First, we will explain the whole picture of using the crust structure. The bag-shaped container is formed of a soft sheet material (soft packaging film). A soft sheet material shows little rigidity in compression and bending. Therefore, in the bag-shaped container of the prior art, once the column standing at the center of the container starts to tilt once by force, the surrounding membrane is subjected to a compressive force or a bending force, so that it cannot be supported and tilts (falls down). . For this reason, it has not been practical to use the conventional bag-shaped container like a bottle without refilling. However, the films exhibit very high stresses against tensile forces. The clam structure is a method of obtaining rigidity by using the tension of the membrane. The present invention has noted this.

If the bending or compressive force acting on the bag-like container from outside can be converted into tension by some mechanism, the bag-like container is sufficiently squeezed by the tension generated in the film of the bag-like container. Can be independent. By devising a mechanism for converting bending or compressive force into tension, the present invention can be implemented. That is, changing the bending or compression force into tension means an operation of changing the direction of the force vector. There are many mechanisms to change the direction of the force. In the present invention, the simplest balance mechanism was used. The balance operates on the principle of leverage with the fulcrum centered on the balance bar (arm). The lever principle refers to two functions. One is to convert the magnitude of the force according to the distance from the fulcrum. The other is the action of changing the direction of the force.

For example, when focusing on the point of force and the point of action, the directions of the forces are always opposite. The phenomenon that one of the seesaws goes down and the other goes up is due to the reversal of this force. In addition, the force acting on the fulcrum is distributed half to both ends of the arm, and the direction of the force at both ends is always opposite to the fulcrum when suspended. It is the result of changing the direction of the force that the work on the tip of the arm pulls out when the center bolt of the gear puller is tightened.

In the present invention, utilizing the function of the balance (lever) to change the direction of the force, the bending or compressing force that the film is not good at is changed into the tension that the film is good at. Establishing a crust structure using this mechanism makes it possible to realize a very robust container close to a thick bottle, even though it is a bag-shaped container formed of a soft sheet material.

Hereinafter, in a specific embodiment, where the balance mechanism is formed and how the external force is converted into tension. Further, it will be described step by step which part of the bag-shaped container supports the tension. <First Embodiment> An example of a bag-like container and a container unit according to a first embodiment of the present invention will be described with reference to FIGS. In addition, arrow H shown in the figure indicates the container vertical direction (vertical direction), arrow W indicates the container width direction (horizontal direction), and arrow D indicates the container front-rear direction (horizontal direction).

Further, as shown in FIGS. 2 and 3, the bag body 30 has a hexagonal cross section cut in a direction orthogonal to the vertical direction (longitudinal direction) (see FIG. 4). The bag body 30 includes a front material 32 and a rear material 34 as side portions of the bag body 30, a top material 36 as a top portion of the bag body 30, and a bottom material 38 (bottom portion) as a gusset of the bag body 30. Example).

As shown in FIG. 4, the front member 32 extends in the up-down direction, and has front and rear surfaces 32 b with the seat surface facing the front and rear direction, and is disposed on both sides in the container width direction with respect to the front and rear surface 32 b and the sheet is provided. And a pair of inclined surfaces 32c whose surfaces are inclined with respect to the front-rear direction. The front and rear surfaces 32b are an example of opposing surfaces. Further, a pair of bent portions 32a that are separated in the container width direction are formed between the one inclined surface 32c and the front and rear surface 32b and between the other inclined surface 32c and the front and rear surface 32b. .

The rear member 34 is symmetrical to the front member 32 with respect to a plane (S1 in FIG. 4) passing through the center of the bag body 30 and orthogonal to the container front-rear direction. The rear member 34 has a pair of bent portions 34a, front and rear surfaces 34b, and a pair of inclined surfaces 34c. The front and rear surfaces 34b of the rear member 34 face the front and rear surfaces 32b of the front member 32 in the horizontal direction. The front and rear surfaces 34b are an example of opposing surfaces. The widthwise ends of the rear member 34 and the widthwise ends of the front member 32 overlap and are welded.

As shown in FIG. 4, the top material 36 constitutes a top portion (ceiling) of the bag body 30. Further, a circular opening 36a (see FIG. 3) is formed at the center of the ceiling material 36. The outer peripheral portion of the top member 36 is bent upward, and the bent portion and the upper end portions of the front member 32 and the rear member 34 are overlapped and welded.

The bottom member 38 forms the bottom of the bag body 30 as shown in FIG. The outer peripheral portion of the bottom member 38 is bent downward, and the bent portion and the lower end portions of the front member 32 and the rear member 34 overlap and are welded.

