  2. Description of the Related Art Conventionally, a hinge lid type package is widely known as one form of a box type hard package that accommodates a rod-like smoking article such as a cigarette or a filter cigarette. In this type of hinge lid type package, the lid generally has a box shape, but a tan grid type package having a tan grid instead of the box type lid is also known (for example, Patent Documents). 1).

  The tan grid of the tan grid type package is usually connected to the edge of the opening surface of the case body via a folding line, and a lid that covers the opening surface so as to be openable and closable, and is connected from the lid through the folding line. With tongue. As an example of a tangrid type package, there is known a front wall of a case body provided with an insertion port into which an insertion piece formed on the front end side of a tongue can be inserted when the opening surface is covered with a lid. ing.

Japanese Patent No. 3131405

  The tan grid type package can be formed from a single blank and is excellent in terms of effective use of resources. However, tangrid type packages usually have folding lines at the connecting part between the lid and the case main body and the connecting part between the lid and the tongue, and the inserted blank is inserted by the restoring force to return to the original state. There is a possibility that the inserted piece is easily pulled out from the mouth and the lid closing property is deteriorated.

  This invention is made in view of such a subject, Comprising: The objective is to provide the technique regarding the tan grid type package excellent in lid | cover closure property compared with the past.

  In order to solve the above problems, the tan grid type package according to the present invention employs the following means. That is, the tan grid type package according to the present invention has a case main body having an opening surface and capable of accommodating articles therein, and a lid portion that is connected to a rear edge of the opening surface and covers the opening surface so as to be freely opened and closed. And a tongue grid having a tongue portion connected to the lid portion, and a plug formed on either the front wall of the case body or the tongue portion when the tongue grid is closed An insertion piece formed on the other side with respect to the mouth is formed so as to be insertable, and formed on both the tongue and the front wall, and the insertion piece is inserted into the insertion opening when the tongue grid is closed. It further includes engaging portions that engage with each other in the process of being inserted.

  In the tan grid type package according to the present invention, when the insertion port is provided on the front wall of the case body, the insertion piece is provided on the tongue portion of the tan grid, and when the insertion port is provided on the tongue portion of the tan grid. An insertion piece is provided on the front wall of the case body.

  According to the tan grid type package according to the present invention, the engagement portions formed on both the front wall and the tongue portion of the case body are engaged with each other in the process of inserting the insertion piece into the insertion port when the tan grid is closed. Therefore, it is possible to prevent the insertion piece from inadvertently coming out of the insertion opening. Therefore, the lid closing property of the tan grid type package can be improved as compared with the conventional case. The engaging portion may be configured by a combination of a locking piece provided on the front wall side and a locking piece provided on the tongue portion side. When closing the tongue grid, the locking piece provided on the front wall side of the case body and the locking piece provided on the tongue side are locked to each other so that they are locked together, and the insertion piece is inaccessible from the insertion port. It is possible to suitably suppress the escape.

  In the tan grid type package, at least one of a boundary portion between the lid portion and the rear edge of the opening surface and a boundary portion between the lid portion and the tongue portion may be a round corner. Moreover, the dimension of the width direction along the rear edge of the said opening surface among the said case main body may be large compared with the dimension of the height direction orthogonal to this width direction and along the said front wall. In the former case, it can be said that the blank that is folded to form the package tends to have a greater restoring force to return to the original shape, and the insertion piece can be easily pulled out from the insertion opening. In the latter case, it is difficult to sufficiently secure the dimension between the insertion port (or insertion piece) formed on the front wall of the case body and the upper end of the front wall. In this case, it can be said that the insertion piece is easily pulled out from the insertion port. . Even under such a condition that the lid closing property is likely to deteriorate, according to the package of the present invention, when the tan grid is closed, the engagement portions that engage with each other in the process of being inserted into the insertion port are provided. Since it did in this way, it can suppress that an insertion piece pulls out from an insertion port carelessly.

  In addition, although the to-be-contained object accommodated in a tan grid type package is not specifically limited, For example, a tobacco product can be illustrated suitably as a to-be-contained object. Examples of tobacco products include cigarettes (filter cigarettes, double-cut cigarettes (no filter)), cigars (cigars), electronic cigarettes, chewing tobacco, snuff tobacco, and the like. Further, the tan grid type package may be a package containing, for example, confectionery, gum or the like.

