[ integral Structure ]

As shown in fig. 1, the sanitary tissue paper storage container 100 includes: a container body 1 in which sanitary tissue paper is stored; a lid body 2 detachably attached to the container body 1 so as to cover the opening; and a take-out section 3 detachably attached to the lid body 2.

Since the lid body 2 is configured to be detachable from the container body 1, the sanitary thin paper can be stored in the container body 1 or taken out from the container body 1 in a state where the lid body 2 is detached from the container body 1.

[ sanitary tissue paper ]

The sanitary tissue paper is roll paper such as wet tissue or wet tissue wound in a roll shape, and is stored in the container body 1 in a state wound in a roll shape around an axial center along the Z-axis direction (height direction). In the sanitary tissue paper, perforation lines are applied at regular intervals in the longitudinal direction, and the user uses the sheet cut along the perforation lines.

In the following, a case where the sanitary tissue paper is pulled out from the center side of the roll will be described, but the sanitary tissue paper is not limited to this, and the sanitary tissue paper may be pulled out from the outside.

[ Container body ]

As shown in fig. 1 and 2, the container body 1 is a container for containing sanitary tissue paper, and is formed in a bottomed cylindrical shape, and has an opening portion on an upper surface. As shown in fig. 2, a male screw portion 11 is provided along the circumferential direction on the outer surface side of the upper end portion of the side surface.

The container body 1 is integrally formed by injection molding, two-color molding, blow molding, or the like using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, or the like.

The container body 1 is formed in a circular shape having a diameter of preferably 60 to 200mm, more preferably 65 to 110mm, in a plan view, preferably 175 to 200mm, more preferably 175 to 185mm in a Z-axis direction (height direction), and preferably 0.05 to 10.00mm, more preferably 0.10 to 5.00mm in thickness on each surface.

[ cover ]

As shown in fig. 1 and 2, the lid body 2 is composed of a lid body 21 and a small lid 22.

(cover body)

The lid body 21 is integrally formed by injection molding, two-color molding, blow molding, or the like using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, or the like. The bottom surface of the cylindrical body is open, and the cylindrical body includes a top surface portion 21a, a side surface portion 21b, a recessed portion 21c formed in a downward concave shape on the inner peripheral side in a plan view of the top surface portion 21a, a hole portion 21d, and a main body side wall portion 21e erected in a cylindrical shape in the recessed portion 21c so as to surround the hole portion 21 d.

The lid body 21 is formed in a circular shape having a diameter of preferably 60 to 200mm, more preferably 65 to 110mm in a plan view, and is formed in a cylindrical shape having a thickness of preferably 15 to 50mm, more preferably 33 to 45mm in a Z-axis direction (height direction), and preferably 0.05 to 10.00mm, more preferably 0.10 to 5.00mm in each surface.

(Top surface)

As shown in fig. 1 and 2, the top surface portion 21a is a portion on the outer peripheral side of the upper surface of the cover main body 21 formed in a cylindrical shape except for the recess 21 c.

(side surface part)

As shown in fig. 1 and 2, the side surface portion 21b is a portion forming a side surface of the cover body 21 formed in a cylindrical shape.

An internal thread portion 211 screwed with the external thread portion 11 of the container body 1 is provided on the inner surface side of the lower end portion of the side surface portion 21 b. As a result, as shown in fig. 2, the container body 1 and the lid body 2 adopt a detachable connection structure via the external thread portion 11 and the internal thread portion 211, and the lid body 2 can be detached from the container body 1.

(concave part)

The recess 21c is formed so that the shape thereof in plan view substantially matches the shape of the small lid 22 when closed, and the small lid 22 can be fitted therein. The recess 21c is formed such that the tip end portion is larger than the small lid 22 in a plan view, and a slight gap is left even in a state where the small lid 22 is fitted. This allows the finger to be hooked to the small lid 22 through the gap.

(hole part)

The hole 21d is a hole formed in the substantially center of the lid body 21 in a circular shape in a plan view and communicating with the inside of the sanitary tissue paper storage container 100, and is formed slightly smaller than the takeout portion 3 in a plan view, and the takeout portion 3 is fixed to the hole 21d as described later.

