Fig. 2 is an external perspective view of a back side of the package 1. The package 1 is a wrapping body having a box shape and wraps a plurality of cigarette. The package 1 is formed by including an inner wrapping box 2 that directly wraps the cigarettes, and an outer wrapping box 3 that wraps the inner wrapping box 2 except for a top closed face 21 of the inner wrapping box 2, and is referred to as a so-called soft package or soft pack.
The inner wrapping box 2 is formed of, for example, inner wrapping paper having an outer face coated with aluminum foil, and a bottom face and the top closed face 21 thereof form a mouth folded unit 22 by folding the inner wrapping paper. The outer wrapping box 3 is formed of outer wrapping paper where a pattern, a product name and the like are printed on an outer face thereof, and wraps the inner wrapping box 2 in such a manner as to cover side faces and the bottom face of the inner wrapping box 2 in a state where the top closed face 21 of the inner wrapping box 2 is exposed. A bottom face of the outer wrapping box 3 also forms a mouth folded unit 22 by folding a part of the outer wrapping paper similarly to the top closed face 21 of the inner wrapping box 2. Here, reference sign 31 denotes a front face of the outer wrapping box 3, and reference sign 32 denotes a rear face of the outer wrapping box 3. Further, reference sign 33a denotes a left side face of the outer wrapping box 3, and reference sign 33b denotes a right side face of the outer wrapping box 3. The front face 31 and the rear face 32 of the outer wrapping box 3 are parallel to each other, and are respectively orthogonal to the top closed face 21 of the inner wrapping box 2. In the present embodiment, the top closed face 21 of the inner wrapping box 2, the front face 31 of the outer wrapping box 3, and the rear face 32 of the outer wrapping box 3 respectively correspond to a first face, a second face and a third face according to the present invention. Further, the inner wrapping box 2 and the outer wrapping box 3 in the present embodiment correspond to a wrapping unit in the present invention. Hereinafter, in the present specification, a front face side of the package 1 is defined as a "front", and a back face side is defined as a "rear". Further, respective directions of an up, down, front, rear, left and right of the package 1 are defined as illustrated in Fig. 1. A left-right direction of the package 1 is referred to as a "width direction", and an up-down direction is referred to as a "height direction". Fig. 1 and Fig. 2 illustrate the respective directions of the up, down, front, rear, left and right.
As illustrated in Fig. 1 and Fig. 2, the package 1 is sealed by being entirely covered with an exterior film 4 when not opened. The exterior film 4 may be a transparent film formed from a material such as polypropylene, cellophane, and polyethylene terephthalate, for example. The exterior film 4 is provided with an opening tape (also referred to as a "tear tape") 5. The opening tape 5 is a band member that is wound in such a manner as to go around along one circumference surface of the package 1, and is pasted on a back face (inner face) side of the exterior film 4. The opening tape 5 is used to tear and open the exterior film 4 by a tip end portion (not illustrated) being pulled by a user (smoker) at a time of opening the package 1. Reference sign 4a denotes an upper side portion at an upper side from the opening tape 5, that is, close to the top closed face 21 (mouth folded unit 22), in the exterior film 4. Fig. 3 is a view illustrating a state where the package 1 is opened. Fig. 3 illustrates a state where the exterior film 4 is torn with the opening tape 5 as a starting point, and the upper side portion 4a of the exterior film 4 is removed. In the state illustrated in Fig. 3, the top closed face 21 (mouth folded unit 22) of the inner wrapping box 2 in the package 1 is exposed to outside.
Reference sign 10 illustrated in Fig. 1 to Fig. 3 denotes a sealing seal. The sealing seal 10 has a band shape, and is bonded in such a manner as to straddle the top closed face 21 (mouth folded unit 22) of the inner wrapping box 2, and the front face 31 and the rear face 32 of the outer wrapping box 3. The sealing seal 10 crosses a center in a width direction of the top closed face 21 (mouth folded unit 22) of the inner wrapping box 2, and both ends thereof are folded perpendicularly to the front face 31 and the rear face 32 of the outer wrapping box 3. The sealing seal 10 seals the top closed face 21 (mouth folded unit 22) of the package 1.
