Hereinafter, the present invention will be described in more detail with reference to the drawings.

[Winding tube body]
As shown in FIGS. 1 and 2, the wound tube packaging container body 22 includes a front plate 1 whose shape is rectangular, and a bottom plate 2 whose shape is connected to the long side of the front plate 1 and is rectangular. The rear plate 3 which is connected to the long side of the bottom plate 2 and is opposed to the front plate 1 and has a rectangular shape, and the side plate 8 which is connected to the left and right short sides of the bottom plate 2 is square or rectangular. And the first auxiliary side plate 7 connected at the left and right short sides of the front plate 1 and the second auxiliary side plate 9 connected at the left and right short sides of the rear plate 3. The upper part facing the bottom plate 2 is opened in the wound tube packaging container main body 22, and the wound tubular body 26 inside the wound tube packaging container main body 22 is operated with fingers in the opened state. Yes.

  Specifically, the size (the size of the side plate 8) of the wound tube packaging container body 22 in a side view depends on the inner dimensions of the wound tube package container 22 and accommodates the wound tube body 26. In order to allow the contents to be pulled out, it is at least necessary to configure the size such that there is a gap on the inside when the winding cylinder 26 is accommodated. The size of the winding tube body 26 also depends on the size of the core body 26a and the amount of contents, and the length in the left-right direction (length in the longitudinal direction) of the winding tube body 22 is the winding tube. The length of the shaft of the body 26, that is, the length of the shaft of the core body 26a is slightly longer (so that it can be accommodated) (see FIG. 1A). If the winding tube body 22 is too long with respect to the length of the axis of the core body 26a, when the winding tube body 26 is accommodated, the gap between the left and right ends is too wide, and the winding tube body 21 protrudes. Since the prevention means 45 does not reach the hollow portions at both ends of the core body 26a, the winding cylinder body 26 cannot be fixed.

  Specifically, in relation to the general outer diameter of the wound cylindrical body 26 to be packaged, the inner dimension of one side of the side plate 8 of the wound cylindrical package container body 22 is a square of 30 to 50 mm. The container 21 preferably has a rectangular parallelepiped shape. In particular, considering the ease of use of the winding tube packaging container 21 and the outer shape of the winding tube body 26 to be packaged, the outer dimension of the side plate 8 of the winding tube packing body 22 is a square having a side of around 40 mm, The cylindrical packaging container body 22 is more preferably a rectangular parallelepiped.

  Such a wound tube packaging container 21 can be formed of a thin plate-like material, and is cut into a plan view shape shown in FIG. 2 such as the front plate 1 and the bottom plate 2, the bottom plate 2 and the rear plate 3 and the like. Each of the connected sides is bent at approximately 90 degrees to form a rectangular parallelepiped shown in FIG.

  In particular, the side surface of the wound packaging body 22 is positioned on the innermost surface with the second auxiliary side plate 9 folded, and then the first auxiliary side plate 7 is folded and positioned on the inner surface, and the side plate 8 is the last. The respective plates are formed by bonding or the like in a state of being folded into the outermost surface and positioned on the outermost surface. However, the configuration of the side surface is not limited to the order of folding.

  The material used for the winding tube packaging container 21 is not particularly limited, such as various corrugated cardboards and paper boards. However, in consideration of the recent increase in environmental protection, the packaging tube container 21 after use of the contents is used. It is preferably made of paper such as paper board that can be easily discarded and recycled.

[Attached part of the winding tube packaging container body]
(Folded piece)
As shown in FIGS. 1 to 3, the lid body 23 is fixed to the winding body packaging container body 22 so that the winding body packaging container 21 can be securely closed, and the winding body 26 is taken out as necessary. In order to provide the engagement protrusion 13 for facilitating, the wound tube packaging container 21 has folding pieces 12 formed in a rectangular shape or a square shape at both left and right ends.
In addition, the folded piece 12 can serve as a fall prevention means when the user opens the lid 23 and operates the core body 26a wound with the contents.

  The folding piece 12 is connected to the side plate 8 that forms the outer surface of the wound tubular packaging container body 22 in a predetermined size from the viewpoint of the relationship with the position where the engagement protrusion 13 is provided and the strength of the folding piece 12. . The folding piece 12 includes an engagement protrusion 13 formed by a cut line 19 formed so as to include a part on the side plate 8 side beyond the upper side 18 thereof. Here, the engagement protrusion 13 is formed in a trapezoidal shape.

  The folded piece 12 is folded at approximately 90 degrees from the outer surface side of each side plate 8 to the inner side of the wound tube packaging container body 22 with the upper side 18 of each of the left and right side plates 8 as a folding line 37 and faces the bottom plate 2. By folding the folded piece 12 so as to face the bottom plate 2 at the position of the upper side 18, the engagement protrusion 13 protrudes to the left and right outer sides of the wound tube packaging container body 22, and as described later, the wound tube package The lid 23 can be locked in the container 21.

