Description

  TECHNICAL FIELD The present invention relates to a sheet-like material storage box and a sheet-like material storage box, and in particular, a sheet-like material storage box and a sheet-like material containing a sheet-like material folded by a pop-up method and having relatively large surface friction. Concerning the containment box.

  Kitchen paper is widely used around kitchens for wiping off moisture and oil, and as a substitute for drop lids. Kitchen paper is a roll of long paper with perforations and other cut lines at appropriate intervals, or a sheet (sheet-like material) cut into a size suitable for use in advance. Some of these are alternately stacked and housed in a rectangular parallelepiped box. As a box for storing a stack of bi-fold sheets, a top surface portion having a take-out port for taking out stored items, a bottom surface portion facing the top surface portion, a pair of side surfaces facing each other, and There is a storage box having a pair of side surface flap portions projecting from both lateral edges and a pair of upper and lower flap portions projecting from both lateral end edges of the upper surface portion and the bottom surface portion (see, for example, Patent Document 1).

Japanese Patent No. 4680525 (paragraph 0013, FIG. 6 etc.)

  When the sheet-like kitchen paper is completely contained in the inside of the storage box, the fingertip is usually inserted from the outlet and the kitchen paper is picked up. Kitchen paper is generally harder and more lumpy than tissue paper, so a small outlet such as that formed in a tissue paper box can pick the center of the kitchen paper surface within the reach of your fingertip. It is difficult to form a wide outlet so that the end of the kitchen paper can be picked. However, kitchen paper generally has a larger surface friction than tissue paper, so if the outlet is widened, the second kitchen paper may come out of the storage box when pulling out the surface kitchen paper. there were.

  In view of the above-described problems, an object of the present invention is to provide a sheet-like material storage box and a sheet-like material containing box that can take out sheet-like materials with relatively large surface friction one by one.

  In order to achieve the above object, the sheet-like material storage box according to the first aspect of the present invention is a sheet-like material group in which, for example, as shown in FIG. It is a sheet-like object storage box 10 that accommodates Sg (see, for example, FIG. 2 (B)), and includes an outlet forming plate 11 in which an outlet 10h from which the sheet S is taken out is formed; When the sheet-like material group Sg (for example, see FIG. 2B) is accommodated in the sheet-like material storage box 10, a standard adult fist is taken into the sheet-like material storage box 10 from the outlet 10h. The sheet Se is formed in a size that allows the end Se of the sheet S to be picked, and a narrow portion 10 hn narrower than the width Ls of the sheet S to be picked is formed.

  With this configuration, when the sheet-like material group is accommodated in the sheet-like material storage box, even if the second sheet-like material comes out continuously when the sheet material on the surface layer is pulled out, the width is narrow. The sheet-like material on the surface layer can be separated from the second sheet-like material by the resistance when passing through the section.

  In addition, the sheet-like material storage box according to the second aspect of the present invention is, for example, as shown in FIG. 1, in the sheet-like material storage box 10 according to the first aspect of the present invention described above, Of the boundary line between the outlet forming plate 11 and the outlet 10h, a basic shape is formed in a rectangular shape by a pair of width boundary lines 11b and a pair of front and rear boundary lines 11c orthogonal to the pair of width boundary lines 11b. At the same time, the distance Db between the pair of width boundary lines 11b is set to the width Ls of the sheet-like material S picked up when the sheet-like material group Sg (see, for example, FIG. 2B) is accommodated in the sheet-like material accommodation box 10. In contrast, the narrow width portion 10hn is formed by forming a protruding portion 11p protruding inside the outlet 10h at the center of the width boundary line 11b. Here, the rectangle is a quadrilateral in which all four inner angles are right angles, and is a square or a rectangle having a long side and a short side.

  If comprised in this way, when a sheet-like material group will be accommodated in a sheet-like material storage box and a sheet-like material will be pulled out, resistance will become small and it will become easy to pull out.

  In addition, the sheet-like object storage box according to the third aspect of the present invention is, for example, as shown in FIG. 1, in the sheet-like object storage box 10 according to the second aspect of the present invention, the outlet forming plate 11 is The lid portion 11f is openable and closable connected to the front / rear boundary line 11c and covers the outlet 10h.

