

The third exemplary embodiment is substantially the same as the second exemplary embodiment except that the guide portion is added. The same component symbols will be used to denote the same components, and a detailed description thereof will be omitted.

The guiding portion 311 according to the third exemplary embodiment is disposed at the bottom of the container body 110. The guiding portion 311 guides the proximal end 10a of the flexible glass-bonding substrate 10 introduced into the container body 110 through the slit 111 toward the core 220, more specifically toward the magnetic unit 222, such that the proximal end of the flexible glass-bonding substrate 10 10a can be easily fixed by the magnetic unit 222. In this regard, the guiding portion 311 includes an inclined surface 312 that is inclined upward toward the magnetic unit 222 of the core 220 in the direction in which the flexible glass bonding substrate 10 is introduced. The inclined surface 312 may be the surface of the block, and the cross section of the block is triangular, but is not intended to be limited thereto.

According to the third exemplary embodiment, along the inclined plane of the guiding portion 311 provided at the bottom of the container body 110, the proximal end 10a of the flexible glass-adhesive substrate 10 introduced into the container body 110 can be disposed along The inclined surface of the guiding portion 311 on the bottom of the container body 110 is guided to the magnetic unit 222 of the core 220, whereby the flexible glass bonding substrate 10 can be magnetically fixed to the magnetic unit 222 in a more reliable manner. Further, the guide portion 311 provided at the bottom of the container body 110 can reduce the volume of the core portion 220 by the volume equal to the volume of the guide portion 311, and thus reduce the weight of the core portion 220, thereby making it easier to transport and store. Container 300. Referring to Fig. 6, the inclined surface 312 has a height at which the proximal end 10a of the flexible glass-bonding substrate 10 can be directly fixed to the magnetic unit 222, but this is only for the purpose of clearly illustrating the flexible glass by the inclined surface 312. The proximal end 10a of the bonded substrate 10 is directed to the magnetic unit 222. In essence, the inclined surface 312 must have a height such that the proximal end 10a of the flexible glass bonded substrate 10 can be directed to reach the magnetic region of the magnetic unit 222. That is, even in the case where the flexible glass bonding substrate 10 is guided to the top of the inclined surface 312, a gap needs to be maintained between the flexible glass bonding substrate 10 and the magnetic unit 222, so that when the volume of the core portion 220 is followed, When the flexural glass bonding substrate 10 is wound around the core portion 220 and increased, the inclined surface 312 does not interfere with the flexible glass bonding substrate 10.

As shown in FIG. 7, the storage container 400 according to the fourth exemplary embodiment includes a container body 110, a core 220, and a guiding portion 411.

The fourth exemplary embodiment is substantially the same as the second exemplary embodiment except that the guide portion is added. The same component symbols will be used to denote the same components, and a detailed description thereof will be omitted.

The guiding portion 411 according to the fourth exemplary embodiment is disposed at the bottom of the container body 110. The guiding portion 411 performs a guiding function such that the proximal end 10a of the flexible glass-adhesive substrate 10 introduced into the container body 110 through the slit 111 is directed toward the magnetic unit 222 of the core 220. In this manner, the guide portion 411 facilitates securing the proximal end 10a of the flexible glass bonded substrate 10 to the magnetic unit 222. In this regard, the guide portion 411 includes an inclined surface 412, a horizontal surface 413, and a drum 415. The inclined surface 412 is inclined upward toward the magnetic unit 222 of the core 220 in the direction in which the flexible glass bonded substrate 10 is introduced. The horizontal surface 413 extends from the inclined surface 412 to be formed below the core 220. In the case where the flexible glass bonded substrate 10 is wound around the core portion 220, the magnetic unit 222 of the core portion 220 is positioned above the horizontal surface 413. At least one roller 415 can be disposed on the horizontal surface 413. The roller 415 is in rolling contact with the lower surface of the flexible glass-bonding substrate 10 introduced into the container body 110, that is, the surface of the base substrate (11 of FIG. 2). Here, the drum 415 is elastically supported in the up and down direction (based on the paper sheets of Figs. 7 to 9) by an elastic member (not shown) connected to the drum 415, such as a spring. According to the fourth exemplary embodiment, in the storage container 400, the proximal end 10a of the flexible glass-adhesive substrate 10 having various thicknesses can be guided to the magnetic body of the core 220 by the roller 415 elastically supported in the upper and lower directions on the horizontal surface 413. Unit 222. Referring to Figure 7, the roller 415 has a height at which the proximal end 10a of the flexible glass bonded substrate 10 can be directly fixed to the magnetic unit 222, but this is only for the purpose of clearly illustrating the flexible glass bonded substrate by the roller 415. The proximal end 10a of 10 is directed toward the magnetic unit 222. In essence, the roller 415 must have a height such that the proximal end 10a of the flexible glass bonded substrate 10 can be directed to reach the magnetic region of the magnetic unit 222. With this configuration, when the volume of the core portion 220 increases as the flexible glass-adhesive substrate 10 is wound around the core portion 220, the roller 415 does not interfere with the flexible glass-adhesive substrate 10.

Figures 8 and 9 are cross-sectional views schematically depicting the upward and downward movement of the drum 415 according to the thickness of the flexible glass bonded substrate. When the flexible glass-adhesive substrate 10 having a thickness d2 (FIG. 9) having a thickness larger than that of the flexible glass-adhesive substrate 10 (Fig. 8) is in rolling contact with the drum 415, the drum 415 is moved downward. In this position, when the flexible glass-adhesive substrate 10 having the thickness d1 is in rolling contact with the roller 415, the roller 415 is moved upward, thereby guiding the proximal end 10a of the flexible glass-adhesive substrate 10 toward the magnetic unit 222. The upward and downward movement of the drum 415 shown in Figs. 8 and 9 is shown to indicate only that the roller 415 is in a flexible manner during the rolling contact of the flexible glass bonded substrate 10 having different thicknesses with the drum 415. The relative movement of the different thicknesses of the glass bonded substrate 10. That is, the drum 415 is initially maintained at the position moved to the highest position. When the flexible glass-bonding substrate 10 having various thicknesses is in rolling contact with the roller 415, the roller 415 is moved downward by an amount corresponding to the amount of pressure applied thereto, thereby providing the flexible glass-bonding substrate 10 having various thicknesses. The proximal end 10a is directed toward the magnetic unit 222 such that the proximal end 10a can be more easily attracted by the magnetic force of the magnetic unit 122.
