Description

The present invention relates to a pouch having a gusset portion.

Conventionally, a bag-shaped gusseted pouch formed from a resin film has been known as a container for containing fluid contents such as drinking water (see, for example, Patent Document 1).

Further, as disclosed in Patent Document 1, a pouch with a gusset is operated in a so-called back-in-box format at the time of use (when the contents are poured out), at the time of display, at the time of transportation, etc., that is, an exterior case. It is also known to house and operate a pouch with a gusset inside.

Japanese Unexamined Patent Publication No. 2012-1216111

However, since the resin film constituting such a gusseted pouch has flexibility, the fluidity of drinking water or the like as shown in FIG. 26 is particularly high when the gusseted pouch is formed in a large capacity. Due to the weight of the contents having a swelling, so-called body swelling may occur in the lower portion of the pouch body.

When the above-mentioned body swelling occurs, it is necessary to secure a large installation space for the pouch with a gusset during its use, display, transportation, etc., and when operating in a bag-in-box format, it has a gusset. Considering the swelling of the pouch, it is necessary to give strength to the outer case.

Therefore, the present invention solves these problems, and an object of the present invention is to provide a pouch that realizes a narrowing of an installation space with a simple configuration.

The pouch of the present invention is a pouch having a gusset portion, and includes a pouch main body and an inner support member arranged in the pouch main body, and the pouch main body includes a content accommodating portion and the content accommodating portion. The inner support member has a first fixed portion and a second fixed portion that face each other with the portions sandwiched therein, and the inner support member is attached to the first fixed portion fixed to the first fixed portion and the second fixed portion. By having the second fixed portion fixed, the above-mentioned problem is solved.

According to the present invention, it is possible to prevent the first fixed portion and the second fixed portion of the pouch body facing each other with the content accommodating portion from being separated from each other by the inner support member. It is possible to maintain the overall shape of the pouch containing the pouch and suppress the so-called body swelling that causes the lower portion of the pouch body to swell due to the weight of the fluid contents such as drinking water. As a result, the installation space of the pouch can be narrowed during use, display, transportation, etc., and when the pouch is operated in a bag-in-box format, the outer case that houses the pouch has high strength. It is possible to eliminate the need to make it.

The spout 60 is formed of a synthetic resin or the like, and is attached to the pouch body 20 to function as a spout for the contents.
In the present embodiment, as shown in FIG. 1, the spout 60 is arranged between the front side film 30 and the back side film 40 at the sealing portion 23 on the top side of the pouch 10, and is (the first) of the front side film 30 by heat welding. It is fixed to the 3 heat welding region 33) and the back side film 40 (the third heat welding region 43).
As shown in FIG. 1, the spout 60 is mounted at a position closer to one side (left side in FIG. 1) than the central portion of the seal portion 23 on the top side of the pouch 10.

In the present embodiment, when the pouch 10 is used (when the contents are poured out), the top of the pouch 10 equipped with the spout 60 is turned laterally, and the side portion of the pouch 10 on which the gusset portion 22 is formed is lowered. The pouch 10 is used in a state of facing. At this time, from the viewpoint of arranging the spout 60 at a lower position and smoothly pouring out the contents, the pouch 10 is placed on the mounting surface with the left side of the pouch 10 of FIG. 1 facing downward. It is preferable to install it.

As shown in FIG. 2, the inner support member 70 is arranged in the pouch main body 20 (contents accommodating portion 21), and in the present embodiment, the inner support member 70 has a rectangular shape (with a heat welding layer on at least one surface thereof). Or it is formed as a flexible resin film (or almost rectangular).

As shown in FIG. 3, the inner support member 70 has a first fixing portion 71 fixed to the first fixing portion 24 of the pouch body 20 on one end side in the longitudinal direction, and sandwiches the content accommodating portion 21. A second fixed portion 72 to be fixed to the second fixed portion 25 of the pouch body 20 facing the first fixed portion 24 is provided on the other end side in the longitudinal direction thereof.

As shown in FIGS. 1 and 3, the first fixing portion 71 faces the heat welding layer of the front side film 30 and the heat welding layer of the back side film 40 at the sealing portion 23 on the top side of the pouch 10. It is arranged between the front side film 30 and the back side film 40 in a state of being folded in half so as to be formed, and is heat-welded to the front side film 30 and the back side film 40. In the present embodiment, as shown in FIG. 1, a part of the seal portion 23 on the top side of the pouch 10 functions as the first fixed portion 24 of the pouch body 20.

As shown in FIGS. 1 and 3, the second fixing portion 72 faces the heat welding layer of the front side film 30 and the heat welding layer of the back side film 40 in the seal portion 23 on the bottom side of the pouch 10. It is arranged between the front side film 30 and the back side film 40 in a state of being folded in half so as to be formed, and is heat-welded to the front side film 30 and the back side film 40. In the present embodiment, as shown in FIG. 1, a part of the seal portion 23 on the bottom side of the pouch 10 functions as the second fixed portion 25 of the pouch body 20.

In the first fixing portion 71 and the second fixing portion 72, the inner side surfaces of the inner support member 70 in the folded state are also heat-welded to each other. For example, by providing heat-welding layers on both sides of the inner support member 70 or by using the inner support member 70 as a single film of a heat-weldable material, the inner side surfaces of the inner support member 70 can also be heat-welded to each other.

Further, as shown in FIG. 3, the inner support member 70 has a third fixing portion 73 fixed to the third fixing portion 26 of the pouch body 20 on one end side in the lateral direction thereof, and also has a content accommodating portion. A fourth fixed portion 74 to be fixed to the fourth fixed portion 27 of the pouch body 20 facing the third fixed portion 26 with 21 sandwiched therein is provided on the other end side in the lateral direction.