  If comprised in this way, it can prevent that a foreign material penetrate | invades in a sheet-like object storage box by closing a cover part.

  Moreover, the sheet-like material storage box according to the fourth aspect of the present invention is, for example, as shown in FIG. 1, in the sheet-like material storage box 10 according to the third aspect of the present invention, the lid portion 11f is a pair. Each of the front and rear boundary lines 11c is connected to each other; the pair of lid portions 11f is formed with a corrugated opposing side 11a that is a side facing each front and rear boundary line 11c. The opposing sides 11a are configured to fit together when closed.

  With this configuration, when the sheet-like material group is accommodated in the sheet-like material storage box and the sheet-like material is pulled out, the pop-up sheet-like material is hooked on a pair of opposite sides, and the sheet-like material is the sheet. It can suppress falling into a shape accommodation.

  Moreover, the sheet-like material storage box according to the fifth aspect of the present invention includes a lid in the sheet-like material storage box 10 according to the third aspect or the fourth aspect of the present invention as shown in FIG. The portion 11f is connected to the front / rear boundary line 11c via a cut line Cc that can be cut.

  If comprised in this way, when a cover part is unnecessary, a cover part can be easily removed.

  In addition, the sheet-like material storage box according to the sixth aspect of the present invention relates to any one of the third to fifth aspects of the present invention, as shown in FIGS. 1 and 4, for example. In the sheet-like material storage box 10, the sheet-like material storage box 10 is formed in a rectangular parallelepiped shape; The stoppers 11s and 15s (see FIG. 4) projecting into the interior of the housing 11 and include stoppers 11s and 15s that suppress the closed lid portion 11f.

  If comprised in this way, it can prevent that the closed cover part opens halfway.

  In addition, the sheet-containing container according to the seventh aspect of the present invention is a sheet-like object according to any one of the first to sixth aspects of the present invention as shown in FIG. A storage box 10; and a sheet group Sg (see, for example, FIG. 2B) stored in the sheet storage box 10.

  According to this configuration, even when the second sheet-like material comes out continuously when the surface-layer sheet material is pulled out, the second sheet-like material is removed by the resistance when passing through the narrow portion. It can be pulled away from the sheet.

  According to the present invention, when the sheet-like material group is accommodated in the sheet-like material storage box, the second sheet-like material may come out continuously when the sheet material on the surface layer is pulled out. The sheet-like material on the surface layer can be separated from the second sheet-like material by the resistance when passing through the section.

(A) is a fragmentary perspective view of the storage box which concerns on the modification of embodiment of this invention, (B) is a fragmentary sectional view of the storage box which concerns on the modification of embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or similar members are denoted by the same or similar reference numerals, and redundant description is omitted.

  First, referring to FIG. 1, a storage box 10 as a sheet-like material storage box according to an embodiment of the present invention and a paper-containing storage box 1 as a sheet-like material storage box according to an embodiment of the present invention will be described. To do. 1A is a perspective view of the storage box 10, and FIG. 1B is a plan view of the storage box 1 with paper. For convenience of explanation, FIG. 1B shows a state in which a flap 11f as a lid is opened. The paper-containing storage box 1 is a storage box 10 in which kitchen paper (hereinafter simply referred to as “paper”) S as a sheet-like material is stored.

  FIG. 2 shows the paper S stored in the storage box 10. 2A is a perspective view of one paper S, and FIG. 2B is a side view of the stacked paper S. FIG. In this embodiment, the paper S is of a non-woven fabric type using natural pulp. A web is formed by an airlaid method, and fibers of the web are bonded by a chemical bond method using a spray. The web is obtained by laminating fibers and spreading them in a sheet shape. The airlaid method is a method in which defibrated pulp, short fibers, or a mixture thereof is stirred with a rotor and discharged from a screen opening to form a web. The chemical bond method using a spray is a method in which a binder (adhesive) is sprayed on a web and dried to bond fibers. Further, the paper S of the present embodiment is embossed with an embossing roll after the fibers of the web are joined. The paper S is thicker than the tissue paper and has a rough surface. The paper S has a relatively large surface friction due to surface fluffing, embossing, and the like. Here, the relatively large friction means that two sheets of paper S are placed on a horizontal surface with a smooth surface, and when the upper paper S is moved horizontally, the lower paper S is continuous. It is a friction that moves.