In order to extract a cigarette from the package 1, the exterior film 4 is opened as illustrated in Fig. 3, after which, one side of the mouth folded unit 22 is cut out with the sealing seal 10 left, of the mouth folded unit 22 formed on the top closed face 21 of the inner wrapping box 2, and an extraction port for cigarettes is formed. Accordingly, the cigarettes wrapped in the inner wrapping box 2 in the package 1 are exposed from the extraction port, and the cigarettes can be extracted.
The sealing seal 10 in the present embodiment is a double sealing seal in which sealing seals of paper are stacked in two layers. Hereinafter, a detailed structure of the sealing seal 10 will be described. Fig. 4 is an exploded view of the sealing seal 10 according to embodiment 1. The sealing seal 10 has a lower sealing seal unit 11 that is bonded to the package 1, and an upper seal unit 12 that is stacked on the lower sealing seal unit 11 and is bonded to the lower sealing seal unit. The upper seal unit 12 includes a first upper seal unit 13 and a second upper seal unit 14.
As illustrated in Fig. 4, the lower sealing seal unit 11 is a band body having a rectangular shape, and a broken line indicates a folding position. Reference sign LB1 illustrated in Fig. 4 denotes a first folding line that is folded in a first edge portion E1 located in a boundary between the front face 31 of the outer wrapping box 3 and the top closed face 21 (mouth folded unit 22) of the inner wrapping box 2. Reference sign LB2 denotes a second folding line that is folded in a second edge portion E2 located in a boundary between the rear face 32 of the outer wrapping box 3 and the top closed face 21 (mouth folding unit 22) of the inner wrapping box 2.
Hereinafter, in the lower sealing seal unit 11, a rectangular region between the first folding line LB1 and the second folding line LB2 will be referred to as a lower first region 111, a rectangular region between one short side SS1 and the first folding line LB1 will be referred to as a lower second region 112, and a rectangular region between the second folding line LB2 and the other short side SS2 will be referred to as a lower third region 113. The lower second region 112 of the lower sealing seal unit 11 is bonded to the front face 31 of the outer wrapping box 3, the lower first region 111 is bonded to the top closed face 21 (mouth folded unit 22) of the inner wrapping box 2, and the lower third region 113 is bonded to the rear face 32 of the outer wrapping box 3. In other words, as illustrated in Fig. 3, the lower sealing seal unit 11 is bonded to the package 1 in such a manner as to straddle the front face 31 of the outer wrapping box 3, the top closed face 21 (mouth folded unit 22) of the inner wrapping box 2, and the rear face 32 of the outer wrapping box 3.
Next, details of the upper seal unit 12 of the sealing seal 10 will be described. As illustrated in Fig. 4, the upper seal unit 12 (a combination of the first upper seal unit 13 and the second upper seal unit 14) is substantially congruent with the lower sealing seal unit 11 as a whole. Fig. 5 is a top view of the upper seal unit 12 of the sealing seal 10 according to embodiment 1. Reference sign 13a denotes a top face of the first upper seal unit 13. Reference sign 14a denotes a top face of the second upper seal unit 14. The upper seal unit 12 is a band body of paper having a rectangular shape as a whole, and broken lines indicate folding positions. In the first upper seal unit 13, reference sign LU1 illustrated in Fig. 5 is a first folding line that is folded in the first edge portion E1 of the package 1. Reference sign LU2 is a second folding line that is folded in the second edge portion E2 of the package 1. Hereinafter, in the first upper seal unit 13, a rectangular region between the first folding line LU1 and the second folding line LU2 will be referred to as an upper first region 131, and a region between a boundary portion BD from the second upper seal unit 14 in the first upper seal unit 13, and the first folding line LU1 will be referred to as an upper second region 132, and a rectangular region between the second folding line LU2 and a short side SS3 will be referred to as an upper third region 133.
Here, the first upper seal unit 13 and the second upper seal unit 14 in the upper seal unit 12 are locally connected via easy cutting units 15 as illustrated in an enlarged view in Fig. 5. The easy cutting unit 15 is called a so-called nick stop, and can separate the first upper seal unit 13 and the second upper seal unit 14 by being cut (broken) by an external force. In the boundary portion BD between the first upper seal unit 13 and the second upper seal unit 14, slits SL are formed except for parts where the easy cutting portions 15 are formed.