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

  According to the present invention, it is possible to improve the lid closing property in the tan grid type package as compared with the conventional case.

An object to be accommodated in a package to which the present invention is applied is not limited to a specific object, but in this embodiment, a case where a cigarette is accommodated in a package will be described as an example.

<First Embodiment>
FIG.1 and FIG.2 is a perspective view of the package 1 which concerns on 1st Embodiment, and has shown the state which looked at the package 1 from the front right diagonal side. The package 1 includes a case body 2 and a tan grid 3. The case body 2 has an upper surface opened. Reference numeral 20 denotes an opening formed at the upper end of the case body 2. The tan grid 3 is connected to the rear edge of the opening surface 20 of the case body 2 and is a lid member that opens and closes the opening surface 20. The tan grid 3 is closed in the state shown in FIG. 1, and the tan grid 3 is opened in the state shown in FIG. The package 1 has a so-called clutch bag shape, and can be said to be a clutch bag type package.

  The case main body 2 is a box having a substantially rectangular parallelepiped shape, and a cigarette package (hereinafter referred to as “inner pack”) 4 is accommodated therein as shown in FIG. The inner pack 4 is obtained by wrapping a bundle of cigarettes (not shown) with an inner packaging material 5. The inner packaging material 5 is, for example, a sheet-like aluminum vapor-deposited paper having a rectangular shape, and is formed to include a paper base material and an aluminum film vapor-deposited on the surface thereof. 3a and 5b shown in FIG. 3 are a pair of trapezoidal side flaps formed by overlapping the outer peripheral edges of the inner packaging material 5 and folding them. In the present embodiment, the cigarette bundle is wrapped with the inner packaging material 5 so that the side flaps 5a and 5b face the circumferential surface of the cigarette instead of the end in the longitudinal direction. According to this, when the consumer takes out the cigarette, the end of the cigarette can be hardly caught on the inner packaging material 5. In addition, the chain line shown in FIG. 3 represents a separation line. A consumer who has purchased the package 1 containing the inner pack 4 picks and pulls the side flap 5a on the near side of the inner pack 4 and separates it at the separation line to expose the cigarette to the outside of the inner packaging material 5. be able to.

  The case 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 the outer shape is defined by these. The front wall 21 and the rear wall 22 have the same shape and are arranged to face each other. The front wall 21 and the rear wall 22 are connected to each other by a left side wall 23, a right side wall 24, and a bottom wall 25. Here, the edge 26a located at the boundary between the front wall 21 and the bottom wall 25 and the edge 26b located at the boundary between the rear wall 22 and the bottom wall 25 are round corners (round edges) having a round shape. Yes.

  Further, the front wall 21 of the case body 2 is provided with a slit-like insertion opening 27. The insertion opening 27 is disposed above the center of the front wall 21 in the height direction, that is, at a portion near the opening surface 20. Here, FIG. 1 and FIG. 2 show the front, rear, top, bottom, left and right directions in the package 1. In addition, the up-down direction, the left-right direction, and the front-back direction shown in the figure correspond to the height direction, the width direction, and the depth direction of the package 1 (case body 2), respectively. As shown in FIGS. 1 and 2, the insertion opening 27 extends along the width direction of the front wall 21. The width direction of the package 1 (case body 2) is a dimension in the direction along the rear edge of the opening surface 20. Further, the height direction of the package 1 (case body 2) is a dimension in a direction perpendicular to the width direction and along the front wall 21.

  The tan grid 3 is connected to the rear wall 22 of the case body 2 with the upper edge of the case body 2 as a folding line, that is, a self hinge. The tongue grid 3 includes a lid 31 (lid portion) and a tongue 32 (tongue portion) from the rear wall 22 side. The lid 31 and the tongue 32 are connected via a folding line. In other words, the lid 31 and the tongue 32 divide the tan grid 3 with the folding line as a boundary. Hereinafter, the boundary portion between the rear wall 22 and the lid 31 is referred to as a lid folding portion 33, and the boundary portion between the lid 31 and the tongue 32 is referred to as a tongue folding portion 34. In the present embodiment, the lid folding part 33 and the tongue folding part 34 are both round corners having a round shape.

