Description

Carton Pack {CARTON PACK}

The present invention relates to a carton pack, and more particularly to a carton pack of a gable top type.

A carton pack is a box-shaped container made to hold a liquid beverage such as milk, juice or soft drink. Carton packs are usually manufactured through two processes. The first step is to make blanks from sterile polyethylene coated on both sides of cardboard made of natural pulp. The blank is provided with a fold line, and folded along the fold line to produce a carton pack of the desired shape. The second step is to fold the blank along the fold line and join each joint to make a carton pack of the desired shape.

Carton packs are especially used for milk packaging containers, and there are a gable top type with a triangular roof shape and a brick shape with a brick shape as a whole. Gable top cartons are also called gable top containers. Conventional gable top carton packs contain beverages with a rectangular bottom plate and four body plates extending upward from the bottom plate. The upper part of the carton pack has a pair of roof plates extending upward from a pair of body plates facing each other and folded inclined inwards, and extending upward from a pair of body plates facing each other and folded inwards along a triangular fold line. A pair of gable plates (also called a gable plate and a plywood plate) sandwiched between the roof plates is provided. At this time, the upper part of the pair of roof plates and the upper part of the pair of gable plates are bonded to each other to seal the carton pack. When opening the sealed carton pack, open two roof plates and spread one gable plate, and then press both edges of two roof plates simultaneously to separate the gable plate from the roof plate.

However, when opening such a conventional carton pack, it is often the case that the gable plate is not properly separated from the roof plate. This is because the gable plate and the shingles are sometimes so tightly bonded that they are larger than the separation force between the gutter and the shingles when pressing both edges of the two shingles. In this case, the carton pack is opened by tearing or tearing the joint between the gable plate and the roof plate by hand. This is a very inconvenient task. You may be able to reach the area where the drink comes from. In addition, when the gable-top carton pack is opened in this manner, the inside of the gable plate or the roof plate is not surface-treated, and the beverage is buried in this part, and thus the cleanness cannot be maintained.

An object of the present invention is to provide a carton pack having an opening structure that can be used more conveniently. Another object of the present invention is to provide a carton pack that can be opened more easily since the junction of the opening is separated when opening. Still another object of the present invention is to provide a carton pack in which the open part is cleanly opened to maintain cleanliness. Still another object of the present invention is to provide a carton pack in which a part of the opening is easily opened. Still another object of the present invention is to provide a blank for producing a carton pack in which the junction of the opening is easily and cleanly opened.

First and second fold lines (32,33) and (32a, 33a) which extend from both ends of the lower horizontal fold line 16 and are collected at the lower center in the second and fourth lower plates 28 and 30, respectively. ) Is provided. The first and second lower plates 28 and 30 are formed in the first and second compartments 34 and 34a and 35 by the first and second fold lines 32 and 33 and 32a and 33a, respectively. 35a), third compartments 36 and 36a are provided. Lower ends of the first and third lower plates 27 and 29 may extend slightly lower than lower ends of the second and fourth lower plates 28, 30 and 31.

Referring to FIG. 1A, the first and third upper plates 17 and 19 (hereinafter, referred to as gable plates) among the four upper plates 17, 18, 19, and 20 have the same shape, and the fold lines are the same. The second and fourth top plates 18 and 20 (hereinafter referred to as roof plates) are provided in the same form, and the fold lines are provided in the same manner. It is preferable that the tops of the two roof plates 18, 20 extend slightly above the tops of the two gable plates 17, 19. The two gable plates 17 and 19 respectively have two lower oblique fold lines (37, 38) and (37a, 38a) of the same length, starting from both sides at the bottom and extending obliquely toward the center and upwards. Equipped. Also, the two gable plates 17 and 19 have vertical fold lines 39 and 39a that rise vertically at the point where the two lower oblique fold lines (37, 38) and (37a, 38a) converge. Further, the two gable plates 17 and 19 are inclined at the same angle with the vertical fold lines 39 and 39a interposed between the lower fold lines (37, 38) and (37a, 38a). And raised upper oblique fold lines 40, 41 and 40a, 41a. In addition, the upper portions of the two gable plates 17 and 19 are provided with horizontal fold lines 42 and 42a extending horizontally outward of the upper inclined fold lines 40 and 41 and 40a and 41a.

