Encapsulation

The present invention relates to double seals and packaging.

Tobacco products such as cigarettes are usually packaged in a package in a predetermined quantity. As for this kind of package, a so-called one-piece package is known as an inner wrapper formed of aluminum foil processed paper or the like, and an outer wrapper that covers the inner wrapper. As for wrapping paper, there are known those formed by thin paper called soft package or soft package, or those formed by assembling cardboard into a box shape called hard package, hard package or box body.

Usually, the soft packaging of cigarettes is to pack a plurality of cigarettes with inner wrapper, and then wrap the sides and bottom of the inner wrapper with wrapper. Next, the sealing paper is pasted so as to span the opening folded portion formed by relatively folding the inner wrapping paper and a part of the wrapping paper. When the cigarette is to be taken out, the inner wrapper of any one of the opening folds formed on both sides of the sealing paper can be torn to form a take-out port (opening portion) to take out the cigarette.

Here, there is known a soft package in which two layers of sealing paper are laminated (for example, refer to Patent Document 1). In the package shown in Patent Document 1, a second sealing paper is laminated on a first sealing paper pasted so as to span an opening fold and a part of the wrapping paper, and the second sealing paper is sealed by an adhesive having repeatable adhesive properties. The paper is pasted with respect to the first sealing paper in a state that can be pasted repeatedly. According to this package, after a part of the opening folded part forms an opening for taking out cigarettes, the second sealing paper pasted on the first sealing paper in a re-adhesive state can be torn off, and the second sealing paper can be used to cover it The opening can prevent the cigarette from falling off from the opening, prevent moisture from the cigarette in the package, and prevent volatilization of flavors.

In addition, the package 1 provided with the sealing member 10 of the present embodiment can be manufactured only by modifying an existing packaging and packaging machine, does not require a huge investment in machinery and equipment, and can be used as a tool for additional product information, and has high practicability. In addition, since a general sealing material can be replaced with the sealing material 10 of the embodiment to manufacture the package 1, it is also possible to suppress the reduction in the manufacturing efficiency of the package 1 caused by the packaging machine.

At this time, since the gripping tongue 16 of the first upper seal portion 13 is formed with a linear gripping edge E3 by the upper edge 161 of the tongue, the fingers of the user (smoker) can more easily grip and grip With the tongue piece 16 (grasping edge E3), the first upper seal portion 13 can be peeled from the lower seal portion 11 more easily. Regarding the shape of the gripping tongue 16 having the linear gripping edge E3 as described above, for example, a trapezoidal shape can be suitably used. In addition, in the boundary portion BD between the upper second region 132 of the first upper seal portion 13 and the second upper seal portion 14, the edges located on both sides of the grasping tongue 16 will be located on the grasping tongue. The edge of the base of the piece 16 is called "the base end edge of the tongue E4". The gripping edge E3 and the tongue base end edge E4 are parallel to the first fold line LU1 and the first edge E1 of the first upper seal portion 13.

In addition, according to the present embodiment, the lower second region 112 of the lower sealing portion 11 is bounded by the first edge E1 and is bent in the vertical direction from the lower first region 111 and then is on the front face 31 of the outer box 3. In addition, the upper second region 132 of the first upper sealing portion 13 is bounded by the first edge portion E1, and is folded in the vertical direction from the upper first region 131 along the lower second region 112 of the lower sealing portion 11 enter. In this way, by folding the upper second area 132 of the first upper sealing portion 13 in the vertical direction from the upper first area 131, the restoring force can be directed to seal the upper second area 132 of the first upper sealing portion 13 from the lower layer. The direction in which the second region 112 of the lower layer of the portion 11 peels off acts. At this time, the gripping tongue 16 protrudes from the front end portion of the upper second region 132 of the first upper seal portion 13 toward the opposite direction (opposite side) of the first edge portion E1. Therefore, the direction of grasping and pulling up the grasping tongue 16 of the first upper sealing portion 13 is consistent with the direction of the restoring force acting on the upper second region 132 of the first upper sealing portion 13, and the first upper sealing portion can be sealed The part 13 is more easily peeled off from the lower sealing part 11.

