BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a packaging body for packaging foods in the shape of an inverted cone such as ice cream, and uses a packaging material suitable for cutting the upper part to expose the contents .
The present invention relates to an easily openable package .

[0002]

2. Description of the Related Art Conventionally, an inverted conical wrapping material is used in which a packaging material made of a substantially fan-shaped blank is used as an inverted conical container to store contents such as ice cream and the upper edge of the blank is sealed and joined. Known from. In this type of package, for example, when the content is ice cream, the upper portion of the packaging material can be broken to allow the content to be eaten while exposing it in stages.

[0003] By the way, conventionally, in the above-mentioned inverted-conical package, a flap for starting tearing is simply provided on one side edge of a blank as a packaging material, and the upper part of the container is torn off by pulling this flap. It is normal to Further, in Japanese Utility Model Publication No. 2-26806, a blank used as a packaging material for an inverted conical package is formed from a sheet such as a uniaxially stretched polyethylene film, and the central axis in the longitudinal direction of the blank is relative to the stretching axis of the sheet. It has been proposed that the blank is formed by cutting or punching so as to be inclined at a predetermined angle, and a flap for initiating a tear is extended above one side edge of the blank. With such a configuration, the packaging material can be cut down in a spiral shape with substantially the same width as the flap by pulling the flap with respect to the body portion.

[0004]

DISCLOSURE OF THE INVENTION As a means for facilitating the tearing of the wrapping material of an inverted conical packaging body, it is necessary to simply provide a flap for initiating tearing on one side edge of the blank as described above. Only the part close to can be torn off, so it is not always possible to open it securely and neatly. Further, when using a blank cut or punched out from a sheet such as a uniaxially stretched polyethylene film as described in the above publication so as to be inclined at a predetermined angle with respect to the stretching axis of the sheet, it is merely said that a flap is provided. The tearing direction is more stable and the cut edge is cleaner than that of the one, but in the case of such a uniaxially stretched sheet, if the tearing part is cut in the middle, there will be no new tear opening and it will be rather difficult to open. Becomes In addition, uniaxially stretched polyethylene film and the like are expensive. Furthermore, in the case of an inverted cone-shaped package that seals the upper edge portion, it is inconvenient if the tearing direction is from top to bottom to tear and expose the contents.

Further, it is conceivable to use perforations, which is a conventional means for facilitating tearing, but when filling ice cream etc., there is a problem such as leakage, so that perforations are simply added. I can't go.

The present invention has been made in view of the above problems, and the upper part of the packaging material of an inverted conical packaging body can be easily and surely torn by hand and removed, and the cost is increased. Easy to prevent leakage of contents
The purpose is to obtain an openable package .

[0007]

Polyethylene film that closes perforations on the back of the rank
Are laminated.

In addition, the perforation is set to one, and one of the perforations is
The creases start from the bottom of the tear start flap and
Along the side of the inverted conical shape
It is also possible to provide up to a position where it does not exceed .
Further, in that case, it is preferable that the side edge joining portion has a weakly adhesive structure at a portion above the lower portion of the tear initiation flap.

[0009]

The packaging material made of a substantially fan-shaped blank is wound in an inverted conical shape, and the opposite side edges are overlapped and joined together. After the contents are stored, the upper edge portion is heat-sealed. It is sealed by. In the inverted conical packaging body thus formed, the packaging material can be torn along the perforations by pinching and pulling the tear initiation flap, and the torn portion can be removed to remove the upper portion of the contents. Can be exposed.

[0010] Then, to form a band-like tear portion on the extension of the tear-initiation flap, along the top and bottom of the tear-initiation flap reversed conical side surface of the package as a starting point
In the case where two parallel perforations are provided diagonally upward, by grasping and pulling the tear start flap, the strip-shaped tear portion and the packaging material portion on the extension of the tear tear flap are directed diagonally upward. Torn.

Further, in the case where one perforation is provided with the lower portion of the tear start flap as a starting point, the tear start flap is pinched and pulled to form the perforation. At the same time that the packaging material is torn along the side, the side edge joint portion above the tear initiation flap is peeled off, and the upper portion of the packaging body is greatly opened. At that time, in the case where the side edge joint portion has a weak adhesive structure in a portion above the lower portion of the tear initiation flap , the unsealing property is particularly good.

Further, since the polyethylene film is laminated on the back surface of the blank and the perforations are closed on the side in contact with the contents, the liquid contents are prevented from leaking.

Further, if the perforation exceeds the height of the contents, the perforation may be broken by an external force at the bent portion of the upper edge portion which is overlapped and sealed, but in the present invention, Since the perforations are located at a position that does not exceed the height of the contents, such perforations can be prevented from being damaged by external force during manufacturing or distribution.