As shown in FIG. 2, the third fixing portion 73 is arranged in a state where the heat welding layer faces the heat welding layer on the inner side surface side of the front side film 30, and is heat welded to the inner side surface of the front side film 30. Has been done. In the present embodiment, a part of the inner side surface of the front side film 30 functions as the third fixed portion 26 of the pouch body 20.

As shown in FIG. 2, the fourth fixing portion 74 is arranged in a state where the heat welding layer faces the heat welding layer on the inner side surface side of the back side film 40, and is heat welded to the inner side surface of the back side film 40. Has been done. In the present embodiment, a part of the inner side surface of the back side film 40 functions as the fourth fixed portion 27 of the pouch body 20.

As described above, in the present embodiment, the fixed portions 71, 72, 73, 74 of the inner support member 70 are fixed to the fixed portions 24, 25, 26, 27 of the pouch main body 20, so that the pouch main body 20 is fixed. The overall shape can be maintained, and the pouch body 20 is placed with the bottom side of the pouch body 20 (the side opposite to the side on which the spout 60 is attached) facing down, especially during display or transportation. Even when placed on the surface, it is possible to suppress the swelling of the body in which the front side film 30 and the back side film 40 are separated from each other.

Further, in the present embodiment, since the fixing portions 71, 72, 73, 74 of the inner support member 70 are fixed to the pouch body 20 by heat welding, a seal for forming the pouch body 20 into a bag shape. When forming at least a part of the portion 23 (that is, when the front side film 30, the back side film 40, and the gusset portion film 50 are heat-welded to form at least a part of the seal portion 23), the pouch body 20 is formed. Heat welding of the inner support member 70 can also be performed at one time.

In the present embodiment, when the inner support member 70 is heat-welded to the pouch body 20, the inner support member 70 is folded in half between the front side film 30 and the back side film 40 as shown in FIG. By arranging the front side film 30, the back side film 40, and the inner support member 70 by sandwiching the front side film 30, the back side film 40, and the inner support member 70 with a pair of heat welding jigs 90, a part of the area between the front side film 30 and the inner support member 70 facing each other (specifically, The fourth heat-welded region 34, the first fixing portion 71, the second fixing portion 72, and the third fixing portion 73) shown in FIG. 3 are heat-welded, and one between the facing surfaces of the back side film 40 and the inner support member 70. Part regions (specifically, the fourth heat welding region 34, the first fixing portion 71, the second fixing portion 72, and the fourth fixing portion 74 shown in FIG. 3) are heat welded. Here, when both sides of the inner support member 70 are layers having heat-weldability and it is not desirable that the inner surface folded in half is heat-welded, the inner support member 70 folded in half in the step. In order to prevent the inner side surfaces (opposing surfaces) of the above from being heat-welded to each other, it is preferable to arrange the baffle plate 80 between the inner side surfaces (opposing surfaces) of the two-folded inner support member 70. When both sides of the inner support member 70 have heat welding properties, materials having different welding temperatures are used for each side, and the inner surfaces folded in half are heat-welded by controlling the welding temperature, or vice versa. Although it is possible to prevent heat welding to the surface, it is possible to prevent the inner side surfaces (opposing surfaces) of the inner support members 70 from being heat-welded to each other by using the baffle plate 80.
Even if both sides of the inner support member 70 are not layers having heat welding properties, the baffle plate 80 can be used at the time of heat welding.
Further, the step of heat-welding the inner support member 70 to the front side film 30 and the back side film 40 is a step of forming a seal portion 23 for forming the pouch body 20 into a bag shape (that is, with the front side film 30). The step of heat welding between the back side film 40 and the gusset film 50) may be performed at the same time, or may be performed separately.

Further, as shown in FIG. 3, the inner support member 70 is formed so as to penetrate in the front and back directions thereof, and has a plurality of hole-shaped distribution portions 75 for distributing the contents. As in the present embodiment, the entire outer edge of the inner support member 70 is fixed to the inner wall of the content accommodating portion 21, and the inside of the content accommodating portion 21 is divided into a plurality of (two) spaces by the inner support member 70. Even in this case, the contents can be flowed in the contents accommodating unit 21 through the distribution unit 75.

Further, as shown in FIG. 2, the inner support member 70 has a non-welded region (a portion inside the fixing portions 71 to 74 where the flow portion 75 is formed) parallel to the gusset portion film 50. Have been placed.

Further, as shown in FIGS. 1 and 3, the seal portion 23 on the top side of the pouch 10 is formed with a handle hole 28 for the user to hold the pouch 10 through his / her hand or finger. At least a part (all in the present embodiment) of the handle hole 28 is formed so as to penetrate a portion where the front side film 30, the back side film 40, and the first fixing portion 71 overlap.

Next, the pouch 10 according to the second embodiment of the present invention will be described with reference to FIGS. 12 to 15. Here, since the second embodiment is exactly the same as the first embodiment described above except for a partial configuration, the description of the configuration other than the differences will be omitted.

Conventionally, there is a spout pouch having gusset portions on the left and right sides of the pouch, and there is a spout pouch having a gripping hole portion (Patent Document 2: Japanese Patent Application Laid-Open No. 2017-210257). This type of pouch is housed in a box-shaped case such as a cardboard case during transportation, and the pouch width decreases from the lower part to the upper part of the spout pouch. Therefore, when the spout pouch is stored in the box-shaped case, there is a large gap between the spout pouch and the inner wall of the box-shaped case, and there is a problem that the storage efficiency is poor. The pouch 10 shown in the second embodiment is a pouch for the purpose of solving this problem.

In the second embodiment, the overall shape of the pouch 10 is adjusted to a shape suitable for storage, display, etc. (in the present embodiment, the overall shape of the pouch 10 is a substantially rectangular parallelepiped) to improve the storage and displayability of the pouch 10. As shown in FIGS. 12 and 13, crease processing portions 35, 45, and 56 are formed at predetermined positions of the films 30, 40, and 50.