In particular, according to the present embodiment, the gripping tongue 16 is arranged close to the first edge E1 of the package 1. Therefore, it is possible to further increase the restoring force of the upper second region 132 acting in the direction in which the gripping tongue 16 is raised. Here, the base portion of the gripping tongue 16, that is, the distance between the base end edge E4 of the tongue and the first edge E1 (first fold line LU1) (hereinafter referred to as "first separation distance") D1 (Refer to Fig. 5) The range of 0 mm or more and 4 mm or less is preferable, the range of 0 mm or more and 3 mm or less is more preferable, and the range of 0 mm or more and 2 mm or less is more preferable. In addition, if the first separation distance D1 exceeds 4 mm, there is a possibility that the repulsive force of the paper for making the first upper layer sealing portion 13 easy to lift up may not be sufficiently obtained. In addition, by setting the first separation distance D1 to 4 mm or less, the upper second region 132 of the first upper sealing portion 13 can obtain an ideal rebound force, and setting the first separation distance D1 to 3 mm or less can obtain a more ideal Resilience. In addition, by setting the first separation distance D1 to be 2 mm or less, the first upper layer sealing portion 13 is cut out to be in the most appropriate state. By adjusting the first separation distance D1 between the tongue base end edge E4 and the first edge E1 (first fold line LU1) located at the root of the grasping tongue 16 to the above range, the direction to the first The magnitude of the restoring force acting in the direction in which the upper second region 132 of the upper sealing portion 13 peels from the lower second region 112 of the lower sealing portion 11 can improve the ease of tearing off the first upper sealing portion 13.

Next, referring to the preferred range of the length of the connection portion of the easy-to-cut portion 15 (hereinafter referred to as the "connection portion length") L1 (refer to the partial enlarged view of Fig. 5), the connection portion length L1 is less than 0.3mm If the length of the connection part L1 exceeds 0.7mm, after the package 1 is made, when the user wants to tear the package 1, the paper may be on the unexpected part (other than the connection part). Part) disconnect. Therefore, the connecting portion length L1 is preferably set in the range of 0.3 to 0.7 mm, and 0.5 mm is the most appropriate. Also, if the separation distance between the grabbing edge E3 of the grabbing tongue 16 and the tongue base end edge E4 (hereinafter referred to as the "second separation distance") D2 (refer to the partial enlarged view of FIG. 5) exceeds 3mm, the repulsive force of the paper may be too large to cause the tongue piece to be arbitrarily lifted, and if it is less than 1mm, the grasping tongue piece 16 may become difficult to grasp. Therefore, the second separation distance D2 is preferably set in the range of 1 mm or more and 3 mm or less.

Here, referring to the width of the grabbing edge E3 of the grabbing tongue 16 (hereinafter referred to as "the width of the tip end of the grabbing tongue") L2 (refer to the partial enlarged view of Figure 5), from grabbing From the viewpoint of the ease of grasping of the edge portion E3, the width L2 of the tip end of the grasping tongue is preferably set to a size of 5 mm or more.

Next, the width of the tongue base end edge E4 of the gripping tongue 16 (hereinafter referred to as the "grasping tongue base end width") L3 (refer to the partial enlarged view of FIG. 5) is mentioned. From the viewpoint of the tolerance error in the manufacture of the seal 10, the base end width L3 of each tongue base end edge portion E4 formed on both sides of the grasping tongue 16 is set to 1 mm The above width is better. Here, FIG. 8A is a diagram showing a sheet S1 for forming the sealing member 10, and the sealing member 10 has a style in which the base end edges E4 of the tongue are formed on both sides of the tongue 16 for gripping. FIG. 8B is a diagram showing the sheet S2 used to form the sealing member 10, and the sealing member 10 has a style in which the base end edges E4 of the tongue are not formed on both sides of the gripping tongue 16. The symbol CLp shown in FIGS. 8A and 8B indicates the design cutting line, and the symbol CLa indicates the actual cutting position. The sheets S1 and S2 are cut along the design cutting line CLp during the manufacturing process to be separated into each sealing member 10.

