Description

The present disclosure relates to gable-top containers.

Conventionally, gable-top containers made of paperboard material with thermoplastic resin laminated on the front and back surfaces have been widely used as paper containers for beverages, etc., and various forms have been proposed (for example, Patent Document 1). .

Generally, gable-top containers of single-drink size (for example, 500 ml or less) are often accompanied by a straw, and the amount of straw consumed is enormous. Drinking straws are typically plastic straws, and straws that are discarded after use are difficult to decompose in the natural environment and are therefore not environmentally friendly. In particular, the amount of milk provided in school lunches is enormous, and the amount of straws discarded is also enormous. Although it is possible to drink by attaching the spout directly to the spout of a conventional gable-top container, the pointed, beak-shaped spout makes it extremely difficult to drink.

As mentioned above, the applicant of the present application proposes a gable top type container in which the first roof panel, the second roof panel, the first gable wall panel, and the second gable wall panel are each provided with a vertical fold line. We proposed a gable-top container that does not require a straw and has an easy-to-drink mouth shape. Since it is preferable that such a gable-top type container allows everyone to enjoy the above-mentioned advantages, it is preferable that the entire surface can be opened easily by peeling off all the joints of the above-mentioned top seal portion.
The inventors of the present application conducted random studies and found that the entire surface can be easily opened by using a predetermined material that has been conventionally used.

That is, the gable-top container of the present embodiment includes a cylindrical body in which four side panels, a first side panel, a second side panel, a third side panel, and a fourth side panel are connected in this order; a bottom portion connected to the lower end of the body and having a square shape; and a gable roof portion connected to the upper end of the body, the gable roof portion being connected to the first side panels facing each other. a first roof panel connected to the third side panel; and a second roof panel that faces each other in a direction intersecting the opposing direction of the first roof panel and the second roof panel, and A first gable wall panel connected to the second side panel and a second gable wall panel connected to the fourth side panel, which are folded in between the second roof panel and the upper end of the first roof panel. A gable with a capacity of 500 ml or less, comprising an upper end of the second roof panel, and a top seal portion formed by joining the upper end of the first gable panel and the upper end of the second gable panel. The cable top type container is a top type container, and the cable top type container is composed of only a laminate in which a sealant layer, a paper base material, and a sealant layer are laminated in this order, and a printed layer, and the printed layer is composed of a laminate in which a sealant layer, a paper base material, and a sealant layer are stacked in this order, and a printed layer. the first roof panel and the second roof panel are respectively disposed on the opposite side of the layer from the paper substrate or between the sealant layer and the paper substrate, and each of the first roof panel and the second roof panel has a vertical bending line extending from the center of the lower end of the outer adhesive piece that is the upper end of the panel to the center of the lower end of the first roof panel and the second roof panel; Each of the second gable panels has a vertical fold line extending from the center of the top end to the center of the bottom end.

The gable top type container of the present embodiment further includes the four vertical bending lines arranged on the first roof panel, the second roof panel, the first gable panel, and the second gable panel, respectively. When all the joints of the top seal part are removed and the entire surface is opened, each of the four vertical bending lines is made into a mountain fold, so that the shape of the opening transforms into an octagonal cup-shaped container. It is preferable that it function as such.

Hereinafter, the gable top type container of this embodiment will be explained in detail.
FIG. 1(a) is a perspective view illustrating the gable top type container of this embodiment. FIGS. 1(b) and 1(c) are a perspective view and a top view, respectively, of the gable top type container of FIG. 1(a) after opening. FIG. 2 is a developed view of the gable top type container of this embodiment. The gable-top container 1A of the present embodiment shown in FIGS. 1 and 2 is a gable-top container with a capacity of 500 ml or less, and includes a first side panel S1, a second side panel S2, a third side panel S3, and a fourth side panel. A cylindrical body 2 to which four side panels of panel S4 are connected, a bottom 3 connected to the lower end of the body 2 and having a square shape, and a gable roof 4 connected to the upper end of the body. have The gable roof section 4 includes a first roof panel R1 connected to the first side panel S1 and a second roof panel R2 connected to the third side panel S3, which face each other, and the first roof panel R1 and the second roof panel R2. A first gable wall panel W1 and a fourth side panel that are connected to the second side panel S2, facing each other in a direction crossing the opposite direction, and folded between the first roof panel R1 and the second roof panel R2. The second gable wall panel W2 connected to S4 is formed by joining the upper end portions of the first roof panel R1 and the second roof panel R2, and the upper end portions of the first gable wall panel W1 and the second gable wall panel W2. A top seal portion T is provided.

