Description

  The present invention relates to a storage box for a wound tubular body in which a wrap film for food packaging, aluminum foil, or the like is wound. In particular, the winding cylinder box prevents the winding cylinder from popping out when the film is pulled out, and when removing the winding cylinder from the storage room for some reason, such as recovery from trouble during use by the consumer or disposal of the core. It is related with the storage box of the winding cylinder which harmonized the ease of taking out from the container.

  Conventionally, a wrap film and an aluminum foil are stored in a box as a cylindrical body wound around a core, and a necessary amount is cut and used by a saw blade attached to a drawer storage box. At that time, the winding cylinder may not be smoothly rotated in the storage box, or the winding cylinder may jump out of the box due to factors such as a pulling speed and resistance due to adhesion between the wrap films. As a means for preventing these, for example, in Patent Document 1, a retaining piece that can be inserted inside the core end portion of a roll-like material is provided on the end box of the packaging box, and when the roll diameter becomes smaller and lighter, A method has been disclosed for preventing the matter from easily coming out of the packaging box and making the drawing operation difficult. Further, in Patent Document 2, the dimensions of the support member and the like are specified to prevent the winding cylinder from jumping out of the storage chamber, and in particular, the wrap film is made into a long winding by reducing the diameter of the winding cylinder. And a method of preventing loose rotation at the time of pulling out, which is likely to occur when the outer diameter of the wound cylindrical body becomes sufficiently smaller than the depth width of the bottom plate due to consumption of aluminum foil and aluminum foil.

  In Patent Document 3, the ratio of the crease length of the support member to the maximum width of the support member, the height from the bottom plate of the window, the ratio of the depth width of the storage chamber to the outer diameter of the core, A method is disclosed in which a range is clearly defined for the dimensions of the gap in the longitudinal width direction of the wound tubular body, and the ability to prevent the wound tubular body from popping out and the ease of taking out the wound tubular body from the storage box are disclosed. .

  Further, in Patent Document 4, a tongue piece is provided which is folded at the inner flap of the side plate with a crease and located inside the paper tube, and the crease is disposed obliquely with respect to the horizontal direction of the carton. A method has been disclosed in which a paper tube is held so as not to jump out against a light pull, and can be easily inserted and removed, and it is restored to its original state even if it is repeatedly taken out and its function is not impaired. Further, in Patent Document 5, an inner locking piece and an outer locking piece configured to be bent inward by a broken line are provided on a main body inner plate and a main body side plate, and the bent line is vertical or inclined (perpendicular to the bottom plate). A method of preventing the protruding portion from being easily returned to the original by making the engaging portion having an angle with the line in the range of 0 to 50 degrees and preventing the popping out reliably is disclosed. Yes.

  However, the technique in which the retaining piece is not fixed as in Patent Document 1 described above hardly causes a problem that the retaining piece is damaged when the roll-shaped object is taken out. However, the pressed retaining piece has strength. Therefore, when it is pulled out vigorously, the retaining piece bends 90 degrees or more with respect to the side plate, and there is a problem that the roll-out cannot be prevented sufficiently. Further, in the technique of Patent Document 2, since the cylindrical inner diameter and the maximum width of the support member are almost the same size, the winding cylinder has a high ability to prevent popping out and free rotation, but it can be wound during troubles during use. There is a problem that a large force is required to take out the cylindrical body. Further, in the technique of Patent Document 3, by providing a gap between the winding cylinder and the storage box and between the winding cylinder and the support member for easy removal, in a severe usage method outside the assumed range, for example, There is a problem that a sufficient ability to prevent popping out cannot be maintained when pulling upward with respect to the opening of the storage box or pulling out at a high pulling speed. In addition, the technique of Patent Document 4 has the ability to take out and prevent popping out against pulling upward on the carton, but when the consumer actually pulls out the wrap film stored, it is not on the carton but on the diagonally upper side. If the paper tube is lifted and there is a problem that it does not exhibit sufficient pop-out prevention performance, and if the weight of the winding cylinder is heavy at the start of use, the length of the crease and the area of the tongue piece relative to the paper tube Since it is insufficient, it does not have a sufficient function to prevent the paper tube from popping out in the packaging web drawer. Moreover, in the locking piece which gave the inclination which made the front-plate side the upper end and the rear-plate side the lower end like patent document 5, the inner locking piece which provided 0-50 degree | times inclination with respect to the perpendicular line of a bottom plate Therefore, it has a very effective pop-out prevention performance in the pull-out direction, but it requires a large force to take out the winding cylinder during troubles during use, etc. There is a problem of end up.

