Side open box

The present invention relates to a side open type package.

In the past, as a package (package) for accommodating a cigarette or the like, a flexible package and a rigid package (box type package) are well known. As one form of the rigid package, the side open type package is generally known (for example, refer to Patent Document 1). In general, the side open type package is rotatably coupled to the inner box and the outer cover by a hinge extending in a downward direction along the side wall of the inner box, wherein the inner box is for accommodating the cigarette bundle and the outer cover It is possible to switch the outlet of the cigarette formed in the inner box. Moreover, in general, the package of a cigarette is a structure which accommodates the inner package which consists of bundles of the inner-packages in the accommodating part.

However, in the case of manufacturing a side opening type box type package, for the purpose of protecting cigarettes (cigarettes) and preventing the loosening of tobacco yarns, there is a case where a flap covering the portion is provided at the open end of the upper portion formed in the inner box. In many cases, such a flap is formed along the width direction of the inner casing so that the front portion of the open end of the inner box is retained as a cigarette take-out port and covers the rear portion.

Patent Document 2: JP-A-2010-13118

However, in the conventional side open type package, the actual situation is that when the outer cover is closed, the cigarette bundle and the contents or the flap itself which are folded by the bundle of the cigarette bundle are easily attached. The cover is disturbed. That is, when the outer cover is closed, the upper wall portion covering the outer cover side of the take-out port is overlapped with at least a portion of the upper surface of the flap, so that the outer cover is closed. The upper wall portion on the outer cover side easily collides with the flap on the inner box side or the object stored in the inner box, and there is a problem of damaging the members and articles. In particular, when the contained article contains the cigarette and the inner packaging material of the cigarette, the end portion of the inner packaging material which is folded back due to the collision with the upper wall portion is sandwiched between the upper wall portion and the flap, and is repeated. When the switch of the cover is performed, it becomes a cause of damage of the inner package, and the appearance (in appearance) of the package may be damaged (deteriorated).

The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique for suppressing interference between an outer cover and a stored object, a flap, and the like when the outer cover is closed in a side open type package. The contents and the flaps are damaged, or the appearance of the package is damaged.

In order to solve the above problems, the present invention provides a side opening type package in which a flap of an inner box is connected (joined) so as to be connected to a front wall in a connection section of at least a part of a width direction of the inner box.

In detail, the side open type package of the present invention has an inner box. The upper end has an open end and has a substantially cubic shape; and a flap that covers a portion of the open end as a receiving opening of the stored object while covering the retained portion; and an outer cover that transmits through the inner box a hinge formed by one of the side walls of the width direction is rotatably coupled to the inner casing and has at least an upper wall portion covering the outlet when closed; and the flap is attached to the width direction of the inner casing At least a portion of the connection section is connected to the front wall of the inner casing.

The side open type packaging box (lateral opening type packaging box) is extended in a direction orthogonal to the plane direction of the hinge and the inner box flap. On the other hand, when the outer cover is closed, an upper wall portion for covering the outlet of the inner casing is formed on the outer cover side. The upper wall portion is disposed in parallel with the flap of the inner box, and is slowly approached to the flap when the outer lid is closed. The upper wall portion of the outer cover is partially overlapped with the flap of the inner box and slides on one side, and finally covers the entire take-out opening to complete the closing operation of the outer cover.

In contrast, in the side open type package of the present invention, the connection section of the section of at least a part of the width direction of the inner box is connected to the front wall of the inner box, so that when the outer cover is closed, The upper wall portion of the outer cover will sneak into the lower side of the flap (on the side of the storage space of the object), and it is not easy to collide with the flap. Therefore, the flap is prevented from being bent or broken. Further, in the above-described connection section, since the upper portion of the object stored in the inner casing is covered by the flap, the upper wall portion on the outer lid side is prevented from interfering (collision and contact) with the object to be stored. In this way, it is possible to provide a side opening type package which can suppress damage to the object and the flap and damage the appearance of the package.

Here, the side open type package is opened and closed with a hinge extending in the height (up and down) direction of the package. Therefore, when closing the cover, the more In the region near the hinge, the upper wall portion of the outer cover approaches the object stored in the inner box at a steep angle, so that the members tend to easily interfere with the article. Therefore, in the present invention, the flap may be connected from a hinge side end portion of the inner box to a position intermediate the width direction of the inner box. At this time, the hinge and the proximal region are set in the width direction of the inner casing in the connection section between the front wall and the flap. According to this, since the object is covered by the flap in the hinge and the proximal region of the inner box, even if the upper wall portion approaches the object to be stored at a steep angle, the upper wall portion does not collide with the object to be stored, and can be more appropriately Suppress damage to the contents.

Further, the flap may be folded to the opening end side with a folding line formed along the upper end edge while extending from the upper end edge of the front wall in the connecting section. According to this, the flaps integrally connected from the front wall side are disposed so as to surround the open end side throughout the connection section of the inner casing. According to this, the joint portion between the flap and the front wall of the connection portion of the inner casing does not form a gap, a recess or the like which is caught at the front end portion of the upper wall portion, and the upper wall of the outer cover can be more reliably suppressed. The deformation of the part causes the flap to bend or break.

Furthermore, the predetermined hinge proximal region including the hinge side end portion of the aforementioned upper wall portion can be deeper than the predetermined hinge distal region of the hinge proximal region further from the far side of the hinge. It is constructed in a smaller size. According to this configuration, when the outer lid is closed, the depth dimension of the proximal portion of the hinge of the object to be stored in the inner box at a steep angle is set to be relatively smaller than the distal region of the hinge. Compared with the case where the depth dimension of the proximal region of the hinge is set to be equal to the distal region of the hinge, the interference between the proximal region of the hinge portion of the upper wall portion and the flap of the inner casing and the object to be stored becomes less likely to occur. Therefore, the damage of the flaps of the inner box and the objects to be stored can be appropriately avoided, and the members and articles can be appropriately prevented. The appearance is damaged. Further, the distal region of the hinge of the upper wall portion is less likely to interfere with the interference between the upper wall portion and the flap and the object to be stored when the outer lid is closed than the proximal region of the hinge. Therefore, with respect to the distal region of the hinge of the upper wall portion, it is less likely to exhibit the above-mentioned lack of interference even if the depth dimension is increased compared to the proximal region of the hinge. Then, in the distal region of the hinge of the upper wall portion, by setting the depth dimension to be larger than the proximal region of the hinge, the depth opening of the outlet formed in the region corresponding to the distal region of the hinge can be sufficiently ensured width. In this way, it is helpful to improve the ease of taking out the stored objects through the take-out.

