Description

  The present invention relates to a folded sheet storage box. More specifically, the present invention relates to a sheet storage box provided with an opening through which folded sheets such as a nonwoven fabric sheet, a woven fabric sheet, and a paper sheet can be sequentially taken out from the storage box one by one.

  Sheet laminate storage boxes are widely used as, for example, tissue paper storage boxes. Various types of storage boxes have been proposed in which tissue paper can be sequentially taken out one by one (Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5).

However, these proposed storage boxes are effective for storing a low slip angle (for example, less than 20 degrees) in the slip angle test method between sheets, but the slip angle in the slip angle test method between sheets. Does not work well for storage of large items. That is, in the conventional storage boxes such as these proposals, even if only one sheet is to be taken out, two or more sheets are taken out in succession, causing a problem in use.

  Since the sheet storage box of the present invention forms the long hole opening for taking out the nonwoven fabric as described above, the nonwoven fabric sheet, the woven fabric sheet, and the paper sheet in the storage box can be reliably taken out one by one. In addition, the sheet storage box of the present invention does not need to use a resin film or the like that has conventionally been provided at the outlet of the storage box, can reduce manufacturing costs, and can reduce the amount of resources used. In addition, since the separation process is not required when discarding after use, the reusability of resources is excellent.

  The sheet storage box of the present invention is useful as a storage box for non-woven sheets such as cleaning sheets, woven sheets such as cooking sheets, and paper sheets such as tissue paper. In particular, it is useful as a storage box for a sheet having a high sliding angle (for example, 30 degrees or more) such as a nonwoven fabric sheet or a woven fabric sheet.

  In the sheet storage box of the present invention, it is easy to return the once taken out sheet to the storage box.

  The present invention will be described in detail below.

  FIG. 1 is a plan view showing an example of an upper surface shape of the sheet storage box 1 of the present invention. In FIG. 1, reference numeral 11 denotes a long hole opening for taking out a nonwoven fabric sheet (after opening, it becomes an opening lid), which has a substantially elliptical long axis aligned with the length direction of the storage box 1. Reference numeral 13 denotes a stored nonwoven fabric sheet. Reference numerals 15 and 17 denote arc-shaped portions in which the nonwoven fabric sheet 13 is in sliding contact with the elongated hole opening when the nonwoven fabric sheet 13 is taken out. The arcuate portions 15 and 17 are formed with notches 21 and 23, respectively, facing outward in the width direction of the storage box 1. By forming the notches 21 and 23 in the arc-shaped portions 15 and 17, shoulder portions 31, 33, 35 and 37 are formed in the arc-shaped portions 15 and 17. The shoulder portions 31, 33, 35, and 37 increase the sliding resistance between the nonwoven fabric sheet 13 and the long hole opening 11 when the nonwoven fabric sheet is taken out.

  BL is the length in the longitudinal direction of the storage box 1 (285 mm), BW is the length in the width direction of the storage box 1 (126 mm), CL is the length in the longitudinal direction of the folded portion 19 of the folded nonwoven fabric sheet 13 (276 mm), CW is the length of the folded nonwoven fabric sheet 13 in the width direction (120 mm), ML is the maximum length in the longitudinal direction of the opening 11 (210 mm), and MW is the width of the opening 11 The maximum length (85 mm), SL1 is the longitudinal length of one notch 21 of the opening 11 (70 mm), SL2 is the longitudinal length of the other notch 23 (65 mm), and DW1 is one of the openings 11 The notch 21 has a width direction length (15 mm), and DW2 is a width direction length of the other notch 23 of the opening 11 (15 mm).

  The upper surface of the storage box 1 is perforated along the shape of the opening 11 in advance. However, the outward hinge 25 of the notch 23 is not perforated. In use, the perforation is cut and folded upward by the hinge portion 25 to form the opening 11 and the cut portion can be used as the opening lid 27 described later.

  FIG. 2 and FIG. 3 show an example of a cross-sectional view taken along the line aa in FIG. 1 (an example in which a nonwoven fabric sheet is folded and stored in two). In FIG. 2, reference numeral 40 a denotes a nonwoven fabric sheet that is being taken out from the storage box 1. 40b is a nonwoven fabric sheet to be taken out next to 40a. The nonwoven fabric sheet 40 a is in sliding contact with the shoulder portions 35 and 37 of the opening 11 of the storage box 1. The shoulder portions 35 and 37 function to increase the sliding resistance between the nonwoven fabric sheet 40a and the long hole opening 11 when the nonwoven fabric sheet is taken out.

  In FIG. 3, 40a is the nonwoven fabric sheet already taken out, 40b is the nonwoven fabric sheet which should be taken out next to the nonwoven fabric sheet 40a. The nonwoven fabric sheet 40 b is in sliding contact with the shoulder portions 31 and 33 of the opening 11 of the storage box 1. The shoulder portions 31 and 33 function to increase the sliding resistance between the nonwoven fabric sheet 40b and the long hole opening 11 when the nonwoven fabric sheet is taken out. By this function, the nonwoven fabric sheet 40b can remain in the storage box 1 without being pulled out by the nonwoven fabric sheet 40a.

