Design Registration No. 1130936

  In patent document 1, although the specific structure of a drinking water dispenser is disclosed, the flat shape of a drinking water packaging bag is completely unknown. Therefore, it is not described or even suggested what flat shape can be easily accommodated in the packaging bag accommodating portion of the drinking water dispenser. Moreover, in the drinking water packaging bag of a nonpatent literature 1, the both ends corner part on the opposite side to an on-off valve is cut off, and the inclined edge is formed. When the drinking water packaging bag of Non-Patent Literature 1 is put into the packaging bag housing portion of the drinking water dispenser of Patent Literature 1 with the opening / closing valve side facing downward, the cut-off inclined edge is gripped by hand. It is difficult to grip because there is no part to grip. In addition, since there are triangular edges at both corners on the open / close valve side, the right and left triangular edges are entangled with the left and right side walls of the storage portion, so that the housing operation is difficult.

  There is another difficulty when the drinking water packaging bag of Patent Document 2 is charged and accommodated in the packaging bag housing portion of the drinking water dispenser of Patent Document 1. Since the right and left corners on the opposite side of the opening / closing valve 233 are not fused at all with triangular edges for gripping by hand, the left and right corners are inflated by injecting drinking water. It is impossible to lift the water bag 230 by gripping the corners. Therefore, there is no method other than holding the body of the water bag 230 with both arms. In addition, the left and right corners of the open / close valve side 233 have cut portions 235 and 235. As described above, the left and right corner portions may or may not be cut. In this case, the flat cut portions 235 and 235 are entangled with the left and right side walls of the drinking water dispenser, and it becomes extremely difficult to store and place the water bag 230 in the packaging bag storage portion by a single operation. Since the packaging bag accommodating portion is located at a considerably high position, it is not easy to hold the water bag 230 with both arms and accommodate it in the packaging bag accommodating portion.

  The present invention has been made in view of the above-described conventional problems, and forms a triangular edge portion for gripping by hand on the left and right corners on the side opposite to the opening / closing valve of the drinking water packaging bag, An inclined edge is formed at the left and right corners, the left and right inclined edges are brought into contact with the upper left and right side walls of the drinking water dispenser, and the drinking water packaging bag is slid and accommodated in the packaging bag accommodating portion by its own weight.

The drinking water packaging bag is lifted, the left and right inclined edges of the drinking water packaging bag are brought into contact with the upper edge of the left and right side walls, respectively, and the inclined edge is formed using the own weight of the drinking water packaging bag. Beverage that slides against the upper edge and drops the drinking water packaging bag into the packaging bag housing portion It is a packaging bag.

The 2nd form of this invention is a drinking water packaging bag which mounts the said opening-and-closing valve in the notch part of the control wall provided ahead of the said packaging bag accommodating part, and accommodates the said drinking water packaging bag in the said drinking water dispenser. is there.

  The third form of the present invention is a drinking water packaging bag in which the outlines of the left and right triangular edge portions are fused and formed by a triangular adhesive band, and the triangular edge portions are held flat in a triangular shape.

  According to a fourth aspect of the present invention, an endless annular fusion band is fused and formed along the outline of the drinking water packaging bag without passing through the triangular fusion band on the left and right sides. The drinking water packaging bag is held flat in a sealed manner, and the drinking water is inflated by injecting the drinking water from the opening / closing valve into a cavity formed inside the annular fusion band. It is a water packaging bag.

  A fifth aspect of the present invention is a drinking water packaging bag in which an inclined edge fusion zone is formed along the inclined edge, and the inclined edge fusion zone constitutes a part of the annular fusion zone.

  In the sixth aspect of the present invention, one end side edge fusion zone is formed along one end side edge between the right and left inclined edges on the one end side, and the one end side edge fusion zone is the annular fusion bond. It is the drinking water packaging bag which comprises some belts.

  A seventh aspect of the present invention is a drinking water packaging bag in which the annular fusion band is formed in an octagonal shape or a substantially octagonal shape.

  According to an eighth aspect of the present invention, the length of the one end side edge of the drinking water packaging bag corresponds to the shortest width of the drinking water packaging bag, and the shortest width is 0.39 of an opposing interval between the left and right side walls. It is a drinking water packaging bag set to 2 times-0.90 times.

