Description

package

The present invention relates to a package.

Various packages have been developed in consideration of the properties of the goods. For example, when the product is a tobacco product such as a filter cigarette or cigarette, a cigarette box is known as the package. Cigarette boxes include so-called hinge lid type packages and tan grid type packages, as well as packages that are pulled out by swinging the inner box housed in the outer box around the self-hinge or sliding it vertically or horizontally. There is.

Here, for example, a package shown in Patent Document 1 has been proposed as one form of the package. The package of Patent Document 1 is a hinge lid type package including a lid and a box body. The box body forms an opening in cooperation with an inner frame, and the opening is opened and closed by the lid. Further, in this package, magnets are provided on the lower back surface of the front wall of the lid and the front wall surface of the inner frame, and when the lid is closed, the pair of magnets come into contact with each other to generate a lid closing attractive force. Thus, in patent document 1, the closure by a lid is hold | maintained using the closing attractive force of a magnet.

International Publication No. 2014/096427

However, in order to obtain a sufficient closing attractive force with a pair of magnets as in Patent Document 1, it is necessary to secure a sufficient area occupied by the magnets. On the other hand, for example, when a magnet is provided on the sliding surface of the inner box and the outer box in a slide type package, the closing attractive force continues to act while these magnets overlap, so the opening and closing operation of the inner box smoothly The problem that it is not possible to do.

An object of the present invention is to provide a package capable of opening and closing a lid and an inner box smoothly while sufficiently closing the box.

The foregoing objective is accomplished by a package of the present invention, which package is
A box that includes a fixed wall and a movable wall that overlap each other and opens and closes, and the degree of overlap between the fixed wall and the movable wall by sliding the movable wall from the closed position to the open position with respect to the fixed wall A box that further includes an opening that is reduced, resulting in opening;
A fixed-side magnetic pole group provided on the fixed wall and having an arrangement pattern including an S pole and an N pole;
A movable-side magnetic pole group having an arrangement pattern provided on the movable wall, wherein the positions of S and N poles are reversed with respect to the arrangement pattern of the movable-side magnetic pole group at the closed position;
With
The fixed side magnetic pole group and the movable side magnetic pole group are:
When the movable wall is in a closed position with respect to the fixed wall, a closed attractive force is generated to hold the movable wall in the closed position;
When the movable wall is in a transition position between the closed position and the open position with respect to the fixed wall, the same polarity of the fixed-side magnetic pole group and the movable-side magnetic pole group according to the degree of overlap. When the magnetic poles partially overlap, a transient attractive force that is weaker than the closing attractive force is generated.

According to the package described above, when the movable wall is in the closed position with respect to the fixed wall, the arrangement patterns of the S pole and the N pole of the fixed side magnetic pole group and the movable side magnetic pole group are in a reversed relationship with each other. The magnetic poles of each other overlap. For this reason, the fixed-side magnetic pole group and the movable-side magnetic pole group attract each other by magnetic force, and this attractive force becomes a closing attractive force that holds the movable wall on the fixed wall, so that the closed state of the box can be sufficiently maintained.

On the other hand, when the movable wall is in a transition position with respect to the fixed wall, the same polarity magnetic poles of the fixed side magnetic pole group and the movable side magnetic pole group partially overlap according to the degree of overlap between the fixed wall and the movable wall. Thus, the transient attractive force is weaker than the closed attractive force. For this reason, the box can be easily opened and closed.

According to the package of the present invention, the box can be sufficiently closed and can be smoothly opened and closed.

The cigarette box 1 of the first embodiment has a double structure and includes an outer case 2 (outer box) and an inner case 3 (inner box). The outer case 2 has a rectangular parallelepiped shape and includes a front wall 10, a back wall 11, an upper wall 12 and a bottom wall 13. Further, the outer case 2 is fully opened on one side surface to form an outlet 14 through which the inner case 3 can be drawn, and the other side surface of the outer case 2 forms a side wall 15.

The side wall 15 has a push window 16 at an upper portion thereof, and the push window 16 partially exposes the inner case 3. The push window 16 can have any shape. In this embodiment, the upper end of the push window 16 has a triangular shape protruding toward the upper wall 12, and the push window 16 has a pentagonal shape as a whole.

As shown in FIG. 1, the bottom wall 13 of the outer case 2 has a self-hinge 17 at substantially the center thereof. The self hinge 17 extends across the bottom wall 13, and the bottom wall 13 is divided into a movable base 13 a positioned on the outlet 14 side by the self hinge 17 and a fixed remaining portion 13 b positioned on the side wall 15 side. Yes. The movable base 13a is not connected to either the front wall 10 or the back wall 11 of the outer case 2 and is allowed to rotate around the self hinge 17.

Further, an outer side magnetic pole group 18 (fixed side magnetic pole group) is provided in an area on the side wall 15 side on the inner surface of the front wall 10 (fixed wall, outer wall) of the outer case 2. The outer side magnetic pole group 18 has an arrangement pattern including an S pole 18a and an N pole 18b. Specifically, the S pole 18 a and the N pole 18 b of the outer side magnetic pole group 18 form a strip extending linearly along the longitudinal direction of the front wall 10. These strips are arranged so that different magnetic poles are alternately arranged along the width direction of the front wall 10 to form an array pattern of the outer side magnetic pole group 18. In the case of this embodiment, the array pattern of the outer side magnetic pole group 18 has eight strips, with the strip closest to the side wall 15 as the S pole 18a.

