Description

  The present invention relates to a paper container having a gable roof-type top that contains beverage liquids such as milk and juice.

  As a paper container for beverages typified by a milk carton, it is composed of a paperboard material with thermoplastic resin laminated on the front and back surfaces, and has four body panels connected via a body vertical folding line. A pair of gable roof forming panels opposed to each other at an upper end of the trunk panel and a pair of gable wall forming panels opposed to each other via a top horizontal folding line are formed by joining the edges to form a square cylindrical trunk. The pair of gable wall forming panels are folded between the pair of gable roof forming panels to form a top portion, and either the gable roof forming panel or the pair of gable roof forming panels is formed. A gable roof type paper container (gable top type) in which an opening is provided in one of the end wall forming panels is widely used.

  In such a paper container, when the contents are poured out, in general, the left and right barrels are gripped from the rear side of the opening side to tilt the paper container. When you hold it, the finger is not caught and it is extremely unstable to hold it with your finger, especially when the capacity of the paper container is large or when the surface of the paper container has water droplets. There was a problem that sometimes.

  To solve this problem, as shown in FIGS. 8 and 9, the trunk panel 52 connected to the gable roof forming panel 51 having the opening 50 is connected to the trunk section on both sides of the trunk panel 52. First inward curved lines 57 and 58 that are generally inwardly connected from the vicinity of the intersection of the folding lines 53 and 54 and the top horizontal folding line 55 to the vicinity of the intersection of the trunk vertical folding lines 53 and 54 and the bottom horizontal folding line 56 respectively. From the middle position in the longitudinal direction of the first auxiliary folding lines 57, 58 from the body panel 52 to the left and right body panels 59, 60 connected to both sides of the body panel 52, the body The second auxiliary folding lines 63 and 64 are provided so as to straddle the trunk vertical folding lines 53 and 54 on both sides of the part panel 52 and to the trunk vertical folding lines 61 and 62 on the other side of the left and right trunk panels 59 and 60, respectively. The second auxiliary folding line 63, 6 The trunk vertical fold lines 53 and 54 on both sides of the trunk panel 52 are crossed in a perpendicular state with one fold line, branch into two, extend in the lateral direction, and the first auxiliary folding lines 57 and 58 and the left and right trunk panels. A paper container connected to the body vertical folding lines 61 and 62 on the other side of 59 and 60 is disclosed (for example, see Patent Document 1).

  In the case of the paper container configured as described above, in use, the vicinity of the intersection between the body vertical fold lines 53 and 54 and the second auxiliary fold lines 63 and 64 on both sides of the body panel 52 in the body 65 is pressed. Recessed, the first auxiliary fold line 57, 58 is in a mountain fold state, and the second auxiliary fold line 63, 64 is in a valley fold state to form a recess in the middle in the height direction of the left and right body panel 59, 60, This concave portion is intended to be easily grasped with a finger hook.

WO 2009/141389 A2

  According to the paper container disclosed in Patent Document 1 above, in use, the vicinity of the intersection between the body vertical fold lines 53 and 54 and the second auxiliary fold lines 63 and 64 on both sides of the body panel 52 in the body 65 is pressed. Since the second auxiliary folding lines 63 and 64 straddle the trunk vertical folding lines 53 and 54 on both sides of the trunk panel 52 in an orthogonal state when a concave and concave force is applied, at the positions of the trunk vertical folding lines 53 and 54 The ridge angle portion a of the body portion 65 to be formed will be pressed against each other evenly across the intersection of the body portion vertical fold lines 53 and 54 and the second auxiliary fold lines 63 and 64, and the portion will be recessed. Requires a strong force, and if it is easily pressed with a strong force, the mountain corner portion a formed by the body vertical folding lines 53 and 54 in the portion is broken, and as a result, the first auxiliary folding lines 57 and 58 are mountain folded. It can not be expected that the second auxiliary folding line 63, 64 will break into the valley state. In particular, in the case of a paper container having a large capacity, this can be said further because the basis weight of the paperboard material is increased.

  Thus, in the above paper container, it is difficult to dent the vicinity of the intersection of the trunk vertical fold lines 53 and 54 and the second auxiliary fold lines 63 and 64 on both sides of the trunk panel 52 in the trunk section 65. It is troublesome to fold the panel 52 and the left and right body panels 59, 60 connected to both sides of the body panel 52 along the first auxiliary folding lines 57, 58 and the second auxiliary folding lines 63, 64. In other words, there was a problem that it would be cumbersome to use.