  As shown in FIG. 4, the depth of the folded piece 12 (the length in the depth direction of the wound tubular packaging container body 22) is set to D4, the depth D of the rolled tubular packaging container body 22 (side plate 8). When the width of the piece 12 (the length in the left-right direction of the wound tube packaging container body 22) is represented by W, the folded piece 12 does not receive the wound tube body 26, and the relational expressions (1) to ( It is formed so as to satisfy 3). Further, in the state in which the wound cylindrical body 26 is accommodated, it is formed so as to satisfy the relational expressions (4) to (6) in addition to the relational expressions (1) to (3). The folding piece 12 is preferably formed so as to satisfy a ratio of D: D4: W = 40: 19: 15 from the viewpoint of engagement force and ease of use.

When the height (inside dimension) H of the cylindrical casing container 21 is converted to a state of 38, when D4> 19 (H / 38), the folded piece 12 becomes large, so that it was wound around the core body 26a. When the content is pulled out, the content comes into contact with the folded piece 12, and it becomes impossible to obtain the object that is the effect of the present invention. In the case of D4 <17.3 (H / 38) when converted in the same manner as described above, the folding piece 12 becomes smaller and the engaging protrusion 13 connected also becomes smaller, so that the performance, shape and strength cannot be maintained, and the present invention described above. The effect of cannot be obtained.
Further, as the height (inner dimension) H of the winding tube packaging container 21 becomes larger (higher), a space (gap) is likely to be formed between the winding tube packaging container 21 and the winding tube body 26 relatively. In this case, a larger width of the folded piece 12 is preferable from the viewpoint of preventing the winding tube body 26 from jumping out. For this reason, a quadratic term consisting of the variable H is provided in the formula (1), and correction is performed so that the value of the quadratic term consisting of the depth D4 of the folded piece 12 is appropriate.

When the height (inner dimension) H = 38 and W> 20, the folded piece 12 comes into contact with the lid body 23 from the initial stage of closing the lid body 23 and is folded into the inner side of the cylindrical packaging container body 22. The engaging protrusion 13 connected to the folded piece 12 protrudes to the outside of the wound tube packaging container main body 22. As a result, the lid 23 is difficult to close, and the user cannot obtain the effects of the present invention. For this reason, when the height (inner dimension) H = 38, W ≦ 18 is preferable. When the value of W is smaller than the values of the relational expression (1) and the relational expression (4), the angle formed between the folding piece 12 and the side plate 8, that is, the angle formed between the engagement protrusion 13 and the side plate 8 is approximately 90. The function of the engagement protrusion 13 that the engagement protrusion 13 engages with the engagement portion 20 and locks the lid body 23 cannot be ensured. At the same time, since the width of the folded piece 12 is too short, the winding tube packaging container 21 cannot obtain the effect of preventing the winding tube 26 from popping out.
Further, the width W of the folded piece 12 is likely to approach the folded piece 12 as the outer diameter S of the core body 26a increases, so that the winding cylinder body 26 can be prevented from popping out even if the width W is reduced. it can. For this reason, the coefficient of the variable S in Expression (4) is a negative value, and is defined from a viewpoint different from Expression (1) so that the value of the width W of the folded piece 12 decreases as the outer diameter of the core increases. doing. On the other hand, the smaller the outer diameter S of the core body 26a, the more easily the core body 26a is separated from the folded piece 12, so it is preferable to increase the core body 26a to prevent the winding cylinder body 26 from popping out. For this reason, in Formula (4), it defines from the viewpoint different from Formula (1) so that the value of the width W of the folding piece 12 may become large, so that the outer diameter of a core body becomes small.

(Engagement protrusion)
The winding cylinder packaging container 21 employs an engaging projection 13 connected to the folding piece 12 as means for locking the lid body 23 to the winding cylinder packaging container main body 22. Thus, according to the present invention, the engagement projection 13 of the wound tube packaging container main body 22 can be engaged with the lid body 23 with a predetermined size, so that the lid body 23 does not open in normal use. In addition, when the user takes out the wound tube body 26 (the core body 26a around which the contents are wound) from the wound tube body packaging container 21 for some reason, the user is formed with a predetermined size. However, it does not become difficult to take out the winding tube body 26 and the like from the winding tube body packaging container 21.

