Description

  The present invention relates to a paper dispenser.

  Conventionally, after a paper sheet is pulled out from a take-out port of a housing that accommodates a long paper sheet (for example, a roll towel) to a desired length, the paper sheet is attached in the vicinity of the cut-out blade There is known a paper dispenser capable of cutting a paper sheet by pressing it against the surface and tearing it along the width direction (see, for example, Patent Document 1).

  Here, for example, when the user puts out a finger toward the cut end (tip portion) of the paper sheet for the purpose of using the paper sheet, the presence of the cutting blade may be a blind spot and may be difficult to see, There is a risk of fingers touching the blade edge. If the user's fingers come into contact with the cutting edge, the user's fingers may be injured. Therefore, ensuring the safety of the user is an important issue.

The technology that protects fingers from the blade edge is disclosed as follows. In the wrap film storage case, the tip of the top cover (paper cover piece) with a metal saw blade for cutting the film is attached to the top of the saw blade. A technique for extending between the valleys is disclosed (for example, see Patent Document 2).
When the technology according to Patent Document 2 is applied to, for example, the paper dispenser according to Patent Document 1, the length of the protruding portion of the cutting blade is shortened, and the user's fingers are not deeply bitten. A certain effect can be expected in terms of securing.

JP 2002-283280 A JP 2005-187015 A

However, even if the length of the protruding portion of the cutting blade is shortened, the contact with the blade edge cannot be prevented, and there is still a possibility of damaging the finger.
Further, when the length of the protruding portion of the cutting blade is shortened, the sharpness at the time of cutting the paper sheet is lowered, so that a force is required for the cutting operation and the cut edge of the paper sheet may become dirty.

  An object of the present invention is to provide a paper dispenser that can ensure the safety of the user and can easily cut out a paper sheet with a clean cut end.

The invention described in claim 1 is made in order to achieve the above object, and draws out the paper sheet to a desired length from an outlet provided in a casing that accommodates the long paper sheet. Then, in a paper dispenser capable of cutting out the paper sheet by a cutting part attached in the vicinity of the outlet,

The cutouts, as its distal end is positioned inside the housing, Rutotomoni disposed below end portion of the front Kifutatai that make up the joint, the lid is in the closed state When the lid is in an open state, the tip is disposed so that the tip is directed upward.
A sandpaper having a grain size of abrasive fine powder of # 100 to # 180 is attached to the cut portion so as to cover the tip portion.

  According to a second aspect of the present invention, in the paper dispenser according to the first aspect, the cut-out portion is formed by a direction from the front end to the other end and the paper sheet pressed against the front end. It is attached so that the angle α may be 45 ° ≦ α ≦ 70 °.

  According to the first aspect of the present invention, since the sandpaper is attached so as to cover the tip of the cut portion, there is no possibility of damaging the user's finger as when using the cut blade. Safety can be ensured. In addition, the cut edge of the paper sheet is cleaner and smoother than when the cutting blade is used, and a high-grade and soft impression can be given to the user. Furthermore, compared with the case where a metal cutting blade is used, the cutting portion 5 to which the sandpaper 6 is attached can be made at a low cost and is easy to return naturally, so it is good for the environment. Further, the user can cut out the paper sheet with a small force, and even a child or an elderly person can easily cut out the paper sheet. In the present invention, to pull out a paper sheet to a desired length means that the paper sheet is pulled out by grasping with a finger, or the presence of a user is detected using an optical sensor or the like, and the paper sheet is automatically pulled out. To pull out.

FIG. It is the figure shown about the modification of the attachment position of the cut-out part.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a roll towel dispenser containing a roll towel will be described as an example of the paper dispenser.