  The paper S formed as described above is formed in a rectangular shape. The paper S is folded in two along a fold line Sc that connects the midpoints of a pair of opposing sides Ss. The paper width Ls, which is the width of the paper S, is equal to the length of the folding line Sc. That is, the folded paper Sc is provided so that the depth direction of the folded paper S is halved so that the width does not change. Regarding the paper S, for convenience of explanation, one side is referred to as a half surface Sa and the other side is referred to as a remaining surface Sb with the folding line Sc as a boundary. The paper S sandwiches the half surface Sa of another paper S2 between the half surface Sa and the remaining surface Sb of a certain paper S1, and the above-mentioned one paper S1 between the half surface Sa and the remaining surface Sb of the other paper S2. Is stored in the storage box 10 as a paper group Sg that is stacked so as to sandwich the half surface alternately so as to sandwich the remaining surface Sb and the half surface Sa of another paper S3. At this time, the size of the storage box 10 is determined so that a slight gap is generated around the paper group Sg. In the paper group Sg, the end Se of the uppermost paper S1 does not overlap the fold line Sc of the second paper S2, and the half surface Sa slightly inside the fold line Sc of the second paper S2. It is located above (see also FIG. 1B). The paper group Sg formed by stacking the papers S in this way is the second sheet when the paper S1 is separated from the second paper S2 when the half surface Sa of the uppermost paper S1 is picked and pulled up. The half surface Sa of the paper S2 can be in a protruding state. Such a method of folding the paper S is called a pop-up method.

  Returning to FIG. 1 again, the configuration of the storage box 10 will be described. The basic shape of the storage box 10 is a rectangular parallelepiped. The storage box 10 includes a top plate 11 as an outlet forming plate, a front plate 12, a bottom plate 13, a rear plate 14, and a pair of side plates 15 as side plates. In the present embodiment, the top plate 11 is formed in a rectangular shape that is slightly larger than the half surface Sa (see FIG. 2A). The bottom plate 13 faces the top plate 11 and is formed in the same size as the top plate 11. The front plate 12 is orthogonal to the top plate 11 and the bottom plate 13. The rear plate 14 faces the front plate 12 and is orthogonal to the top plate 11 and the bottom plate 13. The pair of side plates 15 are orthogonal to the top plate 11, the front plate 12, the bottom plate 13, and the rear plate 14, respectively.

  The top plate 11 has a flap 11f as a lid. The top plate 11 is configured such that the outlet 10h appears by opening the flap 11f. As shown in FIG. 1 (B), the outlet 10h has a rectangular basic shape. The basic shape of a rectangle may not be a rectangle if you pay close attention to the details, but it includes a shape that can be recognized as a rectangle as a whole, in other words, it is a rectangle as a whole, This means that there are protrusions and chamfers. In FIG. 1B, the flap 11f is omitted for convenience of explanation. The outlet 10h is formed inside the outer edge of the top plate 11 so that the top plate 11 remains on the entire outer periphery. In the outlet 10h, a pair of width boundary lines 11b facing each other and a pair of front and rear boundary lines 11c facing each other are orthogonal to each other to form an overall contour. The corner where the width boundary line 11b and the front / rear boundary line 11c meet is formed in a quadrant. In the paper group Sg stored in the storage box 10, the direction in which the fold line Sc extends is the same as the direction in which the front / rear boundary line 11c extends.

  The interval between the pair of width boundary lines 11b (hereinafter referred to as “width interval Db”) is substantially the same as the paper width Ls. Here, the width interval Db is substantially the same as the paper width Ls. The difference between the width interval Db and the paper width Ls is in the range of ± 3%. In addition, a protrusion 11p protruding in a direction approaching each other is formed at the center of each width boundary line 11b. Each projection 11p protrudes in an arc shape toward the inside of the outlet 10h on the same surface as the top plate 11. The width interval Db is narrower than the paper width Ls in the portion where the protrusion 11p exists. The width of the outlet 10h where the protrusion 11p is formed is referred to as a narrow portion 10hn. The interval between the narrow width portions 10hn is preferably 90% to 97% of the paper width Ls, and is 95% of the paper width Ls in the present embodiment.

