Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First Embodiment)
As shown in FIG. 1, the wrapping material container 1 according to the first embodiment has a rectangular box-shaped container body 10. In the container main body 10, a winding material 20 in which a long thin material P is wound in a roll shape is housed and arranged. The thin material P is provided with perforations (not shown) for cutting the thin material P at regular length intervals. The winding material 20 is housed and arranged in the container main body 10 in a posture in which the center line C faces in the horizontal direction. The container body 10 is formed in a substantially rectangular cuboid shape in which the length of one side is slightly longer than the length along the center line C of the winding material 20.

The upper wall 12 of the container body 10 is provided with an opening 30 for pulling out the thin material P derived from the winding material 20 housed in the container body 10 from the container body 10. The opening 30 has a slit portion 32 extending in the horizontal direction along the center line C of the winding material 20. Further, the opening portion 30 has two extending portions 34, 34 extending in a direction away from each other from the center of the slit portion 32 in the longitudinal direction. The extending portion 34 extends in a direction substantially orthogonal to the slit portion 32. That is, the opening 30 is a substantially cross-shaped opening.

The width of each extending portion 34 in the direction orthogonal to the extending direction is wider than the width in the direction orthogonal to the longitudinal direction of the slit portion 32. The slit portion 32 passes the thin material P derived from the winding material 20. The length of the slit portion 32 is slightly shorter than the width of the thin material P. Both ends of the slit portion 32 in the longitudinal direction are curved in an arc shape so that the edge of the thin material P is not easily caught. The two extension portions 34 are generally wide enough to insert the thumb and index finger. The extending end of the extending portion 34 is also curved in an arc shape. The edges of the slit portion 32 and the edges of the two extending portions are also gently connected. As a result, the thin material P drawn out from the container body 10 through the opening 30 is less likely to be caught on the edge of the opening 30.

By making the length of the slit portion 32 shorter than the width of the thin material P, a frictional force acts between the longitudinal end edge of the slit portion 32 and the edge of the thin material P, and the slit portion 32 is pulled out from the opening 30. It is possible to make it difficult for the thin material P to be drawn into the container body 10. That is, it is possible to maintain the state in which the end portion of the thin material P is pulled out of the opening 30 as shown in FIG. If the end of the thin material P is pulled into the container body 10 through the opening 30, two fingers are inserted through the two extending portions 34 to make the thin material P thin. The end portion of the material P can be picked and pulled out of the container body 10.

The opening 30 is provided, for example, by cutting a piece of paper from the upper wall 12 along a perforation (not shown) when the winding material container 1 is used. Therefore, the shape of the piece of paper to be cut is substantially the same as the shape of the opening 30. When removing a piece of paper, a part of the piece of paper is extruded from the inside of the upper wall 12 (inside of the container body 10) to the outside, and a part of the extruded piece of paper is picked and separated from the upper wall 12. The perforations that define the circumference of the piece of paper are formed by pressing a cutter tooth (not shown) from the inner surface side of the upper wall 12 to partially cut the upper wall 12 in a dotted line. Therefore, the edge of the opening 30 after cutting the piece of paper is slightly folded outward as shown in FIG.

The container body 10 is formed by processing one sheet material into a predetermined shape and bending it. In the present embodiment, as the sheet material, a paperboard 40 having a three-layer structure is used as shown in the cross section in FIG. The sheet material is not limited to a three-layer structure, and may have a two-layer structure or a multi-layer structure having four or more layers. In the present embodiment, the first layer 42 (lowermost layer in the drawing), which is the innermost layer facing the inside of the container body 10, is formed of pure pulp, and the third layer 46 (the outermost layer) facing the outside of the container body 10 is formed. The uppermost layer in the figure) was formed of pure pulp having a surface coarser than the surface of the first layer 42, and the intermediate layer 44 was formed of recycled paper pulp or a material obtained by combining recycled paper.

That is, in order to reduce the coefficient of friction between the surface of the first layer 42 constituting the inner surface of the container body 10 and the thin material P of the winding material 20, the material is thinner than the third layer 46, which is the outermost layer of the three layers. The first layer 42 having a small coefficient of friction with P was placed inside the container body 10. In other words, in the present embodiment, the paperboard 40 is bent in the direction in which the first layer 42 is on the inner surface side of the container body 10 to form the container body 10. The friction coefficient referred to here includes both the static friction coefficient and the dynamic friction coefficient between the first layer 42 and the thin material P.