And a plate-like support portion 44 whose surface faces in the vertical direction.

An external thread is formed on the outer peripheral surface of the cylindrical portion 42. The support portion 44 is disposed inside the bag body 30 and has a rectangular shape when viewed from above. The support portion 44 is provided along the front and rear surfaces 32b of the front member 32 when viewed from above. An edge 44a formed along the front and rear surfaces 34b of the rear member 34 is formed. The support portion 44 is fixed to the back surface of the top material 36 of the bag body 30 (the surface facing the inside of the bag body 30) using a fixing material (not shown).

In this configuration, when a downward moving force acts on the lower end portion of the front and rear surface 32b of the front member 32, the support portion 44 of the spout 40 supports the upper end portion of the front and rear surface 32b of the front member 32. As a result, a force that increases the vertical distance between the lower end portion and the upper end portion of the front and rear surface 32b acts on the front and rear surface 32b of the front member 32. Further, when a downward moving force acts on the lower end portion of the front and rear surface 34 b of the rear member 34, the support portion 44 of the spout 40 supports the upper end portion of the front and rear surface 34 b of the rear member 34. As a result, a force for increasing the vertical distance between the lower end portion and the upper end portion of the front and rear surface 34b acts on the front and rear surface 34b of the rear member 34.

[Band 50] The band 50 is formed using a soft sheet material. As shown in FIGS. 3 and 4, the band 50 has a U-shape when viewed from the container width direction, and has a pair of side portions 50a and a bottom portion connecting the lower ends of the pair of side portions 50a. 50b.

Further, as shown in FIG. 5B, one side portion 50a is overlapped and welded to the lower end portion of the front and rear surfaces 32b of the front member 32. Further, the other side portion 50a overlaps and is welded to the lower end portion of the front and rear surfaces 34b of the rear member 34. Further, the bottom 50b of the band 50 is vertically separated from the bottom 38 of the bag body 30. In other words, the band body 50 is provided across the outer peripheral portion of the bottom member 38. A space in which the pedestal 56 is arranged (inserted) is formed between the bottom portion 50b of the band 50 and the bottom member 38 of the bag body 30.

[Pedestal 56] The pedestal 56 is a plate-shaped rigid body. As shown in FIGS. 2 and 3, the pedestal 56 has a rectangular shape when viewed from above. The pedestal 56 has an edge 56a along the front and rear surface 32b of the front member 32 when viewed from below. And an edge 56b along the front and rear surfaces 34b of the rear member 34. 5A and 5B, the pedestal 56 is sandwiched between the bottom portion 50b of the band body 50 and the bottom member 38 of the bag body 30, and is detachable from the bag-like container 20. It has been. The pedestal 56 can be reused any number of times by detaching it from the bag-shaped container 20.

In this configuration, when the pedestal 56 is attached to the bag-shaped container 20, the center line (the center line C1 in FIGS. 6 and 7) extending in the vertical direction of the bag-shaped container 20 is aligned with the center of the pedestal 56 (as viewed from above). (The point where the diagonal lines of the pedestal 56 intersect). Further, when a force for moving the pedestal 56 downward acts on the pedestal 56, the force is transmitted to the lower end portions of the front and rear surfaces 32 b of the front member 32 and the lower end portions of the front and rear surfaces 34 b of the rear member 34 via the strip 50. Is done. Then, a force to move the lower end of the front and rear surfaces 32b of the front member 32 and the lower end of the front and rear surfaces 34b of the rear member 34 acts.

[Pump 60] The pump 60 is a member that discharges the liquid inside the bag body 30 to the outside by a fixed volume, and is detachable from the bag-shaped container 20. As shown in FIGS. 1 and 3, the pump 60 includes a columnar vertical member 78 extending vertically and a piston 64 movable vertically with respect to the vertical member 78. A disk-shaped end portion 66 fixed to the upper end of the longitudinal member 78 is provided. Further, the pump 60 passes below the end portion 66 through a cap portion 68 movable in the circumferential direction of the longitudinal member 78 with respect to the end portion 66 and the longitudinal member 78, and a pipe 70 described later. And a discharge nozzle 72 from which the liquid is discharged. The cap portion 68 is formed in a cylindrical shape, and on the inner peripheral surface of the cap portion 68, a female screw that meshes with a male screw formed on the outer peripheral surface of the cylindrical portion 42 (see FIG. 3) of the spout 40 is formed.

The longitudinal member 78 has a main body 62 to which the end 66 is fixed, a pipe 70 extending below the lower end of the main body 62, and a part of the pipe 70 inserted below the main body 62. And a moving unit 74 that can move up and down with respect to the main body 62.