Furthermore, as described above, the depth dimension of the proximal region of the hinge is set to be smaller than the distal region of the hinge of the upper wall portion, and the proximal region of the hinge of the upper wall portion may be formed closer to the end portion of the hinge side. The depth dimension becomes smaller. According to this, in the proximal region of the hinge of the upper wall portion, by slowly decreasing the depth dimension as approaching the hinge side end portion, the hinge proximal region of the upper wall portion and the flap of the inner box can be appropriately avoided and Interference with the contents. Further, according to this configuration, since the free end side edge portion of the hinge proximal region of the upper wall portion is formed as an inclined edge portion, a steep drop is not formed at the free end side edge portion in the middle of the hinge proximal region. As a result, there is an advantage in that when the outer lid is closed, the free end side edge portion of the upper wall portion is less likely to be caught in the flap and the object to be stored. On the other hand, there is an advantage in that in the proximal region of the hinge, since the depth dimension is gradually increased as moving away from the hinge side end portion, the depth of the outlet from the region away from the hinge can be sufficiently ensured. Opening width. Therefore, in the range in which the interference between the flap of the inner box and the object to be stored can be avoided, the ease of taking out the object to be taken through the take-out port can be appropriately improved.

Further, the depth dimension of the hinge side end portion of the upper wall portion may be substantially zero. At this point, the proximal region of the hinge of the upper wall is followed by The proximal region of the hinge is slowly reduced in depth and is constructed such that the depth dimension is zero in the hinge-side end. According to this, it is possible to more appropriately avoid the interference between the proximal region of the hinge of the upper wall portion and the flap of the inner box and the object to be accommodated.

Furthermore, in the invention, the hinge may be formed along an edge portion forming a boundary between the front wall of the inner casing and one of the side walls. Thus, by forming the hinge along the edge between the front wall and the side wall of the inner casing, the side end of the front wall portion covering the front wall of the inner casing can be directly joined to the inner casing by the hinge when the outer cover is closed. According to this configuration, compared with the case where the hinge is formed along the edge between the rear wall and the side wall of the inner box, when the outer cover is closed, the upper wall portion of the outer cover can be folded close to the inner box at a gentle angle. Tablets and objects. Therefore, when the outer cover is closed, the flaps of the inner box and the interference between the objects and the upper wall portion can be more appropriately prevented. Further, the outer cover is coupled to the inner casing by transmitting a hinge formed along the edge of the boundary between the front wall and the side wall of the inner casing, even if the depth dimension of the hinge side end portion of the upper wall portion is substantially In the case of zero, the side end of the front wall portion of the outer cover can be directly connected to the inner box by a hinge. As a result, the rigidity of the outer cover can be suppressed from being lowered.

Further, the side open type package of the present invention comprises: a film gauge disposed on a front wall of the inner box; and a sketch display sheet superimposed on the film sheet and displayed with a sketch of the sketch And a Slit Animation method, wherein the animation is generated by sliding the two relative to each other, and the end of the sketch display sheet is fixed to the inner box through the hinge. The front wall portion of the outer cover is configured to interlock with the opening and closing operation of the outer cover and to slide the sketch display sheet relative to the film meter. According to this, when the operator switches the cover, in conjunction with the switch operation, the sketch display sheet can be slid relative to the film meter, and a visual effect of generating a slit animation can be obtained. therefore, The box can be added value and can promote the consumer's willingness to purchase.

In addition, the object to be stored in the side open type package of the present invention is not particularly limited, and, for example, a tobacco product can be appropriately exemplified as the object to be stored. The so-called tobacco product can be exemplified by paper roll tobacco (filter cigarette, non-absorbent tobacco (no filter), cigar (cigar), cigar, mouth, smoke, chewing tobacco, electronic tobacco, etc. Of course, The side open type package of the present invention can also store items other than tobacco products such as candy, chewing gum, and the like.

Further, means for solving the problems of the present invention can be employed as much as possible in combination.

According to the present invention, there is provided a technique for suppressing interference between an outer cover and an object to be stored and a flap when the outer cover is closed, and suppressing damage of the object and the flap, thereby preventing the damage of the object and the flap. The appearance of the box was damaged.

<Embodiment>

In the embodiment of the side open package of the present invention, it will be described based on the drawings. The stored article accommodated in the package to which the present invention is applied is not limited to a specific package, and the case where the cigarette is stored in the package will be described as an example.

[Composition of the box]

Fig. 1 and Fig. 2 are perspective views of a side open type package (hereinafter simply referred to as "package") 1 according to the embodiment. 1 and 2 are oblique views of the package 1 viewed from the front side. The package 1 has a substantially cubic shape as a whole, and has an inner case 2 and an outer cover 3 that are coupled by a hinge. Fig. 1 shows a package 1 in a state in which the outer cover 3 is opened for the inner casing 2. On the other hand, Fig. 2 shows the package 1 in a state in which the outer cover 3 is closed, and the outlet 26 of the cigarette (the stored object) of the inner case 2 is exposed (opened) to the outside. Hereinafter, in the present specification, the front side of the package 1 is defined as "front" except for the case specifically mentioned, and the back side is defined as "rear".