On the other hand, the inner case 3 has a rectangular parallelepiped shape similar to the outer case 2 and has a size that can be accommodated in the outer case 2. That is, the inner case 3 also has a front wall 20, a back wall, an upper wall 21, and a bottom wall 22, which are the front wall 10, the back wall 11, the upper wall 12, and the bottom wall of the outer case 2. 13 overlap each other.

At this time, a part of the inner side wall 24 is exposed through the push window 16 of the side wall 15 of the outer case 2.

As shown in FIG. 3, the bottom wall 22 of the inner case 3 is bonded to the outer case 2 only to the movable base 13a of the outer case 2. Therefore, the inner case 3 can be rotated around the self hinge 17 together with the movable base 13a. As a result, when the user pushes the inner side wall 24 of the inner case 3 through the push window 16 of the outer case 2, the inner case 3 rotates around the self hinge 17 together with the movable base 13a, and a part of the inner case 3, That is, a portion of the inner case 3 on the outer side wall 23 side jumps out from the outlet 14 of the outer case 2 to the side.

Also, an inner side magnetic pole group 26 (movable side magnetic pole group) is provided in an area on the inner side wall 24 side on the outer surface of the front wall 20 (movable wall, inner side wall) of the inner case. The inner side magnetic pole group 26 has an arrangement pattern including an S pole 26a and an N pole 26b. Specifically, as shown in FIG. 2, when the inner case 3 is in the closed position, the inner side magnetic pole group 26 is in relation to the S pole 18 a and the N pole 18 b of the arrangement pattern of the outer side magnetic pole group 18 of the outer case 2. The arrangement of the S pole 26a and the N pole 26b is reversed. That is, the S pole 26 a and the N pole 26 b of the inner side magnetic pole group 26 also form strips extending linearly along the longitudinal direction of the front wall 20, and these strips have different magnetic poles along the width direction of the front wall 20. They are arranged alternately. The arrangement pattern of the inner side magnetic pole group 26 has eight strips, with the strip closest to the inner side wall 24 being the N pole 26b.

Further, the inner case 3 accommodates an inner pack (not shown in FIGS. 1 to 3) in the inner case 3, and this inner pack is a bundle of filter cigarettes and cigarette smoking articles, and a packaging material that wraps the bundle. Including.

Furthermore, the upper wall 21 of the inner case 3 is opened in a region on the outer side wall 23 side, and the front wall 20 and the back wall of the inner case 3 have access notches at their upper edges. These access notches are positioned on the outer side wall 23 side of the inner case 3 and have a substantially U shape extending from the upper edge of the corresponding wall toward the bottom wall 22 of the inner case 3. Such an access notch forms an outlet 25 (opening) for goods in the inner case 3 together with the outlet 14 formed in the upper wall 21 of the inner case 3.

The inner side magnetic pole group 26 may be made of a magnetic material previously magnetized in the arrangement pattern of the S pole 26a and the N pole 26b, but preferably a magnetizable magnetic material is applied in advance to the portion of the front panel 31. Thereafter, it is obtained by forming the above-described arrangement pattern of the S pole 26a and the N pole 26b using a magnetizing device such as a magnetizing roller. At that time, by using a magnetic material that becomes an isotropic magnet, it is possible to give a degree of freedom to the magnetization direction at the time of magnetization, facilitating magnetization during the packaging process. The width of each strip of the arrangement pattern of the S pole 26a and the N pole 26b is in the range of 0.1 mm to 5 mm, preferably 0.4 mm to 0.6 mm.

Then, paste is applied to a predetermined portion on the back surface of the blank 30 described above, and the inner pack IP is placed on the back side of the front panel 31 of the blank 30. Thereafter, the blank 30, that is, the flaps and panels thereof are sequentially folded around the inner pack IP, and the inner case 3 shown in FIGS. 1 to 3 is formed. Note that the side flaps 35a, 35b, 36a, 36b forming the outer side wall 23 and the inner side wall 24 of the inner case 3 are bonded in an overlapped manner, and the front panel 31 and the rear panel 33 are bonded to the inner pack IP. The

An extension flap 48 is connected to the side edge of the outer bottom flap 47 via the self hinge 17, and the extension flap 48 extends along the remaining portion of the lower edge of the rear panel 43. The extension flap 48 is a part for forming the movable base 13a which is a part of the bottom wall 13 in the outer case 2, and the outer bottom flap 47 is for forming the fixed remaining part 13b of the bottom wall 13 of the outer case 2. Part.

Further, an intermediate bottom flap 49 is connected to a part of the lower edge of the front panel 42. The intermediate bottom flap 49 is positioned adjacent to the inner bottom flap 45. Therefore, the inner bottom flap 45 is disposed so as to be sandwiched between the outer bottom flap 47 and the intermediate bottom flap 49. Each of these

bottom flaps

45, 47, 49 has substantially the same shape and size.

Furthermore, the inner top panel 50 is connected to the upper edge of the rear panel 43, and the outer top panel 51 is connected to the upper edge of the front panel 42.