Here, a separation dimension (length dimension of the upper first region 131) between the first folding line LU1 and the second folding line LU2 in the first upper seal unit 13 is equal to a separation dimension (length dimension of the lower first region 111) between the first folding line LB1 and the second folding line LB2 in the lower sealing seal unit 11, and corresponds to a depth dimension of the package 1 (top closed face 21). However, due to a thickness of paper, the first upper seal unit 13 may be folded with a slight margin as compared with the lower sealing seal unit 11, and therefore, the separation dimension (length dimension of the upper first region 131) between the first folding line LU1 and the second folding line LU2 in the first upper seal unit 13 may be set to be a slightly larger than the separation dimension (length dimension of the lower first region 111) between the first folding line LB1 and the second folding line LB2 in the lower sealing seal unit 11. The upper first region 131 in the first upper seal unit 13 is stacked on the lower first region 111 of the lower sealing seal unit 11 and is glued (bonded) to the lower first region 111. Further, the upper second region 132 in the first upper seal unit 13 is stacked on the lower second region 112 in the lower sealing seal unit 11, and is glued to the lower second region 112. Further, the upper third region 133 in the first upper seal unit 13 is stacked on the lower third region 113 in the lower sealing seal unit 11 and is glued to the lower third region 113.
Here, the separation dimension (length dimension of the upper second region 132) between the boundary portion BD and the first folding line LU1 in the first upper seal unit 13 is smaller as compared with the separation dimension (length dimension of the lower second region 112) between the short side SS1 and the first folding line LB1 in the lower sealing seal unit 11. Accordingly, the upper second region 132 of the first upper seal unit 13 is bonded to the lower second region 112 in such a manner as to cover a part of the lower second region 112 of the lower sealing seal unit 11. In the present embodiment, the second upper seal unit 14 is bonded to the lower second region 112 in such a manner as to cover at least a part of an uncovered region that is not covered with the upper second region 132 of the first upper seal unit 13, in the lower second region 112 in the lower sealing seal unit 11. In the example illustrated in Fig. 4, the second upper seal unit 14 is stacked in such a manner as to cover a whole (all) of the uncovered region in the lower second region 112 of the lower sealing seal unit 11. Note that the separation dimension (length dimension of the upper third region 133) between the short side SS3 and the second folding line LU2 in the first upper seal unit 13 is equal to the separation dimension (length dimension of the lower third region 113) between the short side SS2 and the second folding line LB2 in the lower sealing seal unit 11. However, due to the thickness of paper, the first upper seal unit 13 may be folded with a slight margin as compared with the lower sealing seal unit 11, and therefore, the separation dimension (length dimension of the upper third region 133) between SS3 and the second folding line LU2 may be set to be slightly larger than the separation dimension (length dimension of the lower third region 113) between the short side SS2 and the second folding line LB2 in the lower sealing seal unit 11.
Here, in the upper second region 132 in the first upper seal unit 13, a picking tab 16 is provided at a tip end portion located on a boundary portion BD side from the second upper seal unit 14. The picking tab 16 is a tongue that protrudes from other parts to be easily picked when a user (smoker) peels the upper seal unit 12 (first upper seal unit 13) from the lower sealing seal unit 11. The picking tab 16 is provided to protrude to an opposite direction (opposite side) to the first folding line LU1 from a tip end portion of the upper second region 132 in the first upper seal unit 13. Further, the picking tab 16 has a trapezoidal shape, and a shape thereof is defined by a tab upper side 161, a tab first oblique side 162, and a tab second oblique side 163. The tab upper side 161 of the picking tab 16 is parallel to the first folding line LU1, and the tab first oblique side 162 and the tab second oblique side 163 incline to the tab upper side 161. As illustrated in Fig. 5, in the upper seal unit 12, the picking tab 16 of the first upper seal unit 13 is locally connected to the second upper seal unit 14 via the easy cutting unit 15.
