Description

  The present invention relates to a packaging container for performing packaging while pulling out a long article wound in a roll shape from the container and cutting the sheet, and particularly relates to a packaging container partially provided with a blade portion.

  A long object wound in a roll shape can be packaged by pulling out only a predetermined length from the container and cutting with a cutting means provided on the lid body with the container lid closed. Possible packaging containers are known. The cutting means is a cutting blade having a serrated blade portion, and the blade portion is usually provided over the entire width of the lower end side of the lid front plate.

  In consideration of the safety of the cutting means, a wrap film storage box in which blade portions are provided only at both end portions of the lower end side of the lid front plate has been proposed (see, for example, Patent Document 1). In addition, a carton-wrapped package that can be cut in the lateral direction without tearing the film diagonally by combining a film with lateral tearability and a blade provided only at both ends of the lower end of the lid front plate. Films have been proposed (see, for example, Patent Document 2).

  The shape of the cut end of the long object cut by the serrated blade portion is serrated. For this reason, there is a case where a so-called longitudinal tear occurs in which a long object is torn in the MD (Machine Direction) direction (also referred to as a longitudinal direction) starting from a sawtooth notch. When vertical tearing occurs in a long object remaining on the roll body side, the cut end is rewound into the container, and the operation of searching for and pulling out the cut end when used again becomes complicated. Moreover, when a longitudinal tear occurs in a long object separated from the roll body, appropriate packaging cannot be performed. The problem of vertical tearing can be improved by partially providing the blade portion on the lower end side of the lid front plate as in Patent Document 1 or 2. However, as in Patent Document 1, if the blades are provided only at both ends of the lower end side of the lid front plate, the cutting direction of the long object is not determined at the time of cutting. May be drawn into the container. Moreover, in patent document 2, the elongate thing which can be used is restricted to what has the characteristic which is easy to tear to a horizontal direction.

The blade 31 of the cutting means 30 is provided in a region including the apex of the convex shape in the lower end side 22b of the lid front plate 22, At least one of 10 or the lid 20 has auxiliary means 50 (51, 52, 54) for controlling the movement of the long object 1 when the long object 1 is cut.

  The long object 1 is, for example, a wrap film, an aluminum foil, or a paper sheet for cooking. The wrap film is, for example, a polyvinylidene chloride film, a polyvinyl chloride film, a polyethylene film, a polypropylene film, a polymethylpentene film, a polyester film, or an ethylene vinyl acetate copolymer film. Of these, a polyvinylidene chloride film is more preferable. Polyvinylidene chloride films are prone to longitudinal tearing but can prevent them. The wrap film includes a form containing various auxiliary agents such as a plasticizer and a stabilizer. The paper sheet for cooking is a sheet obtained by applying silicon resin processing or fluororesin processing to one or both sides of a paper base material. It does not matter whether the long object 1 is a single layer or a laminate. Although the thickness of the elongate object 1 is not specifically limited, In the case of a wrap film, generally it is 5-20 micrometers.

  The packaging container 100 is formed of a plate material such as cardboard or plastic. Although the thickness of a board | plate material is not specifically limited, Generally it is 0.45-0.70 mm. The container body 10 is a horizontally long shape having an upper surface opening 16 formed by a main body front plate 12, a main body rear surface plate 13, a main body left side plate 14, and a main body right side plate 15 which are erected on each side of a rectangular main body bottom plate 11. It is a substantially rectangular parallelepiped box. The lid 20 is integrally provided on the upper end side 13a of the main body rear plate 13 so as to be rotatable. When closed, the top plate 21 covers the top opening 16, and the lid front plate 22 is disposed so as to overlap the outside of the main body front plate 12. As shown in FIG. 1 or FIG. 2, the lower end side 22 b of the lid front plate 22 has a convex shape in which the central portion is positioned closer to the container body bottom plate 11 side than both ends. In FIG. 1 or 2, as an example, the convex shape is a V-shape formed by the lower end side 22 b of the lid front plate 22, but the present invention is not limited to this. The convex shape is, for example, a U shape or an arc shape in addition to the V shape. It is preferable that the convex apex is on a straight line C (hereinafter referred to as a center line) C passing through the center in the longitudinal direction (WW ′ direction in FIG. 1) of the lid front plate 22. Moreover, it is preferable to form the lower end side 22b of the lid front plate 22 in line symmetry with the center line C as an axis of symmetry. The lid 20 may include a lid left side plate 24 and a lid right side plate 25 that are respectively disposed outside the main body left side plate 14 or the main body right side plate 15 when closed.

