JP6564391B2 - Packaging material sheet, packaging box for smoking products and method for producing packaging material sheet - Google Patents

Description

  The present invention relates to a packaging material sheet, a packaging box for smoking products, and a method for producing a packaging material sheet.

  The present invention is particularly applicable in the packaging industry and in particular in the manufacture of packaging boxes for smoking products (preferably tobacco etc.).

  In the prior art, it is common to wrap a cigarette packaging box in a sealed packaging. The packaging part generally consists of a cellophane sheet, and the user removes the packaging part when opening the packaging box for the first time.

  Usually, for easy removal, the sheet is provided with an opening tape that can be gripped by the user, making it easy to tear the material along a predetermined line defined by the band itself.

  In the most common solution known for many years, a cigarette packaging box extends in a circle and a circumferential opening tape whose lid is located in the opening line in front of the lid in a hinged packaging box Is used.

  Often, however, this solution has the disadvantage that it is limited to creating a separation line between the upper and lower parts of the sheath. The exterior is difficult to remove because it remains at least partially attached to the packaging box due to heat sealing.

  In order to eliminate these drawbacks, several solutions have been developed in recent years, and all these multiple solutions have an exterior that defines a triangular opening flap rather than along a single line. Based on a double bifurcated band that is split along two bifurcating lines.

  In particular, the patent document WO2013 / 189944 describes a solution for an opening tape comprising a further annular band after a conventional annular band extends over an initial peripheral stretch. This slanted band branches towards the lower half of the packaging box exterior, allowing the part of the exterior to tear.

  A similar solution is disclosed in the patent document WO2013 / 042593, and the cellophane exterior of the cigarette packaging box comprises two bands. The two bands diverge from each other, but both extend in an annular shape and are connected in a tear tab that can be gripped by the user.

  Disadvantageously, both of the above solutions do not guarantee that the upper part of the exterior is simply removed, is generally the most inconvenient for the user, and in many cases both solutions are More difficult to handle than conventional solutions.

  In particular, for the exterior shown in WO2013 / 042593, it is emphasized that this type of exterior complicates the process of fixing the band to the cellophane film.

  In fact, these steps are generally continuous and the rate at which the two bands are applied by the application of the two bands shaped as disclosed, following two separate processes. It will be very difficult to adjust. In particular, by fixing a linear band and a curved band having different contact speeds at the same time, the step of attaching the band becomes extremely complicated, and the operation failure rate increases considerably.

  A further prior art solution is disclosed in patent document WO2013 / 120899, wherein the opening means is defined by a V-shaped band that is horizontally oriented and extends at least partially around the packaging box. Yes. Although this solution enables the upper portion of the exterior to be torn, it is inconvenient and requires a significant improvement in the exterior device used.

(Disclosure of the Invention)
Accordingly, it is an object of the present invention to provide a packaging material sheet, a packaging box for smoking products, and a method for producing a packaging material sheet that overcomes the disadvantages of the prior art described above.

  More particularly, it is an object of the present invention to provide a packaging sheet that is simply made and formed so that it can be easily torn and opened.

  Another object of the present invention is to provide a pack for smoking products that can be opened quickly and easily.

  Still another object of the present invention is to provide a method for producing a packaging sheet that can be carried out efficiently and simply.

  These objectives include packaging sheets according to one or more of claims 1 to 12, packaging boxes for smoking products according to one or more of claims 13 to 16, and claims 14 to 14. This is accomplished by a method for making a packaging sheet as described in one or more of 18.

  More particularly, these purposes are that the sheet extends between the first edge and the second edge along the packaging direction and tears the sheath to remove the container in use. This is achieved by a packaging material sheet for making an outer packaging of a container, which is provided with an opening means that can be gripped by a user for opening.

According to one aspect of the present invention, the opening means is:
A first band extending along the packaging direction, dividing the sheet into a first part and a second part and defining a first opening line;
Defining a second opening line extending from the first edge away from the first band within the second portion of the sheet and inclined at an angle with respect to the first opening line; A second band to
A third band that hits the first band at at least one junction and extends at least partially within the first portion of the sheet, the third band from the junction, A third band defining a third tear line extending within the first portion of the sheet away from the tear line;
Is provided.