Here, explaining a relationship between the upper second region 132 in the first upper seal unit 13 and the second upper seal unit 14 in more detail, a recessed unit 17 in a trapezoidal shape that receives the picking tab 16 is formed on the boundary portion BD side in the second upper seal unit 14. The recessed unit 17 has a shape thereof defined by a recessed unit upper side 171, a recessed unit first oblique side 172, and a recessed unit second oblique side 173. The recessed unit upper side 171, the recessed unit first oblique side 172, and the recessed unit second oblique side 173 of the recessed unit 17 are respectively disposed to face the tab upper side 161, the tab first oblique side 162, and the tab second oblique side 163 of the picking tab 16. The easy cutting portion 15 locally connects the tab first oblique side 162 and the tab second oblique side 163 of the picking tab 16 and the recessed unit first oblique side 172 and the recessed unit second oblique side 173 on a recessed unit 17 side that face the tab first oblique side 162 and the tab second oblique side 163. Further, as illustrated in Fig. 5, the easy cutting portion 15 extends along an oblique direction to the first folding line LU1 in the first upper seal unit 13. Note that in the present embodiment, the easy cutting portion 15 is provided in each of the tab first oblique side 162 and the tab second oblique side 163 of the picking tab 16, but a number of easy cutting portions 15 is not especially limited. For example, a plurality of easy cutting portions 15 may be provided in each of the tab first oblique side 162 and the tab second oblique side 163. Further, the easy cutting portion 15 may be provided in only either one of the tab first oblique side 162 and the tab second oblique side 163. Further, in the present embodiment, in the boundary portion BD of the first upper seal unit 13 and the second upper seal unit 14, regions sandwiched by the slits SL are formed as the easy cutting portions 15, but the easy cutting portions 15 may be formed by applying half-cut processing along the boundary portion BD.
Next, details of the upper third region 133 in the first upper seal unit 13 will be described. In the upper third region 133, a pair of slits 18a and 18b are provided in a vicinity of the second folding line LU2. The slits 18a and 18b penetrate through the upper third region 133 in the first upper seal unit 13 in a thickness direction. The slits 18a and 18b are provided to extend parallel to the second folding line LU2. In the present embodiment, the two slits 18a and 18b are provided in the upper third region 133, but a number of the slits is not especially limited.
Reference sign BP illustrated in Fig. 4 denotes a gluing part of the upper seal unit 12 (the first upper seal unit 13, the second upper seal unit 14) to the lower sealing seal unit 11. In the sealing seal 10 in the present embodiment, an adhesive glue is applied to points, and thereby the upper seal unit 12 (the first upper seal unit 13, the second upper seal unit 14) is bonded to the lower sealing seal unit 11 to be peelable. In the example illustrated in Fig. 4, the picking tab 16 of the upper second region 132 in the first upper seal unit 13 is in an unbonded state to the lower second region 112 of the lower sealing seal unit 11.
Fig. 6 is a view illustrating a back face 13b of the first upper seal unit 13 of the sealing seal 10 according to embodiment 1. The back face 13b of the first upper seal unit 13 is a bonding face that is bonded to a top face of the lower sealing seal unit 11. On the back face 13b of the first upper seal unit 13, information codes (not illustrated) coding information concerning a campaign, information on URL and an electronic mail address for accessing a campaign site are printed. The information code is preferably printed on the back face 13b corresponding to the upper first region 131 having a largest area of the first upper seal unit 13. The information code may be a QR code (registered trademark) that is a kind of a two-dimensional code, for example. Further, instead of the two-dimensional code, a one-dimensional barcode may be printed on the back face 13b of the first upper seal unit 13.
In the package 1 configured as above, the sealing seal 10 and the top closed face 21 (mouth folded unit 22) of the package 1 are exposed as illustrated in Fig. 3 by the upper side unit 4a of the opening tape 5 in the exterior film 4 being removed. As illustrated in Fig. 3, the sealing seal 10 (the lower sealing seal unit 11) is bonded in such a manner as to straddle the front face 31 of the outer wrapping box 3, the top closed face 21 (mouth folded unit 22) of the inner wrapping box 2 and the rear face 32 of the outer wrapping box 3. According to the sealing seal 10 of the package 1 in the present embodiment, the picking tab 16 is provided at the tip end portion of the upper second region 132 in the first upper seal unit 13, and therefore, the user (smoker) can easily peel the first upper seal unit 13 from the lower sealing seal unit 11 as illustrated in Fig. 7A and Fig. 7B by picking the picking tab 16 and pulling up the picking tab 16. Further, the package 1 including the sealing seal 10 in the present embodiment can be manufactured by customizing an existing package packing machine, and is highly useful as a tool that can add product information without enormous investment in machinery and equipment. Further, the package 1 can be manufactured by replacing an ordinary sealing seal with the sealing seal 10 according to the present embodiment, and therefore reduction in manufacture efficiency of the package 1 by a packing machine can also be reduced.