  In the ninth aspect of the present invention, the inclination angle of the inclined edge is defined by a narrow angle between the inclined edge and an extension line of the one end side edge, and the inclination angle is set in a range of 35 to 68 degrees. It is a water packaging bag.

  According to a tenth aspect of the present invention, the length of the other end side edge of the other end side of the drinking water packaging bag corresponds to the longest width of the drinking water packaging bag, and the longest width is a distance between opposing sides of the side walls. It is a drinking water packaging bag set to 1.2 times to 2.7 times.

  The present invention, as a result of intensive studies on the above-described conventional flat drinking water packaging bag, for easy accommodation of the hand grip portion and the drinking water dispenser in the packaging bag housing portion, results in the opposite side of the opening / closing valve of the drinking water packaging bag. Triangular edges are formed at the left and right corners to be gripped by hand, and inclined edges are formed at the left and right corners on the open / close valve side so that the left and right inclined edges are in contact with the left and right side walls of the drinking water dispenser. Thus, attention is paid to the fact that the drinking water packaging bag is slid and stored in the packaging bag housing portion by its own weight. This will be described in detail below.

  According to the first embodiment of the present invention, an opening / closing valve is attached to the center of one end side of the drinking water packaging bag, the left and right triangular corners on the one end side are eliminated, and the right and left inclined edges are fused and formed, Since the triangular edge is fused and formed at the left and right corners on the other end of the drinking water packaging bag, the beverage is held in a state where the triangular edge is gripped with both hands and the open / close valve side is directed downward. The water packaging bag can be easily lifted. Triangular edges may be fused in the form of a triangle, a triangular band with a hollow inside, or a multi-point fusion inside the triangle. Is applicable. The upper part of the drinking water dispenser is provided with a packaging bag housing portion having left and right side walls, and the left and right inclined edges of the drinking water packaging bag are brought into contact with the upper end edges of the left and right side walls, respectively. Due to the weight of the drinking water in the drinking water packaging bag, the right and left inclined edges slide downward in the center with respect to the upper edge, and the drinking water packaging bag can be naturally dropped and accommodated in the packaging bag accommodating portion. Therefore, if the drinking water packaging bag is lifted and arranged so that the left and right inclined edges come into contact with the left and right upper edges of the left and right side edges, the drinking water packaging bag will slip naturally due to its own weight, and even if it is not a skilled person, Can be easily dropped and accommodated in the packaging bag accommodating portion by a single operation.

  According to the second aspect of the present invention, since the notch portion is formed in the restriction wall provided in front of the packaging bag housing portion, it is opened and closed when the drinking water packaging bag is dropped and accommodated in the packaging bag housing portion. The valve naturally fits into the notch. That is, the main body of the drinking water packaging bag is regulated by the restriction wall in a state where the opening / closing valve protrudes forward from the notch, and the drinking water packaging bag is prevented from sliding forward from the packaging bag housing portion.

  According to the 3rd form of this invention, the outline of the said triangle edge part on either side is fuse | melted by the triangular fusion zone, and the said triangle edge part is hold | maintained at a triangle shape flatly. As described above, various types of fusion can be used for the method of fusing the triangular edge, but if the triangular fusion zone is formed along the outline of the triangular edge, the width of the fusion zone is reduced. By doing so, the fusion area can be reduced, the size of the fusion part of the upper and lower molds can be reduced, and the power required for fusion can be saved.

  According to the fourth aspect of the present invention, the endless annular fusion band is fused along the outline of the drinking water packaging bag without passing through the left and right triangular fusion bands. Since it is formed, by reducing the width of the fusion band, the fusion area can be reduced, the size of the fusion part of the upper and lower molds can be reduced, and the power required for fusion can be saved. Moreover, if the said annular fusion zone is formed in the outer periphery of the outline of a drinking water packaging bag, the area of the cavity part formed inside the said annular fusion zone can be enlarged, and the amount of drinking water injected from the said on-off valve Can be increased.

