Description

The present invention relates to a sanitary tissue storage container for storing sanitary tissue such as wet wipes and wet tissues.

2. Description of the Related Art Conventionally, there has been known a sanitary tissue paper storage container for storing sanitary tissue paper for wiping house floors, toilets, the human body, etc. (see, for example, Patent Document 1).
This sanitary tissue storage container is designed to store multiple sheets of sanitary tissue in a stacked manner, and the sanitary tissue can be removed and used by opening the lid of the container and removing the sheets in order, starting from the top.

Also known as a sanitary tissue paper storage container is one in which a roll of sanitary tissue paper is stored inside a container body having an opening, and a lid body attached to cover the opening of the container body is provided with a removal section having a removal hole for pulling out the sanitary tissue paper, and resistance is applied to the sanitary tissue paper as it is pulled out from the removal hole, causing it to be torn off at perforations provided in the sanitary tissue paper (see, for example, Patent Document 2).
The roll of sanitary tissue paper stored in this sanitary tissue paper storage container is, for example, pulled out from the center of the roll and cut off one sheet at a time for use.

JP 2007-112458 A JP 2019-112130 A

However, when multiple sheets of sanitary tissue paper are stored in a stacked manner, as in the sanitary tissue paper storage container of Patent Document 1 above, there is a problem that the medicinal solution impregnated in the sanitary tissue paper is prone to evaporate and the sanitary tissue paper tends to dry out relatively easily.
In contrast, storing rolls of sanitary tissue paper, as in the sanitary tissue paper storage container of Patent Document 2 above, makes it less likely for the medicinal solution impregnated in the sanitary tissue paper to evaporate than storing multiple sheets of sanitary tissue paper stacked together.However, because the rolls of sanitary tissue paper stored in this sanitary tissue paper storage container are designed to be separated one sheet at a time, it is difficult to pull out multiple sheets of sanitary tissue paper in length, and there is a problem that the sanitary tissue paper pulled out to the desired length cannot be folded and used.

The object of the present invention is to provide a sanitary tissue paper storage container that allows convenient removal and use of rolled sanitary tissue paper.

In order to solve the above problems, the invention described in claim 1 is:

[Configuration of the embodiment]
{overall structure}
The sanitary tissue paper storage container 100 of this embodiment, as shown in Figures 1 to 7, includes a container body 10 having an opening 10c at the top for storing rolled sanitary tissue paper P impregnated with liquid such as water or a chemical solution, a lid body 20 that is rotatably provided on the rear surface 10a side of the container body 10 and allows the opening 10c to be opened and closed, and a retaining shaft 60 that is removably hung between opposing inner surfaces within the container body 10.
As shown in Figures 6 and 7, this holding shaft 60 is inserted into the hollow portion at the center of the axis of the roll of sanitary tissue paper P and is hung within the container body 10 to hold the roll of sanitary tissue paper P.

[Container body and lid body]
The sanitary tissue paper storage container 100 is a housing-like container that stores rolls of sanitary tissue paper P, such as wet wipes or wet tissues, inside the container body 10 with the lid 20 closed.
The container body 10 is formed in a bottomed rectangular cylindrical shape, with a bottom 10d provided on its lower surface and an opening 10c provided on its upper surface.
The lid body 20 has a shape that allows it to seal the container body 10, as described below.
With the lid 20 open, the sanitary tissue paper P can be removed from the opening 10c of the container body 10.
The container body 10 and the lid body 20 are molded from resins such as PP (polypropylene), ABS (acrylonitrile butadiene styrene), PE (polyethylene), and a mixture of PP and PE using common manufacturing methods such as blow molding and injection molding (cold runner, hot runner).
The sanitary tissue paper storage container 100, which is composed of the container body 10 and the lid 20, is formed to have dimensions of preferably 90 mm to 150 mm, more preferably 100 mm to 120 mm in the front-rear direction, preferably 100 mm to 200 mm, more preferably 140 mm to 160 mm in the left-right direction, and preferably 60 mm to 130 mm, more preferably 90 mm to 110 mm in the up-down direction. The thickness of each surface is preferably 0.5 mm to 3 mm, more preferably 1 mm to 2 mm.
This size and thickness will achieve sufficient strength for practical use and will allow the sanitary tissue paper P to be suitably stored.

