JP 2001-171643 A

In the conical package described above, the consumer removes the packaging portion above the first breaking line 18 and eats from the exposed upper portion of the ice cream. Thereafter, in order to eat the ice cream in the lower portion, it is necessary to remove the packaging portion below the first breaking line 18. At that time, generally, the edge 19 of the thermal bonding region extending along the ridgeline of the cone is picked, and the packaging portion remaining below is peeled off.
However, there is a problem that the edge 19 is difficult to pick and the packaging part remaining on the lower side is difficult to remove, particularly when the thermal bonding is firmly performed.

  In view of the above-described conventional problems, an object of the present invention is to provide a conical package that can easily remove a packaging portion remaining on the lower side.

The present invention was conceived in order to effectively solve the above problems, and provides a conical package having the following features.
The conical package of the present invention includes an opening knob provided on a conical peripheral wall, and a first fracture on the apex side of the cone extending in the circumferential direction on the peripheral wall surface with the knob interposed therebetween. A conical package comprising a tangent line and a second rupture line on the large diameter side, and configured to tear and open a peripheral wall portion between the first rupture line and the second rupture line.
And the 1st breaking cut line is formed so that the edge shape of the package part which remains may be the mountain shape which protrudes upwards rather than other parts in the state which opened the above-mentioned peripheral wall part. Has been.
Furthermore, a third breaking line extending in the circumferential direction on the peripheral wall surface is provided on the cone apex side of the first breaking line, and extending from a position in the vicinity of the skirt of the chevron-shaped portion to the third breaking line. A guide breaking line is provided.

In the conical packaging body of the present invention having the above-described configuration, the edge shape of the remaining packaging body part in the state where the peripheral wall part between the first breaking line and the second breaking line is torn and opened, It becomes the mountain shape which protrudes upwards. Therefore, it is possible to easily break the remaining package part by picking this part.
A third break line extending in the circumferential direction on the peripheral wall surface is provided on the apex side of the first break line, extending from the position near the skirt of the chevron-shaped portion to the third break line. There is a guide break line that exists.
That is, when the consumer picks up the chevron-shaped portion and starts the breaking operation, the breakage passes from the base of the chevron-shaped portion through the guide breakage cut line and proceeds on the third breakage cut line. In this way, the remaining portion of the conical package can be removed easily and reliably.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 2 is a perspective view of a conical package 50 according to an embodiment of the present invention. FIG. 2A shows a state in which the conical packaging body is first opened, and FIG. 2B shows a state in which a chevron-shaped portion 61a described later appears.
This conical package is formed by winding the substantially fan-shaped packaging material (blank) 50 shown in FIG. 3 in a conical shape to adhere both side edges, and three adhesives formed radially at substantially equal intervals. The portion 58 is configured by sealing the large diameter side.

On the conical peripheral wall of the package 50, a knob 55 for opening is formed, and two breaking lines are provided so as to sandwich the knob 55. That is, the first breaking line 61 on the side close to the conical vertex 56 and the second breaking line 62 on the large diameter side located on the upper side in FIG.
The first breaking line 61 is generally formed in an arc shape centered on the conical vertex 56, but has a chevron-shaped portion 61a in a part thereof.
On the other hand, the second breaking line 62 is formed in a substantially spiral shape so as to gradually move away from the first breaking line 61 as it moves away from the knob 55.
The conical package 50 can be opened by picking the knob 55 and tearing the peripheral wall portion 60 between the first break line 61 and the second break line 62 in the direction of arrow A.

≪Yamagata shaped part 61a≫
FIG.2 (b) has shown the state which picked the knob | pick part 55 and torn off the surrounding wall part 60 (the upper part of an eating ice cream is shown with the broken line). As can be seen from this drawing and the blank development view of FIG. 3, the first breaking cut line 61 shows that the edge shape of the remaining package body part is at least partly other part in the state where the peripheral wall part 60 is broken and opened. It forms so that it may become the mountain shape 61a which protrudes rather than.
That is, when the peripheral wall portion 60 is torn, a chevron-shaped portion 61a that protrudes upward and functions like a tab appears, so that it is possible to easily break the remaining package portion by picking this portion.

