From this point of view, although the improvement of the opening state of the nozzle portion can be seen from the previous one, from the viewpoint of sufficiently maintaining the opening of the nozzle portion, the first valley fold line (6) and the second valley fold line (7 ) The mountain fold line (8) is formed so deeply that there are problems such as improvement of the film thickness of the packaging bag and cost increase associated therewith to prevent breakage at each fold line portion. In addition, the processing is complicated due to the formation of a plurality of fold lines of mountain fold lines and valley fold lines. Furthermore, there is a problem in that each fold line portion is conspicuous and the nozzle portion of the packaging bag is wrinkled and looks bad.
[0005]
In view of these points, the present invention provides a liquid container with a nozzle that has a nozzle that opens well and has a good appearance, even if it is not a specially thick plastic film or sheet, due to the specified simple broken line. Is to provide.
[0006]
[Means for Solving the Problems]
The standing-type nozzle-equipped liquid storage container of the present invention forms a liquid storage portion inside by sealing the periphery of the plastic film or sheet surrounding the upper side, the left and right side sides, and the bottom, and the lower part swells The upper part is narrowed , and the nozzle is formed so as to face obliquely upward between a seal part extending in the vertical direction on one side part and a recess formed in the upper side part in an upward V shape. In the standing liquid storage container with a nozzle,
Below the extension of the depression, a first crease is formed, which forms a valley where the inclined surface on the nozzle side falls and drops toward the bottom of the depression when the liquid is dispensed ,
From the tip of the nozzle to the lower part of the first fold line, in a curved shape with a bulge to the one side part side, through the lower part of the first fold line and extending to the upper side part side The second crease which becomes a mountain having a shape surrounding the depression is formed , and the technical means of claim 1.
[0007]
As a result, an action force due to the liquid moving by gravity toward the nozzle when the liquid is dispensed acts on the upper portion including the nozzle, and the fold line is formed as a trough toward the bottom of the V-shaped depression, and the right and left An inclined surface toward the valley is clearly formed, and accordingly, the nozzle and the spout portion are favorably opened outward. And when pushing the bottom part or middle part of a liquid storage container in order to accelerate | stimulate liquid pouring, the said seal part extended in the vertical direction to the said side part acts, and the said hollow has the V-shaped opening width | variety. As the acting force by the liquid acting toward the nozzle increases, the V-shaped opening width of the V-shaped depression narrows and the valley deepens, so the inclination toward the valley becomes steeper. As a result, the nozzle and the spout part open more favorably in the outward direction.
[0008]
Further, since there is a streak, a sloped ridge line formed on the nozzle side of the valley is formed by the streak, and a sloped surface is formed surrounding the V-shaped depression and toward the valley. As the valley becomes deeper, the inclination toward the valley becomes steeper, and accordingly, the nozzle and the spout part open favorably outward.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
First, it will be described with reference the structure of a nozzle with the liquid container is a studied technique upon reaching the present invention in FIGS. The liquid storage container 1 includes liquid detergent, liquid softening agent, liquid soap, and the like as liquid contents to be filled therein, and a bag for storing the contents in a container such as another bottle for refilling. It is a standing-type liquid storage container with a nozzle called a standing pouch, which can be placed on a table or the like with its bottom portion facing down. The liquid storage container 1 has a configuration in which a peripheral portion of a pair of plastic films or sheets positioned corresponding to the surface is sealed to form a liquid dispensing nozzle in a part. Specifically, the surface material 2, the back surface material 3 and the bottom surface material 4 which are positioned corresponding to the surface are heat-sealed at the peripheral portion as described later and configured in a bag shape. The back material 3 and the bottom material 4 are each made of a plastic film or sheet of any one of a transparent material, an opaque material, and a translucent material.