  An object of the present invention is to provide a paper container in which a body portion is deformed with a light force to form a concave portion, and the concave portion is easily gripped with a finger hook.

In order to achieve the above object, the invention described in claim 1 is made of a paperboard material in which a thermoplastic resin is laminated on the front and back surfaces, and includes four body panels connected via a body vertical folding line. The edge part is joined by the direction seal panel to form a square cylindrical trunk, and a pair of gable roof forming panels facing each other at the upper end of the trunk panel and a pair of gable wall forming panels facing each other at the top A pair of gable roof forming panels are connected to each other via a horizontal folding line, and the top of the pair of gable wall forming panels is formed between the pair of gable roof forming panels, and the gable roof forming panel is one of the pair of gable roof forming panels. Alternatively, in a gable roof type paper container in which an opening is provided in one of the pair of end wall forming panels, the gable roof forming panel or the end wall forming panel provided with the opening is connected. 1's The section panel, intersection or al of the barrel longitudinal fold line on both sides of the first body panel and said top horizontal fold line, inward from one another leading to a predetermined position toward the bottom transverse fold line side of the body portion longitudinal fold line First auxiliary folding lines each composed of a generally arc-shaped line are provided, and the first trunk panel extends from the one trunk panel to the left and right trunk panels connected to both sides of the first trunk panel. The trunk vertical fold line on the other side of the left and right trunk panels and the trunk vertical fold line on the other side of the left and right trunk panels across the trunk vertical fold line on both sides of the one trunk panel from the substantially middle position of each of the first auxiliary fold lines wherein the second auxiliary fold line formed at a downward generally arcuate one line leading to intersection with the top horizontal fold line, respectively.

  According to a second aspect of the present invention, the intersection of the trunk vertical fold line on both sides of the first trunk panel and the second auxiliary fold line according to the first aspect is from the upper end side in the vertical direction of the trunk. It is located in the range of 1/4 to 1/2 of the overall length of the body portion in the vertical direction.

  According to the paper container of claim 1, the other side of the left and right trunk panels extends from the substantially middle position of the first auxiliary folding line across the trunk vertical folding lines on both sides of the one trunk panel. The second auxiliary fold line connected to the body vertical fold line is substantially arc-shaped downward, so that the second auxiliary fold line straddles the body vertical fold line on both sides of the first body panel in an inclined state. In other words, when the vicinity of the intersection of the body vertical fold line and the second auxiliary fold line on both sides of the 1 body panel is pressed, the angle portion of the body formed at the position of the body vertical fold line is the second. When pressing in the dent direction across the intersection with the auxiliary folding line, the pressing action applied to the mountain corner will be shifted and the intersection with the second auxiliary folding line at the mountain corner will be easily deformed, and The second auxiliary fold line has a generally arcuate shape downward, and is formed at the position of the body vertical fold line. The force that acts on the first body panel and the left and right body panels along the deformation of the intersecting portion with the second auxiliary folding line at the angled corner portion causes the second auxiliary folding line to fold. The second auxiliary folding line that is generally downwardly arcuate is easily valley-folded, and at the same time, acts as a force for folding the first auxiliary folding line, and the first auxiliary folding line is also Since it is generally arc-shaped, it can be easily folded into a mountain, so that the body portion of the paper container can be easily deformed with a light force along the first auxiliary fold line and the second auxiliary fold line. .

  The body portion of the deformed paper container has a recess near the intersection of the body vertical fold line and the second auxiliary fold line on both sides of the body panel, and the body panel and the left and right sides are connected to the recess. As a result, the upper side of the second auxiliary folding line that has been valley-folded in the left and right trunk panels is directed outward, but the second auxiliary folding line has a generally arcuate shape downward. When the upper side surface of the second auxiliary fold line in the left and right body panel facing is gently bulged from the second auxiliary fold line and grasped from the rear side of the opening side so as to sandwich the recessed parts of the left and right body panels, Fingers are easy to hold on the upper side of the upper side of the second auxiliary folding line in the left and right body panel, especially when the capacity of the paper container is large or when the surface of the paper container has water drops, Can be used easily.

