Description

The present invention relates to a box-shaped container and a box-shaped packaged food. For example, a box-shaped container made of a thick paper blank plate and a soft-wrapped food (a food in a state of being packaged in a flexible packaging material) in the box-shaped container. It is related to box-shaped packaged foods that store.

Conventionally, there has been known a box-shaped container in which the lid is lightly locked and a sound is generated when the container is resealed. For example, Patent Documents 1 and 2 propose a hinge lid type carton that opens and closes a lid by bending the boundary between the lid and the container body as a hinge. These cartons are equipped with a locking mechanism that locks the lid to the container body, and when resealed, the lid is locked by the flap and a click sound and vibration are generated. From the click feeling obtained by this, it is possible to realize that the lid is locked (the closing operation is completed). In addition, the same click feeling can be obtained when the lock is released, and it is possible to realize that the lid has been unlocked (opening operation completed).

If the lid is provided with a locking mechanism as described in Patent Documents 1 and 2, mass production of a box-shaped container becomes difficult. For example, when a general pasting machine is used, it becomes difficult to bond the containers during assembly, which leads to an increase in cost and a decrease in productivity. Usually, a hinge lid type carton requires complicated and difficult work not only in its manufacture but also in filling its contents. Therefore, the hurdle to practical use is often high, and if a locking mechanism is provided on the lid, practical use becomes even more difficult. Therefore, it is impossible to fill with a conventional general-purpose filling machine, and it is necessary to design and introduce a special cartner machine.

For example, in the case of the paper box described in Patent Document 1 (FIGS. 1 and 2), when the front plate 1, the back plate 4 and the side plates 3 and 5 are folded, the flaps 11 and 12 provided on the top plate 9 of the lid are folded. One of them protrudes to one side. Therefore, the protruding flaps 11 or 12 become an obstacle, and it becomes difficult to bond the front plate 1, the back plate 4, and the side plates 3 and 5 into a tubular shape. As a result, a special jig or the like for pressing the flaps 11 and 12 is required, and the filling speed of the contents is lowered. Further, since it is necessary to attach a sealing seal or the like to the lid front plate 10 or the like until the first opening is performed, the virginity at the time of initial opening cannot be maintained high.

The packaging container described in Patent Document 2 is the same as the paper box described in Patent Document 1. When the bottom plate 2, the top plate 4 and the side plates 3 and 5 are folded (FIG. 7 and the like), the locking piece 15 provided on the front plate 9 is in a state of protruding to one side. Therefore, the locking piece 15 becomes an obstacle, and it becomes difficult to bond the bottom plate 2, the top plate 4, and the side plates 3 and 5 into a tubular shape. As a result, a special jig or the like for holding the locking piece 15 is required, and the filling speed of the contents is lowered. Further, since it is necessary to attach a sealing seal or the like to the locking plate 10 or the like to seal the seal until the first opening, it is not possible to maintain high virginity at the time of initial opening.

The present invention has been made in view of such a situation, and an object of the present invention is to provide a click feeling at the time of resealing while being easy to manufacture, and a box-shaped container and a box-shaped packaging having high virginity at the time of initial opening.

1 to 3 show the appearance of the main parts of the box-shaped containers 101, 102, 103 according to the first to third embodiments in an opened state. The box-shaped containers 101 to 103 are hinge-lid-type cartons composed of a lid P1 and a container body P2, and have a rectangular parallelepiped shape in an unopened state. The boundary between the lid P1 and the container body P2 is formed by a cutting line M1, M2, M3 that can be broken by pressing and a bending line X1 that can be bent as a hinge, and the cutting line M1 is formed when the container is opened. The lid P1 and the container body P2 are integrated until they are broken by ~ M3. Therefore, the box-shaped containers 101 to 103 retain their virginity until the initial opening. Since the box-shaped containers 101 to 103 shown in FIGS. 1 to 3 are in the opened state, the cut lines M1 to M3 show the state after breaking.

