Description

  The present invention relates to a carton (paper box) that stores powder detergents, wheat flour, and other granular confectionery, etc., and a carton having moisture resistance and a structure that can be easily opened and a reseal function.

  A carton that stores powdered detergent, flour, and other granular confectionery such as garlic, konpeito, etc. The opportunity to use the contents without opening them all at once and opening and closing them many times after opening In many cases, in addition to moisture-proofing before opening and easy opening, a resealing function capable of holding the lid closed again after opening is required. For example, cartons of various forms have been used as containers for powder detergents in the past, but in the case of cartons that store so-called compact type powder detergents that are used with measuring spoons that have become common in recent years. Requires that the lid be wide open so that the powder can be easily scooped with a measuring spoon and can be resealed after use. Cartons satisfying such requirements include those in which the main body and the lid are separated and those in which a lid that can be opened and closed is provided integrally with the main body. An example of the former is the container shown in Patent Document 1. The container described in this utility model publication is a container in which an opening provided at at least one end of a cylindrical body of a polygonal columnar container is sealed with a sealing material, and an edge of the cylindrical body on the opening side. In addition, the folded piece is continuously provided through a half-cut line provided from the outside, the folded piece is folded inside the cylindrical body, and the folded piece is bonded to the inner surface of the cylindrical body. It is a container characterized. This container can secure moisture resistance by sealing the opening with a sealing material, so it is suitable as a powder detergent container, but a sealing process is necessary, and a sealing material is separately prepared. This is disadvantageous in terms of cost. Further, since the lid is separated from the main body, there are problems in terms of usability and cost.

  As an example of a carton in which a lid and a main body are integrated, a paper box such as a powder detergent disclosed in Patent Document 2 can be cited. As described in the claims, the paper box has a flat rectangular parallelepiped lid that is composed of a lid plate and four lid side plates, an appropriate bottom plate group, and four barrels. It is a paper box such as a hinge lid type powder detergent, which is connected to the rear surface side of a rectangular parallelepiped box body consisting of a side plate, and has an appropriate opening on the inner surface side of the front lid side plate of the lid body. A center part of the upper side of the front torso side plate, which is provided with a connection cutout, is connected to the upper side of the front torso side plate of the box body via a crease line, In addition, a paper box for a powder detergent or the like, in which a closing lid locking piece is provided via a valley fold line.

  This paper box is connected to the box body and the lid, and can be opened and closed in a hinged manner, and it is locked by the lid locking piece when the lid is closed. However, there is a problem in terms of cost due to the necessity of a sealing paper and a sealing process for ensuring moisture resistance and the fact that the box body and the lid are made of separate blanks.

Furthermore, in order to solve this problem, a paper box such as a powder detergent disclosed in Patent Document 3 has a structure that can be assembled from a single blank by using a part of the blank as a sealing plate. In addition, there is no need for a separate sealing process, and since the opening method is a tape cut method using two horizontal perforations, there is a gap corresponding to the width of the tape inevitably removed when resealed. Therefore, it is necessary to provide a partition structure for preventing the lid from falling, and accordingly, an extra carton base material is required. Generally, this problem is inherent in the case of a horizontal cut method using a cut tape. In addition, in the case of the horizontal cut method, since the perforation for opening exists in front of the product, there are many restrictions in terms of design. There is a method of embedding a plastic tape under the face plate to prevent the perforation from being seen, but this is disadvantageous in terms of cost due to the extra tape material cost and the complexity of the process. Met. Therefore, a carton having a structure that replaces the horizontal cut method using perforations, which is currently mainstream, has been awaited.

  The present invention has been made in order to solve the above-described conventional problems, and is an easy-to-use carton having both moisture resistance and easy opening, and further having a resealing function. The problem is to supply at low cost by designing so that a carton excellent in design with no perforation for opening can be made from a single blank.