(Rotating part)
A container hinge portion 11 is formed near the opening 10c of the rear surface portion 10a of the container body 10, and a lid hinge portion 21 is formed on the rear surface side of the lid body 20.
In this storage container, a lid hinge portion 21 is sandwiched between a pair of container hinge portions 11 and pivotally attached.
For example, by engaging the shaft protrusion of the lid hinge portion 21 into the shaft hole of the container hinge portion 11 and assembling the container hinge portion 11 and the lid hinge portion 21, a rotating portion 50 is formed in which the container hinge portion 11 and the lid hinge portion 21 are connected.
The lid body 20 is disposed rotatably relative to the container body 10 via the rotating portion 50 .

(Using member)
Between the container body 10 and the lid body 20 and on the inside of the storage container near the rotating portion 50, a biasing member 30, which is, for example, a resin leaf spring, is disposed.
Specifically, the biasing member 30 is arranged in the sanitary tissue paper storage container 100 such that one end of the biasing member 30 is fixed to a spring fixing portion 31 provided near the opening 10c on the inside of the rear portion 10a of the container body 10, and the other end of the biasing member 30 is fixed to a spring fixing portion 32 provided on the inside of the lid body 20.
In addition, a protrusion 40 protruding toward the front portion 10b of the container body 10 is provided at approximately the center of the width of the rear portion 10a of the container body 10, and a spring fixing portion 31 is provided at the upper end portion of the protrusion 40.
The biasing member 30 biases the lid body 20 in a direction away from the container body 10, whereby the lid body 20 is pushed up so as to rotate about the rotating portion 50 as an axis, thereby opening the opening 10c.

(Engagement part/Lock part)
An engagement portion 13 is formed near the opening 10c on the front portion 10b of the container body 10, and a locking portion 23 is formed on the front side of the lid 20.
When the front side of the lid body 20 comes into contact with the front portion 10b of the container body 10, the engagement portion 13 engages with the locking portion 23, thereby engaging the lid body 20 with the container body 10 side and closing the opening 10c.

In addition, a clamping portion 12 that protrudes forward is provided on the front portion 10b of the container body 10 near the engagement portion 13, and an engagement release member 14 is axially supported and arranged on the clamping portion 12 so that its position can be changed.
When the disengaging member 14 and the clamping portion 12 are clamped, one end 14a of the disengaging member 14 swings in a direction approaching the clamping portion 12. When the position of the disengaging member 14 is changed so as to swing it in this manner, the other end 14b of the disengaging member 14 pushes up the push-up protrusion 24 of the lid 20, and the engagement between the locking portion 23 and the engaging portion 13 is released.
In other words, when the disengaging member 14 is clamped against the clamping portion 12 and the disengaging member 14 is swung to disengage the locking portion 23 from the engaging portion 13, the lid body 20 is pushed up and opened by the biasing force of the biasing member 30.

In addition, a groove 5 is formed on the peripheral portion 4 of the opening 10c of the container body 10, into which the peripheral portion 3 (inner ring) of the lid body 20 fits when the lid body 20 is closed on the container body 10.
When the peripheral portion 3 of the lid 20 is fitted into the groove 5 of the peripheral portion 4 of the container body 10 , the outer surface of the peripheral portion 3 is in close contact with the inner surface of the groove 5 .
Then, when the lid body 20 is closed to close the opening 10c of the container body 10 and the peripheral portion 3 of the lid body 20 is fitted into the groove portion 5, the inner surface of the groove portion 5 and the outer surface of the peripheral portion 3 are tightly attached around the entire circumference of the opening 10c, thereby sealing the space between the container body 10 and the lid body 20, thereby ensuring the airtightness of the sanitary tissue paper storage container 100.

In particular, it is preferable that the peripheral portion 3, which functions as an inner ring and is fitted into the groove portion 5, has flexibility. The higher the flexibility of the peripheral portion 3, the better the fit between the groove portion 5 and the peripheral portion 3, and the higher the airtightness of the container.
The dimension by which the peripheral portion 3 fits into the groove portion 5 is preferably 1.0 mm to 8.0 mm, and more preferably 3.0 mm to 6.0 mm.

