  FIG. 1 is a perspective view showing an example of a packaging container according to the present embodiment. The packaging container 100 according to the present embodiment has a rectangular main body bottom plate 11, a main body front plate 12 and a main body rear plate 13 erected on the long side of the main body bottom plate 11, and a short side of the main body bottom plate 11. A container body 10 having a main body left side plate 14 and a main body right side plate 15 and having a self-adhesive wrap film 1 containing a film roll 40 wound in a roll shape and having an open top surface; When the upper surface opening 16 of the container body 10 is closed, the upper surface plate 21 covers the upper surface opening 16 and is connected to the top surface plate 21 so as to be rotatable. A lid 20 having a lid front plate 22 arranged to be overlapped on the outside, and a lid that is fed from the film roll 40 and cuts the wrap film 1 drawn from between the main body front plate 12 and the lid front plate 22. Provided on the front plate 22 In the packaging container provided with the cutting means 30, the lid front plate 22 is provided with a lid embossed portion 70 raised from the surface of the lid front plate 22 to the main body front plate 12 side. A film holding unit 50 that holds the end of the wrap film on the side of the film roll 40 after cutting is provided in a region that contacts the lid embossing unit 70.

  A packaging container 100 shown in FIG. 1 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 at the upper end of the main body rear plate 13 so as to be rotatable, and can cover the upper surface opening 16 of the container main body 10. When the upper surface opening 16 is closed, the top plate 21 covers the upper surface opening 16, the lid front plate 22 is disposed so as to overlap the outside of the main body front plate 12, and the lid left side plate 24 and the lid right side plate 25 are respectively disposed on the left side of the main body. The face plate 14 and the main body right side face plate 15 are disposed so as to overlap each other. The area | region which contact | abuts with the lid | cover embossing part 70 among the main body front plates 12 is a flat surface, and the film holding | maintenance part 50 is provided.

  The cutting means 30 is attached to the back surface (the container body side surface) of the lid front plate 22 and is provided on the lower end side of the lid front plate 22. The material and shape of the cutting means 30 are not particularly limited, but are a saw blade-shaped cutting blade formed of cardboard, plastic, metal or the like. In the packaging container 100 shown in FIG. 1, the lower end side of the lid front plate 22 is the width direction of the packaging container 100 (hereinafter, the width direction of the packaging container 100 is the WW ′ direction in FIG. 1). The entire convex portion of the central portion is formed in a substantially V shape, and the cutting means 30 is also formed in a substantially V shape in accordance with this shape. In the present embodiment, the lid front plate 22 and the cutting means 30 as shown in FIG. 1 are not limited to a substantially V-shaped form. For example, the lower end side of the lid front plate 22 and the cutting means 30 can be formed in a linear shape or a substantially U shape.

  The material of the wrap film 1 is a resin or a resin composition having self-adhesiveness. The film roll 40 is formed by forming a wrap film 1 by molding a self-adhesive resin or resin composition into a single layer or a laminated sheet, and winding the wrap film 1 having a predetermined length into a roll. Examples of the resin include thermoplastic resins such as polyvinylidene chloride, polyvinyl chloride, polyethylene, polypropylene, polymethylpentene, polyester, and ethylene vinyl acetate copolymer. The resin composition is a mixture of a thermoplastic resin and a plasticizer. Examples of the plasticizer include aliphatic polybasic acid esters, aliphatic polyhydric alcohol esters, and oxyacid esters. In the present embodiment, the material of the wrap film is more preferably a material in which a plasticizer is blended with polyvinylidene chloride. In the present embodiment, the thickness of the wrap film is not particularly limited, but is generally 5 to 20 μm.

  The lid embossed portion 70 is a position where the user hits the thumb. As shown in FIG. 1, the lid embossed portion 70 is slightly depressed when the packaging container 100 is viewed from the lid front plate 12 side, so that the user can visually recognize the position where the thumb is applied. Can be detected. Further, the lid 20 can be easily opened and closed by placing a finger on the lid embossed portion.