  As a means for solving the above-mentioned problems, the invention according to claim 1 is a rectangular parallelepiped carton assembled from a single blank of paperboard laminated with a moisture-proof resin layer, and includes a front surface, a top surface, and a back surface. The top surface is composed of a top plate and an inner lid, and the top plate has a top plate opening defined by two top plate perforations. The inner lid has an inner lid opening portion defined by a U-shaped opening surface half-cut line provided from the surface side inside the top plate opening portion, and the opening surface half-cut line. An opening back half-cut line provided from the back side that is attached to the inside at regular intervals, and the back surface of the top plate and the surface of the inner lid are formed by the perforation on the top plate and the half of the opening. Bonded at the part other than the two band-like parts sandwiched by the cut line The back surface is composed of a back outer plate and a back inner plate, and the back outer plate is formed by a V-shaped opening flap perforation continuous with the top plate perforation, and an opening flap of the opening flap The opening flap has a resealing hook formed by a cut line; and the back inner plate has a notch that can be fitted to the resealing hook after opening. And the back surface of the said back outer plate and the surface of the said back inner plate are the cartons with a reseal function characterized by adhere | attaching in parts other than the said opening flap and the said opening tab.

  In the invention according to claim 2, the opening flap perforation provided on the back outer plate includes a basic perforation line in addition to a basic perforation line of a normal perforation and an auxiliary perforation line associated therewith. 2. The guide sewing machine according to claim 1, further comprising a guide sewing line that is at an end opposite to the auxiliary sewing line and guides the cut of the paperboard when opened toward the adjacent auxiliary sewing line. A carton with a sealing function.

  According to a third aspect of the present invention, the back outer plate has an opening tab pulling hole adjacent to the opening tab, and the back inner plate is opened at a position corresponding to the opening tab pulling hole. 3. The carton with a reseal function according to claim 1 or 2, wherein the carton has a tab recess.

  The invention according to claim 4 is the carton with a reseal function according to any one of claims 1 to 3, wherein the inner lid has a small flap.

Since the carton according to the present invention has the characteristics as described above, the carton has the following effects. In other words, a board is formed by using a paperboard laminated with a moisture-proof resin layer, and the perforations, cuts, holes, etc. are all made into a double structure on the surface paperboard, and the intrusion of outside air is blocked. The half-cut line for forming the inner lid opening in the inner lid is divided into the front half-cut line of the opening, the back half-cut line of the opening, and the front and back, and these two are shifted and installed at a fixed interval. It does not require a high degree of moisture-proofing, such as wheat flour, individually packaged, konpeito, etc., but has sufficient moisture-proofing as a container for storing contents that require some degree of moisture-proofing. Yes.

  Moreover, since the carton according to the present invention has a structure assembled from one continuous blank, there is an effect that the material cost and the processing cost can be reduced. In addition, since the opening part is provided on the back and top, it is possible not to provide perforations and other cuts, fold lines, etc. for opening on the front. There are few restrictions and it is possible to freely adopt a design that is highly appealing when products are displayed.

  In addition, the carton according to the present invention is provided with a resealing hook on the opening flap, and a notch is provided at a position corresponding to the resealing hook so that the resealing hook can be hooked. It can be done.

  In addition, regarding the shape of the opening flap perforation, when the shape has an induction perforation line as described in claim 2, a so-called zipper breakage phenomenon that occurs by cutting the perforation in the opening process of assembling blanks into a carton. In addition, it is possible to prevent the phenomenon that the cutting line breaks from the perforation and tears the opening flap, which often occurs when the carton is opened, and has the effect that the opening is smooth and easy, and the resealing can be stably performed. .

  Furthermore, when an opening tab pull-up hole is provided adjacent to the opening tab and an opening tab recess is provided at the corresponding position, the opening tab is easily lifted when opening, and the opening is much smoother and easier. Become.

  Further, when a small flap is provided on the inner lid, there is an effect of reliably preventing leakage of contents such as when the box falls.