In this example, the first roof panel R1 and the second roof panel R2 are connected from the lower end center Ca of the outer adhesive piece 12, which is the upper end part constituting the top seal part T, to the first roof panel and the second roof panel, respectively. Although the vertical bending lines X1 and X3 extending to the center C2 of the lower end of the panel are provided, and the outer adhesive piece 12 does not have a vertical bending line, the present disclosure is not particularly limited to this. A vertical bending line extending from the vertical bending lines X1 and X3 may be formed on the outer sticking portion 12.
Moreover, the first gable wall panel W1 and the second gable wall panel W2 each have vertical bending lines X2 and X4 extending from the upper end center C3 to the lower end center C4.

FIG. 8(a) shows a perspective view of a conventional gable top type container. After opening the gable top type container 100 as shown in FIG. 8(a), the spout becomes beak-shaped. Although it is possible to drink by directly attaching the mouth to such a spout, the pointed shape of the spout makes it extremely difficult to drink. It is also possible to peel off all the joints of the top seal portion T' to open the entire surface and drink directly into the mouth, but the opening will have a substantially rectangular shape as shown in FIG. 8(b). Moreover, since the roof panels R11 and R12 are valley-folded once when opened, they tend to dent inward, and the shape of the opening is not maintained and becomes unstable. Therefore, there is a problem that it is difficult to drink and spills when drinking.

On the other hand, in the case of the gable-top type container of the present embodiment, each of the first roof panel R1 and the second roof panel R2 is connected to Each of the first gable wall panel W1 and the second gable wall panel W2 has vertical bending lines X1 and X3 extending from the center of the lower end of the first roof panel and the second roof panel, and each of the first gable wall panel W1 and the second gable wall panel W2 has a vertical bending line extending from the center of the upper end to the center of the lower end. By having the bending lines X2 and For example, it can be made into an octagonal shape, and the shape of the opening can be maintained (FIGS. 1(b) and 1(c)). Therefore, it can be transformed into a cup-like container, and has a drinking spout shape that makes it easy to drink by directly touching it.

Since the gable-top container of this embodiment does not require a straw, it can contribute to eliminating plastics and reducing marine debris. In addition, since no straw is included, it is easy to pack into cardboard boxes, etc., and space can be saved when displaying products at stores. Furthermore, after drinking, the container can be easily unfolded into a flat shape, making it easy to recycle, and even when not unfolded into a flat shape, there are more folding lines than conventional gable-top containers, making it easy to fold. It is easy to make and can be thrown away thinly, which also leads to a reduction in waste volume. Furthermore, it can be manufactured using a conventional filling machine, which is advantageous in terms of cost.

Also, compared to drinking by attaching the spout of a conventional gable-top type container, the remaining amount can be seen, making it easier to adjust the tilt when drinking. Therefore, it is possible to prevent the drink from spilling out of the mouth, and it is possible to drink the drink to the end. This can prevent the contents from scattering when unfolding into a flat shape or crushing and folding.

I. Configuration (1) Gable roof section (a) Roof panel and gable wall panel The gable roof section includes a first roof panel R1 and a second roof panel R2, and a first roof panel R1 and a second roof panel R2, which face each other. It has a first gable wall panel W1 and a second gable wall panel W2 that face each other in a direction intersecting the opposing direction of and are folded between the first roof panel R1 and the second roof panel R2. The first roof panel R1 and the second roof panel R2 are connected to the first side panel S1 and the third side panel S3, respectively, via a horizontal bending line y. The first gable wall panel W1 and the second gable wall panel W2 are connected to the second side panel S2 and the fourth side panel S4, respectively, via the horizontal bending line y. The first roof panel R1, the first gable wall panel W1, the second roof panel R2, and the second gable wall panel W2 are arranged in an annular manner in this order.