The cut lines M1 to M3 are made of intermittent cuts, and when they are broken by pressing, the lid P1 can be opened and closed by bending with the bending line X1 as a hinge, as shown by the arrow mR. The box-shaped containers 101 to 103 are provided with a locking plate 10 having an opening 10a in the lid P1 as a locking mechanism for locking the lid P1 to the container body P2, and are locked with the locking plate 10 in the opening 10a. A possible locking flap 3a is provided on the container body P2.

When the lid P1 partially separated from the container body P2 due to the breakage at the cutting lines M1 to M3 is closed by rotation around the bending line X1, the locking plate 10 becomes the locking flap 3a within the opening 10a. Locked. Since the locking flap 3a can be bent using the bending line X2 as a hinge, when the lid P1 is resealed, the locking plate 10 provided on the lid P1 is locked by the locking flap 3a, and a clicking sound and vibration are generated. To do. From the click feeling obtained by this, it is possible to realize that the lid P1 is locked (the closing operation is completed). Further, the same click feeling can be obtained when the lock is released, and it is possible to realize that the lid P1 has been unlocked (opening operation completed).

It is possible to lock the opening tab 1c with only one of the notch 3b and the opening 3c.

The box-shaped containers 101 to 103 are intended for use as, for example, a packaging container (secondary packaging container such as a paper container or a clear case) for storing the contents of flexible packaging (primary packaging), and are box-shaped. Inside the containers 101 to 103, a storage space S for storing the contents is provided. The contents include foods (for example, beverages such as stick coffee; seasonings such as stew base; confectionery such as chocolate), cosmetics (for example, make-up cosmetics such as lipstick and manicure), and other articles. (For example, daily necessities having a long shape such as cotton sticks, straws, chopsticks, writing utensils, etc.), etc., but here, stick-shaped soft-packaged foods (stick coffee, etc.) containing powdered beverages (instant coffee, etc.) Packaged food) is assumed as the content. Then, the box-shaped packaged food is formed by storing one or a plurality of flexible packaged foods in the storage space S. Therefore, applications of the box-shaped containers 101 to 103 include food cases (confectionery boxes, etc.), cosmetic cases, sales promotion cases, and the like.

FIG. 4 shows an opened state of the box-shaped packaged food 303 according to the third embodiment as viewed from the side surface side. The box-shaped packaged food 303 has a configuration including a box-shaped container 103 and a flexible packaged food F stored in the box-shaped container 103, and the flexible packaged food F is a stick-shaped powdered beverage (instant coffee or the like). It is configured in a state of being wrapped in the flexible packaging material of. In the unopened box-shaped packaged food 303, the flexible packaged food F housed in the storage space S of the box-shaped container 103 is in a sealed state. When the box-shaped container 103 is broken along the cut-out lines M1 to M3, the lid P1 rotates about the bending line X1 from the closed state (dashed-dotted line) to the open state (solid line) (arrow mR), and the flexible packaged food. F can be taken out. Even when the box-shaped packaged foods are composed of the box-shaped containers 101 and 102, the opened state is the same as that of the box-shaped packaged foods 303.

The development views of FIGS. 5 to 7 show the blank plates 201, 202, and 203 constituting the box-shaped containers 101, 102, and 103, respectively. The box-shaped containers 101 to 103 are formed by bending one blank plate 201 to 203. Further, the blank plates 201 to 203 are formed by punching a plate-shaped sheet material as shown in the developed views (FIGS. 5 to 7).

Examples of the sheet material constituting the blank plates 201 to 203 include thick paper (cardboard and the like) and resin plates (transparent or opaque resin plates made of resins such as polyethylene terephthalate and polypropylene). When the box-shaped containers 101 to 103 are configured as a resin clear case (transparent plastic case), the contents can be easily visually recognized, and information is displayed on both the box-shaped containers 101 to 103 and the contents (product information, etc.). Display) is possible. Regarding the material, the individual wrapping is the same as that of the blank plates 2001 to 203, and a material (paper, resin, etc.) can be used as required. However, here, a resin film is assumed as the flexible packaging material.

