[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The embossing ruled line provided on the blower of the flexible paper fan of the present invention includes straight lines, curved lines, etc., and also includes combinations thereof (FIGS. 6, 9, and 11). . In addition, there is another type in which an embossing rule line is provided in a radial direction from the lower center of the blower (FIGS. 1, 4, and 10). The provision of the embossed ruled line in the radial direction means that the embossed ruled line is not only a straight line, but also a curve (FIG. 7) or an elliptical embossed ruled line (FIG. 5). ). Further, the grip portion may or may not be provided.
In the case where the embossed ruled lines are provided in a radial pattern, the number of embossed ruled lines is preferably 5 to 10 in consideration of the strength and the scene of designing an advertisement. Further, in a structure in which a double-sided cardboard having a three-layer structure sandwiches and grasps the gripping portion and the lower central finger catching portion in a substantially mushroom shape, the step of the core of the cardboard has an angle with respect to the gripping portion. Furthermore, the direction of each of the core steps of the one surface to be sandwiched and the other surface is symmetrical with respect to the grip portion.

Hereinafter, the angle between the middle step of the substantially mushroom-shaped double-faced corrugated cardboard for holding the gripping portion and the center finger catching portion of the lower portion of the blower and the gripping portion will be described in detail. When a substantially mushroom-shaped double-faced corrugated cardboard is manufactured as shown in FIG. 3 (b) and is sandwiched between a gripping portion and a center finger catching portion at a lower portion of the blower, one surface and the other surface of the corrugated cardboard corrugated core are corrugated. Both are parallel to the gripping direction, that is, 0 degrees. Although a certain level of strength can be secured from the sandwiched structure, considering that the corrugated cardboard is a structure that is weak against the force in the direction along the corrugation, the corrugated core corrugations on one surface and the other surface also In the parallel state, the drag range is narrow. Furthermore, since the cut surface (11) shown in FIG. 3B becomes sharp, the hand is easily damaged when grasped, which is not preferable. Next, as shown in FIG. 3C, when a substantially mushroom-shaped double-faced corrugated cardboard is manufactured and sandwiched between the gripping portion and the lower central finger catch portion of the blower, one side and the other side of the corrugated cardboard are interposed. The level of the core is 90 with respect to the gripping direction.
It becomes degree. In terms of strength, as in the case of 0 degrees,
The core corrugations of the corrugated cardboard on one surface and the other surface are still parallel to each other, and the drag range remains narrow. Further, although the sharpness of the cut surface in this case is reduced as compared with the case of the above-mentioned 0 degree, it is not optimal because the ratio of the cut surface occupied by the cardboard base paper is smaller than in the following case. Next, it is assumed that a substantially mushroom-shaped double-faced cardboard is manufactured as shown in FIG. In this case, as shown in the upper part of FIG. 1, the substantially mushroom-shaped double-faced corrugated cardboard, the corrugated cardboard corrugations on one surface and one surface have angles in different symmetric directions with respect to the gripping portion. Become. The one-dot chain line in the instep of FIG. 1 indicates one side, and the two-dot chain line indicates the center step of a double-sided cardboard on the other side. By having such a structure,
The range of drag is widened, which is preferable in terms of strength. Further, the cut surface (11) shown in FIG. 3A has a larger proportion of the cut surface of the cardboard base paper than the cut surface (11) shown in FIGS. 3B and 3C. That is, only the cut surfaces of both liners do not hit the finger, so that sharpness can be further eliminated.

Preferably, as long as the corrugated cardboard stitches on one surface and one surface are not parallel to each other as in the case of 0 ° and 90 ° but have an angle with each other, the bending direction The range of drag against is widened. Further, it is more preferable to manufacture the corrugated cardboard on one side and the other side so that the corrugated step of the corrugated cardboard has an angle in different symmetrical directions with respect to the gripping part, since an almost mushroom-shaped corrugated cardboard can be integrally formed. And the angle between the double-sided corrugated cardboard core and the gripping part direction is
Considering the sharpness of the cut surface, it is desirable to provide an angle of 10 degrees or more. As the angle approaches 45 degrees and approaches 90 degrees, the area of the cut surface becomes smaller, becomes sharp at the same time, and is generated by fanning. In the present invention, it is considered that the case where the step of the core of the corrugated cardboard has an angle of 10 degrees to 45 degrees with respect to the gripping portion is considered to be optimal because the resistance to the bending direction is also reduced.

