Description

  The present invention relates to a beverage paper container that can be perforated with a straw and drink its contents.

  Conventionally, in a beverage paper container filled with milk or the like, an opening piece is formed in a substantially circular or arc shape on the wall portion of the container so that the milk content can be drinked by piercing the straw into the wall portion of the container. It is formed by a half cut line. Moreover, a part of the half-cut line is cut off, and the cut-off part functions as a hinge (see, for example, Patent Documents 1 and 2).

  This opening piece may be provided on the back surface side of the wall portion of the container (for example, see Patent Document 1) or may be provided on the front surface side (for example, see Patent Document 2).

  Further, on the surface side of the wall portion of the container, a peeling piece is formed by half-cutting in a region where the opening piece is accommodated (see, for example, Patent Documents 1 and 2).

  In order to drink the beverage in the container, first, the peeling piece on the wall surface is peeled off, the opening piece is exposed or thinned, and then the tip of the straw is pressed against the opening piece. Thereby, an opening piece is fractured | ruptured in the location of a half cut, a straw penetrate | invades in a container, and can drink a drink of a content easily. Further, the broken opening piece enters the inside of the container with the hinge as a fulcrum and is held by the hinge so as not to fall into the beverage.

Japanese Patent No. 3549776 JP-A-10-45124

  However, since the opening piece of the conventional beverage paper container is formed so that a circular hole similar to the cross section of the straw is opened, when the straw is inserted into the container or when the contents are inserted and the contents are drunk, the straw unexpectedly There is a risk of falling inside. If the straw falls into the container, it becomes difficult to drink the contents.

  Moreover, since the half-cut line surrounding the circular hole of the opening piece is an arc-shaped continuous line except for the hinge portion, there is a problem that the opening piece is difficult to break when the tip of the straw is pressed.

  Therefore, an object of this invention is to provide the drink paper container which can eliminate the said problem.

  The present invention is for solving the above-described problems, and employs the following configuration.

  In addition, although the referential mark of drawing is attached | subjected with a parenthesis, this invention is not limited to this.