Alternatively, as the paperboard 40, all the layers 42, 44, 46 may be formed of pure pulp, and in this case as well, the coefficient of friction of the innermost layer 42 with respect to the thin material P is smaller than the coefficient of friction with the outermost layer 46. Therefore, the material of the innermost layer 42 may be selected. Alternatively, the innermost layer 42 may be formed of pure pulp, and the second layer 44 and the third layer 46 may be formed of recycled paper pulp. In any case, in order to obtain surface smoothness, it is desirable to use hardwood (short and thin fibers) virgin pulp having a finer surface than softwood for the first layer 42.

The wrapping material 20 is, for example, a roll paper obtained by rolling a long piece of paper carrying a deodorant such as activated carbon or bincho charcoal into a roll shape, and itself functions as a deodorant. Alternatively, the wrapping material 20 may be a roll paper carrying a chemical such as a deodorant or a fragrance. At the time of shipment of the wrapping material container 1, the wrapping material 20 is housed in the container main body 10 in a state of being wrapped in, for example, a plastic bag, and the user once takes out the wrapping material 20 from the container main body 10 and breaks the wrapping material 20. Return only to the inside of the container body 10. At this time, the winding material 20 is put into the container body 10 in a posture in which the center line C of the winding material 20 is parallel to the slit portion 32, and the end portion of the thin material P of the winding material 20 is inserted from the slit portion 32 of the opening 30. Pull it out a little.

Hereinafter, the effects of the first embodiment described above will be described with reference to FIGS. 1 and 2.
As shown in FIG. 2, when the thin material P of the winding material 20 is pulled out from the opening 30 of the container body 10 in the direction of the arrow in the drawing, the thin material P slides on the edge of the opening 30 and a frictional force is generated between the two. It works. As shown in FIG. 1, the slit portion 32 is provided along the center line C of the winding material 20. Therefore, the thin material P drawn out through the slit portion 32 is in sliding contact with the edge of the slit portion 32 on the side where the thin material P is drawn out from the winding material 20. At this time, as shown in FIG. 2, the thin material P comes into contact with the edge of the slit portion 32 diagonally. That is, the thin material P is pulled out from the opening 30 while being in contact with the first layer 42 inside the paperboard 40 of the upper wall 12.

At this time, if the frictional force acting between the edge of the opening 30 (the edge of the first layer 42) and the thin material P is large, the pulling force required to pull out the thin material P from the opening 30 is large. Become. Then, the thin material P may be caught by the edge of the opening 30 and torn while the thin material P is being pulled out. When the thin material P has perforations for cutting at predetermined lengths as in the present embodiment, it is desirable to prevent the thin material P from being torn at a portion other than the perforations.

Therefore, in the present embodiment, in order to prevent the thin material P from being torn at an undesired portion when the thin material P is pulled out from the opening 30, various measures are made to prevent the thin material P from being caught on the edge of the opening 30. Was applied to the roll material container 1. First, the edge of the opening 30 is formed into a gently curved curved shape so that the thin material P is less likely to be caught on the edge of the opening 30.

Secondly, when forming a perforation on the paperboard 40 for cutting a piece of paper in the shape of the opening 30 so that the edge of the opening 30 is slightly folded outward (upper in the drawing) as shown in FIG. Cutter teeth were pressed against the upper wall 12 of the paperboard 40 from the inside of the wrapping material container 1 to form perforations. Further, as a method of using the wrapping material container 1, it is described in the container body 10 that a part of the paper piece is pushed outward from the inside of the upper wall 12 and the paper piece is removed from the front side of the upper wall 12.

Third, the upper wall 12 (that is, the paperboard 40) forming the opening 30 has a multi-layer structure, and the coefficient of friction between the first layer 42, which is the innermost layer including the inner surface of the container body 10, and the thin material P is set. It was made smaller than the coefficient of friction with the outermost layer 46. In other words, the paperboard 40 was bent in the direction in which the first layer 42 having a relatively small coefficient of friction was arranged on the inner surface side of the container body 10 to form the wrapping material container 1.

The container body 10 having the first to third configurations described above is simply formed by shaping one sheet of paper 40 as in the present embodiment and bending the first layer 42 inward. Can be formed. That is, the wrapping material container 1 of the present embodiment does not require a configuration other than the paperboard 40. Therefore, it is easy to manufacture, and the manufacturing cost can be reduced accordingly.

