Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to an easy-to-open paper bag that has an opening string attached along the edge of the bag.

BACKGROUND ART Conventionally, paper bags have been widely used in which a string is attached along the edge of the bag to open the bag without using a knife or the like, and the bag can be opened using the string.

Problems that the invention aims to solve: However, the paper bags that have been widely used in the past and are equipped with the above-mentioned opening string usually have an extra length than the sealing band that is attached to the edge of the bag in a V-shaped cross section. It has a string attached. Therefore, when packing this type of bag, the strings in the extra length that protrude from the bandage get tangled with each other, making it difficult to unpack and pull up each bag individually, as well as making it difficult to insert the strings. In some cases, an extremely large amount of force is required, and the current situation is that the force of pulling the string may injure the fingers or is difficult to pull up easily. The present invention relates to a technology developed in view of many of these conventional problems.

Means for Solving the Problems The easy-to-open paper bag of the present invention, which eliminates the above-mentioned various defects, is a paper bag equipped with a tear string, and has a tear strip attached to the edge of the bag in a V-shaped cross section. The present invention relates to an easy-to-open paper bag that has no protruding strings and is formed so that the strings can be pulled up very easily.

An example of its implementation will now be described in detail in conjunction with the drawings.

Figure 1 shows a conventionally widely used paper bag with a string attached to the rim for opening the bag. One end of the string is made to protrude.

The present invention is an improvement on this, and has a length in which the mouth edge 4 of the cylindrical body 3 straddles both the cylindrical walls 5, 5, and has a V-shaped cross section, leaving extra length portions 6, 6 at both ends of the cylindrical width. A band 7 is pasted 8, and a cut edge 9 is cut in the vertical direction from the upper end of one extra-length portion 6 of the band 7, along a fold line 10 that forms the band 7 into a V-shaped cross section. An opening string 11 slightly longer than the width of the tube is attached to the bag, and the end of the string 11 and the end of the cut line 9 are connected 12 to form an easy-to-open paper bag of the present invention.

Function Since the present invention is as described above, when using it, it is necessary to
By twisting the end outward, the extra-length portion is pulled apart from the score line, and the end of the extra-length portion is thus released and becomes a knob piece as shown in FIG. 7. However, by pulling up this tab, an opening string is attached along the break line of the envelope, and the end of the string is connected to the tab, so that the band can be opened along the crease line. It is torn and the article can be easily removed by the weight of the contents.

Effects Therefore, the easy-to-open paper bag of the present invention is more effective than the conventional paper bag in which the opening string protrudes from the extra length of the envelope.
One end of the opening string is built into the seal, so
No strings get tangled like with conventional products. Therefore, it is possible to pack the bags in an orderly manner, and also to peel off each bag smoothly. Further, since one end of the opening string is connected to the score line, the package can be opened easily by connecting the score line and the opening string without requiring an extremely large force as in the conventional case. Therefore,
Since the envelope can be easily opened, it is possible to completely prevent foreign substances such as paper dust and adhesive layers from getting into the contents. However, in the bag of the present invention, the inner bag is a synthetic resin bag, the upper and lower openings are sealed by heat sealing, the outer bag is a paper bag, and the inner bag and outer bag can move freely relative to each other.
It is very suitable for bags that can be taken out without breaking the seal of the inner bag.

Claims (1)

[Scope of utility model registration request] A long band with a V-shaped cross section and an extra length at both ends of the tube width is provided across both cylinder walls at the mouth edge of the cylindrical body, and from the upper end of one of the extra measures of this band. This easy-to-open paper bag is made by cutting the score line, attaching an opening string along the fold line forming a V-shaped cross section, and connecting the end of the string to the end of the score line.
