Description

  The present invention relates to a string-binding paper bag whose opening can be closed with a string that serves as a handle (handle) or a shoulder string (shoulder strap).

  Conventionally, handbag-type or shoulder-type paper bags have been widely used as shopping bags.

  This type of paper bag includes a square bottom bag made from one base paper and two strings attached to the square bottom bag. The square bag is a cylindrical shape formed by a front part and a back part facing each other, a gusset part connecting each side edge of the front part and the back part, and a front part, a back part and a gusset part. And a bottom portion that closes one end of the body, and the other end of the cylindrical body forms an opening for putting articles into and out of the square bottom bag. Two holes are formed at intervals in the width direction at each of the front and rear end portions on the opening side. Both ends of one string are passed through the two holes from the outside of the square bottom bag. And each knot is attached to the square bottom bag by making a knot that prevents the string from coming out from the hole at both ends.

  Depending on the length of the string, it will be a handbag-type or shoulder-type paper bag. That is, when the length of the string is short, the two strings become grips, and the two strings can be grasped by hand and the paper bag can be carried by hand. When the length of the cord is long, the two cords become shoulder straps, the two cords can be hung on the shoulder, and the paper bag can be carried by the shoulder strap.

  However, even if it is a hand-held type or a shoulder type, when carrying a paper bag, the opening of a square bottom bag will open. Therefore, the articles in the paper bag (square bottom bag) are fully visible from the surrounding people. In addition, there is a possibility that a hand is put into the paper bag through the opening, and an article in the paper bag is stolen. Further, if an article wider than the width of the gusset portion is placed in the paper bag, when the paper bag is placed on the floor or the like, the opening may spread and the paper bag may fall down. In order to prevent these problems, there are cases where measures are taken such as fastening the front and back parts with tape, or fastening two strings with tape, but it makes no sense if the tape is peeled off or torn. End up.

  Therefore, the inventor of the present application has previously proposed a string binding paper bag whose opening can be closed with a string. In the string binding paper bag according to this proposal, as shown in FIG. 7, two inner holes 94 and 95 are spaced in the width direction at each of the end portions on the opening 93 side of the front portion 91 and the back portion 92. And the locking holes 96 and 97 are formed at intervals on the outer side in the width direction with respect to the inner holes 94 and 95.

  One end of one string (first string) 98 is passed through the locking hole 96 of the front portion 91 from the outside, and a knot 99 that prevents the locking hole 96 from coming off is formed at one end of the string 98. Is attached to the square bottom bag 100. The other end of the string 98 is connected to the inner hole 94 adjacent to the locking hole 96 from the outside, the inner hole 94 of the back surface 92 from the inside, and the inner hole 95 of the back surface 92 from the outside. After passing through the inner hole 95 from the inner side and the locking hole 97 adjacent to the inner hole 95 in this order from the outer side, a knot 101 that prevents the locking hole 97 from coming off is formed at one end thereof. The other end of 98 is attached to the square bottom bag 100.

  Further, one end of another single string (second string) 102 is passed from the outside through the locking hole 96 of the back surface portion 92, and a knot 103 that prevents the locking hole 96 from coming off is formed at one end thereof. Thus, one end of the string 102 is attached to the square bottom bag 100. Then, the other end of the string 98 is connected to the inner hole 94 adjacent to the locking hole 96 from the outside, from the inner side to the inner hole 94 of the front part 91, and from the outer side to the inner hole 95 of the front part 91. After passing through the inner hole 95 from the inside and the locking hole 97 adjacent to the inner hole 95 in this order from the outside, a knot 104 that prevents the locking hole 97 from coming off is formed at one end thereof. The other end of 102 is attached to the square bottom bag 100.

  When the string binding paper bag is used, the opening 93 of the square bottom bag 100 is opened, and an article is put into the square bottom bag 100 through the opening 93. Thereafter, when the portion extending between the inner holes 94 and 95 in each of the strings 98 and 102 is pulled out to the outside, the portion between the inner hole 94 and the locking hole 96 in the front portion 91 and the inner hole 95 are The portion between the locking hole 97 is pulled toward the back surface portion 92, and the portion between the inner hole 94 and the locking hole 96 in the back surface portion 92 and the inner hole 95 and the locking hole 97 are The portion between the two is pulled toward the back surface 92 side. As a result, the edge on the opening 93 side of the front portion 91 and the edge on the opening 93 side of the back surface portion 92 are close to each other, and the opening 93 is closed. Thereby, the opening 93 can be closed without using a tape.

  However, since the strings 98 and 102 extend between the two inner holes 94 and between the two inner holes 95 in the state in which the opening 93 is opened, the strings 98 and 102 are used for the article into the square bag 100. There is a risk of getting in and out.

  The objective of this invention is providing the string binding paper bag which can prevent the 1st string and the 2nd string from becoming an obstacle of putting in and taking out articles into the square bottom bag.