A pair of opposing roof panels (a first roof panel R1 and a second roof panel R2) are located outside the square-shaped inclined piece 11 and the inner adhesive piece 15 at the top seal portion T of the gable-top container 1, respectively. It is formed by an outer adhesive piece 12 located at. In addition, in the top seal portion T, the surface of the outer adhesive piece 12 on the inside of the container serves as a bonding surface, and the surface of the inner adhesive piece 15 serves as a surface on the outer side of the container and the surface on the inner side of the container.

A pair of opposing end wall panels (first end wall panel W1 and second end wall panel W2) each have a folding piece 13 connected to the side panels S2 and S4, and a folding piece 13 connected to the folding piece 13. It is formed of a pair of folded back pieces 14 which are connected to each other and are connected to the inclined piece 11, and a pair of inner adhesive pieces 15 which are connected to the pair of folded back pieces 14.

(b) Top seal portion The gable roof portion in the present disclosure is formed by joining the upper end portions of the first roof panel R1 and the second roof panel R2, and the upper end portions of the first gable wall panel W1 and the second gable wall panel W2. It has a top seal part T.

Specifically, each outer adhesive piece 12 at the upper end of the first roof panel R1 and the second roof panel R2 is attached to each inner adhesive piece 12 at the upper end of the first gable wall panel W1 and the second gable wall panel W2. It is formed wider than each inner adhesive piece so as to protrude from the adhesive piece 15. The top seal part is formed by folding the folding line between the folding piece 13 and the folding piece 14 inward, using each boundary as a folding line, and then forming the top seal between the opposing gable wall panels (the first gable wall panel W1 and the second gable wall panel W1). W2) is folded between the roof panels (first roof panel R1 and second roof panel R2), and the opposing inclined pieces 11 are folded inward, and each inner adhesive piece 15 is overlapped by each outer adhesive piece 12. It is formed by aligning them together and gluing the overlapping portions together.

(c) Vertical bending line In the present disclosure, each of the first roof panel R1 and the second roof panel R2 extends from the lower end center Ca of the outer adhesive piece 12, which is the upper end portion constituting the top seal portion T, to the first roof panel R1 and the second roof panel R2. Each of the first gable wall panel W1 and the second gable wall panel W2 has vertical bending lines X1 and X3 extending to the lower end center C2 of the panel R1 and the second roof panel R2, and the first gable wall panel W1 and the second gable wall panel W2 are The second gable wall panel W2 has vertical bending lines X2 and X4 extending from the upper end center C3 to the lower end center C4. By providing four vertical bending lines in this way, by peeling off all the joints of the top seal part to open the entire surface, and then mountain-folding these vertical bending lines, the opening shape can be made circular rather than square. It can be a close polygon, for example an octagon, and still retain its opening shape. Such vertical bending lines are all formed as mountain folds.

The vertical bending lines X1, X3, X2 and X4 of the first roof panel R1, the second roof panel R2, the first gable wall panel W1 and the second gable wall panel W2 extend beyond the horizontal bending line y, respectively. It is preferable that the first side panel S1, the third side panel S3, the second side panel S2, and the fourth side panel S4 are also formed.

The length of the vertical folding line beyond the horizontal folding line y (the length of the vertical folding line on the side panel) must be 1/5 or more of the length of the body 2 (i.e., the longitudinal length of the side panel). is preferable, and it is more preferable that the length is 1/4 or more of the length of the body portion 2. This is because the shape of the opening can be easily maintained in an octagonal shape after opening. On the other hand, it is preferably 3/5 or less of the length of the body 2, and more preferably 1/2 or less of the length of the body 2. This is because it is possible to improve the stability of the shape of the body when drinking by holding the body in the hand.

Here, the four vertical bending lines may not be formed at the intersections with the horizontal bending lines that intersect with each other.
FIG. 4 is a perspective view illustrating a gable-top container having such a vertical fold line. FIG. 5 is a developed view thereof.

