Abstract

PURPOSE: To remove a rough feel at the contact face when directly putting the unsealed opening of a paper pack to one's lips to drink milk or the like, by forming a notch or a score for folding the edge with a part left with a belt-form width from the edge, at two positions separated from each other, in the first belt-form sticking part. CONSTITUTION: Diagonal notches 3 are formed from both edges of the first belt-form sticking part 2 of the first side wall 16. The front end is positioned at the upper part than the folding lines 12 at the edges. A paper pack 8 provided with the notches in advance in this way, is sealed in the same way with conventional packs. In this way, after the sealed part of paper pack has been opened, a pair of notches can be folded back outward and the outflow opening edge of liquid in the paper pack can be formed smooth. Accordingly, when directly putting the opening edge to one's lips to drink the inside liquid, the feel on one's lips becomes better.

成のために次の構成をとる。In such a medium-sized or larger paper pack container, there is a case where it is desired to directly drink milk or the like by opening a rhombic opening. At this time, since the opening edge is originally peeled off from the bonded portion, the outer surface of the edge of the opening is a rough peeled surface. Therefore, when the lips are attached to the lips, there is a disadvantage that it gives a rough contact feeling and becomes uncomfortable. Therefore, the present invention has an object to provide an opening mouth portion which does not have a rough feeling at the contact portion when the milk is directly attached to the opening mouth of the paper pack, and the following configuration is provided for achieving the object. To take.

FIG. 2 shows a state in which the adhesive portion is peeled off, and FIG.
FIG. 3 is an enlarged view of a main part of the opening edge of the above. 3 shows the first preparation state of the opening order of the present invention, and FIG. 4 shows the second preparation state. FIG. 5 is an explanatory diagram of the usage state. The paper pack 8 of this embodiment is a container for juice, milk, or the like, and is formed in a box shape. The upper end of the paper pack 8 is bent along a bending line 10, and the entire upper part is joined into a mountain-shaped roof. It is a thing. The height of the upper ends of the first side walls 16 facing each other is formed lower than the height of the upper ends of the second side walls 17 facing each other in advance. And the first side wall 16
The band-shaped first bonding portion 2 is formed on the outer surface of the upper edge of the first side, and the band-shaped second bonding portion 4 is formed on the inner surface of the upper edge of the second side wall 17. Further, an inverted V-shaped fold line 13 is previously formed in a valley fold at the upper end of the first side wall 16. At the same time, an edge fold line 12 for valley fold is also formed on the edge of the first bonded portion 2.

ることができる。On the outer surface of the upper end portion of the second side wall 17, a fold line for valley fold is formed at a position lower than the second bonded portion 4. Although not shown in FIG. 1, an oblique valley fold line is previously formed between the upper end of the second side wall 17 and the corners of the second side wall 17 and the first side wall 16. Here, the feature of the present invention is that slanted cuts 3 are formed at both edges of the strip-shaped first laminated portion 2 of the first side wall 16 and the tip thereof is located above the edge fold line 12 as well. Is located in. In this way, the paper pack 8 in which the notch 3 is formed in advance is joined in the same manner as the conventional paper pack.
In addition to the conventional adhesive portion, if only the range of the chain line which is the edge portion of the cut 3 in FIG. 2 is adhered to the contact portion 15 at the lower portion of the second bonding portion 4 as a precaution, the state before opening Thus, it is possible to more reliably prevent milk or the like from leaking from the cut 3 to the outside.

折り返されているため、人の口に接触することはない。When the package is opened, the joint around the cut 3 is naturally peeled off by opening as shown in FIGS. 1 and 2. Then, after opening, the first bonded portion 2 is slightly opened to the first side wall 16 side as shown in FIG. 1, and the first bonded portion 2 is bent outward as shown in FIG. 3 to form the bent portion 6. That is, the gaps 3 and 3 formed on both edges of the first bonded portion 2 are bent downward. At this time, the edge fold line 12 in FIG. 2 becomes the fold line of the fold portion 6 in FIG. At this time, the tip of the notch 3 is slightly opened downward so that the tip is cut at the edge fold line 12 in FIG.
May reach. Next, as shown in FIG. 4, the opening 1 is further opened toward the first side wall 16 to obtain a large opening. Therefore, as shown in FIG. 5, the bent portion 6 is brought into contact with the surface of the lips 9 of the person, and the paper pack 8 is tilted so that the liquid inside
11 can be poured directly into the mouth. In general, the inner peripheral surface of the paper pack 8 is covered with a waterproof film, which forms the covering surface 7, so that the outer surface of the bent portion 6 is a very smooth surface. On the other hand, since the adhesive on the back surface side of the bent portion 6 is peeled off, a rough joint peeling surface 14 is formed. However, since the roughened surface is folded back to the back side, it does not come into contact with the human mouth.

位置させることが可能となる。The opening of the paper pack according to the present invention is formed with the notches 3 and 3 for folding or the notches at the positions apart from each other in the first bonded portion 2 leaving a part in the width direction thereof. Therefore, after opening the joint portion of the paper pack, the pair of cut lines 3, 3 or the cutout portion can be folded back to the outside. Thereby, the edge portion of the liquid outlet of the paper pack can be formed smoothly. Therefore, when the internal liquid is drunk with the mouth directly attached to the lip, the contact feeling against the lips becomes good. Conversely, since the opening edge of the conventional paper pack is the adhesive peeling surface, the opening surface is rough, and when you touch the mouth with it and drink milk, juice, etc. inside, it is rough on the contact part of the mouth. Although the unpleasant touch is given, the unsealing opening of the present invention can eliminate such unpleasant contact. Then, the peeled first bonded portion 2 can be positioned on the back surface side of the contact portion.
