One embodiment of the present invention will be described with reference to FIGS. 1 to 11C. In addition, in the drawings attached to this specification, for convenience of illustration and easy understanding, the scale, the ratio of length and width, etc. are appropriately changed and exaggerated from those of the real thing.

In addition, the terms such as "parallel", "perpendicular", "same" and the like, length and angle values, etc. that specify shapes and geometric conditions and their degrees used in this specification are strictly It shall be interpreted to include the extent to which similar functions can be expected without being bound by the meaning.

FIG. 1 is a front view showing the pouch 10 viewed from the first surface 1 side. FIG. 1B is a rear view of the pouch 10 viewed from the side of the second surface 2 opposite to the first surface 1. FIG. 1A and 1B show the pouch 10 in a state before being filled with contents, that is, in a state in which no contents are contained therein. In the present embodiment, the concept of a pouch includes not only a pouch in which no contents are contained, but also a pouch in which contents are contained.

The pouch 10 has a container 8 for containing contents. The storage part 8 is a space positioned between the first packaging material forming the first surface 1 and the second packaging material forming the second surface 2 . The container 8 is defined by a first packaging material, a second packaging material and a seal where the first packaging material and the second packaging material are joined. In the front view and rear view of the pouch 10 such as FIGS. 1A and 1B, the plan view of the lidded container described later, and the front view of the tube described later, the seal portion is shaded with oblique lines. As shown in FIG. 1A, when viewed along the normal direction of the first packaging material forming the first surface 1, the accommodating portion 8 is formed inside the sealing portion. In the following description, viewing a package such as a pouch, a container with a lid, or a tube along the normal direction of the first packaging material is simply referred to as a plan view.

It should be noted that the terms "first packaging material" and "second packaging material" described above are merely divisions of each packaging material according to the positional relationship, and the method of providing the packaging material when manufacturing the pouch 10 is , is not limited by the above terms. For example, the pouch 10 may be manufactured using one sheet of packaging material in which the first packaging material and the second packaging material are continuously arranged, or one sheet of the first packaging material and one sheet of the second packaging material. may be manufactured using a total of two packaging materials.

In the following description, a region of the package that overlaps with the housing portion 8 in plan view is referred to as a first region 19 . A region located between the container portion 8 and the outer edge of the package and including the sealing portion that joins the first packaging material and the second packaging material is referred to as a second region 20 .

The contents accommodated in the container 8 of the package such as a pouch, a container with a lid, and a tube are not particularly limited. The containing portion 8 of the package can contain various forms of contents such as liquid, powder, granules, and solids. The contents may be food or non-food.

<Pouch shape>
The shape of the pouch 10 will be explained. In the example shown in FIGS. 1A and 1B, the perimeter of pouch 10 is square. The concept of a quadrilateral includes not only a shape having corners at each corner, but also a shape in which each corner is chamfered to form an outwardly convex arc or curve.

The outer edges of the pouch include a first edge 11, a second edge 12 facing the first edge 11 in the first direction D1, and third and fourth edges 13 and 12 extending between the first edge 11 and the second edge 12. 14 and . The third edge 13 and the fourth edge 14 may face each other in a second direction D2 orthogonal to the first direction D1. The first edge 11 may be positioned on the upper side when the pouch 10 is hung. In this case, the first direction D1 is the vertical direction and the second direction D2 is the horizontal direction.

Reference L1 represents the distance between the first edge 11 and the second edge 12 in the second direction D2. Reference L2 represents the distance between the third edge 13 and the fourth edge 14 in the first direction D1. Distance L1 may be smaller than distance L2. For example, the outline of the pouch 10 may be rectangular with short sides consisting of a first edge 11 and a second edge 12 and long sides consisting of a third edge 13 and a fourth edge 14 . The ratio of the distance L1 to the distance L2 is, for example, less than 1, and may be 9/10 or less, 8/10 or less, or 7/10 or less. The ratio of the distance L1 to the distance L2 is, for example, 1/10 or more, may be 2/10 or more, or may be 3/10 or more. Although not shown, the distance L1 may be longer than or equal to the distance L2. Although not shown, the outer corners of the pouch 10 may be curved. A corner is a portion where two edges are connected.

As shown in FIG. 1A, the first edge 11 is divided into a first portion 11A, a second portion 11B and a third portion 11C arranged from the third edge 13 to the fourth edge 14. As shown in FIG. The length of the first portion 11A, the length of the second portion 11B, and the length of the third portion 11C in the second direction D2 are equal. The second portion 11B is positioned at the center of the first edge 11 in the second direction D2.

<Seal part>
The seal portion will be explained. The seals in the second region 20 of the pouch 10 shown in FIGS. 1A and 1B include a first edge seal 21 extending along the first edge 11, a third edge seal 23 extending along the third edge 13, and A fourth edge seal portion 24 extending along the fourth edge 14 is included. The first edge seal portion 21, the third edge seal portion 23, and the fourth edge seal portion 24 may or may not be in contact with the outer edge of the pouch 10 in plan view. In FIGS. 1A and 1B, the part below the dashed-dotted line at the bottom of the pouch 10 is a second edge-sealing portion 22b which is to become the second edge-sealing portion 22. As shown in FIG.

