Patent Document 1: Japanese Patent No. 3131405

A package having a flap-shaped cover sheet can be formed from a single piece of blank material, which is excellent in seeking efficient use of resources. However, the package having the tongue-shaped cover sheet usually has a folding line at the connection portion between the cover sheet and the outer casing main body and the connection portion between the cover sheet and the tongue piece, and the resilience of the original material to be restored is restored by the folded material. , The insert piece is easily detached from the insertion opening, and the closure property is deteriorated.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a related art of a package having a flap-shaped cover sheet which is better than conventional ones.

In order to solve the above problems, the package having the flap cover sheet of the present invention employs the following means. That is, the package having the flap-shaped cover sheet of the present invention comprises: an outer casing main body having an open surface and accommodating articles therein; and a tongue-shaped cover sheet connected to the rear edge of the opening surface and having an opening and closing a cover portion covering the open surface and a tongue portion connected to the cover portion; and an insert piece formed in an insertable manner, the insert piece being formed on the outer side when the tongue cover cover is closed An insertion opening of one of the front wall of the case main body and the tongue portion is formed on the other side, and is formed to be formed on both the tongue portion and the front wall, and the insertion piece is inserted in the insertion when the tongue cover piece is closed. The engaging portion that will be engaged with each other during the process of the mouth.

The package with a flap-shaped cover sheet according to the present invention is characterized in that, in the case where the insertion opening is provided in the front wall of the outer casing main body, an insertion piece is provided on the tongue portion of the tongue-shaped cover sheet, and the insertion opening is provided on the tongue portion of the tongue-shaped cover sheet. In the case, an insertion piece is provided on the front wall of the outer casing main body.

According to the package having a flap-shaped cover sheet according to the present invention, when the insert sheet is inserted into the insertion opening when the flap cover sheet is closed, the engaging portions formed on both the front wall and the tongue portion of the outer box main body are mutually stuck. Therefore, it is possible to suppress the insertion piece from being accidentally detached from the insertion opening. Therefore, the closure property of the package having the flap cover sheet can be improved more than ever. Further, the engaging portion may be composed of a locking piece provided on the front wall side and a locking piece provided on the tongue side. Composition.

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

According to the present invention, the closure property of the package having the flap cover sheet can be improved more than ever.

Hereinafter, an embodiment of a package having a flap-shaped cover sheet (hereinafter simply referred to as a "package") according to the present invention will be described with reference to the drawings. The object to be accommodated in the package to which the present invention is applied is not particularly limited, but the embodiment is described by taking a case where the cigarette is housed in the package.

<First embodiment>

Fig. 1 and Fig. 2 are perspective views of the package 1 according to the first embodiment, showing a state in which the package 1 is viewed from the front right oblique side. The package 1 includes an outer casing main body 2 and a tongue-shaped cover sheet 3. An opening is formed in the upper surface of the outer casing main body 2. Reference numeral 20 denotes an opening face formed at the upper end of the outer casing main body 2. The tongue cover sheet 3 is a cover member that is connected to the rear edge of the opening surface 20 of the outer casing main body 2 and that opens and closes the opening surface 20. In the state shown in Fig. 1, the flap cover sheet 3 is closed, and in the state shown in Fig. 2, the flap cover sheet 3 is opened. Further, the package 1 has a so-called clutch shape, and may also be referred to as a clutch type package.

The outer casing main body 2 is a casing having a substantially cubic shape, and inside is a package (hereinafter referred to as "inner package") 4 in which a cigarette is housed as shown in Fig. 3. The inner package 4 is a package in which a cigarette (not shown) is wrapped by the inner wrapping material 5. The inner packaging material 5 is a sheet-shaped aluminum vapor-deposited paper having, for example, a rectangular shape, and includes a paper substrate and an aluminum film deposited on the surface thereof. 5a and 5b shown in Fig. 3 are trapezoidal shapes formed by folding the outer peripheral edges of the inner covering members 5 into each other. a pair of side flaps. In the present embodiment, the tobacco bundle is wrapped by the inner wrapping material 5 so that the side flaps 5a and 5b are disposed facing the circumferential surface thereof instead of the end portion in the longitudinal direction of the cigarette. Therefore, when the consumer wants to take out the cigarette, the end of the cigarette can be prevented from being caught in the inner wrapping material 5. Further, the chain line shown in Fig. 3 represents a cutting line. The consumer who purchases the package 1 containing the inner package 4 can take the cigarette out by grasping the side flap 5a on the front side of the inner package 4 and pulling it apart, and dividing the cutting line as a boundary. The exterior of the packaging material 5.