At this time, a linear picking edge portion E3 is formed by the tab upper side 161 in the picking tab 16 in the first upper seal unit 13, so that a finger of the user (smoker) is more easily caught by the picking tab 16 (picking edge portion E3), and the first upper seal unit 13 can be more easily peeled from the lower sealing seal unit 11. As the shape of the picking tab 16 having the linear picking edge portion E3 as described above, a trapezoidal shape can be preferably cited. Note that in the boundary portion BD from the second upper seal unit 14 in the upper second region 132 of the first upper seal unit 13, edge portions that are located at both sides of the picking tab 16, that is, edge portions located at roots of the picking tab 16 are referred to as "tab base end edge portions E4". The picking edge portion E3 and the tab base end edge portion E4 are parallel to the first folding line LU1 and the first edge portion E1 in the first upper seal unit 13.
Further, according to the present embodiment, the lower second region 112 of the lower sealing seal unit 11 is folded in an orthogonal direction from the lower first region 111 with the first edge portion E1 as a boundary and is bonded to the front face 31 of the outer wrapping box 3. Further, the upper second region 132 of the first upper seal unit 13 is folded in an orthogonal direction from the upper first region 131 to be along the lower second region 112 of the lower sealing seal unit 11 with the first edge portion E1 as a boundary. In this way, the upper second region 132 of the first upper seal unit 13 is folded in the orthogonal direction from the upper first region 131, whereby a restoration force can be caused to act in a direction to peel the upper second region 132 of the first upper seal unit 13 from the lower second region 112 of the lower sealing seal unit 11. At this time, the picking tab 16 is provided to protrude toward an opposite direction (opposite side) to the first edge portion E1, from the tip end portion of the upper second region 132 in the first upper seal unit 13. Accordingly, a direction in which the picking tab 16 of the first upper seal unit 13 is picked and turned up, and the direction of the restoration force acting on the upper second region 132 of the first upper seal unit 13 correspond to each other, and the first upper seal unit 13 can be more easily peeled from the lower sealing seal unit 11.
In particular, according to the present embodiment, the picking tab 16 is provided close to the first edge portion E1 of the package 1. Accordingly, the restoration force of the upper second region 132 acting in the direction to turn up the picking tab 16 can be further increased. Here, a separation dimension distance (hereinafter, referred to as a "first separation distance") D1 (refer to Fig. 5) between a root portion of the picking tab 16, that is, the tab base end edge portion E4 and the first edge portion E1 (first folding line LU1) is preferably set in a range of 0 mm or more and 4 mm or less, is more preferably set in a range of 0 mm or more and 3 mm or less, and is especially preferably set in a range of 0 mm or more and 2 mm or less. When the first separation distance D1 becomes longer than 4 mm, a repulsive force of paper for making it easy to turn up the first upper seal unit 13 is unlikely to be sufficiently obtained. By making the first separation distance D1 4 mm or less, a preferable repulsive force is obtained in the upper second region 132 of the first upper seal unit 13, and by making the first separation distance D1 3 mm or less, a more preferable repulsive force is obtained. Further, by making the first separation distance D1 2 mm or less, an optimal state for turning up the first upper seal unit 13 is brought about. By adjusting the first separation distance D1 between the tab base end edge portion E4 located at the root of the picking tab 16 and the first edge portion E1 (first folding line LU1) in the above described range, a magnitude of the restoration force acting in the direction to peel the upper second region 132 of the first upper seal unit 13 from the lower second region 112 of the lower sealing seal unit 11 can be sufficiently obtained, and peeling easiness of the first upper seal unit 13 can be enhanced.
Next, mentioning a preferable range of a nick portion length (hereinafter, referred to as a "nick length") L1 (refer to the partially enlarged vie in Fig. 5) of the easy cutting unit 15, the nick portion is likely to be cut during manufacture when the nick length L1 is less than 0.3 mm, and when the nick length L1 becomes more than 0.7 mm, paper is likely to be cut in an undesired portion (portion except for the nick) when the user picks the package 1 after manufacture of the package 1. Therefore, setting the nick length L1 in a range of 0.3 to 0.7 mm is preferable, and setting at 0.5 mm is optimal. Further, when a separation distance (hereinafter, referred to as a "second separation distance") D2 (refer to the partially enlarged view in Fig. 5) between the picking edge portion E3 and the tab base end edge portion E4 in the picking tab 16 becomes longer than 3 mm, the repulsive force of the paper increases, and the tab is likely to be turned freely, whereas when the separation distance D2 is shorter than 1 mm, the picking tab 16 is likely to be difficult to pick. Therefore, the second separation distance D2 is preferably set within a range of 1 mm or more and 3 mm or less.
