Description

  The present invention relates to a paper bag with an underlying string and an underlying string attaching device.

  In the case of making a bag with a lanyard, generally, a configuration is adopted in which the opening of the bag is folded inward to form a tying portion (folding portion), and the laying cord is attached to the folding portion. Specifically, for example, after a thick sheet of paper (basket) is usually placed inside the tying part, a total of four holes, two on the left and right sides, are opened at predetermined positions in the tying part. After making two pairs of holes and inserting both ends of the lowering string cut into a predetermined length into the two holes of each group, make knots at the ends of the both ends of the lowering string to prevent it from coming out of the hole I am doing so. In the prior art, as described above, the work of making the straps on the bag is performed manually.

  Here, in the bag made as described above, the knot at the tip of the strap is protruding from the inner surface side of the bag, so when this knot is put into the hand or product inside the bag There is a possibility of getting scratched. That is, when the laced cord is, for example, a chemical woven cord, that is, made of synthetic resin, a method of thermally cutting the cut end portion to prevent the leading end of the woven cord from coming off when cutting to a predetermined dimension. Is generally used, but the cut surface after the heat cut is changed to a hard plastic by heat and a sharp corner is generated in the cross section.

  On the other hand, when the strap is made of natural materials such as cotton, there is no change in quality due to heat cut, so there is no problem of scratching the hands and products that are put in and out of the bag as described above. Absent. However, in this case, the cross-section after cutting spreads in a state where the fibers are scattered, and it becomes difficult to put the end face of the string into the hole. Therefore, when performing the attaching part work, workability at the time of insertion into the hole is deteriorated. There was a drawback of cost.

  Therefore, a method such as enlarging the hole to make it easier to insert is adopted. In this case, the tip of the lowering string is likely to come off from the hole, so it is necessary to double the knot. There are disadvantages such as that it takes time and the knot is doubled and the knot becomes larger and the hand and the product are easily caught.

  In addition, a method for mechanizing the attachment work of the above-described lace is proposed. In this method, as shown in FIG. 13, a cord 63 repeatedly folded in a wave shape is sandwiched from both sides between a pair of thick paper sheets 61, and glued and fixed. The central portion of the cord 63a that is not sandwiched becomes a tie-down cord 65 that is gripped by the user's hand to form a tie-down cord structure 60 as shown in FIG.

  The laying cord structure 60 is produced by the following method, for example. That is, as shown in FIG. 13, between the rotating rollers 70 and 70 arranged in two upper and lower rows at predetermined intervals, the string 63 is continuously passed in a wavy manner as shown in the figure and between the upper and lower rotating rollers 70 and 70. A pair of cardboard sheets 61 and 61 are arranged so that the cord 63 continuously looped in a wavy shape is sandwiched from the front and back sides, and the cord located in the middle portion of the corrugated sheet is fixed with an adhesive. To do. Then, the cardboard sheets 61 are alternately cut by the cut lines 62a at the center portions of the respective rotating rollers 70 and 70, and the center portion of the cardboard sheet 61 is divided into two vertically by the slit lines 62b formed in the horizontal direction. In this way, there is obtained a substituting string structure 60 in which both ends of a semicircular substituting string 65 are bonded and fixed with cardboard pieces 61a (see Patent Document 1).

  Moreover, when making the bag with a lanyard using the lanyard string structure 60, various methods are used. For example, as shown in FIG. 15, a paper bag 70 with a strap is formed by a method in which the strap string 60 is attached to the inside of the opening 72 of the bag body 71. In this case, the upper end of the opening 72 of the bag body 71 remains cut and is not folded inward.

Alternatively, as shown in FIG. 16, the underlying string structure 60 is formed by a method of concealing the underlying string structure 60 by the folding portion 73 in which the opening end is folded inward after the underlying string structure 60 is attached to the opening 72 of the bag body 71. There is a bag 70a with a lanyard (see Patent Document 2). In the latter case, for example, first, the lower cord structure 60 is bonded to a predetermined position of the opening 72 of the bag main body 71, and then, as shown in FIG. A configuration is adopted in which an open end of the bag main body 71 is folded inward so that a slashed piece 74 having a shape or a reverse J-shape is provided so that the slatted string 65 of the slatted string structure 60 can pass therethrough.
Japanese Patent Laid-Open No. 10-23916 JP-A-7-149354

  However, in the configuration shown in FIG. 15 described above, since the underlying string structure 60 inside the paper bag 70 is exposed, the appearance is poor and the design is not good. For this reason, the use to a high-class bag is difficult and the restriction | limiting that it can be used only for a comparatively cheap bag arose. In the case of the configuration shown in FIG. 16 described above, the underlying string structure 60 is hidden by the folding portion 73 and cannot be seen. However, when the opening end is folded inward, it is difficult to completely bond the J-shaped or inverted J-shaped cut portion 74, and the appearance is poor.

  In addition, since the portion of the cut portion 74 is slightly lifted due to poor adhesion, there are inconveniences such as hand or product being caught and torn when taking out the product stored in the bag. There is a method of applying a large amount of adhesive for complete adhesion, but in this case, the adhesive protrudes from the adhesive surface of the notch 74, and the bag sticks to the inside due to the protruding adhesive.

In the case of the conventional configuration, there is a problem that the material of the lanyard is limited to a relatively hard material that is difficult to extend. This is because when the tie strap is soft, for example, when the tie strap structure formed by attaching the lace first is attached to the opening and the bag making process is performed, the tie strap hangs from the strap string structure. This is because there is a problem that the hanging string may be caught between rollers of the machine or may be caught by other machine parts when the bag body is rotated.
It is an object of the present invention to provide a paper bag with an underlying string and an underlying string attaching device that eliminates the problems as in the above-described conventional configuration and does not limit the material of the string to be used.

  The invention of claim 1 has both side surface portions and front and back portions each having a folding fold 9a in the middle in the vertical direction, and horizontally in the lower portion of either the front portion or the rear surface portion. The string attaching plates 12 and 12 are respectively provided on the upper and lower portions of the folding line 9 formed in the horizontal direction along the inner surface of the end of the opening of the bag body 7 having the folding fold 9b and having the opening 8 at the upper end. A pair of string-passing holes 13 and 13 are provided in the folding part 10 formed by bonding and fixing, and the opening end part is bent inward, and both ends of the laying string 14 formed to a predetermined length are inserted into the string-passing holes. Then, it is characterized in that it is bonded and fixed between the string attaching plates 12 and 12. Further, a string attaching plate 12 to be bonded to each of the inner surfaces of the upper and lower portions of the folding line 9 provided along the inner surface of the end portion of the opening 8 is integrally formed, and a double fold line is provided at an intermediate portion of the string attaching plate. Also good.

  Therefore, in the present invention, the opening 8 provided at the upper end of the bag body 7 is folded inward to provide the folding portion 10, and is attached to the upper inner surface of the bag body and the inner surface of the folding portion and is made of cardboard and has strength. 12 and 12 are formed by pulling out the hand straps 14 and 14 bonded and fixed to the inside of the bag main body, so that the surface of the bag main body is formed in a smooth flat shape and the end of the hand strap is formed. Can be inconspicuous. Further, the material of the laid string is not limited, and for example, a soft string or a ribbon-shaped string can be used.