  Thus, advantageously, since the second and third bands define an opening line that extends from the first band and on the opposite side across the first band, generally first of the bands By acting on one, the user can easily tear and open both parts of the sheet.

  Thus, advantageously, the first opening line and the second opening line can be “activated” simultaneously by a simple pulling action by the user.

  Preferably, the second band is close to the first edge of the sheet, while the third band is close to the second edge of the sheet.

  Each of the first band and the second band extends from the first edge. In other words, the first band and the second band each have their origin at the first edge.

  Even more preferably, the first opening line and the second opening line extend away from the first edge and away from each other, like the first band and the second band, but the first Have their origin at separate points on one edge. Therefore, the first opening line and the second opening line do not hit each other.

  Preferably, the third band extends within the first portion of the sheet, begins with the first band, defines a meeting point, and extends away therefrom to define a third opening line. Having end segments. More precisely, the third band extends from the end segment and away from the second segment of the sheet.

  More particularly, the second band and the third band are both a first end segment near the first edge of the sheet and a second end remote from the first edge of the sheet. Extends between the segments.

  The first end segment of the second band and the second end segment of the third band define a first edge portion and a second edge portion of the sheet, respectively. Both the first edge portion and the second edge portion extend within the second portion of the sheet over a predetermined length from the first band.

  This is preferably achieved by a method for making a sheet that constitutes the subject of the invention and makes it possible to obtain three bands and three opening lines quickly and easily.

In fact, this method
-Providing a continuous film of packaging material (which can be heat sealed), a (reinforcing) tape, and a plurality of (reinforcing) bands;
-Unwinding the film along a predetermined unwinding direction;
-Stacking (and fixing) the tape parallel to the unwinding direction on the film so as to divide the film into a first part and a second part on opposite sides across the tape;
-Each band is overlaid on the film (and fixed apart) so that each band is spaced from the next band and has an intersection area with the tape, the intersection area being a sheet Disposed between at least one first stretch located in the first part of the sheet and at least one second stretch located in the second part of the sheet;
The film is cut in each band along a cutting line transverse to the unwinding direction (preferably perpendicularly), the band being cut into a first one-side part comprising a first stretch and a second Splitting into a second one-sided portion at least partially comprising a stretch and extending from the tape;
Is provided.

  Thus, the cutting step divides the film into two adjacent sheets, the first one-side portion of the band defining the third band of one sheet, while the second one-side portion is the other A second band of the sheet is defined. The tape defines a first band on both sheets.

  Thus, advantageously, in only two operations: the tape application step and the sequential band application step, the packaging box exterior is completely removed both in its upper part and in its storage part. It is possible to obtain three bands and three opening lines that allow opening.

  These and other features are described below in the following drawings with respect to preferred embodiments of the method for making packaging sheets, smoking product packaging boxes and packaging sheets as shown in the following drawings. It will be clearer from.

(Best Mode for Carrying Out the Invention)
Referring to the following drawings, reference numeral 1 denotes a packaging material sheet (more specifically, an exterior) for containers for smoking products.

  More particularly, this does not limit the scope of the present invention, but a container such as, for example, a cigarette packaging box 100 is specified herein.

  However, the sheet 1 according to the present invention may be used for packaging (more specifically, packaging) any type of container 102.

  The packaging material sheet 1 is preferably made of a heat-sealable material such as cellophane. In use, this material is preferably designed to wrap around the container 102 and seal it by heat sealing to form the sheath 101.

  In this regard, the sheet 1 is preferably made of a transparent material.

  The sheet 1 extends along the packaging direction “A” in the plane between the first edge 2 and the second edge 3.

  The packaging direction “A” defines the peripheral direction in which the sheet 1 is packaged around the container 101 during the packaging process.

  The first edge 2 and the second edge 3 are preferably parallel and opposed to each other.

  Preferably, the sheet 1 is substantially quadrilateral and has two longitudinal edges 4. The edge 4 is directed in a direction according to the packaging direction “A” and connects the first edge 2 and the second edge 3 to each other.