  The distance between the pair of front and rear boundary lines 11c is shorter than the distance between the opposing folding lines Sc of the paper group Sg. In the present embodiment, the interval between the pair of front and rear boundary lines 11c is determined so that the folding line Sc of the paper S at the top of the paper group Sg is not visible from the outlet 10h and the end Se is visible from the outlet 10h. It has been. In the present embodiment, the length of the width boundary line 11b is shorter than the length of the front / rear boundary line 11c. The outlet 10h formed as described above is formed in a size that allows at least a standard adult fist to be taken in and out, and is formed in a size of about 220 mm × 120 mm in the present embodiment. . The fist of “size that can be put in and out of the fist” described here is merely used as a reference for the size of the outlet 10h, and does not necessarily require that the fist be actually put in and out. Absent. That is, a size that allows the paper S to be picked by putting a hand into the storage box 10 from the outlet 10h is determined.

  The flaps 11f are composed of a pair connected to the front and rear boundary lines 11c. The flap 11f is formed integrally with the top plate 11 before opening. The pair of flaps 11f before opening is connected at the opposite side 11a. The facing side 11a is a side of the flap 11f that faces the front-rear boundary line 11c. The opposing side 11a is formed in a waveform in the present embodiment. The waveform of the opposite side 11a in the present embodiment is such that when viewed from one side, one mountain and two valleys sandwiching this mountain (two peaks and one valley when viewed from the other side) appear. Is formed. In the present embodiment, the distance between the top of the corrugated mountain and the bottom of the valley of the opposing side 11a is approximately 10 mm.

  The storage box 10 is configured such that a flap 11f is formed by cutting the top plate 11 before opening at the opposite side 11a and the width boundary line 11b and bending it along the front-rear boundary line 11c. That is, the portion of the top plate 11 surrounded by the opposite side 11a, the pair of width boundary lines 11b, and the front and rear boundary lines 11c becomes the flap 11f. The flap 11f is configured to be opened and closed with the front / rear boundary line 11c as an axis. The storage box 10 is configured such that an opening 10h through which the stored paper S is taken out is formed by opening the flap 11f. In the present embodiment, as described above, a pair of flaps 11f connected to the front and rear boundary lines 11c is formed. With such a configuration, it is possible to enlarge the outlet 10h while suppressing the height when the flap 11f is opened. By forming the take-out port 10h large, it is easy to put the hand into the storage box 10 and take out the stored paper S. The storage box 10 is formed by processing board paper (typically coated cardboard) having a thickness of about 0.45 to 0.70 mm. For this reason, the storage box 10 has elasticity. The storage box 10 is typically formed integrally by cutting and assembling a single paperboard.

  In FIG. 3, the expanded view of the storage box 10 is shown. As shown in FIG. 3, the rear plate 14, the top plate 11, the front plate 12, and the bottom plate 13 are connected in this order in the direction in which the width boundary line 11 b extends (hereinafter referred to as “short side direction Ds”). . The pair of side plates 15 are connected to both ends of the top plate 11 in the direction in which the front / rear boundary line 11 c extends (hereinafter referred to as “long side direction Dt”). A rear plate overlap margin 14c is connected to the rear plate 14 at both ends in the long side direction Dt. A front plate overlap margin 12c is connected to the front plate 12 at both ends in the long side direction Dt. A bottom plate overlap margin 13c is connected to the bottom plate 13 at both ends in the long side direction Dt. The bottom plate 13 is connected to a connecting piece 13d that overlaps the rear plate 14 on the side opposite to the side to which the front plate 12 is connected. In the unfolded state before the assembly box 10 is assembled, the opposing side 11a and the width boundary line 11b are typically formed by perforations and are not cut as a whole. Here, the perforation is a line cut in a dotted line shape.