The front panel 42 is provided with the outer magnetic pole group 18 on the side panel 41 side, that is, on the left side of the front panel 42 as viewed in FIG. The outer side magnetic pole group 18 is preliminarily coated with a magnetizable magnetic material on the portion of the front panel 42, and thereafter, using the magnetizing device such as a magnetizing roller, the arrangement of the S pole 18a and the N pole 18b described above. It is obtained by forming a pattern. The outer side magnetic pole group 18 may be made of a magnetic material magnetized in advance with the arrangement pattern of the S pole 18a and the N pole 18b described above. Preferably, a magnetizable magnetic material is applied in advance to the portion of the front panel 42. Thereafter, it is obtained by forming the above-described arrangement pattern of the S pole 18a and the N pole 18b using a magnetizing device such as a magnetizing roller. At that time, by using a magnetic material that becomes an isotropic magnet, it is possible to give a degree of freedom to the magnetization direction at the time of magnetization, facilitating magnetization during the packaging process. The width of each strip of the arrangement pattern of the S pole 18a and the N pole 18b is in the range of 0.1 mm to 5 mm, preferably 0.4 mm to 0.6 mm. By setting it as such a range, the closing attractive force preferable for opening and closing operation can be generated.

Then, paste is applied to a predetermined portion on the back surface of the outer blank 40 described above, and then the outer blank 40 is folded by a predetermined folding procedure, and the outer case 2 that accommodates the inner case 3 is formed.

As described above, in the case of the cigarette box 1 of the first embodiment, the inner case 3 rotates about the self hinge 17 with respect to the outer case 2, that is, by the side swing of the inner case 3. Is opened and closed.

According to the cigarette box 1 described above, as shown in FIG. 2, when the inner case 3 is in the closed position accommodated in the outer case 2, the outlet 25 of the inner case 3 is located inside the outer case 2. Thus, the cigarette box 1 is closed. At this time, the outer side magnetic pole group 18 and the inner side magnetic pole group 26 are completely overlapped with each other so that their outer shapes coincide with each other. In this case, since the arrangement patterns of the

S poles

18a and 26a and the

N poles

18b and 26b in the

magnetic pole groups

18 and 26 are reversed, the magnetic poles having different polarities overlap each other. For this reason, the outer side magnetic pole group 18 and the inner side magnetic pole group 26 are attracted to each other by a magnetic force, and this attractive force becomes a closing attractive force for holding the inner case 3 in the outer case 2.

On the other hand, as shown in FIG. 3, when the inner case 3 is in the open position where it protrudes from the outer case 2, the outlet 25 of the inner case 3 is positioned outside the outer case 2, so that the cigarette box 1 is opened. When the cigarette box 1 is in the open state, the user can take out the smoking article from the inner pack through the outlet 25 and smoke the removed smoking article.

At this time, the outer side magnetic pole group 18 and the inner side magnetic pole group 26 are in a positional relationship crossing each other by the rotation of the inner case 3, and the degree of overlapping of these

magnetic pole groups

18 and 26 changes. Specifically, as the degree of opening of the inner case 3 increases with respect to the outer case 2 and the degree of overlap between the front wall 10 of the outer case 2 and the front wall 20 of the inner case 3 decreases, The degree of overlap between the magnetic pole group 18 and the inner side magnetic pole group 26 also decreases. On the other hand, the region where the outer side magnetic pole group 18 and the inner side magnetic pole group 26 overlap has a portion where magnetic poles of different polarities overlap to generate attractive force and a portion where magnetic poles of the same polarity overlap to generate repulsive force. . As a result, the attractive force is canceled by the repulsive force between the outer side magnetic pole group 18 and the inner side magnetic pole group 26, so that the inner case 3 is in a transient position between the closed position and the open position with respect to the outer case 2. The outer side magnetic pole group 18 and the inner side magnetic pole group 26 cooperate with each other to generate a transient attractive force that is weaker than the closing attractive force. The transition position does not include a closed position (fully closed) where the inner case 3 is completely accommodated in the outer case 2, but includes an open position (fully opened) where the inner case 3 is pulled out to the limit.

From the open state of the cigarette box 1 shown in FIG. 3, until the inner case 3 is pushed into the outer case 2 by the user and the inner case 3 is in the transition from the open position to the closed position, The aforementioned weak transient attractive force remains. When the outer side magnetic pole group 18 and the inner side magnetic pole group 26 coincide with each other in the closed position, a closing attractive force is suddenly generated, and the closed state of the cigarette box 1 is maintained.

Here, the relationship between the opening of the cigarette box and the attractive force will be described in more detail.

First, FIG. 6 shows a cigarette box 1 'as a comparative example, and FIG. 7 shows a relationship diagram between the opening degree and the attractive force in the comparative example.

As shown in FIG. 6, in the cigarette box 1 'according to the comparative example, the inner case 3' slides in the width direction with respect to the outer case 2 'and is opened and closed. An outer side magnetic pole group 18 'is provided at the lower part of the inner surface of the front wall 10' of the outer case 2 ', and an inner side magnetic pole group 26' is provided at the lower part of the outer surface of the front wall 20 'of the inner case 3'. Is provided. The outer side magnetic pole group 18 ′ and the inner side magnetic pole group 26 ′ include four S poles 18a ′ and 26a ′ and four N poles 18b ′ and 26b ′ extending linearly in the width direction of the cigarette box 1 ′. The magnetic poles form an array pattern in which different magnetic poles are alternately arranged in the longitudinal direction of the cigarette box 1 ′. Specifically, in the case of the arrangement pattern of the outer side magnetic pole group 18 ′, four S poles 18 a ′ and four N poles 18 b ′ are alternately arranged adjacent to each other from the bottom wall 13 ′ toward the upper wall 12 ′. On the other hand, the arrangement pattern of the inner-side magnetic pole group 26 'is reversed from the arrangement pattern of the outer-side magnetic pole group 18' with the arrangement of the S pole 26a 'and the N pole 26b', and from the bottom wall 22 'to the upper wall 21'. Four N poles 26b 'and four S poles 26a' are arranged adjacent to each other.