As shown in FIGS. 5 to 7, the blank plates 201 to 203 are front plate 1; back plate 2; inner surface plate 3; top plate 4; bottom plate 5; side plates 6, 7; glue margin plates 8, 9; The locking plate 10; the connecting plate 11 and the like.

A pair of side plates 6 and 7 are located on the left and right sides of. The top plate 4 is located above the front plate 1, the back plate 2 and the side plates 6 and 7 (top surface side), and the bottom plate 5 is below the front plate 1, the back plate 2 and the side plates 6 and 7 (on the top surface side). It is located on the bottom side). Further, the inner surface plate 3 is fixed at a position inside the front plate 1, the glue margin plate 8 is fixed at a position inside the side plate 6, and the glue margin plate 9 is fixed at a position inside the side plate 7. It is fixed.

The top surface side portion of the front plate 1 is made of a glue margin plate 1a, and the bottom surface side portion of the front plate 1 is made of a glue margin plate 1b. A connecting plate 11 and a locking plate 10 are provided in order on the top surface side of the glue margin plate 1a. Half-cut perforations N1 and N2 are formed on the adhesive-coated surfaces of the glue margin plates 1a and 1b, respectively, and the adhesive strength can be adjusted by the number of perforations. Further, in the side plates 6 and 7, flaps 6a, 6b; 7a, 7b are provided on the top surface side and the bottom surface side, respectively. In the blank plate 203 (FIG. 7), half-cut perforations N3 and N4 are further formed on the adhesive-coated surfaces of the flaps 6a and 7a, and the adhesive strength can be adjusted by the number of perforations. There is.

The blank plates 201 to 203 are formed with cutting lines M1 to M4 for breaking and bending lines K1 to K16, X1 and X2 for bending. The cut lines M1 to M4 have a linear processing structure in which cuts are arranged intermittently, and can be broken cleanly by pressing with a finger or the like, but have a strength that does not break even if an unintended force is applied. .. Its strength can be adjusted by the length, shape, depth, etc. of the notch. Further, although the cut lines M1 to M4 are formed by a combination of the cut portion and the blade stopper portion, for example, the cut lines M1 to M4 may be formed by ordinary perforations or zippers.

The fold lines (fold lines) K1 to K16, X1 and X2 are linear processed structures whose strength is weakened in order to easily form creases. For example, push lines (concave grooves, etc.) and lead lines (concave grooves, etc.) It is composed of perforations (intermittent arrangement of cuts, etc.), etc. (alternate arrangement of cuts and push rules, etc.). The folding lines X1 and X2 are formed of lead ruled lines so as to enable proper bending as a hinge, but the folding lines X1 and X2 are formed by other linear processing according to the material of the blank plates 201 to 203. Of course, it is also possible to adopt a structure.

In the blank plates 201 to 203, the cut lines M2 are formed on the front plate 1, and the cut lines M1 and M3 are formed on the pair of side plates 6 and 7 located on the left and right sides of the front plate 1, respectively. Further, the bending line X1 is formed on the back plate 2, and the bending line X2 is formed on the inner surface plate 3. The glue margin plate 8 of the blank plates 201 and 202 is formed with a cut line M4 at a position overlapping the cut line M1 in the box-shaped containers 101 and 102.

In the blank plates 201 and 202, the folding lines K1 to K4 and K7 to K15 are formed of push-rules to form creases. Further, the fold lines K5 and K6 are composed of reed rules for forming creases, and the fold lines K16 are composed of two notches for forming creases. In the blank plate 203, the folding lines K1 to K4 and K11 to K14 are made of push-rules to form creases. The fold lines K5 to K9 and K15 are made up of reed rules to form creases, and the fold lines K16 are made up of two notches to form creases.