The two gable plates 17, 19 have a fourth compartment 43, 43a, a fifth compartment 44, 44a, a sixth compartment 45, 45a, a seventh compartment 46, separated by a plurality of fold lines. 46a), eighth compartments 47 and 47a, ninth compartments 48 and 48a, and tenth compartments 49 and 49a are provided.

That is, the part consisting of the sixth and seventh partitions 45 and 46 or the 45a and 46a forms a rectangular vertex at the upper end thereof. However, the present invention is not limited thereto. The upper end of the portion consisting of the sixth and seventh partitions (45, 46) or (45a, 46a) may form a trapezoid (inside the dotted source) as shown in Fig. 1B.

Referring again to FIG. 1A, the two roof plates 18, 20 are horizontal fold lines 50, 50a extending from the horizontal fold lines 42, 42a of the two gable plates 17, 19. It is provided. In addition, the two roof plates 18 and 20 are provided with inclined fold lines 51 and 51a connecting one end of the upper lateral fold line 15 from the upper center portion. Two fold lines 51 and 51a respectively provided on the two roof plates 18 and 20 are inclined toward one gable plate 17 and 19. The two roof plates 18 and 20 are provided with eleventh compartments 52 and 52a and twelfth compartments 53 and 53a separated by fold lines 50 and 50a.

Now, a process for making a carton pack of the type shown in FIGS. 2 to 5 with the blank of FIG. First, the blank 10 is folded along four longitudinal fold lines 11, 12, 13, 14, and the left three plates 17 corresponding to the three bonding plates 21, 26, 31 positioned on the right side thereof. , 22, 27) to the left end of appropriate bonding method such as adhesive or thermocompression bonding. This results in a square pillar with an open top and bottom. In this state, the front faces of the first compartments 34 and 34a and the third compartments 36 and 36a of the second and fourth lower plates 28 and 30 are in contact with the front faces of the second compartments 35 and 35a and the first compartment. The backs of the 34 and 34a and the third compartments 36 and 36a are folded and adhered to contact the backs of the first and third lower plates 27 and 29, respectively. Then, when the extended ends of the first and third lower plates 27 and 29 are joined to each other by a method such as thermocompression bonding or the use of a suitable adhesive, the bottom plate is formed so that the bottom of the square pillar is closed. In this state, the beverage can be filled inside through the open top. After the beverage is filled, the roof plates 18 and 20 and the gable plates 17 and 19 are folded along each fold line, and then joined by a method such as thermocompression or using an appropriate adhesive to be completely sealed.

1 and 2 to 5, two gable plates 17 and 19 are folded and sealed between two roof plates 18 and 20 which are inclined inwardly so that the ends are collected. At this time, the fourth compartments 43 and 43a of the gable plates 17 and 19 are folded inward to be almost horizontal, and the neighboring sixth compartments 45 and 45a and the seventh compartments 46 and 46a are rear sides thereof. Fold to touch. In addition, the junction part is as follows. The rear surfaces of the ninth compartments 48 and 48a and the tenth compartments 49 and 49a are the rear portions of the eleventh plates 52 and 52a of the adjacent roof plates 18 and 20 (of the roof plates partitioned by dotted lines in the drawing). On both sides). In addition, the sixth compartments 45 and 45a and the seventh compartments 46 and 46a are joined to each other on the back of the portion above the dotted line. The front faces of the ninth compartments 48 and 48a and the tenth compartments 49 and 49a are respectively joined to the front faces of the dotted lines of the sixth compartments 45 and 45a and the seventh compartments 46 and 46a, respectively. At this time, the fifth compartments 44 and 44a and the eighth compartments 47 and 47a are recessed inwards with some curved surfaces, respectively. The joining of the blanks is preferably done by thermocompression or adhesive. The carton pack 80 as shown in Figure 2 is made through the above process.