The inner case 2 has a substantially cubic shape and is a storage case that can accommodate the inner package 6 composed of the cigarette 61 and the inner wrapping material 62. The details of the inner package 6 will be described later. The inner casing 2 has a rectangular rear wall 21, a front wall 22 disposed opposite the rear wall 21, and a pair of side walls 23A, 23B, a bottom wall 24, and the like which are connected to the side walls 23A and 23B of the rear wall 21 and the front wall 22, respectively. The open end formed at the upper portion thereof is partially blocked by the flap 25. The bottom wall 24 is coupled to each of the lower ends of the rear wall 21, the front wall 22, and the pair of side walls 23A, 23B. Here, the front wall 22 and the rear wall 21 are defined by the height and width of the inner box 2, and the pair of side walls 23A, 23B are defined by the height and depth of the inner box 2, and the bottom wall 24 is bounded by the inner box 2. Width and depth are specified. Will be determined in this manual The upper and lower (height) direction, the left and right (width) direction, and the front and rear (depth) directions of the inner box 2 are shown in Fig. 2 . As shown in the figure, the upper (lower) direction, the left and right (width) direction, and the front and rear (depth) directions of the inner casing 2 are individually orthogonal to each other.

Here, the symbol 4 is formed in a hinge forming an edge of the boundary between the side wall 23A of the inner casing 2 and the front wall 22. The hinge 4 is formed along the side wall 23A of one of the inner casings 2, and the inner casing 2 and the outer cover 3 are connected by a hinge so as to be rotatable with each other through the hinge 4. That is, the hinge 4 is disposed to extend along the height direction (up and down direction) of the inner casing 2. In the width direction (left-right direction) of the inner casing 2, the edge portion 5 which forms the boundary between the side wall 23B on which one of the hinges 4 is not formed and the front wall 22 is formed into a rounded shape (rounded corner) having a circular shape (circular shape). . Further, the other edge portion of the inner casing 2, that is, the edge portion which forms the boundary between the side wall 23A and the front wall 22, the edge portion which forms the boundary between the side wall 23A and the rear wall 21, and the edge which forms the boundary between the side wall 23B and the rear wall 21 The part is formed into a square side (square angle) having a square shape. Further, in the above-described configuration example, the edge portion 5 of the inner casing 2 is formed as a rounded edge, and the other edge portion of the inner casing 2 is formed as a square side, but the invention is not limited thereto. For example, the edge of the inner box 2 can also be made into a chamfered edge. For example, by forming the edge portion 5 forming the boundary between the side wall 23B of the inner box 2 and the front wall 22 by a rounded or chamfered edge, interference between the side wall 32 of the outer cover 3 and the edge portion 5 can be suppressed, and Close the cover 3 smoothly.

In the case of the inner case 2, the inner package 6 formed by wrapping the bundle of the cigarettes 61 with the inner wrapping material 62 is used to house (accommodate) the cigarettes 61. The inner wrapping material 62 is, for example, a sheet of aluminum vapor-deposited paper having a rectangular shape and comprising a paper substrate and a film of aluminum deposited on the surface. The film of aluminum protects the cigarette 61 from moisture, and prevents the release of fragrance from the cigarettes 61, and also maintains the shape of the bundle of cigarettes 61.

Next, the flap 25 of the inner box 2 and the take-out port 26 of the cigarette 61 will be described. The flap 25 is a member that covers the remaining portion of the open end while retaining one of the open ends of the inner box 2 as the outlet 26 of the cigarette 61 to be stored. That is, the flap 25 can be regarded as a top wall (top panel) which is disposed to face the bottom wall 24 of the inner casing 2 for taking out the outlet 26 of the cigarette 61. The flap 25 covers the rear side of the open end (portion close to the rear wall 21) when the open end is viewed from above the inner box 2. Further, the flap 25 also covers a portion of the front side of the open end (portion close to the front wall 22), and specifically, one of the ends of the position where the hinge 4 is located covers the front side of the proximal region.

Further, the upper portion of the front wall 22 and the side wall 23B of the inner casing 2 is formed with a notch recess 27 so as to span both sides. As shown in FIG. 1, the notch recessed portion 27 is formed in the upper right corner portion of the front wall 22 when the inner box 2 is viewed from the front side. Further, the notch recess 27 defines the contour (outer shape) of the outlet 26 together with the edge of the flap 25. That is, the take-out opening 26 of the inner box 2 is defined as an open area surrounded by the flap 25 and the notch recess 27. Further, the notch recessed portion 27 is not provided to span the upper portion of the front wall 22 of the inner casing 2 and the upper portion of the side wall 23B, but may be formed only in the upper portion of the front wall 22 or only in the upper portion of the side wall 23B. However, in the present embodiment, the notch recessed portion 27 of the inner casing 2 is formed so as to straddle the upper portion of the front wall 22 and the upper portion of the side wall 23B, so that the degree of exposure of the contents accommodated in the inner casing 2 is improved. As a result, the operator can take out the contained object more easily.

In addition, as shown in FIG. 1, the flap 25 is connected from the end portion on the hinge 4 side of the inner casing 2 (hereinafter, simply referred to as "hinge side end portion") to the intermediate position in the width direction of the inner casing 2. The front wall 22 of the inner box 2 is joined (connected). Hereinafter, the section between the flap 25 to which the inner box 2 is attached and the front wall 22 is referred to as a "connection section". This is indicated by the symbol Zc in the figure. The upper end of the front wall 22 and the front end of the flap 25 are connected to each other through the connecting section Zc, and are connected to each other (joined), and the connecting edge portion 7 belonging to the common edge portion is formed in the flap 25 and the front wall 22.

