Description

  The present invention relates to a product in which sheet rolls such as kitchen paper and toilet paper wound in a roll shape are stored in a storage box.

For example, most kitchen paper is provided in a rolled state in a cylindrical paper tube roll. When a user uses it, a fixed holder purchased separately is fixed to the wall, and a roll sheet is attached to this. For example, as shown in Patent Document 1 below, purchase what is provided in a state of being stored in a paper box, unwind it by a required length, and use it after unwinding it. I am doing so.
And in the product provided by being stored in the conventional storage box, as disclosed in the following Patent Document 1, the entire upper surface of the storage box is configured to have a hinge lid shape and wide open when used. It is common.
This is because the position of the tail edge of the sheet roll in the storage box is not fixed in the product provided in the storage box, so that the edge of the sheet roll can be grasped by widening the opening during use. One of the reasons is the problem that must be made.
JP 2005-280806 A

However, kitchen paper, toilet paper, and the like are required to be sanitary, and therefore it is often preferable that the opening is not wide.
Therefore, it is better for the take-out port to have a small opening area such as a slit. However, in the conventional product, the position of the tail edge of the sheet roll cannot be recognized from the outside as described above, and the tail end portion is taken out. Since there is no way to rotate the sheet roll in the storage box from the outside in order to position it in the vicinity, as a result, there is no choice but to open the outlet widely.
It is also conceivable to form a hole on the outer surface of the storage box that can contact the peripheral surface of the sheet roll, but it is not easy to rotate the sheet roll from the outside due to friction between the storage box and the peripheral surface of the sheet roll. Absent.
In addition, since the conventional product is in contact with the inner surface of the box and the peripheral surface of the sheet roll, the portions are rubbed with each other as they are pulled out, causing problems such as generation of paper dust and unintentional breakage.
Accordingly, a main problem of the present invention is to provide a sheet roll storage product that is capable of designing a take-out port that is less likely to generate paper dust and less likely to enter dust, and that has excellent sheet roll take-out properties. .

The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
In a cylindrical storage box having a structure in which both end openings of the cylindrical main body are sealed by a lid member, a long sheet roll wound around a tube shaft has its axial direction in the axial center of the cylindrical storage box A sheet roll storage product stored along
A take-out port or a forming part for pulling out the leading end of the sheet roll is provided along the longitudinal direction of the main body part, and a widened finger insertion part is formed at the center of the take-out port or the forming part. And
A protrusion is formed on the inner surface side of the storage box of the lid member toward the inner surface of the storage box, and the protrusion enters the tube shaft of the sheet roll, so that the sheet roll is in the main body, and its peripheral surface is It is rotatably supported without contacting the inner surface of the main body,
A sheet roll storage product characterized by that.

(Function and effect)
When the sheet roll is stored in the storage box, it is generally performed that the axial center direction is stored along the longitudinal direction of the storage box. Since the unwinding direction of the sheet in the sheet roll is a tangential direction, the sheet can be smoothly fed out by providing an outlet or a forming portion for pulling out the leading end of the sheet roll in the longitudinal direction of the main body of the storage box. .
In the present invention, the sheet roll can be rotated and not in contact with the inner surface of the main body by fitting the protrusions on the inner surface of the lid member located on both sides in the longitudinal direction of the storage box into the paper tube of the sheet roll. I am going to support it.
Therefore, the inner surface of the main body and the peripheral surface of the sheet roll are not rubbed, and the risk of paper dust generation and breakage is significantly reduced.

Furthermore, since the sheet roll is supported only at both ends as described above and there is no friction with the main body, the force required for rotation is less than that of the conventional product. In the present invention, by forming a finger insertion hole or the like in the outlet of the main body, the finger is inserted from here to access the peripheral surface of the sheet roll, the sheet roll is rotated, and the sheet roll is moved to the outlet position. The tail edge can be positioned. In this way, the inner sheet roll can be rotated from the outside of the storage box simply and without excessive force, so there is no need to unnecessarily widen the outlet, and the outlet can be formed in a slit shape. It is possible to adopt an outlet shape in which dust and the like are difficult to enter from the outside.
In particular, when employed as a kitchen roll or the like, since it is assumed that it is used in a kitchen where water, dirt, etc. are likely to adhere, it is possible to effectively enjoy the merit of making the outlet in the present invention into a slit shape.