This double-faced cardboard is shown in FIG.
It may be manufactured by punching from one leaf, or may be made separately by changing the angle of the center step with respect to the gripping part on one side and one side. The double-faced cardboard has a step height of 1.1 to 1.6 mm and a number of peaks per 30 cm of 93.
A double-sided corrugated cardboard structure having E steps of ± 5 is preferable, but a corrugated cardboard structure having another numerical value or interleaving paper may be used as long as the effects of the present invention can be maintained and improved. Further, in the flexible paper fan of the present invention which has only a blower having no pattern and having a radially impressed ruled line, a part of the blower is deformed so as to be grippable, or a finger is formed on a part of the blower. A hole may be provided. As the raw material, in addition to virgin pulp, for example, a liquid beverage container made of paper such as a milk pack, a sake pack, a juice beverage, etc., which is processed into recycled paper can be considered. Further, the shape of the reinforcing material in the case of providing the gripping portion and the lower finger catching portion of the blower is not limited to a substantially mushroom shape, but considering the load of the lower finger catching portion of the blower serving as a swing starting point, the load is reduced. It is desired to have a shape that has a sufficient supplementing effect and can be maintained. If a new load is generated at the lower central finger hook portion of the blower due to the shape of the blower, the shape may be supplemented.

[Embodiment 1] A flexible paper fan of the present invention will be described with reference to FIGS. 1, 2, 3 (a) to 3 (c) and FIG. FIG. 1 is a partial perspective view of a finished product of a stiffened paper fan of the present invention, FIG. 2 is a diagram showing a stiffened paper fan body of the present invention before reinforcing a grip portion, and FIG. Exploded view of a three-layer double-sided corrugated cardboard reinforcing piece for reinforcing the gripping part, in which the direction of the core step has an angle of 45 degrees with respect to the gripping part, FIG.
(B) is a three-layered double-faced corrugated cardboard reinforcing piece for reinforcing the gripping portion of the main body, in which the reinforcing piece whose center step is parallel to the gripping portion is shown. FIG. 3 (c) reinforces the gripping portion of the main body. FIG. 8 is a development view of a three-layered double-sided corrugated cardboard reinforcing piece having a 90 ° angle with respect to a gripping portion in the direction of a core step, and FIG. is there.

In the drawing, (1) is a finished product of a flexible paper fan,
(2) a fan body before reinforcing the grip portion, (3) a blower,
(4) embossing ruled line, (5) gripping part, (6) three-layer double-sided corrugated cardboard reinforcing piece, (7) central step of three-layer double-sided corrugated cardboard reinforcing piece, (8) folding fold line, (11) is a cut surface,
(A) is the grip portion after reinforcement, and (P) is the force applied to the blower.

The flexible paper fan of the present embodiment is made of a recycled paper made from a paper liquid beverage container such as a milk pack or a sake pack as the raw material, and the fan body (2) and the three-layer double-faced corrugated cardboard reinforcing piece before the gripping portion is reinforced. It is used for (6).

