For example, it can set to 5 mm-15 mm. The welding width w2 of the left and right side welding parts 26 and 27 can be set arbitrarily, but can be set, for example, 5 mm to 10 mm so as not to break the bag when the measuring pouch 1 is dropped or the like. Furthermore, although the welding width w3 of the dividing line 55 can be arbitrarily set, in order to fill the content C from the storage chamber 50 to the measuring chamber 51 when the measuring pouch 1 is dropped or by manually pressing the main body 20 For example, it can be set to 15 mm to 30 mm so as not to be damaged when it is cut.

  The maximum width between the left and right inner edges of the main body 20 (in the present embodiment, the same dimension as the width W1 between the inner edges of the main body 20 at the lowermost end P1 of the bottom dividing line 56) can be set to 100 mm to 300 mm, The maximum height H between the upper and lower inner edges can be set to 150 mm to 400 mm. The full volume of the storage chamber 50 can be set to 200 ml to 2000 ml, and the full volume of the measurement chamber 51 can be set to 10 ml to 400 ml.

  The height H1 of the lowermost end P1 of the bottom dividing line 56 with respect to the lowermost end of the lower inner edge of the main body portion 20 can be set to 100 mm to 300 mm in order to sufficiently secure the internal volume of the storage chamber 50.

  The ratio W2 / W1 of the width W1 between the inner edge of the main body 20 at the lowermost end P1 of the bottom parting line 56 and the width W2 from the lower end P1 of the bottom parting line 56 to the left inner edge of the main part 20 is It can be set to 25% to 75%. By this configuration, as shown in FIG. 1 and FIG. 2, the lower end portions of a pair of conical waist-break preventing spaces 33, 34 extending upward continuously to the upper portions of the left and right portions of the storage chamber 50. Can sufficiently prevent the waist of the weighing pouch 1 from being broken. However, the lowermost end P1 of the bottom parting line 56 is a bottom parting line 56C shown in FIG. 8C so that the left and right hook portions 35, 36 and the left and right hook part base portions 37, 38 are formed substantially mirror-balanced. As in the middle of the width direction between the inner edges of the main body 20 or in the vicinity thereof (ratio W2 / W1 is 40 to 60%), the position of the intersection point P3 is set as high as possible. Preferably, the height is as high as that of the right-hand horn 36.

  Bottom edge of bottom division line 56 and lower left edge of body portion 20 relative to bottom end P1 of bottom division line 56, height H2 of upper end P2 of side division line 57, and bottom end P1 of bottom division line 56 The ratio H3 / H2 of the intersection point P3 with the height H3 of the intersection point P3 can be set to 15% to 85%. By configuring in this manner, the length in the vertical direction of the first waist-fold-break preventing space 33 in the pyramid shape extending continuously upward to the upper portion of the left side portion of the storage chamber 50 is sufficiently secured, It can be effectively prevented.

  The opening width W3 on the storage chamber 50 side of the communication passage 52 can be set to 15% to 30% of the width W1 between the inner edges of the main body 20 at the lowermost end P1 of the bottom dividing line 56. By configuring in this manner, the content C is supplied from the storage chamber 50 to the measuring chamber 51 with a small pressure, while ensuring a sufficient volume of the measuring chamber 51 and a sufficient width of the communication passage 52. It becomes possible. Although the opening width W3 is obtained by the distance between the lower end P4 of the right side edge of the side parting line 57 and the inside edge of the right side of the main body 20, as shown in FIG. 9A, the bottom parting line 56 In the case where the side division lines 57 are connected by the connecting portion 58 having a circular arc shape or the like, the center of the arc on the outer peripheral side of the connecting portion 58 is set to the lower end P4 and determined.

  The width W4 of the smallest portion of the passage width of the communication passage 52 can be set to 50% to 90% of the opening width W3 of the communication passage 52 on the storage chamber 50 side. With this configuration, it is possible to supply the content C from the storage chamber 50 to the measuring chamber 51 with a small pressure.

  The length L1 of the communication passage 52 can be set to 100% to 200% of the opening width W3 of the communication passage 52 on the storage chamber 50 side. According to this configuration, it is possible to appropriately set the volume of the storage chamber 50 and the volume of the measurement chamber 51 while configuring the content C to be able to be supplied from the storage chamber 50 to the measurement chamber 51 with a small pressurizing force. The length of the communication passage 52 is set to the distance in the vertical direction between the upper end P2 of the side dividing line 57 and the lower end P4 of the side dividing line 57.