(side wall of the main body)

The main body side wall portion 21e is formed to extend upward in a cylindrical shape in the recess portion 21c so as to surround the periphery of the hole portion 21 d. The main body side wall portion 21e is formed to have an outer diameter equal to or slightly smaller than an inner diameter of the small lid side wall portion 22a formed in the small lid 22.

(Small cap)

The small lid 22 is integrally formed by injection molding, two-color molding, blow molding, or the like using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, or the like, and includes a small lid side wall portion 22a protruding from the lower surface when closed. The small lid 22 is formed so that its shape in plan view when closed substantially matches the recess 21c, and can fit into the recess 21c when closed.

(side wall of small lid)

The small lid side wall portion 22a is formed in a cylindrical shape extending downward when the small lid 22 is closed. The inner diameter of the small lid side wall portion 22a is formed to be the same as or slightly larger than the outer diameter of the main body side wall portion 21 e. When the small lid 22 is closed, the small lid side wall portion 22a contacts the upper surface of the recess 21 c. Thus, when the small lid 22 is closed, the small lid side wall portion 22a and the main body side wall portion 21e are fitted to each other, and the space surrounded by the small lid side wall portion 22a and the main body side wall portion 21e can be maintained, and further, the airtightness of the interior of the sanitary tissue paper storage container 100 connected to the space via the hole portion 21d can be maintained.

In the present embodiment, the main body side wall portion 21e and the small lid side wall portion 22a are fitted to each other to maintain airtightness inside the container main body 1, but a structure different from the above may be employed as long as airtightness inside the container main body 1 can be maintained.

Further, when the stored sanitary thin paper does not have to be prevented from drying because it does not contain chemicals, it may be configured without providing any airtight means.

[ removal part ]

As shown in fig. 3 and 4, the extraction portion 3 is an elastically deformable member (extraction member) formed in a substantially cylindrical shape that is circular in a plan view. Fig. 4 is a bottom view of the extraction unit 3, and shows a state in which the extraction unit 3 of fig. 3 is viewed from below.

Specifically, the extraction portion 3 includes a recess 31 having an inner bottom surface 3a formed in a central portion in a plan view, a constricted portion 32 formed in a side surface, an extraction hole 33 formed in a substantially central portion in the recess 31 (inner bottom surface 3a) in the plan view, and a chamfered portion 34 formed by chamfering a peripheral edge portion of the extraction hole 33 in the lower surface 3 b.

The thickness R1 (see fig. 5) of the taking-out portion 3 in the Z-axis direction below the constricted portion 32 (the dimension between the inner bottom surface 3a and the lower surface 3 b) is 1.0mm to 5.0mm, preferably 1.5mm to 3.0 mm.

(concave part)

The recess 31 is formed to have a circular shape in a plan view and to be recessed downward, with a peripheral edge portion left on the upper surface of the removal portion 3. The concave portion 31 is formed such that the inner bottom surface 3a thereof is flat.

The concave portion 31 is formed such that the inner bottom surface 3a thereof is flat.

(contraction part)

The constricted portion 32 is formed in a groove shape that is radially recessed so as to have a depth of one twentieth or more and one tenth or less of the diameter of the extraction portion 3 in a plan view, so as to circumferentially surround a substantially central portion in the vertical direction of the side surface of the extraction portion 3. As described above, since the removal portion 3 is formed slightly larger than the hole portion 21d in a plan view, the removal portion 3 can be fixed to the lid body 21 by fitting the edge portion of the hole portion 21d into the constricted portion 32.

(taking out hole)

The taking-out hole 33 is a hole for taking out the sanitary tissue paper stored in the container body 1.

The taking-out hole 33 holds the sanitary tissue inserted from the lower surface 3b side in a state where the leading end thereof protrudes from the upper surface of the taking-out section 3 (the inner bottom surface 3a of the recess 31).