As described above, according to the present embodiment, since the first to third configurations described above are provided in the container main body 10, when the thin material P of the winding material 20 is pulled out through the opening 30 of the upper wall 12, the thin material P of the winding material 20 is pulled out. The frictional force between the thin material P and the edge of the opening 30 can be reduced. Therefore, according to the present embodiment, it is possible to suppress a defect that the thin material P is torn at an undesired position when it is pulled out from the opening 30.

It should be noted that such an effect of the present embodiment can be obtained even if all of the above-mentioned first to third configurations are not provided. For example, even if only the third configuration is provided, the effect of the present embodiment can be obtained. Can play.

(Second embodiment)
FIG. 3 is a cross-sectional view showing a main part of the winding material container 1 according to the second embodiment, and is a view corresponding to FIG. 2. The wrapping material container 1 of the second embodiment has substantially the same structure as the wrapping material container 1 of the first embodiment described above, except that the structure of the paperboard 50 for forming the container body 10 is different. Therefore, here, the components having the same function as the winding material container 1 of the first embodiment described above are designated by the same reference numerals, and detailed description thereof will be omitted.

The paperboard 50 of the wrapping material container 1 of the present embodiment has a structure in which one surface 52a (inner surface when the container body 10 is formed) of the sheet material 52 as a base material is coated with a coating material 54 (coating layer). .. The sheet material 52 may be pure pulp, recycled paper pulp, recycled paper, or a single-layer or multi-layered paperboard obtained by combining these materials, and may be, for example, the paperboard 40 of the first embodiment. good. Alternatively, the paperboard 50 may be a sheet material 52 formed of a material other than pulp-free paper and coated with a coating material 54. For example, the sheet material 52 may be formed of a material in which resin and paper are mixed.

The coating material 54 is for coating the surface of a printed matter, for example, to improve glossiness, waterproofness, abrasion resistance, and the like. When the coating material 54 is coated on the surface of the sheet material 52, the coefficient of friction between the coating material 54 and the thin material P is smaller than the friction coefficient between the surface 52a of the sheet material 52 and the thin material P. Any material may be used as long as it can form a smoother surface than the surface 52a of the sheet material 52.

Examples of the sheet material 52 described above include, for example, coated card paper, coated cardboard, and coated ivory paper. In coated card paper, for example, one surface of a base material in which the first layer and the third layer are formed of pure pulp and the intermediate layer (second layer) is formed of upper white waste paper or newspaper waste paper is surface-treated. It is a paperboard. The coated cardboard is, for example, a paperboard in which the first layer is formed of pure pulp and the second and third layers are formed of recycled pulp and the surface of the base material on the first layer side is surface-processed. The coated ivory paper is a paperboard in which all three layers are surface-treated on one surface of a base material formed of pure pulp.

The surface processing referred to here includes, for example, a processing in which a white pigment (clay such as clay or kaolin or calcium carbonate) is applied to the surface of paper with a glue such as starch. By such surface treatment, the smoothness, glossiness, and whiteness of the paper surface can be improved, the printing quality can be improved, and the coloring effect can be improved. That is, this surface treatment corresponds to the surface treatment of the base material before coating the coating material 54.

On the other hand, the coating material 54 is a material for improving the glossiness, waterproofness, abrasion resistance, etc. of the surface of the sheet material 52. Therefore, a coating with a coating material 54 may be applied on the above surface treatment. That is, the surface coating (surface processing) previously applied to the surface of the paperboard such as coated card paper, coated cardboard, and coated ivory paper is not included in the coating material 54 referred to here.

The coating material 54 includes a varnish type, a press type, a laminate type, a vinyl type and the like. The varnish-based coating material can be applied by applying a transparent varnish liquid to the surface of a base material such as the sheet material 52 and drying it. As processing with a varnish-based coating material, for example, there are gloss varnish, matte varnish, acrylic coat, acrylic matte coat and the like.

The press-based coating material can be applied by applying a brightener to the surface of the base material and then transferring a metal plate or a film. Processing with a press-based coating material includes, for example, a press coat, a UV clear coat, an SP emboss coat, and an acrylic press coat.

The laminated coating material can be processed by laminating a film on the surface of the base material. As processing with a laminated coating material, for example, there are laminating processing, mat laminating and the like.

The vinyl-based coating material can be applied by applying a liquid obtained by mixing a vinyl chloride-based synthetic resin and a quick-drying varnish to the surface of the base material and drying it by heat.