The best mode for carrying out a carton with a resealing function according to the present invention will be described below with reference to the drawings.
FIG. 1 is a developed view showing blanks of an embodiment of a carton with a resealing function according to the present invention, and shows a state where a surface (printing surface) of a carton base paper is viewed from above. The carton of the present invention is characterized in that it is assembled from a single blank of a continuous carton base as shown in the figure. This saves material costs and simplifies the manufacturing process.

  As the carton base paper used in the carton of the present invention, a paperboard on which a moisture-proof resin layer is laminated is used. Specifically, coated cardboard and kraft paper are bonded together by extrusion lamination of polyolefin resin adhesive resins such as LLDPE (linear low density polyethylene resin), LDPE (low density polyethylene resin), PP (polypropylene resin), etc. Extruded laminated paper, similarly wax laminated paper in which coated cardboard and kraft paper are bonded with a wax adhesive, PET (polyethylene terephthalate resin), PP, HDPE (high density polyethylene resin) on the surface of the coated cardboard , LDPE, LLDPE, etc. are used.

  Referring to the developed view of FIG. 1, in this embodiment, the front cover 40 is the center, the inner lid 50 is connected via the fold line p, and the back inner plate 60 is connected continuously via the fold line q. On the side, a bottom plate 30 is connected via a fold line o, a back outer plate 20 is connected via a fold line n, and a top plate 10 is further connected via a fold line m.

  At the center of the top plate 10, a top plate opening 13 is provided that is partitioned by two top plate perforations v, and the remaining portions on both sides serve as the top plate edge 12. A flap 11 is provided on both sides of the top plate 10, and the flap 11 is perforated. This perforation is performed for the purpose of improving the adhesion to the side inner plate 21, but is not necessarily required depending on the type of carton base paper or the type of adhesive.

The back outer plate 20 is provided with V-shaped opening flap perforations s formed in a continuous state via the folding line m portion on the two top surface perforations v of the top surface plate. Yes. An opening flap 22 defined by the opening flap perforation s and an opening tab 23 connected to the center via an opening tab folding line w are provided, and the opening flap 22 is formed by a cut line. An arc-shaped reseal hook k is provided. Further, in this drawing, a resealing hook folding line u associated with the resealing hook k and an opening tab pulling hole t are provided adjacent to the bottom of the opening tab 23. These are not essential, but have the effect of facilitating the opening operation and the resealing operation.
Side inner plates 21 are connected to both sides of the rear outer plate 20.

  On both sides of the bottom plate 30, flaps 31 are provided continuously. Similar to the flap 11, the flap 31 is also perforated to improve the adhesion to the side inner plate 21.

The front plate 40 is a portion that is the front of the product. Since the front plate 40 can be free of perforations, fold lines, cut lines, and the like, it is possible to give a printed expression with a free design.
Side outer plates 41 are connected to both sides of the front plate 40. The side inner plate 21 and the side outer plate 41 constitute a side surface of the carton. In the case of this development view, both of these have a width dimension substantially equal to the depth finish dimension of the side surface of the carton, and constitute an almost complete double wall, but this is not always necessary. The width of the inner side plate may be reduced to the extent of the margin, or both may be narrowed and overlapped with the margin at the center of the side. In this case, since the joints can be seen on the side surfaces, it is not preferable in terms of design, but the width of the entire blank can be narrowed, so that the material can be saved.

At the center of the inner lid 50, there is a U-shaped opening surface half-cut line h located inside the two top panel perforations v provided on the top panel 10 and provided from the surface side. A partitioned inner lid opening 53 is provided, and the remaining portion becomes the inner lid edge 52. The U-shaped opening half-cut line h starts from the folding line p and reaches the folding line q. In FIG. 1, the U-shaped opening half-cut line h shares the center of the folding line q and returns to the folding line p. It has the shape of In addition, you may make the part on the folding line q long so that it may protrude a little from two parallel lines of a U-shape. Further, on the back surface of the inner lid 50, there is provided an opening back half-cut line g that follows the opening top half-cut line h with a certain interval. Since the opening surface half-cut line h and the opening back surface half-cut line g are provided at shifted positions, there is no cut through the front and back of the base paper.
Small flaps 51 are continuously provided on both sides of the inner lid 50. The small flap 51 is not necessarily essential, but has an effect of preventing powder leakage when the carton falls down.