When the leading end of the sanitary tissue paper is in a state of protruding from the upper surface of the takeout section 3, the protruding amount is 5mm to 39mm, preferably 13mm to 20 mm. By setting the projection amount to 5mm or more, the user can easily grasp the tool with his or her finger, and the user can easily take out the tool. Further, by setting the projection amount to 39mm or less, the end of the sanitary thin paper does not fly out when the lid body 2 is closed.

The extraction hole 33 is formed by a notch 330 in which two straight lines cross each other in a cross shape at substantially the center of the extraction portion 3 in a plan view.

As shown in fig. 4, the cutout portion 330 includes, for example: four straight line portions 331; a first circular portion 332 provided at a portion where one ends of the linear portions 331 intersect; and a second circular portion 333 provided at the other end of the linear portion 331 and having a smaller diameter than the first circular portion 332.

The overall length of the notch 330 is 5mm to 30mm, preferably 10mm to 15mm, and is set to be about 15mm or more, for example, the width of the index finger of a normal user. By forming the cut-out portion 330 with a cross-shaped cut, the reliability of holding the sanitary tissue paper in the cut-out portion 330 can be further improved.

The diameter of the first circular portion 332 is formed to be 2.5mm to 4.0mm, and by providing the first circular portion in this way, the exposed portion gripped by the take-out portion 3 after the sheet is taken out can be extended. Further, by providing the second circular portion, the sheet can be taken out with a small force.

In fig. 4, the case where the extraction hole 33 is formed in a cross shape has been illustrated and described, but the shape of the extraction hole 33 is not limited thereto, and any shape may be selected as long as the above-described function can be exerted. That is, the radial cuts may be formed by three or more linear cuts. The extraction hole 33 may be formed by a single linear slit, and may have a circular shape, an elliptical shape, a substantially star shape, or the like.

(chamfered part)

As shown in fig. 4 and 5, the chamfered portion 34 is a region formed by chamfering an angle formed by the lower surface 3b of the taking-out portion 3 and the hole wall 33a of the taking-out hole 33.

Specifically, the chamfered portion 34 is a planar chamfered portion formed by chamfering the edge portion of the hole wall 33a of the taking-out hole 33 in an inclined plane on the lower surface 3b of the taking-out portion 3, and thus the taking-out hole 33 has a shape in which the opening area on the lower end side is larger than the opening area on the upper end side.

As shown in fig. 6, the size of the chamfered portion 34 is preferably set such that a length L1 in the width direction (direction along the XY plane) of the extraction hole 33 from the hole wall 33a of the extraction hole 33 is in the range of 0.5mm to 1.0mm, and a length L2 in the height direction (direction along the Z axis) of the extraction hole 33 from the lower end is in the range of 0.5mm to 1.0 mm.

Here, although the case where the chamfered portion 34 is formed by chamfering with a flat surface has been illustrated and described, the chamfered portion 34 may be a curved chamfered portion formed by chamfering an angle formed by the lower surface 3b of the extraction portion 3 and the hole wall 33a of the extraction hole 33 into a convex curved surface as shown in fig. 7.

The taking-out member forming the taking-out section 3 needs to be insertable into the hole 21d, not to come off from the cover body 21 when the sanitary tissue storage container 100 is used, and to be capable of pressing the sanitary tissue into the taking-out hole 33 with a finger, and therefore, it is necessary to form the taking-out member using a material having a certain elasticity. Specifically, the hardness is preferably 50 to 70. The hardness can be measured according to JIS K6253 (type a durometer).

Specifically, for example, the elastomer composition can be formed by injection molding using an elastomer such as styrene-butadiene, polyester, polyethylene, or polyurethane.

When coloring the take-out portion 3, for example, a mixture of a resin such as PE (polyethylene) and an arbitrary pigment is mixed with the elastomer (pigment adding step). In this case, the extraction performance of the sanitary tissue paper by the extraction section 3 can be adjusted by changing the mixing ratio of the elastomer and PE as the resin.

Here, the resin mixed with the elastomer may be any resin as long as it has a higher hardness than the elastomer.

In the taking-out section 3, when the force required for pulling out the sanitary tissue paper is measured 5 times by using a digital load cell (model DS2-200N manufactured by Emenda, Japan) and the average value is defined as the resistance value, the resistance value is preferably in the range of 5N to 12N, more preferably in the range of 6N to 10N.