  The shape of the lid embossed portion 70 is not particularly limited, and as shown in FIG. 1, in addition to a rectangular shape having a long side along the width direction of the packaging container 100, a shape such as a square shape, a circular shape, or a shape matched to the thumb is deformed. It is good also as an aspect. The bottom surface of the lid embossed portion 70 is preferably a flat surface in that the contact area with the film holding portion 50 provided on the main body front plate 12 can be increased.

  The film holding unit 50 is not particularly limited as long as the wrap film 1 can be held by pressing the wrap film 1 with the lid embossing unit 70. For example, the film holding unit 50 can apply an adhesive varnish or a smooth varnish. The film holding part can be formed by applying. Moreover, in the packaging container which concerns on this embodiment, it is more preferable that the outermost layer of the film holding part 50 is a self-adhesion film layer. By making the outermost layer of the film holding part a self-adhesive film layer, dust and dust accompanying the continuous use will not adhere and the film holding power will not decrease, and it will be a stable and sustainable film Holding power can be demonstrated.

  The self-adhesive film layer is a resin or resin composition having self-adhesiveness exemplified as the material of the wrap film 1 accommodated in the packaging container according to this embodiment. More preferably, it is the same material as the wrap film 1 accommodated in the packaging container. The thickness of the self-adhesive film layer can be selected from a wide range for the purpose of exerting the adhesion holding force to the wrap film, but it is economically preferable to use the wrap film 1 itself, and generally 5 to 20 μm. Is the thickness. Thus, since the wrap film 1 is very thin and has a high flexibility, it is extremely difficult to attach the wrap film 1 to the surface of the main body front plate 12 alone. Troubles such as turning over tend to occur. Therefore, it is difficult to form the film holding part 50 having a stable film holding force. The present applicant has found in Patent Document 2 that a film holding portion can be easily and stably formed by making a self-adhesive film a label structure including an adhesive layer and a base material layer.

  FIG. 2 is a laminated sectional view showing an example of the film holding unit. In the packaging container which concerns on this embodiment, the film holding | maintenance part 50 has the laminated structure of the adhesive layer 54, the base material layer 53, the adhesive bond layer 52, and the self-adhesion film layer 51 arrange | positioned in order from the container main body side. It is preferable. The total thickness of the laminated structure is preferably 40 to 350 μm. More preferably, it is 75-105 micrometers.

  As the pressure-sensitive adhesive (pressure-sensitive adhesive) constituting the pressure-sensitive adhesive layer 54, a pressure-sensitive adhesive generally used for label formation can be used. For such an adhesive, an adhesive in which a viscoelastic polymer such as rubber, polyurethane or acrylic resin is used as a main agent and an adhesive resin such as rosin or petroleum resin is blended with the main agent is widely used. The thickness of the pressure-sensitive adhesive layer 54 is, for example, about 10 to 100 μm. In the present embodiment, the material and thickness of the pressure-sensitive adhesive layer 54 are not limited.

  The base material layer 53 controls the rigidity of the film holding unit 50. The base material layer 53 is made of paper or a plastic film that is generally used as a label base material, and a material having higher rigidity than the self-adhesive film can be used. The thickness of the base material layer 53 is, for example, about 25 to 200 μm. In the present embodiment, the material and thickness of the base material layer 53 are not limited.

  The adhesive that constitutes the adhesive layer 52 is, for example, a solvent-type adhesive in which a main agent such as an acrylic resin, vinyl acetate, epoxy, or synthetic rubber is dissolved in an organic solvent such as ethyl acetate or acetone, or a non-solvent Type adhesive or aqueous emulsion type adhesive. Among them, a water-based emulsion type adhesive or a solventless type adhesive mainly composed of an ultraviolet curable acrylic resin, which is excellent in productivity and does not require treatment of a waste solvent, is preferably used. The thickness of the adhesive layer 52 is suitably about 5 to 50 μm. In the present embodiment, the material and thickness of the adhesive layer 52 are not limited.

  Furthermore, it is preferable to provide a print layer 56 such as a detection mark indicating the film holding unit 50 on the upper surface of the base material layer 53.

  The shape of the film holding unit 50 is not particularly limited, and may be a modified form such as a square or a circle in addition to a rectangle having a long side along the width direction of the packaging container 100 as shown in FIG.