In the present embodiment, the fan body (2) before reinforcing the grip is punched from recycled paper made from a paper liquid beverage container into the shape of the fan body (2) before reinforcing the grip. However, at the same time as this processing, radially embossed ruled lines (4) are formed in the blower at equal intervals and symmetrically by the ruled line embossing. Similarly, the three-layer double-faced corrugated cardboard reinforcing piece (6) is similarly punched from a three-layer double-faced corrugated cardboard structure using a liquid beverage container made of paper as a raw material in the shape of FIG. 8) is subjected to ruled line embossing. At this time, the corrugation of the cardboard is shown in FIG.
As shown in the middle (7), the reinforcing piece (6) is punched so as to have an angle of 45 degrees with respect to the longitudinal direction.
As described in 0012, the angle is preferably between 10 degrees and 45 degrees.
In addition, the three-layer double-sided corrugated cardboard structure manufactured from recycled paper made from a paper liquid beverage container is a double-sided corrugated cardboard with E steps, the height of the step is 1.1 to 1.6 mm, and the number of peaks per 30 cm. Is 93 ± 5. The finished flexible paper fan of the present invention (1) is obtained by folding a three-layer double-sided corrugated cardboard reinforcing piece (6) at a folding line (8) for folding and holding the gripping portion of the fan body (2) before reinforcing the gripping portion. It is formed by bonding.

The radially-embossed ruled line (4) has an effect of withstanding the flexure generated during use, and this effect will be described with reference to a partially enlarged structural explanatory diagram (FIG. 8) of the blower. Explaining, each embossing ruled line has a dome-shaped cross section, and the shape of the dome absorbs and disperses the force P in the direction of the arrow in FIG. It shows. Further, since the embossing ruled lines (4) are provided not in parallel to each other but in a radial direction, they have excellent bending resistance even when bent obliquely.

Further, a three-layer double-faced corrugated cardboard reinforcing piece (6)
When the body is gripped by folding back at the folding line (8) for folding back, as shown by the dashed-dotted line and the two-dotted dashed line in FIG.
This is because the corrugated cardboard is weak in the force applied in parallel to the direction of the core core and strong in the force applied in the vertical direction. Even when the gripping part and the blower lower central finger hooking part are subjected to loads from various directions including torsion, etc., compared with the case where both steps on both sides to be clamped are clamped in the same direction, the bending resistance is higher. In addition, it has excellent durability and can overcome the weakness of the paper fan in terms of strength. Then, by punching out such that the middle step (7) of the three-layer double-sided corrugated cardboard reinforcing piece (6) has an angle of 45 degrees with respect to the longitudinal direction,
The cut surface (11) does not become sharp and does not hurt the hand. When cut in parallel with the core step, the liner covering the core step appears alone on the cut surface (11), and thus the hand is easily damaged. Further, in comparison with the case where the cutting is performed perpendicularly to the middle core step, the hand according to the present embodiment is less likely to hurt the hand because the cutting area of the middle core is larger. Further, in this embodiment, the effect is further enhanced by using a wave blade as a cutting blade for the punching process and forming a fine corrugated shape (not shown) on the cut surface (11).

Further, in the flexible paper fan of the present invention, since both the blower and the three-layer double-faced corrugated cardboard reinforcing piece are paper or recycled paper, it is not necessary to attach a film for reinforcement to the surface. At the time of disposal, it can be recovered as a recycled product as it is. In particular, when both bodies are made of recycled paper from a milk pack, they can be placed directly on the milk pack recycled paper route. Therefore, for example, the use of the flexible paper fan of the present invention as one of the advertising media by a company informs the public of the company's attitude toward the environment and leads to an increase in the reputation of the company.

[Embodiment 2] As a second embodiment of the present invention, of the flexible paper fan according to the second aspect of the present invention, a fan without a grip portion will be described with reference to FIGS. I do.

FIG. 6 is a front view of a paper fan, and FIG. 6 is a front view of a stiffness-resistant paper fan having embossed ruled lines formed in the form of veins on a blower. FIG. FIG. 4 is a development view in which a bonding portion of a flexible paper fan having a gripping portion at a lower part of the body is partially opened.

In the figure, (9) is a finger hole, (10) is a reinforcing portion, and (1) to (8) are the same as the correspondence between symbols and phrases in the first embodiment.

As in the first embodiment, the blower for the flexible paper fan of the present embodiment is formed from recycled paper made from paper liquid beverage containers such as milk packs and sake packs into the shapes shown in FIGS. The punching process is performed, and at the same time, the embossing ruled line (4) and the folded fold line (8) shown in these figures are formed in the blower by the ruled line embossing process.