Now, the opening process of the carton pack will be described in detail with reference to FIGS. 2 to 5. First, the two wings (44, 18, 47, 20) on the side where the tenth fold lines 51, 51a of the two roof plates 18, 20 are provided in a completely sealed state as shown in FIG. And pull it outward. Then, as shown in FIG. 3, the two roof plates 18 and 20 are opened, and the joint surface of the portion on the dotted line between the ninth compartment 48 and the sixth compartment 45, the tenth compartment 49, and the seventh compartment. Bonding surface on the dotted line of the compartment 46, the back surface of the portion above the dotted line of the sixth compartment 45 and the bonding surface of the back surface of the portion above the dotted line of the seventh compartment 46, and the two eleventh compartments 52, 52a. Half of the bonding surface is attached to the back of each other. Then, there is an outlet 60 that can be plugged in or pour the contents once. To open the exit 60 completely, flip the two roof plates 18 and 20 completely back, as shown in FIG. 4, and then press the two edges between the roof plates 18 and 20 and the gable plates 17 and 19 forward. Push to Then, as illustrated in FIG. 5, the back surface of the ninth compartment 48 and the joining surface of the eleventh compartment 52 and the back surface of the tenth compartment 49 and the joining surface of the eleventh compartment 52a are separated. . At this time, it is easier to separate than the conventional carton pack, because the first, part of the exit is already open, and second, if the roof plate (18, 20) is pulled back completely (the state shown in Figure 4), the fourth , The fifth and eighth compartments 43, 44, and 47 are not flat and convexly forward, so that the two roof plates 18 and 20 are rolled back to push forwards to the ninth and tenth compartments. This is because it acts as a force for separating the back surfaces of the 48 and 49 and the joining surfaces of the eleventh sections 52 and 52a. The above described the carton pack opening process as an example. However, the adhesive part may be opened differently from the above example depending on the posture or operation of the user. For example, there may be a case where the portion formed by the protrusions (sixth compartment 45 and seventh compartment 46) falls only on one wing (44, 18) or (47, 20). In this case, since the outlet portion consisting of the sixth compartment 45 and the seventh compartment 46 protrudes, the outlet can be easily opened completely as shown in FIG. In addition, when the junction between the sixth compartment 45 and the seventh compartment 46 forming the central protrusion of the gable plate does not fall, the two wings (44, 18) and (47, 20) are easily pulled out. The junction can be broken. In some cases, the joining between the sixth compartment 45 and the seventh compartment 46 may not be performed. On the other hand, the outlet 60 may be opened by other methods in addition to the above method. In the fully sealed state as shown in FIG. 2, the body of the carton pack 80 is held by one hand and the tenth folding lines 51 and 51a of the two roof plates 18 are provided using two fingers of the other hand. Push both wings (44, 18) and (47, 20) outward from the inside. At this time, one side half of the roof plate (18, 20) serves as a lever, and the upper center portion of the roof plate (18, 20) serves as a support for the lever, so that the two roof plates (18, 20) are opened to the exit (60) ) Is formed. On the other hand, it is possible to adjust the adhesive force of each joint for smooth opening.

In the embodiment of FIG. 1, the two upper inclined fold lines (40, 41, 40a, 41a) and two horizontal fold lines 40, 4a meet from both lower ends of the gable plates 17 and 19 in the embodiment of FIG. A fold line leading to a point (ie, a fold line dividing the fifth compartments 44 and 44a and the eighth compartments 47 and 47a into triangles) may be added. In this case, when joined as shown in Fig. 2, the fifth compartments 44 and 44a and the eighth compartments 47 and 47a are slightly folded along the added fold line without forming a curved surface.