  The lid 31 has a shape and a size corresponding to the opening surface 20 of the case body 2, and is a lid member that can cover the opening surface 20 so as to be freely opened and closed by being connected to the rear edge of the opening surface 20. It is. The tongue 32 has the same width as the lid 31 and once extends, and then the width gradually decreases. An insertion piece 32 a is formed on the distal end side of the tongue 32 so as to protrude. The width of the insertion piece 32 a is slightly smaller than the insertion opening 27 provided in the front wall 21 of the case body 2.

  As shown in FIG. 1, when the tongue grid 3 is closed, the tongue 32 overlaps with the front wall 21 of the case body 2, and the insertion piece 32 a of the tongue 32 is inserted into the insertion opening 27. As a result, the lid 31 closes the opening surface 20 of the case body 2, and access to the cigarette that is an object to be accommodated in the package 1 is restricted.

  By the way, as shown in FIG.1 and FIG.2, the package 1 which concerns on this embodiment becomes a specification which accommodates the inner pack 4 in the case main body 2 so that the longitudinal direction of a cigarette corresponds to the width direction of the package 1. FIG. Yes. Therefore, the package 1 (case body 2) has a width dimension larger than a height dimension. Although not shown in FIGS. 1 and 2, the case body 2 is usually printed with characters, designs, photographs, and the like for advertising, advertising, and other purposes. In particular, since the front wall 21 of the case body 2 is more easily noticed by consumers compared to other surfaces, there is a demand for securing a larger area as a printing space for characters, pictures, and the like on the front wall 21. .

  Here, since the package 1 is a tan grid type package, the information display space for advertisements, advertisements, and the like on the front wall 21 of the case body 2 is located below the insertion opening 27. This is because the upper portion of the insertion opening 27 in the front wall 21 is hidden under the tongue 32 when the tongue grid 3 is closed. Therefore, from the viewpoint of securing more information display space on the front wall 21 of the case body 2, the insertion opening 27 must be provided at an upper position of the front wall 21, that is, at a location relatively close to the opening surface 20. Many. Also in the package 1 of the present embodiment, the insertion opening 27 is provided at a position on the upper end side (that is, the opening surface 20 side) from the center in the height direction of the front wall 21.

  Furthermore, the package 1 according to the present embodiment stores the inner pack 4 so that the longitudinal direction of the cigarette matches the width direction of the case body 2, so that the longitudinal direction of the cigarette matches the height direction of the case body 2. Compared to the case, the height dimension of the front wall 21 itself becomes smaller. Then, the restoring force of the blank generated in the lid folding part 33 and the tongue folding part 34, more specifically, the restoring force to return to the original shape before the blank is folded, acts on the tan grid 3, The insertion piece 32a is easily pulled out from the insertion opening 27. That is, a situation in which the tan grid 3 opens carelessly easily occurs.

  Therefore, the package 1 according to the present embodiment is provided with a lock structure 6 for suppressing the above problems and improving the lid closing. The lock structure 6 is formed by an engaging portion formed on each of the tongue 32 and the front wall 21, and prevents the insertion piece 32 a from coming out of the insertion opening 27 by the engagement between the engagement portions. is there.

  The lock structure 6 is configured by a combination of a locking tongue piece 28 (locking piece) provided on the front wall 21 of the case body 2 and a folded piece 35 (locking piece) provided inside the tongue 32. ing. The locking tongue piece 28 is a rectangular tongue piece protruding from the upper edge of the front wall 21. In the example shown in FIGS. 1 and 2, locking tongue pieces 28 are provided at two locations on the upper edge of the front wall 21.

  The folded piece 35 is formed by folding the front end side of the tongue 32 and partially adhering both end sides of the folded portion to the inner surface of the opposing tongue 32. The folded piece 35 in the present embodiment is formed on both sides of the insertion piece 32a. Of each folded piece 35, a portion (hereinafter referred to as “flap engaging portion”) 35 a corresponding to the locking tongue piece 28 provided on the front wall 21 in the width direction of the package 1 is bonded to the inner surface of the tongue 32. First, both end portions are bonded to the inner surface of the tongue 32. As a result, a predetermined gap is formed between the flap engaging portion 35a of the folded piece 35 and the inner surface of the tongue 32 so that the locking tongue piece 28 is sandwiched when the tongue grid 3 is closed. The package 1 of this embodiment includes two pairs of folded pieces 35 and locking tongue pieces 28 that are engaged with each other when the tongue grid 3 is closed, but the number thereof is not particularly limited.