  According to the fifth aspect of the present invention, an inclined edge fusion zone is formed along the inclined edge, and the inclined edge fusion zone is configured to be a part of the annular fusion zone. Since the inclined edge slides in contact with the upper edge of the side edge of the packaging bag housing portion, it is necessary to have strength that does not break even if it slides. Increasing strength by setting the width of the inclined edge fusion band large Can guarantee. Further, if the inclined edge fusion band is formed at the edge of the outer edge of the contour, the inclined edge fusion band comes into contact with the upper end edge, which can contribute to improving the strength of the drinking water packaging bag.

  According to the sixth aspect of the present invention, the one end side edge fusion band is formed along the one end side edge between the left and right inclined edges on the one end side on the open / close valve side. The dressing zone is configured to be a part of the annular fusion zone. Since one end side edge contacts the bottom plate of the packaging bag housing portion, when the drinking water packaging bag moves in the packaging bag housing portion, it is necessary to have resistance against friction with the bottom plate. Moreover, if the bottom plate is a heating plate or a cooling plate, the one end side edge fusion zone needs to have a certain proof strength against heating or cooling. Therefore, the required yield strength can be guaranteed by adjusting the width of the inclined edge fusion band.

  According to the 7th form of this invention, the said annular fusion zone is formed in octagon shape or substantially octagon shape. In the drinking water packaging bag of the present invention, the right and left corners on the open / close valve side are formed with the inclined edges by removing the triangular parts, and the right and left corners opposite to the open / close valve are formed with the triangular edges. When the annular fusion band is formed along the outline of the drinking water packaging bag, the shape of the annular fusion band becomes an octagonal shape or a substantially octagonal shape. The octagonal shape or substantially octagonal shape has higher symmetry than other shapes, in other words, it is close to a circle. It is desirable that the water pressure acts uniformly on the peripheral surface of the drinking water packaging bag when the drinking water is filled into the drinking water packaging bag, and in the case of an octagonal shape or a substantially octagonal shape, the water pressure is uniform. The durability of the drinking water packaging bag after pouring of drinking water can be improved.

  According to the 8th form of this invention, the length of the said one end side edge of the said drinking water packaging bag is equivalent to the shortest width of the said drinking water packaging bag, and the ratio with respect to the opposing space | interval of the said side wall of the said shortest width (Referred to as short ratio in the present invention) is preferably set to 0.39 to 0.90. As the short ratio increases, the surface area of the drinking water packaging bag increases and the amount of drinking water that can be injected increases. On the other hand, when this short ratio increases, the inclination angle of the inclined edge increases, and it becomes difficult to bring the inclined edge into contact with the upper edge of the left and right side walls. As a result, the drinking water packaging bag can be easily accommodated in the packaging bag accommodating portion. Tends to be low. As a result of various experiments, the inventors have clarified that the short ratio is in the range of 0.39 to 0.90 and both the amount of drinking water and the ease of accommodation are well maintained.

  According to the ninth aspect of the present invention, an inclination angle of the inclined edge is defined by a narrow angle between the inclined edge and an extension line of one end side edge, and the inclination angle is set in a range of 35 degrees to 68 degrees. It is desirable. When the inclination angle increases, the surface area of the drinking water packaging bag increases and the amount of drinking water that can be injected increases. On the other hand, when the inclination angle increases, as described above, it becomes difficult to make the inclined edges come into contact with the upper end edges of the left and right side walls, and as a result, the ease of accommodation of the drinking water packaging bag into the packaging bag accommodating portion tends to decrease. Have As a result of various experiments, it has become clear by the present inventors that the inclination angle is in the range of 35 to 68 degrees, and that both the amount of drinking water and the ease of accommodation are well maintained.

  According to the 10th form of this invention, the length of the other end side edge of the said other end side of the said drinking water packaging bag is equivalent to the longest width | variety of the said drinking water packaging bag, and the opposition of the said side wall of the said longest width | variety The ratio to the interval (referred to as a long ratio in the present invention) is preferably set to 1.2 to 2.7. As the length ratio increases, the surface area of the drinking water packaging bag increases and the amount of drinking water that can be injected increases. On the other hand, when the length ratio increases, the inclination angle of the inclined edge decreases, and it becomes difficult for the inclined edge to slide down the upper edge of the left and right side walls and fall to the center. The ease of accommodation tends to be low. As a result of various experiments, the inventors have clarified that the length ratio is in the range of 1.2 to 2.7, and both the amount of drinking water and the ease of accommodation are well maintained.