The flap 25 has a first flap 25a and a second flap 25b. The second flap 25b is superposed (laminated) and joined to the upper surface (outer surface) of the first flap 25a. In the first figure, the portion covered by the second flap 25b is indicated by a broken line in the first flap 25a. As shown, the horizontal projection area of the first flap 25a is larger than that of the second flap 25b, and the outer shape of the flap 25 is substantially defined by the first flap 25a. The second flap 25b is folded at the hinge side end portion of the inner casing 2, and is folded at the opening end side of the inner casing 2 with a folding line 28 extending from the upper end edge of the front wall 22 and formed along the upper end edge. In other words, the second flap 25b is a flap extending from the joint edge portion 7 of the front wall 22 as a base end, and is folded (refolded) from the joint edge portion 7 to the first flap 25a side, and overlapped by the first fold The outer surface (upper surface) of the sheet 25a. Then, the second flap 25b is bonded to the first flap 25a by a bonding material, and is fixed integrally with the first flap 25a.

Next, the detailed configuration of the outer cover 3 will be described. The outer cover 3 has a front wall portion 31 that is coupled to the inner casing 2 by a hinge 4, and a side wall portion 32 that is erected from the opposite side of the hinge 4 of the front wall portion 31 from the front wall portion 31. The upper wall portion 33 is connected to be orthogonal to the upper ends of the front wall portion 31 and the side wall portion 32, and the lower wall portion 34 is connected to the lower ends of the front wall portion 31 and the side wall portion 32 so as to be orthogonal to each other.

The outer cover 3 is configured to freely open and close the take-out opening 26 of the inner casing 2 as described above. Fig. 3 is a plan view of the package 1 in a state in which the outer cover 3 is opened. Further, Fig. 4 is a plan view of the package 1 in a state in which the outer cover 3 is closed. The third figure corresponds to the state shown in Fig. 1, and the fourth figure corresponds to the state shown in Fig. 2. As shown in Figure 2 As shown in Fig. 4, when the outer cover 3 is closed, the upper and lower wall portions 33 and 33 of the outer cover 3 are used to close the outlet 26 of the inner casing 2. Further, when the outer cover 3 is closed, the front wall portion 31, the side wall portion 32, the upper wall portion 33, and the lower wall portion 34 of the outer cover 3 are respectively disposed on the front wall 22, the side wall 23B corresponding to the inner casing 2 side, The flaps 25 and the bottom wall 24 are opposed to each other.

As shown in Figs. 1 and 3, the upper wall portion 33 of the outer cover 3 has a substantially trapezoidal shape. The upper wall portion 33 includes an end portion on the side of the hinge 4 (hereinafter referred to as "hinge side end portion") 33a and a width from the hinge side end portion 33a in the width direction of the upper wall portion 33 to a predetermined predetermined interval. The area is referred to as "hinge area 33b". The hinge proximal region 33b may be referred to as a region closer to the hinge side end portion 33a. Further, in the upper wall portion 33, a region located farther from the hinge 4 (hinge side end portion 33a) than the hinge proximal region 33b is referred to as a "hinge distal region 33c".

As shown in Fig. 3, the hinge distal region 33c of the upper wall portion 33 has a substantially rectangular shape, and the hinge proximal region 33b has a triangular shape. The depth dimension of the upper wall portion 33 of the hinge proximal region 33b is smaller than the depth dimension of the hinge distal region 33c. In more detail, the hinge proximal region 33b of the upper wall portion 33 is formed to be closer to (close to) the hinge side end portion 33a, and its depth dimension becomes smaller. Further, in the upper wall portion 33, the depth dimension of the hinge side end portion 33a is substantially zero. As a result, the edge portion on the free end side of the hinge proximal region 33b (the edge portion on the opposite side to the front wall portion 31, hereinafter referred to as the "free end side edge portion") is substantially on the hinge side end portion 33a. The front wall portion 31 is in contact. Then, the free end side edge portion of the hinge proximal region 33b of the upper wall portion 33 becomes larger from the hinge side end portion 33a as it goes away from the width direction, and the protruding dimension (depth direction) from the front wall portion 31 becomes larger.

Furthermore, as shown in FIG. 3, the first flap 25a is along the inner box 2 The width direction, which produces a 3-step change. When the first flap 25a is divided into the first region 251, the second region 252, and the third region 253 from the side of the hinge 4, the first region 251 corresponds to the region of the connection section Zc, and the depth dimension thereof is the same as that of the inner box 2. The depth dimensions are the same. That is, the first region 251 of the first flap 25a covers the open end of the inner casing 2 from the front wall 22 to the rear wall 21. In this way, the operation of the flap 25 can be suppressed, and the flap 25 can be more reliably prevented from interfering with the outer cover 3 and the stored object. The second region 252 of the first flap 25a is in a region sandwiched by the first region 251 and the third region 253, and gradually decreases in size from the hinge 4 away from the depth dimension thereof. The second region 252 has the smallest depth dimension at the boundary portion with the third region 253. The third region 253 is disposed on the end side of the inner casing 2 opposite to the hinge 4, and has a certain depth dimension irrespective of the separation dimension from the hinge 4.

Further, a handle portion 35 as a substantially semicircular recess is formed in the side wall portion 32 of the outer cover 3. This handle portion 35 is provided to assist the opening operation when the consumer (the operator of the package 1) opens the outer cover 3 by holding the finger. Further, in the position where the handle portion 35 is disposed on the side wall portion 32, it is preferable to be disposed near the center of the height direction of the side wall portion 32, preferably at a position close to either the upper portion or the lower portion. In the package 1 of the present embodiment, the handle portion 35 is disposed at a slightly lower height than the center of the side wall portion 32. This is to provide a sealing tape (not shown) for sealing the sealing film of the packaging case 1 in the vicinity of the center of the height of the package 1, in order to prevent the opening tape and the handle portion 35 from interfering with each other. Further, the edge portion 36 which forms the boundary between the front wall portion 31 and the side wall portion 32 of the outer lid 3 is formed into a rounded corner (rounded corner) having a round shape.

Further, the package 1 is provided with a slit animation unit 7 (slit animation means) including: a film meter 71 provided on the front wall 22 of the inner casing 2; A sketch display panel 72 is displayed under 71 and with a sketch. The slit animation unit 7 uses a sketch displayed on the sketch display sheet 72 and the film gauge 71, and has a similar principle to a flip-book, and has a visual (such as animated) visual image. The function of the effect.