  In order to achieve the above object, a string binding paper bag according to one aspect of the present invention includes a square bottom bag, a first string and a second string attached to the square bottom bag, The front part and the back part that face each other, the first gusset part that connects each side edge in the width direction of the front part and the back part, and the other side edge in the width direction of the front part and the back part are connected. A first gusset and a second gusset for connecting the second gusset, the width direction one side edge and the other side edge of the front face and the back face, respectively, the front face, the back face, and the first gusset part And a bottom part that closes one end of the cylindrical body formed by the second gusset part, and the other end of the cylindrical body forms an opening for taking in and out articles into the square bottom bag, The first insertion hole and the second insertion hole are formed at the opening and the rear part at intervals in the width direction at the opening side end, A first locking hole and a second locking hole are formed at a distance from the first insertion hole and the second insertion hole, respectively, and each of the first gusset portion and the second gusset portion has an opening side. Extends from the center of the edge toward the bottom, branches into two in the middle, and each branched portion has an inverted Y shape extending toward the corner of the bottom, and the front and back portions overlap the square bottom bag. The first intermediate hole and the second intermediate hole are bored in this order from the front side at the end on the opening side, and the first string is The first insertion hole of the front part, the first intermediate hole and the second intermediate hole of the first gusset part, and the first insertion of the rear part from the outside of the square bottom bag) The other end side is inserted into the hole and the first locking hole in this order from the outside of the square bottom bag, the second insertion hole in the front portion, the first middle of the second gusset portion And the second intermediate hole and the second insertion hole and the second locking hole on the back surface in this order, and the first locking hole and the second locking hole on the back surface are respectively inserted into the one end portion and the other end portion.

  As mentioned above, although one Embodiment of this invention was described, this invention can also be implemented with another form.

  For example, the first locking hole 33 and the second locking hole 34 are formed at intervals on the left side of the first insertion hole 31 and the right side of the second insertion hole 32, respectively. Instead, the first locking hole 33 may be formed on the right side, the upper side or the lower side with respect to the first insertion hole 31, and the second locking hole 34 may be formed as the second insertion hole. It may be formed on the left side, the upper side or the lower side with respect to 32. Similarly, the first locking hole 43 and the second locking hole 44 are formed at intervals on the left side of the first insertion hole 41 and the right side of the second insertion hole 42, respectively. The first locking hole 43 may be formed on the right side, the upper side or the lower side of the first insertion hole 41 with a space therebetween, and the second locking hole 44 may be formed in the second insertion hole 41. The hole 42 may be formed on the left side, the upper side, or the lower side with a space therebetween.

  The first insertion holes 31 and 41, the second insertion holes 32 and 42, the first locking holes 33 and 43, the second locking holes 34 and 44, the first intermediate holes 51 and 61, and the second intermediate holes 52, 62 is not limited to a circular shape, but may have a shape other than a circular shape. For example, the first locking holes 33 and 43 and the second locking holes 34 and 44 are not limited to a circular shape, but have a longer diameter (for example, the first string) than the first locking holes 33 and the second locking holes 34. It is sufficient that the hole has a size that allows both the first string 3 and the second string 4 to be inserted and removed, such as an elliptical shape having a major axis that is at least twice the thickness of the third string 4 and the second string 4.

  The 1st string 3 and the 2nd string 4 are not restricted to a spindle string, For example, cloth strings, such as a flat cloth string, may be sufficient.

  Further, a portion straddling between the first insertion hole 31 and the second insertion hole 32 of the front portion 11 in the first string 3 and / or the first insertion hole 41 and the second portion of the back surface portion 12 of the second string 4. A resin tube having flexibility such as a vinyl tube may be externally fitted to a portion straddling the insertion hole 42. Thereby, when a person holds the resin tube or puts it on the shoulder, it is possible to suppress the force being concentrated on the hand or the shoulder, and to suppress the pain of the hand or the shoulder.

  The end portions on the opening 16 side of the front surface portion 11, the back surface portion 12, the first gusset portion 13, and the second gusset portion 14 may be folded back inside the square bottom bag 2. In this case, a cardboard (mouth ball) such as cardboard may be disposed inside the folded portions of the front portion 11 and the back portion 12. It is preferable that both ends of the force paper extend outside the first locking holes 33 and 43 and the second locking holes 34 and 44. Thereby, when the opening 16 is closed, deformation | transformation of each edge part by the side of the opening 16 of the front part 11 and the back part 12 can be suppressed, and the opening 16 can be closed more favorably. Moreover, the deformation | transformation of the said periphery by the force added to the periphery of the 1st locking holes 33 and 43 and the 2nd locking holes 34 and 44 from the 1st string 3 and the 2nd string 4 can be suppressed.

  In addition, various design changes can be made to the above-described configuration within the scope of the matters described in the claims.