In the present invention, it is important that the left inclined edge 12 abuts on the upper left edge 44a and the right inclined edge 14 abuts on the upper right edge 46a as a condition for accommodating the drinking water packaging bag 1 in the packaging bag accommodating portion 42. . If this contact is established, the left inclined edge 12 slides down the upper left edge 44a downward due to the weight of the drinking water due to the downward inclination angle θ. Similarly, the right inclined edge 14 slides down the upper right end edge 46a downward due to the weight of the drinking water at the downward inclination angle θ. By this sliding / sliding down, the drinking water packaging bag 1 is naturally placed and placed in the packaging bag housing portion 42.
Since the reference numerals of the drawings have already been described, the description thereof is omitted here.

FIG. 7 is an initial layout diagram for accommodating the drinking water packaging bag according to the present invention into which drinking water is injected in the accommodating portion of the drinking water dispenser. The operator holds the left triangular edge 16 and the right triangular edge 18 with both hands, lifts the drinking water packaging bag 1 so that the opening / closing valve 28 is on the lower side, and packs the drinking water packaging bag 1 into the drinking water dispenser 40. It arrange | positions above a bag accommodating part and drops the drinking water packaging bag 1 in the arrow direction.

  FIG. 8 is an intermediate layout view in which the left and right inclined edges of the drinking water packaging bag are placed in contact with the upper left and right side edges of the storage part of the drinking water dispenser. In order to efficiently store the drinking water packaging bag 1 in the packaging bag accommodating portion 42, the left inclined edge 12 is brought into contact with the left upper end edge 44a, and at the same time, the right inclined edge 14 is brought into contact with the upper right end edge 46a. is important. Further, the opening / closing valve 28 is disposed immediately above the notch 54. In this arrangement, when the hand is pulled out, the drinking water storage bag 1 slides down due to its own weight. More specifically, the left inclined edge 12 falls downward while sliding along the upper left edge 44a, and the right inclined edge 14 falls downward while sliding along the upper right edge 46a. At this time, when the hand is released, the drinking water packaging bag 1 falls into the packaging bag accommodating portion 42 at a stretch, but it is not recommended to release the hand because the impact is great. The recommended procedure is to slowly move the drinking water packaging bag downward while loosening the hand force and place the drinking water packaging bag 1 on the bottom plate 50 while fitting the opening / closing valve 28 to the notch 54. Stabilize. During this time, it is preferable to continue gripping by hand.

  FIG. 9 is a final layout view in which the drinking water packaging bag is accommodated and disposed in the accommodating portion of the drinking water dispenser. In the lifted state, the drinking water packaging bag 1 is shaped as shown in FIG. 7, but in the accommodated state, the drinking water packaging bag 1 is regulated by the outer wall of the packaging bag accommodating portion 42, and thus accommodates in a substantially rectangular parallelepiped shape. Be placed. The on-off valve 28 is fitted into the notch 54 and protrudes outward. In this state, a required amount of drinking water can be supplied to the cup by disposing the cup below the nozzle and opening / closing the open / close lever.

  As described above, in order to efficiently accommodate and place the drinking water packaging bag 1 in the packaging bag accommodating portion 42 of the drinking water dispenser 40, the shortest width SW of the one end side edge 4 is the left and right side walls 44 of the packaging bag accommodating portion 42. , 46 is smaller than the facing distance W, which is an important condition. As another important condition, there is an inclination angle θ. If the inclination angle θ is small, it is difficult to slip, and if it is large, it is slippery. Furthermore, the longest width LW exists as an important condition. When the longest width LW is large, it is difficult to accommodate, and when it is small, it is easy to accommodate. The range setting of the shortest width SW, the inclination angle θ, and the longest width LW will be described in detail below using Tables 1 to 3.