Specifically, first, the crease processing portions 35, 45, 56 are bent at the predetermined locations of the films 30, 40, 50 by deforming the predetermined locations of the films 30, 40, 50 into an uneven shape in the thickness direction. It is a part that has been processed to facilitate the occurrence of.

As shown in FIGS. 12 and 13, the front side film 30 and the back side film 40 extend in the left-right direction at two locations, an upper side (top side of the pouch 10) and a lower side (bottom side of the pouch 10). First heat welding in which the crease processing portions 35a and 45a of 1 and the upper side (more specifically, the front side film 30 and the back side film 40 are heat-welded to each other) above the first crease processing portions 35a and 45a on the upper side. In the lower end positions of the regions 31 and 41), the second creases 35b and 45b extending in the left-right direction are provided.

As shown in FIG. 12, the first crease processing portions 35a and 45a are formed so that the outer surface side of the films 30 and 40 is convex so as to be easily bent.
Further, one of the second crease processing portions 35b and 45b is formed so that the films 30 and 40 are easily bent so that the outer surface side of the films 30 and 40 is convex, and the second crease processing portion 35b is formed. The other of 45b is formed so that the outer surface side of the films 30 and 40 is concave so that the films 30 and 40 are easily bent.
Further, the distance in the vertical direction between the first crease processing portions 35a and 45a and the second crease processing portions 35b and 45b and the distance from the second crease processing portions 35b and 45b to the upper ends of the films 30 and 40. The distance from the second crease processing portions 35b and 45b to the upper ends of the films 30 and 40 is set to be smaller, so that the second creases of the films 30 and 40 are set as shown in FIG. When the upper side of the processed portions 35b and 45b is tilted, it is possible to prevent the upper side of the films 30 and 40 from protruding from the second crease processed portions 35b and 45b.

Further, as shown in FIGS. 12 and 13, the gusset film 50 is crease-processed so as to extend in the left-right direction at two upper and lower positions set at the same height positions as the first crease-processed portions 35a and 45a. It has a part 56.
The crease processing portion 56 is formed so that the outer surface side of the gusset portion film 50 is convex so that the gusset portion film 50 is easily bent.

As described above, by forming the crease processing portions 35, 45, 56 on the films 30, 40, 50, as shown in FIG. 12, the entire shape of the pouch 10 can be made into a substantially rectangular parallelepiped suitable for storage and the like. At the same time, the sealing portion 23 on the top side of the pouch 10 (the front side film 30 side or the side above the second crease processed portions 35b and 45b of the back side film 40) is tilted to either the front side film 30 side or the back side film 40 side. It will be easier.

In the example shown in FIG. 12, the position where the spout 60 becomes the side surface of the pouch 10 with the bottom side of the pouch 10 facing down and placed on the mounting surface (to be exact, the front side film 30 or the back side film). It is attached to one of the 40 (positions between the upper and lower first creases 35a and 45a), but as shown in FIG. 14, the pouch 10 is placed on the mounting surface with the bottom side facing down. Positions that will be the top surface of the pouch 10 in the placed state (to be exact, one of the front side film 30 and the back side film 40, the upper first crease processing portions 35a and 45a and the second crease processing portions 35b and 45b. It is also conceivable to attach the spout 60 at the position in between). In the example shown in FIG. 14, the storability of the pouch 10 and the like can be further improved.

Further, as in the example shown in FIG. 15, it is conceivable that the handle hole 28 formed in the seal portion 23 on the top side of the pouch 10 is hooked on the spout 60.
More specifically, in the example shown in FIG. 15, first, the position where the pouch 10 is placed on the mounting surface with the bottom side facing down and becomes the top surface of the pouch 10 (to be exact, the front film 30). Alternatively, the spout 60 is attached to one of the back film 40 (position between the upper first creases 35a and 45a and the second creases 35b and 45b).
Further, the second crease processing portions 35b and 45b of the front side film 30 and the back side film 40 are formed so that the seal portion 23 on the top side of the pouch 10 easily falls to the side where the spout 60 is installed.

Any specific method for forming the crease processing portions 35, 45, 56 may be used, but as an example of the crease processing, the first application proposed by the present applicant in Japanese Patent Application No. 2018-031838. At least one film having a layer and a second layer having a lower elongation than the first layer is coldly compression-molded in the thickness direction at a film stacking portion arranged between the two films in a non-fixed state. This is a so-called CS process in which the film arranged between the two film portions is projected toward the second layer side at the film overlapping portion.

Further, in the second embodiment described above, the crease processing portions 35, 45 and 56 are formed on the films 30, 40 and 50, but the crease processing portions may be formed on any film, for example, a film. The creases 35 and 45 may be formed only on the 30 and 40, and when the inner support member 70 is provided, the creases may be formed on the inner support member 70 as well.
Further, the specific mode such as the position and length of forming the crease processed portions 35, 45, 56 may be arbitrarily set according to the desired overall shape of the pouch 10.
Further, in the second embodiment described above, it has been described that the pouch 10 includes the inner support member 70, but the inner support member 70 itself may not be provided when the pouch 10 is configured.

Next, the pouch 10 according to the third embodiment of the present invention will be described with reference to FIG. Here, since the third embodiment is exactly the same as the first embodiment described above except for a partial configuration, the description of the configuration other than the differences will be omitted.

Since the pouch described in Patent Document 1 is made of a resin film or the like, there is a risk that an operator or the like may drop the pouch during storage or display, resulting in damage to the pouch. For example, when the content is large and the weight is heavy, such as an inner bag for a bag-in-box, it is burdensome for the worker to lift the pouch product containing the contents, and the pouch product is dropped during the work. It is considered that there is a considerable risk of causing it. The pouch 10 shown in the third embodiment is a pouch for the purpose of leaving a history of a pouch impact by an operator or the like on the pouch.