Fig. 8A and Fig. 8B show how each seal 10 is cut from the sheets S1 and S2 and cut along the actual cutting position CLa shifted from the design cutting line CLp. First, in the sheet S1 shown in FIG. 8A, since the tongue base end edges E4 are formed on both sides of the gripping tongue 16, even if the actual cutting position CLa is somewhat shifted from the design cutting line CLp, The width L3 of the base end of the gripping tongue is only slightly different from the design value and is not obvious, and the error of the cutting position of the sealing member 10 during the manufacturing process can be tolerated. On the other hand, in the sheet S2 shown in FIG. 8B, the tongue base end edges E4 are not formed on both sides of the gripping tongue 16, and the gripping tongue base end width L3 is zero. Therefore, when the actual cutting position CLa is shifted from the design cutting line CLp, in the seal 10 cut from the sheet S2, the shape of one end side and the other end side in the width direction of the seal 10 will be different. Significant. That is, an error in the cutting position of the sealing member 10 during the manufacturing process is not allowed, and the sealing member 10 may not be used in a product and has to be discarded. In addition, there is no disadvantage in increasing the base end width L3 of the grasping tongue at the base end edge E4 of the tongue, but it is determined in relation to the full width of the seal 10, the tip width L2 of the grasping tongue, etc. good.

Also, between the first oblique edge 162 (the second oblique edge 163 of the tongue) and the grabbing edge E3 connecting the grabbing edge E3 of the grabbing tongue 16 and the tongue base end edge E4 The formed angle (hereinafter referred to as "hypotenuse angle") θ (refer to Fig. 5) is preferably 90° or more. By setting the oblique angle θ of the grabbing tongue 16 to be 90° or more, the grabbing tongue 16 itself can be split from the easy-to-cut portion 15 (cut joint portion) as a starting point It's hard to happen. In addition, the upper limit angle of the inclination angle θ of the hypotenuse of the gripping tongue 16 can be based on the full width of the seal 10, the width L2 of the tip end of the gripping tongue, the base end width L3 of the gripping tongue, and the second separation distance Calculate appropriately the dimensions such as D2. In addition, in terms of the full width of the seal 10, the standard 20 mm is usually adopted. In this regard, the full width of the seal 10 is set to 20 mm, the tip width L2 of the grasping tongue is set to 5 mm, and the grasping tongues of the base end edges E4 of the respective tongues on both sides of the grasping tongue 16 When the base end width L3 is set to 1 mm and the second separation distance D2 is set to 2 mm, the oblique angle θ of the gripping tongue 16 is approximately 163°. That is, the oblique angle θ of the gripping tongue 16 can be set in a range from 90° to 163°. By setting it in such a range, the difficulty of breaking the gripping tongue 16 and the ease of gripping can be achieved. The balance of degrees. In addition, it is preferable to set the oblique angle θ of the gripping tongue 16 to a range of 105° or more and 163° or less. In addition, it is better to set the oblique angle θ of the gripping tongue 16 to a range of 130° or more and 140° or less (135±5° range). The difficulty of breaking and the ease of gripping of the gripping tongue 16 are The balance is better. In addition, the full width of the seal 10 is of course not limited to 20 mm.