In the box-shaped containers 101 to 103, the lid P1 is a top plate rather than the boundary formed by the cutting lines M1 to M3 and the bending line X1 of the front plate 1, the back plate 2, and the side plates 6 and 7. It is composed of a part located on the 4th side. On the other hand, the container body P2 is located on the bottom plate 5 side of the bottom plate 5, the boundary formed by the cut lines M1 to M3 and the bending line X1 of the front plate 1, the back plate 2, and the side plates 6 and 7. It is composed of a portion and an inner surface plate 3. A locking flap 3a is formed on the upper end of the inner surface plate 3, and the locking plate 10 is fixed to the inside of the front plate 1 constituting the lid P1 so as not to protrude from the front plate 1. There is. As described above, the locking plate 10 has an opening 10a, and the locking flap 3a can be locked with the locking plate 10 within the opening 10a.

The unopened box-shaped containers 101 to 103 are assembled by bending the blank plates 201 to 203 along the bending lines K1 to K16, X1 and X2 as follows. First, using a pasting machine, the blank plates 201 to 203 are folded (a state in which a tubular rectangular parallelepiped is folded), and the side plates 6 and 7 and the glue margin plate 8 are placed on the front plate 1 and the back plate 2. , 9 is three-dimensionally tubularized so that it stands upright, and then the contents are filled using a filling machine. FIG. 8 shows the assembling state of the box-shaped containers 101 and 102 from the back plate 2 side, and FIG. 9 shows the assembling state of the box-shaped container 103 from the back plate 2 side. In FIGS. 8 and 9, (A) shows the folded state of the blank plates 201 to 203, and (B) shows the tubular state of the blank plates 201 to 203.

The folding and tubularization of the blank plates 201 to 203 will be described in more detail. An adhesive (for example, a hot melt adhesive) is applied to the glue margin plates 8 and 9 and the locking plate 10 (FIGS. 5 to 7). The locking plate 10 and the connecting plate 11 are bent at the bending line K15 so that the connecting plate 11 overlaps the glue margin plate 1a and the locking plate 10 overlaps the front plate 1 on the glue margin plate 1a side of the cutting line M2. Then, the blank plates 201 to 203 are bent along the bending lines K1 to K6 so that the glue margin plates 8 and 9 are in close contact with the insides of the side plates 6 and 7, respectively, to complete the bonding. As a result, a folded blank plate 201-203 is obtained in which the locking plate 10 is attached to the inside of the front plate 1 and the glue margin plates 8 and 9 are attached to the inside of the side plates 6 and 7, respectively. ((A) in FIGS. 8 and 9).

Next, the blank plates 201 to 203 are three-dimensionally tubularized so that the side plates 6 and 7 and the glue margin plates 8 and 9 stand upright with respect to the front plate 1 and the back plate 2 (FIGS. 8 and 9). (B)). An adhesive (for example, a hot melt adhesive) is applied to the glue margin plates 1a and 1b, and the flaps 6a and 7a; the glue margin plates 1a and the top plate 4 are attached to the blank plates 201 and 202 along the bending lines K7 to K10, respectively. In the folding and blank plate 203, the flaps 6a and 7a; the glue margin plate 1a and the top plate 4 are bent along the bending lines K7 to K9 and X1, respectively. After the top plate 4 is attached to the glue margin plate 1a, the accommodation space S is filled with the contents (flexible packaged food), and then the flaps 6b and 7b along the bending lines K11 to K14; the glue margin plate 1b and the bottom plate. Each of 5 is bent, and the bottom plate 5 is attached to the glue margin plate 1b. As a result, the storage space S in which the contents are housed is in a sealed state, and the box-shaped packaged food is stored and transported in the sealed state (unopened state). In the box-shaped packaged food 303 shown in FIG. 4, the closed state (two-dot chain line) of the lid P1 indicates the sealed state of the storage space S.

In the unopened box-shaped containers 101 to 103 in which the storage space S is sealed, the front plate 1 and the back plate 2 are located so as to face each other, and a pair of the front plate 1 and the back plate 2 located on the left and right sides of the front plate 1 and the back plate 2. The side plates 6 and 7 of the above are located so as to face each other. Further, the top plate 4 located above the front plate 1, the back plate 2 and the side plates 6 and 7 and the bottom plate 5 located below the front plate 1, the back plate 2 and the side plates 6 and 7 face each other. It is located to do. In the box-shaped containers 101 to 103, the virginity is maintained in this state until the initial opening.