In this configuration, as shown in FIGS. 6 and 7, the longitudinal member 78 of the pump 60 is inserted from the cylindrical portion 42 of the spout 40 into the bag body 30, and the cap portion 68 of the pump 60 is connected to the cylindrical portion of the spout 40. The pump 60 is mounted on the bag-like container 20 by being screwed into the portion 42. With the pump 60 mounted on the bag-shaped container 20, the center line C1 extending in the vertical direction of the bag-shaped container 20 and the center line extending in the vertical direction of the longitudinal member 78 overlap. Further, the pump 60 (vertical member 78) can be tilted with respect to the pedestal 56 with the lower end of the vertical member 78 as a fulcrum (see FIGS. 8 and 9).

The pump 60 can be reused any number of times by detaching it from the bag-shaped container 20.

[Biasing Member 80] The biasing member 80 is a band-shaped leaf spring disposed before and after the longitudinal member 78 as shown in FIG. When the urging member 80 is compressed from above and below, as shown in FIG. 7, the urging member 80 bends in an anteroposterior V-shape in an anteroposterior direction.

Specifically, two urging members 80 are arranged vertically in front of the longitudinal member 78, and two urging members 80 are arranged rearward of the longitudinal member 78. They are arranged side by side in the vertical direction. When viewed from the width direction, the urging member 80 disposed on the front side with respect to the longitudinal member 78 and the urging member 80 disposed on the rear side with respect to the longitudinal member 78 are symmetrically disposed. ing.

The upper end 80b of the urging member 80 disposed on the upper side is fixed to the main body 62 of the longitudinal member 78 by a fixing member (not shown), and the lower end 80c of the urging member 80 disposed on the upper side is It is fixed to the upper end 80b of the urging member 80 arranged below by a fixing member (not shown). Further, the lower end 80c of the urging member 80 disposed below is fixed to the moving part 74 of the longitudinal member 78 by a fixing member (not shown).

In other words, the lower end 80c of the urging member 80 arranged on the upper side is fixed to the moving part 74 of the longitudinal member 78 via the urging member 80 arranged on the lower side by a fixing member (not shown). I have. The upper end 80b of the urging member 80 disposed on the lower side is fixed to the main body 62 of the longitudinal member 78 by a fixing member (not shown) via the urging member 80 disposed on the upper side.

Further, when viewed from the container width direction, the bent portion 80a of the urging member 80 projects toward the front and rear surfaces 32b and 34b with respect to the upper end 80b and the lower end 80c of the urging member. The bent portion 80a is an example of an intermediate portion.

Further, a regulating member that regulates the fixed portion where the lower end 80c of the urging member 80 arranged on the upper side and the upper end 80b of the urging member 80 arranged on the lower side are solidified to move in the container front-rear direction. 82 are provided. Specifically, the regulating member 82 is formed in an annular shape, and is provided at a fixed portion of the urging member 80 disposed on the front side with respect to the longitudinal member 78 and on the rear side with respect to the longitudinal member 78. It is arranged so as to surround the fixed portion of the urging member 80 from the outside.

In this configuration, as shown in FIG. 6, a state in which the longitudinal member 78 of the pump 60 is inserted from the cylindrical portion 42 of the spout 40 into the inside of the bag body 30 (a state in which external force is not accumulated in the urging member 80). In the state (the state in which the urging member 80 is not compressed), the main body 62 and the moving unit 74 are vertically separated from each other. Further, in this state, the bending portion 80a of the urging member 80 which extends in a substantially V-shape extends in the up-down direction by its own elasticity, is retracted toward the longitudinal member 78, and the bending portion 80a and the front and rear surfaces of the bag body 30 are formed. 32b and 34b are spaced apart in the container front-rear direction.

On the other hand, as shown in FIG. 7, in a state where the pump 60 is mounted on the bag-shaped container 20, the urging member 80 is elastically deformed, so that the main body 62 and the moving unit 74 come into contact with each other. Specifically, when the urging member 80 is compressed in the vertical direction, the urging member 80 is elastically deformed into a substantially V-shape so that the upper end 80b and the lower end 80c are close to each other in the vertical direction. 80a projects in the front-back direction. Thereby, the bent portion 80a of the biasing member 80 moves to the front and rear surfaces 32b and 34b of the bag body 30, and comes into contact with the front and rear surfaces 32b and 34b.

As described above, the pair of urging members 80 arranged on the front side and the rear side with respect to the longitudinal member 78 move like a pantograph. Further, each biasing member 80 is deformed into an arch shape and functions as a flying beam that supports the front and rear surfaces 32b and 34b from inside the bag body 30.