The outer casing main body 2 has a front wall 21, a rear wall 22, a left side wall 23, a right side wall 24, and a bottom wall 25, and is shaped by these members. The front wall 21 and the rear wall 22 have the same shape and are disposed opposite each other. The front wall 21 and the rear wall 22 are coupled to each other by the left side wall 23, the right side wall 24, and the bottom wall 25. Here, the edge portion 26a located at the boundary between the front wall 21 and the bottom wall 25, and the edge portion 26b positioned at the boundary between the rear wall 22 and the bottom wall 25 are formed with rounded corners (arc edges) having a circular arc shape.

Further, a slit-shaped insertion opening portion 27 is provided in the front wall 21 of the outer casing main body 2. The insertion opening portion 27 is a portion that is disposed above the center in the height direction of the front wall 21, that is, a portion that is close to the opening surface 20. Here, FIG. 1 and FIG. 2 show the respective directions of the front, the rear, the top, bottom, and left and right of the package 1. Moreover, the up-down direction, the left-right direction, and the front-back direction shown in the drawings correspond to the height direction, the width direction, and the depth direction of the package 1 (outer case main body 2), respectively. As shown in FIGS. 1 and 2, the insertion opening portion 27 extends in the width direction of the front wall 21. Further, the width direction of the package 1 (outer case main body 2) is a dimension along the direction of the trailing edge of the opening face 20. In addition, the box 1 (outside The height direction of the cartridge main body 2) is a dimension orthogonal to the above-described width direction and along the direction of the front wall 21.

In the rear wall 22 of the outer casing main body 2, the upper edge thereof is used as a folding line, that is, the tongue-shaped cover sheet 3 is connected as an automatic hinge. The tongue cover sheet 3 has a cover sheet 31 (cover portion) and a tongue piece 32 (tongue portion) from the side of the rear wall 22. These cover sheets 31 and tabs 32 are connected via a folding line. In other words, the cover sheet 31 and the tongue piece 32 distinguish the tongue-shaped cover sheet 3 by the folding line. Hereinafter, the boundary portion between the rear wall 22 and the cover sheet 31 is referred to as a cover sheet folding portion 33, and the interface portion between the cover sheet 31 and the tongue piece 32 is referred to as a tongue folding portion 34. In the present embodiment, both the cover sheet folding portion 33 and the tongue folding portion 34 are formed with rounded corners having an arc shape.

The cover sheet 31 has a shape and size corresponding to the opening surface 20 of the outer casing main body 2, and a cover member that can openably and closably cover the opening surface 20 by being connected to the rear edge of the opening surface 20. The tongue 32 has the same width as the cover sheet 31, and has a shape that gradually narrows its width once it is stretched. An insertion piece 32a is formed to protrude from the front end side of the tongue piece 32. The width of the insertion piece 32a is formed to be slightly smaller than the insertion opening portion 27 provided in the front wall 21 of the outer casing main body 2.

As shown in Fig. 1, when the flap cover 3 is closed, the tongue 32 overlaps with the front wall 21 of the outer casing main body 2, and the insertion piece 32a of the tongue 32 is inserted into the insertion opening portion 27. Thereby, the cover sheet 31 seals the opening surface 20 of the outer casing main body 2, and restricts access to the cigarettes belonging to the packaged articles housed in the package 1.