  The cutting means 30 is a cutting blade having a blade portion 31. The material of the cutting means 30 is not particularly limited, and is, for example, cardboard, plastic, or metal. In the present embodiment, a slit is made at the center of the long object 1 by the blade portion 31, and the subsequent cutting is performed by tear propagation. As shown in FIG. 1 or FIG. 2, the blade portion 31 is preferably serrated. The blade part 31 is provided in the area | region containing the convex vertex among the lower end sides 22b of the lid | cover front board 22. FIG. The blade portion 31 is preferably formed in line symmetry with the center line C as an axis of symmetry. The width of the blade portion 31 is preferably 5 to 50 mm, and more preferably 10 to 30 mm. By setting it as this range, the cutting | disconnection by tear propagation after making a tear into the center part of the elongate object 1 with the blade part 31 can be performed more favorably. As shown in FIG. 1 or FIG. 2, the cutting means 30 is provided with a short cutting blade or has a length corresponding to the entire width of the lower end side 22b of the lid front plate 22, and the cutting portion is only at the center portion. You may install the provided cutting blade (not shown).

  The auxiliary means 50 includes (1) a presser plate 51 provided at least in the center in the longitudinal direction of the upper surface opening 16, (2) a slip prevention means 52, or (3) a blade portion of the lower end side 22 b of the lid front plate 22. It is preferable that it is at least 1 type of (1)-(3) of the level | step-difference part 54 provided in the main body front plate 12 which touches or is inserted in the lower end side in which 31 is not provided. Since these auxiliary means 50 do not require a significant design change compared to a conventional packaging container, an existing production line can be used. The auxiliary means 50 is a means for controlling the movement of the long object 1 when the long object 1 is cut. The auxiliary means 50 suppresses the movement of the long object 1 at the time of cutting from the working surface, and the long object at the time of cutting. 1 tear direction can be classified into an induction type that guides in a TD (Transverse Direction) direction (hereinafter sometimes referred to as a lateral direction). Both types have the effect of promoting the tear propagation in the lateral direction of the long object 1 and preventing vertical tearing. (1) The presser plate 51 belongs to the suppression type. (2) The slip prevention means 52 belongs to the suppression type. (3) The step portion 54 belongs to both the suppression type and the induction type.

  In FIG. 1 or FIG. 2, the form having all of (1) to (3) is shown as an example. However, the present invention is not limited to this, and the form having only (1), only (2), or only (3) Also good. Moreover, it is preferable that the packaging container 100 which concerns on this embodiment has 2 or more types of auxiliary means 50. FIG. By combining two or more types of auxiliary means 50, the stability in the cutting direction is improved as compared with the case of having only one type. The combination of the auxiliary means 50 is, for example, (1) + (2), (1) + (3), (2) + (3), (1) + (2) + (3). However, these are merely examples, and the present invention is not limited to these. Among these, (2) (1) + (2), (2) + (3), (1) + (2) + (3), which is a combination of the slip prevention means 52 and the other auxiliary means 51, 54 Is preferable because more stable cutting is possible.

  Next, each auxiliary means 50 (51, 52, 54) will be described.

(1) Presser plate FIG. 3 is a sectional view taken along line XX of FIG. The presser plate 51 is provided at least in the center of the upper surface opening 16 in the longitudinal direction (the WW ′ direction in FIG. 1). More preferably, as shown in FIG. 1 or FIG. 2, it is provided over the entire width of the upper surface opening 16 in the longitudinal direction (WW ′ direction in FIG. 1). By having the presser plate 51, the long object 1 is pulled out from between the main body front plate 12 and the lid front plate 22 via the presser plate 51 and the top plate 21 as shown in FIG. 3. . For this reason, since the path | route in the packaging container until the elongate object 1 is pulled out of a packaging container is extended compared with the case where the pressing board 51 is not provided, the elongate object 1 protrudes at the time of a cutting | disconnection. This makes it difficult to improve the stability in the cutting direction.