[Operation] Next, the operation of the bag-shaped container 20 and the container unit 10 will be described. First, a process of attaching the pump 60 and the pedestal 56 to the bag-shaped container 20 to form the container unit 10 will be described.

The pedestal 56 is inserted between the bottom 50b of the band 50 and the bottom member 38 of the bag body 30 from the container width direction, as shown in FIGS. 5A and 5B. Thereby, the pedestal 56 is sandwiched between the bottom 50 b of the band 50 and the bottom member 38 of the bag body 30, and is attached to the bag-like container 20.

As shown in FIG. 6, the longitudinal member 78 of the pump 60 is inserted from the cylindrical portion 42 of the spout 40 into the bag body 30. The urging member 80 passes through the cylindrical portion 42 of the spout 40 by elastically deforming the urging member 80 such that the bent portion 80a of the urging member 80 approaches the longitudinal member 78. In this state, the main body 62 and the moving unit 74 are vertically separated from each other, and the bent portion 80a of the urging member 80 and the front and rear surfaces 32b and 34b of the bag main body 30 are separated from each other in the container front and rear direction. I have.

Further, by tightening the cap portion 68 of the pump 60 to the cylindrical portion 42 of the spout 40, the urging member 80 is elastically deformed as shown in FIG. 7, and the pump 60 is mounted on the bag-like container 20. . Specifically, the urging member 80 is elastically deformed so that the upper end 80b and the lower end 80c of the urging member 80 approach in the vertical direction. As a result, the bent portion 80a of the urging member 80 moves toward the front and rear surfaces 32b and 34b of the bag body 30, and comes into contact with the front and rear surfaces 32b and 34b.

The elastically deforming urging member 80 urges the moving portion 74 toward the pedestal 56 (downward). Thus, a force for moving the spout 40 downward relative to the spout 40 acts on the pedestal 56. The force acting on the pedestal 56 is transmitted to the lower end portion of the front and rear surface 32b of the front member 32 and the lower end portion of the front and rear surface 34b of the rear member 34 via the band 50. Therefore, a force to move the spout 40 relatively downward is applied to the lower end of the front and rear surfaces 32b of the front member 32 and the lower end of the front and rear surfaces 34b of the rear member 34.

On the other hand, the support portion 44 of the spout 40 supports an upper end portion of the front and rear surfaces 32b of the front member 32 and an upper end portion of the front and rear surfaces 34b of the rear member 34. As a result, a force that increases the vertical distance between the lower end portion and the upper end portion of the front and rear surface 32b acts on the front and rear surface 32b of the front member 32. Similarly, a force for increasing the vertical distance between the lower end portion and the upper end portion of the front and rear surface 34b acts on the front and rear surface 34b of the rear member 34.

As a result, a vertical tension (hereinafter, “initial tension”) is generated on the front and rear surfaces 32b of the front member 32 and the front and rear surfaces 34b of the rear member 34. The soft sheet material forming the bag body 30 hardly generates stress (resistance) against bending or compression. However, a soft sheet material generates a tough stress (resistance) against tension. Specifically, it is assumed that the pedestal 56 and the longitudinal member 78 constitute an inverted balance (inverted balance) using the pedestal 56 as a balance rod and the lower end of the longitudinal member 78 as a fulcrum. Then, the initial tension of the front and rear surfaces 32b acting on one end of the pedestal 56 and the initial tension of the front and rear surfaces 34b acting on the other end of the pedestal 56 are balanced with the lower end of the longitudinal member 78 as a fulcrum. .

Here, the soft sheet material forming the bag body 30 hardly generates stress (resistance) against bending or compression. However, a soft sheet material generates stress (resistance) against tension. In other words, when tension is generated in the soft sheet material, the bending rigidity of the sheet material is improved, and the posture of the sheet material is stabilized.

In the present embodiment, as described above, the vertical tension is generated on the front and rear surfaces 32b of the front member 32, and the vertical tension is generated on the front and rear surfaces 34b of the rear member 34. Further, the tension generated on the front and rear surfaces 32b and the tension generated on the front and rear surfaces 34b are balanced with the lower end of the moving unit 74 as a fulcrum. Accordingly, the rigidity of the bag-shaped container 20 against bending and compression is improved, and the posture of the bag-shaped container 20 is stabilized.

As described above, a structure for improving rigidity against bending and compression of the bag-shaped container 20 by generating initial tension in the vertical direction on the front and rear surfaces 32b of the front member 32 and the front and rear surfaces 34b of the rear member 34 is described as a crust. Called structure.