Further, as shown in Figs. 1 and 2, the package 1 of the present embodiment is formed such that the longitudinal direction of the cigarette corresponds to the width direction of the package 1. The inner package 4 is housed in the specifications of the outer casing main body 2. Therefore, the package 1 (outer case main body 2) has a width dimension larger than the height dimension. Further, although the drawings are omitted from the drawings 1 and 2, characters, patterns, photographs, and the like are usually printed on the outer casing main body 2 for promotion, advertising, and other purposes. In particular, the front wall 21 of the outer casing main body 2 is more likely to attract the attention of the consumer than the other surfaces, and therefore it is required to secure a larger area on the front wall 21 as a printing space for characters, patterns, and the like.

Here, since the package 1 is a package having a flap-shaped cover sheet, the information display space for promotion, advertisement, and the like of the front wall 21 of the outer casing main body 2 is located below the insertion opening portion 27. Since the upper portion of the insertion opening 27 of the front wall 21 is hidden under the tongue 32 when the flap cover 3 is closed. Therefore, in order to secure more information display space of the front wall 21 of the outer casing main body 2, it is necessary to provide the insertion opening portion 27 at the upper position of the front wall 21, that is, the portion closer to the opening surface 20. In the package 1 of the present embodiment, the insertion opening portion 27 is also provided at a position higher than the center in the height direction of the front wall 21 (that is, on the side of the opening surface 20).

Further, in the package 1 of the present embodiment, since the inner package 4 is housed so that the longitudinal direction of the cigarette coincides with the width direction of the outer casing main body 2, the longitudinal direction of the cigarette and the height of the outer casing main body 2 are made. The height dimension of the front wall 21 itself becomes smaller as compared with the case where the directions are uniform. In this way, the restoring force of the blank generated by the flap folding portion 33 and the tongue folding portion 34 is more specifically that the restoring force of the original material to return to the original shape before being folded is applied to the tongue shape. Since the cover sheet 3 is attached, the insertion piece 32a is easily detached from the insertion opening portion 27. That is, the condition that the flap cover sheet 3 is accidentally opened is liable to occur.

Therefore, the package 1 of the present embodiment is provided with the lock structure 6 for suppressing the above-described problems and improving the lid closure property. The lock structure 6 is formed by the engagement portions formed on the tongue piece 32 and the front wall 21, respectively, and the engagement of the engagement portions is suppressed by the engagement of the engagement portions 32a from the insertion opening portion 27.

The lock structure 6 is composed of a combination of a locking tongue 28 (locking piece) provided on the front wall 21 of the outer casing main body 2 and a folding flap 35 (locking piece) provided inside the tongue piece 32. The locking tab 28 is a rectangular tongue projecting from the upper edge of the front wall 21. In the example shown in Figs. 1 and 2, the locking tabs 28 are provided at two locations on the upper edge of the front wall 21.

The reverse flap 35 is formed by folding the front end side of the tongue piece 32 and partially closing the both end sides of the folded portion on the inner surface of the opposing tongue piece 32. The inverted flap 35 of this embodiment is formed on both sides of the insertion piece 32a. Further, a portion of each of the reverse flaps 35 corresponding to the locking tongue 28 of the front wall 21 in the width direction of the package 1 (hereinafter referred to as "folding engagement portion") 35a is not associated with the tongue 32. Next, the inner ends are followed by the inner faces of the tongues 32. Thereby, a predetermined gap is formed between the flap engaging portion 35a of the inverted flap 35 and the inner surface of the tongue piece 32 to the extent that the locking flap piece 28 is caught when the flap cover sheet 3 is closed. The package 1 of the present embodiment includes two pairs of the reverse flaps 35 and the locking tongues 28 which are engaged with each other when the tongue-shaped cover sheets 3 are closed, but the number thereof is not particularly limited.

Next, the operation state when the package 1 is closed will be described with reference to Fig. 4 . Fig. 4 shows the states of the package 1 from the state in which the flap cover 3 is opened to the closing state. The first to fourth states are displayed from the left side to the right side. In addition, the cross section of the package 1 shown in FIG. 4 corresponds to the first figure. A-A profile.

The first state shown in Fig. 4 is a state in which the package 1 is opened. Further, in the first state, the locking tongue 28 protrudes upward from the upper edge of the front wall 21.