Furthermore, according to the seal 10 of the present embodiment, the gripping tongue 16 of the first upper sealing portion 13 is formed in a non-adhesive state with respect to the lower sealing portion 11, and the gripping tongue 16 is inserted through the easy-to-cut portion 15 It is partially connected to the second upper seal portion 14 adjacent to the gripping tongue 16. Therefore, by grasping and pulling up the grasping tongue 16, the easy-to-cut portion 15 can be easily cut, and the second upper seal portion 14 and the lower seal portion 11 can be maintained in a state where An upper sealing portion 13 is easily peeled from the lower sealing portion 11.

In addition, according to the seal 10 of the present embodiment, the grasping tongue 16 of the first upper seal portion 13 is formed in a trapezoidal shape, and the second upper seal portion 14 is formed on the front end side thereof to be complementary to the grasping tongue 16 The trapezoid-shaped recess 17 makes the first oblique side 162 and the second oblique side 163 of the tongue 16 for grabbing, and the first oblique side 172 and the second oblique side of the recess 17 opposite to these The two oblique sides 173 can be connected by the easy-to-cut portion 15. Therefore, the easy-to-cut portion 15 of the first upper seal portion 13 can be extended in an oblique direction with respect to the first edge portion E1. By setting the extension direction of the easy-to-cut portion 15 in this way, the component of the tensile force that acts when the gripping tongue 16 is picked up will act in the direction of cutting the easy-to-cut portion 15, so that it can be cut appropriately The easy-to-cut portion 15 can also prevent parts other than the easy-to-cut portion 15 of the first upper sealing portion 13 from cracking, for example, in the area where the information pattern is printed on the inner surface 13b. In addition, the easy-to-cut portion 15 of the first upper seal portion 13 can also be extended in the vertical direction with respect to the first edge portion E1. By setting the extending direction of the easy-to-cut portion 15 in this way, When the tongue piece 16 is used, only the easy-to-cut portion 15 is appropriately cut.

In addition, according to the package 1 of this embodiment, since the slits 18a and 18b are provided in the upper third region 133 of the first upper sealing portion 13, the upper third region 133 and the lower sealing portion 11 of the first upper sealing portion 13 can be suppressed. The third area 113 of the lower layer can be smoothly folded in due to the rebound force of the paper caused by the lamination. In addition, the pulling force of the easy-to-cut portion 15 toward the front side of the package 1 can be alleviated, and the quality can be stabilized. In addition, the slits 18a and 18b can be formed with fine cuts that are not visible to the naked eye, thereby suppressing deterioration in the appearance quality of the package 1. In addition, the slits 18a and 18b of the upper third region 133 of the first upper sealing portion 13 are preferably provided in the vicinity of the second folding line LU2 (second edge portion E2). Moreover, as long as it is in the vicinity of the second folding line LU2 (the second edge E2), the slits 18a, 18b may be formed in the upper first region 131 of the first upper sealing portion 13, which can reduce the adhesion of the first upper sealing portion 13 to The rebound force of the paper caused by the lower sealing portion 11. Here, the separation distance (hereinafter referred to as the "third separation distance") D3 (refer to FIG. 5) from the second fold line LU2 (second edge portion E2) of the first upper seal portion 13 to the slits 18a, 18b is It is better to set it in the range of 0 mm or more and 5 mm or less.

