DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag used for storing a bag suitable for storing foods such as confectionery or the like, medicines, cosmetics, etc., and more particularly to a snack confection or a fragile biscuit. The present invention relates to a bag suitable for storing confectionery and the like.

[0002]

2. Description of the Related Art Conventionally, a rigid paper box is generally used as a package for storing fragile contents, and when storing food and the like in a tray or tray in consideration of hygiene. A tray with a lid seal is inserted, and a paper box is wrapped with a moisture-proof cellophane with a tearing tape. On the other hand, when a rigid package is formed using a bag, a molded product such as a tray is usually placed inside the bag.

[0003]

However, in recent years, it has been required to save packaging materials from the viewpoint of resource saving and reduction of garbage, and accordingly, there has been a tendency to reduce the number of members used for packaging. However, in the case of a paper box, in consideration of hygiene, the tray is inserted as described above, and the paper box is wrapped with a film, so that such a requirement cannot be satisfied. Therefore, it is sufficient that foods and the like can be directly packaged in the bag, but the bag has poor rigidity, and thus it is necessary to put a tray as described above. In addition, the bag is generally torn open after being torn, so that there is a problem that the opening operation is troublesome and the bag cannot be opened and closed like a paper box.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to provide a bag which has a certain degree of rigidity, is easy to open, and has a resealability after opening. Is to provide the body.

[0005]

In order to achieve the above object, a bag according to the present invention comprises a sheet material mainly composed of paper and having a heat-sealing resin layer in the innermost layer, and has gussets on both sides. A laterally-placed bag formed in a shape having a vertical seal portion stuck on the upper surface and end seal portions at both ends, wherein the vertical seal portion has two cuts at an interval that can be gripped by a finger. is provided, it extends to spread each consecutive two cuts of the vertical seal portion on the upper surface portion of the larger 2

[0006]

The bag having the above-described structure has a form in which ridges are formed by gussets on both sides, and the ridges serve to provide rigidity to the bag. In addition, a portion between the two cuts provided in the vertical seal portion serves as a grip portion when the opening area on the upper surface is opened along the perforation, and as a stopper so as not to float when the opening area is closed. Function.

[0007]

FIG. 1 is a perspective view showing a bag as an embodiment of the present invention. This bag is formed by making a sheet material punched into a developed shape shown in FIG.

The sheet material S is mainly composed of paper and has a resin layer for heat sealing in the innermost layer. The procedure for making the sheet material S into the bag body P shown in FIG. 1 will be described. First, the side portions 12, 13 on the left and right sides of the bottom portion 11 are respectively folded along the folding lines a, b, c and d, e, f. And then folded inward to form a gusset, and the smaller upper surface 1
4, the folded portion 14a is folded outward,
This portion is heat-sealed in a state of being superimposed on the inner surface of the left end of the larger upper surface portion 15 to form the vertical seal portion 1 stuck together. Next, one of the end portions 16 is heat-sealed to form the end seal portion 2 to be in a closed state. Then, in the filling process, the side portion 1
The whole of the gussets 2 and 13 is spread out to form a square tube, the contents are filled from the open end 16, and the end 16 is heat-sealed and closed. Thereby, the bag body P having the shape shown in FIG. 1 is formed. The bag body P formed in this manner is expanded by expanding the gussets on both side surfaces 3.
The ridgeline α of the book is formed, and therefore, has some rigidity.

As shown in FIG. 2, the sheet material S is provided with a cut 5 and a perforation 6 in a portion that becomes the upper surface 4 of the bag body P in the larger upper surface portion 15. That is, two cuts 5 are provided at substantially the center of the portion forming the vertical seal portion 1 at intervals that can be gripped by a finger, and the perforations 6 are each cut 5
Are provided so as to extend continuously from each other. As shown, the perforation 6 comprises a straight portion 6a continuous with the cut 5 with a jumpsuit, and a plurality of V-shaped portions 6b continuous therewith. The first U-shaped portion 6b adjacent to the linear portion 6a is the linear portion 6b.
a, and is formed so as to protrude inward by one head, and the second and subsequent U-shaped portions 6b are arranged such that the cutting end on the downstream side is larger than the cutting rear end on the upstream side when viewed in the spreading direction. It is formed so that one head protrudes. In this embodiment, a linear streak push 7 is provided in a state where the end portions of the perforations 6 are connected. Each cut of the perforation 6 penetrates only the layer other than the heat-sealing resin layer in the sheet material S, thereby providing the bag body P with a barrier property and along the perforation 6. It can be broken.

In the folded portion 14a of the smaller upper surface portion 14, cuts 8 and perforations 8a are provided in two rows at positions corresponding to the cuts 5 and the linear perforations 6a, respectively. An auxiliary cut 9 and a perforation 9a are provided at a slight interval. Further, an arc-shaped perforation 10 is provided on the upper surface portion 14 so as to connect the inner ends of the perforations 8a located inside. Each cut of the perforations 8a, 9a and perforation 10 is in a state of penetrating only the layers other than the heat-sealing resin layer in the sheet material S as in the case of the above-described perforation 6.

Since the sheet material S is configured as described above, the bag body P made by forming the bag as described above is gripped by a finger at substantially the center of the vertical seal portion 1 as shown in FIG. At two possible cuts 5 (a cut 8 is located substantially on the back side) at a possible interval and a continuous linear perforation 6a (a perforation 8a is located substantially on the back side) with a jumper on the cut 5 Is provided with an opening area 4a partitioned by two rows of perforations 6 (6b) extending so as to be continuous with the cuts 5, respectively. Therefore, two breaks 5
After the vertical seal portion 1 is broken by pulling with a finger as a knob portion 17 between the portions, the portion of the perforation 10 is broken by pushing with the tip of the thumb or by pulling it as it is and pulling it obliquely upward as shown in FIG. As shown in FIG. 7, the opening area 4a can be opened by breaking along the perforation 6 to the portion of the streak push 7. Further, the bag body P can be closed by inserting the knob portion 17 at the tip of the opening area 4a below the portion broken at the perforation 10.

In the above embodiment, the case where the cuts 5, 8, and 9 are provided in advance in the sheet material S has been described. It may be formed by the following. Also,
By providing a plurality of the knobs 17 and the unsealing area 4a connected thereto, it is also possible to adopt a form that can be opened by a plurality of parts.

Hereinafter, the present invention will be described in detail with reference to specific examples.

b) After forming 8a, 9a, and 10, a layer of PE (40 μm) was provided on the inner surface by extrusion coating to close all cuts. The cuts 5, 8, and 9 were formed by performing a cutting process in a penetrating state during bag making.

[0017]

As described above, the bag of the present invention is
Since the gussets on both sides provide a ridge line like a box, the contents can be protected by exhibiting some rigidity. In addition, the upper surface can be easily opened by pulling a part of the vertical seal portion as a knob, and the knob is broken at an arc-shaped perforation.
It can be re-sealed with Rukoto be inserted below the. Therefore, the bag alone can replace the conventional packaging, and can meet the demand for reducing packaging materials.