Next, in order to close the package 1, the operator performs a closing operation of the flap cover 3. When the closing operation of the flap cover 3 is started, the outer surface 35b of the reverse flap 35 provided on the tongue 32 abuts against the inner surface 28a of the locking tab 28 provided on the upper edge of the front wall 21. The second state. The inner surface 28a of the locking tab 28 is the one of the locking tabs 28 facing the opening surface 20 of the outer casing main body 2.

In the second state, with the closing operation of the flap cover 3, the outer surface 35b of the inverted flap 35 is pressed against the inner surface 28a of the locking tab 28. Thereby, the posture of the locking tongue 28 is inclined toward the front of the outer casing main body 2 at the boundary with the joint base end of the upper edge of the front wall 21. As described above, when the locking tab 28 is pressed toward the front wall 21 by the folding flap 35, and the insertion piece 32a of the tongue 32 is inserted into the insertion opening portion 27, the third state is obtained. In the third state, the degree of pressing by the locking tongue 28 of the inverted flap 35 is further advanced than the second state.

Next, when the insertion amount (length) of the insertion piece 32a with respect to the insertion opening portion 27 is gradually increased, the outer surface 35b of the inverted flap 35 passes over the inner surface 28a of the locking tongue piece 28 to be in the fourth state. That is, in the process in which the insertion piece 32a is inserted into the insertion opening portion 27, the inverted flap 35 and the locking tongue piece 28 are engaged with each other. Thus, in the fourth state, the reverse flap 35 and the locking tab 28 are engaged with each other to form a locked state, and are sealed by the cover sheet 31. The opening surface 20 brings the package 1 into a closed state. Moreover, when the locking tab 28 passes over the reverse flap 35, that is, when the folding flap 35 and the locking tab 28 are locked to each other to be in a locked state, the locking tab 28 is subjected to the reverse flap 35. Bounce and make a sound. Thus, by the sound emitted when the folding flap 35 and the locking tab 28 are locked to each other, the user can confirm that the package 1 has been surely closed, and the feeling of use of the package 1 can be improved.

According to the package 1 of the present embodiment, even in the state in which the flap cover 3 is closed, there is a cover sheet folding portion 33 between the outer box main body 2 and the cover sheet 31, and between the cover sheet 31 and the tongue piece 32. The restoring force (repulsive force) of the billet generated by the tongue folding portion 34 or the like acts on the flap cover sheet 3, and also because the flap flap 35 and the locking tab 28 are locked to each other, the tongue piece 32 can be suppressed. The insertion piece 32a is detached from the insertion opening portion 27 on the side of the outer casing main body 2. Therefore, the lid closing property of the package 1 having the flap cover sheet can be improved compared to the prior art.

In particular, in the package 1 of the present embodiment, when the cover sheet folding portion 33 and the tongue folding portion 34 are formed in a circular shape, the restoring force of the blank is larger than that in the case of a square shape. . In the packaging case 1, when the inner package 4 is accommodated so that the longitudinal direction of the cigarette is along the width direction of the outer casing main body 2, the insertion of the tongue piece 32 is performed in order to secure a warning space such as a health warning on the front wall 21. The arrangement position of the insertion opening portion 27 into which the sheet 32a is inserted is often in the vicinity of the upper edge of the front wall 21. Under such conditions, according to the package 1, the locking structure 6 composed of the combination of the folding flap 35 and the locking tab 28 which are engaged with each other when the flap cover 3 is closed is provided, so that the tongue can also be suppressed. The cover sheet 3 is accidentally opened.

<Second embodiment>

Next, the package 1A of the second embodiment will be described. Fig. 6 and Fig. 7 are perspective views of the package 1A of the second embodiment. Fig. 8 is a developed view of the blank B2 forming the package 1A. Here, the same components as those of the package 1 of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In the package 1A of the second embodiment, the difference from the package 1 of the first embodiment will be mainly described.