  Accordingly, the sheet 1 is defined by a first dimension “D1” defined by the distance between the first edge 2 and the second edge 3 and the distance between the two longitudinal edges. And has a second dimension “D2”.

  Obviously, the values of these dimensions depend on the size of the container 101 packaged by the sheet 1.

  Further, the sheet 1 is associated with an opening means 5. The unsealing means 5 can be gripped by the user to tear the sheet 1 (defining the sheath 101 in use) to take out the container 102.

The unsealing means 5 is tape-type, i.e. the unsealing means 5 is overlapped and secured to the sheet 1 itself (by gluing means or sealing) and a band of material (different from the material of the sheet 1) and the user And at least a tab 104 that can be gripped.

  In use, when the tab is pulled, the difference between the tear strength of the sheet and the tear strength of the band creates an opening line in the sheet 1 that extends along the band itself.

  According to one aspect of the invention, the opening means 5 comprises a first band 6. The first band 6 extends along the packaging direction “A” and defines a first opening line “L1” in the sheet 1.

  The first band 6 divides the sheet 1 into a first portion 1a and a second portion 1b.

  Preferably, the first band 6 extends between the first edge 2 and the second edge 3.

  Accordingly, the first band 6 extends over the entire length of the dimension “D1” of the seat 1.

  In other words, the first band 6 has a first end 6 a located at the first edge 2 and a second end 6 b located at the second edge 3.

  The unsealing means 5 includes a second band 7 extending so as to be separated from the first band 6 inside the second portion 1 b of the sheet 1.

  Accordingly, the first band 6 and the second band 7 are separated from each other.

  The second band 7 defines a second opening line “L2” that is inclined at an angle with respect to the first opening line “L1”.

  Preferably, the first band 6 and the second band 7 have at least one intersection point 8.

  Thus, advantageously, once the user pulls one tab, the two branching unsealing lines expand in the sheet 1.

  In use, the first opening line “L1” and the second opening line “L2” allow the second portion 1b of the sheet 1 to be easily removed from the container 101.

  More specifically, the second band 7 hits the first band 6 and is spaced from its first end segment 7a close to the first edge 2 of the seat 1 and away from the first band 6. And from its second edge 7b, which is remote from the first edge 2 of the sheet 1.

  Preferably, both the first band 6 and the second band 7 extend from the first edge 2. Accordingly, the first end segment 7 a is located at the first edge 2.

  More precisely, the first end segment 7 a of the second band 7 defines a portion 2 a of the first edge 2 of the sheet 1.

  Further, the intersection 8 is located near the first edge 2 of the sheet 1 (or at the first edge 2).

  Preferably, the second band 7 is pre-determined from the first band 6 from its first end 11 where the second opening line L2 is located at the first edge 2 (ie at the part 2a). It is formed so as to extend up to a distance of.

  Therefore, the first opening line “L1” and the second opening line “L2” do not intersect at any point.

  In other words, the second opening line “L2” extends from the end 11 and is close to the first tape 6 but spaced from the first tape 6 and spaced therefrom. Go.

  Note that the user grasps the portion 2a of the first edge portion 2 disposed between the (first) end portion 6a of the first band 6 and the end portion 11 of the second opening line “L2”. The portion to be (or tab 104 in use) is defined.

  Preferably, the second band 7 has a quadrilateral shape whose sides are defined by the first end segment 7a, by the second end segment 7b and by the two side segments 7c, 7d. . The two side segments 7c and 7d connect the first end segment 7a and the second end segment 7b to each other.

  In the illustrated embodiment, the second band 7 has a trapezoidal shape, and the side segments 7c, 7d define the base of the trapezoid. More precisely, the second band 7 has a right trapezoidal shape whose oblique sides are defined by the first end segment 7a (ie the portion 2a of the first edge 2 of the sheet 1).

  Therefore, the second opening line “L2” is preferably by one of the two side segments 7c, 7d of the second band 7 and more particularly far from the first band 6. It is defined by the side segment 7d.

  According to an aspect of the present invention, the opening means 5 includes a third band 9. The third band 9 hits the first band 6 at at least one junction 10 and extends at least partially within the first portion 1 a of the sheet 1.