In the cigarette box 1 ′ according to the comparative example, when the inner case 3 ′ is pulled out from the outer case 2 ′, the overlap between the front wall 10 ′ of the outer case 2 ′ and the front wall 20 ′ of the inner case 3 ′. As the degree decreases, the degree of overlap between the outer side magnetic pole group 18 'and the inner side magnetic pole group 26' decreases. However, in the region where the outer side magnetic pole group 18 ′ and the inner side magnetic pole group 26 ′ overlap, magnetic poles having different polarities overlap each other to generate an attractive force. Therefore, as shown in FIG. 7, the cigarette box 1 'according to the comparative example is an attractive force between the outer side magnetic pole group 18' and the inner side magnetic pole group 26 'in proportion to the amount of withdrawal of the inner case 3', that is, the opening degree. Increase or decrease.

On the other hand, as shown in FIG. 8, in the case of the cigarette box 1 according to the first embodiment, the outer side magnetic pole group 18 and the inner side magnetic pole group 26 intersect with each other at the transitional position from fully open to fully closed. Since it increases and decreases, the transient attractive force between the outer side magnetic pole group 18 and the inner side magnetic pole group 26 hardly increases until just before full closure, even if it does not become zero. On the other hand, when it is fully closed, the attractive force suddenly increases, and a closed attractive force consisting of 100% attractive force is generated.

As described above, the cigarette box 1 according to the first embodiment can sufficiently maintain the closed state by the above-described closing attractive force when the inner case 3 is completely closed in the outer case 2. On the other hand, if the inner case 3 is pulled out from the outer case 2 by pushing out the inner case 3 through the push window 16 or the like, the attractive force between the outer side magnetic pole group 18 and the inner side magnetic pole group 26 is closed. Since the transient attractive force is greatly reduced from the attractive force, the inner case 3 can be smoothly pulled out and pushed in, and the cigarette box 1 can be easily opened and closed.

Next, FIG. 9 shows a front view of a cigarette box 61 as a package according to the second embodiment, and the second embodiment will be described with reference to FIG.

As shown in FIG. 9, the cigarette box 61 of the second embodiment has a double structure and includes an outer case 62 (outer box) and an inner case 63 (inner box). The cigarette box 61 opens and closes when the inner case 63 slides in the width direction with respect to the outer case 62. The cigarette box 61 includes a front wall 70 (fixed wall and outer wall) of the outer case 62, a back wall, an upper wall 72, an outlet 74, a side wall 75, a push window, and a front wall 80 (movable wall) of the inner case 63. , Inner wall), back wall, upper wall 81, outer side wall 83, inner side wall 84, and outlet 85 are the same as the cigarette box 1 of the first embodiment, and detailed description thereof is omitted.

On the other hand, in the cigarette box 61 of the second embodiment, the

bottom walls

73 and 82 of the outer case 62 and the inner case 63 are different from the

bottom walls

13 and 22 of the first embodiment. In the second embodiment, the bottom wall 73 of the outer case 62 and the bottom wall 82 of the inner case 63 are both flat surfaces and are slidably in contact with each other.

Further, an outer side magnetic pole group 78 (fixed side magnetic pole group) is provided in the lower region on the inner surface of the front wall 70 of the outer case 62. On the other hand, an inner side magnetic pole group 86 is provided in the lower region on the outer surface of the front wall 80 of the inner case 63. Each of the

magnetic pole groups

78 and 86 has an arrangement pattern including

S poles

78a and 86b and

N poles

78a and 86b. In these arrangement patterns, the

S poles

78a and 86b and the

N poles

78a and 86b extend in the width direction of the

front walls

70 and 80 to form a downward convex arc-shaped strip. These strips are arranged so that different magnetic poles are alternately arranged along the longitudinal direction of the

front walls

70, 80, and form an array pattern of the respective

magnetic pole groups

78, 86. When the inner case 63 is in the closed position, the inner side magnetic pole group 86 has an arrangement of the S pole 86a and the N pole 86b with respect to the arrangement of the S pole 78a and the N pole 78b in the arrangement pattern of the outer side magnetic pole group 78. It has an inverted sequence pattern. In the case of this embodiment, the arrangement pattern of the outer side magnetic pole group 78 has the strip on the bottom wall 73 side as the S pole 78a, and the arrangement pattern of the inner side magnetic pole group 86 has the strip on the bottom wall 82 side as the N pole 86b. . Each of the

magnetic pole groups

78 and 86 has six strips. Note that there are slight gaps between the

N poles

78a and 86a and the

S poles

78b and 86b of the

magnetic pole groups

78 and 86, respectively.

As described above, in the case of the cigarette box 61 of the second embodiment, the cigarette box 61 is opened and closed by the inner case 63 sliding in the width direction with respect to the outer case 62, that is, by the side slide of the inner case 63. .

According to the cigarette box 61 described above, when the inner case 63 is in the closed position accommodated in the outer case 62, the outlet 85 of the inner case 63 is positioned inside the outer case 2. Is closed. At this time, the outer side magnetic pole group 78 and the inner side magnetic pole group 86 are completely overlapped so that the outer shapes thereof coincide. In this case, since the arrangement patterns of the

S poles

78a and 86a and the

N poles

78b and 86b in the

magnetic pole groups

78 and 86 are reversed, the magnetic poles having different polarities overlap each other. For this reason, the outer side magnetic pole group 78 and the inner side magnetic pole group 86 are attracted by a magnetic force over the entire area, and this attractive force becomes a closing attractive force for holding the inner case 63 in the outer case 62.