  Various methods are conceivable for the method of providing the engaging protrusions that protrude outwardly from the left and right sides of the winding tube body 22. Among them, in the present invention, the engagement protrusion 13 is formed by a cut line 19 formed on a fold line 37 that is a boundary between the side plate 8 and the fold piece 12 as shown in FIG. As shown in FIGS. 1A and 1B and FIG. 5, when the folded piece 12 is folded to the inner side of the wound packaging body 22 according to the folding line 37 shown in FIG. 3, a part on the side plate 8 side is included. The engaging projections 13 formed on the left and right side plates 8 of the wound tube packaging container main body 22 protrude from the left and right side plates 8. Considering the ease of opening and closing of the lid 23 and the locking force by the engaging protrusion 13, the shape of the engaging protrusion 13 is preferably a trapezoid with a narrow width toward the extending end 16. More preferably, it is an isosceles trapezoid.

Specifically, as shown in FIG. 4, when the extended end 16 of the engaging protrusion 13 is represented by D2, the length of the base of the engaging protrusion 13 is represented by D3, and the depth of the folded piece 12 is represented by D4, the following relational expression ( 7) It is preferable to satisfy the relational expression (8).
(1/3) D4 ≦ D2 ≦ (1/2) D4 Formula (7)
(1/2) D4 ≦ D3 ≦ (2/3) D4 Formula (8)

  The ratio of the engagement protrusions 13 may be D: D2: D3 = 40: 7: 11 when the depth D of the wound tube packaging container body 22 is 40.

  In D3> (2/3) D4, the width of the connecting portion between the side plate 8 and the folding piece 12 is shortened due to the relationship with the depth D4 of the folding piece 12, so that the strength of the folding piece 12 cannot be maintained, and at the same time, the engagement protrusion The strength of 13 cannot be maintained. When D3 <(1/2) D4, the length D3 of the base portion of the engagement protrusion 13 becomes short, and the strength of the engagement protrusion 13 cannot be maintained.

  In D2> (1/2) D4, the shape of the engagement protrusion 13 tends to be close to a square, and the angle between the extended end 16 of the engagement protrusion 13 and the oblique side of the engagement protrusion 13 approaches an acute angle. It becomes impossible to obtain the ease of opening the lid 23. In D2 <(1/3) D4, the engagement area between the extended end 16 of the engagement protrusion 13 and the upper end 17 of the auxiliary side cover plate 11 is reduced, and the engagement force of the cover body 23 is reduced.

  The height H2 of the engaging projection 13 is defined as H2 when the height of the engaging projection 13 (the length in the longitudinal direction of the wound tube packaging container body 22) is T2, and the thickness of the paper plate of the wound tube packaging container 21 is T2. In consideration of the strength of the engaging protrusion 13, the protruding amount, and the thickness of the side plate 8 of the wound tubular packaging container body 22, it is preferable that H2 ≦ 7T2. The height H2 of the engaging protrusion 13 is more preferably D: H2 = 40: 3. Further, when the height H2 of the engagement protrusion 13 is divided by the folding line 37 for reasons such as the above strength, the ratio of the extension end 16 side of the engagement protrusion 13: the base side of the engagement protrusion 13 = 2: 1. Is more preferable.

As shown in FIGS. 3 and 4, the arrangement of the engagement protrusion 13 with respect to the side plate 8 is preferably such that the vertical bisector of the engagement protrusion 13 coincides with the vertical bisector L of the side plate 8. Further, the center of the core body 26 a passes through the vertical bisector L of the side plate 8.
The length of the engagement protrusion 13 protruding from the side plate 8 is preferably 1 to 3 mm.

When the engaging protrusion 13 is arranged to be biased toward the rear plate 3, the engaging force of the engaging protrusion 13 with respect to the lid body 23 is weakened, and the lid body 23 of the wound tube packaging container 21 is constant during and after use. It becomes impossible to obtain a state where it becomes difficult to open due to the locking force.
On the contrary, if the engagement protrusions 13 are arranged so as to be biased toward the front plate 1, the engagement force of the engagement protrusions 13 with respect to the lid body 23 becomes excessively strong, and the contents are rewound onto the core body 26a. It becomes difficult to open the lid 23.

[Lid]
As shown in FIGS. 1 (a) and 1 (b), the lid body 23 of the cylindrical packaging container 21 is connected to the long side of the rear plate 3 of the cylindrical packaging container body 22 and faces the bottom plate 2. A lid plate 4 having a rectangular shape, a front plate 5 connected to the long side of the lid plate 4, facing the front plate 1, and depending from the lid plate 4, and a rectangular shape. 4 is connected to the left and right short sides, and faces the side plate 8 and hangs down from the cover plate 4. The side cover plate 10 is rectangular or square in shape, and is connected to the left and right short sides of the front cover plate 5. It is formed on each surface of the auxiliary side cover plate 11 having a rectangular or square shape. The cover body 23 covers the upper opening part facing the bottom plate 2 of the wound tubular package container main body 22 so that it can be opened and closed.