  Furthermore, in the case of a paper container having a low basis weight of the paperboard material, the rigidity becomes low and the body swells and becomes difficult to hold, but from the first auxiliary folding line provided on one body panel and the one body panel The second auxiliary folding line provided across the left and right trunk panels connected to both sides of the one trunk panel exhibits a rib effect to increase the rigidity of the paper container and suppress the swelling of the paper container. In addition, since the second auxiliary folding line can be easily valley-folded as described above, it is possible to easily form dents in the left and right body panels even in a swollen state, so that the paperboard material has a low basis weight. Even so, it can be easily grasped.

  According to the paper container of Claim 2, the intersection of the said trunk | drum vertical fold line and the said 2nd auxiliary fold line of the both sides of said 1 trunk | drum panel of Claim 1 is the vertical direction of a trunk | drum. Since it is located in the range of 1/4 to 1/2 of the overall length in the longitudinal direction from the upper end side, the vicinity of the intersection between the longitudinal fold line and the second auxiliary fold line on both sides of the 1 trunk panel is pressed. Since the depression near the intersection of the trunk vertical fold line and the second auxiliary fold line on both sides of the one trunk panel formed at the time is formed on the upper side from the vertical center of the trunk, When gripping from the rear side so as to sandwich the recessed portions of the left and right body panel, the lower side of the gripping position has a heavier weight distribution than the upper side, and can be gripped in a stable state.

Is folded, heated, sealed and sealed to form the bottom 39.

Of the trunk panels 4, 5, 6, and 7 constituting the trunk section 10, the trunk panel 5 connected to the gable roof forming panel 13 to which the opening 30 is attached via the top horizontal folding line 11 is connected to the trunk panel 5. both sides of the body portion longitudinal fold line 1,2 and intersection or these with the top horizontal fold line 11 parts panel 5, the body portion longitudinal fold line and second bottom lateral fold line 31 inwardly together lead to a predetermined position toward the side generally First auxiliary folding lines 40 and 41 each constituted by a single arc-shaped line are provided.

The body panel 5 and the left and right body panels 4 and 6 connected to both sides of the body panel 5 via the body vertical folding lines 1 and 2 are connected to the body panel 5 from the body panel 5 to the left and right body panels. 4, 6, across the trunk vertical folding lines 1, 2 on both sides of the trunk panel 5 from approximately the middle position of the respective first auxiliary folding lines 40, 41, in addition to the left and right trunk panels 4, 6. barrel longitudinal fold line second auxiliary fold line 42, 43 consists of a downward generally arcuate one line leading to intersection between 8,3 and the top transverse fold line 19, 20 of the side are provided.
In this example, the intersection C between the body vertical fold lines 1 and 2 and the second auxiliary fold lines 42 and 43 on both sides of the body panel 5 is 1 / of the overall length of the body part longitudinally from the upper end side in the longitudinal direction of the body part 10. It is located in the range of 4 to 1/2, preferably 1/4 to 1/3.

  According to the paper container of the first embodiment configured as described above, when the paper container is used, as shown in FIG. 2, the top horizontal fold line 11 is formed on the gable roof forming panel 13 to which the opening 30 is attached. And presses the vicinity of the intersection C between the body vertical fold lines 1 and 2 and the second auxiliary fold lines 42 and 43 on both sides of the body panel 5 connected to each other.

  By this pressing, the crest angle portion a of the body portion 10 formed at the position of the body portion vertical folding lines 1 and 2 is recessed along the intersection C between the body portion vertical folding lines 1 and 2 and the second auxiliary folding lines 42 and 43. At this time, the second auxiliary folding lines 42 and 43 extend from the substantially intermediate position of the first auxiliary folding lines 40 and 41 across the trunk vertical folding lines 1 and 2 on both sides of the trunk panel 5, The second auxiliary folding lines 42 and 43 are formed on the two sides of the body vertical folding lines 1 and 2 on the both sides of the body panel 5, respectively. 2 when the mountain corner a is pushed in the dent direction across the intersection C between the trunk vertical folding lines 1 and 2 and the second auxiliary folding lines 42 and 43, the mountain corner The pressing action applied to “a” is shifted and applied.