Here, the smaller the third separation distance D3, the greater the effect of reducing the rebound force of the paper caused by the bonding of the upper third region 133 of the first upper seal portion 13 and the lower third region 113 of the lower seal portion 11 . Setting the third separation distance D3 within 5 mm can appropriately reduce the rebound force of the above-mentioned paper. In addition, when the third separation distance D3 is 0 mm, it means that the slits 18a and 18b are formed on the second fold line LU2 of the first upper seal portion 13. Here, the smaller the third separation distance D3 is, although the effect of reducing the rebound force of the paper can be increased as described above, but when the consumer grasps the gripping tongue 16 and pulls up the first upper seal portion 13, the first upper layer The sealing portion 13 may be easily broken at the positions of the slits 18a and 18b. Therefore, considering the effect of reducing the rebound force of the paper caused by the bonding between the upper third area 133 of the first upper seal portion 13 and the lower third area 113 of the lower seal portion 11, and the user pulls up the first upper seal portion In order to balance the difficulty of breaking the paper at 13 o'clock, the above-mentioned third separation distance D3 is preferably set in the range of 1.5 mm or more and 3.0 mm or less. In addition, the slits 18a and 18b may also be provided on the upper side of the package 1 (upper first region 131), or on the back side of the package 1 (upper third region 133). However, as in the present embodiment, when the gaps 18a and 18b are provided on the back side of the package 1 (the upper third region 133), the appearance of the package 1 is not easy for consumers to notice the gaps 18a and 18b. In addition, in this embodiment, the slits 18a and 18b are extended in parallel with the second folding line LU2. Therefore, the repulsive force generated when the upper third region 133 of the first upper seal portion 13 is folded in can be further appropriately alleviated ( Resilience).

In addition, according to the package 1 of this embodiment, the inner package 2 and the outer package 3 are covered and sealed with the outer film 4, and above the unsealing tape 5 provided on the outer film 4, the first part of the sealing member 10 is arranged The gripping tongue 16 of the upper seal part 13. Thereby, when the exterior film 4 is torn and unsealed, the gripping tongue 16 of the first upper seal portion 13 can be exposed to the outside, so that the gripping tongue 16 can be easily gripped. In addition, when the package 1 is not opened, since the entire package 1 is covered by the outer packaging film 4, the first upper sealing portion 13 of the sealing member 10 will not be torn off maliciously. In other words, it is possible to resist malicious behaviors such as arbitrary registration for promotional activities by those who have not properly purchased the package 1 (tobacco products) maliciously tearing off the first upper sealing portion 13 of the sealing member 10.

The preferred embodiment of the present invention has been described above, but the sealing material 10 and the package 1 of the embodiment can be variously modified, improved, combined, and so on. For example, in the above-mentioned embodiment, the shape of the gripping tongue 16 of the seal 10 is a trapezoid shape, but other shapes may be adopted. 9A to 9C show modified examples of the gripping tongue 16 of the seal 10. In the example shown in FIG. 9A, the gripping tongue 16 is not trapezoidal but has a rectangular shape. More specifically, the gripping edge E3 and the tongue base end edge E4 of the gripping tongue 16 shown in FIG. 9A are connected by vertical edges E5 that are perpendicular to these. In the example shown in FIG. 9B, the gripping tongue 16 has an arc-shaped gripping edge E3', and both ends of the gripping edge E3' are connected to the base end edge E4 of the tongue, respectively. Moreover, in the example shown in FIG. 9C, the linear grab edge part E3 and the tongue base end edge part E4 are connected via the arc-shaped arc edge part E6. In the present embodiment, the case where the lower sealing portion 11 and the upper sealing portion 12 of the sealing material 10 are made of paper will be described as an example, but the lower sealing portion 11 and the upper sealing portion 12 may be made of polymer materials. Examples of the polymer material forming the sealing member 10 include PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), and the like. In addition, the sealing material 10 may be formed of a bonding paper of the above-mentioned polymer material and paper, a bonding paper of a metal foil and paper, or the like. In addition, the adhesive (adhesive) used to bond the lower sealing portion 11 and the upper sealing portion 12 of the sealing member 10 may use, for example, an ethylene vinyl acetate copolymer (EVA) resin as the main agent. From the viewpoints of the ease of peeling of the upper sealing portion 12 from the lower sealing portion 11 and the prevention of accidental peeling, it is preferable to use an EVA resin-based glue, but it is not limited to this. In addition, in the present embodiment, a case where cigarettes are packaged in the package 1 is described as an example, but the package object is not particularly limited. For example, other packaging objects in the package 1 may be cigars, cigarillos, etc., and may also be smokeless cigarettes such as so-called snus (SNUS), electronic cigarettes, and the like.