[0010]
This film or sheet is composed of, for example, a two-layer structure in which the outer layer is a nylon film and the inner layer is a linear low density polyethylene film, the outer layer is a biaxially stretched nylon film, and the intermediate layer is a uniaxially stretched polyolefin film. Three-layer structure with inner layer made of linear low-density polyolefin, outer layer with nylon film, intermediate layer with aluminum vacuum-deposited polyethylene terephthalate film, inner layer with three-layer structure made of linear low-density polyethylene film Also, the outer layer is an aluminum oxide-deposited polyethylene terephthalate film, the intermediate layer is a nylon film, the inner layer is a three-layer structure consisting of a linear low density polyethylene film, the outer layer is a polyethylene terephthalate film, and the outer intermediate layer is aluminum. Foil, inner middle layer Nylon film, a configuration of a four-layer structure in which the inner layer is made of linear low density polyethylene film.
[0011]
The peripheral bonding seal portion 5 between the surface material 2 and the back surface material 3, the lower portion of each of the surface material 2 and the back surface material 3, and the bonding seal portion 6 of the bottom surface material 4 spreading forward and backward are respectively heat-sealed, and the surface material A storage portion 7 for filling contents is formed in the interior of the liquid storage container 1 between the back material 3 and the back material 3. As a barrier film provided with an inorganic compound vapor deposition layer by depositing aluminum or another inorganic compound by a method such as vacuum vapor deposition, the outer layer is transparent, and the liquid storage container 1 having an appearance of silver or the like is provided. You can also.
[0012]
As described above, the liquid storage container 1 seals the peripheral portion around the upper side portion 10, the left side portion 11, the right side portion 12, and the bottom portion 13 of the plastic film or sheet constituting the surface material 2 and the back surface material 3. A liquid storage portion 7 is formed inside, and a liquid pouring nozzle 8 is formed in one corner portion 15 (the left corner portion in FIG. 1) on the upper side portion. It is a container.
[0013]
In the liquid storage container 1, the nozzle 8 has a spout portion 9 formed by cutting at a tip portion, and a seal portion 5 </ b> A (in the drawing, extending vertically to the left side portion 11 or the right side portion 12. A left side portion 11) and a recess 14 formed in the upper side portion 10 and opened upward in a V shape are partitioned and formed in the corner portion 15 so as to face obliquely upward.
[0014]
Further, the recess 14 is prevented from tearing from the bottom by providing roundness at the bottom. The spout portion 9 can be formed by manually tearing the surface material 2 and the back surface material 3 from the notch 16 formed by cutting the seal portion 5A, and the spout portion 9 can be cut and formed without a tool such as scissors. .
[0015]
The liquid storage container 1 forms a content filling storage portion 7 having a shape in which the bottom portion spreads back and forth by sealing the peripheral portion around the upper side portion 10, the left side portion 11, the right side portion 12, and the bottom portion 13. In order to fill the liquid container 1 with the liquid, the other peripheral portion is sealed except for the portion 20 of the upper side portion 10 on the right side of the recess 14 in FIG. The filling of the liquid into the liquid storage container 1 is usually performed in a factory by inserting a liquid injection nozzle into an opening between the surface material 2 and the back surface material 3 formed in the unsealed portion 20. After this filling, the contents filling storage unit 7 is deaerated, and the unsealed portion 20 is heat sealed.
[0016]
The liquid storage container 1 filled with the liquid in this way has a shape in which the bottom portion swells back and forth in the standing state, and the upper side portion is brought into close contact or contact with the surface material 2 and the back surface material 3 by deaeration. Become. For this reason, the ridgeline 21 of the shape which spread in the substantially V shape or U shape toward the left side part 11 and the right side part 12 from the upper-lower intermediate part of the surface material 2 and the back surface material 3 is formed naturally. The inside of the ridge line 21 is an inclined surface 22 that is inclined upward from the bulging portion. For this reason, the liquid level in the standing state is a position indicated by 19. The shape of the ridge line 21 is slightly different depending on the amount of the filled liquid and the material of the surface material 2 and the back surface material 3. However, as shown by 21A or 21B in FIG. From the upper and lower intermediate portions, the shape expands in a substantially V shape or U shape toward the left side portion 11 and the right side portion 12.