  In FIG. 1 or FIG. 2, the press plate 51 is connected to the upper end side 12 a of the main body front plate 12 as an example (see FIG. 3), but the present invention is not limited to this. For example, the pressing plate may be provided with a locking piece (not shown) connected to the end of the pressing plate, and the locking piece (not shown) may be locked to the main body front plate 12 and attached. Further, the holding plate 51 is a side other than the upper end side 12 a of the main body front plate 12 among the sides forming the upper surface opening 16, that is, the upper end side 13 a of the main body rear surface plate 13, the upper end side 14 a of the main body left side plate 14, or The main body right side surface plate 15 may be connected or locked to the upper end side 15a. As a more preferable mode, the presser plate 51 is connected or locked to at least two sides among the sides forming the upper surface opening 16. Since the movement of the presser plate 51 itself is fixed, the movement of the long object 1 at the time of cutting can be more reliably suppressed, and the stability in the cutting direction can be improved.

  FIG. 4 is a cross-sectional view of a packaging container having a holding plate of another form. 4 is a cross-sectional view of a position corresponding to XX in FIG. As shown in FIG. 4, the holding plate 510 has an insertion piece 511 that is connected to the upper end side 12 a of the main body front plate 12 and that is connected to a side opposite to the side to be connected. It is preferable that the rear plate 13 is inserted and locked inside. The presser plate 510 covers the upper surface opening 16, and the long object 1 passes through a slit-shaped hole s formed by cutting out the presser plate 510, passes between the presser plate 510 and the top plate 21, It is pulled out from between the face plate 12 and the lid front plate 22. Since the path in the packaging container until the long object 1 is pulled out of the packaging container is further extended, the long object 1 becomes more difficult to slide out during cutting, and the stability in the cutting direction can be further improved. it can. The shape of the slit-shaped hole s may be, for example, a rectangle having a constant width over the longitudinal direction of the upper surface opening 16 (the WW ′ direction in FIG. 1) or a deformed shape. The deformed shape is, for example, a form in which a wide portion is provided in the central portion of the upper surface opening 16 in the longitudinal direction (W-W ′ direction in FIG. 1).

  An anti-slip portion (not shown) that suppresses movement by being in close contact with or sticking to the long object 1 may be provided on a part or the entire surface of the presser plates 51 and 510. The anti-slip part is, for example, a label having a coating layer such as an adhesive and an anti-slip varnish, and an anti-slip layer comprising an adhesive and an anti-slip varnish as the outermost layer. Moreover, when the elongate object 1 is a polyvinylidene chloride film, the anti-slip | skid part may be a label which has a polyvinylidene chloride film layer as an outermost layer using the self-adhesive property which a polyvinylidene chloride film has.

(2) Anti-slip means The anti-slip means 52 adheres to or adheres to the long object 1 and suppresses movement. For example, an application layer such as an adhesive or anti-slip varnish, and an adhesive or anti-slip as the outermost layer. It is a label having an anti-slip layer made of varnish or the like. Further, when the long object 1 is a polyvinylidene chloride film, the slip prevention means 52 may be a label having a polyvinylidene chloride film layer as the outermost layer by utilizing the self-adhesiveness of the polyvinylidene chloride film. Good.