  Next, with reference to FIG. 4, the operation state at the time of closing the package 1 is demonstrated. FIG. 4 shows each state from the opened state to the closed tan grid 3 of the package 1. The first to fourth states are shown from the left to the right. The cross section of the package 1 shown in FIG. 4 corresponds to the AA cross section of FIG.

  The first state shown in FIG. 4 shows a state where the package 1 is opened. In the first state, the locking tongue piece 28 protrudes upward from the upper edge of the front wall 21.

  Next, the handler performs a closing operation of the tan grid 3 in order to close the package 1. When the closing operation of the tongue grid 3 is started, the outer surface 35b of the folded piece 35 provided on the tongue 32 is brought into a second state in which the outer surface 35b contacts the inner surface 28a of the locking tongue piece 28 provided on the upper edge of the front wall 21. And migrate. The inner surface 28 a of the locking tongue piece 28 is a surface of the locking tongue piece 28 that faces the opening surface 20 in the case body 2.

  In the second state, the outer surface 35 b of the folded piece 35 is pressed against the inner surface 28 a of the locking tongue piece 28 with the closing operation of the tongue grid 3. Thereby, the attitude | position of the latching tongue piece 28 inclines toward the case main body 2 frontward from the connection base end part with the upper edge of the front wall 21 as a boundary. In this manner, when the insertion piece 32a of the tongue 32 is inserted into the insertion opening 27 while pressing the locking tongue piece 28 toward the front wall 21 by the folded piece 35, the third state is obtained. In the third state, the pressing degree of the locking tongue piece 28 by the folded piece 35 is further advanced as compared to the second state.

  When the insertion amount (length) of the insertion piece 32a with respect to the insertion opening 27 increases, the outer surface 35b of the folded piece 35 gets over the inner surface 28a of the locking tongue piece 28, so that the fourth state is obtained. That is, the folding piece 35 and the locking tongue piece 28 engage with each other in the process in which the insertion piece 32 a is inserted into the insertion opening 27. As described above, in the fourth state, the folded piece 35 and the locking tongue piece 28 are locked with each other, and the package 1 is closed by the lid 31 closing the opening surface 20. It becomes a state. Further, when the locking tongue piece 28 gets over the folded piece 35, that is, when the folded piece 35 and the locked tongue piece 28 are locked to each other, the locked tongue piece 28 is folded back. A sound is produced by being played by the piece 35. As described above, the sound generated when the folded piece 35 and the locking tongue piece 28 are locked to each other enables the user to confirm that the package 1 is surely closed. The feeling of use can be improved.

  According to the package 1 according to the present embodiment, the lid folding portion 33 between the case body 2 and the lid 31 and the tongue folding portion 34 between the lid 31 and the tongue 32 in a state where the tan grid 3 is closed. Even if the restoring force (repulsive force) of the blank generated in such a place acts on the tongue grid 3, the folded piece 35 and the locking tongue 28 are locked to each other, so that the insertion piece 32a of the tongue 32 is Pulling out from the insertion opening 27 on the case body 2 side can be suppressed. Therefore, the lid closing property of the tan grid type package 1 can be improved as compared with the conventional case.

  In particular, as in the package 1 according to the present embodiment, when the lid folding portion 33 and the tongue folding portion 34 have a round shape, the restoring force of the blank is larger than that of a square shape. Is big. Further, when the inner pack 4 is accommodated such that the longitudinal direction of the cigarette is along the width direction of the case body 2 as in the package 1, the tongue 32 has a relationship of securing a display space such as a health warning on the front wall 21. The arrangement position of the insertion opening 27 for inserting the insertion piece 32 a tends to be near the upper edge of the front wall 21. Even under such conditions, according to the package 1, the lock structure 6 including the combination of the folded piece 35 and the locking tongue piece 28 that are engaged with each other when the tongue grid 3 is closed is provided. It can suppress that the grid 3 opens carelessly.

Second Embodiment
Next, the package 1A according to the second embodiment will be described. 6 and 7 are perspective views of the package 1A according to the second embodiment. FIG. 8 is a development view of the blank B2 forming the package 1A. Here, the same components as those in the package 1 according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Hereinafter, the package 1A according to the second embodiment will be described focusing on differences from the package 1 according to the first embodiment.