Fig. 5 is a view showing the film meter 71 and the sketch display sheet 72. The film meter 71 is, for example, on a transparent substrate such as a PET (Polyethylene Terephthalate) film at a predetermined interval, in this example, at an equal interval "X"" The strip area is printed by the printer. The film gauge 71 shown in the figure is "the width of the strip-shaped region" and the "interval between the strip-shaped regions" are all set to be equal by "X". Further, as shown in Fig. 1, the front wall 22 of the inner casing 2 is formed by means of a window hole 22a for arranging the gauge meter 71, and for measuring the window 22a for the front wall 22. The film meter 71 is attached to the front wall 22 (the edge of the gauge window hole 22a). In the present embodiment, the gauge hole 22a is formed in a rectangular shape, but may have another shape. Further, as shown in Fig. 1, the strip-shaped region (lattice) of the film meter 71 is provided with a film gauge 71 so as to be parallel to the vertical direction (height direction) of the front wall 22 of the inner casing 2.

The sketch display sheet 72 has a substantially rectangular shape, and the sketch 72a composed of the composite image is displayed by printing or the like. The sketch display sheet 72 is disposed on the storage space side of the package 6 (cigarette 61) in the inner casing 2 such that the display area of the sketch 72a is superimposed on the film gauge 71. Specifically, the sketch 72a of the sketch display sheet 72 faces the film gauge 71 side, and is arranged such that the sketch display sheet 72 is sandwiched between the outer surface of the inner package 6 and the film meter 71.

The sketch 72a displayed on the sketch display sheet 72 is composed of a composite image as described above. This composite portrait, for example, will be based on a certain pattern at predetermined intervals. It is a portrait of an intermediate portrait composed of a plurality of "residual images" and "fragments". In the fifth drawing, there are shown some examples in which a first intermediate image having a star as a keynote and a second intermediate image having a circle as a key are combined to form a composite image. Further, here, each of the first intermediate image and the second intermediate image are extracted at equal intervals "X". Then, when the first intermediate image and the second intermediate image are combined, the composite image is formed such that the portion of the "middle piece" of the first intermediate image coincides with the "afterimage" portion of the second intermediate image.

When the film meter 71 is superimposed on the composite image of the sketch 72a, and the sketch display sheet 72 and the film sheet 71 are relatively slid, as shown in FIG. 5, the "after-image" of the first intermediate image is set on the film meter 71. In the transparent region between the strip regions, the pattern of the first intermediate image display, that is, the star pattern is recognized (A in FIG. 5). On the other hand, when the "after-image" of the second intermediate image is located in a transparent region between the strip-shaped regions of the film meter 71, the pattern of the second intermediate image display, that is, the circular pattern is recognized (Fig. 5) B)

Then, when the relative sliding motion of the sketch display sheet 72 and the film sheet 71 is performed at a moderate speed, it is recognized as a star pattern and a circular pattern dynamically in the human eye, so that an animation can be obtained. The visual effect. In addition, the technique of the slit animation itself is generally known, and detailed description is omitted here, and the number of intermediate images incorporated in the composite image may be three or more.

As shown in Fig. 1, the front wall 22 of the inner casing 2 is formed between the gauge window hole 22a and the hinge 4 in the vertical direction of the front wall 22 (i.e., the extending direction of the hinge 4). The rectangular slit opening 22b. The opening size of the slit opening 22b in the longitudinal direction is larger than the height direction of the front wall 22 by the gauge hole 22a. The opening size is slightly narrow. More specifically, the lower end position of the slit opening 22b is substantially equal to the lower end position of the gauge window hole 22a. Further, the upper end position of the slit opening 22b is disposed at a position slightly lower than the upper end position of the gauge window hole 22a. In the present embodiment, the slit opening 22b is disposed at the hinge side end portion of the front wall 22.

Further, the height of the end portion of one of the sketch display sheets 72 is slightly narrower than the opening size of the slit opening 22b in the long-hand direction, and the end portion of the sketch display sheet 72 is inserted into the slit opening 22b. In this manner, the sketch display sheet 72 retains most of the area including the sketch 72a in the inner portion of the inner casing 2, and is fixed to the outer lid 3 at the end portion exposed to the outside through the slit opening 22b. The inner surface of the front wall portion 31.

Here, in the sketch display sheet 72, the end portion region to which the inner surface of the front wall portion 31 is joined and fixed is referred to as a "fixed end portion region 72b". In the example shown in Fig. 1, the fixed end portion 72b of the sketch display sheet 72 is fixed in the front wall portion 31 at a position close to the hinge 4. Thus, by fixing one end of the sketch display piece 72 to the front wall portion 31 of the outer cover 3, when the outer cover 3 is opened from the closed state, the sketch display piece 72 is opened from the slit in conjunction with the opening operation of the outer cover 3. The hole 22b is drawn up by a predetermined amount. Conversely, when the outer cover 3 is closed from the open state, the sketch display piece 72 is pulled into the slit opening 22b by a predetermined amount in conjunction with the closing operation of the outer cover 3. That is, the package 1 of the present embodiment is configured such that the sketch display sheet 72 and the film sheet 71 slide relative to each other in conjunction with the switching operation of the outer cover 3. In this manner, when the operator switches the cover 3, in conjunction with the switch operation, the sketch display sheet 72 can be slid relative to the film meter 71, and a visual effect of generating the slit animation described in FIG. 5 can be obtained. Therefore, the package 1 can be given added value and the consumer's willingness to purchase can be promoted.