<Easy-to-open means>
The sealed portion of the pouch 10 may be provided with an easy-to-open means 15 for tearing the packaging material forming the pouch to open the pouch 10 . For example, as shown in FIGS. 1A and 1B, the easy opening means 15 may include a notch 15a extending from the third edge 13 in the second direction D2 and penetrating the third edge seal portion 23. As shown in FIG. The easy-open means 15 may include a half-cut line formed in the third edge seal portion 23 by laser processing, a cutter, or the like. An easy-to-open means 15 may be formed on the fourth edge 14 side.

The easy opening means 15 may be closer to the first edge 11 than to the second edge 12 . For example, as shown in FIG. 1A, the distance L21 between the easy open means 15 and the first edge 11 in the first direction D1 is the distance between the easy open means 15 and the second edge 12 in the first direction D1. may be smaller than the distance L22.

<Hole and Communicating Portion>
The pouch 10 is located in the second region 20 and comprises an aperture 4 extending through the first and second packaging materials. In the example shown in FIGS. 1A and 1B, hole 4 is located in second region 20 between first edge 11 of pouch 10 and container 8 . The hole 4 is a portion for inserting a supporting portion of a hanging tool, which will be described later. In the example shown in Figures 1A and 1B, the contour of the hole 4 is circular.

When the pouch 10 is hung from the hanging tool through the hole 4 , the pouch 10 assumes a posture in which the center of gravity of the pouch 10 is positioned below the hole 4 . In FIG. 1A, a barycenter line connecting the center of the hole 4 and the barycenter of the pouch 10 is denoted by Lg. In the following description, the direction in which the center-of-gravity line Lg extends is also referred to as the center-of-gravity direction. In this embodiment, a case where the first direction D1 is parallel to the direction of the center of gravity will be described. For example, as shown in FIG. 1A, the first direction D1 can be parallel to the direction of the center of gravity when the hole 4 is located in the center of the pouch 10 in the second direction D2.

The pouch 10 has a communication portion 5 extending from the hole 4 to the outer edge of the pouch 10 and penetrating through the first and second packaging materials. In the example shown in FIGS. 1A and 1B, the communication portion 5 extends from the hole 4 to the first edge 11 . The communication portion 5 allows a support portion of a hanging tool, which will be described later, to pass from the first edge 11 side to the hole 4 side. In other words, the communicating portion 5 can connect the first edge 11 and the hole 4 .

The communicating portion 5 may be connected to the second portion 11B of the first edge 11, as shown in FIG. 1A. The hole 4 may overlap the second portion 11B when viewed along the first direction D1. That is, the hole 4 may be arranged close to the center of the first edge 11 . The hole 4 does not have to overlap the first portion 11A and the third portion 11C when viewed along the first direction D1.

As shown in FIG. 1A, the number of holes 4 located in the second region 20 between the first edge 11 and the receiving portion 8 may be one. Although not shown, more than one hole 4 may be located in the second region 20 between the first edge 11 and the receptacle 8 .

FIG. 2A is a front view showing an enlarged area surrounded by a chain double-dashed line labeled A in FIG. 1A. As shown in FIG. 2A, the communicating portion 5 is connected to the hole 4 at a position away from the close position 4c of the hole 4 in the direction orthogonal to the direction of the center of gravity, that is, in the second direction D2. In the example shown in FIG. 2A, the communication portion 5 is located on the right side with respect to the proximity position 4c, that is, on the fourth edge 14 side. The close position 4c is a portion of the contour of the hole 4 where the distance between the outer edge of the pouch 10 in the direction of the center of gravity is the shortest. In the present embodiment, the close position 4c is a portion of the contour of the hole 4 where the distance to the first edge 11 in the first direction D1 is the shortest.

The contour of the hole 4 may include a curved portion, and the curved portion may include the proximal position 4c. In this case, when a hanging tool such as a support portion 71 to be described later is inserted into the hole 4, the pouch 10 moves due to the weight of the pouch 10 to a position where the hanging tool contacts the adjacent position 4c. . Since the proximate position 4c is positioned above the rest of the contour of the hole 4, the pouch 10 is stable at that position. If the hole 4 has a circular contour, the proximal position 4c is at the center of the hole 4 in the second direction D2.

Since the communication part 5 is connected to the hole 4 at a position away from the proximity position 4c, it is possible to prevent the hanging tool inserted in the hole 4 from passing through the communication part 5 due to the weight of the pouch 10. . In the example shown in FIG. 2A, the communicating portion 5 is connected to the hole 4 at the position where the distance from the adjacent position 4c in the second direction D2 is maximized.

As shown in FIG. 2, the contour of the communicating portion 5 from the hole 4 to the outer edge of the pouch 10 includes a first line 5x and a second line 5y. The first line 5x is located on the side of the proximity position 4c with respect to the second line 5y.