  The back inner plate 60 is provided with a notch i for inserting a reseal hook and an opening tab recess j. The opening tab recess j does not require a special process, and may be embossing performed simultaneously with a normal punching process. In this figure, the back inner plate 60 has a shape tapered toward the end in order to facilitate the assembly of the carton blanks.

  The developed view of the carton blanks shown in FIG. 1 shows an example of the embodiment of the present invention, and the present invention is not limited to this. Although not shown, for example, in order from the top, a carton having substantially the same function can be created even in the arrangement of the back outer plate 20, the top plate 10, the front plate 40, the bottom plate 30, the back inner plate 60, and the inner lid 50. Is possible.

Next, a procedure for assembling the carton blanks shown in the development view of FIG. 1 into a carton will be described.
First, the folding lines m, n, o, p, and q are all folded in a mountain, and the top plate 10, the back outer plate 20, the bottom plate 30, the front plate 40, the inner lid 50, and the back inner plate 60 are wound into a cylindrical shape. The back surface of the face plate 10 and the surface of the inner lid 50 are bonded together, and the back surface of the back outer plate 20 and the surface of the back inner plate 60 are bonded together.
At this time, the back surface of the top plate 10 and the surface of the inner lid 50 are bonded to a portion other than the two belt-like portions sandwiched between the opening half-cut line h and the top plate perforation. Further, the back surface of the back outer plate 20 and the front surface of the back inner plate 60 are bonded to portions other than the opening flap 22 and the opening tab 23. In adhering, it is desirable to adhere to a surface rather than a spot-like adhesion from the viewpoint of leakage of contents and ensuring moisture resistance.

As described above, the carton blanks that have been sack pasted are obtained. Next, the description will proceed to a process of opening the carton blanks and filling the contents.
The folded blanks are opened in a cylindrical shape, and first, either the left or right side is molded. The small flap 51, the flap 11, and the flap 31 are bent inward, and then the side inner plate 21 and the side outer plate 41 are bent and bonded in this order. Fill the contents from where the molded side is down and the opposite unshaped side is up. Finally, the unmolded side surfaces are similarly folded in the order of the small flap 51, the flap 11 and the flap 31, the side inner plate 21, and the side outer plate 41, and the filling is completed.

  2 and 3 are perspective views of an embodiment of a carton with a resealing function according to the present invention. FIG. 2 shows an unopened state, and FIG. 3 shows an opened state. An opening flap 22 divided by an opening flap perforation s is provided on the back outer plate 20, and the opening flap perforation s and the opening flap perforation s are continuous with each other by pulling upwards with an opening tab 23 connected thereto. The top plate perforations v on the left and right sides are cut, the opening flap 22 and the top plate opening 13 are opened, and the carton can be opened. At this time, the surface of the back inner plate 60 and the back surface of the back outer plate 20 are bonded at a portion other than the opening flap and the opening tab, and the opening flap and the opening tab are not bonded, so the opening is smooth. In addition, the moisture-proof effect when unopened is also ensured.