[blank]

Next, the blank for the package constituting the package 1 will be described. Fig. 6 is a view showing a first blank B1, and Fig. 7 is a view showing a second blank B2. The first blank B1 is formed by folding (assembling) the sheet material of the inner casing 2. Further, the second blank B2 is formed by folding (assembling) the sheet material of the outer cover 3. That is, it can be said that the first blank B1 and the second blank B2 are the sheet materials for unwinding the inner box 2 and the outer lid 3, respectively. Then, the first blank B1 and the second blank B2 are folded, and an appropriate portion is joined to form the package 1 shown in Fig. 1. In addition, although the first blank B1 and the second blank B2 may use a paper such as a cardboard or a Manila cardboard or a resin such as a plastic sheet, the material is not limited thereto. In addition, in the description of the blank of Fig. 6 and Fig. 7, the upper and lower directions of the figure are used as a reference.

As shown in Fig. 6, the first blank B1 has the rear wall 21 which is the rear panel 21 of the inner casing 2, and the side wall 23A which becomes the inner casing 2 is connected to the both side edges of the rear wall panel P1 via the folding line. Inner panel P2A, P2B of 23B. Further, at the lower end edge of the rear wall panel P1, the first top panel P3 which is the first flap 25a of the flap 25 is connected via a folding line. Further, at the upper edge of the rear wall panel P1, a bottom wall panel P4 which becomes the bottom wall 24 of the inner casing 2 is connected through a folding line. Further, the lower end edges of the inner plates P2A, P2B are bonded to the first top plate P3, and the reinforcing plates P5A, P5B forming the reinforcing action are connected through the folding lines. Further, the upper end edges of the inner side panels P2A, P2B are attached to the bottom wall panel P4, and the reinforcing plates P6A, P6B forming the reinforcing action are connected through the folding lines.

Further, at the upper end edge of the bottom wall panel P4, the front wall panel P7 which becomes the front wall 22 of the inner casing 2 is connected through a folding line. An opening portion serving as the gauge window hole 22a and the slit opening 22b is formed in the front wall panel P7. In addition, two on the front wall panel P7 The side wires are connected to the side wall panels P8A, P8B which become the side walls 23A, 23B of the inner casing 2 through the folding wires. Further, between the front wall panel P7 and the side wall panel P8B, a plurality of folding lines are arranged at a short pitch, whereby the edge portion 5 having a circular shape is formed. Further, on the upper end edge of the front wall panel P7, the second top panel P9 which is the second flap 25b which is the flap 25 is connected via a folding line. Further, instead of the plurality of folding lines, the circular shape of the edge portion 5 may be formed by a plurality of pressing lines.

Next, the second blank B2 shown in Fig. 7 has a front cover P10 which is the front wall portion 31 of the outer cover 3. Then, a side cover P11 which becomes the side wall portion 32 is connected to the side edge of one of the front cover plates P10 via a folding line. Between the front cover P10 and the side cover P11, a plurality of folding lines are arranged at a short pitch, whereby the edge portion 36 having a circular shape is formed. Further, in the side cover P11, on the side edge on the opposite side of the front cover P10, the inner side panel P12 which becomes the side wall part 32 of the outer cover 3 is connected by the folding line. The inner side panel P12 is folded back on the side cover P11, and both sides overlap each other. The inner side panel P12 is a reinforcing side cover P11 and becomes an inner wall of the side wall portion 32. The inner side panel P12 forms the side wall portion 32 of the outer lid 3 together with the side cover panel P11. The inner side panel P12 which is folded back on the side cover P11 may also be joined to the side cover P11 or may not be engaged therewith. When the inner side panel P12 is not joined to the side cover panel P11 and is merely folded back and overlapped, the inner side panel P12 is biased toward the inner side of the outer lid 3 by the reflexing force (the inner panel P12 is separated from the side cover panel P11) Expansion. According to this, after the package 1 is assembled, the inner side panel P12 is pushed to the inner box 2 when the outer cover 3 is closed, so that a high frictional force is generated between the inner side panel P12 and the inner box 2. As a result, it is possible to suppress the operator from inadvertently opening the outer cover 3. Further, the side cover P11 and the inner side plate P12 are formed with a handle portion 35 in an opening manner. In addition, the upper end edge and the lower end edge of the side cover P11 are respectively connected and reinforced by a folding line. Plates P13 and P14 will be described later with respect to these members.

On the upper end plate of the front cover P10, the upper cover P15 and the inner top plate P16 which become the upper wall portion 33 are sequentially connected through the folding line. Further, on the lower end edge of the front cover P10, a lower cover P17 and an inner bottom plate P18 which become the lower wall portion 34 are sequentially connected through the folding line. Further, in the front cover P10, on the opposite side of the side cover P11, the side wall panel P19 and the rear wall panel P20 are sequentially connected through the folding line.

The inner top plate P16 is folded back on the upper cover P15, and both sides overlap each other. The inner top plate P16 reinforces the upper cover P15 and becomes the inner wall of the upper wall portion 33. Here, the reinforcing plate P13 is joined to both of the plates in a state of being sandwiched between the upper cover P15 and the inner top plate P16. The reinforcing plate P14 is joined to both of the plates in a state of being sandwiched between the lower cover P17 and the inner bottom plate P18. The side wall panel P19 is bonded to the outer surface of the side wall panel P8A of the first blank B1 to form an outer wall surface of the side wall 23A of the inner casing 2. Further, the rear wall panel P20 is formed on the outer surface of the rear wall panel P1 of the first blank B1 to form the outer wall surface of the rear wall 21 of the inner casing 2.

The first blank B1 and the second blank B2 configured as described above are respectively folded in the folding lines indicated by broken lines in FIGS. 6 and 7. Then, in the first blank B1, the reinforcing plates P6A, P6B are superposed on the bottom wall panel P4. Further, the inner side plates P2A, P2B are joined to the inner surface sides of the side wall plates P8A, P8B, respectively. Moreover, the reinforcing plates P5A and P5B are joined to the inner surface side of the first top plate P3, and the second top plate P9 is superposed on the outer surface side of the first top plate P3, and both are joined. Further, the folding of the first blank B1 is performed in a state where the separately prepared inner package 6 is placed on, for example, the rear wall panel P1. At this time, the sketch display sheet 72 can also be placed on the inner package 6. Then, when the first blank B1 is folded, the separately prepared film gauge 71 is joined to the opening at The front wall panel P7 is measured by the edge of the window hole 22a.