  The distance L2 between the upper end P2 of the side parting line 57 and the inner upper edge of the main body 20 can be set to 50% to 100% of the opening width W3 on the storage chamber 50 side of the communication passage 52. With this configuration, the movement resistance of the content C from the communication passage 52 to the measuring chamber 51 can be reduced, and the content C can be supplied from the storage chamber 50 to the measuring chamber 51 with a small pressure. Become.

  When assembling the weighing pouch 1, for example, the front portion 21 and the rear portion 22 are welded in a state where the rectangular film material is folded so that the middle portion becomes substantially W-shaped by a bag making machine. The lower welding portion 31 and the left and right side welding portions 26 and 27 are formed. Next, with the spout welding machine, the wedge portion 11 of the spout 10 is disposed between the upper end portions of the front face portion 21 and the rear face portion 22, the front face portion 21 and the wedge portion 11, the rear face portion 22 and the wedge portion 11 Are respectively welded, and the spout 10 is attached to the main body 20. Next, the supply pipe of the content C is inserted from the upper side of the main body 20 by the filling machine, the storage chamber 50 is filled with the content C of a predetermined volume, and after filling, the upper welded portion 24 of the main body 20 And the dividing line 55 are to be welded and assembled. In addition, after filling the contents C, preblowing from the spout 10 into the main body 20 is performed, and the air supplied into the main body 20 slightly inflates the main body 20 to squeeze the measuring pouch 1 to pour the contents C It can also be configured to facilitate the task of releasing.

  When the contents C are poured out from the measuring pouch 1, first, as shown in FIG. 7A, the measuring pouch 1 is made to face sideways so that the communication passage 52 side is on the lower side. In this state, the content C is filled in the conical second waist-break preventing space 34 formed around the lower end of the communication passage 52, but the communication passage 52 on the upper welded portion 24 side is a front surface portion The film material which comprises 21 and the back surface part 22 is piled up without substantially clearance gap, and the movement of the contents C to the measuring chamber 51 side is regulated.

  Next, as shown to FIG. 7B, the part corresponding to the storage chamber 50 of the main-body part 20 is pressurized by hand. At this time, the tip end of the conical second waist-break preventing space 34 formed around the lower end of the communication passage 52 sequentially moves toward the upper welding portion 24 side, the passage area of the communication passage 52 is enlarged, and the comparatively small The content C in the storage chamber 50 can be filled into the measuring chamber 51 by force. Further, while looking at the scale 53 formed on the front face portion 21 corresponding to the measuring chamber 51, a desired amount of internal volume is filled into the measuring chamber 51.

  Next, as shown in FIG. 7C, after the measuring pouch 1 is vertically rotated and the cap 13 is removed, as shown in FIG. 7D, the measuring pouch 1 is turned obliquely downward as shown in FIG. 7D. Sideways, the content C of the weighing chamber 51 is dispensed from the mouth 12.

  In the measuring pouch 1, when the storage chamber 50 is filled with the content C and the storage chamber 50 is expanded, as shown in FIG. 2, the upper portions of the storage chamber forming portions 21a and 22a in the front surface portion 21 and the rear surface portion 22. Since a pair of horns 35 and 36 in the form of a closed cross-section are formed on one side and a pair of horns base 37 and 38 in the cross-section chevron shape are formed, the strength near the bottom parting line 56 is enhanced. The disadvantage that the measuring pouch 1 is broken along the bottom parting line 56 is effectively prevented. In addition, since the waist breakage can be prevented only by adjusting the shape of the bottom part dividing line 56, the weighing pouch 1 can be manufactured at low cost without increasing the number of parts and the number of manufacturing processes. Further, when the content C in the storage chamber 50 is to be filled into the measuring chamber 51, the main body portion 20 is turned sideways with the communication path 52 side down, and in this state, the storage chamber 50 of the main body portion 20 is accommodated. The portion of the communication passage 52 can be easily expanded by using the tip end of the conical second waist-break preventing space 34 formed around the lower end of the communication passage 52 as the base end. Therefore, the content C in the storage chamber 50 can be filled into the measuring chamber 51 by enlarging the passage area of the communication passage 52 with a relatively small force.

Next, another embodiment in which the configuration of the main body 20 is partially changed will be described. However, the same reference numerals are given to the same members as those of the embodiment and the detailed description thereof will be omitted.
(1) As shown in FIG. 8D, the width of the upper welding portion 24 at the upper position of the upper end of the side parting line 57D is narrow, and the passage enlarged portion projects upward to the inner edge of the upper welding portion 24. 60 can be provided. With this configuration, the distance between the upper end of the side parting line 57D and the lower edge of the upper welding portion 24 can be increased, and the contents C can be smoothly sent out from the communication passage 52 to the measuring chamber 51. The passage expanding portion 60 can also be provided above the side parting lines 57, 57F other than the side parting line 57D.