In the folded blank plates 201 to 203, as shown in FIGS. 8 and 9 (A), the locking plate 10 is fixed so as not to protrude from the front plate 1. Since the locking plate 10 is positioned so as not to protrude from the front plate 1, the locking plate 10 does not get in the way even when a general pasting machine or filling machine is used, and the blank plates 201 to 203 are three-dimensional. It is possible to easily perform laminating (roll-in pasting, etc.) for forming a tubular shape. As a result, a special jig or a special car toner machine for pressing the locking plate 10 is not required, and for example, filling using a horizontal car toner (horizontal end load) is possible. Therefore, the filling speed of the contents is not lowered, and the amount of paper waste generated when the blank plates 201 to 203 are produced is small. Therefore, the blank plate 201 that can be folded ((A) in FIGS. 8 and 9) can be folded. ~ 203 is suitable for high-speed mass production at low cost. Further, the locking mechanism can be easily made compact only by bending the blank plates 201 to 203 along the bending line K15, which is also suitable for mass production.

When opening the box-shaped containers 101 to 103, the cutting lines M1 to M3 are broken by pressing. As described above, the lid P1 partially separated from the container body P2 due to the breakage at the cutting lines M1 to M3 is formed around the bending line X1 as shown by the arrow mR in FIGS. 1 to 3. It can be opened and closed by movement. When the lid P1 is closed, the locking plate 10 is locked to the locking flap 3a in the opening 10a to be in a light locked state, and when the lid P1 is opened, the locking plate 10 is unlocked from the locking flap 3a. It will be unlocked. A clicking sound and vibration are generated when the lid P1 is locked and unlocked, and the completion of the opening / closing operation of the lid P1 can be known from the click feeling obtained thereby.

According to the box-shaped containers 101 to 103 (FIGS. 1 to 3), as described above, the lid P1 and the container body P2 are integrated until the cut lines M1 to M3 are broken, so that the sealing seal is provided. It is not necessary to attach it to the front plate 1 or the like to seal or seal it, and high virginity is maintained until the initial opening. Further, when the lid P1 is closed by rotation about the bending line X1, the locking plate 10 is locked to the locking flap 3a, and the locking makes a clicking sound and vibration, resulting in a click feeling. Therefore, it is possible to realize that the lid P1 is locked. Since the locking is performed within the opening 10a of the locking plate 10, the locking mechanism can be made compact, and the box-shaped containers 101 to 103 can be easily manufactured, and a general pasting machine or filling machine can be used. Can be manufactured using. Therefore, it is possible to realize box-shaped containers 101 to 103 and box-shaped packaged foods 303, which are easy to manufacture but have a click feeling at the time of resealing and have high virginity at the time of initial opening.

In the box-shaped container 102 (FIG. 2), the cut line M2 in the front plate 1 has a curved portion that is convex toward the bottom plate 5, and the container body P2 to the lid P1 are on the top plate 4 side of the curved portion. An opening tab 1c that is pressed to separate the opening tab 1c is formed. As shown in FIG. 6, an arc-shaped emboss 1e is formed on the opening tab 1c. As described above, by providing the opening tab 1c protruding in a curved shape on the lid P1 or further embossing it, it is possible to easily perform the initial opening by pressing.

Further, in the box-shaped container 102, a notch 3b and an opening 3c are formed in the inner surface plate 3 as a locking portion that can be locked with the opening tab 1c (FIGS. 2 and 6). By providing the locking portion consisting of at least one of the notch 3b and the opening 3c in this way, when the lid P1 is closed, the locking plate 10 is locked to the locking flap 3a within the opening 10a. Further, since the opening tab 1c is locked to the inner surface plate 3 by the notch 3b and the opening 3c, the resealing property is further improved. That is, there are two engagements: a first locking mechanism including a locking plate 10 having an opening 10a and a locking flap 3a, and a second locking mechanism consisting of an opening tab 1c, a notch 3b and an opening 3c. Double lock by the stop mechanism is possible.