  FIG. 3 is a diagram for explaining the positional relationship between the lid embossing portion and the film holding portion. The film holding unit 50 is provided in a region of the main body front plate 12 that is in contact with the lid embossing unit 70. As a form example provided in the contact area, for example, as shown in FIG. 3A1, the lid embossed portion 70 and the film holding portion 50 are arranged in the height direction of the packaging container 100 (hereinafter, the height of the packaging container 100). The direction corresponds to the HH ′ direction in FIG. 1), and as shown in FIG. 3 (b 1), the lid embossed portion 70 and the film holding portion 50 are the height of the packaging container 100. It is a form shifted up and down in the direction.

  About the form with which the height direction of the packaging container 100 shown to FIG. 3 (a1) corresponds, the example in a front view is further shown to FIG. 3 (a2) and FIG. 3 (a3). FIG. 3A2 shows a state in which the lid embossed portion 70 and the film holding portion 50 coincide with each other in the width direction of the packaging container 100 and are completely overlapped. 3A3 is a form in which the film holding unit 50 is shifted to the left in the width direction of the packaging container 100 with respect to the lid embossing unit 70. FIG. As shown in FIG. 3 (a1), the height direction of the packaging container 100 is the same in both the AA fractured sectional view of FIG. 3 (a2) and the BB fractured sectional view of FIG. 3 (a3). . In addition, in FIG. 3A3, the film holding part 50 showed the form which shifted | deviated to the left direction with respect to the lid | cover embossing part 70, However, the film holding | maintenance part 50 shifted | deviated rightward with respect to the lid | cover embossing part 70. It is good also as a form.

  About the form which the height direction of the packaging container 100 shown in FIG.3 (b1) has shifted | deviated up and down, the example in a front view is further shown in FIG.3 (b2) and FIG.3 (b3). FIG. 3B2 shows a form in which the lid embossing portion 70 and the film holding portion 50 are coincident in the width direction of the packaging container 100. FIG. 3 (b 3) shows a form in which the film holding unit 50 is shifted to the left in the width direction of the packaging container 100 with respect to the lid embossing unit 70. As shown in FIG. 3 (b1), the height direction of the packaging container 100 is shifted up and down in both FIG. 3 (b2) CC fractured sectional view and FIG. 3 (b3) DD fractured sectional view. In FIG. 3 (b 3), the film holding unit 50 is shown to be shifted to the left with respect to the lid embossing part 70, but the film holding part 50 is shifted to the right with respect to the lid embossing part 70. It is good also as a form. 3 (b2) and 3 (b3), the film holding part 50 is shown as being displaced upward with respect to the lid embossing part 70. The film holding unit 50 may be shifted downward with respect to the lid embossing unit 70.

  The region where the lid embossed portion 70 and the film holding portion 50 abut is preferably 20% or more with respect to the area of the bottom surface of the lid embossed portion 70. More preferably, it is 50% or more, and particularly preferably 100%. If it is less than 20%, the effect of efficiently adhering the film end to the film holding part 50 may not be obtained.

  As shown in FIG. 1, the position where the lid embossing part 70 and the film holding part 50 are provided is preferably provided in the center part in the width direction of the packaging container 100 in the main body front plate 12. Moreover, in the packaging container 100 of FIG. 1, although the cover embossing part 70 and the film holding | maintenance part 50 are provided one each, you may provide two or more.

  1 and 3, the lid embossed portion 70 and the film holding portion 50 have the same shape and the same dimensions, but can be modified as long as the effects of the present invention are not impaired. For example, a mode in which the film holding unit 50 is made smaller than the lid embossing unit 70, a mode in which the film holding unit 50 is made larger than the lid embossing unit 70, and a mode in which the shapes of the film holding unit 50 and the lid embossing unit 70 are made different. It is.

  FIG. 4 is a diagram illustrating a lid embossed portion provided with a non-slip protrusion. In the packaging container according to the present embodiment, it is preferable that at least one anti-slip protrusion 80 raised on the side opposite to the main body front plate 12 is provided on the bottom surface of the lid embossed portion 70. For example, even if the hand is slippery due to water or the like, it is possible to prevent the finger from slipping and more reliably press the film end against the film holding unit 50. Further, it becomes easier to confirm the position that the user should hold with the thumb by visual and tactile senses.