(2) As shown in FIG. 8D, the wide portion 61 can be formed in the upper welding portion 24 on both sides of the wedge portion 11, and the wide passage 61 can form the guide passage 62 connected to the wedge portion 11. If such a guide passage 62 is formed, the contents C in the measuring chamber 51 can be poured out smoothly from the mouth 12.

(3) In order to facilitate the movement of the content C from the communication passage 52 into the measuring chamber 51, it is most preferable to form the side dividing lines 57 in an arc shape as described above, but in FIG. The side division lines 57D can also be formed linearly in the vertical direction, as shown by the side division lines 57D.

(4) As shown in FIG. 8D, the left side of the bottom parting line 56D may be spaced apart from the side welding part 26 as in the bottom parting line 56D. That is, even when the films constituting the front part 21 and the rear part 22 of the main body 20 are not welded, the films are overlapped without substantial gaps near the welded parts, and water tightness is secured to some extent . For this reason, the bottom parting line does not necessarily have to be continuously provided to the side welding part 26 on the left side of the main body 20, and the content C in the measuring chamber 51 leaks like the bottom parting line 56D shown in FIG. It is possible to provide a gap to the left side weld 26 in a range that does not exist. In this case, the content C is transferred from the storage chamber 50 to the measurement chamber 51 through the communication passage 52 while discharging the air in the measurement chamber 51 into the storage chamber 50 through the spaced portions only by tilting the measurement pouch 1. The content of the storage chamber 50 can be filled into the measuring chamber 51 without pressurizing the main body portion 20, which is preferable.

(5) As shown in FIG. 8E, in place of the bottom parting line 56, the bottom parting line 56E is provided with the left end spaced from the left side weld 26 and the left end of the bottom parting line 56E. The inclined portion 63 connected to the upper welding portion 24 on the left side of the wedge-shaped portion 11 is provided in the portion to weld the front portion 21 and the rear portion 22 and guide the contents C in the measuring chamber 51 to the spout 10 side It can also be configured.

(6) As shown in FIGS. 9A and 9B, a check valve which permits only the movement of the content C from the communication passage 52 to the measuring chamber 51 between the upper end portion of the side dividing line 57 and the upper welding portion 24. 64 can also be provided. In this case, the contents C in the measuring chamber 51 can be prevented from flowing backward to the storage chamber 50 side. In addition, since the air in the measuring chamber 51 can be prevented from flowing into the storage chamber 50 side, the deterioration of the contents C due to the contact with the air can be prevented.

(7) As shown in FIG. 10, instead of the side parting line 57, the side parting line 57F is disposed in an inclined manner so that the opening width of the communication passage 52 becomes larger toward the upper side. The width W5 between the upper end P2 of the dividing line 57F and the inner edge on the right side of the main body 20 can be set to 130% to 170% of the opening width W3 on the storage chamber 50 side of the communication passage 52. According to this structure, the movement of the content C from the communication passage 52 to the measuring chamber 51 can be promoted, and the content C in the storage chamber 50 can be filled into the measuring chamber 51 with a smaller force. it can.
For example, in the measuring pouch 1 shown in FIG. 10, the opening width W3 can be set to 25 mm, the distance L2 to 20 to 25 mm, and the width W5 to 40 mm.

(8) As shown in FIG. 10, instead of the bottom parting line 56, the first guide portion 56Fa and the second guide are set with substantially the same radius of curvature of the left and right arcs with the lower end near the spout as the lower end. A bottom dividing line 56F having a portion 56Fb can be provided. In this case, the horn portion 36 can be formed cleanly, and therefore, it is possible to prevent waist breakage and dripping.

(9) As shown in FIG. 10, a liquid leakage restricting portion formed by welding the front surface portion 21 and the rear surface portion 22 in the middle in the height direction of the communication passage 52 and in the middle in the width direction of the communication passage 52 66 can be provided in an island shape. That is, as described above, when the configuration for promoting the movement of the content C from the communication passage 52 to the measuring chamber 51 is adopted, the content C in the storage chamber 50 is filled into the measuring chamber 51 with a smaller force. The content C filled in the measuring chamber 51 is likely to leak from the measuring chamber 51 to the storage chamber 50 when the measuring pouch 1 is vertically oriented. Therefore, by providing the liquid leakage restriction unit 66 at an appropriate position, it is possible to prevent the liquid from leaking from the measuring chamber 51 to the storage chamber 50 while promoting the movement of the contents C to the measuring chamber 51.