Next, a case where an external force acting on the container unit 10 to tilt the container unit 10 (to tilt the container unit 10 so as to collapse the force acting on the container in the left, right, front and rear directions) will be described.

As shown in FIG. 8, when an external force that inclines the container unit 10 is applied to the container unit 10 so that the tip of the container unit 10 moves rearward when viewed from the container width direction, the longitudinal member 78 becomes vertical. With the lower end of the passing member 78 as a fulcrum, it is tilted rearward. Then, when the longitudinal member 78 is inclined rearward with the lower end of the longitudinal member 78 as a fulcrum (when the inverted balance formed by the longitudinal member 78 and the pedestal 56 is inclined backward), the edge 44 a of the support portion 44 of the spout 40. The distance (distance L1 in the figure) between the pedestal 56 and the edge 56a of the pedestal 56 is widened (the inverted balance automatically instructs to apply tension to the lateral membrane at the most appropriate position for suppressing the tilt). Thereby, the tension generated on the front and rear surfaces 32b of the front member 32 becomes stronger than the initial tension, and the tilting of the container unit 10 is suppressed.

When the external force for tilting the container unit 10 is released, the tension of the front and rear surfaces 32b and the tension of the front and rear surfaces 34b are balanced with the lower end of the longitudinal member 78 as a fulcrum, so that the posture of the container unit 10 is: It returns to the initial state shown in FIG.

As shown in FIG. 9, when an external force acting on the container unit 10 to incline the container unit 10 so that the tip of the container unit 10 moves forward when viewed from the container width direction, the longitudinal member 78 becomes The longitudinal member 78 is tilted forward with the lower end as a fulcrum. When the longitudinal member 78 is tilted forward with the lower end of the longitudinal member 78 as a fulcrum (when the inverted balance formed by the longitudinal member 78 and the pedestal 56 is tilted forward), the edge 44 b of the support portion 44 of the spout 40. The distance (distance L2 in the figure) between the pedestal 56 and the edge 56b of the pedestal 56 is widened (the inverted balance automatically instructs to apply tension to the lateral membrane at the most appropriate position for suppressing the inclination). Thereby, the tension generated on the front and rear surfaces 34b of the rear member 34 becomes stronger than the initial tension, and the tilting of the container unit 10 is suppressed.

When the external force for tilting the container unit 10 is released, the tension of the front and rear surfaces 32b and the tension of the front and rear surfaces 34b are balanced with the lower end of the longitudinal member 78 as a fulcrum, so that the posture of the container unit 10 is: It returns to the initial state shown in FIG.

As shown in FIG. 10, when an external force acting on the container unit 10 to incline the container unit 10 so that the tip of the container unit 10 moves to one side in the width direction when viewed from the container front-rear direction, the vertical The member 78 is inclined to one side in the width direction with the lower end of the longitudinal member 78 as a fulcrum. When the longitudinal member 78 is tilted to one side in the width direction with the lower end of the longitudinal member 78 as a fulcrum (when the inverted balance formed by the longitudinal member 78 and the pedestal 56 is inclined forward), the support portion 44 of the spout 40 The distance (the distance L3 in the figure) between the other end in the width direction and the other end in the width direction of the pedestal 56 increases (the inverted balance applies tension to the side membrane at the most appropriate position for suppressing the inclination). Automatically instructs you to put them out). For this reason, the tension generated at the other end side in the width direction on the front and rear surfaces 32b and 34b becomes stronger than the initial tension, and the tilting of the container unit 10 is suppressed.

When the external force for tilting the container unit 10 is released, the tension generated at the other end in the width direction of the front and rear surfaces 32b and 34b and the tension generated at the one end in the width direction are increased. And the lower end of the longitudinal member 78 is used as a fulcrum. Thereby, the posture of the container unit 10 returns to the initial state shown in FIG.

As shown in FIG. 11, when an external force acting on the container unit 10 to incline the container unit 10 so that the tip of the container unit 10 moves to the other side in the width direction when viewed from the container front-rear direction, the vertical The member 78 is inclined to the other side in the width direction with the lower end of the longitudinal member 78 as a fulcrum. When the longitudinal member 78 is inclined to the other side in the width direction with the lower end of the longitudinal member 78 as a fulcrum (when the inverted balance formed by the longitudinal member 78 and the pedestal 56 is inclined forward), the support portion 44 of the spout 40 The distance (the distance L4 in the figure) between one end in the width direction and one end in the width direction of the pedestal 56 is widened (the inverted balance exerts tension on the side membrane at the most appropriate position for suppressing the inclination). Automatically.) For this reason, the tension generated at the one end side in the width direction on the front and rear surfaces 32b and 34b becomes stronger than the initial tension, and the tilting of the container unit 10 is suppressed.