When the container body 10 of the present embodiment is formed by using the above-mentioned paperboard 50, it is necessary to bend the paperboard 50 so that the surface coated with the coating material 54 becomes the inner surface of the container body 10. When forming a box of goods using the above-mentioned cord card paper, coated cardboard, coated ivory paper, etc., the paperboard is usually folded so that the coating material 54 faces the outer surface of the box. That is, the coating material 54 is usually provided to coat the printed surface, which is the surface of the box, to improve glossiness, waterproofness, abrasion resistance, and the like.

On the other hand, the present embodiment is characterized in that the paperboard 50 such as cord card paper, coated cardboard, and coated ivory paper is used so that the coating material 54 faces inward. That is, according to the present embodiment, the wrapping material container 1 is manufactured by using generally known code card paper, coated cardboard, coated ivory paper, and the like upside down. Therefore, as in the first embodiment described above, the winding material container 1 can be formed only by shaping and bending one sheet of paper 50, and no other constituent elements are required. It can be easily done and the manufacturing cost can be reduced.

Further, according to the present embodiment, as shown in FIG. 3, when the thin material P is pulled out from the opening 30, the thin material P is in sliding contact with the coating material 54 of the paperboard 50 of the upper wall 12, so that the first described above is made. The same effect as that of the embodiment can be obtained. That is, when the thin material P is pulled out, the frictional force between the thin material P and the edge of the opening 30 can be reduced, and the problem that the thin material P is torn at an undesired position can be suppressed.

(Test to verify the effect)
The inventors of the present application conducted the tests described below in order to verify the effects of the first and second embodiments described above.
First, the paperboards 40 and 50 of each of the above-described embodiments were used to form a roll material container 1 having the same structure, respectively. A wrapping material 20 of the same type and the same weight (amount) was housed in the container body 10 of the wrapping material container 1, and the thin material P was pulled out from the opening 30. Then, a test was conducted in which the thin material P was pulled out 60 cm upward from the opening 30 at a speed of 2000 mm / min using a tensile tester (not shown). At this time, three tests were performed on each sample, and the average value (N) of the torque (tensile load) for pulling the thin material P, the maximum value (N) of the tensile load, and the thin material P were in the middle of the test. It was measured whether or not it was cut off. If the thin material P ran out, the test was terminated at that point. The results are shown in FIG.

As a sample of the paperboard 40, a coated card paper (Example 1) not coated with the coating material 54 is prepared, and the first layer 42 having a small friction coefficient is arranged on the inner surface side of the container body 10 of the paperboard 40. It was bent into a roll material container 1 to form a roll material container 1. Further, as a sample of the paperboard 50, a coated cardboard (Example 2) in which the inner surface side of the container main body 10 was coated with the coating material 54 was prepared, and the wrapping material container 1 was formed using the paperboard 50. Further, the front and back sides of the coated cardboard of Example 2 were inverted to form a wrapping material container 1 (Comparative Example 1) having the coating material 54 on the outer surface side of the container main body 10.

That is, in the first embodiment, the paperboard 40 is bent in the direction in which the first layer 42 having a relatively small friction coefficient is arranged on the inner surface side to form the container body 10, and in the second embodiment, the coating material 54 faces the inner surface. The paperboard 50 was bent in the direction to form the container body 10. Further, in Comparative Example 1, the container body 10 was formed by bending the paperboard 50 in the direction in which the coating material 54 faces the outer surface, as in the conventional product.

As shown in FIG. 4, when Example 1 and Comparative Example 1 are compared, it can be seen that the average value of the tensile load and the maximum value of the tensile load are both smaller in Example 1 than in Comparative Example 1. That is, from this result, it can be seen that the frictional force between the edge of the opening 30 and the thin material P is smaller in the winding material container 1 of the first embodiment than in the comparative example 1. Further, in Comparative Example 1, the thin material P was cut off in the middle in all three tests, but in Example 1, the test could be continued to the end without breaking in the middle.

Further, looking at the test results of Example 2, it can be seen that both the average value and the maximum value of the tensile load of Example 2 are smaller than those of Example 1. From this, it can be seen that the frictional force between the edge of the opening 30 and the thin material P is further smaller in the second embodiment than in the first embodiment. Further, in the examples as well, the thin material P did not break in the middle of the test, and the test could be carried out to the end.

From the above results, both of the wound material containers 1 of the first and second embodiments described above reduce the frictional force acting between the thin material P and the edge of the opening 30 as compared with the conventional product. You can see that it is done. Therefore, according to the winding material container 1 of the first and second embodiments, it is possible to make the thin material P difficult to tear when the thin material P is pulled out from the opening 30.