  The front surface of the inner lid 50 and the back surface of the top plate 10 are opened since the portions other than the belt-like portion sandwiched between the left and right top plate perforations v and the opening surface half-cut line h are bonded over the entire surface. The sheet is opened by the separation between the papers of the inner lid 50 at the portion sandwiched between the opening surface half-cut line h and the opening back surface half-cut line g inside thereof by force. In FIG. 3, the inter-paper peeling portion x is indicated by shading. In this way, the carton of the present invention is opened by causing the paper separation part x to peel between the paper, so in the unopened state, there is no cut or the like that penetrates the front and back surfaces of the inner lid 50, Moisture resistance during storage is ensured. The width of the inter-paper peeling part x is suitably 1 mm to 5 mm. If it is too wide, resistance at the time of opening becomes strong and smooth opening becomes impossible. On the other hand, if it is too narrow, it is not possible to absorb the variation in position when the half-cut line is processed, and there is a possibility that a through-hole extending from the front to the back may be formed by matching the half-cut line on the front and back.

The unsealing flap 22 is provided with a reseal hook k and a reseal hook fold line u associated therewith. In the present embodiment, the reseal hook k is formed by an arc-shaped cut line, but the shape of the reseal hook is not particularly limited to the arc shape, and may be trapezoidal or tongue-shaped. The arc shape is the easiest to use. After opening, the opening flap 22 can be hooked and resealed by inserting into the notch i shown in FIG. At this time, by providing the fold line u for the reseal hook, the fold line portion is broken when the reseal hook is inserted, and the reseal hook k can be easily inserted into the notch i.
In order to ensure the moisture resistance of the carton, it is desirable that the notch i leave the moisture-proof resin layer without penetrating the back surface of the back inner plate 60.

By providing the opening tab pull-up hole t adjacent to the opening tab 23 in the back outer plate 20, it is easy to cause the opening tab at the time of opening. Further, at this time, a gap is formed under the opening tab by providing the opening tab recess j in a portion corresponding to the position of the opening tab pulling hole t in the back inner plate 60, so that the opening tab 23 is more easily caused. Become.
Further, by providing the opening tab folding line w between the opening flap 22 and the opening tab 23, the opening tab at the time of opening and the operation at the time of reopening after opening are facilitated.

  Next, the perforation will be described. In carrying out the present invention, the openability and resealability can be further improved by devising the shape of the open flap perforation s. 4 to 7 show the perforation shape, and FIG. 4 is a schematic diagram showing the perforation shape of the opening flap portion of the carton with a resealing function according to the present invention. FIG. 5 is a schematic diagram showing a conventional perforation shape. FIG. 6 is an explanatory view showing details of the perforation shape of the opening flap portion of the carton with resealing function according to the present invention, and FIG. 7 is an explanatory view showing the conventional perforation shape.

As shown in FIGS. 5 and 7, the conventional perforation is composed of a basic perforation line 70 and an auxiliary perforation line 71 associated therewith. When opened, the paper perforated from the end of the basic perforation line is formed. The fissure is caught by the auxiliary sewing line, and the opening proceeds by this repetition. When the direction of the force accompanying unsealing coincides with the direction of the basic perforation line as in the case of the top surface perforation v on the top surface plate 10, the unsealing progresses smoothly without any problems even with the conventional perforation, but the unsealing flap 22 When the direction of the basic perforation line 70 is oblique with respect to the force accompanying opening, like the opening flap perforation s for opening the paper, the paper tears in the same upward direction as the direction of the force accompanying opening In some rare cases, a tear that was not perforated progressed.
In order to prevent this phenomenon, if the interval between the perforations is narrowed more than necessary, a so-called zipper break accident in which the perforations are cut at the stage of opening when the contents are filled may occur.

  If the contents are used up once they are opened, tearing the opening will not cause a big problem. However, as in the case of powder detergents and flour cartons that are one of the purposes of the present invention, In the case of an application that will continue to be used later, it is desirable that the opening is formed cleanly so that re-sealing can be ensured. Therefore, in the present invention, as shown in FIG. 6, in addition to the conventional basic sewing machine line 70 and the auxiliary sewing machine line 71, the guide sewing machine line 72 is placed at the end of the basic sewing machine line 70 opposite to the auxiliary sewing machine line. It has been confirmed that this problem can be improved by providing it. By providing the guide sewing line 72, the tear of the paper at the time of opening starts from the tip of the guide sewing line 72, and the adjacent auxiliary sewing line on the extension line of the guide sewing line 72 is surely reached. By repeating this, the opening proceeds smoothly, and as a result, a clean opening is formed.