[0017]
The above-mentioned liquid storage container with a nozzle seals the periphery of the plastic film or sheet around the top, left and right sides, and the bottom to form a liquid storage inside, and the lower part is swollen and the upper part is constricted. In the stationary type liquid storage container with a nozzle, it is inclined obliquely upward between a seal portion 5A extending in the vertical direction on the side portion and a recess 14 formed in the upper side portion and opened upward in a V-shape. The nozzle 8 is formed, and below the extension of the recess 14, a slant surface 24 </ b> A on the nozzle 8 side drops when the liquid is poured out to form a streak that forms a valley that descends toward the bottom of the recess 14. .
[0018]
In the study technique , an inclination 24 is formed at the opposite positions of the front and back surfaces of the liquid container 1 so as to surround the V-shaped depression 14 when the liquid is dispensed, and the inclination 24 is divided into left and right inclined surfaces 24A and 24B. A bent line 40 is formed below the V-shaped depression 14. In other words, the crease 40 acts as a valley in which the inclined surface 24A on the nozzle 8 side and the inclined surface 24B on the opposite side fall from both sides and descend toward the bottom of the V-shaped recess 14. 14 is a streak that forms a trough descending toward the bottom of 14.
[0019]
The folding line 40 is formed in a ruled line shape slightly depressed in the surface material 2 and the back surface material 3 by embossing so as to form a symmetrical shape at the same position of the surface material 2 and the back surface material 3. For this reason, at the time of liquid extraction, as described later, an inclination 24 is formed so as to surround the V-shaped depression 14 by an acting force accompanying the movement of the internal liquid. The bend line 40 divides the inclination 24 into left and right inclined surfaces 24 </ b> A and 24 </ b> B to form a linear valley bottom that descends toward the bottom of the V-shaped recess 14. For this reason, since the purpose can be achieved if the bent line 40 is formed in the portion of the slope 24, it does not need to be formed so long. The form state shown, the folding bars 40, ends with ridge portions 25 of the mountain shape the inclination 24 extends from the seal portion of the bottom of the V-shaped recess 14 downwardly, is a position above the liquid level 19 .
[0020]
With such a configuration, when the liquid is poured from the liquid storage container 1 to the other container 27, the force of the liquid moving toward the nozzle portion 8 acts on the spout portion 9, and the seal on the left side 11 of FIG. 1 or FIG. As shown in FIGS. 3 and 4, the inclined surface 24 is formed so as to surround the depression 14 in a state where the collapse of the nozzle portion 8 is suppressed due to the smooth action of the portion 5 </ b> A. And the inclined surface 24A, 24B which goes to this trough is clearly formed in the right and left as a trough which inclines the bending line 40 toward the bottom of the V-shaped hollow 14, and the nozzle 8 and the spout part 9 are formed in connection with it. Open well in the outward direction.
[0021]
And when pushing the bottom part or middle part of the liquid storage container 1 in order to accelerate | stimulate liquid pouring, the seal | sticker part 5A extended in the vertical direction to the side part acts, and the hollow 14 has the V-shaped opening width. As the acting force by the liquid acting toward the nozzle 8 increases, the V-shaped opening width of the V-shaped recess 14 tends to narrow, and the valley deepens, so the inclination toward the valley becomes steep, As a result, the nozzle 8 and the spout portion 9 open more favorably in the outer direction. As described above, when the bottom or intermediate portion of the liquid storage container 1 is strongly pressed, the ridge line portion 25 forming the inclined surface 24 becomes sharper and slightly bends in the middle as shown by the dotted line 25A in FIG. There is.
[0022]
The bent line 40 may form a straight line as shown by a solid line in the figure, but by forming a curved line that swells toward the nozzle 8 as indicated by a dotted line 40A, the inclined surface 24A causes the nozzle 8 to bulge outward. Can be encouraged.
[0023]
It will now be described based on the structure of the implementation form of the nozzle with the liquid container of the present invention in FIGS. 5 to 7. 5 to 7, reference characters the same parts in FIGS. 1 to 4 denote the same parts, and a description thereof will be Ru similar der to what was described with reference to FIGS. 1 to 4.