Here, mentioning a width (hereinafter, referred to as a "picking tab tip end width") L2 (refer to the partially enlarged view in Fig. 5) of the picking edge portion E3 in the picking tab 16, the picking tab tip end width L2 is preferably set at a dimension of 5 mm or more from a viewpoint of picking easiness of the picking edge portion E3.
Next, a width (hereinafter, referred to as a "picking tab base end width") L3 (refer to the partially enlarged view of Fig. 5) of the tab base end edge portion E4 in the picking tab 16 will be mentioned. The picking tab base end widths L3 of the respective tab base end edge portions E4 formed on both sides of the picking tab 16 is preferably set at a width of 1 mm or more from a viewpoint of allowing a precision error in manufacture of the sealing seal 10. Here, Fig. 8A is a view illustrating a sheet material S1 for forming the sealing seal 10 of a specification of forming the tab base end edge portions E4 on both sides of the picking tab 16. Fig. 8B is a view illustrating a sheet material S2 for forming the sealing seal 10 of a specification of not forming the tab base end edge portions E4 on both sides of the picking tab 16. Reference sign CLp illustrated in Figs. 8A and 8B denotes a design cutting line, and reference sign CLa denotes an actual cutting position. The sheet materials S1 and S2 are cut along the design cutting lines CLp in a manufacture process, and thereby are separated to individual sealing seals 10.
Figs. 8A and 8B illustrate cases in which when the individual sealing seals 10 are cut out from the sheet materials S1 and S2, the individual seals 10 are cut along the actual cutting positions CLa that are deviated from the design cutting lines CLp. First, in the sheet material S1 illustrated in Fig. 8A, the tab base end edge portions E4 are formed on both sides of the picking tab 16, whereby even when the actual cutting position CLa is somewhat deviated from the design cutting line CLp, the aforementioned picking tab base end width L3 is only slightly different from a design value and is not noticeable, and an error of the cutting position of the sealing seal 10 in the manufacture process is allowed. On the other hand, in the sheet material S2 illustrated in Fig. 8B, the tab base end edge portions E4 are not formed on both sides of the picking tab 16, and the picking tab base end width L3 is zero. Accordingly, when the actual cutting position CLa deviates from the design cutting line CLp, shapes at one end side and the other end side in the width direction of the sealing seal 10 become different and noticeable, in the sealing seal 10 after being cut out from the sheet material S2. In other words, an error of the cutting position of the sealing seal 10 in the manufacture process is not allowed, and there is a fear that the sealing seal 10 cannot be used as a product, and cannot help being discarded. There is no particular demerit in increasing the picking tab base end width L3 of the tab base end edge portion E4, but the picking tab base end width L3 can be decided in relation to a total width dimension of the sealing seal 10, the picking tab tip end width L2 and the like.
Further, an angle (hereinafter, referred to as an "oblique side inclination angle ") θ (refer to Fig. 5) formed by the tab first oblique side 162 (tab second oblique side 163) connecting the picking edge portion E3 and the tab base end edge portion E4 in the picking tab 16, and the picking edge portion E3 is preferably 90° or more. By making the oblique side inclination angle θ of the picking tab 16 90° or more, it can be made harder for the picking tab 16 itself to tear, with a spot of the easy cutting unit 15 (nick stop) as a start point. An upper limit angle of the oblique side inclination angle θ in the picking tab 16 can be properly calculated based on respective dimensions of the entire width of the sealing seal 10, the picking tab tip end width L2, the picking tab base end width L3, the second separation distance D2 and the like. As the entire width dimension of the sealing seal 10, 20 mm is often adopted as standard. Therefore, when the entire width of the sealing seal 10 is set as 20 mm, the picking tab tip end width L2 is set as 5 mm, the picking tab base end widths L3 of the respective tab base end edge portions E4 on both sides of the picking tab 16 are set as 1 mm, and the second separation distance D2 is set as 2 mm, the oblique side inclination angle θ is substantially 163°. In other words, the oblique side inclination angle θ of the picking tab 16 may be set in a range of 90° or more and 163° or less, and by setting the oblique inclination angle θ in the range like this, it is possible to balance the difficulty of tearing and picking easiness of the picking tab 16. Further, the oblique side inclination angle θ of the picking tab 16 is more preferably set in a range of 105° or more and 163° or less. Further, the oblique side inclination angle θ of the picking tab 16 is especially preferably set in a range (range of 135±5°) of 130° or more and 140° or less, and balance of tearing difficulty and picking easiness is especially excellent. It goes without saying that the entire width of the sealing seal 10 is not limited to 20 mm.