  The slip prevention means 52 is preferably provided in at least one of the upper portion of the main body front plate 12, the upper end side 12 a of the main body front plate 12, or a flap (not shown) installed on the main body front plate 12. By providing the anti-slip means 52 on at least one of these, the movement of the long object 1 is not interrupted when the long object 1 is cut, and the movement of the long object 1 is not obstructed when the long object 1 is pulled out. Can be cut more stably. The upper part of the main body front plate 12 is a region overlapping the lid front plate 22 on the surface of the main body front plate 12. A flap (not shown) installed on the main body front plate 12 is a portion that is connected to the main body front plate 12 and protrudes to the outside of the container main body 10. In FIG. 1 or FIG. 2, although the form provided in a part of upper part of the main body front board 12 was shown as an example, it is not limited to this. For example, the slip prevention means 52 is provided on the entire upper surface of the main body front plate 12, provided only on the upper end side 12 a of the main body front plate 12, provided only on a flap (not shown) installed on the main body front plate 12, or the main body You may provide in both the upper part of the front plate 12, and the upper end edge 12a. The region where the anti-slip means 52 is provided in the longitudinal direction (WW ′ direction in FIG. 1) of the main body front plate 12 is at least the central portion in the width direction (WW ′ direction in FIG. 1) of the long object 1. It is preferable that the region is in contact. More preferably, as shown in FIG. 1 or FIG. 2, the entire area in the width direction (the WW ′ direction in FIG. 1) of the long object 1 is in contact.

(3) Stepped portion The stepped portion 54 is provided at least in the central portion in the longitudinal direction (WW ′ direction in FIG. 1) of the main body front plate 12. More preferably, as shown in FIG. 1 or FIG. 2, the main body front plate 12 is provided over the entire width in the longitudinal direction (WW ′ direction in FIG. 1). The step portion 54 preferably has a notch portion 54b in a portion where the blade portion 31 is located when the lid 20 is closed.

  When the stepped portion 54 is in contact with the lower end side where the blade portion 31 is not provided in the lower end side 22b of the lid front plate 22, the stepped portion 54 is connected to the lid front plate 22 via a score line, and It is preferable to form it by cutting along a score line. In this embodiment, before opening the packaging container 100, the lid front plate 22 and the stepped portion 54 are integrated, and are arranged on the outside of the main body front plate 12. And when opening, it cut | disconnects along a cut line, and the lid | cover front plate 22 and the level | step-difference part 54 will isolate | separate, and will be in the state shown in FIG. When the long object 1 is pulled out and the lid 20 is closed as shown in FIG. 2, the long object 1 is separated from the upper end side 54 a of the stepped portion 54 and the lower end side 22 b of the lid front plate 22 as shown in FIG. 3. Is sandwiched between. For this reason, the movement of the long object 1 can be suppressed at the time of cutting, and the tearing direction of the long object 1 can be guided in the lateral direction to increase the stability in the cutting direction. As another form in the case where the stepped portion 54 is in contact with the lower end side 22 b of the lid front plate 22, the main body front plate 12 may be provided with an embossing projecting outward as the stepped portion 54.

  FIG. 5 is a cross-sectional view of a packaging container having a stepped portion of another form. FIG. 5 is a sectional view of a position corresponding to XX in FIG. In the case where the lower end side where the blade portion 31 is not provided is inserted in the lower end side 22b of the lid front plate 22, the stepped portion 540 is provided with a plate-like member fixed to the outside of the main body front plate 12, for example. preferable. Although the material of a plate-shaped member is not specifically limited, For example, it is a cardboard. As shown in FIG. 5, the stepped portion 540 extends upward from the lower end side where the blade portion 31 is not provided in the lower end side 22 b of the lid front plate 22 when the lid 20 is closed. It is preferable to further have. As shown in FIG. 5, the extending piece 541 may be formed by providing a ruled line 542 and bending it outward, or may be provided continuously without providing a ruled line. When the lid 20 is closed, the lid front plate 22 is inserted between the main body front plate 12 and the extension piece 541, so that the long object 1 is connected to the extension piece 541 and the lower end side 22 b of the lid front plate 22. Can be stably held between the two, and the movement of the long object 1 can be more reliably suppressed during cutting. Further, the tear direction of the long object 1 can be reliably guided in the lateral direction.