  From the conventional invention, in the support member connected to the side wall of the storage box provided to prevent the winding cylinder from popping out of the storage box, the shape of the support member is increased or fixed in order to improve the pop-out prevention performance. If the fold line is inclined or the fold line is greatly inclined, it is difficult to take out the wound cylinder body in the event of trouble, etc., and the hand touches the cutting saw blade attached to the storage box lid, or the support member takes out. There is a high possibility of breakage due to the load applied sometimes. On the other hand, if the supporting member is made small in order to make it easy to take out the wound cylindrical body, the pop-out preventing performance at the time of drawing out the film or the like is lowered, and it becomes easy to pop out. Thus, there is a trade-off between ease of taking out and ability to prevent popping out.

  The present invention provides a balance between ease of taking-out of the cylindrical tube and difficulty of popping out for use by consumers by means of a support member that prevents the cylindrical tube from popping out without any problem in the drawability of the film, etc. An object of the present invention is to provide a wound tube storage box in which a support member or the like is not damaged.

In order to solve the above-mentioned problem, the present inventor considers the fold line inclination angle of the support member of the winding cylinder storage box, and realizes that the two conflicting performances of the pop-out prevention performance and the take-out performance are compatible and harmonized. The headline and the present invention were made.
That is, the present invention relates to a storage chamber 12 having an open top formed by the front plate 1, the bottom plate 2, the rear plate 3, the side plate 8, and the auxiliary side plates 9, 9 ', and the rear of the storage chamber 12. A lid plate 4 that can be opened and closed from the upper edge of the plate 3 and that is connected in a direction covering the storage chamber 12; a lid lid piece 5 extending from the front edge of the lid plate 4 in a direction covering the front plate 1; And a rectangular parallelepiped box body formed of a lid 13 formed on each surface of the auxiliary lid piece auxiliary side plate 11 and a wound cylindrical body R stored in the storage chamber 12. A support member 14 'which can be inserted into the inside of R and supports the winding cylinder R is formed by a cut line and a fold line or a half cut line, and is stored in the side plate 8 via the fold line or the half cut line. In a winding cylinder storage box that can be pushed into the chamber 12 and has a window 14 for inserting a support member 14 ′ into the winding cylinder R. The folding line or half-cut line forming the support member 14 ′ is provided with an inclination having the front plate 1 side as an upper end and the rear plate 3 side as a lower end, and is a straight line parallel to the bottom plate 2. an angle θ formed by, Ri range der of 4 ° or more 12 ° or less, the breakage lines forming the support member (14 '), the lower side of the support member (14') of the fold line or semi-broken line It is a winding cylinder storage box characterized by being located in.
Further, in the above-described wound cylinder storage box, when the maximum horizontal width of the support member 14 'is L, the fold line horizontal width is S, the maximum vertical width is H, and the inner diameter of the core R1 is D. 5 ≦ L / D ≦ 0.7 1 type 0.4 ≦ S / D ≦ 0.64 2 type 0.4 ≦ H / D ≦ 0.7 3 conditions are satisfied. It is a storage box.

  The winding cylinder storage box according to the present invention is provided with a specific inclination angle within a range of the folding line of the support member, so that the ease of taking out the winding cylinder that has occurred in the support member with a conventional inclination is reduced, that is, the extraction is performed. There is an effect that it is possible to improve only the pop-out prevention performance of the winding cylinder without increasing the force.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a three-dimensional schematic view of a state in which the support member of the winding cylinder storage box of the present invention is pushed into the winding cylinder body, and FIG. 2 is a development view of the winding cylinder storage box of FIG. Fig. 4 is a top view of a state in which the winding cylinder is put into the winding cylinder storage box and the film is pulled out, and Fig. 4 is a side view showing the positional relationship among the support member, the push-in window, and the inner winding cylinder. FIG. 5 is a diagram showing an example of a practical support member shape.