In this example, the first roof panel R1 and the second roof panel R2 are each arranged in a predetermined direction upwardly from the horizontal bending line y from the lower end center Ca of the outer adhesive piece 12, which is the upper end portion constituting the top seal portion T. Vertical bending lines X1 and X3 are formed between the position P1 _and the position _P1 , which is a distance l1 away. Further, the first gable wall panel W1 and the second gable wall panel W2 each have _a vertical bending line _X2 , X4 is formed.

Note that the vertical bending lines X1 and X3 do not necessarily need to be in contact with the lower end center Ca, and may be arranged at a distance comparable to a predetermined distance _l1 described later, for example. .

The gable top type container of this example is preferable in terms of appearance because the vertical bending line does not intersect with the horizontal bending line.

Incidentally, even if there is no vertical bending line at the part that intersects with the horizontal bending line y, as long as the rectangular inclined piece 11 of the first roof panel R1 and the second roof panel R2 has a vertical bending line, the top When all the joints of the seal portion are peeled off to open the entire surface, the horizontal bending line y can also be easily bent.

Specifically, the predetermined distance _l1 and the predetermined distance _l2 are, for example, 0.5 mm or more, may be 1 mm or more, may be 2 mm or more, and may be 5 mm or more. Good too. On the other hand, for example, it is 15 mm or less, and may be 10 mm or less. The predetermined distance l ₁ and the predetermined distance l ₂ may be the same or different.

In this example, the vertical folding lines X1, X3, X2, and X4 of the first roof panel R1, the second roof panel R2, the first gable panel W1, and the second gable panel W2 are the horizontal folding line y, respectively. It is preferable that they are also formed on the first side panel S1, third side panel S3, second side panel S2, and fourth side panel S4 so as not to overlap.

Specifically, the vertical bending line is formed on each of the first side panel S1 and the third side panel S3 so as to extend downward from a position P3 that is a predetermined distance _l3 away from the horizontal bending line y. and is formed on each of the second side panel S2 and the fourth side panel S4 so as to extend downward from a position a predetermined distance _l4 away from the horizontal bending line y. preferable.

Specifically, the predetermined distance _l3 and the predetermined distance _l4 are, for example, 0.5 mm or more, may be 1 mm or more, may be 2 mm or more, and may be 5 mm or more. Good too. On the other hand, for example, it is 15 mm or less, and may be 10 mm or less. The predetermined distance _l3 and the predetermined distance _l4 may be the same or different.

(d) Display section As shown in FIG. 3, the gable top type container of the present disclosure is provided with a spout display section Q1 indicating that it is a drinking spout on the first end wall panel W1 and the second end wall panel W2. It is preferable. The first roof panel and the second roof panel come in contact with people's hands during transportation, but the first gable wall panel and the second gable wall panel do not come into contact with people's hands. It is hygienic and preferable to use the upper end of the second gable wall panel as the drinking spout. In addition, since the inner adhesive pieces 15 of the first gable wall panel W1 and the second gable wall panel W2 have the outer surface of the container as the bonding surface (the front and back bonding parts in the exploded view of FIG. 3), after opening the package, The surface (outside surface of the container) may peel off. Therefore, the spout display part Q1 is printed on either or both of the fold-in piece 13 and the fold-back piece 14 below the inner adhesive piece 15 in the first end wall panel W1 and the second end wall panel W2. is preferred. In addition, in the developed view in FIG. 3, the portions that will be bonded when forming the gable top type container are shown with diagonal lines.

(e) Others The first roof panel R1 and the second roof panel R2 in this embodiment are usually not provided with a plastic pouring tool. Conventionally, for paper containers with a relatively large capacity, a circular opening is formed in the paper container itself, and a plastic pouring device with a flow path for dispensing the contents is attached to this opening. However, since the gable-top type container in this embodiment is of a single-drink size, such a plastic pouring device is not provided.