As shown in FIG. 2A, the first line 5x and the second line 5y may be partially in contact. That is, the communicating portion 5 may include a portion where the first line 5x and the second line 5y are in contact and a portion where the first line 5x and the second line 5y are not in contact. The portion where the first line 5x and the second line 5y are in contact is obtained by inserting a blade into a portion of the second region 20, for example. Such portions are also referred to as notches 5d. A portion where the first line 5x and the second line 5y are not in contact is obtained by punching out a portion of the second region 20 using, for example, a punching die. Such portions are also referred to as notches 5e.

The notch 5e may be located on the side of the first edge 11 with respect to the notch 5d. For example, the notch 5e may be located at the first edge 11 and the notch 5d may extend from the hole 4 to the notch 5e. The notch 5d may be connected to the hole 4. FIG.

The first line 5x includes a first connection point 5x1. The first connection point 5 x 1 is the position where the first line 5 x is connected to the hole 4 . The first connection point 5x1 may be defined as a position of the first line 5x at which the distance from the first edge 11 in the first direction D1 is maximum. The first line 5 x may extend linearly from the first connection point 5 x 1 toward the first edge 11 .

In the first direction D1, the distance from the first connection point 5x1 to the first edge 11 is greater than the distance from the proximity position 4c to the first edge 11. As shown in FIG. In other words, the first connection point 5x1 is located on the side of the second edge 12 with respect to the proximity position 4c of the hole 4. As shown in FIG. In this case, the contour of the hole 4 located between the close position 4c and the first connection point 5x1 includes a portion displaced toward the second edge 12 toward the first connection point 5x1.

One of the reasons why the pouch 10 suspended by the hanging tool may fall is that the part of the second region 20 in contact with the hanging tool is twisted and the hanging tool passes through the communicating part 5. In the present embodiment, it is considered that the larger the area of the claw portion 20x shaded with oblique lines in FIG. The claw portion 20x is positioned between the first edge 11 and the hole 4 in the first direction D1 in the second region 20, and is positioned between the proximity position 4c and the first line 5x in the second direction D2. This is the part to do.

2A and 2B, reference A1 represents the dimension of the hole 4 in the first direction D1. Reference A2 represents the distance in the first direction D1 between the proximity position 4c and the first connection point 5x1. Reference A3 represents the distance between the proximity position 4c and the first edge 11 in the first direction D1. Reference B1 represents the dimension of the hole 4 in the first direction D1. Reference B2 represents the distance in the second direction D2 between the proximity position 4c and the first connection point 5x1. As the distance A2, the distance A3, and the distance B2 are larger, the area of the claw portion 20x is increased, and the twisting of the claw portion 20x is less likely to occur.

The distance A2 is set so that the claw portion 20x can be stably hooked to the support portion of the suspension. When the support portion of the suspension is a rod-shaped member having rigidity, the distance A2 is, for example, 2 mm or more, may be 3 mm or more, or may be 4 mm or more. If the support portion of the suspension is a member with low rigidity such as a string, rope, string, etc., the distance A2 may be less than 2 mm.

The distance A3 is, for example, 2 mm or more, may be 3 mm or more, or may be 4 mm or more.

Similarly to the distance A2, the distance B2 is also set so that the claw portion 20x is stably hooked to the support portion of the hanging member. When the supporting portion of the hanging tool is a rod-shaped member having rigidity, the distance B2 is, for example, 2 mm or more, may be 3 mm or more, or may be 4 mm or more. The distance B2 may be less than 2 mm when the supporting portion of the suspension is a member with low rigidity such as a string, rope, string, or the like.

As shown in FIG. 2A, the first line 5x and the second line 5y may include curved portions 5c. The curved portion 5 c may form the first line 5 x and the second line 5 y at the position where the first line 5 x and the second line 5 y connect to the first edge 11 . The curved portion 5c is curved to be convex toward the first edge 11 side. By providing such a curved portion 5c, it becomes easier for the hanging tool to enter the communicating portion 5. As shown in FIG.

The second line 5y is located on the side opposite to the proximity position 4c with respect to the first line 5x. In this case, in the operation of suspending the pouch 10 on the suspension tool, it is conceivable that the suspension tool enters the communicating portion 5 along the curved portion 5c of the second line 5y. Considering this point, the curvature radius R2 of the curved portion 5c at the position where the second line 5y connects to the first edge 11 is the curvature radius R2 of the curved portion 5c at the position where the first line 5x connects to the first edge 11. It may be larger than the radius R1.

In order to suppress deformation such as twisting in the portion of the second region 20 such as the claw portion 20x, the strength of the constituent elements of the second region 20 may be increased. For example, the second region 20 of the pouch 10 may include reinforcements 21a.

<Reinforcement part>
In the example shown in FIGS. 1A and 1B, two dashed lines extending in the second direction D2 in the upper portion of the pouch 10 indicate the upper end and lower end of the reinforcing portion 21a. The reinforcing portion 21a is located at the first edge seal portion 21 in which the hole 4 is formed. By providing the reinforcing portion 21a, the strength of the pouch 10 at the periphery of the hole 4 and the communicating portion 5 can be increased. As a result, the pouch 10 can be prevented from being deformed, cracked, or the like.