  The liquid leakage restricting portion 66 can be formed into any shape, for example, oval, oval annular, rounded rectangular, oval such as oval, oval, annular, horseshoe or the like. In the case of an oval shape, the long axis is disposed along the length direction of the communication passage 52 so as not to inhibit the movement of the content C from the storage chamber 50 to the measurement chamber 51 during measurement. It is preferable to construct as follows. In addition, the size of the liquid leakage restriction unit 66 can be set to any size within the range that does not impede the movement of the content C from the storage chamber 50 to the measuring chamber 51, but, for example, When the width W5 between the upper end P2 and the right inner edge of the main body 20 is set to 40 mm, and the elliptical liquid leakage restriction portion 66 is used, the length of the major axis is set to 10 mm to 12 mm, and the minor axis The length of about 6 mm can be adopted.

  The liquid leakage restriction unit 66 can be formed in the area A1 shown in FIG. Specifically, a curve L3 parallel to the second side edge of the side section line 57F with a constant distance W6, and a vertical direction passing an intersection point P5 between the curve L3 and the outer edge of the tongue portion 36 It can form in the arbitrary positions of field A1 surrounded by line segment L4 and horizontal line segment L5 which passes along the central part of distance L2. The distance W6 can be set to 30% to 70% of the opening width W3. For example, when the opening width W3 is set to 25 mm, the distance W6 is set to 15 mm.

  However, it is preferable to form the liquid leakage restriction portion 66 in an island shape to accelerate the movement of the content C from the storage chamber 50 to the measurement chamber 51 as much as possible. It can also be formed to be continuous with at least one. Specifically, as shown in FIG. 11, a region A2 partitioned by a horizontal line segment L5 and a vertical line segment L6 passing the left end thereof, and a horizontal line segment L7 passing through the upper end P2 And a connection portion 67 formed by welding the front surface portion 21 and the rear surface portion 22 in at least one of the area A3 divided by the line segment L5 and the line segment L4 in all or part of the areas A2 and A3. It can also be provided in line with 66.

(10) As in the case of the side dividing lines 57F shown in FIG. In this case, it is possible to effectively prevent bag breakage from the upper end of the side dividing line 57F when the measuring pouch 1 is dropped. The bag breakage preventing portion 68 can also be provided at the upper end portion of the side dividing lines 57, 57D other than the side dividing line 57F.

(11) As shown in FIG. 10, providing a pouring assist seal 69 formed by welding the front surface portion 21 and the rear surface portion 22 with the line segment L8 connecting the lower end portion of the spout 10 and the bottom portion dividing line 56 as the inner edge. You can also. In this case, the entire content C filled in the measuring chamber 51 can be poured out without tilting the measuring pouch 1 largely.

  The configurations of the other embodiments described in the above (1) to (11) can be provided to the measuring pouch 1 of the above embodiment individually or in any combination.

Next, the evaluation test regarding the laminated film which comprises the main-body part 20 is demonstrated.
As a laminated film, as shown in Table 1, lamination of a three-layer structure of polyethylene terephthalate film (PET), linear low density polyethylene film (LL), and nylon film (NY) in which the film thickness of each layer is set A film was used. And the pouch examples 1 and 2 of the configuration as shown in FIGS. 1 to 6 configured as shown in FIG. 1 to FIG. 6 configured so that the prescribed amount of the storage chamber is 400 cc and the full filling amount of the measuring chamber is 30 cc; A pouch comparative example shown in 6 (a) was manufactured.

  Then, 400 cc of water was filled in the storage chambers of these four types of test pouches 1 to 4, 30 cc of water in the storage chamber was filled in the measuring chamber, and the presence or absence of waist breakage was visually observed.

  As a result, in the pouch comparative example, waist breakage occurred, and in the pouch example 1, the waist breakage was less likely to occur than the pouch comparative example, but when the content of the storage chamber was reduced, the waist breakage became more likely to occur . On the other hand, in the pouch example 2, the horns 35 and 36 were formed cleanly, and the waist was able to be effectively prevented.

  As mentioned above, although embodiment of this invention was described, this invention is not limited at all to embodiment mentioned above, Of course in the range which does not deviate from the summary of this invention, the structure can be changed.