In the third embodiment, for the purpose of leaving a history in the pouch 10 that an operator or the like has dropped the pouch 10 during storage or display of a product or a strong impact has been applied to the pouch 10. A weakened portion 76, which is weaker than the peripheral portion and breaks or is damaged when the pouch 10 is dropped, is formed on the inner support member 70 itself or the fixed portion between the pouch body 20 and the inner support member 70. There is.

As a specific embodiment of such a weakened portion 76, first, it is conceivable to form the weakened portion 76 on the inner support member 70 itself.
In this case, as shown in FIG. 16A, a specific embodiment of the weakened portion 76 is a connecting piece formed between the flow portions 75 of the inner support member 70 by forming a through hole or a slit in the connecting piece. It is conceivable to weaken the strength of a part of the connecting piece, or to form a narrow portion in a part of the connecting piece to weaken the strength of a part of the connecting piece as shown in FIG. 16B. When the weakened portion 76 shown in FIGS. 16A and 16B is completely torn off when the pouch 10 is impacted, or is stretched even if it is not torn off, or when the film constituting the inner support member 70 is made into multiple layers. , Breakage or damage such as peeling of the front and back film laminates occurs on the inner support member 70. By observing this broken or damaged state, it can be recognized that the pouch 10 has been impacted by dropping or the like.

Further, as a specific embodiment of such a weakened portion 76, it is conceivable to form a weakened portion 76 at a fixed portion between the pouch body 20 and the inner support member 70.
As for the specific embodiment in this case, any one may be used as long as it is formed so as to break or be damaged when the pouch 10 is dropped or the like. For example, as shown in FIG. 16 (c), the pouch main body is used. A part with a weak fixing strength is provided in a part of the fixing part between the 20 and the inner support member 70 by a method such as setting a low temperature or pressure at the time of heat welding or reducing the fixing area, and this part is weakened. It may be used as a part 76. When the pouch 10 is impacted, the weakened portion 76 shown in FIG. 16 (c) is partially or completely peeled off, resulting in breakage or damage to the inner support member 70. By observing this broken or damaged state, it can be recognized that the pouch 10 has been impacted by dropping or the like.

Further, in the third embodiment, the films 30, 40, 50 constituting the pouch body 20 can be visually recognized from the outside of the pouch 10 so that the breakage or damage of the weakened portion 76 when the pouch 10 is dropped or the like can be visually recognized from the outside of the pouch 10. A transparent or translucent portion is provided in at least a part of the above.

Further, even if the weakened portion 76 is broken or damaged when the pouch 10 is dropped or the like, the weakened portion 76 is formed in such a manner that the body swelling suppressing function of the pouch 10 by the inner support member 70 is not impaired. desirable.

In the third embodiment thus obtained, the history of the pouch 10 falling or the like can be left in the pouch 10 by forming the weakened portion 76 which is broken or damaged when the pouch 10 is dropped or the like.

Next, the pouch 10 according to the fourth embodiment of the present invention will be described with reference to FIGS. 17 and 18. Here, since the fourth embodiment is exactly the same as the first embodiment described above except for a partial configuration, the description of the configuration other than the differences will be omitted.

Since the pouch described in Patent Document 1 is made of a resin film or the like, if the pouch product containing the contents is placed as it is, the independence may not be maintained due to the flow of the contents. For example, when the content is large and the weight is heavy, such as an inner bag for a bag-in-box, the force applied to the film when the contents flow is increased, so that the independence may be worsened. The pouch 10 shown in the fourth embodiment is a pouch for the purpose of improving independence.

In the fourth embodiment, as shown in FIGS. 17 and 18, a third fixed portion of the pouch body 20 is used for the purpose of improving the independence of the pouch 10 when the pouch 10 is placed on the mounting surface. At least the fixing region between the 26 and the third fixing portion 73 of the inner support member 70 and the fixing region between the fourth fixed portion 27 of the pouch body 20 and the fourth fixing portion 74 of the inner support member 70. On one side (both in this embodiment), a fluid accommodating portion 91 accommodating a fluid such as air in a sealed state is formed.

Specifically, as can be seen from FIGS. 17 and 18, the fluid accommodating portion 91 has the fixed portion 26 and the fixed portion 73 in a part of the fixed region between the fixed portion 26 and the fixed portions 73 and 74. A non-fixed region that does not stick to 74 is formed, and a fluid such as air is contained in the non-stick region in a sealed state.

As shown in FIGS. 17 and 18, the lower end of the fluid accommodating portion 91 has a front side film 30 near the mounting surface when the pouch 10 is placed on the mounting surface with the bottom side of the pouch 10 facing downward. The back side film 40 is set near the bending position, and the upper end portion of the fluid accommodating portion 91 is set near the bending position of the front side film 30 and the back side film 40 on the top side of the pouch 10.
The specific modes such as the positions of the upper and lower ends of the fluid accommodating portion 91 may be arbitrarily determined according to the embodiment.

In the fourth embodiment, a non-fixed region in which the fixed portion 26 and the fixed portions 73 and 74 are not fixed is formed in a part of the fixed region between the fixed portion 26 and the fixed portions 73 and 74, and air is formed. A fluid accommodating portion 91 for accommodating a fluid such as the above is provided. By making it, the fluid accommodating portion 91 may be used. Alternatively, when the inner support member 70 is composed of a multi-layer film, the fluid accommodating portion 91 may be formed by peeling the layers of the film 70 at a position to be the fluid accommodating portion 91 to create a space.

In the fourth embodiment thus obtained, the independence of the pouch 10 when the pouch 10 is placed on the mounting surface can be improved by forming the fluid accommodating portion 91.