<Intensity of the second region>
Next, preferable mechanical properties of the second region 20 in which the holes 4 are formed will be described.

For example, the average bending stiffness is preferably 15 g·cm ² /cm or more. Also, the initial bending stiffness is preferably 22 g·cm ² /cm or more.

Bending stiffness is a parameter representing the stiffness of a film. A method for measuring bending stiffness will be described below with reference to FIGS. 4 and 5. FIG.

In measuring the bending stiffness, first, a test piece 80 is cut out from a region of the second region 20 that has the same layer structure as the region where the hole 4 is located. The shape of the test piece 80 is a square having a side length M1, as shown in FIG. Length M1 is 10 mm. The direction of the sides of the test piece 80 is set according to the direction of bending stiffness to be measured. For example, when measuring the bending stiffness in the second direction D2, which is the flow direction of the pouch 10 shown in FIG. 1A, the test piece 80 includes sides extending parallel to the second direction D2.

Subsequently, as shown in FIG. 4, a first clamp 86 and a second clamp 87 of the measuring device 85 are used to grip opposite sides of the test strip 80, respectively. When measuring the bending stiffness in the second direction D2, the test piece 80 is gripped so that the side of the test piece 80 extending in the second direction D2 extends from the first clamp 86 to the second clamp 87. A distance M3 between the first clamp 86 and the second clamp 87 is 10 mm.

Subsequently, the first clamp 86 is tilted relative to the second clamp 87 so as to bend the test piece 80 . Based on the bending moment generated in the test piece 80 at this time, the initial bending stiffness and average bending stiffness of the test piece 80 can be calculated. The initial bending stiffness is the bending moment that occurs in the test piece 80 when the test piece 80 is bent from a flat state. The average bending stiffness is the average value of the bending moment generated in the test piece 80 during one step of bending the test piece 80 from a flat state until the curvature of the test piece 80 reaches the set curvature. The set curvature is 2.5/cm. The curvature change rate is 0.1/cm·s.

On the other hand, if the average bending stiffness is too high, the manufacturability and handleability of the pouch 10 will deteriorate. Considering this point, the average bending stiffness of the test piece 80 in the machine direction may be 50 g·cm ² /cm or less, may be 45 g·cm ² /cm or less, or may be 40 g·cm ² /cm or less. It may be less than or equal to 35 g·cm ² /cm or less.

The average bending stiffness of the test piece 80 in the vertical direction perpendicular to the flow direction is preferably 16 g-cm ² /cm or more, may be 18 g-cm ² /cm or more, and may be 20 g-cm ² /cm or more. It may be 22 g·cm ² /cm or more. The average bending stiffness of the test piece 80 in the vertical direction may be 40 g-cm ² /cm or less, 35 g-cm ² /cm or less, or 30 g-cm ² /cm or less. , 25 g·cm ² /cm or less.

The initial bending stiffness of the test piece 80 in the machine direction is preferably 22 g-cm ² /cm or more, may be 25 g-cm ² /cm or more, may be 30 g-cm ² /cm or more, It may be 40 g·cm ² /cm or more. The initial bending stiffness of the test piece 80 in the machine direction may be 70 g·cm ² /cm or less, 60 g·cm ² /cm or less, or 50 g·cm ² /cm or less. , 45 g·cm ² /cm or less.

The initial bending stiffness of the test piece 80 in the vertical direction is preferably 23 g-cm ² /cm or more, may be 25 g-cm ² /cm or more, may be 28 g-cm ² /cm or more, It may be 30 g·cm ² /cm or more. The initial bending stiffness of the test piece 80 in the vertical direction may be 70 g-cm ² /cm or less, 60 g-cm ² /cm or less, or 50 g-cm ² /cm or less. , 40 g·cm ² /cm or less.

As a measuring device for bending stiffness, a pure bending property tester JTC-911BT manufactured by SMT Co., Ltd. can be used. The environment during measurement of bending stiffness is a temperature of 25° C. and a relative humidity of 50%.

According to the present embodiment, by providing the reinforcing portion 21a including the reinforcing member 55 in the second region 20, the bending stiffness of the region of the second region 20 where the hole 4 is located can be increased. As a result, it is possible to prevent the pouch 10 from falling from the hanging tool due to deformation of the peripheral areas of the hole 4 and the communication part 5 .

<Manufacturing method>
Next, a method for manufacturing the pouch 10 will be described. First, as shown in FIG. 6, the first packaging material 30A and the second packaging material 30B are opposed to each other. Also, a reinforcing member 55 is inserted between the first packaging material 30A and the second packaging material 30B to form a laminate. In this state, the laminate is heat-sealed at a predetermined sealing temperature in regions corresponding to the first edge 11, the third edge 13, and the fourth edge 14 to form the first edge seal portion 21 and the third edge seal portion 23. , forming a fourth edge seal portion 24 . A region of the laminate that overlaps with the reinforcing member 55 becomes the above-described reinforcing portion 21a. The first packaging material 30A, the second packaging material 30B, and the reinforcing material 55 may be long raw rolls extending in the second direction D2 in FIG.