In addition, it is preferable that a lubricant (e.g., silicon oil) is applied to the groove 5 into which the peripheral portion 3 (inner ring) of the lid body 20 fits. If a lubricant is applied to the groove 5, the peripheral portion 3 can be easily removed from the groove 5, so that the urging force of the urging member 30 can easily open the lid body 20.
Furthermore, if a lubricant is applied to the groove 5, the lubricant will fill the gap between the groove 5 and the rim 3, improving the adhesion between the groove 5 and the rim 3 and making the container more airtight.

[Holding shaft]
The retaining shaft 60 has a structure in which a relatively thin second shaft body 62 is inserted into a relatively thick first shaft body 61, and an elastic member such as a coil spring is disposed between the first shaft body 61 and the second shaft body 62 inside the retaining shaft 60. The retaining shaft 60 configured in this manner is capable of expanding and contracting in the longitudinal direction.
This holding shaft 60 has protrusions 60a on both ends, and the holding shaft 60 is adapted to be spanned between the inner surfaces of the container body 10 with the protrusions 60a abutting against opposing inner surfaces within the container body 10.
Specifically, a locking recess 10h is provided on the inner surface of the left side surface 10L and the inner surface of the right side surface 10R of the container body 10, and when the retaining shaft 60 is extended, the protrusions 60a at both ends are inserted into and locked into the locking recesses 10h, so that the retaining shaft 60 is suspended within the container body 10.
Furthermore, the holding shaft 60 suspended within the container body 10 is disposed approximately parallel to the bottom surface (bottom portion 10d) of the container body 10.

Then, as shown in Figures 6 and 7, the holding shaft 60 is inserted into the hollow portion at the center of the axis of the roll of sanitary tissue paper P, and the holding shaft 60 is hung within the container body 10, thereby allowing the roll of sanitary tissue paper P to be stored in the sanitary tissue paper storage container 100 (container body 10).
In particular, since the holding shaft 60 rotatably holds the rolled sanitary tissue paper P, the rolled sanitary tissue paper P can be conveniently pulled out from within the container body 10. In the sanitary tissue paper storage container 100 of this embodiment, the sanitary tissue paper P is pulled out toward the front side of the container.
In addition, the roll of sanitary thin paper P has perforations P1 at predetermined intervals, so that the user can pull out the sanitary thin paper P from the container and cut off the sanitary thin paper P at any desired perforation P1, thereby allowing the user to take out the sanitary thin paper P of the desired length from the sanitary thin paper storage container 100 and use it.
The roll-shaped sanitary thin paper P pulled out from inside the container body 10 can be sandwiched between the lid body 20 and the container body 10, thereby applying frictional resistance to the sanitary thin paper P. For example, by applying frictional resistance by sandwiching the pulled-out sanitary thin paper P near the perforation P1, the sanitary thin paper P can be easily separated, and the sanitary thin paper P can be removed from the sanitary thin paper storage container 100 and used.

<Operation of the embodiment>
In the above-mentioned sanitary tissue paper storage container 100, the holding shaft 60 can be inserted through the hollow portion of the axis of the roll of sanitary tissue paper P, and the holding shaft 60 can be hung within the container body 10, so that the roll of sanitary tissue paper P can be stored in the sanitary tissue paper storage container 100.
The holding shaft 60 rotatably holds the roll of sanitary tissue paper P, so that the roll of sanitary tissue paper P can be conveniently pulled out from within the container body 10, and the roll of sanitary tissue paper P has perforations P1 at predetermined intervals, so that the sanitary tissue paper P can be cut off at the desired length, allowing the user to remove and use the sanitary tissue paper P of the desired length from the sanitary tissue paper storage container 100.
For example, when wiping off a small amount of dirt, one or two sheets of sanitary tissue paper P can be taken out by pulling out one or two perforations.
Also, for example, when firmly wiping off stubborn dirt, three or more sheets of sanitary tissue paper P can be pulled out by pulling out three or more perforations, and three or more sheets of sanitary tissue paper P can be taken out and used.
In other words, when thicker sanitary tissue paper P is required, a longer piece of sanitary tissue paper P can be taken out and folded for use.