Next, the pouch 10 according to the fifth embodiment of the present invention will be described with reference to FIGS. 19 and 20. Here, since the fifth embodiment is exactly the same as the fifth embodiment described above except for a partial configuration, the description of the configuration other than the differences will be omitted.

Conventionally, in a spout pouch having gusset portions on the left and right sides of the pouch, the contents are filled from the filling port at the upper part of the pouch (Patent Document 3: Japanese Patent Application Laid-Open No. 11-314644). In the pouch described in Patent Document 3, bubbles may be generated in the contents in the pouch when the contents are filled. In this case, in order to seal and seal the filling port of the pouch, the foam portion needs to be lifted as the filling progresses, and the foam portion needs to be contained in the pouch when fully filled. That is, the pouch must be provided with a margin space in consideration of the foam portion, and the contents are filled in a small capacity with respect to the size of the pouch, resulting in poor filling efficiency. There is a risk. The pouch 10 shown in the fifth embodiment is a pouch for the purpose of improving the filling efficiency.

In the fifth embodiment, as shown in FIGS. 19 and 20, the inner support member 70 aims to suppress foaming that tends to occur in the pouch 10 when the pouch 10 is filled with contents such as a liquid detergent. The distribution section 75 is formed only in the lower region of the above.

More specifically, in the fifth embodiment, as shown in FIGS. 19 and 20, the distribution unit 75 is provided only in the lower region of the inner support member 70 (the lower half region of the inner support member 70 in the vertical direction). Is formed, and the flow portion 75 is not formed in the upper region of the inner support member 70 (the region of the upper half of the inner support member 70 in the vertical direction).

Then, in the fifth embodiment, as shown in FIG. 20, from the top side of the pouch 10 in which the seal portion 23 is not formed (each film 30, 40, 70 is not heat-welded) at the time of filling the contents. , One space 21a in the content accommodating portion 21 divided by the inner support member 70 is filled with the content from the filling nozzle 77. The contents supplied to one space 21a in the contents accommodating portion 21 are also supplied to the other space 21a in the contents accommodating portion 21 through the distribution unit 75. In the filling nozzle 77, the opening of the nozzle is first arranged near the bottom of the pouch 10, and while filling the contents, the filling nozzle 77 follows the liquid surface of the contents so that the opening does not touch the liquid surface. Move to.

In the fifth embodiment thus obtained, as shown in FIGS. 19 and 20, the distribution unit 75 is provided only in the lower region of the inner support member 70 (the lower half region of the inner support member 70 in the vertical direction). As shown in FIG. 20, it is possible to rectify the flow of the contents at the time of filling the contents, so that the contents that cause foaming such as liquid detergent may be filled. However, foaming during filling can be suppressed. Further, as a result, it is possible to reduce the spare space of the content accommodating portion 21 preset in consideration of foaming of the content at the time of filling, and it is possible to improve the filling efficiency.

In the fifth embodiment, the distribution unit 75 is provided on the lower side of the inner support member 70, but the distribution unit 75 is not limited to the lower side, but is also provided on the upper side as shown in FIG. The foam may be released from the content accommodating portion 21 on the filling side to the adjacent content accommodating portion 21. Further, as shown in FIG. 20 (c), the filling nozzle 77 is arranged close to the inner support member 70, and the contents are poured toward the inner support member 70 so that the contents are aligned with the inner support member 70. It may be filled as follows. Further, by arranging a member having a fine through hole such as a mesh in the distribution unit 75, bubbles can be broken and reduced during distribution of the content distribution unit 75.

Next, the pouch 10 according to the sixth embodiment of the present invention will be described with reference to FIG. Here, since the sixth embodiment is exactly the same as the first embodiment described above except for a partial configuration, the description of the configuration other than the differences will be omitted.

The pouch described in Patent Document 2 is provided with a gripping hole for gripping the pouch with a hand or a finger. In the pouch described in Patent Document 2, a slit penetrating the film is formed in the film to form a gripping hole. In this case, in a pouch product containing the contents, when the user lifts the pouch by passing a hand or finger through the gripping hole, a load is applied to the end of the slit due to the weight of the contents, and the end of the slit is kicked. The slit may tear. In particular, as the weight of the contents increases, the risk is considered to increase.

In the sixth embodiment, as shown in FIG. 21, a user lifts the pouch 10 through a hand or a finger in a region where the films 30, 40, and 70 are heat-welded in the seal portion 23 on the top side of the pouch 10. The handle portion 29 is formed.
The handle portion 29 is formed by forming through slits 29a penetrating the films 30, 40, and 70 in the front and back directions, so that the user's finger can be passed through the holes defined by the through slits 29a. There is.
The through slit 29a is formed as a wide slit having a width in a direction orthogonal to the extending direction thereof.
Each of the films 30, 40, and 70 is formed with a handle piece 29b partitioned from a peripheral portion by a through slit 29a (in other words, located inside the pouch plane direction of the through slit 29a).
A part of the outer edge of each handle portion 29b is connected to a peripheral portion by a bending connecting portion 29c.
The bending connecting portion 29c is formed on the outer edge of the handle portion 29b, which is located on the outer side of the pouch (upper side in the case of the present embodiment). As a result, when the pouch 10 is lifted by using the handle portion 29, the user's fingers come into contact with the films 30 and 40 bent in the vicinity of the bending connecting portion 29c, so that the user's fingers feel pain. It can be avoided.

As shown in FIG. 21, the through slit 29a has an overall shape lacking a part of an annular shape when viewed in a plan view in the front-back direction.
Further, both end portions 29d of the through slit 29a are formed so as to extend toward the inside (lower side in the present embodiment) of the handle piece portion 29b. As a result, when the films 30, 40, and 70 are bent in the vicinity of the bending connecting portion 29c to lift the pouch 10, stress is less likely to be applied to the tips of both ends 29d of the through slit 29a, so that both ends 29d of the through slit 29a are less likely to be stressed. It is possible to prevent the film from breaking due to the stress.