As shown in FIGS. 1 and 2, the roll towel dispenser 100 includes a storage body 11 that supports a long paper sheet (roll towel P), and one on each of the left and right side surfaces 11 a and 11 a of the storage body 11. A roll towel P can be accommodated in a housing 1 having a lid 12 that is connected to the hinge portions 2 and 2 so as to be opened and closed. The rear surface 11b of the storage body 11 is fixed to a wall surface such as a kitchen or a washroom. The lid 12 can be opened and closed in the front direction (arrow direction X in the figure) by rotating about the hinge portion 2 (see FIG. 2). The user can freely load the roll towel P into the storage body 11 or remove the roll towel P from the storage body 11 by opening the lid body 12 in the front direction.
An outlet 3 is provided at the joint of the lower surface 11 c of the storage body 11 and the lower end portion 12 a of the lid body 12. The user can draw out the roll towel P accommodated in the housing 1 through the outlet 3.

As shown in FIG. 2, the storage body 11 rotates a paper roll towel P wound in a roll shape by means of paper support portions 4, 4 provided one at the center of the left and right side surfaces 11 a, 11 a. Support as possible.
The tip portion P1 of the roll towel P supported by the paper support unit 4 is drawn out of the housing 1 through the outlet 3 provided on the lower surface of the housing 1.
A cutout portion 5 for cutting out the roll towel P is attached to the lower end portion 12 a of the lid body 12. The user can cut the roll towel P by pressing the desired position of the drawn roll towel P against the cutout portion 5 and pulling it upward while the lid 12 is closed (see FIG. 1). it can.

As shown in FIG. 3, the front end portion P <b> 1 of the roll towel P is in a state of being drawn out near the outlet 3. Usually, when the roll towel P is cut off by the user, the cut end (tip portion P1) of the roll towel P is located in the vicinity of the outlet 3.
Further, the cutout portion 5 is attached to the lower end portion 12a of the lid body 12 so that the distal end portion 51 is directed in the inner direction of the housing 1 (the arrow direction Y in the drawing) rather than the vertical direction. The cut-out portion 5 is formed by forming a substantially rectangular plate-like member having a maximum thickness of about 5 mm so that the thickness becomes thinner toward the tip portion 51, and the sandpaper 6 is attached to the tip portion 51. (See FIG. 4). That is, the sandpaper 6 is attached to the cutout portion 5 so as to cover the front end portion 51. When the user presses the roll towel P against the tip portion 51 of the cut-out portion 5, the roll towel P is caused by friction with the abrasive applied to the surface of the sandpaper 6 attached so as to cover the tip portion 51. It will be cut out.

  The sandpaper 6 is, for example, a paper-like sheet coated with an abrasive and is generally used for polishing. In the sandpaper 6, the roughness of the eyes is defined by the particle size of the abrasive (the particle size of the abrasive fine powder), and is described as, for example, # 100. As for the particle size of the polishing fine powder, the coarser the number, the smaller the number (for example, # 60), and the finer the particle, the larger the number (for example, # 320). For example, when polishing is performed using sandpaper 6 having a small particle size of the polishing fine powder (coarse), it can be sharpened quickly, but the shaved portion is not smooth. On the other hand, when polishing is performed using the sandpaper 6 having a large particle size (fine mesh) of the polishing fine powder, the shaved portion becomes smooth, but cannot be cut quickly.

  In the roll towel dispenser 100 according to the present embodiment, the sandpaper 6 having a fine particle size of # 100 to # 180 is used. The reason why the sandpaper 6 having a fine particle size of # 100 to # 180 is used is that it is easier for the user to cut the roll towel P than when other sandpaper 6 is used.

  Moreover, in the roll towel dispenser 100 which concerns on this embodiment, the cutting part 5 (for example, thickness R = 1mm) with the thin thickness R of the front-end | tip part 51 is used. Here, as shown in FIG. 5, the thickness R of the front end portion 51 of the cutout portion 5 is the portion of the sandpaper 6 attached so as to cover the front end portion 51 of the cutout portion 5, That is, it is the thickness of the part that directly contacts the pressed roll towel P. The reason why the cutting portion 5 having the thin thickness R of the tip portion 51 is used is that the thinner the thickness R, the easier the user can cut the roll towel P.