  In FIG. 1 which shows an example of the wound cylinder storage box of the present invention, the storage box is a rectangular parallelepiped box, and has a storage chamber 12 whose upper surface is open and a lid 13 which can close the upper surface. . As shown in FIG. 2, the storage chamber 12 is connected to the front plate 1, the bottom plate 2, the rear plate 3, the side plates 8 connected to both ends in the longitudinal direction of the bottom plate 2, and both ends of the rear plate 3. Each surface is constituted by the auxiliary side plate 9 and the auxiliary side plate 9 ′ connected to both ends of the front plate 1. The lid 13 is openable and closable from the upper edge of the rear plate 3 of the storage chamber 12 and is connected in a direction covering the storage chamber 12, and extends from the front edge of the lid plate 4 to cover the front plate 1. Each surface is composed of the lid cover piece 5, the lid cover side plates 10 connected to both ends of the cover plate 4, and the lid cover auxiliary side plates 11 connected to both ends of the cover cover 5. An opening piece 6 is connected to the distal end edge of the lid cover piece 5. Further, a folded edge piece 7 is connected to the upper end edge of the front plate 1. In addition, the edge piece 7 may not be provided at the upper end edge of the front plate 1 or may be bent by 180 ° and bonded to the back surface of the front plate 1.

  In the auxiliary side plate 9 constituting the storage chamber 12, a support member 14 'that can be inserted into the core R1 of the winding cylinder R and supports the winding cylinder R is formed by the cut line i and the folding line g. Has been. The side plate 8 is provided with a window 14 that can be pushed into the storage chamber 12 through the folding line h and into which the support member 14 ′ is inserted into the winding cylinder R. The window 14 is formed by a fold line h and a cut line j. When the storage chamber 12 is assembled, the auxiliary side plate 9 is overlaid on the inner side of the side plate 8, and the support member 14 ′ is positioned on the inner side of the window 14.

  As shown in FIG. 1, a cutting tool K for cutting the film F is provided in the wound tube storage box of the present invention, and a necessary amount of film is drawn from the wound tube R stored in the storage chamber 12 and cut. Used. The shape of the cutting tool K is not particularly limited as long as it is a conventionally known material such as a straight shape, a V shape, an arch shape, etc., and the material is metal, plastic, vulcanized fiber, or the like. Moreover, the site | part where the cutting tool K is arrange | positioned may be any of the front-end edge part of the lid cover piece 5, the upper end edge part of the front board 1, and the ridgeline part between the bottom board 2 and the front board 1.

  In the wound cylinder storage box of the present invention, as shown in FIG. 4, the fold line g of the support member 14 ′ formed at the center of the auxiliary side plate 9 is inclined. The folding line g has a structure in which the end on the front plate 1 side is the upper end and the end on the rear plate 3 side is the lower end when assembled in the storage box, and the inclination is an angle formed with a straight line parallel to the bottom side of the bottom plate 2. θ is in the range of 4 ° to 12 °. When the support member 14 ′ in this range is inserted into the winding cylinder R, the support member has no inclination to prevent the winding cylinder R from popping out of the box when the consumer pulls out the film. Compared with the support member, the force required for the consumer to take out the winding cylinder R from the storage chamber 12 for some reason is the same as that of the support member having no fold line inclination. . This is because the performance of preventing the winding cylinder R from popping out particularly depends greatly on the inclination of the fold line g portion of the support member 14 '. When θ is in the range of 4 ° or more and 12 ° or less, the support member 14 ′ can exhibit sufficient pop-out prevention performance while maintaining the ease of taking out the wound tubular body R.