In the sixth embodiment described above, the handle portion 29 is formed at a position where the films 30, 40, and 70 overlap. For example, the handle portion 29 is formed at a position where only the films 30, 40 and 40 overlap. The formation position of the handle portion 29 may be any place.
Further, in the sixth embodiment described above, it has been described that the pouch 10 includes the inner support member 70, but the inner support member 70 itself may not be provided when the pouch 10 is configured.

Next, the pouch 10 according to the seventh embodiment of the present invention will be described with reference to FIG. Here, since the seventh embodiment is exactly the same as the first embodiment described above except for a partial configuration, the description of the configuration other than the differences will be omitted.

The pouch described in Patent Document 3 is provided with a spout at the upper corner of the pouch. As a matter of course, in the pouch described in Patent Document 3, one kind of contents is housed in the pouch and displayed as a pouch product in a store such as a retail store. By increasing the capacity of the contents, the user can use it for a long time with one purchase without purchasing it multiple times. However, for example, in the case of a pouch product such as a liquid detergent or shampoo that also works on the user's taste, the user may desire to change the scent or color while using the contents. The pouch 10 shown in the seventh embodiment is a pouch intended to meet such a desire of the user.

First, in the first embodiment described above, the distribution unit 75 is formed on the inner support member 70, but in the seventh embodiment, the distribution unit 75 is formed on the inner support member 70 as shown in FIG. 22. The inner support member 70 is installed so as to isolate the inside of the content accommodating portion 21 into a plurality of (two in the present embodiment) spaces 21a, in other words, a plurality of inner support members 70 divided by the inner support member 70. It is installed so that the contents do not circulate between the (two) spaces 21a.

Further, in the seventh embodiment, as shown in FIG. 22, spouts 60 are attached to each of the plurality of spaces 21a in the content accommodating portion 21.

In the seventh embodiment thus obtained, the contents are individually accommodated in each space 21a in the contents accommodating portion 21, and the contents accommodated in each space 21a are individually accommodated by using the spout 60. Since it is possible to dispense, for example, different contents are accommodated in each space 21a, and the contents are selected and dispensed according to the user's request, or two or more kinds of contents are dispensed. By blending, the color and scent of the contents can be changed. Alternatively, the two types of contents can be used alternately, and the user can use the one type of contents without getting bored.

In the seventh embodiment described above, one inner support member 70 isolates the inside of the content accommodating portion 21 into two spaces 21a, but two or more inner support members 70 accommodate the contents. The inside of the portion 21 may be isolated into three or more spaces 21a, and in this case, the number of spouts 60 may be arbitrarily determined according to the quantity of the spaces 21a.

Next, the pouch 10 according to the eighth embodiment of the present invention will be described with reference to FIGS. 23 to 25. Here, since the eighth embodiment is exactly the same as the first embodiment described above except for a partial configuration, the description of the configuration other than the differences will be omitted.

Conventionally, there is a pouch in which a spout is provided at the bottom of the pouch and the contents are poured out from the spout (Patent Document 4: Actual Registration 3194684) However, in the pouch described in Patent Document 4, the distance between the pouch and the bottom surface of the pouch is large. If there is, the contents remain in the gap between the spout and the bottom of the pouch when the contents are reduced. Therefore, when trying to pour out the contents to the end, the pouch is manually tilted diagonally so that the contents are directed toward the spout, and the contents are poured out. The pouch 10 shown in the eighth embodiment is a pouch for the purpose of reducing the amount of residual liquid in the pouring.

In the eighth embodiment, as shown in FIG. 23, a hanging portion 92 for hanging and using the pouch 10 is formed, and the pouch 10 is suspended by using the hanging portion 92. By attaching the spout 60 to the position below the pouch 10, the amount of the content (content liquid) C remaining in the content accommodating portion 21 is reduced.

More specifically, in the eighth embodiment, as shown in FIG. 23, the sealing portion 23 (longitudinal direction) in which one of the front side film 30 or the back side film 40 and one of the pair of gusset film 50 is heat-welded. (Near the center), a hanging portion 92 formed as a hole penetrating the seal portion 23 is formed.
Further, as shown in FIG. 23, the spout 60 is attached at a diagonal position of the forming position of the hanging portion 92, and specifically, the gusset portion film 50 paired with the other of the front side film 30 or the back side film 40. It is attached to the seal 23 (near the center in the longitudinal direction) in which the other side of the film is heat-welded.

In the eighth embodiment, as described above, by providing the hanging portion 92 and the spout 60, as shown in FIG. 24, the hanging tool T such as a bolt is inserted through the hanging portion 92 to suspend the pouch 10. When lowered, or as shown in FIG. 25, a hanging tool T such as a bolt is inserted into the hanging portion 92, and one back side of the front side film 30 or the back side film 40 is supported by a vertical wall. When the pouch 10 is hung, the spout 60 comes to the lower side of the pouch 10 (content storage unit 21), so that the contents remain in the content storage unit 21 even if the pouch 10 is not manually tilted. The amount of the substance (content liquid) C can be reduced.

In the eighth embodiment described above, the hanging portion 92 has been described as being formed in a hole shape through which a hanging tool T such as a bolt shown in FIG. 23 or the like is inserted. Any aspect may be used as long as the pouch 10 can be suspended. For example, the suspending portion 92 may be configured from a hook-shaped component fixed (adhered or welded) to the pouch 10. ..
Further, in the eighth embodiment described above, the installation positions of the hanging portion 92 and the spout 60 have been described as described above, but the hanging portion 92 and the spout 60 are installed at the suspension portion 92. Anything may be used as long as the spout 60 comes to the lower side of the pouch 10 with the pouch 10 suspended.
Further, in the eighth embodiment described above, it has been described that the pouch 10 includes the inner support member 70, but the inner support member 70 itself may not be provided when the pouch 10 is configured.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the present invention described in the claims. It is possible. Further, the pouch 10 may be formed by arbitrarily combining the configurations of the plurality of embodiments described above and the modifications described later.