  The lid 23 is further provided with a temporary fastening piece 6 connected to the long side facing the long side connected to the cover plate 4 of the front cover plate 5 when the contents are shipped (FIGS. 2 and 8 (a)). )reference). The temporary fastening piece 6 is used to seal the winding tube packaging container 21 at the time of shipment, distribution, etc. of the contents (product) of the winding tube packaging container 21, and the inner surface (back surface) of the front lid plate 5 or the front. It is provided so as not to expose the cutting tool 25 provided on the outer surface (front surface) of the plate 1, and is bonded to the outer surface of the front plate 1 of the wound tube packaging container body 22 to attach the lid 23 to the wound tube package container body. 22 is fixed. The temporary fastening piece 6 is not bent at the long side connected to the front lid plate 5, and the temporary fastening piece 6 can be easily separated from other portions of the wound tubular packaging container 21 such as the front lid plate 5 and the front plate 1. Therefore, a notch such as a broken line is formed along the long side.

  The lid body 23 is connected to the wound tube packaging container main body 22 at the long side on the rear side of the cover plate 4, and is configured to be able to open and close the opening of the wound tube packaging container body 22 with the long side as a hinge. Specifically, when the lid body 23 of the winding cylinder packaging container 21 is closed (see FIG. 1B), the lid body 23 is wrapped in a winding cylinder body so that the outer shape of the winding cylinder packaging container 21 is a rectangular parallelepiped. When the wound tubular packaging container 21 is opened (see FIG. 1 (a)), the upper portion of the wound tubular packaging container body 22 is completely opened when the tubular tubular packaging container 21 is opened. 26 can be operated, accommodated or removed.

  The shape of the lid 23 can cover the upper opening of the cylindrical packaging container body 22, and the user pulls out the contents wound around a cylindrical core body 26 a described later from the cylindrical packaging container 21. Provided is a shape that does not hinder cutting with the cutting tool 25, and a portion (engagement portion 20) where the lid 23 and the engagement protrusion 13 of the above-described wound cylindrical body 14 are engaged. Satisfy the requirement that you can.

The angle formed by the front lid plate 5 constituting the lid body 23, the side lid plate 10 and the auxiliary side lid plate 11 is such that the lid body 23 and the engaging projection 13 are engaged with each other, and the contents are wrapped in the cylindrical packaging container 21. It is preferable that the angle is approximately 90 degrees with respect to each other in consideration of the cutting and cutting with the cutting tool 25 and the shape of the wound tube packaging container main body 22.
The angles formed by the front cover plate 5 and the cover plate 4, the side cover plate 10, and the auxiliary side cover plate 11 and the cover plate 4 are each preferably approximately 90 degrees.

  Furthermore, in order for the lid body 23 to ensure the function as a lid of the wound body packaging container main body 22 and when the cutting tool 25 is provided on the lower back surface of the front lid plate 5, the cutting tool 25 suitably uses the contents. In order to cut, the height of the front cover plate 5 (the length in the short side direction) is about 1 / 2H2 or more of the height H2 of the wound tube packaging container body 22 (height of the wound tube package 21). The following is preferable.

(Engagement part)
Various configurations of the engaging means of the engaging protrusion 13 and the lid body 23 can be considered. From the relationship with the locking force of the engaging protrusion 13 to the lid body 23, the auxiliary side lid plate 11 and the side lid plate 10 The engaging part 20 formed by bonding was employed.

As shown in FIG. 1B, FIG. 5 and FIG. 6, on the side surface of the lid 23, as described above, the side lid plate 10 and the auxiliary side lid plate 11 have the side lid plate 10 formed of a wound cylinder packaging container. The auxiliary side cover plate 11 connected to the front cover plate 5 on the outer side of the front cover plate 5 is attached in a folded state so as to be positioned inside the wound tube packaging container 21. At this time, the auxiliary side cover plate 11 has an upper end 17 of the auxiliary side cover plate 11 spaced from a ridge line (short side of the cover plate 4) between the cover plate 4 and the side cover plate 10 inside the cover body 23. It is formed in the shape to be arranged. This interval has a recess having a depth corresponding to the plate thickness T2 of the auxiliary side cover plate 11 (winding tube packaging container 21), and engages with the engagement protrusion 13 of the winding tube packaging container body 22 as the engaging portion 20. To do. The distance (the size of the gap) between the upper end 17 of the auxiliary side cover plate 11 and the ridgeline between the cover plate 4 and the side cover plate 10 so that the engagement portion 20 can engage and disengage the engagement protrusion 13. The thickness of the engagement protrusion 13 is greater than the thickness T2 (the thickness T2 of the wound tubular packaging container 21). Furthermore, it is preferable that the upper end 17 of the auxiliary side cover plate 11 is substantially parallel to the ridge line between the cover plate 4 and the side cover plate 10.
Further, from the viewpoint of securing the locking force, it is preferable that the extending end 16 of the engaging protrusion 13 and the upper end 17 of the auxiliary side cover plate 11 are on the same straight line.