  In addition, the front-back and up-down directions in the present invention are based on the outlet for pulling out the leading end portion of the sheet roll or the portion where the forming portion is formed, and are limited to the direction when the product is used. It is not a thing. In addition, the term “formation part” means a part that is opened by the user at the first use, and as long as it is processed to prepare openings such as perforations, Including those that do not require any processing (the same shall apply hereinafter).

<Invention of Claim 2>
2. The sheet roll storage product according to claim 1, wherein the narrowed protrusion shape of the lid member is a cone, a polygonal pyramid, or a substantially hemispherical shape.

(Function and effect)
The rotation of the sheet roll in the storage box becomes good. In particular, a cone or a substantially radial shape requires less force for rotation, and a polygonal cone eliminates the possibility of unintentionally rotating the sheet roll in the storage box to loosen the sheet.

<Invention of Claim 3>
The sheet roll storage product according to claim 1 or 2, wherein a pressing piece continuous from the outlet is formed at a position corresponding to the finger insertion portion.

(Function and effect)
It becomes easy to cut the sheet roll.

<Invention of Claim 4>
The sheet roll storage product according to any one of claims 1 to 3, wherein the lid member is detachable from the main body.

(Function and effect)
The sheet roll can be taken out from the storage box. Therefore, for example, when a rotation failure of the sheet roll, loose winding, or the like occurs, or when it is desired to use a large amount, it can be used by taking it out from the storage box and appropriately storing it in the storage box again. It becomes like this.

<Invention of Claim 5>
The sheet roll storage product according to claim 4, wherein a knob portion is formed on an outer surface side of the lid member.

(Function and effect)
The lid member can be easily attached and detached.

  As described above, according to the present invention, it is possible to design a take-out outlet that is less likely to generate paper dust and difficult to enter dust, and the sheet roll storage product is excellent in sheet roll take-out performance. Benefits are provided.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
<First form>
FIG. 1 shows an unused state of a sheet roll product X1 in which a sheet roll is stored in a storage box, FIG. 2 shows the inside thereof, and FIG. 3 shows a used state.
As shown in FIG. 1, the storage box 1 of this embodiment has a cylindrical shape in an assembled state, and has a cylindrical main body portion 10 and lid members 20 and 20 that seal the openings at both ends, respectively. is doing.
As shown in FIG. 2, the sheet roll 40 is stored in the inner space of the storage box 1 so that the axial direction is along the longitudinal direction of the storage box 1.

Here, the sheet roll 40 of the present invention is not particularly limited, but is preferably a fiber assembly sheet such as paper or nonwoven fabric, and particularly has a winding density (roll diameter per unit winding length: winding length). The density determined as the value divided by the roll cross-sectional area is preferably 0.20 to 0.78 m / cm ² . If this range is exceeded, the sheet roll 40 becomes too hard and heavy, and the smoothness of sheet feeding may be impaired. On the other hand, if it is smaller than this range, the sheet roll 40 becomes too loose and light. Therefore, even if the leading edge of the sheet is fed forward, the leading edge may return to the original direction, that is, backward. There is. Although the illustrated example has the tube core 41, it may be without a core. Further, in the sheet roll 40 of the present invention, it is preferable that the perforation for separation is formed along the width direction at a predetermined interval in the longitudinal direction, but there is no such perforation and the length is arbitrary. A type that breaks the sheet may be used. (In the figure, the tube core of the sheet roll is denoted by reference numeral 41 and the winding portion is denoted by reference numeral 42.)

  On the other hand, a perforation 30 as an outlet forming portion is formed along the longitudinal direction on the longitudinal surface of the main body 10 in the storage box 1, that is, on the peripheral surface of the cylindrical storage box 1 of this embodiment. ing. In particular, the perforated line 30 in the illustrated example is arranged so that two perforated lines are juxtaposed and a slit-shaped opening is formed at the time of tearing. In use, the perforation line 30 is cleaved to form a slit-shaped outlet 31, and the sheet roll 40 is appropriately drawn out from the outlet and cut for use.