  When assembled from the unfolded state shown in FIG. 3 to the storage box 10 shown in FIG. 1A, the rear plate 14, the top plate 11, the front plate 12, the bottom plate 13, and the connection piece 13d extend in the long side direction Dt. The connecting piece 13d is bent at the boundary line and bonded to the back surface of the rear plate 14 (the surface that is the inside of the storage box 10), thereby forming a rectangular tube shape. Further, the side plate 15, the rear plate overlap allowance 14 c, the front plate overlap allowance 12 c, and the bottom plate overlap allowance 13 c are bent at a boundary line extending in the short side direction Ds. The front plate overlap allowance 12c and the rear plate overlap allowance 14c are formed in sizes that do not interfere with each other when bent with respect to the front plate 12 and the rear plate 14, respectively. The bottom plate overlap allowance 13c is formed in a size that overlaps both the front plate overlap allowance 12c and the rear plate overlap allowance 14c when bent with respect to the bottom plate 13. At both ends of the rectangular tube, first, the front plate overlap margin 12c and the rear plate overlap allowance 14c are bent, the bent bottom plate overlap allowance 13c is overlapped thereon, and the side plate 15 is further overlapped thereon. The side plate 15 and the bottom plate overlap allowance 13c are bonded with an adhesive or the like.

As shown in the development view of FIG. 3, a separation notch 13 cc is formed in the bottom plate overlap margin 13 c. The separation cut 13cc assists the disassembly of the storage box 10 when the paper S stored in the storage box 10 is used up. The separation cut 13cc is formed by perforations. The separation cut 13cc extends from the middle of both sides of the bottom plate overlap margin 13c extending from both ends of the boundary line to the bottom plate 13 so as to approach each other in the short side direction Ds and to approach the bottom plate 13 in the long side direction Dt. 13 is formed so as to meet soon after entering, and as a whole, the curved portion is formed in one broken line shape. The bottom plate overlap allowance 13c is configured such that only the inner side of the separation cut 13cc is adhered to the back surface of the side plate 15 so that the side plate 15 can be separated from the bottom plate 13 when the separation cut 13cc is cut off. Yes.

  Further, the bottom plate 13 is formed with a protruding piece cut 13pc as a protruding piece forming cut capable of forming the protruding piece 13p. The projecting piece 13p has the paper S stored in the storage box 10 when the paper S stored in the storage box 10 decreases and the popped up paper S falls into the storage box 10. It is a member which lifts so that it may approach the outlet 10h. The protruding piece notch 13pc is generally U-shaped. The protruding piece cut 13pc is typically formed by perforations. Between the both ends of the protruding piece cut 13pc formed in a substantially U shape, a linear protruding piece folding line 13pb connecting both ends is formed. The protruding piece folding line 13pb is a ruled line in the present embodiment in order to facilitate the bending of the portion surrounded by the protruding piece cut 13pc. In the present embodiment, two protruding piece cuts 13pc and protruding piece folding lines 13pb are formed near the centroid of the bottom plate 13. The two protruding piece folding lines 13pb extend in parallel to the short side direction Ds and are formed so as to sandwich the centroid of the bottom plate 13 in the long side direction Dt. A protruding piece cut 13pc extending from each protruding piece folding line 13pb is formed so as to protrude to the opposite side of the centroid of the bottom plate 13. The distance from the projecting piece folding line 13pb to the tip of the projecting piece cut 13pc in a direction orthogonal to the projecting piece folding line 13pb is a height at which the paper S in the storage box 10 can be lifted when the projecting piece 13p is formed. .

  With reference to FIGS. 1 to 3, the operation of the paper-containing storage box 1 will be described. The operation of the storage box 10 will be described as part of the operation of the paper-containing storage box 1. In the unopened paper-containing storage box 1, the opposing side 11 a and the width boundary line 11 b of the storage box 10 are connected through a perforation without being cut. When using the paper S of the paper containing box 1 in the consumer's hand for the first time, the opposing side 11a and the width boundary line 11b are completely cut by breaking the perforation. Then, the flap 11f is bent outward at the front / rear boundary line 11c. An outlet 10h is formed by bending the flap 11f. In the present embodiment, since the flap 11f is configured to open to both sides from the opposite side 11a, the outlet 10h can be formed relatively large.