[Winding cylinder]
Next, the winding cylinder body 26 accommodated in the winding cylinder packaging container 21 will be described.
The content of the roll packaging container 21 is not limited as long as it is a metal foil such as an aluminum foil, various resin wraps, or a sheet-like material such as cooking paper, and a hollow cylindrical (circular tube) core. The wound body 26 is housed in the wound body packaging container 21 as a wound body 26 wound around the peripheral surface of the body 26a. Therefore, the outer shape of the wound tube body 26 is also cylindrical, the length of the shaft is substantially the same as the core body 26a, and the outer diameter in a side view depends on the thickness of the contents and the wound length. It becomes larger than the outer diameter S of 26a. When the thickness of the content wound around the winding cylinder 26 is T, the outer diameter of the winding cylinder 26 is represented by (S + 2T) (see FIG. 4).

  The minimum requirement is that the size of the winding cylinder 26 is within a range that can be accommodated in the winding cylinder packaging container 21 (winding cylinder packaging container body 22). In addition, if the outer diameter of the winding tube body 26 is too small with respect to the winding tube body 22, the winding tube body 21 is likely to be deformed and the usability is deteriorated. For this reason, the winding cylinder 26 needs an appropriate size. Further, if the outer diameter of the winding cylinder 26 is small, pressure is applied to the folded piece 12, which may weaken the engagement force of the engagement protrusion 13 with respect to the lid body 23. On the other hand, when the outer diameter of the winding tube body 26 becomes too large with respect to at least one of the height (inner dimension) H or the depth (inner dimension) D1 of the winding tube body 22, the contents are pulled out. When the inner surface of the winding tube packaging container 21 comes into contact with the inner surface of the winding tube body 26, the rotation of the winding tube body 26 is deteriorated, and the contents are hardly taken out. For this reason, when the height (inner dimension) H and the depth (inner dimension) D1 of the wound tube packaging container 21 are 38 mm, the outer diameter of the wound tube body 26 is preferably 34 mm or less.

(Core)
The core body 26a for storing the contents in the wound tube packaging container 21 according to the present invention winds and fixes the sheet-like contents around its peripheral surface, and therefore has a certain degree of strength such as cardboard and plastic plate. The material is preferably made of a material having no limitation on the material, but is particularly preferably made of paper that can be easily discarded and recycled.
Since the winding cylinder 26 is obtained by winding the contents around the core body 26a, not only the size of the winding cylinder body 26 itself but also the size of the core body 26a is important.
If the outer diameter S of the core body 26a is small, as a result, the inner diameter of the core body 26a becomes smaller, so that the pop-out preventing means provided at the left and right ends of the wound body packaging container body 22 of the wound body packaging container 21 described later. 45 cannot be physically provided. On the contrary, when the outer diameter S of the core body 26a is increased, the core body 26a has a size that can accommodate the winding tube body 26 in the winding tube body packaging container 21, and as a result, the content amount (length) decreases. .

Moreover, the length of the content wound around the core body 26a has a physical and technical limit. Furthermore, the thickness of the aluminum foil or the like as the contents becomes a certain thickness depending on the purpose of use, manufacturing technique, and physical properties. Therefore, the contents wound around the core body 26a have a certain thickness T.
The outer diameter of the winding cylinder 26 is represented by (S + 2T). Here, when the content is excessively wound around the core body 26a and secured (when the thickness T is excessive), the outer diameter (S + 2T) of the winding cylinder body 26 increases and the winding cylinder packaging container 21 It will be difficult to pull out the contents by touching the inner surface.

When the ratio (S / H) of the outer diameter S of the core body 26a to the height (inner dimension) H of the wound tube packaging container body 22 is large, specifically, the ratio (S / H)> 0.9. The contents cannot be sufficiently wound around the core body 26a.
On the other hand, if the outer diameter S of the core body 26a is too small with respect to the height (inner dimension) H of the wound cylindrical packaging container body 22, specifically, if the ratio (S / H) ≦ 0.625, The gap between the cylindrical packaging container 21 and the accommodated winding cylindrical body 26 is too wide, and the winding cylindrical packaging container 21 is easily deformed, and the object of the present invention cannot be achieved. Furthermore, since the inner shape of the core body 26a is too small, the winding cylinder body 26 cannot be fixed by the pop-out prevention means 45 of the winding cylinder packaging container 21 as described above.
Accordingly, the ratio (S / H) of the outer diameter S of the core body 26a to the height (inner dimension) H of the wound tube packaging container body 22 is preferably 0.625 <(S / H) ≦ 0.9, The range of 0.7 ≦ (S / H) ≦ 0.8 is more preferable, and the outer diameter S of the core body 26a is determined so as to obtain such a ratio.
If the depth (inner dimension) D1 is too long, the gap between the wound tube packaging container 21 and the accommodated wound tube body 26 is too wide as in the case of the height (inner size) H, and the wound tube package The container 21 is easily deformed. For this reason, 0.625 <(S / D1) ≦ 0.9 is also preferable for the depth (inside dimension) D1 of the wound tube packaging container body 22, and 0.7 ≦ (S / D1) ≦ 0.8. The range is more preferable, and the outer diameter S of the core body 26a is determined so as to have such a ratio.