For example, in the above-described embodiment, the pouch 10 is described as being housed and operated in an outer case (not shown) when it is used, displayed, or transported, but it is inside the outer case (not shown). The pouch 10 itself may be used, displayed or transported without being housed.

Regarding the specific aspects of the films 30 to 50 constituting the pouch body 20, a heat-weldable layer such as an olefin-based film of low-density polyethylene or polypropylene or a polyester-based film such as PET (polyethylene terephthalate) is provided on at least one side. Any layer may be laminated on the single film of the heat-welded layer or the heat-welded layer as long as it has. Any material may be used to form the laminate, and any material may be arbitrarily formed by laminating known polyesters such as PET and PBT (polybutylene terephthalate), polypropylene, polyamide, polyethylene, aluminum foil and the like.
Further, in the above-described embodiment, the pouch body 20 has been described as being formed of four resin films of a front side film 30, a back side film 40, and a pair of gusset film 50, but the pouch body 20 is configured. The specific aspect of the pouch body 20 such as the number of resin films to be formed is not limited to the above, and for example, one resin film (that is, the front side film 30, the back side film 40, and the gusset film 50 are integrally integrated. The formed resin film) may be wound in a tubular shape and heat-welded at a predetermined location to form any film.
Further, in the above-described embodiment, the pouch body 20 has been described as being formed as a so-called horizontal gusset type pouch having gusset portions 22 formed on both sides thereof. However, what is the specific aspect of the pouch body 20? It may be any, for example, a so-called bottom gusset type pouch having one gusset portion 22, a pouch having a total of three gusset portions 22 on both sides and the bottom, and the like.

Further, in the above-described embodiment, the spout 60 has been described as being attached to the seal portion 23 on the top side of the pouch 10, but the specific arrangement of the spout 60 is not limited to the above, and for example, FIG. As shown in FIG. 6, the spout 60 may be attached to the gusset portion 22 (the gusset portion film 50) by means such as heat welding. In the examples shown in FIGS. 5 and 6, a third heat-welded region 53 to be heat-welded to the spout 60 is formed on one of the gusset film 50. In FIG. 6, the heat-welded region in which each film 30 to 50 is heat-welded is represented by a dot pattern. Similarly, as shown in FIGS. 12 and 21, the spout 60 may be attached to the front side film 30 and the back side film 40. Further, the pouch 10 may be configured so as to form a spout by cutting a part of the pouch body 20 without providing the spout 60 itself.

Further, in the above-described embodiment, the inner support member 70 has been described as being configured as a resin film, but specific embodiments of the inner support member 70 include the first fixing portion 71 and the first fixing portion 71 shown in FIGS. 3 and 6. Anything may be used as long as it has two fixing portions 72, and for example, the inner support member 70 may be formed in a string shape or a band shape. The inner support member 70 is preferably formed of a flexible (elastic) material.
When the inner support member 70 is made of a resin film, the inner support member 70 may be formed of a resin film having a structure different from that of the films 30, 40, and 50 constituting the pouch body 20, but the pouch 10 is manufactured. From the viewpoint of reducing the cost, it is preferable to form the inner support member 70 from the resin film having the same structure as the films 30, 40, and 50 constituting the pouch body 20.
Further, the method of fixing the inner support member 70 to the pouch body 20 is not limited to the above-mentioned heat welding, and may be any method such as adhesion using an adhesive.

Further, in the above-described embodiment and the like, when the distribution unit 75 is formed on the inner support member 70, it has been described that the distribution unit 75 of the inner support member 70 is formed in a hole shape. The embodiment may be any as long as the contents can be distributed. For example, as shown in FIG. 7A, the distribution unit 75 has a notch shape in which the outer edge of the inner support member 70 is cut out. May be formed.
Further, in the example shown in FIG. 3, a plurality of round hole-shaped distribution units 75 are arranged side by side in two rows, but when the distribution units 75 are formed in a hole shape, the specific quantity of the distribution units 75 and Any arrangement or shape may be used. For example, as shown in FIG. 7 (b), a plurality of round hole-shaped distribution portions 75 may be arranged in a staggered manner, and as shown in FIG. 7 (c). In addition, the distribution section 75 may be formed in a long hole shape. Further, it may be in the form of a mesh (not shown) having fine holes through which the contents can be distributed.
Note that, for example, as in the examples of FIGS. 8 (d) and 8 (e) described later, the inside of the content accommodating portion 21 is not divided into a plurality of spaces by the inner support member 70 as in the present embodiment. In the case, that is, when a gap for circulating the contents is formed between the inner support member 70 and the inner side surface (each film 30 to 50) of the contents accommodating portion 21, the circulation portion 75 is formed. It does not have to be.

Further, in the above-described embodiment, the first fixed portion 24 of the pouch body 20 is a part of the sealed portion 23 on the top side, and the second fixed portion 25 is a part of the sealed portion 23 on the bottom side. However, the specific positions of the first fixed portion 24 and the second fixed portion 25 may be any specific positions as long as they face each other with the content accommodating portion 21 in between. It can be appropriately changed according to the desired effect of suppressing the swelling of the pouch body 20. For example, as in the modified examples shown in FIGS. 8 (d) and 8 (e) described later, the first fixed portion 24 is a part of the inner surface of the front side film 30, and the second fixed portion 25 is the back side. It may be a part of the inner side surface of the film 40, the first fixed portion 24 is a part of the inner side surface of one gusset portion film 50, and the second fixed portion 25 is the other gusset portion. It may be a part of the inner surface of the film 50.