  When the flap 11f is opened, the paper S is taken out from the storage box 10. At this time, since the take-out port 10h is formed to be relatively large, it is easy to put the hand into the storage box 10 from the take-out port 10h and pick the end Se of the paper S. When the paper S stored in the storage box 10 is taken out, the end Se of the half surface Sa of the paper S1 closest to the outlet 10h is picked and pulled out from the outlet 10h. Then, the position of the side Ss that passes through the outlet 10h on the same plane as the top plate 11 is the other front / rear boundary along the width boundary line 11b from the front / rear boundary line 11c side closer to the end Se. It moves toward the line 11c (front and rear boundary line 11c close to the folding line Sc of the paper S1). At this time, since the width interval Db of the take-out port 10h is formed substantially the same as the paper width Ls except for the narrow width portion 10hn, there is almost no resistance when pulling out the paper S1, and it is easy to pull out. On the other hand, since the surface of the paper S is relatively rough, the second paper S2 that is in contact with the first paper S1 is not separated from the paper S1 due to frictional resistance, and is continuous with the paper S1. It may occur that the vehicle exits from the outlet 10h. In the storage box 10 according to the present embodiment, since the narrow width portion 10hn sandwiched between the pair of protrusion portions 11p is formed, when the side Ss of the raised paper S1 reaches the protrusion portion 11p, the paper A frictional force that prevents S from being pulled out works. However, since the edge Se is picked up and pulled up, the paper S1 is pulled up against the frictional force caused by the protrusion 11p. On the other hand, the second sheet of paper S2 tries to stay on the paper group Sg by the frictional force generated by the protrusion 11p. As a result, the first paper S1 and the second paper S2 have forces in opposite directions, and the contact area gradually decreases. Eventually, contact between the surfaces of the papers S1 and S2 disappears, and the paper S1 is separated from the paper S2 and only one sheet is pulled out of the storage box 10. Before the paper S1 is separated from the paper S2, the side Ss of the paper S1 may exceed the protrusion 11p. However, when the paper S1 exceeds the protrusion 11p, the contact area between the papers S1 and S2 is small. Thus, since the frictional force acting between the two papers S1 and S2 is small, the second paper S2 is not connected to the drawn paper S1, and both are separated. When the paper S1 is pulled out, a part of the half surface Sa of the paper S2 sandwiched between the pulled paper S1 is exposed from the outlet 10h.

  The paper S partially exposed from the outlet 10h is sandwiched between a pair of flaps 11f. Thereby, it can suppress that the paper S exposed from the outlet 10h falls in the storage box 10. FIG. The reason why the paper S exposed from the outlet 10h can be sandwiched between the pair of flaps 11f is that the opened flap 11f tries to return to the closed state by elasticity, but is once creased at the front and rear boundary line 11c. This is because they are not completely closed, but are stopped in a half-open state where they are close to each other. Further, in the present embodiment, since the opposing side 11a is formed in a waveform, even when the pair of flaps 11f is half open, the exposed paper S is curved along the waveform of the opposing side 11a, and at a plurality of points. It will be in contact with a pair of flap 11f, and it can control that paper S falls in storage box 10. By maintaining the state in which the paper S is exposed from the take-out port 10h, the paper S can be picked without using the storage box 10 the next time the paper S is used.

  When it is predicted that the paper S will not be used for a while, the paper S sandwiched between the pair of flaps 11f and partially exposed is accommodated in the storage box 10, and the flap 11f is closed to thereby close the paper S. It is possible to prevent water from getting wet or foreign matter such as dust and water droplets from entering the storage box 10. At this time, the flap 11f once closed may be slightly opened by elasticity. In order to eliminate such a state, it is convenient to have a stopper that prevents the closed flap 11f from opening elastically. Therefore, for example, the following stopper may be provided.

  FIG. 4A is a partial perspective view of a storage box 10A according to the modification, and FIG. 4B is a partial cross-sectional view of the storage box 10A according to the modification. FIG. 4B shows a cross section cut by a plane passing through the protrusion 11p and parallel to the front plate 12. FIG. The storage box 10A according to the modification shows an example in which a stopper 11s or a stopper 15s is provided to the storage box 10 described so far. 4A shows a state before the stoppers 11s and 15s are formed, and FIG. 4B shows a state where the stoppers 11s and 15s are formed.