(Evaluation of ease of withdrawal)
For the above-mentioned three samples (Example 1, Example 2, Comparative Example 1), five evaluators evaluated the ease of drawing out the thin material P. At this time, the evaluator held each sample of the wrapping material container 1 placed on the desk with his left hand in a standing posture, and pulled out the thin material P from the opening 30 by about 60 cm with his right hand. Then, based on the evaluation criteria shown in FIG. 5, five evaluators gave each sample a score of five grades and examined the average score of the five. At this time, as shown in FIG. 6, when the average score is 1.0 to 2.0, it is ×, when it is 2.1 to 3.0, it is Δ, and when it is 3.1 to 4.0, it is ○, 4. The cases of 1 to 5.0 were evaluated as ⊚. The results are shown in FIG.

Looking at the results of FIG. 7, the evaluation of the sample of Comparative Example 1 was Δ, the evaluation of the sample of Example 1 was ◯, and the evaluation of the sample of Example 2 was ⊚. From this result, compared with the conventional product (Comparative Example 1), the wrapping material container 1 of the first and second embodiments was highly evaluated in terms of the ease of pulling out the thin material P. I understood.

(Third embodiment)
FIG. 8 is a cross-sectional view showing a main part of the winding material container 1 according to the third embodiment, and is a view corresponding to FIGS. 2 and 3. The wrapping material container 1 of the third embodiment has substantially the same structure as the wrapping material container 1 of the first and second embodiments described above, except that the structure of the paperboard for forming the container body 10 is different. Therefore, here, the components having the same functions as the winding material container 1 of the first and second embodiments described above are designated by the same reference numerals, and detailed description thereof will be omitted.

The paperboard of the roll material container 1 of the present embodiment is formed of a single-layer sheet material 60. The sheet material 60 may be pure pulp, recycled paper pulp, used paper, or a single-layered paperboard obtained by combining these materials. Alternatively, the sheet material 60 may be formed of a material other than paper that does not contain pulp, or may be formed of a material that is a mixture of resin and paper. As a material other than paper that does not contain pulp, the sheet material 60 may be formed of a resin or a non-woven fabric.

For example, when the sheet material 60 is formed from pure pulp, the raw material for paper is thinly spread on a wire mesh and dehydrated. The raw material is then passed between the roll and felt for further dehydration. Then, the dehydrated sheet-shaped raw material is dried and wound up. When the raw material is spread in a sheet shape on the wire mesh and dehydrated, fine fillers / chemicals and fine fibers fall off with water on the back side of the raw material sheet facing the wire mesh, leaving long large fibers and the like. Therefore, the back surface 60b of the completed sheet material 60 has a rough surface as compared with the surface surface 60a (the surface not facing the wire mesh).

Therefore, the sheet material 60 formed as described above has two sides having different smoothness between the front surface and the back surface. That is, the front surface 60a of the sheet material 60 becomes a smooth surface having higher smoothness than the back surface 60b. In the present embodiment, utilizing the duality of the paper, the sheet material 60 is bent so that the relatively smooth and smooth surface 60a is arranged on the inner surface of the wrapping material container 1 to form the container body 10. did.

As described above, according to the third embodiment, when the thin material P is pulled out from the opening 30, the thin material P is in sliding contact with the surface 60a of the sheet material 60, so that the first and second embodiments described above are made. Can produce the same effect as. That is, when the thin material P is pulled out, the frictional force between the thin material P and the edge of the opening 30 can be reduced, and the problem that the thin material P is torn at an undesired position can be suppressed.

Further, according to the third embodiment, it is not necessary to coat the surface 60a of the sheet material 60 with a coating material, and as in the first and second embodiments described above, one sheet of paper is shaped and bent. Since the wrapping material container 1 can be formed only by itself and does not require other components, the wrapping material container 1 can be easily manufactured and the manufacturing cost can be further reduced.

Although the present invention has been described above based on some embodiments, the present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the gist of the present invention. Of course.

For example, in the above-described embodiment, the case where the shape of the opening 30 formed in the upper wall 12 of the container body 10 is formed into a cross shape having a slit portion 32 and two extending portions 34 has been described. The shape of the opening 30 is not limited to any shape, such as an oval shape, an elliptical shape, a polygonal shape, and a star shape.

Further, in the paperboard 40 according to the first embodiment described above, the coefficient of friction between the innermost layer (first layer 42) arranged on the inner surface side of the container body 10 and the thin material P is at least the outermost layer (third). The material of the intermediate layer (second layer 44) may be arbitrarily changed as long as it is smaller than the coefficient of friction between the layer 46) and the thin material P.