Further, a central portion of the outlet forming portion 30 has a curved portion 30W where the perforation line 30 is curved in one direction so that the opening is widened at the time of tearing as shown in FIG. It is configured. The widened portion serves as a finger insertion portion, and a finger can be put into the inner surface of the storage box from the finger insertion portion and touch the sheet roll peripheral surface.
In this embodiment, the outlet is formed by the cleavage of the perforation line 30. Of course, the perforation 30 can be omitted by opening this portion in advance.

On the other hand, as can be understood from the internal view shown in FIG. 2, the sheet roll product X1 has a characteristic feature that the box inner surface side of the lid members 20 and 20 protrudes in a conical shape, and the protruding end is a sheet. By entering the tube core 41 from the end face side of the roll 40, the peripheral surface of the sheet roll 40 is supported rotatably in a non-contact state with respect to the main body portion inner surface 10i of the storage box 1 (lid member). Is indicated by reference numeral 21 in the figure).
More specifically, the lid members 20, 20 have a cylindrical portion 22 having a slightly smaller diameter than the inner periphery of the main body portion 10, and continuously protrude from the edge of the cylindrical portion 22 in a conical shape on one side surface. It has an outer shape on which the protruding portion 21 is formed. In addition, the protrusion part 21 may be formed with the level | step difference from the edge of a cylindrical part.
Needless to say, the distance between the protrusion tips of the lid members 20 and 20 is made narrower than the width of the tube core 41 of the sheet roll 40 to be stored.

  In addition, the protrusions may have a planar vertex angle θ of 30 to 150 degrees, preferably 75 to 105 degrees formed by a cross section passing through a perpendicular from the vertex. If the angle is excessively small (because θ is garbled in the drawing), it is necessary to widen the carton width. If the angle is large, the sheet roll cannot be stably supported and does not rotate smoothly.

Here, in the sheet roll product X1, the shortest distance from the imaginary line connecting the apexes of the conical portions 21 and 21 at both ends to the inner surface of the storage box is longer than the distance from the axis of the sheet roll to the outer peripheral surface thereof. The inner diameter of the storage box and the diameter of the lid member are set. As a result, when the sheet roll 41 is supported between the protrusions 21 and 21 at both ends of the storage, the outer peripheral surface thereof is rotatably supported without being in contact with the inner surface of the storage box.
It should be noted that the apexes of the protrusions 21 of the lid members 20 and 20 at both ends are preferably positioned at the axial center of the cylindrical main body 10.

On the other hand, the lid members 20 and 20 are preferably formed so as to be detachable with respect to the main body portion 10 so that the sheet rolls 40 accommodated therein can be refilled.
And in this sheet roll product X1 of the example of illustration which enables this attachment or detachment, a spiral part is each formed in the outer peripheral surface of the cylindrical part 22 of the cover members 20 and 20, and the inner surface of the main-body part vicinity of these, It is made to be detachably locked by the spiral stop function.

  In addition, when making the lid members 20 and 20 detachable, a known latching means can be employ | adopted. For example, an elastic O-ring is arranged on the outer periphery of the cylindrical portion of the lid member 20 and locked by press contact with the inner circumference of the storage box (shown in the shape example of another lid member shown in FIG. The O-ring is indicated by reference numeral 50), and locking means or the like in which an annular convex portion is formed on the inner peripheral surface of the storage box corresponding to the outer periphery of the cylindrical portion can be employed.

  When forming the locking means, if a plurality of annular protrusions or O-rings are provided or spiral, the position of the lid member relative to the storage box can be adjusted, and the distance between the both-end lid members 20 and 20 can be adjusted. Become. Therefore, if the said latching means is employ | adopted, the versatility with respect to the sheet roll 40 from which paper width differs will increase.