  FIG. 4A1 is a front view showing a configuration in which eight anti-slip protrusions 80 are provided on the bottom surface of the lid embossed portion 70 in four rows and two rows. FIG. 4 (a2) is a EE fracture cross-sectional view of FIG. 4 (a1). As shown in FIG. 4 (a2), the anti-slip protrusion 80 protrudes on the side opposite to the main body front plate 12, and is slightly convex when the packaging container is viewed from the front.

  The anti-slip protrusion 80 can be provided in the vicinity of the lid embossing portion 70 in the lid front plate 22 in addition to the bottom surface of the lid embossing portion 70. FIG. 4B1 shows a configuration in which eight anti-slip projections 80 are provided on the bottom surface of the lid embossed portion 70 in four rows and two rows, and further, eight in four rows and two rows are also provided in the vicinity of the lid embossed portion 70. FIG. FIG. 4B2 is a FF fracture cross-sectional view of FIG. 4B1. In this embodiment, the arrangement of the anti-slip protrusions 80 and the interval between the adjacent anti-slip protrusions 80 can be selected as appropriate according to the conditions such as the shape and area of the lid embossed portion 70 and the design of the packaging container. It is.

  When the anti-slip protrusion 80 is provided in the region of the lid embossed portion 70 that contacts the film holding portion 50, the film holding portion 50 can be easily confirmed visually and by touch, and the operator can place a thumb on the anti-slip protrusion 80. The contact is preferable in that the film end can be more reliably pressed against the film holding unit 50. However, the total area of the anti-slip protrusions 80 is preferably 40% or less with respect to the area of the region where the lid embossing portion 70 and the film holding portion 50 abut. More preferably, it is 20% or less, and particularly preferably 15% or less. If it exceeds 40%, the contact area between the lid embossing part 70 and the film holding part 50 may be reduced, and the force for bringing the film into close contact with the film holding part 50 may be weakened.

  In FIG. 4, the shape of the anti-slip protrusion 80 is circular, but it can be modified as long as the effect of the present invention is not impaired. For example, a triangle or a rectangle.

  The packaging container 100 has a horizontally long rectangular parallelepiped shape as shown in FIG. 1 and is generally obtained by a punching process and a punching process in which a flat plate material is punched to cut out a development view and form a crease line. It is formed through a box making process in which a blank sheet is bent to form a box. Therefore, the lid embossed portion 70 can be formed by pressing (embossing) using a pressing die simultaneously with the punching process, or can be formed by providing an embossing process before and after the punching process. it can. The depth of the lid embossed portion 70 is preferably 0.05 to 0.40 mm. More preferably, it is 0.10-0.30 mm. If it is less than 0.05 mm, the effect of providing the lid embossed portion 70 may not be obtained. If it exceeds 0.40 mm, the step between the lid front plate 22 and the lid embossed portion 70 is too large, and the main body front plate 12 or the lid embossed portion 70 may be deformed when the upper surface opening 16 of the container body 10 is closed. is there. In addition, the substrate may not be able to follow the elongation during embossing, and the substrate may be broken or cut.

  Formation of the film holding | maintenance part 50 can be performed with respect to the planar board | plate material or blank sheet before and behind a punching process. The present embodiment is not limited to the method for forming the film holding unit 50. For example, in the case where the outermost layer of the film holding unit 50 is an adhesive layer, an adhesive is applied to a region that is scheduled to come into contact with the lid embossed portion 70 in a planar plate material or blank sheet before and after the punching process. Thus, the film holding unit 50 can be formed. When the film holding unit 50 is formed as a laminate as shown in FIG. 2, the film holding unit 50 has a separator (not shown) on the surface opposite to the surface on which the base material layer 53 of the adhesive layer 54 is provided. ) Can be continuously pasted using a known label pasting apparatus that can be pasted while peeling the separator from the film holding portion forming label structure. By forming in this way, the film holding part 50 can be formed easily and stably. The separator is generally made of a paper or plastic film having a greater rigidity (ie, stiffer) and a larger thickness than the base material layer 53. By applying a release agent such as a silicone resin to the interface with the pressure-sensitive adhesive layer 54 as needed, a material having releasability is preferably used. However, as long as it is easy to peel from the pressure-sensitive adhesive layer 54, The setting of the rigidity and thickness is basically arbitrary.