  The cutting method will be described with reference to the packaging container shown in FIG. First, the packaging container 100 is held with one hand, the long object 1 having a desired length is pulled out with the other hand, and the lid 20 is closed. While the hand holding the long object 1 is fixed, the blade 31 of the cutting means 30 provided in the central part of the packaging container 100 is applied to the drawn long object 1 and a slit is made in the central part of the long object 1 The long object 1 is sequentially cut from the center toward both ends by tear propagation. The position of the cut end 1a of the long object 1 remaining on the packaging container 100 side is that the resistance at the time of cutting can be reduced, so that the lid 20 is closed and the lower end side 22b of the cover front plate 22 is closed. It is preferable that it is on the main body bottom plate 11 side. Among these, with the lid 20 closed, the virtual line drawn on the main body front plate 12 through the convex apex of the lower end side 22b of the cover front plate 22 and parallel to the main body bottom plate 11 is used as a reference. When the line O is used, the position of the cut end 1a of the long object 1 remaining on the packaging container 100 side is more preferably on the reference line O.

  Next, although an example of the present invention is given and explained, the present invention is not limited to these examples.

  FIG. 6 is a perspective view showing a basic packaging container used for cutting performance evaluation. As the basic packaging container 900, the packaging container shown in FIG. 6 was prepared. The basic packaging container 900 is made of thick paper having a thickness of 0.7 mm, and has an outer shape of a substantially rectangular parallelepiped shape having a width w1 of 315 mm, a depth d1 of 44 mm, and a height h1 of 44 mm. The lower end side 22b of the lid front plate 22 is V-shaped, and the center line C is an axis of symmetry. The height difference t1 between the V-shaped apex and both ends was 10 mm. A cutting blade having a serrated blade portion 31 having a width w2 of 18 mm is attached to the center portion of the lower end side 22b of the lid front plate 22 as the cutting means 30. As the long object 1, a polyvinylidene chloride film having a thickness of 10 μm and a width w3 of 30 cm was used. The packaging container which attached the basic packaging container 900 to the 1 or 2 or more auxiliary means shown in Table 1 was set as Examples 1-7.

  Each auxiliary means used the following.

(1) The presser plate is a 313 mm × 20 mm rectangular cardboard (thickness 0.7 mm) arranged along the upper end side 12 a of the main body front plate 12 of the packaging container 900, and the upper end side 14 a of the main body left side plate 14. And it fixed to the upper end side 15a of the main body right side face plate 15.

(2) The slip prevention means was a rectangle of 310 mm × 20 mm, and a label (stopper label) having an antislip layer on the outermost layer was attached along the upper end side 12 a of the main body front plate 12 of the packaging container 900.

(3) The step portion was formed by connecting to the lid front plate 22 via a cut line and cutting along the cut line.

(Cutability evaluation)
About the basic packaging container 900 (comparative example 1) which has not attached the packaging container of Examples 1-7 and an auxiliary | assistant means, the cutting property evaluation of the elongate thing was performed by the method shown next. First, the packaging container was grasped with one hand, a long object was pulled out 30 cm with the other hand, and the lid was closed. While pulling the long object in the horizontal direction, twist the container inward with the hand holding the container. By this operation, a slit is made in the central portion of the long object by the blade portion of the cutting means. Further, the long object is pulled in the horizontal direction as it is, and the long object is sequentially cut from the center toward both ends by tear propagation. After cutting the long object, the lid was opened, and the maximum value of the displacement from the reference line O was recorded for the cut end of the long object remaining on the packaging container side. With respect to the amount of displacement, the value on the reference line O is 0, the amount of displacement on the main body bottom plate 11 side from the reference line O is indicated by +, and the amount on the upper surface opening 16 side is indicated by-. The cutting operation was performed 20 times, and the average value of the maximum value of the displacement amount at each time is shown in Table 1.

The evaluation criteria for cutting performance evaluation are as follows in descending order of evaluation. The higher the order of evaluation, the smaller the resistance during cutting.
1. The displacement is 0 mm (practical level).
2. The displacement amount exceeds 0 mm and is +10 mm or less (practical level).
3. The displacement is -10 mm or more and less than 0 mm (practical level).
4). The displacement amount exceeds +10 mm and is +20 mm or less (practical lower limit level).
5). Displacement exceeds +20 mm (practical unsuitable level).
6). The displacement is less than −10 mm (practical unsuitable level).

  From Table 1, when Examples 1-7 are compared with Comparative Example 1, it has at least any one of the auxiliary means (1) to (3), compared with the case where there is no auxiliary means. Thus, it was confirmed that the amount of displacement of the cut end with respect to the reference line O was small.