Effects of the embodiment
According to this embodiment, in a sanitary tissue paper storage container 100 comprising a container body 10 having an opening 10c for removing the sanitary tissue paper P impregnated with liquid stored therein, and a lid body 20 for allowing the opening 10c of the container body 10 to be opened and closed freely and capable of sealing the container body 10c, the container body 10 is provided with a holding shaft 60 that is removably suspended between the opposing inner surfaces, and the holding shaft 60 is suspended within the container body 10 while being inserted through the hollow portion of the axis of the roll of the roll of sanitary tissue paper P, and is configured to rotatably hold the roll of sanitary tissue paper P.

The sanitary tissue paper storage container 100 of this embodiment has such a configuration, so that the roll of sanitary tissue paper P can be conveniently pulled out from within the container body 10.
When wiping off a small amount of dirt, the sanitary tissue paper P can be pulled out and separated in a short length, and used as a thin sanitary tissue paper P.
In addition, when scrubbing off stubborn dirt, a long piece of sanitary tissue paper P can be pulled out, cut off, and folded up to be used as thick sanitary tissue paper P.

In particular, this sanitary tissue paper storage container 100 is designed to store rolled sanitary tissue paper P impregnated with a medicinal solution, which makes it less likely for the medicinal solution to evaporate and for the sanitary tissue paper P to dry out than when multiple sheets of sanitary tissue paper impregnated with the medicinal solution are stored in a stack, making it suitable for use as a container for storing wet-type sanitary tissue paper P.

<Comparative test>
Next, the results of a comparison of the ease of evaporation of medicinal liquid from sanitary tissue paper will be described.
As the sanitary tissue paper storage container 100, a container having the shape shown in Figs. 1 and 2 and including a container body 10 and a lid 20 made of PP was prepared.
The sanitary tissue paper used was 2-ply water-disintegrable paper with a ratio of NBKP/LBKP=40/60 and a basis weight of 86 g/m ² , which was soaked in 200% of the cleaning solution used by our company.
Sanitary tissue paper was stored in this sanitary tissue paper storage container 100 under the conditions of Example 1 and Comparative Example 1 below, and the amount of chemical solution evaporated from the sanitary tissue paper and reduced was measured.

In Example 1, the above water-disintegrable paper was cut to a width of 130 mm and a length of 800 mm, perforations were made every 100 mm in the longitudinal direction, and the cut paper was wound around a holding shaft 60. The holding shaft 60 was then hung within the container body 10, and a sample of sanitary tissue paper was stored in the sanitary tissue paper storage container 100.
In Comparative Example 1, eight sheets of the water-disintegrable paper were cut to a width of 130 mm and a length of 100 mm, stacked, and placed on the bottom of the container body 10 to store a sample of sanitary tissue paper in the sanitary tissue paper storage container 100. In this Comparative Example 1, the retaining shaft 60 was not used.

After measuring the weight of the sanitary tissue paper storage container 100 containing the sample of Example 1 and the sanitary tissue paper storage container 100 containing the sample of Comparison Example 1, each storage container was stored in a constant temperature bath at 60°C, and the weight was measured every specified time (here, 1 hour) to measure the reduction rate of the chemical solution.
In Example 1, the rate of decrease after 1 hour was 0.1%, the rate of decrease after 2 hours was 0.3%, and the rate of decrease after 3 hours was 0.4%.
In Comparative Example 1, the rate of decrease after 1 hour was 0.2%, the rate of decrease after 2 hours was 0.4%, and the rate of decrease after 3 hours was 0.7%.
Thus, it was confirmed that the reduction rate of the chemical solution was higher in Comparative Example 1 than in Example 1.
In other words, it was confirmed that storing rolled sanitary tissue paper in the sanitary tissue paper storage container 100 makes it less likely for the medicinal liquid impregnated in the sanitary tissue paper to evaporate than storing multiple sheets of sanitary tissue paper stacked together.

As described above, the sanitary tissue paper storage container 100 of this embodiment can suitably store wet-type sanitary tissue paper P in roll form.
This sanitary tissue paper storage container 100 rotatably holds the roll of sanitary tissue paper P by means of a holding shaft 60, so that the roll of sanitary tissue paper P can be conveniently pulled out from within the container, and the sanitary tissue paper P can be pulled out to the desired length and then cut off at the perforations P1 for use.

The application of the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the present invention.