Subsequently, the laminate is punched out using a working tool including a die and a blade to form the hole 4 and the communicating portion 5 . Further, the laminate is cut in the first direction D1 at positions where the third edge 13 and the fourth edge 14 are to be formed. As a result, the pouch 10 shown in FIGS. 1A and 1B having the reinforcing portion 21a, the hole 4 and the communicating portion 5 can be obtained.

Subsequently, the container 8 of the pouch 10 is filled with the contents through the opening 9 on the second edge 12 side. After that, on the second edge 12 side, the inner surface of the first packaging material 30A and the inner surface of the second packaging material 30B are heat-sealed at a predetermined sealing temperature to form the second edge seal portion 22 . Thereby, as shown in FIGS. 9A and 9B, the pouch 10 in which the contents are housed and sealed can be obtained.

<How to use>
Next, an example of how to use the pouch 10 will be described. FIG. 4 is a diagram showing how a plurality of pouches 10 are suspended by a suspension tool 70; The hanging tool 70 includes at least a support portion 71 from which the pouch 10 is hung. The support part 71 is a rod, for example, and is inserted into the hole 4 of the pouch 10 .

The suspender 70 may have a holding portion 72 connected to one end of the support portion 71 . The restraining portion 72 is inclined with respect to the support portion 71 so as to be displaced upward with respect to the support portion 71 as it moves away from one end of the support portion 71 . In other words, the holding portion 72 is inclined downward in the longitudinal direction toward the supporting portion 71 . By providing the holding portion 72 , it is possible to prevent the pouch 10 from falling off from one end of the support portion 71 . A reference numeral 74 denotes a boundary portion between the support portion 71 and the holding portion 72 . The support portion 71 and the restraint portion 72 may be configured by one member that is bent at the boundary portion 74 so that the orientation in the longitudinal direction changes.

The suspender 70 may have a fixing portion 73 connected to the other end of the support portion 71 . The fixed portion 73 is a plate-like member having a predetermined thickness. The fixing portion 73 is formed such that the support portion 71 and the restraining portion 72 both face vertically downward toward the boundary portion 74 when the surface thereof is arranged parallel to the vertical direction. good too. Predetermined attachment means are formed on the back surface of the fixing portion 73 in the same manner as in a conventional hanging tool. With this attachment means, the fixing part 73 can be attached to a fixture or display shelf so that the surface of the fixing part 73 is parallel to the vertical direction.

11A to 11C are diagrams showing an example of the work of hanging the pouch 10 on the hanging tool 70. FIG. This work is performed, for example, by an employee of the store that sells the pouches 10 .

The employee first brings the communication part 5 of the pouch 10 into contact with the support part 71 of the hanging tool 70 . According to the present embodiment, the curved portion 5c exists at the position where the first line 5x and the second line 5y connect to the first edge 11. As shown in FIG. As a result, since the distance between the first line 5x and the second line 5y at the position where the communicating portion 5 connects to the first edge 11 is wide, the positioning of the communicating portion 5 of the pouch 10 with respect to the support portion 71 is facilitated. . Further, the support portion 71 can be easily moved into the first portion 5a of the communicating portion 5 along the curved portion 5c.

Subsequently, the employee moves the pouch 10 upward toward the support portion 71 as indicated by the arrow U in FIG. 11B. This allows the support portion 71 to pass through the communication portion 5 and reach the hole 4 . After that, the employee releases the pouch 10 . Due to the weight of the pouch 10, the pouch 10 moves to a position where the support portion 71 contacts the proximal position 4c, as shown in FIG. 11C. Thereby, the support portion 71 can be kept away from the first connection point 5x1 of the communication portion 5 in the first direction D1 and the second direction D2. Therefore, it is possible to prevent the pouch 10 from falling off from the support portion 71 when the consumer or the like touches the pouch 10 lightly.

Further, according to this embodiment, the support portion 71 can be inserted into the hole 4 via the communication portion 5 . Therefore, as indicated by arrows in FIG. 10, a new pouch 10 can be attached to the support section 71 at any desired position while the plurality of pouches 10 are suspended from the support section 71 . Thereby, the order of the pouches 10 suspended on the support part 71 can be easily adjusted compared to the conventional type pouches 10 in which the pouches 10 are attached to the support part 71 from the holding part 72 side. For example, a new pouch 10 can be arranged on the fixed part 73 side with respect to the pouch 10 already suspended on the support part 71 . As a result, for example, it is possible to easily rearrange the pouches 10 such that the pouches 10 with short expiry dates are arranged on the holding portion 72 side.

