Description

The present invention makes it possible to create a spout that can be created more easily than the conventional product. A gabled roof-type paper container that can be selected or created on the gable wall forming panel by selecting a straw insertion hole suitable for the thickness and shape of the straw to be used from several options Is.
In addition, a paper container of a type other than the gable roof type, such as a brick type, a cylindrical type, or a tetra type, which has been a mechanism for creating a spout or a straw insertion hole using a conventional basket, can be easily and manually used. Paper containers that can be created, and paper containers that can easily create spouts and hose insertion holes by storing liquids and particulate substances other than beverages. Also includes general ones.

  Conventionally, in order to open a gable roof type paper container and create a spout, the upper part of the paper container is folded so that the gable roof forming panel is folded and the attic forming panel and the gable wall forming panel are exposed. It was necessary to create the spout by opening the joint part of the top seal panel to the left and right, peeling off the joint part of the inner top seal panel and the outer top seal panel that appears by this with nails, etc. If you do not peel it off well, the packaging material will be broken and the spout will be deformed, and when you pour the contents of the liquid beverage into the cup, it may spill out of the cup. There is known a method in which a plastic spout is provided on a panel at the manufacturing stage. (See Patent Document 1)

  Another solution is to attach a tongue (handle) to the inner top seal panel with a finger to make it easier to peel off the joint between the inner top seal panel and the outer top seal panel. A device is also known that allows the joint between the inner top seal panel and the outer top seal panel to be easily peeled off by gripping and pulling. (See Patent Document 2)

  In addition, the shape of the spout formed by the conventional gable roof type paper container is constant, it has a long rhombus shape in the lateral direction, the opening area is small, and the liquid flows out in a state of lateral expansion. Since it has the drawback of being difficult, as a solution to this problem, a device for changing the shape of the spout into a more vertically long shape is also known. (See Patent Document 3)

In addition, a conventional method of drinking using a straw in a gable roof type paper container, a method of creating a straw insertion hole on a gable roof forming panel has been put into practical use (Patent Document 4). See), and a method of creating a straw insertion hole on the wife wall forming panel has not been put to practical use. However, when storing the rest of the contents without consuming all of the contents at once, it is more convenient to create a straw insertion hole on the wife wall forming panel because the straw insertion hole will not be exposed on the surface during storage. Is good.
Furthermore, when creating a spout and a straw insertion hole in a conventional brick-type paper container, using the scissors mark (printed) as a guideline, the part is actually cut using scissors, Conventional types of plastic inserts in the straw insertion part, mostly with lids, have been put into practical use, but without the use of a jar, they can be opened manually to insert spouts and straws. The mechanism for creating holes is not known.

On the other hand, paper containers for beverages are generally manufactured by assembling a packaging material that has a laminated structure consisting of multiple layers by laminating a paperboard base material with resin or metal foil in a laminated form. In preparation for drinking the contents by inserting a straw into a container, the straw can be easily inserted by assembling using a packaging material with perforations and cuts on the paperboard substrate where the straw is inserted in advance. Although it has been devised so that it can be inserted (see Patent Document 5), there is no known application that the perforated or cut portions are easily broken by hand.
In addition, paper containers shampoos, gargles, oils, liquid detergents, granular detergents, etc. that are currently used for the storage of beverages have not been applied to the storage of liquids and particulate substances other than beverages. .