  The anti-slip protrusion 80 can be formed by embossing at the same time as the punching process or before and after the punching process, similarly to the lid embossed portion 70. The diameter of the anti-slip protrusion 80 is preferably 1.0 to 5.0 mm. More preferably, it is 1.5-3.0 mm. The protrusion amount of the non-slip protrusion 80 is preferably 0.05 to 0.40 mm. More preferably, it is 0.10-0.30 mm. If it is less than 0.05 mm, the effect of providing the anti-slip protrusion 80 may not be obtained. If it exceeds 0.40 mm, the substrate may not be able to follow the elongation at the time of embossing, and the substrate may be broken or cut.

  Next, the relationship between the lid embossing part 70 and the film holding part 50 of the packaging container according to this embodiment will be described. FIG. 5 is a broken cross-sectional view through the lid embossed portion with the lid of the packaging container according to the present embodiment closed. As shown in FIG. 5, the wrap film 1 drawn from the film roll 40 in the container body 10 is guided to the outside of the packaging container 100 from the upper surface opening 16 through the space between the main body front plate 12 and the lid front plate 22. It is burned. The user first pulls out the wrap film 1 having a desired length and spreads it in a substantially horizontal state on a packaged object such as food or tableware. Then, the packaging container 100 is grasped with one hand, and the thumb is applied to the lid embossed portion 70 and pressed in the direction of the main body front plate 12. With the other hand, the wrap film 1 is pulled in the β direction, and the container is twisted in the α direction with the hand holding the packaging container 100. By this operation, the wrap film 1 is cut by the cutting means 30. The packaged object is packaged with the cut wrap film 1.

  In the present embodiment, the lid embossed portion 70 protrudes toward the main body front plate 12 side, and the film holding portion 50 has a region that comes into contact with the lid embossed portion 70. Therefore, when the lid embossed portion 70 is lightly pressed with a finger, The film 1 is sandwiched and fixed between the lid embossed portion 70 and the film holding portion 50, and the wrap film 1 can be cut at a predetermined length. After cutting, since the film end on the film roll 40 side is held by the film holding unit 50, the film can be prevented from unwinding stably and more reliably. Further, the user can easily confirm the depression of the lid embossing portion 70 visually and tactilely, and can reliably bring the wrap film 1 into contact with the film holding portion 50.

  FIG. 6 is a perspective view showing another example of the packaging container according to the present embodiment. In the packaging container 101 according to the present embodiment, at least a region extending in the direction (Y direction) intersecting the axial direction (X direction) of the film roll 40 in the region of the lid front plate 22 that does not contact the film holding unit 50. It is preferable that one rib portion 90 is provided.

  When cutting the wrap film, the lid front plate 22 is deformed by being pulled in the direction of pulling the wrap film 1 (β direction in FIG. 5) as shown by a two-dot chain line in FIG. 5. As a result of repeating the cutting, if the deformation of the lid front plate 22 does not return to the original state, it may be difficult to cut the wrap film 1. Therefore, deformation can be suppressed by providing the rib portion 90 and reinforcing the lid front plate 22.

  The rib portion 90 extends in the direction (Y direction) intersecting the axial direction (X direction) of the film roll 40 on the cover front plate 22. When the angle formed by the X direction and the Y direction is θ, θ is preferably 15 to 165 °. More preferably, θ is 45 to 135 °. Particularly preferably, θ is 65 to 115 °. In FIG. 6, all the θs are 90 °, but the rib portion 90 is a straight line C (hereinafter referred to as a center line) C passing through the center in the axial direction X of the roll 40 on the lid front plate 22. In each of the left and right regions of the lid front plate 22 to be divided, it is preferable to change θ so as to be line symmetric with respect to the center line C. Specifically, for example, in the region on the left side of the center line C (the W direction side in FIG. 6), θ is set to 115 ° for any rib portion, and the right side of the center line C (the W ′ direction in FIG. 6). In the region of (side), θ is set to 65 ° for any rib portion.