[0024]
That is, in the liquid storage container 1 of the present invention , the above-described folding line 40 is referred to as a first bending line 40, and a second bending line 41 is formed with respect to the first bending line 40. The second bent line 41 is a line that forms a mountain from the tip of the nozzle 8 toward the root of the nozzle 8, and the root 17 of the nozzle 8 from the tip of the nozzle 8 (the spout 9 or the vicinity thereof). The central portion of the nozzle 8 extends toward the lower portion of the first fold line 40 along the wall 18 of the recess 14 on the nozzle 8 side. The first crease 40 and the second crease 41 are formed by embossing so as to form a symmetrical shape at the same position on the front surface material 2 and the back surface material 3. The first crease 40 is formed in a ruled line shape slightly recessed in the surface material 2 and the back material 3, and the second crease 41 is formed in a ruled line shape slightly bulging in the surface material 2 and the back material 3. The
[0025]
The nozzle 8 of the liquid container 1 of the present invention has a seal portion 5A extending in the vertical direction on the left side portion 11 or the right side portion 12 (left side portion 11 in FIG. 5), and upward formed on the upper side portion 10. A section 14 is formed in the corner portion 15 so as to face diagonally upward by a V-shaped recess 14. For this reason, when the liquid is poured from the liquid storage container 1 to the other container 27, the second crease 41 for inflating the nozzle 8 well is the surface of the liquid storage container 1 when the liquid storage container 1 is standing upright. It is not on the extension of the ridgeline 21 (21A or 21B) that is naturally formed, but rather above the ridgeline 21 (21A or 21B).
[0026]
This is because the nozzle 8 is formed so that the corner portion 15 faces obliquely upward. For this reason, the second crease 41 extends toward the lower part of the first crease 40 .
[0027]
Second folding bars 41, in order to form an inclined surface 24 so as to surround the in recess 14 as discussed later, the tip portion of Roh nozzle 8 (spout 9 or near) the first folding bars from The entire upper part extends to the left side of FIG. 5 and gently curves toward the recess 14 while extending to the lower side of FIG. 5, and passes through the lower part of the first bent bar 40 as shown in FIGS. 5 and 6. It extends to the portion indicated by the alternate long and short dash line 41 </ b> A so as to reach the portion 10 side and is formed in a shape surrounding the recess 14.
[0028]
With such a configuration, when the liquid is poured from the liquid storage container 1 to the other container 27, the force of the liquid moving toward the nozzle portion 8 acts on the spout portion 9, and the seal on the left side 11 of FIG. 5 or FIG. In a state where the collapse of the nozzle portion 8 is suppressed due to the slipping action of the portion 5A, as shown in FIG. A surface 24 is formed. And the 1st crease 40 or 40A is made into the valley which goes to the bottom of the V-shaped hollow 14, and inclined surface 24A, 24B which goes to this valley is formed in the right and left. Thus, because the second folding bars are present, the ridgeline portion 25 of the inclined surface 24A which is formed in the nozzle 8 side of the valley than in FIG. 4 is highlighted as angulate by the second folding bars 41 Thus, the action of opening the nozzle 8 and the spout 9 in the outward direction is strengthened. By pressing the bottom part or the middle part of the liquid storage container 1, the inclination toward the valley becomes steeper as the valley deepens, and the nozzle 8 and the spout part 9 are favorably opened outwardly.
[0029]
When the liquid is poured from the liquid storage container 1 to the other container 27, if the bottom or intermediate portion of the liquid storage container 1 is pressed, the fall of the nozzle portion 8 is suppressed due to the slipping action of the seal portion 5A on the left side 11. As shown in FIG. 7, the depression 14 is inclined to the depression 14 side as the spout portion 9 is tilted toward the depression 14 as the V-shaped opening is narrowed and moved toward the bottom as indicated by a one-dot chain line 26. The deeper the trough formed on the streak 40, the steeper the slope toward that trough, the stronger acting force that opens the spout portion 9 works, and the spout portion 9 opens greatly. As described above, when the bottom portion or the intermediate portion of the liquid container 1 is strongly pressed, the ridge line portion 25 serving as the boundary portion forming the inclined surface 24 is slightly bent along the dotted line 25A in FIG. There is a case.