When the external force for tilting the container unit 10 is released, the tension generated at the other end in the width direction of the front and rear surfaces 32b and 34b and the tension generated at the one end in the width direction are increased. And the lower end of the longitudinal member 78 is used as a fulcrum. Thereby, the posture of the container unit 10 returns to the initial state shown in FIG.

As described above, the external force for tilting the container unit 10 acts to increase the tension of at least a part of the front and rear surfaces 32b and 34b as compared with the initial tension. In other words, the external force for tilting the container unit 10 is converted into a tension for pulling at least a part of the front and rear surfaces 32b and 34b by the function of the inverted balance.

Next, a case where an external force sandwiching the bag-shaped container 20 from the front-rear direction acts on the container unit 10 (the balance of the force acting on the container from the front-rear direction is not disrupted. Therefore, the inverted balance is an inverted balance. The holding force (the force holding the container) cannot be detected by tilting).

As shown in FIG. 7, when an external force (arrow F1 in the figure) sandwiching the bag-shaped container 20 from the front-rear direction acts on the container unit 10 when viewed from the container width direction, the bent portion 80a of the urging member 80 It moves to the longitudinal member 78 side (see the two-dot chain line in the figure). When the bending portion 80a of the urging member 80 moves toward the longitudinal member 78, the distance between the upper end 80b and the lower end 80c of the urging member 80 (the distance L10 in the drawing) tends to increase. As a result, the urging force for urging the moving portion 74 toward the pedestal 56 (downward side) becomes stronger (the arch of the urging member 20 (flying beam) detects the clamping force, and the external force is applied to the fulcrum of the inverted balance). Announce presence).

Further, the urging force for urging the moving portion 74 toward the pedestal 56 side (downward) is applied via the pedestal 56 and the band body 50 to the lower end portion of the front and rear surfaces 32b of the front member 32 and the front and rear surfaces 34b of the rear member 34. Is transmitted to the lower end portion. Therefore, the force for moving the lower end of the front and rear surfaces 32b of the front member 32 and the lower end of the front and rear surfaces 34b of the rear member 34 downward is increased (the inverted balance is informed by the urging member 20 (flying beam). Automatically instructs both the front and rear side membranes to apply tension equally evenly). Thereby, the bending rigidity of the bag-shaped container 20 is improved by increasing the tension generated on the front and rear surfaces 32b and 34b as compared with the initial tension.

In this manner, the external force sandwiching the bag-shaped container 20 of the container unit 10 from the front-rear direction is converted into a tension pulling the front-rear surface 32b and the front-rear surface 34b. (With the help of the biasing member 20 (flying beam), the inverted balance can convert the holding force into tension. Specifically, even if the biasing member 20 (flying beam) is eliminated, the inverted balance can be held alone. Although it is possible to convert the force into tension, the side membrane is overused, so the description has been made using the longitudinal member 78 provided with the biasing member 20 (flying beam)).

[Summary] As described above, in the bag-shaped container 20, by mounting the pedestal 56 and the pump 60 on the bag-shaped container 20, the front and rear surfaces 32 b of the front member 32 of the bag body 30 and the rear member 34 are formed. An initial tension in the vertical direction is generated on the front and rear surfaces 34b. Further, the tension generated on the front and rear surfaces 32b and the tension generated on the front and rear surfaces 34b are balanced on the lower end of the longitudinal member 78 as a fulcrum. Thereby, the rigidity of the bag-shaped container 20 against bending and compression is improved, and the posture of the bag-shaped container 20 is stabilized. And, by stabilizing the posture of the bag-shaped container 20, the inclination of the bag-shaped container 20 can be suppressed. Further, the urging member 80 can prevent the bag-shaped container 20 from being squeezed.

In the bag-like container 20, the pedestal 56 is inserted between the bottom 50 b of the band 50 attached to the lower end portions of the front and rear surfaces 32 b and 34 b and the bottom member 38 of the bag body 30. Thereby, the pedestal 56 can be easily attached to and detached from the bag-shaped container 20.

Further, in the container unit 10, similarly to the bag-shaped container 20, the initial tension in the vertical direction is generated on the front and rear surfaces 32 b of the front member 32 of the bag main body 30 and the front and rear surfaces 34 b of the rear member 34, thereby forming the bag-shaped member. The bending rigidity of the container 20 is improved, and the posture of the bag-shaped container 20 is stabilized. And, by stabilizing the posture of the bag-shaped container 20, the inclination of the bag-shaped container 20 can be suppressed.