  In addition, the paper sheet which concerns on this embodiment is manufactured by using only virgin pulp, waste paper pulp, or a mixture thereof as a paper stock, for example. When used paper pulp is used, 100% used paper pulp or virgin pulp may be blended. Moreover, the kind of pulp fiber is not particularly limited, but it is preferable to use softwood pulp in an amount of 60 to 100% by weight, particularly preferably 80 to 100% by weight, and a remaining amount of hardwood pulp. By making high-blend hardwood pulp with short fibers, the influence of fiber orientation is reduced, and easier and more precise tearing is possible.

The basis weight of the paper sheet can be, for example, about 15 to 65 g / m ² measured according to JIS P 8124 (1998). Among these, a thick one having a basis weight of 30 to 60 g / m ² is preferable. Particularly preferred are those having a basis weight of 30 to 50 g / m ² .

  The paper sheet preferably has an aspect ratio of dry tensile strength defined by JIS P 8113 (1998) of 2.0 or less, particularly preferably 1.0 to 1.8. This aspect ratio can be adjusted by changing various papermaking conditions such as the jet wire ratio in the wire part. By keeping the aspect ratio (longitudinal / lateral) of the dry tensile strength low, the occurrence of longitudinal tearing is reduced and tearing closer to a straight line becomes possible.

  Further, the paper sheet preferably has a tensile elongation at break (longitudinal direction) defined by JIS P 8113 (1998) of 16% or less, and particularly preferably 13% or less. The tensile elongation at break can be adjusted by the degree of creping (so-called crepe rate). By keeping the tensile elongation at break low, it is possible to prevent the direction of the tearing force applied to the paper from changing irregularly due to the elongation of the paper, and to reduce the occurrence of tearing in the longitudinal and oblique directions.

  In a more preferred form, the paper sheet has a transverse tear strength of 65 gf or less as defined in JIS P 8116 (2000). The aspect ratio of the tear strength is preferably 0.75 or more, particularly 0.8 or more. The tear strength in the transverse direction can be adjusted by changing the blending of pulp, the degree of beating (freeness), the tensile elongation at break, and the like. If the transverse tear strength and the aspect ratio of the tear strength are within this range, not only will the force required for tearing be appropriate, but it will be difficult to apply unnecessary force in unnecessary directions, resulting in a more beautiful tear. Will be able to.

  The paper sheet is suitable for a roll-shaped product, particularly a roll-shaped paper towel, which is formed by rolling a paper sheet and tearing it along the lateral direction. In such a product, there is a form in which a plurality of paper sheets are used as one sheet, but in such a form, test values such as dry / wet tensile strength, tensile break elongation, and tear strength are in a single sheet state. Means a value.

Although this invention is not limited to a roll-shaped paper towel, For example, when setting it as a roll-shaped paper towel of about 30-40 g / m < ² > measured according to JISP8124 (1998), as a measuring method of paper thickness. , Measured under the conditions of JIS P 8111 (1998) using a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho), 140 to 220 μm, and wet tensile strength (JIS P 8135) 1998)) is preferably 500 to 1500 cN / 25 mm in the vertical direction and 200 to 100 cN / 25 mm in the horizontal direction, and the water absorption is 100 mm on a test piece placed on a net, and a container containing the whole net and water. The specimen was lifted after sufficient penetration of water into the specimen, and the mass of the specimen was measured after being left for 30 seconds. The mass at the time of drying was subtracted from this measured mass by 100 to obtain the amount of water absorption per 1 m ² . Is preferably from 100 to 200 g / m ^2, dry tensile strength (JIS P 8113 1998) is within a range satisfying the aspect ratio, the vertical direction 1400~3000cN / 25mm, the lateral is 600~1700cN / 25mm Is preferred.