  FIG. 6 shows the package 1A in a state in which the tan grid 3 is closed, and FIG. 7 shows a state in which the tan grid 3 is opened. In the package 1 according to the first embodiment, the insertion opening 27 for inserting the insertion piece 32a of the tongue grid 3 (the tongue 32) is formed by punching the front wall 21, but in the second embodiment, the case main body 2 An insertion band member 29 is provided on the front wall 21.

  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 back onto the front wall 21 from the folding line. Outer band member 29b is connected to the end of inner band member 29a located on the opposite side of the connection end with the upper edge of front wall 21 via a folding line. The outer side band member 29b is overlapped on the inner side band member 29a by being folded back from the folding line with respect to the inner side band member 29a. As shown in FIGS. 6 and 7, the outer band member 29b has a larger dimension in the width direction of the package 1A than the inner band member 29a, and both side end portions 29c are directly bonded to the front wall 21.

  Further, a slit-like insertion opening 27 is opened at the boundary between the inner band member 29a and the outer band member 29b, and the insertion piece 32a of the tongue 32 can be inserted into the insertion opening 27. Yes. More specifically, when the tongue grid 3 is closed, the insertion piece 32a in the tongue 32 is inserted into the insertion opening 27 while being inserted into a gap formed between the inner band member 29a and the outer band member 29b. In this manner, the insertion piece 32 a is inserted into the insertion opening 27, whereby the opening surface 20 of the case body 2 is closed by the lid 31 of the tan grid 3. When the tongue grid 3 is closed, the folded piece 35 and the locking tongue piece 28 are engaged with each other to be locked. Therefore, similarly to the package 1 according to the first embodiment, it is possible to prevent the insertion piece 32a of the tongue 32 from being inadvertently pulled out from the insertion opening 27 on the case body 2 side.

  In the blank B2 shown in FIG. 8, an insertion band inner panel P14 that becomes the inner band member 29a of the insertion band member 29 is connected to the lower end of the front wall panel P1. This insertion band inner panel P14 is connected to an insertion band outer panel P15 which is located on the opposite side of the front wall panel P1 and serves as the outer band member 29b of the insertion band member 29. A folding line is formed between the insertion band inner panel P14 and the insertion band outer panel P15, and an opening R2 is perforated so as to straddle both. In the example shown in FIG. 8, the opening R2 has an elliptical shape, and the long axis position thereof coincides with the position of the folding line. However, the shape of the opening R2 can be changed as appropriate. Furthermore, the width dimension of the insertion band outer panel P15 is larger than the width dimension of the insertion band inner panel P14. The width dimension here is a dimension in the direction corresponding to the width direction in the package 1A after assembly, and is a dimension along the folding line between the insertion band inner panel P14 and the insertion band outer panel P15.

  Also in the blank B2, similarly to the blank B1 described above, the case main body 2 and the tan grid 3 are formed by folding from the folding line indicated by the alternate long and short dash line, and the package 1A as shown in FIG. 6 is obtained. The insertion band inner panel P14 is folded on the outer surface side of the front wall panel P1. Then, the insertion band outer panel P15 is folded from the folding line so as to be superimposed on the insertion band inner panel P14.

  As described above, since the insertion band outer panel P15 has a larger width dimension than the insertion band inner panel P14, both ends of the insertion band outer panel P15 directly overlap the front wall panel P1. In this embodiment, the insertion band member 29 is fixed to the front wall 21 of the case body 2 by adhering portions (both end portions) directly overlapping the front wall panel P1 of the insertion band outer panel P15 to the front wall panel P1. Has been.

  When the package 1A is assembled, the insertion band inner panel P14 and the insertion band outer panel P15 are not bonded to each other. Therefore, a gap is formed between the insertion band inner panel P14 and the insertion band outer panel P15. When closing with the tongue grid 3, the insertion piece 32 a can access the insertion opening 27 using the gap, and the insertion piece 32 a can be inserted into the insertion opening 27. The package 1A shown in FIG. 6 is completed by the above folding molding.

  According to the package 1A configured as described above, the same effects as those of the package 1 according to the first embodiment can be obtained. That is, since the insertion piece 32a of the tongue 32 can be prevented from inadvertently slipping out of the insertion opening 27 on the case body 2 side from the state in which the tongue grid 3 is closed, it is possible to provide the package 1A with excellent lid closure. It is.