  In the wound tube storage box of the present invention, the winding tube R is rotated when the film is pulled out by providing the folding line g of the support member 14 ′ with a slope that decreases from the front plate 1 side to the rear plate 3 side. When the resistance is applied to 14 ′, the bottom plate and the horizontal fold line are not provided with respect to the direction of the force that the support member 14 ′ receives from the winding cylinder R, that is, the upward direction, the forward direction, and the diagonally forward direction. The durability of the support member 14 ′ is higher than that of the support member, and the effect of preventing the protrusion is greater. If the inclination angle θ is smaller than 4 °, the inclination angle θ formed with respect to the magnitude and direction of the force received from the winding cylinder R is not sufficient, so that the winding cylinder is expected between the support member and no inclination. The difference in the pop-out prevention effect of R does not appear. When θ is greater than 12 °, the angle formed is large, and the effect of preventing the winding cylinder R from popping out becomes very large. On the other hand, when the consumer takes out the winding cylinder R from the storage chamber 12 for some reason. There is a problem that it becomes extremely difficult to take out. From the standpoint of expressing the pop-out prevention effect and the ease of taking out in a well-balanced manner, it is more preferable to set the inclination angle θ in the range of 6 ° to 8 °.

  In the wound tube storage box of the present invention, the relationship between the maximum lateral width L of the support member 14 ′ and the inner diameter D of the core R1 is preferably 0.5 ≦ L / D ≦ 0.7 (1 formula). When L / D <0.5, the gap between the core body R1 and the support member 14 'is large, and when the consumer pulls out the film, the winding cylinder R moves until the support member 14' and the inner surface of the core body R1 come into contact with each other. Increasing the distance increases the momentum in the direction of jumping out, making it easier to jump out. Further, when L / D> 0.7, the maximum width L of the support member 14 ′ is larger than the inner diameter D of the core body R 1, so that the winding cylinder R is difficult to jump out, but it is difficult to pull out the film. The winding cylinder R tends to be difficult to take out.

  In the wound tube storage box of the present invention, the relationship between the fold line horizontal width S of the support member 14 ′ and the inner diameter D of the core R 1 is 0.4 ≦ S / D ≦ 0.64 (2 formulas). preferable. The displacement of the fold line horizontal width S has a great influence on the pop-out and take-out performance of the support member 14 ′ in the same manner as the maximum horizontal width L described above. In the case of S / D <0.4, the winding cylinder R is easy to take out, but the pop-out prevention performance tends to deteriorate. In the case of S / D> 0.64, the performance of preventing the winding tube R from popping out is sufficiently exhibited, but the ease of taking out tends to be hindered. For this reason, it is preferable that the balance between the pop-out prevention performance and the ease of taking out is in the range of the two formulas.

In the wound tube storage box of the present invention, the relationship between the maximum vertical width H orthogonal to the maximum horizontal width L of the support member 14 ′ and the inner diameter D of the core R 1 is 0.4 ≦ H / D ≦ 0.7 (3 formulas) ) Is preferable. When H / D <0.4, the degree of catching between the support member 14 'and the inside of the core R1 is insufficient, and the pop-out prevention performance tends to be insufficient. Further, H / D> 0.7 core R1 inside the support member 14 'is applied load until it is completely extracted longer the distance the contact time during extraction due to the long length of the supporting members 14' in the case of It tends to make the consumer feel unwieldy because of the longer period.

  With respect to the installation position of the folding line g of the support member 14 ′, that is, the installation height, in the wound tube storage box of the present invention, the end of the support member 14 ′ and the core body when the support member 14 ′ is pushed in It is preferable that the end of R1 is not in contact and is in a range where the pushing into the core R1 space is smooth. Further, when the winding cylinder R is stored in the storage chamber 12, if the fold line g exists in the upper semicircular region of the core R1, the end portion of the support member 14 'that contacts the core R1 when the film is pulled out This is preferable in that the distance between the fold line g and the fold line g is shortened, and the moment of the force that causes the entire support member 14 'to be folded upward about the fold line g is small, making it difficult to be folded.