Next, the cutting operation of the roll towel P according to the roll towel dispenser 100 will be described.
When the user performs an operation of pulling out a piece (tip portion P1) of the roll towel P located near the outlet 3, the roll towel P is moved along with the rotation of the roll towel P supported by the paper support unit 4. Pulled out. After the user pulls out the roll towel P to a desired length, the user presses the desired position of the roll towel P against the distal end portion 51 of the cutout portion 5 attached to the lower end portion 12a of the lid body 12 and pulls it upward. Perform the action. At this time, the roll towel P is pressed against the sandpaper 6 attached so as to cover the front end portion 51, and is torn along the width direction by friction with the abrasive applied to the surface of the sandpaper 6, and cut off. Will be.

Here, the cut edge of the roll towel P is compared between the case where it is cut by the cutting blade according to the prior art and the case where it is cut by the cut portion 5 according to the present embodiment.
When cut with a cutting blade according to the prior art, as shown in FIG. 6A, the cut edge of the roll towel P is in a jagged state, giving a rough and cheap impression to the user.
On the other hand, when cut by the cut portion 5 according to the present embodiment, as shown in FIG. 6B, the cut edge of the roll towel P is clean and smooth, and can give a high-grade and soft impression to the user. .

  EXAMPLES Next, although an Example is given and this invention is demonstrated more concretely, of course, this invention is not limited to these Examples.

[Example]
As the roll towel P, the rice weight is 32.5 g / m ² , the dry tensile strength is 2319 cN / 25 mm in length, 1972 CN in width, the wet tensile strength is 1069 cN / 25 mm in length, 704 cN / 25 mm in width, the water absorption is 162 g / m ² , paper The one having a thickness of 183 μm was used.

The resistance force related to the cutting operation of the roll towel P is measured for each particle size of the abrasive fine powder of the sandpaper 6.
[Test method]
First, as shown in FIG. 7, the leading end P1 of the drawn roll towel P is placed on a substantially rectangular plastic plate (dimensions: 50 × 180 mm, thickness: 1 mm) 7 and craft tape (dimensions: 50 × 190 mm) 8 Adhere and fix both sides. As the craft tape 8, “313-50” (Nichiban Co., Ltd.) was used.
Next, a circular hole 71 (a distance T from the bottom of the plastic plate 7 to the center of the circular hole 71 is 20 mm, a distance W from the right side to the center of the circular hole 71 in FIG. The joint 91 of the push-pull gauge 9 capable of measuring the force for pushing and pulling the object is inserted at a position of 30 mm, and the push-pull gauge 9 is attached to the plastic plate 7. The circular hole 71 was installed at a position held by hand when the roll towel P was used. As the push-pull gauge 9, “DPS-20” (Imada Co., Ltd.) was used.
Then, by pulling the push-pull gauge 9 toward the front side (left direction in FIG. 7), the roll towel P is pulled up by pulling up the roll towel P through the plastic plate 7.
Finally, from the display of the push-pull gauge 9, the maximum resistance force measured by the cutting operation is recorded.
As shown in FIG. 8, the angle α formed by the direction from the tip 51 to the other end 52 of the cut portion 5 and the roll towel P pressed against the tip 51 is 20 ° to 120 °. Measurements were made over a range.
[Evaluation method]
It is a sensory evaluation on the ease of cutting off the roll towel P by the user,
◯: Can be cut out smoothly; Δ: Feels a little resistance but easy to cut out; X: Can be cut out but is difficult to cut out XX;
The results are shown in Table 1.
[Test results]
The upper part of Table 1 represents the resistance (unit kgf) related to the cutting operation of the roll towel P under the conditions of the particle size of the abrasive fine powder of the sandpaper 6 and the angle α.

As shown in the lower part of Table 1, it was found that when the grain size of the abrasive fine powder was # 100 to # 180, the user felt ease of cutting.
It was also found that the user felt ease of cutting when the angle α was 45 ° ≦ α ≦ 70 °.