Next, the operation of removing the pouch 10 from the support portion 71 by the consumer will be described. The consumer first grabs the pouch 10 suspended on the support portion 71 and moves the pouch 10 to a position where the support portion 71 contacts the first connection point 5x1. The consumer then pulls pouch 10 downward. The support part 71 passes through the communication part 5 of the pouch 10 and the pouch 10 is removed from the support part 71 .
The consumer may pull the pouch 10 downward with the support 71 against the proximal position 4c. Even in this case, the pouch 10 can be removed from the support portion 71 by applying a force to the pouch 10 to the extent that the claw portions 20x are twisted.
The consumer may remove the pouch 10 from the support 71 by manually twisting the claws 20x.

According to this embodiment, the consumer can easily remove a desired pouch 10 from the support portion 71 compared to the conventional pouch 10 removed from the holding portion 72 side. This is particularly useful to consumers where individual variations in pouches 10 exist. For example, consider the case where the packaging material 30 of the pouch 10 is transparent so that the consumer can see the contents of the pouch 10 . In this case, the consumer first confirms the state of the contents of the plurality of pouches 10 suspended on the support part 71 . Subsequently, the consumer removes the pouch 10 with the desired contents from the support 71 . In this way, the consumer can easily select the desired pouch 10 and remove it from the support 71 .
In the present embodiment, similarly to the conventional pouch 10, the pouch 10 is attached to the supporting portion 71 from the suppressing portion 72 side, or the pouch 10 attached to the supporting portion 71 is passed through the suppressing portion 72. It is also possible to remove the

Various modifications can be made to the above-described embodiment. Modifications will be described below with reference to the drawings as necessary. In the following description and the drawings used in the following description, the same reference numerals as those used for the corresponding portions in the above-described embodiment are used for the portions that can be configured in the same manner as in the above-described embodiment, Duplicate explanations are omitted. Further, when it is clear that the effects obtained in the above-described embodiment can also be obtained in the modified example, the explanation thereof may be omitted.

(Modified example of communication part)
The radius of curvature of the curved portion 5c of the first line 5x and the second line 5y is arbitrary. For example, as shown in FIG. 12, the curvature radius R2 of the curved portion 5c of the second line 5y may be larger than in the example shown in FIG. 2A. Further, as shown in FIG. 13, the radius of curvature R1 of the curved portion 5c of the first line 5x and the radius of curvature R2 of the curved portion 5c of the second line 5y may be the same.

(Modified example of communication part)
Alternatively, the first line 5x or the second line 5y may not include the curved portion 5c. In other words, the first line 5 x or the second line 5 y may extend straight from the hole 4 to the first edge 11 . FIG. 14 shows an example in which the first line 5x is composed of a straight portion extending linearly from the hole 4 to the first edge 11. As shown in FIG. FIG. 15 shows an example in which the first line 5x and the second line 5y are composed of straight portions extending linearly from the hole 4 to the first edge 11. As shown in FIG. The communicating portion 5 shown in FIG. 15 is configured by a notch 5d.

(Modified example of communication part)
In the embodiment described above, an example in which the first line 5x and the second line 5y of the communicating portion 5 are partially in contact with each other has been shown. That is, an example in which the communication portion 5 includes the cut 5d and the notch is shown. However, the present invention is not limited to this, and as shown in FIG. 16, the first line 5x and the second line 5y may not be in contact with each other over the entire area. That is, the communicating portion 5 may be configured by the notch 5e. In this case, the interval W2 between the first line 5x and the second line 5y at the first connection point 5x1 is preferably 2.0 mm or less. The interval W2 may be 1.5 mm or less, 1.0 mm or less, or 0.5 mm or less.

(Modified example of communication part)
When the communicating portion 5 includes the notch 5e, the distance between the first line 5x and the second line 5y increases from the hole 4 side toward the first edge 11 side. It may include a linear portion extending linearly. In other words, the direction in which the straight portion of the first line 5x extends may be different from the direction in which the straight portion of the second line 5y extends.

(Modified example of hole)
In the above-described embodiment, the outline of the hole 4 is circular, and more specifically, an example of a perfect circle is shown. However, the contour of the hole 4 is not limited to a perfect circle. For example, as shown in FIGS. 18 and 19, the perforations 4 may have an elliptical profile. In this case, the first dimension S1 of the hole 4 may be smaller than the second dimension S2 of the hole 4, as shown in FIG. Alternatively, the first dimension S1 of the hole 4 may be larger than the second dimension S2 of the hole 4, as shown in FIG. The first dimension S1 is the dimension of the hole 4 in the direction in which the center-of-gravity line Lg extends at the close position 4c. The second dimension S2 is the dimension of the hole 4 in the direction orthogonal to the measurement direction of the first dimension S1.

(Modified example of hole)
In the above-described embodiment or modified example, an example in which the outline of the hole 4 is a circle such as a perfect circle or an ellipse is shown. However, it is not limited to this, and the outline of the hole 4 may be polygonal. For example, as shown in FIG. 20, the contour of the hole 4 may be square. In this case, as shown in FIG. 20, the communicating portion 5 may be connected to the corners of the quadrangle forming the outline of the hole 4. A corner is a portion where two sides forming a polygon such as a quadrangle intersect. Alternatively, although not shown, the communicating portion 5 may be connected to the sides of a quadrangle forming the outline of the hole 4 . Also, as shown in FIG. 21, the contour of the hole 4 may be triangular. In this case, as shown in FIG. 21 , the communicating portion 5 may be connected to the corners of the triangle forming the outline of the hole 4 . Alternatively, although not shown, the communicating portion 5 may be connected to the sides of a triangle forming the outline of the hole 4 . If the contour of the hole 4 is polygonal, the corners of the polygon may include curves as shown in FIG.