When the external force that causes the container unit 10 to tilt is released, the tension of the front and rear surfaces 32b and the tension of the front and rear surfaces 34b are balanced with the lower end of the longitudinal member 78 as a fulcrum. It can be returned to the state.

The urging member 80 urges the moving part 74 of the longitudinal member 78 toward the pedestal 56. For this reason, for example, even when the length of the front and rear surfaces 32b and 34b changes over time, the front and rear surfaces 32b of the front member 32 and the front and rear portions of the rear member 34 are compared with the case where the urging member is not provided. The weakening (decreasing) of the initial tension generated on the surface 34b can be suppressed.

Further, the bent portion 80a of the urging member 80 which draws a substantially V-shaped arch is disposed on the front and rear surfaces 32b and 34b with respect to the upper end 80b and the lower end 80c of the urging member 80. Thereby, the urging member 80 can prevent the front and rear surfaces 32b and 34b from being dented by the external force acting on the container unit 10 so as to sandwich the bag-shaped container 20 from both sides. It is with.

Further, the bent portion 80a of the urging member 80 which draws a substantially V-shaped arch is disposed on the front and rear surfaces 32b and 34b with respect to the upper end 80b and the lower end 80c of the urging member 80. Thereby, when an external force sandwiching the bag-shaped container 20 from the front-rear direction acts on the container unit 10, the bent portion 80 a moves toward the longitudinal member 78, thereby urging the moving portion 74 toward the pedestal 56. The power becomes stronger. Further, since the urging force for urging the moving portion 74 toward the pedestal 56 becomes stronger, the tension generated on the front and rear surfaces 32b and 34b becomes stronger than the initial tension. For this reason, the posture of the bag-shaped container 20 can be further stabilized.

The pair of biasing members 80 arranged on the front side and the rear side with respect to the longitudinal member 78 move like a pantograph when the bag-shaped container 20 is sandwiched from both sides. Thus, the external force acting on the container unit 10 so as to sandwich the bag-shaped container 20 from both sides can be easily converted into an urging force for urging the moving portion 74 toward the pedestal 56 side.

Second Embodiment An example of a bag-like container and a container unit according to a second embodiment of the present invention will be described with reference to FIGS. 12A and 12B. In addition, about 2nd Embodiment, a different part from 1st Embodiment is mainly demonstrated.

As shown in FIG. 12A, the bag-like container 12 provided in the container unit 110
In the bag body 30 of No. 0, a projecting portion 136 projecting downward is formed at the lower end portion of the front and rear surfaces 32b of the front member 32 as compared with the upper and lower surfaces 38a of the bottom member 38 which face in the vertical direction. Further, in the bag main body 30 of the bag-shaped container 120, a projecting portion 138 projecting downward compared to the upper and lower surfaces 38 a of the bottom member 38 is formed at a lower end portion of the front and rear surfaces 34 b of the rear member 34.

In addition, locking holes 136a and 138a penetrating the front and back are formed in the overhang portions 136 and 138, respectively. Specifically, two locking holes 136a are formed side by side in the container width direction, and two locking holes 138a are formed so as to face the locking holes 136a in the front-rear direction. In other words, locking holes 136a and 138a are formed in the protruding portions 136 and 138 (an example of a peripheral portion) outside the bottom member 38.

Further, the base 156 has four engagement projections 156a inserted (engaged) into the engagement holes 136a and 138a.

In this configuration, as shown in FIGS. 12A and 12B, the base 156 is attached to the bag-like container 20 by inserting the engagement protrusion 156 a formed on the base 156 into the locking holes 136 a and 138 a. You. On the other hand, the pedestal 156 is detached from the bag-like container 20 by extracting the engagement protrusion 156a formed on the pedestal 156 from the locking holes 136a and 138a. In this manner, the base 156 can be attached to and detached from the bag-shaped container 20.

The other actions of the second embodiment are the same as those of the first embodiment except for the action provided by the provision of the band.

<Third Embodiment> Until now, the side membrane of the bag-shaped container 20 itself has been used as a means for connecting the spout 40 and the pedestal to be separated by pressing the longitudinal member 78 to generate tension (self-standing force). Has been introduced. However, in principle, any other tension can be generated as long as it extends from the spout 40 to the pedestal, and the tension need not be limited to the side membrane of the bag-shaped container.