  In the present embodiment, the length of at least one rib 90 is 50 to 100% with respect to the length of the lid front plate 22 in the direction orthogonal to the axial direction (X direction) of the film roll 40. preferable. More preferably, it is 70 to 100%. Most preferably, it is 90 to 100%. By setting it as this range, the effect which provides the rib part 90 which reinforces the lid | cover front plate 22 can fully be exhibited. Here, the length of the rib portion 90 is a distance represented by asin θ, where a is a linear distance from the lower end s to the upper end t of the rib portion 90. For example, as shown in FIG. 6, when θ is 90 °, the length of the rib portion 90 is a (asin 90 ° = a). When θ is 60 °, the length of the rib portion 90 is √3a / 2 (asin60 ° = √3a / 2).

  By providing the rib portion 90, the lid front plate 22 can be reinforced, but the rib portion 90 is in the width direction (WW ′ direction in FIG. 6) of the packaging container 101 with the lid embossed portion 70 as the center. It is preferable to provide in the region P expanded by 2 cm. More preferably, it is provided in a region expanded by 1 cm. Furthermore, it is preferable that one rib portion 90 is provided on either side of the lid embossed portion 70, and more preferably, one rib portion 90 is provided on both sides of the lid embossed portion 70. FIG. 6 shows a form in which one rib portion 90 is provided on each side of the lid embossed portion 70 in the region P. Since stress concentrates on the lid embossed portion 70, the lid front plate 22 in the vicinity of the lid embossed portion 70 is particularly easily deformed. Can be suppressed. In the present embodiment, the number of rib portions 90 is not limited. Further, when a plurality of rib portions 90 are provided, the interval between the adjacent rib portions 90 is not limited.

  FIG. 7 is a partially enlarged sectional view of the rib portion, (a) is a sectional view taken along the line GG in FIG. 6, and (b), (c) and (d) are broken sectional views of a modification. As shown in FIG. 7A, in the packaging container 101 of FIG. 6, the rib portion 90 protrudes on the opposite side of the main body front plate 12 and is formed by embossing a plate material forming the packaging container 101. The rib portion 90 is not limited to this as long as the lid front plate 22 can be reinforced. As shown in FIG. 7B, the rib portion 90 can be formed to protrude toward the main body front plate 12 side. . In addition, as shown in FIGS. 7A and 7B, the rib portion 90 can be formed by embossing a plate material forming the packaging container 101, and the structure can be simplified. Although it is more preferable in terms of cost, it is not limited to this as long as the lid front plate 22 can be reinforced. For example, as shown in FIGS. 7C and 7D, the rib portion 91 can be a separate member. The material of the separate member is, for example, paper or plastic. Further, as shown in FIG. 7C, the rib portion 91 has a square cross-sectional shape, as shown in FIG. 7D, the rib portion 91 has a cross-sectional shape, or another cross-sectional shape. Whether or not. As another form of the rib part 90, the board | plate material which forms a packaging container is a form which gave the fold (fold) or the wave | undulation to the step shape. In the other embodiment, the rib portion 90 is a fold line or a ridge line of a wave. The difference between the apex of the convex portion of the rib portion 90 and the bottom surface of the lid embossed portion 70 is preferably 0.10 to 0.80 mm. More preferably, it is 0.20-0.60 mm. If it is less than 0.10 mm, the effect of providing the rib portion 90 may not be obtained. If it exceeds 0.80 mm, the lid 20 may be opened and closed. Further, when embossing is performed, the base material may not be able to follow the elongation and may be broken or cut.

  According to the present invention, the packaging container according to the present invention stably prevents the film end from being rewound into the packaging container after the wrap film having self-adhesiveness is drawn to a predetermined length and cut. Therefore, for example, it is suitable as a wrap film used as a packaging container for foods, containers and the like, and a wrap film packaging container used as a packaging material for preventing collapse of goods.