18 and 19 above, the first dimension of the hole 4 may be smaller than the second dimension of the hole 4, and the first dimension of the hole 4 may be less than the second dimension of the hole 4. The dimension may be larger than the second dimension of hole 4 . Alternatively, the first dimension of the hole 4 and the second dimension of the hole 4 may be the same.

(Modified example of the positional relationship between the hole and the communicating part)
In the above-described embodiment, an example is shown in which the communicating portion 5 is connected to the hole 4 at the position where the distance from the adjacent position 4c in the second direction D2 is maximized. However, it is not limited to this, and as shown in FIG. It may be connected to the hole 4. In this case, the ratio of distance A2 to dimension A1 may be less than 0.5. Also, the ratio of the distance B2 to the dimension B1 may be less than 0.5.

The ratio of distance A2 to dimension A1 may be 0.45 or less, or 0.4 or less. Also, the ratio of the distance A2 to the dimension A1 may be 0.2 or more, or 0.3 or more.

The ratio of distance B2 to dimension B1 may be 0.45 or less, or 0.4 or less. Also, the ratio of the distance B2 to the dimension B1 may be 0.2 or more, or 0.3 or more.

(Modified example of the positional relationship between the hole and the communicating part)
In the embodiment described above, an example was shown in which the first lines 5x and the second lines 5y of the communicating portion 5 include straight portions extending in the first direction D1. However, the present invention is not limited to this, and the first lines 5x and the second lines 5y may include straight portions extending in a direction inclined with respect to the first direction D1. For example, as shown in FIG. 24, the first line 5x and the second line 5y may include straight portions extending away from the adjacent position 4c as they go from the hole 4 side toward the first edge 11 side. Alternatively, as shown in FIG. 25, the first line 5x and the second line 5y may include straight portions extending from the hole 4 side toward the first edge 11 side so as to approach the proximity position 4c.

According to the example shown in FIG. 24, since the area of the claw portion 20x can be increased, it is possible to suppress the twisting of the claw portion 20x. Therefore, it is possible to prevent the pouch 10 from falling off from the support portion 71 . According to the example shown in FIG. 25, the area of the claw portion 20x can be reduced, so that the claw portion 20x is easily twisted. This makes it easier for consumers and employees to remove the pouch 10 from the support portion 71 .

(Modified example of hole)
In the embodiment described above, an example in which the first packaging material 30A and the second packaging material 30B are punched out at the hole 4 is shown. However, it is not limited to this, and as shown in FIG. may be For example, the contour of the hole 4 includes a first contour 4x having one end connected to the first portion 5a, a second contour 4y having one end connected to the second portion 5b, and other than the first contour 4x. The end and the other end of the second contour 4y may not be connected. In this case, as shown in FIG. 26A, the portion 4a of the packaging material overlapping the hole 4 passes through the hole 4 via a connection 4z located between the other end of the first contour 4x and the other end of the second contour 4y. is connected to the second region 20 on the periphery of the In the example shown in FIG. 26A, the connecting portion 4z is positioned at the lower end of the hole 4 in the first direction D1. The connecting portion 4z may be located at a position different from the lower end of the hole 4 in the first direction D1. For example, the connecting portion 4z may be positioned below the center of the hole 4 in the first direction D1.

As shown in FIG. 26B, the connecting portion 4z may be positioned at the end of the hole 4 in the second direction D2. In this case, the connecting portion 4z is preferably located on the side opposite to the first connection point 5x1 with respect to the center of the hole 4 in the second direction D2.

As shown in Figures 26A and 26B, the connecting portion 4z may not include the proximal position 4c. As a result, when the suspension tool such as the support part 71 is inserted into the hole 4, the suspension tool can be prevented from coming into contact with the connecting part 4z.

As shown in FIG. 26C, the connecting portion 4z may include a proximal position 4c. In this case, it is preferable that the dimension S3 of the connecting portion 4z is sufficiently smaller than the second dimension S2 of the hole 4 . As a result, it is possible to prevent the posture of the pouch 10 from becoming unstable when the hanging member such as the support portion 71 is inserted into the hole 4 . The dimension S3 is the distance between the other end of the first contour 4x and the other end of the second contour 4y. The ratio of the dimension S3 to the second dimension S2 is, for example, 5/10 or less, may be 4/10 or less, may be 3/10 or less, or may be 2/10 or less.

FIG. 27 is a diagram showing how the pouch 10 having the hole 4 shown in FIG. In the operation of hanging the pouch 10 on the hanging tool 70 , the portion 4 a of the packaging material overlapping the hole 4 is pushed by the support portion 71 that has passed through the communicating portion 5 and reached the hole 4 . Thereby, as shown in FIG. 27, the support portion 71 can be inserted into the hole 4 .