On the other hand, as shown in FIG. 9, when the inner case 63 is in the open position protruding from the outer case 62, the outlet 85 of the inner case 63 is positioned outside the outer case 2, so that the cigarette box 61 is opened. When the cigarette box 61 is in the open state, the user can take out the smoking article from the inner pack through the outlet 85 and smoke the taken out smoking article.

At this time, the outer-side magnetic pole group 78 and the inner-side magnetic pole group 86 are in a crossed positional relationship because the

S poles

78a and 86a and the

N poles

78b and 86b form arcuate curves, respectively. The overlapping degree of 78 and 86 changes. Specifically, as the degree of opening of the inner case 63 with respect to the outer case 62 increases and the degree of overlap between the front wall 70 of the outer case 62 and the front wall 80 of the inner case 63 decreases, the outer side increases. The degree of overlap between the magnetic pole group 78 and the inner side magnetic pole group 86 also decreases. On the other hand, the region where the outer side magnetic pole group 78 and the inner side magnetic pole group 86 overlap has a portion where magnetic poles of different polarities overlap to generate attractive force and a portion where magnetic poles of the same polarity overlap to generate repulsive force. . Thereby, the attractive force between the outer side magnetic pole group 78 and the inner side magnetic pole group 86 is canceled by the repulsive force, so that the inner case 63 is in a transition position between the closed position and the open position with respect to the outer case 62. In some cases, the outer side magnetic pole group 78 and the inner side magnetic pole group 86 cooperate with each other, resulting in a transient attractive force that is weaker than the closing attractive force.

From the open state of the cigarette box 61 shown in FIG. 9 until the inner case 63 is pushed into the outer case 62 by the user and the inner case 63 is in the fully closed position during the transition from the open position to the closed position. The aforementioned weak transient attractive force remains. When the outer side magnetic pole group 18 and the inner side magnetic pole group 26 coincide with each other in the closed position, a closing attractive force is suddenly generated, and the closed state of the cigarette box 1 is maintained.

In this way, the cigarette box 61 according to the second embodiment is also in the closed state by the above-described closing attraction when the inner case 63 is completely stored in the outer case 62, as in the first embodiment. Sufficiently maintain. On the other hand, if the inner case 63 is pulled out of the outer case 62 by pushing out the inner case 63 through the push window, the attractive force between the outer side magnetic pole group 78 and the inner side magnetic pole group 86 is the closing attractive force. Since the transient attractive force is greatly reduced, the inner case 63 can be smoothly pulled out and pushed in, and the cigarette box 61 can be easily opened and closed.

Next, FIG. 10 shows a front view of a cigarette box as a package according to the third embodiment, and the third embodiment will be described with reference to FIG.

As shown in FIG. 10, the cigarette box 91 of the third embodiment has a double structure, like the cigarette box 61 of the second embodiment, and has an outer case 92 (outer box) and an inner case 93 (inner box). Is included. The cigarette box 91 opens and closes when the inner case 93 slides in the width direction with respect to the outer case 92. The cigarette box 91 includes a front wall 100 (fixed wall, outer wall) of the outer case 92, a back wall, an upper wall 102, a bottom wall 103, an outlet 104, a side wall 105, a push window, and a front wall of the inner case 93. 110 (movable wall, inner side wall), back wall, upper wall 111, bottom wall 112, outer side wall 113, inner side wall 114, and outlet 115 are the same as the cigarette box 61 of the second embodiment, and the detailed explanation is as follows. Omitted.

In the cigarette box 91 of the third embodiment, an outer side magnetic pole group 108 is provided in a lower region of the inner surface of the front wall 100 of the outer case 92, and an inner side magnetic pole group 116 is provided in a lower region of the outer surface of the front wall 110 of the inner case 93. Is provided. Each of the

magnetic pole groups

108 and 116 has an arrangement pattern including

S poles

108a and 116b and

N poles

108b and 116b. In these arrangement patterns, the

S poles

108 a and 116 b and the

N poles

108 b and 116 b form a linear strip extending along the longitudinal direction of the

front walls

100 and 110. These strips are arranged so that different magnetic poles are alternately arranged along the width direction of the

front walls

100 and 110, and form an array pattern of the

magnetic pole groups

108 and 116, respectively. The inner side magnetic pole group 116 has an arrangement pattern in which the arrangement of the S pole 86a and the N pole 86b is reversed with respect to the arrangement of the S pole 78a and the N pole 78b of the arrangement pattern of the outer side magnetic pole group 78. In this embodiment, the outer side magnetic pole group 108 has an arrangement pattern in which the strip on the side wall 105 side is the S pole 108a, and the inner side magnetic pole group 116 has the strip on the outer side wall 113 side the S pole 116a. Each

magnetic pole group

108 and 116 has 12 strips.

As described above, in the case of the cigarette box 91 of the third embodiment, similarly to the cigarette box 61 of the second embodiment, the inner case 93 slides in the width direction with respect to the outer case 92, that is, the inner case 93. The cigarette box 91 is opened and closed by the side slide.