Fig. 6 shows a state in which the flap cover 3 is closed, and Fig. 7 shows the package 1A in a state in which the flap 3 is opened. In the package 1A of the first embodiment, the insertion opening portion 27 into which the insertion piece 32a of the tongue-shaped cover sheet 3 (the tongue piece 32) is inserted is formed by punching the front wall 21, but the second embodiment is in the outer casing main body. The front wall 21 of 2 is provided with an insertion band member 29.

The insertion band member 29 has an inner band member 29a and an outer band member 29b. The inner belt member 29a is connected to the upper edge of the front wall 21, and is folded over the front wall 21 from the folding line. The one end portion of the inner belt member 29a on the side opposite to the connection end of the upper edge of the front wall 21 is connected to the outer belt member 29b via a folding line. The outer belt member 29b is folded back from the folding line with respect to the inner belt member 29a, thereby being superposed on the inner belt member 29a. As shown in Figs. 6 and 7, the outer belt member 29b has a larger size in the width direction of the package 1A than the inner belt member 29a, and both end portions 29c are directly attached to the front wall 21.

Further, a slit-like insertion opening portion 27 is formed at a boundary portion between the inner belt member 29a and the outer belt member 29b, and the insertion opening portion 27 of the tongue piece 32 can be inserted into the insertion opening portion 27. More specifically, when the flap cover 3 is closed, the insertion piece 32a of the tongue 32 is inserted into the inner band member 29a. A gap with the outer band member 29b is inserted into the insertion opening portion 27. Thus, since the insertion piece 32a is inserted into the insertion opening portion 27, the opening face 20 of the outer casing main body 2 is sealed by the cover sheet 31 of the tongue-shaped cover sheet 3. When the closing operation of the flap cover 3 is performed, the reverse flap 35 and the locking tab 28 are engaged with each other, thereby forming a locked state. Therefore, similarly to the package 1 of the first embodiment, it is possible to prevent the insertion piece 32a of the tongue piece 32 from being accidentally detached from the insertion opening portion 27 on the side of the outer casing main body 2.

The blank B2 shown in Fig. 8 is at the lower end of the front wall panel P1, and the insertion tape inner panel P14 which forms the inner belt member 29a of the insertion tape member 29 is connected. An insertion tape outer panel P15 which is formed on the opposite side of the front wall panel P to form the outer side belt member 29b of the insertion belt member 29 is connected to the insertion tape inner panel P14. A folding line is formed between the insertion tape inner panel P14 and the insertion tape outer panel P15, and a perforation of the opening portion R2 is formed so as to span both sides. In the example shown in Fig. 8, the opening portion R2 has an elliptical shape, and its major axis position coincides with the position of the folding line. However, the shape of the opening portion R2 can be appropriately changed. Further, the width of the insertion tape outer panel P15 is larger than the width dimension of the insertion tape inner panel P14. The width dimension herein refers to the dimension in the package 1A after assembly corresponding to the direction of the width direction, and is a dimension along the direction of the fold-in line inserted between the tape inner panel P14 and the insertion tape outer panel P15.

Similarly to the above-described blank B1, the blank B2 is formed by folding back from the folding line indicated by the one-dot chain line to form the outer casing main body 2 and the tongue-shaped cover sheet 3, and the package shown in Fig. 6 is obtained. 1A. The insertion inner panel P14 is folded into the outer surface side of the front wall panel P1. Next, the insertion tape outer panel P15 is folded in from the folding line so as to be superposed on the insertion tape inner panel P14.

As described above, since the width of the insertion tape outer panel P15 is larger than that of the insertion tape inner panel P14, both end portions of the insertion tape outer panel P15 directly overlap the front wall panel P1. In the present embodiment, the portion (both end portions) of the insertion outer panel P15 that directly overlaps the front wall panel P1 is attached to the front panel P1. Therefore, the insertion tape member 29 is fixed to the front wall 21 of the outer casing main body 2.

Further, at the time of assembly of the package 1A, the insertion of the inner panel P14 and the insertion of the outer panel P15 do not end each other. Therefore, a gap is formed between the insertion pocket inner panel P14 and the insertion tape outer panel P15.