  In the wound tube storage box of the present invention, the support member 14 'is installed in the front-rear direction in the same manner as in the up-down direction when the support member 14' is pushed in and the end of the core body R1. Are preferably not in contact with each other. Further, when the film or the like that is the winding body of the winding cylinder R is not used, when the winding cylinder R comes into contact with the inner surface of the front plate 1 or the rear plate 3 of the storage chamber 12, the support member 14 'and the core body R1. It is preferred that the inner surfaces do not contact. Further, when the outer diameter of the winding cylinder R is reduced as a result of consumption of the wrap film or aluminum foil of the winding cylinder R, the winding cylinder is contrary to the case where the outer diameter is large when not in use. It is preferable that the inner surface of the core body R1 and the support member 14 'be in contact with each other so that the body R does not contact the inner surface of the front plate 1 or the rear plate 3. In the initial stage of use of the wrap film, the contact between the winding cylinder R and the inner surface of the front plate 1 or the rear plate 3 of the storage chamber 12 has a smaller resistance than the contact with the support member 14 ', and the drawing is smooth. This is because, when touched, the drawer becomes heavy and the comfort of the consumer is lowered. Further, at the end of the use of the wrap film, the rolling friction resistance and the sliding friction resistance generated by the contact between the inner surface of the front plate 1 or the rear plate 3 and the winding cylinder R are reduced by the decrease in the weight of the winding cylinder R. The winding cylinder R will be moved around, reducing the comfort of the consumer. When the inner surface of the winding cylinder R and the support member 14 ′ are in contact with each other, the wrap film or the like of the winding cylinder R can be drawn smoothly. As long as the above-described conditions are satisfied, the shape of the support member 14 ′ is an arbitrary shape such as a combination of curves, a semicircular shape, a trapezoidal shape, an arrow shape, a saddle shape, or the like as shown in FIGS. It doesn't matter.

  In the wound container storage box of the present invention, the relationship between the maximum height H1 of the window 14, the width Wb of the rear plate 3, and the width Wc of the core R1 is preferably (Wb−Wc) ≦ H1 ≦ 2 (Wb−Wc). . This shows the relationship between the gap in the width direction and the maximum height H1 of the window 14 shown in FIG. 4 when the winding cylinder R is stored in the storage chamber 12, as shown in FIG. In the case where H1 is in this range, the appearance of the storage box and the ease of taking out the winding cylinder R are harmonized.

  When H1 <(Wb−Wc) in the wound cylinder storage box of the present invention, the window 14 is not caught inside the core body R1 when the wound cylinder R is removed from the storage chamber 12, so that the winding cylinder R is removed. Although it does not impede ease, it is difficult to push the window 14 cleanly with a pin or the like during production because the H1 is small, and the window 14 itself is torn or torn around the window of the side plate 8 and stored. The box appearance can be significantly degraded. In addition, when H1> 2 (Wb-Wc), there is no problem in pushing even if the window 14 is pushed in with a pin or the like during production, but there is a problem in appearance because the hole is large, and since H1 is large, the winding cylinder R is When taking out, window 14 itself may be caught inside core R1, and the ease of taking out winding cylinder R may be inhibited. As shown in FIG. 4, the maximum width L1 of the window 14 and the position and shape of the window 14 are large enough that L1 is not deteriorated in appearance when pushed with a pin or the like during production. The length of the window 14 may be small enough to fit within the range of the support member 14 'when assembled. As for the arrangement position, as shown in FIG. 4, when the storage box is assembled, the length from the end of the bottom plate 2 to the fold line h of the window 14 and the length from the end of the bottom plate 2 to the fold line g of the support member 14 '. Are preferably arranged so as to be substantially the same. The shape may be any shape as long as the above-described conditions are satisfied, but a rectangular shape is preferable. 1 and 2 show an example in which the fold line h of the window 14 is provided on the opening side of the storage chamber 12, the fold line h may be provided on the bottom plate 2 side. Further, a half-cut line g1 may be used instead of the fold line g of the support member 14 ', and a half-cut line h1 may be used instead of the fold line h of the window 14.

  The material used for the wound container storage box of the present invention is not particularly limited, such as paperboard, various corrugated cardboards, and plastics, but generally a paperboard having a thickness of 0.35 mm to 1.5 mm is used. The film wound around the core housed in the wound tube storage box of the present invention is not particularly limited, such as wrap film made of various resins, aluminum foil, cooking paper, etc., but polyvinyl chloride, polyvinylidene chloride, polyethylene A wrap film such as is particularly preferred.