(Contents)
The content wound around the core body 26a accommodated in the wound tube packaging container 21 is not particularly limited, such as metal foil such as aluminum foil, various plastic wraps, and cooking paper.

[Cutting tool]
As shown in FIG. 1 and FIG. 2, in order to cut after winding a necessary amount of contents such as aluminum foil wound around the core body 26 a from the winding body packaging container 21 in the winding body packaging container 21. The cutting tool 25 and the pop-out prevention means 45 are preferably provided.
The shape of the cutting tool 25 can be any shape as long as it achieves its purpose, such as a straight line or a V shape. As the material of the cutting tool 25, any material such as metal, paper, resin-impregnated paper or the like can be used as long as the purpose is achieved. In consideration of disposal and recycling of the wound tubular packaging container 21 after use, the cutting tool 25 is preferably made of paper or resin-impregnated paper. In particular, considering cutting performance such as aluminum foil as the contents, the cutting tool 25 is preferably made of resin-impregnated paper in which acrylic resin is impregnated into pulp.

  The cutting tool 25 may be provided at any position such as the lower end of the front lid plate 5, the upper end 14 of the front plate 1, the ridge line portions of the front plate 1 and the bottom plate 2. Considering prevention of damage due to the contents coming into contact with the cutting tool 25 when the contents such as aluminum foil are pulled out from the roll packaging container 21, and prevention of unwinding of the contents to the core 26a after the contents are cut. Then, it is preferable that the cutting tool 25 is provided along the lower end back surface of the front lid plate 5 or the ridgeline between the front plate 1 and the bottom plate 2. Considering the balance between the contamination of the contents and the size of the lid 23, it is more preferable that the cutting tool 25 is provided on the back surface of the lower end of the front lid plate 5.

[Jump prevention means]
In order to prevent the winding tube packaging container 21 from popping out from the winding tube packaging container main body 22 together with the core body 26a (winding tube body 26) around which the content such as aluminum foil is wound when the stored contents are pulled out. Further, it is preferable to provide the pop-out preventing means 45 (see FIGS. 1A and 1B). The pop-up preventing means 45 is provided so as to protrude inward from the left and right ends of the wound tube packaging container body 22, and is engaged with the hollow portion of the core body 26a from the left and right sides of the core body 26a. 26 is fixed to the wound tube packaging container body 22 to such an extent that it can rotate freely. In FIG. 2, the pop-out prevention means 45 forms a substantially U-shaped cut line 41 at the approximate center of the side surface 8 of the cylindrical tube packaging container body 22, that is, the side plate 8 forming the side surface. It is formed by bending inside the wound tube packaging container body 22.

  Further, the cut line 42 and the folding line 44 are formed at the same position and shape on the second auxiliary side plate 9 that is overlapped with the side plate 8. On the other hand, the first auxiliary side plate 7 sandwiched between the side plate 8 and the second auxiliary side plate 9 is formed in a shape excluding the position of the pop-out prevention means 45. By being configured in this way, the pop-out preventing means 45 is easily formed by pushing the side surface (side plate 8) from the outside of the wound tube packaging container body 22 as will be described later. The pop-out preventing means 45 is not limited to this, and may be formed only on the second auxiliary side plate 9 disposed on the innermost side of the side surface of the wound tube packaging container main body 22, for example.

  As described above, with respect to the wound tubular packaging container 21, specific formulas and the like regarding the height (inner dimensions) and depth of the rolled tubular package container main body 22 (side plate 8), the sizes of the folding pieces 12 and the engagement protrusions 13, and the like. Although the present invention has been described with numerical values, the present invention can also be applied to similar shapes in which the height (inner dimensions) and depth of the wound tube packaging container body 22 (side plate 8) are at least 50 mm each.

