FIG. 5 is a schematic external view for explaining a relief area provided in the storage box according to the present invention. The embodiments described here are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise described, the present invention is not limited to these embodiments.

  FIG. 1 is an external view showing an embodiment of a storage box according to the present invention. The storage box 30 according to the present invention has a substantially rectangular parallelepiped box portion 10 having an opening on the front surface, and a substantially rectangular parallelepiped drawer portion 20 having an open top surface that can be stored in the box portion 10. Then, the storage box 30 slides and pulls out the drawer portion 20 accommodated in the box portion 10 from the opening portion of the box portion 10, and takes out and puts in articles from the opened upper surface of the drawer portion 20, and then pulls out again. The article 20 is accommodated by sliding the part 20 into the box part 10. In addition, it is preferable to provide a handle portion 22 on the front surface of the drawer portion 20 so that the box portion 10 can be easily taken in and out. In addition, one or two pairs of wheels 24 may be provided on the bottom surface of the drawer portion 20 so that the drawer portion 20 can be taken in and out more easily. The material of the drawer 20 is preferably a synthetic resin, but is not particularly limited and may be cardboard (paper) or wood.

  The box portion 10 constituting the storage box 30 includes a cardboard box main body 12, a bag-shaped exterior sheet 14 that covers the outer surface of the box main body 12, and the box main body 12 along the opening of the box portion 10. And a mouth frame portion 16 provided at the front end portion. The cardboard used for the box body 12 is not particularly limited, but it is preferable to use an A flute having a corrugated core and a thickness of about 5 mm. However, depending on the shape and use of the storage box 30, cardboard such as B flute, W flute, and E flute may be used. Moreover, as a material of the mouth frame part 16, use of a synthetic resin is preferable.

  The exterior sheet 14 is pre-sewn into a substantially rectangular parallelepiped bag shape having substantially the same external dimensions as or slightly smaller than the box body 12, and the opening of the bag-shaped exterior sheet 14 and the box body 12 are sewn. It is installed so that the outer surface of the box main body 12 may be covered while aligning with the opening. The exterior sheet 14 and the box body 12 are bonded to each other in the vicinity of the front end portion of the box body 12, that is, the region where the mouth frame portion 16 is installed, or the vicinity thereof. The exterior sheet 14 and the box body 12 are preferably bonded only in the above-described region and not bonded in the other region. However, in addition to the above region, an adhesive region is provided on a part of the outer surface of the box body 12. The sheet 14 may be prevented from being displaced.

  As the exterior sheet 14, vinyl leather is preferably used, but other synthetic resin sheets, synthetic leather, cotton cloth, synthetic fiber cloth, linen cloth, silk, denim, canvas, lace, satin, suede, Japanese woven fabric, Western woven fabric. There is no particular limitation as long as it is in the form of a cloth, such as a faux fur cloth that has been brushed, or a lame knit in which a metal disk is sewn. Further, the color and pattern are not particularly limited, and may be any single color, wood grain, animal pattern, brick tone, camouflage pattern, or the like. Furthermore, the surface of the exterior sheet 14 can be embossed. Further, the exterior sheet 14 is preferably subjected to water repellent treatment, and the exterior sheet 14 has a function of protecting the box body 12 from moisture from the outside by this water repellent treatment, maintaining strength as a cardboard and preventing deformation. Also have. The water repellent treatment may be performed on the surface of the box body 12 instead of the exterior sheet 14. Further, the water repellent treatment is not necessarily performed.

  Next, the manufacturing method of the box part 10 is demonstrated easily using FIG. First, as shown in FIG. 2 (a), a bag-shaped exterior sheet 14 that is previously sewn into a shape that is the same as or slightly smaller than the outer dimensions of the box body 12 is prepared.

  Next, the cardboard member cut into a predetermined shape to be the box body 12 is inserted into the exterior sheet 14 while being folded. Next, as shown in FIG. 2B, after the cardboard member is developed in the exterior sheet 14, a predetermined portion is fixed with an adhesive tape or the like to form the box body 12. At this time, since the exterior sheet 14 has the same or slightly smaller outer dimensions than the box body 12, the exterior sheet 14 and the box body 12 are appropriately deformed. It will be covered in a moderately stretched state. And the exterior sheet | seat 14 and the box main body 12 are adhere | attached with adhesive members, such as a double-sided tape provided in the outer surface of the front-end part (area | region near opening part) of the box main body 12, with this state. Therefore, the exterior sheet 14 does not suffer from appearance defects such as wrinkles and slack that are generated when the entire surface of the box body 12 is bonded as in the conventional case.

  Further, the storage box 30 according to the present invention uses a small amount of an adhesive member for mainly bonding the exterior sheet 14 and the box body 12 at the front end portion of the box body 12, and also allows the use of double-sided tape. Therefore, adverse effects on the human body due to short-term and long-term volatilization of chemical substances contained in the adhesive can be suppressed. The width of the adhesion region is preferably 10 mm to 50 mm from the front end of the box body 12, and particularly preferably around 30 mm.