According to the cigarette box 91 described above, when the inner case 93 is in the closed position accommodated in the outer case 92, the outlet 115 of the inner case 93 is positioned inside the outer case 92. Is closed. At this time, the outer side magnetic pole group 108 and the inner side magnetic pole group 116 overlap with each other so that their outer shapes match. In this case, since the arrangement patterns of the

S poles

108a and 116a and the

N poles

108b and 116b in the respective

magnetic pole groups

108 and 116 are reversed, the magnetic poles having different polarities overlap each other. For this reason, the outer side magnetic pole group 78 and the inner side magnetic pole group 86 are attracted by a magnetic force over the entire area, and this attractive force becomes a closing attractive force for holding the inner case 93 in the outer case 92.

On the other hand, as shown in FIG. 10, when the inner case 93 is in the open position where it protrudes from the outer case 92, the outlet 115 of the inner case 93 is positioned outside the outer case 92, so that the cigarette box 91 is opened. When the cigarette box 91 is in the open state, the user can take out the smoking article from the inner pack through the outlet 115 and smoke the removed smoking article.

At this time, the opening degree of the inner case 93 with respect to the outer case 92 increases, and the degree of overlap between the front wall 100 of the outer case 92 and the front wall 110 of the inner case 93 decreases, The degree of overlap between the magnetic pole group 108 and the inner side magnetic pole group 116 also decreases. On the other hand, the region where the outer side magnetic pole group 108 and the inner side magnetic pole group 116 overlap is a portion where magnetic poles of different polarities overlap each other and generate an attractive force step by step according to the opening of the inner case 93 with respect to the outer case 92. The magnetic poles of the same polarity overlap each other to generate a repulsive force.

Specifically, FIG. 11 shows a diagram for explaining the positional relationship between the outer side magnetic pole group 108 and the inner side magnetic pole group 116 in accordance with the opening degree of the outer case 92 of the third embodiment. In FIG. 11, the outer side magnetic pole group 108 is shown on the lower side and the inner side magnetic pole group 116 is shown on the upper side, and the positional relationship between the

S poles

108a and 116a and the

N poles

108b and 116b is conceptually shown.

When the inner case 93 is fully enclosed in the outer case 92 as in the state of FIG. 11A, the magnetic poles having different polarities in the entire region of the outer side magnetic pole group 108 and the inner side magnetic pole group 116 Overlapping creates a 100% closure attraction.

When the inner case 93 is slightly pulled out from the outer case 92, the polarities of different polarities are obtained in the region where the outer side magnetic pole group 108 and the inner side magnetic pole group 116 overlap as shown in FIG. A portion where the magnetic poles overlap to generate attractive force and a portion where the same polarity magnetic poles overlap to generate repulsive force are generated. As a result, the attractive force between the outer side magnetic pole group 108 and the inner side magnetic pole group 116 is canceled by the repulsive force, so that the outer side magnetic pole group 18 and the inner side magnetic pole group 26 cooperate with each other, and more than the closing attractive force. Generate weak transient attraction.

Further, when the inner case 93 is pulled out from the outer case 92, the magnetic poles having different polarities overlap each other in the overlapping region of the outer side magnetic pole group 108 and the inner side magnetic pole group 116 as shown in the state (c) of FIG. At this time, since the two strips located at one end of the outer side magnetic pole group 108 and the inner side magnetic pole group 116 do not overlap each other, it is weaker than the closing attractive force in the state (a), but there is no portion where repulsive force is generated. b) A transient attractive force stronger than the state (hereinafter, this transient attractive force is referred to as a holding attractive force) is generated.

As described above, in the cigarette box 91 of the third embodiment, a holding attractive force is generated each time the inner case 93 is pulled out by a certain amount corresponding to two strips, and the opening and closing can be performed in stages. The holding attractive force becomes weaker as the pulling amount of the inner case 93 becomes larger, because the degree of overlap between the outer side magnetic pole group 108 and the inner side magnetic pole group 116 decreases.

In this way, in the cigarette box 91 according to the third embodiment, as in the first and second embodiments, when the inner case 93 is completely stored in the outer case 92, the cigarette box 91 is closed by the closing attractive force. Can be maintained sufficiently. On the other hand, if the inner case 93 is pulled out of the outer case 92 by pushing out the inner case 93 through the push window or the like, the attractive force between the outer side magnetic pole group 108 and the inner side magnetic pole group 106 is the closing attractive force. The transient attractive force is further reduced, and the inner case 63 can be smoothly pulled out and pushed in, while the predetermined pulling amount can be held by the holding attractive force.

Next, FIG. 12 shows a perspective view of a cigarette box 121 as a package according to the fourth embodiment. The fourth embodiment will be described with reference to FIG.

As shown in FIG. 12, the cigarette box 121 of the fourth embodiment is a hinge lid type package. The cigarette box 121 includes a box main body 122 having an opening 122a at the upper end, an inner frame 123 extending upward from the box main body 122 to form an outlet 123a (opening) at the upper end, and a hinge 124 to the cigarette box 120. And a lid 125 connected to each other. The inner pack IP is accommodated in the cigarette box 121.

Specifically, the lid 125 is hinged to the rear edge of the opening 122a in the box body 122, covers the cover 125 while including the outlet 123a of the inner frame 123 in the closed position (not shown), and opens the outlet 123a in the open position shown in FIG. . Therefore, the inner frame 123 is not exposed to the outside when the lid 125 is in the closed position, and is exposed including the outlet 123a when the lid 125 is in the open position.