In the flexible paper fan shown in FIG. 4, a portion surrounded by a dotted line is used as a grip portion (5), but it is not particularly necessary to provide such a grip portion. Also, when the elliptical embossed ruled lines are arranged in a radial direction as shown in FIG. 5, the bending resistance of the blower is not changed. Can be used as a gripper, and it is also convenient for carrying. In addition, there is an advantage that the design can be made freely because there is no handle as a grip portion, and more various designs are possible when used for advertising of a company or the like. And FIG.
The vein-shaped embossed ruled line shown in (1) does not change the flexing resistance as compared with the radially provided embossed ruled line, and opens up new possibilities in terms of design.

In the flexible paper fan shown in FIG. 7, the blower is provided with a ruled line in which a straight line and a curved line are combined. Even in such a case, the bending resistance of the blower does not change. In addition, the reinforcing portion (10) is folded back toward the blower at the folding line (8), and is bonded to the lower portion of the blower and the grip portion (5), and the reinforcing portion (10) is formed from the width of the grip portion (5). Since the width of (10) is wide (a <b), the lower part of the blower, which is the swing starting point, is reinforced.

Embodiment 3 As a third embodiment of the present invention, a variation of the flexible paper fan of the present invention according to claim 1 will be described with reference to FIGS. FIG.
Is a front view of a stiffness-resistant paper fan provided with an embossed ruled line combining a circle and a straight line on a blower, and FIG. 10 is a stiffness-resistant paper fan obtained by deforming a three-layer double-faced cardboard in accordance with the outer periphery of the blower. FIG. 11 shows a flexible paper fan in which an elliptical ruled line and a linear ruled line are combined in accordance with the outer shape of a blower.

The symbols in the figure are the same as the corresponding symbols and phrases in the first embodiment.

As in the first embodiment, the blower of the flexible paper fan of this embodiment is formed from recycled paper made from paper liquid beverage containers such as milk packs and sake packs into the shapes shown in FIGS. The stamping process is performed, and the embossing ruled line (4) shown in these figures is formed in the blower by the ruled line embossing process performed at the same time.

The flexible paper fan shown in FIG. 9 is provided with embossed ruled lines in which a circle and a straight line are combined to ensure the rigidity. Further, FIG. 10 shows that the three-layer double-faced corrugated cardboard reinforcing piece (6) is adjusted in accordance with the outer peripheral shape in consideration of a load newly applied to the three-layer double-faced corrugated cardboard reinforcing piece (6) by adding the ear portion (12) to the blower. 6) is deformed and the reinforcing one ear part (1
3) is added. Further, by extending the embossing ruled line up to the ear part (12), the bending resistance of the ear part (12) is maintained. In the case where a new load is generated in the lower finger-holding portion of the lower portion of the blower due to the shape of the blower as described above, the shape may be supplemented. FIG. 11 shows a variation of the present invention by providing a straight embossed ruled line on the main body of the blower (3) and an elliptical embossed ruled line on the ear (12). By doing so, the possibility expands in terms of design while maintaining the bending resistance.

[0030]

According to the present invention, since the ruled line embossing process for providing the embossed ruled line can be performed simultaneously with the punching of the blower, there is an advantage in the process. In addition, there is no need for a skeleton such as plastic, and there is an effect of resisting the bending generated during use without attaching a film or the like for reinforcement. Furthermore, the three-layer double-sided corrugated cardboard reinforcing piece of the gripping part, taking into account the direction of the step of the core, is flexible and durable against the load applied to the swing starting point and the gripping part at the center of the lower part of the blower even when violently fanning. It shows an excellent effect. By having the above-mentioned structure, the stiffness-resistant paper fan of the present invention has overcome the strength weakness of the conventional paper fan by using only paper. Furthermore, the use of recycled paper made of paper-made liquid beverage containers has the advantage of strength, such as increased stiffness, and has the effect of effective use of resources. High contribution to In particular, in the case where the milk pack recycled paper is used for both the blower and the three-layer double-faced corrugated cardboard reinforcing piece, it is preferable because the used fan can be left as it is on the route for recycling the milk pack or the like.