<Operation of the wound cylindrical packaging container>
Next, an operation for taking out the contents stored in the wound tubular packaging container 21 will be described.
A user (consumer) who has purchased an aluminum foil or the like packaged in a winding tube packaging container 21 first detaches the temporary fastening piece 6 from the front cover plate 5 at the same time as using the front plate 1 at the first use. It peels off and the winding cylinder packaging container 21 is opened. When the temporary fixing piece 6 is cut off, the lower end of the rear surface of the front lid plate 5 or the cutting tool 25 provided on the front plate 1 is exposed. At this time, the lid body 23 is fixed to the winding body packaging container body 22 by the engagement protrusions 13 of the winding body packaging container body 22 being locked by the engaging portion 20 inside thereof.

  Next, the user causes the lid 23 by hand to cause the connecting portion (ridge line between the lid plate 4 and the rear plate 3) to be connected to the wound tube packaging container body 22 as a rotation axis. Due to the force that is caused, the engaging protrusion 13 is detached from the engaging portion 20, the fixing of the lid body 23 to the winding tube packaging container body 22 is released, and the winding tube packaging container 21 is opened.

  Then, the user peels off the end of the contents from the surface of the winding tube body 26 accommodated in the winding tube body 22, and the contents are removed from the winding tube body 26 on the front plate of the winding tube body 22. 1 is pulled out along the outer surface of 1 and the amount (length) to be taken out of the contents is peeled off from the winding tube body 26 and pulled out of the winding tube body 22.

  Furthermore, the user puts the lid body 23 on the wound tube packaging container body 22 and closes the wound tube package container 21. Due to the movement of the lid body 23, the extended end 16 of the engagement projection 13 of the winding cylinder packaging container body 22 slides on the inner side surfaces of the lid body 23 (the inner surface of the auxiliary side lid plate 11 and the inner surface of the side lid plate 10). After moving, it engages with the engaging portion 20, and at this time, the user feels a so-called light hand. When the engaging protrusion 13 is locked by the engaging portion 20, the lid body 23 is again fixed to the wound tube packaging container body 22.

  Finally, the user prepares at the lower end of the back surface of the front lid plate 5 while maintaining the state in which the contents are sandwiched in the gap between the front plate 1 of the wound tube packaging container body 22 and the front lid plate 5 of the lid body 23. The contents are cut while holding the contents with the cutting tool 25. After the cutting, the engaging protrusion 13 engages with the engaging portion 20 to maintain the locking force, so that the lid body 23 does not open even if the user releases his / her hand from the lid body 23. For this reason, after use, the contents such as the aluminum foil packaged by the wound tube packaging container 21 are not soiled.

  An operation when the user uses an aluminum foil or the like packaged by the wound tubular packaging container 21 from the second time on will be described.

Since the engagement protrusion 13 is engaged with the lid body 23 with an appropriate locking force at the engagement portion 20 (the upper end 17 of the auxiliary side lid plate 11) composed of the auxiliary side lid plate 11 and the side lid plate 10, the previous time In many cases, the contents after use remain in the gap between the front plate 1 of the wound packaging body 22 and the front cover plate 5 of the lid 23.
When the contents can be pulled out from the gap between the front plate 1 and the front lid plate 5, the user pulls out the necessary amount from the gap without opening the lid 23. And a user cuts with the lower end of the back of the front lid plate 5 while maintaining the state in which the contents are sandwiched in the gap between the front plate 1 of the cylindrical packaging container body 22 and the front lid plate 5 of the lid 23. The contents are cut while holding the contents with the tool 25.

On the other hand, after the previous use, when the contents have been rewound around the core body 26a, or the contents remain in the gap between the front plate 1 of the cylindrical packaging container body 22 and the front cover plate 5 of the lid body 23. When the contents cannot be pulled out from the gap, the user may perform the operation by causing the lid 23 to be manually connected to the winding tube packaging container body 22 as the rotation axis.
Thereafter, the contents are cut and used by using the wound tube packaging container 21 by the same procedure as that for the first use.
Even in this case, since the engaging protrusion 13 has an appropriate locking force with respect to the lid 23, the user does not have difficulty in opening the lid 23. Further, it is not difficult for the user to close the lid 23.

<Manufacturing method of the wound tube packaging container>
The process for implementing the manufacturing method of the winding cylinder packaging container which accommodated the winding cylinder which wound the sheet-like member based on this invention inside is demonstrated.
As shown in FIG. 7, the method for manufacturing the wound tube packaging container is roughly divided into an alignment step 101 for aligning the folded paper plate 51 obtained by folding the flat paper plate 50 cut into a developed shape of the wound tube packaging container 21. The feeding step 102 for feeding the folded paper board 51 to the assembly feeding path by the feeding mechanism 61, the ridge line of the folded paper board 51 is pressed by the conveyor mechanism 70 having the protruding piece 71, etc. to form a rectangular tube, and the opening 53 is formed. A forming step 103 to be formed, a storing step 104 for storing the winding cylinder 26 inside the rectangular tube-like folded paper board 52 (folding paper board 51 having the opening 53) by an arm mechanism, a folding mechanism 62, and a folding guide. 63, and a sealing step 105 that folds and seals both open ends of the rectangular tube-shaped folded paper board 52 to form the wound tube packaging container 21.