  Note that BH in FIGS. 2 and 3 is the height (65 mm) of the storage box. The nonwoven fabric sheet has a sliding angle between the nonwoven fabric sheets of 41.2 degrees.

  Although an example of the present invention has been described as described above, the present invention is not limited thereto, and the present invention can be as follows.

  In the present invention, the maximum length ML in the longitudinal direction of the opening 11 is preferably 60 to 80% of the length CL in the longitudinal direction of the nonwoven fabric sheet folding portion 19. When this ratio exceeds 80%, when trying to take out the nonwoven fabric sheet 13 from the storage box 1 one by one, two or more nonwoven fabric sheets may be taken out continuously. On the other hand, when this ratio is less than 60%, it is difficult to take out the nonwoven fabric sheet when taking out the nonwoven fabric sheets 13 from the storage box 1 one by one.

  In the present invention, the longitudinal length SL1 and / or SL2 of the cutout portion of the opening 11 is preferably 10 to 60% of the longitudinal length CL of the nonwoven fabric sheet folded portion 19. When this ratio exceeds 60% or less than 10%, when trying to take out the nonwoven fabric sheet 13 from the storage box 1 one by one, two or more nonwoven fabric sheets may be taken out in succession. .

  In this invention, it is preferable that the maximum length MW of the width direction of an opening part is 15 to 70% of the length CW of the width direction of a nonwoven fabric sheet folding part. When this ratio exceeds 70%, when trying to take out the nonwoven fabric sheet from the storage box one by one, two or more nonwoven fabric sheets may be taken out continuously. On the other hand, when the ratio is less than 15%, it is difficult to take out the nonwoven fabric sheet when trying to take out the nonwoven fabric sheet one by one from the storage box. Moreover, when this ratio is less than 15%, it becomes difficult to store the nonwoven fabric sheet once taken out from the opening in the storage box. In particular, in the case where a portion in which the opening is cut is used as the opening lid, it is difficult to store the nonwoven fabric sheet from the opening in the storage box. For the above reasons, the maximum length MW in the width direction of the opening is particularly preferably 30 to 70% of the length CW in the width direction of the nonwoven fabric sheet folded portion.

  In this invention, it is preferable that the length direction length DW1 and / or DW2 of the notch part of an opening part are 5 to 30% of the length CW of the nonwoven fabric sheet folding part. When this ratio exceeds 30%, when trying to take out the nonwoven fabric sheet from the storage box one by one, the nonwoven fabric sheet may not be smoothly taken out. On the other hand, when the ratio is less than 5%, two or more non-woven sheets may be taken out in succession when trying to take out the non-woven sheets one by one from the storage box.

  FIG. 4 and FIG. 5 show another example of the cross-sectional view taken along the line aa in FIG. 1 (an example in which the nonwoven fabric sheet is folded and stored in three folds). In FIG. 4, reference numeral 50 a denotes a nonwoven fabric sheet that is being taken out from the storage box 1. 50b is a nonwoven fabric sheet to be taken out next to the nonwoven fabric sheet 50a. The nonwoven fabric sheet 50 a is in sliding contact with the shoulder portions 31 and 33 of the opening 11 of the storage box 1 as illustrated. The shoulder portions 31 and 33 function to increase the sliding resistance between the nonwoven fabric sheet and the long hole opening 11 when the nonwoven fabric sheet is taken out.

  In FIG. 5, 50a is the nonwoven fabric sheet already taken out, 50b shows the nonwoven fabric sheet which should be taken out next to the nonwoven fabric sheet 50a. The nonwoven fabric sheet 50b is in sliding contact with the opening 11 and the shoulders 31 and 33 of the storage box 1 as illustrated. The shoulder portions 31 and 33 function to increase the sliding resistance between the nonwoven fabric sheet and the long hole opening 11 when the nonwoven fabric sheet is taken out. With this function, the nonwoven fabric sheet 50b can stay in the storage box 1 without being pulled out by the nonwoven fabric sheet 50a.

  When the nonwoven fabric sheet is folded in three (also referred to as Z-fold), the sliding contact portion between the opening 11 of the storage box 1 and the nonwoven fabric sheet when the nonwoven fabric sheet is taken out is always only on one side of the storage box. Therefore, when the nonwoven fabric sheet laminate to be stored is three-folded, the cutout of the opening may be only one of the long sides. 6 and 7 show another example of the shape of the opening 11 of the storage box when the nonwoven fabric sheet is folded in three.

  FIG. 8 is a plan view before the perforation 66 of the storage box 1 in FIG. 1 is cut, and FIG. 9 is a plan view in which the perforation 66 is cut and the opening lid 27 is folded upward by the hinge portion 25. FIG. 10 is a cross-sectional view taken along the line bb in FIG. The hinge portion 25 may have a rough perforation for facilitating folding.