Next, the resistance force related to the cutting operation of the roll towel P is measured for each thickness R of the tip portion 51 of the cutting portion 5.
[Test method]
The test method is the same as the test related to the particle size of the fine abrasive powder.
In addition, the particle size of the abrasive fine powder of the sandpaper 6 was measured under the conditions of # 150 and angle α = 90 °.
The results are shown in Table 2.
[Test results]
In Table 2, the resistance force (unit kgf) related to the cutting operation of the roll towel P for each thickness R of the tip portion 51 of the cutting portion 5 is shown.

As shown in Table 2, when the thickness R of the front-end | tip part 51 of the cut-out part 5 is 1 mm, it turned out that the force concerning a cut-off operation is the smallest (0.20 kgf). On the other hand, when the thickness R of the front-end | tip part 51 of the cutting part 5 is 4 mm, it turned out that the force which concerns on cutting operation is the largest (0.55 kgf).
Therefore, it was found that the thinner the thickness R of the tip 51 of the cut-out part 5 is, the easier the user can cut out the roll towel P.

  As described above, the roll towel dispenser 100 according to the present embodiment is attached with the sandpaper 6 with the grain size of the abrasive fine powder of # 100 to # 180 so as to cover the front end portion 51 of the cutout portion 5. There is no fear of damaging the user's fingers as when using the blade, and the safety of the user can be ensured. In addition, the cut edge of the roll towel P is clean and smooth compared to when a cutting blade is used, and a high-grade and soft impression can be given to the user. Furthermore, compared with the case where a metal cutting blade is used, the cutting portion 5 to which the sandpaper 6 is attached can be made at a low cost and is easy to return naturally, so it is good for the environment. Further, the user can cut the roll towel P with a small force, and can easily cut the roll towel P even by a child or an elderly person.

  Further, in the roll towel dispenser 100 according to the present embodiment, the angle α formed by the cut portion 5 between the direction from the tip portion 51 to the other end 52 and the roll towel P pressed against the tip portion 51 is 45. Since it is attached so that the angle is less than or equal to α ≦ 70 °, the user can cut the roll towel P with a small force, and even the child or the elderly can easily cut the roll towel P.

  As mentioned above, although concretely demonstrated based on embodiment which concerns on this invention, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

For example, in the above-described embodiment, as illustrated in FIG. 3, the cutout portion 5 is attached to the lower end portion 12 a of the lid body 12, but is not limited thereto.
For example, as illustrated in FIG. 9A, the cutout portion 5 may be attached above the lower end portion 12 a of the lid body 12.

  Moreover, as shown in FIG.9 (b), you may make it attach to the lower end part 12a of the cover body 12 not in the root part (other end 52) of the cut-out part 5, but in an intermediate part. Since the other end 52 of the cutout part 5 is exposed to the outside of the lid body 12 by being attached at the middle part of the cutout part 5, the user can easily recognize the position of the cutout part 5 and the roll. It becomes easy to press the towel P.

  Further, as shown in FIG. 9C, the cutout portion 5 may be attached to the lower surface 11 c of the storage body 11. By attaching the cutout portion 5 to the lower surface 11c of the storage body 11, the user can cut the roll towel P by pulling it downward, so that it can be cut easily compared to pulling it upward and cutting it.

  Moreover, in the said embodiment, although the shape of the cutout part 5 is formed so that thickness may become thin as it goes to the front-end | tip part 51, it is not limited to this. For example, one of the long sides (tip portion 51) of the substantially rectangular plate-like member may be rounded so that the tip portion 51 has a curved shape having a predetermined curvature.

  Moreover, in the said embodiment, although the roll towel P wound by roll shape was illustrated and demonstrated as a paper sheet, it is not limited to this. As long as the paper sheet can be pulled out from the take-out port 3, a sheet made of 99 sheets may be folded and stacked.