(Alignment process)
In the aligning step 101, the flat paper board 50 cut into a developed shape of the wound tube packaging container 21 as shown in FIG. 9 (a) is temporarily fixed as shown in FIGS. 8 (a) and 9 (b). This is a step of aligning the folded sheet board 51 in a folded state with the long sides facing each other after temporarily fixing 6 and then folding the sheet.
Specifically, as shown in FIG. 8 (a), a flat paper board 50 (FIG. 9 (a)) cut into a developed shape of the cylindrical packaging container 21 is temporarily fastened with a temporary fastening piece 6 and the winding. Folded paper board 51 is folded so that the inner surface side of front plate 1 and inner surface side of cover plate 4 face each other, and the inner surface side of bottom plate 2 and the inner surface side of rear plate 3 face each other. This is a step of aligning the folded surfaces (outer surfaces) (FIG. 9B) by an alignment mechanism 60 such as a conveyor.
By aligning the folded paperboards 51 in this way, the folded paperboards 51 can be sent out to the sending step 102 quickly and accurately, and in the forming step 103, the folded paperboards 51 can be quickly formed into a rectangular tube shape. It becomes possible.

  When performing the alignment step, an alignment mechanism 60 such as a conveyor is used. The alignment mechanism 60 has a placement surface on which the folded paper board 51 is placed, and the placement surface has an inclination so as to move downward according to gravity. Above the placement surface, a guide for aligning the folding paper plates 51 having a minimum interval in the major axis direction of the folding paper plates 51 and a minimum height of the folding paper plates 51 are provided. A guide for aligning the folded paper board 51 having the above is provided. Further, a feeding mechanism 61 for folding paper board 51 is provided at the lower end (end) of the placement surface.

(Sending process)
As shown in FIG. 9C, the sending process 102 is performed by feeding the folded folded paper plates 51 one by one by the rotation of the feeding mechanism 61 so that the folded folded paper plates 51 are placed on the assembly feeding path. This is a process of passing the conveyor mechanism 70 upward.
Specifically, when the folded paper board 51 aligned in the aligning step 101 is sent to a position where the folded paper board 51 is brought into contact with the delivery mechanism 61, the delivery mechanism 61 rotates to convey the folded paper board 51 to the conveyor mechanism on the one-sheet assembly feed path. 70 is sent out from above. The feeding mechanism 61 includes a plurality of projecting pieces 71 projecting from the conveying belt 72 at a predetermined interval on the ridge line side composed of the front cover plate 5 and the bottom plate 2 of the folded paper board 51, and between the projecting pieces 71 of the conveyor mechanism 70. Operates to send out.

  The delivery mechanism 61 used in the delivery step 102 has an operation rotation shaft, rotates the rotating body, and rotates the operation rotation shaft when the folded paper board 51 sent from the alignment mechanism 60 contacts the rotation body. Then, the folding paper board 51 is sent out from above the conveyor mechanism 70 to a position between the protruding pieces 71 of the conveyor mechanism 70.

(Formation process)
The forming step 103 is a step of making the folded paper plate 51 into a rectangular tube shape as shown in FIG. In the forming step 103, the ridge lines at both the upper and lower ends of the folding paper board 51 are pressed by the conveying belt 72 of the conveyor mechanism 70 and the guide 73 installed above the conveyor mechanism 70 at a predetermined interval, and the distance between the paperboards of the folding paper board 51 is determined. Is expanded into a rectangular tube shape and the opening 53 is formed.

  The conveyor mechanism 70 used in the forming step 103 includes a conveyor belt 72 that supports and moves the lower surface of the folded paper board 51 and the like. The conveyor belt 72 is provided with protruding pieces 71 at predetermined intervals, and faces the conveyor belt 72. A guide 73 is provided at a position to be operated. The projecting piece 71 moves the folding paper board 51, forms an opening 53 in the folding paper board 51, and supports both sides of the folding paper board 51 in the forward and backward directions along the traveling direction. Located in. The protruding pieces 71 are installed at positions on the front and rear sides of the folding paper board 51, one on each side.

  The specific operation in the forming step 103 is that the folded paper board 51 sent between the protruding pieces 71 of the conveyor mechanism 70 is moved on the assembly feed path by the conveyor mechanism 70 in the traveling direction. The folded paper plate 51 is transferred to the protruding piece 71 at the position of the conveying belt 72 on the curved surface of the pulley, so that the protruding piece 71 is held in the linear position while being held by the conveying belt 72, the guide 73, and the protruding piece 71.