[0030]
As described above , the second crease 41 extends to the portion indicated by the alternate long and short dash line 41 </ b> A in FIGS. 5 and 6 and is formed in a shape surrounding the recess 14. As a result, the ridge line portion 25 of the inclined surface 24 surrounding the V-shaped depression 14 becomes clearer, and the depth of the valley becomes stronger due to the action force of the liquid moving toward the nozzle portion 8. The exit part 9 opens well in the outward direction.
[0031]
As described above, in the liquid storage container 1 of the present invention, the slanted surface 24A on the nozzle 8 side drops when the liquid is dispensed, and a streak that forms a valley that descends toward the bottom of the recess 14 is formed below the extension of the recess 14. and, further, in addition to the muscle to be the trough, thus the tip of the nozzle 8 and this was muscle as a mountain is formed toward the root portion of the nozzle 8, good nozzle and spout portion outward in which it is possible to achieve the this and effect equal to open.
[0032]
The liquid container 1, when pouring the liquid into another container 27, is performed by inserting the nozzle 8 to the mouth 28 of the container 27 as shown in FIGS. 3 and 7, in this case, is located beside the nozzle 8 Of the seal portion 5 extending in the vertical direction to the side portion 11, a step portion 29 that contacts the edge of the mouth 28 of the container 27 is formed in the seal portion 5 </ b> A with respect to the nozzle 8. Thus, the depth at which the nozzle 8 enters the mouth 28 of the container 27 is limited, and the nozzle 8 is prevented from being crushed when the nozzle 8 enters deeply.
[0033]
As described above, in order to prevent the nozzle 8 from collapsing, the seal portion 5A needs to maintain a smooth strength. The seal portion 5A is formed by recessing the step portion 29, but the seal portion 5A is formed with a seal portion 5A having an upper seal width larger than that of the lower portion of the joint portion 5, By forming the step portion 29 in the large seal width portion, the above-described strength is maintained.
[0034]
The spout portion 9 is opened by manually breaking from the notch 16 portion. In order to facilitate this breakage, a grip portion 30 that is easily grasped by a finger is formed on the upper portion of the notch 16. With this configuration, the seal portion 5 </ b> A next to the nozzle 8 has a shape in which a recess 31 in which the notch 16 and the stepped portion 29 are formed apart from each other is present.
[0035]
In the above embodiment, the nozzle 8 is formed so as to be inclined obliquely upward in the upper left corner of the liquid storage container 1. In contrast, the nozzle 8 is directed obliquely upward in the upper right corner of the liquid storage container 1. It may be formed.
[0036]
The present invention is not limited to the above-described embodiments, and various modifications can be considered without departing from the technical scope of the present invention, and the various embodiments related thereto are included.
[0037]
【Effect of the invention】
According to the present invention, when the liquid is poured out, an action force due to the liquid moving by gravity toward the nozzle acts on the upper part including the nozzle, and the folding line is formed as a trough toward the bottom of the V-shaped depression. In addition, an inclined surface toward the valley is clearly formed, and accordingly, the nozzle and the spout portion are favorably opened outward. And when pushing the bottom part or middle part of a liquid storage container in order to accelerate | stimulate liquid pouring, the seal | sticker part extended in the vertical direction on the said side part carried out a snap action, and the said hollow became the V-shaped opening width | variety. As the acting force by the liquid acting toward the nozzle increases, the V-shaped opening width of the V-shaped depression tends to narrow and the valley deepens, so the inclination toward the valley becomes steep, Along with this, the nozzle and the spout part open more favorably in the outward direction.
[0038]
Further, since there is a streak, a sloped ridge line formed on the nozzle side of the valley is formed by the streak, and a sloped surface is formed surrounding the V-shaped depression and toward the valley. As the valley becomes deeper, the inclination toward the valley becomes steeper, and accordingly, the nozzle and the spout part open favorably outward.