[Invention Test (Table 1): Determination of Range of Short Ratio RS]
Regarding the relative relationship between the shortest width LW and the facing interval W, the short ratio RS of the shortest width SW to the facing interval W is experimentally examined. This short ratio RS is given by RS = SW / W. The experiment was performed under the following preconditions (1) to (5).
(1) The shortest width SW is larger than zero and smaller than the facing interval W.
(2) The longest width LW is fixed to 48.5 cm, and the facing interval W is fixed to 25.5 cm.
(3) The bag height H is fixed at 54.5 cm.

At each stage, drinking water was poured into the drinking water packaging bag 1 until it was 85% full, and was actually stored in the packaging bag storage portion 42 of the drinking water dispenser 40 to determine the ease of accommodation. . Moreover, since the amount of drinking water that can be injected increases as the packaging bag area S increases, the amount of drinking water is determined by the size of the packaging bag area S. The determination of the amount of drinking water and the ease of accommodation is four stages. The comprehensive determination is a result of comprehensive determination using both the amount of drinking water and the ease of accommodation. In the same way as described above, the overall judgment was evaluated in four stages: double circle, circle, acceptable, and impossible. Finally, the range of the short ratio RS was determined using double circles, circles, and good for comprehensive judgment.

  Regarding the amount of drinking water, the packaging bag area S was 2400 cm 2 or more, double circles, 2240 cm 2 or more circles, 2100 cm 2 or more triangle cities, and less than 2100 cm 2 x. The ease of accommodation was judged by looking at the actual sliding state of the drinking water packaging bag. The shortest width SW was 17.5 cm or less, a double circle, 20.0 cm or less, a circle, 23.0 cm or less, a triangle. As a result, in the comprehensive determination, the range of the short ratio surrounded by the triangle is 0.39 ≦ RS ≦ 0.90, and if this short ratio is within the range, the drinking water packaging bag 1 can be efficiently packed in the packaging bag housing portion. 42 was found to be able to be accommodated in 42.

[Invention test (Table 2): Determination of the range of the inclination angle θ]
Regarding the correlation between the inclination angle θ and the ease of accommodation, in general, the ease of accommodation becomes worse when the inclination angle θ is small, and the ease of accommodation is improved when the inclination angle θ is large. The experiment for determining the range of the inclination angle θ is based on the best conditions in Table 1, that is, the shortest width SW = 17.5 cm, the longest width LW = 48.5 cm, the facing interval W = 25.5 cm, and the short ratio RS = 0.69. The following conditions (1) to (5) were performed.
(1) The experiment is performed with the inclination angle θ in the range of 30 to 74 degrees. The reason is that the maximum inclination angle θmax = 74.1 degrees given by the following equation under the best conditions.
θmax = tan−1 [H / {(LW−SW) / 2}] = 74.1 degrees (2) longest width (LW = 48.5 cm)> facing distance (W = 25.5 cm)> shortest width (SW = 17.5 cm).
(3) The bag height H is fixed at 54.5 cm.
(4) Short ratio RS = SW / W = 0.69
(5) The packaging bag area S is calculated by the following formula.
S = LW × H − [(LW−SW) /] ² × tan (θ)
= 2643-240 × tan (θ)

  In Table 2, the shortest width SW = 17.5 cm, the longest width LW = 48.5 cm, the facing interval W = 25.5 cm, and the bag height H = 54.5 cm. The inclination angle θ was set to the following 11 stages, that is, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 68 degrees, 70 degrees, and 74 degrees. At each stage, drinking water was poured into the drinking water packaging bag 1 until it was 85% full, and was actually stored in the packaging bag storage portion 42 of the drinking water dispenser 40 to determine the ease of accommodation. . Moreover, since the amount of drinking water that can be injected increases as the packaging bag area S increases, the amount of drinking water is determined by the size of the packaging bag area S. The determination of the amount of drinking water and the ease of accommodation is four stages, the double circle is excellent, the circle is a single circle, the circle is acceptable, the triangle is unusable, and the circle is not allowed. The comprehensive determination is a result of comprehensive determination using both the amount of drinking water and the ease of accommodation.