Next, the evaluation method and scale used in the present invention are shown below.
<< Push-out prevention >> In the storage box as shown in FIG. 1, a cylindrical body R in which a vinylidene chloride film (trade name: Saran Wrap, manufactured by Asahi Kasei Home Products Co., Ltd.) is wound 50m is stored in the core R1. The support member 14 ′ provided on the auxiliary side plate 9 was pushed into the inside of the winding cylinder R through the window 14 provided in the above. 10 winding cylinder storage boxes each having the shape of the support member 14 'as shown in Table 1 or Table 2 are prepared, and the film is used up for drawing about 30 cm of film at a time. It was repeatedly verified whether or not the winding cylinder R jumped out from the storage box (drawing speed was approximately 36 m / min). ◎ (excellent anti-jumping performance) when it did not pop out even once ○ ○ when there are 3 or less boxes popping out of 10 boxes (practical) × 4 or more out of 10 boxes × ( No practicality).
<< Removability >> Prepare 10 cylindrical housing boxes similar to the evaluation of pop-out prevention, draw a digital force gauge on the core R1 end, draw an arc with the other cylindrical R end as a fulcrum Thus, when the operation of taking out the winding cylinder R from the storage box is performed, the removal force is less than 10N without damaging all the supporting members 14 'of the 10 boxes, and the winding cylinder can be easily made without feeling stress by the user. The case where the body R was taken out was marked as ◎ (excellent take-out property), and the case where the take-out force was 10 N or more and less than 15 N was ○ (with practicality), the support member 14 ′ was damaged or a large resistance was generated (the take-out force was 15N or more) was marked as x (impractical).

Hereinafter, although it demonstrates still in detail based on an Example, these do not limit the scope of the present invention.
The basic structure of the storage box provided for the embodiment (excluding the support member 14 'for preventing pop-out and the push-in window 14) is the same as that shown in FIG. 1, that is, the thickness is about 0.72 mm and the basis weight is about 550 g / m. Each of the front board 1, the bottom board 2, the rear board 3, the side board 8 and the auxiliary side boards 9, 9 'using ² coated cardboard (trade name: Suncoat (No. 11), manufactured by Oji Paperboard Co., Ltd.) Opening and closing from the upper end edge of the rear plate of the storage chamber 12 and the height of the upper opening formed by the surface is about 47 mm, the depth width Wa of the bottom plate is about 47 mm, the width Wb of the rear plate 3 is about 311 mm It is a rectangular parallelepiped box made up of a lid 13 formed on each side of the lid lid piece 5, the lid lid piece side plate 10, and the lid lid piece auxiliary side plate 11 that can be connected in the direction covering the storage chamber 12. Wrap fill from a wound cylindrical body (with a core width Wc of 307 mm and an inner diameter D of 30 mm) The required amount drawer, a wound cylinder storage box used in cutting.

  Based on this storage box, the shape of the support member 14 ′ for preventing popping out is a purse-type, and the size and the inclination angle θ of the fold line portion are changed as shown in Table 1 (experiment numbers 1 to 6). 20 boxes each were made by a machine and evaluated for pop-out prevention performance and take-out performance. The window 14 is formed so as to be a quadrangle as shown in FIG. 2 (the fulcrum is a half-cut line), and when the storage box is assembled, the entire window 14 is formed of the support member 14 ′ as shown in FIG. Arranged in a position overlapping within the area.

(Comparative example)
Under the same conditions as in the examples, the size of the support member 14 'for preventing popping out and the inclination angle θ of the fold line portion were changed as shown in Table 2 (experiment numbers 7 to 10) by machine with 20 boxes each. Each evaluation was carried out.

Table 3 shows the evaluation results and comprehensive evaluation results for each evaluation item.

  Each design shown in the examples within the scope of the present invention has a better balance between the pop-out prevention performance and the take-out property than the comparative example, and the folding line inclination angle θ is 6 ° ≦ θ ≦ 8 °, 0.5 ≦ L. /D≦0.7 (Formula 1) 0.4 ≦ S / D ≦ 0.64 (Formula 2) Experiment numbers 1 and 2 satisfying 0.4 ≦ H / D ≦ 0.7 (Formula 3) at the same time I know it ’s good. From these results, it can be seen that imparting an appropriate inclination to the support member 14 'greatly contributes only to the improvement of the pop-out prevention performance without impairing the take-out property.