  The third band 9 defines a third opening line “L3”. The third unsealing line “L3” extends from the joining point 10 in the first portion of the sheet 1a so as to be separated from the first unsealing line “L1” (that is, from the first band 6).

Thus, advantageously, three or more opening lines can extend from the shared first band 6;
The first opening line “L1” extends in the peripheral direction along the packaging direction “A”;
-The second opening line "L2" is spaced from the first opening line "L1", at least over its first stretch, preferably over its entire length, inside the second part 1b of the sheet 1 Extend
The third opening line “L3” extends inside the first part 1a of the sheet so as to be spaced apart from the first opening line “L1”;

  Preferably, the second opening line “L2” and the third opening line “L3” both extend toward the second edge 3 of the sheet 1 and are equal and the first opening line. It is inclined at the opposite angle to “L1”.

  The first unsealing line “L1” and the second unsealing line “L2” have the origin at the intersection 8 between the first band 6 and the second band 7 and the second edge 3 Defines a branch extending toward (i.e., "V").

  On the other hand, the third opening line “L3” preferably defines an extension of the first opening line “L1” and the first opening line “L1” is at a predetermined angle with respect to the first opening line “L1”. It extends from the junction 10 between the band 6 and the third band 9 toward the second edge 3 of the sheet 1.

  Structurally, the third band 9 preferably has at least one end segment 9a. The end segment 9 a extends inside the first part 1 a of the sheet 1 and starts from the first band 6, ie at the junction 10.

  The end segment 9a extends away from the junction 10 so as to define a third opening line “L3”.

  More precisely, the third band 9 (similar to the second band 7) is far from the first edge segment 9a close to the first edge 2 of the sheet and from the first edge 2 of the sheet. It extends between the second end segment 9b.

  Accordingly, the third opening line “L3” is defined by the first end segment 9 a of the third band 9.

  The third band 9 extends from the first end segment 9a and away from the second portion 1b of the sheet.

  More precisely, the third band 9 is transverse to the first end segment 9a (ie to the third opening line “L3”) in the transverse direction (preferably at a right angle). Extends toward the portion 1b of the.

  In more detail (and similar to the second band 7), the third band is edged by the first end segment 9a, by the second end segment 9b and by the two side segments 9c. Has a quadrilateral shape defined. The two side segments 9c connect the first end segment 9a and the second end segment 9b to each other.

  In a preferred embodiment, the second opening line “L2” is defined by the side segment 7c of the second band 7, while the third opening line “L3” is the third band 9 It is defined by the first end segment 9a.

  Preferably, the third band 9 has a trapezoidal shape, and the side segments 9c define the base of the trapezoid. In the illustrated embodiment, the third band 9 has a right trapezoidal shape with diagonal sides defined by the second end segment 9b.

  In other words, the third band 9 has a width equal to the length of the first end segment 9a and corresponding to the third opening line “L3”.

  It should be noted that the second end segment 9b of the third band 9 defines a portion 3a of the second edge 3 of the sheet.

  More specifically, the first end segment 7a of the second band 7 and the second end segment 9b of the third band 9 are respectively the portion 2a of the first edge 2 of the sheet and the sheet A portion 3a of the second edge 3 is defined. Both portions 2a and 3a extend from the first band 6 to the inside of the second portion 1b of the sheet 1 over a predetermined length.

  Furthermore, the second band 7 and the third band 9 have the same width (that is, a dimension perpendicular to the extending direction). Preferably, this width is equal to the dimension of the third opening line “L3”.

  Preferably, the first band 6 is defined by a reinforcing tape 12 that is fixed to the sheet 1. On the other hand, the second band 7 and the third band 9 are defined by a band 13. The band 13 is at least partially overlapped (i.e., placed on) the tape 12 of the first band 6 (at the intersection 8 and at the junction 10) and is also fixed to the sheet 1.

  Alternatively, the tape 12 of the first band 6 may be partially overlapped (ie, placed on) the second band 7 and the band 13 of the third band 9.

  Advantageously, the foregoing makes it easy to produce the sheet 1 using a simple and reliable method.

  In this regard, the subject of the invention also includes a method for producing the packaging material sheet 1.