When the sanitary tissue paper wound in one roll is pulled out (for example, 80 sheets are connected to each other and have 79 perforation lines), the allowable range of the number of times (continuous number of times) that the subsequent sanitary tissue paper is continuously taken out without cutting the perforation lines is 10 times or less, preferably 7 times or less.

The present invention has been specifically described above based on the embodiments, but the present invention is not limited to the above embodiments, and can be modified within a range not departing from the gist thereof.

For example, the sanitary tissue paper stored in the sanitary tissue paper storage container 100 is not necessarily wound in a roll shape, and for example, a so-called pop-up sheet may be used in which sheets are stacked in an alternately folded state and a next sanitary tissue paper is pulled up to the take-out hole 33 when one sanitary tissue paper is taken out.

The sanitary tissue paper storage container 100 is not necessarily cylindrical, and may be formed in a polygonal column shape such as a pentagon or a hexagon in a plan view.

Examples

Next, the results of evaluating the change in the taking-out performance of the sanitary tissue paper accompanying the change in the mixing ratio of the elastic body and PE in the taking-out section 3 will be described with respect to the examples of the present invention. The present invention will be specifically described below with reference to examples, but the present invention is not limited thereto.

[ sample preparation ]

As the sanitary tissue paper storage container 100, a PE container having a shape shown in fig. 1 and having a container body 1 and a lid body 2 detachably attached to the container body 1 was prepared.

The following takeout section 3 of examples 1 to 5 was attached to the lid body 2 of the sanitary tissue paper storage container 100.

(example 1)

The extraction part 3 was prepared by mixing an elastomer obtained by mixing a styrene-based thermoplastic elastomer and an acrylic elastomer with PE at a ratio of 100: 5.

The taking-out section 3 has a shape shown in fig. 3 to 7, a thickness in the Z-axis direction excluding the concave section 31 is 3.0mm, and the hardness of the taking-out section 3 based on the measurement by a type a durometer in accordance with JIS K6523 is 58.3.

The extraction hole 33 has a cross shape as shown in fig. 4 in a plan view, and the total length of the extraction hole 33 is 29mm in a plan view.

Examples in which the lengths L1 and L2 of the chamfered portion 34 were set to L1-L2-0.5 mm and L1-L2-1.0 mm are example 1 and example 2, respectively.

Further, L1 is a length in the XY plane direction, and L2 is a length in the Z axis direction.

(example 2)

The hardness of the take-out section 3 was 70 as measured by a type a durometer in accordance with JIS K6523.

Other conditions were the same as in example 1.

(example 3)

The hardness of the take-out section 3 was 80 based on the measurement by a type a durometer in accordance with JIS K6523.

Other conditions were the same as in example 1.

(example 4)

The extraction part 3 was prepared by mixing an elastomer obtained by mixing a styrene-based thermoplastic elastomer and an acrylic elastomer with PE at a ratio of 100: 7.5.

At this time, the hardness of the taking-out portion 3 based on the measurement by a type a durometer in accordance with JIS K6523 was 59.1.

Other conditions were the same as in example 1.

(example 5)

The extraction part 3 was prepared by mixing an elastomer obtained by mixing a styrene-based thermoplastic elastomer and an acrylic elastomer with PE at a ratio of 100: 10.

At this time, the hardness of the taking-out portion 3 based on the measurement by a type a durometer in accordance with JIS K6523 was 60.5.

Other conditions were the same as in example 1.

The following tests were carried out using the samples provided with the taking-out part 3 of examples 1 to 5.

[ test 1. Change in Performance due to change in hardness of the removed portion ]

Sanitary tissue paper, which is a wet sheet wound in a roll shape and is formed by connecting 80 sheets having 79 perforation lines applied thereto at regular intervals in the longitudinal direction, is housed in the container body 1 of the sanitary tissue paper housing container 100 provided with each sample.