Further, when the second blank B2 is folded, as described above, the reinforcing plate P13 is joined to both the plates by sandwiching the reinforcing plate P13 between the upper cover P15 and the inner top plate P16, and The reinforcing plate P14 is sandwiched between the lower cover P17 and the inner bottom plate P18, and the reinforcing plate P14 is joined to both of the plates to form the outer cover 3. Further, by joining the side wall panel P19 and the rear wall panel P20 to the outer surface of the side wall panel P8A of the first blank B1 and the outer surface of the rear wall panel P1 as described above, the outer cover 3 and the inner casing 2 are integrated. . Next, the end portion of the sketch display sheet 72 through which the slit plate opening 22b is inserted into the front wall P7 of the first blank B1 is joined to the inner surface of the front cover P10 of the second blank B2. In this way, the slit animation portion 7 is formed, and the assembly of the package 1 is completed.

[Effect]

Next, the operation contents and effects of the switch package 1 will be described. In the package 1 of the present embodiment, as described above, the flap 25 composed of the first flap 25a and the second flap 25b retains one of the open ends of the inner casing 2 as the take-out port 26. And plug the retained part on one side. By providing the flap 25 in the inner casing 2, the cigarette (winding) 61 can be protected and the tobacco sheet can be prevented from being scattered or the like.

The package 1 is a side opening type (lateral opening type) package, and is disposed to extend in a direction in which the hinges 4 and the flaps 25 of the inner box 2 are orthogonal to each other in the plane direction. On the other hand, the upper wall portion 33 of the outer cover 3 is disposed in parallel with the flap 25 of the inner casing 2, and when the outer cover 3 is closed, it is slowly approached to the flap 25. Next, the upper wall portion 33 of the outer cover 3 is slid by partially overlapping the flaps 25 of the inner casing 2, and finally covers the entire take-out port 26, and the closing operation of the outer cover 3 is completed.

Fig. 8 is a view showing a conventional side open type package 1A. in In the conventional packaging case 1A, the front side of the open end of the inner box 2A is left as the take-out port 26A, and the remaining rear side is covered by the flap 25A. Then, the outer cover 3A is rotatably connected to the inner casing 2A by the hinge 4A formed along the edge portion forming the boundary between the rear wall and the side wall of the inner casing 2A. In the conventional packaging case 1A, when the outer lid 3A is closed, the edge portion on the free end side of the upper wall portion 33A easily interferes with the flap 25A and the inner wrapping material 62A containing the cigarette. As a result, in the conventional packaging case 1A, the flap 25A and the inner wrapping material 62A are bent or broken due to interference with the upper wall portion 33A of the outer cover 2A, and the appearance is liable to be deteriorated. Further, the end portion of the inner wrapping material 62A which is folded back due to the collision with the upper wall portion 33A may be sandwiched between the upper wall portion 33A and the flap 25A, and the switch of the outer cover 2A is repeated as a result of repeated switching. The cause of damage to the inner packaging material 62A.

In the package 1 of the present embodiment, the section from the end on the hinge 4 side of the inner box 2 to the middle position in the width direction of the inner box 2 is referred to as the connection section Zc, and the flap 25 is front and front. The upper ends of the walls 22 are connected. Accordingly, in the connection section Zc in the width direction of the inner casing 2, the upper portion of the package 6 (the cigarette 61 and the inner wrapping material 62) accommodated in the inner casing 2 is covered by the flap 25. Therefore, interference (collision, contact) between the upper wall portion 33 on the side of the outer cover 3 and the inner package 6 is suppressed. That is, it is possible to suppress the case where the inner wrapping material 62 of the inner package 6 is bent or the inner wrapping material 62 is sandwiched between the upper wall portion 33 and the flap 25 to be broken.

Further, in the connection section Zc, the upper wall portion 33 of the outer cover 3 does not sneak into the lower side of the flap 25, so that the flap 25 can be prevented from being bent. According to this, according to the package 1 of the present embodiment, it is possible to suppress the damage of the inner package 6 and the flap 25 or the appearance of the package to be damaged.

In particular, in the side opening type package 1, it is extended to The hinge 4 in the height (upper and lower) direction of the package is the center switch cover 3, so that when the cover 3 is closed, the closer to the hinge 4, the more the upper wall portion 33 of the cover 3 is closer to the storage at the steep angle. The inner package 2 has a package 6 (cigarette 61 and inner wrap 62).

In contrast, according to the package 1 of the present embodiment, the inner package 6 is covered by the flap 25 by connecting the front wall 22 and the flap 25 in the proximal region of the inner box 2 and the hinge 4. . In this manner, when the outer cover 3 is closed, even if the upper wall portion 33 approaches the inner package 6 at a steep angle, the upper wall portion 33 does not collide with the inner package 6, and the damage of the inner package 6 can be appropriately suppressed.

Further, in the package 1, the flap 25 covering a part of the open end of the inner box 2 is configured as a laminated structure of the first flap 25a and the second flap 25b. Next, in the connection section Zc of the inner casing 2, the second flap 25b is extended from the upper end edge of the front wall 22, and is folded on the open end side with the folding line 28 formed along the upper end edge as a boundary, and The folded second flap 25b is joined and fixed to the upper surface of the first flap 25a.

According to this, in the connection section Zc of the inner casing 2, the integrally connected second flaps 25b are arranged so as to surround the opening end side from the front wall 22 side of the inner casing 2. As a result, at the joint portion between the flap 25 and the front wall 22, when the outer lid 3 is closed, a gap, a recess, and the like which are caught by the front end portion of the upper wall portion 33 are not generated, and the outer cover 3 can be more reliably suppressed. The interference of the upper wall portion 33 causes the flap 25 to be bent or broken.