  This method comprises a preliminary step of providing a continuous film 14 of packaging material (which can be heat sealed) and a material that can be joined to the film 14 (and preferably has a tear strength greater than the tear strength of the film). And a preliminary step of providing a band 13 made of a material that can be joined to the film 14 (and preferably has a tear strength greater than the tear strength of the film).

  The band 13 may be provided in a cut state or may be cut from a continuous roll during processing.

  The band 13 is wider than the tape 12.

  Next, the film 14 is advanced along a predetermined feeding direction “B”. Preferably, the feeding direction “B” corresponds to the packaging direction “A”.

  As the film 14 advances, the tape 12 is overlapped and fixed to the film 14 in a line parallel to the feeding direction “B”.

  In this way, the tape 12 divides the film 14 into the first portion 14a and the second portion 14b on the opposite side across the tape 12 itself. The portions 14 a and 14 b of the film 14 correspond to the portions 1 a and 1 b of the sheet 1.

  Preferably, the tape 12 is secured by chemical means, i.e., for example, by an adhesive. In this regard, the tape 12 is a tape coated with an adhesive. The tape 12 is preferably attached to the film as the film moves, that is, as the film 14 advances along the feeding direction “B”.

  Before or after the tape 12 is applied, each band 13 is overlaid on the film 14 such that each band 13 is spaced from the next band and has an intersection area 13a with the tape 12, And there is a step of fixing each band 13 apart.

  Note that the phrase “fixed apart” is used to mean that the bands 13 are arranged so that the bands 13 are spaced from each other along the feeding direction “B”.

  More precisely, the step of stacking and fixing the bands 13 apart from each other is the step of positioning the bands 13 at a predetermined distance from each other in order to form a single reinforcing band 13 at a predetermined interval. This is done by repeating the steps of overlapping and fixing to 14.

  Thus, after the two overlapping and securing steps, the film 14 has a continuous band extending along the unwinding direction “B”, ie, tape 12 and sequentially along the film 14 (and along the tape 12). And) a series of separate bands 13 arranged.

  Preferably, the intersection area 13a includes at least one first stretch 13b located in the first portion 14a of the film 14, and at least one second stretch 13c located in the second portion 14b of the film 14. It is arranged between.

  Accordingly, each band 13 extends in the transverse direction with respect to the tape 12 and intersects the tape 12 in the intersection area 13a.

  More specifically, the intersecting area 13a is a substantially linear segment extending between two ends along the extending direction of the tape 12, the first end corresponds to the intersection point 8, and the first The end of 2 corresponds to the junction 10. Note that both the intersection point 8 and the junction point 10 are described as described above in the description of the sheet 1.

  Preferably, each band 13 is inclined at a predetermined angle different from 90 ° with respect to the tape 12 (and thus with respect to the feeding direction “B”).

  In the preferred embodiment, each band 13 is defined by an elongated polygonal element 16. The element 16 has at least two long sides 16a extending along the main axis “C” of the polygonal element 16 and at least one short side 16b connecting the long sides 16a to form two vertices 17. Have.

  Preferably, the polygonal element 16 has a rectangular shape.

  Thus, the step of overlapping and securing each band 13 is done by positioning each polygonal element 16 on the film 14 such that one of the vertices 17 is superimposed (or intersected) on the tape 12. . Furthermore, the polygonal element 16 is oriented such that its main axis “C” is inclined at a predetermined angle with respect to the delivery direction “B” (ie, with respect to the tape 12).

  According to what has been described above, the axis “C” is inclined with respect to the tape 12 at an angle different from 90 °.

  Alternatively, and with particular reference to FIG. 7, the band 13 may be on the film at the same angle as described above, but with both vertices 17 of the polygonal element 16 located at the first portion 14a of the film 14. It may be positioned.

  In this way, the third opening line “L3” is inclined at an angle opposite to the above angle, that is, the third opening line “L3” is a side segment of the third band 9. Is defined at least in part by 9 c and extends towards the first edge 2.

  In any case, like the tape 12, the band 13 is also preferably secured by chemical means, ie, for example, by an adhesive. In this regard, the band 13 is preferably coated with an adhesive.