Next, the following tests were performed 5 times for each of the extraction portions 3 of the examples: the cover 2 was attached so that the end of the sanitary tissue paper protruded from the taking-out hole 33, the end of the protruded sanitary tissue paper was pulled upward, and all sheets of 80 sanitary tissue papers were taken out, and (1) the number of falls, (2) the number of continuous times, (3) the average length of the exposed portion, (4) the standard deviation, (5) the appropriate exposed portion ratio, and (6) the cross resistance were measured as follows.

(1) Number of falls

After the sheets were pulled out using the respective samples, the average of the number of times the sanitary tissue fell into the container body 1 due to the taking-out section 3 not sufficiently gripping the end of the sanitary tissue was calculated as the number of falls.

(2) Number of consecutive times

When the sheet was pulled out using each sample, the average of the number of times that the subsequent sheet was continuously pulled out without cutting the perforation line was calculated as the continuous number.

(3) Average length of exposed part

After the sheet was pulled out using each sample, the average length of the end of the sanitary tissue held by the take-out section 3 was calculated as the exposed portion average length.

(4) Standard deviation of

Calculating the standard deviation of the average length of the exposed portion described in (3).

(5) Proper exposed part ratio

After the sheet was pulled out using each sample, the ratio of the length of the end of the sanitary tissue held by the take-out section 3 in the range of 5mm to 39mm, which is a preferable projection amount, was calculated as the appropriate exposed portion ratio. This is because if the thickness is 4mm or less, the user is difficult to hold the sheet with his fingers, and if the thickness is 40mm or more, the sheet protrudes when the small lid 22 is closed.

(6) Cross resistance

When the sheet was pulled out using each sample, the average value of the forces required when the sheet was pulled out, which were measured using a digital load cell (manufactured by Emmenda, Japan: model DS2-200N), was calculated as the cross resistance.

The results of the test are shown in table 1.

[ Table 1]

[ evaluation ]

Comparing examples 1 to 3 in table 1, it is understood that the removal performance of the removal portion 3 is greatly changed by changing the hardness. In particular, as the hardness is increased, the number of continuous passes and the appropriate exposed portion ratio are improved, and the length variation of the exposed portion is also reduced, but the number of passes is reduced, and the resistance value of the cross portion is also increased.

This is presumably because the resistance to the sheet becomes excessively large due to the increase in hardness.

[ test 2. variation in Performance due to variation in the mixing ratio of elastomer and PE in the take-out section ]

Next, the results of the same tests as in test 1 performed on the samples corresponding to examples 4 and 5 are shown in table 2.

[ Table 2]

[ evaluation ]

Comparing examples 1 and 4 in table 2, it is understood that the resistance value of the cross portion hardly changes and the number of consecutive times can be improved by increasing the proportion of PE contained in the take-out portion 3.

This is presumably because the sheet is easily broken by increasing the resistance applied to the sheet.

Further, it is understood that the number of falls is improved by increasing the proportion of PE contained in the take-out section 3 in comparison with examples 1, 4 and 5.

[ Effect of the embodiment ]

According to the hygienic tissue paper storage container 100 of the present embodiment, the removal portion 3 is provided by mixing the elastic body and PE, and the hardness of the removal portion 3 can be finely adjusted by changing the mixing ratio of the elastic body and PE, so that the removal performance can be adjusted.

In general, when coloring the elastomer, since the elastomer is mixed with a substance obtained by mixing a pigment into PE, it is possible to easily adjust the extraction performance of the extraction portion 3 by changing the mixing ratio without requiring additional time and cost for adding a process or the like or changing a material.

In particular, by changing the mixing ratio of the elastomer and PE from 100: 5 to 100: 7.5 to 100: 10, the degree of difficulty in dropping the sheet and the degree of difficulty in continuation can be improved.

Further, unlike the case where the hardness of the takeout section 3 is changed by changing the kind of elastomer used as a material, even if the perforation line of the sanitary tissue paper is adjusted to be easily broken, the change in the resistance value of the takeout hole 33 (corresponding to the cross portion in the embodiment) can be suppressed, and the ease of taking out the sanitary tissue paper storage container 100 can be kept substantially constant.

Industrial applicability of the invention