FIG. 16A shows a mechanism for generating tension using the hanging cord 90 as a connection between the spout 40 and the pedestal 92. Although the shape of the bag-like container 20 into which the longitudinal member 78 is inserted is omitted to clearly illustrate the structure, the bag-like container 20 is present in the central space surrounded by the hanging straps 901, 902, 903, and 904. Then, imagine that the spout 40 on the upper part of the bag-shaped container is captured by fitting into the hole of the spout holding portion 915. It can be easily understood that this is equivalent to FIG. 23 of Japanese Patent No. 6329298, which is the original application of the crust-shell type flexible packaging container and which is also concluded by priority with the present application. Therefore, the hanging cord 90 of FIG. 16A has an independent force.

A self-supporting (tensile) hanging cord 90 surrounds the stringer in a tensioned state like a harp. In FIG. 16 (a), the drawing is simply drawn with four narrow hanging straps 90 standing vertically, but the strap does not need to be thin, and even a strip-shaped membrane having a width works equivalently. . FIG. 17 is a diagram in which the hanging strings 902 and 903 of FIG. 16 are combined with a hanging film 905, and the hanging strings 901 and 904 are combined with a hanging film 906. It is not necessary to form a membrane between the hanging strings 091 and 902 and between 903 and 904. Therefore, the suspension membranes 905 and 906 face forward and backward, and the longitudinal members are also arranged in the center of the suspension membranes in parallel with this membrane, so that when viewed from the side, the structure is such that three grids are arranged. The side membrane of the bag-shaped container is attached so as to surround the gap of the lattice. Of course, the bag-shaped container does not fall down because it is surrounded and supported by the hanging strap 90 whose outer periphery is tensioned or the strip-shaped hanging membranes 905 and 906 having a wide width. Moreover, the bottom of the bag-shaped container is fixed between the lower end of the vertical member 78 and the pedestal 56, and the upper portion of the bag-shaped container is also fixed with the spout by the vertical member. There is no change in position. That is, the bag-shaped container maintains its self-standing posture even when an external force acts. For the above reasons, in the text, the cage that imitates this lattice-shaped cage is named "quasi-shelled cage type holder".

The effect obtained from the basket-shaped upholstery structure can be obtained also in Embodiments 1 to 3 introduced in FIG. 1 and FIG. 12A. Nevertheless, it is sufficient if a tension is generated in the side film of the bag-shaped container 20. Why is the cage-shaped structure provided outside the bag-shaped container and the third configuration? . The purpose is to enable uprightness to be obtained by the upholstery structure even in a normal bag-shaped container. The embodiment introduced in FIG. 1 and FIG. 12A requires a unique structure of the band 50 or the locking holes 136a and 138a for mounting the pedestal on the bottom surface of the bag-shaped container. This means that existing production equipment requires some modifications. From the producer's point of view, there is naturally a need to reuse existing equipment as it is. Therefore, it is easy to imagine that a method is desired in which a normal bag-shaped container without the band 50 and the locking holes 136a and 138a, which is created from the conventional production equipment, can benefit from the crust structure.

As mentioned above, the basket-shaped crust structure simply puts the bag in a virtual basket formed by a hanging string or a band-like membrane, so if it is a container with a spout, it can be used for all types of bag-like containers it can. That is, versatility (industrial utility value) is dramatically improved. This is the reason that the semi-shelled basket type holder was introduced. Further, tension is generated by the inclination of the balance because the hanging string provided in the holder or a film equivalent thereto is used. Since the side of the bag-shaped container does not generate tension as in Embodiments 1 to 3, However, it is not necessary to assume the membrane strength of the bag-like container assuming tension, and it is possible to concentrate solely on preventing the contents from leaking out as before, which has the effect of increasing the degree of freedom in bag design. Can be

Although not particularly mentioned in the description of the above-described first to third embodiments, in the present embodiment, the spout-provided top material is attached to the upper surface, the bottom material is attached to the lower surface, and the upper surface and the lower surface are joined. A pedestal is connected to the lower ends of the side portions of the pair of front and rear surfaces, and the vertical member inserted into the bag from the opening of the spout is attached to the spout to be pushed down (tightened down), and the lower end of the vertical member By pressing the bottom material against the pedestal to spread the space between the spout and the pedestal and applying sufficient initial tension in the vertical direction to the side of the main body connected to the pedestal, bending and compression acting on the container can be prevented. The bottom material is held between the pedestal and the longitudinal member by using the phenomenon that the force in any direction can be aligned with the longitudinal member as a fulcrum and transferred to the side of the main body as tension. At the same time as fixing, the side of the body is attached to the core of the bag by the tension created on the side of the body. Also antagonize the external force in the structure used as branch lines holding the posture of the stringer through, to enhance the upright of the bag.