Further, in the package 1 of the present embodiment, the depth dimension of the vicinity of the hinge 4 in the upper wall portion 33 of the outer cover 3 is made small. That is, the depth dimension (the protruding dimension from the front wall portion 31) of the hinge proximal region 33b of the upper wall portion 33 is made smaller than the hinge distal region 33c. According to this, the upper wall portion 33 can be made The interference between the hinge proximal region 33b and the flap 25 of the inner box 2 and the inner package 6 is less likely to occur. Therefore, damage of the flap 25 of the inner box 2 and the inner package 6 can be appropriately suppressed, and the appearance of the package 1 can be prevented from being damaged.

On the other hand, with respect to the hinge distal region 33c of the upper wall portion 33, compared with the hinge proximal region 33b, it can be said that the interference of the upper wall portion 33 with the flap 25 and the inner package 6 is relatively uncomfortable when the outer cover 3 is closed. . Therefore, with respect to the hinge distal region 33c of the upper wall portion 33, even if the depth dimension is enlarged, the interference between the upper wall portion 33 and the flap 25 is not remarkable as compared with the hinge proximal region 33b. Then, in the hinge distal region 33c of the upper wall portion 33, by setting the depth dimension to be larger than the depth dimension of the hinge proximal region 33b, it is possible to sufficiently ensure formation in the distal region 33c corresponding to the hinge. The depth opening width of the exit 26 of the area. In this way, it is helpful to increase the ease of taking out the cigarette 61 passing through the take-out port 26.

Further, in the package 1 of the present embodiment, the closer to the hinge side end portion 33a, the smaller the depth dimension of the hinge proximal region 33b of the upper wall portion 33 is. In other words, the hinge proximal region 33b of the upper wall portion 33 is cut obliquely, and the edge portion on the free end side of the upper wall portion 33 is formed as an inclined edge portion. Thus, in the hinge proximal region 33b of the upper wall portion 33, the hinge proximal region 33b of the upper wall portion 33 can be appropriately avoided by gradually decreasing the depth dimension as approaching the hinge example end portion 33a. Interference with the flap 25 of the inner box 2 and the inner package 6.

Further, according to the above configuration, the free end side edge portion of the hinge proximal region 33b of the upper wall portion 33 is formed as an inclined edge portion, so that a steep step is not formed at the free end side edge portion in the middle of the hinge proximal region 33b. . In this way, when the outer cover 3 is closed, the free end side edge portion of the upper wall portion 33 becomes less likely to catch the flap 25 and the inner package 6 and the like. On the other hand, in the hinge proximal region 33b of the upper wall portion 33, By gradually increasing the depth dimension as it moves away from the hinge side end portion, the depth opening width of the outlet 26 of the region far from the hinge 4 can be sufficiently ensured. Therefore, there is an advantage that the ease of taking out the cigarette 61 passing through the take-out port 26 can be appropriately raised within a range in which the interference of the flap 25 of the inner box and the inner package 6 can be avoided.

Further, according to the package 1 of the present embodiment, since the depth dimension of the hinge-side end portion 33a of the upper wall portion 33 is substantially zero, the upper wall portion can be more reliably suppressed when the outer cover 3 is closed. The hinge side end portion 33a of 33 causes the flap 25 and the inner wrapping material 62 to be damaged.

Further, in the package 1 of the present embodiment, the outer cover 3 is connected to the inner case 2 by transmitting the hinge 4 formed along the edge of the boundary between the front wall 22 and the side wall 23A of the inner box 2. According to this, when the outer cover 3 is closed, the side end of the front wall portion 31 covering the front wall 22 of the inner casing 2 can be directly joined to the inner casing 2 by a hinge. Therefore, as compared with the case where the outer cover 3 is hinged at the edge of the boundary between the rear wall 21 and the side wall 23A forming the inner casing 2, the hinge proximal region of the upper wall portion 33 can be made when the outer cover 3 is closed. The free end side edge portion of 33b approaches the inner casing 2 (the flap 25 and the inner wrapping material 62, etc.) at a gentle angle. As a result, when the outer cover 3 is closed, the upper wall portion 33 is less likely to interfere with the flap 25 and the inner wrapper 62, and the inner wrapper 62 can be more easily caught between the upper wall portion 33 and the flap 25. Further, by forming the hinge 4 on the side of the front wall 22 and setting the depth dimension of the hinge side end portion 33a of the upper wall portion 33 to be substantially zero, the rigidity of the outer cover 3 (even the package 1) can be suppressed from becoming low. .

As described above, according to the package 1 of the present embodiment, when the outer cover 3 is closed, the outer cover 3 is prevented from interfering with the object to be stored, the flap, and the like, so that damage or appearance of the object and the flap can be suppressed. Subject to damage. Furthermore, in In the present embodiment, the section from the end portion on the hinge 4 side of the inner casing 2 to the intermediate position in the width direction of the inner casing 2 is the connection section Zc, and the flap 25 is connected to the upper end of the front wall 22, but The setting range of the connection section Zc is not limited to the example of the above embodiment. The flaps 25 can also be connected to the front wall 22 in a connection section of at least a part of the width direction of the inner casing 2. Thus, an effect is obtained in which the flap 25 is connected to the front wall 22 by at least a portion of the width direction of the inner casing 2, and when the outer lid 3 is closed, the upper wall portion of the outer lid 3 is suppressed. 33 sneaked into the lower side of the flap 25 (on the side of the storage space of the object to be stored) or collided with the flap 25. As a result, it is possible to suppress the damage of the object and the flap 25 of the package 1 or the appearance of the package 1 from being damaged.

The preferred embodiments of the present invention have been described above, and the above-described embodiments can be modified as appropriate without departing from the spirit and scope of the invention. Further, in the above-described embodiment, an appropriate application example of the object to be stored in the package 1 is described in the case where the cigarette product such as the filter cigarette and the non-sucking tobacco is stored in the package, but Not limited to this, for example, articles such as candy and chewing gum may be stored in the package 1.