The box body 122 has a front wall 130, a back wall 131, a bottom wall 132, and

side walls

133 and 134. The inner frame 123 has a front wall 140 and side walls 141 and 142 (fixed walls). The lid 125 includes a front wall 150, a back wall 151, an upper wall 152, and side walls 153 and 154 (movable walls).

Also, an inner side magnetic pole group 143 (fixed side magnetic pole group) is provided on the outer surface of one side wall 142 of the inner frame 123 in the upper region. The inner side magnetic pole group 143 has an arrangement pattern including an S pole 143a and an N pole 143b. Specifically, the S pole 143a and the N pole 143b of the inner side magnetic pole group 143 form strips that extend linearly along the depth direction of the side wall 142, and these strips alternate with different magnetic poles along the vertical direction of the side wall 142. It is arranged to line up. In this example, in this example, the arrangement pattern of the inner-side magnetic pole group 142 has four strips, with the uppermost strip as the S-pole 143a.

Also, an outer side magnetic pole group 155 (movable side magnetic pole group) is provided on the inner surface of one side wall 154 of the lid 125 in the upper region. The outer side magnetic pole group 155 also has an arrangement pattern including an S pole 155a and an N pole 155b. Specifically, when the lid 125 is in a closed position (not shown), the outer side magnetic pole group 155 is arranged with the S pole 155a and the N pole 155b with respect to the S pole 143a and the N pole 143b in the arrangement pattern of the inner side magnetic pole group 143. Has an inverted sequence pattern. In other words, the S pole 155a and the N pole 155b of the outer side magnetic pole group 155 also form strips extending linearly along the depth direction of the side wall 154, and these strips alternate with different magnetic poles along the vertical direction of the side wall 154. They are arranged side by side. In the case of this embodiment, the arrangement pattern of the outer side magnetic pole group 155 has four strips, with the strip on the uppermost wall 152 side being the N pole 143b.

In the case of the cigarette box 121 of the fourth embodiment, the cigarette box 121 is opened and closed by rotating the lid 125 around the hinge 124 with respect to the box body 122.

That is, in the cigarette box 121 of the fourth embodiment, when the lid 125 is in the closed position, the outlet 123a of the inner frame 123 is positioned inside the lid 125, and thereby the cigarette box 121 is closed. At this time, the inner side magnetic pole group 143 and the outer side magnetic pole group 155 are completely overlapped so that the outer shapes thereof coincide with each other. In this case, since the arrangement patterns of the

S poles

143a and 155a and the

N poles

143b and 155b in the respective

magnetic pole groups

143 and 155 are reversed, the magnetic poles having different polarities overlap each other. For this reason, the inner side magnetic pole group 143 and the outer side magnetic pole group 155 are attracted by a magnetic force over the entire area, and this attractive force becomes a closing attractive force for holding the lid 125 on the inner frame 123.

On the other hand, as shown in FIG. 12, when the lid 125 is in the open position, the outlet 123a of the inner frame 123 is opened, thereby opening the cigarette box 121. When the cigarette box 121 is in the open state, the user can take out the smoking article from the inner pack IP through the outlet 123a and smoke the taken out smoking article.

In the process of opening and closing the lid 125, the inner side magnetic pole group 143 and the outer side magnetic pole group 155 are in a crossed positional relationship as the lid 125 rotates around the hinge 124, and the lid 125 has a position relative to the inner frame 123. As the degree of opening increases and the degree of overlap between the side wall 142 of the inner frame 123 and the side wall 154 of the lid 125 decreases, the degree of overlap between the inner side magnetic pole group 143 and the outer side magnetic pole group 155 also decreases. To do. And in the area | region where the inner side magnetic pole group 143 and the outer side magnetic pole group 155 overlap, it has a part which magnetic poles of different polarities overlap and produce attractive force, and a part where magnetic poles of the same polarity overlap and produce repulsive force. Thereby, the attractive force between the inner side magnetic pole group 143 and the outer side magnetic pole group 155 is canceled by the repulsive force, and when the lid 125 is in a transitional position between the closed position and the open position with respect to the inner frame 123, The transient attractive force is weaker than the closed attractive force.

From the open state of the cigarette box 121 shown in FIG. 12, the above-mentioned weak transient attractive force remains until the lid 125 is completely closed during the transition from the open position to the closed position by being pushed by the user. . When the inner side magnetic pole group 143 and the outer side magnetic pole group 155 coincide with each other at the closed position, a closing attractive force is suddenly generated, and the closed state of the cigarette box 121 is maintained.

Thus, in the cigarette box 121 according to the fourth embodiment, when the lid 125 is fully closed, the closed state can be sufficiently maintained by the closing attractive force. On the other hand, if the lid 125 is opened as much as possible, the attractive force between the inner side magnetic pole group 143 and the outer side magnetic pole group 155 becomes a transient attractive force that is greatly reduced from the closing attractive force, so that the lid 125 is smoothly opened and closed. The cigarette box 121 can be easily opened and closed.

The present invention is not limited to the above embodiment, and various modifications are possible. For example, referring to FIG. 13, there is shown a first modified example having a shape of a magnetic pole group different from that of the above embodiment.

The cigarette box 161 of the first modification shown in FIG. 14 is the same as the cigarette box 1 of the first embodiment except for the outer side magnetic pole group 162 and the inner side magnetic pole group 163, and is the same as the cigarette 1 of the first embodiment. Elements are given the same reference numerals and description thereof is omitted.