Similarly, in the above-described embodiment, the third fixed portion 26 of the pouch body 20 is a part of the inner side surface of the front side film 30, and the fourth fixed portion 27 is a part of the inner side surface of the back side film 40. However, the specific positions of the third fixed portion 26 and the fourth fixed portion 27 may be any specific positions as long as they face each other with the content accommodating portion 21 in between.

Further, the specific quantity and arrangement of the inner support members 70 and the fixing mode to the films 30, 40, 50 may be any as long as they have the first fixing portion 71 and the second fixing portion 72.
For example, in the example shown in FIG. 8A, the adhesion area of the inner support member 70 to the films 30 and 40 is larger by the amount of the A portion as compared with the example shown in FIG. The fixing strength of the inner support member 70 can be improved. The mode of the pouch body 20 and the inner support member 70 in the example shown in FIG. 8A is the same as the example shown in FIG. 6 except for the above-mentioned A portion.
Further, in the example shown in FIG. 8B, two inner support members 70 are arranged side by side in the horizontal direction, and the inner support members 70 are fixed to the films 30 and 40, respectively. The mode of the pouch body 20 and the inner support member 70 in the example shown in FIG. 8 (b) is the same as the example shown in FIG. 8 (a) except for the quantity of the inner support member 70.
Further, in the example shown in FIG. 8 (c), the inner support member 70 has a first film portion (not shown) and a first film formed in the same manner as the inner support member 70 in the example shown in FIG. 8 (a). It is composed of a second film portion (not shown) formed so as to intersect the portions (not shown) in a cross shape (integrally or separately). The second film portion (not shown) is fixed to the inner surface of the front side film 30, the inner surface of the back side film 40, and the inner surface of the pair of left and right gusset film 50, and the distribution portion 75 is formed. The mode of the pouch body 20 and the inner support member 70 in the example shown in FIG. 8 (c) is shown in FIG. 8 (not shown) except that the inner support member 70 has a second film portion (not shown). It is the same as the example shown in a).
Further, in the example shown in FIGS. 8 (d) and 8 (e), one or a plurality of inner support members 70 are fixed to the inner surface of the front side film 30 and the inner surface of the back side film 40, respectively. (Not shown). The mode of the pouch body 20 and the inner support member 70 in the example shown in FIGS. 8 (d) and 8 (e) is the same as the example shown in FIG. 8 (a) except for the mode of the inner support member 70 and the like. For example, by providing a heat welding layer on one side of the inner support member 70, the heat welding layer can be fixed to the inner surface of the front side film 30 and the inner surface of the back side film 40, respectively.
Further, although not shown, in the examples shown in FIGS. 1 to 4 and the examples shown in FIGS. 5 and 6, the third fixing portion 73 and the fourth fixing portion 74 do not have to be provided on the inner support member 70, in other words, the first The inner support member 70 may be fixed to the pouch body 20 only by the 1 fixing portion 71 and the second fixing portion 72.

Further, in the example shown in FIGS. 1 to 3, as shown in FIG. 9, the gusset film 50 is folded in half, and the bent portion is formed between the front side film 30 and the back side film 40. It is arranged so as to face the accommodating portion 21 side, and is heat-welded to the front side film 30 and the back side film 40.
However, as in the modified examples shown in FIGS. 10 and 11, at least one of both ends of the gusset film 50 in the longitudinal direction (in this modified example, the end on the top side to which the spout 60 is mounted). The gusset film 50 is placed in the longitudinal direction (an angle of 45 ° in this modification) so that the corners of the gusset film 50 located on the content accommodating portion 21 side approach the outside of the pouch body 20. You may fold it diagonally, or you may fold it so that the corners are on the fold side of the gusset film 50. As a result, as shown in FIGS. 10 and 11, by arranging the spout 60 in the space vacated by bending the gusset film 50 diagonally, the spout 60 can be arranged closer to the end. Therefore, when the pouch 10 is used, when the pouch 10 is installed on the mounting surface with the top of the pouch 10 equipped with the pouch 60 facing laterally, the pouch 60 is positioned at a lower position. Therefore, it is possible to prevent a large amount of contents from remaining in the pouch 10.
Reference numerals 54 in FIGS. 10 and 11 indicate a fourth heat welding region 54 in which parts of the gusset film 50 that are bent and opposed to each other are heat welded to each other.
Further, in the examples shown in FIGS. 10 and 11, the gusset film 50 has two notched penetrating portions 55 on its short side, and the two penetrating portions 55 are for the gusset portion. The films 50 are formed so as to overlap each other in a folded state. When such a penetrating portion 55 is formed, as can be seen from FIGS. 10 (b) and 11 (b), one of the front side film 30 and the back side film 40 (in the example of FIGS. 10 and 11) is formed through the penetrating portion 55. The front side film 30) and a part of the gusset film 50 indicated by reference numeral 56 can be heat-welded. Although not shown, the penetrating portion 55 may be formed in a hole shape instead of a notch shape. In this case, the penetrating portion 55 is formed near the short side of the gusset film 50. Further, the number of penetrating portions 55 is not limited to two, and may be any, for example, four, six, or the like.
Further, as in the example shown in FIG. 11, the gusset portion films 50 may be heat-welded to each other in the triangular portion 57 formed by further diagonally bending the gusset portion film 50 folded in half. In this case, it is possible to prevent the contents from getting into the folded gusset film 50 in the state after the pouch 10 is made. In the example shown in FIG. 11, the gusset film 50s are heat-welded to each other at the portion 57 before the gusset film 50 is heat-welded to the front side film 30 and the back side film 40.
The heat welding location between the front side film 30, the back side film 40, and the gusset film 50 is not limited to the example shown in FIG. 10 and the example shown in FIG. 11, and may be arbitrarily set according to the embodiment. Just do it.