  First, the stopper 11s will be described. The stopper 11s is provided on the top plate 11 near the protrusion 11p. In order to form the stopper 11s, as shown in FIG. 4A, a rectangle is marked on the top plate 11 in the vicinity of the projection 11p, the side closest to the outlet 10h is left as a broken line 11sb, and the remaining 3 Cut one side as a cut line 11sc. The cut line 11sc is preferably formed in advance with a perforation or the like so that it can be easily broken. When the cut line 11sc is cut, the portion surrounded by the cut line 11sc and the fold line 11sb is folded back inside the storage box 10A so as to rotate about the fold line 11sb. Thereby, as shown in FIG. 4 (B), a stopper 11s is formed in which the tip protrudes toward the outlet 10h from the width boundary line 11b. In addition, the cut line 11sc may have a curved shape such as an arc shape in addition to the shape formed by three straight lines orthogonal to each other. That is, the stopper 11s may have a shape other than a rectangle.

  Next, the stopper 15s will be described. The stopper 15 s is provided at the upper center of the side plate 15. In order to form the stopper 15s, as shown in FIG. 4A, a rectangle is marked at the upper center of the side plate 15, the side closest to the top plate 11 is left as a broken line 15sb, and the remaining three sides are cut 15sc. Disconnect as. The cut line 15sc is preferably formed in advance with a perforation or the like so that it can be easily broken. When the cut line 15sc is cut, the portion surrounded by the cut line 15sc and the fold line 15sb is turned inside the storage box 10A so as to rotate around the fold line 15sb. As a result, as shown in FIG. 4B, a stopper 15s is formed in which the tip protrudes toward the outlet 10h from the width boundary line 11b. Note that the bottom plate overlap allowance 13c existing on the locus when the stopper 15s rotates may be cut out in advance. Further, the cut line 15sc may have a curved shape such as an arc shape other than the shape composed of three straight lines orthogonal to each other. That is, the stopper 15s may have a shape other than a rectangle.

  In FIG. 4, for convenience of explanation, the storage box 10 </ b> A is shown as having both the stopper 11 s and the stopper 15 s, but one of the stopper 11 s and the stopper 15 s may be provided. If the closed flap 11f is put inside the storage box 10A rather than the stopper 11s or the stopper 15s, the flap 11f to be opened can be suppressed. The stopper 11s or the stopper 15s can suppress both the pair of flaps 11f. When the stopper 15s is provided, instead of the upper center of the side plate 15, one may be provided on the left and right of the upper side of the side plate 15, and each stopper 15s may be configured to suppress the pair of flaps 11f one by one. When one stopper 15s is provided on the left and right of the upper part of the side plate 15, in addition to the bottom plate stacking allowance 13c existing on the locus when the stopper 15s rotates, the front plate overlap existing on the locus when the stopper 15s rotates. The allowance 12c and the back plate overlap allowance 14c may be cut out in advance.

  With reference to FIG. 1 thru | or FIG. 3 again, description of the effect | action of the storage container 1 is continued. If the paper S is used and the paper S in the storage box 10 is reduced, it may be difficult to appropriately sandwich the paper S partially exposed from the outlet 10h with the pair of flaps 11f. In this case, the protruding piece cut 13pc of the bottom plate 13 is cut by breaking the perforation. Then, the portion surrounded by the protruding piece cut 13pc is bent toward the inside of the storage box 10 along the protruding piece folding line 13pb. Thereby, the protrusion 13p which protrudes into the inside of the storage box 10 will be formed. When the protruding piece 13p is formed, the paper group Sg in the storage box 10 is brought close to the outlet 10h by the protruding piece 13p. Then, the remaining surface Sb of the paper S partially exposed from the take-out port 10h approaches the take-out port 10h, and the paper S exposed from the take-out port 10h is prevented from falling into the storage box 10. it can.