  The specific shape of the chevron-shaped portion 61a is not limited to that shown in the figure, and any shape that protrudes upward and is suitable for a consumer to pick it with a finger is sufficient. For example, it may be a mountain-shaped portion of a shape such as a building that is composed only of straight lines.

≪Third break line 63 and guide break line 65≫
A third breaking line 63 extending in the circumferential direction on the peripheral wall surface is provided on the cone apex 56 side of the first breaking line 61 (that is, the side opposite to the second breaking line 62). And the guide fracture | rupture cutting line 65 extended to the 3rd fracture | rupture cutting line 63 is formed from the skirt vicinity position 61b of the mountain-shaped part 61a.
That is, when the consumer picks up the chevron-shaped portion 61a and starts the breaking operation in the direction of arrow B (FIG. 2 (b)), the breakage passes from the skirt 61b of the chevron-shaped portion through the guide breaking line 65, and the third breakage occurs. Proceed on the cut line 63. In this way, the remaining part of the conical package can be removed easily and reliably.

<< Easy breakage area 64 >>
In FIG. 2 (b), when the mountain-shaped portion 61 b is picked and broken in the direction of the arrow B, the break that proceeds on the third break line 63 makes one round on the conical peripheral wall and enters the bonded edge region 70. To reach.
The bonded edge region 70 is a region in which the substantially fan-shaped blank 50 shown in FIG. In this region, the third break line 63 connects the first end 63a and the second end 63b. That is, the third breaking line 63 extends from the first end 63 a near the one end edge of the substantially sector blank 50 to the second end 63 b near the other end edge, and is connected in an annular shape in the bonding edge region 70. .
Here, in order to absorb the winding error in the manufacturing process, an easily breakable region 64 is provided. That is, the second end of the third break line 63 is branched into a plurality of portions to form an easily breakable region 64 having a certain spread.
If such an easily breakable region 64 is not provided, if the both ends 63a and 63b of the third break line 63 are not exactly matched in the winding process of the blank 50, the break that proceeds on the third break line 63 will occur. The bonded edge region 70 cannot be overcome smoothly.
By providing the easily breakable region 64 having a certain area spread, the deviation in the winding process is absorbed, and the breakage proceeds smoothly over the bonded edge region 70.

Contrary to the illustrated example, an easily breakable region 64 may be provided at the first end 63 a of the third breakage cut line 63.
That is, when the blank 50 is wound with the easily breakable region 64 provided on one of the first end 63a and the second end 63b, the other of the first end 63a and the second end 63b is connected to the easily breakable region 64. By configuring as described above, winding error can be absorbed.

≪Blank laminated structure and broken cut line structure≫
The laminated structure of the blank (packaging material) 50 for producing the conical package is “plastic film / aluminum foil / paper / thermoadhesive resin layer” from the outer surface side. As the plastic film, biaxially stretched polyethylene terephthalate or biaxially stretched polypropylene can be used.
The first break line 61, the second break line 62, the third break line 63, and the guide break line 65 pass through the plastic film, the aluminum foil, and the paper, and are cut to the middle of the thermal adhesive resin layer. Is formed. That is, each cutting line does not penetrate the entire packaging material 50 but is in a half-cut state. By setting it as a half-cut state, the food inside can be blocked from the outside, which is preferable in terms of hygiene and can reduce the risk of inadvertent breakage.
Since the heat-adhesive resin layer has a relatively small tear strength, if the plastic film, the aluminum foil, and the paper are allowed to penetrate, the heat-adhesive resin layer can be easily torn along each cut line.

  However, as for the laminated structure of the blank and the structure of the breaking line, any form other than the above can be adopted.

The perspective view explaining the conventional conical packaging body. The perspective view of the conical packaging body which concerns on one Embodiment of this invention. The expanded view of the blank which comprises the conical packaging body of FIG.