  Thereby, the intersection C part of the trunk | drum vertical folding lines 1 and 2 and the 2nd auxiliary folding lines 42 and 43 in the mountain corner part a of the trunk | drum 10 formed in the position of the trunk | drum vertical folding lines 1 and 2 deform | transforms easily. Also, since the second auxiliary folding lines 42 and 43 are generally arc-shaped downward, the trunk vertical folding lines 1 and 2 and the second folding lines 1 and 2 in the mountain corner portion a formed at the positions of the trunk vertical folding lines 1 and 2. The force that acts on the trunk panel 5 and the left and right trunk panels 4 and 6 to cause the second auxiliary folding lines 42 and 43 to fold in accordance with the deformation of the intersection C portion with the auxiliary folding lines 42 and 43 in the recess direction. The second auxiliary folding lines 42 and 43 that are substantially arc-shaped downward are easily valley-folded, and at the same time, act as a force that causes the first auxiliary folding lines 40 and 41 to be folded, 1 Since the auxiliary folding lines 40 and 41 are also generally arc-shaped, they are easily folded in a mountain, The trunk portion 10 of the container can be easily deformed with a small force along the first auxiliary fold lines 40, 41 and the second auxiliary fold line 42, 43 (see FIG. 4.).

  And the trunk | drum 10 of the deform | transformed paper container is dented in the intersection C vicinity of the trunk | drum vertical fold lines 1 and 2 and the 2nd auxiliary fold lines 42 and 43 of the both sides of the trunk | drum panel 5, and a trunk | drum panel continues to this dent. 5 and left and right body panels 4 and 6 are also recessed. As a result, the upper side of the second auxiliary folding lines 42 and 43 that are valley-folded in the left and right trunk panels 4 and 6 are directed outward, but the second auxiliary folding lines 42 and 43 are substantially arc-shaped downward, The upper side surfaces of the second auxiliary fold lines 42 and 43 in the left and right trunk panels 4 and 6 facing outward are gently bulged from the second auxiliary fold line, and as shown in FIG. When the left and right body panel 4, 6 is gripped so as to sandwich the recessed portions, the fingers are easily caught on the bulged upper side surfaces of the left and right body panel 6 above the second auxiliary folding lines 42, 43.

In particular, even in the case of a paper container having a basis weight of 150 to 350 g / m ² , the first auxiliary folding lines 40 and 41 provided on the body panel 5 and the body panel 5 to the body panel 5 The second auxiliary folding lines 42 and 43 provided across the left and right trunk panels 4 and 6 connected to the both sides of the knives exert a rib effect to increase the rigidity of the paper container and suppress the swelling of the paper container. In addition, since the second auxiliary folding lines 42 and 43 are easy to fold as described above, it is possible to easily form dents in the left and right trunk panels 4 and 6 even when the trunk is swollen. Even a paper container having a low basis weight of the material can be easily grasped. For example, in the case of a gable top type paper container having a basis weight of paperboard material of 250 to 330 g / m ² , the swelling of the trunk is slight, and even if there is swelling of the trunk, dents can be easily formed on the left and right trunk panels 4 and 6. Can be easily grasped.

  Further, in this example, the intersection C between the body vertical fold lines 1 and 2 and the second auxiliary fold lines 42 and 43 on both sides of the body panel 5 extends from the longitudinal upper end side of the body part 10 to the entire length of the body part longitudinal direction. Since it is located in the range of 1/4 to 1/2, it is formed when the vicinity of the intersection C between the trunk vertical folding lines 1 and 2 and the second auxiliary folding lines 42 and 43 on both sides of the trunk panel 5 is pressed. Since the dent in the vicinity of the intersection C between the body vertical fold lines 1 and 2 and the second auxiliary fold lines 42 and 43 on both sides of the body panel 5 is formed from the middle in the longitudinal direction of the body 10 to the upper side. When gripping from the rear side of the 30 side so as to sandwich the recessed portions of the left and right body panels 4 and 6, the lower side of the gripped position has a heavier weight distribution than the upper side and can be gripped in a stable state. it can. In particular, the intersection C between the trunk vertical fold lines 1 and 2 and the second auxiliary fold lines 42 and 43 on both sides of the trunk panel 5 is from 1/4 to the longitudinal length of the trunk section 10 from the longitudinal upper end side of the trunk section 10. When the position is in the range of 1/3, the lower side does not become too heavy and can be gripped in a more stable state.

  Moreover, in this example, since the stopper used as the opening part 30 is attached to the gable roof forming panel 13, between the trunk | drum vertical fold lines 1 and 2 and the 2nd auxiliary fold lines 42 and 43 of the both sides of the trunk | drum panel 5 When a depression is formed by pressing near the intersection C, the presence of the gable roof forming panel 13 effectively prevents the force that forms the depression from escaping in the direction of the opening 30, and the depression is easily formed. Can be formed.