  Once the tape 12 and the strip 13 are positioned, the method according to the invention comprises the step of cutting the film 14 along a cutting line “T” transverse (preferably perpendicular) to the unwinding direction.

  The cutting step includes dividing each band 13 into a first one-side portion 15a that includes a first stretch 13b and a second one-side portion 15b that at least partially includes a second stretch 13c. Performed (ie, performed) in band 13.

  More precisely, after the cutting step, the first one-sided portion 15a of each band 13 is partly on the first part 14a of the film 14 and partly on the second part 14b of the film 14. Positioned.

  Further, following the cutting step, the second one-side portion 15b of each band 13 is completely positioned on the second portion 14b of the film 14.

  Preferably, the second one side portion 15 b of the band 13 extends from the tape 12.

  Therefore, the cutting step is preferably performed in the intersection area 13a.

  In addition, the edge parts 2 and 3 of the packaging material sheet 1 which concern on this invention are produced by the step cut | disconnected.

  More precisely, each cutting step produces a first edge 2 of one sheet 1 and a second edge 3 of the next sheet 1.

  Also, as a result of the cutting step, the long side 16a of the polygonal element 16 is divided, and the side segments 7c, 9c of the second band 7 and the third band 9 of the opening means 5 are formed respectively. Is done.

  Thus, each sheet 1 is a result of two successive cutting steps being performed on two successive bands 13.

  As described above, the packaging material sheet 1 produced using the method according to the present invention is preferably used for producing the exterior 101 of the packaging box 100 for smoking products, but is not limited thereto.

  Actually, the packaging box 100 includes a container 102 and an exterior 101 that is packaged around the container 102.

  Inside, the container 102 has a group of smoking products (not shown), preferably tobacco.

  In the illustrated embodiment, the container 102 has a substantially parallelepiped shape. Accordingly, the container 102 has a front wall portion, a back wall portion, a bottom wall portion, an upper wall portion, and two side surfaces.

  The container can then be divided into a first one-side portion 102a and a second one-side portion 102b.

  More specifically, the container 102 has at least an upper portion and a storage portion. The upper portion defines a first one-side portion 102a and can be opened by a user to remove the smoking product, and the storage portion defines a second one-side portion 102b and contains the smoking product .

  The upper portion 102a preferably defines a lid that is hingedly attached to the storage portion 102b at the back wall.

  Alternatively, the upper portion may be defined by a resealable label or other known opening system.

  According to the present invention, the exterior 101 is defined by the packaging material sheet 1 produced as described above, and is wrapped around the container 102.

  More precisely, the first band 6 of the opening means 5 of the sheet 1 extends around the container 102 in the peripheral direction. Accordingly, the packaging direction “A” of the sheet 1 passes in an annular shape around the axis “D” of the longitudinal container 102 in the center.

  In more detail, the first portion 1a and the second portion 1b of the sheet 1 overlap with the first one-side portion 102a and the second one-side portion 102b of the container 102, respectively.

  Therefore, referring to the illustrated embodiment, the first portion 1a and the second portion 1b of the seat 1 overlap with the upper portion and the storage portion, respectively.

  Thus, advantageously, the user need only act on the first band 6 to create three or more opening lines in the sheet 1 that extend along both the storage and upper portions. Therefore, the exterior 101 of the packaging box 100 can be easily detached from the container 102 by the sheet 1 according to the present invention.

  Note that the packaging material sheet 1, that is, the exterior 101 has two flaps 103. The two flaps 103 are close to the first edge 2 and the second edge 3, respectively, so that the first edge 2 is at least in the first band 6 and the second band 7, the opening line "L1 ”,“ L2 ”,“ L3 ”are heat sealed together to define a tab or gripping portion 104 that can be gripped by the user to tear the sheath 101.

  Preferably, the grip tab 104 is located on one side of the container 102.

  The present invention achieves the above objectives and provides significant advantages.

  In fact, the three bands creating three separate opening lines make it very easy for the user to remove the outer packaging from the packaging box.

  Furthermore, the method according to the invention makes it possible to produce three bands in only two steps, namely the step of fixing the tape and the step of fixing the band, thus facilitating and speeding up the manufacturing process. To do.