  Actually, the conventional perforated carton was compared with the improved perforated carton described here, and the zipper breakage occurrence rate and lid tearing rate were evaluated for 50 samples, respectively. The perforated shape had a zipper break rate of 35% and a lid tear rate of 20%, whereas this improved perforated carton had no zipper breaks or lid tears. It was.

The basic perforated line 70 and the auxiliary perforated line 71 constituting the opening flap perforation shown in FIG.
The relative positional relationship of the guide sewing line 72 is preferably as shown in Table 1.

That is, a relationship of 1 mm <b <d is established between the interval b of the basic sewing line 70 and the length d of the basic sewing line, and the angle ∠A formed by the basic sewing line 70 and the auxiliary sewing line 71 is: It is larger than 90 ° and smaller than 180 °, and the angle の B formed by the basic sewing machine line 70 and the induction sewing machine line 72 is larger than 90 ° and smaller than 180 °. Furthermore, the induction sewing machine line The length c of 72 is larger than 0 mm and smaller than 3 mm.
By making the relative relationship of each element constituting the sewing machine line as described above, when opening the opening flap 22, stable opening can be realized, so that the opening flap has a clean shape and is stable even when it is resealed. Sealing is possible. In addition, since it is not necessary to extremely narrow the interval between the perforations, it is possible to prevent a so-called zipper break accident in which the perforations break when they are opened during filling.
The carton with a reseal function according to the present invention will be described below based on examples.

As the carton base paper, basis weight 450 g / m ² of coated cardboard and basis weight 30 g / m ² of an extrusion laminated paper kraft paper was laminated by extrusion lamination method of PE and (Rengo Co. CRPMS) used in Figure 1 The blanks shown were made, assembled and bonded to create a carton as shown in FIG. The finished dimensions of the carton are 90 mm deep, 147 mm wide, and 138 mm high. The shape of the perforation line of the opening flap perforation was as shown in FIGS. 4 and 6, and the dimensions in the detailed view of FIG. 6 were as follows.
Basic sewing machine wire length (d): 5.0 mm
Auxiliary sewing machine wire length (a): 4.0 mm
Guide sewing machine wire length (c) ... 1.0mm
Basic sewing machine wire interval (b): 3.5 mm
Angle between basic sewing machine line and auxiliary sewing machine line (∠A) ・ ・ ・ 135 °
Angle between basic sewing machine line and induction machine line (∠B): 135 °
The carton was evaluated for the rate of occurrence of zipper breakage at the time of opening, moisture resistance when 1.2 kg of powder detergent was enclosed, rate of occurrence of lid tearing at the time of opening, and resealability after opening. For evaluation of moisture resistance, the sample was left in an atmosphere of 40 ° C. and 80% RH for 3 months, and the weight change every month was measured. The resealability was evaluated by a sensory test with 10 monitors. The number of samples was 20 for evaluation of moisture proof and resealability, and 50 for the occurrence rate of zipper breakage and lid breakage at the time of opening.

<Comparative Example 1>
A carton having a horizontal tape cut structure similar to that shown in Patent Document 3 using the same carton base paper as in Example 1 was prepared. The finished dimensions of the carton are the same as in Example 1. This carton was filled with 1.2 kg of powder detergent in the same manner as in Example 1 and evaluated for moisture resistance, openability and resealability. These evaluation results are shown in Table 2. In Table 2, ◯ represents good, Δ represents usable, and x represents unusable.

Thus, in the carton of Example 1, the zipper was not cut at the time of opening, the moisture resistance after filling was good, the lid was not broken at the time of opening, and the resealability was also good.