Further, according to the sealing seal 10 according to the present embodiment, the picking tab 16 of the first upper seal unit 13 is in a state of being unbonded to the lower sealing seal unit 11, and the picking tab 16 is locally connected to the second upper seal unit 14 adjacent to the picking tab 16 via the easy cutting units 15. According to this, the easy cutting unit 15 can be easily cut by picking and pulling up the picking tab 16, and the first upper seal unit 13 can be easily peeled off from the lower sealing seal unit 11 in a state where the second upper seal unit 14 is kept in a state of being bonded to the lower sealing seal unit 11.
Further, according to the sealing seal 10 according to the present embodiment, the picking tab 16 in the first upper seal unit 13 is formed into a trapezoidal shape, and the trapezoidal recessed unit 17 that is complementary to the picking tab 16 is formed at the tip end side of the second upper seal unit 14, and thereby the tab first oblique side 162 and the tab second oblique side 163 of the picking tab 16 and the recessed unit first oblique side 172 and the recessed unit second oblique side 173 that face the tab first oblique side 162 and the tab second oblique side 163 are connected by the easy cutting units 15. According to this, the easy cutting units 15 in the first upper seal unit 13 can be extended along the oblique direction to the first edge portion E1. By specifying the extending direction of the easy cutting unit 15 in this way, a component force of a tensile force that acts when the picking tab 16 is picked up acts in a direction to tear the easy cutting unit 15, so that it is possible to tear the easy cutting unit 15 preferably and to restrain a portion except for the easy cutting unit 15 in the first upper seal unit 13, for example, the region where the information code is printed on the back face 13b, from being torn. The easy cutting unit 15 in the first upper seal unit 13 may be extended along a perpendicular direction to the first edge portion E1, and by specifying the extending direction of the easy cutting unit 15 in this way, only the easy cutting unit 15 can be preferably cut when the picking tab 16 is picked up.
Further, according to the package 1 according to the present embodiment, the slits 18a and 18b are provided in the upper third region 133 in the first upper seal unit 13, so that the repulsive force of paper caused by pasting the upper third region 133 in the first upper seal unit 13 and the lower third region 113 of the lower sealing seal unit 11 is reduced, and folding can be performed smoothly. Further, a tensile force to the easy cutting unit 15 in the front face side of the package 1 is relaxed, and quality can be stabilized. The slits 18a and 18b may be formed as such microscopic incisions that cannot be recognized visually with naked eyes, and thereby reduction in appearance quality of the package 1 can be restrained. The slits 18a and 18b in the upper third region 133 of the first upper seal unit 13 are preferably provided in a vicinity of the second folding line LU2 (second edge portion E2). Further, the slits 18a and 18b may be formed in the upper first region 131 of the first upper seal unit 13 if only the slits 18a and 18b are in the vicinity of the second folding line LU2 (second edge portion E2), and the repulsive force of the paper caused by pasting the first upper seal unit 13 onto the lower sealing seal unit 11 can be reduced. Here, a separation distance (hereinafter, referred to as a "third separation distance") D3 (refer to Fig. 5) to the slits 18a and 18b from the second folding line LU2 (second edge portion E2) in the first upper seal unit 13 is preferably set in a range of 0 mm or more and 5 mm or less.