  The lid members 20 and 20 are provided with a plurality of finger insertion holes 24 and 24 on the outer surface side of the end face 23 of the storage box 1 (see FIG. In the example shown, two) are provided. Preferably, three finger holes are arranged so that each hole is a vertex of an equilateral triangle. In this arrangement mode, the lid member can be rotated with an equal force (a configuration in which three finger insertion holes are arranged is shown in FIG. 6). Therefore, the lid member can be easily locked and detached by spiral fastening to the storage box.

  On the other hand, in order to store the sheet roll 40 in the storage box 1, after sealing one opening of the main body 10 with the lid member 20, the sheet roll 40 is inserted from the other opening, and the other opening is also opened. Sealed with the lid member 20. By this operation, the sheet roll 40 is accommodated in the storage box 1 and supported rotatably.

  And in sheet roll product X1 of this form which takes the above-mentioned composition, in use, after separating perforation 30 and forming outlet 31 as shown in Drawing 3, it is the tip of sheet roll 10 from outlet 31 , The finger is inserted from the widened finger insertion portion 32 formed in the central portion of the outlet 31 and rotated so as to rub the peripheral surface of the sheet roll 10 supported inside, thereby adjusting the tail edge. It is positioned in the vicinity of the outlet, and is further used by being pulled out of the outlet 31 and exposed.

  Here, in the storage box 1 of this embodiment, the perforation 30 is curved so that the finger insertion portion 32 is formed. With this configuration, when the sewing machine line is cleaved to form the outlet 31, the widened finger insertion portion 32 as shown in FIG. 3 is formed, and the portion that sealed the finger insertion portion is It becomes the protruding edge piece 33. The protruding edge piece 33 can function as a holding piece 33 that presses against the sheet roll, and is used to lock the rotation by pressing against the sheet roll as necessary.

In the above-described sheet roll product X1 of the present invention, since the sheet roll 40 is supported without contacting the inner surface 10i of the storage box 1, the sheet roll is contained in the storage box with a weak force that rubs the peripheral surface of the sheet roll. Can be easily rotated.
And even if a sheet roll rotates with drawer | drawing-out, since the inner side of a storage box and a sheet roll peripheral surface are not in contact, paper dust will not generate | occur | produce by rubbing.
In addition, the rotation is smooth, and the effect of being excellent in pulling out is obtained.
Furthermore, at the time of cutting, by pressing the holding piece with a finger, the rotation of the sheet roll accompanying the drawer can be locked and cut without touching the sheet roll.

  On the other hand, in the present invention, the material of the storage box is not particularly limited. The lid member and the main body can be made of the same material, or can be made of different materials. As a specific example of the material, if the storage box is disposable, it is preferably made of paper, and only the storage box is used repeatedly, and if the sheet roll can be refilled, it is formed of a plastic material or the like. Is good.

<Other forms>
In the first embodiment, the shape of the inner side of the storage box of the lid member 20 is a conical shape. However, in the present invention, the shape is not limited to this, and for example, a pyramid shape or a substantially hemispherical shape as shown in FIG. (The protrusion 21 in FIG. 4 is an octagonal pyramid).

  Moreover, although the main-body part 10 was made into the column shape in the 1st form, not only this but a square tube shape may be sufficient. In this case, not only a rectangular parallelepiped shape but also an appropriate polygonal cylindrical shape such as a hexagonal cylindrical shape can be adopted. In addition, if the main body is formed in a rectangular tube shape in this way, the cylindrical portion 22 of the lid member 20 can be appropriately changed to the same shape corresponding to fit into the rectangular tube-shaped opening. Good.

  Further, in the first embodiment, the two oval holes 24, 24 are arranged side by side to form the knob, but the present invention is not limited to this. If an appropriate number, for example, about 2 to 5, is provided, the purpose of this knob can be achieved. Further, the knob is not limited to the hole, and a knob protrusion 25 or a knob can be provided as shown in FIG. However, it is desirable to form the holes because the width of the storage box 10 does not increase.

  The present invention can be suitably used for sheet roll products represented by kitchen paper and toilet paper.