  When the paper S accommodated in the storage box 10 is used up, the storage box 10 can be easily flattened by breaking the perforated line 13cc and the separation notch 13cc formed in the bottom plate 13 to break. Can be folded. When cutting the separation notch 13cc, in this embodiment, the separation notch 13cc formed in the bottom plate overlap allowance 13c is under the side plate 15 and cannot be seen. The separation cut 13cc may be cut. When the separation cut 13cc of the bottom plate 13 portion is cut, a thumb is put into the storage box 10 from that portion, and the remaining four fingers are attached to the side plate 15. Next, the side plate 15 and the bottom plate overlap margin 13c sandwiched by hands are opened outward with the intersection line between the top plate 11 and the side plate 15 as the center. Then, the perforation of the separation notch 13cc formed in the bottom plate overlap allowance 13c is broken, and the side plate 15 is separated from the bottom plate 13. When the side plate 15 and the bottom plate 13 are separated from each other, the front plate overlap allowance 12c and the rear plate overlap allowance 14c are not bonded to any part, so that the storage box 10 has a rectangular tube shape with both ends opened. If it becomes a square cylinder shape, the storage box 10 can be made flat, for example by folding so that the surface of the front plate 12 and the top plate 11 may contact the surface of the bottom plate 13 and the rear plate 14. By folding the storage box 10 flat, bulkiness at the time of disposal can be suppressed.

  As described above, according to the storage box 10 according to the present embodiment, the width interval Db is substantially the same as the paper width Ls except for the narrow width portion 10hn. The paper S can be pulled out smoothly. Further, since the narrow width portion 10hn is formed at the outlet 10h, even when the paper S having a relatively rough surface is folded by the pop-up method, the second paper S2 is also connected to pull out the surface paper S1. It can be prevented from being pulled out. Moreover, since the protruding piece cut 13pc is formed on the bottom plate 13, the protruding piece 13p can be protruded into the storage box 10 when the paper S in the storage box 10 is reduced, and the paper S is raised. And it can suppress that the paper S exposed from the outlet 10h falls in the storage box 10. FIG. Moreover, since the separation cut 13cc is mainly formed in the bottom plate overlap allowance 13c, the storage box 10 can be easily folded flat when the paper S is used up, and the bulk at the time of disposal is suppressed. Can do.

  In the above description, the paper S is manufactured by the air bonded method and the chemical bond method using spray using natural pulp as a main raw material, but may be manufactured by a method other than these. Moreover, although embossing was given to the paper S, the embossing does not need to be attached.

  In the above description, the width interval Db is substantially the same as the paper width Ls except for the narrow width portion 10hn. However, the width interval Db is larger than 3% with respect to the paper width Ls. It may be formed small. When the width interval Db is narrower than the paper width Ls at any position on the width boundary line 11b, the narrow width portion 10hn is formed over the entire width boundary line 11b. In this case, the ease of pulling out the paper S is sacrificed, but the surface paper S1 can be reliably separated from the second paper S2. In the above description, the width boundary line 11b is shorter than the front and rear boundary line 11c, but may be longer than the front and rear boundary line 11c. It may be the same length. When the length of the width boundary line 11b and the length of the front and rear boundary line 11c are the same, the basic shape of the outlet 10h is a square.

  In the above description, the flaps 11f are configured as a pair connected to the respective front and rear boundary lines 11c. However, the flaps 11f may be configured as a single sheet connected to one front and rear boundary line 11c. In the above description, the flap 11f is configured to be able to open and close with the front / rear boundary line 11c as an axis. However, the connecting portion between the flap 11f and the top plate 11 can be cut through the cut line Cc. If the flaps 11f are not necessary, the flaps 11f may be easily removed. When the flap 11f is removed, the flap 11f is not obstructed when the paper S is pulled out. On the other hand, if the flap 11f is not removed and the flap 11f is closed when the paper S is not used, entry of foreign matter into the storage box 10 can be prevented.

  In the above description, the sheet-like material is kitchen paper, but it may be sanitary paper other than kitchen paper or industrial sheets such as waste cloth. The storage box 10 according to the present embodiment is suitable when applied to a sheet-like object having a characteristic that the second sheet is brought out in a row when the first sheet is pulled out by being folded in a pop-up method. .