This first modification differs from the first embodiment in that the outer side magnetic pole group 162 and the inner side magnetic pole group 163 are circular.

Specifically, four outer side magnetic pole groups 162 are provided on the outer surface of the front wall 10 (fixed wall, outer wall) of the outer case 2. Four outer side magnetic pole groups 162 are arranged side by side in the longitudinal direction in the region on the side wall 15 side of the front wall 10. Each outer-side magnetic pole group 162 has an arrangement pattern in which S poles 162a and N poles 162b are alternately arranged concentrically. In the case of this first modification, the arrangement pattern of the outer side magnetic pole group 162 has four concentric circles with the center circle as the S pole 162a.

Further, four inner side magnetic pole groups 163 are provided on the inner surface of the front wall 20 (movable wall, inner wall) of the inner case 3. Four inner side magnetic pole groups 163 are arranged in the longitudinal direction in the region on the side wall 15 side of the front wall 20. Each inner-side magnetic pole group 163 has an arrangement pattern in which S poles 163a and N poles 163b are alternately arranged concentrically. The S pole 163a and the N pole 163b of this arrangement pattern have a reversed value with respect to the arrangement of the S pole 162a and the N pole 162b of the outer side magnetic pole group 162. In the case of the first modification, the arrangement pattern of the inner side magnetic pole group 163 has four concentric circles with the center circle as the N pole 163b.

Also in the cigarette box 161 of the first modified example, as in the first embodiment, when the inner case 3 is in the closed position with respect to the outer case 2, it is between the outer side magnetic pole group 162 and the inner side magnetic pole group 163. A closing attractive force is generated to hold the inner case 3 in the closed position. When the inner case 3 is in a transition position between the closed position and the open position, the outer side magnetic pole group 162 and the inner magnetic pole group 162 are connected to the inner case 3 according to the degree of overlap between the front wall 20 of the inner case 3 and the front wall 10 of the outer case. Within the region where the side magnetic pole group 163 overlaps, magnetic poles having the same polarity partially overlap to generate a transient attractive force that is weaker than the closing attractive force. Thereby, the same effect as the first embodiment can be obtained.

As described above, the shape and number of magnetic pole groups are not particularly limited. For example, the S pole and the N pole may be wave-shaped strips as other shapes. Also, for example, in the case of a cigarette box in which the inner case rotates about the self hinge with respect to the outer case as in the first embodiment, the arrangement pattern of each magnetic pole group is shown as follows. The strip may extend along the longitudinal direction of the front wall. Furthermore, the S pole and the N pole of the magnetic pole group do not necessarily need to be in contact with each other, and there may be a gap between the N pole and the S pole of the magnetic pole group as in the second embodiment.

Also, the arrangement of the magnetic pole group is not limited to the arrangement of the above-described embodiments and modifications. For example, the circular magnetic pole group in the first modification may be randomly arranged on the wall. In the above-described embodiments and modifications, the front wall of each of the outer case and the inner case, and one side wall of each of the inner frame and the lid are one fixed wall and one movable wall on which the magnetic pole group is provided. The position and number of walls and movable walls are not limited to this. For example, the magnetic pole group may be provided not only on the front wall of the outer case and the inner case of the first embodiment but also on the back wall of each case.

Further, in addition to the magnetic pole group that generates the closing attractive force in the cigarette box as in the above-described embodiments and modifications, a magnetic pole group may be provided as a stopper that holds the open state of the cigarette box. For example, FIG. 14 shows a front view of a cigarette box 161 of a second modified example in which a second magnetic pole group as a stopper is added to the cigarette box 61 of the second embodiment. In FIG. 14, the same elements as those of the second embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the cigarette box 171 of the second modified example, the second outer side magnetic pole group 172 is provided on the inner surface of the front wall 70 of the outer case 62. Specifically, the second outer-side magnetic pole group 172 is a region on the outlet 74 side of the front wall 70 and is provided at the center in the longitudinal direction. The second outer side magnetic pole group 172 has a circular shape, and has an arrangement pattern in which the S pole 172a and the N pole 172b are arranged concentrically. In the case of this second modification, the arrangement pattern of the second outer side magnetic pole group 172 has two concentric circles with the center circle as the S pole 172a.

On the other hand, a second inner side magnetic pole group 173 is provided on the outer surface of the front wall 80 of the inner case 63. Specifically, the second inner side magnetic pole group 173 is a region on the inner side wall 84 side of the front wall 80 and is provided in the central portion in the longitudinal direction. The second inner side magnetic pole group 173 also has a circular shape, and has an arrangement pattern in which the S pole 173a and the N pole 173b are arranged concentrically. The S pole 173a and the N pole 173b of this arrangement pattern are arranged in an inverted manner with respect to the arrangement of the S pole 172a and the N pole 172b of the second outer side magnetic pole group 172. The arrangement pattern of the second outer side magnetic pole group 173 has two concentric circles with the center circle as the N pole 173b.

The cigarette box 171 of the second modified example completely overlaps so that the outer shapes of the second outer side magnetic pole group 172 and the second inner side magnetic pole group 173 coincide when the inner case 63 is pulled out to the full open position. As a result, a holding attractive force is generated that holds the cigarette box 171 in an open state between the second outer side magnetic pole group 172 and the second inner side magnetic pole group 173. On the other hand, if the inner case 63 is pushed in even a little from there, the holding attractive force is weakened rapidly, and the inner case 63 can be pushed in smoothly.
