Detailed Description
The following describes details and operational principles of embodiments and examples of the present invention with reference to the drawings. The paper bag comprises surface paper, wherein one side end of the surface paper is provided with an adhesive surface 11, a vertically arranged inner folding line I9 is arranged between the adhesive surface and the surface paper, the adhesive surface is folded inwards along the inner folding line I, and the outer surface of the adhesive surface 11 is adhered to the inner surface of the other side end of the surface paper, so that a bag body with a closed peripheral surface is formed; referring to fig. 2, the first pocket surface 1, the first side surface 4, the second pocket surface 6 and the second side surface 8 are sequentially arranged on the surface paper, which means that the first pocket surface, the first side surface, the second pocket surface and the second side surface sequentially enclose a pocket body, so that the position of the adhesive surface is irrelevant, in fig. 6, the adhesive surface 11 is arranged at the right side of the second side surface 8, the adhesive surface is adhered to the first pocket surface 1, and if the adhesive surface 11 is arranged at the right side of the first side surface 4, the adhesive surface 11 is adhered to the second pocket surface 6. The folding line I2, the folding line II 5 and the folding line III 7 which are vertically arranged are sequentially arranged between the adjacent faces, namely the folding line I2 is arranged between the first bag face 1 and the first side face 4, the folding line II 5 is arranged between the first side face 4 and the second bag face 6, the folding line III 7 is arranged between the second bag face 6 and the second side face 8, the first bag face and the second bag face are equal in width, the first side face and the second side face are equal in width, the adjacent faces are folded along the folding lines, the first bag face 1, the first side face 4, the second bag face 6 and the second side face 8 enclose a paper bag cavity, and referring to the attached drawing 1, the X-axis direction is the left-right direction, the Y-axis direction is the front-back direction, and the Z-axis direction is the up-down direction. The lower ends of the first bag surface, the first side surface, the second bag surface and the second side surface are respectively extended with a first bottom surface 16, a first adhesive surface 21, a second bottom surface 22 and a second adhesive surface 26, the first bottom surface, the first adhesive surface, the second bottom surface and the second adhesive surface are not connected and can be independently folded, and the extension lengths can be the same or different; first bag face, first side, second bag face and second side and extend and have horizontal setting inside broken line two 17 between the face, and extend the face along inside broken line two folding, first bottom surface 16 and second bottom surface 22 are drawn together, first adhesive surface and second adhesive surface bond respectively in the left and right sides of the first bottom surface and the second bottom surface that draw together, the length of first adhesive surface and second adhesive surface is longer, and then the bonding is more firm, first bottom surface, second bottom surface, first adhesive surface and second adhesive surface form the bottom surface, and the bonding portion of the so fashioned bag body is in the bottom for the bag body surface is more pleasing to the eye.
A first crease line 3 is arranged at the vertical center position of the first side surface 4 and the second side surface 8, a second crease line 20 and a second crease line 23 are arranged at the transverse center position of the bottom surface, two ends of the second crease line 20 are outer crease lines, the middle part of the second crease line 23 is an inner crease line 23, bottom surface crease lines 18 which are obliquely arranged are arranged at two sides of the bottom surface, the bottom surface crease lines are inner crease lines, one end of each bottom surface crease line is connected to a bag corner of the bottom surface, the other end of each bottom surface crease line is connected to the outer crease line end of the second crease line, the bottom surface crease lines 18 and side edges 27 of the bottom surface form an isosceles triangle, and the left side and the right side of the bottom surface are bonded by a first bonding surface and a second bonding surface, so that the two layers are formed, and the bottom surface crease lines 18 are simultaneously appeared on the first bottom surface, the second; see figure 7, when the bag body is folding, first side 4 and second side 8 are along crease line 3 inwards folding, make both sides face fifty percent discount, because of first side and second side along crease line fifty percent discount to the end, make the bottom surface both sides along bottom surface crease line 18 and outer crease line 20 to central point and put foldingly, the bottom surface mid portion then follows interior crease line 23 fifty percent discount, that is to say mainly sets up in the bottom at the folding part of the bag body, not only the bag body surface does not shelter from, and the main bag face of the bag body does not have the crease line moreover, only has a vertical crease line in the side of the bag body, and the bag body is whole pleasing to the eye, the printing effect is good.
The first bottom surface and the second bottom surface are symmetrically arranged front and back along the transverse center line, so that the position of the second crease line is just between the first bottom surface and the second bottom surface; a second bonding surface 24 extends from the second bottom surface, the second bonding surface is bonded with the first bottom surface, and the second crease line 23 is arranged on the second bonding surface, so that the fastness of the bottom surface is improved; in order to make the bottom surface more beautiful, the outer surfaces of the first adhesive surface and the second adhesive surface are adhered to the inner surface of the bottom surface, the inner surface of the second adhesive surface is adhered to the outer surface of the first bottom surface, and the first adhesive surface 21 and the second adhesive surface 26 are hidden in the box body, so that the integrity of the bottom surface is better.
Folding-preventing notches 19 are formed in two ends of the first adhesive surface and the second adhesive surface, so that the first adhesive surface and the second adhesive surface cannot rub and collide with the first bag surface and the second bag surface when being folded, and the forming effect is better; similarly, the upper end and the lower end of the bonding surface are provided with chamfers 12, the chamfers are arranged to prevent the two ends of the bonding surface from colliding with other surfaces or overlapping with other surfaces, the thickness of the overlapped surfaces is increased, the height after folding is affected, and the problem is avoided after the chamfers are arranged at the upper end and the lower end of the bonding surface. The sack of first pocket face and second pocket face all is equipped with stringing hole 15 for the processing of portable rope, the handbag need improve the intensity of sack, the upper end of facial tissue is extended there is the sack to strengthen face 13, the facial tissue has horizontal interior broken line three 14 that set up with strengthening between the face, it is interior folding along interior broken line three-dimensional to strengthen the face to with facial tissue internal surface bonding, the intensity of sack can be strengthened to the double-deck setting of sack.