  Finally, as shown in FIG. 2C, the box part 10 constituting the storage box 30 is manufactured by bonding the mouth frame part 16 to the front end part of the box body 12 covered with the exterior sheet 14. . At this time, it is preferable to use a double-sided tape for bonding the mouth frame 16. In addition, since the exterior sheet 14 is sewn in a bag shape in advance, peeling from the cut portion that occurs when the exterior sheet is cut and bonded to the box body 12 as in the past does not occur. Further, by forming the mouth frame portion 16 in the opening portion which is the only cutting portion in the exterior sheet 14, the mouth frame portion 16 also has a function of preventing the exterior sheet 14 from being peeled off from the box body 12. Become.

  Further, as shown in FIG. 3A, the storage box 30 according to the present invention is provided with a mouth frame portion 16 having an inner circumference smaller than the inner circumference of the opening portion of the box body 12. A step d having a predetermined dimension may be formed on the bottom inner surface of the part and the bottom inner surface of the mouth frame 16. And this level | step difference d plays the role of the stopper which prevents the drawer | drawing-out part 20 from dropping out, when the storage box 30 inclines. Therefore, even if the storage box 30 is tilted toward the mouth frame 16 due to an earthquake, carrying, children's mischief, or some external factor, this step d functions as a stopper and the pull-out portion 20 falls off to some extent. Can be prevented. When the drawer 20 is pulled out, as shown in FIG. 3 (b), the drawer 20 can be easily pulled out by lifting the drawer 20 upward and overcoming the step d.

  Here, the result of measuring the limit force (load) at which the value of the step d is changed and the step d functions as a stopper is shown in FIG. From FIG. 4, it can be seen that if the value of the level difference d is 1.29 mm or more, the level difference d functions as a stopper of the extraction portion 20 up to a force of 7.8 kgf. Therefore, if the value of the level difference d is 1.29 mm or more, preferably around 1.6 mm, depending on the size of the storage box 30 and the article to be stored, the drawer portion 20 is inclined to a considerable inclination with respect to the storage box 30. It is possible to prevent omission. In addition, it is preferable that the upper limit of the level | step difference d shall be 2 mm-3 mm from a practical viewpoint.

  Further, on the inner surface of the back side of the box body 12 of the storage box 30 according to the present invention, as shown in FIG. 5, a part of the folded portion of the cardboard member forming the back side surface of the box body 12 is cut off, The escape area 18 may be formed. 5 is a schematic external view in which a part of the upper surface of the box portion 10 is cut away.

  Here, in the conventional storage box, when the drawer part 20 is suddenly inserted into the box part 10, the air inside the box part 10 is instantaneously compressed and its internal pressure increases. It is difficult to accommodate in the box part 10. However, by forming the relief area 18, the air inside the box portion 10 can enter and leave the space between the liner and the core of the cardboard member forming the box body 12 via the relief area 18. Thereby, even if the drawer part 20 is suddenly inserted into the box part 10, the air inside the box part 10 can enter the space between the liner and the core of the cardboard member by the escape area 18. As a result, the compression rate of the air inside the box portion 10 decreases and the increase in internal pressure also decreases, so that the drawer portion 20 can be completely accommodated in the box portion 10 instantaneously. Moreover, since the inside of the box part 10 and the space in the corrugated cardboard of the box main body 12 are connected by the escape area 18, the gas flow area increases and a dehumidifying effect on the inside of the box part 10 can be expected. The relief area 18 is preferably formed so that the corrugated cardboard member is easily folded back and does not impair the aesthetic appearance.

  From the above, the storage box 30 according to the present invention covers the box body 12 with the bag-shaped exterior sheet 14 and further bonds the exterior sheet 14 and the box body 12 in a region near the opening of the box body 12. In addition, there is no appearance defect such as wrinkles or slack in the exterior sheet 14. For example, if the exterior sheet 14 is made of synthetic leather, the storage box 30 uses a cheap and light cardboard member, but the appearance is a high-quality storage box 30 having a leather texture. Further, by increasing variations of the exterior sheet 14 to be used, it is possible to provide various storage boxes 30 having an appearance that matches the user's personality and the interior of the room.

  Furthermore, since the storage box 30 is made of cardboard, it is lightweight and easy to carry, and in addition to being free from sharp debris when broken, it can be disposed of relatively easily.

  In this example, the drawer 20 has been described as an example of a single-stage storage box. However, in the present invention, the drawer 20 has two, three, or more drawers in the vertical direction. And it is applicable also to the storage box which has the some drawer | drawing-out part 20 in the vertical direction. In addition, there is no particular limitation on the external dimensions of the storage box, such as a storage box for clothing that suits the size of the home, and a storage box of comics, magazines, CDs, MDs, DVDs, magnetic video tapes, and other dimensions. In addition, the present invention can be applied to the present invention, and the present invention can be modified and implemented without departing from the gist of the present invention.

It is an external view of the storage box which concerns on this invention. It is a figure explaining the outline of the manufacturing method of the storage box concerning the present invention. It is a schematic cross section explaining the level | step difference provided in the storage box which concerns on this invention. It is a graph which shows the relationship between the value of a level | step difference, and the limit force in which the level | step difference functions as a stopper. It is a typical external view for demonstrating the relief area | region provided in the storage box which concerns on this invention.