Here, as the third separation distance D3 is smaller, an effect of relaxing the repulsive force of the paper caused by pasting the upper third region 133 in the first upper seal unit 13 and the lower third region 113 of the lower sealing seal unit 11 can be increased. By setting the third separation distance D3 within 5 mm, the repulsive force of the paper described above can be reduced preferably. When the third separation distance D3 is 0 mm, it means that the slits 18a and 18b are formed on the second folding line LU2 in the first upper seal unit 13. Here, as the third separation distance D3 is smaller, the effect of relaxing the repulsive force of the paper can be increased as described above, but on the other hand, when a consumer picks the picking tab 16 and turns the first upper seal unit 13, a break may easily occur to the first upper seal unit 13 in the positions of the slits 18a and 18b. Thus, considering a balance of the effect of reducing the repulsive force of the paper caused by pasting the upper third region 133 in the first upper seal unit 13 and the lower third region 113 of the lower sealing seal unit 11, and difficulty of breaking the paper at the time of the user turning the first upper seal unit 13, the above described third separation distance D3 is especially preferably set in a range of 1.5 mm or more and 3.0 mm or less. The slits 18a and 18b may be provided on the top face side (the upper first region 131) of the package 1, or may be provided on a back face side (the upper third region 133) of the package 1. However, by providing the slits 18a and 18b on the back face side (the upper third region 133) of the package 1, there is provided an advantage of making the presence of the slits 18a and 18b less noticeable by the consumer, in the appearance of the package 1. Further, in the present embodiment, the slits 18a and 18b are provided to extend parallel to the second folding line LU2, and therefore, the repulsive force (restoration force) by folding of the upper third region 133 in the first upper seal unit 13 can be relaxed more preferably.
Further, according to the package 1 in the present embodiment, the inner wrapping box 2 and the outer wrapping box 3 are sealed by being covered with the exterior film 4, and the picking tab 16 in the first upper seal unit 13 of the sealing seal 10 is disposed above the opening tape 5 provided on the exterior film 4. According to this, when the exterior film 4 is torn and opened, the picking tab 16 of the first upper seal unit 13 can be exposed to outside, and therefore the picking tab 16 can be easily picked. Further, when the package 1 remains to be sealed, the entire package 1 is covered with the exterior film 4, and therefore the first upper seal unit 13 of the sealing seal 10 is not peeled illicitly. In other words, it is possible to regulate a fraudulent act such as a person who has not purchased the package 1 (tobacco product) properly peels the first upper seal unit 13 of the sealing seal 10 and applies for a campaign, for example.
While the preferred embodiment of the present invention is described as above, various modifications, alterations, combinations and the like of the sealing seal 10 and the package 1 according to the embodiment are enabled. For example, in the aforementioned embodiment, the shape of the picking tab 16 in the sealing seal 10 is trapezoidal, but other shapes may be adopted. Figs. 9A to 9C illustrate modified examples of the picking tab 16 in the sealing seal 10. In an example illustrated in Fig. 9A, the picking tab 16 has a rectangular shape instead of a trapezoidal shape. In more detail, in the picking tab 16 illustrated in Fig. 9A, the picking edge portion E3 and the tab base end edge portion E4 are connected by vertical edge portions E5 orthogonal to the picking edge portion E3 and the tab base end edge portion E4. Further, in an example illustrated in Fig. 9B, the picking tab 16 has an arc-shaped picking edge portion E3', and the tab base end edge portions E4 are respectively connected to both ends of the picking edge portion E3'. Further, in an example illustrated in Fig. 9C, the linear picking edge portion E3 and the tab base end edge portions E4 are connected via arc edge portions E6 in arc shapes. Further, while in the present embodiment, the case where the lower sealing seal unit 11 and the upper seal unit 12 in the sealing seal 10 are made of paper is explained as an example, the lower sealing seal unit 11 and the upper seal unit 12 may be made of a polymeric material. As the polymeric material forming the sealing seal 10, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate) and the like are illustrated. Further, the sealing seal 10 may be formed of bonded paper of the above described polymeric material and paper, or bonded paper of metal foil and paper. Further, in a paste (adhesive agent) that is used in bonding of the lower sealing seal unit 11 and the upper seal unit 12 in the sealing seal 10, for example, an ethylene vinyl acetate resin may be used for a main material, for example. From a viewpoint of peeling easiness of the upper seal unit 12 to the lower sealing seal unit 11, and reduction in undesired peeling, paste of an ethylene vinyl acetate resin is preferably used, but the paste is not limited to this. Further, in the present embodiment, the case of wrapping cigarettes in the package 1 is explained as an example, but an object to be wrapped is not especially limited. For example, other objects to be wrapped in the package 1 may be cigars, cigarillos, smokeless cigarettes such as snus, and electronic cigarettes. Further, an object to be wrapped that is not a tobacco product may be wrapped with the package 1 without being limited to the tobacco products as described above.