(Modified example of arrangement of holes and communicating parts)
In the above-described embodiment, the hole 4 is positioned at the center of the first edge seal portion 21 in the second direction D2, and the communication portion 5 extends from the hole 4 to the first edge 11. As shown in FIG. However, as long as the pouch 10 can be hung on the hanging tool 70, the arrangement of the hole 4 and the communicating portion 5 is not particularly limited. For example, as shown in FIG. 28, the hole 4 may be located on the third edge 13 side with respect to the center of the first edge seal portion 21 in the second direction D2.

In the example shown in FIG. 28 as well, the communicating portion 5 is connected to the hole 4 at a position away from the close position 4c of the hole 4 in the direction orthogonal to the direction of the center of gravity. Therefore, it is possible to prevent the hanging tool inserted in the hole 4 from passing through the communicating portion 5 due to the weight of the pouch 10 itself.

(Modified example of arrangement of holes and communicating parts)
As shown in FIG. 29, the first edge 11 of the pouch 10 may include a first side 11a and a second side 11b located on the housing portion 8 side with respect to the first side 11a. In the example shown in FIG. 29, both the first side 11a and the second side 11b extend in the second direction D2.

The first side 11a may be positioned at the center of the first edge 11 in the second direction D2. In this case, one second side 11b is positioned on the third edge 13 side with respect to the first side 11a, and another second side 11b is positioned on the fourth edge 14 side with respect to the first side 11a. may Also, the hole 4 and the communicating portion 5 may be formed in the first edge seal portion 21 located between the first side 11 a of the first edge 11 and the accommodating portion 8 .

(Modified example of reinforcing material)
FIG. 30 is a cross-sectional view showing a modified example of the reinforcing member 55. As shown in FIG. The stiffener 55 may comprise a packaging material including at least a base layer 56 and a sealant layer 57 . For example, as shown in FIG. 30, stiffener 55 may comprise packaging material folded with sealant layer 57 facing outward. The sealant layer 57 of the reinforcing member 55 located on the side of the first packaging material 30A and the first sealant layer 61 of the first packaging material 30A may be integrated by a heat sealing process. Similarly, the sealant layer 57 of the reinforcing material 55 located on the side of the second packaging material 30B and the second sealant layer 62 of the second packaging material 30B may be integrated by a heat sealing process.

In the example shown in FIG. 30, the reinforcing portion 21a includes four pieces of packaging material including a base material layer and a sealant layer. Specifically, the first packaging material 30A, the packaging material for the reinforcing member 55, the packaging material for the reinforcing member 55, and the second packaging material 30B are included in order from the first surface 1 side to the second surface 2 side. Thus, by providing four sheets of packaging material in the reinforcing portion 21a, the strength of the pouch 10 at the peripheries of the hole 4 and the communicating portion 5 can be increased.

The wrapping material of the stiffener 55 may be the same as the first wrapping material 30A or the second wrapping material 30B. That is, the reinforcing member 55 may be formed using the first packaging material 30A or the second packaging material 30B. This makes it possible to efficiently manufacture the pouch 10 having the reinforcing portion 21a.

First, as shown in FIG. 31, the first packaging material 30A and the second packaging material 30B are opposed to each other. A reinforcing member 55 made of the folded packaging material is inserted between the first packaging material 30A and the second packaging material 30B so that the sealant layer faces outward to form a laminate. In this state, the laminate is heat-sealed at a predetermined sealing temperature to form the first edge seal portion 21, the third edge seal portion 23, and the fourth edge seal portion 24. As shown in FIG. Subsequently, the laminate is punched out using a working tool including a die and a blade to form the hole 4 and the communicating portion 5 . Further, the laminate is cut in the first direction D1 at positions where the third edge 13 and the fourth edge 14 are to be formed. Thereby, the pouch 10 having the reinforcing portion 21a, the hole 4 and the communicating portion 5 can be obtained.

30 and 31 show an example in which the reinforcing member 55 is made of a folded packaging material, but the present invention is not limited to this. For example, although not shown, the reinforcing member 55 may be formed by laminating two packaging materials including a base material layer and a sealant layer so that the sealant layer faces outward. Such two sheets of packaging material may be obtained by folding one sheet and then cutting around the fold.

It should be noted that the packaging material that constitutes the reinforcing material 55 shown in FIG. may be provided.

(Modified example of reinforcing part)
In the above-described embodiment, the reinforcing portion 21a extends in the second direction D2 so as to reach the third edge 13 and the fourth edge 14. As shown in FIG. However, as long as the reinforcing portion 21a surrounds the hole 4, the range of the reinforcing portion 21a is not particularly limited. For example, as shown in FIG. 32 , the reinforcing portion 21a does not have to reach the third edge 13 or the fourth edge 14 . In this case, even if the sealing portion where the first packaging material 30A and the second packaging material 30B are joined is positioned between the reinforcing portion 21a and the third edge 13 or the fourth edge 14 in plan view. good.