  In FIG. 8, the opening 11 is formed in the storage box 1 by incising the perforation 66 and turning the opening lid 27 back by the hinge portion 25. A substantially semicircular knob 61 is formed on the side of the opening lid 27 facing the hinge 25. The knob portion 61 protrudes outward and is cut out in a semicircular shape with a small diameter, whereby a latching piece 63 is formed. The hooking piece 63 is protruded below the opening lid 25 by bending the knob 61 with a bent part 64 along the diameter of the semicircular hooking piece 63. In FIG. 9, reference numeral 81 denotes a latching opening formed by punching the adhesive margin 79 of the storage box 1 in a semicircular shape. The opening lid 27 can be fixed to the storage box 1 by engaging the retaining piece 63 with the retaining opening 81. FIG. 10 shows a state in which the latching piece 63 is engaged with the latching opening 81.

  It is preferable that the sheet | seat in this invention is a nonwoven fabric sheet. For example, it is preferable that the nonwoven fabric sheet contains polyolefin fibers, polyester fibers, and rayon fibers as constituent components because the cleaning function becomes good when the sheet is used for cleaning.

In the present invention, the material of the storage box is preferably paper. In particular, it is preferably a paperboard having a thickness of 0.2 to 1.0 mm (US basis weight is 200 to 600 g / m ² ). Printing is preferably performed on the outside of the storage box.

  In the present invention, the sheet preferably has a slip angle (hereinafter simply referred to as “slip angle”) of 30 degrees or more in a slip angle test method between sheets. The upper limit of the slip angle of the nonwoven fabric sheet in the present invention is preferably 55 degrees in the test method. When the slip angle exceeds 55 degrees, when trying to take out the nonwoven fabric sheets one by one from the storage box, two or more nonwoven fabric sheets may be taken out in succession. On the other hand, when the slip angle of the nonwoven fabric sheet is less than 30 degrees, the cleaning function may be insufficient when the nonwoven fabric sheet is used for cleaning.

  In addition, the slip angle of the sheet in the present invention was measured by the following method according to the method for measuring the friction coefficient of paper and paperboard according to JIS P 8174 (1994).

(1) Slip angle tester The tester body is equipped with an inclined plate attached with a hinge so as to be parallel to the fixed base to which the level is attached. The tilt plate is provided with a scale plate that can indicate the tilt angle in units of 1 degree. A grip for fixing the test piece is attached to the upper end of the inclined plate, and a stopper is attached to the lower end. The material of the inclined plate is made of a smooth metal, and its dimensions are 25 mm or more wider than the width of the weight and have a length that can move the weight by 15 mm or more.

The weight is a metal block with a rectangular flat bottom, with a grip to hold the specimen. The weight has a width of 60 mm, a length of 100 mm, and a mass of 1000 g. The pressure applied to the bottom surface of the weight is 1.64 kPa (16.7 gf / cm ² ).

(2) Test piece (a) Sample preparation As the sample, one sampled according to test standard A29 “Test paper sampling standard” is used. One full-width sample is folded into five at almost equal intervals so that the flow directions are parallel to each other, and the central part thereof is divided by a rice-basis plate to make a test sample.

(B) Specimen Avoid abnormal parts such as unevenness, creases, creases, bends, wrinkles, and wrinkles from the specimens, and correctly place the weight specimen and the flat specimen in the following dimensions. Cut.

  The test piece for the weight is 60 mm × 190 mm, and five pieces are cut in the vertical direction. The flat plate test piece is 100 mm × 250 mm, and is cut into five pieces in the vertical direction.

  The number of tests shall be 5 times per sample.

  The operation is performed in a test chamber that matches the standard conditions after pre-processing according to the conditions of test standard A30 “Test Paper Pre-processing Standards”.

(3) Sliding angle measurement Instrument setting While looking at the level of the tester body, level the body with the four adjusting legs and fix it with a lock nut. The inclined plate is set at the 0 degree position. The test piece for weight and the test piece for flat plate are set on the inclined plate and the moving block, respectively. Turn on the power and raise the inclined plate at a predetermined speed. The friction between the set samples becomes the limit, and ascending of the inclined plate stops as soon as the moving block starts to slide. The angle of the inclined plate at this time is read by the indicated value of the pointer and is set as the sliding angle. The average value of the five measurements is taken as the slip angle of the nonwoven sheet.

  In the above example, the present invention has been described using the nonwoven fabric sheet. However, the present invention is not limited to this, and a laminate of a woven fabric sheet (for example, a cooking sheet) and a paper sheet (for example, tissue paper) can also be accommodated.

  Thus, the sheet | seat in this invention is a nonwoven fabric sheet, a woven fabric sheet, a paper sheet etc. with the unevenness | corrugation and fluff (raising) on the surface, and may contain a detergent and a water | moisture content. When the sheet is a paper sheet, the sliding angle may be 45 degrees or less, preferably 20 degrees or more and less than 30 degrees. By making the sliding angle 45 degrees or less, it is possible to prevent the paper sheet from being continuously taken out. In particular, by setting the angle to 20 degrees or more and less than 30 degrees, it is possible to reliably prevent the paper sheet from being continuously taken out.