(2) Body The cylindrical body 2 includes four side panels S1, S2, S3, and S4 that extend in the circumferential direction (horizontal direction) of the cylindrical body 2, and usually also includes a seal panel S5. . As shown in the developed view shown in FIG. 2, for example, the side panels S1, S2, S3, and S4 are formed into a substantially rectangular cylindrical shape by heat-sealing the seal panel S5 connected to the side panel S4 to the side panel S1. A body portion 2 is formed. The side panels are connected to each other via body vertical fold lines a that extend in the vertical direction. In the developed view shown in FIG. 2, side panel S1 - side panel S2 - side panel S3 - side panel S4 - seal panel S5 are arranged in this order, but for example, side panel S2 - side panel S3 - side panel They may be arranged in the order of S4-side panel S1-seal panel S5. In this case, the seal panel S5 is heat-sealed to the side panel S2, thereby forming the substantially rectangular cylindrical body portion 2.

As described above, it is preferable that each of the four side panels S1, S2, S3, and S4 is provided with vertical bending lines X1 to X4.

Preferably, the first side panel or the third side panel is provided with a handle. Attaching a handle makes it easier to hold, carry to your mouth, and drink. Furthermore, it is easier to maintain the shape of the torso compared to drinking by supporting the torso with your hand. Preferably, the handle is foldable and retractable. It is possible to suppress an increase in the space required for the handle during storage, transportation, etc. Examples of the foldable handle include the handle Z1 shown in FIGS. 6(a) to 6(c). As shown in the exploded view of FIG. 6(a), the foldable handle Z1 is attached to the first side panel or the third side panel from the adhesive part Z11 and the adhesive part Z11 in the horizontal direction along the side panel. It has an extended handle part Z12. When in use, the handle Z12 is used in an upright position, as shown in FIGS. 6(b) and 6(c). FIG. 6(c) is a plan view of the gable top type container 1 of FIG. 6(b) viewed from the side panel S2 side.

Preferably, the first side panel or the third side panel is provided with a fall prevention band into which a hand (eg, palm or fingers) can be inserted between the side panel and the first side panel. By providing a fall prevention band, the container can be gripped reliably. Preferably, the fall prevention band is foldable and retractable. The foldable fall prevention band Z2 shown in FIGS. 7(a) to 7(c) is a band-shaped handle into which a hand can be inserted, and is provided vertically on the first side panel or the third side panel. Such a fall prevention band Z2 has a valley fold line Z21 at a predetermined position downward from the upper end, and further has a mountain fold line Z22 below, and in the mountain folded state, the upper and lower ends are connected to a gable top. It is installed by being joined to the first side panel or the third side panel of the mold container (FIG. 7(a)). When in use, as shown in FIGS. 7(b) and 7(c), by pulling it out, there is enough slack to easily insert a hand. FIG. 7(c) is a plan view of the gable-top container 1 of FIG. 7(b) viewed from the side panel S2 side.

It is provided with a seal panel B5 which is connected to the lower end of the seal panel S5 and connected to each other via the broken line b. A pair of valley fold lines d are formed on the bottom panels B2 and B4.

II. Opening shape after opening The opening method of the gable top type container of the present disclosure is to open both roof panels (R1, R2) (overlapping portion of the inclined piece and the folded piece) of the gable roof part of the container to the first gable wall panel W1. Insert your thumb into the cavity formed by the folding or folding of the top seal part T, grasp it with your thumb and forefinger, and peel off the overlapping parts of both slanted pieces and folded pieces from the top seal part T by pushing outward. Push it out. This time, if you apply a crushing force to the overlapping edges of both of the peeled slanted pieces and the folded piece between your thumb and remaining fingers, the inner adhesive piece 15 will peel off from the outer adhesive piece 12. The folded pieces and folded pieces of the gable wall panel are bent back and opened. Next, by opening the opposite side in the same way, all the joints of the top seal portion are peeled off, and the entire surface is opened. At this time, grasp the corner between the first roof panel and the first gable panel and the corner between the second roof panel and the second gable panel, pull it diagonally outward, and then By grasping the corner between the first roof panel and the second gable wall panel and the corner between the second roof panel and the first gable wall panel and pulling it diagonally outward, the entire surface can be easily opened. Note that the order of pulling may be reversed. Thereafter, by mountain-folding each roof panel and each gable wall panel along four vertical folding lines, the opening becomes a polygon that is closer to a circle than a quadrangle, for example, an octagon.
